Open letter to Donald Trump

I signed the Global Open Letter to Donald Trump which says:

Dear Mr. Trump,

This is not what greatness looks like.

The world rejects your fear, hate-mongering, and bigotry. We reject your support for torture, your calls for murdering civilians, and your general encouragement of violence. We reject your denigration of women, Muslims, Mexicans, and millions of others who don’t look like you, talk like you, or pray to the same god as you.

Facing your fear we choose compassion. Hearing your despair we choose hope. Seeing your ignorance we choose understanding.

As citizens of the world, we stand united against your brand of division.

Luc Saffre

I also join the hopes and warnings expressed in the statement of Archbishop Joseph E. Kurtz of Louisville, Kentucky.

Let’s pray:

  • May our politicians propagate the values of compassion, hope, love for our ennemies, and unity of humans.

  • May our polititians have the courage to learn, to grow in spirit and to change their convictions where needed.

  • Let us see the face of God in our neighbors, especially the suffering or those with whom we may disagree.

Desktop notifications

I merged Hamza’s work on #923 into The lino package (the channels branch).

Applications with lino.modlib.notify now use Tyler Nickerson’s the Push.js library for displaying “desktop notifications” instead of plain JavaScript “alert” messages.

My own mail server

It is already more than a week that refuses to talk to the postfix on when it tries to relay an outbound mail:

host[] refused to talk to me:
554 5.7.1 <unknown[]>: Client host rejected: Access denied

Now I started to convert into a stand-alone mail server

Excerpts of my /etc/postfix/ file:

# relayhost =

# LS 20161111
# Alternative 1: don't relay mail from other hosts.
mynetworks_style = host
relay_domains =

Now of course the situation changed. The other side still refuses to talk to me, but now it is, and they give an explanation which I can understand:

Nov 11 13:06:30 vps postfix/smtp[1281]: 761A82A684F:
delay=1.3, delays=0.08/0.01/1.2/0, dsn=4.0.0, status=deferred (host[] refused to talk to me:
(mxgmx005) Nemesis ESMTP Service not available 554-No SMTP service
554 invalid DNS PTR resource record, IP=

Yes, this is my problem:

$ host
Host not found: 3(NXDOMAIN)

I must setup a correct reverse DNS zone. How to setup Reverse DNS and PTR records

Desktop notifications continued

Hamza and I played around and discussed about desktop notifications.

  • Messages should no longer automatically get marked as seen as soon as they are displayed by the browser (because the user might be away from their computer).

  • The current behaviour when clicking a desktop notification is to focus the browser window. That’s perfect.

  • It seems that “rich” desktop notifications (i.e. which contain clickable links or formatted text) are not recommended:

TODO Hamza:

  • don’t mark messages as read in

  • Remove HTML tags from notification body before sending the message

  • Merge channels into master

  • release to noi



  • Add an automatic refresh of the main window when the browser window receives focus?

  • We can now completely remove the [autorefresh] functionality.
