Converting byte[] of binary fixed point to floating point value
I'm reading some data over a socket. The integral data types are no trouble, the System.BitConverter methods are correctly handling the conversion. (So there are no Endian issues to worry about, I think?)
However, BitConverter.ToDouble isn't working for the floating point parts of the data...the source specification is a bit low level for me, but talks about a binary fixed point representation with a positive byte offset in the more significant direction and negative byte offset in the less significant direction.
Most of the research I've done has been aimed at C++ or a full fixed-point library handling sines and cosines, which sounds like overkill for this problem. Could someone please help me with a C# function to produce a float from 8 bytes of a byte array with, say, a -3 byte offset?
Further details of format as requested:
The signed numerical value of fixed point data shall be represented using binary, two's-complement notation.For fixed point data, the value of each data parameter shall be defined in relation to the reference byte. The reference byte defines an eight-bit field, with the unit of measure in the LSB position. The value of the LSB of the reference byte is ONE.
Byte offset shall be defined by a signed integer indicating the position of the least significant byte of a data element relative to the reference byte.
The MSB of the data element represents the sign bit. Bit positions between the MSB of the
parameter absolute value and the MSB of the most significant byte shall be equal in value to the sign bit.
Floating point data shall be represented as a binary floating point number in conformance with the IEEE ANSI/IEEE Std 754-2008. (This sentence is from a different section which may be a red herring).
This question is impossible to answer at present. In order to convert between two different formats, you need precise definitions of those formats. Not only have you not supplied a definition for the fixed-point format (floating point is defined by IEE754), your questions suggests that you do not actually have such a definition. You need to get this information.
If it's a simple fixed point number you can parse it as int, and then multiply it with a certain constant. For example with 2^-16 if the fixed-point as 16 fractional bits.
@CodeInChaos That's true, but OP doesn't know the format, not even after his update.
Ok, after asking some questions from a local expert on the source material, it turns out CodeInChaos was on the right track...if the value is 8 bytes with a -3 byte offset, then I can use BitConverter.ToInt64 / 256^3, if it is 4 bytes with a -1 byte offset then BitConverter.ToInt32 / 256 will produce the correct answer. I guess that means BitConverter.ToXXX where XXX is signed is smart enough to handle the twos-complement calculations!
Thanks to those who tried to help out, I thought it couldn't be too complicated but getting that 256 offset from the reference document wording was very confusing:-)
If you answer your own questions that's OK, then also mark it as "the answer", otherwise it will keep turning up in the "unanswered" queries.
System.BitConverter works very slow, so if performance is significant to you, i'd recommend to convert bytes to int by yourself (via logical shifts).
Also, please specify in what exact format floats are sent in your protocol.
Since when is BitConverter slow? Do you have any stats on this?
I found that some years ago, in implementation of symmetric encryption algorithm. I can not show any numbers right now, can only say that the difference was very significant.

Arm is proud to announce the initial release of Tarmac Trace Utilities, an open-source code base for analyzing and browsing trace files in Tarmac trace format.
“Tarmac” is a textual format that logs the instructions executed by a CPU, and their effects. It lists every value written to a register, and every value read and written from memory. and other events such as interrupts and exceptions. It is generated by a range of Arm products, including Fast Models and Cycle Models, and even direct simulations of a specific CPU from its RTL. It might look like this, for example:
These trace files are very detailed, but not always easy to read. They have to list events in chronological order, and that is not always the order the reader finds most useful. The simplest way to examine one is to use an ordinary text editor, or a file viewer like less. But suppose you need to know what was in a particular part of memory at a certain point in time? It is hard to find that out using only a text editor. You would have to search back through the trace file for the most recent memory-write operation that touched the address in question – and that might not be easy to find, because memory writes can be done in lots of ways. (For example, your piece of memory might have been written all at once, or 1 byte at a time, or as a small part of a larger write.)
If you spent a lot of time trying to figure out what had happened in Tarmac traces, you would like some software to help you with tasks like that.
Tarmac Trace Utilities is a suite of tools that give you that help. They begin by reading your trace file and building up an index alongside it, which records the known state of the system at every point in the trace. From that index file, it is easy to look up answers to questions like "What was in memory location X / register R at line N of the trace?", or "What was the last instruction that wrote to that memory and register?", or "Which parts of memory changed between lines N and M?"
Then, each tool uses that same index file in a different way. Some of them produce reports and summaries as output; alternatively, you can interactively browse the trace and see what is going on in detail.
The biggest tool in Tarmac Trace Utilities is tarmac-browser. This lets you page through a trace file just as if it was in an ordinary text editor or file viewer. But wherever the cursor is, the browser shows you the current state of all the registers. It also shows the contents of memory as well, if you ask it to:
In this screenshot, the topmost pane shows the contents of the trace file itself, with the horizontal line indicating the current position we are looking at. The next pane shows the state of all the registers, as of the point in time indicated by that horizontal line. The bottom pane shows the contents of memory in the region of the stack pointer. These displays make it easier to understand what is going on in the code.
(But the tool can only show registers and memory that have been mentioned in the trace file. For example, nothing in the trace before this point has shown any value being written into r4. Therefore, the browser cannot show the contents of r4 at this location, because the trace file does not specify it. Similarly, locations in memory are marked with ?? if nothing in the trace has ever accessed them.)
The browsing tool also provides a way to quickly jump to trace positions that might be of interest. For example, suppose you want to know why some register or piece of memory had a particular value. (Perhaps it was a value you were not expecting.) Then tarmac-browser provides keystrokes that will jump to the most recent instruction that wrote to the register or memory in question.
Another handy feature is the ability to “fold up” function calls in the trace. This will hide the details of what happened inside the function. You see the call instruction, immediately followed by the instruction after the function returned. So it looks as if the call instruction did the whole job itself. (Rather like stepping over a function call in a debugger.)
In addition to this interactive browsing tool, Tarmac Trace Utilities can reuse the same analysis and indexing system to produce reports and translations of the trace.
For example, we have written a tool that will translate a Tarmac trace into IEEE 1364 Value Change Dump format (VCD files). That is a standard format that other software already understands. In particular, you can view a VCD file graphically using tools like gtkwave.
Several of the other tools use the fact that the index has to identify function calls and returns, for the browser's folding feature. So they reconstruct the whole function call tree from the same data, and do useful things with it. For example, we provide a tool that simply prints the whole tree, with line numbers showing where all the calls start and end. (This lets you find the part of the trace you want to examine in more detail.) Also, we have provided tools that produce profiling information about where all the time is spent in the trace. One writes out its own simple human-readable format; another generates output that can be consumed by Brendan Gregg's "flame graph" system.
Those are only the starting set. The tools are open-source, and it does not take a lot of code to add further reporting utilities. There is no end of scope for other things you could write along these lines. Statistics about memory access patterns or register usage? Reconstituting the logged memory contents into a core-dump or image file? Finding copies of sensitive data that were not erased when a secure function terminated? Translate Tarmac trace into other emulators' trace formats so you can see where two models disagree on something? We would love to see what other people come up with.
The tools are available on Github, at ARM-software/tarmac-trace-utilities. They are open-source, under the Apache-2.0 license.

“But guess what: consumers spend more money each year on AirPods than healthcare spends each year on EMR! And because of IT, consumers have been gaining new capabilities much more rapidly than the healthcare system.” This is some fun thinking on innovation in large organizations and systems. First, are you actually spending the resources (time, money, and attention) to change things. Second, are you solving simple problems that have big productivity/improvement gains.
“According to the report, only 7% of surveyed government leaders said their organization achieved its digital transformation objectives. " Original source: Most Government Orgs Fail to Meet Digital Transformation Objectives, Report Finds
The charitable guidance on what “shift left” means is: operations and security people working closer with developers, being friendly with them, and vice-versa. More or less it’s that lean idea of “move the decisions closer to where the work is actually done.” The phrase has gotten blown up to mean more than the original DevOps think (have developers put in work to make their apps run better in production, and have ops people work with developers to do so) to mean any activity that’s working closer with “developers” rather than in some waterfall-like, impersonal process before or after developers.

What I’ve found is they tend to sometimes have the same sort of meetings and they don’t really change the way that they think about how they’re empowering their staff to be more mindful of being involved and having responsibility with their products. The other thing to pay attention to is making sure you’re actually transforming the way your organization is formed.
I frequently give a talk on “what’s the deal with VMware and software development?” Here’s my script/storyboard for one I’m going to give next week. Sometimes I’m told “don’t make this a vendor talk,” which, as you may recall, dear reader, actually means “don’t be boring.” In this one, I was asked to talk directly to what VMware does for software developers, so you’ll see that. If you like it, you should come check out the discussion next week, be won’t be just me and I’m looking to forward to learning from my co-talker.
You can start to sound too much like an out of touch old person if you start saying things like “oh, we already did that back in my day.” Once people flip your bozo bit, then most anything you say get dismissed. “PaaS” is in this category now: you can’t go around saying that the focus on and conversation about “developer experience” is, like, PaaS. If you’re working on building an integrated stack of frameworks, middleware, tools, and even developer tooling on-top of cloud/kubernetes, you can’t call this PaaS.
Here’s what I’ve learned in doing 30 (maybe more like 40?) executive events in person and online over the past four or so years. Over my career, I’ve done these on and off, but it’s become a core part of my job since moving to EMEA to support Pivotal and now VMware Tanzu with executives. At these events, I learn a lot about “digital transformation,” you know, how people at large organizations are changing how they build software.
Here’s a write-up from myself and JT of a new trend in the kubernetes/DevOps/app dev world: developer portals. With people building out the appdev layer on kubernetes (or “DevX”), many organizations are looking at how they support all the tools and internal community for developers. What’s interesting, and new, about projects like Backstage (now in the CNCF, so pretty closely tied to “we’re running our apps in kubernetes” strategies) is that backstage is looking to add tools right along side the usual “knowledge base” and project management stuff you get for internal dev portals, sites, “Confluence” stuff.
I like this point from a recent write-up of the US Army’s software development transformation: He added that the technology being developed is often secondary. "A lot of times, people get really caught up on what type of software you're developing, and we look at it as the software that we're developing is the intermediate step," he said. Instead, the desired result is having a slew of technology-savvy professionals or "
When we standardized and enforced controls in the CI/CD pipeline the quality improved dramatically. Everyone knew the standards they were held to. “Global Bank” Here is an April 2020 McKinsey report that tries to show a relationship between being good at software and making money. I don’t know math enough to judge these kinds of models (as with the DevOps reports too), but, sure! Here’s their relative ranking of how various developer tools and practices help:

It's only a couple of days left before the translation freeze date (9th
of April). All the community translation contributors have been working
hard towards 100% completion rate. We will need all package maintainers'
support on making sure we are translating the latest POT files and our
completed translation will be packaged in the final build.
I have been keeping an eye on the po files but I can't be sure if pot
files are the lastest. It would be such a shame to miss the cut not
because we are unable to do it but because we are unaware of the changes.
I just refreshed the anaconda translations on rhlinux.redhat.com. This
added ~ 3 strings for the new languages which are now "supported" and
also seems to have fuzzied 2 or 3 (one appears to be a new language, the
other appears to be tweaked SELinux wording)
I'll try to pull in any translation changes through Friday to give as
much of a chance as possible to get these few translations in for
testing with test3.
Also, as of now, the language list for installation in FC2 should be
considered frozen. The following languages are included:
The following languages seem to have sufficient translations (or are
very close) but are not included due to the lack of a suitable font in
Fedora Core. If you know of a font for one of these languages that is
under a suitable license for distribution with Fedora Core, it would be
good to work on getting that into FC3 (it's never to early for the bug
report asking for it filed against distribution :)
Since this has now come up a few times, the branch of
system-config-packages being shipped is still the
redhat-config-packages-1_1_x branch in CVS. So for translations to be
added, they need to be done on this branch.
from the initscripts module, there's a hard to translate string (for
msgid "punching nameserver $nameserver through the firewall"
The problem is the meaning of "punch (to)" in this sentence, any hints?
I checked other translations but they differ a bit. The Swedish one
translates it something like "let it pass through" (släpper igenom), and
the french one by "Inserting" (Insertion). Curiously the Italian
translation uses the same verb (punching) in English.
Me and some of the member from Linux User Group of BiH are extremly interested in translating Fedora on bosnian language. Please can you tell us where to find .pot files for the translation and what to do after we finish the translation.

As I've seen at the schedule:
that the translation deadline is 9th April. Then the 19th April is the
translation build freeze.
What's the difference between them? Is that no translations done _after_
the 9th of April will be included in FC 2 final release?
Will the translation build freeze assure that _all_ translations done
(to that date) are included in FC 2? Or the translators still have to
bug the maintainers so they will include them?
For the Red Hat guys and girls:
I reported a bug (19525) because my language is not included in anaconda
installer. I'm affraid that since I labeled it as "enhancement" it might
not be considered for being "solved" before FC 2 final release. What's
your opinion here?

An experimental C compiler.
This is a project that attempts to become a fully fledged C compiler. It is currently Turing Complete and can be linked in to any other library.
It currently has no support for C's type system, all types are just 64-bit numbers. It has no structs, unions, or enums. All pointers are the same as int. Because of the lack of a type system but the need to know when to allocate a variable, a type must be given to declare a variable but that type is ignored.
You can clone the git repository with the following command:
git clone https://github.com/kcolford/mongoose.git
Access to a distribution tar ball is currently only available through someone who has already downloaded a clone of the repository.

A copy of the license is included in the section entitled "GNU Free Documentation License".
In order to use this project you need the following list of installed programs,
- Doxygen+ (at least version 1.8)
- GCC (preferred, although any C99 compiler should work)
- Valgrind (Optional, only for running test suites)
*: Only required if you're a developer or acquired the source from a source repository.
+: Only required for generating documentation.
How to Set Up
The first step to working on or using Mongoose is if you retrieved the sources from a checkout repository you have to run the bootstrap script like this,
With this done, you can now run the configure script and make,
./configure && make
For more information, read the INSTALL file distributed with this package.
What To Do
If you don't know how Mongoose works, read through the documentation. It has all been generated with Doxygen and thus should be easy to generate read through. To generate the documentation, just run:
If you can't think of something to work on, see the Doxygen generated Todo List.
Alternatively, you can work on Mongoose's general documentation in the README.md.
A Note on Extra Documentation
Additional documentation was provided by gnulib in TeXinfo format. This is temporarily translated into markdown by the Perl script texi2md.pl and then fed into Doxygen's native markdown processor.
The texi2md.pl script is distributed along with the source code for Mongoose and can be found in a git repository at https://github.com/kcolford/texi2md. It also only alters the TeXinfo markup (translating it to markdown). Thus it satisfies all requirements of verbatim copying as described by the GNU Free Documentation License.

FreeSurfer Release Notes
These Release Notes cover what's new in a release, and known issues. See the download and install page for the current stable release.
16 November 2016
Freesurfer version 6.0-beta is a beta release to the Freesurfer community to help identify bug fixes and other unknown issues before the release of Freesurfer version 6.0
- Brain networks (cognitive components) estimated from 10449 Experiments and 83 tasks in the Brainmap database are released in MNI152 and fsaverage space:
- There are three sets of data (networks+auxiliary information) that are released: (1) Probability that a task would recruit a component (csv files), (2) Probability that a component would activate a voxel/vertex, (3) quantitative measures of functional specificity and flexibility (i.e., whether a voxel/vertex specializes for a specific cognitive component or supports multiple components).
- The volumetric maps + csv files are found in average/Yeo_Brainmap_MNI152/. See Yeo_Brainmap_MNI152_README in directory for more details.
- The surface maps are found in the subjects/fsaverage/label directory. See Yeo_Brainmap_fsaverage_README in directory for more details.
- Substructure Segmentation:
New dedicated longitudinal pipeline for subfield segmentation - See LongitudinalHippocampalSubfields
- Fix for time point addition (see bug in 5.3)
TRACULA: see TRACULA release notes
- Matlab Linear Mixed Effects Tools:
- Updated Matlab LME tools to newer Matlab versions
- Allow missing Parallel Toolbox (process sequentially)
- minor improvements to F-test
- Improved dice scores between the aseg and the manual labels of 26 GE and Siemens subjects.
- FSFAST now supports B0 distortion correction and Combined-Volume-Surface (CVS) registration
- NEW! PETSurfer - integrated PET, Partial Volume Correction, and kinetic modeling analysis
- mri_convert can now read gradient tables and b-value tables from the headers of DICOM diffusion data
- mri_glmfit computes the partial Pearson correlation coefficient (pcc.mgh)
recon-all now produces aseg.mgz (subcortical atlas) with Hi-Res data (<1mm). The -hires flag is still necessary to include with recon-all when hi-res data is input. Changes to mri_normalize, mri_em_register and mri_watershed were made to support this feature.
- Improved accuracy of ?h.cortex.label
- Improved prevention of surfaces from crossing into the contralateral hemisphere
- bbregister now uses the FS mri_coreg program by to initialize BBR. FSL or SPM/matlab are no longer needed. mri_coreg is based on spm_coreg and gives very similar results as to when spmregister is run.
- mri_fdr -- command line program to compute and apply the false discovery rate algorithm
Fixed the libcrypt issue with OpenSuse linux platforms
Parallelization: a new flag was introduced which enables two forms of compute parallelization that significantly reduces the runtime. As a point of reference, using a new-ish workstation (2015+), the recon-all -all runtime is just under 3 hours. When the -parallel flag is specified at the end of the recon-all command-line, it will enable 'fine-grained' parallelized code, making use of OpenMP, embedded in many of the binaries, namely affecting mri_em_register and mri_ca_register. By default, it instructs the binaries to use 4 processors (cores), meaning, 4 threads will run in parallel in some operations (manifested in 'top' by mri_ca_register, for example, showing 400% CPU utilization). This can be overridden by including the flag -openmp <num> after -parallel, where <num> is the number of processors you'd like to use (ex. 8 if you have an 8 core machine). Note that this parallelization was introduced in v5.3, but many new routines were OpenMP-parallelized in v6. The other form of parallelization, a 'coarse' form, enabled when the -parallel flag is specified, is such that during the stages where left and right hemispheric data is processed, each hemi binary is run separately (and in parallel, manifesting itself in 'top' as two instances of mris_sphere, for example). This requires, of course, at least 2 cores to be available on a machine, although multicore machines are the standard nowadays. Note that a couple of the hemi stages (eg. mris_sphere) make use of a tiny amount of OpenMP code, which means that for brief periods, as many as 8 cores are utilized (2 binaries running code that each make use of 4 threads). In general, though, a 4 core machine can easily handle those periods. Be aware that if you enable this -parallel flag on instances of recon-all running through a job scheduler (like a cluster), it may not make your System Administrator happy if you do not pre-allocate a sufficient number of cores for your job, as you will be taking cycles from other cores that may be running jobs belonging to other cluster users.
- Bug fix in mri_ca_register that prevented unfolding of lattice and caused many hours of unnecessary unfolding and also stopped warp from evolving.
- Added code for Wash. U. HCP to settle white surface near maxima in second directional derivative if -first_wm_peak is specified (off by default).
- On Ubuntu platforms, you may encounter the error "freeview.bin: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory." Freeview will work fine if you install libjpeg62-dev and run:
sudo apt-get install libjpeg62-dev
- 'recon-all -make all' may fail when it reaches the step requiring the '?h.white.preaparc' file. (Will be fixed in final v6 release)

GH-25025: [C++] Build core compute kernels unconditionally
This includes the core compute machinery in libarrow by default - in addition to all cast kernels and several other kernels that are either dependencies of cast (take) or utilized in libarrow/libparquet (unique, filter). The remaining kernels won't be built/registered unless ARROW_COMPUTE=ON (note that this would slightly change the option's meaning, as currently, nothing in arrow/compute is built unless it's set).
Initially this was more substantial as the original goal was to build the extra kernels as a shared library (suggested in the orginal issue). After some discussion in the issue thread, I opted not to do that - primarily because I can't personally see the utility of a separate lib here, even ignoring the complexity it introduces. However, there may be a good reason that simply hasn't occured to me.
Closes: #25025
One thing I haven't decided is how to deal with the compute unit tests since most of them make heavy use of the extra kernels, so a good chunk of them will fail without them. Easiest option would be force ARROW_COMPUTE=ON if ARROW_BUILD_TESTS=ON (not the worst idea in the world, i guess - as this is a packaging-focused feature). Alternatively, we could just not build the tests in question - although that would include most of the tests in compute/exec.
(Also, I'll look into the unity build failures - not quite sure what's going wrong there...)
cc @felipecrv
This isn't enough to close the issue, right? Do you want to associate this one with a sub-issue of #25025 so you can merge it before working on the shared library setup?
Well to be fair, that might still be the right move as it'd be easy to make that a follow-up PR if we decide to go down that road (assuming we get the library boundaries right in this one).
The goal is to eventually reduce the size of the "core" library right? Do we have any idea how slim this set of baseline kernels is compared to the full set?
Do we have any idea how slim this set of baseline kernels is compared to the full set?
Here's what would be present in the default build:
array_filter
array_take
cast
dictionary_encode
drop_null
filter
indices_nonzero
take
unique
value_counts
There are currently 240 kernels in the full set, so it's a pretty deep cut.
Do you want to add a CI job (or does one already exist?) that builds without ARROW_COMPUTE to ensure basic functionality (e.g. parquet reading/writing and csv reading/writing) still works?
That would be a good idea, yes. AFAIK none of the existing jobs build without ARROW_COMPUTE. Even if they did, the CSV writer/STL tests wouldn't be included and libparquet wouldn't be built at all.
This failure looks related: https://github.com/apache/arrow/actions/runs/4247620924/jobs/7385865305
Perhaps just a changing of include orders has angered the unity build gremlins in some way. Given the two implementations are identical maybe we could put them in util_internal.h?
I still need to add the CI job, but in preparation, I set things up so that certain tests won't be built without the complete kernel registry - so we wouldn't need any special ctest flags to avoid expected failures.
The unity build redefinition errors should be fixed now. Most of the problematic code in scalar_round.cc was actually completely unused, so I just removed it.
@felipecrv / @lidavidm I haven't been following the discussion on #25025 very closely. However, this change seems good. I assume we want to proceed with it?
Yes, either way, I think this is a necessary first step before we can unbundle the kernels + I hope it is easier to review this way

Linux desktops are like a box of chocolates - you never know what you’re going to get. One day, you’re working on a sleek and stylish desktop, and the next day, you’re staring at a screen that looks like it was designed in the 90s. But that’s the beauty of Linux - it’s unpredictable, quirky, and always keeps you on your toes.
Personally, I find Gnome the most usable desktop. Things just works - it stays out of my way, and apps work together with harmony, without causing any issues. Want to login to Vscode with Github? Just click yes, and gnome will open your preffered default browser automatically, login to Github, close the tab, and switch back to vscode app and log you in successfully.
However, sometimes I prefer Hyprland over Gnome. Maybe its because it looks cool, maybe you can customize it a lot, maybe it just has quality of life animations and customizable keybinds. But for me, its because Hyprland doesn't hook any keybind by default. And that includes the Win/Super key. It's just perfect for VM Guis and passing my inputs like the win key to open the windows start menu pretty easily, whereas Gnome would open its own overview panel when clicking the win key.
So, without further ado - Start by having GNOME preconfigured/already installed and ready to use.
I suggest using Fedora Workstation, it comes with Gnome desktop by default, unless you choose some other flavour.
BTW, many suggest to use other login display managers like SDDM, but I didn't find any problems using the default GDM login manager that comes with GNOME desktop by default.
For illustration purposes, I will be running Fedora Default/Gnome flavour ISO inside a VM (but dont worry, I still use Fedora on the real setup too lol)
So anyways, after setting up Gnome desktop properly, you should start by installing Hyprland package.
On Fedora, its as easy as installing
sudo dnf install hyprland .
If everything goes perfect, you can log out to the login screen of GDM. Select your account if not already, and you will see a small "cog" icon at the bottom right. Clicking it will show available Desktops that you can use.
We now need to setup gnome polkit integration. Hyprland docs suggested kde integration, but since we want Gnome one, start by pressing
win+Q to open up kitty terminal. Type in
sudo dnf install polkit-gnome to do so. For other linux distros out there, consider finding a similar package by search online.
If you are setting Hyprland for the first time, you will get a yellow warning popup at the top of the screen. To remove it, you need to install a code editor like
vim, edit the config file at
~/.config/hypr/hyprland.confand remove the
Now the hard part - We need to setup passwords to be synced with Gnome desktop too.
If you had previously googled it, ArchWiki would say the binary was installed at
/usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1, however that's not the case here in Fedora.
I found out that Fedora installs the binary at
/usr/libexec/polkit-gnome-authentication-agent-1 (Thank me later). So you can run that command, and then open another terminal to try whether Gnome will ask password now back -
win+Q to open another kitty terminal & type in
If you provide the correct password, it will run the command as root user, and so it will return
root to the terminal ;p
So, now that we know that this polkit for gnome works successfully, we should write it to the hyprland config file to run this command everytime on logging into hyprland. To do so, open
Now, save it and press
win+M to crash/stop Hyprland, which will take you back to GDM login screen. Login back to Hyprland, and open up the terminal and run back
pkexec whoami to find out that the Gnome UI like popup will ask the password back again - which confirms that Hyprland already ran that command which we asked it to.
But, its not over...
If you were already using your favorite browser on Gnome desktop before, I bet you logged into some of the sites. But if you try to open the same browser on Hyprland, you lose all your logged in passwords and such. Wonder why? It's because all those browsers and third party apps dont know what Hyprland environment is, and since they aren't inside gnome environment, they can use gnome password manager to login your online accounts. Wondering what's the solution? I did too. I searched all across the internet, and couldn't find any solution. However, I got a feeling that I should mess with the environment variables to check whether I can fake like as if I was in a Gnome environment - and to my suprise, I had succeeded!
After looking into Hyprland docs back again, I found a small spoiler alert that Hyprland sets up some envs which says to every app that they're in Hyprland environment.
"however it is not a bad idea to set them explicitly" - oh wow... who knew the answer was put up like this?
Since we are using Wayland on both the desktops, we don't need to change the 2nd option. However, we need to set the other two envs to fake the whole environment that we are in Gnome.
Type in this to the
~/.config/hypr/hyprland.conf file, just on top/before any
exec-once statements, so any command ran will have these envs setup already:
env = XDG_CURRENT_DESKTOP,GNOME
env = XDG_SESSION_DESKTOP,gnome
Wondering where did I find these two variables? I just opened the terminal in Gnome desktop and echo'ed it back to me ;)
You can run any applications now, and they will be synced & logged in on both the desktops! Congrats, you have your (soon to be) dream setup! Happy ricing your Hyprland!

As I sit here working on performing some GoldenGate migrations to AWS for a client, I’ve been thinking about the glimpse of GoldenGate Cloud Service (GGCS) that was provided to me earlier this week. That glimpse has helped me define what and how GGCS is going to work within the Oracle Cloud space. Ever since this service was announced back at Oracle Open World 2015, I’ve been wanting to get my hands on this cloud product from Oracle to just better understand it. Hopefully, what I’m about to share with you will provide some insight into what to expect.
First, you will need a cloud account. If you do not have a cloud account; visit http://cloud.oracle.com and sign up for an account. This will typically be the same account you use to login to My Oracle Support (MOS).
Once you have an account and are in the cloud interface, subscribe to some services. You will need a Database Cloud Service or an Compute Cloud Service. These services will be the end points for the GGCS to point to. As part of setting up the compute node, you will need to setup SSH access with a public/private key. Once you create the GGCS instance, the same public/private key should be use to keep everything simple.
Once GGCS is made available for trial, currently it is only available through the sales team, many of us will have the opportunity to play with this. The following screen captures and comments were taken from the interface I had access to while discussing GGCS with Oracle Product Management.
Like any of the other cloud services from Oracle, once you have access to GGCS it will appear in your dashboard as available cloud services. In the figure below, GGCS is listed at the top of the services that I had access to. You will notice over on the right, there is a link called “service console”.
When you click on the service console link, you are taken to the console that is specific to GGCS. On the left hand side of the console, you will see three primary areas. The “overview” area is the important one; it provides you with all the information needed about your GGCS environment. You will see the host and port number, what version of GGCS you are running and the status of your environment.
With the environment up and running, you will want to create a new GGCS instance. This instance is created under your cloud service console. On this screen you are given information that tells you how many instances you have running with the number of OCPUs, Memory and storage for the configuration along with the public IP address. Notice the button to the right, just below Public IPs, this is the button that allows you to create a new GGCS instance. In the figure below, the instance has already been created.
Drilling down into the instance, you are taken to a page that illustrates your application nodes for GGCS. Notice that the GGCS instance actually created a compute node VM to run GoldenGate from.
With everything configured from the Oracle Cloud interface, you can now access the cloud server using the details provided (do not have current screen shots of this). Once you access the cloud server, you will find that Oracle GoldenGate has been configured for you along with a TNS entry that points to a “target” location. These items are standard template items for you to build your GoldenGate environment from. The interesting thing about this configuration is that Oracle is providing a single virtual machine (compute node) that will handle all the apply process to a database (compute node).
With the GGCS service running, you are then ready to build out your GoldenGate environment.
Like many other GoldenGate architectures, you build out the source side of the architecture like anything else. You install the GoldenGate software, build an extract, trail files and a data pump. The data pump process is then pointed to the GoldenGate Cloud Service (GGCS) instance instead of the target instance. The local trail files will be shipped to the GGCS machine. Once on the GGCS instance, the replicat would need to be configured. Part of the configuration of the replicat at this point is updating the TNSNames.ora file to point to the correct “target” compute node/database instance. The below picture illustrates this concept.
You will notice that the GGCS is setup to be an intermediary point in the cloud. This allows you to be flexible with your GoldenGate architecture in the cloud. From a single GGCS service you can run multiple replicats that can point to multiple difference cloud compute nodes; turning your GGCS into a hub that can send data to multiple cloud resources.
In talking with the Oracle Product team about GGCS, the only downside to GGCS right now is that it cannot be used for bi-directional setup or pulling data from the cloud. In essence, this is a uni-direction setup that can help you move from on-premise to cloud with minimal configuration setup needed.
Well, this is my take on GGCS as of right now. Once GGCS trials are available, I’ll try to update this post or add more posts on this topic. Until then, hope you have gain a bit of information this topic and looking forward to using GGCS.
Current Oracle Certs
I’m Bobby Curtis and I’m just your normal average guy who has been working in the technology field for awhile (started when I was 18 with the US Army). The goal of this blog has changed a bit over the years. Initially, it was a general blog where I wrote thoughts down. Then it changed to focus on the Oracle Database, Oracle Enterprise Manager, and eventually Oracle GoldenGate.
If you want to follow me on a more timely manner, I can be followed on twitter at @dbasolved or on LinkedIn under “Bobby Curtis MBA”.

About the Author: P.Sasi Kiran is pursuing B.E. in Mechanical Engineering from ANITS, Visakhapatnam. He was selected for Internshala VTC’s Young Achiever Scholarship and shares his experience with the AutoCAD training.
I registered at Internshala in the hope of finding internships during my 3rd year. One day, I came across the advertisement of ‘Internshala VTC Young Achiever Scholarship’ while browsing on their site. Intrigued, I clicked on the given link and read all the details. Through this scholarship, Internshala was providing free online training to students who were good at academics but were not financially strong. That’s when I realized how much they cared for the students! I applied for that scholarship and, fortunately, got selected. I joined their AutoCAD training program.
To be honest, I didn’t show much interest in the first week of the program. One day, while talking to my brother, who was working in a software company, I mentioned about the program. He advised me to complete the program sincerely as he had seen HR managers giving importance to VTC certification during recruitment. After listening to him, I got motivated and resumed the program again.
As I started the program, my only aim was to get the certificate but after listening to their tutorials I got hooked. They teach the program from the scratch – all the basic tools and concepts are aptly covered. Coming to the program details, it’s clearly divided into different modules. Moreover, you can’t go to the next module until the first module is finished. There is a test at the end of every module which is helpful in checking one’s learning. After completing all the modules, you have to clear a final exam to get the certificate. It is much better than any offline training institute which provides certificates if you just pay the fee; here, a certificate has to be earned – you actually need to learn the skills taught in the program.
I feel the program was very student-friendly as I could access it anytime according to my schedule. Also, the daily live chat facility with the course coordinator was something which I never expected and it really helped in clarifying my doubts.
During the last three days, when I was supposed to take the final exam, I had to leave for another state due to some unforeseen circumstances. After I returned, I was unable to access the program and couldn’t give the exam. I emailed my problem to the support team and asked them to grant me the required access for taking the exam. The following day, I got an email from them wherein they accepted my request and provided the available dates for taking the test.
I sincerely thank Internshala team for providing me this opportunity and supporting me throughout the program.

Root Domain Website Hosting for Amazon S3
As you may already know, you can host your static website on Amazon S3, giving you the ability to sustain any conceivable level of traffic, at a very modest cost, without the need to set up, monitor, scale, or manage any web servers. With static hosting, you pay only for the storage and bandwidth that you actually consume.
S3’s website hosting feature has proven to be very popular with our customers. Today we are adding two new options to give you even more control over the user experience:
- You can now host your website at the root of your domain (e.g. http://mysite.com).
- You can now use redirection rules to redirect website traffic to another domain.
Root Domain Hosting
Your website can now be accessed without specifying the www in the web address. Previously, you needed to use a proxy server to redirect requests for your root domain to your Amazon S3 hosted website. This introduced additional costs, extra work, and another potential point of failure. Now, you can take advantage of S3s high availability and scalability for both www and root domain addresses. In order to do this, you must use Amazon Route 53 to host the DNS data for your domain.
Follow along as I set this up using the AWS Management Console:
- In the Amazon S3 Management Console, create an S3 bucket with the same name as your www subdomain, e.g. www.mysite.com. Go to the tab labeled Static Website Hosting and choose the option labeled Enable website hosting. Specify an index document (I use index.html) and upload all of your website content to this bucket.
- Create another S3 bucket with the name of the root domain, e.g. mysite.com . Go to the tab labeled Static Website Hosting, choose the option labeled Redirect all requests to another host name, and enter the bucket name from step 1:
- In the Amazon Route 53 Management Console, create two records for your domain. Create an A (alias) record in the domain’s DNS hosted zone, mark it as an Alias, then choose the value that corresponds to your root domain name:
Create an Alias (A) record and set the value to the S3 website endpoint for the first bucket (the one starting with www).
We’re also enhancing our website redirection functionality. You can now associate a set of redirection rules to automatically redirect requests. The rules can be used to smooth things over when you make changes to the logical structure of your site. You can also use them to switch a page or a related group of pages from static to dynamic hosting (on EC2 or elsewhere) as your site evolves and your needs change.
Amazon CTO Werner Vogels has already started using root domain support for his blog. Check out his post for more information. Our walkthrough on setting up a static website using Amazon S3, and see the Amazon S3 Developer Guide contains even more information.
If you are looking for some tools to help you build and maintain a static web site, take a look at the Modern Static site.

First thanks from ERPNEXT team , so always add new feature and make it erpnext better . i test Email inbox for 2 day and i have bellow issue , Any one use email in box and have solution for that ?
My login email to erpnext different with email set for email inbox .
1 ) when i forward or reply email , didn’t show in sent folder of Email inbox .
2 ) there isn’t any thing that show sender of email is in contact or lead or address , … for every email show option to add in lead or add in contact , even that email already is in contact .
3 ) i set same email in outlook too ( POP/SMTP ) but after that most of email i didn’t receive any more in outlook .
4 ) there isn’t any option when we received email for request prices , directly quote and reply him .
5 ) there isn’t any option to check if email from current customer/lead / supplier link to his account and check his status .
6 ) some email , ( html) not show well like bellow attachment ,but in outlook show it .
I think that what he means is that when you receive an email from an existing contact, there is now clear reference to that contact and it still shows the “Add contact” option, what doesn’t make sense as it’s already a contact.
One other thing a noticed myself lately is that I’ve received an email from an contact as a reply on an email I’ve send. The status of the contact changes to open, what is correct. I didn’t reply to him in time so he send me a reminder, this reminder (follow up email) was not shown under the contact.
I’m also wondering why the body of the received email (like in the attached screenshot) is displayed in an editable text box. It doesn’t make sense to do this unless your sending (editing) an email, does it?
I think we are trying to do too much with this email inbox right now and while down the road it would be nice to have the option to conduct all business in ERPNext i.e. email also…
I venture a guess that most users will already have a very robust client in play like Outlook or gmail.
I think right now we need to fix the basic email functions that allow current email systems to work with ERPNext, like having split logon for imap and smtp. This was how it was but for some reason was changed with out any documentation or explanation making configuration problematic.
I think that the most important job of a CRM, and I presume the email inbox is an important part of a CRM, is to connect the different communication with contacts an related documents/items so it can be traced back in the future.
One of the most frustrating things I experienced when using a stand alone mail client instead of using an integrated solution, is tracing back all the communications that has been relevant for a certain client, product, project etc.
I hope someone can explain me how to use a external mail client with ERPNext and still be able to trace all communication?
To improve the usability of the Email inbox I would suggest:
Solve the pop and imap errors
Display clearly the contact, and other documents the email is linked to (like the way sales documents are displaying related documents at the top of the form).
Make it possible to links emails to other documents many to many. (it often happens that in one email multiple projects / sales documents / products are discussed)
Only editable body and subject field when your composing an email not when reading.
Be able to group emails belonging to one conversation in a treeview.
Fix the CSS display faults
Be able to make an task, quotation and sales order direct from email.
Be able to easy set an reminder within a certain amount days if there hasn’t be a reply from the contact.
I think that most things shouldn’t be that hard to implement as they already exist for other doctypes, but i could be wrong I’m not an developer after all
Not working for me either, I have tested with my personal POP IMAP Server, and Even with Gmail Server, as @mayar said even I am not able to see the emails.
Apart form that, yes missing css fix is required.
I think the email inbox feature is need to be improve more, and it should act like the email clients, i.e. Thunderbird, Outlook etc, if the imap option is given, it should show the all folders including inbox sent spam other folders.(if I have created any other folder, as a subfolder of inbox).
It should have the separate search box for searching an email.
Good notification system for new incoming email, and if possible the rules for the email.
I’ve just playing around with the email inbox as I’m still wondering if it would be a reasonable option to use on an exclusive email client.
As mentioned by @meisam in his opening post he’s facing the problem that ERPNext doesn’t seem to recognize the sender as a contact (presuming that the email address is already assigned to a contact).
I’m facing this same problem. If I receive an email from an existing contact ERPNext doesn’t seem to recognize and link this. I would suspect that I would be able to find contact details enclosed to the email and more important be able to track this email from the contacts form just as you can with an email you’ve send to the contact.
My question are:
Is this normal behaviour or am I missing something?
Is there any progress on improving/fixing the email inbox?
What would be your workflow when using an external email client like Thunderbird or Outlook?
I do get the inbox well specifically the Opportunity section to be able to correctly map email addresses to contacts. I think this was broken a few months back but working on v9 for me.
In part of the CRM group who also want to work on email handling. Although this was something we discussed I can’t say that anything much has happened so far. Im not a developer so can’t help directly but I have been flagging CRM / email issues in github and raising a few ones that are now fixed.
Although it’s possible to interface with Thunderbird etc it is tricky. I use the Thunderbird redirect add-on to redirect mails I receive into a pickup address for ERPnext. This means that they get logged as Opportunities with the original email sender’s name too. But replying to mails is harder as the reply to headers need to match what ERPNext requires to intercept mails and add to the correct doctype.
Odoo went thru a similar issue. They had some nice Thunderbird and Outlook add-ons to work with Odoo but just found workflow was too clunky to work reliably so these were removed around their v7.
If you wish to help please join the CRM community group as the more the merrier
Thank’s for your reply. Do you mean that if a contact sends you a new email (not a reply), this incoming email is automatically mapped to the contact and shows up in his comments section? This is what I think is normal behavior but I’m unable to get it to work. I’m on version 10.
After some reading around I’m really wondering what the added benefit of the Inbox is as it doesn’t seem to behave as you would expect from an email client?
As for your question to join the CRM group. I think that there already a dozen of topics and Github issues that have good suggestions and pointing out bugs and other problems. To move forward someone has to start coding, as I’m not a programmer I can’t help with that. I’m more than happy to test new things out but that doesn’t bring us forward at this moment

Here's some tools to help you crack Wordle, create your own Wordle, or just find some strategy tips.
Links on this page:
Make your own
Create custom wordle game
Submit a word of your choice to create your custom wordle game
I'll be honest, Wordle is fascinating. It's not only taken the world by storm quite suddenly, but it's actually really good. If you try and tweak the game at all, it doesn't really get any better: the gameplay is really nicely balanced while being simple and relatable.
So I wanted to create a tool to crack Wordle. I don't consider this cheating: it's just how my head works and it's just doing the work for me 😜 On that point though: I'm not advocate of tools or hints that use Wordle answer data to help you. Basically, it's possible to look at the future Wordle answers by looking at the back end code. Some websites have given hints and tips based on what they know the answers will be in the future. If that's what you want, this tool won't help you.
My wordle cracking tools uses raw data and comprehensive algorithm to determine the best possible match, without any knowledge of the future answers, just like most normal users. Here we go:
- It seems obvious to find what letters occur most in a library of 5 letter words, and use the most popular ones first.
- At first this also seems to be a drawback: using the 5 most popular letters means that you're not going to narrow down the results as much as using less popular letters.
- However, in practise this does not seem to be the case. If you use the 5 most popular letters, and 2 are right, 3 are wrong, that often seems to reduce the results from 16,000 words to about 700 words:
- As an example using "arose" as our word, if any 2 letters are right, and we exclude the other 3, we get the following results:
- "ar" results in 786 words. "ao" results in 589 words. "as" results in 1081 words. "ae" results in 971 words. "ro" results in 396 words. "rs" results in 262 words. "re" results in 779 words. "os" results in 692 words. "oe" results in 581 words. "se" results in 918 words.
- It also seems ideal to use a different strategy for each round
- When we begin, we've got very little data to work on. The only thing we know is that the word is 5 letters.
- Initially we have two objectives: it's helpful to target vowels early on, but also useful to target the most commonly occuring consonants.
- So we can at least filter out every word in our database and only include the 5 letter ones. This results in about 16,000 words.
- The algorithm then scores the words in the list in a number of ways. First we count how often each of the 26 letters occur in the entire database. More frequently occuring letters get a higher score.
- We score the word initially by looking at the total score for letters within a word. However we then need to take into account duplicate letter so we halve the score for each set of duplicates.
- We then have a list of all 5 letter words in our database, ordered by score.
- This results in the word "arose" being top of the list, so let's start with that.
- Now for round 2, it depends a little on the results from the previous round.
- If the first word gives us two or more "green" letters, I would put in the results as they are into the tool below, because knowing 2 letters in the right place is a huge jump start.
- HOWEVER, the chances of getting 2 green letters in the first word are approximately 1:160 - not hugely like to happen although possible.
- On the other hand, using a word like "arose" checks out the most popular letters, so it's likely you will have some letters right but not in the right place.
- We could use those letters and try and find words that check out, but as a general rule, you'll be lucky to have less then 5000 matching words after filtering results from your first round. I think we need more data before we do anything else.
- So let's put all the letters of "arose" into the "excluded" field below. We have data on all of these letters but we have 21 more letters to check so let's get some more data.
- After updating results with the removal of the letters "a r o s e" you'll find the next most popular word is "unity". The scoring system will recalculate it's scores based on the filtered results, so words will be freshly scored and sorted.
- 5 new letters to get some data on! Let's enter those and see what results we get now.
- So now we have some data on 10 of the most popular letters in 5 letter words. Data on 40% of our 26 letters is proportionately more useful and accurate then data on 20% of our letters
- Let's update the fields below with our data now. Let's add green letters where we know where they are, yellow letters in the included and grey letters in the excluded column
- Hopefully now you've got a lot less results to choose from. Generally you'll probably end up with 20-100 possible word matches now.
- Now at this point there are a couple of nuances that the algorithm won't take into account. One thing we know is that Wordle uses words that in normal use in the English language. A lot of words we include in our database are "possible" and "valid" matches, but they are unlikely because they are so little known.
- If you flick through the list of your results below, you'll see what I mean: a fair few of the words are probably ones that you didn't even know existed.
- So take a look through the list: do any words jump out at you as being popular or commonly used words? If so, give it a whirl, girl!
- Again, the scoring system will have freshly calculated scores and sorted the words in order of highest score to lowest. However as I say, the algorithm doesn't yet account for word popularity and frequency of use.
- I'll be honest, you had good chances of guessing the right word in round 3: but still only about 1:20 chance so don't feel bad if you haven't got it yet.
- However after entering in results from all 3 previous rounds, you probably have about a 90% chance of getting the word this time. Make 100% sure you've entered all the letters in the correct place, update the form and then check out the top word matches again.
- Anything stand out? One word you know amongst several words that you don't know? You've probably found out the answer 😉
- Enter your best choice and see if you're right!
- Ooh risky stuff! If you still haven't got the word by round 5 and it's not obvious, we'll have to change the strategy for this round.
- Right now, you have 2 chances left. This is deep water. Right now, it's not about finesse or getting a nice score, it's about staying alive, playing dirty, anything just to make 100% sure you win this game.
- With that in mind, this is how we're going to do it: we'll try and use up as many unknown letters in Round 5 as possible. So any green letters you have - keep them out. We know what and where they are: we have all the possible data about them. So there's nothing more to find out, leave them out.
- So for Round 5, enter all the letters you've used so far into the excluded box, clear all the other boxes. You'll likely get zero results. If you do get a valid result, play this word for the round.
- If you don't get a valid result, start by removing some yellow letters from the excluded box, one at a time. As soon as you get a valid result, play this word.
- This is a way to get some data on as many letters as posisble that you haven't yet used. This is the best way to identify the correct word in the last go.
- Right, now then. Update the form completely with all the data so far, double check it to make sure it's all correct.
- It's unlikely you'll have more then 5 words that match now, most likely you'll have 1 or 2.
- Again, let's think about frequently used words, common words that are well known in the English language.
- Choose wisely, this is your last go!
- Boom! Boom Boom Boom! This is what I created this tool for.
- Actually I didn't really. But give me a like or buy me a coffee?
- Link here...
- Even data couldn't save you 🙁
- I'm sorry. I've tried my best. But maybe something went wrong on my side. Maybe my database wasn't complete. Maybe I made a mistake somewhere.
- So if you think there's anything I could do to improve this, you've got a couple of options:
- Submit a missing word that you think I don't have
- Or contact me with some general feedback here

You know, basic python will run well even on 512 MB RAM, but the python with all of its Machine learning environment (Ex: Anaconda) requires 4GB Ram to work smoothly.
If you plan on building a PC solely for gaming and some general, basic, everyday activity, 64 GB of RAM is just too much.
A dedicated graphics card can be used with python and it’s an essential part of the laptop.
Can I Run Python on 2gb Ram
- Originally Asked: Will Python run on 2GB RAM?
- Of course brother, It’ll run smoothly.
- You know, basic python will run well even on 512 MB RAM, but the python with all of its Machine learning environment (Ex: Anaconda) requires 4GB Ram to work smoothly.
- But still, It will run great on 2GB.
Is 32 Gb of Ram Overkill
There are instances where 32GB of RAM is an appropriate amount to have, but this is not always the case. Having 32GB of RAM is also a good way to future-proof your PC as requirements rise over time.
Is Python a Heavy Software
- You will be fine with almost any graphics card.
- One thing you might consider is that you can use GPU for machine learning, so if you plan to go down that path, you could invest in a better graphics card just to be prepared.
- As you probably guessed, Python is not GPU heavy either.
Can a Laptop Run Python
The fact that Python is used on a variety of platforms and operating systems makes it one of the most well-known and widely-used programming languages in the world, but not every laptop can support everything that Python needs.
Does Python Need Graphics Card
- While you might not think a graphics card is necessary, it really can be, depending on what you plan to do on the laptop.
- They can be used for both python programming and gaming, so you need to make sure that’s available.
- A dedicated graphics card can be used with python and it’s an essential part of the laptop.
Is 64 Gb of Ram Overkill
- The amount of RAM you require will ultimately depend on your workload.
- If you plan on building a PC solely for gaming and some general, basic, everyday activity, 64 GB of RAM is just too much.
- 64/128 GB of RAM is overkill for the majority of users.
Is 128gb Ram Overkill
Because RAM is the computer’s ability to store data and keep it there when it needs to run applications, RAM cannot be overkill. If your RAM size is insufficient, the computer will run slowly and may become unresponsive to commands.
Is 2gb Ram Enough for Pycharm
According to the system requirements on the PyCharm website, 1 GB of RAM is what PyCharm suggests.
Can I Run Pycharm With 4gb Ram
PyCharm developers need a computer to have a minimum of 4 GB RAM for PyCharm to work well, even though PyCharm may not be as quick as Visual Studio Code.
Can I Do Coding With 4gb Ram
Yes, of course, you can learn to code with 4GB; however, once you gain experience and start earning money from coding, you should invest in a good computer with more RAM.

fyi, gRPC apparently has a default receiver limit on message size of 4 MB, but we need to set the limit to 20 MB + 1 byte.
@jganetsk @lukesneeringer I've added a commit that brings connection pooling to subscriptions. If one (or both) of you could kindly review it, it would be greatly appreciated!
Doing a review now. :-)

@callmehiphop It looks like there are only a couple action items left from the review. What do you think is the ETA to get them done?
@lukesneeringer I'm aiming for tomorrow.
@lukesneeringer @jganetsk @stephenplusplus I think we're in a good place, PTAL :)
@callmehiphop any chance you could host the docs on your gh-pages?
@stephenplusplus sure can, I pushed the JSON but gh-pages is being slow I think
I think this works: http://callmehiphop.github.io/gcloud-node/#/docs/pubsub/0.14.0/pubsub

@stephenplusplus any ideas why this is happening? Usually that error indicates that a user is running the wrong version of Node with a certain dependency. Testing against 4 seems fine AFAIK, so I'm confused why there'd be a version mismatch with only my PR
I think it could be because you're not rebased off master, and our test script changed.

Nitpick: if I omit the first argument from removeListener (e.g. subscription.removeListener(messageHandler), the resulting error message is "listener" argument must be a function.
Personally, I feel like something along the lines of either This method requires 2 arguments or "listener" argument must not be null would be a more useful message.
Alternatively, we could support the "unspecified event name" syntax, e.g. subscription.removeListener(listener) (as opposed to subscription.removeListener(eventName, listener)).
Thoughts?
@ace-n IMO we should leave the interface as is. We're using Node's built in EventEmitter class and I think if we start modifying the usage or error message details, it could become harder to solve issues that would otherwise be easily solvable through a StackOverflow search.
@stephenplusplus what are your feelings on this?

Yeah, I think we should stick with the native implementation. If we haven't already, we should make it clear we are extending an EventEmitter and link to the official Node.js docs on the subject, https://nodejs.org/api/events.html.
Another question - I noticed we're removing the topic.exists() and subscription.exists() methods.
That functionality is not strictly necessary (it can be duplicated by filtering through getTopics() or getSubscriptions() respectively), but would it be worth keeping?
Another question - I noticed we're removing the topic.exists() and subscription.exists() methods.
Hey good point! Those methods were generated by our internal code so I missed them. I'll add a commit to bring them back.
@stephenplusplus I just realized that moving to gax will also make get and the autoCreate option disappear. Have we implemented those in other APIs? Or is that something we are moving away from?
It would be cool to get that into GAX (see https://github.com/googleapis/gax-nodejs/issues/71), but until then, we have to keep it here.

Plugin works heavily inconsistently
Describe the bug
Plugin works inconsistently - works fine on some languages or partly at others (i.e. only curly brackets colored)
Steps to reproduce
Absolute barebones setup - 3 plugins (packer.nvim, nvim-treesitter, nvim-ts-rainbow), absolute barebones config (enabled highlight and rainbow), no colorscheme, no other configurations whatsoever
Expected behavior
Colored brackets on something like {{{{{{}}}}}}, [[[]]], ((()))
Screenshots
It actually sometimes changes when disabling TS' highlight (in this case square brackets changed a bit)
Rust, for example, works perfectly fine (although notice that deepest pair of round brackets are blue instead of purple)
YAML doesn't work at all
Lua work partly
:checkhealth is fine, I also tried reinstalling treesitter completely...
NVIM v0.6.0-dev+324-ge8fb0728e
I am at loss about why it doesn't work honestly
Is the ((())) syntax valid? Do you see errors in the playground (nvim-treesitter-playground)? Does it also happen when you write normal stuff like foo(bar(lorem(ipsum)))
Bash: {{{}}} is a valid expression, no errors in playground, broken highlight. echo {{{}}} is a valid expression too, once again no errors and this time brackets are completely white.
((())) is not valid, there is an error, highlight broken
${arr[]} I find this example interesting - it is valid syntax and will fail only in runtime, no errors, broken highlight (first square bracket is highlighted, second is not). If you nest this expression (array[array[array[array[]]]]), highlight will break at all
if [[ ... ]] expressions are broken too:
Rust: valid everything, compiles and runs
YAML: All three (((())), [[[]]], {{{}}}) are valid syntax, plain white
Lua: ((())) is not a valid syntax, however errors from playground, normal chains (foo(bar(baz()))) work fine; [[[]]] isn't either, playground throws an error. {{{}}} is valid.
Python: everything works
👍
Small update - Bash's if [[ ]] (empty expression) is not valid syntax, although playground gives no errors; if it's not empty - it works.
It also seems like it doesn't work inside Lua blocks inside Vim files
Did you install the vimscript parser and enable languagetree?
Noted, thanks
@optimizasean can you share your config?
In case of ${arr[]} example wrong highlight may or may not be relevant to overlap (Please do note that I do not know anything about treesitter or plugin and this is pure speculation)
Here is, however, working example with no runtime errors and no parsing errors:
Other languages work good enough, although I am really curious about why those little things are happening with no treesitter parsing errors
(this explains the wrong colour, both the cyan brackets in my screenshot are inside equally many nodes because the ending bracket is left out)
https://github.com/tree-sitter/tree-sitter-bash has open issues like this
In conclusion:
Nested empty expressions are not really used, also if I wanted to make that work then #33 would be more prominent because I only count specific nodes to change color for all the languages in https://github.com/p00f/nvim-ts-rainbow/blob/master/lua/rainbow/levels.lua
Bash - buggy parser
Lua blocks in vimscript: I'll try to fix this
Mentioning this issue here for some people that might see this and stumble into a fix: Issue 71 Configurations unclear - documentation improvements for the new nvim-mers
Also, @p00f my configuration is the same as in the linked issue above #71 (more complicated now that I got rainbow working).
Files must have a recognizeable extension for treesitter to know how to parse them, it must have support for that language, and you must have that language installed and configured (maintained v.s. all in linked issue - can also manually activate and install through TSInstall and TSEnable if I remember right). Then if you open that file with nvim, treesitter builds the tree properly and it should work.
^Notes of why it won't work if you just start a new nvim window = language cannot be recognized. That is a treesitter problem, not necessarily bug here. Also bash is weird but it works now...I think? Not the most advanced bash programmer here so maybe there is a case it doesn't work but I can verify that C# was *definitely working!

This option was introduced in version 188.8.131.52 of Diafaan SMS Server.
Thank you for the quick response 🙂
I have checked the Advanced properties of some of the GSM Modems and I can't see a property called 'PermanentErrorList'. The closest I can find is 'PermitModemCommandMessages'?
We are running version 184.108.40.206, do we need to update?
CMS Error 21 means 'Short message transfer rejected'. It indicates that the mobile service does not accept the message but it does not give the exact reason why. It could be an invalid number, insufficient SMS credits or a number of other reasons. Diafaan SMS Server has no way of knowing if the message also will be rejected by another mobile service before trying it. The reason that the other modem may give a different error code for the same message is that the error is generated by the mobile operator and each operator has its own error handling procedures and might generate a different error code for the same underlying error.
Diafaan SMS Server is designed to route the messages through all designated gateways before giving up because it is also used for alarm applications where it is important that the message is sent even if there is a good chance that the message will be rejected by the next gateway as well. But you can change that behavior by adding a (list of) permanent error code(s) in the 'PermanentErrorList' property in the advanced settings of the GSM Modem Gateway. This makes sure that Diafaan SMS Server does not make further send attempts when this error is returned by the modem.
I was wondering if you could clarify something for me?
We have quite a complicated setup, so I'm going to massively simplify things to home in on the specific point.
You have two sim's, and each simm is for a different provider. Each simm is setup as a GSM Modem.
You have a scripting gateway that calls PostDispatch like so (the first 5 values are obviously variables, the last two values are hard coded)
PostDispatchMessage(recordId, toAddress, fromAddress, strMessage, messageType, "GSM1", "GSM2")
If when sending the message Diafaan recieves a CMS Error 21 (rejected) message from the network it fails over and tries to send the message via the backup gateway.
We have found that in a high percentage of cases the attempt on the backup gateway also fails (albeit with a slightly different error code).
Is this behaviour by design? Should Diafaan be trying to failover to the second gateway when confronted with a CMS 21 error?
Is there any way to change this behaviour?
If there isn't then it would be great if you could define a list of codes that will always fail over, and a list of codes that will never fail over.
Look forward to your response, hope that makes sense!

Yang Song: using natural language processing to study Princeton history
Song majored in Computer Science (COS) and also earned five certificates: the Undergraduate Certificate Program in Statistics and Machine Learning from the Center for Statistics and Machine Learning (CSML), Applied and Computational Mathematics, Engineering and Management Systems, Finance, and Music Performance in Clarinet.
Song became interested in Princeton history when he learned that the University library had digitized issues of the Daily Princetonian stretching back to the late 1800s.
“The digital archive is amazing because it allows historians and researchers to easily access the issues. It is also important because some of the old newsprint has become very fragile,” he said. “The digitalization process was incredibly manual and work-intensive, with entire copies of old newspapers on microfilm sent to Canada and Cambodia to be photographed. The content was then extracted using optical character recognition.”
For his independent project for the CSML certificate, which he undertook in the fall of 2018, Song decided to analyze the content of the Daily Princetonian from 1946 to 2015 using machine learning algorithms to perform natural language processing.
Specifically, Song stated in his report that his project was focused on “quantitatively analyzing the text within articles to examine Princeton’s history through a linguistic lens. Using several word embedding models including Word2Vec, this project explores the relationships between words, capturing word similarity and association, as well as the change in usage of words over time.”
His work, done under Professor of Computer Science Brian Kernighan as his advisor, builds upon earlier computational work analyzing the Daily Princetonian.
Song tracked the use of certain words over time and made connections between events on campus and the world, such as the admittance of women into Princeton, protests against the Vietnam War, changes to eating club admissions, and the relationship between different residential colleges.
For example, Song saw changes in how people of Asian descent were described, from at first being called Orientals and later as simply Asian. In the past, Princeton students were called boys and girls but are now called men and women. He also saw how the phrase “computer science” grew with popularity over time, eclipsing words like “chemistry” and “mathematics.”
“You can visualize how things have changed over time linguistically and on socio-cultural subjects,” he said.
During the course of his studies, Song found that his CSML classes complimented his computer science courses.
“My CSML classes have been very helpful and they have been a highlight of my Princeton experience,” Song said. “What I learned in my COS classes was theory and I got to apply theory into real world problems and data sets in my CSML classes. I used tools I learned in CSML to achieve meaningful objectives and they also allowed me to delve into different subjects such as economics and math.”
After graduation, Song started work as a quantitative researcher at Citadel, a Chicago-based hedge fund firm. From there, Song plans on exploring the intersection of finance and technology and may enroll in graduate school in the future but is currently leaning to staying in industry.
Song played Principal Clarinet in the Princeton University Orchestra, where he also served as President and Publicity Chair. He also played in smaller groups such as the University Chamber Orchestra and the Triangle Club Pit Orchestra. His highlights include leading the Orchestra to sold-out concerts in Europe and playing under Gustavo Dudamel in celebration of the 125th anniversary of Princeton University Concerts. In addition, he was a teaching assistant for the Computer Science Department, lead E-Quad tour guide, dormitory assistant, and peer career advisor.
Song listens to music for fun and also plays the saxophone and violin. He also enjoys learning programming languages and solving puzzles, which was inspired by his experience at the International Mathematical Olympiad, winning bronze and silver medals representing Australia. In his spare time, he enjoys cycling along the Chicago lake.

So I've wanted to learn some hardware programming for quite a while, and have now taken the first step!
A popular choice of learning resources is the company microchip.com , they have a product called the picKit 2, which is a 'demo board' . After much reading i understand that this is a circuit designed to help you get up and running quickly.
In the case of the pickit2, this means it has a processor on board ( the pic16f917 ) , a bunch of led's already wired in , a potentiometer (turny switch) and a button.. as well as a bunch of open outputs for you to do whatever you like with.
This is not something for the faint of heart it would appear, so after stumbling around the documentation and sample code for a while, i bought this book The Pic Microcontroller, your personal introductory course, a promising name.
The book is very well written, and after the first 2 chapters i felt much more able to approach my board.
The demo board comes with a usb device that attaches it to the computer, i've learned that this is a 'programmer' , which is in charge of delivering the compiled code to the chip itself, the integration of this is one of the things that makes this a 'demo' board.
After some more reading, i tried out my first program, borrowing some sample code from one of the existing projects, I had success!
See here my first program running, in all it's glorious 7 lights on, 1 light off glory!
Functionally, every 8 outputs get assigned a file register (memory location), and by assigning an 8 bit binary value to this location, you can set the pins as either on, or off. So to set the first pin on, you use a value of 00000001 , the first and last as 10000001, etc... The default numbering system in assembly is hexidecimal, so you represent these as hex, so, 00000001 = 1, 10000001 = 81.
MainLoop movlw 0xfd movwf PORTD
so, as you can see here I am using the hex value fd, and assigning it to the file page that controls my led's. fd of course equals 253 in decimal, or 11111101 in binary, so you can see the led that's off. The other commands are pretty simple as well mov = mov l = literal w = working register (you only get one of these, everything moves through it) f = file page
so movlw 0xfd means, move a literal into the working register, and then i give the literal 0xfd , 0x just means its a hex number. I could aslo have used movlw b'11111101 , or for that matter movlw d'253
and then movwf PORTD means, move the working register into the filepage PORTD (my output register).
Really pretty simple at the end of the day, once your environment is running.

It's all empty, but my project actually has 24g
I think it didnt scanned properly. Can you check if there is any error messages in OutputLog ?
Look into the folder "Saved", you can delete it safely.
Hi! I just downloaded this plugin and started exploring the plugin. I'm encountering the same issue as reported here. It shows my directory structure, but everything is just 0.
I've noticed when the plugin starts up, it makes an attempt to fixup all redirectors and a small number of files are checked out. Is having totally clean redirectors a requirement for seeing all the correct data?
We're on a custom version of 5.4 and I installed the 5.4 version of the plugin. Once the editor loads, I just click on the little trashcan icon.
You should do a fixup redirection from de content and look the Output log to see what asset give you error and delete it manually.El 16 dic 2024 23:31, morness @.***> escribió:

Hello @morness
Yes, fixing up redirectors is mandatory before any cleanup operation. Even engine recommend you to perform this operation after moving/renaming assets, but most of the time artists and developers are forgetting to do so and later you will have some real problems. So in plugin I tried to automate this process.
Regarding 0 size, honestly I couldnt reproduce this issue, but maybe its because you using custom engine version, and if you altered some engine code its possible that it might not work correctly. I tested only on original epic versions. Also if you have 0 stats when engine loads, its ok its just means you just need to click "Scan Project" button one more time, engine just cached tab data when you closed editor with ProjectCleaner tab opened.

@AngelAvellaneda glad to be helpful :)
Yep got it working. There were some challenging redirectors to fix. Our company has some P4 checkin policies. Some of the assets that were problematic were collections. The engine attempts to auto submit those on save (there's an editor config for that), but even turning that off, there are situations where the engine still tries to auto submit them anyways, and when it fails, it reverts the CL. So I temporarily modified the engine to not do that and got through those. Tool looks amazing!
I used version 5.1.1, also got the 0 error, I looked at the log and manually fixed the log showing the error of the redirector, but finally there is still an error, in the picture, the log shows the error, but I can not find the corresponding redirector. In addition, I would like to ask what is the meaning of what Could not be deleted in the log

Hello @Not4coding
Could not delete message actually pops when engine tries to fixup redirectors and failed to do so. But is not like regular redirectors that you can see via ContentBrowser filters its more like leftover redirectors . Why they are arise I cant say for sure, but i notice this happens when you migrating project to newer version without fixing up redirectors in old version. Thats one possibility there maybe other reasons i am not aware.
I actually looked in source code of engine there is this part in Engine/Source/Editor/UnrealEd/Private/ObjectTools.cpp
on line 2824 in function DeleteObjects
if ( !DeleteModel->DoDelete() )
{
UE_LOG(LogUObjectGlobals, Warning, TEXT("Could not delete"));
//@todo ndarnell explain why the delete failed? Maybe we should show the delete UI
// when this fails?
}
return DeleteModel->GetDeletedObjectCount();
As you can see there is some TODO that engine developers didnt fix and that is what causing that message to pop and later causing this issues. I reported this problem long time ago when i was using v4.23 if i am correct, but seems they ignoring this problem, because its still exists in 5.5 version :(
In your case i guess you can try to rename as @AngelAvellaneda suggested or duplicate asset and delete old asset by replacing references with newly duplicated asset and then fixup redirectors.
Here is short video on how I do it.
Redirectors Fix
I checked the video you posted, and the issue was resolved after several saves and restarts. Really appreciate your help, thank you. You are my savior. I did migrate project from 5.1.0 to 5.1.1
@Not4coding No problem. Happy to help :)

I updated the scheduler to 2.1 today.
I have structured my decks in decks and subdecks, setting the max new cards and max reviews per day in the parent deck to 999 so that I can learn the cards from 3 decks at once but have them in diffrent decks .
With the update, it shows me the reviews from the subdecks in the parent deck like shown in the picture below.
In the update logs it says this:
When a deck has children, reviews are taken from all children decks at once, instead of showing each deck’s review cards one by one. The review limit of the child decks is ignored - only the limit of the deck you clicked on applies.
I understand that the number comes from this change, but what does it mean that “only the limit of the deck you clicked on applies.”?
Can I have my old status back somehow?
edit: I found this question now: Hide all cards in subdeck with new scheduler
But there was also no solution provided.
Does anybody can think of any kind of workaround to have the old thing back?
If the parent has a limit of 999 and the child of 0, you will still see cards from the child if you click on the parent.
Well, there is. You have to move the subdeck out of the parent deck.
That depends on your setup. I assume you have cards in the “Chess” deck and only want to study those? Then I would move all cards out of “Chess” into a new subdeck called “Chess::Chess” or “Chess::General”. Then you can study this subdeck only.
No sry I wasn’t clear about that.
I have no cards in the parent deck but want to study all the cards in the subdecks in one session.
For example I have reviews in the Chess_Feldfarben and the Chess_reddot subdecks which I want to study in one session.
But in the Chess_100-endgames… deck there are reviews I dont want to study and I want to exclude by setting the max reviews
in this deck to 0.
With the old scheduler this worked perfectly fine, but now all the reviews from all the decks are appearing in the parent deck.
The 34 reviews u see in the pictures are reviews from the 100-endgames deck, which are not appearing directly in the deck, but in the parent deck.
Thx for the answer
This seems like the same issue/change I describe here (though I am using the v3 scheduler the v2 scheduler has the save difference form v1 as I understand it):
A workaround suggested to me was to use tags instead of sub decks but I don’t think that would work for your case of wanting one deck set to 0 reviews.
The only solution I can see at this time would be to downgrade to the v1 scheduler and I’m not even sure that is possible/easy to do unless you have a backup of your profile from before upgrading.

Bintris is a mobile game developed in Go!
Support me by buying this game on Google PlayStore
Or you can of course build it from source yourself (see instructions below
About The Game
Bintris is a small game inspired by Tetris. The goal is to flip the bits so that the bits represent the decimal number in the right column. When the bits represent the decimal number the line is cleared and points are gathered. Number of bits representing the decimal number is also how much points scored for the particular line.
Demo On Youtube
About The Implementation
The game is developed in Go and is implemented using OpenGL (graphics) and OpenAL (sound). Gomobile is used to generate shared libraries that are used for the Android build. The game works just as good on Linux as on Android.
It all started as an experiment with Gomobile and ended up as a fully working game, after a lot of frustration and gotchas! ;) With that said, the source is a bit of a mess and I have some stuff on my todo-list such as implementing full parsing of wav header, a simple FSM for the game etc.
Building From Source
To just run the game on Linux, just issue the commands:
# First remove line for modified version of gomobile sed -i '/nergal/d' go.mod # Then run the game go run .
Build For Android
First make sure you have built OpenAL (
make openal). It's a bit complicated to make the OpenAL build work succesfully with current state of
gomobile. I've added some notes below about this.
Build For Android Studio
The repository includes a very small Android Studio project that is used to build AAB package format for Google PlayStore. This project handles AAB packaging and uses the shared objects (.so) files from the build.
To build/run via Android Studio (make sure to have OpenAL libraries first
make openal, see requirements below):
- Open the project in Android Studio
- Attach mobile or virtual device and run.
Update toolchain.cmake to use
-O3 -s to build smaller version of OpenAL (otherwise you will end up with ~30MB debug none stripped version) Also update to armv8 (line 578) in the toolchain from v7.
Using AAB packaging for PlayStore requires libraries loaded with
dlopen to not use the path. Hence, the audio/al packages requires to just use
dlopen("libopenal.so"). The base.apk in aab doesn't include the libraries rather they are included in the
AL/openal.h etc requires to be in audio/al package dir for rebuilding:
// All other code for reading ENV can be removed. *handle = dlopen("libopenal.so", RTLD_LAZY);
Use `ldflags="-w" to remove debug information from the build (see Makefile)
Changes Required to Gomobile Command
Line 182 in
cmd := exec.Command(cmake, "-S", initOpenAL, "-DANDROID_PLATFORM=23", "-B", buildDir, "-DCMAKE_TOOLCHAIN_FILE="+ndkRoot+"/build/cmake/android.toolchain.cmake", "-DANDROID_HOST_TAG="+t.ClangPrefix())
View logs from connected phone (developer mode):
adb shell pm list packages -f |grep bintris
Too see what is included in the divided apk's.

The family of AAA protocols, which stands for Authentication, Authorization and Accounting, were originally designed as remote access control mechanisms and network service providers through modem and dial-in services, but they continue to be presently implemented in multiple architectures.
RADIUS, which stands for Remote Authentication Dial-In User Service, is the paradigm of AAA protocol. Created in 1991 and originally developed by Livingston Enterprises for the PortMaster series of its Network Access Servers (NAS), it later converted into RFC standards through the Internet Engineering Task Force IETF:
- 1991-1993: Merit Network and Livingston Enterprise (access to NSFnetwork)
- 1997 - January: RFC 2058 (Authentication and Authorization) and RFC 2059 (Accounting)
- 1997 - April: RFC 2138 (Authentication and Authorization) and RFC 2139 (Accounting)
- 2000 - June: RFC 2865 (Authentication and Authorization) and RFC 2866 (Accounting)
Description of a basic AAA platform with RADIUS
Without going into too much detail, we will use RADIUS as an example to describe a typical AAA architecture such as those used by an internet provider or ISP. An intermediate element exists in these types of architectures, the Network Access Server, which operates like a RADIUS client. The client is responsible for sending the user’s information to the RADIUS servers and then acting upon the response that is returned.
The RADIUS servers receive the client’s request and execute the authentication of the user based on the received data (generally against directory servers), returning the configuration with the necessary information so that the client can access the authenticated user service. During this Authentication and Authorization process the user’s validity and the resources it has authorized access to are verified. This procedure is complemented by the Accounting process which registers the session’s relevant data and which is normally used to generate rate-setting registrations.
Authentication and Authorization
The user requesting access makes the request by sending his user information and password to a NAS, who he established a link level point to point communication (PPP). The NAS, which acts as a RADIUS client resends the request to the RADIUS server. This request includes the end user’s information along with his password, which is encrypted with a password that is shared with the server (Authenticator). The server validates the Authentication through any of the supported mechanisms: PAP, CHAP, EAP (challenge-response based mechanisms), Unix login, LDAP, etc. and obtains the relevant information related to the client. If the RADIUS server authorizes the access, it sends a message (Access Accept) with a series of parameters attached that characterize the connection such as the IP address and bandwidth. If the access is rejected, the Authentication/Authorization will be denied, informing the user with an Access Reject message which indicates the reasons behind the rejection.
-Message flow in a RADIUS Authentication/Authorization process -
In addition, once he has been authenticated and authorized, the client can send an Accounting request to start a session which the RADIUS server responds to, initiating a connection registration with data about the start/end of the session, volume of transferred data, etc. The session ends with a request from the server or client (Accounting Stop).
RADIUS’s most common messages
RADIUS has the following messages at its disposal to control all of the phases in the AAA process:
- Access-Request. Sent by a RADIUS client to request access Authentication and Authorization to a network.
- Access-Accept. Sent by the RADIUS server in response to an Access-Request message. This message notifies the client of his Authentication and Authorization which he corresponds to by contributing the necessary attributes.
- Access-Reject. Sent by the RADIUS server in response to an Access-Request message. This message informs the client that his request has been rejected, explaining the reason why.
- Access-Challenge. Sent by the RADIUS server in response to the Access-Request message. This message is sent to the client with a challenge that the client must respond to.
- Accounting-Request. Sent by a RADIUS client to specify information about the connection that has been accepted. It can be start or stop type to start or stop the accounting.
- Accounting-Response. Sent by the RADIUS server in response to an Accounting-Request message. This message notifies about the correct reception of the request and starts the session’s process.
Security in RADIUS.
RADIUS suffers from a number of weaknesses, which are:
- RADIUS messages are not encrypted, except for especially sensitive data such as passwords.
- RADIUS uses MD5 as a cryptographic hash algorithm which means it is vulnerable to collision attacks.
- Communications are performed through the UDP protocol, which means that the IP addresses can be easily falsified and are susceptible to identity theft.
- The specifications for the shared password are not sufficiently robust and are re-used by the server with clients. Therefore, it is vulnerable to brute force attacks. Once the password is obtained, the "Authenticator" field used in Authentication messages (Access-Request) is easily generated.
Some counter-measures which could be used to strengthen RADIUS’s security include contemplating the implementation of IPSec to cipher the communications between client and server. In addition or alternatively, the Authentication can be strengthened by using robust challenge-response protocols such as CHAP.
Evolution of RADIUS.
To solve many of the weaknesses that RADIUS presents as a AAA protocol, DIAMETER, which is an evolution of RADIUS (people said it was "twice as good" and that is how it got its name), appears on the scene and includes the following upgrades:
- It uses reliable transport protocols (TCP o SCTP)
- It uses transport level security (IPSEC o TLS)
- It has a larger address space for attributes (Attribute Value Pairs) and identifiers (32 bits instead of 8)
- It is a peer to peer protocol instead of client-server. Therefore any node can start an exchange of messages.

Twisted 16.5 Release Announcement
Amber "Hawkie" Brown
hawkowl at atleastfornow.net
Sat Oct 29 02:33:57 EDT 2016
On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.5!
The highlights of this release are:
- Deferred.addTimeout, for timing out your Deferreds! (contributed by cyli, reviews by adiroiban, theisencouple, manishtomar, markrwilliams)
- yield from support for Deferreds, in functions wrapped with twisted.internet.defer.ensureDeferred. This will work in Python 3.4, unlike async/await which is 3.5+ (contributed by hawkowl, reviews by markrwilliams, lukasa).
- The new asyncio interop reactor, which allows Twisted to run on top of the asyncio event loop. This doesn't include any Deferred-Future interop, but stay tuned! (contributed by itamar and hawkowl, reviews by rodrigc, markrwilliams)
- twisted.internet.cfreactor is now supported on Python 2.7 and Python 3.5+! This is useful for writing pyobjc or Toga applications. (contributed by hawkowl, reviews by glyph, markrwilliams)
- twisted.python.constants has been split out into constantly on PyPI, and likewise with twisted.python.versions going into the PyPI package incremental. Twisted now uses these external packages, which will be shared with other projects (like Klein). (contributed by hawkowl, reviews by glyph, markrwilliams)
- Many new Python 3 modules, including twisted.pair, twisted.python.zippath, twisted.spread.pb, and more parts of Conch! (contributed by rodrigc, hawkowl, glyph, berdario, & others, reviews by acabhishek942, rodrigc, & others)
- Many bug fixes and cleanups!
- 260+ closed tickets overall.
For more information, check the NEWS file (link provided below).
You can find the downloads at <https://pypi.python.org/pypi/Twisted <https://pypi.python.org/pypi/Twisted>> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads <http://twistedmatrix.com/trac/wiki/Downloads>>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-16.5.0/NEWS <https://github.com/twisted/twisted/blob/twisted-16.5.0/NEWS>>.
Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted!
Amber Brown (HawkOwl)
PS: I wrote a blog post about Twisted's progress in 2016! https://atleastfornow.net/blog/marching-ever-forward/

Passing array in function
I have an array that is read like this:
MyArray(0)='test'
MyArray(1)='test2'
MyArray(2)='test3'
How do I pass this through a function?
Function(MyArray(all_arrays))
What do I put for all_arrays?
MyArray(0)='test'
MyArray(1)='test2
MyArray(2)='test3'
AcceptArray MyArray
Private Function AcceptArray(myArray())
'Code here
End Function
You look to want to pass a string before the array.
So, change the Function to :
Private Function AcceptArray(param1, myArray)
'Code here
'Don't forget to return value of string type.
End Function
And you call this function like this:
returnValue = AcceptArray("MyString", MyArray)
If you do not need to return a value you should use a Sub.
When i pass function ('test', MyArray() as String) i get an error
You use it with : AcceptArray MyArray. If you want to pass other parameter you need to add it. I'll update my answer.
sorry, i dont understand, it wont let me put As String there.. it causes an error.
The reference I found online has: Private Function AcceptArray(byval param1, byref myArray) try something like this out
I modified the snippet of code because I though you were coding in vb6 no in vbscript. You do not have to put the type of the variable with AS statement.
Looks like you need to define you function as such:
Function <FunctionName>(byref <list Name>)
then when you call it in your code use
<FunctionName>(MyArray)
found here:
http://www.herongyang.com/VBScript/Function-Procedure-Pass-Array-as-Argument.html
passing by referrence using just the array name allows you to pass in the entire array to the function
Im much more familiar with VB.net but the source I found looks simmilar enough. hope this helps
what if the function has other values?
function( 'test' , MyArray() ) ?
just change the function definition accordingly. then call it in your code the same way. define it as (byval str, bref alist) and then when you call it use ('test', MyArray)
A simple example...
Dim MyArray(2)
MyArray(0) = "Test"
MyArray(1) = "Test2"
MyArray(2) = "Test3"
ProcessArray MyArray
' -------------------------------------
' ProcessArray
' -------------------------------------
Sub ProcessArray(ArrayToProcess())
For i = 0 To 2
WScript.Echo ArrayToProcess(i)
Next
End Sub
Function parameters can not contain parenthesis. Arrays are passed as normal variables without ().
@AutomatedChaos Thanks for the downvote...but you're wrong. Did you actually try the code? I slightly modified it to make it easier for you to test (DIMmed the array and added a loop to print the values).
Furthermore, the accepted answer is virtually identical to mine, but you didn't downvote it?
I didn't test you code. Now I did and it is actually working code so I corrected the downvote. But you shouldn't use parenthesis inside function parameters; they are not necessary and it is confusing. In VBScript you can practically use parenthesis everywhere, but that doesn't mean you should. And you are right about the accepted answer, I should have threated it the same (I am not on a personal crusade, just wanted to do some quality stuff here).
@AutomatedChaos I appreciate you changing your vote and I'm sorry I seemed so defensive. You are correct that the () are not required, but I can find nothing that indicates you should not use them in this manner. The only reference to it that I could find is on the Sub Statement reference page. Even that page isn't clear. I could interpret it as use () when the argument is an array or the () is optional. I kind of like using them because it is a reminder that you're passing an array.

What makes someone a good designer?
…and other questions I received while speaking on a Women in Tech panel in Seattle, Washington
Last week I had the honor and opportunity to speak on a panel at University of Washington’s Women in UX conference, joined by fellow designers from Facebook and Splunk. There were lots of great questions from both the student moderator and (mostly undergrad) attendees— here are a few highlights.
What makes someone a good UX designer?
I love this question because 1) it came from a new designer on my team who was there to support me and 2) just by asking it, you are well on your way. My answer is simple: a good UX designer asks questions. What if…? What happens when…? How does …? As designers we have a unique opportunity to represent the users (sometimes, we are the only ones on the product team pushing for what is in their best interest), so asking questions is the key to ensuring everyone has a shared understanding of the goals (and non-goals) of the team, the product, the business, etc. In my experience, no question is too basic — bring your beginner’s mindset and don’t be shy about asking the most basic, foundational questions about the concepts, nouns, verbs, patterns, risks, users, behaviors and decisions happening in the product. When you think you’re done asking questions, follow up with a few rounds of “Why…?”. Occasionally in a design review or strategy meeting months into a project I’ll still toss out a “Who is our MVP user?” — when the PMs, EMs or designers all give different answers, its a reminder that no matter how deep into a project we are, its always a good idea to cross check our assumptions. Being a good designer starts with understanding the problem you are trying to solve.
What would you tell yourself while you were an undergrad?
Something I am still working on everyday is not letting the idea of perfection block progress. Much like with my current gig as a product designer, sometimes getting something out the door is more important than making sure is perfect. I would tell myself not to be afraid to fail, to enjoy the process and take bigger risks (everyone on the panel agreed, being a student is likely the only time you’ll have such freedom, so enjoy it!). Also, make connections — the relationships you make in school is where and how you start to grow your professional network. It is a small world and you’ll be surprised at how often you’ll run into a familiar face in the work place.
How might students or women with little experience create a portfolio? Are student projects ok?
I have been a hiring manager (and/or closely involved in portfolio reviews) and depending on the specifics of the position details (if we’re in need of a junior vs. senior designer, for example), I am looking to see if your portfolio demonstrates your design thinking. Do you go deep into solving the problem? What types of constraints did you consider? Student and personal projects are a great opportunity to showcase your personality and passions (I still include a few just-for-fun projects on my own site!), and at the end of the day I am looking for a body of work that stands out from the crowd: a great representation of who you are and how you work. If we meet in person, I might ask you what V2 of your design might look like or how you might iterate on a particular UI. Where you created the project doesn’t always matter — I want to see how you do it.
What do you do outside of work to stay inspired?
I’ve written about my love for artsing and crafting as my own way to unplug and stay inspired, and all three of us on the panel reiterated the importance of finding things outside of work that make you happy.
I’m not sure what facet of UX I want to do. What should I major in?
This was a scary moment — please don’t pick your major based on what I have to say! But I can say this: 2 out of 3 of us on the panel did not go to school for design (I was the outlier) which proves that your coursework doesn’t have to dictate your future. So, find something you are passionate about and give it your all. The beautiful thing about working in any design discipline is that you are building your own, personal toolbox of skills. If you focus on content design and later decide you want to specialize in interaction, your work as a content designer is absolutely relevant and useful. If you start in research and move to information architecture, you will already understand things from the mind of a user. As creative professionals, we are lucky to love what we do, and I truly believe that you will find success if you follow your passion. So, jump into a facet of design that excites you — the passion and energy you bring to work that you are excited about will make it easy to feel if it is right for you (and if it turns out it isn’t, it’s never too late to make a change).
What tools should I learn?
You’ll need some hard skills to work as a designer — luckily, most places are a Choose Your Own Adventure kind of set up. Personally, my team uses Sketch and Invision (same for the other gals on the panel from Facebook and Splunk). Friends of mine are Adobe loyalists paired with Axure or Proto.io. Watching a few Skillshare or Lynda courses on any of the above would probably serve you well. If visual design is your thing, consider taking some foundational art courses to familiarize yourself with basic principles of color and composition. I’d get a sketchbook and practice putting your ideas to paper (check out my #wireframeoftheday on Twitter for examples of quick sketches that conceptualize some UX iterations I’m working on). It is also and interesting exercise to grow your awareness of apps or websites you love — why do you love them? Is it the typography and photography style? Is it a delightful interaction? Once you have a designer’s eyes you will start to notice and appreciate thoughtful details (warning: you’ll also notice all of the terrible, horrible, no-good UX out there too, but you should consider that as opportunities to change the world!).
I also spoke briefly about getting out of your comfort zone (I forget which question triggered this topic) but the idea of pushing past the boundaries of where you are currently as a way to stay inspired, to learn, and to grow seemed to resonate with everyone on the panel. I set a personal goal for 2017 to speak at a conference for the very first time, so when the opportunity to sit on this panel arose I teetered on the fence a bit before committing — mostly because it was intimidating, something I had never done before, would be some extra work on my end, etc. Turns out, is something I want to do more of, but I would have never found that out unless I went for it.
So, to the smart gal in the back who asked me what piece of advice I would give to someone looking to start their careers in design? Go for it.

Dropped response bodies when using Envoy as an HTTP CONNECT proxy
Description:
I'm using Envoy as an HTTP CONNECT proxy, and observing dropped response bodies. This happens non-deterministically - sometimes the client gets the response payload, sometimes it doesn't.
Specifically, Envoy seems to be associating the response payload from the upstream server with the HTTP response it initially sends back to the client as part of the CONNECT protocol.
RFC 7231, section 4.3.6 has this to say about what this should happen:
Any 2xx (Successful) response indicates that the sender (and all
inbound proxies) will switch to tunnel mode immediately after the
blank line that concludes the successful response's header section;
data received after that blank line is from the server identified by
the request-target.
The HTTP response should not contain anything after the blank line following the headers. I'm observing cases where it does.
Repro steps:
Using the following config:

I'm running the proxy in a container bound to the host network (have also tried outside a container, and I see the same thing):
$ docker run --rm -it \
--network host \
-v $(pwd)/envoy.yaml:/etc/envoy/config.yaml \
envoyproxy/envoy-dev:latest -c /etc/envoy/config.yaml
Set up a simple server that prints a message on session establishment:
$ while true; do echo 'hello, world' | nc -l 1234; done
Simulate an HTTP CONNECT from a client:
$ printf 'CONNECT localhost:1234 HTTP/1.1\nHost: localhost:1234\n\n' | nc -w1 localhost 8080
Observe the response traffic from Envoy in tcpdump / wireshark.
Case a) (unexpected behavior) - proxy returns a 200 to the client along with the response payload from the upstream.
Frame 402:
Case b) (expected behavior) - proxy returns a 200 to the client without a body, followed by a packet containing the response payload from the upstream (i.e. payload is not part of the "HTTP body").
Frame 904:
Frame 906:
Repeatedly issuing requests causes instances of both - there is no discernible pattern that I could tell.

cc @alyssawilk. I'm guessing any issue with timing depending on when the data from upstream arrives. Thanks for the detailed report!
Sorry, reading through this I want to make sure I understand the problem
Is the problem that you want
[envoy headers]
[helloworld payload]
in separate packets and sometimes you get
sometimes you get
[envoy headers][helloworld payload]
in one packet?
If so, I don't think that's illegal. I think anything after the \r\n\r\n headers is payload content regardless of it lands in the same packet or not.
Is the problem that you want
Hey @alyssawilk - yeah, that's right.
If so, I don't think that's illegal. I think anything after the \r\n\r\n headers is payload content regardless of it lands in the same packet or not.
Agreed on the semantics there.
The reproducer I mentioned was more to show the TCP framing differences (two packets in the response vs. one, as you mention). My true setup is a little more complex:
client -> Go client -> Envoy (CONNECT passthrough) -> Envoy (CONNECT termination) -> upstream
Based on the framing, I realized the issue is in the Go net package, which doesn't really support CONNECT all that well, and is gobbling up the response body in the case of a single frame. Checking for a body and writing it back to the network fixed my issue.
Closing this, as Envoy isn't really the issue here :smile:
Thanks!
For anyone that comes across this in the future by way of Go / HTTP, here are some relevant links / advice:
do *http.Request.Write it to a self-dialed net.Conn, rather than using *http.Transport.

I’m Daniel Marin, I work at Nexus Labs and was formerly a cryptography student at Stanford.
We are pleased to introduce Nexus to the Ethereum community, a decentralized cloud computing network designed to scale Ethereum’s compute, storage and I/O capabilities. Nexus is an attempt to build a general-purpose platform for verifiable cloud computing, using zero-knowledge proofs, multi-party computation and state-machine-replication.
In particular, we are building:
- Nexus Zero: A decentralized verifiable cloud computing network powered by zero-knowledge proofs and a general-purpose zkVM.
- Nexus: A decentralized verifiable cloud computing network powered by multi-party computation, state-machine-replication and a general-purpose WASM VM.
In the Ethereum context, Nexus essentially functions as a serverless off-chain cloud computing network (similar to Google Cloud / AWS Lambda) that uses MPC/SMR and ZKPs to achieve verifiability. Nexus and Nexus Zero applications can be written in traditional programming languages, with starting support for Rust.
Both Nexus and Nexus Zero’s execution layers are based on virtual machines with a traditional von Neumann architecture, which means that programs are executed within an environment that exposes memory, storage and I/O functionality (+ stack and heap) which allows traditional Rust programs to be ported as-is into the networks (except for evident required limitations, like determinism).
Nexus applications run in dedicated PoS-based decentralized cloud computing networks, which are essentially a form of general-purpose “serverless blockchains” connected directly to Ethereum. As such, Nexus applications do not inherit Ethereum security, but in exchange achieve much higher computational capabilities (e.g. compute, storage and event-driven I/O) due to their reduced network size. Nexus applications run on a dedicated cloud which reaches internal consensus, and provides a “proof” (not a real proof) of verifiable compute through network-wide threshold signatures verifiable within Ethereum.
Nexus Zero applications do inherit Ethereum security, as they are general-purpose programs accompanied by zero knowledge proofs (this time “real” proofs) which can be verified on-chain on the BN-254 elliptic curve.
Nexus and Nexus Zero applications are compatible with any EVM-compatible execution layer. We expect Ethereum developers who wish to scale their applications with maximum security will use Nexus Zero as a source for off-chain compute, as it inherits Ethereum security, and we expect developers who are willing to sacrifice Ethereum security for increased computational capabilities to use a Nexus Cloud (of arbitrary size) as a source for off-chain compute, which allows them to remain in the Ethereum ecosystem (and not having to use, for instance, an application-specific blockchain like Cosmos).
Further, since Nexus is designed to run any deterministic WASM binary in a replicated setting, we expect that it will be used as a source of liveness / decentralization / fault-tolerance for proof-generating applications, including zk-rollup sequencers, optimistic rollup sequencers and other provers like Nexus Zero’s zkVM itself.
- We introduce Nexus Labs, a scientific organization dedicated to making Ethereum maximally useful.
- We introduce Nexus, a Decentralized Cloud Computing Network powered by multi-party computation, state-machine-replication and a general-purpose WASM-based VM.
- We introduce Nexus Zero, a decentralized zero-knowledge cloud computing network powered by a general-purpose zkVM.
- Formally, Nexus and Nexus Zero are our attempts at achieving verifiable cloud computing that can scale the computational, storage and I/O capabilities of Ethereum applications.
- Both Nexus and Nexus Zero applications are designed to support traditional programming languages like Rust.
We’re based at Stanford, California and our team has experience building zk-rollups at zkSync, WASM VMs at Polkadot and doing cryptography research at Stanford. We are still in development, and plan to open-source our technology. We welcome feedback from the Ethereum community, and are actively hiring scientists and engineers. Please email us at email@example.com if you’d like to learn more, collaborate, have suggestions or are interested in doing research with us.
- How does Nexus / Nexus Zero compare to rollups? Rollups are stateful off-chain scaling solutions which 1) inherit Ethereum’s security and 2) “rollup” transactions on an off-chain state tree together. Nexus and Nexus Zero are decentralized application-specific general-purpose verifiable cloud computing networks that connect to any Ethereum-compatible execution layer. Nexus does not inherit Ethereum security (as Nexus Clouds have internal consensus) while Nexus Zero does (as its proofs can be verified on-chain). Both Nexus and Nexus Zero are designed to scale the compute, storage and I/O capabilities of individual Ethereum applications through an event-driven architecture, and not to provide a permissionless transaction-driven blockchain execution layer like rollups.
- Is Nexus stateless? No, Nexus applications are stateful, whereas Nexus Zero applications are stateless. Nexus networks are essentially a form of externally-aware application-specific “serverless” blockchains, which support any stateful computation which changes state through external (Ethereum) events. Nexus Zero applications are currently just pure computations running on a general-purpose zkVM.
- Can you run an EVM on Nexus? Theoretically, yes, as one simply needs to run an instance of the EVM that compiles to WASM, similar to NEAR’s Aurora. This essentially enables developers to launch their own “serverless” EVM sidechains. However, I personally don’t see any use for this if application-specific rollups are more widely adopted as they have superior security guarantees.
- How does Nexus / Nexus Zero compare to other non-rollup scalability solutions? Truebit can be thought of a stateless verifiable cloud computing platform based on an optimistic (fraud-proof based) mechanism. Nexus Zero is a (currently) stateless verifiable cloud computing platform based on zero-knowledge proofs (validity-proof based). Nexus is a stateful verifiable cloud computing platform based on state-machine-replication and MPC.
- How do specific components work? Check our research blog for high-level descriptions: https://research.nexus.xyz (more to come).

Providence, RI – This time on the Engineer's Corner let's talk about CODECS. Short for "encoder / decoder," codecs are a fact of modern life; used in cellphones, digital cable TV, digital television, the internet, you name it! Anywhere there's data, there's probably a codec involved.
Today, as befitting a radio station, we'll talk about audio codecs. You've almost certainly used one before: any time you've listened to an MP3, you've listened an audio file encoded with the MPEG-1 or -2 Audio Layer III (hence "MP3") file codec. If you've listened to RIPR's webcast, you've heard the streaming version of the MP3 codec. Or perhaps you've listened to "M4A" files from iTunes? That's the MPEG-4, Part 14 wrapper around an Advanced Audio Coding (AAC) codec. Or if you've talked on a cellphone, you've heard a given codec (they tend to be proprietary to the wireless carrier). Or used Skype, which uses their own "SILK" codec.
Or if you were listening to WELH 88.1FM in Providence over last weekend, you heard the Comrex B.R.I.C. codec we used while our main studio/transmitter audio link was being repaired (the main was having repeated, intermittent dropouts). Didn't hear the difference? GOOD! You're not supposed to! :-) Ideally, a codec is "transparent," meaning you can't really hear the difference. Achieving transparency is usually a tricky balance between audio fidelity and latency/delay.
Usually, the more delay you introduce with a codec, the more time its algorithms have to examine the audio, decide which bits must be saved and which can be "safely" discarded, and the more time the far end of the connection has to "buffer" against the inevitable loss of data especially across the public internet. So the more delay, the better the sound and/or the more reliable the connection.
But not every application has the "luxury" of long delays. Cellphone conversations, for example, need to keep that delay to a few hundred milliseconds. So their codecs are designed to sacrifice audio fidelity to maintain low delay and reliable connections.
Broadcast applications, though, often don't have that luxury either. They need low delay, reliable connections, AND broadcast-quality audio. The secret in that is the codec must be designed especially for those traits. Such codecs are only *required* by a comparatively small population so they tend to be pretty expensive. The Comrex B.R.I.C.-Link device RIPR employs run about $1300 each, and you need one at each end of the connection! And even then, there's not always a free lunch but broadcast devices like Comrex's are designed to automatically adjust the fidelity and delay "on the fly" to adapt to changing network conditions. So maybe not quite a free lunch, but it's getting free double meat on your grinder.
Mmmm time for lunch! See you next time!

test: :white_check_mark: improve speed of joint_trajectory_controller tests
Summary:
This PR mainly focuses on changing joint_trajectory_controller/test/test_trajectory_controller_utils.hpp:updateController to be synchronous for reliability which has the added benefit of making them run faster. On my system, this change brings the joint_trajectory_controller tests from 26.3s to 5.24s.
Specific points of interest and requests for feedback:
joint_trajectory_controller/src/joint_trajectory_controller.cpp::publish_state
I made the state_update_rate parameter not rate limit when set to 0. This is a breaking change for that parameter if someone uses it to disable the controller. My argument for this change is that other controllers behave that way and that is a user wants to disable the controller, they can do that through the lifecycle functionality and not through the update rate limiter. This was done because it makes the tests easier to work with if you don't have to arbitrarily wait for the filter to allow updates.
joint_trajectory_controller/test/test_trajectory_controller.cpp::TrajectoryControllertestParameterized.zero_state_publish_rate
I removed this test as it checks for the above point.
joint_trajectory_controller/test/test_trajectory_controller.cpp::TrajectoryControllertestParameterized.test_state_publish_rate
I changed this test to not be parameterized as it doesn't change behavior in response to the parameters. I suspect that it was originally made that way because almost all of the tests are parameterized and the author was just following the other test examples; however, since this test requires a sleep for it to work, it is inefficient to run it several times when each time is identical.
Additional notes:
This PR is intentionally held back from the tip of master at this point in time because master is unstable and not building nor passing tests.

This will likely need something like https://github.com/ros-controls/realtime_tools/pull/73 as I believe the tests are failing now because the realtime loop fails at trylock. Will move to draft for now.
I'd say the update method was changed similarly with #858: But I made it updating with a fixed update rate instead of calling update() only twice as proposed here.
I avoided the problem with trylock by still using the correct clock for the message-tests, and don't rely on the publisher for the other tests.
The part with the wait_set might be an improvement, but currently there isn't any problem with the subscriber. I'll keep that in mind if any problem arises.

This article is from the Esperanto FAQ, by Mike Urban email@example.com and Yves Bellefeuille firstname.lastname@example.org with numerous contributions by others.
The main Usenet newsgroup devoted to Esperanto is soc.culture.esperanto.
It has an estimated readership of several tens of thousands. The group's
charter specifies that postings may be in Esperanto on any topic, or
about Esperanto in any language (e.g. informational postings or requests
The preferred language of soc.culture.esperanto is Esperanto. Beginners
are ESPECIALLY ENCOURAGED to post in Esperanto, or maybe bilingually in
Esperanto alongside their native tongue. The complete text of the
charter is available at:
If you are cross-posting articles to other newsgroups, please do NOT
post in Esperanto, unless English (or the usual language of that
newsgroup) is also included, preferably as the primary language. Aside
from being rude, such postings have tended to create a lot of unwanted
cross-posted response traffic, usually of an anti-Esperanto inflammatory
nature. Similarly, while it may sometimes be appropriate to mention
Esperanto in other newsgroups, continued discussion of Esperanto in
inappropriate groups like comp.lang.c will generate more heat than
light, and should be avoided.
For those who cannot read the newsgroup, there is a "news to mail
gateway" which sends the postings to subscribers by E-mail. All
correspondence related to the mailing list should be sent to:
Every message sent to the mailing list is forwarded to
soc.culture.esperanto, and every article from soc.culture.esperanto is
forwarded to the mailing list. Thus, if you are reading the newsgroup,
you do not need to be on the mailing list.
To UNsubscribe from the mailing list, again send a message to:
The newsgroup is also gatewayed to the FidoNet echo Esperanto (see below
Incidentally, the link between the newsgroup and the mailing list means
that mailing list members will sometimes see strange messages having
nothing to do with Esperanto, caused when some lackwit cross-posts a
message to all the soc.* newsgroups. These people do not read the
newsgroup anyway, so replies sent to the mailing list (rather than the
original sender) will not reach them.
The newsgroup alt.uu.lang.esperanto.misc should deal in principle with
Esperanto instruction ("UU" stands for "Usenet University"), but it is
little used in practice. Still, it is an appropriate place for
beginners' questions, information on learning Esperanto, etc.
The two groups just mentioned -- soc.culture.esperanto and
alt.uu.lang.esperanto.misc -- have existed for several years. Very
recently, some new groups have been created in the alt.* hierarchy.
Because of the rules which apply to that hierarchy, alt.* groups are
often created without any real need and with no clear purpose.
There is some traffic in alt.talk.esperanto, mostly articles
cross-posted from soc.culture.esperanto or other groups.
There are also several groups in the newly-created alt.esperanto.*
hierarchy, but their propagation is poor and they are hardly used,
except perhaps for alt.esperanto.beginner.
In short, soc.culture.esperanto (and its corresponding mailing list) is
appropriate for all posts in or about Esperanto. If desired, questions
about learning Esperanto, help for beginners, and the like may be posted
instead in alt.uu.lang.esperanto.misc or, perhaps, in
alt.esperanto.beginner, but they are still entirely appropriate in
soc.culture.esperanto. It is probably best to ignore the other groups.

18 bite-size games for 1-4 players. Every game is different and each takes about 10 minutes. Draw, draft, match, pass, count, memorize, toss, bluff, place, score and discard your way to victory.
A hand drafting game for 2-3 players. Deal all the cards into 3 rows of 6 cards, alternating face-up and face-down. On your turn take 1 face-up card and 1 face-down card next to it into your hand (in a 2 player game, take only 1 of the last 2 cards). The game is over when all the cards have been drafted. Add your cards that have 2 or more of the same number, 3 or more in numerical order, or 4 or more of the same color. Then subtract your highest card with no match to get your score. The player with the highest score wins.
A strategy placement game for 2-3 players. Split the deck into hands of 6 cards, one color for each player. The player who goes first must place a card face-up in the middle of the table as their first turn. On every other turn, place a card adjacent to any card on the table: 1) your card must be 1 higher or 1 lower than any card adjacent to it; 2) there can only be up to 3 rows with up to 5 cards in each row. If you can't place a card, you must pass. The game is over when all players pass. Add the the cards left in your hand to score. The player with the lowest score wins.
A match game for 2-4 players. Deal all cards face-down in a grid of 6 across and 3 down. On your turn, turn 3 cards of your choice face-up. If all 3 are the same number, place them in your scoring area and take another turn. If not, turn them back face-down and end your turn. The game is over when all the cards have been taken. The player with the most sets of 3 is the winner.
A bluff & push-your-luck game for 2-4 players. Deal each player 1 card face-down and 1 card face-up. On your turn, you may draw 1 card face-up or pass. If the total of your visible cards is 12 or over, you must pass. The game is over when all players pass. Reveal your face-down card and add your cards to score. The highest score 12 or under wins.
A fishy sort of game for 2-3 players. Deal 4 cards to each player. On your turn, you may ask another player for card of a given number from their hand. If they have any, they must give it to you and you may take another turn. If not, you must draw a card. If the card you draw is the number you just asked for, you must take another turn. Place any set of 3 cards of the same number you get into your score pile. The game is over when all the cards have been played. The winner has the most sets of 3.
A game of luck and discards for 2-3 players. Deal 3 cards to each player. On your turn discard a card that is either 1 higher or 1 lower than the face-up card on the discard pile. If you cannot, draw a card. If there are no cards to draw, shuffle the discards into a new deck and draw. The game is over when a player discards their last card or if no one can discard from their hand. The winner has the least cards left in their hand.
A memory game for 1 player. Shuffle and place the deck face-down. On each turn guess “even” (2, 4, 6) or “odd” (1, 3, 5) and draw a card. If your guess was correct, discard the card face-up and take another turn. If you were incorrect, place all the discards face-down on top of the deck and try again from the start. The game is over when you correctly guess or remember all the cards in the correct order. Track the number of times you had to start over as your score, where lower is better. Make it more difficult by guessing colors (orange, green or pink), guessing numbers, or both. Challenge your friends to beat your score.
A pass and keep game for 2-3 players. Deal cards face down to each player (9 cards for 2 players or 6 cards for 3 players). On each turn all players choose and keep 1 card from their hand and place it face-down on the table. Then everyone must pass their hand to the player on their left and reveal the card they kept. The game ends when all the cards have been revealed. Add your cards that have 2 or more of the same number, 3 or more in numerical order, or 4 or more of the same color. Then subtract your highest card with no match to get your score. The player with the highest score wins.
A sudoku-like placement game for 1-3 players. Deal 3 cards to each player. On your turn, place a card on the table: 1) adjacent to another card; 2) in such a way that you do not make any row or column total higher than 12. Score 1 point for any row or column that you make add up to exactly 12. If you cannot place a card, you must pass your turn, otherwise draw a card to end your turn. The game is over when you run out of cards to play. The winner has the highest score. For solo play, try to beat your highest score.
A push-your-luck game for 1 player. Find and place the Green 6 card face up on the table. This is your starting room and gives you a starting health of 6. Deal the rest of the cards face-down around your starting card until you have 3 rows of 6 cards each. On each turn you may enter a room by revealing any face-down card that’s adjacent to any face-up card. Each card has a different effect:
|Orange||Add 1-6 treasure|
|Green||Add 1-6 health|
|Pink||Subtract 1-6 health|
The game ends if you run out of health (total pink is higher than total green) or you decide to stop. Try to get the most treasure without running out of health. Challenge your friends to beat your high score.
A story making game for 2-4 players. On your turn, deal one card face-up and tell a part of a story that includes the card’s number or color (eg. “…ate 3 green spiders…”). On your turn, repeat the entire story so far. If you are successful, draw a card, place it face-up next to the last card, then tell a new part of the story (again, using the card’s number or color). If you forgot part of the story, end your turn, draw a card and place it in your score pile. Play continues until all the cards have been played or everyone has forgotten the story. The winner has the fewest cards in their score pile.
A bluff and guess game for 2-3 players.
A bluff & swap game for 3-4 players.
A push-your-luck game for 2-4 players. On your turn, shuffle the deck, draw 2 cards and place them face-up on the table.
Otherwise you may choose to draw as many pairs of cards as you dare on your turn. Add cards you've drawn to score. The game ends after 3 rounds and the winner has the highest score.
A trading game of tricks for 2-3 players. Deal out 2 cards face-up to each player. On your turn you must trade one of your cards with any opponent’s card of your choice. If you have a set of cards that add up to 7, place them into your score pile. Draw a card face-up (or 2 cards if you have none left) to end your turn. The game ends when no more cards can be played and the winner has the most sets of 7.
A dexterity game for 1-4 players. On the far end of a table, line up 6 cards face-up in a row from 1 to 6 where the 6 is furthest from you. These are your targets. On your turn toss three cards, one at a time, toward the line of cards on the table. Score each toss by which target card you land closest to without passing or touching. Keep a running total of your score. The game ends after 3 rounds and the winner has the highest score.
Use the cards to replace 6-sided dice (up to 3 dice). Shuffle and then draw 1 card for each dice in your roll.
|Add||Increase a score by a card’s value.|
|Adjacent||Cards above, below, left or right only; not diagonally.|
|Next to||Cards to the left or right only.|
|Subtract||Reduce a score by a card’s value.|

The flow of data in Rivet (and the control of that flow) is handled in two passes on the graph of nodes.
First Pass: Topological Sort & Entry Points
The first pass over nodes works on a topological sort basis. Rivet will find all nodes with no nodes that depend on them. These nodes are considered the "output nodes" of the graph.
Rivet will then find all nodes that depend on the output nodes, and so on, adding the node to a "needs to be processed" list.
Should a cycle be encountered at this point, Rivet will proceed as normal.
During the first pass, all nodes that have no dependencies (no data flowing into them) will be marked as "input nodes".
Second Pass: Execution
Starting at the input nodes marked in the first pass, rivet will execute all pending nodes in parallel.
Every time one of the nodes that is currently executing finishes, it will check to see if any of the nodes that depend on it are ready to be executed. If so, it will execute them in parallel with any other currently-executing node.
A node is defined as ready to execute if all of its dependencies have been satisfied. A dependency is satisfied if the node it depends on has finished executing and has a value to pass to the dependent node.
Control Flow Exclusions
What happens when an If node is encountered, and the output of the If node should not run? In this case, the output of the If node is the special
control-flow-excluded value. If this value is passed into any node, then that node will not execute.
Then, every dependent node of the node that returned
control-flow-excluded will also return
control-flow-excluded, and so on. In this respect, control flow exclusion "spreads" to every dependent node after the value has been returned.
Control Flow Excluded Consumers
Certain types of nodes are registered as able to "consume" a
control-flow-excluded value. This means that when the node encounters this value, it will actually run with the actual
control-flow-excluded value. This allows certain nodes to "break out" of the spreading of
Nodes that can consume
control-flow-excluded values are:
- If/Else - If the
control-flow-excludedis passed into the
Ifport, then the
Elsevalue will be passed through instead. If the
Elsevalue is not connected, then the result will again be
- Coalesce -
control-flow-excludedwill be considered "falsy" for the sake of the Coalesce node. The values will be skipped over, and subsequent truthy values connected to the Coalesce node will be passed through instead.
- Race Inputs - If one of the branches passed into the Race Inputs node returns
control-flow-excluded, then that branch will simply be not considered for the race. Other branches may still execute and return a value, which will be passed through the output of the Race Inputs.
- Graph Output - A Graph Output's
control-flow-excludedmay pass out of the graph to become one of the outputs for a Subgraph node. This way, some of the outputs of a Subgraph may not run, and others may run.
- Loop Controller - A loop controller needs to consume
control-flow-excludedvalues in order to run multiple times. Additionally, passing a
continueport counts as a "successful" iteration of the loop, and will cause the loop to run again.
The loop controller is special, however, in particular its
Break port. The
Break port will not pass a
control-flow-excluded value to the next node
until the loop has finished executing. Otherwise, the loop controller itself could not run multiple times before finally passing a value to the next node.
If any other input port to the loop controller receives a
control-flow-excluded value, then the loop controller will not run again, and will pass the
control-flow-excluded value to the node connected to
Break. Thus, it is important to use an If/Else or Coalesce node inside your loop as a "null check" to make sure the loop controller never receives a
control-flow-excluded value unless you want it to.

Error - can not use root. in the constraints expression - AnyLogic
I tried to define constraints in the optimization experiments using root. ( I did this to access top level agent in the constraints expression field).
I have the variable in the top agent
I tried this with functions, parameters, and variables, and all return the same problem
When I use root in requirements there will be no error
However, I got the following error when using root in the constraints expression:
According to https://anylogic.help/anylogic/experiments/optimization.html#:~:text=A%20constraint%20is%20a%20well,%2C%20e.g.%20parameter1%20%3E%3D%2010.
I should be able to use root in the constraints expression. See the following in the above link:
3 Specify the constraint in the Expression, Type, and Bound cells of the row. In the Expression field the top level agent is available as root.
Then, why is AnyLogic returning this error when root is used in the constraints expression?
Did you face a similar problem? What do you think is the reason?
To be honest, I think the help is wrong. Constraints are checked BEFORE a model is even created, so access to root does not make sense. I think they copied the description from the "Requirements". Those are checked after a model is instantiated.
So either use requirements or change your constraints so they do not need access to root.
This is confirmed by a quick check on the code boxes. For requirements, you can see the lightbulb:
But for constraints, there is no lightbulb:
More lightbulb info here :)
This is what I have done to avoid the root error. However, I'm asking this question because I'm afraid that this (the removal of constraints) will reduce the optimization performance. As you know, the constraints reduce the search space (this is mentioned in the help, too), but they did not mention if the requirement does the same (although they mentioned that requirements help in guiding to the solution): "A requirement can also be a restriction on a response that requires its value to fall within a specified range."
If I used requirement, what is the effect on the performance?
If I change my constraints so they do not need access to root., I will need to reduce the number of parameters (decision variables) which I'm trying to avoid as much as possible till I discover that there is no way else.

Tracy Widom type results for asymptotic distribution of the $k$-th largest eigenvalue of the sample covariance when $n, p \to \infty$?
Earlier I asked a question: Distribution of the $k$-th largest eigenvalue of in the sample covariance matrix?, but I forgot to mention that I'd like results for asymtotic regime. So, I'm posting here a modified question.
I'm new to random matrix theory, but per my understanding Tracy-Widom law describes the the asymptotic distribution of the largest eigenvalue of any square real symmetrix matrix with iid entries on the diagonal and above it, of dimension $n \times n$ as $n \to \infty$. (Please correct me if I'm wrong!).
What I'm trying to do is to connect, or at least find a resource that connect Tracy-Widom with Marcenko-Pastur law in a somewhat detailed way, as follows.
Let us assume we've a rectangular data matrix $X=[x_1 \dots x_n] \in \mathbb{R}^{p \times n}$, where the $x_i \in \mathbb{R}^{p \times 1}$ are iid column vectors. I'm not assuming here that the entries of the matrix $X$ are iid, but if you so need to answer the question, you can assume that first, and then perhaps we can see what happens when we put a covariance structure on $X$. Let, as often in the random matrix domain, let $n, p \to \infty, p/n \to c \in (0, \infty)$.I'm interested in the limiting distribution of $k$-th largest eigenvalue, when $k$ is fixed and $k$ - is varying.
Precisely, my questions are:
(1) What's the limiting distruition of the $k$-th largest eigenvalue of $\frac{1}{p}XX^{T}$, as $p, n \to \infty, p/n \to c?$
(2) Also what's the limiting distribution of the $k$-th largest eigenvalue of $\frac{1}{p}XX^{T}$, as $k, p, n \to \infty, p/n \to c, k/p \to c', c\in (0, \infty), c' \in (0,1) ?$
To show you an idea what I'm after, I'll mentiong what I found from my search:
(1)I found this paper that seems to be relevant: https://projecteuclid.org/download/pdfview_1/euclid.aoap/1481792600, but they deal with the the limiting distribution of the largest eigenvalue.
(2) This paper by Tracy and Widom: https://arxiv.org/pdf/hep-th/9211141.pdf, describes in Section E the probability density for the $k$-th largest eigenvalue. But I think there the underlying matrix is a real (or complex) symmetric (or Hermitian) matrix with iid entries on the diagonal and above the diagonal, and not sample covariance matrix.
Any help will be sincerely appreciated, as I'm super new to RMT!

how to find out at what price was future contract agreed upon?
A future contract means buying and selling at a specified price(call it agreement price) on specified date between 2 parties in future
so If a stock's spot price is 1000 and future price is 1003,how should i find the agreement price?
If it says “1003” on the executed contract, that’s what was agreed upon. Even if the 1003 was some kind of barrier / ceiling price, the actual strike price / agreement price should be in the agreement. After all, the point of the agreement is to transact at the contractually-agreed price.
@Lawrence I was talking about the futures contracts that are traded in the stock market , so how should i find the agreement price of those contracts as i dont have the actual contract with me
The strike price should be one of the parameters specified when you buy it. It affects the price of the option, so it can’t be a hidden thing.
@Lawrence yes for options strike price is given but for futures it is not given
If it isn't provided, how do you determine the price? For FX forward contracts, for example, they take the current FX rate, adjust it for 'forward points' (taking into account the relative difference in interest rates, for example), then tell you the amount of the target currency you'd get for a given primary currency. So the 1003 you mention is the agreed price.
Apologies for the wrong context in my earlier comment.
A futures contract trades at many different prices over its lifetime. Each of those prices corresponds to a different "agreement" to buy and sell the underlying. Futures trading requires margin funds (collateral) from both parties to back up the "agreement". Futures are marked to market: If the market moves against your position, you have to put up more money now or face liquidation (margin call). Futures with given terms are fungible: Only net agreements are tracked, so if you buy at 100, the market moves in your favor, and you sell the same quantity at 110, you get your profit in cash now and have no remaining obligation to accept or deliver the underlying.
Thus, while a future can be thought of as an agreement to buy and sell, it doesn't have an inherent strike price like an option. Or rather, the strike price is effectively zero: A future is equivalent to a European call option with zero strike that can be traded with high leverage. See this question.
In your example, if you buy or sell the future at 1003, you are effectively agreeing to buy or sell the underlying at that price (1003) on the expiration date (unless you offset the position before then). I say effectively in that your profit or loss will be as if this is the agreement. But the profit or loss will accumulate in cash day by day (marked to market) rather than all at once at the end.
thanks for the reply.so what i understood is that in the beginning a buyer and a seller agrees at a price and then when value of contract increases they sell that contract and that selling price would be future agreement price for the new buyer of contract right? and this goes on
so If a stock's spot price is 1000 and future price is 1003,how should i find the agreement price?
Lets say I wanted to buy your car. How we would find the agreement price?
If I wanted to know the price you paid for it, how would I find that out?
In both cases, I would have to communicate with you in some way, ie, talk to you.

Gradelyfiction Pocket Hunting Dimension update – Chapter 840 – Let the Old Man Start Streaming? various development quote-p3
Novel–Pocket Hunting Dimension–Pocket Hunting Dimension
Chapter 840 – Let the Old Man Start Streaming? week argument
Lu Ze required, “Healed? You had been harmed just before?”
All the legend state governments had been freed. They made it easier for clear out planetary point out insectoids.
Liu Lang experienced relieved. He was worried Lu Ze might be tricky to encourage. The good thing is, the latter’s att.i.tude was good. This designed him actually feel much better with regards to the younger prodigy. Lu Ze was just about one of the more important statistics during the Our Race, but he didn’t respond c.o.c.ky at all.
He knew Manager Zhu was considerably robust right before, but he didn’t be expecting the second to be a optimum point planetary point out. He could attain the legend express quickly. His combat power was approaching the celebrity point out as well.
Lu Ze’s sight flashed.
They experienced that star point out monster before. He idea they were about to kick the bucket, but fortunately, Saint Lin Dong came just with the perfect time and killed all the insectoids. Usually, they might literally kick the bucket with each other.
Never ever mind…
Lu Ze smiled in the team. “Then, I’ll go help out with other parts.”
Now, he was thinking whether he should consult the earlier man to stream the functions for them. But, the battle would be pretty strong. It had been a query of whether the Our Race even acquired streaming equipment that can cope with cosmic strategy declare confrontations.
Lu Ze could already suppose that if stuff decided to go haywire within the insectoid lair, the three backrounds would make an effort to ambush them. While they experienced Ying Ying and didn’t be concerned about protection, they didn’t need to go.
While the Blade Demon Race may be unaware of his latest energy, they would still know he inserted very first in the Four-Competition Community Getting.
Thereafter, he dragged Ana gone.
Presently, he was wondering whether he should check with the old person to flow the occasions for the children. However, the challenge can be pretty strong. It was subsequently a query of regardless of if the Human being Race even had internet streaming devices that might deal with cosmic strategy express confrontations.
There weren’t plenty of legend state insectoids this point. They had been rapidly all wiped out by using Lu Ze’s party.
Section 840 Permit the Aged Gentleman Start out Internet streaming?
Lu Ze was very interested in just what it would resemble.
Now, he was wondering whether he should inquire that old mankind to source the gatherings for them. But then, the battle could well be pretty extreme. It turned out something of whether or not the Man Competition even possessed streaming gear which could take care of cosmic program declare confrontations.
Liu Lang remarked, “The number of insectoids within the Jiya Strategy suddenly enhanced with a wide border. As you males went along to our site, we now have a little extra potential. As a result, others relocated to help the rest. Depending on numerous commanders, the lair is likely to be for the reason that direction of void s.p.a.ce. Lord Jinyao has notified one other competitions to look over and look into alongside one another.”
The ocean of insectoids was almost endless. Quite a few soldiers and adventurers didn’t get enough time to rest effectively. Therefore, Lu Ze plus the young girls needed to keep.
The water of insectoids was countless. Many troopers and adventurers didn’t get lots of time to sleep accurately. Consequently, Lu Ze as well as the young ladies had to keep.
They murdered lots of planetary express insectoids and several optimum planetary state versions as soon as they turned up.
Lu Ze could already suppose that if factors gone haywire on the insectoid lair, the three backrounds would try and ambush them. Whilst they possessed Ying Ying and didn’t need to worry about security, they didn’t need to go.
The many star state governments were freed. They really helped get rid of planetary declare insectoids.
Lu Ze’s vision flashed.
Currently, he was curious about whether he should ask the earlier guy to flow the functions for the kids. But then, the battle could be pretty strong. It had been a query of regardless of if the Individual Competition even experienced internet streaming products that could handle cosmic program express confrontations.
Lu Ze as well as the women observed the scene endearing.
He looked over Liu Lang in disbelief. “Why is he stopping us to move?”

I need somebody who is experienced in installing phpBB MOD's, and is able to install a number of modifications starting immediately.
I will probably want to do some custom tweaking here and there as well, so the more experience the better. You need to know PHP and HTML fairly well.
Please send an example of at least one board you have modded, and any other work you want to share.
I will provide FTP to a default installation of phpBB and tell you what mods I want done. You must obtain and install the MOD's, then send me a copy of the MOD install file when complete. I highly suggest using HTML-Kit so you can edit the site's files directly, you can install these very rapidly.
phpBB MOD's each have an 'estimated time' in the install file. It usually specifies a range, e.g. "30-45 minutes". I will calculate time spent at the low end of this range, so for "30-45 minutes" I will base pay on 30 minutes. The estimate is always rather high for an experienced phpBB'er.
Hangon, hangon, you were saying "I'll pay you X based on time Y which should only take you time Z". Since pay X was pointless for time Y, saying that "oh if you're decent it should only take you time Z, so it's ok" is tosh.
Much better would be to say: "Please do the following mods, tell me ho w long it took you, and I'll pay you @ $X/hr, or perhaps we can work out a deal together".
I apologise for the poster who said it's unlawful - note I didn't say it's unlawful, I said it's a ripoff, which in my eyes it is.
Sorry you took my info the wrong way. But you really shouldn't take offense, it was only constructive criticism.
Okay, sorry for reacting so harshly, but you did say "ripoff". I find it quite offensive to have anyone think I'm only willing to pay somebody $5 per hour. It's much nicer when you explain your reasoning.
While the estimates are not accurate they are indicative and serve a useful purpose. It's easy to say "tell me how long it takes ya", but it's impossible to keep track of.
Maybe I should have stated it differently, which is why I will end this offer now and save the hassle and the time I could spend just doing the mods.
P.S. I will add that many of these mods are around 5 minutes, which equates to about $20 per hour, which considering how much I make is pretty sweet for a fairly straightforward task.
Guys, again I aplogize for reacting angrily. Two people jumped on me for something I had absolutely no intention of doing, calling me a ripoff. I am absolutely not ripping anyone off, and I explained this very well. If someone insults me, I defend myself. I am an incredibly easy going person, and I've never once felt more insulted online in the years I have been a geek (basically forever).
Again, I have seen people offering to do MOD's using this same pricing structure for even less money, which is exactly why I chose to do it this way in the first place. Obviously a bad idea.
I installed six MODs in about 40 minutes last night, woohoo I just made $10 in 40 minutes off myself! How is that such a bad deal? $15 per hour for basic HTML skills is nothing to write home about but I'm not Bill Gates here.
For example, how long does it take a non-techie to get their VCR programmed compared to someone who has owned a VCR for years? Are you going to pay someone to sit there and fumble with the manual for two hours?
Please understand that instead of constructive criticism, I got two flames which basically soured this offer permanently. Wouldn't that bother you? Not only insulted, but the idea planted here that I'm promoting some kind of illegal activity, and furthermore abusing minimum wage standards which is just ludicrous.

That's simply not true. I have been doing custom development for years, and I do plenty of fixed price contracts. Clients rarely want to pay for service hours, it's a huge mess for most people to keep track of and understandably so. Look at WHT or SP or any other related forum, and you see hundreds of fixed price service requests. If I'm doing a lousy job and it takes me too long, it's my own fault.
yegorpb - I don't care if you use EasyMOD or voodoo. Glad you find this humorous though.

public final class NamespaceMapper extends NamespacePrefixMapper
|Constructor and Description|
|Modifier and Type||Method and Description|
Returns a list of (prefix,namespace URI) pairs that represents namespace bindings available on ancestor elements (that need not be repeated by the JAXB RI.)
Returns a preferred prefix for the given namespace URI.
public String getPreferredPrefix(String namespaceUri, String suggestion, boolean requirePrefix)
As noted in the return value portion of the javadoc, there are several cases where the preference cannot be honored. Specifically, as of JAXB RI 2.0 and onward:
String), partly to simplify the marshaller.
JAXBContextincludes classes that use the empty namespace URI. This allows the JAXB RI to reserve the "" prefix for the empty namespace URI, which is the only possible prefix for the URI. This restriction is also to simplify the marshaller.
namespaceUri- The namespace URI for which the prefix needs to be found. Never be null. "" is used to denote the default namespace.
suggestion- When the content tree has a suggestion for the prefix to the given namespaceUri, that suggestion is passed as a parameter. Typicall this value comes from the QName.getPrefix to show the preference of the content tree. This parameter may be null, and this parameter may represent an already occupied prefix.
requirePrefix- If this method is expected to return non-empty prefix. When this flag is true, it means that the given namespace URI cannot be set as the default namespace.
public void setContextualNamespace(String contextualNamespaceDecls)
public String getContextualNamespaceDecls()
Sometimes JAXB is used to marshal an XML document, which will be used as a subtree of a bigger document. When this happens, it's nice for a JAXB marshaller to be able to use in-scope namespace bindings of the larger document and avoid declaring redundant namespace URIs.
This is automatically done when you are marshalling to
those output format allows us to inspect what's currently available
as in-scope namespace binding. However, with other output format,
OutputStream, the JAXB RI cannot do this automatically.
That's when this method comes into play.
Namespace bindings returned by this method will be used by the JAXB RI, but will not be re-declared. They are assumed to be available when you insert this subtree into a bigger document.
It is NOT OK to return the same binding, or give the receiver a conflicting binding information. It's a responsibility of the caller to make sure that this doesn't happen even if the ancestor elements look like:
<foo:abc xmlns:foo="abc"> <foo:abc xmlns:foo="def"> <foo:abc xmlns:foo="abc"> ... JAXB marshalling into here. </foo:abc> </foo:abc> </foo:abc>

Again, you could bookmark it, but if your bookmark list is getting a little carried away, creating desktop shortcuts can free up that long list a bit. For me, I have my bookmarks synced across my two computers.
Loading | Jamf Nation
However, one of my computers is mostly meant as a streaming machine. TV shortcut. Having these shortcuts on my desktop makes it really quick and easy to fire up a TV show or movie and get to watching without having to click through a bunch of nonsense.
However, I digress. To add a website shortcut to your desktop in OS X, the process is rather easy. Just follow these simple steps:.
Open up your web browser and navigate to the website that you want as a desktop shortcut. Decrease the web browser window size just a bit so that you can see the desktop. To adjust the size of the window, simply hover over any of the edges and then click-and-drag your mouse.
Learn why people trust wikiHow. The wikiHow Tech Team also followed the article's instructions and validated that they work.
Learn more Method 1. Open your web browser. You can use this same method for either Internet Explorer or Firefox. If you use Microsoft Edge, you'll need to open Internet Explorer to do this, as Edge does not support this feature. The shortcut you create will usually open in the browser you created it from, regardless of your default browser. Visit the website you want to create a shortcut to.copagtevilu.ga
Open the exact site you want to make a shortcut for. You can make a shortcut for any website, but you may still be prompted to log in if the site normally requires it. Make sure the browser isn't full screen. You'll need to be able to see your desktop in order for this to work easily. Click and drag the site's icon in the address bar. You'll see an outline of the object appear as you drag.
Release the icon on your desktop. A shortcut to the website will appear with the website's title as the name. The shortcut will use the website's icon if it has one. Double-click the shortcut. If you used Internet Explorer to create the shortcut, running the shortcut will always open it in Internet Explorer. If you used Firefox, it will open in your default browser.
Method 2. Open the website in Chrome in Windows. If you use the Chrome browser, you can create a shortcut to the website on your desktop that uses the website's custom icon favicon. This feature is not currently available on Mac computers. You'll find this in the upper-right corner of the Chrome window. If you don't see this option, you may not be running the latest version of Chrome.
Enter a name for the shortcut. By default, the shortcut will have the same name as the site's title. You can change it to whatever you'd like. Select whether to open in a window or not. If you check the "Open as window" box, the shortcut will always open in its own window, making it act more like an application. This can be very useful for services like WhatsApp messenger or Gmail.
Click "Add" to add it to your desktop. You'll see a new icon on your desktop, which will be the same icon that the website uses.
How to Create Website Shortcuts in Chrome?
Double-click the shortcut to open it. If you didn't select "Open as window," the shortcut will open in a regular Chrome browser window.

Stop sweeping your failing tests under the RUG
Hello and welcome to this week’s rant on bad practices in test automation! Today’s serving of automation bitterness is inspired by a question I saw (and could not NOT reply to) on LinkedIn. It went something like this:
My tests are sometimes failing for no apparent reason. How can I implement a mechanism that automatically retries running the failing tests to get them to pass?
It’s questions like this that make the hairs in my neck stand on end. Instead of sweeping your test results under the RUG (Retry Until Green), how about diving into your tests and fixing the root cause of the failure?
First of all, there is ALWAYS a reason your test fails. It might be the application under test (your test did its work, congratulations!), but it might just as well be your test itself that’s causing the failure. The fact that the reason for the failure is not apparent does not mean you can simply ignore it and try running your test a second time to see if it passes then. No, it means there’s work for you to do. It might not be fun work: dealing with and catching with all kinds of exceptions that can be thrown by a Selenium test can be very tricky. The task also might not be suitable for you: maybe you’re inexperienced and therefore think ‘forget debugging, I’ll just retry the test, that’s way easier’. That’s OK, we’ve all been inexperienced at some point in our career. In a lot of ways, most of us still are. And I myself have not exactly been innocent of this behavior in the past either.
But at some point in time, it’s time to get over complaining about flaky tests and doing something about it. That means diving deep into your tests, how they interact with your application under test, getting to the root cause of the error or exception being thrown and fixing it, for once and for all. Here’s a real world example from a project I’m currently working on.
In my tests, I need to fill out a form to create a new savings account. Because the application needs to be sure that all information entered is valid, there’s a lot of front-end input validation going on (zip code needs to exist, email address should be formatted correctly, etc.). Whenever the application is busy validating or processing input, a modal appears that indicates to the end user that the site is busy processing input, and that therefore you should wait a little before proceeding. Sounds like a good idea, right? However, when you want your tests to fill in these forms automatically, you’ll sometimes run into the issue that you’re trying to click a button or complete a text field while it is being blocked by the modal. Cue WebDriverException (“other object would receive the click”) and failing test.
Now, there are two ways to deal with this:
- Sweep the test result under the RUG and retry until that pesky modal does not block your script from completing, or
- Catch the WebDriverException, wait until the modal is no longer there and do your click or sendKeys again. Writing wrappers around the Selenium API calls is a great way of achieving this, by the way.
Option 1. is the easy way. Option 2. is the right way. You choose. Just know that every failing test is trying to tell you something. Most of the time, it’s telling you to write a better test.
One more argument in favour of NOT sweeping your flaky tests under the RUG, but preventing them from happening in the future: some day, your organization might start, you know, actually relying on these test results. For example as part of a go / no go decision for deployment into production. If I were to call the shots, I’d make sure that all my tests that I rely on for making that decision were:
- Returning reliable test results, all the time
- Checking the right thing (but that’s a different post altogether)
Really, it’s time to quit tolerating flaky tests. Repair them or throw them away, because what’s the added value of an unreliable test?. Just don’t sweep your failing tests under the RUG."

We are a level 3 PCI Merchant and are looking at changing our current remote access method for our 3rd party support vendors.
Of course, PCI says it has to be 2 factor auth, which I think most of the big products do at this point via logon credentials and a cert/token.
The second part that I am having a hard time with, is our corporate office is requring that the solution not be "always on." In other words, if one of our vendors wants to connect to the network, the IT team (or someone else on property) must approve/open up the connection. This can be via a phone call where we have to enter a passcode, physically starting an 'invite' session, the vendor calling for a unique session ID each time, etc. It cannot be starting/stopping the service manually, it must be automatic so no one forgets to turn the service off when the session ends...
Of course, some of these methods are more convenient than others - what is everyone else out there using for 3rd party vendor/support connections into your network?
After a little digging, I actually found in v2.0 of the PCI requirements, 12.3.9 specifically calls out the need to activate/deactivate the remote connection methods before and right after the vendor is done.
Here's the snip: 12.3.9 Activation of remote-access technologies for vendors and business partners only when needed by vendors and business partners, with immediate deactivation after use
So, given this info, how exactly would LogMeIn or TeamViewer handle this, even with their 2-factor auth? It sounds like no matter what, a property resource needs to open/start the remote session and it needs to automatically terminate/stop the service after the vendor disconnects.
Brand Representative for ISON, LLC
We have power customers that have to deal with federal regulatory requirements (NERC CIP) that have the same stipulations. What a couple of them have done is create a VPN account on a Cisco ASA or Checkpoint with two factor authentication and strict access controls (they can only get to the systems they are supporting with all the logging turned on). The client keeps the token/two factor device. When the vendor needs access the vendor support tech calls the client to get the passcode on the token. Once they close the session the VPN won't reconnect without another call to the client for the new passcode on the token. One client also pulls the VPN logs to show where the vendor went and for how long as proof.
Brand Representative for Bomgar
_Tyler, we've had a number of customers select Bomgar for PCI compliance around remote access. MICROS uses Bomgar for PCI compliant remote access to over 330,000 property management and point of sale systems. InterContinental Hotels Group chose us for similar reasons. We also published a research paper on PCI compliant remote access with EMA.
Would be happy to talk more about it. Secure remote support and access is a major focus for us.
Thanks for the replies. In our situation, a physical token is not an option, as it's a 3rd party company with many different people that may be connecting.
Justin - I actually have been on the client side of Bomgar with Micros, seemed like it worked well. I've actually setup a call with your sales guys next week, thanks for the links.

Classes are the “parts” of an object-oriented program.
Testing makes sure that the parts work correctly.
If the individual classes don’t work correctly, the overall program is probably not going to work correctly. Therefore, it is very important to have a good set of tests for the classes in your program.
JUnit is a unit testing framework for Java programs. To use JUnit, you write test classes. A test class is designed to test one Java class. It contains one or more test methods. Each test method is designed to test one particular feature of the class being tested.
General structure of a JUnit test class
The test class’s fields (member variables) store references to objects (generally, instances of the class being tested). These fields and the objects they point to are called the test fixture.
A test class’s setUp method creates the test fixture objects. This method is called automatically before each test method is called. It must be marked with the @Before annotation.
The test methods call methods on the test fixture objects and check to see that the methods compute the correct result, typically by calling an assertion method. Assertion methods are methods defined by the JUnit framework specifically for checking that calls to methods in classes being tested compute the expected result. Each test method must be marked with the @Test annotation.
Ideally, a test method should focus on one particular method to be tested.
Kinds of JUnit assertion methods:
Most assertions in JUnit test classes will boil down to checking that the return value of a method call is equal to an expected value.
If an assertion is not satisfied, it causes the test method containing the assertion to fail. If all assertions in a test method are satisfied, the test method containing the assertion passes. The goal of testing using JUnit is that all assertions in all test methods should pass.
Eclipse has built-in support for running JUnit tests. To run a JUnit test class within eclipse, right-click on the test class, and choose Run As…→JUnit test. The result will be displayed in the JUnit window:
- Green bar: all of the test methods passed
- Red bar: at least one of the test methods failed
As an example, let’s consider an improved version of our Point class:
Here’s a very simple JUnit class for testing the Point class. We’ll call the test class PointTest.
This is a very simple example, but it demonstrates the basic idea: for each method in the Point class, we want to have one or more test methods which check whether or not the method behaves correctly using some test input.
Note that there is one method in Point that we didn’t test - the print method. It is actually quite difficult to test methods that write output to System.out.

test: Improve instruction-counting VM benchmark
What ❔
Replaces iai with an alternative; brushes up instruction counting in general.
Why ❔
The library currently used for the benchmark (iai) is unmaintained.
It doesn't work with newer valgrind versions.
It doesn't allow measuring parts of program execution, only the entire program run.
Checklist
[x] PR title corresponds to the body of PR (we generate changelog entries from PRs).
[x] Tests for the changes have been added / updated.
[x] Documentation comments have been added / updated.
[x] Code has been formatted via zkstack dev fmt and zkstack dev lint.
Observations so far:
Completely subjectively, the new approach has better DevEx; e.g., it allows filtering run benches and allows integrating reporters directly into the benchmark logic (see code).
Instruction / cycle count measured using the new approach seems to correspond to the old approach if ~90M instruction overhead on general and VM initialization is subtracted.
The new approach seems to better correlate with real-time benchmarks (more w.r.t. instructions than cycles), although there are still outliers. E.g., here are test results on my M2 Macbook:
time cycles instructions cycles/s, B instr/s, B
fast/deploy_simple_contract 1.4662 ms 148594653 13479007 101.4 9.19
legacy/deploy_simple_contract 2.4865 ms 175808750 31190368 70.7 12.5
fast/access_memory 39.774 ms<PHONE_NUMBER> 715607457 27.1 18.0
legacy/access_memory 615.71 ms<PHONE_NUMBER>0<PHONE_NUMBER> 19.5 11.9
fast/call_far 31.002 ms 538142795 419103438 17.4 13.5
legacy/call_far 123.89 ms<PHONE_NUMBER><PHONE_NUMBER> 17.9 10.1
fast/decode_shl_sub 22.284 ms 638405039 462780306 28.6 20.8
legacy/decode_shl_sub 513.15 ms<PHONE_NUMBER>4<PHONE_NUMBER> 21.8 13.4
fast/event_spam 38.736 ms 804507408 517321574 20.8 13.5
legacy/event_spam 335.45 ms<PHONE_NUMBER><PHONE_NUMBER> 20.5 12.3
So, the number of instructions per second is roughly the same for all benches and it has the expected order of magnitude 🙃
Not so good observations:
As expected, due to measuring parts of program execution, the benches are more sensitive to the setup logic. I've observed ~1% instruction / cycle changes caused by trivial changes in the benchmark source (e.g., iterating over benchmarks in the reverse order; running the init bench before / after other benches or not running it at all, etc.). To be fair, fluctuating results were partially true for the old approach as well, but probably to a lesser degree. Maybe, the results would be more stable with cachegrind instrumentation enabled, but that'd require installing a new version of valgrind.

Inquiry Based Pedagogy for Computational Surfaces in GeoscienceRisa Madoff, Geology and Geological Engineering, University of North Dakota-Main Campus
Several occurrences have awoken me to the kinds of barriers to teaching computational thinking as well as to the needs that exist for developing a curriculum in the Geosciences. I did not have a background in programming when at the start of my PhD program in Geology I was given a modeling type of project in Geomorphology. However, I did have a background in Philosophy and in the roots of logical reasoning. While learning programming and applying numerical methods did not come easily, I had a sense and appreciation for the reasoning, which in the end allowed me to ask the questions I needed in order to unpack my dissertation. In discussions with other graduate students I realized that their experience with applying programming for complex analyses and experimenting with models was unlike mine. Even our experiences with the layouts of our projects were very different, even though modeling was involved in both. I certainly did not use as advanced techniques in MATLAB as most modelers do. Yet in the process of producing raw point-cloud generated hillslope surfaces with a terrestrial LiDAR and importing them into MATLAB, learning what combinations of little codes could be applied to reconstruct the natural surface and experimenting with different parameters that degraded it through time, I learned what evolution of the land surface meant, I learned what modeling was, and I learned what questions could, should and needed to be asked. I am still convinced that little could have substituted for the understanding I gained by the approach I was forced to take.
A subsequent awakening moment occurred when teaching an Honors class with a mix of majors. I tried to explain different ways of reasoning and started with deduction and induction as examples of formats. None of the students knew what they were. Only one, a physics major, said he had heard "deduction" used in an upper level math class, but it was never explained. The rest said they had never heard of them. This encounter certainly explained much of what I have been experiencing as an instructor. Without ever having been taught to reflect on one's own thought process or on what is prerequisite for thinking, how can science and scientific methods ever be taught and learned? If it is true that students are no longer being taught the basis of formal reasoning, except behaviorally in math classes where they solve math problems, we need to think about what the consequences can be for cognitive development, where future generations do not know the foundations of formal thinking that underlie language, the ability to formulate hypotheses and question assumptions, and the sense to know what evidence is and how to evaluate it. How will such a gap affect students' abilities to read and comprehend? Can we expect students to be able to even form the mental constructs to receive and understand explanations? The longer I am in higher education, the more the situation appears to be the norm, rather than an exception.
Since no one has provided an alternative to the formal reasoning traditionally associated with all that most have come to relate with science, I feel an urgency to do something. I am also intrigued by the messy process I came to learn about quantifying a hillslope surface, a very formal matter for a computer and a programmer. Reflecting on this, I have been eager to develop curriculum to teach computational thinking about the Earth's surface. What I suggest is something akin to teaching reasoning through a natural language approach. That is, teaching logical reasoning through the back door, where students are starting out. In other words, first have students track physical objects that will be tied to numerical constructs. Put students in the experience of having to need computation to understand data they physically generated. Terrestrial laser scans work really well for this: once the workings of the laser mechanism and the instrument positioning are explained there is a straightforward connection between digital points (point clouds) generated and coordinates in a measurable 3-D framework. For a natural surface, a collection of millions of sets of coordinates can be imported into MATLAB as a simple text file. From these points, with a physical grounding, a quantified surface can be constructed. This is the first of many steps where students reflect on the physical relevance of the data. The direct connection between the physical origins of the numerical data is important for understanding the significance of the computations that generate models of processes. This step paves the way for the teaching numerical modeling of a land surface through different time scales and for testing environmental parameters. Without this initial direct connection, modeling can easily become an exercise of number crunching and detached abstractions. It also allows inquiry and questioning that require reviewing the natural conditions against the models.
Using the MATLAB generated elevation model of a hillslope surface, an instructor can develop lines of inquiry related to asking how might we discover?....the number of years to smooth, degrade, or diffuse a surface given certain parameters and an accepted equation; how did the erosion rate vary across the surface; how did the micro-topography vary across the surface? Attempting to answer such process questions can lead to the students themselves, hopefully, asking the scientific questions of the causes of variability, applications of various time scales and how things might have varied through time, how can we design experiments that would allow us to test different conditions and scenarios, generate new data, and modify models? Using the lines of inquiry, students can be asked to generate the thinking needed and the short sets of code that would enable a program to run and produce the needed values. The final stage would be in implementing the codes, testing for errors and troubleshooting, and optimizing.
There are many options for where the course design might work best - a specialty designed course in Surface Processes, An introductory Earth process modeling course for graduate and senior level undergraduate students, a Geomorphology course (in a department with an expanded curriculum in computation). Departmental support is certainly preferable to trying to develop what is considered novel curriculum in a vacuum. So there may be a need to present and justify the pedagogy to a department before teaching it. Akin to teaching fine arts, there needs to be room and accommodation for experimentation, for messiness, and for working out the reasoning behind the syntax in order to build the mental constructs that might have been missing. The point is, if we are trying to draw in those without the background of applying formal reasoning, we need to make programming and computation appear something less formal and more akin to inquiry, experiment, and artistic exploration.

Commented: Agra Sakti on 24 Apr 2021
Hi, it is my first time here. So I was trying to find parameter value of k1 and k2 by using fzero on the phi = modeling data - experiment data. But the fzero keep giving me an error of "Index exceeds array elements (1)" in "konstanta = fzero (...) line. The kguess array has 2 element and so I write the K(1) and K(2). Where did I code wrong? Thanks in advance, Agra.
kguess = [0.5 0.1];
konstanta = fzero(@fobj,kguess);
k1 = konstanta (1);
k2 = konstanta (2);
function phi = fobj(K)
k1 = K(1);
k2 = K(2);
tspan = [0 3.5];
CFFAdata = 0.096;
CMEOdata = 1.636;
initial = [2.15 2.39 0 0];
[tmodel,Cmodel] = ode23s(@fun,tspan,initial,,K);
CFFAmodel = Cmodel (length(Cmodel),1);
CMEOmodel = Cmodel (length(Cmodel),3);
phi = (CFFAmodel-CFFAdata)+(CMEOmodel-CMEOdata);
function dCdt = fun(t,c,K)
dCdt = zeros(4,1);
dCdt(1) = -(K(1)+K(2))*c(1)*c(2);
dCdt(2) = -( K(1)+K(2))*c(1)*c(2);
dCdt(3) = K(1)*c(1)*c(2);
dCdt(4) = K(2)*c(1)*c(2);

Looking at the setup of the problem, it seems like you are trying to find out the value of 2 variable. I think fzero function is not suitable for such setup of the problem because the function handle which this function take as input only accept a scalar input, check out the input function handle description here.
I hope this address your issue.

Whining About Passwords
There's a lot to complain about with passwords. Mostly it comes down to scale: A handful of accounts is easy enough to deal with. But nowadays who has only a handful? You have to get an account for most anything of real value on the Internet. Each of those accounts comes with a password to manage, and each of those passwords is subject to a different set of rules about what constitutes a valid password. In the computer security field, those rules are called "password policy".
People can't memorize that many unique passwords, so they employ a lot of bad strategies to help out: using the same or similar passwords on all their accounts; creating passwords from regular words with certain letters substituted with other characters; or writing down all their passwords. I have over 200 accounts on the Internet and at one time or another, I've done all of these things. But they all seriously compromise the security of your accounts, defeating the purpose of the passwords. A password manager solved most of these issues for me. If you don't have one, I highly recommend it. I use the free version of Bitwarden.
My complaints now have more to do with how password policies themselves subvert security.
The purpose of a password is to protect access to something. And the purpose of a password policy is to ensure that passwords meet a minimum strength standard. This is all good.
A password policy should set a minimum standard, but not a maximum standard. In other words, a password policy should never make passwords weaker by imposing arbitrary limitations that reduce the number of possible combinations of characters in a password. To me, this should be obvious, but I've run into so many web sites that violate this seemingly self-evident principle.
There should be three rules added to every web software developer's philosophy regarding password policy:
- Encourage long passwords – Ideally, passwords wouldn't have a maximum length. But there are a few valid reasons to have them, including long password denial of service attacks, and password length limits imposed by encryption algorithms. If a maximum length must exist, then it should be long. 14 characters at a bare minimum, but even that is woefully inadequate in my opinion. I believe it should be 64 or more. As a point of comparison, the maximum password length on Microsoft Active Directory is 256 characters. If your encryption algorithm can't deal with sufficiently long passwords, then it's time to get a new one because not doing so is negligent. In this day of password managers, users have the ability to create and manage very long passwords made up of random characters. From a security standpoint, that's a very good thing. Don't be an obstacle to it!
- Allow any character – Policies should never disallow certain characters. Any character, including symbols and punctuation, should be allowed in a password. The more different types of characters allowed, the more combinations possible and the stronger the password system.
- Implement self-service password reset from the start – The lame excuse I've read for not doing these things is that they will increase the odds of a forgotten password and the need to reset it. Agreed. I can see how that would be the case. But the solution isn't to make your password system weaker. Instead implement a self-service password reset function from the very beginning. This will deflect most of the support calls you'd get from forgotten passwords and still preserve users' ability to use very strong passwords.
And the most important rule of all: When a user tries to set their password to some value that violates the policy, tell them what the damn violation is! Don't make them guess. In fact, at that point you should tell them all the policy rules so they don't have to discover them one-by-one through trial and error. Disclosing the password policy to users is not a security risk if your password policy is strong enough.
So get with it, developers!

There’s an interesting post on Ning Developer Blog on their choice to use PHP as the Ning platform client language.
At Tagged, we don’t roll the way Diego does at Ning, but it’s shocking how similar the thinking is. This post was related to the old dog: PHP templating systems vs. PHP as templating.
It reminds me of my biggest beef with working at Plaxo, which used C++ with clearsilver templating. Whenever I used Clearsilver, I kept thinking, “Well this is obviously designed by a bunch of C coders who think they know better.”
Coding in that joke of a templating system, was like coding with both hands tied behind your back. Having such restrictions did lead to a certain amount of creativity—introducing Ajax to Plaxo about a year before the term was coined, and maybe influencing things like Meebo—but I keep thinking how much the setup got in the way of programmers expressing their creativity. How long did my former company spend looking for C++ John Henrys, when a segmentation (like the way Ning does with Java core and PHP frontend) would have served as the steam-powered hammer?
The John Henrys can focus on what they’re good at instead of dying to prove that they can do HTML templating and everything else also. “Everything you can do I can do better…”
Diego is right, but my emphasis is different: PHP is a programming language.
And language is a vehicle for expression.
6 thoughts on “PHP as language”
Reading a little about Clearsilver made me pee blood.
What’s interesting is if you look at their list of who uses clearsilver you can trace the lineage of almost every product directly back to the eGroups team.
In other words, Clearsilver really says more about the immense talent and future positions of a certain group of people (eGroups->Plaxo, Bloglines, Google Groups, orkut) than about the superiority of templating system itself. The myopia is self- evident to anyone who has built websites in a scripting web language, even if those people can’t see it for themselves.
So when people talk about templating systems, I think of Clearsilver. It reminds me that very smart people can be very blinded by their ego, and unwillingness to respect the experiences of others.
We often forget that all this stuff is a means to an end, not an end in itself. Best is truly the enemy of good.
Thanks for sharing!
What is wrong with Clearsilver? I would like to hear your arguments not the flames.
Simply put, clearsilver is written by C programmers who think they know templating, but don’t. They read it in a book and never really spent any time working with a graphic or UI designer to figure out their real needs.
Still waiting to here what is actually wrong with clearsilver…

Virtual Robot - Creating a Two Robot Performance
Virtual Robot > Creating a Two Robot Performance
This page is now out-of-date. For modern multi-robot performances (after summer 2018) please see: Virtual_Robot_-_Multi-Robot_Performances.
Animating a performance for two robots to perform side by side, requires some careful planning if they need to be synchronised with an audio track or each other.
Performances for two robots can be triggered on the fly using programmed buttons on the touch screen interface. Embedding an input in the timeline of a performance is also possible. This means robots can trigger sequences on each other, and complete performances can be designed using the 'add input' feature.
Sychronising Two Robots
If two robots need to interact, work out which side or direction Robot #2 will be in relation to Robot #1. Once this is determined, animating and synchronising each robot in VR should be quite simple.
The following guide explains a simple method to synchronise animation between two robots, playing independent sequences.
Add audio for both Robots.
- Robot #1 Audio on track "audio #1".
- Robot #2 Audio on track "audio #2".
Animate Both Robots
Animate each robot's body, keeping Robot #1 in "motion #1" and Robot #2 in "motion #2".
This keeps animation for each Robot separate, and allows you to toggle the tracks on and off to check synchronisation of movements if required.
Once all the major movements are keyed and synchronised, duplicate this performance. Give the copy a sensible name (e.g. Welcome_Robot#2 , keeping the original file named as: Welcome_Robot#1)
Remove other Robot
Once you have my two files.
- Delete the animation and audio for Robot #1 from the performance for Robot #2.
- Delete the animation & audio for Robot #2 from the performance for Robot #1.
Now you should have two performance files with unique animation & audio, which is synchronised to the other robot. At this stage, continue working on each file, adding further animation detail, eye & lighting animation. Each sequence can then be deployed to each robot, and played as desired.
To play a sequence by triggering from within another sequence you will need to add an 'input' to the timeline you wish to trigger from.
- Toggle on the play sequence button (in the VR toolbox)
- Position the timeline marker where you wish to add your input
- Click the 'add single input' button (small pop up dialogue window will appear)
- Enter the following information
- Input Name: Play Sequence
- Value: sequenceName,0,0,1,3
The values in the Value string are: sequence name,offset,length,loops,player id
- sequence name - name of the file you wish to trigger
- offset - delay triggering in milliseconds
- length - not yet implemented (keep setting to 0)
- loops - number of times you wish sequence/performance to loop
- player id- determines where the sequence should be played. For a 2 robot setup this would typically be 3 as in our example.
Keep in mind the player id may be different depending on how your Robothespian's are setup.
In the example above we have added an input on the first frame of Robot#1's performance. This will trigger Robot#2's performance.
The robots trigger content on each other via their IP addresses. Robot 1 needs to be configured with the IP address for robot 2 and vice-versa.
Each robot will be assigned an IP by your own network or router. Please let Engineered Arts know the IP addresses of both robots so that they can configure the robots.
Please set your router to assign the same IP addresses each time. If the IP addresses are changed the robots will not be able to trigger each other.

SQLite VFS implementation guide lines with FOpen*
I am about to implement a custom VFS (virtual file system) for a Netburner embedded device (non windows) using FOpen, FRead, FWrite, FSeek, and FClose. I was surprised that i could not find a FOpen* version of the VFS available. It would make it a lot more portable to embedded devices.
I found some information on creating the VFS for SQLite here
http://sqlite.org/c3ref/vfs.html
but the information is very detailed and I have lots of other questions about the implementation.
I have some example VFS in the SQLite source code for Win, OS2, Linux but they don't have a lot of comments, only source code.
I could use the information provided in the link above and the examples to create my custom VFS but i'm sure that I would miss something if I did it that way.
My questions are:
Is there any more documentation about the SQLite VFS that I am missing? Maybe an implementation guide?
Is there an Fopen version of the SQLite VFS that is available?
Is there a unit testing code available to test my custom SQLite VFS once I have created it?
Suggestions, comments, experiences with implementing SQLite VFS that you would like to share.
If you run Linux on your embedded device why do you need to implement a new SQLite VFS?
its not Linux or Windows or OS2, its a modified version of http://www.freertos.org/ and does not include the Linux/windows libraries
I think you mean "implementation guide" not "implementation guild". A guild is an organization of craftsmen (sort of like a union, but more, um, medieval).
I don't have a good answer to your question, but I suspect fopen and friends cannot be used for sqlite, as there is no locking mechanism and the semantics, particularly relating to when data hits permanent storage, are not as nailed down as sqlite needs them to be.
Typo. As for the locking, you can set SQLITE_THREADSAFE=0 to remove the need for a locking mechanism or you can create your own using the sqlite3_file structure or so I am learning. I have started to create a VFS from the example ones for Win/Linux/OS2 but it is slow going without real documentation.
Did you notice that there is an additional source of documentation in the header file sqlite3.h? Also, Google code search is your friend.
Don't worry too much about missing things, this is what the test suite is for. Take a guess at the purpose of every method from their name, the documentation and the example implementations; go for a first-draft implementation; run the tests on your target platform; iterate until the bar is green. From a cursory reading of the interface doc that you quoted, here are some educated guesses:
int (*xOpen)(sqlite3_vfs*, const char *zName, sqlite3_file*,
int flags, int *pOutFlags);
int (*xDelete)(sqlite3_vfs*, const char *zName, int syncDir);
int (*xAccess)(sqlite3_vfs*, const char *zName, int flags, int *pResOut);
int (*xFullPathname)(sqlite3_vfs*, const char *zName, int nOut, char *zOut);
Those are your run-off-the-mill file management functions. You'll notice that xOpen() in turn returns a structure sqlite3_file, that has pointer methods of its own for reading and writing.
void *(*xDlOpen)(sqlite3_vfs*, const char *zFilename);
void (*xDlError)(sqlite3_vfs*, int nByte, char *zErrMsg);
void (*(*xDlSym)(sqlite3_vfs*,void*, const char *zSymbol))(void);
void (*xDlClose)(sqlite3_vfs*, void*);
Those are for shared libraries (see the dlopen() man page on Linux). In an embedded environment, you probably can leave these unimplemented (try setting these to NULL).
int (*xRandomness)(sqlite3_vfs*, int nByte, char *zOut);
You might have to implement a random number generator, if your OS' standard library doesn't provide one already. I suggest a linear feedback register, which is small yet good.
int (*xSleep)(sqlite3_vfs*, int microseconds);
int (*xCurrentTime)(sqlite3_vfs*, double*);
int (*xCurrentTimeInt64)(sqlite3_vfs*, sqlite3_int64*);
These are the time management functions, to hook up with your OS.
int (*xGetLastError)(sqlite3_vfs*, int, char *);
You can get away by always returning 0 here :-) See unixGetLastError in os_unix.c (thanks Google Code Search!)
Good luck!
One option is to use a memory based VFS then simply dump the memory to file when you are done. See: http://article.gmane.org/gmane.comp.db.sqlite.general/46450 for a memory based VFS that already supports serialization/deserialization.
The disadvantage is that you must manually write the file out for it to persist. If your application suddenly dies any intermediate changes to the DB will not be persisted.
Very enlightening link with an implementation of a VFS, but not sure we can use it as-is (see http://osdir.com/ml/sqlite-users/2013-06/msg00067.html)

when I tried to install lua-unbound it says
sudo apt install lua-unbound

Package lua-unbound is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

E: Package ‘lua-unbound’ has no installation candidate
The host definition Prosody is searching for is inside the file(s).
Normally all this is provided for automatically, but when doing funny stuff with Prosody, what can happen is that the path(s) is (are) messed up. Use
sudo prosodyctl about
to find out where the modules and the config live really (Config directory and plugin directories).
You should have something like:
Failed to restart prosody.service: Unit prosody.service is masked.
root@remote:/home/dali# systemctl unmask prosody
Then I do unmask
Systemctl unmask prosody
Then I’m again able to restart prosody. But session will stop to show the camera, so I jump into another pool of problems. Luckily I have VM snapshots to jump back at will.
Is there any updated install instructions or even better a prebuit VM with a working Jitsi setup? It’s kind of annoying to setup the system within a few minutes, then struggle for hours making it actually work.
Thank you for your help. It’s greatly appreciated.
For completeness sake: I received the same error message Prosody was unable to find lua-unbound [...]. I’m also on Ubuntu 20.04 which apparently does not provide the lua-unbound package. However, I still managed to install it via the luarocks client:

After applying the changes layed out in the handbook however I get an infinite loading reconnect prompt (“You’ve been disconnected”, Rejoin now button, etc.). I am not prompted to authenticate as I would have expected. There are no error logs in neither prosody, jicofo nor jvb log files.

How can I downgrade lua safely? Sorry for the beginner questions
I downgraded lua from 5.3 to 5.2. It was quite simple, since there seem to be downward compatibility in all lua libraries concerned. I just ran:
$ apt install lua5.2
$ apt remove lua5.3
Ubuntu then seems to switch seemlessly to lua5.2 … Before:
Then I went on to switch the config files to the secure-domain configs for prosody/jitsi meet/jicofo and I realized that I just copy and pasted the default domain name guest.jitsi-meet.example.com etc in 2 of them
So yea, it works now (with the lua downgrade), but I can’t tell if it was the lua downgrade responsible for it. Anyway, thank you very much for your input @emrah!
I have tried to downgrade prosody to 0.11 by using following command but in vain.
sudo dpkg -i prosody_0.11.4-1_amd64.deb
Pls let me know if this might be wrong command or not as the result was " dpkg: error: cannot access archive ‘prosody_0.11.4-1_amd64.deb’: No such file or directory". Thks in advance for your kind reply.
using dpkg directly to do changes is a great way to break your system if you are not very knowledgeable.
You can install package files using apt if you have to. Never force an update if apt warns you against it.
Why can’t you just follow the advice of people reporting success BTW, ie, using lua 5.2 ?

Performing File Restores (Full Recovery Model)
This topic is relevant only for databases that contain multiple files or filegroups under the full or bulk-load recovery model.
In a file restore, the goal is to restore one or more damaged files without restoring the whole database. All editions of SQL Server support restoring files when the database is offline (offline page restore). SQL Server 2005 Standard, SQL Server 2005 Express Edition, and SQL Server 2005 Workgroup, and later versions, support only offline restore, and restoring a file to the primary filegroup always requires that the database be offline. SQL Server 2005 Enterprise Edition and later versions use offline restore if the database is already offline.
In SQL Server 2005 Enterprise Edition and later versions, if the database is online during a file restore, the database remains online. Restoring and recovering a file while the database is online is called an online file restore.
These file restore scenarios are as follows:
Offline file restore
In an offline file restore, the database is offline while damaged files or filegroups are restored. At the end of the restore sequence, the database comes online.
Online file restore
In SQL Server 2005 Enterprise Edition and later versions, file restores are automatically performed online when the database is online. However, any filegroup in which a file is being restored is offline. After all the files in an offline filegroup are recovered, the filegroup is automatically brought online. For more information about online restores, see Performing Online Restores.
Only online filegroups can be queried or updated. An attempt to access a filegroup that is offline, including a filegroup that contains a file that is being restored or recovered, causes an error.
If the filegroup that is being restored is read/write, an unbroken chain of log backups must be applied after the last data or differential backup is restored. This brings the filegroup forward to the log records in the current active log records in the log file. The recovery point is typically near the end of log, but not necessarily.
If the filegroup that is being restored is read-only, usually applying log backups is unnecessary and is skipped. If the backup was taken after the file became read-only, that is the last backup to restore. Roll forward stops at the target point.
Restoring Files or Filegroups
To restore a damaged file or files from file backups and differential file backups
Create a tail-log backup of the active transaction log.
If you cannot do this because the log has been damaged, you must restore the whole database. For information about how to back up a transaction log, see Creating Transaction Log Backups.
For an offline file restore, you must always take a tail-log backup before the file restore. For an online file restore, you must always take the log backup after the file restore. This log backup is necessary to allow for the file to be recovered to a state consistent with the rest of the database.
Restore each damaged file from the most recent file backup of that file.
Restore the most recent differential file backup, if any, for each restored file.
Restore transaction log backups in sequence, starting with the backup that covers the oldest of the restored files and ending with the tail-log backup created in step 1.
You must restore the transaction log backups that were created after the file backups to bring the database to a consistent state. The transaction log backups can be rolled forward quickly, because only the changes that apply to the restored files are applied. Restoring individual files can be better than restoring the whole database, because undamaged files are not copied and then rolled forward. However, the whole chain of log backups still has to be read.
Recover the database.
File backups can be used to restore the database to an earlier point in time. To do this, you must restore a complete set of file backups, and then restore transaction log backups in sequence to reach a target point that is after the end of the most recent restored file backup. For more information about point-in-time recovery, see Restoring a Database to a Point Within a Backup.
To restore files and filegroups
Transact-SQL Restore Sequence for Offline File Restore (Full Recovery Model)
A file restore scenario consists of a single restore sequence that copies, rolls forward, and recovers the appropriate data.
The following Transact-SQL code shows the critical RESTORE options in a restore sequence for the file restore scenario. Syntax and details not relevant to this purpose are omitted.
The example shows an offline restore of two secondary files, A and B, with NORECOVERY. Next, two log backups are applied with NORECOVERY, followed with the tail-log backup, and this is restored with RECOVERY. The example starts by taking the file offline, for an offline file restore.
--Take the file offline. ALTER DATABASE database_name MODIFY FILE SET OFFLINE -- Back up the currently active transaction log. BACKUP LOG database_name TO <tail_log_backup> WITH NORECOVERY GO -- Restore the files. RESTORE DATABASE database_name FILE=<name> FROM <file_backup_of_file_A> WITH NORECOVERY RESTORE DATABASE database_name FILE=<name> ...... FROM <file_backup_of_file_B> WITH NORECOVERY -- Restore the log backups. RESTORE LOG database_name FROM <log_backup> WITH NORECOVERY RESTORE LOG database_name FROM <log_backup> WITH NORECOVERY RESTORE LOG database_name FROM <tail_log_backup> WITH RECOVERY

this tool is part of the itsutils tools collection.
source can be found at http://nah6.com/itsme/cvs-xdadevtools/itsutils/src/pdocread.cpp
This tool can be used to read and list various parts of m-systems DiskOnChip devices. The -d, -p, and -h options can be used to select a specific disk device. Only specifying -d will open that device directly. Specifying -d and -p, will open the device using the storage manager, and then us the partition specified with -p. To circumvent a problem with truncated device names in some WinCE versions, you can also specify a known open device handle, using -h.
Use "pdocread -l" to get a list of known devices, and open handles on your wince device.
The -n, -w, and -o options are used to select what access method is to be used. -n 0 will read from the binary partition number 0. -w will use the standard disk api to access the device, -o will access the One-time-programmable area of your DOC. when no access method is specified, the 'normal' TFFS partition will be accessed.
Be warned that the tffs API is not very stable, it causes device crashes, and on several devices it is only partially implemented.
currently pdocread is rather verbose, both on the commandprompt, and in a logfile on your wince device.
find the size of the various partitions:
C:\>pdocread -n 0 -t real nr of sectors: 4096 - 2.00Mbyte (0x200000) C:\>pdocread -n 1 -t real nr of sectors: 6144 - 3.00Mbyte (0x300000) C:\>pdocread -t real nr of sectors: 55296 - 27.00Mbyte (0x1b00000)
then copy the contents of these partitions to files, by entering the following commands on the command prompt:
pdocread -n 0 0 0x200000 docbdk0.raw pdocread -n 1 0 0x300000 docbdk1.raw pdocread 0 0x1b00000 docpart0.raw
- http://www.spv-developers.com/forum/showthread.php?p=8177 - a thread with a much more detailed explanation
often disk devices are only accessible via their kernel handle, the handles are listed in the output of =pdocread -l=, and accessed via =pdocread -h 0xHANDLEVALUE=
Usage: pdocread [options] start [ length [ filename ] ] when no length is specified, 512 bytes are assumed when no filename is specified, a hexdump is printed -t : find exact disk size -l : list all diskdevices -v : be verbose -s OFS : seek into source file ( for writing only ) -b SIZE: specify sectorsize to use when accessing disk -B SIZE: specify blocksize to use when accessing disk -G SIZE: specify blocksize to use when transfering over activesync -u PASSWD : unlock DOC device -S BK1x : specify alternate disksignature ( e.g. BIPO, BK1A .. BK1G ) Source: -d NAME : devicename or storename -p NAME : partitionname -h HANDLE : directly specify handle either specify -d and optionally -p, or specify -h Method: -n NUM : binarypartition number ( normal p if omitted ) -w : read via windows disk api -o : read OTP area if the filename is omitted, the data is hexdumped to stdout if no length is specified, 512 bytes are printed numbers can be specified as hex (ex: 0x8000) or decimal (ex: 32768)
the -w switch is useful for accessing non-diskonchip type flash devices.
the -S option is useful for accessing the rom on mDOC-H3 based devices. ( like the [HTC_Elf] or [HTC_Herald] )
the -G option is useful for accessing the rom on mDOC-G4 based devices.
note that on H3 devices the specified size to read must be exactly the size of the partition. on G4 and G3 devices the tffs api does not complain when specifying a very large size, it will just return the actual amount read.

"Configuring Datasources" page needs to be more descriptive
Description:
"Configuring Datasources" page [1] needs to contain information on
Tested databases and where to find db scripts
How to set up different databases for each component (Dashboard, Status Dashboard, Business Rules, Common Permission model etc)
[1] https://docs.wso2.com/display/SP400/Configuring+Datasources
Page [2] has some content related to the above topic. We need to properly group the information in both the pages.
[2] https://docs.wso2.com/display/SP400/Configuring+Database+Queries
Hi Tanya,
Thanks for informing the issue.
We have added parent page[3], also working on the content improvements as well.
[3] - https://docs.wso2.com/display/SP400/Working+with+Databases
To have common DB server for WSO2 products (for implementation of more than one product), better to use prefix for DBs (for example WSO2SP_DASHBOARD_DB) so less manual work to be done by admins on DB servers and on the scripts.
Hi etalaq,
Thanks for sharing your thought and experience regarding the Datasource naming conventions, actually you don't need to give any specific database name because our internal implementation referred the data source name, not the database name. Since we believe there won't be implication as you can create a database with the desired name.
Furthermore, regarding the data source name, we identified that there is an improvement where we can introduce common prefix as you mentioned, and we have created a new issue for track this task. https://github.com/wso2/product-sp/issues/473
Regarding the data source documentation task, we can close the issue as we have completed the all the necessary data source related information.
Hi, can you please provide where to find the database schema creation scripts for DASHBOARD_DB, PERMISSIONS_DB, etc? The documentation only provide queries.yml (i.e. carbon-analytics-common/components/permission-provider/org.wso2.carbon.analytics.permissions/src/main/resources/queries.yaml) but the queries alone are not useful when there is no schema to work on.
@luisguillo
For the 'PERMISSIONS_DB' and DASHBOARD_DB you don't need a database schema creation, it has the required table creation queries for PERMISSIONS_DB[1] and DASHBOARD_DB[2]. And we have tested these two features for the following database types:
H2, MySQL, Microsoft SQL Server, Oracle
Could you check our latest release pack?
https://github.com/wso2/product-sp/releases/tag/v4.2.0-M6
Also, please let us know any database type you are going to use for these two features?
FYI, currently we are working on the Postgres DB support for these two features.

@ksdperera Thanks. That info solved my problem. The binary 4.1.0 doesn't include the code for the creation of those schemas yet. I solved that manually.

Hi Ravi, <div><br></div><div>During discussions of API we considered several use cases and chose more specific case when member is specified by IP address. This makes API more low-level and covers case when user balances between existing VMs. To implement the use case of "elastic" members it will be needed additional layer, that communicates with Nova and Quantum core from one side and LBaaS API on the other. That solution is subject of future feature requests. </div>

I am not sure this question was answered earlier.
Pool Member API as defined <a href="http://wiki.openstack.org/Quantum/LBaaS/API_1.0" target="_blank">http://wiki.openstack.org/Quantum/LBaaS/API_1.0</a> =
is shown below for easy reference.
"address" parameter is IP address of VM that is expected to take up the loa=
In Openstack environment, application VMs' IP addresses are assigned dyna=
mically by Quantum IPAM. This API (Add Pool member) seems to be expectin=
g IP address. Admin configuring LB may not know the IP address. Moreover =
these application VMs are brought up dynamically upon the load and also bro=
ught down when load goes down. That is, pool members need to be added or r=
emoved dynamically. So, my question is who would be calling this API? It =
can't be through Horizon pages as user don't know the IP addresses.
To make client and GUI development easier, is it not good to take "VM grou=
p" instead of "address"? Internally, quantum can figure out the IP add=
resses of VMs in the VM group (by monitoring VM bring up/down events) and =
program the LB device dynamically with the IP addresses.
My understanding is that in openstack world, VM grouping is typically achi=
eved using "metadata" that is passed to 'nova boot'. "Role" metadata key=
is normally used to represent the role of VM. If that is indeed the case,=
"role" value can be taken as input to this API (Add Pool Member) function=
. For example, tenant can use VM group called "Web-Server-Group-10". W=
hen tenant brings up webserver VM that need to participate in taking up the=
load, it can be given "Web-Server-Group-10" as "role". Tenant can also=
configure the LB with "Web-Server-Group-10" as pool member. As long as =
quantum LB plugin has intelligence to enumerate the IP addresses of VMs tha=
t are brought up with "Web-Server-Group_10", it should be able to configur=
e load balancer device using appropriate LB drivers.
I am not sure whether this is a valid concern. If it is not, can somebody =

The Writer Sample is a demo for MWriter object. It illustrates how to capture a live source to the file or stream it to the network.
Below you can view a video explaining how to configure the live source and input/output stream properties, set up a preview, etc.:
- Live source video capture and network streaming with format conversion
- Delay or live source time shifting
- Advanced audio and video codecs management
- Closed captions capturing to file
- Preview control with deinterlacing
The Writer sample illustrates the use of MControls library to create a capture application.
To start capturing you need to:
- Select a source device.
- Initialize the device.
- Select a container format.
- Select audio and video codecs.
- Start to capture.
First, let’s look at the Device Settings panel, where you will find all of the properties for devices:
- MPlatform has an option to get a stream from any Source object (e.g MPlaylist, MFile, MMixer, etc.) that is currently active. It doesn't depend on which application Source object is working in. This logic is implemented in Extern Sink list. E.g. you can have MPlaylist runnning and obtain signal from it by selecting MPlaylist in Extern Sink
- You can set any properties for your audio or video devices and set its input format in Properties menu. To open this menu click Props button.
- To initialize the device you should click Init Device button. You'll get image from the device in the preview window.
- To select a different device click Close Device button. Select a new video or audio device and click Init Device again.
As a part of Device settings you have and option to select Delay enabled if you want to time shift your live source:
- Choose the amount in seconds. Note, that you have an option of Preview type to be delayed or live.
- Use a slider to seek thru the timeshifted stream.
- For more information, please consult our documentation at MDelay.
Format controls enable you to set format of audio and video select the required format in Video and Audio lists. Note, that if you want to capture file in a format that is different from your incoming format, you can choose before starting capturing.
Now, let’s take a look at Writer’s configuration panel:
1. To set the container format and audio and video codecs click the cell in every row and select the required property (e.g. format, audio and video). Note, that a list of encoders will differ depending on the type of container selected.
You can choose and configure container for streaming (select appropriate audio and video encoders) and type in streaming URL. It will work the same way as capturing file.
2. To configure additional parameters for formats and codecs you should double click on "format", "format::video" and "format::audio" cells to open attributes menu.
Next are the Capture control buttons:
- To start the capturing click Start Capture button.
- To pause capturing click Pause Capture button. You can select the duration of a pause in seconds.
- Click Stop Capture button to stop the capturing.
Preview panel has the following configurations:
- To enable or disable Video/Audio preview put a check mark.
- To control the volume for Audio preview use a slider.
- To adjust preview while maintaining aspect ratio check mark AR box.
- Use a Fullscreen option if necessary.
- To deinterlace your preview check mark Deinterlace box. Note, that it only affects the preview while the output is still interlaced. Useful when you need a high quality preview.
Note, that changes to the Audio and AR influence preview only, not the output stream.
There are two additional checkboxes below the Preview panel:
- If you want to add Character Generator elements (such as images, text and graphics) to your stream, check CG Enabled box and click CG Props button to setup Character Generator properties.
- Check mark Virtual Source box to enable the output of the sample to be available in the system as a DirectShow source filter, which makes it possible to use this stream with third-party applications such as the Flash Media Live Encoder. The name of the source in the list will be "Medialooks MLive Video".
Finally, you can monitor capture session’s statistics in the Writer’s status window.

Written By Jess Feldman
AI has taken 2023 by storm, from generative chatbots like ChatGPT to AI-generated art. But artificial intelligence and machine learning aren’t that new! Lighthouse Labs’ resident data expert, Simon Dawkins, demystifies AI and machine learning, including what you need to know to land a role as an in-demand AI engineer (or other roles that are crucial in working with AI). If you’re ready to jump into AI, learn how Lighthouse Labs’ Data Science Bootcamp is preparing students to graduate ready to use machine learning on the job.
Are there major differences between AI and Machine Learning?
Machine learning and AI are the natural outgrowth of everything data scientists have been doing with statistics and statistical modeling. We've been doing what could have been called AI for 60 years — it's just changing names and buzzwords!
Artificial intelligence (AI) is the broad concept of creating systems, machines, or algorithms that can do things that would typically be done by a human. Basically, AI is anything we think of as requiring intelligence being done by something artificial.
Machine learning is a subset of AI that specifically focuses on developing algorithms and statistical models. Machine learning is essentially math-based AI that trains computers specifically to learn from data, make predictions, and inform decisions based on data. Machine learning is based on the fundamentals of relatively simple math. What differentiates machine learning is that the math is done on such a large scale that it’s impossible for humans to do in a practical timeframe.
AI is the buzzword right now, but what are the actual roots of artificial intelligence?
The terms AI and machine learning are often used interchangeably. AI is the umbrella that machine learning falls under. All machine learning is AI. Almost all AI work these days is machine learning because it's almost all being done with computers. In the context of the tech world and the news that we’re reading, AI is machine learning.
ChatGPT and other generative AI are the popular terms in 2023, but we’ve been working on the foundational technology for many years. ChatGPT is a large language model, which is a type of neural network. Neural networks are part of deep learning, which falls under the umbrella of machine learning and AI. They're called neural networks because they were originally designed in an attempt to mimic the way we think neurons work in brain tissue. A lot of natural language processing (NLP) is done with neural networks.
Are machine learning models getting more powerful?
Machine learning functionality is getting more powerful but there aren’t great technological advances happening. We're not being held back by computer capability at the moment. The big push in AI right now is advancement of ideas, techniques, and algorithms and not technological advancement. OpenAI with ChatGPT, for example, was a new idea that people have been working on for a long time, as a new way of creating a language model and training it. Generative models are becoming cheap, easy, and accessible. Even though AI is making art these days, it is actually quite taxing to use, computation-wise.
We're moving toward a time that every company realizes they could make use of AI, given how cheap, accessible, and relatively easy it's getting. It’s not hard to imagine most companies using a simple AI model for their business:
For example: A cafe on the corner could look at customer flow in relation to weather, events, and traffic and how to better schedule their employees so they can save money by not scheduling too many people.
There's no reason not to utilize AI for your business! It’s a matter of companies realizing and being willing to implement it. AI-potential is basically unlimited. You don’t have to be a tech company with a bunch of advanced technical employees to use AI.
What is the difference between an AI/Machine Learning Engineer and a Data Scientist?
The difference between a machine learning researcher, a data scientist, and an AI/machine learning engineer is that the AI/machine learning engineer is the one taking the ideas, processes, and algorithms developed by the other tech roles and actually turning that into production-ready code to run on millions of devices.
The engineer jobs require a bit more experience and hands-on familiarity with programming. A company has to have quite a few analysts, data scientists, database administrators and data engineers before they need one AI/machine learning engineer.
Can a total beginner really become an AI Engineer through an immersive data science bootcamp?
It depends on the company. I see a lot of job descriptions that are confusingly defined. I tell my data bootcamp students that if it falls in the lines of data, apply! Many job descriptions are written by people who don’t actually know what they mean — they’re just using buzzwords and terms they were told to include. Data scientists and data analysts tend to be entry-level, while roles that include “engineer” require more programming experience.
Are today’s employers looking to hire data professionals who understand AI?
Without question, it is an expectation that data professionals have a clear understanding of machine learning.
That said, good data collection costs a company money — machine learning isn't magic, it's math! Part of your job as a data professional may be to talk your boss down from trying to use machine learning for everything.
On the job, will entry-level data professionals be using machine learning and AI? Or is this for more of a mid-level or senior-level role?
They should be ready to use machine learning right away. Simply put, if anyone spends a week or two learning Python and another week reading about machine learning, they can implement something with no trouble at all. Any of our Lighthouse Labs Data Science graduates leave the program knowing how to do machine learning or machine learning-related work. The question is if machine learning is the tool needed for the job because it’s more expensive.
What do you need to know about machine learning to begin to use or create AI?
It’s task dependent, so it would depend on what kind of machine learning is needed for the task, which will inform the kind of AI you'll build. If it's sentiment analysis of customer comments, then we'll need to get into natural language processing using neural networks. If it's image recognition, then we need to get into image tools.
For those already working in the data field, what is your recommendation on how to keep your skills relevant for AI?
It’s honestly not that hard to do! Unless you totally disconnect yourself from all news and social media, it's hard to avoid finding out about new things you might want to get familiar with. On a more technical level a lot of libraries, like Python libraries and other programming frameworks, will tell you when an update is needed. It takes five minutes a month to stay up-to-date on what’s happening.
Does Lighthouse Labs cover machine learning and AI in its Data Science curriculum?
Machine learning and AI are covered throughout the data science curriculum. We cover programming languages, database languages, and data visualization. In the third week, we start talking about statistical models at a simple level for predictions.
We show students how to use machine learning tools, the appropriate use of ChatGPT, how to write good queries, and how to prompt engineering for LLMs. Of course, as a student, there's temptation to use ChatGPT to do your work instead of learning on your own, so we try to teach them to strike that balance — we remind them that they’re paying to learn, not to pretend.
How do Lighthouse Labs students use machine learning and AI in the bootcamp?
Lighthouse Labs breaks the program into eight projects. There are two end-to-end projects: a week-long, midterm project and a two-week, Capstone project, both on their topic of choice.
We also have six other smaller projects usually completed over 1-3 days that drill down into a specific part of the process, such as: dealing with databases, accessing data, filtering it, combining it with other data, and statistical modeling. There is an entire project focused on dashboarding and creating good data communication. A couple other projects focus on specific areas of machine learning.
What is your advice for students who are enrolling in the Data Science program and interested in AI?
It’s the same advice I give to anyone considering a bootcamp:

I was quite surprised to read these nanopass ideas have been around for
so long. I might have heard of them about half a decade ago at the most.
I actually thought they were pretty recent... always learning...
OK, after reading your comment and skimming through the code it might be
that my problem is not being totally aware of the details of nanopass
compilation and therefore looking to the code and instead of being able
to abstract away portions of the code for different functions, just
seeing a huge blob of incomprehensible scheme with absolutely no comments.

I guess a long comment describing some of this in the beginning of the
file would certainly be useful. In any case, as someone who dealt with a
lot of code and most of it development tools related I have never seen
anything like this. It would certainly be a lot clearer if each of the
passes had their own file. For example, in GCC all passes have their own
file and they are amazingly well commented. So if you open a file like
the register renaming pass
it is close to 2000 lines of C, it's pretty readable (assuming you know
how GCC IR works, of course). Also, you know this code is doing a
specific job, instead of doing 'all jobs', as in the case of the
cpnanopass file. But given Matthew's other message, I don't want this to
come across as me whining about the state of Chez but instead a call for
action to improve the situation. :)

Scheme code is usually denser than C, therefore I am certainly less

Not able to load js files from local where as CDN path working fine in Dojo 2 application. Once included custom JavaScript files using script tag in index.html. But in browser it shows the error 404 file not found.
Please suggest as i need these for my Dojo 2 application.
This is my how i am using script tag to include
script src="assets/js/jquery.js" type="text/javascript"
Do you have the jquery.js file in a assets/js folder ?
yes i do have it and need to load it.
Any suggestions please. unable to include local library files other than CDN in Dojo 2 project
Currently, the Dojo 2 build does not copy external assets to the build directory, but we are working on a way of specifying such assets in the .dojorc config (index.html is not/will not be scanned for assets). In the meantime, another means of delivering static assets will be required (for example, configuring the assets/ path at the server level).
Thank you can you please share the code of how to for this part of ur comments. 'another means of delivering static assets will be required (for example, configuring the assets/ path at the server level)'
Any suggestions please. As i need to use the icons and js files
Assuming you are using the dojo 2 cli you need to move your assets folder into the root of you application, this is in the dojo 2 build docs:
While most assets will be imported by modules in the src/ directory and therefore handled by the main build pipeline, it is often necessary to serve static assets or include assets in the HTML file itself (e.g., the favicon).
Static assets can be added to an assets/ directory at the project root. At build time, these assets are copied as-is without file hashing to output/{mode}/assets, and can be accessed using the absolute /assets/ path. For example, if users need access to a static terms of service document named terms.pdf, that file would added to assets/terms.pdf and accessed via the URL /assets/terms.pdf.
The build also parses src/index.html for CSS, JavaScript, and image assets, hashing them and including them in the output/{mode}/ directory. For example, it is common for applications to display a favicon in the URL bar. If the favicon is named favicon.ico, it can be added to the src/ directory and included in src/index.html with . The build will then hash the file and copy it to output/{mode}/favicon.[hash].ico.
But another option is to add a new npm command "move-assets": "cp -R ./src/assets ./output/dist/assets" to you package config
"scripts": {
"start": "dojo build --mode dev --watch memory --serve",
"build": "dojo build --mode dist && npm run move-assets && npm run move-assets",
"move-assets": "cp -R ./src/assets ./output/dist/assets"
}
This will move your assets into the build output folder ./output/dist

For nearly all software products, there is some level of learning that must occur to achieve a successful user experience. This learning typically occurs by two primary mechanisms within the product. The first is through the inherent learnability built into the product design. The second is through the content quality and information design. These concepts of usability and learnability are intrinsically related, and must work in concert to ensure a positive user experience.
To provide a standard way to assess product learnability, the Simulation UX / LX Team has developed a set of Learnability Heuristics in the same mold as Nielsen’s Usability Heuristics (http://www.useit.com/papers/heuristic/heuristic_list.html):
- Good content practices: Content should adhere to good writing and video practices. Bad grammar and spelling, passive voice, use of the past- or future- tense, and hopelessly long sentences seriously degrade the learning experience.
- Searchability: Users should be able to find the information they need.
- Build-in learnability: The UI design should promote targeted understanding through the association of the discrete steps needed to perform a specific task. The user should not have to be a product expert to be able to accomplish most goals, but rather be able to leverage a discrete body of knowledge.
- Process discoverability: The product design and the learning content should work together to guide the user through complicated processes that involve multiple tasks.
- Rapid recollection: The design should promote retention and easy relearning after a break from the product. It should facilitate recognition and rapid re-association with previously learned tasks.
- Good information design: Logically group related topics together. Within topics, organize content according to the inverted pyramid model. Start with the main point in the topic, and provide supporting content in order of decreasing importance through the topic. Remember that most readers tend to move on to the next topic if they do not find what they are looking for very quickly.
- Action oriented: Content should emphasize both real tasks and what defines successful completion. Instead of focusing on individual user interface elements (the “atomic” level of the product), focus holistically on the product, and communicate actual tasks that the user will perform. Round out the description by describing (or showing) what a successful implementation of the task should look like.
- Delivery method: The framework and output format should convey the content effectively and not interfere with the user experience. A clumsy delivery method can greatly impair the effectiveness of even the best content. An obvious example is a 600 page printed book verses a topic-based help system with search capability delivered electronically on multiple platforms.
- Motivation: The user should understand the context of the UI element and how the associated learning content helps them reach their goals. The content should effectively convey the exigency (the "why") and the goal (purpose).
- Error avoidance and recovery: The content and the design should help the user to avoid known common issues. Because some problems are inevitable, the content should also describe how to resolve known potential pitfalls.
- User-centric: The content should relate to the user's world and communicate in the user's vocabulary. Product jargon is unavoidable, so at least relate the product vocabulary to the user’s world. If a “gizmo” in the user’s world is called a “widget” in the product, make this connection very clear.
To help achieve the standards described by these heuristics, we developed a series of usability and learning content development guidelines:
Design for Learnability
- Use clear and descriptive UI titles
- Design logical, self-evident workflows
- Help the user avoid mistakes
- Provide easily identifiable starting points
- Create a clear path to Help
Search and Accessibility
- Use consistent terminology in UI and Help
- Include synonymous terminology
- Include links to related content
- Create a well-designed TOC
Information and Content Design
- Describe the process
- Include a range of application types
- Describe success
- Lead with primary point
Communication with the User
- Use "real world" language
- State objectives
- Describe error correction
Good Content Practices
- Apply minimalist written content principles
- Use video best-practices
It is important to consider learnability as part of the user experience from the earliest design stages. Even the most simplistic “apps”, despite their lack of help, contain built-in learnability. For more complicated products, this inherent learnability is still vital, but must be coupled with dedicated learning content to ensure a delightful user experience. These heuristics provide a means for assessing software product learnability.

To the best of my knowledge, at least the ray tracing should not cause any delay: It's implementation is very fast, and the engine runs dozens of ray traces at any frame anyway.drwbns wrote:I was wondering if anyone else is getting a firing "lag". Like it's taking a long time to compute a ray trace or something. It seems the further away the shot is fired, the more the lag time. Anyone?
When you try the same shot a second time, is the second shot equally delayed as the first? If not so, it's possibly a matter of initializing additional resources like sounds and textures. (Most textures including sprites are loaded in advance though, so maybe it's the sound driver that needs extra time to initialize a new sound before it's first played.)
Unfortunately, it's difficult to tell what causes the lag, but it still looks to me like some kind of resource bottleneck.
When you continue to run around in the TechDemo island, does the lag still occur?
Does it also occur when you leave the building and enter the open space without firing a shot?
Then, what system specs do you have? (Type and Speed of CPU, main RAM, GPU RAM, ...)
This really looks like some kind of RAM was depleted and the system resorted to swapping things around, e.g. from GPU RAM to main RAM, or main RAM to hard-disk, etc. (you can tell the latter if a lot of hard-disk activity is involved at the same time, or much better of course, if you use

It helps promote modularization of code, code reuse, efficient memory usage, and reduced disk space. So the operating system and the programs load faster, run faster, and take less disk space on the computer. A dynamic link library is a shared program module with ordered code, methods, functions, enums and structures that may be dynamically called by an executing program during run time. A DLL usually has a file extension ending in .dll.
You should check if there are errors or bad sectors in your RAM or hard disk. This is because a faulty storage device also can trigger the Isdone.dll error. It seems that I was trying to run a supplementary program without installing the main program itself. The main program itself apparently carries all the necessary DLL files. System files are often vulnerable to errors and corruption, especially after resetting Windows 10 or dealing with a malicious application.
- Right-click on the Start Menu button, and choose Command Prompt .
- It consists of variables, resources, and classes that can be used, shared, and accessed by other programs simultaneously.
- This is because they could be infected with malware, adware, or Trojans.
- Nearly all files on Windows possess this permission, including .xml files in the system32 folder.
Kernel32.dll files missingSeveral users reported that Kernel32.dll is missing on their PC. DLL files, also called Dynamic Link Libraries, contain a collection of executable functions and information that can be used by various Windows programs. Instead, it is loaded and used by a program executable , so you should not try to run them on their own. The purpose of doing this to analyze files requires an analyst to first have dynamic monitoring tools running and ready to go. It has a set of functions that are needed to run many apps of the system. To observe the contents of a document and change its parameters, you need to use special programs designed for decompiling, editing library code.
Managing DLL files more tips here, deployment, and ease of use for the end user
I am not talking about a virtual machine but compatibility modes in the properties of the executable 16/32 bits. At times, a software may be designed to work on an earlier or specific version of Windows that is different than the current Windows 10 your system is running. You can approach the DLL missing error for these software from two angles. First, you may run the application that bring up the DLL error in compatibility mode. To do this, find the executable file, right click and select properties.
She couldn’t tell she was on a new version of Windows. Registering 32-bit DLL file on 64-bit WindowsYou can also use PowerShell with the same commands to register DLL or OCX files. If your troubles started over the summer, reinstall the original CRT package, available via Microsoft Download Center. Registry Cleaner is a powerful utility that can clean unnecessary files, fix registry problems, find out the causes of slow PC operation and eliminate them.
What are dll files & how to open them – Dynamic Link Library File
On the bright side, I haven’t formatted since winxp pro became public…so this might do some good. Congratulations, you have successfully unregistered and removed unwanted dll file. If you don’t know why you need to unregister dll file before removing it, I will tell you. So, first of all you will need to locate a dll file that you want to unregister and remove. Click on the Start button and in the search field type the name of unwanted dll file. Now you should see this dll file, save the path of this file by right clicking on it and selecting file location, and copying the path in address bar.
This can be true no matter the cause of the problem. You can do this using File-Open in the top panel. Next, the file is edited at the discretion of the user, it is compiled using the Compile Script option, only then the file is saved. One of the main points of a DLL or executable is to hide the code , you’re not meant to be just “open it” and read the source. If your decompile attempts don’t work then you’re probably just out of luck.
Since DLLs are essentially the same as EXEs, the choice of which to produce as part of the linking process is for clarity, since it is possible to export functions and data from either. Another benefit of modularity is the use of generic interfaces for plug-ins. This concept of dynamic extensibility is taken to the extreme with the Component Object Model, the underpinnings of ActiveX. This article is about the OS/2 and Windows implementation. For dynamic linking of libraries in general, see Dynamic linker.

A few points I'd mention here:
The 'Post Notice' on your answer is designed to be a friendlier way to encourage high quality answers, and help community members understand how to improve existing answers. I would suggest the terms 'warning' or 'threat of deletion' are a bit too strong - I think the comment in it about Editing and Deletion is more to explain to newer users how the site works. It can be used as a preliminary measure ahead of content deletion, where appropriate.
In terms of appropriateness, I'd agree that the Answer in question is rather low quality in terms of its evidential basis. You've done a great job providing texts to explain your thought process, but the 'feel' of the answer reminds me of pearls on a string, where it's only the arrangement of the passages that gives the appearance of a hermeneutical argument, rather than a clear exegetical case for your conclusions.
In terms of consistency, I'd say that your answer is on a par with one other to that question in terms of the reasoning and content - it's detailed enough and so I'd suggest that 'citation needed' would be more appropriate. For this reason I've changed the notice over, and added a similar notice to the similar answer.
I appreciate you flagging the inconsistency here, but I think it's worth bearing in mind that as moderators we often are not reading every post in detail, and have to choose where to spend our time. Just because we add a post notice to one Answer does not mean that we have read and weighed every other Answer to that same Question. A post notice is a good indication that one of us has scrutinized it, but the lack of a post notice doesn't tell you whether we've read it or not. If I felt like I always had to read every Answer to a Question before placing a notice, I'd probably use them far less than I should!
Better Questions Attract Better Answers
Lastly, I don't necessarily think this at its root a problem with the Answers so much as it is with the Question. To me, this event is a symptom of a poor question, which is attracting opinion-based answers. This is a community site, and so there is sometimes that awkward balance where some users think 'this is answerable based on information in the text' and others view those as opinion-based answers.
The question is asking about information that's not explained or hinted at anywhere in the text of Matthew - we've got three different answers with different ideas that only have vague connections with other Gospel passages. I think perhaps in this case the quality of the answers is indicating issues with the Question.
If I were a user I'd be casting a vote to Close that Question as Opinion-Based, and then other people would get a vote. However, as a Moderator if I VTC, it will be closed instantly. As Moderators we do often try to give community members the benefit of the doubt and avoid Closing questions single-handedly where the community is not flagging content issues.

What passwords are stored in Microsoft Windows? How can I know what password are saved in computer?
Yes, they are stored hashed within files in the
c:\Windows\System32\Config\ directory. You will need the
system files. However, a backup of these files may be stored in the Windows repair folder at
SAM contains the hashed passwords, however they are encrypted using the boot key within the
If Windows is running and you need access to the locked files in the
Config folder (for example you know the files in
Repair are out of date), you can extract these files using regedit.
C:\>reg.exe save HKLM\SAM sam
The operation completed successfully
C:\>reg.exe save HKLM\SYSTEM sys
The operation completed successfully
An alternative is to use a tools such as Pwdump which can extract the hashes stored within the
system files directly without the need to use regedit or manual decryption of the SAM using the boot key.
Windows passwords may also be cached in memory. Windows Credentials Editor can extract these values in plain text from the Windows Digest Authentication package.
WCE v1.3beta (Windows Credentials Editor) - (c) 2010,2011,2012 Amplia Security - by Hernan Ochoa (hernan@ampliasecurity com)
Use -h for help.
You will need local administrator access to do all of the above, unless you can mount the partition from another machine to directly access the files in the first case.
Network passwords are stored inside Windows Vault/Credential Manager:
Tools such as Windows Vault Password Decryptor can extract and decrypt these.
To access the windows passwords, you'll need both the SAM and SYSTEM file from C:/WINDOWS/SYSTEM32/config
On a Linux Distro, like Kali-linux, you can then use the command "bkhive SYSTEM bootkey" to get the bootkey from the system file. Then, use the command "samdump2 SAM bootkey > samdump.txt" to get the hash dump from the SAM file.
If you open the file, you'll see lines similar to below:
This means the admin account's NTLM password is "44bf0244f032ca8baaddda0fa9328bf8".
If you see something like:
This means the PC has LM hashes enabled. In this case, the LM hash is "37035b1c4ae2b0c54a15db05d307b01b". LM hashes are easy to crack, they have the strength of a 7 character password (look it up on wikipedia to find out why).
The SAM and SYSTEM file generally are obtained when the PC is powered off. However, there is a technique to get the files when the PC is powered on, using shadow volume copy, which is available in modern versions of windows. Essentially, this allows you to take a back up of the running system, and you can extract the SAM and SYSTEM file from that backup. Google is your friend, there are many articles explaining this technique in detail.
Yes, Widnows saves users' passwords in 3 files:
Windows\System32\Config\SAMfile (without extension).
Windows\System32\Config\SAM.sav: it is a copy of the first one
Windows\System32\Config\SAM.logA transaction log of changes.
To access these files, run
Start/CMD and type
%SystemRoot%then choose the subfolder
These files can not be read, deleted or modified in any way by the user.
These files are diretctly used and read from this windows registry key:
All local user account passwords are stored inside windows. They are located inside
C:\windows\system32\config\SAM If the computer is used to log into a domain then that username/password are also stored so it's possible to log into the computer when not connected to the domain.
As for seeing which passwords are currently stored on a computer you can use a program such as Cain and Abel to see the different users and their corresponding hashed passwords. Cain and Abel will also allow you to attempt to crack the passwords if you have enough spare time.

Capacity Planning for your Virtual Data Center and Cloud – Part 2
In this 2nd part of my blog on capacity planning, we shall look at the steps to implementing Capacity Management for your Virtual Data Center and Cloud.
Many IT organizations have used virtualization and cloud to paint a visionary picture of agile, on-demand and cost-efficient IT that will meet changing business requirements for their business users. While this is possible, many IT organizations by now should have realized that at the heart of this capability is capacity management. Put simply, this is what allows IT to always have adequate compute, storage and network resources at a minimum possible cost to the company. Traditionally, application owners would size for usage peaks plus buffers while IT administrators would pile some more buffers and contingencies on top of these. We need to move away from this practice of “Just in Case” capacity planning – which is not optimal and results in underutilization and wastage – and move towards a “Just In Time and Just Enough” model for capacity planning where the right amount of resources are available at the right time and, most importantly, the right cost.
In today’s highly virtualized or “cloudified” IT environment, running IT has a lot in common with running a factory. For example, both need to ensure that their stock inventory is minimized to reduce costs and yet have enough available surplus to meet the production plan. They also need to be able to quickly reshuffle and redeploy resources and inventory should there be changes to production demands. In a factory, this role is titled ‘Production Planner’. In IT or ITIL framework, we refer the role as ‘Capacity Manager’.
One of the first steps to implementing Capacity Management will require assigning a Capacity Manager (sometimes it is also referred to as Capacity Planner) who will oversee the capacity planning and management of virtual/cloud resources. Some of the key activities the Capacity Manager will perform are:
- Getting forecast figures from the business units to understand project pipelines and future demands on virtual/cloud resources
- Baseline current capacity and BAU demands; and develop a hardware and software procurement plan and budget based on forecasts
- Set capacity thresholds and monitor usage to identify wastage or to initiate hardware/software acquisition to add capacity when usage hits the upper thresholds
- Regularly review forecasts and actual demand. Readjust procurement plan and budgets as business requirements change
- Through monitoring, reclaim or balance workloads and resources as appropriate
The next thing we must establish is the capacity management process, which addresses the activities listed above. A typical high level process flow is shown below:
As part of the process deployment, policies, rules, metrics and KPIs need to be defined so that appropriate monitors and reports can be implemented.
We will continue our discussion in my next blog!

Website Transactions in MySQL Database
Good Day,
I'm currently designing database structure for a website of mine. I need community assistance in one aspect only as I never did something similar.
Website will include three types of the payments:
Internal payments (Escrow kind payments). User can send payment to another user.
Deposits. Users add fund to their accounts.
Withdrawal. User can request a withdrawal. Money will be sent to their bank/PayPal account.
Basically, I need some tips to get the best design possible.
Here's what I'm thinking about:
deposits - this table will store info about deposits
deposits_data - this table will store info about deposit transaction (ex. data returned by PayPal IPN)
payments - table to store internal payments
withdrawals - table to store info about withdrawal request
transactions - table to store info about ALL transactions (with ENUM() field called type with following values possible: internal, deposit, withdrawal)
Please note that I have already a table logs to store every user action.
Unfortunately, I feel that my design approch is not the best possible in this aspect. Can you share some ideas/tips?
PS. Can I use a name "escrow" for internal payments or should I choose different name?
Edit
DEPOSITS, PAYMENTS and WITHDRAWALS tables store specific transaction details. TRANSACTIONS table stores only limited info - it's a kind of logs table - with a details field (which contains a text to display in user log section, ex: "User 1 sent you a payment for something")/
Of course I have users tables, etc.
i have same kind of database design scenario can you please tell me what kind of internal payment you are storing in payments table so that it can help me design my database.Thanks
Can I use a name "escrow" for internal
payments or should I choose different
name?
Escrow has a specfic financial/legal meaning, which is different from how you seem to mean it: "a written agreement (or property or money) delivered to a third party or put in trust by one party to a contract to be returned after fulfillment of some condition" (source)
So choosing a different name seems like a good idea.
As for design, what data will DEPOSITS, PAYMENTS and WITHDRAWALS store which TRANSACTIONS won't? Also, you need an ACCOUNTS table. Or are you planning to just use your existing USERS table (I presume you have such a thing)? You probably ought to have something for external parties, even if you only intend to support PayPal for the time being.
I'd like to post a comment but it was a bit too long so I edited my question. Thanks for your answer!

Allow ion-searchbar input to automatically receive focus
Short description of the problem:
In my use case I have the ion-searchbar hidden to preserve screen space. When the user taps the search button in the navbar the ion-searchbar is displayed. The user has to then tap the input in the ion-searchbar for it to receive focus and open the keyboard.
What behavior are you expecting?
It would be a better user experience if simply tapping the search button displayed the ion-searchbar, set the focus to it's input, and opened the keyboard.
Basically all we need is the ability to add a local variable "#input" to the ion-searchbar component which we could then use to set focus and open the keyboard as done in Mike Hartington's blog post!
http://mhartington.io/post/setting-input-focus/
Ionic version 2 beta 3.
So I think this is something that should be handled by the addition of the 3rd type of searchbar (number 1 in this image):
There was an open issue to do this but I don't think it got moved here. Will keep this one open for it.
Yes, this is something really necessary!
i think even better would be support for the autofocus attribute
For those who come to this post, simple workaround about creating a [focuser] directive
import {Directive, Renderer, ElementRef} from "angular2/core";
@Directive({
selector : '[focuser]'
})
export default class Focuser {
constructor(public renderer: Renderer, public elementRef: ElementRef) {}
ngOnInit() {
var searchInput = this.elementRef.nativeElement.querySelector('input');
setTimeout(() => {
//delay required or ionic styling gets finicky
this.renderer.invokeElementMethod(searchInput, 'focus', []);
}, 0);
}
}```
```<ion-searchbar
[focuser] placeholder="Enter Your Address"></ion-searchbar>```
Make sure to add Focuser to your directives then bingo
@SP1966 Hey! Are you still experiencing this issue or are you using the workaround above? As you can see this issue is marked for beta.12, so at this point you can expect it to be fixed in that release. Thanks!
@jgw96 I was using the latest beta last night and still had this problem (unless I missed something in the docs)
@kentongray I expected you would still be having a problem. Like i said earlier this issue is marked for beta.12 at this point, so you can expect a fix in that release! Until then, i would recommend continuing to use your workaround. Thanks again!
@jgw96 I gave your idea a try and it's not working. I have the searchbar hidden initially and toggle it into view when needed. If I set it toggled into the view as it's initial state then it works great, but when it's toggled in after the page loads it's a no go.
Thanks for the reply though! I'm looking forward to each new beta!!
@SP1966 Hmmm sorry it didnt work! We moved this down to the beta.7 milestone now, so you can expect a fix even sooner now! Thanks for using Ionic!
@jgw96 @brandyscarney It looks like I'm trying to solve this exact issue. Has there been any progress to rolling this into a beta release? Is there anything I could do to help out?
Hey @bryancordrey, sorry I know this issue has been passed around a bit. We reorganize the issues sometimes and things end up getting bumped around. It is currently set for beta 9 but as you can see this is subject to change. I haven't had any time to look into this but I will try to look into it once we release beta 8.
If anyone wants to submit a PR for any part of it, that would be helpful to getting this in faster. I've added some steps to our contributing doc if anyone is interested: https://github.com/driftyco/ionic/blob/2.0/CONTRIBUTING.md#creating-a-pull-request
Thanks. :smile:
For some more background here, on touch devices it is difficult to programmatically focus an element. Sounds like an easy task yes, and on desktop it works fine, but to set focus on an input element and expect the keyboard to come up, the element.focus() command must be called within a user's touch event's callstack.
@adamdbradley as @brandyscarney mentioned this is best handled in the search bar that appears in the header bar. If that's the case it's likely that it appears when a new view has just been pushed i.e. the user tapped a link to open some sort of "search" view? Perhaps that is something that can be tapped into?

Interestingly with beta10 on android on a Samsung s7 with all updates search does automatically get focus for me. In my app I have a button in the background bar that shows or hides the search bar embedded in the navbar on demand. When I click to show the search bar on android it shows, receives focus and the keyboard opens, just like native it's great.
iOS does not do this unfortunately but it would be great if it did!

Besides autofocus, ion-searchbar should have an option to always show the back button.
Like the Whatsapp behavior on his search contact modal.
^ +1!!! Instagram does the same thing with their search feature.
These are the two things my search feature really needs too.
so what's the story on this now? any support? beta 11 seems to have broken the work around on ios
@kentongray this solutions seems to not work on iOS.. when I add this directive and open the view with it, I get a blank screen. If I click in the screen the view appears but the focus doesn't work.
I don't know if I'm missing something, but if I remove the directive the view open normally...
@cleever @maxtuzz

can you open an different issue for that? thanks!
@manucorporat sure!

Any fix for this issue?
So now that Ionic2 is out of beta, what's the new target milestone for solving this one? I saw in the code that there is a setFocus method, but it doesn't actually do anything afaict? I haven't tried with ionic run android, but certainly nothing happens in ionic serve browser context.
Hello everyone! Thanks for the feature request. I'm going to move this issue over to our internal list of feature requests for evaluation. We are continually prioritizing all requests that we receive with outstanding issues. We are extremely grateful for your feedback, but it may not always be our next priority. I'll copy the issue back to this repository when we have begun implementation. Thanks!

As we near the 12 month anniversary of this request, sorry to be rude, but why does this come to mind?

Hi,
I'am new in ionic , please how to make a searchbar like the one @SP1966 is talking here ?
thanks in advance

Sometimes a product dies because the maintainers don't value their users' feedback and suggestions.
Hello all! While we have locked this issue this is still a feature that we are considering adding to ionic in the future. We work on a prioritized queue and are currently working on other issues. However, the awesome thing about open source is that anyone can submit a PR to add this feature, and, if you would be interested in doing this we'd be happy to work with you. Thanks for using Ionic everyone!

Yes, you're correct. Thanks for noting that.

If the unsigned multiply operation is expensive, in terms of
processing time, (e.g. the processor has NO muliply instruction at
all) it is pretty easy to verify. Basically, the *algorithm* is more
efficient because we're trading one multiplication for a few additions
and subtractions, but the break-even point in the real world, on real
processors, depends on the relative costs of those operations and the
actual size of the multiplicands relative to the "native" size for the
machine. If we're doing multiplies of two 64-bit numbers on a 68HC11,
I think it's clear that it's going to come out ahead of the classic
O(n^2) implementation. If we're just multiplying two 16-bit numbers,
the timing probably depends more heavily on the details of the actual
implementation. As I mentioned, I haven't done the full analysis of
the cycle counts for that processor -- just a "back of the envelope"
calculation that seems to indicate that it's at least worth looking
Quote:>It would be necessary to
>check for negative operands, convert them to positive and calculate the

>mixed signed and unsigned addition to complete the 2^n term.
The middle term does need a signed multiply, but this is not too
difficult to effect, just as you've mentioned. As for mixed signed
and unsigned addition, they all look the same if we're dealing with
two's complement numbers. OTOH, if we're dealing with signed
magnitude numbers (like Knuth's pedagogical MIX processor) then it's
trivial to take the absolute value of a number, and we still don't
have any particular problem.
Quote:>Even with a signed multiply instruction, the U1-U0 and V0-V1 terms are
>not representable as an n-bit signed integer: at least one more bit is
>needed for the sign, since the difference terms may range between
>-(2^n - 1) and +(2^n - 1).
Actually exactly one "scratch" bit is needed, but more may be used for
convenience. First, do the first subtraction and take the absolute
value and store the original sign in the scratch bit location. Do the
second subtraction and take its absolute value, and XOR this sign with
the scratch bit. Do an unsigned multiply and negate the result if the
scratch bit is set. The scratch bit does not have to be initialized
to any particular value, and it doesn't matter which sign is
represented by a 1 as long as both tests are consistent and use the
On machines like the 68HC11, which don't have a bit complement
instruction, it might be handier to burn up a whole byte-wide register
-- in that case, you'd just zero the reg and increment it for each
time you got, say, a negative number. After doing the multiply, if
the low bit of the scratch byte is one, complement the result of the
multiplication. Again, while the algorithm is more efficient, the
details of the particular machine have a great deal to do with whether
it's really more practical in a given situation. Thanks for the great

Mock dynamic require in Node with Jest
Given an npm package that needs to dynamically load a dependency from the root of the parent/referencing package, and that location isn't known until runtime, it has to do a dynamic require:
// config-fetcher.js
const path = require('path');
const getRunningProjectRoot = require('./get-running-project-root');
module.exports = filename =>
require(path.resolve(getRunningProjectRoot(), filename));
(There's no guarantee that the module will be in node_modules. It could be symlinked or loaded globally. So it can't use a static require.)
This is simplified from the real code, so unless you know of a way to require files non-dynamically relative to the running project root, this has to be this way.
Now, to test this, I'd prefer not to depend on any file that's actually on disk. However, Jest seemingly won't let you mock a nonexistent file. So if I try this:
const mockFileContents = {};
jest.mock('/absolute/filename.blah', () => mockFileContents);
// in preparation for wanting to do this:
const result = require('./config-fetcher')('/absolute/filename.blah');
expect(result).toBe(mockFileContents);
then I get an error from jest-resolve, with file Resolver.resolveModule throwing Error: Cannot find module '/absolute/filename.blah'.
I need to test some of the functionality of this dynamic requiring module, as it handles some cases of relative paths vs. absolute paths, and allows you to specify a special path through a Symbol, with one being for example applicationRoot, so the module config-fetcher does the hard work instead of the caller.
Could anyone offer guidance on how to test this module, or how to restructure so dynamic requires aren't needed or they are easier to test?
You can pass { virtual: true } as options in jest.mock to mock a module that does not exist:
const { myFunc } = require('does not exist');
jest.mock('does not exist',
() => ({
myFunc: () => 'hello'
}),
{ virtual: true }
);
test('mock file that does not exist', () => {
expect(myFunc()).toBe('hello'); // Success!
});
Details
Jest completely takes over the require system for the code under test.
It has its own module cache and keeps track of module mocks.
As part of this system, Jest allows you to create mocks for modules that do not actually exist.
You can pass options as the third parameter to jest.mock. Currently the only option is virtual, and if it is true then Jest will simply add the result of calling the module factory function to the module cache and return it whenever it is required in the code under test.

Get Gpu Name Tensorflow And Pytorch With Code Examples
In this session, we will try our hand at solving the Get Gpu Name Tensorflow And Pytorch puzzle by using the computer language. The following piece of code will demonstrate this point.
# tensorflow from tensorflow.python.client import device_lib devices_tf = device_lib.list_local_devices() devices_tf = print(devices) # pytorch import torch devices_torch = torch.cuda.get_device_name() print(devices_torch)
Through many examples, we learned how to resolve the Get Gpu Name Tensorflow And Pytorch problem.
How do I find my GPU device name?
Find Out What GPU You Have in Windows In your PC's Start menu, type "Device Manager," and press Enter to launch the Control Panel's Device Manager. Click the drop-down arrow next to Display adapters, and it should list your GPU right there.
How do I check my GPU with PyTorch?
- torch.cuda.max_memory_cached(device=None) Returns the maximum GPU memory managed by the caching allocator in bytes for a given device.
- torch.cuda.memory_allocated(device=None) Returns the current GPU memory usage by tensors in bytes for a given device.
How do I check my GPU with TensorFlow?
You can use the below-mentioned code to tell if tensorflow is using gpu acceleration from inside python shell there is an easier way to achieve this.
- import tensorflow as tf.
- if tf.test.gpu_device_name():
- print('Default GPU Device:
- print("Please install GPU version of TF")
How do I get the GPU information in Python?
Find out if a GPU is available
- import GPUtil GPUtil. getAvailable()
- import torch use_cuda = torch. cuda. is_available()
- if use_cuda: print('__CUDNN VERSION:', torch. backends. cudnn.
- device = torch. device("cuda" if use_cuda else "cpu") print("Device: ",device)
- device = torch. device("cuda:2" if use_cuda else "cpu")
How do I physically identify my graphics card?
Windows® Device Manager
- Open Device Manager and expand Display adapters and the model of the graphic card should be visible.
- To determine the manufacturer of the graphic card, the Subsystem Vendor ID is required.
- Go to Details tab, select Hardware Ids under Property.
How do I know which GPU is being used?
Right click on the desktop and select [NVIDIA Control Panel]. Select [View] or [Desktop] (the option varies by driver version) in the tool bar then check [Display GPU Activity Icon in Notification Area]. In Windows taskbar, mouse over the "GPU Activity" icon to check the list.
What does CUDA () to PyTorch?
PyTorch's CUDA library enables you to keep track of which GPU you are using and causes any tensors you create to be automatically assigned to that device. After a tensor is allocated, you can perform operations with it and the results are also assigned to the same device.
Does PyTorch use GPU by default?
PyTorch defaults to the CPU, unless you use the . cuda() methods on your models and the torch. cuda.23-May-2018
How do you check if you have CUDA?
2.1. You can verify that you have a CUDA-capable GPU through the Display Adapters section in the Windows Device Manager. Here you will find the vendor name and model of your graphics card(s). If you have an NVIDIA card that is listed in http://developer.nvidia.com/cuda-gpus, that GPU is CUDA-capable.03-Aug-2022
What is GPU version of TensorFlow?
Note: TensorFlow binaries use AVX instructions which may not run on older CPUs. The following GPU-enabled devices are supported: NVIDIA® GPU card with CUDA® architectures 3.5, 5.0, 6.0, 7.0, 7.5, 8.0 and higher. See the list of CUDA®-enabled GPU cards.

@SGaist No, I cannot remove it.
That was not my question. In any cas take a look at setContentsMargins
@SGaist I implemented the following:
This had no effect on the appearance of the buttons within the verticalLayout. The buttons were still evenly spaced.
I am using Qt4.8 QtCreator 2.8.1 RedHat Enterprise 6.8
Could this be a bug in 4.8??
That's normal. If you want to have them all pushed up against each other on the top, you have to add a stretch after the last bottom with a value higher that the one used for the buttons. If you didn't set the stretch for the buttons (which is usually the case) then a stretch of one is enough. You can also use a QSpacerItem.
@SGaist I tried a stretch(1) shown commented out in my code below. I then implemented the spacerItem and put it into the layout via addItem()........
This seems to pile all the buttons on top of one another in the upper left corner of the mainWindow:
QPushButton *pushButton_1 = new QPushButton(this);
QPushButton *pushButton_2 = new QPushButton(this);
QPushButton *pushButton_3 = new QPushButton(this);
QPushButton *pushButton_4 = new QPushButton(this);
QPushButton *pushButton_5 = new QPushButton(this);
QPushButton *pushButton_6 = new QPushButton(this);
QSpacerItem *spc = new QSpacerItem(20,20,QSizePolicy::Expanding,QSizePolicy::Expanding);
pushButton_1->setText("One"); pushButton_2->setText("Two"); pushButton_3->setText("Three"); pushButton_4->setText("Four"); pushButton_5->setText("Five"); pushButton_6->setText("Six"); QVBoxLayout *pLayout = new QVBoxLayout(this); pLayout->addWidget(pushButton_1, 0, Qt::AlignTop); pLayout->addWidget(pushButton_2, 0, Qt::AlignTop); pLayout->addWidget(pushButton_3, 0, Qt::AlignTop); pLayout->addWidget(pushButton_4, 0, Qt::AlignTop); pLayout->addWidget(pushButton_5, 0, Qt::AlignTop); pLayout->addWidget(pushButton_6, 0, Qt::AlignTop); //pLayout->addStretch(1); pLayout->addItem(spc); setLayout(pLayout);
Can you show the result with your original code and the spacer item ?
By the way, are you locked to Qt 4 ? It has reached end of life a long time ago.
@SGaist For the foreseeable future, Yes I am stuck with 4.8. Later version has not been cleared through security protocols.
@SGaist I tried on my original post to include a .png of my gui but was unable to post it.
You can use an image sharing site like imgur.

HANA List all materials in 3rd level of a hierarchy
Concerning Graphical Calculation view in HANA 1.0, I have two questions around using HANA modeling tools:
How can I write a Graphical Calculation view that would give me all materials in a product hierarchy of CN1003 and display the text description of CN1003 as well?
I know I can use MARA.PRDHA to get the hierarchy for a material and T179T to get the text for a hierarchy; but it seems I need to generate a calculated column to just contain the first 6 characters then filter. but best practices indicate to not filter on a calculated column. So what's the right approach here? Is there a table I can join to which breaks the hierarchy down? so I can filter on the first two segments of 'CN' and '1003'?
For example:
MARA
+-------+--------------+
| MATNR | PRDHA |
+-------+--------------+
| 12345 | CN1003 |
| 12346 | CN10034231 |
| 12347 | CN1003423112 |
| 12348 | CN1002 |
| 12349 | FK1003 |
+-------+--------------+
T179T
+--------------+----------+
| PRODH | VTEXT |
+--------------+----------+
| CN1003 | Widgets |
| CN1002 | Magnets |
| CN10034231 | Tall |
| CN1003423112 | Red |
| FK1003 | Minerals |
+--------------+----------+
Expected Results:
+-------+---------+
| MATNR | VTEXT |
+-------+---------+
| 12345 | Widgets |
| 12346 | Tall |
| 12347 | Red |
+-------+---------+
in a Graphical calculation view: what is the purpose of setting a semantic type of a varchar(8) field to date? I thought this would cast the "date" varchar(8) field to a date datatype to be consumed by a Universe from the Calculation view; but apparently not. So Must I use a calculated column to convert this non-date date to an actual date datatype and isn't that against best pratices as again I'm filtering on a calculated column? So how do I get my string date to a date to do this? Or should I require my users enter a string date which seems like a bad UI choice in my reporting BI universe.
Why doesn't HANA just store dates as dates!?
These are two well written questions - thanks for that.
For the second question, the answer is fairly straight forward: the semantic property of fields in calculation views is really just an indicator for the front-end tool to "do the right thing" with it. It's mostly used by SAP front-end tools and AFAIK not really broadly used by any other tool.
As for the date data storage: that's a SAP ABAP idiosyncrasy design decision that has been in place for many decades. It allows SAP ABAP to store date/time information on any supported DBMS with the guarantee to get back the data in exactly the same way with a clearly defined semantic.
The ABAP data types are called DATS and TIMS and represent the date/time information in a character format.
If you want to enable filtering based on actual dates (or even on a hierarchy of date/time information), then the SAP tools (like SAC) support this out of the box. Alternatively, you can provide a value help view that performs the data type conversion ad-hoc for the selection and convert the filter condition back to the DATS/TIMS format.
That way, the conversion effort is minimal compared to the remaining query processing.
Concerning the first question, I'm not sure that I see the problem here.
Matching up the texts with the hierarchy identifiers can be done via a simple text-join (or a regular join).
Your filtering can easily work on a value help view (again) based on the text table that presents the de-composed (pun intended) string parts to the end-user.
Based on the selection, the join from the text-table to the parts-table will only include the selected records.
Again, the conversion effort is done only once on the smaller table (the table with the smaller dictionaries).
There is not hard and fast rule that states that you have to pre-compute every data transformation in SAP HANA. Quite the opposite is true. With the mentioned ad-hoc transformations in the value helper views, you can avoid needless conversion on large tables without additional pre-computed structures.
The other remark to this I can offer is that, in my experience, it really does not pay off to introduce pre-calculated columns and indexes before an actual performance issue had been identified.
It does, however, pay off to think about when, where and why data will be transformed and design accordingly.
Appreciate your time: and Pardon my ignorance here; but a value help view that decomposes the hierarchy must do so using calculated columns correct? So am I not violating best practice by filtering on that calculated column from the value help view? (Maybe I just don't understand what a value help view is though)
I keep re-reading this and gaining what I believe are better insights to your answer. So based on the comment; "the conversion effort is done only once on smaller table"; I think you're saying it's ok to filter on a calculated column in this case; because we're not doing it on the whole transaction table but instead the T179 master data/config only. That is then INNER joined to MARA for only those that are CN1003 and in this case the filter on a calculated column is the "Best practice"

Functions Slack tests failed when upgrading libraries-bom
#7355 upgraded the core set of client libraries across many java-docs-samples directories, and the build failed on the test below. This issue has been created to upgrade to the latest com.google.cloud:libraries-bom along with any other matching dependencies, and ensure that the test works.
My quick analysis here is:
The Knowledge Graph library depends on an older 1.3.1 version of google-api-client, and 2.0.0 is installed with this upgrade.
The Knowledge Graph library version in pom.xml is v1-rev20200809-1.32.1, but there have not been any new versions published since 2020.
So, if there is not a way to upgrade the dependencies to make this sample work, we should either remove the sample or the dependency on google-api-services-kgsearch.

Additional security features in Windows 8 include two new authentication methods tailored towards touchscreens (PINs and picture passwords) the addition of antivirus capabilities to Windows Defender (bringing it in parity with Microsoft’s Security Essentials software) SmartScreen filtering integrated into the desktop, and support for the “Secure Boot” functionality on UEFI systems to protect against malware infecting the boot process. Parental controls are offered through the integrated Family Safety software, which allows parents to monitor and control their children’s activities on a device with activity reports and safety controls. Windows 8 also provides integrated system recovery through the new “Refresh” and “Reset” functions.
Q4. Which browser microsoft gives with windows8?
Internet Explorer 10 with windows8 pack and other browsers of chrome and firefox can be downloaded .
Q5.What are the Minimum requirments for windows8?
Processor 1 GHz clock rate
Memory (RAM) IA-32 edition: 1 GB
x64 edition: 2 GB
Graphics Card DirectX 9 graphics device
WDDM 1.0 or higher driver
Display screen 1024×768 pixels
Input device Keyboard and mouse
Hard disk space IA-32 edition: 16 GB
x64 edition: 20 GB
Q6.Tell about the software compatibility in windows8.
The three desktop editions of Windows 8 are sold in two sub-editions: 32-bit and 64-bit. The 32-bit sub-edition runs on CPUs compatible with x86 architecture 3rd generation (known as IA-32) or newer, and can run 32-bit and 16-bit applications, although 16-bit support must be enabled first. (16-bit applications are developed for CPUs compatible with x86 2nd generation, first conceived in 1978. Microsoft started moving away from this architecture since Windows 95.
The 64-bit sub-edition runs on CPUs compatible with x86 8th generation (known as x86-64, or x64) or newer, and can run 32-bit and 64-bit programs. 32-bit programs and operating system are restricted to supporting only 4 gigabytes of memory while 64-bit systems can theoretically support 2048 gigabytes of memory.64-bit operating systems require a different set of device drivers than those of 32-bit operating systems.
Windows RT, the only edition of Windows 8 for systems with ARM processors, only supports applications included with the system (such as a special version of Office 2013), supplied through Windows Update, or Windows Store apps, to ensure that the system only runs applications that are optimized for the architecture. Windows RT does not support running IA-32 or x64 applications. Windows Store apps can either be cross-compatible between Windows 8 and Windows RT, or compiled to support a specific architecture.
Q7. Windows8 and the start button.
in windows8 there is no start button but the start screeen button and that displays the screen with the apps.
but we can get back our start button.
Q8.Is Adobe Flash supported on Internet Explorer 10?
Internet Explorer 10 includes Adobe Flash as a platform feature. Flash will be available, out of the box for Windows 8, on both Internet Explorer, and Internet Explorer for the desktop. Users can turn it on or off on the Manage Add-ons dialog box. Administrators can use the following Group Policy setting to control Flash usage in their environments: “Turn off Adobe Flash in Internet Explorer and prevent applications from using Internet Explorer technology to instantiate Flash objects”.

NVD3 Sunburst Zooming into Wrong Section
When creating a sunburst chart with NVD3 (version 1.8.1) and D3 (version 3.5.8), I find that when I click on some lowest-level slices, it zooms into the incorrect section of the graph:
nv.addGraph(function () {
chart = nv.models.sunburstChart();
chart.color(d3.scale.category10());
d3.select("#test1")
.datum(getData())
.call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
For instance, in this JSFiddle, when clicking on "Pug" it zooms to "Sparrow", but all other transitions seem to be working.
I have been unable to find the cause of this, as the x scale does seem to change domain to the correct values.
Additionally, the JSON data seems alright.
How would I correct for this?
Your fiddle seems to work for me. Clicking on "Pug" correctly zooms in on "Pug".
Your fiddle works well on FF but on chrome clicking on "Pug" zooms to "Sparrow". Seems like the nvd3 library has an issue... however if you reduce the data to what is required it wrks well https://jsfiddle.net/cyril123/nLt6nmv9/2/
As an addition to my first comment, for me Chrome 46, IE 11 and FF 41 are all doing fine. @Cyril
Hmm i am using chrome(Version 46.0.2490.80 (64-bit)) installed on ubuntu and i am able to recreate the issue :(
@Cyril I am running almost the same version Version 46.0.2490.86 m on a Win 8. However, the JSFiddle as it is linked to didn't work complaining about mixed content. I had to adjust either the JSFiddle from HTTPS to HTTP or the loading of D3 to HTTPS. As expected, both ways won't change the behaviour of the code.
@altocumulus sorry about the mixed content error. I was loading the d3 library from cdnjs but it was over HTTP. I have updated the JSFiddle to correct for this.
@Cyril I can confirm that it is not working with Google Chrome Version 46.0.2490.86 (64-bit) installed under Linux Mint. But it does work in Firefox 42.0 for Linux Mint.
Yea true the issue is more about Linux Google chrome @altocumulus yeah i did the https change.
@bradley Can you reduce the data set to relevant nodes as shown in my fiddle above in that case the error is gone. try that..
@Cyril Thanks for that, yes, I had noticed that if only those nodes are used in the data, then the problem goes away (a colleague also tried removing the larger nodes at random, sometimes the problem persisted and sometimes it remained). However, the data in the current form (including all the nodes called "node") is how we would need it, but we have simply obfuscated all the names.

The worksheets which make up the middle section of HIPR are probably the most important part of the reference. They provide detailed information and advice covering most of the image processing operations found in most image processing packages. Generally, each worksheet describes one operator. However, in addition, many worksheets also describe similar operators or common variants of the main operator. And since different implementations of the same operator often work in slightly different ways, we attempt to describe this sort of variation as well.
The worksheets assume a basic knowledge of a few image processing concepts. However, most terms that are not explained in the worksheets are cross-referenced (via hyperlinks where applicable) to explanations in the A to Z or elsewhere. This means that the worksheets are not swamped with too much beginner level material, but that at the same time such material is easily available to anyone who needs it.
Some of the worksheets also assume some mathematical knowledge, particularly in the descriptions of how the various operators work. However this is rarely important for understanding why you might use the operator.
The worksheets are divided into nine categories:
These categories are arranged in very approximate order of increasing difficulty (so that the easiest and often most useful categories come first). The categories are largely independent however, and may be tackled in any order.
Within each category, the individual worksheets are also arranged in approximate order of increasing difficulty and decreasing usefulness. The worksheet ordering is slightly more important than is the case with categories, since later worksheets tend to assume some understanding of earlier worksheets. However, as usual, any references to information contained in earlier worksheets will take the form of hyperlinks that can be quickly followed if necessary.
Each worksheet nominally consists of the same set of sections, although some of them are omitted on some worksheets. The sections are:
The main heading of each worksheet gives what we believe is the most appropriate name for the operator concerned. This is usually the commonest name for the operator, but is sometimes chosen to fit in with other operator names. The purpose of the Common Names section is to list alternative names for the same or very similar operators.
This section provides a short one or two paragraph layperson's description of what the operator does.
Unsurprisingly, this section explains how the operator concerned actually works. Typically, the section first describes the theory behind the operator, before moving onto details of how the operation is implemented.
This is one of the more important parts of the worksheets, and often the largest. This section provides advice on how to use an operator, illustrated with examples of what the operator can do, and examples of what can go wrong. An attempt is made to provide guidelines for deciding when it is appropriate to use a particular operator, and for choosing appropriate parameter settings for its use.
The Guidelines section contains imagelinks like this one:
which represent example images.
Image links appear as small pictures (known as thumbnails) which when clicked on cause the corresponding full-sized image to be displayed. Try it.
The Guidelines section often provides worked through examples of common image processing tasks that illustrate the operator being described.
This section is optional, and describes related operators that are not sufficiently different from the current operator to merit a worksheet of their own, but have not been adequately covered in the rest of the current worksheet.
Exercises are provided to test understanding of the topics discussed on the worksheet. A proportion of the questions involve practical exercises for which the use of an image processing package is required. Suggestions for suitable test images from the image library are also given.
This section lists bibliographic references in a number of popular image processing textbooks for the operator concerned.
This section is provided to allow the person in charge of installing HIPR to add information specific to the local installation. Suitable information would include details about which operators in local image processing packages correspond to the operator described. More details are given in the section on adding local information.
At the top of almost every page in the hypermedia version of HIPR appear up to four navigation buttons. On pages that occupy more than about a screenful, the buttons are duplicated at the bottom of the page. These navigation buttons help the user navigate around the worksheets quickly, and have the following functions:
Go to the top-level page.
Go left one page, when in a linear series of topics. Note that this is not the same as the Back button described elsewhere.
Go right one page, when in a linear series of topics. Note that this is not the same as the Forward button described elsewhere.
Go up one level
To understand the operation of the navigation buttons, refer to Figure 1 which shows part of the structure of HIPR.
Figure 1 The structure of part of the worksheet section of HIPR. The arrows show possible transitions between HIPR pages, and the arrow type indicates how this transition is achieved.
As the figure shows, the structure of HIPR is somewhat like the root system of a plant (or a tree turned upside-down), with each node branching out into finer detailed nodes. With this picture in mind it should be fairly easy to see how the various navigation buttons work.
Note that the left and right arrow buttons are not equivalent to the Back and Forward buttons provided by Netscape (at the top left of the screen). The Back button simply reverses the effect of the last link followed (no matter whether it was via a navigation button or via a hyperlink in the text of a worksheet). The Forward button can only be used after the Back button has been used, in which case it undoes the backwards jump.
It is possible, by following too many hyperlinks in succession, to become `lost in hyperspace', i.e. to become confused as to where you are in the HIPR structure. In this case it is quite a good idea to press the Back button repeatedly until you return to somewhere you recognize. Alternatively, just hit the Home HIPR navigation button to get back to the top level again.

Some thoughts about the services Linux.Pizza offers
And the possible future it has
The TL;RD of this post is: – Linux.Pizza will not actively deploy new services – Linux.Pizza are going to discontinue some services within 12 month (from this post have been made) – Linux.Pizza will focus on Mastodon, Mirroring distros and DNS.
You might wonder why, if so – please continue to read.
The short version is – I have realized that I am not able to deliver quality services anymore. And this is due to lack of time, funding and increased stress at my main job.
And the longer version: One year ago, I was “forced” to change job in order to make things work with my family – kids started school and wife returned to studies. I could'nt work 40 minutes from home anymore and needed something more closer to home.
So I switched, even if I hated the fact that I had to.
Anyway, the new job is great! And as the only Systems Administrator I am responsible for everything IT and I have alot of freedom when it comes to the software stack the company will use and so on. I recently deployed Nextcloud and Matrix which has been great!
Family takes more time
My kids are getting bigger, and I have decided to spend more time with them instead of in front of the PC. I have actually realized that I can't miss the time that I have with my family, so I have to prioritize while I can.
Work takes alot of time aswell
My new role and the new job that I got has brought a lot of “unwanted” responsibilities – I tend to take stuff way to personal when it comes to IT stuff where I work. If something goes wrong – I blame myself very much. And that needs to stop aswell.
Linux.Pizza is not going to dissappear
While Linux.Pizza is down-scaling – it will not dissappear! The social aspect of mastodon has been very good and important for me atleast – I see it as a “premium social network”. It costs some money every month but I think it is worth it actually since I have gotten to know many good people from different cultures, geographic locations, religions and political backgrounds and that has been very refreshing!
mirror.linux.pizza is also going to be a thing – it is a official mirror for many distros and shutting down that would be very irresponsible.
FreeDNS is also going to stay active aswell.
So in short – Linux.Pizza will offer some service, but only those that I want and I will not wake up in the middle of the night anymore to fix broken services as I have used to the past years.
“It it ain't fun – don't do it!” – Someone on Mastodon
I hope that you understand, and if you are in need of other services similar to those Linux.Pizza has offered – please check out The Librehosters Network.

Dr Laura Hay will be presenting a paper entitled “The Novelty Perspectives Framework: A new conceptualisation of novelty for cognitive design studies”. The paper forms part of our broader research programme as part of the ImagineD vision.
We’re delighted to announce that this year we’ll also be presenting our ongoing research in neuroscience and cognition at the ICED marketplace: an entirely new format for researchers to showcase their research at ICED. We’re excited to share our research using fMRI, EEG, and novel behavioural experiments. Come along to the marketplace on Wednesday, 7th August between 11:45 and 13:30 to find out more!
Highly commended award at Strathclyde Images of Research competition
We were delighted to receive a highly commended award from the judges at this year’s Images of Research competition for our entry “ImagineD: Realising your imagination”.
The ImagineD research project envisions a future for Computer Aided Design where designers can seamlessly realise their imagination in the digital world. To achieve this vision, we are combining multidisciplinary expertise to study cognitive, neural and gestural activity in creative design. This image shows our vision and the results from our neurological research, highlighting the regions of the brain associated with product design engineering ideation.
Poster abstract accepted for the annual meeting of the Cognitive Neuroscience Society
We are pleased to announce that our poster abstract, “The neural underpinnings of creative design” has been accepted for the 2019 annual meeting of the Cognitive Neuroscience Society
We will be travelling to San Francisco to present out work in March 2019. The conference takes place March 23-26 and involves “invited symposia, symposia, posters, awards, a keynote address, and most importantly the opportunity to connect with colleagues.”
The purpose of the meeting is to bring together researchers from around the world to share the latest studies in cognitive neuroscience.
For more information please check the conference website.
Journal article accepted in Brain and Behavior
We are pleased to announce that our paper, “Functional neuroimaging of visual creativity: a systematic review and meta-analysis,” has been published in the open access journal Brain and Behavior.
The paper synthesises functional neuroimaging studies of visual creativity. Seven functional magnetic resonance imaging (fMRI) and 19 electroencephalography (EEG) studies were reviewed, comprising 27 experiments and around 800 participants. A meta-analysis conducted on the fMRI studies suggests that the thalamus, left fusiform gyrus, and right middle and inferior frontal gyri may be involved in visual creative ideation, a key component of design ideation. Additionally, the EEG studies suggest that there may be a tendency for decreased alpha power during visual creativity compared to baseline, although findings are inconsistent.

2n2222a as a Switch
I just connected a very basic transistor as a switch circuit, and was trying to control it with a function generator with a schematic shown below.
I set the function generator output to 1HZ , 5V peak(0-5v) PWM with 50% Duty cycle.
However the circuit showed a weird behavior.
When the voltage supply was at 5V, I got an expected output across the Resistor with peak of 5V.
However the behavior started changing when I went above 5V.
At 5.9V, the output was something like:
The amplitude of that ringing increases with input voltage.
Any ideas on why this might be happening?
My Guess is that, it might be since the upper end of resistor becomes floating when transistor is OFF. If so, why does it show a clean output till 5V.
This looks like a simulation. I'd check out the exact simulation parameters of the function generator and V1 to make sure there isn't a problem with those. Keep in mind that when the base is higher voltage than the collector, it acts more like a diode than a transister.
This is an oscilloscope probe shot.
Isn't the typical 2n2222a/2n3904 npn transistor used as a switch when in common emitter (load on the collector)? Or are you intentionally putting the load on the emitter?
The output high voltage from the emitter of Q1 will never exceed Vb-Vbe. If the maximum base drive voltage is 5V, then the emitter will never be able to rise above approximately 4.3 volts when Q1 is saturated.
If the power supply increases to 5.9 Volts, then the transistor is operating in a linear region and the difference of 5.9-4.3 is dissipated across the CE junction. As soon as the emitter tries to rise up, it clamps off the base and shuts down a little until it reaches equilibrium. If the trace you show is of the actual circuit and not of a simulation, then the ringing is most likely cause by some noise source in the circuit as 1Hz is to slow for it to be a transient response.
The upper end of R1 never floats. It is bound by the Vbe junction of Q1.
If you wish to use a high side driver, then perhaps consider a PNP device. If you want a low side driver, then use an NPN device. this will free R1 from Vbe.
This is a commonly encountered gotcha in the analog world.
Emitter followers are prone to oscillation when there is a stiff (eg. bypassed) base source and some stray inductance kicking around, especially when they have a capacitive load (such as a scope probe). If you look at the arrangement, it's really a Colpitts oscillator!
Your oscillation looks to be relatively low frequency, but it's probably your digital scope lying to you (aliasing), as they are wont to do.
Try a series base resistor of 100 ~ 1000 ohms and I bet the oscillation disappears.

Chapter 1454 – Give Them a Taste of Their Own Medicine abashed scold
“It’s a ineffective struggle…”
Savignes allow out a smallish sigh of pain relief.
Or even for the fact that many of them ended up projections, all people can have rolled up their sleeves and commenced battling.
This issue instantly ignited the fuse. Everyone’s emotions had been for instance a early spring that was forced on the reduce these earlier day or two. With this particular, the many acc.you.mulated dissatisfaction with their hearts and minds erupted. They directly split into two categories. A single class was advocating war although the other was to opt for escaping. The debate was extremely extreme.
Several of the higher echelons with the societies who had been against triggering trouble couldn’t restrain themselves nowadays and begun whining loudly.
Han Xiao directly grabbed the banners.h.i.+p and sucked it into his entire body, acquiring Savignes and also the higher echelons of the s.h.i.+p.
The High History of the Holy Graal
He converted to consider the countless troops during the cabin and saw a feverish look on each of their faces. Conflict was their specialization.
Section 1454 Supply Them With a flavor of Their Own Remedies
Dream Tales and Prose Poems
“Isn’t the World Tree Society still struggling using the three Widespread Societies? Why have they get into us?”
During the conference room within the Star Alliance’s money.
“It’s simply a ineffective struggle…”
They believed that the 3 Widespread Societies were still preventing the whole world Plant into the loss, but simply because they experienced found out their location, that they had deployed a percentage of their own makes to address using them. This feeling was like people were enjoying the sufferings of other individuals, even so the sufferings suddenly appeared themselves mind.
They believed the 3 Worldwide Societies were still fighting the whole world Shrub to your passing away, but mainly because they experienced uncovered their place, they had used some of their own energies to fight with them. This feeling was like they were experiencing and enjoying the sufferings of many others, however the sufferings suddenly made an appearance themselves head.
Having said that, right before he could complete speaking, lots of the s.p.a.ces.h.i.+p operators were actually already excessive sweating a lot.
Just after, he suddenly lifted his palm and punched. Vigor burst open out like a gamma-ray burst open, distributing in the sizeable place and instantly vaporizing a sizable group of battles.h.i.+playstation that have been getting ready to counterattack.
The Legend Alliance was developed via the alliance in excess of forty cultures. These were not united from the start and every acquired their very own standpoints for positive aspects. Normally, they could be collected collectively, but when faced with the pressure of the highly effective unfamiliar attack, inner clashes promptly erupted.
“For the mom tree! For Dad G.o.d!”
“It’s basically a ineffective struggle…”
steve young hall of fame
Following the quarrel, the management of a few societies gave out orders placed without the doubt. They did not pay attention to the Celebrity Alliance’s sales at all and filled up their information and human population. They started to get away from hurriedly, preparing to get away coming from the Legend Alliance’s territory and enter in the unexplored universe.
Or even for the reality that the majority of them ended up projections, every person may have rolled up their sleeves and started out preventing.
In the beginning, however most civilizations were actually angry and panicked, that they had not wanted to give up on their houses. However, when they spotted somebody working aside decisively, they without delay grew to become troubled. Considering that the other individuals acquired already run away, whenever they did not continue, would not they be living behind to help you other people cover their retreat? How could this do!
The slot about the mum world from the Lore Civilization was already packed with folks. Zero-gravitational forces move vehicles stuffed the materials on the fleet individually. A great number of frightened people lined up to board the s.h.i.+ps in the orders placed of armed troops. Regardless of how anxious these were, they can only reduce their feelings and pay attention to the orders placed obediently.
The Superstar Alliance was created because of the alliance in excess of forty civilizations. People were not united initially and each had their own individual standpoints for added benefits. Usually, they might be gathered together with each other, but when confronted with the strain of a effective international intrusion, internal situations without delay erupted.
the mountebank scene in volpone
In the principal personalities.h.i.+p with the Legend Alliance’s rapid assistance troops, the middle-old commander by using a solid character gripped the advantage of the dining room table tightly with both hands. He gritted his the teeth and looked over the opponent troops away from window, a great number of days much more a lot of than his own. His cardiovascular system is at agony as he permit out a hoa.r.s.e roar:
“What deal with! Also the three Widespread Societies have been no match for the World Plant, they had been crippled in a few years. We can’t defend our own territories whatsoever. We should rapidly migrate the refugees, sustain our tinders, and give up on our territories!” “How can we achieve that? A minimum of we still need the strength to fight! The Entire World Shrub is wreaking destruction in my territory. On condition that absolutely everyone delivers out reinforcements, we will definitely have the ability to beat the earth Plant!” someone else claimed in a very very low tone of voice. “Bullsh*t! We don’t even have enough troops, just how do we assist you to?!” A different person shouted.
The Legend Alliance Leader frowned and checked tired. His eye were actually bloodshot with his fantastic tone of voice was extremely hoa.r.s.e. Savignes trembled slightly and explained by using a shaking sound, “Could it be which the Planet Plant Civilization believes they have already crippled the three societies and wants to battle on two fronts? What should we do?”
He changed to see the countless troopers within the cabin and discovered a feverish look on all of their facial looks. Conflict was their specialized.
On the primary personalities.h.i.+p on the Star Alliance’s quick assist troops, the center-aged commander that has a powerful personality gripped the advantage of your kitchen table tightly with both of your hands. He gritted his pearly whites and looked over the adversary troops beyond the windowpane, many periods more a lot of than his own. His cardiovascular system was in discomfort because he allow out a hoa.r.s.e roar:
“His Excellency Savignes has become seized by the opponent!”
In the flags.h.i.+p around the globe Plant fleet, the center Tree California king appeared downward in the world that has a glimmer as part of his vision. Vast clairvoyant strength acquired already included the total environment, hypnotizing all existing creatures to stop on escaping and voluntarily go into the beginnings to become a new member of the planet Tree.
