Comment on “Potential Mechanisms for Human Genome Integration of Genetic Code from SARS-CoV-2 mRNA Vaccination”

Even a layperson, such as the author of this commentary, can spot the chunky inconsistency clumps in what [Kyriakopoulos et al., 2022] are serving. The reader is encouraged to put in writing what more can they find in addition to what is mentioned here.

Not all of them

The first red flag should immediately be the fact that one of the credited authors is a "naturopathic oncologist". See [Atwood, 2003], [Atwood, 2004], [Gorski, 2014], [Russell, 2009], [Ernst, 2001], [Wilson et al., 2004], [Busse et al., 2008], [Downey et al., 2010], [Herzog et al., 2013].

Imagine a "metaphysical firefighter" — "Yes, ma'am, what is it?... Your house is on fire?... I'll start meditating right away!"

Why Python dependency management sucks

Lack of a comprehensive official standard tool. "Comprehensive" being the key word here.

Emitting binary from POSIX shell scripts

Different (supposedly) POSIX compliant shell environments yield varied results when asked to emit non-printable characters. But there is one method that works consistently across a wide variety of shells.

Sparked by [this conversation][thread].

OSInt on 2022-03-14 9M79 Tochka-U at Donetsk

The Russian sources claim that the missile was launched by Ukranian forces. The Ukranian sources claim it was a false flag operation by Russians themselves.

This investigation reveals that the former is highly unlikely, as the engine end of the the 9M79 Tochka-U missile, the range of which is up to 120 km, appears to have traveled from the approximate bearing of 148° southeast by south, which falls far within the Donbas territory of Ukraine that the Russian forces siezed in 2014, and exends farther on into Russia, to area near Rostov-on-Don.

The remains of the missile may have been moved by individuals in Donetsk to incriminate Russian forces, but, in addition to the absurdity of tampering with the evidence to shift the blame towards their own side of allegiance (although, never underestimate Russihuman incompetence), there are no visible signs of this being the case.

Geolocating

I think I'll just summarize my findings down here; it didn't all seem obvious and took some googling and tinkering, as some sources are a bit ambiguous on some of the points.

All native: tools.go

The best practice as endorsed by the Go team (golang/go#25922 (comment)).
