Open Source but No License

I have posted some small projects of mine on GitHub, mainly so that prospective employers can appreciate my skills. I am not quite ready to truly open source them, so I published them under "No License".  This means that I remain the exclusive copyright holder of these creative works, and nobody else can use, copy, distribute, or modify them in any way, shape or form. More information here: choosealicense.com - "No License" (https://choosealicense.com/no-permission/).

Pretty much the only thing one can legally do with these creative works is view their source code and admire it.

GitHub says that one can also make a copy of my projects, (called fork in GitHub parlance,) but I am not sure what one would gain from doing that, because you cannot legally do anything with the forked code other than view it and admire it.  Even more information here: Open Source SE - GitHub's “forking right” and “All rights reserved” projects (https://opensource.stackexchange.com/q/1154/10201)

(Okay, if you compile any of my projects and run it once or twice in order to check it out, I promise I will turn a blind eye.)

If you want to do anything more with any of these projects, please contact me.

On JUnit's random order of test method execution

This is a rant about JUnit, or more precisely, a rant about JUnit's inability to execute test methods in natural method order. 

Definition: Natural method order is the order in which methods appear in the source file.

What is the problem?

Douglas Crockford talking nonsense

Here is Douglas Crockford,
talking patent nonsense about Java and about exceptions,
neither of which he understands, obviously.

On Code Craftsmanship

I will try to make a list of items here, but I could probably write a book on this.

Tablecloth

Deerlux 100% Pure Linen Washable Tablecloth Solid Color from target.com

A short, high-tech, sci-fi, horror story written on the evening of January 25, 2018.

There was a guy who got in a quarrel with his girlfriend, and she kicked him out of her apartment without even throwing his clothes out the window for him. So there he was, naked on the street, not knowing what to do. Out of necessity, he grabbed a tablecloth from a restaurant, draped himself with it, and started to go home, trying to look as if everything was normal and under control.

Simplicity

Simplicity is the art of hiding complexity

Disabling the Group Policy Client Service in Windows

Scenario:

• You are an administrator on your machine.
• Your machine is either:
• In a Windows Domain, and you don't want the domain admins messing with it.
• Not in a Windows Domain, and you just don't want useless services running.

In this case, what you probably want to do is prevent the Group Policy Client Service from running on your machine.  Unfortunately, that's not a straightforward task to accomplish, because if you go to "services" and try to stop or disable this service, Windows doesn't let you.

Here is how to do it.

These instructions have worked for me on Windows 7; they might also work on other versions of windows.  If there is anything in these instructions that you don't quite understand, what it means is that these instructions are not for you;  don't try to follow them, you are going to wreck things.  Ignore this post, move on.

1. Using regedit go to HKLM\SYSTEM\CurrentControlSet\services\gpsvc and:
1. Change the owner to yourself.
2. Grant Administrators (not just you) full control.
3. Change the value of “Start” from “2” to “4”.
2. Now go to HKLM\SYSTEM\CurrentControlSet\Control\Winlogon\Notifications\Components\GPClient and:
1. Change the owner to yourself.
2. Grant Administrators (not just you) full control.
3. Delete the entire key. (Possibly after exporting it so as to have a backup.)
3. Restart your machine.

My notes on "Greg Young - The Long Sad History of Microservices"

Greg Young - The Long Sad History of Microservices
From the "Build Stuff" event of April 2017.

Talk begins at 9:45.

Highlights of the talk:

27:00 Placing a network between modules simply to enforce programmer discipline 

29:05 There is other levels of isolation I can go to. I can run a docker container per service. That's the coolest stuff right? What that means is I can make it work on my machine so I send my machine to production. 

29:52 Now, one thing that's very useful is I don't necessarily want to make this decision up front. And I don't necessarily want to make the same decision in dev as in production. I may want in dev to have a different way that we run things, why? because bringing up 19 docker containers on your laptop is not very much fun. I may prefer to host everything inside a single process to make debugging and such a lot easier when I am running on dev in my laptop. Whereas in production we may go off to multiple nodes. 

34:16 If you have maintenance windows, why are you working towards getting rid of your maintenance windows? Is this a business drive or is this you just being like C.V. driven development? 

My notes:

Unfortunately his shrieky voice makes him sound like he is bitching about things, which in a sense he is, but it would help his cause to deliver his criticism in a more palatable tone. Also, in order to make his point about microservices being nothing new he seems to disregard statelessness.
