pi-rat··on Tesla FSD Timeline
See, it figured out that the fastest route when summoned "from a home in L.A., to Times Square" is via the air. Smart car.
pi-rat··on GM says it's dropping Apple CarPlay and Android Auto because they're unsafe
It will also use knowledge about the destination to prep the car. Heading to a charger? It will prep the battery so that it’s at the optimal temperature for charging on arrival etc..

That said though, there are route planners that can give excellent range estimation (both for online and offline cars), by taking into account the terrain/temperature/etc, like ABetterRoutePlanner - ABRP

Don’t forget that you can often through-hole mount cheap readily made module boards like the one above. Often without adding height.
pi-rat··on Ask HN: Anyone Using MacBook Air M2 24GB for Developement?
Moving from an aging intel macbook to a modern m2 is a night and day difference, the passive cooling won’t limit you for most dev tasks you throw at it.

As for your throttling, I experienced massive throttling issues on a 2018 macbook pro 15”. Started out of the blue, and was so bad that I couldn’t even do 15 minutes of video meetings before audio and video lag and break ups set in. Lived with it for weeks, until I tried resetting the SMC - which worked like magic! Machine returned to its former glory. Worth a shot in your case as well.

Other things to try if the machine is aging, is to open it up, clean all the dust, and reapply thermal paste. It might be all clogged up depending on where you’ve used it. Aging thick thermal paste can be pretty bad as well.

pi-rat··on Ask HN: Does your microwave interfere with Bluetooth? Mine does
My first microwave absolutely wrecked 2.4 ghz wifi, replaced it after a few years and the new one didn’t. Didn’t have many BT devices back then, but bet it would jam them as well.
pi-rat··on Memories from old LAN parties
Any lan party organiser or participant worth his damn knew a variation of K4HVD-.. by heart for those reinstall situations :P
pi-rat··on Tesla created secret team to suppress thousands of driving range complaints
And much more than one would intuitively think.

I just finished a long drive for summer vacation. Driving through Denmark (completely flat) at 130 km/h would absolutely wipe the battery, would be surprised if I managed even 350 km on a full charge. Driving over the mountains in Norway however, from 0m elevation to over 1000m and down again, at slower mountain roads (max 80 km/h), yielded almost 500 km on single charge.

I did not expect flat+high speed vs hill-climbing+low speed would be that dramatically different.

pi-rat··on Gitlab has introduced a five-user limit for free groups
Money is no longer free and abundant. Simply turning free investment money into growth and possible future revenue is no longer an option for most companies. Boards and bean counters have collectively started pressuring everyone to focus on revenue asap.
pi-rat··on Europe’s Longest Bicycling Tunnel Opens in Norway
I suspect he means the southern parts of the US.

(Which are the most car oriented states, IIRC)

pi-rat··on So you've installed `fzf` – now what?
`find` has to traverse the filesystem, which is pretty slow. `mdfind` looks up in an indexed database, which is very fast.
pi-rat··on EV batteries alone could satisfy short-term grid storage demand as early as 2030
What if your car battery had a chemistry that could sustain ~10000 cycles if well handled, and aging in general was a bigger issue than cycle degradation?

We’re approaching this with the recent LFP generations.

pi-rat··on Audi is converting all factories to produce EVs as it phases out gas cars
This is happening in Norway now. Used ICE cars are getting bought up by foreigners and then shipped to for example Lithuania.

Sadly paywalled, but you get the gist: https://www-aftenbladet-no.translate.goog/okonomi/i/69P7w3/n...

Speciality vehicles will probably be the last ones to be electrified. I've not yet seen an electric snow plow, or even an ambulance.

The city busses charge over night, and some (I believe) in the lull between morning and evening rush hours. High traffic routes can charge while running(!) using overhead wires (city used to have old trolley buses). See [1]. They'll connect and disconnect to the wired infrastructure on parts of their route. At 3:14 in [1] you'll see the moment of disconnect. At 4:20 it reconnects. These busses can run continuously.

Taxis in the city are 50/50 electric and hybrid (prius) I would guess, just based on what I see on the streets. By law they have to all be electric by october 2025 in this county. Taxis have fast chargers next to their stands.

There are electric excavators and the like for inner city construction. Apparently some can run for up to 6h using only onboard battery. They usually drop some huge containers with charge ports near the work sites, which I assume extend this run time (+slow charge from the grid). You often see them connected with huge cables to these containers during static work.

Garbage trucks where I live are a mix of diesel and electrics. Majority is still diesel. Afaik the electrics run for a full shift. They're trying hard to get rid of garbage trucks where possible though, using underground pipes. You swipe an RFID at a "terminal", it opens, you dump in your garbage, vacuum pulls it to the incinerator facility, it gets burned, water gets heated, and then pushed back to homes as district heating. Obviously won't work for suburbia or rural communities.

Norway is already at ~80% EVs for new car sales. There are gas stations that are ripping up their pumps for fast chargers.
pi-rat··on PiBox: a tiny personal server for self-hosting
Another option is to buy a used "thin client". 1/10th the price, very similar power usage, small size. Some of them got room for a drive or even a quad intel nic (via pcie)

Gaggenau got knobs, pricey though.

pi-rat··on Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro
We don’t know yet, there could be some binning involved.

They could be identical, and the choice is just different thermal envelopes. Active vs passive cooling can make a huge difference for some work loads.

pi-rat··on iPhone 12 and iPhone 12 Pro
What happens to metal objects (like keys, etc) in your pocket now that your phone is a giant magnet?

I assume the iphone is always magnetic, judging by the magsafe wallet?

pi-rat··on iPhone 12 and iPhone 12 Pro
Most non-americans probably? :)

It will become cheap enough (both hardware and subscription wise) that companies can include them in basically everything. That way you can't prevent your TV from uploading data to the mothership by not connecting it to wifi.

It's not a consumer technology.

pi-rat··on Pandemic sparked European cycling revolution
It’s also a very heavy bike, with a extra long chain, able to carry two kids and a load of groceries. The chain is probably under some serious strain when going uphill, even when correctly geared and well maintained.
pi-rat··on Ask HN: What are some good methods to prove current time?
You're looking for: https://opentimestamps.org

It builds a Merkle tree of hashed documents, timestamps it, and puts it on the blockchain.

pi-rat··on Pandemic sparked European cycling revolution
I live in a hilly city, and the green part of the city council here ran a campaign this year were they cover 25% of the cost of an ebike (up to ~$550 for bikes and ~$1100 for cargo-ebikes). Now I see Tern GSDs and Riese & Müllers all over the place. Bought one myself, and it really removes the hills from the equation when deciding to bike or not.

They got bike counters at major routes, but sadly haven't released stats for 2020 yet. Number of bikers have been at a stand still for the last 8 years, looking forward to see the effect of COVID + sponsored ebikes when the new numbers are out.

pi-rat··on French fathers will now get 28 days of paternity leave
I don't know about the other countries, but "most" Norwegians are house owners (and therefore have pretty large debts, up to 6x their yearly income).

The government offers heavy incentives that promote owning a house/apartment, making renting long term a pretty bad economic option. If you plan to live somewhere for more than 2-3 years it's cheaper to own than to rent.

pi-rat··on French fathers will now get 28 days of paternity leave
Correct, we did use our (combined) 10 weeks of vacation to create overlap though.
pi-rat··on French fathers will now get 28 days of paternity leave
Apparently yes: https://www.businessinsider.com/countries-with-best-parental...
pi-rat··on French fathers will now get 28 days of paternity leave
I think it's quite healthy for the business TBH. In Scandinavia this is the norm, at a medium sized company there will probably always be someone on parental leave at any given time. You expect it, and therefor deal with it by reducing the bus factor up front.
pi-rat··on French fathers will now get 28 days of paternity leave
28 days? That's barely enough to get your head off from work tbh. I just finished 133 days (at 80% pay) of paternity leave here in Norway, and the last part was def more rewarding than the start as you hit your new stride and regular work life grew ever more distant.

All the organised toddler activities shut down because of covid19. Bought one of those child carrier backpacks, and we've been exploring forests and mountains almost every day this summer/fall, it's been a great bonding experience with the now 1 year old :)

pi-rat··on OpenSCAD - The Programmers Solid 3D CAD Modeller
I keep finding myself falling back on OpenSCAD when trying to 3D model after getting frustrated with steep learning curve advanced CAD programs.

Even if you don't like the OpenSCAD DSL (it got it's quirks..) there are usually other options in more familiar languages. I use it via Clojure[1]. It's pretty fun, even for small stupid things like coding up a rolling oloid[2].
