Just talk

I've seen it discussed before, but it sometimes doesn't really hit me until I see where someone who is talking around it, completely misses it.

Of course, I'm talking about the Star Trek influence. How close are we to realizing Star Trek Technology?

The Sysadmin's Toolbox: sar

HowTos There's an old saying: "When the cat's away the mice will play." The same is true for servers. It's as if servers wait until you aren't logged in (and usually in the middle of REM sleep) before they have problems. Logs can go a long way to help you isolate those problems.

The truth about Goobuntu: Google's in-house desktop Ubuntu Linux

Filed under
Ubuntu Most Linux people know that Google uses Linux on its desktops as well as its servers. Some know that Ubuntu Linux is Google's desktop of choice and that it's called Goobuntu. But almost no one outside of Google knew exactly what was in it or what roles Ubuntu Linux plays on Google's campus, until now.

Seven Reasons for Choosing LibreOffice over Microsoft Office

Filed under
LibO OK, LibreOffice is free for the download, and you can install it on as many different machines as you choose. But a free price and a free license aren’t much good if the software doesn’t have the features you want.

GNOME Answers Criticisms

Filed under
Software Since GNOME 3 was released in April 2011, the criticism has often been harsh (and, yes, I contributed to it myself). Seventeen months later, it shows few signs of ending. Yet aside from the occasional comment from individuals, the GNOME Project itself has refrained from answering. That is, until now.

Rackspace and FOSS Report

  • The Rackspace State of Open Source
    As the OpenStack Summit in Barcelona kicks off, Rackspace has released a report entitled ‘The State of Open Source’. With every conference seemingly extolling the virtues of open source software, this report is timely. It manages to differentiate between enterprise open source and the wider open source software market.
  • Why digital transformation needs open source
    As if there wasn't already ample reason for businesses to switch to open source, Forrester analysts Paul Miller and Lauren E Nelson released a report in April 2016, entitled Open Source Powers Enterprise Digital Transformation — CIOs Need To Embrace Open Source Software To Drive Change, which further drives the point.
  • Despite Security Fears, Open Source Is Fuelling Innovation and Cost Savings in UK Businesses
  • Security concerns fail to hold back UK open source success
    However, despite its increasingly common use, many (54%) still perceive external security threats to be a big barrier to adoption, that’s according to a report published by Rackspace. The State of Open Source study, which was conducted among IT decision makers in UK businesses with over 1,000 employees and revenues over £500m, and looks at the ways open source is being used, its benefits, but also what is holding back adoption and business concerns. According to the report open source has come of age with 85% using open source technology to migrate a closed source project to open source. Open source also isn’t just a tool for small businesses; the vast majority (90%) of large businesses are now deploying open source-based enterprise applications, with 25% being completely open source. The reason for the growing adoption is because of the money and time savings. Rackspace found that for each project that had been migrated to open source technology, six out of ten organisations saved on average £30,146 and reduced project lifecycle by six months. Greater innovation was reported by many (49%), and 46% were driven to open source because of the competitive opportunities. Additionally, just under half (45%) said that it enabled them to get products and services to market faster. John Engates, Chief Technology Officer at Rackspace, said: “While open source technologies have been around for many years, it is great to see that enterprise businesses are finally dipping their toes in and seeing the tangible benefits.

Security Leftovers

  • The internet apocalypse map hides the major vulnerability that created it
    During Friday’s massive distributed denial of service (DDoS) attack on DNS service provider Dyn, one might be forgiven for mistaking the maps of network outages for images of some post-apocalyptic nuclear fallout. Screenshots from sites like showed menacingly red, fuzzy heat maps of, well, effectively just population centers of the United States experiencing serious difficulty accessing Twitter, Github, Etsy, or any of Dyn's other high-profile clients. Aside from offering little detail and making a DDoS literally into a glowing red menace, they also obscured the reality of just how centralized a lot of internet infrastructure really is. DNS is ground zero for the uneasy tension of the internet’s presumed decentralized resilience and the reality that as of now, translating IP addresses into domain names requires some kind of centralized, hierarchical platform, and that’s probably not going to radically change anytime soon. Other maps provided by various business to business network infrastructure companies weren’t much more helpful. These maps seem to exist mostly to signal that the companies in question have lots of cool data and that it can be made into a flashy map — which might impress potential customers, but that doesn’t offer a ton of insights for the layperson. For example, threat intelligence company Norse's map appears to be mostly a homage to the Matthew Broderick movie War Games: a constant barrage of DDoS attacks beaming like space invader rockets across a world map. Akamai has an impressive 3D visualization that renders traffic as points beaming into the atmosphere. And website monitoring service Pingdom offers a dot map at such a far-out zoom level that it's essentially useless for seeking out more meaningful patterns than "outages happen in population centers, also there are a lot of outages."
  • CoreOS Patched Against the "Dirty COW" Linux Kernel Vulnerability, Update Now
  • World’s first hack-proof router launched
    Turris Omnia router, tagged the world’s first hack-proof router, was launched yesterday at the CES Unveiled Show in Prague, Czech Republic. As an essential part of any home internet network, routers are rather poorly secured and protected against cyber attack. More often than not, the only security feature is the default password. With easily required internet knowledge and some skills, these routers can be hacked, providing unauthorized access to a complete internet network. From there on, anything is possible.

ARM/FPGA module runs Linux on Arria 10 SoC

iWave’s rugged, Linux-friendly, 95 x 75mm “Arria 10 SoC Module” expands upon the dual-core, ARM/FPGA SoC from Altera with DDR4 and 24 transceivers. The iWave Systems Arria 10 SoC Module builds upon Intel/Altera’s Arria 10 SX SoC, a faster, newer sibling to the Cyclone V SX, which iWave tapped for its Qseven based iW-RainboW-G17M-Q7 COM and iW-RainboW-G17D development board combo. Both the Cyclone V SoC and Arria 10 SoC combine dual-core Cortex-A9 subsystems with FPGA circuitry, but the Arria 10 boosts the ARM clock speed to 1.5GHz, up from 800MHz, and offers a higher end FPGA.
