Linux & Windows partition changes, boot fun

To remove GRUB from the MBR on primary disk in the laptop that hold Windows 7:

• boot with recovery DVD
• get to a command window
• issue commands to re-write the MBR

To write GRUB to the external HD containing Linux Mint:

• Boot Machine off Mint Live DVD (can't use virtual box for this)
• Launch GPARTED to determine disk and partition holding Mint
• Open terminal window
• sudo mount   /dev/sdb1   /mnt
• sudo grub-install /dev/sdb  --root-directory=/mnt

grub probe does report some errors but installation of grub works.

to refresh the grub menu on the external drive (if it needs updating...):

• sudo update-grub

to add an entry for linux into the Windows boot menu (otherwise one needs to get the boot list (f12 at startup)):

•

Powershell (Windows... ugg)

Powershell ISE

Powershell 2.0 was loaded on my Win7 SP1 machine so...

Windows Management Framework 3.0 (includes PS 3.0)

How to determine what version of PowerShell is installed:

ssh Fun, git prompting for a password when trying to push to github ???

Answer to problem is here. I did clone the repo down to local machine from another user on github and then tried to push it to my own new repo on github.

Some good background info on setting up to have multiple SSH keys for multiple services (like bitbucket AND github) is here.

A Basic Node.js site

A basic Node.js site using:

• Mongoose - object data modeling (ODM) library to access a mongoDB data store
• Express web app framework
• Jade template engine
• Connect middleware (cookies, favicon, static files, session management, etc) Note: This is installed by NPM as a dependency for Express.
• twitter bootstrap front end framework
• tbd - login using Google, Facebook, etc (passport?)
• best practices for packages.json (support dev & prod, proper dependency version wild-carding etc.)

Steps:

$ cd ~/dev          (assumes ~/dev exists)

$ express appName   (pick any valid app name)

$ cd appName

edit package.json to include following dependency line

"mongoose": "*"

$ npm install     (install all dependencies)

$ npm start       (just test the server starts and works the ^c out of it)

$ mkdir model     (create a dir to hold model related files)

$ cd model

edit db.js to contain:

var mongoose = require( 'mongoose' );

var todoSchema = new mongoose.Schema({

 item: String,

 complete: Boolean,

 date: { type: Date, default: Date.now }

});

mongoose.model( 'Todo', todoSchema );

mongoose.connect( 'mongodb://localhost/todoDB' );

add to app.js:

, db = require('./model/db')

PyCharm - bought it.

Yes its great and all the free IDE options were lacking somehow so I bought a license. I like it for python and javascript. Lots of useful add-ins for MongoDB, Jade, etc etc.

PyCharm !
