electricant··on Ask HN: What are you using your Raspberry Pi for?
It mostly is a cool way to waste some time. But why not? You'll have millisecond-accurate timing throughout your network
electricant··on Ask HN: What are you using your Raspberry Pi for?
I have a pi 3 B+ running as an LTE to WiFi gateway. I'm not using the native WiFi but the ethernet is connected to an openwrt router.

Since I had ram to spare it also does:

- dhcp

- caching DNS + filtering

- Mqtt server

- GPS-based NTP server

- Openvpn server to my nas (at a different location) and vps

electricant··on The car is not the future: On the myth of motorized freedom
Author here. Having read the comments let me clarify that I'm not advocating for a world devoid of cars. I'd like that cars could be an option not a must. I totally see that cars are here to stay especially where really needed. But who decides when they are really needed? The owner of course! However, I think that we could perhaps shape our lives for walking/cycling and incentivize public transport whenever possible.
electricant··on Ask HN: Suggestions for a document with passwords etc. in case sth happens to me
Consider storing all your passwords in a password manager. I can recommend pass synchronized with git on PC and smartphone but many other services are available. Then, write your master password (or encryption key password) somewhere your family knows where to find in case of need. This way you do not have to store the full password database in plaintext but only the main password. If you add/delete a password you do not have to print anything again.
electricant··on Ask HN: What crypto payments options should I offer for my VPN?
Mullvad accepts cash payments where you send the amount due via mail. They also offer a choice of Cryptos. See: https://mullvad.net/en/pricing
electricant··on Ask HN: What are some Linux tools to diagnose a system which keeps hanging?
Happened to me on what, if I recall correctly, was a thinkpad t61. In the end it was due to outdated BIOS. Updating it stopped the PC from hanging up.

Perhaps check that your BIOS is the latest version first.

And by the way run also a scan of the RAM with memtest.

electricant··on Popular Linux orgs Freedesktop and Alpine Linux are scrambling for new webhost
Not only alpine linux but also X.Org and freedesktop.org
electricant··on Can you read this cursive handwriting? The National Archives wants your help
Let me disagree. IMHO cursive is faster than print once you get the hang of it.

However my point is valid for print too I guess.

Regarding time saved and the fact that they are two different systems, I don't get it. Time saved for what? They are not so different, cursive is built on top of print, just optimized for not lifting the pen from the paper too often (hence it is supposedly faster to write).

electricant··on Can you read this cursive handwriting? The National Archives wants your help
Today I learned that in the us children are not taught cursive handwriting. This is rather absurd to me. How are they supposed to write?
electricant··on Ask HN: How do you backup your Android?
Syncthing to my home NAS. Bakup is triggered automatically when the phone is connected to the wifi and charging (which happens every night).
electricant··on What is the history of the use of "foo" and "bar" in source code examples? (2012)
The reference to the Monty Python spam sketch is gold :D
electricant··on Why and how we’re migrating many of our servers from Linux to the BSDs
What 'gotchas' exactly?
electricant··on A Book on Linux
Caught me off guard. Great book BTW, but not for beginners
electricant··on Ask HN: What have you built with ESPHome, ESP8266 or similar hardware
I built a series of iot sensors and actuators for home heating. All based around the same modular firmware and hardware concept [0].

We have 3 of those boards scattered around the house and one sitting outside reporting external temperature, humidity, pressure and air quality. The 3 boards inside measure the same values as well but also control the heating system.

Finally, all the data is sent to a raspberry pi over mqtt for logging. Data is presented over a web interface which also allows to set the desired temperature.

Oh, and also a clock with date and time synchronized over NTP showing the external temperature and humidity. Super useful to get dressed in the morning ;) [1]

electricant··on Rust-Written Linux Scheduler Showing Promising Results for Gaming Performance
Well it's not just about Rust. What we have here is pluggable schedulers leveraging the BPF functionality within the linux kernel. They can be written in watever language you like and they are running in the user space.
electricant··on Getting Started with Fail2Ban on Linux
I mapped the SSH port to 122 on the external network while it stays 22 on the LAN. Then, I limit the number of connectons to port 122 at the firewall, using iptables (https://www.cyberciti.biz/tips/howto-limit-linux-syn-attacks...).

Now the failed logins on ssh is down to 1-2 per day instead of hundreds.

electricant··on Ask HN: Anyone Using Peltier Dehumidifiers?
The issue is quite the opposite. There is no airflow. That's why it is so damp. BTW the house is not mine so modifying it to increase airflow is not an option.
electricant··on Ask HN: I don't want to use G Play or Apple APPS, what should my phone setup be?
Ironically, I bought a refurbished Google pixel last year just because it supported calyxos. Never looked back. Just recently they added support for more devices which is great.

If you don't run anything Google on your device, you'll discover that an oldish (~4 years old) phone is plenty.

Some app recommendations: * mapping: osmand * e-mail: k-9 mail * app stores: f-droid + Aurora store * contacts & calendar sync: davx * camera: open camera * YouTube: newpipe

electricant··on Ask HN: What are you reading these days?
Calvino is one of my favorite writers. Let me recommend also: The castle of crossed destinies (the book that got me into tarots)
electricant··on Ask HN: What are you reading these days?
An introduction on marketing and how to set prices for goods and services.

Also not a book but highly recommended: Maus by art spiegelmann

electricant··on Badger Swarm: New Project Helps Privacy Badger Block Ever More Trackers
Thanks for sharing this. Does it add mor value compared to, for example, u-block origin? Shall I use both u-block and privacy badger or either of those will suffice?
electricant··on Open-Source Washing
Me too :D
electricant··on An open-source, free circuit simulator
You should consider using qucs-s https://ra3xdh.github.io/ a fully open-source fork of qucs still currently maintained and improved.
electricant··on Ask HN: What hardware are you running for your home server?
I built my home server in 2013 and it is still going strong. It is based around an ASRock E350M1 with integrated AMD E350 dual-core processor [0].

It sports 4GB RAM an old 64 GB SSD for the operating system (debian) and three 2 TB HDDs in a btrfs RAID1 array giving ~3TB of usable space which is plenty for my own needs.

It runs the following services:

- DNS server (unbound + custom domain filtering)

- Syncthing

- OpenVPN client & server

- PostgreSQL + lighttpd + PHP for various small websites

- Samba & NFS

- Transmission (for linux distros of course)

electricant··on Ask HN: Alternatives to Reddit
I suggest you take a look at raddle: https://raddle.me/
electricant··on Ask HN: Which book would you pick to re-read for the rest of your life?
Neuromancer by William Gibson
electricant··on Ask HN: Which book would you pick to re-read for the rest of your life?
Came here to say the same. Every time I read it it has a different meaning.
electricant··on Ask HN: Why there's no crowdsourced phone number blocklist?
I was thinking more of a blocklist to be applied using the official android API for blocking numbers (https://source.android.com/devices/tech/connect/block-number...).

That's why searching for a number directly won't work.

electricant··on Ask HN: Why there's no crowdsourced phone number blocklist?
Thanks for the input I'll check it out.

What about the URL blocklists all available for free then? The are indeed very valuable aren't they? Why in your opinion aren't they available behind a paywall?

electricant··on Ask HN: What's Your Personal Motto?
"If you want something well done you'd better do it yourself"

No matter what there's always a tradeoff between having something in life the way you like it with lots of effort or rely on somebody else. But when you rely on other people they'll do stuff the way _they_ like.

It's both a motto that encourages me to try new things and invest time doing them but also to respect other people's work and point of views.
