betatim | 7 years ago | on: Binder – Turn a Git repo into a collection of interactive notebooks

Some demos and examples:

https://jupyter.org/try all the repos linked from there are backed by mybinder.org (The interpreted C++ one blows my mind)

Some examples if you want to know how to configure things: * Install Python dependencies via requirements.txt https://github.com/binder-examples/requirements

* Jupyter with R and RStudio: https://github.com/binder-examples/r

* Julia support: https://github.com/binder-examples/demo-julia

* Installing additional APT packages: https://github.com/binder-examples/apt_install

https://mybinder.readthedocs.io/en/latest/about.html#who-pay...

At the current level of usage and compute resources it costs about $50000 per year to run the services, if you don't have to pay the humans that help build and run it. We are an open project, if anyone wants to join to learn more about Kubernetes, Jupyter, Ops, Python, Docker you would be very welcome. We hang out on https://gitter.im/jupyterhub/binder and https://github.com/jupyterhub/binder is a meta repository.

SEEKING WORK - Switzerland, Remote

Tim is a scientist at the Large Hadron Collider and open source tool maker. I help develop open source software that is used by thousands of businesses and organisations to effectively model and learn about their data (http://github.com/betatim). I also lead a team of five to innovate on pattern reconstruction, particle detection, and experiment design which helped CERN develop a system able to process data at an unprecedented rate.

Tim consults on machine-learning, statistics and software development. Tim helps companies make data driven decisions by taking advantage of the data they have, building predictive models with that data, integrating expert knowledge, solving computational challenges and interpreting the results.

SEEKING WORK - Geneva or Remote

I consult on machine-learning, statistics and software development. I help companies make data driven decisions by taking advantage of the data they have, building predictive models with that data, integrating expert knowledge, solving computational challenges and interpreting the results.

Background: Tim has a PhD in Physics and several years experience as a post-doc working at CERN. My PhD research focussed on analysing large amounts of data using advanced statistical methods and machine-learning techniques. As a research fellow at CERN and EPFL I created and lead software teams responsible for designing the upgrade of the LHCb experiment. I value clear communication and often find myself interpreting between different groups of experts. I contribute to several open source projects which form the scientific python stack. I created a successful training program for scientists which dramatically reduces the on boarding time for new members of the collaboration.

Contact me for a free consultation.

betatim | 11 years ago | on: How Many Mutual Funds Routinely Rout the Market? Zero

Can someone explain why they flip a coin twice per year per fund?

The author wrote a second column (http://www.nytimes.com/2014/07/27/your-money/heads-or-tails-...) explaining how they came up with the number of funds that would outperform the market five years in a row.

The reasoning goes like this: 2/2862 funds made it (or about 0.07% of funds).

The author then says: If you assume a fund has a 50% chance of beating the market, and a 50% chance of falling behind then the chances of one beating the market five years in a row would be 0.5^(5 * 2). They just state that they flip a coin twice per year per fund (hence 0.5^10), can someone explain why?

Conclusion, I forgot to turn off my VPN at some point when testing the resulting link. If you are not at CERN (like me) it will just show a preview :(

If you want to learn about graphene's amazing properties go ahead and read the paper here: http://rdcu.be/bKud

betatim | 11 years ago | on: Nature makes all articles free to view

Regarding the creation of the links to read the articles. For me the readcube link is just made from the DOI you get on the public webpage. It is so simple that I even wrote a little bookmarklet to do it: https://betatim.github.io/posts/read-any-nature-paper-for-fr...

For example for http://www.nature.com/nature/journal/vaop/ncurrent/full/natu... the readcube link is simply http://www.readcube.com/articles/10.1038/nature14015

It seems too easy? What am I missing?
