Perhaps I’m misremembering, but I thought you had purchased two different USB keyboards at the same time. If you had, swapping out the current keyboard in favour of the hitherto unused one would have been an obvious thing to try, and you would no doubt have tried it by now!

Thank you for replying.

You have not misremembered, I did buy several keyboards of two different types, when they were on offer at various times.

This is the one I am using at present.

I think this is the other type.

https://www.tesco.com/groceries/en-GB/p … /308033616

I have not used it at all yet. I just got it as an emergency backup.

Actually it did not occur to me to try it.

The keyboard I am using worked fine on this new computer before and is at this very moment as I am typing this text. The exact same unit, unplugged from one computer, then plugged into the other one.

So it did not occur to me as a keyboard issue.

Perhaps it should.

Herein

This computer, the new computer, the 10 inch screen Hewlett Packard machine running Windows 10S which I am unwilling to unlock to Windows 10.

The old computer, the 14 inch screen Lenovo machine running Windows 10, which has Serif PagePlus X7, the three Affinity apps, version 1; and FontCreator.

----

The old computer is the one with the problems.

In around March 2021 the old computer lost wifi ability, but still worked otherwise. Some readers may remember from the old Serif Lounge that as Currys were not accepting telephone orders due to the pandemic, a local electrician, who had done some electrical work in my home before the pandemic, with whom I was able to discuss the situation over the telephone, ordered this computer over the internet, then upon receiving it, delivered it to me with due social distance precautions. Following advice in the Serif Lounge thread I was able to download from the Lenovo website to the new computer a .exe file that would install the wifi driver software in the old computer, copy the .exe file from the new computer to the old computer using a USB memory stick, run the .exe file and after a reboot the old computer worked again with wifi to the internet.

Readers may remember that the old computer had had keyboard problems and the trackpad click no longer worked, but I have been using a USB full size keyboard and the mouse keys system from that keyboard, though the trackpad movement still works.

In fact, I much prefer the full size USB keyboard and using mouse keys for mouse clicks, so, on the day I set up this new computer I started to use a USB keyboard and mouse keys in preference to using the keys that are on the computer and the trackpad click.

Since that time the on/off switch of the old computer has gone wrong, but I found that I could still get the computer to start up using the NOVO button, a tiny hole that into which a push with a pin starts with a special maintenance menu, though that menu allows normal startup too, so I could use the computer.

----

The present problem.

Unfortunately the casing has come apart near the power switch. There is a gap that can be pushed shut sometimes. I have a small Tesco toolkit and I might be able to try to use pointed nose pliers to get it together again, but before doing that I am asking for advice here please.

The symptoms on the old machine are as follows.

I plugged in this USB keyboard, which worked on the new computer before the test and still works on the new computer now, so not a physical problem with the keyboard. Please note that when all is well, pressing the NumLock key on the USB keyboard has the effect of a green light coming on above the key. Pressing it again, so in use for mouse keys, turns the green light off.

I started the computer using the NOVO button.

Windows 10 started up, showing a picture of some mountains, a message asking if I like the picture or not.

The pointer on the screen moves around properly in response to me moving it using the trackpad.

But the green light will not come up on the keyboard and pressing various keys, for a mouse click, Enter, Esc, and so on has no effect.

I tried the keyboard on both of the two USB ports for that size USB plug. No response.

So does anyone know what is likely to be happening and whether I might be able to fix it please?

It may be that the computer is a write-off, and I accept that I might need to get another computer sometime in order to be able to use Serif software and FontCreator, but nevertheless I would like to get the old computer going again if possible.

I am wondering if the physical problem has the computer "thinking" that it is shut for using the keyboard even though it is not shut for displaying on the screen, or something like that.

Thinking further about this, I am thinking that if a sequence of n flips starts with zero, one, two, or three H then has one and only one more H in it, then the set of all those sequences defines the outer limit of the results of any sequence of n flips, except for the n flip sequences in which there are no H at all after the zero, one, two or three at the start.

Hello Jack, thank you for your interest.

Actually, I had not written it down. I was in bed, I had woken up early, and what with all the snow around and the cold weather, I decided to stay in bed for a while. So I carried out the thought experiments. smile

Then I posted about them in this thread after breakfast.

I approached the thought experiment by consider each of the possible sequences of heads, H and tails T, as if encoded as binary numbers with H=0 and T=1. This because of me being very familiar with four bit binary numbers.

I quickly realized that the direction in which the playing piece is pointing after the four flips of the coin have been acted upon depends solely on how many heads are in the sequence, yet the position of the playing piece after the four flips of the coin have been acted upon depends not only on the number of T results but as to where they are located in the sequence in relation to any H results in the sequence.

So I then considered the sequences in groups, with each sequence in a particular group having the same number of heads in the result.

This was interesting, as patterns emerge.

For example, with four flips of the coin, with one head in the sequence, there are four sequences. Each sequence results with the playing piece pointing North, with the playing pieces located in a diagonal line, at squares (0, 3), (1, 2) (2, 1), (3,0).

If one extends this to n flips of the coin, there are n possible sequences that each have one H and (n-1) T, and the n results are also a diagonal line from the y axis to the x axis.

Going back to four flips of the coin there are six possible sequences that have two and only two heads in the sequence. Pascal's triangle. These six sequences all end with the playing piece pointing West. The playing piece can end up at any one of six places, all in a pattern.

If there are three and only three heads in the four flips sequence then the playing piece ends up facing South, and there is a different pattern.

It is interesting how Pascal's triangle relates to this as the number, n, of flips increases, yet the rotation only has four possible results. For example, when n=4, the sequence of zero H results and the sequence of four H results each upon being acted upon result in the playing piece pointing East.

Yet for n flips, the sequence of zero H results and the sequence of n H results, upon being acted upon only result in the playing piece pointing in the same direction if n mod 4 = 0.

This is becoming fascinating.

I did a thought experiment of considering every case of four flips of the coin.

I then did a thought experiment of what happens in a random walks with n throws if one result is a head all of the rest of them are tails, considering each case of where in the sequence of n results is the head.

I am now considering what happens if there are n throws of the coin and two results are a head and all the rest are tails.

I am trying to solve this by thought experiments, starting with n=2, then proceeding to n=3, n=4 and so on.

I have devised a random walk rule that I hope might be original.

I have not looked at it in any detail.

I am wondering if it might be fun for readers here, including me, to explore together.

I wanted to devise a random walk that happens in a two-dimensional grid of squares, yet only involves flipping one coin.

So, please imagine a grid of squares, with one square labelled as the origin, and x axis and y axis as conventionally, and y very positive being North, so that we can have North, South, east, west and other directions.

There is one playing piece, that is circular and has an arrow drawn across a diameter.

At the start of a random walk the playing piece is in the origin square, with the arrow pointing along the x axis.

A coin is thrown.

If it lands with the head up, then the playing piece is rotated ninety degrees counterclockwise. If it lands with the tail up, then the playing piece is moved one square forward in the direction that the arrow is pointing, drawing a line as it moves showing where it has travelled.

Two basic thought experiment results are that in a unlimited number of throws of the coin if each throw of the coin results in "a head" then the playing piece never moves from the origin square yet rotates upon it. If each throw of the coin results in "a tail" then the playing piece moves along the x axis towards an infinite value of x.

I am wondering if the nature of the rule of the random walk means that some types of drawn path will be much more common than others.

Looking out of the window later, I noticed that someone had walked through the snow that is on the public pavement that runs perpendicular to the far end of my garden path.

It looks like the depth of the snow there is at least 4 inches.

Snow about 2 inches deep here in rural Worcestershire.

There was none yesterday evening.

My estimate based on the thickness of what has settled on the branches of a Lawson Cypress.

Steadily falling. No wind, so not  "bonfire snow" a in little bits swirling around.

Not "parachute snow" as in large pices very slowly falling.

Just "gentle snow", medium size pieces slowly falling, very gradually building up the depth of snow on the ground.

Why did you choose to highlight that particular review, William? The reviewer in question awarded the product three stars, but the surrounding reviews give it a rating of only one star.

My comment was nothing to do with the number of stars.

It was the comment that implied the reviewer opening a bottle of bottled water with his or her remaining teeth. Hopefully intended by the reviewer as humourous. I thought it hilarious. big_smile

So is there enthusiasm for having this party from 8 pm UK time one evening?

Would you want to attend? Either to actively participate or maybe just to enjoy watching.

If so, which evenings would suit or not suit you?

Tesco has a range of "Keep it handy" items.

https://www.tesco.com/groceries/en-GB/s … it%20handy

Each at £1.50, but with a Clubcard offer of any 2 for £2 until 31 December 2022.

Of the Tesco offers of "Any n for whatever cost" format, I have sometimes had the offer more than once in the same order.

So I am having a look through the items, perhaps to get 2, 4, 6, or whatever depending what I choose.

I quite accept that some of them might never get used, but I consider it best to have it available than think at some time "if only I had bought that duct tape when I saw it." smile

For what sort of purposes could the various "Keep it handy" items be useful? Some are quite specific, but some seem more general in their potential applications.

I do remember many years ago when B&Q had lots of boxes of various things at 50p and a lady said that a lot get bought. However, we wondered how many ever got used and how many sat in a drawer and were never used.

However, I got a Tesco 26 Piece Multi-Purpose Tool Set for £6 some time ago and they are still £6, and I have used something from it several times for various things, including once using the cutters to cut some picture-hanging wire.

A look at some ideas of how in the 1920s the then future would/might look.

As far as I have noticed thus far, nothing about computers and the internet sort of things. Are they sort of looking-back-from-now-retrospectively-implied by the things that are shown? Sort of like a reverse Columbus Egg sort of thing?

It is interesting as to what has happened, what has not happened, and what, like robots, is not how then envisaged but some things have been achieved in different ways. For example the looks almost real robot receptionists that now exist, contrasted with the then envisioned large clearly mechanical robots.

So an 8pm UK time start would seem an inclusive possibility for known forum participants at present as far as I aware. Is that correct?

William

If 11 pm to 7 am local time is regarded as out for everybody, can a time slot be found that is not in that local time period for anybody?

That constraint would mean that the party would not start until after 3 pm UK time so that for Geoff the start would be after 7 am Pacific Time.

So what would 11 pm to 7 am Aotearoa time be in UK time?

Would an evening party from 8 pm to 11 pm UK time work for everybody?
