Also related: any good peertube instances I can start putting video stuff up on?

I'll probably keep uploading things to YT as well at least for the near term but I'm looking at alternatives.

Beginning to wonder about moving to a new instance in the indefinite vaguely near future, since IOCX admins seem to be a bit behind the curve (we're still on mastodon 4.3.7).

I poked them but havent heard back or even seen any posts from them in a while, which makes me wonder if I'm living on a ghost ship.

Anyone have suggestions on one that's generally friendly to cool EE research, OSS/OSH, infosec, etc stuff?

Hey @seb @seb @elefant just wanted to check in on how things are going w/ IOCX? It looks like we're still on Mastodon 4.3.7 which is a bit out of date and I haven't seen admin updates in a while.

Is there a problem? Should I start looking for a new instance?

Finance people: If I have a list of mutual fund symbol names and percentages of each, is there an easy API or data source I can use to calculate what my actual underlying equity exposure is?

The specific goal is figuring out how much of my 401k is actually in companies that are propped up by the AI bubble.

I can look at a single ticker symbol and see at least its top n hodlings easily enough but what if I want to know across ten different index funds I own different amounts of, how much of that is tied up in nvidia?

What's your record for the most levels of nested/chained remoting/virtualization?

I think my current record is:
* RDP from Linux endpoint to locally hosted Windows VM
* Proprietary remoting protocol with Windows-only client connecting to Windows VM on customer infrastructure
* SSH from that VM to Linux bare metal box in customer lab
* SSH from *that* box to actual DUT

There might have been one more hop of SSH somewhere in the chain I can't remember now it was a ways back

Hmmm.

I wonder how hard it would be to implement a 10/100baseT PHY on Trion.

I've already done it with a Spartan-6 and a dozen resistors (TRAGICLASER). Trion doesn't have IOSERDES so I think I'd need to use regular ddr flops in a 2x clock domain but simple logic at 250 MHz in a Trion should be doable...

My daughter just yelled "shark attack" and threw a blahaj at me.

Clearly we've trained her well

Randomly reminded of the story my mom told me about when she worked at a Dunkin Donuts in college.

Apparently the locals would always ask for "barbarian cream" donuts.

Also I forgot how big the die was, I thought I had left enough of an aperture but didn't quite etch the southeast corner enough. It's not covering anything I care about though.

Next step in the PIC12F683 project, a partial decap.

Tried some new techniques that worked great, but let a bit of acid on the back that caused minor corrosion on the die attach paddle. I know how to prevent it next time though.
