  • Nanos

    Project mention: What do you monitor on devices? | reddit.com/r/networking | 2021-11-30

    Side note, if you're going to redesign your Zabbix setup, I recommend upgrading to Prometheus. Think of it like a modern Zabbix, which includes a new protocol designed to replace SNMP.

  • GitHub repo tidb

    TiDB is an open source distributed HTAP database compatible with the MySQL protocol

    Project mention: Comparing Nginx Performance in Bare Metal and Virtual Environments | news.ycombinator.com | 2021-10-29

    I do agree with you in that regard, however, that's also a dangerous line of thinking.

    There are attempts to provide horizontal scalability for RDBMSes in a transparent way, like TiDB https://pingcap.com/ (which is compatible with the MySQL 5.7 drivers), however, the list of functionality that's sacrificed to achieve easily extensible clusters is a long one: https://docs.pingcap.com/tidb/stable/mysql-compatibility

    There are other technologies, like MongoDB, which sometimes are more successful at a clustered configuration, however most of the traditional RDBMSes work best in a leader-follower type of replication scenario, because even those aforementioned systems oftentimes have data consistency issues that may eventually pop up.

    Essentially, my argument is that the lack of good horizontally scalable databases or other data storage solutions is easily explainable by the fact that the problem itself isn't solvable in any easy way, apart from adopting eventual consistency, which is probably going to create more problems than it will solve in case of any pre-existing code that makes assumptions about what ways it'll be able to access data and operate on it: https://en.wikipedia.org/wiki/Fallacies_of_distributed_compu...

    To that end, i'd perhaps like to suggest an alternative: use a single vertically scalable RDBMS instance when possible, with a hot standby if you have the resources for that. Let the architecture around it be horizontally scalable instead, and let it deal with the complexities of balancing the load and dealing with backpressure - introduce a message queue if you must, maybe even an in-memory one for simplicity's sake, or consider an event based architecture where "what needs to be done" is encapsulated within a data structure that can be passed around and applied whenever possible. In my eyes, such solutions can in many cases be better than losing the many benefits of having a single source of truth.

    Alternatively, consider sharding as a possibility, or, alternatively, do some domain driven design, figure out where to draw some boundaries and split your service into multiple ones that cover the domain with which you need to work with. Then you have one DB for sales, one for account management, one for reports and so on, all separated by something as simple as REST interfaces and with rate limits or any of the other mechanisms.

    If, however, neither of those two groups of approaches don't seem to be suitable for the loads that you're dealing with, then you probably have a team of very smart people and a large amount of resources to figure out what will work best.

    To sum up, if there are no good solutions in the space, perhaps that's because the problems themselves haven't been solved yet. Thus, sooner or later, they'll need to be sidestepped and their impact mitigated in whatever capacity is possible.

  • GitHub repo Gitea

  • GitHub repo cli

    GitHub’s official command line tool

    Project mention: Ask HN: What the best and worst command-line interfaces you have used? | news.ycombinator.com | 2021-11-24
  • GitHub repo cockroach

    CockroachDB - the open source, cloud-native distributed SQL database.

    Project mention: Composing generic data structures in go | dev.to | 2021-11-30

    Recently a colleague, Nathan, reflecting on CockroachDB, remarked (paraphrased from memory) that the key data structure is the interval btree. The story of Nathan’s addition of the first interval btree to cockroach and the power of copy-on-write data structures is worthy of its own blog post for another day. It’s Nathan’s hand-specialization of that data structure that provided the basis (and tests) for the generalization I’ll be presenting here. The reason for this specialization was as much for the performance wins of avoiding excessive allocations, pointer chasing, and cost of type assertions when using interface boxing.

  • Scout APM

  • GitHub repo PhotoPrism

    Project mention: Recommendation: Software for managing and searching a large number of photos | reddit.com/r/msp | 2021-11-30

    https://github.com/photoprism/photoprism checks all the boxes and uses Google's TensorFlow and AI to tag and categorize the photos. All data remains local and does not make a trip to the cloud. Development is very active. The only down side is it's still in beta. On the plus side, they have a Commercial License with business support.

  • GitHub repo croc

    Easily and securely send things from one computer to another :crocodile: :package:

    Project mention: What’s an extremely useful website most people probably don’t know about? | reddit.com/r/AskReddit | 2021-11-19

  • GitHub repo containerd

    An open and reliable container runtime

    Project mention: Run containers on your Mac with Lima | reddit.com/r/apple | 2021-11-28

    Many of the things you mention there are actually not provided by Docker. The clear and well defined format is OCI, which stands for “Open Container Initiative” (Docker was a founding member, but they aren’t the only one). The underlying runtime for containers that Docker uses is containerd which is an open source product. Docker provides… Docker Hub, and a client app. Docker certainly isn’t the only option, there’s also Kubernetes, Podman, or even just (shudder) containerd itself. Heck, you could write your own.

  • GitHub repo thanos
