One simple tweet made me feel terrible. One simple tweet made me doubt myself. One simple tweet – hopefully not meant to be mean – had a devastating effect on me. Here's how and why, and a reminder that you should not be the person that with one simple tweet causes anguish like that.

I believe that Yehuda would have expressed his response with more nuance and less stark brutality if he hadn't been limited to 140 characters. Twitter leaves no room for subtlety; it's not very well suited as a discussion platform :/

But I concur that those types of responses to your work can really throw you for a bit of self doubt.

Start of my insane May speaking tour and lots of Build videos to watch

I am currently in the Heathrow airport lounge on the first leg of my May presenting tour. Here is what lies ahead for me (with various interchanges in other countries in between to get from one to the other):

* 02-07/05/2015 - Mountain View, California for Spartan Summit (Microsoft Edge now)
* 09/05/2015 - Tirana, Albania for Oscal (opening keynote)
* 11/05/2015 - Düsseldorf, Germany for Beyond Tellerand
* 13-14/05/2015 - Verona, Italy - JSDay (opening keynote)
* 15/05/2015 - Thessaloniki, Greece - DevIt (opening keynote)
* 18/05/2015 - Amsterdam, The Netherlands - PhoneGap Day (MC)
* 27/05/2015 - Copenhagen, Denmark - At The Frontend
* 29/05/2015 - Prague, Czech Republic - J and Beyond

I will very likely be too busy to answer a lot of requests this month, and if you meet me, I might be disheveled and unkempt - I never have more than a day in a hotel. The good nes is that I have written 3 of these talks so far.

To while away the time on planes with my laptop being flat, I just downloaded lots of videos from build to watch, so I am up to speed with that. Here's my list, in case you want to do the same:

Thank you to all the people covering events and talks on Twitter. It helps me a lot in my job!
A few weeks ago, I wrote the That One Tweet post explaining how one tweet managed to puncture my balloon of happy and question if my work is appreciated. All of this is caused the gremlin of self-doubt living in all of us and it was mostly a reminder to tell it to mind its own business.

UA Sniffing issue: Outdated Mod Pagespeed sending WebP images to Microsoft Edge http://christianheilmann.com/2015/06/08/ua-sniffing-issue-outdated-mod-pagespeed-sending-webp-images-to-microsoft-edge/
MOD Pagespeed by Google is a great way to add clever performance enhancements to your site without having to do a lot by hand. Not surprisingly, a lot of people used it when it came out. Sadly enough, people then don't upgrade it when Google does which means there are a lot of sub-optimal ...

+Christian Heilmann "Nobody should tell me that I need to buy a Mac to be a web developer" - well said, but the ironicly speaking, you should have said that earlier to FireFox's Develeper Tools developers.

Steadfast Stanley - https://www.youtube.com/watch?v=T2E0x704I2s … - a third year animation student movie with Zombies, light-up-shoes and an awesome Corgi.

This has more story-telling than Dreamworks' last 5 movies. I hope this guy gets a great job and lots of money to do great things.
