Comment Re:Sun's surface temp (Score 1) 156

The article says "roughly a quarter the temperature of the surface of the sun". 1000 could be considered roughly 1400. The hottest solar concentrators I've read about were just under 600C (~580). I don't see anything in the article or summary that suggests 1000 is approximately the temp of the sun's surface.

Instead of releasing stored energy from within the earth's system (aka, burning fossil fuels) and releasing greenhouse gases that help trap the sun's energy, we're just going to cut out the middle man and trap the sun's energy directly?

What middle man?

One process creates a bunch of localized heat and releases greenhouse gases that help to trap heat long-term. The other process creates the exact same amount of localized heat and doesn't release greenhouse gasses.

Since no one ever checks signatures properly, stolen cards can easily be used for fraud in the US, without needing to shoulder surf for a PIN first.

Some notes on this... Merchant agreements PROHIBIT merchants from asking for ID and DO NOT REQUIRE that merchants check signatures. In fact Visa et al actually essentially PUNISH vendors who do. Famously, Wal-Mart used to have a policy to check signatures and VISA successfully argued that they should not be on the hook to cover fraudulent purchases that Wal-Mart should have caught via signature checks (ie, they said Wal-Mart's employees were inconsistent). So over 10 years ago Wal-Mart changed their corporate policy and cashiers are instructed to NOT check signatures. The same amount of fraud happens, but VISA et al are now on the hook and can't blame Wal-Mart employees.

In Europe, the card vendors were forced by law into Chip+Pin. VISA has more profit that the GDP of many countries and they don't even loan out money. They don't care about a little fraud. Their concern in the USA was users might periodically forget their PINs and pay with cash instead. So they lobbied to keep signatures, and of course our congress persons don't listen to security experts if corporate interests disagree.

That pesky atmosphere getting in the way won't make it easy, especially with high altitude winds in the 250mph highly likely. Heck, 253mph is the known record for a storm near the ground.

Alright, so let's build this space elevator on the moon, then. Problem solved, once and for all.

Do a Google search. While we have strong enough material to build it, it would have to be much, much longer than a Earth elevator. Earth rotates once ever 24 hours, the Moon once every 28 days. IIRC it would reach beyond the first Lagrange point.

Most buyers who purchase fixed income securities do it for the "fixed" part. i.e. you get a steady, lower-risk stream of income. A new unknown, potentially highly fluctuating instrument (based on the variability and fraud rates for cryptocurrencies) is the opposite of that.

I don't think this is true. The bond pays in Australian Dollars, a nice stable currency. I believe the point of the bond is that it can be traded off the exchanges and be self settling, without the need for a transfer agent. .

I think a NEWCOMER would have trouble with Sandman. I found it to be rather dense material with some crazy subject matter that jumps around in time and character perspective a fair bit.

It is adult material, in the sense of not only therms but in complexity of material. It does have the virtue of being mostly self contained - expect maybe for the first 8 issues. You don't need to know much in the way of comic lore to read it.

Gaiman's 1602 has a good take on the Marvel Universe. Also the illustrated Stardust is not technically a comic book but a very good hybrid.

I would second this. The comic books are not a genre, it is many genre. Superheros are common. Self published black & white biographies are good, for example, Maus, Ghost World, and Persepolis. Japaneses manga coves robot warriors to brewing sake to the swim team.

Squire Girl has good humor. Saga has great visuals. etc.

If the first does not grab you attention move on to the next. It is like going to a librarian and asking for a good book.

It encourages savings in financial instruments like bonds. Bonds get a little extra boast from deflation. Who holds bonds? Those people who are already wealth.

It discourages investing in equity. The hurdle rate for the Equity Risk Premium just jumps up by a little. Equities are better at weathering inflation than bonds.

So, deflation helps those who are already wealthy and encourages low risk low reward projects. It discourages the young hungry people from making big transformation projects. The general consensus is that low steady inflation is the best choice among the various options out there.

Yes, WebDAV is still around. It's not a bad spec, really useful in corporate environments.

I'm seeing complaints about Chrome's disabling of data: in the navigation bar having broken jsPDF, and that makes sense -- if they try to translate a PDF file into HTML client-side and display the temporary result in a new tab, it'll fail. The same would be true if you were generating SVG or PDF content on the fly and pushing it into a new tab for display (graphing libraries, report-generators, etc. that operate client-side rather than server-side).
It does look like they kept the functionality working as long as it's in an IFRAME, but those can get ugly to work with. At least we won't be the only ones scrambling to create workarounds...

There are legitimate uses for data: URI in the navigational bar, too. I have one that I'll have to recode now, that was the result of having to work around the horrible lack of useful WebDAV support in modern browsers. Popping a new page up in a separate tab (to not mess up a single-page-application) to then do a redirect, etc. was the solution I had to come to, after Firefox killed plugins that don't meet their security requirements (which we don't for our in-house extension, because it uses the Registry and launches apps, to try to get around the same problem of poor WebDAV support -- none of that will get past today's plugin-signing process, so the extension has to die.) Data URI were a quick and easy solution for serving up temporary content in a new tab, which I'll need to replace with some kind of server-hosted page ... not at all impossible, but dang it, I had it working and it was simpler. Phishers ruin it for the rest of us.

The Fed is a hybrid system, both public and private.

The Fed is owned by its member banks. They get to elect board members to the regional boards. Profits accrue the banks, kind of. The Fed doesn't pay a dividend so those profits never get monetized. So de facto profits go the Treasury.

However the Board of Governors is appointed by the president. This limits the amount of control the banks have over the institution. So what is ownership without access to profits or control?

A analogy would be the local co-op grocery store. The more you buy the more of the store you own. However this comes back as store rebates and the insiders still have control.

We are wandering a bit off topic, but... It is not a Middle Age thing. For most of history the best guess is that investments have returned around 1 to 2%. It may not even be a stagnation thing. Remember that returns are set by supply and demand. One could have a high growth rate and a high savings rate which would result in a low return on investments. A good example here would be the 19th century Europe. High wealth inequities probably pushed down investment returns here.

Perhaps the market is expecting the low-yield regime to last that long... no major expansions or growth opportunities in sight---unless something really great comes along (e.g. fusion power, self driving cars, automation, etc.,) the next 40 years will be pretty much like the last decade as far as growth is concerned.

Maybe. The rate is determined by supply and demand. There is surplus savings sloshing around the market right now. Pension and banking regulations, surplus savings from Asia, demographic imbalances. etc.

Even if there is a great leap forward this may not solve the imbalance. Take self driving cars. We could see a huge fleet of personally owned cars replaced by a smaller fleet of self driving taxis. Car production could fall by 70% in 20 years. So less investments would be needed. Most of the technological advancement over the past 20 years has reduced the amount of capital needed. No magic bullet here.
