The playlist rom the recent GOTO Aarhus 2012 has been published on YouTube.
Jez Humble's "Implementing Continuous Delivery" where he talks about the organisational problems, mistakes
and misconceptions that come up when trying to implement Continuous Delivery has been one of my favourites.
[...] In December 2011 I wrote down a bunch of assumptions about Why programmers work at night (link) in a blogpost. I
wrote it because I got tired of being called a lazy slob for waking up at 11am every day.
After 4000 tweets, 10000 likes and many emails I didn't feel alone anymore.
The most surprising feedback were emails along the lines of "Oh man! I finally understand my husband, thanks so much
for writing this!". And it is because of those that I have finally decided to write a short ebook.
In the book I'm going to:
Show fellow night-time programmers (and others!) that they are not alone
Give practical tips on living with your friendly neighborhood programmer
Support my original hypotheses by interviewing cool programmers
Explore the modern trend of super early wakeruppers who approach the night time from the other end
So if you're a programmer that feels missunderstood on your late nights of happy coding, maybe this book will be an
ideal gift for your roomies, girlfriend, boyfriend, parents or even for your boss.
I first learned about Petr Mitrichev the past year when he won 2011's Facebook Hacker Cup. He's a Google developer
leading the current competitive programming challenges. He also keeps an interesting blog at
petr-mitrichev.blogspot.com where he talks
about algorithms and sometimes challenges his readers with some problems.
I also found some interesting reading material if you're into competitive programming.
Codeforces has a great post about Sao Paulo Training Camp 2010
containing his solutions to problems and some video explanations.
Update March 2013: He came up on top at 2013's Facebook Hacker Cup as well. This is guy is amazing :)
We met Robert Sabella from
OTA Training and we chatted for a bit
while we waited for others to arrive. Rob started the day by introducing NFC and the
work the NFC Bootcamp has being doing
for the past year.
Bastien Latge from INSIDE Secure
followed up with a more in depth talk about the key players in an NFC Ecosystem and underlined some of the most
common problems and situations companies deploying NFC solutions encounter the most. He talked about the NFC parts,
specially the Secure Element and the different implementations and security measures implemented in
them. He also talked briefly about the hardware which provides NFC capabilities for mobile phones without
built-in NFC tech.
Just before lunch, we met Stéphane Doutriaux from
Poken. He made a brief introduction about
Poken with a video. Afterwards we all got our own pokens and did a little tour of the reception
area and the schedule wall poster, poking along the way and getting comfortable with the devices.
After lunch, Gloria Lozano from BCN Touch
gave her talk, focusing on use cases and their projects from the last past years.
Then Stéphane came back to talk a bit more about the marketing and user experience side of NFC and how he thinks
we should put the most of our efforts in providing some value rather than some technology, and use NFC as a means
and not as a goal.
At the beginning of day 2, we got a USB NFC reader and different cards with different NFC chips in them and Bastien
finished his talk about the players in the NFC environment.
Then we met Fernando Cejas, a mobile developer based in Barcelona, working for
Flomio. He's also de organiser of the Google Developers Group Barcelona.
His talk was going to be more focused on de technical/developer side of NFC but due to the majority of the assistants
being not so technical that part was skipped. Bummer.
Before lunch, we went for a walk around the Smart City Expo and Fernando was captured by an evil robot.
After we rescued him, Fernando gave a more technical explanation of the NFC components, the different NDEF
well known formats and the read/writing permissions.
He also talked about the idea of "cloud tags", flomio, the
FloJack to provide NFC for
iphone/ipad devices and other solution prototypes they had researched using other tech such as the
Raspberry Pi and the GuruPlug
Then Stéphane came back and we participated in a workshop with Poken and their partner tools. We created a campaign
and linked a Poken Tag using the NFC Reader/Writer. We also learned a bit more about the technology used in Poken.
The Poken tags use the same technology as the regular Pokens.
They use a Swatch licensed
chip with added NFC capabilities and a full USB stack,powered by a 9 volt battery that lasts about two years.
Everything is encased in silicon so its fairly resistant, and of course, it's sticky. Poken Tags have to be
activated using an NFC writer and power themselves off when they are stacked or they detect too much inference
to not drain the battery.
We all got an NFC Bootcamp completion certificate on behalf of OTA Training and the
AENFC and we took some pictures. It was a great experience and I'm sure both
speakers and attendees will keep in touch with each other.
PHP + Symfony developer Matthias Noback has
written a really nice article about the use of Silex on outdated PHP projects. If you've been looking forward to
migrate/redo some of your old projects using Symfony components, this may be worth reading.
I couldn't agree more with the author. The past year I stayed late at the office a lot of times doing a lot of good
work. This year not so much because my girlfriend moved in with me, so I've gotten some rest from that but I kind of
miss it too. When we were working on Aura, we would work until very late and wake
up for lunch almost every day.
