OverEncrypt - paranoid HTTPS
View OverEncrypt.md

OverEncrypt

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.

WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.

I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.

The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

Theming Slack for OSX

So, you love Slack, but you hate applications with large white backgrounds? Why not use Dark Mode!

Unfortunately, Slack does not have a Dark Mode, although it's on their list of possibilities.

But, don't fret - there is a solution! Because the slack native desktop apps are just wrappers around a web app, we can inject our own CSS to customize the application to our liking.

You are trying to make a lot of simulataneous network connections to localhost. You get up to about 2000 HTTP requests per second, when your CPU usage goes up to 100% on all cores.

Behind Closed Doors: Managing Passwords in a Dangerous World

Description

A modern application has a lot of passwords and keys floating around. Encryptions keys, database passwords, and API credentials; often typed in to text files and forgotten. Fortunately a new wave of tools are emerging to help manage, update, and audit these secrets. Come learn how to avoid being the next TechCrunch headline.

Abstract

Secrets come in many forms, passwords, keys, tokens. All crucial for the operation of an application, but each dangerous in its own way. In the past, many of us have pasted those secrets in to a text file and moved on, but in a world of config automation and ephemeral microservices these patterns are leaving our data at greater risk than ever before.

About Those Lava Lamps
View about_those_lava_lamps.md

Around 2006-2007, it was a bit of a fashion to hook lava lamps up to the build server. Normally, the green lava lamp would be on, but if the build failed, it would turn off and the red lava lamp would turn on.

By coincidence, I've actually met, about that time, (probably) the first person to hook up a lava lamp to a build server. It was Alberto Savoia, who'd founded a testing tools company (that did some very interesting things around generative testing that have basically never been noticed). Alberto had noticed that people did not react with any urgency when the build broke. They'd check in broken code and go off to something else, only reacting to the breakage they'd caused when some other programmer pulled the change and had problems.

Himawari-8 animation tutorial

Here’s how to make animations like this one. It requires intermediate Unix command-line knowledge, to install some tools and to debug if they don’t work. You’ll need these utilities:

  • curl (or you can translate to wget)
  • convert and montage, part of ImageMagick
  • ffmpeg, plus whatever codecs
  • parallel, for iteration that’s nicer than shell for loops or xargs
  • run everything in zsh for leading 0s in numerical ranges to work

Diversity needs resources.

ideas are great. here are some great ideas. you however cannot implement ideas without resources, which basically means money. I am a lot less interested in ideas for a company right now that aren't backed by that company's money / staff.

a few ways to use resources:

  • do you have 2 awesome recruiters who want to do more? let them do it full time.
  • sponsor your employees to give talks about things they care about. (mentorship? good management? =D)
  • systematically reward people for doing diversity work. give them promotions or raises. let everyone know that's how it works.
  • sponsor events (like AlterConf) in your office, and give them organizational support.
You can’t perform that action at this time.
