Why, oh why can't the Ethernet graph, in the Performance tab in Task Manager, on a Hyper-V host, show the downloads taking place on VMs it hosts?
Right now my router's bandwidth monitor shows some machine is downloading stuff as fast as my bandwidth allows. I currently (finally) happen to know which machine it is - it's one of my VMs; on it, Task Manager shows the bandwidth being maxed out. Great. At least I know.
Only, Task Manager, on the host, doesn't show any activity. The VM is still ultimately using the same physical NIC to talk to the outside world, so why isn't this being reflected on the host bandwidth usage?
If it did, it would have been a lot easier for me to determine what device, on my LAN, is sucking up all the bandwidth. It would've isolated the VMs from the rest of my devices.
Between my phone, my tablets, my laptops, the system on my desk and my VM host, sometimes it's pretty difficult downright impossible to determine who's hogging (for starters - and then there's the "why")...
We've just started a new month. Already I can see that, since midnight (it's currently 11:00am) I've burned through almost 10GB, and I'm actually not actively downloading anything. These are my devices, left to their own devices (so to speak).

you could ban devices until you narrow it down, but that's inconvenient as hell.
suspect windows. always suspect windows.
maybe try running a comparison machine, not in a VM? is there a way you can sort of stage this fresh hell and try to sandbox it "outside" of a VM on a real machine?
either way it sounds like a huge pain in the backside.
Maybe there's some kind of network monitor tool you can use

thats because VM's communicate to/from the NIC driver, not the host network interface. drivers are not part of the operating system. It's possible for a VM to load a driver for some hardware item [plugged into the host] that the host has no clue about what it is. It's why a say win 7 VM still needs it's own USB 3 drivers to talk to USB 3 ports on the host.
(it makes networking easier for hosts and VM's to talk to each other and the outside world without [lookup/translation] kludgery or some worst case scenario of simulation resulting in TCP packetised TCP packets.) It's made possible if you can recall from computer science the 7 layers of network interface.
(by the way, it's also the reason why VPN's work - they only way some sites can detect VPN's is because they have a list of VPN provider's - not because they can detect the fakery/translations from the data.)
but yes, some other things things complicate that, doesn't work with display, disk, keyboard - partially because those don't have nice i.e. "x layer" interfaces, - the VM has to honor the host's control (consider disk allocation: disk free space tables are cached in host's operating memory, so if a VM wants to grow it's dynamic disk it has to ask the host - otherwise all hell would break loose.)
after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

Hmmm,
IEEE 802.1Q[^]
Right click on the list entry in Hyper-V manager and scroll down to the Network Adapter add a unique "VLAN ID" to each virtual machine. Then you can more easily measure bandwidth from your gateway and identify which virtual machine is generating the traffic.

You need to start adding stuff to CP's Tips & Tricks streams.
Or maybe I should have phrased that "We need you to..."

The grammar for python is ridiculous to me. Significant whitespace being the leading cause of my WTF.
But I just taught myself python so i could try out some particular python code in C#
I'm looking through some examples and i find this gem:
multiple = 1024 if a_kilobyte_is_1024_bytes else 1000
Which presumably means
var multiple = (a_kilobyte_is_1024_bytes)?1024:1000;
WTF
and then there's pass.
Pass seems like it should never exist in any language.
That is all.

Not just "significant whitespace" but "significant matching whitespace".
So two identical seeming lines can be unmatched because one uses TABs and one uses spaces.
Heck, even the editor you use is significant in Python.
I'm becoming convinced that it was designed because the author thought VB wasn't quite "Mickey Mouse" enough.

It's a shame, because there's a lot to like about python but the grammar always turned me off of it.

Like, a keyword?
Maybe it's there to serve as a warning...those who know, should pass on any language that has a "pass" keyword...
|
|

|

Yeah, it's a keyword. It's like a non-op used to cajole the parser into accepting a "statement" where you don't want one. Or at least that's what I've gleaned of it so far. There may be other uses.
In any case, it's ridiculous.

Sounds like Fortran's CONTINUE statement.
Basically a NO-OP.
It was used to help structure loops or it could be the target of a GOTO.

Always be wary of scripting languages.

Some are worse than others. Tcl is far worse than Python.
This is not an objection to your statement. Quite to the contrary. Scripting languages are bad.

I generally am. I haven't found one I like yet.

; The equivalent of Python's pass in C, C++, and C#. Most useful as a loop body when the loop construct does all of the work.

ah, fair enough. Gosh, I don't like the look of it though.

I always feel dirty when there's the need to do that. I usually just unravel the loop construct so there's a loop body.

Same here. I have an inherent distrust of while loops with more than 3 or so condition expressions, and I despise for loops with termination conditions that are unrelated to the iteration.

The Python seems more readable that the statement with a ternary expression. I have just started learning python, but the `if/else` is very clear to me.

The different order of notation doesn't seem that worthy of a WTF. That's just a bit getting used to, nothing more.
The real WTFs with Python I've seen are negative notation for hexadecimal numbers instead of two's complement and the inability to find the entry point in anything remotely complex because Python doesn't have a main method, it's just a script language evaluating from the top. Doesn't help when debugging control flow.

One of my claims to fame is that I've successfully avoided learning COBOL, even though a couple of my positions had me skidding really close to it.
I seem to remember one of the [dis]honorable mentions in the Obfuscated C/C++ Contest was a header file that let you write 'C' in a form closely resembling COBOL. As I recall, it was voted "Worst Abuse of the Preprocessor" that year.
