Hey! I'm a PM at Stripe working on solving VAT/GST/sales tax pain points for our users. Would be great to connect and hear more about what you're looking for. Please do correct me if I'm wrong, but it sounds like your main pain point is around specifically handling the collection, and then remittance and filing of tax for all countries/jurisdictions you have nexus in? Or is it actually the difficulty with issuing customers compliant invoices across all countries you sell to (e.g. ensuring VAT ID is shown, language is local, etc.)?

Either way, would be great to connect -- kmoriarty@stripe.com
But, according to the article, the Connes conjecture applies to all infinite matrices. There's nothing strange about modifying the value of one entry in a matrix.
Titan has enough mass to keep a decent nitrogen based atmosphere as well. It is probably closest to Earth with the exception that methane is a water analogue on Titan.
I am not sure discovering is easier than inventing.
Some laptops support this too (eg business Thinkpads). Apple is a luxury brand and batteries are cheap to replace so it doesn't want to burden users to spend their precious cognitive capacity on battery management.
Intel also have solutions like ICH10 vs ICH10R. Today they also support it on some chipsets.

But you're 100% correct. I have friend who have few RAID controllers in his office just in case that one of it's servers fail. And all of them are purchased in same order to be from same batch.
Good thing the founders of modern science, mathematics, ethics and political theory didn't share the same opinion.
I'm not an expert on the measure, but the Wikipedia page on it [1] doesn't mention anything like that. It does say that the compensation depends on how much of an organisation's income has been lost, and that it (obviously) only applies as long as the employee is not fired.

Hardware RAID controllers always use ECC. Hardware RAID controllers haven't been using battery backed-up cache for the past decade, but supercapacitors and flash memory. So they provide better cache safety than any software RAID stack.

Also hardware RAID allows for a more consistent performance under heavy system load in my experience.
I have a passion for storage and I really liked this article.
I'm also very interested in the follow-up about ZFS.

Please note that the Author Jim Salter also has a nice podcast: https://techsnap.systems

My main gripe with the article is that the topic of latency seems underdeveloped.

The testing I've done using some of the parameters discussed on the article shows extreme, probably unrealistic latencies on the storage.
It's the same kind of activity - creation.

LiveView does two things in particular:

1. It includes live navigation, which updates the URL as you interact with the app. For example, if you try the live scaffold generator in Phoenix v1.5.0-rc.0, you will see that once you click the "New Post" modal, the URL changes to "/posts/new". So if users reconnect by any reason (poor connection, new deployment, etc), they will go back to the same page with the same modal.

2. For forms, we automatically submit the current form state on reconnections, allowing the server and client to sync up.

For complex applications, think a chat app or a game, then you have to persist messages, the game state, and what not on the server. But that would be necessary regardless if you are using LiveView or not.
This is what we're seeing in Italy at this point.
I disagree.

The web has been lawless since forever. Conventions have been established and reinforced by the big players to their profit. They now buy politicians like any other big, bad rent-seeker.

The total lack of sensible, restrained legislation is how we got a surveillance state and a turnkey fascist police-state, Stasi-like enforcement.

The lawless web never cared about that. Still doesn't. But yeah we used to "feel different" about that lawlessness. John Perry Barlow's big "world f.off and leave us" statement seems different now the NSA said sure, and bugged literally everyone because no consequences. With the assistance of google, Apple, ms because path of least resistance means what you think and you do not matter. At all. Yay lawless, huh?

> Physics do not allow you to simply modify the temperature of a point. Thermodynamics prevent that.

gotcha - in terms of the analogy, the temperature distribution cannot be any arbitrary distribution with a finite average (i.e. a finite L2 norm) --- including those pathological cases e.g. the temperature is 0 everywhere except at one point x where it takes the value 1 ---- no, the temperature distribution has to have some minimum smoothness structure, meaning that if you adjust the temperature at a single point, you have to also locally adjust the temperature of neighbouring points enough for it to make a difference to the overall global average temperature over the entire space.

for intuition, the animation on the wikipedia "heat equation" page is a good start: https://en.wikipedia.org/wiki/Heat_equation

When you plug initial conditions into the heat equation, over time it evolves to be smoother.
A note about RAID arrays: Yes it is true that drives have become bigger but not faster.

This causes RAID rebuilds to take longer. But I am not aware of any hard evidence that this means that this increases the risk of a failed rebuild.

There are more sectors that could be bad but you need to do a patrol read / scrub at least one month to detect them in advance.

I think there are a lot of scares about RAID of which I really wonder how much of it is rooted in anekdote and folklore.
I don't think it's that special. When there are large benefits to humans and no apparent downsides, humans will pollute as much as Earth capacity allows. Just like any other organism before.
If you only look at mathematics I think it's simply:
- Axioms are invented
- Conclusions are discovered

The magic part for me is that some axioms have been chosen so well that their conclusions are confirmed in the real world.
And that is a good thing. Surgical masks should be reserved for medical staff that needs it more than the regular John Doe.

I am all for the general public wearing facemasks to slow down the spread (slow down, not prevent) but there are plenty of clothed masks that help that while still allowing the surgical masks (and N95 masks) be worn by people that need it. (This was one of the annoyance when I was in Asia, me and about 40% were wearing reusable masks and everyone else was wearing the surgical masks)
Ridiculous hubris, to claim to speak on their behalf, to claim to know the opinion of so many and diverse minds, and in such a crude misdirection to boot.
Some 15% of people become “seriously” unwell, and require medical intervention such as oxygen. In a situation where the peak is hit unmitigated, these people will not get the medical care they need, and a lot of them will die.

>The same for negative numbers

Are you sure negative numbers are not "real" in the same way natural numbers are?

That would mean particles like electrons with a negative charge are not "real", too. And someone can argue that his negative bank balance is not "real".

As for complex numbers, I fail to see how they are less real than real numbers. Real numbers are points on the real axis, while complex numbers are points in R^2 plane. If we question the reality of real numbers, we can also question the reality of the plane.

Mr Euclid would frown to hear that.
Just for a second, try and imagine what world you would be living in without fossil fuels in the last 200 years. Would you have the computer or phone to write on? Would you have the internet to connect? Your house? Your food?

That's not to say it's not a good idea to change this, and to wean ourselves off fossil fuels. But to say this period was a period of human ignorance and "doped up"-ness is an extremely naive reading of human history.

I found this neat little repo that gives some tips for decluttering $HOME: https://github.com/vizs/declutter-home

I've employed some of them myself, managed to get the total number of files+dirs in $HOME down to around 18. Sadly I expect that number to rise as I install more programs.

Some dotfiles, like ~/.dbus cannot be changed because the path is hardcoded. Which makes me very sad

Ask HN: Building a site like Airbnb and Etsy with JAMStack?
Been reading lots of articles around JAMStack[0] (JavaScript, API's and Markup) and I'm pretty excited about it.

I am thinking about building an Airbnb or Etsy like site with JAMStack and planning to host this on Netlify but unsure about how to go about doing the API part of JAMStack.

Is there any pointers on this or I going about this the wrong way?

Humans aren't single cell organisms. We are self-aware organisms, arguably more intelligent than any other organism we ourselves have ever encountered. There are very apparent downsides to the benefits we are reaping, but for some reason we are incapable of acting as one in the interest of all, and instead seem to prioritize acting for ourselves, seemingly incapable of making the connection that the detriment of all will, in the end, also be the detriment of ourselves.

Wow, was that an IBM Deathstar? Two additional reasons for raid 6: 1. Fan failure on a hard disk pod causes damage to multiple drives simultaneously. 2. Many adjacent drives are connected via the same power cable which always has the potential to destroy drives in groups via over-voltage from a failing power supply.
They were certainly more protected than the almost naked ones I see right now which I can singlehandedly bend (but won't given the fire hazard). And not LiPol batteries too, which are super nasty in that regard: the more energy-dense the battery is, the more of a hazard.
Another big problem in this type of reporting is that majority of countries no longer test people who have mild symptoms or no symptoms. This means that there is bound to be many "unreported" cases as health authorities will not issue test you as they are overloaded.

It's not a big suprise. If you are following news from most countries, once it spread out health authorities stopped testing if you do not have significant symptoms and instead told people to stay home and isolate.

I'm very cautious with these type of studies. Lot of them are not clear in regards to how precise the test is, does it catch other coronaviruses as well, whether they did a follow up study to see if people developed symptoms or even how and when they picked their sample. All of these factors could radically impact the results.
The 15% looks implausible given the fatality rates mentioned here.

But I would expect a lot of the medical care to be scalable so unmitigated doesn't mean no medical care. We have been building field hospitals in the UK and US (though have barely used them so far), using hotels, etc. Providing oxygen should be fairly straightforward. I understood ventilators was the part that caused a serious scalability bottleneck.

Describing the era of fossil fuels as "doped up" is not a way of saying that the progress that was made was not good: it's a way of pointing out that it was unsustainable, and irresponsible. There's no reason to believe that computers or phones could not have existed in a different reality where fossil fuels were used in a more restricted manner, owing to their inherent dangers when over-used. Not only could the use have been restricted, we could also have compensated for the usage earlier, and made less irresponsible choices in how we perform our agriculture and industrial endeavors. The insight into climate change is not new, it's not something we're understanding just now. We just didn't care until now.

There's a reason people get hooked on drugs, it's a very pleasurable experience, while you're still using it.

I think I get your point and I‘m open to ideas which drive home your point in a more precise way. However, the main difference between concerning ourselves with whether or not mathematical objects exists vs music or start-up ideas is their place in building a foundation for understanding reality. Science has been a productive program for understanding reality. It happens to be underpinned by math. And as a result, we have encountered some pretty interesting relationships between what the math tells us and what we observe. For instance, neutrinos and black holes were known to exist mathematically before they were ever observed and measured “in reality”. It’s not clear to me that music and start-up ideas hold up to math when it comes to being a tool for understanding or describing our reality, or perception the rig. Math is somehow fundamental to many successful enterprises which seek to describe and explain reality. Therefore, it becomes the point of focus of much philosophical inquiry when seeking to understand reality. Hence the foundational question, do mathematical objects exist? And not, does music or blockchain kittens exist?
You think that art does not?

As this is referring to photons I'm reminded of a concept that comes from the use of Feynman diagrams to model interactions. I think this answers your question.

If you're calculating the probability that a photon goes from A to B you can calculate the probability (or more technically, the amplitude) that it goes straight there (this is the crude approximation), but you also have to account for the case where it went a bit off the way, hit another photon and then arrived at B (a slightly less crude approximation), and you can account for the path where the photon interacted with two other photons for a more accurate approximation, and with three other photons for an even more accurate approximation.

People stop the calculation from being infinitely complex because it appears that the probability of the cases with many interactions is incredibly unlikely. I guess the conjecture here was that if you have some error bound for the N interactions case, then the N+1 interactions case would have lower error. And that's been proven to not always be true.

I may be way off the mark, my knowledge of QED comes purely from watching Feynman and Susskind on YouTube.
but it is not in anything close to a growth in many senses.

email will be alive forever as far as I am concerned (just a few months ago a friend of mine managed to send an actual telegram) and probably will be the major player in enterprise communications. but it had sort of reached a plateau in term of functionality.

> Hardware RAID controllers always use ECC.

This is not what I was talking about. Of course they do. The problem is that data needs to somehow be transferred to the adapter first, and this alone adds a point of failure. Controller can (and too often do) have hardware and firmware bugs. The less components the lower chances for corruption.

> battery backed-up cache for the past decade, but supercapacitors and flash memory

No difference to software RAID there. For example ZeusRAM and Optane are used for this. Of course high endurance SLC flash with supercaps is also an option.

> Also hardware RAID allows for a more consistent performance under heavy system load in my experience.

I'd tend to count this subjective, but I'll grant you this one, it's at least plausible. I haven't encountered this issue, though – today's hardware has insane bandwidth. SW RAID can saturate 100 Gbps ethernet, how much more performance you really need?

Even if performance was slightly degraded, data integrity is more important.
