For people interested in the relationship between algebra and geometry, there is a quite rigorous, yet not too long discussion of these topics in the "Elements of Geometry for Computer Vision" [1].

It comes the from the engineering end and finds a good balance between going into too much depth and introducing the necessary theory for bridging algebra and geometry. E.g. representing motion as a change in basis in linear space, the perspective camera as a mathematical model, etc.

Is it? Intel has been purchasing large quantities of green energy for years. In the last few year it has been 100% of the their overall consumption [1]. Is there any difference in what the two companies are trying to achieve?

Certain services (Search, Gmail, YouTube) are inaccessible from Slovakia and the Czech Republic.

This article is quite ignorant of any history. It might be cool for preschoolers to find flags with similar geometry and colors, but making any conclusions without mentioning the historical context is wrong.

Why would "The Traditional view" be traditional when it represents just a fraction of the relevant history that shaped the culture of European countries? The same goes for "Historical and cultural divide".

Let's take Central Europe as an example - the "Traditional view" was valid for 45 years (during the Cold War) and does not hold for more than 25 years now. The article also dismisses roughly 300 years of the Habsburg Monarchy, 100 years of Austia-Hungary and the years preceding the Cold War.

These lightly ignored years are important when speaking of any cultural divide as tradesmen, craftsmen, students, etc. moved around the empires and exchanged goods and knowledge with each other. Travelling around European towns and villages shows how the builders and craftsmen influenced each other - in regions much larger than the current states.

Is there a way to find for how long they use the app before deleting it? Can you track the activity of the user, e.g. number of tasks added per day? Or, in other words, are you losing long-term users or the ones that are trying out 5 different todo/reminder apps just to pick the one they like the most?

I went down the same road - using mdadm and a UPS instead of a HW RAID controller with battery backup unit. LSI MegaRAID SAS 9261-8i SGL with a battery backup costs roughly 650 EUR; Eaton 9130i 1500VA Rack 2U UPS costs 850 EUR. So it's a bit more expensive, but you would be buying that UPS anyway.

I think it's a macro. A company that builds companies.

I have to admit that it comes close to Volvo's best achievement today. But not quite. I've managed to cram a 2m (6.6 ft) ladder into my 15 years old S40. Which makes me even more fond of it than ever before.

It has no touch screens - just terrific hardware controls. No fancy electronics, manual transmission, a 2.0l petrol engine without turbos (not even one). All this makes me believe that this incredibly sleek and calm vehicle has its best days ahead of it! I got a bit carried away, still, that durability and utility of these older Volvos... There is something refined about them even when carrying ladders around.

Are all these icons black-and-white? It seems to be fashionable to use monochrome colors for icons these days (Gmail, many mobile and desktop apps). It makes for a sleek and calm interface. I think its choosing the easy way out. Instead of picking a good pallet and shapes, just remove the colors and all of a sudden a seemingly unrelated set of graphics has something very distinctive in common (it worked particularly well for me in a small newspaper where low quality photos were contributed by different authors, just make them grayscale, voila).

Really, color is such a great way to convey information.

What kind of scanner/imaging equipment is needed for the studies? It's not quite clear to me from the article.

On a related note. Which python library would you recommend for text-based interfaces? I have never used ncurses, so I don't know how complex it is. What I would like to achieve is having a user launch my script from the command line, use the text based interface to select a source and destination folder, set a few parameters and show a progress bar.

We need new countries as much as spaces between sentences and question marks.

I am quite sure that by "scaling" he meant the scaling of their business activities and not software.

"... Google offers to bring that scale to us. For me, ultimately building great products is key.... ...you have to look at markets outside of the US. We are doing very well in the US and Canada but we need to get to Europe and around the globe. Just getting to UK has taken up a lot of time and energy and when you look at Europe, there are many countries and many opportunities. It is an atoms-based business and a lot goes into getting it to scale — legal, physical distribution and even localization are time consuming and need new kind of scale."

"The Visual Display of Quantitative Information" is not a howto guide. It's not a list of 101 tips and tricks for drawing charts, where one would wish for 200 tips instead. It's a framework, a theory, of how to think and reason about visualizing information. It is something you can take and apply in many different situations. Then the question really is, is there anything wrong with the theory it conveys?

As a matter of fact, I do speak the language. A lot of things feel weird to me when I come to visit the city. I have this uneasy feeling about things like the Hungarian Guard [1][2] - a paramilitary group having a rally on the most most important square in Budapest. Or having a fascist party, as the 3rd biggest, in the Parliament [3].

Yet, there is an incredible amount of gifted people, who are the exact opposite of these jerks. I guess a lot of people here admire undertakings like Prezi, LogMeIn, ArchiCAD/Graphisoft, or Ustream, all coming from Budapest.

I can't help myself, but Twitter seems to me like a subset of Facebook. Something like ICQ, AIM, or Yahoo Messenger is to Facebook Chat or Skype.

It came at the right time in the US, but it takes some time for these things to get abroad. While it arrived to Central Europe, Facebook had enough users and introduced features like Followers etc. Today, Twitter is solely used by a marginal tech/hip/geek community here.

And advertising goes where people go. The question is, whether this evidence suggests that the Twitter of today can't compete directly with Facebook, and it's success is based on acquiring users before FB matched it in functionality. How stable this user base is? Is it a similar case as with the chat applications?

Anecdotal evidence - a friend of mine just asked, whether one should invest in Twitter... on Facebook.

Thats probably more money than the size of the whole European self-storage industry. I'm really curious, why are these services so popular in the US? What do you store there? When? E.g. when I have something I don't want to get rid of just yet (furniture, spare parts...), I put it in the basement of our apartment house. Although, I can imagine using self-storage when moving.

The good (well...) news is that the curved lines can't even be seen, when the logo is shrinked :)

I found an interesting figure [1] for those of us who could name a few, but are not as well versed in the geography of Britain. It compares British cities to similar European cities by population. The scale is unnecessarily skewed, though.

Software is eating the world. For real now. And it is eating hardware. This is such a strong force that even old time franchises like Microsoft and Motorola can't do anything about it. And apparently "pure software" companies don't mind venturing into it. They know it's software, for the most part, and believe vertical integration is worth the trouble with the messy hardware parts.

How deep is the integration anyway? Did Google and Microsoft end up owning the manufacturing plants? Apple is known to outsource the manufacturing itself.

And that's the reason I am packing my stuff and heading to London. At this very moment. I was just about to remove the legs from the table I am writing these lines on (well, I am writing them on a computer, but thats not the point). And surprise, surprise, I am moving from Central Europe. And yes, I can speak with a thick Slovak, Czech, and Hungarian (Andy Grove style) accent. If anyone had a job available for a fresh CS graduate, please let me know (email is in my profile)!

What I really like about the search, is that it accounts for seasons on different hemispheres. E.g. it returns Lisboa and Cadiz as places similar to Sydney. Even though the months with hot weather are different in the Northern and Southern Hemispheres.

As a side note - clicking the name of a place shows an overlay in the graph. It was not obvious at first; the names are in black.

Try the local names. Praha, Wien, and some unknown mystical name the Dubliners use.
