You are not getting it: It has nothing to do with therapy vs. detection.

The article talks about contraband of radioactive materials. I gave you examples where radioactive materials are used both in therapy (certain kinds of radiotherapy for cancer) and in medical imaging (PET and SPECT). You mentioned none of these examples.

Instead, you gave three examples (x-rays, CT scanners, chemotherapy) none of which use radioactive materials.

Thus you used completely invalid examples to illustrate a very valid point.

(...) how they believe those countries can achieve medical procedures we use every day in hospitals and labs (not including Universities and other research facilities) without radioactive isotopes. Things like X-Rays, Chemotherapy, CT scans, and everything else found in a Nuclear Medicine office (which is a pretty long list).

I agree with pretty much everything you said, but you picked up precisely the wrong examples.

X-ray machines and CT scanners (which are essentially an x-ray tube and detector mounted on a rotating gantry) do not contain any radioactive material whatsoever. Yes, they emit ionizing radiation (in the form of x-rays), but it is not originating from a radionuclide. Other types of tomographic scanners such as PET and SPECT do employ radionuclides injected into the patient, but you precisely didn't mention those.

And chemotherapy... again, that uses chemical agents to treat cancer, not radioactivity. Yes, there is radiotherapy, which in some cases (but not always) relies on radionuclides to deliver an ionizing radiation dose, but again you failed to mention it.

The data for the US is almost laughably vague. It could very well be that 1000 requests were made, and 1000 requests were granted.

100% success rate in complying with requests sounds pretty cozy to me...

Following that exact same logic we could argue that 2000 requests were made (involving 3000 accounts) and 0 were granted.

A 0% success rate in complying with requests sounds pretty un-cozy to me...

I agree that the data is worthless, though.

You see you cant buy a disc with aperture on it, only via the app store... and if they remove it from the app store you cant reinstall it when your hard drive crashes. Therefore they CAN make it disappear. All they have to do is wait a short few years for that hard drive to fail.

No one is preventing you from backing up your apps. Why you refuse to do it is totally beyond me.

All the Macs I've owned have always been my main personal computer, and the first couple were my only computer at the time. I did everything on them: schoolwork, gaming, stuff for my dad's office and for others, etc. Looking back, I believe I spent way more time with them than I should have.

Did I experience system crashes with the dreaded bomb box? Yes, plenty of them. Did I experience sad Macs? Yes, occasionally. (I believe it was supposed to appear on hardware failure, but after restarting the computers continued to hum along for years). I never owned (nor pirated) a copy of Norton Disk Doctor, although I did see it running on other people's computers.

It's not my fault that my experience differs from yours.

Comment Re:Backup? (Score 1) 396

The parent post is assuming that the user is using Time Machine for the backups. In that case, the checksums are usually not verified (as nine-times said in his reply).

Nevertheless, in some cases Time Machine will perform a "deep" scan, for example if you have not backed up for a long time or if you upgrade your computer's drive. In that case, the corrupted file would be identified as a "change" and would be backed up again, just as you said.

Nevertheless, take into account that the corrupted file is not replacing the original in the backup. Both copies are left there so once you discover the corruption you can use Time Machine to navigate to a backup that is old enough and allow you to recover the file.

Anyone who owned a Mac since the 80s remembers having to use Norton Disk Doctor and later DiskWarrior at least once per month to repair the filesystem. Entire folders could go randomly missing each time you booted up your Mac, and if you accidentally lost power to your hard drive, the use of one of those was mandatory.

No, not "anyone who owned a Mac since the 80s...". My first Mac was a Mac Plus bought in 1987 (IIRC), and I have never used those tools nor experienced the problems you mention.

Thanks for the link to TFA. (I included a hyperlinked version for the benefit of the copy-paste impaired).

Reading that WSJ article allowed me to find the actual scientific paper in Nature Medicine , for those so inclined. Unfortunately it's paywalled except for the abstract and figures but those in the target audience of the paper probably have access through their institutions.

New York City water is untreated and it has some of the best water in the country.

Really? Cause I've read otherwise:

Before entering City pipes, all drinking water is treated with chlorine, fluoride, food-grade phosphoric acid, and sometimes with sodium hydroxide. Water quality and infrastructure are overseen by the City's Department of Environmental Protection (DEP) in coordination with the EPA and New York State 's Department of Health.
