QNAP and expired Let's Encrypt root certificates

We recently received an email into the blisshq.com support inbox…

I’ve been using Bliss on my QNAP TS-219P II for years (currently running

I just uninstalled Bliss (2022 version but can’t remember exactly) and attempted to install the latest 2023 version but for whatever reason I am unable to complete the install (it fails at 4%-5%). Reinstalling older versions of the app (that I found on my computer) also fail even though I had them all installed at one point.

Trying the install myself, on our test TS-251 NAS, I got the same behaviour.

bliss couldn't be installed

This bamboozled me a little bit just now and surprisingly I couldn't find anything online, so I wrote this up. Given:

object MyObject {
    val Log = Logger.getLogger(getClass);

What's the fully qualified classname that you should use in a Log4J configuration?

The recent deprecation of the use of SHA1 derived digital certificates for Windows 7 and later has meant that software developers need to begin signing their software using one of the SHA2 algorithms (e.g. SHA256).

The trouble is that older versions of Windows don't support SHA2. The workaround is to dual sign, but it's not immediately clear how to do this with osslsigncode. Here's how I worked it out!

A first attempt at an OpenBEM 3 assessment

This evening I've spent a surprisingly enjoyable time inputting all my house measurements, U values etc into OpenBEM v3. OpenBEM is an open source building energy model based on SAP 2012. It is implemented and hosted over at emoncms.org.
