Re: Feasibility of Common/Shared Cellular Network

The discussion about GSM vs CDMA is old news, CDMA lost. LTE is GSM based and even traditional CDMA operators like Verizon are operating LTE network. It's.... complicated . The tl;dr for that link: LTE is neither GSM nor CDMA; within LTE, some carriers still use time slicing instead of frequency sl...

Re: Feasibility of Common/Shared Cellular Network

I don't see it happening in the near future. Verizon has managed to outbuild all other competitors with nationwide 4G-LTE coverage on a CDMA backbone, but charges a premium price for it. AT&T/Sprint/T-Mo have expanded considerably but only AT&T has (GSM-based) coverage that is comparable to ...

Re: Replace Incandescent Indicator Lights with LEDs

I would switch to color-matched LEDs and omit the bulb sleeves. Gives a bunch more options and the LEDs can be run with higher-value dropping resistors, ensuring long life. The epoxy housing is a solid casting around the inner die, which means you can shave the "lens" tip with a file or sa...

Re: AMD CPU power management in Kubuntu 14.04

Assuming this info is correct, there's only one temperature sensor on that entire die and you're probably fighting a losing battle attempting to get useful information out of it.

Re: Anyone repair anything today?

Otherwise, the ONLY rule that firmly applies to how things might be daisy chained, is that no circuit jumps between different floors. My current house (built in the 1980s) breaks that rule. All of the bathrooms on the 1st and 2nd floor are wired through a single GFCI breaker located in the upstairs...

Re: Anyone repair anything today?

The other half of my accident is because this house was still wired by a drunken sociopath: I'd turned off the breaker for the bedroom, but it turns out that the outlets along the outside walls of that bedroom are on the same circuit as the bathroom (not even a shared wall)!  Because that makes som...

Re: DYMT: Imi's Legacy

I've heard terrible things about the Humvee's off-road (and on-road) capabilities. Everyone I've heard seems to say it was completely underpowered without the add on armor and with the doors and roof removed. Maybe, it was something like just 150hp although the diesel torque curve would give reason...

Yup, that's the one. But this one definitely was late 1950s or early 1960s.  Our group's resident vintage CJ owner/enthusiast chatted up the Benz driver a bit later when they pulled off for their own lunch break, but I don't remember the exact model year.

Heh. Given what I've heard about Humvees, it seems like it is a terrible idea to buy one of these. What do you gerbils think?

Re: Checking Ethernet cables

A less-obvious indication of an "iffy" connection is to keep tabs on the connection rate. If you connect gigabit hardware and it has a tendency to randomly drop back to 100mb, then the jack connections are probably not very clean. The problem with having an electrician pull your networking...
