    The college students, who just pleaded guilty to masterminding the unprecedented Mirai botnet, were themselves shocked to see its success. It had infected nearly 65,000 devices in the first 20 hours—doubling every 76 minutes.

    Three college kids running a Minecraft scam are the reason a huge chunk of the internet went down last fall. Seriously.

    SIKEp503 consumes 34 million cycles (10 milliseconds@3.4GHz) and SIKEp751 does it in 103.8 million cycles (30.5 milliseconds@3.4GHz).

    SIDH (and SIKE) are achieving much better performance: on a 3.4GHz Skylake processor, SIKEp503 does KEM (encaps+decaps) in 10 milliseconds! (yeah I know, slow, but amazing speed for supersingular isogenies!)

    SIDH v3.0 includes two scheme sets: SIKEp503/SIDHp503 and SIKEp751/SIDHp751 to match post-quantum security of AES128 and AES192, respect.

    Honestly, I am hopeful that someday a plugin for 's may cover this use case.

    Help! Used to teach web programming with c9.io cloud IDE: free accounts, node, mysql, websockets, simple UI. Now that Amazon is shutting it down, what options do I have? AWS Cloud9 is NOT an option. Codeanywhere, Eclipse Che are all too complicated. Am willing to self-host.

    Excited to officially announce a project we've been working on for nearly a year now: Binder 2.0! Powered by JupyterHub + Kubernetes, it's more scalable, stable, flexible, and easier to deploy on your own. Check it out!

    Awesomeness: Take pure code, converts it to native code, and now let (e.g. an integrator) call this native code with zero overhead.

    Take your capsule and go to the space with @pythran. A LowLevelCallable for using Python function. Awesome work done by Serge Guelton !
