I'll still prefer Marathon. It was better than Doom 25 years ago, and it's still better today.
And Marapfhont kicks the tar out of AmazDooM.
Tankless systems have the same corrosion problem. They also have the added benefit of scale reducing their effectiveness and eventually clogging them entirely. If your tanked heater was properly installed -- it has a catch pan and drain -- then the eventual pinhole leaks will not be the ruination you claim. Either way, preventive maintenance is necessary to keep them running for years. (my previous one lasted 23 years! The flue eventually burned through -- short of spraying it with the stuff used to protect welding tips, not much I can do to protect the steel from the fire that's supposed to heat it.)
(the ones at my parent's house (electric) have always rusted from the inside out because no one replaces the cathode rods)
who the fuck has a water heater that is network connectable
Mine can be -- iCOMM industrial control system. It's in my house, so it doesn't have one. And it wouldn't be "connected to the internet" if I did, but it would be connected to my leads-to-the-internet LAN.
Having seen numerous documentaries and tours of the UK National Grid, and various US grid operators, nobody runs at exactly 100%. A healthy grid is run with some excess capacity as a buffer -- while small, for obvious cost reductions, it's important to have that buffer to avoid brownouts due to sudden increases is load. (i.e. the exact thing the hacker is trying to cause.) I'll pick on the UK because their load has the grandest predictable spikes... when many "click on the kettle".
Because most people dumped Solaris more than a decade ago?
"Not entirely" as in [in my experience] many former solaris shops still have bits of solaris remaining. It wasn't "dumped", but incrementally replaced over the years. (solaris 10 was the real kick-in-the-ass to start moving... SMF, the systemD of the Solaris world.)
OpenSolaris was as much a marketing ploy as it was a means to remain relevant -- "Open Source" being the trendy new buzz word / business model. You could already get solaris for free -- for "non-commercial" use. (surprisingly, even under the infinite greed of Oracle, solaris is still available for free.) Sun was the only source for sparc hardware to run the OS, so they already had your money. (solaris/x86 never had much of a software market)
(Sure, anyone running x86 hardware is far better off moving to linux or even windows. The few solaris/x86 installs I knew were moved to linux and windows.)
Not entirely. I still run across the odd solaris 7/8/9 system from time to time. I still run one myself. You don't fuck with what isn't broken; there hasn't been a need to replace it, although it has been discussed. (maybe should based entirely on the power bill)
(I have several systems standing by for testing and troubleshooting whatever might come across my desk. But they aren't actually on.)
Incorrect. A growing amount of Cisco hardware is running linux. Old School IOS and Old School PIX aren't linux -- which shouldn't be a surprise as they pre-date linux, but modern ASA, NX-OS, IOS-XR/XE have a linux base. (XR started out with QNX and moved to linux ~5yr ago)
running on top of linux... on top of commodity merchant (*cough*broadcom*cough*) silicon.
Yes, software switches do exist (aka "bridge"), but, as you mention, they're slow as crap because software (general purpose CPU) has to move frames from interface to interface.
Amazon isn't "getting into the hardware biz". They're just going to (sub)contract that shit to any number of "white box" switch makers already gluing common Broadcom (etc.) switch SoCs to boards. The OS on those boxes will most likely just be a customized / rebadged existing network OS.
SDN is still mostly just Marketing Lies(tm). The only people to really do it, have been doing it much longer than the term has existed. And they do it with in-house designed technology that Works For Them(tm) -- and they generally don't share. (facebook and rackspace claim to opensource their shit. Good luck trying to use what little they've shared.)
I tell them to turn to the study of mathematics, for it is only there that they might escape the lusts of the flesh. -- Thomas Mann, "The Magic Mountain"
