Calling C from Julia is pretty straightforward https://docs.julialang.org/en/v1/manual/calling-c-and-fortra...

You beat me to it! Julia is both dynamic and fast. It doesn’t solve all issues but uniquely solves the problem of needing 2 languages if you want flexibility and performance.

I don’t get it. Go is as imperative as a language can be.

No. Virtualenvs, and requirements are a thing in Python for ages. I’ve used tons of languages and while not the best, Python dependency management and project isolation is decent. IMO certainly better than JavaScript.

I’ve worked on airline scheduling system and solving to optionally is indeed NP-hard and scales badly. However you can get to a very good spot with heuristics. This particular issue with SW looks like bad data collection(crew has to phone t

Though about that as well. Few years ago I implemented a SIMD sort using those and mergesort.

Of note, Java !== JVM. Spark and Flink, for instance, are written in Scala which is alive and well :). My best effort in finding replacements of those tools that don't leverage the JVM: HDFS: Any cloud object store like S3/AzBlob,

No electronic system is deemed impossible to hack. That said, the system we have in Brazil relies on way more than just technical measures to ensure the security. There are statistical controls, processes are transparent and follow standard

Julia had a dev mode as well https://pkgdocs.julialang.org/v1/managing-packages/#developi... It’s packaging tool is top notch. Maybe because it’s developed as a core part of the language.

On enterprises, k8s solves a different kind of scaling problem. You tend to have hundreds of apps that are business critical and need to be managed. K8s provides a consistent way to package, deploy with HA and monitor those apps. Ideally it

Modern CPUs are giant, complicated pieces of hardware. But they’re useful, and have a well defined interface that you can interact with it at a higher level. Same with k8s. People conflated running k8s from scratch, with administrating. The

Friends don’t let friends run their own k8s instances. You should use cloud managed deployment and rely on their security services. For comparison, you can just as easily expose/hide your VM as your managed k8s cluster.

We recently used Julia to solve (correctly) a super complex scheduling problem for a major airline. Our budget was 5min, Python would get not even close to a solution in that time. The tool is being actively used in production. Julia is not

I’d slow down a bit, but I do like what I do at $dayjob. We got the option to work 9 out of 12m so I may eventually take that.

You would be amazed at the number of managers that largely ignore the "feel-good" part of the job, or even contribute to the workplace being a crappy place to work. Like the author said, actively improving the working environment

We use Spark extensively. We also use @pandas_udf to run some part of our Spark pipeline through some Python-only ML libraries.

As many already said, 99% is just a modern IDE with a one-click-install plugin. Also, I don't know the grip with productivity tools.

Ossification is an interesting problem. We dealt with it in the past with IE6 basically via “shaming” users/corps into switching. A message in Netflix/Google/Facebook home telling “we see your network is blocking X, that may

Cloud “value added services” ie, all but elastic VM, networking and storage, are typically very poor compared to whatever you can find in k8s just one helm install away.

This ship has sailed. SPAs shortcomings are widely known and addressed by frameworks. Whatever MPA alternative you bring will need to address other shortcomings. There will always be something quirky due to building applications in a techno

Came here to say the same thing. With multiple dispatch and JIT compilation, you’ll go a long way in Julia with the naive version of the code.

That's the only possible alternative. You're an expert at a hot topic living in Zurich. There are plenty of alternatives to get work at even better rate. Also forget the legal course. There's no upside.

That was not my argument. And the organization of state and Plato's politics are way more connected. But my comment was that people have such a "need for being ruled" that we repurpose ideas with clear autocratic root for our

Interesting that Popper denounce Plato's political theory as totalitarian. But if you look at it, that's basically how we divide society and government. We cherish technocrats and "philosopher-king" to rule us in the Sup

The problem was throwing the solution at their faces like that. The key to looking stupid is not making others look stupid. There are ways to create roundabouts so that the solution looks “elegant” but only after “hard thought”. There’s als
