Comment Re:No such thing as dark energy (Score 1) 67

The summary has not one but two examples of groups critically studying dark energy.

Yes, but they still are starting from the hypothesis that there IS dark energy and it has been accerating expansion. From TFA: "This adjustment showed that not only had dark energy changed over time...". I.e. they are trying to FIX dark energy calculations with adjustments.

Read my original post. In very similar way, the science tried to fix geocentric model with epicycles end deferents, resulting in REALLY odd orbits. And somehow those still seemed to fit observations. It required a more radical shift to heliocentric model to "beautify" the physics again back to simple formulas, not needing layers of adjustments. https://en.wikipedia.org/wiki/...

Like physicists are not trying to provide evidence for or disprove the dark energy model.

Actually, no, they are not. Meaning that dark energy is now mainstream physics, and if you dare to think otherwise, you are sidelined - very difficult to get funding for studies, or publications in peer reviewed journals. Hence, the only ones trying to prove otherwise are considered crackpots.

One plausible theory is that dark energy is simply not constant, the constant value is an assumption, but only that.

Again, epicycles.... Instead of trying to create a mathematical model for dark energy, one can explain the supernova observations themselves with e.g. variable light speed theory (i.e. in the past light travelled slower/faster). Cannot be easily tested or proven, but throwing away the assumption that light speed is constant over time, it is easy to come up with theories, in which dark energy is not needed.

But regarding light speed, we have now dug ourselvers into a hole by defining even time itself (one second) using c (time it takes for light to travel 299792458 meters). So, from now on, by definition, light speed IS FORCED to be constant (if the speed actually changes, it is the time (one second) that is flowing faster/slower.

Dark energy, to my understanding, is the fruit of supernova observations, which seems to show expanding universe, which would then require dark energy. It is deferents and epicycles once again - more and more complex mathematical models needed to explain a false hypothesis, as new observations surface.

I hope alternative models of explaining the supernova measurements would get more attention, so that some day we could admit that this geocentric..., sorry, this dark energy model was wrong after all.

Comment Re:I still write about 15 checks a year... (Score 1) 144

We haven't even eliminated magstrips. We still have them around for backup. An attacker can disable a chip reader by making a special card that applies epoxy to the contacts when it's inserted, which you can do with e.g. a dremel, forcing subsequent users to fall back to the strip.

Theoretical scenario, no? Going that route, the attacker can fill the whole damn card slot with epoxy, and no card, be it magnetic stripe or chip, can be inserted at all.

WTF... Here (Finland), I've been living my adult life for more than 30 years now. And I have NEVER written a check in my life. Electronic banking (direct deposit you call it there?) since last millennia now. And as for the taxes, the same thing. Actually local "IRS" is quite advanced, for years, there has been no need to "file" anything tax related. All information has already been gathered, I'll just get a copy of the calculation that I can verify on their website. Postal money order? WTF again...

What do you do for entertainment then? Hoop on a stick?

For entertainment? Maybe a live gig, occasionally a Netflix movie (no series). For pastime, running, orienteering, swimming, forestry (lumberjack thing), hiking, whatever. Outdoors mostly.

Do you consume other media the same way? If you want to watch a TV show about doctors you just search Netflix for "doctor show"? If you want a jazz song you search itunes for "jazz song"?

Seems like an inefficient way, but I guess your "life" is very busy!

You confuse information search with entertainment. Like I said, I have a life outside digital world, wouldn't waste it on some "entertainment content" from Youtube. So yes, it is much more efficient to search for "how to fix a bootloader" video than to subscribe to a Windows tips and tricks channel and wait, if such a video pops up.

How do you find content? External sites? Whatever Youtube is recommending everyone?

I know what I want to watch, so I go and search for it!

Youtube is quite handy in providing all kinds of guidance, e.g. lately how to replace a capacitor in my receiver, how to fell a tree, or how to get grub back, when windows took over the boot process. That doesn't mean I would have any desire to subscribe to an electronics, lumberjack or windows tips channel.

I have a life, I do not need random "content" to fill it with.

The only Windows application I use heavily on Windows 7 but cannot get for Linux is "Everything". It's an amazing app, but tied to the implementation of NTFS.

What are you using on Linux for file search? Have you tried FSearch, how does it compare to Everything? https://cboxdoerfer.github.io/...

Comment Re:For the love of $DEITY, why not a heat pump? (Score 1) 90

For the love of $DEITY, why not just use a heat pump? It takes a fraction of the energy cost to move the heat, compared to generating it. If it is too cold, then by all means, use another heat source, but save the electrical heat for the actual cold weather.

Exactly. And it is seldom too cold for a heat pump, if you buy a modern one. I have Toshiba Premium+ 25 bought a couple of years ago. It gives COP 2 in -30C (-22F). Costs around $2000, installed, here in Finland.

Should be fairly simple Russia did offer a workaround, after all: Use two sim cards, don't permit the Russian one to contact towers outside of Russia. Fly it from outside using the other SIM.

Even easier is to use the other workaround given by russia, Use a warehouse near the border to manually connect sim cards to the russian network for a while, then move them to be used in the next batch of drones to be launched (if launched further away, activate the mobile connection only after the drone has reached russian network).

This is really well established. False positives make any detection system unusable.

I'll just give a counterexample, which invalidates your point. We have Fire detectors in our house, every room has one in the ceiling. Once in a while, a detector goes off to some random reason, typically cooking (with lots of steam generated). So no fire. False positive. Does it make the detection system unusable? Do you feel that I should rip out those detectors?
