To be clear, the problem Bitcoin was designed to solve was not improving transaction throughput at scale. The problem Bitcoin aims to solve is all the trust involved in the fiat system we currently call money.

The current system requires us to trust that politicians and central bankers won't give in to the temptation to debase the currency by money printing out of thin air. As a result this exposes them to spend more public funds without the traditional constraint of having to raise taxes on the populace.

In short, Bitcoin was designed to offer an alternative monetary system to those who understand that the current fiat-based system is a scam and has been since the governments all moved off the gold standard. You may argue that this assumption is incorrect, but it is clear to me that Satoshi was solving the problem of trust in the creation of money.

Satoshi found a way to create digital value by minting a form of scarce digital money that does not rely on any government to give it value and makes it virtually impossible for any centralized actor to cheat the system and print more Bitcoin out of thin air.

Satoshi's vision was about honest money not high transaction throughput.

As for payment finality, I believe there is room in the market for multiple options and offering more options to the market is almost always good.

I agree that credit card transactions have their place in society and offer real and compelling benefits for consumers, but they are a nightmare in many ways for merchants. As a merchant, you cannot really rely on credit card payment receipts to be final for ~6 months if you must be certain there will be zero chargebacks. Try managing cashflow of a business if you have to be sure you will keep all the money you received via credit cards in the past 6 months.

For merchants who wish to have an option to receive payments with clear unambiguous and immutable fast final settlement of funds with no risk of chargebacks, there really is no alternative to Bitcoin in my opinion.

tl;dr Bitcoin offers the world an option to use honest money that cannot be manipulated. Can LMAX do that?

Firefox does support PWA. This is a browser extension for packaging and installing like a native app. Pwa is a web spec and it is very nice.
No.

To be more clear, you can mmap read only and just cast the pointer. You probably want the struct type to be "packed" unless you are intimately familiar with your compiler's struct padding behavior. Every C compiler I am aware of has some way to specify "packed", but it is admittedly not the most portable construct. In any event, if you ever doing memcpy calls then you still must worry about struct layout. So, the memcpy is not buying you anything.

You also do need to not exceed the size of the "file array", just like any array in C, but pre-mmap you usually open & fstat and the latter tells you the size of the file and sizeof(structType) tells you the size of the struct.

So, there is this implicit assumption that the underlying file is not shrunken between the said fstat and whenever you access it by virtual memory indirection. Outright file deletion would actually be ok - but truncating it would leave the kernel unable to satisfy the page fault.

Other code/entities shrinking files on you is really very far from what one usually means by "casting pointers and undefined behavior", though. It applies to any prog.lang. Even "safe Rust" doesn't block this problem.

Another similar aspect of your follow-up belief depends upon the OS/sys admin, really. For example, many Linux systems default to overcommitting memory. This means you could malloc and memcpy and still cast a (packed) struct, but if that were swapped out and then when the swap in starts to happen the system is low on real physical RAM you might segfault. Heuristics like out-of-memory killers are just that - heuristic not precise. If the data is on an actually persistent backing store, though, the kernel can always page that in. So, in some ways the mmap read only approach is safer than the alloc & copy approach (if you know that nothing will shrink the file on you post-fstat).

I lived in a forested area as a kid and the copper wire was always breaking for various reasons (falling branches, old deployment, temperature and humidity, etc). The ISP would always attempt to reduce the speed and leave it at that. It took a lot of effort as well as personally locating the breakage to get them to come and repair it properly (and it still took forever).

Apple sells billions of iPhones, all with the same hardware and OS. As a result it can afford to spend a lot of money on design.

I would also like to have it, but I can see how it could become a spam issue. Every garbage site on the planet would start pushing PWAs to get on a users home screen. It would be the same thing if notifications were reserved for PWA installs only and not in the browser.

That's one area where the app stores are pretty good. If you open the app store, you want to install apps. The same can't be said for a website.

I think the only way it would work really well is if the add to home screen / install button was prominent in the browser chrome and sites could trigger some effect if they can be installed as a PWA. For example, change from an inactive button to an active button.
And you don't seem to understand the magnitude of the productivity increase we've seen, even after the industrial revolution. And yet wages have not been keeping up with inflation, because this is all in servitude to wasteful diversity in consumer goods, setting lower prices (that only in some categories offset inflation) and a lot of bullshit jobs.

Sure, we need work, but with a different mode of production we wouldn't have stopped at 8 hours when reclaiming time for other things that can be equally or more productive, especially now.

I never liked the idea of using a watch as a bike computer. If all you want is to record the data for later use it's fine, but then just use whatever you already own - your phone, Apple Watch, etc. If you need to actually see the data while moving the wrist isn't a safe place to be directing your eyesight.

Right, it isn't the number that has value, it's what the number represents. The number of dollars in my bank account represents (in a roundabout way) debt the US government owes me. What does BTC represent? Most generously one could say it represents debts owed by the community, but since each member of the community can choose whether or not to honor that or to what extent it doesn't have any stability.
Despite not being in 5 eyes, Israel does get special treatment in the form of raw intelligence data from the US.

>The National Security Agency routinely shares raw intelligence data with Israel without first sifting it to remove information about US citizens, a top-secret document provided to the Guardian by whistleblower Edward Snowden reveals.

>According to the agreement, the intelligence being shared would not be filtered in advance by NSA analysts to remove US communications.

>While NSA documents tout the mutually beneficial relationship of Sigint sharing, another report, marked top secret and dated September 2007, states that the relationship, while central to US strategy, has become overwhelmingly one-sided in favor of Israel.

One thing I very much appreciate about the hacker news community are comments like this.

I didn’t read the article but clicked in of the comments “knowing” they be stuffed with Reddit like fury. “How dare they!”

I was wrong… Like usual.

It seems this community is significantly less jump-to-outrage prone than many others (eg. much of Reddit).

We still let the marketing-engineered clickbait headlines slip through (since they are the actual articles’ titles) - such as the title of this post.

But still, some of the least outrage-y responses on the internet.

Thank you Reonxi and thank you HN community.

That does not matter: either the solutions are unique or not, and ODEs (out of singular points) have a unique aolution for any set of initial conditions.

The sensitivity to initial conditions has nothing to do with regular ODEs and uniqueness.

I think this is common in places where they don't expect moisture to reach, but then things change and it gets there anyway.

If your POTS lines are down and the telecom company is telling you a "wet pulp repair" is underway, your phones are going to be down for a while because a bunch of paper-insulated cables need to be manually rewired because they got wet and corroded.

I found this interesting: http://etler.com/docs/bsp-archive/629/629-295-300_I3.pdf - guess it's standard practice to dry out the lines, wrap in cloth, put dessicant and then seal it.
> the system can produce explanations

That is the killer edge that rule-based systems can offer. You can question them about how they reached their conclusions; armed with the response, you can evaluate their reasoning and critique their conclusions.

Explanations aren't beyond the reach of ML systems in principle, AFAIAA, but I've yet to hear of any proposal about how one might construct a self-explaining ML system.

[Edit] I guess not being able to explain your reasoning might be considered an advantage, in some circumstances; if you can't show that a certain system is using defective reasoning (because it won't show you its reasoning), you can't show the system is defective, so it becomes harder to sue the manufacturer or relying party.

Been a while since I was in the chemistry game, but my guess is lattice structure and packing. Pure Si has relatively long bonds compared to carbon, so the intermolecular forces are a bit weaker. Apparently SiC has over 250 polymorphs, but the most common is the alpha.

... ok I'm reading about the material properties of SiC and it's insanely complex so I'm just going handwave and say that α-SiC has tighter packing with stronger bonds because of the alternating Si and C atoms.
Tuesday Carne is certainly a distracting pseudonym. Carne means meat in Spanish.

Replace it with Sausage to get an idea about how it affects my mind, and why you should be careful about what you draw attention to.

##The worker, Saturday Sausage, worked for a Google subcontractor called Modis in South Carolina. At a meeting Nov. 17, managers told her and others they had to work the holiday without any extra pay, Sausage says. I spoke with Sausage, and she said, “The only thing in my mind that I thought could be against the rules is that I said, ‘That’s bull**’.” Google employees’ Alphabet Workers Union is helping Sausage file paperwork with the feds.

Edit: I live in a third world country and not all Holidays are the same. Some are ALWAYS paid in full (workers earn twice as much if they work during the holiday, and thrice as much if the holiday was sunday free day), some are optional (the worker may ask the day off without pay) some are irrelevant (they aren't Holidays for the worker)
Holidays are appointed by a government as a way to gain popularity. They are costly for employers.

There is a middle ground between automation and full-blown programming languages.

In the past, this was represented by Visual Basic 6. For the use case presented - large organizations with considerable time spent in repetitive tasks - probably there has always been in the org a non-programmer who could hack together a VB6 program for the benefit of the colleagues. I remember even a person describing himself a programmer because he could use Excel (which can be considered close to the middle ground position in the automation<>programming languages spectrum).

There were/are lot of small tools around programmed in VB6, which are probably very low quality from an engineering perspective, but do the job.

As a matter of fact, I wonder why the VB6 spirit hasn't been carried to the present. As far as I read, Delphi's the closest, but I've never used it.

I know plenty of people who have chosen not to work forty hour weeks and make do with varying levels of money.

I have family who choose to be stay at home parents, I know working class people that own small businesses, like a caterer, and I know successful engineers who have negotiated part time roles, and contract work

These people all work, and they all get by. Working 40 hours a week is also a choice. I know people who work more than that too, because they enjoy their work (a shocking concept to the antiwork crowd I'm sure), and I've talked to gig workers who like the flexibility

These are just anecdotes but if it's the structure of the forty hour work week that you don't like, you just need some creativity, and maybe a willingness to make do with fewer material things, but you are NOT excused from the moral imperative to work if you are able bodied.

There are people who really can't work and if you can and choose not to do so, you are hurting society's ability to help those people.
I love the innocuous application of enabling just the Debian package management behind such draconian firewalls.

Not just Venus, the whole cost of cooling chips and cost of raw material extra's like heat-sinks could be reduced and that in itself would make a huge saving thru volume. Some IC'c on this type of silicon wouldn't need that extra cooling cost and that is were the big saving will come in, even with the extra cost of the IC's factored in.

That and if you can remove all cooling, not just cost savings, but in some cases being able to remove active cooling and less moving parts is always an engineering win win.

When it comes to censorship, I think at best it doesn't really matter why, and at worst it's fair to assume mal intent, even if it's not obvious or provable. Otherwise (and without an affirmative reason), why hide it?

That's the nature of censorship.

But especially so when the "alpha testing" is specifically done on videos of the new White House administration.

Unless you're questioning whether removing the downvotes qualifies as censorship at all. Which I would find a little weird.

What hypothetical "pure" intentions would you suggest are possibilities?
I should check what's the status with Atomics.wait on Chrome, currently it seems to work fine under both Node and Deno.

I'll test out the regex thing in the following days as I need it for that exact use case, I just assumed killing the web worker would... work, hopefully that's the case otherwise I'm back to square 0 :D

Edit: MDN says: "The terminate() method of the Worker interface immediately terminates the Worker. This does not offer the worker an opportunity to finish its operations; it is stopped at once." so if that's not the case either the engine is wrong or the docs are wrong.

Managed grazing within forested land is an option. Our forests have become too dense in many areas due to overly aggressive fire management.

That would allow survival for a few hours or days at most I imagine.

I'm sure it's possible to build something that could operate at these kinds of temperatures permanently, but it would probably need an RTG (nuclear battery) and may be hard to test it on earth and also allow for thermal expansion and shrinkage (hard to keep the probe at this temperature for the entirety of travel to Venus). We'd also need to design lubricants for gears, cameras and sensors that can tolerate a wide range of temperatures, etc.

The upside of all this is that there are probably legit industrial use cases here on earth for electronics that are resilient in extreme temperature ranges, and in satellites as well.
Not local, but small and competitive was nice. Electronics were so much more fun twenty years ago. Nowadays a company is a bold risk-taker if their glass sandwich has an extra button on top.
I think SiC devices will be a way station on the road to diamond devices for extreme environments. GaN devices will be the next after SiC, then on to diamond.

I've seen a diamond FET operating at 700°C. Devices like that could use the Venusian atmosphere for cooling.

Show HN: I wrote a book about using Lambda with Go
Hi HN!

During the last few years, I worked on a few applications built with Go, running on AWS Lambda.

As I got to know the platform better, I started to find Go & Lambda to be a really productive combination. The applications were fast, and they ended up being much cheaper to run than what my team & I had built before. It’s probably not the best platform for _every_ application, but I was surprised at how much of our workload worked well on it.

As we brought new engineers on to our team and helped them get up to speed with the stack, I found that we were covering a lot of the same topics over and over — especially things like performance, testing and monitoring. Since this knowledge turned out to be very useful for our team, I decided to gather it into a book that will hopefully also be useful to others.

This is my first time putting something like this together, so I'm grateful for any feedback!

The book is at: https://kevinmcconnell.gumroad.com/l/lambda-go-book/hn (with HN discount ;))

There's also a link on that page to a free sample that you can download without registering.

Thanks!

Cheers,
Kevin
I only got paid extra when I worked in IT for the government. Not sure why people would expect extra pay though in a non-unionized, private sector job if it wasn’t part of the employment contract.
What is the apparent connection between having purple hair and being disgruntled at work? If you look at the Alphabet Workers Union "who we are" page the rate of artificially dyed hair is like 5 orders of magnitude above the background rate. Is it cause or effect? Does the dye poison your brain?
If your grand insight is that charging infrastructure is still being built out then that's no insight at all. New stations are going in daily.

Look, if you're too afraid to think about EVs now then the best advice is not to worry about it. Live in the happy tail as a late adopter. By then all the decisions will have been made for you and you won't have to think.
This gave me hope when I saw it yesterday morning. For once, some news that sounded like something the heros of a cyberpunk novel would have been doing, instead of another corporation being even more horrible than a supposedly-parodic fictional corporation with a technology to abuse for profit.
Contrast to Apple, which uses a fully functional model: https://hbr.org/2020/11/how-apple-is-organized-for-innovatio...

I find this evolution fascinating. It makes sense to me that the GM model worked for so long. If much of a company's advantages were cultural, you could put together teams that could out-compete startups within a large organization. Procter and Gamble needs to enter new markets with new products to grow -- there's only so big a market for soap or razors or drills.

But lots of tech companies today have a significant scale advantage. Google ads is most of their revenue; Netflix has a single product. Functional expertise that drives a 2% gain across the entire business is possible and valuable.

So ... why does Twitter want to go to a GM model? Are they watching Meta have success diversifying from Facebook? Or is there something else?
I'd like to just see them distribute their actual profits instead of being allowed to "hoard" it. That would also go a long way in fixing the stock markets supposed "growth by any means" criticism. I'd argue that the hoarded profits are one of the main drivers of all these acquisitions that reduce competition and lead to consolidation.
Trees are supposed to burn but in patches and not en masse due to previous fires in adjoining areas. This is especially true in the area you left. The natural state of the area should be a variety of forest in different levels of maturity which helps contain the fires that do occur in the most mature and overgrown areas. The less mature forest or previous burn scars act as natural fire breaks.
No I’m saying that “I will have a place to charge overnight every night” is unfeasible.

Whether that’s good enough depends on what you’re doing and your car’s range.

edit: I remember renting a Tesla once in San Francisco and when we got home with very low charge after a fun trip (on which we had to visit a random small town for an hour just to top up a little), we couldn’t find a place to charge. Everything the Tesla map showed was a locked garage with no public access. After a frustrating hour of searching and the car increasingly panicking at us about permanent damage, we resorted to going back to the only place we knew for sure it could charge – back where we rented it from.

We then ubered home for $20 and back to the Tesla next morning for another $20 (we rented for 3 days).

It was easily one of the frustratingest cars I ever rented.
> China's tech companies, supported and subsidized by the government, will take over.

This is going to be unlikely, when the Chinese government is actively kneecapping its own big techs.

Data is going to be regulated like money, and not everyone is going to have the privilege to operate data on one's soil moving forward. No western companies could do in China, or vice versa.

> US/Europe will be unable to ban these services entirely because their citizens depend on them too much.

They can just ask it to sell, which was happening to TikTok, or setting up joint venture capital. They are many ways to do such things, government can make you bleed if they want to.
