How does using instructions that operate on multiple data elements, which make your software 3 times faster, not fit the definition of SIMD-accelerated?
LinkedIn used to be a half-decent social network. There weren't too many updates, some were grift of course, but you'd also see former colleagues doing interesting things like startups or academic papers.
Then ChatGPT happened and dear lord did LinkedIn ever fall off a cliff. So, so many low-effort, zero-value updates. Far worse than any other social network I use.
I don't know, it was pretty bad before then too. Famously memed for the near psychosis level of shared performance art, where everyone had to present themselves as hobbyless, status hungry work machines. Maybe it was different if you already had a great network. Everyone I knew job searching hated it.
My father was deep into photography in that era and digitized all his photos. He was understandably paranoid about drive failures. The solution? ZIP disks everywhere! Cue massive family stress when the disk containing his competition entry was nowhere to be found and definitely in one of the kids rooms. It was, of course, found 3 days later in the glove box of his truck (thank you for reading my lowercase-t trauma dump).
And the last criticism is particularly silly. Do you need several hours to charge an electric car? Yes you do. Do cars spend most of their time parked in one place? You bet they do!
> Do you need several hours to charge an electric car? Yes you do.
No you don't. 20 minutes at a DCFC will get you to at least 80% for most EVs.
You need several hours to charge it at home, but it's gonna be at home for several hours anyways. With an L2 charger, you can go from 0-100% overnight.
DCFC does not charge "most EV" to 80 in 20 mins. There are some new ones that can do 10-80 in that time, but if you're lower than 10, or if you don't have a better-than-average late-model EV, it's going to be longer than that.
L2 charging usually happens overnight, but larger capacity batteries won't fill if you don't plug in early enough.
Like most people, my car is used for not just my regular trips around town, which I can certainly charge overnight no problem and be fine. My car is also used for the longer road trips.
It is 300 miles to my mom's house. Some electric cars could just make that in perfect conditions but give me a headwind or a cold day both of which happen once in a while and I can't make 300 miles on a charge and I will have to stop in the middle. At that point a fast charge is required. It is not acceptable to say I have to stop somewhere that I don't want to be for many hours to charge my car to get it the rest of the way. That is a trip where, if you have to make it, there isn't a better option. Flying would be even longer than driving by the time I get to the airport and rent a car on the far end, not to mention a lot more expensive.
At least in the U.S. it is very common for people to make a one or two thousand mile trip once a year for vacation. Particularly if you have a family, flying is not a reasonable cost and so you'll take those several days of driving to save money. Those road trips also let you stop someplace and see some weird small-town exhibit which is fun in its own way
> It is not acceptable to say I have to stop somewhere that I don't want to be for many hours to charge my car to get it the rest of the way.
I think the issue you're stuck on is driving an EV like an ICEV. When you're low on gas you stop, fill up, and continue. It's slightly different with an EV because you shouldn't fill up all the way on a stop. That takes so much more time because the batteries charge slower as they fill up. So if you want to get somewhere quicker you should actually be charging less at stops and stopping more often. I don't know about other cars but Tesla has a good route planner built in that does this for you and preconditions the battery while you travel to a fast charger, which is also important to reduce charge times.
No, I'm not stuck on that. A gas car refuels in five minutes max. Now certainly an EV from say 20 to 80% which is what most people talk about is done in 15 minutes in the best case but that's still three times longer and it's someplace I don't want to be. That's assuming that there is a fast urge during the location. There are a huge number of level 2 chargers scattered around the U.S. and level 3, although they're becoming more common, are somewhat rare.
In that 300 mile trip, there is a gas station every 10 miles. There is a level 3 charger every 100 miles. Which is to say, I certainly can make the trip in my electric car, but I'm I have to make sure I stop where there's a charger because unlike a gas car I can't say the gauge is getting low. I'll stop at the next exit. I have to say the gauge is at half per charge - I better stop at the next charger because I don't know if I can make the one after that.
I've done a 400 mile trip in a Model 3 Long Range and only needed three stops at L3 chargers. In winter, in Canada. With over eight hours of driving it's not unreasonable to stop for a few breaks, and you should be able to plan your breaks near chargers.
I have never spent this much time refueling my car. I don't think it's ever taken me more than 3 minutes to actually put gas in the tank. While it may be true that sometimes you have to wait 30-45 seconds for a pump, the wait times on chargers can be much longer because people spend 20 to 30 minutes at each charger.
Yes, I understand that some people will present contrary anecdotes, but AAA says the average is 15 minutes. And I trust them more than I trust anecdotes from random strangers who show every indication of motivated reasoning.
And to share my own anecdote, I've never once waited for a charger.
15 minutes seems long. That implies a lot of people are doing something other than getting gas. I guess on a roadtrip I will sometimes eat in a gas station which takes longer - but I don't eat in my car - an unusual rule.
Total stop time is not just time spent standing at the gas pump but includes things like going to the bathroom and getting snacks or drinks from the convenience store.
The great thing with an EV is you don’t have to stay there while it charges, so you can do those things in parallel.
You may be thinking of a different context. This is about road trips, not around town fill-ups. On a road trip, people stop to fill the car, get snacks, take a leak, stretch, etc, which is why the average tends to be 15 minutes or so.
You can do faster stops for the weekly fill-up, certainly. But in that case the comparable situation in the EV is zero minutes. The vast majority of owners will spend far fewer minutes on refueling for their EV in a given year even if the road trip stops really did take two or three times as long.
There will definitely be a lot of variance to it. Tank sizes. Pump speed. Some people exclusively fill up at Costco where lines at the pump can be longer. Some shop around a few stations to find a slightly better price. Some make a separate trip to a station at night because they lower prices a bit then.
> Some shop around a few stations to find a slightly better price.
And those people are often bad at math or grossly undervalue their time.
Some people drive 10 minutes out of their way (20 min round trip) to save 5 cents/gallon. Even if you have a 20 gallon tank, that's only saving $1.00. I wouldn't take 20 minutes out of my day just to save $1, even 15 years ago when I was living paycheck-to-paycheck on $10/hr.
It's interesting to think about because we should start seeing a decline in gas stations as EV adoption picks up, which flips the problem around. We're definitely nowhere near that now though.
My ancient 2015 Model S 70D would do that 300 mile journey with less than an hour of charging in the middle. A new car with much less time for charging.
I've just done a thousand mile journey from UK to Norway in that car. It was not a big deal to charge on the way and would be less so in a newer car.
But some people here claim that you don't need a charger at home to have an electric vehicle. That's equally silly, but in the opposite direction. If you don't have a charger at home or work, your experience with an EV will generally be quite subpar.
I’m don’t do much change-clicky-button software development. But when I do, I point models to specific lines of code. And have never had a result this bad.
Maybe this is geared towards pure vibe coders for whom a file and line number is too technical.
I am aware of the "eating wins races" strategy for endurance sports.
Glucose and ketone monitoring seems a natural, more precise extension of that strategy. Isn't the point of carb-cramming to get more glucose into your blood stream, where your muscles can convert that into forward motion?
Yes. But you don't need to monitor glucose levels to do this. Because it's well known you can productively use as much as you could manage to consume (without vomiting). So all the device will ever tell you (if you're in the middle of significant endurance event) is that you need to raise your blood sugar. It'd be no more actionable than a writing 'your blood sugar is low' on your hand with a sharpie.
