Why can two (or more) electric [field lines](http://en.wikipedia.org/wiki/Field_line) never cross? | 2014/04/06 | [

] | Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location. This could never be the case. Every single location in space has its own electric field strength and direction associated with it. Consequently, the lines representing the field **cannot** cross each other at any given location in space.
For example, in the image below, the lines are intersecting and hence there are **two directions** for Electric Field.
 | The electric field at any point is the sum of all the fields due to each individual charge in the system. The field has a magnitude and a direction. The field lines are a representation of the magnitude and direction of the field over an illustrated area. The field lines point in the direction of the field. If lines from two sources were to cross, we could effectively sum the two fields at that point and redraw the field lines with the new direction. Thus, we can say field lines never cross because the sum of two vectors can only have one direction (with the exception of the zero vector) |

51,590 | About 2-3 months ago I decided to start my own batch of vinegar. I started with some Braggs apple cider vinegar which contains the mother, and I added some old wine and some fruit juice to the mix. I kept it in a dark and warm place, as per instructions online. A few layers of cheesecloth were placed on top to allow it to air, without letting anything else get into it.
When I recently opened it, I found a layer of what appears to be a yellow-orange mold on top. There are also some small worms or maggots living on the top, but that doesn't seem as problematic to me.
As you can (sort of) see in this picture above, there is definitely a mother at the bottom. The mother has grown since I last saw it. I am not sure what to think about that top layer though. Is the vinegar batch completely spoiled?

First off, the mold. This is nothing to worry about, you should be skimming it off but as far as Vinegar creation it's normal and to be expected.
These "worms" have a name :-) Turbatrix Aceti (a.k.a Vinegar Worm) you can read more about them here -> [wiki/Turbatrix\_aceti](http://en.wikipedia.org/wiki/Turbatrix_aceti)
Why is that mold there? Well if you think about the fermentation process. It's just thousands of bacteria 'eating' your 'mother' now they have to produce something as a byproduct which is the mold you see on the top. Get rid of it and leave it to carry on.

Mold = Bad (Clean it off)
Froth = Good (Leave it alone til' it turns to mold.
**Question:** Is the vinegar batch completely spoiled?
**Answer:** No. | I have salvaged both vinegar and kombucha from mild mold by removing what I could, increasing stirring to twice daily and watching it more carefully and removing the very first signs of opaque, white , blue green or furry. I also spray the top with straight vinegar. Once the mixture gets acidic enough the mold won't grow. If it's kombucha you need more starter from your last batch to get the ph down enuf to prevent mold. |

**Question:** Is the vinegar batch completely spoiled?
**Answer:** No. | I have made several batches of vinegar and have also noticed mold - usually light colored - most dramatically on the raspberry vinegar that I made. If i just leave the mold alone it appears to be consumed or disappears after a little bit. It may just have been the scum that precedes the mother but it always disappears. |

* Windows Vista 32-bit Edition
* Mobility Radeon

However, if I change to just "Radeon" for the last selection there, I can find a "Radeon HD 3600 Series" model in the list.

OK, I'll explain further. ATi typically does not release updated laptop drivers. The monthly updates are for desktops. So, you have to get your laptop video drivers from your laptop vendor, which updates them less than occasionally.
So, the folks at driver heaven take ATi's latest releases and hack them for laptop users. | In your case you would use the 3000 series drivers. For the record, when they say '3000 series', that means it pretty much covers all the models from 3000 to 3999. Not that they have a 3999 model but you get the point. It's basically like saying 3xxx series.
When you run the install the software might say that your model is not found, but you can select the HAVE DISK option and manually pick from the list using the INF in your ATI driver folder.
Some would say this is not recommended but in my experience, I haven't had any issues yet.

] | In your case you would use the 3000 series drivers. For the record, when they say '3000 series', that means it pretty much covers all the models from 3000 to 3999. Not that they have a 3999 model but you get the point. It's basically like saying 3xxx series.
When you run the install the software might say that your model is not found, but you can select the HAVE DISK option and manually pick from the list using the INF in your ATI driver folder.

21,084 | For some environments taking an action may not update the environment state. For example, a trading RL agent may take an action to buy shares s. The state at time t which is the time of investing is represented as the interval of 5 previous prices of s. At t+1 the share price has changed but it may not be as a result of the action taken. Does this affect RL learning, if so how ? Is it required that state is updated as a result of taking actions for agent learning to occur ?
In gaming environments it is clear how actions affect the environment. Can some rules of RL breakdown if no "noticeable" environment change takes place as a result of actions ?
Update:
"actions influence the state transitions", is my understanding correct:
If transitioning to a new state is governed by epsilon greedy and epsilon is set to .1 then with .1 probability the agent will choose an action from the q table which has max reward reward for the given state. Otherwise the agent randomly chooses and performs an action then updates the q table with discounted reward received from the environment for the given action.
I've not explicitly modeled an MDP and just defined the environment and let the agent determine best actions over multiple episodes of choosing either a random action or the best action for the given state, the selection is governed by epsilon greedy.
But perhaps I've not understood something fundamental in RL. I'm ignoring MDP in large part as I'm not modeling the environment explicitly. I don't set the probabilities of moving from each state to other states. | 2020/05/11 | [

] | A very vague question. What's the objective?
Reinforcement Learning (RL) typically uses the Markov Decision Process framework, which is a sequential decision making framework. In this framework, actions influence the state transitions. In other words, RL deals with controlling (via actions) a Markov chain. The objective in RL is figure out how to take actions in an optimal (in some sense) way!
If, in the application you mentioned, the actions don't influence the state transitions and the objective is to predict states, RL is not required. It's just a regression/ time-series problem. | It seems to me that you are confusing two things, **State of the agent** and **State of the environment**.
Think about a robot learning to walk on a rugged terrain.
The actions of the robots don't change the terrain at all ! The robot can include in his own state, part of the environment state, the topology of the terrain in front of him for instance.
In an MDP, an agent may or may not modify the environment state, in your case, if we make the assumption that you don't manipulate the market, you can consider that you don't modify the environment state.
Your issue might be in the way you designed your agent, relying only on a part of the state environment, and not really having any state of his own, such as a portfolio for instance.
If you're only interested in the way the state environment changes, then the above answer is right, the RL framework may not be a good fit.
Finally, you don't have to model explicitly the environment, that's the beauty of model free RL ! Q-learning, that you mentioned, is model-free. |

178,682 | I use a MacBook Pro as my primary machine, but my work targets Linux servers. I'm currently on a project with multiple dependencies, and which is configured for Ubuntu.
1. Configuring all these dependencies on OSX is a pain. I've been through [Macports](http://www.macports.org/), [Fink](http://www.finkproject.org/) and [Homebrew](http://github.com/mxcl/homebrew). They are all nice, but they don't provide a 100% drop-in replacement for Ubuntu packaging. Rewriting all the deployment scripts just to accommodate one Mac developer seems like a waste of time.
2. Dual-booting Ubuntu on this Mac doesn't seem like an option yet. The current hardware generation (7,1) is not fully supported.
3. Using an Ubuntu VM for all my development work seems to be the way to go. I'm using VirtualBox at the moment. Seamless mode is nice, but I wonder if VMware Fusion or Parallels will be nicer.
So here is the question: what's the best VM app for Linux desktop guests on a Mac OS X host? [VirtualBox](http://www.virtualbox.org/), [VMware Fusion](http://www.vmware.com/products/fusion/), [Parallels](http://www.parallels.com/products/desktop/), or any other? What do you like about it?

] | In the SHA-1 example you give, there is only a single input to the function, and any correct SHA-1 implementation should produce the same output as any other when provided the same input data.
For AES however things are a bit tricker, and since you don't specify what you mean exactly by "AES", this itself seems likely to be the source of the *perceived* differences between implementations.
Firstly, "AES" isn't a single algorithm, but a family of algorithms that take different **key sizes** (128, 192 or 256 bits). AES is also a block cipher, it takes a single block of 128 bits/16 bytes of **plaintext** input, and encrypts this using the key to produce a single 16 byte block of output.
Of course in practice we often want to encrypt more than 16 bytes of data at once, so we must find a way to repeatedly apply the AES algorithm in order to encrypt all the data. Naively we could split it into 16 byte chunks and encrypt each one in turn, but this mode (described as Electronic Codebook or ECB) turns out to be [horribly insecure](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_Codebook_.28ECB.29). Instead, various other more secure **[modes](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation)** are usually used, and most of these require an **Initialization Vector (IV)** which helps to ensure that encrypting the same data with the same key doesn't result in the same ciphertext (which would otherwise leak information).
Most of these modes still operate on fixed-sized blocks of data, but again we often want to encrypt data that isn't a multiple of the block size, so we have to use some form of **[padding](https://en.wikipedia.org/wiki/Padding_(cryptography))**, and again there are various different possibilities for how we pad a message to a length that is a multiple of the block size.
So to put all of this together, two different implementations of "AES" should produce the same output if *all* of the following are identical:
* Plaintext input data
* Key (and hence key size)
* IV
* Mode (including any mode-specific inputs)
* Padding | Iridium covered many of the causes for a different output between TrueCrypt and other programs using nominally the same (AES) algorithm. If you are just checking actual initialization vectors, these tend to be done using ECB. It is the only good time to use ECB -- to make sure the algorithm itself is implemented correctly. This is because ECB, while insecure, does work without an IV and therefore makes it easier to check "apples to apples" though other stumbling blocks remain as Iridium pointed out.
With a test vector, the key is specified along with the plain text. And test vectors are specified as exact multiples of the block size. Or more specifically, they tend to be exactly 1 block in size for the plain text. This is done to remove padding and mode from the list of possible differences. So if you use standard test vectors between two AES encryption programs, you eliminate the issue with the plain text data differences, key differences, IV, mode, and padding.
But note you can still have differences. AES is just as deterministic as hashing, so you can get the same result every time with AES just as you can with hashing. It's just that there are more variables to control to get the same output result. One item Iridium did not mention but which can be an issue is endianness of the input (key and plain text). I ran into exactly this when checking a reference implementation of Serpent against TrueCrypt. They gave the same output to the text vectors *only* if I reversed the key and plain text between them.
To elaborate on that, if you have plain text that is all 16 bytes as 0s, and your key is 31 bytes of 0s and one byte of '33' (in the 256 bit version), if the '33' byte was on the left end of the byte string for the reference implementation, you had to feed TrueCrypt 31 '00' bytes and then the '33' byte on the right-hand side to get the same output. So as I mentioned, an endianness issue.
As for TrueCrypt maybe not being secure even if AES still is, that is absolutely true. I don't know the specifics on TrueCrypt's alleged weaknesses, but let me present a couple ways a program can have AES down right and still be insecure.
One way would be if, after the user keys in their password, the program stores it for the session in an insecure manner. If it is not encrypted in memory or if it encrypts your key using its own internal key but fails to protect that key well enough, you can have Windows write it out on the hard drive plain for all to read if it swaps memory to the hard drive. Or as such swaps are less common than they used to be, unless the TrueCrypt authors protect your key during a session, it is also possible for a malicious program to come and "debug" the key right out of the TrueCrypt software. All without AES being broken at all.
Another way it could be broken (theoretically) would be in a way that makes timing attacks possible. As a simple example, imagine a very basic crypto that takes your 32 bit key and splits it into 2 each chunks of 16 bytes. It then looks at the first chunk by byte. It bit-rotates the plain text right a number of bits corresponding to the value of byte 0 of your key. Then it XORs the plain text with the right-hand 16 bytes of your key. Then it bit-rotates again per byte 1 of your key. And so on, 16 shifts and 16 XORs. Well, if a "bad guy" were able to monitor your CPU's power consumption, they could use side channel attacks to time the CPU and / or measure its power consumption on a per-bit-of-the-key basis. The fact is it would take longer (usually, depending on the code that handles the bit-rotate) to bit-rotate 120 bits than it takes to bit-rotate 121 bits. That difference is tiny, but it is there and it has been proven to leak key information. The XOR steps would probably not leak key info, but half of your key would be known to an attacker with ease based on the above attack, even on an implementation of an unbroken algorithm, if the implementation itself is not done right -- a very difficult thing to do.
So I do not know if TrueCrypt is broken in one of these ways or in some other way altogether. But crypto is a lot harder than it looks. If the people on the inside say it is broken, it is very easy for me to believe them. |

] | **Possibility #1**
If the folder is deleted or moved explorer windows will close themselves. Are these folders being manipulated in anyway?
**Possibility #2**
The other possibility is explorer having too many files open at once. A good fix for this is to enable "Launch folder Windows in a separate Process". It's a little know feature of windows that allows the machine to separate file/folder access from the Explorer GUI process (been around since XP).
It can be found under Control Panel > File Explorer Options > "View" Tab > Launch folder Windows in a separate Process
**Possibility #3**
Alternatively, you can check to make sure that explorer hasn't become corrupted.
1. Launch an administrator commandline (Win + X) -> Press "A"
2. Click yes to accept the UAC prompt
3. Type this command "sfc /scannow" (without the quotes)
Windows will scan all of its core files and fix any problem it finds. I am an IT professional and explorer generally starts to behave after theses steps have been exhausted. | The simple fix is to set the Drive Map GPO to use the Action UPDATE.
To stop your mapped drives disappearing or automatically closing:
Launch Group Policy Managementnetwork-mapped-drives-closing-spontaneously-automatically
Find your drive mapping GPO, right click on it and select EDIT
Expand USER CONFIGURATION > PREFERENCES > WINDOWS SETTINGS > DRIVE MAPS
Double click on the drive map that is automatically closing
Change the ACTION drop down from REPLACE to UPDATE |

I opened three Explorer Windows, one with the local C: drive, one with the profile mapped homeshare and one with the commonly used data storage share drive.

] | Updating a navigation database used to be considered *preventative maintenance* and was required to be performed by a mechanic under Part 135. However, the regulations were changed at the end of 2012 (here is the [final rule](https://www.federalregister.gov/articles/2012/11/29/2012-28845/pilot-loading-of-aeronautical-database-updates#h-36)) and it no longer falls under this category so pilots are allowed to update "aeronautical databases" (a new term) if it is "easy" to do (see the regulation quoted below for the exact requirements). There is no training requirement specified by the regulations, however there may be company specific procedures which require it.
[14 CFR 43.3](http://www.ecfr.gov/cgi-bin/text-idx?rgn=div5&view=text&node=14:1.0.1.3.21&idno=14#14:1.0.1.3.21.0.363.3) was updated, and now says (in part):
>
> (k) Updates of databases in installed avionics meeting the conditions

> by pilots provided:

>
> (1) The database upload is:
>

> (i) Initiated from the flight deck;
>
>
> (ii) Performed without disassembling the avionics unit; and
>
>
> (iii) Performed without the use of tools and/or special equipment.

>
> (2) The pilot must comply with the certificate holder's procedures or

>
> (3) **The holder of operating certificates must make available written

> (i) Perform the database update; and

> (ii) Determine the status of the data upload.
>
>
> | I assume that by updating you mean loading a pre-compiled database into the FMS, replacing the old one.
The RNAV database inside the FMS should be updated according to the 28 day Aeronautical Information Regulation and Control (AIRAC) cycle. Typically this is a maintenance task and the pilot has no play in this. Of course if the pilot also holds the required maintenance certificates, then he can update the database in the appropriate way. However, he is not acting in his capacity of pilot in that case, but wearing his maintenance hat.
In some cases the database update is not considered maintenance and can be performed by the pilot. 14 CFR Part 43 covers Maintenance, preventive maintenance, rebuilding and alteration. It contains an interesting section regarding databases; 14 CFR § 43.3(k) specifically addresses database updates.

> (k) ***Updates of databases in installed avionics meeting the conditions

If these conditions are not met, then there is a final escape door which might apply to Part 135 rotorcraft pilots:
[14 CFR § 43.3(h)](http://www.ecfr.gov/cgi-bin/text-idx?SID=9d7de8e7c84faf84a2822512f76c1002&node=14:1.0.1.3.21.0.363.3&rgn=div8) states:
>
> (h) Notwithstanding the provisions of paragraph (g) of this section,
> the Administrator may approve a certificate holder under Part 135 of
> this chapter, ***operating rotorcraft in a remote area***, to allow a pilot
> to perform specific preventive maintenance items provided—
>
>
> (1) The items of preventive maintenance are a result of a known or

>
> (2) The pilot has satisfactorily completed an approved training

> (3) There is no certificated mechanic available to perform preventive

---
**Summary**
When the database update meets the conditions stated in paragraph (k) of 14 CFR § 43.3 it is not considered maintenance and may be performed by the pilot.
When CFR § 43.3 (k) conditions are not met the pilot cannot perform the update unless the Administrator approves it under 14 CFR § 43.3(h). |

Here's [the link to the site](http://academic.depauw.edu/aevans_web/HONR101-02/WebPages/Fall%202007/Craig/Contact%20Website/Pages/movie.html) with the best analysis I noted.
To sum up, the primary differences are:
1. The number of characters in the transport to Vega; in the movie, there's only room for one. In the book, it seats five.
2. The character of Palmer Joss is a religious writer in the movie; in the book he's a preacher.
3. The end of the Cold War caused one of the novel's subplots to be dropped from the film.
4. There are (arguably) different motivations for some of the characters in the novel than as shown in the film.
5. The film apparently plays the "science-vs-religion" aspect up more than the novel.
6. The character of Ellie didn't face the sexism she encountered in the film.
7. The romantic aspect of the film does not exist in the novel.
[Here's another link](https://www.quora.com/How-similar-is-the-movie-Contact-to-Carl-Sagans-book-of-the-same-name) to a Quora question with some of the same points listed. | 5 people went in the book, and the conversations with the aliens were just amazing compared to movie. The conversation Ellie had with the alien alone makes the book a great read.
The endings were vastly different.
Movie: See, scientist lady! Faith CAN be good!
Book: Everything we know about the universe is wrong and the game
has seriously changed. *brain explodes*
*SPOILERS*

> The movie ending had a religious bent like if millions of people can believe Ellie on faith, maybe Ellie can believe in God. Also the conspiracy aspect about the length of the static, which was suppressed.

> The book ending touches the concept of reality itself, finding ordered data deep inside pi, leaving it hanging what that data may be... space bible? Encyclopedia Galactica? The Hitchhikers Guide to the Galaxy? More instructions?! I personally like to think that the data wiggles and is a nature-of-reality based universe internet.

] | Any camera is going to struggle with the dynamic range of that sort of situation. Very hard to get the room and the outside both exposed reasonably at the same time. With enough flash power you can do it by flooding the room with light I suppose.
But the easier way is to use a tripod and take two exposures, one for the inside and one for out, and blend them together in your editing tool. I think it's best if you leave the outside exposure pretty bright, otherwise it looks fake.
You can use HDR, but if you have a few windows that are easy to mask, I'd just blend two exposures manually.
Simple example:
Light exposure for the room
Dark exposure for the outside
Blended exposure
 | You've basically got three choices in such a situation:
* Use artificial light to bring the interior brightness up enough that the entire scene is within your camera's dynamic range. Anything from on-camera flash to multiple strobes.
* Take multiple images and combine them using one of several methods for compressing dynamic range. This could range from HDR with or without heavy tone mapping, to Exposure Fusion, to combining elements of multiple exposures by hand in Photoshop.
* Use a combination of both.
There has been some debate about which approach yields the best results. Which you choose will depend on what you want your final image to look like.

 | 1. HDR
2. Flash fill such that flash deals with inside view and ambient deals with exterior.
Juggle to suit. See photo example below.
3. Long exposure with a manually moved mask between light and dark to balance exposures. There is a whole art-form based around doing this.
4. Multiple exposures and manual combining. Can be reasonably easy with tripod due to sharply defined exterior / interior spaces in many cases.
5. Stan Rogers old time solution - stick ND material over windows on outside !!!!!!!!! [Wow!].
6. Handy pocket Mr Fusion halogen lamp. Hard to come by. So far.
One or more 100 Watt CFL tube (about 400 W - 500 W tungsten equivalent output) makes a fair not too dear reasonably compact stand in. (They sold these here (in NZ) for some years but have stopped doing so.
7. Long exposure with multiple manual flash washing. Takes some experience but you can differentially illuminate target area. I have never done this "in anger" with a flash but using an LED or other lamp to "wash" an area at night with long exposure can be great fun and even useful.

Photo: With and without fill flash. I had minimal time to 'play', so no effort made to optimise, and it uses on-camera flash. Given time I'd reduce flash level somewhat and better balance ambient and flash so some shadowing remains from eg phone on bed or grand old lady [tm].

 | Set camera to it's MANUAL MODE and walk over and set the exposure (shutter, aperture, and ISO) to the scene outside the window (just what you see out the window and no interior).
Set your flash to AUTO or FILL. Move to a position where the flash will not reflect (from a window, mirror, hanging photo, or any other reflective surface) directly back at the camera. Take the shot.
Evaluate the photo on your camera's LCD screen. If the interior is a little darker than you want, increase the flash output.

 | You've basically got three choices in such a situation:
* Use artificial light to bring the interior brightness up enough that the entire scene is within your camera's dynamic range. Anything from on-camera flash to multiple strobes.
* Take multiple images and combine them using one of several methods for compressing dynamic range. This could range from HDR with or without heavy tone mapping, to Exposure Fusion, to combining elements of multiple exposures by hand in Photoshop.
* Use a combination of both.
There has been some debate about which approach yields the best results. Which you choose will depend on what you want your final image to look like.

Humanity at this stage is a techno-organic species, one of the apex in the galaxy's history. Now the firm ive made so far has to do with humanity in some way.
The body: its humanoid in proportions due to it being a union of humanity.

The bones are composed of a calcium silicate crystal that is shinny and white. Then it is covered in an obsidian bone plates that hide certain parts of the thing.
At its center lies a red ruby core that pulses energy throughout the body.
It has a large number of angelic wings composed of red solar plasma with blue tips on them. Very much like Magnus the Red's wings just made of solar flames.
It has three burning eyes.
It also has throught the body circuit like patterns due to humanity's techno organic nature.
The colors. Red is a psychologically active color on humanity as such its the most abundant on us, likewise blue is our general fabourite as it is present in the tips of the wings.
The firey and luminat nature of its wings come from the favt that humans are creatures of the light and being in absence of it for long perooss of time fucks with our minds. The wings symbolize humanity's long wish for flight.
Its name when translated means the Crimson Daemon Star of a Thousand Wings.

OK, so it looks - well, it's pretty impressive, but it's not eldritch - "weird; sinister or ghostly".
For eldritch, you're better off sticking with the traditional: icky, maybe snakelike or octopoid or insectile. And whatever you do, get rid of the bright colors. No self-respecting eldritch creature is pretty.
Look - if you want eldritch, you want to scare the carp out of people, and not (primarily) by looking powerful. Think *sinister*. Think vicious. Think alien and uncaring.

] | Don't use console input with a GUI based applications. User input should be gained by using one or more of the available UI controls.
Painting in Swing can occur for any number of reasons, many of which you don't control, this means that when ever Swing wants to update your UI, it will call paint, meaning you are constantly being asked to provide a new word
Also, you are blocking the paint process, this means until you paint method exits, it's unlikely that anything will be painted
Start by taking a look at [How to create a GUI with Swing](http://docs.oracle.com/javase/tutorial/uiswing/) and, when you understand that, [Performing Custom Painting](http://docs.oracle.com/javase/tutorial/uiswing/painting/) | Because you put everything inside the paint function, it will be called again if the applet repaints. So you will notice if you don't resize the applet or do anything else that would cause it to repaint, then it will not have that double output. You can fix this by creating the applet from a main that contains the hangman text logic.
As for how to tell how many steps it took, you should have an extra counter initialized to 0 outside of the nested for loops and inside the inner nested for loop you should increment it. Since you break when the correct word is found, that counter will have the number of attempts. |

IRF520PBF at a common US distributor is 96 cents. | I've done a project similar to this, I made a network-controlled power board. I used a couple of **relays** to switch circuits on/off.
If you do go with relays, be sure to have a power diode placed in reverse so that when you close the relay the electromagnetic bubble doesn't fry your Arduino.
If the Arduino doesn't have enough current to switch the relay on, use a saturated NPN to boost the signal.
[This site](http://www.kpsec.freeuk.com/trancirc.htm#relays) has some good information on what I think your wanting.

I've found that the best (i.e. most painless) way is...
1. Use Glassfish - this is a well supported container for OpenSSO - use the developer profile to make your life even easier - use the quick setup steps as documented on the download page
2. Deploy OpenSSO as per the basic instructions (unpack the zip - deploy the war file to the default domain)
I've used the following as my setup steps (I use OpenSSO build 7):
* Under "Custom Configuration", click "Create New Configuration".
* Type the password "adminadmin" in the Password and Confirm fields. Click Next.
* In Server Settings, leave the defaults alone (or edit if if needed) and choose Next.
* In Configuration Data Store, leave the defaults alone (or edit if needed) and choose Next.
* In User Data Store, choose "OpenSSO User Data Store". Click Next.
* In Site Configuration, choose No (this installation will not use a load balancer). Click Next.
* In Default Agent User, enter admin123 as the password and confirmed password. Click Next.
* Click "Create Configuration".
* Click "Proceed to Login".
* Log in as "amadmin" with the password "adminadmin".
The instructions above are based on <http://developers.sun.com/identity/reference/techart/opensso-glassfish.html>
You've now got your basics up and running. Create a subrealm under / called users, and create an account or two in there.
Now prep your SP metadata. Don't put too much in your metadata to start with - keep it simple.
In the default page of the GUI, choose to create a hosted IDP. This is a pretty basic workflow. You should specify your /users realm and choose to use the test key alias for signing. The circle of trust you create can be called petty much anything.
When you complete the workflow you'll be asked if you want to import metadata for an SP - say yes and choose to import from your prepared metadata file.
At this stage you should be pretty much set up.
You'll want to grab your IDP metadata next. There are a few ways to do this. You could use "<http://servername:8080/opensso/ssoadm.jsp?cmd=export-entity>" or "<http://servername:8080/opensso/saml2/jsp/exportmetadata.jsp?realm=/users>".
... and that's pretty much it for setup.
If you run into issues interoperating with OpenSSO you can look in the OpenSSO data directory (~/opensso by default). There's debugging and logging information in the subdirectories under there. You can cross reference that information with the OpenSSO Wiki, which has some pretty good troubleshooting information. | Take a look at [this answer](https://stackoverflow.com/questions/6063158/public-saml-v2-service-providers-for-testing/42733310#42733310).

You'll want to grab your IDP metadata next. There are a few ways to do this. You could use "<http://servername:8080/opensso/ssoadm.jsp?cmd=export-entity>" or "<http://servername:8080/opensso/saml2/jsp/exportmetadata.jsp?realm=/users>".
... and that's pretty much it for setup.
If you run into issues interoperating with OpenSSO you can look in the OpenSSO data directory (~/opensso by default). There's debugging and logging information in the subdirectories under there. You can cross reference that information with the OpenSSO Wiki, which has some pretty good troubleshooting information. | Use [samlidp.io](https://samlidp.io), it is perfect and free for testing, you can setup your own IdP with a few clicks with adding your custom SP's metadata and that's all, it works. |
1,125,915 | I'm implementing a SAML 2.0 Service Provider and need to install a SAML 2.0 Identity Provider for testing. Given this need, the Identity Provider should ideally be free (or have a trial period) and be easy to set up and configure.
I'm looking for basic single sign on and single log out functionality.
I've tried Sun Opensso Enterprise. The price is right, but so far it's been a nightmare to configure. Also, its error messaging and logging leaves a lot to be desired and I'm often troubleshooting an issue that basically boils down to a misconfiguration or a counterintuitive default setting. | 2009/07/14 | [

It is packaged for most Linux distributions, so easy to install and to set up. | I have been struggling with testing SAML2 integration for a long time, and used OpenSSO. Since I discovered **OKTA** for testing applications <http://okta.com/> I haven't looked back. It is perfect, easy to use, and you can also create different users and send custom attributes back to the SP.
**OpenSSO** is not nice. For start you have those ridiculous captchas which don't even make sense. SSOCircle does not allow you to send custom attributes, it does not allow you to use SHA-256 encryption either, for what I've seen. OpenSSO does not give you any help about error messages unless you pay for their **debug** functionality (which is probably poor given the rest of the application works poorly). |

In my experience KVO tends to 'just work', which is nice. | When you use @property tags to [create getters/ setters](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/KeyValueCoding/Articles/AccessorConventions.html#//apple_ref/doc/uid/20002174-BAJEAIEE) the magic is auto wired for To-One relationships and you only need to addObserver... and implement the observe... method to catch the updates.

The [documentation here](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/KeyValueCoding/Articles/AccessorConventions.html#//apple_ref/doc/uid/20002174-178830-BAJEDEFB) is key and the understanding that there are two sections... Indexed collections and Unordered collections. It really helped me to understand that if my @property is an NSMutableArray you need to look at the methods in the Indexed area and if your @property is a NSMutableSet you need to look at the Unordered documentation.

373,762 | I'm developing a real-time system by making use of an mbed-OS (RTOS for ARM architecture). I'm not a software engineer and I want to know whether the following solution is practical or not, and how to improve it.
As it is shown in the figure, the elements of software are as follows:
Three different classes (ClassA, ...) describes low level peripherals for gathering data from three different modules which their instances are passed-by-reference to three different Threads (Thread a, ...).
By using three queues (queueA, ...), I'm sending data to the Thread d which is gathering data from the other 3 threads to combine them to form a string in a desired format (synthesis).
The combined data are queued to the Thread e and if some scenarios (Happening in the first three Threads) satisfied, that data is sent to the Thread g.
Now the questions are:
Three first threads are gathering data in different update rates; How to synchronize them in the Thread d?
What is the best signaling solution to aware the other threads (Event or Signal?!)
Is the mentioned architecture practical?
Thanks.

] | There is a level of priority that I feel like you have reversed.
Typically, the software that communicates with the peripheral is the driver level and is the lowest level of abstraction. Drivers do not need to know anything about the logic or data above their level, only how to communicate with the peripherals and where to put the data.
Next above them is more of a manager level. This level communicates with the drivers to grab the data and do formatting, perform sorting, or any other type of algorithms.
Above them, is the application level. This level is typically used as overarching state manager or any "business" logic.
[](https://i.stack.imgur.com/mgO3u.png)
Hardware interrupts are better equipped for handling low level peripherals, such as an ADC or comm device, instead of having an RTOS thread/task. Handling and servicing these interrupts is best handled at the driver level. So "threads" A, B, C would be interrupts from hardware interrupts.
Also, want to point out that I think you mean RTOS tasks, b/c threads can run concurrently and are not **typical** in embedded development.
As your data is coming in, you should have an event/message/flag/signal from the interrupt context to inform the manager task D, that the data is ready for that specific data type. This will keep the interrupt processing to a minimum and lessen the complexity of keeping your code synchronous safe.
A message queue would be best, so you have less fear of losing a message from one of your other peripherals as you are gathering the data from another one.
Another thing to keep in mind, is that you would want to disable the interrupt for the peripheral/driver that you are accessing the data for. Otherwise, you could be moving/copying data, when you receive an interrupt, that manipulates the data you are trying to access, which could corrupt it. Or you need to setup a FIFO circular buffer in the driver, where the interrupt only writes to it, while the manager only reads from it.
Task E would be at application level, waiting for an outside application to request the data, or it provides a service to transmit/broadcast the data for whomever the consumer is.
Im not sure I understand why you would need task F or G.
Sorry if this is a long winded answer, but embedded software architecture is a very large knowledge space. | Understood that the questioner is not a software engineer, but answering the question requires additional and different information that is likely only to be appreciated by a real-time engineer.
The issues that matter from a real-time architecture perspective are the inbound data rates and data sizes and related issues in servicing the components providing the system with data (do they have buffers and deadlines?); scheduling characteristics of the CPU hardware; the way the OS handles priorities; tolerance for data loss; any deadlines in aggregation that this system has to meet, etc.
In the real-time context, "threads" and "queues" is far too high level, one needs concrete numbers and components. |

================================================
As others have mentioned, there are several possible plural forms of *status*.
* *statuses,* regularly formed using the English plural suffix -(e)s. This is listed in various dictionaries e.g. [Collins English Dictionary](https://www.collinsdictionary.com/dictionary/english/status), [Merriam Webster](https://www.merriam-webster.com/dictionary/status).
* *status,* taken from Latin. This is listed in a few dictionaries e.g. the Oxford English Dictionary (which actually gives three forms):
>
> Pl. (*rare*) *status* /ˈsteɪtjuːs/, (now usu.) *statuses* /ˈsteɪtəsɪz/, (*rare*) *statusses* /ˈsteɪtəsɪz/.

It’s not objectively better to use the Latinate plural form, or to try to pronounce it similarly to the way the Romans did. *Status* has been an English word, not just a Latin word, for a long time now. Latinate plurals ending in *-us* are rarely used in English, and in fact, several usage guides say the English form *-uses* is generally preferable.
The original *Dictionary of Modern English Usage* by H.W. Fowler, 1926 (as reproduced in the new 2009 edition) says in the entry for "-us":
>
> Many [words ending in "-us"] are from Latin fourth-declension words, whose Latin plural is *-us* (pronounced ūs); but the English plural *-uses* is almost always preferred, as in *prospectuses.*
>
>
>
The contemporary usage guide writer [Bryan Garner](https://en.wikipedia.org/wiki/Bryan_A._Garner) wrote the following passage:
>
> **nexus.** The acceptable plural forms are *nexuses* (English) and *nexus* (Latin). Naturally, the English form is preferable—e.g.: "The *nexuses* of activity for both rooms are the counters where the marijuana is dispensed." Glenn Martin, "The Tokin' Joint," *S.F. Chron.,* 24 Aug. 1997, at Z1. Some writers have betrayed their ignorance of Latin by writing \**nexi,* as if it were a second-declension noun.

To me, it seems simpler to just go with the regular English plural *statuses,* but if you prefer to use the Latinate plural *status* for whatever reason, you’ll have to make some additional choices about pronunciation (it doesn't seem obvious to me [how to pronounce it](https://english.stackexchange.com/questions/427877/how-are-plural-forms-like-status-pronounced)).
Words that inflect similarly
============================
Some other English words that inflected in the same way as *status* in Latin are
*apparatus, coitus, fetus, flatus, hiatus, impetus, meatus, nexus.* |

*apparatus, coitus, fetus, flatus, hiatus, impetus, meatus, nexus.* | I see some references to status as uncountable as well, but that doesn't make much sense to me.

29,757 | [Rite of Passage](https://gatherer.wizards.com/Pages/Card/Details.aspx?name=Rite%20of%20Passage) gives creatures I control a +1/+1 counter whenever they are dealt damage.
If a 1/1 creature was dealt one damage, would it be sent to the graveyard first or would the creature be saved by getting a +1/+1 counter? Is the same true for being dealt one damage by combat?
My opponent and I had 1/1 spirit tokens and I also had rite of passage under my control and whenever I blocked his spirits with mine, he insisted that they have been dealt damage, therefore their toughness is brought to zero and they die before receiving a counter, but I argued that rite of passage's ability triggers instantaneously and they become 2/2 with a given counter, then he said "if that were true, that would be op".

] | You opponent was correct and the creature will die.
In Magic the Gathering there is virtually nothing that "triggers instantaneously". With the exception of abilities that only create mana all abilities go on the stack. There are a few [special actions](http://mtgsalvation.gamepedia.com/Special_action) that a player can perform that do not use the stack as well, but these are not considered "abilities" by the games rules. Also if there is an effect that says to do something "instead of" something else then the new action will occur when the original would and not go on the stack.
None of these exceptions are relevant here so when combat damage happens the the trigger will go on the stack, then state based actions will be checked and the creature will die before the ability resolves or any player gains priority. Even if you had a special action you could perform that would save the creature it will be dead before you have a chance to do it. | All triggers\* use the stack. While the +1/+1 counters will be triggered, before you get a chance to put the triggers on the stack State Based Effects will be checked and your 1/1 tokens will be put in the graveyard. Once that is done you'll put your triggers on the stack but they aren't going to have much effect, it's too late to save your tokens.
\* There is a minor exception that Fr33dan's answer mentions, triggered mana abilities skip the stack and just resolve. This isn't relevant to the question at hand. |

] | There is **no difference** between the two. Both mean the same. | Strictly speaking, both are correct, and both mean the same thing, but I think that "I used to live in Prague 5 years ago" is slightly awkward; for a verb like "live", the "5 years ago" makes the "used to" unnecessary.
Without the "5 years ago", or other contextual indication of time, "used to" would definitely be better: "I used to live in Prague", not just "I lived in Prague". |

] | *Used to* refers to a state or habit in the past, whereas the past tense describes an event at a particular time in the past. That means that the first sentence would be unlikely because a state or habit cannot normally have such a specific time reference. *I used to live in Prague* on its own is fine, but if you wanted to specify when you lived there, then the second sentence is what you’d use. | Strictly speaking, both are correct, and both mean the same thing, but I think that "I used to live in Prague 5 years ago" is slightly awkward; for a verb like "live", the "5 years ago" makes the "used to" unnecessary.
