yazaddaruvala··on Microsoft exec says Windows 11 kernel will soon be booting with Rust inside
The font parsing code was ported to 100% safe rust (other than the C FFI), and was 10-15% faster to run than its Cpp predecessor.

Make of that what you will.

yazaddaruvala··on The Great Electrician Shortage
> vacuums may or may not work (I think the latest PoE spec is like 95 watts?)

My vacuum is cordless anyways. Batteries solve a lot of these problems, and are typically more ergonomic anyways.

> What I don't like the idea of is needing to bring in a network engineer to troubleshoot my lights though

lol, yes. The hope is that you don't need a certification, and as such more people would be able to DIY or contract the job. If its MORE work/skill, then I agree that is not helpful.

yazaddaruvala··on Apple wins antitrust court battle with Epic Games, appeals court rules
Rather than allowing side-loading on iOS. I hope Apple is forced to open up its bootloader on iPhones.

Step 1: Go to the Apple store and ask to unlock the bootloader, they give you a form to void the warranty and Apple Care, they then unlock the bootloader.

Step 2: Wait for the Asahi Linux, Valve/Steam Proton, Google, and the Pinephone teams to showcase their skills.

My hope is literally:

Throw side-loaded Apps into a separate virtual machine with a different iOS, etc. No access to anything other than itself.

yazaddaruvala··on The Great Electrician Shortage
Should we even need that many electricians these days?

Nowadays, most houses should move to use power over Ethernet/USBC for all the lights, cameras, vacuums , toasters(with a small battery), and most of the sockets.

That way only big appliances (washer, stove, heater, etc) still need a real electrician to come help with.

yazaddaruvala··on Micro- and nanoplastics breach the blood–brain barrier in mice
If only they would take my blood!

In Seattle I've tried to donate blood multiple times over the last decade.

Every time, "because I've been to India in the last 5 years" they are unable to take my blood. Something about the risk of malaria. At worst, given a shortage, why not take my blood and analyze it? maybe even clean it (like with a dialysis machine)?

Talk about a dumb rule. Anyways... is there some other way to get this advantage? Are there blood letting doctors?

Take off requires a lot of resources, but maintaining altitude and speed are likely minimal additional energy.

yazaddaruvala··on Ban on Tenure for New Faculty Hires Passes Texas Senate
> Education is an investment in the future; encouraging the best professors

The best researchers do not always make the best educators. The best educators do not always make the best researchers.

Being good at research is a nice to have, but a facility like UT Austin should be hyper focused on attracting the country's best educators to help Texas' best students get (or create) the country's best jobs in Texas.

That said, the best educators are likely also attracted by Tenure.

yazaddaruvala··on AMD and Jedec Are Collaborating on DDR5 MRDIMMs at 17,600 MT/S
Thanks, this is what I'd love to understand better.

At the highest level isn't it all EUV? Why can't the laser print both patterns onto the wafer?

yazaddaruvala··on AMD and Jedec Are Collaborating on DDR5 MRDIMMs at 17,600 MT/S
With the continued evolution of chiplets, I’m annually shocked we don’t have DDR5 built directly into the processors same wafer.

The yield is maybe a factor, but that is solved with experience. Why is no company even trying?

Is it an IP issue? I seriously don’t understand (especially for phones) why it is still optimal to keep RAM separate.

Could someone help me understand this?

and I’d really appreciate leaving “upgradability” out of this conversation. That is a separate topic that can be had but not interesting to me right now.

yazaddaruvala··on Master Plan Part 3
Having ridden in multiple Tesla Ubers:

The drivers are consistently upset they hadn't switched sooner. What they tell me:

- They love the charging breaks at malls, etc where they can also take a deserved 20 min break.

- They love the entertainment between rides.

- They love the heat/cold remains on even when not driving - without "running the engine".

- They love not needing to use their brakes. Saving them money.

- They love that there are no fanbelts that can break, no oil needing to be changed, etc. Saving them money.

- One of them told me it is paying itself off 3 times faster than he had calculated because of the additional savings from maintenance.

yazaddaruvala··on Starlink internet is going from rural savior to unreliable luxury
Yes technically, but I think you're unlikely to notice it in practice.

In the worst case, because of buffering, your Netflix video might take an extra 10 seconds to start and then you'd notice no interruptions (unless you're skipping back and forth). But even that worst case would be unlikely to really be an issue.

For example, are you ever interrupted by someone else in your household turning on another TV? It would be similar.

You wouldn't want to share with your neighbor if they are actively abusing this with torrents or some other constant high bandwidth activity, but ideally you'd pick a neighbor you already know well and can trust.

yazaddaruvala··on Starlink internet is going from rural savior to unreliable luxury
It’s very unlikely you have 70mbps sustained usage. Typically it’s an average of peak per X mins.

You likely could save money by sharing your Starlink with a neighbor and neither of you would have much noticeable impact to bandwidth. Your latency might get slightly worse because of possible “noisy neighbor” but gotta ask if that latency is worth the extra $.

yazaddaruvala··on Can water solve a maze? [video]
Depends on the hardware being targeted.
yazaddaruvala··on Starlink internet is going from rural savior to unreliable luxury
Do you know if the issue of congestion is bandwidth, or if its bound by satellite to ground connections?

If its the latter, have you tried finding a neighbor or two and paying $60 each or $40 each?

yazaddaruvala··on For the first time, the Fed is losing money
What does it even mean for The Fed to have "negative equity capital"? Firstly, is this "equity" a short term book value vs long term book value thing? Secondly, they can literally print money.

> the Federal Reserve has suffered operating losses of about $42 billion since September 2022

Between 2020 and 2022 they quantitatively eased $2TT+, and then over the last 12 months have actively quantitatively tightened $0.500 TT [0].

$0.042 TT is literally change to them. They can chose at any time to pay it off by stopping the quantitative tightening. Even a quantitative easing at this level would be inconsequential.

Who is benefiting from a scary headline like this? or am I totally misunderstanding something?

yazaddaruvala··on Rust's Golden Rule
+1

I don't have the time to shepherd this RFC (or something similar), but I really wish that the whole Async ecosystem was built on something less error prone / magic-y than ThreadLocalState.

Its not ideal to ever have any "hidden" functionality like auto-propagation, but it would be way better than the current state of async Rust.

yazaddaruvala··on Credit Suisse’s $17B of Risky Bonds Are Now Worthless
> Countries don't all use their own currencies

Sure. I think this missed the point.

I didn't say/intend "a country / army needs to be backed by a unique currency"

I said, "For a token to be a currency, it needs to be backed by [at least one] army and [at least one country's] taxes".

e.g. The Euro happens to be backed by multi armies and at least Germany's taxes.

> Some countries don't have any armed forces unless you count the police.

Again, it isn't "their army" but it is "an army". e.g. Liechtenstein is backed by "Austria and Switzerland under an informal agreement among the three countries." https://en.wikipedia.org/wiki/List_of_countries_without_arme...

Anyways, if we disagree that is ok too. All of this is quite fuzzy really.

yazaddaruvala··on Epic’s new motion-capture animation tech
20 years ago Peter Jackson had a whole team to do it, across months, with Andy Serkis in a specialized suit, on a specialized camera rig, with amazing lighting and green screens. All to map to a single animation model Golem.

This was done on an iPhone, in subpar conditions, by 2 people, with regular clothes and background, for any/all humanoid models in under 90seconds!!!

Amazing!!! It’s the only word for it and it doesn’t do the accomplishment justice.

yazaddaruvala··on ChatGPT Has Submitted a Pull Request to Rails

yazaddaruvala··on Bing Image Creator
> They in fact do and

My point is nothing your saying is new or specific to OpenAI. These are problems with Capitalism and its influence over populations.

It is an important conversation, but a distinct and orthogonal conversation that is distracted by involving AI.

yazaddaruvala··on Bing Image Creator
> OpenAI has massive power to censor what people can reason about with GPT.

This is like saying, the transportation of <city> has massive power to censor where people can travel about within a bus.

GPT is a tool for reasoning, but humans need to be able to reason on their own! and by using multiple tools!

Of course every tool should help and enhance every human, but every tool has its limitations. There is nothing unethical about calling out a tool's limitations and ensuring humans use it accordingly.

> one advantage Bitcoin does not have, that fiat does, is an armed gang with orders to enforce its use by all citizens.

Nail on the head!

The only difference between "tokens" and "currency" is an army and taxes!

yazaddaruvala··on Credit Suisse’s $17B of Risky Bonds Are Now Worthless
If the US gov collected taxes in BTC and funded its budget in BTC and borrowed its loans in BTC and paid that interest in BTC,

Then the US gov would have the ability to control the circulating supply of BTC.

Think of it this way, BTC caps out, then the US gov HODLed 50% of all BTC for an uncertain amount of time (call it a decade). The rest of the world starts to take risks accordingly and make investment strategies based on “no possible inflation, because BTC”.

After a decade+ of BTC HODL policy the US gov decides to release 5% it wouldn’t be “printing BTC” but it would still certainly be “quantitative easing” and the extra supply of BTC would result in very much the same inflation as we see today.

There is no scenario where the largest governments of the world cannot directly control the supply of circulating money! (Which is the only money that really matters).

yazaddaruvala··on Build full “product skills” and you'll probably be fine
> It seems to me that the advice given here would be more applicable to someone who only coded long enough to move into engineering management -- anyway something about it bugs me and I don't think I'd follow it exclusively even if I was starting today

The advice here is clearly meant for someone who wants to invest in themselves to provide food and shelter for themselves and/or a family in the future. (Ie “doing all this hard work for nothing… AI will make my future job obsolete”).

The advice is spot on. Soft skills are hard to learn, harder to teach, and allow for flexibility with regards to the tool used.

> anyway something about it bugs me and I don't think I'd follow it exclusively even if I was starting today.

I’d be you like the money but don’t seem to want it as much as you want to solve deterministic puzzles (“not interested in becoming a manager” ie “not interested in maximizing career/salary growth potential).

What bugs you seems to be that you can’t yet see the puzzle left for you to work on once GPT-12 makes coding obsolete and software architecturing obsolete.

A long time ago I got some good feedback, “You were hired because you typically know the right answers and/or know how to find them. You were promoted because you also seem to know how to ask the right questions, and that is significantly harder.”

I’m relatively certain it’s analogous to Carmak’s advice.

yazaddaruvala··on Growing crops under solar panels
I just added this comment below: https://news.ycombinator.com/item?id=35101717

A lot of farming NEEDs sun protection for better yields. Currently farms that don’t have sun protection over compensate by over watering (also could reduce yields).

Not to say every farm should have solar panels but it’s very likely a double digit percentage of farm land would benefit from agrovoltaics.
