“Then there is the % address operator: user %domainB@domainA is first sent to domainA, which expands the rightmost (in this case, the only) percent sign to an @ sign. The address is now user@domainB, and the mailer happily forwards your message to domainB, which delivers it to user. This type of address is sometimes referred to as “Ye Olde ARPAnet Kludge,” and its use is discouraged“

Please don’t terrify your contractors. They fix your place, and you want them on your side doing a good job.

Personally, I’d start with divide and conquer. If you’re working on a relevant code base chances are that you can’t learn all the API spec and documentation because it’s just too much.

Correcting the correction:

> When you connect 2 9000 mAh cells in series, the resulting battery has 2x the voltage but the same mAh capacity. In parallel, the battery has the same voltage but 2x the mAh.

The relevant units are:

* Capacity (Q, in mAh, Ah, kWh, etc)

* Power (P, in Watts)

* Voltage (U, in Volts)

* Current (I, in Amperes)

* Duration (t, in mostly measured in hours)

And the relevant formulas are:

* P = U x I or Power equals Voltage(difference) times Current

* Q = P x t or Capacity equals Power times duration

From this we can establish that connecting batteries in series or in parallel will not change their Capacity. When having 13 batteries of 29000mAh, or 29Ah, you have 13 x 29 = 377Ah or 377000mAh. Connecting batteries in series or parallel does make a difference in voltage and current: a string in series will increase the voltage while keeping the current the same (theoretically, in practice you get less than the current of the weakest cell); a parallel setup will increase the maximum current while keeping the voltage the same (again, in theory).

Same for me. I wanted to contribute, but the amount of dependencies needed to get a local build to run was a major hurdle.

Except that the argument here was about bass, and the paper shows that age dependent hearing frequency response varies mostly in the mid-high range.

Not saying you are wrong, but this is anecdotal. I’d rather try to interpret crash statistics than use my own experience.

All of this. Plus the exhaust gasses and tire wear pollutants causing early deaths. The noise (bigger) cars make disrupting quiet places like parks and porches, balconies, bedrooms causing stress. The waste of used cars, often being transported to third world countries. Cars kill in so many ways, especially big cars.

The counterpoint to that article is: US Big Tech could also abide to EU laws and avoid fines altogether.

New comment by berikv in "Bug squash: An underrated interview question"

berikv — Tue, 20 Aug 2024 21:46:45 +0000

Although I like this interview question, it has a big downside. You make the candidate spend quite a lot of effort while you as an interviewer don’t learn much. The answer to “Can this candidate find and fix this bug?” is not necessarily equal to “Is this candidate a good expansion of the team. What do they bring that we need?”

With AI closing in on general intelligence, using just binary numbers and some calculations, I’m going to place my bet that quantum entanglement is not necessarily for general intelligence.

New comment by berikv in "Apple leaker Kuo: Apple plans to replace the iPhone with AR in 10 years"

berikv — Fri, 26 Nov 2021 16:11:41 +0000

It was eight years ago when Google delivered the gadget-man’s wet dream: The Google Glass. My company at the time had a pair so we could try them. It was immediately clear that glasses aren’t the same product as smartphones. The first Google glass UX was very poor. And even if newer “glass” products can solve some issues, they will never fully replace a touch screen. Arguing that phones will be replaced by glasses, to me, sounds like arguing you’re going to do your office work using Alexa. It just doesn’t make sense.

> "So you plant your saplings and then you have to maintain the forest for 100 years. That's multiple generations of people. How many companies last 100 years these days? How on earth is anyone going to afford to maintain that forest, hiring the team of people you need to do that? It doesn't make any sense."

Forests don’t make any sense, who’s willing to pay for them anyway?

Could this be even more capitalist propaganda?

Also, the EU government is not hugely popular in the public opinion. Years ago the EU government was popularly known for creating nonsensical rules (and there are indeed examples of nonsensical rules).

To claim their future existence, the EU government really has to prove their usefulness for the EU citizens.
