Comment Re:iPad 1 anyone? (Score 1) 434

No, because they're too busy re-launching the crashed browser because the inadequate RAM on the device makes it choke and die on today's Javascript-heavy web pages.

The iPad 1 is a great tablet for letting your kids watch movies on an airplane, but it's obsolete for most every other use. Even my wife, who would still be watching TV on a 13" tube set if I hadn't given it away, finally gave in and bought a last year's iPad air versus putting up with it any longer.

IMHO, the iPads are pretty decent at longevity -- I have 8.3 on my iPad 3 and it's arguably no worse than it was on 7.x.

I think Apple could benefit everybody by doubling (or more) the RAM they put into iPads. New OS releases and expanding app capabilities eat into RAM to the point where you can't keep apps cached in RAM long enough and app switching becomes app re-launching and the inevitable grinding away as they refresh paged-out objects from the network.

IMHO this is what makes them slow/crash/obsolete. I'm sure the iPad 1 with 4 gigs of RAM would still be pretty useful.

It's a good question.

When our house was built in 1957 it had a fuse panel. Someone in the late 1970s/early 1980s upgraded it to a 100A breaker panel and did some significant wiring changes.

When we remodeled in 2003, I had the service upgraded to 200A and beat the total chaos of rewiring by having the new service feed a 200A panel and then fed the old panel from the new panel, deftly avoiding the chaos of trying to rewire a hot mess of Romex, BX, flexible metal conduit (original to the house) and EMT to a new panel.

A commercial electrician I used to work with did the wiring when he built his house and piped all of it, most of it in 1" EMT with a couple of strategic junction boxes. In theory he could rewire relatively easily by just pulling more wire in existing pipe.

I always kind of wondered why houses didn't go one better and have raceways integrated into them.

Comment School me on well water (Score 0) 328

Is "well water" (drill hole into water table, pump out water) always used raw and unfiltered? Has it traditionally always been safe to drink anywhere you can sink a well, or is there some history of bad wells due to natural contamination?

Every home I've ever been that had well water at least had a water softener and often had issues with high iron content. A woman I worked with who grew up on a farm said they had to buy bottled water (the giant kind of bottles you see on old school water coolers) for visitors because they had some kind of low-level bacterial contamination her family was immune to but would make guests sick.

It seems like it would be common sense anymore to have a whole-house reverse osmosis system if you had a well. If not for health then for not choking your plumbing with mineral build up and making your washing machine and dishwasher work.

Do you understand what 'rich fuckers' do now? They pay property taxes at an obscene rate to fund their local public schools and then leave the public school system to privately fund their children's education elsewhere, leaving more money in the school system for the other students.

I think it depends on how you define "rich fuckers". Astronomically, family-dynasty rich? Sure, they pay big property taxes either in an urban school district which is so chronically underfunded and mismanaged that their generous and unused contribution doesn't make a difference or in some elite suburb which is so generously funded their contribution doesn't matter. And they're so rich they don't care.

On the larger scale though, the HENRY (high earner, not rich yet) generally flock together in affluent suburbs where their property taxes are pooled to fund really great school systems and where housing prices and housing policies basically redline the non-affluent out of the district.

The real benefit of this isn't the money per se, but the way it keeps out the problem children of the urban wasteland -- those whose parents don't participate in their kids' education or really provide any structure in their lives. These kids are the drag on urban school systems through discipline problems, the extra work required by teachers to get them back to any kind of baseline, special education needs, etc.

An average funded school district can educate children well if the kids have some kind of parent-engaged baseline to start with.

About their platforms, especially the iPhones. I would expect them to be as or more so with a watch. I wouldn't expect this port to remain usable, in the same configuration or even be there in the future. Because that's how they work.

Most of the time I sort of buy the benevolence in their designs (ie, the lighting port on phones) although generally speaking I think they're too controlling and they actually limit things you can use the devices for.

Comment Re:Another market overlooked (Score 1) 317

Maybe I wasn't clear -- most houses have a single panel with multiple circuit breakers. Each breaker services a separate circuit. Each circuit represents a single run (hot, neutral and ground) from the panel to the destination. Only really old houses that haven't been upgraded use fuses. The panel itself has two buses, one for each 110v leg, a common neutral bus and a ground bus, a main breaker which controls the entire panel. The legs aren't switchable.

The fuzzy part is the "destination". Since each circuit is usually breakered for 15A it can support more than a single outlet or light fixture. When an electrician wires the circuits, they commonly will run the cable from the panel to, say, a socket and then feed off the socket's secondary terminals (or via wirenut splice) to another close by socket or light fixture. And "close by" doesn't mean "in the same room" or "the same type of connection" -- if there was another socket on the other side of the wall installed at the same time, because the distance is close and it's easy for the electrician they will often connect that socket to the same circuit as the first one.

What you end up with is basically a parallel circuit of devices (light fixtures and sockets) that are close together "as the crow flies" but not necessarily in the same room or a common type of connection (socket or light fixture). This is especially true of remodels or small-scale room re-dos or where people have wanted additional outlets and rather than rip out a bunch of drywall, they will tap from the closest place they can.

Large draw devices (central AC, electric stove, hardwired electric heaters or furnaces) will have their own, dedicated high-current breaker at the panel and a dedicated run from the panel to the device. It used to be allowed years ago to even tap off one leg of a 240v circuit to get a 110v, but codes are tighter and these days a new install will require a dedicated run.

So what you usually end up with a single panel with a handful of dedicated breakers for high-current and 240v devices and then a bunch of other breakers which control the outlets and fixtures in a specific area, but which may also control other outlets/fixtures "nearby" often with no logic other than what made sense for the electrician when the wiring was done.

What I think is needed is much stricter cabling standards and structured panels. One panel should control lighting with a dedicated breaker for each room and ONLY fixtures IN THAT ROOM connected to it. Another panel should control general purpose outlets by room. A third panel should control high load devices (electric stove, central AC, other major electric appliances). A fourth panel for "mandatory devices" you would always want priority given to, such as refrigerators, furnace blower motors for gas or oil furnances, etc, perhaps a few "emergency" outlets for computers or USB chargers).

With a properly structured panel system a transfer switch could then feed the lighting and mandatory device panels but leave the high power devices and general outlets off until mains power is restored without risking overload of the backup source or from vampire loads connected to standard outlets that aren't critical during a power outage. Of course this is a lot more expensive to install because you need much more cabling, more panels and more wall space to place the panels.

A better option, IMHO, would be a smart panel or maybe even smart breakers which could be individually controlled so that you can assign the basic panel "values" and determine which ones to run under specific non-grid scenarios. Such a control system tied into the backup system's monitoring and capacity could then switch off or on circuits as power was available or as loads were brought up/down.

As is right now I just don't see the Tesla home battery as providing enough output to be meaningful for anyone who's not facing extremely high grid prices and using a large solar install with the battery to pull from at night.

The 2kW output isn't enough to serve as a whole-house backup unless you're already a fanatic about conservation or are willing to run around killing high loads when you lose grid power, and the 5 hours runtime you'd get from the battery @ 2kW isn't enough runtime.

In my mind, the inverter add-on is only part of the wiring issue. Most houses have a central breaker panel that terminate all the circuits and any whole-house system would have to feed this panel (risking overloading the backup source and requiring manual shut off of any automatic loads that might kick in). Or, more sanely, do some extensive restructuring of loads so that light/must-have loads are on one panel and high loads are on another so that when power transferred you'd kill heavy loads automatically.

What would be nice would be a smart panel that could be programmed with never/always/switchable values for each circuit and the ability to set priorities for them so you could maximize runtime and guarantee power.

Further, I think the wiring practices of residential electrical need to get a whole lot smarter. I'd like to see a dedicated panel for each of: wall sockets, lights, appliances, and "high load" appliances like central AC, electric stoves, and electric heat with a dedicated breaker for each room services by those individual panels.

Currently residential electrical wiring practices don't do this at all -- they run the shortest feed from whatever place they can, resulting in outlets sharing breakers with lights and often crossing rooms. When we remodeled I mandated some outlets be on dedicated breakers and in both instances found those "dedicated" circuits fed to other places because it was convenient for them. I made them change them but it was a fight.

Comment Re:2kW isn't enough power for a home (Score 1) 514

Why would you do that? Every single one of those things has an off switch. In all but extraordinarily rare cases, use of every one of those things is discretionary. You don't need to rewire your panel in order to keep the house running during quite a long power outage. Just don't use heavy draw appliances. If you are affluent enough to buy one or more of these battery packs in the first place, you can certainly afford to buy a few paper plates and an extra pair of underwear, if it comes to that.

What happens when you're not home and the base load goes away and the battery kicks in and your draw exceeds your output capacity? Maybe if you're actually home you can turn off anything high load or that's discretionary, but if you're not you'll overload the battery and I'm assuming it will either current-limit itself via voltage drop or just plain shut off output, which is probably the sanest/safest to prevent damage.

What would be nice would be a smart panel that kept track of the load on all the breaker legs, each of which could be assigned a priority level. Loads could be assigned "always off on battery", "switchable", "always on" and the system could disable switchable loads to ensure that there was sufficient power for always on loads, and the priority setting could be used to switch off "always on" loads so that the highest priority loads could keep running as battery levels dropped.

Regardless of your individual situation, it's a gamechanging device for the vast majority of the world.

I'm not sure how gamechanging it really is.
