tDCS day 1

Having bought the v2 developer edition 3 months ago, I have to say I was a little bit scared to try it out. Hadn’t done extensive enough research on all what is known about its effects, positioning or safety to confidently experiment with it.

PSX_20151017_181622Today I decided to finally finish the measuring of the scalp, quite a bit difficult to be precise if done alone. Peeled and placed the moovs hydrogel pads anode on F3 (DLPFC) and cathode on FP2 (supraorbital) as suggested by plenty of research (i.e. ) and started the gamer mode (tDCS, 1.5mA, 10mins, 20V.) in the v2.

I have to say I was feeling quite excited to have them on, like playing with a new toy I have to say. Concluded the session and since I’ve read that sessions go for 10~20 minutes, decided to go for another 10 minutes even though the device warned me not to.

The first session was quite comfortable and enjoyable. Just a bit of tingling of the electricity evenly distributed on the pads. Several times as I pressed on the electrodes with my hands to make sure that the pads were making full contact I saw small bursts of light or phosphenes. I realized that every time I did that the v2 cut the flow of electricity as a measure of safety. For the last 2 minutes of the second session I started to feel a bit uncomfortable but just soldiered on.

After I removed them, checked my skin to see of there was anything different; there was not, checked the pads to see if they were still sticky; they were and packed everything away neatly, I felt some sense of sadness. Not really sure why. Will have to set up a schedule sessions probably every two days and see if there’s any changes in my mood.

Mood is a approximation of how I’m feeling based on the Get’Appy app for Android on a scale of 1 to 22. 1 feeling depressed and 22 feeling joy.

Mood before session : 16:16 -> Contentment (16)

Mood after session : 17:57 -> Pessimism (14)

Obviously this doesn’t mean anything at all, since I can’t really tell my mood from moment to moment precisely, and only infer my mood based on cues.

Thus I have to say, just wanting to write about the experience is good enough cue that at least it was exciting.

Aspie Quiz

I did a new aspie quiz as of today. Interestingly the results seems to follow the exact same pattern as the last time I did the same test two years ago. This I find to be very revealing.

Your Aspie score: 84 of 200
Your neurotypical (non-autistic) score: 122 of 200
You are very likely neurotypical

Your Aspie score: 106 of 200
Your neurotypical (non-autistic) score: 87 of 200
You seem to have both Aspie and neurotypical traits

On god.

“The fact that the universe is more remarkable than the fairy tales that were talked about by bronze age illiterate peasants before we knew the earth orbited the sun… we should celebrate… there’s no need for god” – Lawrence M. Krauss

Exherbo git commit workflow

This is the workflow I used successfuly to properly modify and send to Exherbo for review my first commit which was a version bump of feh.

.- Modify the proper repository under /etc/paludis/repositories/ by adding sync = git:// local: git+file:///home/mercurytoxic/repos/rbrown to the required conf file

.- Make a local directory to act as repository mkdir /home/mercurytoxic/repos

.- Git clone to local with git clone git://

.- Modify the exheres needed located in /home/mercurytoxic/repos/rbrown…

.- Commit with git commit -a

.- sync sudo cave sync -s local rbrown and test sudo cave resolve -x1 feh

.- Modify/Commit again until everything is perfect

.- Reduce all commits to just one with git rebase -i

.- Create patch, format it and pastebin it with git format-patch --stdout -M -C -C -1 | wgetpaste -r

.- Submit the patch to #exherbo in freenode as !pq ::rbrown

Yubikey + Roundcube mail = Two factor authentication webmail client

Second time updating roundcube mail to support OTP with yubikey. Process was fairly simple following instructions in

Install the code from

Add to config/

$rcmail_config['plugins'] = array('yubikey_authentication');

Add to plugins/yubikey_authentication/ and set the id and API key from Yubico:
$rcmail_config['yubikey_api_id'] = '';
$rcmail_config['yubikey_api_key'] = '';

Then, within roundcube webmail, in each user you can select if you want to set up a yubikey or not under settings.

Voilà, two factor authentication webmail

SSL LABS has a SSL server test, checking on it made me realize it wasn’t doing too bad but there was some room for improvement. Overall rating was 64 “C”. Scored 100 except on protocol support, because I was still using SSL v2, which is deemed insecure and 40 in key exchange.

First step is to modify to protocol support, for that I changed the httpd-ssl.conf file to:

#By Luis Aranguren 2011-12-12 suggestions/test

Thus removing the SSLv2 support with !SSLv2 and removing all low strength ciphers with !LOW. Just those two changes increase my score to 85 “A”. With protocol support to 85 and Key Exchange to 80. This only removed the ciphers from the protocol and not the protocol itself, so I need to add the following to the same file:

SSLProtocol ALL -SSLv2

This removed the protocol, but did not improve the score.

Torrage + Apache

A while ago I tried to install Torrage with Apache and not the suggested lighthttpd. I had to modify the suggested “README-lighttpd.txt” in the docs directory to suit an apache .htaccess in the main folder.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^$
RewriteRule ^torrent/([0-9A-F]{2,2})([0-9A-F]{2,2})([0-9A-F]{36,36}).* /t/$1/$2/$3.torrent [R=301,L]
<FilesMatch "\.torrent">
Header set Content-Encoding "gzip"

<FilesMatch "\.ghtml">
Header set Content-Encoding "gzip"

This definitely did the trick and got Torrage working flawlessly with Apache.
