Puppy linux from PC to mainframe ARM architecture ? How ?

PC is designed as a terminal to connect to mainframe computers. It has all kind of peripherals and buses legacy from the early days.

Today a mainframe computer can be designed with USB bus; you need cpu(ARM) and memory(flash). WiFi connection can be done using SanDisk flash memory. Virtual Wifi network already has many free hotspots(public places).

To make the mainframe computer design usable as a terminal, you need a GPU for video display of mpeg4/h.264 webpages. And you need data input device even speech microphone and speakers. of course people are using touch screen which is not comfortable as keyboard.

So, the Linux stack of software has to be modified. Kernel will setup console with gpu and keyboard, then boot the system. connect with wifi network and display browser workspace. Desktop gadgets will occupy some workspace of the browser.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Smartphones with 3/4G uses ofdm, which is very slow at 0.5 mbps or 65 kBps speed of transmission.

Wifi/b uses DSSS mode and can go up to 900 kBps or close to 11 mbps.

So, most of the ARM smartphones are too slow for internet video streaming. Now a days tablets are all wifi/n but still 65 kBps with ofdm mode. This mean the Raspberry pi motherboards if manufactured has not much hope of being used for video streaming. One without network(SD formfactor with USB micro connector), one with ethernet(no wifi/b) and two usb ports instead of one. Some one will have to supply a usb hub of a touch screen docking station.

The Raspberry project started not by having motherboards made by ARM manufacturer. So they are gambling with inexperienced people to make motherboards that ARM cpu might be like Snapdragon. Not many people can use the cdma flexibility. Which is in some way like linux file switching. Too many monolithical files to be shared but the flexibility of crossover to other files creates too many possible bugs.

So, Raspberry pi had not yet been released for purchase. The cheaper one is a mainframe computer design. to be plugged into a touch screen docking station as a terminal connected by wifi/b. The expensive one has ethernet network for development tied to workgroup network with hdd and printer.

Eventually Raspberry pi will be a hobby community to work on embedded discrete devices. But a tablet of many parallel pi mainframe computers can be a powerful tablet design.

To use USB to add parallel cpu wth memory makes multicore computer design easy.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Operating system(ARM tablets) Microsoft had for windows8 is metro schemed.

Basically it is html5, css and realtime operating system in each webpage.

From the codec you know its all webpages(on desktop apps too) to upload and download data from data center servers.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Arch Linux ARM can not do GUI because dram limitation of 256 mB on Raspberry Pi.

32 gB of flash rotating memory is needed to do GUI in rolling release of Arch Linux ARM.

Swap file of 2 gB is needed to support lack of drams for all Linux distros.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Puppy woof now has 256 mB of drams in the install script for better handling of Linux kernels. However it still needs hdd or USB key for swap file. Linux really needs 512 mB if Firefox browser or Chrome browser is used.

This is because of not using squashfs(128 mB) to shrink dram requirement. People think squashfs is slow, but some computers or laptops did not allow more memory installed for modern Linux architecture.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

If you follow Barry's blog on Puppy Linux; it is all about the operating system and how to install kernels and packages. Woof, racy and others.

But the overall direction is still file manager oriented. We have moved to browser oriented operating system, 5 years ago. WiFi connects to internet on boot up. Browsers give us autoupdate from some repository. And Facebook give us apps and games using Adobe v11 on XP. Its now website centric, no more desktop centric all by yourself.

Windows8 is now metro bus or train to internet websites. All apps operate from webpages. Cable TV can now have interactive TV games or apps.

If your life is Puppy development, start programming webpages? Or be able to use Dillo and SeaMonkey to get website apps, strip out all the desktop stuff, including graphics. Browser workspace can be prettied up.

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

For Arm cpu, Linux kernels had to be stripped down from Intel introduced functions and drivers. We are back to GCC v3.4 for Arm v11 or v6. GCC v4.5 and 4.6 are not upto date to run TI, Qualcomm and Nvidia Arm cpus.

Raspberry Pi circuits are 3 years behind in technology(2006-2008). It has only thumb(16 bit branch prediction).

You can waste a lot of time on the past, like I waste time on W95/98SE with WiFi/b. Or spend time to load W2k(4 hours with sp4) on old laptops. But the minute you get on Facebook, you can see a different kind of portal to keep up with your family or friends. Then you can also amuse yourself with new apps and games.

Its a different world not like Yahoo or MSN.com(portals). You can sort things out on many portals?

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Puppy now tries to learn from Ubuntu precise version(apple oriented speed dialing) to keep up with linux kernel development and cross over to ARM platforms of mobile devices.

That means pickup unity desktop apps? Or use browser extensions for apps? This avoids using android browser operating system architecture. Ubuntu has android cellphone connection for Firefox browser.

But Ubuntu is slow migration to smartphones big data processing. Servers application is data transfer virtualization(virtual servers). Not really desktop apps. More search engine replies on browsers.

The data delivery technology is still merging into browser operating system(wifi preferred).

Ubuntu TV is the future rich experience of big data(millions of webpages) with or without Dolby mobile sound but interactive TV?

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

While learning from ubuntu kernels can help developers, it is not enough to use their repository for update. Ubuntu update is auto announced for you to update by internet connection. You don't get update if on desktop only.

So, putting ubuntu into puppy is a wish for messy operating system. Neither fish  nor fowl.

Ubuntu 12.04 is now more smartphones than desktops in the future. More like Apple tablets than Linux?

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

So, Puppy is going with Raspberry Pi, but when will they deliver?

Puppy couldn't do ARM development boards, they are for code debugging.

Puppy is now trying Mele settop box with ARM A10 cpu.

You can see the problem of not having hardware that can do big data download with rich experience delivery. This is now wifi, mpeg4/h.264 in hdmi monitor and small speaker big Dolby mobile sound. Linux kernels had to be stripped down to these bare minimum codec, but you still have to find the hardware not likely in embedded system manufacturers' catalog.

HDD is replaced by SD cards. PCI bus is now USB bus.  Desktop apps is now webpages of apps. Have fun, move on?

$79 tablets and netbooks however will need an operating system to replace the technically deficient operating system of last few years? This means a small operating system to be downloaded to the tablet or netbook, then install it in place of the older operating system and cleanup the old operating system. Not an easy task?

Grub for a partition for the new operating system, then boot it and clean up the old partition, use it for data storage and system restore or reset(like f11 in newer laptops).

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Mainframe architecture is timeshared serial ports(today its USB ports).

PC architecture is peripheral assignments to ports by bios detection.

The difference is great, and not interchangeable. ARM cpu is not yet planned for 127 USB ports for multitasking timeshare data processing. But periperals are now able to be assigned to a USB port?

Linux kernels has not yet worked out the USB ports for 127 devices or data connection to websites through speed dial switching.

It may take another two years before Linus got wise to the difference in architecture?

Re: Puppy linux from PC to mainframe ARM architecture ? How ?

Tiny Linux are for older computers with older cpus. The main deal is get on internet. which now means wifi connection. You have to find wifi usb or pcmcia devices that they included linux drivers. The good old prism drivers for orinoco wifi is now not connectable to 50 mbps cable systems.

You might try Ralink usb wifi devices 2870 for their linux drivers. Dlink also has usb wifi linux drivers.

It seems that USB wifi has more support from Linux community not pcmcia wifi devices which was mostly Linux /b drivers.

ARM devices are not wifi friendly, they are mostly 3/4G connections to take advantage of the data compression ability of ascii code compression.
