TIL how to check a web page for accessibility.

Fun fact: there are over 100 A and AA errors on these forums.

Today I received a 13" MacBook Pro, with no instructions on how to use, I am not a Mac person.  :twitch:

The equivalent of the CTRL and ALT keys are reversed which really screws up keyboard shortcut muscle memory.  For instance, to copy and paste, you have to think ALT-C and ALT-V instead of just letting your fingers do what they've done for decades and CTRL-C and CTRL-V.

You may notice there is a Delete key, but no Backspace key. The Delete key is the Backspace key.  It's labeled Delete, but functions like Backspace.  There is no Backspace key that functions like Delete.

File dialog boxes are often limited in functionality to the purpose they were opened for.  For instance in a "Save File" dialog box in Windows, you can also rename, copy, move or delete other files, create folders, etc.  On a Mac, you're pretty much limited to saving the file. 

That's what I remember from my brief attempt a few years ago to convert to Mac and the main reasons that conversion failed.

Those things make excellent heat sink risers for PC laptops!

TIL about network rebooters. Some will reboot when links go down, some will reboot a device after every (X) days of uptime.

Handy to have for certain Cisco bugs in ASA code... :smug:

TIL about " | json" on Arista. Use it for show commands and instead of getting the normal text output to read through it will output the data formatted in JSON. Very helpful if you are writing scripts that have to parse the output of show commands. Get rid off all my ugly regex. Now if only it worked on Cisco.

yeah arista is crack for scripters/python junkies though IIRC you can do it now in NX-OS as well (defo can do it in NX-API, duh)

We have some network rebooters on our night shift. Except they just reboot the devices any time there is an issue, and then give up when it doesn't solve the problem.

TIL about port-forwarding. One of our integrators was having issues with an application talking across an internal layer 3 boundary and it turns out the app is designed to broadcast some of the traffic. Then I learned that DHCP relay (ip helper) is just an easy button for port-forwarding of DHCP/PXE broadcast traffic.

That it is indeed. And I learned a few months ago that it's possible to have too many DHCP relays on a system. Usually, customers don't find that out until they've brought up their 20th separate DHCP system, but this one did!

for network performance,  nothing like 20 DHCP servers chatting across the network vying for assigning some IP to a client.

Today (well yesterday)  I re-learned that one cannot ping an ASA inside interface from outside. :(
