QCon Shanghai

QCon

Last month I had a pleasure to visit China and attend QCon conference in Shanghai.

I gave a talk about building large scale web apps with TypeScript where I updated my talk from last year to TypeScript 2.0, I showed TypeScript boilerplate project created by Remo Jansen, and using TypeScript with Aurelia Framework.

I had a great turnout. Room overflow with over 150 people. I also got a great feedback. People could vote green(awesome), yellow(ok), red(bad), and I received 128 green, only 10 yellow and 1 red, which gives over 92% extremely satisfied attendees.

QCon has the best of the best from the industry. In Shanghai I met Jaime Levy (famous UX strategist from LA), Kinshuk Mishra (Director of Engineering at Spotify), Pete Soderling (successful entrepreneur from New York and Silicon Valley, founder of Hakka Labs & DataEngConf), Sid Anand (former Cloud Data Architect at Netflix who implemented Netflix migration to the cloud that Adrian Cockcroft later on told the World about, former Tech Lead at LinkedIn where he implemented typeahead search, currently Data Architect at Agari – company that provides fraud detection services), Wesley Reisz (Solutions Architect at HP and University Professor), and Igor Marvić (Software Engineer at Spotify).

China is very interesting place for developers, especially because of its scale. They have over 700 million Internet users! One developer from alibaba.com – largest online store in China – told me that during Singles’ Day (Guanggun Jie), which is equivalent of Black Friday in USA, they had over 400 million customers online at the same time. This is more than entire population of the United States (~325 million). They also sold more than $1 billion in merchandise in first 8 minutes! This is SCALE!

While I was in China I was using WeChat (their Facebook equivalent). People don’t use Facebook and twitter, as they are blocked by China Firewall. You can workaround it using VPN, but sometimes it works very slow, or not at all. Thus, it is much easier to just use WeChat. When I am in USA I use Facebook, messenger and twitter everyday. However, I noticed that on my iPhone 5S, WeChat works much better than all mentioned apps. It doesn’t crash, it’s fast, and it has many cool features. Want to add somebody to friends? Just scan they QRCode. You can also shake your phone, and WeChat will try to find closest person who is also shaking their phone, and show on your phone their profile, and on their phone your profile.

Besides the conference, which was very well organized, I was very impressed by how modern the city of Shanghai is. The skyline looks almost like New York City! Shanghai Tower (2,073 ft / 632 m) is the second tallest building in the WorldShanghai World Financial Center (1,614 ft / 492 m) is number 9 on the same list, which contains only 1 American building – One World Trade Center (number 6 – 1,776 ft / 541 m).

It was a great journey, and all Chinese people were very nice for me. I look forward to come back to China in near future!


The taste of Netherlands: Tech Days NL in Amsterdam

TechDaysNL 2016

Earlier this month I had a pleasure to attend Tech Days NL conference in Amsterdam. It was very well organized conference.

I had opportunity to meet with many passionate developers. I met Bart de Smet. He is a C# Ninja who works for Microsoft at Bing Team, but he also C# compiler contributor. If you are C# passionate, like I am, I really recommend you to check out his talks. I also met Gil Cleeren (author of a few awesome Pluralsight courses about Xamarin, and organizer of Techorama conference), Roy Corneliasen (Xamarin MVP who is building mobile apps while working for Xpirit), and Mike Martin (Azure MVP). Check out their sessions as well! I’m looking forward to meet them again at MVP summit in Redmond this November!

Third time this year I spoke about the Azure Portal Architecture. I had to shorten my VSLive session from 1:15h to 45 mins. So if the VSLive session was too long, and too much of commitment for you, check out my Tech Days session 😉 I gave a high-level overview of our architecture, technologies we are using, our deployment approach, and lessons learned over last 2 years: performance tips & tricks, how to avoid regressions, and how to handle them when they happen.


Azure Portal – the largest Single Page App in the World

Azure Portal - dashboard

Last week I had a pleasure to attend and present the Azure Portal insights at the Visual Studio Live conference in Redmond.

Throughout the conference, 5 sessions were being presented simultaneously, and 1 session was being streamed live. My session was chosen to be streamed live, and is now available on channel9:


I updated this session since the last time when I presented it at NDC London. I restructured it, added more demos, and new section with performance tips&tricks that you can apply in your project. I encourage you to check it out!

I received a lot of great feedback after my session:

Now, I am waiting for YOUR feedback. Leave it in comments or tweet me at @JakubJedryszek. What did you like, what did you not like, what would you like to see that I haven’t show?

You can also check out other recorded sessions from VSLive at channel9.

I really enjoyed this conference. I had opportunity to meet many interesting people with passion in Software Development. From marketing people, through Software Developers, to CEOs and CTOs.

Interesting fact I learned from two gentlemen working as Software Engineers at Panama Canal: it cost hundreds of thousands of dollars to cross the Panama Canal once!

Open Source at Microsoft and Beyond

Open Source North

Last month I had a pleasure to attend Open Source North conference in Minneapolis, MN. It was a great event with over 500 attendees and speakers from all over across the United States. I had a pleasure to meet a lot of great people, and attend a few interesting talks. I also gave a talk “Open Source and Microsoft and Beyond” where I presented a bunch of Microsoft Open Source projects (ASP.NET Core, TypeScript, Xamarin, F#), gave an insight into Azure Cloud, and showed a few non-Microsoft OSS projects created or having contributions from Microsoft employees (lodash, xUnit, Moment.js, voiceCmdr, and more).

Thunder Plains 2015

Thunder Plains 2015

Last year I had a pleasure to attend and speak at awesome Thunder Plains conference in Oklahoma City.

I presented Aurelia Framework:

slides

I really liked this conference. Especially, because instead of having more talks that I could count, there was only 15 sessions (selected out of over 300) divided into 3 tracks. Moreover, all speakers were passionate developers, and you could feel this during their presentations.

I had a pleasure to met John-David Dalton – creator of lodash, who use to work at Microsoft for Chakra team, and now is working for Microsoft Edge team. I really enjoyed his talk on JavaScript performance. I also met Kyle Simpson – the author of You Don’t Know JS book series and awesome Pluralsight course: Advanced JavaScript. He presented inspiring keynote on choosing simplicity over easiness.

I also attended very good session – Maybe We Should Slow Down by Blaine Bublitz (author of over 400 npm packages). Blaine was convincing developers to think twice before contributing code, and publish only features they have high confidence about.

The coolest talk of the conference was JS in Near Space by Pawel Szymczykowski. I really recommend you to check it out. Pawel, together with his friends built a small space ship, powered by Arduinos and Raspberry Pis, and they are sending them into “Near Space”, up to ~100 000 ft altitude (Boeing 737 flies at <40 000 ft).

Actually, I have seen all talks (in person, or on youtube), and all of them were well prepared. There was no single talk about which I could tell that speaker was not good, or not prepared. You can check them out here:

Thunder Plains is community event organized by 3 passionates – Vance Lucas, Jesse Harlin and Amanda Harlin – who did a really good job in taking care of everything. Congrats!
