Comment Re:Chrome (Score 3, Informative) 130

Maybe a better way to put it is to think of three ranges: At low enough power, a coating isn't needed. At high enough power, any practical coating will be burned through. The in-between range where a reflective coating can make a difference is surprising narrow, not much more than a factor of 10 in power, because really good wide-spectrum reflectivities will be less than 99%.

The best reflectivity is fragile. A 10 W laser can burn a crater in a beautiful lab-grade mirror. (Flaw in the coating? minuscule deterioration? speck of dust?)

This can be translated into time instead. So if the laser damages the target in a microsecond, no coating will help. But if the beam has to be held on target for tens of seconds, some reflectivity will turn this into minutes and may make a difference.

Comment Javascript (Score 4, Informative) 226

he answer seems to be Javascript. When I have NoScript blocking everything, then browser load is minimal and stays minimal indefinitely regardless of the number of tabs. Certain sites that require Javascript must periodically have their tabs killed and then reloaded to keep the CPU usage reasonable.

Maybe what we need is Javascript sandboxing that can pause scripts in tabs without focus, limit CPU usage, autokill pages, and so on. I have no idea whether the engine is buggy or the site code is buggy or the frameworks are broken or whatever, but if it hasn't been fixed yet, then we need a drastic solution.

And if X on Wayland works as well as XQuartz, it is just barely better than useless. When I run remote programs on XQuartz, it crashes a lot. Some programs can't reasonably be used at all, because XQuartz crashes so often (accidently hitting the mouse scroll wheel while in emacs seems to cause a crash every time). Real X on Linux has always worked beautifully in comparison. If X on Wayland is only as good as XQuartz, it is worth having in an emergency but no good for daily work. YMMV.

Well, yes, all of these to various extents. Plus the need at times to be precise, when the equivalent in general language is vague. Plus when writing for your peers, it is a lot easier to use your shared language.

Any particular impenetrable paper may result from one of these causes or any combination.

It is fair to say that if an informed layperson (someone with an ongoing interest in the field, not a specialized degree) cannot get the gist of the argument, then the paper is poorly written and shouldn't have been published.

Comment Re:If text is enough... (Score 1) 227

... then just use a simple text file. Come up with your own scheme for title, date and time and it will work. Either as single file with search, or with multiple files and grep(1).

And please make things easier on yourself by setting up commands to automate your own chosen format. I have simple commands for opening a file with today's date in the name, inserting date and time into the text of the file, generating numbered lines, and so on.

Autogenerating dates and times is particularly valuable in avoiding extremely costly mistakes.

(For me, this is aliasing "mylog" to something like emacs ~/Notes/`date +"%Y%m%d"`.txt)

How can you point out that it is only MJG's work that lets Linux be more popular on new hardware than, oh, BeOS? That goes completely against the agreed-on narrative so ably established by previous posters, that Garrett is a useless whiner and who needs him. This is why it is so important to read everything before adding your own 2 cents.

When they were called on their fraud, they checked their research and confirmed they did find an thermal anomaly as predicted by Pons and Fleischmann.

Oh, you've been listening to Eugene Mallove. (Just checked Wikipedia and heard for the first time of his terrible murder, so I will limit what I say.)

Scientific laboratories are complicated places. If the people who were there say, "There is a blip in the data when we changed the settings on the something-or-other" and someone who wasn't there says "This published plot PROVES cold fusion occurred" the default should not be to believe the person who wasn't there.

The experiment is not proof that there is no cold fusion. It is proof that cold fusion is not a robust, easily obtainable effect that could be reproduced based on the information publicly available at the time.

Comment Re:Hmmm .... (Score 1) 186

For example, it was shown almost TWENTY YEARS AGO in Jet that the capabilities of modern experiments outstripped their ability to deal with the effects of the resulting radiation, and no one has run a large experiment using a reactor-like fuel mix since.

Since then, there has been quite a bit of evidence collected that trying to design and construct a new machine with reactor-grade shielding on a shoestring budget is not something that can be accomplished quickly.

Comment Re:Work = Achieves Goals (Score 1) 337

No, the goal of every "reactor" ever built so far is to study plasma physics. To make the site ready for megawatts of flux of neutrons and gammas would cost five times as much and take 5 times as long to build. It's like testing water pumps and cooling towers for a fission plant without any uranium around--it's faster, cheaper, and safer. One device is under construction that WILL generate more power than it takes in, and the costs and building times are much higher in consequence.
