While the Tor Project and the Rak’n’Roll Foundation work in different areas, they share a common mission—empowering people with freedom. The Tor Browser ensures online anonymity and security, while the Rak’n’Roll Foundation helps people struggling with cancer regain the courage to live life on their own terms. Both initiatives fight for independence—one in the digital world, the other in the face of illness.

These projects will receive our financial support in February, thanks to Gabriel Spytkowski, an Unreal and C++ developer involved in the development of our product, theStore, a virtual shopping simulator designed for consumer research.

Rak’n’Roll Foundation – Fighting cancer with courage

Cancer is not a death sentence—it’s an obstacle that can often be overcome. The Rak’n’Roll Foundation works to break the cancer taboo, challenge stereotypes, and improve the quality of life for cancer patients by restoring their courage and helping them rediscover the beauty of life. Through initiatives like the well-known “Give Hair!” campaign, the foundation has gained widespread media attention and used bold advertising campaigns to bring the conversation about cancer into the public eye, changing how society views the disease.

Tor Project – True privacy online

For 19 years, the Tor Project has been protecting anonymity and privacy online, developing free, open-source solutions that keep users safe. They created the Tor Browser, which shields against online surveillance and enables access to otherwise restricted content. At the heart of the Tor Project is true freedom of speech online—even in countries where it is limited.

“This project is important to me because freedom of speech and privacy are fundamental rights that the Tor Project defends,” says Gabriel, explaining his choice.

In a month, we’ll be unveiling the next edition of our #SidnetDonations initiative, featuring new projects that will benefit from our support. Stay tuned!

A new year brings a new edition of the #SidnetDonations initiative! Check out which open-source project and non-profit organization will receive our support, as chosen by Gosia Łaszczych, our Office Manager.

The Office in Good Hands

The smooth operational functioning of Sidnet is largely supported by Gosia Łaszczych, who has been serving as Office Manager for over two years. Gosia is committed to managing administration, recruitment, employee-related matters, and organizing notable company events.

Sidnet Joins Forces with WOŚP

Supporting The Great Orchestra of Christmas Charity (WOŚP) is a long-standing tradition for Gosia. She regularly donates through bank transfers and by contributing to donation boxes during the organization’s annual finale. This year, thanks to Gosia, WOŚP will receive additional support by becoming the beneficiary of January’s #SidnetDonations initiative.

The 2025 WOŚP finale focuses on ensuring the safety and health of children, with funds going to pediatric oncology and hematology wards.

Would you like to join Gosia and Sidnet in supporting WOŚP? Here’s how you can help:

• Volunteer with the Peace Patrol
• Donate directly to WOŚP’s bank account
• Drop a donation into one of the many collection boxes across Poland

Thunderbird – An Office Manager’s Essential Tool

Gosia’s laptop is one of Sidnet’s command centers, and email is her most critical tool. It’s no wonder that this month’s #SidnetDonations support went to Thunderbird, a free and open-source email client developed by Mozilla Foundation.

Thunderbird is a must-have for office management, making it easy to organize emails and prioritize issues. Thanks to Gosia and Thunderbird, Sidnet’s operations stay seamless and chaos-free.

We’ve kickstarted another year of supporting impactful initiatives. Stay tuned—over the coming months, we’ll unveil more open-source projects and non-profit organizations set to receive our support!

December and the upcoming holidays are perfect times for the next edition of the #SidnetDonations campaign. This time, Kamil Głuszak, our indispensable Perl Developer and Team Leader, has chosen to support the Kundelek Dog Shelter in Rzeszów and the Open Source Initiative.

Five Years of Collaboration with Kamil

Kamil recently celebrated his fifth work anniversary at Centuran, a subsidiary of Sidnet Solutions. From the start, he distinguished himself as someone who embraces challenges and is always ready to take on even the most demanding tasks. His determination, perseverance, and leadership skills inspire the entire Centuran team.

We’re grateful for these shared years and excited about the milestones yet to come!

The Kundelek Dog Shelter – Helping Animals in Need

Kamil’s first choice is the Kundelek Dog Shelter in Rzeszów, which holds a special place in his heart. He remembers it from his school days when food drives were organized for the shelter. Next year, Kundelek (Mongrel in English) will celebrate 20 years of dedicated work helping animals. The shelter not only facilitates adoptions but also offers virtual adoption options.

Winter is an especially challenging time for shelters. Increased heating costs, shortages of warm blankets and bedding, as well as high-calorie food, pose significant challenges. That’s why Kamil decided to support Kundelek—to help provide animals with decent living conditions during the harshest months of the year.

Open Source Initiative – Supporting Free Software

The second beneficiary is the Open Source Initiative (OSI), an organization dedicated to advancing open-source software and supporting developer communities worldwide.

Kamil has been working primarily with open-source tools for the past decade, making this organization a natural choice for his support.

He especially appreciates OSI’s efforts to shape AI-related regulations, including the Open Source AI Definition, which emphasizes transparency, ethics, and reproducibility (interpreted as consistency in obtaining the same or similar results when using the same dataset and AI algorithm) in AI system development. This is a crucial step toward the responsible advancement of technology that transforms our lives.

We thank Kamil for five years of collaboration and for his thoughtfulness in choosing the organizations supported as part of #SidnetDonations! The new year is just around the corner, and with it, the next chapters of our initiative! Stay tuned!

November has arrived, bringing another opportunity to support those in need as part of the #SidnetDonations campaign. This time, Patryk has chosen the Open Cages Association and the Kolibri educational platform.

Third Anniversary at Sidnet

Patryk recently celebrated the third anniversary of our fruitful collaboration. During this time, he has established himself as a skilled Frontend Developer, with productivity and a work ethic that is second to none. He navigates React, NextJS, and TypeScript with remarkable ease and has an exceptional eye for detail—nothing escapes him, and projects are always polished to perfection.

Kolibri – Time to Say Goodbye to Educational Exclusion

Educational exclusion is a serious problem that hinders children and young people living in remote, poorly connected areas with limited access to educational materials. Kolibri, an open-source educational platform designed and managed by Learning Equality, aims to address this issue. Technology-based yet operating on an offline-first model, Kolibri provides a solution to gaps in educational access and the lack of internet connectivity.

Open Cages Association – A Chance for Animals

Industrial animal farming, while considered by many to be an essential part of the economy, is also an area where abuse and even crimes frequently occur. The Open Cages Association has set itself the goal of driving systemic changes and regulations to curb illegal and unethical practices in farming, ensuring the highest possible standards of animal welfare. At the same time, the association actively promotes a vegetarian lifestyle, educating the public that meat and animal products are not as essential to us as we have become accustomed to believing.

Soon, in December, we’ll have the holiday #SidnetDonations – join us in watching for the first star.

In October, on the occasion of his 15th work anniversary, Krzysztof Pisera decided on where the support from the #SidnetDonations campaign should go. The funds will be donated to the “Little brothers of the Poor” Association and the Python Software Foundation.

The Loyalty

In Sidnet’s 20-year history, there are still employees who have been with us almost from the very beginning and helped shape the first chapter of our company. This month, Krzysztof is celebrating his 15th work anniversary. Over the past decade and a half, he has repeatedly proven himself to be an excellent developer, a dedicated manager, and a responsible leader. For nearly half of that time, he has served as COO, ensuring that every process within Sidnet runs smoothly and without obstacles.

Python Software Foundation – The First Choice for Many

As one of the most popular programming languages in the world, Python is the go-to choice for many developers. It has had a tremendous impact on Krzysztof’s professional life, and even now, after many years, it remains his preferred language. Python is managed as an open-source system by the Python Software Foundation, which not only ensures the continuous development of its infrastructure but also provides a platform for a vast global community of users.

“Little brothers of the Poor” Association – Support for Lonely Seniors

The charitable organization receiving funds in October was part of our initiative many years ago. That support led to a partnership that continues to thrive to this day. Life in one’s later years is not easy, especially when old age is accompanied by loneliness. The “Little brothers of the Poor” Association was founded to support seniors struggling with feelings of abandonment. Regular visits from volunteers, a helpline, group meetings, and the “Gift a Christmas Eve” campaign, which has been running for two decades, help remind elderly people that they are not alone in this world.

In November, we will reveal more organizations that will benefit from the #SidnetDonations campaign – stay tuned!

As autumn approaches, so does the September edition of our #SidnetDonations initiative. This month, we’re proud to support two causes close to Dawid Jancen’s heart: the animal shelter in his hometown of Tczew and the continued development of the LibreOffice suite.

A Journey of Nearly a Decade

Dawid’s journey with Sidnet is a classic “from zero to hero” tale. Starting as a self-taught junior developer, he quickly rose through the ranks, earning recognition not just as a talented Web Developer with a flair for single-page applications, but also as a compassionate and helpful colleague. Since day one, Dawid has been a key player in our projects for one of our largest clients, THG, and he’s soon approaching a milestone – ten years with Sidnet!

LibreOffice – Empowering Everyday Office Work

While many businesses rely on paid office software, Dawid’s passion for open-source solutions has long made LibreOffice his top choice on both his work and personal devices. In his words, it’s an alternative that “more than meets the needs of most users in terms of functionality.”
LibreOffice is available in 110 languages, and if Dawid’s endorsement isn’t enough, consider that countless public institutions worldwide rely on the suite for their daily operations.

Helping the Four-Legged Friends in Tczew

This month’s donation recipient comes as no surprise – Dawid once again chose the animal shelter in Tczew, demonstrating his deep love for animals. The shelter depends on fundraising and volunteers, yet its needs often outpace the available resources.

You too can make a difference. Support the fundraiser organized by OTOZ Animals Shelter in Tczew. Your contribution will help provide food, medicine, veterinary supplies, life-saving procedures for injured animals, and much-needed improvements to the shelter’s facilities.

Stay tuned for October, when we’ll announce the next organizations to benefit from the #SidnetDonations project!
