• New code base, what experiences/recommendations do you have?

  - by hlovdal

  I will later this year start on a project (embedded hardware, C, small company) where I believe that most (if not all) code will be new. So what experiences do you have to share as advice to starting a new code base? What have you been missing in projects that you have been working on? What has worked really well? What has not worked? Let's limit this question to be about things that relate directly to the code (e.g "banning the use of gets()": in scope, version control: border line, build system: out of scope).

• Translating error messages from an external API?

  - by Jan Fabry

  If I am localizing a piece of software that uses an external API, how should I handle error messages that originate in this API? I do not control the API, I only consume it. The error responses are not very structured: some contain error codes, some contain verbose details in the text, others almost nothing. Some errors can be fixed by the user (incorrect configuration), some are caused by the external service (server overload), some could be caused by a bug in my software (of course, this would be very unlikely...). I would like to provide a smooth experience to my end-users, so they know what went wrong and what they can do to fix it. What is the best strategy to use here? (This is a generalization of a question from the WordPress Stack Exchange. I thought it would be worth re-asking here, because it is not limited to WordPress plugins.)

• Why are so many DBCC commands undocumented?

  - by DBA

  Paul Randal of SQLskills.com does a great job of answering the question of why there are so many undocumented DBCC commands in his post Why are so many DBCC commands undocumented? I would like to go on to say that not only does this apply to the DBCC commands but is some respect to all parts of SQL, other Servers, IDE's, Operating Systems, just about everywhere. There is always something that just does not make it into the official documentation. And as Paul points out probably never will make it. That could be why there are so many "Tips & Tricks" types of books, blog post, etc. everywhere you look. And I also agree with Janos's comments on Paul's post, which was "I'm fine with them undocumented. All of us who need to use these commands know where to find "documentation" and whom to ask ". Till later,

• Does a programmer really need college?

  - by Dfranc3373

  I am currently a junior in college, however I have had multiple jobs programming since high school. Currently I work programming at a company part time using many different languages that I have learned the past few years. I recently sat down with a advisor and discovered with the classes I have left to take, I will learn next to nothing in them, as I already know the concepts and how to apply them for all the classes. My current job has offered me a full time position and I have had other companies email me as well. My question is if I know for a fact that I cannot learn more at college, is there even a point in staying? I know for a fact I could spend my time in more productive ways programming and working then what I am doing in school. Do you think to be looked at seriously as a programmer you need a degree?

• What is the benefit of triple buffering?

  - by user782220

  I read everything written in a previous question. From what I understand in double buffering the program must wait until the finished drawing is copied or swapped before starting the next drawing. In triple buffering the program has two back buffers and can immediately start drawing in the one that is not involved in such copying. But with triple buffering if you're in a situation where you can take advantage of the third buffer doesn't that suggest that you are drawing frames faster than the monitor can refresh. So then you don't actually get a higher frame rate. So what is the benefit of triple buffering then?

• Is true multithreading really necessary?

  - by Jonathan Graef

  So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

• Understanding the problem when things break in production

  - by bitcycle

  Scenario: You push to production The push broke multiple things That same build did not break qa or dev As a developer, you don't have prod access. There is lots of pressure from above to get things working agian. Specifics: PHP/MVC application that is API-driven in Zend. Deployed to a few servers. My question: While investigating, lets say I have a hunch that something is wrong. But, I don't know for sure. And, of course, I can't test things in production. If I have a suggested fix based on that hunch, would it be wise to try and apply it and see if it works, before understanding what the problem is?

• How to configure the default automount location?

  - by warkior

  I recently upgraded from Mint 12 to Ubuntu 12.10 + Cinnamon. I have an external usb drive that when I plug it in, automatically mounts to /media/[username]/Backup/. Thing is, under Mint, it didn't include the [username] portion. It just mounted to /media/Backup. My question is, how do I switch back to that format? I don't need the drive mounted under my username. Just under media. Thanks in advance.

• Who owns the intellectual property to Fragile Allegiance?

  - by analytik

  Fragile Allegiance was developed by Gremlin Interactive, which was later acquired by Infogrames (Atari). I couldn't find any details of the acquisition though. The only interesting thing I have found online is that the owner of the registered trademark Fragile Allegiance is Interplay, who published Fragile Allegiance. However, the only copyright note I've found was in one installation .ini file, claiming it for Gremlin. What are the common business practices when it comes to old, unused IPs? What do publishers/developers actually need to legally claim an intellectual property? Does anyone have an experience with contacting big publishers with copyright/IP inquiries? Related legal question.

• Why are part-time jobs in programming an anomality?

  - by Mikle

  I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

• Literature in programming and computer science

  - by Peter Turner

  I hope, gentle programmers, that you'll forgive me for not asking a "Soft Question" on theoreticalCS.SE and asking this here. It has recently come to my attention that bigendian came from Jonathan Swift's Gulliver's Travels. I was pretty surprised when listening to the book on my commute to hear something I'd only heard before in Comp Sci / Engineering classes. I thought it was some sort of nouveau-politically incorrect piece of holdover jargon like Master and Slave drives or Polish Notation. Are there any other incidents, not of politically incorrect jargon, but of literature influencing aspects of computers, programming or software development?

• How to retrieve old facebook/XMPP messages as well as new with kopete?

  - by searchfgold6789

  I have been considering using Kopete to use Facebook chat instead of logging on to Facebook with a web browser. That way, I can integrate messages with my KDE desktop better. The problem is, when I open Kopete, I am unable to see messages that I recieved in Facebook while Kopete was not opened. I can only see messages that I sent or received when Kopete was open. The same thing happens in Outlook.com (which is a website that connects to Facebook), Pidgin software, and other instant messaging tools. So my question is, how can I receive these messages with a desktop chat application in KDE, such as Kopete? Facebook has made their API publicly available to developers, and KDE has its own Facebook integration plugin. So it would seem achievable.

• How did programmers resolve their problems before the internet?

  - by 9a3eedi

  When programming, anytime I get stuck, perhaps with a compiler error that doesn't make sense, or from a GUI function that didn't do what I expected, I automatically google my problem, find someone else that faced the same thing, and read what's going on and why I'm getting the problem. Before the internet, how did people handle these situations? People used to read books and manuals more, I know. But books don't explain everything, like the odd compiler problem that you get sometimes, or nothing showing up on your screen despite you clearly writing correct OpenGL code. How did people cope when facing challenges? Did they simply "bash their head" on the wall till they figured it out? Is there something people used to do regularly on the side that gave them the ability to get themselves unstuck more easily? Were libraries/compilers much simpler back then? I've been asking this question because I sometimes feel guilty depending on Google so much when I'm pretty sure programmers before my time were more independent when it comes to facing these matters.

• Reuse the data CRUD methods in data access layer, but they are updated too quickly

  - by ValidfroM

  I agree that we should put CRUD methods in a data access layer, However, in my current project I have some issues. It is a legacy system, and there are quite a lot CRUD methods in some concrete manager classes. People including me seem to just add new methods to it, rather than reuse the existing methods. Because We don't know whether the existing method is what we need Even if we have source code, do we really need read other's code then make decision? It is updated too quickly. Do not have time get familiar with the DAO API. Back to the question, how do you solve that in your project? If we say "reuse", it really needs to be reusable rather than just an excuse.

• How to deal with author rights when building a website

  - by user393381

  I was thinking about developing a website that would involved photos and was wondering how to deal with the legal/author rights aspects. If someone could direct me to some resources to find out, I would appreciate. If I take Flicker as an example, people can upload pictures and share them. What if someone a picture that belong to someone else, like a professional photographer? Or what if someone upload a picture of someone and that person does not agree to that? Same question if someone put a picture in there that is not acceptable? Can a Disclaimer or Terms of Use avoid the Website (or the person managing a Website) to get in trouble when someone violate the law? Thanks.

• Remapping Shift Selection in Gnome Terminal

  - by Gowie47

  Hey so I was hoping somebody could help me out in finding a way to get shift-selection working in gnome-terminal on Ubuntu 11.10. I found the question/bug report below but neither seem to have a solution. I use Emacs for development and being able to select my current line with shift-ctrl-a/e is something I find myself trying to do every couple of minutes. I use 10.04 at work and this is possible so I am not sure what has changed. If it matters I am using Gnome 3 Shell and I use bashish to style my terminal. Thanks in advance! https://bugs.launchpad.net/ubuntu/+source/vte/+bug/546021 http://askubuntu.com/questions/31991/using-the-shift-key-in-terminal

• Combining Multiple Queries and Parameters into One Operation

  - by shay.shmeltzer

  This question came up twice this week and while the solution is explained in a couple of previous blog entries I did, I thought that showing off the complete solution in a single video would be nice. The scenario is that you have two VOs with queries that are based on a parameter, I showed in the past how to create a parameter form that executes the query - and you can do this for both. But what if you actually need just one value to drive both queries? How do you combine two parameter forms and two buttons into one? This is what this video shows you. The steps are: Creating two parameter forms Setting the value of a parameter in the binding tab Creating a backing bean to execute the code for one button Adding the code to execute another operation Remarking the parts that can be dropped from the screen Check it out here:

• Including slick2d or slick-util in maven build?

  - by BotskoNet

  I'm converting a project to lwjgl and trying to use slick-util as well. There's no slick-util maven repo anywhere (nor slick2d itself anymore). I've included local dependancies before using <dependency> <groupId>org.newdawn</groupId> <artifactId>slick</artifactId> <version>237</version> <scope>system</scope> <systemPath>${project.basedir}/lib/slick-util.jar</systemPath> </dependency> The maven package process runs without issue, but when I try to run the jar, it errors out with a ClassNotFoundException. There's no mention of slick-util in the manifest and I can't find out how to make my game load that jar properly. Side question: how do I ensure when I distribute my applications, the game properly installs these libraries?

• Innovation on CS

  - by guiman

  Hi all, its been some time that i've been thinking about creating something that could help the web community and leave some mark, but the problem that there are no ideas poping out of my head. So 2 questions comes to my mind: First, how did projects like Twitter, Google or any other big project that had changed our way of living in the internet get started? Secondly, do we have to force it or just keep doing what we do best and wait to that idea that could change things? While writting this question, one quote come to mind: Imagination is more important than knowledge Albert Einstein

• Was it necessary to build this site in ASP.NET ?

  - by Andrew M

  From what I'm told, the whole StackOverflow/StackExchange 'stack' is based on Microsoft's ASP.NET. SO and the SE sites are probably the most complex that I visit on a regular basis. There's a lot going on in every page - lots of different boxes, pulling data from different places and changing dynamically and responding to user interaction. And the sites work very smoothly, despite the high traffic. My question is, could this have been achieved using a different platform/framework? Does ASP.NET lend itself to more complex projects where other web frameworks would strain and falter? Or is the choice pretty incidental?

• How to measure the right time to bring a new client?

  - by Byron Sommardahl

  My growing company has a team of developers working on a number of separate projects. Our developers depend on us to keep them working, and we depend on them to make our clients happy. Our projects have differing start and end dates, as you can imagine. The company's responsibility to the developers is to make sure we have clients waiting in the wings so that when one project ends, another can start. For now, finding clients is not a problem and not the topic of this question. What I'm trying to think through right now is, how can I best measure/view/evaluate the end dates of projects so that I know when I need to start courting the next client. Is there a tool that does this? If it's just a spreadsheet, what might it look like?

• Java Plugin - Firefox

  - by Tomassino

  Having trouble getting Java to work with Firefox (22), I have followed the advice in this question and on the official Java site, but nothing seems to work. I have the latest Java (1.7.0_25) in /opt/java and have set a symlink in /usr/libs/mozilla/plugins for the libnpjp2.so file. I can see the file in the terminal and Java runs fine. However Firefox shows nothing in about:plugins. I have also run export JAVA_HOME="/opt/java/jre1.7.0_05/bin/java" to be on the safe side. I know there are multiple plugin directories such as /usr/lib/firefox/plugins and /usr/lib/firefox-addons/plugins, but all my current plugins show they are located in /usr/lib/mozilla/plugins when viewing the about:plugins page. A bit stuck on where to go next?
