a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

TL;DR

When you are in a shell in Linux, you may be led to believe you are in directory xyz but might actually be in directory pqr.

Demonstration

In a terminal,

These settings should be changed to prevent Firefox for Android from releasing tabs
browser.tabs.expireTime = seconds; 0 is never
toolkit.browser.contentViewExpire = seconds; 0 is never

:multi-process:
browser.tabs.remote.autostart true,false
browser.tabs.remote.force-enable true,false
dom.ipc.processCount 1...any

ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable. I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (HTTPS Everywhere No longer required: Enable HTTPS-Only Mode, NoScript/Request Policy, uBlock origin, agent spoofing, Privacy Badger etc), and all plugins set to "Ask To Activate".

"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation

I believe the following is the best way to work with Nagle's algorithm / TCP_NODELAY / TCP_CORK.

It is described in this RedHat manual and the verdict is:

• Set TCP_NODELAY = 1, always.
• If you can batch data for sending by creating a buffer manually, or using writev(), prefer that.
• If you cannot (e.g. "when using different libraries that provides abstractions for layers" from the above manual):
  • Set TCP_CORK = 1, then write the data, then set TCP_CORK = 0.
• This builds a packet in kernel space and then flushes it out.

// .stglobalignore

// These prevent SyncThing from trying to sync data that's locked, constantly changing, going to be thrown out, unimportant, etc.
// Lots of conflicts/issues disappeared using these ignores, but do check to prevent major disappointment!
// *.log and *cache* are in there, just so you know.. but firefox' startupCache and offlineCache will be synced.
// Ignores are case sensitive.
// Put both .stignore and this .stglobalignore in the root of your sync folder(s) (where .stfolder resides)
