The article mentions the content is 500mg of oxalic acid / 100g and says the deadly dose is at 15 - 30g. That makes for 3-6kg of rhubarb leaves. Quite a serving, if you ask me.

In the original British understatement:

> Since a lethal dose of oxalic acid is somewhere between 15 and 30 grams, you’d have to eat several pounds of rhubarb leaves at a sitting to reach a toxic oxalic acid level, which is a lot more rhubarb leaves than most people care to consume.

The kinetic energy of a body, in purely Newtonian mechanics, is Ec = (m × v²) / 2. Since energy is measured in J, mass in kg, and speed in m/s, it follows nicely that J = kg × m² / s². Or, we can also take the potential energy of a body at some height h above the Earth: Ep = m × h × g, where g is the gravitational acceleration, ~9.8m/s², and we get the same units.

It's really not in any way surprising - this is basically the definition of the Joule. The link between units of kinetic energy and units of thermal energy is actually more surprising.

The surprising thing about E=mc² is that it gives a definition of energy for a completely stationary body outside any external field.

One way to look at it is actually that this is simply the kinetic energy of the body, and that all "stationary" bodies are in fact moving with speed c on the t coordinate in 4D space-time ("a body which is not moving in space at all is moving with speed c towards the future"). [Note that of course speeds are all relative to some reference frame.]

Note that when most people were poorly educated, those able and motivated to self-educate would stand out more.

So could it be that the level necessary be considered a 'genius' has increased over time, as a result of most people being so much better educated than in the past? Effectively, narrowing the gap between them and those considered genius-level?

Chrome wants to get rid of fingerprinting, and has for many years (see the entire Privacy Sandbox effort). But they cannot do it unilaterally, they need to identify the legit use cases and design + implement new privacy-preserving technologies to meet those use cases. (Yes, yes, we all know Apple and Firefox have been able to such things unilaterally. But as we've seen by the different reception from Apple having shipped remote integrity attestations in prod for a year to Chrome just proposing it, the rules aren't the same for all browsers.)

Fraud prevention/anti-abuse is both an extensive use case for fingerprinting and the most obviously legitimate one. If we demand that browsers close off all the fingerprinting loopholes (it's a great goal!) but don't allow a replacement, the web will be mostly dead as a platform in 10 years. All economic activity will move to native apps on walled garden platforms that are able to provide effective anti-fraud mechanisms.

At my childrens school, as work is often online they allow them to go ahead in modules. The teacher mist open it for them though to have some control.

Some people in year 7 are doing year 9 work. Great for challenging them but it will be curious where this goes as you might get some people finishing all of highschool classes for a particular subject quite early and need to keep educating and challenging them.

For english they have a program where you can finish your end of school exams for this subject the year early, freeing time for other subjects.

Physical limits don't matter much when economic limits (transistor cost) are reached much earlier. What matters is not transistors per chip area (Moore's law) but FLOP/s per chip cost. Also FLOP per chip power draw.

I haven't read the article yet, but I've known that functions are (infinite) vectors for some years.

However, there's something that has been bothering me: most of my understanding of linear algebra comes from 2D and 3D spaces, and then in different context of machine learning, datasets that have from tens to even millions of dimensions.

In the former, geometric context, the connection between the dimensions are clear: they are orthogonal, but conceptually exactly similar. They are just a 90 degree rotation away from each other.

On the other hand, in ML datasets some dimensions are conceptually very similar, and some are totally different. Some are correlated (nearby pixels of an image), some are not, but represent the same unit of quality, and some represent totally different, unrelated things. And as we go toward the mid-layer representations, it becomes very unclear and fuzzy what they represent.

In the case of functions, there's usually a clear connection between the dimensions: they are of the same unit (the domain and the image (the outputs and inputs) of the function are sets, and those tend to be made of similar-ish – or same type of – things, at least in well-behaved math). And there's often a similarity metric between the elements of the sets.

The 2D/3D linear algebra that I know doesn't bother with the "connectedness" of the input dimensions; it only cares the connections from the inputs to the outputs. But surely there is a lot of interesting math that is concerned with the connectedness of the input and output spaces themselves, in context of there still existing a mapping between the input and output. What is that field of math called? What are the interesting results, theorems and such? I love learning more so I'm kind of just looking for some pointers/keywords.

Yes I've tried both the XReal Air and the Viture. I like them. The XReal pinch my head which is really fucking annoying which is the main reason I ended up going for the Viture. The Viture are crystal clear apart from the very edges which are a bit blurry. From comments I've read on reddit, I believe this might be due to mild astigmatism so I'm going to the opticians soon to get my prescription so I can get the custom lenses and see if that fixes it. I think this is the better way forward if you have myopia/astigmatism rather than using the myopia dials on the top of the glasses, I think I have very mild myopia in one eye (like -0.5 or something) so I played around with the dials and you can dial it in with a bit of trial an error but it is an annoying process trying to get it right - they really should have done it so that when you change the dial it shows you what level you're changing it to on the screen (e.g -0.25, -0.5, -0.75 whilst you're turning) which would have made it far easier. Other than that I think they're great. If you want more detail I did a bit of a longer post here where I go into a more detailed comparison of why I went with the Viture over the XReal:

The problem with the IPC approach isn't error handling - in the error case a good string is usually fine. The problem is with parsing the output of the sub process. A library can return structured data. Parsing always has the risk of format change or quickly gets very heavyweight. Both in the syntax of the output and the parsing routines. It is another good example of the SVN system, that their commands usually have the "xml" option which creates structured output in xml format. So you can use standard parsers to get robust output.
This is also one thing I like about powershell, that commands can produce and pass objects instead of just writing to stdout.
Considering I'm someone who knows very little about hardware and almost nothing about its manufacturing process, I have a question.

I assume what this article means is that only 55% of the produced chips in this process node are considered completely working, which I suppose it means that these 55% of chips are the ones who must have passed all the tests.

So that leaves 45% of chips where at least one defect was found. But here's my question: with Apple's M2 Ultra chip having 134 billion transistors, do the tests really cover all of the non-redundant transistors, which I assume are a substantial portion of them? And also, even for those transistors that are tested, how reliable are these tests in detecting defects?

And assuming that not all transistors are tested, given that 45% is such a high failure rate, isn't there a very high chance that even those chips that passed all the tests also contain plenty of bad transistors, but they simply weren't tested (or even if they were tested, the tests may have not reliably detected a fault)?

Even considering that these chips contain some redundancy / fault tolerance, it just seems kind of amazing to me that they are as reliable as they are given all the unknown faults that they might have (and I'm only focusing on the manufacturing process, but some of the same reasoning also applies to the design).

There’s not much you can do since adding chalk (which used to be common for both spinach and rhubarb) just creates the oxalate in the pan instead of your body and you can’t remove it.

I applaud Colin's (Tarsnap Founder) attitude. Sure it could be priced better. Sure it could make much, much more than it currently does. But I dislike the notion that every software company needs to optimize for the same things. Tarsnap is a service that I am sure makes comfortable amount of money for its founder and has remained faithful to its initial audience. Why does anything other than that matters? Yes, some things Patrick points out are indeed low-hanging fruits, but I believe it's a conscious decision to completely ignore all the "optimisation" aspects.

Tarsnap doesn't even have any tracker on its homepage. Tarsnap has had the same basic pricing structure for the past ten years. It does one thing and does it well. I hate the pursuit of growth and everything that comes as a result: bloat, shiny landing pages, a/b testing, conversation rate optimisation.

I love that picture as it shows the difference in size and how chromium just sucks everything in, but somehow I miss the fallen Konqi (KDE mascot) in it. Konqueror (the KDE Browser) with KHTML was the origin of Webkit and therefore Chromium, but due to the vast improvements Apple (and later Google) made to the code base, KHTML and Konqueror became obsolete.

Nowadays, KDE users better use Firefox.

> That was because of competition. The cost per transistor actually went down by a lot.

I'm not talking about the marginal cost to make the device, I'm talking about the R&D and capital expenditure to develop and build the machines for the next node.

You can be reductive and say it always boils down to competition, but then you would also say that ultimately shrinking will end when it can no longer compete with mature nodes. Competition in both cases. So I'm not sure what exactly that's getting at.

> If it soon goes up significantly, it will stop to make economic sense to increase transistor density any further. Why pay the same amount of money for a less powerful chip?

That's not strictly true, performance of a transistor still has value. Companies like Apple pay premiums to get in early on leading edge nodes, more per device than the mature nodes they move from.

Is there any indication that it’s possible to build subatomic size transistors? Last I checked the data, transistors are already only a few atoms in size (silicon and carbon atoms are somewhere in the 0.3nm range), and it was a widely held opinion that it would stop at that if not much sooner. That would keep Moore’s law alive for a bit longer at best but the end does seem in sight.

Even considering all of that the economics seem to have already stagnated in cost for performance.[1]

It's good that you can do this, but most people prefer the default experience instead of fiddling with customizations to make it more special. And yes, fiddling and customizing is cool, when you have time.

So between the Apple automatic and Gnome "pick customizations" I know which one I prefer (and yes Apple does have extensions, settings, etc). Yes, there won't be a perfect solution and sometimes you kinda miss some minor thing but it is minor.

For example, looking at: https://extensions.gnome.org/#page=2 there's Date and Time formatter (you can do that in Apple) and "Sound Input & Output Device Chooser" which you can do by going in settings in Apple - but it doesn't matter most of the time because the out of box experience works almost perfectly
All fair points, and Patrick acknowledged this at the time - and in the previous HN thread back in 2014. I remember it was a good one.

The detail that really pets me backwards is the whole "if you're here, you already know what this is for and how to use it" vibe. It's not just Tarsnap; many aspects of the OSS world uphold this most unfortunate tradition. I believe with all of my heart that it is unnecessarily hostile and antisocial.

Many of the founders and teams I've mentored over the years have experienced me spending a large amount of time and effort explaining the importance of clearly stating why a thing exists and why you should use it; how it works and how it will not create additional unknown risks; what tools it is intended to replace... as the barest civil minimum.

This is just my opinion, but it's a hill I'd die on if necessary.
