It really disappoints me, what happened to Mexico. Movies set in the 1960s made Mexico look like its urban areas were just about on-par with urban areas in the United States at the time, and while rural areas may have been poor, there were and are lots of poor rural places in the United States too.
When we used to go toward Baja when I was a kid it felt much poorer than the US, and fairly recently when I took a cruise that stopped on the coast of Baja, the port we stopped at was just awful. I've seen commercial ports and abandoned or closed commercial ports in the US in Boston, San Francisco, San Pedro, San Diego, and on the islands of Oahu and Kauai. They all looked better than the one in Baja. The city we had to go through looked terrible too, broken monuments and public spaces, armed checkpoints that the excursion bus had to traverse, nonfunctional traffic signals, and trash EVERYWHERE. I felt more comfortable with a broken down rental car in Chelsea near Logan Airport than I did riding on a moving bus in Ensenada.
It makes me sad. Mexico didn't have to end up this way.
Correct. Even Cat5 in short runs will probably work at gig speeds. The biggest thing that hurts speed is the fluorescent ballast. Homes generally have few of those (though my late-seventies-trendy home is a glaring exception) so it's easier.
When I do my house, Cat6a is the plan. Main stumbling block is locating the MDF, I've got a couple of possible nooks to use, but all will require some moderate construction. Nothing I can't do myself, but laziness and other demands on my time make me hesitate to start.
And Debian is for when those gurus get tired of manually maintaining hundreds of boxes.
Seriously, I've been dealing with an ancient legacy Slackware install at work that's being phased out. I expect to put in Debian boxes with a deb repository so that I can keep the rest up-to-date by maintaining the package server. These boxes are there to be used, not simply to be maintained. I don't want to have to fight with libraries and dependencies just to deal with simple commandline utilities. I've had this problem with the Slack boxes; libraries never installed in the first place, libraries so out of date that even compiling from source with gcc not an option, etc.
If you're using zip-ties in cabling then you're behind the times. We use velcro. They actually sell plenum-rated velcro.
The bend-radius of Cat6a might be worse than 6 or 5e, but it's not so bad as to be a problem if you're smart about your penetrations. Besides, if your bend radii are so tight that you can't use 6a, those pullstrings are going to be useless down the road as they won't manage to let cables pass.
I don't like daisy-chaining L2 devices like that when there's not a lot of good reason to do so. They take extra power, and if they're not PoE themselves they take extra electrical outlets, and then you have the possibility of inadvertently creating a loop when you're working in a confined space, and causing problems.
I'd rather have a direct run back to the switch. It's different if one is traversing buildings, but in a house it's not an issue most of the time.
Pretty much. I deal with this for a living; it's about $150 for a drop, but less expensive by far when pulling multiples through the same pathway. Only major consideration are the size of the penetrations, Cat6a is already double-diameter from Cat5e/Cat6, so pulling six cables through a 2x4 top plate in a wall can be difficult when not wanting to take out too much material.
As I said in another post, two per room, then at least two, maybe three to each entertainment center, one to the center of the ceiling on each floor in each building for WAPs, and more to wherever my office would be.
I wouldn't do fiber unless the house were a new-build, and even then I'd probably install all of the pathways and not actually pull the fiber until it's needed. Normally 6-strand fiber is the standard, which will use three positions on a normal single-gang faceplate when using LC connectors. If you were to put in fiber with the future in mind you'd probably want to go with OM4 multimode 50um, so that you could run 40G over short distance, and you'll spend a lot of money on patch cords and fiber transceivers, and you can probably do 40G over short distance Cat6a anyway.
A 1000' box of Cat6a is about $250. The max-length a drop can be is basically 300', and the average length in a house will probably be less than 100'. That means that $500 will provide 20 drops in a house. That is probably good for both right now and future expansion, but even if one needs more, it's a worthy purchase if one wants to future-proof for something this paradigm-shifting.
...first define where your telecom enclosure or closet will be. Then consider how you want to connect your devices; copper Ethernet, wireless, etc. Then you need to investigate pathways for adding horizontal cables ("drops") to those areas, and you need to look into the equipment side (separate firewall, managed switch, etc) and how you want to define the usage policies.
In my case, if I were in your shoes, I'd install a telecom closet where the old flue for the now-gone basement wood-burning-stove pipes through the ground floor. I'd run two copper Cat6a drops to most rooms, and I'd cable to the entertainment centers at least two, possibly three. To my office I'd pull six. I'd put at least one to ceiling locations in the basement, the ground floor, and the detached workshop, probably digging a trench for a 2" conduit, transition from general-purpose indoor cable to OSP cable when I go outside and back in. I might also put in lightning arrestors that are PoE capable to protect the switch from the WAP or cable being struck; wouldn't worry about protecting the WAP, it'll die if struck regardless.
I'd probably look at a Cisco 3560G 8port PoE switch, it technically has ten ports, eight PoE capable, two not (that can accept fiber SFP transceivers) and there should be at least some L3 capability. Then get a vlan-trunk-capable L3 router/firewall device, put the WAPs on a separate VLAN (and go with VLAN-capable WAPs, for trusted/owned and untrusted/visitor devices) and build rules for the various VLANs, ie trusted can get to LAN devices, untrusted can't.
I'm sorry, I do not trust the benevolence of corporations. As to even the poorest being able to afford the products that corporations offer, I disagree with that concept as I've seen first-hand people neglecting their needs in order to pay for their wants. I've seen acquaintances fail to pay their rent on-time because they spent the money on a high-end video card. I've seen people with cable TV subscriptions and Netflix and smart phones fail to pay their gas bill and have it shut off.
People don't make the best decisions on their own behalf. They make decisions that they feel will benefit them. As to corporations making things cheaper, often that's a byproduct of the amortization of development costs being finally paid, so continued units have less costs to recuperate. It's also common for cheaper items to be decontented to the point that they're really not good, and the customer is screwed-over by giving any amount of money for something that's arguably defective in design. That $35 Indian smartphone for instance.
People buy things from corporations for a large number of reasons. Sometimes that thing has become essential in order to be efficient enough to be profitable, like smartphones can be for people in certain fields. Sometimes peer pressure makes one think that something's essential when it's actually not. The motives are all over the place.
It doesn't hurt the United States that just about every major culture in the world is represented here, and even American-specific culture is very diverse. With some research it wouldn't be difficult to find a community that appeals, even avoiding expensive places to live like New York and San Francisco. And as an American that's travelled fairly extensively in the United States and a little abroad, one can get many of the benefits of going abroad while remaining in one's own country. Boston is very different from Chicago or Hawaii or Miami or Portland. It's easy to move within the country to have an entirely different experience than where one was before, no residency issues or other international-lines problems.
Obviously some other countries have very diverse cultures and regions too; I'd think that India and China could feel much the same way, but there aren't necessarily the kinds of jobs that people look for in those more distinct regions either. That probably helps make America appeal. Don't like the cold? Move to Phoenix or Dallas or San Diego, all different cultures, all one country.
Sometimes movies don't show us technological failings, but human ones. The Minority Report shows us advanced technology (to the point that the UI was praised, and is basically duplicated in shows like Agents of Shield) and shows us human failings.
On the other hand, implementation of technology has become a corporate thing. And as corporations have shown us, they're working in their interests, not ours. They'll release buggy or vulnerable products. They won't patch or fix those problems without being forced to, as such corrections are costs that detract from profit. They'll stand it up and once it's stood-up, if they don't have to have anything to do with it, all the better in their minds.
Unfortunately new things are technology much of the time, and that means that we have to be skeptical. Bear in mind, it's likely that the average readership of Slashdot handles technological and scientific issues better than average, and we still have some doozies of arguments on here. Look at someone that doesn't want to play armchair researcher or enthusiast and see how well they cope. It's not good.
Fuel volume fluctuates with temperature and air pressure though. Knowing the volume of fuel that's flowed through the injectors doesn't necessarily indicate accurately how much fuel remains.
If the fuel sending units were more accurate it'd be a different story, but whether it's four segments, eight segments, a total gallon readout, whatever, if the sender float assembly isn't calibrated perfectly in the tank then it's not going to read accurately on the dash. The most accurate way of measuring fuel is to literally dunk a stick straight down into the top of a tank and read the graduated scale printed on it, like how one uses the dipstick to measure oil fill in an engine. Short of that, knowing the performance characteristics of the system (ie, range) will give one the accuracy that one needs to not run out of fuel.
How about searching for a large briny or brackish inland lake, something actually big enough to offer a degree of freedom to Orcas, and turn them loose there where one can keep an eye on them and provide food? It could either serve as a halfway-house for release into the wild, or could become a permanent home for those that demonstrate that they can't provide for themselves. One could make the venture profitable by having whale-watching tours with glass-bottom surface craft and with submersible craft, and perhaps the animals could actually enjoy some freedom.
It'll never happen. There's too much slop in the gears of a corporate structure to make much stick to the people at the top.
If they couldn't put-away bankers for the pump-n-dump they did that blew apart in late 2007 that spawned global recession, they're certainly not going to do it over what in the grand scheme of things is a relatively minor overbilling.
Comcast didn't fail to disclose a known bug with a product of theirs that has killed numerous people and continues to kill as it remains unpatched though.
The thing is, my car (a 2010 model) still doesn't actually tell me how many gallons are in the tank. I've just got a readout with a dozen or so dots that slowly disappear as they're consumed. Even worse, it's most definitely not a linear chart. I can go close to 200 miles on the top half of the readout, but only get 150, tops, on the bottom half, and even with consistent, level, highway driving I'll see some dots last for 50 miles and then the next dot down last for maybe 20.
That's what a trip odometer can be used for.
I know in city/mixed driving I refuel around 300 miles driven on a tank. I probably could push it to closer to 350, but I'd rather not risk running out of fuel. On the highway I can easily push 350 or higher, depending on how much uphill, how 'spirited' my driving is.
I don't rely on my gauge, and I wouldn't rely solely on a system to tell me how much fuel remains, as those are often not terribly accurate anyway. I rely on knowing the characteristics of the vehicle, and short of Alaska there isn't anywhere in the United States that's more than 150 miles by highway from a source of fuel.

Solid, or slump-block? I've fished high-voltage through slump-block before. It's not exactly fun, but it's not impossible either.
Most residential has a 2x2 fur-strip attached to the concrete wall, with sheetrock attached to that. One can fish the cable in that space.
And there's always raceway from companies like Panduit if one can't fish...
Estimate at $150/cable to pay for installation.
The little "eight port" switches are fanless and quiet. I've got two of 'em sitting on my desk right now; the laptop is louder.
To paraphrase Yoda, "And that... is why you fail."

Chimpanzees will eventually die of their own natural causes. They end, and their effects on the world will end.
True, there are other solutions beyond Catalyst; they're what I'm used to dealing with these days.
I wouldn't even mind some of the older full-gig switches; the 2960S can be had used for a decent price sometimes.
