systemfreund··on Linkalot: A web-based inbox for your links
https://getmemex.com/ might be what you're looking for. I've tried to use it, but it somehow managed to destroy its database 3 or 4 times. After that I gave up and uninstalled the extension again.
systemfreund··on How to run your own mail server (2017)
I'd like to point to another smtp server, which I am using and is much easier to set up than postfix in my opinion, especially for small servers like mine: https://www.opensmtpd.org/

I'm running a personal mailserver (opensmptd, dovecot, dkim, spf, dmarc, spamassassin) for some years now and although I initially had problems with deliverability to google there aren't any (apparent) issues so far.

Also I don't understand why people keep emphasizing google's spam filter being so much better than anything else. For my personal server SpamAssassin has proved itself to be more than sufficient, its spam filtering performance is on par with Gmail's (I have a Gmail account aswell), at least for me.

Of course, Gmails spam filter works better for the billions of accounts they manage, but in order to handle the spam of a tiny mail server I'm probably not the only person who is satisfied with SpamAssassin.

systemfreund··on Password expiration is dead, long live passwords
The login form usually sends the password in cleartext and it's then hashed on the server-side prior to comparing it to the hash stored in the database.

So they can just determine the password's strength at the time when the user is logging in

systemfreund··on The discrete-time physics hiding inside our continuous-time world
> The Planck time is by many physicists considered to be the shortest possible measurable time interval; however, this is still a matter of debate. [0]

So, if this is true, then does it mean that time does not 'flow', but rather 'chunks'?

systemfreund··on Saudi Thirst for Water Is Creating a Toxic Brine Problem
Apparently it's for prevention of fouling:

> Combined low concentrations of copper (5 μg/l and chlorine (50,μg/l have been effective in preventing both micro and macro-fouling in over 120 seawater installations since 1987.

systemfreund··on SpamAssassin is back
Not the OP, but I have a similar setup, however instead of Postfix I am using OpenSMTPd, which I found much easier to configure.

Checking for false positives is a manual process. I've never had legitimate mail marked as spam though, only the other way round.

My experience with Gmail's filter is not as nice btw. At work, I had a couple of situations where important mails from a customer were flagged as Spam, which went unnoticed for two weeks.

systemfreund··on GitLab acquires Gitter, will open-source the code
When it's going to be open sourced then we could finally implement a proper matrix.org bridge. Currently all messages are relayed through a special gitter user called matrixbot
systemfreund··on Buttery Smooth Emacs
Could you share details, please? Does it work out-of-the box or what do I need do do this?

Edit: Found it out myself. Install docker-tramp.el [1], `C-x C-f` to `/user@myserver|docker:mycontainer:/`

systemfreund··on Google AI invents its own cryptographic algorithm
It's not clear from the article whether they train the networks with the same shared-key in every iteration, or if they randomize it. Any info on that?
systemfreund··on Ask HN: Is it possible to run your own mail server for personal use?
i consider viber legacy technology because of its reliance on a centralized system and which will stop working as soon as vc money runs out

qutebrowser is also worth mentioning:

systemfreund··on How a comment on Hacker News led to 4½ new Unicode characters
From the Unicode 9.0.0 announcement [0]:

> Important symbol additions include:

> 19 symbols for the new 4K TV standard

I am wondering, why did they add symbols for a standard which will become obsolete eventually?

systemfreund··on Aldi's Barcode Strategy
I dont think this is true. In Germany there never has been a 'bagger-culture' :)
systemfreund··on Ask HN: How do you familiarize yourself with a new codebase?
The font is PragmataPro, which I am also using. Best font ever, but expensive.
