Firefox and related tabs

New version of Firefox (you did upgrade to 3.6 already, right?) now opens new tabs immediately adjacent to the tab you’re in when you right-click a link. To change it back to the “old” way (open a new tab after all the other tabs), go to about:config in the URL bar and toggle browser.tabs.insertRelatedAfterCurrent from “true” to “false”

Fighting tyranny

“Still, if you will not fight for the right when you can easily win without bloodshed; if you will not fight when your victory will be sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves.” — Winston Churchill

“Miracles do not cluster. Hold on to the Constitution of the United States of America and the Republic for which it stands — what has happened once in six thousand years may never happen again. Hold on to your Constitution, for if the American Constitution shall fail there will be anarchy throughout the world.” — Daniel Webster

Removing Picasa “Favorite Activity”

Some random person on Picasa shared an album with me. I have no idea who they are or why they shared with me. Some random travel pictures of Malaysia or something. But it was irritating to have to see it in “Favorites Activity” every time I went into my own albums.

Google doesn’t provide a direct way from the activity list to remove someone. The process to remove it is to click the shared link and go to the other person’s gallery. Add them as a Favorite using the link on their album.

Then when you go back to your own People/Favorites tab, and click the “List” link in the top right corner, there are checkboxes to stop getting updates from them or to remove them outright.

Keyboard mapping problem in Ubuntu VNC session

New hard drive in my home PC = upgrade to/new install of Ubuntu 9.10 last night.

I set up tightvncserver and all worked fine from home when I tested it last night. Today from my Macbook at work, though, odd keyboard mapping prevented using a VNC session.

A little searching online reveals that tightvncserver is apparently built with an old version of XFree. Removing tightvncserver and using vnc4server instead solved the problem.


“Interest never sleeps nor sickens nor dies; it never goes to the hospital; it works on Sundays and holidays; it never takes a vacation; it never visits nor travels; it takes no pleasure; it is never laid off work nor discharged from employment; it never works on reduced hours; it never has short crops nor droughts; it never pays taxes; it buys no food; it wears no clothes; it is unhoused and without home and so has no repairs, no replacements, no shingling, plumbing, painting, or whitewashing; it has neither wife, children, father, mother, nor kinfolk to watch over and care for; it has no expense of living; it has neither weddings nor births nor deaths; it has no love, no sympathy; it is as hard and soulless as a granite cliff. Once in debt, interest is your companion every minute of the day and night; you cannot shun it or slip away from it; you cannot dismiss it; it yields neither to entreaties, demands, or orders; and whenever you get in its way or cross its course or fail to meet its demands, it crushes you.”  — J. Reuben Clark

Removing Mailman list members with invalid addresses

If you have a list member with an invalid address (I ended up with one that had 2 concatenated addresses, yielding 2 @ characters which the default parser apparently does not like), the regular bin/remove_members script won’t work. You can use this trick though:

cd /path/to/mailman
bin/withlist -l listname
>>> m.removeMember('')
>>> m.Save()
>>> ^D

See the Mailman wiki for more details and other things to try if even this step doesn’t work.

Deleting sendmail file pairs based on content

This one-liner will identify files containing a string, and then use some bash string manipulation to generate a wildcard for the pair of files sendmail creates for each message (dfn for message content, and Qfn for headers). This assumes you’re running it in the mail queue directory (/var/spool/mqueue for example).

for f in `grep -l -i viagra *`; do t=${f:10:6}; rm -f *${t}; done

The ${f:10:6} extracts the last 6 characters of the filename, then the rm command prepends that with the wildcard.

Some sample output:

[root@mail mqueue]# grep -l -i cialis *

But there are actually six files:

[root@mail mqueue]# ls -l | egrep "020530|015512|031687"
-rw------- 1 root smmsp 2062 Aug 30 01:27 dfn7U8Rc3X020530
-rw------- 1 root smmsp 2232 Aug 30 06:07 dfn7UD7BUh015512
-rw------- 1 root smmsp 2069 Aug 31 07:21 dfn7VELCbV031687
-rw------- 1 root smmsp 825 Aug 30 01:27 Qfn7U8Rc3X020530
-rw------- 1 root smmsp 837 Aug 30 06:07 Qfn7UD7BUh015512
-rw------- 1 root smmsp 810 Aug 31 07:21 Qfn7VELCbV031687

So we run the command, using cialis:

for f in `grep -l -i cialis *`; do t=${f:10:6}; rm -f *${t}; done

Then there are no more files 🙂

[root@mail mqueue]# for f in `grep -l -i cialis *`; do t=${f:10:6}; rm -f *${t}; done
[root@mail mqueue]# grep -l -i cialis *
[root@mail mqueue]#
