Setting up additional entropy for your Ubuntu VPS with haveged

June 28, 2020

We've recently ran into an issue with one of our staging servers where a scheduled cron job would occassionally hang for a few minutes before executing.  The issue turned out to be due to a low entopy (i.e. randomness) value in /proc/sys/kernel/random/entropy_avail.

Randomness in Linux is generated from hardware interrupts such as the keyboard, mouse, and disk/network IO.  This goes into a pool which then gets consumed by applications that require randomness for security, such as …

Lockdowns

March 29, 2020

I'm currently stuck in Athens, Greece and will probably ride things out here as most of the world is currently on lockdown.

  • you need a quiet area to …

Renewing a US Passport in Kuala Lumpur, Malaysia

I've recently renewed my US passport while traveling in Kuala Lumpur, Malaysia. I actually still had about 10 months left before expiration but I decided to renew it earlier as some countries require at least 6 months validity before they let you in. I didn't want to wait until the last minute.

Since Malaysia allows for up to a 90-day stay for tourists from the US, I figured this would be a good place to …
