Presumably what hyko means is: VR is much more accessible than it was 15 years ago; but VR isn't exactly common, even among the sort of dedicated PC gamers who take part in the Steam hardware survey, and it's doubtful Facebook's average user has a beefier PC than Steam's average user.

So it's difficult to imagine a future where VR becomes a bigger part of Facebook's business than Facebook/IG/Whatsapp. I don't imagine I'm going to be visiting grandpa in the metaverse to look at family photos any time soon.

NHK (the Japanese BBC) is reasonable.They focus on east-asian news, but they're a breath of fresh air every once and a while.
I worked in one... engineers didn't work quite that much but about 60 hrs a week. Saturday a full day is standard all year around. The peculiar thing was that right next to our cubicles there was a level 1 phone tech support team. Those guys worked exactly 40 hour weeks. Or team of test engineers were paid $600/month. The tech support guys only $400. I would often ask the engineers if they were cool with the fact that they made the same pay as a phone guy but had to work much harder. At first they were all puzzled, then I'd point out their hourly wage. They all would respond that it didn't matter, it was about social status. Even some of the ladies working in designer bag stores made better pay than them, but didn't have the statis in their view. It kind of blew myind, status means nothing to me, but I am considered eccentric. Anyway, thankfully my base pay was higher than both groups due to nationality.
That's why it's a market. If they do that, and you seem the pushing policies that you don't think will work, you and everyone else who likes money can bet against them. Bribery would be prohibitively expensive relative to the value gleaned, if the market were liquid.
Sorting chunks by similarity: commonly used tools don't do that. Most archive tools only sort by file type.

I wrote a tool that chunks the data (into variable-sized blocks, to re-sync if there are multiple files that have different length prefixes, but that's another story), and then sorts the chunks by LSH (locality sensitive hash). LSH is used by search engines to detect similar text. It can compress directories that contain multiple version of e.g. source code very well (e.g. trunk, branches). https://github.com/h2database/h2database/blob/master/h2/src/...

I discussed this approach with a researcher in this area in January 2020. AFAIK there is active research in this area, specially to compress DNA sequences. But he also wasn't aware of papers or research in this area for general-purpose data compression.

So, I think this area is largely uncharted. I would be interested (as a hobby side project) to help, if somebody is interested.

Summary:

* Regular compression algorithms use a certain "window size": this can be 32 KB, or 2 GB, or so. But sorting chunks can be faster faster and can improve the compression rate.

* Regular compression tools can sort by file name and file type.

* Data de-duplication tools (e.g. enterprise backup tools) chunk the data in a smart way, but then only support exact duplicates (not near duplicates).

* Locality sensitive hashing: it is not used in common compression tools so far AFAIK.
This is fundamentally a data virtualisation approach - even though it is achieved by streaming replicas and fdws instead of tradictional data replication tools.

It is probably more complex than replicating a single database to a Snowflake, but one huge benefit of the described solution is that it's real-time - and getting realtime replication to data warehouse is a very different challenge.

It allows you to create both batch and realtime data products just by creating views or materialized views, which is pretty simple and neat. You also get real-time ad-hoc querying, which is very valuable.

The issue with this approach is it keeps the data in row-based format so from certain size it isn't going to be practical. For the "daily report" use case, it's probably fine for a while, but if the source system grow to terabyte size, you will be spending a lot of time waiting on Postgres to do it's thing.

So as the data grows, you might lose first the real-time ad-hoc querying (if you ever had it), then the real-time reporting and then the daily reporting.

But maybe the data will never grow that much and everything is going to be fine for a long time? Maybe this gets you where you need to be for a few years and who knows how the data platforms will look like in a few years.
its strange that a company with "git" in their name would be worried about offending people
Yeah, for the most part, the point of the OSHA rules is not because employers are forcing the workers to do risky things, but so that employers put processes in place to monitor and prevent their workers from going off and doing risky things.

Most people are self-motivated, but they may not be good judges of risk, and a small group of employees go off and do something reckless, get hurt, and now everyone needs to follow safety protocols that reduce risky behavior even if these impose a cost for the 90% that would use common sense and avoid danger.

The counterargument is we know something about human nature, so procedures that are dangerous to reckless people is a problem when you are a large business and a given percent of your workforce is going to be reckless.
Some of us avoid devices that depend on (forever changing) hacks for normal usage.
Solar+wind+storage could though.

Plus, what never gets factored into this, is a sane discussion about industrial uses. Switching off industrial users in extreme events (light winds/cloudy for multiple weeks) has a cost, but that could also be factored in to the costs of relative power strategies.
We already have these kind of contracts — perhaps we should be more aggressive in pursuing that?
I do a similar thing with constant keys. Check the result with a simple memcmp/strcmp of the key for false positives. But only usable for constant perfect hashes.

64 bit is not good enough for that claim. 128 would be good, 256 perfect for production use. Regardless of the hash function quality. wyhash is a very good hash, the best and fastest portable one.

In fact, 4 10s aren't much harder than 4 8s - for me travel time was dominant as I had to physically go run a lab. So I actually kept my salary while getting permanent three-day weekends. And I justified it by being able to get setup and cleaned up outside of normal work hours which was true and glorious.
Now if only Cook could reinvent the autocorrect feature.
> The data regarding the trend is pretty clear.

Apparently it's not, see parent comment. Doubling-down and ignoring the criticism is downright dishonest.
> Yea, letting physics run it's course will take 100,000 years too with a plutonium half-life of 24,000 years. A country like Germany doesn't have vast desert lands to store dangerous materials reliably for that long. It's also not willing to just dump it in third world countries or international waters.

Just burn the waste and distribute it from smokestacks. That's how coal handles its radioactive waste, and that seems to be accepted.

I agree however, that it's hard to argue for nuclear when it takes so long to get plants built that the developers die of boredom before grounds is broken.
Facebook has sold multiple millions of Quests, and are on track to sell a lot more. Anecdotally, lots of non-technical people in my life have jumped on it. Even my older, non-technical parents have enjoyed repeated games of VR mini-golf.

Nice talk!

16:00 "fission drive" sounds exciting, so in principle I can have data on my disk, also distributed via IPFS and available to local-first apps. This is something I've had in mind as a "data mirror" [0], it would be cool to interoperate with data from various silos and build apps/alternative clients on top of it. I've got a bunch of data extractors/normalisers already [1], would be interesting to try and connect it!

By the way, for demonstrating offline mode, both Chrome/FF devtools have network throttling (which is also useful for triggering/testing race conditions). In Chrome offline mode is also in devtools, in firefox offline mode is in "menu - more - work offline" (which is a bit less convenient, but still)

Who is actually doing this work? I have had an idea for a kind of 'public meta-analysis' site, where we could give simple headline figures for important questions like this based on consensus estimates. A bit like the Cochrane or Mental Elf, but for everything and producing a dataset of actual numbers to be used in arguments like this. It's so frustrating in comment threads like this that nobody actually has reasonable numbers for the fundamental assumptions of the arguments on either side.

Lo más destacado de la semana (08/02/2021–14/02/2021)
Agreed. A plausible explanation for why the largest companies are tech companies is low marginal cost of replication combined with widespread appeal combined with network effects and IP moat which confers monopoly margins.

Other businesses are constrained in a way tech companies will never be (geographical, meat space constraints) and are in legacy industries where decades of competition has eaten away margins.

The explanation that the tech CEOs are better (although I'd agree with that statement in general) isn't the best one.

Real estate rarely goes down, outside of a total bubble deflation. People just hold onto it longer, unable to profitably sell, further trapping others in a cycle of rent.

The current bubble will drain money from producers to the value-empty mortgage sector for decades.
We're not used to having frontiers any more.

But a couple hundred years ago it was normal for families to yeet themselves off to another continent to start new lives.

This trip could take months, in some cases years (some of the stories from early Australian colonisation are crazy).

On arrival, the incomers were often left to their own devices in a hostile land.

If we manage to get the transport costs to Mars down to the kind of level where selling your parent's house will pay for it, we can expect the same response - people will want to go there and start new lives.
Too bad. Humanity will probably suffer.

The real long tail risks from nuclear are the long term ones, which aren't factored in because we don't know what nuclear storage sites will be like in 100 or 1000 years. That's what many rational people object to about nuclear power — it involves a massive discounting of future risk, and we know people are really bad at over-discounting future risk in general.
> Unless it's actually not that simple?

Recognising that given sufficient domain knowledge you could minimise and optimise dependencies and actually having that domain knowledge for this specific field are not the same thing. For the former, you just need to be a professional. For the latter, you need to be in luck for this specific subject.

You don't fix that by being snarky. Ironic, because in the last paragraph you do ask for constructive criticism! The least you could do is materially reciprocate in doing so.

From a practical POV: logging in with Samsung account would be OK. Logging in with Google account wouldn't, for the same reason Facebook isn't.

It's because ToS violations tend to be executed against the whole cloud account. Do something stupid in a Samsung VR game? The hypothetical Samsung headset is now a paperweight, but at least that's all that happened. Nobody uses their Samsung account for anything anyway.

Do the same on Quest, and you lose your Facebook account. Or, post something on Facebook that their automoderation doesn't like, and you lose your Quest.

Same stuff happens with Google all the time. My favorite example is how a lot of people lost their whole digital lives because they commented with emojis on a YouTube livestream[0], and got their Google accounts banned immediately by YouTube's spam detector. That means GMail, Google Docs, calendar, all gone.

That's the pragmatic POV. A little more future-oriented POV is to say hard no to all such cloud logins, because as implemented today, they're a stupid and exploitative idea. With the importance of digital SaaS to daily lives and businesses of so many people, we're allowing companies to create what's essentially a parallel system of legislation and national (fiefdom?) IDs.

The reality is that wages have never kept up with productivity increase. Companies are extracting more and more productivity out of their employees, which translates to ever increasing profits.

But this is not an economical law. It's absolutely possible to sacrifice ever increases in growth for more worker time.

This article makes the same mistake as the last one. The inner save and restore of SP for the variable-length array is logically disconnected from the function epilogue, and not part of it. In a more complex function the disconnect would be more clear.

They're already doubling-down on the forced integration. They replaced the Oculus profile-based "Friends" button on the Quest home with a "Chat" button that opens Facebook Messenger in VR. In my friend circle, nobody wants this. It gets in the way of starting party chats and sending game invites to Oculus friends, who (for me anyway) are largely a separate network from my Facebook friends.

Facebook is assuming that users want their gaming social networks and IRL social networks to be the same. This is lunacy. My Steam friends and my Facebook friends have been largely-disjoint graphs for decades, and for good reason. Imagine friending someone in a VR game, and immediately getting blasted with their political posts/family photos on Facebook. Imagine friending someone in a VR game, and suddenly they know who you are IRL (forever). Via people-finder sites like Spokeo or YellowPages, it's trivial to connect this info to your home address, telephone number, employer, and so on. What happens when Internet stranger who knows where you live gets mad that you won the rare drop and they didn't?

Forced integration of Facebook and Oculus is a safety issue.
When people worry about land-use of solar, I think about exactly this. There are large chunks of central Spain that would be largely improved by covering them in solar panels (joke, but only just in some places).
Some people do like to kill. I think taking this absolutist assertion that having humans involved in the killing will mean less killing is incorrect. Some people like to and some don't. Every person that has died in every war ever was killed by someone else. There are and were entire cultures dedicated to waging warfare. Lots of killers sleep better at night for having done it, some might not even be bad people.
Transaction fees for sums above lets say $500 are way cheaper than most banking fees especially assuming different currencies. Even more when we compare to western union or even paypal

Let me give you a real world example. You buy something for $10. Then ethereums $5 fee sounds crazy compared to 3% or so for creditcard or paypal. However transfer $1000 and those 5$ suddenly sound a lot better than the 30$ the creditcard or paypal charges.
I agree, but there’s this screaming cage match, euphemistically called “engagement,” that is the vein of gold for Web site owners.

As has become clear, “engagement” means public brawling. It generates clicks, and clicks are gold. It also encourages people to sign up for accounts, just so they can jump into the cesspool. Those accounts are quite valuable, as they are fodder for data miners, correlators, and aggregators. Making those accounts free, and easy to create (but not so easy to delete), is a natural.

That’s why so many of these sites wait until their comment fighting pits reach brand-destroying levels of rancor, before they do anything about it; sometimes, too late (remember when SlashDot was the HN? It’s now the place to go, if you want ASCII-art swastikas).

Yeah, I’m cynical.
The 'difference' is action vs inaction. I do not know what the consensus is, but we see this drama every 6 months. If they just said 'we are not going to do it', it would be one thing, but we have been having this charade for a while now. I know some charade is required to build consensus, but based on my reading of the news, there is just too much chatter, and we all get riled up every time we change clocks.

I think the idea that the pressure to produce your wine as cheap as possible is only there for cheap wines is fiction. For expensive wines the same pressure is there, they want to make a profit. So while with expensive wines, potentially due to the high price they might have the resources to do better, you have no guarantee whatsoever that they actually will.
> I've found that, to keep a balanced diet without meat, it's quite a bit more expensive, and exceptionally more time consuming.

Mass produced meat is cheap because you don't pay it in $ but in pollution and animal suffering.

I was a "ah whatever they're just animals" guy for a long time, but once you do your research it's basically impossible to eat cheap meat again. It's jot even a question of polluting less, it repulses me now

When the licence text contained "the Software is copyrighted and comes with a single user license, and may not be redistributed"² then it hardly meets the expectations people have of Open Source.

- Discover to the world by the Spaniard crew captained by Columbus/financed by the spanish monarchs.
