  • Making it myself vs. modifying someone else's code as a beginner

    - by JamesGold
    I just started getting into open source projects mainly for the learning experience. I've made a few tiny contributions to some small projects. Most of my time has been spent just reading over other people's code and trying to understand how it works. Often times I find myself frustrated by a lack of documentation and unit tests. There are also times where I think I can see a more intuitive solution to a problem, but implementing it would require large restructuring of code. I see all this and wonder to myself why I don't just start clean on the whole thing by myself and do things "the right way"? I'd also enjoy the experience of building it from scratch, as it would force me to learn skills that I might not learn by working on other people's code. On the other hand, working on other people's code is also a great experience because it requires me to understand and work with other people's code and collaborate with them. It's just harder, IMO. Thoughts?

  • Installing dgen removes Ubuntu-Desktop

    - by aliasbody
    I am trying to install "dgen" a Sega MegaDrive/Genesis emulator, available in the official Ubuntu repositories. But when I try to install, the package manager (USC or even apt-get), say's that he needs to remove those packages before installing : file-roller lintian ubuntu-desktop unzip winetricks Ubuntu always had problems with dependencies like this, and this was the main raison I started using Arch Linux instead of Ubuntu, but with the newest versions (mainly the 12.04 version), I was hopping that those kind of problems had complety dissapeared.. but no :S... So, How can I install this package without removing those packages ? And do I need to fill a bug report for this ?

  • Windows 7/Ubuntu 12 dual boot deleted for Windows 8 installation. How to make grub rescue go away?

    - by dimious
    I had a Windows 7/Ubuntu 12 dual boot and I decided to clean install Windows 8 over them. The problem is that after I deleted all partitions and installed windows I was getting an "Operation system not found", however after an "enter" the system will normally boot into Windows 8. I realized that Windows did their trick and put the system (not partition anymore?!?) "tag" (Disk Management) on my media hard drive. After trying to fix the boot/mbr to be able to boot from my main drive the "Operation system not found" changed to the "grub rescue" prompt. I know that I cannot use that because I have killed the grub files. Windows can still boot as long as I choose to boot from the media drive. The question is, is there any way to move the "system", whatever it is now, to the main drive and have the PC boot from there, while making grub disappear? And if that is possible after that, can I just make the Media drive inactive or I will have to somehow remove the "system" tag?

  • Xubuntu keeps loading on install with usb stick

    - by mattyh88
    I'm trying to install Xubuntu on my computer. I've followed a guide to create a USB bootable drive. I've inserted the USB stick and started the computer. I can see Xubuntu loading and after a minute or 2 it shows me a screen asking me if I'd like to use the live version or if I'd like to install. I choose install. Then on the next screen I select English as language. When I click continue, Xubuntu just keeps loading. It doesn't really freeze as I can still quit and move the cursor. When I clicked quit, I see the live version and all is working just fine. I can browse the internet, etc. What could be wrong?

  • Education and Career Resources from Microsoft and the Community

    - by KKline
    Sometimes I'm timely in getting the news out on useful resources. And, other times, I'm a bit slower on the draw. As I told my friends back at New Year's Day, "As an official member of the Procrastinators Club, welcome to 2008!" On the other hand, it's always good to remind folks of great resources that are still available and on the shelf. Why? Well, the Internet hits us with such a deluge of constantly new material, that we often forget about the old(ish) stuff that's still really useful. Darth...(read more)

  • Develop open-source library and get donations for it?

    - by Robottinosino
    I have a nice open-source library in mind to write. It would take a few months to develop properly and I would need to stop supporting myself though other projects. Could anybody share experiences and best-known-methods to get some sort of financial support through the Internet whilst developing free, open-source code? Or, phrased more directly: which systems apart from "PayPal" are in use by programmers to get donations for open-source code? Provide a list. Optionally, sort the list as if it were a recommendation in descending order of positive experiences made with each system. Optionally, share a tidbit of your success story getting this kind of financial support. Optionally: give an indication as to how much money can be made that way? (I heard Vim's author could support himself just with donations at some point?)

  • As a software architect, am I supposed to focus that much on analysing the logs and fixing other's bugs?

    - by Hatem81
    Since my graduation (late 2005) I was working for the same company as a c++ software engineer. A year ago I was promoted as a software architect but I have found myself involved more and more in qualification and fixing bugs, level 2 support. 50% of my time spent in Notepad++ analysing the software logs and trying to figure out what went wrong. 30% fixing other's bugs and the remaining (if any) reviewing developers spaghetti code. I started hating this product and thinking about an exit strategy out of this company. What do you think I can do in this situation? do you other software architect still fixing bugs in the code?

  • WebFX: Running JavaFX as web page

    - by Bruno.Borges
    This weekend I wanted to learn JavaFX, so I decided to code an idea I had a few years ago when I first saw JavaFX Script. So I started coding a web browser that runs HTML with the awesome, HTML5 supported WebView. But this browser also offers one extra feature: it loads FXML files as if they were HTML. So instead of defining your web page with HTML and running with WebKit, you can define a web page with FXML+CSS+JS and run as a JavaFX application. The project is called WebFX and already has a prototype on GitHub. I also uploaded a video on YouTube demonstrating the idea. What do you think about using JavaFX in the future for web pages, instead of HTML?

  • Boot Failure: No default or UI configuration directive found Normal install on laptop [closed]

    - by user79920
    I have had Ubuntu on my laptop for quite a while, it's just a standard install, no partitioning off, no wierdness of any other sort, just ubuntu. Today my computer started to lag really bad so I tried to restart it, but after bios loaded I just got an error that said "ERROR: No configuration file found No DEFAULT or UI configuration directive found!" After that it had "boot:" and a cursor, like it expects me to type something. Once again, this is just a normal install on my hard drive, not a VM or booting from USB. It's Ubuntu 12.04 on a Sony Vaio VGN-SZ240P Any help is appreciated!

  • Best Resources for learning SQL? [closed]

    - by Simon
    Possible Duplicate: Good Books and videos for absolute beginner to SQL I have landed a role as a product engineer for a web based product. A big part of the product is allowing its users the ability to create queries with SQL to pull in business information from their back end databases. I know the very basics of SQL and need to spend some time getting a better grasp on SQL. I have the tutorial from w3schools on my ToDo list, but was hoping to get some answers that point me to good resources for learning SQL. I have no preference - I can buy a book (SQL For Dummies?), or online resources, online videos, audio, etc.

  • How to better start learning programming - with imperative or declarative languages?

    - by user712092
    Someone is interested in learning to program. What language paradigm should I recomend him - imperative or declarative? And what programming language should he start with? I think that declarative because it is closer to math. And I would say that Prolog might be the best start because it is based on logic and programs are short. On the other hand at school we started learning from imperative languages and I am not sure whether there is a benefit to start with them instead of declarive ones. Thanks. :)

  • Pendrive USB Ubuntu installation - black screen on boot

    - by ubuntico
    I see many posts on this, but no solution. I installed Ubuntu 12.04 on my 16GB USB flash drive using this official link using their tool Universal USB Installer. Installation to USB went fine so I set my laptop to boot from USB and the Ubuntu was recognized. I saw the usual boot screen and I chose option "Run Ubuntu from this USB". The boot process started and after 5-6 seconds the screen goes black and non-responsive. I thought that it hang on X loading so I tried switching to console via Ctrl+Alt+F1-6 but the system did not respond. Why is this happening? Am I doing something wrong? PS. My laptop is HP Pavillion G6

  • chmod 700 and htaccess deny from all enough?

    - by John Jenkins
    I would like to protect a public directory from public view. None of the files will ever be viewed online. I chmoded the directory to 700 and created an htaccess file that has "deny from all" inside it. Is this enough security or can a hacker still gain access to the files? I know some people will say that hackers can get into anything, but I just want to make sure that there isn't anything else I can do to make it harder to hack. Reply: I am asking if chmod 700 and deny from all is enough security alone to prevent hackers from getting my files. Thanks.

  • Application starts as Terminal but not as a Desktop entry

    - by Dcm1405
    I just installed SQL Anywhere 12 and can start Sybase Central from the terminal with the command line below without errors: /opt/sqlanywhere12/bin32/scjview However, when I try to start it from a desktop entry I am receiving two error messages that could be something incorrectly defined in the desktop below: #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_US]=gnome-panel-launcher Name[en_US]=Sybase Central Exec=/opt/sqlanywhere12/bin32/scjview Comment[en_US]= Name=Sybase Central Comment= Icon=gnome-panel-launcher Here are the error messages: (unable to post the error images) cannot find libsyblib610_r.so cannot find libulscutil12.so Since the application can be successfully started from a terminal window I was wondering how I could have it setup as a desktop entry as well.

  • Where to hire a scenario writer for a small interactive story game?

    - by Alexander Gladysh
    I need a scenario for a small dialog-based game / interactive story. The game would be used as an example for a middleware tool we're developing. I would like to buy an existing story (it should be dynamic of course — with branching dialogs etc.), or hire someone to write a new one. Please advise, where to go to find such person / service? We're based in Russia, so getting a talented enough native English writer locally is a bit of a problem. Update: To be extra clear: We must get all necessary rights to reuse the story and make a derived work (i.e. the game we're talking about) from it. This is a commercial product. Borrowing someone else's work at random and using it just not going to work.

  • Inexpensive generation of hierarchical unique IDs

    - by romaninsh
    My application is building a hierarchical structure like this: root = { 'id': 'root', 'children': [ { 'name': 'root_foo', 'children': [] }, { 'id': 'root_foo2', 'children': [ { 'id': 'root_foo2_bar', 'children': [] } ] } ] } in other words, it's a tree of nodes, where each node might have child elements and unique identifier I call "id". When a new child is added, I need to generate a unique identifier for it, however I have two problems: identifiers are getting too long adding many children takes slower, as I need to find first available id My requirement is: naming of a child X must be determined only from the state in their ancestors When I re-generate tree with same contents, the IDs must be same or in other words, when we have nodes A and B, creating child in A, must not affect the name given to children of B. I know that one way to optimize would be to introduce counter in each node and append it to the names which will solve my performance issue, but will not address the issue with the "long identifiers". Could you suggest me the algorithm for quickly coming up with new IDs?

  • What are the files in /dev/input/ and what they do?

    - by Pouya
    I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

  • Why is 2^16 a "special" number?

    - by javamonkey79
    OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

  • Any tips to learn how to program with severe ADHD?

    - by twinbornJoint
    I have a difficult time trying to learn how to program from straight text-books. Video training seems to work well for me in my past experiences with PHP. I am trying my hardest to stay focussed and push through. Specifically I am looking to start indie game development. Over the last two weeks I have been trying to pick the "right" language and framework to develop with. I started going through Python, but I am not really enjoying the language so far. I am constantly looking through this website to compare this language to that, and keep getting distracted. Aside from all of this, is it possible to become a programmer when you have trouble focussing? Has anyone been through this that can recommend some advice? edit - you guys can check my new question out with detailed information thanks to all of the responses from this thread. http://programmers.stackexchange.com/questions/15916/what-is-the-best-language-and-framework-for-my-situation

  • help redirecting IP address

    - by Alice
    Google has indexed the IP address of my site rather than the domain, so now I'm trying to set up a 301 redirect that will redirect the IP address and all subsequent pages to the domain. I currently have something like this in my .htaccess file (however don't think it's working correctly?): RewriteCond %{HTTP_HOST} ^12.34.567.890 RewriteRule (.*) (domain address)/$1 [R=301,L] I've used various redirect checker tools and keep getting the message: "... not redirecting to any URL or the redirect is NOT SEARCH ENGINE FRIENDLY" Am I doing something wrong or is there something else I should be trying? Thanks! Alice

  • From Imperative to Functional Programming

    - by user66569
    As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

    SharePoint 2010 Training: more information This is one of those rare occasions when I get to write about what I’m working on in my consulting life. I’m a very lucky guy, I get to work on some very tough and challenging solutions for clients around the world. In working on such problems, I face the best challenges which help me be a better consultant. A better consultant is a better trainer. There is no substitute for real world experience. As an example, Winsmarts started working on a product with Din ERP that would bring ERP functionality into SharePoint. Not influenced by marketecture, and the only driver being success at customer, as an architect for this endeavor, I experimented with and decided against technologies such as Silverlight. We subsequently invested heavily in JavaScript when the prevalent browser was still IE6. It wasn’t easy to create an amazing amount of functionality in JavaScript, but over time we enriched the product and today we have a very compelling Read full article ....

  • FGLRX Drivers Keep Crashing | "Installation Media" reads Natty even though I'm in Precise

    - by Tom Thorogood
    I recently switched back to Ubuntu after a year or so of hardly touching my Ubuntu partition, and upgraded from Natty. Every time I start up, i get the "A problem has occurred..." popup, but it won't let me report it because Precise is not in beta. The details on the report show a segfault, and going through all the details, I notice that it lists Natty under "InstallationMedia" -- I just installed these drivers, so I'm really unsure why it's saying this. I wish I could copy this entire error report, but I see no way of doing that (is it stored somewhere in /var/log?). I'm new to the Unity interface (it's why I stopped using Ubuntu to begin with, but now that I'm getting used to it I'm liking it better). Thanks.

  • Question about SEO and Domains

    - by jasondavis
    This is my first post on here as I am mainly on Stackoverflow and Serverfault. I have been programming for at least 10 years now, have made hundreds of websites but I have just recently started getting into Design and the SEO side of sites, sad that I have been overlooking these for so many years. I have pretty good knowledge from all my years of SEO but I have never really looked into it until now. My question, I would like to build a site that targets many different key words for the search engines, for an example. Let's say I built a site about Outdoor activities called outdoorreview.com and I planned on having many sections hunting fishing Hiking camping cycling climbing etc... For best Search Engine results, how could I get the most search engine traffic to all these ares? Also how should I structure the way to get to them, outdoorreview.com/Hiking/ or hiking.outdoorreview.com ?
