Fixed DB problem

##11:20 Thursday 30 October 2014##

I'm not ~~ready~~ likely to file a bug report, but I had to change a field to UNSIGNED before I could use it in a math operation that resulted in a negative value.

I wasn't trying to store a negative value, just

WHERE 2014 - field > 0

The field was unsigned smallint with value 2015.

Well it's not 100% yet, but at least it's not ridiculously broken.

##12:27pm##

Sweet! Now it's working.

I will probably remove the "description:" meta data (cause I never use it), and eventually I'd like to have default values for year, month, and date fields.

##14:00##

Oh crud; it creates the files in the incorrect directory.

##20:07##

Fixed.

jb lesson this morning

##09:03 Thursday 30 October 2014 JST##

I've been teaching a lesson each Thursday morning for JB at a company office near Kawasaki station. Today new student Yohei arrived, though Chika, one of my "regulars" wasn't there, so still just two students, including Ayano.

tutorial running hakyll for free on aws

##20:20 Thursday 30 October 2014 JST##

These notes should work for *nix, including OS X, which I'm using. Windows users may have to adapt when it comes to local stuff.

Easy as

1. get server with root access
2. set up Nginx on server
3. set up Hakyll locally

##1. sign up for AWS micro (free tier available)##

I will probably go with all their defaults:

####Step 1:####

For this, I'm using Amazon Linux AMI 2014.09.1 (HVM) - ami-b5a7ea85 because it's at the top of the AMI list when creating a new EC2 instance, offers a free tier, and includes Docker, which I've heard about more than twice, but know nothing of it yet.

####Step 2:####

t2.micro (free tier eligible)

####Step 3 (Configture Instance details)####

leave defaults

####Step 4 Add Storage:####

Root /dev/xvda snap-62cf04aa 8GiB ~~Magnetic~~ gp2 Not Encrypted

####Step 5 Tag Instance:####

Anything you like is fine. For me:

Name : hakyll.robnugen.com

####Step 6 Configure Security Group:####

Create a new security group. Any name is fine.

Security group name: hakyll.robnugen.com

Make sure it has the following two rules:

SSH from My IP
HTTP from anywhere

####Review and Launch####

I got a popup saying I can use SSD for free, so I'm selecing that. (I had selected Magnetic in step 4 above)

####Save the PEM####

The very final step results in a popup asking which PEM you want to use to access the server. If you don't have a PEM file, download and save the file in your ~/.ssh directory. After saving, set its permissions to 400:

cd ~/.ssh
chmod 400 your-pem-filename.pem

##2. set up Nginx on server##

####Step 1, connect to server:####

Set up a config file in your local ~/.ssh folder:

cd ~/.ssh
nano config

And make it look something like this:

Host *
ServerAliveInterval 120

Host hakyll
    HostName your.ip.addr.ess
    User ec2-user
    IdentityFile ~/.ssh/your-pem-file.pem

Now, connecting to the server is simple:

ssh hakyll

####Step 2, set up nginx:####

Install nginx on server:

sudo yum update
sudo yum install nginx
sudo chown ec2-user /usr/share/nginx/html

##3. Set up Hakyll locally##

We've done all the groundwork; the rest is easy!

Back on your local computer:

####Step 1:####

git clone git@github.com:thunderrabbit/hakyll-journal.git journal
cd journal
ghc --make -threaded site.hs
./site rebuild
./site deploy

Finished! Check out my journal on your server! Feel free to wipe the sub-directories in ~/journal/post and write your own. ;-)

After each change, you can update the site like this:

./site rebuild
./site deploy
