• How to generate a unique hash for a URL ?

  - by Jacques René Mesrine

  Given these two images from twitter. http://a3.twimg.com/profile_images/130500759/lowres_profilepic.jpg http://a1.twimg.com/profile_images/58079916/lowres_profilepic.jpg I want to download them to local filesystem & store them in a single directory. How shall I overcome name conflicts ? In the example above, I cannot store them as *lowres_profilepic.jpg*. My design idea is treat the URLs as opaque strings except for the last segment. What algorithms (implemented as f) can I use to hash the prefixes into unique strings. f( "http://a3.twimg.com/profile_images/130500759/" ) = 6tgjsdjfjdhgf f( "http://a1.twimg.com/profile_images/58079916/" ) = iuhd87ysdfhdk That way, I can save the files as:- 6tgjsdjfjdhgf_lowres_profilepic.jpg iuhd87ysdfhdk_lowres_profilepic.jpg I don't want a cryptographic algorithm as it this needs to be a performant operation.

• Apps not showing in Django admin site

  - by jack

  I have a Django project with about 10 apps in it. But the admin interface only shows Auth and Site models which are part of Django distribution. Yes, the admin interface is up and working but none of my self-written apps shows there. INSTALLED_APPS INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.sites', 'django.contrib.contenttypes', 'django.contrib.humanize', 'django.contrib.sessions', 'django.contrib.admin', 'django.contrib.admindocs', 'project.app1', ... app1/admin.py from django.contrib import admin from project.app1.models import * admin.site.register(model1) admin.site.register(model2) admin.site.register(model3) What could be wrong in this case? Looks like everything is configured as what document says. Thank you in advance.

• Drupal Migration Problem

  - by Gok Demir

  After migrating my Drupal (6.16) installation from shared hosting to Linode VPS (Ubunto 10.04 32 bit). Whenever I click a URL it shows only the homepage. I put ?q=user at the end of the URL to login as an admin. When I logged in it is the same. I couldn't navigate to any URL. It shows only homepage. I forgot to clean Drupal cache before migration. Is it because of this? I couldn't navigate to Administer Site configuration Performance to clean cache, nothing works.

• OpenCV 2.0 and Python

  - by Jive Dadson

  I cannot get the example Python programs to run. When executing the Python command "from opencv import cv" I get the message "ImportError: No module named _cv". There is a stale _cv.pyd in the site-packages directory, but no _cv.py anywhere. See step 5 below. MS Windows XP, VC++ 2008, Python 2.6, OpenCV 2.0 Here's what I have done. Downloaded and ran the MS Windows installer for OpenCV2.0. Downloaded and installed CMake Downloaded and installed SWIG Ran CMake. After unchecking "ENABLE_OPENMP" in the CMake GUI, I was able to build OpenCV using INSTALL.vcproj and BUILD_ALL.vcproj. I do not know what the difference is, so I built everything under both of those project files. The C example programs run fine. Copied contents of OpenCV2.0/Python2.6/lib/site-packages to my installed Python2.6/lib/site-packages directory. I notice that it contains an old _cv.pyd and an old libcv.dll.a.

• SyntaxError using gdata-python-client to access Google Book Search Data API

• What's a good Minimal Server-Side Javascript Framework?

  - by Nick Retallack

  So I was writing a web app with web.py that uses plenty of client-side javascript, and my database is on couchdb so the queries are in javascript too, and eventually I just got to thinking, why not skip the python and go all javascript? Besides, some functions need to run once on the client and again on the server to make sure you're not spoofing, so why translate between javascript and python? So I'm looking for a simple lightweight javascript web framework. All I really need is the url routing, request and response stuff (standard wsgi?), and a way to hook into a big http server like nginx. What do you guys recommend?

• Loading fixtures in django unit tests

  - by loder

  I'm trying to start writing unit tests for django and I'm having some questions about fixtures: I made a fixture of my whole project db (not certain application) and I want to load it for each test, because it looks like loading only the fixture for certain app won't be enough. I'd like to have the fixture stored in /proj_folder/fixtures/proj_fixture.json. I've set the FIXTURE_DIRS = ('/fixtures/',) in my settings.py. Then in my testcase I'm trying fixtures = ['proj_fixture.json'] but my fixtures don't load. How can this be solved? How to add the place for searching fixtures? In general, is it ok to load the fixture for the whole test_db for each test in each app (if it's quite small)? Thanks!

• Rewriting An URL With Regular Expression Substitution in Routes

  - by Sean M

  In my Pylons app, some content is located at URLs that look like http://mysite/data/31415. Users can go to that URL directly, or search for "31415" via the search page. My constraints, however, mean that http://mysite/data/000031415 should go to the same page as the above, as should searches for "0000000000031415." Can I strip leading zeroes from that string in Routes itself, or do I need to do that substitution in the controller file? If it's possible to do it in routing.py, I'd rather do it there - but I can't quite figure it out from the documentation that I'm reading.

• Trying to add trailing slash with htaccess, results in a absolute path

  - by Fredrik

  What I'm trying to achive is to have all urls on my page look like http://domain.com/page/, no extensions, but a trailing slash. If a user happends to write http://domain.com/page or http://domain.com/page.php it will redirect to the first url. After some googling i found this code, and it's close to working, but when you leave out the trailing slash in your request the url becomes something like http://domain.com/Users/"..."/page/ and therefor returns a 404. My .htaccess looks like this: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php RewriteRule (.*)\.php$ /$1/ [L,R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteRule (.*)/$ $1.php [L] RewriteCond %{REQUEST_FILENAME} !(.*)/$ RewriteRule (.*)/$ $1.php [L] RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule .*[^/]$ $0/ [L,R=301] I've been trying to add an additional rule but I really don't get any of this and I haven't been able to find any answers.

• Any way to view dynamic java content ex-post? Browser session still open

  - by Ryan

  I feel like a grandpa from 1996 asking this, but is it at all possible to view a representation of a particular screen that was rendered as part of a java-based online checkout process I executed a couple days ago? I haven't cleared my browser cache or temp files or anything, and I don't think I've restarted the comp or even the browser since. I'm using mac OS X 10.6.8, and the page(s) were viewed with Chrome version 21.0.1180.89 in standard mode (not incognito). Specifically the page in question was part of Verizon Wireless's 'iconic' contract/checkout process, which leads the user through several pages to make selections on various criteria and seems to be based on java. (Obviously I'm a dummy regarding web stuff so the question is probably not very well defined, I'm happy to elaborate). ^This is the tl;dr question. If it belongs on another site please just let me know. This is what I've been able to figure out on my own, for the bored / ultra-helpful / those who could use a laugh at a noob fumbling his way around cache files with no idea what he's doing: The progress through the selection pages is very clear in Chrome's browser history, the sequential pages are: https://www.verizonwireless.com/b2c/accountholder/estore/phoneupgrade?execution=e3s2 https://www.verizonwireless.com/b2c/accountholder/estore/phoneupgrade?execution=e3s3 https://www.verizonwireless.com/b2c/accountholder/estore/phoneupgrade?execution=e3s4 https://www.verizonwireless.com/b2c/accountholder/estore/phoneupgrade?execution=e3s5 https://preorder.verizonwireless.com/iconic/?format=JSON&value={%22action%22:%22START_ORDER%22,%22custType%22:%22EXISTING%22,%22orderType%22:%22UPGRADE%22,%22lookupMtn%22:%22*(NumberA)*%22,%22lineData%22:[{%22mtn%22:%22*(NumberA)*%22,%22upgType%22:%22ALTERNATE_UPGRADE%22,%22eligibleMtn%22:%22*(NumberB)*%22}]} https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicOrder.do?format=JSON&value={%22action%22:%22START_ORDER%22,%22custType%22:%22EXISTING%22,%22orderType%22:%22UPGRADE%22,%22lookupMtn%22:%22*(NumberA)*%22,%22lineData%22:[{%22mtn%22:%22*(NumberA)*%22,%22upgType%22:%22ALTERNATE_UPGRADE%22,%22eligibleMtn%22:%22*(NumberB)*%22}]} https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicEligibility.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicDeviceSelection.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/PlanOptions.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicFeatures.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicAccessories.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicShipmentBilling.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicReview.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicPaymentCreditInfo.do https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicConfirmation.do The visual representation I would need could come from any of these pages, as the necessary information was shown at the top of each of them (although the two with long URLs were just like redirects or something). Of course, clicking the link to the page in History right now requires a new sign-in and just returns the user to the initial step for doing the process again; it does not pull up a representation of the page as it was seen several days ago. This I understand. Instead using Chrome's integrated cache viewer by typing about:cache in the address bar, I can search and find links that appear to be relevant, when I click on the link I just get a http header and a bunch of hexadecimal gobbledygook. I've tried to use the URL at the top of the cache and URLs in the http headers, but they take me to current versions of those pages and not the versions I saw during the checkout process. I tried this with a few of them but stopped because I noticed that it updated the date in the http header to the present moment and I don't want to take chances overwriting the cache files since I don't know what I'm doing.

(It's clear I can't achieve what I'm looking for by visiting current versions of these pages on the web…I should actually probably disable my network adapter while testing this out). The cache folder seems promising, but I don't know what to make of all that hexadecimal mess - if it contains what I'm looking for and if so, how to view it. Finally, the third thing I've come across is the Google Chrome cache folder on my local machine, at ~/Library/Caches/Google/Chrome/ then there are 'Default' and 'Media Cache' folders within. There are ~4,000 files in the former averaging ~100kb each, and 100 files in the latter averaging ~900kb each. The filenames all start "f_00xxxx" except for files titled data_0 through data_4 in each folder. I'm not sure how to observe the contents of these files and don't really want to start opening them up and potentially overwriting existing cached pages, as I notice there are already some holes in the arrangement of the files which I have never deleted manually. Hopefully this is an easy question to answer for someone who knows this stuff, admittedly web stuff is my weak point. As such, I've spent the past five hours searching around and trying to provide all the information I can. I'm probably asking for a miracle - like can those cached pages full of hexadecimal data be used to recreate the representation of the information that was on screen during the process? Or could screenshots of the previously viewed webpages be lurking in the /Caches folder? I have doubt because the content wasn't viewed at a permanent link, rather it seems like the on-screen information was served by Verizon's db, and probably securely so. I'm just not sure if Chrome saves the visual rendering of the page contents somewhere, even just temporarily. Alternatively I would be happy just to get the raw data that was on the page, even if not a visual representation…I just need to be able to demonstrate the phone line that was referenced on this page: https://preorder.verizonwireless.com/iconic/iconic/secured/screens/IconicFeatures.do . Can anyone point me in the right direction?

• Deeplinking using GWT History Token within a Facebook iFrame Canvas

  - by Stevko

  I would like to deep link directly to a GWT app page within a Facebook iFrame Canvas. The first part is simple using GWT's History token with URLs like: http://www.example.com/MyApp/#page1 which would open page1 within my app. Facebook Apps use an application url like: http://apps.facebook.com/myAppName which frames my Canvas Callback URL http://www.example.com/MyApp/ Is there a way to specify a canvas callback url (or bookmark url) which will take the user to a specific page rather than the index page? Why? you may ask. Besides all the benefits of deep links... I want the "Go To Application" url to take users to an index page w/ marketing material (the canvas callback url) I want the "Bookmark URL" to take (likely returning) users to a login page and bypass downloading the marketing content (and that huge SWF file).

• How to import classes into other classes within the same file in Python

  - by Chris

  I have the file below and it is part of a django project called projectmanager, this file is projectmanager/projects/models.py . Whenever I use the python interpreter to import a Project just to test the functionality i get a name error for line 8 that FileRepo() cannot be found. How Can I import these classes correctly? Ideally what I am looking for is each Project to contain multiple FileRepos which each contain and unknown number of files. Thanks for any assistance in advance. #imports from django.db import models from django.contrib import admin #Project is responsible for ensuring that each project contains all of the folders and file storage #mechanisms a project needs, as well as a unique CCL# class Project(models.Model): ccl = models.CharField(max_length=30) Techpacks = FileRepo() COAS = FileRepo() Shippingdocs = FileRepo() POchemspecs = FileRepo() Internalpos = FileRepo() Finalreports = FileRepo() Batchrecords = FileRepo() RFPS = FileRepo() Businessdev = FileRepo() QA = FileRepo() Updates = FileRepo() def __unicode__(self): return self.ccl #ProjectFile is the file object used by each FileRepo component class ProjectFile(models.Model): file = models.FileField(uploadto='ProjectFiles') def __unicode__(self): return self.file #FileRepo is the model for the "folders" to be used in a Project class FileRepo(models.Model): typeOf = models.CharField(max_length=30) files = models.ManyToManyField(ProjectFile) def __unicode__(self): return self.typeOf

• Open an Excel htm URL via iFrame in a separate browser

  - by Mark Robinson

  I have some URLs in an Excel file which I have saved as a .htm (webpage) file. I then view these in a browser via our wiki (MediaWiki). This is done using an iFrame embedded in the wiki page. So, just for clarity, the link is in a htm file viewed via an iFrame in a wiki page. When I click on that link, it opens inside the iFrame. What I want is for it to open in a new browser window. (This should be the user's default browser since some use Internet Explorer and some Firefox.) The final twist is that some users have Windows XP and some Solaris. Help greatly appreciated.

• Web publishing system with code highlighting

  - by Dragos Toader

  I'd like to publish some of the many programs I've written on the web. Is there a syntax highlighting Linux web publishing application (CMS/Blog/RoR app) that displays syntax for C++, Python, Bash scripts, SQL, VBA, awk, Erlang, java, makefiles, Ruby, Pascal and other languages? The more syntax settings configuration files, the better. The extensions I have in Textpad (for which I have syntax highlighting -- syn files) are .as, .asm, .asp, .awk, .bas, .bat, .c, .conf, .cpp, .cs, .ctl, .dfm, .dsc, .erl, .fnc, .h, .hpp, .inf, .ini, .jav, .java, .mak, .nsh, .nsi, .ora, .pas, .pkb, .pks, .pl, .prc, .py, .reg, .rsp, .sh, .sql, .syn, .tcl, .trg, .vw, .xml, .xsl, .xslfo

• Having py2exe include my data files (like include_package_data)

  - by cool-RR

  I have a Python app which includes non-Python data files in some of its subpackages. I've been using the include_package_data option in my setup.py to include all these files automatically when making distributions. It works well. Now I'm starting to use py2exe. I expected it to see that I have include_package_data=True and to include all the files. But it doesn't. It puts only my Python files in the library.zip, so my app doesn't work. How do I make py2exe include my data files?

• AJP proxy that maps internal servlet name to a different external name

  - by sakra

  Using apache2 I want to set up an AJP proxy for a Tomcat server that maps an internal servlet URL to a completely different URL externally. Currently I am using the following configurations: Apache2 configuration: <IfModule mod_proxy.c> ProxyPreserveHost on ProxyPass /external_name ajp://192.168.1.30:8009/servlet_name ProxyPassReverse /external_name ajp://192.168.1.30:8009/servlet_name </IfModule> Note that external_name and servlet_name are different. Tomcat 6 configuration: <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> This however does not work. Apache seems to forward http requests to Tomcat. However the URLs and redirects returned by Tomcat are still using the original servlet_name and Apache does not map them to external_name. Is this possible at all with AJP? If not can it be done using a plain http proxy instead?

• Is there built-in method to tell if specific URL belongs to this SPWeb or other SPWeb?

  - by Janis Veinbergs

  Hello. I have a list of urls (content type usage url's). Now, content types are deployed across web's. I need to loop those content types and do some actions in each list, but opening new SPWeb instance every loop is too resource intensive. Is there built-in method to tell me if this URL belongs to certain SPWeb object? Example: SPWeb's may be http://server/web1 http://server/web2 http://server/web2/subweb1 http://server/web2/subweb2 With content type usage links like: /web2/Pages /web2/Lists/Tasks /web2/Lists/Documents /web2/subweb1/Lists/Tasks ... As you can see, for first 3 usages i don't need to open up new SPWeb

• Using IIRF to redirect to a PDF

  - by Michael Itzoe

  I'm using IIRF to redirect certain URLs to specific PDF files. For instance, for the URL /newsletter/2010/02 I'd like it to redirect to /pdf/newsletters/Feb2010.pdf. I'm not too hot at regular expressions, but I created the following rule: RedirectRule ^/newsletter/2010/01 /pdf/newsletters/Newsletter012010.pdf [I,R=301] and it does redirect, but the address bar doesn't change, and when trying to save the file it wants to save as 01 instead of Feb2010.pdf. I don't presume my users will be savvy enough to enter a PDF extension before saving, and they shouldn't have to. Is there anything I can do about this?

• Django ImageField validation & PIL

  - by Zayatzz

  Hello On sunday, I had problems with python modules, when I installed stackless python. Now I have compiled and installed : setuptools & python-mysqldb and i got my django project up and running again. (i also reinstalled django-1.1), Then I compiled and installed, jpeg, freetype2 and PIL. I also started using mod_wsgi instead of mod_python. But when uploading imagefield in form I get validationerror: Upload a valid image. The file you uploaded was either not an image or a corrupted image. Searchmonkey shows that it comes from field.py imagefield validation. before raising this error it imports Image from PIL, opens file and verfies it. I tried importing PIL from python prompt manually - it worked just fine. Same with Image.open and Image.verify. So what could be causing this problem? Alan

• jquery-Ajax call on tornado handlers waits for pervious ajax call to return

  - by harshh

  Hey All. I recently started testing TornadoWeb for a home-project, which uses jquery getJSON function to call my tornado handlers. And found something strange, which i seek an explanation for. I fire an ajax request for Handler1 on tornado, and in some cases request for Handler2 is initiated before Handler1 returns. It appears from development-server logs, and firebug console-debugging, that Handler2 request waits for Handler1 request to finish, and then return. So basically, XHR call is waiting for earlier XHRs. They are supposed to be asynchronous/non-blocking right?? Or am i missing something. You can check the test-case environment called testtornado at http://github.com/harshh/Harsh-Projects/ with main.py as server triggering file. I would appreciate help from anyone who can throw some light on this.

• exe files and Python

  - by Sorush Rabiee

  i have some questions about python: 1- How to build .exe files from .py files? 2- How to run a program with arguments and receive the result by python code? 3- How to load .NET library in python code (or write python in VS.NET IDE [!?])? 4- is built-in integer of python 3.1 something like a string? it calculates 200! in less than one second and calculates 2^1 to 2^7036 (by a simple recursive algorithm & writing them to a text file) with a 1.75GHz cpu in 4 minuets, so if it is a string, how it can be so fast like this? is there a great difference between memory type and logical calculation of python with c++? 5- what is the best python practice? how can i be an expert?

• How Does DotNetNuke Stack Up For SEO? E-Commerce?

  - by user326502

  I've heard that DotNetNuke takes a bit of a hit for Search Engine Optimization. I'm not criticizing the platform, by the way; I love DNN. This is just what I've heard. As I understand it, the impact is from repetitive content, table-based layouts, and lots of extra markup. I've got a friend who would like to start an e-commerce site using DNN and some modules from Snowcovered. I was just wondering whether DNN would be a good platform to choose. The idea is attractive because of the ease with which a DNN commerce system can be deployed. Search-engine friendly URLs aren't the problem - the modules do that, it's whether DNN as a whole would be a good platform for this. Thanks very much for any help or advice.
