On a petty little machine, once every 10th of a second I need to update a graph in real time. Currently it's a graph where each point is a line that starts at the origin and continues to the value, so it is like a line graph but it is all "filled in".
I need to overlay a second graph. I'm connected @ 20Mhz to a display that even if I could figure out how to read from its framebuffer i couldn't do it at the speed necessary to do true alpha blending.
So I'm going to do fake alpha blending.
Each point in the graph will now be a multicolored line, where each line segment is blended to indicate the data point(s) it represents. For example if one dataset was red and the other was blue, where they intersect would be purple.
That means I divvy the line up into 1-2 segments and draw those instead of drawing a single line.
And I should be able to do that every 100ms without dropping frames.
Woo.
The project is starting to get fun.
As an aside, I put my foot down with my client on behalf of our end-end client (I'm kind of in a multi-layered client structure right now. I work for someone and we collectively work for someone else)
He's an electrical engineer, and I enjoy working with him, in part because of that, but I won't let him get his dirty fingers all over my beautiful UI. I told him "less is more" over and over again. Normally I give my clients what they ask for good and hard, but I'm taking a different approach this time because I actually like this project.

Sewerslvt - goodbye[^]
I got to know Sewerslvt somewhere in 2020 during lockdown.
Pretty good stuff, so I shared it with a friend.
I think he listens to it more often than I do, and last week he shared their new album with me (how the turntables!).
Their style is defined as breakcore and drum & bass, so it's pretty eclectic.
I found a definition of breakcore that sums it up nicely: speed, complexity, impact and maximum sonic density.
This track is the last track on the album (aptly titled "goodbye") that sums up the entire album in about 17 minutes.

So basically darkwave!
I've listened to the genre for a while, but can't say I'm still a fan of it...
Nice for an incidental change though

Agreed. Not a total fan myself, but it is interesting and worth a listen.

Do we have any tools packaged with windows 10?
I couldn't find a proper screen recorder.
Google takes me to expensive options.
For mac, it's available
https://support.apple.com/en-us/HT208721[^]
Any similar free tools available for windows?

That's a new one on me. I followed the instructions, hit Win-G and got a little pop-up message that says "You'll need a new app to open this ms-gamingoverlay link". It's got an OK button that is disabled, and nothing else.
Now, I've not clicked a "link", I've pressed a Windows key combination.
OK, so I'll need a new "app" - what one and where do I find it? Or even how do I find what application? (and don't patronise me by dumbing everything down to "apps")
WTF is the point of showing me a dialog with one button that's disabled!?
Until recently, I used my free copy of Jing (from TechSmith) to record voice-annotated movies, which it saved as Flash files. That is, of course, until Microsoft deleted tools for playing Flash - without my consent or notification, on the basis they were "insecure". Including the ones I'd created myself or had proven safe from many years ago.
PS apologies for going off at a massive tangent. But if something's free and "included" with Windows, why doesn't it work????

I've just tried Win-G on W10-Pro and I get a 'Welcome to X-Box Game Bar'. I don't have an X-Box.
For comparison, I've just tried it on W11-Home and that does the same. And I still don't have an X-Box.

It comes preinstalled I believe. No need for an xbox.

That's the xbox gaming bar. Sounds like you might not have it installed or it needs reinstalled or something changed your shortcut keys.
What happens if you click Start and type xbox? You should see the xbox game bar app.

Enabling or disabling game bar makes no odds. Still get that c***y useless, stupid message box.
Don't worry about further advice; I know all I need to know about it now. It's a pile of s**t.

When a multi-billion corporation with the resources of Microsoft even has a development environment that allows the creation of a dialog that has the only button disabled, I think I'm right to be less than impressed. I don't even know if this IS an error. It tells me nothing whatsoever of use and doesn't provide any advice or guidance on where to find further assistance or to help me resolve the problem. The dialog itself is not draggable, does not allow the message to be copied to the clipboard, does not follow acknowledged best practice for message box styling, etc.. etc..
And since we're discussing MS's stupidity at this point, how about the fact that if I search for "install XBox Game Bar" I get to the MS page about XBox Game Bar, with a big button saying "Get" at the right. here[^] If I click on that "Get" button, eventually (i.e. after quite a few seconds) another window opens, with (apart from a slightly different menu) exactly the same logo, heading, text and "Get" button. It's like nothing has happened. WTF is that all about? I have to hit "Get" again which, I assume, downloads the application and then the Get button changes to "Install". When I click on "Install", nothing happens. Absolutely zilch, zero, nada... nothing. The cursor doesn't even change. No new window, no message pop-up, absolutely nothing. There are three dots to the right of "Install", which, if I click, opens a single "submenu" item "Install on my devices". Well, I'm hardly in a position to install on someone else's devices, am I - or is MS security now such that one can install stuff on other people's devices??
Anyway, if I click on that, I get an overlay (NOT a separate dialog box or window, just an overlay with a thin line around it). It's headed "Where do you want to install?". At the bottom are two buttons: "Cancel", and "Install now". Install now is disabled. I would copy and paste the text that explains things (a little) but once again MS have not enabled this functionality, making it so much harder to search for appropriate information. The gist is that I don't have an applicable device linked to my MS account. Seems I need to sign in on a device with my MS account. So, which is it? I don't have a device linked to my account, or I'm not signed in?
This garbage is on the Microsoft Store application. This is supposedly how I'm to install MS products these days. MS are so arrogant / incompetent that this, one of their preferred channels for getting users to install their software, is buggy, unhelpful, inconsistent and seems to despise any would-be user.
Don't get me wrong - I love some MS products. Windows 2000 was great, rock-solid and installed in minutes. Office 2003 gives me everything I need for my productivity applications. And I even quite like VS2015, though it's bloated and unintuitive in many areas. Oh, and I installed the old Calc.exe to replace the abortion that comes with Windows 10.

I'm sure it will amuse you even more that when I click on the first "Get" button, it opens the store (?) with a message "The thing you're looking for isn't here - we probably don't have it, but just in case, try searching for it".
I gave up.

I feel your pain - I've been through similar hoops when trying to download a free program that claims to work on a PC. Trouble is that the Windows Store only downloads to mobile phones, not PCs.

Well, Microsoft does/did have some crappy error messages. One I got when trying to do a Windows 10 update a couple years ago said: "Something happened". That was the total error message, no error codes, no info on what what it might have been working on.
