MakeCode Miro Bit Updated +Created
Microbit simulator using some Microsoft framework.
TODO the Python code from there does not seem to run on the microbit via uflash, because it is not MicroPython.
forum.makecode.com/t/help-understanding-local-build-options/6130 asks how to compile locally and suggests it is possible. Seems to require Yotta, so presumably compiles?
Presumably this is because Microsoft ported their MakeCode thing to the MicroBit, and the Micro Bit foundation accepted them.
E.g. there toggling a LED:
led.toggle(0, 0)
but the code that works locally is a completely differently named API set_pixel:
microbit.display.set_pixel(0, 0, )
Microsoft going all in on adopt extend extinguish from an early age!

Change of basis matrix Updated +Created
The change of basis matrix is the matrix that allows us to express the new basis in an old basis:
Mnemonic is as follows: consider we have an initial basis . Now, we define the new basis in terms of the old basis, e.g.:
which can be written in matrix form as:
and so if we set:
we have:
The usual question then is: given a vector in the new basis, how do we represent it in the old basis?
The answer is that we simply have to calculate the matrix inverse of :
That is the matrix inverse.

CIA 2010 covert communication websites / 2013 DNS census NS records Updated +Created
ns.csv is 57 GB. This file is too massive, working with it is a pain.
We can also cut down the data a lot with stackoverflow.com/questions/1915636/is-there-a-way-to-uniq-by-column/76605540#76605540 and tld filtering:
awk -F, 'BEGIN{OFS=","} { if ($1 != last) { print $1, $3; last = $1; } }' ns.csv | grep -E '\.(com|net|info|org|biz),' > nsu.csv
This brings us down to a much more manageable 3.0 GB, 83 M rows.
Let's just scan it once real quick to start with, since likely nothing will come of this venue:
grep -f <(awk -F, 'NR>1{print $2}' ../media/cia-2010-covert-communication-websites/hits.csv) nsu.csv | tee nsu-hits.csv
cat nsu-hits.csv | csvcut -c 2 | sort | awk -F. '{OFS="."; print $(NF-1), $(NF)}' | sort | uniq -c | sort -k1 -n
As of 267 hits we get:
      1 a2hosting.com
      1 amerinoc.com
      1 ayns.net
      1 dailyrazor.com
      1 domainingdepot.com
      1 easydns.com
      1 frienddns.ru
      1 hostgator.com
      1 kolmic.com
      1 name-services.com
      1 namecity.com
      1 netnames.net
      1 tonsmovies.net
      1 webmailer.de
      2 cashparking.com
     55 worldnic.com
     86 domaincontrol.com
so yeah, most of those are likely going to be humongous just by looking at the names.
The smallest ones by far from the total are: frienddns.ru with only 487 hits, all others quite large or fake hits due to CSV. Did a quick Wayback Machine CDX scanning there but no luck alas.
Let's check the smaller ones:
inews-today.com,2013-08-12T03:14:01,ns1.frienddns.ru
source-commodities.net,2012-12-13T20:58:28,ns1.namecity.com -> fake hit due to grep e-commodities.net
dailynewsandsports.com,2013-08-13T08:36:28,ns3.a2hosting.com
just-kidding-news.com,2012-02-04T07:40:50,jns3.dailyrazor.com
fightwithoutrules.com,2012-11-09T01:17:40,sk.s2.ns1.ns92.kolmic.com
fightwithoutrules.com,2013-07-01T22:46:23,ns1625.ztomy.com
half-court.net,2012-09-10T09:49:15,sk.s2.ns1.ns92.kolmic.com
half-court.net,2013-07-07T00:31:12,ns1621.ztomy.com
Doubt anything will come out of this.
Let's do a bit of counting out of the total:
grep domaincontrol.com ns.csv | awk -F, '{print $1}' | uniq | wc
gives ~20M domain using domaincontrol. Let's see how many domains are in the first place:
awk -F, '{print $1}' ns.csv | uniq | wc
so it accounts for 1/4 of the total.
