Azure Mobile App on Azure Friday

Last month I had a pleasure to talk about Azure App with Scott Hanselman on his show Azure Friday.

In this talk I presented Azure App architecture, our CI/CD infrastructure and how we took advantage of various benefits we get thanks to building app with Xamarin. Check it out!

If you want to learn more details about how we built the Azure App, check out my blog post Under the hood of the Azure Mobile App.

My talk was pretty technical. Deep into the meat. However, the same week, Michael Flanakin gave high-level overview of Azure App and our future plans:

Have you tried Azure App yet?

It is available on iOS and Android.

We would love to hear your feedback through our User Voice!


Quick intro to web development with TypeScript, webpack and Aurelia

TypeScript at SeattleJS

Earlier this month I spoke at SeattleJS meetup. I love this meetup! People attending it are awesome! Thank you Jeremy Foster for inviting me to speak! If you are living in Seattle area you should definitely check it out!

I gave fast-paced 30 mins overview of TypeScript. I showed a sample app that is taking advantage of webpack for continuous compilation, bundling and minification. I also did quick demo of Aurelia Framework <3

After presentation I got a lot of questions about migrating from JavaScript to TypeScript, and about specifics of building large web apps.

TypeScript team and Anders Hejlsberg shared with me a few interesting reads about migrating to TypeScript:

I also found out that Visual Studio Code was initially written in TypeScript, and before v1 release they switched to TypeScript.

Do you have questions or thoughts about migrating from JavaScript to TypeScript? Join discussion on twitter.

To learn more about specifics of building large web apps, check out my talk from Ignite Australia I gave earlier this year:

At the same conference, I gave a longer version of the talk I did at the meetup. So if you want to dive in deeper, the video is here.

It is also worth to mention that TypeScript is getting more, and more traction every day. If you are web developer you should seriously consider using it over pure JavaScript, or transpiled JavaScript vNext.

TypeScript = JavaScript vNext + types

Every valid JavaScript code is valid TypeScript code. Thus, by choosing TypeScript you have flexibility to use JavaScript, and opportunity to add type checks to some critical components of your project.

Once more, thanks SeattleJS for organizing awesome meetup and inviting me to speak! Great meetup, great people, keep up good work!


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.

QCon

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

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!
