the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it.

A space consisting uniquely of one point is thus zero dimensional since you don't need any number to figure out how to locate such point; by definition such space contains only one point.

Dimensionality is a property of a space, not of an object.

If you draw a curve on a piece of paper, is the curve 1d or 2d?

If depends on the space you choose to ask this question in! And for that question, there are two interesting spaces: the paper (where you view each point as having a position in the paper and two curves with a different shape would be very different curves) and the curve itself (where points along the curve are identified by the "linear" distance from one of the edges). There are practical examples, e.g. when you have an accident in a highway chances are it's easier to report your location using the km/mile position as reported on signs placed at regular intervals along the road (rather than your longitude/latitude).

W.r.t the "void": I'm not sure exactly what do you mean. I can think of two meanings of the word: the parts of a space that are empty, i.e. devoid of some "things"; or a space without any state at all, a pure "nothingness" without any property nor anything in it that could have any property.

If you're thinking about the first meaning of "void", then consider what we said earlier about dimensionality being a property of a space not of a location within that space. If you view each point of this void independently, then each of such positions is a zero dimensional point. But you can also say that there is a spherical region of empty space (and call it a void) and such space would be a 3d space (consisting of void).
The cozying up to Gilead was bad enough. The NIH COVID-19 response group has way too many people reporting financial ties to Gilead. Then you find out the Gilead CFO left to work for the Alphabet/Google/YouTube corporate board on March 1 2020, and suddenly the unprecedented ban on videos that threaten Gilead's potential to make many billions of dollars, as long as HCQ is banned, makes inexorable sense.

When I was in university, if you forgot your slide rule at an exam they kindly had a supply of log tables you could pick up from the proctor.
One of the nicest things about a slide rule is, you can easily see the sensitivity of the result to variations of your last input.

With a calculator, you get precision. With a slide rule, you get a value and its sensitivity.
Apple learned (prior to 16”) that a large number of customers want to run huge VMs, load massive AI models and have faster imaging performance that comes with higher memory limits. I don’t think they are going to ever want to introduce another Prosumer machine that people slam publicly that hard again, plus they can’t exactly use the iPad Pro memory controller so they are designing a new one anyway.
I may well be misunderstanding a definition of science, but no I wasn't confusing it with "good".

I don't know what the best definition of science is, but here's the first one Google suggests:

> "the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment."

Can you explain what excludes the studying of human behaviour or mental health from how you define "science"?
Alas! No specific mention of the circular slide rule [0].

REON Pocket Working in USA
Ignoring US web content about, these folks never tried REON POCKET, aka fake news. Anyone who tried to get REON POCKET ) working in the USA is in for a very rude surprise. Sony has limited REON to Japan only. In iOS your Apple ID is associated with Japan, with a Japan address and phone! Similar challenges with Android. Further Sony requires a Japan IP address.
I decided to throw down the gauntlet with Sony, and see if I could make it work (I did). Skype gives a Japan phone number for $5, and google search can find a real Japan address (ex: Tokyo FedEx). Also used Tunnel Bear to VPN to Tokyo, which tricked app stores and Sony upgrade servers into thinking I was in Japan. App store REON POCKET (using VPN) worked. I had trouble with Android, but that could have been because it was a tablet. Since Apple will not let you change your iPhone REGION code without a serious penalty. I used an old iPod Touch that I use for app development. So it requires you to use a very tight fitting shirt (Asian sizing is different).
At the point where I’m on your front end server, I’m not stealing your password, I’m stealing your auth token. I don’t care much about your password once I can harvest auth tokens en masse.

Don’t forget about the main point: hashing and salting on the client side does not replace doing the same thing on the server side.
But baby humans tend to associate phonetic symbols (spoken words) to what they are seeing, and the learning method is very different. Their context is much broader, helped by multiple senses. NLP is extremely contextless compared to what humans do. You can't talk about "more data" so easily.

One under-appreciated aspect of a slide rule, is for instantly seeing fraction reductions at a glance. For example, lets say I want to find out what aspect ratio a given screen resolution is at. I can set that resolution as a ratio on the slide rule's C/D scales (i.e., 1680x1050 becomes 1.68 one C, lined up with 1.05 on D. Then I glance over, and see immediately that is 16 x 10 resolution.) If the value goes off the scales, look up to the CF/DF scales.

This is also great when you have a bunch of resistors and capacitors, and you need to build a circuit where the two are at a particular ratio. Set the ratio you want, then you can take whatever resistor you have, and see if you have a cap that is "close enough" to what you need.

Timing the market is doable I'd say. Not all the time and not by everyone but it is completely doable. Sometimes you will buy too late or sell too early but even buying the dips is timing the market. If you partook in some stocks, more so than otherwise, during the March lows you were also timing the market.
As a software developer I imagine the brain not as some separated layers but as a huge collection of routines/procedures, for this or that (including procedure for understanding numbers), interconnected with a spaghetti code of links. Many of these processes specialise in making decisions and calling other processes. One specialised procedure is called the consciousness, it is blind to the rest of the processes and it is tricked into believing that it does all the calculations while it merely reads the results from other processes.

Also, I highly recommend the book The Language Instinct by Steven Pinker.

Does this mean a real possibility for user-defined, community 5G networks? If so, that could usher in a new age of mesh networks to democratize the long-range wireless network space. If the hardware is cheap and a protocol were used that's anonymous and encrypted by default, this could be a game changer.

From an idealistic newbie's perspective, I imagine the possibility of users buying routers with this tech, plugging them into their fiber or copper connection, and creating or expanding an existing 5G meshnet + a home net. Maybe it could drastically drop costs for 5G network operators as they wouldn't need to put up extra receivers anywhere. They could simply offload that burden to the consumer. Most routers are lent out anyway, so not only would they make money, consumers wouldn't need to worry about which operator they chose because they'd all be in the same meshnet anyway.

But eh... I'm sure there's some big thing I'm missing besides human greed.

I don't think cutting a small hole in between studs requires "architectural design" and "electric load calculations" really means "it uses this many watts". There is nothing typical about someone needing a year to do something relatively simple. Most restrictions probably just say that the condenser coils can't be on the side that faces a street and maybe that it has to be on a dedicated circuit.
Very cool! I built something similar for patent application about 5 years ago for proximity image encryption. Idea was that image was split into X number of encrypted pieces each still being a valid image (disorted or something custom). If you wanted to see the image again, you had to be in close proximity to other parties that have these parts. BLE beacon served as the proximity for the prototype.

We don't really have the concept of "common carrier" in the UK. So, an ISP that carries images of child sexual abuse (maybe in Usenet newsgroups) is potentially liable for carrying those images.

IWF was set up to allow ISPs to find and remove that content without being criminalised for taking action on it, and then to safe-guard the children who were in those images and videos.

Expansion into computer-generated imagery follows from changes in UK law that made computer generated images of child sexual exploitation, (and also images involving sex with corpses, realistic depictions of rape, and realistic depictions of acts that harm genitals) illegal.

> In 1996 the Metropolitan Police notified the Internet Service Providers Association (ISPA) that some newsgroup content being carried by UK internet service providers (ISPs) were indecent images of children. The police believed this may have constituted a publication offence under the Protection of Children Act 1978 (England and Wales) by the ISPs. Efforts were then made to find a way to combat the hosting of such content in the UK whilst protecting the internet industry from being held criminally liable for providing access to the content.

> Following discussions between the former Department of Trade and Industry (DTI), the Home Office, the Metropolitan Police, some ISPs and the Safety Net Foundation (formed by the Dawe Charitable Trust) an R3 Safety Net Agreement regarding rating, reporting and responsibility was created by ISPA, the London Internet Exchange (LINX) and the Safety Net Foundation. A key outcome of the Agreement was the formation of the Internet Watch Foundation (IWF).

> The IWF was established to fulfil an independent role in receiving, assessing and tracing public complaints about child sexual abuse content on the internet and to support the development of website rating systems. Since we were set up in 1996 we have been operating a Hotline service for the public to report potentially criminal content and we have been issuing ‘takedown notices’ to UK ISPs in partnership with the police so they can remove the content.

> The Hotline was formally launched in December 1996 to combat child sexual abuse images and criminally obscene adult content hosted in the UK. Since then we have been continually improving our practices and developing unique services for the internet industry to help them make their services safer for their users.

So I think that's a fair point, at the same time I don't think 'race' is quite a silly thing, just not a hugely important thing.

If race is silly, then is BLM a silly concept?

We could say the same thing about 'silly culture' or 'silly language' or 'silly attitudes' or 'silly politics' ... so that we can just all focus on the truly important things like our 'iPhones'.

At very least it's history, and interesting on that level, more controversially, it's part of our identities at least in a broad sense.

Silicon is just slang to describe chips without referring to their actual model names and specs (yet) —someone in Marketing (Phil?) saw how the religious faithful began to worship the “A” series chips in the blogosphere and capitalized the S in silicon during this interim period. Brilliant!

I'm also an index fund skeptic mainly because it's now such a convention that taxi drivers and shoeshine boys will tell you that's where you should put your money. People used to say the same things about investing in real estate and many other things and for a time in history those things were demonstrably the best investment long term, until it wasn't. It looks like now is that time again for the stock market to look good. It still doesn't mean it's a bad investment either and no one will blame you if you suffer with everyone else when it goes wrong. However, it's also never worth putting all your money into unless you can afford to ride through a slump that could last well over a decade.
Part of the point of the current US vetting process is to ensure judges have the same beliefs as the current party platform. Even if you put the political philosophy of judges on some sort of pedestal (which you probably shouldn't) they don't get appointed unless they have the "correct" politics.

> If the GPU gives you some nice fancy shading, but your game works fine without it, then GGP's suggestion to "just make it fail" is of course silly.

Not really, that's actually the point being made: if you try to use the GPU with your fancy shaders, you'd rather have it fail noisily so that you can explicitly fallback to the CPU implementation without your fancy shaders, than the library silently falling back to rendering everything (including your expensive shaders) on the CPU.
There is whole bunch of reasons and that bunch of reasons has name IoT.

I mean that security of such utility units would be roughly what we already see with current breed of IoT devices. To keep some kind of quality level of such devices there would have to be one big company that produces them, which does not solve the problem. If you look at IoT devices manufacturers now there is so much crap floating around because there are so many of them.

My favorite company positions are partner agnostic. I’m not sure why but I somehow morally agree more with a company who provides their service to a variety of partners and doesn’t have a preferred vendor.

I knew someone that had an HOA rule against window air conditioners. His solution was to keep the window-mount unit inside his bedroom, with the back end (that normally sticks outside the house) enclosed in a box. That box had an intake and exhaust fan, with flexible duct work that routed to a piece of plywood stuck up in the window. From the outside, you just see the screen with the plywood on the other side. But it worked about as effectively as if the whole unit was mounted in the window.
Not sure I follow the logic.

> ... cloud apps depend on the service continuing to be available: if the service is unavailable, you cannot use the software, and you can no longer access your data created with that software. This means you are betting that the creators of the software will continue supporting it for a long time — at least as long as you care about the data. Although there does not seem to be a great danger of Google shutting down Google Docs anytime soon, popular products (e.g. Google Reader) do sometimes get shutdown or lose data, so we know to be careful.

Plus, the value of the cloud app is not just your data, but the network effects. Like, if you've emailed links to a GDocs document, and 5 years later you decide to move to another service, those GDocs links will 404, regardless of whether you've transferred all of your data to the new service.

To me the fascinating part is that with the ransom payment they received the decrypt key as well as the security system patches needed to protect the system.

I recall a story here on HN, some days ago. A company was attacked, then the attackers waited some months to make sure that all backups had been contaminated, then they struck.

So victims can only make sure that they have a malware checker that finds the culprit, then do fresh installs, then check each file before it's restored from backup. Sounds like a crazy amount of work.

Most every study we have shows a decrease in real sexual activity linked to an increase in available pornography. We have no reason to believe child pornography would be any different. This was of course irrelevant as we had a duty to protect real people.

Now we are in a strange situation where effectively; 'virtue signaling' maybe causing child abuse.
