Announcing Envoy Mobile. This is a fascinating development: Lyft’s Envoy proxy / service mesh has been widely adopted across the industry as a server-side component for adding smart routing and observability to the network calls made between services in microservice architectures. “The reality is that three 9s at the server-side edge is meaningless if the user of a mobile application is only able to complete the desired product flows a fraction of the time”—so Lyft are building a C++ embedded library companion to Envoy which is designed to be shipped as part of iOS and Android client applications. “Envoy Mobile in conjunction with Envoy in the data center will provide the ability to reason about the entire distributed system network, not just the server-side portion.” Their decision to release an early working prototype and then conduct ongoing development entirely in the open is interesting too. # 18th June 2019, 6:42 pm

When should you be using Web Workers? 85% of worldwide mobile devices are massively less performant than high end iPhones. Surma argues that we should be making aggressive use of Web Workers to keep as much of our JavaScript as possible off the main UI thread, to avoid freezing up the entire interface. # 15th June 2019, 4:31 am

Sunsetting React Native at Airbnb. “Due to a variety of technical and organizational issues, we will be sunsetting React Native and putting all of our efforts into making native amazing.” Fascinating write-up from Airbnb (part of a series) based on two years of working with React Native. It’s worth reading this in full: 63% of their engineers they surveyed would have chosen React Native again given the chance and 74% would consider it for a new project—but the larger technical and organizational challenges (in particular the fact that React Native remains a polarizing choice in the mobile world, making it harder to hire great native engineers) mean that Airbnb are migrating back to pure-native for their iOS and Android apps. # 19th June 2018, 9:03 pm

Are there any good bootcamps, such as Code Fellows, DevBootCamp for mobile (iOS/Android)?

Big Nerd Ranch have been offering iOS and Android for several years now. A friend of mine went in the iOS course a while ago and spoke highly of it—he has since released an app to the App Store.

Is it possible for anybody to be expert in all areas of software development, that includes database, backend, web frontend, mobile apps, and graphic design?

It isn’t possible for someone to be expert in “all” aspects of software development—that would include everything from writing safety critical control systems for nuclear power plants in Fortran to high frequency trading algorithms on Wall Street. The world of software development is simply too big for that now.

Mobile World Congress: Is it worth going?

It depends on what you want to get out of it. I haven’t been myself, but from what I’ve heard MWC is the Mobile world’s equivalent of something like SXSW—huge (49,000+ people), sprawling, bewildering and full of everyone you could possibly want to meet from the mobile world.

Unlocking the Huawei E5830 aka 3 Mifi. 3 will post you an unlocked replacement for your MiFi for £15, if you can figure out how to ask them to do it. Reports on the internet are that it can take several weeks and they sometimes forget to unlock the one you send them, so I went the self-unlocking route. These instructions (involving Windows running in VMWare Fusion, Firmware updates, PayPal, some very dodgy looking software and a PDF file half-written in Japan) ended up working a treat. # 17th June 2010, 10:57 pm

Flash was created during the PC era – for PCs and mice. Flash is a successful business for Adobe, and we can understand why they want to push it beyond PCs. But the mobile era is about low power devices, touch interfaces and open web standards – all areas where Flash falls short.

Notes on designing the Guardian iPhone app. By John-Henry Barac, the principal designer of he iPhone application who also previously worked on the Guardian’s print transition to the Berliner format. # 20th December 2009, 12:55 pm

We’re at a critical juncture in the evolution of software. The web is still here and it is still strong. Anyone can still put any information or applications on a web server without asking for permission, and anyone in the world can still access it just by typing a URL. I don’t think I appreciated how important that is until recently. Nobody designs new systems like that anymore, or at least few of them succeed. What an incredible stroke of luck the web was, and what a shame it would be to let that freedom slip away.

Correct way to handle mobile browsers. If your site has an equivalent “mobile” version running on a different subdomain, how and when should you redirect mobile users to it and how should you let them opt in or opt out? # 10th November 2009, 8:57 am

WebKit, Mobile, and Progress. Alex Russell responds to PPK’s analysis of the many different WebKit variants in today’s mobile phones, pointing out that the replacement cycle and increasing quality of WebKit in more recent phones means the situation still looks pretty good. # 10th October 2009, 12:28 am

Kapow SMS Gateway. Looks like a solid provider for sending and receiving SMS messages, with APIs provided over both e-mail and HTTP in both directions. # 8th December 2008, 5:05 pm

I can’t question that [the App Store] is probably the best mobile application distribution method yet created, but every time I use it, a little piece of my soul dies.

minidetector. Neat piece of Django middleware that adds a “mobile = True” attribute to the request object if the request’s user-agent matches a list of strings of known low-power browsers in mobiles, PDAs or game consoles. # 15th August 2008, 8:21 am

DeWitt Clinton: T-Mobile and Twitter. “If you think the rest of Internet needs net neutrality laws, that’s nothing compared with the backward-facing worldview of the established mobile carriers.” # 15th December 2007, 12:26 pm

CSS3 and the death of Handheld Stylesheets. I hadn’t looked at CSS 3 media queries before (which let you apply different styles based on media features such as screen width, height and colour availability)—they seem like a much smarter solution that handheld stylesheets and also appear to be preferred by device vendors. # 16th November 2007, 9:53 am
