@meaning_matters @cqcqcqdx That’s an SLC I think - you could pull the board out at the back on an ELC? Wrote my thesis on an SLC.

@cqcqcqdx On the side what seems to be a SPARCstation ELC, first computer I had at my desk. Loved it.

@ElectronicsbyJH @tinytapeout What’s your view of the RFSoC board, seems like a relative bargain?

get into debt if you must, but buy an FPGA board and get into ASIC design (@tinytapeout)

@ElectronicsbyJH Close the browser tab, and step away from the keyboard!

One can only dream...

@ElectronicsbyJH Eeeek! Yeah, well the CC output impedance is low, like really low.

Anyone spot the issue(s)?

@ATaylorFPGA Nice! A bit of a reverso too - test gear being a couple of orders of magnitude cheaper than the device under test :)

It has been a RFSoC kind of weekend.

@GigglyPigeon Agreed. Nephew was close to stepping out in the previous bout. Yoko show down on day 5? Who drew short straw I wonder…

@GigglyPigeon No sure if Papayasu had read the script…

@mouthofmorrison Lol! Must have banged my head as a child.

@robert_watson Who hurt you

I follow 2,200 people and you aren’t one of them? Why?

@adrianbowyer Sample size too small, needs more data.

@drp297 No.

@drp297 We are checking...

Has there been even a single overtake? #monacogp #BBCF1

@Identatron @ECSUoS I’m terrified by that Win ‘95 book. That must be a crime in itself 😬

Outreach Day! Today I'm (hopefully) entertaining 70 teenagers (14/15) with a brand new #dfir case. It was a late night finishing everything but I'm excited by what we've produced especially our signature character videos. The only question is .... Where's Babbage ? @ECSUoS

@TheRealMike Zones are still useful to illustrate climatic differences. No Longley-Rice. Guess I’m just disappointed that for a 2024 release the content is quite so old - analogue video and SSB voice - no DVB, no OFDM etc.

@robert_watson The rain zones were quite useful. Your non-relative at the time, Peter, was involved in a study to see if the rain zones had changed with climate. Ippolito was the go to reference in the late 80s. Surprised Longley-Rice isn't there, or is it?

Thought I'd check out the 5th edition of Roddy et al., Sat Comms book since it was available online at the library. Opened the chapter on Radio Wave Propagation. Quickly closed it.

@TheRealMike A bit of a blunder. I was optimistic it would be updated but it’s still all Crane, Ippolito, ITU-R rain zones and CCIR references. Not that any are bad just quite dated.

@robert_watson Oh dear

@CorwinWright But boy those Cb thunderstorm clouds are high.

@CorwinWright Ahh, makes sense. I was wondering where you got three times better than STRM data for free. (Environment Agency has limited area lidar data for £££)

@CorwinWright Where do you get the 10m resolution DEM data from?

@Gammitin SunOS 5.7 , IRIX 6.4 and NT4.

Let's go back in time, 25 years ago to 1999; what was your daily driver Operating System?
