  • advice on working on remote asp.net applications

    - by Jonesy
    Hi folks, I'm a (relatively new) developer using asp.net with VB.NET. Currently all my applications are developed on my PC and then are built and moved onto the web server. I'm going to be working remotely for 3 months in which time I'll be connecting to the company network via VPN. What is the best way to access my projects? I need to have the projects stored on the company network so that others can access them too. So simply copying the projects to my laptop, working on them, then copying them back won't suffice. I tried to just open the projects off of the network share but am getting application trust problems. I'm just wondering what other developers do in this situation? Jonesy

  • Find the minimum gap between two numbers in an AVL tree

    - by user1656647
    I have a data structures homework, that in addition to the regular AVL tree functions, I have to add a function that returns the minimum gap between any two numbers in the AVL tree (the nodes in the AVL actually represent numbers.) Lets say we have the numbers (as nodes) 1 5 12 20 23 21 in the AVL tree, the function should return the minimum gap between any two numbers. In this situation it should return "1" which is |20-21| or |21-20|. It should be done in O(1). Tried to think alot about it, and I know there is a trick but just couldn't find it, I have spent hours on this. There was another task which is to find the maximum gap, which is easy, it is the difference between the minimal and maximal number.

  • Language of variable names? (native foreign language speakers)

    - by Jj
    We are a spanish speaking development team, we code in django and we all are pretty fluent in english, as all documentation, sample code, APIs, etc come in english. On our last project we chose to name all the variables, class names, modules, files and such in english, even though the whole application was in spanish, we kept a strings file where all our spanish was stored. We did this because it seemed more natural to read the whole code in one language, since keywords, constructs and dependencies have names in english. On new projects we are starting, we are having second thoughts about other teams mantaining our code or just having 3rd parties having to deal with templates or context in spanish. Do you know of any best practice on this matter?

  • Paypal adaptive payment API call with C# .NET? Preferably with WebServices

    - by Phil
    Okay I might be entirely off track now but here goes: Our "webshop" offers two functions, buying a specific product and selling it back to us. Back-end handles if the user can sell or not. I've decided to use Paypal's adaptive payments for this one as it seems the way to go doing these kinds of transactions. I've never implemented any kind of shop so I'm totally green with this one. I only recently learned ASP.NET and have mainly developed games before moving to this kind of development. HTTP is still some level of magic to me hehe.. I might be confused but I think paypal offers a webservice with their adaptive payment API. My humble request: A nice soul who wants to share an example of implementing an adaptive payment API call with C# .NET. If they don't offer it as a webservice I'll probably find it as a custom .dll or something. Any tips and examples are highly appreciated! Thanks for reading

  • Thoughts on security model to store credit card details

    - by Faisal Abid
    Here is the model we are using to store the CC details how secure does this look? All our information is encrypted using public key encryption and the keypair is user dependent (its generated on the server and the private key is symmetric encrypted using the users password which is also Hashed on the database) So basically on first run the user sends in his password via a SSL connection and the password is used with the addition of salt to generate an MD5 hash, also the password is used to encrypt the private key and the private key is stored on the server. When the user wants to make a payment, he sends his password. The password decrypts the private key, and the private key decrypts the CC details and the CC details are charged.

  • Anyone using NoSQL databases for medical record storage?

    - by Brian Bay
    Electronic Medical records are composed of different types of data. Visit information ( date/location/insurance info) seems to lend itself to a RDMS. Other types of medical infomation, such as lab reports, x-rays, photos, and electronic signatures, are document based and would seem to be a good candidate for a 'document-oriented' database, such as MongoDB. Traditionally, binary data would be stored as a BLOB in a RDBMS. A hybrid approach using a traditional RDBMS along with a 'document-oriented' database would seem like good alternative to this. Other alternative would be something like DB2 purexml. The ultimate answer could be that 'it depends', but I really just wanted to get some general feedback/ideas on this. Is anyone using the NoSql approach for medical records?

  • Is there an extensible SQL like query language that is safe for exposing via a public API?

    - by Lokkju
    I want to expose some spatial (and a few non-spatial) datasets via a public API. The backend store will either be PostgreSQL/PostGIS, sqlite/spatialite, or CouchDB/GeoCouch. My goal is to find a some, preferably standard, way to allow people to make complex spatial queries against the data. I would like it to be a simple GET based request. The idea is to allow safe SQL type queries, without allowing unsafe ones. I would rather modify something that is off the shelf than doing the entire thing myself. I specifically want to support requesting specific fields from a table; joining results; and spatial functions that are already implemented by the underlying datastore. Ideas anyone?

  • How does MTOM work + sample code

    - by zengr
    I am trying to make a very simple web-service which does the following: The client hits the web service requesting a file. The web service's service class queries a hashtable which has the key (search query) and the value as the base64encoded value of a file (say a pdf) Now,I need to use MTOM to return the base64encoded value stored in the hashtable to the client. It's upto the client to decode it and convert it to pdf. So, here are my questions: I understand we encode files to base64 for transmission via web service, but where and how does MTOM come into the picture there? Can some one provide me a simple method which uses MTOM and sends the data back. Do we need to specify something in the WSDL too? or a simple String return type would suffice? Why/Why not? Thanks I have seen this code. It uses a lot of annotations, I just need a simple java code using MTOM. New to J2EE HERE :)

  • Does this schema sound better suited for a document-oriented data store or relational?

    - by Blaine LaFreniere
    Disclaimer: let me know if this question is better suited for serverfault.com I want to store information on music, specifically: genres artists albums songs This information will be used in a web application, and I want people to be able to see all of the songs associated to an album, and albums associated to an artist, and artists associated to a genre. I'm currently using MySQL, but before I make a decision to switch I want to know: How easy is scaling horizontally? Is it easier to manage than an SQL based solution? Would the above data I want to store be too hard to do schema-free? When I think association, I immediately think RDBMSs; can data be stored in something like CouchDB but still have some kind of association as stated above?

  • Best practices on what data to collect in an in-app web analytics

    - by Anton Gogolev
    Hi! In our SaaSy webapp we need to collect Google Analytics-like data (like, what pages were visited, how many 404s where there, etc.). I wonder if there are any best practices on what pieces of information should be collected (like, IP, User Agent, etc.) and how should these logs be stored. Requirements on what statistics we're going to display are not yet fixed, but I want to have a starting point. Can you help me out with this? Thanks.

  • How to deal with OpenMP thread pool contention

    - by dpe82
    I'm working on an application that uses both coarse and fine grained multi-threading. That is, we manage scheduling of large work units on a pool of threads manually, and then within those work units certain functions utilize OpenMP for finer grain multithreading. We have realized gains by selectively using OpenMP in our costliest loops, but are concerned about creating contention for the OpenMP worker pool as we add OpenMP blocks to cheaper loops. Is there a way to signal to OpenMP that a block of code should use the pool if it is available, and if not it should process the loop serially?

  • jQuery to get innerHTML not working on a HTMLFontElement object...

    - by Matt
    I have jQuery to select all font elements that are children of the element with id="right" within the html stored in the var html... when I do an alert to see how many elements it gets: alert($("#right > font", html).length); it gives me an alert of: 5 but when I try any of the following, I don't get any alerts... alert($("#right > font", html)[0].html()); alert($("#right > font", html)[0].text()); alert($("#right > font", html)[0].val()); Any Ideas? Thanks, Matt

  • store everything only once, smarter

    - by hsmit
    In the digital world a lot is stored multiple times. As a thought experiment or creative challenge I want you to think about making this more efficient and maybe reuse more. Think of the following cases: an mp3 track is downloaded multiple times, copied over various devices on website a login form is often rebuild many times, why not reuse more code? words themselves are used many times questions and answers are accidentally saved at many places in parallel images or photos often describe the same data (Eiffel tower, Golden gate, Taj Mahal) etc etc Are you aware of solutions? Or are you thinking about similar topics? Ideas? Blueprints? I'd love to hear from you!

  • oracle pl sql dump result into file

    - by CC
    Hi. I'm working on a pl sql stored procedure. What I need is to do a select, use a cursor and for every record build a string using values. At the end I need to write this into a file. I try to use dbms_output.put_line("toto") but the buffer size is to small because I have about 14 millions lines. I call my procedure from a unix ksh. I'm thinking at something like using "spool on" (on the ksh side) to dump the result of my procedure, but I don' know how to do it (if this is possible) Anyone has any idea? Thank alot. C.C.

  • What "already invented" algorithm did you invent?

    - by Guy
    In my question Insert Update stored proc on SQL Server I explained an efficient way of doing an insert/update - perhaps THE most efficient. It's nothing amazing but it's a small algorithm that I came up with in a mini-Eureka moment. Although I had "invented" it by myself and secretly hoped that I was the first to do so I knew that it had probably been around for years but after posting on a couple of lists and not getting confirmation I had never found anything definitive written up about it. So my questions: What software algorithm did you come up with that you thought that you'd invented? Or better yet, did you invent one?

  • Detecting if the user selected "All Users" or "Just Me" in a Custom Action

    - by Ben
    Hi, I'm trying to detect if the user has selected the "All Users" or the "Just Me" radio during the install of my program. I have a custom action setup that overrides several methods (OnCommit, OnBeforeInstall, etc.). Right now I'm trying to find out this information during OnCommit. I've read that the property I want to get at is the ALLUSERS property, but I haven't had any luck finding where it would be stored in instance/local data. Does anyone know of a way to get at it? -Ben

  • Handy F# snippets

    - by Benjol
    There are already two questions about F#/functional snippets. However what I'm looking for here are useful snippets, little 'helper' functions that are reusable. Or obscure but nifty patterns that you can never quite remember. Something like: open System.IO let rec visitor dir filter= seq { yield! Directory.GetFiles(dir, filter) for subdir in Directory.GetDirectories(dir) do yield! visitor subdir filter} I'd like to make this a kind of handy reference page. As such there will be no right answer, but hopefully lots of good ones.

  • Which hosting will let me execute my own EXE with PHP?

    - by guitar-
    I have a task that PHP (or any server-side scripting language) isn't practical for. It involves a lot of file I/O, processing, etc. and it will execute a lot faster using the program I made in C instead of PHP. Do any hosts allow you to upload your own EXE files and run them on the server using PHP's exec, shell_exec, etc. functions? Do you need a dedicated server to do this? Also, I don't know if Facebook's PHP HipHop is out yet, but I really don't want to use that.

  • will paginate, nested routes, ruby, rails

    - by Sam
    I'm trying to get will paginate to link to my nested route instead of the regular posts variable. I know I'm supposed to pass some params to paginate but I don't know how to pass them. Basically there is an array stored in @posts and the other param paginate has access to is category_id. The nested route is /category/1/posts but hitting next and previous on will paginate returns a url like this posts?page=1&category_id=7. <%= will_paginate @most_recent_posts "What do I do here?" %> This is the result of Yannis's answer: In your controller you can do: @posts = @category.posts.paginate And in your view: <%= will_paginate(@post) %> Doing this comes up with the following URL posts?page=2&post_category_id=athlete_management routes.rb #there are more routes but these are the relevant ones map.resources :posts map.resources :post_categories, :has_many => :posts solution map.resources :post_categories do |post_category| post_category.resources :posts end map.resources :posts Had to declare the resource after the block Thanks stephen!

  • Localization — how to check that Filename1 and Filename2 are the same

    - by modosansreves
    I want to know that Filename1, provided by the user is the same as stored in DB (Filename2). I was about to use string.Equals(Filename1, Filename2, StringComparison.CurrentCultureIgnoreCase) but then I doubted whether I should use StringComparison.InvariantCultureIgnoreCase. Obviously, I need to do this the same way OS does, or use appropriate API. In some cultures, AFAIK, characters (e.g. vocals) may change if the next one is Capitalized. As I primarily target English-speaking market, I'd like my software to work well throughout the world.

  • PHP/Cronjob: What is my Cronjobs problem?

    - by Marius
    Hello there, I have no idea whats going on. But I have a script that looks like this. Cron job refuses to run it: include_once 'class_lib/mime_mail/mimeDecode.php'; include_once 'class_lib/Mail/IMAPv2.php'; include_once 'inc-functions.php'; include_once "$_SERVER[DOCUMENT_ROOT]/class_lib/DbFuctioneer.php"; $dbFuctioneer = new DbFuctioneer(); Everything works well when I remove: $dbFuctioneer = new DbFuctioneer(); Even when DbFuctioneer() looks like this: <?php class DbFuctioneer { function dbCountMatches( $count) { return $count; } } Does Cron have a problem with Classes in his Jobs? Thank you for your time. Kind regards, Marius

  • cygwin slow file open

    - by Erdem
    My application uses fopen to open a lot of files. While in linux opening and reading thousand of files doesn't even take a second; in cygwin it takes more than 5 seconds. I think it is because path conversion functions in cygwin dlls. 'open' function is a bit faster. If I use -mno-cygwin it becomes very fast but I can't use it. Is there an easy way to make cygwin dlls just open files; without any linux-windows conversion?
