The temperature this morning was a balmy 22 C / 72 F.
Come to sunny Israel!

My mother went to Israel in the 80's with a few friends. She really enjoyed it. She was trying to learn Hebrew at the time, I think. She had befriended an elderly lady at the time who was an Holocaust survivor, and through there discussions and hanging out, my mother felt compelled to visit Israel.
I actually would like to visit Israel and surrounding countries sometime. Not sure if it will happen anytime soon, but I would like to.
As a side note: My in-laws visited Israel about 10 years ago or so with their church group, and were escorted off a bus at a checkpoint by soldiers with machine guns because it was "not safe" for tourists to be traveling that route at that time. Yikes!!

We did a similar trip in 2019, but we were allowed into the West Bank (the 'safer' sections). The army only checked us on the way back into Israel proper.

It could have been an army drill (Israel is quite small - about the size of New Jersey), so they closed off the downrange area. If they had a local tour guide, in addition to the pastor who lead the group, he/she was remiss in not checking for this sort of thing before choosing the day's route.

I grew up inland in Norway, where the winter air was super dry, like outdoors RH down to 20% (everyone had humidifiers in their homes to prevent wood from drying out so much that it would crack up), and no wind at all - we used to joke that if the aspen leaves are moving, the local newspaper will make a story about the storm. (For those of you unfamiliar with aspen: The tremble all the time, even when the wind is so weak that you hardly will notice it at all.) We had no idea what 'wind chill factor' was about when it was included in the weather forecasts.
We didn't consider it 'real winter' until the temperature fell below -20°C. In school, we where kicked outdoors in the breaks between lessons, to get some fresh air. The limit for being allowed to stay indoors was at -20°C outdoor temperature.
Nowadays, I live by a fjord. The air is a lot more humid; 0°C is a lot colder than -20°C where I grew up. If we also have a 10 m/s wind, the frost is unbearable, even with only a couple degrees below zero.
Yet, I still think of 'wind chill' primarily as an argument in a "Mine is bigger than yours!" quarrel. It certainly is essential to the effect on the bare skin you expose outdoors. It is completely irrelevant to any mechanical device (such as starting your car, or the low-temperature battery capacity loss of your electric car). If it marginally affects the required heating of your house, then the insulation is far too poor. (At least by Norwegian standards - our houses are extremely well insulated.) When someone refers to the wind chill adjusted temperature only, my immediate thought is 'Oh well, so you want to sound impressive. Fair enough, but maybe I am not that impressed, especially if you are not talking about being out walking in the wind."

I sympathize. I had to go to an *OUTDOOR" wedding yesterday, with temp around 72F , descending to mid 50s by dusk. After living 30 years in Alaska, I just about froze my tookus off

A team that can make a bubble that lasts a year could be incredibly valuable in extending the life-span of MS bubbles, like the latest previews of Maui, that never work, and now barely last a few months: [^].
A leaked document suggests the French demands for not having Windows 11 installed, and, for a permanent guarantee that only the appellation "Les Bubble" will be used are being discussed ... the demand no Happy Meals will be sold on the Lille campus is meeting strong resistance at MS.
Another purported internal memo records a senior MS executive's opinion: "Compared to Activsion, we should be able to get this one for chump change."

I`m trying to get an impression/idea about how complex software found in cars can get.
To start with there was a scandal a couple years ago that had at its heart the issue of a car producer making the software in charge with reading `exhaust quality` display false results. That got me wandering what`s the point of having such a piece of software on board of each car. To my mind all engines found inside same model cars produce exhaust in the same amount and of the same (chemical) formula if subjected to identical conditions.
I`m curious about this exhaust reading software. My guess is that it`s sensors recording the gas formula but are the sensors always on, like does the driver get a real time display of the recoded result as he is driving the car?
Also my sister has a car that has a digital display (LCD screen) of the speedometer and all the other information that is usually displayed through analog methods/indicators. The car has also a display that shows what is recorded by the car front and rear cameras. Then there is the radio and music information that is displayed digitally as well. My question is there a centralized operation system behind that manages all of it?
Then there is of course the question of Tesla cars which have an even higher number of sensors and higher complexity in the way the sensors operate.

There are many processors in modern cars from little uControllers to "proper" CPUs. The infotainment system is just one of them - and that one can be quite spectacularly powerful. For example, the Hyperscreen in the Mercedes EQS uses 8 CPU cores and 24GB RAM (which is more than my desktop PC has!)
This may help you understand just how much processing is going on: Adventures in Automotive Networks

One car coming out of the line today might have some million lines of source code working inside.
They have (depending on the manufacturer and the model) up to 150 controllers. The new E³ architechture brings the HPDC Controllers (5 to 7 units) and those are really powerful.
CalinNegru wrote: My question is there a centralized operation system behind that manages all of it?
The system is a tree, there are several communication bus and in each of them there is a master coordinating everything and communicating with other masters. Each Master has a group of subordinates, some are slaves some are independant cpus that just are in the same communication segment.
Up to now the highest CPU in the "hierarchy" was the Gateway, in the new E³ it will be the HPDC-1. Although I think that everyone is equally important, because nothing works without every one working fine.
In the past, you could get a screw driver and fix some things, current cars... forget it. You need not only a PC, you need software, connection to restricted systems and the knowledge to not do more harm than anything.

That "exhaust quality display" was far more than just the display. The car detected when it was on a dynameter and actually changed the engine and emissions tuning to pass the emissions tailpipe test.

The answer to your question is automotive software is generally incredibly complex and poorly structured. NASA's full report on the Toyota unintended acceleration in the 2000s slammed Toyota for such poor software design and architecture that they (NASA's software engineers) couldn't say for certainty that Toyota's software wasn't causing unintended accelerations.
In addition, it appears automakers have used techniques out of the 60s for their control software. Techniques such as timing loops that can't be ported to newer, faster hardware; no abstraction of hardware layers; etc. This became apparent last year when the CEO of Intel Corp. chastised the auto industry for wanting the integrated circuit industry to reopen foundries for 20 year old chip technology. Tesla and other EV startups appear to have avoided this issue by using modern software design techniques so that when one chip became hard to get they were able to switch to other chips to continue manufacturing.

Amen.
Probably the best-designed part of the software is the entertainment deck, which typically runs Android.
The actual control software for the car is a cluster-![Elephant | [mastadon]](https://codeproject.freetls.fastly.net/script/Forums/Images/elephant.gif)

Things evolved. Mostly from 2005 onwards, thanks to self promoted commitees like GENIVI and the ISO26262 regulations. AutoSAR also added some layer of standardization, though its drawbacks are heavy and I can't speak openly of them.

It's a half hoax. Model based design has a single software suite on the market produced by a monopolits company whose name starts with Math and ends with Works. They overcharge their licenses and the courses (3 day lesson for 2 people is over 25k€) and it can elegantly abstract the control parts of the vehicle (PI control, retroaction loops) but not the application part (i.e. diagnostic protocols like UDS and customer dependent behaviors) and definitely not the hardware part - all the drivers are supplied by the manifacturer but the HAL must be written manually to ensure compatibility with the model. And the generated code is significantly bigger and slower, which is an issue in a market where most ECUs are 40 Mhz processors with 64kB of flash memory and 3 to 6 kB of RAM.
Tesla and other EV startups are marketing towards very high prices anyway so they will use more integrated (and proprietary) logic with more powerful ECUs... with the underlying issue that ECUs are active even when the car is off, and more powerful logic consumes more power than less powerful logic.

Mosti automotive components must work from -40°C to 155°C, they must be EMI compliant and automotive safe. They have to be validated (and automotive validation is second only to biomedical as for anal retentiveness) and certified as safe. Many manifacturers will prefer something that works for sure rather than something shinier, better, bigger that kills a dozen people. Wether you're driving an EV or an ICE, you're placing your ass on what's essentially a bomb with a carefully controlled energy dispersion. Don't mess with that control.

I did a little research - SpaceX uses three dual core x86 processors in the Falcon 9. These off the shelf processors handle radiation (via redundancy) and temperature swings from -150C to +150C. The legacy automotive industry is in serious denial about modern processors.
