You don’t need a supercharger to charge or even to fast charge. Other chargers work too. There are CHAdeMO chargers in a lot of places (need an expensive adapter, $450, but very worthwhile purchase). Mountain west? I’ve been seeing CHAdeMO all over the place… Grants, NM. Pagosa Springs, CO. Santa Fe, NM. Lewiston, ID. Taos has a surfeit of Tesla (non supercharger) connectors, most free! Or there’s J1772, everywhere practically, a slower option best for when you need to stop for other reasons, and the adapter comes with the car. Chargers are popping up everywhere. And electrical outlets are in every building pretty much so sleeping in the right place helps too.
But this is so convenient! "Your honor, this is the AI algorithm that said it was a gunshot, AI can't lie and is based on pure Science!" Yeah, later it turns out people made that decision because police asked them to do it, but the defense may not know it.
I had a similar false trigger trying to make an international call from our office phones. I didn’t know the exact incantation of the prefix, but knew it was 9 for an outside line and at home I used 011 then the country code. That didn’t seem to work, so I thought maybe I needed to drop the zero, resulting in me inadvertently dialing 911 and hanging up when that didn’t give me the dial tone I expected. I found the right sequence and was interrupted multiple times in the call as our floor fire coordinator showed up, then a few minutes later facilities, then a few minutes later local police.

I guess the system worked and I never forgot the correct prefix after that.
Not sure what you mean. The range of weights on any given adult bike beyond, say, extra small, are much wider than 20-30 lbs. It's exactly the same as a heavier rider as far as stopping distance.
A Dutch person wouldn’t be “able” to read Optiver in a Dutch way, though :p
This is a very interesting idea. I worry that the runtime overhead might be enormous (adding two numbers involves concatenating strings), and cause the space usage of the program to depend on its execution time. I think it's still missing something, like maybe keeping sizes of explanations reasonable by using a machine learned summarizer.

Basically... bang on for a code jam language.
While this is correct in theory, in practice there are many forms of golden handcuffs that make this a very painful option. In the final analysis, I think that many don't really care enough about the enterprise's overall success. My guess is that there are not that many well paying enterprises out there that are working on things that matter enough to care that much about...
Screw compressors are more well suited for high volume applications (like superchargers) than high pressure. This is because the geometry of the screws is difficult to sustain with very high tolerances. Small leaks aren't a problem when you're talking 10-50psi, but the 'high side' pressure of an A/C system is typically over 200psi.
"Large cars also reduce visibility which further reduces safety."

This is a flawed mindset. Anyone who has taken driver's ed knows that the proper solution is to leave more following distance if you can't see.

"There has been a car size arms race for the past 30-40 years."

Actually, car sizes have been getting smaller over that time frame. However more people are opting for larger types of vehicles like trucks or SUVs. You can't find a car today that has the same capacities and space that my old 89 Caprice had.

Edit: why downvote?

Edit 2: I guess there are a lot of bad drivers who won't leave proper following distance and don't want to admit it by commenting. It's always someone else fault when they can't see or otherwise safely operate their vehicle...
I can't wait for things like Hummer EV which might as well be a jumbo jet airplane compared to pedestrians, cyclists, hell, even other vehicle traffic.
I live in Australia we're not doing anything to help EV adoption.

A rest stop on the main highway between Melbourne to Sydney - a popular route without covid lockdowns... - will often have 4 chargers.

At Easter, wait times would be measured in hours if a significant number of vehicles were EV.

I've always left "location history" turned off, never found it useful enough to turn on at all... BUT I don't understand if that's even enough to prevent Google from having the records that can be accessed via warrant.

I have "location history" off, but I have "location services" ON, to allow for instance Google Maps to know my current location. THAT is useful enough I'd have trouble doing without it, Google Maps knowing my location (or uber, tinder, etc, things that won't work without it).

It's unclear to me leaving "location services" is enough to create the records that can be accessed with a geofence warrant? Even with "location history" off entirely/purged?

The article says: "collected from users’ phones when they use an Android device with location data switched on"

It doesn't sound like deleting old location history, or even turning off location history entirely will actually limit anything at all for these warrants?

Actually turning off location services might, but if you find it inconvenient to even turn off "location history", I don't think you'll like that solution much...
That 2nd link seems to be number of fatalities, which is largely going to be proportional to population.

To avoid looking at population and instead look at actual risk to a person, it should look at fatalities per capita.

That map is per capita without accounting for rates of car ownership or miles driven per day per owner.
"It’s the design with the massive fronts and massive grilles that are higher than the average male’s height."

it's true, that's exactly how we got our street tree, but a) it took an extremely long time to get the tree in the first place and b) the tree itself was rather lackluster, though now we're on year 3 of it and it's... ok. if I knew then what I know now I would've just gotten my own tree (one of the ones on the approved list) to get a nicer tree up front.

as for planting the trees without the permission of the resident responsible for that parkway, like I said in that previous comment, it doesn't do much good if the folks don't take care of them. we've also learned the hard way that doing things that seem additive to the hood are not always taken that way by neighbors and can cause conflict. been on the end of that a couple of times already. that said, maybe I'll stop talking about doing this and actually try it and see what folks say.
>That are different kind of children. In case of climate change it means the next generation of adults. In terms of cyber security it means actual children and is simply used to trigger protective instincts and make counter arguments seems cruel and suspicious.

"Actual children" eventually become "the next generation of adults" so I'm not sure the point you are trying to make as you seem to be implying tomorrow's adults are more important than today's kids. Either way, society would be better if future adults weren't abused as kids.

>Especially because child porn isn't not the initial but followup crime. The initial one is the actual abuse which isn't prevented.

You are assuming that all the abuse would still occur and none of it is encouraged by the demand for that content. I don't know why we should make that assumption. What percentage of traditional porn would you guess is documenting sex that would be happening if there was no demand for that content?

Not wrong, but it has been estimated that for every occupant saved by larger cars in recent years, 2.2 pedestrians have died. Not a great balance.
>> How exactly would that happen?

> How it always happens? How much time have you spend in multi-lingual contexts? How do you think creols and slang develope? Language naturally evolves to fit the needs of people who use it.

This is a failure to demonstrate how promoting language standards may result in increased discrimination.

Again, whether a language standard is promoted or not, people will discriminate against others who differ from them. The existence of a language standard removes the confusion and ambiguity as to what the correct form of the language is. This enables everyone to participate in the usage of the language equally.

> Funnily enough, your example, python, actually has two versions in use. If everyone refused to use python 3 because it was "bad python" then the communtiy would have been worse off.

Right and it took an official body with authority over the language to get everyone to reunite over Python 3. If no official body stepped up and no standard version was declared, there may still be large fragmentation between Python 2 and 3. Everyone clearly understands fragmentation of a language community is a stark negative. You are suggesting we pretend that a standard form of English does not exist which would only result in further fragmentation of English, which just as in Python, would be a bad thing for the community at large.

> Ideally you can also teach this standard without impicitly judging people as stupid and uneducated when they use their native dialect.

No one in this thread ever suggested using language standards for this purpose. And again, the existence of a language standard is largely orthogonal to this phenomenon. Judging people as stupid comes from differences in people, not language standards. In the absence of the existence of a “correct English” the judgements would transition from “you are not speaking correct English” (which is shared by all) to “you are not speaking my tribe’s English” (which is unique to a single tribe and would be a lot more tribally divisive).

> Who decides what is standard?

Whoever is the appropriate authority of the language. It could be a national government or an academic organization. Language standardization isn’t a new concept, nearly all European languages have gone through a standardization phase. It’s a solved problem. This is the equivalent of saying we can’t standardize Python because there is no obvious way to decide who is allowed to standardize it. That is just silly. Either an interested committee will form or a pre-existing authority will take on the responsibility.

Perhaps mod this into an airline-compatible e-bike?

Airlines which will happy carry a non-motorized bicycle as a standard checked bag, won't touch a motorized bicycle at all.

So a conversion which can be easily and unambiguously removed, might leave you with a checkable non-motorized bicycle, and unrelated, a small motor, some electronics, and perhaps a TSA-compatible small battery. Then add say a commonplace "portable power station" battery shipped to/bought at your destination.
Upside: there are very few indications for an MRI with contrast, and epidemiological studies have shown current gadolinium-based contrast appears to be well-tolerated (i.e. very low risk of nephrogenic systemic fibrosis in patients with renal failure). Downside: if an MRI protocol calls for contrast, then it’s necessary to use contrast to obtain the information desired (i.e. there’s often little use getting a non-contrasted MRI of the protocol calls for contrast but there is a contraindication).
I’m no apologist for new big cars, but…I was dropping my kids off at school and a 1st grader was riding her bike through the crosswalk and another driver didn’t see her. He bumped her at less-than walking speed so no one was seriously injured. I was amazed at how she bounced up and away from the car. If I would have hit her with my (old) truck, even at that super low speed, I’m sure she would have gotten caught on the bumper and pulled under the wheels. The new pedestrian safety designs are cool even though they do make all cars look the same and bulbous now.
You learn to shift your weight appropriately, but yes - definitely something to be aware of as it throws you if you're not expecting it. I'm speaking from experience on an electric longboard, but ridden both. I find the scooters you're more instinctively likely to brace on the handlebars.

Not to be trite, but cost is always important to the manufacturer. Tesla, for example, has been able to build a vertically integrated company through sheer will of its leadership. However, this is highly unusual and most product companies are going to want to invent as little as possible in order to ship a product. In this case a company wanting to sell an HVAC system based on this tech would have to develop the manufacturing pipeline to build these compressors vs. buying them from Copeland.

Now Copeland may choose to build these, but they are going to have to build the motor vs. buying them from one of hundreds of companies that build AC motors to spec.

Now one of those companies might decide to build these linear motors, but they are going to have to license the IP to do so, putting them at a distinct cost disadvantage vs. standard rotary motors. They are also going to be a sole supplier for some time, something manufacturers are very wary of unless it's a major differentiator. These are likely to cancel out.
You could use it to prove that you can not have been where the crime was committed :-)
> ruining them by bottoming out all the time

My daily driver has a spec of 5.9” ground clearance. In 21K miles, I don’t think I’ve ever scraped the bottom (except on snow piles, which aren’t an infrastructure issue).
Hopefully your motor will also work as a regenerative brake. But perhaps not every controller offers that?
This argument does not make sense.

1) +87% of the Swedish population live in urban area. (https://www.scb.se/en/finding-statistics/statistics-by-subje... )

2) Switzerland which is higher density has almost the same excess death rate (on your image)

3) France which had very strict and long lockdown (and killed/subsidized heavily its economy) has also almost the same figures.

As many have said, one of the major factor was how the elderly in home facilities had been protected and the state of the medical infrastructure (rate of intense care beds per capita to handle the peaks for exemple).

In the 70s and 80s, the Swedish medical infrastructure was one of the top. They still live on that legend. Please talk to Swedish friends around you and ask them how it is now (Part of my family is Swedish).
I'm not sure I understand exactly what you mean. I would rather read Select { $_.Property } than some awk or sed stuff to fetch the same thing any day. I'm not sure how this is different than most other modern languages used to write scripts.

Not in Europe because that would most likely be illegal.
They make me nervous, bc, as other commenters have pointed out- brakes, suspension, and traction matter a lot.

The difference between the cheap version of a motorcycle and the sport version isn't the engine, it's the brakes and suspension ( and now electronics).

But the main thing is the lack of helmets. One motorcycles, the center of gravity is low. You are more likely to fall and slide than go head over handlebars. At motorcycle speed, you should be wearing a full face helmet. I very rarely see the guys on e-bikes wearing full face helmets.

Then you look at the wheels and tires, higher speeds means more acceleration and faster stops, means more wear- which means much more maintenance. That most people aren't really paying attention to. Maintenance on two wheels is more than just a reliability issue, it's a safety issue.

Finally, people give no respect to bikes on the road. Especially in the US. You could be cruising along at 30 mph at the speed limit and someone will feel the need to pass you because you're on a bicycle.
"So the standard they met fails to even slow down the car when seeing an adult pedestrian at a speed that is a fraction of the driving speed in nearly every American city.

A handful of American cities have 25mph limits within the city but most drivers are driving at east 5-10 mph above that,"

So a fraction... but an improper fraction? 37/35 mph
As I understand it, that's actually rare.
You have the freedom to do whatever you want with the script. It's trivial to `exec >/dev/null 2>/dev/null` first thing in a script if you want it to be silent.
Yes, but raw YAJL (or its Yajl-Py binding, or other incremental parsers like jsmn) is a right pain to use while these are actually interesting in terms of API design.

I doubt your JSON reformatter was entirely correct (hey, we all must parse [X]HTML using regex from time to time), as you either have to pretend you can make sense of JSON using regular expressions (you can’t, no language or format supporting unbounded nesting can be regular) or write what’s essentially a standard JSON parser in shell with all the associated inefficiencies. My own needs are usually adequately served by the likes of jq -r ... | while IFS=$"\t" read -r ..., which feels much less hackish.

(Even correctly handling CSV with quoting, escaping, and embedded newlines in a UNIX pipeline without a purpose-built utility is surprisingly difficult—although not impossible, as CSV is a regular language.)
> what is there to gain by not getting up to speed on the design constraints by refusing to onboard or even engage with the maintainers?

Usually my only engagement with maintainers is when their library doesn’t do what I want it to do for whatever reason and is in the form of a bug fix (or less commonly an added feature).

I don’t want to ‘onboard’, I just want to use the software and since I spent the time figuring out why it was failing me I ‘pay it forward’ with what I found —- which is usually a diff of my changes.

Absolutely no desire to attend committee meetings to discuss the social ramifications of my changes or whatever they get up to these days…
On the balance, yes, but SUVs have their own risks, notably rollover due to the highest center of gravity.

Well, the article suggests that law enforcement -- mainly state and local -- is getting it from Google via "geofencing" warrants, "give me all the people who were in this area at this time". Getting it from google and not mobile carriers.

It would probably be a lot harder for them to get it from mobile carriers. There are multiple mobile carriers. They may not have the systems from which they could easily give law enforcement that data (Google has them, and uses the to respond).

Making things harder for law enforcement matters. But yes, of course you are more secure without your phone on you. (Then let's talk about the universal camera surveillance we have, and facial recognition... it is hard to be invisible in 2021, but that does not mean all venues are equal, it matters when you make it as easy as it is with a geofence warrant to Google).
Talking up echo chambers and how HN is special and not like other social media is certainly a great way to get karma on HN.
I wouldn’t be surprised if pedestrian use of phones (and to a lesser extent, medication/intoxicants) was a contributing factor in a significantly higher fraction of mishaps than in 2010.
Or at least that your phone wasn't... You could probably use it as evidence in court. I don't know how persuasive a judge or jury would find it.
No, you play a game that incentivizes walking and get a little rocker cradle thing that makes it appear to the game like you're walking many hours a day, then drop your phone into that before leaving.

--- Context (post by Ed Williams)

Most residential (and many commercial) AC units, refrigerators, heat pump and such use scroll compressors. Yes, they have a startup in rush, but I'd be interested in seeing efficiency of this tech versus current scroll compressors.

--- Post by "Just Have a Think" (the creator)

Response from Magtor CTO : There are many types of compressor in use and the industry somewhat specialises within particular technologies based on the power requirements, type of applications, manufacturing costs, end product costs, etc.

Regarding efficiency of scroll vs reciprocating compressors, not all sources agree but the trend is that scroll compressors are at least slightly more efficient, based on operating conditions…

There is this interesting white paper from Schneider Electric, “The different types of cooling compressors” https://download.schneider-electric.com/files?p_Doc_Ref=SPD_...
and I also found this study: “Comparison of hermetic scroll and reciprocating compressors operating under varying refrigerant charge and load” at https://docs.lib.purdue.edu/cgi/viewcontent.cgi?referer=http...
primarily by choosing an appropriate tree that doesn't do that. countersinking the tree can work in some cases too (often with a metal grating around the base of the tree so people don't fall in and hurt themselves). i don't know that you can "fix" the roots once the tree has become well established, without seriously damaging the tree and potentially creating additional hazard.
