We use this, great to see it officially announced! This helps offer apps to potential/current/former employees without competing with yourself in App Store search results. The only way to load the App Store app page is via the direct apps.apple.com link. Past that, the app is treated like any other.

You still go through the regular app review process, but honestly I think employees appreciate that and trust the app more seeing it come from the App Store rather than from some enterprise MDM app that prompts for a whole lot of device access/trust.

What a great case study. Successfully shifting 80% of mobile traffic to QUIC for a 50% reduction in latency is amazing. QUIC and the ongoing work with multipath TCP/QUIC will be huge QoL improvements for mobile networking.

The other awesome thing about QUIC is that it encrypts almost everything including header information, making middlebox traffic shaping worthless and demoting middleboxes in general.

It also makes hardware offloads like TSO and LRO impossible, and increases cost-per-byte served by a factor of 4 or more. So if you have infinite CPU to throw at QUIC and/or low bandwidth or connection targets, its great. If you are concerned at all about server-side efficiency, its terrible.

FWIW, I work on the Netflix CDN, and specialize in server-side efficiency; we have had 100G flash CDN nodes for years serving at 90G+ in production. None of that would be possible with QUIC as it stands. I suspect our max B/W on these machines would drop from ~95Gb/s to 20Gb/s or less if we were to switch to QUIC.

I hear you and those are valid points.

Don't blame QUIC. Blame ISPs and middlebox makers for abusing their (literal network-wise) position and breaking the end-to-end principle. History has shown that we just have to encrypt everything and quite literally cut out the middleman/box.

Does the protocol actually make it impossible, or is it just not implemented by current OS/hardware?

Definitely just that the HW hasn't caught up.

This article is about mobile apps

Native mobile apps are great only because it's so much more difficult to pile on shit (newsletter signups, ads, GDPR popovers, etc)

Data Skeptic is great! Alternates between <10 min shorts on a specific concept as well as longer interview shows.

This was very informative, thank you!

One big challenge was it didn't account for gated hotspots (hotels, Starbucks, etc) where you need to authenticate to reach the Internet.

I didn't find it online either, but did just pick up the book. This is ToC of pre-release #2 (~500 pages): http://i.imgur.com/ssYr5ki.png

C# & Javascript/Node. You can find the sample code from projects in the book here: https://github.com/imposters-handbook/sample-code/

For C# I recently found this course, looks pretty good: http://www.brpreiss.com/books/opus6/html/page10.html

I just picked it up. Looking great at the moment. There are diagrams and illustrations throughout, and the ToC is a solid list of things I have had to figure out on the way & things I know of but don't yet understand.

This'll be worth the $30 to me.

Thank you for bringing attention to the remark as you did, and for sharing your own experience.

Wow, in concept and execution the artwork is really well done! Thanks for creating this!

Glad you like it! It was a lot of work ... especially getting it ready in time for SysAdmin day -- but it was also a ton of fun!

I hope you enjoy coloring it :)
