• Can I use MSBuild to build old VS6 C++ projects?

  - by awe

  I have a build computer where Visual Studio not installed, only MSbuild which can build VS2008 projcets without having any Visual Studio installed. I wonder whether it is possible to use MSbuild with VC++ 6.0 project files, although I am thinking this could not be possible. In the past I have used it with a VS2008 solution file for C++, but not for building C++ 6.0 dsw file. For Vb6 we have an extension package for Msbuild (MSBuild.ExtensionPack.VisualStudio.VB6). Is anything similar available for C++ 6.0 projects? An alternative could be if there are lightweight build tools that can built VC6++ .dsw files without having to install Visual Studio 6.0 ?

• Java Cryptography Extension

  - by Adam Tannon

  I was told that in order to support AES256 encryption inside my Java app that I would need the JCE with Unlimited Strength Jurisdiction Policy Files. I downloaded this from Oracle and unzipped it and I'm only seeing 2 JARs: local_policy.jar; and US_export_polic.jar I just want to confirm I'm not missing anything here! My understanding (after reading the README.txt) is that I just drop these two into my <JAVA_HOME>/lib/security/ directory and they should be installed. By the names of these JARs I have to assume that its not the Java Crypto API that cannot handle AES256, but it's in fact a legal issue, perhaps? And that these two JARs basically tell the JRE "yes, it's legally-acceptable to run this level of crypto (AES256)." Am I correct or off-base?

• Is it necessary to create a database with as few tables as possible

  - by Shaheer

  Should we create a database structure with a minimum number of tables? Should it be designed in a way that everything stays in one place or is it okay to have more tables? Will it in anyway affect anything? I am asking this question because a friend of mine modified some database structure in mediaWiki. In the end, instead of 20 tables he was using only 8, and it took him 8 months to do that (it was his college assignment). EDIT I am concluding the answer as: size of the tables does NOT matter, until the case is exceptional; in which case the denormalization may help. Thanks to everyone for the answers.

• How can I install Ubuntu Saucy Server with BTRFS?

  - by Walter Souto

  So, a week ago I installed the latest beta version of Ubuntu Saucy Server in a MacMini using BTRFS as only partition to mount "/" on it (I know it's not recommended to do this, but it's not the point here) with no problems et al. Everything went just "naturally"... Now with the released image of 13.10 server, I just can't get any BTRFS partition done from installer. I'm getting a "Can't create filesystem" error whenever I try to create any BTRFS partition, like the 13.10 server final installer can't handle format BTRFS partitions... Am I doing something wrong? Or it's a bug in the installer? Is there anything that I can do to workaround this and get my BTRFS partition set on installation, or I'll need to work this after the installation. I can just leave some space left and create a btrfs partition later on, with Saucy already installed and proceed to use to LXC (which is my solo purpose to have btrfs), but anyway, why installer can't do btrfs anymore?

• HTML5 mobile game development vs. native game apps

  - by Vic Szpilman

  What is the current state of game engines, frameworks, libraries and conversions related to the HTML5 set of technologies (including CSS3 and JavaScript libraries such as RaphaelJS, Impact, gameQuery); and how does the best of that compare with developing a native app (especially for iOS and Android)? Especially in terms of performance, visuals and getting that "native feel". Thoughts on solutions such as Appcelerator and Corona SDK are also appreciated. In regards to Unity3D, is it possible to develop in it and still have the game be playable on a browser (such as current releases of Chrome or Firefox, at least) without any dependencies or having the user install anything (no unity web player). What I'm looking for is how to develop in web standards as to reach the maximum number of platforms (including outside mobile) while still retaining a native experience for mobile without having to implement the game anew for iOS and Android.

• Can not remove cube in UDK

  - by user32228

  For some reason, I can't move or remove an 'invisible' cube which is on my map. I searched on Google to find a solution but somehow I still can't remove it. The cube looks like this: http://screencloud.net/v/uNyz In Brush Wireframe: http://screencloud.net/v/3C0c In Wireframe: screencloud.net/v/oGBj As you can see, I want to delete the brown cube. Selecting it and pressing the DEL button won't do anything. So, how do you delete the brown cube? EDIT: Seriously, I wrote this post a few minutes ago and I found the solution. However, I still don't know how to delete the brown cube.

• Battery management doesn't recognize removal of power supply

  - by Jason

  I have a Lenovo Y460p running Ubuntu 12.04 (64-bit). The battery does charge normally, but unplugging the power supply only very briefly shows the correct battery indicator. After about 1 second, it reverts to the charging indicator. If the power supply is connected the power statistics show: "Supply Yes" "Online Yes" If it is not connected it shows: "Supply Yes" "Online No" My problem is almost exactly like the one in this post: Ubuntu 11.10 power management does not recognize removal of power supply The only exception is that my system does not dual-boot with Windows. This is Ubuntu only. The computer in the other post is a Lenovo as well; not sure if that has anything to do with it. Any help would be greatly appreciated. Thanks.

• Why there is perception that VB.NET is good for small to medium size application and not for enterprise class project?

  - by Gens

  I love VB.NET very much. Coding VB.NET with Visual Studio is just like typing messages. Smooth, fast and simple. Any error will be notified instantly. The OO capability of VB.NET is good enough. But often in any .Net languages discussion, there is perception that VB.NET is good for small to medium size application and not for large scale project? Why there is such perception? Or am I missing anything regarding to VB.NET?

• Designing A 2-Way SSL RESTful API

  - by Mithir

  I am starting to develop a WCF API, which should serve some specific clients. We don't know which devices will be using the API so I thought that using a RESTful API will be the most flexible choice. All devices using the API would be authenticated using an SSL certificate (client side certificate), and our API will have a certificate as well ( so its a 2 Way SSL) I was reading this question over SO, and I saw the answers about authentication using Basic-HTTP or OAuth, but I was thinking that in my case these are not needed, I can already trust the client because it possesses the client-side certificate. Is this design ok? Am I missing anything? Maybe there's a better way of doing this?

• alsHigh CPU load - Ubuntu 14.04

  - by watt

  I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

• Random Map Generation in Java

  - by Thomas Owers

  I'm starting/started a 2D tilemap RPG game in Java and I want to implement random map generation. I have a list of different tiles, (dirt/sand/stone/grass/gravel etc) along with water tiles and path tiles, the problem I have is that I have no idea where to start on generating a map randomly. It would need to have terrain sections (Like a part of it will be sand, part dirt etc) Similar to how Minecraft is where you have different biomes and they seamlessly transform into each other. Lastly I would also need to add random paths into this as well going in different directions all over the map. I'm not asking anyone to write me all the code or anything, just piont me into the right direction please. tl;dr - Generate a tile map with biomes, paths and make sure the biomes seamlessly go into each other. Any help would be much appreciated! :) Thank you.

• What is a good site to use for scheduling 20+ developers and 10 projects? (resource planning) [closed]

  - by b-ryce

  I have around 20 developers and 10 or so active projects. Then I get asked if my team can take on more work, and who is going to free up when. Currently we are using a spreadsheet to keep track :( I've been digging around for a few hours and haven't found anything that meets my requirements, which are: Web based Schedule a developer's time over a period of days/weeks/months Be able to see at a glance which developer has extra capacity Quickly see when the group could take on another large project I don't mind paying for the software (It does NOT need to be free) Two projects which look close are http://www.ganttic.com/tour and http://resourceguruapp.com/ What else are people using? Anyone have the perfect solution

• Why was Python's popularity so sudden? [closed]

  - by Eric Wilson

  Python first appeared in 1991, but it was somewhat unknown until 2004, if the TIOBE rankings quantify anything meaningful. What happened? What caused the interest in this 13 year old language to go through the roof? Is there a reason that Python wasn't considered a real competitor to Perl in its first decade of existence? Is there a reason that Python didn't continue in relative obscurity for another ten years? I personally think that Python is a very nice language, and I'm glad that I'm not the only one. But it doesn't have corporate backing or a killer feature that would explain a sudden rise to relevance. Does anyone know the story?

• Case Class naming convention

  - by KChaloux

  In my recent adventures in Scala, I've found case classes to be a really nice alternative to enums when I need to include a bit of logic or several values with them. I often find myself writing structures that look like this, however: object Foo{ case class Foo(name: String, value: Int, other: Double) val BAR = Foo("bar", 1, 1.0) val BAZ = Foo("baz", 2, 1.5) val QUUX = Foo("quux", 3, 1.75) } I'm primarily worried here about the naming of the object and the case class. Since they're the same thing, I end up with Foo.Foo to get to the inner class. Would it be wise to name the case class something along the lines of FooCase instead? I'm not sure if the potential ambiguity might mess with the type system if I have to do anything with subtypes or inheritance.

• install Cirrus Logic cs46xx (audio card) drivers

  - by Aikanáro

  I have two sounds cards, one is the on-board (it's VIA) the other is Cirrus Logic cs46xx. This is what lspci shows me: 04:04.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] (rev 01) It only show the cirrus logic, cause I disable the VIA card through BIOS. This page: http://es.driverscollection.com/?file_id=13152 gives me instructions to install it, but I can follow them because the folders indicates in the page do not matches with the ones that I see in my system. The alsa page: http://alsa-project.org/main/index.php/Matrix:Module-cs46xx, also give me instructions, but I don't understand it. For example, they say: type in a terminal: ./configure but don't say in what directory. I think that isn't instructions for begginers... Right now I can't heard anything. I decide to disable the VIA audio card, cause I've read they don't get along with linux, although i use the integrate VIA video card. I have ubuntu 11.10

• Bastion unexpectedly exits when I move my cursor

  - by user69358

  I downloaded the Humble Indie Bundle V, mostly because my friend told me about how great Bastion was. When I first installed it, I was getting the seemingly common "black screen" error that most people got (fixed that half with this http://ubuntuforums.org/showthread.php?p=11992661). But I also have an error where every time I move my cursor, in any direction, any amount, the game closes instantly. I can use the keyboard no problem, but without fail, every time I move my mouse, it crashes. Does anyone know what might be causing this? Has anyone encountered anything like this before? I am worried it may be a hardware issue, but hoping someone might be able to help me out. I'm running Ubuntu 12.04 on a Dell Studio 1558. Graphics card is the stock Intel graphics card, running on 4 GB of RAM.

• Modify actions when battery is critically low?

  - by Bjarke Freund-Hansen

  I am running ubuntu (not xubuntu!) and am using xfce4 on my laptop. When my laptop battery is critically low, ubuntu/xfce4 performs some action (perhaps hibernate?) which causes my laptop to shut down. However when I start it again, it never comes up. I don't even get BIOS or anything on the screen, it is completely black. The only way to get it back up is to take it apart, remove the internal cmos battery as well as the main battery, wait a few minutes, and put it back together. Obeviously this is not optimal. How do I disable all actions when the battery is critically low? I would rather have it run out of power, than ending up in this error condition. Thanks in advance. :)

• Detecting End of Animation

  - by Will

  So I am making a death animation for a game. enemy1 is a UIImageView, and what I'm doing is when an integer is less than or equal to zero, it calls this deathAnimation which only happens once. What I want to do is use a CGPointMake right when the animation is finished being called. Note that before the deathAnimation is called, there is another animation that is constantly being called 30 times a second. I'm not using anything like cocos2d. if (enemy1health <= 0) { [self slime1DeathAnimation]; //How can i detect the end of this animation } This is how the animation is done -(void)slime1DeathAnimation{ enemy1.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Slime Death 1.png"], [UIImage imageNamed:@"Slime Death 2.png"], [UIImage imageNamed:@"Slime Death 3.png"], [UIImage imageNamed:@"Slime Death 4.png"], [UIImage imageNamed:@"Slime Death 5.png"], nil]; enemy1.animationDuration = 0.5; enemy1.animationRepeatCount = 1; [enemy1 startAnimating]; } If you need more code just ask

• How do I rebuild a corrupt dpkg status file?

  - by Ramón

  Whenever I type sudo apt-get remove and then press the Tab key for auto-completion I get the following message: grep-status: /var/lib/dpkg/status:15945: expected a colon. I don't see anything especially strange at line 15945 in the status file. It's a dot character in the description field of a mono library package and inserting a colon did not help. Removing the line containing the dot did not work either. Overwriting the file with status-old resulted in the same message. Is there some way to rebuild the status file?

• Screen Corruption in half the screen only

  - by Guy DAmico

  About 50% of the my NATTY desktop screen is corrupted. Once that happens I can re-boot as many times as I want but the problem continues. If I logout and then into WINDOWS for a day I may be successful and boot UBUNTU with a good screen. The desktop is formatted correctly, there's no pixelation, rather there is a fine grained white crosshatch pattern covering the entire screen. If I open any application the screen corruption worsens eventually to the point I can no longer make out anything. I ran ram memory test w/o any errors. I have no display issues when running WINDOWS 7. Any ideas. My computer is a Dual Boot stock DELL 5150 w/3gig of ram an on board video.

• How do I change the default .htm file icon?

  - by Michael Clayton

  I really enjoy the look of UBUNTU. The only thing that I want to change is the default icon used for .html (.htm) files. I want to use the icon /usr/lib/firefox/browser/icons/mozicon128.png instead. I do not want to change any other visual element. Is there a practical way to accomplish this small change? edit: @Mitch, I've used assogiate in the past and although I was able to change the icon used for .mht files, I could not get it to change the .htm icon. @Anwar Shah, thanks for the information. I wish that it would work for me. Running 13.10 x86, after I do the copy of the icons, in the folders are a bunch of links to .svg files not actual graphics files. It does not appear that the second copy actually does anything on my system.

• When to mark a user story as done in scrum?

  - by Saeed Neamati

  There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?
