Book Review: Computers Ltd: What They Really Can’t Do

Hey everybody,
I would like to share a book review that I wrote on amazon.com.
Book: “Computers Ltd.: What They Really Can’t Do (Popular Science)” (2003)
Author: David Harel

Computers Ltd.: What They Really Can't Do

“This book sets the record straight. Computers can’t fix all of the world problems because they’re limited by time and space.

The author starts off by defining algorithms and how computer programs work. He’s then explores common problems in computer science using a fair amount of algebra and graphs, like NP complete problems, the travelling salesman problem, the Turing test, tower of Hanoi, and etc.

Restraining from being a complete pessimist, discussions mainly addressing Cryptography are included. Cryptography shows how computational complexity can be used for the greater good, as it’s nearly impossible to break the encryption within a reasonable amount of time for any data encoded in RSA.

Lastly, the author ends the book with his take on hot areas in computing, such as Quantum Computers, Artificial Intelligence and evolutionary (generic) programming.
Overall, I enjoyed this pocket size book and recommend it for those interested in expanding their knowledge in Computer Science.”

“Beginning MySql” – Book Review

Here’s a book review I did on amazon.com.
Check out more of my reviews at my amazon.com profile page.

Overall, I love this book, because the authors build your knowledge of databases from the ground up.

Before I got my hands on this book, I knew only a limited amount about databases. Now, I understand advance concepts (like foreign keys, transactions and optimization) and can design, implement and maintain my own simple relational database management system.

This is a thick book that took me about 2 weeks to finish and it would have taken even longer if I decided to follow through with all the “Try it out” sections, exercises and useful examples.

“Beginning MySql” covers the majority of MySql 4.1 by using the definitions of syntax and options as their main teaching tool throughout most of the chapters. This makes MySql easy to learn since you can reference the definitions as a cheat sheet when you’re implementing a database design.

One thing that I noticed is that they need more proofreading. Every now and then, you’ll encounter a typo or wrong information but this is expected since the authors warned of this in the introduction.
Example, page 299: “However, bitwise operations support calculations up to 64 buts”.

The best part of the book, is appendix C. It briefly covers MySql 5 but they introduce you to Triggers, Views and Procedures while updating you on MySql new standards. For exmaple, MySql 5 supports foreign keys for all the table engines, not just for INNODB.
If you’re the type that has a hard time reading documentation online, then I would strongly recommend this book. Otherwise you might be able to learn MySql using Youtube and the MySql homepage.

Note: Since this book only converts version 4.1 of MySql, you need to checkout the on-line documentation for changes in MySQL 5.

You can buy the book for less than $10. Link below.

Find data faster.

Stop wasting time and automate repetitive task. Automation increases your productivity and lessens your work load. Here are some few methods to do so.

Launching Programs :

The first improvement you can make is to use the keyboard over the mouse. Operating a mouse requires more concentration and time than hitting a keyboard shortcut and typing in the name of the program.
The easiest way is to use “Launchy”, a open source keystroke launcher. With Launchy, to open up a program like Firefox, you hit “alt” + “space” to bring up Launchy, then you type in “fox” and it auto completes for your and enter.
- Jump Directory ( Make a folder within side start menu for quick access to essential tools)
- Shortcuts

Finding Files

- Everything, (super fast searching).
- Spacemonger or WinDirStat (data storage visualization)
- Q-dir or xplorer2 (dual file manager)

Automation

Autoit (Windows OS Task automation)
Chickenfoot (firefox plugin for web automation)

More time saving tips

Regular Expression Tools: (Searching Through Text)
Poweroff ( schedule your computer to power off after events )

In conclusion, there are dozens of programs and other techniques that you can learn to save time. To take this a step forward, I suggest reading The Productive Programmer by Neal Ford.

Book Review: Don’t Make Me Think

After months of delay, I finally sat down and read “Don’t Make Me Think” by Steve Krug.

Link: Don’t Make Me Think

Finished this short but informative book in 2 days. Steve Krugs gives advice on avoiding common usabilities issues.
With that, here are a few things I picked up.
- Test rather than argue with your team.
- Users read in a hurry, so kill the noise by having less design and small talk, while filling the page up with unique content.
- Avoiding ads on your home page, even though it has the highest traffic.
- Provide aid for lost users. That includes a way to get to the home page, a site id, and other means of understanding their location.
- Test each stage of your project at least once. The earlier the testing, the cheaper to repair.
