Fixing Logitech trackball performance

Posted on by

I love these Logitech Marble Mouse trackballs, I have one for every computer.  After a few years they slow down physically.  Cleaning the dust off does not help enough, something different needed to be applied.  I’ve been researching lubricants and oils, doing some tests with households; but I think I’ve found the perfect fluid.  Ian Gomes of Union Sound Company made a recommendation a few years back for Penny and Giles faders.  A quick amazon search lead me to Lucas Silicone Shock fluid.  I must report that it is the perfect product for this application.  If you need a drop, I’ll send you a q-tip of it in the mail.

Generating Code with spreadsheet for Keyboard Assignments of CADSOFT Eagle

Posted on by

I needed a way of Generating Code, lots of code.   In cadsoft eagle, the Keyboard Assignments are completely user customizable.  They have a script language that allows you to modify the software.  I’ve used hundreds of the ULP and SCRs and decided to write my own Generator.

Necessity is the mother of all innovation.  Screen Shot 2015-09-14 at 12.56.34 AM Screen Shot 2015-09-14 at 12.56.45 AM Screen Shot 2015-09-14 at 12.56.52 AM Screen Shot 2015-09-14 at 12.56.59 AM Screen Shot 2015-09-14 at 12.57.04 AM Screen Shot 2015-09-14 at 12.58.37 AM Screen Shot 2015-09-14 at 12.58.44 AM Screen Shot 2015-09-14 at 12.58.50 AM

 

On Compressing the English Language

Posted on by

Someone picked my brain the other day looking for a technique to compress language files.

After walking away to think about it… my method was to re-order the ASCII code to the letters by their frequency and the most common words by their frequency.

Where lowercase e is stored as an ASCII value using 1 byte
ASCII  e = 0x61 = 0b1100001 = 7 bits
vs
APK e = 0x1 = 1 bit

… this method stores an E in 1 bit.  This is similar to the Huffman Code with the addition of whole words being included in the code.

For example:

“because” is the 94th most used word in the english language and in this method is stored in 7 bits.

I don’t know if this has been done before… but I would imagine it could compress Language files substantially.

I have thought about a third addition of using the most used 2 or three letter combinations commonly used.

APK ORDER APK LET FREQ WORD FEQ APK BIN APK HEX APK BITS USED
0 space 0 0 1
1 e 12.70% 1 1 1
2 t 9.06% 10 2 2

IMAX- The Next generation of IMAX sound – 12 Channel configuration – and LASER projectors, about time

Imax – The Next generation of IMAX sound –  12 Channel configuration – and LASER projectors, about time!!

Had a fantastic experience with the new IMAX sound system at the AES meeting held at Technicolor.

The “Upper Quad” ceiling speakers really bring it together.IMG_8687

VBAP is going to need some work… and a HUI

I walked away asking: “If it were truly immersive, there would never be idle speakers”  Cory said: “Backgrounds are the first thing to go…” I think those will become crucial.

I also walked away wanting a dozen U87s…

Of course you could hear the birds chirping and running away WHILE the rocket was launching…
