Back in the early days of Docker, I did a whole bunch of work to make WordPress behave as a Twelve-Factor App.

It traditionally hasn't behaved as one – which sort of makes sense, because WordPress grew-up in a world where long-lived servers with writable and persistent local disk storage was commonplace.

I'm sure things have moved on since those days. This was back in 2016. But it sure was a fun challenge!
Explanation:

This is not a good thing - it's an industry mistake. Energy is measured in watt-hours - meaning "a watt for an hour". Watts are (simply put) volts times amps - so, 1 volt at 1 amp is 1 watt; 5 volts at 1 amp is 5 watts; 5 watts for 1 hour is 5 watt-hours. Similarly for amp-hours - 5 amps for 1 hour is 5 Ah (5000mAh).

The problem is, with amp-hours, you don't know the voltage - 20 volts, 2 amp-hours (2000mAh) is 40 watt-hours (Wh). This is where the industry mistake exists - companies labeling things to have a certain number of "mAh" instead of Wh gives completely nonsensical values that can only be relatively compared to each other (sometimes). It's a nightmare for people that actually understand energy capacity and speak and think in watt-hours.

Take that 40Wh / 2000mAh example. Now, imagine it were 5 volts instead of 20 volts - now the same battery becomes 8000mAh. Woaa, so much bigger?? Must be gooder?? No, it's the same battery, just a different voltage - but because you're only looking at one of the two critical numbers (amps, not volts), you see bigger numbers. Given that phones and devices charge at a variety of different voltages, and battery packs have different cell arrangements (in fact, usually 3.7-3.8 volts per cell - what even is the standard voltage reference they're using?), the mAh value has always been meaningless in any context.

Watt-hours, though, are what actually power your devices - laptop batteries hold between 45 and 100 watt-hours, phones between 8 and 15Wh, watches in the <1Wh range, rechargeable mice low 1-2's, power tools in the 60-130Wh (or more) range, and at the very top, EV batteries - which are measured in kWh (kilowatt-hours) - range from 20,000Wh to 150,000Wh. (this is why you never need to worry about charging your phone in your EV... it's like blowing a pinwheel in a hurricane).

I hope the industry stops talking mAh soon - it's seriously getting annoying having to dig through spec sheets to find the actual battery capacity somewhere expressed in watt-hours to know what I'm actually looking at.

I like this in general, but the number of times I've had to delay a release because some non/psuedo-technical person has pulled out "12 factor" like a universal yellow card has been enough for me, overall, to ignore it almost completely. I guess the same has happened to me for "agile" honestly. I recognize the intent of guidelines like these, but they seem to be much more useful to people whose only "value" is to provide ivory tower technical leadership.
if you are not convinced by rational arguments it kinda is useless to discuss this topic anyways, then.

There is no calculation to make. If you have an untreated MRSA infection, you will die. Now whether the treatment can be overly prosecuted is a different question.

Let's say I'm buying a portable power supply for my phone or laptop. I know my device can take a range of input voltages (for my mac: 5V, 9V, 15V, 20V, 28V; for my pixel: 5V, 9V) and know my device will negotiate with the power supply over USB-C for the correct voltage. Since my device can handle either, I would be equally happy with a power supply that used 5V internally as one that used 9V internally. So I do primarily care about the capacity of the power supply in Watt-Hours (energy).

The role used to be called systems engineer, but the HR gods deemed otherwise. Systems engineering is mainly the design, integration and maintenance of complex systems. (Wikipedia). Those tasks are part of the engineering side of sales teams, but not the entirety of the job. A lot involves making the customer aware of a product's capabilities, and so on.
And Ah is a measurement of charge, it reduces to Coulombs. Amps is couloumbs per second (Q/t), if you multiply by time again you get (Qt/t) which is just Q, or charge.
Snow in the air is probably a bigger problem than snow on the ground, blizzards with 20m or less visibility aren't that uncommon far north, really easy to get lost and die during those since the snow also blots out the terrain unlike fog.

Atlassian to Buy Loom for $975M in Bet on Remote Work
They had outstanding product-market fit. The _only_ problem is that the market of people who have juice bags and do not know how to open them (I.e. two year olds) do not make purchasing decisions.
This is maybe getting tangential but one of my pet peeves is that the industry doesn't establish standards for large batteries, like lawnmowers and leafblowers. If they were serious about electric transition they would make batteries transferable like AA, AAA batteries etc.

I understand the issues involved and that there are nontrivial obstacles (see: IoT), but it is really frustrating to deal with manufacturer lock-in. I also think it adds to confusion of the sort in the linked piece because there isn't a discussion of standards per se along the lines you're mentioning.

I suppose safety issues are magnified a hundredfold compared to the problems that people have run into with USB product standard mismatch but that's probably another reason why people might actually buy brand-name OEM batteries even if there were standards.

I guess in general I wish there was some open industry discussion of this, even if it meant a white paper where they throw up their hands and decide it's too risky.

In a saner world, it would be implicit in the USB-C. As it is, you know that it supports 5V.

It might also support higher voltages (up to 20V), though if it doesn't specify I wouldn't assume. If you need higher voltage, you'll have to look for a battery that specifies it. (And hope that the package isn't lying.)

Don't quote capacity. It is the correct tern, physically. Capacity is the amount of electrical charge something can store, Ah is unit of that. Not the natural unit though, that would be Coulomb (C).

Why use Charge and not energy? Because the voltage changes as the battery is discharging, so it's not as straight forward as just multiplying with the voltage.

Metric seconds are quite close to regular seconds since there are 100,000 metric seconds in a full day compared to 86400 regular seconds.

Which means that 40 metric seconds is about 46.3 regular seconds - I.E. something is wrong with the charts on this website.

It also means a metric minute which is 100 seconds would be 115.7 regular seconds so a bit less than two minutes, not 2.4 minutes as claimed.
I doubt any 3rd party will go far, but they do help. When the green or libertarian party starts to gain votes, the democrat or republican party changes their policy to include concepts that the respective party had.

Kine (https://github.com/k3s-io/kine) is a shim or an external process (when not k3s) that translates the etcd api to enable compatibility with a database or alternative data store.
Kubernetes natively talks etcd, so this translation is what enables its usage with sqlite or another database, but it incurs an overhead.

I don't have specific numbers unfortunately since it was years ago I benchmarked Kine against etcd. But I had a better results with etcd both in cluster and single node.

I gave you an upvote bc I mostly agree, but as a counterpoint...

Atlassian is a big company that is successful at what they do, bigger than Loom and presumably with more resources. So I am confident they could have just copied Loom's business model and maybe even implemented better to fit their needs, since they have staff in place. It would certainly involve staffing up where needed, but I think they could have pulled it off and saved money. Also, with an acquisition, now they ave to integrate Loom into the broader Atlassian org, which wont be trivial.

So there are legit trade-offs with an acquisition.

That being said, spending $1B on a acquisition also saves time.

> How many of those devices actually had 5V batteries inside? (Are there even credible 5V Li-poly battery banks)?

That’s a good point and revealed that I conflated battery capacity with source-able/usable power. You are correct (as far as I am aware as well) that you cannot use a lithium ion/polymer based battery chemistry and have between 4.75 and 5.25 volts output.

Thinking about it some more, the battery packs seem to represent a special case where the function of the device is to provide power and, as per your point about squeezing out maximum power, we probably need to have two separate power ratings: one for the battery and one for the usable output.
Definitely looks like it. There's also no source on the images, and each image has a different-looking spacecraft.

getting into the infantry, at least in the US military, is non-trivial. entire generations have now grown up on Halo and Modern Warfare 2, and there are no shortages of wanna be trigger pullers. Meanwhile something like 1 in 11 troopers in the Army are combat arms -- you need a lot of logistics, mechanical, etc. bodies. Closer to 1 in 7 in the Marines, but still the majority aren't combat arms.

might be a different story in UKR, where they're grinding through troops and everyone is looking to be in the rear w/ the gear.

but that selection bias is definitely geared towards motivated combat troopers. meanwhile some kid from Missouri joins up thinking he's gonna get out of his shit town and learn computers or something but then spends 18 hours a day filtering water and fuel at a remote base in Germany for 4 years.

In the consumer space, virtually no battery I've seen in more than a decade is less than 1000mAh. If you looked at the Reddit post, you know we're talking about laptops, tablets, phones, external power banks, that type of consumer-facing application. But, even then, converting is fine. People understand there are 1000 meters in a kilometer. I don't think any of this is rocket science.

However, outside of the consumer space... doing conversions like that is also fine. When browsing DigiKey, components are often listed in the optimal unit prefix. When necessary (not so much with batteries), the interface allows you to filter based on ranges you provide, and it will perform the necessary conversions for all the products to give you an accurate list.

LiPo batteries vary a lot from voltage but all look the same and have the same connectors.

These batteries are used a lot in RC cars, drones, etc. Basically anything you want to power where regular batteries wont do the job.
Data sheets are a thing. More data doesn't help though, unless the consumer knows what it means. Also, it isn't really even that simple, battery capacity can vary depending on discharge rates. The root of the problem is that batteries are complicated and most people aren't engineers.

Since you have to specify the voltage no matter how you measure energy, because voltage is what primarily determines if a battery will work in most consumer electronics, what units you specify energy in is not relevant as far as consumers comparing batteries go.

If I see that two batteries have the same stated voltage and battery A has higher mAh than B I know that A should last longer in my device.

But that's exactly the same if I see A and B have the same voltage but A has higher mWh. It should last longer.

Even if the energy was specified in some completely ridiculous way such as how much mass that amount of energy could lift a 2 liter bottle of diet Pepsi on the moon I'd just have to look at the two numbers and pick the bigger one.

The republican majority during the first two years of his presidency stalled on enacting any of his policy- and now they are much more vocally opposed to Trump- as if they always hadn't been. He's a populist candidate- but he's not at all popular with the actual politicians, who are currently the actual infrastructure of the party. His hold on the party is tenuous at best- mostly because the people that oppose him when it comes to voting will still happily campaign with him and win based on his supporters. The recent soft blacklisting of Trump support from Fox is also going to take out a chunk of his base that will continue to vote for the color red.

That's no excuse for the hedge funds, of course.
Not to disagree, but that’s what they were using.
> which is more difficult to scale up effectively than voltage

For those who don't know, this is because losses scale as current squared, instead of just proportionally like it does with voltage.

For example, charging a power bank with 20W of power at 5V you need to supply 4A of current. If you have a good USB cable with 0.1 Ohm resistance, that results in P = V*I = (I*R)*I = (4*0.1) * 4 = 1.6W of loss in the cable[1].

If instead you could use 20V to charge, then the current would only need to be 1A and hence the loss just (1*0.1) * 1 = 0.1W.
