for some silly reason I keep wanting to call it Thulsa Doom. Musta read too much pulp scifi/fantasy as a kid.

I recently had OWASP brought to my attention, someone was trying to use their security hardening guidelines for the postgresql database server... trouble was, that guide was written 10 years ago and hasn't been updated, while postgres has undergone steady and constant enhancement, with a major release about every 18 months, minor releases every month or two...
and don't forget...
a moderately popular web forum I'm on currently is infested with some sort of trojan that as long as you've got the site open, it eats 100% of one CPU core, and taps a WebSocket at a .ru host every few seconds with a encrypted message/response ... googling the .ru host name shows it on various lists of coin miners.
death to spammers!
Are your IoT gizmos, music boxes, smart home kit vulnerable to DNS rebinding attacks? Here's how to check
no interest? I'm 63, and I use Spotify extensively. My collection of 1000s of CDs is collecting dust. wrangling my MP3 'rips' onto various player platforms was getting just too annoying.
now, my FAVORITE way of listening to music is live, at concerts, primarily at places where listening is the norm as opposed to partying/drinking/yelling.

this was a city street, not a highway. 3 lane one way streets, quite frequently the left lane is full stopped because someone up ahead is making a left turn and waiting for pedestrians, are you saying the other two lanes have to stop and wait for the left lane to move before they can proceed? HAHAHAAHAHAHHA, right.
Re: I heard...
battery backup (or on newer RAID controllers, flash backed writeback cache using supercaps) only protects the write cache in the RAID controller. we're talking about write cache on the DRIVES, whihc is something desktop drives often have in write-back mode, but server drivers should always be write-through.
amazon's own webpile couldn't deliver my order history a hour ago....
I love the CIO's that mandate all internal critical systems are running on high availability high grade hardware, with redundant fiberswitches, multipath network connections, san storage, etc, then decides its all too expensive so outsources things to the likes of Amazon and Google, who are using the *cheapest* of commodity hardware they can get away with.... The irony of this escapes the suits.
1st, Chinese off-brand (UltraFire, etc etc etc) 18650s that claim 3700 mAH or whatever rarely even have 1000mAH. I've tested several batches of these and found no more than about 800mAH discharging to the 2.5V minimum safe voltage at a one hour discharge rate.
2nd, ANY device like this should be using the slightly more expensive PROTECTED 18650, NOT the unprotected ones. these usually have a button on the + end instead of a recessed contact, and are slightly longer. Unprotected LiIon batteries are only safe if they are permanently installed in a system with a integral protection circuit. the protection circuit prevents overcharge, over-discharge, and limits the max current output.
many many years ago (ok, was about 1975), I was working for a small computer company who had a customer that was a exotic steel alloy mill. the factory was full of these enormous arc furnaces being used to make fancy aerospace alloys. the computer was in a portable building on stands in the middle of this factory. we had to cover the whole porta building with copper sheeting, soldered together and grounded at multiiple points with 2" wide braid, heavy copper screens over the windows and door, to keep the EMF from crashing the system. we had to isolate the power with a motor+generator where the outside power grounds were NOT connected to the copper cage, only the generator was (and massive ground stakes). thankfully this was before networking was common, so there were no external connections to this room, not even modems. lets not even get into the problems we had caused by microfine metal dust getting through the ventilation filters and into the systems, those were mostly mitigated by stacking multiple air filters and changing them weekly, and keeping positive pressure in this room by way of enormous fans (outside the faraday cage, powered by the building power).
btw, in those old days, at least, those trolley busses didn't have any batteries on them, when the trolleys jumped the wire, the bus lost all power and lighting. hydraulic DRUM brakes didn't need any sort of servo assist, thats a feature of disk brakes, and I suspect those old busses would have had drums. I have no knowlege of what they run now, I've not ridden on the Muni since about 1970...
