Building Tensorflow from source on Ubuntu 16.04LTS for maximum performance:

TensorFlow is now distributed under an Apache v2 open source license on GitHub.

On Ubuntu 16.04LTS+:

Step 1. Install NVIDIA CUDA:

To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit as shown:

Profiling performance

Using perf:

$ perf record -g binary
$ perf script | stackcollapse-perf.pl | rust-unmangle | flamegraph.pl > flame.svg

NOTE: See @GabrielMajeri's comments below about the -g option.

My First PANDA

Introduction

Being someone who tries to play a lot with Windows memory, I really wanted to play with PANDA, but I was slightly scared because I'd never touched qemu before - all my experience had been with VirtualBox and VMware.

My goal was to install PANDA into a (relatively) clean install of Debian 8 'Jessie', capture a recording and successfully run a PANDA plugin.

	Byobu is a suite of enhancements to tmux, as a command line
	tool providing live system status, dynamic window management,
	and some convenient keybindings:

	F1 * Used by X11 *
	Shift-F1 Display this help
	F2 Create a new window
	Shift-F2 Create a horizontal split
	Ctrl-F2 Create a vertical split
	Ctrl-Shift-F2 Create a new session

	How to fix “ldif_read_file: checksum error”

	Well, in spite of you did read a banner saying “# AUTO-GENERATED FILE – DO NOT EDIT!! Use ldapmodify.” you ignored it and made some manual modifications in any of the LDIF files in /etc/ldap/slapd.d/.

	Don’t worry it happened to me too :) When you need to quickly setup an openLDAP server for development it is pretty much easier to tweak these files although the recommended way is to use ldapmodify tool. But if you change the LDIF files in cn=config manually, their contents and checksums won’t match, which is not fatal, but is annoying when using tools such as slapcat:

	import pandas as pd
	import numpy as np
	from sklearn.feature_extraction import DictVectorizer

	def encode_onehot(df, cols):
	"""
	One-hot encoding is applied to columns specified in a pandas DataFrame.

	KEYBINDINGS
	byobu keybindings can be user defined in /usr/share/byobu/keybindings/ (or within .screenrc if byobu-export was used). The common key bindings
	are:

	F2 - Create a new window

	F3 - Move to previous window

	F4 - Move to next window

	package main

	import (
	"crypto/tls"
	"crypto/x509"
	"flag"
	"io/ioutil"
	"log"
	"net/http"
	)

	# sort array with regards to nth column
	arr = arr[arr[:,n].argsort()]
