Comment Re:What moron puts IPMI public facing? (Score 1) 102

Oh Supermicro has plenty of fault. IPMI in general has been vulnerable in many ways since day one, far to many devices would lock up if exposed to general internet noise for to long. Since it's something you do not access often and generally them in an emergency that is a really bad combo. You might know them by the name of a DRAC or ILO card.

Pico cells and similar do just that create smaller and smaller cells while using the same spectrum as the towers. Devices like the airvana's do this at a tiny scale so a home or small office can put a tiny tower in and backhaul via voip. I've used larger version that were a tower just for an office building.

You need not add more wire, putting in a strand of glass to every location from a central point is worth doing as it need only be done once. Anyways the point a cell based network is to divvy it up into small segments to use the same spectrum over and over again.

As it relates to net neutrality it's all BS, beyond prioritizing an emergency services call over everything else.

It need not be bad ram. If your not running ECC from top to bottom a stray bit of radiation etc will flip a bit every now and then. ECC lets this be detected and corrected. This can be an issue with the whole chain and is a tradeoff calculating ecc means added latency, requires buffers which in themselves give more places to have a bit flip.

Work with them for a bit assign them in a sensible manner. Been using IPv6 for a long time you remember your prefix fairly easily. I've got the ipv4 address of all my servers coded into the ipv6 address in human readable format. So I just go 2001:abcd:1234:5678::10:10:20:53 for 10.10.20.53. I do not work with desktops or "random" dhcp everything has consistent IP's.

To make it worse the data lines are used by many devices to communicate capacity of the charger so you can not just cut them (and charge about the spec 500ma). A couple company's effectively make a hardware condom that lets the charging capacity be determine but no data. Now if your device has something like a Qualcomm PM8921 that does not need the resistors it keeps pulling more power till it see's voltage drop and backs off (oversimplification), these are in the newer nexus line. Things get tricky again with USB3.1 as it's got more power negotiation, with the usb power delivery spec allowing up to 100w (5a 20v) and thats about a year out.
