Book Review: Trout on Strategy

From the same author that helped bring us the classic “The 22 Immutable Laws of Marketing”, Jack Trout provides another amazing book, this time focusing on strategy. As he puts it:


“It's all about having the right strategy. That's because strategy sets the competitive direction, strategy dictates product planning, strategy tells you how to communicate internally and externally, strategy tells you on what to focus.”

Book Review: Peopleware


This book is simply a classic and demonstrates that most software development issues are people issues, not technical issues. I should of read this book years ago.


It is the one thing every software manager needs to read . . . not just once, but once a year.”

--Joel Spolsky





It's easier to manage technological issues than it is to manage sociological issues.


Getting a new disk drive installed is positively trivial compared to figuring out why Horace is in a blue funk or why Susan is dissatisfied with the company after on a few months. Human interactions are complicated and never very crisp and clean in their effects, but they matter more than any other aspect of the work.”


Personally, I'd much rather help someone work through a tough algorithm than help them deal with their personal issues. The reality is that over the last seven years of managing developers I have come to realize that personal issues come up as often, if not more often than any technological challenges. This is very much the same topic covered in “First, Break All the Rules.” Care about your people and their personal issues. Help them where you can, but most importantly, just listen. It's just as important as helping them with the technological challenges they face.


Some Great Quotes From The Book:

  • There Ain't No Such Thing as Overtime

  • People under pressure don't work better; they just work faster.

  • A policy of “Quality - If Time Permits” will assure that no quality at all sneaks into the project.

  • The manager's function is not to make people work, but to make it possible for people to work.

  • It's not the quantity of hours that are important, it's the quality. (paraphrased a bit)

  • The final outcome of any effort is more of a function of who does the work than how the work is done.

  • Get the right people, make them so happy they won't want to leave, turn them loose.

  • Sociology matters more than technology or even money. It's suppose to be productive, satisfying fun to work.

  • Process improvement programs don't work because they entice the play-it-safe behavior of low-risk, and therefore low-benefit, projects. (paraphrased a bit)

  • Companies of knowledge-workers have to realize that it is their investment in human capital that matters most.

  • A real working meeting is called when there is a real reason for all the people invited to think through some matter.

  • And my personal favorite: The ultimate management sin is wasting people's time.


Office Space

The second part of the book focuses on office space:

  • Quiet work environments = More Productivity = Higher Quality

  • More square feet per worker = More Productivity = Higher Quality

  • Stealth Development Offices are Great

  • Walls and doors are good things.

  • Appearance is not important, functionality is important.

If you manage software developers, you need to read this book.

MySQL Proxy

I stumbled upon MySQL Proxy today. It's in Alpha stages right now, but it looks like it's going to be great. Thanks to the keepalived project we have been able to load balance and fail over MySQL read queries for a long time now.

But this software has some cool new features:
  • Query Analysis
  • Query Filtering
  • Query Modification
And they've even built in support for the Lua language. I first heard of Lua from Lighty and I'm even more fascinated now that MySQL Proxy has support for it too. Basically, you can add hooks at any of these stages:

  • connect_server
  • read_query
  • read_query_result
to modify, rewrite, track, or do practically anything you want. Awesome stuff. Here are some example scripts.

'watch' Linux Command

Today I learned a new Linux command called 'watch'. watch repeatedly runs a command at a specified interval, showing the output of the command in full screen. The '-d' option is nice because it will highlight differences between each run. Looks like this little command was written in 1991 and updated in 1999.


watch -n 2 uptime

New Linux Command (tcpdump)

From the man page:

Tcpdump prints out the headers of packets on a network interface that match the boolean expression.

Example:

tcpdump -i eth0 -n dst port 389 and not src host 192.168.1.50

Dumps all traffic to port 389 that is not from ip 192.168.150

Awesome.

Book Review: The Pragmatic Programmer


This is one of the best books I've ever read on being a "Professional Programmer." My two favorite parts of the books are the "Goals" section in Chapter 1, and the final paragraph of the book.

Goals
-----
* Learn at least one new language every year.
* Read a technical book each quarter.
* Read nontechnical books, too.
* Take classes (or go to trade shows)
* Participate in local user groups.
* Experiment with different environments.
* Stay current. (Read magazines / journals)
* Get Wired. (RSS Feeds, News Groups)

The final paragraph sums up what the book is all about:

We want to see pride of ownership. "I wrote this, and I stand behind my work." Your signature should come to be recognized as an indicator of quality. People should see your name on a piece of code and expect it to be solid, well written, tested, and documented. A really professional job. Written by a real professional. A Pragmatic Programmer.

Vista Ultimate

My beta for Vista is finally expiring at the end of this month, so I decided to re-install my OS this week. I decided to install Vista Ultimate. Although my fellow geeks were pushing me towards Ubuntu I just couldn't make the switch.

First, an operating system is only as good as the applications that are made to run on it. Windows still dominates in this area. The applications made for Windows are just better, period. Don't argue with me, you know you are wrong.

Anything I've ever needed to do on a Linux machine can almost always be done via SSH. So I have no compelling reason to make the switch. I don't have some burning desire to see Microsoft lose the OS war. I think they will continue to dominate for a long time because of my first point above.

And let's not even get into the whole driver issue. Everything just works on Windows (OK, except for my old wireless card), but at least I don't have to install a new video card and I can print in color.

Thus far, I've installed the following applications:
1. Putty (SSH), have to have, it's awesome, I wish it had tabs though
2. AIM (the real one, not GAIM) The latest version is awesome. I even figured out how to turn off those annoying exploding smileys.
3. Firefox (it's just faster and better than IE)
4. Microsoft Office Trial, MS Office kicks butt compared to Open Office (don't argue with me, you know you are wrong), plus I need to test Outlook 2007.
5. Programmer's Notepad, after all these years Microsoft still has the worst text editor out there.
6. Paint.NET, I use it for cropping images

And finally, I think Windows is every bit as stable as any other OS out there. I've never had problems. I think people that do have problems usually have some other type of issue such as hardware or bad drivers and they don't know how to investigate it properly.

So, for all you Mac and Ubuntu users, give me reasons that your OS is BETTER than (not "as good as") mine, and maybe I'll consider not activating this copy of Vista. I doubt you can do it. ;)

Adding Using awk

Today I had a need to take a file that was formatted like:

40.00
34.00
100.50
...
3902.00
50.00

and add up all the numbers. The file was huge so I didn't feel like opening it with Open Office. I knew there had to be an easy way to do this without leaving my shell in Linux. So after about 5 seconds of Googling I found this little gem:

awk '{x+=$1} END{print x}'

Works like a champ:

How important is email?

I saw this fact on ClarkHoward.com today:

According to Information Week, three-quarters of people say that e-mail is essential to their lives. When asked what that means, 40-50% say they prefer e-mail to chocolate, coffee and TV. And, 60% spend more time sending e-mails than they do on the phone. 15% say they would rather lose their spouse than not have access to e-mail.

I guess I'm in the right business. :) But seriously, give up your spouse? Now that's pretty bad!

For me, checking my email is usually the first thing I do when I wake up, the first thing I do when I get to work, the first thing I do when I get home, the last thing I do before I leave work, the last thing I do before I go to sleep.

If I'm on a trip it's the last thing I do before the plane takes off, the first thing I do when the plane lands, the first thing I do when I get to the hotel, the last thing I do before I check out, and I'm constantly checking my email on my handheld.

And I know I'm not alone, I would even say that my spouse is worse than me. ;)

Book Review: Summer of '49


Pulitzer prize winning author David Halberstam passed away on Monday. I've only read one of David's books but it was fantastic. I'd like to read more because Summer of '49 was an amazing book that any Red Sox / Yankee fan must read.

PHP Performance

We've been working hard the last few days to squeeze every ounce of performance out of our PHP code. This article from Linux Journal was especially helpful:

Life Insurance 101

Making sure my family is taken care of if I kick the bucket unexpectedly is important to me. Keeping my life insurance policy updated is one of the major steps I can take to make sure this happens. But I'm never sure which type of policy (term vs whole), the amount, or the length of a policy I should buy. I trust my life insurance agent, but I like to do a ton of research on my own. So I find consulting my financial advisor very helpful. His advice on life insurance can be found here, very useful stuff, highly recommended.

Book Review: The Ultimate Question


French fries or baked potato?

Khakis or Jeans?

Do I really need to do sit-ups today?

These are all questions I struggle with on a daily basis but none of them are “The Ultimate Question.” The Ultimate Question is a powerful, yet simplistic approach to achieving profitable growth. The book does a great job explaining why customer satisfaction and loyalty is so important and how it will ultimately lead to true growth. Definitely a book the entire organization should read.

Open Files

lsof -p process_id | wc -l

is just way too slow sometimes, I finally figured out a faster (and more accurate) way to quickly get a count (or list) of open files.

ls -l /proc/process_id/fd/ | wc -l

Running Version 2

I finished my 10 week running plan over a month ago. I've been slacking since then, but today I'm going to pick it up again. I'm going to start training for that 5K I have to run at some point this year. My 10 week plan worked out great. It wasn't too hard, I had more mental issues than physical. Here is the plan for the next 6 weeks:

Book Review: Inside Intuit


This book is one of the most fascinating, intriguing, and entertaining books I've ever read. Every entrepreneur should get a copy of this book. Intuit went through all of the stages a startup company might imagine including an epic battle with Microsoft. Software developers will love all of the great stories about the challenges and hard work that it took to make Quicken and the other Intuit products so successful. Service oriented companies will love to hear about how this company truly valued their customer's and their feedback. Management will love to hear how they acquired companies, raised money, and were almost acquired by Microsoft. A truly amazing story about a startup who beat all odds.

Why Code Reviews Are So Important

Yesterday I spent five hours participating in a hard core code review / bug fix session. The code we were reviewing was rather small, but there were a lot of cases to test. Code reviews can be structured in many different ways, but we took the following approach:

1. Review the functional specification to understand the goals of the project
2. Run a few preliminary test cases to make sure the product met the goals
3. Compare every screen to the designs to make sure they were 100% correct (right fonts, colors, wording)
4. Fix bugs on the spot. This was the most time consuming part, but I'm glad we did this right away, avoiding having to hold another session the following day.
5. This project was primarily modifying existing code to add additional functionality. This means that we can use trac in combination with svn to review only the changes made to each file. This makes the code review process very thorough and very fast. Trac does a great job color coding differences and we were able to find a dozen or so typos and bugs simply from looking at the trac diffs. We fixed the bugs right away, committed the code, and repeated the process.
6. After we finished fixing all of the bugs we went through a more thorough testing of the entire application to make sure we didn't break anything and that all of the bugs discovered were indeed fixed.

Overall I was very pleased with the results. The code review not only produced many bug fixes, but it emphasizes the importance of good coding, documenting your code, and being able to work with others.

Book Review: Blue Ocean Strategy


I'm posting this one rapidly in hopes that I can cover up my last post before anyone sees it. :) "Blue Ocean Strategy" is a very thought provoking book that puts structure behind strategic planning. It reminds me a lot of "Purple Cow" type of thinking and is definitely worth a read. My only real complaint is the authors don't make the book all that exciting or entertaining. It did a good job putting me asleep on more than one occasion.

The sub-title of the book is "How to Create Uncontested Market Space and Make Competition Irrelevant." The focus of the majority of the book is strategies for discovering your Blue Ocean. I liked their ideas on how to put a process around strategic thinking.

Damn, too late, AMartin is already on my case for the Martha post.... :)

So, what is a Blue Ocean? Just think about how instead of one-upping your competition with the next big feature, how can you make the competition irrelevant by creating a new market space where there is no competition. For example, "Curves for Women" created a new type of health club aimed at the millions of women who hated working out at home, but also hated spending hours at a high priced, intimidating health club. Typical health clubs want you to spend a lot of time there, spend a lot of money, and use equipment that is complicated. On top of that, there are a ton of bulky guys there starring. Curves created a new environment that had equipment that was easy to use and didn't require a lot of time to workout. Curves made regular health clubs and home workout equipment irrelevant by moving into this uncontested market space.

Damn, second comment on my blog, I can tell I'm in trouble so I'll go ahead and post this one!

Book Review: Martha Stewart's Homekeeping Handbook


The sub-title of this book is "The Essential Guide to Caring for Everything in Your Home". I think the key word in that statement is "Everything". This book is huge and covers every topic you could ever imagine with regards to caring for your home.

I'm sure I will get a hard time from some of my co-workers for even picking up this book, much less reading it from cover to cover, but I am definitely a huge Martha fan after reading this book.

A word of warning though, this book reads like an encyclopedia. Martha has a lot of talents, but don't expect her to crack a joke or two when discussing the proper way to clean your sink.

You can see why Martha has been so successful in her life (going to jail aside), she doesn't do anything unless she does it 100%. Anything worth doing is worth doing right, even if it is cleaning a toilet, you should know the right way to clean it. Another lesson from the book that can be applied to any area of life is being organized. It's amazing how much better you feel after you clean and organize a room in your home. Over Christmas break I spent almost a full day with Velvet organizing our garage. It's gone from being an eye-sore to my favorite room in the house.

Being a home owner (well, the bank technically owns it, but in 26 more years it will be all mine) I want to do everything I can to maintain my home and make it a place where I enjoy returning to after a long days work. I learned a lot from reading this book and I would recommend it to anyone.

Book Review: The 22 Immutable Laws of Marketing


This book is on Joel's reading list and was occupying space on Pat's bookshelf so I decided to steal...errrr...borrow it for the week. Working for a company that is heavily driven by marketing, it's important for me to learn as much as possible on the topic. This is the second book I have recently read on marketing. The first was “The Purple Cow” written by Seth Godin. I found both books very good and hard to put down. This book is a little more outdated in terms of the examples that it provides, but is nonetheless a great book. As I was reading the first few chapters, I had the urge to argue in my head the validity of the laws. But after reading the entire book I understand now understand each law and I would argue that each one is indeed immutable.
