Mass and weight
Mass is a measure of the amount of matter in an object and does not change in different environments, while weight is the force of gravitational attraction on an object which does change depending on location. Weight is calculated as mass times the acceleration of gravity (w=mg), where mass is measured in kilograms and weight in newtons. On the moon, an object's mass would remain the same but its weight would be about 1/6 of what it is on Earth due to the moon's lower gravity.

Chemical reactions final ii (1)new
1) A chemical reaction is a process where one or more substances are converted into different substances with different chemical compositions and properties. Examples of chemical reactions are carbon reacting with oxygen to form carbon dioxide and two hydrogen gases reacting with oxygen to form two water molecules.
2) There are several types of chemical reactions including combination reactions, decomposition reactions, displacement reactions, double displacement reactions, and oxidation-reduction reactions.
3) In a combination reaction, two or more reactants combine to form a single product. Examples are magnesium reacting with oxygen to form magnesium oxide and carbon reacting with oxygen to form carbon dioxide.
Chemistry.sumepro
This document discusses the four main types of chemical reactions: combination reactions, decomposition reactions, displacement reactions, and double displacement reactions. It provides examples and balanced chemical equations to illustrate each type of reaction. Combination reactions involve reactants combining to form a single product. Decomposition reactions involve splitting a single reactant into simpler products. Displacement reactions involve a more reactive element displacing a less reactive one. Double displacement reactions involve the exchange of ions between reactants to form new ionic compounds.
Types of Reaction
This document outlines four basic types of chemical reactions: combination reactions, decomposition reactions, substitution reactions, and double replacement (ionic) reactions. It provides examples of each type of reaction and describes their key characteristics, such as two or more substances combining in a combination reaction or one element replacing another in a substitution reaction. Knowing the different reaction types allows chemists to predict products from given reactants.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.
Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile.
