• JSR 348, 355, and 358: Moving JCP Forward

  - by arungupta

  The three-step JCP evolution consists of the following JSRs: • JSR 348, JCP transparency • JSR 355, Merging the two existing Executive Committees • JSR 358, complex issues moved postponed from JSR 348 The JSR 348 is already completed and JSR 355 is scheduled to be complete later this year. JSR 358 was recently filed and plans to revise several items such as modify the JSPA, Process Document, and a large number of complex issues. Because of the nature and scope of work, the Expert Group consists of representatives from all companies in the Executive Committee. Following the process set by JSR 348, all the work is done in open at jsr358.java.net. All the email discussions are here and JIRA here. Read Patrick Curran's blog for more details as well. The JSR review ballot ends on Jul 9th however the work has already happening for the past few months. Now is your chance to contribute and make JCP more effective!

• Do open world games need less backstory?

  - by Raceimaztion

  I've played a few open-world games and really enjoyed them, though the ones I've really enjoyed have generally received complaints about how little story there is to them. The Saboteur is one example of this. Fully open-world, good enough story (for me, anyway), engaging gameplay, and still has received complaints in reviews about not having enough story. Do open-world games actually need a full, all-encompassing story? Or can fun and engaging gameplay fill in the gap and let the designer get away with a slightly less complete story?

• Is this a valid HTTP response? [migrated]

  - by fatmck

  I am writing a web server using C++, which responds the following for all requests: static std::string rsp[] = { "HTTP/1.1 200 OK\r\n", "Server: WebServer\r\n", "Content-Type: text/html\r\n", "Content-Length: 3\r\n", "Connection: close\r\n", "\r\n", "123" }; the content "123" can be successfully shown in browser. But when I use apache-ab to do a test, ab always show errors like this: ab -n 1 -c 1 http://127.0.0.1:1080/ apr_socket_recv: Connection reset by peer (104) I thought that I'm closing the socket too quickly, so I commented the close() function. But ab just hold, ab seems to be waiting for a complete response.

• Question about initial interview for job [closed]

  - by JustLikeThat

  So I feel kind of stupid having to ask this but tomorrow I have a phone interview with a good company. Phone interviews themselves not a big deal for me, but having to tell them my salary expectations is. The position that I'm applying for is a mid-level software engineer, I fit all of the requirements (I'm not overly qualified by any means), and I want to be sure I'm not asking for an amount that would be absurd or too little. Now, assuming I get a second interview and have to complete some sort of puzzle/code/work, they may pay me +/- whatever I asked for based upon their evaluation of my work. What I'd like to know, is what is a good amount to ask for? Or am I completely wrong with my assumptions? Either way some advice would be much appreciated!

• Data transfer from 12.04 to 14.04 using same hostname?

  - by Mark

  I've been using my 12.04 server for a year and a half. I'd like to install 14.04 on a new drive and transfer all my data over once that is complete. I have 720GB of files to to deal with. 12.04 was setup using LVM. I'd like to use the same hostname. I'd prefer a clean install as opposed to an upgrade. What would be the best way go about this? Is it as simple as booting to the new install and mounting the 12.04 VG? I suppose I'd have to manually set up LVM on 14.04 if I want to use the same hostname.

• 3D Mesh Collision Help

  - by BlackAfricano

  I am new to XNA (I have only been working in it for a countable number of weeks) as well as to these forums (I have only made 1-2 other posts), so this may seem like a strange request, but I am wondering if anybody knows about more advanced collision in XNA. So far I have only been able to figure out BoundingSphere's which seem to be the simplest of the methods, and I was thinking of looking more into BoundingBoxes because the game I have is a 2-3D platformer. The problem I realized was that if I wanted to get any more advanced than stages in the shape of a box, I would face some immediate dilemmas. I was hoping somebody here was knowledgeable on the subject and could inform me where I could get started learning how to do something like this: https://www.youtube.com/watch?v=ekMD_Gtt8d4 Although the game in this video isn't very pretty, the mesh collision looks like what I'm looking for. I am hoping for the most complete solution, if possible.

• Javascript Only Search Method [on hold]

  - by user2118228

  I need to put a search function on a website that is going to be on a CD-ROM with no access to the internet. It has 80 pages, and about 500 'items', so I'd prefer to not have to hard code 100's of 'if statements if possible. I've found a few programs you can buy that will index and generate results (Zoom Search, JSS Index, The German Guys') but there are odd quirks with each one. Plus I would rather code it myself to get complete control over it, and to really understand what it's doing. Basically searching for a few words would display the product image and description; clicking on that would take you the related URL. This is kind of complicated, I can't find an easy solution not dealing with hundreds of if Statements. Has anyone ever created anything like this or know a better method? I'm not really sure a better way to go about this. I've used PHP/MYSQL for search results before, but this cannot run any php.

• What steps should be taken to ensure that an open source database gets ready for production?

  - by I_like_traffic_lights

  I am considering using GridSQL in a production environment. However, I do have some indications that it is not ready. One is that it got excluded by the offering of EnterpriseDB a while ago, and the forums seem to report a few wrong results and relatively severe bugs. The alternatives to GridSQL, however cost around 100.000$ to buy, so I was thinking to utilize some of this money to ensure that GridSQL gets ready for production. At the same time, I could risk spending 50.000$ and months of work on the development of GridSQL, just to discover that the design was flawed and that a complete rewrite is needed. Then I would have to buy the commercial alternatives to GridSQL and the existence of my startup would be at risk. Question What steps would you take to ensure that there is as little risk as possible that the worst case scenario described above would happen? It is unrealistic that I could do much testing nor code review/coding myself (I am also not the best developer), so please describe where to find the guys that would need to do the work.

• Microsoft revient sur les nouveautés de Windows Phone 8 et les implications du "Shared Windows Core" pour les développeurs

  Microsoft revient sur les nouveautés de Windows Phone 8 et les implications du "Shared Windows Core" pour les développeurs Windows Phone 8, la prochaine mise à jour majeure de la plateforme mobile de Microsoft a été présentée il y a quelques semaines, lors de l'événement Windows Phone Summit de San Francisco. En rupture « presque complète » avec la version précédente, cette mouture introduit un nombre assez important de nouvelles fonctionnalités et améliorations. Parmi ces nouveautés, les plus remarquables pour les développeurs sont sans aucun doute le support du code natif (C/C++), et le « Shared Windows Core ».

• Any good site that teaches C++?

  - by Shinmaru

  I am searching for any good site that teaches C++, that can explain most to all things about it(general) and has a decent active community. About Me: I am new to programming(knows nothing of it, so please bare with me), I have only learned(to a very basic form) LUA scripting Language, so yes I am your complete newbie. I got interested in programming, from scripting in LUA, so you can say it was my small stepping stone, One would basically take a course in college, but not everyone is well funded for that and I can't buy books for the same said reason(yes I'm somewhat poor, only money for essentials and bills), I'm not trying to get sympathy, just stating my conditions. and Please, something in between the lines of 'Programming for Dummies'(I'm not the brightest crayon in the box), I know this will not be easy, but your help will be most appreciated. I would learn for either Windows and/or Linux/Unix. I use both. Site(s) I know: Cplusplus.org(quite inactive and tutorials are a little for the programming savvy.

• How does the HUD prioritize commands?

  - by user50849

  Every now and then I want to reach the "Edit Preferences" menu item in Firefox, and the HUD makes this very convenient. ALT + "Edi" will suggest exactly that to me. Something that I find annoying however is that if I complete the work "Edit" instead, the HUD will switch to suggest "Network Edit preferences" instead. While this is a perfectly valid match as well, it seems like an inconsistent behaviour to me. Could someone explain in more detail how the matching works, so that I can make better use of the HUD?

• 12.04 install now just blank screen

  - by bull

  I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

• Shutdown problem in ubuntu 12.04 LTS

  - by sudeep

  I am using Ubuntu 12.04 LTS and I'm getting a serious bug: When I try to shutdown my system, my screen goes blank but my CPU fan keeps running, i.e. the processor is still working but I am not able to see anything on my screen. I need to power off my machine for a complete shutdown. I am using a desktop with an Intel P4 processor. I found a solution on the internet involving modifying the GRUB config file. But even after doing so I wasn't able to eliminate the issue.

• How to begin serious game development (in C++) [closed]

  - by Rondogiannis Aristophanes

  I would like to start developing games. I have tried before Game Maker 8, which was a very easy way to start creating games, if you were new in game development. Then, I tried Unity 3D, which was a much more serious and complete tool to create computer-games, and required some experience. And now, I would like to start creating games, and don't use any special environment or developer, but just code (in C++ preferably). So, here is my question: from where should I begin, if I would like to start programming games? Thanks in advance. Note: I work in ubuntu 10.04, I can also use windows 7, but I prefer ubuntu.

• Workflow of sharing code for small teams

  - by Mihalis Bagos

  Problem is, we have developed a small CMS, that is different per implementation (currently). Of course development of this is never complete. Sometimes, we are working on more than one project that implements it (by copying-pasting the code files of the CMS to each project), and we add a new feature that we want to share on other projects as well (these can be small ones too, ie a custom ajax JSON controller - we use MVC) What we want to do is quickly and uniformly share the code with all other projects, via a version control system (or something similar), and generally organize the workflow as we know this isn't a very good workflow that we have. What would you suggest? Also, at the momment, the software we use is Visual Studio 2010, so we are strongly considering TFS, but even if we get it we still don't know the ideal workflow, or even if TFS supports what we want to do. Edit: Also note, we have specific implementations that have modifications over the CMS base that we want to KEEP only in the project area. (ie: a specific feature that we DONT want to share with the base CMS code)

• Are there any resources for motion-planning puzzle design?

  - by Salano Software

  Some background: I'm poking at a set of puzzles along the lines of Rush Hour/Sokoban/etc; for want of a better description, call them 'motion planning' puzzles - the player has to figure out the correct sequence of moves to achieve a particular configuration. (It's the sort of puzzle that's generically PSPACE-complete if that actually helps anyone's mental image). While I have a few straightforward 'building blocks' that I can use for puzzle crafting and I have a few basic examples put together, I'm trying to figure out how to avoid too much sameness over a large swath of these kinds of puzzles, and I'm also trying to figure out how to make puzzles that have more of a feel of logical solution than trial-and-error. Does anyone know of good resources out there for designing instances of this sort of puzzle once the core puzzle rules are in place? Most of what I've found on puzzle design only covers creating the puzzle rules, not building interesting puzzles out of a set of rules.

• Your favorite LiveCD

  - by sova

  Perhaps this is a question better suited for linux.se but since I have servers on all environments I was wondering what your favorite LiveCD is. Wiki defines this, for those unfamiliar, as a CD or DVD containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive. Live USB flash drives are similar to live CDs, but often have the added functionality of automatically and transparently writing changes back to their bootable medium. I tend to stick with Knoppix, and today I have to register the machine on the network before I can get any of my utilities running via IP. Any suggestions?

• Dual Boot not recognizing new hard drive

  - by Grove

  I am a complete Linux newb..which will become obvious shortly. The story: I wanted to dual boot with Ubuntu. I already had windows on 1 hard drive (320gb), and I wanted Ubuntu on a 2nd hard drive (2tb). I setup the partitions using the "Something else" option - I left the first hard drive alone, and put a swap and a ext4 partition on the 2nd hard drive. When it asked me where the bootable device was, I put the first hard drive. The problem: Now that Ubuntu is installed and grub lets me pick which os to boot to, I boot to ubuntu JUST FINE. BUT when I go to the home folder and look at devices, the only drive showing is the 320 gb/old hard drive that windows was installed on. I can not see the 2 TB hard drive anywhere. This is strange because I setup the Ubuntu partition to be the 2 TB hard drive and I thought I installed ubunto on that partition. Thank you for your time and patience :)

• Will you still play a good Red Alert 3 mission map? [closed]

  - by W.N.

  I've been creating a RA3 mission map (play in Skirmish), most likely a remake of RA2 Yuri "To the Moon" mission, with more interesting elements. However, because of my work, the process was corrupted for more than a year. And now, I see that very few people still play RA3. So, should I continue making this map? Because there're still a lot of work to complete this map. I can assure you, the mission will be interesting. However, if few people play it, there's no need to waste time to it. Please give me some advice. Thank you.

• What would one call this architecture?

  - by Chris

  I have developed a distributed test automation system which consists of two different entities. One entity is responsible for triggering tests runs and monitoring/displaying their progress. The other is responsible for carrying out tests on that host. Both of these entities retrieve data from a central DB. Now, my first thought is that this is clearly a server-client architecture. After all, you have exactly one organizing entity and many entities that communicate with said entity. However, while the supposed clients to communicate to the server via RPC, they are not actually requesting services or information, rather they are simply reporting back test progress, in fact, once the test run has been triggered they can complete their tasks without connection to the server. The request for a service is actually made by the supposed server which triggers the clients to carry out tests. So would this still be considered a server-client architecture or is this something different?

• What reference point/ tutorial could I use to help me make a "Ball rolling" game in flash?

  - by user1798964

  I am a complete newbie to programming, only took high school Computer science so I kind of know what im doing, I just want to know how I can make a ball rolling game that I want to make, could anyone show me an example of a good "ball rolling game" that has good physics and everything, I have tried to use Box2D for the physics portion of the game, but I found that using that is just code and I can't figure out how to make the graphics and details of the world I want to make in my game, all I would like to do would have a game that has the collision detection and physics of box2d only apply to one ball in it and use the left and right keys to move it. sorry if I am too unclear, if anyone could show a tutorial or something to me on how to make a proper "Ball rolling" game that has good physics that would be appreciated, thank you for taking the time to read this
