Switched to Windows.

For many years I have used Apple computers at home and professionally. I have been a champion for their product, for their stability, ease of use, and unix core. However in the last few years I have become increasingly frustrated with them, from the operating system, to the hardware. I have been looking for a way to untangle myself from Apples “ecosystem” for a while now and finally had enough when I purchased a brand new Macbook Pro. It was a terrible machine and was the last straw for me. Time to rip off the band-aid.

So here I am, running Windows 10, and finding that I actually enjoy it. Perhaps it’s because it’s new and shiny, or maybe Windows has just come a long way since I used it seriously. It has not been that painful of a transition either. A lot of work has been done on the tools I use for web development that they are actually well supported on Windows. Microsoft is not “sexy”, or “cool”, or anything like that. But they aren’t trying to be, but they are making things for people to just get to work. I can buy a PC laptop that has a built-in SD reader, USB-3 and USB-C, up-gradable RAM, hard drive expansion, and powerful video cards options. That is no longer an option for Apple (it never really was I guess). Apple does not make computers for “power users”. They don’t make computers for me any more. It is unfortunate, but whatever it is just a tool, and for now I am choosing Windows as it feels like the superior tool.

I pushed Apple super hard at my job, for years, and now that our creative/development team are 100% powered by Apple computer, im out and moving back to Windows. Pretty funny, and I am sure I’ll get some shit for it. All good though.

I don’t want to forget Linux though. I have tried, for years, to use some distribution of a Linux desktop as my daily driver, and it is simply not there. Not for me. Development on Linux is great, but doing anything creative is pretty terrible IMO.

Order Posts via “Weighted Pseudo Randomness”

A request we are getting more often is to show a list of posts, to elevate some of those posts above others, and to show the posts in a random order. Imagine a post type called “Sponsors”. Sponsors are tiered, like “Platinum”, “Gold”, “Silver”, etc. We want the Platinum sponsors to appear before Gold, Gold before Silver, and so on. We don’t want to favor one particular Platinum sponsor though, we want them to be randomized but ordered by the tier.

The number one rule we had for implementing this feature is that we could not break existing WordPress functionality. Meaning, pagination has to work, and any sort of post filtering that existed on the site must also continue to work. An additional requirement is that we could not have duplicate posts show up as we paginated results. Hence, pseudo random.

This is achieved by ordering the result set by a weight value (aka the tier) and then to randomize those results, using the MySQL RAND() method. MySQL’s RAND() method takes an optional $SEED parameter. If we pass the same $SEED value to our query for each request we can maintain the same random order as we paginate through posts. This ensures that we do not have duplicates. I am generating the seed value using “date(‘ymd’)”. The value will change daily, and create a new randomness to the posts each day. Weight is derived from the tier that the posts are assigned. In my case, we use ACF and an ACF field that allows a user to select a single value from a Tier taxonomy. Knowing this, I used the postmeta value of the term id that is selected to get the slug of the term itself. I then used a CASE statement in my query to assign a weight value based on the slug of the selected taxonomy term. Tier1 is assigned 1, tier2 is assigned 2, if there is no term, weight is 9999 (so that these posts always show up after a tiered post). The CASE statement looks like:

In order for this to work we need to JOIN the wp_terms table based on the metavalue of the selected tier taxonomy.

The query basically looks like this when it is compiled (this is a simplified example of how the resulting MySQL query is going to look):

The goal is to make WordPress write this query for us in the loop. We can do this using filters that modify the WP_Query. The first thing we need to do is to be able to identify the WP_Query so that we do not alter _other_ queries on the site. We only want to change the query that loads posts from our custom Sponsors post type. To do this we add a custom query_var to WordPress and then check for that query_var in our wp_query. Add the query var:

We now inject this param into our main query using “pre_get_posts”. We do not want our listing of sponsor posts in the admin area of WordPress to be ordered randomly, so we need to check that we are not is_admin().

This function checks the wp_query object passed to it. If the post type is our custom post type we set the “is_pseudorandom_query” query var to true. With this set we can now setup our wp_query filters. If you are using a custom WP_Query object you can pass “is_pseudorandom_query” as one of the $args:

Now to the WP_Query filters. The three filters we need are posts_fields to add our CASE statement, posts_join to add our custom LEFT JOINS, and posts_orderby to order by our new weight value and then by RAND().

The functions:

In each function we inspect the passed $wp_query object to see if “is_pseudorandom_query” is set. If it is, then we modify the query.

And there it is. We can now order posts by tier, and then randomize each tier.

Change Default Mail Application in OS X without opening Mail.app

Why this is not a setting in System Preferences I will never understand. But this is how OS X is. In order to set the default mail application you have to use Mail.app. My issue here is that anytime there is a mailto link from any application, clicking on said link opens Mail.app instead of Outlook. I have been looking for a way to alter this behavior this from the command-line and as far as I can tell there is no way to do this with a vanilla OS X install. Not unless you want to manually edit plist files.

I have found a thread on the Jamf support forums that lead me to Duti, a command-line tool for setting default applications on OS X. I was not able to build it on my Mac (OS X 10.10.5 with Xcode 7) but was able to install it via brew.

To set the defaults you need to know what the bundle identifier of the target application is. If you do not know what the bundle identifier is you can find it for your application using the mlds  utility.

This will return something like

Now you can run the following to make Outlook the default handler for mailto links:

I do not know if this is a permanent fix or if this needs to be executed on each login. If it is the later then you could easily add it to your bash_rc.

Anyways, super annoying that this is even a thing. The real solution here is to move the setting out of Mail.app and into System Preferences.

Regular Expression of the day

Match generic US phone numbers. Ignore 1-9 repeating (ie: 4444444444, 1111111111, (except 7, we want 7777777777 for testing)). Allow for spaces, no spaces, dashes, or period delimiters.

Of course we _should_ use a standard phone number regex, but this project calls for something unique.

RegEx is weird, but fun.
