JackeJR··on Experts warn Letby inquiry of misreading stats to explain 'suspicious' deaths
The expert statistical analysis alluded to is simply the framework for causal inference. Had Letby not been on duty for a similar group of patients, would the number of patients who had died been the same?

If the answer is no, then a follow on question regarding whether or not factors associated with Letby could have resulted in the deaths rather than Letby herself. This could be a fellow worker who always worked in tandem with her etc.

Finding the appropriate set of data and applying statistical techniques for this is not trivial hence the expert mention.

I also see smoking, alcohol and gambling destroy families yet they are all legal in Singapore. Heck, they even built not 1 but 2 casinos in recent years.

JackeJR··on Twitter applies 7-day suspension to half a dozen journalists
I think this is maybe in reference to LBJ's lifelong biographer Robert Caro where he states that "power does not corrupt, power reveals". In it he asserts that what one does with power after obtaining it reveals what the person is. It was there all along, power simply makes it show up prominently.
JackeJR··on Hong Kong: Police Raid Tiananmen Square Museum
I agree that once the growth slows China will start to see cracks in its society. This, I submit, is the reason why Beijing is doubling down on the nationalist path. Cast the West as the enemy and China as the victim of oppression to drum up nationalist sentiments.

The social compact I believe that exists in China is that the people put up with the curbs either out of ignorance of the lacks of curbs or because of the promise of a better life which comes along with increased job wages as long as they toe the party line.

The moment the bargain is not held up for the increased wages, the compact starts to get eroded. Turmoil in China if it happens will have a widespread and largely unknown consequences. Unknown because too many pieces are intricately linked to the stable functioning of China.

For one, I hope to be able to witness this one day.

JackeJR··on Hong Kong: Police Raid Tiananmen Square Museum
Some think that if the US extended their protection to Taiwan, Beijing would not attempt to take Taiwan.

Let's just assume for a moment that the US will fight off attacks by China to take Taiwan. And that US successfully ward off an attack. What next? What is there to prevent China from trying again and again and again? Will the US be prepared to ward off attacks after attacks after attacks? This is unlikely to happen.

With this, lets again assume that China eventually successfully takes Taiwan. What next? They would have taken over an island with a large number of people who resents their rule. There will be a persistent resistance group as long as Beijing continues her ways and Beijing is aware of this and is trying to shape the education of the younger generations so that the resentment does not cross generations.

Even if all these were to take place and all hope seems to be lost. There is a glimmer of hope. A totalitarian state has one major fault. There is no effective feedback mechanism and to assume that this one man can make the right call, the right decision all the time is a stretch. At some point, be it internal infighting, or a policy misstep creating intense misery amongst the people, there will be discontent and if the history of China is any indication, the discontent can trigger uprisings and eventually a change of regime.

The only way the regime can be changed is from the inside.

JackeJR··on Apple enabling client-side CSAM scanning on iPhone tomorrow
Sure. And as I mentioned, there will be screw ups along the way. As with any new capability/tech be it nuclear power or recombinant DNA or ability to locate CP, there can be legitimate uses that we can rally behind and ways for them to be abused.

Checks and balances are never a done deal. If we reject checks and balances and as a result reject new tech because of abuse potential, how then should we as a civilisation advance?

JackeJR··on Apple enabling client-side CSAM scanning on iPhone tomorrow
The slippery slope argument is that the use of this method on private files, i.e. not shared with others except for the service provider can legitimise the expansion of such scamming scopes.

While this argument can and have indeed happened in other instances, this is akin to saying that we should not give anyone any powers to do anything because it is a slippery slope that they can use it to do bad things.

What then sets out the difference between what a slippery slope and a non-slippery one is? Checks and balances and the history of USA have shown that this is indeed what can reign in the worst instincts of any single entity. History of course have also shown when these failed and these should serve not as a reason to reject the idea of checks and balances but as acknowledging it's imperfection and think of ways to mitigate it.

Going by the what is implied, it stands to reason that everything is meaningless except for those that represents or aids in a significant improvement in our lives or change our fate as a human race.

This is neglecting how these developments came to be. We don't know when Einstein was born that he will go on to discover a world changing equation and theorem. If we don't give diversity such as these minority languages to thrive, we may simply be creating an environment that is so sterile and constant that any new innovations have little chance of happening from a lack of stimulation.

JackeJR··on Is carbon capture a viable solution?
Assuming that we WILL expend more energy to capture the carbon, the path to make carbon capture viable is clear: A source of energy that does not add more carbon to the atmosphere.

And existing technologies such as nuclear fission already offers us abundance of energy to do this. The problem is one of scale (how widespread?), acceptability (where can we do this?), cost (who pays?) and time (how soon?).

JackeJR··on Some school districts plan to end the year early, call remote learning too tough
My experience in learning math is that the textbooks try to provide what is right. And what is right typically becomes excessively verbose to the point that the main idea gets lost in the rightness. This is what in person coaching gets you. You get the intuition of the idea, ignoring all the nitty gritty and only when you have a firm grasp of the intuition do you explore what this intuition also means for different cases and hence the nitty gritties.

Having experienced this myself many times over, I now know exactly what to look for in a book when I am self learning. I don't know how this skill is to be taught but if remote learning was to succeed, different methods of learning needs to be outlined and taught to the students and get them to learn to select one appropriate for their learning styles and subject.

JackeJR··on Covid-19’s stop-gap solution until vaccines and antivirals are ready
I too share a dim view of the world's ability to work together. Even now when faced with such a disease that is essentially everyone's problem, countries first and foremost chose to safeguard their own interests at the expense of others. It is a situation where if we survive, we did so because we worked together and if we die, it is because we only cared for ourselves and nobody else. If course this is oversimplifying a very complex interplay of things but my drift is that no country seems to be able to look beyond their borders and see that if we were to win this, we have to work together.

Even more dismaying is the refusal to lift sanctions on Iran. Even a narrowly crafted exception to the sanctions for supplies needed to combat the onslaught of the virus would be good but so far nothing. This is according to what I have read this far and if this is in error, I would be happy to be shown that.

JackeJR··on Keeping the coronavirus from infecting healthcare workers
I don't think the parent's point was that we ignore evidence but that in the absence of evidence (as opposed to evidence suggesting the contrary), we should use priors to guide what we do. In this case, while there are no double blind randomised studies that suggest that widespread mask use reduces R0, priors tell us that masks use protect against infection in other settings.

If we were to weigh the priors, the existing evidence would be leaving towards mask use having a protective effect. The question that we should ask ourselves is, what if the reality turns out to be different? There are 2 scenarios. First, mask use is harmful and the second, mask use has no effect on transmission. The first is very unlikely given what we know and the second will mean that if mask use is encouraged, it will be wasted resources for no gain. If these resources that were wasted were easily obtainable i.e. masks made of old clothing etc, then the downsides aren't serious at all but could have very good upsides if the priors were right.

So I agree, that we should encourage widespread home-made masks use and leave the disposable ones to the healthcare workers.

JackeJR··on Coronavirus: the second-weirdest solution?
For one, fear is irrational. It is based on a perception of threat and we as humans do it in many ways. One way is to see that others are afraid and therefore we should too. To add to this, the fear is not entirely unfounded. Estimates of the fatality are between 1% to 4%. No proper case fatality statistics can be computed as the epidemic is not over/have not gone long enough yet. At 1%, this is already 10 times the fatality rate of the seasonal flu so no, this is not just a bad flu season. This is an exceptionally bad flu season.

The reason I think countries are still trying to contain it is because if we allow the this flu strain to become seasonal because of lack of containment, it becomes an ongoing price that we have to pay each year. Within each new strain of flu that we encounter in the future, if we successively fail to contain each one, there will be many more strains of flu seasonally. Of course, a technological breakthrough may alter such a course.

JackeJR··on Toshiba device tests cancer types from a drop of blood
Not exactly. What Theranos has done is to make clear in its aftermath why the problem of making a diagnosis from a single drop of blood is difficult. In short, the sample size is too small and may not contain biomarkers of the diseases of interest even if they are present in the body. Unless this advancement in its application can show how and why this is not a problem, there will be resistance towards accepting what is being put out without further substantiating evidence.
JackeJR··on BBC News launches 'dark web' Tor mirror
If you have installed tor on your local machine, you can use an add on like proxyswitch omega (firefox and chrome) to redirect all onion websites.

For a network wide approach, you will need to set up PAC and a network accessible tor proxy. The PAC would have a rule that redirects all .onion hosts to the network accessible tor proxy.

JackeJR··on Microsoft has removed the “use offline account” option when installing Windows
The first time Windows update created the spike in CPU, the "fix" was to restore the cache used by Cortana at "%USERPROFILE%\AppData\Local\Packages\Microsoft.Windows.Cortana_cw5n1h2txyewy\LocalCache"

Come the 2nd update that borked the start menu, I suspected that it might be because I restored the cache and so the "fix" was not applying correctly. I then proceeded to wipe the cache altogether and it simply rebuilt itself.

Protip: If trying to delete files using windows built in tools throw up errors (mostly permissions related. this will not help you delete a file whose file handle is locked though.), trying using rm from cygwin. Works every single time.
