Who, Me? A Who, Me? second final week launched a much-needed giggle into the lives of no less than just a few finish customers, after a little bit of testing in manufacturing had all too acquainted penalties.
Cuvva is an app-based automobile insurance coverage service. It’s a helpful factor for some — moderately than signing up for an annual coverage, a buyer can use its app to arrange insurance coverage that lasts for simply an hour or so. It might probably additionally push out app notifications, one among which made a programmer’s little joke all too public.

“What may presumably go improper?” requested the programmer (and Cuvva’s lead Android engineer) Adam Bennett. Inside minutes, he had his reply: moderately so much.

Bennett had inadvertently pushed a notification out to 1000’s of the corporate’s Android app customers.
In a “cautionary tale” posted over the weekend, Bennett gave a refreshingly open clarification of how he had “by chance pinged each Android buyer in manufacturing.”
The issue, it appeared, got here from a want to carry the Android app as much as parity with the iOS model by way of push notifications.
“I got down to work out the precise state of push notifications on the Cuvva Android app,” he defined. He picked by way of the code to examine for references to the messaging platform of selection, Firebase Cloud Messaging (FCM), checked the dependency tree for any hidden utilization and took an in depth have a look at the FCM console itself. The latter confirmed iOS (and net) as configured, however nothing for Android.
“At this level I used to be 100 per cent satisfied that there was no method that our Android app may choose up a notification,” he wrote.
So, he did the FCM integration, ready his take a look at message and, certain that no person would ever truly see the notification, despatched out what, looking back, turned out to be a tweet of unalloyed hubris. He then pressed the button.
To be truthful, FCM had warned him that over half 1,000,000 gadgets can be affected (“in hindsight — this quantity did not match our analytics, so the place did it come from? That is proper: registered push tokens”) which gave Bennett somewhat pause for thought. Sadly, nonetheless, not sufficient.
Regardless of his absolute certainty that the message would by no means be seen, roughly 120,000 push notifications had been obtained and round 20,000 had been opened. Oops.
“It was an odd feeling,” Bennett informed The Register, “a mixture of fast dread giving option to humour on the absurdity of what I would executed.” Because the screenshots poured in from amused clients “my horror rapidly turned to embarrassment and amusement.”
However what had occurred? The reply was that whereas the code Bennett checked out was sparklingly clear, the workforce had just lately eliminated a library which included the default FCM service. It had been evaluated and ultimately dropped three weeks prior. Nevertheless, the model of Cuvva’s app in use by nearly all of customers nonetheless had it and push tokens had been quietly registered. Subsequently, that majority of customers obtained a dose of Bennett’s humour.
Fortuitously for the Android engineer, the affect was … fairly good. Clients noticed the humorous aspect and Cuvva’s social media workforce revelled in “probably the most social media engagement we have ever had.”
Certainly, Bennett’s employer was very understanding. “We now have an inside Slack channel,” Bennett informed us, “encouraging the workforce to share errors,” and he highlighted a company tradition that inspired the discussing of cockups moderately than sweeping the smoking stays beneath the closest carpet. “For those who make a mistake as public as this,” he stated, “it is higher to lean into it moderately than cowl it up and try to shift blame.”
It may have been a lot worse had Bennett dropped a swear or two into his “take a look at” (this hack effectively remembers some take a look at information sneaking right into a buyer demo a few years in the past that left a gross sales exec speechless and no less than one programmer jobless) and he had some recommendation on prime of the apparent Do Not Check In Manufacturing.
“Don’t write one thing you would not need clients to see,” he stated. Dropping one thing just like the f-bomb or dishing the dust on firm politics might be severely profession limiting. He went on to level out that “your app just isn’t essentially the shopper’s app” and allotted helpful recommendation regarding notifications and the vetting of libraries.
We’ll give Bennett the final phrase:
“And eventually: Do. Not. Check. Notifications. In. Manufacturing.”
