• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• How do I apply a computer science degree to web development?

  - by T. Webster

  I'm a web programmer, but I haven't found many opportunities to take advantage of a formal education in computer science. Maybe I'm not looking in the right places, but it seems to me like most of the web jobs I come across are CRUD, web forms, and data grids. For these jobs a formal CS background doesn't seem necessary, and you could do fine with O'Reilly cookbooks in jQuery, CSS 3, PHP, SQL, or ASP.NET MVC. What kinds of web developer jobs exist that really let you apply your computer science background? Do I need to branch out into other areas of programming to take full advantage of my degree?

• design for a parser to handle very large files

  - by user619818

  I have written a program which records protocol messages between an application and a hardware device which matches each application request with each hardware response. This is so that I can later remove the hardware, connect a 'replay' application to the main application and wait for an application request and reply with a matched copy of the requisite hardware reply message. My replay application saves the matched request/response in a list (using C++ std::list). This works fine on a small interaction session. My problem now is that I need to be able to use the replay over a long long session. With my current implementation, the replay program eventually uses up all available memory on my computer and crashes. So I need some sort of lookahead - and not parse the whole session in one go. Can anyone make any suggestions on how to get started?

• Shouldn't we count characters of code and comments instead of lines of code and comments? [closed]

  - by Gabriel

  Counting lines of code and comments is sometimes bogus, since most of what we write may be written in one or more lines, depending column count limitations, screen size, style and so forth. Since the commonly used languages (say C, C++, C# and Java) are free-form, wouldn't it be more clever to count characters instead? Edit: I'm not considering LOC-oriented programming where coders try to artificially match requirements by adding irrelevant comments or using multiple lines where less would be enough (or the opposite). I'm interested in better metrics that would be independent of coding style, to be used by honest programmers.

• Upgrading 8.10 server to LTS

  - by user3215

  I'm in a plan to upgrade ubuntu 8.10 vbox vm servers to LTS(obviously 10.04) as 8.10 has no support. As far as I know I'll be executing the following to upgrade: apt-get install update-manager-core do-release-upgrade anybody could tell me how could I upgrade a ubuntu server from alternate iso image(Is the alternate iso image used for desktop editons the same used for servers?)? I heard it's possible to upgrade an LTS directly to another LTS and how could I do this after upgrading 8.10 to 9.04 then directly to 10.04 skipping 9.10? 8.10 servers are hosting many services/applications/databases like apache2, tomcat6, ldap, mysql, cvs... and I'm not sure that all of them work as ever after the upgrade. If there is any precautions that I've to following before upgrading, please anyone let me know(ofcourse backup and I'm not going to take backup as I will be trying this on a copy of vdi/vmdk vms) Thanks!

• What are best practices for testing programs with stochastic behavior?

  - by John Doucette

  Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!

• CDN virtual subdomain causes duplicated content

  - by user3474818

  I have created a subdomain and a CNAME record which points to the domain root. The subdomain www.static.example.com is actually a copy of the entire website www.example.com and it is supposed to act as an CDN and serve static content in order to improve speed. However, all of my content can be accessed via subdomain aswell, so Google has indexed it all and now I am dealing with duplicated content. How could I deny access to crawlers for the subdomain baring in mind that I do not have different subfolder for subdomain, so I can't create a separate robots.txt file?

• Best keyboard to use with RollerMouse

  - by jrdioko

  I recently purchased a RollerMouse, which seems like an excellent way to eliminate pain caused by mousing. My question is: what good keyboard can other programmers recommend that would work well with it. I currently have a Microsoft ergonomic keyboard, but the curve and large wrist rest make it hard to use with the RollerMouse. By "good", I mean: Works with the RollerMouse (no wrist rest) Ergonomic (a slight curve or other features designed to be easy on your wrists/arms) Good for programming (that would be its primary use, no need for fancy media buttons or anything like that) Suggestions?

• How to program something with the expectation that it will work the first time?

  - by Peter Turner

  I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of hope or use a lot of premeditated debug strings). What's the best way to approach the Dijkstrain ideal for our programs? -or- Is this just some sort of pie-in-the-sky old fools quest for greatness applicable only to finite tasks that no one should hope for in our professional lives because programming is just too complex?

• Plan variable and call dependencies

  - by Gerenuk

  I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

• How do I pass tests with higher scores? [closed]

  - by user1867842

  How do I pass a test of programming knowledge for a higher score on oDesk.com? I have passed php and javascript tests but I have passed them with low scores and barley passing. This doesn't look too appealing for clients and I'm afraid that is the reason I am not being hired for a job. I know I am capable of doing web work and such. But I haven't been accepted for an interview or anything. Any idea how to study for something like this ?

• failing to boot after ''succesfully'' restoring from deja dup backup

  - by Jake

  Before upgrading to 12.04, I completely backed up 11.10 oneiric with deja-dup. In 12.04 I had major nvidia-related problems, so I decided to roll back to 11.10. I tried to restore from the backup and at first failed several times with "an uknown error occured". I reformated my hard drive, installed a fresh copy of 11.10 on the hard drive, and tried the restore again, with no success. I then booted from a live usb and ran the restore again after mounting the file system. I chose the restore location to be "file system" and the restore completed successfully, or so it said. After restarting my PC, all I got was a 'no operating system' error. I remounted my partition chrooted and installed the kernel. I am working now but my question concerns the restore. Why didn't the restore worked? I'm hoping someone has thought of something that I have not.

• Passing an objects rotation down through its children

  - by MintyAnt

  In my topdown 2d game you have a player with a sword, like an old Zelda game. The sword is a seperate entity, and its collision box "rotates" around the player like an orbit, but always follows the player wherever he goes. The player and sword both have a vector2 heading. The sword is a weapon object that is attached to the character. In order to allow swinging in a direction, I have the following property inside sword (RotateCopy returns a copy of the mHeading after rotation) public Vector2 Heading { get { return mHeading.RotateCopy(mOwner.Rotation); } } This seems a bit messy to me, and slower than it could be. Is there a better way to "translate" the base/owner component rotations through to whatever component I am using, like this sword? Would using a rotation MATRIX be better? (Curretnly rotates by sin/cos) If so, how can I "add" up the matrices? Thank you.

• What is the difference between Constant Vertex Attributes and Uniforms?

  - by Samaursa

  According to the OpenGL ES 2.0 Programming Guide: A constant vertex attribute is the same for all vertices of a primitive, and therefore only one value needs to be specified for all the vertices of a primitive. For uniforms the book states: ...any parameter to a shader that is constant across either all vertices or fragments (but that is not known at compile time) should be passed in as a uniform. I've always used uniforms for data that is constant for a primitive but now it appears that attributes can also be used in the same way. Is there more to constant vertex attribute than simply 'they are the same as uniforms'?

• Version 5.1.3 of ReSharper released

  - by TATWORTH

  Version 5.1.3 of Resharper has been released by Jetbrains. Download is at http://www.jetbrains.com/resharper/whatsnew/index.html The release notes are at http://blogs.jetbrains.com/dotnet/2011/02/resharper-513-is-released/ Whilst 5.1.3 addresses just a specific issue, if you are programming in C# or VB.NET and if you have never tried Resharper before, you should try it. When I first saw ReSharper in use, within a few minutes I knew that it was worthwhile buying my own copy. Since then I have used it at client site after client site and found it to be a very useful tool.

• What is the worst software bug in history? [closed]

  - by Amir Rezaei

  By having for example money and human suffering as the metric. What is the worst software bug in history? Note this is a specific question. Last month automaker Toyota announced a recall of 160,000 of its Prius hybrid vehicles following reports of vehicle warning lights illuminating for no reason, and cars' gasoline engines stalling unexpectedly. But unlike the large-scale auto recalls of years past, the root of the Prius issue wasn't a hardware problem -- it was a programming error in the smart car's embedded code. The Prius had a software bug.

• Techniques for Working Without a Debugger [closed]

  - by ashes999

  Possible Duplicate: How to effectively do manual debugging? Programming in a debugger is ideal. When I say a debugger, I mean something that will allow you to: Pause execution in the middle of some code (like a VM) Inspect variable values Optionally set variable values and call methods Unfortunately, we're not always blessed to work in environments that have debuggers. This can be for reasons such as: Debugger is too too too slow (Flash circa Flash 8) Interpreted language (Ruby, PHP) Scripting language (eg. inside RPG Maker XP) My question is, what is an effective way to debug without a debugger? The old method of "interleave code with print statements" is time-consuming and not sufficient.

• Is Ubuntu MAAS free? Will it remain like that?

  - by Bruno Pereira

  Ubuntu MAAS, very cool, awesome in fact, looks like a unique tool for several jobs. It looks free, but part of its documentation starts already with clauses that would scare anyone with interest in it: Documentation is copy righted by Canonical; Documentation must be used only for non-commercial purposes; If documentation is distributed within the non-commercial clause you must retain copyright; It just sounds a lot for a guide on how to install MAAS + Juju + Openstack and that scares me a bit. Under what license is Ubuntu MAAS distributed and what would be the reasoning for being so worried about copyrighting a guide like that so heavily? Is Ubuntu MAAS free? Will it continue like that?

• Alternative to Google Adsense which has good international coverage

  - by Yoga

  I have a technical blog (programming related) which has around 500 visit per days, 70% are international visitors and 30% are from US/CA. Google Adsense disabled my account due to invalid clicks so I can't use them (no need to explain here, they suck hard and never respect and listen to the publishers' appeal) I have tried adbrite and recently using chitika but they almost give me nothing, e.g. chitika 13,865 Page Views 4 clicks $0.01 The performance is so poor even I don't want to mention about it. I am already putting a full top banner and a 350x200 box in article body. I am researching if any alternative would provide more revenue for my internation visitors or technical visitors. Thanks.

• Port numbers appended to anchor tags

  - by glifchits

  I've built a static site. Locally, when I serve the content with python -m SimpleHTTPServer everything behaves normally, but when I copy the HTML onto the server and browse the site at the server's URL, some links will have a port number appended to the domain. For example: url.com:84/path where the correct path is url.com/path. The port number is usually different, always between 81-85. It is an Apache server. I'm not experienced with web server configuration, and I'm not the admin of the server. Let me know if there is more information that can help solve my problem. ~> cat /etc/*release* SuSE SLES-8 (i386) VERSION = 8.1 UnitedLinux 1.0 (i586) VERSION = 1.0 LSB_VERSION="1.2" DISTRIB_ID="UnitedLinux" DISTRIB_RELEASE="1.0" DISTRIB_DESCRIPTION="UnitedLinux 1.0 (i586)"

• How to restruct RAID 10?

  - by user276851

  We would like to alter the partition without losing data. Here is the sketch of the plan. I am wondering if it is doable using mdadm; and if so, please kindly point some reference on how to carry out the following steps. For RAID 10, there are four disks used. (1 2)(3 4) The idea is to work on 1 and 3 while keeping 2 and 4 as backup. 1: break RAID 10 into two arrays of RAID 0 => (1 3) (2 4) (how to?) 2: re-partition and format (1 3) 3: copy data from (2 4) to (1 3) 4: re-partition and format (2 4) exactly as (1 3) 5: join (2 4) with (1 3) to form RAID 10 (how to?) Does it sound doable? Thanks a lot! Add: It looks like this guy (drumfile) is doing something similar, but lack of enough detail.
