  1. HACKBRIGHT TECH TALK: Music Information Retrieval in the IPython Notebook
    Researcher and engineer Steve Tjoa spoke about music information retrieval on Tuesday, October 21, 2014 at Hackbright Academy.

    About the Talk: Music information retrieval (MIR) is an interdisciplinary field bridging the domains of statistics, signal processing, machine learning, musicology, biology, and more. MIR algorithms allow a computer to make sense of audio data in order to bridge the semantic gap between high-level musical information — e.g. tempo, key, pitch, instrumentation, chord progression, genre, song structure — and low-level audio data.

    In this talk, we will survey common research problems in MIR, including music fingerprinting, transcription, classification, and recommendation, and recently proposed solutions in the research literature. The talk will contain both a high-level overview as well as concrete examples of implementing MIR algorithms in Python using NumPy, SciPy, and the IPython notebook.

    About the Speaker: Steve Tjoa is a researcher and engineer in the areas of signal processing and machine learning for music information retrieval (MIR). He currently works on the MIR team at Humtap. Before that, he worked on content-based audio recognition and recommendation as an NSF-sponsored postdoctoral fellow at iZotope and Imagine Research (acquired by iZotope). He has also worked as a consultant in the areas of audio/image signal processing, machine learning, and information retrieval.

    Since 2011, he has co-instructed the annual summer workshop on MIR at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University. He has served on committees for conferences such as ACM Multimedia and IEEE ICME; co-authored articles for journals and conferences such as IEEE Trans. Information Forensics and Security, IEEE ICASSP, and ISMIR; and peer-reviewed over 100 manuscripts. He earned a PhD in electrical engineering from the University of Maryland in 2011.

    Hackbright Academy runs a quarterly engineering fellowship in San Francisco. This is a 10-week accelerated software development program designed to help women become awesome programmers. At Hackbright they learn the fundamentals of computer science and modern web development, and are introduced to Silicon Valley companies looking to expand their engineering teams.

  2. HACKBRIGHT TECH TALK:
    Prototyping in the Data World - Data Scripting Skills!

    Mattermark data scientist & designer Clare Corthell spoke about data scripting, a powerful tool for prototyping data work, on Tuesday, September 9, 2014 at Hackbright Academy.

    About the Talk: Data is deeply integrated into decision making in modern companies. But businesses have difficulty understanding the glut of data they now create and consume. What is all this data, and how do we use it?

    This talk will cover how to get started with data scripting, a powerful tool for prototyping data work. Data skills are crucial as engineering teams are responsible for discovering, housing, and extracting business-critical data. We’ll discuss how to find meaningful data, develop heuristics for normalizing and slicing data, and define useful data structures. We’ll utilize the pythonic Data Scientists’ favorite tools, numpy, pandas, and iPython. Finally, we’ll talk about data work in industry, and why your scripting skills will be a superpower in a data-rich world.

    About the Speaker: Clare Corthell is a Data Scientist and Designer at Mattermark, a data-driven deal intelligence platform, where she builds technologies that quantify the growth of private companies. She is the originator of The Open Source Data Science Masters, a curriculum for learning Data Science. A Stanford-trained product designer and engineer, she's founded and worked with early-stage companies in the US, Europe, and East Africa. She’s up early pondering discovery algorithms, information design, diglossia, and education systems. Follow her at @clarecorthell.

  3. HACKBRIGHT TECH TALK:
    Netflix Data Analytics Platform Leveraging Big Data, Cloud and Open Source
    Netflix director of data engineering Eva Tse speaks about big data, cloud and open source. Recorded on Tuesday, July 22, 2014 at Hackbright Academy.

    About the Talk: Eva will examine three important technology choices that Netflix made to re-build the data analytics platform in the cloud. First, she will look at what Big Data technologies are used at Netflix for solving the problem, the rationale behind leveraging open source technologies, the open source projects that Netflix leverages, contributes to and creates.

    Eva will discuss why Netflix chose to build the infrastructure in the cloud, and what the advantages are of running in the cloud. Finally, tying all these together, she will deep dive into the architecture of the Netflix big data analytics platform.

    About the Speaker: Eva Tse leads the Big Data Platform team at Netflix. Her team architects and manages the Netflix big data platform in the cloud. The platform is leveraged across Netflix for data analytics and ETL. The technology stack includes various open source projects (e.g., Pig, Hive, Hadoop, Presto) and Netflix open source tools and services (e.g., Genie, S3mper). Prior to joining Netflix, Eva worked on the server and metadata service teams for PowerCenter at Informatica. Though she works with data systems, she has never taken a formal database class :) In her spare time, she enjoys playing with her son and watching movies and TV shows on Netflix.

  4. HACKBRIGHT TECH TALK:
    Best Practices for Software Engineers

    Twitter staff software engineer Shannon "JJ" Behrens will be speaks at Hackbright Acadmey. Recorded on Tuesday, July 8, 2014.

    About the Talk: Now part of the new hire orientation at Twitter, this talk by Shannon "JJ" Behrens covers how being a software engineer requires a lot more than knowing how to write good code.

    This tech talk covers a wide variety of topics such as making code reviews useful and effective, how to deal with team conflicts, networking in real life, and planning for your career. The goal is to help you not only be a solid asset for your team, but also to be the type of software engineer that others really enjoy working with.
