The Google OS is Coming By Year's End - Stephen Vaughan-Nichols CIO.com - Business Tec... - 0 views

  •  
    In an interview with Bloomberg News, Samson Hu, chief of Asus' Eee PC business, said Asus has assigned engineers to develop an Android-based netbook by the end of the year -- though he said it hasn't decided whether to ship such a product. But in this economy, would any company waste expensive engineering on a project that might not ship? I don't think so. Android makes sense for Asus, which has already shown a willingness to back a Linux maverick. As for applications, the wide array of open-source software that all Linux distributions share would be available, but so would Google's Chrome Web browser and its wealth of Web-based applications. You can bet those are going to work very well with Android/Chrome. I'm sure Asus won't be alone in adopting Android. According to Barclays Capital analyst Israel Hernandez, netbooks are the one bright spot in the PC market. Android just makes them cheaper and more profitable.

Out in the Open: Inside the Operating System Edward Snowden Used to Evade the NSA | Ent... - 0 views

  •  
    TAILS anonymous Operating System- excerpt: "When NSA whistle-blower Edward Snowden first emailed Glenn Greenwald, he insisted on using email encryption software called PGP for all communications. But this month, we learned that Snowden used another technology to keep his communications out of the NSA's prying eyes. It's called Tails. And naturally, nobody knows exactly who created it. Tails is a kind of computer-in-a-box. You install it on a DVD or USB drive, boot up the computer from the drive and, voila, you're pretty close to anonymous on the internet. At its heart, Tails is a version of the Linux operating system optimized for anonymity. It comes with several privacy and encryption tools, most notably Tor, an application that anonymizes a user's internet traffic by routing it through a network of computers run by volunteers around the world. Snowden, Greenwald and their collaborator, documentary film maker Laura Poitras, used it because, by design, Tails doesn't store any data locally. This makes it virtually immune to malicious software, and prevents someone from performing effective forensics on the computer after the fact. That protects both the journalists, and often more importantly, their sources. "The installation and verification has a learning curve to make sure it is installed correctly," Poitras told WIRED by e-mail. "But once the set up is done, I think it is very easy to use." An Operating System for Anonymity Originally developed as a research project by the U.S. Naval Research Laboratory, Tor has been used by a wide range of people who care about online anonymity: everyone from Silk Road drug dealers, to activists, whistleblowers, stalking victims and people who simply like their online privacy. Tails makes it much easier to use Tor and other privacy tools. Once you boot into Tails - which requires no special setup - Tor runs automatically. When you're done using it, you can boot back into your PC's normal operating

Google Chrome Listening In To Your Room Shows The Importance Of Privacy Defense In Depth - 0 views

  • Yesterday, news broke that Google has been stealth downloading audio listeners onto every computer that runs Chrome, and transmits audio data back to Google. Effectively, this means that Google had taken itself the right to listen to every conversation in every room that runs Chrome somewhere, without any kind of consent from the people eavesdropped on. In official statements, Google shrugged off the practice with what amounts to “we can do that”.It looked like just another bug report. "When I start Chromium, it downloads something." Followed by strange status information that notably included the lines "Microphone: Yes" and "Audio Capture Allowed: Yes".
  • Without consent, Google’s code had downloaded a black box of code that – according to itself – had turned on the microphone and was actively listening to your room.A brief explanation of the Open-source / Free-software philosophy is needed here. When you’re installing a version of GNU/Linux like Debian or Ubuntu onto a fresh computer, thousands of really smart people have analyzed every line of human-readable source code before that operating system was built into computer-executable binary code, to make it common and open knowledge what the machine actually does instead of trusting corporate statements on what it’s supposed to be doing. Therefore, you don’t install black boxes onto a Debian or Ubuntu system; you use software repositories that have gone through this source-code audit-then-build process. Maintainers of operating systems like Debian and Ubuntu use many so-called “upstreams” of source code to build the final product.Chromium, the open-source version of Google Chrome, had abused its position as trusted upstream to insert lines of source code that bypassed this audit-then-build process, and which downloaded and installed a black box of unverifiable executable code directly onto computers, essentially rendering them compromised. We don’t know and can’t know what this black box does. But we see reports that the microphone has been activated, and that Chromium considers audio capture permitted.
  • This was supposedly to enable the “Ok, Google” behavior – that when you say certain words, a search function is activated. Certainly a useful feature. Certainly something that enables eavesdropping of every conversation in the entire room, too.Obviously, your own computer isn’t the one to analyze the actual search command. Google’s servers do. Which means that your computer had been stealth configured to send what was being said in your room to somebody else, to a private company in another country, without your consent or knowledge, an audio transmission triggered by… an unknown and unverifiable set of conditions.Google had two responses to this. The first was to introduce a practically-undocumented switch to opt out of this behavior, which is not a fix: the default install will still wiretap your room without your consent, unless you opt out, and more importantly, know that you need to opt out, which is nowhere a reasonable requirement. But the second was more of an official statement following technical discussions on Hacker News and other places. That official statement amounted to three parts (paraphrased, of course):
  • ...4 more annotations...
  • 1) Yes, we’re downloading and installing a wiretapping black-box to your computer. But we’re not actually activating it. We did take advantage of our position as trusted upstream to stealth-insert code into open-source software that installed this black box onto millions of computers, but we would never abuse the same trust in the same way to insert code that activates the eavesdropping-blackbox we already downloaded and installed onto your computer without your consent or knowledge. You can look at the code as it looks right now to see that the code doesn’t do this right now.2) Yes, Chromium is bypassing the entire source code auditing process by downloading a pre-built black box onto people’s computers. But that’s not something we care about, really. We’re concerned with building Google Chrome, the product from Google. As part of that, we provide the source code for others to package if they like. Anybody who uses our code for their own purpose takes responsibility for it. When this happens in a Debian installation, it is not Google Chrome’s behavior, this is Debian Chromium’s behavior. It’s Debian’s responsibility entirely.3) Yes, we deliberately hid this listening module from the users, but that’s because we consider this behavior to be part of the basic Google Chrome experience. We don’t want to show all modules that we install ourselves.
  • If you think this is an excusable and responsible statement, raise your hand now.Now, it should be noted that this was Chromium, the open-source version of Chrome. If somebody downloads the Google product Google Chrome, as in the prepackaged binary, you don’t even get a theoretical choice. You’re already downloading a black box from a vendor. In Google Chrome, this is all included from the start.This episode highlights the need for hard, not soft, switches to all devices – webcams, microphones – that can be used for surveillance. A software on/off switch for a webcam is no longer enough, a hard shield in front of the lens is required. A software on/off switch for a microphone is no longer enough, a physical switch that breaks its electrical connection is required. That’s how you defend against this in depth.
  • Of course, people were quick to downplay the alarm. “It only listens when you say ‘Ok, Google’.” (Ok, so how does it know to start listening just before I’m about to say ‘Ok, Google?’) “It’s no big deal.” (A company stealth installs an audio listener that listens to every room in the world it can, and transmits audio data to the mothership when it encounters an unknown, possibly individually tailored, list of keywords – and it’s no big deal!?) “You can opt out. It’s in the Terms of Service.” (No. Just no. This is not something that is the slightest amount of permissible just because it’s hidden in legalese.) “It’s opt-in. It won’t really listen unless you check that box.” (Perhaps. We don’t know, Google just downloaded a black box onto my computer. And it may not be the same black box as was downloaded onto yours. )Early last decade, privacy activists practically yelled and screamed that the NSA’s taps of various points of the Internet and telecom networks had the technical potential for enormous abuse against privacy. Everybody else dismissed those points as basically tinfoilhattery – until the Snowden files came out, and it was revealed that precisely everybody involved had abused their technical capability for invasion of privacy as far as was possible.Perhaps it would be wise to not repeat that exact mistake. Nobody, and I really mean nobody, is to be trusted with a technical capability to listen to every room in the world, with listening profiles customizable at the identified-individual level, on the mere basis of “trust us”.
  • Privacy remains your own responsibility.
  •  
    And of course, Google would never succumb to a subpoena requiring it to turn over the audio stream to the NSA. The Tor Browser just keeps looking better and better. https://www.torproject.org/projects/torbrowser.html.en

    "Where will Microsoft try to drag you today? Do you really want to go there? In the last week of October 1998, a confidential Microsoft memorandum on Redmond's strategy against Linux and Open Source software was leaked to me by a source who shall remain nameless. I annotated this memorandum with explanation and commentary over Halloween Weekend and released it to the national press. Microsoft was forced to acknowledge its authenticity. The press rightly treated it as a major story and covered it (with varying degrees of cluefulness). "

    "Today Android and iOS dominate the smartphone market, combining to provide the operating systems for more than 95 percent of smartphones. Still, not everyone is a fan of the Apple-Google mobile universe. If you're wary of Android's security shortcomings, tired of iOS's overly aggressive auto-correct, or interested in tapping out of the Apple vs. Google mobile war, however, you'll be pleased to know that a number of new open-source mobile OSs are slated to debut in the next year or so. From Canonical's Ubuntu to Firefox to Samsung, several big-name corporations and organizations will release their own open-source smartphone platforms this year. So grab your Tux the Linux Penguin gear and read on. "

How the Web was almost won ... Tim O'Reilly 1998 | Salon - 0 views

  •  
    The Justice Department's antitrust suit and Judge Jackson's finding of fact have focused on how Microsoft used its operating system dominance to wrest control of the Web browser market from Netscape. Perhaps even more significant is the untold story of Microsoft's attempts to corner the Web server market. As someone whose company competes directly with Microsoft, (we sell a Web server called WebSite that runs on Windows NT, and we are active in promoting Perl, Linux and other open-source technologies), I've been privy to some of the not-so-small details that have guided the course of this recent history. And, it seems to me that if it weren't for the work of a small group of independent open-source software developers, the Justice Department intervention might have come too late not just for Netscape but the Web as a whole.

Petabytes on a budget: How to build cheap cloud storage | Backblaze Blog - 0 views

  •  
    Amazing must read!  BackBlaze offers unlimited cloud storage/backup for $5 per month.  Now they are releasing the "storage" aspect of their service as an open source design.  The discussion introducing the design is simple to read and follow - which in itself is an achievement.   They held back on open sourcing the BackBlaze Cloud software system, which is understandable.  But they do disclose a Debian Linux OS running Tomcat over Apache Server 5.4 with JFS and HTTPS access.  This is exciting stuff.  I hope the CAR MLS-Cloud guys take notice.  Intro: At Backblaze, we provide unlimited storage to our customers for only $5 per month, so we had to figure out how to store hundreds of petabytes of customer data in a reliable, scalable way-and keep our costs low. After looking at several overpriced commercial solutions, we decided to build our own custom Backblaze Storage Pods: 67 terabyte 4U servers for $7,867. In this post, we'll share how to make one of these storage pods, and you're welcome to use this design. Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us. Evolving and lowering costs is critical to our continuing success at Backblaze.
