sloanlance / pseudorandom_alphabetical_string.js

JS: pseudorandom alphabetical string
// "Pseudorandom", because it's not guaranteed to be truly random.
// Express a floating point random number as base 26 and remove "0." from the beginning.
// Next, to make it alphabetical, replace digits 0-9 with letters q-z.
// @returns {string} Usually 10 to 13 characters in length
Math.random().toString(26).substring(2).replace(/[0-9]/g, function (c) {return 'qrstuvwxyz'[c]});
// Alternate, non-function versions (which is more efficient?)
Math.random().toString(26).substring(2).split('').map(c => 'qrstuvwxyz'[c] || c).join(''); // split to array, replace, join to string
Math.random().toString(26).substring(2).replace(/[0-9]/g, c => 'qrstuvwxyz'[c]); // examine only characters 0-9
Math.random().toString(26).substring(2).replace(/./g, c => 'qrstuvwxyz'[c] || c); // examine all characters

How to make a standalone iOS app with Pythonista

After you made some cool games or apps with Pythonista, you may want to make it run as a standaone app on iPad/iPhone and possibly share it on the AppStore. This how-to tells you how to do it.

What you need:

  1. Pythonista code you wrote
  2. A Mac with Xcode 7.1 installed
  3. iPhone/iPad running iOS 9

Steps:

  1. Download PythonistaProjectTemplate.zip. The original PythonistaProjectTemplate described at http://olemoritz.net/pythonista-15-whats-new-and-whats-missing.html does not work with Xcode 7. I updated it to work with Xcode 7 and added a more interesting example than the plain old Hello World thing.
  2. Unzip the file and open the project in Xcode 7.1. In project settings, change the Bundle Identifier from com.yuhangwang.pythonistaproject to something else.

sloanlance / getTimestampWithFraction.php
Created January 15, 2018 20:30
PHP: A replacement for the shamefully broken DateTime::getTimestamp
/**
* Problem: `DateTime::getTimestamp` returns **_`int`_**! Calculations such as the following
* are incorrect if the `DateTime` object includes fractions of seconds:
*
* ```php
* $durationSeconds = strval($endTime->getTimestamp() - $startTimestamp);
* ```
*
* `DateTime::diff` can subtract properly, but only under PHP 7.1. (Curiously,
* `DateTime::getTimestamp` still returns `int` under PHP 7.1!)

sloanlance / Karabiner: Require fn for esc
Last active December 21, 2017 17:10
Karabiner: Require fn modifier key to activate esc key. Useful for preventing accidental esc keypresses on Macs with a Touch Bar. Doesn't affect all other modifier combinations (i.e., option + command + esc works without requiring fn, too).
Please see the README.md file in this gist.

MediaWiki: CSS to make page tables of contents float on the right.

/* Simple CSS change to make page tables of contents float on the right of the page,
letting content wrap around it. To give a little separation from the content,
a wide white border is used instead of a transparent margin. The border color may
need to be changed to look good with other MediaWiki skins. */

jq: Depersonalize JSON – http://bit.ly/Depersonalize_JSON

Depersonalize JSON

Why

If JSON data is to be shared for analysis, it's often necessary to depersonalize the data first. Depersonalization is different than anonymization. If data is anonymized, all information about the user is removed. Depersonalization, however, changes the user information to values that can't be recognized as being related to the real user. This way, it's still possible to see relationships within the data.
