Go inside the computer to uncover the inner workings of the CPU including the Control Unit, the ALU, registers and much more.

The CPU design used in the video is copyrighted by John Scott, author of the book But How Do It Know?.
There are a few small differences between the CPU in the video and the one used in the book. Those differences are listed below but they should not detract from your understanding of either.
CONTROL UNIT - This component is called the Control Section in the book. It is called Control Unit here simply because that is a more common name for it that you might see used elsewhere.
LOAD INSTRUCTION - In this video, what's called a LOAD instruction is actually called a DATA instruction in the book. The Scott CPU uses two different instructions to move data from RAM into the CPU. One loads the very next piece of data (called a DATA instruction in the book) and the other uses another register to tell it which address to pull that data from (called a LOAD instruction in the book). The instruction was renamed in the video for two reasons: 1) It might be confusing to hear that the first type of data we encounter in RAM is itself also called DATA. 2) Since the LOAD instruction from the book is a more complex concept, it was easier to use the DATA instruction in the video to introduce the concept of moving data from RAM to the CPU .
IN and OUT INSTRUCTIONS - In the Scott CPU, there is more involved in moving data between the CPU and external devices than just an IN or an OUT instruction. That process was simplified in the video to make the introduction of the concept easier.
ACCUMULATOR - The register that holds the output of the ALU is called the Accumulator in the book. That is the name typically used for this register, although it was simply called a register in the video.
MEMORY ADDRESS REGISTER - The Memory Address Register is a part of RAM in the book, but it is a part of the CPU in the video. It was placed in the CPU in the video as this is generally where this register resides in real CPUs.
JUMP INSTRUCTIONS - In the book there are two types of unconditional JUMP instructions. One jumps to the address stored at the next address in RAM (this is the one used in the video) and the other jumps to an address that has already been stored in a register. These are called JMP and JMPR instructions in the book respectively.
MISSING COMPONENT - There is an additional component missing from the CPU in the video that is used to add 1 to the number stored in a register. This component is called "bus 1" in the book and it simply overrides the temporary register and sends the number 1 to the ALU as input B instead.
REVERSED COMPONENTS - The Instruction Register and the Instruction Address Register are in opposite positions in the diagrams used in the book. They are reversed in the video because the internal wiring of the control unit will be introduced in a subsequent video and keeping these registers in their original positions made that design process more difficult.
OP CODE WIRING - The wires used by the control unit to tell the ALU what type of operation to perform appear near the bottom of the ALU in the video, but near the top of the ALU in the book. They were reversed for a similar reason as the one listed above. The wiring of the ALU will be introduced in a subsequent video and keeping these wires at the top of the ALU made the design process more difficult.

HakTip: Maltego - Open Source Intelligence and Forensics
maltego is a very important and interesting tool to collect information about persons and companies and websites and phones
مجموعة فيديوهات لشرح اداة قوية وشيقة لجمع المعلومات
من قناة hack5
مشاهدة ممتعة
In this episode of HakTip, Shannon introduces Maltego, a data collection program for penetration testers.
Maltego is a program built into Kali Linux that lets you do reconnaissance on any person, by scraping up data from all publicly available areas of the Internets. Maltego is used for information gathering and data-mining, and can be useful for anyone who needs to gather data on a person or company.
For my series on Maltego, I'm going to be using my Kali Linux VM. To open Maltego, just type maltego into the command line.
Go through the registration process for the free community version of Maltego and sign up! There is also a paid version that can be used for more detailed outputs and for penetration testing in a business setting.
Open a blank graph and you're golden! You'll notice this thing called a palette on the left side. This will show you all sorts of entities we can gather data on. You can drag and drop whatever entity you want to mine data on. Whatever item you end up dragging and dropping onto your graph will end up being a node. For my example, we'll gather data on hak5.org. You can also change this by double clicking inside the domain box on your new graph. But my graph still looks kind of boring so lets gather some specific data. To do so, you'll right click on your domain box, then choose to "run transforms". This means it'll run a search based on your option.
So now that you've gotten a chance to check out the options under run transforms, choose one that you are interested in learning about. First off, I can run a transform on the email domain associated with Hak5.org and I find that there's a few out there available publicly. Next, I can look for the website address, which should be hak5.org. I can right click on the server looking icon and choose the transform labeled ToServerTechnologiesWebsite. Now when it's done, we can see Hak5 is running on Apache, with wordpress, PHP and Google Analytics both added.
Why is this useful? Well, if Hak5 hasn't updated their Wordpress creds in a while, there may be a vulnerability there. Maltego gives you a fast and simple way to search for specific information on a site, in this example Hak5, and return valuable information in seconds.
Let me know what you think. Send me a comment below or email us at Tips@hak5.org. And be sure to check out our sister show, Hak5 for more great stuff just like this. I'll be there, reminding you to trust your technolust.

Hyper Threading Explained
This is an animated video explaining what is hyper threading. Hyper threading is a technology developed by Intel that virtually doubles the cores on the CPU. Making the CPU run faster and more efficient by scheduling the workload between the cores.
