• Game Development In C Only. Is it possible?

  - by Ishan Sharma

  I am a first year college student in India and want to make a small game as a this semester project. I am quite good at C and am learning it rapidly but I wanted to ask if developing a game entirely in C (no C++ or C#) I'd love to use these but for college projects, we have strict requirements of using only C. What I am looking for is a simple top view driving game. It won't have anything fancy and even the visual things will be powered by simple characters. For example, user controlled car can be represented by ¦ and edges of road by series of |'s. What do you think?

• How does thumbnail preview in Ubuntu differ from that of Windows? [closed]

  - by Forbidden Overseer

  Possible Duplicate: How does Ubuntu know what file type a file without extension is I thought this question might get a better response in AskUbuntu, as it seems to have more to do with Ubuntu than Windows at a glance. Let's say I have a foo.mkv file. Thumbnail previews work in both Windows 7 and Ubuntu. When I change the filename to anything random like foo.bar or when I remove the extension itself (making it just foo), Nautilus shows thumbnails normally like if it can recognize what type of files they are - without looking at file extension. This however, doesn't happen in Windows 7. Windows starts asking me things like which application I want to use to open that file as soon as I remove file extension (forget thumbnails...) etc. So, How does this thumbnail preview work in Windows 7 and Ubuntu? What makes Ubuntu recognize files "out of the box" unlike Windows 7?

• GNOME Desktop fonts problem debacle

  - by Diogenes Lantern

  I didn't get an answer but I wasn't doing anything and this is an interesting topic. In Ubuntu 12.04, opening a file in gedit or I am working on the command line, in dpkg, I get returned the error "locale not supported, falling back to default "C" libraries", and the one below, Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale. The locales were not set correctly, and locale LANG and LANGUAGE were the culprits. I picked my way through this. The answer, correct below.

• Ubuntu freezes when gdm starts

  - by Enrique

  I have Ubuntu 10.10 (upgraded from 10.04) I was browsing in Firefox yesterday, then the PC suddenly did a reset Once it restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I can't move mouse pointer nor do anything with keyboard at this point (just after userlist shows in gdm). PS: Both, mouse and keyboard work fine, because this Ubuntu is dual-booting with a Windows XP install which loads/works fine. Here is my .xsession-errors file, but I don't have a clue what may be wrong. Thanks http://pastebin.com/GVtneEAF

• Are things slow for you today - Check your DNS

  - by simonsabin

  Domain name resolution is a very common cause of delays when doing anything over the network whether its accessing a web page or connecting to SQL Server. Everything uses DNS. TCP/IP works with IP addresses and not friendly names. When using names you have to have a way of resolving names to IP addresses and thats what DNS does. If your DNS is wrong then you'll get delays and also potentially odd results. For instance if you have multiple DNS servers configured you may find that occasionally...(read more)

• Writing drivers for a printer?

  - by user828584

  My goal is to be able to fax 20 page pdf documents for free. I've looked online, and there are some free fax services, but all of them have their limits. I do have an old fax machine, but the documents that need to be faxed are on the computer, and to print them would be far from free. Unfortunately, the only way to send a fax with the machine is by scanning it. What's strange is that it can scan to the computer and print from it, but it won't fax from it... :(. Is it possible to write something (preferably C#, but it's going to take some learning anyway) that will allow me to send a fax from the computer? I have very little software experience, and none in anything like this, so I have no idea where to start. If it is possible, where can I find all the information needed to write the program?

• why doesn't cron complete script

  - by brickinthewall

  i have a backup script (rsync via ssh) which is run by cron (configured in /etc/crontab) 0 2 * * * root /bin/bash --login /opt/aebackup/sshbackup.sh if i run it as logged in root like following it runs prefectly fine. root@server:~# /opt/aebackup/sshbackup.sh if i run it via cron it would just stop after a while (not always on the same task in the script.. it seems pretty random, like the process is killed at some point randomly) does anyone have an idea why my cron would do that? thanks for anything.. i'm desperate!

• GPG Workflow in 11.04

  - by Ross Bearman

  At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website. Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, making it unusable and it will no longer install in FF5. Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling large amount of these small files throughout the day this starts to become a real chore. I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal. So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.

• Years experience over unfinished degree?

  - by Daniel Lewis

  I'm currently in my placement year and working for a great software development company. It was always my intention of getting to this stage through university, getting enough academic experience as well as the year’s placement and then try to get a full time programming job without the need to finish my degree. I decided this from an early stage as I have never really liked the whole university environment. I was so unhappy at university and I’m so happy now I’m on my placement year, I really don’t know if I can go back. My question is, do you think companies will take me on if I apply for other jobs after my placement year and not penalize me for not finishing my degree? I guess at the end of the day I don't want to look back on my life and think "god, why didn't I just spend one more year being unhappy to have a job I love" but I know that even if I get a degree I could still end up without a programming job and this worries me more than anything.

• Git doesn't sync files until committed, even if checked out in a different branch

  - by DertWaiter

  Okay, I have git 1.7.11.1 on Windows and I have a local test repository with 2 branches. One is master with index.php and help.php. I then create another branch called slave :) I run from git bash rm help.php and it disappears from the folder, but I don't stage anything. I switch to checkout master branch and it is supposed to restore file help.php because it is not modified in the master branch, isn't it? And it does not do it. When I go back to the slave branch and commit and then switch to checkout master then help.php appears. Is that the way it is supposed to to work? Why?

• reasonably priced registrar for obscure tlds like .tt

  - by Stu

  I'm looking to buy a .tt domain name, however the only registrars I can find want from between $500 to $3000 for one domain. Considering I can buy a .com for around $10 a year, I consider that not very reasonable! It's going to be for a personal blog site (non monetised), hence why I'm not willing to spend over $500 a year on it. Does anyone know of any registrars that sell obscure tld's such as .tt for reasonable price? As for my definition of "reasonable", I understand it's not a .com and I'm going to have to pay more, but $3000 is just silly! In my opinion I'd say anything under $100 is reasonable.

• Syncing objects to a remote server, and caching on local storage

  - by Harry

  What's the best method of sycing objects (as JSON) to a remote server, with local caching? I have some objects that will pretty much just be plain-text with some extra meta-data. I was thinking of perhaps including a "last modified date" for both Local storage and Remote storage. This could then be used to determine which object is the most recent. For example, even though objects will be saved to both local and remote when they are saved, sometimes the user may not have internet access, or the server may be down, or any other number of things. In this case, the last modified date for remote storage would be reverted to its previous date. Local storage would remain as it is. At this point, the user could exit the application, and when they reload the application would then look at the last modified dates of the local and remote storages, and decide. Is there anything I'm missing with this? Is there a better method that I could use?

• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• Custom .NET apps and clustering

  - by Ahmed ilyas

  So for a clustered environment - how would this work with your apps? what about your own custom .NET apps? Would there be a special way to develop them? I know that you can say create a simple Hello world app, and cluster that but they wouldnt be something you could see interms of the UI or anything, so they would effectively need to be developed as a Windows Service perhaps or even as a standard Console app which runs and not wait for user input but you wouldnt see any output from it (unless you redirect output to somewhere else) What im getting at here is... for those who have experience or developed a cluster application in .NET, how did you do it and what are the things to be aware of? For example we have the cloud service - fundamentally its built on clustering - if there is an outage, another node takes place and service is resumed as normal but we dont really see much of that downtime.

• Is this fix for Avast Antivirus crashing safe to use?

  - by TmRn

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: Press Ctrl+Alt+T to open the Terminal. When it opens, run the command below. sudo gedit /etc/init.d/rcS Type your password and hit Enter. When the text file opens, add the line: sysctl -w kernel.shmmax=128000000 Make sure the line you added is before: exec /etc/init.d/rc S This is what it should look like: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S Save the file. Reboot. My question is: Did I do anything wrong? I mean as I have made some tweaks, will it lower the security of Avast down like viruses do? Please if you are a programmer check this if it contains bug or harmful intentions... Thanks.

• Most Useful New Technology?

  - by Craig Ferguson

  I'm looking to take a sort of sabbatical, and I'd love to use it to learn a new technology. My question is this: What's the most useful "new" technology for a software engineer to use? Node.js, iOS programming, Android, something else? I'd prefer to stay away from anything too new or experimental, since those are, in my experience, rarely actually used in professional production environments (for better or worse). Does anyone happen to have stats on how many jobs there are for each new technology or have anecdotes about how fun each one is? I've been using python/Django, so that's out, and it's similar to Ruby so i don't think learning Ruby would be that useful to expanding my skills. Anyone have any other ideas?

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• Countour Mapping API

  - by Crash

  I have done some searching on Google, but haven't come up with much as of yet. I am wanting to take a set of point data, which I had previously been using to create weighted points for a heat map through the Google API, and turn them into a contour map to overlay on the Google Maps API. I haven't seen anything in Google's code that would let me do this. Does anyone know of a good API to create such an overlay? Or is there possibly something I have overlooked that Google offers?

• How will the search rank get impacted if i move my mobile website to a single page application?

  - by rahul

  I have two different versions of my site. A desktop version and a mobile optimised version. That is for the same url the server renders different html for different user agents. I had been using vary header for this scheme as recommended by Google. However, now i want to move the mobile website to a single page application for several reasons. I want to know if google stops seeing anything on my mobile web version but the desktop version continues to work as it is, then how would the search rank be impacted given that mobile web gets more traffic than the desktop version. How would the vary header come jnto play

• How to make game menu Java

  - by Deathsbreed

  I've been searching all over for how to make a game menu, but I haven't found anything useful. I have a very simple Pong like game (source-code here), and I want to add a main menu to it. This wouldn't be too much of a problem if I was making a standalone with JFrame instead of an Applet, but I want this to be available on the web (not downloaded). I might have been able to do some of it myself, except for the fact that it would mean having a very heavy main class (in this case the GNP.java file). So I was thinking, is there a way to basically have a Java Applet and have it use a JFrame and how? and if not, what could I do? Thanks!

• Where to install bootloader when installing Ubuntu as secondary OS?

  - by HelpNeeder

  I'm trying to install Ubuntu as secondary OS on my laptop. I have Windows 8 already installed on my laptop. Now, I know how to run Ubuntu from USB drive, I created addition partition and formatted it to EXT4. So I'm ready to install. Now, 'Device for boot loader installation:' displays: /dev/sta ATA HITACHI (750 GB) /dev/sta1 Windows 8 (loader) /dev/sta2 /dev/sta5 /dev/sta6 Ubuntu 12.04 (12.04) /dev/stb I tries choosing Ubuntu 12.04 partition but it doesn't even let me to pick which OS to install and goes straight to Windows 8. Which partition I must choose to be able to pick which OS to boot from? Preferably, set up so Windows 8 will be at first place, and Ubuntu on second. Any ideas? I don't want to mess up anything if I pick something wrong.

• Chinese bots in my forum

  - by TdotThomas

  I have a small community forum that doesn't really get posts or any real traffic. The only thing that happens on the regular is bots with Chinese IPs signing up gibberish usernames. Most bots don't make it past the captcha but some do. I try to stay on top of this by banning IPs and ranges of IPs but it doesn't really seem to help. The bots never post anything so what are they doing? Should I be worried? Should I keep banning IPs or is it futile?

• Ubuntu 12.10 WiFi Problems

  - by Sean Webber

  I have a 32 bit machine running Ubuntu 12.10 with WiFi on it. I have a WPA2 network at home, but if I leave the USB Adapter plugged in while it boots, it infinitely keeps asking for the network password but never connects. If I plug it in after boot, it will connect but then I can't access ANYTHING on the LAN or Internet because "the DNS servers are unreachable". Now, if I leave the computer on a while, I get lucky sometimes and it MAGICALLY decides to connect for a little bit, lock the machine though and the Internet's gone again. The weirdest thing, is when I am connected but can't get to the internet, I do a netstat or ifconfig wlan0, I do have an IP address and everything. It says I'm connected but its not. I have a Realtek RTL8188CU USB adapter.

• How to make a table structure for products to be available for both wholesale and retail?

  - by kmy

  Ignoring the different column details like colors, shapes, and sizes, I already have an idea of dealing with that, I'm more interested in dealing with retail pricing, whole pricing (with or without a table), and possibly discount. If anything, I want to know what I should also take account for. Will it just be adding a quantity column, two pricing cols, and two discount columns, and a quantity limit? If I were to add a pricing table it would be inserted as a json file, would this be a bad idea? Please give any insight about this.

• Free Models and Related Animations for AI project in Unity [on hold]

  - by zhed

  Does anybody know a good website where to find free models and animations for AI projects? I'm not talking about anything good looking, like stuff you would look for when building a proper game, but, for example, a bunch of male/female models that are able to walk around and that would substitute my ugly "capsules", just to give a better -yet, still rough - idea of what's going on in the scene. On the Unity Asset Store there are a bunch of nice male/female models, but i haven't found any free general-purpose(i.e. normal walking) animation attachable to them. Any tip would we appreciated, thanks :)
