• Good text editor for Ruby on Rails programming?

  - by Andrew

  I'm trying to find a text editor that I can use for doing Ruby on Rails development. I have been using TextMate on my Mac and would love to find something that even comes close to that experience. My Ubuntu laptop is a little old, and doesn't have a lot of memory, so I need something lightweight. I don't need/want a bloated IDE because the performance on my slow laptop would be terrible. It would be nice if this text editor had: Syntax highlighting A project/file browser view to be able to open files in my project Keyboard shortcuts (don't need them as much)

• What is Cyber Monday? [Infographic]

  - by Jason Fitzpatrick

  Nearly everyone is familiar with Black Friday, the massive shopping day right after Thanksgiving, but Cyber Monday is a recent invention. Check out this infographic for the low down. Cyber Monday is only a scant six years old, an invention of online retailers looking to create a shopping day to compete with the in-store frenzy of Black Friday. Although quite a few retailers offer online Black Friday deals, Cyber Monday is a the biggest day for online deals–many shoppers fail to find the things they were looking for on Black Friday and turn to online sources.

• Moving camera, or camera with discrete "screens"?

  - by Jacob Millward

  I'm making a game with a friend, but having trouble deciding on a camera style. The basic idea for the game, is having a randomly generated 2-dimensional world, with settlements in it. These settlements would have access to different resources, and it would be the job of the player to create bridges and ladders and links between these villages so they can trade. The player would advance personally by getting better gear, fighting monsters and looking for materials in the world, in order to craft and trade them at the settlements. My friend wants to use an old-style camera, where the world is split into a discrete number of screens that the player moves between. Similar to early Zelda dungeons, or Knytt Stories. This is opposite to me, as I want a standard camera that follows the player around as I feel the split-screen style camera limits the game. Can anyone argue the case either way? We've hit a massive roadblock here and can't seem to get past it.

• HTG Explains: Photography with Film-Based Cameras

  - by Eric Z Goodnight

  We’ve become reliant on digital cameras since they are so easy to use. But have you ever wondered how film-based photography works? Read on to increase your photographic knowledge—or to develop an new appreciation for your point and click camera. Film-based cameras, to some, are a relic of the past. Simply an old technology made obsolete by the new and improved. But to many, film is an artisan’s material, and a photographic experience no digital system could hope to ever recreate. While many photographers, professional and amateur will swear by the quality of both film-based or digital cameras—the fact remains that film is still a valid way to take great photographs, and a fascinating way to learn more about how photography works.  HTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)What is a Histogram, and How Can I Use it to Improve My Photos?

• Why can't GoogleBot forget a 404 File Does Not Exist?

  - by Sam

  Hi folks, For two months now, googlebot is trying to get a file which does not exist anymore. This is just one example out of many: I had renamed the file to a better name and removed the old file. Now, why does Google insist on getting a file which it already has seen does not exist for months? doesn't it just give up and get on being a happy bot? My Error log file is filled with these repeating lines all wanting to get that one file, although they know for already long time that its not there: What to do in these situations? Are there automatic redirection rules that handle via 301 to the home page?

• I dont know my password and wont let me change it via GRUB

  - by josh

  I recently turned off the login password so i would not have to enter my password every time I turn the system on. But now when I try to update or download anything it asks me for my password so I enter my old password and it keeps telling me its wrong when I have only ever had the 1 password and its a simple 1 so I would not forget and considering I have only had UBUNTU installed for two days it is really frustrating. I have also tried resetting it via the GRUB but it wont let me type the new password. Please help ASAP.

• Software developer needs Validation for VA Chap 31 to purchase Macbook Pro vs. PC [closed]

  - by David

  I am currently attending college with a path of software development and working towards my BS thanks to VA Chap 31. My old original Macbook Pro is near dead and no longer upgradable on the software or hardware side. The VA has offered to purchase a PC laptop for me (Because my syllabi says computer required), but I do not want to go backwards. I have a lot invested in OS X software and Mac peripherals, not to mention I prefer to program in an Apple environment. PC vs. Mac costs are so drastically different that I must validate my request for a new Macbook Pro. In my request to the VA, I stated the above and some other topics but they requested more validation. Can anyone recommend issues, reasons, etc. to help me validate this purchase by the VA for school? Thanks in advance for your help, David

• Recommended method towards making custom maps for a 2d game?

  - by Qasim

  I am planning on making a 2D game, however different from my last personal projects I want this one to have enhanced graphics, with custom-designed levels. My previous 2d platformers were tile-based, in which I made a map editor for to create levels. However, I am wondering the best way to implement custom designed maps? For say, some grass is a litter higher than others, flowers here and there, cool drawings and structures along the way, etc. instead of just the same old tiles over and over again. I am thinking but I just can't grasp the idea of how to implement it. I have seen it done in other games and am interested to see how they accomplish it, but can't get my hands on some source code. :(

• Which tools you use to make gtk themes?

  - by tutuca

  I'm trying to make a new gtk theme using the murrine engine, using Humanity (default in ubuntu 9.10) as a template. You can grab the code in http://github.com/tutuca/themes However, I found cumbersome the process of creating a new theme with it. There is no central starting point. The documentation of both, the engine options (gtkrc's and stuff), and general theming practices (the format of the index.theme files, folders, bla bla) is scarce, How to's and tutorials are often old or subject to lots of opinionated debate and results confusing (to me, having a web developer background, at least :-). So... I wanted to ask to the fellows gtk themers and artist out there: Which tools you use to create a new theme, and how does your average workflow looks like?

• Way in over my head! (Dealing with better programmers)

  - by darkman

  I've just been hired to be part of a group that is developing in C++. Before, I've been coding on and off at my job for the past 11 years (some C, some Fortran, some C++). The coding I've done was mostly maintaining and adding new features to one of our systems. The code, being 10 years old, did not contain all the modern C++ stuff. Lo and behold, my new job is filled with programmers with 5-10 years experience of pure coding and they all use the most modern aspects of C++ (C++11, template, lambda, etc, etc). They are expecting someone with that same experience... Well, I've been working for 15 years total but when I looked at their code, I couldn't understand half of it! :-| Anyone been in that situation? What would you recommend?

• Gotcha | Installing .net 4.0 and IIS 6

  - by Steve Clements

  Just a quick one, seems pretty weird to me. I installed .net 4.0 on an old IIS6 box, ready to deploy a asp.net mvc app targeting .net 4.0.  I thought, which to me seems logical, that I install .net 4.0, setup a new web site, new app pool, set the web site to asp.net 4.0 (other configuration also needed to run MVC on IIS6 here and here) and it would just work. Errr… No.  The page cannot be displayed!  Nothing to do with MVC. Apparently just because you have installed .net 4 and the option is available in IIS, it’s not enabled.  I’m not going to repeat anything here…take a look at this post – clear, easy steps on exactly what you need to do and how to check if this is the problem. http://johan.driessen.se/archive/2010/04/13/getting-an-asp.net-4-application-to-work-on-iis6.aspx

• Evolution in coding standards, how do you deal with them?

  - by WardB

  How do you deal with evolution in the coding standards / style guide in a project for the existing code base? Let's say someone on your team discovered a better way of object instantiation in the programming language. It's not that the old way is bad or buggy, it's just that the new way is less verbose and feels much more elegant. And all team members really like it. Would you change all exisiting code? Let's say your codebase is about 500.000+ lines of code. Would you still want to change all existing code? Or would you only let new code adhere to the new standard? Basically lose consistency? How do you deal with an evolution in the coding standards on your project?

• Trouble after Ubuntu 12.10 upgrade

  - by highsciguy

  Over night I tried to upgrade to (k)ubuntu 12.10. Unfortunately kdm (neither lightdm) doesn't show up after boot. I found several posts describing errors due to the migration from kdm to lightdm. Some sugest reinstallation of kdm. Therefore I logged into a shell and tried to install it using apt-get. However it turned out that network is not available. ifconfig showes that only the loopback device lo is available. What can I do to get lan or wlan network working on the commandline? I relized that grub still runs the old tuxonice kernel which I installed from ppa. Is it possible that the installation didn't finish and left me in an inkonsistent state in which the kernel version does not match the modules? How can I proceed the installation from the downloaded packages?

• "bad mirror archive" : What should I put as the "mirror of ubuntu archive" on installation of ubuntu?

  - by rockit

  I'm trying to set up ubuntu from my old macintosh laptop, but when it asks me to put in the "mirror of ubuntu archive" I run into problems. For the mirror, I put in mirror.anl.gov for the ubuntu archive mirror directory, i put in pub/ubuntu/ Then I leave the http proxy blank and hit "continue" It then tries to "download release files", which starts at 0%, and eventually jumps straight to 100% and then it presents me with an error of "bad mirror archive". Any advice? I never set up ubuntu before, and I'm really struggling with this step.

• ASP.Net Development Tips

  Opening ASP.NET 3.5 websites in VWD 2010 VWD Express 2010 by default supports ASP.NET 4.0. If you are opening old projects that are based on either ASP.NET 3.5 or ASP.NET 2.0, you need to make some adjustments. Refer to the steps below: 1. Back up the folder containing your ASP.NET 3.5 website files and place it in another directory. For example, suppose this is the path of your original ASP.NET website that needs to be opened in VWD 2010: L:aspdotnetprojectsareaofcirclefunction Copy that folder (do not cut it) and put it in a separate folder that can be accessed by VWD 2010.

• Updating Pages after migration of website

  - by DLackey

  My web site was coded in Coldfusion and over the years has obtained a good ranking. I recently migrated the front-end to a Wordpress site and wanted to know what is ideal way of updating Google and the various search engines of of the updates. For example, the home page of index.cfm is no longer valid since it's index.php. I've submitted an updated sitemap.xml file to Google. I'm sure my site will slip some while the search engines re-index my site but I'd like to try and minimize this as much as possible with the holidays coming up (my site is a service oriented site that caters to people who travel during the holidays). Right now, the old .cfm pages are still online but are re-routed to the appropriate Wordpress page (for example, about.cfm is now routed to /about/ using a cflocation tag.). Not sure if I should pull down the .cfm pages all together or leave them in place until the new pages are picked up by the search engines. Any advice would be helpful.

• How To Specify Bitrate, Codec and Demultiplexing for VLC Video Capture or Recording

  - by Subhash

  I capture video from old TV tuner card - Pinnacle PCTV - using VLC. The video is from the Composite input and audio is from I guess the mixer or Line in. The command I use is: vlc v4l2:///dev/video0:normal=pal:width=720:height=576:input=1 :input-slave="alsa://hw:0,0" In VLC, I have enabled the Advanced Controls toolbar, which allows me to record videos when I want to. However, these videos are uncompressed - very big and play only with VLC. Totem throws the "Could not demultiplex stream" error. I need to convert them using WinFF to reduce their size and make them playable with Totem and other software. My question is whether I can configure the recording settings - the codecs and the bitrate, and also get the stream demultiplexed. If I pass any -sout parameter with command I get a "Segmentation fault". I use 64-bit Ubuntu 10.10.

• How could there still not be a mysqldb module for Python 3?

  - by itsadok

  This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

• Do you start migrating your Swing project to JavaFX

  - by Yan Cheng CHEOK

  I have a 4 years old project which is written in Swing + SwingX. Currently, it is still alive and still kicking. However, as more GUI related feature requests coming in (For instance, a sortable tree table), I start to feel the difficulty in fulling the requests. This is true especially there isn't active development going around SwingX project. Also, I hardly can find any good, yet being actively maintained/ developed/ evolving GUI Java framework. I was wondering, any of Swing developers feel the same thing? Have you start to migrate your Swing project to a much more active developed GUI framework like JavaFX?

• Hack a Nintendo Zapper into a Real Life Laser Blaster

Courtesy of the tinkers over at North Street Labs, we’re treated to a Nintendo zapper overhaul that replaces the guts with a powerful 2W blue laser, a battery pack, and a keyed safety switch.
