I think most users have no clue how any of it works - there are so many footguns doing it yourself that probably an exchange like Coinbase is the best bet, but again, not your keys, not your coin...

I looked at crypto a little for a startup - the thing that isn't usually mentioned is the huge downside of custody. Not your keys, not your coin - and holding those keys securely, think fire, theft, hacks, backdoored hardware wallets,

This is basically technical debt of some sort - they may be minting so much money it doesn't matter atm, but eventually, someone will get some wins cutting costs. Probably just the bandwidth is a lot of it.

You're probably on the early part of the curve where anything works - small team, simple product, no scale - come back when one or two of these changes...

I think the flip side of this is at some point after looking at enough crap software, you feel free to write your own. You can actually solve your directly problems in simpler ways with a lot less code than more generic tools. I've had

True perhaps from a certain perspective, but k8s and the other orchestration technologies, etc. Also dev workflows in containers seem broken and hard - I think it offers a poor experience generally.

I never moved to containers and seeing the churn the community has went through with all of this complicated container tooling, I'm happy orchestrating small-scale systems with supervisord and saltstack-like chatops deployments - it&#x

You have to understand who you work for - most companies don't really care about their employees - they are means to an end and if they weren't absolutely needed, corps would do the work other ways. And Google is way past "Do

A config management and deployment system in the spirit of Saltstack and Ansible. Recently did some refactoring around a process-per-connection architecture in Python that ended up being fairly elegant.

Interesting, I built a whole rpc / file-server ala saltstack on top of something like this: https://github.com/mattbillenstein/salty Been using this on a couple startups for a couple years, but it lacks polish in

Yeah, just prefer writing little cli tools in Python or something once the shell script gets too complex... Sorta hate yaml drive config management and deployments sytems aka ansible, saltstack, etc; so ended up writing my own that's s

When they've kept my car, they've usually given me a ride or got me an uber home which was unexpected, but a nice touch.

Yeah, this is great and so easy to do with modern smart phones - Toyota sends a report with pictures which is pretty good too.

Do not underestimate the Musk reality distortion field... He's been saying FSD for like 10 years on investor calls and they just keep eating it up.

by mattbillenstein 2y ago
Wow, that is crazy. I've come to think of cars, and maybe other big purchases, as you're purchasing a culture; the company that made it and will service it - it's why Toyota is so highly regarded. I own a 20yo Toyota Tacoma -

Yeah, but you can always make this argument and build nothing - dealing with all the problems of every 3rd party SaaS / PaaS under the sun. Sometimes it's much easier to just build the thing and then you know where its' limit

Feels like I'm reading something I could have wrote - I did this some years ago at a startup and have been doing it ever since. I'm using single-character prefixes in most places and having typed ids is so nice to be able to immed

Yeah, Python has the array class too - well and numpy/torch/etc. Useful for numeric stuff, but you can't say have like a list of objects all contiguous very easily I don't believe.

The JIT will improve - you can also use PyPy to get speedups on programs that don't use a ton of C extensions. Also, free-threading is coming so we'll have threads soon. I don't know if Python can every really be fast as by d

Are you hosting this on residential internet? I think that's probably the main drawback. I host these types of things on a single vps - actually I have a few projects on one vps using different domains, so if you amortize the cost, it&

I've only done a few interviews the past couple years, but I've asked people to turn off coding assistants and not use an LLM on my coding screen. I want to know how _they_ think and solve problems, not how the LLM does. And gener

Yeah, but the SSDs today can write something like 2GB/s, so even if you're re-writing the entire OS, you should be able to do that in what? 1 minute max? Assuming they're using some fast parallel compression algo as well when

I know the Mac hardware is pretty trick, but man, I do most of my dev on Linux and have a Framework Laptop (AMD) running Ubuntu; it's just really nice for dev stuff to work the same way it does on our production environment... Also, th

VR has always sorta been a hedge against missing the next platform the way many companies missed out on the smart phone or social networking - it was never obvious it was going anywhere really.

I think Makefile is maybe the wrong analogy - the problem with most people and makefiles is they write so few of them, the general idea of what make does is at hand, but the muscle memory of how to do it from scratch is not. But, point take

I've built a few systems using msgpack-rpc - serves really well as a transport format in my experience!
