K2C Polygons

I just got around to comparing the FSA Polygons that I have crowdsourced on geocoder.ca with the ones that were released a few years back by Statistics Canada after they talked Canada Post into it.

The results are surprising. The “official” polygons for the FSA’s seem to leave out quite a bit of the area they actually cover. litkovskaya profile I know this for a fact, because K2C 1N5 is my postal code. The crowdsourced FSA’s, (available for free download here) are the best approximations for FSA polygons.

See for yourself:

What’s the point?

I was looking at an article about the last world cup semifinal (here) and noticed something strange. I could view all videos embedded in the article except one. A blank screen in that little square had one of those stupid copyright notices you see these days: “This video is not authorized for your location (Canada)”



Well, how do they know my location? The ip address of course. So, I switch to an anonymous browser and watch the silly thing. (I wasn’t even that curious to see that, only went into the extra trouble because of this)  But still, what is the point?

With over 40 buy cheap essay years of experience, we caughtinkitchen.com/ take great pride experiencesocotra.com/ in our reputation as the preferred drycleaner of the Greater Harrisburg area.

Is the open internet becoming a regional internet, where you may only access certain content based on your physical real world location? I thought the whole idea of the decentralized internet had defeated that whole concept.

IP address location is pretty useful, I’ve recently added it on my geocoding api, but this is absolutely one of the worst possible uses of this technology. It will simply drive more and more people to do what I just did, that is, hide their ip address.



I gave a talk at State of the Map openstreetmap.org conference on crowdsourcing. (The slides are posted on my twitter feed https://twitter.com/geolytica/status/531501476708114432 , also available on Vimeo)

One observation I took home from the conference is that the state of public data around the word is similar to that in Canada, in the sense that governments and their affiliate entities hold on to the data for as long a possible, despite the fact that doing so, adversely affects the state of their economies and goes against the public good. (According to OSM France “Bano” project, a country loses up to 0.5% of its GDP due to lack of publicly available addressing data. Source)

Crowdsourcing the data is not an optimal solution, in the face of the lack a data feed from its authoritative source, because it results in datasets that contain errors. Still, this seems the only way to open up the data in my view, when the decision makers are convinced that keeping the data closed is better for their budgets (an interesting figure of 0.5 billion pounds was thrown around as the value of a closed post code list by the Royal Mail CEO Moya Greene, in her arguments for keeping the dataset closed. She also happened to be Canadapost’s CEO at the time they started their legal efforts aimed at enforcing CP’s alleged intellectual rights over Canadian postal codes.)

In France on the other hand they don’t have such problems, as they have not yet made the effort to create a post code system like the Canadian or the British ones, hence it is hard to make the half billion dollar argument there, still that does not mean that whatever system they have is open. People from the “Bano” project had to lobby hard to get the list of up to 1000 postal codes created by the French postal service open to the public, and when they actually did it was full of errors. Not only that but the French postal service has 4 different street address datasets (one for regular mail, one for advertising mail,  one for parcels and another one for a purpose I can’t remember now.) All 4 have quality issues, and the 4 different departments that created them do not talk nor cooperate with each other to improve their respective datasets. Funny stories of government inefficiency at the public’s expense. The Economist also wrote a piece on this topic a month ago.

In closing, public data all around the world is at various stages of unavailability because certain people of influence are convinced they are worth a lot of money. Nobody has yet shown how much money they are actually making from licensing this data. I doubt it is half a billion. Or 0.5% of the GDP.

I am certain it is more akin to a hidden tax we all have to pay.



Time determines everything.

If you are smart or dumb (aka a retard), right or wrong (right on time), lucky or unlucky (wrong place, wrong time vs right time).

People complain that “time is short” which is really dumb since no one has ever come up with a measuring stick for time. They also use this word in other meaningless contexts like (“The time is now”, “time is up”, “down time”, “up time”, “a good time”, “a bad time”, “an ok time.”)

When someone complains that they “have no time”, they actually mean that they are not “fast enough”, i.e they are some sort of a retard considering the amount of work that is required of them in a set amount of time.

They do have time, the aforementioned set amount, but they are slow. They are even too slow to admit that, hence the justification of “I have no time.”

A justification requires less time to come by than the truth. That’s why so many of us, slow ones, opt for the first one. Idiots, retards!

An opinion takes even less time, sometimes. Some great things take almost no time at all. They happen in a split second. The rest is just boring repetition by slower people.

Everybody has lots of time. Even the ones that have been recently diagnosed with a fatal disease. By lots of time, I mean time to devote to the things that matter. If you are fast enough.

But, sometimes it is no fun to be fast. Sometimes the best use of your time is to let it go by, and think of something nice, anything but the passing of time.

Eventually everything will come into view.

Give it time.




Thanks for your time.

I have never seen a purple cow

and i do not think that one exist

but if it does you’d better look out

not to mistake it for a purple sheep

(Anonymous) Access Denied

I wrote a few weeks ago how you can save money by being anonymous. More specifically about purchasing a plane ticket with expedia.com, which as one of the many websites in the industry, marks up their prices using the information they get about you from your regular browser.

Well, it seems like now, a couple of weeks later they have blocked access from anonymous browsers.

tor is denied

tor is denied








So, the only other option remains tunneling your connection via your own proxy. Otherwise, if you are getting at their website via an expensive laptop, or any one of your personal information vendors tells them a bit about your buying habits, you are on the hook.

Be anonymous, save money

I was doing some research on plane tickets for a summer trip using several major booking companies (Expedia, Travelocity, etc)

In the course of this research I discovered a little trick that will be beneficial to all, except the aforementioned booking websites.

If you use a browser that makes you anonymous (for example Tor), or just browse via a SSH Tunnel SOCKS Proxy, you will get cheaper prices.

Making the same exact query within a one minute timeframe from a regular browser and an anonymized browser confirms this fact. (the regular browser results were always +$100 more than the ones from the anonymized one)
The writer has followed all the instructions in the order. His writing skills exceeded my expectations. Thanks for writing a good thesis. Great work!
Bottom line, If they know who you are they will charge you more.

PS. It is funny to also note that upon opening the Expedia website from my SSH tunneled browser I got a pop-up window asking me to identify myself via a number of options in exchange for a $25 coupon. The difference in price between the two methods? $134!!. Thanks, but no thanks. Give it a try!
