axiolite··on Google Ad Disguising Itself as www.gimp.org
> it'd be trivial for a bad actor to change them if the files are compromised.

But it's trivial for responsible members of an organization to set-up a continuous, automated verification of the checksums listed on a web page. It wouldn't be practical to do that with the ISOs, directly.

Of course if the organization is lazy or incompetent, and chooses not to do so, then they have only themselves to blame. But if you fail to compare your downloaded files to the listed checksums, that's all on you.

I fail to see how verifying decades-old degrees would have prevented this.

axiolite··on Why are there so few dead bugs on windshields these days?
> another cause of decline is our over obsession with landscaping and municipal lights

Very much unlike their incandescent and florescent predecessors, LED lights emit practically no ultraviolet wavelengths, and therefore have a drastically reduced attractive effect on insects. Whatever effect outdoor lighting may have on insects, should be showing precipitous declines over the past several years, as LEDs have become the dominant artificial light source.

axiolite··on Space-based solar power is getting serious
> Unfortunately, many of these frequencies are used by our tech.

So what? Microwave frequencies aren't entirely line-of-sight, but they aren't going to diffuse very far off-target. Unless you have houses in between elements of the receiving antenna array, the disruption of comms in the immediate area isn't going to actually affect anybody. Perhaps there's some risk to jets that choose to fly through the energy beam.

axiolite··on FBI Raids Star ABC News Producer’s Home
Seems like Tatiana thought there was an earth shattering story here, then turned up nothing. Had to make something of all the time wasted, so turned it into a shaggy dog story.

Who cares that neighbors in the apartment building and co-workers are wondering what happened to Meek? I don't notify my neighbors when I leave, or check-in with former employers after quitting.

Sounds like his lawyer is still in contact with Meek:

“Mr. Meek is unaware of what allegations anonymous sources are making about his possession of classified documents,” his lawyer, Eugene Gorokhov, said in a statement.

And he's the one complaining about details getting out:

“It is highly inappropriate, and illegal, for individuals in the government to leak information about an ongoing investigation. We hope that the DOJ [Department of Justice] promptly investigates the source of this leak.”

...so apparently Meek doesn't want any publicity around this incident.

A place to live is a rather inelastic commodity. If the price goes up across the board, people will pay, until they can't possibly afford the going rent and are driven into homelessness.

axiolite··on Oracle lays off more than 200 California-based workers
> Their RDBMS is an amazing product.

I hope you're referring to MySQL!

The Oracle DB is a crufty old throwback to the bad old days where you needed highly specialized experts to spend dozens of hours to install, configure, and tune a massively admin unfriendly piece of software.

It comes with a command-line tool (psql) with NO command history, NO tab completion, or other interactive help system. Only uncompressed file import/export formats. The need to manually manage data files when creating a table, and even specifying their file sizes. Oracle's DB is quite stable and reliable, but it is practically a biplane or steam locomotive compared to almost any other DB out there. Even the similarly aged PostgreSQL is an absolute joy to work with in comparison.

axiolite··on California man fined for selling maps of property boundaries without a license
> Forcing that issue to a head would hopefully result in a more functional system in the end.

Perhaps it would... but only after we finish with the cleanup from the inevitable civil war.

Forcing controversial issues to come to a head very often ends badly. Compromise is more likely to lead to stability.

axiolite··on California man fined for selling maps of property boundaries without a license
Sounds nice in theory, but after decades of everything running smoothly, people forget just how instrumental certain laws were to ensure that stability.

It's a lot like anti-vaxers, anti-pasteurization, and other anti-science fads. And I can point to the repeal of banking regs like Glass-Steagall which resulted in the ~2007 financial crisis and recession. Including a post-it note on a law isn't going to give future people the same perspective as someone who lived through the issues first-hand. If that worked, we wouldn't have voters repeatedly supporting politicians who make the same insane promises that never work.

> Edit: I see downvotes. But no one can answer the question.. .

You likely would have had fewer downvotes if you had just answered in earnest the question asked: "Are you asking a question or being dismissive and flippant?" Then maybe you would have gotten an answer or two.

Instead, choosing to reply with inflammatory language like "you couldn’t truthfully answer the question" seem to indicate you are probably not interested in any ration discussion, but are instead going to dig in and dismiss or attack anyone who disagrees with you. Certainly doesn't make me want to spend any time explaining the bleeding obvious to you, but perhaps someone else will.

AMD CPUs were vulnerable to fewer of the speculative execution bugs than Intel, and the performance impact of the mitigations on AMD CPUs were far less than Intel.

The Doomsday Clock is just a pointless publicity stunt. 1440 minutes on a clock, and yet it has never been more than 17 minutes from midnight.

It was farther from midnight in 1962 during the Cuban Missile Crisis than in 2007.

axiolite··on New system retrofits diesel engines to run on 90% hydrogen
> you are also admitting that hydrogen fuel cells are just as efficient.

You've pulled that delusion out of thin air. Fuel cells aren't batteries. Li-Ion gets ~90% conversion efficiency while fuel cells may get ~60%.

And with hydrogen that's only if you use it right after you've generated it. As soon as you need to compress and transport it, you're losing a lot more. Batteries charge from the grid, which itself has single-digit percentage losses. Hydrogen fuel cells can't do that, they have tremendous inefficiencies as the Department of Energy quote already stated.

Hydrogen fuel cells are far more expensive and vastly less efficient than batteries. There's absolutely no reason to continue to push the former when the latter is immensely practical and available today.

But you seem to ignore all information that doesn't bode well for your hydrogen dream, so I expect you'll find yet another reason to disregard this as well.

Farewell.

> There is no possibility of commercial quantities of lithium being extracted from seawater.

Lithium seawater extraction is much more likely than a green hydrogen economy! In practice, it gets more practical as you couple lithium extraction with other processes, like desalination. In fact, if you manage to get hydrogen production from seawater going, extracting Lithium from the byproducts will be quite economical.

> You have swallowed myths and fantasies of your own.

I pointed it out only as a response to your equally absurd statement that hydrogen fuel is "fully renewable and in abundance". Clearly, Lithium fits just as well.

> you are unwittingly admitting that hydrogen fuel cells are a viable technology for transportation purposes.

Certainly not. Fuel cells could certainly become practical for transportation, but HYDROGEN is not, with or without use in a fuel cell, and that's true for the several reasons I've already very clearly outlined.

I suggest you get over yourself. I am indeed a video expert with decades of IVTC experience.

The first line of your reply was:

"but rarely does anyone actually do this"

That is factually incorrect, no matter how many years of experience you may have.

axiolite··on Ugliest Airplane Ever Built Predicted the Future
> better twin engine planes totally obviating a lot of hub-to-hub travel.

Yeah, but that was entirely predictable...

There were twin-engine jets from both Boeing and Airbus flying trans-Atlantic, the 737 was a very popular aircraft, and the ETOPS rules went into effect in 1985, years before the very first steps in A380 development. The future direction of air travel was out there for any well-informed individuals in the industry to see.

> was there some reason not to just pull the laptop batteries and use normal remote-controllable outlets?

What happens when someone accidentally does a clean shutdown from within the OS?

Switchable PDUs have the same issue. You need something like Wake-on-LAN in addition to the switchable power to ensure you don't need to do a late night drive into the data center or office.

axiolite··on Why 23.976 and not 24 FPS? (2016)
> Why not 60 fps considering it's the standard refresh rate of practically all displays that are in use?

Actually, I'd say 50fields/sec is the most popular frame-rate in-use around the world. Theatres still use 24fps or perhaps 48fps.

Shooting at 1200fps would make everybody happy. But 24fps works pretty well.

axiolite··on Why 23.976 and not 24 FPS? (2016)
It's not actually 23.976fps. That's just the friendly, rounded notation we all use in discussion.

It's actually 24000/1001, or in integers: 23.976023976023976... fps.

axiolite··on Why 23.976 and not 24 FPS? (2016)
Parent was obvious talking about converting 25fps PAL video to 30fs NTSC frame rate, which happens ALL THE TIME...

NOT about converting from film to PAL. You are arguing with no-one.

> Battery has very similar issues with the rare earth problems

Utterly false. The elements needed for Li-Ion batteries are very much "in abundance" on Earth. Elements like lithium can be extracted from seawater around the world in quantities far in excess of what humans will ever use. It's just a little less economical than current sources.

Which gets us right back to hydrogen! There's no limit on the amount of hydrogen you can make, but YOU CAN'T MAKE IT ECONOMICALLY. Dismissing eminently practical, extremely efficient battery electric vehicles in favor of an insanely impractical, uneconomical, and thoroughly insane hydrogen economy that is going to vastly increase greenhouse gas emissions in the near future is utterly absurd.

> but its also no good for things like big aircraft.

Neither is hydrogen! Not a snowball's chance in hell of a hydrogen 737 or A320. The fuel tanks would need to be vastly too large and too heavy.

Li-Ion is practical for small, short-hop aircraft TODAY. Short-hop aircraft could gradually reduce the need for larger aircraft (e.g. two short hops instead of one non-stop flight), etc.

And there is absolutely potential for battery electric large aircraft in the not-too-distant future. Lower speed, propeller based flight increases efficiency. Flying wing aircraft designs can reduce power consumption by about 1/3rd. And finally, high power battery chemistries like lithium-air[1] actual have the same energy density as gasoline, BUT batteries/motors get ~90% conversion efficiency instead of the measly ~40% conversion efficiency of current turbofans!

axiolite··on New system retrofits diesel engines to run on 90% hydrogen
No it is not. Hydrogen is laughable, absurdly inefficient as an energy storage method:

"Due to its relatively low volumetric energy density, transportation, storage and final delivery to the point of use can be one of the significant costs and energy inefficiencies associated with using hydrogen as an energy carrier." https://www.hydrogen.energy.gov/delivery.html

"Natural gas stored at 20.78 MPa (3000 psig) and 21.1°C (70°F) contains five times as much energy as hydrogen stored under the same conditions." https://www.sciencedirect.com/science/article/abs/pii/036031...

Battery electric vehicles, by comparison, are vastly more efficient.
