  • Are there any GOOD Chef, Chef-Server and Chef-Client tutorials out there?

    - by btelles
    Hi there, Chef from Opscode seems to be really useful for configuring servers and such, but trying to follow their documentation is a little difficult. Some terms are defined after they are used, and definitions sometimes reference new terms that you haven't yet encountered. Anyone know of any GOOD tutorials/walk-throughs for getting a good understanding of Chef, Chef-Server and Chef-Client? I remember seeing one video presentation online, but it barely scratched the surface.

  • How to find out if an object is of <type> or a decendant of <type>

    - by Vaccano
    I have the following code: foreach (var control in this.Controls) { } I want to do something like control.Hide() in there. But the items in the this.Controls collection are not of type Control (they are Object). I can't seem to remember the safe way to cast this to call hide if it is really of type Control and do nothing otherwise. (I am a transplanted delphi programmer and I keep thinking something like control is Control.)

  • Gradient colors in Internet Explorer

    - by Jeremy
    I know that Internet Explorer has some proprietary extensions so that you can do things like create divs with a gradient background. I can't remember the element name or it's usage. Does anyone have some examples or links?

  • MVC Entity Framework: Cannot open user default database. Login failed.

    - by Michael
    This type of stuff drives me nuts. I'm having trouble finding the exact issue that I'm having, maybe I just don't know the terminology. Anyway, I had a working website using MVC and Entity Framework, but then I coded an error in a partial view page (ascx). Then all of a sudden I started to get this message. Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITY\SYSTEM' I've found plenty of suggestions about opening SQL Server Management Studio, Double Click on Security, Double Click on Logins, Double click on NT AUTHORITY\SYSTEM and then double click on User Mapping. In this view I'm suppose to check the box for my database so that this user is mapped to this login. However, since I created my database in Visio Studio 2008 as part of my solution, it doesn't show up to allow me to click on it. So what do I do now? What drives me nuts is that everything was working fine. I was using my computer name to access the website and everything was working fine until the coding error. I've fix the error but still getting the error. I should also mention that this error started yesterday too around the same time but later cleared itself up. If I use localhost to access the site, it works just fine. IIS7 configuration for my website: Application Pool = DefaultAppPool Physical Path Credentials Logon = ClearText With in connection strings. I do see the one for my database in this solution. Entry Type is local metadata=res://*/Models.DataModel.csdl|res://*/Models.DataModel.ssdl|res://*/Models.DataModel.msl; provider=System.Data.SqlClient; provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFBall.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True" And somewhere I remember changing the identity from Network Service to LocalSystem. Because when I first stared I was getting this same message, but I changed this value and it started working. I saw that suggested somewhere too but I do not recall. Wait I remember now, I believe in IIS7, under Application Pools, DefaultAppPool identity is set to LocalSystem. Additional things I've tried. Restart the computer Recycle the application pool. Antivirus isn't running. Any help would be appreciated. Thank you in advance.

  • C# equivalent of NaN or IsNumeric

    - by johnc
    This seems like a fairly simple question, and I'm surprised not to have required it before. What is the most efficient way of testing a string input is a numeric (or conversely Not A Number). I guess I can do a Double.Parse or a regex (see below) public static bool IsNumeric(this string value) { return Regex.IsMatch(value, "^\\d+$"); } but I was wondering if there was a implemented way to do it, such as javascript's NaN() or IsNumeric() (was that VB, I can't remember).

  • Website Listing Commonly Used Ruby Gems, Including Alternatives

    - by ottobar
    I know that I've seen this site before, but cannot remember it for the life of me. Basically, it is a listing of commonly used gems, like XML parsing or ORM libraries. For the ORM case, it lists ActiveRecord, DataMapper, and the like, stating the advantages and disadvantages of each. Does anyone know what this site is? I've googled and have not been able to find it.

  • Mustache vs other engines. Maybe I should use another template engine?

    - by marcioAlmada
    I'm passing an object to mustache and this object has a method with one parameter. Is something like this possible with Mustache and PHP? {{object.method(parameter)}} If it gets too laborious to achieve this with Mustache, what template engine would you recommend? Remember I need to pass parameters to object methods while in the view context (like we do with helpers). The nearest as possible to mustache syntax is welcome.

  • get pure text form odt file in console

    - by naugtur
    I am looking for a small linux tool that would be able to extract text from odt file. It just needs to be human-readable and it can have problems with complicated objects etc. It's almost a duplicate of this question but I need it to be small and have no dependencies on OpenOffice or X server I remember having a 1MB MS-DOS program that could render .doc files quite readibly (with some weird markup getting through from time to time), so i expect it to be possible in the linux world too ;)

    Hi! Can someone confirm a save process misbehaviour in the AppModel for the method beforeSave( )? This method doesn't seem to be executed before saving a data set. I can remember of reading something about a bug in a current version (btw, I am using 1.3.1). Best regards, Beendikt

  • Implementing a virtual file system in .NET

    - by Charlie Somerville
    A while back a found a great-looking framework that allowed .net developers to implement a virtual file system. I thought I had bookmarked it, but it seems I haven't. Does anyone know any frameworks for doing this? EDIT: Here's a hint... It had a catchy, short name and it's own domain. Sorry, that's all I can remember :p

  • Detecting struckout text in a cell using JExcelApi

    - by Geo
    I need to detect whether the text within a cell is struck out or not. I'm using this: Cell cc = sheet.getCell("B1"); CellFormat format = cc.getCellFormat(); System.out.println(format.getFont().isStruckout()); but I remember I read somewhere that CellFormat is deprecated and CellFeatures should be used instead. How could one find out whether a text is struck out using CellFeatures?

  • What is the funniest bug you've ever experienced?

    - by friol
    I remember testing a geographical data normalizer written in Java that had concurrency problems. So, when you tried to normalize a city (say "Rome") and another guy did that too (say "New york"), you would get the other guy's data normalized ("NEW YORK") instead of your query. What's the bug that mostly made you smile in your career?

  • Find the version of an installed npm package

    - by Laurent Couvidou
    How to find the local version of an installed node.js/npm package? This prints the version of npm itself: npm -v <package-name> This prints a cryptic error: npm version <package-name> For some reason, probably because of the weird arguments ordering, or because of the false positives mentioned above, I just can't remember the proper command. So this question is a note for self that might help others.

  • Passing a DataTable into a Stored Procedure. Is there a better way?

    - by punkouter
    Can A datatable somehow be passed into SQL Server 2005 or 2008 ? I know the standard way seesm to be passing XML to a SP. And a datatable can easily be converted to XML somehow to do that. What about passing a .NET object into a SP ? Is that possible ? I remember hearing about SQL and CLR working together in 2008 somehow but I never understood.. Maybe that means you can refer to .NET objects within a Stored Procedure ?

Remember that the UTC-offset is not the same all year because of winter/summer-time.

  • What are the destructive commands in git?

    - by Riccardo Galli
    I read that Git mainly add informations about the repository's history, trying to remember every change made, but that there are also commands that make irreversible changes. What are the commands that I should really pay attention to and avoid to use wrongly because there is not turning back?
