I recently bought an oral-b toothbrush with the AI app thing, and it’s worked really well. Something about making the little dots disappear mean I’m now cleaning my teeth properly for 2m30s. Wish I’d had it a lot earlier and maybe I wouldn’t have so many fillings. (I swear this isn’t an ad, I bought it on prime day thinking I’d probably return it).

Also I doubt it’s AI, just doing something fairly basic with the accelerometer data

Looks like they've weakened the requirements by only requiring it for apps that add the dependency after May 1.

Why don't you just scan the alcohol last then?

Because you still need to wait for the attendant to come. But you have no chance of scanning other items in parallel. (Assuming you don't know if this store will block scanning)

It is always optimal to scan these first. You have two cases:

Blocking: scan 1 + wait for attendant + scan rest

Non-blocking: scan 1 + max(wait for attendant, scan rest)

However if you scan these items last the wait is always the same:

scan rest + scan 1 + wait for attendant

This is never shorter than either of the previous two. It is equivalent to the blocking case and almost always longer than the non-blocking case.

I agree it's a beautifully crafted response, and have nothing to add, it's exactly what my point was.

It’s questions like these that made StackExchange worth visiting and browsing. When they decided to be super strict about being on topic it made the quality of the sites go downhill a lot. Now there is much less reason for experts to hang out on the sites and while there provide answers to new questions.

I'll note though that it is locked. Anytime I find something super interesting in a SE forum, it has been declared off-topic.

When the transition started the first LED bulbs were awful. They have come a long way since then.

Ok but in the UK (and Europe im guessing) we had the ban on the old bulbs ages ago and yeah it was weird at first and the early LED bulbs were awful blueish white. But the bulbs are the correct color, the packaging has what tint the bulb is. Some people have smart bulbs that can change color completely and dim from apps and voice assistants.

The idea that the old bulbs shouldn’t be banned is ridiculous. You only have to look at other countries than the US to see yes it can be done and yes the world doesn’t end.

I'm not a fan of the dome shaped LED bulbs like the one in the picture, maybe i just tried the wrong colour temperature, or it is something about how the light is distributed.

Luckily there are LED fillament bulbs that are awfully similar to the old incandesant bulbs, except they last far, far longer and have the same energy savings as standard LED bulbs.

I buy those now.

Says it's a perfectly functioning phone and then lists how it's not because it's old and got worn out. apps requiring later versions is an issue but the % of people on old iOS versions is really quite small. It makes no sense to waste development time on implementing something for <1% of customers on iOS 14, when you could use a newer API in one line of code.

It’s not just apps requiring later versions, it’s apps using more and more memory due to the use of ever-more bloated frameworks and the like.

The vast majority of these apps would’ve run fine on a computer from the 1980’s running at a handful of MHz in mere kilobytes of RAM, if they were optimized. But they use the trendiest frameworks and require gigabytes of RAM and gigahertz of clock cycles to run their todo-list (or whatever it is they do).

Apps don't support older OS versions -> Nobody uses old OS -> No point supporting old OS as nobody uses those -> Apps don't support older OS versions -> ...

They don't have to be sentient. It doesn't need to be better at creating software than humans. It needs to be cheap and good enough. Most apps and websites are pretty similar, eg, blogs, storefronts. We have whitelabel apps and websites already, they're about to become a lot more customisable by a lot more people.

It's the same as IKEA, it's not as good quality as a handcrafted table from the 1800s. But it works well for most situations and most people.

The OP was describing their work on network code, not whitelabel websites. The work of making whitelabel websites was already hollowed out by firms in cheap markets (India, SE Asia).

A calculator didn't make mathematicians obsolete. It aided in the creation of more complex mathematicians.

Sure but it did make calculators and computers obsolete.

My mom was a computer in a bank. That was the name of her job.

Does your mom lament the fact that she is no longer a computer? Has she been jobless since?

Society evolves just at the available jobs do, due to technology.

I can't see how this is correct. The spinning dancer works because there's no details on it.

I was skeptical as well but after looking into it further I can confirm that it's actually true. The brain is amazing!

I still don't buy it - looking at these two in isolation:

Very "clearly" spinning in opposite directions.

The ambiguous effect of the silhouette dancer is real, but some of the sandwiches really are rotating in a different direction from the others.

When I realised that branches were just labels pointing to a commit, instead of a an actual "branch" ie a group of commits, then everything made a lot more sense. I still kinda wish branches were more groups of commits, so that if you have multiple branches on top of each other they can automatically/more easily keep up to date.
