injb··on Why homes often feel warmer than the thermostat suggests – what to do about it
I had the same issue for years in the Midwestern US. I wasted a lot of money on the little 1 galon warm and cold mist humidifiers.

You need the type that uses multiple paper wicks (they look like air filters). I have one that uses 4 of these and has 2 big fans. It can burn through 4 gallons a day. It's not quiet but it does work.

And as a bonus you can use tap water without having to worry about limescale (it'll stay in the paper wicks which are replaceable anyway)

injb··on Math for kids outside of the Calculus Sequence
This is a really good idea. I'd emphasize combinatorics and probability because these are actually the most useful.

But I would add group theory too! For me this was the first time I realized that mathematics doesn't have to be all about numbers or geometry. Although, come to think of it, add geometry to the list too.

injb··on Ironically, Zoom tells employees to return to office for work
Why? Why would an employer care about studies? They have either seen a drop in productivity or they haven't. They couldn't care less about what other employers are experiencing.
injb··on Scientists of Chinese descent leaving the US at an accelerating pace
>>> It is in every way a demeaning and torturous process. You get treated like second class human beings and are forced to fight and prove you deserve something others were simply born with

Did you have a very bad experience with US immigration? I've been dealing with it for a couple of decades, from non immigrant visas to GC and while its definitely a pain in the ass, it hasn't been anything like that^.

There's a lot of waiting, and a lot of uncertainty and anxiety but it was never personal for me or anyone I know.

injb··on Major government tech contractors use vendor-lock to drive revenue: study
I worked for a company that did state gov contracts. We probably built legislative publishing stuff for more US states than any other company in recent years.

We never ever locked anyone in, not even little bit. We bult everything on open standards (odt and later docx), django etc.

A typical cycle was they would hire us to do joint development for 1-2 years, then a juicy support contract for another 1-2 years, then they gave us the boot.

My feeling after doing that many times is there's no money in it really. Government clients are impossible to work with. They have utterly perverse incentives that defy any rational mind and they don't pay if they can get away with it.

injb··on I earned a million dollars as a mediocre, 70-year-old programmer
Lol if you were pointing out that I basically called myself a brilliant programmer, it was an accident I swear!
injb··on Sinn Féin publishes Bill to ban sex for rent
True. This generalizes - when there isn't enough of something, only more of it can fix the problem. Rules for regulating what we have might be some small help, but not much, and they would become totally redundant if we had enough of the thing in question.
injb··on I earned a million dollars as a mediocre, 70-year-old programmer
>>> Why do brilliant programmers make bad teachers? It’s called the curse of knowledge. Some of the smartest authors in the business are clueless about a beginner’s needs.

So true. I'm usually good at teaching and explaining things but after learning software development gradually over the course of my whole life, I have no idea what its' like for beginners, especially nowadays that stacks have so many layers.

injb··on Ask HN: Growing Users in SaaS Business
I don't have any advice to offer, but I'll give you my passing impression: it strikes me as the epitome of "ML as a solution looking for a problem". The reason people aren't getting excited is because most people are excited by outcomes, not by tools and technologies. I doubt that many people in marketing or real estate can visualize what ML could possibly do for them. That's where you need to focus imo - the killer application that no one (in some specific domain) can do without.
injb··on What Does IQ Measure? [video]
I don't see why this should prevent it from being considered "scientific". These things limit how precise it can be but that doesn't really matter much. A few points don't matter.

Do the test when you have whatever is a normal amount of caffeine for you and after a normal nights sleep.

injb··on You need team of about 500 professional job-hopping money-driven 9-5 engineers
Unless he's talking about the same project in both cases, it's a meaningless comparison. Can you take that OSS dev and put them in the consulting firm and have them replace everyone else in terms of productivity? I worked in an enterprise software company with a couple of people who founded some very well known and widely adopted OSS components, and while they were great by all accounts, they weren't 500x developers, or indeed even 10x. The difference is that with the OSS projects, they could do whatever they liked.
injb··on US universities need to stop elitist discrimination that Europe abandoned
You don't understand that "leading to more money" isn't the same thing as "gatekeeping access to more money"?

There is more than one way to make more money.

injb··on US universities need to stop elitist discrimination that Europe abandoned
But this doesn't constitute gating of social mobility. The US has only one gatekeeper of social mobility: money. And elite universities are not gatekeepers of money.
injb··on US universities need to stop elitist discrimination that Europe abandoned
>>> For America to regain its social mobility, its top universities need to follow the data and stop practicing the kind of elitist discrimination that much of Europe has abandoned.

This is the only part I can read before the paywall kicks in. But I wonder why they think that top universities are the drivers of social mobility.

injb··on the West can no longer make war
I sometimes wonder if the real issue is that Taiwan represents the incompleteness of the revolution. It's like if the Romanovs had escaped Russia and lived in exile. It would have been a constant thorn in the side of the soviet government. It's not just about the territory, it's about erasing the past.

With that said, no matter how ideologically important it is to China, I don't see how they're in a position to fight a protracted conflict. They would need it to be a sudden move, a _fait accompli_ by the time the west gets up in the morning. The fact is that China is a massive importer of food and other resources by sea and the US navy can blockade anything it wants.

injb··on How fast should you accelerate your kid in math?
>>> they don't really exist. They're anomalies in measurement methodology, likely to be temporally localized as well. Because everyone knows some "gifted" child, but no one can point to the unique and amazing accomplishments of them as adults

That's a shocking claim to make. Feynman, Von Neumann, Turing, Einstein, Gauss...I think I could go on all day naming people whose contribution to society was outrageously disproportionate and who were all stereotypical "gifted children".

Of course they exist. You wouldn't be having this conversation on a computer on the Internet if they didn't.

injb··on How fast should you accelerate your kid in math?
+1 in fact it's hard to think of a statement that's less in need of a citation.
injb··on Ask HN: Is the market bad, or am I having the worst luck job hunting?
I'm not an expert but your implicit premise that it's OK for a cv or resume to have multiple pages surprises me.

One page! Put the most recent relevant stuff on one page and send that. I don't agree with the idea that it's OK to include more info because people don't have to read it. They do have to read it because it might contain a red flag.

Every word you type is making work for someone, and if it's not then why write it?

injb··on Why no Roman industrial revolution?
Well said. Ever since I started reading Taleb and Harari I have become really skeptical of anything that sounds like a story.

If your theory of some historical development sounds like a nice complete satisfying story with no weird loose ends then it's probably not what happened.

injb··on Ask HN: Stay at a company just for the green card?
I'd stay unless I had other GC options (like exceptional qualifications or achievements that would get you into a high priority category). Another factor is how much time is invested in the GC application so far?
injb··on I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA
OK I edited and removed the first sentence. Apologies if I sounded condescending.
injb··on I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA
Thanks. I'm asking how it would help you to become an immigrant (the original question).
injb··on I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA
Could you elaborate on how an E2 founder could get to become an immigrant?
injb··on The First Smart Gun Is Finally Coming to Market. Will Anyone Buy It?
Many people keep a gun around because they have the mindset of preparedness for very unlikely events. As a result of that mindset, the prospect of the gun not working in the moment of truth is a very real concern.

For example, many people will not own or carry a gun with a manual safety because of the anecdotal cases of people forgetting to disengage the safety and losing the fight as a result. I have heard police express this view, after they personally investigated such cases. The notion of "fewer things that can go wrong" has always been a major selling point for handguns - previously, it was revolvers and nowadays it's Glocks and their myriad of clones.

Therefore, there will be many people who will not adopt this willingly until they see the police or military adopt it. They will feel that there's just no good reason to take the risk.

injb··on Bootstrapping to €600k MRR and getting killed by Shopify: Checkout X
I'm not familiar with Shopify but this was my first thought on what he should have been doing with the money. Even if he didn't actually achieve it, if he had made substantial headway in that direction then Shopify would have been well advised to buy him out rather then kill him and risk a major new competitor.

Still it sounds like a heroic tale and I this this guy is going to end up landing on his feet.

injb··on Visa-free travel to Europe for U.S. citizens to end in 2024,requiring ETIAS form
The title is a lie and the content of the article is hyberbolic. When the new requirement comes in it'll be the same as it is now for people who visit the US visa-free. The US has had this for years and Canada also has it for non-US citizens.
injb··on Tesla to license Full Self-Driving stack to other automakers, says Musk
>>> Not optimistic, just lies.

Why do you say that?

injb··on What’s the best blog post of all time on the internet?
>>> The key to the biggest number contest is not swift penmanship, but rather a potent paradigm for concisely capturing the gargantuan.

What a sentence!

injb··on Cut a circular hole of radius 1 in paper. How big a disc will pass through?
I don't get it. How would folding the paper help? Folding the disc would help but then the thickness of the paper would matter, which we haven't been told.
injb··on Why was the F-117 retired so quickly?
Why is leaking fuel brilliant?
