Building Erlang R23.0 on Debian/Ubuntu

Filed under: Computing,Science & Tech — Tags: , , , , , , , — zxq9 @ 20:35

As an update to my previous notes on building R22.2, my current notes for building Erlang R23.0 and installing ZX using kerl on a fresh system (Kubuntu 18.04 LTS) are below. The same instructions (or very nearly the same) should work for any Debian or Ubuntu version within a few years of 18.04 LTS.

sudo apt update
sudo apt upgrade
sudo apt install \
    gcc curl g++ dpkg-dev build-essential automake autoconf \
    libncurses5-dev libssl-dev flex xsltproc libwxgtk3.0-dev \
    wget vim git
mkdir vcs bin
cd vcs
git clone https://github.com/kerl/kerl.git
cd ..
ln -s ~/vcs/kerl/kerl bin/kerl
kerl update releases
kerl build 23.0 23.0
kerl install 23.0 ~/.erts/23.0
echo '. "$HOME"/.erts/23.0/activate' >> .bashrc
. ~/.erts/23.0/activate
wget -q https://zxq9.com/projects/zomp/get_zx && bash get_zx

[NOTE: ~/vcs/ is where I usually put “version control system” managed code and my backup and sync scripts know to never copy or update that one.]

And that’s that. If you’re on a full desktop installation some of the packages in the apt install [stuff...] may be redundant, of course (who doesn’t already have wget and git?), but that’s no big deal.

Day 30, Summary Data

Filed under: Fast Food Fighter — Tags: , — zxq9 @ 20:28

Unfortunately the digital data for days 28 through 30 was lost before I could write the final three days of posts. All data on hardcopy (food receipts, nutrition information and the final medical testing information) still exists and whatever was able to be scannable I have posted below. I’ll eventually format this into a table, but for now the images will have to do!

The results of my blood tests at day 0, day 15, day 30 and day 45 (15 days after returning to a normal diet) are posted below. McDonald’s did not have any significant effect on my blood levels, though working out at such a high intensity across the month certainly had some impact, though nothing unexpected according to the doctors.

The killer finding turned out to have nothing to do with health and everything to do with cost. McDonald’s is expensive! It cost me about $750 to eat at McDonald’s for one month — and I’m just one person! This explodes the myth that “poor people are fat because they have to eat at McDonald’s”. It appears more like that poor people who eat at McDonald’s are poor because they throw their money at nonsense luxuries like McDonald’s instead of saving it and cooking at home!

Blood work from 2009-05-09
Blood work from 2009-05-23
Blood work from 2009-06-09
Blood work from 2009-06-23
Vitals (body composition, etc.) scans from 2009-05-09 and 2009-05-23
Caloric intake and cost per day throughout the month.
~$750 for one person for one month! AH!

Day 29, More digital terror!

Filed under: Fast Food Fighter — Tags: , — zxq9 @ 20:17

Unfortunately the digital data for days 28 through 30 was lost before I could write the final three days of posts. All data on hardcopy (food receipts, nutrition information and the final medical testing information) still exists, so I can still present at least the performance data, but unless I can recover the workout bits I won’t be able to catalogue exactly what I did on these last three days in terms of workout.

This is a placeholder page just in case I am able to recover the data at some point.
