#OTD 1962 John Glenn became the 1st American to orbit Earth🌎
The 60-yr-old 16mm flight film has undergone a transformative process (utilising over 1,000 image samples of the film here) for #GeminiAndMercuryRemastered, to bring out never-before-seen detail:

🛰️ Though largely invisible to the naked eye, over 12,000 operational satellites currently circle Earth, delivering countless essential services. Yet with launches accelerating at an unexpected rate, we face the question – how can we ensure a sustainable space future?

How the west fell behind in the green tech race European companies pioneered much of the technology used in renewables, but have they left it too late to compete with China?

I was surprised to wake up to a covering of snow this morning ⛄️ Petts Wood near Orpington (SE London/Kent border)

The number of active satellites in orbit has now passed the 14000 mark according to my estimates:

Amazing how so much was achieved with relatively primitive technology!

Test drove the Geely EX5 last week thanks to Everything Electric YouTube video. Lovely car from the same parent company and more affordable. I think it will do really well. Your blog about hybrid cars was spot on!

Bit of a NW'ward shift in the models overnight, in respect of the very deep depression being signalled by all models now.

I tried it, but I’m sorry to say it’s not good… bit of a downgrade. Too much text and wasted space. For starters, compare wind details between beta and exiting app. Also, cannot even scroll hourly forecast between days… 🤔

The safety systems in modern cars are far better at staying alert than an average human. I use lane keep assist on the motorways all the time, and if you’re stuck in traffic the “follow the car in front” cruise control is so nice. Can’t see a problem with any of it… safer and easier driving.

Funny how experiences can differ… when I first drove an automatic in 1997 (trip to USA) I couldn’t believe how easy and relaxing it was compared to manual transmission. Felt like we were being ripped off over here by being charged more for autos. Got a Merc B class auto in 2006 and never looked back

👍🏼 upgrades which you don’t notice are the best!

Did you notice any difference with “Zara”? I skimmed the new features list and the changes seem mostly cosmetic?

I remember my thermodynamics lecturer getting very excited about heat pumps in 1992: “1 unit of energy in, more than 3 out!”. It has taken too long to embrace this technology due to the usual resistance to change and FUD.

Pretty sure MS are just trolling us now… What with the Win10-11 forced hardware upgrade, Copilot crowbarred in everywhere, broken updates (my laptop told me I had to install “Win11 repair edition” yesterday to fix broken automatic updates - no joke!). Migrating all family off MS by end of the year 🥳

Looks like a decent upgrade with HDMI and Ethernet ports for starters… if it’s priced competitively then it should sell very well! 👍🏼

Issues with MTK 2503D chip (with a built-in MT3333 positioning chip) · Issue #5634 · traccar/traccar Statement on Positioning Issues of GPS Devices Equipped with MTK 2503D Chips.pdf

This page specifically mentions the GPS date bug affects (at least) the MediaTek MTK 2503D chip with a built-in MT3333 GPS. Workarounds are given in the PDF linked in first comment…

There seems to be a date bug which affects some GPS chipsets (started 17th Aug). If your GPS is showing dates around Jan ‘06 then it’s likely the same issue. See QRP Labs forum post here:

Any idea of maximum drive size it will recognise? 2GB? 😬 I’ve got an IDE to Compact Flash adapter which might work with a memory card partitioned to a small size? Let me know if you want it - happy to post it.

I like Raspberry Pi’s for running 24x7 stuff like PiHole, Homebridge, NAS etc. But many bargain small PCs on eBay etc. which are way more powerful than a Pi and cheaper - bought a Lenovo V520s 8GB RAM 500GB SSD i5-7400 for £35 inc delivery - felt a bit guilty! Many for sale as Win11 not supported 🙄

Is a Pi4 powerful enough to run FT8 properly? On a busy band does it not run out of time and so you miss some decodes/stations?
