  • Split comma separated string to count duplicates

    - by josepv
    I have the following data in my database (comma separated strings): "word, test, hello" "test, lorem, word" "test" ... etc How can I transform this data into a Dictionary whereby each string is separated into each distinct word together with the number of times that it occurs, i.e. {"test", 3}, {"word", 2}, {"hello", 1}, {"lorem", 1} I will have approximately 3000 rows of data in case this makes a difference to any solution offered. Also I am using .NET 3.5 (and would be interested to see any solution using linq)

  • Django users and authentication from external source

    - by Boldewyn
    I have a Django app that gets it's data completely from an external source (queried via HTTP). That is, I don't have the option for a local database. Session data is stored in the cache (on my development server I use a SQLite database, so that is no error source). I'm using bleeding edge Django 1.1svn. Enter the problem: I want to use Django's own authentication system for the users. It seems quite simple to write my own Authentication Backend, but always just under the condition that you have a local database where to save the users. Without database my main problem is persistence. I tried it with the following (assume that datasource.get() is a function that returns some kind of dict): class ModelBackend (object): """Login backend.""" def authenticate (self, username=None, password=None): """Check, if a given user/password combination is valid""" data = datasource.get ('login', username, password) if data and data['ok']: return MyUser (username=username) else: raise TypeError return None def get_user (self, username): """get data about a specific user""" try: data = datasource.get ('userdata', username) if data and data['ok']: return data.user except: pass return None class MyUser (User): """Django user who isn't saved in DB""" def save (self): return None But the intentionally missing save() method on MyUser seems to break the session storage of a login. How should MyUser look like without a local database?

  • jQuery plugin, return value from function

    - by Marius
    Hello there, Markup: <input type="text" name="email" /> Code: $(':text').focusout(function(){ $(this).validate(function(){ $(this).attr('name'); }); }); Plugin: (function($){ $.fn.validate = function(type) { return this.each(function(type) { if (type == 'email') { matches = this.val().match('/.+@.+\..{2,7}/'); (matches != null) ? alert('valid') : alert('invalid'); } /*else if (type == 'name') { } else if (type == 'age') { } else if (type == 'text') { }*/ else { alert('total failure'); } }); }; })(jQuery); The problem is that when I execute the code above, it runs the plugin as if type was a string: "function(){ $(this).attr('name'); });" instead of executing it as a function. How do I solve this? Thank you for your time. Kind regards, Marius

  • What is the Benefit of Onsite SEO?

    Search Engine Optimisation or SEO for short can be extremely expensive if you are to use the local SEO company. It is one of those areas, which can involve lots of expense for potentially little or no visible benefit. Therefore if you are considering using an SEO service you need to have a good understanding of what SEO is, what you are looking to achieve by having someone conducting SEO work, and how this achievement is measured.

  • How many times can you randomly generate a GUID before you risk duplicates? (.NET)

    - by SLC
    Mathematically I suppose it's possible that even two random GUIDs generated using the built in method in the .NET framework are identical, but roughly how likely are they to clash if you generate hundreds or thousands? If you generated one for every copy of Windows in the world, would they clash? The reason I ask is because I have a program that creates a lot of objects, and destroys some too, and I am wondering about the likelihood of any of those objects (including the destroyed ones) having identical GUIDs.

  • Open source alternative for "Intellisense"

    - by Elazar Leibovich
    Microsoft has recently announced "Intellisense", a killer feature for VS2010 IMHO. Basically it records all the instructions the program ran, and allows you to easily look through the execution log. Is there a similar feature for open source tools? Specifically such a feature for Java with Eclipse integration would be a nice thing to have.

  • naive bayesian spam filter question

    - by Microkernel
    Hi guys, I am planning to implement spam filter using Naive Bayesian classification model. Online I see a lot of info on Naive Bayesian classification, but the problem is its a lot of mathematical stuff, than clearly stating how its done. And the problem is I am more of a programmer than a mathematician (yes I had learnt Probability and Bayesian theorem back in school, but out of touch for a long long time, and I don't have luxury of learning it now (Have nearly 3 weeks to come-up with a working prototype)). So if someone can explain or point me to location where its explained for programmers than a mathematician, it would be a great help. PS: By the way I have to implement it in C, if you want to know. :( Regards, Microkernel

  • Error when feeding a mysql db with a python-parsed data

    - by Barnabe
    I use this bit of code to feed some data i have parsed from a web page to a mysql database c=db.cursor() c.executemany( """INSERT INTO data (SID, Time, Value1, Level1, Value2, Level2, Value3, Level3, Value4, Level4, Value5, Level5, ObsDate) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)""", clean_data ) The parsed data looks like this (there are several hundred such lines) clean_data = [(161,00:00:00,8.19,1,4.46,4,7.87,4,6.54,null,4.45,6,2010-04-12),(162,00:00:00,7.55,1,9.52,1,1.90,1,4.76,null,0.14,1,2010-04-12),(164,00:00:00,8.01,1,8.09,1,0,null,8.49,null,0.20,2,2010-04-12),(166,00:00:00,8.30,1,4.77,4,10.99,5,9.11,null,0.36,2,2010-04-12)] if i hard code the data as above mySQL accepts my request (except for some quibbles about formatting) but if the variable clean_data is instead defined as the result of the parsing code, like this: cleaner = [(""" $!!'""", ')]'),(' $!!', ') etc etc] def processThis(str,lst): for find, replace in lst: str = str.replace(find, replace) return str clean_data = processThis(data,cleaner) then i get the dreaded "TypeError: not enough arguments for format string" After playing with formatting options for a few hours (I am very new to this) I am confused... what is the difference between the hard coded data and the result of the processThis function as fas as mySQL is concerned? Any idea greatly appreciated...

  • Optimally reducing maximum flow

    - by ArIck
    Given a parameter k, I'm trying to delete k edges from a directed graph such that the maximum flow is reduced by as much as possible. The graph has a source s and a sink t, and the capacity of each edge is one. The graph may or may not contain cycles. My proposed solution would be to first perform a topological sorting on the graph, using an algorithm that "forgives" cycles -- perhaps by ignoring edges that lead us back to the source. Then (assuming k = 1): i = 0 for each vertex u order by topological(u) for each edge (u, v) order by topological(v) descending if topological(v) > topological(u) then delete (u, v) if ++i = k then return else // edge doesn't contribute to max flow, ignore Would this work, or am I totally off-track here?

  • How te execute with /bin/false shell

    - by Amar
    Hello I am trying to setup per-user fastcgi scripts that will run each on different port and with different user. Here is example of my script: #!/bin/bash BIND=127.0.0.1:9001 USER=user PHP_FCGI_CHILDREN=2 PHP_FCGI_MAX_REQUESTS=10000 etc... However, if I add user with /bin/false (which I want, since this is about to be something like shared hosting and I dont want users to have shell access), the script is run'd under 1001, 1002 'user' which, as I googled, might be security hole. My question is: Is it possible to allow user(s) execute shell scripts but disable them to log in via SSH ? Thank you

  • Best Youtube embed player sizes?

    - by Xeoncross
    I use tumblr to share videos and, unfortunately, when re-posting a video to your tumblelog it uses the embed code at 400x336px. This is neither widescreen nor very large. So I'm trying to set the player to better size and I'm finding that the youtube player really comes in many sizes. For example, when copying the embed code for and HD video I get the sizes 560x340, 640x385, and 853x505. Then when I look at the embed code for a SD video I get the sizes 425x344, 480x385, and 640x505. I was having the best luck with setting the player to 640 x 505 as it was large enough for HD and perfect for SD. print str_replace( array('400', '336'), array('640', '505'), $video_player_html); Has anyone dealt with trying to find a good standard embed size for a site? One thing that would make this a lot easier is to know whether the video was HD or not - however, that info is not provided in the embed code. I guess I am actually more interested in knowing the right ratio (or specific size) to use that works the best for youtube's mixed content.
