Error of % + digits?

[rbowman]

I am still getting acclimated to a smart phone but I've noticed at least in Slack if I enter two spaces it automatically changed the first to a period.

I also understand how cofefe happened.

[rbowman]

It's a waste of a byte, or two bytes for some encodings. A byte here, a byte there and pretty soon you need a 10 TB drive.

I remove them when I find them in a document!

[Chris Green]

That was in the days of mono-spaced text from typewriters. With proportional spacing the 'software' is supposed to give you that extra space after full-stops.

I'm afraid I'm a bit random about double or single spaces after full-stops even though I use a fixed width typeface for these messages.

3 'counts' in the least significant digit.

Say it reads: 1.000

If we simply add the errors (for simplicity)*

The % error gives between: 0.981 and 1.019 (-0.019 & +0.019)

Then 3 counts "out" in the LSD: 0.978 and 1.022 (-0.003 & +0.003)

*Adding the errors is simple but possibly pessimistic. It tends to give a worst case answer. If the errors are orthogonal, you can square the contribution, add then, then square root the answer. This will give a 'tighter' bound.

Sqroot((.019)^2+(0.003)^))= 0.019235 = 0.019 (3dp)

Giving between : 0.981 and 1.019 in this case.

Do you save them to use later? At least recycle them?

And an odd person.

Do you live in the middle of nowhere or something? No burglars?!

[Chris Green]

Just a small village in Suffolk, probably not much useful to steal either. Our TV (while digital and flat screen) is pretty old, our laptops are not state of the art. The cars might be nickable but they have immobilisers of course, we don't lock them either. Etc., etc.

[Ralph Mowery]

The only reason I lock things up is for proof of burglar for the insurance. There is so many windows and doors with glass in my house it would not take much of anything to get in. I am out in the country and not too much around so would be easy pickings.

I even have simple pad locks on my two small out buildings for the same reason.

[Chris Green]

Exactly! Locking is totally pointless from a security point of view and only means you get damage as well as things stolen if the burglar has to break some glass to get in.

It's one of the reasons we don't lock the cars, far less likely to get the windows smashed.

Our garages are actually locked most nights but only because it happens by default with remote control up-and-over doors.

[Commander Kinsey]

Isn't it best to know the absolute worst? When I take a reading, I want to know how high or low it could possibly be. Somebody with your attitude decided it was ok to make double 13A sockets that only take 20 amps total.

[Chris Green]

But rating twin sockets at a total of 20 amps is only an extension of not rating a ring (or other) circuit at the total possible load if 13 amps was drawn at every socket.

[Commander Kinsey]

Me too, whatever happened to Windows phones? At least then it would be similar to the computer and you wouldn't have anything new to learn.

That kinda thing pisses me off, even more so in forums where they do the same with carriage returns. I try to space something out, and they remove some of it. It's worse in Ebay - they remove all carriage returns from conversations etc, so if I enter my address, it all runs together.

I take it you mean his autocorrect? There's been worse, rude words can appear in texts, and what's more, the recipient might realise that the rude word is in your phone's dictionary because you regularly use it!

[Commander Kinsey]

Except it doesn't. See, same spacing as between the words. Not immediately clear at a glance where the sentences are.

Yuck! Why on earth do you use fixed width? The only point in that is for ASCII drawings for electronics etc. Fixed width takes up more room and is harder to read.

[Commander Kinsey]

Text takes up f*ck all space compared to everything else like programs, images, videos.

[Commander Kinsey]

Yet you didn't remove those extra blank lines up there. Those I find really annoying.

[Commander Kinsey]

All electrons are recycled. Just like water.

I often leave the key in the ignition of mine, but then it is 18 years old. Anyway, it gives the police something to do so they stop harassing people for speeding.
