wallaBBB··on Philips and the death of Europe's last electronics giant [video]
But it also makes a point that it was a mistake to do so.
wallaBBB··on Philips and the death of Europe's last electronics giant [video]
I found this video quite flawed.

What happened to Phillips is something that proved beneficial in the long run.

Legacy of Philips is now ASML, NxP, pretty good startup scene in Eindhoven, and a few other companies. The only victim here is the name. If Philips tried to move as one company they would have probably dragged down their chip related businesses by siphoning money into the fields they were losing.

Of course one could argue that the company under Philips name should have chose different direction and spun off consumer or medical market, but at the end of the day it's just a name.

I believe in hindsight this will be a way better outcome for everyone than the one we'll see from big tech if they're not broken up. There are already too many examples of them killing competition by leveraging their monopolies or buying it up and killing it off.

wallaBBB··on After Delhi High Court ruling, Telegram discloses personal details of users
With the amount of fake news being pushed through Telegram groups that are public, Telegram is by far more Facebooky than WhatsApp. Ukrainian war disinformation and crypto scams being a good example of Facebookiness on Telegram.

wallaBBB··on Linus Torvalds to kernel devs: Grow up and stop pulling all-nighters
If people continuously fail to follow the process (and we're not talking about general population here) then maybe the process should be reviewed and changed so he does not end up with a two weeks work crammed into 2 days.
wallaBBB··on Jack Dorsey texts Elon Musk, March 26, 2022
From another Musk's conversation [1], if you ever wondered how you reach high management positions - hard work:

Musk: Please send me anyone who actually writes good software

Steve Jurvetson: Ok, no management good coders, got it.

Musk: Yes

Musk: Twitter is a software company (or should be)

Jurvetson: Yes. My son at Reddit and some other young people come to mind.

Venture capitalist Steve Jurvetson texts to recommend former Uber exec, Emil Michael, for the Twitter CEO job. When Musk says he’s looking for people who can code, Jurvetson volunteers his son.

wallaBBB··on Volvo is using Rust for its in-vehicle software
For ECUs running the car it's MISRA still, Rust is in the pipeline, but still far far away. 5-10 years before it becomes common. Standard is being worked on, but compilers and other tools will take a lot more time. These are generally not your of the shelf MCUs, and for many compilers are quite tailored.

But for anything regarding networking and UX (screens), a lot of languages and frameworks are being used right now.

Also, if you hate MISRA subset of C so much, you probably won't like Rust, since both impose some similar rules.

Question that comes to mind - Is M2 (with thermal issue on new Air) affected considering how RAM is packed there?
wallaBBB··on Rolling-PWN vulnerability affects all Honda vehicles
So someone can pick a lock on your door and hotwire your car and steal it. But with this attack they can only get access to the car. Hotwiring if there is an immobilizer is not possible.
wallaBBB··on Rolling-PWN vulnerability affects all Honda vehicles
1) long range replay attack are what is a real issue, and is solved by bi-dir fobs. Only thing keeping them out of the market as a default is price. Issue described in the article is far less of a concern than what you mentioned, I put it in the category of Intel's Spectra - where if you already have such physical access to the device/CPU, there are easier ways...

2) Price - just the MCU is more than 10+ USD. Those MCUs are basically ASICs with a lot of stuff integrated (plus - automotive rating). Precise and stable OCX doesn't come cheap either...

3)There is no single chip solution in the automotive market that would integrate all functions (LF Rx, RF Tx+RX, transponder Rx+Tx). Additionally, RF bi-dir + passive LF is power hungry, and getting a year out of your standard CR2032 forget about it - so a more expensive power source needs to be used...

4)NFC is basically just only one of the aforementioned functions - similar to transponder Rx+Tx.

5) Oh it needs writable nonvolatile memory for a lot of reasons... - configuration to cover different vehicle/market/protocol variants, DTC, Secret Keys for pairing, unless you want your fob replacement price to skyrocket...

Regarding fob price - keep in mind it's not just the electronics, although automotive MCUs have harder requirements to satisfy (op. range of temperature, voltage, very low quiescent current, very low ppm failures). Mechanics are expensive, although deceiving when you look at them. Keep in mind they go through some pretty nasty tests - including (and I kid you not) a washing machine test - basically testing if it will survive a washing machine.

Dude RKE is not the keyless you think, your probably thinking of passive keyless. This is pressing your LOCK/UNLOCK button, and if you have buttons on your FOB than you have this issue.
wallaBBB··on Rolling-PWN vulnerability affects all Honda vehicles
Yup, but the real problem here is the chosen re-synchronization strategy of the Rolling code when de-sync occurs (performed by the BCM/vehicle) that is done in backward. This is described in the article, but most of the comments here seem not to read the details.

Also Honda does offer bidirectional fobs, that make this attacks a lot harder (still not impossible if the same resync strategy is used)

wallaBBB··on Rolling-PWN vulnerability affects all Honda vehicles
That would be hard-coded on the vehicle side, but this looks more like a simply signal jammer that is described in this attack. They simple jam the RKE Lock command when you're leaving your car, you don't pay attention to the light signalization for the successful Lock and move on. They come and still anything valuable from the inside.
wallaBBB··on Rolling-PWN vulnerability affects all Honda vehicles
That one claims (without sufficient proof) that Honda does not implement rolling code in the fobs, completely opposite of this article that implies a wrong re-synchronization strategy implemented on the vehicle side.

wallaBBB··on Car Quality Is Slipping
These type of articles that do not breakdown the type of complaints are worthless. The trend of increased complaints has been present for a few years now, but when broken down the increase comes vastly from infotainment and SW related issues. And it is expected, SW complexity in the infotainment part has skyrocketed and automotive companies are in their core HW companies, not SW companies and are slow to adapt. I wouldn't consider infotainment complaints to be a sign of drop in reliability.

How to further increase the costs of medicine... Issue should be addressed at the source, this idea sounds as good as arming teachers to make schools safer.

Still an interesting idea that could be used somewhere else.

Generally OK, but I'm not sure if we should have different perspective for SpaceX considering it's funded by taxpayers' money, it's not out there competing in the free market...

wallaBBB··on Ask HN: Do people want a LinkedIn alternative?
Hmm that's tricky, you have to keep in mind that with $100 per year you're maybe limiting entry in markets with a lot of resources (e.g. IT professionals in India).

Maybe I'm wrong, dunno about price points, I do know I find it quite easy to support someone on Patreon with $5 per month if I find the content valuable. And this should not be viewed as more valuable, people are not constantly looking to switch jobs or take on more work, for many it would be pretty passive network (as is LinkedIn).

wallaBBB··on Ask HN: Do people want a LinkedIn alternative?
Sure, I paid for LI premium to check out courses (1 trial + 1 to finish) but did not find added value worth the money. Same way I pay on patreon for content I get for free anyways, to support spam-less quality content. 1-5 USD per month is a range many would pay to have a clean professional environment, and it would eliminate bots.

Problem (that I see) is getting something like that off the ground, to reach critical mass.

Also if it goes public, would it remain like that without further pressure to bring more income. Courses do sound like a quality idea from Linkedin, but other (MOOC) platforms seem to be doing it better. Perhaps a partnership with a MOOC platform...

wallaBBB··on Ask HN: Do people want a LinkedIn alternative?
It's a self-CEOs and HR circle jerk platform. An alternative would have to depart from trying to create same type of engagement as FB or Twitter, as it would run down the same path, but focus on showcasing skills and providing better search options.

hmmm, but I'm still afraid that a push for monetization and YOY growth would eventually ruin whatever good is made.

wallaBBB··on The Race to Zero Defects in Auto ICs
What these demands are driving up are End Of Line tests performed by the semi companies, and more time you spend on verification the bigger the price of manufacturing. That's why you can find basically same ICs on DigiKey or Mouser with the only difference being that one is automotive certified and a few magnitudes more expensive.

ToF + RSSI combination on keys is still to be beaten with good protocol. I say with good protocol since "ghost peak" vulnerability is really a protocol issue, but keys don't fall under CCC, and have proprietary ones.
