  • UML or design tools for websites

    - by Malfist
    What is a good tool to design the implementation of websites? I typically use UMl to design applications, but I feel that does not apply well to websites, specifically the heavy emphasis on UI that websites require. What would be a good tool to use to plan a webpage?

  • how to bind a link local address to an ipv6 socket

    - by Haiyuan Zhang
    This thread can be treated as a sister thread of this. It's will be very tedious that when you want to bind a link local adress to a ipv6 socket you need to the set sin6_scope_id field of sockaddr_in6 struct as well. I'm wondering if someone can provide a good practise like solution here for me or anyone who interested in this topic to learn from.

  • Allow outgoing connections using 'iptables'

    - by umanga
    Greeting all, "iptables -L" gives the following output [root@ibmd ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Server has global IP and can be accessed from outer IPs.But I cannot ping nor telnet to any port (including TCP 80) from the server. Does this has something to do with my 'iptables' settings ? Any tips on allow access from my server? thanks in advance.

  • How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

    - by Michael Gundlach
    I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via :inoremap <C-H> <C-W> but in gnome-terminal I cannot figure out a way to make it happen. When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately, :inoremap <C-?> <C-W> doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what. Regarding ASCII codes: Gnome-terminal lets you change the backspace character under Edit - Profile Preferences - Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like :inoremap <C-H> <C-W> then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like :inoremap <C-^H> <C-W> then regular backspace and control-backspace just erase a single character.

  • Query size of block device file in Python

    - by ??O?????
    Hello. I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device size) remains, and it's not answered here, so I open this question. I am aware of the following two related SO questions: Determine the size of a block device (/proc/partitions, ioctl through ctypes) how to check file size in python? (about non-special files) Therefore, I'm asking: in Python, how can I get the file size of a block device file?

  • Ajax based progress bar

    - by Punit
    I am developing a progress bar using Ajax. My client side code is working fine, but I have issue at server side. I am using C based CGI. if(i == inc && pb_inc<=100) { fptr = fopen("progress_bar.txt", "w"); fprintf(fptr,"%d", j); fclose(fptr); pb_inc++; } basically I am increasing progress bar after certain number of bytes. What I see here is that the CGI doesn't let display any data to text file until it has sent all the data to file one by one. i have referred to http://www.redips.net/javascript/ajax-progress-bar/ Any idea whats happening here?

  • Operation is not valid due to the current state of the object

    - by DBa
    Sometimes, when running a Mono .NET application (it seems to not depend on the input data, as it does not change), I run into following situation: when trying to Dequeue an element from a (non-empty, I check its Count beforehand) Queue, an exception is thrown: Unhandled Exception: System.InvalidOperationException: Operation is not valid due to the current state of the object at System.Collections.Generic.Queue1[DBWorkItem].Peek ()[0x00000] at System.Collections.Generic.Queue1[DBWorkItem].Dequeue () [0x00000] at DBProcessor.process (System.Object q) [0x0006b] in <... Though I can certainly catch this exception, the element is dequeued and lost. Has anyone else encountered this behavior, too?

  • Looking for regex to extract email addresses from /etc/passwd

    - by Brent
    Most of my users have email addresses associated with their profile in /etc/passwd. They are always in the 5th field, which I can grab, but they appear at different places within a comma-separated list in the 5th field. Can somebody give me a regex to grab just the email address (delimeted by commas) from a line in this file? (I will be using grep and sed from a bash script) Sample lines from file: user1:x:1147:5005:User One,Department,,,[email protected]:/home/directory:/bin/bash user2:x:1148:5002:User Two,Department2,[email protected],:/home/directory:/bin/bash

  • Other users on my Server?

    - by Jennifer Weinberg
    I'm buying a Server from a person (that I don't know really well) and I want to make sure that the previous owner hasn't got any access anymore. It's an Ubuntu Virtual Server and I already received the admin access (via shell). How can I find out if there are still other accounts left, who are still able to access my server (e.g. with a still existing shell account, ftp or another type of user account)? And how can I delete them if these accounts exist? Best regards, Jennifer

  • Running resize2fs on /

    - by Paul Steckler
    I'm trying to resize an ext4 filesystem on a Fedora 11 box. Using fsdisk and lvm, I was able to grow the partition and logical volume containing the filesystem. When I try to run resize2fs on the device containing the filesystem (/dev/sda2 in this case), I get: "Device or resource busy while trying to open /dev/sda2, Couldn't find valid filesystem superblock" I've tried this from a rescue disk that doesn't have the filesystem mounted, no joy. Maybe resize2fs doesn't know about ext4?

  • Email pipe to php script working only sometimes

    - by Rixius
    I have a php pipe script that takes an attached *.csv from an email and saves and parses it. When the email is sent from where it is supposed to be coming from, it silently errors, however, when I take that same email and resend it from my address it goes through just fine. is there any simple reason it could be doing this?

  • PHP Segmentation fault when started from crond

    - by Jeroen Moors
    Hello, I've a php script that's started each minute from cron. It almost always runs without any problem, except for about 10 times within 24h. The times it fails I get a segmentation fault like: bin/sh: line 1: 21815 Segmentation fault /usr/bin/myscript The number after "line 1:" is always different. I'm running: PHP 5.2.6-1+lenny8 with Suhosin-Patch 0.9.6.2 (cli) (built: Mar 14 2010 08:14:04) Is this a problem with my version of PHP? Is there a way to debug this? I have the feeling it crashes when the server load is high, but there's absolutely no prove for this. Any feedback is welcome!

  • error loading (TypeLoadException) on asp.net/xsp/mono on debian/opensuse

    - by acidzombie24
    When i reset apache and load my website i get the first error below. I have no idea what the problem is. If i reload the page again (without restarting apache) i get the 2nd error, probably because the first error occurred and BaseUser is the first class/func that Application_Start uses. Why am i getting this load exception? Whats messed up is i tried using mono's VMWare img to debug it and i got the very same exception (until i restarted which now refuses to give me anything but 404 errors). However when i use mono develop to run the project the site runs PERFECT. WTF. Any ideas? Server Error in '/' Application A type load exception has occurred. Description: HTTP 500. Error processing request.

  • What is the effect of running an application with "Unlimited Stack" size

    - by NSA
    Hello All, I have inherited some code that I need to maintain that can be less than stable at times. The previous people are no longer available to query as to why they ran the application in an environment with unlimited stack set, I am curious what the effects of this could be? The application seems to have some unpredictable memory bugs that we cannot find and running the application under valgrind is not an option because it slows the application down so much that we cannot actually run it. So any thoughts on what the effects of this might be are appreciated. Thank you.
