Chromebooks are any laptop that, under license from Google, runs the Linux kernel-based Chrome OS. Chrome OS is incredibly lightweight, drawing almost all of its interface from the Chrome browser. It also supports Chrome apps, and as of late 2016 will be the only platform to get new Chrome apps.

Chromebooks are manufactured by a variety of vendors, such as Google, HP, Acer, Samsung, Dell, and others. They range in price from the mid $100 range to over $1,200 for the Google Pixel. Educational pricing is available as well.

  • How Chromebooks Are About to Totally Transform Laptop Design

    Google’s first Chromebook was the kind of laptop you’d design if you didn’t give a damn about laptop design. It was thick, heavy, rubbery, boring, and black. Black keys, black body, black trackpad, black everything. Everything about the Cr-48 was designed to communicate that this device was still an experiment. Even the name, a reference to an unstable isotope of the element Chromium, was a hint at the chaos raging inside this black box. “The hardware exists,” Sundar Pichai told a crowd of reporters at the Cr-48’s launch event in December of 2010, “only to test the software.”

    Moments later, Eric Schmidt took the stage and preached about how the “network computer” tech-heads had been predicting for decades was finally ready to change the world. “We finally have a product,” Schmidt said, “which is strong enough, technical enough, scalable enough, and fast enough that you can build actually powerful products on it.” Apparently already sensing the skeptical feedback Chrome OS would get, he gestured toward the audience and told them “it does, in fact, work.”

  • 7 Reasons Why You Should Buy a Chromebook

    Chromebook is a different thing from Netbooks with the fact that it does not have Windows being a huge difference. Chromebooks thus run on a fresh and different operating system that while it is not an old OS it isn’t a desktop kind of OS either but a mobile one.

    Chromebooks have pretty hardware, especially if the Haswell processors they are running on, which are energy efficient, are anything to go by. Nonetheless, there are many reasons why buying Chromebooks make a lot of sense.

VintOS Promises to Be the Chromium OS Fork You've Always Wanted and Needed

Dylan Callahan from the Chromium OS for SBCs (Single-Board Computers) project, which unfortunately was discontinued due to lack of interest from users, informed Softpedia today, September 5, 2016, that he's working on a new Linux-based OS.

We have to admit that we're quite surprised to see that developers aren't giving up on their ambitions of creating the best fork of a well-known Linux kernel-based operating system, in this case Chromium OS. While Chromium OS for SBCs was aimed at embedded and IoT devices, the new one is targeted at all PCs.

World, meet VintOS! What's VintOS? Well, it's upcoming open-source fork of Chromium OS, the operating system on which the famous Google Chrome OS is based. To make a name for itself from the get go, VintOS is named after one of the founding fathers of the Internet, Vinton Cerf, and it's explicitly designed with educational purposes in mind.

Gentoo Linux live DVD "Choice Edition"

Gentoo
Reviews

Gentoo One of the wonderful things about Linux is the diversity of the distributions available. Some distributions are very beginner friendly with installers that offer only a few basic options. Others are more complex, requiring knowledge of Linux and skills with the command line to install. Gentoo falls into the more complex category. There is no installer per se, the user just needs to follow instructions to perform several steps leading to a fully installed and configured system. This process is certainly harder than using Ubuntu's Ubiquity installer, but it is not that hard. The instructions are clear and do require previous experience with Linux, or the tenacity to keep going (or start over) when things go wrong when Gentoo is used in a "dive in head first" learning experience. Below, I take a look at the latest Gentoo Linux live DVD, the "Choice Edition," and briefly explore how Gentoo gets installed on a system by using a step by step set of instructions instead of an installer that takes care of most of the steps automatically.

  • Business users force Microsoft to back off Windows 10 PC kill plan

    Microsoft has backed down on its plan to hustle owners of certain PCs to Windows 10 by crimping support options.

    Redmond revealed the plan last January, when it decreed that PCs running 6th-generation Core i5 or Core i7 CPUs and Windows 7 would only get limited security and stability support until mid-2017. By March it backed off a little, extending support for another year and promising critical patches would flow until end of life.

  • Attention, College Students: Chromebooks Are About to Get Awesome

    Here’s some unhelpful back-to-school advice: Don’t buy a laptop. Borrow one, steal one from a family member, buy a piece of junk for 40 bucks on Craigslist. If you can find a way to wait a couple of months before dropping serious coin on a new clamshell, you’ll be glad you did.

    Later this fall, Apple’s almost certainly going to release a new MacBook Pro, which is desperately in need of a revamp. And there will be Windows PCs practically falling from the ceiling—maybe even a few made by Microsoft itself. But the real reason to hold off on your purchase is to wait for the new breed of Chromebooks that are on their way.

The Pentoo Linux development team proudly announces today, August 2, 2016, the availability for download of the fifth Release Candidate (RC) build towards the Pentoo 2015.0 GNU/Linux operating system.

We don't write so often about the Pentoo GNU/Linux operating system because new releases are being made available to the public online when a new DEF CON event (the world's largest annual hacker convention) is taking place. So yes, it's now a tradition to see a new Pentoo release around a DEF CON conference.

It's no secret that Chrome OS has not been the same striking success for Google that the Android OS has been. And yet, Chromebooks--portable computers running the platform--have not only found their niche, but they are also introducing a new generation to cloud computing. Chromebooks are firmly entrenched in the education market, where many young users have become used to the convention of storing apps and data in the cloud.

Now, according to new research from Gartner, Chromebooks are ready to hit new milestones. Analysts there report that Chromebook shipment growth will be in the double digits this year. At the same time, though, Chromebooks have not become fixtures in the enterprise, replacing Windows PCs.

Security: OpenSSL, IoT, and LWN Coverage of 'Intelpocalypse'

  • Another Face to Face: Email Changes and Crypto Policy
    The OpenSSL OMC met last month for a two-day face-to-face meeting in London, and like previous F2F meetings, most of the team was present and we addressed a great many issues. This blog posts talks about some of them, and most of the others will get their own blog posts, or notices, later. Red Hat graciously hosted us for the two days, and both Red Hat and Cryptsoft covered the costs of their employees who attended. One of the overall threads of the meeting was about increasing the transparency of the project. By default, everything should be done in public. We decided to try some major changes to email and such.

  • A look at the handling of Meltdown and Spectre
    The Meltdown/Spectre debacle has, deservedly, reached the mainstream press and, likely, most of the public that has even a remote interest in computers and security. It only took a day or so from the accelerated disclosure date of January 3—it was originally scheduled for January 9—before the bugs were making big headlines. But Spectre has been known for at least six months and Meltdown for nearly as long—at least to some in the industry. Others that were affected were completely blindsided by the announcements and have joined the scramble to mitigate these hardware bugs before they bite users. Whatever else can be said about Meltdown and Spectre, the handling (or, in truth, mishandling) of this whole incident has been a horrific failure. For those just tuning in, Meltdown and Spectre are two types of hardware bugs that affect most modern CPUs. They allow attackers to cause the CPU to do speculative execution of code, while timing memory accesses to deduce what has or has not been cached, to disclose the contents of memory. These disclosures can span various security boundaries such as between user space and the kernel or between guest operating systems running in virtual machines. For more information, see the LWN article on the flaws and the blog post by Raspberry Pi founder Eben Upton that well describes modern CPU architectures and speculative execution to explain why the Raspberry Pi is not affected.
  • Addressing Meltdown and Spectre in the kernel
    When the Meltdown and Spectre vulnerabilities were disclosed on January 3, attention quickly turned to mitigations. There was already a clear defense against Meltdown in the form of kernel page-table isolation (KPTI), but the defenses against the two Spectre variants had not been developed in public and still do not exist in the mainline kernel. Initial versions of proposed defenses have now been disclosed. The resulting picture shows what has been done to fend off Spectre-based attacks in the near future, but the situation remains chaotic, to put it lightly. First, a couple of notes with regard to Meltdown. KPTI has been merged for the 4.15 release, followed by a steady trickle of fixes that is undoubtedly not yet finished. The X86_BUG_CPU_INSECURE processor bit is being renamed to X86_BUG_CPU_MELTDOWN now that the details are public; there will be bug flags for the other two variants added in the near future. 4.9.75 and 4.4.110 have been released with their own KPTI variants. The older kernels do not have mainline KPTI, though; instead, they have a backport of the older KAISER patches that more closely matches what distributors shipped. Those backports have not fully stabilized yet either. KPTI patches for ARM are circulating, but have not yet been merged.
  • Is it time for open processors?
    The disclosure of the Meltdown and Spectre vulnerabilities has brought a new level of attention to the security bugs that can lurk at the hardware level. Massive amounts of work have gone into improving the (still poor) security of our software, but all of that is in vain if the hardware gives away the game. The CPUs that we run in our systems are highly proprietary and have been shown to contain unpleasant surprises (the Intel management engine, for example). It is thus natural to wonder whether it is time to make a move to open-source hardware, much like we have done with our software. Such a move may well be possible, and it would certainly offer some benefits, but it would be no panacea. Given the complexity of modern CPUs and the fierceness of the market in which they are sold, it might be surprising to think that they could be developed in an open manner. But there are serious initiatives working in this area; the idea of an open CPU design is not pure fantasy. A quick look around turns up several efforts; the following list is necessarily incomplete.
  • Notes from the Intelpocalypse
    Rumors of an undisclosed CPU security issue have been circulating since before LWN first covered the kernel page-table isolation patch set in November 2017. Now, finally, the information is out — and the problem is even worse than had been expected. Read on for a summary of these issues and what has to be done to respond to them in the kernel. All three disclosed vulnerabilities take advantage of the CPU's speculative execution mechanism. In a simple view, a CPU is a deterministic machine executing a set of instructions in sequence in a predictable manner. Real-world CPUs are more complex, and that complexity has opened the door to some unpleasant attacks. A CPU is typically working on the execution of multiple instructions at once, for performance reasons. Executing instructions in parallel allows the processor to keep more of its subunits busy at once, which speeds things up. But parallel execution is also driven by the slowness of access to main memory. A cache miss requiring a fetch from RAM can stall the execution of an instruction for hundreds of processor cycles, with a clear impact on performance. To minimize the amount of time it spends waiting for data, the CPU will, to the extent it can, execute instructions after the stalled one, essentially reordering the code in the program. That reordering is often invisible, but it occasionally leads to the sort of fun that caused Documentation/memory-barriers.txt to be written.

US Sanctions Against Chinese Android Phones, LWN Report on Eelo

  • A new bill would ban the US government from using Huawei and ZTE phones
    US lawmakers have long worried about the security risks posed the alleged ties between Chinese companies Huawei and ZTE and the country’s government. To that end, Texas Representative Mike Conaway introduced a bill last week called Defending U.S. Government Communications Act, which aims to ban US government agencies from using phones and equipment from the companies. Conaway’s bill would prohibit the US government from purchasing and using “telecommunications equipment and/or services,” from Huawei and ZTE. In a statement on his site, he says that technology coming from the country poses a threat to national security, and that use of this equipment “would be inviting Chinese surveillance into all aspects of our lives,” and cites US Intelligence and counterintelligence officials who say that Huawei has shared information with state leaders, and that the its business in the US is growing, representing a further security risk.
  • U.S. lawmakers urge AT&T to cut commercial ties with Huawei - sources
    U.S. lawmakers are urging AT&T Inc, the No. 2 wireless carrier, to cut commercial ties to Chinese phone maker Huawei Technologies Co Ltd and oppose plans by telecom operator China Mobile Ltd to enter the U.S. market because of national security concerns, two congressional aides said. The warning comes after the administration of U.S. President Donald Trump took a harder line on policies initiated by his predecessor Barack Obama on issues ranging from Beijing’s role in restraining North Korea to Chinese efforts to acquire U.S. strategic industries. Earlier this month, AT&T was forced to scrap a plan to offer its customers Huawei [HWT.UL] handsets after some members of Congress lobbied against the idea with federal regulators, sources told Reuters.
  • Eelo seeks to make a privacy-focused phone
    A focus on privacy is a key feature being touted by a number of different projects these days—from KDE to Tails to Nextcloud. One of the biggest privacy leaks for most people is their phone, so it is no surprise that there are projects looking to address that as well. A new entrant in that category is eelo, which is a non-profit project aimed at producing not only a phone, but also a suite of web services. All of that could potentially replace the Google or Apple mothership, which tend to collect as much personal data as possible.

Mozilla: Resource Hogs, Privacy Month, Firefox Census, These Weeks in Firefox

  • Firefox Quantum Eats RAM Like Chrome
    For a long time, Mozilla’s Firefox has been my web browser of choice. I have always preferred it to using Google’s Chrome, because of its simplicity and reasonable system resource (especially RAM) usage. On many Linux distributions such as Ubuntu, Linux Mint and many others, Firefox even comes installed by default. Recently, Mozilla released a new, powerful and faster version of Firefox called Quantum. And according to the developers, it’s new with a “powerful engine that’s built for rapid-fire performance, better, faster page loading that uses less computer memory.”
