People think that children grow the most when they’re babies, but for me, it was my 15th year on this planet. A lot of different events and decisions led my year to be amazing, and I'm going to try and sum up the best ones in this post (with pictures!).

December 16th, 2014: First Tomorrow JLM meetup

Max Voloshin, the event’s organizer, and me

Yeah, I know it’s not technically part of the year, but it’s part of the story. A bit more than a year ago, Max Voloshin, an 18-year-old student from Jerusalem, decided he wants to organize a meetup for entrepreneur teenagers in Jerusalem, and without knowing he started a large community in the city, which continues to grow and connect even without him. …

I didn’t even say that. Neta-Lee Hershlag, who you probably know better as Natalie Portman, did — but when I read that quote, another one popped into my mind — Churchill's more famous quote, “I am always ready to learn although I do not always like to be taught.”

Both quotes remind us that learning by ourselves is always more efficient and satisfying than listening to someone else trying to put knowledge inside our minds.

This is why most students today don’t enjoy school, and why most schools today fail to engage their students with the subject being taught.

Indiana University’s High School Survey of Student Engagement (HSSSE), reached more than 81,000 in the US. [source]
They found that 30 percent of the students are bored due to lack of interaction with teachers.
75 percent report material being taught is not interesting.
73 percent said, “I didn’t like the school.”
61 percent said, “I didn’t like the…

They said code is poetry.
I never got that sentence,
As if writing code is
Writing poetry.

But it turns out they were right.
Writing poems is easy, just like this one.
It’s mostly
Cutting sentences
In the middle,
Like a keyboard
In which the
Enter key
Is stuck.

Writing good poems, though,
Is much harder.
Just like writing good code.

Writing good,

That’s it.

About two and a half years ago I started using Dropbox for storing my work. It was about the time when I bought my second computer, and I wanted to have the ability to work and sync my files across both of my computers.

I joined Dropbox because it seemed friendly, easy to use and cooler than the alternatives. Of course, I also used Google Drive, OneDrive (MS), MEGA and others, but Dropbox always was my main cloud with my most important files. I did everything I could do for free to gain more storage space (Invited a couple of friends, tweeted about them, installed the program on all of my computers…) and eventually I got 5.6 …

Only human stupidity and sleepless developers.

A couple of weeks ago I had a conversation with a client. The website I built for him had a PHP script that sends emails to his email address whenever a user submits the contact form, and he called me and said he’s not receiving the emails.

When I heard it, unfortunately, my first reaction was, “Really? That’s weird. Let me check what’s wrong with the code”. I assumed that if he’s not receiving the emails, the problem is probably with the server or the code.

So I went to check what’s wrong. I did the QA by myself and tested again and again the little bit of code, suspected the hosting company, almost reconfigured the SMTP server, and still the client didn’t receive any of my emails. …

Me at my first event, “Tomorrow JLM”

How organizing a meetup changed my life.

Back in June 2013, when I was 13 (the advantage of being born on 2000 is that you always know how old you were at a certain date), I attended my first “Meetup”, or a tech-entrepreneurship event. It was a small event downtown Jerusalem, hosted by the “Startup Hub” [RIP]

Me at the first meetup I ever went to (first from the left)

Exactly two years later, June 2015: After being in Max Voloshin’s event for teenagers, I decided to follow his lead. …

How I created the best task management list in 20 minutes.

TODO: Read this article.

Today, people focus on so many things. Take a look at your TODO list: how does it look? If you really use it, I bet it has lots of items and tasks, waiting to be completed.

What ever happened to doing one thing at a time? This is exactly why today, about an hour ago, I decided to make the best, most useful TODO-list app.

This is Shortest.

A couple of days ago I was discussing different task management tools with Roy and Shalom, and at some point I showed them …

A Todo list and a calendar like you’ve never seen it before, in Accomplish!

We are all human (Except you, Google bot… I know you’re reading this!). We all make mistakes. We all get tired. We all postpone things to tomorrow.
We all have problems accomplishing things.

Tomorrow is often the busiest day of the week

Believe me, I’ve tried them all. Google Tasks, Google Keep, Any.Do, Wunderlist, Todoist, SolCalendar and many more. They’re all good. They all look beautiful, they all seem cool, nice, easy to use and perfect for you. For about a week. And then you stop making tasks, and then you stop doing tasks, and then you stop using it at all. …

Learn from my mistakes, rather than yours…

I’m Reuven Karasik, 15-year-old web developer. I’ve been programming since I was 7, but I only started charging money for programming in the spring of 2013.

So I started “having clients” (charging money for programming) around 2 years ago. Today, after many clients, many mistakes, and many wrong decisions made over those couple of years, I just wish I could go back in time and tell myself a few things that could’ve made my life easier. …
