> Why wouldn't he put up more Tesla as collateral?

Because he didn't. If Elon Musk had easy access to Tesla-as-collateral, he would have put more of it up as collateral.

> How do you know he can't get more financing?

Because he's cutting himself out of the deal. That suggests he has run out of options to get money.

Besides, surprise +50 BPS from the Fed just made it incredibly more difficult to get financing from the banks, and -20% to TSLA's stock price in the past couple of weeks compounds upon this fact, and makes it more difficult to use TSLA-shares as collateral.

> How much BTC, Doge and eth does he have?

Whatever amount he has, it is worth about 25% less than two weeks ago.

EDIT: I mean, maybe Musk has the money and is just trolling all of us? Which sounds on-brand for him frankly. I don't know why he'd want to do that, but he's not exactly a "stable" figure.

I really appreciate the writing and work that was done here.

It is amazing to me how complicated these systems have become. I am looking over the source for the single triangle demo. Most of this is just about getting information from point A to point B in memory. Over 500 lines worth of GPU protocol overhead... Granted, this is a one-time cost once you get it working, but it's still a lot to think about and manage over time.

I've written software rasterizers that fit neatly within 200 lines and provide very flexible pixel shading techniques. Certainly not capable of running a cyberpunk 2077 scene, but interactive framerates otherwise. In the good case, I can go from a dead stop to final frame buffer in <5 milliseconds. Can you even get the GPU to wake up in that amount of time?
There is a nonzero chance that all of the "growth" that we've seen over the past 14 years was just fueled by cheap credit. If we can't avoid a recession after raising rates by 100bps then we've had a false economy the entire time. Hope you got to ride the wave while you could.
Put a thermocouple in some hairdriers and you'll find some get well over 400 Celcius (750F!).

They just rely on the fact air has a low thermal mass, and it's easy to just keep it slightly further from your skin if necessary - the air quickly cools with distance as more room air mixes in.

You can write a program that locks up your computer in most any language, it's called a fork bomb. Of course, there are guards against the most basic versions these days, but the point still stands that there's nothing stopping you from writing an endless loop that takes up more and more resources.

In 1966, at age 18 I came home from the first year of college very tired. No amount of sleep made me feel rested. Everyone, including me, thought I had mononucleosis. I tested negative for mono and my family doctor said I had a virus that imitated mono, get some rest and it should go away.

In 1980 when CFS hit the news as "yuppie flu", the initial description was 'a virus that imitated mono.' My family doctor got it right 14 years earlier.

It is difficult to be diagnosed with CFS because you have to eliminate every other cause of tiredness first -- MS, cancer, etc. One doctor told me that tiredness was a symptom of every disease in the book. I never had unlimited funds at my disposal, so I never pursued eliminating all other causes. Eventually I concluded that if it had been serious I'd have died already. My last doctor finally put on my chart 'he is chronically tired and we don't know why" or words to that effect.

As for my experience with it, it has been lousy. Why wouldn't you be depressed if you can't go where you want (or your spouse wants), can't work full time, live poorly as a result, etc. Eventually you learn to live within your limitations and don't push yourself too hard - because you will pay for it later.

My advice is kind of glib: don't let it get you down. I have a belief system that has helped me tremendously in dealing with it and a spouse that has reconciled herself to not going out to eat very often (never, since the pandemic), not socializing greatly (she is introverted anyway), and not taking long vacations - this she misses. Find yourself both - a belief system that supports you (I don't want to take the discussion in that direction) and family and associates that understand.

And they haven't found a cure. When they find a real one, you will hear about it. So don't waste your time and money on snake oil. If it works for you, do it. Less coffee and sweets works for me, at least it helps matters.

And thanks for asking. I'm not a coder by any means so I usually just lurk here. But I've wanted to put this in words for a while.

Unless something changed since 2.0.9 (last time I did anything relevant in Scala), only one level, it isn't clever enough to rewrite mutually recursive calls.

This was driven by extended 0-ish% interest for an entire recession cycle. Unable to get "safe" returns, money chased more dangerous classes of assets and inflated prices.

Inflation and a return to nonzero interest means capital gets to retreat to safer ground, pulling the rug out of stupid unprofitable startups that can only make money with head-in-the-clouds IPO valuation or FAANG acquisition.

Do you regularly run out of power on your chain powered bike though? I get the feeling this system requires a battery (it even mentions battery in the article), and most of the actual power comes from that. The question is, will the generator make enough power to get you moving if the battery is totally flat? I kinda feel like no, you'd have to sit there and pedal it just to charge it up, and then it would move you a few feet. Or you're going to be pedaling really fast, and moving nowhere.

> having lost enormous volumes of military equipment?

Any military operation includes the planning for acceptable losses in combat.

We keep on hearing about ships getting destroyed, that were not, then re-emerging. https://www.forbes.com/sites/davidaxe/2022/05/09/a-journalis...

We don't know how much Russian military equipment has been destroyed, but it appears to be some. We do know a large amount of Ukrainian military equipment has been destroyed also, and that Ukrainian logistics are on the receiving end of Russian airpower and tactical ballistic missiles (iskanders). In most cases, Russians have established some level of air advantage, artillery superiority, and missile superiority (iskanders > Tochkas).

Logistically, the Ukrainians are losing this war in a big way.
How did it go? It sounds super interesting.
In many cases, yes.

Especially when there are low hanging fruits that could save billions that we haven't touched, not because the science is hard, but because the political willingless/empathy is low.
For reference: https://www.iso.org/standard/59579.html

This work happened in 2009. It was originally based on Ruby 1.8.7, the final draft was completed in 2010, and didn't cover the full standard library at the time. Took two more years to get through ISO.

If you don't have an encyclopedic remembering of Ruby version releases, when that draft was complete, the current released version of Ruby was 1.9.2. Ruby underwent huge changes between 1.8.7 and 1.9.2; many other languages would have characterized it as a major version change at the time; Ruby didn't follow semver back then.

So basically, it was already out of date well before it was final, and never was updated. So it's really irrelevant today.

Why did this even happen? Well, supposedly there are some requirements for Japan government work that require a spec, and so a spec was produced. That's my recollection, anyway.

I think the poster is arguing that the things we call merit reflects the ability to do the job well. Any system of hiring has to consider the ability to hire the best person for the job. Quotas are an open-admission we can no longer do this. Affirmative action is trickier as some affirmative action can be useful in correcting bias and can actually improve hiring. Too much once again steers us away from the best person for the job.

This is important and tricky as if we have across the board decreases in hiring the best person for the job we end up with a less productive economy. This means our hiring practices directly compete against other aims like solving poverty.
> Why do people think they have a better idea of his abilities than those who work with him?

It appears your argument is, "Elon is a great engineer, therefore he can't be messing around with his Twitter acquisition deal."

Your mistake is assuming that a great thinker cannot be mistaken, even outside his domain. A counterexample is the scientist who pioneered PCR. Kary Mullis won a Nobel Prize for his efforts! And yet he also believes in astrology and that HIV is not the cause of AIDS.

There's no reason to think that Elon Musk (who appears in no danger of winning a Nobel Prize) does not have his own goofy thoughts and actions, one of which appears to be making an insincere bid to buy Twitter just to make himself look big while weakening them. Time will tell whether that's the case.

Boring Midwestern City that's not even a 3rd-tier tech hub. Other boring Southern city that's also not even a 3rd-tier tech hub. Buyers are having to take on the risk of having to cover any extra over appraisal in cash, consistently, while that used to be rare (and, yes, usually for "I am super invested, emotionally, in getting this particular house" reasons).

My unremarkable suburban house in a boring city that's been building housing constantly and extensively for the last 10 years, is up like 25% in value over the last 2 years. We thought, based on extensive experience in this market, that we were already paying a bubble-induced premium of 15-20% when we bought it (possibly no longer true—thanks inflation). WTF.
You don't need to prove it. You just need to justify the number you show.

For example: you build a feature to notify customers via email that they have a balance due. The email includes a link with UTM tracking stuff. You also have metrics as to who pays and when. So now you can say "X number of people paid their balance within Y hours of an email being sent out, and within Z minutes of the email linked being clicked" and total up the amount of balances paid. Sure, your feature isn't 100% responsible for enabling that balance to be collected, but it deserves to say it contributed to a portion of the collected balance value.
What you are describing is called a Bona Fide Occupational Qualification (BFOQ). The specifics of what sort of attributes might be covered for what jobs is something courts hash out, but broadly: if you're hiring workers for a warehouse it's fine to require workers be able to lift boxes. If you're hiring airline pilots, it's fine to turn away blind people. Etc.
> The gasoline engine only serves as a generator, it is not mechanically connected to the wheels.

The Volt can operate in a series hybrid mode, but there is also a mechanical connection that is engaged at certain speeds where it's more efficient to just direct drive rather than double-convert the energy from the combustion engine.
I learn about in the last house I had which was in FiOS (fiber) available area and I of course ordered it and when they were installing it I asked the guy a bunch of questions and one was "who are you getting the signal across my Cable TV Coax" and he told me they were using MoCa so I googled it later and thought wow, that's interesting.

Then Later I moved to this place and there is no FiOS but I have mm-wave 5G (2Gbps) but there was no Ethernet cable in the house so I thought, hey, I know, I will use that MoCa thing, and it worked like a charm, got my signal from the CPE antenna unit mounted on my Garage (best signal) down to my lab in my basement.

You make some good points, and I'd venture to guess that you're handy with a bike, but for the vast majority of people who use bikes, what you're saying about maintenance is totally irrelevant.

I'm also handy with a bike, and I've spent some time volunteering fixing up used bikes for resale. Here's what I usually saw:

> Chains wear out and require replacement, usually together with the rear sprockets. Front rings wear also; about once every three times you change a rear sprocket, you have to change the front rings which, for entry level bikes is usually most cheaply done by getting the entire crank set.

This is true, but very, very few bikes ever get the kind of miles put on them to wear out a chain. If you ever wear out a chain, you're conservatively in the top 3% of cyclists by miles ridden. Mostly chains die a slow horrible death by being left outside all winter and turning entirely into a rusty immovable mess. If they're completely beyond saving, you cut them off with a hacksaw, put on a new one, check the cassette, and move in to the next neglected thing. I've never replaced a cassette other than on my own bike, no matter how nice or shabby the bike looked.

In the extraordinarily unlikely case that somebody manages to wear out the chain on a cheap bike, they're almost certainly as well off just buying a new cheap bike. Everything on a cheap bike is crap, and by the time you've killed a chain, something else will need to be fixed. Unless the labor is free (mine was, that was the point), you're quickly into more money to polish a turd than to buy a new one.

If by "entry level", you mean "inexpensive from an actual bike shop", then yeah, it might be worth replacing some drivetrain components. Even so, you'd be dealing with the unicorn rider who rides enough to wear out a chain, but also doesn't want to upgrade to a midrange bike.

> Typically, a multi-speed rear cassette must be removed in order to replace a broken spoke, which is a PITA. This is because it is larger than the hub, and is right next to it, blocking access to the spoke entry holes on the drive side. You need chain whip to prevent the hub from turning...

I've broken and replaced spokes. It's pretty rare, and it requires special tools. Most cyclists can't adjust a derailleur, and a surprisingly large number are incapable of fixing a flat.

Everything you're saying is true, but for nearly everybody, a broken spoke is a job for a bike shop. The barrier for replacing a spoke for most people isn't having the tools, it's knowing how to use them, and specifically how to re-true the wheel. I don't mean getting it perfect on a stand, I mean getting it rideable using the brake pads for a reference.

I know somebody who used to race competitively. He has a shop do all his maintenance because he's not even the slightest bit handy, and I can only assume it's not for the lack of opportunity to learn while he was riding competitively.
Ask HN: How to keep up to date doc of a system architecture?
Hi,

I have helped architect embedded vision system.

It's a piece of hardware with a camera, AI accelerator, processor, RT processor etc.

A lot of stuff is going on in this project, also a lot have changed in last just year.

It was easy for me to do the first diagrams in Keynote and present the architecture.

But now it grew so much, that I no longer feel control over it.

I get a lot of feature requests and questions about system behaviour, and it takes me longer and longer to respond.

Is there any software that could really help write down, visualise and keep history of such architecture?

Ideally I could contribute on pieces of it with teammates.

How would you approach such problem?

thanks.

> Facebook grew into institutions with extremely light content moderation

Facebook used to have a strong social cost to being a dick. Then as photos started to explode, they stopped nipples pretty quick.

in 2009 they had a fully formed photos policy and moderation system.

Moderation has been there since the start and its there to stop normal people getting barraged by niples, pictures of dead things, and spam.

Self moderation doesn't really scale when you go over 400 people in a group. After that its drama, then after that it turns into 4chan.
> we'd see the same problem everywhere at the same scale

we do. Every C app implements its own linked list or hash table library. The entire Scheme community is nothing but toy interpreters of various stages of completeness (you can tell a project is serious when they implement call/cc). How many game engines do you think exist? It's a meme that game devs like to spend more time on their pet game engine than actually making their game. How many ORMs do you think exist for <language-of-choice>? At least half a dozen. At least. For any given language. Python, Ruby, Go[1]. ORMs, in particular, seem to get created over and over again. Probably because they are trivial to implement and allows one to voice their opinions on SQL abstraction (bike shedding).
