• Am I bored with programming? [closed]

  - by user1167074

  I have started programming 2 years back and I have learnt web programming while working for big corporate companies. I was very passionate and I even did couple of side projects which were well appreciated by my friends and colleagues. But for the past 2 months I am not doing anything really interesting with programming, even if I get good ideas I am not feeling like coding, sub consciously I am feeling like "So What?" if I do this project. I would like to know from the more experienced programmers if this is just a phase or am I really missing something? Thanks

• How to write a network game?

  - by TomWij

  Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

• Keep only essential packages

  - by Stijn

  In an attempt to learn more about Ubuntu and its packages, I want to remove all non-essential packages, so I can install what I need, when I need them and know what they do. I'm using the commands dpkg --clear-selections and apt-get dselect-upgrade for this. I also slightly modify the selection by setting apt libstdc++6 (due to apt) install-info (due to grep) to install again (somehow dpkg thinks they are not essential, but apt-get complains). Is this ok, or is this bad? If it's ok, what do I do with the large list of packages with "deinstall" status in dpkg? An additional note, I'm doing this on a VPS template so I have no control over the initially installed packages.

• Needs management tool for .java files

  - by Chris Okyen

  When I open the src file in the project folder in Package Explorer in Eclipse, it says the following: Error retrieving content description for resource '/GuiAdd/src/GuiAdd.Java.' Now, the directories of the source projects shown in Eclipse Package explorer doesn't always have the source file to link to, causing this message. I need a way to sync the folders in the correct directory without overwriting the newest ones. Some source files I project files of the root which the Package explorer links to may be the correct versions but other source files in the root may not have the latest source or any source. I am not using svn/git or other depository programs.

• When to use an Array vs When to use a Vector, when dealing with GameObjects?

  - by user32465

  I understand that from other answers, Arrays and Vectors are the best choices. Many on SE claim that Linked Lists and Maps are bad for video game programming. I understand that for the most part, I can use Arrays. However, I don't really understand exactly when to use Vectors over Arrays. Why even use Vectors? Wouldn't it be best if I simply always used an Array, that way I know how much memory my game needs? Specifically my game would only ever load a single "Map" area of tiles, such as Map[100][100], so I could very easily have an array of GameObjectContainer GameObjects[100][100], which would reserve an entire map's worth of possible gameobjects, correct? So why use a Vector instead? Memory is quite large on modern hardware.

• Java dev learning Python: what concepts do I need to wrap my head around?

  - by LRE

  I've run through a few tutorials and written some small projects. I'm right in the middle of a small project now infact. All is going well enough thanks in no small part to Uncle Google (who usually points me to Stackoverflow ;-) Several times in the last few days I've found myself wondering "what am I missing?" - I feel that I'm still thinking in Java as I write in Python. This question over at StackOverflow is full of tips about what resources to read up on for learning Python, but I still feel that I'm a Java dev with a dictionary (no pun intended) to translate into Python. What I really want to do is refactor my head to be able to write Pythonic Python instead of Java disguised as Python (not that I want to loose my Java skills). So, the crux of my question is: what concepts does a Java dev really need to learn to think Pythonic? This includes anything that needs to be un-learnt. ps: I consider language syntax to not be particularly relevant to this question.

• Testing To Prevent Cascading Bugs

  - by jfrankcarr

  Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

• What's your worst open source experience?

  - by Fanatic23

  I recently tried downloading a pretty popular open source project [its got 10+ tags of different kinds on SO] which in turn depends on another open source project. The 2 projects built fine, but when it came to linking these 2 with my final executable there are like loads of missing symbols. No mention of which version of project 1 is compatible with project 2 etc. What's been your's most difficult open source experience? Mind you, I am all for open source but documentation and examples seem to be a key missing area.

• Can/should one record unstructured suggestions and feedback in an issue tracker?

  - by Ian Mackinnon

  I'd like to advocate the use of issue-tracking software within an organisation that currently does not use it. But there's one aspect of their situation for which I'm unsure of what to suggest: their projects frequently receive informal verbal feedback or casual comments in meetings or in passing from a wide group of interested parties, and all this information needs to be recorded. Most of these messages are noise, but they're vital to record and share with developers for two reasons: Good suggestions often come out of this process. It can be necessary to have evidence of clients' comments when they forget previous instructions or change their mind. Is this the sort of information that should be stored in an issue-tracking system, or kept apart in a separate solution? Are there issue-tracking systems that have particularly good support for this sort of unstructured information?

• ADF is YouTubed

  - by Chris Muir

  A blog post along the lines of "your wishes are our command". ADF developers are hopefully aware of our ADF Insider Essentials recordings, a page full of presentations from small to large topics on all-things-ADF.  A couple of customers have pointed out these recordings aren't accessible via the iPad and other Apple OSX devices thanks to the recordings being wrapped in an Adobe Flash applet. To satisfy this need we've now uploaded all of the videos as MP4s to our ADF Insider Essentials YouTube channel for your iPad viewing pleasure.  So now regardless if you're sitting at your PC or on the couch with your iPad, you can enjoy my horrible Aussie accent amongst the more professional ADF presentations from my colleagues ;-) Make sure to subscribe to the YouTube channel to receive notifications of newly uploaded content.

• What do you look for when debugging deadlocks?

  - by Michael K

  Recently I've been working on projects that heavily use threading. I think that I'm OK at designing them; use stateless design as much as possible, lock access to all resources that more than one thread needs, etc. My experience in functional programming has helped that immensely. However, when reading other people's thread code, I get confused. I am debugging a deadlock right now, and since the coding style and design are different from my personal style, I am having a difficult time seeing potential deadlock conditions. What do you look for when debugging deadlocks?

• 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?)

• Hiding images in folder without renaming or moving the files

  - by Marcus

  I'm dual booting Ubuntu with Windows and I have all my music on a separate harddrive. In Windows the album art is hidden by default but when I access the folder in Ubuntu there is two album artwork files for every mp3, one small and one large. I would like to hide those images without having to rename them with a dot before or moving them to some other folder becuase then the album artwork would dissapear in Windows. Is there a way to make a .hidden file which hides all images or any other way which hides all images in nautilus?

• Turn Your Browser Pane into a Game of Katamari Damacy

  - by Jason Fitzpatrick

  If you’re a fan of Katamari Damacy, a quirky and fun Japanese puzzle game made popular on the PlayStation, you’ll love this Javas script hack that turns your browser pane and its contents into a giant HTML-collecting game of Katamari Damacy. Katamari Damacy, for the unfamiliar, is a addictive game based on the premise that a galactic prince is on a mission to rebuild stars, constellations, and moons accidentally destroyed by his father. You roll around and collect objects (making yourself an increasingly larger ball in the process). This script hack puts a ball on your web browser pane (works best in Chrome) that you can roll around collecting elements from the web page. At first you can only grab links but as you grow you can grab increasingly large objects like photo elements off the page. It doesn’t have the sophisticated graphics of the Playstation version, of course, nor the detailed back story, but it’s a clever little hack that is sure to delight fans of Katamari Damacy.

• Reasonable size for "filesystem reserved blocks" for non-OS disks?

  - by j-g-faustus

  When creating a file system ( mkfs ...) the file system reserves 5% of the space for its own use because, according to man tune2fs: Reserving some number of filesystem blocks for use by privileged processes is done to avoid filesystem fragmentation, and to allow system daemons, such as syslogd(8), to continue to function correctly after non-privileged processes are prevented from writing to the filesystem. But with large drives 5% is quite a lot of space. I have 4x1.5 TB drives for data storage (the OS runs on a separate disk), so the default setting would reserve 300 GB, which is an order of magnitude more than the the entire OS drive. The reserved space can be tweaked, but what is a reasonable size for a data disk? Can I set it to zero, or could that lead to issues with fragmentation?

• Working as a software developer in a small town [closed]

  - by James

  I'm thinking of moving back to a small town in the near future. Coming from a large city (Dallas), I'm worried about being able to find work as a developer. I've worked remotely for companies as a contractor before, but would prefer a full time position for health insurance. Has anyone successfully made a good career for themselves while living outside of a major city (the nearest big city will be Minneapolis, about 3 hours away)? If so, how did you do it and what steps could I take between now and then to maximize my chances for success?

• Why do software patches have to be accepted by a developer?

  - by Nigel

  In open source projects, why do software patches have to be accepted by a developer? Couldn't contributors just release their own patches and allow people to add the patch if they choose to. I'm wondering why there are so many Ubuntu programs that could use such obvious work but aren't updated. For instance, lots of people want Rhythmbox to be more attractive. Why can't the people who design themes on DeviantArt turn those into code and let users download those themes themselves, even if the developers at Rhythmbox won't accept different themes?

• Open source management game in java

  - by jcw

  I am trying to find an open source sport management game, much like the link below, but am failing to do so. There are two links provided in the below question that are both fine,'except for one minor problem - I only know java! Is there an open source sports manager project? After some googling, I have been unsuccessful in finding a sports management game that is written in java. I am do not particullarly care about the type of sport, becuase I am mostly interested in mechanics. Does anyone know of any such projects or am I out of luck on java?

• How to prepare a game for localization?

  - by kevin42

  Many projects don't think about localization until the game is done. Then localization is done as a hack, and it's obvious that it was added on later. Some specific areas of concern: Text strings (obviously) Audio clips such as music and/or narratives Text rendered on textures (e.g. a label on a crate) Text rendered in frames in pre-rendered movies Fonts/Character sets for different languages Etc. What are some good ways to prepare for these challenges in the initial development stages, so you can make it easier without incurring too much cost up front?

• Gzip compress offline?

  - by shoosh

  I've configured my site to serve compressed content by putting this line in .htaccess AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript text/css application/javascript application/json This works perfectly for almost all files except a few large JSON files that are above 200Kb. For some reason they are not being compressed. I see that they don't using the net tab in firebug and the Network section in chrome. So as a workaround I thought I could compress these files offline and have Apache read them compressed. What tool should I use to compress them? is the linux gzip the one? any special flags or something I should use? What should I put in .htaccess so that the server would know to serve these files with content-encoding gzip ?

• why would you use textures that are not a power of 2?

  - by Will

  In the early days of OpenGL and DirectX, it was required that textures were powers of two. This meant that interpolation of float values could be done very quickly using shifting and such. Since OpenGL 2.0, and preceding that via an extension, non-power-of-two texture dimensions has been supported. Are there performance advantages to sticking to power-of-two textures on modern integrated and discrete GPUs? What advantages do non-power-of-two textures have, if any? Are there large populations of desktop users who don't have cards that support non-power-of-two textures?

• What makes Erlang suitable for cloud applications?

  - by Duncan

  We are starting a new project and implementing on our corporations's instantiation of an openstack cloud (see http://www.openstack.org/). The project is security tooling for our corporation. We currently run many hundreds of dedicated servers for security tools and are moving them to our corporations instantiation of openstack. Other projects in my company currently use erlang in several distributed server applications, and other Q/A point out erlang is used in several popular cloud services. I am trying to convince others to consider where it might be applicable on our project. What are erlang's strengths for cloud programming? Where are areas it is particularly appropriate to use erlang?
