Whoops, almost forgot - the Genus Callicore also contains numerous "eighty eights". Callicore pitheas is a typical example.

My regret is that the article didn't identify the species concerned ... otherwise, I would have had lots of fun tracking them down!

The problem is that there's an entire Genus of butterflies, namely Diaethria, whose members have "80" or "88" wing patterns, of which Diaethria anna is but one of about a dozen such species ... Diaethria anna can be viewed here.

If you go to this huge list of butterflies found in the Americas, you can search through the Genus Diaethria and see a huge number of photos of the butterflies in question. For example, this page covers Diaethria astala.

I think it is gorgeous! Did you let it stay or escort it outside?

All my specimens are released into the wild, unless I'm informed beforehand that the specimen is of interest to scientists.

My son-in-law (in UK) can only tolerate spiders in the house if he gives them a name  :). Here in Oz we have a constant supply of house spiders but none as colourful as yours.

Actually, if you check out the various Peacock Spiders that live in Australia , you'll find they're very colourful indeed! This scientific paper covers spiders of the Genus Maratus, which contains the Peacock Spiders, and I think you'll agree they're well worth looking out for!

Meanwhile, a pretty thorough run-down of the various Australian members of the Salticidae can be viewed here, but be warned you have a LOT of photos to scroll through on that page. :)

For example, Simaethula auratus looks as if it's made of opal.

In the Araneidae, Eriophora curculissparsus is mint green, and Araneus praesignis has a mint green cephalothorax with a white abdomen. You also have several interesting black and yellow striped Argiope species to look out for in the same Family, along with odd looking species in the Genus Arkys. Also check out the Genus Austracanthus, which contains colourful and bizarrely shaped six spined spiders, as does the related Genus Gasteracanthus. In particular, Gasteracanthus westringi will probably leave you with your eyes on stalks when you see it! These and more can be viewed here.

Also see the Australian members of the Family Thomisidae,

Several of the smaller Huntsman Spiders belonging to the Genus Neosparassus are bright green. The big, scary ones belong to the Genus Heteropoda - but as big as the Australian members of this Genus are, they're eclipsed by Heteropoda maxima from Laos, which has, wait for it, a 12 inch leg span. That is NOT a species that should be searched for via a Google search by arachnophobes!

This little beastie turned up in my home on 2021/05/20.

Don't worry, it's only small, it just looks huge in the photo because my camera has a super macro zoom facility that can make a small coin look like a manhole cover. :)

What struck me about this was the fact that while I was photographing it, it appeared to have an iridescent metallic green abdomen - not the sort of colour scheme usually associated with British spiders!

Specimen has since been identified as Philodromus aureolus.

To give an indication of actual size, the leg span is only marginally wider than the diameter of a UK 5p coin (which is a pretty small coin).

In the past, I've had the related Philodromus dispar turn up in my home, whose adult males look as if they're wearing a tuxedo colour scheme wise.

Not a biggie, but the state I live in is spelt Illinois and the expression 'there is no noise in Illinois' is for those pronouncing the final letter (it is silent).

Tangential diversion moment ... you just reminded me of this album by Sufjan Stevens :)

What's the hex code for that shade of red? Might use it myself in a future JavaScript project! :)

And, of course, Alan only has finite time to devote to updating the database. And relies upon us to let him know of such anomalies. :)

Anyone who learned about software development on a UNIX system and spent time playing Colossal Cave will know about this. :)

Speaking of "who picks these words" ... today's Standard (5th April 2021) strikes me as being some sort of late April Fool's joke.

I can't see any way of making just ONE nine-letter word out of that collection of letters, let alone two ...

EDIT: just 10 seconds after posting this, I found the two nine-letter words.

Even so, this puzzle is probably one of the most exasperating I've played to date.

I've always seen these logic gate names written in all capitals, as you've done, whisky and ridethetalk. That would rule them out as Chi words.

Also, isn't exclusive or normally written as XOR? At three letters, this is too short for us.

These are also basic machine language operations for CPUs. However, depending upon which CPU you're referring to, different conventions apply to the exclusive OR instruction when these are written in assembly language.

For example, in the case of Intel or Zilog processors  the operation is described using XOR. So, for example, on a Z80 CPU, you can have and instruction such as


which performs an exclusive OR operation on the contents of the accumulator with itself, or


which will perform an exclusive OR operation between the contents of the accumulator (A) with the B register, the result being stored back in the accumulator. There are also variations on the XOR instruction allowing the use of memory based operands, either using an absolute memory address, or using the HL register pair as a pointer to the memory operand, as in:


Likewise, on 80x86 processors, you can have instructions such as


and in the case of processors from the 486 upwards, the operands for these can be pretty much anything.

However, if you write code for the 6502 processor, the instruction is written as EOR, not XOR. So you can have instructions such as:

EOR (loc),Y

Similarly, the instruction is written as EOR when writing code for Motorola processors, such as the 6809 or the elegant 680x0 series. In the case of the latter, you can have operations such as:

EOR.L D2, D7
EOR.L (A0), D0

and by the time you're coding for the 68020 upwards, all manner of complex memory operands as well. In the case of the operands above, a ".W" after the instruction signifies a 16 bit operation, while ".L" signifies a 32-bit operation. You can also have ".B" for 8-bit operations on appropriate operands on this series of CPUs.

I still have the manuals for these, even though I last wrote assembly language code in anger around 1998.

Can anybody explain why Pat's quote by rogue mother is dated February 05, 1975?!
Is there a spanner in the works?  Or am I seeing things?
Hi Val,

You can dismiss the psychiatrist  :D  You weren't seeing things.

I can't tell you how it happened but I can tell you what produced the result. The first line in the code block is what should have been used. Somehow the 6 at the end got deleted to give the third line.

Code: [Select]
[quote author=rogue_mother link=topic=4308.msg66928#msg66928 date=1608244346]
[quote author=rogue_mother link=topic=4308.msg66928#msg66928 date=160824434]

If you copy the text in the code block to here where it will be executed you get -

I hope to see you back at the ranch sometime soon.

There's a reason for those numbers.

The underlying PHP code references the MySQL UNIX_TIMESTAMP() function. A Unix timestamp is a unique integer, consisting of the number of seconds that has elapsed since midnight on 1st January 1970, which was agreed by convention as the starting point for time measurement when the Unix operating system was developed.

However, there's a problem with the existing Unix timestamp, namely that it's an unsigned 32-bit integer. Which means that the largest value it can take is 4,294,967,295. Therefore, the Unix timestamp cannot handle dates beyond February 7th, 2106. If a 64-bit timestamp is introduced, this will allow integers all the way to 18,​446,​744,​073,​709,​551,​615. A 64-bit timestamp will be good all the way to July 21st, 2554 with nanosecond accuracy, and if used only to 1 second accuracy instead, will be good all the way to the year 584,000,000,000 - around 42 times the current age of the universe. That should be future proof enough for most people's needs, though possibly not those of cosmological physicists :)

Those who want to explore arcane time measurements further, can enjoy the age of the universe in seconds. :)

Since rodents have put in an appearance here, I thought I'd mention one that has a truly wonderful name.

Dinomys branickii.

Otherwise known as, wait for it ... Count Branicki's Terrible Mouse.

In its native South America, indigenous peoples call it the Pacarana.

Though at 33 lbs in weight, it's bigger than any mouse most of us are likely to encounter.

Scientists have apparently determined that it belongs properly in the Family Dinomyidae, which translates as "Terrible Mice". Though it's closer to guinea pigs morphologically than true mice.

One of its extinct relatives was much bigger. Namely, the wonderfully named Josephoartigasia monesi, which was, in effect, a guinea pig the size of a Nissan Micra car. Exceptional specimens of that beast had a body mass of 1,000 kg or so. The fossil skull that was found belonging to this animal is nearly 2 feet long. What we have here is a rodent whose skull is large enough to act as a vivarium for a modern day guinea pig. :)

Bingo. Knew those people would have the answer.

Nice to know I was right on the money with the Family Chrysomelidae too ... :)

Oh, and there are several photos of this species showing teneral adults that have only recently emerged from the pupa, with washed out colours. They develop that intense acrylic blue colour some hours later.

Turns out the Coleoptera specialists at the Natural History Museum have their own Facebook page: you can visit it here.

Post the photo there and see what their experts make of it.

Taking that one to species level is a job for the Natural History Museum.

Though I've determined that it's a member of the Family Chrysomelidae, which should narrow the search down to about, oh, 3,000 species :)
