Oh, don't get me wrong, if Google offered GigE to my house, I'd get it too. It's just overkill. I don't mind overkill at all. I actually play in the land of overkill on a daily basis.:)
I do agree that user needs have increased over the years. They always will. We're a long way from "needing" GigE. Like far enough where they could have deployed with 100Mb/s, and upgraded it to 150Mb/s in 5 years, which would still be overkill.
If I had a choice between Verizon FiOS selling me 100Mb/s and Google selling me 1000Mb/s, but testing throughput and latency showed Verizon FiOS to be faster, I'd stick with it.
Where I am, our choices are Verizon FiOS, Brighthouse cable, and a few rather sad DSL providers. Brighthouse frequently has killer deals. I've used both, in residential and commercial settings. The Brighthouse solutions advertise high speeds, but can't deliver the speed or low latency on a consistent basis.
I had a friend who was a loyal Brighthouse user. She set up a FiOS line to use for a few servers in another room. Because of problems with Brighthouse, we ran an extra network drop from the server room to her office room, so she could switch her default gateway as needed when Brighthouse took a dump. It became often enough where she dropped the Brighthouse line. Sadly, it was a good way for her to test what outside users saw.
Most of it is a last mile problem. Brighthouse oversells their last mile. Verizon doesn't. We won't even discuss the DSL providers, since they're just providing legacy services on antique technology.
Pay attention to the notation. I said 400Mb/s, not 400MB/s.
400Mb/s = 50MB/s. 1000Mb/s = 125MB/s.
Most people measure bandwidth in Mb/s. I suspect it's to throw off people who try to relate disk usage to throughput. We also measure the total throughput, not packet payload, which has a whole set of headaches with it.
Well.. I have a 75/35 line, and I measure throughput at my firewall. Looking across today, most (like 99%) was below 10Mb/s. There were a few spikes, not nothing really amazing.
I've monitored offices with 30 to 50 users, and a 100Mb/s link was overkill for them.
One place I worked, they were perfectly satisfied with 300Mb/s for 3,000+ users. It was a quiet secret that the desks were locked down to 5Mb/s, and people still watched YouTube and Netflix from their desks. I won't say it was 3,000 users all watching movies at the same time, but with an organization full of overpaid underworked employees, I'm sure they probably viewed every cat video on the Internet at least 20 times a week.
People *love* to overestimate their need, and misguess their utilization constantly. Most people don't monitor and graph their utilization, so they honestly don't know if they need 1Mb/s or 100Mb/s. When the ad says "You can watch streaming HD movies, if you upgrade to xxx", they'll do it. End users are suckers.
Peering is *always* an issue. Some companies do it well. Some do not.
At this point, no one has said who the carrier really is. It could be Google. It could be a locally source carrier. A few traceroutes would at have given us a hint.
I brought up quite a few fresh GigE circuits in datacenters. For the first day or so, it was exclusively mine to use. Once I got bandwidth monitoring up, I got to see what the line could really do.
With plenty of sites, I couldn't pull more than 1Mb/s. Your throughput is still totally dependent on the throughput of every point from their disk to you.
My laptop couldn't saturate a GigE line. The same as the previous statement applies. If the laptop won't pass 1000Mb/s for any portion, you won't get the full speed. It could be the bus, disk, or just the software handling the connection.
To saturate the line, I'd bring up a few idle servers, and then have multiple large downloads going to multiple places. Like, downloading distro ISOs from various mirrors.
Sometimes the equipment you have in between is the bottleneck. I put GigE in at my house, because I have servers and my home LAN. The consumer router for the home LAN I was using did GigE on all ports. I couldn't pull more than 80Mb/s through it. I swapped it for a slightly better consumer router, which will pass about 400Mb/s.
Even with 400Mb/s between the two rooms, I can see the throughput suffer if a server is overloaded, or is doing something dumb.
Watching my uplink graphs, I see that I very occasionally pull 80Mb/s from the Internet. Actually last night was 85.3Mb/s. They are tiny spikes when intensive traffic hits. I believe, because of when it happens, that's a backup event from a remote site. Normal daily use is single digit Mb/s. Like, someone on the LAN as I'm writing this is playing a FPS online. Their latency is in the single digits. They're pulling a whopping 220Kb/s.
I guess if you had 5 or 6 torrent boxes running, you could saturate your GigE line. Normal use, most people won't be able to tell the difference between a 10Mb/s uplink and a 100Mb/s uplink.
How many commercial companies would have this much customer data at risk?
You won't like this answer. An awful lot of them, and most of them you've never heard of. There is an entire industry revolving around background checks and investigative resources.
I've personally worked with some of these companies, so I have first hand knowledge, not just rumors. We literally had all the PII on 99% of the US population, age 18 and up.
Any company that has any worthwhile information has "credit headers". Basically, name (first/last/middle), SSN, DOB, and a list of addresses and phone numbers.
Depending on the company, they can have more. Some aggregate information from surveys. Some associate people who have lived at the same address as potential relatives. Some provide details on you, your family (frequently guessed), and even neighbors.
Some have information on your shopping habits. Some get them from surveys. Others directly from places like Walmart/Target/K-mart. Others from branded credit cards. And plenty of information is gathered from store loyalty cards.
Some information is gathered directly from credit card processors. So Visa, or your bank don't hand off that information. That doesn't mean the 3rd parties you'll never know about don't collect and aggregate the information.
A lot of the information out there wasn't legally gathered. For example, if I got a sysadmin at say Verizon Wireless to dump their database of users, with name, address, cell phone, I could pay him say $20K for it. It would be worth it, since I'd make more than that selling the information by individual search. I could also resell the list as much as I want for $20K+ each.
Companies buy and sell these lists all the time.
Some companies sell totally bogus lists. I used myself and aliases I've used to validate their data. I've seen my alias show up with other information I've never used.
Some companies sell the data as "new" or "fresh", while it's ancient. One had car registrations, and "my" newest vehicle I hadn't owned for over 10 years, but failed to have any of my current vehicles.
There's nothing illegal about it either. Mostly they're breaches of contract. If you're using a database that I bought, you aren't licensed for it. There are frequently seeded entries. By themselves, they look normal. Like, I may add a fake record, John Wayne Smythe at 14 Main St, SSN 135-63-2399 (just random numbers), so if I run a search against their database and see it, I know it's stolen.
Lots of information out there was gleaned from government web interfaces, before they started restricting PII, including DOB and SSN. Unfortunately, those pieces rarely change, so John Wayne Smythe's DOB and SSN will be the same until he finally ends up on the SSA Death Index. Some conveniently ignore that index too, so they may be stuffed full of real people who are already dead. Sometimes that's useful. If you're searching for JW Smythe, and find out that he died in 1996, any current activity is a fraudulent identity.
Working in that industry, I've learned that I love aliases, and use them everywhere. There's no reason that I should use my real name here, it's just another forum. The same with every forum I visit.
Nah, they "big dogs" as you say, have already expressed a disinterest in providing to those homes.
Setting up an ISP of some sort would be fairly easy. From the main building to the cliekts, it could be wireless with decent directional antennas, overhead fiber, underground fiber, or (forgive the thought) copper. A lot of it depends on the topology, and what is allowed. I've done overhead fiber, and directional wireless at different places, depending on what problems were between point A & B..Z.
I already have a business line that I could resell as much as I want. The local carriers, including my uplink, don't care what I do with it (within reason). I could resell to every house in my neighborhood. The average consumer doesn't suck up much bandwidth. They only buy the huge pipes because they think they're better.
.50 BMG is preferred for parades. While more expensive, it will save in the long run. That, and you won't risk being trampled by spectators running away.
LEDs are getting a lot better and more cost effective. I wanted to switch to them years ago, but at the time (as I recall), they were about $30/ea, and the light output was more like a 15w incandescent than a 40w or 60w that we desired.
Now we can get them much cheaper, with the appropriate light output, so we've been using them when an incandescent burns out. The 40w or 60w equivalent are actually equivalent.
You can find ones that meet your particular need.
Not all that long ago, people were complaining about the color output of fluorescent tubes. I did a little research, and strangely enough some pot growers clued me in to the "right" combination. A "soft white" and "cool white" tube in the same 2 tube fixture makes a lovely full spectrum of light. They were the small scale pot growers, who didn't want to use the high pressure lights. Like 4 or 5 plants, versus 1,000 plants.
An ex-girlfriend of mine was growing flowers and cooking herbs (really). It was too hot outside, and plants were dying. We moved them inside under the fluorescent combination, and they thrived, and it didn't kill my power bill.
You can find the same with LED lighting. Some are obvious about their method, where you can see the individual color LEDs, combined to make a perfect full spectrum light. Some may be marketing fluff claiming "full spectrum". Worst case, make your own. It's a lot easier to make your own LEDs, than it would be to make your own fluorescent tubes.
You and I between us have almost assuredly done more real work on the Triton
I think we've given the whole thing a lot more thought than it was worth.:)
No problem on the gases list. I was curious, that's why I bothered to search it. I had lots of "what if.." and "what about.." on my mind. I knew there should be other gases present. I'm glad I found decent information on it to share.
Ya, his mystery power source would revolutionize the world. Like, cell phones that can run for years on a single charge.
I've only done a bit of diving myself, and it was close enough to the surface that I didn't need anything more exotic than a tank. I've luckily (I guess) never used a rebreather. I'll take your word on the excitement of using it.:) Passout games are dangerous in the comfort of your own living room surrounded by pillows. I'm thinking underwater is less than ideal.
If the Triton thing ever works out, it'll revolutionize all kinds of technology. It made for some cool pictures though.
The Like-a-fish has a mention of doing something with the DoD, but they couldn't discuss it further. I've seen claims like that in the past from really cool "could maybe work" places, that really turn out to be "We got our 15 minutes of fame! Whoo!"
Just looking at the design, other than saying "micro" a few times like waving a magic unobtanium wand, they made the impossible into a photoshopped picture.
It's a neat idea, and does have some scientific basis, but it leaves an awful lot to the imagination of the person who made the photos. I guess that's the fun of concept science. Maybe someday someone will make it real.
I did a little searching, and found "Like-A-Fish", which does appear to have something. The wiki page has more details. It requires a 1Kg battery, which lasts for one hour.
The Wayback machine (archive.org) is nice and all, but it doesn't guarantee longevity. Empires come and go, and things are lost to time. If archive.org loses it's funding, it could simply go away. It may be politically advantageous for such archives to disappear. Plenty of times in history, there has been mass destruction of records.
My mom is running into this following our family genealogy. Most family records for one line farther back than the mid 1400s are gone. A wealth of information has been lost over the years. Plenty of books are now amazingly rare, or no longer exist.
All we can hope for, for the longevity of information, is for it to be kept in multiple places, in reliable formats. For plenty of documents, a printed copy in a box in someone's house may be the only surviving copy in 100 years.
I agree. Part of it falls back to the archiving problem. How do you store your data for long-term recovery? Technology changes rapidly. If you had data stored on media from 30 years ago, you'd be wondering where to find a working reel to reel tape reader or floppy disk drive. Digital media degrades. All disks have a finite shelf-life. For giggles, when I still had a floppy drive laying around, I tried to copy an old version of Unixware. It was brand new still sealed box, that was always kept in a climate controlled office. I got a few files from one disk, and that was it. You also run into the problem of being able to read a particular format, and the accuracy of the scans.
Sure, you run into the same problems with paper. The media can be damaged. The language may (and likely will) fall out of use. That's a problem over centuries, instead of decades.
It's lovely to have digitized copies of stuff now, but it's never an excuse to trash the original media. It can (and will) lead to loss of collected information. In another 100 years, we're going to have a huge gap, where electronic data is lost, and there is no paper copy to fall back to. Like, in 100 years, no one will ever find this post to say "yes, he was correct".
Crime maps are available for many cities. Unfortunately, there was a lot of noise made a while back about decreased property values and business losses when crime stats were going to be included in driving directions.
Google Maps and my Garmin can route my around traffic, but they sometimes insist I drive into bad neighborhoods. That's fine in the greater metro area that I live in, since I know how dangerous various areas are. It's not so good when I'm in a strange town.
I was out of town for work, and told the people at the site where the maps had me drive through. They asked how many times I was shot at. Apparently they weren't the safest neighborhoods. Fortunately, the locals, while dangerous, couldn't hit a moving vehicle.
The shooter is 71 years old. "The rest of his life" isn't really a long time. 1 year in jail could be a life sentence. That is assuming he lives long enough to go through a trial.
I'm close to where the shooting was, so it's plastered all over the news here.
No matter how I look at it, I can't make an excuse for the shooter to have been justified. He had every opportunity to do something else. Move seats. Get a manager to resolve it. Say "fuck it", leave, get a refund and go home. Just accept the fact that there are others in the theater, and one is bound to annoy you in some way.
If your testimony is "I've never held a gun", then a photo you posted of yourself with a gun is then evidence, showing that you lied. It's very easy for a judge or jury to assume one lie means anything you've said can be a lie. And as others have said, perjury.
People have a horrible time trying to comprehend 3 dimensional space. The rubber sheet analogy (obviously) only works in 2 dimensional space. But it does a better job than just saying "well... because."

What was your latency like? You could have GigE, but if it's 1000ms pings, that's going to be worthless for most of this audience.

Google Maps and my Garmin can route my around traffic, but they sometimes insist I drive into bad neighborhoods. That's fine in the greater metro area that I live in, since I know how dangerous various areas are. It's not so good when I'm in a strange town.
I was out of town for work, and told the people at the site where the maps had me drive through. They asked how many times I was shot at. Apparently they weren't the safest neighborhoods. Fortunately, the locals, while dangerous, couldn't hit a moving vehicle.
The shooter is 71 years old. "The rest of his life" isn't really a long time. 1 year in jail could be a life sentence. That is assuming he lives long enough to go through a trial.
I'm close to where the shooting was, so it's plastered all over the news here.
No matter how I look at it, I can't make an excuse for the shooter to have been justified. He had every opportunity to do something else. Move seats. Get a manager to resolve it. Say "fuck it", leave, get a refund and go home. Just accept the fact that there are others in the theater, and one is bound to annoy you in some way.
You can try to make that argument. I doubt it would help at all, unless it had some amazing circumstances behind it.
If your testimony is "I've never held a gun", then a photo you posted of yourself with a gun is then evidence, showing that you lied. It's very easy for a judge or jury to assume one lie means anything you've said can be a lie. And as others have said, perjury.
I thought they finally killed that off last month. Or the other 7K times it was declared dead.
People have a horrible time trying to comprehend 3 dimensional space. The rubber sheet analogy (obviously) only works in 2 dimensional space. But it does a better job than just saying "well ... because."
