We are using zones here, we have only problems.
- unability to patch zones (we are using u3)
- performance problems (thanks to processes block in kernel mode).
- and now the servers reboot itself in u5
Solaris 10 is the most crappy release from Sun. You are taking Sun's blueprints/site like a reliable source. But it's only some ads from Sun, in fact the reality is by far different.
On the other side AIX and LPAR are working like a charm...

Thats interesting, as where I work is a primarily IBM site, and pSeries/AIX is the buggiest P.O.S I've ever worked on.
LPAR's are not totally separate, I've seen DLPAR operations on one LPAR kill another due to memory conflicts. We frequently see Power5 and 6 boxes drop when they suddenly offline 8gb of RAM, or decide to offline a cpu for laugh.
The IBM VIO server is memory and CPU intensive and prone to having strange issues which you just can't trace through its complicated configuration (why the hell is every network card enX on AIX???).
I guess its what you're used to... I work on AIX and yearn for Sun - looks like you're the other way around!

U3 is fairly old now.
- performance problems (thanks to processes block in kernel mode).
Can you elaborate on this please? Is there a bugid?
- and now the servers reboot itself in u5
bugid?

Can you point out which Blueprints are incorrect so
we can get them fixed please. It's also interesting
that you use this argument as a retort - did you
read the article linked by the OP? What would you call
that?

charm
⢠noun
1 the power or quality of delighting or fascinating others.
2 a small ornament worn on a necklace or bracelet.
3 an object, act, or saying believed to have magic power.
Seems somehow appropriate given the nature of your
post.

"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.

"Android and iOS, the number one and number two ranked smartphone operating systems worldwide, combined for 92.3% of all smartphone shipments during the first quarter of 2013 as Windows Phone crept past BlackBerry for 3rd place. According to the International Data Corporation Worldwide Quarterly Mobile Phone Tracker, Android smartphone vendors and Apple shipped a total of 199.5 million units worldwide during 1Q13, up 59.1% from the 125.4 million units shipped during 1Q12." Windows Phone doubles from a few to twice few, iOS loser market share as its growth is slower than that of the overall market. BlackBerry continues slide into irrelevance.

This article is riddled with fundamental inaccuracies. Most of this data has been available for over an year. Very poorly researched.
Scalability -- Only eight CPUs and 64GB RAM on one machine
Sun just announced a 4 chip UltraSPARC T2+ system that has 32 cores and 512GB Memory. Each core runs 8 threads. A domain can be assigned to each of these. So a 4-way UltraSPARC T2+ system can have 256 Logical domains.
http://www.sun.com/servers/coolthreads/t5440/
Sun also has T2+ chip based 2 way and have much larger memory configurations than 64GB.
http://www.sun.com/servers/coolthreads/t5240/
Low end and Midrange with the introduction of T5440.
CPUs can be dynamically added and removed ever since the first release.
http://www.sun.com/blueprints/0207/820-0832.pdf
"All CPUs exposed by the hypervisor are referred to as virtual CPUs. On
platforms supporting logical domains, such as a Sun Fire T1000 and T2000
system, each of the cores of the system has four executing threads, represented
as virtual CPUs by the hypervisor. Thus, an eight-core Sun Fire T2000 server
would have 32 virtual CPUs able to be partitioned between the various logical
domains on the system. With this release of Logical Domains 1.0 software, virtual
CPUs are able to be dynamically reconfigured; that is, removed or added to a
guest logical domain while the guest operating system is running, without
requiring a reboot. Note this requires a specific version of the Solaris Operating
System to be installed in the guest domain and might not work with other
operating environments.
"
You can have 32 domains on T1, 64 on T2, 128 and 256 on T2+ based systems depending on the configuration.
Sun's Logical Domains provides the exact same capabilities. Some how the author missed that while doing research as well.
What could have been a good comparison ends up being a typical IBM marketing FUD piece.
