Comment: Dedicated "computer" glasses... (Score 1) 464

by Temkin (#48718845) Attached to: Ask Slashdot: Are Progressive Glasses a Mistake For Computer Users?

I have progressives for every day use. My eyes have gotten bad enough that I can't read my car's dash insturments without them.

I spend 10+ hours a day in front of a computer and if I do that in progressives I end up with a very sore neck. So I told my optometrist I needed a prescription for "computer glasses". These are single focus with astigmatism correction but not quite the full strength of a reading correction. This of course makes them useless for just about everything else.

Erm, you likely forgot the exact extend of the Kyoto goals?

Global CO2 emmissions are now primarily an emerging market issue. China, India, etc...
That is nonsense, it is just 2 years ago that China exceeded the USA CO2 emissions. And right now they are also working on limiting them.

Working on it, as in "keep growing them until 2030, while the US shrinks"... I should just quit work and go on the dole with leadership like this. Why bother?

This is why America has no friends. It's like you think polluting is your god given birthright and will continue to argue about it long after everyone else has accepted that it's a problem.

Remember that it's only cheap for you because you are pushing the cost on to other people.

The USA has already met our (not ratified) Kyoto goals, and exceeded them. Global CO2 emmissions are now primarily an emerging market issue. China, India, etc...

You should not be using port 25 unless you are hosting a mail transmission agent. If you are submitting email from a user agent, you should be using port 587.
Port 25 has been deprecated by the IETF for over a decade and is reserved for transmission, not submission.

Good advice for the unwashed masses, but... I have almost 20 years in email server software development... Unless you attend MAAWG, I'll keep my own council.

I have a $10/mo VPS at a major datacenter with static IPv4 & IPv6 addresses that hosts the primary DNS server for my vanity domain. My house has plain old boring dynamic address DSL with filtered port 25, etc... I have a Raspberry Pi running light network services on the house net. It runs a cron job that runs pubkey ssh into a no-shell account on the VPS. When that happens, a script rips $SSH_CLIENT and does a quick compare to see if it changed. If it has, another cron job on the VPS fixes up a record in my vanity domain with a 60 second TTL.

OpenVPN gets me around the port 25 filter...

Why am I explaining this to a low four digit?

Some places, even here in the US, have a choice of electrical provider, it is VERY rare, but does happen.

Certain parts of Texas have fully seperated the generation market from distribution. Distribution is run by a monopoly called Oncor, and they get to leech from your bill at a mostly fixed rate. You then sign up for generation with a variety of providers offering various contract terms. When I lived there I locked in a 2yr contract, flat rate at 8.9 cents per Kwh, and tried my hand at bitcoin mining via dirty old coal. But I could have had 100% wind or 100% renewable at even lower rates, but they were seasonal and they tended to have short terms. 3mo then you get dumped on the market again when the 8.9 cent deal isn't available. Longer term renewables ran 11 - 15 cents per Kwh.

This is the system California was trying to set up, but the mistake they made was to not seperate distribution from generation. Now they're stuck with a politicized PUC making decisions that deem 1 Kwh used by a company has higher economic value to the state than 1 Kwh used at my house. So I get a form of rationing by tier, and if I leave my computers on and do too many load of laundry, they start charging me 50 cents a Kwh. Just who get s to keep the difference between that and the actual generation costs is lost on me...

That may be true, but the rate at which all that energy is released does matter. The crude burned for many hours, whereas Little Boy was done in a few minutes, with most of the energy probably released in a few seconds.

Actually the primary in Little Boy was done in a mere 30 nanoseconds or so. After that it was all energy distribution, mostly as gamma & x-rays, and the resulting secondary effects... like the atmosphere becoming opaque to x-rays, followed by crazy fluid flow mechanical effects, and finally a thermal pulse resulting from the Compton scattering. But that's after the surrounding air finds it's electrons again...

Some day, you should learn about automated regression testing, which allows an entire regression suite of hundreds of tests to run after every commit.

Maybe then you'll have something sensible to say.

Not just that, we're discussing changes in the tip of their source repo. Not "released" code by any strech of the imagination. We're basically spectatiors, watching one of those Bob Ross "joy of painting" shows. The picture has yet to emerge. (hmmm.... accidental Gentoo pun...)

THE reason California's personal income taxes are so high is that nothing can be collected through property taxes. Property taxes in California are in a perverse way the same as rent control. The property tax pricing has gotten so far out of whack due to Prop 13 formulas that the only way the state can get any revenue is on personal income tax. Of course where people always own home, personal income tax is cyclical so a lot of the boom - bust cycle plays out in California's budgets because the state is levered up on the economy. Economy does well, everything is great. Economy does poorly, whole thing fall down.

Dig a little deeper:

Prop 13 sets municipalities AGAINST housing. Since they can't get their money in property taxes, they take a chunk up front in planning and permit fee's. Last time I checked, many bay area cities are charging upwards of $140k in planning and permit fee's to build a single family home. That means that the barest wreck of a house with a valid occupancy permit is worth $140k. So that jacks up the prices of all houses, and gives them one way to get around prop 13.

The next way is to encourage you to move every few years. If you stay in your house, they never get to reset the property valuation. My parents are paying tax rates that last saw a major adjustment in 1978. I work in tech, making good money, and I can't afford to buy the house across the street from them in the east bay neighborhood I grew up in. So I commute in from a horrible distance, and hope I can make enough coin to move back in closer. When I do, the cities get to reassess the value of the house I sell and the new one I buy. The result of this is the transit problems never get entirely fixed. Most of the bay area freeways were built in the 20 years following WWII. Now days they have simple bypasses and rail extensions that have 20 year planning timeframes, and 10+ year construction times.

On the whole, California has rigged its economy to blow bubbles. That's how the cities and municipalities get by with the wreckage left behind by 40 years of NIMBY, tax and spend on free everything vs. proto-TEA Party types, all with the ability to amend the state constitution with 50% + 1 vote... The rich banker types have it down.... Let the system blow a bubble, cash out & crash, reshuffle, repeat. The people are just pawns.
