  • Illicit trade in prescription drugs a growing problem for Dublin’s north inner city

    ughh. The latest scourge is Zopiclone, “zimmos”, which are being dealt openly due to a bureaucratic loophole in enforcement.

  • A programming language for E. coli

    Mind = blown.

    MIT biological engineers have created a programming language that allows them to rapidly design complex, DNA-encoded circuits that give new functions to living cells. Using this language, anyone can write a program for the function they want, such as detecting and responding to certain environmental conditions. They can then generate a DNA sequence that will achieve it. “It is literally a programming language for bacteria,” says Christopher Voigt, an MIT professor of biological engineering. “You use a text-based language, just like you’re programming a computer. Then you take that text and you compile it and it turns it into a DNA sequence that you put into the cell, and the circuit runs inside the cell.”

  • GitHub now supports “squash on merge”

    yay. On the other hand — http://www.thecaucus.net/#/content/caucus/tech_blog/516 is a good explanation of why not to adopt it. Pity GitHub haven’t made it a per-review option…

  • bcc

    Dynamic tracing tools for Linux, a la dtrace, ktrace, etc. Built using BPF, using kernel features in the 4.x kernel series, requiring at least version 4.1 of the kernel

  • US government commits to publish publicly financed software under Free Software licenses

    Wow, this is significant:

    At the end of last week, the White House published a draft for a Source Code Policy. The policy requires every public agency to publish their custom-build software as Free Software for other public agencies as well as the general public to use, study, share and improve the software. At the Free Software Foundation Europe (FSFE) we believe that the European Union, and European member states should implement similar policies. Therefore we are interested in your feedback to the US draft.

  • A Decade Of Container Control At Google

    The big thing that can be gleaned from the latest paper out of Google on its container controllers is that the shift from bare metal to containers is a profound one – something that may not be obvious to everyone seeking containers as a better way – and we think cheaper way – of doing server virtualization and driving up server utilization higher. Everything becomes application-centric rather than machine-centric, which is the nirvana that IT shops have been searching for. The workload schedulers, cluster managers, and container controllers work together to get the right capacity to the application when it needs it, whether it is a latency-sensitive job or a batch job that has some slack in it, and all that the site recovery engineers and developers care about is how the application is performing and they can easily see that because all of the APIs and metrics coming out of them collect data at the application level, not on a per-machine basis. To do this means adopting containers, period. There is no bare metal at Google, and let that be a lesson to HPC shops or other hyperscalers or cloud builders that think they need to run in bare metal mode.

  • How wet is a cycling commute in Ireland?

    It turns out that you’ll get wet 3 times more often if you’re a Galway cyclist when compared to a Dubliner. Dublin is Ireland’s driest cycling city.
    Some good data and visualization on this extremely important issue
