Greetings Much has been written re/ the smile of Leonardo da Vinci Mona Lisa After viewing a close up at Wikipedia Sfumato - Wikipedia[^] I am more convinced then prior a possible reason for the fascination is a detail I am surprised has not been previously spoken Namely it seems to me the left corner of her smile is higher than the right So her smile is not a smile but a smirk In measuring this w/ a ruler w/ maximum image magnification the "error bars" or uncertainty in the precise location of each corner is greater for her right being centered lower than the center measurement of her left with the result the overall impression is that of a smirk At least to my eye I would be please to know of other's impressions and mesurements - Cheerio

If you look at actual human beings, you will find we are almost never symmetrical: and although da Vinci was an engineer and an artist he almost certainly didn't start measuring his subjects with a micrometer or a vernier gauge!
Instead, he would have painted what looked best - what flattered the subject and created a "right" painting.
You can destroy art by over-examining it*, you know ...
* or even create art where none exists: most "modern art" for example.

I bought this 5.25 inch floppy disk drive EPSON SD-680L from eBay. I looked it today and see its power connector is not the standard FDD power connector.
the rear image is here .
so I try to ask gurus here to see if anyone can recognize this power connector type and data line type(I think 34-pin Ribbon will work)....

That's a standard 5.25 interface. 4pin power, 34pin ribbon data.
3.5 and 5.25 use different power connectors. This one is made by Molex (or at least to their design)

your voltage numbers are absolutely correct. I will buy this adapter. thank you!

there are some old software that are very useful for me, but they are stored in 5.25inch floppy disk. I want to back it up...

I can't speak of Dell's Desktop... but my Dell Laptop of 2011 is still runing perfectly. Back in the day (around 2013, still under warranty) I had a problem with the heat... I called in, it got repaired and never had another issue.

I found this very entertaining! The guy is a great storyteller! It's a long vid that's not so flattering for Dell. HTE can they sell a PC at that price point with any standard/discount components?
It makes me laugh when family/friends ask for advice on buying a new PC. They skip right past the lower priced models insisting that they need that i7 (certainly not AMD!) and 32GB ram for email and surfing the web! My current machine is an off-the-shelf mid-priced Lenovo (desktop) with the only upgrade being the SSD. I've built my own in the past but they've all been rather noisy. This thing is whisper quiet and boots quick enough. Unfortunately though it shows as questionable or not compatible with Win11!

But still pretty dim. He complains when the system he wasted all this money on does not have the features he did not order. Which begs the question why does someone who knows so little want a great powerful tower system in the first place?

I can remember wanting to have a spare desktop system in case my regular system was malfunctioning (this was back before notebooks became both inexpensive and reliable), so I picked a system up on sale at Best Buy that had Windows Vista installed. OH MY, what a POS! 
I bought it just to use while I got my main one repaired (the "repair" was me buying a new motherboard), and once I got my other system up & running, that stayed functioning properly for years. I then got a notebook and put both systems away, and sure enough when I got around to checking them out years later, they were both malfunctioning, so I just took all the good stuff (hard drive, CPU, memory) and threw them away.

This is a load of BS! Over the years I have bought over a hundred Dell desktops and laptops for personal use, family members and previous employers. I have never had any issues!

I have had six Dells at home, and multiple (laptops, desktops, towers) at work. The worst problem I ever encountered was a faulty power transformer, which was replaced (under warranty) in a day. One bad system does not make the entire product line (or the company) worthless.
I always suspect people who do this sort of thing have an ulterior motive.
[edit]
So he spent almost €2,500 on a tower PC and was surprised that it was a big monster, and not a laptop. Obviously too stupid to look at the pictures on the website before putting in his order.
I wonder if he would like to buy London Bridge?

I am still working on my streaming zip library, and after bouncing between other people's implementations and trying to adapt them I settled on one that was already implemented as a coroutine (which is what I needed)
I worked on it for two days, trying to get it to decompress in chunks. I got it to do a whole buffer at a time but I could not work out how to use this scarcely documented decompression coroutine in the popular minizw.h offering so that it would act like the coroutine it was supposed to be.
So eventually, I googled "tinfl_decompress"
Pay dirt! There's a sample of using it. In the comments I note my output buffer has to be at least 32kB - well that explains a lot. 32kB isn't ideal, but I can work with it if i have to.
In the comments it also notes that one of the necessary component structs its using is about 300kB!
300kB is about the amount of *total RAM* I have available on my system.
That's not counting the input and output buffers I need, and heaven forbid the zip contains a JPEG i need to decompress - I'll have no memory left!
So all this code I wrote around this function is bunk.
Fortunately, I found another implementation of a previous C implementation I was using, only someone had ported it to C#. Yay!
And then I realized one of the reasons that's such a boon. NO PREPROCESSOR. There were pages of macros in the original source. It was one of the reasons I didn't want to touch it.
The thing isn't implemented as a coroutine unfortunately, but the code is something that can be followed and adapted.
I've said it before - I love C#. I don't even use it regularly anymore, but it's nice to have around.
Less is more.

I was expecting a waaay shorter post with that headline... But all good and interesting though

I'm about halfway through converting it (in C#) to use a coroutine. God bless C#
I just need to do the state machine for the uncompressed blocks and then I'm golden.
After that, I port it back to C++ =)
Man, I love C#. If you just code such that you don't really rely on the GC the way your code is orchestrated it's cake to port to and from it.
