Takeaways from Elisabeth Hendrickson’s “There’s Always A Duck”

Elisabeth Hendrickson’s book “There’s Always A Duck” has been around for a number of years but I have only been able to read it recently. Now I know what she meant about ducks. They’re literally about ducks, but also about people too. People are different, and yet we share similarities. We experience things, we communicate with each other, and we learn and get better because of those experiences. Her book tells us stories of her adventures and the lessons she’s discovered along the way, and it was nice to have had a glimpse of what she saw and felt with her encounters with software project teams and everyone involved.

Some takeaways:

  • The vast majority of programmers I have met are diligent, capable folk. They truly care about the quality of their work and want the software they produce to be useful. They work hard to make sure they are implementing the right features and writing solid code.
  • The next time you’re tempted to think of your programmers as idiots, incompetents, or quality hostile, remember that no matter what else they may be, they’re people first. Even if it seems like they’re hostile or incapable, it is far more likely that they are having a very human reaction to a particularly bad situation.
  • And before you blame someone else for a mistake, remember the last time you made one. I’ve made some real whopper mistakes in my time. We all have, whether or not we choose to admit them or even remember them. It may be that some programmers don’t care about users, but it’s more likely that bugs are honest mistakes made under difficult circumstances.
  • Even when we are speaking the same language and about the same thing, it’s hard enough to communicate.
  • The point wasn’t to catch every possible error. What seems to go wrong most often? What errors are difficult to see at first glance, and thus require concentration to prevent? What causes the most damage when it happens?
  • Janet doesn’t know anything about the ins and outs of creating software. She probably doesn’t want to know. She just wants to serve her customers well. And this software is not helping. Back at corporate, the Steering Committee, Requirements Analysts, Designers, Programmers and Testers are congratulating themselves on a solid release. What they don’t see is Janet’s pain. The feedback loop is broken. The team back at corporate has no mechanism to find out whether the software is any good. Oh, sure, they’ll detect catastrophic problems that cause servers to go down. But they won’t see the little things that cause long queues at the front desk of the hotel.
  • Testers naturally notice details. Not only do we notice, but we think about what we noticed, we attempt to interpret our observations to explain why things might be that way, we ask others if they noticed, we question our assumptions, and we poke and prod at things to see if our understanding is correct. We use our observations to inform us, and in doing so discover underlying causes and effects we otherwise might miss.
  • I sometimes fall into the trap of thinking that the first problem I see must be THE problem that needs to be solved. Perhaps the problem I spotted is indeed worth correcting, but I almost never manage to spot the true critical issue at first glance.
  • Both fear and excitement stem not from observable reality but rather from speculation. We are speculating that the bugs that we know about and have chosen not to fix are actually as unimportant to our users as they are to us. We are speculating that the fact we have not found any serious defects is because they don’t exist and not because we simply stopped looking. We are speculating that we knew what the users actually wanted in the first place. We are speculating that the tests we decided not to run wouldn’t have found anything interesting. We are speculating that the tests we did run told us something useful. None of it is real until it is in the hands of actual users. The experience those users report is reality. Everything else is speculation.
  • It’s not because Agile is about going faster. It’s because structuring our work so that we can ship a smaller set of capabilities sooner means that we can collapse that probability wave more often. We can avoid living in the land of speculation, fooling ourselves into thinking that the release is alive (or dead) based on belief rather than fact. In short, frequent delivery means we live in reality, not probability.
  • Hire the right people. If that means keeping a critical position on the team open longer than anticipated, so be it. It’s better to have an under- staffed team of highly motivated, talented, skilled people than a fully staffed but ineffective team. Remember that hiring mistakes often take only a few minutes to make, and months of wasted time to undo.
  • Listen. There are always signs when a project is in trouble: missed milestones, recurrent attitude problems, general confusion about the project. Sometimes these signs indicate a dysfunctional team, sometimes they’re just normal bumps along the road, and sometimes they are early warning signs of major problems. The only way to tell the difference is to listen carefully to what the team members have to say.
  • The best way to get people to accept change is to make it more fun, and more rewarding, to do things the new way.
  • Choose a path that takes you in the direction you want to go. Don’t choose a path simply because it takes you away from the swamp you want to avoid.

Favorite Talks from Selenium Conference Austin 2017

It’s amazing that the recently concluded Selenium Conference over at Austin Texas continues to live up to expectations, building up on the previous conferences and keeps delivering quality talks on automation and testing. And what’s more interesting is to know how they’ve been keeping up with everything with help from the Software Freedom Conservancy and the testing community. There’s even a European Selenium Conference happening on October 9-10, which I’m very much looking forward to.

Meanwhile, here are some of my favorite talks from the Austin conference:

  • Automate Windows and Mac Apps with the WebDriver Protocol (by Dan Cuellar, Yosef Durr, and Stuart Russell, about easily automating Windows and Mac apps using Appium)
  • Automating Restaurant POS with Selenium – A Case Study (by Jeffrey Payne, about automating a point-of-sale system for testing, including credit card readers, printers, cash drawers, and caller IDs)
  • Selenium State of the Union (by Simon Stewart, on an overview of the W3C spec process and about naming things in the Selenium project, how APIs should be correct and how people won’t write their own, how not everyone is a sophisticated developer, and how testing is under resourced)
  • Leverage your Load Tests with JMeter and Selenium Grid (by Christina Thalayasingam, on adding load tests for your system using JMeter and Selenium Grid in combination)
  • Selenium and the Software Freedom Conservancy (by Karen Sandler, on the safety and efficacy of proprietary medical devices and how often open-source software are more likely to be safer and better over time, and about what kind of organization the Software Freedom Conservancy is and how it helps open-source projects like Selenium continue to live on for the long-term)
  • Stop Inspecting, Start Glancing (by Dan Gilkerson, on automating web apps without looking at the DOM structure)
  • Transformative Culture (by Ashley Hunsberger, about moving from QA to Engineering Productivity and the culture changes necessary for getting better at testing)

Lessons from Timothy Ferriss’ “Tools of Titans”

Tools of Titans” is Timothy Ferriss‘ latest book, compiling lessons he has learned from interviewing over 200 world-class performers in his ‘The Tim Ferriss Show’ podcast. It is massive, and the number of takeaways he’s given away in the book is as plenty as it’s size. Like his “The 4-Hour Workweek” title, several of the ideas in it got me thinking deeper into how I’m living my own life, asking myself which projects and goals actually matter. Plus there’s bonus notes on other interesting things, like physical exercises that provide bang for the buck and the profound effects of using psychedelics in healthy doses.

Some favorite lessons:

  • The quality of your questions determines the quality of your life.
  • Do your kids remember you for being the best dad? Not the dad who gave them everything, but will they be able to tell you anything one day? Will they able to call you out of the blue, any day, no matter what? Are you the first person they want to ask for advice?
  • If you don’t do something well, don’t do it unless you want to spend the time to improve it.
  • Accept that quality long-term results require quality long-term focus. No emotion. No drama. No beating yourself up over small bumps in the road. Learn to enjoy and appreciate the process. This is especially important because you are going to spend far more time on the actual journey than with those all too brief moments of triumph at the end.
  • It’s not what you know, it’s what you do consistently.
  • When you’re thinking of how to make your business bigger, it’s tempting to try to think all the big thoughts, the world-changing, massive-action plans. But please know that it’s often the tiny details that really thrill someone enough to make them tell all their friends about you.
  • If this were the only thing I accomplished today, would I be satisfied with my day? Will moving this forward make all the other to-dos unimportant or easier to knock off later?
  • You can sacrifice quality for a great story.
  • People who have plenty of good ideas, if they’re telling you the truth, will say they have even more bad ideas. So the goal isn’t to get good ideas; the goal is to get bad ideas. Because once you get enough bad ideas, then some good ones have to show up.
  • The way you teach your kids to solve interesting problems is to give them interesting problems to solve. And then, don’t criticize them when they fail. Because kids aren’t stupid. If they get in trouble every time they try to solve an interesting problem, they’ll just go back to getting an A by memorizing what’s in the textbook.
  • Commit, within financial reason, to action instead of theory. Learn to confront the challenges of the real world, rather than resort to the protective womb of academia. You can control most of the risks, and you can’t imagine the rewards.
  • Choose projects and habits that, even if they result in “failures” in the eyes of the outside world, give you transferable skills or relationships.
  • For anything important, you don’t find time. It’s only real if it’s on the calendar.
  • When deciding whether to commit to something, if I feel anything less than “Wow! That would be amazing! Absolutely! Hell yeah!”—then my answer is no. When you say no to most things, you leave room in your life to really throw yourself completely into that rare thing that makes you say, “HELL YEAH!”
  • Great creative work isn’t possible if you’re trying to piece together 30 minutes here and 45 minutes there. Large, uninterrupted blocks of time—3 to 5 hours minimum—create the space needed to find and connect the dots. And one block per week isn’t enough. There has to be enough slack in the system for multi-day, CPU-intensive synthesis. For me, this means at least 3 to 4 mornings per week where I am in “maker” mode until at least 1 p.m.
  • Don’t try to please anyone but yourself. The second you start doing it for an audience, you’ve lost the long game because creating something that is rewarding and sustainable over the long run requires, most of all, keeping yourself excited about it. Trying to predict what an audience will] be interested in and kind of pretzeling yourself to fit those expectations, you soon begin to begrudge it and become embittered—and it begins to show in the work. It always, always shows in the work when you resent it.
  • You can’t blame your boss for not giving you the support you need. Plenty of people will say, ‘It’s my boss’s fault.’ No, it’s actually your fault because you haven’t educated him, you haven’t influenced him, you haven’t explained to him in a manner he understands why you need this support that you need. That’s extreme ownership. Own it all.
  • The world is this continually unfolding set of possibilities and opportunities, and the tricky thing about life is, on the one hand having the courage to enter into things that are unfamiliar, but also having the wisdom to stop exploring when you’ve found something worth sticking around for. That is true of a place, of a person, of a vocation. Balancing those two things—the courage of exploring and the commitment to staying—and getting the ratio right is very hard.
  • Any great idea that’s significant, that’s worth doing, for him, will last about 5 years, from the time he thinks of it, to the time he stops thinking about it. And if you think of it in terms of 5-year projects, you can count those off on a couple hands, even if you’re young.
  • The way you do anything is the way you do everything.
  • To blame someone for not understanding you fully is deeply unfair because, first of all, we don’t understand ourselves, and even if we do understand ourselves, we have such a hard time communicating ourselves to other people. Therefore, to be furious and enraged and bitter that people don’t get all of who we are is a really a cruel piece of immaturity.
  • It’s better to be in an expanding world and not quite in exactly the right field, than to be in a contracting world where peoples’ worst behavior comes out.
  • In any situation in life, you only have three options. You always have three options. You can change it, you can accept it, or you can leave it. What is not a good option is to sit around wishing you would change it but not changing it, wishing you would leave it but not leaving it, and not accepting it. It’s that struggle, that aversion, that is responsible for most of our misery.
  • Perhaps I didn’t need to keep grinding and building? Perhaps I needed more time and mobility, not more income? This made me think that maybe, just maybe, I could afford to be happy and not just “successful.”

Playing with Excel Files in Ruby Using Roo and Write_XLSX

Because of a small tool pitch I gave to our technical writer, I had a chance to play with Excel files through code for several hours last week. I have not done that before, but I felt that it was a pretty easy enough challenge as I have worked with CSV files in the past and thought that the experience would be something similar. I knew I just have to find out what existing libraries I could take advantage in order to build what I thought the program should be capable of doing, which is basically reading two Excel files, comparing them, and creating a new file with updated data based on both files.

Some googling brought me to the ruby gems Roo and Write_XLSX.

Roo helped with reading Excel files, and we can do this by:

xlsx = Roo::Spreadsheet.open(FILE_PATH)
xlsx = Roo::Excelx.new(xlsx)
spreadsheet = xlsx.sheet(SHEET_NUMBER)

Once we have access to a desired Excel file, we can get whatever data we need from it:

spreadsheet.each(column_data_1: COLUMN_NAME_1) do |info|
    // do something with information
end

After that, it’s just a matter of what information do we want to retrieve and manipulate from desired files. I mostly like to use arrays and hashes from here on.

As for creating new Excel files, we can use write_xlsx:

workbook = WriteXLSX.new(FILE_PATH)
worksheet = workbook.add_worksheet
worksheet.write(ROW_NUMBER, COLUMN_NUMBER, INFORMATION)
workbook.close

These two libraries can actually do more. Roo has an interesting read/write access with Google spreadsheets using roo-google. Write_XLSX on the other hand have formatting features we can leverage for better looking Excel outputs. I didn’t have to use those functionalies for the current test project though so I’ll leave those for another time.

Takeaways from Scott Berkun’s “The Dance of the Possible: The Mostly Honest Completely Irreverent Guide to Creativity”

How does one become a creative person? Are we only being creative when we’re delving into the realm of the arts? Why do we say that some people are more creative than others? Does creativity contribute to success? We admire accomplished illustrators, actors, programmers, singers, writers, painters, dancers, poets, and designers of all kinds because of their creativity in their chosen fields of endeavor, because we feel they have good taste in whatever it is that they do, and often we desire to be like them, wishing to churn out great pieces of work too in our lifetimes. But what does it really take to be creative? Scott Berkun gives his take on his latest book,  “The Dance of the Possible: The Mostly Honest Completely Irreverent Guide to Creativity“.

Personally, I don’t think much about what it means to be creative. I feel that thinking about its meaning doesn’t practically help me, because I’ve learned through experience that that only way to create good work is to do it, failing multiple times, learning along the way, and then succeeding. That’s what creativity has always meant for me – building things or solving problems that matter (to me or to other people I provide service to), whenever the itch is there or if the problems bug me enough. And reading Scott’s book felt like a confirmation of some sort of the beliefs I’ve had about creativity, plus a reminder to handle some of my habits better.

Here are some favorite lines from the book:

  • It’s far wiser to think about the effect you want an idea to have. If the goal is to make someone laugh, fix their car or increase the revenue of the widgets their company makes, that matters far more than how “creative” an idea is or is not.
  • We always have more freedom than we think, we just forget. We spend so much time trying to be efficient that doing anything interesting feels like a waste of time. And in this tendency is another misconception: creativity is rarely efficient. It always involves taking chances and trying things that might work but might not. The question then is: are we willing to spend time to be interesting, to think interesting thoughts and make interesting things? We all have the power, but perhaps not the willingness.
  • To create means to make something new, at least for you, and to do something new is like going off of the map, or more precisely, deliberately choosing to go to a part of the map that is unknown. In this case it rarely matters where or how you start.
  • You will, no matter how talented you are, have your finished works challenged and called not-so-good names. Good is surprisingly subjective, and the more creative the domain you work in, the more subjective it is.
  • The ability to see an idea, or a thing, from many different perspectives is among the greatest assets a thinking person can have. Of course you don’t have to agree with someone else’s perspective, but you owe it to yourself to try to see what they do. They may see something important you’ve never noticed before, however small, that can improve what you’re making or what you make in the future.
  • I don’t know a single productive creative person who doesn’t have a scrap pile of unfinished projects at different states of completion. This is not waste, but a precious archive of projects that might need to breathe, or of spare parts that may be perfect for other projects.
  • Some movies and books are poorly received when they’re released but become popular decades later. Others are big hits at first but fade over time. What is good? The answer depends on what your goals are and what problems you choose to solve.
  • No matter how great your idea is, there will be energy you have to spend, often on relatively ordinary work, to deliver it to the world.
  • Take pleasure in making things for the sake of making them: what a gift to have the time to make at all! If you were born 200 years ago, or to different parents in a different country, you wouldn’t have the time to feel bad about your work, because you wouldn’t have the wealth and time required to try. If you feel love for your craft, honor it by showing up, even when it’s hard. Especially when it’s hard. Working when it’s hardest often teaches rare lessons that will earn you easy rides now and then. Take pleasure in small progressions when you see them, and know those hard-won gains are the only way anyone in history has ever achieved anything noteworthy—for themselves or for the world.
  • If you truly love your craft, there is an infinite number of projects in your future. There will be other chapters. There will be other canvases and other songs. Perfection is a prison and a self- made one. Whatever you’re making, it doesn’t have to be perfect. Perfection is an illusion.
  • Expect to be rejected. You will be. It will happen no matter how successful you are.
  • Do one project for commerce and one for art. It’s an interesting approach: maybe the best work can only be made if it serves only one master at a time. It’s a healthy exercise to both make something entirely for yourself and entirely for other people. In each case you will stretch your boundaries for what you are capable of, as so often those conflicting desires of satisfying ourselves and satisfying other people bind us to conservative choices.
  • Too often we are distracted away from what we say is important by things that are more pleasurable or convenient. This means a central skill any creative person needs is a mastery of time, which means a mastery of habits. There will always be easier things in our lives than creative work. There will always be demands on our time that are more logical and lucrative than chasing an idea. If you are truly passionate about something you must be willing to make sacrifices to make it possible. What good is that passion if you can’t use it to help you do the work? Merely saying you are passionate, or feeling passionate, is not enough.
  • The simplest habit is to work on your project every day. If you don’t have a project, go to your private journal or drawing notebook daily until you do. It can be for ten minutes or an hour, but you must touch the work at least once a day. It can be in the morning, or late at night, or during your lunch break at work. At first when and where won’t matter. All that counts is that you commit to the discipline of honoring your ideas.
  • We all have the same time limit of 24 hours every day, which means the difference between a productive creative person and an unsatisfied dreamer is in how they choose to use it. Most of us forget how much of our time goes to entertainment, things we do purely for pleasure. We have plenty of time—it’s just we have to protect it for the things we claim are most important.
  • “Will anyone care about my work?” people often ask. Yes—you. It starts with you.

Favorite Talks from Agile Testing Days 2016

One of the great ways to be updated with what’s happening in the testing community is to attend software testing conferences, talk to the speakers and attendees, and ask questions. But if you don’t have the budget to fly over to where the conference is (like me), the next best thing is to wait for the conference recordings to be uploaded online. That’s how I’ve kept up with the latest news in test automation, following both the Selenium Conference and Google’s Test Automation Conference. All these recordings on YouTube paints a picture of what experiences and opportunities are currently out there for software testers.

And recently, I decided to free some time to follow Agile Testing Days and see what went on over at Potsdam, Germany. It was my way of checking out what’s happening in the agile testing community someplace far away from where I am. And today I’d like to share some of my favorite talks from that event:

  • Designed to Learn (by Melissa Perri, about testing product ideas, experiments and safe spaces for them, and learning what customers want and need)
  • Snow White and the 777.777.777 Dwarfs (by Gojko Adzic, about factors that may likely change testing policies and practices in the coming years as a result of computing power getting cheaper, such as third party platforms, per-request payments, multi-versioning, machine learning, mutation and approval testing, testing after deployment and failure budgets)
  • Continuous Delivery Anti-Patterns (by Jeff ‘Cheezy’ Morgan, on eliminating branches, test data management, stable environments, and keeping code quality high)
  • NoEstimates (by Vasco Duarte, about leaving out estimation in software development projects)
  • From Waterfall to Agile, The Advantage Is Clear (by Michael ‘The Wanz’ Wansley, on software testers being gatekeepers of quality, growing up in a waterfall system, and the wonderful experience that is software testing)

Lessons from Richard Bach’s “Illusions: The Adventures of a Reluctant Messiah”

Richard Bach’sIllusions: The Adventures of a Reluctant Messiah” is a most treasured book from all the books I have read so far. It is a short book, something that can definitely be digested for an hour or a few, but it doesn’t fall short of inspiring and thought-provoking passages, and questions. I have always kept a copy close because it’s what I often choose to rummage through whenever I feel totally sluggish or disheartened, never failing to provide a good pick-me-up or occasionally giving a disapproving eye when needed.

Here are some favorite lessons from the book, which I remind myself every now and again:

  • Learning is finding out what you already know. Doing is demonstrating that you know it. Teaching is reminding others that they know just as well as you. You are all learners, doers, teachers.
  • The simplest questions are the most profound. Where were you born? Where is your home? Where are you going? What are you doing? Think about these once in a while, and watch your answers change.
  • You are led through your lifetime by the inner learning creature, the playful spiritual being that is your real self. Don’t turn away from possible futures before you’re certain you don’t have anything to learn from them. You’re always free to change your mind and choose a different future, or a different past.
  • There is no such thing as a problem without a gift for you in its hands. You seek problems because you need their gifts.
  • The bond that links your true family is not one of blood, but of respect and joy in each other’s life. Rarely do members of one family grow up under the same roof.
  • If you learn what this world is, how it works, you automatically start getting miracles, what will be called miracles. But of course nothing is miraculous. Learn what the magician knows and it’s not magic anymore.
  • Isn’t it strange how much we know if only we ask ourselves instead of somebody else?
  • If you will practice being fictional for a while, you will understand that fictional characters are sometimes more real than people with bodies and heartbeats.
  • Like attracts like. Just be who you are, calm and clear and bright. Automatically, as we shine who we are, asking ourselves every minute is this what I really want to do, doing it only when we answer yes, automatically that turns away those who have nothing to learn from who we are and attracts those who do, and from whom we have to learn, as well.
  • The world is your exercise-book, the pages on which you do your sums. It is not reality, although you can express reality there if you wish. You are also free to write nonsense, or lies, or to tear the pages.
  • Within each of us lies the power of our consent to health and to sickness, to riches and to poverty, to freedom and to slavery. It is we who control these, and not another.
  • There is no good and there is no evil, outside of what makes as happy and what makes us unhappy.
  • If you want freedom and joy so much, can’t you see it’s not anywhere outside of you? Say you have it, and you have it! Act as if it’s yours, and it is!
  • We are game-playing, fun-having creatures, we are the otters of the universe. We cannot die, we cannot hurt ourselves any more than illusions on the screen can be hurt. But we can believe we’re hurt, in whatever agonizing detail we want. We can believe we’re victims, killed and killing, shuddered around by good luck and bad luck.
  • Why are we here? For fun and learning. It’s the same reason why people see films, for fun or for learning or for both together.

Fun fact: One of Richard Bach’s sons is James Marcus Bach, a software tester.
