    Production-Grade Container Scheduling and Management

    Project mention: FYI: InitContainers are racy in v1.28 (on reboot) | /r/kubernetes | 2023-09-28

    There was a nasty bug introduced in v1.28.0 as part of the Sidecar feature that caused InitContainers to race their startup with "primary" containers. Fortunately this only happens on node reboot.

  • Netdata

    Project mention: μMon: Stupid simple monitoring | news.ycombinator.com | 2023-09-24

    hey - I work on ML at Netdata (disclaimer).

    We have a big PR open and under review at moment that brings in a lot more logs capabilities: https://github.com/netdata/netdata/pull/13291

    We also have some specific logs collectors too - i think in here might be best place to look around at the moment, should take you to the logs part of the integrations section in our demo space (no login needed, sorry for the long horrible url, we adding this section to our docs soon but at moment only lives in the app)

    Project mention: Ask HN: I have 10 yrs of Exp. Failed 4 takehome projects. What am I doing wrong? | news.ycombinator.com | 2023-07-11

    >Again, here you seem to be arguing against a strawman that doesn't know that blocking the IO loop is bad. Try arguing against one that knows ways to work around that. This is why I'm saying this rule isn't true. Extensive computation on single-threaded "scripting" languages is possible (and even if it wasn't, punt it off to a remote pool of workers, which could also be NodeJS!).

    Very rare to find a rule that's absolutely true.. I clearly stated exceptions to the rule (which you repeated) but the generality is still true.

    Threading in nodejs is new and didn't exist since the last time I touched it. It looks like it's not the standard use case as google searches still have websites with titles saying node is single threaded everywhere. The only way I can see this being done is multiple Processes (meaning each with a copy of v8) using OS shared memory as IPC and they're just calling it threads. It will take a shit load of work to make v8 actually multi-threaded.

    Processes are expensive so you can't really follow this model per request. And we stopped following threading per request over a decade ago.

    Again these are exceptions to the rule, from what I'm reading Nodejs is normally still single threaded with a fixed number of worker processes that are called "threads". Under this my general rule is still generally true: backend engineering does no typically involve writing non blocking code and offloading compute to other sources. Again, there are exceptions but as I stated before these exceptions are rare.

    >Here's what I mean -- you can actually solve the ordering problem in O(N) + O(M) time by keeping track of the max you've seen and building a sparse array and running through every single index from max to zero. It's overkill, but it's generally referred to as a counting sort:

    Oh come on. We both know these sorts won't work. These large numbers will throw off memory. Imagine 3 routes. One route gets 352 hits, another route gets 400 hits, and another route gets 600,000 hits. What's Big Oh for memory and sort?

    It's O(600,000) for both memory and runtime. N=3 and it doesn't even matter here. Yeah these types of sorts are almost never used for this reason, they only work for things with smaller ranges. It's also especially not useful for this project. Like this project was designed so "counting sort" fails big time.

    Also we don't need to talk about the O(N) read and write. That's a given it's always there.

    >I don't think these statements make sense -- having docker installed and having redis installed are basically equivalent work. At the end of the day, the outcome is the same -- the developer is capable of running redis locally. Having redis installed on your local machine is absolutely within range for a backend developer.

    Unfortunately these statements do make sense and your characterization seems completely dishonest to me. People like to keep their local environments pure and segregated away from daemons that run in a web server. I'm sure in your universe you are claiming web developers install redis, postgresql and kafka all locally but that just sounds absurd to me. We can agree to disagree but from my perspective I don't think you're being realistic here.

    >Also, remote development is not practiced by many companies -- the only companies I've seen doing thin-clients that are large.

    It's practiced by a large amount and basically every company I've worked at for the past 5 years. Every company has to at least partially do remote dev in order to fully test E2E stuff or integrations.

    >I see it as just spinning up docker, not compose -- you already have access to the app (ex. if it was buildable via a function) so you could spawn redis in a subprocess (or container) on a random port, and then spawn the app.

    Sure. The point is it's hacky to do this without an existing framework. I'll check out that library you linked.

    >I agree that integration testing is harder -- I think there's more value there.

    Of course there's more value. You get more value at higher cost. That's been my entire point.

    >Also, for replicating S3, minio (https://github.com/minio/minio) is a good stand-in. For replicating lambda, localstack (https://docs.localstack.cloud/user-guide/aws/lambda/) is probably reasonable there's also frameworks with some consideration for this (https://www.serverless.com/framework/docs/providers/aws/guid...) built in.

    Good finds. But what about SNS, IOT, Big Query and Redshift? Again my problem isn't about specific services, it's about infra in general.

    >Ah, this is true -- but I think this is what people are testing in interviews. There is a predominant culture/shared values, and the test is literally whether someone can fit into those values.

    No. I think what's going on is people aren't putting much thought into what they're actually interviewing for. They just have some made up bar in their mind whether it's a leetcode algorithm or whether the guy wrote a unit test for the one available pure function for testing.

    >Whether they should or should not be, that's at least partially what interviews are -- does the new team member feel the same way about technical culture currently shared by the team.

    The answer is no. There's always developers who disagree with things and just don't reveal it. Think about the places you worked at. Were you in total agreement? I doubt it. A huge amount of devs are opinionated and think company policies or practices are BS. People adapt.

    >Now in the case of this interview your solution was just fine, even excellent (because you went out of your way to do async io, use newer/easier packaging methodologies, etc), but it's clearly not just that.

    The testing is just a game. I can play the game and suddenly I pass all the interviews. I think this is the flaw with your methodology as I just need to write tests to get in. Google for example in spirit attempted another method which involves testing IQ via algorithms. It's a much higher bar

    The problem with google is that their methodology can also be gamed but it's much harder to game it and often the bar is too high for the actual job the engineer is expected to do.

    I think both methodologies are flawed, but hiring via ignoring raw ability and picking people based off of weirdly specific cultural preferences is the worse of the two hiring methodologies.

    Put it this way. If a company has a strong testing culture, then engineers who don't typically test things will adapt. It's not hard to do, and testing isn't so annoying that they won't do it.

    Project mention: Ask HN: How do you manage your “family data warehouse”? | news.ycombinator.com | 2023-09-15

    A Synology NAS running Portainer (https://www.portainer.io/) running Paperless NGX (https://github.com/paperless-ngx/paperless-ngx)

    This works better than I can possibly tell you.

    I have an Epson WorkForce ES-580W that I bought when my mother passed away to bulk scan documents and it scans everything, double-sided if required, multi-page PDFs if required, at very high speed and uploads everything to OneDrive, at which point I drag and drop everything into Paperless.

    I could, thinking about it, have the scanner email stuff to Paperless. Might investigate that today.

    Paperless will OCR it and make it all searchable. This setup is amazing, I love living in the future.

  • Dokku

    A docker-powered PaaS that helps you build and manage the lifecycle of applications

    Project mention: Ask HN: How are you hosting multiple small apps? | news.ycombinator.com | 2023-09-23

    Based on the fact that your ideal is to have a similar experience to heroku than managing your own server setting up reverse proxies take a look at these options:

    1) https://dokku.com - lets you turn your light sail instance basically into heroku

    2) https://render.com

    3) https://fly.io

    4) If you have aws credits this is their heroku equivalent: https://aws.amazon.com/elasticbeanstalk

    above is not what I do but would be the options I would pursue if I understand your preference and requirement correctly.

  • helm

    The Kubernetes Package Manager

    Project mention: Signing container images: Comparing Sigstore, Notary, and Docker Content Trust | dev.to | 2023-09-26

    The choice of a winner depends on the specific requirements, priorities, and constraints of the organization or system you're working with. Sigstore is well-suited for organizations prioritizing secure and transparent software updates for various artifacts, including Helm charts, alongside images. It has great community support and features, such as interoperability between registries, making it a great choice for most organizations. Moreover, most container registries support the signing format.
