pitched··on Show HN: Oblivus GPU Cloud – Affordable and scalable GPU servers from $0.29/hr
I found some charts here showing A100 roughly doubling a 3090: https://bizon-tech.com/blog/best-gpu-for-deep-learning-rtx-3...

With the 4090 being a fair amount more powerful, it might give the a100 a challenge for about 10% of the cost. That’s still about 10k hours of renting one with this service though.

pitched··on The Two Cultures (1959) [pdf]
> So the great edifice of modern physics goes up, and the majority of the cleverest people in the western world have about as much insight into it as their neolithic ancestors would have had.

This is a very nice way to try and explain Dilbert-style Pointy Haired Bosses.

pitched··on Ed Sheeran demonstrates how copyright is destroying musicians
Comparing against playing the song on radio (divided by how many listeners the station has), Spotify doesn’t look too bad.
pitched··on Are sockets the wave of the future? (1990)
I’ve wanted to get back on IRC for a while but don’t really know where people live in it these days. Are there any specific channels/servers that are still popular where I can start?
pitched··on PSVR2 hardware authentication has been cracked on PC
Atomic Heart had the best shader compile I’ve seen yet. It happened with a loading bar on the main menu and didn’t stop you from exploring settings. IMO the compile should be part of the install step outside the game though
pitched··on Google employees complain about CEO's pay raise as cost cuts hit company
The way biology evolves to adapt is also very shortsighted! Even without long-term planning, it can still make spiders!
pitched··on Colorado governor signs tractor right-to-repair law opposed by John Deere
Assuming that there is some sort of sensor that’s measuring these turn radiuses? What happens to the machine when the sensor malfunctions? Does it shut down (requiring work to stop), keep going (being a huge liability) or is there a box of them under the chair the operator can swap in and keep going? I think what’s being asked for here is option 3, not so much being able to modify turn parameters.
pitched··on Colorado governor signs tractor right-to-repair law opposed by John Deere
The way I understood the issue (as an outsider) is that they weren’t offering things like gaskets for sale. Sure, I can pull out the old one if it pops but what do I do now? That plus there being a remote kill switch if someone does figure out how to manufacture replacements…
pitched··on As I am currently in a war zone, I don't have many options for cabling
I’ve found that having a charged, exposed cable laying around will start to rust within about 6 months. This is from cheap phone cables so it being copper-coated instead of full copper is likely.

I’ve also heard of cathodic protection or electronic rust proofing doing the opposite though? Maybe it has to do with moving charges vs static charges? Or ground a cable preventing rust vs charging it accelerates rust?

pitched··on Apple’s Best Hope for New Headset: a Smartwatch-Like Trajectory
The headsets that exist today are very, very isolating. The whole idea behind them is to bring you somewhere else! To get AR right though, we need to be talking about something more like a projection like Google Glass. To bring the interface to you instead of bringing you to the interface means that pass-through must work when it’s powered off.
pitched··on The Anti-Productivity Manifesto
I think it’s a lot easier to become productive and efficient at work than it is at home (or generally tasks for yourself). Because of the structures built to support it only usually end up in one environment. That imbalance is what I think leads to burnout.

But saying that the solution to productivity is… productivity… is just as bad as telling people to meditate instead of taking time off work. Probably true! But very unhelpful.

pitched··on A reason why Mac speakers sound better and louder than most
For a quick starting point, try gcore[1]. Open the file it pops out into your favourite editor and hope that search works.

For gentler introduction, look for CTF sites. The one that gets recommended most is tryhackme.com. There are a bunch of great ones though.

Looks like the qcal link got double-pasted. Here it is if anyone else is interested: https://sr.ht/~psic4t/qcal/
pitched··on A step forward in understanding Fragile X syndrome, a cause of autism
If the neurons that are weak are the ones for processing external signals and having them override internal signals is the goal, maybe it’s as simple as a cold shower every day.
pitched··on Andrej Karpathy is joining OpenAI again
Doom source code was released on December 23rd, 1997 (1). That was while it was still relevant.

From the article linked: > The most common books used were Feeling Good and Helping Your Anxious Child: A Step by Step Guide.
pitched··on 80/20 Aluminum T-slot Building Systems – Build your Idea
That’s what the chart I linked says. To stand on a 1m length suspended on both ends, a 2060 might work but a 2080 should be safe. That’s just a bit smaller than a much cheaper wooden 1x4 though.

The reason I haven’t used these for a few past projects is that they can’t quite hold up under human-scale weights (1). Would be awesome to have something like this but steel!

pitched··on Motors for Makers: A Guide to Steppers, Servos, and Other Electrical Machines (2015)
The second Google result for this book is a chapter preview from the publisher: https://ptgmedia.pearsoncmg.com/images/9780134032832/samplep...

The first result is entire PDF though. I remember back in the old days being a poor student trying to save money spending hours trying to find scans of texts (or making scans in the library). Now it’s the first result in Google! Here’s hoping none of us need to make money through writing…

pitched··on Why developers never use state machines (2011)
Where is the line between a state machines and object-oriented? One encapsulates some state and provides a set of messages to modify it. The other encapsulates some state and provides a set of transitions to change it.
pitched··on Ask HN: ChatGPT et al. and NPCs
Proxy all the requests through a server you own and validate the game’s cd key or whatever before forwarding the request. Could also add a block list of known bad actors plus some rate limiting if that isn’t enough.
pitched··on Show HN: Timeretain – Track, visualize, and export your hours
I use my calendar for this. The event name is my notes for what I did. I find I forget to hit start (or stop) at the exact perfect time with these tools so they’re always only showing a partial view. With the calendar, I can go through and add in events for what I did in the morning or the day before.

Also, the best tool I’ve found for accountability is to try and predict what you will spend time on before hand. So I have one calendar for my plan that I make first thing in the morning and another for what actually happened.

> Burnout is: exhaustion, inefficacy and depersonalization

This tool is focusing a lot on the first and maybe the second but it’s that third one that’s the hardest to catch.

pitched··on Of course the attention economy is threatened by the Fediverse
In case anyone else hadn’t heard of this: https://github.com/aljazceru/awesome-nostr

From only a few minutes of reading (so I might be off), it looks like if multicast packets were saved by routers and you could ask for tcp-style retries later.

pitched··on Ask HN: Do you hate software engineering but love programming?
Engineering (and Software Engineering) is all about building a bridge that barely stands. Tuning the entire process to be cheap as possible with as little risk as can be stomached. It’s very concerned with what happened in the past, to feed into those decisions.

Science (and Computer Science) is all about getting a giant telescope into space. Tuning the entire process to discover and keep working when it finds some new and unexpected. It’s very concerned with what might happen in the future, and uses those predictions to feed into current decisions.

It sounds to me like you’ve got it backwards. It’s the science you don’t much enjoy. Maybe try your hand at something like project management to get closer to the engineering role?

pitched··on Impact of breakfast skipping compared with dinner skipping
> Compared with 3 meals/d, meal skipping increased energy expenditure. In contrast, higher postprandial insulin concentrations and increased fat oxidation with breakfast skipping suggest the development of metabolic inflexibility in response to prolonged fasting that may in the long term lead to low-grade inflammation and impaired glucose homeostasis.

So, it sounds like short-term fasting is a good way to stress the system. Long-term stress might lead to bad outcomes though?

pitched··on Tech companies are irrational pop cultures
It took me a moment to get it too. I think they’re saying that the internet wasn’t a waterfall-style design. It wasn’t a one-off big thing, it was a huge collection of small projects where most of them have since died because the trade-offs didn’t work. Agile is way more work than waterfall.

pitched··on Leaked Slack all-hands meeting reveals a ‘strong culture clash’ with Salesforce
Thank you, this is a really interesting framing!

What do you think the objective function might be that gets min/maxed by being dysfunctional? Something about minimizing the harm from poor decisions?
