You think you're not a target? A tale of three developers...
If you develop or distribute software of any kind, you are vulnerable to whole categories of attacks upon yourself or your loved ones. This includes blackmail, extortion or "just" simple malware injection… By targeting software developers such as yourself, malicious actors, including nefarious governments, can infect and attack thousands — if not millions — of end users. How can we avert this? The idea behind "reproducible" builds is to allow verification that no flaws have been introduced during build processes; this prevents against the installation of backdoor- introducing malware on developers' machines, ensuring attempts at extortion and other forms of subterfuge are quickly uncovered and thus ultimately futile. Through a story of three different developers, this talk will engage you on this growing threat to you and how it affects everyone involved in the production lifecycle of software development, as well as how reproducible builds can help prevent against it.

Bootcamp linux commands
Linux is an open-source operating system created by Linus Torvalds. It is widely used for servers, personal workstations, and other applications. The Linux kernel allows the operating system to be customized for different user needs. Common Linux commands allow users to interact with files and directories to perform functions like copying, moving, deleting, and more through options like ls, cp, mv, rm, and others. Help pages provide documentation on commands through the man command. Permissions control who can access and modify files using commands like chmod. Other useful commands include grep, ssh, scp, and more.
Linux Directory Structure
The Linux directory structure is organized with / as the root directory. Key directories include /bin and /sbin for essential system binaries, /boot for boot files, /dev for device files, /etc for configuration files, /home for user home directories, /lib for shared libraries, /media and /mnt for mounting removable media, /opt for optional application software, /proc for process information, /root for the root user's home, /tmp for temporary files, /usr for secondary hierarchy data and binaries, and /var for variable data.
Linux files and file permission
This document discusses Linux file permissions. It explains that each file belongs to a user and group, and access is controlled by permissions for the user, group and others. It then covers the chmod command for modifying permissions, showing examples of using numbers, letters, and operators to set read, write and execute permissions for users, groups and others. The document also introduces the chown and chgrp commands for changing a file's owner and group.
File permissions
Most file systems have methods to assign permissions or access rights to specific users and groups of users.
These system control the ability of the users to view, change, navigate, and execute the contents of the file system.
Permissions on the linux- systems are managed in three distinct scopes or classes. Theses scopes are known as users, groups or others.
Lecture1 2 intro-unix
The document provides an overview of command line basics, including X Windows, consoles and terminals, UNIX commands, the UNIX filesystem, and the vi editor. It describes the anatomy of commands, getting help with man pages, basic account and file management commands, viewing and editing files, and installing applications. It emphasizes that the command line is always available and more efficient than GUIs.
File permission in linux
This document discusses basic file permissions in Linux/Unix. It covers the different file attributes seen in the ls -l command output including permissions, owner, group, size and date. It describes the rwx permissions for owner, group and others. It also explains how to modify permissions using chmod with absolute and symbolic modes, and how to change file ownership with chown.
Unix files
Files are the building blocks of the UNIX operating system. There are different types of files like regular files, directories, FIFO files, character device files, and block device files. The UNIX kernel uses files, file descriptors, a file table, and an inode table to manage file input/output operations when a user executes a command. This allows processes to open, read, write, and close files.

File directory definition 54(2)
A directory is a file that contains entries with information about other files in the system, including the file name, type, size, owner, protection, usage count, times of creation and last modification, and list of disk blocks used. A file system organizes storage across partitions, with each partition containing a directory of its files. Partitions are known as minidisks in IBM systems and volumes in PCs and Macs. Each directory records information about all files in its partition.

Linux Presentation
This document provides an overview of the Linux operating system. It discusses that Linux is an open-source operating system that provides a structured file system, multi-user capabilities, and strong security. It describes the Linux file structure with directories like /bin, /boot, /dev, /etc, and explains commands to view processes, manage users and files, and install packages. Network services like Apache web server, OpenSSH, and FTP are also summarized.
Management file and directory in linux
In many ways, directories are treated like files. They can be created, deleted, moved and copied from Nautilus or from a shell prompt, using commands similar to those for files.
Creating Directories
You must have write permissions in a directory in order to create a new sub-directory. Most users have these permissions in their home directory (and its sub-directories) and the /tmp/ directory.
To create a new directory with Nautilus, navigate to the location of your new directory. Right-click in a blank portion of the window and select Create Folder. A new folder icon appears with the highlighted text untitled folder. Type a name for your folder and press [Enter].
To create a new directory using a shell prompt, use the command mkdir. Enter: mkdir <directory-name>, replacing <directory-name> with the intended title of the new directory.
Deleting Directories
To delete a directory from Nautilus, right click on it and choose Move to Trash, or click and drag the icon to the Trash on the Desktop.
To delete an empty directory from a shell prompt, enter the command rmdir. To delete a directory that may not be empty (and consequently everything inside that directory), enter the command rm -rf <directory>. Refer to Section 4.5.5 Delete files with rm for more information regarding the rm command.
Dot Directories
Applications create "dot" directories as well as dot files. Dot files are a single hidden configuration file — a dot directory is a hidden directory of configuration and other files required by the application. The non-configuration files in these directories are generally user-specific, and will be available only to the user who installed them.

Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.
