In this particular case, the main stream parties did not take part (i.e. field candidates) because the current MP (Farage) resigned just to retake his own seat - basically trying to distract from his dodgy dealings with crypto bros and convicted fraudsters.

I would have voted Count Binface too (as the least absurd candidate).

On Debian, install rsyslogd instead - it's that simple.

And still does. I generally replace journald with rsyslogd on systemd setups.

And kids. I recently happened to see a pic on a kid's phone of him holding 5 vapes and a tin of snus, when challenged on it he said it was an AI-generated fake.

Jaw-dropping stuff, looking forward to pointing 9-year old daughter (in "Future Astrophysicist" t-shirt) at it!

Possibly a naive question, after surfing the image for a while I didn't find any einstein rings (or arcs) - are they just rare/wrong scale or something else?

and thank you!

Shhh...you'll alert the models :)

Totally agree though, anyone with a vague understanding of how bikes works ignores the pelican because they know the bike is unrideable in the first place.

Indeed, decline appears to accelerate significantly in 2023 so seems likely that's AI helping things along.

We only do it for one-off age verification, not stuff that requires repeat authentication (those we simply don't use).

As a purely tactical measure, we use the same older person (me) for age verification for all family members - zero failures so far and it poisons the well.

Absolutely this will work, it's all over social media.

First place to look when this sort of thing happens is pprune.org - lots of pilots on there, often with specific knowledge of the aircraft type and/or of the incident itself.

New comment by zh3 in "The bottleneck might be the air in the room"

zh3 — Sat, 04 Jul 2026 08:38:05 +0000

For the DIYers, it's simple to get an SCD4x sensor and hook it to a pi, arduino, ESP32 etc (then use CC to create a live web interface). I did this after trying an Inkbird CO2 monitor, which gets reasonable scores in reviews and wanting a live web report in the office.

Interestingly the Inkbird and the SCD4X quite often diverge by anything up to hundreds of PPMs; I kind of back the SCD4x (on a Pi in my case) for accuracy after lots of experimentation, reading the datasheet and ensuring the correct calibration procedurs are followed (basically expose the sensors to outside air once a week).

It's also interesting how much it varies day to day in my one-person office - possibly down to how windy it is outside, even with windows closed one day it never goes about 800ppm, other days it'll hit 1500ppm by lunchtime if I don't open a window.

N.B. Quite possible the Inkbird uses an SCD4x internally, seems reasonable kit so I have no explanation for the differences in readings.

I get he's not popular. None the less it would be nice to see more nuanced comments.

In my experience IPO's often follow a short-period of upside (where those who already have shares gain some liquidity, i.e. actual cash) followed by a dip and then - depending on fundamentals - over time rise above the offer price. Mileage may vary.

I came across this one by accident one day:-

* https://www.remotelondon.com/wisley-airfield-an-abandoned-ru...

Doing a long bike ride to visit a friend, the route I'd plotted suddenly found me in the middle of a big old runway, weird to see given it's alongside one of the major routes into London (one I've driven or motorbiked many times, but never cycled). Quite the shock to see, especially as it was a scramble to get through the bushes and cross the A3 to Wisley RHS.

Yes, when it makes the front page of the FT (2 days ago) you know there's some interesting stuff going on. The whole article is worth a read (I didn't known JD Vance's career was "largely bankrolled by Thiel").
