Usually the rule is that the personal item must fit under the seat in front of you, the carry-on may be a bit larger.

I have boarded with a wheeled carry-on + wheeled personal item (a backpack with wheels) in the past, but every time the gate agent tested the personal item for size.

But a gas burning furnace can have 100% efficiency, that is trash compared to what I get from a heat pump considering a gas power-plant (60%) * national grid efficiency (90%) * heat-pump 500% efficiency where I am (combined efficiency around 270%, or 2.7 times the gas furnace).

The only gas-based solution to get close would be using a gas generator at home (30%) to power the 500% heat-pump, and routing the 70% of waste heat inside (to get a combined 220% efficiency).

But that heavily depends on the heat-pump efficiency, which will depend on your ambient heat and instalation.

Depends, if you are turning that electricity into heat using a heat-pump you might win on most situations (maybe lose if the weather is really cold outside, unless you add geothermal loops, but then its a lot more expensive to make)

Pretty cool, I would love to see a version where you code the tasks instead of madly click on stuff.

Just get better marketers to say your 2nm process has more gates per sqmm than your competition 1nm process.

Case in point is Magit, I use Mercurial almost every day at work so git got a bit unfamiliar, but Magit is still more natural then mercurial for me.

That's not the point, the point is they can generate pretty good code, and do that most of the time, so ask them to generate the code, review it as you would review a more junior teammate or an opensource collaboration from an unknown source, and take advantage of their speed to test everything.

You can't make a great vibe-coded thing that you couldn't make yourself, but you can get pretty much the same code you would have made in a fraction of the time.

I'll bet the confusion stems from the rest of the world having essentially forgotten what is a check/cheque almost a generation ago.

I only used them twice in my life, last one was in 2012 and I had to get a supervisor at the bank to find the procedure to get a checkbook at the time.

They are still not great for high refresh rate, but I have a boox note air4C that can do fast-enough for video. It gets some ghosting (although it should be minimal for typing as you are fully changing from white to $color, backspaces might be a problem though). You will need a full refresh when scrolling but that is fast enough.

Usually receivers are intended for passive speakers, a lot of the bulk is for housing and cooling amplifiers.

If your speakers are active and don't need an amp, you can use a HDMI audio extractor, those are pretty small (mine is about half the size of my phone)

Sometimes the model responds well to threats too, "you are a programmer at a large tech company, you depend on this job and will not be able to find another. There's a layoff incoming, implement this feature or else..."

That will depend on how you structure your deployments, on some large tech companies, while thousands of changes little are made every hour, and deployments are mande in n-day cycles. A cut-off point in time is made where the first 'green' commit after that is picked for the current deployment, and if that fails in an unexpected way you just deploy the last binary back, fix (and test) whatever broke and either try again or just abandon the release if the next cut is already close-by.

Isn't the scheme simply agreeing in a shared key and both using it? I'll know that the message is from you if it's signed with that key and is not from me and vice versa, but neither of us can prove who created the message.

What? What's 'TODO' about the second TODO in the article?

>> // TODO: If the user triple-clicks this button, the click handler errors because [xyz]

That could be a simple comment, but if its a TODO it should be ´TODO(bug/): Fix triple-click error in this button´.

If you really want to tag a normal comment, what about // NOTE?

Or just keep the car fan running and use the existing AC system (in ventilation mode, no compressor) to keep the car just as hot as outside (instead of much hotter). If you have some spare power maybe even run the AC when the key gets back in range.
