Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

Go into your git checkout folder of ipxe.

Save the below file as nic-menu.ipxe.

Build iPXE like this:

cd src && make EMBED=../nic-menu.ipxe && cd ..

Requirements: current iPXE as of 2013-08-01 (for proper behavior of autoboot with a network device specified, netX feature, PCI vendor/device ID display and inc command)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

A non-maskable interrupt (NMI) is an interrupt type which differs from standard interrupt mechanism by enforcing attention from the interrupt processor (usually the CPU).  This solution discusses an NMI is in more depth and how they are handled.

### What is an Interrupt ? ###

Modern systems architecture has created tightly coupled connect between system components.  Work for components can be handed off to a component for completion.  Rather than wait for the component the main CPU can be tasked to do other pending work.

When the component has completed its work it will raise a signal to the main processor.  The main processor considers this signal an "interrupt", as the current work on the CPU will be interrupted immediately   Each component has a number assigned to it.

### Why "mask" an interrupt ? ###
