Agreed about London vs. the US, and the same would hold for Paris, but Berlin is the exception: apartments (and expectations) are huge compared to any other capital city.

I'm not sure why that is. Being physically cut off from the world helped keep prices down for sure, but it doesn't explain why apartments are large relative to the number of bedrooms.

Not only that, sometimes we do forget how sonething used to be called, or we only learned the expressions in the context of the foreign language.

`gq` for re-wrapping a visually selected block of text (<shift>-v is simplest) to your text width.

People have some interesting presumptions about AR/VR:

- participants will predominantly look around in 360 degrees

- participants will be manipulating the objects they’re seeing projected in 3D

- participants will have prolonged engagements with virtual objects

- all people present in the room will also be interacting with the same virtual objects

If these are all true then your analysis is correct: headsets are the only way.

If all of these presumptions are at least somewhat false then handheld “opera glasses”-style AR experiences will be very popular.

Personally, I think even people who have headsets and spend a lot of time in VR will also use handheld displays, for transient use and when others are present.

To expose this code from Rust to Python, there are a couple of different approaches you could take. The simplest approach is to expose a C ABI from your Rust program.

The big problem with this approach is that this limits us to a C ABI. Both Rust and Python are safe languages and requiring going to a lower level C library interface adds a lot of extra complexity and potential for errors.

The PyO3 project aims to let you have full access to Python programs from Rust. This includes both embedding Python in Rust programs and creating Rust extensions that can be called from Python.

So I have a question somewhat related to this that I never knew where/who to ask (well actually I asked a few mathematicians at a university I work with whose answers I couldn't understand - their answers were almost as impenetrable as the Wikipedia page, and some engineering scientists who I thought would be more into 'applied math' but they didn't know. So I'm hoping some data science people reading this would better understand where I'm coming from, and be able to explain at my primitive math skills level).

So, some time ago I contracted out writing some code for fitting a logistic regression onto a given set of observations. There were some specific requirements, but I think I should have been able to piece something myself together using mainstream LA libraries; some of them even hint at 'you could fit a logistic regression using these functions' but no complete examples. But I didn't understand well enough so I contracted it out.

The woman who ended up writing the code used a 'Hessian' matrix to do so (she actually wrote two functions doing the same thing, one used this Hessian approach - I think the idea was that it would be faster but there wasn't a lot of time and it never got tweaked enough to make a difference).

So my question - is there a layman's explanation for what a Hessian matrix is, and how it applies to fitting a logistic model? Also (with an eye to the future of my project), does it have applications for non-linear regressions?

Alternatively, are there any books where this is covered? I have most standard stats/applied stats/operations research books, as well as a few like the no bullshit guide to linear algebra, but none cover this specific issue - or even how to fit a logistic regression at all, on a practical level (so not just 'conceptually you do xyz, implementation is left as an exercise for the reader').
Some people are, and some people think the opposite.
No, my entire point is that the articles misleading headline makes the rope sound like a minor detail. We agree that the rope is much more than a minor detail. My point is that it's suspiciously omitted from the title.
As an early player of Pokémon Go since the release day, I can say that the whole game was poorly managed (and still is). Even after the initial spike of users, they can't do a major event without messing it up:

- https://www.theverge.com/2017/7/25/16019404/pokemon-go-fest-...

- https://www.destructoid.com/niantic-is-handling-pokemon-go-p...

The people who play Pokémon Go nowadays, they do it for the novelty of being Pokémon, not because it is a good game. Also, Pokémon Go is popular the same way Flappy Bird was popular: it's an effortless game to handle and it's very convenient to play when you already spend a lot of time on the phone.

Niantic managed to turn a multi-billion dollar game into a multi-million dollar one.

I don't know what is your position both in life and financially but sounds like you don't really care because you can tolerate risk and losses?
Yes, it can simply point to the different capabilities of human vision vs. the photo camera. So this explanation from the article appears to be false:

"Their research points to how cultural legacies can distort our perceptions of natural phenomena, even those that we encounter with our own eyes."

If we don't actually see all the branches but need cameras, the painters did paint what they were able to see with their "own eyes."

Also what the first photographer wanted to disprove wasn't the number of branches:

All matrix transforms are linear. And few people understand matrix transforms. The term itself "linear" transform stems more from the contrast to nonlinear equations, but it still "feels" like a bit of a misnomer. Perhaps it should be called "proportional" or "relatable" transform.

Ehh, then again, it doesn't really matter, people who don't understand it still won't with a nomenclature change.

One of the example Rails applications they use is the code which powers the OpenStreetMap website.

They populated their install by randomly filling in fields on the website. Which doesn't include any map editing! For OSM they suggest changing how the diary feature operates, which is a tiny, almost irrelevant part of the OSM website software stack. The OSM database has millions of geographic objects, and they talk about the diary system on the website.

> For example, when we profile the latest version of Openstreetmap, a collaborative editable map system, we find that a lot of time is spent on generating a location_name
string for every diary based on the diary’s longitude, latitude, and language properties stored in the diary_entry table

No. VP8 and VP9 bitstreams are frozen and stayed frozen when they decided to freeze it (they made that sure with automatic tests in libvpx that calculated the bitstream checksum) otherwise old VP8/VP9 files would stop playing. The difference is only with the approach as with VP8 and VP9 the "reference" decoder is the specification, which is not what many people like for various reasons (for example there were some errors in the implementation, which needed to be implemented by everyone because of that).

The first link you posted about VP8 just writes that they'll create an experimental branch (back in 2010) where incompatible bitstream changes can go in. Guess what eventually happened with those changes? VP9

The second link is the link to the unfinished VP9 specification, however with VP9 they still had that "reference" decoder code is the specification approach. As VP9 started to gain traction, the demand for the specification became greater, so they post-hoc started writing one but as you can see, they never finished it. Still this doesn't mean the bitstream isn't frozen.
It's a shame you got downvoted. I agree with you. I too have mixed feelings about the implicit normalisation and glorification of such an activity through profit-led media projects. Most curiously it's not just the media community that feel it's ok, but even the general opinion in the climbing community seems to accept it. Whereas I feel it sends deeply problematic mixed messages. On the one hand as a climber it's drummed into you to make safety the first and foremost concern. Yet here we see the romanticisation of an endeavor fundamentally dependent on the absence of life-saving safety. It makes no sense to me other than the simplistic gimmick of morbid curiosity.

I cannot believe for a moment that Alex Honnold doesn't get something from the attention he receives. There's something almost akin to the social taboo of watching others have sex, such as in pornography. We're not so much watching an athlete, but a psychologically notable person that allows us to vicariously experience the intimacy of emotions that arise from handing over one's very existence to the precipice.

A perfect time to whip out the sad story of one of my dwarves. Important to note that NONE of the details in this story are embellished, they are all simulated in-game:

I needed to tap a source of water to create a nice waterfall in my dining room. Everything was prepared: the waterfall would fall through the dining room, and then a channel under the dining room led off the side of the map through a fortification. All I needed to do was open the wall of the tunnel which was touching my water source.

Feeling too lazy to channel in from above (and slightly evil), I decided to go ahead and sacrifice a dwarf for the effort. I had the dwarf wall itself in and then open the wall. Two seconds later multiple bad things were revealed about this decision:

The dwarf was a mother carrying around her small child.

The water was under high pressure.

I had forgotten to make a floodgate to stop the water if needed.

The water shot out of the wall, instantly killing the baby and smashing the mom against the wall of the tunnel. She was dragged along by the water, fell down the waterfall and was pushed up against the fortification on the edge of the level with two broken legs and a bruised spleen. The baby's corpse was caught under the waterfall right underneath the dining room and wasn't going anywhere. The mother kept trying to run upstream but was unable to.

I felt pretty bad at this point. But thinking there was not much I would be able to do since the mother would certainly die soon anyways, I just tried to quiet my bad conscience and focus on other things, awaiting the inevitable message the mother had died.

A day later the baby's corpse started to fill my dining room up with miasma, making me have to wall out the waterfall to keep my dwarves from vomiting. Quite poetic justice, really: the stench of death was on my waterfall.

I was still waiting for the message that the mom had died.
It didn't come.

After a week of game time or so I looked to see what she was doing and my jaw hit the floor. She was FISHING. The mom was fishing to stay alive while drinking the water. She was in an obviously really bad mood having witnessed death and the decomposition of her child. But she was barely staying sane because she was being "comforted by a lovely waterfall".
That did it for me. I finally decided to launch a rescue mission to save her. Not 2 seconds after I had given the command to dig a tunnel to where she was, she went insane and died of thirst shortly after. I was too late.

Her name was Môsom.
Making bad decisions based on faulty understanding does not make you irrational, it just means that you don't know enough to make the optimal decision.

The really "irrational" decisions, such as decisions based on altruism, can still be made even with complete knowledge and understanding of the full complexity of the issues that led to the decision.
Look up maximum likelihood estimation [0] and look up newton's method[1]. Take the log likelihood of your data and find the parameters which maximize it. If that doesn't make sense, read up on numerical optimization.

@jasode's reply in this thread made a good summary of the two parallel discussions/quid pro quo:

- on filesystem vs sqlite (put git files in sqlite): there's a good benchmark on https://www.sqlite.org/fasterthanfs.html claiming sqlite is up to 35% faster than fs. I'd like to see the same benchmark with git's file pattern; also, it's a known issue with git that it was written for linux first, hence optimized against Linux (relatively) good fs performance (vs Windows and Mac at the time). Same with most OSS build systems that (over)use process forking, which is also very optimized in Linux.

- on Fossil vs git (why bother putting git files in sqlite and not directly jump to fossil?): that was my comment, and it relates to subject of this article (the commit-graph). I'm wondering if Fossil has seen the optimization that git has, with regards to number of commits, considering that sqlite is the only high-profile project that uses it. Maybe performance is supposed to be taken care of by the sqlite database itself ?

Edit: see https://www.fossil-scm.org/xfer/doc/trunk/www/stats.wiki for a fossil-provided performance analysis, that does a comparison with CVS (!).

I'd share my perspective...

old cities were the best.

i visited some european cities and some middle eastern cities.

there are main roads where traffic is, and then there are streets.

Streets are NOT made of cement, softer the material the easier to walk on ... Dirt? the best.

Streets can sprawl 4 blocks in US city size.

Streets don't have any traffic, but cars can be parked here and there randomly. (car ownership is less)

What it did was that grocery, laundry, hardware store, restaurants, and pretty much everything was in walking distance... you didn't need a car. and there were no cars to get in your way.

But with 5 minutes of walking you could easily be next to highway and hail a taxi.

All that time I was there, I was like OOOMG this make soooo much sense, I dont need to drive 4 miles to some mega shopping mall to do shopping then come back find parking for 30 minutes.

Oh and nobody was fat. Since everyone did light walking daily. people were less stressed as there was culture and less stress.

I don't get why every street needs to have a freaking car in it.
