NXTA - NexTech Africa Conference - Day 1 perspectives

imageI'm in Nairobi, Kenya this week attending a fantastic event called NexTech Africa. It is a free event that showcases the best of what Africa's Startup community has to offer. This event is mostly focused on East Africa's tech community but it included delegates from all over the continent. I'm told over 1000 people are here.

My wife is Zimbabwean and we have family all over in places like South Africa, Tanzania, and Zimbabwe, and friends in a dozen other countries. I personally feel that access to technology and technical education is a fantastic way to help Africa's burgeoning middle class.

However, this trip was for listening. It's silly for me (or anyone who isn't living on the continent) to fly in and "drop the knowledge" and fly out. In fact, it's condescending. So I'm spending this week visiting startups, talking to engineers, university students, and tech entrepreneurs.

I spoke at length with the engineers at BRCK, a Kenya-based startup that has a "brick" that's a portable router, NAS, Compute Module, Captive Portal, and so much more. They can drop one of these a little outside of town and give wi-fi to an entire area. Even better, there could be hyper-local content on the devices. Folks with 30+Mbps Internet may be spoiled with HD content, but why not have a smart router download TV shows and Movies that can be served (much like movies stored on an airplane's hard drive that you can watch via wi-fi while you fly) to everyone in the local area. The possibilities are endless and they're doing all the work from hardware to firmware to software in-country with local talent.

I also visited iHub's Technology Innovation Community and saw where they teach classes to local students, have maker- and hacker-spaces, support a UXLab and host local tech meetups. I'll be hopefully communicating more and more with the new friends I've met and perhaps bring a few of them to the podcast so you can hear their stories yourself.

These are uniquely African solutions to problems that Africans have identified they want to solve. I am learning a ton and have been thrilled to be involved. Since I focus on Open Source .NET and .NET Core, I think there's an opportunity for C# that could enable new mobile apps via Xamarin with backends written in ASP.NET Core and running on whatever operating system makes one happy.

VIDEO: How to get started with technical public speaking!

January 26, '17 Comments [12] Posted in Musings

On .NET is a weekly chat with team members from the .NET team at Microsoft. This week we put together something a little different, and honestly, I think it not only went really well, but I think it's an hour that provides a lot of value that goes well beyond .NET or any technology.

image

We put together a panel of folks at different points in their technical careers. Some just starting to speak publicly and some who've been doing it for 20+ years. Some introverts, some extroverts. Some with speaking or theater experience, others with none. And we talked!

We chatted about how to get started, where you can learn to speak on technical topics, how to form a story arc, how to best utilize your gifts, when to be critical and when to breathe.

It was great fun and included myself, Kendra Havens, Maria Naggaga Nakanwagi, Kasey Uhlenhuth, and Donovan Brown. You can view or download it here on Channel 9, or you can watch it on YouTube embedded below.

Let us know if this kind of content is useful, and if you want to see more in the future.

Solved and Fixed: StreetPass stopped working on Nintendo 3DS XL

Nice to meet you! says my MiiYes, this is kind of a silly blog post but it's been bugging me for months so I wanted to get it out there in case it helps someone who is googling for the answer!

I have a little Nintendo 3DS XL (the "new" one) that I bought for long trips. It's a great little device with a large library of games, plus it plays SNES classics like Super Metroid. All in all, I'm thrilled with the purchase.

It has wifi, and both Netflix and Hulu in a pinch for the kids, but it also has some really cool social features using a proprietary wifi connection called "StreetPass." The nutshell is that if you pass by someone (within 30-40 feet in my experience) their "Mii" avatar will jump into your game console and bring with it data from other games.

There's simple stuff like Puzzles, there's mini games like Find Mii, and StreetPass enhances more complex games like Mario World or Resident Evil: Revelations by adding in whole new components. In Resident Evil you'll get communications and weapons drops from your colleagues who are apparently fighting zombies at the same time as you. In Shovel Knight you can race the "ghost" of another player. It's safe and anonymous.

If you travel it's even cooler as you'll StreetPass people in airports and collect their countries or states of origin. I carry my 3DS to conventions and all over the world. It's a hoot.

BUT. A few months back it stopped StreetPassing. Nothing happened, ever. I made sure everything was updated, turned it on and off, but nada.

Recently I fixed it and I'm sure it will fix StreetPass for you also.

  • Go into Mii Maker and design a secondary Mii. Doesn't matter what it looks like. I did it quickly.
  • Switch to that secondary Mii. You won't lose anything.
  • Exit Mii Maker, then go back in and switch back to your original Mii.
    • I surmise that this clears things out and re-writes some settings for you.
    • I also changed my Mii's hat and outfit just to make sure it was re-written completely.
  • Head over to Mii Plaza and you should be all set.

My system started StreetPassing within a few hours.

I hope this helps someone because as a traveller who really digs StreetPass, having it not work was really harshing my mellow. By the way, I REALLY love this "DreamGear" rubber case I got for my 3DS. It changes the shape of it, makes it larger, almost like an Xbox controller. That's an Amazon link that you can use that will help me get more 3DS games. ;)

Working with Multiple .NET Core SDKs - both project.json and msbuild/csproj

January 21, '17 Comments [10] Posted in

As .NET Core and ASP.NET Core make the transition from project.json style project files to MSBuild (csproj) style files, I'm starting to get myself up to speed on what's needed, what's changing, and why/if it's a good thing. Documentation is still getting updated but there's a great blog post from Nate McMaster who works on the team.

As I touched on in a previous post, you can continue working on project.json based projects while experimenting with the newer stuff. Here I have a global.json with the version pinned to an earlier SDK. Then I move to another folder and the .NET CLI gives me another version. Projects can remember and pin their SDK versions.

Global.json is useful

This is assuming that you do have multiple versions (and the ones you want) installed:

Here I have 4 SDKs installed and I can see them in my installation folder

To be clearer, I'll run "dotnet new" in one folder and again run "dotnet new" in another. Note that one has global.json pinned older "LTS" (Long Term Support) SDK with project.json and one will use the later "Current" (bleeding-edge) stuff.

See how that works?

C:\Users\scott\Desktop\csprojstuff> dotnet new
Created new C# project in C:\Users\scott\Desktop\csprojstuff.

C:\Users\scott\Desktop\csprojstuff> dir
Volume in drive C is Windows
Volume Serial Number is 00C1-AED2

Directory of C:\Users\scott\Desktop\csprojstuff

2 Dir(s) 149,845,356,544 bytes free

C:\Users\scott\Desktop\csprojstuff> cd ..\projjsonstuff

C:\Users\scott\Desktop\projjsonstuff> dotnet new
Created new C# project in C:\Users\scott\Desktop\projjsonstuff.

3 File(s) 676 bytes
2 Dir(s) 149,844,484,096 bytes free

Now I can also "migrate" that project.json forward with "dotnet migrate." That's a NEW command so look what happens if I just run it locally there without changing the global.json pinned SDK version? Doesn't work. For this example I'll delete global.json and run it again.

C:\Users\scott\Desktop\projjsonstuff> dotnet migrate
No executable found matching command "dotnet-migrate"

C:\Users\scott\Desktop\projjsonstuff> del global.json

C:\Users\scott\Desktop\projjsonstuff> dotnet migrate
Project projjsonstuff migration succeeded (C:\Users\scott\Desktop\projjsonstuff)

Again, go check out Nate's excellent blog on the topic. He also covers briefly how you can publish "Standalone" or "Self-Contained" Deployments, and points out that in MSBuild world, all projects are portable until you decide to target a runtime:

dotnet publish --framework netcoreapp1.0 /p:RuntimeIdentifier=osx.10.11-x64

More on this as it comes!

Three FREE Training Courses on ASP.NET Core from Microsoft Virtual Academy

January 17, '17 Comments [18] Posted in ASP.NET
Sponsored By

This time last year we did a Microsoft Virtual Academy class on what was then called "ASP.NET 5." It made sense to call it 5 since 5 > 4.6, right? But since then ASP.NET 5 has become .NET Core 1.0 and ASP.NET Core 1.0. It's 1.0 because it's smaller, newer, and different. As the .NET "full" framework marches on, on Windows, .NET Core is cross-platform and for the cloud.

Command line concepts like dnx, dnu, and dnvm have been unified into a single "dotnet" driver. You can download .NET Core at http://dot.net and along with http://code.visualstudio.com you can get a web site up and running in 10 minutes on Windows, Mac, or many flavors of Linux.

So, we've decided to update and refresh our Microsoft Virtual Academy. In fact, we've done three days of training. Introduction, Intermediate, and Cross-Platform and all three days are now available! We just released training for ASP.NET Core 1.0 Cross-Platform that shows Mac, Ubuntu, and Docker!

Head over to Microsoft Virtual Academy and watch our new, free "Introduction to ASP.NET Core 1.0." It's a great relaxed pace if you've been out of the game for a bit, or you're a seasoned .NET "Full" developer who has avoided learning .NET Core thus far. If you don't know the C# language yet, check out our online C# tutorial first, then watch the video.

Introduction to ASP.NET Core 1.0

Join experts Scott Hanselman and Maria Naggaga, and find out how to build .NET Core applications on any operating system. Bring your web development expertise and roll up your sleeves, for this first in a three-part series.

Intermediate ASP.NET Core 1.0

Want a deeper dive into ASP.NET Core 1.0? Build on what you learned in Introduction to ASP.NET Core 1.0, and explore this new technology even further, as Scott Hanselman, Jeff Fritz, and Rowan Miller offer an in-depth, intermediate-level look at ASP.NET Core 1.0.

Intermediate ASP.NET Core 1.0

ASP.NET Core 1.0 Cross-Platform

Ready to build and deploy ASP.NET Core 1.0 apps? Join experts Scott Hanselman, Maria Naggaga, and Glenn Condron, and see how to do just that using Mac and Linux. Revisit content from the Introduction to ASP.NET Core 1.0 course, but using a Mac and Linux.

Do us a favor when you watch these, rate them (5 stars!) and SHARE them on your social networks.

NOTE: There's a LOT of quality free courseware for learning .NET Core and ASP.NET Core. We've put the best at http://asp.net/free-courses and I encourage you to check them out!

Hope you have as much fun with these courses as we had creating them!
