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

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

	// selection range
	var range = window.getSelection().getRangeAt(0);

	// plain text of selected range (if you want it w/o html)
	var text = window.getSelection();

	// document fragment with html for selection
	var fragment = range.cloneContents();

	// make new element, insert document fragment, then get innerHTML!

	<block type="cms/block" name="block_name">
	<action method="setBlockId"><id>block_code</id></action>
	</block>

	{{block type="cms/block" block_id="block_code"}}

	{{block type="catalog/product_list" category_id="79" template="catalog/product/list_random.phtml"}}

	#!/bin/bash
	# herein we backup our indexes! this script should run at like 6pm or something, after logstash
	# rotates to a new ES index and theres no new data coming in to the old one. we grab metadatas,
	# compress the data files, create a restore script, and push it all up to S3.
	TODAY=`date +"%Y.%m.%d"`
	INDEXNAME="logstash-$TODAY" # this had better match the index name in ES
	INDEXDIR="/usr/local/elasticsearch/data/logstash/nodes/0/indices/"
	BACKUPCMD="/usr/local/backupTools/s3cmd --config=/usr/local/backupTools/s3cfg put"
	BACKUPDIR="/mnt/es-backups/"
	YEARMONTH=`date +"%Y-%m"`
