software defined vehicles

 https://youtu.be/hJe5xQr4LEY

This is a podcast by Motor Trend about the future of car. The host is talking about software defined vehicles [SDV] and is joined by Jeff Chow, the co-founder and CEO of Sonatus and Robert Day, the director of goto Market of Automotive goto Market vehicles at Arm.

Sonatus is a company that supplies advanced software for vehicles and the cloud. Arm on the other hand is a company that manufactures computer chips.

The conversation starts with a question from a viewer named DOD Mac who asks if a person can rip out the battery and motors from a Porsche Taycan and put them into a new VW ID7 in order to make it faster. The host says that this might be difficult because the software might not be compatible.

The conversation then goes on to discuss the future of software defined vehicles. Jeff Chow says that in the future, cars will have fewer physical buttons and more software-based controls. This will allow for more customization and features. Robert Day from Arm agrees and says that cars will need more powerful processors to handle all of the data that will be coming from the various sensors in the car.

One of the challenges of software defined vehicles is that it will require a lot of collaboration between different companies. The companies are working together to develop standards and practices for developing and deploying software in cars.

The podcast concludes with a discussion about the economics of EVs. The host says that EVs are becoming more affordable and that he believes they will eventually become the dominant type of car.

the science of thinking

 https://youtu.be/UBVV8pch1dM?si=tr6GH8NxsDYegwRi

This video talks about how our brains think and why we sometimes make mistakes. The video introduces two characters, System 1 and System 2, to illustrate two different thinking modes.

System 1 is called Gun. It is fast, automatic, and effortless. It makes most of our decisions without us even realizing it. For example, when you read a sentence, Gun automatically fills in the gaps and corrects any errors so that you can understand the meaning.

System 2 is called Drew. It is slow, deliberate, and effortful. It is responsible for complex thinking and reasoning. For example, solving a math problem or making a difficult decision requires Drew's involvement.

The video argues that most of the time, our brains rely on Gun for thinking, which is why we sometimes make mistakes. Gun makes decisions based on shortcuts and heuristics, which can lead to errors. For example, the video mentions a common trick question: a bat and a ball cost $1.10 together, and the bat costs $1 more than the ball. What does the ball cost? Most people will blurt out 10 cents, but the correct answer is 5 cents. Gun jumps to the answer without carefully considering all the information.

The video also explains that Drew is lazy and doesn't like to work hard. So how can we get Drew to work harder? The video suggests a few ways, such as making things difficult to understand. For example, presenting information in a confusing way or using a difficult-to-read font can force Drew to pay more attention and think more carefully. This can lead to better learning and fewer mistakes.

Overall, the video highlights the importance of both Gun and Drew in our thinking process. While Gun's fast and automatic thinking is essential for many everyday tasks, Drew's slow and deliberate thinking is necessary for complex problem-solving and avoiding mistakes.

S. anginosus could also act as a biomarker to show that the patient was at high risk of cancer or required close monitoring, which was important for early diagnosis and prevention.

He said the bacteria was often found in people's mouth and teeth, so maintaining oral hygiene could prevent the emergence of the bacteria and gastric cancer.

"People with periodontitis or dental calculus may carry this bacteria, which may be ingested into the stomach through saliva and lead to other conditions," he said.

Why the secret to success is setting the right goals

" În România e un pic altă treabă și nu are de aface mult cu infrastructura - poți găsi explicații și scuze în frustrări și în faptul că în România concurezi mereu cu ceilalți pentru ceva , cine ajunge primul, sau ultimul la muncă, la mare, la restaurant la pula mea. Este mindsetul ăsta. 

Iar asta generează comportamente deviante, mână în mână cu sărăcia, lipsa de educație și faptul că nu există costuri administrative serioase. Nu tăiat de mâini ca la arabi , sau știu eu ce. Bani, că banii ne dor, supraveghere mai atentă, fie și automată ( dar în România au anulat prin lege , excepție de constituționalitate ceva , posibilitatea de a avea camere de viteză - in felul defect în care fuseseră implementate ) și decăderea din drepturi până la dovada îndreptării si reeducării. În loc de șpagă, de exemplu. 

Iar comportamentele deviante sunt de tipul - te trezești cu oameni care văd ( cred eu că văd, ar putea fi total retardați) că nu au unde să depășească , că o să intre frontal în tine și totuși se bagă a la chicken game, că o să frânezi tu , pariind in primul rând pe faptul că ești atent la ce fac ei. Oameni care se aruncă în depășiri fără niciun fel de vizibilitate pariind viața lor și pe a ta pe norocul de a nu se întâmplă nimic. Oameni care intra pe interzis și dacă te întâlnești cu ei manifestă tupeu să te dea pe tine la o parte dacă se poate.  Astea nu-s pentru că n-au autostrăzi și pentru că sunt camioanele lente, ci pentru că sunt săraci, needucați, probabil trăiesc rău / greu și pun un preț foarte mic pe viața lor, anume trăiesc ca și când nu ar avea nimic de pierdut. Cei mai mulți au, de fapt, dar e un mindset Românesc - ține de competitivitate și sălbăticie, să te prefaci că nu ai nimic de pierdut, până pierzi. Și după aia te vaiți și cauți vinovați - sistemul, drumurile, normal. 

Și eu circul tot în România, tot pe drumurile ălea, tot cu oamenii ăia , și pe mine mă deranjează , evident aglomerația și statul pe loc și cu toate astea, am  trecut prin și de nivelul ăla unde comportamentul meu trebuie scuzat de lipsa infrastructurii și în general ceilalți. "

G12evo replaces G13 and G12+

 G12++ = glycol + Si HOAT

G13 = gycerol + Si HOAT
G12evo = glycol + PSi HOAT
Apparently phosphate HOAT was common in the Japanese vehicles, while silicate HOAT was common in the German vehicles, back when HOAT got rolling.


If you do go looking at third-party fluids for whatever reason, color means little to jack. Go by the TL standard:
...
TL774 F - G12+
TL774 G - G12++
TL774 J - G13
TL774 L - G12evo

difference between initrd and vmlinuz

 vmlinuz files contain the Linux kernel proper.

initrd files are CPIO images, filesystem images.

The boot loader is responsible for loading both the kernel image and the initrd image into memory. They both will be in memory, before the boot loader hands control over to the kernel.

The kernel will receive the address where the initrd is in memory; it will just "interpret" it as if it were a full filesystem, in RAM. (The kernel does actually decompress it first. CPIO is used, because it is simple and robust to implement, requires not too much code, and has all the features needed.)

You can extract an initrd image into current directory using

Code:

zcat /boot/initrd... | cpio -i

You can generate an image from the contents of the current directory and all subdirectories using

Code:

find . | cpio -o | gzip -c > /tmp/new-initrd

The image must be somewhere other than the current directory or any subdirectories, because otherwise cpio may include a partial copy of itself.

An initrd image will contain a script (or program) called /init (I keep the / in front to highlight that it will be in the root directory of the initrd image). That is the only real process the Linux kernel will start, whether an initrd is used or not. It will be process ID 1. If the process ever exits or crashes, kernel will panic -- but it is so rare you are unlikely to ever see that happen. (Okay, the kernel can start [worker processes], and even run /sbin/modprobe to load modules to satisfy module dependencies, I think, but they don't count. They're just slaves working on specific tasks.)

/init is almost always a POSIX shell script, so feel free to extract an image and read it in your favourite text editor. (An initrd /init will later on exec (replace itself) with the normal init, used during normal operation. If you look at your process list, you will always see process 1, named init.)

The main purpose for an initrd image is to prepare the system for the actual operating system, for example to load the modules the kernel should use. These kernel modules are included as files in the initrd image, usually in /lib/modules/kernelversion/ (again, starting from the root of the initrd image). The initrd will then also contain /sbin/modprobe and/or bin/insmod , /lib/ld-linux.so.2 ,and /lib/libc.so.6 , so that the script can load any kernel module it deems necessary.

First, however, /init will create a few additional directories, and mount the special filesystems. These include /proc, /sys, and usually also /dev (using the devtmpfs filesystem). Then, /init will parse the kernel command line, /proc/cmdline. This is the string you can set in the boot loader, defining how you want to start up your system.

It can then check files and directories in /proc, /sys, and /dev to find out which hardware is present and load the appropriate modules, but we have something much better: udev. udev is a hotplug mechanism, where the kernel tells the userspace udev daemon about all the hardware it finds, and about all hardware events later on, like when you plug in or remove something. udev configuration is ordered as rules, usually in /lib/udev/rules.d/, and it takes care of not only loading the necessary kernel modules, but also creating the necessary symlinks and all that.

It is quite possible to have a DHCP client in an initrd, and use for example NFS for all other filesystems. It is often used for thin clients. The kernel command line may then contain the NFS server name and the name for the machine itself, so it can obtain the correct filesystems. As you can see, that requires only a little thought, and a rather simple initrd, to set up and maintain. (Of course, something like this is impossible with most common proprietary operating systems.)

In Linux, resuming from a suspend-to-disk image (usually called "hibernation") is also done in the initrd. If the initrd detects a suspended image, it will resume it instead of continuing with the normal boot. In fact, there is even an utility called kexec, which can start another kernel altogether, without a full reboot (a "warm reboot").

initrd is, for all intents and purposes, a very small operating system image. It has the singular purpose of preparing the system for the actual operating system you want to use. Typically, it will mount the true root filesystem (named in the kernel command line) -- it must contain basic binaries (/bin and /sbin), libraries (/lib and possibly /lib64), and of course configuration files (/etc). Finally, the /init will replace itself with /sbin/init on the actual system, which will continue with mounting the rest of the filesystems, and starting all the services.

Many distros do require an initrd image, even if your kernel has everything built in, and does not support modules at all. In those cases, the initrd is expected to handle all of the other stuff mentioned above -- for example, starting udev, or looking for a hibernation image.

On other distros, an initrd is not needed, and the init scripts can handle the boot from raw kernel (plus root filesystem) up. For example, you can look at Linux From Scratch to see what those init scripts then have to handle.

The Linux kernel really does not care whether you have an initrd, or if your root filesystem can handle the entire init by itself. It is more of a matter of versatility and ease of management; most distributions have automatic scripts which regenerate initrds when new kernels are installed. If you use Busybox, you can pack a quite usable system into an initrd and be done with it -- many routers actually do that, with the initrd stored on a built-in flash chip.

query scale-out

 Query scale-out is a feature in Power BI Premium that allows you to distribute query processing across multiple read-only replicas of a dataset. This can significantly improve the performance of your reports, especially when you have a large number of users or when your dataset is very complex.

Here are some of the benefits of using query scale-out:

• Reduced query latency: When multiple users are querying a dataset, the replicas can share the load, which can significantly reduce the latency of each query.
• Increased throughput: With more replicas, you can handle more queries at the same time, which can improve the overall throughput of your Power BI solution.
• Improved data freshness: Refresh isolation ensures that data refresh operations do not impact query performance, so users can always see up-to-date data.
• Automated scaling: Power BI Premium can automatically scale the number of replicas based on usage, so you don't have to worry about manually adding or removing replicas.

Here are some of the limitations of using query scale-out:

• Increased storage requirements: Each replica of a dataset needs to store the entire dataset, so you will need to have enough storage space to accommodate the replicas.
• Increased network traffic: When users query a dataset, the request must be sent to all of the replicas, so there may be an increase in network traffic.
• Potential for conflicts: If multiple replicas are updating the dataset at the same time, there is a potential for conflicts. Power BI Premium uses a conflict-resolution mechanism to resolve these conflicts, but this can add some overhead.

Overall, query scale-out is a powerful feature that can significantly improve the performance of your Power BI solutions. However, it is important to weigh the benefits and limitations carefully before deciding whether or not to use it.
