jdewerd··on Electromigration Concerns Grow in Advanced Packages
Oh good. I could have sworn I heard that the timed exclusivity requirement came from the Dubai side, but in any case I am glad to hear that they are more widely available now.
jdewerd··on NASA lays out how SpaceX will refuel Starships in low-Earth orbit
Spin after docking, of course.

Pushing the liquids is not the hard part. Settling the liquids in 0g is the hard part.

jdewerd··on Tesla failing to deliver Semi-trucks on time to PepsiCo, Sysco, UPS, and Walmart
It was, but it was the politics that swung the opinion pendulum from pathological "admire wins, ignore losses" to pathological "ignore wins, disparage losses."
jdewerd··on The Myth of the Second Chance
Your meta-commentary is just as vapid as mine.
jdewerd··on NASA lays out how SpaceX will refuel Starships in low-Earth orbit
It wasn't intended as a jab, spinning it up to settle the propellant for transfer sounds like a good idea to me. Of course, failing to exit the spin is still mission-ending but they'll figure it out.

Now we just need the Attenborough voiceover about the mating habits of starships as they spin through space.

jdewerd··on Electromigration Concerns Grow in Advanced Packages
I dunno, working hard to prevent the spread of an environmentally friendly innovation to maintain bragging rights rather than trying to spread it as far and wide as possible sounds like a very Dubai kick in the environmental knackers to me.
jdewerd··on NASA lays out how SpaceX will refuel Starships in low-Earth orbit
Ohhhh, is that why it was spinning going into the reentry attempt?
jdewerd··on The Myth of the Second Chance
Because the goal is to discredit the 2/3 number by any means necessary.
jdewerd··on Jimmy Carter UFO Incident
I know, right? Of course, the American Electorate was quick to rectify its accidental moment of sanity by promptly voting him out after he installed Volcker and hiked rates to the moon (and then rewriting history to say that Carter was a bad president and Reagan tamed inflation).

He was not the president we deserved, but he was the president we needed.

jdewerd··on Why I Don't Invest in Real Estate
No, let's be honest about the cause of it: it's because they want their housing value to keep going up. The parade of excuses is much less convincing than the plain, obvious, dramatic financial incentive.
jdewerd··on Why I Don't Invest in Real Estate
The "home is your piggy bank" mentality is the cause and motivating force behind NIMBYism. It's not only in the article, it's prominently in the article.
jdewerd··on Google made me ruin a perfectly good website (2023)
The complaint was about Google's "talk to the hand" onboarding/feedback process, not the preferences of advertisers.
jdewerd··on CoreNet: A library for training deep neural networks
They've been using them, too. Auto OCR so selecting text in images Just Works, image enhancements, Siri. I'm sure LLM Siri is in the works. Scanning your photos for CSAM. Let's hope that last one is more reliable than Siri :/
jdewerd··on Xzbot: Notes, honeypot, and exploit demo for the xz backdoor
Yeah, we should probably expect that there are roughly 1/p(found) more of these lurking out there. Not a pleasant thought.
jdewerd··on Eclipse viewing at 30k feet: Delta to offer path-of-totality flight
It's a math/engineering joke. A control system is considered unstable if there is a pole (a mathematical singularity, not Polish person) on the right side of the plane (the complex plane of the Laplace transform of its closed loop transfer function, not an airplane).
jdewerd··on How ChatGPT made me lazy
My expectations are normally on the floor, but when accusations of laziness start to fly I think it's 100% fair to note the wide discrepancy between the accusations on one hand and the effort on the other.
jdewerd··on 100kHz to 6GHz 2 port USB based VNA
VNAs are fundamentally narrow-band instruments. This:

> The RFsoC 4x2 board has 4x RF ADCs (5 GSPS) and 2x RF DACs (9.85 GSPS)

is like chasing after a fly with a sledgehammer. It wildly over-specs something that is almost completely useless for the task at hand (real time bandwidth, mass of hammer) while it wildly under-specs the important parts (frequency range, directivity, agility of hammer).

jdewerd··on Ask HN: How many of you Apple developers still use Objective C?
Do you expect people to periodically repeat failed experiments just so they can provide you with up to date information? You are always free to ignore it.

In any case, this particular observation is timeless: language bridges always have trolls under them. Maybe your project can get away with using the bridge anyway, but maybe a highly critical API gets locked out because the bridge deals poorly with variadic arguments or object lifetimes or templates/generics or nested objects or latency/overhead assumptions or.... whatever, and the troll conks your schedule on its head. Try to minimize exposure and prioritize steps to de-risk the bridge.

jdewerd··on How ChatGPT made me lazy
Evidently we don't need ChatGPT to make us lazy. ChatGPT, could you correct the grammar in these posts?

    Sure, here are the corrected versions of the posts:

jdewerd··on GlobalFoundries wins $3.1B in CHIPS Act subsidies for NY, Vermont
Everyone involved with floating the dollar and running a deficit understood that it would pump the asset sector and dump the export sector. There were fights about it. Keynes got himself ejected from elite circles by lobbying a bit too hard for his pet alternative.

If you want a more visible and recent datapoint, look to the perennial fights in the UN over the opposite, where a country that promised not to devalue their currency devalued their currency. Note that these discussions generally start from a point where everyone understands why it might be desirable to devalue one's currency, pumping exports & the real economy while dumping assets. This is macroeconomics 101 stuff.

The surprising thing is not that high tech manufacturing left, it's that for a while it was actually able to compete with a money printer for access to talent and resources.

jdewerd··on Pakistan cuts off phone and internet services on election day
Standardized testing does not aim to be a perfect evaluation, it aims to be a good enough evaluation that can be made highly resistant to corruption/bribery relative to its qualitative alternatives.
jdewerd··on Anchovy spawning causes temperature swings and turbulence in ocean layers
Every place I have worked at has remained seated for the "standup" because it's tiring to stand for that long.

(For those who aren't looped into the irony: the entire reason why it is called a "standup" is because you are supposed to stand up to create subtle pressure against long unnecessary meetings. Sitting down for a stand-up isn't just a quirky paradox of jargon-meets-reality, it is a fundamental rejection of the entire premise while cynically parroting the terminology itself.)

jdewerd··on Building an early warning system for LLM-aided biological threat creation
My experience, not my opinion. I personally tripped over the checks many times, back before they got institutional authentication smoothed out.

I regularly hear bio researchers claim firtshand experience that there are no checks, but then it turns out they were using institutional names, credit cards, and shipping addresses the whole time, so what they actually experienced was a lack of false positives rather than an absence of checking.

jdewerd··on Apple reports first quarter results
I don't think it's time for an obituary that counts the spinoffs and devkit revenue. FB and Apple got the timeline wrong, but the AR story isn't over. Looking down at phones still fundamentally sucks and eventually AR will be good enough.

Point of comparison: Steve Jobs started talking about the iPhone when someone asked him about the next big thing at the Macintosh premier in 1984. 10 years later, he was fired from Apple and working on bespoke workstations. 20 years later, Palm/Blackberry owned the smartphone market. 30 years later, Apple owned the smartphone market. These stories take time.

jdewerd··on Building an early warning system for LLM-aided biological threat creation
> minimal control, i.e. checking DNA / RNA / protein sequences

They were already doing this 15 years ago.

> It's frankly ridiculous there are no checks in place right now.

It's frankly ridiculous that you think this.

jdewerd··on I don't want anything your AI generates
Yeah, but a few years is no longer unthinkable and it will definitely not take a few decades.
jdewerd··on Google search drops cache link from search results
The other day I did an AI related search and had zero organic results above the fold. It has begun.
jdewerd··on Intel's Humbling
Absolutely ridiculous. No, Apple did not juice the M1 by giving it better cooling than x86. Quite the opposite, they took a big chunk of their design+process wins to the bank and exchanged them for even cooler and quieter operation because that's what they wanted all along. Cool and quiet was a deliverable.

It's absurd to point out that apple could have gotten higher perf from x86 at higher power as if it's some kind of win for intel. Yes, obviously they could have, that's true of every chip ever. They could take it even further and cool every macbook with liquid nitrogen and require lugging around a huge tank of the stuff just to read your email! They don't, because that's dumb. Apple goes even further than most laptop manufacturers and thinks that hissing fans and low battery life are dumb too. This leads them to low power as a design constraint and what matters is what performance a chip can deliver within that constraint. That's the perspective from which the M1 was designed and that's the perspective from which it delivered in spades.

jdewerd··on 2023 Letter
Agreed, the West has ben better at power for the last few hundred years. I'm responding to the laughable idea that this perspective is exclusive to the west. It clearly isn't, and besides, imperial China seems to be on the rise again, so in the next century they might even grab back the "stinkiest asshole in the room" award.
jdewerd··on Real estate giant China Evergrande will be liquidated
5% on $100B can patch one hell of a balance sheet hole.
