There will be a large market/human-lives-saved benefit from the tech though, even if we never reach 100% self-driving autonomy

E.g. it is pretty standard now that pretty much every car on sale has automatic emergency braking that tries to avoid running over pedestrians even if the driver does not see them, many (but not all I admit) cars have lane-keeping assist that automatically keep the car in the lane, and will automatically adjust the speed to match the car in front and so on (right down to slamming on the brakes to avoid a rear-end shunt if needed). Then there are the self-parking cars, the ones with synthetic overhead 360 degree camera viewpoints, ones that prevent "unintended acceleration" in car parks, ones that read the road signs to let you know the speed limit etc. And these are "normal" cars that a common joe can afford, not high-end six-figure Mercedes/BMW/Lexus/Tesla etc

This sort of tech was science fiction not so long ago, yet now it is literally standard-fit.

There will be a slow but steady "encroachment" of more and more automation into cars as the years go by - you can guarantee that companies like Cruise are churning out the patents at the least for this sort of thing, even if not outright directly licensing technologies. It feels like a land-grab phase right now, even if there is no real intention to reach L5.
I think for as long as I can remember, home goods/furniture has always been on the top floor of most department stores like Macy's.
This article's shadiness aside..

Battery tech just continues to amaze me. Right now the cheapest EVs are in the same price ballpark as mid-range gasoline cars, and range anxiety is fading fast.

I always thought that EVs would get "as good" as gas cars eventually but now I'm realizing that they may surpass them by a long shot. In the not-too-distant future an EV may cost way less, require far less maintenance, be cheaper (and greener!) per mile, be faster and safer, and have a longer usable lifespan, than a gas car. Amazing stuff.
There are ways to get a job without leetcoding still. But they are becoming rarer and rarer.

I think it mainly involves focusing on non-tech companies (who, BTW, are also starting to join the leetcode cargo cult).

I got my current job at a non-tech company (bank) several years ago. I did not get leetcoded back then. The interview was mainly language and framework trivia. Nowadays, we have to subject candidates to leetcode.
Adding and saving annotations/notes/highlights, fast full text search (aggressive preload), double page/single page views, form filling and saving (perhaps not even to the original PDF) are the minimum you really need for "working" with PDF...just "viewing" them is not really enough for serious academic work/research on PDF files. The more well integrated, the better. The functionality should look like in Acrobat, Okular, Mendeley, or similar tools.

If I understand correctly, ~ means raw "invert the bits". Two's complement doesn't enter into the picture - it relates to how the bits are interpreted, which is a layer above what ~ does. One's complement, two's complement, unsigned... we don't care, just invert the bits.

The Canadian govt forms like Visa application forms or Tax forms don't work on any Linux pdf tool that I tested with. The pdf would display empty with a JS error message. This was a few years ago though.

Had to install the linux version of Adobe, which is many years out of date now.
The bit that helps me a lot with Chinese is that once you known the characters, you can deduce the possible meaning of the words, especially in the context of the sentence.

For example, 手機 is "hand", "machine", 飛機 is "fly", "machine" which you can guess means airplane. 鐵路 is "iron/metal", "road" which you can guess could mean railroad. 火車 is "fire", "chariot" which I guess can be a little confusing but it narrows it down to either a car or a train (it's train).
france is such a weird place. In some ways it's a very free society. In other ways it's not free at all. Don't most of the euro countries have weird laws about hate speech like this?
For the Korg NTS-1, I am outputting something other than just note on/off events. The NTS-1 is somewhat unique that its arpeggiator computes arpeggio notes and timing onboard with three parameters: root note (the key you press), the chord pattern (major, minor, dim, sus, aug), and the arp pattern(up, down, up-down, random, etc.) and then generates the arpeggio. The root note is a simple note on, but the chord pattern and arp pattern are controlled through MIDI control change settings.

And the first question - also yes. But for synths other than the NTS-1 you'd have to send each note individually so you will more to do - e.g. keep track of note positions, determine notes in each chord, etc. I might try to do this too. As far as I know, the NTS-1 is the only one that has such a smart arpeggiator (probably because its monophonic and you can't enter chords easily...).
Initial versions of Starlink will not have laser links and will require ground stations to operate.
This is probably one of the first instances that will trigger congress to fix the tax laws for crypto. There will be many more. The current tax code is written for corporate investors and foreign exchange traders, which have little bearing on game tokens, community tokens, and other use cases that will exist. These use cases are not going away and normal people are not going to suddenly file a few hundred pages of transactions on their capital gains forms just because they used some apps.

The US already has that ability to coerce foreign companies. TSMC buys chip making supplies and equipment from US companies, and there's been discussions around requiring foreign companies using US technology to obtain a license to not supply chips to Huawei or risk getting cut off from the US tech network themselves.
Because it is ridiculously easy to overfit your models, and the combined human behaviour producing 'history' is so complex and ever-changing that it cannot be simulated.

The problem is there still are PDF forms many people need Adobe Acrobat Reader for. I use Okular and SumatraPDF to read normal PDFs but there is a form I am required by the state to fill regularly so I had to manually extract Adobe Acrobat Reader from an old Ubuntu repository.

Disclaimer: I work as a dev without a college degree so I'm a biased towards the side of alternative credentials.

I would love to hear other opinions on this subject. Everyone seems to have a different take on adding certificates and online courses to your resume.

Personally, I would see any sort of online course or certification positively as it shows you are learning. Whether or not you can back it up when you get it for an interview is a different matter entirely but having traditional BS/MS doesn't bypass that hurdle either.

The radical (which is usually on the left, or bottom) is sometimes semantically meaningful. In your example, 汁 has the water radical, and it is indeed a liquid. The rest of the character aside from the radical is usually entirely meaningless, aside from possibly providing the pronunciation.

As an example: 果裹猓粿蜾 are all pronounced identically - guǒ - but mean “fruit, package, monkey, rice cake, wasp” respectively. The radicals are more useful: in the last three, you have the “animal” radical (monkey), one of the “food” radicals (rice cake), and the “bug” radical (wasp).

Ask HN: Which maths/physics conferences went online in 2020?
I am studying maths on my personal free time (and also am very interested in theoretical physics), at a graduate level, but I never got to attend to international conferences, as they require to go on-place, sometimes far in the world, and most of the time they span several days.

The pandemics has forced many seminars and conferences to go online (virtually all of those which have not been cancelled), and I strongly suspect that this is the same in maths and physics.

I can browse the web and already discover that many of these conferences are indeed online in 2020, but by asking HN I have these purpose:

1/ discover some interesting now-online conferences that I did not know of (remember, I am studying outside of any academic situation)

2/ ask whether there are good reasons to not keep these conferences (or part of them) online even after the outbreak. I, for one, would love that.

Thanks if you have any suggestions!
An honest question: isn't this what local governments want? I see cities and counties implement two policies: rent control, and blocking development of high-density residential areas. Both measurements will limit supplies (while benefiting incumbents), so naturally people would move away.
I'm working on a garden.

I moved into a house late last fall, so I actually have some space to do so. This scratches multiple itches for me.

Itch the first: I've missed having a vegetable garden since I moved out of my parent's place and into apartment life years ago. While a small garden plot can't wholly replace the need to go to the grocery store for fruits and vegetables due to the inherent seasonality of growing food at small scale, it's damn hard to beat truly fresh fruits and vegetables that were picked not an hour before they landed on your plate. And any surplus left when the growing season is over can be preserved and stored for the winter.

Itch the second: It's _my_ creation, not my father's with which I am merely helping. When living with my parents, my father had his way that he'd like to lay the garden out. Granting that a man who grew up in a rural agricultural community probably knows a thing or about vegetable gardening, watching how he did stuff did always leave me wondering if there wasn't room for improvement. Since this is my garden, I can make my own experiments and decisions on how the garden is to be arranged, and what vegetables I want to grow (e.g dad loves beets; I do not). I've been reading about companion planting, and am eager to try things like growing corn and beans together, or growing chives near my peppers and tomatoes to keep aphids away (seriously, fuck aphids).

Itch the third: It lets me develop useful skills outside of my career in tech. While I have no delusions about quitting being a sys/net admin and going and becoming a farmer, I do think it's important to nurture useful skills outside one's main career.

Itch the fourth: I have something to automate with tech. Gardens do need to be watered. Under-watering will limit your yield, but over-watering is also harmful to both the garden and the wider ecosystem of one's immediate area. There's a goldilocks-zone when it comes to watering, and the just-right amount of water depends on a number of things: what you're growing, your climate, the soil, etc. There is a real danger that before the close of summer, the garden bed will have an automatic, multi-zone drip irrigation system, complete with soil-moisture sensors, controlled by a Raspberry Pi or similar SBC.

During April I built a loft bed frame out of framing lumber. I can post about that too if any of you are interested.
That scoreboard sounds particularly toxic.

Well, yes, people do, and the trick is to love your work and your company. I was definitely doing so when I was doing my own startup.

I've worked before in a place that was mostly people who just show up for a 9 to 5 (or often more like a 10 to 4). It just felt super-depressing to me to look up around at 6pm and the whole floor is completely empty. Didn't last long there, but I guess it was a nice sabbatical.

These days I work closer to 10-12, but if I'm on a good pace in a groove, or someone needs help with an urgent issue, or it's just some self-imposed mental deadline, that can easily stretch the day to past midnight. I would say most of my peers work similarly.
I've decided to learn Python by dabbling in some Django to wite a cms. I'm simply amazed at how quickly you can get something usable with so little experience.

Probably a dime a dozen project compared to most things posted here, but it has an eventual use case for me, and it's fun :)

Thanks for your comment! I have tried the Rad Bikes and I had the exact same feeling like you. No cadence assist for me.

I looked at all the bikes you have suggested, and sadly none fit the bill. I didn't think they would - I have studied the subject extensively.

1. All popular mid-drive motors such as Bosch and Shimano are designed for European market, capped 250 watts, sometimes 350 watts. The max legal in the US is 750 watts, and I really want the max. I might even need the max when bike packing, or simply climbing up the hill where I live (it's pretty bad).

2. All legal powerful motors are rear-hub or front-hub. They can't take advantage of the rear wheel gearing, so they can't climb the hills. Rad Bikes have it written in the instructions that one must not use max assist when climbing uphill.

3. One can find non-street legal motors (how about 3000 watt) and they will climb rather well without gearing, but I want to stay within the law and conserve battery power. They are also heavy, and I might need to carry my bike on stairs.

4. There is a handful of street-legal powerful mid-drive motors, but they are mostly use on custom builds (Bafang, Tonsheng, etc), and even then only some of them seem to support torque sensors.

Then there are other concerns: it's nearly impossible to find full-size folding mountain bike, they are all 20" tire size. The $4k+ tag is about twice as much as I am planning to spend. Most of the bikes have rear shocks (stealing power - see "bike bobbing").
I'm afraid what workers want is not really important. The pandemics became a huge proof-of-concept for many C-levels execs. The vast majority of them were absolutely sure that if the employees start working from home their companies would fall apart immediately. To their big surprise, that actually didn't happen when quarantine and WFH was enforced by governments. Now they can't stop thinking of WFH as of a huge cost-cutting opportunity.

Nobody asked employees if they wanted open offices or not, it was simply enforced on them. The same will happen with WFH - it will be simply enforced, sometimes with a plausible, good-sounding justification.
I think both ideas are good, and I don’t find your dismissive objection persuasive. The point of hiding all but top-level posts wasn’t about making comments.

It was about reading them. Specifically that with fully expanded comments, users have to scroll past even downvoted, flagged responses to the top comment before seeing the second-highest voted top-level response.
So the person with all the power, the one who speaks in plural about what he allows is suddenly some how the victim?

Please just delete all my comments. Including this one.

It was a big part of my degree but I never worked in finance professionally.

Backtesting is great for validating ideas initially. Especially, to see if it holds up through abnormal markets like '08, or the volpocalypse, or the recent crash. Watch out for curve fitting, though.
First thing I tell anyone when they say "this code is slow because of X" is to profile it. Profile, profile, profile! More often than not your assumptions are wrong.

There's a myriad of tools out there for profiling, some language specific, some not. Learn at least one of them well, how to read flamegraphs and how to benchmark properly (warmup code, synthetic vs real traffic, etc). There's definitely a jump between making guesses and hoping you improve performance vs truly understanding what your code is doing.
But if a human is piloting a helipcopter with a "gorgon stare"-esque technology attached, seems pretty much the same.

I guess I'm unsure what about the autonomous flying is what draws people ire, rather than just overhead surveillance as a concept.
Why is self-updating software still a think? It has been known to be a potential high security risk since years.

I mean there are some special software where it still makes sense, but Adobe software clearly doesn't belong into this category.
Obviously transistors have gotten way smaller, but it's not entirely fair to compare transistors in a sound chip to something in a microprocessor.

Anything that's driving a speaker is going to have pretty large transistors. Additionally the power stage of chips generally takes up some room. It'd be a lot more comparable to compare similar basic sound output chips... I bet they don't have more than a few thousand transistors even today.
This is why cycle time is a much more useful metric. The book "Accelerate" shows what a mature conversation around software metrics should look like.

EDIT: To be fair, my point may not directly address yours. "Value" is still a tough thing to determine.
When my small SaaS customer calls and asks for an extra extension at current hard times, then all I need is to open up Rails production console (pry) and live type in an ad-hoc code with auto-completion aid:

It is done now! Good luck! Bye! - end of call.

Which is perfectly reasonable. They're looking for an email address that they can reasonably expect to deliver mail to, not just an address that is technically valid.
