https://opensource.com/article/17/1/brotli-compression-algorithm?sc_cid=70160000001273HAAQ Brotli is a new open source compression algorithm designed to enable an Internet that’s faster for users. While the Brotli algorithm was announced by Google in September 2015, only recently have the majority of web browsers adopted it and HTTP servers started to offer Brotli compression. Brotli accomplishes better than gzip compression by making use of a →
Here is tear-down of old Zyxel ES-108 10/100Mbit/s Ethernet switch. I had one on my network for many years, but one day it stopped worked and started making whining noise. Look inside. Closer look to details. Main Ethernet switch chip is ADM6999 from ADMtek (now part of Infineon). In addition to it line transformers and power →

http://vitorr.com/post-details.php?postid=2615 The cellular wireless Generation (G) generally refers to a change in the nature of the system, speed, technology and frequency. Each generation have some standards, capacities, techniques and new features which differentiate it from the previous one. Now 5G is hot technology at the top of the hype cycle. But that’s not the end →
https://m.slashdot.org/story/333069 The Internet Task Engineering Group (IETF) has approved the new HTTP status code 103. The 103 (Early Hints) informational status code indicates to the client that the server is likely to send a final response with the header fields included in the informational response. →
It seems that we are going to get some kind of 5G standard this year. But it will not be the glamorous rumored 5G industry revolution we have been hyped for – but something much less than that (but still more than what 4G offers). To get the standard made in time 3GPP puts some →
https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-protocol-leaves-wi-fi-traffic-open-to-eavesdropping/ An air of unease set into the security circles on Sunday as they prepared for the disclosure of high-severe vulnerabilities in the Wi-Fi Protected Access II protocol that make it possible for attackers to eavesdrop Wi-Fi traffic passing between computers and access points. There is a proof-of-concept exploit called KRACK, short for Key Reinstallation Attacks. KRACK →
https://spectrum.ieee.org/tech-talk/semiconductors/optoelectronics/topological-laser-cavities-could-revolutionize-optoelectronics A new type of laser cavity that builds off a Nobel-winning development in physics can take on any shape and switch the flow of light with a magnetic field. Kante and his colleagues describe their so-called topological cavities in the current issue of Science. Normally, a laser cavity, where light amplification takes place, is shaped like →

While the performance discussion may often begin with talk of throughput numbers expressed in Million-packets-per-second (Mpps) values across Gigabit-per-second (Gbps) hardware, it really is only the tip of the performance iceberg. The most common requirement is to have →
