Meetup and AirBnB are the two companies that made the most profound positive impact to my life. They allow me a type of lifestyle that would not be possible without them. Travel around the world, stay in places I like and meet like-minded people.

I couldn't say which of the two companies creates more value for me. So it's interesting to see that one is valued at $20m and one at $1B.

Is the recent Meetup redesign related to the acquisition?

The redesign made the site so much worse. The UI became confusing. You constantly get 'keep waiting' spinners. And the look is kind of cold and harsh now. Would be funny if the new management style directly shows itself in the style of the site.

It will be interesting to see how Meetups journey continues. I hope it survives the new management. It's such a gem.
> Mode X is actually similar in some ways to the Amiga's bitplanes because it uses a planar memory arrangement.

Mode X does not separate bitplanes. With Mode X, you don't need to write to 8 memory addresses to completely change a single pixel. (In the worst case, you needed one slow "out" and one fast "mov" instruction, if you wanted completely random access. However, no one ever did this, because you could simply draw every 4th pixel once for each bank, requiring just 3 (or 4) bank switches per frame.)

Mode X is nothing like Amiga bitplanes.

Also in Mode X each byte does correspond to a pixel on screen, it's just banked in 4 banks.

Mode X it interleaves framebuffer pixels into four banks. Top-left pixel at coordinates 0, 0 is in bank 0, next right is in bank 1, etc. until pixel at coordinates 4, 0 is again in bank 0.

You could also write same pixel to all banks at once (or in any combination).

On Amiga, bitplanes worked very differently. They were basically layered "2-color" bitmaps, one bit corresponds always to one pixel. 1 to 6 bitplanes (or 1-8 for AGA) could be combined to form 2^1 to 2^8 colors. So for example for 256-color display, you actually had to set eight bitplane pointers.

This type of bitplane arrangement made setting a single pixel very slow. You had to rotate desired color value bits and mask & set corresponding pixel in 8 different memory addresses...

Everyone has a balance of these things, but in my experience there are two extrema to approaching maths. Some people are happy to be solving the puzzles, and simply enjoy the thrill of the chase. Others insist on knowing why they should be learning this, and what it's good for.

Both are valid, but if there is A and B and you're naturally good at A, the natural tendency is to ignore or avoid B. But that then limits your box of tricks, and makes you one-dimensional. By all means take advantage of what you're good at, but work hard on the other aspects to enrich your abilities. Also, they cross-fertilise, so you get more than you might expect.

With regards your oldest, it's worth trying a bunch of stuff to see if you can work out what they prefer. Then do both, but be prepared for having to work harder on one aspect than the other. Your oldest might like puzzles for their own sake, or might insist on knowing what it's for. Explore both. Find maths in strange places, work through puzzles just for their own sake.

The critical key is to be doing stuff all the time.

Without even looking at a phone keypad, how can this make sense? The 3rd and 4th characters can't both be O if they come from different keys. Perhaps they mean 32665?
GoboLinux is incredibly interesting, along with GuixSD and NixOS, which are the three best things to happen in the Linux sphere I guess. GuixSD is my favourite, but it's full GNU, so I can't practically use it (missing drivers in kernel and maybe X, need to compile often). Nix has a funny language and systemd, so not really an improvement over Debian for me. Maybe I should try GoboLinux instead, but I'm afraid that there will be too many packages missing from it and IDK the story with security updates.
That's the key idea - they will continue to do M&A to get advantage in tracking and exploring user behavior.

> Oh god, please don't, at least not for chat/irc/whatever-you-call-it. I've seen so many attempts to try to somehow add another layer of order on top of chronological order.

Like threads in e-mail, Usenet, forums on WWW?

IMO those are perfect examples of a combined logic and chronology. I'll speak for myself, but I absolutely prefer threads in the mentioned examples. It makes the content better readable. For me, there's no question about that. Although that isn't any proof; it'd be best to have usability studies about it.
Not this excuse again. Everything Facebook has ever been caught doing maliciously was classified as bug - at least until they turned it back on later and called it a "super important security feature the world couldn't live without -
so, you're welcome?!", like they did/are doing with the datr cookies.

They're also going to get caught using people's supposed "face authentication" biometrics (another recent "security feature", which btw is a stupidly reckless feature even when taken at face-value, because biometrics should be stored client-side not in a centralized database where millions of profiles can get hacked at once) for 100% advertising purposes, and they'll probably call it a bug again if there's strong backlash against it, at least until they make sure they can't get caught the next time they do it.
I think the key thing for making math worth knowing for a kid is making him realize that world is full of numbers.

One way I intend to do that is providing kids with a lot of measuring devices as toys. Rulers, calipers, pirometers, timers, you name it. If it can give you number for something real then it's a good toy.
"Which brings me to the question, why for these studies it is always so desirable to find out the increase in risk of a single factor. "

I would say remains of Descartes etc. The (outdated) philosophy, that everything can be broken down to single factors and then correctly calculated ...
It took science some time to realize that the world is too (infinite) complicated to be calculated.

It surely helps though, to know the probable impact of single factors. But I believe we still generalizing way too much. Fat is bad, Sugar is bad, Cholesterine is bad (no wait good), Alcohol, smoking etc. ...

Which, I believe is stupid, when humans are complex and
moderation and balance is the key. (even smoking can be beneficial I believe, for certain people at certain times, not as a addiction, obviously)

So seeing those single factors from studies help us as guidelines, but shouldn't be taken literally.
I was wondering why they don't use old style phone boxes with new tech inside. But of course, someone will piss, take a shit or do drugs inside. Great way to ruin it guys.

It's actually less about insulation and more about air sealing. A hermetically sealed home with no insulation is generally warmer than a leaky home with walls stuffed with insulation.

Also regarding wood, this isn't the kind of wood you're thinking of. It's called pressure treated lumber, and it's an order of magnitude stronger than normal wood. The lumber has preservatives injected specifically to prevent rot, insect damage, and fire resistance.
You can still choose which companies you interact with. That doesn't prevent the government from getting your data, but it does mean that those companies won't be able to use it for their own gain.

"Homework" is supposed to be practising skills they have already learned so they can make it more fluent, and have to concentrate on it less when they come to the next thing to learn. Learning things is done with the teacher there to help anticipate, identify, and correct misconceptions.

If you want the parent to help with the homework, the parent will have to know the material they want to help with. In maths, that's rarely the case unless it's the same thing they learned. And that's now out-of-date.

Parents say they want their students to learn new, modern maths, and then insist that they are taught exactly what they were taught. And hated.

Having said that, I'm really not going to defend anything about the existing setup and system. This is a huge mess, and while I have my own ideas, there's no way a discussion here will change anything, and it's likely that things I do say will be taken out of context, twisted, and mis-understood.
But not with that pesky so-called "Charter of Fundamental Rights" that keeps forcing them to slightly update their mass surveillance laws every couple of years, as they're ruled invalid...again, and again.

It's why the cons have intended to switch to UK's own "Bill of Rights" since Cameron.
You have to treat it as a separate system. Kind of like apps which have their own gem/npm/pip ecosystem. It's another list of versions to pay attention to. It sucks, but not worse than having another VM.

> While photons normally have no mass and travel at 300,000 kilometers per second (the speed of light), the researchers found that the bound photons actually acquired a fraction of an electron’s mass. These newly weighed-down light particles were also relatively sluggish, traveling about 100,000 times slower than normal noninteracting photons.

300,000 / 100,000 = 3

"Relatively sluggish?" That seems more like profoundly sluggish, for light.
Companies like Google or even Mozilla can easily ruin or at least make it harder for social networks to track you and your interests with their browsers. You already have "block thirdparties" checkbox and similar restrictions, soon you will be provided with builtin ad-blocking. Sounds bad for all social networks and tracking services.

So Google has everything in his pocket, but if FB really has something to put against?

Yea, support isn't first class. When I was learning to use union types in TypeScript, initially I wrote custom type guards to distinguish them, using any property that was unique to a particular constituent type to differentiate them.

Nowadays I consider that a mistake, and all unions have a discriminator property, and there is no need for custom type guards (exceptions would be when writing .d.ts files for JS that uses them untagged, that sort of thing) since it makes the code much more explicit.
Bricks and concrete are absolutely not the best. They have terrible insulation properties, poor sound absorption, and cost more than wood structures.

Wood is an overall superior construction material if you can use it, and I think you're misunderstanding the pressure treatment process. It's normal wood placed in a vacuum chamber so preservatives can seep into the lumber.

Obviously Eric wasn't creating the inventions himself, but I would argue that he fostered innovation very effectively in the way he ran the company. Eric hired amazing people and put them into an environment where bottom-up innovation could happen, and then he stood back and let it happen. It was chaotic, but a lot of great stuff came out of it.

OTOH, when Larry took over, things became much more top-down, with Larry trying to be Steve Jobs and tell the company what they should be building next -- most notably when it came to Google+.

I left before Sundar took over so I don't know how he runs things, but it seems like Google these days is just sort of chugging along, building solid products but not doing anything revolutionary.

Very interesting! But there is quite literally zero cross-bracing in that structure, which leads me to believe this was designed by an architect and not a structural engineer.

The Quorn revolution: the rise of ultra-processed fake meat
This article itself never mentions complaints about money. It reads to me that some employees don't want to accept the revised growth focused values, thus getting let go and still felt salty/betrayed about this.

If the culture will be gone no matter what because of the company's own reality, and they refuse to accept such changes, isn't departure an inevitable outcome?

> What makes you think there is anything there to appreciate? As best as I can tell it's just random sounds and words.

It isn’t "random sounds and words". While Joyce chose to make the surface of the book a constant stream of puns and other wordplay by drawing on a large number of languages, Finnegans Wake has a character, story, setting, etc. like any other novel. I personally find the Wake tiresome – who was the contemporary of Joyce’s who called the book something like an “electrified punning machine”? – but "Emperor’s new clothes” it definitely isn’t.
> You can still choose which companies you interact with.

Right, which is my point. They won't mind something like limiting access to college women to those with good scores like America would, so they won't take their money elsewhere. Their different culture causes companies to behave differently than they would in the US.

I don't know if these phone boxes will last for long, there have been plenty of efforts to repurpose them for free wifi, maps, local council services and so on but these experiments never last for that long.

The fundamental problem is the guy with the iPhone X has a contract for lots of 4G bandwidth and would prefer to just use that except for at home/work when the wifi gets used.

So you are left with customers for the service that have pay as you go SIM only contracts for an old iPhone 4S.

Gambit-C [0]. It's a R5RS Scheme, and is near-C level of performance. It compiles to C, so embedding it is fairly easy too. Compiles to static executables, which is easy for distribution.

Chez Scheme [1]. It's a R6RS Scheme, so bigger, but Chez has much better embedding support, is backed by Cisco instead of a single dev. Chez doesn't make standalone executables though, because Chez is jitted. It may be the fastest Scheme. It also includes a compiler, a profiler, a great debugger, live memory-introspection, and an enhanced REPL [2] that can dump out it's definitions and any comments into a lovely Scheme file.

Good question. Many people really don't like the incredible amount of cultural and political influence that these large multinational corporations are obtaining through data collection and analytics. This is just another example of corporate influence extending further into aspects of society that were formerly handled by the government.
But if they're so confident in the disk, then why do they checksum the metadata? They should either trust the disk and have no checksums or not trust the disk and checksum everything.

There are plenty of other reasons not to checksum user data, as it's a choice many have made, but that they trust the disk is an invalid argument.
Regarding a), it very much depends on how they are built. Little Moreton Hall has been standing since 1504, subsequent restorations required no changes to the timber structure. Isn't it beautiful? Although I suspect it is definitely subject to point b)!

A lot of Matrix.org is inspired by what Wave could have been - although we are running late with threading (but some work is happening currently there). From our perspective, one of the biggest gaps was the lack of bridging in Wave to other existing comms interfaces (eg email) - as well as the quirky UX.
It is a nitpick for sure, but I am still amazed that a machine like this, obviously designed to be the best and look (and cost) the part, comes with a measly 1 year warranty out of the box. It takes away from the feeling that Apple has confidence in the product, imo.

For reference, European regulations will force them to upgrade that for free to at least 2 years, which is deemed a 'normal life time'.

Honestly, the slide deck to me looks like a positive and important correction from a company that's been too lax and directionless in its management (this is an inference - I don't know anything about Meetup specifically). It's not contemptuous, it's honest and direct. Most companies would not be so honest with everyone about seeking a change in direction like this.

> Past: We debate too much without defined decision makers and don't act on decisions

> Starting now: Clear decision makers end the debate, communicate the decision, and act quickly

> Past: We wait too long to take action when someone isn't meeting expectations

> Starting now: We take actions fast and say goodbye when someone isn't meeting expectations

Someone who has been a manager for years should know how poisonous it is if people can't make a decision because they are overly focused on consensus and there is no clear decision-maker; and they should know how poisonous it is if people keeping debating the same decision after it's been made, and don't get on board with implementing it.

Lack of accountability is similarly poisonous, and lack of initiative is problematic. Letting poor performers stick around too long is poisonous (it demoralizes everyone else). These and other principles in the deck are part of the basics of good management. I don't see much to object to in here.

The slide deck makes it seem like this is an organization with a (management) culture that's gotten fairly far off-track from focusing on building a successful, thriving, growing business. Senior leadership is trying to course-correct. This slide deck is a nice way of communicating "we have a serious culture problem and need to fix it".

Managers who are achieving success and have not fallen victim to these anti-patterns probably don't need to change anything because they already understand the lessons embodied in these slides. Hopefully those managers are rejoicing because their ineffectual peers are being steered in the right direction now.
Researchers are struggling to replicate AI studies
This definitely matches my understanding. It seemed like a glorified demo, something developed in a bubble. Which is fine if you want to make a tech demo. But it's a terrible way to make a product that people actually adopt.

I have to suspect that nobody on the team had ever read Crossing the Chasm; if they did, they would have know that technophiles are a very small percentage of the market. If we want broad adoption, we a) have to solve an important problem for early adopters, and then b) broaden features and approachability enough that the majority of users will switch.

As the article points out, this is worse for network-effect products. Maybe interoperability would have helped. (And maybe not; Slack didn't bother with much of that.) But I don't think it was the primary mistake they made.
