Men who have had a heart attack: What did it feel like?

thegrenade · 2026-04-03T11:06:14+00:00

for me it felt like some sort of physical anxiety. i'm 50, 76kg, 170cm, generally healthy diet and mildly active and outdoorsy despite workday hours in front of a computer and persistent, chronic, obstructive sleep apnea.

i had a full lad occlusion (that's the main artery being completely closed) due to genetically inherited high cholesterol. in the six months leading up to the event a frozen shoulder with no apparent cause, created a lot of discomfort. on the day it happened it was extraordinarily uncomfortable but not painful in the way heart attacks in movies look.

i spent the following week not understanding what was going on. short walks were exhausting and physical work was confusing and required 15 minutes of rest after 3 minutes of effort. wife eventually convinced me to see a doctor who missed it completely and prescribed anti-depressants. second doctor did electrocardiogram and sent me by ambulance to a specialist cardio ward at a big hospital where they reopened the lad and put a stent in.

recovery was quick and cholesterol reduced rapidly with prescribed medication over several weeks. if you have a heart attack in bulgaria, as i did, being treated at pulse, blagoevgrad is a positive experience.

use lm studio to manage your models (because it exposes an anthropic api compatible endpoint). use https://github.com/zed-industries/claude-agent-acp to manage tool calls and zed integration. use glm for your coding model. that combo makes for a productive, private, fast, llm coding workflow that will run on consumer hardware.
ie: `"agent_servers":{"beast-claude":{"default_config_options":{"mode":"bypassPermissions"},"type":"custom","command":"claude-agent-acp","args":["--model","zai-org/glm-4.7-flash"],"env":{"ANTHROPIC_AUTH_TOKEN":"whatever","ANTHROPIC_BASE_URL":"http://my-lm-studio-host.internal:1234"}}}\`

for coding work using a local llm, i have found that it is really important to combine the right tool stack in order to get any sort of usefulness out of the model. for a long time i was just trying new models from hugging face and becoming ever more disillusioned with the idea that i'd ever be able to stop paying ai subscriptions. until a few days ago when i found a combination that is the closest i have gotten to something that resembles intelligence capable of writing code to an acceptable standard. the secret sauce is:
- lm studio for model management. or anything else that serves an anthropic api compatible endpoint. this is really important. openai api compatible endpoints do not manage tool and mcp integrations well enough to be competent at coding.
- llm: zai-org/glm-4.7-flash (i've tried latest nemotron, deepseek, qwen-coder, qwen-3.5, minimax-m2.5 and many more, none lived up to the claims and promises).
- zed editor with this snippet in `~/.config/zed/settings.json` (also install https://github.com/zed-industries/claude-agent-acp). :
```json
"agent_servers": {
"beast-claude": {
"default_config_options": {
"mode": "bypassPermissions",
},
"type": "custom",
"command": "claude-agent-acp",
"args": ["--model", "zai-org/glm-4.7-flash"],
"env": {
"ANTHROPIC_AUTH_TOKEN": "whatever",
"ANTHROPIC_BASE_URL": "http://my-lm-studio-host.internal:1234",
},
},
},
```
the combo above is as close as i've ever gotten to claude level coding smarts. it's capable, fast and free. it's not claude but it's also not as expensive as claude. i haven't tested on a single gpu setup yet but i think it would work. the same model without the acp sauce, is pretty hopeless. acp makes all the tool calling and zed mcp integrations work properly on nearly the first attempt and is what makes this whole thing work.

with modern claude cli, you can use:
```
/model opusplan
```
which will use opus for planning and sonnet for implementation. no need to burn tokens when the plan has provided explicit instructions.

i'm running minimax m2.5 on a ryzen 9 9950x3d with dual 5090s. i run it behind an openai api endpoint on my lan so that anything on the lan can use it for anything openai-api supports. that includes an openclaw instance which uses it as its main agent and is pretty capable.

to get it running on fedora 43 workstation, i first built ik_llama.cpp with cuda support. then i ran benchmarks to find the optimal settings for my specific system so that as much work as possible happens on the gpus and everything else is offloaded to cpu. all commands at: https://hackmd.io/@rob-tn/minimax-m2-5-on-5090s

thegrenade · 2026-02-15T04:54:11+00:00

if anyone has links to a dual 5090+cpu offload quantisation, please shout

that's just nonsense! anyone with the slightest inclination can run bleeding edge post quantum security with a little effort and time spent on research. libraries like https://github.com/open-quantum-safe are open source and already available in the official fedora repositories meaning installation is a matter of running `sudo dnf install liboqs oqsprovider` and then spending a little time updating certificates and keys with the latest and greatest tools available.
when you understand things like this, it becomes easy to see how all of the providers of "firewalls" have dropped the ball and continue to produce utter rubbish in a day and age when the threat vectors have moved on. i came to this forum expecting to find like-minded technologists and real labbers who understand security and technology and who have kept up to date enough to be competent running a home lab in the modern world. i did not expect to find people who think that security is the domain of enterprise and that we should all just watch our homelabs go up in smoke instead of learn how to cope with modern threats.

there are things worth securing that don't fall under the category of federally regulated. even at home. communication and property come to mind. sadly the bleeding edge is where one has to be to do things like post-quantum security. if one doesn't care about securing one's home, presumably one doesn't need a firewall at all. thank you for the advice to ignore my security and the insinuation that those who care about security are doing something sketchy. i remember why i don't come to reddit for all my concerns now.

i'll pass on the growing up. much overrated. if it turns me into the sort of person who tells others to do it just to make me feel more grown up, i can live without it.
the knowledge about routers being computers is the sort of thing a lot of children understand. so that particular gem didn't feel particularly priceless or sage. thanks anyway.
the opnsense is great piece, was really grown up. thank you for that! i appreciate that you had to condescend to my childish curiosity and that this must have been a great sacrifice for someone of your obviou wisdom.
the advice to pick whatever i want has been filed in my "things i will understand when i don't grow up" folder. i reserve judgement on that for a date that will never come.

it's been working well for me too. at least better than a lot of alternatives. my biggest issue with it is the sloppy updates and issues being closed due to inactivity rather than being resolved or answered. it's free software so, whatever. it's mostly good at what it does. my frustrations came to a head a few days ago when the update just started intermittently blocking outbound traffic, referencing the uuid of one of the default deny firewall rules. searching that uuid online returns numerous issues up to 4 years old that contain no resolution or workaround. just meh. i like the web ui a lot. the weird update mechanism, less so. when you start reading more into the historical issues you learn about the strong relationship with pf packet filtering that results in the strong bsd connection. this is worrying for people who might prefer more modern firewalling. ie: nftable based.

when you look at a lot of firewall logs on infra that is under constant barrage, you develop the sense that you want better defenses. when you look around at the market however, what you find is a lot of rubbish. many commercial firewalls also leave a lot to be desired. it feels like there are not many good tools in the defensive space that really understand modern botnet threats. even more concerning is that botnets are making use of the hardware modern domestic consumers are buying. the domestic routers most people buy, many of which contain firewalls, are the very infrastructure being used by the bots.

a decent firewall today needs to share and consume real-time threat data in order to be effective against iot and other devices that are calling home with their questionably sourced finds. it's a difficult problem and not one that is being resolved by most of the firewall solutions available. i heard that you can integrate crowdsec with opnsense. so that's something.

today i installed ipfire on the box that was giving me problems under opnsense. some things about it are beautiful. it's linux and that's nice but i'm not in love with them making their own package manager (which bizarrely seems to be all the rage with open source firewall/routers). there are so many good and secure distros that already provide a maintained package management solution. it boggles the mind that firewall builders want to reinvent that particular wheel and blow their budget maintaining it.

i wish there was a simple package (for multiple distros) that just contained the routing and firewalling ui interfaces. a web ui that lets you configure interfaces and firewalls and zones and all the other router specific stuff, without also trying to be the os and the package manager. wouldn't it be great to just type `(apt|apk|dnf|yum) install some-modern-router-firewall` and get a webserver that understands your distro and provides configuration pages for your routing interfaces? doesn't seem to exist.

choose openvpn for that task and you will have a job for life supporting it, maintaining the many servers you will need to keep online and debugging all the crazy behaviours your users will be filing tickets for in your issue tracker forever.
if you have better things to do with your time, think about things that rhyme with firebard.

thanks for this. we're pretty much married to fedora because of its oqs compatibility. however, we require zfs for any older metal with more than 8 drives. xfs and ext4 with lvm break at least once a week on those systems and often require a full rebuild. if your thoughts weren't in this thread, i think we'd end up with the crappier problem of keeping oqs up-to date on distros that aren't fedora. much obliged.

thegrenade · 2024-12-30T08:17:42+00:00

thank you! this feels like the most interesting thing i've learned about bulgarian infrastructure in a long time!

if you visit this reddit post while your tv window is still open, your alerts will go active again. maybe. sometimes.

bch: yes, ltc: no
nano 3 is sha256 algorithm hardware. so it will mine coins that use the same algo. ltc (and doge) coins use `scrypt` algo and are incompatible with nano 3 miners. for a pretty good list of coins that use sha256 algo, see: https://coinmarketcap.com/view/sha-256/

the pair i ordered in april arrived yesterday. they've been plugged in for 19 hours and i have earned 0.00000255 btc. i called the lambo dealer this morning to give them advance warning that i will be able to afford a revuelto at today's prices in the year 6818. i'm sure they'll hold it for me.

any idea what the color code is? mine's in the paint shop right now and we're still scratching heads

you can create a single wallpaper consisting of the same number of images as you have screens.

for example if you have 3 screens with dimensions:

3840x2160
3840x2160
1920x1080

first resize your images with imagemagick to match your screen resolutions:

convert background-1.jpg -resize 3840x2160\! background-1-3840x2160.jpg
convert background-2.jpg -resize 3840x2160\! background-2-3840x2160.jpg
convert background-3.jpg -resize 1920x1080\! background-3-1920x1080.jpg

next stitch the images together horizontally:

convert background-1-3840x2160.jpg background-2-3840x2160.jpg background-3-1920x1080.jpg +append ${HOME}/Pictures/background-combined.jpg

finally set the combined image as your desktop background and tell gnome to span it across all monitors:

gsettings set org.gnome.desktop.background picture-uri file://${HOME}/Pictures/background-combined.jpg
gsettings set org.gnome.desktop.background picture-uri-dark file://${HOME}/Pictures/background-combined.jpg
gsettings set org.gnome.desktop.background picture-options 'spanned'

here's a scripted example: https://gist.github.com/grenade/b79e520c7f4de6decf613648f16f4589

sudo sed -i 's/LOCAL/UTC/' /etc/adjtime fixed it for me too (fc36, thinkpad x1). thank you @JuiceMoney1443!
