The CA/Browser Forum has voted to mandate that CAs must start checking CAA records to control certificate issuance (to verify what CAs are allowed to issue certificates for a domain) by September 8th, 2017.

Full language of the ballot is here.
I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6
apt-get update && apt-get install gdb

| * a GPIO pin connected to the external pulse source. | |
| * Once the pulse arrives, ESP32 wakes up from deep sleep and runs |
Using perf:
$ perf record -g binary
$ perf script | stackcollapse-perf.pl | rust-unmangle | flamegraph.pl > flame.svg
NOTE: See @GabrielMajeri's comments below about the
-goption.
Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:
Considerations to take when live streaming:
The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:
Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.
Set up the encoders as shown:
At the time of this writing, Rust and Cargo are available on FreeBSD/amd64 and FreeBSD/i386 only, whether it is from rustup or from the FreeBSD ports tree. Here is how I could bootstrap Rust and Cargo for FreeBSD/aarch64 from FreeBSD/amd64.
To be able to cross-compile anything, you need a userland for the target.
| A list of languages which compile to JS (Elm, Purescript, OCaml) | |
| (Inspired by this thread: https://groups.google.com/forum/#!topic/elm-discuss/Um7WIBTq9xU) | |
| They all support curry calling convention by default. | |
| Some interesting results: | |
| 1. `min` is curried function, only OCaml(BuckleScript) managed to optimize this overhead. | |
| 2. All optimize the self tail call | |
| 3. Only BuckleScript and PureScript type-specialized comparison functoin (>=) and inlined |
