Note that the video claims it's 5000 Li+ batteries. It's hard to tell from the video, but it looks like it was ~4 boxes filled with only the batteries. Even a large pile of laptops (no bags) would have a hard time making the explosion[1] in the video. If you separated each battery+laptop into separate bags, the density of Li is so low a single battery burning/exploding may not even reach the other batteries.

Job sites, especially those in the throes of major structural construction, are a horrible place if you are seeking consistent wifi or cellular coverage.

Generally: The thick concrete walls, exposed rebar, and intentional and unintentional geometric structural elements combine to form a giant Faraday-esque electromagnetic exclusion zone. Even with wifi repeaters on each floor you aren't assured a connection.

I worked for LATISTA as a product designer and spent a significant amount of time on-site speaking with users about this exact problem. It's getting better, especially with the larger construction management / development firms, but it's not a solved problem (unless your firm spends a significant amount on portable IT infrastructure).

This is in itself not scary compared to what a random website does when I visit.
That is - given that what we see in this log is actually all it does. What's scary is what we don't see (does it store this? does it cross reference anything? does it target ads based on it)?

I don't really think that's the case (here, yet) but I do think it's scary that it's so easy to do that its not just done as a proof of concept but actually used in production in a low tech industry.

Gathering demographic or sentiment without storing, cross referencing (has this person been here before etc) or otherwise using the data for anything such as targeting ads - is kind of acceptable. I mean it wouldn't be hard to do that manually via a camera if you wanted to test the engagement of an ad. I'm sort of hoping this is just some tech project from a university or something, and not an actual product you can buy and hook into some adtech service.

Edit: as someone else pointed out - it's not a proof of concept it's an adtech off the shelf product. Because of course :(

The EU and its member countries are still interested in personal privacy. Do they regulate insurance providers? Could EU, or Italy, exact a penalty against this provider for failing to do the most elementary of penetration tests on this system? Perhaps some of the penalty should be a return of premium payments to customers whose information was potentially exposed.

The point is to make the business-risk managers in other provider companies say to their executives: "We cannot take the risk of skipping cybersecurity hardening. If we do skip it and we get caught, our business will be forced into bankruptcy."
"There is no need for such thing as programming geniuses. There is only need for less clueless management and less opportunistic houseboys."

They did not learn rules of general programming but exceptions after exception in that one restricted system. When they were ready, that platform had died totally. But the government projects lumbered on for years. Only around 2014 last of the symbian courses was replaced with android.

Why would that be "unsurprising"? It's not like mental illness is intuitively correlated with increases/improvements in brain functioning...

If anything, one would expect the inverse: for some mental illness the increase in brain functioning around mid-twenties would somewhat help reduce it.

I'm sure it is an important factor in how the brain works, and that the research is insightful. I'm having some trouble with the idea of extrapolating complex behaviours from what essentially is a micro-benchmark of cognition. That sounds overly reductionist to me.

Although I guess it is impressive to find consistent results within said micro-benchmark, of course, since that hints at something fundamental about our biology (in the reddit AMA linked elsewhere in the comment the author claims to see no difference for gender, educational background, etc; suggesting age is the main factor. That seems significant).

This is also relevant for CSS: Some browsers (I think Safari) treat "transparent" as "transparent black" for gradiets, so "linear-gradient(transparent, white)" will result in unexpected grayish parts in the gradient. As a workaround, one needs to use "linear-gradient(rgba(255, 255, 255, 0), white)" instead.

Given that ajax was only added to browsers in 1999 and AJAX didn't really catch on seriously until 2003/2004ish, what you're claiming is at odds, again, with actual history.

404s are a different matter because you'd get 404 pages, so it's not at all an argument to support your position. It doesn't mean developers understood what to return from an ajax call, or that they understood HTTP verbs.

I'll remind you again that it was actually fairly hard to return the correct codes from a lot of frameworks, so objective facts are at odds with your recollection of events.

I stick by my assertion that the vast majority of web developers in our industry didn't really understand http until the latter half of the 2000s. I also specifically remember presentations to all our developers both junior and senior of how browser caching worked, which to most developers at the time was a bit of a mystery, and the correct headers to return to control it.

Here are some examples from 2008 of developers on SO discussing things which seem obvious today:

I agree. My main keyboard is a Microsoft Internet Keyboard that I have been using for many hours daily since 1999, surviving five different computers (all running Linux). It's the most comfortable keyboard I've ever used, and it shows no signs of wear other than having some stains, plus partial fading of a few of the key symbols, and the Ctrl and C keys are beginning to show dents where my nails have been hitting them.

Yes, it is. What is also really nuts is that insurance will cover cochlear implants. I mean it's cool that they do, but my friend explained it to me that the implants are a medical procedure and the hearing aids are classified as a "luxury item" or some such. The brutal and insulting part to the story is that he found this out because his daughter had cancer, and she lost her hearing due to the chemo therapy, which means that she was forced to lose her hearing due to medical procedures.

Given that today's airplanes need several km runway to take off and to land, and that people often need to transfer from one plane to another, we are probably not going to have many more airports per city than we already have in a foreseeable future.

But if an airport terminal could just be a series of small waiting rooms, one for each plane, sort of like today's gates but where where you met up directly at the gate with your luggage 30 min before. Then everything from passports to tickets, to body scan and luggage, was checked once, just once, and then you boarded the plane through at least two jet bridges (front and back on a normal plane). End of story. Those who wanted could show up an hour before, and they would get a small rebate and not have to wait in line, and those who wanted could show up 30 min before, and they would pay a little more and wait in line. And the plane should not wait for anyone who's not there 30 min before takeoff.

Could you board a standard narrowbody plane with 150-200 passengers in 30 minutes (if none of them opted for early boarding)? Two jet bridges, each with at least 2 security lines with scans/pad downs of passengers, a couple of luggage dumps with scans of luggage (I imagine it could largely be done automatically). A normal narrowbody plane with 150-200 seats means each line should handle 75-100 passengers in 30 minutes. That's around 3 passengers per minute or 20 sec per passenger. Should be possible. But I think many would opt to meet up shortly before and save a bit of money.

Same in the other end. You would pick up luggage directly at the plane, and have your passport checked immediately as you enter the terminal.

Much of the waiting in airports is because airports want passengers to mix up in the shopping mall before check-in and takeoff.
That's what I want to hear :-). Thanks for insight.
Good work with the README, actually explains exactly what the project is, with a very clear outline and screenshots.

Well done.
Personally I like more the idea of C# native or Kotlin Native than Go (too simple) or Scala (too complex).

Regarding CoreRT, I think it's still work in progress. However, you could just use the regular dotnet core for now, you'll just deliver a zip initially. Then as soon as CoreRT is ready (which should happen this year) you can just switch to that and deliver just an executable.

It's really hard to pick something at this stage since except for Go none of the alternatives are production-ready right now: CoreRT, Kotlin Native, Scala Native.

So it's more about which language/ecosystem you prefer and which one you see growing faster/more. CoreRT has Microsoft's backing, so things will definitely happen. Kotlin Native is backed by Jetbrains, so it should also advance. I'm not sure who's backing Scala Native, there must be a company paying the bills for the initial development.

While that's strictly true, there's a wider range of backwards compatibility they're keeping.

See the whole Rust/Cargo problem on Windows. Windows files can't be named con, aux, etc., because the Windows file systems are backwards compatible, generationally, all the way to DOS, which didn't have subfolders initially and which reserved those keywords for special files. Then as DOS added subfolders it still kept that global restriction, then Windows adopted it... and here we are today.

Windows is full of these things, a lot of them coming from DOS and more coming from Win16 or even early Win32.

I know they broke backwards compatibility in the strict sense with Win64, but apart from this not many situations where they did it come to mind. And even for that, they only did it because the overall market for DOS/Win16 was tiny at the point when they did it.
I see 2 separate issues here:

1. Accurate collection of facial features. Illumination, occlusions, head rotation, etc. may seriously affect accuracy, but this is exactly our main focus right now. We are at the very start of the process, yet early experiments and some recent papers show that it should be doable.

2. Correlation between real and detected emotional state. At the moment we concentrate on the 6 basic emotions and don't detect less common expressions like depression with smiling face. This topic is definitely interesting and I'm pretty much sure it's possible to implement given enough training data, but right now we try to concentrate on different things.
Not any more.

There are airports which have something like this, but generally it's very expensive to maintain so many separate security checkpoints.

In the US, the Kansas City airport was originally designed and built before any type of security checkpoints were present in airports, as a series of horseshoe-shaped terminals. Now, each terminal is internally divided into groups of a few departure gates each, and each one has its own security checkpoint. This is extremely convenient for people coming to the airport -- when I lived there, I could arrive 45 minutes prior to my flight, knowing I would get through security and be at the gate by 30 minutes before departure (which is when boarding begins). On the other hand, there are very few amenities beyond the checkpoints; toilets had to be installed, and there are a few counters selling food, but only one area that I know of has a real restaurant available inside.

And it will almost certainly be torn down and completely rebuilt with a centralized single security checkpoint, because operating it in the current setup is too expensive.
I would call this test an analogue of IQ testing. Again, we see how mainstream thought places IQ on a pedestal. Mainstream thinking overvalues and overrates mental gymnastics, such as performance on IQ testing. But learned experience is in my opinion far more valuable and should be valued more by mainstream thought. At age 60, it is true that I cannot perform as well on IQ tests. But in my opinion my understanding of the world is much greater. I was like a child at age 25, even though I tested well on IQ tests. But I was just a child. Does mainstream scholarship explore this facet of human development? Not much....
