@TheveryevilROFLcopter What would you need Read-Input for?

The very evil ROFLcopter

To read input... ?

Because Host cmdlets dont care about pipes

No?

TimmyD

Read-Host is literal interactive input.

The very evil ROFLcopter

And to read input from stdin what is the cmdlet?

TimmyD

$input or $args[] or param()

Not a cmdlet

Ohhhhhhhh

Ohhhhhhhhhhhhhh

Pipelining in PowerShell is different from what you'd expect in e.g., Bash.

Anybody know how to tell a client to cache a large image? Cache-Control headers don't seem to be working the way I expected them to.

@Mego I've asked them publicly.

Why PowerShell is not listed on esowiki? It deserve a place here lol

Maybe do nothing and assume they'll do it on their own?

Caching is one of those things where it's usually the client's job to worry about it, not the server

VTCAKAVSMoACE

@Mego Nope, not happening. ;-;

Dennis

@VTCAKAVSMoACE How are you testing it?

Geobits

Yeah, I can't think of a time I had to tell a client to cache something (esp images). Usually I only mess with that if I need them to not cache.

Anonymous

16:08

@Geobits Exactly. Caching is not the concern of the server - the server's job is simply to respond to requests.

VTCAKAVSMoACE

@Dennis Through Chrome, Safari, and Firefox on Mac OSX Yosemite.

And refreshing. :P

Dennis

Refreshing clears the cache.

Having ~200Mbps internet makes you realize how slow most servers on the internet are.

So while map(print,range(5)) will not print anything, wrapping in a list execute the map

Geobits

@mınxomaτ After spending time looking at FTP servers, I'm surprised 2-5MB is what you consider slow :P

mınxomaτ

FTP is a slow and broken protocol. But the Windows 10 updates are P2P, and I have the full P2P range enabled.

Maybe they should switch from their proprietary crap to torrent.

The very evil ROFLcopter

I don't really see why my message have 1 star...

Geobits

Oh, I didn't know Win10 updates were P2P. Interesting.

@DJMcMayhem print is a function in Python 3. It outputs the arguments to STDOUT and returns None.

@DJMcMayhem Sort of. It's a list comprehension, which has its own quirks. The full syntax for a list comprehension is [<expression> for <iteration variable> in <iterable> (if <condition>)] (using parentheses instead of square brackets to denote optional parts for obvious reasons)

That's roughly equivalent to:

result = []
for var in iterable:

@Cyoce more generally, you can call pretty much every operator as a method

it's just weirder here because the operator itself is normally applied as a prefix

same for 3.~

So you can define logical not, but you can't define truthyness? Ruby is weird
