Meanwhile my personal installation is 8 years old. It was initially installed on a desktop on btrfs and has since moved between three laptops and across to ext4 and now xfs. 150K lines in pacman log file. I love it.


GDPR applies to any company that offers services to EU residents. It doesn’t matter if the company has any presence in the EU.

Now, that means EU may not necessarily be able to force the company operating in a different country to pay up but if a company has any significant EU customer base, I assume they will play ball.


One wheel scooter are generally more dangerous than their two or more wheeled counterparts because upon software bug or power loss, all control is lost. At higher speeds, serious injury is very likely.

Fuck ye!


Implementation of EVERY service on AWS is unnecessarily complicated. Not an exaggeration. Making things simple takes considerable consideration and effort, and that costs money. AWS is a nano-margin business. As long as something works and doesn't fall apart, they ship it.


> Elon is a fake person created by VCs to fulfill their goals.

I'm gonna give you a bucket full of benefit of doubt and assume you mean nothing negative by this. I'm all for fake people fulfilling VCs goals if that means we can have better and more exciting future (which Musk has delivered to date).

It's worth mentioning that many other "real" people with "no" hidden agendas have done ... jack shit over the past 20 years. :)


What did he deliver?


Assuming you’re sincerely asking this to learn, I suggest you ask Google, and read some Wikipedia to boot.


Ok, his rich family gave him some money to invest and got lucky with paypal. Then he became a hypeman for Tesla and routinely lied about full self driving in order to keep Tesla from bankruptcy and produced unsafe and poorly built cars. Then lied about trucks, roadsters, and solar roofs. He's speed running the history of tunnels and trains and will find out that, yes, putting independent cars in a tunnel is a dumb idea. Hyperloops? Seriously? Buying twitter blue checkmarks only to introduce another checkmark for verificaiton. Hm..Space-X is sorta futuristic? He hasn't proven reusable rockets have saved orders of magnitude of money.


:D this is like giving someone a smartphone and watching them trying to crack open nuts with it. Sad but also hilarious.


It’s undeniable, no matter what you think of the character, that he created huge momentum in the transition to EVs.

Also, rockets.


What are alternatives to Falcon Heavy?


My humble boot installer, no explicit bootloader, straight to the kernel:

    #!/bin/bash
    set -ueo pipefail

    # Remount EFI partition read/write and restore to readonly when done

    trap 'mount /sys/firmware/efi/efivars/ -o ro,remount &>/dev/null || true' EXIT
    mount /sys/firmware/efi/efivars/ -o rw,remount &>/dev/null || true

    # Remove all existing Arch Linux entries

    efibootmgr | grep 'Arch Linux' | grep -Po 'Boot\K\d+' | while read -r bn; do
      efibootmgr --delete-bootnum -b "$bn" &> /dev/null
    done || true

    # Install boot entry

    efibootmgr --verbose \
      --create --disk /dev/disk/by-id/nvme-abcdef --part 1 --label "Arch Linux" \
      --loader /vmlinuz-${_linux} \
      --unicode "initrd=\\intel-ucode.img initrd=\\initramfs-linux.img OTHER-KERNEL-BOOT-PARAMS"
EDIT: added initrd boot params


If you want to add an initrd, create an EFI payload: https://wiki.archlinux.org/title/Unified_kernel_image#Manual...

$ stub_line=$(objdump -h "/usr/lib/systemd/boot/efi/linuxx64.efi.stub" | tail -2 | head -1)

$ stub_size=0x$(echo "$stub_line" | awk '{print $3}')

$ stub_offs=0x$(echo "$stub_line" | awk '{print $4}')

$ osrel_offs=$((stub_size + stub_offs))

$ cmdline_offs=$((osrel_offs + $(stat -c%s "/usr/lib/os-release")))

$ splash_offs=$((cmdline_offs + $(stat -c%s "/etc/kernel/cmdline")))

$ linux_offs=$((splash_offs + $(stat -c%s "/usr/share/systemd/bootctl/splash-arch.bmp")))

$ initrd_offs=$((linux_offs + $(stat -c%s "vmlinuz-file")))

$ objcopy \

    --add-section .osrel="/usr/lib/os-release" --change-section-vma .osrel=$(printf 0x%x $osrel_offs) \

    --add-section .cmdline="/etc/kernel/cmdline" \

    --change-section-vma .cmdline=$(printf 0x%x $cmdline_offs) \

    --add-section .splash="/usr/share/systemd/bootctl/splash-arch.bmp" \

    --change-section-vma .splash=$(printf 0x%x $splash_offs) \

    --add-section .linux="vmlinuz-file" \

    --change-section-vma .linux=$(printf 0x%x $linux_offs) \

    --add-section .initrd="initrd-file" \

    --change-section-vma .initrd=$(printf 0x%x $initrd_offs) \

    "/usr/lib/systemd/boot/efi/linuxx64.efi.stub" "linux.efi"
The resulting linux.efi" can be added directly with efibootmgr, and contains the kernel boot parameters (cmdline)


uh - you just specify the location of your initramfs in the kernel boot params and that's it, no need for all the above


You hadn't specified it at first, so I thought it might be helpful to provide a more complete example with different parts (like the initrd) and offsets, with a gummiboot stub


Having kernel and initrd separate makes things more complicated and brittle.

Also a secure boot setup is much more difficult this way.

I for my part love the UKI. Never had a simpler boot setup!


> a secure boot setup is much more difficult this way.

Is it? Don't you just sign the bootable kernel image that already has the initrd and command-line built in?

Oh, I guess if you're using Microsoft as a CA I can see why that would be tricky.


I think this is a misunderstanding. I've said secure boot is much more difficult in case kernel and initrd are separate.

In case of a UKI it's very simple of course. Just sign the boot image.

That's why I love the UKI. :-)


> It is simply (physically) not possible for the existing cameras to see the area directly in front of the car.

Think about how a human driver does it, given his/her even worse vantage point. They model what's in front/behind the car from afar and remember what's where as they approach it. There are other signals as well, such as continuation of a kerb, etc.

I think people keep forgetting that Teslas run hundreds of ML prediction tasks all the time. Watch recent AI day and their talks about "occupancy network" to get a sense of the car's ability to:

1. Construct 3D model of its surrounding in real time; 2. Remember occluded sections based on what's it's seen previously.


Human driver constantly turns head around to where he is Mos likely to hit something.


Well, the car has 360 degree camera view, with far wider coverage than a turning head in a driver seat.

And more importantly, it sees in all directions at all times.


Well watch it again and again and again. He talks about the determental effect of lo-fi sensors in conjunction with vision among other things.


Here's the summary (mixed with observations from Munro and past Tesla presentations):

- Costs money: the physical sensors (a dozen of them), wiring it up, assembling it, maintain inventory, code it, etc.

- Time spent on maintaining, improving software stack for the non-vision sensors as well as efforts needed to fuse the data with vision, takes away from focusing on vision alone. It also holds back vision in relevant areas.

- Existing non-vision sensors used by Tesla are orders of magnitude lower fidelity than vision. It has historically (as the case with radar) led to vision essentially having to overriding radar because vision just performed much better (see AI day 2021).

My take:

As with any new tech, it likely sucks at the start (think HDD and SSDs, and how a mechanical thing with lots of moving parts was way more reliable than SSDs at the start). However, by essentially moving past the local maxima, you get to innovate better, faster in the future.

In case of ultrasonic sensors, they are for low speed cases anyway and most people are fine without them. Majority of fatalities and injuries happen at higher speeds.


That's great for them. But when I'm shopping for a car, I get to choose between a manufacturer that installs the extra sensors and seems to be able to get them to work, and Tesla.

Used to be that Tesla was blazing a trail and if you wanted a good EV, that was what you got. Now, if you want the best EV, it's usually not going to be a Tesla. And I don't see that they're making any decisions that will regain them that title. The incumbent manufacturers are quickly proceeding to eat their lunch, just like many of us predicted would happen. Turns out the hard part of making a successful car isn't the drivetrain.


> Now, if you want the best EV, it's usually not going to be a Tesla.

Would love to hear what you consider "good" and what specific EV ticks the most good features that a Tesla Model 3 doesn't.


360 degree camera on BMW i4. Overall build quality too.


I don't know if you're addressing what makes a good "EV" or just listing some features you personally care about. If the former, then 360 degree camera and build quality has little to do with an EV. Tesla is a young company and build quality has dramatically improved over the years (see Munro) and will continue to do so. Tesla has close to 360 camera coverage, it just hasn't added it in software. All it takes is a software update on existing hardware. If they haven't done it yet, it probably means they have other priorities at the moment.

Some EV specific advantages of Tesla over competition:

- Range: Teslas continue to lead in range, as result of best aerodynamics, best drive train efficiency and vertically integrated design (see Munro - highly integrated component).

- Charging infrastructure: largest available and most reliable (see MKBHD for e.g.).

- Regular software updates improving everything from range, to charge planning (recently added much better estimate based on wind direction, inclination, tyre pressure, weather, etc) to safety, etc.

- and most important of all: Availability and production volume. Best EV in the world isn't worth anything if you can't buy it.

If you look forward and see what Tesla is doing with its manufacturing innovations, it should become clear that things like in-house battery production, single front and rear casting among numerous other things has already secured their top position for sometime to come.


Maybe in US. Tesla has nothing to throw against some serious cars like Mercedes EQS or EQS SUV. Hyundai is also catching up. Charging infrastructure isn’t an issue in Europe anymore and is getting better and better every year. Tesla supercharger for free at the beginning was a big deal. That’s why I am looking for used model X from 2017 right now. 5000€ in free electricity a year is a nice advantage. I also have open order for model Y performance from Berlin factory. Sorry, the lead time shitshow is similar to all others. Every month my order is being delayed by 2 months for months. I have only one additional option ordered - black color. Last time I checked delivery time was updated to “TBD”. Lol.

Edit: this year generous funding for new electric vehicles in Germany is about to end, that’s why the last months of 2022 are so chaotic regarding lead times.


> Tesla has nothing to throw against some serious cars like Mercedes EQS or EQS SUV.

Besides sensationalist comments, do you actually have a list of what areas the Mercedes excel that Tesla doesn't?

I can't take "serious car" seriously - like what, Tesla is kidding?


Let’s talk about my future Model X 2017 with free supercharging. The chassis is disaster from beginning to the end. The car has air suspension, it’s nice. But! You go with low setting, tires don’t last 10k miles. You go with high settings, axles are suddenly broken. After 60000 miles all parts under the car must be replaced. Not funny and not cheap either. Last car I heard of such nonsense was 25 years old Renault Laguna 1. Mercedes or BMW do not need chassis rebuild every 100k km.

Btw EQS has greater range.


> But! You go with low setting, tires don’t last 10k miles.

It's well known that EVs in general due to their weight, and especially those with high torque cause the tyres to wear out much faster than their ICE counteparts. 10K miles sounds too low. Would love to know why low suspension setting on a Model X causes much faster wear, and whether for the same efficiency/range on a different vehicle, the tyres last significantly longer.

> You go with high settings, axles are suddenly broken.

We know media is trigger happy when it comes to the most minor Tesla related incidents and yet, I've never, in the 10 years of following Tesla, heard about this one. Can you link to perhaps a bunch of these?

> After 60000 miles all parts under the car must be replaced.

Again, never heard of these issues and I watch daily Tesla news from multiple sources.

> Let’s talk about my future Model X 2017

I'm puzzled. Despite all the issues you listed, you're still going with Model X just because it has free supercharging? You do realize that broken axels can kill you, right?


This is typical thread talking about tyre wear: https://teslamotorsclub.com/tmc/threads/caution-model-x-hidd...

Nice tire on the outside, completely gone on the inside. There are now enough aftermarket parts and repair shops knowing what parts to replace and how to alight the wheels so that in low suspension setting the car is usable for long time. Sadly full air suspension potential can’t be used, but I can live with that. Internet is full of aftermarket parts claiming to solve these problems for all Tesla models. Finding proper repair shop is however hard. Love for details is not popular trait between underpaid mechanics.

I can tell you one thing: model X has no competition. Mercedes EQV comes closest, but is bigger and the range is very poor. VW buzz has no 7 seats and it’s price is insane. I also don’t like companies gazing apes: https://amp.theguardian.com/business/2018/jan/29/vw-condemne...


Actual interior controls, to start. Tesla needed to save money on the interior and the giant consumer grade LCD was a really great way to do that. But now that the incumbents have entered the game, the standards are going up. The Ioniq 5 has two screens, one in front of the driver, and actual climate controls. The Mach E has a screen in front of the driver, and actual tactile controls as well. This is basically true of all non-Tesla EVs now.

CarPlay? Almost all cars, expensive or cheap, have CarPlay. Except Tesla. And you can throw Android Auto in there too.

Rain sensing wipers. That work, I mean. A firmly established technology at this point that Tesla can't make work. Then they insult you by including substandard manual controls so working around it is a chore.

360* surround camera. You can say that Tesla might have enough cameras on board to do it if they want. But they don't seem to want. So that's a feature that does not exist on a Tesla that I can get on a number of other EVs.

Parking sensors. Blindspot warnings (actual working sensors like most regular cars have now, not the sometimes-it-notices camera-based warnings my Model 3 would occasionally give me). Radar cruise control.

The best hands free driving is SuperCruise, and I can get that on a Chevy Bolt EUV, which costs something like 20 grand less than a Model 3.

I can get OTA updates from other manufacturers too. Notably, without the 'screw you' attitude that Tesla has, where they happily turn off customer features they don't feel the customer should have. Everything from taking away battery range without permission to turning off radar hardware that is already installed. Tesla is a consumer hostile company.

You have a point with the charging network, though that is quickly becoming moot since the non-Tesla networks are collectively growing faster.

Range is good on paper for Teslas, but my real world experience is that my Model 3 never got anywhere near it's EPA rating, my wife's Bolt usually exceeds it. As a practical matter, my P3D had less actual range than the Bolt even though the latter was only rated at 259. At least the supercharger was faster, which meant I spent 10 less minutes charging on our regular 300 mile round trip to Grandma's house.

I'm in the market again for another EV, and I can't find a single compelling reason to go with Tesla. The Model 3 is arguably worse now than the one I bought a few years ago, whereas the competition has been adding new features every year.
