  • Is it possible to save output from a command to a file after the command already has been executed?

    - by NES
    Does an elegant way exist to save the output of a command to a file after the command has been run, with the terminal window is open? I mean once the command has been executed in the terminal. The output is still there in terminal. Now i could copy & paste all the lines and save it to a file. But perhaps does a method exist to somehow write the output buffer of a terminal window to a file or even better the output of an already executed command?

  • How can I set 'Print to File' as my default printing option?

    - by edm
    At the moment when I print, my Deskjet-3050 is selected as the default printer. I would like 'Print to File' to be the default 'printer' without using cups-pdf I specifically do not want to use cups-pdf because of the way it renders text (see below). I am not entirely sure what it is doing but it seems as though it renders the text as bitmaps and embeds them in pdf (as I am not able to highlight/copy/search embedded text as I am using a standard Print to File pdf). N.B. this is not a dupe of: Can I make PDF the default for 'print to file'

  • Implementing Qt File Dialog with a Different File System Library (boost)

    - by knight
    Hi, I am writing an application which requires me to use another file system and file engine handlers and not the qt's default ones. Basically what I want to be able to do is to use qt's file dialog but have an underlying file system handler (for example built using boost file system library) of mine handling all the operations with regards to file and directory operations within that dialog. I have already written a custom file engine which handles some of the operations but I am now stuck with Qt's file system model and the file system watcher engine, as I need to have the signals transmitted for this custom file engine. Seems like I have a daunting task ahead. Am I heading in the right direction? Is there any other simpler way that I could implement this? Can anyone give me any idea on how to proceed. I was thinking of looking into proxy models but not sure if that would work. Thanks in advance for any help.

  • Does Django tests run slower on the mac compared to linux?

    - by Thierry Lam
    I'm currently developing my Django projects on both: Mac OS X 10.5, 32 bit Ubuntu Server 9.10 64 bits (1 CPU, 512MB RAM) Both of the above OS are using: Python 2.6.4 Django 1.1.1 MySQL 5.1 Running 12 tests for one of my application take: Mac: 57.513s Linux: 30.935s EDIT: Mac Hardware Spec: MacBook Pro 2.2 GHz Intel Core 2 Duo 3GB RAM I'm running the Ubuntu OS on the same mac above through VMware Fusion 2.0.6. You might argue that Ubuntu Server 64 bits is faster but I have observed a similar speed difference on Ubuntu 8.10 32 bits desktop edition. Even if I turn off my linux VM and other mac applications, I still experience the slowness. Has anyone else experienced this Django test speed difference across those two OS?

  • Threaded Django task doesn't automatically handle transactions or db connections?

    - by Gabriel Hurley
    I've got Django set up to run some recurring tasks in their own threads, and I noticed that they were always leaving behind unfinished database connection processes (pgsql "Idle In Transaction"). I looked through the Postgres logs and found that the transactions weren't being completed (no ROLLBACK). I tried using the various transaction decorators on my functions, no luck. I switched to manual transaction management and did the rollback manually, that worked, but still left the processes as "Idle". So then I called connection.close(), and all is well. But I'm left wondering, why doesn't Django's typical transaction and connection management work for these threaded tasks that are being spawned from the main Django thread?

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

  • Android , Read in binary data and write it to file

    - by Shpongle
    Hi all , Im trying to read in image file from a server , with the code below . It keeps going into the exception. I know the correct number of bytes are being sent as I print them out when received. Im sending the image file from python like so #open the image file and read it into an object imgfile = open (marked_image, 'rb') obj = imgfile.read() #get the no of bytes in the image and convert it to a string bytes = str(len(obj)) #send the number of bytes self.conn.send( bytes + '\n') if self.conn.sendall(obj) == None: imgfile.flush() imgfile.close() print 'Image Sent' else: print 'Error' Here is the android part , this is where I'm having the problem. Any suggestions on the best way to go about receiving the image and writing it to a file ? //read the number of bytes in the image String noOfBytes = in.readLine(); Toast.makeText(this, noOfBytes, 5).show(); byte bytes [] = new byte [Integer.parseInt(noOfBytes)]; //create a file to store the retrieved image File photo = new File(Environment.getExternalStorageDirectory(), "PostKey.jpg"); DataInputStream dis = new DataInputStream(link.getInputStream()); try{ os =new FileOutputStream(photo); byte buf[]=new byte[1024]; int len; while((len=dis.read(buf))>0) os.write(buf,0,len); Toast.makeText(this, "File recieved", 5).show(); os.close(); dis.close(); }catch(IOException e){ Toast.makeText(this, "An IO Error Occured", 5).show(); } EDIT: I still cant seem to get it working. I have been at it since and the result of all my efforts have either resulted in a file that is not the full size or else the app crashing. I know the file is not corrupt before sending server side. As far as I can tell its definitely sending too as the send all method in python sends all or throws an exception in the event of an error and so far it has never thrown an exception. So the client side is messed up . I have to send the file from the server so I cant use the suggestion suggested by Brian .

  • Server-side access to Client Browser's Latitude/Longitude using Django.

    - by ZenGyro
    Hello, So i am writing a little app that compares a user's position against a database on web-based server written using Django and performs some functions with it. Accessing the browser's geolocation data (in supported browsers ) is fairly trivial using JavaScript. But what is the best way to allow the Django server to access the longitude and latitude variables? Is it best to wrap them up as a JSON object and send to the server via POST? Or is there some easier (Geo)Django-based way to access the Navigator.geolocation browser object. Please forgive a newbie a question like this, but my Google-Fuing only seems to find ways to insert variables into JavaScript via template tag, whereas I need it to work the other way! Any advice or code snippets greatly appreciated. Feel free to talk to me like I am an idiot.

  • Python: How can I override one module in a package with a modified version that lives outside the pa

    - by zlovelady
    I would like to update one module in a python package with my own version of the module, with the following conditions: I want my updated module to live outside of the original package (either because I don't have access to the package source, or because I want to keep my local modifications in a separate repo, etc). I want import statements that refer to original package/module to resolve to my local module Here's an example of what I'd like to do using specifics from django, because that's where this problem has arisen for me: Say this is my project structure django/ ... the original, unadulterated django package ... local_django/ conf/ settings.py myproject/ __init__.py myapp/ myfile.py And then in myfile.py # These imports should fetch modules from the original django package from django import models from django.core.urlresolvers import reverse # I would like this following import statement to grab a custom version of settings # that I define in local_django/conf/settings.py from django.conf import settings def foo(): return settings.some_setting Can I do some magic with the __import__ statement in myproject/__init__.py to accomplish this? Is there a more "pythonic" way to achieve this?

  • Django 0.0.0.0:80; can't access remotely

    - by user349555
    Hello, I'm trying to access my Django server from another computer on the same network. I've set up my server and can view everything correctly usingpython manage.py runserver and going to http://127.0.0.1:8000 but when I try to use python manage.py runserver 0.0.0.0:80, I can't view my Django page from another computer. The computer hosting the Django server has intranet IP 192.168.1.146. On my secondary computer, I fire up a browser and try to access http://192.168.1.146:80 to no avail. I've also forwarded port 80 (and I've tried 8000 as well) also to no avail :(. HELP!

  • What file format/database format does Picasa use?

    - by Raymond
    I am trying to figure out what file format the .db file and .pmp files are.

  • robocopy transfer file and not folder

    - by Bill McKay
    I'm trying to use robocopy to tranfer a single file from one location to another but robocopy seems to think I'm always specifying a folder. Here is an example: robocopy "c:\transfer_this.txt" "z:\transferred.txt" But I get this error instead: 2009/08/11 15:21:57 ERROR 123 (0x0000007B) Accessing Source Directory c:\transfer_this.txt\ (note the '\' at the end of transfer_this.txt) But if I treat it like an entire folder: robocopy "c:\folder" "z:\folder" It works but then I have to transfer everything in the folder. How can I only transfer a single file with robocopy?

  • Digital Asset Management, iPhoto / Aperture server... alternative

    - by Sisyphus
    Afternoon, Clients, 10 : All Apples running either Leopard or Snow Leopard Server : Snow Leopard server, (and I have a old Dell Poweredge 650 at home running Gentoo 2.6, if anybody as a Linux solution). The situation: I work in small design company with 8 people, at present we are looking to consolidate all our image files onto one location, at present we each use our preferred single user DAM solution, be it, Adobe Bridge, iPhoto/Aperture (some don't bother at all) The filetypes commonly used are .psd, .pdf, .eps, .tiff, .jpg and RAW image files. Ideally what is needed: Centralised on one server, but allows us to search via spotlight (not essential, but would be nice) Include searchable metadata information such as date, location, title Open-source or as low cost as possibly Allow simultaneous users to import files So far, I have looked at a few open source DAM, systems, such as Razuna, Gallery (not strictly DAM), ResourceSpace, Notre-DAM, while these are brilliant and open-source, they don't integrate as smoothly with the Desktop as iPhoto and aperture. For iPhoto and aperture, I have tried creating a Shared library on the server (a tad laggy), and also using a drive with no permissions, put a library and letting each client read from it, however if they want to put images onto the library only, it's only supports one user at a time writing to the library... Any ideas what could fulfill our needs? Or is it time to bite the bullet for FinalCut Server? Thanks in advance.

  • Free-as-in-beer binary file format inspector

    - by fbrereto
    I am looking for a utility that gives me the ability to specify a binary file format and then interpret a file of bytes according to that format. (Something along the lines of the 010 Editor, but infinitely more cost-effective). Something that runs on Mac OS X would be preferred, but I'm interested to see what all is out there in general (while more of a hassle I'd be willing to run a tool on Windows if it were superior.) What's your preference?

  • Utility to unmap a network drive when the screen saver starts

    - by JimR
    I'm looking for a way to unmap network drives when the screen saver turns on. I have a few users that share an external, encrypted drive (Samba share, not windows) and they have a requirement to disconnect the drive mapping when the local machine is idle. I'd also like it to warn them if there are open files on the mapped drive, if possible. There is also a requirement to force the password to be reentered before mapping when the machine comes back from idle. Is there a Windows setting or utility out there in the wild that meets these requirements?
