GMail cleanup

This Python script cleans All Mail GMail folder by moving emails to Trash if there are more than 33 emails from same sender or email is more than 55 days old (values can be adjusted by editing code). IMAP must be enabled in order to work.

XFCE reboot on Ctrl+Alt+Delete

Exclude the only specific field from django serialization

MyModel._meta.get_field('my_field').serialize = False

Sort Firefox Bookmarks

% sqlite3 ~/.mozilla/firefox/*.default/places.sqlite 'update moz_bookmarks set position=(select count(*) from moz_bookmarks as b where lower(b.title) < lower(moz_bookmarks.title));'

Autologin in FreeBSD without GDM

Autologin and startx without GDM or other display manager:

1. Add this line to /etc/gettytab to describe new terminal line with autologin

   al.username:al=username:tc=std.230400:

   , where <username> is user to log in automatically. "al.username" is the terminal name which can be any.
2. Change ttyv0 line in /dev/ttys from this:

   ttyv0 "/usr/libexec/getty Pc" xterm on secure

   to this

   ttyv0 "/usr/libexec/getty al.username" xterm on secure

   to spawn auto logged in terminal at Alt+F1 console.
3. Set login shell on ttyv0 to start X11 immediately

   echo 'if $tty == ttyv0 startx' >> ~/.login

4. Reboot.
5. X11 will start automatically for <username>.

Django html5lib validating middleware

Django middleware to validate every HTML response with html5lib.

Usage

1. Save to middleware.py
2. Add 'middleware.ProfileMiddleware' to MIDDLEWARE_CLASSES

Listing

from html5lib.html5parser import HTMLParser
from html5lib import treebuilders
from django.http import HttpResponse


class ValidateMiddleware(object):
    def process_request(self, request):
        pass

    def process_response(self, request, response):
        if response.content and 'html' in response['Content-Type'] \
                and 'disable-validation' not in request.GET:
            # validate
            treebuilder = treebuilders.getTreeBuilder("simpleTree")
            parser = HTMLParser(tree=treebuilder, strict=True)
            try:
                parser.parse(response.content)
            except Exception:
                pass
            if parser.errors:

                    for x in range(max(0, row - 3), min(len(lines), row + 1)):

                out = '\n'.join(out)
                return HttpResponse(out, mimetype='text/plain')
        return response

    def process_view(self, request, callback, callback_args, callback_kwargs):
        return callback(request, *callback_args, **callback_kwargs)
