(tags: via:fp pictures photos night colour landscapes long-exposure photography)Occursions : ‘Our goal is to create the world’s fastest extendable, non-transactional time series database for big data (you know, for kids)! Log file indexing is our initial focus. For example append only ASCII files produced by libraries like Log4J, or containing FIX messages or JSON objects. Occursions was built by a small team sick of creating hacks to remotely copy and/or grep through tons of large log files. We use it to index around a terabyte of new log data per day. Occursions asynchronously tails log files and indexes the individual lines in each log file as each line is written to disk so you don’t even have to wait for a second after an event happens to search for it. Occursions uses custom disk backed data structures to create and search its indexes so it is very efficient at using CPU, memory and disk.’

Microsoft’s Azure Feb 29th, 2012 outage postmortem : ‘The leap day bug is that the GA calculated the valid-to date by simply taking the current date and adding one to its year. That meant that any GA that tried to create a transfer certificate on leap day set a valid-to date of February 29, 2013, an invalid date that caused the certificate creation to fail.’ This caused cascading failures throughout the fleet. Ouch — should have been spotted during code review

FOI docs regarding lobbying of Sean Sherlock on the copyright SI : Truly amazing outcome from Mark Tighe’s FOI request regarding lobbying on the copyright SI. It turns out that (a) IRMA want all Irish ISPs to enact “3 strikes”, and view the SI as a way to force this; but (b) Eircom are of the opinion that “3 strikes” is now illegal and unenforceable under EU and Irish law. Despite knowing this, Sherlock then went ahead and signed the SI into law *anyway*, just to avoid the hassle of IRMA’s members bringing the government to court. Which they did anyway, regardless. What an utter shambles

In all likelihood, Sherlock’s department had decided to do it a long time ago (probably before the last election), in a (now failed) effort to get the music companies off its back. It’s a shame that Sherlock has gone along with this so easily: he is taking all the flak.

Facts Are Sacred : A new Irish news site with some familiar names. ‘What is a fact? In philosophy, a fact is something that makes a statement true. In science, it is a verifiable observation. In our case, we take a fact to be something that we can provably demonstrate to be true. This means that we can check the truth of a statement about the current state of affairs but we cannot check claims about the future. Inevitably, as the evidence gets more granular, our view of a fact can change but we should take the scientific approach of going where the evidence leads us, rather than the all too common habit today of starting with a conclusion and looking for supporting data. We are holding ourselves to a high standard and we want you to call us on it where you believe we have fallen short. It is more important that, as readers and writers, we collaborate to put verifiable facts into our daily discourse rather than that we save face. We are looking forward to what we’re sure will be a challenging and rewarding experience and hope you enjoy the ride.’

It’s probably not important that you remember his face because his career in Irish politics may soon be over. […] What’s particularly galling is the government’s high handed act. In the United States they dropped SOPA legislation because voters objected, but in Ireland they just waited for the controversy to die down and railroaded it through.

The other question is how at the flick of a switch do 8,000 sites suddenly get added to a blacklist – for whatever reason – without any kind of oversight. Denmark’s IT-Political Association is critical and has called for ISPs to cease cooperation with the voluntary scheme which operates without any kind of judicial review. “Today’s story shows that the police are not able to secure against manual errors that could escalate into something that actually works as a ‘kill switch’ for the Internet,” the group said in a statement.’

On The Record » The hue and cry over buying and selling tickets : ‘If you really think that all 14,500 tickets for a hot show at Dublin’s O2 like, let’s say, One Direction will go on sale to the general public, you probably also still believe in the tooth fairy. While 10 per cent of the tickets are usually held back for O2’s priority customers, there will always still be far less than the remaining 13,000 tickets available on Ticketmaster’s system when the show purportedly goes on sale. How else do you think tickets for those One Direction Dublin shows in March 2013 can on sale minutes after they are sold out on the supposed primary ticket-selling site, on a secondary site like Viagogo at a hugely inflated premium? Do you really think people queued overnight for those tickets to go “nah, not bothered, have to wash my hair that night” five minutes after getting them in their hands about a show 13 months away? Perhaps we need a Dispatches-type expose over here to lift a few rocks and show the type of fat, avaricious worms wiggling around underneath feasting like parasites on the wallets and credit cards of Irish music fans.’

Many of those whose works were offered derive income not from royalties, but from related activities such as teaching and research. Such people were themselves an important component library.nu’ user base. Some have other means to access the same materials, others, especially those in countries with weaker education infrastructures and more emaciated library budgets, do not. Outside of formal education, the millions of online autodidacts may be denied access to material, seriously impinging on their lives and possibilities. When one considers the cost of text books and more especially scholarly articles, that is no hyperbole, and applies not only to the global south but the post-industrial north as well, awash in its dreams of knowledge economies and human capital.’

The astrology software company that filed the lawsuit, Astrolabe, has also apologized and agreed to a ‘covenant not to sue’ going forward, which will help protect the database from future baseless legal actions and disruptions. Software engineers around the world depend on the time zone database to make sure that time-stamps for email and other files work correctly no matter where you are. However, last September, Astrolabe filed a lawsuit against Arthur David Olson and Paul Eggert – the researchers who coordinated the database’s development for decades – because the database includes information from an atlas in which Astrolabe claimed to own copyright. But facts – like what time the sun rises – are not copyrightable. EFF, along with co-counsel Adam Kessel and Olivia Nguyen at the Boston office of Fish & Richardson P.C, promptly signed on to defend Olson and Eggert and protect this essential tool. In January, EFF advised Astrolabe that Olson and Eggert would move for sanctions if Astrolabe did not withdraw its complaint. Today’s dismissal followed.’

This kind of ad hoc solution is a viable solution to providing logging data to an offline analysis system like Hadoop, but is very limiting for building real-time processing. Kafka aims to unify offline and online processing by providing a mechanism for parallel load into Hadoop as well as the ability to partition real-time consumption over a cluster of machines.’ neat

Using newly-collected data on the sequencing of the human genome by the public Human Genome Project and the private rm Celera, this paper estimates the impact of Celera’s gene-level IP on subsequent scientic research and product development. Genes initially sequenced by Celera were held with IP for up to two years, but moved into the public domain once re-sequenced by the public eort. Across a range of empirical specications, I nd evidence that Celera’s IP led to reductions in subsequent scientic research and product development on the order of 20 to 30 percent. Taken together, these results suggest that Celera’s short-term IP had persistent negative eects on subsequent innovation relative to a counterfactual of Celera genes having always been in the public domain.’ (via Tony Finch)

Why should we stop online piracy? – opinion – 19 January 2012 – New Scientist : ‘There’s no evidence that the US is currently suffering from an excessive amount of online piracy, and there is ample reason to believe that a non-zero level of copyright infringement is socially beneficial.

(Possibly going beyond web blocking to also target hosting and other services.)
