I recall Paul Halmos (https://en.wikipedia.org/wiki/Paul_Halmos) once advocated for naming things in mathematics descriptively rather than honorifically. I recall his argument was that it aids in recall and understanding to name descriptively, and that there are better ways to honor discoverers.

I found this statement in "How to Write Mathematics" (https://bookstore.ams.org/hwm):

"... surely I cannot stop without a discourse on the proper naming of concepts (why 'commutator' is good and 'set of the first category' is bad) and the proper way to baptize theorems (why 'the closed graph theorem' is good and 'the Cauchy-Buniakowksy-Schwarz theorem' is bad)."

I thought he'd said more in "I Want to be a Mathematician" (https://www.springer.com/gp/book/9780387960784), but I just looked through the book and couldn't find anything. (Halmos was a particularist, and thought very highly of examples, and "I Want to be a Mathematician" has examples/opinions of how to do nearly everything in the profession, from teaching to writing to being a department chair to giving talks to doing research ... He was very opinionated, but also specific and absolutely clear, so at least if you disagree with him you know what you're disagreeing about.)
Actually it seems to be worse:

- Donations goes to the foundation

- Profits from the corporation (after engineers are paid for) goes to the foundation

Net money never goes from the foundation to the browser it seems.

(Please anyone correct me if I'm wrong. Also, I'm not necessarily saying their projects are bad, only that when they go at the expense of Firefox something is seriously wrong.)
I'm not sure I need much effort to pinpoint the motivation of people who are enjoying free drinks and free fancy dinners, both of which would otherwise be outside of their financial means.

But I do agree with you, the chance of potentially marring a billionaire is probably also alluring.

It's just that I wouldn't want to be the guy that is married only for his wallet, because that sounds like a surefire way for being treated like a tool.
You know, I'm sure these articles get written to spark a little jealousy, a little outrage.

But you don't have to participate at all, or even get affected except as a casual outside observer of the ridiculousness. People will be willing participants in a whole lot of stuff, not all of it good for them. The club owner, the "pimp" in this case, the mark, the girls. They can all walk away.

But they don't. And that's their choice.
> Gecko is stagnate and in maintenance mode, all of the improvements to Gecko come from Servo, thus no servo no improvements

I think you misunderstand. Servo was a way to test and prototype things, and some of those have been merged into current gecko/firefox.

Gecko is not in "maintenance mode", it is in active development.

I'd love if Servo development continued, but the picture you paint is just plain wrong.

Classic innovator's dilemma. The benefit of spotting fake reviews is too small for a company of Amazon's scale, so the company doesn't spend (meaningful) resources in pursuit of that goal. Amazon has no way of knowing which, among the infinite number of small projects that may end up becoming a commercial necessity, are fated to grow to that size. This allows smaller competition (here, Fakespot) to do move quickly, execute, and seize that benefit which, for a company of Fakespot's size, is highly meaningful. The momentum that a company like Fakespot builds while building out Fakespot's service allows the quality of Fakespot's service to outstrip and embarrass Amazon's parallel attempts.

> I think this argument is getting a bit old, as Amazon's growing reputation for fake reviews (and fake products) is turning off even mainstream shoppers and giving a huge boost to big & small competitors. Amazon now has a very big financial incentive to move beyond whack-a-mole and truly tackle these problems

Citation (unfortunately, still) needed. "Very big" means something quite different to Amazon at Amazon's scale.
Why anvils have the shape they do
From experience: The only thing I agree with on the "do not use the basic colors", is that some C-level stakeholder 5 forwarded emails down the road (and never present on the status calls), will not bother to read the damn thing fully, and will see the RED on statistic-X and will think that the X-thing is doomed and we need to slash this project/product/function. Yes, I agree, it's not a color thing, it's a RTFpresentation-thing. But the use of non-standard colors (red-amber/yellow-green) will avoid these mishaps.
>"I don’t know why this was voted down"

I suspect it was not because of C++ but me mentioning a monstrosity of some modern back end stacks. I think people get attached to the way of doing things and it becomes akin to religion.

Are you suggesting that that one should be OK with this kind of world, or simply observing that a world like this ought to make one bitter?

To be clear, I'm not condemning this system. Just explaining that this is what a K-shaped recovery might mean. That those with very little are left out when most of the "recovery" comes from the Fed propping up asset prices while everything that isn't sufficiently similar to a security crumbles.
I knew what his point was. I meant to say "hardware" instead of "software".
100x the size is neither beneficial nor harmful when controlling a pandemic. As demonstrated by the US’s successful reduction in spread before opening things up again.

0.9 new cases per existing case and it goes away. 1.1 new cases per existing case and it grows uncontrollably. There isn’t a true middle ground.
Ask HN: Visualizing a Sphere
Hi HN,

This is going to be a strange question; but if any audience is going to appreciate it I think HN will :)

I started meditating in January with the goal of reaching an hour of consecutive meditation by the end of the year. I’m on a 218 day streak and I’m already up to 62 minutes and now intend to get to 90 minutes by the end of the year.

Another hobby is reading, where I have been able to use the right hemisphere of my brain to visualize concepts rather than subvocalizing the words, bringing my reading speed to 500-600 words per minute with a solid understanding (non-fiction).

My question is: how can I understand and visualize a sphere in my mind’s eye from an atomic and mathematical perspective? E.g. what books on geometry, physics, equations, or techniques would one recommend?

Why a sphere? As I’m sure many here know it is the most powerful of all shapes. Planets are spherical due to the pressure of their own gravity, this shape has the least amount of surface and thus conserves energy.

It’s a Sunday so hopefully you’ll entertain my strange question :)
Ask HN: Why HN lacks a reply alert feature?
I don't know if meta posts are allowed or not. I am quite new to the community. Trying to learn from mistakes here.

Why don't we have a "reply" feature, that alerts on every reply to a comment on any thread?

Its very difficult to check manually by navigating through own comments, especially if there are comments on more than 2 threads in a day.

I don't want to compare, but lobste.rs have implemented such a feauture and I find it very useful.
I used to work at a largely ad-supported community site.

Users requested an ad-free paid membership, but when we ran the numbers, we found that those people willing to pay made the site much more in advertising than a reasonable subscription could.

However a while after I left they launched the service, so maybe they’ve managed to make it worthwhile.

I'm probably a vim power user, but I stopped adding to my knowledge years ago because nothing seemed to be adding to my productivity. It sounds like Carmack just hit that point earlier.

I feel this way about version control systems. More trouble than they are worth to me, even when working in the same tree with many others. If I make a branch, it's only because that's the only way to submit a PR. Merge conflict? I'll look at my diff and apply it manually to the other side. Merkle trees are great, but the only useful history to me is a straight line!
I've never used termdebug. Here is some info:

If that is accurate (it looks like it is), why is termdebug faster than keeping open a second window and using gdb there?
>Whites will become the minority in U.S and the UK in the coming decades. It's not that different in West Europe, Canada, Australia, etc. Overall it's a good trend for immigrants.

1. The US may become a white-minority country. Europe, not really. Whites are still the majority, and are going to remain so in the distant future. The "Great Replacement" isn't real.

2. Most immigrants to EU countries are from other countries within the EU and white themselves.

3. Many people from outside the EU, even though they're not considered "white" by Westerners, look white from the outside (think of e.g. Arabs) and the differences are purely cultural. Within a few generations you wouldn't be able to tell the difference between them and "white" people.

4. One's ability to integrate and be welcomed depends far more on cultural differences than "looking" different. This is why people from former colonies immigrate to the country that colonized them - lasting vestigial ties and a common language help far more than sticking to people who share one's skin color.

Oddly enough, the more tangible benefits to society a job provides, the less it is paid for. It's almost like a "your job is not bullshit" salary deduction.

From bakery to supermarket to food delivery, pretty much all of the people I interact with daily are paid badly.
I know enough vim to get around, edit, and search/replace. I put in the original effort so I could edit files on any unix server I ended up on. I also like the modal editing concept.

But, even though I bring vim keybindings to all my local editors, my day to day is still a mix of vim + mouse navigation (and cmd+t obviously). I have never felt hindered by not being all vim.

I do touch type though, and have known programmers who hunt and peck with their index fingers. Not being able to type nowadays always seemed odd to me since, I just assumed people would learn to type better by being at the computer all day.

For the totalitarian claim to rewrite history all territories are ultimately problematic.

> We don't know a perfected totalitarian power structure, because it would require the control of the whole planet.

- Hannah Arendt

I would add that several totalitarian singularities, that each are closed off from one another or perceive each other through a completely controlled ideological filter, might also constitute such total control.
I have this view that the previous era of social structure was crafted through long trickles of actual know-how. This made the authority feels a bit stiff, but with the new open land of interwebs we're seeing how a "fluid" variant is mostly good to drown in.

ps: side note, I tried to leverage access to direct science (pubmed and similar) and I was quite surprised that the struggle you describe for mundane topics (no offense to your family) is similar in deep research. A gazillions of publications all talking about similar things but with various conclusions and a lot of maybes. I kinda saw that human society is that thin autofocus line between high education doubts and high ignorance. We live in the 'field tested' middle ground which is not truer, just more agreed upon.
Fair enough - the system isn’t perfect; however there is no perfect system this side of heaven. I’m open to many kinds of reforms of the criminal justice system. The important thing to realize is that there are only trade-offs, no perfect answers.

Still, defendants still have rights and get due process in court. It is not reasonable to jettison all of that because sometimes we don’t like the outcomes.
I find Sublimes "power" features really useful for the tangential stuff. Getting a good look at a JSON object, preparing some mock data, preparing one-off data. Basically everything that falls before the threshold of being worth automating or writing a script for. With multi-line edit and a couple of plugins you can do some "excel" like stuff without the overhead and with the simplicity that plain text brings.
Yes, but I don’t think you’d want that, as the navigation after that wouldn’t be the same (you don’t press Down again to move between windows and then let go of Ctrl to select; rather, you let go of Ctrl, move between windows with the arrow keys, then press Enter to select.) Better to keep the two muscle-memories separate.
And not letting someone who wants to know if you are going to the meeting later upset the entire house of cards.

You are still talking about mapping the simulation to a representation that will make sense to you.

The episode that I found fascinating to think about is when a simulated character reflects on his existence: “And if the computations behind all this had been performed over millennia, by people flicking
abacus beads, would he have felt exactly the same? It was outrageous to admit it-but the answer had to be yes.”

It looks like the physical medium and the representation do not matter to the simulation, as long as computation occurs. Then the question is, what is computation. If you believe that all digits of Pi exist, then every possible computation should also exist.

We don’t usually believe that. It seems that information in our universe cannot exist without some physical medium.

The out of order computation was added to the story to make it more dramatic, the author states.
How do you get started with learning GPU programming? I mean that in a pedagogical way, like what is the best educational way forward. Build stupid stuff in shader toys?
There's these things called books, think of them like a paper backup of a webpage. So anyways these books can have all sorts of information in them.

I have heard about, but not seen, books about computers and programming. Apparently some were entire reference manuals for various programming languages! Can you imagine? These books don't even need to be charged to use them!

I know it sounds crazy but they're real things. I once met an old guy, you know over 25, and he told me that before YouTube and StackExchange that people learned to program entirely by using books and typing at their computers.
There used to be one actually at one point in time--I think? It was long enough that I can't remember its name anymore, so I'll have to let others help out with this thread.

Personally, I'm glad it doesn't exist. I don't expect HN to be like every other forum out there.
I'm curious, then: why not use the modern variants? What is it about the TI BASIC experience that you'd rather have?

Reason I'm asking is I'm working actively on a TBA project around retro-ish BASIC hardware/software as a learning / confidence-building tool. I'm genuinely curious.

Related: have you seen the PICO-8 system? It's Lua, but it's specifically designed for games, has some nice constraints that encourage a certain retro look & feel, and is pretty approachable.
The saddest thing I see in these comments are always people hating on some minor thing like Pocket or something and who has decided to go with Chrome instead :-/

I mean I get the frustration but this is "cutting off the nose to spite the face"-level logic IMO.

BTW: There was always something. Back in the day I think people hated on awesombar and used that as an excuse to stay with IE6 ;-)
If you go to Belarus, you would rather hear that IT prospered because Lukashenka could not figure out how to extract money from it easily.

There were a few attempts at hostile takeovers of IT companies by state actors, but the state could seize only used equipment. Staff moved on, clients fled.

So, at some point, the state just decided to let IT free at the effective tax rate of 9% (against 52% for the rest of the country).
So, I agree, somewhat.

I am a long-time Emacs user. Occasionally, editing/macros/etc can save a LOT of time, and makes it much easier to make some changes which I might not decide to do.

What I find more important however is the effective window/buffer management. Being able to manage my screen real-estate is killer; being able to do everything within one "world" is really valuable. One of the things I find most valuable is that I run my shell within Emacs. This lets me keep my flow going instead of switching context and perhaps getting distracted. I can watch the output of tests etc in one corner of my screen and edit files etc in the other ones. And because its quick to switch buffers, I can more easily reference various files for what I am doing.

Basically, the literal time it takes to type is not the big benefit, but that it allows me to reduce my cognitive overhead of doing everyday, boring things like resizing windows, looking up symbols/finding definitions etc. This makes it easier to focus on my task at hand and not get distracted by all of the mundane tasks I would need to do otherwise.
While it does default to binaries, it accepts a build-from-source option

I haven't been involved with macports recently enough to compare, but one advantage of Homebrew's popularity is the depth of package specifications and how quickly they're updated
Yep, this is a totally dumb one. It is actually labeled "24 amps max, 20 amps max per outlet, 20 amps max per bank", hence the NEMA L5-30P so it can try to make sure that guarantee means something: https://download.schneider-electric.com/files?p_enDocType=CA...

The "banks" are just one half each of the total outlets. The PDU's lil segment display flashes between the integer-rounded Bank 1 load, Bank 2 load, and Banks 1+2 load, and the same data is available with more precision through the serial or Ethernet ports. I have my beefy workstation and NAS on the bottom bank and all my network gear on the upper bank, so right now my PDU is flashing between "3", "0", and "4" amps respectively (rounded): https://i.imgur.com/o50UJoO.jpg

Honestly I'd be more worried about fire hazard if I used an equivalent “legit” setup with three power strips and three Kill-A-Watts.

a lot of rural or provincial towns in Europe are in terminal decline for many reasons, but chief among them demographics.

My family comes from a very rural German village. There is no economy, there isn't even a physician any more since the last one retired, everyone commutes over an hour to work in the next big city etc, and this is systemic.

Some people may not see it that way because it's always painful to uproot ways of life but I think the case for the prosperity of those regions is virtually impossible to make, and it's getting worse steadily.
Yes, the irony. But it's coming from the same place as technical people being horrified by the wanton adoption of Internet of Trash devices, and preferring simple appliances. We know there's a proper way (privacy preserving digital payments), and until it's there, we'll reject ersatz alternatives.
No one asked for their phones, tablets, and laptops to be even thinner, especially at the expense of serviceability. Everyone knows that batteries stop holding charge after a while. General public knows it and engineers know it. But nope, let's build a device that's ridiculously thin and not designed to come apart at all because screws are so not pretty, right?

Water resistance is a feature that most people don't need (me included). It's nice to have, sure, but how many people choose one device over another because of it?

As for damage resistance, are you sure about that? Modern gadgets are ridiculously fragile for no good reason.
> The achilles heal for sellers is that their listings ultimately need to show up When searching for unique information specific to a particular product. They’ll often try to hide that in an unrelated field or in the description. Usually a seller uses the same “trick” for all their listings.

By unique information, do you mean descriptive adjectives or product features? If so, these terms more often than not show up right in the title:

Government validated identification online sounds like pure hell to me and the antithesis of an open and free internet, which is already under assault in many different ways.

I don’t think that Amazon needs government backed identification to be able to weed out fake reviews.

They could start by allowing only reviews from actual purchasers of the product. (I assumed this was already a restriction they had in place, but I just checked now and, of course, they appear to allow reviews from any registered user).

They could also only allow reviews from accounts over a certain age or with a minimum number of purchases or who have completed additional identity validation, either themselves or through some other third party.

Point is, it’s not an insurmountable problem for them. It’s just either not a priority or something they actively and intentionally do not wish to stop.
