Natural rendering!

Stefanos Karagos | September 17, 2007

I think that this is THE best renderer I've ever seen!

fryrender is the unbiased spectral renderer developed by Feversoft.

All the elements involved in the render (materials, lights, cameras, ...) are based on physically accurate models up to the point that when you hit render a simulation of the real behavior of light happens inside.

This not only leads to the finest quality true-to-life renditions, but also makes the engine very easy to use. Things just look the way they have to once your scene is set up.

Moreover, fryrender is the first engine of its kind capable of transforming scenes into a format that can be navigated in real-time with the aid of our Virtual Reality engine Random Control 4.

Please, take a look at their gallery....

Students, boost your performance!

Before months -after the huge success of my first brainwave- I had promised to create another one, and now the time just came!

The first sound [Brainwave] file that can improve your Studding performance is here!
[a WAV file into a compressed RAR file [175.3Mb], about 25' long]
THANX SENDSPACE.COM FOR THE FILE HOSTING

To use this session, simply find a quiet place to study and listen to this.
This brainwave file is ideal to use while performing complex studding tasks [for example studding for exams...]
It helps focus the mind while reducing anxiety and frustration.
Because this session presents separate stimulation to each brain hemisphere, headphones are required. It is important to make sure that you are use your headphones correctly: with the right side on your right ear, and left side on your left ear.
You may want to set your sound player to LOOP as well till you will finish your study session.
Also it is very important that you adjust the volume settings until you are 100% comfortable with the sound before starting.

Brainwave Entrainment's usefulness is not limited to relaxation and enhancing academic performance. It can also be used for reducing headaches, insomnia, stress and even enhancing athletic performance.

For more info about Brainwaves Entrainment please take a look on my previous post here.

Are you ready to boost your studding performance starting from your ...ears?


WARNING!
The following people should not use brain entrainment:
> People subject to any forms of seizures or epilepsy
> People using pacemakers
> People suffering from cardiac arrhythmia or other heart disorders
> People taking stimulants, psychoactive drugs, or tranquilizers

Fast ADSL without leaks

My latest discovery is a small program that is a really gem.
cFosSpeed, installs some new drivers in your PC giving you the ability to surf smooth even you are downloading in background tons of files ;-)
Using some "special" technics [like Traffic Shaping], cFosSpeed prioritize the data packets with a way that gives you full access to your broadband bandwidth.


cFos Traffic Shaping reduces delays during data transfer and allows you to surf the Internet up to three times faster. So you can use the full bandwidth of your connection!


During TCP/IP transfer, a certain amount of data needs to be confirmed upon reception before more can be sent. Stalling data confirmation results in delays and transfer-rate slowdowns, thus forcing the sender to wait. Especially for DSL and cable, it is possible to slow a download to a crawl by choking the upstream channel (which has the smaller bandwidth anyway) with an upload. This is because in such a scenario there is not enough upstream bandwidth left for data confirmation.


The standard solution so far has been to try and compensate for this by increasing TCP window size, thereby allowing more data to be sent without immediate confirmation. The main problem here is that this also leads to high ping times (latency) and significant delays during Webpage rendering. Latency of up to 2 seconds is not uncommon for TCP windows with a size of 64k. In short, huge window sizes just won´t let you achieve full download speed.


By contrast, cFos Traffic Shaping prioritizes data traffic in such a fashion that important packets zip past regular packets. This way, receipts always arrive in time, and uploads won't ever choke your broadband connection again!


cFos Traffic-Shaping technology recognizes a number of important packet types and prioritizes them not only to keep Internet traffic running smoothly but also to ensure particularly low ping times. This not only accelerates surfing and download speeds significantly, but it is also a decisive advantage for online gaming.


With cFos Traffic Shaping, you will notice measurable improvements and benefits like:
* Full download rate during upload
* Consistently quick response time while surfing the Web or running other applications
* Improved VoIP speech quality


Without Traffic Shaping, ping times can easily reach a horrific 2 seconds, which will make participating in Telnet or SSH sessions a chore – if not outright impossible. But with cFos Traffic Shaping, latency remains normal.


This alone should make for a totally new surfing experience!


It also means that while surfing the Web, you will be hard-pressed to even notice that there are any data transfers running in the background. Again, such drastically reduced latency will come in especially handy for online gaming.


First, cFos Traffic Shaping measures upstream and downstream rates as well as ping delays for each Internet connection. It then uses this information to control the scheduling of all Internet data transfer. In addition, Traffic Shaping does assign the available bandwidth dynamically to each individual connection as needed.


Not only does cFos Traffic Shaping prioritize ACKs, but also other important packets like those used for Telnet and SSH. Thus, with cFos Traffic Shaping, filesharing programs or mail uploads choking your connection will finally be a thing of the past!


Besides prioritizing ACK packets, Traffic Shaping performs or lets you perform the following:
RX Shaping
ensures ping times remain low even during downloads, while keeping one download from choking other simultaneous downloads.
ACK-Filter
optimizes TCP/IP acknowledgements, thus making more bandwidth available in the upstream channel.
Prioritizing individual programs
like games while assigning lower priority to others is especially useful when trying to reserve some extra bandwidth for important applications.
Voice over IP (VoiP) speech quality
is improved by recognition and prioritization of RTP packets.
Prioritizing other protocols through layer-7 analysis,
like HTTP, FTP, POP3, SMTP, ICMP, SSH, Telnet, and DNS can be done using built-in, programmable filtering rules.


Test it on your own!
I'm sure that you will see the benefit from the first second ;-)

Our mind's best friend!

My beloved everyday-tool goes 7!
I'm talking about the application that gave to my life [personal & professional] the amazing "flavor" of creativity and differantiation. I'm talking about MindManager.
If you are unfamiliar with the Mind Maps term take a look here.
If you have created a MindMap even for one time, I'm sure that you know MindManager.

I had the opportunity to test the latest beta and I have to admit that I'm so excited and I can't wait for the final version! [May 30]



The new version goes mindmapping another step forward:

Ribbon UI
MindManager Pro 7 uses the new Microsoft Ribbon UI to create a streamlined, uncluttered workspace!

Integrate MM7 within Microsoft Applications
Link to topics from external applications. (i.e. Launch maps from Word docs.)

Central Topic
The Parent Topics are hidden and the new central topic becomes the (Central Topic) and the hierarchy starts from what was formerly the Subtopic.

Topic Styles
Allows creation of named topic styles and using these styles across current map regardless of the level at which topics are located.

Split topic
Create new topic based on text sub-selected in topic editor

Highlight Multiple Topics
Shift + Mouse click selects multiple topics for quick multi-formating

Saved Queries
Allows saving queries in Power Filter/Select/Bookmark dialogs and re-using these queries later.

Saved Views
Saves current view (filtered topics, collapsed topics, zoom factors) and allows reusing these views later.

Multiple Markers within Topics
Option to add more than one marker giving you flexible marking

Add Multiple Attachment to Map
Use multi select in file browse dialog to add multiple attachments to a topic

Advanced Sorting
Implemented sort options for icon marker groups and color marker groups. Allow reverse sorting of text marker groups. Available via markers group context menu, but not available for priority and task complete groups.

The improvements are not stopping here, moving the new MM version to a new very promising level.

It's time for all of you to come to MindMaps amazing world ;-)

Thank you SendSpace!

All this time I was looking for a good, reliable, file hosting service to host my large WAV brainwave files.
Most of these files are more that 100MB and it was really a bad experience to try hosting here or there.

The good friends from SendSpace seems that they are like my work here and showing their kindness, gave me for FREE a Pro account of their AMAZING file sending/sharing service!

So Anabubula.com just got its first Sponsor!

The last that I can do is to create a small presentation [srceencast] for this great service...

So please take a look here what are you missing if you don't use SendSpace!

Thank you SendSpace, thank you Joseph!
