Speeding up Chrome on Macs

Google’s Chrome is my favorite Web browser on any platform. On Macs, though, I’ve noticed that it has a tendency to get really, really slow over time. I checked into this and I’ve found two common reasons for this and their solutions.

1) Adobe Flash crashes and slow performance

The first problem actually springs from one of Chrome’s features. Chrome comes with Adobe Flash built into the browser so you don’t need to download it. But, say you use another browser, such as Safari or Firefox, on the same Mac, guess what happens? That’s right, you end up with a downloaded copy of Flash and Chrome’s native Flash player.

The immediate result is Chrome will run slower. You will also start to see Flash crashes in the browser as the browser grows increasing confused about which version of Flash to call.

Netflix & Disney: The Good News & The Bad News

People like to moan about there not being anything to watch on Netflix are over-joyed that Netflix has just signed an exclusive movie deal with Disney. I’m excited about it too, but there’s one little thing we all seem to be forgetting: We’re not going to see any of this new big-time content until 2016. 

Don’t get me wrong. It’s a great deal. In the short run, by 2013, Netflix will be getting “high-profile Disney direct-to-video new releases.” In other words, that’s not going to be top favorite titles such as Beauty and the Beast or Lion King but I’m sure it will be something that your children will like. Netflix will also be some older Disney titles in the same time-frame. This will include such movies as Dumbo, Pocahontas, and Alice in Wonderland.

Open-source MariaDB, a MySQL fork, challenges Oracle

MariaDB, an open-source database management system (DBMS) and MySQL fork has been gaining inroads in enterprise software and its founders formed a foundation, the MariaDB Foundation, to promote its software.

Specifically, “the MariaDB Foundation exists to improve database technology, including standards implementation, interoperability with other databases, and building bridges to other types of database such as transactional and NoSQL. To deliver this the Foundation provides technical work in reviewing, merging, testing, and releasing the MariaDB product suite. The Foundation also provides infrastructure for the MariaDB project and the user and developer communities.”

This might strike you as much ado about nothing. What’s another DBMS in a world where Oracle owns the most popular open-source DBMS: MySQL? What makes it noteworthy is that a year after Sun brought MySQL in 2008 for a billion dollars, Michael ‘Monty’ Widenius, MySQL’s founder went his own way and started his own fork of the DBMS. Today, we know that fork as MariaDB.

On December 4th, Red Hat announced the release of the next beta for its flagship operating system, Red Hat Enterprise Linux (RHEL) 6.4 is now available. According to the company, the release includes a broad set of updates to the existing feature set and provides rich new functionality in the areas of identity management, file system, virtualization, and storage as well as productivity tools.

While still primarily a server operating system RHEL 6.4 is designed “for optimized performance, stability and flexibility to cater to today’s diverse workloads running in physical, virtual and cloud environments.” The shipping version of RHEL 6.4 is due out in the first quarter of 2013.

Perhaps RHEL 6.4 most significant improvement is that it will include Microsoft’s Hyper-V Linux drivers.These will improve RHEL’s overall performance on Microsoft Hyper-V and enable Microsoft Azure users to run RHEL 6.4 as persistent virtual machines.

Apple TV and iTunes update news for cord-cutters

Setting aside the fantasies of Apple rolling out an Apple TV with a 40″ screen, Apple has been making some small, but significant, improvements in the mark 2 and 3 Apple TVs (ATV) with its latest 5.1.1 firmware update, and with the iTunes 11 release. 

The good news is that with the recently released Apple TV 5.1 firmware upgrade you’re able to use AirPlay to send audio content to AirPlay-enabled speakers and devices and use your ATV with multiple iTunes accounts. With the even newer 5.1.1 you get support for the Up Next option which gives you greater control over your musical selections. The bad news? Installing either or both is a pain in the rump.

Shimming your way to Linux on Windows 8 PCs

Getting Linux to boot and install on PCs locked down with Windows 8’s UEFI (Unified Extensible Firmware Interface) Secure Boot is still a major headache. However, Matthew Garrett, a well-known Linux developer who’s been working on fixing the Secure Boot problem, has just released a working UEFI boot solution for Linux distributors. This should enable many more versions of Linux to run on Secure Boot-imprisoned PCs.

Garrett, formerly a Red Hat programmer and now a security developer at Nebula, an OpenStack private-cloud company, announced on November 30th that he was “pleased to say that a usable version of shim is now available for download. … This is intended for distributions that want to support secure boot but don’t want to deal with Microsoft.”

This approach is not the same as the one that Garrett devised for use with Fedora Linux. That approach uses a Fedora-specific key that’s based on a Microsoft/Verisign-supplied Secure Boot key.

While that meant dealing with Microsoft, it was as Garrett had written earlier, “Easy enough for us [Red Hat] to do, but not necessarily practical for smaller distributions.” It’s also, as The Linux Foundation has found, in its so-far failed attempts to obtain a universal Secure Boot key for Linux distributions, really not that easy at all.
