it can't really be completely lock free because of how it works.
If i didn't have to implement IDictionary/ICollection/et al maybe.
But as it stands, it's got to lock at least sometimes.
The slim r/w lock minimizes actual locking, and my performance tests yield no noticable difference between the thread safe and non-thread safe incarnations.
So unless there's a justifiable need for a lock free dictionary, this is gold plating

Wiped my activated copy of Win10.
Installed Ubuntu.
I had only a slight difficulty installing the NVidia drivers but after that everything works great.
Ubuntu has been running for hours now with no apps crashing and no OS crashes.
I have 30 tabs open in FireFox and one dedicated tab/window streaming YouTube constantly (as a test).
I've installed :
* Anaconda (python dev)
* Visual Studio Code
* Android Studio (running a Android Emulator running Android Pie) and building and deploying apps to the emulator.
My superfast computer (AMD Ryzen 5 2600X 6Core (12 threads)) is actually super fast now.
Goodbye, Windows. It's been an ok 28 years (1991-2019), but you finally completely failed and there is a very valid replacement for you. 
By the way, I paid $138 to activate Win10 Home and Ubuntu was free $$$$.

Only one real reason I use windows.
Visual Studio.
Still the best IDE out there.

Yeah, I will miss it, but the industry has changed so much anyways that 90% of the jobs are related to Web, PWA (Progressive Web Apps), Mobile (Android or iOS).
I am only interested in .NET Core apps now anyways and I will try to figure out how to develop using Visual Studio Code and .NET Core. I'd much rather do Android and iOS now anyways so this will only encourage that is my destination.

If you're not completely against spending money, the Jetbrains Rider IDE runs great on Ubuntu.

VS Code has covered most of the 'coding' grounds. That's turning out to be a panacea for handling code written in any language. But yes Visual studio still has a lot of good project templates that feels juicy to pick and just steer into the work.
VS Code puts you through the installation/set up procedures. But once it's done and we settle with the routine, I think VS Code is great too. (in my limited experience- I'm not a full time dev)
For huge solutions with tons of loaded projects, Visual Studio wins hands down, on any day.
PS: Android Studio has picked up so well too. could be mainly because it's based on Jetbrains.

Vstudio also has a much better interactive editor in terms of flagging source errors and things than Visual Studio Code probably will ever have, due to the differences in how each is designed.
Unless VSCode starts integrating roslyn into their editor.
Plus VSCode AFAIK doesn't really do designer stuff well, if at all.
The plugins i've seen for it anyway, simply don't fill the gap.
But I like it for doing JS and stuff.
And I like it on linux.
But as a sole IDE? I'd miss vstudio too much.

Wow , I missed the whole point of "Visual" studio.
We've been using VSCode only for backend code, like JS and bunch of other languages. But it's all non-gui.
The designer part of VS is huge. Yeah thanks for reminding - Visual Studio is the king. :bow:
btw, I'm not sure why VSCode has to be VScode. it should be just "Studio Code"  , there's nothing really Visual there.

i use the designer a lot whenever i make GUI stuff.
if the HTML designer was better i'd use that too.

Right. The last time I tried to do something with HTML UI, VS was not very cool, but this was so many years back.
Now it's 2019, still things didnt improve?
I guess it's time that most main stream IDEs should keep HTML/WEB UI as their first class citizen for designer interface. WPF , WinForms enjoyed it enough!

To be fair, I haven't found much in the way of a good visual HTML designer. I think it's because CSS layout is so wonky, especially where height is concerned.

I use GEdit on Unix to edit code, it even colours the code in for you like the VS editor does.
And then you tyoe make in a command window.
You can set up a browse with ctags and codequery on Linux, you can even include the kernel/other people source. Makes bug very easy to pin down.
The main thing with Linux is that 'it just works'. From the OS you develop on, to the code you write (in my case Kernel), it just works. None of that jumping through hoops, that appalling circular MSFT documentation.
The only thing I like about writing Windows kernel code is the truly incredible Windbg. If you want a debugger (even for user space code) it is incredible!
(I often us VS to edit kernel code too, then build it with a command line. OK, I know the later VS can build too, but I still use the old WDK)

it's been a long time since i touched the WDK
thank heaven for small favors.
windbg is love. +1 for that.

You may find that Windows 10 runs fine in a VM on that laptop. That is how I run it. You will be using VM's drivers on the bare metal, not Microsoft s. I run it mostly on a desktop with Mint and a MacBook Pro running VMWare.
Probably can't run any mobile emulators. I find that Windows does fine in an external drive on Thunderbolt and "OK" on a USB 3 connected drive. Takes some time to get started but then VS does fine.
That is how I run Visual Studio on Windows. Several choices for free as well.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

The best solution for those in need of VS...
If you add to it the Unity Mode of VMWare (or Seamless Mode of VirtualBox), you actually will not see that virtual machine either...

Unity is no longer available, I think, with VMWare Workstation on a Linux host. At least it was not available when I upgraded to 14 (haven't upgraded to 15 yet). With multiple workspaces on Linux, since forever, I found little use for it and it was always a little buggy here. Some had problems, some didn't. I actually prefer running W10 in a VM installed on ESXi, via remote connect. To each his own. Or is it her own? Whatever.

Oops I feel this is a bit specific to your own current experience? Not sure .
I have both Win 10 & Ubutnu environments. I have it both working great.
I tried to Hyper-v ubuntu on Win10, but the network drivers were making problems rendering internet connectivity too slow to use in the hyper-V-ed Ubuntu. So put it up on a my standby machine. Both doing great.
But I had similar frustrating experience with Windows sometime back. After fiddling with all troubleshoots & hacks, finally I tried replacing my disk to a new one. Problem over. No utilities were pointing out that there was a problem with the disk (HDD). That was my last encounter with a HDD. Now switched all my machines to SSD. And there was another instance where I had a problematic RAM (in desktop), that put me in an assumption that Windows Os was the problem

Welcome to the 21st century!
going to agree with @tLou-Yovin, running windows in VMs takes all of the need-a-graphics-driver hassles away (- it presents a very standard graphics driver that windows handles correctly and still with 2D and 3D acceleration.)
On new processors such as yours (mine's an i5-8600) VM's will start and run as fast as bare metal - no problems (or even hint of slowness) installing and running vs2019 (and older versions) and any other apps.
Bonus: easily separate database/web etc servers to host or/and other VM's which means complete full REAL clients/servers (plurals on purpose) settings all on 1 machine. As good as having your own network of machines. (better, less heat, no need to have a rack in your office)
And I do like linux (I'm also on ubuntu) - for mine:
- linux makes it feel like you are getting your money's worth out of your modern hardware,
- windows (any version) on today's MODERN metal always felt like you were being robbed of the machines potential (because yes, you actually were being robbed - separate topic), ... like owning a jet plane to drive to the shops without ever letting it get up in the air. (wasteful, restricted, cumbersome, messy, ... yes: everything about that picture that's wrong.)

Here's what will happen first thing Monday morning.
Customer calls: "raddevus! You know that old WinForms application that has been running fine without interruption for the past century? Well, we need some changes asap!"
Personally, I haven't had any issues with Windows 10 by the way.

Now install 10 back in a VM on your Ubuntu machine, and see if the original problem comes back. I'm betting it won't.

That's a very cool idea and I do want to try that. Very interesting. Thanks for the idea.
I hope to try that in the future.

Do any of the 3D printer owning people here know of anything that can print a Fusion 360 (.F3D file) Sketch (preferably with dimension lines) or even a DXF file in 1:1 scale?
Everything I find either fails to load, or squeezes it onto a single sheet, buggering the scale.
All I want to do is verify my measurements against the physical object to verify the sizes before I get too far with drawing, extruding, and chopping to fit the printer I'm thinking of buying ... which only goes to 210 x 210 x 200mm.

Don't have a printer, but have you tried the AutoDesk Viewer? It looks like it is free (with an account signup): Autodesk Viewer | Free Online File Viewer. It also looks like it can print to a regular printer, but I'm not sure about that.
