It's mostly a United States problem that waste isn't reprocessed. This is now and has been done on an industrial scale in Europe and the U.K. for several decades. For some reason the United States, under the guise of non-proliferation, will not permit reprocessing of spent commercial nuclear reactor fuel.

The story in this article isn't news. Everyone knows how to reprocess spent fuel since before the 1960s. What would be actual "news" is the time at which the United States allows the well-proven, industrial-scale reprocessing to be applied to its own reactors.

Even Canada does it. The United States' nuclear energy policy is laughably stupid. It's a shame, really.

Thirty minutes is ridiculous. That is not "rapid" ANYTHING.

The only real solution is to streamline the process of swapping out battery packs, or, ideally, hydrogen fuel cells.

This is where hydrogen fuel cells really make sense. They are the ultimate battery pack. They are interchangeable modules. You stop at a filling station and replace your depleted fuel cell with a full one in fewer than five minutes.

I know Tesla has a battery pack replacement service, but it really needs to be affordable and streamlined and not require expensive robotics.

NOBODY wants to wait thirty minutes for "rapid recharge." The money spent on this infrastructure should, instead, be spent on optimizing the use of hydrogen fuel cells. They are the ultimate battery and they don't wear out.

The rule of thumb here is:
If the process you are expecting is not written into your agreement or documented as a matter of company policy, then the process is not done.

Likely you're not using a data center certified under HIPAA, PCI, SOX, SSAE/SAS-70, otherwise it would be documented and you'd already know.

Wow I remember Degrader, too.
There was a compatibility problem I had with my original Amiga 2500. It was supposed to be sold with 1 MB chip memory but for some reason it had 512 KB instead, and this caused so many problems until I discovered why.

We figured it was probably from a dealer swap or manufacturing line error, even though the Wikipedia article discusses that the A2000 could have 1 MB or 512 KB, the A2500 line was always supposed to have 1 MB of chip memory. Mine came with a real Amiga 2500HD sticker. *shrug*

We experienced timing-related problems in early demos when running them on a more modern Amiga.

However, the worst was running software written for PAL mode. The chief complaint about these PAL games was that the audio played at the wrong speed. Major offenders were games that play lots and lots of sound clips, like Llamatron. PAL mode always messed up the length of the sound clips so they get cut off or played at the wrong pitch.

I had an Amiga 2500 which was the one that came with a 68020+MMU accelerator. I later upgraded it with the 68030 accelerator and Univ. of Lowell A2410 workstation graphics. I also still own an Amiga 3000T with a QIC tape drive with Amiga UNIX and an Amiga 3000 with a floptical drive. Playing old demos is a pain in the neck on these new machines.

Great for GPIO, power supply, and USB. My only real concern is that the ethernet port is on USB. If you're like me and prefer the stability of ethernet, be advised that using ethernet will not only be slower but it will tax the CPU since USB relies on CPU power to operate. Not that this would be much different from using USB WiFi adapters, but it's something to keep in mind about the Pi.

This is an update to my previous Journal article "Optimize performance of EC2 EBS volumes and Amazon WorkSpaces." Along with writing each unused sector, Amazon also recommends reading from each sector. To do this we can use the Windows version of the "dd" command available at

This problem is as old as manufacturing.
Do we really not know or fail to remember that this is how the entire Japanese electronics and automotive industries were spawned? This is how the electronic industry of Korea came about, and one third of the entire Soviet Union's compute capacity from 1950 to 1990. Not to mention the entire DECSYSTEM-20 compatibles market and all the AMD, Cyrix, IBM, NexGen, WinChip, RISE, etc. x86-compatibles market.

I'm sure someone has already or will soon point out how this is newsworthy.

The devil finds work for idle circuits to do.
