SUSE and Microsoft give enterprise Linux an Azure tune-up

Veteran penguin botherer feels the need. For speed


Longtime Linux slinger SUSE has emitted a kernel optimised for the cloudy world of Microsoft Azure.

Microsoft's embrace of Linux is well-documented, with even its client OS seeing some penguin-based love in ways that would have been unthinkable a few short years ago. Redmond sees its future in the cloud, and so is keen to remove obstacles to developer adoption.

To this end, SUSE has collaborated with the Windows giant to create a custom-tuned kernel for SUSE Linux Enterprise Server 15 on-demand instances. The pair reckon the tweaked code will consume less RAM while also booting faster. Performance should see an uptick too.

SUSE claimed this tuned kernel, which will be the default for SLES 15 instances in the Azure Marketplace, will see network throughput jump by up to 25 per cent. Latency should be down by 23 per cent.

Microsoft's Ky Srinivasan, general manager of the Enterprise Open Source Group at Microsoft, said: "The new Azure-tuned kernel allows those customers to quickly take advantage of new Azure services such as Accelerated Networking with SR-IOV."

While the tuned kernel will allow users access to the familiar tools and resources that form part of the SUSE Public Cloud Module (including the ability to tinker with Azure through the command prompt) SUSE is keen to point out that it remains possible to drop back to the standard kernel for those nervous about adopting a platform optimised for Azure.

However, switching back to the standard kernel will mean that the newest and shiniest Azure toys may not be immediately available. Purists may well prefer things that way. ®

    America's labor watchdog has given workers at Amazon’s warehouse in Bessemer, Alabama, another crack at voting for unionization after their first attempt failed earlier this year.

    “It is ordered that the election that commenced on February 8 is set aside, and a new election shall be conducted,” Lisa Henderson, regional director at the National Labor Relations Board, ruled [PDF] on Tuesday.

    “The National Labor Relations Board will conduct a second secret ballot election among the unit employees. Employees will vote whether they wish to be represented for purposes of collective bargaining by the Retail, Wholesale and Department Store Union.”

    FluBot, a family of Android malware, is circulating again via SMS messaging, according to authorities in Finland.

    The Nordic country's National Cyber Security Center (NCSC-FI) lately warned that scam messages written in Finnish are being sent in the hope that recipients will click the included link to a website that requests permission to install an application that's malicious.

    "The messages are written in Finnish," the NCSC-FI explained. "They are written without Scandinavian letters (å, ä and ö) and include, for example, the characters +, /, &, % and @ in illogical places in the text to make it more difficult for telecommunications operators to filter the messages. The theme of the text may be that the recipient has received a voicemail message or a message from their mobile operator."

  • AsmREPL: Wing your way through x86-64 assembly language

    Assemblers unite

    Ruby developer and internet japester Aaron Patterson has published a REPL for 64-bit x86 assembly language, enabling interactive coding in the lowest-level language of all.

    REPL stands for "read-evaluate-print loop", and REPLs were first seen in Lisp development environments such as Lisp Machines. They allow incremental development: programmers can write code on the fly, entering expressions or blocks of code, having them evaluated – executed – immediately, and the results printed out. This was viable because of the way Lisp blurred the lines between interpreted and compiled languages; these days, they're a standard feature of most scripting languages.

    Patterson has previously offered ground-breaking developer productivity enhancements such as an analogue terminal bell and performance-enhancing firmware for the Stack Overflow keyboard. This only has Ctrl, C, and V keys for extra-easy copy-pasting, but Patterson's firmware removes the tedious need to hold control.
