Just got back from a wonderful trip to South Dakota with Lorrie. I wanted to see Mount Rushmore before it became this:
Today, I was playing with Markdown in a README.md file for a repository and thought it’d be helpful if I could see my changes in real time (this was a junk repo I was going to delete, so I wasn’t worried about a bunch of commits). Just thought I’d blog this for my own future reference.
Create a script to commit changes and reload Safari…
Install fswatch (Mac’s version of inotifywait), a tool to monitor for changes to a file or folder.
brew install fswatch
With the following command, any change to our file will get committed and the page in Safari will be reloaded.
fswatch -o README.md | xargs -n1 ./update.sh
I have always loved Chuck Swindoll‘s famous quote:
“Life is 10% what happens to you and 90% of how you react to it.”
It underscores how so much in life depends on perspective. When I started working in clinic, I was stressed by crunch of chart reviews, seeing patients, answering pages, and writing notes while constantly feeling rushed and falling behind. I would leave clinic exhausted with a hard knot between by shoulders. Then one clinic day, I decided to try an experiment. I would work as effectively as I could, but I would consciously avoid worrying about the chaos around me. Whether or not the charts stacked up, I was going to see people as efficiently and effectively as I could, so worrying about the stack of charts wasn’t going to help. Surprisingly, I accomplished the same amount of work that day (in fact, nothing changed about my clinic whatsoever), but I left clinic completely relaxed. I realized simply changing my point of view could massively reduce my level of stress (and increase happiness).
Today, I listened to a Work In Progress talk from Dr. Rich Frankel at Regenstrief and he mentioned Judy Brown’s “Cone in the box.” What a wonderful lesson in perspective: two people looking at the same object and one sees a circle while the other sees a triangle. Who’s right? Are they both right? Are they both wrong? Not surprisingly, it depends on your perspective.
The next time you find yourself arguing with someone about whether it’s a circle or a triangle, take a moment to realize you might both be right (or wrong, depending on your perspective).
“We don’t see things as they are, we see them as we are.” –Anaïs Nin
For another example of how your perspective can change what you see, wait for a large moon on the horizon and try the One-Eyed Pinky Trick. 🙂
I got an email this morning from Luis in Düsseldorf about a suggestion to improve OpenMRS. I help Luis with his ticket and bring it to the attention of the OpenMRS Google Code-In team. Teenagers from Cameroon, Uruguay, and New Jersey discuss the ticket with a mentor in Indianapolis. No doubt, one of these bright young students will submit a pull request soon.
It’s a small, wonderful world full of awesome people!
Another typical day in the OpenMRS community… 🙂
At the recent OpenMRS Worldwide Summit #OMRS15, I was helping out with the Saptarshi’s introductory tutorial and realized that the OpenMRS Standalone requires Java 7, meaning that it fails to run on Java 8. Yikes! But my Mac runs Java 8. How do I get Java 7 on my laptop without making a mess of things?
jenv to the rescue! jenv provides an easy way to manage multiple Java versions. Not only can you easily switch between Java versions, but you can configure different folders to run specific versions of Java. So, for example, you can run Java 7 for the OpenMRS Standalone and run Java 8 everywhere else.
Step zero. Install Homebrew. I already had this installed. I used to use Macports to install utilities on my Mac, but it was fairly invasive. Homebrew installs most everything under your user account, so it doesn’t mess with Mac’s view of the world and rarely, if ever, requires the use of sudo.
Step one. Install jenv.
brew install jenv
Step two. Install Java 7.
Grab the latest version of Java 7 SDK from Oracle’s Java 7 archive. For me, this meant navigating to the Java SE Development Kit 7u80 downloads, accepting the license agreement, and then downloading and installing from the dmg package for Mac OS X x64.
Step three. Tell jenv about Java 7.
jenv add /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/
If your version number differs, then your command may differ slightly. You can always navigate into /Library/Java/JavaVirtualMachines/ to find your installed version folders.
Now you can navigate into your OpenMRS Standalone folder, set the preferred Java version with a command like:
jenv local oracle64-18.104.22.168
and then execute the standalone with:
jenv exec java -jar openmrs-standalone.jar
I recently decided to try switching from Chrome to Safari for a while… to see if it might buy me a little more battery life on my aging MacBook Pro. One of the immediate drawbacks I discovered was realizing how accustomed I had become to the Tab Stack extension for Chrome. It’s a simple workaround for MRU (most recently used) tab ordering that moves the active tab to the left after a brief delay (the delays lets you scan through tabs without re-ordering them). It’s a bit hacky and I’m sure a lot of people wouldn’t care for the approach, but I’m used to it and immediately noticed its absence in Safari.
I googled around and didn’t find an equivalent extension for Safari… so I made one and submitted it to Apple’s gallery. I’ve added an extra hack to mitigate Safari’s insistence on clearing the address bar when tabs are moved (move new tabs immediately) as a version 1.1.
I use Citrix XenApp to connect to a virtual desktop for hospital apps and, being a keyboard junkie, I prefer to have a hotkey to logout from the Citrix session on my Mac. I keep having to reinvent this, so I’m “microblogging” it for future me.
Right-click on the desktop and create a shortcut
From then on (until the desktop gets reset), pressing ⌘⌥L will logout of Citrix XenApp.
Can you picture a world without tablets, desktops and laptops? It’s only a matter of time.
SanDisk has introduced a 200 GB microSD card. That’s 200 GB in a mere 15x11mm package. With processors like Qualcomm’s Snapdragon 810 and beyond, it’s not hard to imagine reaching a point where your phone can provide all the computing power you need. The phone has several advantages:
Tablets, laptops and desktops (as we know them today) disappear altogether, once your phone, backed by the unlimited resources of the cloud, can provide all the computing power you need. All that is missing are the interfaces to that computing power. Tablets need only provide the convenience of a touch screen interface. Laptops and desktops can be replace with commodity keyboards and monitors, drawing all the computing experience from your phone. I just hope I can get some sleep when the two-finger typist behind me on the plane is using their tray table as a keyboard.
My wife and I take a week vacation around July 4th each year to relax at our cottage in Michigan. Last year, I dipped my toes back into carpentry with mentorship from a kind neighbor and replaced our wood platform. This year I decided it was time to replace our old picnic table. I wanted an octagonal picnic table and settled on plans from Woodcraft Magazine Issue 58: April/May 2014 by Bill Sands (downloaded from Sawtooth Ideas). The deciding factor was Laney Shaughnessy‘s four part Build an Octagon Picnic Table YouTube series detailing each step of the plans. Menards had the cedar wood (16 8-foot 2x6s, 8 8-foot 2x4s, and one 8-foot 2×2), sawhorses, exterior screws, back saw, chisel, pocket hole jig, hand router + 1/4-inch roundover bit, sander, and wood glue. My neighbor had a mitre saw and a cozy garage that helped when it was raining. It took most of the week and I must’ve watched Laney’s videos a few dozen times in the process for guidance and encouragement, but – thanks to Bill Sands’ great plans and Laney Shaughnessy’s awesome videos – I was able to make a nice new cedar octagonal picnic table from scratch:
Apple Pay is nearly perfect. They managed to make payment both simpler and more secure than using a credit card. But Apple left out one critical ingredient:
Most stores have these. Consumers trade some privacy (allowing the store to profile their purchases) in exchange for lower prices. While Google and others may support scanning of loyalty cards, Apple can do it better: support loyalty cards by eliminating them.
When you use Apple Pay at a merchant, the payment screen (as the confirmation appears) could include an option to enroll in the merchant’s loyalty program. If the user opts in, Apple would create a random key for the merchant and share that same key with the merchant each time you make a purchase at their store. The loyalty key would be unique to each consumer/merchant pairing, so different merchants would get a different key for you, but a single merchant could easily track your purchasing behaviors (even if they don’t know who you are). In exchange for opting in, you would enjoy all the merchant’s loyalty benefits.
This would be a win-win-win scenario:
Apple could even facilitate a process where merchants optionally offer greater savings for more information (e.g., within a list of your merchants in the Apple Pay app, you could not only manage your loyalty enrollments, but also share your gender for 5% more discount or share full demographics and get 10% more of the marked price).
Update 15-June-2015: Apple announced that iOS 9 will support loyalty cards. So far, it looks like loyalty cards that are credit/debit cards will be supported, but what about the myriad of loyalty cards that are used in addition to paying (i.e., swipe your loyalty card to get the discounts, then use your credit card to pay). Will Apple support these and, if so, will they be automatically passed in a single payment transaction? Or will they be handled separately requiring two transactions? Currently, many merchants have you swipe your loyalty card up front (before payment) in order to include discounts in the total price. A better approach (for both consumers & merchants) would be to avoid the loyalty card step and present the consumer with two totals: a total price and then the total for loyalty customers. Apply Pay could transmit the loyalty number along with payment to get the discounts and consumers could get their discounts with a single transaction. By associating the loyalty card number (or Apple auto-generating one), consumers would no longer have to carry the extra loyalty card or even deal without it within Apple Wallet after enrollment.
Update 10-January-2016: In November 2015, Walgreens announced it would be the first to incorporate loyalty cards in Apple Pay. Unfortunately, the loyalty card is entered into the phone and used separately, meaning that the user is left to do the work that the phone (i.e., Apple) could be doing. Scanning the loyalty card into Apple Wallet is be a very simple & intuitive way to consent to the loyalty program; that’s perfectly fine. However, Apple should recognize when you use Apple Pay at a merchant for which you’ve registered a loyalty card and automatically send the loyalty card number within the payment process. Instead, the user is forced to make two transactions: first selecting the loyalty card and then selecting the card for payment.
