Visible inside my Costco. Impressive.

Is all this speed (on a phone on any carrier) actually needed? Nope. All I need is a decent connection to send photos of my Costco cart full of snacks and caffeine drinks to my family and friends.

This is a long shot, but does anyone have a portable #cellular signal booster they're willing to part with? The signal strength at most of the state parks I can get to is two to four bars of #4G #LTE, at best.

I've tried to post a video several times now, and it keeps failing.

I wore my Apple Watch Ultra 3 for my 44 minutes of running and a cool down walk. I had GPS on and was streaming live Apple Music Radio via LTE to a pair of Shokz OpenRun Pro 2 headphones.

The resulting battery drop was 7%. Not bad.

Am I on a Vodafone or Three tower?

Since Vodafone and Three have merged together, there's been a lot of confusion on whether you're on a Vodafone or Three tower. Find out now which one you are connected to in a few simple steps.

Cannot describe how much I *hate* eSIM as a technology. We spent decades fighting the cellular companies here in the US, finally dragging them into the civilized world of LTE and physical SIM cards… and now the shitheels have conspired to bring us back to the mother-may-I world of the CDMA 1990s, when you had to call your carrier to beg them to authorize your new phone.

This future fucking sucks.

I hope the Europeans hold the line on requiring physical SIM card slots on phones. Since obviously, expecting anything pro-consumer to come out of the US right now is a ridiculous thought.

Remember when there was #diversity in the #cellular #telephone #smartphone #technology market?

All we get now are Apple iPhones, Google Pixels, and a bunch of Korean and Chinese versions of Android.

So many well-respected consumer electronics companies of the past have fallen by the wayside.

I was thinking about my Braun butane-powered hot styling brush, and wondering why there isn't a Braun Li-ion battery powered replacement for it. And then I thought, why isn't there a Braun cellphone?

@davidgerard if you just need cheap and adequate temporary domestic cellular internet access, I vote for buying a rolling 30d contract, unlimited data sim card, on whichever is the cheapest of the networks that run on the frequencies that your nearest (best line of sight) tower delivers. https://www.cellmapper.net/

🧠🎨 New paper by Meyer et al: #astrocytic #sodium #homeostasis is not uniform. Using multiphoton #FLIM in #mouse #brain slices and #invivo, they show strong #cellular and #subcellular heterogeneity in astrocytic Na⁺ levels.

Processes contain more Na⁺ than somata, Na⁺ varies between #astrocyte branches, and distinct Na⁺/K⁺-ATPase subunit patterns help tune local K⁺ uptake and #glutamate-linked Na⁺ influx.
