Is Postgres fast enough for job processing these days? We do hundreds of millions of jobs now and even years ago when our volume was a fraction of that, we got a huge performance boost moving from Postgres + Que to Redis + Sidekiq. Has that changed in the intervening years?

Hundreds of millions over what time frame? I got a system with Rails/Solid Queue + Postgres and doing about 20M jobs/day on a $45/mo VM with plenty of room to spare.

On some of my cover letters I wrote "full stack from the transistors upwards", because at one point or another I have shipped code in:

- IC design software (at a startup bought by Cadence)

- an IC (contract out of Dallas semi)

- FPGA HFT acceleration

- fixing some OS drivers for Windows CE

- finding a compiler bug

- various bits of embedded firmware in C and assembly for various platforms

- debugging with a scope

- desktop applications

- a web server (defunct ZWS)

- web apps (Perl. Long time ago)

Somehow I've never written a react app.

True for coffee as well (if you substitute psychedelic with a more appropriate word).

Yep, thats a good one. Caffeine is deadly to insects, but a mostly safe stimulant for us. Nicotine also comes to mind. Plants have developed tons of defense mechanisms that are deadly to one class of animals, but useful or only mildly deterrent to others. Avians are immune to capsaicin, but an irritant for mammals.. except for some hairless primates.

So, about one mushroom species in five is poisonous. Why is the ratio so low, why are there lots of edible ones? Without hard-shelled seeds to spread, why be eaten? And the poisonous ones apparently don't use color as a warning signal, and don't smell all that bad, and some of the poisons have really mild effects, like "gives only some people diarrhea" or "makes a hangover worse". Meanwhile three of the deadliest species seemed to need their toxin (amanitin) so much that they picked it up through horizontal gene transfer. Why did just those ones need to be deadly? In addition to which we have these species that don't even make you sick, just make you trip out, a function which looks to have evolved three times over in different ways. What kind of half-assed evolutionary strategies are these? What do mushrooms want?
choilive · 2 months ago
Its the same evolutionary patterns that plants went through.

Most mushrooms are edible because their spores can pass through the digestive system of most animals, thus allowing them to spread.

Other mushrooms developed toxins to protect their fruiting bodies - often the biggest threat isn't larger animals, but insects. Toxins that are neurotoxic to insect nervous systems, happen to cause mostly "harmless" psychedelic trips to our brains. Other toxin mechanisms happen to be deadly to both insects and humans.

As proof of this evolutionary arms race, there are fruit flies that have developed resistance to amatoxins.

>it is "known" at least as much as any other protocol.

No. It is not. Please understand what the LLM's are doing. Claude nor ChatGPT nor any major model knows what MCP is.

They know how to function & tool call. They have zero trained data on MCP.

That is a factual statement, not an opinion.

choilive · 3 months ago
That is an easily falsifiable statement. If I ask ChatGPT or Claude what MCP is Model Context Protocol comes up, and furthermore it can clearly explain what MCP does. That seems unlikely to be a coincidental hallucination.

You may be right, but historically speaking, "this company will stick to quality standards" is a bad bet compared to "this company will cut corners to squeeze out more profit".
choilive · 3 months ago
I think the apt comparison is the rental car business. They are reasonably good at quality standards because the competition is stiff, and if the vehicles aren't reliable and clean, you will just use the company next door. This incentivizes prudent fleet management, and thanks to economies of scale, having in-house mechanics to constantly maintain the fleet quickly becomes cost efficient.
choilive commented on What happened to Transmeta, the last big dotcom IPO   dfarq.homeip.net/what-hap... · Posted by u/onename
btilly · 3 months ago
I don't either. Even with their problems, they didn't miss by much.

One key factor against them, though, is that they were facing a company whose long-term CEO had written Only The Paranoid Survive. At that point he had moved from being the CEO to the chairman of the board. But Intel had paranoia about possible existential threats baked into its DNA.

There is no question that Intel recognized Transmeta as a potential existential threat, and aggressively went after the very low-power market that Transmeta was targeting. Intel quickly created SpeedStep, allowing power consumption to dynamically scale when not under peak demand. This improved battery life on laptops using the Pentium III, without sacrificing peak performance. They went on to produce low power chips like the Pentium M that did even better on power.

Granted, Intel never managed to match the low power that Transmeta had. But they managed to limit Transmeta enough to cut off their air supply - they couldn't generate the revenue needed to invest enough to iterate as quickly as they needed to. This isn't just a story of Transmeta stumbling. This is also a story of Intel recognizing and heading off a potential threat.

I always found it ironic that Intel benignly neglected the mobile CPU/SoC market and also lost their process lead despite this supposed culture of never underestimating the competition. The paranoid Intel of the 80s/90s is clearly not the one that existed going into the 2000s and 2010's

PiKVM seems to be the large competitor here and is completely open source. If you're looking into KVM solutions, probably check it out, but JetKVM is over 50% less, which is a huge argument in favor of it.

I can buy 3 or 4 x JetKVMs for 1 PiKVM, pretty hard to justify going for PiKVM unless there is a PiKVM feature you need
