"If we don't know whether a closed form solution exists then how can we even know if it's deterministic.

You can prove determinism by finding me a solution that's closed and deterministic."

Why would it be necessary to have a closed form solution to know that the solution is deterministic? By the first reference in my previous comment, two identical initial conditions lead to identical time evolutions. That is literally the definition of determinism.
True, but I always found that those with higher reputations were given preferential treatment or seen as “superstars” of the forum. Similar to how people with large followers are considered the same these days.
This is the kind of good, simple advice I always love to see. Keep things simple, have each part of your code do as little as possible, make sure everything is as easy to informally reason about as possible.

I also like the part about setting reasonable limits on records returned early on. That’s the kind of simple early optimization that makes sense. You can always increase limits later but it can be harder to reduce them, especially if customers have started building with your product.
Sure. In the Rust ecosystem, if you submit a pull request to a library it is very common for the maintainer to release a new version soon after. Even patches to the Rust compiler repository are released to stable in a matter of a few months (and the very next day for the nightly channel that many people use)

There's always workarounds and so forth, but it is really empowering to be able to have an impact over such a short timespan
Running these lockers in the style of a food truck (or ala Amazon's own Treasure Trucks) seems like a good win win, avoid the permanent eyesore, upsell or cross promote things, bring a few jobs to the city ...
I'd say the analogy is closer to, they'll x-ray your package to make sure there aren't any prohibited/dangerous items.
I wish subjects enumerated the tools up front so it is easier to fill in the gaps and make connections.

Tell folks they'll be using input and output from various places, numbers, strings of letters and bytes (images, video, crazy stuff), conditional logic to make decisions, a couple of key "data structures" to group data (lists, dictionaries), and organize code (functions). You could cover all of these in an hour lecture, then dive into them on subsequent lectures.

They'll absorb everything as they proceed, but a high level helps immensely to help organize concepts.

I wish other subjects did this too.

I also like that my chemistry teacher admitted to us that we were learning lies in General Chemistry. And then again in Organic and Physical Chemistry. We were being taught models that would be continually refined with new information.
I don’t know that I would consider not having a plastic bag a “grave” inconvenience.
Why consuming water from caffeine-containing drinks is different from consuming pure water? I've heard many times that drinking tea doesn't count into these daily water-consumption goals, but no one mentions why.

I took my pixel 2 to a repair store and they just told me right away “there is a 30% chance that the screen will smash if we replace the battery”

Pixels have become so much worse than the iPhone ever was.
Shit country army hydration "pack": half a teaspoon of sugar, half a teaspoon of salt to ~1L of water.

Tastes like shit, but damn it cures hangovers. Also, probably hydrates.
This user says they have IPV6 with FiOS: https://news.ycombinator.com/item?id=27985103

I had read somewhere that a lot of waste(supposedly recyclable) from the US ends up in these poorer asian countries. These countries that actually don't have a lot invested in high efficient recycling systems.

But this article just shows the data where the water gets polluted from mismanaged waste. But not where this plastic comes from? I suppose it's not the full story then?
I read somewhere about surviving being stranded at sea, that losing salt is not really an issue. The body doesn't care about how much salt it has, only what the concentration of salt is in the blood. As you lose water due to sweating, even through sweat does have some salt, overall the body is losing more water than salt, and therefore blood salt concentration increases. Of course over long periods you will deplete your salt reserves, but this will take a while.
So drink more water than V8 or gatorade to keep you balanced.

Setlor app to help students find roommates and housing
Relocating to the US at 24 years of age was not only exhausting but also chaotic. It included weeks and weeks searching for accommodations before the move, followed by the culture shock of being in a totally new place.

Does every student experience the same with relocation? The more people I spoke to, the more my suspicions were confirmed.

A lot of great ideas start from a place of empathy, and that is exactly how Setlor began. It started as 4 years ago brainstorming in a dorm room on a piece of paper to using Figma to designing #UI/UX, using emails to communicate to shifting communications on Slack, using Google sheets to address bugs to manage the entire project on ClickUp. Knowing nothing about the software development to finally evolving into what we’ve wanted it to be.

setlor is what I’d like to call the guardian I wished I had when I first moved here. The app is solely dedicated to finding your preferred accommodation and roommate so you can ease into the process of relocating. Setlor narrows down your available housing options according to the universities you choose and connects you to people looking for the same. Setlor currently has 10 universities listed on the app. You can comment below if you’d like to add your university to the list. Help us help you relocate with ease.

North America here refers to the whole N. American continent including the isthmus of Central America and the archipelagos of the Caribbean Seas.

The US is responsible for one half of one percent which is pretty good.
Gravely inconveniencing, really? Adding 40 cents to your bill if you forgot your shopping bag is a grave inconvenience?
Interesting that they did not mention beer.

Yeah, let's just all sit back and carry on business as usual while pointing fingers at whoever is the worst offender at the moment. That sounds like a good idea.
Buses and bicycles do not have tires?
I'm familiar with that, why I mentioned "patched" in my above comment. It's still a tenuous position to be in, unless you enjoy diagnosing errors rather than working.
Sure, that’s all true. My concerns are somewhat unrelated to celebrating our success, though. I don’t believe Americans would have the experience, social customs, physical stamina, emotional fortitude or knowledge to survive reasonably well if conditions took a serious turn for the worse.
> the difference between "IDE" and "enhanced text editor" would to me be the intrusiveness.

I feel exactly the same. I hate it when IDEs pop up some autocompletion suggestions that cover up exactly the part of the screen I was reading. Or reformat the code while I'm still typing, making the cursor jump around like crazy.

Automating such features means they're counterproductive in at least 5-10% of cases. I prefer having nothing automated but everything accessible in an efficient way. And that's why I don't care when people say their favorite IDE has a Vim plugin. That plugin won't remove the distractions, fix the tab behaviour or clean up the UI. The controls are only a fraction of what makes Vim the editor it is.
This effect is compounded by the false belief in free will

Going to restaurants less often. Meals cooked at home are tasting better and can still be a great experience. I control what goes in to the dish, it’s fun to prepare and I get to try new things. Also, having groceries delivered is kinda’ nice.
Yeah, SUP bans don't do anything for the ocean. Investment in waste management solutions in low and middle income countries is far better for the environment, but most politicians are not terribly well informed.

AFAIK things like that (highway, OpenMP 4.0+, automatic vectorizers) are only good for vertical operations.

When the only thing you’re doing is billions of vertical operations, computing that thing on CPU is often a poor choice because GPUs are way faster at that, and way more power efficient too.

Therefore, when I optimize CPU-running things, that code is usually not a good fit for GPUs. Sometimes the data size is too small (PCIe latency gonna eat all the profit from GPU), sometimes too many branches, but most typical reason is horizontal operations.

An example is multiplying 6x24 by 24x1 matrices. A good approach is a loop with 12 iterations, in the loop body 2x _mm256_broadcast_sd, then _mm256_blend_pd (these 3 instructions are making 3 vectors [v1,v1,v1,v1], [v1,v1,v2,v2], [v2,v2,v2,v2] ), then 3x _mm256_fmadd_pd with memory source operands. Then after the loop add 12 values into 6 with shuffles and vector adds.
That was my first thought when I had seen news of the paper, but the paper had some data to suggest the negritos split off from other sapiens before the denisovan introgression.
How did you learn? Thanks.
Ask HN: Bad time to be an early employee?
I'm curious if, based on historical patterns, the excess money in VC right now is driving up valuations too fast, such that early employees coming in after ~ Series A/B are even more likely than usual to get screwed over on a risk-reward basis.

Does anyone have insight on this question? My intuition is that the smart thing to do right now is one of: (1) take large pay packages at more established tech companies, (2) negotiate substantial equity comp if you really want to join an early stage company, or (3) be a founder or founder-adjacent.

I've done a little research on student perception of programming in grades 5-9. One thing I found was that kids in 5th/6th grade (elementary school where I'm from) love programming. It's fun and engaging, and it feels like a game to them. If you look at their programming environments, they're using things like Logo, Blockly, and Scratch, which are intentionally designed for this demographic. There's color characters and graphics, interlocking blocks, programming models tailored for their level of cognitive development, etc. It all works very well.

But a strange thing happens around 7th-9th grade (middle school where I'm from). Suddenly perceptions about programming drop off a cliff. Students increasingly describe programming as "frustrating", "confusing", "boring", "scary" and generally not enjoyable. If you look at their programming tools, they're using VSCode, Javascript, Java, C++, Visual Studio, Xcode, Eclipse... tools meant for professional developers!

And the results are a lot of them just stop considering programming as a viable career path. They are presented with these tools and told these are what the pros use, and when these students hit roadblocks many conclude they don't have what it takes to become a professional developer. They get discouraged and become disengaged entirely in the idea of programming.

Now, as I said this is all just preliminary research in my local community. Maybe things are different elsewhere, but I think there's an opportunity for programming tools that target this middle school group, to help facilitate a transition between toys like Blockly and full-blown professional developer environments.

Per passenger, buses have far fewer tires. Bicycle tires wear down slower than car tires, and are smaller so there is less to wear anyway.

You'd need the deposit to be the price of buying a battery, because unlike a metal tank a high capacity lithium battery is pretty useful if you never use that company's charge facility again, but if the status quo is that the company only swaps their own serial numbered batteries within certain time frames, the whole notion of swapping an old one for a new one is meaningless. Sure, sometimes people will wreck a battery but return it anyway, like any lease business, but there's no way of using them as a general bad battery disposal service
Exactly. This (strict enforcement of terms and conditions and locking down user data) was the desired outcome of the actions taken, and will probably result in fewer leaks down the road which is fine with me. I’m actually glad they seem to be serious about it by even going after these “controversial” cases. I frankly don’t understand what people want them to do.
I definitely recognise risk appetite as a skill because it's something I know I lack. On the other hand, taking big risks - and having the kind of personality that takes them - seems likely give rise to 10 badly spent lives for each good one. Can't farm black swans when your n is 1 or something.
To me the real question is if a machine running MacOS existed in a Surface-like form factor that had touchscreen and pen support would it be better than the iPad at the tasks you just described.

I'm finding it harder and harder to justify that the divergence even needed to happen at all when more and more iPad users are just interacting with it via keyboard case and trackpad.

As someone who was involved in the Amiga scene I know how all this stuff works. Without that knowledge the site is very hard to use. It wouldn't be difficult to make an MP3 version of this site with an embedded player but I think the hosting costs might be difficult to pay for.
Actually yes, since some shops now only have paper bags which are expensive and break just by looking at them. If you forget to bring a bag from home you're in trouble, especially if your groceries are heavy and you're far from home - the bags are guaranteed to break. (This is Europe, so you're walking back, obviously)
My solution to this problem (for personal goals not collective) is spend time and build tools, abstractions and interfaces that make myself happy, to a point where when I'm building actual content I only interface with interfaces designed by myself.
That you call global IPv4 addresses to be a critical resource is extremely odd. If I go to prudential.com or to another insurer's website, the IP delivery addressing protocol doesn't affect competition.

A user doesn't really see any difference when traffic gets delivered over IPv6 instead of IPv4, so the scarcity of the global IPv4 space is meaningless compared to the incredibly vast usable size of the global IP space.
I use food delivery (grocery and meal) far more than I used to.

We really need a competitor for Instacart, BTW.
bad investors will eventually go broke in 7 years when they have no actual exits, but what’s insane is that bad investors aren’t going broke, the insanity is insanely profitable, presumably due to the macro climate, which makes them good investors (or selection bias but what’s the difference)

there are many pet horror stories of bird deaths from PTFE pans, typically from accidents, but occasionally from normal use. one may assume that it happens quite often without a canary in the kitchen so to speak, and thus goes unnoticed.

also, damaging the coating is known to lower the temperature at which PTFE will pyrolize. anecdotally i don’t think i’ve seen a single teflon pan in anyone’s home that didn’t have some damage unless it was nearly new.

most situations that people are exposed to PTFE fumes are certainly below the level that triggers acute illness, but i wouldn’t be surprised if it was very common to get enough exposure to contribute to cancer, but it would be very hard to verify or test for that specific cause.
Well they sell access to them so probably another way make the ‘ole hacker conference a little less Blackhat and a lot more Greenback.
It's not a bad thing that us men don't have to kill and die in large proportions just to keep the rest of the tribe going. Let's not overly romanticize an evolutionary trait useful for getting us throw ourselves into meat grinders. Let's enjoy our games and leave it at that. (Mine is tennis)
I know it may sound silly but I really like that they’re still sticking with the Toy Story characters!

Anarchists of that sort are only such until they acquire structural power, then they immediately become the new, organized, violently oppressive authoritarian power. It's why Antifa so resembles the fascism they claim to oppose. That exact switch happened repeatedly across the 20th century. An organized anarchist movement is something close to an oxymoron, a facade at best, for people lusting for the power to implement their own vision of how things should be (while using that particular appeal to lure followers). The people that were responsible for installing Lenin's famines and ultimately Stalin, would of course tell you they also meant well (akin to someone claiming they mean you no harm while they break your skull).

Because if "Firefox/100.0" reveals a bug, the bug may also trigger when other browsers introduce a similar change.
The excess money is also driving huge exits, so you're missing half of the picture.

These are all very different career paths that aren't even open to everyone who wants them. VC valuations probably aren't going to be the thing that moves the needle on any decision making.

This article is hard to read with the way it's formatted. It feels like just a string of random thoughts about climate change.

I was hoping it would talk more about the anxiety and hopelessness people feel due to climate change. Not only is our climate getting worse, people are getting more pessimistic about the future. With that comes anxiety but also apathy. At some point, you realize there's nothing to be done, you will die and the future will be horrible and you can't do anything about it. So just enjoy it while you can and come to terms with humanity's eventual demise.
Yeah, whoever thinks that adding 40 cents to your bill for forgetting your shopping bag is a "grave inconvenience" was raised a spoiled brat. Plain and simple. The bar for something to be a "grave inconvenience" isn't high if you've never known of real hardship, I guess.
The wear and tear is a function of weight and speed. It's also not linear.
This quantifies the nonsense of the San Francisco plastic straw ban, which was motivated by stopping plastic ocean emissions.

I'd say that for Rust, being accessible was always in the DNA of the language, at least since it went public. It totally counts as "trying to appeal to new people", as lots of people that didn't use languages like C or C++ use Rust. However I don't think it works for the "established language" part. I'd say Rust is a good example of what to do if you're starting a new language.
It gets better as more transactions are added to the end of the chain (in any later blocks). If fees are fixed at 0.1%, the average transaction only has to be buried by 1000 more average transactions. Most transactions are smaller than average, so they don't have to wait that long.

This also means that transactions are buried faster the more heavily the blockchain is used. For example, you'd only have to wait one block if there were 1000 transactions in it.

The only problem is if the double-spender is trying to double-spend 100 transactions at the same time...
Blaming failure on others or external factors doesn't lead to success. It leads to bitterness and resentment.

I think people set up those bots without even starting to think through the consecuences of doing so. There is nothing more hostile to users than a program that misbehaves, searching and finding that the problem was reported in 2017 and closed afterwards with the excuse of no activity for the last 6 months (or any other equally ridiculously short amount of time).

Bugs won't fix themselves due to not talking about them. If you want to close a report, have a human check if the reported misbehavior does still happen, and close the bug if not (or if no way to reproduce was found). Projects seem to forget that issue reports are reports on defects of their code, so they should be the first interested in fixing whatever is wrong.

I'm the kind of user who takes the time and effort to report bugs (and I'd say that already puts me on a small % of users). But when I see these "closed because of no activity", I just say "F.U., really" and go away.
I think the magnet charger was a bit thicker, which would explain the change.

I know the context is ocean pollution and my response is very anecdotal, and local watershed. Since the County & State put additional costs on plastic bags, the amount of them strewn all over the local parks, and the key creek in our area has dropped dramatically.

I still do see plastic bottles mainly from water, and aluminum cans both for soda and beer, but not much else.

This subculture exists everywhere. I play basketball and the most revered player is Kobe Bryant. He isn’t the best, but his work ethic and competitiveness was beyond all others. He’d probably be a jerk to play with, but most people are never in a position to do hard work to deliver something that they consider valuable.

Now what is valuable differs to each person. Basketball is just a sport. Chess just a game. A surgeon saves just one life at time. He helped write a new version of a browser. But to all of them, it’s important to them.
