devthaneon Linear Algebra 101 for AI/ML

Just finished working through part 1 and subscribed! Thank you so much! I've always been interested in learning ML but the math has been the hurdle for me that seems to have been assumed knowledge elsewhere. Saw the title and was immediately hooked! Can't wait for more.

devthaneon Testcontainers

Typically you mock them in unit tests.

devthaneon Ask HN: What side projects landed you a job?

I was a QA tester at a transportation company with a PHP stack. My leader was great and allowed me to teach myself web development when tasks were done. Eventually I built a finance calendar in php/symfony modeled after the websites the team built.

I demo'd it to him and I was allowed to start picking up development issues. Eventually became a full time developer. Kept learning and ended up containerizing all our applications and set up a kubernetes cluster, moving us away from VMs. ( responding to a desire from all the devs to start using docker ).

Circled back around and built automation for spinning up k8s testing environments for each the story in the QA queue to simplify things for our testers. By the time I the left the company, they hired a whole company to do everything I was doing, which I held off leaving until they were set up and I was able to knowledge transfer fully to the company. Moved to GoLang also now, don't really do php anymore.

Though still get keepalived alerts when a node goes down.

devthaneon DAWproject: Open exchange format for DAWs

I found it interesting to discover that an Ableton Live project file is a gzipped xml file as well, so you can get at the xml by gunzipping it.

I've played around with trying to generate a schema file from a project file with mixed results.

I very much wish Ableton would support this format or at least publish their schema somewhere so translation could be done.

devthaneon PostgreSQL: Kubegres is available as open source

https://kubernetes.io/docs/concepts/storage/persistent-volum...

I use https://rook.io/ to set storage up usually, they have a bunch of different options and good documentation.

devthaneon Germany pauses AstraZeneca vaccinations as a 'precaution'

It probably depends where you are located. There are some less developed countries countries that jumped the gun on hard lockdowns without any sort of care infrastructure I which people have died due to inability to get food or care for births.

For a source https://www.google.com/amp/s/mobile.reuters.com/article/amp/...

I don’t attempt to extend that to more developed countries however. And I can’t say they things wouldn’t be worse if they hadn’t locked down, but according to a family I know in Uganda, they were locked down before they had even one case. I haven’t done the research on whether that is true or not so take it or leave it.

devthaneon The Mayron Cole Piano Method is now free

This for certain. The piano is way more fun to play with weighted keys and much more expressive. I bought my first weighted key piano, a Roland FP-30, this year and have been playing almost every day just for the fun of it.

devthaneon Twitter limits users interacting with Trump's tweets about 'stolen' election

Whoever instigates violence is at fault, let me get that clear.

But I believe there is a responsibility on the side of organizers to be more vocal about peace than they are about the change they are trying to implement as other more righteous and respectable figures have done in the past.

If you allow your movement to become one of violence and all you have to say is to point the finger at others, whether you are correct or not, you are grossly inferior of the civil rights movements of the past.

But I believe, as many others do, that this movement was not born to achieve any measure of civil rights, though that may be the intent of many.

Making an enemy of an clear necessity of any society ( a police force ) and only being satisfied when injustice is performed on the offender is madness. There are corrupt police, do something productive about. Burning your own house down solves nothing, unless perhaps your goal is a new house.

devthaneon AWS pre-announces public container image registry

Agreed, we use it as well, it’s shaping up nicely, though its a good bit more user complicated than other solutions. But hey, this is Kubernetes.

devthaneon Ask HN: Which tools have made you a much better programmer?

I don’t notice slowness on it personally. Maybe you are noticing the initial indexing it does. That doesn’t happen often with GoLand.

Make sure you enable Golang modules in the settings also.

Anyways just mentioning some stuff off the top of my head I enjoy:

Debugging is a great experience.

Can find a plugin for most anything, I use the Kubernetes one for syntax completion and documentation. (alt-q I think)

Also you can create .rest files and compose http requests and trigger them right in the files, which I thought was cool.

The documentation pop up by hitting alt-q in general is pretty cool. Don’t have to run over to godoc.

Then most things you’d expect from an advanced ide. Multi line editing... jump to definitions and implementations... Project wide code search and replacement

devthaneon Norimaki Synthesizer: Taste Display Using Ion Electrophoresis in Five Gels

tastinator, I think you mean.

devthaneon A botnet is taken down in an operation by Microsoft, not the government

That’s really up to us as taxpayers though isn’t it? ( to push for legislation )

devthaneon Ask HN: What do you self-host?

You might take a look at https://github.com/grafana/loki if you haven’t seen it yet for logs. It’s still really new but it’s been working for me great.

devthaneon Blender 2.80

From looking at the release notes, while still not perfect, it looks like things have improved significantly with this update.

https://www.amd.com/en/support/kb/release-notes/rn-prorender...

devthaneon Blender 2.80

I have a friend with a recent macbook pro who has been following this situation.

I believe the answer for blender is https://www.amd.com/en/technologies/radeon-prorender-downloa...

Which I think is ready now as well.

Someone please correct me if I am wrong.

devthaneon Kubernetes Failure Stories

Not for production yet. I'm in the process of moving our infrastructure from VMs that no one was really managing to Kubernetes. We're about to put together the production cluster and move over a couple of the applications that are fully ready and have been tested on the development cluster for a while.

Currently the cluster I'm talking about is being heavily used for QA testing purposes and Beta testing of applications. Kubernetes and a small operator I've written allows us to dynamically create QA servers for issues as developers finish their changes. Beta testing is easily deployed by a helm chart I wrote up.

Next we'll start up the production cluster and use it for internal applications and finally we'll be moving over our customer facing applications.

devthaneon Kubernetes Failure Stories

I've had issues with longhorn as well, though the problem I was having (volume attachment race condition) is supposedly resolved by upgrading kubernetes.

I'm also trying out rook/ceph at the moment.

devthaneon Kubernetes Failure Stories

This isn’t my experience at all. I as one person taught myself over the past couple years docker then Kubernetes and am now managing a small 3 node bare metal cluster on my own.

But using rancher 2.0 has helped a bunch to ease me into it. Now I feel comfortable enough to start up a cluster on my own without it.

devthaneon Wine 3.0 Released

Just trying to help. I'm not an English major or anything myself, but here is one issue I noticed.

Don't overuse commas. After you get a complete idea out there, just end and start a new sentence. For example: "Please let me know how I can improve my phrasing and what mistakes I made. I am not a native speaker, so I am aware I can build my phrases in a weird way."

devthaneon A Message to Our Customers about iPhone Batteries and Performance

Just judging from my own experience, I do believe it is new. I have had a 5S for around 3 years now, my wife just finished her 2 year contract on her 6.

She has been noticing a slow down on her phone, while I have not on mine. I thought this was strange before reading this press release, but now it seems to fit.
