Attending a convention in the new Boston Convention and Exhibition Center (BCEC) I found one thing very surprising. The show organizer had to install wireless APs all around the building on poles, with long wires leading to power and ethernet. How can a new convention center not already be set up for wireless? I will admit, in some ways it is correct to anticipate that the radios that would do the work will be quickly obsolete, and thus should not be so permanently installed, but it seems crazy to me that a new CC would not have been built with spaces in the ceilings or upper walls ready for some sort of wireless network.
The meeting room halls also don’t have tons of power jacks in the floors. Today, at modern conventions, everybody brings laptops and they want to plug them in. Better conventions in older halls run extension cords and power strips, and there are a few of those here, but why should a new convention center not be ready to go?

Here at the VON conference, there’s lots of talk about numbering. While SIP had a dream of calling people using an E-mail address, the market has delivered devices with numeric keypads only, particularly in the mobile space. So nobody uses SIP URLs or domain names of any kind, and everybody worries about mapping to and from numbers. (Another thing Skype mostly ignored.) The regulators try to regulate VoIP by claiming they have the power when it makes calls to and from the legacy PSTN with its numbers.
But here’s something I learned putting out my free phone at Burning Man. Most of the people said, “I don’t know any of my friends’ numbers!” They did not have their cell phones or PDAs on them. The new generation of phone users is treating numbers as a one-time thing, to enter into the speed dial and forget. They know their own number, and perhaps a few other people, as well as their parents.
However, they do know how to TXT on a numeric keypad. So it makes me wonder, at least for the new generation, if the fuss about numbers is worth anything. What if we did switch back to names or SIP URLs (with short domains) and expected people to use various accelerated typing systems to enter numbers for the first time, and then have the phone remember after that.
One could easily create a service with an 800 number that let people dial it and then use digits to type in a SIP URL or e-mail address and connect to that person when not on their main phone. This is actually better, since even though it’s longer to type, it’s possible to remember it. On VOIP phones and Cell phones and smarter PSTN phones, people would switch to the names or speed dial. And the phone number would die the death it deserves.
More from VON later. VoIP is beyond heating up. As one speaker indicated, it’s past the tipping point. Its dominance over the PSTN is now assured. The only question is when it flips. People say things like, “And when the PSTN dies” here and nobody blinks. Though the regulators, pushed by the legacy lobby, still say things that make me throw my hands up in disgust. I asked Senator Sununu today if Congress had ever looked back and said, “I wish we had protected the legacy systems more?” To be fair, he’s one of the better members of congress on these issues.
Follow-up: Later at the conference, during the concert by Huey Lewis & the News, I thought it would be a nice romantic gesture to call home during his song “The Power of Love.” I suggested that to a friend whose cell phone battery had died and said she could use my phone. “I don’t know my boyfriend’s number. I am not even sure of the area code,” she said. Meanwhile others took cameraphone pictures of the performance and send them along with texted captions in similar romantic gestures. Mr. Lewis even took a cell phone from the audience and sang into it for whoever was on the other end.

Every time I take an RV trip (ie. each Burning Man) I come up with more observations. The biggest one is that it cost $360 in gasoline to go from the bay area to the black rock desert, about 800 miles. And that’s at a price still well below world price. The RV owner said he was planning to get out of the business, people no longer want to pay the gas price.
So why is it taking so long to produce a hybrid RV? Hybrid cars are great of course, but trucks and RVs are what really suck gas and need the improved efficiency. And they have the room for larger and more unusual engine configurations. Most of all, RVs also mostly come with expensive generators and batteries, and a hybrid RV would of course have a super duper power plant and batteries and inverters, presuming the engine was efficient at lower revs. The Hybrid RV’s power plant could also be a backup generator when parked at the non-moving home. Probably make the most sense with diesel fuel, or as I have suggested before, even the highly efficient stirling engine. (Stirlings are big, and take time to warm up, but an RV with batteries is fine with this.)
Every RV’s shower has this hose based showerhead with an on-off dial with a slight leak. Our camp built a much nicer shower using a standard kitchen sprayer. A kitchen sprayer with a lock-on would be much better and would make it easier to conserve water by letting you pulse water where you need it when rinsing.
Cleaning the RV, especially when back from the desert, is hard. RV renters charge fat cleaning deposits and fees. Why doesn’t some company that hires out housekeepers do an RV service. You could come to them. Drive in, and a team of 5 attacks your RV, cleaning it in minutes. Do it at a car wash to also handle the outside if needed. Espcially after Burning Man there’s a business here.
I’ve said these before: Paper towel racks, built-in soap dispensers, inverters, flourescent lights. Why aren’t these everywhere in the RV world, instead of being rare?
Stabilizers jacks are great, but how about something simpler, some way to lock the springs or shocks (of course with an interlock to prevent starting the vehicle!) And while slide-outs are great, why do we never see flip out beds the way pop-top campers have, or a pop-up on the cab-over bed? (Most RVs don’t have any spare wall space except in the master bedroom, which does limit the flip-out bed concept. You also almost never see murphy beds.) Flip-out beds don’t take away your dinette or couch as do the extra beds commonly found. And how about a seat belt design for use on the beds for safe sleeping while driving? You can do this now but it doesn’t seem super safe.

If you noticed a long break in the blogging, it’s because I was at Burning Man. And while people do blog from Burning Man, it’s not what you want to spend your time doing. I will have more entries in the future, but let me relate some stories of the network and the phone booth first.
Last year, we erected a free phone booth in the desert to great results. This year, it was going to be even better because of a plan for a new internet connection. In the past, John Gilmore had brought his satellite dish, which had all the latency and bandwidth limits of satellite. This year he splurged on getting a microwave link in, which will be even faster next year. Sadly, much of that money was wasted because we never got the “first mile” — the on-playa 802.11 network — operating at a satisfactory level. There was huge packet loss and jitter in most places, when it was up at all. Next time some of the money will go into better equipment and planning for the local network.
As such, the phone booth, located in our camp on 7:30, only worked intermittently and rarely with great voice quality. We eventually decided to sacrifice the aesthetic purity of a booth sitting in the desert, connected to nothing, and moved it on its wagon by trike to the center camp, home of the incoming microwave link. The we set it up on the street, with an ethernet wire snaking in. We were no longer wireless, but the voice quality was top notch. I wasn’t able to spend much time with it but reports were that the line got very long at times.
In our own camp, you could tell if it was working or not based on whether there was a line. Even waiting for it to work was better than the 2-3 hour time investment of taking the bus to the phone booth in Gerlach.
Last year, I recounted the emotional experience people had using an unexpected and impossible phone to hear the voices of loved ones. This year, this was magnified by Katrina. I learned of Katrina, in fact, when people came to ask to use the phone to contact their relatives in NOLA. (Read on…) read more »

You are probably familiar with Google adsense, which is providing the ads you see on the right hand side of this page. Adsense code examines the text of pages, and tries to match Google adwords bids against it. The publisher of the page gets some undisclosed share of the Google revenue.
Recently adsense has been improving a lot for me, and my revenue from it per day has more than doubled, either due to better ad placement, better share or higher bids — it’s hard to say. It has gotten good enough that one can now readily see making a living as a good web writer through adsense. At an extreme example, my Copyright Myths article, which is admittedly very popular, is now generating over $250 per month in revenue. Just that one article. An author able to generate articles that popular (admittedly difficult, part of the popularity comes from having been around for decades and being linked to from many places) could make a living wage.
On one hand, Adsense seems like a great implementation of the wall that is supposed to exist between advertising and editorial. I have no idea what ads will appear, I don’t control it. I have no relationship with the advertisers, and there are so many advertisers that it would be hard for any one of them to hold sway over me as a writer.
However, there is an opposite factor. Clearly some topics are much more lucrative than others. My jokes and photos pay just a small fraction of what writing on copyright pays, because there are lots of copyright lawyers willing to bid high to advertise to people curious about that topic. My spam essays pay decently because of anti-spam companies. My DNS essays get little traffic, but when they do they get people selling domain names etc.
In the extreme, if you become the big expert on a disease like mesothelioma, the asbestos caused disorder, laywers hoping to sign up clients will pay many dollars for every click. (It was famously the most expensive word in a survey last year.)
So there is a strong push now, for a writer wanting to make a living (instead of one like me getting some extra change) to write about the very specific topics that get high adwords or overture bids.
Part of this is nothing new. In the past the way to make the most profitable magazine was to cover a topic that would attract readers that advertisers want to reach. Some general media, like newspapers, sought only to gain an audience, and advertisers would pay to reach the general audience.
But advertisers don’t want to reach a general audience, or only rarely do they wish to do so. Google has broken one of the great aphorisms of advertising, “90% of all advertising is wasted, the problem is figuring which 90%.” And from this they have a multi-billion dollar business. But how will this affect editorial down the road?

A mantra in the security community, at least among some, has been that crypto that isn’t really strong is worse than having no crypto at all. The feeling is that a false sense of security can be worse than having no security as long as you know you have none. The bad examples include of course truly weak systems (like 40 bit SSL and even DES), systems that appear strong but have not been independently verified, and perhaps the greatest villian, “security through obscurity” where the details of the security are kept secret — and thus unverified by 3rd parties — in a hope that might make them safer from attack.
On the surface, all of these arguments are valid. From a cryptographer’s standpoint, since we know how to design good cryptography, why would we use anything less?
However, the problem is more complex than that, for it is not simply a problem of cryptography, but of business models, user interface and deployment. I fear that the attitude of “do it perfectly or not at all” has left the public with “not at all” far more than it should have.
An interesting illustration of the conflict is Skype. Skype encrypts all its calls as a matter of course. The user is unaware it’s even happening, and does nothing to turn it on. It just works. However, Skype is proprietary. They have not allowed independent parties to study the quality of their encryption. They advertise they use AES-256, which is a well trusted cypher, but they haven’t let people see if they’ve made mistakes in how they set it up.
This has caused criticism from the security community. And again, there is nothing wrong with the criticism in an academic sense. It certainly would be better if Skype laid bare their protocol and let people verify it. You could trust it more. Read on… read more »

Just back from a day at Bar Camp which was quickly put together as a tongue-in-cheek response to Tim O’Reilly’s Foo Camp and folks who had not been invited. Foo Camp is great fun, and Tim does it all for free, so it’s not suprising he has to turn people away — even me :-) — but Bar Camp was surprisingly good for something thrown together at the last minute with no costs.
It makes you wonder why some conferences have to cost so much. In Foo Camp, Tim provides his campus of course, which he already owns, and some rental facilities and most expensively, food, and lets people come free. Programming is ad-hoc, in recognition that at so many conferences, people come not because of the program but because of their fellow attendees. I haven’t asked Tim what it costs him per attendee but I suspect it’s much more modest than the fees at comparable conferences. People literally camp in empty cubicles and offices, though those not up for that can get hotel rooms or bring RVs.
Bar camp was even cheaper. Socialtext provided the office space in downtown Palo Alto. In just a short time, sponsors such as Technoratti and others provided all the food people could want, and attendees brought snacks and drinks. Fewer folks camped because it was in Silicon Valley, but some of the younger set did. Talks were quickly put together, but interesting, and covered whole ranges of new and interesting software developments. And as at Foo Camp and everywhere else, hallway conversation was the real action.
With the glut of office space in this valley, and in other places, such ad-hoc conferences should not be hard to set up. Nor should sponsors be hard to find for modest food and other needs. If people become interested in having a conference rather than a business, they can do for nothing what could cost $1000 per person and with less work.
Not that I wouldn’t enjoy going back to Foo Camp, but Bar was its own rewarding experience too.

I’ve called before for a system of Universal DC Power and I still want it, but there is a partial step we could take.
I have a laptop power supply that comes with a variety of tips. The tips tell (through something as simple as a resistor) the power supply how much voltage and current to supply for the laptop they are designed for. I bought mine for use in an airplane, others are sold that do both 12v and AC power.
I would like to see one designed for the corporate market, rather than the carry-around market. Ones to be left in offices and under conference tables, so that when somebody visits with a laptop, they can plug it in. No need to get out their own supply or eventually no need to bring it.
Unlike the carry-around where you pick your tip and leave the rest, this would have an array of tips, possibly rotating on a click-wheel, or all connected to a switch where one can dial the voltage/polarity/etc.
Some companies take more drastic steps. At Google for example, I notice they have standardized on thinkpads, and so all desks and conference tables have think pad supplies. Everybody is able to roam the building and be sure of laptop power. These supplies, while a bit more expensive, could solve the same problem.
An alternate would be to standardize the special tip that describes the power needed. Everybody could get a tip or pigtail for their laptop and carry just that around. Conference rooms could in fact have single supplies that let you plug in several of the pigtail. Of course that is halfway to my original proposal.
Now it turns out a considerable majority of laptops take either 16 volts or 19 volts. The main rebel is Dell, which uses funny plugs and often over 20v. Some need more current than others, I don’t know if any need current limiting or if simply making the PS capable of 100w would do the trick. Anyway, in this case, we could develop a standard 16v plug (the thinkpad one) and a different standard 19v plug (probably an HP one), in two different shapes and colours, and people with laptops could carry a cheap converter to plug their laptop into it. Over time, laptops might come directly able to use this, if they aren’t already — on our path to a smarter power bus. Then people could say, “Oh, you have the orange plug. Great, I can plug my laptop into that.” Vendors who make laptops that won’t plug into one of these two will probably think about switching.

Hot in the blogosphere these days, as a result of the Creationism/ID vs. Evolution debate is Pastafarianism, the worship of the Giant Flying Spaghetti Monster. The idea is to show that something as made up as the GFSM is as consistent as ID.
Now as I’ve written before, I think we should teach creationism and ID in the schools as an example of bad science. All students should learn how to identify when bad science and bad math (in particular bad stats) are being used to lie to them. They should take exams where they are given examples of bad science and must spot the flaws to pass.
However, never one to pass up a joke religion, I still think the Pastafari go too far. I propose Monolithism. (Perhaps monolitheism?).
Monolithism is a variation of Intelligent Design which proposes that man was given the gift of intelligent thought by giant black alien monoliths. They came to Earth long ago and are waiting out there for us to show them the results.
Now Monolithism has great visual aids already to show the process. It meets many of the requirements of I.D. except that most people know it’s a movie.

One of the scourages of urban areas is the requirement (I presume) that heavy equipment make a loud beeping noise when it’s backing up. It’s meant to warn anybody standing behind the vehicle, presumably because the driver doesn’t have the same field of vision to see you, and because people are more wary of standing in front of a moving vehicle than behind it.
As such, as we all know, the sound is really piercing. And more to the point, it travels, often for miles. It’s a major noise pollution anywhere near any work site. I presume part of the problem as well is workers wearing hearing protection need it even louder.
So my challege is, can we do a better job? Can we make an attention getting sound that is more directional (aimed backwards, and perhaps down from the top of the vehicle) so it won’t travel as far or distract people not behind the machine?
Can we standardize rear-view cameras, which are so cheap now, so that the operator’s view of what’s behind is top notch?
Can we combine a quieter sound with really bright, moving lights, the kind you would see on the ground if your back were to the beeping machine? Could we blow air with high pressure streams or those long-distance vortexes like the AirZooka makes, or would this be too much of a problem with dust (or in wind?)
Can we have object detectors that spot objects in to the rear of the machine and make the beeps louder when there is something? (Admittedly they are going to go off for a wall or wheelbarrow as much as a guy, and they have to be really reliable because people would start depending on them to know how much caution to use.) Perhaps they can detect that everything they have seen has left the area and reduce the beeping, because if there is one person behind the truck, that assures you somebody is watching and will move anybody who doesn’t see the lights or hear the beeping.
I solicit other ideas to safely warn people about moving equipment that don’t ruin the peace.
Update: I received information from a firm called Brigade which claims to have an answer. They use white-noise alarms. They claim they are easier for us to echolocate than less natural pure-tone sounds, and I agree that they disperse into the environment more quickly so they won’t travel. The piercing alarm has been chosen in the past as it is un-natural and thus stands out more from background, but that means it travels further. Natural sounds fade from notice more quickly but possibly are just as recognizable close up.

As some will know, I got heavily into the Hugo awards 13 years ago during my efforts at becoming an eBook publisher in the SF field. The Hugo award is voted on by the fans who attend the annual World Science Fiction Convention, or Worldcon, a moderately small voting pool (under 1000 of the typical 4000 to 7000 attendees will vote.)
The most important award and 2nd most voted on is the one for best Novel. The least important, but most voted on award is the one for best movie.
But still, for a long time, though both SF and Fantasy qualified for the award, the best Novel went exclusively to Science Fiction (with one dab into alternate history by Phillip K. Dick) and usually to hard, ideas-based SF. This went on until 2000 when the superb hard-SF novel “A Deepness in the Sky” won. The drama award was also heavily into SF, though it had some deviations, such as the coverage of Apollo XI and a few films in the 80s.
But in 2001, for the first time, a Fantasy novel won the best novel Hugo. Not just any fantasy novel, but a children’s novel, Harry Potter 4. Of course, the Harry Potter series is the most remarkable success not just in fantasy, but in publishing, so this is not too shocking. What’s surprising is that in 2002, 2004 and 2005 a fantasy novel would win best novel. At the same time, fantasies won all the best movie awards and all of the new best TV episode award until 2005.

I recently picked up a surplus battery-powered motor assist for a bicycle, and it's a lot of fun. Due to lower power you have to start peddling to 3mph and then it can run the bike for 10 miles at 10mph (for normal weight people, not me.)
All-electric cars didn't do well in the market in part because people were scared of their limited range, slow charging and and high cost, and the annoyance of plugging them in. They love hybrids because they don't have the range problem. Some folks are promoting plug-in hybrids, which are hybrids with lots of batteries. You can and should charge them from the grid, but you don't have to, so your range is the same as a gas car (or better) and on most trips you are much more efficient.
But perhaps cars are the wrong target. Electric bikes are heavy and a little more unstable when slow or being walked, and get really bad if you put enough batteries on them to go 20 or 30 miles. But trikes on the other hand are stable and you can load a lot more batteries onto them for serious range. And electric trikes are wicked efficient, in terms of cost (and fuel burned) per mile of travel. Orders of magnitude ahead of hybrid cars.
And all this is quite cheap to make if done in quantity. If our cities made more bike paths and bike lanes these trikes could become a major commute form, especially in California with its assured good weather. Yes, it's not perfect -- you have to recycle the batteries, and you do have rain to worry about, and the speed is definitely lower. But for shopping trips, neighbourhood trips and short commutes it seems a giant win.

Newspapers won’t like this idea, but the truth is that most of the funnies aren’t funny, certainly not every day. There are some talented people doing comic strips, but it’s hard to do on a 7 days a week schedule, so they are almost all inconsistent.
You can read most of the strips on the web, so the next step is to build a system where we do shared editorial on their quality. People would read the funnies and vote on them. Then, you could present a page which showed you only the ones that made a certain cut. You could tune the cut — “Show me the top 90% of Dilbert, only the top 10% of Blondie” as you like it.
And you could even ask for the top few percent of comics you don’t normally read, though of course some of the jokes only make sense to semi-regular readers, so this won’t always be a winner. But it should be often enough.
Of course, some people have to read the comics before they have been graded. And there are fans willing to do that, but if there aren’t, you can make a trading system that says to make use of the ratings you have to contribute some. (Though if you get too hardnosed about it, people would start to introduce fake ratings to game this.)
User’s ratings would not be absolute, but rather based on their past history, and where in their own spectrum of ratings for that comic a particular rating falls. So it doesn’t help that you rank every Dilbert a 10 out of 10, such scoring would be discarded. Nor can individual comic publishers bump their own ratings on an absolute level, since again it’s a percentile result — they can only promote a personal favourite at the expense of others.
This would not be so hard to code, who wants to code it?

A lot of older computers that people are ready to throw away can be decent linux boxes, in schools or in other charitable locations.
I propose a simple small program (possibly fitting on a floppy as well as CD) which can be inserted into an old computer. It scans the harware and compares it with hardware databases of chipsets, cards and other parts which are known to work well under linux (or your favourite BSD or other OS) and to work well together. It would also evaluate the machine and put it in a “performance class” to describe just how good it is. It might connect to the net (if it can) to download the latest such lists and info and software updates.
The goal is to test if the machine can do a problem-free install, one that asks almost no questions, and converts the system to a nice linux box, ready for some student to run for e-mail, web, and writing. There are so many machines to donate that we can insist on perfection. The program could also tell the owner what upgrades it might need to be good or to reach a performance class. “This machine is good but with 128M of ram it would reach performance class N.” “This machine would be perfect if you swapped the ethernet card for one of these models” and so on.
Next, of course, is a simple distribution, to install from CD-rom or over the network, that can be quickly installed with no questions asked except perhaps time-zone (if it can’t figure that out from the old OS.) The goal is a system that can be run by untrained admins who may never have seen the insides of linux or any other OS.

I’m not the first to think about it, since I see a bunch of patent filings related to it, but how hard would it be to have a sensor for windshield fog. Seems to me you could bounce light (UV perhaps which water scatters, though other colours might work) off the windshield to detect if there’s fog on the inside and use that to control the defogger.
In particular, modern defoggers use the air conditioner which provides dehumidified air when you heat it up again, great for defogging. But also fuel inefficient. I swear that while today’s AC based defoggers are better than the old pure heat ones, I think the AC-off mode of modern defoggers is not as good as the AC-less mode of the old ones.
Anyway, the sensor could at least control if the AC is used, if nothing else.

In this new category, “What a great idea” I will document interesting ideas I have seen in my travels. Things that make you go “why didn’t I think of that?” Some may be new, others just new to me.
At a recent symphony concert, I came out at intermission to see a table laid out with drinks and snacks, each with a little numbered placard. People had placed and prepaid orders before the show, and thus could get their drink without any line.
This made tremendous sense. We have this drink station that gets used for just 15 minutes a night which is terribly inefficient, and they found a way to spread out the work. This fits into one of my major themes these days, “Why should we ever have to wait in line?”
Of course, such an idea may only work with affluent symphony-goers, who are far less likely to try and steal somebody else’s drink order. You could have claim checks and that would still be faster than ordering, pouring and paying, if you didn’t trust the patrons. And, if they didn’t want you to turn off your cell phone during the show, you could even have people TXT in their orders (with keypress beep turned off of course.)
Texting in orders might make more sense in places like ballparks and amusement parks, with a message back when it’s ready. Why miss the game to stand in line for a hot dog?

Recently, Joel on Software wrote an essay on good programmers and how they are qualitatively different from average ones. This is not a new realization, and he knows it and references sources like "The Mythical Man Month." It was accepted wisdom decades ago that a small team of really brilliant programmers would make a better product than a giant team of lesser ones.
That wisdom, however, failed to predict the rise of Microsoft. That wisdom says a software monopoly is impossible because there are reverse economies of scale in software development. So how did Microsoft do it. The answer to that is perhaps the true genius of Bill Gates.
The trick, in part, was finding ways to make software tremendously broad in scope and features. Microsoft Word has bazillions of features, as most people know. Windows in its kernel isn't much more complex than other systems but the real Windows also includes a vast collection of DLLs (libraries) that seem external but are really part of the OS. To clone the OS you must make these DLLs -- and many other things.
A program like MS Word, with so many features, takes raw money to clone. You need that core team of great programmers -- and Microsoft has many great programmers, make no mistake -- but you also need a giant team of lesser ones to keep all the features going, to QA and document them, to translate them and make them work in so many environments.
This does have an economy of scale in the development. Combine that with the immense economies of scale that exist in the distribution of all soft things that can be copied for free, and this permitted a monopoly.
Of course, no single user makes use of all the features of MS Word, so it took even more skill to get them to demand such a complex program, when they might be better served by a leaner, more elegant system. Like I said, this is only part of it.

Mapping programs, and fancy GPSs come with map databases that will, among other things, plot routes for you and estimate the time to travel them. That’s great, but they are often wrong in a number of ways. Sometimes the streets are wrong (missing, really just a trail, etc.) and they just do a rough estimation of travel time.
Yet all the information is there, being collected constantly by every car that drives the roads with a GPS. Aggregating this data will tell you what roads are real, what roads might be missing, which are one-way, where freeway entrances and exists really are.
And it will also tell you real-world speed examples at various times and dates, at rush hour or otherwise. Even a range of speeds so you can know the speeds for faster and slower drivers and get a really good estimate of your own likely speed on a given road at a given time. After removing the anomalies (like people stopping for coffee) of course.
Rental cars with GPSs are collecting this all the time (sometimes to nefarious uses, like charging whopping fees for brief trips out of state). Technically this data can be had.
But here’s the bad part — there is a potential for giant privacy troubles unless this is done very well, and some may be impossible to do without a privacy risk. After all, until you upload the data, there is clearly a log of your travels sitting there to be used against you. Only a system with rapid upload (and which discards data that gets old, even if it’s not uploaded) would not create a large risk of something coming back to haunt you.
The data would have to be anonymized, of course, and that’s harder than it sounds. After all, your GPS logs say a lot about you even without your name. Most would identify where you live, though that can be mitigated by breaking them up into anonymized fragments to a degree. Likewise they’ll identify where you work or shop or who you visit, all of which could be traced back to you.
So here’s the Solve This aspect of this problem. Getting good data would be really handy. So how do we do it without creating a surveillance nightmare?
