Xceptance Supports Young Explorers with Donation to Witelo e.V.

The little Ozobot speeds around the corner, flashing colorfully, winds its way along a spiral, collides briefly with one of its colleagues and finally finds its way through the maze. It is navigated to its destination by color sensors on its underside, which allow it to follow a defined route. The miniature robot was not programmed by a high-tech engineer, but by Magnus, 10 years old, and the son of our co-founder Simone Drill.

During a programming workshop, he learned to give commands to the Ozobot and to control it with the help of color codes.  This was made possible by witelo e.V. from Jena, who offer working groups and experimentation courses at schools, as well as extracurricular learning formats. These scientific and technical learning venues were founded to promote so-called STEM education, with computer science as one of its components. Students learn the basics about coding, robotics and algorithms in research clubs, on hands-on days and during a wide range of vacation activities. In this context, Magnus also had the opportunity to playfully gain his first programming experience and took his enthusiasm from the workshop home with him.

Data Science Day 2022

After a two-year break, on 18 May 2022, the 4th Data Science Day Jena took place. The Friedrich-Schiller University is hosting this mini-conference format annually.

Xceptance presented this year a closer look at the data that is collected and processed during load and performance testing. René Schwietzke, Managing Director of Xceptance, talked about the challenges to capture the right data as well as translate the collected data into meaningful results. 

A load test simulates millions of user interactions with a website and therefore is capturing huge amounts of data points. These have to be transformed into a few numbers to make the result of the test easy to communicate but still preserve important details. The talk started with typical business requirements and expectations of the target groups of a load test. It showed the data XLT captures and the dimensions which later drive the data reduction. A few example data series demonstrated the challenges behind the data reduction and what numbers are finally used to satisfy the requirements.

An example load test result illustrated the talk with real data. That example test run created about 17,500 data rows per second which contain about 293,000 data points. The entire test result consists of 3.2 billion data points. This massive data set is turned into a consumable report by XLT in less than six minutes. 

For everyone with an interest in data science, this presentation also offers ideas for research in regard to unsolved data challenges. There might be even some Master’s and Bachelor’s theses topics waiting for you.

Xceptance at 11th Charity Relay in Jena

Yes, we did it again. We’re athletic and we care for our community, so we took on another sports challenge and had three of us participate in the 11th Relay Race in Jena, a charity run covering a 3x2km distance.

We had a lot of fun and did pretty well but most importantly we’re happy that this year’s funds will be donated to the Kindersprachbrücke Jena e.V., a local organization devoted to helping refugees and migrants, especially children and their families, learn German and find a new home in Jena.

Open-Air in Jena – kulturarena 2015

Logo KulturarenaWe are again supporting Jena’s widely acclaimed KulturArena Open-Air to contribute to local arts and culture. The international festival, which is held right in downtown Jena, is famous for hosting musical acts from all over the world.

This year’s performers include well-known artists such as Tanita Tikaram, Roachford, and Element of Crime. As always, visitors can also go to movie nights and theater performances. We’re excited to be a part of the biggest open-air event in Thuringia.

So come on out and enjoy exciting summer nights in Jena!

Xceptance at 5th Jena City Corporate Running Challenge

On May 20, 2015, we again joined Jena’s greatest sports and charity event, the Jena Corporate Running Challenge. Every year local companies and organizations go on a 5 kilometers run in downtown Jena to promote sporting activities and, more importantly, raise money for local programs and institutions devoted to help others in need.

We had a lot of fun and all of us tackled the whole distance. This year’s funds will be donated to various charity projects in Jena: the Paten für Demenz project for people with dementia, the mental health charity Aktion Wandlungswelten, and the Stiftung Hodenkrebs dedicated to research on testicular cancer.

Xceptance Goes by Bike

From May 9 – 29, the city of Jena hosts the so-called Stadtradeln event, a nation-wide campaign initiated by the Climate Alliance to foster climate protection and bicycle-friendly communities. Everyone is invited to get together in teams and compete for the most miles commuted by bike.

Banner StadtradelnA total of 46 teams is going to cycle in Jena and we are proud to announce Xceptance is one of them this year. Throughout the next couple of days we will therefore ditch our cars, get on our bikes as much as possible and track our miles as well as CO2 emissions saved. It is not that important to us where in the ranking we will end up: as an international company we still care about our local environment and we are happy to contribute in our own small way to climate protection and an eco-friendly Jena.

Videos of TEDxFSU Jena

About a month ago, we proudly sponsored the TEDxFSU event in Jena. Today, the videos of all talks came online and of course we want to share them with you, because the TEDx mission is free access to education. Enjoy: Videos of TEDxFSU Jena.

This is one of the talks in which Peter Perceval discusses the connection between humor and innovation.

Inaugural XLT Summit in Jena

On January 19-20, 2015, Xceptance held its first XLT Summit. About thirty representatives of well-known companies from a variety of fields, including finance, retail and eCommerce, all of whom use XLT to help them in developing web-based software applications, accepted our invitation to meet at Xceptance’s headquarters in Jena, Germany. The goal of the conference was to give XLT users the opportunity to discuss their experiences using our tool both with each other and with the internal XLT development team.

To kick things off, on January 19 we enjoyed a casual dinner in a local restaurant. The next day there was a varied program consisting of presentations contributed both by Xceptance colleagues and external users. Our customers reported on their practical experience using XLT, and had a chance to discuss their results with the other users. The many different applications of XLT–from load testing to test automation to application monitoring–were thus illustrated in light of actual day-to-day practice. A selection of these presentations can be found here: http://goo.gl/fPJj1Q, and parts of the presentation provided by our guests from OTTO.DE can be read here: http://dev.otto.de/.

In addition, the XLT development team presented the newest XLT features. Our guests had the opportunity to speak directly with the developers about their specific feature requests, some of which we were able to immediately agree to implement.

In short, the conference was a great success. In response to the overwhelmingly positive feedback from the participants, the XLT Summit will now be a regular annual event.

Last but not least, we would like to thank all the attendees, without whose engagement, interest and suggestions the event would not have been possible!
