Noodverlichting: drijfkaarsjes op zonnebloemolie

Thursday, April 12, 2012 Posted by

Een paar jaar terug kocht ik op een beurs drijfkaarsjes (“Schwimm leuchter”), zie drijfkaarsjes.nl. Dit zijn geen kaarsjes van was, maar plastic schaaltjes die blijven drijven. Het concept is tegelijkertijd elegant, efficient en geniaal.

Enigmail password trouble with OpenPGP

Thursday, April 12, 2012 Posted by

I’m using Thunderbird and Enigmail on Kubuntu, signing all my email and encrypting correspondence whenever possible. Lately (probably due to an update) the password-entry window does not appear. In stead, it complains immediately about:

openpgpg alert - error bad passphrase

I have set the preferences to remember my password for several minutes, so I figured there’s some problem there. I am not using gpg-agent, so EnigMail should fall back to the default.

Checking OpenPGP > Debugging Options > View Console shows what Enigmail is doing. I type my message (signing option checked) and click Send. The console shows:

gpg: gpg-agent is not available in this session
gpg: can't query passphrase in batch mode

Which makes sense, I am not using gpg-agent. Finally, it complains:

gpg; [stdin]: clearsign failed: bad passphrase

And gives up. Googling around I find similar problems, but no solution. Then I noted the following line in the console:

gpg: NOTE: old default options file '~/.gnupg/options' ignored

The ‘options’ file has been obsoleted, gnupg uses gpg.conf now. I checked, indeed the contents of ‘options’ are also present in gpg.conf. Moving ‘options’ away and restarting Thunderbird solved the problem.

Moreover, it also solved my password problem, I now get the password prompt and can happily sign my email.

Viper UBAC Special Operations Shirt

Saturday, April 7, 2012 Posted by

With the advent and wide-spread use of body armour came a new type of shirt: the Under Body Armour Clothing or UBAC for short. The idea is simple; if you’ll be wearing a vest it may not always be comfortable to wear it overtop your normal shirt or jacket. So the solution is simple: an undershirt with sturdy sleeves.

5.11 Sabre 2.0 – numerous improvements!

Saturday, April 7, 2012 Posted by

Years ago I bought a 5.11 Sabre Jacket, which I reviewed here. Now 5.11 has updated their Sabre into the Sabre 2.0. Normally, with software an update in version number does not necessarily mean the actual product has become better. However, the Sabre 2.0 compares well to the original and is a great improvement on a great jacket. Read the rest of this entry »

Exchange Webmail 2010 and OpenPGP Signed mail

Tuesday, March 20, 2012 Posted by

I am a long-time user of OpenPGP to digitally sign my email. I am aware of the fact that most mail clients do not support this by default (but installing the EnigMail addon in Thunderbird couldn’t be easier).

Most mail clients simply show the mail, with my signature as attachment. No hurt done, they can still read my email message. Now, microSoft Exchange Webmail 2010 has a new feature and gives the following error:

“This message has a digital signature. The digital signature couldn’t be validated because the S/MIME control isn’t available.”

And decides this is a reason to not show the contents of the email. PANIC!

But have no fear, there’s yet another typical microsoft feature here: click “Reply” and you’ll see the contents of the email as quoted text.

They never seize to amaze me.

Why sign email you wonder? Read this article.
