Introduction to specification based test design techniquesYogindernath Gupta
Specification-based test techniques involve deriving test cases from requirements specifications rather than source code. These techniques include equivalence partitioning, boundary value analysis, decision tables, state transition testing, all-pairs testing, classification trees, and use case testing. Coverage criteria measure things like the percentage of partitions or boundaries covered. Specification-based techniques help ensure requirements are thoroughly tested before code is written.
Let us delve upon the various skill levels or knowledge levels for the testing industry being designated as K-Levels.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Biomedical Knowledge Graphs for Data Scientists and Bioinformaticians
RFT Tutorial - 2 How Do We Use An Anchor To Locate A Particular Object Using RFT
1. RFT Tutorial - 2: How do we use an anchor to locate a particular object using RFT?
This short tutorial describes a method of using an anchor to locate a particular object in
RFT.
Use of an anchor is useful in pin pointing a test object, which normally RFT finds it difficult to
differentiate between two similar objects during playback.
This happens usually when two browsers or instances of the same application are open
simultaneously. We can identify the browser and the instances of the application by using a
TestObject reference.
Running more than one instance of an application simultaneously during playback will result in
ambiguity about the target of commands like object() or click().
To solve this problem, we can use "ProcessTestObject" when we call the "startApp" command as
described below.
ProcessTestObject pto1 = startApp("ApplicationOne");
ProcessTestObject pto2 = startApp("ApplicationTwo");
object(pto1, DEFAULT).click();
In the above example, the "ProcessTestObject" functions as an anchor to locate the desired
application.
