m4lvinon Lenses

Funny coincidence. Yesterday I watched the talk by SPJ about Lenses and it finally clicked for me :-)

Maybe someone has an actual public link to this with no login needed?

m4lvinon Mutt – Text-based mail client for Unix

mu4e works great in Termux :-)

m4lvinon Open Source Calendly Alternative

What if I do not have a google account?

Why is this better than framadate? https://framadate.org/

m4lvinon SnappyMail – Modern, lightweight and fast web-based email client

Related: RainLoop (of which SnappyMail is a fork) seems to be no longer developed and has a known stored XSS problem: https://blog.sonarsource.com/rainloop-emails-at-risk-due-to-...

SnappyMail is not affected by this and seems to be the successor.

m4lvinon Show HN: I am building a free version of Strava

I wish there would be a self-hosted fediverse version for the community features of strava. Luke Picciau has built PikaTrack, but not edited it in the last two years. Still, maybe this is some useful inspiration if you intend to extend your app in the community features direction:

m4lvinon Ask HN: Why can't I host my own email?

There are sane email providers who do exactly this, for example Posteo — see question "Is there a spam folder" here: https://posteo.de/en

m4lvinon Can you be sure to clear a line at Tetris?

Is there a good way to reduce SAT or other decision problems to Tetris? Do we need to enlarge the grid to reduce larger problem instances, or can the duration of the play / length of the sequence be used for that?

I would hope for something like "This list of clauses is satisfiable iff there is a winning strategy to clear at least N lines when given the following sequence of tetrominoes". (Where the article here says that there is no hope for anything like this with N=1, but )

Or does knowing the whole sequence in advance make any sequence easy to play / clear any number of lines?

m4lvinon Git security vulnerability announced

I assume the patch will be backported and there will be a point release .30.? including it, but bullseye will probably sticks with 2.30.

However, you can use bullseye-backports to get 2.34.1 if you want: See https://packages.debian.org/git

Edit: None of the debian versions have the patch yet: https://security-tracker.debian.org/tracker/CVE-2022-24765

m4lvinon My Mathematics PhD research workflow: LaTeX notes and instant pdf referencing

PDFs can already contain videos and JavaScript. But given the security problems, I consider it a feature of most non-Adobe PDF viewers to not support that.

m4lvinon W3M Rocks

One example: When I open this page here, in eww all comments have the same left margin and I have no idea what is a reply to what, but with emacs-w3m the nesting structure is visible.

m4lvinon New EU law could require iMessage and WhatsApp to work with other platforms

Why? (Note that the idea is to force the big players to allow interop with small ones, but small startups are not forced to do anything.)

m4lvinon Random number generator enhancements for Linux 5.17 and 5.18

I first assumed it was a PDF and when I got to the video thought "Wait, browsers do video-in-pdf now?"

m4lvinon Osm.el – OpenStreetMap Viewer for Emacs

This works great, in particular on the Purism Librem 5 :-)

m4lvinon Ask HN: Alternatives to 1Password

Pass is the best! As an alternative to the git sync you can also sync via nextcloud or syncthing :-)

m4lvinon Tell HN: SWIFT is not a payments transfer system

m4lvinon Littlefs – A little fail-safe filesystem designed for microcontrollers

This is used in InfiniTime, the PineTime smart watch firmware :-)

See https://github.com/InfiniTimeOrg/InfiniTime/pull/438

m4lvinon Gitlab is down

It is updated by now - some seconds delay is fine I think and if they would not cache the status page it might go down in a blink now too ;-)

m4lvinon XMPP: The secure communication protocol that respects privacy

I have my own XMPP server ;-) and I understand the underlying problem here. I mostly wanted to point out that for a new person to quickly try out Movim this might be a stumbling block. As another comment suggested using something like OAuth to smooth this out might help.

m4lvinon XMPP: The secure communication protocol that respects privacy

I wanted to try it out, but this is annoying:

- registration happens on https://api.movim.eu/register and firefox provides me a way to generate a password and save it linked to that domain.

- now I want to log in at https://mov.im/?login but firefox has no idea that it should use my api.movim.eu account for that.

m4lvinon A curated list of warez and piracy links

DMCA in 3, 2, 1, ... ?

m4lvinon Poll: How much time on average do you exercise in a week?

+1 for clips, and +2 for shimano SPD sandals!!!

m4lvinon Ask HN: 27, accidentally became wealthy, lost drive. What should I do?

Get a nice bicycle.

m4lvinon Xsnow

Wonderful.

But why does snow not stick on Electron windows? Are they ghosts!?

m4lvinon Essential security for Linux servers (2013)

I think most consoles that cloud providers offer are attached via virtual serial consoles (ttys) and not via SSH. So you can disable passwords for SSH but still use them via the cloud provider remote console.

At least for KVM based virtual servers that I have this is the case.

m4lvinon Show HN: P2P remote desktop – an alternative to TeamViewer / AnyDesk

For those wanting a simple Linux alternative: If you have SSH access as the same user as the one running the X11 session on the remote host, you can do this:

    ssh -v -L 5900:localhost:5900 user@remotehost 'DISPLAY=":0" xterm -e "x11vnc -localhost"'

And then

    krdc vnc://localhost

or whatever VNC client you like.

For linux-to-linux this has replaced TeamViewer for me, together with zerotier.com for getting through NAT.

m4lvinon Google Chromium, sans integration with Google

vscodium by default only offers extensions from https://open-vsx.org/ But I am not sure whether that repo accepts non-free software.

m4lvinon Dino – A web app, mobile app and desktop app for jotting down thoughts

One of probably many name clashes: https://dino.im/

m4lvinon Ask HN: What browser extensions are a must-have in 2021?

Okay, but how do I get Edsger(!) Dijkstra as a Firefox add-on? ;-)
