Comment: Re:Jam drone frequencies? (Score 1) 175 175

This is not a technology problem.

The sale of RC aircraft may need to further regulation. So far it's been mostly a self regulated process through the AMA helping RC pilots follow safety procedures and comply with FAA rules. But most hobby shops will sell you anything you want without checking for an AMA card, but some of them do at least mention it to those new to RC.

A callsign, license and test, like done in HAM radio, seems like the obvious solution to me. Hobbyists need to understand the rules and be liable when they break them.

It's been self regulating until recently. RC pilots generally belong to the AMA and the rules for the AMA include putting your name and address inside your aircraft.

Theoretically the AMA also provides insurance for the pilots, but I don't think anyone has ever been able to collect on that in 50 years.

Comment: Re:RAID and automated backups (Score 1) 297 297

While I appreciate the suggestions to use software RAID, and I do prefer the flexibility and recovery of MD or LVM, they are not a panacea. Software RAID doesn't make a glitch in DMA to your multiple AHCI ports not erase your super blocks or write different data to each drive despite configuring the software to use RAID-1. (yuck, it was a real mess)

Ideal would be redundant controllers for each disk, I've worked on such products in the past, but they are too expensive outside of an enterprise environment. And even if you also support live offsite replication (like this product did), you should still do offline backups such as tape. All that fancy stuff just lets you recover from serious issues more quickly, it doesn't completely eliminate the need for backups.

At least someone here gets it. Even the industrial stuff is pretty much a figurative duct tape that loses support as soon as the last contract expires. And losing support on this stuff is catastrophic because most embedded SW products need persistent maintenance to keep going. I really do think the poor quality is an elaborate plan to for users to upgrade.

Instead of creating a building that stands for centuries or a machine that works reliably for decades, I get to design software for the technological equivalent of underwear. Sure it might look like a cool phone, tablet or game console, but it ain't meant to last.

Without life, Biology itself would be impossible.
