Hot Fix Sundae Edition
- 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.
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.
- Facebook is gearing up to launch its own currency, spinning off a new subsidiary called Calibra to focus on financial services. (Tom's Hardware)
All I have to say is Danger, Will Robinson!
- Australia has blocked HorribleSubs and hundreds of other sites. (TechDirt)
Nobody tell them.
- Apparently President Trump is allowed to block people again. (Tech Dirt)
- Out of the world's 500 fastest supercomputers 500 run Linux. (ZDNet)
- Apple Stores suck. (ZDNet)
- Don't link accounts. (ZDNet)
Important note: Even if your online storage provider promises that all your files are encrypted and safe from hackers, even if that's true, it doesn't help if the hacker has your login.
- 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.
You code sixteen apps, what do you get?
Another year older and deeper in debt.
Saint Peter don't you call me 'cause I can't go -
I owe my soul to the Google Play Store.

Having said that it is insane that you can't lock your account to protect you from the SIM swap scam. A customer-focused carrier (hah!) would roll that feature out and brag about it on TV.
As for Google, Twitter, etc., they go out of their way to make it hard to find an actual person to talk to, with the single exception of Google Fi (at least when I briefly had them in 2017). Fi actually encourages you to request a phone call, and they'll call you back (in my limited experience) in a couple of minutes.
