Agree. The key skillset I needed to learn was to get along with people. Being nerds, we think we are always right. Hello! The truth is that there is often no one true answer. Learn to bite one's tongue. Still hard for me to do - but I look at my easy-going my friends and see that they have had a smoother journey through life, maintaining their jobs for much longer than me.
295 mi commute? how many days a week is that monster?
Given that Tesla track everything on every car - where they go, how they drive, when and how much they charge - they ought to have accurate data themselves apart from EPA ratings.

Could customers demand their own data from Tesla? Europeans, under the GDPR, for example? If enough people did, and released it, that ought to be accurate.
The OS in the cartoon was called "Doors 2000". Seems pretty squarely targeted at this.
I make an app (called Nikola, not the truck company) for Tesla owners that has seen over 5 MM miles driven on it. I did some quick queries to validate actual range vs. EPA range for those curious.

My general takeaway is to see the EPA range as a useful, albeit unrealistic, indicator. Essentially nobody gets the EPA range, either because they choose not to go the speed limit, they accelerate harder than the EPA test factored in, or the vehicles drain some juice while parked.

The data: For the hundreds of Nikola trips with an average speed of 60 mph, the actual MPGe was about 102. Once you get up to a 75 MPH average trip speed, the MPGe drops to 94. And by 80 MPH the MPGe drops to 77. (avg over all Tesla types)

As a bit of "anecdata", I've driven trips where I hit my range on the nose, just to show I could, but the driving is less fun and I was going slower than traffic. I don't drive that way anymore.

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!

edit: have had some people ask. The app can be found at https://download.nikolaapp.com

I can also post data / graphs or make a blog post about that if people have more requests. Let me know what you'd like to see!
My point is that with a 100% charge from driveway to driveway, My 295 mile trip would still require a stop for a 20 minute charge (not counting all of the logistics associated with that).
As posted elsewhere in this thread, http://www.tesla.com/trips is still reporting the exact same numbers it was in January when I gave up and bought my new car.
Less than twice a month.
I think they realize all electric cars will not be the largest share of the market when hydrocarbon vehicles are phased out. The biggest reason for not owning an electric vehicle is the charging time and range. Toyota and Hyundai aren't going all in on all electric because they would rather focus on capturing the fuel cell market which will be as large as the hydrocarbon vehicle market is today.

I don't think regen braking is perfect (70% efficient maybe?). And if the battery is full, regen braking is disabled/lessened.

Maybe...if a carbomb is like vandalism, just with more resources at their disposal?
If you don't want to spend much, the TS-100 or TS-80 are both very good choices under $100.
The Model 3 with the current software in "Normal" regen mode does apply more regen when you use the brake pedal, at least as reported by the regen indicator.
No, T-Mobile forces everything through Inteliquent (aka Onvoy/Vitelity) as of a few years ago.

They all likely share the same STIR/SHAKEN vendor, and Comcast is affected too (Comcast has working STIR/SHAKEN that interacts properly with T-Mobile and Verizon). Wonder if their shared STIR/SHAKEN vendor broke these calls?
Source? I'd be willing to fix up house in Europe.
I'd be interested to know if the paper discusses how many civilizations they expect to exist in the Milky Way under the Weak Astrobiological Copernican scenario.

On an unrelated note, I laughed pretty hard about the headline:

The conclusion of the article - supposing that there are 36 CETI civilizations in our galaxy, then we are probably far enough away from them that interstellar communication is impossible for the foreseeable future.

The conclusion of the headline editor: SCIENTIST SAYS that we can communicate with 36 ALIEN civilizations RIGHT NOW!!!!
> the EPA has never tested one in their own lab.

That would make Tesla's prior claims about the EPA screwing the mileage tests up a couple months ago quite odd.

https://electrek.co/2020/04/29/tesla-model-s-400-mile-range-...

> The CEO claimed that the EPA left the door open and the key inside the car when stopping during range testing, resulting in the car remaining powered up and losing 2% of battery capacity.
Existence of a proof doesn't mean application of it is widespread.
At my son's school the parent involvement is high and the kids all engaged as far as I could tell.

A teacher at a rural school told me that they hadn't heard from half their parents or students since the schools switched to distancing learning despite calls and etc... not even once.

They don't know what to do as far as grades and etc.
Fantastic rabbit hole to dive into, thanks for linking!

The "good news" is that you can't even use tput rev under fish because it saves and restores attributes each time it regains control of the tty with very few exceptions , rev not being one of them. You can't break what you don't even support!

(Seriously though, we should add rev support.)

EDIT: I just saw that you're the same person that answered that post, which very much deserved the upvote. Your knowledge of tty behavior is impressive. It is also rare to find another person that cares about the kvt - a lot of apps that manipulate terminal attributes or use any vte codes are completely broken under even the well-written kernel virtual terminals.
Well, some companies seem to end up with weird incentives where it makes sense to be less productive. For example, a dev might create some script that eliminates some data processing roles. The CEO might decide to not implement it solely to save a few jobs. If there’s a tax for not automating then the organization will immediately respond in a more economically rational way.

In some jurisdictions being gay is a protected class, in others it is not. Even the USSC ruling today doesn’t create a new protected class; it simply (and correctly) determines that discrimination based on gender nonconformity (whether sexual orientation, gender identity, or other) is discrimination based on sex, which is already a protected class.
All I see in the video is a description of a heat pump. In what way is Tesla's heat pump better than, for example, Hyundai's:

https://press.kia.com/eu/en/home/media-resouces/press-releas...
All cars perform better (in terms of kWh through the driveshaft per km) at lower speed, since air resistance rises quickly with speed. Tesla can't do anything to change this, although they do try to mitigate it with good aero.

Electric cars can regen brake and so recover some energy in stop/go traffic, but they're still more efficient at constant low speed than stop/go at low speed.

ICE vehicles only get better economy on the highway because they have no regen braking and their engines are more fuel efficient at highway speeds.
It is worth recalling that in the early fumblings of the phone market someone tried to get Flash running on Android. It didn't work out particularly well, and all the high value customers kept buying iPhones and browsing webpages.

There is a pretty good argument that it was 0%/100%. It isn't like there is anything threatening to Apple that Flash could do that isn't theoretically mimic-able on iOS using Safari.

I would go with libsodium.js (which binds to the native C library in Node.js) if you just need to encrypt/decrypt in general, especially if you anticipate building out other cryptographic features in the future.

If you need AES in particular, node-forge is probably fine, although from a quick glance it looks almost identical to Node's built-in crypto API, in which case you could just use that, but they both look pretty inconvenient (excessively low-level) to use directly.

I cover this a bit in my post about the data I've seen in the 1000+ Tesla fleet that I track with Nikola. 75-85% is about I right.
I’m not sure whether you mean older teslas or older cars generally here. Small cars in the 70s and 80s weighed just over half as much as they do now. The Golf Mk 1 was 795kg while a Mk 8 is 1255kg. Much of that increase in weight is safety equipment and they are much safer for it.

Supposedly the “plaid” drivetrain for Model S will up the battery size again. I could see both vehicles seeing upgrades along these lines next year.
Beanstalk is cool. Just curious, in what ways could it be more simplified? I think we can already just upload our code and forget about it. It could be that I am missing something.

Metabase for data analysis. Admittedly not a service, but more than worth running a docker container yourself since it's FREE.
I really liked the i7, and I would have liked to stay with the BMW brand, but the poor thing had a 100 mile range. It certainly looked good, but it was even less practical than what I had.
Another fun fact on practical drain vs. EPA drain:

While I love sentry mode and think it's a great feature, it keeps the electronics awake. In some cases this can cause double digit per day mileage drain. Tesla has clearly been working on this though, as the numbers have improved.
"slaving" or "(being) slaved" as an intransitive verb has a history that predates modern computing meaning a mechanical or electromechanical system that takes its control inputs from another (master) source. Examples:

What’s a “basic liberty?” Who gets to decide? What happens if the majority literally believes that God will punish their society if it condones “sinful” behavior? You can say that religious beliefs shouldn’t be the basis of law, but who put you in charge? And what happens when people’s “basic liberties” conflict? Isn’t freedom of association a “basic liberty?” Is there somewhere in the constitution that says it doesn’t apply to employers?

I view the legal process like arguing with your spouse. Every win has a cost. Every victory for individual self determination achieved through litigation chips away at the right of collective self determination, and that’s not cost free.
I suspect you read quite a few biographies and liked that a few of them are sociopaths, identified with them, and you want to use that to justify sociopathic behavior under the guise of "it's what successful people do and I want to be successful".
I wouldn't hold my breath, CR is a husk of its former self and doesn't produce very much content anymore.

The main numbers that matter are:

- conversion efficiency of converters/inverters, if any

- efficiency of motors

- drivetrain friction

- tires' rolling resistance

- tires' air pressures

- wheels' alignment

- rotational moment of wheels (possibly)

- total weight

- coefficient of drag

which lead to kWh/mi or kWh/km, combined with usable kWh, results in range.

There's no cheating measured data or fundamental principles.
It’s like a weird kind of long-form submarine campaign ad with a click bait title.
Only if they don't disclose the serious risks involved, which they do, right up front in the very first few sentences of the filing.
Their trip planner recommends a charge in the middle for almost any trip greater than 200 miles. I am not sure why.

It also could just be a fairly hilly drive or a drive with a high speed limit. Either way it’s pretty unfair to say Tesla is outright lying because the stated range isn’t applicable to every possible stretch of road in the world.
I actually think VR and events could be magic. You put it on and for 2 hours do a combination of keynotes and chose your own adventure experiences. If it incorporates interesting enough visuals with content I’d much prefer this to going somewhere in person for the week or sitting in front of a “online conference console” with streaming video and a chat window.
I haven't used this, so I went and read the documentation.

node-forge is a good example of giving a user too many options in my view. As a developer looking to secure something, you've apparently decided on AES-256 against options like "DES" and "RC2" that are on offer. That's a good step.

Now you get to choose between ECB, CBC, CFB, OFB, CTR. Which is a good idea? Which isn't? The documentation appears to just say "here is a great example of using CBC mode". That example is vulnerable to a padding oracle (uses PKCS#7 and has no form of MAC). From what I'm reading it's left as an exercise to the reader to record the iv somewhere. If you did want a hash, it helpfully suggests MD5 as reasonable.

This isn't a great example of crypto engineering.
I saw an exobyte file created subsecond, just need to mess with inodes!
“Massive DDoS attack” just T-Mobile error?
Looks like the purported range is analogous to stated phone or laptop battery life: ideal and unrealistic. This makes sense because the car is, in fact, run by a battery.
It's worse when they /do/ want to be closely involved, but then also thinks that being closely involved means dictating functionality to a T.

Using software does not translate remotely well into /designing/ software. Too many people want to play small-time user interface designer while realistically having no design knowledge beyond "I've used software before, and I have IDEAS about how to do things better."

So much effort is wasted on implementing things people think they need, having recognized a problem and conceived one idea that might solve it if only someone could implement their vision.

I sometimes envision a world where (layperson) patients show up at a hospital with a medical condition, describe a novel surgical treatment to the physicians, and then the physicians follow their instructions exactly because, hey, why not? It might work! There definitely won't be consequences if it doesn't!
Ykk for zippers, though they got noticed a few years ago but the interwebs.
Dumber Beanstalk would be Heroku?
For the hundreds of Nikola trips with an average speed of 60 mph, the actual MPGe was about 102. Once you get up to an 75 MPH average trip speed, the MPGe drops to 94. And by 80 MPH the MPGe drops to 77. (avg over all Tesla types)

That makes total sense. What I think most people don’t realize is that power is force times velocity and the force you need to apply to maintain a given velocity is equal to the friction plus the drag. Unfortunately, drag increases with the square of the velocity and so when you go faster you need way more power. This translates directly into increased battery drain for an EV.

The problem may be further exacerbated by the greatly increased mass of an electric vehicle and the potential for the batteries to overheat.
This is why I bought a Kindle Fire. That is the only reason I needed a tablet which is why I postponed it for several years. And indeed this is the only thing I use it for.
This is such a good point! We definitely need to do that. What would convince you? The CDC guidelines for exercise
To maintain your weight: Work your way up to 150 minutes of moderate-intensity aerobic activity, 75 minutes of vigorous-intensity aerobic activity, or an equivalent mix of the two each week. Problem is most people aren't doing anywhere close to the CDC guidelines. What we're hearing from users is that they can't say they are too busy for a 7-minute workout...so they end up doing it. If you do 7 min a day for 7 days that's 49 minutes a week of exercise - which helps people build the habit and the confidence necessary to "work their way up" to the CDC's suggested guideline.

Ha. CTO at my last place did something similar. He hired an AI/ML team. I asked him what projects he had in mind and he said once the team was on board they'd find things to do. He also said we needed a voice app because he read an article about the size of the market. I quit before seeing how any of that worked out.
>In other words, some conferences are built around creating a network in the hallways. If you take them online, there are no hallways.

There are no hallways. Also, there are no side conversations, serendipitious encounters, forming and disbanding groups naturally, after-sessions social activities, or meaningful ways to gauge attention or intuitively navigate turn-taking. There's no forcing function of being in the same time and place among people of similar interests.

Online is fine for content delivery, so presentations and slides easily transition from in-person to remote. However, the medium doesn't conform to how people make actual human connections. Online events can be deeply frustrating because the social instincts we've honed since childhood are suddenly useless in that context.

Ideally, use a hardware token instead. They implement many different algorithms, so you should be able to find one that does what you need with your bank. See https://www.zdnet.com/article/best-security-keys/ for one good list.

Best I’ve found is to read PDFs on an iPad Pro using an app such as IAnnotate. Instead of scrolling, I display one page at a time in portrait orientation, and then you can swipe to flip the pages. Highlighting, underlining, and short notes are quick andeasy. You can keep all the documents in Dropbox for convenient synchronizing of notes.
I hope I didn't come off as overly aggressive, the comment was mostly for myself, I was feeling badly that there was no way I would be able to do implement something like this in 12 hours.

Often veterans here will talk about projects they trivially did. but unless you dig into their profile and find out who they are it feels like every joe-shmo on hn is a 1/2mil+ SWE at google.

seems like an apt comparison. Something I forgot to mention here is that the temperature also plays a huge role. I've recently started collecting more temp data, but don't have a big enough sample size to say anything definitive beyond "driving in cold weather does reduce range". This is completely expected.

As a bit of anecdata here: Parking inside vs. outside seems to have a big affect. A slightly chilly garage vs. a cold soak outdoors understandably are quite different.
You don’t want to drain to 0 anyway. To make a 295 mile round trip without a charge I would want a weighted range of 400-450 miles.
China Reports Progress in Ultra-Secure Satellite Transmission
Who was clamoring for the 9x kernel? No me nor any geeks I knew...

And as sibling mentioned, ME was before 2000. I remember this because at one point the actively marketed versions were Windows ME, NT and of course CE for those ARM devices. Some people, complaining Windows was slow, pointed out that if you rearrange those version identifiers you get Windows CE-ME-NT (cement).
Your rake analogy is a little flawed, just because those "known to the state of California...." warning signs are practically everywhere. If they were actually rare, and this rake was the only thing in the store that had the sign, and the store was requiring a liability waiver to buy one, then you'd have a much closer analogy. In that scenario, given the multiple warning signs (including an actual, literal warning sign), I do think it's fair to say the purchaser holds some blame for being a dumbass. The legal system might say otherwise, but, if you do something that you've been warned multiple times is really, really dumb, by who should know you're about to do a dumb thing, then personal responsibility needs to accrue somewhere.
I missed the parenthetical on your comment, my apologies. You're right: if you can monkey around with things enough to SSL-proxy the traffic, then rolling your own PKI will not help prevent that. What will help prevent that, yes, is pinning, but my argument above was that pinning to any single CA (or worse, any single leaf certificate) without a mechanism for replacement is what gets people into trouble. Selecting a small set of trusted CAs is a much stronger pattern, and would preserve the inability of clients to swap out their own certs or proxy their own traffic (although it may also break things—Google had to bend on that one a bit to allow for enterprise SSL decryption, e.g.).
