] | You will definitely want to choose a standard network layer. I've seen some cases where people have rolled their own, and frequently the protocol is inefficient, and in the end it's a waste of time. A proven network layer provides basic functionality to solve most of the problems you'll likely face in networking with an embedded device, and that will save you precious time and money in the end.
I have familiarity with CANopen, so I'll put a bit of an explanation in here and it might help you decide if that's the way you want to go. If it doesn't fit what you need to do, I'd look at something else.
CANopen is very data centric. All CANopen slave nodes (things you control from a master node, like sensors or motor drivers) provide a dictionary that contains all configuration, control and data-acquisition data you need to read/write to get your job done. You can then read/write these objects individually via the SDO (service data object) mechanism, or read/write these objects periodically in timed CAN message transmissions via the PDO (producer data object) mechanism. Startup, shutdown, and reset, and heartbeat/node-malfunction detection are provided from NMT services, as well as a node ID assignment service (if you wish to use it). To implement a device using an embedded CANOpen library, you basically setup an object dictionary, setup PDOs to periodically send/receive data updates, and write user code that behaves based on those data entries. There are other things CANopen provides, but that is the bulk of it. [Read this book for more info.](http://www.canopenbook.com/) | I write code to access the CAN bus on GM cars, which uses a mostly proprietary network layer. Have you looked into OpenCAN? I would choose an open standard such as CANOpen or even OpenCAN. It really depends on the level of control and flexibility you want in your automation environment. |

] | Sight read more! The best way to get better at doing something is to practice it. Force yourself to keep your eyes glued to the page. Play slow, deliberately, and correct your mistakes. | There are a couple of things you should consider when sight reading:
1. As with any skill you need to start very slowly in order to build the physical and neurological mechanisms to operate faster and more competently. And when I say slow, I mean 30 or 20 BPM. If you have never payed with a click I suggest you begin to learn and as you get used to it, it will start act as a guiding hand, sharpening your timing and sense of rhythm. This leads me to my next point.
2. You know all the notes on the staff and that's great but how is your knowledge of rests? Knowing when not to play is as important as knowing when to play. Learning typical rhythmical groupings is also important because then you can view these groupings as single entities rather than as a collection of individual notes. I suggest you youtube drumming tutorials that have sheet music accompanying their instructions. You'll get a better sense of what I mean then. If you develop strong sense of timing and rhythm, irrespective of the key, melody etc.., and begin to see note placement patterns at first glance, you'll have moved a good way down the road of becoming a competent sight reader.
3. When you say you play it carefully once through and then memorise it, are you really playing it through or do you make a ton of mistakes on the first attempt and then begin studying the piece, foregoing any other sight reading? Improving at sight reading should be a long term goal with consistent observable progress. The little aphorism of 'little and often' should become your mantra - do a little bit of sight reading often. How often? Well, if you do twenty minutes of practise everyday devote 2-5mins to sight reading. Short focused blast of deliberate and intense concentration that will find satisfying and beneficial to your practise.
How little? Try one to four bars of music and then move on. Make mental notes of your weaknesses (you missed the rest, I can't read those ledgers lines, You've never seen so many accidentals!). Wash rinse repeat daily or whenever you practise ;). Consistency is King.
The torture of sight reading through 32 bars when trying to develop the skill should only be inflicted on you by your teacher.
4. A little lesson plan for one bar of music to sight read in 4/4 at 120BPM:
You have 30 seconds to before you need to play:
(0-10 seconds): identify time signature, key and tempo. Mentally play the main scale or mock-play it (think of Adrien Brody in the Pianist). If there are awkward notes (accidentals and sharps for example) rest your fingers on them for a moment and internalize the fact that you will have to play them at some stage.
(10-20 seconds): hum the rhythm (or melody) of the piece while mock-playing what appears to be the supporting notes.
(20-25 seconds): Mock play the first phrase/chords/notes while looking ahead to the next.
(25-30 seconds): Steady and set yourself.

66,328 | I am a Trinity grade 5 pianist and have been playing piano for 2-3 years(earlier played keyboard).
I find very difficult to sight read. I usually play the passage once very carefully and memorize it well so I don't have look at the music while playing. I play while continuously looking down at the keys and find it difficult to lift my head up and register the notes and then play. I know all the notes on the staff, but I can't register them in time to play them on the spot.

] | As with anything, it will improve with practice. And, as with anything, *you should tailor your practice to the problem you're having*.
Since your problem is looking down at the keys, devise a practice method that prevents you from doing so. My teacher growing up always held a notebook above my hands so that I couldn't look at them. Do you have someone in your household or school that would be willing to do that for the 10 minutes a day you practice your sightreading? If not, you could always try rigging something to blog your view. (Or you could really be ridiculous and get one of [these](https://rads.stackoverflow.com/amzn/click/B076VYRT1B).)
Once you've mastered this, you may eventually have a problem with not looking ahead while you sightread; to address this, have someone cover up the current chord you're on, which forces you to look ahead. And so on.

I'm doing Grade 3 exam piano pieces but my sight reading is poor. I suppose it can be explained. I spent many hours practising and polishing pieces. Comparatively, I worked relatively little on sight reading. I'm now evening up the emphasis and I hope it will pay dividends.
To train, I think you have to avoid becoming familiar with the music. So I have bought lots of short exercises (over 100 in all) and I play them at random. If I am in danger of knowing the music to the point where I can play from memory, I stop playing it for a few weeks which usually does the trick. This is different from reading the notation as one would the text in a book. I really want to develop the skill where you read the notation and hear the music in your head without playing a note on the instrument.
There are various method books, YouTube videos, phone apps and books of practice pieces at the right level out there. I had to experiment to find what worked for me. I have not found a magic method that doesn't require a lot of work. I'm on my third method. It has taken me a while to get here. I am now happy enough with the method that I decided to stop looking for a better (magic) method and just get on with it.
I set myself an aim to practice for at least 20 mins every day. It takes a lot of mental effort, so I make sight reading practice the first exercise of the day. If it goes well I might do more; if it goes poorly I might go back to simpler exercises or stop after 10/15 mins if my head just won't take it in. I found sight reading exercises too hard to be tacked on to the end of practice after working on exam pieces and technical exercises.
Hope this is helpful for you. |

Hope this is helpful for you. | I'm going to approach this answer from a different perspective, my own. For years I had trouble sight reading because it took more time to focus on the notes and be certain of their place on the stave. I have problems with my sight where I see double images when I look at things from certain angles so I can see double notes, double staves etc. when trying to sight read. Very confusing when sight reading. I had my eyes checked by several doctors with no solution, but I kept trying and finally found a doctor who knew the solution. He tested me, gave me a new prescription for glasses and now I don't see double when I'm wearing them. If your problem stems from eye problems, you'll need to get that fixed before you do anything else. |

Hope this is helpful for you. | I know this is an old thread. But just do a lot of sight reading every day and constantly add unfamiliar pieces - stacks of sheet music that have nothing to do with the pieces you’re practicing. It’s actually a lot of fun. Pretty soon you’ll notice yourself instinctively able to find a lot of keys without looking. Also do scales without looking. You can isolate larger jumps and do them repeatedly without looking until that jump is easy. Soon you will notice you can play a lot faster if you don’t have to take your eyes away from the page, which makes you lose your place in the music. I also found Hanson exercises great for this if you play them just slow enough that you can take the time to recognize each note and keep your eyes always on the page. |

] | Nitrogen Balance is just how you measure overall nitrogen accumulation, which is a pretty reliable indicator of muscle growth; positive NB is more amino acids staying on your body than pissed out (muscle growth) and negative NB is the opposite.
According to the International Society of Sports Nutrition, a protein intakes of 1.4-2.0 g/kg of bodyweight (0.6-0.9g/lb of bodyweight) for physically active individuals is not only safe, but may improve the training adaptations to exercise training. [1]. The American Dietetic Association, Dietitians of Canada, and the American College of Sports Medicine also support high protein intake for active individuals [2] in the range of 1.2-1.7 g/kg of bodyweight (0.5-0.8 g/lb of bodyweight).
The reasons for the above tend to be increased leucine oxidation (a marker for amino acids being used for fuel, by being turned into glucose) that requires a higher intake of amino acids to negate and **preserve nitrogen balance**. [3][1] Additionally, increasing protein intake above the previously defined RDA 'daily allowance' will increase protein synthesis and, at levels higher than double this total, decrease protein breakdown. [4] Increased muscular hypertrophy is seen as beneficial to sports performance.

However....
===========
You are massively over-thinking your food. As a beginner to weightlifting you will lose fat and gain muscle during a calorie deficit. However, as you progress past "beginner" and linear progressions no longer work for you, you should re-evaluate your diet and consider eating at a maintenance calories (if you want to maintain) or at a 'bulk' (surplus calories).
Option's are divided as to the "optimal" macro-nutritional breakdown and current advice does not go into finer detail because only you know your body and how it is feeling and so only you can plan your dietary needs accordingly.
For example, I went hard last week at crossfit and so I ate more this weekend to give me some fuel and protein to recover.
In terms of splitting up fat and carbs, just split however you want. More carbs will give you more energy but less overall food in your mouth. | Positive nitrogen balance is an indicator of you being in an anabolic state, meaning you are synthesising protein.This is only an indication of what the protein in your body is being utilised for.
If you are taking on too little carbohydrate, your body will utilise both protein and fat for energy; resulting in negative nitrogen balance. You are then likely to be in a state of catabolism, meaning you could be losing lean mass.
For strength training athletes, 2g protein per kg of body mass is a good starting point for protein synthesis. Any intake above 2.4kg body mass is considered to be of little benefit for gains in muscle mass.
Both carbohydrate and protein will add 4kcal per gram to your diet, fat will add 9kcal per gram.
Good fats are essential in your diet but are costly in terms of energy, aim to keep total fat below 20% of total energy allowance; aim for monounsaturated and polyunsaturated fat sources, avoid saturated and trans-fats.
Focus on the intake of complex carbohydrates i.e brown rice as opposed to simple carbohydrate i.e. white bread. Read about glycaemic index/glycaemic load and how it relates to exercise. Timings for the intake of different types of carbohydrate will make a huge difference to outcomes. If you time carbohydrate intake effectively, you can worry less about anabolic windows post workout.
As a rule of thumb 3500kcal is equal to one pound fat. Aim to lose between 1 and 2lbs per week when stripping, any more and you will likely sacrifice lean mass. Be patient, it pays to be conservative.
**REMEMBER:** protein is expensive fuel, train smart.
Focus on building a good feedback loop: record what you eat, and your training outcomes. Tweak ratios for what works for you, there are no hard and fast rules and good science will lead you where you want to go. The above are good starting points. |

It's part of the Very Short Introduction series, not as expensive as Blackwell's, and takes you through just enough history to help you understand what the relevant issues currently are.

Also, a good essay to start with is always Thomas Nagel's "What is it Like to Be a Bat?" which you can [easily find online](http://organizations.utep.edu/portals/1475/nagel_bat.pdf). Hume and Berkeley are worth reading, but they're a little removed from the current state of the debate on minds and consciousness. If you want something that's not dense, but you're not afraid of a longer read, there's also Stephen Pinker's [How the Mind Works](http://rads.stackoverflow.com/amzn/click/0393334775). It's a fairly strong Functionalist account of mind, but it doesn't pretend to have all the answers. | To be honest, it is hard to recommend a single book. If you really want to understand philosophy, you must read many books. So you might want to start with Hume's **Enquiry Concerning Human Understanding**, Berkeley's **Treatise Concerning the Principles of Human Knowledge**, Descartes' **Meditations** and **Discourse on the Method**, as well as Kant's **Critique of Pure Reason** and **Principles of the Metaphysics of Morals**. These are by far the best epistemology/metaphysics books I have ever read. It might seem obvious recommending such well-known books, but they are well-known because they are truly phenomenal. Also, if you are interested in the development of mathematics, and in particular analysis, I would recommend **The Analyst** by Berkeley -- a remarkable book. If however, you do not have time to read them all, start with Hume's **Enquiry Concerning Human Understanding** and Berkeley's **Treatise Concerning the Principles of Human Knowledge**, and avoid Kant' **Principles of the Metaphysics of Morals**, and any of Kant's books because they are very difficult to read. You need to read each book at least twice to understand Kant. |

It was a series of science fiction short stories that illustrated various thought problems in consciousness, followed by the two authors discussing the implications of the story. For someone just getting their feet wet in philosophy, it is a great easy introduction.
The best single book on philosphy of mind I have read is Blackmore's A Very Short Introduction to Consciousness. It is VERY SHORT, with very clean writing. It is also focussed on compiling the evidence that has a bearing on the viability of consciousness theories. Blackmore takes one through this evidence, and with a general dialog between dualism, materialism, and her preferred delusionism viewpoint. Blackmore would probably be best read after one has at least skimmed a general overview book on philosophy of mind, although one could read her first, then the overview second. | I have been studying (in my on spiritual quest) the topic of consciousness for more than a decade and I find that most of the stuff on consciousness severely lacking for two reasons. 1) it is too scientific and 2) it is too New Agey. I stumbled across a book last year that was a free download by an unknown author and the book just blew me away. The book is called "Demystifying the Mystical" by Endall Beall.
A few months back I saw that this author has created a series called the Evolution of Consciousness and I immediately purchased the books through Amazon. The first book is good and it takes on Philosophy and brings a new light to the field. The second book is called Willful Evolution and it makes so much sense and is more practical, not scientific or New Agey. Actually and the Demystifying the Mystical book (which demystifies what most people think of as mystical) so it kind of tears the New Age apart (with good reason). There are more books to the series that I am looking forward to reading. |

95,952 | *Situation:*
I have recently been offered an engineering job with a silicon valley tech company, contingent upon a pending background check. Everything seemed fine until they ran a background check. It turned up a 5 year old traffic violation for driving without insurance. I had completely forgotten about this and was surprised to find this on the background report. I was never arrested or imprisoned or appeared in court, simply paid a 250 dollar fine. I learnt just now that the offense is classified as a misdemeanor in that state. I haven't been contacted by the company on this matter yet, I just got the background check report from the reporting firm a couple of days ago. I would also add that I don't remember answering any background related questions at any point during the application process.
*My questions are as follows:*
1) Do you think companies might take back job offers for something like this. My job is related to software and does not involve driving.
2) What is my best course of action right now? Should I proactively follow up with the company myself or stay put until they say something? (I have to give my two week notice to my current employer soon) | 2017/07/26 | [

] | I don't think most employers would care if you committed a small misdemeanor like that. I've violated an ordinance or two in my day and seem to get employed just fine.
Don't say anything. It would come across as paranoid. If they *do* bring it up, explain the circumstances, but don't make a big deal of it. As always, until you accept the offer, continue your job search. Congrats on the offer! | No. Maybe they'd care about a DUI, but probably not even that if you're in recovery. Your violation doesn't effect your ability to work and doesn't show major failures in judgement or honesty. They're looking for felonies- theft, embezzlement, murder, rape, assault. Misdemeanors don't matter, traffic violation definitely don't. Who doesn't have a speeding ticket or two in their history? All failure to have insurance means is you were broke. |

So yes, if this is the announcement, you need to provide this info, and it needs to go into your BioSketch. Whether you need to use the (ugh) new biosketch format or not, I can't tell you.
The best advice is to ask the office at your school that coordinates sponsored research, as well as have a chat with the program officer involved with this PA at the institute you would be applying to. | Each NIH grant comes with extensive guidance. For the [Ruth L. Kirschstein National Research Service Award Individual Predoctoral Fellowship to Promote Diversity in Health-Related Research](http://grants.nih.gov/grants/guide/pa-files/PA-14-148.html) the guidance says

In general, it is advisable to talk to the Program Officer at the NIH whenever you are considering applying for a grant/fellowship.

It works great in Vista and 7.
[Vista Battery Saver](http://www.codeplex.com/vistabattery) has a lot more features and can give you a bit more fine grained control.

Nevertheless, I still often find myself with over 20 tabs open at a time, just because apps that I use in the course of the day that I don't want to keep opening and closing and have them be in different positions.

674,854 | I have seen several debates on different forums but could not reach to a solution.
My notebook has a UHD display running windows 8 as host OS. I have tried Vmware and virtualbox as VMs to have the experience of Ubuntu 14.04 as guest OS. The problem is with the screen resolution I get in the VM, either on a full screen or in any other view size. It's nano and awful.
My question specifically is: Is there any VM which supports Ubuntu 14.04 in such a way that we can control the resolution with the best results for user on any notebook with a UHD display?
**OR**

Therefore install Vivid or Wily and have patience and in any case, install the guest addons, e.g. *VMware Tools* and/or Oracle *VM VirtualBox Extension Pack*. | If you run a VM on Windows, then run a host within the VM, the display drivers presented to the host, are those of virtual hardware created by the VM. Your host, will have no idea you're running a UHD display, unless you could pass the whole device to the host (which could only be done, if the actual running OS, windows, was using a different display device).
I believe if you use VMWare, and have VMware tools installed in the host, you can resize the VM screen, like a regular desktop window. Without tools, you have to specify the display resolution in the vm config file. Looking at an Ubuntu VM I have running under Workstation 10, I can emulate up 10 monitors, each with up to a 2560x1600 resolution. I'm not sure how to have those multiple monitors display on my physical host, but it must be possible.
But remember when you run under a VM, you're not running on your actual machine, the host is running on a virtual host, which you can design as you wish, with whatever hardware you want. If you want to emulate a UHD display, in the host, you'll need a VM that can emulate one (I was unable to find one given a cursory search in google).
If you're just trying to run Ubuntu in full resolution, did you try running rebooting the system to use Ubuntu on a Live CD. It will then use whatever drivers it has installed to use your UHD display, as much as it's able. With the Kubuntu live CD, I've installed Nvidia drivers and tested out a full x display, to be sure the hardware could support running my desktop, before re-installing. Live CD stores modifications to the virtual hard disk in memory, so you have the perception of a normal running machine, without actually touching the existing HD. |

I suppose people keep doing it because they don't know any better or don't care.
Will a parser be any better? Maybe, maybe not.
I maintain that sending a verification e-mail is the best way to validate it. If you want to check anything from JavaScript, then check that it has an '@' sign in there and something before and after it. If you go any stricter than that, you risc running up against some syntax you didn't know about and your validator will become overly restrictive.
Also, be careful with that TLD validation scheme of yours, you might find that you are [assuming too much](http://www.bizreport.com/2008/07/icann_anything_is_the_next_domain_craze.html) about what is allowed in a TLD. |

The only real way to be sure is to get a confirmation email, but the problem is only to give a fast response to the user before the confirmation process takes place. That's why it's not so important to be strictly compliant.

This is not true. For example, "ben..doom@gmail.com" contains only valid characters in the name section, but is not valid.
In languages that do not have libraries for email validation, I generally use regex becasue
1. I know regex, and find it easy to use
2. I have many friends who know regex, and I can collaborate with
3. It's fast for me to code, and me-time is more expensive than processor-time for most applications
4. For the majority of email addresses, it works.
I'm sure many built-in libraries do use your approach, and if you want to cover all the possibilities, it does get ridiculous. However, so does your parser. The formal spec for email addresses is absurdly complex. So, we use a regex that gets close enough. | Regexps are much faster to use, of course, and they only validate what's specified in the RFC.

] | People do it because in most languages it is way easier to write regexp than to write and use a parser in your code (or so it seems, at least).
If you decide to eschew regexes, you will have to either write parsers by hand, or you resort to external tools (like yacc) for lexer/parser generation. This is way more complex than single-line regex match.
One need to have a library that makes it easy to write parsers directly in the language X (where 'X' is C, C++, C#, Java) to be able to build custom parsers with the same ease as regular expression matchers.
Such libraries originated in the functional land (Haskell and ML), but nowadays "parser combinators libraries" exist for Java, C++, C#, Scala and other mainstream languages. | People write regular expressions because most developers like so solve a simple problem in the most "cool" en "efficient" way (which means that it should be as unreadable as possible).
In Java, there are libraries to check if a String represents an email address without you having to know anything about regular expressions. These libraries should be available for other languages aswel.
Like Jamie Zawinski said in 1997: "Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems." |

] | Regexs that catch most (but not all) common error are relatively easy to setup and deploy. Takes longer to write a custom parser. | I don't believe correct email validation can be done with a single regular expression (now there's a challenge!). One of the issues is that comments can be nested to an arbitrary depth in both the local part and the domain.
If you want to validate an address against RFCs 5322 and 5321 (the current standards) then you'll need a procedural function to do so.
Fortunately, this is a commodity problem. Everybody wants the same result: RFC compliance. There's no need for anybody to write this code ever again once it's been solved by an open source function.

422,731 | I would like to control my AC with a Raspberry Pi. My system is similar to [this one](https://www.seeleyinternational.com/artefact/breezair-exq-ezq-exs-evaporative-controllers-manual/), although it is an older model from 2004.
Currently the system has a **wired** controller. There is no bluetooth, wifi, IR or RF. A wireless controller can be [purchased](https://www.ebay.com.au/itm/Breezair-Remote-Control-Horizon-107950-/192324663089) for AUD$500 which would also require a [receiver](https://rockhamptoncoolingsolutions.com.au/products/103587-breezair-rf-receiver) to be purchased separately.
I would like to interface a Raspberry Pi with the current wired controller instead.
I need to understand how to activate the contact pads electronically, but I have very limited knowledge in this area. I'm hoping that based on the images attached below, people are able to help me wire it up.
The controller has six buttons but 12 contact pads - two per button.
I will update this question to be more specific once/if I have details.

] | If you look at the annotated picture below I think we can all agree that all of the button finger contact pads share a common connection with each other (yellow lines) which are likely to all connect to the GND or the VDD of the control circuit. You will have to use a digital meter to probe the circuit to measure voltages and figure out what this common connection is.
The next observation is that each side by side pair of the contact finger pads are tied together on the other side (added blue lines). This is most likely to be done to provide for redundancy and can be confirmed if the remote just has six user button functions instead of twelve functions. All evidence seems to indicate 6 functions.
The next key thing that you will have to do is to determine if it is even safe to hack this wired remote. Being that the remote wires into the guts of the A/C unit it is going to be difficult to figure out if the "GND" of the remote would be safe to wire up to the externally powered Raspberry Pi it is going to be highly recommended that you use opto-couplers to interface between the Pi and the remote so that you can maintain a safe isolation. Beyond even safety there is the additional concern that if you did try to direct tie the GNDs between the remote and the PI it is possible that the A/C could fail to function properly - even more reason to think about using opto-couplers to control the button functions.
For the sake of further discussion here lets say that you have determined that the common (yellow lines) of the remote is indeed the GND and the other side of the paired switch finger pairs is found to be sitting at a positive voltage above GND when the contact fingers are not connected. The following diagram shows how to kludge in the opto-coupler to the remote key pad for one switch override function. The shown part number is one that I have used as it is a very efficient opto coupler that will fully turn on the output NPN transistor with as little as 1mA drive from the GPIO of the Pi microcontroller.
[](https://i.stack.imgur.com/1nZPV.png)
If the common buttons connection (yellow lines) happens to be the VDD of the remote and the blue line side of the button fingers sits at a lower voltage when the button fingers are not connected then you will want to swap around the NPN transistor Collector (pin 4) and the Emitter (pin 3) connections into the circuit.
In any case as shown an high level programmed onto the Pi GPIO will activate the NPN transistor to provide a short across the associated button finger contacts. It will likely be necessary to keep the Pi GPIO active for a period of 50msec or even 100msec to ensure the remote registers the signalling. The controller in the remote most likely has a switch debounce filter built in that has requires this length of active press time. | What is your goal here? For example, if your goal is to control the AC with the RasPi, I would first suggest finding out how the remote unit controls the AC. Options are RF signals, IR signals, and specialized RF such as Bluetooth or BLE. What I would do is figure out what the control mechanism is, and then add that as part of the RasPi circuit.
If it is IR, you need to know what wavelength and modulation frequency are used. A TV, for example, uses 940 nm with a 38 kHz modulation frequency. One way to test this is to spend a couple dollars to buy an IR receiver (NOT an IR-sensitive photosensor) device (e.g., www.adafruit.com search for item 157, $1.95). If it indicates reception of the AC remote, then your AC is running 940 nm/38 kHz. I did not see, in the photos, a Bluetooth, BLE, or WiFi antenna (a little zigzag trace), or anything with an FCC certification label, so I suspect IR. You can find IR receivers with other wavelengths and modulation frequencies at Digi-Key, Mouser, etc. You need to measure pulse widths to a few microseconds, and there are a number of standard protocols in use. If you discover that IR is the technique used, contact me here and we can discuss circuit design and software. For example, if it is IR, you need a 940 nm IR diode and the ability to create the same modulated waveforms as the buttons produce. This may be trickier on as RasPi than on an Arduino, or Cortek M-series chips, because the OS is going to make your life miserable.
For example, we are currently generating a 9 ms-long 38 kHz "start" signal. The signals become self-clocking, with a 528 us 38 kHz signal followed by 528 us of "silence" to mean 0, or 1056 us (2x528) to mean 1. Each 2-byte command (b1,b2)nis encoded as 4 8-bit bytes
[b1, ~b1, b2, ~b2]
where the complement of the byte allows simple error checking. Pushing a button sends out a sequence of "button n pressed" messages, so even if a few are rejected due to noise, one will get through. Redundant messages are ignored until the next 9ms "start" signal.
Different remotes use different protocols, but they all resemble each other. Example, another protocol sends
[b1, b2, ~b1, ~b2]
It is insufficient to have a simple IR detector; the one I cited only responds to signals indicated by the 38 kHz carrier. This eliminates effects of room lighting, sunlight, steam irons, red-hot pokers, etc. |

In simple words, shell is a software which takes the command from your keyboard and passes it to the OS.
**So are konsole, xterm or gnome-terminals shells?**
No, they're called terminal emulators. They open a GUI to interact with the shell. You can think of them as a **frontend** to the shells.
[](https://i.stack.imgur.com/hKEfU.png)
**Different Shells**
There are different shells which are more or less same but the features and syntaxes are different.
**Bourne shell** The most basic shell available on all UNIX systems
**Korn Shell** Based on the Bourne shell with enhancements
**C Shell** Similar to the C programming language in syntax
**Bash Shell** Bourne Again Shell combines the advantages of the Korn Shell and the C Shell. The default on most Linux distributions.
**tcsh** Similar to the C Shell | The shell is the program that runs in the terminal, that reads the commands you type and executes them.
Unix and Unix-like operating systems today offer a choice between mostly the same set of shells, because these shells pre-date most of those operating systems.
For further reading I recommend [Evolution of shells in Linux (IBM)](http://www.ibm.com/developerworks/library/l-linux-shells/)
Edit to add information regarding shells and terminals following comments on another answer:
A [terminal](https://en.wikipedia.org/wiki/Computer_terminal#/media/File:DEC_VT100_terminal.jpg) is a hardware peripheral that interfaces with a human, it is composed of output to the user and input from the user, in other words of a screen and a keyboard, see link. What the GUI shows you is a *virtual* terminal. The shell is the command-line interface software that is usually what you see on a terminal, but it doesn't have to be a shell. You could start up a virtual terminal and tell it to run `vi` directly, for example, no shell involved. |

] | To "clock" something is idiomatic so it's not necessarily OK to use as a substitute for the more generic "to time" something. It does convey an image of timing with a stopwatch or some other precise chronometer, so measuring things like swimmers or race cars or solving the Rubik's Cube is fine, since those are activities where more speed / less time is wanted.
But when talking about something like a research paper, it's weird. The image is someone standing over your shoulder while you study, stopwatch in hand, urging you to "read faster!"

What I mean is here that I looked at the clock when the process started and I looked the clock again when the process finished. However I did not measure time in a scientific way using millisecond unit like in a spring. | 2017/01/03 | [

] | To "clock" something is idiomatic so it's not necessarily OK to use as a substitute for the more generic "to time" something. It does convey an image of timing with a stopwatch or some other precise chronometer, so measuring things like swimmers or race cars or solving the Rubik's Cube is fine, since those are activities where more speed / less time is wanted.
But when talking about something like a research paper, it's weird. The image is someone standing over your shoulder while you study, stopwatch in hand, urging you to "read faster!"
Although of course you can use "clock" for comic effect.

We generally only use the verb "clock" when giving instructions, like, "Al, please clock Bill's time." It's rather redundant to say you measured the time and then to give the measurement. Like:
>
> How tall is this stack?
>
>

>

Well obviously if you know it's 9 inches you must have measured it, so saying you measured it is superfluous.
People will use "clock" when they want to make clear that this was a measurement and not a guess or estimate.

The listener can't be sure if that's an actual measured value or just a guess. But:

That indicates it's an actual measurement.
You could also say "I timed it ..." or "I checked a clock and it was ..."
BTW "Half and an hour" is not correct. If you mean 30 minutes, say "half an hour". If you mean 90 minutes, say "an hour and a half". |
36,946,661 | Evening,
I have recently installed TFS2015 and investigating the Release Management integrated solution, but have come across a huge blocker that I just cannot make sense of.
I currently have a RM2013 build working with TFS, RM Server 2013, and Powershell DSC and have setup a new deployment in RM2015, it has a single task in it 'Execute Powershell on Remote Machine' - with a very simple powershell script just writing out a string to the verbose listener.
I have verified that the file is transferred to the Agent working directory as part of the artifact transfer process, and if I call **Import-Module "path to script"** (Which is what the PowerShellonTargetMachines script seems to do under the hood) in the ISE of the remote server, my script runs perfectly fine - but no matter what I do, in TFS release 2015 I get this error without fail:
[error]The term 'path to script\test.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. For more info please refer to <http://aka.ms/powershellontargetmachinesreadme>
=========================================================================================================================================================================================================================================================================================================================
Now just to double confirm, the path to the scrpt is 100% correct, I have pasted it into a local ISE on the remote server, and it executes perfectly fine - but from TFS2015 Execute Powershell on Remote Server - it simply fails to run, in fact any script I point at fails to run with the exact same error (I initially thought it might be a DSC component install failure, but even with a simple test script the same issue occurs without fail!
My path in the tasks Deployment>Powershell Script parameter input is:
c:\test\_scripts\test.ps1
I have tried with quotes, without quotes, dot sourcing - nothing makes a difference which is making me think something fundamentally is either broken with my installation, or I am simply doing this wrong.
Any ideas gratefully received!!! | 2016/04/29 | [

33,472 | So i am performing k-means clustering on RFM variables (Recency, Frequency, Monetary). The RFM variables are in the form of quantiles (1-4). I used PCA and found the PCA components. I then used the elbow method to find the optimal number of clusters and then I use it in the k-means algorithm.
Could anyone guide me if this is a correct method? Further, the clusters I get range on the graph, their axis ranges[](https://i.stack.imgur.com/i3uje.png) from -3 to 3 and I am not entirely sure why it ranges from that way. | 2018/06/21 | [

] | Judging from the plot, **there are no clusters**.
K-means requires continuous variables to work well. The data you have has discrete steps (which causes the grid pattern in your plot).
There is no benefit of using PCA here. Use it only for visualization. The scale -3:3 that you don't understand is from PCA. So you probably have not understood PCA enough either. | Recency, Frequency, and Monetary Value (RFM) are measured on a Likert scale from 1-5. Likert scale variables are not amenable to Principal Component Analysis (PCA) or k-means clustering because those methods assume continuous measurement.
It would be more appropriate to use multiple correspondence analysis (MCA) and k-modes which assume nominal level measurement. |
300,511 | In Super Mario Bros, there is a glitch, where a certain set of frame-perfect presses allow you to jump directly into the bottom block of the flagpole at the end of the level. [In this article on the Mario Wiki](https://www.mariowiki.com/List_of_Super_Mario_Bros._glitches#Flagpole_Glitch), it describes the glitch as:

> The player must jump right next to the block that holds the Flagpole and then jump again. If done correctly, Mario or Luigi will jump onto the flagpole normally, but the flag will remain raised.

> Complete the level without lowering the flag by glitching into the base block of the flagpole and touch the flapole from inside. Doing so is faster than lowering the flag. The points you get from the flagpole will be only 100. This trick isn't used in 8-3 of the warped run, since the timer would turn 343 which results in fireworks.

I found an attempted explanation by the first person to successfully pull off a flagpole glitch in [this thread](https://www.reddit.com/r/speedrun/comments/3pawbn/comment/cw4ubcf). The explanation is for the flagpole glitch on 8-2, so it mentions a Bullet Bill, but the rest applies to the flagpole glitch in 1-1.
>
> Normally when completing a level Mario will grab the pole, slide to the bottom, hop off and walk to the castle. Once he reaches the castle the timer countdown begins. There's actually an invisible block just to the right of the door to the castle that Mario ends up walking into. This block prevents Mario from walking past the castle door, and also triggers the game to hide Mario behind the background making it look like he entered the castle. So the game is constantly checking to see when Mario is walking into a block to do 2 things: hide Mario and start the timer countdown. The trick used in speedruns is to jump on the bullet bill at a specific position in order to temporarily clip into the block that the flag pole is sitting on, allowing Mario to grab the pole and then immediately get forced OUT of the block to the left. Thus, Mario is immediately touching a block, tricking the game into hiding Mario behind the background and to start the timer countdown without any delay, skipping the entire animation of the flag coming down and Mario walking to the castle.

I also found a [tutorial of how to do this in a TAS](https://programming.wonderhowto.com/how-to/skip-level-end-flagpoles-super-mario-bros-tas-415003/) and it even includes a [video](https://youtu.be/tRE3DML9-vA). | I have a bit of an explanation on how to do the glitch in a TAS.
First, on the first frame Mario can jump, hold left+right to get him to accelerate faster, then do a jump immediately while holding B+right. Kill one enemy, wait a few frames and do a high jump. You should be able to do another jump right after, so do it while still holding B+right. If done correctly, one more full jump will get you to the flagpole and end the level. However, on the 22nd or 23rd frame of holding the jump button and nothing else, press Left for one frame. Wait until pressing right won't get the flag to come down, and when the music stops after the A but before the F, press left for 4 frames. On the 4th frame, press jump and you've done the glitch! Hopefully that helps! |

No. I tried to exchange an old banknote at a retail branch of the Banque Cantonale de Genève. The clerk told me I'd have to go to the main office down in the center of town ... or to any post office. I went to the nearest post office, where the window clerk exchanged my 100-franc note without asking any questions, without asking for ID, and without any fee.
The post office accepted these notes through October 2021. It doesn't require much time or effort to try, but I suspect that you might not succeed in changing your notes there anymore. |

The difficulty of using a markup system is that you do not know what will be important in three years.
When you read an article it may be that keywords a, b, and c were what was important to you, but the article contained a seemingly uninteresting reference to keyword d, which is not a keyword because you don't care at this point in time. The keywords do not hurt, but if they cause you to commit less to memory because you say "I can search it," then you actually have lost retrievable data. Of course in an ideal world you would have built a search using the contents of the pdfs.
Pre-built bibliographic tools exist. BibTex is very useful, though not ideal. For continuity I use BibTex though if I were starting today, I may not. I maintain a unified bibliography for everything I have ever used or done. BibTex is part of LaTeX. If you are going to do professional writing, you should probably learn LaTeX. Download something like MikTex and then use something like TexStudio as a wrapper so you do not have to type out all of the commands.

I maintain four inch binders that are organized in a manner that is useful for me. I have my own Dewey system. Electronically, I store the articles using tags as names such as serial\_correlation\_explosive\_roots or mvue\_cauchy\_trimmed\_mean. I also depend a lot upon memory. The difficulty of using a markup system is that you do not know what will be important in three years.
When you read an article it may be that keywords a, b, and c were what was important to you, but the article contained a seemingly uninteresting reference to keyword d, which is not a keyword because you don't care at this point in time. The keywords do not hurt, but if they cause you to commit less to memory because you say "I can search it," then you actually have lost retrievable data. Of course in an ideal world you would have built a search using the contents of the pdfs.
Pre-built bibliographic tools exist. BibTex is very useful, though not ideal. For continuity I use BibTex though if I were starting today, I may not. I maintain a unified bibliography for everything I have ever used or done. BibTex is part of LaTeX. If you are going to do professional writing, you should probably learn LaTeX. Download something like MikTex and then use something like TexStudio as a wrapper so you do not have to type out all of the commands. It isn't bad to learn on MikTex, but it is slower than TexStudio since TexStudio will guess what you are trying to do and autocomplete. |
83,566 | I have finished my M.Sc. in Applied Mathematics in 2016. I wish to pursue a PhD. Currently I am preparing for GATE (Graduate Aptitude Test in Engineering, a master’s-level national entrance exam in India). In this respect, I have a few questions.
1. If I only have a valid GATE score but no CSIR-JRF NET qualification, will I be eligible for the 25 k funding?
2. If yes to above, is this funding available for any NAAC-accredited university (public or private) in India?
3. Is there any written statement from the government which validates this? | 2017/01/20 | [

They found that taking notes with pen and paper is more effective... but, that was because students who typed their notes were copying lectures verbatim whereas students who took notes by hand were taking in the information and then writing it in their own words (thus processing the info at a deeper level).
So, the key is the way you process the information, not necessarily the method you use to take notes. But, at the same time, it is noteworthy (no pun intended) that longhand notes tends to lead to that deeper level of processing more so than does taking notes digitally.
Personally, I'm all about taking notes longhand, and I print out articles that are important to me/my work. | The support is probably the least relevant part. What you actually need is a structure to organise your notes.
If it goes well digitally for you, go for it. At the end, it all depends on how you function. I know that if I need to learn something, I better write it on paper than on a machine, unless it's computer programming. But that might not work for you.
There are multiple tools to manage bibliography, with or without the ability to add notes. Just pick the one you like and can work with. |

Yes you can make that, but it's tricky here by using QOS
So lets say you have 2 routers each one have different WAN IP and both of them gives your PC same StaticIP for both Ethernet/Wireless card
easy for now :P
the next step is using QOS service
On the first router
0 upload
X download
the second one
X upload
0 download
now if you want to browse something your internet explorer will not open any site
The tricky thing is to change the MAC address of your wireless/Ethernet card and make both of them have the same MAC "now people will vote down for this part, because everyone know the MAC not important for web browsing Well some websites like Facebook use MAC address and WAN IP in the same time"
**BUT** you still can't open any site simply because when you enter a domain/site on your browser your browser will send a command to DNS server then the DNS server will connect you to a server to bring the website for you, when you block the download on your first router the server can't send you the site ok you have a mac address but your WAN IP on the second router is different so the server can't know that's you
To solve this problem you need a network MASK to make both WAN-IP work as one address, so you need a DNS server for that :) |

As far as I know, you can't use the Delphi 2009 IDE to maintain Delphi 5 projects directly. For example, even if you stick to functionality that's common between the two, some properties that are not supported in Delphi 5 are written to your DFMs, causing an error at run time.
I've maintained projects and library code that were written in Delphi 2005/2006/2007 that was also being used in Delphi 6/7. I usually edited and debugged these using the latest IDE. I had separate project files for each target version and made sure they all used the same [memory manager](http://sourceforge.net/projects/fastmm/). Finally, I had an automated build process and unit tests that would strip incompatible properties out of the DFMs (my own DFM Scrubber), make sure all of the targets always compile and run unit tests, which are also recompiled for each target.
All in all, it's more effort and I wouldn't recommend it unless you have a specific requirement to do so. | No. That said, it is still Delphi, and assuming you have source or D2009 versions of any custom components it can be modified to compile in Delphi 2009. The layout of the VCL has changed quite a bit since D5, so expect to have to modify your `uses` clauses and probably rewrite some small chunks here and there, but it is doable. |

I suggest you open the project and see where it fails, close the project (without saving anything), find the component versions you need and install them, and once the project opens up in design mode (all components are installed) you can start porting.
Read the Unicode Delphi migration (porting) information available at the website.
Ask your self each time you see PChar, and Char, if it needs to be PAnsiChar, or AnsiChar instead? If you are reading bytes from a disk, a com port, or a network connection, you will need to change from Char to AnsiChar, from PChar to PAnsiChar, otherwise, you might just leave the Char and PChar as they are and they will become Unicode. Always be aware that Char is not a Byte, anymore.
You also must replace explicit references to narrow Win32 API calls with versions without the A (ansi) suffix. Example: CreateFileA might need to become just CreateFile.

On the other hand, a PhD thesis is **not** a scientific journal paper, but a PhD thesis, and if you want to use *I* in it I don't see anything wrong with that.
The passive voice should not be used to avoid writing *I* or *we*. If the entire thesis is written in the passive voice, it is much harder to read, and the sentences within it1 have to be reworded awkwardly so that some good transitions between the sentences within a paragraph are lost. On the other hand, if some sentences seem to require the passive voice, by all means those sentences should be written in the passive voice. But the passive voice should only be used where it is justified, that is, where its use improves readability of the thesis.

] | I don't think there's anything wrong with using *we* in single-author scientific journal papers. It's the tradition, and if you use *I* in scientific papers it stands out, not necessarily in a good way. On the other hand, a PhD thesis is **not** a scientific journal paper, but a PhD thesis, and if you want to use *I* in it I don't see anything wrong with that.
The passive voice should not be used to avoid writing *I* or *we*. If the entire thesis is written in the passive voice, it is much harder to read, and the sentences within it1 have to be reworded awkwardly so that some good transitions between the sentences within a paragraph are lost. On the other hand, if some sentences seem to require the passive voice, by all means those sentences should be written in the passive voice. But the passive voice should only be used where it is justified, that is, where its use improves readability of the thesis.

] | Certainly when there is some kind of 'finish' worn off of a surface the albedo/diffuse texture changes, but what is also important is, as you note, the specular highlight as well as any glossiness or reflectivity. This is normally done with a grey-scale texture used as a mask to make the worn off sections look matte while the pristine areas remain glossy. | Edge effects are generally produced by using multiple surface materials (texture sets) and blending between them with hand-painted or generated edge textures. Note that these materials only exist in the artist's workflow, as they're rendered to a single set of textures for the game.
Textures that may contain edge information are curvature maps and ambient occlusion maps.
You can see how it's often done by artists in this video: <https://www.youtube.com/watch?v=4fCF5HPc5_c> |
