Saw some silicon valley types freaking out about the "slow uptake of AI" but it's not at all surprising considering the mechanisation, computerisation and network...isation(?) revolutions are not at all complete.  Manual processes everywhere, particularly in the physical world.

Also - why three planets in the background of the SOHO animation?  It's because Mercury, Venus and Mars are all very close to opposite us behind the Sun.

You should automatically dislike online-only installation.

In some cases you want ONE file, ONE version that installs exactly as-is, deterministically.  No updates.

And definitely no "remote server decided you aren't allowed to use software any more".

Last week I looked inside Brookhaven National Laboratory's tandem Van de Graaff accelerator.  The platform in the middle is called the terminal and can be raised to 15 million volts while surrounded by insulating SF6 gas (unusual to see an accelerator large enough to climb inside!) I wanted to see if there was room for an ultra-cold ion source, which could create nanometre-scale ion beams once accelerated by the Tandem.  #physics #accelerators
