Command Line Tool to Monitor Linux Containers Performance - 0 views

  •  
    "ctop is a new command line based tool available to monitor the processes at the container level. Containers provide operating system level virtualization environment by making use of the cgroups resource management functionality. This tool collects data related to memory, cpu, block IO and metadata like owner, uptime etc from cgroups and presents it in a user readable format so that one can quickly asses the overall health of the system. Based on the data collected, it tries to guess the underlying container technology. ctop is useful in detecting who is using large amounts of memory under low memory situations."

'Let's Encrypt' Project Strives To Make Encryption Simple - Slashdot - 0 views

  • As part of an effort to make encryption a standard component of every application, the Linux Foundation has launched the Let's Encrypt project (announcement) and stated its intention to provide access to a free certificate management service. Jim Zemlin, executive director for the Linux Foundation, says the goal for the project is nothing less than universal adoption of encryption to disrupt a multi-billion dollar hacker economy. While there may never be such a thing as perfect security, Zemlin says it's just too easy to steal data that is not encrypted. In its current form, encryption is difficult to implement and a lot of cost and overhead is associated with managing encryption keys. Zemlin claims the Let's Encrypt project will reduce the effort it takes to encrypt data in an application down to two simple commands. The project is being hosted by the Linux Foundation, but the actual project is being managed by the Internet Security Research Group. This work is sponsored by Akamai, Cisco, EFF, Mozilla, IdenTrust, and Automattic, which all are Linux Foundation patrons. Visit Let's Encrypt official website to get involved.

    The blurb is a bit misleading. This is a project that's been under way since last year; what's new is that they're moving under the Linux Foundation umbrella for various non-technical suoport purposes. By sometime this summer, encrypting web site data and broadcasting it over https is  slated to become a two-click process. Or on the linux command line: $ sudo apt-get install lets-encrypt $ lets-encrypt example.com This is a project that grew out of public disgust with NSA surveillance, designed to flood the NSA (and other bad actors) with so much encrypted data that they will be able to decrypt only a tiny fraction (decryption without the decryption key takes gobs of computer cycles).  The other half of the solution is already available, the HTTPS Everywhere extension for the Chrome, FIrefox, and Opera web browsers by the Electronic Frontier Foundation and the TOR Project that translates your every request for a http address into an effort to connect to an https address preferentially before establishing an http connection if https is not available. HTTPS Everywhere is fast and does not noticeably add to your page loading time. If you'd like to effortlessly imoprove your online security and help burden NSA, install HTTPS Everywhere.

Sun pitches new cloud as 'Open Platform' * - 0 views

  •  
    Sun takes on the problem of interoperability and portability of applications in a world where there will be many many clouds. At the roll out of the Sun Cloud, key executives explain Sun's implementation of Open Cloud API's and what they see as a pressing need for management tools that will allow some standardization across clouds.

    Sun's Open Cloud API plan is a clean reuse of existing Open Web API's.

    "..... The underpinning of the Open Cloud Platform that Sun will be pitching to developers is a set of cloud APIs, the creation of which is focused under Project Kenai and which has been released under a Community Commons open source license. Sun wants lots of feedback on the APIs and wants these APIs to become a standard too, hence the open license. These APIs describes how virtual elements in a cloud are created, started, stopped, and hibernated using HTTP commands such as GET, PUT, and POST...."

    "...... The upshot is that these APIs will allow programmatic access to virtual infrastructure from Java, PHP, Python, and Ruby and that means system admins can script how virtual resources are deployed. The APIs, as co-creator Tim Bray explains in his blog, are written in JavaScript Object Notation (JSON), not XML. The Q-Layer software is a graphical representation of what is going on down in the APIs, and you can moving virtual resources into the cloud with a click of a mouse using the dashboard or programmatically using the APIs from those four programming languages listed above. (PHP support is not yet available, but will be)....."
  •  
    I can see why Sun picked those four languages first. Can I assume that with a bit of work, this API will be usable from any language with a C "foreign function interface", such as Perl, Common Lisp, Bourne shell, Squeak Smalltalk, and others that your server application might be written in?
  •  
    I read this comment that largely answers my question at: http://www.tbray.org/ongoing/When/200x/2009/03/16/Sun-Cloud "So right now JSON out of a shell tool is not so good. More things like this will create pressure for development of tools to change that, but years of widespread XML/HTML deployment have only produced a few oddly maintained tools. Perhaps that's because you can scrape quite a bit of the web with a couple sed passes, and if I were to have to deal with the mentioned tools, that's probably the route I'd take." (seth w. klein) In other words, with a bit of work, _anything_ that can talk text over HTTP can do this with a bit of work, but an object-oriented is likely to be more at home with JSON (JavaScript Object Notation)

    "I came across Salt while searching for an alternative to Puppet. I like puppet, but I am falling in love with Salt :). This maybe a personal opinion but I found Salt easier to configure and get started with as compared to Puppet. Another reason I like Salt is that it let's you manage your server configurations from the command line, for example:"

Last Call Working Draft -- W3C Authoring Tool Accessibility Guidelines (ATAG) 2.0 - 1 views

  • Examples of authoring tools: ATAG 2.0 applies to a wide variety of web content generating applications, including, but not limited to: web page authoring tools (e.g., WYSIWYG HTML editors) software for directly editing source code (see note below) software for converting to web content technologies (e.g., "Save as HTML" features in office suites) integrated development environments (e.g., for web application development) software that generates web content on the basis of templates, scripts, command-line input or "wizard"-type processes software for rapidly updating portions of web pages (e.g., blogging, wikis, online forums) software for generating/managing entire web sites (e.g., content management systems, courseware tools, content aggregators) email clients that send messages in web content technologies multimedia authoring tools debugging tools for web content software for creating mobile web applications
  • Web-based and non-web-based: ATAG 2.0 applies equally to authoring tools of web content that are web-based, non-web-based or a combination (e.g., a non-web-based markup editor with a web-based help system, a web-based content management system with a non-web-based file uploader client). Real-time publishing: ATAG 2.0 applies to authoring tools with workflows that involve real-time publishing of web content (e.g., some collaborative tools). For these authoring tools, conformance to Part B of ATAG 2.0 may involve some combination of real-time accessibility supports and additional accessibility supports available after the real-time authoring session (e.g., the ability to add captions for audio that was initially published in real-time). For more information, see the Implementing ATAG 2.0 - Appendix E: Real-time content production. Text Editors: ATAG 2.0 is not intended to apply to simple text editors that can be used to edit source content, but that include no support for the production of any particular web content technology. In contrast, ATAG 2.0 can apply to more sophisticated source content editors that support the production of specific web content technologies (e.g., with syntax checking, markup prediction, etc.).

Study: IT jobs will drop in 2009 - 0 views

  • A second survey showed that basic PC and network hardware, as well as professional services providers, would bear the largest proportion of spending cuts. It also showed that CIOs planned to emphasize economizing measures over investments in new technologies, with cloud computing emerging as the last item on their priority lists, despite the hype around it.
  • The CIOs indicated that server virtualization and server consolidation are their No. 1 and No. 2 priorities. Following these two are cost-cutting, application integration, and data center consolidation. At the bottom of the list of IT priorities are grid computing, open-source software, content management and cloud computing (called on-demand/utility computing in the survey) -- less than 2% of the respondents said cloud computing was a priority.

U.S. military closer to making cyborgs a reality - CNNPolitics.com - 0 views

  • The U.S. military is spending millions on an advanced implant that would allow a human brain to communicate directly with computers.If it succeeds, cyborgs will be a reality.The Pentagon's research arm, the Defense Advanced Research Projects Agency (DARPA), hopes the implant will allow humans to directly interface with computers, which could benefit people with aural and visual disabilities, such as veterans injured in combat.The goal of the proposed implant is to "open the channel between the human brain and modern electronics" according to DARPA's program manager, Phillip Alvelda.
  • DARPA sees the implant as providing a foundation for new therapies that could help people with deficits in sight or hearing by "feeding digital auditory or visual information into the brain."A spokesman for DARPA told CNN that the program is not intended for military applications.
  • But some experts see such an implant as having the potential for numerous applications, including military ones, in the field of wearable robotics -- which aims to augment and restore human performance.Conor Walsh, a professor of mechanical and biomedical engineering at Harvard University, told CNN that the implant would "change the game," adding that "in the future, wearable robotic devices will be controlled by implants."Walsh sees the potential for wearable robotic devices or exoskeletons in everything from helping a medical patient recover from a stroke to enhancing soldiers' capabilities in combat.The U.S. military is currently developing a battery-powered exoskeleton, the Tactical Assault Light Operator Suit, to provide superior protection from enemy fire and in-helmet technologies that boost the user's communications ability and vision.The suits' development is being overseen by U.S. Special Operations Command.In theory, the proposed neural implant would allow the military member operating the suit to more effectively control the armored exoskeleton while deployed in combat.

  • In its announcement, DARPA acknowledged that an implant is still a long ways away, with breakthroughs in neuroscience, synthetic biology, low-power electronics, photonics and medical-device manufacturing needed before the device could be used.DARPA plans to recruit a diverse set of experts in an attempt to accelerate the project's development, according to its statement announcing the project.
  •  
    Let's assume for the moment that DARPA's goal is realizable and brain implants for commuication with computers become common. How long will it take for FBI, NSA, et ilk to get legislation or a court order allowing them to conduct mass surveillance of people's brains? Not long, I suspect.

Google confirms that advanced backdoor came preinstalled on Android devices | Ars Technica - 0 views

  • Criminals in 2017 managed to get an advanced backdoor preinstalled on Android devices before they left the factories of manufacturers, Google researchers confirmed on Thursday. Triada first came to light in 2016 in articles published by Kaspersky here and here, the first of which said the malware was "one of the most advanced mobile Trojans" the security firm's analysts had ever encountered. Once installed, Triada's chief purpose was to install apps that could be used to send spam and display ads. It employed an impressive kit of tools, including rooting exploits that bypassed security protections built into Android and the means to modify the Android OS' all-powerful Zygote process. That meant the malware could directly tamper with every installed app. Triada also connected to no fewer than 17 command and control servers. In July 2017, security firm Dr. Web reported that its researchers had found Triada built into the firmware of several Android devices, including the Leagoo M5 Plus, Leagoo M8, Nomu S10, and Nomu S20. The attackers used the backdoor to surreptitiously download and install modules. Because the backdoor was embedded into one of the OS libraries and located in the system section, it couldn't be deleted using standard methods, the report said. On Thursday, Google confirmed the Dr. Web report, although it stopped short of naming the manufacturers. Thursday's report also said the supply chain attack was pulled off by one or more partners the manufacturers used in preparing the final firmware image used in the affected devices.
