A database management system (DBMS) is introduced as a collection of programs that enables users to create and maintain a database by defining, constructing, manipulating, and sharing the data. A DBMS also protects the database and maintains it over time. Examples of database systems that store student and course information are provided to illustrate database concepts. Characteristics of the DBMS approach are compared to the traditional file system approach.
Lesson 3.2
A flowchart is a graphical representation of a process or system. This document provides flowcharts for troubleshooting various hardware issues, including hard drive boot problems, CPU/RAM/motherboard performance issues, video adapter/GPU/monitor problems, peripheral device failures, SCSI/SAS drive errors, and DVD/CD/Blu-ray recording issues. The flowcharts help diagnose common problems and their potential solutions.
Lesson 3.1
This document discusses common computer errors, including hardware errors like blank monitors, hard drive failures, and faulty keyboards or mice. It also covers software errors such as access denied, file not found, and out of memory issues. Specific error types like disk read errors, boot failures, freezing, and the blue screen of death are explained in more detail. The document emphasizes the importance of properly diagnosing errors to identify whether the issue is hardware or software related.
Lesson 1.6
Bootable media contains software that allows a computer to boot from a removable device like a USB flash drive. When booting, the computer performs self-checks, loads the BIOS which finds the boot loader on the hard drive, and then loads the operating system along with hardware drivers and any startup programs. Bootable USB flash drives provide an easy way to install operating systems without discs by creating a portable boot device.
Lesson 3.2
Computer troubleshooting is a systematic process used to locate the cause of faults in computer systems and resolve hardware and software issues. It involves following a logical process with steps like identifying the problem, establishing a probable cause, testing theories to determine the cause, developing a solution plan, verifying the system works, and documenting findings. Troubleshooting skills are developed over time through experience solving different problems. Common computer issues include failures of storage devices, motherboards, power supplies, CPUs, memory, displays, and more. Solutions may involve checking connections, updating drivers or BIOS, replacing faulty components, and ensuring proper cooling and power.

Modelling Up - DDDEurope 2024 - Amsterdam
What to do when you have a perfect model for your software but you are constrained by an imperfect business model?
This talk explores the challenges of bringing modelling rigour to the business and strategy levels, and talking to your non-technical counterparts in the process.
Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

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.
