• Obtaining In game Warcraft III data to program standalone AI

  - by Slav

  I am implementing common purpose behavioral algorithm and would like to test it under my lovely Warcraft III game and watch how it will fight against real players. The problem is how to obtain information about in game state (units, structures, environment, etc. ). Algorithm needs access to hard drive and possibly distributed computing, that's why JASS (WC3 Editor language) usage doesn't solve the issue. Direct 3D hooking is an approach, but it wasn't done for WC3 yet and significant drawback is inability to watch online at how AI performs since it uses the viewport to issue commands. How in game data can be obtained to a different process in a fastest and easiest way? Thank you.

• C++ Library API Design

  - by johannes

  I'm looking for a good resource for learning about good API design for C++ libraries, looking at shared objects/dlls etc. There are many resources on writing nice APIs, nice classes, templates and so on at source level, but barely anything about putting things together in shared libs and executables. Books like Large-Scale C++ Software Design by John Lakos are interesting but massively outdated. What I'm looking for is advice i.e. on handling templates. With templates in my API I often end up with library code in my executable (or other library) so if I fix a bug in there I can't simply roll out the new library but have to recompile and redistribute all clients of that code. (and yes, I know some solutions like trying to instantiate at least the most common versions inside the library etc.) I'm also looking for other caveats and things to mind for keeping binary compatibility while working on C++ libraries. Is there a good website or book on such things?

• Worthwhile to upgrade my Ruby Pickaxe book?

  - by ewindisch

  I have Programming Ruby, The Pragmatic Programmers' Guide, Second Edition which covers Ruby 1.8. It has been several years since I have programmed in Ruby, but I'd like to refresh my memory and bring my knowledge current. With most programming languages, I've found that I can skip books that only concern a single version bump. Yet, Ruby is a young language and I understand there may have been significant changes in 1.9. Although I already have the second edition, is it worthwhile to buy the third edition for Ruby 1.9? Are the differences that vast, or will it be simple enough to catch up to 1.9 with the online docs?

• Securing data inside Azure SQL? Any good libraries or DIY?

  - by Sid

  Azure SQL doesn't support many of the encryption features found in SQL Server (Table and Column encryption). We need to store some sensitive information that needs to be encrypted and we've rolled our own using AesCryptoServiceProvider to encrypt/decrypt data to/from the database. This solves the immediate issue (no cleartext in db) but poses other problems like Key rotation (we have to roll our own code for this, walking through the db converting old cipher text into new cipher text) metadata mapping of which tables and which columns are encrypted. This is simple with it's a few but quickly gets out of hand ... So are there any libraries out there that do this well? Any other resources or design patterns I can be pointed to?

• Procedural world generation oriented on gameplay features

  - by Richard Fabian

  In large procedural landscape games, the land seems dull, but that's probably because the real world is largely dull, with only limited places where the scenery is dramatic or tactical. Looking at world generation from this point of view, a landscape generator for a game needs to not follow the rules of landscaping, but instead some rules married to the expectations of the gamer. For example, there could be a choke point / route generator that creates hills ravines, rivers and mountains between cities, rather than cities plotted on the land based on the resources or conditions generated by the mountains and rainfall patterns. Is there any existing work being done like this? Start with cities or population centres and then add in terrain afterwards?

• Bzr Eclipse Plugin not configurable

  - by Ubuntourist

  I'm relatively new to Eclipse. I'm currently running bzr 2.2.1 and Eclipse 3.5.2 (Galileo). Following the directions at: http://wiki.bazaar.canonical.com/BzrEclipse/Installation I get to the point where it tells me the plugin has been successfully installed, but when I attempt to configure it at Window -- Preferences -- Team -- Bazaar, there's no "Bazaar" there. Team shows CVS, File Contents, Ignored Resources and Models. (Nothing useful under CVS.) Nothing in ~/workspace/.metadata/.log about bzr either. I've uninstalled and reinstalled the plugin a few times, to no avail. Is there a more thorough way to uninstall that plugin without removing everything else that's been installed? Is there somewhere else I should be looking for the source of trouble? I didn't see anything promising on Launchpad, but may not have looked deep enough.

• Gracefully terminate a request based service on server

  - by Jatin

  In our web application, for each http-request there is a lot of computation that happens on back end. Output can vary from 10 sec - 1 Hour. In the mean time when it is computed, "Waiting.." is shown on the website for the respective user. But it so happens, that a user might cut down the service in between. So what all can be done on the back end so that the computation can be stopped in between to save resources? What different tactics can be applied here? And if better (instead of killing the thread directly), then a graceful termination policy should make wonders.

• RAM Cache always full

  - by Tobias

  I have 6GB RAM, i5 2.4GHZ Processor running Ubuntu 11.10. When streaming online or opening several tabs in Chromium I soon have 4GB Memory in the cache. And this makes my Notebook slow. When streaming a video, after a few minutes it really slows down and stumbles/jerks. I partitioned my HD so that I have 8GB swap. What could the problem be? How can I solve this? P.s: initially I had 4gb and recently upgraded to 6GB, but I did not experience a significant change. P.P.S: if I enter "free -g" in the terminal this is the result: total used free shared buffers cached Mem: 5 2 3 0 0 0 -/+ buffers/cache: 1 4 Swap: 8 0 8

• Copy machine security issues.

  - by David Nudelman

  I am involved on a project to talk to communities about the risks of posting online content is social networks. But this time I was really impressed how far security concerns can go. This video from CBS news talks about security risks related to corporate fax/printers and scanners. It was very clear that when they got the machines they selected the machines by previous owner and they were not random machines, but still, I will never scan from my company machine again. I guess the price of multifunction printers will go up if this video goes viral. Regards, David Nudelman

• Java 7 Adoption at 79%

  - by Henrik Stahl

  According to a recent blog post from the cloud hosting company Jelastic, Java 7 adoption on their platform is now at 79%. While this is a single data point and should not be read too broadly, it does match other indicators we have that Java 7 is picking up, such as uptake among Oracle middleware customers, download statistics and online activity. The spike in adoption in April coincided with the release of JDK 7 Update 4. This is in line with our expectations since that release added Mac OS X support as well as java.com moving to Java 7 as the default download for end-users; two events that marked the maturity of Java 7 to the community. Since the original release of Java 7, Oracle has shipped 7 update releases, added ports to Mac OSX and Linux/ARM and expanded JavaFX to all common desktop platforms.

• The Basics of Project Management / Software Development

  - by Sam

  It suddenly struck me today that I have never developed any large application or worked with a team of programmers, and so am missing out a lot - both in terms of technical knowledge and the social-fun part of it. And I would like to rectify that - an idea is to start an open source group by training college students (for no charge) and developing some open source application with them. Please give me some basic advice on the whole process of how to (1) plan and (2) manage projects in a team. What new skill sets would you recommend? (I have read joel on software and 37 Signals, and got many insightful tips from them. But I'd like a little more technical knowledge ...) Background (freelancer, past 4+ years) - Computer engineer graphic / web designer online marketing moved on to programming in PHP, Perl, Python did Oracle DBA OCP training to understand DB's current self-assigned title - web application developer.

• Doing an SNES Mode 7 (affine transform) effect in pygame

  - by 2D_Guy

  Is there such a thing as a short answer on how to do a Mode 7 / mario kart type effect in pygame? I have googled extensively, all the docs I can come up with are dozens of pages in other languages (asm, c) with lots of strange-looking equations and such. Ideally, I would like to find something explained more in English than in mathematical terms. I can use PIL or pygame to manipulate the image/texture, or whatever else is necessary. I would really like to achieve a mode 7 effect in pygame, but I seem close to my wit's end. Help would be greatly appreciated. Any and all resources or explanations you can provide would be fantastic, even if they're not as simple as I'd like them to be. If I can figure it out, I'll write a definitive how to do mode 7 for newbies page. edit: mode 7 doc: http://www.coranac.com/tonc/text/mode7.htm

• C++ - Constructor or Initialize Method to Startup

  - by Bob Fincheimer

  I want to determine when to do non-trivial initialization of a class. I see two times to do initialization: constructor and other method. I want to figure out when to use each. Choice 1: Constructor does initialization MyClass::MyClass(Data const& data) : m_data() { // does non-trivial initialization here } MyClass::~MyClass() { // cleans up here } Choice 2: Defer initialization to an initialize method MyClass::MyClass() : m_data() {} MyClass::Initialize(Data const& data) { // does non-trivial initialization here } MyClass::~MyClass() { // cleans up here } So to try and remove any subjectivity I want to figure out which is better in a couple of situations: Class that encapsulates a resource (window/font/some sort of handle) Class that composites resources to do something (a control/domain object) Data structure classes (tree/list/etc.) [Anything else you can think of] Things to analyze: Performance Ease of use by other developers How error-prone/opportunities for bugs [Anything else you can think of]

• How do I reset my password?

  - by doug

  I inherited a machine with Ubuntu desktop installed. It has a password in place and I have no idea what the password may be. I cannot get to the command line to use the methods I have found online. No matter how many times I press "Shift" during the boot process it still goes all the way to the desktop login. I never see grub. I am not sure which version I have but I think may be 9 or 10.

• Books and stories on programming culture, specifically in the 80's / early 90's

  - by Ivo van der Wijk

  I've enjoyed a number of (fiction/non-fiction books) about hacker culture and running a software business in the 80's, 90's. For some reason things seemed so much more exciting back then. Examples are: Microserfs (Douglas Coupland) Accidental Empires (Robert X. Cringely Almost Pefect (W.E. Peterson, online!) Coders at Work (Peter Seibel) Today I'm an entrepeneur and programmer. Back in the 80's a I was a young geek hacking DOS TSR's and coding GWBasic / QBasic. In the 90's I was a C.S. university student, experiencing the rise of the Internet world wide. When reading these books running a software business seemed so much more fun than it is nowadays. Things used to be so much simpler, opportunities seemed to be everywhere and the startups seemed to work with much more real problems (inventing spreadsheets, writing word processors in assembly on 6 different platforms) than all our current web 2.0 social networking toys. Does anyone share these feelings? Does anyone have any good (personal) stories from back then or know of other good books to read?

• Rebind Alt key to win using setxkbmap?

  - by Wayne Werner

  Hi, After an hour or two of manpage and Google searching and finding no solution or good resources, I've come for help! I have set my Caps Lock key to Ctrl using setxkbmap -option ctrl:nocaps - this works perfectly fine. However, since I use [awesome][1], and an IBM model M which lacks the meta key, I need my left alt key to replace the windows key. Using xkeycaps I was able to get this to work, except it killed my arrow keys and End. Problematic. Unfortunately, documentation on setxkbmap options are sparse. and I can't find the proper option to use. Thanks for any links/solutions.

  I'm new to Ubuntu, I'm running 12.04 64 Bit on a Dell XPS L207x with a Nvidia GT555M card. From what I could understand online I needed to install Bumblebee to get the most out of the Optimus system and better battery life. I can test the Bumblebee is working by running optirun glxgears for example. If I run just glxgears then I get the following error Error: couldn't get an RGB, Double-buffered visual. I'm also unable to run Unity 3d, which I would very much like. I'd greatly appreciate any and all help, please be gentle.

• Parsing google site speed in analytics

  - by Kevin Burke

  I'm having a hard time making heads or tails of the Site Speed graphs in Google Analytics. Our site speed is fluctuating wildly from month to month, despite a large sample (the report is "based on 100,000's of visits) and a consistent web set up (static files served from an EC2 instance running nginx behind a load balancer). Here's our site speed, with each datapoint representing a week worth of data. Over this time period we modified our source and HTTP headers to increase our cache hits on static resources by 5x. Why would it fluctuate so much? Is there any way to get more reliable information from those graphs?

• Working as an entry .Net Developer in the USA [closed]

  - by Abdullah

  I just have a question about .net entry level jobs in VA. I am a master degree student in field of software engineering but I am graduated from department of physics. I decided to work on Java first, but I have changed my mind because I don't have any Java programming background except Java class in master degree so I decided to work on C# because it was easy to me to work with Visual Studio and it's fun to me to work with SQL database and HTML stuffs. And I am a member of a IT consultant company in Reston where I took course from there about .net and I created online recruitment system for their web site. Now I am applying for CPT (internship) but I didn't work in a company as a .net developer so I don't have experience. Here is my question. If I get CPT and find a job, what do software companies want from an entry level .net developer? and what do they ask as interview questions?
