A couple of years ago I wrote extensive benchmarks on three browser-based rendering techniques: text in the DOM, 2D canvas, and WebGL canvas.
The DOM approach is the purest, as it uses a font, and it can achieve very good performance. The only noticeable slowdown at 60 FPS occurs when the character color changes frequently within each line: each new character needs to be wrapped in a span. 2D canvas is a bit more flexible but not necessarily faster.
WebGL is obviously the fastest, at 1000+ FPS, and pixel fonts can be rendered ultra-crisp as well.
Below is the DOM test for frequent vertical color changes.
Press and hold the cursor over the ASCII output to change the orientation (notice the FPS drop at the top left).
I suspect DOM is probably fast enough for most usecases. For me, DOM only started chugging because every tile (2 half-width characters in hexwalker) was a react element and those would get garbage collected en-masse and cause studder.
It is rude and annoying in general. But even in quiet cars it seems like many people just don't give a fuck and will simply jabber on obnoxiously without any care for anyone else.
Would be nice if people could keep their noise levels down in general.
It's rude to me as well. But I think we are wrong about this.
I was in the doctor's office and a person was on the phone talking in the waiting room. I thought it was weird. But then I thought "if a person was sitting in the seat next to them and they were talking, would that be weird?"
I don't think we'd see two people talking as being weird. Why is it weird if someone is by themself speaking to someone that isn't around on the phone? If two people can speak in that place, it's not weird for someone to have a phone discussion.
Now playing music speakers or watching TikTok videos on your phone in a public place...psychotic!
That’s a good observation. I think it’s where their heads are facing. Two conversationalists face each other or face the room, but talk quietly with body language that suggests they’re conversing (heads tilted, leaning.)
Someone talking on the phone but facing away from the room isn’t usually considered rude, either.
In a waiting room or train car, if you’re sitting and talking on the phone or Zoom, you’re broadcasting into the room with your posture. Your voice tends to broadcast as well with no wall or other conversant as an immediate barrier.
I would consider two people talking to each other in a waiting room or on a train very rude too. If they are loud enough that the people next to them or behind them can hear the words they are saying, then it is rude of them. Of course, this is relative to how noisy the place is overall.
Unfortunately people all over are starting to not do anything.
On a recent plane ride some old guys were watching movies on their phones on full volume. I complained and they stopped, but another guy in another row started doing it again. It gets tiring.
Last week I was on a NYC subway train to JFK Airport and there was a guy blasting some loud hip-hop/trap and a small kid playing some loud game, totally oblivious to the people on the train. After they left some older guy stepped in talking on full speaker to someone for 10 minutes.
It was quite crazy tbh, and I guess people here have already given up and start accepting it since it is tiring to police somebody new every 5 minutes and could also end in violence.
I am in the give up department. Don't own a car, so public transport heavy. TikTok adicts everywhere, elderly taking video calls on super high volume, people playing or recording Whatsapp audios etc. has become the norm. Every bus, every restaurant, everywhere I go, people do it all the time. Pointing it out and confronting people has become pointless, it takes 3 minutes for the next person to offend. It is easier to accept it and hope for noise-cancellation technology to become better.
I found it easier to use anc headphones with white noise. I'm waiting for the next 5 years to pass, then I could also have my glasses that block all kinds of abominations from my vision, as it became normal to put cancer video ads everywhere in the public space. The future looks really good imho!
The number of people blasting video on a regional flight with no internet really made me reconsider just how necessary airplane mode is. Probably an applicable case study for many other societal boundary-breaches silently spreading.
I think it depends not just on culture but also on the volume of the conversation. Some people manage to have a conversation when you can barely hear them; others seem to have a conversation with everyone on the train.
Having lived in both Australia and Japan and visited SK, for me it seems like it’s rude in all those places but only in some places do almost all the people care what strangers think enough to modify their behaviour. Which is not as judgmental a statement as it sounds like, because that care, or some might call it pressure to conform, has upsides and downsides.
Yeah, to clarify my comment, I think it's rude everywhere and I suspect many others generally also, but I've only experienced feeling I couldn't do it/people will absolutely stop you in SK/JP. I've been on trains all through Europe, the UK, almost all of North America and usually hear someone on the phone, but nobody ever says anything.
It's considered rude in Belgium, at least when I commuted there by train. People would leave the wagon to take a call. Maybe it's changed in the past few years. There were also signs that it's prohibited to call in the trains.
There's usually some space between train coaches (I think it's called a gangway?) or at the end of a coach (a vestibule) that is separated from the seats area by doors on both sides. You can take your call there.
In London, subway cars are either completely separated and you can't travel between them, or it's just one long continuous tube, there are no vestibules. You don't get much signal underground either way, so it's rare to see people on a call.
Most trains however have a space [0] at the end of each car where you enter and exit. That space can also have a toilet, bike storage, various (locked) train controls, sometimes even a few seats [1] where you can sit if your call will be a while.
Leave the department*, the parts where people get on/off trains are closed off from the seats. There's also some gangway connections which have doors between the wagons.
UK, unless you are quiet about it. Though you might not notice as our reaction only tends to be in body language, or for particularly loud speakers (particularly those who are GOING INTO A TUNNEL or otherwise think shouting will help with bad reception) we might tut.
My dad speaks loudly on speakerphone phones in restaurants and public spaces daily because he's a rude old asshole.
No one beside myself has ever told him to stop because I think being old gives one a bit of a 'get out of jail free card ' with regard to social behaviors.
I would love for you or someone like you to happen upon him and tell him to knock it off, but alas that seems fleetingly rare.
Designing a non humanoid robot is the way to go. The design of new tools and appliances for hybrid human/robot use will eventually follow: the zip line for the shoe bag required way too much precision work.
I can't believe someone shares my point of view. We have already many non humanoid robots to do boring stuff (underwater maintenance, stuff like that). For some reasons people tend to think that for robots to do stuff close to humans, we need human like robots.
We do not. I want a swarm of insects-like robots to fight mosquitos. A snake one that fixes my pipe. A spider-like robot that cleans surfaces. Etc.
I think this perspective is now demonstrably false. It was basically the defacto position of most roboticists until a few months back. But we've already seen the cost of humanoid robots fall precipitously (even without the kind of mass production that genuinely useful home and real world intelligence would bring).
Which seems more likely, that cheap humanoids will continue to improve in dexterity, battery life, strength etc. Leveraging the vast investment in research into real world task training. Or - that we'll redesign millions of everyday objects to fit the limitations of current task specific robots?
If you answer the latter, I've got a whole bunch of mid century quirky labour saving inventions in the back room I'd like to sell you.
The robots linked above wouldn't be capable of vacuuming either. My point stands - the world is made for humans, we might remake an aspect of it for new vehicles that provided some radical advantage (as we did with airports or roads, although that would be a much larger undertaking with the level of complexities cities have today). But we're certainly not going to have twenty different labour saving devices roaming our homes, nor are we redesigning homes to facilitate such robots.
So if we do see domestic robots, they'll have to a) perform multi-domain functions, and b) fit into existing domestic spaces.
Long term, any generally useful domestic robot would have to have a pretty deep capacity for autonomy across a range of tasks - whether it's role specific or not. So it follows that it's much more likely we'll introduce humanoid robots (which already exist, starting at 30K), with the capacity for a wide range of subtle movements, and gradually add skills to them over time.
We already have roombas and dishwashers. I can't see us adding dedicated laundry folders, dedicated chef robots etc. There are social considerations in addition to the level of goofery that having numerous different devices to house and charge would involve.
Personally I’d love to see a general purpose machine, able to do all works demanded. This kind of vision doesn’t require any imagination: it’s easy to envision a world where you just replace humans by a human-shaped machines with perfect dexterity doing all sort of tasks. Voilà and welcome to the future!
But I still need to see a convincing humanoid doing even the simplest actions like grabbing a soda can from the fridge (from behind the cake), open it, and pour it into a glass and bring it to my desk, possibly in less than 60 minutes. It doesn't matter if it costs 30k if it can’t do anything useful for now. The gap is still too wide and far far away. Hence the missing “proof”.
Delivery robots in the hotels in China have the shape of a bin, not of a maid.
I will suggest mix of both: some everyday tools are already built for being used with hands and legs (e.g opening a door). But indeed adding some different grip types, additional arms, etc, could be helpful.
> And there was a lot of billboards in front of these manufacturers' shops. And when they uncovered, we could see through the window a lot of Bolivian people like sleeping and working at the same place. They earn money, just enough for food. So it is a big social problem that was uncovered, and the city was shocked by these news.
Wow it’s like when I move some pieces of wood or other items near my shed outdoors and I see a bunch of activity that I never knew existed.
Being able to paint the facade of a 20-story building must have felt ultra powerful.
