Ian Ozsvald's data thoughts

Hello. You signed up to this list for Python-related Data Science thoughts and jobs (administered by Ian Ozsvald at Mor Consulting), you probably joined via Ian Ozsvald's blog.

You can UNSUBSCRIBE (please, do Unsubscribe if you don't need this any more!) if my thoughts and jobs aren't interesting. You can also update your profile to change your email address. Subscribe here - maybe a friend needs this link?

NumFOCUS fundraiser, faster Pandas strings, new memory debugger

James Powell of Numfocus is leading a fund raiser this weekend - pay what your want to watch him live code for 4 hours. He’s got a set of famous names joining for the live event - you’re likely to learn a ton!

Core Pandas developer Uwe Korn has done some fabulous work with the Fletcher library to build out a new Pandas string library. He’s used an old Kaggle example I’d worked in with Numba to accelerate string comparison operations along with Dask, this is well worth a read.

Early next year I’m running my next highly rated Software Engineering for Data Scientist’s class. This is for you if you need a stronger and standardised development process, want to develop faster using tests and want to refactor to make your code reusable.

The course runs on 3 UK mornings using Zoom and Slack in late February. There’s a limited set of Early Bird tickets and if you’re fast you can use this Christmas discount code for 10% off (XMAS2020_10PERCENT). Mail me back if you’ve got questions but don’t dally if you want to attend.

My old colleague Paul Ross got in touch about his new memory tracing debugger tool. If you need to hunt down memory leaks, maybe you’ll want to check his tool. He says: “As data sets become larger and larger the memory demands for processing increases enormously. PyMemTrace provides a collection of tools that help you understand where and by how much memory is being used during processing. The tools vary in granularity and invasiveness from just the overall total memory usage or down to line by line reporting of every malloc() and free(). These tools can highlight where excessive memory usage is slowing down data processing.”

My High Performance Python 2nd ed is on GoodReads where we'd dearly love a review please :-) Do let me know if you write a review and I can add it to my blog post.

Data Science Strategy and Coaching for Teams

I work with data science teams to quickly deliver strategic plans and I coach teams and executives in the execution of these plans - covering process, technique, communication, prioritisation, tooling and lots more. Get in contact if you think this might help your team. See the Recommendations on my LinkedIn profile for kind words from clients I've helped.

JOB BOARD

The roles are listed below. Contact details are listed against each job.

If you've got a job to share (this list has over 1,000 data scientists and data engineers) then get in contact. If you're an active data scientist who helps build our PyDataLondon community then you (not a colleague - just you!) get your first post for free and I take the time-cost as a contribution towards building our community. If you're from outside the community or a recruiter then commercial rates apply. In either case I vet the advert to make sure it is suitable for this list.

Do you need training? List-owner-Ian provides Python, data science and high performance training using both general Python tools and the Anaconda environment. You can reply to this email to contact Ian directly or join the training announcement list.

If you're interested in these sorts of roles then you might also want to come along to our PyDataLondon meetup each month as community members shout out their jobs at the end of each night, we have over 10,000 members.

Cheers, Ian Ozsvald
