Tips & Notices – April 2019

About “Tips”:

While I’m mostly interested in things having to do with:

Computer stuff, especially small single board computers
Making money, usually via trading
Weather and climate (“Global Warming” & “Climate Change”)
Quakes, Volcanoes, and other Earth Sciences
Current economic and political events
(often as those last three have impact on money and climate things…)
And just about any ‘way cool’ interesting science or technology
Oh, and lately, cars &
numerical computing / graphing with languages like Python & Julia ;-)

If something else is interesting to you, put a “tip” here as you like.

If there is a current Hot Topic for active discussion, try one of the Weekly Occasional Open Discussion pages here:

You can also look at the list of “Categories” on the right hand side and get an idea of any other broad area of interest.

This ought not to be seen as a “limit” on what is “interesting”, more as a “focus list” with other things that are interesting being fair game as well.

The History:

Note that “pages” are the things reached from links on the top bar just under the pretty picture. “Postings” are reached from the listing along the right side of any given article (posting).

Since WordPress has decided that comments on Pages, like the Old Tips Pages, won’t show up in recent comments, it kind of breaks the value of it for me. In response, I shifted from a set of “pages” to a set of “postings”. As any given Tips Posting gets full, I’ll add a new one.

I have kept the same general format, with the T page (top bar) still pointing to both the archive of Tips Pages as well as the series of new Postings via a link to the TIPS category.

This is the next posting from prior Tips postings. Same idea, just a new set of space to put pointers to things of interest. The most immediately preceding Tips posting is:

The generic “T” parent page remains up top, where older copies of the various “Tips” pages can be found archived. The Tips category (see list at right) marks Tips postings for easy location.

    So, science is NOT settled. Scientists claim that under certain conditions, light travels faster than, er, uhm … well, light.

    “Abouraddy and study co-author Esat Kondakci demonstrated they could speed a pulse of light up to 30 times the speed of light, slow it down to half the speed of light, and also make the pulse travel backward. … ‘We’re able to control the speed of the pulse by going into the pulse itself and reorganizing its energy such that its space and time degrees of freedom are mixed in with each other,’ Abouraddy said.”

    This is so weird I can’t even figure out what it means.

  2. E.M.Smith says:

    I think they are saying they’ve got a trick that lets you swap space for time… which if true starts to make all sorts of exotic Sci Fi a possible…. Can you say “static warp field” Scotty?

    @Pouncer reminds me of Heinlein’s book The Fifth Column…

    Digging into it… it isn’t the LIGHT that moves FTL but the focal point…

    A “flying focus” combines a lens that focuses specific colors of light at different locations with the recent Nobel Prize winning chirped-pulse amplification technology, which organizes the colors of light in time. Imagine a laser producing a continuously changing rainbow of colors that start with blue and end with red. Now focus the light with a lens that concentrates the red light close to the lens and blue light much farther from the lens. Because of the time delay between the colors, the high-intensity focal point moves. By changing the time delay separating the different colors, this spot can be made to move at any speed.

    “The flying focus turns out to be super powerful,” said Dustin Froula, the Plasma Physics Group Leader at the University of Rochester’s Laboratory for Laser Energetics. “It allows us to generate high intensities over hundreds of times the distance than we could before and at any speed. We’re now trying to make the next generation of high-powered lasers and flying focus could be that enabling technology.” His team, supported by the Department of Energy Office of Fusion Energy Sciences, will be presenting this research at the upcoming American Physical Society’s Division of Plasma Physics meeting in Portland, Ore.

    “Our group set out to design an experiment that would measure the propagation of a focal spot at any velocity, including 50 times the speed of light. This required a new diagnostic that could make a movie with frames separated by a trillionth of a second,” Froula said.

    So, OK, that’s a nice trick but it isn’t light going “at any speed” it is the spot where the focus lands that is being moved – a non-physical thing.

    There’s a nitrogen laser uses a similar trick. Take a metal plate and cut a groove in the middle. Fill it with nitrogen. Dump a pulse of electrons into one corner. They spread out at the speed of light (more or less) in a circle BUT the arrival of that circle at the groove with the nitrogen channel propagates along the channel at FTL because it isn’t a physical thing but the mathematical property of the arrival time of the light speed circle at a line.

    This it turns out is a feature as the gas at the arrival point at one end begins to emit photons from the electrical stress. Some travel down the column of gas and arrive at the next spot just AFTER the charge made it ready to emit light, so you get Light Amplification By Stimulated Emission of Radiation as the first photons pick up some friends. Continue to the other end of the channel where a “broom stick sized chunk of light” flies out the end. No mirrors needed…

    At no time does any THING travel FTL, but an effect propagates FTL.

    Looking for that asserted full wikileaks drop, I ran into this, that claims to be Hillary’s emails:

    What odds that Wikileaks has the “really, really good bits” as insurance?

  8. H.R. says:

    @Another Ian – I was under the impression that this release was the insurance policy. But now that you bring it up, he may have saved the most damning MOAR (Mother Of All Releases) as a get-out-of-jail-free card in the event someone entertains the idea of silencing him… permanently.

    I would think he is still holding a “If I’m going down, you are all going down” file with a dead man’s switch.

  9. E.M.Smith says:

    The insurance files are encrypted. The “juicy bits” are already out there so propagation can’t be blocked during a “take down” or as now, an arrest. The “deadman switch” is on release of the decryption key….The way I’d do that is a $10 / year almost no use “cloud” VM (likely several in different countries) that wakes up once a year and listens for me. IF I reply, it goes back to sleep. If no reply inside, say, a month, then it posts the decryption key to dozens of sites, boards, and emails it to “a cast of thousands”…

    Further, I’d add a layer of backup sites that I NEVER connect with. They would look for the primaries to still be up and alive. IFF the primaries are down, they launch the key release. In this way watching my traffic can’t let you find the deadman switch sites (not that knowing one was in Russia and another in China and a third in Iran would help the USA… ;-) This layer would connect through TOR and VPN to double mask IP of origin… (as would I, when doing my check in once / year… from a dedicated tablet used for NOTHING else from a public WiFi hot spot…)

    I’d likely also have a “trusted person” who could release it if all tech methods failed.

  10. Larry Ledwick says:

    Personally I suspect that the book he was clutching as he was arrested by Gore Vidal was a signal to his supporters, that might trigger a certain release or pause a dead man release.

    There is also the possibility that his arrest and eventual extradition to the US could actually be a form or protective custody. Given all the damage he has done to HRC and Bill, and other under rock dwelling types he probably had a date with an unfortunate accident planned by them if he ever just walked free of the embassy.

    Knowing President Trump’s proven belief in pay back for dirty deeds done to him and family, if JA has the right goods, I would bet he would be offered a pardon / asylum deal if he helps permanently takes down the Dems and HRC.

    Remember when he was asked why he had not released any dirt on Trump his response was “there isn’t any” that implies he is an honest broker in that regard and would be seen as a natural ally by Trump.

    Michel de Notre-Dame!!!
    ” Un símbolo de la cristiandad en Francia o España arderá en fuego purificador ”

    Nuestra Señora llorará por todos nosotros y brillará en la lejanía.
    Con la entrada de la primavera una iglesia arderá en fuego, una gran Iglesia de todos los tiempos se quemará por los pecadores.

    El fuego quemará los símbolos que se han utilizado para el ego de los hombres y no en el nombre de Jesús.

    En Francia, España o Italia arderán las cúpulas para purificarse.

    Una gran iglesia se quemará para traer buenas nuevas.
    Prophecies of nostradamus

    Michel of Notre-Dame!!!
    “a symbol of Christianity in France or Spain will burn in purifying fire”

    Our lady will cry for all of us and shine in the distance.
    With the entrance of spring a church will burn in fire, a great church of all time will burn for sinners.

    The fire will burn the symbols that have been used for the ego of men and not in the name of Jesus.

    In France, Spain or Italy will burn the domes to purify themselves.

    “A great church will burn to bring good new ones.”

    The above is not my translation, just something that was brought to my attention by an old friend
    Once again Michel points out a signpost in the grand progression of time…pg

  12. E.M.Smith says:


    I thought the quatrains were in old French. That looks more Spanish to me… (Though I have a bit of trouble separating old forms of Romance Languages as they tend to converge eventually to Latin; and since I can read it anyway it is a bit mooted… more a “what was that language you just read?” thing.)

    It IS a bit spooky, then again, many churches have burned over the centuries. IIRC the one in Venice posted a comment they they had burned twice and recovered each time so Notre Dame ought to as well.

  13. cdquarles says:

    Hmm, Tuscan? I once saw some quotes that looked more French than Spanish or Italian to me; and those were Tuscan.

  14. E.M.Smith says:


    Then there’s Provençal… that grades into Catalan… and a few Italian dialects and.. I once found I could kind of read Romanian…

    I spent a while reading about the different minor Romance languages and learned a bit of Portuguese (after catching a flight from Florida back to California and finding a magazine, reading some about Brazil, thinking it a bit “off” for Spanish and realizing the flight originated in Brazil and it was Brazilian Protuguese).

    For many of them it is just a question of how much Latin was preserved, how much Celtic base was carried over from the original inhabitants (and mainland Celtic was very similar to old Latin anyway) and how much admixture of “a bit of something else” happened. So Spanish has some Arabic in it. Portuguese a different bit. French has more Celtic and German in it (those auxiliary verbs…) and Romanian has a bit of Slavic bleed in. Then how many old forms were retained. So once you’ve learned a core (for me, both Spanish & French) then it tends to just be some “odd bits” that you can often read around and get most of it.

    After a while I tends (at least for me) to become sort of a Romance Language Stew and any of it works in various combinations… IIRC Occitan (root of Provençal.and Catalan) has fewer Arabic bits than Spanish and more older forms that French. Still, it’s a pretty language that I can sort of read (some guessing on some old bits for fine meaning, some words alien).

    If I had to place that quote in one, I’d choose Spanish. Perhaps an old style of Spanish. I’ve read many of the quatrains in French and they were clearly French, if again an old form of it. Hombres and Nuestra Señora are pretty strong indicators ;-)

    Wonder what google translate will call it… back in a mo’…

    Yeah, it says “Spanish Detected” too…

    In case it did not make the news in the USA ;)
    IPA’s press release

    I’m here in Brisbane where I’ve spent the day with Peter Ridd, Stuart Wood QC and John Roskam. A few minutes ago we heard that Peter has won his case. Judge Salvatore Vasta has found that all decisions made by James Cook University against Peter – including his sacking – were unlawful. You can see the judge’s decision here.

    We’ll have more to say about this decision in the coming days but for now you can read the IPA’s media release here.

    In the next few months, we’ll be back in court to argue for Peter’s job.

    This is a wonderful victory for freedom of speech on climate change. Thank you to the thousands of people who have supported Peter’s case and thank you to the wonderful work of Stuart Wood QC, Ben Kidson, Ben Jellis and Mitchell Downes and Amelia Hasson at Mahoney’s.

    Thank you once again for your support.

    What apparently happened, is that the wildlife geniuses and experts of “Our Planet”, managed with their drones to drive the walruses into a panic. Right over the cliff.


    The drone or drones go up and the walruses go over the cliff. This is fairly straightforward.

    But yet, Global Warming got blamed by the drone masters.

    It’s bad enough the series’ experts and film crew apparently killed the walruses through negligence.

    But to add insult to injury, they then blamed it on “Global Warming.” As the political Left always says: “Never let a good disaster go to waste.”

    I’m indebted to Euan Mearns’ ( )Energy Matters blog for this interesting video.

    This video will probably make the Greenies heads explode, more cows (and their farts) equates to a better carbon cycling, less desert, and a greener planet. And this is not a theory, Allan Savory has done it, and has evidence of its worth.

    How to reduce desertification using livestock.

  21. E.M.Smith says:


    Yeah, I ran into that simple truth a year or two back. Forget where, but I think it was some TV documentary. Guy takes two fields, runs cattle on one, not on the other. One with cattle does a LOT better…. one without slowly loses fertility and desertifies…

  22. p.g.sharrow says:

    For 80 years the intelligentsia have taught that grazers cause erosion and desertification. Eliminate grazing and the world would return to being a park like Paradise. Well they got their Paradise! Massive destruction in Paradise caused by fire and flood because they KNEW all the wrong answers. The old timers ran cattle and sheep and used the timber and wood, generally with wisdom to conserve those renewing resources and burning off the waste as it accumulated. Now it is all PRESERVED from use until it all explodes in a holocaust…pg.

  23. Steve C says:

    Principia Scientific has a fascinating introduction to (yet another!) form of ice – Ice XVIII or “superionic ice”. Increase water’s pressure to millions of atmospheres and its temperature to thousands of degrees and, bizarrely, it freezes into hot black stuff … which *may* be at the core of numerous astronomical bodies. Water is weird.

  24. LG says:

    Contrary to Global Warming predictions, chlorophyll in the southern ocean is on the rise.

    The Southern Ocean is a key player in regulating the planet’s biogeochemistry, productivity, and climate. Ocean color data from two NASA satellites show statistically significant increases in the concentration of chlorophyll in all sectors of the Southern Ocean, particularly in the Sub‐Antarctic Zone and Permanently Open Ocean Zone. The smallest changes were observed in the Atlantic and Pacific sectors of the Sub‐Tropical Zone. These trends seem accentuated by higher chlorophyll concentrations during the austral winter. Increases in the annual and wintertime chlorophyll concentrations can have implications for the Southern Ocean biological pump and ocean productivity and higher trophic levels.

    Plain Language Summary
    The Southern Ocean is getting greener because the amount of marine plants (phytoplankton) has been increasing in the last 21 years. These changes appear to be happening faster during the winter, which suggests that the growing season is getting longer. This is important because the Southern Ocean has a big role in the biology and chemistry of the oceans, and in regulating the Earth’s climate. This work was done using 21 years of data from two NASA satellites.
