Happy Birthday to Apple (Macintosh)

On Jan. 24 Apple Macintosh will turns 30 years old.

Over the years, the popular computer has been molded into many shapes and sizes, constantly in redesign mode. Championed by the revolutionary Steve Jobs, Mac computers have risen to the top of the food chain, one of Apple’s many landmark achievements. These days, most Mac computers are sleek and slender, sporting a crisp display and a variety of different size options.

Let`s see the remarkable evolution of the personal computer.

1. Lisa – In 1983, Apple debuted its first model, the Apple Lisa. The computer took more than three years to make, and around $50 million to develop. Named after Steve Jobs’ daughter, the computer was quite pricey, clicking in at nearly $10,000 (about $25,000 by today’s standards). The high price tag repelled most consumers, and the computer sold poorly.
Though not technically a Mac, the Lisa nonetheless influenced the first Macintosh, which Jobs debuted on Jan. 24, 1984.
2. Macintosh XL – In order to ramp up Lisa sales, Apple redesigned the model in 1985, renamed it the Macintosh XL and lowered the price to $3,495.

3. Macintosh 128K - Introduced in 1984, the 128 model was the first true Macintosh personal computer, and retailed for about $2,495. With its 9-inch screen, 128K of RAM and “easy to use” accessibility, the Mac was off to a robust start.

4. Macintosh 512K - Released right after the 128, the 512 was virtually the same, but had four times more memory.

5. Macintosh Plus - Enter 1986, when the Macintosh Plus emerges into the market. It had 1MB of RAM and cost about $2,599. It also came with an SCSI port, which meant users could install external hard drives.

6. Macintosh Portable - The first battery-powered Mac creation entered the arena in 1989. It was considered fast for its time, operating at 16 MHz. Though it was quick, the Portable sold poorly and weighed nearly 16 pounds.

7. Powerbook – The Powerbook came out a few years later, in 1991, and was Apple’s first true portable computer, thanks to its lightness. The floppy disk drive was a separate, external entity. The line had staying power, continuing until 2006.

8. iMac – The iMac debuted in 1998 and was one of Apple’s first big projects after anointing Steve Jobs its CEO. Translucent and brightly colored, the iMac was a stylish step above its predecessors, and did away with floppy disk drives, opting instead for USB ports.

9. iMac G4 - The iMac G4 marveled tech lovers with its flexibility and flattened shape. Because of its thin neck, the screen could be pulled forward and swiveled around. The 2002 creation literally had audiences gasping during Steve Jobs’ keynote.

10. MacBook - Apple trotted out the new MacBook in 2006, noted for its built in “iSight” webcam, crisp and glossy LCD screen and integrated keyboard.

11. MacBook Air - The holy grail of modern day MacBooks, the Air is Apple’s sleekest invention, touted as the world’s thinnest notebook (due in part to the removal of the CD/DVD drive). Jobs unveiled it in 2008, and the line has continued to pump out redesigned and updated models. The original had an 80GB hard drive and bright LED backlighting.

12. iMac today - Thinner and larger than past models, the modern iMac features a slender screen and a detached keyboard and mouse. The most recent 27-inch version sports a lighting-fast Intel processor and Fusion Drive data storage, which combines a traditional hard drive with Flash storage.

#3 OwnCloud - Dropbox alternative for cloud storage service

I was looking for an alternative to Dropbox to run cloud on my own server at home and office. This software is open source software, and it is self hosted. I don't have to trust third party with my data. I found this software easy to install and quite useful. I started to use it for syncing files and other data. I have been using for couple of months and it has been proven reliable alternative to Dropbox. There are clients available for MS-Windows, OS X, Linux, and mobile apps for iOS and Android devices (or simply access data using the ownCloud web frontend).

#4 Docker - FreeBSD like container+API for Linux

The FreeBSD jail provides an operating system-level virtualization partition a FreeBSD-based serve into several independent mini-systems. You can do the same with Linux using OpenVZ. Linux Containers (LXC) is a virtualization method for running multiple isolated Linux systems. Docker extends LXC. It uses LXC, cgroups, Linux kernel and other parts to automate the deployment of applications inside software containers. It comes with API to runs processes in isolation. With docker I can pack WordPress (or any other app written in Python/Ruby/Php & friends) and its dependencies in a lightweight, portable, self-sufficient container. I can deploy and test such container on any Linux based server.

#5 Adminer - A lightweight and full-featured database management tool

Adminer is a full-featured database management tool written in PHP. Conversely to phpMyAdmin, it consists of a single file ready to deploy to the target server. Adminer is available for MySQL, PostgreSQL, SQLite, MS SQL and Oracle. I usually install this for clients who are new to PostgreSQL/MySQL. The software acts as a drop-in-replacement for phpMyAdmin with a better user interface, better support for MySQL features, higher performance and more security.

#6 MariaDB - Drop-in replacement for Oracle MySQL server

MariaDB is a community-developed fork of the MySQL server. MariaDB is going to be default in many popular Linux distro and open source project. Red Hat will switch the default database in its enterprise distribution, RHEL (including its clones such as CentOS), from MySQL to MariaDB, when version 7 is released in 2014. I started testing MariaDB and found no problems at all. The speed is same or better in some cases.

#7 RackTables - Manage your data center assets like a pro

It is also an open-source and cross-platform network scanner designed to be fast and simple to use. It scans IP addresses and ports as well as has many other features.

#10 Jekyll - Create simple static blog

Drupal, Typo3, WordPress and many other content management system (CMS)/blogging software dynamically create feature rich content. However, you may not need all the all features and complexity offered by modern CMS based systems. For example, a WordPress based blog like nixCraft requires multiple VMs, CDN for static assets, caching engine such as memcached, PHP, mysql database, comment moderation, and on going updates. A growing trend is to keep your blog simple by avoiding CMS and use static HTML generators that offers the following benefits:

• No more complex setups i.e. no databases/php/caching engines required.
• No more comment moderation.
• Pesky updates.
• Static files are more secure.
