There are a lot of great articles around web design and development. Historically I’ve kept track of these in Instapaper or my feed reeder, but that’s not in the spirit of the open web. So, I’ve fired my Tumblr account back up as a way to track them openly. Feel free to follow along at http://gbenedict.tumblr.com.
After upgrading to Yosemite, I was unable to run Apache Solr as it could not find a version of Java installed.
No Java runtime present, requesting install.
I downloaded and installed the latest version of Java 8, but that didn’t work. I removed it and downloaded the latest version of Java 7. Still no dice.
After a bit of digging around, I found a reference to installing Java for OS X 2014-001. While this is Java 6, it fixed my issue and allowed me to start Solr.
It took me about 20 minutes this morning to figure out how to enable 1Password to work in Safari with iOS 8. It’s not obvious. Here’s how to do it.
I recently added a Xantech ML85K IR repeater kit to my theater room. All of my equipment sits in the back of the room and I needed a solution for my remotes to work while pointing them at the screen as one would normally do.
The challenge with this kit is that the IR receiver comes with a standard 1/8″ (3.5mm) stereo mini plug designed to plug right into the 789-44 connecting block. Unfortunately, the cable in only 7 feet long and I needed to run over 30 feet through the walls and ceiling.
In this case I had two options:
- Use a 50ft stereo mini extender cable (or a 20ft and a 10ft)
- Use CAT6 wire
As I already had CAT6 laying around and it was better suited for in wall use, I decided to cut off the end of the IR receiver and splice the wires. The only problem is that Xantech doesn’t provide the mappings between wire color and function. They do however tell us what the tip, ring and sleeve of the mini-jack do.
So to make this work I did the only logical thing: I cut apart the mini jack to figure out the mappings my self. So you have them, here are the mappings:
- Tip > White > Signal
- Ring > Black > Ground
- Sleeve > Red > +12VDC
While this works for the ML85, my guess is that it will work for other Xantech IR receivers as well.
Back in August I did a write up for my company, TGFI, talking about what we did to make BigSouthSports.com handle tens of thousands of concurrent users.
Be it programming or life, you have to push through your comfort zone to expand your capabilities. If you are unwilling to do that, you’ll lead a very unfulfilling life.
It is a fundamental law of nature that to evolve one has to push one’s limits, which is painful, in order to gain strength—whether it’s in the form of lifting weights, facing problems head-on, or in any other way. Nature gave us pain as a messaging device to tell us that we are approaching, or that we have exceeded, our limits in some way. At the same time, nature made the process of getting stronger require us to push our limits. Gaining strength is the adaptation process of the body and the mind to encountering one’s limits, which is painful. In other words, both pain and strength typically result from encountering one’s barriers. When we encounter pain, we are at an important juncture in our decision-making process.
Ray Dalio, Principles
Every day I try to push myself and challenge my beliefs from the day before. The more I read new topics or tackle difficult tasks, the better I feel.
This quote from Steve Jobs has nothing to do with product design and everything to do with moving society forward.
Designing a product is keeping five thousand things in your brain and fitting them all together in new and different ways to get what you want. And every day you discover something new that is a new problem or a new opportunity to fit these things together a little differently. And it’s that process that is the magic.
Don’t rest on your laurels. Keep pushing.
Heroku recently announced that they are changing the way you backup your app’s database. They are deprecating their bundles add-on and have added a new PostgreSQL only backup feature. This is great news as the old bundles method included a copy of your source code as well. In one instance, our backups went from 90MB compressed to just 17MB uncompressed.
Installing the Heroku PGBackups Add-On
First, you’ll need to install the latest version of the heroku gem.
sudo gem install heroku
Next, go into your project directory and install the pgbackups add-on.
heroku addons:add pgbackups
Once installed you can easily make a backup to the cloud.
heroku pg:backups capture --expire
There are two things to note here:
- This backup now happens synchronously instead of in the background. This makes automation much easier as you don’t have to sleep for a few minutes and hope it’s done.
- The ––expire parameter automatically deletes the oldest backup, making historical cleanup a cinch.
Once the backup completes you can fire the download command off. This will get a public url (heroku pgbackups:url) and download it using curl to a directory on your computer. The file is also renamed with a timestamp like 20101213 for easy sorting.
curl -o /MyComputer/Drobo/backups/MyProject/MyProject_pgbackup_`date '+%Y%m%d'`.sql `heroku pgbackups:url`
That’s it. They’ve really done a great job making it easier to backup your database and it works every time.
What else can you do?
For more information, checkout the Heroku documentation on pgbackups. They have a great example at the bottom for transferring your database between production and staging sites, something we do all the time.
