The future of music industry is even darker – teraflop performance will open an on-thy-fly generated music era

Filed under: best_practices — natiku @ 6:45 pm

I am, as most of you mainly user of consumer oriented music, not an Audiofill – I am not listening music in HIFI quality just for pleasure to listen to it. Instead most time I use music as proper background noise to setup right atmosphere during my work or during for example my exercises to a lost little weight. In work I like on morning a slow symphonic music and after lunch more faster rock with more drums and guitars, during exercises I like some sort rhythmic one.

Sometimes ago I have chat with my friend musician about coming mainstream new graphic cards with magical teraflop performance and what new to do with them. He was excited about new sounds effects he can probably in near future generate with them and I was excited about genetic based algorithms progress (Sees GECCO conferences).

We were tinkering about this idea a little and as a result we have this vision:

“When you will have need to just consume music you will download a program which will generate music using genetic algorithms on-the-fly directly on your PC. You will be able to select type of atmosphere you want to have and you will be able to grow your music using many tune parameters to more fit your ears – you will be able to play with you music.

But most interesting will be then after you will grow your music you will be able to export your music as just mathematical model and share with friend or even sell it

Be open, isn’t will be very exciting to be able grow your MUSIC at FarmVille ?

Soon a VOCIAN language project will start, adding Genetic Singer Voice to Genetically Generated music. VOCIAN will be synesthetic language where words are sound nice when singed, but they will don’t have any meanings plus generated singing will sound natural to you despite what is your native language is.

Later various Neuro* groups will see a commercial potential , they will monitor your mood and will tune generated music to help you BETTER perform at work and be less tired when you leave it. They will also develop a learning mode helping you learning more effectively. But this will have terrible site affect – computes will be now monitoring you with build in sensors in your headphones.”

Today is day of boycotts against planned in US SOPA legislative targeting also a music piracy, here is my 5 cents:

Hi music industry, wake up, may be you are fighting with wrong enemy?

12minutes: Chromium OS FAQ: Evaluating in Virtualization QEMU/KVM, VMware and Virtualbox

Filed under: 12minutes, best_practices, ChromeOS — Tags: , — natiku @ 4:13 pm

12 Minutes: Chromium OS Procedure for creating virtual images change recently, so here is my steps:

Last Updated for: 0.9.85 2010/10/16 1739

Chromium OS use embedded design with focus on small amount of platforms – boards.
If you don’t have compatible with Chromium OS , Virtualization can be a vital alternative.
Chromium OS is for a 32bit OS so you can probalyl run it OK on wide range of Virtualization platforms.

Many evaluators are surprised them Virtualization Tools from concrete platform can’t be installed on Chromium OS due to embedded design with Read-Only Root approach.

1. Virtual Images are now created inside of chroot


cd ~/chromiumos/src/scripts/

repo sync

 ./ --help
  This script must be run inside the chroot. Run this first:

(cros-chroot)$ ./ --help
USAGE: ./ [flags] args

12minutes: Installing Ubuntu 10.04 LTS for regular Chromium OS compiling and HW test

Filed under: 12minutes, best_practices, ChromeOS — Tags: , — natiku @ 2:45 pm

12 Minutes: Chromium OS To build a Chromium OS yourself you need a 64bit Linux OS, I also try Fedora 13 64bit, but for this 2 reasons I stick with Ubuntu 10.04 LTS

1. Because most developers are use a Ubuntu
2. Because kernel in Chromuim OS is based on Ubuntu LTS source tree

Installing Ubuntu Desktop 10.04.1 LTS 64bit

Having very similar kernel can help me in way, then I can troubleshoot all HW issues in Ubuntu directly,
for many debugging tasks I will need a GUI so this is why I choose Desktop version.

I use a default installation of Ubuntu Desktop 10.04.1 LTS 64bit

For regular building Chromium OS I create a dedicated partition as /buildarea (you need keep in ming then Chromium OS images have couple GB each) and I make SWAP on third partition,
because Chromium OS build setup put on third partition root file system by default,
so this setup preventing me from incidentally start Ubuntu root from Chromium OS kernel.

sudo fdisk -l /dev/sdb

  Disk /dev/sdb: 80.0 GB, 80026361856 bytes

  /dev/sdb2              44G   21G   22G  49% /buildarea

Looking what HW we have on my build and evaluation machine

I use a single HW for Chromium OS building and evaluation Used $250 HW for compiling and evaluation of Chromium OS – on Single Machine, so here is some information about this HW from Ubuntu:

12minutes: Chromium OS FAQ: VMware ESX is not supported by default kernel ?

Filed under: 12minutes, best_practices, ChromeOS — Tags: , — natiku @ 8:50 am

12 Minutes: Chromium OS Based on discussion in chromium-os-discuss looks like there is not all needed drivers included in default x86 board.


I was hoping to run it directly on ESXi 4.1. I’m sure I can start with any VM format that works and convert it with vCenter Converter as needed.


I was preparing some OpenSolaris JeOS based images for variety of formats including ESX 3.5 so here is my 2 cents:

First issue (if I remember it correctly and is still valid for ESX4.x). ESX don’t support IDE based disks as VM storage and virtual ide controller is only used for CD, so I think then main issue here will be then vCenter Converter will convert disk to SCSI type, but Chromium OS don’t have needed SCSI driver (drivers are reduced to get smaller and faster images).

Second issue can be change in changed CHS mapping, I saw past sometimes during IDE – SCSI conversion changes in CHS geometry so some Linux VMware player images with GRUB legacy don’t boot after conversion due this.

Yes, true is Chromium OS use as legacy loader Syslinux 3.x and GPT which protective partition by definition ignore CHS (and partition boot flag), but on some BIOSes this combination make strange thinks from simple not booting to even system just hang right after you plug drive in !

Here is all needed VMware drivers in Linux(Gentoo) Gentoo VMware Guest

VMware LSILOGIC need Fusion MPT driver in Linux

I see in todays default Chronium X86 kernel
“CONFIG_FUSION is not set”
See Linux kernel fusion

So there is SCSI disks support needed by USB disks anyway, but not needed LSI driver.

Trick is then Chromium OS today don’t use initrd, all drivers need to be in kernel so kernel size is limited by amount of included drivers, may be this is design decision because Chrome OS is to be produced per “device” ?

It can be easily tested in Desktop products when LSI (FUSION) driver is included:

1. Start original ide image in VMware Workstation in IDE mode, check if boot OK
2. Convert disk to SCSI and move it to LSILOGIC SCSI adapter
3. Start converted SCSI image in VMware Workstation or Player

Is ESX 4.x finally supporting booting OS from IDE disks ?

Yes, IDE controler is there in ESX and you can connect Virtual CD-ROM there.

Unless is specially stated somewhere is ESX 4.x release notes as new feature, IDE disks are not supported in ESX due to poor IDE perfomance and scalability, but it can work for it.

From VMware vCenter Converter Standalone 4.0.1 Release notes:

What’t new
– IDE support
— Support for vSphere 4.0 as source and destination targets:

From ESX 4.0 release notes:

An IDE hard disk added to a hardware version 7 virtual machine is defined as Hard Disk 1 even if a SCSI hard disk is already present
If you have a hardware version 7 virtual machine with a SCSI disk already attached as Hard Disk 1 and you add an IDE disk, the virtual machine alters the disk numbering. The IDE disk is defined as Hard Disk 1 and the SCSI disk is changed to Hard Disk 2.

Sou you can try change disk type on converted disk manually back to IDE, reattach it as IDE and try it.

Converting a virtual IDE disk to a virtual SCSI disk

PS: I am working on x86 Chromium OS DEMO prototype where one image can be used for various IDE disk based virtualizations and direct usb boot with GRUB2 loaded and GPT protective partition converted to comply also CHS mode.
I will use as legacy boot loader GRUB2 because in will allow better debug various issues and it has better old BIOSes compatibility.

12minutes: Chromium OS Internals: How to start X application = Using aterm to copy outputs directly to blog ?

Filed under: 12minutes, best_practices, ChromeOS — Tags: , — natiku @ 8:01 pm

12 Minutes: Chromium OS Devel version of image have installed useful tools like aterm which is running under X ,
so we can copy commands and their outputs directly to Blog opened in Chrome Browser.

Get to shell first


You now have text terminal with X session

   screen 0: i915
xdpyinfo | grep visual: | wc -l

Start aterm in background with scroll back buffer 99000 lines and exit shell

 aterm -sl 99000 &

12minutes: Building Chromium OS image in 12 steps on ATOM nettop HW using REPO

Filed under: 12minutes, ChromeOS — Tags: , — natiku @ 7:02 pm

12 Minutes: Chromium OS Here I will like to share my experience compiling and building Chromium OS image on
relatively low power ATOM netbook or nettop like HW using new REPO command.

Chromium OS is 32 bit system, but you need a 64bit Linux system to build it on,
you can also utilize tricks for low power systems bellow on old 64bit Duron/Athlon with similar power of my nettop like
1.6Ghz ATOM 230 and D510 configurations

Here is my 12 steps for Compiling and Building Chromium OS USB Image:

12minutes: Which compression is best for sharing Chromium OS images ?

Filed under: 12minutes, ChromeOS — Tags: , — natiku @ 6:47 pm

12 Minutes: Chromium OS Which compression is best for sharing Chromium OS images with my friends?

Motivation – Most my fiends have strong download size limits

Well, in Europe is common then you have from one hand relatively fast DSL connection, but from other hand you have strong monthly transfer limits in size of single gigabytes. In this situation each megabyte counts and if I wont to share my Chromium OS images with friends which don’t have time to compile itself (or even don’t know how to do it) i need to focus on possible size savings.

Various compression of default Chromium OS image

I use for it this comparison my Chromium OS development system based on Intel Atom Used $250 HW for compiling and evaluation of Chromium OS and my previous experience with OS compressed images like Mapping possible Space and Time savings by using SMP aware (threaded) compression Utilities ? or Compressed ZFS Stream sizes in various compressing programs and OVF

Also some Intel Atom platforms compression benchmarks can be useful:

Intel Atom N550 vs. N450 : 7Zip Benchmarks, Dual Core vs. Single Core PineTrail Fight

NOTE: Chromium OS encrypt sensitive user information!

Compressing a file after encryption is inefficient. The ciphertext produced by a good encryption algorithm should have an almost statistically uniform distribution of characters. As a consequence, a compression algorithm should be unable to find redundant patterns in such text and there will be little, if any, data compression. In fact, if a data compression algorithm is able to significantly compress encrypted text, then this indicates a high level of redundancy in the ciphertext which, in turn, is evidence of poor encryption.

So already used (after login and browsing) Chromium OS image can be much larger then default one you get right after build process.

Measuring various compression of default Chromium OS image

Uncompressed size of default right after Chromium OS images is 1802MB, what minimal compressed image I can get ?

12minutes: Used $250 HW for compiling and evaluation of Chromium OS

Filed under: 12minutes, ChromeOS — Tags: , — natiku @ 7:58 pm

12 Minutes: Chromium OS My Configuration of used $250 HW for compiling and evaluation of Chromium OS

Motivation for Chromium OS Compiling

Some time ago I was participating in Web Kiosk project based on Linux and low power VIA Epia platform, it just launch Web browser (Firefox) in X and was controlled by touchscreen, we use Gentoo to be able quickly build customized fully manageable systems. Chromium OS project also using a Gentoo ebuild system, so it will like to evaluate whole Chromium OS building process too.

Motivation for Single Evaluation system

I share my big computer with my family, so I will like to have dedicated system for Regular Linux Desktop, Chromium OS and Jolicloud evaluation, which can also build and update Chromium OS over night regularly.

Motivation for used parts

Main motivation surprisingly is not overall system price, but having system which is currently represent a MAIN STREAM of target user base – here Intel ATOM platform users.

My current $250 HW Expenditure Limitation !

I am now freelancer with very small free money, so I will try to keep budget on this project low as possible.
I am in Europe and used parts are here even cheaper because they don’t have 20% VAT (Value Added Tax)

Netbook, Nettop or Custom Intel ATOM system ?

Most supported platform in Vanilla Chronium OS are Intel Atom platforms with Intel Graphic cards, see Chronium OS – Developer Hardware


For about $199 I can get used Asus EeePC 901 netbook with 8.9″ screen, but unfortunately Chromium OS can build today only on 64bit Linux System.

Pity, first generation of netbooks based on Atom Diamondville platfrom have only single-core Atom N270 at 1.6Mhz but without needed 64bit support.

Integrated Nettop:

I can get for $300 used dual-core Atom N330 with Nvidia platform, it’s 64bit, but Nvidia ION is not supported by Chronium OS.

Plus integrated nettop’s are not upgradable same way as netbooks, so they are not good protection of my investment over time.

Custom Nettop (mATX):

To achieve greater flexibility in configurations we can have also custom systems based on variety of mATX (microATX) motherboards and cases.
Most of this systems are produced as Barebone systems (pre-assembled OEM units), but similar systems can be easily assembled directly from part.

Custom ATOM based netbook like system ?

I will start with First Intel Atom generation Diamondville N2xx and 2xx/3xx lines (Introduced in 2008), netbooks are single-core only.

So I will build custom system based on Atom 230 (1.6Ghz, 64bit capable) (now -> D510) on mATX sized motherboard with 2 disks
(one regular IDE for compiling and second SSD for Chromium OS evaluation) and 1GB of installed memory are really minimum,
this system will be closes to first generation of notebooks with single core Atom 270 based HW like Asus EeePC 901 or similar.

Later I will like to use a second Intel Atom generation Pineview N4xx and D4xx/D5xx lines (Introduced in 2010), netbooks will be also dual-core.

See more in 7 Facts About Intel’s Pineview and Pine Trail and New Intel Atom Pineview/Pinetrail slaps Nvidia

Benchmark: Intel Atom N550 vs. D510 vs. N450 – Pine Trail Platform Pineview CPU Battle !
Benchmark: Intel Atom D510 vs. N450 vs. D410 – Pine Trail Platform Pineview CPU Battle !
Benchmark: Intel Atom D525 vs. D510 vs. N270 – Pine Trail Platform Pineview CPU Battle !

Later on I can switch to next generation ATOM D525 1.8Ghz DDR3 like Gygabyte GA-D525TUD to match Asus Eee PC 1215N netbook.

So I now update to newer, but still used Atom D510 + MN10 1.6Ghz real dual core system Gygabyte GA-D510UD mATX motherboard.
I can use for it older cheaper used DDR2-800Mhz memories and current IDE disk, plus IDE / SSD disk will be on separate channels.
This system based on Atom D510 will better match upcoming Atom N550 based netbooks, with performance close to nettops.
Acer, Asus, Lenovo, Samsung, LG, MSI, Fujitsu or Toshiba promise netbooks based on new dual-core Atom N550 platform.

Anyway Nettop’s are also on target Chrome OS to work on tablets, netbooks, laptops and PC? and Chrome OS Nettops – Why Not?

Here is my custom Atom D510 based system for $250 partially from Used parts

The Best Job Is Daddys’s One – FreeHand Painting (Colored Big Stones)

Filed under: Daddy's Corner — natiku @ 7:36 pm

Until about 3 – 4 year age kids can’t really draw or fill, but is important to practice a FreeHand Painting which can help them to get practice.

It’s very important to practice this techniques on really large sheets of papers which can bring freedom.

But vital alternative can be a large enough 3d objects like stone or clay based flowerpot.

For this kind of paint we use an Tempera (poster paint) colors. !!!! Use only non-toxic ones designed to be used by kids. !!!

There is many Tempera like colors available, but really ideal is to use washable ones, which can be removed from kids closes up to 1 hour from application.

But anyway I recommend to get for your kid a special painting closes with plastic over the for this activities.

PS: On pictures you can see one really needed instrument – paper towels 🙂

It’s very important to practice this techniques on really large sheets of papers which can bring freedom.

For this exercise we use a large (around 1m2) sheets of cheap packaging paper, most are light or brown brown colors.

For drawing with fingers Fingerpaint you need a special colors, they are usually sold in sets, it’s enough to get basic set of 6 colors.
Kids are usually painting directly from packaging, so don’t get packaging too big otherwise kids will use much more color then is really necessary.
True Fingerpaint colors are made from culinary materials and are non-toxic, some of them even have certificate to be a non-allergic..

These techniques can be combined for example with gluing, here is sample of added HILLS.

Free Hand Finger Painting or even simple Stamping is good practical way to learn colors and their mixing.
