The biggest problem with videoconferencing is using movie video codecs (designed for maximizing compression, and not for multicast latency control) tuned/tweaked for the worst client. So the typical video conference server uses a hand tuned gstreamer and a mechanism for requesting key frames at the pace of the slowest client. That work okish for up to few hundreds of connections in the case of all peers having quality connections (fiber). Scalable video conference, with e.g. thousands of concurrent clients require a different problem approach, being solved eventually because of specialized video hardware acceleration in the video conference gateway server, changes in the network infrastructure, and also low latency devices at client side.

I don't know, I suspect this is because there's so many weird sounds that aren't really explained in a course. I find if you look up a linguistic explanation of the language you see a lot of things that a language teacher wouldn't give you. But of course that's not the same as practicing.

I think I am missing the core concept here. This still uses IDs, only now you have to grep them out of a URL construct instead of just getting them directly?

I don't get the intent at all here, but I have a suspicion whatever problem this tries to solve is better solved by UUIDs or by doing nothing out of the ordinary.

Yes gambling and predicting are interconnected. They both share a common history.

Tomorrow the sun will rise. I do not know, it is just an assumption. But, I am quite certain of it. :)

> we assume that we can accurately forecast what happens in 80 years.

Nobody assumes that. Nobody forecasts the weather in 80 years. What scientists forecast is climate changes not the weather.

In the casino I cannot predict which players will win and which lose (weather). And yet I can predict that they will lose on average and the casino win (climate).
How to Save ~1GB Memory on Jetson Nano by Installing Lubuntu Desktop
While I like it too, it has some issues in practice, the biggest being that it works best with standardization: E.g. there's a few common types of beer bottle, and the idea is that you can ship bottles to whatever is the closest brewery that needs bottles and they can use them. That of course breaks down if breweries do their own, custom bottles, because now you have to filter those out and ship them to their specific brewery, which a) increases processing effort and b) means shipping empty bottles over longer distances (and in the US, the distances would potentially be way larger than in Germany).

That said, I think seating pitch and spacing is definitely a conversation that needs to be had. I'm an average-sized guy, and I have a hard time with today's airline seats.

Poor connections are a bit irrelevant though for the purposes of ranking URLs by page load time. Presumably whatever bot google would use would have an extremely fast connection, so if the bot loads it faster than X where X is reasonably selected, then it could be considered "fast". Percentiles might make even more sense here -- if the page is in the top 5% of all pages in terms of short loading time, then it is "fast".
Not quite if I am to believe other HN comments. The thing MCAS compensates for is that, in certain cases, as you pitch up more, the pressure on the stick decreases. This feels to pilots like leveling out, which is dangerous. MCAS was designed to counter this.

The specific design of MCAS and not adding any new procedures, was to lower the training requirements. Specifically, anyone certified on the old 737 was still certified on the max.

If they had improved the interface of MCAS and changed the procedure for runaway trim, it would have required more training. However, without MCAS or another remedy for the 'decreasing stick pressure at increasing pitch' problem, the plane would not have been allowed to fly at all.

> So either MCAS needed to have more limited authority over trim, so it couldn't cause trim runaway, or it needed the safety features of a Level I system.

There are two other dodgy things going on. One you can't disable MCAS without totally disabling the electric trim. And the mechanical advantage of the manual trim isn't sufficient to re-adjust trim once it's too far out. And hasn't been _forever_.

I would say "it depends". I have seen when replacing bunch of joins with sub selects improved performance. I have seen otherwise as well. It all depends on the nature of your data, RDBMS you're using and statistics it has accumulated.

I haven't seen anybody hitting "in" clause limits in query like mine but we did hit such a limit once when we were passing a hardcoded list of IDS from client side. Something like "where blah in (id1, id2, id3.... idn)". I remember that one failing on MS SQL.
I understand geo codes as a better positioning system. If i want to describe i dont have to describe e.g. in a park very ambigous because there are no clear points. I can say i am at e.g. „house flower car“ and they can find it easily by translation to gps coordinates and showing on a map.
That people don't really want it.

As far I can see it is possible and good enough today with Skype, FaceTime and so on plus a good internet connection; yet people prefer email, chat, telephone ...

Why should I trust you or FAA that the engine, the engine mounts and all the new updates related to this larger engines were tested when we know from previous articles that hings were rushed and stuff like the fire suppression system was not OK and the engineer was changed because was objecting.

I imagine that putting a larger engine is not as easy, isn't a larger engine heavier? the forces larger? Don't you need to test the engine supports, the wings, all the related mechanical support structure.

Your theory that only MCAS is an issue is already false since it was found that without autopilot 2 humans don't have the physical force to control the plane , so probably a new requirement in the FAA should be added that with autopilot off 1 single pilot should be able to control the plane. You may say this is related to MCAS but6 it is obvious that this item was not in any checklist for things to test so even with a working MCAS but other emergency where autopilot would be turned off you would get in the same situation.
What do you mean by "earth moves" do you mean tectonic plates ?

Wouldn't that apply to any of the other global location descriptions (GPS coordinates) as well? And is this really less permanent than street names/numbers that may be changed several times over the course of a few hundred years?

If you are going to describe a path to an ancient tomb, Indiana Jones style, than the movement might matter but over the timespans this system is used I don't think earth movement is an issue.
>> The energy cost ...
> This is a specious argument right from the start. Recycling isn’t about energy cost at all. Energy isn’t about to run out, we have solar, hydro and wind in the future. You can make backward facing arguments about coal use, if you want, but a strong argument would consider what’s already happening and what today’s trends imply for the future.

If we use plastic bags instead of paper or cotton ones we’ll use tens to hundreds of times more energy. Whether you think it’s backwards facing or not, in the present huge amounts of that energy comes from burning fossil fuels and the energy that doesn’t come from fossil fuels needs resources to be produced, it doesn’t appear ex nihilo. Solar requires minerals to be mined and hydro requires land be flooded and dams built. Everything requires resources, which costs are real, not fictitious, whether denominated in dollars or kilojoules.

>> paper and cotton use much more energy and water
>Why worry about the two things we can renew, while ignoring plastic’s use of limited non-renewable petroleum, or the fact that plastic production produces carcinogenic pollution and poisonous byproducts?

Because energy isn’t free any more than the land for growing cotton or trees is, or water pumped from aquifers is. Paper and cotton production is also not without its own chemical waste and uses far, far more water than making plastic bags does.

>> Glass and plastic containers reuse is a solved problem. Put a big deposit on containers and they’ll be reused.
>So you mean it could be a solved problem, right? I’m in favor of requiring deposits! If only we actually did that everywhere instead of passing out free single use plastics...

Yeah, if there was political will to do so it could be done in months not years. When things don’t happen because voters don’t want them that’s democracy.
Show HN: Tabtation – A Chrome Extension to Manage Your 'Too Many Tabs Syndrome'
Hey there, HN!

My name is Rishit, and this is my first post here on HN.

Let me start off by asking you a question.

How many tabs do you have open in Chrome right now?

If you said less than five or ten: Congratulations, you’re not suffering from the dreaded 'Too Many Tabs Syndrome' (TMTS). Well, most probably! We all grow and start from zero.

What?! Say that again. Did I hear you correctly? 25? 50? 100? Maybe even more? Or you’re just too lazy like me and said ‘too many’ since you can’t count them on your fingers? Woah! Now we’re talking! Yeah, yeah, I know, we’re in HN land after all, so I may be over-hyping this.

But seriously though, you must have landed up in situations where the tab widths are so small, you can’t make sense of anything. So, what do you do? You start opening new windows. Wonderful. Few hours of work, and yup, you end up with the same thing again. Windows are nice. But a lot of them (with a lot of tabs) sucks even more. I just went through all of my five windows and all their tabs, and still can’t seem to find that one tab! Jeez. ️

So, I may have something that would be right up your alley, and help you manage your TMTS; Well, it certainly helps me with mine, so I’m stoked to find out if it does the same for y’all.

I’ve just launched Tabtation on the Chrome Web Store!
(https://chrome.google.com/webstore/detail/tabtation/hdidaidp...)

I’m offering a 7-day free trial, so give it a try and do let me know what you think! I’d love to hear your questions, thoughts, or feedback, and work on them to improve Tabtation so that we can all be more productive in the coming months. ️

BTW, Tabtation is also on Product Hunt today (https://www.producthunt.com/posts/tabtation). Yup, a lot of firsts for me today!

Cheers!
Personality psychology:
https://en.wikipedia.org/wiki/Personality_psychology

There are a number of studies which identify a set of features and then search for clusters / 'categories' with various methods.

https://en.wikipedia.org/wiki/Linear_discriminant_analysis

> LDA is also closely related to principal component analysis (PCA) and factor analysis in that they both look for linear combinations of variables which best explain the data.[4] LDA explicitly attempts to model the difference between the classes of data. PCA on the other hand does not take into account any difference in class, and factor analysis builds the feature combinations based on differences rather than similarities. Discriminant analysis is also different from factor analysis in that it is not an interdependence technique: a distinction between independent variables and dependent variables (also called criterion variables) must be made.

There are plenty of reasons why reference counting keeps losing to tracing GC since the 70s. Swift is not doing any breakthrough to any of the variants that came before it.
a change that necessitate a URL schema change would be just as far reaching had the system been designed with using IDs.

For example, if the entity ID changes from being an integer, to being a GUID, you'd still have to write code to update your schema (presumably, from an int column to a GUID/string column).
Sendgrid is usually spam or redundant notifications, depending on host they might not make it through without manual whitelisting. Additionally, using a totally unrelated SMTP rela to deliver mail defeats much of the point of a self-hosted mailserver, you'd be better off using your local network's SMTP relay.
But those places are less in some places than others. I'm in Norway. I live here, and it isn't like I can just go to another place that speaks Norwegian. Children start learning English at age 6. Most adult English-language television has subtitles instead of dubbed: Console games are in English most times. Advertisements have a mix of english and Norwegian.

People are quick to use English. Very quick.

The main portion of the population that doesn't do so well with English are older folks, in my mother's age group or older. I also have a very good chance that the person I'm speaking to can understand english even if their speaking skills aren't the best.

Immersion simply doesn't happen the same here.

The public have consistently chosen the cheaper but slightly worse option for decades of technology. This, more so than engineer skill, puts an upper constraint on reliability.
The fact that JSON is just a format standard and doesn't have specified components (like links etc) but instead we have to built those on top has cost us a lot in APIs. Btw, according to RFC 8288 Web Linking (and before that 5988), a link consists of 3 parts + 1 optional part:

"In this specification, a link is a typed connection between two
resources and is comprised of:

o a link context,
o a link relation type (Section 2.1),
o a link target, and
o optionally, target attributes (Section 2.2).

A link can be viewed as a statement of the form "link context has a
link relation type resource at link target, which has target
attributes".

For example, "https://www.example.com/" has a "canonical" resource at
"https://example.com", which has a "type" of "text/html".

"

That's why you need a standardized link component that is globally accepted/understood that takes into account all parts of the linking, instead of having various ways depending on the API/JSON-based Media Type to communicate that something is a link.
According to what? There are plenty of fairly trivial counterexamples to this. If what you say here is correct, what is mental illness? What is a solid marriage vs a terrible one? What is a good job vs a bad job?

For instance, lots of peoples' mental states improve when they are able to not live with their parents, for various reasons. That requires money.
> This feels to pilots like leveling out, which is dangerous. MCAS was designed to counter this.

Pilots are trained extensively not to trust what motion feels like, and to use the horizon and instruments. An adjustment in stick pressure is not a notable new threat, they just need to be trained for the plane's behavior.

Another formulation of the "learning as a team" idea-

The science principle of publishing your experiments, including failed ones, has the same benefits in sw engineering: others can build on your failed attempts, or save time by not replicating them.
Recycling works- for high energy artefacts. Producing steel, glass, aluminium - takes enormous amounts of energy. There recycling is common place.

The real trouble is - plastic packaging, especially if the food contained went to a bio-methan operation first. The packaged food is shredded and added to the fermenter- this is THE topsoil contamination source of microplastics.

Its really tough to get plastic seperated cost effective.
> The owner object should have the invoices url for that owner available in the body of the owner object.

Actually, it doesn't need to. The owner object would only have invoice IDs. The invoice collection resource would be discoverable through the root endpoint through the same process used to discover the pet and owner collection resources.

In fact, the owner doesn't need to have any invoice information at all. The invoice collection endpoint can simply be queried to find an invoice related to the pet and/or owner.

> ...Its ludicrously bloated and part of the reason why no one does "real rest."

Actually it isn't, and the main reason why "no one does real rest" is because web API clients are required to perform content discovery, which is more complex than simply using hard-coded URLs/URL paths.

Of course this complexity is only apparent and superficial, as having to support a myriad of API versions ends up with a simple solution that due to all the technical debt that piles on rather quickly is far more complex and error-prone and unmaintainable than the approach required to do REST.
There’s a pretty vocal group that favors GitLab, I campaigned for it internally at a few companies as well - having so much of the tooling in once place is pretty nice. It’s obvious that GitLab is making quick improvements consistently.

The project boards are better than most others, the CI is phenomenal, and I have noticed the review process is being worked on.

Keep up the good work, we need options in the space!
That’s a very Linux-centric view. Neither of these works on BSD. It’s probably fine if you’re writing scripts that only need to run on Linux, but I wouldn’t call it the “right method”.
They should also announce a new aircraft design, a full replacement that is from blank canvas. There might not be that many sales in the sector if the humans are going to take climate change seriously but we all know that isn't going to happen and that Boeing need a fresh design.

The fresh design could tackle problems such as noise in a new way in order to get new customers.
Well it is all about how high one wants to set the bar.

Those examples are from 100+ years ago.

Chigorin is a promising counterexample but there are a few caveats.

He learned the moves at 16, late by modern standards and supposedly only got serious at 24.

We really do not know how much intensive/deliberate study he did ages 16-24. That is the big question. Same goes for Salwe.

So while Chigorin is a relatively late bloomer he still falls in the starting to play chess in his teens category.

I mostly concur with Polgar experiment with the addition that you have to start early.

If age was NOT a factor there should be very strong players who started late after age of 25 put in their hard 5-7 years and became at least an IM.

The majority of motorcycles are not very noisy in stock form. The issue is with absurdly loud aftermarket exhausts.

So increasing registration tax based on noise level won't make much of a difference. You have to go after the aftermarket stuff.

I've had a really noisy bike (loud exhaust installed by previous owner) and a completely stock bike after that. I vastly prefer the stock exhausts. Quiet most of the time, made a nice sound when I really gave it the beans, but nothing excessive.
