mailx is understimated

Posted on by Paolo Redaelli

From  Linux mailx command help and examples

mailx is an intelligent mail processing system, which has a command syntax reminiscent of ed with lines replaced by messages. It is based on Berkeley Mail 8.1, is intended to provide the functionality of the mail command, and offers extensions for MIME, IMAP, POP3, SMTP, and S/MIME. mailx provides enhanced features for interactive use, such as caching and disconnected operation for IMAP, message threading, scoring, and filtering. It is also usable as a mail batch language, both for sending and receiving mail.

I bet a beer that most of you gravely underestimate the power of the good, old mail command on a GNU/Linux OS, at least.

I did.

Timeo Smart-TV et dona ferentes

Veramente belli ed istruttivi gli appunti di Gabriele Merli come per esempio questo «Windows – Dispositivi fantasma nelle risorse di rete – Gabriele Merli» leggendo i quali rimango sempre più convinto che mai e poi mai una smart-tv entrerà in casa mia.

Beh. a dirla tutta varrebbe anche per tablet e telefonini su cui non gira un sistema libero installato da me, ma almeno quelli li posso chiudere in un cassetto mentre una smart tv è sempre lì, in vista e ben alimentata.

The fairy of compromised servers

I’ve been visited by the fairy of compromised servers!

Otherwise how would you explain mail like this:

From paolo.redaelli@$COMPRIMISED_DOMAIN.it Sat May 13 03:36:49 2017
Envelope-to: paolo@MY_OWN_DOMAIN
Delivery-date: Sat, 13 May 2017 03:36:49 +0200
From: "Paolo Redaelli" <paolo.redaelli@$COMPRIMISED_DOMAIN.it>
To: "Paolo Redaelli" <paolo@MY_DOMAIN>
Subject: =?utf-8?B?4piARnc6IHNvbWUgaW5mbyB0aGF0IG1heSBiZSB1c2VmdWw=?=

If case you’re wondering, no, I’m not that crazy to send emails to myself in the middle of the night with obscure subjects.

I’ve been warned tough by a wise hacker, from her tallest tower in castle far far away, built upon an obscure and dangerous dungeon.

From an IT professional, working in a fashion firm:

The administration/accounting tells us that the IT cost shall be between 0,6-0,8% of revenues.

I shall keep this in mind.

 

KaTeX – The fastest math typesetting library for the web

 KaTeX – The fastest math typesetting library for the web

Type an expression:

See how it renders with KaTeX\KaTeX:
f(x)=∫−∞∞f^(ξ)e2πiξxdξf(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xif(x)=∫​−∞​∞​​​f​^​​(ξ)e​2πiξx​​dξ
Simple API, no dependencies – yet super-fast on all major browsers.
Math typesetting on the web seems to have a new king. Thank you for all the fish, MathJax…
