Comment Re:For once I feel good (Score 1) 125

I've been to 38 states and 13 countries, the only other major city I'd want to live in is Chicago. Unless I happened to land a job near a L stop my commute would be worse than what I currently have here and that would still require me to give up my one acre lot with one neighbor (my other neighbors are a horse farm, working farm, and a half mile long driveway). The single downside is the cold during the winter but the upshot is we have actual seasons.

Comment For once I feel good (Score 1) 125

For once I feel good about one of these reports. I'd need 50% more to have the same standard of living in SF as here in Cleveland but I'm at 10% above the High range for my position in that market. That means I'm effectively making 155% of the max range, add to that the 7.5% retirement give plus 2-3% 401k match and the package at the new place is looking really, really good.

Dude, what kind of rinky dink operation are you working with that tech support closes at 5PM? It must be some single man WISP because even the small dialup ISP I started with in 1993 had 24x7 phone support. It is likely that the lineman who can fix a physical plant problem has limited hours for residential customers, but troubleshooting and diagnosis that could pinpoint an oversubscribed POP should be available around the clock. The idea that you're going to get a 100% commit rate circuit for $30-50/month is insane. The reality is that for most people ISPs do a fine job of keeping speeds in the usable range damn near 100% of the time, see the FCC 2015 broadband report if you don't believe me. The only consistently bad ISPs are Frontier, Windstream, and Century Link (I had forgotten the third, though there results prior to 2015 were somewhat better). Peak vs offpeak had little impact on the ratio of advertised to achieved bandwidth which means oversubscription was a non-factor.

(as an amusing aside the fiber plant that Frontier bought from Verizon shows significantly better results in the 80/80 test than the plant that Verizon kept, I wonder if they just never updated their advertised speeds or if they're actually managing it better than Verizon)

I'm sorry but that is pure BS, at my previous job we had hundreds of locations all over the US and Puerto Rico and the number of places that couldn't reach 80+% of their rated download speed 90+% of the time could be measured on one hand and most of those could be fixed with a call to tech support or harassing our account exec. The only unfixable locations I can remember were Frontier or Windstream DSL connections in locations with no alternatives so those bottom suckers didn't give a damn. This covers the period 2005-2015 so most of the period of widespread broadband in the US. Oversubscription just wasn't a meaningful problem in almost every instance.

A 2 carat H SI1 round lab created diamond isn't any cheaper than the same class diamond from Canada. I just did a quick online search and that's still as true as it was 15 years ago (I guess the DeBeers mafia has convinced enough folks that synthetic diamonds aren't as good that there's been little progress in the technology)

Yup, my wife and I decided that the only way we'd buy diamonds is if they came from a conflict-free source, which meant buying Polar Ice diamonds from Canada as they were the only source not tainted by DeBeers that could be reliably traced (I'm not sure if the situation has changed since we made our decision, that was 15 years ago and the conflict free movement has received a lot more support since then). We paid a slight premium for the stones, but the fact that they were being custom set was the major expense (using local labor is quite a bit more expensive than having kids in China or wherever set the stones, but again worth it from an ethical standpoint).

To put some numbers to it
Cisco 3064 switches:
3064-X 64 ports of DAC @ 143W = 2.2W per port
3064-T 48 ports of GBaseT and 4 SR4 uplinks @362W = 7W per port

Brocade 6740 switches:
Brocade VDX 6740 48 ports of DAC and 4 ports of 40Gb QSFP @ 110W = 2.1W per port
Brocade VDX 6740T 48 ports of 10GBaseT and 4 ports of 40Gb QSFP @ 460W = 8.8W per port

24x7 operation at $.10/kw ~= $1/W/year so each port of 10GBaseT costs you ~$9-13/year (two sides to the link) over DAC, that would eat up the cable savings pretty fast. Add in reduced reliability and higher latency and it's not too surprising that 10GBaseT hasn't taken off.
