Comment Re:Once they make the effort to get H2 by itself (Score 1) 76

The turbines are a sunk cost and so there's value in conversion than turning them to scrap and building fuel cells.

There are no sunk costs around the turbines. The existing turbines will be replaced. From TFS:

In their place, the DWP will install new combined-cycle turbines that are expected to operate on a mixture of natural gas and at least 30% hydrogen with the ultimate goal of running entirely on hydrogen as more supply becomes available.

They're reusing the land and part of the existing structure on it. Almost everything else is getting replaced.

Modern combined-cycle gas turbines are much more efficient than that. Most new installations now get around 60% efficiency if not better, and the current record is 64.18%, set by a Siemens turbine at Keadby Unit 2 Power Station in the UK. The end result won't be 68%, but it also won't be 34%. Given the losses associated with electrolysis, the net is likely to be around 50%, which still makes it a bad idea.

If you're afraid of spreadsheets in the financial industry, you should probably just keep your eyes closed. The entire industry is built on them to a very large degree. I've been in IT for almost 30 years, and over most of that, I've seen Excel spreadsheets used throughout the various accounting departments of companies ranging from small operations of a couple of dozen people up to multinationals with tens of thousands of employees, with some banks in there. Some of those spreadsheets are enormous and are doing complex calculations across sometimes a couple dozen worksheets, where changing one number can take several seconds to recalculate everything even on a reasonably modern computer.

Unlock all interactions? No. Unlocking a specific interaction? Maybe.

For common uses (like the public web), the most likely approach to decrypting a specific interaction is to break the RSA (cert-based) on the outside and then the Diffie-Hellman (ephemeral per-transaction) on the inside, then recover the symmetric encryption key to decrypt the rest of the conversation. But this is not trivial, and it requires more work than to just toss the transaction into the quantum computer.

The ephemeral layer is where things get harder. Even if you can derive the RSA key on a regular connection, you've got the first layer, but the DH layer is redone for each new connection. (Some sites don't use DH, or are vulnerable to downgrade attacks where DH isn't used, but DH is pretty widespread.) Every ephemeral negotiation has to be individually cracked. Tor uses DH or x25519 on all connections, so each has to be individually cracked. It is expected that breaking an individual 2048-bit RSA or DH encryption would take several hours if one had a quantum computer of sufficient power. Cracking 3072- or 4096-bit RSA/DH will take even longer, if it's even possible on the same systems. However, we appear to be a long way from such capabilities, and the NSA isn't likely to use it to break arbitrary Tor connection encryption, saving it instead for much more practical items. As soon as the NSA has practical quantum computing, it's going to have decades of backlog to go through just for the international signals, and getting anything moved up in line is going to need a damned good reason.

As much fun as it is to blame Oracle ( dog knows they deserve it ), this reeks of incompetent project management government-side. I can almost guarantee not a single person knew even a fraction of how their existing system worked or what it delivered, so during requirement gathering meetings would rattle off insane "wants" and "needs", while ignoring the real needs and requirements.

Oracle, happy to charge you as much money as you authorize, just went along with it I'm sure.

When you look at all of Europe, it's more like a weekly thing, and sometimes a daily thing. The ones that make the news are the bigger bombs like the thousand-pound bomb mentioned in TFS or the rare ones that cannot be made safe and have to be detonated in place, which can mean a lot of new business for window installers even with dampening.

You can't be the "baddest kick ass person on the block" without having an effective ability to fight. That means weapons, and it means training on how to use them most effectively. When going up against the Soviet Union, that means a nuclear arsenal. We made plenty of mistakes along the way, but we also helped ensure through deterrence that the Soviets never moved on Western Europe, and we helped ensure through diplomacy that World War III never broke out.

Democrats sure don't. They want them to vote and everything.

The following red states allow felons to vote after completing their sentences (carceral sentences in some cases, or complete sentences and fines in others):

Alaska, Arkansas, Florida (1), Georgia, Idaho, Indiana, Iowa (2), Kansas, Kentucky (3), Louisiana, Missouri, Montana, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, and West Virginia.

That's the overwhelming majority of them. A couple of them have exceptions for certain crimes like rape and murder, but for the rest, if you can finish your sentence, you can probably vote.

(1) Sort of -- the state government has intentionally made a mess of the initiative that passed 65-35.

(2) While the Iowa constitution bars felons from voting unless they have applied to the governor to have voting rights reinstated, Gov. Reynolds (a Republican) has a standing executive order automatically reinstating voting rights of felons upon completing their sentences unless they were convicted of murder.

(3) Similar to (2), except that Gov. Beshear's executive order applies only to those convicted of non-violent offenses.
