What was Google thinking!?

When I first read Violet Blue’s account of Google kicking some Google+ users out of their new social network, my first reaction was “What the he… heck Google! After due consideration, I’m no longer surprised though. In fact, I can see Google’s point.

First, Google said from the start that while “Google services … support three types of use: unidentified, pseudonymous and identified” when it comes to Google+, Google “requires you to use the name that you commonly go by in daily life.”

More specifically, Google states “To help fight spam and prevent fake profiles, use the name your friends, family or co-workers usually call you. For example, if your full legal name is Charles Jones Jr. but you normally use Chuck Jones or Junior Jones, either of those would be acceptable.”

Don’t Panic! It’s only Linux 3.0

Linux 3.0 is out and the big changes are… ah… well. Not much.

Linus Torvalds, its creator and lead developer had warned us that this would be the case: “So what are the big changes?”

“NOTHING. Absolutely nothing. Sure, we have the usual two thirds driver changes, and a lot of random fixes, but the point is that 3.0 is *just* about renumbering, we are very much *not* doing a KDE-4 or a Gnome-3 here. No breakage, no special scary new features, nothing at all like that. We’ve been doing time-based releases for many years now; this is in no way about features. If you want an excuse for the renumbering, you really should look at the time-based one (”20 years“) instead. So no ABI [application binary interface] changes, no API [application programming interface] changes, no magical new features – just steady plodding progress.”

Oracle acquires zero-downtime, Linux upgrade software

I may reboot my Linux systems once every six months. That’s great for my personal use and a small business. For an enterprise, that’s not good enough. Even twice-a-year reboots is twice a year too often for them. That’s why Ksplice, which enables running systems to update even critical files without rebooting was so popular when it came out in 2009. Now, Oracle has bought Ksplice, and it appears it will be keeping it services available only for Oracle Linux.

Ksplice, according to its developers, “enables running systems to stay secure without the disruption of re-booting. Specifically, Ksplice creates re-bootless updates that are based on traditional source code patches. “These updates are as effective as traditional updates, but they can be applied seamlessly, with no downtime.”

That’s quite a claim, but Ksplice works. I’ve tested it myself.

Big files, Fast Internet? Lion download speeds

My buddy Jason Perlow had a bad day. When he tried to download Mac OS X Lion’s 4GBs, he ran into an hour-and-a-half of online road-block. When the download finally did start though, he was able to download it, thanks to his 100Mbps Verizon Optimum Online Ultra connection in about half-an-hour.

So, which can you expect? An hour and a half of freeze or a relatively fast download? I say “relatively” fast because in a perfect world 4GBs on a 100Mbps connection should take about five minutes. To find out what other people were seeing, I did an informal, totally unscientific survey of my high-tech friends on Google+ and Twitter to see what their experiences were like.

And, the answer, if you’re lucky enough to have a real broadband connection, is: Fast.

Mono, open-source .NET for Android, Linux and iOS, lives on

When Novell’s new owner, Attachmate, announced that it was letting Miguel de Icaza, the founder and lead developer of Mono go, I assumed Mono, the open-source implementation of Microsoft’s .NET was a dead development platform walking. Even after de Icaza launched his own company, Xamarin, to keep Mono going, I had little hopes Mono would survive. Well, it looks like I was wrong.

Xamarin has convinced SUSE–Attachmate’s Linux branch–to give it Mono’s intellectual property. In return, Xamarin will provide technical support to SUSE customers using Mono-based products, and assume stewardship of the Mono open source community project.

In a statement, Nils Brauckmann, president and general manager of SUSE, said, “This partnership is a triple win–a win for SUSE, a win for Xamarin, but most importantly, a win for our customers, users and community. Our partnership ensures SUSE customers continue to get the best support possible, enables the bright team at Xamarin to achieve success in their promising new Where Novell & SUSE Linux goes from here venture, and provides continuity of stewardship for the Mono open source community project in the very capable hands of its most passionate evangelists.”
