Not sure if you’re familiar with the Model 3 super bottle. Here is an overview of that from Jason Torchinaky (who used to design heat pumps for a living):

https://jalopnik.com/the-tesla-model-3s-superbottle-easter-e...

The octovalve heat pump in the Model Y improves the range by 10% (per an interview with Elon and Sandy Munro).

I’ll note that the total range of the Model 3 LR is 322 miles and the Max range of the larger Model Y is 316 miles.

This compares to the 111 miles of all electric miles in the Kia Soul EV, 258 for the Hyundai Kona, and 170 electric only miles in the Hyundai Ionia EV. To be fair, the press release is likely correct as in 2014, the Soul having that heat pump likely was industry leading. It isn’t even close to it today, and things like Tesla’s patented (but very strange) inventions like the octovalve are why.

Today Tesla announced the Model S Long Range Plus is EPA rated at 402 miles. There really isn’t any competition (thr VW ID.3 likely being the closest).
or you could be someone who is very confident about the future, (and maybe trusts in god if you like)

you could also live in a country with universal healthcare and a social support net, so that, even if you don't have/earn enough, you never have to worry about food, a place to sleep and your health.

to worry is more of an attitude problem than it is a wealth problem
Software Architecture Hidden Costs
Alrighty here's the first graph. Note that this is average speed, so any trips with an average speed near the right by definition have some parts of the trip faster than the average, so the actual drop at 80 mph isn't quite as severe as it looks.

https://imgur.com/a/c10NXaz

the reason for the cutoff is that because it's pretty hard to have a trip with an AVERAGE speed above 80mpg. It's very rare in my large dataset.
A monitor arm with rotation support helps with this! Useful if you're planning to have a long read session, since there is a bit of setup cost (physically rotating the screen and then updating your OS's display settings).

An iPad and an app like GoodNotes or LiquidText is a great alternative.
I assume you mean the i8? A quick Google says it never had a range extender option. The i3 is very much not a competitor on performance, it's a city runabout - the earlier/USA models had complaints (and a lawsuit) that the generator was not strong enough even for that use, although Europe/more recent models don't seem to have the same complaints. Maybe the range extender concept couldn't apply to a more performance oriented car without an impractically big/heavy generator?
omg great feedback thank you so much!
That’s the reason, right there. There are three very long and steep grades on that trip, which suck down range considerably.

I do have to say, the Superchargers along that route are located about 45 seconds off of the highway, and are almost never full. You’d have your choice of places to stop. But if never making even a brief stop is your requirement, then you have your answer.
> What's most striking to me as someone who has heard over and over again about how air resistance is a X^2 property, is the extent to which short (and presumably slow) trips punch above their weight in terms of range consumed per mile. From what I can tell, the actual cost here is the fixed cost of booting up some systems and electronics, and the variable costs of running them over fewer miles can make the MPGe drop. Starting and continuing to run the AC adds up!

Could this be due to the battery not being at the ideal temperature on short trips? I always noticed that the efficiency of my car is lower for the first 10 miles when commuting to and from work. Since it happens in both directions, it can't be due to terrain or road type so I was guessing battery temperature.
I like the brutalist comparison. And it's why I ran 2000 server as a desktop for a long time. I wanted efficient, functional and worked well...pretty was not gonna pay the bills.
These days it usually means Facebook Messenger. FYI, not snarky. :)
Yes, this is why they have these tests attempt to do this in an apples to apples fashion, and the most scientific of these tests seem to show Tesla overestimates their EV range the most of any automaker.

Due to the built-in OneNote support, Edge is my go-to for PDFs! It also doesn't suffer from Chrome's limitation for the number of PDFs that can be open at once. Edge enables my questionable habit of depth-first reading :)

I tried new Chromium-based Edge and the new PDF experience is significantly worse imo. I downgraded and will stick with classic Edge as long as I can.
I take it as the CEO left for reasons stated at the time as other than this incident, when in fact eBay actually knew about the CEO’s involvement but hoped the real reason wouldn’t ever come out.

End of an era. I grew up learning how to use Flash and did little animations and even some websites in it. It was a lovely platform for non-programmer types.
It says "price coming soon." It's fair to predict that it's going to be really high.
Wow I did not even know we pushed that out live! Thank you for digging it up and sharing!!!!
Yeah, thanks, you make good points here and I agree. Companies should certainly refuse service to government entities in certain cases on ethical grounds.

I think there's a moral component and a practical component. The latter becomes very difficult when taking a stand against a government entity in your home jurisdiction, since the offending government may put you out of business or something.

For example, in Nazi Germany (which I agree is a useful example to reference), a company that refused service to the Nazis would have had its executives murdered and been taken over by the state within a day. (My guess based on my recent read of The Rise and Fall of the Third Reich, but I may be off).

On the other hand, refusing service to North Korea (sanctions aside) is a clearly ethically correct thing and offers little practical risk for companies based in the West.
Interesting, you must have worse infrastructure where you are. I have never had any problems in Scandinavia.
> Maybe in your country blind, extrajudicial violence is not a no-no. This is not the case in democratic countries.

Police all around the world use non-lethal force when the law is being broken and the perpetrator is not cooperative. This is absolutely not blind or extra-judicial. The whole point of this is to deter this kind of behaviour, and police are equipped with batons etc. for this reason.

> This is a) a slippery slope (a corrupt government would declare a curfew every time it wanted to stop protests)

I would agree if this was the case in this instance but this is not the case - there was a very obvious need for a curfew given the breakdown of law and order. Death, destruction of property, theft, loss of livelihoods. This is not what one expects in a civilized place.

Material wealth is a disingenuous framing. Someone's grocery shop is not accurately categorised as material wealth - it is their source of livelihood and it is a resource for the neighborhood. As President Obama pointed out in his letter, we all watched that poor old lady sobbing about the fact that she had nowhere else to go to buy groceries. To dismiss this kind of destruction as loss of material wealth is not at all accurate.

> Social equality movements have produced riots since time immemorial. Do you denounce the acts of Spartacus? The peasants revolt? The French revolution?

I denounce anyone who sets the shop of a small storekeeper or restauraunteur on fire, destroying their livelihood. You can go out into the streets and protest but this kind of behaviour is unconscionable and wrong. Setting fire to low income housing? How does this behavior help anyone? It's despicable. Your country can afford to build actual homes for low income folks while millions live in abject poverty and some rioter burns it down, and others justify it as a legitimate protest.

You can enact social change through all sorts of violence but it is most certainly not something that decent and civilized people ought to support. Everyone is rightfully furious at the incident that sparked this entire ordeal. The police presence on the streets was essential given the degree to which people were misbehaving and committing crimes.
This happens way too often. They often read a blog that talks about how X was implemented at company Y and mindlessly cite the blog for their own related-but-different-in-important-ways ideas and it’s upto the engineers to fact check the wackiness. It’s not pleasant.

This happened to me recently where a PM shared a blog about someone who had built an “all encompassing multi cloud cost calculator” for their org and had blogged about it. The PM was naturally extremely excited but I asked him to find more details about the tool and if/how that can be used. Turns out even though it was supposedly open sourced it wasn’t really available to just anyone but the author promised he would release it in a month. That was over 6 months ago, no word from the author or PM.

These blog fueled hype trains are extremely destructive. It makes engineering appear trivial. Building useful tool might be easier now but it’s not trivial. And if a tool sounds too good to be true it probably is.

Hrm... According to Wired, Jobs did instigate:

"With the launch of the first iPhone in 2007, Apple declared war against mobile Flash. Apple is supporting HTML5 and its efforts have influenced the online video landscape significantly. Many major websites are starting to use HTML5, and video players such as Brightcove are serving up HTML5 videos for devices not compliant with Flash. Separately, Apple has worked with companies like YouTube to produce iPhone-compatible versions of their sites."

Practices as a Platform Engineer (2020)
We're already in trouble in so many ways! LOL
Nothing wrong with python or JS. But there are many things wrong with bootcamp / workshop people who come out just learning Python with some ML library or JS with some web framework. They don't know even basics of CS and arguably produce bad, inefficient code.

There is a famous word for latter - 'webshit'. The former doesn't have such a title. But there is an obscure one originating from a Slashdot comment IIRC something like:
'you are one of those data science idiots from python schools eh?'

Edit: I didn't mean disrespect to those doing meaningful research. But that's not what most of things sold as 'ML' are.
Indeed. My fantasies don't usually involve me being a curious mixture of absolutely terrified, sleep-deprived, and (in retrospect) woefully underprepared.
Range axienty disappears as you get familiar with driving an EV with trip planning. Charging time is already short enough with version 3 of Tesla Superchargers. Availability of charging points isn't an issue when you charge at home/work. Hybrids are just adding complexity, cost and air pollution.
ICE as an institution doesn’t even know what Github is, and they won’t blink an eye if suddenly it goes away. It’s ICE engineers lives which are suddenly miserable because they would have to deal with setting up new systems and processes for source control and bug tracking on top of whatever else they were working on.

Cutting off GitHub access to ICE engineers is like sitting outside their offices banging pots and pans together for a few weeks. A lot of people are generally worse off for a short while, GitHub revenue goes down, maybe they lay off a few engineers who were supporting that customer, a few news articles are written alternatively praising another step towards corporate activism or bemoaning cancel culture.

The most important part of convincing GitHub to cancel ICE to those who are rooting for it isn’t so much ICE losing access to GitHub, but another drop in the bucket toward normalizing the politicization and disruption of basic services to deplorable customers.

This would seem totally reasonable to me. It'll take more time, but I can also dig in and see the extent of the battery heater use.

My guess is it's often cold enough for the battery to need to warm up to be efficient, but not cold enough to make it worth it to turn on the battery heater. (Your point still holds in that case)

A piece of data I happen to remember, far fewer than 10% of supercharges have the battery heater on for any period of time at all.
Some were delivered immediately, some delayed hours, I know some texts were sent to me by my wife still haven't arrived at all.
Tho that only helps with certain things, depending on localization.

For example, the German version of Windows XP renamed the entry for "Software" to "Programme und Funktionen"/"Programs and functions".

It's something that even over a decade later keeps catching me off-guard because for the longest time I was so used to look for "S like software".

And Windows 10 did it again with the whole "App" thing where I'm still somewhat confused if that's the new name for software, or if I'm installing some kind of integrated gadget from the Windows store or what the actual difference between these two is supposed to be.
The author also talks about how land (actually mineral rights, but who's keeping track?) can be had for a few dollars which implies that the government is giving away land essentially for free to oil companies. Sure it could be, but pretty much all mineral rights that sell for the minimum bid will have no oil or value. The majority of bids that will actually be drilled on with likely sell for a very large amount. Only useless land is going to be sold for nothing act auction.

sigh Such a shame that the author decided to use deceptive tactics which really water down what the message should be: that the government should preserve the land and not sell mineral rights unless there's a very compelling reason. I mean, here I am defending the government when I agree with the overall sentiment that nature should be preserved!
I do have a bit of physics in my background. I read about Grassmann recently in a game programming book. Foundations of game engine development Volume 1 By Eric Lengyel ends with a nice explanation of Grassmann algebra.

The road to reality by Roger Penrose also has a treatment of Grassmann algebra in physics context.

I agree the library is likely a reference to the mathematician.

what stops you from using a few convolution layers and then use the GLN in the last layer? You achieve the best of both worlds if your theory is true.
> I’ll note that the total range of the Model 3 LR is 322 miles and the Max range of the larger Model Y is 316 miles.

That's a function of battery size. The maximum battery size of the current Kona, Niro, and Soul is 64 kWh. Batteries cost money. The Kona, Niro, and Soul are all less expensive than the top end Teslas.

> This compares to the 111 miles of all electric miles in the Kia Soul EV

Not the current model.

> There really isn’t any competition

Sure there is. Tesla used to be the #1 BEV maker in Europe. Now they're #3. That's competition for you:

But none of this answers the original question. In what way is Tesla's heat pump better than Hyundai's?

Yup. What we're hearing from users is going into YouTube and finding the workouts is kind of a pain, and then you also have to do the workout. Our user is crazy busy, mostly working parents, tiny slices of time in their day to workout. It's worth it to them to pay $20/mo to get a new workout texted. We have yet to see if LOTS of people want that, tho! Free is def a nice price.

>>> Master is a word. Slave is a word. Being words, they have a meaning.

Let me put it another way: "wimp" is a word, and being a word, it has meaning. Does that mean I should choose to call you a wimp? Doing that would be rude, but free speech, amirite?

> You, and I, are responsible for our own emotions. Once we start going down that road it will be very easy to do away with free speech because “emotions”.

Do you refuse to account for others' emotions in your actions "because of" free speech? You speak like you feel like that's how you should behave.

Like most things, there aren't hard rules set in stone for all time. Using "master and slave" in a computing context is becoming rude, and sooner or later those who continue to use it unapologetically will be frowned upon and judged. If you want to be part of that club, I suppose that's your choice, but it's not a stand for free speech or anything like that.
Yeah I know people really like their aeron chairs; I'm just gobsmaked by it and don't understand why. I've sat in all kinds of chairs and while some of them kind of suck, there was nothing special about aeron chairs other than their price. To me they were a standard office "bucket seat" with too many adjustments. Would rather OP's regular wood chair!

I seriously doubt it. The population of Chile in 1969 was about 10 million. Let's say that, at its peak, there were one million people working on the Apollo program - which I think is a vast overestimate, but still. Even if all of those people were working full-time on Apollo, their labor and material inputs to the program were only a fraction of their total economic lives - they still had to make decisions about housing, food, clothing, transportation, etc. that had nothing to do with putting men on the moon.

And that is to say nothing of the fact that a space program is very, very different than a national economy.
The only low-level thing I noticed about the native Web Crypto APIs is its reliance on typed arrays. The speed difference is night and day as the native stuff can be hardware-accelerated by dedicated CPU instructions.

Browser support is very good: https://caniuse.com/#feat=cryptography

Documentation is also very good: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypt...

In terms of "ease of misuse" it's debatable. One of the biggest default security improvements with Web Crypto is that *cryption keys are _not readable by JS_ once instantiated - they can only be used by the cryptographic functions (unless you explicitly make them exportable). This is a subtle but very important defense against certain drive-by attacks that could dump loaded keys from whatever non-native JS crypto library you might be using.

In general I don't think it's safe to be using crypto at all outside of basic stuff like password hashing if you don't have a basic understanding of concepts like salt lengths, block cipher modes, hasher output sizes, etc. so I don't really agree with the "easier to misuse" statement. Some library that holds your hand more isn't going to significantly make things safer.
I challenge you to try our ab workouts for 30 days ;) You would be surprised. We start with a basic fitness assessment to measure your upper body and core strength. Unless you are already starting out in the 90th percentile, you will most likely experience a 20% gain in ab strength after 30 days if you do the workouts every day. This is what the data is telling us after a year of tracking users and their results.
Yes this example is very pertinent to Amazons profit strategy thank you for sharing.
This has been discussed here in the past, but since it's Musk's (Who can do no wrong) word against some nobody's, it has never gotten much prominence.
Definitely agree with you there.

It's definitely a moving goalposts argument. It used to be the claim that there were no EV chargers so the point was dead. Now there are superchargers across the states. To me, 250 miles of REAL range is enough for most people. I've driven 1000 miles with no real issue. Running out of battery, every few hours, almost coincides with having to take a leak and buy a drink. My car is good to go after I finish all those things.

There are still pneumatic controls operating HVAC equipment all over the place. A lot of it is being replaced with electronic temperature controls as the service life of the existing HVAC equipment comes to an end and it gets replaced. Facilities are now looking to interface HVAC temperature controls in with wider building automation systems.

The only context I see pneumatic controls in is a system to be demolished and replaced, so it’s neat to see how they work and how they’re functionally equivalent to electronic logic gates.
