I don't condone the attempted blame-shift but surely if these records were important enough to warrant dismissal then there should perhaps have been some kind of formal archive process. If nothing else, to prevent alteration after filing date &c.

When I did lesson observations as part of local quality assurance, we had to upload completed paperwork to a system that time stamped everything.

Cow boxes

They arrived one fine morning in Brum resplendent in their cowness. A Pentium P60 with 8 Mb RAM and a (huge) CRT. Unpacked, linked together and they ran Windows 95. Then a memory and hard drive upgrade and Windows 98. Briefly Sun Java Desktop (which was actually Linux and could not be got working with the Sportster modem). Replaced by an HP box, then an Apple iBook.

I spent (relatively speaking) huge amounts of money on those computers. Now it is a recycled Thinkpad and Slackware...

Hello All

Housing Cooperative tenant here - couple of hundred tenancies:

We have Dave with the Van for minor repairs (flush not working, gutter fell off in the wind, fence fell over &c) and triage of more major work.

Contracts with a gas fitter, electrician, plumber and roofing/larger build jobs contractor including emergency call-out

Cyclic maintenance (new kitchens/bathrooms/doors/windows) jobs go out to tender, usually bundled into 10 house lots.

Works for us and the transaction overhead is a phone call to Mavis. Nothing like £40 per household!

Edit: QA contractors have to be on the qualified list held by the housing management agent. Published criteria and appeals process if any company refused &c.

Research project...

"[snip] they are removed by the fact that what should be an instinctual experience comes with a set of rules defined by Microsoft"

I've paid the bills for decades by organising small groups of people for face to face interaction at regular times of the day/week for extended periods (teaching). I think that there is a lot in the psychology mentioned by Lanier that is valid.

BUT as OA says this is really still looks like a research project to me.

The key is the 'set of rules' which are usually negotiated (tacitly) between participants early in the lifetime of a group within institutional norms (c.f Goffman and Tuckman) so it feels 'normal'. Trying to force those on people is just going to seem weird to the participants.

I also was amused by the use of a psychology excuse for a technical issue: if you pop to the loo part way through a face to face lesson, it is very unlikely (to the extent that I can't remember an instance in 30 years) that anyone will hop into your seat while you are out of the room.

Re: At a loss

AlphaSmart Neo had usb, you plugged it in and pressed the button and your PC assumed it had a new USB keyboard and sent the 'input' to whatever window had focus.

The previous AlphaSmart USB based devices that I had a few of about 10 years ago survived being lent out and taken home by various students very well. Clunky and unattractive so no theft, no user accessible software to mess about with, and no storage to lose. Just had to watch the AA batteries on the older models.

Re: At a loss

Or in my case just pulling the USB WiFi adaptor out of its socket...

I find it easier to focus on things if I set up a special environment for the activity. E.g. when preparing maths lessons I have an old shoebox with the regulation scientific calculator, the maths instruments, a clip board and white paper, pencils, blank 'short' lesson plan templates and the recommended textbook and revision guide. This box is kept in a bureau of the kind where a flap folds down to provide a work table. Once planned up and written out, I hit the laptop and assemble/edit the resources and check the Web sites for video snippets. That way I'm selecting the resources that fit my plan for a specific class and not letting the available resources drive the plan.

Perhaps it is the same for writers who compose on the screen. A physical device associated with a specific location may be the mind trick that drops them into the 'flow state'. £40 might not appear expensive in that case.

I miss three pieces of software from my MacOS days: Preview, Textedit and Eastgate systems' Tinderbox. Preview could copy diagrams and snippets from a PDF file and paste them into textedit as vector images. Textedit was 'rich' enough for my needs. You could probably project manage something like a feature film with Tinderbox.

Re: Oh No Surely Not...

"This was on Radio 4 yesterday (they were talking to an ex-junior doctor academic). Those on near minimum wage just take the incoming calls from people who think they might be positivie. The clinical tracers are the ones who make the outgoing calls to those who are confirmed positive."

Numbers look wrong way round for that.

Fred(a) gets a positive test, phones up, gives minimum wage person the contact list with (say) 10 names.

Clinical tracers have to do 10 phone calls, each of which could generate n new contacts, including Freda of course

One new positive test generates a large cascade of follow ups.

Re: Sage & onion

@Dr Syntax

I'm a bit worried about the trend towards criticism of epidemologists and public health modellers generally based on micro-analysis of small samples of particular implementations of models. People are playing defence lawyer when they should be looking at the basics (one person infects between 2.4 and 3.6 other people on average when there is no immunity in a (sub)population, there is a 6 to 14 day period when someone is infectious but not showing symptoms, simple differential equation)

This is applied (messy, political, entangled with desperate economic imperatives) science not systems level software engineering. The basis of science is that independent work by different teams using different methodologies tends (with eddy currents) to converge on something that we can regard as close to truth or reality in some sense. This is not an argument about engineering change orders or which library to use or what code style might be best.

I suspect that there is a lot of 'flood the zone with shit' going on by various kinds of useful idiot.

Re: Sage & onion

Not my field really, but John Carmack worked on the Imperial College model for a bit before the Microsoft people got involved. The quote below comes from a couple of parts of Carmack's twitter thread about the code...

"Before the GitHub team started working on the code it was a single 15k line C file that had been worked on for a decade, and some of the functions looked like they were machine translated from Fortran. There are some tropes about academic code that have grains of truth, but it turned out that it fared a lot better going through the gauntlet of code analysis tools I hit it with than a lot of more modern code. There is something to be said for straightforward C code. Bugs were found and fixed, but generally in paths that weren't enabled or hit."

It is also worth pointing out that the broad ballpark results of the model were similar in general outline to those produced by a team at the London School of Hygiene and Tropical Medicine. They have put a simplified model up as a Web page for educational purposes. You can twiddle around with that and get thoroughly depressed. You need to read the help page and the associated paper to understand how the variables and interventions interact. The point is that these programs are not systems engineering, they are research. We draw some comfort when different research teams using different methodologies, implemented using different tools give broadly similar results.

Finally, it might be worth checking the last paragraph of the article quoted in the parent thread to this. The - no doubt very talented and effective - software engineer who looked at the code seems to have some interesting ideas about how to manage public health which probably lie quite a few standard deviations from the views of the majority in the UK.

Re: And what about the people ...

Those that do have a smartphone and run apps can run this one. Those that don't, won't. Just because this app won't reach 100% of the population doesn't mean we shouldn't bother with it at all (privacy issues aside)

I think that you are basically assuming that the percentage who do/are able to download and use the app are a random sample from the population as a whole in a particular district (I gather the idea is to modulate lockdown/restrictions in specific areas). If that assumption is correct then yes, a percentage will be enough.

However if there is any systematic difference between the set of people who download and successfully use the app and those that don't, then the decisions generated could be less than optimum in an area. You would not know about the mis-match between the data generated from the application and reality for the incubation period + symptoms worsening period, so say 14 to 21 days. If the R from app was 1.05 and the real R was 1.5 (say) that could be a very significant issue

keithpeter
Coat

Re: And what about the people ...

The age distribution of those prepared/able to download and run the app will be skewed away from those most at risk from infection because of the need for an Apple/Android device as mentioned or implied above. This means that the decisions based on the data may not actually be those needed to minimise infection in a given region. (That would be an issue with the Google/Apple api based system as well tbf)

The lack of compatibility between the UK based NHS application and the Rest Of The World Except Australia and Possibly India system may have issues for mutual travel arrangements going forward especially if the UK system is missing a significant number of interactions

And finally, if the system really does miss significant interactions, the data generated will be obviously divorced from the true infection rate in a given postcode - as will become apparent some weeks later (infection/symptom time lag) for each degree of separation in a local graph
