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,
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.
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.
