Wow you know it’s a fun party when the first result needs to specify it’s _not_ radioactive
Oh I see - Uranyl Acetate is radioactive and this replaces it. Fun!
This seems like a friendly chemical too -
“ The chemical properties of Osmium Tetroxide are such that use and handling of the chemical is often considered daunting. Although its volatility and toxicity certainly makes it a dangerous chemical, but when following the proper procedure and taking the necessary precautions, Osmium Tetroxide can be used to its full potential with limited risk to the user.
This is more toxic than glutaraldehyde and has a higher vapour pressure. Particular care must be taken to avoid breathing the vapour or allowing it to affect the eyes. ”
Uranyl acetate for staining is typically depleted and unless you have regulatory issues I don't think the radiation is a big concern, especially when you compare to the very serious toxicity of OsO4 (vapors can react with your eyes and blind you).
Interesting and makes sense! I know nothing but what I read from the stain description haha. OsO4 seems incredibly nasty. So do a few other of the stains!
I believe the author is talking about the OCP (2.0) network card itself, that these adapters internally. The OCP nics are quite cheap compared to pcie - here’s 100GBE for 100!
https://ebay.us/m/HMQAph
This 100GbE card is an OCP 2.0 type 2 adapter, which will _probably_ not work with the PX PCB since that NIC has two of these mezzanine connectors, and PX only one.
What also may not work are Dell rNDC cards. They look like they have OCP 2.0 type 1 connectors, but may not quite fit (please correct me if I'm wrong). They do however have a nice cooling solution, which could be retrofitted to one of the OCP 2.0 cards.
I've also ordered a Chelsio T6225-OCP cards out of curiosity. These should fit in the PX adapter but require a 3rd-party driver on macOS (which then supports jumbo frames, etc.)
What also fits physically is a Broadcom BCM957304M3040C, but there are no drivers on macOS, and I couldn't get the firmware updated on Linux either.
That’s a good point to note! I think the stacking height would matter, but in theory the single connector is still 8x pcie and should link without the upper 8x lanes connected.
Given the details mentioned (9 guard deaths) the "unconfirmed reports" is probably referring to the x post[1] mentioned in the peoplenewstoday.com article. Personally word not somehow getting out of dozens of people being shot seems hard to believe, though not impossible.
The Spectator is 99% opinion pieces. They're not somewhere I'd go for news. It all seems a bit unconfirmed sources. Zhang being purged is confirmed on the BBC and absolutely everywhere else, along with pointing out that there's been a "clean sweep" of senior PLA staff. The street violence seems a bit less corroborated.
(by contrast, while the Daily Mail is absolutely terrible at opinion and domestic news, they seem to have some capacity left for doing overseas reporting that isn't just wire service, so if they report on overseas events you can be reasonably sure that something like that happened)
It would be considered way on the right generally. To the right of the Telegraph, the main right wing broadsheet.
It's a funny old magazine though, they really do get all sorts in there and print stuff that others wouldn't. It's entirely editorial though with huge biases.
I'm glad it exists and read it often, but I'd go checking everything I read in it if I was after some facts.
They also flicker really badly if your power is not perfect, like you have a decent sized training rig on a different circut.
Incandescents are basically little light inductors and I would imagine the luminosity curve would be sinusoidal vs whatever hell a LED driver chip puts out.
I suppose that counts/was caused by a fracture but almost a half meter of gap in the track is nuts. Like describing a limb that’s totally removed as a bone fracture.
Though conceivably the break was very small and a train impacting the slightly lifted rail just caused a good chunk of it to explode.
> Though conceivably the break was very small and a train impacting the slightly lifted rail just caused a good chunk of it to explode.
The crown (top) of the rail seems to be missing after the gap. The crown-less section then continues ~3 meters before it disappears behind the investigator on the left. IDK what that might indicate.
Yes, the “fracture” (the problem was actually at a joint) was there for a while. The missing segment of rail was still there when the train arrived - the derailment affected only the last cars.
The "fracture" being referred to is a weld that somehow failed. The gap you are seeing is because an enormous, heavy train travelling at 200km/h hit that fracture and the rear half of the train derailed, tearing up sleepers and kicking all manner of debris around including ballast and, in this case, parts of newly-fractured (and therefore weakened) track.
Doesn’t anything under 250g basically slip under the radar (not literally radar). Seems like most drones they care about might end up not being trackable anyway.
