Review: Redis Applied Design Patterns

Redis is one of the most popular NoSQL databases, and for good reason. Even though you wouldn't want to use it as your primary datastore, Redis is a high-performance complement for caching frequently used data and running certain types of calculations such as leaderboards. I'm far from a master of Redis, but my presentations about Redis are some of my most popular online content, getting thousands of views every month.

In the Packt Publishing book, Redis Applied Design Patterns, author Arun Chinnachamy provides a concise guide to Redis for experienced developers wondering what Redis can do for them. The book opens with a crash-course 3-chapter primer on NoSQL for those coming from a background in relational databases. After that, the rest of the book focuses features unique to REDIS within the context of application use cases such as caching and auto-suggest features.

The initial chapters feel a bit rushed and amateur, featuring statements like this one that are likely to provoke anger or amusement in experienced developers (bold emphasis mine):

The main advantage of NoSQL is that there is no concept of normalization. This is the reason why you get more performance from a NoSQL database when seen against a normalized SQL database. There is a trade-off in that you are sacrificing data consistency in the NoSQL database, but the benefits achieved in doing so are higher.

Despite that, I'm still a fan of having a central point of reference for each major technology that I employ in my stack, which is one of the main reasons why I maintain that my Rails Way series is still valuable after all these years. Otherwise you're reduced to bouncing around a myriad of online sources, an effort that can be frustrating and overly time consuming. This case is no different, the Packt book is a good central point of reference to Redis, although I would advise ignoring the more subjective parts of the book and making use of it purely as a reference tool.

Overall the author employs a concise, direct style that makes it easy to read and digest. It is also chock full of pointers to external resources, making it a good all-around guide to have around when working with Redis on a day-to-day basis. It's only $11 for the ebook version, which makes it easy to recommend.

The Future of Consulting

I am doing an online (live) panel discussion with special guests a little less than an hour from now.

https://www.airpair.com/airconf2014/keynote/future-of-consulting

Here is a brief list of topics that we hope to cover:

- state of software consulting today. static? growing?
- what are the external forces shaping change in the industry?
- opportunities of ongoing engagement outside traditional project-based models
- should firms be looking to unbundle services?
- or additional bundling and/or co-promotion of educational and othe rservices (ala Thoughtbot)
- what is the proper balance of generalists vs. specialists on staff? what are hiring challenges?
- how does a firm stay “top of mind” at clients between projects?
- deployment of proprietary tools make sense? shared IP?
- pricing: time vs. value based?
- new competitors and business models? real threat?
 
Feel free to add questions for the panelists on the talk page's chat section here. To access the chat, you must be registered for AirConf and RSVP for the panel. If you're a little late to the show (starts 3pm ET) don't worry, you can just hit play on the Youtube player and watch it from the beginning. We'll try to address any questions/comments posted before the scheduled end time around 4pm ET.

How to Write and Publish a Technical Book (and make lots of money)

Over the course of the last few years, the tech publishing market has changed. Authors are in a much better position than ever before.

If you are serious about success as a technical author, here are your up-to-date instructions. As long as your content is solid and valuable to your audience, I believe this is how you make the most money. You'll also reap serious long-term benefits.

First of all, are you talking to a publisher about a book deal already? Maybe you have a book proposal and/or outline in hand already?

Good. That's a good starting place, but it's time to get in the driver's seat. Put the discussion with the publisher on hold. Be nice and tell them that you're interested in doing a book with them later in the year. Promise to get back to them once you make progress on your manuscript.

Many publishers will balk at this change of events, but don't worry about it. What I'm going to teach you is how to build leverage. You're going to need as much of it as possible later on when you go back to them.

Now, I'm assuming that you have a title and concept worked out.

At this point you should also have a first draft of a book outline. Go to leanpub.com and create an author account. As part of signing up you'll have to create a book. Enter your title and description. Follow the instructions for creating and uploading a cover image. It doesn't have to be fancy.

Done? Publish your leanpub landing page and announce the book project to your social network. You want to start generating interest from your audience of early adopters as soon as possible. You also want the search engines to pick up your new landing page and start building a foundation for traffic to flow its way.

Time to start writing the book. (I can give you advice on how to be an effective writer, but that's a separate topic. Make sure to subscribe to the mailing list below to find out more.) While you are writing, your leanpub landing page collects email addresses of interested parties. Many of them will freely tell you how much they're willing to pay for the book when it's available. That's very valuable information.

Time to publish.

Publish your incomplete book on leanpub once you have 3 chapters written. Doesn't matter if 3 chapters is only 10% of your book. If you wait longer than that you are losing income and valuable feedback from early adopters. The great news is that at that point, you start earning 90% royalties even though the book is far from complete. I promise that the income and interest from your early buyers will keep you motivated to make progress.

Keep writing.

This middle phase will take between 3 and 6 months for most people, perhaps more for difficult topics. Keep publishing every time you finish a new chapter or have significant amounts of new content. Keep making money throughout this time.

Back to the negotiating table.

When you get to about 75-80% finished then you want to contact traditional publishers like Wiley or Pearson and/or whoever you initially spoke to about a book in the first place. Tell them that you're interested in their best offer. The best thing that can happen at this point is a bidding war over who will publish your title. (You shouldn't bother with Pragmatic Programmers. Want to know why I say that? Subscribe to the mailing list below.)

Cash Advances

If you're a first time author with a popular topic, traditional publishers should be willing to advance you at least $5k USD. That is money that you'll never have to return, which is why publishers seem stingy with advances. It's all risk to them. But since your book is almost done, you've gone a long way towards mitigating that risk for them. That should loosen their pursestrings somewhat.

Half of the advance will be payable on signing the book deal. The other half will be payable on delivery of final manuscript. Consider the promise of that money your incentive to make a final push and finish the book.

Royalties

Royalties for print should start at 18% of net revenues to the publisher. (Expect that figure to be around $10-20, so you're only making a few dollars on each sale. That's just the way it works, don't fret about it.) The real money comes later, when you open up new business opportunites. But that's another topic.

Royalties are not a single number. You'll also negotiate a multi-tiered ramp up to 25% royalties as your sale numbers grow and hit stretch targets. Selling 10 thousand copies of a print tech book these days is a solid success and should be compensated accordingly.

What about ebooks?

You're going to negotiate hard for a 25% royalty on ebooks, but be willing to accept a little less. Don't get greedy and blow it.

Profit!

Once you negotiate a deal you're happy with, sign it and finish your book. Submit the manuscript and get the balance of your advance. Plan on discontinuing Leanpub sales once the officially published version is available on Amazon and in stores.

You'll be cashing royalty checks every six months. Plus you get many other intangible benefits. Traditional publishers can open the door to other writing opportunities in periodicals, speaking engagements and even video appearances. There's also the credentializing effect! Every other schmuck these days has an ebook. But traditional print still provides a strong foundation for launching successful consulting careers.

TechPeaks: Startup Life in the Italian Alps

Last summer (2013) I was honored with an invitation to serve as a mentor for the inaugural group of entrepreneurs welcomed into the TechPeaks accelerator program. It opened my eyes to what's possible when a progressive local government achieves effective cultivation of innovation and startups. Quite an experiment the Italians pulled off last year, and the results have encouraged them to do it again this year, with notable evolutions to their program that I believe make it an even better opportunity for aspiring entrepreneurs.

Techpeaks-main

Here's one of the coolest aspects of it, that really sets this program apart from traditional accelerators such as YC and TechStars: You don't even need to have a startup idea or be part of a team to qualify!

There are two ways to apply to the program: 1) with an idea, team optional or 2) as an individual technologist without an idea. If you get accepted without an idea, the program functions as a matchmaker, with the expectation that you will band together with other people in the program on their ideas, or come up with new ideas to pursue. Out of a total of 50 participant slots available, a maximum of 20 are reserved for these individual explorers.

If I didn't have a family and my own startup at the moment, you better believe I'd be knocking down their door to accept me as an explorer.

Trento-Italy

All participants are relocated to Trento, a college town with some of the most gorgeous vistas I've ever seen, nestled in between vineyards in the Italian alps. It's a relatively quick train trip from Milan and a fantastic place to live. Your accomodations and living expenses are covered by the program, which has a duration of four months, from March 25, 2014 until July 25, 2014. Teams that make progress are eligible for hundreds of thousands of euros in startup grants and additional follow-on funding if they continue operations in the Trento area.

The TechPeaks 2014 application deadline is January 20th. I encourage you to check it out.
