Pinellas County Running: 3.16 miles, 00:08:30 average pace, 00:26:52 duration
aiming for whatever felt easy. the humidity really was heavy with a light fog. woke up with no real pain and it was not until the end of the run where i felt a slightly sharp pain around my left glute and a bit in the left hip as well. thinking i need to reduce mileage a bit and try to train around it until i feel good enough to get back in to a routine again.

↳ In-reply-to » QOTD: What do you host on your home server? How do you host it? Are you using containers? VMs? Did you install any management interface or do you just SSH in? What OS does it run?

@mckinley@twtxt.net for me:

  • a wall mount 6U rack which has:
    • 1U patch panel
    • 1U switch
    • 2U UPS
    • 1U server, intel atom 4G ram, debian (used to be main. now just has prometheus)
  • a mini ryzon 16 core 64G ram, fedora (new main)
    • multiple docker services hosted.
  • synology nas with 4 2TB drives
  • turris omnia WRT router -> fiber uplink

network is a mix of wireguard, zerotier.

  • wireguard to my external vms hosted in various global regions.
    • this allows me ingress since my ISP has me behind CG-NAT
  • zerotier is more for devices for transparent vpn into my network

i use ssh and remote desktop to get in and about. typically via zerotier vpn. I have one of my VMs with ssh on a backup port for break glass to get back into the network if needed.

everything has ipv6 though my ISP does not provide it. I have to tunnel it in from my VMs.

Pinellas County - Long Run: 16.03 miles, 00:08:58 average pace, 02:23:34 duration
my ankle, achilles, and calves were fine walking but really tight the first 3 miles of the run (maybe the rope course?). kept it light for the first half then attempted MP or quicker. it was a little hard at times but comfortably discomfortable? all-in-all it was a good run.

Pinellas County - Long Run: 20.04 miles, 00:09:48 average pace, 03:16:16 duration
kept it chill with between 9:30 and 10:00. the first half almost felt too easy. it was not until i had to go over the overpasses again where my legs started to actually feel it a bit. the leg back i would just “rope” people in and then slow down for a bit to rest. this was a great confidence boost and a nice way to end the year.

Pinellas County - Long Run: 16.66 miles, 00:09:16 average pace, 02:34:24 duration
whew, rough plan was 3 miles warm-up, then 1 mile on/off at 8:30 pace, then cool down the rest of the way. little bit fast for some intervals, and boy did that bridge wipe me out (the third interval?). during the cool down had to stop to find tissues and also going up the final bridge. not trying to kill myself being i still have parental duties with it being christmas eve and all. overall it was a great outing if i must say so.

Today’s Advent of Code puzzle was rather easy (luckily), so I spent the day doing two other things:

  • Explore VGA a bit: How to draw pixels on DOS all by yourself without a library in graphics mode 12h?
  • Explose XMS a bit: How can I use more than 640 kB / 1 MB on DOS?

Both are … quite awkward. 😬 For VGA, I’ll stick to using the Borland Graphics Interface for now. Mode 13h is great, all pixels are directly addressable – but it’s only 320x200. Mode 12h (640 x 480 with 16 colors) is pretty horrible to use with all the planes and what not.

As per this spec, I’ve written a small XMS example that uses 32 MB of memory:

https://movq.de/v/9ed329b401/xms.c

It works, but it appears the only way to make use of this memory is to copy data back and forth between conventional memory and extended memory. I don’t know how useful that is going to be. 🤔 But at least I know how it works now.

Today I was fighting against a TOTP library in PHP, since it works for 6 and 8 digits, but for 10 it was giving inconsistent values, due to a conversion to a 32 bits int.

It felt amazing when, after a few hours, I found what was causing the error…

And found that many libraries have the same problem.
Now I get why TOTP is limited to 8 chars. It’s a 2FA but not a Password. Perhaps another algorithm will be needed to support 16 digits.

En un ejercicio de diseño, ¿que pasaría si hacemos el inicio de sesión solo con un código dinámico TOTP?

Lo que he encontrado es que muchos clientes limitan a 6 y máximo 8 o 10 caractères.
Quizás algo de 12 o 16 dígitos (similar a una tarjeta de crédito, por lo que describe frecuentemente), agregaría seguridad.

Aquí unas fórmulas interesantes para predecir la probabilidad de un ataque de fuerza bruta, dependiendo el número de dígitos.

↳ In-reply-to » Russia blowing up the Nova Kakhovka dam is an incomprehensible war crime. Among other things, it drains water from the Zaporizhzhia nuclear power plant, water that is needed for cooling. They are trying to generate a widespread disaster.

@prologic@twtxt.net I don’t agree. I think he’s a thug who benefits a lot if everybody thinks he’s a madman.

All through this war, there has been a repeated cycle:

  • We can’t give Ukraine weapon X; that will provoke Putin and he’ll drop a nuke!
  • Russian propagandists threaten they’re about to drop nukes
  • After lots of hand wringing, some country gives weapon X to Ukraine
  • No nukes are dropped

We’re on like the 5th iteration of this. Now it’s about F-16 fighter jets. In the meantime, a lot of Ukrainians AND Russians are dying en masse.
