The 31-year-old information security researcher and post-doctoral fellow at Austria&rsquo;s Graz Technical University had just breached the inner sanctum of his computer&rsquo;s central processing unit (CPU) and stolen secrets from it. <a href="https://www.reuters.com/article/us-cyber-intel-researcher/how-a-researcher-hacked-his-own-computer-and-found-worst-chip-flaw-idUSKBN1ET1ZR">Reuters</a></p> <p>Also:</p> <ul> <li><a href="https://cyber.wtf/2018/01/05/behind-the-scene-of-a-bug-collision/">Behind the scenes of a bug collision</a></li> <li><a href="https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre-or-meltdown/">Why Raspberry Pi isn&rsquo;t vulnerable to Spectre or Meltdown</a></li> </ul> <p>TechSpot&#39;s coverage:</p> <ul> <li><a href="https://www.techspot.com/article/1556-meltdown-and-spectre-cpu-performance-windows/">Patched Desktop PC: Meltdown &amp; Spectre Benchmarked</a></li> <li><a href="https://www.techspot.com/article/1554-meltdown-flaw-cpu-performance-windows/">Testing Windows 10 Performance Before and After the Meltdown Flaw Emergency Patch</a></li> <li><a href="https://www.techspot.com/news/72576-massive-cpu-flaws-get-name-meltdown-spectre-what.html">Massive CPU flaws Meltdown and Spectre -- what you need to know</a></li> </ul> <p><strong>Why Sony&rsquo;s Trinitron tubes were the best </strong>If you&rsquo;re old enough to remember Cathode Ray Tube (CRT) Televisions, you probably remember that Sony sold the top products. Their Trinitron tubes always made the best TVs and Computer Monitors. [Alec Watson] dives into the history of the Sony Trinitron tube. Sony Color TVs didn&rsquo;t start with Trinitron &mdash; for several years, Sony sold Chromatron tubes. Chromatron tubes used individually charged wires placed just behind the phosphor screen. <a href="https://hackaday.com/2018/01/03/why-sonys-trinitron-tubes-were-the-best/">Hackaday</a></p> <p><strong>400Gbps Ethernet specification arrives enabling insanely fast file transfers </strong>Even Goose and Maverick would have to be impressed with the newly approved IEEE 802.3bs standard. The specification lays out the requirements to enable blazing fast connectivity to the tune of 200Gbps and 400Gbps across various interconnects. <a href="http://www.pcgamer.com/400gbps-ethernet-specification-arrives-enabling-insanely-fast-file-transfers/">PC Gamer</a></p> <p><strong>To serve man, with software </strong>I didn&#39;t choose to be a programmer. Somehow, it seemed, the computers chose me. For a long time, that was fine, that was enough; that was all I needed. But along the way I never felt that being a programmer was this unambiguously great-for-everyone career field with zero downsides. There are absolutely occupational hazards of being a programmer, and one of my favorite programming quotes is an allusion to one of them: <a href="https://blog.codinghorror.com/to-serve-man-with-software/">Coding Horror</a></p> <p><strong>Midrange, high-end graphics card prices to rise </strong>Graphics card vendors are expected to raise their prices for mid-tier to high-end models by US$5-20 in the near future to reflect increasing product costs caused by the tight supply of memory devices and GPUs. Since demand for graphics cards from the cryptocurrency mining segment has not waned as quickly as expected, GPU supply remains tight in the first quarter of 2018. <a href="http://www.digitimes.com/news/a20180103PD211.html">DigiTimes</a></p> <p><strong>China sees record tech funding in 2017 </strong>China&rsquo;s startups and tech giants pulled in a record US$58.8 billion from investors in 2017, according to the Tech in Asia database. That&rsquo;s up a few billion from 2016&rsquo;s tally. There was no sign of the giant bubble that some dreaded in 2016 after an explosion of local tech funds poured new &ndash; and very inexperienced &ndash; cash sources into the market. <a href="https://www.techinasia.com/china-tech-funding-record-high-2017">Tech In Asia</a></p> <p><img src="https://www.techspot.com/images2/news/bigimage/2018/01/2018-01-07-image.png" /></p> <p><strong>Linux Mint 19 codenamed &ldquo;Tara&rdquo;</strong> The first release in the upcoming Linux Mint 19.x series will be named &ldquo;Tara&rdquo;.

Citing the need for even greater amounts of display bandwidth, the standards association has stated that they&rsquo;re looking to double the bandwidth available versus the current HBR3 signaling standard. The goal is to publish the standards update in the next 18 months, which would put an announcement in a 2019 timeframe with hardware in 2020 or beyond. <a href="https://www.anandtech.com/show/12213/vesa-announces-work-on-next-displayport-standard">AnandTech</a></p> <p><strong>Chrome is turning into the new Internet Explorer 6 </strong>Chrome is now the most popular browser across all devices, thanks to Android&rsquo;s popularity and the rise of Chrome on Windows PCs and Mac computers.

    400Gbps Ethernet specification
    The specification is not actually an Ethernet specification, that makes it a Fiber specification.

    Ethernet isn’t tied to twisted pair copper. Ethernet works over a variety of mediums including multimode and single mode fiber.

    The Ethernet roadmap is now a bit dated but has a breakout. http://ethernetalliance.org/roadmap

    802.3 is by definition Ethernet I believe.

    You need to be paid a bounty for finding a bug in the system.

    I just want clean stable broadband (which I define as 25Mbps and up) at a reasonable price. Will this help?
