  • Can somebody link me to some code where there is a fantastic or a nice use of Inheritance

    - by Soham
    I strongly believe that, reading code and reading good code is key to great programming. If not one of the many. I had been facing some problems in visualizing and having a "feel" of using inheritance to better my code architecture. Can somebody give me some link to good code to emulate, where folks have used inheritance in an absolute "kung-fooey ruthless" manner [in a good way]

  • Removing the transperancy from image while keeping the actual image

    - by KPL
    Hello people, I have three images,and , they are not square or rectangular in shape. They are just like face of anyone. So,basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question.

  • Best IDE macro tools to combat the verbosity of Java syntax for someone with carpal tunnel?

    - by Carlsberg
    I have a bad case of carpal tunnel so I'm looking for an editor that would make my Java programming less painful (literally!). Does anyone have any recommendations for tools that you can add to Eclipse, Netbeans or other IDEs to produce some of the repetitive code that's common in Java syntax? Overall what would be the best code editor for this purpose? (I'm coding on Ubuntu, in case it matters).

  • Upgrading PHP 5.1 to 5.3 on Linux Server

    - by nicorellius
    I trying to find the best way to upgrade from PHP 5.1 to 5.3. The CRM software I am running on this server requires this upgrade or else I probably wouldn't even perform it, because it seems like it's going to be perhaps trickier than I hoped it would be. Being still new to the programming world, these routine upgrades are still worrisome to me. I am running apache 2.2.6 (Fedora), PHP 5.1.6 and MySQL 5.0.27 on this server.

  • Is there some standard way to publish a calendar feed?

    - by CMP
    For a web application I am working on, I would like to be able to give the user a single url that they can enter into the calendar application of their choosing to have events from our application show up in their calendar. Most other sites I have seen that do similar things will have a one time download of an .ics file that can be imported. If I have to require my users to download a new file every time the schedule changes, it sort of defeats the purpose of having the feed at all. The calendar can change many many times a day. What I would really like is something like rss where their calendar program can look up a url and automatically see the most recent data. Does anything like this exist? Our main target is mobile devices, so it really should be supported by iCal and google Calendar. Anything else is bonus.

  • Compare Quagga to XORP

    - by Sargun Dhillon
    What do you think of Quagga compared to XORP as a dynamic software routing engine? What are the technical merits of each engine comparatively? Additionally, what do most people think of them from a programming view. Who has manipulated networks using these enginers? I was wondering from an OSPF, routing, BGP protocol user's perpspective.

  • Elaboration of A quotation on 'Simple Design'

    - by HanuAthena
    An excerpt from Programming Perls: A Simple Design : Antonie de Saint-Exupery, the Fresh writer and aircraft designer, said that, *"A designer knows he has arrived at perfection not when there is no longer anything to add, but when there is no longer anything to take away."* More programmers should judge their work by this criteria. Can any one elaborate this, please? What does the author mean when he say "...TAKE AWAY"

  • Where can I find a good software implementation plan template?

    - by Corpsekicker
    This is not "programming" related as much as it is "software engineering" related. I am required to produce an implementation for additional functionality to a complete system. All I am armed with is knowledge of the existing architecture and a functional spec with visual requirements, user stories and use cases. Is there a standardised way to go about this? I suck at documentation.

  • Switch case assembly level code

    - by puffadder
    Hi All, I am programming C on cygwin windows. After having done a bit of C programming and getting comfortable with the language, I wanted to look under the hood and see what the compiler is doing for the code that I write. So I wrote down a code block containing switch case statements and converted them into assembly using: gcc -S foo.c Here is the C source: switch(i) { case 1: { printf("Case 1\n"); break; } case 2: { printf("Case 2\n"); break; } case 3: { printf("Case 3\n"); break; } case 4: { printf("Case 4\n"); break; } case 5: { printf("Case 5\n"); break; } case 6: { printf("Case 6\n"); break; } case 7: { printf("Case 7\n"); break; } case 8: { printf("Case 8\n"); break; } case 9: { printf("Case 9\n"); break; } case 10: { printf("Case 10\n"); break; } default: { printf("Nothing\n"); break; } } Now the resultant assembly for the same is: movl $5, -4(%ebp) cmpl $10, -4(%ebp) ja L13 movl -4(%ebp), %eax sall $2, %eax movl L14(%eax), %eax jmp *%eax .section .rdata,"dr" .align 4 L14: .long L13 .long L3 .long L4 .long L5 .long L6 .long L7 .long L8 .long L9 .long L10 .long L11 .long L12 .text L3: movl $LC0, (%esp) call _printf jmp L2 L4: movl $LC1, (%esp) call _printf jmp L2 L5: movl $LC2, (%esp) call _printf jmp L2 L6: movl $LC3, (%esp) call _printf jmp L2 L7: movl $LC4, (%esp) call _printf jmp L2 L8: movl $LC5, (%esp) call _printf jmp L2 L9: movl $LC6, (%esp) call _printf jmp L2 L10: movl $LC7, (%esp) call _printf jmp L2 L11: movl $LC8, (%esp) call _printf jmp L2 L12: movl $LC9, (%esp) call _printf jmp L2 L13: movl $LC10, (%esp) call _printf L2: Now, in the assembly, the code is first checking the last case (i.e. case 10) first. This is very strange. And then it is copying 'i' into 'eax' and doing things that are beyond me. I have heard that the compiler implements some jump table for switch..case. Is it what this code is doing? Or what is it doing and why? Because in case of less number of cases, the code is pretty similar to that generated for if...else ladder, but when number of cases increases, this unusual-looking implementation is seen. Thanks in advance.

  • Mail.app doesn't see mail changes; requires mailbox "rebuild"

    - by vy32
    I use Mail.app on 4 different computers to access the same mailboxes. I see the same problem on all of them --- if the Mail.app is running, then it catches all of the mail updates. But if a machine is turned off, when it turns back on the mailbox doesn't synchronize properly. I might delete 20 mail messages on one system and they are still on system #2 until I "rebuild." I have seen this happen with the Mobile Me IMAP server, with Gmail, with courier IMAP, and with dovecot. Does anybody else see this? What should I do? Is there a mail server that this happens less with? It's very frustrating, as I get 200-300 mail messages a day and frequently end up handling email messages multiple times.

  • Connecting to localhost with smartphone: possible?

    - by Arturas Molcanovas
    I am currently developing a mobile PHP project on localhost (or, to be more precise, a locally hosted website reachable at http://azgoth/) on my desktop computer and wish to check out how the design looks on my phone's various browsers, however, since the project's actually in my computer rather than the public net, I am unable to do so. Both my Desktop computer and smartphone connect to the internet via the same router, so I wondered, would it be possible to somehow make http://azgoth/ accessible to my smartphone in a similar way that my desktop computer accesses it, without making it public for everyone to see? OS: Windows XP SP 3 Service: Apache HTTPD Router: D-Link DIR-300 FTP Directory

  • Cannot increase my screen resolution

    - by Patrick Beardmore
    I am trying to install my new monitor but my Graphics Adapter (Mobile Intel(R) 915GM/GMS,910GML Express Chipset Family) does not offer a resolution of 1920x1080 in the [Display Properties Settings] window. It only offers up to 1360x768. Can anyone explain to me how I can increase this number to the correct resolution. The monitor does show my the windows desktop, albeit at a lower resolution which is being stretched to fill the screen, making it look very blurry. I have installed the "Monitor Drivers" I found on the disk supplied with new monitor, but these do not appear to have made any difference. The Intel software that comes with the graphics card has an information window containing lots of info about the card and the monitor itself. I have placed this on a webpage so you can examine it if helpful. Many thanks with your help in getting my Christmas present to work! Patrick P.S.: Before I got this screen I checked to see if my graphics card could cope with such a large screen.

  • How to build an outbound load balancer with linux?

    - by matnagel
    We have a small house in the countryside and there is no fixed broadband, so we had a mobile flatrate first, and for 2 people with 2 computers it was too slow, so now we have 2 flatrates for 2 client machines. So I pay 2 flatrates and have double bandwith theoretically. There is a local network in the house that connects everything. But when I am alone I wonder how I can use both connections at the same time. I want to build a solution where I can browse the web and page requests are spread between the 2 connections. I imagine there are expensive routers who can split the traffic between 2 lines. But is there a good way to do it with linux? The solution I am looking for will split the requests already for one page (multiple images, css files, javascrfipt files) between the two lines.

  • How to get a list of all software that starts automatically when Windows 7 starts?

    - by hippietrail
    I know that under Windows there are multiple ways to get an app to autostart but I can never remember what all of those ways are. Is there a single unified way to bring up a list of all programs which are set to run themselves at startup and let me disable those I don't want? I'd prefer something built into Windows. I have Windows 7 Starter. But a free / open source / shareware tool would also be acceptable. (This time the software I want to prevent from autostarting is: MSN Messenger, Y! Messenger, and Vodaphone Mobile Broadband, which starts whether the dongle is inserted or not. None of these three are in Windows's "Startup" folder.)

  • estimating size of reply HTTP headers

    - by Guanidene
    I am trying to download a file via a basic socket connection, using a HTTP GET request. So, I have to specify how many bytes of data coming in I have to read from the socket. However, I am having trouble deciding the amount of data (say, in bytes) the server would reply back with. I know that there is a "Content-Length" field in the reply sent by server, but that gives me the size of the actual data (without the http headers). Is there a way to get the exact size of HTTP headers sent by the server or an estimation is required? (I am doing this for downloading on a mobile network, where every bit of data matters in terms of time and money, so I don't wish to make an unnecessary larger estimate of the header size.)
