Well, it has taken years but seems like Boston Dynamics and similar companies have moderately agile walking robots. Yet somehow these don't seem to be appearing anywhere.

Now we hear there's progress in gripping.

The thing about both these steps is walking and grasping are extremely challenging tasks to robots but even more challenging is the easy integration of these and other movements that humans achieve when doing "simple tasks" and especially cooperating in simple tasks - in the "unstructured environments" referenced in the article.

If you told this out loud during the 80's and early 90's everyone would just laugh.
Unnecessary movements. If you put rollers in the cart itself, docking the cart at the POST and spinning a torque rod with a tri-lobed docking coupler--like on those old Capsela toys--could move everything on the cart within reach of the cashier.

Ideally, the only movements the customer would make would be to place items into their cart, and move their entire order, already packaged for transport, into their vehicle at once. Unloading from the vehicle and moving to a pantry or refrigerated storage should also be easy and free of unnecessary movements.

My solution would be to make the carts a platform of elevated rollers, carrying several reusable bins, owned by the customer, and manufactured to an open standard. While shopping, the rollers are locked, and the bins are secured in place. The customer can choose to organize foods in bins according to their individual needs. Put all the dairy in one bin, and meats in another. Put canned and boxed goods in one, refrigerated and frozen into another (insulated, perhaps).

At the checkout, the platform docks. The cashier scans from the nearest bin into a sorting area, and a second employee, the customer, or the cashier can re-pack the bin in a sensible way, rather than according to the disorganized arrangement determined by the layout of aisles in the store. The packed-for-transport bin moves onto a second docked platform. The docking station spins its torque rod to move all the rollers, and the remaining bins move closer to the cashier. Process repeats until all bins are scanned and packed.

Customer pays, and rolls cart to their vehicle. They put the lids back on the bins (which are now stackable closed containers) and stow them. The roller platforms stay in the parking lot. When the next customer arrives, they load one up with empty, lidless bins, and enter the store, ready to shop. New bins sold inside the store, likely at a wafer-thin markup.

At home, the customer might have their own handtruck to move bins from vehicle to food storage. Maybe their pantry has roller shelves, and a special drill bit so a handheld drill can spin them. Or maybe they just have regular shelves, and stick PTFE pads onto the bottoms of their bins for easy sliding. Perhaps they unload the bins and stack the empties for the next shopping trip. Maybe they can plug some hoses from a cooling unit into an insulated bin to turn it into a miniature refrigerator. As long as the bin conforms to the external dimensions and weight standards, it can have any number of additional features included. Pelican, Coleman, Igloo, Yeti, Rubbermaid, etc. could compete on those special features, or on materials.
> As someone who went to a "lower-tier" school. I hate how true this feels sometimes.

So much so that I often feel like I would have been better off never having gone to college in the first place than having gone somewhere not in the top 50 (or even in the top 10). Presenting yourself with no degree at all as a "tenacious, self-taught fighter" feels better than "I went to the University of Bubba because MIT said you're not smart enough" (plus MIT is really far from where I grew up and really expensive). On the other hand, I've worked with plenty of really smart programmers who don't have a degree who've felt that not having one has held them back - although I've always wondered why they don't just go back and get one.
It's really cool to see present-day artifacts as someone 400 years from now might see them. "Flippo disk." "Mobile telephone."

How so? Both Lime scooters and electric bikes are supposed to be ridden in bike lanes on the road, although enforcement can be hit-or-miss.

Those three words seem to be doing a lot of work. How would you minimize systemic effects? What systemic effects even need to be minimized?
>Being able to conjure up a confession for anything by anyone is extremely powerful

Being able to dismiss credible video evidence as 'deepfake' is equally powerful.

In any case, it would be extremely risky to hang a case on a single confession video that the accused claims is fake, given the current pattern of prosecution the DOJ would never bring that case; it would be embarrassing in the public eye and probably overturned on appeal, if it even made it to trial.
Sorry for my late reply, I just wanted to thank you because your comment is an exceptionally good example of what I was trying to get at with my longwinded explanations. Compiling MIMD to SIMD is the future of programming, although it seems that companies will try every other course of action before they realize that.

Except you do some places. In San Francisco it is illegal to ride an e-scooter on the sidewalk. You are supposed to ride in the bicycle lanes.
FWIW, it was also extremely restricted when I used it in Toronto. Coverage only went as far as middle of Korean Town, meaning you couldn't use it to go to, say, High Park. For commuting it was an even sillier proposition, because the coverage overlapped with the densest subway/bus grid in the city, and it was not much cheaper per month than a subway pass, unless you got a groupon for it.
Since this is oddly getting down votes for some reason, I'll quote wikipedia[0]:

I assume you're joking, but yes. The issue is surface area and cross section, as these very small molecules tend to disrupt/block catalytic processes inside the cell. In the early hype days of nanotechnology they were thought to be extremely bio-compatible because they are basically chemically inert from a biological perspective, but it turns out they can act very well as a wrench in the gears of cellular machinery in ways that we are just now beginning to understand.

I don't want that to be considered anti-nanotech in any way, as that is my field and hope for the future. But that vision of carbon nanobots swimming our bloodstream is probably not accurate foretelling of the future. We'll probably be using protein components instead for easier bio-biodegradability.
> This especially matters when you start doing dumb things to codebases like 1-space indents

Too-small indents are bad for many of the same reasons as too-long lines, only even more so. The main argument in favor seems to be the desire to cram as much as possible into each line, which is a code smell of the first order. The main argument against (which I find much more compelling) is that it becomes really hard to match up the indentation levels to see the true structure of code without artificial aids. Besides being ugly, those faint vertical lines won't be there in every situation, such as when you're looking at code in a review tool or in gdb or a "primitive" editor while you scramble to fix a problem on a production machine that doesn't (and shouldn't) have your favorite heavyweight IDE installed. Ergonomics matters, and it's about more than personal preference.

The innovation here is that this PR person works in the Rail Control Center, with the people who are actually running the subway. Not in some PR office. She's surrounded by the people who are telling the trains what to do, controlling signals and switches, and dealing with problems. She can see the track boards and listen to the comm loops.

Contrast this with big sites which have status pages showing everything is just great half an hour after it's hit the mainstream media that they're down.

It's very New York. When Maersk Shipping had a big hacking incident and was down for most of a week, the best no-bullshit info was coming from someone at the Port Authority who edits their feed for truckers. Maersk PR was saying "almost everything is fine". The Port Authority trucker feed was saying stuff like "Maersk can't take outbounds at APM, only one gate is open for inbounds, don't return empties at this time". That brutal honesty beats horsing a semi over there to find out you can't unload.

Strict being the opposite of lazy - expressions are executed immediately.

Like for instance, given an expression...

x = foo(13)

In a strict language foo(13) will be evaluated immediately.

In a lazy evaluation model, x be 'the result of foo(13)', but foo(13) won't actually be evaluated until some expression forces evaluation, by, for instance, printing the value.

This is a gross simplication... lazy can do some really neat things like having functions that return infinite streams. The function would theoretically never terminate, but in practice would be called via something like...

for event in infinite_stream()
.. do stuff ..
if event == TERMINAL_VALUE:
break

While it may be simpler, it may also be inaccurate. The fact that Intel's dominance isn't as pervasive as before does not mean it's no longer #1. AMD has a long way to go.

One a related note, to my knowledge AMD is still essentially absent from the Autonomous Driving market, with NVIDIA and Intel fighting to be top dogs through different approaches¹. With some estimates for the size of that market (including non-chip portions) going as high as trillions of dollars², I hope for AMD's sake it has a plan to catch up sooner rather than later.

Having the right subject matter makes a difference. Baseball has a ton of data that they collect about each game. I wanted to learn R and took an online class where the professor was a Sabermetrics guru. Made the learning of R fun while also learning more about "inside baseball". I turned that into a small AI project on what players would be / should be traded as the season came to an end. (Teams that are out of the running will trade top players away to teams that are in the running to win their divisions. ) It was fun, because the subject is interesting.

Trying to teach programming with a dry subject matter is very hard to do (Calculate area under a curve for your second programming assignment anyone?)

Congrats on the son keeping up with it
For me, it breaks down to:

The prevalence of law enforcement in schools in recent decades is a troubling practice. Pranks, misbehavior and disruptions that were once handled in school with detention or other discipline are now referred to law enforcement where the system is absolutely not designed to teach or rehabilitate, but rather to punish.

I remember students getting into fights and being sent to detention or in-school suspension together and afterwards things being fine, now schools are calling the police and students are being put in jail, sometimes never to return to school.

But there is the opposite where this technology can be used to falsify a video that can potentially be used to make false confessions or change what a person said for nefarious purposes.

One angle that is missing to this story: Nokia. Nokia bet big on Intel by partnering with them at the worst possible moment. In a nutshell, Intel was looking to get in on the mobile action and Nokia was willing to partner. This was ten years ago.

When platforms failed to come together because Intel was not delivering the goods, Nokia had to scramble to get new phones ramped up around alternative platforms. Nokia lost a lot of valuable time this way right when Apple and Android started kicking its ass. I wouldn't point at it as the root cause for Nokia's rapid collapse but it certainly was a contributing factor. E.g. Meego was years late to the market partly because of this and ultimately killed off in favor of the deal with Microsoft (another ill fated bet). And yes, Intel Atom was a big part of that failing as well.

Bottom line is that Intel tried and failed to get into the mobile market repeatedly and failed while being way too comfortable milking desktops and servers. Now that that market finally seems to be drying up, they have a problem and still no viable strategy to deal with it. Atom flopped. Itanium flopped. AMD is back looking stronger than ever. MS is has retired the wintel brand years ago and is seemingly open to running on ARM and getting quite cozy with Linux. Apple is widely rumored to also consider switching to their quite credible in house ARM based processors.
Ok, I know we like to dump on Americans with impunity, and I'm not even going to get into whether it's deserved or not, but have you driven in much of the rest of the world?
This is a satirical piece, and I don't know how that was missed. Of course, if I'm wrong, and the author wrote this to be taken literally, then this is a poor manifesto to follow. It seems clear the author was trying to point out how backwards it is to argue against using popular, supported, and progressive technologies. I'm going to inquire if it was in fact satire, but it seems like it to me.

Semiconductors are a scale business. The one with most scale wins. The margins are of less relevance.

Intel has always been the unbeaten one, with most chips out there by an order of magnitude. Now that they lost this lead, everything (including P&D and margins) is expected to suffer.

I'll add a concrete example. My dad worked for a TV station. Of the 5 VHF stations in town, one was public TV, three were network, and one was independent.

One of the other stations was union. My dad's company was not. The owner of his company did not want the union. The owner kept the union out by paying everyone $1 more than their counterparts in the union station.

My dad thought this was great. He got the benefits of the union - higher wages - without paying union dues.

I look at it and think about how Dad could have gotten higher wages by being represented by a stronger union. Union power, like most things, is non-linear. A bigger union can pay for better negotiators than a small union can. That's a simple economy of scale - a larger union can have dedicated, full-time lawyers, for example, who stay on top of the laws and potential changes to the law.

When the owner died, and the station got bought out by a private equity firm, the firm did the usual round of layoffs, and it sold off the company into parts. A union might have been able to fight some of those layoffs. But there was no union.

But when he boasted about how he made more because he was non-union, such alternatives and futures were out-of-sight/out-of-mind. As you say, "Humans are short-term thinkers".
