I destroyed an old hdd with the dd command.
The hdd was in a dell laptop from 2005, it had ubuntu 2008 and the game gridwars2 installed. I wanted to backup the disk as soon as possible because gridwars2 works only in ubuntu 2008, so I ran dd and piped through ssh.
The disk stopped working after reading 9GB and started to make a strange noise, I was not in front of the computer it happened, when I saw this happening the disk and laptop were very hot (more than 50 degrees). I turned off the computer and now when it doesn't boot anymore and the disk makes a strange noise and it turns itself off after 5 seconds.
I updated a let's encrypt certificate and I have got connections the following IPs:

I'm adding gemini support to my browser `bato`. I'm browsing gemini space to test it.
We slept outside in the forest last saturday. It was 14 degrees(C) and cloudy and since it was the longuest day of the year, it was not dark. I slept with the sleeping bag on my head to block the light. 6-7 crows came at 4am to eat the dinner leftover until 6am, they were fighting and making noise.
I rented a DS 7 (citroen) rechargable hybrid car from hertz.
When I drive normally (in hybrid mode) it doesnโt charge the battery so it runs on gas (in flat areas). The electric motor is used only at low speed in parkings.
I charged the battery on rรฉ island (France) with a 36kw charger on a parking. According to the dashboard, the car can drive 26km per hour of charging, it is too slow. On rรฉ island, most chargers are 36kw (more than 20) and there is one 48kw charger, it must be tough for electric cars.
Payment
I tried to select and pay with the touchscreen on the charger but it didnโt take my credit card (maybe because it is a foreign credit card). So I scanned the QR code on the charging station, it opened a web page and I entered my email and my credit card number and pressed start charging.
The charging station only need the credit card number, taking email is just collecting information for other purposes.
The service is called electromaps and the charging station is called MObiVE.
There was no way to check if the QR code was correct, anynody can stick a QR code on the charging station.
There are 3 types of plugs (CHAdeMO, CCS2 and Mennekes) and the plugs have different power. The CCS2 plugs have the most power in general.
The DS 7 has a mennekes plug.
I couldnโt stop charging with the touchscreen on the charging station, I had to reopen the web page and reenter my email to get a stop charging button on the page.
This car can drive 50km in electric drive mode so it is for commuting only.
I'm using SSH over mobile internet. With 4G, it is very slow and it drops many packets. With 5G, it is fine and responsive.
Lagrange works and elaho doesnโt seem to work. Ssh also works but it is slow with more 1 second latency
Gemini works fine an airplanes. Im somewhere above Germany
Terminal demos:
I rented an electric car (Skoda enyac iV 80) last week in Corsica (France) from Hertz. Hertz didn't tell in advance if the car was ICE (gas) or EV.
I thought the battery performance would be bad while driving in mountains but it was not possible to change because Hertz only rents EV in Corsica.
I had to install an app (e-motum) and create an account to be able to see the location of the charging stations.
I only used 150kw charging stations while shopping for food. Charging 20mn added 25% to the battery level. I paid on the charger with my credit card, same as gas station, no need for an app.
Driving from Bastia (sea level) to Crocicchia (700m) about 30km took 8% batery and driving back charged the battery by about 2%.
I think I could drive between 250km and 350km with one charge. When the car is charged, it shows 550km range, it is optimistic.
This CVE in less is intriging:
https://www.cve.org/CVERecord?id=CVE-2024-32487
When the environment variable LESSOPEN is set and less opens a filename with a newline '\n', it will execute the text after the newline as a shell command.
This is because less uses the shell (with popen) for globbing and didn't escape newline characters.
This security issue is fixed in commit 007521ac3c95bc76e3d59c6dbfe75d06c8075c33 (2024-04-11).
https://github.com/gwsw/less/commit/007521ac3c95bc76e3d59c6dbfe75d06c8075c33
It was introduced in commit 5a9639f09c138cb489ef5d8f8b20fc28b542e37f (2002-01-14).
My IBM Thinkpad laptop from 2003 stopped working 2 days ago. I changed the power supply and it was still not working. Finally, I removed the battery and now it works again! Before the battery died, the laptop could run 5 minutes without power supply enough to move it around plug it again.

Yesterday, I tried accessing one of web server from my mobile phone and it didn't work.
I use http://freedns.afraid.org/ for the DNS, I checked it and it was ok (I have to log on freedns regularly every third month to keep it working).
I connected to the web server from a computer and I was ok (2 days ago wifi was down for the computer).
At this point, the issue is either the mobile network or the modile phone.
I switched to plane mode and then disabled it to reset the modem in the phone.
After that, I could access my web server from my phone again.
It is the first time this happens in 3 years.
I tried Serenity OS today.
After compiling in Debian Bookworm, I get the error:

Then I get another error:

And it doesn't start.
Honey shrinkflation
Some small C compiler information:
- cproc doesn't have a preprocessor
- chibicc takes only c files as parameters
- tcc (tinycc) can compile libsheepy programs (C11) but they crash on execution and debug symbols (dwarf and stabs) are incorrectly generated so they can't be debug in GDB
It would be good if tcc could compile sheepy programs because it compiles 10 times faster than gcc.
Rob Pike's 5 Rules of Programming
- Rule 1. You can't tell where a program is going to spend its time. Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you've proven that's where the bottleneck is.
- Rule 2. Measure. Don't tune for speed until you've measured, and even then don't unless one part of the code overwhelms the rest.
- Rule 3. Fancy algorithms are slow when n is small, and n is usually small. Fancy algorithms have big constants. Until you know that n is frequently going to be big, don't get fancy. (Even if n does get big, use Rule 2 first.)
- Rule 4. Fancy algorithms are buggier than simple ones, and they're much harder to implement. Use simple algorithms as well as simple data structures.
- Rule 5. Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.
Pike's rules 1 and 2 restate Tony Hoare's famous maxim "Premature optimization is the root of all evil." Ken Thompson rephrased Pike's rules 3 and 4 as "When in doubt, use brute force.". Rules 3 and 4 are instances of the design philosophy KISS. Rule 5 was previously stated by Fred Brooks in The Mythical Man-Month. Rule 5 is often shortened to "write stupid code that uses smart objects".

My iphone battery lasts 2 days and before iOS 16 it was last 4 days, so I started change settings to save power.
The system (software updates, Apple ID,...) uses most of the data, since yesterday my iPhone transfered 34.9MB (using it less than 5mn), the system transfered 26.1MB and my apps the rest of it.
- Setting power save mode doesn't change how long the battery lasts
- Turning off mobile internet and wifi doesn't change how long the battery lasts
- Turning off GPS doesn't change how long the battery lasts
The SoC is idle and only bluetooth is on. Maybe the battery loses power just by itself, according to the phone the battery is at 85% original capacity.

Someone connected to my radio station (see below).
I'm not alone :)
Real world onion sites
https://github.com/alecmuffett/real-world-onion-sites
Here is the radio program, it is a chat system using UDP on port 1886 to transmit the message.
The messages are encrypted, each time radio is turned on, new secret/public key pairs are generated and exchanged with the server (radio station).
If you are behind NAT, you should forward port 1886 to the machine running radio, without this you won't get any signal from the radio station.
The UI is in the terminal and works with the mouse like a GUI.

http://gmi.noulin.net/radio.gz
To start radio, run:
wget http://gmi.noulin.net/radio.gz gunzip radio.gz chmod 755 radio ./radio
Screenshots:

The source code is available at:

It is written in C, it depends on:
my sheepy build system and library
The main file is `radio.c`, `radioStation.c` is the server and `radioSignal.*` implements the protocol.
The `twid` (terminal widgets) is the TUI built on my version of termbox.

Implement strlcpy and strlcat [BZ #178]
These functions are about to be added to POSIX, under Austin Group
issue 986.
The fortified strlcat implementation does not raise SIGABRT if the
destination buffer does not contain a null terminator, it just
inherits the non-failing regular strlcat behavior.
