also if you're going to "timebox" be very very generous. If you think it takes 30 minutes, give them 5 hours and say you're being generous.

I've known people who program things like jet engines and stuff that goes into space. They know their stuff, are super methodical and take their damn time to do it well.

Quality programming is a rarely practiced time consuming art and you'd be lucky if you have 10% of your workforce doing it. Heck, you'd be lucky if you have 1%. Those people save the ship.

I'm not one of them. When you meet them, they're like a different kind of human.

If you timebox them to 30 minutes, the people who write mission-critical quality code will fail to get it in on time and be filtered out.

These are the people who write those 10,000 word articles that appear on HN with carefully constructed schematics, equations, and code that you struggle to understand and bookmark to study later.

On the other hand, if you give people 5 hours, I assure you, the morons will still obviously be morons and you give the "True" Engineers who take their craft dead seriously a chance to shine.
I still remember being in awe of his paper on strange attractors - plotting the random number generators from various oses and languages in 3D space to discern patterns. That blew my mind at the time.

I always saw Pale Fire as somewhat of self-parody, which made me enjoy it more.

Seven years before Pale Fire came out, Nabokov was working on his translation of Eugene Onegin. Often, people argue that a translated novel should have no end/footnotes, because a "good translation" should read "naturally" to a reader. Nabokov disagreed, and wrote an article that included the phrase:

> "I want translations with copious footnotes, footnotes reaching up like skyscrapers to the top of this or that page so as to leave only the gleam of one textual line between commentary and eternity." [1]

Quite a fun image, and one he took somewhat seriously, as his endnote commentary for Onegin is more than twice as long as the translation itself! [2]

So, for me personally, I can't imagine a world where he didn't reflect on his own zeal here, and realize "I think there's a novel idea in here somewhere!"

> If you're a compiled language person and the build dir isn't in a tmpfs yet, give it a try. Faster than nvme

What are you compiling that’s actually faster in tmpfs?

A decade ago, people were surprised to discover that going from HDDs to SSDs didn’t impact compile times very much. The files are quickly cached in RAM anyway and the bulk of build time is CPU, not I/O.

Going from NVMe to tmpfs feels like an even smaller difference.
What information do thieves get from an erased iPhone and how did they contact the legitimate owner?

Does it say something like "locked and linked to sarah96@icloud.com" or can it display custom messages like "owned by sarah xyz, please call +43..."?

Could it possibly get you into situations where people can successfully threaten to physically harm you because your contact information doxxed you?

China is not a police state, they are a military state. The US is a police state. In China the local cops are generally far more hands off than an in the US. China is more top-down from the national level. In the US, local police are the typical mechanism for control.
Experience the Difference: Why Employers Are Relaxing Some Tenure Requirements
I 100% believe it's possible, but that's even more of a lottery than FAANG is which would negate his point :).

If you can get your foot in the door it's hard to beat FAANG comp on a risk-adjusted basis and they do actually employ quite a lot of SWEs, which I think is why it's such a focal point for tech jobs even though you can get similar comp in other situations.
how do you hibernate without swap? or do you just sleep?
On real machines I run with a super low swappiness of 1-5 or so, which effectively means it will always use RAM, basically until its too late. That way its difficult to accidentally get OOM killed, instead everything just slows way down when swap gets involved when RAM is full.
> apparently by writing to gl_FragDepth

If they do that, this disables early Z rejection performance optimization implemented in most GPUs. For some scenes, the performance cost of that can be huge. When rendering opaque objects in front-to-back order, early Z rejection sometimes saves many millions of pixel shader calls per frame.
What I'm seeing here is that Apple has a really shitty, poorly thought out design. To keep the phone useless to somebody who steals it, you have to keep it exposing your contact information so that people can threaten you.
To add to this, Chinese (and Japanese) Buddhist scholars' emphasis on retaining the original pronunciation of chants led them to hang on to the phonetically written Siddham script in which their masters had learned the scriptural texts in universities in India.
Consider for a moment replacing the NN with another person, who forms a model of the world that is very useful for prediction.

Now our lead experimenter asks this person "what will happen if the global average temperature increases by N degreesC?" and they get an answer.

Can we way that the lead experimenter has built a model? They have not, certainly not in the sense that they have any access to it. The person who replaced the NN may have (and indeed, probably has) built some sort of model, but that's a very different claim.

Explainability in NN/ML systems is a hot topic, and many people (not all!) would say that if the NN/ML system cannot explain why adjusting parameter X will cause changes in parameters A, M and T, then you have no access to anything that merits being called a model.

A consequence of this is that if the person who replaced the NN can explain themselves (e.g. answer the X -> A,M,T coupling), then even the experimenter can probably be said to "have a model". But if all that can be said is "I don't know and/or I can't explain, you just need to trust me that this coupling is real", then the claim that a model has been built is on unstable ground.

>I think at least half of all programmers got into it because of video games. They know it's desirable, so they can filter almost as hard as they want.

I had this whole pipeline where I figured

- okay, I don't have a master's degree

- there aren't any junior graphics roles.

- I'll work in industry for 4-5 years in whatever I can while working on rendering tech, and then get a graphics programmer job this way.

- I'll be in a cushy, in-demand, highly skilled, more protected part of industry from the layoff hustle and bustle. You don't throw away engine programmers at the blink of an eye

Alas, the industry shifted around in the blink of an eye. Most studios cared less about fundamental graphics for an in-house engine as they all just changed to unreal. I did in fact get an engine programmer role, but was still first on the chopping block for layoffs. The industry tighted the heck up over the last 18 months and my side hobby projects on github barely mattered as they wanted 5+ years of graphics experience. Back in the catch 22 I was trying to avoid with all this prep.

I wouldn't say my dreams are crashing down, but it sure did show me that nothing is truly safe, no matter how experience or well liked you are. Nor even how exploited; definitely had freinds completely underpaid that put 80+ hours into the company, and they still get cut the moment RTO is announced. You have the dream capitalist candidate but can't handle not seeing them 5 days a week with butt in seat.

>if you're currently between jobs right now, you could crank out a prototype of something and see where it takes you while job hunting.

That's the weird part. Prototypes are normally a great way to stand out. But the market here is sending all kinds of weird signals. I don't know what companies want anymore, clearly not a plain ol' hard worker.

I am still getting interviews, but they are cut short in the process or am simply ghosted. Some are botched tehnical interviews, others I have no clue. So more prototypes aren't necessarily solving my personal issues.
No matter what you think, best living mathematician is what other mathematicians say about him.

But I'll humor you. How would you prefer we say things?

- Highest IQ on record.

- One of only 3 people to score over 700 on the Math SAT before he was 8. He had the highest score of the three with 760.

- At ages 10, 11, and 12 he set the record for winning Bronze, Silver, and Gold respectively in the International Math Olympiad. After that he lost interest.

- PHD from Princeton at 21.

- Full professor at UCLA at 24. This is a record.

- He is a respected leader in at least a half-dozen areas of mathematics. He regularly publishes in many more. It is unusual for a mathematician to have significant publications in 2 areas.

- Wikipedia lists 28 major prizes for him. Excepting Australian of the Year in 2022, all are major mathematics prizes. No other mathematician comes close.

- Once you exclude junk journals, Tao publishes papers faster than any other mathematician. And his are all good.

- Tao's papers show up in the popular press more often than the next 3 mathematicians combined.

And so on.

At what point is there a better way to think about this than, "best live mathematician"?

(And yeah, until I began noticing Tao, I would have also thought that a silly way to think...)
I can only apologise.
Not that many, perhaps a bit surprisingly.
I am one of those people who wrote a production system controlling a million-dollar business fifteen years ago that is now controlling almost a billion-dollar production system today. The auditors are the main reason it is being changed, "single man risk" and "Obsolete software" (Delphi/MySQL) being the two highlights from the Deloits IT team.

The code is not brilliant, it is full of technical debt (as thats what happens when companies grow and change) but is still perfectly maintainable.

I have been watching the herculean effort of three different teams to replace this system, carving off the low hanging fruit to NetSuite and React/Java applications while repeatedly delaying the core system while they agree on standards to use.

I stick around as I am quite close to retirement now and the employees and the company are good to work with and don't deserve me to abandon them. At this point I genuinely want the projects to succeed so I can move on as there are many small companies still out there that I can make a difference in even with my age, single man risk and obsolete software.
Is it true that if you remove it from Find My iPhone then they are able to unlock it?

I didn’t see any warnings of this when I erased my phone after I recently lost it (and someone found it but decided to keep it)
Is Computing a Discipline in Crisis?
Nothing real. They cherry-pick for what they're trying to sell you this time - advent of 2nd core, +HT, E-cores, -HT, you-name-it-next-time. Without independent benchmark + additional interpretation for your particular workload you can safely ignore all their claims.
This happened to my sister. She got her phone stolen at a bar in Austin. They’ve tried to phish her multiple times and now it’s gotten to intimidation texts where they are threatening physical and sexual violence to her unless she unlocks the phone. She put it in lost mode right away and due to my assurance she knows she is safe but honestly it does make you kind of just want to unlock and get the nightmare over with.

She has tracked the iPhone via find my through a few us cities and finally it’s in China.

No. Thinner laptops often max out at 32 or even (!) 16GB. And defaults at incomprehensible 8GB.
Have you tried 10 kΩ for LED and FET pull down?

100 Ω sounds like way too much current for modern LEDs. I often end up using 100 kΩ especially for green LEDs. They are very visible under indoor lighting even with 1 MΩ and 3.3 V supply.

For pulling down FETs, you want something in the range of 10 kΩ. 10 MΩ sounds way too high, which makes your circuit sensitive to being touched or affected by moisture, especially if there are near by components connected to the power rail.

My digital electronics grab bag consist of 22 mΩ for sensing, 100 kΩ for battery voltage divider, 22 kΩ for one of the 3.3 V buck converter feedback dividers, 10 kΩ for everything else like I2C pulling.

OK thanks. I've filed an issue here: https://github.com/google/mesop/issues/345 if you could share with us a repro (the Mesop code you're running) on the issue, that would be helpful in debugging this.

If you take a look at the "table" example on the demo gallery: https://google.github.io/mesop/demo/ it shows how to use Pandas w/ Mesop, so I'm not sure what's going on.
Presumably the phone hasn't actually been wiped, or wasn't when the crooks first got the phone number.

Smart phones generally let you add an Emergency Contact number that anyone can use the phone to call/text without entering a password, in order to facilitate an honest person returning the phone or someone contacting your family if you are found incapacitated.
Technically, you're correct.

I just don't like being threatened on their download page.
> coke(!) in the South

Haha. Can confirm. I am from Arkansas, and before they passed on, my grandparents usually kept a variety of soda in the house for us grandkids (they never drank it, they of course loved their coffee).

it didn't matter what kind of soda was actually in the fridge, every soda was a coke. my grandma would grab a dr. pepper or a pepsi and say "ya'll want a coke?"

good times. miss those two.
This seems like a lot of work for one (or two, once it got to China) people repeatedly trying to get into the phone. I wonder if this is like debt collection agencies where the stolen phones get repeatedly fenced at a steadily decreasing value, and each new owner has a go at sending out these unlock copypastes until it's clear that it's only value is in being scrapped.
I think they must be referring something in an unstable-series kernel. I don't remember anything like that, but I only ever used the stable kernels. (Back then, there were separate stable (2.2.x, 2.4.x) and unstable (2.3.x, 2.5.x) branches. "Linus forced a swap rewrite" sounds like an unstable branch thing.)

I always heard that the "2x RAM" thing came from some primordial BSD release.
manipulate and influence are similar. So why are people offended?

Influencers get paid for influencing/manipulating people. You now got the concept. If that upsets you, you are kind of slow.
Misconception: Police are trained to investigate and solve crime

Reality: Police absolutely hate doing the "boring" parts of their jobs. Property crime clearance rate is an abysmal ~10% and everyone knows a handful of people who reported a theft, large or otherwise, and got nothing but a police report.

Meanwhile they had plenty of time to come to our local supermarket and harass a 6 year old that tried to pocket a candybar. They took him into the security camera room and hassled this kid for several hours, zero parents involved.

The American police do not feel required to do their damn jobs, unless it involves physical activity or a gun. The boring stuff, like submitting hundreds of stored rape kits to labs to literally catch rapists, doesn't get done, ever.

And THIS is why i support parts pairing. 3 years ago, the LCD and battery could be resold making this worth it. This year - nope. I dream of a world where even the little screws that hold my iPhone together are parts-paired so stealing it costs more in effort than the possible $ recovered from it!
start using very high entropy passwords which contain just about all printable ascii characters, excluding whitespace.

If a computer cant guess it, it won't crack the hash, either.

Use a password manager and make those suckers 20-40 characters.

Use a master key that is just a super long phrase interleaved with special characters. Easy to remember. Like titles of books you like, plus authors, plus something only you know. Stuff like that.

I use a version of KeePass, with the actual file synced via syncthing to all devices plus a cloud.
I downloaded the app but only saw a few stories to browse. No search or tags. I wasn't interested in any of the stories so I closed the app.

Have you considered writing a few dozen comics yourselves to seed the experience? Authors won't want to publish if there are no readers, and readers won't want to brows if there's barely any content.

I assume they just eject the SIM card tray and get your phone number from the SIM by simply putting it into another phone.
If you ever get involved in hiring people, you realise that there are people slipping through the cracks. I've come across freelancers or underemployed people making a fraction of what their skills should be earning them, and it seems totally arbitrary that they're in such a position. It's lucky - for both sides - when this match happens.

An efficient system would make this integration easy, but I agree, for a lot of people to get anywhere, they have to "insert themselves".

Simultaneously, it's actually quite easy to be oblivious to this -- if you go to school, get good grades, get a graduate job, and do well enough at your job (but remain a normal employee), you'll never have the opportunity to have this realisation.
By default you can set the "lost mode" message. many people put their contact info into it, in case someone wants to be helpful. This is how these scammers get this info. There is no other way to get the icloud contact info from a phone with a PIN/password.

Yes, as long as it is in your account, nobody can activate it. When you remove it, it can be activated by someone.
> SHA-256 is NOT good for passwords

Can you define SHA-256? And not good? Using it with PBKDF2/bcrypt/etc. seems to be widely accepted, but we don't know if you were referring to a single unsalted round of SHA-256 or what. Also by "not good" do you mean "easy to reverse the hash itself" or "easy to bruteforce the resulting password"? I think these questions make a big difference, e.g. you could have the most complex hashing algorithm on Earth, but if they're bruteforcing a three digit password, it doesn't matter.

(something something bitcoin uses sha2)
Guess you have never used https://snapcraft.io/, https://flatpak.org/, or https://appimage.org/ because all of these do exactly that. Snap apps are straight linux containers and the others root like chroot jails I believe still.

Or even go take a look at Nix/NixOS and how they pull it off in another way. They have hermetic isolation down to a science.

Or heck, just look at what Android does, running each app under its own uid/gid, sandboxing 3rd party code, and keeping each app from reading and writing outside their little jails. Can't pollute a user directory or even write to /tmp if your user can't even enumerate it.

Hell, even built a whole sandboxing capability-based security model inside of Fuchsia at Google, which I worked on for 5+ years.

I've been building OSs for 20+ years, between Fuchsia and Android at Google and mobile/embedded products at Texas Instruments, so I hope I know what I'm talking about.
In the case that I lost my phone, though, instead of it being stolen, I really might want my contact info displayed on the lock screen so someone who finds it can get it back to me.

Yes, I know, in many anti-social places in the world (like most US cities), it's much more likely that the phone was stolen, or that even in the lost-phone case, the person who finds it will be shitty and not try to return it. But in many (most?) other places people are generally honest and will try to return something that's lost.

Then again, if you know that it was stolen, you should be able to keep the thief from getting your contact info.
You can get an interesting sampler by picking up a recent Best American Poetry and looking at the bios in the back. Some are academics, but there are also doctors, lawyers, accountants, and so forth. I had a long-running project which attempted to rank graduate creative writing programs by their alumni’s appearances in the prize anthologies and one interesting byproduct was collecting a lot of author bios. I think the bios for those who I could confirm had no graduate creative writing degree or could not find evidence of one were the most interesting.
