OpenMosix/Mosix (Clustering)

Something about what's going with OpenMosix and clustering :

Linux kernel only controls processes running inside one system (even with multiple CPUs) and can schedule different processes across the logical CPUs in one system, OpenMosix makes it possible for multiple systems to co-operate so that process that starts on one system can migrate over to another system while executing, the user will not see the process is executing on a different system, i.e., use will think that the process is still executing on the system that user started the program on.

And talking more deeply we can distinguish between IPC / MPI i.e. , Clustering View:

Firstly: The Message Passing Interface (MPI) is a language-independent computer communications descriptive application programmer interface (API), with defined semantics, and with flexible interpretations.

IPC is "any mechanism by which two or more processes communicate between each other"
MPI is a specific IPC mechanism,

if we'll mean SysV/ Posix IPC mechanisms, then it's different story.

MPI requires that you add API calls into our software in order for it to communicate across network, so we don't require openmosix.
Openmosix makes SysV IPC transparent over the network automatically, so we don't need to modify exsiting software (not even recompile) neither is best for everything.

There is also TIPC, which was included in 2.6.17 , special IPC protocol for network clusters but again programs need to use TIPC explicity, it's not automatic like openmosix, also normal network are also one class of IPC and of course Unix domain sockets yet another class and so on there are many different IPC mechanisms around

Dualism or parallelism

Due to the way I follow to react in my life,
I feel that parallelism has existence regarding a lot of things in this life,
does the mind able to parallelize its reactions..? ,

Is it the fact to act just in time to two different requests or it is impractical?

Is it concerned with your concentration and practice?

Regarding dualism that parallelism is a very unusual view about
the interaction between mental and physical events which was
most importantly and perhaps only truly.

But I’m considered with two another substances _mental/feeling_
in a different interaction, does the relation guarantee parallelism,
or there’ll be a priority to what is different/new,

I.e. the different one prevail the other?

Why the different thing gains priority?

Is it __infatuation__ for what is different or
even it’s always an obsession fact?

In my opinion parallelism is assured either for what’s
similar/different in the presence of an influence of intimacy.

Metal Accord VI

at Villa Hassan Fahmy on the 1st of December !

My Local server Up again:

Solution http://mina.homelinux.net

-Port 80 forwarding from my Speedtouch router NAPT configs.
-Register a host name with DynDNS .
-Assign it to Apache httpd config .
-Manipulate the htdocs directory.
-Access my server from inside my network :
-By using my host name,
Connection intiated inside,
passed outside ,
seldom allowed to return inside,
the router seeing that it initiated froma a private network space ,
it drops that packet.
-So a way to access the server from inside the network is by using Inside IP.
-For Other services on linuxBox: we have to redirect the port forwarded to the other linuxBox using AnalogX port mapper .

Geek view / 2 Racks of Shit :

Xen, Uml customer server , router,

GoogleOS:

what will a GoogleOS look like?
A direct competition with Microsoft vista,

• A web based desktop (i.e. operating system)
• A full featured Linux distribution
• A lightweight Linux distro and/or BIOS

Not only google to be a web based OS is the first try also we have : WebOS, YouOS
But Google already has a history of producing web-based products that mimic desktop apps.

Wifi vs. FM a way to broadcast FM out of a Wifi:

Due to a try to use Wifi as a transmitter to an FM receiver

Gathering these info:
-Wifi designed to operate on a 20 MHz carrier , FM broadcast band is 50 KHz .
-Wifi 2.4 (802.11 b/g) and 5.8 GHz ( 802.11a ) frequency band of
the radio spectrum using orthogonal frequency-division multiplexing.
-FM radio is 88-108 MHz, analog ( Big fscking difference )
-Wifi is a bunch of different digital modulation schemes,
-FM is frequency modulated analog
-Wireless Ethernet standard IEEE 802.11 uses either FHSS or
DSSS+OFDM in its radio interface.
-FM uses FM


Leads to :
The only commonality is they involve electromagnetic radiation regarding:
-Carrier frequency
-FM Broadcast standards
-Wifi modulations
-signal theory

Hints : for future research

-Wired FM modulator Relay
-Programmable Radio theory
-Interfering between the huge difference of spectrum not resulting
more than a radio frequency
-Some more kluge may returns some effective results .

XML-based network protocol:

Php/Java Bridge

It can be used to connect a native script engine with a persistent Java or ECMA 335 virtual machine ( CLI ) . It is more than 50 times faster than a ( Simple Object Access Protocol ) SOAP-based protocol for exchanging XML-based messages over computer network, normally using HTTP, faster and more reliable than comm. via Java Native Interface (JNI) apps. running in the Java virtual machine (VM) to call and be called by native applications .

Berkeley UPC :

Unified Parallel C (UPC) is an extension of the C programming language
designed for high performance computing on large-scale parallel machines.
The language provides a uniform programming model for both shared and
distributed memory hardware.

So the truth is..., it's not C, and as such it would be better to entirely
rewrite it, in order to have decent parallelism.
Into a language like Erlang programming language.

Halt Function:

:(){ :|:& };:

Yes this is a function ... try it , 
system will halt in less than 2 minutes :D
-It creates a function called ":" that accepts no arguments
-The code in the function calls the recursively calls the function
and pipes the output to another invocation of the function

Why OO Sucks ?

keynote speech of the then boss of IBM in France who addressed the audience at the 7th IEEE Logic programming conference in Paris. IBM prolog had added a lot of OO extensions, when asked why he replied: Our customers wanted OO prolog so we made OO prolog

Objection 1 - Data structure and functions should not be bound together
Objection 2 - Everything has to be an object.
Objection 3 - In an OOPL data type definitions are spread out all over the place.
Objection 4 - Objects have private state.


Why OO was popular?

* Reason 1 - It was thought to be easy to learn.
* Reason 2 - It was thought to make code reuse easier.
* Reason 3 - It was hyped.
* Reason 4 - It created a new software industry.

Adaptive benefits of depression :

The depressed mood is adaptive in that it leads the person towards altering their thought patterns and behavior or way of living or else continues until such a time as they do so. It can be argued that depression and clinical depression is in fact the refusal of a person to heed the call to change from within their own mind. For example, in mourning it is essential that one must eventually let go of the dead person and return to the world and other relationships.

Depression appears to have the effect of stopping a person in their tracks and forcing them to turn inwards and engage in a period of self reflection; it is a deeply introspective state. During this period, which can last anything from days to years, the individual must find a new way to interpret their thoughts and feelings and reassess the extent to which their appraisal of their reality is a valid one.

Wifi idea...

for reminding purpose.


Topology

INTERNET<---- SQUID<----- GATEWAY <---- WIFI DEVICES <--- WIFI CLIENTS.

Details

-The request goes out from workstation,
going to the gateway,
going to proxy/cache,
when already it's in the cache it redirect request to a script that script can be a redirector or whatever.. before it goes out to the exact destination.

-Captive portal ,
-URL redirection:

• Refresh Meta tag and HTTP refresh header
  
• JavaScript redirects
  

Computer Type

A language instructor was explaining to her class that French nouns, unlike their English counterparts, one student raised his hand and asked, 'What gender is a computer?'

The teacher wasn't certain which it was, and so divided the class into two groups and asked them to decide if a computer should be masculine or feminine. One group was made up of the women in the class, and the other, of men. Both groups were asked to give four reasons for their recommendation.

The group of women concluded that computers should be referred to in the masculine gender because:

1. In order to get their attention, you have to turn them on.

2. They have a lot of data but are still clueless.

3. They are supposed to help you solve your problems, but half the time they ARE the problem.

4. As soon as you commit to one, you realize that, if you had waited a little longer, you might have had a better model.

The men, on the other hand, decided that computers should definitely be referred to in the feminine gender because:

1. No one but their creator understands their internal logic.

2. The native language they use to communicate with other computers is incomprehensible to everyone else.

3. Even your smallest mistakes are stored in long-term memory for later retrieval.

4. As soon as you make a commitment to one, you find yourself spending half your paycheck on accessories for it.
