And Thanks, Cindy Hess-Luth for saving me the bother of trying to hunt down these statistics!

You should have tried harder. Posting utter guff does you no credit.

A quick look at a sampling of the January and February, 2016, APs that I got early this month, however, seems to indicate that almost all of those were 100% blanked. I'll try to take a more in-depth look at those tomorrow. It looks like the dates on those run from mid-January to early February.

A quick look back here shows that most of the Nov 2015 stuff was OK, but most of the Dec 2015 stuff is blanked.

I've received four more AP tasks from November 2015, and they're all non-compressible.

Blanked... blanked... blanked...

Yeah, at least 90% of 'em.

Compressibility test, anyone?

So just to restate the test, you must catch an AP task that is in queue and has not yet been run, and attempt to zip it. If it's a good AP, it will barely compress, if it's a "stuck bit" unit, it will compress to about 50%. Is that about correct?

Yup, exactly so. The raw file should be about 8MB: the 'stuck bit' ones zip to just over 4MB.

I managed to download Task 5168328866, ap_18no15aa_B3_P1_00346_20160920_22804.wu_1, which is part of workunit 2270430643. It zipped down to 4,808 KB from 8,196 KB. But this workunit is from the infamous "B3_P1" data channel, which generates almost exclusively "bad" data - so no real help there, I suspect.

I snagged another one: Task 5168561759, ap_20no15aa_B0_P1_00090_20160920_32079.wu_1, which is part of workunit 2270541308. It zipped down to 7,975 KB, so it looks okay. Both of these workunits were recorded in November 2015, and I recall that it's the more recent data recorded in 2016 that is suspected to be "dud". I'll keep trying...

Server status page. There's a link to it on the home page of SETI@home, under "ABOUT".

Not so. There's a commercial operation in Singapore.

Wikipedia's page on vertical farming is instructive. However, not everyone agrees that the concept can work.

Food for thought? ;)

I really wish that some of you would have a bit more respect.

Respect?

For this guy?

Frankly, he makes Hillary Clinton look like Mary Poppins.

Respect is earned. In my view, he's not even close. As I've said before, he's dangerous, not only for the USA.

Post:
I was six years old. The moon landing of 1969 is one of my earliest memories.

In South Africa, one of the consequences of the Nationalist apartheid government that ruled the country at the time was that we had no television - it would only arrive seven years later. I recall listening to a live broadcast of the moon landing, and the subsequent moon walk, on a transistor radio in the kitchen of my house in Cape Town. The radio was perched atop a large Amana fridge-freezer combination. Amana is a well-known American brand, so I guess that was appropriate!

I'm going to try to stay up past my bedtime and watch Melania.

BBC - US election: Melania Trump 'plagiarised' Michelle Obama
WP - Melania Trump’s speech appears to have cribbed from Michelle Obama’s in 2008

Imitation is the sincerest form of flattery.

It's akin to shooting yourself in the foot while it's firmly lodged in your mouth. As one wag said on Twitter, I'd rather be the guy who led the failed Turkish coup than the guy who wrote the #MelaniaTrump speech.

I'm sorry, but I simply couldn't get past the idea that ANYBODY on the planet would find an Almond Joy to be "non-essential".

I'm allergic to almonds (among a few other things), so ... non-essential it definitely is! ;)

(Not that they're available in my neck of the woods, anyway...)

at that rate, you are going to run out of size and colour before you run out of tasks :D

you check once a day? care to make a graph? I'd like to make a quick extrapolation.

A linear extrapolation of the data since the beginning of April suggests 26 April at 10:52 (UTC).

Reality - which is represented by the data I have for the deprecation (if that's the right term?) of AP v505, MB Enhanced v6 and AP v6 - dictates otherwise. AP v505 took over a month to process the last 62 tasks; MB Enhanced v6 required three months to process the last 452 tasks, and AP v6 took three weeks to decrease from 452 to 88 tasks, after which the data were no longer available.
