Linked lists require you to be on the node in order to do an insertion so it’s generally not O(1) it’s O(n) with sky high constants. Thus for random inserts arrays are actually faster.

If you have a degenerate case and are never traversing nodes, you’re still likely better of with a rung buffer, array list, 2 different stacks, or various other options. And frankly you’re never going to endlessly just insert data without reading it.

Red Faction, which was mostly taking place in underground mines, had generic deformable/destructible terrain reminiscent of Lemmings terrain, but 3D. It was artificially limited in some ways, otherwise you'd just drill your way straight to the level end (similarly to some Lemmings levels with unpiercable material).

Drilling through was not just a gimmick but actually part of the game, e.g instead of finding a key à la Doom/Descent, you'd have to detonate a rocket, a mine, or a grenade at walls near locked doors to create holes big enough to go around them (took me a surprisingly long time the first time to figure I was supposed to do that, especially as the level is intentionally deceptive as you have door with buttons/keys before).

There were also actual boring machines to help you drill through big time. You could make bridges fall into a chasm by blasting both ends. In enemy-crowded open areas you'd have to create your own cover by carving holes in walls or in the ground.

Trivia: Red Faction was initially due to be Descent 4 (as a prequel to Descent), but turned into a on-foot FPS in a different universe.

It is a good idea, however it is too late to execute it well at this moment. As a society we should put incentives differently, so that things like adtech and cheap imports from China get less incentives, but health and solving social problems get more than today and can attract and retain more talent.

I can relate. I had a pretty significant stutter growing up. Nothing, and I mean nothing, I hated more than having to pick up the phone. I always made it a point to be as far away from the dreaded phone as I possibly could (just so that I wouldn't be expected to pick it up when I was nearer to it than everyone else) when inside the house. Once my little sister figured out that I had this weird speech impediment, she would run up to the phone every time she heard it ring. My parents wanted me to face my fears - they meant well - but man, what a horrifying experience that would be ! The ceremony I had to put on just to utter the word 'hello' still gives me nightmares. I've long since grown out of my stutter but talking over the phone still isn't something I look forward to.
Linked lists are O(N) random insertion as you need to traverse the tree to locate the correct node. The only way that they are always O(1) are a degenerate case better suited for another data structure. Aka if you want a queue then use a ring buffer not a linked list.
It'd be interesting to see what happened if they encoded an additional time parameter on each 'view' (input image pixel). Surely someone is already trying to extend this technique that way.
Vocabulary as a Meta Mental Model
Is your starter four days old from dry/dormant? Or did you liven up a wet one? The reason I ask is my starter was purchased online and arrived as a sachet of powder. And it took at least a week if not more for it to be ready. While the thing was just beginning to activate it smelled like old socks and bad cheese with a whiff of cabbage to make things really revolting. Then one day...it smelled of bread. Even a bit buttery. And for the past six years it’s been going strong with the same mild breadth yeasty buttery smell.

Anyhow what I’m saying is that 4 days seems too soon to start using in my limited experience.

Apparently in the first days there are many bacteria fighting for territory and until the right ones win it’s gonna smell like death!

> if you're reducing the list to a scalar, you lose all the benefits this article wants to claim.

Not quite - for example, these both benefit from foldr, despite each producing a scalar:

and, or :: [Bool] -> Bool
and = foldr (&&) True
or = foldr (||) False

... as they can both "bail out early" without evaluating the entire list (if they find a False or a True, respectively).

The distinction lies not so much in "are you reducing to a scalar?" as "can your binary operation be productive without evaluating its second parameter?" - or, if you prefer, "is it ever lazy in its second parameter?". If so, then foldr may be appropriate.
Ask HN: Recommendations for online games for grandparents and grandkids?
My parents are over 70 so they're basically required to stay at home now due to COVID-19. We usually see them a lot, and our 6-year-old daughter will really miss them since according to the models we might not be able to see them for anywhere up to 12-24 months. She hates talking on Skype but one thing we thought of was playing some sort of game online which would keep her interested for longer periods. Does anyone have any recommendations for a game that would be appealing to grandparents and grandkids that could be played online? We play some simple card games with her (Uno, Rat-a-tat-cat etc) and she likes playing some board games too. I guess there a plenty of places to play things like classic board games online, but surely there are more interesting games too these days? I'm totally out of touch.

We're pretty much a Mac-only house and also have an Apple TV, they have a recent-ish iPad but their computer is a PC. Does Apple Arcade have anything like this? Ideally it would be something with a simultaneous video chat, although we could also do that separately of course.
The comments bridge these gaps. Production of lactic acid allows for the production of ATP in the absence of oxygen. It’s like a buffer for peak loads. The heart’s load is heavy, but relatively steady. It doesn’t have the ability to have peaks in output. It also can’t afford to not be supplied with a constant supply of lot of oxygen to feed the mitochondria.

As a bit of a side rant: biology is complicated, that doesn’t mean good work hasn’t been done. I notice many people discredit the field of biology, but eventually make fools of themselves when talking about it.

The thin layer on TCP leaves a lot of things to be desired. Such as knowing if the other end has disappeared and won't ever come back.

Last time I used ZeroMQ was ~7 months ago at my previous job, so maybe things have changed since then, but having to write hacks to see if the other side is still there or not is absolutely terrible.

Also, the Python bindings did not like fork() without exec, which yes is bad and all, but is still something that is done every so often in real world large programs.
Indeed! There is a certain thoughtfulness in a code/build/flash/test cycle in the embedded world, which Pigweed seems to see as a problem and tries to fix. I can (and often do) write code for many hours (sometimes days) without a flash/test cycle. I follow a very different process when I do a React based frontend and I don't think it is anywhere close to being suitable for embedded systems.

The data does not support the common opinion that airplanes are terrible for the environment. Their total contribution to for example CO2 is tiny compared to industry and electricity generation.

Somehow the climate activists have decided to make a lot of noise about flying but it's mostly unfounded. They go as far as using very old models of planes in their calculations (e.g. a 737-400 model) and claiming that's the amount of CO2 per passenger of all air travel. While that model is out of use by the airline for at least 15 years already. It was designed in 1985.

So beware of the data and tricks like this when you're told flying is so bad for the environment.

I wonder if the strict lockdown measures that are needed to try to contain the covid-19 virus perhaps will not be enough to contain the covid-19 virus, but as a side effect will extinguish all other virures with lower Rs transmitted among humans, such as the flu, etc.

That is, that after 3 months of strict lockdown and 9 months of pervasive social distancing, the only virus you will be able to catch is the covid-19 virus, until new viruses coming from animals appear.

That’s entirely the point of hydrogen fuel. The process of producing or using hydrogen does not pollute. You have decoupled pollution from energy storage.

Hydrocarbons pollute by their very nature. In order to have a carbon neutral hydrocarbon cycle you need an impractical number of CO2 capture facilities.

I generally agree. That said, we tried the personal responsibility route, and then the bars packed up for St. Patrick's day and the airports ended up becoming giant petri dishes - literally overnight. And then many, many, many people decided that "don't panic" meant somewhere between clear all the shelves at every store and ignore the problem until it goes away.

I don't envy the local governments trying to contain this with almost no data and no help or direction from the federal government.
Another Soviet technology in software development, sounds very interesting but hard to find information about it: It is named R-Technology a visual programming system said to be still used for critical software in the Russian Space Program:

"The essence of R-technology is the use of weighted, oriented graphs to express control logic and to enforce good programming style. Unlike other developments in visual programming, R-technology can accommodate many programming languages and has been used for numerous development projects. Despite the fact that it has been extensively documented in the Soviet literature, it is practically unknown in the United States."

The credit card is always the same germs while the notes are new germs every time they change hand and can spread nasty stuff much more easily.

This is sadly a very realistic comment.

I do not have any stakes in that conflict (live in France and loosely know a few people with Jewish and Palestinian origins) and this is how I see that conflict with my untrained eye. People fighting for something hardly shareable (land) with hartred on both sides.

One case of such a situation which tuurned fine and that I am incredibly proud of is the relationship between France and Germany. 1914-18, 1939-45 and now school exchanges where children meet other children (and to my dismay - communicate in English...). Not French meeting Germans, just kids meeting kids.

I already mentioned that earlier but one of the greatest moments during such an exchange was a football match where they had spontaneously mixed teams, not Germany vs France.
I don't think it does. 'Strict' doesn't add an implicit ! to nested patterns (so (s,l) becomes !(s,l), not (!s,!l)), and 'StrictData' doesn't change anything about the tuple, which comes from a different module.

You can easily find the person who is holding rather than distributing the money. In fact, you looked at them in the mirror this morning.

I am voluntarily (10% family-preservation, 90% community service) staying in my house. I’m now “hoarding” (to use your hyperbolic term) all the money that would normally go to fuel, eating out, and entertainment.

The restaurant, movie theater, and gas station owner would, circumstances permitting, surely prefer to be able to serve me and I likewise.

Why don’t I just mail checks to people that I’d normally buy from? Because I don’t know what my own economic future looks like. Will I have a job in 6 months? What will my retirement savings look like then? Plus, I can’t just send the money where it would have gone and also send it to the people who are now selling me more at-home food or new goods/services that I need to be productive at home.

I’m fortunate to work as a W-2 office worker/spreadsheet miner, at least for now. If I were a bar, movie theater, or auto repair shop owner or worker, I’d be in a lot worse shape.

This is not a Bezos, Gates, Musk driven problem. This is driven by the inability of the consumer to consume normally.

Well in my country (Poland) with all the noise and confusion some rational procedures get implemented. Supermarkets limit strictly the number of customers inside. Cashiers get physical protection from customers. Contactless payment limits have been doubled. Etc.

So we are getting time for implementing changes and the life can start returning to 'new normal'.
I think that household grocery demand will be permanently up - the switch to working from home, and having kids be home instead of school means that suddenly we're home much, much more than before and eating much more meals at home.

So lots of food supply that used to go to restaurants will now be going directly to homes - it does not affect producers much, but it's a very different distribution chain than what the restaurant purchasing uses/used.

The article implies that rockets burn 100% of their fuel, which is an oversimplification for most thrusters. There's also a fair amount of residual fuel and oxidizer in the piping, at least part of which is dumped into the environment.

4 days from the start. Just flour and water. I didn't buy anything but the flour. I mixed them up, brought it outside for a bit to catch some wild bacteria and yeasts, and I've been stirring it periodically. I put it in the oven with the light on a few times to speed things up. Every day I add a bit more flour and water. It currently smells like yogurt and is full of small bubbles. I think it should be ready to use in another 2-3 days.

OP hypothesis seems to be correct.
O(N) random reads and O(N) random inserts can quickly turn a wide rage of things to be compute bound. Creating a linked list from scratch via random insertions for example is an N^2 operation with surprisingly large constants.

Now sure, if it’s small and you’re only creating then reading it once then that’s fine. But, you’re assumptions need to be accurate or you just created a problem.
