Re: Maybe...

If you think about all the instances of the Linux kernel operating right now - from phones and embedded devices via servers and network devices in data centres, through to high performance compute clusters, isn't the desktop operating system aspect (i.e. endpoint client) almost of measure zero? Nice to have but it hardly defines the project.

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.

(I still think that Ferguson should release the original file)

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

Have I missed anything?

Re: Been on the receiving end of that

Glad things worked out OK sort of

On the old GCSE Maths modular courses, there was an X code for a missing component on the full results line. That meant either didn't go to the exam or missing bit of coursework, and the other components would show actual grades or scores obtained.

Might be worth trying to get the grades for each separate component of an exam if anyone finds themselves in this situation again.Will tell you what went wrong, and will show good scores for the other components which is a confidence boost to student.

3) student toddles off to physical desk to show ID and sign forms

5) single sign on to most basic systems plus teacher created accounts to a few commercially provided subscription services depending on course
