> But I suspect a huge part of it is visiting Europe or Asia as a tourist and enjoying being without a car.

I live in Dublin. I'd rank it as pretty middling in transport by European standards. We have a decent bus network, commuter rail to the suburbs, trams that are frequent but overcrowded at rush hour, and intercity trains to the other cities in the country.

I've been here nearly a decade and have no great rush to buy a car. And there's still obvious improvement to be made. The red line needs a relief line unless work from home makes the expanse of new offices at the end of the line mostly empty, cycling lane coverage is spotty and often conflicting with buses or parking, and bike parking is lacking.
Yeah. Its weird but I find doing this makes people respect you more.

If you ask dumb questions, the person speaking (if they’re any good) will start looking to you to figure out if they’re pitching their language correctly. The other people in the room who didn’t understand will be relieved and quietly thankful of you because they didn’t have to be the ones to ask. And people who understood already are usually way more chill about this sort of thing than you would expect. Especially if you give them the opportunity to explain something in front of everyone. And then thank them for doing so.

I don’t think I fully understand why, but asking dumb questions is often a subtle act of leadership.

With the free hobbyist version at least, yes that's correct. You can export the files however.
>So this story does not come off as an example of "I don't mind being seen as stupid", it comes off as a very strong example of "I'm holier than you"-attitude which is the entire opposite than the article author's is trying to make.

Exactly my thoughts.

Even the way the story is told to the reader with: "which I had a good reason to want at the time", has the same sentiment towards us.

"My reasoning is even above explaining to you, my reader."

When I was younger, I often met people who seemed kind of dim to me, at first, and later found the majority of them to be orders of magnitude brighter than me.
It was not hard to connect the dots, the reason they were so much brighter was (in part) exactly because of what made them initially seem dim.. They asked questions, honestly. Not the showoff kind of question you ask to show how much you know, but real, honest questions that not only showed how little they knew, but importantly, allowed them to actually learn and understand, rather than just nod and not get it.

My intuition has changed from this, I find it that most times, when someone shows genuine interest and asks honest, revealing questions about some new topic, they often excel at many other things (and will likely on the new topic as well).

I'm adapting this myself, being honest, asking honestly, and sometimes looking really stupid (because, in that context, I am!), and I appreciate greatly both the wealth of information that allows me to access, and that almost anybody worth their salt recognizes this trait as well.

Failing an interview due to looking stupid is probably a blessing in disguise, you don't want to be hired by people who can't see this, and you don't want to work next to people who's just pretending to understand, not learning because they can't afford to look stupid when they are (and thus stay stupid, and be much more inclined to try to pass blame to someone else, like you, who look stupid).
If you’re new to signal processing, then just remember that the basic algorithm of spectral analysis is the DFT and the FFT is just a clever way to compute it by skipping all the redundant operations.

The DFT is trivial.

Assuming you mean 1b have had at least 1 dose, I don't think that's true. If 1b doses have been given, and ~300m people have had 2 doses (i.e. consumed 600m doses), that surely means ~400m doses were left. So a total of 700m people have had one or more doses.

Saying a 10 year old laptop is 2x or 4x slower than a new laptop is just a tiny part of the big picture.

I would say that for a light laptop user, the main reasons to upgrade are:

- displays: make a big difference for watching youtube, reading, etc. You can't really compare a 120 Hz XDR retina display with a 10 year old display.

- webcam: makes a big difference when video conferencing with family, etc.

- battery life: makes a big difference if you are on the go a lot. My 10 year old laptop had new something like 4 hours battery life. Any new laptop has more than 15h, some over 20h.

- fanless: silent laptops that don't overheat are nice, nicer to have on your lap, etc.

- accelerators: some zoom and teams backgrounds use AI a lot, and perform very poorly on old laptops without AI accelerators. Same for webcams.

If you talk about perf, that's obviously workload dependent, but having 4x more cores, that are 2-4x faster each, can make a big difference. I/O, encryption, etc. has improved quite a bit, which can make a difference if you deal with big files.

Still, you can get most of this new stuff for 1000$ in a macbook air with M1. Seems like a no brainer for light users that _need_ or _want_ to upgrade. If you don't want to upgrade, that's ok, but saying that you are only missing 2x better performance is misleading. You are missing a lot more stuff.
I disagree. Throughout most of history, people lived in extended families, and only recently (starting from 1900s) has it become nuclearized for most of the people.
Mortimer Adler's classic How to Read a Book addresses both the why and how. I'd suggest ... reading it, synoptically, to answer your question.

Simply: reading is communication over time. It enables earlier others to share their thoughts and insights. Often, as suggested in this thread, ideas arising in one domain have relevance in others --- they provide insights, clarity, metaphors, understanding, mechanisms, skills, ...

Exactly, the same happens with the word "technology".

The same climate benefits apply to northern England and Scotland, but Great Britain's grid's capacity has around 10 times the capacity.

(Ireland's grid's peak demand was 6.8GW, Great Britain's 63GW.)

Although the same argument then applies for siting the datacentres in continental Europe, where the grid is around 667GW. Perhaps this is part of Facebook's reasoning for a second datacentre in Denmark.

(Most of Denmark, including Facebook's existing datacentre, is connected to the continental European grid. The eastern islands are part of the Scandinavian grid.)

Though DevOps is haunted by its own monsters in particular that when company starts all of DevOps related things are afterthought and patched by layers of temporary solutions until a person dedicated to handle it is hired and first thing you're meeting with is how to untangle the conceptual spaghetti of technologies.

Seth Godin has a whole schtick on the high value of what he calls “intentional serial incompetence”. Basically, if you’re unwilling to be seen as incompetent, you can’t deal with change. Good summary here - https://www.fastcompany.com/38442/change-agent-issue-31

My own experience has been that if you’re pretty sure you’re one of the smartest people in the room, you have an obligation to ask the “stupid” questions, because the rest of the room will be too afraid to look stupid.

Until Windows 10 IIRC, Windows 8 was also a paid upgrade. Windows 8.1 acted like a service pack so it wasn't until 10 that upgrades became free, in a way. (Unless you're an enterprise customer, in which case 10 wasn't free either)

Some years ago, I learned that I'm better at finding things when high. For context, my GF misplace things a few times a week, and I like finding them before she can. I realized pretty quickly that I did better under the influence, because I didn't rule out places the things might be. When sober, I wouldn't check certain places, because, That'd be a ridiculous place to leave that.

Sounds kinda dumb, but it was an ah-ha realization that extended beyond finding misplaced items.

The output from a markdown to HTML converter is not text content. It's HTML. And it needs to be sanitized before it is added to the DOM.

That's just a quick example. There are plenty of other conversions of user data that can't simply be displayed as plain text and need to be converted to HTML. That conversion doesn't always happen in the browser. Sometimes it's actually just straight HTML that needs to be displayed, but because it came from a user, it needs to be sanitized.

One way to prove that he truly doesn't mind looking stupid would be to list times when he risked looking stupid... and it turns out he actually was.

It's happened to all of us though we dont like to admit it.

I'm sure it's happened to him too and I looked but I didn't see any of those examples listed.

Giving only examples of when people thought he was dumb and it turned out he wasn't... that's kind of just a roundabout way of humblebragging that you're an unrecognized genius.

Sadly I think this undermines the point of the article which otherwise makes a good point.

Just adding another counterpoint to "MacOs is awsome", anecdotal one, because we don't have any other.

My wife (she is not a hacker, just a computer science teacher) hates macos, she preferred Linux.
She used the system I setup for her, and I left it alone. She loved it.

MacOS is created for average Joe that just browses web and has no clue about anything else (like filesystem, directories). Example: Finder, that thingy can't show you full paths. If you try to get to your home directory to get some files you have to jump hoops.

I'm astonished that it is pushed as a developer OS, "because you have 'Linux' there". Sorry, that poor choice of basic utilities (some time ago bash there was ages old), that everyone has to use brew to get anything useful there.

Hardware is nice, but OS, is something that you just overwrite while installing Linux.
If you want to improve, look at an open source project with a lot of momentum, and learn from what people are doing there.

I'm actively involved with Zephyr RTOS, for example, which is backed by the Linux Foundation and has people working on it full time from almost all the major MCU manufacturers. The development tends to correlate closely to Linux kernel as a model, and a lot of the key members were/are Linux kernel contribs, so skills learning with Zephyr can help you move to Linux dev later if you're new to it.

There is a non-trivial learning curve with Zephyr (device tree, KConfig, etc.), but it has more momentum than any RTOS I've seen in my career, and it has a very helpful community, while keeping the technical bar high.

If you prove your worth there, it's also an avenue that can possible even lead to job opportunities, which I've seen and benefited from myself.

That may or may not be of use, but if you want to improve in the embedded space, getting involved with something like Zephyr is some of the best use of limited time in my opinion to learn from some of the better embedded engineers working in the open.
Wow, this describes me to a T. The only difference being, you (Dan Luu) are much smarter than me.

The other day I got confused by a decimal separator on Hacker News and posted a comment saying so. I am pretty sure some people assumed I was stupid. Perhaps they did not want to put in the effort required to understand why some one might get confused in the given situation.

I will admit sometimes I fall into this trap too and assume the other person is stupid. Nobody is perfect.

I have nothing profound to say, just wanted to share this.
Probably about to happen already. Lots of people are depressed and want to act.
Its Wikipedia entry says that it was developed using an (unnamed) toolkit and required A/UX 1.1, so it probably wasn't particularly portable. I'm sure the source code exists somewhere, but the effort involved in resurrecting it would seem to be considerable.

> Is it overt idealogical zealotry to say that the Earth is round and orbits the sun? Is it overt idealogical zealotry to say that time dilates as the speed of light approaches?

no, because these statements do not come with an assertion of imminent, irreparable global disaster prophesized to occur in the nebulously nearish future, unless mankind takes swift action, and we have to act now dammit, because people did the math and this is what we have to do or else! notice that this general framework applies to both topics that you seem to feel very strongly about, and you've lumped your ideological opponents in each of these axes together as one unified "other"! this "othering" of anyone who disagrees with any disparate aspect of your worldview (apparently they're all the same group of undesirables) makes you come across as indistinguishable from a religious zealot. I truly don't mean this as an insult, it's just the most obvious comparison. I know plenty of people who share your general perspective but only a few of them share the zealotry. this specific anthropological phenomenon is very interesting to me, and after thinking about it quite a bit for many years now, it starts to make quite a bit of sense, but further analysis would be unwelcome here.
No, I don't think there is any such implication. Mathematics works by defining some axioms and some rules on those axioms and then people think hard to see what theorems are true in this system. Being able to define something doesn't seem to imply that such a something must exist.
Totally agree - there's a difference between being willing to look stupid and going out of your way to look stupid!
"Looking stupid" is an assessment of what other people think. Eg, asking for the smallest box isn't stupid - Apple expects all the boxes to be good products. Even picking a product randomly isn't stupid and therefore shouldn't look it. The looking stupid part is an assessment of what the store clerk is thinking.

That is a very subtle, fraught and complicated assessment. There is a lot going on to do with the audience, context, risk and the truth. There is a lot going on behind the term "looking stupid" and it undersells the complexity of the social interaction. There are two parties, multiple issues and a lot to think about.

Exactly. E.g. this:
"Although there are some downsides to people thinking that I'm stupid, e.g., failing interviews where the interviewer very clearly thought I was stupid"

This isn't just looking stupid, this is being stupid. Why in Heaven's name wouldn't you at least adjust your behavior when you're in an interview?

Acting stupid can be a convenient way to hold up your belief that you're smarter than the rest. Nobody will ever challenge your belief because hey, if they think you are stupid, it's because you made them believe that, which means that they are actually the stupid ones!
There's some "willingess to look stupid" here, but also some lack of emotional intelligence (which is probably not conscious/willed). There's a humble-brag/arrogance element too (which also marks for some "emotional stupidity").

As in, the reasoning applied to some of those cases is quite Vulcanian-like, maybe a comrade on-the-spectrum?
Android can run on <1GB RAM devices, and I'm willing to bet WSL's port runs a lot less background services. Couple that with Hyper-V VMs being able to release memory back to the host and it probably won't be too bad. (Maybe even lighter than some Electron apps)

Physicist’s nitpick: this is Fourier transform (or its discrete equivalent DFT, not to be confused with density functional theory). FFT (fast Fourier transform) is just an algorithm to calculate DFTs. They are used interchangeably by computer people, but they really are not the same thing.

That aside, yes, it is amazing to play with this sort of things and produce Fourier transforms by shining a light through a physical object.

I remember a lab assignment from undergrad where we de-noised a picture by blocking some parts of its transform before transforming it back. We could remove the noise or the image itself (keeping almost only the noise) by blocking different parts of the beam. It makes the concept of frequency filtering very intuitive.

This is terrible advice, I would call it a lack of willingness to communicate openly. Also even if you are in the highest echelons of intelligence making yourself look stupid will close access to some opportunities that might propel you forward. Also, over time this behaviour might form a habit that will also influence your personal life.
People split classes for visual reasons?

That sounds unwise. I only ever split because the class is getting too large, or because some functionality is better off being moved to its own class. And those other classes also should preferably only have one or two methods exposed to the outside, there's nothing worse than a large surface area unless it's a library class.
