CIA 2010 covert communication websites / JS CDX scanning Updated +Created
JAR, SWF and CGI-bin scanning by path only is fine, since there are relatively few of those. But .js scanning by path only is too broad.
One option would be to filter out by size, an information that is contained on the CDX. Let's check typical ones:
grep -f <(jq -r '.[]|select(select(.comms)|.comms|test("\\.js"))|.host' ../media/cia-2010-covert-communication-websites/hits.json) out | out.jshits.cdx
sort -n -k7 out.jshits.cdx
Ignoring some obvious unrelated non-comms files visually we get a range of about 2732 to 3632:
net,hollywoodscreen)/current.js 20110106082232 http://hollywoodscreen.net/current.js text/javascript 200 XY5NHVW7UMFS3WSKPXLOQ5DJA34POXMV 2732
com,amishkanews)/amishkanewss.js 20110208032713 http://amishkanews.com/amishkanewss.js text/javascript 200 S5ZWJ53JFSLUSJVXBBA3NBJXNYLNCI4E 3632
This ignores the obviously atypical JavaScript with SHAs from iranfootballsource, and the particularly small old menu.js from cutabovenews.com, which we embed into cia-2010-covert-communication-websites/cdx-post-js.sh.
The size helps a bit, but it's not insanely good unfortunately, only about 3x, these are some common JS sizes right there!
Ciro Santilli's cheapness Updated +Created
When Ciro was a teenager, he was extremely cheap e.g. for clothes, food and video games even tough his family didn't have bad financial conditions.
This was mostly to save the world by not wasting resources that other people in need could use, and to save money so he could have more money to do more of whatever he wanted without the obligation to work.
But Ciro admits that shocking people with the incredible level of low quality goods was also fun.
Ciro changed after he came to Europe, especially in regards to food, perhaps corrupted by the fact that now the best chocolates, cheeses and breads in the world were not much more expensive than the cheapest brand you could buy. He still hates clothes that are just to look good like costumes though.
Living close to a small favela, São Remo, the favela next to USP, helped Ciro get frighteningly cheap goods on the shop frequented by the favela neighbours.
One legendary story is that of when his flatmate dropped some past on the kitchen floor, and the bowl broke, but Ciro prevented the flatmate from throwing it away and ate some of it nevertheless. What spooked them out the most was Ciro's statement that the pasta now had a crunchy glass shard texture to it.

Overdetermination of Maxwell's equations Updated +Created
As seen from explicit scalar form of the Maxwell's equations, this expands to 8 equations, so the question arises if the system is over-determined because it only has 6 functions to be determined.
As explained on the Wikipedia page however, this is not the case, because if the first two equations hold for the initial condition, then the othe six equations imply that they also hold for all time, so they can be essentially omitted.
It is also worth noting that the first two equations don't involve time derivatives. Therefore, they can be seen as spacial constraints.
TODO: the electric field and magnetic field can be expressed in terms of the electric potential and magnetic vector potential. So then we only need 4 variables?
Oxford Updated +Created
The city clearly exists because it is in the confluence of the river Thames and the River Cherwell. In such confluences, terrain tends to be flat, and fords are also common, with crossings wide and shallow, and so it was an important crossing place.
Notably, the River Cherwell is a natural link between London and the North towards Coventry, and then Birmingham, as it, and then the Thames in which it goes into, puncture through both the Chilterns, then North Essex Downs and the Cotswolds hills. The M40.

How to teach / Publish somewhere people can comment Updated +Created
Then, if people find errors, or have questions, they will write a comment near the content itself.
Then, next person that comes along and has the same problem, will also find that comment, and your answer will solve their problems too.
The perfect way to do this is to use GitHub issues

This is basically what Jimmy Wales had originally set out to make Wikipedia, a peer reviewed thing.
But then he noticed the entry barrier was too high while inviding an economist to review an article he wrote, and just made the more open thing instead.
