Canalys On Wintel

‘The combination of ARM-based chipsets and Android has taken computing devices to new, lower price points. If Microsoft and Intel are serious about capitalizing on this exploding market, both will need to ensure that their OEMs can remain competitive on price.’
see Smart mobile device shipments exceed 300 million in Q1 2013

More than a decade ago, M$ was worried when the price of an ATX PC box was ~$1K. Well, that capability is now available for ~$100. It’s time to rethink everything. Trying to raise the price of PCs as “Ultra”-somethings won’t cut it. Even an ARMed smartphone is absolutely wonderful… Trying to spread FUD won’t cut it as even the consumers on the street and the news media can see that the emperor has no clothes. Remember, every middle-aged user on the Earth has seen enough BSODs and malware to last a lifetime. Now that they can see a price-difference between Android/Linux on ARM and Wintel, large numbers are choosing the less costly and better-performing option.

If you want an alternative to Android/Linux or M$’s OS on your PC, consider Debian GNU/Linux, “the universal operating system”.

KVM Updates For Linux 3.10

I use KVM (Kernel-based Virtual Machine) a lot and it works pretty well for most purposes. Apparently I am not alone for updates in the pipe at kernel.org are many and with a large number of contributors:
“KVM updates for the 3.10 merge window. Highlights of the updates are:
general:
– new emulated device API

– legacy device assignment is now optional
– irqfd interface is more generic and can be shared between arches
x86:
– VMCS shadow support and other nested VMX improvements
– APIC virtualization and Posted Interrupt hardware support
– Optimize mmio spte zapping

And many other bug fixes, cleanups and improvements.”


see LKML: Gleb Natapov: [GIT PULL] KVM updates for the 3.10 merge window

I count 37 contributors of more than 200 patches. KVM appears to be thriving. I think I will upgrade some of my systems to Linux 3.10.x shortly.

That Other OS An Also-Ran In Q1 2013 Tablets Shipped

By this time next year, Android/Linux will be the giant of tablet OS.
Tablet_OS_1Q2013

It’s not just the current performance that matters. It’s the growth rate, 247% year over year. iOS with a much smaller share has growth of only 65%. That other OS has a spectacular 700% growth rate, but even if they could duplicate that this year, they would have a smaller share than iOS…

This comes after M$ pulled out all the stops and dictated how UEFI would work and spent hundreds of $millions on advertising. They could not even come close with all their restrictions and leverage. In the last year, the monopoly has died. There are just a few retail shelves to be swept clean of M$’s OS. By next year, */Linux will be swarming all over and M$ will have to pay people to listen.

Android/Linux Saves Lives

To infantry, the sniper is hated, unless he’s working for you. A single shot is enough to kill at extended ranges and it’s almost impossible to locate a sniper from that one shot unless…
“You are walking down the street with a friend. A shot is fired. The two of you duck behind the nearest cover and you pull out your smartphone. A map of the neighborhood pops up on its screen with a large red arrow pointing in the direction the shot came from.

A team of computer engineers from Vanderbilt University’s Institute of Software Integrated Systems has made such a scenario possible by developing an inexpensive hardware module and related software that can transform an Android smartphone into a simple shooter location system.”
see Tracking gunfire with a smartphone .

Yes, there’s an app for that. Combining the GPS, timing and audio-processing available in Android/Linux, the problem comes down to maths and geometry. So, Android/Linux does save lives.

- Robert Pogson

and So It Came To Pass

Sometimes I get things right. Last year, I predicted that 2013 would see lots of */Linux notebooks shipped and sold.
(“I expect 2013 will see more widespread adoption of GNU/Linux as well as prices of desktop/notebook PCs plunge in order to compete on price/performance.”)
That appears to be a winner…“Expect to see Intel-based Android laptops and hybrids priced between, let’s say, $200 to $500 in the coming months. (Likely, at first, from companies such as erstwhile Netbook vendors Asus and Acer.)

It Pays To Advertise FLOSS

I have been noticing some ads for the Linux Foundation appearing on the web:
LF_ad

Such advertising is one of the things that is needed to generate demand for FLOSS everywhere. The Linux Foundation may get a deal from Google or they may be able to afford the price. We bloggers can help by providing links to various organizations and individuals producing FLOSS. Every bit helps.

BTW, in about a week, the new release of Debian GNU/Linux will be official and this blog runs happily on GNU/Linux operating system, Apache web server, MySQL database, PHP scripting, and WordPress blogging software and many others.

Why The Small Cheap Computers Are Changing Everything

From the user’s point of view the small cheap computers have huge advantages like price, performance, portability, and running FLOSS operating systems. Underneath that, in the chip itself is a magical combination that used to fill an ATX box with components. For x86/amd64 all of those components were managed well except the graphics which were closely guarded secret places where FLOSS was often second best because the manufacturers did not produce FLOSS drivers and were often not cooperative.

With the ARMed CPUs and integrated graphics on the chip in small cheap computers a FLOSS OS was often running on Day One. It no longer takes a year or so to “catch up” by reverse-engineering after release to market. The chip-makers are mostly members of the Linux Foundation and contribute “binary blobs” to load proper software for the Linux kernel and the particular GPUs. Combine that with devices like Raspberry Pi and Beagle Boards that are very accessible for all and the passions of developers to find out how things work and this happens:
“First off, after the RadeonHD project, it was clear that i did not want to waste further time on the x86 linux desktop. It’s a political swamp, where correct insights, hard labour, and actual results are all irrelevant if you do not belong to the right political group. And the lengths this group would go to to affirm their own supposed awesomeness shocked even me. The consolidation that happened in the x86 desktop graphics market, with the few remaining players now sticking hard to their respective position towards open source software, gives little option to do real work and achieve results outside of what is dictated by corporate politics. It was time to move to something new, and the completely level and open playing field of ARM GPUs was exactly that.

Secondly, when looking at the way the world was turning, everything was becoming ARM, and (almost) everything ARM was running some form of linux. There was only one key reason why people were not running a proper full linux on their ARM devices. One key factor that made this nigh impossible: binary userspace drivers. Someone had to get stuck in, prove that this is not beyond reach, and change this stalemate forgood. This was a perfect wall for running a very hard head into.

Finally, while I have covered most sides of graphics driver development in the meantime, I had not done any real 3D driver development before. When I was the only person who cared about boring modesetting, I often had to hear how difficult 3D graphics hardware is. Some part of me always knew that that was an excuse to not deal with the boring but highly important bits, but now I got to prove that this is not the case. If the hardware is sane, a 3D driver is sane as well, but even when the hardware is sane, the sheer number of combinations possible make display driver development impossible to get absolutely right for everyone. A few FPS less is not the end of the world, a display that does not show any image means that the user will turn and walk away. And it indeed was an excuse for not dealing with what people really needed at the time.”
see The SoC GPU driver interview – Architecture Logicielle & Développement

The result is we are on the verge of having complete access to graphics on the small cheap computers for every purpose, HPC, servery, auxilliary computing, and, oh yes, graphics in 3D. Since the graphics unit does most of the work in this, the ARM processor is out of the way entirely. Some of these units actually use the GPU to boot the SoC. How refreshing. Because of FLOSS users will now have all the performance of their hardware without limits by hardware manufacturers or “partners” of M$, small cheap computers have rapidly evolved to be on the forefront of innovation rather than being auxiliary computing devices.

From my point of view, that IT is best done without any involvement by M$, this is the best opportunity to escape bondage that we have seen in many decades. The world can make its own software cooperatively without any “help” from the slave-masters.

Galaxy S4 Exploding In The Market

“Samsung has claimed that it is likely to run out of its new Galaxy S4s and is facing overwhelming global demand.”
see Samsung claims it will struggle with Galaxy S4 demand – Caught off guard

Sheesh… I know a guy in the market for one of these. His old phone has a smashed screen but it still works…

It says something when a product built on FLOSS is limited only by the rate of production and the Chinese can’t supply enough. It’s the right way to do IT. No need to pay extra to get your hardware to do what it can… FLOSS works for everyone.

The New Lock-in

From early on M$ leveraged the lock-in of ISVs (“Independent” Software Vendors) and file-formats to keep customers plodding along the Wintel treadmill, having to replace PCs every few years while paying for yet another licensing fee. Lock-in works both ways:

  • Consumers and businesses are finding ever more ways to use small cheap computers not using that other OS. There’s a reason smartphones are moving to larger screens. People are actually using them for more than talking… Continue reading ‘The New Lock-in’

Linux Foundation Welcomes Three New Members

“The worldwide increase of Linux adoption in critical technology areas is reflected by the diversity of The Linux Foundation’s membership and in the ways those members use Linux. Hisense Mobile uses it to customize mobile terminal solutions. Solarflare uses Linux to support enterprise and web 2.0 customers who scale out computing in multiple applications, and Thomas-Krenn supports High-Performance Computing (HPC) and mission-critical enterprise workloads with Linux.”

Mobile thingies, servers, workstations… There’s just nowhere in IT that GNU/Linux doesn’t work for people. Why not put it to work for you?

IT In Kenya Evolves Free From Wintel

“The number of Internet subscribers increased by 75.1 percent in the quarter compared to same period in 2011.

The report indicated that mobile data/Internet continued to dominate the market contributing 99 percent of the total internet/data subscriptions in the country.

However, the number of broadband subscribers declined to 1,002,701 from 1,006,071 posted during the previous period, mainly due to a reduction in the number of fixed terrestrial broadband subscribers.”
see allAfrica.com: Kenya's Internet Users Hit 16.2 Million

What a difference a decade makes! Ten years ago, Wintel would have been the only way to go for the IT ecosystem but it was too expensive. Now Kenyans have the choice of small cheap computers running */Linux and are loving it. Wintel need not apply.

And It Came To Pass, Small Cheap Computers Rule The World

“Rumour loving Digitimes reports that several major vendors, including Lenovo, HP, Toshiba, Acer and Asus will launch Intel based convertibles sometime in the third quarter. Lenovo will lead the way and it will introduce its first Android based notebook a bit earlier, in May. ”
see Rumour: Intel reportedly pushing Android convertibles – Sorry Redmond, it’s just not working out…

Chuckle. You know the end of monopoly is near when it fragments and one half of Wintel throws the other half, M$, out of the lifeboat. When OEMs and retailers get behind */Linux the party will be at my house. ;-)

My Mission

My observations and opinions about IT are based on 40 years of use in science and technology and lately, in education. I like IT that is fast, cost-effective and reliable. I do not care whether my solution is the same as yours. I like to think for myself.

My first use of GNU/Linux in 2001 was so remarkably better than what I had been using, I feel it is important work to share GNU/Linux with the world. I have been blessed by working in schools where students and school systems have benefited by good, modular software easily installed in most systems.

I have shown GNU/Linux to thousands of students and hundreds of teachers over the years and will continue in some way doing that until I die in spite of the opposition.
