The Blog

New blog post every Wednesday! I write regularly about technology, communities and life around me. I aim to publish a new blog post each Wednesday. If you wish to get notified when new posts arrive, I have a RSS feed you can subscribe to.

I've also visited a few podcasts which you can find on my speaking page.

For my longer pieces, check out Humane Tech Guides.

In addition to these posts, I wrote a blog in Finnish about my year in San Francisco back in 2014. It lives on it's own page at https://hamatti.org/unelma.

  • Embracing failure

    When I grew up, failing or being wrong wasn't something that was encouraged. It led to me only wanting to try things I already knew I'd succeed in. It took me until my late 20s to realize that it's hindering and slowing me down a lot. Luckily, I learned to start failing.

  • Advent of Code #2: Borrows, unwraps and lots of compiler errors

    Days 2 to 8 of Advent of Code and my journey with Rust was like 2020 on a very small scale: a rollercoaster of emotions. Some days I felt really good and enjoyed learning and coding and some other days I felt like I knew nothing about Rust and couldn't figure out the problems at all.

  • Advent of Code #1: Getting Started

    Advent of Code is an annual programming challenge that contains multiple small code puzzles each day leading up to Christmas. For me, they are a way to brush up old tech or learn something new. This year, I'm learning Rust for the first time.

  • Developers do design — but we’re not taught it

    In many companies, most of the days we developers end up doing design choices. Whether it’s graphic or service design, by the virtue of building things we make design decisions. But most developers are not taught design, not even the very basics.

  • City Bound Nomadic

    In the near future (say, within the next 5 years), I want to explore the possibilities of a digital nomad lifestyle. Working independently of location and time is a compelling idea and having followed digital nomads in blogs and Youtube and Instagram for quite a while, I’d definitely love to give it a try. Seeing the world, learning about new cultures and being able to experience the wonders that the world has to offer — sounds good, right?

  • The Reset Button

    Look around you. Of all your things, how many of them were a result of a thought-out process? And how many are just a result of an accumulation that started when you were a teenager?

  • The Cost of a Purchase

    Last week I had an interesting conversation with a friend. We started talking about minimalism and getting rid of excess stuff as she was moving to a new apartment.

Back in the day I was mostly measuring everything by their monetary value - do I have enough euros or dollars in my bank account to make this purchase.

  • Space has a Tendency to Fill Itself

    An average US household has 300,000 items. I would argue that it’s a lot. But looking at my own childhood in Finland, it’s actually not surprising. We tend to gather a lot of stuff. And there’s a perfectly reasonable explanation for it - space has a tendency to fill itself.

  • My love-hate relationship with PHP Arrays

    I’ve been programming PHP for most of my life, almost 20 years now. While PHP has many downsides, horrible history, and terrible reputation, it has improved a lot with PHP 7 and modern frameworks like Laravel that make it really enjoyable to develop.

  • Beginning of a Journey

    My journey as a minimalist started a year ago. For quite a while I had been a fan of the Tiny House movement and sometime last summer I ended up watching Youtube videos about minimalism and quickly found out about The Minimalists.

    About a year ago I learned about minimalism from Youtube videos and the two dudes who call themselves the minimalists. In the end of June last year, I wrote a blog post about the first steps in my journey. After having a fruitful discussion about the topic with a friend on Wednesday, I decided to write a follow-up based on my experience and learnings from the past year.

  • Do you want to learn new stuff?

    Continuous improvement, life-long learning, staying on top of your game are all things very close to my heart. It's not always easy though. Sometimes your life (personal and professional) takes a detour and you end up in a situation where your skills get rusty.

  • Food Connects People - How to Hack Your Community with Food

    One of the things I learned early on was that everybody has to eat. Most people eat lunch and it means taking a “mandatory” break from work and the busy-ness of business life. I’ve used that knowledge to my advantage by making a lot of connections by asking people for lunch. They don’t have to make room for meeting me and people are often happier when they eat.

  • Communities in Marketing

    Communities are fantastic, I love them. We have had communities for as long as humans has been in existence but in the past few years, it has become a buzz word.

We started Turku ❤ Frontend a couple of years ago with the aim to help people learn new skills, meet fellow developers and make it easier for professional developers and students to find jobs and thus, making it easier for companies to find local talent.

  • Improve the world — help someone learn

    We all have skills that other people lack. Whether it’s programming, knitting, writing, fixing bikes or cooking delicious food, you are better doing it than someone else. And while everyone of us is good at something, we also crave to learn new skills to improve our lives.

  • Intentional and multifunctional - How I got rid of most of my belongings

    I have a background as a hoarder. I lived my childhood in a big suburban home and we threw away almost nothing.

But eventually I realized the problem was my huge piles of junk.

  • If you are not doing code reviews, start now!

    I was introduced to code reviews few years back in my first startup job and as a junior developer I immediately felt their impact. Having my code reviewed by seniors and reviewing code myself taught me a ton. After that job, I switched to another startup and we had a great code review process in place as well. I thought world was a good place.

    Recently I’ve been talking a lot with different people about communities, community management and different aspects related to it. One of the key differences in how people view communities is what I call professional-leisure divide. (I hope one day I’ll have a better word for it.)

  • Build your community like a garden

    I have recently found interesting parallels in building and managing communities and gardening. Understanding those parallels and learning from the ancient art of gardening can provide tools for effective community management.

  • What Rails Girls taught me about non-organizations

    Finland is the promised land of organizations. Almost every citizen is or has been part of a non-profit organization during their life and most of us have been a board member in one or two or … well, let’s just say some of us do it a lot.

  • Building a developer community calls for strong support

    Almost everyone who’s been in touch with crowdfunding in a form or another or has seen a talk about it, knows the classic 4 F’s. Friends, Family, Fools and Fans. I’ve learned that in some sense, it applies to so much more than just crowdfunding.

  • 8 hours later + Turku <3 Frontend Hackathon

    Turku ❤ Frontend is a community of (mostly frontend) developers in Turku region that was started in December 2015. Between September and May, we organize meetups at local companies’ offices with talks and beers and during the summer break we just finished our first hackathon.

  • Why I love hackathons

    I’m a huge fan of hackathons. Last weekend, I had the privilege to organize one for the first time after attending a few. Even though being super tired on Sunday evening after a long weekend of very little sleep on a couch, I was so happy being able to organize a successful event.

  • What's with all these sorts, PHP?

    A few days back I was ranting to my friends about PHP arrays. I’m not as much of a PHP hater as many but there’s still some things that really bug me. Everything to do with arrays is one of them. Let’s have a look. I use the phrase normal array to mean a non-associative array (like Python’s list or Java’s array).

  • Beauty of the Pipe

    The Unix Pipeline is a powerful and beautiful piece of software that is sometimes difficult to grasp for a command line beginner. We are used to use graphical interface apps that mostly only interact with each other by writing and reading files if at all. The concept of standard out (stdout) and standard in (stdin) are something that takes some time to learn and understand when one is learning programming and/or data tools in command line.

  • Case study - DataMonkey as educational platform

    A coworker of mine shared a link to DataMonkey, a platform/website to learn basics of data manipulation, Excel spreadsheets and SQL, the language used for database queries in relational databases like MySQL, PostgreSQL and SQLite. During my studies and personal exploration for the best practices in educational systems, I have encountered many that have been quite horrible (like TRAKLA2 which is used for teaching algorithms and data structures) and many that have a bit better approach (like Codecademy and and ViLLE system for teaching programming).

  • Adventures of a Junior Developer

    I had never had any real problems in starting a new summer job regardless of the field. I have been building elements for buildings, assembling phones, guiding kids in sport camps, selling home electronics and video recording sport events to name a few. But when it started to be a time to turn my education into a developer job in a real company, I had these weird feelings of fear and anxiety. It seemed that there were many processes and practices that everybody else just knew about and I had no idea.

  • The Beautiful Game

    Regardless of if you call it football or soccer, fans of the the Beautiful Game were in for a treat for the past month. After a 4-year long wait, FIFA World Cup filled the days of sports lovers all around the world. I love soccer and statistics so I collected some of the most interesting stories of this year’s cup.

  • Becoming a better programming teacher

    About a week ago I got an email through San Francisco Ruby Meetup Group about a workshop on becoming a better programming teacher and given my background and passion for education, it was a no-brainer to jump in. A four hour workshop was organized by General Assembly, a company that provides bootcamp like programs, part time courses, classes and workshops for everyone who wants to become a better developer or change their career into development.

  • Rails Girls San Francisco

    After coaching at Rails Girls Helsinki last November and getting a job in San Francisco, one of the first things I did was checking out if there would be a Rails Girls event here too. And how lucky was I. Last weekend, almost 100 enthusiastic girls and women took their laptops and came to Engine Yard for two-day workshop to learn about web development with Ruby on Rails. Since I already wrote about Rails Girls after the last event, I won’t dig too deep into what it is.

  • Command line magic with git and bash history

    So, in the beginning of January I started as an engineering intern in Chartio and since that my workflow has really improved a lot and I’ve learned and discovered some tricks.

  • Difficulties with teaching and learning programming

    It’s no secret that learning programming is – at least for some of us – an obstacle course. Personally, it took me years to grasp the skills to be a some-what good programmer. For the last 3 or 4 years I’ve been involved in teaching programming basics for freshmen in my university. I started with helping fellow students, then started as a mentor for department and nowadays in addition to previous, I work as a part-time teacher on our courses.

  • Computer illiterate generations – what should we do?

    There has been a lot of discussions during the last years about the IT education of young people. Today, the topic once again popped out in Finnish news when Finnish Broadcasting Company wrote a news piece about the level of IT education in Finnish elementary schools.

  • Rails Girls – building the future

    Today was my first ever Rails Girls event in Helsinki. I ain’t much of a Rails or even a Ruby, I tend to choose Python as my weapon of choice. However, I’ve been long interested in Rails, done some hobby projects with it and even more than that, I’ve been into teaching new people to programming for couple of years now at the university. So coaching a Rails Girls event was super exciting new experience.

  • 69 Lines of SQL

    Sometimes I wonder what programming really is and why we hackers find it so compelling. Most of the time we – or atleast I – bang our heads to wall for hours while trying to conquer the challenge. After all those hearth-breaking moments we finally succeed to get the code running and it solves the problem. All the dark clouds disappear, flowers start to bloom and happy squirrels are jumping everywhere. I had one of these moments today while trying to do some SQL magic.

  • TDD Pair Programming at University

    Today was surprising day at the university. I’m taking a class called Designing Object-Oriented Software which has before been somewhat boring 7 x 90 min lectures and an exam but this year our professor hired a guy called Aki Salmi to organise 4 workshops á 4 hours. Beforehand I knew Aki is a guru and an excellent guy but I was still surprised to see how much fun studying at best could be.
