Megadosing B6 can lead to B6 toxicity/syndrome as a result of its longer half life and ability to accumulate in the system. Between multivitamins, energy drinks, preworkouts and food, it's very easy to go well above the recommended amount. I'm currently recovering from B6 induced peripheral neuropathy (tingling in my feet) caused by 20-50mg/day over several years.
Back around 2000, I was writing software patches for a large telecom company. These patches had to be applied to live, inservice telephone switches and equipment that were powering public phone services - restarts and downtimes were not an option. Needless to say, careful consideration had to be given with regard to how a patch was developed and applied.
I don't recall the specifics, but one fateful patch had a very large compound boolean expression that included an invalid condition. For whatever reason, that expression didn't or couldn't receive 100% test coverage.
When applied, this patch took down the entire phone service (including emergency 911) for the island of Newfoundland Canada and all its residents (maybe 300-500k people).
The immediate fix was simply a new patch that reverted the bad patch. Unfortunately, it took several hours from the point we learned of the issue to writing, delivering and applying the fix.
I've heard that Newfoundlanders have a reputation for being very friendly, so I like to believe that all has been forgiven and forgotten and that I may one day visit the island in peace.
I discovered PostgreSQL in a similar happenstance sort of way - working at a large telecom directly out of college in the late 90s, tasked with setting up a MySQL backed webapp to manage some internal processes. Fortunately, I was unable to compile MySQL on our HPUX workstations (issue with threads IIRC), PostgreSQL to the rescue. Been using it ever since.
We're currently using Crystal 0.25.1 with the Kemal web framework to provide an online paycheck calculator for US based employees (it's basically a demo/tool for our SaaS based accounting, payroll and fund raising app).
Really impressed with the language so far and hope to expand its use within our organization.
We use FreeBSD in production (SaaS accounting/payroll app) as a load balancing proxy/web server (Nginx) and outgoing mail server (OpenSMTPD) because it's a stable, proven OS with sane defaults. Thanks to OpenBSD, we get an awesome firewall (PF) and dead simple OpenSMTPD mail server (total config is around 25 lines which gives us DKIM signing and PKI with no additional software).
At home, FreeBSD is used as a HTPC (Kodi), file server and backup box (it acts like a Time Machine for our Macs via netatalk and for Linux we use rsnapshot over NFS).
I use Linux and a window manager with 10 virtual desktops/workspaces, keyboard shortcuts let me instantly jump to or scroll through them.
That said, I've never understood the need for multiple physical monitors. Maybe someone can explain a few advantages of using more than 1 monitor vs a single with multiple workspaces?
