• Making a Living Developing Games

  - by cable729

  I'm in my last year of high school, and I've been looking at colleges. I'm taking a C++ class at a local community college and I don't feel that it's worth it. I could have learned everything in that class in a week. This had me thinking, would a CS degree even be worth it? How much can it teach me if I can learn everything on my own? Even if I do need to learn more advanced subjects, many colleges put their material online AND I can buy a book. Will companies hire me if I don't have a CS degree? If I have a portfolio will I stand a chance? What kind of things are needed in the portfolio? I want to live doing what I love - programming. So I will do it. I'm just not sure that a CS degree will do anything to me. In addition, if there is a benefit to getting a CS degree, what places are the best?

• Partition tool with console UI (as in server installation)?

  - by lepe

  Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

• Can't connect nonlocally after 12.10 upgrade

  - by user101815

  I've just upgraded one of my systems from 12.04 to 12.10. Now I can't connect on that system beyond my local network. Connections within the local network seem to work fine, and I can make nonlocal connections from other machines (like the one I'm asking this question from). I suspect that some routing information has been messed up, but I don't know where to look for it. It's not a nameserver problem -- pinging outside sites by their IP addresses doesn't work either. I have another laptop next to this one, also running Kubuntu 12.10. On the one that can't connect, arp produces no output. On the other one, it produces 192.168.0.1 ether 00:23:69:fa:ce:ae C wlan0 On the working machine, the output of netstat starts with some tcp entries. On the nonworking one, those entries are absent. I asked this question on the Ubuntu forum but haven't gotten any answers there. One further complication: since the troublesome machine has no outside connection, it's extremely difficult to download anything to it. For what it's worth, "ping 8.8.8.8" produces "connect: Network is unreachable". Update: after a lot of fiddling, I have my external world back. I don't know what the key action was, but the first indication of progress was that "ping 8.8.8.8" worked. At that point I still didn't have a working nameserver, so external URLs didn't work. But I did this (based on an online post, of course): sudo dpkg-reconfigure resolvconf and answered Yes to all prompts. That did the trick!! Apparently my problem was unique, or close to it, since I couldn't find any online references to it: local net working, remote net not working, including explicit IP addresses. So I suppose that if no one else has this problem, no one cares about the solution!!

• Will I be able to get programming interviews at good software companies with a non-CS degree?

  - by friend

  I'll be graduating in a year, but I'll have a degree in Economics. I'm pretty much done with my Economics coursework, and by the time next year comes around I will have devoted 1.5 years to learning CS. I will have almost finished the requirements to graduate with a degree in CS, but unfortunately my school requires a science series that would add another 6-9 months of study if I were to try and get the degree (not to mention a max unit cap). I have or will have taken: Objected Oriented Programming Discrete Math Data structures Calculus through multivariable (doubt this matters at all) Linear Algebra (same) Computer Organization Operating Systems Computational Statistics (many data mining projects in R) Parallel Programming Programming Languages Databases Algorithms Compilers Artificial Intelligence I've done well in the ones I've taken, and I hope to do well in the rest, but will that matter if I can't say to the HR people that I have a CS degree? I'd be happy to get an internship at first too, so should I just apply as if I'm an intern and not looking for fulltime, and then try and parlay that into something? Sidenote if you have time -- Is a computer networks or theory of computation class important? Would it be worth taking either of those in lieu of a class on my list? edit -- I know this isn't AskReddit or College Confidential; I know there will be some outrage at posting a question like this. I'm merely looking for insight into a situation that I've been struggling with, and I think this is the absolute best place to find an answer to this question. Thanks.

• two thoughts about career excellence

  - by john.rose

  I love Dickens, warts and all. Sometimes he is sententious, and (like the mediocre modern I am) at such points I am willing to listen non-ironically. This bit here struck me hard enough to stop and write it down: I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for. It is Woodcourt's kind. (John Jarndyce to Esther Summerson, Bleak House, ch. 60) Woodcourt is, of course, one of the heroes of the story. It is a heroism that is attractive to me. Here is a similar idea, from the Screwtape Letters. In the satirically inverted logic of that book, the “Enemy” is God, the enemy of the devils but the author of good: The Enemy wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the, fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another. (C.S. Lewis, Screwtape Letters, ch. 14) Though I will be happy with a good Bazaar, I also dream of Cathedrals. Put whatever name you like on it, as long as I get some part in the fun of building a good one.

• How do I configure an Intel HD Graphics 4000?

  - by derabbink

  First off, please note that last night I already posted this question to a launchpad mailing list, so this could be considered a cross post. However, I think this is a better place to ask the same question The question: How can I configure my Ubuntu 12.04, with upgraded kernel (3.6), to use the Intel HD Graphics 4000 adapter? (Intel HD 4000 is the standard of 3rd gen Intel Core i7 (Ivy Bridge) graphics adapter) Some output: $ glxinfo name of display: :0 X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12 $ cat /etc/X11/xorg.conf this is probably the farthest from what it should be Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Module" Load "glx" EndSection $ lspci I only listed the line I think are relevant.

• Rendering 8 bit graphics

  - by Matjaz Muhic

  I have a strong programming background just not from game development. I only made some pong and snake in high school and I did some OpenGL in college. I want to make my own game engine. Nothing fancy just a simple 2D game engine. But because I'm kinda old school and feeling retro. I want graphics to look like old 8 bit games (megaman, contra, super mario, ...). So how were the old games made back then? I want the simplest approach. Were they also using assets (images) like newer engines now do? How do you achieve this kind of rendering using OpenGL? Keep in mind. Simplest solution. I want to know how it was made back then and how I can replicate that. Doesn't even have to be OpenGL. I can draw on window canvas. I do want to make it from scratch basically.

• How do I implement deceleration for the player character?

  - by tesselode

  Using delta time with addition and subtraction is easy. player.speed += 100 * dt However, multiplication and division complicate things a bit. For example, let's say I want the player to double his speed every second. player.speed = player.speed * 2 * dt I can't do this because it'll slow down the player (unless delta time is really high). Division is the same way, except it'll speed things way up. How can I handle multiplication and division with delta time? Edit: it looks like my question has confused everyone. I really just wanted to be able to implement deceleration without this horrible mass of code: else if speed > 0 then speed = speed - 20 * dt if speed < 0 then speed = 0 end end if speed < 0 then speed = speed + 20 * dt if speed > 0 then speed = 0 end end end Because that's way bigger than it needs to be. So far a better solution seems to be: speed = speed - speed * whatever_number * dt

• HTML5 - Does it have the power to handle a large 2D game with a huge world?

  - by user15858

  I have been using XNA game studio, but due to private reasons (as well as the ability to publish anywhere & my heavy interest in isogenic engine), I would like to switch to HTML5. However, I have very high 2D graphic demands for my game. The game itself will have a HDD size of anywhere between 6GB (min) to 12GB (max) which would be a full game deployed offline. The size of the images aren't significantly large, so streaming would be entirely possible if only those assets required were streamed as needed. The game has a massive file size because of the sheer amount of content. For some images or spritesheets, they would be quite massive. (ex. a very large Dragon, which if animated in a spritesheet would be split into two 4096x4096 sheets or one 8192x8192 sheet). Most assets would be very small, and about 7MB for a full character with 15 animations in every direction (all animations not required immediately) so in the size of a few hundred KB to download before the game loads. My question, however, is if the graphical power of HTML5 is enough to animate several characters on screen at once, when it flips through frames quite rapidly. All my sprites have about 25 frames per animation, 5 directions (a spritesheet for each direction & animation), and run at 30fps. Upon changing direction, animation, or a new character entering, spritesheets would change and be constantly loading/unloading. If I pack all directions in a single sheet, it would be about 2048x2048 per sheet. Most frameworks have no problem with this, but I am afraid from what I read that HTML5's graphical capabilities will limit me. Since it takes significant time simply to animate characters in any language, I'd like a quick answer.

• Writing generic code when your target is a C compiler

  - by enobayram

  I need to write some algorithms for a PIC micro controller. AFAIK, the official tools support either assembler or a subset of C. My goal is to write the algorithms in a generic and reusable way without losing any runtime or memory performance. And if possible, I would like to do this without increasing the development time much and compromising the readability and maintainability much either. What I mean by generic and reusable is that I don't want to commit to types, array sizes, number of bits in a bit field etc. All these specifications, IMHO, point to C++ templates, but there's no compiler for it for my target. C macro metaprogramming is another option, but, again my opinion, that greatly reduces readability and increases development time. I believe what I'm looking for is a decent C++ to C translator, but I'd like to hear anything else that satisfies the above requirements. Maybe a translator from another high-level language to C that produces very efficient code, maybe something else. Please note that I have nothing against C, I just wish templates were available in it.

• Audio not working in 12.10

  - by frampy

  I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this? Edit: I've been reading the sound troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting It looks like Ubuntu is finding my audio device correctly. mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp.

• One of my VMs went boom using Virtual Box and how it got fixed

  - by Enrique Lima

  I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

• Approach to Authenticate Clients to TCP Server

  - by dab

  I'm writing a Server/Client application where clients will connect to the server. What I want to do, is make sure that the client connecting to the server is actually using my protocol and I can "trust" the data being sent from the client to the server. What I thought about doing is creating a sort of hash on the client's machine that follows a particular algorithm. What I did in a previous version was took their IP address, the client version, and a few other attributes of the client and sent it as a calculated hash to the server, who then took their IP, and the version of the protocol the client claimed to be using, and calculated that number to see if they matched. This works ok until you get clients that connect from within a router environment where their internal IP is different from their external IP. My fix for this was to pass the client's internal IP used to calculate this hash with the authentication protocol. My fear is this approach is not secure enough. Since I'm passing the data used to create the "auth hash". Here's an example of what I'm talking about: Client IP: 192.168.1.10, Version: 2.4.5.2 hash = 2*4*5*1 * (1+9+2) * (1+6+8) * (1) * (1+0) Client Connects to Server client sends: auth hash ip version Server calculates that info, and accepts or denies the hash. Before I go and come up with another algorithm to prove a client can provide data a server (or use this existing algorithm), I was wondering if there are any existing, proven, and secure systems out there for generating a hash that both sides can generate with general knowledge. The server won't know about the client until the very first connection is established. The protocol's intent is to manage a network of clients who will be contributing data to the server periodically. New clients will be added simply by connecting the client to the server and "registering" with the server. So a client connects to the server for the first time, and registers their info (mac address or some other kind of unique computer identifier), then when they connect again, the server will recognize that client as a previous person and associate them with their data in the database.

• How to encourage domain experts familiar only with C into a C++ opensource project [closed]

  - by paperjam

  Possible Duplicate: How to persuade C fanatics to work on my C++ open source project? I am launching an open-source project into a space where a lot of development is done Linux-kernel-style, i.e. C-language with a low-level mindset. My project is broad and complex and uses aspects of the C++ language and libraries, including the Boost library to best effect for simple, slightly syntactically sweetened, elegant and well structured high level code. We are using C++ templates too to avoid duplication of code and for static polymorphism in code specialisation for performance. Many of the experts in this field are well used to pure C-language projects. How can I persuade them to contribute to my idiomatic C++ based project? I have no objection to C-language subcomponents or the use of a C-like subset for parts of the project so that might be part of the answer. This is a rewritten and retagged rehash of my previous question that was closed. Apologies to those who read and answered for it not being constructive. I hope this new question is viewed as constructive. Please note that this is not a language advocacy question and please keep answers in that spirit.

• Work @ Java shop. Tasked to redo intranet. I only know PHP - CTO says use that; Ops Says no - we have JSP, use that - Thoughts?

  - by Mackysback

  So I work as a project manager and was given the opportunity to redo the intranet and Internet site... I'd love to , great addition to my resume. However.... I am not familiar with java nor JSP... I am fairly proficient with PHP and MySQL ... Also my intention was to use a CMS that I have experience with, wordpress, drupal or joomla... The site would be very simple so I was thinking wordpress would be fine for this. I told management that I would need it to run on PHP and they gave me their blessing... Now the disconnect bw it and management ... I spoke with ops and they told me that we have java and JSP for that purpose although the IT guy did say "oh but I do know that php and mysql are gaining popularity" That said ... I do not understand much as far as systems architecture... We do self host and run websphere with IIS and jboss with tomcat. Any advice or suggestions? Thanks ! Is my request that unfeasible?

• Feedback on meeting of the MSCC - 20.07.2013

  Impression of our meetup on 20.07.2013 Low quantity but high quality! Meetup summary: Quick introduction to ?MSCC? and interesting topics in general, especially for freshman from/at university. It also seems that the open concept of OUYA (Android-based gaming console) got some attention and hopefully new fans. More info is available online: http://www.ouya.tv/ Design contest The design contest is still going on... There's currently only one submission. Come on, you web & graphic designers in Mauritius - SHOW YOUR WORKAny draft will be published over here: MSCC Design Contest - https://www.facebook.com/media/set/?set=a.200036533488751.1073741829.181737551985316&type=3 Goodies give-away And the first 2 one-month subscriptions for Pluralsight have been well received by attendees, too. Unfortunately, we didn't have any free WiFi at Talking Drums - so, we might have to consider another location for the next meetup. Change of schedule As we spoke about the advantages of gathering during the weekend, we worked out a schedule that could be applied to future meetups of the MSCC. I'm going to address this tomorrow during our regular meetings on Wednesday to see about the response of other members, too.

• Role based access to resources for a RESTful service

  - by mutex

  I'm still wrapping my head around REST, but I wonder if someone can help with any suggestions or approaches to role based access control for a RESTful service, particularly from the point of view of securing the data and how the URLs might look. It's probably best to consider an example: Say I have a REST service for Customers, and want to split the users of this REST service into Admin, Editor and Reader roles: Admins can change all attributes of a Customer resource Editors can change only some Readers can only view them. Access control rights are assigned to the Customers entities individually. So for example a user of the service might have admin rights to Customers 1,2 and 3 but Editor access to 4,5 and Reader access to 7,8,9. Now consider the user calling the service. What is a good way to seperate the list of Customers for the current User? GET /Customer - this might get a list of all customers that the current user has Admin\Editor\Reader access to. But then on each Customer the consumer would need an indication of what role they have. Or would it be "better" having something like GET /Customer/Admin - return all customers the current user has Admin access to. Just looking for some high level pointers or reading on a decent way to secure\filter the resources based on roles of the current user.

• NFS mount of /var/www to OS X

  - by ploughguy

  I have spent 2 hours trying to create an NFS mount from my Ubuntu 10.04 LTS server to my OS X desktop system. Objective: three way file compare between the code base on the Mac, the development system on the local Linux test system, and the hosted website. The hosted service uses cpanel so I can mount a webdisk - easy as pie - took 10 seconds. The local Ubuntu box, on the other hand - nothing but pain and frustration. Here is what I have tried: In File Browser, navigate to /var/www/site and right-click. Select share this folder. Enter sharename wwwsite and a comment. Click button "Create Share". Message says - you can only share file systems you own. There is a message on how to fix this, but the killer is that this is sharing by SMB. It will change the LFs to CR-LFs which will affect the file comparison. So forget this option. In a terminal window, run shares-admin (I have not been able to convince it to give me the "Shared Folders" option in the System Administration window - Maybe it is somewhere else in the menu, but I cannot find it) define an NFS export. Enter the path /var/www/site, select NFS enter the ip address of the iMac and save. On the mac, try to mount the file system using the usual methods - finder, command line "mount" command - not found. Nothing. Tried restarting the linux box in case there is a daemon that needs restarting - nothing. So I have run out of stuff to do. I have tried searching the documentation - it is pretty basic. The man page documentation is as opaque as ever. Please, oh please, will someone help me to get this @38&@^# thing to work! Thanks for reading this far... PG.

• How can one find software development work that involves directly the final end user?

  - by RJa

  I've worked in software development for 15 years and, while there have been signficant personal achievements and a lot of experience, I've always felt detached from the man/woman-on-the-street, the every day person, how it affects their lives, in a number of ways: the technologies: embedded software, hidden away, stuff not seen by the everyday person. Or process technology supporting manufactured products the size of the systems, meaning many jobs, divided up, work is abstract, not one person can see the whole picture the organisations: large, with departments dealing with different areas, the software, the hardware, the marketing, the sales, the customer support the locations and hours: out-of-town business parks away from the rest of society, fixed locations, inflexible: 9-5 everyday This to me seems typical of the companies I worked for and see elsewhere. Granted, there are positives such as the technology itself and usually being among high calibre co-workers, but the above points frustrate me about the industry because they detach the work from its meaning. How can one: change these things in an existing job, or compensate for them? find other work that avoids these and connects with the final end user? Job designs tend to focus on the job content and technical requirements rather than how the job aims to fulfil end user needs, is meaningful.

• Dell Inspiron7520 and ubntu 12.04 issues

  - by user91358

  I have a DELL Inspiron 7520 in the highest configuration: 3rd Generation Intel® Core™ i7-3612QM processor (6M Cache, up to 3.1 GHz) 15.6" Full High Definition (1080p) LED Display 8GB3 Dual Channel DDR3 SDRAM at 1600MHz 1TB 5400RPM SATA HDD + 32GB mSATA SSD w/Intel Smart Response Blu-ray Disc (BD) Combo (Reads BD and Writes to DVD/CD) AMD Radeon™ HD 7730M 2GB 6.09 lbs and I have installed Ubuntu 12.04 few days ago and I'm facing some issues: 1) sometimes the whole ntb freezes and I have to hold power button for 5 secs to shut it down. I think it is something with VGA and connected external monitor. I have read somewhere that it is already a reported bug, but what I am not sure about that it is doing sporadically. Sometimes it freezes right after I log in, sometime I ran few hours and then it freezes. I am using those proprietary drivers but I wasn't been able to install those with updates. 2) the next issue is the fan is quite noisy even when the ntb is almost Idle. (max 10% CPU usage). Can you recommend me some software which could do this power management to lower the noise? I have tried CPU frequency scaling indicator, but it seems that it has not any effects. 3) and issue no. 3: when I want to log out, restart or shutdown using the menu in upper right corner the upper and left trays disappear, but programs are still running and they won't close to complete log out or shutting down the OS. When I use the CLI command, it works fine. Thanks for any help you can provide.

• Setting up a network between a host and guest virtual machine

  - by anonymous

  (I'm running ubuntu server 12.04 on virtual box) I'm trying to transfer a file (scp) from my laptop to one of the directories of a virtual machine. I tried sharing folders, but that failed. I'm a bit of a networking newbie. I've looked at like 20-30 pages. Here's one: http://www.howtoforge.com/moving-files-between-linux-systems-with-scp I followed those steps exactly. My problem is that when I try using scp, it just hangs. I'm also not sure which network interface to configure (eth0, eth1?) in the guest OS. Another (significant?) detail is that the inet address of eth0 is 10.0.2.15 instead of something like 192.168.x.y. I've enabled the bridge adapter and the host-only adapter. Both the laptop and guest VM have openssh-server installed. I'm not sure what to do at this point. Is there a better place to ask about this?
