About Eiríkur Hallgrímsson

Let's talk about Public Good. Math/Science/Medicine, personal digital sovereignty and secure infrastructure. Lets not talk about AI/ML in the cloud for the purposes of spying on consumers. I'm a very senior Python developer who follows developments in the language and its libraries closely. I've dug into Go for highly responsive systems. I like the ideas in the Nim and Elm languages. I've been developing on Linux and TCP/IP for over 20 years. That's my favorite set of electric trains. I have a strong understanding of the Linux Desktop environments and infrastructure like D-Bus. I love tailoring Linux systems for quasi-embedded applications. I've used Numpy a lot and I've used PANDAS for ETL and processing big data sets. I've recently worked with PySpark (Apache Spark). Talk to me about anything Free Software or Open Source.I'm a very bright, continually self-educating, developer. I'm a math and science person. I love modern dynamic languages, but I work in C for low-level things. I like semi-embedded Linux devices like the Raspberry Pi because they expose both direct hardware interfaces and high-level APIs. I am a senior expert in all things Raspberry Pi. Coffeescript, Ruby and NodeJS are also in my toolkit. I'm the kind of person you should talk to about completely new blue-sky projects because I'm not locked-into any given technology. On the other hand, if you've just got some Python that needs to be fixed, I'd be glad to handle that for you.I especially enjoy working with unusual hardware and exotic input devices. Unicode, character sets and fonts are a major area of interest to me. At the moment I've got a number of projects running on the Raspberry Pi and Odroid's XU4 and N2. I build kernels for Raspberry Pi and other embedded systems. I use the low-latency, preempt, patch set for Linux frequently.Specialties: Raspberry Pi, Python, Desktop/Mobile Linux, Javascript applications programming via Coffeescript and jQuery, Linux tailoring and configuration. Ruby language. Scientific number-crunching in (fast) Numerical, NumPy, Python. XML-RPC, web services. TCP/IP, UDP networking from C, GTK+ user interfaces.

    Chicago, Il, Us
    Jackson brought me in to be their Python wizard as they moved to Python, but they quickly decided to go in a different direction. I participated in the design phases of a PySpark on Databricks solution to replace an existing SAS on mainframe financial modeling system for annuities. I profiled and benchmarked the PySpark code. To achieve the desired performance the code was rewritten as expressing SAS logic in SQL semantics inside a layer of Python syntax. I drove improvements in the very limiting development enviroment.

  • Veterans United Home Loans
    Python Web Applications Guru.
    Veterans United Home Loans Nov 2014 - Jan 2015
    Columbia, Missouri, Us
    As a part-time project I'm working for a data scientist at V.U., building a web application shell into which he can just drop new statistical tools as he develops them. He was already using Flask, so the shell is built on Flask (served by Tornado for performance) and SQLAlchemy. It provides Active Directory login via LDAP, hit and submit counts for each tool, and per-user access control set by an administrator. The drop-in tools use Flask's blueprint concept so that they can be dynamically loaded. Discovering and loading the tools involved some clever (I say) Pythonic introspection whereby I get a handle to the blueprint object, register the URL paths, and capture the module's docstring as well. I'm also writing a small library that the tools can call to get services from the shell and write to the database. The V.U. people are some of the nicest and most helpful that I've ever worked with. This project will be over in mid-January.

  • Wells Fargo
    Python Software Security Consultant
    Wells Fargo Mar 2014 - Jul 2014
    I reworked the automated security testing pipeline or gauntlet that a code change must pass through to be approved for production. There was an impressive array of static analysis tools that needed to be automated and controlled by a third-party harness that wants to work through Python "robots" that do all the actual work. WF had various pieces and shell scripts, but to get the full value of this new harness/supervisor things needed to be redone in Python. So I'm did that. The overall problem is made tractable in their estimation because their systems are mostly implemented in Java, which is a statically compiled language. I did what they asked for. My security geek hat thinks that this process needs some threat modeling. They are very nice people and provide a great virtual working environment. You would think that working on security for a bank would be encumbered with lots of restrictions. Wells Fargo is extremely professional about security. I didn't have to put up with any Security Theater or superstitious customs. Things that ought to just work do just work. I found this refreshing after working with the security found at large computer firms.

    Re-engineering the secure provisioning of administrator passwords for internal IT at HP. This is an internal add-on to HPSA, which is Opsware, which HP bought out a while back. HPSA doesn't do what they want in terms of account provisioning and they have an unreliable workaround. I fixed that, and brought over 200 servers back online. I worked for good people there, notably AJ Plichta.

    These folks loved my work, but the company reorg forced them to drop all contractors. It's a great reference. My work kept web services alive and well via probing. Paramiko SSH, MySQL, lots of Python. Remote system probing with ports to truly antique versions of Python. Developed a Python language extension to improve readability of domain-specific JSON-RPC code. Not quite a DSL, but close-ish. Yes, I'm the kind of person who extends the language in intelligent ways. I did a lot of object introspection on difficult objects retrieved from a code-generated Python API to the VMware Vsphere. You really haven't lived until you get an object with array in the name which is not iterable. I had to poke it with some seriously smart sticks, but at least now I've got some really smart sticks. And friends at Quest.

    Porting a mature client-server application to device-independent web technology. Translating the time-tested ergonomics of the original application into the browser environment has been quite interesting. In many ways the result is an application program (javascript) using the browser as a runtime environment, not a web browser. Coffeescript, HTML5, CSS3 and jQuery were the main technologies on the client. The server was a custom Coffeescript application using ExpressJS running on NodeJS.

    (Telecommuting contract for this interesting little company)Designed and programmed GUI and control software for a new IPv4 to/from IPv6 router. Initial version extended the Python/GTK+/Glade prototype. Analyzed project and convinced client that moving to an embedded web application for configuration (as planned for the next version) was more appropriate and not likely to take longer. Used Ruby on Rails for the GUI, Test First, and other agile methodologies. Project was put on hold due to the major investor pulling out. I'm still working with my colleague on how to deliver something affordably so that Ambriel can get to the point of showing their technology.

  • Spideroak
    Pythonist Avec Qt
    Spideroak 2007 - 2007
    Lenexa, Ks, Us
    I worked on the SpiderOak Client, notably the earliest versions of the screens that allow you to see what the client is uploading for you and what is in queue to be uploaded. Their use of Twisted Matrix as a transport had settled down by that point, but I had to come up to speed on how they used it. I'm not a big fan of Twisted, but their use is simple and elegant. I spent most of my time trying to get PyQT to work correctly. At that date it seemed to me that most of the PyQT bindings were automagically generated and not all of them had been tested. SpiderOak needed to get fairly low-level to get what we were after. I had to overrride a lot of paint methods in QT to get the desired cross-platform appearance. The biggest challenge was the event loop, Twisted has a custom reactor that allows it to work with the QT event loop, but it was delicate and I had to debug some subtle things. I particularly enjoyed working with their team, distributed as it was around the world. SpiderOak plug: They can't leak your personal information. They don't ever get your keys. That's the right way to go.

    Music Keyboard Development
    Personal Project; Part Time Aug 2005 - Aug 2006
    Developing an innovative music keyboard based on the Raspberry PI. Solving the audio and MIDI latency issues, and developing an appropriate user interface. Code is mostly in Python 3, controlling existing binaries that play samples, and route the audio and MIDI data. The Pi 2 has enough power to play large samples and compute analog filter models. I think the final UI will use the brand new Pi touchscreen, but the prototype uses GPIO up/down buttons for controls. The Pi does not have analog inputs for pots or simple means of using rotary encoders.

    Bespoke Free Software. Our motto is "rafknúið heili, 电脑, informatique couture." Modern dynamic languages preferred. Anything GPL. Anything that extends Linux to new applications. Have you thought about running the GNU Hurd on your device? I thought not. I wouldn't do this, since it's fighting the last war, but you never know. It would be much more secure than, say, Android. Modularity and functional composition of programs are your friends. Anything less is sort of like a prison for ideas. Python, Coffeescript, Ruby for applications, NodeJS just because it's brilliant and turns your whole world sideways. It's like the Unix 'worse is better' thing, but it's more like "uncomfortably brilliant is seriously better."
