Tech News
- Ryzen 3000XT is here. (AnandTech)
3600XT and 3900XT get a 100MHz boost; 3800XT gets 200MHz. Price and all other specs are the same as before. This makes that top boost clock - previously only found on the 3950X - a lot more affordable.
- Kioxia - that is, Toshiba - has a new range of enterprise SSDs out. (AnandTech)
These are available in both PCIe 4.0 NVMe and SAS 24G. The SAS models are actually faster than PCIe 3.0 drives; if you're saying those numbers don't work, that's because they have dual SAS ports and can combine the bandwidth.
Speaking of bandwidth, SATA hasn't seen an upgrade in ages; it should be replaced with USB-C. USB 3.1 Gen 2 is already twice as fast as 6Gbps SATA, thanks to more efficient encoding, and USB 3.2 and USB 4 use the exact same connector and could also run NVMe drives.
Also, if "wuxia" is pronounced wu-sha, wouldn't Kioxia be pronounced...
- AMD also released a new Navi mobile part, the 5600 Pro. (AnandTech)
Found only in the MacBook Pro for now, where it will add $700 to the price, it's essentially an undervolted 5700XT with HMB2 RAM. Way undervolted; it has a TDP of just 50W.
- With up to 8 cores and 8 Vega compute units at 15W, the Ryzen 4000 APUs would be perfect for NUC-like systems. So where are they?
Oh, here they are. (Tom's Hardware)
Price (based on one European listing, so may vary) ranges from $325 with a 4300U to $500 with a 4800U. It supports two SO-DIMMs for up to 64GB of DDR4-3200, one M.2 slot, one 2.5" drive, HDMI and DisplayPort, gigabit Ethernet and WiFi 6. The two USB-C ports also support DisplayPort mode so you can connect a total of four monitors - though one will be plugged into the front because that's where the second USB-C is found.
- A private company plans to launch a communications satellite. (Tech Crunch)
For the Moon.
Whether that means lunar orbit is unclear. The article says it will be placed between the Earth and the Moon, which from an orbital dynamics perspective makes zero sense unless you only want to chat on alternate Thursdays.
Update: L1 point, maybe? Thanks to the commenters.
- Apple, Arm, and Intel. (Stratechery)
This article is full of dumb. It contains some valid insights and hard numbers, but also some total bullshit. Tame Apple press gonna tame Apple press.
- The Netgear M4300 8X8F is the perfect switch for hub site admins cursing their purchasing officer. (Serve the Home)
By which I mean it has 16 10GbE ports - eight RJ45 and eight SFP+. Also it's half-width so you can squeeze it in beside something else.
- Can a packet with an inconsistent length field traverse a router? (ZDNet)
I mean, a switch, sure. But a router? And if bad packets aren't sanitised by default, is that at least configurable?
- Apple's Apple Developer App app now runs on Apple. (Tech Crunch)
And includes stickers.

You could put the comsat at L1, which would be between the two, but I think coverage-wise L4 or L5 might make more sense. I think L4 and L5 are also accrual points, unlike L1, which would require station-keeping.
L3 is right out.
L3 is right out.

There's already a Chinese satellite at L2 (Queqiao), acting as a relay for their lander on the far side of the Moon. Sounds like these folks want to put one at L1, to reduce the size/power requirements for equipment trying to phone home from the near side. Kind of a Luna Of Things hub.
As for routers letting goofball packets through, even OpenBSD's PF firewall doesn't enable scrub by default. I have it enabled on my home router for everything without a problem, but it has broken things in the past (like SSH through an IPSec tunnel for any non-Mac client, or TCP window scaling in certain Linux releases, both ~15 years ago). I expect most home routers don't do much to clean up incoming traffic.

I'm an idiot and didn't even consider the Lagrange points. Yes, L1 makes perfect sense if you can manage the station-keeping.

Yeah, I read waaaaaaay too much of the slightly harder Scifi as a wee one, so the Lagrange points are pretty much burned into my neocortex.
