317 5/6 318 4/6, my 90th Wordle. Average 3.8 Aus time is ahead.

Delivery issues are not exclusive to the US. On December 11 one of my monitors failed and after searching for a suitable replacement I ordered two* that afternoon from my usual supplier. *Two, a) to provide a spare and b) because the existing ones were 24" and I could only find 27" at a reasonable price. The order was acknowledged the same day, and their confirmation email said they expected them to leave their warehouse on December 13. But then... Decmber 18. The delivery company finally picked up the monitors from their Melbourne, Victoria warehouse at 1:25pm. December 21. They left Melbourne at 4:03pm. December 22. Arrived in Sydney, New South Wales at... hello, what's this? One arrived at 8:42am, the other at 9:37am!!! They were both delivered later that afternoon, by different drivers, in different trucks, several hours apart.

My wife and I were taking a scenic ferry ride across Sydney Harbour recently. Two Japanese girls seated behind us talking about friends and many other things... some "interetsing". As we were leaving the ferry at the destination I turned to them, greeted them in Japanese and wished them well. The looks on their faces were like what has been described in other replies. Of course they couldn't have known that I worked in Japan for 9 months some 46 years ago.

Thanks, now I see what point you were making. It's reasonably obvious that multiplication and division will usually require truncation or rounding but the addition and subtraction issue (as in your example above) might be less obvious to some. My exchange rate provider supplies the conversion as a JSON string, to six decimal places. Any difference from rounding in this particular app is immaterial. A few hundred transactions in any month, with 20 or so different daily exchange rates. My client needs to know the local currency amount for each transaction, but only the total of all the foreign currency amounts. I am using an OOP language, but probably not one that you use. Delphi (which uses IEEE 754) provides a floating-point function with an Epsilon parameter - the maximum amount by which 2 floating-point numbers can differ and still be considered the same value. I might write, in your example,

if SameValue (c, 0.3, 0.00001) then...

and it would print FOO. Thanks for the ISO 8583 reference. It's long, and has many normative references - I haven't read it all :laugh:

This looks like something I need to know, but I've spent a lot more than 2m and can't find it. ISO 4217 is an obvious place to start but nothing there. Could you provide a link please. Or a search term that would get me there. I do have an app that makes use of 2 (at the moment) currencies - and I'm using FP. TIA.

Guy, I agree. The only possible implementation IMHO. Slacker007 (reply below) shares a Netflix password with his wife. One day, the marriage is falling apart and one party subscribes to every single thing you can with that password, then leaves home just before the first bill comes, never to be seen again. RandMan7557 (also reply below), shares passwords between devs & sysadmins. One day, the whole system is attacked because a digruntled staff member told his mate the hacker the password. Who's guilty? You'll never know.

Interesting that the paper you linked was headed Edgar Dijkstra when his name is Edsger. Maybe Dutch is a bit too hard for the editors at the ACM.

Exactly the same thought process, and I also know the squares in my head - up to 16 anyway. Above that there's a bit of mental arithmetic required.

The other problem is, GMail blocks emails that aren't spam. I used to get 40-50 spam emails a day although it's dropped to 20-30 in CoViD-19. (Why?) Maybe 4 or 5 a week would be emails which should have got through. So I check my GMail spam folder every day.

Your're right. Some years ago a colleague and I were in a cab from JFK to downtown New York. After some time the driver says, "Where you guys from?", to which my colleague answers, "We're from Australia". After a long pause... "Is that down south somewhere?"

Ah, yes. So-called "dress codes" must have exceptions. In a Club of which I was once the Chairman of the operating company, a member was a retired naval commander. One day he brought a colleague as a guest, a still-active naval officer dressed in immaculate white naval uniform, perfectly creased trousers, etc, etc. The bartender of the Members' Lounge refused to allow him entry, as a naval uniform, at least in the Australian navy, does not include a tie. Fortunately the duty manager intervened and all was well.

Fortran didn't require any whitespace. If you were parsing DO2I=1 you might have an assignment statement or, if the next symbol was a comma, a DO loop. How about DO2INUMBR(JPARM1,KPARM2,LPARM3)=LRESLT(MINDEX,INDEX2,INDEX3) You still don't yet know if it's a DO loop or an assignment!

Now there's something us older chaps need, a pubic merkin.

Really useful when you have to restart and you've got 11 open tabs - including this one - and haven't saved the URLs. Restart. Start Chrome. One home-screen tab. CTRL+SHIFT+T. A new Chrome window opens with all 11 "lost" tabs open! Love it!

Thanks Chris. I just tried all the articles from The Daily Build for 25/4. All OK except "A custom WPF slider button" still went to the black hole.

A *lot* of articles in the daily emails these days go to "Error[^]" This one was from the 23/4 (Aus time) email article "Update Checker for Software Update", and many (but not all) end up in the same place.

I once worked with a guy whose surname was Teh, and whatever email client we were using at the time (Outlook I think) would not let me address him correctly in an email.

The way I heard it, one guess is allowed to be wrong, if more than one then all prisoners die. You can't turn around, only see the prisoners in front, can only provide one answer. Very difficult for many, quite simple for those of us who lived in the early days of serial communications and error-prone memory.

The radiation will take care of the genetic engineering :)
