Everyone I know loves a good Apple product-based trivial controversy. There was Antenna-gate, and Bend-gate which happened just last year. Back when the first iPhone came out, Apple dropped the price a few months after release and early adopters were pissed. No one can say if there will be a real issue with the watch, butI figure it would be fun to make a list of potential ones.
Battery-gate (the battery doesn’t last long enough! I can’t wear it to bed!)
Bend-gate 2 (the wristband bends too much! It doesn’t bend enough!)
Snap-gate (the wristband cracks and snaps! WTF is fluoroelastomer anyway?)
Crown-gate (the digital crown breaks off! It spins too fast!)
Siri-gate (random people shouting “Hey Siri!” can control my watch!)
Shave-gate (The Milanese Loop is shaving my wrist hair off!)
Edit: Thought of a couple more this morning:
Left-handed-gate (can’t wear watch on right hand, digital crown doesn’t spin right!)
Sunglass-gate (can’t see the screen while wearing polarized sunglasses at a certain angle!)
White-band-gate (white sport band gets dirty too easily!)
I doubt any of these will happen, though Battery-gate seems most likely. Maybe something completely trivial and impossible to predict will ruin the watch launch. What sort of non-issue do you think will fill up the news cycles?
A few weeks ago, I noticed a tweet from John Sheehan asking if there was an automated tweet -> screenshot tool:
I played around with CasperJS before finding a StackOverflow post that described that I could do all that I wanted in PhantomJS, which CasperJS is built on. I wrote a script that would take a url as an input and spit a png out to stdout. Then I wrote a node web app in Express that could take the url as a parameter and run the script through the child_process.spawn command. I had the express app write the stdout of the child process to a buffer and send it once the script was finished. Done!
I ran into a problem when I wanted to host my app on Heroku. Heroku apparently does not support writing to /dev/stdout, and I only found out about this when my images were being sent as empty files. I looked at some solutions that involved writing to an Amazon S3 bucket, but I didn’t want to incur that much of an operations overhead for something so lightweight.
As a workaround, I found that Heroku does allow writing to /tmp, though any files you throw in there are not guaranteed to remain there after the request is over. For me that’s perfect, since the file only needs to exist as long as the request lasts.
Finally, I threw together an index view with a form and a button that takes a Twitter URL and loads the image into the same view when you click on “OK.” I got a nice theme from here and hardly customized it.
I also figured out how to use the “Deploy to Heroku” feature by adding an app.json file to my git project.
There were a couple of other issues I ran into that I didn’t describe yet, mostly getting PhantomJS 2.0 to run on Heroku (because previous versions don’t render webfonts correctly) and setting up the multiple buildpacks on Heroku. You can see what I ended up using by inspecting the Github project here.
I called the project Audubon after the Audubon Society which is really into birds (get it? birds, tweets?). You can deploy it yourself with this button:
There’s a couple of things I need to wrap up in this project. If anyone wants to they could also fork the project and throw a pull request at me, but I’m planning on doing these eventually:
Make the command line tool better for generating images (right now it just writes to /tmp so I should make that configurable).
Make a bookmarklet so it’s easy to create images from the Twitter website.
Make the web index page look a little nicer
Maybe provide image format and quality options
Ikea Stockholm. The average college student would scoff at such luxury, but as a first-time homebuyer, I wanted the best. When I saw the Ikea Stockholm TV Unit (in walnut veneer), I knew I would have it. The problem was that it never seemed to be in stock.
I must have waited for months, maybe even a year, to see if the unit was available in my Ikea store, but apparently there were production issues. The Ikea phone support was never useful and just told me to check again later. I was stuck waiting it out while my current Ikea (non-Stockholm) tv stand bowed under the weight of my 60″ television.
On a random visit in December, though, my interest was piqued. The “buy” button was actually there on the page! I tried faking an order and got a preliminary ship date! For whatever stupid reason, I thought this meant that the supply issues had been fixed. I delayed. I wanted to make sure the thing would fit in my living room. I missed out. Later that week, when I checked the site, the unit was gone.
I noticed that the website did something weird when I tried buying the tv unit. The “buy” button was still working. The item was added to my cart. But when I tried to enter my address, I would get an error in my cart saying the unit wasn’t available. There must’ve been some issue with their inventory system.
Instead of checking manually every day to see if Ikea had any real stock, I decided to automate the process using a tool called Ghost Inspector.
Ghost Inspector is a service that lets you define actions for a headless (ghostly) web browser to run for you. It’s mostly intended for running tests on parts of your website (like verifying that a user can log in, get some data, not get an error, etc). If you end up changing a part of your website and it breaks another, Ghost Inspector can automate the process of discovering that regression.
As the title of my blog post implies, Ghost Inspector can also tell you when that piece of furniture you want goes back in stock.
To get started, I created a free account on ghostinspector.com. The free tier allows you to run 100 automated tests per month. This was more than enough for me to check Ikea once every day. To create a “test,” you can either download a Chrome extension that assists you in recording a test, or enter steps into the site itself using actions and CSS selectors (you can also use the extension to record a rough version of a test and edit it later, as I did).
This is what my first test run looked like after I recorded the process of adding the item to the cart, entering my address info and trying to check out:
As you can see, the test failed, which is bad, because I was testing to see if the item was out of stock (which I knew was true). The Ghost Inspector recorder picked up that I clicked on a button with a “pressed” state active. Unfortunately, the headless browser doesn’t hover over a button when clicking it, so it didn’t actually see this element and couldn’t click it. I fixed this by selecting the ‘a’ tag with the specific id that I knew would actually add the item to my cart (I also made the browser pause in case something needed to finish loading before hitting the button):
Here’s the screenshot of my successful (empty cart) test:
At the end of the test, I created an assertion that an element with class “#cartTableError” exists, which shouldn’t happen if your cart is full of Stockholm awesomeness and ready to be shipped. With the test running automatically every day, all that was left for me to do was wait until Ghost Inspector emailed me to notify me of the test “failure,” which meant the item was in stock.
The fateful day. I got an email from Ghost Inspector that my test failed. I hurriedly typed “ikea.com” into my browser. The product page slowly revealed itself and I girded my loins for the moment I could click “buy.” But the buy button wasn’t there! The test failed because the website now correctly showed that the item was not for sale. Boo!
I had to write another test. But unfortunately, I couldn’t assert the non-existence of an object. Instead, I faked clicking the buy button (which apparently worked fine) and then tested whether the cart was empty when I clicked to it. The test looked like this:
Apparently this is a stupid test because it is actually still passing. But Ghost Inspector has a feature where it takes a screenshot after every passed test and compares it to the next test. In this case, the screenshot diff test failed and I was notified a few days ago. And it turns out that the tv stand is actually in stock!
I’ve ordered the tv stand and it should be on its way by the end of the month. Many thanks to Ghost Inspector for creating a free tier for this service so that furniture aficionados like me can automate their obsessive compulsive shopping. But in future versions, please support:
More specific selection of css selectors when using the Chrome recording tool
If you’re interested in creating automated tests for your website (or in getting notifications for furniture availability), definitely give Ghost Inspector a shot.
Since I moved to a new home that’s closer to work, I’ve been riding my bike to commute at least a few times each week. My commute to work is very easy as it’s almost completely downhill. I pay for it on the way back, though. I’ve been trying to get healthier, so commuting with my bike has definitely become a priority. In addition to having fun, I’d also like to motivate myself to ride more often and push myself to get better at it (especially the uphill part).
I’ve been using Strava to track my rides, and it turns out that my ride home includes a user-generated segment that automatically tracks my performance when I’m going uphill on Liberty. The first time I rode, it took 10:44 for me to complete. My best time so far is 6:58. The cool part is that I’m able to see the progress I’ve made, and I really do feel accomplished when I beat one of my best times. Here’s the view I’m using to see what my times are:
This isn’t the easiest table to read, but you can see that the dates sort of correlate with my times, as the fastest one is in September and the ones in August are slower on average. While beating my fastest time is a good motivator, it’s not realistic to try and break my record every time I ride. I’d rather see consistent improvement as a motivator.
To visualize this, I decided to grab all of the times by viewing the full leaderboard (with just my results). I gathered the times and dates and thew them into a Google spreadsheet to visualize my trend. Here are the results so far.
Success! It looks like I made some really good progress since I started in July, and my times have been inching downward as I get better at cycling uphill. The times also probably vary a bit because there are some stop signs and a traffic signal within the segment, which can slow me down.
The next problem I wanted to tackle was the data entry bit. Since it’s a pain to update the spreadsheet each time I ride, I wanted to automate the addition of new efforts (the term that Strava uses to describe single instances of activities on a segment). This is where things get interesting.
Because I’m storing the efforts in a Google Doc, and because Strava has an API, I just need to connect the two together. Unfortunately, my go-to choice for this kind of thing, IFTTT, doesn’t have Strava as a channel. Luckily, I can do something similar with Zapier (btw that’s a referral link, so be sure to click it so I can get more tasks), which is sort of like IFTTT but costs money (albeit with a nice free tier) and has more integrations. You can also set up your own integration, which is what I had to do with Strava.
In order to get the list of my efforts on that particular segment, I had to create a few Zapier “triggers.” One to get my Strava user ID (for use in other API endpoints), another to grab my starred segments (so I could specify which segment I wanted to track), and finally a trigger to listen for any new efforts on my commute’s segment (limited to efforts created by me). I also had to post-process the last trigger so that I could get the date in a format that works in Google Spreadsheets. The result looks something like this:
Now, whenever I ride home on my bike while recording the segment with Strava, the effort will be automatically logged and graphed on my Google Spreadsheet! Apparently, I can embed the chart, so here it is!
While the Zapier integration had a somewhat steep learning curve, it’s nice to just set the “zap” and then forget about it. Any new integrations I might need to write will also go much quicker. As always, Runscope was a really useful tool for exploring the Strava API and getting real responses from the API to play around with. Finally, I learned the right way to spell athlete rather painfully (after misspelling athlete_id a billion times and wondering why my request wasn’t filtering correctly)!
I went from seeing some sketchy looking progress in my Strava results table to being able to visualize it on a graph, while also setting the graph up to update whenever I record a new effort! Automation for the win!
If you’re interested in the details of the integration, or if you want to try it out yourself, let me know and I can invite you as a tester. If there’s a lot of interest, I can also go over the creation of the integration, as I ran into a few gotchas while building it.
I finally got the LG G watch that I won in a contest about a week ago. I replaced my Pebble smart watch with the Android Wear device along with using my spare Nexus 5 instead of my iPhone. It’s been about four days or so since I made the switch so I thought I’d write up my impressions.
The LG G watch is one of the two currently available Android Wear devices for purchase. My coworker Jason, who also won a watch in the same contest, got the Samsung model. We both would have rather had the Motorola watch, but it isn’t available until later this summer so Google decided to send us these ones.
The LG watch is not particularly fashionable. It looks like a pretty generic black rectangle with rounded corners. It comes with a pretty neat charging base that you can magnetically attach the watch to. I would’ve preferred some kind of wireless charging, but this gets the job done, and the watch actually charges pretty quickly. The quick charge time is good because the watch only last about 24 hours anyway.
The software for the LG watch is basically an enhanced version of the notification dock in Android. This actually mirrors Google Glass a bit, but the execution is less awkward because you’re not wearing a watch on your face. Each notification that lives on your phone will also appear on the watch. If the notification is enhanced, you might be able to take action on it through the watch. For example, you can reply to a text message or Google Hangout by dictating a message. This is probably the killer app of the watch, though I feel like talking to your watch is still going to be considered antisocial behavior.
Aside from the notifications, you can also tell the watch to take notes, send e-mails, and set alarms. The watch still relies pretty heavily on your Android phone, though. Notes get saved to Google Keep (which I am not really sure is an app that will stick around), and GPS navigation simply opens Google maps on your phone. I’m guessing that in the future the watch will get smarter, but for now I think that’s a pretty decent feature set.
I’ve been toying around with the idea of writing an app that creates a persistent notification that just shows me how late the bus is going to be in the morning. Every morning I check the AATA website to see how it my bus is going to be. The information is contextual and time sensitive, and I only need it for that one time during the day, so it would make sense to make this something that shows up on my watch when I need it and goes away when I don’t. I think that Google Now could do this to some extent, but it’s not smart enough to know that I want to leave 5 minutes before my bus comes around and not when it’s “scheduled” to arrive.
In order to fully test out the Android Wear watch, I took my SIM card out of my iPhone 5S and put it into my Nexus 5. So far the transition hasn’t been too difficult as I mostly rely on Google services anyway. There aren’t really any apps on the iPhone that I haven’t been able to use on my Android phone.
I may have said this before in previous blog post, but I really think that the quality of Google’s services is catching up to the polish of the iPhone. Consider how bad Apple’s online services are, and how good Google’s are. I can live without iCloud and Apple’s email service (does anyone use their .me email as a real email address?), but I am locked into Gmail, both personally and professionally.
I am guessing that Google could increase Android’s marketshare sharply by simply withdrawing support for all Google services on iOS. Meanwhile, Apple is relying more and more on third parties to fill out the expertise that it is lacking (I mean, really, who the fuck uses WebObjects?). I can’t really see a situation in the long term where Apple beats Google on services, either directly or by convincing third party developers to do it for them. As for whether I am actually switching to Android as my main device, I’d need to see what Apple has in store for their next generation. (Sadly, this LG G watch is not nearly awesome enough to make me switch on its own)
On top of the awesome built-in services of Android, the material design stuff coming from them from this past I/O is looking pretty sweet. If Android can give iOS a run for its money in terms of look and feel, and ease of creating really nice custom views and animations, then developers might just defect en masse. I guess the only thing Android needs to do now is get away from Java (if Apple can do this with Swift, then I’m sure Google can figure it out), because developing on it really sucks the joy out of being a developer.
Anyway, enough reverse-fanboying. I think it’s time for the…
While I think Android Wear does a lot of things right, and it has a lot of potential, the watch really isn’t all that revolutionary. To put it in terms of the HBO show SIlicon Valley, it’s not disrupting or making the world a better place through compression algorithms. It also isn’t a particularly stylish piece of metal and glass, so I wouldn’t wear it if it didn’t serve a purpose. Having said that, Google stuff is all about the integrated services, so I am feeling bullish on the fact that Google Now is always getting smarter, and developers should be able to hook into it, giving it a bit more life than it has right now. Would I buy it if I hadn’t won it? Maybe if I was an Android user already anyway, but I tend to buy too many gadgets as it is.
