By My Own Hand





Want to create your own font?
It's not that hard. You can do it in about 15 minutes.Go to this site:
https://www.calligraphr.com/en/webapp/app_home/?/

Download the two forms, print them out and fill them in with a felt tip pen.


You will need to Scan them back in and upload them back to Calligraphr.com then download and install the generated TTF font.Name the font  whatever you like, I named mine "Bobs Font".

OK, I have to admit. This may seem geeky. But it gets worse.  Go into any text document, (like Notepad). set the font to your font..  Turn on Speech Recognition. Talk fast and watch your computer screen type, IN YOUR OWN HANDWRITING, everything you say.

             It's CREEPY.....

Think of all they years you wasted taking hand written notes.

The Current War

 Did Edison invent the lightbulb?
There may be a new movie soon about Edison.
Edison was  not who we were taught.

On Ocrober10th 2019 I talk about the Current War.

 I also provide a wallpaper in both single monitor and dual monitor versions;

Thomas Edison and George Westinghouse had a war over AC  or DC.

Dad vs.Grandpa.


When  kids misbehave,  Dads  take away their electronics.
Grandpas take away the chargers and watch the agony while the batteries slowly go dead.

Black Widow

There was a comic book made for AOC that made  her look like super woman. I thought it would be fun to depict her as a black widow spider. Besides, I was bored. So here is a wallpaper for your desktop.

QR Codes

QR codes don't have to be ugly.

This first one streams live radio from WTLS in Tallassee Alabama.
This one should launch your favorite browser and bring you here.








These can be read because the specifications for the percent of fill or emptiness of a cell allows for less than perfect printing. Ditto for the contrast levels.

While the QR code can contain numeric, alpha-numeric or even Binary data, what your phone does with the text will depend on particular phone, operating system or App you use to scan the QR code.

TWO OUT OF EVERY FIVE AGREE...

TWO OUT OF EVERY FIVE AGREE...
Converting a binary number into a Decimal Number is confusing.
Seems simple enough.


16 8  4  2  1   <--- The weights of the bits in a Binary Coded Decimal number (BCD)
 1  0  0  0  1    To find the decimal value just add up the weights of all the "1" bits.

So, to convert 10001 BCD to decimal, we just add 16 + 1 and get 17 decimal

To be more exact, we just converted a Binary Coded Decimal  (BCD) number to decimal.
However, BCD isn't the only way of coding a binary number.

Consider 2 of 5 binary numbers. The weight of each column is different from regular BCD.

 6  3  2  1  0     The weights of the bits in a 2 of 5 coded binary number (2 of 5)
 1  0  0  0  1      Again, we just add up the weights of the "1" bits.
                         So 6 + 0 = 6
In 2 of 5, we always have 5 bits and two of them are "1"s while the others are "0"s

Here is the complete list:


6 3 2 1 0 <--- The weights of the bits in a Binary Coded Decimal number (BCD)
0 0 0 1 1     1 + 0 = 1
0 0 1 0 1     2 + 0 = 2
0 1 0 0 1     3 + 0 = 3
0 1 0 1 0     3 + 1 = 4
0 1 1 0 0     3 + 2 = 5
1 0 0 0 1     6 + 0 = 6
1 0 0 1 0     6 + 1 = 7
1 0 1 0 0     6 + 2 = 8
1 1 0 0 0     6 + 3 = 9
0 0 1 1 0    2 + 1 =  0  (there are two ways to form "3", so this combination is taken to be zero.)

Notice that there is no way to combine two "1"s and three zeros to represent a decimal zero. Yet, there are two ways to convert a decimal 3 to two of five binary,

6 3 2 1 0  <--- The weights
0 1 0 0 1     3 + 0 = 3
0 0 1 1 0     2 + 1 =  3

Movie Shorts on DUST - Frankie

My movie pick this week is Frankie(click to watch)
Frankie is an inventor and watchmaker with severe OCD (Obsessive-Compulsive Disorder)
When he receives an old pocket watch, he discovers it is a time machine. 

The only problem is that he is not the only one who wants this watch. Frankie is also paranoid.
He becomes obsessed with a stranger who Frankie believes is going to steal the time machine.

An almost silent film with few words. If the ending leaves you a little confused, it's supposed to. It's about the Grandfather Paradox. Your not supposed to be able to go back in time and kill your grandparents because you would never have been born.
Frankie is a "pure-bred" sci-fi adventure with retro elements. I love the timer Frankie made that is a modified part of an old hair curler. 
Here is a wallpaper I made for Frankie. Download it and set it as your desktop background.

Bobs home made drive.

As a geek, I like speed. But, I'm a cheep geek. Spending a grand for a hard drive is fatuous. Especially when I can build one that is four times faster, for one fourth the price. 

While You can buy enterprise grade PCIe disk drives, they are pricey. An Intel 1 TB PCIE SSD drive  is over a thousand bucks.

My home built internal drive uses the same intel SSD chips mounted on four M.2 drives. The ASUS Hyper M.2 x16 card holds 4 M.2 256GB SSDs. But, instead  of just four data lanes, it puts the drives on 16 PCIe data lanes.

Some cautions here. In order to work your motherboard and processor chip must supply 16 lanes of data to the PCIe slot where you plug in the Hyper card. Most won't. You must use a Intel processor that has 44 lanes, not 16 or 28. The CPU chip must also support VROC, (Virtual Raid on CPU). VROC is a hardware RAID controller built into some i7 and i9 Intel CPUs. I used a i9-9720 chip and an ASUS Prime Delux II motherboard. The drives I used are the Intel 9720p 256GB and the ASUS Hyper M.2 X16 Card.

The Bios on the Asus motherboard will load a VROC extension and allow you to create a RAID-0 of the four individual Intel M.2 drives. When you install Windows 10 you can load a driver from Intel for the combined drives during the Windows 10 installation. The four M.2 drives will then show up as a single drive when you boot Windows. The drive will be drive C: so EVERYTHING will be fast.

The difference between using Four lanes of data and using 16 lanes of data will blow your socks off.
