  • C++ networking simple send and receive

    - by Wallter
    I'm trying to link 10 computers together, the program i would like to write would have one 'control' computer. From what I've looked up this computer would take all the packets sent over the network and do a echo with them... right? The other computers would need to be able to send information (then echoed to the others) to the 'control' ... is there a easy! or simple way to do this? From what I've seen i want a non-blocking socket? I have looked into sockets and such but for an armature programmer like me, this seems like a daunting task :) I'm kind-of looking for an easy class implication that has a send() and an event driven recv(). I'm not going to be sending that much information over the network.

  • What's causing "Unable to retrieve native address from ByteBuffer object"?

    - by r0u1i
    As a very novice Java programmer, I probably should not mess with that kind of things. Unfortunately, I'm using a library which have a method that accepts a ByteBuffer object and throws when I try to use it: Exception in thread "main" java.lang.NullPointerException: Unable to retrieve native address from ByteBuffer object Is it because I'm not using a non-direct buffer? edit: There's not a lot of my code there. The library I'm using is jNetPcap, and I'm trying to dump a packet to file. My code takes an existing packet, and extract a ByteBuffer out of it: byte[] bytes = m_packet.getByteArray(0, m_packet.size()); ByteBuffer buffer = ByteBuffer.wrap(bytes); Then it calls on of the dump methods of jNetPcap that takes a ByteBuffer.

  • How can I know if a computer supports hardware-assisted virtualization before I purchase the computer?

    - by Poaters
    I'm an iPhone programmer who is no longer in possession of a personal Mac computer on which to use XCode. I have two Windows desktops, and I would like to run OS X in VMWare rather than purchase Apple's expensive hardware. However, neither of my machines supports hardware-assisted virtualization, which is required to virtualize OS X. I went shopping online for a computer today, since I've been planning to purchase a laptop anyway, but sites like Best Buy don't appear to give any indication of whether or not a product supports this. Is there any other site out there or some trick to figuring this out other than buying the machine and running Microsoft's nifty little detection tool?

  • Browser extensions to re-render the page using an updated version of my CSS file, without reloading the page itself

    - by Eduardo León
    I want to learn Web UI design. (I know, I know. Being a programmer puts me at a disadvantage. But I want to try anyway.) Thus, I would like to "debug" my CSS files. Once of the biggest annoyances I have found is that I cannot test a change in my CSS files without reloading the whole page. Sometimes, the page is too big. Sometimes, a lot of elements were brought to the page after lots of clicks, because my pages rely too heavily on AJAX. Sometimes, I just hate hitting Command+R all the time. Is there any extension for any of the major browsers (preferably Safari and/or Chrome) that re-renders the page using an updated version of the CSS file, without reloading the whole page itself?

  • Can I program Nvidia's CUDA using only Python or do I have to learn C?

    - by Aquateenfan
    I guess the question speaks for itself. I'm interested in doing some serious computations but am not a programmer by trade. I can string enough python together to get done what I want. But can I write a program in python and have the GPU execute it using CUDA? Or do I have to use some mix of python and C? The examples on Klockner's (sp) "pyCUDA" webpage had a mix of both python and C, so I'm not sure what the answer is. If anyone wants to chime in about Opencl, feel free. I heard about this CUDA business only a couple of weeks ago and didn't know you could use your video cards like this. thx

  • Help me refactor this nasty Ruby if/else statement

    - by Suborx
    Hello, so I have this big method in my application for newsletter distribution. Method is for updating rayons and I need to assign a user to rayon. I have relation n:n through table colporteur_in_rayons which has attributes since_date and until_date. I am a junior programmer and I know this code is pretty dummy :) I appreciate every suggestion. def update rayon = Rayon.find(params[:id]) if rayon.update_attributes(params[:rayon]) if params[:user_id] != "" unless rayon.users.empty? unless rayon.users.last.id.eql?(params[:user_id]) rayon.colporteur_in_rayons.last.update_attributes(:until_date => Time.now) Rayon.assign_user(rayon.id,params[:user_id]) flash[:success] = "Rayon #{rayon.name} has been succesuly assigned to #{rayon.actual_user.name}." return redirect_to rayons_path end else Rayon.assign_user(rayon.id,params[:user_id]) flash[:success] = "Rayon #{rayon.name} has been successfully assigned to #{rayon.actual_user.name}." return redirect_to rayons_path end end flash[:success] = "Rayon has been successfully updated." return redirect_to rayons_path else flash[:error] = "Rayon has not been updated." return redirect_to :back end end

  • Up to date Ruby On Rails books?

    - by Earlz
    Hello, I've been trying to learn Rails for a while now and I just can not piece it all together with random blogs and SO questions, so I've decided I need a full book/ebook. Can anyone suggest a good one? I've been looking at Agile Web Development With Rails 4th edition. There is an old question about Ruby On Rails books but it is from 2008 and there has been new Rails releases since then. I basically would like a book that is more than a reference, but also doesn't assume I'm a non-programmer. Also, I already know a lot of Ruby. So, what books would you recommend that is up to date and also doesn't treat me like a baby?

  • Mod_rewrite on Alias directory

    - by crunchline
    I am moving from a WIMP setup to a WAMP setup. My images are on a separate drive. I need a default image served, when a file is not found. Currently it returns a 404 on images not found in the /images directory, and the 404.jpg is displayed for files not found on all the other directories. I tried changing [L] to [PT] but that did not do anything. in httpd.conf Alias /images "D:/images" in .htaccess RewriteCond %{REQUEST_FILENAME} !-s RewriteRule ^.*\.(gif|jpg|png)$ /404.jpg [L]

  • JVM specification and Java compiler code useful for SCJP preparation ?

    - by BenoitParis
    I'm preparing the SCJP exam with the almost official study book ("SCJP Sun Certified Programmer for Java 6 Exam 310-065") I understand that Java programming is writting code that fulfills a certain high-level contract; So that Java can stay platform-independent. However, I have trouble understanding and remembering things when it comes to highly specific SCJP items (and they are numerous) The book stays high-level and does not provide examples of how one compiler would handle things. This is the same thing for runtime issues (JVM level): things are too much abstract for me. Rules often seems arbitrary and therefore, with no well defined purpose, are difficult to remember. Or maybe it's that sometimes I just don't get the underlying purpose. And here is the question: Would a JVM specification and/or some java compiler code help in preparing the SCJP? Have you had the need for such material or is the book sufficient enough? Also, please share the resources you used, apart from the book.

  • howt setup remote access into computer behind 2 routers?

    - by Steve Wasiura
    I can setup remote access to a pc behind a single router/firewall by using NAT and Port Forwarding, simples! But there is a customer that shares an internet connection with another office, and they are behind a second router firewall. I drawed a picture with my crayons but I can't attach it because I'm a new account on SF. see it here: http://i.imgur.com/b3FDx.png So how would I setup remote access to the pc that is beind the second firewall? It must be something about static routes, i.e. if I hit the wan ip on port 4905 I want it to forward it to 10.0.0.30 by going through 192.168.1.10 so a route statement like for all requests to 10.0.0.30, use 192.168.1.10 ? and ass u me router 2 has a static gateway ip of 192.168.1.10 and need a standard NAT on router 2 to point port 4905 to 10.0.0.30 is this the right way, any tips? both routers are netgear consumer equipment. thanks

  • Most frustrating programming style you've encountered

    - by JaredPar
    When it comes to coding style I'm a pretty relaxed programmer. I'm not firmly dug into a particular coding style. I'd prefer a consistent overall style in a large code base but I'm not going to sweat every little detail of how the code is formatted. Still there are some coding styles that drive me crazy. No matter what I can't look at examples of these styles without reaching for a VIM buffer to "fix" the "problem". I can't help it. It's not even wrong, I just can't look at it for some reason. For instance the following comment style almost completely prevents me from actually being able to read the code. if (someConditional) // Comment goes here { other code } What's the most frustrating style you've encountered?

  • Making Windows 7 default to "All Files" when opening a document?

    - by krebshack
    I'm taking over an old coworkers job and part of that means I'll be working on various IFS tickets without any real ERP experience. I'm working with one user who is trying to check in documents in IFS. Right now, IFS defaults to JPEGs and then she has to select "All Files" in order find PDFs. Example: http://i.imgur.com/xK0iAfF.png As much as I'd like to say "it's one extra step, come on" the user's manager has insisted it interrupts her workflow and asked us to get on it. I've spoken with our IFS experts and they're unaware of any setting that would make the open dialog default to All Files in IFS. I've searched in Google for any setting in Windows 7 that would do that - but those have been unsuccessful - I keep getting results about changing which program opens a specific file type.

  • Graphing per-user CPU usage on a Linux machine

    - by mart1n
    I want to graph (graphical output would be great, i.e. a .png file) the following situation: I have users A, B, and C. I limit their resources so that when all users run a CPU intensive task at the same time, those processes will use 25%, 25%, and 50% of CPU. I know I can get the real-time stats using top but have no idea what to do with them. I've searched through the huge top man page but haven't found much on the subject of outputting data that can be graphed. Ideally, the graph would show a span of maybe 30 seconds. Any ideas how to achieve this?

  • Convince teammates to follow standards

    - by folone
    There's always one or two guys, who think, they are great programmers, and they don't need any literature/specifications/etc. They usually write awful code, that makes you want to hurt them. They catch and suppress Throwable's, return null's, concatenate String's in large loops, do other stupid stuff. So the question is — How do I make such a person follow best practices and specifications? He does not listen (cause he's the best programmer), team lead does not give a damn ("It actually works, so why changing it?.."), and I'm actually tired of rewriting that awful code on my own. What do I do? What would you do?

  • Is it better to adopt the same technologies used at work to be effective on your home projects ?

    - by systempuntoout
    Is it better to start developing an home project using the same technologies used at work to be more productive and effective? I'm not talking about a simple hello world web page but an home project with all bells and whistles that one day, maybe, you could sell on internet. This dilemma is often subject of flames between me and a friend. He thinks that if you want to make a great home-made project you need to use the same technologies used daily at work staying in the same scope too; for example, a c++ computer game programmer should develope an home-made c++ game. I'm pretty sure that developing using the same technologies used at work can be more productive at beginning, but surely less exciting and stimulating of working with other languages\ides\libraries out of your daily job. What's your opinion about that?

  • What wiki tools exist to generate shippable user doc from a wiki?

    - by tletnes
    I am looking into using a wiki (prefer mediawiki, but not a req.) as the repository for developer generated documentation (User Guides, Release Notes, Application Notes, Errata, etc.) from a collaborative/easy-to-update point of view a wiki seems like a good match, however since this documentation will ultimately ship to customers we want to be able to export the documents in their final state (e.g. during the release cycle) to static versions that no longer include histories. Ideally the export would leave the document n a form where errors could be easily fixed by a non-programmer It would be good if niceties like section ordering and table of contents were available, or easy to add after the fact. Are any tools with features like these avalible?

  • What do you tell people your profession is? [closed]

    - by user110296
    My technical title is Member of the Technical Staff, and like you most of you, I design/write code for a living. I can never decide what to answer when someone asks what I do for a living? Software Developer? Software Engineer? [Kernel] Programmer? Computer Scientist? These all seem to have various bad connotations. I guess I like Software Engineer the best, but unfortunately this term has been coopted by people who don't actually code. I made the mistake of taking a 'Software Engineering' class, and realized that I definitely don't want to be associated with people who major in this. Probably this is too subjective, so feel free to community wiki it or whatever, but I think it is a valid question and I would like to hear what others have decided on and their reasoning.

  • Is there a way to increase how much is cached for thumbnail views of pictures?

    - by JimDel
    Is there a way to increase how much is cached for thumbnail views of pictures? If I'm looking through a folder of .png files for example, with "medium" set as the view size. The screen will eventually fill all the thumbnails with the appropriate pictures. But as I scroll down it takes a while for the pictures to fill in again. I would like a way for "off screen" pictures to fill in before I get the that section of the screen. Is there a way to do this? Thanks

  • Which Visual Studio 2010 edition for sole developer

    - by bufferz
    I am the sole .net developer for a small company. My projects span many .net technologies including WinForms, WPF, SQL, XNA, Linq, WCF, WTF?, and others. I struggle staying on top of all these projects so I'm looking to make my life easier with the release of VS2010. Without a mentor I rely heavily on StackOverflow and whatever else Google comes up with. Should I convince my company to get an edition with an MSDN subscription? Is it one of those things where once you have it, you can't imagine life without it? What about the source control that comes with VS2010, do you all find it better than an SVN server? We're looking to hire another programmer this year, would I be best off getting a Team edition of VS2010 to be best prepared for that hire? Thanks!

  • Why are my DNS Lookups so long (300+ms) when accessing my web site?

    - by Travis
    I'm running a Fedora 11 server with Apache 2. I'm trying to optimize so things are as fast as possible from the server side, and I'm noticing (via Firebug for Firefox) that upon loading the homepage of one of the sites on the web server that for every file it loads (HTML, CSS, JavaScript, GIF, PNG, JPG, etc.), it does a DNS lookup. All of the files it is looking up are local to the server, so I'm surprised to see it even do a DNS lookup. Also, each of these lookups is in the 150-450ms range, which is way too high for my liking. I've tried adjusting /etc/resolve.conf to use Google's Public DNS servers. I restarted the network service and tapped the page again, but the numbers didn't go down. I've reverted back to the default DNS servers since I didn't see any gain. Any ideas on what is causing it to: a) do the dns lookup in the first place, and b) take so long when doing the actual lookup? Thanks in advance.

  • How to abandon a hg merge?

    - by Grumdrig
    I'm new to collaborating with Mercurial. My situation: Another programmer changed rev 1 of a file to replace 4-space indents with 2-space indent. (I.e. changed every line.) Call that rev 2, pushed to the remote repo. I've committed substantive changes rev 1 with various code changes in my local workspace. Call that rev 3. I've hg pulled and hg merged without a clear idea of what was going on. The conflicts are myriad and not really substantive. So I really wish I'd changed my local repo to 2-space indents before merging; then the merge will be trivial (i'm supposing). But I can't seem to back up. I think I need to hg update -r 3 but it says abort: outstanding uncommitted merges. How can I undo the merge, changes spacing in my local repo, and remerge?

  • what changes when your input is giga/terabyte sized?

    - by Wang
    I just took my first baby step today into real scientific computing today when I was shown a data set where the smallest file is 48000 fields by 1600 rows (haplotypes for several people, for chromosome 22). And this is considered tiny. I write Python, so I've spent the last few hours reading about HDF5, and Numpy, and PyTable, but I still feel like I'm not really grokking what a terabyte-sized data set actually means for me as a programmer. For example, someone pointed out that with larger data sets, it becomes impossible to read the whole thing into memory, not because the machine has insufficient RAM, but because the architecture has insufficient address space! It blew my mind. What other assumptions have I been relying in the classroom that just don't work with input this big? What kinds of things do I need to start doing or thinking about differently? (This doesn't have to be Python specific.)
