# FreeRTOS Kernel Teardown!! Working on porting the FreeRTOS kernel from scratch on a new target. Got the scheduler to kick off and switch between two tasks. It later runs into a crash... I am debugging that at the moment. I am going to dive into the details of... show more

@pyjamabrah Eu estou interessado em adquirir o seu curso mas eu vi lá que é válido por 365 dias quer dizer que se eu comprar agora eu só posso ter acesso por 365 dias não é acesso vitalício

Yes. I pay for the servers on monthly basis. At the moment, i have enough finances to promise 1 year access. As the finances become better, the validity can be revised. At the moment, 365 day access only :)

I personally like to understanding things from scratch. Libraries and Frameworks are hard for me to live with (until I understand how they work internally). FreeRTOS is very commonly used in the Embedded World as the goto OS. I decided to understand how the internals work and currently recording my understanding as part of a course. I focus on Porting FreeRTOS Kernel to a new target from scratch. More details here - Here is a Preview Lecture - including the Kernel files and resolving errors as we run into them... Full list of lectures recorded till now (I'll add more in a week): -- What and Why FreeRTOS -- Demo walkthrough - End goal and Tools -- Codespace Setup -- Programmers model and Essentials of ARM M CPU -- Demo - Booting the CPU -- Jumping from Assembly code to function in C files -- Fixing the problem of function calls in C -- Getting the FreeRTOS source code and documentation -- Starting to Integrate the FreeRTOS-Kernel -- Finding and fixing the portmacro.h errors -- Finding and adding the FreeRTOSConfig.h -- Enabling heap for dynamic memory allocation -- Setting the Scheduling Rate -- Getting the Kernel to compile successfully more lectures being recorded...

The time it taken for a files app to open without spiking the cpu or spinning the fan crazy. cold start (nautilus). see how windows cannot do this without glitching? and im on balanced profiler not even the low latency kernel or performance scheduler.

I don't know what's happening, but it appears that there is a memory leak inside the FreeBSD kernel. It can be triggered by dragging a window to the top of the screen.

Just got access to wabi. In the running for most beautiful product of the year. It lets me spin up tools from the apps I already use. Created a calendar invite scheduler from my Google cal instantly. This makes a ton of sense.

Geometry of Machine Learning Models - Gaussian Process Kernel In 1948 Norbert Wiener framed prediction as a correlation problem, and in the 1970s George Wahba clarified that picking a smoothness preference is the same as picking a kernel. The motivation is that whenever data i s sparse and noisy, you don't just want a fit, you want a fit with calibrated uncertainty.

lando: “this [improvement] is nothing that's going to happen overnight or in one week or two weeks' time. the gap was 50? almost a second lap off. some of that is still understanding the pu. some of it is just a better car. i think ferrari, from what we see quite clearly, have the best car. their cornering speeds are unbelievable. so for us to match that is zero chance at the minute, and we have to work very hard to understand things and learn as much as we can from this part of the season, because this part of the season now, sets up the rest of it basically. so the more we can learn, the more we can understand, the better it will be at the end of the season. but yeah, it's looking like it's going to be a long one, a tough one, but i was happy with p5 today”

I’m worried that the US government debt problem will get so bad that the US will “go broke” and I believe that there are steps we can take to prevent it. I am in the process of completing a comprehensive study about the mechanics of how countries go broke, where the US government is in its Big Debt Cycle, and what policymakers and investors should do about it. The study will be published later this year as a new book: How Countries Go Broke: Principles for Navigating the Big Debt Cycle, Where We Are Headed, and What We Should Do. As with my prior books, I am going to pass along parts of it for free as I am writing, and I'd like to discuss what it says with you and others on social media. You can read Part One here:

Ha! I notice the Trump campaign did not include the rest of the segment, in which I explained how Trump had “taken a kernel of truth and spun it into something not even resembling reality anymore.” Here’s part one.

Linux is the most widespread operating system, globally – but how is it built? Few people are better to answer this than Greg Kroah-Hartman (Greg K-H): Greg has been a Linux kernel maintainer for 25 years, and one of the 3 Linux Kernel Foundation Fellows (the other two are Linus Torvalds and Shuah Khan). Greg manages the Linux kernel’s stable releases, and is a maintainer of multiple kernel subsystems. We cover the inner workings of Linux kernel development, exploring everything from how changes get implemented to why its community-driven approach produces such reliable software. Greg shares insights about the kernel's unique trust model and makes a case for why engineers should contribute to open-source projects. Watch or listen: • YouTube: • Spotify: • Apple: Brought to you buy: • WorkOS — The modern identity platform for B2B SaaS. • Vanta — Automate compliance and simplify security with Vanta. Check out all of our current sponsor and their offerings: ---- One of the most surprising things I learned about Linux: although 4,000 developers contribute to the project from 500 companies per year, and has around 800 kernel maintainers, the project is run with email, git... and that's about it! No dedicated project managers, no regular meetings across the group. It's a truly fascinating and unique model (and only applies to the Linux kernel project: not to Linux distributions.) We go into more detail about this topic with Greg in the podcast as well.

I am outside Rabasotho Community Centre in Tembisa listening to the frustrations of residents. It is clear that there is a breakdown of communication between the city and residents, something that needs to be arrested as a matter of urgency.

Thodōros Angelopoulos on his film language & the reason for not liking some of Andrei Tarkovsky's movies: "Interviewer: The most important thing in your films seems to be the consistence of every single shot. It has to have its own force and build up its intensity as it goes. Angelopoulos: It is for this reason that my personal film language is based on expanding the dimension of time. Before you enter into the gist of any given shot, you have to be given the time to find out the relations between the actor and the landscape. For this reason, I love Tarkovsky's 'Stalker' (1979); 'Nostalghia' (1983), I like less; 'The Sacrifice' (1986), I do not like at all. As far as I am concerned, the Holy Trinity-that of the actor, the landscape, and the camera-is perfect in Stalker. Interviewer: In most of your films, there seems to be a sense of melancholy for the past. But the two children, who are not subject to this melancholy, are pulling you in a different direction. Angelopoulos: I believe the past is my own personal past dragged into the present by my occupation as a filmmaker. The tree at the end of 'Landscape in the Mist' (1988) is the tree from 'Voyage to Cythera' (1984), a reference to my own personal film Landscape. In the course of this picture, the children cross a film landscape in order to reach, at the end, a different film landscape, which, I believe, should offer them renewed hope. I would like to believe the world will be saved by the cinema. Cinema is my world and it is the scope of all my journeys. I am always searching for secret little utopias that will enchant me; I am doing my best to believe in the relevance of these trips I am constantly embarking on through my films." (Thodōros Angelopoulos's interview with Serge Toubiana & Frederic Strauss, 1988) P.S: Remembering the great Greek filmmaker Thodōros Angelopoulos on his 91st birthday.

A LINUX KERNEL DEVELOPER PROVED THE THING YOU PUSH CODE TO IS SECRETLY A DATABASE THAT CAN VERSION ALMOST ANYTHING AND THAT MOST DEVS HAVE ONLY EVER TOUCHED A TENTH OF IT 42 minutes from Josh Triplett -- a longtime Linux kernel and Debian developer -- showing that Git is a general-purpose, tamper-evident versioning engine that just happens to be famous for code. -> The moment it clicks, Git stops being "Where my code lives" and becomes what it really is underneath: a content-addressable store that can version almost anything -- your configs, your notes, your servers' state, entire datasets. People run whole wikis on it. They version their entire machine's configuration with it. They ship websites by pushing to it. They track data too big to email. None of it is a hack -- it's the same handful of objects you already use for code, pointed somewhere new. Treating Git as a code-only tool was never the ceiling -> it's a versioning engine for anything, and the people who see that automate what the rest of the team still does by hand. And as AI agents start spitting out not just code but configs, docs and data, the one system that can version and audit all of it at once is already sitting on your machine. You learned five commands to survive. This is the talk that shows you were standing on top of a database the whole time. It changes what you think the tool is even for. Bookmark & Watch it today ↓
