Below you can find the talk abstracts

1. How to analyze your JVM application’s performance. Tools and techniques
Where my app consumes all the time? How much it costs in CPU time a current method execution in your production environment? Can there be any memory leak in your app? What is happening with garbage collection and allocation rates? Is there any deadlock?
This talk will focus on techniques and tools for gathering metrics from JVM applications. Using tools like JVisualvm(https://visualvm.github.io/) and Arthas(https://github.com/alibaba/arthas) to measure, analyze and improve our application’s performance.

2. Improve the quality of your software in 6 steps
Do your customers keep complaining about bugs in your software application? Does it take you too much time to implement new features?
If you answered yes, then you probably have issues with the quality of your software application. Here are 6 practical steps that you could follow, to improve its quality.

Γεια χαρά σε όλους και καλή Χρονιά!

Την Πέμπτη 31 Iανουαρίου στις 19.00 θα τρέξουμε το επόμενο Athens Python Meetup, στα γραφεία της yodeck (https://www.yodeck.com/) στην Ομόνοια (1ος όροφος), που προσφέρθηκαν να μας φιλοξενήσουν και τους ευχαριστούμε για αυτό.

Θα μας μιλήσει ο Παντελης Πετρίδης [0], Co-Founder της Elorus (https://www.elorus.com/), σχετικά με “Horizontal scaling using Sharding in Django”.

Όπως πάντα μετά το τέλος της ομιλίας θα υπάρχει χρόνος για να τα πούμε, να γνώριστούμε και να ανταλλάξουμε απόψεις πάνω στην Python 🙂

Τα λέμε εκεί!

Let’s talk about … Java Security, Testing practices and Team dynamics

Happy 2019 to everybody!

We set the bar high with our last talk of 2018, so we needed an equally challenging event for 2019.

So, we are welcoming 2019 with a mini-conference and presenters from three different countries and two different continents:-)

This time we will host three different talks

1. A talk on Java security architecture, by Martin Toshev, of the Bulgarian Java User Group and Software Architect at Resolve Systems

2. Agile Testing Practices, with examples on Java, by John Pourdanis, Test Automation Engineer, ISTQB Certified Tester working for Pheron LTD (of the SchooX group)

3. How (not) to produce Software, and the intricacies of the team by Dimos Madarakis, Software Engineer @Tokyo, Japan (tele-conferencing)

More details on each talk, will be added in the following week, but I hope you are intrigued enough to rush and secure a place in the meetup:-)

We will be especially happy to have participants from other meetups, or any working software engineers that would like to expand their horizons:-)

Cryptocurrency Social meeting (last of 2018)

Κοινωνική συνάντηση στο crypto-friendly μαγαζί “Dastart” (http://www.dastart.com — στον πάνω όροφο) για να “τα πούμε” μια τελευταία φορά πριν το νέο έτος !

Social meetup at “Dastart” (http://www.dastart.com — upstairs) to get to hang out one last time before the New Year!

Hope to see you there!

And Merry Christmas to everyone !!

Networking & Xmas drinks – Digital Analytics Meetup #12

Καθώς μπαίνουμε στις γιορτές είπαμε να κάνουμε μια συνάντηση διαφορετική από τις προηγούμενες! Πέμπτη, 20 Δεκεμβρίου βρισκόμαστε στο bar Έπαυλη Μαρόκκου (Βασ. Όλγας 133, πρώην αστυνομία). Θα είμαστε εκεί από τις 20:00 για να γνωριστούμε καλύτερα και να πιούμε ένα (ή και παραπάνω) ποτά όλοι μαζί.
Ελάτε να ανταλλάξουμε ιδέες για επόμενα meetup, να συζητήσουμε αυτά που σας άρεσαν ή σας απογοήτευσαν μέσα στην χρονιά αλλά και για να μάθουμε λίγο καλύτερα ο ένας τον άλλο.
Σε αυτή τη συνάντηση δεν θα υπάρχουν ομιλίες.

.NET Core 3.0. An evening with Scott Hanselman

The highlight of .NET Core 3 is support for Windows desktop applications, specifically Windows Forms, Windows Presentation Framework (WPF), and UWP XAML. You will be able to run new and existing Windows desktop applications on .NET Core and enjoy all the benefits that .NET Core has to offer.
Learn everything about it from Scott Hanselman (via Skype).

Συνάντηση 2018.12

Προγραμματίζουμε μια χριστουγεννιάτικη συνάντηση τον Δεκέμβριο.

Θα έχουμε 2 ομιλίες
* “Building a Flask application in Docker Swarm” by Transifex

* “A gentle introduction to Deep Learning using Keras” by Vladimir (Data Scientist at Warply) [0]

In this session, we will make a brief introduction to Deep Learning with a focus on using Convolutional Neural Networks for image classification.
We will be starting our journey in the mid-50s, with the invention of the perceptron, moving gradually onto multilayer neural networks, and finally into the recent advances in deep learning.
Next, we will briefly discuss some best practices used for deploying DL models to production and pushing them onto mobile devices.
Finally , we will code a Convolutional Neural Network using the Keras library.

No prior knowledge of Deep Learning or Keras is assumed.

Θα σας περιμένουμε στο hackerspace 🙂
