It describes the MMC storage device driver functionality in Linux Kernel and it's role. It explains different type of storage devices available and how they are handled from MMC driver point of view. It describes eMMC (internal storage) device and SD (external storage) devices in details and SD protocol used for communicating with these devices in Linux.
This lecture discusses the concept of Multi-User support in Linux. It discusses how Linux protects user files and resources from other user unauthorized access. It also shows how to share resources and files among users, how to add/del users and groups.

Case study of BtrFS: A fault tolerant File systemKumar Amit Mehta
A case study of Fault Tolerance features of BTRFS. These slides were prepared for the coursework for a Masters level program at Tallinn University of Technology, Estonia. A lot of materials in the slides are taken from the materials in the public domain. Many thanks to the people on BTRFS IRC Channel.
A basic introduction to the philosophy behind and internals of linux based operating system distributions, meant to be presented by someone who knows this stuff rather that as a DIY thing.
Sadly, I seem to have lost the sources for this after my hard drive crashed.
Btrfs: Design, Implementation and the Current StatusLukáš Czerner
Historically Linux has always had quite decent pool of local file systems in the tree. However only one of them has been usually considered as a "General purpose local file system". Extended file system was the one. Now it is about to change as btrfs "B-tree file system" joined the crew. In this talk I would like to give a brief overview on the design and implementation of btrfs and highlight some if its strong and weak qualities. We might even try to peek into the future to see what the future of btrfs might look like, what might be its main use case, if it will leave all other file system behind, or silently die after the hype fade away. Finally, I will introduce you to the current state of development. I'll try to summarize what has been done so far and what you can use today. And of course, highlight features which are either ready or are about to be ready for users to appreciate. Some examples of btrfs usage might follow
It is the File system that is contained on the same partition on which the "Root directory" is located. It is the File system on which all the other file systems are mounted
In this PowerPoint, learn how a security policy can be your first line of defense. Servers running AIX and other operating systems are frequent targets of cyberattacks, according to the Data Breach Investigations Report. From DoS attacks to malware, attackers have a variety of strategies at their disposal. Having a security policy in place makes it easier to ensure you have appropriate controls in place to protect mission-critical data.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
