5G in US averages 51Mbps while other countries hit hundreds of megabits
It's an upgrade over 4G but not a huge one due to reliance on low-band spectrum.
Average 5G download speeds in the US are 50.9Mbps, a nice step up from average 4G speeds but far behind several countries where 5G speeds are in the 200Mbps to 400Mbps range. These statistics were reported today by OpenSignal, which presented average 5G speeds in 12 countries based on user-initiated speed tests conducted between May 16 and August 14. The US came in last of the 12 countries in 5G speeds, with 10 of the 11 other countries posting 5G speeds that at least doubled those of the US.That's because we don't have 5G in the US. We mostly didn't get actual 4G. They got permission to rebrand 3G as 4G under some conditions to avoid having to roll out actual 4G using LTE instead (LTE is a 3G tech with permission to be called 4G even though it didn't meet the requirements as it was an older generation tech.) There is no working 5G equipment allowed to be sold in the US, so they've allowed them to call some 3G and pretty much any 4G tech 5G to make it sound like we are rolling out 5G - at maximum speeds that are slower than 4G in the former USSR was doing in 2016!!

Why not? Import restrictions?

Yes, 5G providers with working equipment are few and far between, to the point that Huawei is the only key player. The US bans Huawei software (not hardware.) So while you can physically buy the hardware, you can't get the firmware for it legally. We support ISPs and have been through the "there's no vendor, at any price, that even offers 5G currently inside the US". What we can buy off of the shelf in the third world, is out of bounds here.
So US-friendly vendors, like Samsung, are scrambling to build 5G tower radios. But as of a couple months ago, no working hardware was on the market yet. There's some hardware that doesn't work. But nothing functional like Huawei has. So the focus now is 100% on rolling out 5G-branded 3/4G solutions.

The issue with 4G in general was/is that unlike 3G, there was never any minimum bandwidth requirements, so operators could roll out equipment that provided dial-up speeds and call it 4G. I guess it's the same story with 5G.

TikTok CEO quits as company reportedly plans sale to Microsoft, Walmart
Can’t do global work if the White House is forcing sale of US business, Mayer said.
TikTok CEO Kevin Mayer, who only began the job on June 1, is heading right back out the door again as the company plans a sale under pressure from the White House. "In recent weeks, as the political environment has sharply changed, I have done significant reflection on what the corporate structural changes will require, and what it means for the global role I signed up for," Mayer wrote in an email to TikTok employees late Wednesday. "Against this backdrop, and as we expect to reach a resolution very soon, it is with a heavy heart that I wanted to let you all know that I have decided to leave the company." -

Going all-in on remote work: The technical and cultural changes
The new way of work requires a new way of managing, whether you like it or not.
Welcome to the fifth installment of our Future of Business series. Over the last few weeks, we've talked about home office ergonomics, the challenges of collaborating with remote colleagues, work strategies, and the inevitable return to the office. We've also asked Ars readers to weigh in on what has been working for them as they work remotely. -

Interesting read from Cloudflare on yesterday's cluster from CenturyLink
Analysis of Today's CenturyLink/Level(3) Outage
Today CenturyLink/Level(3), a major ISP and Internet bandwidth provider, experienced a significant outage that impacted some of Cloudflare’s customers as well as a significant number of other services and providers across the Internet. While we’re waiting for a post mortem from CenturyLink/Level(3), I wanted to write up the timeline of what we saw, how Cloudflare’s systems routed around the problem, why some of our customers were still impacted in spite of our mitigations, and what appears to be the likely root cause of the issue.

With the latest couple of outages I wonder about the availability, at least for some of Cloudflare's customers. It has to be way below 99.9% by now.

It's hitting them hard. But hitting other customers, too. It's hard to classify something as a CloudFlare outage when the outage is not at CloudFlare but "somewhere on the Internet" after it has left CloudFlare and before it gets to the customer.
Like.... McDonald's is closed when it's driveway is closed. But is it closed when the road in front of the driveway is closed? What about if the highway between your house and there is closed? Or what if your car won't start?
There's a clear demarcation that when it's on premises and there is an outage, it's their outage. And when your car won't start, it's a car outage. But in between, in road terms we consider all of it an infrastructure outage and it is not an outage to you or the vendor, but the public utility space that you share between yourselves.

If it's CF's job to route their traffic around the "outage" and they're not able to (for whatever reason), then as long as that is the case CF has an outage as well.
Only those that are single homed to CenturyLink's network should have been affected. Datacenters that are single homed are unusual though, because you have zero redundancy.
But whatever...

That's not quite true. For example, in this case, they DID route around, but all other carriers were not working because of their connections to CenturyLink.
If the Internet is down, you can't route around. The Internet design doesn't allow for any company to just route around, everything depends on BGP level cooperation. If any player doesn't play nice, the only option is for ALL other carriers to drop them, completely. CF has no power over that.

That too, but they pointed out that all carriers were impacted. CL's outage hit everyone that shared BGP with them.

TLS/SSL certs are dead after Sept 1st, 2020
A bit click baity I know, to summarize any cert that would be lived for 2 years or more will no longer be supported on Apple, Chrome or Firefox, come Sept 1st, 2020.
Time to get to renewing your certs on a yearly schedule (or use something like Let's Encrypt with certbot).

More clearly, any 2 year cert issued on Sept 1, 2020 or later. Anything issued today (August 31, 2020) is is still valid to be a 2 year cert.

Black Lives Matter: Ubisoft removes Tom Clancy image
Ubisoft has apologised for giving fictional terrorists the symbol of the raised fist, associated with the Black Lives Matter movement, in its new mobile game, Tom Clancy: Elite Squad.
The company faced a backlash after the video game's trailer was released.
Players have to kill members of the fictional group, Umbra, which fuels civil unrest with acts of terrorism. Ubisoft said showing the fist symbol at an Umbra meeting in an opening sequence had been "insensitive and harmful"."We have listened to and appreciate the players and the broader community who have pointed it out and we apologise," the games giant said. The image would be removed from the Android version of the game on Tuesday and from the iPhone version "as soon as possible", it added. A senior Ubisoft programmer had tweeted the trailer was "gross and extremely disrespectful". -
Samsung accidentally leaks details of its upcoming 980 Pro NVMe SSD
The PCIe 4.0-based 980 Pro looks fast—but it may not really be a “Pro” anymore.
Everybody makes mistakes sometimes, and it looks like Samsung made one yesterday: the product page for its upcoming 980 Pro NVMe SSD went briefly online before being discovered by TechPowerUp and then getting yanked offline again. The 980 Pro is a particularly interesting product, since it shakes up Samsung's lineup in several ways. We've known since CES 2020 that it would be the company's first consumer-available PCIe 4.0 SSD. The higher-bandwidth PCIe4 bus allows for a blistering throughput increase; the 980 Pro is rated by Samsung for up to 7000MB/sec of throughput, compared to the PCIe3 970 Pro's 3500MB/sec. Unfortunately, the 980 Pro's sharp increase in throughput comes with an equally sharp decrease in warranted write endurance. -
