My opinion on WiFi is that as long as the end user(s) have a decent router/access points (AP), it's great. If the end user has a crappy $25 router or are trying to cover a ridiculously large area with a single AP with a very sub-optimally placed AP (e.g. think bottom of a closet), then yeah they're gonna suffer. Almost no one needs a $200 prosumer router nor a Ubiquiti setup, but everyone needs something better than a $25 router. My experience is that the sweet spot is around $70.

Bluetooth is definitely a disaster though. Apple has made great strides with their AirPods and the (It Just Works)™ philosophy behind their products, but even the AirPods aren't perfect. Once every month or so, my AirPods just refuse to connect for whatever reason and I have to restart the device outputting sound to get the connection working again.
The best part is that the headset can be connected with a wire to both Xbox and PS4 controllers.

Also the custom dongle has an 3.5mm output plug for speakers, which will automatically turn off when you switch on your headset.

Gmail's handling of tracking pixels might be even better, it automatically downloads and caches all images in a email. This has a few benefits: 1) Renders any gmail "open rate" analytics useless 2) Makes the email load faster in your email client since images are coming from Google's fast cache

Q1: Who's going to pay for it? Any idea how much of an effort it is to create a video game that teaches, let's say, statistics? Or geology? Or history? It's a bit more than writing a text book or creating a series of video lectures.

Q2: Who's going to check the assignments? That'll be people, because there's no system in the world that can correctly do anything else but check multiple choice tests and/or provide sensible feedback. We've been trying that for 40 years now, and the results are not hopeful. But if you've got people checking the answers and giving you feedback, you're not reducing the costs by much.

And about that KSP remark: while physics is one of the few areas for which you can build decent simulations, that game won't teach you the basics of combustion, control systems or material science. It just lets you play around. That's fine, but it's no replacement for a PhD.
I made a pinhole camera that plots 3D geometries in matplotlib/geopandas[1].

It's still WIP (need to do some minimal ray-casting to deal with depth ambiguity), but the overall goal is to develop a set of minimal camera perspective matrices that can be easily be extended for other uses (i.e I want to use my cameras to calculate geometric view factors as a way of clustering geometric features for statistical learning). Another application I've tested is to use camera and location parameters from the Google Street View camera to project OSM footprint geometries onto street view images.

Not an application, but this my favorite explanation of SVD:

It's such an important operation that I'd say understanding it changes how you understand a lot of linear algebra. That Kun post is also good.

> If your statue doesn’t unequivocally reflect only one good message to all people, you’ve got a problem.

By this logic, we should tear down all statues, since it is impossible for a statue to "unequivocally reflect only one good message to all people".
Maybe my point wasn't clear, but {{{ and {{ look too similar. It should be {{ and something else. Like {{Dangerous=username}}.

You shouldn't have to squint at your templating code to see if there's an XSS vector or not, or defensively/neurotically grep for "{{{" just in case you didn't trust your team to squint sufficiently.

For comparison, here's JSX: <div dangerouslySetInnerHTML={{__html: username}} />.

vs. Mustache: {{{username}}} in a file of 1000 other { and } glyphs.

Mustache's hey-dey is long over thankfully.

Collaborative writing can be great fun - I used to contribute (on occasion) to collaborations on Usenet poetry groups (when taking a break from tweaking the trolls). I wish you all the best for taking this project forward!
This is just so hard to read. I can't concentrate on what the author is trying to say because I'm constantly distracted by the way they're trying to say it, meaning all the irrelevant exclamations with which the author is peppering their tweets.

I have to wonder: what is gained by mixing up so much noise with an interesting message? Isn't there enough useful information in the subject of saccades, without the tone (which I suppose appeals to some)?

It's like when you're trying to hold a conversation with someone that disagrees with you on the internets and they constantly try to troll you, starting their comments with sentences like "no, this is wrong, you're an idiot and you don't know what you're talking about" before telling you why they disagree, or what they mean etc.
OMG. Their original plan was bat-shit insane and it went downhill from there.

ADDED: I think Google Maps has gotten better at simply not offering really questionable routes as an option. At least that seemed to be the case when I played around with it the last time I read the German tourist story. I think you can force it if there is no alternative to get to a specific location but it tries hard to avoid the very iffy routes.

And once they did get stuck, they behaved sensibly which--perhaps along with a bit of luck--got them out of things.

Indeed -- studies of SARS have something different to say. Here's one study that shows duration of antibody response to SARS is at least 3 years [1]. Here's a study that shows T cell response for at least 6 years [2].

MERS had a much, much higher fatality rate (~35%) and infected a small handful of people (~2500) so it's harder to get meaningful data.

Let's see; a one semester class is 3 hours/week, 15 weeks, or 45 hours of lectures. The semi-official ratio was to expect 2-3 hours of work in addition to the lectures (haha, yeah, I slacked off a lot), so that would be 135-180 hours. The books chosen sound appropriate. Sounds about right to me.

Sure, but that does not strictly explain the phenomenon.

The headphones have clear line-of-sight to the laptop in both the "off" (comfortable) position and the "on" (infinite set of uncomfortable) positions.

The absorption of the radio signals by my large capacitance, I would think, doesn't change much with position. Also, it turns off when I scratch the back of my head.
I don't think it's exactly racism in many of these cases, so much as a lack of empathy. If you're not personally affected by these terms, and you're not able to empathize with those that are, I can see why, without being overtly racist against any particular group of people, you could be against these changes.

Our inability to empathize, or "put ourselves in someone else's shoes" is at the root of so many of our problems...

Educational video games have been around for like 40 years now, I don't see what would have changed to suddenly make them better.
This is the introduction to a topic, and starts by asserting we are already tired of reading the title because we have heard it so much.

Five years ago this would have been blog post one of four.
Journaling or therapy can be effective strategies. Both give you the outside perspective needed to spot patterns.
This line again... Education only works insofar as it acculturates children to greater society (or novices to the society of some specific domain). The methods of education are social, present in the surrounding culture and mediated by teachers through social interactions. Consequently, for video games to be "the future of education", video games have to be the future of society as such. Video games are _in_ society, much like music, television and harry potter, but neither are "the future of education". Not even the printing press could upend the basic structure and process of education, only add literacy to the curriculum. Forgive me, but I just don't see "playing video games" make that list in any meaningful way.
How will the bot answer "when and where were you born, and how do you know?" How will it answer "what color, besides red, best communicates the flavor of a strawberry, and why?". How will it answer "What historical figure does my communication style make you think of most, and why?", or "Which of your family members comes to your mind first?" or "What do you think the context was in which the following poem was written?". I don't need to know what it was trained on to win this bet, and 20 open-ended questions is more than enough.

Between the vast majority of unsuspecting humans and me there is a considerable gap. Mind the gap!

I trialed a 2GB memory, dual-core-no-hyperthreading low-clocked Celeron ("hacked") Asus Chromebox as a workstation a couple weeks ago. As long as you can avoid running electron or other webshit and don't mind doing some things on the command line it could handle light tiling window managers (i3, dwm, awesome) just fine, even at 4K. Actually the Web was even pretty OK as long as I only had a couple pages open at a time and used Surf (just trying to open Firefox took so long I gave up—Surf is almost instant) If you've got a remote machine for you VMs or Docker and maybe for some remote X sessions for heavier web browsing, it's viable. Really as long as I avoided web garbage and used light software the thing felt fast. Very responsive, low input latency. Hell it even booted much faster than the beast of a machine I replaced it with (that's Void Linux's doing, by having a minimal default boot environment so the boot process isn't doing very much that I haven't explicitly told it to do, so no useless-to-me daemons or scripts slow the boot).

Which shouldn't really be that surprising since my primary development and gaming desktop at one time was a fraction as powerful and did GUI multitasking just fine (including Firefox—I maintain they really lost their way as the lightweight-but-still-featureful browser we all loved after the 1.x series and have never been as good since), but, it is surprising these days when we have single browser tabs that can just about fill 2GB of RAM all on their own and forget what modern computers can do when we're not using them to run the computing equivalents of 3-legged-races.

Only reasons I didn't upgrade the RAM and keep going with the experiment were 1) it could only drive my 60hz 4K display at 30hz, and 2) manually dicking around trying to fix 4K scaling issues isn't my idea of a good time and you pretty much have to run a heavy desktop on Linux to eliminate those problems without tons of fiddling, it seems, and such a machine cannot handle Gnome3 or KDE and all their background crap and Javascript (ew) and such.

That's not to get educated, that's to drill for exams. I mean sure we call it education, but it's not, it's for making hamsters who will make powerpoint slides when they're older.

Real education, understanding the beauty of nature and mathematics, you need to teach yourself. Sometimes you will find inspiration in school, but mostly you are learning how good attitudes like keeping organised and doing your preparation.

It's because for lots of people 'perceived maximum' isn't fixed.

Imagine you just lost an auction. I come up to you and say "Would you pay $5 more than your max bid if I guaranteed you'd win?" If you believe anyone would ever say 'yes' to the above then you agree the auction sniping service has utility.

This isn't a question of finding a magical solution, it's a question of trade-offs in performance, complexity, and usability that any solution necessarily imposes, and whether those trade-offs are worth it to support a feature that 99% of use cases don't need.

"Skyscrapers have been solved since the 20's" doesn't answer whether I should use steel beams when building a house.
I think something that is being lost here, is the fact that video games are a broad term and educational video games are nothing new, in-fact, they've been around at least since the 80s.

To me, this isn't about producing educational video games, as much as adding video game elements to existing products and making something new and compelling to the consumers.

An example of this would be Duolingo (https://www.duolingo.com/), it's not a game, but it acts like one by introducing mechanics from games into it's identity such as the concept of leveling up, completing levels, earning points... They also do this on a visual level that feels mostly gratifying for it's users.

Of course educational games also have a place, but they're mostly disdained by children
My point about 10x developers is that they're not 10x better than average per the stereotype, but avoiding 90% of the wasted effort the average dev expends.

I'm lurking over currently sold low-spec laptops from Lenovo, Dell and HP, and I'm completely baffled these brands aren't even trying, even though the cheapest models end up ~2 times more expensive than those Chinese OEM machines.

I just want a sub 2kg machine in [11-14)'' range with FHD, CPU at least on par with Ryzen 2200g (which is not quite the newest model) and slotted RAM for under $400. All I see is 15" models with poor TFT displays and RAM sizes that would be a downgrade from my 10 year old Acer!
Automation is something teachers could really use. There is a morass of manual labor intensive tasks which are currently required for lesson prep, for instance.

Autocitation with Autofill. You write what you remember of the source material you wish to cite, highlight it, and the editor finds the source, corrects any errors and missing bits, then adds it to the properly formatted numbered index.

I'm guessing you are looking for code-related features, but there are also documentation and technical papers to worry about.

Manipulating America: The Chinese Communist Playbook – China in Focus
> I can’t imagine anyone dealing with kids learning from home this lockdown and thinking education should be more technologically driven.

With the possible exception of the social aspects, lockdown distance learning seems like a waste of time vs. self-directed learning. Which could be as simple as letting kids do things outside and around the house. Or maybe providing bookmobiles and mobile libraries, maybe even a small budget to allow each kid to buy some affordable paperback books from an educational publisher like Scholastic, or cheap used books.

Perhaps schools could focus on providing resources and support for whatever students might actually want to learn (perhaps from a broad list of options) at their own pace, rather than forcing a particular curriculum at a pace dictated by the school.

Technology-wise I am not sure that the current lockdown remote classes are more beneficial than, say, playing video games (or other games) for a couple of hours a day, which would also probably be more fun and social (though single player games are also fine) and more enjoyable for parents as well (especially if they get to play a bit too.)

> Although generally described as highly predatory and primarily feeding on fish, piranha diets vary extensively, leading to their classification as omnivorous. In addition to fish (occasionally even their own species), documented food items for piranhas include other vertebrates (mammals, birds, reptiles), invertebrates (insects, crustaceans), fruits, seeds, leaves and detritus. The diet often shifts with age and size.

DOTT is particularly special for being a sequel to Maniac Mansion, a Gilbert game I had briefly played somewhere on the original NES.

The entire Maniac Mansion game is also included in playable form within DOTT, on a virtual computer found within the game's environment.

I remember first playing DOTT on the PC and discovering the embedded Maniac Mansion. Up until that point I hadn't realized I was playing a sequel to that NES game I'd long forgotten about.

They're fun games, quirky with a great sense of humor and playful innocence about them.
Piranhas are scavengers.

The typical diet of red-bellied piranhas includes insects, worms, crustaceans, and fish.[13] In packs up to hundreds, piranhas have been known to feed on animals as large as egrets or capybara. Despite the piranha's reputation as a dangerous carnivore, it is actually primarily a scavenger and forager, and will mainly eat plants and insects during the rainy season when food is abundant. ~ Wikipedia.
