“This release is unique in that it’s API-only which means you won’t see any changes on twitter.com, yet. Instead, Twitter applications like Birdfeed, Seesmic Web, Foursquare, Gowalla, Twidroid, Twittelator Pro and others are already supporting this new functionality (go try them out now!) in interesting ways that include geotagging your tweets and displaying the location from where a tweet was posted.”

Examining Twitter’s status update API description shows how one associates a location with a Tweet. Pretty simple.

Since disclosing your location raises privacy concerns, Twitter has made geotagging an opt-in service and also allows users to delete all of the location information associated with their tweets. Moreover, their policy, as described here, says

“We require application developers to be upfront and obvious about when they are Geotagging an update. If you ever find that an application is doing it without notifying you, please let us know.”

Twitter has updated its privacy policy to cover location information.

“Wikipedia uses hundreds of infobox templates for describing various entity types like NFL teams, schools in Canada, train stations etc. These infoboxes are separated and do not use a common vocabulary. Several different spellings of attributes are used for them, which all stand for the same meaning (e.g. birth_place, birthPlace, origin). This poses limitations to checking consistency within Wikipedia infoboxes, amongst different language editions, and it makes it hard for external tools to reuse the information in infoboxes.”

The goals mentioned in the RFC include (1) establishing the currently missing links between synonymous template attributes, (2) enabling authors to use template annotations to check for for factual inconsistencies (e.g., outdated population figures), and (3) providing consensus about which properties should be used in templates and what data they should contain.

According to an article in the WSJ, Europe Approves New Cookie Law, “the Council of the European Union has approved new legislation that would require Web users to consent to Internet cookies..”

The law could have broad repercussions for online ads. “Almost every site that carries advertising should be seeking its visitors’ consent to the serving of cookies,” wrote Struan Robertson, a lawyer specializing in technology at Pinsent Masons and editor of Out-Law.com. “It also catches sites that count visitors — so if your site uses Google Analytics or WebTrends, you’re caught.”

This hit slashdot (“Breathtakingly Stupid” EU Cookie Law Passes) this morning.

By the way, our ebiquity site uses cookies. Send mail to no-more-ebiquity-cookies at cs.umbc.edu if you want to opt out.

Hmmmm. I wonder how we would implement cookie opt-out. I think setting a cookie to indicate that the user has opted out of your site’s cookies would be a good approach.

“The guys who designed Go were very focused on keeping things as small and simple as possible. When you look at it in contrast to a language like C++, it’s absolutely striking. Go is very small, and very simple. There’s no cruft. No redundancy. Everything has been pared down. But for the most part, they give you what you need. If you want a C-like language with some basic object-oriented features and garbage collection, Go is about as simple as you could realistically hope to get.”

“The most innovative thing about it is its type system. … It ends up giving you something with the flavor of Python-ish duck typing, but with full type-checking from the compiler.”

“Go programs compile really astonishingly quickly. When I first tried it, I thought that I had made a mistake building the compiler. It was just too damned fast. I’d never seen anything quite like it.”

“At the end of the day, what do I think? I like Go, but I don’t love it. If it had generics, it would definitely be my favorite of the C/C++/C#/Java family. It’s got a very elegant simplicity to it which I really like. The interface type system is wonderful. The overall structure of programs and modules is excellent. But it’s got some ugliness. … It’s not going to wipe C++ off the face of the earth. But I think it will establish itself as a solid alternative.”

Go sounds like a language that will help you grow as a computer scientist if you use it. That’s a good enough recommendation for me.

“IDGNS: What’s the status of semantic search at Google? You have said in the past that through “brute force” — analyzing massive amounts of queries and Web content — Google’s engine can deliver results that make it seem as if it understood things semantically, when it really functions using other algorithmic approaches. Is that still the preferred approach?

Mayer: We believe in building intelligent systems that learn off of data in an automated way, [and then] tuning and refining them. When people talk about semantic search and the semantic Web, they usually mean something that is very manual, with maps of various associations between words and things like that. We think you can get to a much better level of understanding through pattern-matching data, building large-scale systems. That’s how the brain works. That’s why you have all these fuzzy connections, because the brain is constantly processing lots and lots of data all the time.

IDGNS: A couple of years ago or so, some experts were predicting that semantic technology would revolutionize search and blindside Google, but that hasn’t happened. It seems that semantic search efforts have hit a wall, especially because semantic engines are hard to scale.

Mayer: The problem is that language changes. Web pages change. How people express themselves changes. And all those things matter in terms of how well semantic search applies. That’s why it’s better to have an approach that’s based on machine learning and that changes, iterates and responds to the data. That’s a more robust approach. That’s not to say that semantic search has no part in search. It’s just that for us, we really prefer to focus on things that can scale. If we could come up with a semantic search solution that could scale, we would be very excited about that. For now, what we’re seeing is that a lot of our methods approximate the intelligence of semantic search but do it through other means.”

I interpret these comments to mean that Google’s management still views the concept of semantic search (and the Semantic Web) as involving better understanding of the intended meaning of text in documents and queries. The W3C’s web of data model is still not on their radar.

In his opening remarks, moderator Ludwig Siegele says

“The participants in this debate, including the three guest speakers, all agree that computing is moving into the cloud. “We are experiencing a disruptive moment in the history of technology, with the expansion of the role of the internet and the advent of cloud-based computing”, says Stephen Elop, president of Microsoft’s business division, which generates about a third of the firm’s revenues ($13 billion) and more than half of its profits ($4.5 billion) in the most recent quarter. Marc Benioff, chief executive of Salesforce.com, the world’s largest SaaS provider with over $1.2 billion in sales in the past 12 months, is no less bullish: ‘Like the shift [from the mainframe to the client/server architecture] that roiled our industry in decades past, the transition to cloud computing is happening now because of major discontinuities in cost, value and function.’”

While the debate’s proposition suggests that security or privacy is its focus, it’s really a broader argument about how software services will be delivered in the future in which security is just one aspect.

“Whether and to what extent companies and consumers elect to hand their computing over to others, of course, depends on how much they trust the cloud. And customers still have many questions. How reliable are such services? What about privacy? Don’t I lose too much control? What if Salesforce.com, for instance, changes its service in a way I do not like? Are such web-based services really cheaper than traditional software? And how easy is it to get my data if I want to change providers? Are there open technical standards that would make this easier?”
