docker ps | grep 8029

This searches through your docker containers, and finds any that are running on port 8029. The output should look like this:

fec0c35f0b2d directus/directus:latest "docker-entrypoint.s…" 15 minutes ago Up 5 minutes 127.0.0.1:8029->8055/tcp directus-example

In the above example you can see that port 8029 was identified to be in use by the directus-example container. It turns out I did a test install of Directus on that port, and then forgot to delete it.

Stop the docker container:

docker stop fec0c35f0b2d

The container ID (fec0c35f0b2d) used above is from the first command which provided the container ID

Delete the docker container. In my case I no longer needed this Directus container, so I deleted the container too. If you need to keep your container, then just change its configuration to run on a different port that doesn’t clash.

docker rm fec0c35f0b2d

With this complete, I was able to start the Docker container that’s actually supposed to be running on port 8029 with no issues.

In my case I knew that the port would be used by Docker because I use that port range for Docker only. If you don’t know for sure that it’s Docker using the port, then you can use the following to check which service is using the port. Note that you will need sudo access to run this.

sudo netstat -tulpn | grep 8029

The output from this should tell you which service is using that port.

Usually this is a simple fix, just go in and type:

sudo yum install -y php-memcached

However, this time round the above was giving me the following error:

Transaction Check Error:
file /usr/lib64/libhashkit.so.2.0.0 conflicts between attempted installs of libmemcached-last-libs-1.0.18-2.el6.remi.x86_64 and libmemcached10-1.0.16-1.ius.centos6.x86_64
file /usr/lib64/libmemcached.so.11.0.0 conflicts between attempted installs of libmemcached-last-libs-1.0.18-2.el6.remi.x86_64 and libmemcached10-1.0.16-1.ius.centos6.x86_64

After smashing my head against the desk a few times during numerous attempts at installing the module, reprovisioning the vagrant box and anything else I could think of doing to fix it, I tried something that hadn’t occurred to me before; to install the dependency it was complaining about first.

Using the following commands fixed my issue, and should also work for you:

sudo yum install -y libmemcached-last
sudo yum install -y php-memcached
sudo service php-fpm restart


Hope this helps!

Now, there’s a free and open-source JavaScript library called Impress.js (the author says no rhyme intended!) which will blow your mind.  It’s a JavaScript adaptation of Prezi (which uses Flash), which uses CSS3 transforms and transitions to create really cool effects similar to those on Prezi, and on top of that it’s also uses CSS3 3D animations which takes things one-step further and lets you have 3D effects in your presentation too.

The downside is that at the moment it’s only guaranteed to work on the latest versions of Chrome and Safari.  Non-webkit browsers do have a fall-back mode, which is a simple display of the slides but without any of the animation.  It does work with the alpha versions of Firefox 10 and IE10 builds, so once those are out the browser support will be much better.

Whilst the browser requirements may be a deterrent for most folks, it’s amazing to see what can be achieved using CSS3 and maybe highlights the shape of things to come.

It’s certainly worth bookmarking and having a play with.

To use Less on a website you have 2 options:

1. Use JavaScript to compile on-the-fly.  This isn’t really recommended as you’re now relying on JavaScript for your website to look the way it should.  It also creates additional overhead as your page needs to load in the JS file, load your less stylesheet and finally render your stylesheet by parsing it through the Less Javascript library.
2. Compile your Less stylesheet into CSS, and include is as a normal stylesheet.

The compilation method is obviously the best option as you get the benefits of using Less, and then using it as any other CSS stylesheet.

Whilst the compiled method might be great for when you’ve finished developing, during development you’d still have to use the Less JS method or compile your Less file into CSS each time you make modifications, which can easily become tedious.

This is where SimpLESS comes in.  SimpLess is real-time Less compiler.  You simply drag and drop your less file(s) into the app, and it recompiles your Less file into a CSS file every time you save it.

This app is totally free, open-source and available on Windows, Mac and Linux. As well as doing the compilation, it minifies your CSS too saving you precious bytes during HTTP requests.

How It Works

Twipsum allows you to enter a keyword, then it finds Tweets on Twitter based on that word and combines them into paragraphed text which you can copy and paste into wherever you need it.

It’s a nice little spin on the default lorem ipsum text which we’re all probably sick of seeing.  However, bear in mind that some of the content may be a little inappropriate so it’s probably not the best idea to use it for populating a client website.
