I don't think you'll get much for my personal number (the equivalent of the US social security number). Anyone, including you, can call the tax office at +46 8 564 851 60 and get it for free.

Profiting off a secret password is not intrinsically illegal.

The journalists David Leigh and Luke Harding famously made the WikiLeaks password "SplinterItIntoAThousandPiecesAndScatterItIntoTheWinds" public when they included it in a book. https://en.wikipedia.org/wiki/WikiLeaks:_Inside_Julian_Assan...

They didn't get special permission to sell that manuscript to the publisher.

Besides, all of my passwords contain secret information concerning Swedish defense installations, making them illegal for you to publish. /wink

Repeating myself, you do not know what aristocracy means.

In late Middle Ages England, I could be a copyhold tenant to the mesne lord, with the copyhold passed on by inheritance to my heir, following the traditional inheritance scheme of the manor.

I do not own the land - the mesne lord does. Yet I have the right to live there, and the right to pass on that right through inheritance.

According to you, that makes me - a copyholder - part of the aristocracy?!

No. That's an absurd re-definition.

You may want the equivalent of new enclosure laws so that complicated traditional land use practices which give a peasant the inheritable right to graze a few sheep in the local commons is replaced by the simple exclusive control of a local lord. That's how lords and capital holders traditionally gain more power and control.

That still doesn't mean it's meaningful to say those peasants were part of the aristocracy.

You grew up in a culture which prioritizes a certain view of land ownership that dates back the feudal system, then over time the local lords gained strong control over the land and government, followed by the imperial era where land possession and exclusive control brought in untold riches. You and I come from an ex-colony of that imperial system, which respected private land and exclusive ownership only when it involved certain people - for others it could be taken by force. "A man's home is his castle" was only valid for rich white men, and those with implied fealty to rich white men (aka "real Americans").

Sweden never had a feudal system, nor (despite being a kingdom) a strong form of aristocracy. Socialism has a much stronger history here than in the US. Its traditions are therefore different. Don't try to interpret it all through what appears to be an understanding of 19th century English aristocracy.

And even if I'm completely wrong, who care? Inheritable land ownership and nepotistic transfer of corporate ownership lead to extreme centralizations of power which cannot be matched by a Swedish rental agreement. The Wallenberg family controls a substantial fraction of the Swedish economy. A first-hand rental contract had limited use of about 80 square meters.

I don't think you understand what aristocracy means, I don't think you understand what the equivalency is supposed to be, and I don't think you understand what rights you have with a first hand contract in Sweden.

I know you don't know what a first hand contract means, because you incorrectly asserted leases let someone "temporarily occupy a residence", when in Sweden it can be for the life of the renter.

Furthermore, while that right can be extended to your wife or children, technically speaking it isn't "inherited" and it isn't simply passed on to your children like a title of nobility would be. You must have lived together for several years, making your home actually your wife/child's home too.

Instead of "inherited" like I wrote, it's more like your landlord is required to recognize that additional resident as a new leaser, even if that name isn't on the original contract.

And unlike aristocracy, as a renter, you have only limited abilities to remodel. You can't decide on your own to convert the living room and dining room into a great room, or to tear down and replace the bathroom. Only the landlord can make that decision.

So, how this is like an aristocracy?

> If you have a piece of property, that is reserved for your exclusive use

That's another way I can tell you are not Swedish.

In the US you can buy up 160 acres, post "no trespassing" signs, and have the government help enforce your exclusive property rights.

In Sweden, that prohibition is illegal - most of your land (except that closest to your home) is not for your exclusive use. Others have the right of public access, and trying to enforce exclusivity would considered distasteful, if not immoral.

> very same thing about property owners who

You may not like the obligations under the Treaty of Guadalupe Hidalgo, and probably don't like various perpetuity clauses in treaties made with Native American nations, but that doesn't make it meaningful to say those property owners who have perpetual and heritable property tax exemptions are therefore members of an aristocracy.

I do not think you are using the term "aristocracy" correctly.

If you are talking metaphor, the "lord" in "landlord" is a far clearer sign of aristocracy. Capital can be passed down through multiple generations, as the Wallenberg family well knows - now in their fifth generation of ownership.

Up until 2003 the Kingdom of Sweden had an actual aristocracy.

Renters like me were never part of it.

> They hold a lease to temporarily occupy a residence that is the property of someone else. ... it's what's actually happening.

That's not what's actually happening.

In Sweden, a first-hand rental agreement is effectively for life ... actually, even longer as the tenancy be inherited by your spouse and children. The regional rent tribunal can and do override a landlord's decision to terminate the lease.

I cited cellVIEW in a parallel comment. ;)

I still think "few" is the wrong word. I usually think of "few" as meaning up to around 6, while Chimera and VMD can easily handle hundreds of proteins at the atomic level.

Thanks! That's much more like what I expected.

Odd. I can't see why. I think we had 128 MB on that IRIX box, and I know I loaded a 1 million atom structure with copies of 2PLV (full capsid plus a bit more to get to a million.)

Each atom record has ~60 bytes (x, y, z, occupancy, bond list, resid, segid, atom name, plus higher-level structure information about secondary structure, connected fragments, etc.) We had our own display list, so another (x, y, z, r, color-index) per atom, giving 20 more bytes. We probably used a GL/OpenGL display list for the sphere, and immediate mode to render that display list for each point, so all-in-all about 100 bytes per atom, which just barely fits in 128 MB.

That was also all single-threaded, with a ~0.1 Hz frame rate. Again, in the 1990s.

I wanted to see what more recent projects have done. Google Scholar found "cellVIEW: a Tool for Illustrative and Multi-Scale Rendering of Large Biomolecular Datasets" (2017) at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5747374/ which says

> The most widely known visualization softwares are: VMD [HDS96], Chimera [PGH04], Pymol [DeL02], PMV [S99], ePMV [JAG11]. These tools, however, are not designed to render a large number of atoms at interactive frame-rates and with full-atomic details (Van der Walls or CPK spherical representation). Megamol [GKM15] is a state-of-the-art prototyping and visualization framework designed for particle-based data and which currently outperforms any other molecular visualisation software or generic visualization frameworks such VTK/Paraview [SLM04]. The system is able to render up to 100 million atoms at 10 fps on commodity hardware, which represents, in terms of size, a large virus or a small bacterium.

Following that is a section on Related Work:

> With their new improvement they managed to obtain 3.6 fps in full HD resolution for 25 billion atoms on a NVidia GTX 580, while Lindow et al. managed to get around 3 fps for 10 billions atoms in HD resolution on a NVIDIA GTX 285. Le Muzic et al. [LMPSV14], introduced another technique for fast rendering of large particle-based datasets using the GPU rasterization pipeline instead. They were able to render up to 30 billions of atoms at 10 fps in full HD resolution on a NVidia GTX Titan

Checking up on VMD, in "Atomic detail visualization of photosynthetic membranes with GPU-accelerated ray tracing" from 2016:

> VMD has achieved direct-to-HMD rendering rates limited by the HMD display hardware (75 frames per second on Oculus Rift DK2) for moderate complexity scenes containing on the order of one million atoms, with direct lighting and a small number of ambient occlusion lighting samples.

Those citations are 6-7 years ago, which make me scratch my head wondering why ChimeraX can't handle a picornavirus.

Do you know what the author means by "Current visualization software, such as UCSF ChimeraX6 , can only render one or a few protein structures at the atomic level."

I haven't used VMD for about 30 years, but even in the 1990s I was using it to visualize the full poliovirus structure (4 proteins in 2PLV * 60 copies, as I recall).

It took about 6-10 seconds per update on our SGI Onyx, but again, that was 25 years ago.

Yes, I only needed 2D so that's all I did.

I looked at the C code in [0]. It looks like it goes to/from the x,y,z coordinates each time, which certainly works, but is not all that fast, and I was interested in higher performance.

If you haven't read it, take a look at Hacker's Delight, which goes into space-filling curves.

I believe the Perdacher et al. code handles 2D generalized Hilbert curves without a kink, but it doesn't look as nice. That's the code I link to at https://gitlab.cs.univie.ac.at/martinp16cs/mortonlu/-/blob/m... but in the HILLOOP code. You'll also need the .c file next to it.

It's not easy to extract. I've mostly ported it to standalone C. Try http://dalkescientific.com/hilbert8.c . I last touched it last summer and don't recall the status.

What I remember was it wasn't as evenly distributed as the gilbert code, and for my code I wanted to prefer nearness over strict neighborhoods.

For those interested, I have a C implementation of Jakub Červený's Gilbert2D, with Python bindings, at https://hg.sr.ht/~dalke/rectfillcurve, along with a few other rectangle-filling curves.

My wife has a smart phone. I do not. I can say that so far, in Sweden, it's not necessary to have a smart phone, but it is growing harder.

The one time a client required MFA they had me install an app for my laptop + SMS.

The local cab company (I live in a small city) accepts phone calls and has a web interface.

The few times I've visited another city without my wife in the last few years, I used a paper map. Paper maps are getting harder to find.

I can access government services and banking via BankID, which exists as a desktop app. I've also found that some places don't fully support using BankID, over the smart phone version "Mobile BankID". In one case where we had to sign things jointly, I had to log in with BankID then have her confirm with Mobile BankID, because the other way around does not work.

To log into the bank, I have a physical authenticator, and I see the bank staff use a physical authenticator internally for their operations, so I do not think that will be changing soon. I suspect that companies also use a physical authenticator to log in, so that access is gated on easily observable possession rather than on personal or corporate smart phones.

What's getting more difficult is minor money transactions. Many people use "Swish", a mobile payment system and don't carry or use cash, and Swish is also common at smaller businesses. My barber, for instance, got rid of his card terminal in favor of Swish, though he does accept cash. I wonder when I'll have to deal with a "Swish-only / no cash" event.

I can see that parking is increasingly hard to do without a smart phone, as the payment points are being removed in favor of a sign telling people to use the app.

OTOH, my wife is getting annoyed how Google wants her to do 2FA verification. She's logged into several devices, including tablets for the kids. Yesterday the 4 year old wanted help opening the Google Video app, which for some reason wanted 2FA verification saying it was a new device. I could not provide it, but luckily my wife was also home and could deal with it. Still, that situation has clearly gotten a bit worse for us, and there's no solution where our baby sitter could have resolved it were she alone with the kids.

(To make things more annoying, Google was trying to send the verification to an old tablet, which we rarely use because of a cracked screen and nearly zero battery life. She was able to go in via her phone and figure it out instead.)

Scenes from the 1990s:

In 1991 a friend needed to fly home. She was anxious about flying. I went with her to the gate until loading, to help her keep her calm. Not possible now. You could also meet people at the gate when they arrived.

In 1998, working for a startup, my boss came in on a late flight. I volunteered to pick her up. I got to the airport about 15 minutes early. It's late, and not busy. I park right in front of the terminal and wait. While waiting, I cleared up some trash from my car. Now, due to concerns about possible car bombs, the airport prohibits parking in front of the terminal.

In the early 2000s I flew from New Mexico to Sweden pretty regularly. The group I visited had a weekly sauna. I would bring a 6-pack of Modelo, tortilla chips and salsa as my contribution. Not possible now, due to the liquids rule put into place a few years after 9/11.

You say with PreCheck and Global Entry security is easier than before, but in the 1990s it was easy. Luggage in the X-ray machine, walk through metal detector, and done. No pulling out of laptops, liquids, no TSA id check. And I think even that security wasn't done 100% of the time.

There was still an id check at check-in but that was because in th early 1990s the airlines wanted to prohibit the ticket resale market. In the 1980s if you had a New York/LA ticket and couldn't make the flight, you could sell the ticket to anyone else. Even with the id check, a partial match was accepted - my mother and I have the same initial, so either of us could fly with "A. Dalke".

I heard from older people that in the 1980s kids who were plane enthusiasts would go to the terminal just to watch the planes. Back then there was no security check at all.

Each of these are small things, but they add up.

As I recall, he worked at 3D Pharmaceuticals on their ABCD project. The company was then bought by Johnson and Johnson. He later went to Wall Street. My knowledge comes indirectly through Dimitris Agrafiotis, who was the head of that project.

Google Scholar lists several papers with him as co-author, like the ABCD paper at https://pubs.acs.org/doi/pdf/10.1021/ci700267w which has "3DX supports these functions through a highly finessed UI and a superb rendering engine that delivers fast antialiased graphics with subpixel accuracy." citing "Shemanarev, M. The Anti-Grain Geometry Project. http://www.anti- grain.com (accessed June 1, 2006)."

I read the book shortly after moving to New Mexico. It helped provide a depth to my understanding of the state, not just with water issues, but also long-standing cultural differences between the Spanish and Anglo populations (and subdivisions therein), and an awareness of what was part of the cultural context of the late 1960s/early 1970s, like the Coors boycott (see https://en.wikipedia.org/wiki/Coors_strike_and_boycott).

How do you figure?

Why must it be Kowloon Cube and not any form with an intermediate density?

I live in Trollhättan, a Swedish city of about 60,000 people and don't have a car. It isn't hard. And Saabs were built here, so this isn't some sort of anti-car place.

I used to live in Santa Fe, NM a US city of about 70,000 people. I had a car, but across later visits was there for a couple months without a car and found life much harder.

Santa Fe was founded in 1610 so was a city for 300 years before cars became popular. Its population was about 5,000 in 1912, so most of the build-up was during the car era.

Trollhättan became a city in 1916, when the population was only 15,000, so again most of its build-up was during the car era.

Why does transit-oriented development make sense for Trollhättan but not Santa Fe?

When you say "small town", what size do you mean? https://en.wikipedia.org/wiki/Town#United_States says it varies by quite a bit - Alabama says a town has a population of under 2,000, while in Connecticut, West Hartford is a town with a population of 64,083.

Could you gave an example of the urbanists you mean? There isn't much need for public transit if you can walk across town in 15 minutes.

In this part of the kingdom of Sweden, our kids were affected.

They couldn't spend time at the library (max 15 minute visits), they couldn't go to the local science center (closed), they couldn't go to the small farm that the city runs (closed for visitors), and they couldn't go to a visitor center usually open in summer and with the only toilets near a water-themed playground they enjoy.

Ahh. That was the one where it actually does work, if I change the User-Agent.

How curious!

I don't have uMatrix or other ad blocker installed.

I turned off all "Enhanced Tracking Protection" and still see nothing in Firefox.

I don't know what you mean by "by a shitty corporation for shitty ends ... sites that benefit me". It's run by the regional council (https://en.wikipedia.org/wiki/V%C3%A4stra_G%C3%B6taland_Regi...), which is the political organization responsible for the area's public healthcare system. The page lists available COVID vaccination appointments, which benefits me as I was looking to get a booster shot and wanted to know where to go.

Could you describe what "works" means?

On Firefox (I am using the most recent version for macOS) I see only only about a paragraph of text, plus header and sidebar.

In Safari I also see pull-down menus for "Kommun" and "Tidsperiod för bokningsbara tider", plus other input items, and a description like "Antal mottagningar: 23" plus a list of locations.

Sorry for taking so long to reply. I was away on a trip.

When I was there there was essentially no dedicated bike paths. You had to ride on the street, with not even a bike lane. It's a bit better now, with a bike path next to the RailRunner line.

There is a lot of gravel in town, with places where the gravel gets on the side of the road where people park, as when a dirt road or dirt driveway comes onto the road.

In my first few months of living in Santa Fe, I got driving off the road by someone cutting in front of me.

Checking now, it's gotten better. I lived around 601 28 W San Mateo Rd, Santa Fe, NM 87505, USA and worked 309 Johnson St, Santa Fe, NM 87501, USA (the apartments have gone condo, and the company I worked for has long since gone bust).

Nowdays I would be able to take the rail trail to the Railyard, but then either bike with traffic or on the sidewalk the rest of the way.

Or I could bike along some busy streets, like take a bike lane on Galisteo into the center of town.

Neither are that appealing.

I certainly know people did bike there, but that does not mean I felt comfortable doing so, even after 10 years of often using a bike for errands in Tallahassee, FL, Urbana/Champaign, IL, and Mountain View, CA.

The site which lists available COVID vaccination times for this region of Sweden does not work in Firefox but does work in Safari: https://www.vgregion.se/ov/hitta-vaccinationstider-vgr/vacci...

I don't know the reason for the Firefox failure.

The Adobe site https://new.express.adobe.com/tools/generate-qr-code# says it does not work with Firefox, but if I change the User-Agent it does work.

I ran into both in the last month.

Your experience for most of that decade was when Firefox was much more widely used than it is now, so had a higher support priority.

I can name one: a house at Monterey Place, Santa Fe, New Mexico, US

According to Google Maps it's no more than 10 minutes to any edge of the city. It's also near stores and a rail station with service to Albuquerque.

While I lived north-east of there, most places I went to in Santa Fe were within a 10 minute drive of where I lived. I rarely went to the SW corner of town.

I worked from home.

> Has anyone moved from a semi-dense area where just about anything was within a 10 minute drive, to a situation where they didn't use a car and still lived a decent efficient life?

I used to live in Sante Fe, New Mexico in the US. The city was founded in 1610. The city core for the first 300 years was of course walkable, but the last grocery store downtown closed around 2000 so it's a mile walk to the nearest store (biking isn't really an option in Santa Fe).

When I lived there the population was about 65K. I lived in a post-war suburb about a 30 minute walk from the center of town. When built it was on the outskirts of town, connected to downtown via a gravel road. It's all paved now, and a great place to live with a car as just about everything was a 10 minute drive away (though I would need to pay for parking downtown).

The city extends many miles away from the center of town. Going along Cerrillos Road you can see the effect of zoning changes over time. In the center parking is very tight. Further out there are stores with a few parking spots, until you get to the more modern big box stores surrounded by a sea of parking.

After I moved away I came back for a month and tried living without a car. I chose the very best rental location I could, about 13 minute walk to the center of town. While I managed, it required a lot of walking to get to the places I wanted to visit, "a tremendous toll on [my] time" as you say". Santa Fe does have a bus service, but running once per hour and only a few routes. I would not have lived without a car long-term.

I now live in Trollhättan, Sweden, population 60K. While people have lived here for a long time, it didn't become a city proper until a bit over 100 years ago. Sweden was a pretty poor country and it wasn't until the post-war era that people could afford cars. The modern city core was built before widespread car ownership. The apartment building I live in was built around 1960. It's literally on Main Street ("Storgatan" in Swedish). There are two grocery stores in the city center, plus a few others within a mile radius. Both kids (ages 4 and 6) walk to school, which are 3/4 mile away.

The city library, our medical center, the dentist, bank, and more are all within 1/2 mile. That option was not possible in Santa Fe. I had to do a 10 minute drive.

Sweden has become a wealthy country and many Swedes have a single family home with one or two cars. Trollhättan has a lot of suburbs which are not as central as where we live. But they do have frequent bus service with a good network. During peak time I think some of the lines run at 10 minute headways. The regular public busses are also used to carry kids to/from school - Sweden doesn't have dedicated school busses.

We also have big box stores, about 3 miles from where I live, surrounded by a sea of parking. And I can see how it's drawing stores away from the center of town. But unlike Santa Fe, in Trollhättan I can get on the bus (2 blocks away), get a direct bus to the complex, and be dropped off in the middle of the complex area. And those stores are mostly side-by-side and walkable, not separate islands in the sea. See https://www.google.com/maps/place/Överby/@58.313516,12.29464... .

We've lived here now for 10 years, without a car, and I think it's a decent efficient life.

US names:

"Johnson" is a tough one. It's likely not https://en.wikipedia.org/wiki/Lyndon_B._Johnson , because the name is so common that we've had two presidents with that surname. https://en.wikipedia.org/wiki/Andrew_Johnson succeeded Lincoln.

"Roosevelt" could be President FDR but it could also be President Teddy Roosevelt, from which the teddy bear is named. Or it could be someone else.

"Warren" is almost certainly not Warren G. Harding as we rarely named things after someone's first name. Warren is a very common name. For example, Warren, PA was named after Major General Joseph Warren, says https://en.wikipedia.org/wiki/Warren,_Pennsylvania .

Very few of the "Clinton" street names will be for Bill Clinton. It's a very common name. See https://en.wikipedia.org/wiki/Clinton and for a list of US place names with "Clinton" see https://en.wikipedia.org/wiki/Clinton_(disambiguation)#Unite... .

Some of the Clevelands are named after President Cleveland, but some, like Cleveland, OH, are named after Moses Cleaveland (see https://en.wikipedia.org/wiki/Moses_Cleaveland#Founding_of_C... for the spelling difference). Cleveland, MN was named after Cleveland, OH (https://en.wikipedia.org/wiki/Cleveland,_Minnesota).

There are a lot of Douglas names in the US. Two blocks from my childhood home was Douglas Road, named after John Douglas. https://en.wikipedia.org/wiki/Douglas_Road_(Miami)

At this point I don't think it's possible to get much good data out of this data set without years of manual effort.

Toponymy is hard, slow work.

If I understand https://github.com/mihaiolteanu/ulitza/blob/7df974105aaf9776... correctly, it means the 9 mentions of "Polhem" are ignored.

I think it should point to https://en.wikipedia.org/wiki/Christopher_Polhem

"Bellmans" very likely refers to https://en.wikipedia.org/wiki/Carl_Michael_Bellman

Ulricehamn is named in honour of Queen Ulrica Eleonora, https://en.wikipedia.org/wiki/Ulricehamn but I can see how a street containing "Ulricehamn" may be more directly named after the city.

"Sankt Pers" is an older Swedish term for St. Peter. https://sv.wikipedia.org/wiki/Petrus

"Sankt Eriks" is https://en.wikipedia.org/wiki/Eric_IX_of_Sweden

"Nordenskiölds" is difficult since it can refer to several members of the family. https://en.wikipedia.org/wiki/Nordenski%C3%B6ld_(surname) including (and most likely) https://en.wikipedia.org/wiki/Adolf_Erik_Nordenski%C3%B6ld .

"Olof Palme" is https://en.wikipedia.org/wiki/Olof_Palme with at least 5 streets in Google Maps (the entry has a "3", which I guess is the number of entries in the source data).

"Strindberg" is https://en.wikipedia.org/wiki/August_Strindberg

The Tegnérsgatan in Stockholm is named after https://en.wikipedia.org/wiki/Esaias_Tegn%C3%A9r (connection written at https://sv.wikipedia.org/wiki/Tegn%C3%A9rgatan). There are at least 5 different cities with a Tegnérsgatan.

Also, in the US data "Santa Fe", "St. Francis", and "San Francisco" all refer to Saint Francis of Assisi.

"The name "Santa Fe" means 'Holy Faith' in Spanish, and the city's full name as founded remains La Villa Real de la Santa Fé de San Francisco de Asís ('The Royal Town of the Holy Faith of Saint Francis of Assisi').[5][6]" from https://en.wikipedia.org/wiki/Santa_Fe%2C_New_Mexico

"San Francisco was founded on June 29, 1776, when settlers from New Spain established the Presidio of San Francisco at the Golden Gate, and the Mission San Francisco de Asís a few miles away, both named for Francis of Assisi." from https://en.wikipedia.org/wiki/San_Francisco

"Sir Francis Drake" is https://en.wikipedia.org/wiki/Francis_Drake .

The author has take on a very heavy mantle. This is not a task that can easily be automated. Two streets with the same name may easily be named after two different people.

I would say "I live in New Mexico, which is in the southwest US between Texas and Arizona."

It helped that I lived in Santa Fe which, (unlike where your bio implies you live), is a pretty-well recognized US place name in Europe.

One Swedish taxi driver was a fan of Louis L'Amour, and many others know about it through other westerns. An English hotel clerk, base on its reputation, guessed the population was 200K-300K (it was 65K then, 90K now).

That's far from my experience. Where in Europe and for what kind of payments?

I only use POs with my customers. I'm based in Sweden, doing work mostly in Germany, Switzerland, and England, as software sales and contract work. No one has even blinked.

In Swedish it's called a inköpsorder, but often abbreviated PO.

As an example, https://www.betydelse-definition.com/ink%C3%B6psorder has "Inköpsordern (ofta säker man PO som är kort för Purchase Order) är det viktigaste dokumentet i en inköpsverksamhet och är ett avtal mellan två parter. POn definierar vad som köps in och under vilka villkor och förutsättningar."

In English: "The purchase order (often said PO, which is short for Purchase Order) is the most important document in a purchasing operation and is an agreement between two parties. The PO defines what is bought in and under what conditions and requirements."

Looking around, here's a description of purchase order use in the UK: https://gocardless.com/guides/posts/guide-to-purchase-orders...

> Purchase orders are a helpful part of the procurement process, allowing business owners to keep track of incoming orders and to monitor stock levels. It’s a way to see exactly what money is being spent where and at what moment. In some cases, purchase orders are a basic requirement for doing business. Many government agencies and authorities insist upon PO forms being issued before they’ll agree to settle an invoice.

It wasn't hard to find similar examples for other European countries.

Yes. Isn't that the point of the web site?

When the water table is shallow, but deeper than your Louboutins - which is much of Florida - you can drill a well yourself, at low cost.

After all, the technique only works for down to about 20 feet (there's another page on how to extend that to 30 feet), and 7 of the 26 listed success stories are from Florida.
