pipelines: Diomidis Spinellis blog: Was Knuth Really Framed by Jon Bentley?
by Rodney Brown 29 Feb '20

https://www.spinellis.gr/blog/20200225/ Recently, the formal methods specialist Hillel Wayne <https://www.hillelwayne.com/about/> posted an interesting article <https://buttondown.email/hillelwayne/archive/donald-knuth-was-framed/> discussing whether Donald Knuth was actually framed when Jon Bentley asked him to demonstrate literate programming <https://en.wikipedia.org/wiki/Literate_programming#Critique>. (Knuth came up with an 8-page long monolithic listing, whereas in a critique Doug McIlroy provided a six line shell script.) .... worth reading.

SpamAssassin questions
by Russell Coker 21 Feb '20

Does anyone know of a good Australian whitelist of domains that are totally legit but trigger SA checks? For example seek.com.au triggers checks about lots of money but I want a job paying lots of money. Is there a way of configuring SA to have a per-user Bayes path for virtual mailboxes? EG mail is stored under /mail/$DOMAIN/$USER and I want Bayes under /bayes/$DOMAIN/$USER but there is no entry in /etc/passwd for the user. Why does the command "spamc -d 127.0.0.1 -c -u russell(a)coker.com.au < msg.txt" give a spam score way different from that which was generated when the mail was received? Seems that running spamc from the command-line gives different checks than when it's run by spamass-milter. https://wiki.debian.org/DebianSpamAssassin What's the pros and cons of SA as a Postfix content_filter vs spamass-milter? Prior to reading the above page I never realised that there was any way other than spamass-milter (which seems to work ok for me). What's up with the files like /etc/spamassassin/v340.pre /etc/spamassassin/ v341.pre /etc/spamassassin/v342.pre on Debian? Why are config items split out by SA version? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

log analysis

Whats a good FOSS log analysis system? I'm after something that will aggregate the logs of multiple systems and give results on demand through a web interface and allow alerts to be propagated to a monitoring system. Also what's a good FOSS system for graphing all the metrics of a system (network use, disk IO, CPU use, and arbitrary other metrics? Ideally I'd like something like what Datadog does with a web interface that shows multiple graphs and allows easy comparing of the values from multiple graphs at the same point in time. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
