After a long pause we finally had our event in October. This time with two talks by Matti and Raido from GrabCAD and Konstantin from Malwarebytes.

Matti and Raido shared their experience of building a cross-platform desktop app with web development tools. With electron framework they managed to build and ship fully functioning 3D pringing preparation and management tool. This is a smart way to utilize existing web development experience to build native apps. This also allowed them to reuse certain components in both web and native apps. The video recording is available here.

Konstantin made an introduction to HTTP headers designed to improve security of a website. He started with an overview of the old school class of headers, then moved to the modern ones. Described how they work and what kind of attacks they protect from. Also told about some gotchas and how not to shoot oneself in the foot using them. Video is here.

You can find slides for both talks in our site archive, and photos are here.

Also, if 3D printing topic is interesting for you, make sure you don’t miss GrabCAD’s Print Workshop on Thursday, December 1st. Sign up here.

It’s been couple weeks since our last event, so here’s the follow-up:

Last devclub was hosted in Transferwise new office in Baltika district. It is located almost exactly where their previous office was, right the opposite building. Transferwise is really great host, made this event special and guests feel very welcome. We’d love to come again to them with Devclub the other time.

This time we had four speakers and three talks. First one was by Erko Risthein from Transferwise. The talk was more financial than technical. It was about currency rate change risk management and how to perform money transactions with different currencies and not loose money when currency exchange rate is changed. The idea is quite simple, yet really smart. Each time you sell some amount in one currency you buy equivalent value in other currency and vice versa. This ables you to lock the exchange rate between these two currencies at certain state that existed at the moment when transaction started. It is called currency hedging. Erko did great job explaining this concept in his talk, I’m really glad I had a chance to hear and see him. Now I have good understanding on the subject.

Second talk was also by Transferwise engineers Dmitry Zhukov and Maksims Juvcenko. Their talk was about how they built a fraud detection engine. It was a story about how the project evolved and how the guys helped it to get better. How to get started when everything needs to be fixed and everything is important. How to make decisions and prioritize in though circumstances.

Can’t really say much about the last talk as I did it myself. Probably it was epic 🙂 I was talking about AWS Lambda – what it is, how we use it for our needs in Folkefinans and how you might want to use it.

There was an office tour after the talks too, had to skip this one so can’t really say much about the office. From what I managed to see it looked really nice, definitely a place you want to be in.

Unfortunately there’s no pics from the event this time, but at least we managed to record the videos of the talks (here, here and here), so there’s a great way for you to follow-up if you missed it. This is pretty much about it. Thank you and see you at the next Devclub really soon!

Last tuesday we had one of the most crowded devclub so far. Awesome vibe, good emotions and great talks. On behalf of DevClub team I want to thank the speakers and the audience for making it happen. Special thanks goes to Pipedrive for being very welcoming host, we’d love to come to you with DevClub again one day.

We had two talks this time, they were very different and both were great.

First on the stage was Martin Tajur, the CTO of Pipedrive. His talk was about event-driven architecture and about RabbitMQ in particular. This quite hot topic among tech people for last several years already. The talk was an introduction to RabbitMQ, really high value for people who’d like to get started with event-driven architecture but lack the basic knowledge. The feedback was really good also, lots of interest and questions from the audience.

The second talk by Anton Keks, software developer at Codeborne was about encryption and digital signatures. Anton told a story about how easy and common it is in Estonia and how much effort it takes to implement digital signing in other countries on example of Russia. The talk was really live and interesting, included some historical background on topic and some interesting facts, such why two different private keys are used for authentication and digital signing given that the technology behind both actions is exactly the same. There was also live discussion with Anton after the talk.

After the talks Pipedrive organized a guided office tour, which was really nice of them. Photos and videos of both talks are available below.

Google photos, video of Martin’s talk and video of Anton’s talk.

See you in March on our next event hosted at Transferwise!

Our October event went really good, it was pleasure to see more people attending to Devclub this time. We had around 60 visitors, which is circa 20 more than we got last time in September. Whether it is because of summer is over and people are coming back from vacations or the agenda, the attendance dynamic is positive and I really like it.

This time we had two talks and three speakers. Taivo and Risto from Funderbeam told a story about how they aggregate and validate the data about companies and also about a ‘startup marketplace’ that they’re building at Funderbeam. The talk caused many questions in the audience, mostly about the fact that Funderbeam is going use Blockchain for the marketplace they’re building.

Asko Tiidumaa from Fortumo told a story about how they solved their scalability problems at Fortumo. The key solutions was to break hard-to-scale monolith app down to smaller services that are easier to scale and maintain. Another cool thing they did to increase performance is switched communication between their services to RabbitMQ. Microservices way to solving scalability problems is fairly common, and Fortumo example showed it is efficient too.

This is it for October event wrap-up, here you can get the photos, and videos are coming soon. Follow the announcements and make sure you don’t miss November event – same place, end of November. See you there.

Seekordne Devclub oli järjekordselt eriline – nii nagu Alek sisse juhatades ütles.

J.B. Rainsberger alustas ja rääkis meile, kuidas Test Driven Development-i teistele “müüa”. Muu hulgas soovitas ta mitut raamatut mis ei pruugi esmapilgul progejate lauale sattuda. Kõige eredamalt jäi meelde “The New Strategic Selling”, mis on abiks suvalise idee maha müümisel. TDD jutu vahele rääkis ta ka väga lahedalt oma imetlusväärsest kaalulangetamisest – ta on lühikese ajaga saanud lahti umbes poolest oma kehakaalust. Kõigile TDD-s kahtlejatele olgu heaks näiteks J.B. enda testide avastamise lugu – kuidas ta ise tundis vajadust asju paremini ja kvaliteetsemalt teha. Ta sai aega kolm nädalat ja suutis oluliselt pikema aja jooksul kirjutatud bugise funktsionaalsuse ümber kirjutada bugivabaks hea disainiga lahenduseks.

Teine esineja oli Andres Jaan Tack Skypest. Tema rääkis mitte-relatsioonilistest suurtest andmebaasidest – mis on neis head ja mida halba. Oli tõeliselt mõnus kuulata sõltumatut vaadet sellesse maailma. Tavaliselt räägivad sellest mehed, kes seda pikka aega kasutanud ja usuvad, et kõik teised lahendused on halvad võrreldes sellega. Tegelik elu on veidi erinev ja ka suurtes firmades pole selget nägemust, mis on parim lahendus ning kas ACID on ikka hea või halb.
