How StackOverflow does caching

StackOverflow went down for a few hours earlier today, so I was able to read up on how they do caching here: http://meta.stackexchange.com/questions/69164/does-stack-exchange-use-caching-and-if-so-how

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

Great article. There are several ways of doing it, including the Twitter way, which handles infinite feeds in real-time scenarios using cursors.

Cool Visual Studio Extensions From Mads Kristensen

Mads, the author of the essential Web Essentials extension for Visual Studio, has created a number of other plugins and extensions as well. Here's a link to two blog posts by him describing these extensions.

Learn F# or Haskell?

Here's a side-by-side comparison of ML dialects, of which F# is one, with Haskell:

ML Dialects and Haskell: SML, OCaml, F#, Haskell - Hyperpolyglot

Then there are the various "99 Bottles" F# implementations. Interestingly, Don Syme's is one of the longer version. He is the creator of F# and arguably knows it the best.

Here's the Haskell version:

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:

git diff -w | git apply --cached --ignore-whitespace

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:

interface Action<T>
{
    (item: T): void;
}

interface Func<T,TResult>
{
    (item: T): TResult;
}

Renaming a remote branch in Git

I don't quite understand this, but I'll post it here anyway. It comes from StackOverflow user sschuberth.

git push <remote> <remote>/<old_name>:refs/heads/<new_name> :<old_name>

Example:

git push origin origin/hotfix/Cant-load-assembly.0:refs/heads/feature/Fix-cant-load-assembly :hotfix/Cant-load-assembly.0

Git - Refreshing a repository after changing line endings

Who knew? My repositories sometimes contain problematic commits that are just about fixing up line endings, but here's a solution to that from GitHub. (I haven't tested it yet.)

Refreshing a repository after changing line endings

Here's the StackOverflow post from which GitHub gets their answer. There's also something interesting about removing the index, which I never knew about.

My quick and dirty way of doing it. The target tag is the most relevant part if you're already using NLog.
