Converting HTML mail via procmail

All the procmail recipes I found on a quick search failed to handle quoted-printable HTML encodings, regularly used everywhere. And those that had quoted-printable examples used tools no longer maintained - such as mimencode.

The solution is to use Perl directly:

* ^Content-Type: text/html;
* ^Content-Transfer-Encoding: *quoted-printable
| perl -pe 'use MIME::QuotedPrint; $_=MIME::QuotedPrint::decode($_);'
| lynx -dump -force_html -stdin
| formail -i "Content-Type: text/plain; charset=us-ascii"

Ripping vinyl on Linux

 I've been ripping a lot of stuff from vinyl to FLAC recently. Here's how I do it.

I have an Alesis I/O 2, which works well and seems fairly decent quality.

First, most important, step, is to stop trying to use Audacity. It's incredibly broken and unreliable. Go get ocenaudio instead. It's fairly new, but it works reliably.

After monitoring your levels, record the whole thing into ocenaudio.

First trim any obviously loud clicks such as when landing the needle. ocenaudio doesn't seem to have a "draw sample" function yet, the only thing I miss from Audacity, but deleting just a few samples is usually fine.

Normalise everything.

Then select a whole track using Shift-arrows (and Control to go faster). Press Control-K to convert it into a region, and name it if you like.
You'll see references to using zero-crossing finders to split tracks. This is always a bad idea - it's simply not reliable enough, especially with an old crackly record, isopropyl'd or not.

Zoom all the way out again, make sure the number of tracks is right.

Then File->Export Audio From Regions, making sure that the "separate files" checkbox is set.

Now it's tagging time: run "kid3 yourdirwithflacs". First import from discogs, presuming it has the release (it usually will) File->Import From Discogs. Then click 'Tag 2' in the Format Up part, along with the format you need. Save all those, then use Tools->Rename Directory to rename the containing directory. You're done.

Recording on Linux with Alesis io|2

A little note for myself: to get low-latency monitoring, and more importantly, record at the right rate, you need to set the Configuration-Profile to "Digital Stereo Input" in pavucontrol!

Update: you also need this in ~/.pulse/daemon.conf :


Another update: PA/ALSA often seems to forget the sensible default devices, and ocenaudio starts
trying to record from the monitor devices. Solution seems to be to run pavucontrol, start ocenaudio recording, and change the drop down box to select io|2 Digital Stereo.

PayPal idiocy

This is unbelievably stupid of Paypal. I just got this email from them:

vinyl tap records would like you to use PayPal - the safer, easier way to pay and get paid online.
To send vinyl tap records your payment and see the details of this invoice, copy and paste this link into your web browser:

So much for "never click a URL in email". Even worse, if you log in separately, the request is not visible anywhere. Morons.

NatWest phishing service

I got some NatWest phishing spam the other day and was amused to notice this:

<title>NatWest - Security Information</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<link rel="stylesheet" type="text/css" href="" media="all" />
<a href=""><img src="" alt="NatWest - Load home page" /></a>

Enterprising of them to actually uses NatWest's explanation of phishing to ... phish.
