Were early travel bans effective against the spread of Covid-19?

Evidence from previous pandemics, and early simulations generated after the beginning of the 2020 coronavirus pandemic, suggested that travel bans are a common political tool for alleviating public anxieties, but have only limited effect in delaying international spread of the Covid-19 virus. However, other models projected that travel bans could be highly effective. As . . . → Read More: Were early travel bans effective against the spread of Covid-19?

Thunderbird: Highlight row on focus

I use the keyboard a lot. For many years now, Thunderbird’s default theme (probably inherited from the desktop, which does the same thing on many dialogues) has had a little quirk that is slightly less conducive to keyboard use: It does not highlight the row with focus. Here is an example:

This way, I . . . → Read More: Thunderbird: Highlight row on focus

https and the browser conspiracy

While Google promotes HTTPS Everywhere, browsers have been working with a certifying authority oligopoly for many years promoting and enforcing an industry based on perception.

https: The good and the bad

The ‘s’ in https stands for ‘secure’ and indicates use of the SSL or TLS protocol. The SSL protocol serves 2 primary purposes:

The Introspection Illusion

 

Decision Awareness

In the early 1980s, Benjamin Libet, a neuroscientist at the University of California in San Francisco, conducted a series of pioneering experiments designed to study properties of conscious awareness. By this time it was already known that signals from the motor cortex region of the brain travel through the nervous system to . . . → Read More: The Introspection Illusion

HTTP DDoS: “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)”

Our servers were attacked recently by a constant stream of HTTP POST requests. The requests were coming in from a large range of IP addresses, at a rate of about 5-10 per second, with random POST data. However, all the requests had the same UserAgent, they always accessed the non-www form of the same domain, . . . → Read More: HTTP DDoS: “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)”

Shell escaping in Perl

Shell Escaping:

There are several methods for escaping special characters in the Linux shell:

Double quotes: Double-quoted strings require escaping of only a few characters. Example: >echo “Some String: &>|\”\$’\`\s\\” Some String: &>|”$’`\s\ This method is useful as long as the string contains few or no characters that are special to the shell. It also . . . → Read More: Shell escaping in Perl
