Master the logic of exhaustive exploration in this technical deep dive into Depth-First Search (DFS). This session is essential for developers aiming to sharpen their problem-solving skills and excel in coding interviews at top tech companies.1 You will learn how to navigate complex data structures by diving deep into a single branch of a graph or tree before backtracking, a strategy that is fundamental to advanced algorithm design.

We will explore the core mechanics of the Stack data structure and its role in managing the search path, whether through manual implementation or recursion. By understanding the "last-in, first-out" (LIFO) principle, you will gain a clear perspective on how DFS manages memory and state. We will also analyze time complexity and space complexity, giving you the tools to determine when this "depth-first" approach is more efficient than a "breadth-first" one.

The class also bridges the gap between theory and real-world applications. You’ll discover how DFS powers critical software functions like cycle detection in compilers, topological sorting for task scheduling, and even the logic behind automated maze solvers and puzzle AI.3 Seeing these graph algorithms in action will help you understand how to structure your own code to handle dependencies and complex nested relationships effectively.

By the end of this live session, you will be equipped with a robust framework for implementing DFS in various scenarios. We will practice identifying the specific software engineering problems—such as pathfinding in game AI or dependency resolution in package managers—where DFS is the optimal choice.4 This class is designed to elevate your algorithmic thinking and provide the practical confidence needed to tackle sophisticated engineering challenges.

Er komt weer een Unconference, samen georganiseerd door Code for NL en het Digitale Autonomie Competentie Centrum! Net als in 2020, 2023, 2024 en 2025 brengen we de Public Tech community in Nederland samen. Voor ontmoeting; een overzicht te krijgen van initiatieven; nieuwe samenwerkingen op te zetten; en digitale autonomie in Nederland te versterken! Zo wordt één misschien wel drie. Dit keer wordt het evenement gehost door de gemeente Amsterdam.

------- --------------------------------------------------------------------------- Heb jij al een idee voor een sessie? Laat het hier weten! https://pad.riseup.net/p/UnconferenceJan2026-keep ---------------------------------------------------------------------------

Unconference

Een unconference (of onconferentie in het Nederlands) is een bijeenkomst die lijkt op een conferentie, maar dan zonder het traditionele, vooraf vastgestelde programma. In plaats daarvan wordt de inhoud grotendeels bepaald door de deelnemers zelf, vaak op de dag zelf. Het draait om openheid, interactie en samenwerking. Het is niet helemaal open en chaos: er komen verschillende ideeën binnen van mensen die die dag iets verder willen brengen.

Kenmerken van een unconference:

• Geen vaste sprekers: Iedereen kan een sessie voorstellen, leiden of eraan deelnemen.
• Flexibel programma: De agenda wordt meestal aan het begin van de dag gemaakt, vaak op een whiteboard of digitaal bord.
• Deelnemers = bijdragers: Er is geen strikte scheiding tussen “sprekers” en “publiek” – iedereen is gelijkwaardig en mag input geven.
• Interactief: In plaats van lange lezingen draait het vaak om discussies, workshops of brainstormsessies.
• Leren van elkaar: Het idee is dat alle deelnemers waardevolle kennis en ervaring meebrengen.

Wat is Public Tech

Public Tech is (open) technologie waarin publieke waarden, zoals privacy, autonomie en transparantie, en publieke belangen uitgangspunten zijn. Public Tech ondersteunt het functioneren van een democratische samenleving waarin mensen elkaar vrij en veilig kunnen ontmoeten.

Waarom deelnemen?

• Je krijgt een beter overzicht van welke organisaties en initiatieven er zijn in Nederland op het gebied van Public Tech. Je hoort ook over zaken die nog in de pijplijn zitten.
• Je krijgt een beter idee welke thema’s belangrijker worden de komende jaren.
• Je kunt werken aan strategische afstemming met organisaties die vergelijkbare doelen nastreven (wie doet wat).
• Je kunt kansen zien om samen te werken aan projecten, om gezamenlijk projecten op te starten, om gezamenlijk op te trekken in communicatie, om gezamenlijk het overheidsbeleid te beïnvloeden, etc.

Doelgroep

Mensen die binnen (of van buiten) de overheid werken aan digitale autonomie en/of publieke technologie. Voel jij je aangesproken, dan ben je welkom! We zoeken in ieder geval samenwerking met organisaties op het gebied van Public Tech, overheden en wetenschappers. Je bent ook welkom als je de intentie hebt om na de bijeenkomst de ideeën en initiatieven verder te brengen.

Verwachting Het is een vrijdag, het eind januari, binnen is het lekker warm en we zijn op het Marineterrein. We eindigen met een borrel, en daarvoor is wat meer massa en samenwerking ontstaan in het streven naar meer digitale autonomie binnen de overheid.

Locatie De Garage van Innovatie gemeente Amsterdam. Dat is gebouw 027S op het Marineterrein, Kattenburgerstraat 5, 1018 JA Amsterdam.

🏠 18:00 - Arrival: Networking, Drinks & Snacks (30 min.) Grab yourself snacks & drinks and say hello to everybody else!

📅 18:30 - So you want to observe an Event Driven System? (45 min.) 🎙️Speaker: Roman Boiko, Enterprise Sales Engineer @ Datadog

Event-driven architectures offer powerful decoupling, but they often shatter traditional monitoring strategies. When a single business process jumps across multiple queues, buses, and microservices, tracing the line between cause and effect becomes a complex puzzle. This talk bridges that visibility gap by exploring practical observability strategies using OpenTelemetry. We will navigate the critical architectural decisions behind distributed tracing - specifically choosing between Span Linking and Parent-Child relationships - and master context propagation to ensure no transaction is lost in the noise. Join us to learn how to connect low-level technical data with high-level business metrics, turning asynchronous complexity into a clear, manageable system.

Roman Boiko is a Senior Enterprise Sales Engineer at Datadog, where he helps developers and architects build reliable, observable, and scalable systems. With a strong background in serverless and cloud-native architectures, he’s passionate about bridging the gap between engineering and operations to help teams move faster with confidence. Roman frequently speaks at tech events, sharing practical insights on observability, distributed systems, and modern application design. He enjoys exploring how developers can simplify complexity and deliver better software through data-driven decisions.

📅 19:15 - Datadog at Zendesk - a solid foundation for scalable, reliable and cost efficient systems (30 min.) 🎙️Speaker: Anatoly Mikhaylov, Principal Software Engineer & Datadog Ambassador @ Zendesk

Anatoly will share practical and valuable lessons what value Datadog brings and what role it plays at Zendesk. They customized and encorporated observability triad (APM, Logs and metrics) within a large volume of systems and applications. Zendesk made it work very well at scale and so that Datadog became a common language engineers and product teams can speak to one another. A single picture often helps to narrow down the issue, surface the problem, brings the solution and be confident remediation is applied successfully. Zendesk teams are fluent using complex Datadog tools and drive necessary changes.

Speakers

​​Colin Miller mostly grew up in Austin, Texas, where he developed an early interest in software and maps. After his freshman year of college, he launched his first startup, Redistricter, which took off far faster than expected. He left school and moved to New York to pursue it full-time. ​A year later, he created Subway Builder, a hyper-realistic game that lets players design subway systems from scratch while navigating real-world constraints and costs. The game simulates millions of commuters using Census and Redistricter data, powered by the same pathfinding algorithms people rely on to get to work. Your job is to design a route network that gets the most people to their destination as fast as possible.

Join R-Ladies Ottawa for a casual evening of programming on Tuesday, January 27th. We'll be participating in TidyTuesday, a weekly data visualization challenge organized by the R for Data Science community.

What is TidyTuesday?

Every week, a new dataset is posted online on the TidyTuesday GitHub repo, and folks from around the world create data visualizations using the dataset. It's an opportunity to put your programming skills into practice using real-world data in a way that's fun! It's also a great way for everyone to learn from each other, by sharing their visualizations and code.

What will the dataset be?

Even we don't know that (yet)! We'll have to wait until the day before the event to know what data we'll be working with. If you're interested in seeing some past datasets, take a look at the examples below, or visit the TidyTuesday GitHub repo to see all of the datasets dating back to 2018.

Examples from past TidyTuesdays:

• Donuts, Data, and D'oh - A Deep Dive into The Simpsons
• Pokemon
• What have we been watching on Netflix?

Do I have to use R?

No! You can use any programming language or visualization software that you want. In fact, Python users from around the globe participate in "TyDyTuesday" on a weekly basis.

Who is this event for?

No previous programming experience is required to participate, and we'll have experienced programmers in the room who can help you get started (or unstuck), if needed.

...But if you want to get the most out of the event, a good way to prepare is to watch the recording of the introduction to data visualization workshop we hosted back in 2024. :)

What should I bring?

• Please bring a laptop so you can code along. We recommend that you have RStudio or another IDE (such as VS Code or Positron) installed ahead of time, but we can help you get one installed if needed!
• Come ready to learn, share, and contribute to a safe and welcoming community!

How will this event work?

• First few minutes of the event: Introductions, and taking a look at the dataset together as a group.
• Time to create a data visualization using the language or software of your choice, either on your own or with a (new) friend! Grab a free snack while you're at it :)
• Last \~30 minutes of the event: Show and tell session for anyone who would like to share their creation with the group.

What else do I need to know?

This event (like all R-Ladies events) is totally FREE to attend.

The event will take place at Bayview Yards, which is located just a few steps away from the Bayview O-Train station. There is also a free parking lot available for those who are driving. You can find us in the "Training Room", which is on the second floor of the Bayview Yards building.

This is an in-person event with limited space! Please only RSVP if you are able to attend in-person!

***Please note that the mission of R-Ladies is to increase gender diversity in the R community. This event is intended to provide a safe space for women and gender minorities. We ask for male allies to be invited by and accompanied by a woman or gender minority.***

We’re grateful to be part of the Bayview Meetups initiative and extend our thanks to Bayview Yards for generously providing the venue space.

Encore un event Boost Your Skills et cette fois pour parler Machine Learning : Comment optimiser les modèles de Machine Learning ?

L’optimisation des modèles de Machine Learning est un des principaux enjeux pour un Data Scientist.

L'objectif est surtout d'obtenir de meilleures performances et d'augmenter la précision du modèle, en particulier dans des secteurs où les erreurs peuvent avoir un réel impact.

On parle notamment d'optimisation des hyper-paramètres.

Il existe plusieurs méthodes d'optimisation. Nous avons des techniques “classiques” avec les méthodes par grilles, faciles à mettre en place, mais qui présentent leurs limites.

Ensuite nous avons les méthodes bayésiennes, où l'on capitalise sur les expérimentations précédentes pour s'orienter vers les bonnes valeurs.

Contrairement aux précédentes méthodes qui évaluent chaque expérimentation de manière indépendante, l'optimisation bayésienne est vu comme LA méthode de choix pour les modèles longs à entraîner.

Il s’agit d’un sujet clé pour gagner en efficacité.

Voici le plan du Workshop :

✔️ Présentation des méthodes de recherche par grille

✔️ Présentation des méthodes bayésiennes

✔️ Lien avec l’AutoML

✔️ Cas d'application

Etc … 🖥

L’optimisation en Machine Learning n’aura plus aucun secret pour toi suite à cet event.
