The already excellent performance has been improved further (including XML performance), and the free edition now takes advantage of up to 4 GB of RAM (but you can have as much RAM on the server as you wish). As usual, there are no limits on database size, number of users, etc — unlike other free versions of commercial databases that are offered by Microsoft and Oracle.

By buying a completely optional subscription for $2,150 a year, DB2 Express-C FTL (Fixed Term License) will use up to 8 GB of memory, 4 cores (as opposed to the 2 cores used by the free edition), adds 24/7 support, and a bunch of high-end features such as HADR (High-Availability and Disaster Recovery), row, column, and label access control, etcetera.

Among the numerous new features present within the free edition, you’ll find:

• Support for historical reporting through Time Travel Query. In a nutshell, this cool new feature allows you to query the database at the state it was in at a given time or within a given period in the past.
• Compatibility with Oracle is now up to 98%, which means that you can easily switch most applications without running into any headaches.
• Support for SPARQL and RDF has also been baked in, allowing DB2 to act as a NoSQL storage solution.
• Control Center has been discontinued in favor of the much more powerful IBM Data Studio.

You can read a detailed list of what’s new in Leon Katsnelson’s article on developerWorks.

Before you ask, no DB2 Express-C 10.1 is not currently available for Mac OS X. (That’s why you see an * in the table above.) However, Mac users who reported issues with Lion, will be happy to know that a recent version aimed at addressing such issues has been released as well. It’s still DB2 Express-C 9.5.2, but it’s an out-of-beta release that should make things much smoother.

If you’d like to learn more about DB2, I invite you to check out the courses available for free on Big Data University.

Download DB2 Express-C for your OS now and give it a shot. Alternatively or in addition, you can also try DB2 Express-C in the cloud through RightScale.

When I first learned about it, I cried. That was an odd reaction on my part. I never met or interacted with Steve Jobs and I’m not what most would define as an Apple fanboy.

I reflected upon what led me to shed tears for someone who was, technically, a stranger to me and came to realize that Steve Jobs affected and inspired my life far more that I cared to admit.

My deep sadness wasn’t just for a relatively young person who died and left a grieving family behind. It was sadness for the loss of a visionary leader who relentlessly showed us the art of what’s possible. I couldn’t help but feel the sudden end of an era. No “one more thing” left to anticipate with excitement and curiosity.

Steve didn’t personally create or invent many of Apple’s products, but he ensured that the end results we managed to get our hands on were nothing short of inspiring. He was a visionary for countless consumers, developers, entrepreneurs, and even competitors.

He managed to inspire a whole industry, while doing what he truly loved. Millions of entrepreneurs world wide have been inspired to do the same as a result of his work. This may be his greatest legacy and something that will live on in all of us long after his passing.

Goodbye, Steve, and thank you for everything.

Early feedback has been great and helped shape the book. The reception by early readers and reviewers has been nothing short of incredible. Here is one:

My career got a huge boost when I got serious about blogging, two years ago. So I’m in absolute awe at this amazing book, going above and beyond the best advice I’ve ever heard on the subject. I wish I would have read this two years ago, as I had to learn this the hard way. Honestly, this book has got me inspired to get back to writing more.
—Derek Sivers, founder, CD Baby, sivers.org

I’m pretty confident, humbly, that you’ll love it. It provides you with all the info you really need to succeed with your own blog, and it does so in an organized manner that will get you to plan, build, promote, benefit from, and grow your own blog.

While useful to a general audience, the book was specifically written for developers and technically minded entrepreneurs (e.g., hackers and founders). Above all, it aims to be a practical book packed with actionable advice, and not your typical fluffy book about blogging.

You can buy the beta here, and please let me know what you think about it once you get around to read it. I’m very excited to be able to share the fruits of much hard work that took most of my evenings and weekends for the past few months.

What’s more interesting to me is that IBM has implemented a completely new full text search engine known as DB2 Text Search, which will probably be available to the public as an add-on in a week or so. We had a couple of different text search engines in the past, but IBM decided to focus on just one and make it as good as it gets. I look forward to playing with it, and reporting here on the blog about its capabilities in a future article.

For the time being, I encourage you to download DB2 Express-C 9.7.4. As a reminder, it’s free, and you can use in production without having to pay a fee.

IBM has been working hard to create a new, substantial upgrade of DB2. Thanks to the Early Experience program, you can now test drive the recently released Alpha 4 in the cloud for free. Despite its name, it’s a pretty solid release, so I wholeheartedly invite you to try it out.

To apply for the early experience program, all you have to do is fill out this form. If you’d like to run DB2 on your own machine, you can get the current edition of DB2 Express-C here (it’s also free).

Over the past 25 years they’ve managed to deeply influence the world of computing and technology. The ideas promoted by the FSF’s foundation and leader, Richard Stallman, have certainly veered on the radical side. However, even if you don’t agree with this group’s ideology, I’d argue that we are afforded a lot more software freedom thanks to their activism.

Free and Open Source software (FOSS) has made our world a better place, and even if we put certain ideologies aside, software that is expandable, adaptable and often (but not necessarily) available for free is certainly a good thing for the end user.

Yet the business world has only partially embraced FOSS, and it’s rare to see an organization that exclusively runs its operations using only Open Source software and web applications that have been released under OSI approved licenses.

There are many reasons why this is the case, but the fundamental one is that software is only a means to an end for most businesses. They’ll use whatever they feel works best, is cheapest, best supported, and that they’re most familiar with. After all, they’re in business to make money, so religiously adhering to software philosophies is not usually at the top of their priority list.

Open Source business models

You’ll notice that for the most part, companies who develop FOSS don’t make their money from that FOSS itself. While they could theoretically sell it, the existence of clauses that allow their customers to redistribute the software for free makes it a less than ideal business model.

As such, better business models had to be invented to workaround the practical (not theoretical) limitations of making money with FOSS. The three most common of which are: dual licenses, Open Core, and support-based (and combinations thereof).

(Note that I’m mostly talking about desktop software here. Open source web apps tend to capitalize on the hosted nature of the service and are easier to monetize even when the software itself becomes freely available.)

Dual license: A commercial license is often used in conjunction with viral Open Source licenses like the GPL. A company setting up a dual license of this kind essentially relies on other companies’ inability to accept the viral license (because they don’t want to give their code away just because they used it in conjunction with your GPL code).

Open Core: The core product is Open Source, but if you want extra features, that are often indispensable to businesses, you’ll have to pay for them (as they’re commercial and proprietary). A company adopting this model is essentially using a freemium model, in which they use Open Source as a gateway to selling you proprietary software (which is the real way they make their money).

Support-based: Finally, there is the support option. Development companies went from basically having a license to print money to a much less scalable business model where they generate revenue based on the support they provide. Incidentally, while support is not the main “vocation” of most people who start software companies, it can be a lucrative avenue nevertheless.

Open Source as a nice to have

My point is that in all three cases, businesses may appreciate the Open Source nature, but it’s not a key factor in their decision making. In fact, in the first case they are buying a commercial license to escape the contractual limitations of an Open Source license; in the second case, they are paying outright for proprietary software; and in the third case, they are paying for the assurance that the software is maintained and that there’s going to be someone who’s accountable and ready to assist if problems arise (this is a real problem with many less popular community-driven Open Source projects).

In short, as long as the software fits the bill, companies will not take an idealistic view when it comes to software, but rather focus on what affects their bottom-line. It’s fairly safe to say that most companies really care about having software that is reliable, saves them time (their most precious resource), and that’s well supported. Open Source is a “nice to have” for most of them.

Why would you use commercial databases?

As an advocate for the DB2 team I often hear people ask, “Why would you use DB2 when MySQL is free and Open Source?”. The truth is that countless companies use DB2 because they know it ends up being cheaper in terms of both time and cost, when compared to Open Source database solutions.

I don’t doubt that many developers who work with Open Source technologies may care about their database being free (as in beer), free (as in speech), and its ability to meet a subset of functionalities available in pretty much any relational databases. In that case, MySQL is fine. But the needs of companies, both large and small, will often differ from that of your typical solo hacker.

IBM has an extensive number of DB2 customers because these companies care about features that don’t exist or are very rough around the edges in many Open Source databases.

Most of our customers care about:

• Proven reliability and advanced security features;
• Utmost performance;
• Ability to natively handle XML documents and data (some industries have to do so as a result of regulations);
• Vertical and horizontal scalability as their business grow;
• Advanced and easySQL Replication and High Availability and Disaster Recovery (HADR) tools;
• Backup compression to save storage costs (it’s not an issue if you have a web app that stores a grand total of 50MB of data, but it’s fundamental when you have 50TB);
• 24/7 support from a reputable company that will truly stand behind the product they sell;
• Ease of administration (DB2 offers autonomic features that pretty much self-adjust DB2 automatically based on the workload and usage it’s handed);
• Overall TCO (which involves a lot more than just looking at the price tag for the software).

DB2 rocks all of these very crucial points. Furthermore, with the DB2 Express-C version, you get to use a production ready version absolutely for free.

Don’t let the name scare you. Oracle has really given the “Express” brand a bad vibe. Oracle XE is full of security holes, hasn’t been updated in 5 years, and is a severely crippled edition. Conversely, DB2 Express-C is regularly updated and impose very little limitations on you.

True, even DB2 Express-C has some limitations when it comes to the kinds of resources that it can use (up to 2GB of RAM and 2 CPU cores). Fear not though, it’s still plenty useful for many startups or small businesses (it’s used in production by many such folks). With DB2 Express-C there are no limits on the number of databases, their sizes, the number of users, connections, etc. It’s the perfect starter edition. The presence of three commercial editions (Express-C FTL or Express, Workgroup, and Advanced Enterprise) guarantees you that as your business flourishes, DB2 will grow with you.

How far can you go with top of the line hardware and the commercial editions? Let’s put it this way: every time you buy something with your VISA, that transaction passes through DB2. Furthermore, DB2 holds the world record for TPC-C benchmarks, with over 10,000,000 transactions per minute.

Let’s make DB2 available to more startups

Today IBM is announcing new pricing to extend the benefits of our support and commercial edition to a greater number of startups and small businesses. You can get the commercial Fixed Term License for about $1,500 per server, per year. (I pay more per year to host this blog.) Aside from 24/7 support, regular fix pack updates, and the clustering option for SQL Replication and HADR, this DB2 Express-C license will also allow you to use up to 4GB of RAM and 4 CPU cores. (There is an Express edition if you’d prefer to pay a one time fee, rather than a yearly one, or if you’d like to pay through other metrics such as per user.)

Commercial databases, particularly innovative ones like DB2, have their place in our industry both today and in the future, even in the face of the indisputable popularity of Open Source options. Businesses should evaluate proprietary and Open Source solutions on technical merits rather than ideological ones. In my opinion, there is space for both of these models to peacefully coexist to better serve the diverse needs of the business world.

DISCLAIMER: These are my controversial opinions on the topic at hand. They do not represent the opinions of IBM or anyone else associated with IBM. In fact, I wrote this post at 2 AM on my own laptop and published it on my personal blog. No executives were consulted (or harmed) in the making of this post.

Apple just released a brand new, gorgeous looking Mac mini. This major upgrade brings us two different models: a desktop one and a server version (priced at $699 and $999, respectively).

Equipped with a HDMI port, the desktop edition of the Mac mini makes for a perfect Home Theater PC. It’s small and stylish, and as such is a great fit in your living room. Most of the reviews I’ve read focus on its use as a highly capable HTPC (despite its lack of a Blu-Ray drive).

However, I see the new Mac Mini in a different light. At $700 it is far too expensive for a HTPC, yet it’s ideal as an entry-level machine for web, Mac, and iOS development (it’s almost as cheap as a Hackintosh, minus the headache).

Mac Minis will do the job and be more than capable thanks to their adequate, albeit not spectacular, hardware specs. If my MacBook Pro were to die today, I would definitely consider purchasing one for development purposes. Would you?
