Thanks for introducing me to `add-lib` This is going to be a huge time saver :) More info here: https://insideclojure.org/2018/05/04/add-lib/ Hopefully there will be some way to just "reload" y

Yeah, I mean from a IDE/developer point of view reflection is fantastic - really can't argue with that. At dev time it's a life saver. But coming from C++ my gut reaction is that for compilation/distribution time this is

That's an important distinction. I guess my annoyance is mostly cosmetic. The app is pretty small and does a simple data processing task. Had I written the app in C++ it would have been a couple of megabytes (and it would have taken me

Crazy to think they choose an unshrinkable language as a mobile platform :) It doesn't seem like that powerful of a language feature (and more of a code smell) and it creates this mess down the line. I wonder what fraction of libraries

Oh that's cool. I'm not intimately familiar with Java, so it's interesting to see how it's done. I figured it was something like that. Coming from C++, reflection seems like a giant useless codesmell - and there are all

As I understood it, jdeps is only for shrinking the runtime and bundling it with the program. This part seems fine.. or at least they're doing the best they can :) I ended up skipping this step and distributing a JAR - which is a bit o

by geokon 5y ago
No, the Java compiler does not do this. You can try it yourself and see. All dependencies are bundled into the JAR. If you have some large library as a dependency (like BoofCV or JavaFX for instance) then all of the classes and dependencies

Anyone have any experience using a Java treeshaker? I have a Clojure GUI/JFX App that's bloated and I've only managed to slim it down with manual package pruning. I couldn't get Proguard to work with Clojure. Granted pr

Usually when companies talk about an "enormous environmental toll" i get the feeling the business case must be weak. But giving them the benefit of the doubt and assuming the tech is legit and it all makes economic sense, why Norw

Well they don't need to be idempotent, but it's generally a good idea if you want to stay sane debugging your system. To the second effect, I know in clojure's reframe this is handled by something called "subscriptions&q

Don't you accomplish nearly the same thing with memoized functions? This seems to just provide a wrapper that obfuscates things

Isn't this basically a normal tagged image? Like one you'd see on instagram/facebook. It displays a little bubble at a given position with the user name of the person in the picture. When you mouse over it changes to indicate

There are new RISC-V chips that aim to do that: https://www.cnx-software.com/2020/10/24/bl602-bl604-risc-v-w... Here is a recently announced board: https://www.cnx-software.com/2021/05&#x

Thanks for the explanation. It raises other questions, like how they would know small MACHOs haven't darkened the sky (I'm guess either you'd see twinking or it'd shift the stars downward on the Hertzsprung–Russell diagr

Nebulae are an argument in favor. They are observable b/c they're not dense. They have a very high surface area to mass ratio. Light passes through them and they have absorption spectrum. They also emit a lot of black body radiat

Maybe someone could help me understand why a simple explanation for dark matter isn't possible. I get how you can measure the mass of stars, and how you could also maybe measure the mass of interstellar gasses. You add it all up and th

right. I think that was the parent's point. There is a bit of a double standard. You aren't allowed to link to a torrent of some software that's posted to hn. But if it's someone's writing then it's whatever. I

well I didn't mean to be rude. but it was an off the cuff remark that was wrong. People say things without posting a source and that's how disinformation starts... first thing that came up in search suggests archive.org also is mo

1) I assume b/c libraries purchase the book it's not equivalent. Do they purchase a subscription to the NYT and then lend it out to people? From what I gather on their website it doesn't seem like it 2) I'm not sure why

I see, so it wasn't some unexpected influx. It was a deliberate decision on the part of the authorities. I guess it makes sense that industry is clustered and you often can't bring the factories to where the people live.

Couldn't you use the exact same argument for software? It too gets taken down all the time I never really understood how Archive.org operates. This is an honest question.. But they doesn't own this piece of writing, so what'

It's a bit surprising that this omits the fact that the Moscow Metro is a nuclear bomb shelter. There are huge blast doors everywhere and at many stations it's significantly deeper than Paris of New York. It's also got some o

I guess what bothers me is that visualizations are supposed to leverage our intuition and gut feeling. Like in Geometry, the teacher tell you that when the lines are parallel, the angels on on a bisecting line are the same. You "see&qu

Oh woah, I've never seen that visualization - very cool. I only meant to really highlight that often things are thrown on the complex plane and presented in introductory material as making the problem in 2D. The few times I've see

I didn't mean to imply that there is anything wrong with visualization. I feel they're easier to understand than equations for the vast majority of people. But as a concrete example, to understand the Fourier transform it probably

At the end of these types of popsci explanations you still can't grok the math any better and you end up with a hand-wave-y misleading understanding of what's going on. It starts off by saying that the Fourier Transform "meas
