I'm going to be honest, it's really hard to read this with a straight face when our current notion of a Metaverse is nothing more than Roblox and some telepresence apps. Hell, those examples don't even fulfill Matthew Ball's Metaverse definition that they referenced earlier on: both of them lack persistence, data interop, and have hard caps on how many people can inhabit their digital space, K8-scaling be damned.

The biggest issue is that none of the companies investing in the Metaverse truly care about the fundamentals. We're rushing in to buy McRib NFTs on blockchains that may-or-may-not exist in 10 years, and McDonalds is happy to turn a quick buck for selling nothing. Similarly, the companies who see this concept as collectible trinkets are entirely missing the point: NFTs are not a social service, they're a digital one. I've seen a lot of people claim that NFTs solve an issue that doesn't exist, and I frankly disagree. The concept of decentralized digital ownership is a huge conversation that stands to upend our current concepts of DRM and online possessions. The issue? There's a ton of money to be made in preventing you from accessing the stuff you want. Rights holders exist almost exclusively to prevent as many people as possible from attaining persistent ownership of their intellectual property. So long as capitalism is the driving force behind the so-called "Metaverse", you can safely assume that the only meta thing about it is how it's hellish reality exacerbates the issues corporations pose to us in the real world.
People who agree with the mainstream, official line, government etc. don't need anti-censorship platforms. Your response to opening such a platform and seeing positions you hate should be "Excellent! It's working as it should!"
I read the page. It's very angry about Wikipedia's finances.

I still don't resent their asking and I still donate.

Wikipedia is a truly worthwhile service and I'm happy they have much more money than they need to scrape by.

You seem to feel that the amount of money they should have is just above what they need to get by. I think that is a bad way to run any operation.
It’s incredible how many people say they’d love to support an ad-free social network, frequently use Wikipedia, and don’t donate to Wikipedia.

This is a problem for so many charities. People passionately agree with the mission, want to donate, can afford to donate… and yet don’t donate. And then complain when the charity is too aggressive in requesting donations.
> You likely have smaller hands

If you add the qualifier "than you", yes, it's not a very risky prediction given the difference between genders in the hand size distribution and the demographics of HN users: https://geogebraintheclassroom.blogspot.com/2015/11/introduc...

Objectively, I usually get glove size 6 to 6.5, but I do consider my hand quite big. I guess I could plug the numbers from http://www.fownesbrothers.com/press/2016/5/10/glove-size-doe... in the distribution above to compute my percentile and see if my perception is accurate.

All this to say, I'll have to be careful to adjust the recommendation by size, as mouse (or trackball) size is an important factor in comfort, and my perception may not be accurate.

> Oh, and one of my more favorite AHK things:

Chording!!! Yes!!! Extending the idea to mouse keys is very inspiring!!

FWIW, like many people I have Caps and Enter using that: Caps and Enter are respectively Esc and Enter when used alone, or Left and Right control when used with other keys.

But wait, it goes further:

- my Shift keys behave as Page Up and Page Down when used alone,

- my Alt keys behave as Home and End when used alone,

- my Control keys behave as Insert and Delete when used alone

In practice, this puts the edit keys very close to my fingers, even on laptop-style keyboards.

I don't always use these alternatives, but I've noticed a tendency for modern keyboard to remove these edit keys, so I want to have a solution ready for when I can't find good keyboards anymore.
I've generally used `PARTITION BY` to achieve the same effect in big query (similar to what was suggested in the article for postgres).

Does the `ARRAY_AGG` approach offer any advantages?
Socure Valued at $4.5B
Yes. The Linux system call calling convention doesn't match the C ones at all. One needs inline assembly in order to interface with the Linux kernel from C.

The ideal solution is to have a system_call keyword built into the compiler that emits the proper instructions for the target platform.

It's worth to note that earlier versions of PostgreSQL didn't include the "AS NOT MATERIALIZED" option when specifying CTE's. In our setup, this had huge hits to performance. If we were on a more recent version of PostgreSQL (I think 11 in this case), or if the query writer just used a sub-query instead of a CTE, we would have been fine.
>>Findings In this cross-sectional analysis of 26 823 adults from the population-based French CONSTANCES cohort during the COVID-19 pandemic, self-reported COVID-19 infection was associated with most persistent physical symptoms, whereas laboratory-confirmed COVID-19 infection was associated only with anosmia. Those associations were independent from self-rated health or depressive symptoms.
> t's somewhat amusing to see someone write a lengthy rant against testing because memorizing information is archaic, when the ability to write, at least at the start, is learned this way.

Writing is a skill. It is NOT memorization. It is not taught or learned that way, even at the beginning, unless you are talking about handwriting.

No one says, "Memorize this phrase, and now write it out again."

Regarding "Match Against Multiple Patterns", the examples are about finding the _suffixes_ of something, email domains in the example.

An attempt to find a suffix like that will not be able to use an index, whereas creating a functional index on the reverse and looking for the reversed suffix as a prefix will be:

# create table users (id int primary key, email text);
CREATE TABLE
# create unique index on users(lower(email));
CREATE INDEX
# set enable_seqscan to false;
SET

# insert into users values (1, 'foo@gmail.com'), (2, 'bar@gmail.com'), (3, 'foo@yahoo.com');
INSERT 0 3
# explain select * from users where email ~* '@(gmail.com|yahoo.com)$';
QUERY PLAN
--------------------------------------------------------------------------
Seq Scan on users (cost=10000000000.00..10000000025.88 rows=1 width=36)
Filter: (email ~* '@(gmail.com|yahoo.com)$'::text)

# create index on users(reverse(lower(email)) collate "C"); -- collate C explicitly to enable prefix lookups
CREATE INDEX

# explain select * from users where reverse(lower(email)) ~ '^(moc.liamg|moc.oohay)';
QUERY PLAN
----------------------------------------------------------------------------------------------------
Bitmap Heap Scan on users (cost=4.21..13.71 rows=1 width=36)
Filter: (reverse(lower(email)) ~ '^(moc.liamg|moc.oohay)'::text)
-> Bitmap Index Scan on users_reverse_idx (cost=0.00..4.21 rows=6 width=0)
Index Cond: ((reverse(lower(email)) >= 'm'::text) AND (reverse(lower(email)) < 'n'::text))

(Another approach could of course be to tokenize the email, but since it's about pattern matching in particular)
On the topic of diploma - I get the sense this is not exactly true for FAANG
This is appeal to fear, a logical fallacy.
pretty much. You lose access to the wallet and don't have your private key backed up, then its gone. Most wallet providers bug you to back up your key seed and even test you to validate that you have.

Just like losing the key to an encrypted file.
I know nothing about this issue: I had to look up https://en.wikipedia.org/wiki/Extremely_high_frequency to learn what mm-wave electromagnetic radiation is.

Other than attenuation caused by rain-drop scattering and atmospheric absorption, I couldn’t find much information about the downsides of using EHF EMR in the context of cell networks. Can you recommend any good summaries of developments in this area and its associated risks (privacy or otherwise)?
What's the legal expenses associated with Wiki? I could see some people wanting to sue for information linked to/about them. OSM probably doesn't have that same type of exposure.
It works the other way too; the implementation is not obligated to pass an interface value to a function. The interface can be monomorphized too, if the compiler saw fit, and it would be a compliant implementation.

At the language level, it's a useless use of generics. Even if generics someday used a monomorphic implementation, the compiler would be able to translate those two things back and forth trivially.
I mean you are just wrong. You memorize what sound (well sounds) the letter "a" makes, which is of course fundamental to being able to write because English uses an alphabet. You might argue that reading isn't writing, but the two are interdependent (or at least writing generally dependent on reading).

Not to mention memorizing how to physically write (i.e. what you're talking about with handwriting)...

I assume you think I mean composition or something, which is of course extremely obviously not what I meant... But to develop that skill of "writing" that you're talking about requires memorization of the fundamentals... Which applies quite broadly to other disciplines...
It's cheaper because users are the ones who pay for it. The less conscientious people are at each layer of the stack the bigger the snowball gets.

It isn’t. I have the same overhead running my server as I do a VM. What I don’t get is a $3000 bill for $100 worth of server.

You can generally buy whatever you are renting from AWS for 1 to 3 months of an AWS bill.

The only thing I don’t get from colo is a bunch of other customers thrashing the cache on my CPUs

Databases are not web servers there’s no possible way to not run a database on smaller / fewer instances when running at non-peak times. Instant scaling is the only possible advantage AWS could bring. However with the prices they charge it’s simpler and cheaper to just buy/rent your own hardware. Especially if you have to pay egress fees. (bandwidth is really the biggest ripoff)

I've donated thousands to Wikipedia over the years, but I've noticed an increasing amount of bias in the website that made me hit the pause button. At first I saw it in a couple random examples, where I just thought "that's weird" and dismissed it as a random issue. But then I started to look for bias and noticed it much more frequently. And I don't mean just on the left-right American political spectrum, but also in other more complex ways, for example favoring Western scholarship over other scholarship. When I look at the Talk pages, I see regular bad faith application of policies that were written with better intentions.

I'm not the only one to note this issue in recent years. Larry Sanger, co-founder of Wikipedia, wrote a blog post titled "Wikipedia Is Badly Biased" last year (https://larrysanger.org/2020/05/wikipedia-is-badly-biased/). Although Wikipedia is decentralized, it is an institution. And I feel like we need more than one.

It is also regionally accredited, which is important if you are hoping to go onto grad school or transfer credits to a different university later.

I am about 75% through the program and for someone who has been in the field for a while, it is really good. A lot of classes have just been taking a quick test to prove competency, but the discrete math and computer architecture classes were really interesting and useful.

That said, I'd be slightly hesitant to fully recommend it to someone who had zero prior programming experience. The fact that there are no assignments and only a handful of courses that require projects means you can graduate without having written a ton of code, and the code you do write is somewhat disjointed - a few Python courses, 2 Java courses (with a heavy emphasis on JavaFX), and a random C++ course that seemed pretty out of place. I don't that is the worst thing in the world, but if someone comes in cold and just checks all the boxes to get through the program as quickly as possible, they may find themselves ill-prepared for interviews and their first job.
You don't have to, the chuds will do it naturally.

I think there is a need for this. I use it daily and still find myself relegated back to pretty much the features that were available when I first picked it up - would love somewhat of a refresher book that is updated for 2021/2022.

Customer engagement manager
I either found a way to unsubscribe from these, or I found a way to filter them. I now make a monthly donation, and I see the receipts from those transactions, and that's it. Just the way I like it.

Contrast with the Red Cross, whose annoyance-to-value ratio is far worse, IMHO, to the point that I refuse to donate. Yes they're providing literal life blood to people who may die without it, but have you SEEN their firehose of email?

I don't understand why this continues. It must work better than the alternatives, which is awful.

Privacy Preserving Machine Learning: Maintaining Confidentiality
That is true, but that has never been a bottleneck for me. We have a table with multiple hundreds of millions of rows, 20ish UUIDs indexes (yes it did get out of hand) and insert time isn't an issue.

Ofc, your app performance requirements might vary, and it is objectively true that UUIDs aren't ideal for btree indexes.
The loss of Car Talk and the changes to A Prairie Home Companion all but eliminated my weekend listening. Wait, Wait... is OK but I usually don't tune in without the other stuff to draw me. The other new comedy show (with Coulton and Eisenberg[?], I forget the name of it) isn't very good. Maybe they'll find their footing, but it's been years at this point, and it's still not good. On the Media is really good, but plays at a time when I'm almost never driving, so I rarely catch it.

Their weekday news shows are too corporate-friendly and consist mostly of the same horse-race and monday-morning-quarterbacking campaign strategy garbage that everything else does, when the US is in national political campaign mode, which is like 60+% of the time now. The best US and international coverage on the whole damn station is when they just re-broadcast the BBC.

[EDIT] Oh and there's the huge amount of time they spend either advertising or promoting other NPR shows or podcasts. God damn, it's so much. It's at least as much time as "commercial" radio devotes to that kind of thing. Donate? You fucking play corporate ads! All the time!
Yeah, I've heard about a classist element in Europe that might make the path I took unlikely. I dropped out of college, toiled in the service industry for 10 years, got sick of it, went to code school, got a tech job and 6 years later earn $130k. Still no degree. Is it true you can't do that there or is that just a stereotype?
The Go Programming Language is still pretty much up to date. Most of the recent updates have involved improvements to tooling (Go modules), improvements to the standard library, and internal optimizations.

The big changes I'd point out are `context.Context` and `go mod`. I might be forgetting some things, but those are most notable to me.
But as a developer, why would I devote my resources to support these Gucci clothes when I get 0% of the cut of the sales of these clothes?

Developers like paid cosmetics because they get to sell the cosmetics. If its Gucci selling the cosmetics, and the people are just clicking a "Validate" button and somehow proving their ownership of the NFT, what incentive is there for the developer to add those clothes?
I would iterate off the end of a C array.

I would have a function call itself recursively a million times deep.

I would use a pointer that was set to a random value.

I would return the address of an automatic (i.e. stack) variable from a function and use it later.

I would allocate resources in a loop and never deallocate them.
Conan O'Brien went to Harvard, so we've already degraded the value of having a degree in general.

I think there's a big gender and culture gap in the VR/AR debate.

People who place significant value in their physical appearance (eg most young women) are not in a rush to replace their bodies with an avatar. And we know that men go where the young women are....

Now, can Facebook or Microsoft succeed by serving the fantasies of nerds like us who read sci-fi as a kid? Of course. But Apple is still in pole position given that they are targeting the mass consumer market, not a niche.

No diploma here - still have recruiters from at least 3 of the 5 messaging me.

When I visit a restaurant, I sometimes ask the waiter whether he knows if certain dish contains dairy. There are usually three answers:

Bad waiters would just have no clue and won't know what to do.
Mediocre waiters would offer to go to the kitchen and ask about it
Great waiters will tell me yes or no, will offer me to cook it with X instead of Y, or give me one of the other options in the menu (they already know by heart) that do not contain dairy
That's a nice statement sounding like straight from Amazon sales reps, and it can actually work for some companies, maybe. But for our bank (top 10 globally), the only way to get even equal financially to our own farms is to have aggressive downtime every night that negatively affect productivity of our global teams. Pricing is really not that great if you deal in scale.

You wanna push 1 evening a bit late to deliver something valuable for the project? Sorry, no can do.

I don't even factor in horribly expensive migration projects that brought actually 0 added business value for the type of apps we use. We still have to keep our Network, Windows and Unix admins, various App support personnel etc., there is plenty of work for them with AWS. Not 1 single IT guy was made redundant.

No cost savings, in contrary.
> Shouldn't there be a sort in there before the uniq?

Probably. uniq only removes duplicate lines when they're adjacent to each other. I doubt the git grep command output has all the matches adjacent.

I've read it's more efficient to use 'sort -u' instead of 'sort | uniq'. These days I only use the latter if I need uniq's -c to show the count of matches for each unique line.

You assume 'repairing under warranty' isn't done with simply replacing the entire device. You are aware that this is standard practise anyway right? Right now you are most likely to get an identical refurbished version of your phone while your own hardware is queued for repair, mostly off-site.

As for the hypothetical cases: that is indeed what I wrote they were as well as why I was writing them. They are real world cases that apply to any consumer goods manufacturing pipeline. (albeit anecdotal as I'm not in the mood to dox myself) You do not know the details of Apple's pipeline and are speculating about it, as am I. Your speculation, however, is a plain anthropomorphisation of a for-profit company that really has no merit. There is no money in 'being bad to customers at scale'.

Every reply of yours has either been some irrelevant detail that doesn't match with what is happening in the real world, or it's some bigger picture that doesn't relate back to any multinational global consumer goods lifecycle.

Besides the fact that being able to repair consumer goods is a good thing, we're not getting anywhere.
To be even more cynical, they only tolerate scalpers if they personally stand to profit from the scalping.
