Review: Sony Xperia Z3 Compact

I seem to continually have dalliances with the Android world. Last year I bought (then sold) a Sony Xperia Z3, then later purchased/returned an LG Nexus 5X. I always seem to end up going back to my trusty iPhone 5, though. There are just enough dealbreakers with any Android phone that make them tough to live with as a daily driver.

Earlier this spring, I was revamping a few of my iOS apps, and figured that since they’re written using JavaScript and published as “apps” in a Cordova wrapper, I might as well try publishing on Google Play as well. I’d returned my Nexus 5X long ago, so started trolling Swappa for a used Android phone. I’d had my eye on the Xperia Z3 compact for a while: its stylish design, coupled with a large screen inside a small(-ish) chassis had me itching to try one out. I grabbed one for a decent price, released my apps to absolutely zero downloads, and then tried using it as my main phone for a bit.

The thing that I love the best about the Z3 Compact is its screen-to-body ratio. The whole device is just slightly larger than my iPhone 5, but the screen is about 33% larger. Watching videos and reading books is much more enjoyable. Plus, since the overall phone size is manageable, you can use it without resorting to the “smartphone claw grip of death.” The body of the phone looks pretty classy as well – I got the black version, which is like the prototypical black slab that all other smartphones descend from. Unfortunately, Sony never evolved its industrial design past the iPhone 4 era: the phone is all glass, save for the plastic sides. I always treated it fairly gingerly, as I was never sure how hard I could set it down without cracking the back.

Unfortunately, the software front is where most Android phones fall down for me. While most of Google’s software is on point (Chrome, Gmail), the Android messaging scene is pretty fragmented. What I want is a Google-endorsed messenger that piggybacks on top of SMS, similar to Apple’s iMessage. The app that might have fit that category (Hangouts) is deprecated, and users are advised to use a standalone SMS app. Rather than double down on Hangouts, Google instead is promoting two new messengers, Allo and Duo, that you’ll have to get all your friends to download in order for them to be useful at all. Blah. At that point I’d rather use Facebook Messenger, which at least most people have installed.

Sony also tries to include a lot of “value-added” software, which is mostly worthless. They have all sorts of extra media apps, but without a compelling syncing solution for my Mac, I didn’t load any music or videos onto the phone’s internal storage. A few bloatware-type apps (AR Fun, wtf) were immediately disabled (can’t delete these apps, of course). I could sign up for a “My Xperia” accout, but it’s not immediately apparent what benefit it would give me, aside from yet another set of account details to remember (cursory internet research tells me it’s similar to Apple’s Find My iPhone).

Dispite these annoyances, the phone was a pleasure to use, once I disabled/ uninstalled offending Sony software. Since I mostly rely on very basic smartphone apps (Maps, Email, Browser, Books), I don’t mind missing out on the hottest new iOS microtransaction bandit, errrr, game.

However, I ended up getting rid of the phone. Since my wife has an iPhone, the lack of iMessage is a real killer. She’d try to send me a video of the kids, and it would be sent as a hyper-compressed MMS. Static images would fare no better. Rather a minor thing, but messaging is the core of my smartphone use.

The other unfortunate thing is that the Z3 Compact has no upgrade path. It shipped with Android 4.4, and has been (slowly) upgraded through Android 6, but it’s anyone’s guess how much longer it will receive updates. While my iPhone 5 is nearing the end of its update life (4 years!), I know that I can buy a new phone with updated internals in the exact same form factor, and have it be supported for another 3+ years. The Z3 Compact has no obvious successor. Sony released the Z5 Compact last year, but it uses the problematic Snapdragon 810 processor, and the US version has its fingerprint sensor disabled(!). The Z5 Compact’s design is also a bit more stodgy. And the Z5 series is the last of the Z’s – Sony’s recent crop of X-series phones are about as forgettable as they come. I don’t want to get too attached to a dying phone.

I guess I’ll appreciate the Z3 Compact for what it was at the time, and hope that one day Apple will release an iPhone 5-sized device with an iPhone 6-sized screen.

Self-Hosted Comments for a Static Blog

Last year, when I ditched my managed hosting, I converted my blog to use Jekyll, a static site generator. At the time I was pretty overwhelmed with all the tasks necessary to move my digital life, and didn’t want to throw “configure PHP/MySQL” onto the pile. Also, much to my chagrin, when I looked over my Wordpress installation prior to exporting its content, I noticed a bunch of suspicious-looking files that could only have been created by script kiddies exploiting Wordpress vulnerabilities. I thought I had been pretty concientious in keeping my instance up to date, but apparently not. So a static site it was.

One of the downsides to a static site is that… it’s static. No comments or any other form of interactivity. At first I tried hooking up Disqus, which I had actually also used in my Wordpress blog, rather than the native comments. Problem is, I dislike Disqus. As with any free service, if you aren’t paying, then you are the product. Managing a Disqus account is annoying, and it’s yet another 3rd party service that gets to track you around the web. So, during a bit of downtime, I created my own basic blog comments app.

It’s a Ruby app written with Sinatra that has two routes: GET and POST. Comments are stored in a SQLite database (I’m not anticipating heavy traffic). Include the client-side script wherever you want your comments to appear in a post. It uses reCAPTCHA for abuse prevention.

I learned a few things doing this project, including how to use nginx as a reverse proxy (only used Apache before), create an Upstart init script (sigh), and deploy a basic Ruby app on a VPS. It’s amazing how much of this stuff you don’t have to do when working at a company with sysadmin folks XD.

It should be fairly easy for anyone to take this code, made a few minor modifications, and run it for their own blog. I would also be happy to answer any questions about getting it up and running… just leave me a comment!

Recurring tasks for your web app?
Use cron + curl.

Work on a web app long enough, and you’ll come across some sort of task that needs to be accomplished by your app at regular intervals. Some examples might include pruning inactive user accounts, sending reminder emails, or running custom analytics.

My first introduction to these sorts of tasks was at a previous job. A Rails app needed to run a task at regular intervals, and used a gem called Clockwork. At first glance, this seems to be a decent solution to the problem – a lightweight Ruby daemon which triggers your code at regular intervals, using a nice DSL. However, after using it for a while, I decided it perhaps wasn’t the perfect tool. First of all, it adds a dependency to your app, and you need to take the time to learn the API and how to use it. You also need to monitor the Clockwork process to ensure that it restarts after a crash. You also need to ensure that the Clockwork process runs on a single app server; otherwise your job will be run multiple times. Plus, it turns out that timezones are hard.

When a recent requirement came up that could be solved by a periodic task, I ruled Clockwork out, and decided to use some other common tools to accomplish the same goal. As you may have surmised, I ended up using cron to invoke curl, and hit a private URL in my app. While I’m sure many folks can point out downsides to such an approach, it has a lot of appeal to me:

  1. Uses very basic, well-understood software that ships with most (all?) Linux systems.
  2. Hits your webapp, so you don’t have to deal with setting up a DB connection pool, logging, etc.

Cron syntax inscrutable to you? A quick Google search should clear it up nicely. Don’t want to expose a sensitive or resource-intensive task via a public URL? Use basic auth to secure it, returning a 404 if the auth is missing. As a bonus, cron will use your systems time, so you don’t have to worry about the scheduled job missing a beat during DST (yes, this did in fact happen to me).

Signup form automation with Selenium

For a recent project, I was tasked with creating a large number of user accounts on various 3rd party websites. Specifically, Spotify,, and Basis. I started off by doing the ol’ copypasta, but after about the third Spotify account, I realized that I was going to go brain dead before finishing them all. Then I remembered Selenium. I had my list of proposed usernames, email addresses, and passwords – why couldn’t I just feed those into an automated browser instance?

Well, the answer is, of course, that I could – with varying degrees of success. For most account-based websites, the general steps you’ll take to create a bunch of accounts is as follows:

  1. Go to signup page
  2. Enter user data
  3. Submit form
  4. Log out

Spotify was the easiest of the three to automate. Their signup form is very basic, with (surprisingly) no CAPTCHA or email validation. The only problem is that when you successfully submit the form, the resulting page automatically prompts a desktop client download. I wasn’t able to quickly find a way to dismiss that, so simply paused my script so that I could manually click “cancel.” Much easier than filling out the form.

require "selenium-webdriver"
driver = Selenium::WebDriver.for :firefox

accounts = [
  # account info redacted...

accounts.each do |account| ""

  driver.find_element(:name, 'username').send_keys(account[:username])
  driver.find_element(:name, 'password').send_keys(account[:password])
  driver.find_element(:name, 'email').send_keys(account[:email])
  driver.find_element(:name, 'confirm_email').send_keys(account[:email])

  driver.find_element(:name, 'dob_month').send_keys(months[(0..11).to_a.sample])
  driver.find_element(:name, 'dob_day').send_keys((1..28).to_a.sample)
  driver.find_element(:name, 'dob_year').send_keys((1950..2000).to_a.sample)
  driver.find_element(:id, 'register-male').click

  driver.find_element(:id, 'register-button-email-submit').click

  # Enough time to manually dismiss client download prompt
  sleep 5 ""
end was a bit tricker, as they include a reCAPTCHA widget in their form. While modern versions of reCAPTCHA look like just a simple checkbox, there is obviously some complex logic going on behind the scenes. As a human, you click their “I am not a robot” checkbox and you’re done. When a script fills out the form and clicks the checkbox element, the checkbox is checked, but an image recognition CAPTCHA is presented. Rather than try to figure out the logic behind triggering the additional level of protection, I simply stopped my script after loading the challenge, and manually clicked through. It was kind of fun, actually, to see the different queries and how fast I could complete them. I suspect the CAPTCHA is triggered by the absense of human-like activities (i.e. normal JavaScript events that would be triggered by a human, like mouseover), but didn’t feel like figuring it out, because I’m lazy.

require "selenium-webdriver"
require "pry"
driver = Selenium::WebDriver.for :firefox

accounts = [
  # account info redacted...

accounts.each do |account| ""

  driver.find_element(:name, 'userName').send_keys(account[:username])
  driver.find_element(:name, 'email').send_keys(account[:email])
  driver.find_element(:name, 'password').send_keys(account[:password])
  driver.find_element(:name, 'passwordConf').send_keys(account[:password])
  driver.find_element(:id, 'id_terms').click

  captcha_iframe = driver.find_element(:css, 'iframe[title="recaptcha widget"]')
  captcha_checkbox = driver.find_element(:id, 'recaptcha-anchor')

  # switch back to the main document

  # Wait until Control+D from user to continue

Basis was the most annoying form to fill out. It’s some sort of terrible SPA, so you have to wait until the DOM content loads before filling in any data. It also has some sort of weird logic that requires each input to be tabbed into, or else it thinks the POST fails when the form is submitted (it’s not, actually). You can also tell it’s some horrible JavaScript form because some input elements don’t actually have name attributes, which also makes them terribly annoying to find/fill out. I ended up enumerating over all the input elements, then trying to differentiate based on a data-bound-to property. The problem was that multiple elements had the same data-bound-to value, so I had to ignore any subsequent elements after the first. This form also asks for a lot more data (name, height, weight, etc.) that I had to generate. That’s why I love Ruby’s Array#sample method.

require "selenium-webdriver"
require "pry"
driver = Selenium::WebDriver.for :firefox

accounts = [
  # account info redacted...

accounts.each do |account| ""

  # It's a stupid Javascript app, so wait until the DOM elements load
  wait = => 10) # seconds
  wait.until { driver.find_element(:name, 'email') }

  # Email
  driver.find_element(:name, 'email').send_keys(account[:email])
  driver.find_element(:name, 'confirm_email').send_keys(account[:email])

  # Password
  driver.find_element(:name, 'password').send_keys(account[:password])
  driver.find_element(:name, 'confirm_password').send_keys(account[:password])

  # Birthday
  birthday = "#{(1..12).to_a.sample.to_s.rjust(2, "0")}/#{(1..28).to_a.sample.to_s.rjust(2, "0")}/#{(1970..2000).to_a.sample}"
  driver.find_element(:name, 'anatomy.dob').send_keys(birthday)

  # Gender
  driver.find_element(:name, 'gender').click

  # Timezone
  driver.find_element(:name, 'settings.timezone').send_keys("(GMT-04:00) New York")

  # Find elements that don't have any sort of queryable attribute
  height_counter = 0
  weight_counter = 0
  elements = driver.find_elements(:css, 'input')
  elements.each do |elem|
    case elem.attribute('data-bound-to')
    when 'n:profile.first_name'
      elem.send_keys(%w(James John Robert Michael William Mary Patricia Linda Barbera Elizabeth).sample)
    when 'n:profile.last_name'
      elem.send_keys(%w(Smith Doe Brown Jones Johnson Miller Davis Wilson Anderson Taylor).sample)
    when 'n:anatomy.height'
      if height_counter == 2
      elsif height_counter == 1
      height_counter += 1
    when 'n:anatomy.weight'
      if weight_counter == 1
      weight_counter += 1

  # Manually submit form, then log out

I’ll probably never have to do anything similar in the near future, but hopefully these examples will help you out if you have a similar (mind-numbing) task in your future.

Review: Nexus 5X

One of the problems with being a technophile is the rapid pace at which new technology is released. It seems that every other day I see something drool-worthy that would make my life immeasurably better, if only I could cram it into my house alongside my other troves of junk. I try to resist these base urges, but don’t always succeed. A few weeks ago I was tempted by Google’s Black Friday sale, and ended up purchasing a new 32GB Nexus 5X for $350 (the same price I paid for a 16GB Nexus 4, three years ago), and figured I’d provide my thoughts regarding one of Google’s newest reference devices.

When reading other reviews before my purchase, I was worried about the “feel” of the phone. It’s made out of plastic, and one reviewer at The Verge mentioned that it felt cheap and “hollow.” Personally, I didn’t experience the same reaction – the phone feels fine to me. It is made out of plastic, which I was worried about. The phones that I’ve used the most in previous years (iPhone 4/5) have been primarily constructed of glass/metal, which are heavy and feel nice. The Nexus 5X is surprisingly light (as you might expect) for being a 5”+ phone, but the matte plastic finish on the back is actually pleasing. To be honest, I think that plastic is a decent tradeoff for a phone these days, even though “premium” phones have metal bodies. The problems with the metal enclosure are weight, as well as the fact that metal interferes with wireless reception. What Apple (and other manufacturers) have done is to make cutouts in the back of the phone. The iPhone 5 had a decent-looking solution for this, which was to use glass panels at the top and bottom of the phone’s back. The glass panels obviously didn’t match at all with the aluminum enclosure, but it looked pretty good. The iPhone 6 family eschews the glass cutouts for plastic lines around the back of the phone, and they look terrible. To be honest, I prefer the solid plastic back of the Nexus – at least it’s a uniform.

The other area where I prefer the design of the Nexus 5X is its camera bump. I guess we’ve reached a point these days where the demands of high-performance camera lenses and thin enclosures mean that camera lenses protrude from the back of our phones. The iPhone 6 has a little nub, which asymmetrically juts out from the upper right side of the phone. The Nexus 5X puts the camera in the center of the body, and the plastic back smoothly rises up around it to create a pleasing beveled effect. Seriously, if you’re going to have the camera extend from the phone’s back, at least embrace it, as opposed to making it look like an embarrassing afterthought.

My last phone was an iPhone 5, so I’ve never used Touch ID. For that reason, I can’t really compare it to Google’s version, which they call Nexus Imprint. The position of the fingerprint reader on the Nexus 5X is OK – yes, you have to pick the phone up in order to use it, but one of the things I like about Android phones is the software buttons, so the sensor had to go somewhere else. The sensor will both turn on and unlock the phone, as opposed to the power button (which shows the lock screen), so it’s nice to have that choice (I use the lock screen for media controls). I will say that once you have a phone with biometric security, it would be hard to go back – it’s obviously super convenient. It’s pretty egregious that Apple has had a lock on this tech for the last two years, but I guess that’s what you get when you buy the company.

USB Type-C. I like it. It’s the future for sure. Reversible connectors are so much better it’s not even funny. But for now, it’s kind of a pain – you’ll have to buy some new cables or adapters. I wanted to do some remote debugging, and was annoyed to remember that I needed to physically connect the phone, and didn’t have a Type-A to Type-C cable. One good thing about the iPhone’s ubiquity is that everyone has a Lightening adapter. You can forget your charger at home and it’s not too big of a deal. If you don’t bring a USB-C cable for your Nexus, you’re outta luck.

As far as the rest of the package, the software is Google. I find that I use Google services a lot more these days, and they have the added advantage of a web-based presence. For example, I can upload a book to Play Books from my computer, start reading, then download the book/pick up where I left off on my phone. I really like the Google Now launcher, which to be honest is still probably the best part of Android phones. There are a few games that don’t have Android ports (Kero Blaster, for example), but I can live without those. I like how Android/Chrome makes web apps more like first-class citizens. In general, the software Just Works.

I have until the end of January to decide whether or not I want to keep the Nexus, but as of right now I’m thinking I’ll stick with it. It does enough of the things I care about well enough for me to be satisfied. At least until I see the next iPhone revision.


I ended up returning the phone. What an anti-climax, eh? I really liked the hardware, and to be honest I kinda like Android’s UI more than iOS. It really came down to two things: slow interface, and bad camera. I kept on experiencing random delays when trying to launch apps, or otherwise interact with the phone. Not terrible, but enough to be on par with my 3 year old iPhone 5. What’s the point of buying a new phone if it performs the same as the old one? The camera was also a disappointment. It took decent shots, but I had two separate instances where I pulled the phone out to take a picture, and couldn’t. The first time, it gave me an error message like “Camera is disconnected.” Um, what? I had to reboot. Second time, the camera app just never started. I had done the ol’ “double-tap power button to wake camera” trick, and it just sat there with a black screen. Both times I missed the shot I wanted; even a slow camera is better than none at all.

I read the other day that Google is publishing an update which supposedly fixes some of the sluggish performance of the 5X. It is tempting, but I’m not sure I want to pay to be a beta tester. Maybe I’ll take the leap again if I can independently verify the fix is, in fact, a fix.
