ptero··on How to talk to anyone and why you should
I cannot agree with that. Do not be shy about trying, but do not be a pest either. There are many times when interruptions are not good for both sides. My 2c.
ptero··on Addressing Antigravity Bans and Reinstating Access
Register your own domain, use a third-party provider to handle actual sending and receiving (I use proton, which makes the setup very easy), forward your Gmail to your personal domain address and as renewals and reminders come in switch your email on services to your personal domain.

After a year or two losing Gmail becomes an inconvenience; after a few more years it is nothing. As everything is now on your own domain name you can switch providers without affecting anything.

That's what I did about 5 years ago and my only regret is not doing it earlier.

ptero··on NASA announces overhaul of Artemis program amid safety concerns, delays
> N1 failure is attributed mostly to Korolev - Glushko rivalry that resulted in N1 lacking engines in time.

That is a viable version. But I think this was one of the problems and there were plenty of others. While Chertok does point to the engines as a major problem, he also admits that the whole system became way too complex to succeed.

His description of electrical components (for which IIRC he was the chief engineer) and checkouts is telling. He also describes the feeling of "good envy" as the Russian engineers were listening in on comms between the Earth and the Apollo 13 during its mission. Which drove home the point of how much advantage US had, at least in electronic, and how powerful it was for its successful lunar program.

> It's all a sad story of unchecked emotions leading to monumental waste.

I have a softer view. Both Korolev and Glushko wanted their own leadership, which is normal. Korolev ran his shop in a dictatorial fashion, as that was the only way he could operate efficiently. Which is also fine and can produce spectacular results (and it did early on). But it comes with its own risks, including motivating strong leaders to branch out. I would not call it unchecked emotions that Glushko, after many years at OKB-1 went to run his own projects.

Living in a someone's shadow while under his dictatorial control is not for everyone. I can see the arguments for both sides. My 2c.

> inexact quote: "You know, we're throwing towns into the sky" related to the early mishaps of R-7 program development

I have not looked at the source (in Russian) for several years; now that I am curious I will check at home tonight. But as far as I remember "we are shooting towns into the sky" remark was not in reference to the R-7, but in reference to N1-L3, a hellishly expensive competitor to the Apollo manned Moon mission rocket. The meaning of the phrase was that each and every test should be taken extremely seriously as the cost of each flight is comparable to the cost of building a new city.

R-7 was developed much earlier when Korolev and his team at OKB-1 were iterating rapidly on much cheaper models that were primarily funded as rockets for strategic thermonuclear strike warheads. The civilian (Sputnik and later Gagarin) flights were an offshoot of that and were small enough that it happened as a side project. R-7 was a comparatively simple and cheap design, which may be why that family became a workhorse from the late 50s to carrying crews to the ISS. And the super expensive N1-L3 was a stillborn.

That's my recollection, need to recheck the sources.

ptero··on Sub-$200 Lidar could reshuffle auto sensor economics
Not an expert, but main challenges with laser coherency are present when shaping the output using multiple transmitters.

For lidar you transmit a pulse from a single source and receive its reflection at multiple points. Mentioning phased array with lidar almost always means receiving.

ptero··on We're no longer attracting top talent: the brain drain killing American science
This, as written, is just an idea. Lots of forward looking statements on how the EU must do this and that and no explicit promise to offer funding to all affected US scientists. Not even many details on the funding. Is it the same funding? Equivalent funding? Some funding (how much? what are the conditions? etc.).

Not claiming that this will not entice anyone over, but it is far, far different from the original claim. Sorry.

ptero··on We're no longer attracting top talent: the brain drain killing American science
> German universities are now telling any US researcher who looses their funding that they will be funded at a Germany university

Is this true? Is there a link to the policy? Anything is possible, but this sounds fishy. German research funding isn't known for either generosity or particularly wide reach.

ptero··on I’m joining OpenAI
Humans are social animals and good social skills is a major benefit almost everywhere, including at work. This does not make most people juliuses.
ptero··on Lost Soviet Moon Lander May Have Been Found
They never actually put a full effort into building a consumer oriented economy.

The authorities would say something about a new food program or a housing program but only as motivational goals. Main players always saw getting people less economically dependent on the state as a major threat.

Making people economically miserable was never a goal, but when building consumer economy would start showing promise the state would reestablish control (see for example Kosygin reforms).

ptero··on Euro firms must ditch Uncle Sam's clouds and go EU-native
A much better goal would be to ditch dependence on a single company and become, as much as possible, cloud provider agnostic. Not that I mind giving US big tech grief -- they earned it in spades.

But if you wrestle your technology chains from one evil master, do not willingly give it to another, even if he looks more benevolent today. My 2c.

ptero··on The '3.5% rule': How a small minority can change the world (2019)
> A reply on social media is taking a stand?

No. I only said that spreading information that there is dissent does not require taking to the street.

ptero··on The '3.5% rule': How a small minority can change the world (2019)
The counter argument to that is in the age of the social media there is no need to take to the streets to show that there is dissent. Everyone the folks on the street could reach will know about the dissent anyway.

Motivating other people to take a stand -- I do not think this is true either. A fraction of the folks who would support the issue regardless may join the protest on the street. But that would be those who support the issue already.

Change comes from the ballot box. Enough people in the street might influence the next election (sometimes for the issue they are advocating; sometimes in the opposite direction). But 6+ months from the next election the effect I suspect is small. My 2c.

ptero··on Macron says €300B in EU savings sent to the US every year will be invested in EU
The cited rationale is a perfectly reasonable take.

But most of the world is in the same boat of "large budget deficits and growing government debt". It will be "interesting" for bond issuers and most investors and "exciting fishing" for hedge fund sharks over the next 10 years or so.

That said, I do not agree that it is 100% politicians. At least in the US, that path has been virtually unavoidable after the fiscal spending by G.W. Bush on the 9/11 wars and fully set in stone after 2008 subprime crisis. For the last 15+ years politicians could slow down or speed up the transit a little, but getting off that train has not been an option. My 2c.

ptero··on Significant US farm losses persist, despite federal assistance
The reason for keeping eggs in a fridge is different (primarily washing vs not washing). This has been discussed a number of times at HN.

Here is an example: https://news.ycombinator.com/item?id=19815155

ptero··on Danish pension fund divesting US Treasuries
It did not go into a hyperinflation after the WW2, when the US debt load as a share of GDP was even higher than today; and deflated in the same way US is likely to do it now (bond rates forced way below inflation with yield control).

I am not saying that the process will be pleasant for the US or its citizens. But it is not without precedent and is extremely unlikely to cause hyperinflation. My 2c.

ptero··on Danish pension fund divesting US Treasuries
Warnings about the deficit are spot on. It is a safe bet that the country with government that spends 50% more than it takes in as taxes will not give above inflation return on its government debt. As a side note, most of the "Western world" is in the same boat (spending way above the long-term ability to pay, so eventually will have to default-by-inflation on bondholders).

But I am sure the poster you are responding to was criticizing the take about US splintering into parts due to armed unrest within the next 5 years. Which sounds completely nonsensical to me as well.

ptero··on Targeted Bets: An alternative approach to the job hunt
Luck plays a big role, but it is not just luck. One can apply in a way that significantly stacks the deck in his favor.

So absolutely reach out to your network, study the current market and find your edge. It might still be poker-style games which you can still lose because of luck; but doing that gives you starting hands with two aces. My 2c.

ptero··on The $200K Developer Dream Is Over – Here's the Reality in 2026
> And why is CS not in STEM?

It sure is. If I said that it is not it was a typo.

What I was saying is that today I see a non-CS STEM major plus a CS-like minor as a better ticket for an undergrad (who will enter the job market in the next 2-4 years) than a CS major. Which was not the case for the last almost 30 years, when a pure CS major gave many folks an excellent start. My 2c.

ptero··on The $200K Developer Dream Is Over – Here's the Reality in 2026
It really depends on the person. This may be an unpopular opinion today, but I strongly believe that someone doing what he loves will statistically be both happier and better off financially than someone in only for the money. So whatever makes their ears perk up: EE, chemistry, mechanical, math, physics, biology, etc.

And, as a complement, pick up a "computer-ish" minor to learn how to make a machine do your bidding. My 2c.

ptero··on The Nobel Prize and the Laureate Are Inseparable
Perelman is a strange character; IIRC he declined several times first without bothering to give a reason. Then, after being asked enough times, came up with a "I am not a hero and such awards are irrelevant" as a somewhat acceptable version so those pesky folks would leave him alone. Thus I would not use him as an example of the right way to deal with a prestigious award.

That said, the Nobel medal to Trump circus is beyond ridiculous.

ptero··on The $200K Developer Dream Is Over – Here's the Reality in 2026
TLDR: "previous years of boom provided 100k jobs straight out of college, 200k jobs and a guaranteed path to wealth soon after that. That time is over."

Right. And this, IMO, is not a bad thing. We had a long, multi-year bubble and bubbles are not good for anyone. Deflating bubbles can be painful, but they are less painful than bursting ones.

And the current software bubble is deflating, not bursting -- there are still plenty (say, compared to the last 50 years average) of jobs where a good engineer comfortable with programming will make a very good living. So do still learn CS or SE in college, but as a minor to another STEM field. My 2c.

ptero··on Statement from Jerome Powell
I came in to say the same thing -- major, major respect to Powell.

I am not a big fan of his earlier policies (or of Greenspan's and anyone after him for that matter). His "unlearn the importance of M2" did not age well. He made the tail end of the ZIRP more painful than it needed to be. But those were honest mistakes from a public servant who did his best and believed in what he is doing.

And standing up for what he believes is right, against this insanity from the president is the gold standard of what we need from public servants. My 2c.

ptero··on All my new code will be closed-source from now on
I am not absolutely sure, but I do not think so.

Being old(ish) I recall in the early 90s Stallman advocating for (and mostly winning the argument in the tech circles at the time) open source as the primary tool for freedom to build things. With financial motivation possible, but completely orthogonal to the development of the open source software.

And how his argument (he was also a strong proponent of freedom to fork and improve in ways that the original developer did not do/want/agree with) was used against him in the early Emacs-XEmacs wars. When he tried to advocate that developers should support his Emacs version because he was the one who built Emacs (with tech retort being that his version sucks, he does not want to let others change it, so the community will build the features they want in XEmacs, thank you very much).

I think viable financial models of the last 15-20 years morphed open source into something different (in a kind of embrace-extend way). But I think that "extinguish" is very hard with OSS, so with financial models becoming less viable, open source might morph back somewhat. Or not; we shall see.

ptero··on All my new code will be closed-source from now on
> I think it’s rather that people need to eat.

They do and always did. But open source was originally not about that, but about building something cool and letting others build on that. And, crucially, about GPL preventing large companies from extinguishing your work "because copyright". I remember Bill Gates calling GPL a spreading virus that tech world has to fight.

Sometime along this path monetizing open source became a thing. Now it is apparently becoming less lucrative. OK. That's the nature of changes, but IMO it does not kill open source. It might eventually make it even better, as commercial open source has become too widespread and money corrupts. My 2c.

ptero··on Can I start using Wayland in 2026?
I don't know what "ready for prime time desktop use" means. I suspect it means different things for different people.

But with Linux being mostly hobbyist-friendly a number of folks have custom setups and do not want to be forced into the standardized mold for the sake of making it super smooth to transition from Windows.

I have such a setup (using FVWM with customized key bindings and virtual layout that I like, which cannot work under Wayland), so can I donate some money to Microsoft to keep Windows users less grumpy and not bringing yet another eternal September to Linux. I like my xorg, thank you very much :).

ptero··on Google is dead. Where do we go now?
> No idea how to fix the internet, maybe it's time to move to gopher or another protocol :-/

Fido and Usenet are still around. Kind-of. IMO google virtually killed that, too, when they started peddling google groups and did the classic embrace-extend-extinguish on the Usenet.

ptero··on As AI gobbles up chips, prices for devices may rise
Why? Work hard doesn't mean fully succeed.

HN policies and algorithms slow the slide, and keep it better than reddit, but the set of topics that allow one to take a minority opinion without downvoting keeps shrinking. At least compared to the time 10-15 years ago.

ptero··on As AI gobbles up chips, prices for devices may rise
That view is about 18 years old and HN was very different then.

As with any communication platform it risks turning into an echo chamber, and I am pretty sure that particular PG view has been rejected for many years (I think dang wrote on this more than once). HN works very hard to avoid becoming politicized and not discouraging minority views is a large part of that.

For example, I now seldom bother to write anything that I expect to rub the left coast folks the wrong way: I don't care about karma, but downvoted posts are effectively hidden. There is little point of writing things that few will see. It is not too bad at HN yet, but the acceptance of the downvote for disagreement is the strongest thing that pushes HN from discussions of curious individuals towards the blah-quality of "who gets more supporters" goals of the modern social media. My 2c.

ptero··on As AI gobbles up chips, prices for devices may rise
I don't know why you are getting downvoted. While I might agree or disagree with the argument, it is a clear, politely expressed view.

It is sad HN is sliding in the direction of folks being downvoted for opinions instead of the tone they use to express them :(

ptero··on Rob Pike goes nuclear over GenAI
> I still don't see the problem. You can criticize things you're part of.

Certainly. But this, IMO, is not the reason for the criticism in the comments. If Rob ranted about AI, about spam, slop, whatever, most of those criticizing his take would nod instead.

However, the one and only thing that Rob says in his post is "fuck you people who build datacenters, you rape the planet". And this coming from someone who worked at Google from 2004 to 2021 and instead could have picked any job anywhere. He knew full well what Google was doing; those youtube videos and ad machines were not hosted in a parallel universe.

I have no problem with someone working at Google on whatever with full knowledge that Google is pushing ads, hosting videos, working on next gen compute, LLM, AGI, whatever. I also have no problem with someone who rails against cloud compute, AI, etc. and fights it as a colossal waste or misallocation of resources or whatever. But not when one person does both. Just my 2c, not pushing my worldview on anyone else.
