Hey bikers in #CambridgeMA: back in December, the city council passed a policy order asking for a plan to redesign Garden St to make it a two-way street again (due to opposition to its current configuration, which is one-way towards #HarvardSq with a semi-protected bike lane on each side). I think returning this street to two-way traffic would be a big mistake! There's a petition to make this clear. It could use more signatures before the report from the Traffic Dept is discussed at the city council meeting next Monday, 3/31. If you're a Cambridge resident, please consider reading more details and signing the petition here:
Please boost for reach (CC @itamarst @Cambikelanes )
(Personally, every time I drive, bike, or walk down Garden St, I'm grateful for how much the current design has calmed down traffic and reduced dangerous interactions, even when the flex posts have been removed.)

This is Apis dorsata the giant honeybee. (People do get honey from them, but it's ... lets say it's nontrivial) I think they might be on their annual migration? This is a bivouac... something normally more associated with army ants.
The bees cluster like this as a show of force, like an army marching in review or a big protest. The message is "we're all together, coordinated and we'll mess you up if you mess with us."
They also cluster like this on their comb.

Trying #FreeCAD 1.0: it can open my keyboard project that I've designed in the realthunder/Link fork! With broken references and —at first— some weird broken origins, but they're fine after unhiding them and resaving the file (what was that even?)
upd: wow a looooot of references are screwed actually
After porting over the keyboard case project… I can say there's still a looot of improvements still missing in mainline #FreeCAD compared to Link. At least:
- Automated creation/management of ShapeBinders;
- Sketcher actually showing current sketch elements always on top, lol;
- intersection as a PartDesign operation (without going through a separate solid);
- actually usable clipping plane view (section hatch, manipulator widget).

I second the idea of a bad contact between probes and sphere.
Ideally spoon shaped probes must give a better contact.

Yeah, I reckon you're probably measuring the resistance of the infinitismal contact patch between the hard convex probe and the hard convex bearing. Grinding flats would be one option, another one might be to crush soft copper foil or wire onto each side and measure the resistance between those.

in reply to smellsofbikes • • •Hi,
lot of interesting answers here. I think there is a contact problem between the bearing and the el-cheapo probes. Even with a cheap meter you should have a decent set of probes. The bearing is very hard and the probes are too soft to bite in and make good contact. If you rough up the bearing by sanding it. It will bite into the probe and make good(better) contact.
flat probe tips would be better.
I would just make some nice soft flat copper contacts and move on.

Starts to feel like a semiconductor somewhere.
I wonder whether grinding a flat in a bearing would create a diode of some sort. Might depend on what metal is use for the probe?
I know nothing about this though. Just wild speculation!

a perfect sphere will only be able to contact a convex body at a single infinitely small point (this is the real world so it wont actually but y'know)
