The increasing use of digital video has put into perspective the storage requirements for a large number of video files. Different qualities of videos are available and each of these requires different storage areas. Different variety of devices having different pixel densities uses these files and accordingly has varying video processing capabilities. This paper presents a novel multimedia video encoding/decoding algorithm which is responsive to the device and responds to the device capabilities. This involves a light-weight, multi-layered approach whereby the video streams are divided into different layers and these are differentially loaded as per the quality requirements. This differential loading involves the progressive decoding algorithm for the video stream and henceforth a single file to be used vary the bit rate depending on several factors like the device processing capabilities, available memory, screen width and pixel density for different quality requirements. By in cooperating this method to WebRTC framework, the quality of video can be varied according to the network congestions. Our analysis reveals that this method is far more efficient than transcoding-on-air method which is used by multimedia servers which require special hardware support. For normal servers which use HTML5 for playback of video, this method reduces the total bandwidth required and saves a lot of storage space which results in smooth streaming over the web. This new approach makes the video files adaptive to the different devices on which they are running.

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).

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.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
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
