Upgrading PHP 5.X to PHP 7 on Ubuntu 14.04 / Apache

I upgraded my DigitalOcean droplet today to run PHP 7, after a few hiccups this was the process that worked best for me.

1. sudo apt-get install python-software-properties
2. sudo add-apt-repository ppa:ondrej/php
3. sudo apt-get update
4. sudo apt-get update && apt-get purge php5-fpm && apt-get --purge autoremove && apt-get install php7.0-fpm php7.0-mysql php7.0 php7.0-json php7.0-curl libapache2-mod-php7.0 php7.0-opcache php7.0-xml php7.0-gd php7.0-bz2
5. sudo service apache2 restart

If you are using NGINX, swap step 5 above to:

First udate your NGINX fastcgi_pass directive to: fastcgi_pass unix:/run/php/php7.0-fpm.sock;

then restart NGINX:

sudo service nginx restart

When you are all done type in php -v and it should say you are running PHP 7.

So far I haven’t run into any issues with WordPress or the various plugins I’m running.

There is a very noticeable speed increase across the board with WordPress as well!

Split Testing & the HelloBar

I’ve been using the HelloBar now for a couple months on both my clients sites and my own with great success. If you haven’t heard of it HelloBar is a simple web app that allows you to display a low profile bar on the top of your website (like the one on the top of this website). You can use this area to display small messages to push people to different areas or offers on your site.

I’ve never been one to overplan my marketing messages or copy, preferring instead to throw things against the wall and adjusting until something sticks. I’ve started exploring split testing more, as it’s a great way to compare multiple approaches analytically to get real data on what works and what doesn’t.

Split testing involves testing multiple options and recording the data to see which option preforms the best.

Split Testing the HelloBar

The first thing you need is at least two HelloBars setup in your account. You should create new bars for the test so the HelloBar stats are fresh.

Create your Own Short URLs

Short URL services have become a critical part of sharing links around the web. These services take a long URL like http://markhodder.com/2011/02/create-your-own-short-urls/ and convert it to a smaller URL like http://mah.lt/s/6

Both links point to the same source, one just has fewer characters (17 vs 53)

These shorter links save precious space, which is critical when it comes to sharing them on Twitter. More then just making a link shorter, these services can also collect additional data, every time the link is clicked.

Information like how many people clicked the link, the countries they visited from and the source where the link was clicked. They even make it easy to update a link after it’s been shared. This allows you to point to a new source if the content has moved.

Why not use an Existing Service?

There are plenty of companies out there offering this service for free, or for a small fee so why take the time to create your own URL shortner?

The most obvious reason is that you are at the mercy of the companies you create your links with, if they are down so are your links. Even worse, if the company closes down your links could be gone forever.

Another great reason to create your own service is that you can create a more personal link. Instead of promoting a 3rd party company every time you share a link, you can be promoting your own brand.

Finally with some free tools, it’s relatively easy to get setup and creating your own URLs in no time!

Your computer is out of memory: line 75, 71, 11 etc.

This error seems to be floating around the internet in the last 48 – 72 hours. It effects Windows users using Internet Explorer and has started a long thread over on Facebook.

Apparently it’s being caused by a recent automatic update from Microsoft. There is no fix as of yet, some users report that deleting temporary internet files / cookies and upgrading flash fixes the problem.

A more drastic solution is to modify your registry (warning modifying your registry without knowing what your doing can break things!):

——

To correct this problem, increase the size of the desktop heap: 1. Run Registry Editor (Regedt32.exe).
2. From the HKEY_LOCAL_MACHINE subtree, go to the following key: SystemCurrentControlSetControlSession ManagerSubSystems
3. Select the Windows value.
4. From the Edit menu, choose String.
5. Increase the SharedSection parameter.

For Windows 2000, Windows XP, and Windows Server 2003:
SharedSection uses the following format to specify the system and desktop heaps:

SharedSection=xxxx,yyyy,zzz

Increase the zzz number to “256” or “512.”

I haven’t tested the above solutions as I left the windows world last year and haven’t looked back, good luck!

Dropbox – EASY Online Backup

Up-to-date backups are one of those nagging little things that you know you should be doing, but you never seem to find the time to do. Most people don’t take it seriously until after their first major data loss and they realize it’s start over or pay thousands of dollars to a data recovery service (yes most recovery’s start at $1,000 and up).

Enter Dropbox – seamless, automatic backup’s across computers and platforms (Windows, Mac and Linux). Dropbox has just came out of private beta testing and is now open to the world. Accounts are free for up to 2gb of data and $100 per year for up to 50gb of data (paid accounts coming this week). And if you thought that was good they also have some other great features such as versioning, undelete, photo sharing, web access to files, private sharing of folders among other Dropbox users and public file sharing (even with non-Dropbox users).

The possibilities for this little piece of software are amazing, with Dropbox anyone could easily:

  • Set up a private network with family members to share photos and documents
  • Set up a common drive for remote and virtual employees
  • Set up a home network to share music and photos between computers

This is by far the killer backup application for anyone looking for a feature rich, hands off, cross platform backup system that above everything else… just works.
