some legacy software checked if the OS name began with “Windows 9” to differentiate between 95 and future versions.
This is a myth. Windows doesn’t even have an API to give you the marketing name of the OS. Internally, Windows 95 is version 4.0 and Windows 98 is 4.1. The API to get the version returns the major and minor version separately, so to check for Windows 95 you’d check if majorVersion = 4 and minorVersion = 0.
Maybe it’s a myth, but it sure sounds plausible. The software that checks the “Windows 9” substring doesn’t even have to exist for this to be reason they chose to skip to version 10 — they just had to be concerned that it might exist.
Sure, maybe there’s no C function that returns the string, but there’s a ver command. It would be trivial to shell out to the command. https://en.wikipedia.org/wiki/Ver_(command)
As what often happens, using \ for paths is for backwards compatibility.
Neither CP/M nor MS-DOS 1.0 had folders. When folders were added in MS-DOS 2.0, the syntax had to be backwards compatible. DOS already used forward slashes for command-line options (e.g. DIR /W) so using them for folders would have been ambiguous - does that DIR command have a /W option, or is it viewing the contents of the W directory at the root of the drive? Backslashes weren’t used for anything so they used them for folders.
This is the same reason why you can’t create files with device names like con, lpt1, and so on. DOS 2.0 has to retain backwards compatibility with 1.0 where you could do something like TYPE foo.txt > LPT1 to send a document to a printer. The device names are reserved globally so they can work regardless of what folder you’re in.
It makes sense why they did it, but their messed up versioning was the cause to begin with. You should always assume Devs will cut corners in inappropriate ways.
I agree, it was mostly a joke. But as the parent commenter explained, “.net is now dot net” is still confusing. They really should just cut ties with the .net name and start fresh. “.net is now MS Interop Framework” or some such. Adopt more sane server versioning moving forward, so searching for information isn’t so wild across all the possible variations and versions of .net, dot net core, dot net framework, asp.net, etc
Sorry, what’s .Net again?
The runtime? You mean .Net, or .Net Core, or .Net Framework? Oh, you mean a web framework in .Net. Was that Asp.Net or AspNetcore?
Remind me why we let the “Can’t call it Windows 9” company design our enterprise language?
But that actually made sense! They care about backwards compatibility.
For those not in the know: some legacy software checked if the OS name began with “Windows 9” to differentiate between 95 and future versions.
The reason they checked that it started with “Windows 9” was because it worked for “Windows 95” and “Windows 98”

Edit: This is the return type from the API: https://learn.microsoft.com/en-us/windows/win32/api/winnt/ns-winnt-osversioninfoexa

vercommand. It would be trivial to shell out to the command. https://en.wikipedia.org/wiki/Ver_(command)This doesn’t prove anything, but there are a TON of examples of code that checks for the substring. It’s not hard to imagine that code written circa 2000 would not be future proof. https://sourcegraph.com/search?q=context:global+“\“windows+9\””&patternType=keyword&sm=0
oh
oh no
There’s code in the JDK that does that??
I really wish I didn’t see that.
Yup!! Never look under the hood in software, you’ll just be disappointed ☹️
I’ve been a software developer for 20 years and this comment is too real. Some days I’m amazed that any software even works at all.
Having worked in both food service and software, I encourage you not to visit the kitchen of any restaurants you enjoy either.

Say whatever you want about Microsoft, but they don’t mess around with backwards compatibility.
It’s easy to be backwards compatible when you’re backwards in general.
I once heard some YouTuber say Windows uses \ in path names instead of / like everyone else because Microsoft thinks backwards.
As what often happens, using
\for paths is for backwards compatibility.Neither CP/M nor MS-DOS 1.0 had folders. When folders were added in MS-DOS 2.0, the syntax had to be backwards compatible. DOS already used forward slashes for command-line options (e.g.
DIR /W) so using them for folders would have been ambiguous - does thatDIRcommand have a/Woption, or is it viewing the contents of theWdirectory at the root of the drive? Backslashes weren’t used for anything so they used them for folders.This is the same reason why you can’t create files with device names like
con,lpt1, and so on. DOS 2.0 has to retain backwards compatibility with 1.0 where you could do something likeTYPE foo.txt > LPT1to send a document to a printer. The device names are reserved globally so they can work regardless of what folder you’re in.Well, better to be backwards with backwards compatibility than to just be backwards.
looks at Apple
Strange argument… how does that prevent checks versus Windows 7, 8 and 1* all of which would be less than 9.
Because it checks if the version starts with the string “Windows 9*”, not wether the number is less than 9.
It makes sense why they did it, but their messed up versioning was the cause to begin with. You should always assume Devs will cut corners in inappropriate ways.
They’ll cut corners the more the shittier APIs and ABIs you provide
The API is fine. It returns the internal version number (which is 4.0 for Windows 95), not a string. https://learn.microsoft.com/en-us/windows/win32/api/winnt/ns-winnt-osversioninfoexa. There’s no built-in API that returns “Windows 95” as a string.
.net core is not a thing anymore in case somebody it’s not aware, now is just .net. (unless you use really old version of course).
But it’s still the core lol
https://github.com/dotnet/core
Well the repo link yes… create a new repo and migrate everything… just so the url doesn’t say core no more it’s quite unnecessary.
And to be honest actual code is currently under https://github.com/dotnet/dotnet The other links is just for news and docs currently.

I scream silently everytime.
May I introduce you to Usb 3.x renaming?
3.0, 3.1Gen1, 3.2Gen1, 3.2Gen1x1 are the 5Gbps version.
3.1Gen2, 3.2Gen2, 3.2Gen1x2, 3.2Gen2x1 are the 10Gbps version.
