Check out Asahi Linux, they run on Apple Silicon and have translation for 32 and 64 bit x86, so they even go further than what Rosetta achieved. Open Source as well.


A very interesting read.

The article states that they added a computational correction step which is run whenever a result might be incorrect but skip it most of the time.

I am wondering whether this might cause problems for small real-time systems that do not have an FPU. If the runtime cost of an operation depends on the input, it is very hard to figure out whether deadlines can be met in all operation conditions.


It is likely also a timing side channel (can be a security problem).


Great post, the fusion of scale with unit is a mess.

When using it as a factor, for example when describing attenuation or amplification it is fine and can be used similar to percent. Though the author is right - it would be even more elegant to use scientific notation like 1e-4 in this case.

For using it as a unit it would really help to have a common notation for the reference quantity (e.g. 1mW).

But I guess there is no way to change it now that they are established since decades in the way the author describes.


Scientific notation would be worse, because you can't add them to get the combined gain. That's where dB's really shine.


While this gives an impressive boost in performance, it also means that frametimes are around 10% longer when the status bar has to be updated.

Overall this can mean that in some situations the game feels not as smooth as before due to these variations.

Essentially when considering real time rendering the slowest path is the most critical to optimize.


Yep, in a real situation the player would be constantly moving around collecting hp/ammo/weapon, losing health/ammo to monsters... all these would cause the status bar to be frequently updated.

I don't think the benchmark accounts that.


Nordic semiconductor also has microcontrollers with BT and Wifi. They are much less common than espressifs solution though.


Fyi, while Nordic products are usually excellent, they did not design the wifi ics. They bought a company and slapped their name on the chips. I haven't used them yet, but from what I've heard they don't live up to Nordic's standard.

Edit: also afaik they don't have a mcu+wifi in one yet.


Because the prices are not competitive enough for hobbyists. How can you expect people to adopt and develop on top of your chips if they can't afford it?


BT/Wifi on a single chip? Do you have a part number?

That'd be revolutionary.

I love the ESP32. But they love (too much) current.


https://www.nordicsemi.com/Products/Wireless/WiFi/Products?l...

Search for the SiPs and SoCs, they all support BLE.


But these solutions require two chips, one for bluetooth and one for wifi where the ESP32 does it all in one.


Ah yes, you're right, I misunderstood their page.


Though this is an artificial constraint imposed by the platform holders (i.e. Apple and Google).

Once they figured out how their new AI assistant needs to look like their own rules for 3rd party apps won’t matter anymore.


It’s also a constraint imposed by a number of states with two-party consent recording laws.


This doesn't make any sense. If that were the case, why don't video recorders have these limitations?


I could see that in the coming years the value of Waymo for Google is not actually in collecting revenue from transportation fees but to collect multi modal data to feed into its models.

The amount of data that is collected by these cars is massive.


You are right it feels off.

The position of the guitar in stereo is all over the place, higher frequency elements appear to come from the left while other parts are more centered.


At the same time France had to buy loads of electricity from Germany in the last year because several nuclear plants had to shut down due to a) maintenance problems and b) low rivers that could not provide sufficient cooling.


Ironically, I hear the ones that were shut down in Germany were some of the best maintained in the world and had very high "capacity factors" even when compared with other nuclear (fraction of time delivering power to the grid). It seems like the solution to poor maintenance is better maintenance? Some of the causes of recent poor French maintenance are analyzed here: https://player.fm/series/decouple/somethings-rotten-with-fre...

I assume you wouldn't seriously argue that rivers are the limiting factor to deployment of nuclear energy.


It's not that ironic.

Germans tend to do stuff right when they do it.

The ironic thing to me is that Germany is so anti-nuclear.


Being “anti nuclear” made a lot of sense until a madman decided to attack Ukraine.

And with the world economy stabilizing after that mad man’s actions it’s again making a lot of sense as nuclear continues to be far more expensive than other renewable alternatives.


It's cheaper to run your 30 year old, perfectly fine, perfectly safe, well-functioning nuclear plant than to build and run a new natural gas plant - which is what Germany decided to do.

Berlin Brandenburg Airport enters the chat


And sometimes it's the opposite https://www.worldstopexports.com/electricity-exports-country...

True France's infrastructure is not resilient enough on climate, they are also a bit in denial over that. Everyone have their weaknesses.


You also pay for quality control. Cheaper brands often have decent audio quality on average but high variation in between individual pairs of headphones. They also tend to fall apart after 1-2 years of use in my experience.
