• font showing up as squares during installation

  - by EmileBeaulieu

  I am very new to linux, just so you know. I chose ubuntu as my first linux distro. I created a boot flash drive and installed it on to my little netbook. It works fine, and I'm having fun playing around with it. Now I wanted to install it on my main computer, however after inserting the flash drive and rebooting, and after the initial startup screen, the first screen that comes up has ALL the text showing up as little squares! If I remember correctly from when I installed it on the netbook, it's asking me what language I want on this screen. Why would this happen on my main computer and not on the little netbook, when I used the exact same flash drive and installation? I have a screenshot, but since I'm new here, it won't let me post it.

• Drawing a textured triangle with CPU instead of GPU

  - by Jenko

  I understand the benefits of GPU rendering and such, but for a certain limited application I need to render textured triangles purely using CPU. I've built a 3D engine capable of object handling, transform, projection, culling and the likes ... now all I need is a little code snippet that draws a single textured triangle onto a bitmap... any language accepted! Inputs: Texture bitmap, Triangle U/V/W coords, Triangle X/Y screen coords Output: The textured triangle drawn at the given screen coords I've currently been using a platform function to draw triangles to screen, but I'm looking to handle it myself to speeden up the process.

• Pressing p in dash results in weird B

  - by ayckoster

  Today I tried to open Skype in my dash and discovered that my "p" key does not work properly. Instead of p I get B. In every other application the key works properly. When I copy the text "skyBe" from dash into another application it sais "skype". I tried every other character and they seem fine, it's only the "p" key. I think that the problem is dash. Anyone else has the same problem? Here is an image. I enter "skype" and get this: What causes this problem and how can I fix it? Environment: Lenovo W500 with German keyboard Ubuntu 12.10 Language settings: English Keyboard layout: German

• Worthwhile to upgrade my Ruby Pickaxe book?

  - by ewindisch

  I have Programming Ruby, The Pragmatic Programmers' Guide, Second Edition which covers Ruby 1.8. It has been several years since I have programmed in Ruby, but I'd like to refresh my memory and bring my knowledge current. With most programming languages, I've found that I can skip books that only concern a single version bump. Yet, Ruby is a young language and I understand there may have been significant changes in 1.9. Although I already have the second edition, is it worthwhile to buy the third edition for Ruby 1.9? Are the differences that vast, or will it be simple enough to catch up to 1.9 with the online docs?

• Executing Shell Commands - PHP or Python?

  - by chadpeppers

  I know basically two languages: Python and PHP. I am primarily a Drupal developer. I have a great idea in creating a command line program that will help some of the mundane tasks and bring my efficiency up quite a bit. The concept is that of a complete console program, almost like the days when I learned C++ using stdin/out. I want to use this came concept but for this program. I am going to be executing shell commands (mainly drush commands, if you are familiar with drush its drupals way of doing tasks like installing drupal, clearing cache, and other things). I am also wanting to do a database and save/execute through multiple objects and site profiles. My general question is this. Which language would be better suited to handle command line code? Drupal is written in PHP so I am leaned more towards that,but I know python seems to handle console programming a bit easier. Any help would be great!

• Are there any companies using BDD in a .NET environment?

  - by Nick

  I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

• Why isn't Java more widely used for game development?

  - by Anto

  I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

• Microsoft StyleCop is now Open Source

  - by Scott Dorman

  I have previously talked about Microsoft StyleCop. For those that might not know about it, StyleCop is a source analysis tool (different from the static analysis that FxCop performs) that analyzes the source code directly. As a result, it focuses on more design (or style) issues such as layout, readability and documentation. In an interesting move (and one that I am happy to see), Microsoft has decided to make StyleCop an open source project (under the MS-PL license) available on CodePlex. (The project site isn’t up  yet, but should be in the next few weeks.) This will give the development community the opportunity to help contribute to the project, expanding support to other languages (currently it only supports C#), adding features, and fixing bugs. Shortly after the CodePlex site is up, StyleCop 4.4 will be released which includes support for C# 4.0 as well as a large number of bug fixes and other improvements.

• Physical effects of long term keyboard use- what does the science say and what factors affect it?

  - by glenatron

  This question asks about the ergonomics of a particular keyboard for long programming hours, what I would like to know is about the ergonomics of using a keyboard in general. What are the most significant risks associated with it and how can they best be mitigated? Do the "ergonomic" keyboard designs make a difference and if so which design is most effective? If not do other factors such as wrist-rests, regular exercise or having a suitable height of chair or desk make a difference? Do you have any direct experience of problems deriving from keyboard use and if so how did you resolve them? Is there any good science on this and if so what does it indicate? Edited to add: Wikipedia suggests that there are no proven advantages to "ergonomic" keyboards, but their citation seems pretty old- is that still the current state of play?

• Visual programming for serious software

  - by Gerenuk

  Are visual program control flow diagrams and languages which support that used for larger serious programs? Why not? They seem like a nice overview of the code. In the thread What software programming languages were used by the Soviet Union's space program? a visual language is mentioned (Drakon) and I wondered why such approaches aren't used more often? Is there nothing a visual control flow representation (I don't mean class diagrams etc.) which are 1-to-1 with code can help compared to typing in letters in an editor?

• C#/.net features to cut off assuming no backward compatibility needed?

  - by Gulshan

  Any product or framework evolves. Mainly it's done to catch up the needs of it's users, leverage new computing powers and simply make it better. Sometimes the primary design goal also changes with the product. C# or .net framework is no exception. As we see, the present day 4th version is very much different comparing with the first one. But thing comes as a barricade to this evolution- backward compatibility. In most of frameworks/products there are features would have been cut off if there was no need to support backward compatibility. According to you, what are these features in C#/.net? Please mention one feature per answer.

• Is there a IRC Client which can use or emulate mIRC scripts

  - by fred.bear

  I've used mIRC (Windows) for years, and have some custom scripts, written in mIRC's own scripting language. Is there an Ubuntu/Linux IRC Client which will allow me to use my scripts as-is? Failing that, is there a "functions a lot like mIRC" Client available? I've just tried Pidgin's IRC client, but it seems to be quite basic. I couldn't see any way for it to tap into channel activity via scripts. I don't want to use Wine... WineHQ reports it as having too many bugs for my liking, and anyhow, I try to avoid using Wine like I do Windows :)

• Return to the old C days.

  - by RPK

  Long back I used to program on C and than VB exploitation changed the career path. After VB came the .NET that proved to be a HoneyPot of Microsoft for old VB programmers and frustrated programmers of other hard to learn languages. The label on this HoneyPot was: "Getting things done." I now want to contribute to the Linux and other GNU projects. I feel whatever programming language you learn today, but if programming is your bread-and-butter, you must remain in touch with C. Many things have changed now. From the old Turbo-C for DOS to the present ...? Please advise me how to get back on the C track again. Reading again whole thing, chapter-by-chapter is not possible now, but I can learn by writing small utilities type of things, but sure GUI based. And yes, I hope, learning is going to be easy now with so many live forums and active community spots like StackOverflow etc.

• How do I learn Python from zero to web development? [closed]

  - by Terence Ponce

  I am looking into learning Python for web development. Assuming I already have some basic web development experience with Java (JSP/Servlets), I'm already familiar with web design (HTML, CSS, JS), basic programming concepts and that I am completely new to Python, how do I go about learning Python in a structured manner that will eventually lead me to web development with Python and Django? I'm not in a hurry to make web applications in Python so I really want to learn it thoroughly so as not to leave any gaps in my knowledge of the technologies involving web development in Python. Are there any books, resource or techniques to help me in my endeavor? In what order should I do/read them? UPDATE: When I say learning in a structured manner, I mean starting out from the basics then learning the advanced stuff without leaving some of the important details/features that Python has to offer. I want to know how to apply the things that I already know in programming to Python.

• How do you develop web applications? [closed]

  - by ck3g

  How do you and/or your team develop your web applications? Language, framework or platform doesn't matter. I would like to know about the structure of your environment. For example: Using IDE on workstation and project files on remote host accessing via sftp. Files are saved instantly on remote host; All files are local and are uploaded on remote host during saving; Files are local, web server is running on local computer and is tested at local host. etc. You could write down also about the benefits of your approach, this will be useful for me. Thanks upd: Here must be a question and here it is: which is the best approach by your opinion?

• Programming knowledge vs. programming logic

  - by Shirish11

  Is there any difference between the two topics? I have seen companies asking for Good Programming knowledge some Good Programming logic. I believe that Programming knowledge is related to knowledge about the language in consideration and Programming logic is problem solving logic using programming (in general). Please correct me if I am wrong. Also what is more important. Edit: Do selection of components for application, designing interfaces validating user inputs fall under programming knowledge or Programming logic? Does programming logic simply imply problem solving, or is there anything else which it should comprise of?

But I think that having this understanding is going to be very helpful moving forward"

• R vs Python for data analysis

  - by The_Cthulhu_Kid

  I have been programming for about a year and I am really interested in data analysis and machine learning. I am taking part in a couple of online courses and am reading a couple of books. Everything I am doing uses either R or Python and I am looking for suggestions on whether or not I should concentrate on one language (and if so which) or carry on with both; do they complement each other? -- I should mention that I use C# in school but am familiar with Python through self-study.

• F# open source project hosting using SVN

  - by Stephen Swensen

  Hi all, I'm looking to choose open source project hosting site for an F# project using SVN. CodePlex is where the .NET community in general and most F# projects are hosted, but I'm worried TFS + SvnBridge is going to give me headaches. So I'm looking elsewhere and seeking advice here. Or if you think CodePlex is still the best choice in my scenario, I'd like to hear that too. So far, Google Code is looking appealing to me. They have a clean interface and true SVN hosting. But there are close to no F# projects currently hosted (it's not even in their search by programming language list), so I'm wondering if there are any notable downsides besides the lack of community I might encounter. If there is yet another option, I'd like to hear that too. Thanks!

• So long wizards!

  - by geekrutherford

  In an effort to make an application more robust I have been switching to a server-side method of tracking record selections vs. client side.   The pages relying on record selections utilized the ASP.NET Wizard control which seemed like a good idea originally. Unfortunately, the design of the control is not all that flexible. It appears to want to center everything vertically which might not be a problem if it did not always use the vertical size of the largest Wizard Step for positioning.   So, I am ripping out the Wizard controls and replacing with simple Panel controls that are turned on/off. Much cleaner and presentable.

• Applying languages / locale selectively: is it possible?

  - by Aron Rotteveel

  I am a Dutch user and prefer the my local date & time format, system wide. I have no trouble speaking or understanding English and find it very useful to have the rest of my system configured in English to make my life easier when I need to Google a term, for example. Is it possible to apply the a local date/time/currency/etc. format to the system, while maintaining English menu & dialog captions? EDIT: output from locale and posted screens of current settings: LANG=en_US.utf8 LANGUAGE=en LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" LC_COLLATE="en_US.utf8" LC_MONETARY="en_US.utf8" LC_MESSAGES="en_US.utf8" LC_PAPER="en_US.utf8" LC_NAME="en_US.utf8" LC_ADDRESS="en_US.utf8" LC_TELEPHONE="en_US.utf8" LC_MEASUREMENT="en_US.utf8" LC_IDENTIFICATION="en_US.utf8" LC_ALL=

• How to do a cacheable redirection?

  - by John Doe

  When users enter my website example.com, their "preferred" language is detected and they are redirected (using a 301 Moved Permanently redirection) to example.com/en/ (for english), example.com/it/ (for italian), etc. It works perfectly, but when I analized my website with the Google Page Speed tool it gave me the following advice. Many pages, especially mobile pages, redirect users to a different URL, for instance from www.example.com to m.example.com. Making this redirect cacheable by the user's browser can speed up page load times for repeat visitors to a site. And later it says We recommend using a 302 redirect with a cache lifetime of one day. The redirect should include a Vary: User-Agent header as well as a Cache-Control: private header. So my questions are, how can I do a "cacheable" redirection in PHP? Would the following be enough? header("HTTP/1.0 302 Moved Temporarily"); header("Location: example.com/whatever"); exit;
