• Naming conventions used for variables and functions in C

  - by Zel

  While coding a large project in C I came upon a problem. If I keep on writing more code then there will be a time when it will be difficult for me to organize the code. I mean that the naming for functions and variables for different parts of the program may seem to be mixed up. So I was thinking whether there are useful naming conventions that I can use for C variables and functions? Most languages suggest a naming convention. But for C the only thing I have read so far is the names should be descriptive for code readability. EDIT: Examples of some examples of suggested naming conventions: Python's PEP 8 Java Tutorial I read some more naming conventions for java somewhere but couldn't remember where.

• Why must I restart for HDMI audio?

  - by David Shochat

  I have a System76 Lemur Ultra laptop, which has an HDMI port. When I plug in the HDMI cable, it is recognized immediately for video, but not for audio, i.e., it does not show up in the Output tab of the Sound Settings dialog. However, if I do a full restart with the cable plugged in, then it does show up and can be selected. I've also discovered that manually killing and restarting pulseaudio with the HDMI plugged in will force it to be recognized as an available audio output. So my question is, what is broken here? I've thought about writing a bug in launchpad, but I don't know which component is malfunctioning. Is it the kernel? ALSA? Pulse Audio? Something else? By the way, the same bug seems to exist in reverse, namely if I disconnect the HDMI, it is still listed in the Output tab until I again restart the OS. This is 12.04 LTS.

• Which logfile(s) log(s) errors reading a cd?

  - by Robert Vila

  I introduce a CD-RW, maybe blank (I really don't know), and after a little movement inside the reader, the CD is ejected without any message at all. I would like to know what is going on and the reason why it is ejected. How can I know that in Natty. The CD reader is working OK because I can read other CD's. It only gave me problems writing from Natty, a few days ago, but with MacOS there was no problem. Thank you Edit: Maybe there is no error, but then, how can I know what is in the Cd if there is anything?

• Best strategy (tried and tested) for using Box2D in a real-time multiplayer game?

  - by Simon Grey

  I am currently tackling real-time multiplayer physics updates for a game engine I am writing. My question is how best to use Box2D for networked physics. If I run the simulation on the server, should I send position, velocity etc to every client on every tick? Should I send it every few ticks? Maybe there is another way that I am missing? How has this problem been solved using Box2D before? Anyone with some ideas would be greatly appreciated!

• What can I put in my software development blog to make it a good showcase of me?

  - by Sean

  I have been itching to write a software development blog for some time now. The best advice I've received about blog writing is "Write the blog you would have want to read". Its good advice but its only half the story, Once you write a blog it becomes your showcase on the Internet, it is bound to come up on any search conducted by a future colleague or employer. It can be a good thing or it can do some serious damage. So if there are any hiring managers out there, can you give me a few pointers on what it is in a blog that give you a good impression about candidate and/or the kind of stuff that causes you to throw the candidate's resume to the nearest bean? Does a blog have to come up with a clever piece of code every week? (Don’t think I can manage it) Is it OK to blog more then not about development methods to improved quality and productivity (have a lot of ideas about that). Can I blog about stuff I did not try first hand but seems noteworthy?

• What are the so-called "levels" of understanding multithreading?

  - by Dan Tao

  I seem to remember reading somewhere some list of 4 "levels" of understanding multithreading. This may have been in a formal publication, or it may have been in an extremely informal context (even like in a Stack Overflow question, for example). Unfortunately I don't remember who referred to them or precisely what they were. I seem to recall that they were roughly like: Total ignorance Awareness mixed with incompetence Relative competence mixed with fear True understanding My intention is to refer to these levels in a blog post I'm writing, with a reference; but I can't for the life of me remember where I first encountered this list. Brief Google searches have proved unfruitful.

• What are your programming idiosyncrasies?

  - by EpsilonVector

  I noticed that I have a peculiar habit of finishing every line with a space. It carries over from my prose writing where a paragraph can have multiple sentences and so it is very common to follow a period with a space, and I end up doing that automatically for every period (or when it comes to programming- semicolon). It started out as something automatic, but I'm so used to this by now that if I miss the space it actually bothers me and I end up returning to that line to input it. What are some of your programming idiosyncrasies?

• Seeking questions about creating Microsoft Live Labs Pivot collections

  - by John Conwell

  I've spent the past 3 weeks working a lot with Pivot from Microsoft Live Labs (http://getpivot.com/).  Pivot is a tool that allows you to visually explore data. Its an interesting take on visual data mining. Anyway, I've been writing a lot of code that creates a hierarchy of Pivot collections, where one item in the collection drills down into an entirly new collection. The dev community around Pivot is still very young, so there isnt much tribal knowledge built up yet.  I've spent a lot of time trying to get things to work through trial and error, as well as digging around in Reflector.  But I've finally got a framework built for programatically creating DeepZoom images, Pivot collections, Sparse Images, etc.   If anyone has any questions, or suggestions on a post topic, leave a comment and I'll try and answer your question.

• Adwords: Is there a drawback to setting a really high CPC to learn what works faster?

  - by Rob Sobers

  I'm toying with increasing my max CPC really high on all my keywords so ensure my ad gets shown in the top spot on page one in order to draw more clicks. I think this will be a good way to quickly figure out whether the ads I'm writing have a decent CTR and, more importantly, whether the landing pages I'm building are converting. Since I can set a max daily budget for my campaign, I won't risk breaking the bank. I can't think of any drawbacks, personally. Am I missing any?

• Trim on encrypted SSD--Urandom first?

  - by cb474

  My understanding (I'm not sure I'm getting this all right) is that if one uses Trim on an encrypted SSD, it defeats some of the security benefits, because the drive will write zeros to empty space (as files are deleted). See: http://www.askubuntu.com/questions/115823/trim-on-an-encrypted-ssd And: http://asalor.blogspot.com/2011/08/trim-dm-crypt-problems.html My question is: From the perspective of the performance of the SSD and the functioning of Trim, would it therefore be better to simply zero out the SSD, before setting up an encrypted system, rather than writing random data to the drive, with urandom, as one usually does? Would this basically leave one with the same level of security anyway? And more importantly, would it better enable the Trim functionality to work as intended, with the encrypted SSD?

• How to deal with tautology in comments?

  - by Tamás Szelei

  Sometimes I find myself in situations when the part of code that I am writing is (or seems to be) so self-evident that its name would be basically repeated as a comment: class Example { /// <summary> /// The location of the update. /// </summary> public Uri UpdateLocation { get; set; }; } (C# example, but please refer to the question as language-agnostic). A comment like that is useless; what am I doing wrong? Is it the choice of the name that is wrong? How could I comment parts like this better? Should I just skip the comment for things like this?

• Resources on learning to program in machine code?

  - by AceofSpades

  I'm a student, fresh into programming and loving it, from Java to C++ and down to C. I moved backwards to the barebones and thought to go further down to Assembly. But, to my surprise, a lot of people said it's not as fast as C and there is no use. They suggested learning either how to program a kernel or writing a C compiler. My dream is to learn to program in binary (machine code) or maybe program bare metal (program micro-controller physically) or write bios or boot loaders or something of that nature. The only possible thing I heard after so much research is that a hex editor is the closest thing to machine language I could find in this age and era. Are there other things I'm unaware of? Are there any resources to learn to program in machine code? Preferably on a 8-bit micro-controller/microprocessor. This question is similar to mine, but I'm interested in practical learning first and then understanding the theory.

• Extracting main article from webpage/feed. Is it legal/ethical?

  - by Mahdi Ghiasi

  There are some applications like Readability and Pocket, which are letting users to read the main content of web pages, in a clean interface or such. But the articles should be bookmarked from another application, or the web browser. However, I'm creating a news reader app (Zite and Flipboard are popular news reader apps), and I want to create a clean experience for users, so I want to show full content of articles inside my application. Some websites have fulltext feeds, and I'm using it. But about some other websites, which don't have full text feeds: I want to know, is it legal/ethical to use for example Readability API (Or maybe writing my own code for this) to show full text of articles inside my application?

• Mount an external drive at boot time only if it is plugged in.

  - by Jeremy

  I've got an entry for an external harddrive in my fstab: UUID="680C0FE30C0FAAE0" /jgdata ntfs noatime,rw But sometimes this drive isn't plugged in at boot time. This leaves me half way through a boot, with a prompt to "Continue Waiting, press S or press M" but no keypress has any affect at this stage (including ctrl-alt-delete, not even caps-lock). Short of writing a script to check the output of fdisk -l, how can I mount this drive at boot time only if it is present? It would be handy to have an fdisk entry for this drive, so I can just type mount /jgdata instead of needing a device name.

• Changing DisplayMode seems not to update Input&Graphic Dimension

  - by coding.mof

  I'm writing a small game using Slick and Nifty-GUI. At the program startup I set the DisplayMode using the following lines: AppGameContainer app = new ... app.setDisplayMode( 800, 600, false ); app.start(); I wrote a Nifty-ScreenController for my settings dialog in which the user can select the desired DisplayMode. When I try to set the new DisplayMode within this controller class the game window gets resized correctly but the Graphics and Input objects aren't updated accordingly. Therefore my rendering code just uses a part of the new window. I tried to set different DisplayModes in the main method to test if it's generally possible to invoke this method multiple times. It seems that changing the DisplayMode only works before I call app.start(). Furthermore I tried to update the Graphics & Input object manually but the init and setDimensions methods are package private. :( Does someone know what I'm doing wrong and how to change the DisplayMode correctly?

• Shadowmap first phase and shaders

  - by KaiserJohaan

  I am using OpenGL 3.3 and am tryin to implement shadow mapping using cube maps. I have a framebuffer with a depth attachment and a cube map texture. My question is how to design the shaders for the first pass, when creating the shadowmap. This is my vertex shader: in vec3 position; uniform mat4 lightWVP; void main() { gl_Position = lightWVP * vec4(position, 1.0); } Now, do I even need a fragment shader in this shader pass? from what I understand after reading http://www.opengl.org/wiki/Fragment_Shader, by default gl_FragCoord.z is written to the currently attached depth component (to which my cubemap texture is bound to). Thus I shouldnt even need a fragment shader for this pass and from what I understand, there is no other work to do in the fragment shader other than writing this value. Is this correct?

• The performance implications of IEnumerable vs. IQueryable

• What is the best wrapping strategy ?

  - by Riduidel

  Hi, I'm planning to integrate an external tool (ffmpeg in my particular case, but it could be anything, in fact, as lolng as its tasks are long running ones). This tool has a lot of command-line parameters. For now, I've done to simple things with it, already requiring me a good bunch of class writing, to embed all the information it can return to me. I now face the even more complex task of having to send it a bunch of parameters and to handle possible errors. So, what is a best way for that ? Create classes containing all possible options Relying upon a reverse equivalent of commons-cli / CliBuilder / OptionParser Directly write all options from user input Obiwan Kenobi powers (or anything I don't even know about) Please notice I do it in an uncommon language (for the sake of me, don't ask me what it is, as it looks like a desperate and sterile union between CoffeeScript and lua), as a consequence, there can be no framework doing what I want in the language I use.

• What ethical problems realistically arise in programming?

  - by Fishtoaster

  When I co-oped during college, I had to fill out an evaluation of the co-op afterwards. One metric I always had to rate was how much the company required me to "Make ethical decisions related to your profession." This always seemed kinda silly- I mean, my first co-op was writing java apps to manage industrial radios. There wasn't much moral ambiguity going on. Anyway, I'm wonder what sort of ethical dilemmas one might actually encounter in software development. Edit: It should be noted that no ethically-trained software engineer would ever consent to write a DestroyBaghdad procedure. Basic professional ethics would require him to write a DestroyCity procedure, to which Baghdad could be given as a parameter. - Nathanial Borenstein

• Looking for a very subtle unit testing example

  - by Stéphane Bruckert

  In the context of Continuous Integration, I need to teach unit testing to a 20-people audience of programmers. Everything will be all right, but I am still trying to find the perfect unit testing example. More than writing tests like a robot, I want to show that unit testing can help prevent very subtle errors. I am thinking of the following scenario to happen when doing a live TDD demo: the test cases would already be written, we would have to write methods together, most of us would naturally have forgotten to handle a specific case for a method, everyone would then be surprised, when seeing that all tests don't pass, the failing test would make us think more and realize that we forgot an important case. My question will probably finish as "too broad" or "not clear what you are asking", but we never know, one of you might have a great idea. Your answer can use Java and JUnit, though any other language will be fine since only the idea will matter.

• Where to find algorithms work?

  - by Misha

  The funnest parts of my projects have been the back-end algorithms work. I have worked on projects where I implemented Gaussian Mixture models, a Remez algorithm and a few Monte Carlo schemes. I loved figuring out how these processes worked and tuning them when they didn't. I recently graduated and my problem lies in the work I was able to find. The only jobs I have found, with my Electrical Engineering degree, are for writing user applications. Tasks such as fashioning web interfaces or front-ends for hardware devices. When I speak with potential employers about my interests they say they have no work of the sort. Where does one find work that involves implementing these kind of schemes?

• Building a six-screen setup. What video cards options are there?

  - by Stephan

  I'm building myself a nice setup with a massive amount of screen real estate. Since I had/have problems with video drivers in the past. I'm asking for advise here first. I want to connect at least six screens. What are the best options? What are the pitfalls? I preferably would not like to use closed binary blob drivers. usecase scenario: I'm writing a piece of software that has to interact with other systems. I would like to be able to see all of those systems, my code, lots of log files and documentation without the need to swap windows/screens. To just better see what im doing.

• How to recognize a good programmer?

  - by gius

  Our company is looking for new programmers. And here comes the problem - there are many developers who look really great at the interview, seem to know the technology you need and have a good job background, but after two moths of work, you find out that they are not able to work in a team, writing some code takes them very long time, and moreover, the result is not as good as it should be. So, do you use any formalized tests (are there any?)? How do you recognize a good programmer - and a good person? Are there any simple 'good' questions that might reveal the future problems? ...or is it just about your 'feeling' about the person (ie., mainly your experience), and trying him out? Edit: According to Manoj's answer, here is the question related to the coding task at the job interview.

• Proprietary AMD driver freezes my Ideapad

  - by mote

  I got this problem that I can't figure out what to do about. On Ideapad s205 with Ubuntu 12.04* (64), if I install Catalyst Centre 12.1 or newer it Freeze (lock's up), 1-3 times a day. It doesn't suffer freezing when using Radeon driver, but Radeon driver are considerably slower and flickers, so I would really prefer the proprietary driver (with no freezing). I reported the bug to launchpad but it doesn't get attention. -Also tried Ubuntu forums. Reported bug to AMD bug site "http://ati.cchtml.com/", but I don't think anybody reads it. Wrote AMD support several times, but get silly answers like "reinstall Windows". -Asked them to send the bug to Linux driver developers, but never heard a thing (more than once). The same nothing happens when writing to the feedback link from AMD driver download site. I'm so frustrated here, any advice would help. Thanks (*The same on Ubuntu 11.10)
