  • natural language processing internships

    - by user552127
    Hi All, Pls someone guide me in finding paid Grad internships in Natural Language Processing over the summer. I am really interested in NLP/ML and have taken up the excellent course offered at my school in Fall. I would be glad to work for passionate startups that do actual NLP tasks such as semantic extraction (and not just information retrieval) etc. I have worked with Java and teaching myself Python in all NLP tasks. Thanks, Sanjay

  • How to choose programming language for projects?

    - by bdhar
    This is a question I constantly encounter when I attend any technical forums / discussions / interviews. There is a similar article but it focuses on business merits as well. What I am looking for is a guide (not a checklist like this one which is abstract and not so accurate) which helps an architect to choose the programming language to implement a requirement. Is there a book or article available for the same purpose?

  • Handling national language prefix for checkconstraints

    - by Chris Chilvers
    I'm trying to create a check constraint such as CHECK Type IN (N'Create', N'Remove') for an enumeration's value. Sqlite complains about this syntax and only accepts CHECK Type IN ('Create', 'Remove'). The main database will be Sql Server 2005, but I use sqlite's in memory database for unit tests. Is there any way to get sqlite to recognise the national language (N) prefix? Alternatively, is there an easy way when using FluentNHibernate to adapt an nvarchar constant to match the database's dialect?

  • What Language is This?

    - by bobber205
    Going through some example code sent to me and honestly, I have no idea what language this is def uniqify(arr): b = {} for i in arr: b[i] = 1 return b.keys() Is it Python? I am also curious what keys() does. It's obvious it returns an array but what does it do the array that calls the function? :P

  • What is your longest-held programming assumption that turned out to be incorrect?

    - by Demi
    I am doing some research into common errors and poor assumptions made by junior (and perhaps senior) software engineers. What was your longest-held poor assumption that was eventually corrected? For example: I at one point failed to understand that the size of an integer was not a standard (depends on the language and target). A bit embarrassing to state, but there it is. Be frank: what hard-held belief did you have, and roughly how long did you maintain the assumption? It can be about an algorithm, a language, a programming concept, testing, anything under the computer science domain.

  • Map Reduce Frameworks/Infrastructure

    - by Johannes Rudolph
    Map Reduce is a pattern that seems to get a lot of traction lately and I start to see it manifest in one of my projects that is focused on an event processing pipeline (iPhone Accelerometer and GPS data). I needed to built a lot of infrastructure for this project, in fact it overweighs the logic code interacting with it by 2x. Some of the components I built where EventProcessors (with in- and output plus buffering, timing etc.), multiplexers and aggregators. This leads me to my question what the "common" required infrastrucutre for map reduce is. Since I am working with .Net a lot I can see map reduce infrastructure built into the Framework and language constructs. Functional languages support this paradigm per se. It seems every language can be used with map reduce, some have better support than others, others again are built around that concept (e.g. Go). And there are Frameworks like Apache Hadoop to support map reduce.

  • How to store a public key in a machine-level RSA key container

    - by Andrew Kimball
    I'm having a problem using a machine level RSA key container when storing only the public key of a public/private key pair. The following code creates a public/private pair and extracts the public key from that pair. The pair and the public key are stored in separate key containers. The keys are then obtained from those key containers at which point they should be the same as the keys going into the containers. The code works when CspProviderFlags.UseDefaultKeyContainer is specified for CspParameters.Flags (i.e. the key read back out from the PublicKey container is the same), but when CspProviderFlags.UseMachineKeyStore is specified for CspParameters.Flags the key read back from PublicKey is different. Why is the behaviour different, and what do I need to do differently to retrieve the public key from a machine-level RSA key container? var publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true, }; var publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true }; //Export the key. publicRsa.ImportParameters(publicPrivateRsa.ExportParameters(false)); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); //Dispose those two CSPs. using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); } publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); }

  • Implementing dynamic scope when using CPS as intermediate language

    - by asandroq
    I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

  • Concepts a web application developer should know?

    - by iama
    I think it is imperative for web application developers to know the answers surrounding the following general questions on web development irrespective of the programming language/framework used. What authentication mechanisms HTTP offer & what are their pros and cons? Why should one go for FORMS authentication? How to secure authentication or for that matter any transactions via HTTP? How to maintain state in HTTP? What are the downsides to maintaining state via cookie & what happens when browsers disable them? Security issues like cross site scripting, session hijacking etc. What other questions a web developer should have answers for similar to the ones above that are programming language/web framework agnostic?

  • ASP.NET spellchecker - Multi language

    - by Srikanth
    I am looking at various options to implement a spellchecker in our ASP.NET 3.5 application. This applicaition is to be used worldwide so a wide language support is important. Can you guys suggest the best possible controls for this purpose? Currently, we are evaluating Obout and Telerik suites. Are there better alternatives, given that spellcheck is our primary goal? thanks

  • Tag/Keyword based recommendation

    - by Hellnar
    Hello I am wondering what algorithm would be clever to use for a tag driven e-commerce enviroment: Each item has several tags. IE: Item name: "Metallica - Black Album CD", Tags: "metallica", "black-album", "rock", "music" Each user has several tags and friends(other users) bound to them. IE: Username: "testguy", Interests: "python", "rock", "metal", "computer-science" Friends: "testguy2", "testguy3" I need to generate recommendations to such users by checking their interest tags and generating recommendations in a sophisticated way. Ideas: A Hybrid recommendation algorithm can be used as each user has friends.(mixture of collaborative + context based recommendations). Maybe using user tags, similar users (peers) can be found to generate recommendations. Maybe directly matching tags between users and items via tags. Any suggestion is welcome. Any python based library is also welcome as I will be doing this experimental engine on python language.

  • What programming language is the most English-like?

    - by asmeurer
    I'm mainly a Python programmer, and it is often described as being "executable pseudo-code". I have used a little bit of AppleScript, which seems to be the most English-like programming language I have ever seen, because almost operators can be words, and it lets you use "the" anywhere (for example, this stupid example I just came up with: firstnumber = 1 secondnumber = 2 if the firstnumber is equal to the secondnumber then set the sum to 5 end if is a valid AppleScript program. Are there any programming languages that are even more English-like than these?

  • Statement hierarchy in programming languages

    - by sudo
    I quickly wrote an interpreter for some sort of experimental programing language i came up with, in PHP (yes, in PHP). The language itself doesn't have anything really special, I just wanted to give it a try. I got the basic things working (Hello World, input to output, string manipulation, arithmetics) but I'm getting stuck with the management of blocks and grouped statements. What I mean is: PHP and most other languages let you do this: ((2+2)*(8+2)+2), of course not only with mathematical computations. My program structure currently consists of a multidimensional array built like this: ID => Type (Identifier, String, Int, Newline, EOF, Comma, ...) Contents (If identifier, int or string) How could I allow statements to be executed in a defined order like in the PHP example above?

  • Retrieving the URL in Django template language

    - by Vernon
    In a Django template, how could I refer to the URL. I want to use it in static pages, to avoid having live links to the current page. Is there a way to do this with the Django template language or do I have to use JavaScript to do it? I would like to do something like {% if current_url == "/about/" %} About {% else %} <a href='/about/'>About</a> {% endif %} I'm using it for a simple blog, so there are no views written for those pages.

  • Are frameworks using byte-code generation creating leaky abstractions?

    - by Gabriel Šcerbák
    My point is, if you don't understand the abstraction of a framework, you can still decompile it and understand it, because you know the language e.g. Java. However, when byte-code generation happens, you have to understand even a lower level - JVM level byte-codes. I am really affraid of using any of such frameworks, which are many. Most of the time I think the reason for byte-code generation is simply lack of language features such as metaprogramming. Do you agree? What is your opinion and argument? How do you take over the problem with leaky abstractions in those frameworks?

  • Which programming language to use for serious project?

    - by alex
    Hi! Which programming language to use for serious web project (price catalogue)? After some time of studying web PHP frameworks i got that: Codeigniter: good, but when i read about authorization (that 20% users can login correctly without party solutions), i am disappointed. Zend Framework: more serious, but raises questions about speed and i found only few examples. PHP: long time to understand PHP frameworks functionality

  • Languages/Technologies advice

    - by BL
    Hi all, a bit of advice required here :). I recently graduated(Computer Science), and need to decide a path to take programming/technology wise. I have knowledge of Java, C, SQL most of it is university level stuff. I work daily with PHP/SQL building web apps. Which language / technology would you advise me to learn. I am very interested in Database management, GIS etc. Web dev is also very interesting to me. It is all a bit confusing since i would like to learn something that will have a value at least in the near future. I would like to have some ideas on which language/technology is god choice in order to be marketable.
