On August 26th 1991, Linus Torvalds released Linux in the comp.os.minix newsgroup:
Hello everybody out there using minix -
I'm doing a (free) operating system (just a hobby, won't be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I'd like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).
I've currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I'll get something practical within a few months, and
I'd like to know what features most people would want. Any suggestions
are welcome, but I won't promise I'll implement them 🙂
PS. Yes - it's free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that's all I have :-(.
The creation of Linux was possible thanks to the Socialist system in Finland that provides free unlimited University education to its students, where Linus Torvalds was able to mess around with his own personal ideas for 8 and a half years for free:
Some talk by Linus Torvalds about Linux 10 years ago on the Charlie Rose TV show:
While Linux totally dominates in your smart phone (Android), in your TV/set-top-box, in the worlds servers that host all websites, in powering Government and Industry infrastructure, I believe that with Chrome OS and OLPC we are also soon likely to see Linux dominate for the home and enterprise desktop/laptop OS ecosystem.
x86 is becoming more and more problematic for Laptop makers as the retail prices are lowered, component and manufacturing costs remain high, profit margins are lowered and the overall Laptop market growth is being slowed by consumers using gradually more and more of their consumer electronics budgets on ARM Powered Tablets and Smartphones instead of x86.
Acer's previous CEO got fired about 3 months ago as their board of directors were angry at them not investing enough of their potential into releasing more ARM Powered devices, those that can maximize profit margins and enable real growth.
The big question for this ARM Powered Acer Laptop is to know if this will run the Tegra2, does that provide enough memory bandwidth for a good multi-tab web browsing experience, if they somehow have been able to provide a version of the 1Ghz Tegra2 with more memory bandwidth for Laptop use, or if performance is simply going to be similar to the awesome ARM Powered Toshiba AC100 released last year.
The news arrives by way of company chairman and CEO J.T. Wang as he addressed concerns about the company dropping from the second world's largest PC manufacturer to the fourth largest during the second quarter of 2011. He said that to regain its lost market share, the company plans to adopt a new strategy to create "more value instead of pursuing volume growth."
This is Awesome! ARM Powered Laptops are CHEAPER, use much lower power, thinner, lighter, would be perfect in a $199 ARM Powered Acer Chromebook, this is a perfect way for Acer to introduce something new to dominate a market.
Finally, instead of simply pushing out x86 powered reference design laptops based on Intel and AMD x86 chips, now Acer is investing to differentiate, improve, optimize, customize and design awesomeness through ARM Powered laptops that run embedded software.
Acer is not the only one!
Last month, Digitimes reported that Several vendors plan to offer ARM-architecture notebooks.
Several vendors, including Samsung Electronics, Toshiba, Acer and Asustek Computer, plan to develop ARM architecture notebooks, with products possibly to be launched as early as the end of 2011, according to industry sources.
Samsung may release Exynos 4210 Powered Chromebooks! Toshiba is probably doing an AC200! Asus is also rumored to be preparing a 13" ARM Powered Android Laptop similar to its Asus Transformer!
Look forward to A LOT of FUN TIMES ahead in the ARM Powered Laptop market. Which ARM Processor with how much memory bandwidth and which software OS would you like to run on your next ARM Powered laptop?

Discussion with Linaro employees about the status of ARM Powered laptops.
This is the Ubuntu In-Vehicle Infotainment system, using Ubuntu in the car. This is touch screen UI optimized version of Ubuntu.
Here is the board for now, they are going to launch the new Genesi i.MX53 based Laptops and Desktops around July or August, providing more performance, using lower power, at lower cost. The current Genesi Efika MX Smartbook i.MX51 based laptop is selling for $199, the Genesi MX Smarttop i.MX51 Desktop is selling for $129, they plan for the next generation i.MX53 based Laptop (Smartbook) and Desktop (Smarttop) to be sold for even cheaper. They are also working to combine their ARM based Laptop with the Pixel Qi screen as soon as it's mass produced.
Also watch my video interview with Konstantinos Margaritis talking about the way Genesi is optimizing Linux on ARM to make it up to 300% faster on these ARM Powered laptops and desktops.
Konstantinos Margaritis is a Senior Software Engineer at San Antonio based Genesi, he talks about how Genesi is pushing Linaro forward to recompile all the apps and everything around Linux to use hard float, to re-optimize floating point applications on ARM Powered Desktop/Laptop designs. Watch this video interview to find out how Genesi is doing these software optimizations on Debian for the i.MX51 and i.MX53 platforms in their ARM Powered Smartbook designs. How soon are ARM Powered laptops going to have enough performance optimizations in them to demonstrate that ARM is fast enough to power Desktop/Laptop designs so that every consumer can be satisfied with the performance?
iWave Systems makes Freescale based PCB designs and software optimization.
Canonical shows their new standard user interface. What do you think about Ubuntu's Unity interface?
Cupp Computing is now launching as a product their module to replace the hard drive in any Laptop, add an SSD, up to 2 MicroSD cards (one for the ARM Powered OS of your choice), and with a keyboard shortcut you instantly go from the ARM Powered OS to the x86 OS, and back while the x86 goes to sleep. The ARM Powered Laptop runs up to 40 hours on a battery, if you have just 10 minutes left of battery, switch to ARM mode and you've still got 1 hour of use to finish your work. In ARM Mode it can run Android, Ubuntu, Chrome OS and other. They are currently using OMAP3, they can use OMAP4 also soon for more ARM Performance. They also plan to work with motherboard manufacturers to add the whole ARM Powered laptop module right onto all motherboards so ARM Powered laptop mode becomes a default option in all laptops.

They say that they can make a 2Ghz ARM Cortex-A9 Dual-core now, but for now they are demonstrating it at lower clock speeds on an Android tablet, an Ubuntu laptop and an all-in-one Ubuntu 11.4 desktop example.
