  Project mention: UNH CEPS / General Advice | reddit.com/r/unh | 2021-04-14

  The job market in New England was terrible for junior devs in 2010 and there were only 6-7 CS graduates that year down from the ~130 that started in freshman year. Anyway, I graduated and looked in NH, Boston, Stamford, and NYC and couldn't find anything, but ended up finding a neat gig outside of DC working for BAE as a kernel developer for a proprietary operating system called STOP (https://www.baesystems.com/en/product/stop-os). I worked there for two years before realizing I hated the area and also the DoD's budget got slashed so we were looking at staff reductions. I reached out to a fellow 2010 UNH CS graduate and ex-IOLer working at NetApp and he hooked me up with an interview down in Raleigh for a SAN interoperability role which was basically getting paid a lot more money to do what I did at the IOL. Two years after that NetApp did a ton of layoffs and my whole group got cut in half. Some of the smarter people went to a startup called Nimble Storage, so I decided to follow the smart people and resigned from NetApp and went to Nimble. I was there for 4 years and really got my hands in helping develop the test library and transition it from Perl to Python. Sounds boring, but it was pretty interesting and was my first crack at managing projects across timezones. Nimble got acquired by HPE and after a year of watching our benefits get slashed or taken away completely I resigned to work at Nutanix and join a guy that I had worked at NetApp and Nimble with previously. I was there less than a year before I left for personal reasons and joined a cloud/kubernetes monitoring company called Sysdig that was founded by the Wireshark guy and currently has Nimble's old CEO in charge. The Sysdig office in Raleigh is basically entirely comprised of people from NetApp and Nimble, so it was like a reunion. While there I developed a test framework in Python that leveraged pytest, terraform (https://www.terraform.io/), ansible (https://www.ansible.com/) to deploy resources across multiple clouds and kubernetes environments, install Sysdig components on them, then test the products. I left Sysdig last summer and rejoined Nutanix in a different capacity and now have a bit more project ownership, though I am still in an individual contributor role (not a manager).

• neovim

• Meteor JS

  9 42,388 9.3 JavaScript

  Meteor, the JavaScript App Platform

  

  Project mention: Totally stuck with listIndexes calls. Our volunteer social project building community migrated from Mlab to Mongo DB's Atlas in Nov and all our sites died. I've tried everything i can think to get the platform back up. Can anyone help or offer advice? | reddit.com/r/mongodb | 2021-04-21

  Could this _ensureIndex be the problem? I think that may be calling into listIndexes here: https://github.com/mongodb/node-mongodb-native/blob/2b18411d2f57e06d11262d5a308c56a9f561789e/lib/operations/db_ops.js#L305. IIRC, ensureIndex is deprecated, and you should use createIndex instead. I'm not familiar with meteor, so I'm not exactly sure what that code looks like, but the README shows how to access the underlying MongoDB driver directly: https://github.com/meteor/meteor/tree/devel/packages/mongo#direct-access-to-npm-mongodb-api. Hope that helps!

• Home Assistant

  193 41,979 10.0 Python

  Project mention: Tones on the Nest Hello? | reddit.com/r/Nest | 2021-04-21

• Scrapy

  25 40,392 9.2 Python

  Scrapy, a fast high-level web crawling & scraping framework for Python.

  

  Project mention: Why is Python popular despite being accused of being slow? | reddit.com/r/programming | 2021-04-16

  I use it regularly for things like web scraping (Scrapy is a joy) and data manipulation. For instance just wrote some fairly complicated scripts for doing address matching to pair up a couple of UK datasets without a common identity field. Human-entered addresses are decidedly fuzzy so you end up with a lot of arbitrary rules and Python is just fast to develop against. I don't really care if the script takes a couple of hours to run on the full datasets (35 million addresses) as opposed to half that time in something else more of a pain to tweak around with.
