Odds Of Survival

I’ve often (only half) joked that there are billions of people alive who have never died, so why should we consider it inevitable?

Well, someone has actually worked out the ratio. Hey, 7% odds of survival beats zero.

Mortality Hourglass

Speaking of which Peter Thiel seems to finally be getting serious about longevity, not only funding non-profit research, but actually investing in companies pursuing it.

Virtual Machines

So I ended up installing Windows into one in Qemu. Now I can’t get out of it. I thought that ctrl-alt-L would release it, but nothing happens. I somehow got into a full-screen Windows mode and can’t get out or even see the virt-manager. Any ideas?

[Update a while later]

OK, I figured it out. I’d accidentally clicked on “Full Screen View,” and had to get out of that mode to release the mouse and keyboard, by getting it to drop down from the top.

OK, next question. Anyone know how to make a physical NTFS partition viewable by a virtual machine?

[Saturday-morning update]

I decided to try to look at the drive by making it a share on the network, through the virtual ethernet port, but I can’t get Samba to work. Maybe Winscp?

How To Boil A Journalist

Some thoughts on the evolving “consensus” on climate science:

…there never has been a “crunch point” forcing journalists to re-examine the issue. Instead they have just kept the same ridiculous views for over a decade even though no sane journalist coming to the subject of “global warming” after 18 years of pause, complete failure of climate models, global ice back at normal levels, no increase in climate extremes, a decrease in hurricanes and children still knowing what snow is … no journalist would swallow this non-science about doomsday warming in the face of NO EVIDENCE to support it. (Rookies might be more sceptical, but they probably quickly get indoctrinated into the journalists alarmists views)

They don’t ever look at global warming afresh. They just keep believing the same non-science they have for over a decade despite the overwhelming evidence against their insane views.

The fever (to borrow a metaphor from the alarmist-in-chief) will have to break at some point.

Naomi Klein showcases everything that is wrong with climate alarmism.

Solar Radiation In CMIP5 Climate Models

has huge basic errors:

Why wasn’t this astonishing, large error of basic astrophysical calculations caught billions of dollars ago, and how much has this error affected the results of all modeling studies in the past?

The paper adds to hundreds of others demonstrating major errors of basic physics inherent in the so-called ‘state of the art’ climate models, including violations of the second law of thermodynamics. In addition, even if the “parameterizations” (a fancy word for fudge factors) in the models were correct (and they are not), the grid size resolution of the models would have to be 1mm or less to properly simulate turbulent interactions and climate (the IPCC uses grid sizes of 50-100 kilometers, 6 orders of magnitude larger). As Dr. Chris Essex points out, a supercomputer would require longer than the age of the universe to run a single 10 year climate simulation at the required 1mm grid scale necessary to properly model the physics of climate.

But let’s get a carbon tax, right now!

WordPress Problems

So I’m slowly beating the site into submission, but running into a few issues. First, I’m using a child theme of TwentyFourteen, in order to avoid making changes to the main templates. The way that works is that I add changes to the child style sheet, which then supercede the parent. But there are some things that can’t be fixed with the style sheet. For instance, in order to move things around in the post, I have to actually change the PHP code in the templates, in the parent. Another problem I’m having is that, in theory, a new function file in the child will override a function of the same name in WordPress. I want to display the time along with the date on the post, which is generated by a function called “twentyfourteen_posted_on” (the original can be found here). It retrieves the date, but not the time. In order to get it to do so, I’d have to modify it. But when I copy that into my child theme directory, and make changes, nothing happens. Anyone have any idea what the problem is, or how to troubleshoot?

[Update a while later]

OK, I think I figured out the problem. Apparently you can only override functions that are in the function.php file, in the main template directory. This is a tag, buried in the “inc” directory. So I have to edit it in there. Which means that I’ll lose the changes if I have to update the template. But it’s not a huge deal.

The Soon Et Al Paper

What is right, and wrong with it.

It’s always worth noting that the notion that CO2 is a greenhouse gas has never been in serious dispute, or even that the planet has been warming, in fits and starts, since the end of the LIA. The issue is feedbacks, and the limits of our ability to model them. We will probably get better at that in the future, but we currently suck at it, and it would be insane to base public policy on the models.
