I have a hand cart / furniture dolly that's almost entirely plastic. The only metal bits on it are the axle and the handle. It's perfectly durable and I've used it to cart around items that weigh 600 lbs. (300kg).

It's also a good little example of where plastic is good and where it's not. The axle and the handle get the largest amount of stress, so they remain steel, while the body of the cart can be a trussed plastic mold to achieve the strength needed.

Portable gas cans are another area where plastic wins in my book. It's lighter, more impact resistant, and cheaper to mass produce. And it don't rust! Sure, there are probably niche cases where you want a metal jerry can, but for most applications a blow-molded plastic container is better even if it wasn't also cheaper.

But I still think a cheap, strong, and corrosion-resistant (or -proof!) metal would be revolutionary. For all the structural uses where plastic won't do. Vehicle frames, airframes, bridges, tooling, etc. My holy grail here is something that's basically aluminum, but without the fatigue issues. Oh, and closer to steel in cost.
To be honest, that part of how the internet and browsers work is beyond my knowledge. I just know how to create HLS packages, and then see how the browser makes the multiple requests in the network tab. If browsers are smart and keep connections like that open vs renegotiating per request then it makes sense to me. Maybe this will be my today's TIL for me.
ah yes you're right. perhaps one front wheel is powered somehow? is that mechanically feasible with the technology of the day?
You'll be able to tell when it really clicks for them when they end up removing xmonad from their machines replacing it with i3.
I think it’s rubbish. I smoke weed every day and it is not addictive.

I’m simply adjusting my body to weed frequency. I need a higher concentration THC over time because my body raises in frequency.

But I live a clean life. Many mix weed and cigarettes.

To me, cigarette smokers are dead. I don’t care what they think, I don’t associate with them, I don’t go where they go.

Clean and healthy weed smokers know this.

UK is in dark ages in terms of weed culture. None of them knows what they’re talking about.

They don’t smoke weed. They look and numbers, think things, and write nonsensical documents.

That’s not research.

I smoke weed and study neuroscience every single day.
I've heard a number of people assert that sweet potatoes are more energy dense per acre, but it looks like that may only be true if you consider complex carbs, and even then there are contenders. They may also be talking about one particular strain whereas calorie per acre lists like to say "sweet potato".

Sugar beets appear to be higher than sugarcane, but they're under substantial threat and they don't like the tropics. Then there's palm oil, which is such an environmental disaster that it practically ranks as a humanitarian disaster. Then something called chufa (a nutsedge), something called sacha inchi (Inca nut, a kind of spurge), and cassava/manioch bringing up the rear barely ahead of corn.

But some of these have a lot of calories in the form of oil, which means two paths are required to convert it to fuel. From a health standpoint, flooding the market with a cheap 'waste' product from a particular food process has kind of been our downfall.
Yes I did read it. Why do you suspect I had not?

To be more explicit, I wouldn't agree it's most often the government making monopolies. There are plenty of cases where government regulators are captured by 'natural' monopolists (or otherwise large players) who then entrench themselves with regulatory moats, serving only their interests.

And even government made monopolies aren't _well_ regulated IMO, for example telcos. A freer market would need controls to prevent consolidation from locking in customers by simply buying up all the spectrum and lobbyists.
Are you referring to the "first-class" cabin on the vast majority of domestic flights? OK, maybe.

Bin space used to be plentiful in the back, so I'll give you that. And maybe you're checking bags. But here are some things you're missing out on in coach in 1980 that you get up front today:

- You're first-on.

- Drinks before takeoff (it doesn't have to be the champagne that comes by on the tray, you can ask for anything).

- Followed by a real service: drinks, appetizers, entree, dessert.

- Pillows and blankets that are actually comfortable. More than you'll know what to do with.

- Amenity kit, robe, slippers.

- A smoke-free environment.

- The brass ring, a 100% lie-flat bed surrounded by a privacy partition.

- You're first-off.
Right/control click does not work on a Mac. On Safari and Firefox, they both bring up the contextual menu; on Chrome it just highlights the hex.
Can anyone find a version of A86 that actually encodes some information in its output, or is this just a legend? It produces different opcodes for some instructions than MASM, but so do DEBUG and various other assemblers. And the same instruction repeated multiple times always assembles to the same opcode as far as I have seen.

To prove some program was made with A86, there would have to be a more specific signature that wouldn't match any other assembler, like a copyright message encoded bit-by-bit in the opcode choice.
You have to enable "emoji stickers". Then you type two emojis and you'll see a sticker suggestion pop up on the top of the GBoard if it exists.
This is patronizing to say a programmer could write algorithms that are complex enough there is a major dedicated to it at most universities. You have to realize that you're probably thinking of using a naive solution that produces an extra another order of runtime complexity for datasets that reach 100GB easily.
Hit the nail on the head. Promoting housing as a vehicle for wealth accumulation will be viewed as one of the greatest failures in modern economic policy in the West.

It's easy to blame Wall Street, corporations, immigrants, but the reality is much simpler: these policies are wildly popular with the first few generations of voters who saw their property prices go up, so governments are deathly afraid to touch them.

The next generations are the ones who suffer, but they don't vote (yet). Politically safer to kick the can down the road and make it someone else's problem in 10 to 20 years' time.
Nice I was addicted to this exact game on a mobile app many years ago. Thanks so much for making the source code available! Gonna be fun to dig into it

Edit: found the app, https://apps.apple.com/us/app/noodles/id967624193

Looks like they have a sequal to it and it includes a triangle grid!
why would you stop using cat or dd? I use cat everyday, what am I supposed to replace it with?

what replaces dd?
and roast it

hopefully not although Slor HN could be a variant of Show HN but for roasting.
I've seen every Ghibli film except the Earthsea film, and I'd say the best are Spirited Away, Princess Mononoke, Princess Kaguya, and Totoro.

That said, I've liked pretty much every film they've made except Kiki's Delivery Service (I found it a bit dull) and Howl's Moving Castle (it just didn't work for me). They're pretty much all worth watching at least once.
FUD.

The only radioactive thing in that water will be Tritium. Tritium is not dangerous to humans.

Here's a quote from the EPA [1]

Tritium emits a very weak beta particle. People are exposed to small amounts of tritium every day, since it is widely dispersed in the environment and in the food chain. Tritium primarily enters the body when people swallow tritiated water, inhale tritium as a gas in the air, or absorb it through their skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Since tritium is almost always found as water, it goes directly into soft tissues and organs. Tritium is excreted through the urine within a month or so after ingestion. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.

Removing yourself from the equation makes it easier to see: imagine a ball on a string in a car. Something happens and the ball moves forward relative to you. It’s not hard to see how you might assume a force pushed the ball forward.
For some of the topics I really cared about, I wrote notes on my website. See the "Notes" section at the front page of https://www.jviotti.com.

For example, here are some notes on Automata Theory: https://www.jviotti.com/notes/automata-theory and CSP: https://www.jviotti.com/notes/csp.

I don't expect anybody to look at them though. The process of creating them gave me all the reward I was looking for at that point.
Given that the 8086 has SI and DI with a +imm8 mode, like the (IX+imm8) and (IY+imm8) instructions on the Z80. I do wonder if Z80 CP/M machines were the real target rather than the 8080.

I did write an 8086 assembly based Z80 emulator (in the late 80's) that was surprisingly compact and had acceptable Z80 performance on a 12MhZ AMD 80286. It passed CP/M system calls to Concurrent DOS.

I should see if I still have the code and run an emulator torture test to see how bad it was.
well before this announcement it was 0. So I think it's pretty great.
Based on some testing just now, it looks like for synchronous mode single-page PDF is supported, but if you try to OCR a multi-page document, it throws:

An error occurred (UnsupportedDocumentException) when calling the DetectDocumentText operation: Request has unsupported document format

Normally, I just use pdfsandwich [0] for PDFs, which has been good enough generally, but I'm tempted to switch to using textract, because it's been much better at rough scans for my tests.

> what if it doesn't affect me the way it does everyone else? Would that mean there's something wrong with me?

If there was, wouldn't you want to know?
Just turn the resolution down, don't render anything smaller than the Planck length.
No, the absolute worst possible choice is geoengineering -- literally moving mountains to correct the effective radius of the earth.
I think we're both seeing a generational difference here. Those of us who remember those times know in our bones how much better things are...even if you don't want to look that hard. That was 15+ years ago. A lot of HN probably wasn't around to remember.

I don't want this to be a "kids today don't know how good they have it" post, but that's playing a role. However, that attitude is probably what's going to keep driving things to get even better.
I have the reverse situation. I have had a Zipcar account for ~5 years, and despite the website being pretty clear that I'm on a paid monthly plan, I haven't been charged for a single month ever.

I'm still charged for the actual hires I make though.
Depends on the size of the city, I suppose. A 15 minute car city like New York or London is almost certainly impossible.

In a comparatively-suburban "city", it's absolutely possible and probably fairly common. Of course, you'll likely have to leave the city far more frequently, and those trips may take longer than 15 minutes. By contrast, you could easily spend your entire life in New York without ever leaving city limits.
what are the implications of this for users? are there ubiquitous QOL mods that a lot of people run on VR chat?
Not really.. most of what states like California grow is exported far and wide.
what do you actually want to do? I have https://github.com/coder/code-server and https://jupyter.org/hub running on a PI, along with tailscale on the ipad and pi. This allows the IPAD to have a full editor, and a shell onto the pi.
Then give them what you've got!

I've put my own project out there (https://github.com/hofstadter-io/hof) and got feedback that I would never have, had I not. I now use the feature more than the user does :] What's even more motivating than having them tell you they want it, is hearing about how they are using it, and then learning what household name companies they work at!

They also found bugs that I would not have, just by using the tool differently than I had. Your early users will be tolerant if bugs are what keeps you from releasing the first version. No software is bug free, no product survives first contact.
I agree with most of the article's points, but not with the second one of these two in particular (pasting the first one just to keep the context, I don't disagree with that one):

"Facebook's friend counts and "like" buttons turned human relations into a depersonalized metrics competition.

Keeping up with the volume of posts became a chore, which was why from 2009 on Facebook's news feed defaulted to an algorithmic, rather than chronological, sort."

I did not find it very difficult or a "chore" to casually keep up with the posts from my friends, and I doubt many others did (or that users even felt they needed to catch up with every update). But just keeping up with my friends likely did not have enough monetary value for Facebook, and that is in almost all certainty the actual reason why Facebook switched to an algorithmic "sort". Which by the way is also a giant misnomer, since it is entirely different content, not just "sorted" differently.
If the chemical fuel can work in a fuel cell, then where it's relevant (high latitudes in winter), you can get 100% efficiency in the chemical->used energy step by using the fuel cell for heating.

The electricity->fuel step struggles to heat 50%, which is not a deal breaker compared to other sources.

The hard bit is storing hydrogen.
The sad parts involve kids. If that doesn't phase you the CIA has some wonderful career opportunities they'd love to talk to you about.
Yeah but that’s illegal
One of their claims is that you can travel end-to-end in 20 minutes. If that actually worked and was easy to use I think most of your advantages would not be super relevant.
Modern antivirus software is arguably a scam. To avoid having to determine if a program is actually malicious (which to do definitively would require solving the halting problem), they simply mark anything they haven't seen as suspicious. Granted, malware developers did use obtuse binary formats, packers, and strangely tweaked executable headers for years.
I’ve grown a handful of things indoors using the Kratky method and some grow lights. My apartment gets very little natural light, but otherwise the grow lights are not necessary. I found it to be economical, and really fun to grow. Cilantro and basil in particular can be very expensive at the store, but I can grow loads under a single LED light for very little $$ per month.

I also grew mint in a big 5 gal bucket, and it grew like a weed. I made mint iced tea that tasted delicious. Really easy maintenance too. I would just fill the water occasionally and add basic nutrients. The mint lasted 1 year in the same bucket and the roots were nice and white/healthy.

The only real things you need to do is have correct nutrients and a black container that stops light from being let into the reservoir and algae growing. Otherwise super easy! Much easier than even houseplants that you have to remember to water! My system was basically automatic and I’d check it once a week. The lights were on a basic timer and ran for ~16hrs a day.
yes, spirited away is hands down the best ghibli film, for that ability to grab your spirit and transform it alongside chihiro's (the young protagonist). it's probably one of my top 5 or top 10 films of all time.

i liked mononoke, but it felt heavy-handed in comparison, so it doesn't rate as highly in my book. it would have rated way worse had disney gotten its way with it.

edit: totoro would be #2, kaguya and grave of the fireflies would be tied for #3/4, then howl's moving castle at #5, then ponyo, mononoke, and kiki's delivery service would be among the remaining top 10 spots for me.
So an earth-based version of a Topopolis[1]. Cool!

You sum up exactly the problem: the WSG technique does not give the whole global sequence of bases, from telomere to telomere through all of the centromere and for each chromosome branch.

This is what I would like to see as an affordable product: get the whole sequence, so that ultimately one could theoretically re-synthesize their own chromosomes in the future. And get it now that we are still young and there is not too much damage in the DNA, information to be stored for later.

One point in what you wrote: the blank pages (introns) can be really important (like for gene expression regulation, through chromatine folding, or promoters of transcription), we just can't be sure, and that's why it is paramount (when thinking of chromosomes synthesis applications) to have it all.

About the specifics of our discussion: Again, ambiguity! Because we're saying the same thing.

When I say it does not give the sequence, I mean the whole sequence (not only local subsequences), which means including the context.

(Although the notion of context is actually meaningful only if we are talking about local subsequences, as the global sequence is the context (or includes the context, if we reduce "context" to mean the reference global sequence against which the subseqs are aligned)).

Of course with your meaning you are right.
I’ll also add that getting started is easy and cheap. Forget all the complex solutions, and start with a $10 plastic container or 5 gallon bucket. All the pre-made stuff is a waste of money IMO
I'm not sure this will help you hire people who don't do self-contained projects of a certain size (1-20k LOC) and who are scrupulous about maintaining confidentiality.

Personally, I would have plenty of code to share, but not code that has the cohesive story that the interviewer probably wants. Most of my personal projects are small libraries, huge projects, or tiny experiments.

I would never share code written for an employer or a client, also. That is their code, not mine, and I would hesitate to work for any company that tried to ask me to share it.
You appear to be under the absolutely ridiculous illusion that "academia" as a space for discussion is a self-evident isolated bubble of safety. I wish it were that, and I literally work most days to try to make it that way, but it ain't that way.
My word of warning though - unless you are well connected, you cannot jumpstart a company by word of mouth alone. Too many great ideas have sputtered out because the founder was too proud to look for customers.

If you are bootstrapping, you need a plan from Day 1 on how to get your idea in front of new people. A Show HN post ain't going to cut it.
I used to play this exact game on a mobile app. One great feature was the ability to click and hold to "lock" certain pieces into place. Like you pointed out, there's certain pieces (on the edges) that only have one possible configuration

My 5x5 is record is 28s on my 5th game. The strategy is actually really simple once you get going: run through and identify all the "lockable" (only one possible configuration) tiles and then run through the consequences of those configuration and keep repeating
Decent deal. Probably <4k if purchased and assembled within China. Cheaper than most electric mountain bikes.

Looks like electric ATVs/UTVs are around 15k, which would be a rough comp.

Electric bikes / scooters / etc will hopefully become much more commonplace. Way cheaper than cars, and potentially more exercise. Hopefully more special purpose trails for bikes / pedestrians are created to accommodate demand. Certain places like the Netherlands do a great job at accommodating non-vehicle commuting.
Since VRChat isn’t open-source and runs the servers they can do whatever they want. They could add in required ads and telemetry. They could integrate blockchain. And they can do this five years from now when they are much more popular and much larger communities are tied to them.

If you’re upset that they’re banning modding and adding an invasive anti-cheat, it’s a good time to look for alternative VR platforms or start creating your own. This is one of those cases where "open-source" means something. And while the meta verse isn’t small or new anymore, it’s still experimental buggy stuff, so a small team working on their free time may actually have the potential to compete.
"Cheating", IE sideloading anything useful or improving beyond the base app? Sounds like they want to compete with Second Life for imaginary scarcity.
Lol I grew up in the suburbs of Calgary, itself a midsized and quite affluent city, and there's violence basically anywhere there's public transportation. There were murders in the suburbs. Drug use everywhere.

Look at what's happening this year, basically every city is experiencing a major wave of gang shootings, drug activity, etc...

Europe is much, much safer. Never seen drug addicts shooting up and harassing people on the Paris Metro, it's an everyday occurrence in any major (and some not so major) Canadian city though.

Also it seems to be a concern to OP based on comments.
Once solar/fission/fusion power has become abundant enough, we can start to engineer the atmosphere to a desired composition of gases, storing any hydrocarbon byproducts in massive natural underground wells, in case we need them again some day.
This phrase implies that there are some "true colors", but are they? People see colors in weird ways, and it is a bold move to declare them to be the true ways.

i don't get why so many software companies want to prevent modified clients. The fact that they can detect the client is modified (and kick them out) means they could've gone a different route - allow the instance host to choose whether to allow it or not.

For some instances that are public, and needs rules and clients to obey those rules, it would make sense to ban modded clients. But for some private instances, it doesn't make sense to ban anyone, as it's private and presumably accessible to only trusted parties. The instance creator ought to be allowed control.

In a similar vein, the new minecraft reporting features (https://www.minecraft.net/en-us/article/addressing-player-ch.... ) affects private servers as well, and it's not an opt-in by the server admin.
Very fun, although I don't really feel like it takes much skill. Seems to be a chill puzzle experience and doesn't scratch the same brain itch as something like a Rubik's cube or Loopover (https://loopover.xyz/).

I did the 20x20 in 32:31.596 and now feel like I can close this tab :P
