• in ubuntu 12.04 how may i know if my devices have it's driver installed??

  - by Aldo

  i have a dell N4110 laptop, and i want to know if the driver is installed and working well, something like the device manager in windows , or another way to know if a device is driverless or if the device might have a better driver, like my mousepad, in windows it have multi-touch gestures , that scrolls or zoom with two fingers (like an ipod) but in ubuntu it just works the right part as a scroll bar, so maybe it is installed one driver, but i need other one that uses well my devices. and the grphics card, i have not idea if it is well installed or isn't. i have a Intel 3000hd graphics card. thank you for your time. have a nice day people! =D

• Should I be using a game engine?

  - by Kyle

  I'm an experienced programmer, but I'm completely new to making games. I'm thinking of making an iPhone game that is similar to a 2d tower defense type game. In the web programming world, it would be a big waste of time to make a website without using some sort of web framework (eg ruby on rails). Is that the same for making games? Do people mostly use some sort of framework/game engine for making a game? If so, what are the popular ones for iOS?

• Why do exclusively outsourcing projects as a company?

  - by user19833

  A prospective employer told me they took a company level decision to only do outsourcing projects. I do not understand why did they take such a decision and the guy I talked to did not elaborate. He further said only that "their intention is to build software components". Since they are growing quite fast and reached around 300 employees, shouldn't they be at least open to the possibility of having a project of their own, maybe? All other companies I've had contact with were at least open to have one in the future.. I talked to a few of their employees and some are working in parallel on more than 2 outsourced projects (dividing time something like 4 + 4 hours / day). It seemed like a lot of projects with a period of a few months, maybe half an year come and go... Why would a company choose to provide only outsourcing services like that? How does it work to keep hundreds of people on outsourced projects with a seemingly high project turnover rate?

• Is it worth becoming a programmer?

  - by D. Higueras

  Hi everybody. I'm a first year student in CS and I absolutely love programming. Many people have told me it isn't so good once you start working. Some things like bringing your work home(thinking about how to solve problems), working many hours when the timeline reaches an end an so on. I've heard being a system administrator is a lot less stressing job, since you don't have to worry about it at home. So my questions are(for experienced programmers): Is it worth becoming a programmer? Does your job satisfy you enough to overcome these problems? Thanks in advance.

• Microsoft Office 2010 General Availability

  So, I was at TechEd 2010 talking a lot about Office 2010 solutions development last week and love was in the airmostly because I gave out hundreds of t-shirts with our www.iheartmacros.com URL on them. I would say to people coming to our kiosk, This shirt loves you and hand them a shirt. But, I digress. I did an interview for Channel 9 thats getting lots of view. In it I discuss whats new for solution building with Office 2010 and SharePoint 2010. I really like the way this video was produced. Check...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• What made you contribute to that open source project? [closed]

  - by Ermin

  I'm interested in real experience and personal answers not just those standard worn out "benefits of contributing to open source" that we all memorized by heart by now. I've met many people who contribute to open source project and almost never did this topic come up: why did they contribute to this open source project. So, if you've contributed to an open source project before in any way, can you please pause for a second and try to remember what really made you decide to contribute to that particular project. Was it a random decision, was it because you were bored, was it because the company you worked for was already using it and you contributed as part of your job, was it because the project was too big you wanted to get contracts, or the project was too small you wanted to build it, or because your prof or co-worker asked you to help with his open source project, or..... To substantiate your reasons, please mention the project name and rate your involvement (heavy, occasional, light, once).

• TechEd 2014 Day 2

  - by John Paul Cook

  Today people asked me about backing up older versions of SQL Server to Azure. Older versions back to SQL Server 2005 can be easily backed up to Azure Storage by installing Microsoft SQL Server Backup to Windows Azure Tool. It installs a service of the same name that applies rules to SQL Server backups. You can tell the tool to backup or encrypt your SQL Server backups. You can have it automatically upload your backups to Azure Storage. Even if you don’t want to upload your backups to Azure, you might...(read more)

• "// ..." comments at end of code block after } - good or bad?

  - by gablin

  I've often seen such comments be used: function foo() { ... } // foo while (...) { ... } // while if (...) { ... } // if and sometimes even as far as if (condition) { ... } // if (condition) I've never understood this practice and thus never applied it. If your code is so long that you need to know what this ending } is then perhaps you should consider splitting it up into separate functions. Also, most developers tools are able to jump to the matching bracket. And finally the last is, for me, a clear violation to the DRY principle; if you change the condition you would have to remember to change the comment as well (or else it could get messy for the maintainer, or even for you). So why do people use this? Should we use it, or is it bad practice?

• Tracking 502 bad gateway error

  - by dasickle

  I moved my Wordpress site to WP Engine and now I constantly get 502 errors. I spoke with support and they said that its because I have a lot of DB queries. I ran some tests and my frontpage only has 95 queries and page size is about 500kb. Most inner pages are around 60 queries. All queries are very short. Some people tell me its common with WP Engine because they run nginx. Why do I keep getting these errors and is there a way to track how many of them happen on daily basis? P.S. WP Engine log is empty so cant see the 502's there.

• DIY Wirelessly Charged LED Lanterns

  - by Jason Fitzpatrick

  Earlier this year we shared a clever project that turned LEDs, batteries, and PVC into mini, waterproof, and virtually indestructible lanterns. This remake of the project makes the units rechargeable. Our favorite part about this project–the upgrade to an older project and the introduction of wireless charging aside–is the fact that the maker behind it is 15 years old. It’s great to see younger people taking an interest in tinkering!

• How to enable a symlink in this case

  - by Bragboy

  I cannot categorize this question under ubuntu since it has nothing to do with it. But I know people here can definitely answer this. I login to one of my deployment boxes using SSH (no ubuntu here). I am working in a tool called TeamCity which uses a folder called ".BuildServer" under home directory of the user. This folder may grow in size as the application runs but the current user is only given a limited amount of space. But the good thing this I got a folder access outside /home/deploy (deploy being the user here) folder. I now want to link this .BuildServer inside the /home/deploy directory to the other folder where I got permission for (meaning all the files should be re-routed to that directory) Hope my question was clear, please help.

• How to interview for a developer position [closed]

  - by Brandon Moore

  I know this question may not seem to fit the format of this site perfectly, but I think it's definitely the right place to ask it from the perspective of getting the information I'm looking for (and I'm sure many others are wanting to know). I would like to hear from some people who feel they've become adept at interviewing developers. What's the secret to making sure you hire someone whose work actually looks as good as their resume? Please try to keep your answers concise. I understand this question has multiple answers and that's why it doesn't fit the format of this site well. So at least refrain from offering your opinions. Just offer any advice you've actually tried and have found to work well for you. And no linking to other resources. Only looking for personal experience.

• Performance impact of the new mtmalloc memory allocator

  - by nospam(at)example.com (Joerg Moellenkamp)

  I wrote at a number of occasions (here or here), that it could be really beneficial to use a different memory allocator for highly-threaded workloads, as the standard allocator is well ... the standard, however not very effective as soon as many threads comes into play. I didn't wrote about this as it was in my phase of silence but there was some change in the allocator area, Solaris 10 got a revamped mtmalloc allocator in version Solaris 10 08/11 (as described in "libmtmalloc Improvements"). The new memory allocator was introduced to Solaris development by the PSARC case 2010/212. But what's the effect of this new allocator and how does it works? Rickey C. Weisner wrote a nice article with "How Memory Allocation Affects Performance in Multithreaded Programs" explaining the inner mechanism of various allocators but he also publishes test results comparing Hoard, mtmalloc, umem, new mtmalloc and the libc malloc. Really interesting read and a must for people running applications on servers with a high number of threads.

• How can I keep track of a battle log on a web game?

  - by Jay W

  Recently I started working on a Web turn-based PvP RPG game. Now I'm working on the battle system but I encountered some issues: How can I keep track of everything that happens in the battle? It should keep track of the characters on the field, inventory, the damage done etc. I first thought I would simply put it in the (MySQL) database, but I think it will be too much. Especially if several people are in a battle. I thought of puting this in sessions or cookies but I don't think thats reliable. Does anyone have an idea how I can do this?

• Free serif font with clearly distinguishable 0 (zero) character

  - by l0b0

  I'm using gLabels to create some small pieces of paper to give away to people - Just two lines of about 15-20 characters each. One of the important parts of the design is that there are no "o" ("oh") characters, but there are "0" ("zero") characters in an all-lowercase URL. Therefore I need a non-monospaced (and very legible in print) font where "0" cannot be confused with "o" even without reference. The closest thing I've found so far is Andale Mono and Inconsolata , but they are both monospace, and as such not very easy to read in print. Alternatively, to find a font myself, is there some way to preview all fonts in the Ubuntu repositories without installing them?

• proper model for a multi site rails app

  - by JeffTaggarty

  Hi Guys, I am not sure if this is correct place to ask this question. My apologies if it is not. I need to create a web app where people will sign up, call it main-app.com, when they sign up my code will generate a usersite.my-app.com, they will login and only be able to manage their mini site. My question is, is it correct to model this out by creating a table for site, a table for user, users belong to site and site has many users. Then I should create a content table that belongs to user AND site? is that right? Thanks Jeff

• No such file but the file is there!

  - by user288757

  I'm trying to compile a C++ file with some includes. My main file (well I didn't make it hdf5_getters includes a file which includes the file hdf5.h, also not my design but it's a downloaded library. Every time I try to compile it I get the error message that the file hdf5.h does not exist while it clearly does. I started reading on the internet and people say it can happen because it's a 32bit binary running on a 64bit architecture. But I'm running a 32bit Ubuntu so that can't be it... I'm out of ideas, if anyone can help me please :) This is the errormessage with commands: make hdf5_getters g++ -c -Wall -std=c++0x -O2 -c hdf5_getters.cc In file included from H5Cpp.h:20:0, from hdf5_getters.cc:34: H5Include.h:17:18: fatal error: hdf5.h: No such file or directory #include <hdf5.h> ^ compilation terminated. make: *** [hdf5_getters.o] Error 1

• Preparing to release code as open-source

  - by Raphael

  I have developed a fully functional tool which I would like not only to share with anyone interested but also get support from the community. This tool is cross-platform, written in C++ with Qt, the code is well commented but I still lack any documentation. There are also some small issues and improvements to be made before I can call it a stable, final version. What are the first steps that I have to take to release code as open-source and attracting people interested in contributing? This is my first serious attempt to release open-source code and I really don't know where to start. Should I just push it to Github put together a small wiki and pray for the best?

• Are there any reasons to use Bazaar over Hg or Git?

  - by NeuronQ

  The world of DVCSs seems split between Git and Mercurial nowadays, but lots of projects and places (like my new employer) use Bazaar. And it's not a thing of inertia where people just use something because "that's how it's always been done", these guys are agile and sometimes seem to embrace change just for the fun of having more things to fix. Yet no one gave me any convincing arguments for using Bzr over Hg or Git. I can get seeing Git as "too complicated" but you can't use this king of judgement between Hg and Bzr. So then, what are the features of Bazaar that would justify its use over Mercurial (or Git) in any given situation?

• Ubuntu 11.04 seem's like a laggy OS

  - by user772401

  I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..
