We live in a 64-bit world, to the point that many distributors want to stop
supporting 32-bit systems at all. However, lurking within our 64-bit
kernels is a subsystem that has not really managed to move past 32-bit
addresses. The quick merge-window failure of an attempt to use
64-bit addresses in the I/O memory-management unit (IOMMU) subsystem shows
how hard it can be to leave all of one's 32-bit history behind.
We hear about electric vehicles being the future, but for that to happen, people eventually need to be able to drive long distances without getting stranded. For Bloomberg Green, Kyle Stock and Jer…
Service binding and parameter specification via the DNS (DNS SVCB and HTTPS RRs)
This document specifies the "SVCB" and "HTTPS" DNS resource record (RR) types to facilitate the lookup of information needed to make connections to network services, such as for HTTP origins. SVCB records allow a service to be provided from multiple alternative endpoints, each with associated parameters (such as transport protocol configuration and keys for encrypting the TLS ClientHello). They also enable aliasing of apex domains, which is not possible with CNAME. The HTTPS RR is a variation of SVCB for use with HTTP [HTTP]. By providing more information to the client before it attempts to establish a connection, these records offer potential benefits to both performance and privacy. TO BE REMOVED: This document is being collaborated on in Github at: https://github.com/MikeBishop/dns-alt-svc (https://github.com/MikeBishop/dns-alt-svc). The most recent working version of the document, open issues, etc. should all be available there. The authors (gratefully) accept pull requests.
Unlocking complex problems by working with domain experts - UXM
Working with domain experts is an important part of product design, yet it’s rarely covered by design courses where the focus tends to be on working with users. Find out when you should be working with domain experts, how to go about doing this and some hints and tips to ensure that you get the most out of their expertise.
an advanced distribution of the GNU operating system ‑ the GNU Guix website a purely functional package manager, and associated free software distribution ‑ the Guix subreddit I find these descriptions uninspiring and wouldn't be so excited about Guix if that's really all it was. So what is Guix really, how does it relate to these descriptions, and what makes it so compelling and different?
For many years, the bulk of networking over IP has made use of just two
protocols: transmission control protocol (TCP) and user datagram protocol
(UDP). TCP offers a reliable, stream-oriented connection which works well
for a large variety of higher-level network protocols. UDP, instead, makes
a best effort to move individual packets from one host to another, but
makes no promises regarding reliability or ordering. Most higher-level
protocols are built upon TCP, but there are applications which are better
served by UDP. These include:
What is DCCP (Datagram Congestion Control Protocol)? - GeeksforGeeks
A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions.
Building load test infrastructure is tricky and poses many questions. How can we identify performance regressions in newly deployed builds, given the overhead of spinning up test clients? To gather the most representative results, should we load test at our peak hours or when there’s a lull? How do we incentivize engineers to invest time …
