There are all kinds of old wives’ tales surrounding proper battery use floating around in the popular culture. Things like needing to fully discharge a battery every so often, unplugging devices when they’re fully charged, or keeping batteries in the fridge are all examples that have some kernel of truth to them but often are improperly applied. If you really want to know the truth about a specific battery, its behavior, and its features, it helps to dig in and actually take some measurements directly like [Tyler] has done with a vast array of embedded batteries in IoT devices.
[Tyler] is a firmware engineer by trade, so he is deeply familiar with this type of small battery. Battery performance can change dramatically under all kinds of scenarios, most important among them being temperature. But even the same type of battery can behave differently to others that are otherwise identical, which is why it’s important to have metrics for the batteries themselves and be able to measure them to identify behaviors and possible problems. [Tyler] has a system of best practices in place for monitoring battery performance, especially after things like firmware upgrades since small software changes can often have a decent impact on battery performance.
While working with huge fleets of devices, [Tyler] outlines plenty of methods for working with batteries, deploying them, and making sure they’re working well for customers. A lot of it is extremely useful for other engineers looking to develop large-scale products like this but it’s also good knowledge to have for those of us rolling out our own one-off projects that will operate under battery power. After all, not caring for one’s lithium batteries can have disastrous consequences.
How many people liked your last tweet? Oh yeah? Didja get any retweets? Was it enough to satisfy your need for acceptance, or were you disappointed by the Twitterverse’s reaction?
If you couldn’t see the number of likes, retweets, or followers you had, would you still even use Twitter?
[Ben Grosser] wants to know. He’s trying to see if people will look their relationship with social media squarely in the eye and think honestly about how it affects them. After all, social media itself isn’t the bad guy here—we are all responsible for our own actions and reactions. He’s created a browser extension that demetricates Twitter by removing any bluebird-generated quantifier on the page. It works for tweets, retweets, and the number of tweets playing the trending tag game. Numbers inside of tweets and on user profiles aren’t hidden, however, so you’ll still be able to see, for example, tweets containing Prince lyrics.
The Twitter Demetricator is available as a Chrome extension, and as a userscript for Tampermonkey for the other browsers people actually use (read: no IE support). Here’s what we want to know: Can he gamify it? Can he make a game out of weaning ourselves off of these meaningless metrics and inflated sense of self and FOMO and whatever marketing guff they come up with next to describe the modern human condition? We’re getting low on dopamine over here.
This isn’t [Ben]’s first foray into the social aspects of social media. We covered his Facebook demetricator way back in ’12.

We see [Ben Grosser’s] point that all the metrics found on the Facebook user interface make the experience somewhat of a game to see if you can better your high score. He thinks this detracts from the mission of having social interactions that themselves have a value. So he set out to remove the ‘scores’ from all Facebook pages with a project he calls the Facebook Demetricator.
You can see two UI blocks above. The upper offering is what a normal user will see. The lower is the page seen through the lens of the Demetricator. [Ben’s] feels it doesn’t matter how many people like something or share something, but only that you are genuinely interested in it. With the numbers removed you’re unlikely to follow the herd mentality of only clicking through to things that are liked by a huge number of people. He explains this himself in the clip after the break.
The Demetricator works much like the Reddit Enhancement Suite. It’s a browser add-on for Chrome, Firefox, and Safari that selectively strips out the metrics as the page renders.
