Recent innovations in the manufacturing and design of steel studs have produced studs that use less steel yet perform as well and better than traditional smooth-faced studs. This article addresses the challenge architects face when designing and specifying metal stud framing.
1. There is a difference between vapor retarders, vapor barriers, and waterproofing materials and when each should be used under a concrete slab on grade.
2. Vapor retarders are used to slow the transmission of water vapor from the soil into the building through the slab, while vapor barriers completely block vapor transmission.
3. Proper installation of a vapor retarder under the slab is important to prevent moisture-related problems with flooring materials and to restrict soil gases from entering the building.
This newsletter discusses BIM integration with project specifications using Revit parameters, a free file renaming utility, and measuring construction document quality through a quality assurance review process. It provides an example of how planned QA reviews for 7 school projects significantly reduced RFIs and change orders during construction by identifying issues earlier. The article recommends design teams aim for a quality ratio of 8-10 comments per drawing to coordinate documents thoroughly before bidding. This leads to lower contractor contingency, fair project pricing for owners, and strengthened professional reputation through higher quality deliverables.
This document discusses zinc coatings for metal studs used in construction. There are different types of zinc coatings but continuous sheet galvanizing is most common for metal studs. This process involves passing steel through molten zinc to apply a protective zinc coating. Standards specify minimum coating thicknesses of G40, G60, or G90 for interior or exterior use depending on corrosion risk. Understanding coating types and thicknesses is important for selecting the proper protection for metal studs in different environments.

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).

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.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients.
