> It sounds to me like you've never encountered actual challenging engineering problems

I worked on low level machine learning infrastructure and distributed algorithms at Google. I know pretty well what challenging engineering problems looks like.

> No I don't. AT ALL.

You don't think your inability to visualize computation affect your ability to come up with solutions to problems at all?

Edit:

> Your sorting algorithm will mean jackshit when you spend all your time doing I/O reading files in and out of memory for example. Your super cool distributed algorithm means nothing if you don't understand CPU P-States(I guess that's irrelevant nowadays) or NUMA and didn't setup the machine properly.

I understand those things well, it isn't hard to learn, we run benchmarks using proper prod setups and see what works faster and we know about CPU caches, memory overhead, file reading speed etc. The only difference is that I am fluent in algorithms and you aren't. I'm not sure why you'd think that I wouldn't know those thinks just because I know algorithms, it takes like a few months to master algorithms, there is still plenty of time to learn the other things.
I assume by 'depreciation' you mean prices fall down or don't go up?

Yea, why is that a bad thing? If house prices keep going up it just makes it impossible for young people to start families. Why would anyone want that?

Treating homes as investment kills the social fabric.

That said, houses in Tokyo are quite expensive. Try looking online (like on suumo or sumaiti or lifull homes websites) and you will see that a house for a family with 2 kids costs upwards of half a million dollars. Which I think is insane.

Houses on the country side are much cheaper (half that price or less).
What I do know is that burning fossil fuel to move around on a daily basis is not great for the environment, that is a fact. My opinion is to reserve the fossil fuel burning to things that can't yet be easily converted.
Your car has a good engine (mostly because it's regulated). Your lawnmower has the cheapest possible engine that will spin a blade.

The cheap two cycle engine does exhaust and injection in the same cycle. Inevitably a large fraction of the injected fuel is also exhausted. How that tired back to green house gases I'm not totally sure, but it's certainly very bad for your lung health to breathe it!
Would it be that bad if it were a persistent check that happened on boot? All you'd need to do to validate the hardware in your phone is reboot it and it would barely have any impact during normal operation.
>Have you even seen how large the properties are in Woodside, Atherton, Portola Valley, Palo Alto, and Cupertino?

This sounds like a problem for the rich that (just as you described) they can pay to make go away.
California legislators do not care about the practical details, as long as their abstractions become ever more pure.
Just because something is better (by various metrics) doesn't mean it will have "won the market". That's never been how things have worked, "the market" is far from perfect.
No: you ban the *use* rather than the *sale*
It uses magnetic field to spin the rotor, so it can be completely silent. A gas engine, on the other hand, has to use a bunch of mechanical parts and belts, in addition to cylinders burning fuel, and those are noisy.
I wrote Cloudfront but meant Cloudflare. My bad.

I have a script that updates the dns record on a free tier plan with Cloudflare, and since traffic passes through them I can open my residential network to only ports 80 and 443 from their ip4/6 addresses.
I think you're right. Googling around most of the sound is generated by the air movement, but ICE blowers seem to be ~1-3 decibels louder, but may be a bit more powerful.
they are unnecessary excess.

guess what, ya don't need a goddamned cut grass lawn.

we are putting in ponds and forest gardens starting next year. no more yard.

downvote away, but these are exactly the kind of austerity measures required to get used to (and MUCH MUCH more) in order to realistically get things on track.
Are they banning solely 2-stroke engines though? It sounds like they are banning everything. Many of these items are available in 4-stroke models.
Hi there! I'm in the process of adding the final touches to the sample review. It should be there soon.
Not really no, but if the infrastructure is in place it's easier to switch the source of energy from one to the other, wind, solar, hydro and nuclear is transmitted through the same powerlines as gas, coal and any other kind of generated electricity.
I wonder how many people it takes to enable the production of one IC. From absolute raw materials to device ready to place into a product. Machines with parts made using other machines and so on. Including the parts and processes and people's experience operating across all of it.

It would be interesting to see this whole thing mapped out. It seems to me that this might be helpful in understanding which parts of this ecosystem might be low hanging fruit.
> The point of a coding interview is to eliminate, as fast as possible, people who simply can't code.

I sincerely don’t believe this is true or that there’s any supporting evidence for it besides people repeating it. The point is to eliminate employment discrimination claims for large companies and this is what baseline they established to support the claim.

The point for everyone else is: we have too much to do, figuring out how to interview effectively and fairly is too much more work. Let’s use what everyone else uses.
No, primary sources are not banned on Wikipedia.

The kinds of things I offered corrections on were simple and sourced off public filings. Like the relationship of the company with another -- our company bought another, but wikipedia claimed the other company bought ours. Another obvious mistake was the picture of our building. They put a picture of the building next door. There were a number of really egregious mistakes that I tried to correct, but I got a no-comment reversion of almost all of them.

And in case you were wondering, at no time did I identify myself as an employee (and I was just a software guy anyway, not part of the marketing group), nor did they suggest that they knew I was.
You say groping is quite widespread. I am not going to argue because there is surely some improvement to be made there.

But context is important. Daily ridership of all Tokyo rail lines is around 40 million. So, assume reported groping cases are around twenty per day (this is a ballpark estimate I don't know the actual number). And say only one in fifty of actual cases are reported, that gives us 1000 actual gropings per day. So we have around 0.00025% of rides affected.

Again, it's not nothing and it should be better, but I wouldn't want people to get the impression that there is a high statistical likelihood of being groped when riding the rails in Tokyo.
PSA: Latest macOS on Apple Silicon just lets you copy anything from images so I assume works on pdf's too.
Is leaf blowing the original bullshit job? Just embrace the leafs.
Thanks so much! I'll keep those in mind as I move forward. Did things ever pick up for you? Or did you move on to other projects?
Sometimes I suspect the obsession with CO2 is encouraged by the most polluting of industries.
This is so ham-fisted and out of touch and politically stupid. The way to achieve things like this is to finance superior alternatives so that the undesired technology is naturally, organically abandoned
Why use malloc() when mmap() does the job
80% bounce isn't great, but it's also not too far from normal.

I would say that it is unclear from the sliding text on the hero what the actual value proposition is. Are you helping employees directly? Are you saving the business money? Are you helping them comply with employment laws?

It seems like you're targeting employers who want to comply with NOM-035 (whatever that is). In that case, just one message at the top (sliding text is too hard to read and digest) would work better.

For instance, "Employers: Comply with NOM-035 and reduce employee churn by 30%" would be a good top level message. The rest of the page answers "how do you do that?", "how much does it cost?", "who else uses you?", "how hard is it to implement?".
I have a laptop that has secure boot and a tpm 2 chip, but microsofts tool said the cpu was too weedy to run windows 11.

Switching to the dev track in windows update seemed to change their mind and it updated to 11 anyway.

I would try that first if you are just stuck on the cpu requirement.
Yeah it's easy for them to draft up laws from their ivory towers
Thanks for your well wishes! Much appreciated.
When was the book published?

I've seen older footages of Tokyo (1960s) where the streets were pretty chaotic and dirty. Also Miyazaki described how the rivers used to be very polluted, which inspired the bath scene in Spirited Away. Not sure at what point it changed.

Also remember Americans telling me Seoul being dirty in the 80s, but is generally cleaner than western cities these days.
Isn't the issue here that the security chip is on the screen vs the motherboard?

Given a screen is probably 100x more likely to break this is consumer hostile engineering.
> "As well intentioned as this law change is it will only make a hard job even harder. Battery cost, battery swaps and reparability, battery theft"

Yes, absolutely.

If we have any hope of reducing our impact on the planet, some parts of our lives are going to get less convenient / more expensive / harder / more time consuming. At least in the short term, switching away from burning dinosaur oil will be a little painful.

Our grandchildren will appreciate that we tried, rather than sitting around saying "it's too hard!"
Do you mean they did and people overwhelmingly chose repairable, so they invented a narrative to support the answer they wanted?

I don't know anyone that would forgo having a repairable phone for the tiny bit of extra security it gets them.
Why is there such demand for the ICE ones? The electric ones are cheaper (new at least) and cost a fraction of the operating and maintenance cost. Plus you can now have good reason to ask for outlet/power access at job sites so you don't even pay that cost anymore.

This probably doesn't effect used /existing stock either.
Regardless of the history of that term, the underlying concept is not unique to the US and was not invented by the auto lobby.
My understanding is that the repair shop has to provide full customer details including address, phone number, and the like to Apple for any repairs done.
Most such courses don't give a typical Leetcode problem in an exam with a 30-35 minute time limit, replete with continuous interruptions from the examiner.

It's a lot easier for me to do a Leetcode problem if I can explore and experiment a bit without having to verbalize my whole thought process.

Also, this is nothing unique to SW. I come from an engineering background, and we had to do calculus in almost every engineering course. Yet I'm sure within 12 months of graduation, most of my fellow grads would struggle with most calculus problems. I was once criticized by my peers for asking a basic calculus question while conducting an engineering interview.[1]

Just as with algorithms, you usually don't need calculus on the job. Looking at most of my SW development career, beyond the very basics (e.g. dictionary lookup is O(1) in Python), I probably needed algorithm knowledge on average once a year. And since almost none of my peers in most of the jobs have that knowledge:

1. Knowing it doesn't put me at an advantage within the company. It's a blind spot for everyone. Unless I happen to solve a serious business problem with that knowledge, which is very rarely the case (and likely why most people forget this knowledge).

2. My not knowing it won't put me at a disadvantage when it comes to career growth in the company.

This is the reality for most non-FAANG SW jobs. I suppose the one benefit of all these Leetcode interviews is that a lot more people have an incentive to review/learn this material.[2]

[1] Analogously, I was once criticized for being too tough when I asked a candidate to write a factorial function for a SW job.

[2] Although perhaps not really. Last week I interviewed a candidate who knew the theory really well - he understood complexity really well and seemed to understand data structures quite well too. But he couldn't write a basic function to split a string of numbers that were comma delimited, and return it as a list of integers. In both the languages he claimed proficiency in, there is a standard function to split a string, and not only didn't he know the functions, he had know idea of the concept. A classic example of textbook knowledge vs experience (of which he had 3-4 years).
(Perfect pitch here, jazz pianist.) Yes, what you say sounds right. Although I don't remember a time before I knew lots of things about minor 3rds, so I don't know what that's like, or which came first. I don't know if there are many people with perfect pitch and without childhood music training/practice—I don't think so.

I also have no idea why it would help with brain recovery.
But you can use them. And even if they banned use the scale is so small and unimportant compared to what zoning laws could change. It’s theatre.
I'm a heavy DeWalt user and I'm already a little salty sometimes about how much they charge for their batteries. If they change up the standard again so I need adapters or new tools, I'm going to switch manufacturers altogether. So far I like their stuff well enough, thankfully I haven't run into any problems with new batteries not working out of the box yet. Knock on wood
I expect them to not explicitly endorse bypassing security measures they deemed appropriate to ship. But, you didn’t need to ask that, I thought it was quite clear that was my expectation.
Love micro and use it frequently in my work. Simple, easy to configure, and sensible keybindings.
Security updates past 2025.

TBF, it's not like that's going to be nearly as much of an issue in 2025 when that Skylake CPU hits 10 years old.

Additionally, you can still run Windows 11 on Skylake, you just have to disable a few things.

I'm sure there will be a Windows Update patcher if MS does the same thing they did to prevent Server 2012 from updating on Kaby Lake and newer CPUs.

I think is very reasonable from MS's position to officially sunset those CPUs while not trying too hard to prevent them from running.
Raising children is different from anything you do in the workplace. "Professional" abilities aren't the key metrics for this responsibility. The best "boost" I'm aware of for being good at the job is being raised by good loving parents and thus having a good model to then emulate when it becomes your turn. Sometimes people can find good models elsewhere, but the number of places one can do that today is pretty small — media and movies certainly don't.

From my research, the sociological numbers bear this out, good homes make better well-adjusted successful and able children who generally go on to make another generation of well-adjusted and successful children.

Broken families, single parents homes, have lower success rates.

If you want to create an environment where our most valuable resource is given the best shot, then we should be teaching about marriage, man+woman partnership, fidelity and faithfulness. We don't have any known better models for raising them — and it isn't even close.
Electric lawnmowers and leafblowers have come such a long way. My electric lawnmower weighs next to nothing, needs virtually no maintenance, and it is only about as loud as a box fan. I get 2-3 mows out of it on a single charge, and the upfront cost was on par with (if not a little less than) an ICE lawnmower. There is no reason to not move aggressively in this direction.

That’s a good idea, and would probably help fill out the calendar a bit more!
Did he deserve it?
The quietest reviewed blower in that article has about 40% the power of an Echo 755 gas blower (similar volume flow at 62% the speed; power is quadratic with speed and linear with volume).

It is not at all surprising that it’s much quieter as a result of putting ~40% of the energy into the stream of air.
a more esoteric version is to boot to the windows 11 iso and use the command prompt to bypass the install wizard and manually install the system through DISM and related friends.
A lot of what makes software snappy on phones is fixed function hardware, ie hardware acceleration. The hardware gets more specialized and the software gets heavier.
The Flynn effect is examined over decades not centuries. People today test better than people 40 years ago did on the same test. This can be measured in real time when the average person in an african country goes from malnourished to nourished - the average intelligence increases.

IQ is not the only thing that improves. Different types of memory have improved over the same time periods.

Even from a theoretical perspective it doesn’t make sense that people who complete manual farm labor their entire life would be as intelligent as someone today who is educated for almost 2 decades.
They limit the hours, which is usually ignored. Limiting the days might be a much more effective method.
Those of us burning the fossil fuels don’t have to clean it up

Glad to hear that things worked out alright. I've never heard someone use "f*k you money" before. I'm definitely hanging on to that one.

Ideally with decentralized identity, you use a separate identifier with every relationship. Otherwise you have created the ultimate super cookie.
The content is very interesting but those scroll-triggered animations are obnoxious. For marketing a product or something, okay - but as graphics interrupting the flow of an article, no thanks - especially with this aggressive military aesthetic they’ve got going on. Unfortunately they seem to be quite in vogue at the moment.
> It talks a lot about the lack of zoning

Tokyo is very much regulated based on nuisance level. Walkability is not a fluke. Nurturing the social fabric takes planning.

Same for avoiding food deserts, obnoxious shopping malls, or soul-crushing sprawls. It's all by design.

> The downside is that Japan's lack of planning makes it kind of ugly and boring.

Huh??
so, funny enough i always thought this as well. i have since stopped condescending to others about what they should or shouldn’t like.
I think is the case that all the non speculative assets in producción (machines and labor(industrial employes)) are simply not worth, because is not individual problem the supply disruption, The investment and all that free money is simple put in speculative assets
We appear to be mostly in agreement, and specifially on the point that in practice archeologists probably necessarily do the exact economic analysis I'm advocating.

I suspect the friction point may be about whether the idea or meaning of a ritual is an encompassing abstraction for general social shared experience vs. a specific sub-category of experiences that I am saying requires sympathetic magic. My view ignores whether there are rituals that are not sympathetic magic, and I'd posit there aren't, and that ones that don't have it are are just habits. However, the exceptions others point out should show the limits to that heuristic as well.

Very much agree some science has been ritualized, which imo de-sciences it, and to me this discussion of our relationship to meaning is a really important idea at the root of this question. It's related to what we deal with as hackers, which is whether our abstractions are meaningful and powerful tools for illuminating complexity, or just a layer of obfuscating jargon.

A criticism I think we might agree on is crappy social science and theory papers are like a "Chinese Room," where the authors have taken opinions, transliterated them into something that gets published using some stats and p-hacking and formal methods, but it's as though they have never had "real" understanding of the subject or material, and the crossover is that this chinese room meets sympathetic magic pattern resembles the category of ritual I was describing.

It's helpful to refine this stuff, thank you.
Why not? It’s a grave and they robbed it.

Suggesting archeologists on the other hand are robbing the grave implies they both don’t own it and the archeologists are taking ownership of whatever is removed. The first might apply but the second doesn’t.
I've used extension cord based equipment in several countries (places with large lawns and places with small lawns). You do have to keep track of the cord at all times (lest you mow the cord in two) , but it's not a huge bother.
>What is produced by the forest is consumed by the forest. We don't want a closed system, we want a system we can tap into and feed our million-people cities.

I'm increasingly of the mind that humans viewing themselves as apart from the biosphere, rather than an element within it, is a flawed mindset wholly responsible for our current predicament. It seems unlikely that digging ourselves deeper into that hole will bring about a positive outcome for humankind or the natural world on which we have always depended.
To your point about an outlet - what about jobs where this would require a couple hundred feet of line?

My landscaper recently told me the gas ones are still far more effective. I assume he would know? They go from site to site every day, I’m guessing they don’t have time to charge and want the best tool for their job as all of us do.
The gas ones run all day on a single fillup and no need to charge batteries.

You’re talking changing a hour job into potentially longer from battery swaps and asking for plugs, etc.

And in general the gas ones are cheaper but that is getting closer.
I worked in Hong Kong as a missionary from 1988 to 1990, and part of that time was spent in Kowloon City (a region of Hong Kong which contained the Kowloon Walled City). The Kowloon Walled City largely consisted of a large block of walk-up highrises so close to one another than there was no ventilation. The way you got into it was through what I'd describe as rat tunnels snaking underneath the buildings. The actual living environment was horrific. We'd often try to find out how to get up to the roof of the locally tallest building and watch the airplanes fly overhead and land at nearby Kai Tak airport. They were so close you could probably hit them with a rock.

One particularly vivid memory I have is of the illegal dental offices which ringed the outside street level. These shops all had skulls in the windows with teeth showing their handiwork.

I recently went back to visit the place -- the city had been torn down, revealing the original historic garrison at the center, and it's now a lovely park. When I was there the garrison was kid of like a little quad in the middle of the City where nobody dared build: many people thought it was originally a temple (it wasn't).
