How StackOverflow does caching

Git TFS with Git 2.5 and above - Solved!

I experienced the same issues as the OP here: https://github.com/git-tfs/git-tfs/issues/845

In my case:

$ git tfs clone https://me.visualstudio.com/DefaultCollection/_versionControl $/MyProject
TFS repository can not be root and must start with "$/".
You may be able to resolve this problem.
- Try using $/C:/Program Files/Git/MyProject

The solution, courtesy of dscho: an msys2 flag that looks like the most bastardized bash syntax in the world, but apparently works. (Is this valid bash or a special msys2 thing?)

$ MSYS_NO_PATHCONV=1 git tfs clone https://me.visualstudio.com/DefaultCollection/ $/MyProject
Initialized empty Git repository in C:/Projects/MyProject/.git/

This is documented in the release notes here: https://github.com/git-for-windows/build-extra/blob/master/installer/ReleaseNotes.md#known-issues

EDIT:

You can also double up the initial quote after the $, e.g.:

$ git tfs clone https://me.visualstudio.com/DefaultCollection/ $//MyProject
Initialized empty Git repository in C:/Projects/MyProject/.git/

Doug Crockford on Monads and JavaScript

He's not the father of JavaScript, he's more the strongly opinionated caretaker.

Here is his fascinating YouTube video on JavaScript and Monads.

Here is the sourcecode: https://github.com/douglascrockford/monad

He covers four monads in the talk:

• The Identity Monad
• The Ajax Monad
• The Maybe Monad, which eliminates the possibility of a null -- very cool!
• The Promise Monad, which apparently is not agreed upon by all to be a monad

Two links he mentions

ASP.NET - don't minimize files if you're bundling!

If you've got bundling turned on, the ASP.NET bundling library will choose the already minimized instead of minimizing it at runtime. This can cause problems if you have updated the the source file -- file.js or file.css -- and you haven't remimized it.

So don't minimize the file in the IDE. Alternatively, set up some sort of automation that will automatically minimize the file or your minimized CSS and JavaScript files will be out of sync and your won't know why.

See this StackOverflow question: ASP.NET Bundling - Bundle not updating after included file has changed (returns 304 not modified)

Adding only non-whitespace changes in Git.

Sometimes it's useful to add only the non-whitespace changes because typically they'll be the meaningful content. This StackOverflow question show how to do that.

Here's the command to add everything, ignoring whitespace-only changes:

Properly serving SVG files in IISExpress

If you just edit your web.config file it will actually break your website under IISExpress. Instead, follow the instructions found here: http://tomasmcguinness.com/2011/07/06/adding-support-for-svg-to-iis-express/

• Open a console application with administrator privileges.
• Navigation to the IIS Express directory. This lives under Program Files or Program Files (x86)
• Run the command appcmd set config /section:staticContent /+[fileExtension=’svg’,mimeType=’image/svg+xml’]

Git line ending fixups revisited

I blogged about this a few years ago. I discovered how to do this when using .gitattributes, which is automatically created when you use Visual Studio to create a project that uses git as its version control system.

I have a .gitattributes file that contains (among other things) this line at the top:
The sequence of commands is the following:

First, add all changed files: Then, edit the .gitattributes file to comment out the "text=auto" line and save this file: Then issue this command to un-stage all the files. It doesn't matter whether some of the files have meaningful changes. You're not resetting or undoing any file edits, you're merely removing them from the index: Finally, restore the "text=auto" line in your .gitattributes file and save that file: You should be all set. If you issue a git status command again you should see only the files that have meaningful changes, if any.

Beyond SOLID: The Dependency Elimination Principle

http://qualityisspeed.blogspot.com/2014/09/beyond-solid-dependency-elimination.html

Last post I explained why I don't teach the SOLID design principles. Read the post for more detail, but the primary reason is that SOLID encourages heavy use of dependencies. Applying SOLID to a codebase for even a short time will yield dependencies on abstractions everywhere -- quickly producing a codebase that is unintelligible.

git cherry

My mnemonic for git cherry, i.e. git cherry upstream [head]

My quick understanding is that in many cases it means: show me everything that's NOT in upstream.

In other words:

git cherry branch-without-stuff branch-with-stuff

or

git cherry less-stuff more-stuff

or

git cherry present future

or

git cherry past present


So to see what's in develop but not yet in master, type this:

git cherry master develop

Which means, essentially, show me everything in develop that's not (yet) in master. 

Strongly-typed function callbacks in TypeScript

The question: http://stackoverflow.com/questions/14638990/are-strongly-typed-functions-as-parameters-possible-in-typescript

In TypeScript I can declare a parameter of a function as a type Function. Is there a "type-safe" way of doing this that I am missing?

My favorite answer: http://stackoverflow.com/a/24034429/53107 from Drew Noakes:

Here are TypeScript equivalents of some common .NET delegates:

{
    (item: T): void;
}

Migrate away from MSBuild-based NuGet package restore

Very nifty trick. In the end, your solution will look like the following. Note the .nuget folder has only a NuGet.Config file:

Link: http://www.xavierdecoster.com/migrate-away-from-msbuild-based-nuget-package-restore.
Here are the instructions on how to undo it: http://docs.nuget.org/docs/workflows/migrating-to-automatic-package-restore. Note: where the article says "using TFS," read it as "using version control" because the instructions also apply to Git.

Update 4/4/14: You might have to close the solution and delete any .suo files or Visual Studio will stubbornly bring back the .csproj settings that you deleted.

Update 4/9/14: This doesn't appear very stable when using version control features where you backtrack in history -- for instance to merge a feature branch. Visual Studio stubbornly resurrects the import and target tag in the project file, and killing this won't work unless you first close the solution and delete the .suo file.

I'm actually considering moving back to NuGet package restore. At least it's reliable.

Second update 4/9/14: This doesn't play well with ReSharper's cool feature where it automatically adds NuGet packages to a project instead of just a reference.

How to do a rebase with git gui

Who knew? I thought it wasn't possible, but apparently it is if you modify git config.

http://stackoverflow.com/questions/4830344/how-to-do-a-rebase-with-git-gui

Add this to the .gitconfig file in your home directory to add rebase commands to the Tools menu:

[guitool "Rebase onto..."]
    cmd = git rebase $REVISION
    revprompt = yes
[guitool "Rebase/Continue"]
    cmd = git rebase --continue
[guitool "Rebase/Skip"]
    cmd = git rebase --skip
[guitool "Rebase/Abort"]
    cmd = git rebase --abort
[guitool "Pull with Rebase"]
    cmd = git pull --rebase

AngularJS Dependency Injection Cheatsheet

I finally get it. A cheatsheet for AngularJS dependency injection is as follows:

var somethingController = angular.module('What_it_provides', ['what', 'it', 'depends', on']);

somethingController.controller('Name', ['$what', '$it', 'depends', 'on', function('$what', '$it', 'depends', 'on') {
    // implementation, which returns a value, presumably.
}];

The core Angular dependencies (those in ng) are not listed in the angular.module() call, but they are listed in the .controller() call and in the function signature.

The 'What_it_provides' name seems to be used by the dependency injection framework in calls to angular.module(), i.e. the provider name, e.g. SomethingService. But the name would just be Something.
The 'Name' name seems to be used in parameter lists of implementation functions and in calls to controller(), factory(), etc.

See the example from the AngularJS tutorial step 11.

MVC3 app_code directory

I just found out from K. Scott Allen’s MVC3 training video on Pluralsight that the app_code directory in MVC3 is alive and well. Basically the Razor helpers here are pre-compiled and can be accessed globally in the application.

Apparently the usage in a Razor page is as follows:

    @Common.Script(“myscript.js”, Url)

Note to self: compare and contrast with shared “editor” partial views.

Note: I composed this post with Windows Live Writer 2011 but it doesn’t seem to play well with Blogger’s own editor. ¡Qué pena!

MVC3 ModelState and overwriting model properties

I will expand this later, I swear.

Caution: when you are using strongly typed models in MVC3 and you modify a property of the model in an Action, that property will get discarded when you create the view unless you clear the ModelState first. When building the view, the model fields are overwritten with values from ModelState, so clearing the ModelState prevents this.

UPDATE 11/10/2011:
This only applies to values passed in via a POST (or a GET?) that you're attempting to override by changing the corresponding fields in the view model.

RegExes for replacing MVC3 hard-coded hrefs with @Url.Content hrefs

I'm posting this here mainly as a memory aid for myself.

My app is sprinkled with lots of links like this:

    <script src="../../Scripts/jquery-ui-1.8.11.min.js" type="text/javascript"></script>

I'd like them to look like this, since NuGet seems to be cognizant of such references and apparently changes them on upgrades:

    <script src="@Url.Content("~/Scripts/jquery-ui-1.8.11.min.js")" type="text/javascript"></script>

So the following search and replace with RegExes will work:

Find what:	"\.\./\.\.{/[^"]*}"
Replace with:	"@Url.Content("~\1")"

Include the quotes, and be sure to select "Use regular expressions."

Note that the consistent relative path "../../" must be changed as per your circumstances.

UPDATE on 11/2/11:

This "Replace With" parameter might be better:

"@Href("~\1")"

UPDATE on 11/22/11:
Now, according to this article, I see that Url.Content is supposed to be better anyway.

WCF Notes

To discover WCF services, make sure that https is turned off. This is done in two places, apparently:

• In the binding, on the Security tab, Mode property, make sure the property is not set to “Transport”.
• In the service behaviors, serviceMetadata, make sure httpsGetEnabled is set to false and that httpsGetEnabled is set to true.

When you’re done, turn those things back on again.

    {

How to replace all automatic properties of string type with a string type which is never null

I have to do this in a piece of code, so I'm recording this here for my future reference.

In Visual Studio's Find and Replace dialog, type the following in the "Find what:" field:
public string \{:i\} \{ get; set; \}

Type this into the "Replace with" field:
private string _\1;\npublic string \1 \{\nget \{ return _\1 ?? ""; \}\nset \{ _\1 = value; \}\n\}

This pattern of performing a test in the getter versus the setter guarantees that it will never be null, and is the pattern used in the TextBox web control's Text property.

Afterwards you'll want to reformat the code, and possibly rename the backing fields, e.g. _FirstName, to be more camel-cased instead of being Pascal-cased(-like), e.g. _firstName instead of _FirstName.

Setting the Text of a ListControl in ASP.NET

If you try the following, it should set the visible text of the dropdown control in question, right?

    listControl.Text = "4 Year College";

Well, unfortunately, no! The "Text" property is named that way for consistency across all ASP.NET controls and refers to the form value that is passed to the server when the page is submitted. So unfortunately for me, the "Text" property silently rejected my attempt to set it and the page did not work.

You may be asking yourself why I am trying to set the visible text and not the value of the control. The reason is that the application I'm working on receives the displayed text from a web service and not the value that is passed in the form variables. Why not create a dictionary, look up the the text string in the dictionary, and pass that to the control?

The answer? I already have a dictionary. It's called the SELECT control itself. The generated HTML for my control is, say, the following:


This control is essentially a dictionary of key-value pairs: the key is the value attribute of the option tag, and the value is the visible text that is displayed for the given item in the dropdown list. So in the spirit of Don't Repeat Yourself (DRY), I wrote a extension function to allow me to set not just the value but also the text. I give you ListControlExtensions.cs:


Here's a typical usage. In this particular scenario, my data should be scrubbed, but if not I log a warning:

IIS Express FAQ : IIS Express : Microsoft Web Platform : The Official Microsoft IIS Site

After I relocated an IIS express application, it stopped working. Even though I re-registered it with Visual Studio, it appeared "stuck" in its old location. The problem is that Visual Studio doesn't tell you that it hasn't really done anything at all when it claims that it's successfully registered your app after you've moved it. After reading this FAQ I was able to delete the broken site registration and then re-add it in Visual Studio. To fix my problem, I ran "%userprofile%\documents\IISexpress\config" from the Windows start menu, did a ctrl-F to find the application name, and simply deleted the configuration node.

IIS Express FAQ : IIS Express : Microsoft Web Platform : The Official Microsoft IIS Site: "Q: Does IIS Express use the same configuration system as IIS 7.x?

A: Yes, IIS Express uses the same applicationhost.config and web.config files supported by IIS 7.x. The key difference is that with IIS Express, the configuration is maintained on a per-user basis. In particular, whereas IIS has a global “applicationhost.config” file, IIS Express maintains a user-specific “applicationhost.config” file in the %userprofile%\documents\IISexpress\config” folder. This lets a standard user run IIS Express and also lets multiple users work on the same machine independently, without conflicting with each other. Some settings require Administrator user rights to set and modify (see question above about running as a standard user)."

Reimplementing LINQ to Objects: Part 43 - Out-of-process queries with IQueryable - Jon Skeet: Coding Blog

Interesting stuff throughout, but here's the summary at the end:

"This was really a whistlestop tour of the "other" side of LINQ - and without going into any of the details of the real providers such as LINQ to SQL. However, I hope it's given you enough of a flavour for what's going on to appreciate the general design. Highlights:

• Expression trees are used to capture logic in a data structure which can be examined relatively easily at execution time
• Lambda expressions can be converted into expression trees as well as delegates
• IQueryable and IQueryable form a sort of parallel interface hierarchy to IEnumerable and IEnumerable - although the queryable forms extend the enumerable forms
• IQueryProvider enables one query to be built based on another, or executed immediately where appropriate
• Queryable provides equivalent extension methods to most of the Enumerable LINQ operators, except that it uses IQueryable sources and expression trees instead of delegates
• Queryable doesn't handle the queries itself at all; it simply records what's been called and delegates the real processing to the query provider"

{E53F8FEA-EAE0-44A6-8774-FFD645390401};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}

The perils of using Func instead of Expression in an IQueryable

This is sort of a LINQ 101 thing, but I haven't had much of an opportunity to use LINQ to SQL yet, believe it or not.

I learned the hard way: when using IQueryable against a database, any predicates handed around should be  Expression<func<type, bool>> instead of just Func<type, bool>. Func<type, bool> is evaluated in memory! That means that the entire table is fetched from the database, then filtered in memory. Bad, bad, bad!

Michael C. Kennedy's Weblog - 11 Killer Open Source Projects I Found with NuGet

Michael C. Kennedy's Weblog - 11 Killer Open Source Projects I Found with NuGet: "11 Killer Open Source Projects I Found with NuGet

Wednesday, January 19, 2011 5:18:17 PM (Pacific Standard Time, UTC-08:00)
So maybe I'm late to the party, but I recently started playing with NuGet. It's a killer new way to find, install, maintain, and manage references to open source libraries in Visual Studio 2010. Plenty of people have written about it (Phil Haack and Scott Hanselman for example). Let's just say you should learn about NuGet if you don't know it already.

What I want to talk about is all the cool open source projects I found just by flipping through the pages of the NuGet directory in the Visual Studio 'Add Library Package Reference' dialog."

Kill That Util Class!

According to him, a static "Helper" or "Util" class is an anti-pattern in a language like C#, which has extension methods, so kill it!

Interesting take. I'd agree that it can greatly reduce the incidence of such classes, yes.

Kill That Util Class!: "According to me a Util class is a sign of misplaced responsibility (a missed opportunity to see an abstraction fulfilling that behavior), resulting in poor OO-ness. Often, utility methods are placed in classes with only static methods and disallow instance creation with new. If you listen carefully, these Utility classes cry out loud, telling you to find a home for the homeless child!"

The protocol-relative URL

From Paul Irish: The protocol-relative URL: "There's this little trick you can get away with that'll save you some headaches:

<img src="//domain.com/img/logo.png">

If the browser is viewing that current page in through HTTPS, then it'll request that asset with the HTTPS protocol, otherwise it'll typically* request it with HTTP. This prevents that awful "This Page Contains Both Secure and Non-Secure Items" error message in IE, keeping all your asset requests within the same protocol."

Algorithmia Source Code released on CodePlex - Frans Bouma's blog

This code library is used by the LLBLGen Pro 3.0 designer, so it's stable and tested.

The undo/redo looks intriguing.

Algorithmia Source Code released on CodePlex - Frans Bouma's blog: "One of the main design goals of Algorithmia was to create a library which contains implementations of well-known algorithms which weren't already implemented in .NET itself. This way, more developers out there can enjoy the results of many years of what the field of Computer Science research has delivered. Some algorithms and datastructures are known in .NET but are re-implemented because the implementation in .NET isn't efficient for many situations or lacks features. An example is the linked list in .NET: it doesn't have an O(1) concat operation, as every node refers to the containing LinkedList object it's stored in. This is bad for algorithms which rely on O(1) concat operations, like the Fibonacci heap implementation in Algorithmia. Algorithmia therefore contains a linked list with an O(1) concat feature."

InfoQ: Testing Techniques for Applications With Zero Tests

InfoQ: Testing Techniques for Applications With Zero Tests: "Agile techniques recommend having adequate unit and acceptance tests to build a robust test harness around the application. However, in the real world, not all applications are fortunate enough to have a test harness. In an interesting discussion on the Agile Testing group, members suggested ways to test applications which do not have any automated tests."

A six-step approach is outlined.

InfoQ: How To Do Large Scale Refactoring

InfoQ: How To Do Large Scale Refactoring: "Refactoring by definition means changing the internal structure of a program without modifying its external functional behavior. This is mostly done to improve the non-functional attributes of the program thus leading to improved code readability and maintainability. However, refactoring on a large scale often gives jitters to even seasoned Agilists. The Agile community discussed some ways of handling the large scale refactoring."

Strangling was mentioned as a good approach.

This article also discusses the Mikado Method, which is kind of interesting.

So You Want to Interview for a Senior Developer Position…. « If & Else

So You Want to Interview for a Senior Developer Position…. « If & Else - "When my last company imploded in an epic fiery crash, I quickly found myself moving from Nashville, TN to Chattanooga, TN to become part of a growing team that was recruiting for several senior positions. While I’m the most recent full-time senior member to come aboard, we are still actively seeking senior level talent. Since August, I have sat through countless phone screens, phone interviews and a handful of in-person interviews as part of that search. To say that it has been eye-opening and disappointing would be an understatement. The opinions and observations I’m about to share are my own – and do not reflect the views of my employer (an employer who has been gracious and generous not only to me, but to many candidates, including the ones they’ve flown in from across the country, covering the cost of travel). I don’t intend for this post to be an exhaustive treatment of “what to ask senior architect or developer candidates in an interview” – consider it more a discussion of “the minimum requirements for someone (including you) interviewing for a senior developer or architect position”. I genuinely do not mean to come across as the ‘grumpy, impossible to please’ developer/architect. My frustration will be evident, though, so at least that’s out in the open…."

Jurassic - A Javascript Compiler for .NET

Might this come in handy some day?

Jurassic - A Javascript Compiler for .NET: "What is Jurassic?

Jurassic is an implementation of the ECMAScript language and runtime. It aims to provide the best performing and most standards-compliant implementation of JavaScript for .NET. Jurassic is not intended for end-users; instead it is intended to be integrated into .NET programs. If you are the author of a .NET program, you can use Jurassic to compile and execute JavaScript code.

Features

• Supports all ECMAScript 3 and ECMAScript 5 functionality
  
• Simple yet powerful API
  
• Compiles JavaScript into .NET bytecode (CIL); not an interpreter
  
• Deployed as a single .NET assembly (no native code)
  
• Basic support for integrated debugging within Visual Studio
  
• Uses light-weight code generation, so generated code is fully garbage collected"

FsCheck: A random testing framework

I'll have to check this out.

FsCheck: A random testing framework: "FsCheck is a tool for testing .NET programs automatically. The programmer provides a specification of the program, in the form of properties which functions, methods or objects should satisfy, and FsCheck then tests that the properties hold in a large number of randomly generated cases. While writing the properties, you are actually writing a testable specification of your program. Specifications are expressed in F#, C# or VB, using combinators defined in the FsCheck library. FsCheck provides combinators to define properties, observe the distribution of test data, and define test data generators. When a property fails, FsCheck automatically displays a minimal counter example."

A few thoughts on jQuery templating with jQuery.tmpl | Encosia

I have to create some email templates for use by (gulp) classic ASP. I thought I'd do a bit of reading on templates in order for (1) my template tag convention to be inspired by existing templates and thus be future-friendly, and (2) perhaps if I'm lucky, to find a template I can actually use on the server itself. (PURE, mentioned below, might be a candidate.)

A few thoughts on jQuery templating with jQuery.tmpl | Encosia: "I spent some quality time with Dave Reed’s latest revision of John Resig’s jQuery.tmpl plugin recently, migrating a small project from jTemplates. Since both the jQuery team and Microsoft team have requested feedback on jQuery.tmpl, I decided to write about my experience using it (as I am wont to do with these templating proposals).
Overall, jQuery.tmpl is a great step in the right direction. It’s small, it’s simple, and it’s fast. Overloading append() to allow the append(Template, Data) syntax is phenomenal. That approach feels more like idiomatic jQuery than anything else I’ve used, including jTemplates."

He mentions that it lacks composability, but this article is from May. Has Microsoft added it since then?

From the comments, a few more libraries to consider:

Spark - the new hotness, apparently. Included with the latest Microsoft MVC, if I'm not mistaken.

PURE - seems more decoupled than the others, but at first glance it doesn't seem to support to ubiquitous "${}" convention.

I'm still reading. This is kind of a brain dump for further research at some point when I have more time (i.e. when hell freezes over).

Javascript Libraries and ASP.NET: A Guide to jQuery, AJAX and Microsoft - Articles - MIX Online

Javascript Libraries and ASP.NET: A Guide to jQuery, AJAX and Microsoft - Articles - MIX Online: "When Microsoft announced they would begin providing official support for jQuery, few of us realized how profoundly that announcement would eventually impact client-side development on the ASP.NET platform. Since that announcement, using jQuery with ASP.NET has moved from the obscure, to a central role in ASP.NET MVC’s client-side story, and now to the point of potentially superseding ASP.NET AJAX itself."

NET jQuery Extensions at GitHub

Highlights include:
"Templating – Previously referred to as jQuery.tmpl or jQuery-tmpl, the jQuery Templating feature was Microsoft’s first foray into working with the jQuery team and community. Though its inclusion in jQuery isn’t planned until jQuery 1.5 is released, you can begin using it in plugin form immediately. That plugin is currently available on GitHub: http://github.com/jquery/jquery-tmpl"
and
"Data Linking – The next feature that may be a precursor to more official things to come is the jQuery-datalink plugin, which is also available on GitHub: http://github.com/nje/jquery-datalink. With this plugin, you can “link” JavaScript objects together so that they remain synchronized when changes are made to one or both of them. The canonical example of this is linking a JavaScript object’s properties to corresponding fields in a form, to eventually automate tasks such as change tracking and submission."

More from Scott Guthrie:
"jQuery Templates
The jQuery Templates plugin enables you to create client templates. For example, you can use the jQuery Templates plugin to format a set of database records that you have retrieved from the server through an Ajax request.
You can learn more about jQuery templates by reading my earlier blog entry on jQuery Templates and Data-Linking or by reading the documentation about it on the official jQuery website. In addition, Rey Bango, Boris Moore and James Senior have written some good blog posts on the jQuery Templates plugin:

• Not Using jQuery JavaScript Template? You’re Really Missing Out
• jQuery JavaScript Templates Tutorial: Nesting Templates
• Introducing jQuery Templates
• jQuery Templates in the Wild
• Web Camps Demos: Adding jQuery to the ASP.NET MVC Music store

When the next major version of jQuery is released -- jQuery 1.5 -- jQuery Templates will be included as a standard part of the jQuery library."

jQuery Grid Recommendations - Stack Overflow

jQuery grid reference from StackOverflow:

jQuery Grid Recommendations - Stack Overflow: "The best entries in my opinion is Flexigrid and jQuery Grid (1st & 2nd in list). The others are included for completeness.

Flexigrid: http://flexigrid.info/
jQuery Grid: http://www.trirand.com/blog/
jqGridView: http://plugins.jquery.com/project/jqGridView
Ingrid: http://reconstrukt.com/ingrid/
SlickGrid http://github.com/mleibman/SlickGrid
I like the jQuery Grid (#2 above) better than Flexigrid mostly because it supports editable cells, and has very good documentation and samples on the website."
