Monthly Archive:: April 2014

The first quarter of 2014 was, again, a hectic and productive time for FreeBSD. The Ports team released their landmark first quarterly stable branch. FreeBSD continues to grow on the ARM architecture, now running on an ARM-based ChromeBook. SMP is now possible on multi-core ARM systems. bhyve, the native FreeBSD hypervisor, continues to improve. An integral test suite is taking shape, and the Jenkins Continuous Integration system has been implemented. FreeBSD patches to GCC are being forward-ported, and LLDB, the Clang/LLVM debugger is being ported. Desktop use has also seen improvements, with work on Gnome, KDE, Xfce, KMS video drivers, X.org, and vt, the new console driver which supports KMS and Unicode. Linux and Wine binary compatibility layers have been improved. UEFI booting support has been merged to head.

Ubuntu 14.04 LTS is the first long-term support release with support for the new "arm64" architecture for 64-bit ARM systems, as well as the "ppc64el" architecture for little-endian 64-bit POWER systems. This release also includes several subtle but welcome improvements to Unity, AppArmor, and a host of other great software.

The result feels a whole lot more mature and a whole lot more capable than its predecessor. The 0.1 version bump, chosen to align the phone platform with its desktop sibling, belies the true nature of this upgrade. It is substantial, and makes Windows Phone tremendously better.

We might still wish that there were a few more apps, and that developers spoke of the platform in the same breath as iOS and Android, but even in spite of this, Windows Phone 8.1 is a polished, fun, clever, and personal smartphone platform that's just about everyone can enjoy. It's a magnificent smartphone platform.

The U.S. National Security Agency knew for at least two years about a flaw in the way that many websites send sensitive information, now dubbed the Heartbleed bug, and regularly used it to gather critical intelligence, two people familiar with the matter said.

The NSA's decision to keep the bug secret in pursuit of national security interests threatens to renew the rancorous debate over the role of the government’s top computer experts.

There's certainly some hope on the horizon with Apple and Google, though just how good these systems will be remains to be seen. One thing is clear, though: the current state of all in-car experiences is incredibly bad. For those manufacturers looking to go it alone, I don't expect much.

In contrast to TPMs, which were designed as fixed-function devices with a predefined feature set, TrustZone represented a much more flexible approach by leveraging the CPU as a freely programmable trusted platform module. To do that, ARM introduced a special CPU mode called "secure mode" in addition to the regular normal mode, thereby establishing the notions of a "secure world" and a "normal world". The distinction between both worlds is completely orthogonal to the normal ring protection between user-level and kernel-level code and hidden from the operating system running in the normal world. Furthermore, it is not limited to the CPU but propagated over the system bus to peripheral devices and memory controllers. This way, ARM-based platforms become effectively kind of a split personality. When secure mode is active, the software running on the CPU has a different view on the whole system than software running in non-secure mode.

Building on Verify apps, which already protects people when they're installing apps outside of Google Play at the time of installation, we're rolling out a new enhancement which will now continually check devices to make sure that all apps are behaving in a safe manner, even after installation. In the last year, the foundation of this service - Verify apps - has been used more than 4 billion times to check apps at the time of install. This enhancement will take that protection even further, using Android's powerful app scanning system developed by the Android security and Safe Browsing teams.

It wasn't meant to be this way. Windows XP, now no longer supported, wasn't meant to be popular. For all its popularity and sustained usage, people seem to have forgotten something important about it: it sucked.

The Ars forums are a place for geeks to hang out and chat about tech, and especially in the light of the hostility shown towards Windows 8, we thought it might be fun to take a look at how our forum dwellers reacted when first introduced to Microsoft's ancient operating system.

HTC's latest flagship device, the One M8, is one of the best Android smartphones now available on the market, but what would happen to it if Google stripped the phone of some of its customizations? That's essentially what the Google Play edition of the new One offers. Plunk down $699 and you'll have access to an unlocked and (mostly) unadulterated version of the M8 with stock Android 4.4 (also known as KitKat).

Heartbleed, a long-undiscovered bug in cryptographic software called OpenSSL that secures Web communications, may have left roughly two-thirds of the Web vulnerable to eavesdropping for the past two years. Heartbleed isn't your garden-variety vulnerability, so here's a quick guide to what it is, why it's so serious, and what you can do to keep your data safe.

Overall the Galaxy S 5 is a solid replacement to the GS4 (and definitely to any previous Samsung device). I find that pretty much all the flagships offer some set of tradeoffs that prevent any one from being the perfect device (iPhone's screen size, GS5's materials, M8's camera). It's unfortunate because I'd really like to crown a single device the king of them all, but instead we're faced with a handful of differing optimization points. Samsung got it almost perfect with the GS5. With a metal body, a rear facing camera with larger pixels (perhaps with some tweaks to camera output processing), a better NAND controller, and stereo front facing speakers, the GS5 would probably be perfect.

It looks like the Internet of Things could be the next big computing battleground, and Microsoft seems willing to sacrifice a few battles in order to win that war. Facebook is chasing virtual reality; Google wants home automation, smartwatches, and internet-connected glasses. More than 200 billion devices are likely to be connected to the internet by 2020, a huge example of the way the technology industry will shift and new battles will emerge. Satya Nadella believes the future isn't Windows desktops, Windows tablets, and Windows Phones. It's not Windows everywhere, it's Microsoft everywhere, offering software and services for every device - including an entire world of interconnected devices that have yet to be built.
