Yeah, it's remarkable. You'd think that "I'll buy your house immediately" should be at a worse price than the guy who insists on the old school inspection and due diligence.

In fact it might not be a bad strategy to simply start with that... see if there's desperate people needing the money fast, and use your corporate heft to both sweep up the deal (brand) and patiently dump it back into the ordinary market, pocketing the spread as a liquidity premium.

One thing I remember my first boss saying is that it's hard to get a good trade on. Attractive deals have several interested parties. If you're getting a lot of trades, they might not be good ones.
No no no!! Oh man, I’m really sad my comment invoked DK, I don’t think this is the same thing at all, and I have a strong dislike of this paper because it’s both misrepresented and almost universally misunderstood. (And the authors are complicit in encouraging this misunderstanding, because the paper made them famous.)

The paper did not show confidence being inversely proportional to knowledge or skill as many people believe. It shows a positive correlation between confidence and skill.

But the paper itself is very hyperbolic and draws invalid conclusions that are unsupported by their own data IMO. You should read the actual paper, it’s enlightening to look at what they actually tested, and compare that to how they wrote about it. They didn’t test high skill tasks. And they didn’t test incompetent people. They tested only Cornell undergrads who were volunteering for extra credit. They didn’t control for this completely skewed population sample in any way.

They also didn’t test people’s estimation of themselves either. Not at all. They asked people to rank themselves in a group of others, without knowledge of the others’ skills. This simply means people were guessing, not that they were overestimating themselves!!

This is a great post explaining what’s most likely happening with DK: regression to the mean.

In many situations it's much more an art than a science. Oftentimes you see "we multiplied independent variable X by independent variable Y and that is what we attribute this increase in Z to"...

But it's wrapped up in such complicated rhetoric that no one questions it (perhaps less cares...)

I shouldn't berate it though. It pays the bills..
Pretty much every IoT device uses Wifi, and that doesn't seem to be a problem right now. They all seem to be perfectly capable of speaking WPA2 with AES.
It’s not meant to prevent screen replacements, that’s the whole point. It’s meant to verify the chain of trust of the hardware involved in the security function of the device. If you move that from one device to another, you haven’t broken the chain.
I'd advice reading the famous article "More is different" by P. W. Anderson. It takes condensed matter physics as a counter example that knowledge is a pyramid, and that e.g. biology is just applied chemistry, which is just applied physics, which is just applied math and so on.
I am glad social science people do not need to know quantum physics, nor medecine does group theory ; their fields are dense enough on their own sake ...
what's the motivation behind this? why do they want to do this?
Your initial point was "It's almost like the existence of vaccines places evolutionary pressure on a mutating virus". That is implying that the existing observations could be explained by evolutionary pressures, not just that it might be happening in the future.

Delta would have been the dominant strain everywhere without the vaccine as well. Most of the reproductive advantage of Delta did not come from antigenic drift. Blaming vaccines for it like you did is completely, 100% false.

In a world with no vaccines, antigenic drift would happen just the same way, and still gain a reproductive advantage, just from evolving against disease-conferred immunity rather than vaccine-conferred.

> fail to deliver what academics call “social presence”, which is the feeling of being together in unmediated communication

Do they fail? I don't thinks so, when I e.g. play D&D like games over voice only chat + a shared map it totally convoys the "felling of being together" (just one of many examples).

On the other side when in-person sitting in a conference room where a person takes 30min to convey some (for me) mostly irrelevant facts which could have been summarized in a single slide there isn't really any "feeling together" and weather I'm sitting there or at home or use a headset on a train station makes literally no difference.

What makes people "feel together" is interaction and being focused together on a specific think. This doesn't need VR or AR at all.

Also what people totally forget is that moving company meetings and similar into VR has a number of problems:

- everyone needs to have a VR headset with them and a reasonable good internet connection

- everyone needs to be able to use a VR headset, but even with the best headset there are tons of people out there which get motion sickness from it (or from many things which convey 3D weather it's in VR or in a PC game) this people are much less rare then many thing.

- the platform needs to convey the feeling, as I mentioned above "just putting it in VR" doesn't mean it works. Also more important the "virtual venue" you meet has no reason to be anything like the real world, like at all. So there is no reason to replicate all the limitations from the real world. But Facebook seems to be exactly trying to do this.

Facebook positioned themself well by owning one of the most affordable VR headsets.

But the meta-verse thing isn't looking too good IMHO.

What companies want isn't a virtual world, but a virtual meeting room.

What people want is being whatever they want to be in VR, and potentially have different identities for different social cycles (mainly work, friends, family). So not quite what Facebook is building, to some degree even the opposite thing.
>However, the ability of people to build upon GPT-3 was hampered by one major factor: it was not publicly released. Instead, OpenAI opted to commercialize it and only provide access to it via a paid API. This made sense given OpenAI’s for profit nature, but went against the common practice of AI researchers releasing AI models for others to build upon. So, since last year multiple organizations have worked towards creating their own version of GPT-3, and as I’ll go over in this article at this point roughly half a dozen such gigantic GPT-3 esque models have been developed.

Seems like aside from Eleuther.ai you can’t use the models freely either, correct me if I’m wrong.
The announce of open-sourcing the RISC-V cores on which they have worked until last year was simultaneous with the announcement of a high performance server CPU using the latest ARMv9 cores, to be used in their data centers.

So, yes, I would guess that after playing with RISC-V for a couple of years they have switched to ARMv9 for the real thing.

One of the cores that have been open-sourced now was in 2020 the fastest RISC-V core ever designed, but for the best performance they had to correct a blatant omission in the RISC-V ISA and add a custom extension for indexed addressing.
Solar is not cost-effective today for applying power after the sun sets (duck curve) or at night. Wind is not cost-effective at supplying power on calm days. If they were required to build the rest of the system to be reliable (longer interconnects, batteries, etc) it suddenly wouldn't be cost-effective, this explaining why energy cost continues to go up while this supposedly cheap power ramps up.
If you lived somewhere rural, long distance charges were very limiting. Even a call to the next town could be a lot of money. So you would spend a fair amount of time figuring out ways around that. Open PBX's that would let you transfer to a dial-out, or dragging your computer to a library that had some unprotected RJ11/12 jacks, etc.
I think that if maintaining good sleep hygiene and diets have not helped for a long time, then one should probably start consulting a trained medical professional.

“Pull back the covers on large scale deep learning models and this is one reason overfitting creates miraculous accuracy. Large scale models have a primitive understanding of the deformations leading to a degree of generalization. The more the model learns about how the inference space changes over time, the better it generalizes.“

Pretentious mention of topology followed by super broad, almost completely incorrect characterization of the double descent phenomena, color me surprised.
You likely mean the nist post quantum competition, which is about public key encryption and signatures.

The answer is noone yet, it's still running. Here's the list of proposals currently in the competition: https://csrc.nist.gov/Projects/post-quantum-cryptography/rou...
> I guess if you ever need to match on a specific prefix storing the numeric IP might be an issue?

If you want to search for range, you can do:

SELECT INET_NTOA(ip) FROM ips WHERE ip > INET_NTOA(:startOfRange) AND ip < INET_NTOA(:endOfRange)
> Since virtually every value is going to be different, indexing and searching on that field is (almost) no better than having no index on the datetime field at all.

Do you mean exact equality is rarely what you want because most of the values are different?

Or are you talking about the negative effect on index size of having so many distinct values?

I think the latter point could be quite database-dependent, eg. BTree de-duplication support was only added in Postgres 13. However, you could shave off quite a bit just from the fact that storing a date requires less space in the index than a datetime.
The fact remains that whether the text column existed on her original table, or whether it was pulled out to a normalized table, literally all of the same constraints would apply (e.g. max char length, any other underlying limitations of indexing).

The issue is that her analysis of what the issue was with her original table is completely wrong, and it's very weird given that the tone her "present" self is that it's so much more experienced and wise than her "inexperienced, naive" self.

My point is that she should give her inexperience self a break, all that was missing from her original implementation were some indexes.
Lawyers don't give a hoot about the truth, they care about billable minutes and winning their cases, and if that requires bending, twisting or breaking the truth then so be it. If lawyers cared about the truth then there wouldn't be any lawsuits, just mediation and settlements out of court.
Both of your statements are factually untrue for reasons already in the source article. You cannot just swap parts from one phone to another. The entire point here is that you cannot harvest the most profitable parts anymore because they need to be keyed to the device. If you can’t do that, they’re worthless.
I was just going to make this comment.

Postgres as far as I know uses B-tree by default.

You can switch sort order I think for this as well, so "most recent" becomes more efficient.

Multi-column indexes also work, if you are just searching for first column postgres can still use multi-column index.
When extreme levels of wealth started to become synonymous with parasitic wealth extraction and the wealth was used more and more to buy political influence.

I suppose some people still look at billionaires as people who earn rather than extract wealth. It's a quaint thought.

I believe this functionality is provided by SyncTeX. I'm sure it can be used in other editors, but it can be accessed from the right click menu in TeXstudio.
> I suppose I don't like changing the use of language where "unknown" now becomes "unsafe".

I don't think that's changing the use of language at all. For example, playing one round of russian roulette is 'unsafe'; even though (a) we don't know if it will have a bad outcome or not, and (b) the chance of a good outcome is much higher than that of a bad outcome.
The real meaning being that people learn and gain experience over time? Is this really something we need to read two pages of text to find out? I think people are justifiably miffed at having read two pages for such a trivial message. Not only that, but these "stupid implementation details" could seriously mislead someone who really is a clueless newbie.
Just wait till Google realizes they can hire equally competent people overseas for a fraction of the wages and those people won't have any of the cancel culture tantrums American workers do.

It was like Discord servers today but slower, ASCII/ANSI art instead of images, and less real-time chat (although fancy BBS's with multiple telephone lines did have chat rooms).
OpenAI takes the Orwellian cake.
I've always wondered about that, did they evolve after the invention of houses?
Any bond trader can tell you that overall your model can have zero bias, and a small error term, but your bids that get hit and offers that get lifted are the ones that are "off". This could have been solved with a "human in the loop". Of course, that may have broken the economics of the entire operation.
Coding, I actually had to forbid it today in a course I teach because it solves all the exercises :) (given unit tests with titles students needed to fill those tests in)
Back before Micro Center or CompUSA we actually got a BBS list from the local library. On the East Coast we had Focke's list.

This is an interesting article from 1989 about the culture: https://www.washingtonpost.com/archive/lifestyle/1989/07/28/...
In Taiwan, one of the most popular social network is still a public BBS.

Honestly, the cyber life without any algo is fantastic!

Good catch. I bet you're right.

I'm a big fan of "Do your own damn homework."

OP can do their own research. That said it seems like there's plenty of peeps here happy to tell their stories.
Very true. Regrettably, janitorial work is extremely hard to publish, as I had to find out. Mostly because reproducing other people's work, or comparing methods, is bound to find unfavorable conditions where a method does not work as well as published, or error measures that highlight common problematic behavior. At least in my area of research, such findings were unpopular with reviewers, to say the least. Probably not least because the reviewers tended to be the very people whose work was reproduced.

Which is sad, because this sort of work is well-suited to get PhD students acquainted with a field, and provides real scientific information.
But what about the potential for intellectual property problems?
Can I suggest WebXR [0] and one of the popular Javascript frameworks like Three [1] or Babylon [2]?

The learning curve is a bit kinder and you will likely find some of the skills transferrable if you decide to switch to something beefier later.

Note: I'm no VR adept either, but I've enjoyed a little tinkering via this route.

I want to share data structures built for handling concurrency between threads. I'm less interested in having to "share memory" by message passing between places. Plus, places are more clunky to use compared to Racket's `thread`.
Luckily, there’s a jetbrains addon for it.
Someone at work showed me copilot works on WebStorm today (I also use VSCode).
Yeah. GameFAQs guides had perfect usability. Now they're multipage HTML documents and searching is impossible. Sometimes the "guide" consists of nothing but YouTube links.
Until it starts raining. The cost of keeping the water out of the battery will be very high.
We’re vaccinated, in a very low risk population, and have multiple homes to quarantine in. The net risk to mental health of not partying and going out is way higher than the low risk of falling ill.

Things that we didn’t account for:

- some of us had to miss Halloween, should account for social event temporal proximity

- we were able to quarantine together and spend time in each other’s company, so getting sick at the same time is the best
Many game devs, myself included, would argue that loosely coupled code makes for messier and less performant code in most situations. It certainly becomes harder to reason about code once the execution flows through dozens of different functions (often in different files) rather than through a single monolithic function. This is somewhat obvious when you think about it, yet people still insist on breaking long but perfectly readable functions into tons of tiny parts for some reason.

In many game dev circles there has also been a strong push towards “Data Oriented Design” where the focus is on manipulating the memory as directly as possible, rather than creating abstractions. See this talk by Mike Acton: https://youtu.be/rX0ItVEVjHc
I want to understand how the experience was
(this is "user experience" Sysop experience is different.

> what was the cost involved
For users the cost of a computer, modem, terminal software, phone line, and any applicable long distance. Maybe BBS subscription fee if it was some pay to use BBS.

> what were the entry barrier for an average person to join

Cost of a modem (before the VIC MODEM modems cost several hundred dollars, after that prices started dropping, but it was still as significant cost.

Long Distance charges - unless you were in a larger area with local and good BBSs you were calling long-distance to connect.

If living with others with one phone, you would battle for tying up the phone to call BBSs, so you would probably do it late at night like friday and saturday (not school nights)

>How similar was it to current social media networks

Think of internet usenet message groups or on-line forums for BBS message boards, email, and some downloading of programs and on-line games. Very few board were multi-line where there was more than one user so not much chatting, except with the Sysop occasionally.

> How big the industry around it actually become

Pretty big, at the high end there were mini-online entertainment services, with fancy multi-line chat boards offering paid content. some businesses had on-line ordering/support BBSs, as well as portals for say government clients to submit data, etc. News agency portals, etc.

From a tech point of view what do you think were the major breakthroughs and what made it to the internet we see today.

Electronic File Transfer (upload/download), Email, message boards, multi-BBS network data transfer (aka FidoNet), terminal graphics.

> I have watched the documentary www.bbsdocumentary.com , so I have some context but want some more anecdotes if I can :)

The hard part if you weren't a kid pre-internet, you dont know how compressed your world was. Back then communication was usually occasional phone with friends, face to face meetings (usually limited to your community's social group/neighbourhood), reading a lot of magazines, going to the library for information, lots of mail (catalogs by mail, order by mail) TV catered more to families and local grocery/clothing/appliances.

BBSs let you expand your reach for interesting/provocative information (see textfiles.com), a big part for me was communicating with other like minded computer geeks (not only nearby but in other cities or even across the US or even world - as a BBS sysop I had a few international callers no idea how much their phone bills were). There were also some less technically minded lonely people able to get on-line looking for connection (on-line pen pal, etc.)

That's my perspective,
What if one makes an small contribution through independent study? Will that be sufficient to be granted a Phd?

I do hear that some universities offer a PhD by publishing, wherein they grant a degree for already published work.

Perhaps a bit like the film making model whose name presently eludes me, where instead of trying to get a funding from a studio to make a film, the filmmakers make it out of their own resource arrangements, and later try to sell the finished film to studios (perhaps for a profit).
How it works - get a threadwatch.xyz link, post in the twitter thread of your choice and wait until threadwatch finds and posts your link.

Hi HN! Earlier this week I had the idea to gather a lot of 'fiery' discussions on the internet (twitter for now) and see how I could go about aggregating/ranking them. This is the result of that! Let me know what you think and any features you think would work. Going to continue working on this for the next week or so.
Actually using this class (larger transformer based language models) of models to generate text is to me the least interesting use case.

They can also all be adapted and fine tuned for other tasks in content classification, search, discovery etc. Think facnial recognition for topics. Want to mine a whole social network for anywhere people are talking about _______ even indirectly with very low false negative rate? You want to fine tune a transformer model.

Bert tends to get used for this more because it is freely available, established and not too expensive to fine tune but i suspect this is what microsoft licensing gpt-3 is all about.
Yes, the proposed ‘better’ structure basically amounts to building your own indexes. Normally, I’d assume it is better to use the RDBMS’s own engine to do that, don’t roll your own.

There may well be some subtlety to the indexing capabilities of MySQL I’m unaware of though - could easily imagine myself making rookie mistakes like assuming that it has same indexing capabilities. So, to the post’s point - if I were working on a MySQL db I would probably benefit from an old hand’s advice to warn me away from dangerous assumptions.

On the other hand I also remember an extremely experienced MS SQL Server DBA giving me some terrible advice because what he had learned as a best practice on SQL Server 7 turned out to be a great way to not get any of the benefits of a new feature in SQL Server 2005.

Basically, we’re all beginners half the time.
Some people always seem to be in a rush to forget the humanity in people they disagree with so they can justify letting them die in ways they would consider murder if the tables were turned. It’s like they think they’ve found a loophole to behaving morally or ethically that they think society won’t judge them for.
FirstClass was amazing. I saw this thread and immediately searched in it to make sure someone referenced this incredible piece of software.
Same reason as anyone to open source anything?
This is the good way to deal with this. Front and center.
Quite a few TeX-oriented editors support something like this; a couple that I've used personally are TeXShop (macOS only), TeXworks (cross-platform). Searching for "SyncTeX" suggests that others such as TeXnicCenter and TeXStudio also support it.
Based on my experience I disagree. If there is a native data type that represents your data, you should really use it.

It will make sure that incorrect data is detected at the time of storage rather than at some indeterminate time in the future and it will likely be more efficient than arbitrary strings.

And in case of IP addresses, when you are using Postgres, it comes with an inet type that covers both ipv4 and ipv6, so you will be save from requirement changes
What a bizarre post from an influential blogger so confidently making assertions that are wildly contested even among HN users.

If anything this is the problem with industry, articles like this that make vast generalizations from a specific instance, unsubstantiated finger-pointing gestures, and passive aggressively blame the industry as a whole.
