A PS/2 adapter plugged into a USB multiplexer causes rollover problems and phantom keypresses. The adapter needs to be plugged directly into a primary USB port on the computer.

Well yeah, but I'm assuming your keyboard isn't NKRO anyway. You can press maybe 3-4 before it drops keys?
NKRO means each key is individually scanned - you can press all of them at once.
I didn't know how important it was until I had a keyboard with it. I no longer drop keys when I type. I got used to this keyboard in half a day, in part because of this. It's just butter.
But you need serious bandwidth for it. USB 1.0 can't do it. USB 2.0 can though. PS/2 can't, AFAIK

Yup, 4 key rollover is all it will swallow and it handles that with grace.
I can barely think or move fast enough to challenge even 2-3 key rollover.
|

I didn't know I was overwhelming my keyboard until I started reading about the phenomenon and then I switched and stopped dropping keys (for the most part. I still typo, but not nearly as much although part of that may be due to the stellar layout of the keys)

With latest c# iteration, instead of x != null , one can write x is not null .
Meh, I initially thought. But then I tried to override the == and != operators and then.. I understood!

So it is becoming more like Python.
|
|
|
|

C# is a language developing faster than other similar languages, by absorbing good ideas from other languages including python. I hope they'll implement embedding from golang (the only good feature of golang worth mentioning AFAIK). In general, with once and if dotnet interactive sufficiently matures, it might very well replace Python as the most used language for scientific computing.

I was thinking Sql Server T-Sql. When checking for null you need to use WHERE A.SomeColumn IS NOT NULL
|
|
|

"X IS NOT NULL" is actually an SQL language standard, not just T-SQL.

An old list of computer hacker terms explained 'COBOL fingers' as fingers worn down to the last joint.

COBOL truly is filth. What was it that Dijkstra said: "The teaching of COBOL cripples the mind and should be regarded as a criminal offence!"

We always used:
ADD Poop TO Diaper GIVING Stench
and for Fortran.

More like Basic ))) I like that.

As a longtime VB developer.. It always makes me smile just a little to watch C# language evolve and become a little more "wordy" with each new version. Having spent my first .NET developer years in a "C# is superior to VB in every way because ......" environment, It warms the heart to see old concepts, syntax, and patterns once viewed as inferior years later turn into evolutionary improvement.
I applaud the change as I can see cases where that could codebases that are extremely data heavy read a little easier. For anyone but the purists anyway. If I were converting legacy VB code to C# "IsNot" to "Is Not" would feel more natural to me.

Looks more like SQL or Basic. I hope this doesn't keep seeping into other statements. Like:
if(myBool is not false) {}
if(thisString does not contain("yipes!")) {}
if(myString contains("hello") then change it to "goodbye".
var myVar = "a variable" END OF STATEMENT
The more "stuff" you add to a statement, the more likely that (1) more mistakes will occur, (2) Intellisense will overflow and stop working, and (3) the compiler will choke to death.

I was going to say more like SQL

...and spice it up with some '?.' and what else.

What happened to 'Keep it Simple'?

Marketing.
They have to motivate selling a newer version.

Yep,
But just imagine how many bugs could be fixed if we just take a break and stop adding more features.

Probably very valid because I believe Microsoft now markets Visual Studio as a product. It has to pay for itself and make a profit. Before I think they were marketing as a tool to increase Windows acceptance. So it was cheaper.

I love deving IoT because of this.

Well,
The boards you play around with are simply too weak to do much of anything but read sensors. I can't find anything I want to use in the IoT world. Any suggestions?
I have about a dozen Arm SBC I do get some use out of some of those for NAS, DNS and time servers.
My next purchase will be a SiFive RISC-V board[^] just to get early exposure to the instruction set.
