  • You Don't Know JS » Mar 8, 2015

    Things learned today:

    • Word of the day - mulct : to punish by fine.
      • Ex: The ruler used an income tax primarily to mulct his subjects.
    • How to keep a cuff in jeans.
    • Bash command line practice from Coursera - Part 1 and part 2.
    • You don’t know JS - This and Object Prototypes
      • Many programmers don’t fully understand how to use this and fall back to reliance on lexical scope instead. 

    function foo(num) {
    console.log( "foo: " + num );

    // keep track of how many times `foo` is called
    data.count++;
}

var data = {
    count: 0
};
    • An alternative is to use this.count++; and to call the function via foo.call( foo, i );, which forces this to point at the function object.

  • More Unix and CSS » Mar 6, 2015

    Things learned today:

    • Bash guide from startup engineering on Coursera
    • The typical place to store custom bash scripts is usr/local/bin.
    • chmod 755 to reserve write access for the user and make executable.
    • Script created: zippy (to unzip/extract anything).
    • Auto-complete sudo and man, colorize ls and grep.
    • Benefit of using tmux (or screen) - terminal sessions become persistent until you shut down.
    • Karen in Californication - “They’re just words - I know you mean them, but I don’t know what they mean to you.”
    • Flexbox documentation - supposed to make aligning stuff easier.
    • Clearfix for positioning stubborn divs.
    • Percentage heights are tricky to use in CSS. Vertically aligning content can also be difficult.
    • jQuery Mobile makes working with layout very difficult. Alternative flipswitches here.
    • Setting and getting cookies with javascript. *Made something to help my parents pick somewhere to eat for dinner.

  • Powershell and Unix Tips » Mar 2, 2015

    Things learned today:

    • More on Powershell from Microsoft’s training course:
      • You can use Powershell for remote servers on mobile devices using Powershell Web Application.
      • The reason that you need .\ScriptName to run a script within a directory is to prevent attacks. In the old days of Unix, attackers would create scripts such as “pwd” that would execute when run within a directory.
      • The Powershell community is very strong and helpful. Try asking questions on Powershell.org or on Twitter (#PowerShell).
      • Implicit remoting allows you to run cmdlets on different servers all locally.
      • Using icm with sessions allows you to issue commands to many computers at once remotely.
    • Contract templates for freelancing.
    • From Unix tutorial:
      • Command substitution allows you to run a command and store the output to a variable or use it as an argument. Syntax: $(command)
      • Process substitution allows a command to appear as a file. Syntax: <(command)
      • Piping to grep allows you to quickly find a certain word or phrase in a file.
      • Awk and sed are good for simple parsing or text manipulation problems. The author only uses sed to replace text or delete lines.

  • Word Realms » Feb 26, 2015

    Things learned today:

    • Ben Schwartz would be well cast as the judge in Blood Meridian.
    • Playing Word Realms today, here are some thoughts:
      • The graphical style does not seem polished enough for a standalone game.
      • There is not enough guidance to continue to adventure in old zones once the quest marker tells you to move on, yet this is almost essential to gear up enough to progress.
      • The phrases that your character says while attacking is a highlight of the game for me.
      • The main ending is pretty messed up. There’s one viable trinket for warriors, crafting feels underdeveloped.
    • Redis is:
      • A key-value cache and store.
      • A data structure server.
      • One type of NoSQL database.
      • Better than MongoDB for software where performance is important and you already know how you want to query your data.
    • MongoDB training available here.
