In this talk we will go into the 4 fundamental aspects within software engineering; problem solving, managing state, managing errors and managing side effects. There will be almost no functional programming terminology used but instead focus on recognizable examples (in Java) and look at them from a different angle that you might have never concidered. So if you want to improve your problem solving skills and get better in abstract thinking without having to learn what a monad is, this is the talk for you. false https://pretalx.t-dose.org/2024/talk/DCZYKR/ https://pretalx.t-dose.org/2024/talk/DCZYKR/feedback/ Kleine Spoel (0.31) Talk 2024-06-01T11:00:00+02:00 11:00 00:50 None 2024-7-sphinx-a-very-different-kind-of-password-manager Presentation en SPHINX (yeah yet another project with this name) is a very simple cryptographic protocol with some very powerful security guarantees that go way beyond traditional online password managers. Even if the "password database" of the server is ever compromised, the only way to bruteforce it is using an online attack - every guess must be tested against a server with the account to be guessed. This also applies to anyone hosting your "password database", even the NSA. With traditional password managers if the db is leaked offline bruteforce attacks are possible and thus much more economic. Above we referred to "password database" in quotes, because there is none! Actually with the latest version this none is also distributed between multiple servers, in a threshold setting, like Shamir's secret sharing if you know what that means. if not, come to the talk or hit me up afterwards... I know, everyone who cares already uses a password manager, And those who don't, are actually not (yet) a target of this. It's an uphill battle, but it is totally worth it. If any of you is interested, I am looking for users (there is importers available from most popular "legacy" password managers) and more importantly i am looking for people hosting a public server. Furthermore, i am also happy if anyone starts doing clients for the Apple ecosystem, i guess i won't find much interest at a free software event, but it is necessary if we want to bring this to the masses... false https://pretalx.t-dose.org/2024/talk/DNHNFU/ https://pretalx.t-dose.org/2024/talk/DNHNFU/feedback/ Kleine Spoel (0.31) Talk 2024-06-01T12:00:00+02:00 12:00 00:50 None 2024-28-1-year-of-mikochi-the-remote-file-browser Presentation en Mikochi is a minimalist remote file browser, that provides a web interface to manage, download, and even stream files from a remote server.

Software developers are not field experts in copyright and licensing, and (rightfully) do not want to be. Fortunately, the REUSE Initiative by the Free Software Foundation Europe seeks to make copyright and licensing as easy as possible for developers. With three simple steps, it makes the process easy for humans and readable for machines, as well as comprehensive and unambiguous. To make adoption as easy as possible, REUSE comes with documentation and tooling, most importantly a linter that verifies that you have comprehensively licensed your code and provided all the necessary licence texts. This talk is an introduction for the uninitiated, giving an overview of the initiative and some guide lines on how to become compliant. false https://pretalx.t-dose.org/2024/talk/9JNRHC/ https://pretalx.t-dose.org/2024/talk/9JNRHC/feedback/ Kleine Spoel (0.31) Talk 2024-06-01T14:00:00+02:00 14:00 00:50 None 2024-18-api-and-microservices-in-brokerage-infrastructure-to-use-or-not-to-use- Presentation en The adoption of APIs and microservices has become a significant trend in financial services, especially within brokerage infrastructure. This talk explores the pros and cons of these modern architectures. Pavel Perfilov delves into the benefits of APIs, such as enabling new product development and boosting trading volumes, while also discussing the challenges, including IT security risks and the complexity of networking with microservices.

We fund projects that help fix the internet through open hardware, open software, open standards, open science and open data. It is the lead of the Next Generation Zero, a coalition op non-profit organisations running multiple grant programs funded by the European Commission. The NGI Zero programs do not only offer grants but also support services like security and accessibility audits which help improve the quality and maturity of free and open source projects. We will give a short 15 minute presentation and leave lots of room for questions. But most importantly, projects funded by NLnet may get their own hex sticker. So far more than 150 projects have been hexified (https://nlnet.nl/gallery/hex.html).

De Nederlandse Hacker Camp cultuur is diepgeworteld in het ethos van openheid, samenwerking en exploratie. Deze kampen worden doorgaans georganiseerd door vrijwilligers uit verschillende hacker- en maker gemeenschappen in Nederland en trekken deelnemers van over de hele wereld aan die geïnteresseerd zijn in technologie, hacken, DIY-cultuur en digitale vrijheid. Het meest recente Nederlandse Hacker Camp is "MCH2022" (May Contain Hackers), dat werd georganiseerd door de Nederlandse Stichting IFCAT* in een kleurrijke traditie van vierjaarlijkse hackerkampen. Het Nederlandse hackerkamp maakt deel uit van de grotere reeks internationale hackerkampen, waaronder het Chaos Communication Camp (Duitsland) en het Electromagnetic Field (VK). Deze kampen bieden vaak een gevarieerd scala aan activiteiten, waaronder workshops, lezingen, hackwedstrijden, kunstinstallaties en sociale bijeenkomsten. Deelnemers kunnen leren over onderwerpen zoals computerveiligheid, hardware hacking, cryptografie, privacy en vrije software. In de loop der jaren zijn Nederlandse Hacker Camps geëvolueerd en gegroeid in omvang en populariteit, waarbij ze niet alleen hackers en technologie enthousiastelingen aantrekken, maar ook kunstenaars, activisten, opvoeders en anderen die gepassioneerd zijn over het verkennen van de intersectie van technologie en samenleving. Al met al spelen Nederlandse Hacker Camps een belangrijke rol bij het bevorderen van een gevoel van community, het bevorderen van innovatie en creativiteit, en het pleiten voor digitale rechten en vrijheden. Ze bieden een unieke ruimte voor mensen om samen te komen, van elkaar te leren, en samen te werken aan projecten die de grenzen van technologie en verbeelding verleggen.

In 2017 werd het bij mij geconstateerd en de weg naar (bijna volledig) herstel was behoorlijk lang. Toch had ik het kunnen voorkomen, mits ik had geweten waar ik op moest letten. Een werknemer met een burn-out is gemiddeld 279 werkdagen ziek. Tijdens het herstel leerde ik veel over wat een burn-out is, hoe je het krijgt, wat je eraan kunt doen en hoe je het kunt voorkomen. Maar ook wat het verschil is met verspannen zijn. In mijn presentatie laat ik al deze genoemde punten aan bod komen, en ook waarom gemotiveerde mensen het kwetsbaarst zijn. Ik hoop dat mensen na deze presentatie bij zichzelf kunnen nagaan in hoeverre ze zelf in de gevarenzone zitten. Voor deze presentatie is geen technische- of andere voorkennis nodig.

Whereas most people nowadays do so for financial gain, 35 years ago the world looked different. The internet connected academia. The people hacking were students, almost the only people who had access. Not many system administrators were paying much attention to security and for hackers, breaking into sites such as that of NASA, were ways to gain a reputation.
