Can you tell us a little about yourself (hobbies, education, etc):

I grew up in Chicagoland in the 80s, was on BBSes in the early 90s, and IRC in college and thereafter. I’ve been once to the Recurse Center in New York, twice to Holland, and six times to Bruno’s in Gerlach, NV. I like crossword puzzles, board games, and point-and-click adventures. One day I’d like to finish my “board simulation” of the awe-inspiring mechanics inside mitochondria. Continue reading PyDev of the Week: Saul Pwanson

Can you tell us a little about yourself (hobbies, education, etc):

I am a Middle School Computer Science Teacher and a Technology Integration Specialist. I have been teaching for 23 years and have taught in the US, UK and in Peru. I have a Masters in Curriculum, Instruction and Technology, which means I know a lot about how to teach and invent cool lessons. Besides working and co-hosting Teaching Python, I spend most of my time with my two boys outside playing sports in the south Florida sun. Continue reading PyDev of the Week: Kelly Schuster-Paredes

Can you tell us a little about yourself (hobbies, education, etc):

I graduated with a masters degree in statistics from Rice University in Houston, Texas in 2006. During my degree, I never heard the phrase “machine learning” uttered even once and it was several years before the field of data science became popular. I had entered the program pursuing a Ph.D with just six other students. Although statistics was a highly viable career at the time, it wasn’t nearly as popular as it is today.

After limping out of the program with a masters degree, I looked into the fields of actuarial science, became a professional poker play, taught high school math, built reports with SQL and Excel VBA as a financial analyst before becoming a data scientist at Schlumberger. During my stint as a data scientist, I started the meetup group Houston Data Science where I gave tutorials on various Python data science topics. Once I accumulated enough material, I started my company Dunder Data, teaching data science full time. Continue reading PyDev of the Week: Ted Petrou

PyDev of the Week: Sebastian Steins

Sebastian Steins

Can you tell us a little about yourself (hobbies, education, etc):

I am a software developer from Germany and live close to the Dutch and Belgian border. The internet emerged when I was in school. I have always been fascinated by computers and wanted to learn to program. Unfortunately, this was not so easy at the time, and I did not have teachers who could have supported me in that matter. It changed, however, when I got my first modem. The internet opened a whole new world for me, and I started to learn HTML, Perl and later, PHP. I built CGI scripts and small web apps back then, and it was really fun. Eventually, I took programming as my career path, although I sometimes struggled with that decision. Besides my degree in computer science, I also heard lectures on economics and had a few positions in the finance sector early in my career. Now, I enjoy coaching teams of great software engineers in architecture matters and try to pass my knowledge to junior devs.

When I’m not in front of a computer, I like to ride my road bike, learn new stuff from audiobooks and would never say no to a night out in a good restaurant. Continue reading PyDev of the Week: Sebastian Steins

Adding Notifications to Long-Running Jupyter Notebook Cells

If you use Jupyter Notebook to run long-running processes, such as machine learning training, then you would probably like to know when the cell finishes executing. There is a neat browser plugin that you can use to help solve this issue called jupyter-notify. It will allow you to have your browser send a pop-up message when the cell finishes executing.

The notification will look something like this:

jupyter-notify sample image

Let’s learn how you can add this notification to your Jupyter Notebook! Continue reading Adding Notifications to Long-Running Jupyter Notebook Cells

Two New Typosquatting Libraries Found on PyPI

Two new malicious packages were found on the Python Packaging Index (PyPI) that were designed to steal GPG and SSH keys according to ZDNet. The packages were named python3-dateutil and jeIlyfish where the first “L” is actually an I. These two libraries mimicked the dateutil and jellyfish packages respectively.

The fake python3-dateutil would import the fake jeIlyfish library which housed the malicious code that would attempt to steal GPG and SSH keys. While both of these libraries have been removed from PyPI, this is just another reminder to always be sure that you are installing the right package.

For full details, check out the ZDNet article as it breaks down how the libraries work.

Can you tell us a little about yourself (hobbies, education, etc):

I am a software developer currently working at Oracle in the Global Construction Engineering group. But I am probably better known as co-founder of PyBites, a community that masters Python through code challenges.

I have a business economics background. After finishing my studies in 2004 though, I migrated from Holland to Spain and started working in the IT industry. I got fired up about programming. I taught myself web design and coding and started living my biggest passion: automate the boring stuff making other people’s lives easier.

When not coding I love spending time with my family (dad of 2), working out, reading books and (if time allows one day) would love to pick up painting and Italian again 🙂

Can you tell us a little about yourself (hobbies, education, etc):

I was born in Buenos Aires, Argentina. Shortly after graduating from college with a Masters degree in Computer Science I was lucky to be offered a job in the United States, so I relocated to Portland, Oregon with my wife. We raised a family there and lived happily for several years. In 2018 we relocated once again, this time to Ireland. We plan to spend a few years on this side of the pond to be closer to my wife’s family and to be able to travel through Europe, but Portland is still our home and I’m pretty sure we will eventually return to America.

In terms of hobbies I have to say that by all standards I’m a fairly boring person. Outside of coding (which I do professionally and also as a hobby), what I enjoy the most is playing the Ukulele. I have a small collection of them, and I have recently expanded it with a Mandolin, which seemed appropriate now that I’m in Ireland. Everyone here seems to be in a band of some sort, so maybe one day I’ll join one as well, who knows! Continue reading PyDev of the Week: Miguel Grinberg

Can you tell us a little about yourself (hobbies, education, etc):

I’m 46 and happily married with 8 kids. Born and raised in South Central L.A. I joined the California National Guard while I was still in high school. I went to Basic Training between my 11th and 12th grades; came back and graduated with honors and was gone within the month for Advanced Initial Training where they taught me how to fix helicopter radios. After a couple of years I decided to enlisted full-time in the regular Army and did a stint for another 8 years in Automated Logistics and got an honorable discharge as a Sergeant in 2001.

Before getting out, I got in a semester of full-time college as part of a re-enlistment bonus. I loved it and I hit the books pretty hard. I was so pumped to learn that I pushed myself to continue to grow when I went back to work. As a result, I was able to get my MCSE, MCP+I and A+ certifications which allowed me to get into the role that I still hold as a Senior Field Engineer for Fidelity. I’m contracted out to one of our many customers, PNC Bank, at their Dallas lockbox location. The title has changed over the years but it entails a lot of hardware and software support. In case you don’t know, a lockbox is where everyone’s checks go for processing when they make a payment over snail mail. Everything gets imaged front and back and entered into the bank’s system and the banks customers can access their documents through a secure proxy connection immediately. The money transfers are made the next day once the checks have cleared. At the end of the month, the banks customers images are placed on encrypted CD’s or DVD’s and mailed out to them.

To blow some steam I like to play Minecraft with my kids, edit movies, play Beat Saber, take online courses, and do some Python coding. Continue reading PyDev of the Week: Martin Uribe
