For the last weeks/months, I had issues when sending email through my Yahoo mailbox, using Thunderbird…
Not through other mailbox providers
Not using Yahoo webmail
Symptom: UTF-8 incorrect handling. Strange characters (%?…) in the mail body…
Not sure why, but something went wrong on Yahoo side (SMTP servers config I guess)
How to solve it ?
Here are my findings (tested on Windows and on Linux)

I’ve been using Enpass for a while now.
Enpass is a passwords manager, that works fine on desktops running Windows / Linux / Mac, and perfectly integrated with my browser (Firefox,…). It also works on Android and IOS, which makes it really convenient for day-to-day usage…
I may create a special post just to explain why you must use a tool such as Enpass to store your passwords, and why did I chose Enpass (commercial license => you have to pay on mobile devices / but it’s free -like in free beer- on desktops)
I’ve got it installed on all my devices (Linux, Windows, Android phone, Android Tablet,…), as well as for my whole family.
Enpass recently migrated to version 6.x. Among several major changes, one was very expected on my side : multi-vaults…
This means you can create separate vaults to store your passwords, and share some of them with others… I was waiting for it to share many passwords with my wife (on-line shops, government agencies,…)
I managed to do it properly, but you need to know how to configure things.
Here is how I proceeded…

I was recently requested to transform a slideset (originally generated with LibreOffice, but shared as PDF), into a set of images.
This is very simple, using Imagemagick program : convert
The question is : how ? Continue reading “How to extract pages from a PDF as a set of images ?” »
OwnCloud is really a terrific program.
I use it for many purposes, among which, of course, storing files that I can access from anywhere.
I faced a simple, but not trivial issue : I had a lot of files to move to my Cloud repository, already available on my server, and I didn’t want to go through the web interface or the webdav access (unnecessary bandwidth usage). I simply wanted to “move” them from directories, using Unix command line interface.
This is not straight forward, but not difficult either. Here is how I proceeded:

I recently installed Let’s Encrypt mechanism on some of my sites.
Currently, the upgrade is not automatic (beta version + I personally need to be convinced 🙂 )
So, I need to monitor the validity dates of the certificates.
Here is a one-liner that do the job:
echo | openssl s_client -connect <site>:<port> 2>/dev/null | openssl x509 -noout -enddate
Note that I added the initial “echo”, as the openssl is waiting for an input…
$ echo | openssl s_client -connect raistlin.alphamaths.fr:443 2>/dev/null | openssl x509 -noout -enddate

You can imagine any kind of monitoring / notification on top of that !
