  • In what specific areas has F# proven more applicable than C#?

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#. EDIT: Altered title with the intent of reducing perceived ambiguity.

  • PHP Include Paths

    - by Keiron Lowe
    Hi, I'm new to PHP and I'm having a problem when trying to link my CSS files using include. Basically I need my files to link back to a certain directory no matter how far down the file is. I have tried using <?php include $_SERVER['DOCUMENT_ROOT'] . '/sysprogs/required/header.html'; ?> But header.html contains the links to my css files so the directory it ends up looking for the css files in is http://localhost/SysProgs/software/CSS/style.css instead of where I want it to go to which is http://localhost/SysProgs/required/CSS/style.css I hope that made sense and I hope you can help me

  • Algorithm to emulate mouse movement as a human does?

    - by Eye of Hell
    Hello I need to test a software that treats some mouse movements as "gestures". For such a task I need to emulate mouse movement from point A to point B, not in straight line, but as a real mouse moves - with curves, a bit of jaggedyness etc. Is there any available solution (algorithm/code itself, not a library/exe) that I can use? Of course I can write some simple sinusoidal math by myself, but this would be a very crude emulation of a human hand leading a mouse. Perhaps such a task has been solved already numerous times, and I can just borrow an existing code? :)

  • Which set(s) of video lectures for computer science?

    - by SebKom
    As most of you know a couple of top universities (MIT, Stanford, etc) around the world are now publishing videos of their lectures online. I am advancing to the third and final year of my computer science degree this September and I was thinking about spending some time during the summer to watch a couple of lectures, in order to improve my understanding of algorithms, complexity, programming, software engineering, etc. Now I don't have infinite time to spend so I can't watch all of the lectures from all of the universities so I was wondering if you could suggest me which sets to watch from each one (something like "Algorithms from MIT", "Programming from Yale", etc).

  • HelpSpot to Fogbugz to HelpSpot integration

    - by James Ludlow
    Does anyone have a nice example of integration between HelpSpot and Fogbugz? We're using HelpSpot as our customer facing software and ticket management, and then if a developer needs to work on a ticket the data will be pushed to Fogbugz. Obviously we can use the Fogbugz push API that Userscape provides, but this only allows you to specify the title of the incident in Fogbugz. Ideally I want to share title, assigned to, category and status in a two-way integration. Do most people just use emails between the two programs, or has anyone come across a nice third party app? Thanks in advance!

  • Where can I find soft-multiply and divide algorithms?

    - by srking
    I'm working on a micro-controller without hardware multiply and divide. I need to cook up software algorithms for these basic operations that are a nice balance of compact size and efficiency. My C compiler port will employ these algos, not the the C developers themselves. My google-fu is so far turning up mostly noise on this topic. Can anyone point me to something informative? I can use add/sub and shift instructions. Table lookup based algos might also work for me, but I'm a bit worried about cramming so much into the compiler's back-end...um, so to speak. Thanks!

  • GUI design techniques to enhance user experience

    - by aku
    What techniques do you know\use to create user-friendly GUI ? I can name following techniques that I find especially useful: Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area) Absence of "Save" button MS OneNote as an example. IM clients can save conversation history automatically Integrated search Search not only through help files but rather make UI elements searchable. Vista made a good step toward such GUI. Scout addin Microsoft Office was a really great idea. Context oriented UI (Ribbon bar in MS Office 2007) Do you implement something like listed techniques in your software? Edit: As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.

  • Discovering maximum packet size

    - by ereOn
    I'm working on a network-related project and I am using DTLS (TLS/UDP) to secure communications. Reading the specifications for DTLS, I've noted that DTLS requires the DF flag (Don't Fragment) to be set. On my local network if I try to send a message bigger than 1500 bytes, nothing is sent. That makes perfect sense. On Windows the sendto() reports a success but nothing is sent. I obviously cannot unset the DF flag manually since it is mandatory for DTLS and i'm not sure whether the 1500 bytes limit (MTU ?) could change in some situations. I guess it can. So, my question is : "Is there a way to discover this limit ?" If not, what would be the lowest possible value ? My software runs under UNIX (Linux/MAC OSX) and Windows OSes so different solutions for each OS are welcome ;) Many thanks.

  • Check result of AX_PYTHON_MODULE in configure.ac

    - by tmatth
    In using the m4_ax_python_module.m4 macro in configure.ac (AX_PYTHON_MODULE), one can know at configure time if a given module is installed. It takes two arguments, the module name, and second argument which if not empty, will lead to an exit, useful when the module is a must-have. In the case where you don't want a fatal exit, how do you test in configure.ac which modules were found or not? They output "yes" or "no" when configure is run, but that's all I've found so far. Basically If I have these lines in configure.ac: AX_PYTHON_MODULE(json,[]) AX_PYTHON_MODULE(simplejson,[]) How do I test which of the two modules were found? See http://www.gnu.org/software/autoconf-archive/ax_python_module.html#ax_python_module for documentation about this macro.

  • I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Release m

    - by BHOdevelopper
    Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

  • Method of documentation for SQL Stored Procedures

    - by Chapso
    I work in a location where a single person is responsible for creating and maintaining all stored procedures for SQL servers, and is the conduit between software developers and the database. There are a lot of stored procedures in place, and with a database diagram it is simple enough 90% of the time to figure out what the stored procedure needs for arguments/returns as output. For the other 10% of the time, however, it would be helpful to have a reference. Since the DBA is a busy guy (aren't we all), it would be good to have some program which documents the stored procedures to a file so that the developers can see it without being able to access the SPs themselves. The question is, does anyone know of a good program to accomplish this? Basically what we need is something that gives the name of the SP, the argument list and the output, both with datatypes and a nullable flag.

  • How can I deploy a Perl/Python/Ruby script without installing an interpreter?

    - by Brian G
    I want to write a piece of software which is essentially a regex data scrubber. I am going to take a contact list in CSV and remove all non-word characters and such from the person's name. This project has Perl written all over it but my client base is largely non-technical and installing Perl on Windows would not be worth it for them. Any ideas on how I can use a Perl/Python/Ruby type language without all the headaches of getting the interpreter on their computer? Thought about web for a second but it would not work for business reasons.

  • php session not working (as with cookies disabled), but cookies are enabled for the domain. What oth

    - by SWilk
    Hi, I have a problem with a client, who cannot log in to our system. We have PHP-based B2B system, which uses cookies to store session-id. The client cannot log in and is redirected to the login page, without any error message. He claims he have cookies enabled in his Firefox. Also, if he had cookies disabled, my javascript would detect this and would show him an red, very descriptive error info. He does not seen anything like this. What else could have same effect on sessions like disabled cookies in browser? Are there any proxies which filters cookies? Any AV software, etc? What to look for? Our login form works for any other user without problems.

  • Proper design a Model-Controller in Cocoa?

    - by legege
    Hi, I'm trying to design a simple Cocoa application and I would like to have a clear and easy to understand software architecture. Of course, I'm using a basic MVC design and my question concerns the Model layer. For my application, the Model represents data fetched on the Internet with a XML-RPC API. I'm planning to use Core Data to represent a locally fetched version. How should the data be loaded initially? I'm reading the Cocoa Design Pattern book, and they talk about a Model-Controller that is centric to the Model. How would that be done? Thanks!

  • Get notified about the change in raw data in hard disk sector - File change notification

    I'm trying to make a software that backups my entire hard drive. I've managed to write a code for reading the raw data from hard disk sectors. However, i want to have incremental backups. For that i need to know the changed made to OS settings, file changes, everything. My question is - Using FileSystemWatcher and Inotify, will i be able to know every change made to every sector in the hard drive ? (OS settings etc) I'm coding it in C++ for linux and windows.

  • Include a unique URL in EXE

    Hi :) I want to give users of my site the ability to upload their software/hardware configuration automatically on Windows. So I'm thinking of having an EXE file download, and somehow put in that EXE a unique URL for each user. When the data is collected, the program would just posts some JSON to that URL. How can I do it? I'm most familiar with .NET platform. Tools like this do exist, for example Blizzard uses this approach for their beta test enroll. Each user downloads a slightly different EXE. TIA

    Hi, I'm an engineering student and I'm developing a simple software based on HTML, PHP and mysql. I learned this topics on w3schools. I know only the basics. I tried to search about this in this website but I found questions about PHP, MySQL and HTML radio buttons which were much more complex than I need and that I could understand. Sorry for the English. (Q1) Ex: $email=$_REQUEST['email'] , in this case the input is text, if it where like a radio button for ex: sex: male or female, how would it be? (Q2) what would be the type of this field (for exemple sex in question 1) in the database: text, int, varchar ? Thanks for the attention

  • Get DataGridView checkbox cell value?

    - by George
    Hello guys. I'm having a strange issue here. I have a 3 column datagrid that is filled by a connection with the database. So far so good. I have an extra column, of checkbox type. I need to get it's value for perfoming a bulk operation on it. Here is the catch: When all cells are selected, it works fine. But when an user selects any cell that its not the first, software gives me a object reference exception. Here is the code public List<String> GetSelected() { List<String> selected = new List<String>(); foreach(DataGridViewRow row in datagrid.rows) { if ((Boolean)row.Cells[wantedCell].Value == true) { selected.Add(row.Cells[anotherCell]); } } } I tracked down the failure to the if-test, throwing a exception, because the value of the cell is read as null. Any thougths? Thanks

  • Send mail from a Windows script

    - by Jörgen Lundberg
    I would like to send mail from a script on a Windows Server 2003 Standard Edition. I think the server setup is pretty much out of the box. The mail server is an Exchange one, and when you're on the internal network you can use plain old SMTP. I have done it from my machine with Perl, but unfortunately Perl is not available on the server. Is there an easy way of doing this from a .bat-file or any other way that doesn't require installing some additional software? Edit: Thanks for the quick replies. The "blat" thingie would probably work fine but with wscript I don't have to use a separate binary. I didn't see PhiLho's post the first time I edited and selected an answer. No need for me to duplicate the code here. Just save the script to a file, say sendmail.vbs, and then call it from the command prompt like so: wscript sendmail.vbs

  • How do I open a hardware accelarated DirectX window on a secondary screen

    - by user567021
    I'm looking to create a hardware accelarated DirectX (9 at the moment) window on a secondary screen. This screen is connected to the same graphics display as the primary screen (at least at the moment). Currently, when I try to open the window on the secondary screen based on window position or by dragging it there, CPU usage jumps by about 10%, which seems to indicate that windows is switching to a software fallback rather than the hardware accelaration. Machine is windows XP running a NVIDIA graphics card (varying cards as this runs on several machines), with the latest driver. It's also running CUDA at the same time to produce the images if that matters. Programming language is c++, manual window and message queue creation, no tookbox used at the moment to manage the GUI Thanks
