kristopolous / tcpdump-on-device.md
Created May 31, 2017 19:45
tcpdump on a device without disk space

On the device to capture from we set up a FIFO that will be pushed off to another device on the network with disk, in this case we are using 192.168.1.11 as the "host"

On the host, we start up netcat that will be pushed into a capture file that we can analyze later, in this instance, we are listening on port 5001 $ nc -l -p 5001 > capture.cap

In a terminal on the device we make a fifo and then push it out over the network through netcat $ mknod /tmp/fifo p $ cat fifo | nc 192.168.1.11 5001

Getting Input to work in laravel5

Laravel 5 decided to remove the global Input class. What are the implications to existing code bases? As usual the answer is "eh who cares? fuck em."

How does a responsible adult deal with a bunch of finickey novelty-obsessed designers who change specs and pull the rug out from you every 6 months?

Unfortunately I have no general answer to this confounding and dumbfounding lack of even the most basic discipline, but in the case of Input I do!

Adding a backwards-compatible Input into your laravel5 project

This can be reliably achieved through middleware.

This probably isn't the "right" way of doing things, but if you are one of those dweebs advocating to break every thing every month then sorry, you don't get a seat at the table.

hn job query search
// Usage:
// Copy and paste all of this into a debug console window of the "Who is Hiring?" comment thread
// then use as follows:
//
// query(term | [term, term, ...], term | [term, term, ...], ...)
//
// When arguments are in an array then that means an "or" and when they are seperate that means "and"
//
// Term is of the format:
// ((-)text/RegExp) ( '-' means negation )
