1) The document discusses the increasing rate of change in software development and how that impacts producing quality software.
2) It questions whether quality is contextual and dependent on the purpose and constraints of the software.
3) Various practices are presented for coping with change and producing quality software at high rates, such as continuous integration, reducing documentation, tracking changes, user acceptance testing, and exploratory testing.
Majd Uddin has over 15 years of experience in software quality and leadership roles. He discusses the importance of effective communication when leading others. The communication process involves understanding different perspectives to find common ground. Leaders should make their messages easy to understand by avoiding jargon and considering how new ideas may be initially perceived. When proposing changes, leaders must be prepared to address concerns from team members and thoughtfully respond to questions.
On the Twin Cities Testers Meetup that happened in Islamabad, Pakistan were presented three tips to end the war of Testers and Programmers that hamper the team spirit and quality.
This document summarizes a presentation about software testing. It introduces the presenter, Majd Uddin, and his background in software testing. It then discusses that software testing is a real job, noting many open testing positions at companies like Microsoft and Google. It defines software quality as software that works well, is easy to use, secure, always available, and more. It says that both programmers and testers are needed to ensure software quality. The document outlines qualities of a good tester and leaves time for questions.
Este documento describe la neuropatía desmielinizante inflamatoria, también conocida como enfermedad de Guillain-Barré. Se trata de una enfermedad autoinmune que causa debilidad muscular y pérdida de reflejos. Existen dos tipos principales clasificados según su curso clínico: agudo o crónico. El tratamiento incluye soporte respiratorio si es necesario, así como reemplazo de plasma o inmunoglobulina intravenosa si se administran tempranamente.
1) The document provides information about booking taxis through an app, including creating an account for discounts, choosing between metered or flat rate taxis, and entering pickup/dropoff addresses.
2) It describes being able to book taxis immediately or in advance, comparing operators, and choosing between shared or private taxis based on price and passengers.
3) The booking process involves checking booking details, payment options, number verification, and receiving confirmations by SMS and email.

This document discusses different techniques for deriving test cases, including:
1. An example of deriving test cases for an adder application by considering equivalence class partitioning and different input combinations.
2. Deriving test cases for a word to PDF publishing application by considering different document types, publishing options, locations, and compatibility scenarios.
3. The technique of combinatorial testing to derive a representative set of test cases by combining variations in multiple test parameters rather than testing all possible combinations.
The document discusses careers in software testing and provides an overview of typical career paths that software testers can take as they gain experience and take on greater responsibilities, either through management roles or by specializing in technical testing areas like performance, security, or automation testing. It also includes a case study showing 76 open testing positions at Microsoft and information about a Meetup event for testers in the Twin Cities area.
The document presents an analysis of seepage issues at the Diyala weir structure in Iraq. A 2D finite element model was created to model the soil and sheet pile foundation. Results found that removing any of the three rows of sheet piles increased seepage quantities, uplift pressures, and exit gradients, though safety factors remained above critical values. Removing the first upstream sheet pile had the largest impact on seepage, while removing the third downstream pile most increased exit gradients. The analyses validated repairing sheet pile defects and sealing cracks could prevent further foundation issues.

7. HMI för aktiva säkerhetssystem
Viktigt vid utveckling av aktiva säkerhetssystem
• Systemet skall inte arbeta emot föraren
• Systemet skall bromsa/styra/etc på ett sätt
som föraren förväntar sig
• Undvika konflikt – förare vs. system
2013-01-09 Christian Larsson - Volvo GTT ATR 7
8. HMI för aktiva säkerhetssystem
Låsningsfria bromsar – ABS
• Utan ABS:
– Inte trycka maximalt
Undvika att
alternativt
hjulen låser sig
– Pumpa
• Med ABS:
– Tryck hårt och bestämt
2013-01-09 Christian Larsson - Volvo GTT ATR 8
9. HMI för aktiva säkerhetssystem
Hur undvika konflikt – förare vs. system?
• Studera föraren
– Simulator, testbana, fältstudier
• Definiera vad systemet ska göra
– På
– Av->På
– På->Av
– Del-lägen däremellan

10. HMI för aktiva säkerhetssystem
• Exempel
– ACC-sensorer slår av:
• ACC-systemet går från assisterande till manuell
– Förare och system har olika intentioner
• System med aktiv styrning aktiveras för att undvika en
upphinnandekrock men föraren styr emot
-> Ingreppet rampas ut och systemet går ner till
en lägre grad av automatisering
– Mer komplexa system skapar fler komplexa
