While preparing a scan of ladder manual I ran into a strange issue with a PDF produced by my Xerox® WorkCentre® 3225 MFP. Firefox was rendering the first page of the document normally but contents of the rest of the pages was shrunk in one direction.

Recently I couldn't find manual for a ladder I bought in Lidl. Despite the fact that Lidl has all their non-food products marked with IAN I regularly run into certain numbers not being known to their search on customer-service.lidl.ie.

This time I couldn't find online manual at all. So I got a paper version and scanned it (English part only, sorry I was a bit too lazy to also scan the German part).

Parkside multifunctional ladder IAN 452018_2310 manual

This manual is very similar to that of Parkside multi-purpose ladder IAN 478540_2410:

• English and German
• Multiple languages

Recently I was setting up a Linux laptop where I mostly have no root access. I prefer i3 but since the distro I have to work with is shifting towards Wayland I decided to give Sway a try.

One aspect that required explicit configuration was ssh-agent.

From time to time, when I upgrade my standalone Unifi controller (running in FreeBSD jail), I run into an issue which requires some manual action to resolve. The issue manifests as MongoDB (bundled with Unifi controller) refusing to start with existing data. Checking logs (/usr/local/share/java/unifi/logs/mongod.log) I can see the following (this log file is in JSON format - not particularly friendly for humans but still readable):

{"t":{"$date":"2025-02-01T21:39:17.097+00:00"},"s":"F",  "c":"CONTROL",  "id":20573,   "ctx":"initandlisten","msg":"Wrong mongod version","attr":{"error":"UPGRADE PROBLEM: Found an invalid featureCompatibilityVersion document (ERROR: Location4926900: Invalid featureCompatibilityVersion document in admin.system.version: { _id: \"featureCompatibilityVersion\", version: \"4.4\" }.

I'm not very experienced with MongoDB and this message looks rather obscure and scary. Fortunately so far it was fairly easy to fix.

Writing this mostly as a reference for myself should I run into this problem in the future.

Pasting into vim running under tmux was producing weird results. For example pasting wiwiw would actually produce Wiw.

I had a chance to try Zigbee extension lead sold by Lidl under SilverCrest brand.

Browsing the list of ESPHome components I noticed a picture that looked very familiar. In my house I have this device branded as "Joule" and labeled "DeltaSolⓇ BS HE" and on ESPHome site they show "Resol DeltaSolⓇ BS Plus":
