This guy is in love with Pi, no doubt about it. www.collegehumor.com/video:1948828(It's not on YouTube, so I can't embed it, sorry.) As it turns out, he's not the only one enthralled with Pi. YouTube does have lots of vids about the topic, most of them musical in some form or another. YT's query-results page: www.youtube.com/results?search_query=pi+songI used to have Pi memorized out to 50 digits, and could rattle it off purty-durn quick. Not anymore. Nowadays, I'm lucky if I can say the word "Pi" without having to take an extra dose of Ginko Blow..... Ginger Bukak..... whatever that stuff is.  Enjoy! sumgai |

More Pi trivia...
The "real"(!) value of Pi (although transcendental) that most of us engineer-types know is about 3.141 592 653...
When I was going through (primary) school, we'd often be told that (22/7) was a good value to use for Pi... Equating to 3.142 857, that's in error at the 3rd decimal place.
As I was always into numbers and a slide rule nut (in primary school), I tended to use something a bit more interesting, however...
Take the sequence: 113355
Slice: 113 355
Dice: 355 / 113
...and you get 3.141 592 920 ...which is in error at the 7th decimal place.
Knowing all this, am I more irrational than Pi itself?

My workshop teacher at school told me a principle involving Pi that has guided my entire engineering career.
To estimate the duration of a project, first work out how long you think it should take, then multiply by Pi to allow for going around in circles.
For this purpose, 22/7 works just as well.

And for those of you out there with MIDI sequencer software for synths or drums, drop this Song of PI into it. It's pi out 1024 decimals. Not exactly musical, but Robert Fripp would be proud of you for trying... HTC1 |

VERY into Pi. On a somewhat related note, I am not a fan of violence, and am a Christian, but found this rather funny, on that some site you referred us to originally... www.collegehumor.com/video:1948889(hope I get that to work) enjoy! |

Wow I thought I was the only Guitar Nut that even heard of pi day or π day, if you will. Unlike sumgai, I only memorized π to 20 plus decimal places (at best), which is nothing sensational because the German-born Dutch mathematician Ludolph van Ceulen calculated it to 35 decimal places in 1600: 3.14159265358979323846264338327950288 Did you know Ludolph calculated π to 35 decimal places in 1600? Yeah I ougtta know - I was in 1602 and the racket he made kept me awake all night!! Nothing like humor on π day.  Just one more thing. March 14th is also the birthday of Albert Einstein.  |

Yeppers, it's time to re-awaken an old thread, one that's always appropriate for today, March 14th! HAPPY PI DAY, everyone! The wife and I are munching down on a home-made apple pie right now (well, in a few moments, it's in the oven as we speak). Made it last fall with fresh Granny Smith apples from eastern Washington. We make about a dozen or so each year, freeze 'em, and have 'special desert' days over the next several months.... today being one of those special days. Traditions and all that, doncha know. Hope you're doing roughly the same thing, but don't eat it all tonight, save some for tomorrow - that's when PI becomes larger!!  sumgai |

Reminds me of my old college fraternity- "Eta Kau Pi"  . ozboomer- a callback to years ago: In 1971, the summer before I was to start high school, my father talked me into taking a summer school class on using a slide rule. He insisted that this would be essential to success in any technical field. To say that I was not enthusiatic about spending my summer break in a classroom was putting it mildly, but I dutifully did as dad wanted. The following year, in 1972, HP introduced the first handheld scientific calculator . . .and all the folks making slide rules were soon unemployed. |

Then Microsoft would have problems with every other company using red, blue, yellow orange, and green… it would be quite a massive battle… imo. Including AVG’s Internet Security icon. Ahha! It’s a joke, right? |

I was trying to work out why it was Pi Day, then realised the USA does dates differently to the rest of us. Sadly there is no 31st of April so we don't have Pi Day.
Personally I prefer dates in year-month-day order, as in 2023-03-16 (with leading zeros) since naming files and folders in this way gets an automatic chronological ordering in file explorer.

As for the rest of the world, read on.... You might try using something besides Windows File Explorer. When so asked, Nautilus correctly sorts files by date, but then again you need Linux to run it.  Either that, or we all adopt the Julian dating system.... your call.  HTH sumgai |

Coding Train has for years done special challenges for Pi Day. I missed their post yesterday. Will have to check it out later. thecodingtrain.com/tracks/pi-day . . .Well, today is the Ides of March. Around here we celebrate with a bit of festival of tribute bands. The first time I played in it we chose to cover Big Black (I started bleeding halfway through, which is where my profile pic comes from) and we were so good that we have kept at it playing a show or two a year. This year we’re back in the Ides as the same band but covering songs by the Cure. It’s gonna be horrible. |

You might try using something besides Windows File Explorer. When so asked, Nautilus correctly sorts files by date, but then again you need Linux to run it. You can sort by access/modification/creation/etc. date in Explorer too, but this isn't about sorting by timestamps: it's about aligning chronological order with lexicographic order such that dates stored as text within directory/file names are sorted correctly by default in almost any program. For example my music library is organised into 'YYYY-MM-DD album-title' sub-directories, wherein the date is the release date so doesn't correspond to any attribute of the actual directory. Most-to-least significant ordering also has the benefit of retaining sensible ordering across dates/times with differing specificity without the need to introduce placeholder characters. |

yup. ISO standard dates, the default in every sane database. I freaked out when my colleague used the USA date format, and ... the DB understood it... It shouldn't have, especially when ppl here write in the greek locale's format 16-03-23

I never realised that there was a "right or wrong" way (as in "ISO" decreed) to express the date, but D-M-Y (as in small-larger-largest) instinctively made more sense to me. That said, when I was still gainfully employed, my boss insisted that we write all dates as (eg) 29-Feb-23 or 29/Feb/2023* and this was specifically to avoid confusion with Americans, which of course for us meant Boeing (and rarely MD.) This was also because those companies supplied airplanes right across the planet, so their influence was frequently felt outside of CONUS during the course of our business. It's not a big deal- whilst standardisation would be preferable, (and I'm sorry to say should involve units that are inherently interelated) just like inches and millimetres, pints and litres, or tons and tonnes, any sentient being ought to be able to take it in their stride, and that frankly should work both ways ... "Vivre la différence!"

As an attorney, I have always (40+ years now . . .) only used blue pens to sign documents for that reason. But color copiers have now made that pretty much superfluous anyway. |

As for the rest of the world, read on.... I'm not sure there is a way to express the date 'correctly' and would never suggest my way was the only correct way, we just have different conventions. When speaking I would say " March the seventeenth twenty twenty three" so there is inconsistency there.
I'd like to abandon Windows for Linux, but too many of my essential software packages are unavailable for Linux and we have a family subscription to Office 365 which my wife isn't going to give up in a hurry.

What freaks me out is when people say (out loud) something like “the third of the sixth…” It seems to be more common among a certain set of older Americans, and it takes me way too long to figure out. I asked you for your date of birth, not a fargin math word problem!

I'm not sure there is a way to express the date 'correctly' and would never suggest my way was the only correct way, we just have different conventions The convention here is that many, if not most, long-timers will poke fun at each other. We're known for calling Australians 'upside down', and have many permutations on that bon mot. But yes, we, or at least I, sometimes get carried away, and very occasionally, we'll get a "Whaddya mean" PM from someone who wasn't privy to our little foibles. But the rule here is, be polite, keep it family-oriented, and apologize when someone misunderstands your intent. Other than that, have fun! I'd like to abandon Windows for Linux, but too many of my essential software packages are unavailable for Linux and we have a family subscription to Office 365 which my wife isn't going to give up in a hurry. Have you considered, or have even heard of, "Plays On Linux". This is a sub-system that fairly imitates Windows by redirecting and/or rewriting API calls and such. It's meant more for games, but I successfully run AutoCAD 2019, and one or two other Windows-only programs. Beyond that, and different from a sub-system, is using a Virtual Machine. That's almost as easy as Plays On Linux, and can save a ton of time when things go South. Just be sure to keep your data on a different drive, outside of the VM. (Ask me how I know....) Not to harp on Linux, it has its limitations, to be sure. But it's no longer a geeks-only private club. I consider it at about the point in development where MS-DOS 4.0 came out with a text based 'graphical display', which was nothing more than a menuing system, one that was way overly complicated for the average user. Once set up and personalized for one's particular needs, it was clearly better than the CLI, but getting to that point was a real hair-pulling experience for most folks. cynical1 is using Linux Mint, I'm on Zorin, both of which are Debian/Ubuntu based. pyrroz is using a derivative of, I believe he said BSD, I can't remember. But the fact remains that we don't all use Windows here, so some help is available if you want to fool around with it - just ask! HTH sumgai p.s. I too have to communicate in MS Office formats with various people, and neither LibreOffice nor OpenOffice are up to speed in replicating exactly what can be done in an MS Office product. Not even close, let alone worthy of a cigar. I've not tried other Linux-based Office imitators, as I just took the easy way out and installed VirtualBox. One virtual machine later, cloned from an old laptop, and I can do whatever's needed by using 'the real thing' (Microsoft products).... even though I don't actually have a bootable Windows installation on my machine. |

Now I have too many other things going on and the time needed to get Adobe Premiere Elements, Vectric Vcarve and CamBam to work in a virtual machine would be too much. Years ago I used to build all my own computers, had a dedicated 'play' machine and had to buy a Windows licence for the main machines, but now I'm just using one Dell laptop for everything. I'm trying to limit the number of hobbies I spread my time over and playing with computers is one that has fallen by the wayside. Far more fun cutting up bits of wood to make guitars and clocks!
