This presentation aims to give you information about the JavaScript language itself; pros, cons and pitfalls. It will cover the basics and then go into objects, scope, closure and some performance bits.
Front-end Javascript testing is a thing since 3/4 years now, but it’s still a ghost in the dev community: someone believes in it while someone else is not convinced at all.
This talk will tackle the misconceptions about testing, how and what to test, dependencies mocking and strategies to write tests in a profitable way without being afraid.

So you've been toying around with JavaScript. You have a basic feel for the language but don't quiet feel productive, yet. If so, this talk is for you. We'll peel away the abstractions, libraries, and frameworks to uncover the more interesting fundamentals of JavaScript.
Dario Faggioli - Virtualization in the age of speculative execution HW bugslinuxlab_conf
Can you possibly speculate how badly the spectre of the hardware bugs, recently discovered in microprocessors, haunts virtualized systems (like Xen & KVM)? Are things fine, or is everything going to meltdown ? Come to the talk, and let’s discuss this together…
At the beginning of 2018, Meltdown and Spectre taught us that speculative execution can, from deep down inside our super fast processors, pose some security concerns. During the following months, more Spectre variants, L1TF, etc, taught us how really serious such concerns needed to be.
One of the interesting things about this class of security issues, is that they do not come, like most bugs, from someone’s “mistake”. In fact, they represent the failure of fundamental assumptions that CPU designers have been relying on for years.
This talk will give a quick overview of speculative execution, and of how the attacks work, at a high level. Then, it will go through how these vulnerabilities could be exploited in virtualized environments. It will also try to explain what the main mitigations are, and how they work, for the two main Open Source virtualization solutions, Xen and KVM.
Mnogim programerima JavaScript ne predstavlja osnovni programski jezik, već ga koriste ad-hoc, oslanjajući se na koncepte kojima su ovladali u drugim jezicima. To često može dovesti do zabune i do raznih iznenađenja, što dalje neopravdano razvija negativna osećanja prema JavaScript-u. Ova prezentacija otklanja deo te zabune i omogućava jasno razumevanje koncepta nasleđivanja u JavaScript-u

Using Buildout to Develop and Deploy Python ProjectsClayton Parker
Buildout gives you a way to manage, build and deploy your Python project with ease. Large Python projects such as Plone use it to distribute repeatable development environments. Buildout allows you to easily get up and running with your project versus the traditional method of installing all the dependancies and manually configuring your applications instance for each environment. The buildout community is rapidly growing with a large repository of recipes that allow you to extend it's functionality. This talk will show you the basics of using buildout and how to make it a vital part of your project's life cycle.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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.
