• There's a serious flaw in Linux networking that lets attackers remotly DOS or even crash your server.  (Ars Technica)
  
  Fortunately there's a simple mitigation; it just slows down new connections slightly.  No impact if the network is robust, a few tens of milliseconds if there's packet loss.  
  
  Poke poke.
  
  And we're safe.  In theory.
  
  
• PCI Express 6.0 is on its way.  (AnandTech)
  
  This will be double the speed of PCIe 5.0, which will be double the speed of PCIe 4.0, which is double the speed of PCIe 3.0 that everyone currently uses.
  
  Yes, this is a dramatic acceleration of upgrades.  We were all stuck on PCIe 3.0 far longer than anyone had planned, and the PCI-SIG committee is trying to catch up again.
  
  PCIe 6.0 uses the same signal rates as 5.0 but encodes two bits per clock using four voltage levels - a technique called PAM4 and used in high-speed networking - much the same as MLC flash encodes two bits per cell by having two intermediate levels between empty and full.
  
  This means it can work with similar materials and designs as PCIe 5.0, while keeping full backward compatibility.  The downside is that it makes the controller circuitry a lot more complicated; you not only have to deal with intermediate levels, you have to deal with intermediate levels accurately and consistently within 60 picoseconds.
  
  The final spec is due in 2021 and first products in 2023, but I wouldn't expect this to reach consumer systems for a while.
  
  The impetus for this is terabit networking, which requires a ton of expansion slot bandwidth.  And the impetus for that is cloud-scale virtualisation: If your interconnect is fast enough your entire datacenter becomes one huge massively fault-tolerant server that you can dynamically subdivide to suit needs that change from one second to the next, without needing the level of over-provisioning that currently entails.

• Google plans to spend a billion dollars on worker housing.  (Thurrott.com)
  
  Or they could move offices to somewhere that isn't a blighted far-left hellscape.  Just a thought.

  Another year older and deeper in debt.

• YouTube, Twitter, and Pinterest's ham-fisted censorship efforts are drawing attention beyond the usual tech circles.  (PJ Media)
  
  YouTube explained to James O'Keefe what triggered the censorship: It was the inclusion of a key piece of documentary evidence proving Pinterest's own fraudulent censorship.
  
  Democracy dies in Darkness, they say, and new media and old media alike are here to make sure of it.

• SD Express is on its way with chips for cards from Phison and chips for readers from Realtek.  (AnandTech)
  
  Basically a single lane of PCIe 3.0, so speeds close to 1GB/s, and supports device sizes up to 128TB.  Which will be great right up until you sneeze and you lose the entire corporate database cluster.

• A 64 core Threadripper could be coming later this year unless it isn't.  (WCCFTech)
  
  This week's WAN Show (Other Linus' weekly news show) talked about how this seems impractical and expensive for such a niche product.  But even more than with Threadripper 1 & 2, this will just be an alternate power profile for an Epyc chip.  Allow it to draw 250W instead of 180W, and let your packaging designers go nuts.
  
  It's the same socket as Epyc, same chiplets, same substrate.  Gen 1 had a fixed limit of 4 memory channels, but now with the I/O die they don't even need to do that.  Epyc could run just fine on Threadripper boards and vice versa, with a suitable BIOS.

• AMD's X570 chipset has been making all the noise recently but B550 and A520 are also on their way.  (Digitimes)
  
  These don't support PCIe 4.0; they are updated versions of the B450 and A320 (I don't think there was ever an A420).  But you get 20 lanes of PCIe 4.0 from the CPU regardless.
  
  
• So just how fast is PCIe 4.0?  On, for example, that upcoming Phison SSD controller? (Tom's Hardware)
  
  They actually got their hands on a sample device and were able to run a full suite of tests, using an adaptor card that converts PCIe 3.0 x 16 to PCIe 4.0 x 8 (since PCIe 4.0 motherboards will be scarce for another three weeks).
  
  It hit 5GB/s in one test, but while it did well overall the faster interface alone was not enough to make it the unqualified winner.
  
  
• It's 2019.  Why aren't Docker and LXC/LXD secure by default?  (Bleeping Computer)
  
  And MongoDB, Redis, Elasticsearch...  It's not enough to have a guidebook to securing commonly used infrastructure; it must install that way automatically and have a guidebook to punch holes in the security model only when needed.
  
  
• Huawei has put its Mate X on hold following Samsung's trouble and the fact that no-one will buy it anyway.  (Thurrott.com)
  
  
• YouTube censored a video discussing Pinterest censoring links to conservative blogs.  (One Angry Gamer)
  
  I have no particular need to see Glenn Reynolds naked but at the same time I'm pretty sure Instapundit doesn't prominently feature nudity.
  
  This comes a day after Twitter suspended Project Veritas for reporting on the same incident.

• Possibly the coolest little tech tidbit of the day is from AMD again.
  
  The new Ryzen 3000 family consists of one or two CPU chiplets (up to 8 cores each) and an I/O die handling memory and PCIe 4.0 and some built-in SATA and USB and other functions.  The chiplets are connected to each other using AMD's Infinity Fabric 2 at 50GB/s.  On the 12 and 16 core chips the two CPU chiplets are connected directly to each other, and each is also connected to the I/O die. 
  
  [Update: Apparently, unlike earlier Epyc and Threadripper chips, the CPU chiplets only talk via the I/O die, and that handles all the routing.  That saves a lot of traces on the package, at the expense of latency.  But there's no practical way to route 28 interconnects on a 64 core Epyc anyway, which is what would be required.  First generation Epyc only requires 6 such links.]
  
  The I/O die connects to the X570 chipset over PCIe 4.0.  Like the I/O die, the chipset includes a bunch of PCIe 4.0, SATA, and USB.
  
  Very much like the I/O die, in fact, because it is the I/O die.  The I/O chip on the motherboard is the exact same chip as the one on the CPU.
  
  Which in theory means that both the CPU and the X570 have some tricks up their sleeves that weren't previously discussed.
  
  
  
  
  
• All those messy Star Control lawsuits and countersuits have been settled amicably for a jar of honey and a pint of mead.  (PC Gamer)
  
  As Brickmuppet notes, I am never facetious.  I don't need to be.

  "We added a section in which I'll be working with Paul on beekeeping. He's going to send me some meade, I'm going to send him some honey. I don't think the lawyers were particularly enthusiastic about us incorporating some of this into the agreement. I did a tutorial video on beekeeping I was going to send over but got stung in the video, so thought better than to actually send it."

• AMD's Ryzen 9 3950X features 16 cores / 32 threads, a top clock speed of 4.7GHz, and a 105W TDP.  (AnandTech)
  
  $749, available in September.
  
  That's a lot of money for a mainstream desktop processor, but then, that's a lot of cores for a mainstream desktop processor.
  
  If you want all the technical details, AnandTech has those too.
  
  
• AMD's Ryzen 3200G provides 4 cores / 4 threads at 4GHz for $99.  (AnandTech)
  
  That's a bit more affordable.  Also includes Vega 8 graphics and DDR4 2933 support, with a 65W TDP.
  
  The 3400G has 4 cores / 8 threads, runs at up to 4.2GHz, Vega 11 graphics, $149.
  
  
• AMD's Radeon 5700 XT is the first Navi product to ship.  (AnandTech)
  
  9.75 TFLOPs, 225W, 8GB 14Gbps GDDR6 RAM, $449.  Oh, and it's PCIe 4.0.
  
  The Radeon 5700 non-XT delivers 7.9 TFLOPs at 180W for $379.  Still with 8GB of 14Gbps DDR6 RAM.
  
  The 5700 XT seems to perform better than the RTX 2070 on the whole, but wait a month for third-party benchmarks.
  
  
• Some companies not called AMD probably did something too.
