Sendy, Amazon EC2 t2.micro: 50 emails a second

Screenshot 2017-07-09 10.53.42

Now that my main email group has over 5,000 members I decided to see if I could 1) get Amazon SES to up my sending rate and 2) whether an Amazon EC2 t2.micro could keep up with 50 sends a second.

The previous send rate was 20/sec and it seemed just fine and wasn’t such a problem, but as the list grows 50 seems much useful.

So the good new is that according to watching the status updates as a campaign goes out, and eyeballing the per-second updates, the t2.micro kept up really well and I’ll keep the rate at 50/sec going forward.

So Amazon EC2 t2.micro, and Amazon SES is a really good cheap option for running a decent sized email list.

bash WSL on Windows 10 – what kind of wizardy are you?

Still trying to get my head around what exactly bash on Windows 10 really is. Have read a few posts and watched a few videos, but it is still weird to do a `top’ and see  ubuntu processing running in a command window that in my Windows machine that is running real linux binaries.


But awesome too.

bash windows 10 rsync and ssh like a boss

I was really impressed with the bash WSL on Windows 10 Creators Update. It worked to backup some web sites from Amazon EC2 using the rsync and ssh scripts untouched. I just copied across the ~/.ssh directory and voila! I can now rsync over ssh to pull backups from my web sites down to my windows machine.

This suddenly makes the big honking disk and windows 10 a far more developer friendly machine. Why didn’t microsoft do this years ago?

bash on windows – LAMP stack lives !!


I am becoming more and more impressed with the WSL for Windows 10 Creators Update.

I installed apache and mysql and so far it appears to be working just fine and dandy !!

sudo apt-get install apache2
sudo apt-get install mysql-server
sudo apt-get install php libapache2-mod-php
sudo apt-get install php-mysql
sudo vim /etc/apache2/apache2.conf


Servername localhost
AcceptFilter http none

sudo /etc/init.d/apache2 restart

sudo service mysql restart

and voila!, you have a web server running.

http://localhost is alive.

So it really is behaving like a real ubuntu shell. Wowser. Windows just became more of a developers dream.

Making a WordPress web site disappear

It has come time to make the WordPress sites I made for my kids disappear off the public internet. They are getting old enough that their friends are finding their sites using google searches.

Here is what I did.

  1. Password protect the entire WordPress site
  2. allow a hole in the password protection to allow robots.txt to still be accessible.

If you password protect the whole site, then archived copies of the site will contine to show at the Internet Wayback Machine. So you still need the robots.txt to be accessible, but it should block all web archivers from indexing the site.

Sample robots.txt

User-agent: *
Disallow: /

This tells all web robots to go away, and indeed once this is active, the internet archive stops showing any of the snapshots that it has collected over the years.


I used SiteGround’s cpanel tool to password protect the whole tree containing the blog.

That resulted in the following Sample .htaccess contents

AuthType Basic
AuthName "EP"
AuthUserFile "/home/xxx/.htpasswds/public_html/"
Require valid-user
<Files "robots.txt">
Allow from all
Satisfy any

I added the Files paragraph to allow the robots.txt to be visible. cf;

user@shell: curl
User-agent: *
Disallow: /

So far so good, the site will soon disappear out of Google and be only visible to those to whom I will share the password.

What is the best WordPress Blogging Client?

Here are some links to go with the talk I gave to the July 2016 WordPress Perth meetup that covered WordPress Blogging Clients.

Here is the PDF of the Talk – WordPressBloggingClients.pdf

1. Windows Live Writer


Officially supported as a authoring tool

Can still download and use on Windows 10 as part of Windows Essentials 2012

WLW Introduction

No longer being maintained.

2. Open Live Writer


  • Fork of Windows Live Writer.
  • Open sourced via the .NET foundation.
  • Windows Only
  • Actively developed, but slow updates.
  • Check back in a few months.

3. Desktop (Calypso)


Desktop application for Windows/OSX/Linux that runs very similar code to the `create a new post’ page and other wp-admin pages.

  • Actively being developed, but still in beta.
  • Uses the new WP REST API.
  • Drafts are stored in your wordpress post drafts area
  • Needs the Jetpack plugin to connect your blog to for authentication to work.
  • Faster editing and more convenient that the wp-admin pages to create a new post.

4. Others


  • Great cross platform support and syncing of text between platforms.
  • OCR and Screen grabbing clients etc.

WordPress for Android/iOS.

  • If you can stand typing on a glass screen or an external keyboard then WordPress’s clients for mobile and tablet are an option.
  • Great for uploading photos from your phone for eg.
  • Check to see how well they share drafts and upload media etc.

So Which is Best ?

Start by reading the power point …. and then you’ll realise that there are too many dimensions on any comparison matrix. Ask yourself what is your most important criteria?

  • availability
  • speed
  • support
  • features

For me speed is number 1 and cross platform / sharing drafts is next most important.

Windows Live Writer was FAST for editing, created clean HTML but never was cross platform. Desktop is cross platform, but still kinda slow and a bit clunky, and it tends to butcher the HTML. It does centally store drafts which is a bit plus and enables great cross platform authoring.

So no “1” is best, try them all and see what you like most.
