So....after this weeks #BitFlip episode (https://bitflip.show/6/) I put my money where my mouth was and picked up a Snapmaker U1. Shipping was quick (ordered Thursday, arrived Saturday). Setup took a bit longer than I remember setting up my Bambu P1S, but so far I am impressed.

Initial impressions from first print/setup:

- Print quality seems good
- Touch screen is nice
- It's biiig.
- Absolutely floored by the Klipper/local control. It has a webui!!!!! HomeAssistant data is incredibly detailed (to the point of likely overkill)

Still to do: Install the Paxx12 extended firmware (because of course I am) and get the setup/integration between Spoolman and Snapmaker working with some NFC tags.

I don't know what I"m going to do with my P1S at this point, but I think I've just entered heaven when it comes to open source prints.

How Alpha Particles Can Break Computer Chips

#Computers are wonderful... they still surprise me once in a while.

One of my #tasmota devices just stopped answering commands via #mqtt but was happily reporting status back via MQTT.

After a lot of debugging I found that the MQTT topic changed from /cmnd/... to /cmjd/...

j in ASCII is 0x6E or 0b010 1110
n in ASCII is 0x6A or 0b0110 1010

So basically one bit flipped from 0 to 1.

Bit flip? Table flip!
(╯° °）╯︵ ┻━┻

That is my first self-observed obvious bitflip. Hooray!

So I will now configure the MQTT Sender to use cmjd for this device, obviously...

What will you bitflip today?

I want to let you into a secret: I enjoy corruption. Corrupting digital objects leads to undefined behavior (C++’s definition is fun). And flipping bits in objects can tell us something both about the fragility, and robustness of our digital files and the applications that work with them.

I had a pull-request for bitflip accepted the other day. Bitflip is by Antoine Grondin and is a simple utility for flipping bits in digital files. I wrote in my COPTR entry for it that it reminds me of shotGun by Manfred Thaller. The utility is exceptionally easy to use (and of course update and maintain written in Golang) and has some nice features for flipping individual bits or a uniform percentage of bits across a digital file.

My pull-request was a simple one updating Goreleaser and its GitHub workflow to provide binaries for Windows and FreeBSD. I only needed to use Windows for a short amount of time thankfully, but it’s an environment I believe is prevalent for a lot of digital preservationists in corporate IT environments.

Bitflip is a useful utility to improve your testing of digital preservation systems, or simply for outreach, but let’s have a quick look at it in action.

Anekdotisch, aber interessant:

»Ich habe eine Samsung EVO 860 mal "zufällig" nach einem Jahr wieder an den Rechner angeschlossen:
Der Start von Windows 7 hat geschlagene 8 min gedauert und der Zugriff selber lief auch ziemlich langsam, während ich im Hintergrund viel Schreibaktivität vernahm... Meine Vermutung: die Platte hat sich einmal refresht und musste somit alle Zellen einmal anfassen…
Ein #Bitflip ist also bei einer #SSD wahrscheinlicher als bei einer HDD.«

bon ou est ce que je peux trouver de quoi confiner des disques durs afin qu'ils résistent à des impulsions électromagnétiques.
parce que hein, y'en a qui ont regardé Blade Runner, et y'a les autres.
