  • "Hello World" in less than 20 bytes

    - by xelurg
    We have had an interesting competition once, where everyone would write their implementation of hello world program. One requirement was that is should be less than 20 bytes in compiled form. the winner would be the one whose version is the smallest... What would be your solution? :) Platform: 32bit, x86 OS: DOS, Win, GNU/Linux, *BSD Language: Asm, C, or anything else that compiles into binary executable (i.e. no bash scripts and stuff ;)

  • Tool to monitor HTTP traffic

    - by Samuh
    I have an application on my iPhone which sends out Http requests; is it possible to look into the HTTP stream using some tool?? I use standalone version of (IEInspector's) HttpAnalyzer tool on my windows PC to monitor HTTP traffic from all processes including the apps on Android phone (thanks to android debug bridge interface). Is there a similar tool for OS X that I can use for iPhone apps? Is this even allowed? Thanks in advance.

  • tmpfile and gzip combination problem

    - by Vojtech R.
    I have problem with this code: file = tempfile.TemporaryFile(mode='wrb') file.write(base64.b64decode(data)) file.flush() os.fsync(file) # file.seek(0) f = gzip.GzipFile(mode='rb', fileobj=file) print f.read() I dont know why it doesn't print out anything. If I uncomment file.seek then error occurs: File "/usr/lib/python2.5/gzip.py", line 263, in _read self._read_gzip_header() File "/usr/lib/python2.5/gzip.py", line 162, in _read_gzip_header magic = self.fileobj.read(2) IOError: [Errno 9] Bad file descriptor Just for information this version works fine: x = open("test.gzip", 'wb') x.write(base64.b64decode(data)) x.close() f = gzip.GzipFile('test.gzip', 'rb') print f.read()

  • Automated regression tests for java applets?

    - by Roy Tang
    We're working on a project with a number of applets that has to work across a large range of OS (WIndows, Mac, Linux), browsers (IE, FF, Safari, etc) and Java versions (1.5+), and it often happens that a fix we apply will cause some sort of security exception an another platform or some other error. Is there any way for us to prepare automated tests to immediately catch those problems in different platforms? I think it's not necessary to check that the gui parts are appearing as intended, but just to detect whether unexpected exceptions are occuring.

  • Learning to create beautiful /next-generation GUI

    - by ShaChris23
    I really want to create a stunning-looking GUI desktop application that looks like, for example: Mac OS X interface Picasa desktop client on windows IPhone apps Office 2007 I've mostly been programming GUI using Qt/Swing/WinForm and I'm tired of creating so plain looking GUI, lol. So I was thinking about diving into stuff like: jQuery WPF/C# iPhone SDK Silverlight Adobe Air/Flex Just to get some ideas on how to create really cool looking UI. Does that sound like a good list? Any developers here that could share what platform they use to create very cool looking desktop app? On a sidenote, I really wonder what developers at Apple / Microsoft use to develop their own cool-looking software. EDIT A lot of responses talk about the importance of usability over "cool-looking".. I totally agree that usability and simplicity are the most important aspects of user interface design. I've been doing GUI development for a while now ( 3 years), so that I understand. But using cool-looking UI also improves user experience + it could make big difference on whether or not your software sells. I mean, otherwise why would Microsoft/Apple try to make their OS UI look "cooler" everytime there's a new version? Why would websites like pragprog.com, or versionsapp.com. make their websites look like that? Basically you kill 2 birds with one stone: stunnning-looking UI + super usability (because it looks simple and intuitive). That is what I'm striving for. And as far as I know, I cannot achieve that using Qt/Winform. Most of the books I have read just show you how to make average-looking (read: 1990's) UI. I want to learn how to create cool-looking UI. And the only place I see cool-looking UIs these days are the technology I list above. I'm not enamored with any technology; but I just want to know how things are done in other technology to see if I could apply them to the technology I'm using, or see if I could use those technology in my line of work. An example: if I were to pick between this UI and this UI, I probably would pick the latter, if just based on looks alone. Functionally, they are just the same UI; they both allow you to keep track of your time. They both contain buttons and textboxes, etc. But the fact that they look different, also differentiate them in terms of attractiveness. So in all, I think the "ice on the cake" is very important. I would say it's the thing you strive for after you are certain you have a totally intuitive, usable UI.

  • What is the best practices for checking if the user of a Python script has root-like privileges?

    - by Paul Hoffman
    I have a Python script that will be doing a lot of things that would require root-level privileges, such as moving files in /etc, installing with apt-get, and so on. I currently have: if os.geteuid() != 0: exit("You need to have root privileges to run this script.\nPlease try again, this time using 'sudo'. Exiting.") Is this the best way to do the check? Are there other best practices?

  • Executing Javascript without a browser?

    - by Daniel
    I am looking into Javascript programming without a browser. I want to run scripts from the Linux or Mac OS X command line, much like we run any other scripting language (ruby, php, perl, python...) $ javascript my_javascript_code.js I looked into spider monkey (Mozilla) and v8 (Google), but both of these appear to be embedded. Is anyone using Javascript as a scripting language to be executed from the command line? If anyone is curious why I am looking into this, I've been poking around node.js

  • Virtualenv with Eclipse (Galileo)

    - by Adam Nelson
    Does anybody have directions for getting Eclipse (Galileo), PyDev, and Virtualenv working together? I'm specifically trying to run Pinax but any instructions are fine. I thought I had it (and even blogged everything but the final step - interactive debugging) and still there is no solution. I'm specifically on OS X but any answer should be sufficient. This is the best resource I've found so far: http://blog.vlku.com/index.php/2009/06/10/djangoeclipse-with-code-complete-screencast/

  • IPython doesn't work in Django shell

    - by Zemogle
    I've just recently switched over to using 64-bit Python 2.6.1 on Mac OS X 10.6 (Snow Leopard). IPython won't work with Django anymore, but IPython works from the command-line. The error says: shell = IPython.Shell.IPShell(argv=[]) AttributeError: 'module' object has no attribute 'Shell' I could use the ./manage.py --plain option, but it's not really a fix. Any help very gratefully received!

  • Python3 - Deleting dirs after finishing a commando prompt

    - by user302935
    I have a python script that ends with running a program (iexpress.exe) in a dos prompt. The program that runs in dos prompt, uses a dir called workdir. After the program has finished in the dos prompt I would like python to delete the dir. I have just made a simple solution of putting a delay of 30sec: time.sleep(30) removeall(workdir) os.rmdir(workdir) But how should I do it, if python should delete the dir right after the process has finished?

  • Can a memory page be moved by modifying the page table?

    - by Adam
    Is it possible (on any reasonable OS, preferably Linux) to swap the contents of two memory pages by only modifying the page table and not actually moving any data? The motivation is a dense matrix transpose. If the data were blocked by page size it would be possible to transpose the data within a page (fits in cache) then swap pages to move the blocks into their final place. A large matrix would have many many pages moved, so hopefully flushing the TLB wouldn't cause trouble.
