BetterOS.org : an attempt to make computer machines run better
BetterOS.org is dedicated to freely providing software to you, which runs better.
Today's computers have gotten very fast. Moore's Law states the the number of transistors that can be built into a microchip will double every two years. Theoretically, this means that (in general) the speed of a computer doubles every two years. This law has been proven to hold true for a long time now. Computer processors get faster and faster as time progresses, and also use less power.
So, a computer from two years ago should be twice as slow as a new computer today, correct? That would be true, if computers were only hardware, but computers also need software to perform any kind of useful task. Wirth's Law states that computer software is becoming slower faster than computer hardware is becoming faster.
The modern software developer has gotten quite lazy. When computer programming was beginning, programmers had to be careful not to use too many resources, and to make sure their programs ran as efficiently as possible. Many programs were written in Assembly in that day. Then computers got faster, and faster and faster, and now today, programmers write code in C#, or Java, which gets compiled to byte-code (not machine code) and interpreted by a virtual machine, and uses garbage collection, because today's programmers are too lazy to even manage memory properly, I can't think of a better way to waste resources. Nowadays, everybody is worried about "going green" and conserving our planet's resources, but in the meantime we are wasting all of our computer machine's man-made resources.
How do programmers get away with writing such bad code, you ask? They don't care, and many of them believe that computers are so fast now that no one will notice. Unfortunately, nobody is noticing, but the only reason is because nobody knows what good software looks like anymore. Computers used to run on 64 megabytes of RAM with 1 gigabyte hard drives, now we have 2 terabyte hard drives and 4 gigabytes of ram, and we still use all of it. We don't do new things, we watch videos, write documents, browse the web, so why do we need all that RAM and hard drive space?
Because application programming has gone to hell.

The Browser Hacker's Handbook gives a practical understanding of hacking the everyday web browser and using it as a beachhead to launch further attacks deep into corporate networks. Written by a team of highly experienced computer security experts, the handbook provides hands-on tutorials exploring a range of current attack methods. The web browser has become the most popular and widely used computer "program" in the world. As the gateway to the Internet, it is part of the storefront to any business that operates online, but it is also one of the most vulnerable entry points of any system. With attacks on the rise, companies are increasingly employing browser-hardening techniques to protect the unique vulnerabilities inherent in all currently used browsers. The Browser Hacker's Handbook thoroughly covers complex security issues and explores relevant topics such as: [+] Bypassing the Same Origin Policy [+] ARP spoofing, Social Engineering, and phishing to control browsers [+] DNS tunne

VHDL Verification Course
Verification is an important part of any ASIC design cycle. It's important that complex designs are simulated fully before prototypes are built, as it's difficult to find bugs in silicon and going through additional layout cycles is costly and time consuming. VHDL is well suited for verification. This course is an introduction to VHDL verification techniques. It assumes some familiarity with VHDL.
