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?

By Arnon Weinberg, on October 25th, 2017 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
By Arnon Weinberg, on January 31st, 2015 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:

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
By Arnon Weinberg, on June 25th, 2014 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)”
By Arnon Weinberg, on March 28th, 2014 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
