    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).

  • GitHub repo Gogs

    Gogs is a painless self-hosted Git service

    Project mention: GitHub Reinstated YouTube-DL but Restoring Forks Is Apparently a Problem | news.ycombinator.com | 2021-04-17

    Sure, I reported an issue to the Gogs maintainer over two weeks ago and he hasn't acknowledged it at all. Here's the public reference that their SECURITY.md asks for: https://github.com/gogs/gogs/issues/6534

    Here's another one posted about a week ago: https://github.com/gogs/gogs/issues/6536

  • GitHub repo letsencrypt

    Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol.

    Project mention: ECDSA or RSA | reddit.com/r/crypto | 2021-04-10

    Certbot does support secp521r1, at least after looking at its changelog.

  • GitHub repo Gitea

    Git with a cup of tea, painless self-hosted git service

    Project mention: GitHub Reinstated YouTube-DL but Restoring Forks Is Apparently a Problem | news.ycombinator.com | 2021-04-17

    The gogs maintainer currently seems to not be doing much with it and seems to be ignoring security reports. I would probably recommend the gitea fork instead.


  • GitHub repo Docker Compose

    Define and run multi-container applications with Docker

    Project mention: Creating {legacy} static build via docker and deploying with mina-scp | dev.to | 2021-04-15

  • GitHub repo psutil

    Cross-platform lib for process and system monitoring in Python

    Project mention: Profiling Python code with memory_profiler | dev.to | 2021-04-21

    It uses the psutil library (or can use tracemalloc or posix) to access process information in a cross platform way, so it works on Windows, Mac, and Linux.

  • GitHub repo linuxkit

    A toolkit for building secure, portable and lean operating systems for containers

    Project mention: Docker Without Docker | news.ycombinator.com | 2021-04-08

    I'm really impressed by fly.io, and the candidness with which they share some of their really awesome technology. Being container-first is the next step for PaaS IMO and they are ahead of the pack.

    I aim to build a platform like theirs someday (probably not any time soon) but I don't think I'd do any of what they're doing -- it feels unnecessary. Bear with me as I recently learned that they use nomad[0] and some of these suggestions are kubernetes projects but I'd love to hear why the following technologies were decided against (if they were):

    - kata-containers[1] (it does the whole container -> VM flow for you, automatically, nemu, firecracker) with multiple VMM options[2]

    - linuxkit[3] (let's say you didn't go with kata-containers, this is another container->VM path)

    - firecracker-containerd[4] (very minimal keep-your-container-but-run-it-as-a-VM)

    - kubevirt[5] (if you just want to actually run VMs, regardless of how you built them)

    - Ceph[6] for storage -- make LVM pools and just give them to Ceph, you'll get blocks, distributed filesystems (CephFS), and object gateways (S3/Swift) out of it (in the k8s space Rook manages this)

    As an aside to all this, there's also LXD, which supports running "system" (user namespace isolated) containers, VMs (somewhat recent[7][8]), live migration via criu[9], management/migration of underlying filesystems, runs on LVM or zfs[10], it's basically all-in-one, but does fall behind in terms of ecosystem since everyone else is aboard the "cloud native"/"works-with-kubernetes" train.

    I've basically how I plan to run a service like fly.io if I ever did -- so maybe my secret is out, but I sure would like to know just how much of this fly.io got built on (if any of it), and/or what was turned down.

  • GitHub repo supervisor

    Supervisor process control system for UNIX

    Project mention: Some questions regarding building a bot? | reddit.com/r/redditdev | 2021-03-15

  • GitHub repo GVM

    Go Version Manager

    Project mention: Recommended way to manage go versions on mac and linux | reddit.com/r/golang | 2021-03-27
