to clear up the hdmi/vga security talk from the last page here's some probable considerations that got overruled by time - vga is pretty simple and is one-way video, whereas hdmi can do everything including networking with manufacturer extensions to a very open protocol so 'validating' it is a never-ending task - on the other hand hdcp keeps being popped open and there's a great writeup on key extraction for hdcp 1 floating around - tempest is screen emissions mainly and if you're into sdrs you can try it at home since you have time to spare - these kind of attacks do still get used for intel gathering but pale in comparison to what the cabinet would just handover to a friendly consultant so it's more security science than practice

Darth Walrus posted:Lancet says the average time from infection until death is eighteen days, so we'll likely be on a steady exponential rise until early next week when the effects of the lockdown become apparent. i mean i know which one the tories are wanting for Number but we're in this for the the very long haul and wuhan's only slowly starting to get back after an absolute lockdown. ultimately because no one wants to be honest with the public there's going to be a quiet reseed globally when these lockdowns are lifted prematurely, and everyone's going to act surprised when we go into lockdown mk2 maybe let's try this time and the concept of an antibody test meaning you go back to work is comical. you're still be able to carry it from place to place, you just won't be incubating it - it'll still happily stick to your clothes and move from surface to surface

ThomasPaine posted:Even with an imperfect lockdown, it is absolutely not going to take 9 months to get the numbers under control well enough to relax the lockdown. wuhan is looking at a 3 month absolute lockdown, and that's with widespread testing and a far more comprehensive understanding of essential worker. the virus is still spreading in the uk, we've just slowed it down significantly goddamnedtwisto posted:I think we'll probably end up playing peekaboo with the disease like that article suggested (and I roundly rubbished) a couple of weeks ago. Wait for deaths to drop below a certain level, unlock, then lock back up when the numbers start going up again, or maybe the same but with ICU bed occupancy. It's a long loving way from ideal (and the one area where I sort of agree with the nudge unit people - the observance of each successive lockdown is going to get worse and worse) but absent a viable treatment or vaccine it's about the only way even vaguely acceptable to the NUMBER crowd who still are basically in control of the response across the West.

goddamnedtwisto posted:This seems a fairly big claim IMO. If we take the poll in the last thread as a survey of how many people read/post in this thread, there's been at least 5 symptomatic cases out of 375*. Leyton Orient have had 4 confirmed cases in their staff of 50ish, and they definitely don't have the exotic lifestyle excuse of Premiership clubs (their youth team take the Central Line between their training ground and academy). Assuming the 33% growth a day number is right, it only takes 33 days to go from 100 cases to 690,000 (near as dammit 1%) - given we had the first confirmed cases at the beginning of February, I suspect we've gone *way* past that number now, probably nearer 10% than 1%. everyone keeps wishing it's the case, but that hasn't changed reality and i strongly doubt it'll change it if we continuing wishing even harder

yeah as death reporting turns to what the certificate mentioned to account for supposed cases vs absolutely confirmed it'll be "x died with covid" or "x died with presumed covid" based off of the medical professional's opinion scotland's switching to reporting deaths from certificates from next week so presumably the rest of the uk will as well. that'll increase the accuracy of figures as well as they can't go "well they were never confirmed so let's not count that one"

British Prime Minister Boris Johnson said on Friday he was remaining in isolation with mild symptoms of the coronavirus, including a high temperature, seven days after he first tested positive. “Although I’m feeling better and I’ve done my seven days of isolation, alas I still have one of the symptoms, a minor symptom, I still have a temperature,” Johnson said in a video message posted on Twitter. “So in accordance with government advice I must continue my self isolation until that symptom itself goes,” Johnson said.

there's an interesting document that appeared on scotgov: Guidance from the Chief Medical Officer (CMO) on treating patients with COVID-19. i'll quote the work safe relevant parts for how the uk is handling this in a clinical setting on paper: quote:6.3 Removal from Isolation quote:Patients admitted to hospital where COVID-19 is suspected should have throat and nose swabs sent for PCR testing. The throat is swabbed first and then the nose. Swabs must be either the Virocult or Copan swabs for virology testing. Note that false negatives can occur with the PCR test, if swabs have been inappropriately or poorly taken. A video of how to obtain throat/nose swabs can be viewed here. quote:If clinical assessment suggests the person has an increased degree of frailty (a CFS score of 5 or more), there is good evidence regarding the expected benefit of critical care organ support. In particular, studies from China, Italy and the UK suggest that people over the age of 70 who are admitted to ICU have a very high (greater than 70%) rate of death. This risk increases with advancing age. Significant cardiovascular, respiratory or other comorbidities confer an even higher likelihood of death, even with intensive care support. To ensure the optimal use of ICU resource, and that patients are not subjected to futile interventions of no benefit, a realistic assessment of outcomes for different treatment options must be communicated to patients, their families or carers in order to facilitate shared decision-making. Decision support tools (where available) may be useful to inform both patients and clinicians. quote:7.4 Non-invasive ventilatory support quote:NSAIDs should be used with caution in patients who may have COVID-19, however if the patient is in the last days of life their use may be appropriate. there's also this visual guide: https://www.gov.scot/binaries/conte...pril%2B2020.pdf i haven't seen a similar visual on clinical features elsewhere so can't judge but hey they're the professionals so it has to be based on some data the scotland briefing was a few hours ago and had some gems in it as well: https://twitter.com/i/broadcasts/1BRJjQWvEmjGw - the 100k pledge was brought up. in nhs scotland there's currently 1900 tests/day capacity which will rise to 3500/day by the end of the month. there's testing done outside of there and the topic kept being turned around to the uk aiming for 25k for end of the month if we're comparing on the same basis - the 100k figure is including outside nhs capacity which all 4 bodies are working on - there were 200k vulnerable people to be lettered, but that's now revised to 120k after de-duplication, letters are out to 110k of them now - some schools will be kept open over the holiday for key workers children - on peak being "in a week" - political side: extreme emphasis that there is no data to show that, do not listen to the media on this as there's a false expectation being made, everyone wants this to be over soon but we don't have anything to show that will be the case - cmo was even clearer: we don't have the data to support that. we may have data over the next 2-3 weeks to get an idea, but current shift is from mathematical models to real-world data in changing how to inform strategy that is locally relevant. now is not the time to think this will be over soon - we have always said many months will be needed to get on top. issue is the virus resurfacing if we relax and the public become less stringent on measures. mention of other countries doing this and being hit with a worse peak than wave 1. so if you want to hear about what SAGE are actually telling every CMO before it gets political filters look at the scotland briefing imo. there may be some similarity in what i've been saying that their advice

goddamnedtwisto posted:The servers supplying/holding the keys being located in China is a monumental fuckup. In fact it's not even a fuckup, it's way beyond the reach of Hanlon's Razor - there's literally no way that PLA don't have complete access to everything on that server. It's almost certain that's the actual reason that they're even there, because it's extremely unlikely PLA would actually allow a Chinese company to develop a comms method without giving them access. At the very least you'd expect Zoom to have said "Hey, why don't we just host this in the same place as the rest of our servers" and, you know, actually expected a solid technical reason why not (which I certainly can't think of). quote:I'd be extremely leary of using Zoom even for company-confidential communications in a situation like that, that we had an actual Cabinet meeting using it (when approved teleconferencing applications, okay all the way up to TOP SECRET and beyond, exist and would certainly be available to the loving Prime Minister) is completely inexcusable.

Stopping of COVID-19 isolation and IPC measures if patient staying in hospital quote:6.3 Removal from Isolation quote:If there is a high clinical suspicion of COVID-19, and negative initial tests, repeat sampling is required. Deep respiratory samples (sputum/tracheal aspirate) have a higher sensitivity than nose/throat swabs, so if a patient has a productive cough then sputum should also be sent for COVID-19 testing. Under no circumstances should an induced sputum be performed.
