Notes

17:28 past the bridges and into software engineering

Software Engineering is all design. Production used to be printing the CDs, and nowadays it is hitting the "deploy" button.

"scaling the costs to the consequences" -- the point is not to minimize the cost, the point is to scale it to the consequences. Risks must be taken, and if the potential gains are huge, then the risks can be correspondingly large.

GOTO 2014 - REST: I don't Think it Means What You Think it Does - Stefan Tilkov

My notes on GOTO 2014 - REST: I don't Think it Means What You Think it Does - Stefan Tilkov

"People decide they want to build something in a RESTful fashion, so they spend all their time arguing about where the slashes go".

"It is the first litmus test for your REST API whether you depend on specific characters in your URIs for things to work."

(From the client's point of view.)

GΟΤΟ 2014 - Microservices - Martin Fowler

My notes on GΟΤΟ 2014 - Microservices - Martin Fowler

Characteristics of Microservices

  1. Componentization

  2. Organized around business capabilities

  3. Products not Projects

  4. Smart endpoints and dumb pipes

  5. Decentralized Governance

  6. Decentralized Data Management

  7. Infrastructure Automation

  8. Design for failure

  9. Evolutionary Design

With services we typically use some kind of interprocess communication facilities such as web service calls or messaging or something of that kind.

How big should a microservice be?

"It should have one responsibility" --too vague

"Andy" android emulator - Avoid it like the plague

If you were thinking of installing the "Andy" android emulator on your PC, think again. Here is my experience with it:

  1. The installable file (Andy_46.2_207_x64bit.exe) is a whole 431 MB.
  2. It installed VMware without asking me, so the installation took a really long time.
  3. It installed some "Bonjour Service" by Apple, Inc. without asking me.
  4. It replaced all my .apk icons with its own icon without asking me. (I am using apk shell extension and I much prefer it that way.)
  5. During installation, there were 15 attempts to call home by "Andy" and/or by other crapware that it installed. (I have a firewall, so I didn't let any of that happen.)
  6. At the end of the installation, it popped up a message box saying that the installation failed because it could not detect my internet connection, and that it requires internet access in order to install.
  7. Despite the failed installation message, "Andy" was found under "installed programs" so I uninstalled it.
  8. During uninstallation there were a couple of more attempts to call home.
  9. After uninstallation it left "Bonjour Service" installed, so I had to go find it and uninstall it too.
  10. After uninstallation it left an "Andy" folder on the root of my user folder, which I had to delete.

What a piece of crapware!

Solved: "something went wrong" trying to create new user account on Windows 10

So, while trying to create a new user account on my Windows 10 computer, I get this:

The solution:

  1. Start a command prompt as administrator.

  2. Type the following command:

    net user <username> <password> /add

Voila, the user has been created.

What in fact went wrong is that Microsoft completely broke Windows after Windows 7.
