• what's the overhead when allocating objects/arrays in Java?

  - by Gnijuohz

  How many bytes an array occupies in Java? Assume It's a 64bit machine and also assume there are N elements in an array, so all these elements would take up 2*N, 4*N or 8*N bytes for different types of array. And a lecture in Coursera says that it would occupy 2*N+24, 4*N+24 or 8*N+24 bytes for a N element array and the 24 byte is called overhead, but didn't explain it. Also objects have overheads, which is 16 bytes. What exactly are these overheads? Also, do these overheads only exist in Java? How about C, C++ and Python?

• READ_ME_FIRST: What Do I Do All of Those SPARC Threads?

  - by user12608550

  New Oracle Technical White Paper: READ_ME_FIRST: What Do I Do All of Those SPARC Threads? Executive Overview With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources. In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading.

• How to deal with meta data with drop downs?

  - by Mangesh Jogade

  Please advise how to handle following scenario in web application. I have a drop-down which is populated using meta-data from table A. When form is submitted this drop down data is stored in table B. While displaying existing data, it is populated using data stored in table B. While copying existing data, it is copied using data stored in table B. I want to achieve following goals: While displaying existing data I must display data irrespective of current meta data (to explain, even if some options are removed from metadata I still display them). When I copy existing data only current data should be copied(that is if some options are removed from metadata I should not copy them). I understand that I can do this by scanning metadata every time I copy existing data, however if there are thousands of such drop down exist, it is definitely not desirable to scan complete metadata for every drop down. How can I handle such situation in web application?

• FBO rendering different result between Galaxy S2 and S3

  - by BruceJones

  I'm working on a pong game and have recently set up FBO rendering so that I can apply some post-processing shaders. This proceeds as so: Bind texture A to framebuffer Draw balls Bind texture B to framebuffer Draw texture A using fade shader on fullscreen quad Bind screen to framebuffer Draw texture B using normal textured quad shader Neither texture A or B are cleared at any point, this way the balls leave trails on screen, see below for the fade shader. Fade Shader private final String fragmentShaderCode = "precision highp float;" + "uniform sampler2D u_Texture;" + "varying vec2 v_TexCoordinate;" + "vec4 color;" + "void main(void)" + "{" + " color = texture2D(u_Texture, v_TexCoordinate);" + " color.a *= 0.8;" + " gl_FragColor = color;" + "}"; This works fine with the Samsung Galaxy S3/ Note2, but cause a strange effect doesnt work on Galaxy S2 or Note1. See pictures: Galaxy S3/Note2 Galaxy S3/Note2 Galaxy S2/Note Galaxy S2/Note Can anyone explain the difference?

• Multi Monitor Setup Problems

  - by Shamballa

  I have Ubuntu 10.04 LTS - the Lucid Lynx. I have until recently been using a nVida Graphics card (NVIDIA GeForce 9800 GT) with two monitors attached, this all worked fine and dandy. A couple of days ago I bought two new identical LCD monitors for a multi monitor setup and two ATI graphics cards (ATI Sapphire Radeon HD5450). NOTE *All monitors work fine in Windows XP, 2k, Vista and 7 After I had booted into Ubuntu only one display came on, that I kind of expected anyway, then I removed the driver for the nVidia card and downloaded the ATI version which gave me the ATI Catalyst Control Center - in that only two of the displays were showing the third was disabled and showing unknown driver. I enabled the third monitor that stated "Unkown Driver" and had to reboot, upon reboot none of the displays work. I restarted and booted up into recovery mode and from now that is only what I can get into using a failsafe driver. It seems according to the log that a server is already active for Display 0 and I have to remove /tmp/.X0-lock and start again. This is what the log file is saying: Fatal Server Error Server is already active for display 0 if this server is no longer running, remove /tmp/.X0-lock and start again. (WW) xf86 closeconsole: KDSETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETSTATE failed: Bad file descriptor ddxSigGiveUp: closing log I have tried looking at my xorg.config file but unfortunately I have not really got a clue as to how it "should" be - I have tried regenerating it using this command from a terminal: sudo dpkg-reconfigure -phigh xserver-xorg but that had no effect so I am currently stuck in failsafe driver mode but two monitors are active but are mirroring each other. I hope that this is not to long - looking back I have been going on a bit! but I am just trying to explain as much as I can... I have asked this on Linuxquestions but nobody seems to know either or at least I have not had any responses. Could some kind soul please help explain what I can do from here? I would be eternally grateful. Chris * Update * Removing xorg.conf does nothing other than allowing me to use only two monitors - using the command: sudo aticonfig --initial generates the xorg.conf file below: but does not work either - I just get two monitors...

• What is Continous Integration (CI) and how is it useful?

  - by Geek

  Can some one explain to me the concept of Continious Integration, how it works in an easy to understand way? And why should a company adopt CI in their code delivery workflow? I am a developer and my company (mainly the build team ) uses Team City. As a developer I always checkout, update and commit code to SVN but never really had to bother about TeamCity or CI in general. So I would like to understand what is the usefulness of CI? Is CI a part of Agile methodologies?

• Cinnamon on Ubuntu 12.04 stoped working after menu edditing

  - by Presbitero

  I have recently installed cinnamon on ubuntu 12.04 with success. After installing MS Office with wine my menu got messy so I tried to edit it with alacarte. After having found out that alacarte is not the proper way to edit it, I right clicked on the menu icon to edit. After just a few editing steps it breaks and cinnamon stopped working (no menus, no desktop icons, no applets, no window decoration, nothing). Now, when I login with cinnamon I just get the background image. I can login with gnome though. I have tried to completely remove cinnamon and nemo and reinstall it but it didn't help. I have no idea of how to get any king of diagnostics so if you ask something please explain how to do it or post a link with explanations. Many thanks for the help, I hope I will not need to format the pc again to make it work.

• Why do we use to talk about addresses and memory of variable in C?

  - by user2720323

  Why do we use to talk about addresses and memory of variable in C, where in other languages (like in Java, .Net etc) we do not talk about variable address and memory in a program, we will directly use the variables. But in C Language we are listening the word address and memory. How to explain this? I hope C is high level language designed over the assembly language. So C is a thin layer over assembly language (in assembly language we will use memory locations to store a variable and track a variable). But in other languages these addresses and memory related things are wrapped in that specific language, so that we will not listen these words.

• Space in img:s "ALT" attribute good/bad for search engines?

  - by Camran

  I am trying to make it easier for search engines to crawl my website, as it is almost 100% dynamic. I have a couple of transparent images which are actually links to sections of my page. I wonder, if I add an "alt" attribute containing space characters to explain the target, will this improve SE rankings etc? For example: <img src="blabla.png" alt="post new classified"> Or will this just result in errors? Ànd, what should I put in the alt attribute if I can't use space? PS: Another different and short question, will javascript-rich content make a page less important to crawlers? Thanks

• Is it normal to sometimes take a while to get even basic things working in software development?

  - by user1092719

  This is a little hard to explain because it's a really generic question, but bear with me... I find that when I am doing or recreating basic things from scratch (i.e. without the help of libraries), sometimes it feels as though I'm taking much more time to do the task than is actually needed. I am not new to programming or development & design concepts and have worked extensively with around 9 languages and various platforms and paradigms over 5/6 years. Although I don't yet have any academic qualification for programming and have learned almost exclusively from the Internet, I have been told that the quality of my code is excellent by those with qualifications. So, I don't think I'm a bad programmer because I really love doing it and working with software architecture, but maybe I'm slow? Or is it normal to take sometimes longer than it seems necessary to do basic tasks?

• How do I find the dependencies for a program before trying to compile it?

  - by Ubuntu_beginner

  I was trying to cross-compile a program for ARM. While compiling I was very much irritated as I had to look for a number of dependencies e.g fatal error: abc/xyz.h: No such file or directory compilation terminated. After ensuring that compiler gets the missing files, when I recompiled, I got same error for about 30 files. I have no idea if that is normal behaviour. If it is normal, is there a method which can help the compiler find the dependencies on its own? If that is not normal, then please explain what I'm doing wrong.

• In what stage of development should comments be written?

  - by CurtisHx

  I'm a student working an internship at a larger company, writing small business apps in C#. I've noticed that I don't comment my code as I write it. Rather, I comment my code when I'm in the debugging stage of development. As I'm tracking down bugs, I'll run across a block that makes me think "hmm...that might confuse someone in the future. I'd better comment that", and I'll add the appropriate comments. All of my comments are done this way. Is this an appropriate way of commenting? Should comments be written as the code is written? Or does it really matter when the comments are written, as long as they adequately explain why this block is used?

• After one has made many grid based puzzles how does one make then into a PDF ready for printing

  - by alan ross

  After one has generated many grid based puzzles like sudoku, kakuro or even plain crosswords and now one has to print them in a book. How does one make a pdf (book file) from them automatically. To explain the question better. One has the puzzle ready in computer format like ..35.6.89 for all nine rows. The dot being the empty cell. How does one convert then to a picture on a PDF page complete with box, automatically without doing them individually and then print a book from the pdf file. As can be seen there are other things also printed on the page all this is done automatically.

• Instalar o Ubuntu / Install Ubuntu

Now I'm trying to update to version 11.10 but I get an error message saying it is not possible to upgrade, I decided to install a partition that I created the part, but when I start the PC directly opens Windows 7 does not appear to me the option to choose which want to start the operating system. I formatted the partition where you had installed ubuntu, I've been looking for tutorials where you learn how to install ubuntu on a partition part to try to understand what my problem. I wonder if I can explain how to install ubuntu on a partition that part so that when I connect the PC to show me the option to choose which system I want to start.

• Learning to program without a computer

  - by ribrdb

  I have a friend in prison who wants to learn to program. He's got no access to a computer so I was wondering if people could recommend books that would be a good introduction to programming without requiring a computer. Obviously he's going to need to keep learning once he gets out and has access to a computer, but how should he get started now (he's got lots of free time to read). Based on his goals I think ruby or javascript/html5 might be good paths for him to start down, but really for now it's most important to explain the ideas. Even if it's all pseudocode. These need to be physical publications, paperbacks are preferred, and consider that he's got limited shelf space so large books could be a problem.

• Miracles in your work

  - by MobileDev123

  Lot of things has been discussed that can be taken as negative things about programmers, Lets discussed about something good and unexpected happenings in your programmer life... Like: (after R&D of two days and a lot of disappointments ) You just spend an hour with your PM to explain that some feature having some problem and we are unable to release this module in today's beta... after a lot of arguments you are given an hour to make your app work without this module, you sit on your workstation to make a release and all of a sudden you found a silly problem behind that module..... (you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B. I know my English is not that good and that's why I'm open to every linguistic mistakes needed to be corrected)

• Hiring developers - listing IDE as a requirement?

  - by suslik

  I've been looking at some job postings and noticed that a fair amount of them list IDEs under the 'required skills' section, even for senior positions. This is not localized to one company either, but rather it's something that comes up once in every few postings. I am perplexed by this job requirement, as my mentors and some of the best coders I've seen in my life were VIM/Emacs ninjas. Similarly, when I work with people I don't much care what tools they use as long as they are productive on the team. Can someone please explain the rationale behind hiring managers making IDEs an official job requirement?

• What things to take into consideration when refactoring code?

  - by JustaPro

  Code refactoring is a "disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior" Could anyone explain this definition? I find it kind of blurry. Which is the best technique to do it? Are these the only ones? Which are the obstacles one would meet when refactoring code? What to take into consideration when switching between IDEs? Do tools which help refactoring exist? If yes, which one would you recommend using? Any references to links where I can find out more on this subject or to books that have been written are welcomed. The questions above are for any programming language, but specific examples are appreciated. Anything that would clarify this for me is.

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.

• I just updated to 12.04 from 11.10 and now the Unity bar is very sluggish and even the menus do not show on the panel

  - by jredkai

  Like the title says, I just upgraded to 12.04, I know it is only beta but I'm having problems with the Unity bar and the panel with the menus. First the Unity bar is acting very sluggish..I really don't know how to explain it. Also with the menu at the top, it keeps a strange little black bar on everything, even across my tabs in Firefox, it also doesn't let me see any of the menus, well they flicker and you sort of have to guess where everything is. I'm at a loss, I've already ran updates a couple of times to see if I missed something. I really hope I don't have to completely redo my whole Ubuntu setup. Any help would be greatly appreciated.
