  • delayed evaluation of code in subroutines - 5.8 vs. 5.10 and 5.12

    - by Brock
    This bit of code behaves differently under perl 5.8 than it does under perl 5.12: my $badcode = sub { 1 / 0 }; print "Made it past the bad code.\n"; [brock@chase tmp]$ /usr/bin/perl -v This is perl, v5.8.8 built for i486-linux-gnu-thread-multi [brock@chase tmp]$ /usr/bin/perl badcode.pl Illegal division by zero at badcode.pl line 1. [brock@chase tmp]$ /usr/local/bin/perl -v This is perl 5, version 12, subversion 0 (v5.12.0) built for i686-linux [brock@chase tmp]$ /usr/local/bin/perl badcode.pl Made it past the bad code. Under perl 5.10.1, it behaves as it does under 5.12: brock@laptop:/var/tmp$ perl -v This is perl, v5.10.1 (*) built for i486-linux-gnu-thread-multi brock@laptop:/var/tmp$ perl badcode.pl Made it past the bad code. I get the same results with a named subroutine, e.g. sub badcode { 1 / 0 } I don't see anything about this in the perl5100delta pod. Is this an undocumented change? A unintended side effect of some other change? (For the record, I think 5.10 and 5.12 are doing the Right Thing.)

  • Help with Cygwin bash file

    - by Mestika
    Hi, I have a bash file, which I’m trying to run in Cygwin on a Windows 7 platform, but I gives me some odd errors when doing so. The bash file works on my Linux system. The bach file looks like this: for ((r=0; r <10; r++)) netcat localhost 4444 < myfile.file & done wait but I’m getting an error for my for-loop. More precise it writes: ./tuning_test.bsh: line 1: syntax error near unexpected token `(' '/tuning_test.bsh: line 1: `?for ((r=0; r <10; r++)) I do not understand it because I was sure that I’ve a working bash file on my Linux. I even tried to find a for-loop example from a Linux-bash site and run it but with same error. I’m brand new to Cygwin and doesn’t know if it has some small quirks or some other thing I have to be aware of and I’ve tried to look through the documentation and FAQ on their homepage. Sincere Mestika

  • SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); whats that L in the argument for?

    - by ashishsony
    Hi, ive been working on c++ on linux for the past 2 years,and switched to windows c++ programming recently. can anyone tell me what that L is there in the argument of the function: SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); and on viewing certain sample code in MSVS C++ i came across hundereds of typedefs like.. LPARAM// typedef LONG_PTR LPARAM... here LONG_PTR is again typedef as __w64 long WPARAM// typedef UINT_PTR WPARAM... so there is a lot of chained typedefs.. I never saw this much of typedef chaining on c++ programming on linux using gcc.. what i want to say is that it just creates more confusion in this way for windows application programming.. while ive seen application programming on linux using frameworks like Qt.. there such things are rarely used.. so is there specific purpose in typedefining again and again on MSVSC++?? for eg.. there are typdefs like typedef int BOOL; whats the use of this when normal bool is available already..?? there are hundred other cases ive come across where just to decide what data type to use becomes so difficult.. it becomes difficult to understand a pre written code in this fashion too.. Thanks.

  • How to move the Windows 7 bootloader to the Windows 7 partition?

    - by pauldoo
    I recently installed Windows 7 in a triple boot setup alongside XP and Linux. When I was finished and was in the process of restoring the bootloader for Linux I discovered something strange about what Windows 7 had done. I discovered that Windows 7 had not installed a bootloader to it's own partition, and instead had instead set up a bootloader on the pre-existing XP partition that offers a choice between 7 and XP. This behaviour has been noticed by others. Now my booting is slightly odd. I have GRUB on the MBR which lets me choose between Linux and Windows. When I select Windows I have Grub boot to the XP partition where I get the 2nd choice between 7 and XP. Why doesn't the Windows 7 installer put the Windows 7 bootloader on the Windows 7 partition like all previous MS OSs? This is now going to be a real problem for me, as I now want to wipe the XP partition and install something else there (probably another non-MS OS). How can I move the bootloader for Windows 7 onto the Windows 7 partition, thus making it bootable and allowing me to safely wipe the XP partition?

  • Does HttpListener work well on Mono?

    - by billpg
    Hi everyone. I'm looking to write a small web service to run on a small Linux box. I prefer to code in C#, so I'm looking to use Mono. I don't want the overhead of running a full web server or Mono's version of ASP.NET. I'm thinking of having a single process with a thread dealing with each client connection. Shared memory between threads instead of a database. I've read a little on Microsoft's version of HttpListener and how it works with the Http.sys driver. Alas, Mono's documentation on this class is just the automated class interface with no discussion of how it works under the hood. (Linux doesn't have Http.sys, so I imagine it's implemented substantially differently.) Could anyone point me towards some resources discussing this module please? Many thanks, Bill, billpg.com (A little background to my question for the interested.) Some time ago, I asked this question, interested in keeping a long conversation open with lots of back-and-forth. I had settled on designing my own ad-hoc protocol, but people I spoke to really wanted a REST interface, even at the cost of the "Okay, send your command now" signal. So, I wondered about running ASP.NET on a Linux/Mono server, but stumbled upon HttpListener. This seemed ideal, as each "conversation" could run in a separate thread. The thread that calls HttpListener in a loop can look for which thread each incomming connection is for and pass the reference to that thread. The alternative for an ASP.NET driven service, would be to have the ASPX code pick up the state from a database, and write back the new state when it finishes. Yes, it would work, but that's a lot of overhead.

  • Parse and read data frame in C?

    - by user253656
    I am writing a program that reads the data from the serial port on Linux. The data are sent by another device with the following frame format: |start | Command | Data | CRC | End | |0x02 | 0x41 | (0-127 octets) | | 0x03| ---------------------------------------------------- The Data field contains 127 octets as shown and octet 1,2 contains one type of data; octet 3,4 contains another data. I need to get these data I know how to write and read data to and from a serial port in Linux, but it is just to write and read a simple string (like "ABD") My issue is that I do not know how to parse the data frame formatted as above so that I can: get the data in octet 1,2 in the Data field get the data in octet 3,4 in the Data field get the value in CRC field to check the consistency of the data Here the sample snip code that read and write a simple string from and to a serial port in Linux: int writeport(int fd, char *chars) { int len = strlen(chars); chars[len] = 0x0d; // stick a <CR> after the command chars[len+1] = 0x00; // terminate the string properly int n = write(fd, chars, strlen(chars)); if (n < 0) { fputs("write failed!\n", stderr); return 0; } return 1; } int readport(int fd, char *result) { int iIn = read(fd, result, 254); result[iIn-1] = 0x00; if (iIn < 0) { if (errno == EAGAIN) { printf("SERIAL EAGAIN ERROR\n"); return 0; } else { printf("SERIAL read error %d %s\n", errno, strerror(errno)); return 0; } } return 1; } Does anyone please have some ideas? Thanks all.

  • GCC Dynamic library building problem

    - by Sirish Kumar
    I am new to linux, while compiling with dynamic library I am getting the segmentationfault error. I have two files ctest1.c void ctest1(int *i) { *i =10; } ctest2.c void ctest2(int *i) { *i =20; } I have compiled both files to a shared library named libtest.so using following command gcc -shared -W1,-soname,libtest.so.1 -o libtest.so.1.0.1 ctest1.o ctest2.o -lc And I have wrote another program prog.c which uses functions exported by this library prog.c #include void (ctest1)(int); void (ctest2)(int*); int main() { int a; ctest1(&a); printf("%d",a); return 0; } And when I have built the executable with following command gcc -Wall prog.c -L. -o prog But when I run the generated executable I get the SegmentationFault error. When I checked the header of prog with ldd it shows linux-vdso.so.1 = (0x00007f99dff000) libc.so.6 = /lib64/libc.so.6 (0x0007feeaa8c1000) /lib64/ld-linux-x86-64.so.2 (0x00007feeaac1c000) Can somebody tell what is the problem

  • How can get dtrace to run the traced command with non-root priviledges ?

    - by Gyom
    OS X lacks linux's strace, but it has dtrace which is supposed to be so much better. However, I miss the ability to do simple tracing on individual commands. For example, on linux I can write strace -f gcc hello.c to caputre all system calls, which gives me the list of all the filenames needed by the compiler to compile my program (the excellent memoize script is built upon this trick) I want to port memoize on the mac, so I need some kind of strace. What I actually need is the list of files gcc reads and writes into, so what I need is more of a truss. Sure enough can I say dtruss -f gcc hello.c and get somewhat the same functionality, but then the compiler is run with root priviledges, which is obviously undesirable (apart from the massive security risk, one issue is that the a.out file is now owned by root :-) I then tried dtruss -f sudo -u myusername gcc hello.c, but this feels a bit wrong, and does not work anyway (I get no a.out file at all this time, not sure why) All that long story tries to motivate my original question: how do I get dtrace to run my command with normal user priviledges, just like strace does in linux ? Edit: is seems that I'm not the only one wondering how to do this: question #1204256 is pretty much the same as mine (and has the same suboptimal sudo answer :-)

  • HTTP Negotiate windows vs. Unix server implementation using python-kerberos

    - by ondra
    I tried to implement a simple single-sign-on in my python web server. I have used the python-kerberos package which works nicely. I have tested it from my Linux box (authenticating against active directory) and it was without problem. However, when I tried to authenticate using Firefox from Windows machine (no special setup, just having the user logged into the domain + added my server into negotiate-auth.trusted-uris), it doesn't work. I have looked at what is sent and it doesn't even resemble the things the Linux machine sends. This Microsoft description of the process pretty much resembles the way my interaction from Linux works, but the Windows machine generally sends a very short string, which doesn't even resemble the things microsoft documentation states, and when base64 decoded, it is something like 12 zero bytes followed by 3 or 4 non-zero bytes (GSS functions then return that it doesn't support such scheme) Either there is something wrong with the client Firefox settings, or there is some protocol which I am supposed to follow for the Negotiate protocol, but which I cannot find any reference anywhere. Any ideas what's wrong? Do you have any idea what protocol I should by trying to find, as it doesn' look like SPNEGO, at least from MS documentation.

  • Get filename from path

  • Cross Platform C library for GUI Apps?

    - by Moshe
    Free of charge, simple to learn/use, Cross Platform C library for GUI Apps? Am I looking for Qt? Bonus question: Can I develop with the said library/toolkit on Mac then recompile on PC/Linux? Super Bonus Question: Link to tutorial and/or download of said library. (RE)EDIT: The truth is that I'm in the process of catching up on the C family (coming from web development - XHTML/PHP/MySQL) to learn iPhone development. I do understand that C is not C++ or ObjectiveC but I want to keep the learning curve as simple as possible. Not to get too off topic, but I am also on the lookout for good starter books and websites. I've found this so far. I'm trying to kill many birds with one stone here. I don understand that there are platform specific extensions, but I will try to avoid those for porting purposes The idea is that I want to write the code on one machine and just compile thrice. (Mac/Win/Linux) If Objective C will compile on Windows and Linux as well as OS X then that's good. If I must use C++, that's also fine. EDIT: Link to QT Please...

  • Getting Google repositories to work with apt-get on Ubuntu Hardy

    - by Justin
    I've installed Google Chrome on Hardy via the .deb file and would like to configure apt-get for automatic updates. [I have another machine running Ubuntu Karmic where this works fine; apt-get knows the package as 'google-chrome'; I'm now using a Dell Mini 10 with Ubuntu 8.04 LTS installed] As part of the .deb install, two entries have been added to the third- party software sources tab: http://dl.google.com/linux/deb stable main http://dl.google.com/linux/deb stable non-free main However if I check for updates with either of these clicked, I get the following error: Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release Unable to find expected entry main/binary-lpia/Packages in Meta-index file (malformed Release file?) There is a thread here which indicates others have had the same problem: http://www.google.co.uk/support/forum/p/Chrome/thread?tid=097d103f87b49abe&hl=en This references a further thread: http://code.google.com/p/chromium/issues/detail?id=38608 which suggests the problem has been fixed. Despite this I remain unable to get it to work, and none of the suggested workarounds seem to work either. Ideas ? Thanks.

This way, I could install Visual Studio and be able to work seamlessly. But, this way of working has a major down side: it kills the battery of my laptop… I can easiely last for 3 hours if I stay in OS X, but can only last 45 min when XP is running. Recently, I gave MonoDevelop a try for developing Developer IT‘s tools and web site. While being way less complete then Visual Studio, it provides essentials tools when it comes to developping software. It works well with solutions and projects files created from Visual Studio, it has Intellisence (word completion), it can compile your code and can even target your .NET app to linux or unix. This tools can save me a lot of time and batteries! Although I could not only work with MonoDevelop, I find it way better than a simple text editor like Smultron. Thanks to Novell, we can now bring Microsoft technology to OS X.

  • Need a solution to store images (1 billion, 1000,000,000) which users will upload to a website via php or javascript upload [on hold]

    - by wish_you_all_peace
    I need a solution to store images (1 billion) which users will upload to a website via PHP or Javascript upload (website will have 1 billion page views a month using Linux Debian distros) assuming 20 photos per user maximum (10 thumbnails of size 90px by 90px and 10 large, script resized images of having maximum width 500px or maximum height 500px depending on shape of image, meaning square, rectangle, horizontal, vertical etc). Assume this to be a LEMP-stack (Linux Nginx MySQL PHP) social-media or social-matchmaking type application whose content will be text and images. Since everyone knows storing tons of images (website users uploaded images in this case) are bad inside a single directory or NFS etc, please explain all the details about the architecture and configuration of the entire setup of storage solution, to store 1 billion images on any method you recommend (no third-party cloud storage like S3 etc. It has to be within the private data center using our own hardware and resources.). The solution has to include both the storage solution and organizing the images uploaded by users. How will we organize the users images if a single user will not have more than 20 images (10 thumbs and 10 large of having either width or height 500px)? Please consider that this has to be organized in a structural way so we can fetch a single user's images via PHP/Javascript or API programmatically through some type of user's unique identifier(s).

  • Enabling SFTP Access within PLESK

    - by spelley
    Hello everyone, I have a client who wants to ensure his upload is secure, so we are trying to enable SFTP for him on our Linux PLESK server. I have enabled SSH access to bin/bash for FTP accounts, and created a new user. When I attempt to SFTP using either the IP address or the domain name, this is the error FileZilla is giving me: Error: Authentication failed. Error: Critical error Error: Could not connect to server Here is some basic information regarding the server: Operating system Linux 2.6.24.5-20080421a Plesk Control Panel version psa v8.6.0_build86080930.03 os_CentOS 5 I had read in some places that I should reboot the SSH Service in Server - Services, however, there is no SSH Service within the list. I'm not really a server guy so it's quite possible I'm missing something obvious. Thanks for any help that you guys can provide!

  • Speaker at developer conferences and user group meetings

    Catching up on a couple of sessions I did in the past. This article gives an overview of some of my activities. Mainly at the annual German Visual FoxPro Developer Conference also known as SQL-Server & ASP.NET Conference in Frankfurt. The below listed entries are excerpts from the original Conference Coverage documents you'll find on UniversalThread. German Visual FoxPro Developer Conference 2002 (1 session - Vendor session about Active FoxPro Pages 3.0) German Visual FoxPro Developer Conference 2003 (2.5 sessions - Visual FoxPro running on Linux) German Visual FoxPro Developer Conference 2004 (4 sessions - 2x Active FoxPro Pages, VFP on Linux, and VFP using additional databases) German Visual FoxPro Developer Conference 2005 (4 sessions - RegEx, XML, XSLT, and using free (as in beer) development tools) German Visual FoxPro Developer Conference 2006 (3 sessions - .NET interop via COM, writing own CLR host in VFP, and Active FoxPro Pages) Furthermore, I did a couple of (hopefully) interesting sessions at various user group meetings in Speyer and Stuttgart. A more comprehensive list is available under Presentations (in German language). And last but not least, back in May 2005 Microsoft Germany invited me to host a WebCast for MSDN on how to use 'Visual FoxPro mit Visual Studio 2005'. Unfortunately, I was too unexperienced and too nervous (first time ever), we experienced technical issues with the microphone, and the obviously low quality of recording demanded to replace it by a whole series on Visual FoxPro 9.0. The webcast covered the same topics I already described in other articles here on my blog. Despite the desaster I'd like to thank Ralf Westphal for his kind words afterwards - I really felt bad. Eventually, you might ask yourself why it stopped by the end of 2006... Well, new chapter in my life: Mauritius!

  • How would you apply a BIOS update for a Dell M610 blade with VMware ESXi installed?

    - by Guamaniac
    Hello, all. We've got a Dell M610 blade with VMware ESXi 4 installed and we need to update it's BIOS to the latest version. Unfortunately, Dell only makes available a Windows (.exe) and Linux (.bin) versions of the BIOS update program (as well as a bootable DOS floppy version that is too big to fit on a 1.44MB floppy!). We've tried using various "LiveCD" versions of linux distributions but keep running into errors. Anyone out there with experience with Dell blades who could give us a hint or two to get this working? Thanks a lot, in advance. Joe

  • fastcgi-mono-server2 vs fastcgi-mono-server4

    - by Phill
    Not sure if this is a silly question or not. Basically I'm figuring out how to run Mono on Linux, and I'm a Linux no0b. I've got everything up and running, but confused about fastcgi-mono-server. A lot of sites reference fastcgi-mono-server2 while other sites reference fastcgi-mono-server4 When I run: fastcgi-mono-server /version fastcgi-mono-server2.exe 2.10.0.0 I get the same version number for both. If I look at the Mono version Mono JIT compiler version 2.10.8.1 I'm wondering if the version on the mono-server corresponds to the mono version, and not the mono-server version. Is fastcgi-mono-server4 just a newer version?
