The idea is that what 1/x is is intuitively simple enough, so we should have some standard terminology for it.

And saying left and right limits is -infinity or +infinity really also isn't that weird. I'm pretty sure other metric spaces can be likewise extended and end up with similar algebraic laws as the "extended real numbers". Again this isn't very profound, but is good for education and efficient communication, and so should be perused.

Finally, it's interesting that measure spaces with infinite measure is already a thing that people. I would like to see more connections with metric and measure spaces; e.g. we can have an n-point metric which is defined using the measure of the (n-1)-simplex. Just as regular metric spaces have a "triangle inequality", 3-point metric spaces should have a "tetrahedron inequality", and n-point metric spaces should have a "(n-1)-simplex inequality". Again, this is not profound, but good for communication, and connections between definitions help one compress everything for better mental storage.
Disabling it in Windows on Pro and Home is not sufficient. Registry changes are the only way to completely turn off activity history. It is really disingenuous of MS to suggest you have the option to disable any of the telemetry. The wording they should use is "reduce". Turning everything off via the privacy controls in Windows will significantly reduce how chatty the box is.

DNS filtering does not work any more as far as I can see. It appears they have wised up and are consolidating endpoints so that you can't block it that way any more.
This concept was widely deployed in certain regions with "storage heaters": very heavy (~40 Kg) electric heaters that would accumulate heat during the night when electricity is cheap and release it throughout the day.

They felt out of fashion because apparently they were hard to use as you cannot control how the heat is released. Charge them too much and you will have to open windows the next day wasting energy, charge them too little and you will have to turn them on during the day when the electricity is expensive.
price. they could sell the iMac pro for $$$ while the 'budget' version used HDD.
The "best" CPU that comes in that lineup is the Intel Core i7-7Y75.

I have a GPD P2 Max[0] which also has 16GiB of ram and a Intel Core m3-8100Y...

Not to brag but my CPU does seem to bench higher[1][2], and for me it can be painfully slow at times.. Though perhaps the OS is doing me no favours (Sway+Arch/Chromium)

HN is an Apple fan club.

Most people here are from Silicon Valley and Apple is the biggest employer over there.

Try to badmouth Samsung in a Korean sub and you get the same treatment.
Yeah, using lambdas as nested functions is pretty common.
Has this site had any UX/UI updates in years? I've always assumed assumed it's "done" and we just have to deal with what it is. I come here less and less because of how feature-free and bad the UX is. Everything is a click to another page, then click back to what you were doing. Why do I need to go to another page to favorite an article? It causes me to hardly use the feature because it's such an interruption.

Can we make the beautiful C syntax insufferable? Yes sure just leave it to the committee.
But I thought we were talking about national security? Why did it suddenly turn into privacy and data control?

Privacy is a legit angle, but why focus on Tiktok alone? Talk about privacy law reforms so that Twitter and Facebook are also included.
I largely agree. I wonder whether people should have to pay (in points?) to comment, this would demotivate people who have just have nothing of value to contribute and those who are simply trying to gain points because it would be an investment. Is that a bad idea?
I'm one of those people. I really struggled with my undergrad linear algebra courses. It was taught in a very abstract way with no suggestion ever that any of this had useful applications. I passed (barely) and was glad to be free of it.

Years later when I got into graphics programming I found myself dealing with linear algebra concepts but this time it made much more sense to me. Being able to apply the ideas to real problems with visual solutions made all the difference.
You're using the word Capitalism as though it's representative of an ideology. "Capitalism" is a term created by Marxists to describe a system that allows people to freely exchange with one another without force. No one is going to grow your food or build you a house without compensation. That's why Marxism requires slavery (public slavery).
Feels a bit like untangling rope, which makes sense
It's fantastic that Cloudflare is offering this. You might want to reconsider calling it CNI, or at least clarify that CNI is just an umbrella term for PNI and/or public peering. I'm the person that handles the PNI/IX stuff and after reading the article but before reading your comment I wasn't 100% sure if CNI was something Cloudflare specific (which we wouldn't immediately adopt) or PNI/public peering at an IX (which we would).

From a comment below, it shows that rougly 42% of UCB is compromised of asian students. I'm sure they are doing fine at UCB anyway.
Go with Golang if you want simplicity. Go with Rust if you want a complex but still neat programming language. Rust is much better than C++ in my humble opinion. I use these programming language as a hobby and I don't think I will ever use c++ on a new project again.
I’m so curious how this even works? Do all ISPs in the UK have an adult content filter on by default?

No idea then. They have been moving things around and in likelihood may have merged the activity endpoint into another endpoint. You may have to watch DNS activity as you launch applications. I've helped a handful of gamers debug this one but I do not have a windows 10 machine to test with. I'm sure engineers at MS are watching this thread and will adapt again. Or maybe someone at MS can use a throw-away account here to say what changes they have made recently.
Am I the only one who thinks it's weird Dyson rips off the title from Samuel Butler's seminal masterpiece? It strikes me as extremely disingenuous; certainly unbecoming his intellectual aspirations.
I've never been that impressed with Go - it seems to be missing a lot of modern features. To me, Zig looks nice from a simplicity standpoint and it fits in the systems programming space.

It looks like CDW, at least, sells by the individual license, to judge from the search results at that link. Top one is "Windows 10 Enterprise LTSC 2019 - upgrade license - 1 license".
Is anyone else here trying to reduce their use of technology outside of the workplace? My hobbies are music, painting, and woodworking, and it's all I can muster to focus on a screen from 9-5. I do comment here on HN and I peruse other websites, but I don't actively engage with any social media except HN.

I just find myself questioning the merits of attention spent on these social media platforms, given the information quality and density is so much lower than HN.

Maybe this is where TikTok has succeeded: short, snappy, quickly accessed videos; much more informational content than textual or image-based FB or Reddit, not to mention more skillfully executed, right? It's like a short-form, Twitter-ified entertainment version of YT.
https://news.ycombinator.com/item?id=24045615 is the most recent example and the only one I remember off the top of my head.
Yeah, I’m totally fine with 8GB standard since aftermarket memory is so much cheaper than what Apple offers and it’s really easy to install.
"mad engineers"? /s
Given the US government’s involvement, and that they’re only buying users in the five eyes countries (except the UK), I imagine they’re buying the surveillance feed.

It’s surprising the UK isn’t part of the deal. I wonder if it’s another sign of the US’s foreign influence waning under Trump.
Very good job, the bonus area made up for the fact that there are only 20 levels :) Opening up the dev console sent the robots for a little jump lol
I think this is totally true. Unfortunately there’ll probably be a set of companies that are destroyed because they are pushed to grow at all costs even though there in a small vertical.
Where in Europe we do it? Most of the countries agree the evidence is rather weak, I wouldn't do such broad generalizations about Europe. No masks in Finland where in at, neither in Estonia or Latvia that I visited.
One thing I noticed quickly is it allows me to see the words as words instead of a string of text.
Without the font i have to focus on each word.

I'll have to try this out.
No doubt these innovations are impressive and will change software developers role. But I think the way to think about this is more like how ML replaced expert systems or ruby on rails helps you write less code using meta programming and code gen. It’s one thing to generate code it’s another thing to maintain it, test it, make tradeoffs, find product market fit, etc. which is the bulk of the job. But we do see innovations in each of those pieces so maybe it will come around sooner than we think and we’ll all be no-code + zapier developers.
> The 27-inch iMac now comes standard with SSDs across the line

Well. Wow.

> Apple today also announced that its 21.5-inch iMac will come standard with SSDs across the line for the first time.

Double wow

I'll be holding out for complete iMac redesign with ARM. I'm hoping something will be announced at their event?
I'm always interested in the differences between Apple's Intel OEM CPUs and the ones Intel lists in their catalog. There is no 10th-gen Core i9 CPU that exactly matches what Apple is selling here. In the iMac Pro they are installing a Xeon-W part that has almost twice as much cache as the standard part (43MB vs 25MB). They're not saying how much cache is in the new 27" iMac.
Building Digital Subscriptions for Hardcore Sports Fans
Very minor correction: you probably mean "complacency" not "complacement". And I do agree to an extent; from where I am standing the American software industry feels a bit bloated/stagnant/wasteful/some word I can't think of that covers all three.
> Because it does not seem to me that they are buying any of the developers, am I right?

If they buy TikTok's operations in the countries or, even just TikTok’s US operations, presumably they'd be acquiring, in either case, the existing US-based business, which (assuming the job listings on their website correspond in the normal way to existing staff) definitely includes developers and other technical staff at the Mountain View, San Francisco, Seattle, and Miami locations, at a minimum.

So, yeah, I think they are getting developers.

Now, do any of those developers work on the core algorithms of interest, or are those just black boxes supplied by ByteDance and shared with Douyin, or if not ByteDance itself some other part of TikTok that wouldn't be acquired? That's another question.
Microsoft isn't a new player. We can look to any number of their past acquisitions. How did they handle Skype? how did they handle Minecraft? Tiktok is just a video sharing app. The code doesn't matter. You keep the old office/database spinning until you have written a replacement. Then users are pushed an "update" that moves their profiles to the new app under the new team.
If we relax the restriction that the columns of the 3x3 transformation matrix must be unit vectors, we also get the ability to apply scaling and shear transformations. In solid mechanics, this is called the F tensor, and is used to describe deformation of materials [1].

There is also an augmented 4x4 form if translation is needed as well:

| Q ... Δx | | vx |
| . Δy | | vy |
| . Δz | dot | vz | = new vector
| 0 0 0 1 | | 1 |

where "Q" is the 3 × 3 transformation matrix (e.g., rotation matrix) that is the subject of the OP, and [vx, vy, vz, 1] is the augmented form of a vector "v" = [vx, vy, vz] that is being transformed.

The augmented form is especially useful for transforming voxel indices in an 3D image array to spatial coordinates, such as for MRI or CT image data [2]. It is helpful if the index coordinate system has its origin at zero (zero-indexed arrays), like a normal coordinate system.

Finally, if we have many [x, y, z, 1] data points that each have an old and a new position, we can compute the overall best-fit transformation from the old to new positions with the least-squares solution to

A x = b

where "A" is the (unknown) augmented matrix representing the transformation, "x" is a 4 × n array storing the points' old augmented-form positions, and "b" is a 4 × n array storing the points' new augmented-form positions. If we allow the points to have arbitrary dimension, without any particular spatial interpretation, we get least squares curve fitting and the foundation of machine learning.

the 12" macbook is my favorite laptop of all time. Mine is the 2016 version and it's starting to feel dated and I'm hoping that they rerelease this on the new silicon first. I'll be smashing the buy button the day it's out.
It's so the "starting at" price is low but they can mark up RAM and Storage upgrades when you actually go to order as if they were the expensive piece. They are making something like 80% margin when you max out the RAM, I assume similar for the "SSD storage" of ambiguous type.

Dell did the same thing with the RAM in a 7740 and 7750 I recently ordered (work and personal), ironically about the same markup.

Great work, funnily exactly what I'm looking for. Thanks a lot!
Crazy that this information is so ... obscured. I had actually contacted Microsoft a year ago trying to do things the up-and-up way, only to get crickets in return. And still, bafflingly, what you found? That's an upgrade license.

It's as if the idea of people putting together their own PCs just never occurs to Microsoft.
I have Win10 Enterprise from a corporate MSDN license. So, I just used gpedit to disable telemetry. What else should I be doing to my install to get rid of all the "leakiness"?
"planarity"

The game is cool, but I think the title is overly general. It contaons a graph visualizer, which doesn't show much in the way of theory; and it's a railroad, not a playground.
There's no 'intel' to support that as far as I'm aware though, just sensible speculation.

Disclosure: I work at Amazon on cloud infrastructure, and I am a technical advisor on FOSS related topics from time to time.

Chris,

I think that the feedback on the CII grant process deserves to be acknowledged and addressed if possible. I wasn't directly part of the day-to-day efforts of CII, but I (as an individual providing one's opinion and advice) supported the original charter of directly funding security related development of critical software libraries that are often unnoticed like libxml2, OpenSSL, etc.

I am disappointed that CII didn't achieve this objective for more software (there were a few grants that were awarded and completed, but over time this seemed to end, from the public updates I read at the time). I think that it is still a good one to have.
If the entrance were, the exit necessarily would be too; so it would work. (The island would be a corner of the maze, you'd just walk in, then left/right (according to hand) and out.
The downvotes are because we actually don’t known the full story.

And of course there are benefits beyond lock-in.

Do you know about the attestation service Apple has introduced?

How would you build such a thing on your own?

If you learn Rust or C++20, the marginal cost of learning the other should be trivial.

After writing a bunch of Rust, I recently had to learn C++. I've been storing C++ in my brain as "Rust + delta of dubious ideas", which, not to start a flame war, has easily been a better compression algorithm for my brain than storing C++ in isolation.

For example:

- C++, const is part of the type. Clearly wrong.

- Rust, mut is property of variable, or & vs &mut. Correct, but lack of & with mut-polymorphism just causes needless suffering.

- Rust construction: good, Rust destruction: bad

- C++ destruction: bad, basically like Rust's. C++ construction: bad, matches C++ destruction.

(I've been saying for years that drop needs to consume, not borrow the thing to be destroyed, but no uptake :(.)
is the telemetry in the source?

in that case, very well. i am happy to be wrong, and retract any claim that VSCode itself is not fully open. thank you.
> but you can buy 32GB of RAM for $150 and install it yourself.

what? Since when did they offer a DIY upgrade path?
Yes but many don’t. Which is why I find it absurd for someone to say they don’t understand why someone would need to use Windows.
But code in any language can be read by any engineer in the world that is proficient in it. I do not speak or read Chinese but when I pull an interesting looking repo from Github that is Chinese I only have to stroke 3 keys to translate all python comments in the file to English. Works great!

You don't need really need another language when you have a common one in place. Even without code comments you should be able to sniff out the crackpots.

Chinese repos are trending on Github everyday. They do really cool things beyond the cutting edge on every side of our business. From frontend react and vue to shiny ML and backend golang.
It's still JavaScript, just implicitly transformed to execute in a different way than it would if you put all the cells you've written in a single file.

If I write a macro in Common Lisp that packages my code in a lambda, establishes a bit of dynamic context around its execution, and perhaps walks the code itself to modify some of its contents, this doesn't make uses of that macro "not Lisp". Yet that's what's happening here, just with less elegant machinery as JS doesn't have proper macros.
The Complete MacLeod Hierarchy (2010)
I wouldn't say entirely that they "didn't survive" considering we're talking about their genes existing within humans today.

Also, long term survival of a species has a lot more to do with luck than you'd think. e.g If cooling temperatures killed off their primary food source and forced them to migrate into human controlled territory where they didn't have experience, they'd be at a disadvantage. But if they lived in a temperature warming era, we may be having the opposite conversation right now. "Guns, Germs, and Steel" is a good summary of this hypothesis.
To add to that: not all up/downvotes are equal.

Sometimes I upvote something that I find very informative and interesting and sometimes because I mildly like it.

I personally only downvote stuff I find very hostile and/or low effort “noise”. It seems that most people do it this way. Except in cultural discussions (includes tech culture).
This is NOT the case, even if the mine was 100% Uranium this would not happen, at least not today. As someone else pointed out, the world did have a natural reactor, Oklo, Gabon 1.5 billion years ago.

When Uranium is refined, they are enriching the U235 vs U238. The ratio is too low today to sustain any natural reactors, but 1.5 billion years ago this wasnt the case.
Yes, they need at least one Apple Silicon machine, which demonstrates that it is competitive for absolute CPU power and of course as a machine for all the developers. They do need not only a testing machine, but should be doing the development itself on an Apple Silicon machine. That is, why I would consider the rumor about a 13 or 14 inch MB Pro with Apple Silicon for highly plausible. The 16 inch would then follow later, with an even beefier CPU.
I think I might the only one who likes and wants bezels on everything that has a display. Extra large bezels. Perhaps the only exception would be phones as they increase the size of the device.

Bezels are important to frame the screen content from functional perspective. Think of it like a frame for the art work. Black bezels occulude the distracting edges and background noise from the screen and you have always have a constant black border. They can be made to look nice as well like some of those Bang & Olufsen TVs[1] and Sony Trinitron Professional monitors [2].

Contrararily, there is no reason to the opposite besides "aesthetics". Can you think of any?

Alas - the momentum behind bezels is so massive, it is impossible to reverse this trend. Same with "borderless" trends in UI/UX.

That's neat, but I'm not sure I learned about graph theory. I liked playing with it but the background was a bit too much for my eyes.
I thought iMacs have an easy way to upgrade the RAM no?
Debt does not matter. This is a great example of nonsense doom.
Sure but Apple is clearly continuing to move in the direction of more security.

The argument that they could be better therefore they are worth nothing, is a clear fallacy.
