  • Best way to learn SQL Server

    - by Jason Baker
    So I'm getting a new job working with databases (Microsoft SQL Server to be precise). I know nothing about SQL much less SQL Server. They said they'd train me, but I want to take some initiative to learn about it on my own to be ahead. Where's the best place to start (tutorials, books, etc)? I want to learn more about the SQL language moreso than any of the fancy point and click stuff.

  • Is it worth moving from stored procedures to linq ?

    - by Josef
    I'm looking at standardizing programming in an organisaiton. Half uses stored procedures and the other half Linq. From what i've read there is still some debate going on on this topic. My concern is that MS is trying to slip in it's own proprietry query language 'linq' to make SQL redundant. If a few years back microsoft had tried to win customers from oracle and sybase with their MSSQL database and stated that it didn't use SQL by their own proprietry query langues ie linq. I doubt many would have switched. I believe that is exactly what is happening now by introducting it into the applicaiton business layer. I have used MS for many years but there is one gripe that I have with them and that is that they change their direction a lot. By a lot I mean new releases of .net, silverlight etc are more than 30% different from previous version. So by the time you become productive a new release is on the way. As things stand now a web developer using .net would need to know either vb.net or c#, xml, xaml,javascript,html, sql and now linq. That doesn't make for good productivity in my books. My concern is that once we all start using linq MS will start changing it between releases. and it will become an ever changing landscape. I believe that 'linq to sql' has already been deprecated. At leas with SQL we are dealing with a more stable and standardized language. Are we looking at a programming revolution or a marketing campaign? As far as I know other languages like Cobol have stayed the same for years. A cobol program from 20 years ago could pick up todays code and start working on it. Could a Vb3 person work on a modern .net web app ? Would these large changes need to be made if the underlying original foundation had been sound ? I worry about following MS shaking roadmap with it's deadends and double backs. are there any architects out there who feel the same ? regards Josef

  • Why did you learn C?

    - by Dinah
    For those who know or are learning C: Why did you choose to learn C? Was a school or job requirement? Curiosity? Boredom? Personal growth? ... I'm especially curious to know how many learned it to better understand the inner workings of their language of choice. If this is your reason, was it prompted by Joel's suggestions?

  • Windows Media Player Device Sync in VB.NET using WMPLIB

    - by Jack Hayter
    The MSDN documentation for WMPLIB states that syncing to device is not supported in .NET programming, only C++. Is there, however, a simple wrapper class or DLL that can be used to interface between a .NET program and the nescessary C++ code? Or is there a better way to sync files to a device using VB.NET? Are all devices suited/compatible with just a simple filesystem.copyfile ?

  • Implement Semi-Round-Robin file which can be expanded and saved on demand

    - by ircmaxell
    Ok, that title is going to be a little bit confusing. Let me try to explain it a little bit better. I am building a logging program. The program will have 3 main states: Write to a round-robin buffer file, keeping only the last 10 minutes of data. Write to a buffer file, ignoring the time (record all data). Rename entire buffer file, and start a new one with the past 10 minutes of data (and change state to 1). Now, the use case is this. I have been experiencing some network bottlenecks from time to time in our network. So I want to build a system to record TCP traffic when it detects the bottleneck (detection via Nagios). However by the time it detects the bottlenecking, most of the useful data has already been transmitted. So, what I'd like is to have a deamon that runs something like dumpcap all the time. In normal mode, it'll only keep the past 10 minutes of data (Since there's no point in keeping a boat load of data if it's not needed). But when Nagios alerts, I will send a signal in the deamon to store everything. Then, when Naigos recovers it will send another signal to stop storing and flush the buffer to a save file. Now, the problem is that I can't see how to cleanly store a rotating 10 minutes of data. I could store a new file every 10 minutes and delete the old ones if in mode 1. But that seems a bit dirty to me (especially when it comes to figuring out when the alert happened in the file). Ideally, the file that was saved should be such that the alert is always at the 10:00 mark in the file. While that is possible with new files every 10 minutes, it seems like a bit dirty to "repair" the files to that point. Any ideas? Should I just do a rotating file system and combine them into 1 at the end (doing quite a bit of post-processing)? Is there a way to implement the semi-round-robin file cleanly so that there is no need for any post-processing? Thanks Oh, and the language doesn't matter as much at this stage (I'm leaning towards Python, but have no objection to any other language. It's less of an issue than the overall design)...

  • Parser generator for inline documentation

    - by Leonth
    To have a general-purpose documentation system that can extract inline documentation of multiple languages, a parser for each language is needed. A parser generator (which actually doesn't have to be that complete or efficient) is thus needed. http://antlr.org/ is a nice parser generator that already has a number of grammars for popular languages. Are there better alternatives i.e. simpler ones that support generating parsers for even more languages out-of-the-box?

  • WML And Downloads

    - by Nathan Campos
    I'm now playing with WML and WMLScript, but I'm doing a site that will have some content to download(some txt, doc, bmp, mpg, avi and jpg files), but some of my friends(that never developed in this language, just used the technology on the beginning) said that it's impossible. Then here are my questions: It's possible? How to do it? Remember that I'm using PHP combined with WML.

  • using Java interfaces

    - by mike_hornbeck
    I need to create interface MultiLingual, that allows to display object's data in different languages (not data itself, but introduction like "Author", "Title" etc.). Printed data looks like this : 3 grudnia 1998 10th of June 1924 Autor: Tolkien Tytul: LoTR Wydawnictwo: Amazon 2010 Author: Mitch Albom Title: Tuesdays with Morrie Publishing House: Time Warner Books 2003 37 360,45 PLN 5,850.70 GBP 3rd of December 1998 10th of June 1924 Author: Tolkien Title: LoTR Publishing House: Amazon 2010 Author: Mitch Albom Title: Tuesdays with Morrie Publishing House: Time Warner Books 2003 37,360.45 GBP 5,850.70 GBP Test code looks like this : public class Main { public static void main(String[] args){ MultiLingual gatecrasher[]={ new Data(3,12,1998), new Data(10,6,1924,MultiLingual.ENG), new Book("LoTR", "Tolkien", "Amazon", 2010), new Book("Tuesdays with Morrie", "Mitch Albom", "Time Warner Books",2003, MultiLingual.ENG), new Money(1232895/33.0,MultiLingual.PL), new Money(134566/23.0,MultiLingual.ENG), }; for(int i=0;i < gatecrasher.length;i++) System.out.println(gatecrasher[i]+"\n"); for(int i=0;i < gatecrasher.length;i++) System.out.println(gatecrasher[i].get(MultiLingual.ENG)+"\n"); } } So i need to introduce constants ENG, PL in MultiLingual interface, as well as method get(int language) : public interface MultiLingual { int ENG = 0; int PL= 1; String get(int lang); } And then I have class Book. Problem starts with the constructors. One of them needs to take MultiLingual.ENG as argument, but how to achieve that ? Is this the proper way? : class Book implements MultiLingual { private String title; private String publisher; private String author; public Book(String t, String a, String p, int y, MultiLingual lang){ } Or should I treat this MultiLingual.ENG as int variable , that will just change automatically constants in interface? Second constructor for book doesn't take MultLingual as argument, but following implementation is somehow wrong : public Book(String t, String a, String p, int y){ Book someBook = new Book(t, a, p, y, MultiLingual m); } I could just send int m in place of MultiLingual m but then I will have no control if language is set to PL or ENG. And finally get() method for Boook but I think at least this should be working fine: public String get(int lang){ String data; if (lang == ENG){ data = "Author: "+this.author+"\n"+ "Title: "+this.title+"\n"+ "Publisher: "+this.publisher+"\n"; } else { data = "Autor: "+this.author+"\n"+ "Tytul: "+this.title+"\n"+ "Wydawca: "+this.publisher+"\n"; } return data; } @Override public String toString(){ return ""; } }

  • Google and Mirror Websites

    - by Roberto Aloi
    Which is the best way to manage a website with one or more mirrors so that: Google don't consider it as "dupicated content" The website is correctly indexed No inconsistencies or duplicated information are present in Google Analytics The Google webmaster guidelines in general are respected NOTE: I'm not sure if I should ask this question here or in ServerFault. It looks a bit in the middle between programming and server administration. Let me know if you think ServerFault represent a more appropriate place for this and I'll move it. Thanks.

  • RTS AI: where to start?

    - by awegawef
    I'd like to begin tinkering around with an RTS AI, but I'm having trouble finding a good environment to work with, ie a game that has been already created. I have looked at Spring RTS and Bos Wars, but they don't seem to be conducive to creating simple examples. I am not totally opposed to writing my own game environment, it would just take a long time. Does anyone have a suggestion as to how I can get my feet wet without programming my own game?

  • JSON Feed Appears to be XHR when it should be JS

    - by Oscar Godson
    I don't get why it'd doing this with the 2nd feed (appearing as a XHR call rather than just JS [looking at it in Firefox/Firebug]). The 2nd feed has the exact same MIME type as Flickr's JSON feed, yet the PortlandOregon.gov one shows as XHR and i get a NULL callback when using $.getJSON and if i use $.ajax with a 'json' or 'jsonp' type i get nothing at all. If i do the Flickr one i get the normal "[object Object]" callback. Whats going on? Please help! This has been such a headache for about a week. And i have authorization to change the feed, but i have to request the change, so if anyone knows for absolute sure let me know that!
