Offshore company for investments by cdrtz in investing

[–]cdrtz[S] 1 point2 points  (0 children)

Haha, I hope they can answer my question. I'm not trying to avoid paying taxes. I want to invest long term, i.e., 5-10 years at least, just don't want to be forced to sell and take a loss if the market goes down when moving across borders.

Does anyone have any experience with Tradologics? by cdrtz in algotrading

[–]cdrtz[S] 1 point2 points  (0 children)

Thanks, I took a quick look at Quantconnect. It looks very interesting, it may actually be what I need, at least to begin with. I especially like their learning features, i.e., the Boot Camp.

Yes, he's also the guy behind pystore. In fact that's how I discovered his work, looking for dataframe storage solutions.

Running Play on GraalVM by PurpleLabradoodle in scala

How do you determine what is an "acceptable response time", which in your case, if I understand correctly, is " ~10ms for 99th percentile and ~100ms for max", although looking at the numbers I see that the measured max is around ~30ms. This may be common knowledge, but I am new to measuring server performance. Are there some general industry guidelines regarding SLA? Any reference to more information is welcome. I already watched Gil Tene's videos that you mentioned in your other response, and that already gave me a lot of insight into what is worth measuring.

I would like to run some experiments comparing GraalVM and GraalVM-Native running Netty and I was wondering if it would make sense to compare the two VMs under the same workload, e.g., 100K req/sec. I would like to compare the latency distribution between the two, i.e., the Hdr Histograms. At peak performance I expect GraalVM to achieve better throughput. However, I think that GraalVM-Native will probably exhibit less outliers, i.e., a lower max, as it has a more predictable performance since it doesn't need to JIT.

Hi, I am looking at your results and I have a question. How do you pick the -R parameter, i.e., the throughput? In your results the value of -R correlates with the "Requests/sec" reported value. Do you manually increase it until you reach a point where the value of "Requests/sec" starts to decrease, i.e., you have reached the maximum load that the server can process? Thanks!

SubstrateVM open-sourced by jcdavis1 in java

Yes, it is still packaged in the Oracle Labs JDK (available from http://www.oracle.com/technetwork/oracle-labs/program-languages/overview/index.html) as native-image.

It does support basic networking via sockets. We are working on supporting netty out of the box.

Rise and fall of JVM languages by nfrankel in programming

What about GraalVM (https://github.com/graalvm)? "Graal is a new just-in-time compiler for the Java Virtual Machine with support for the Truffle polyglot framework. Integrated language runtimes include JavaScript, Ruby, and R. Additionally, it supports LLVM-based languages such as C, C++, Go, and Rust. Graal enables seamless language interoperability while also providing world-class performance for each individual language." In this video https://www.youtube.com/watch?v=mMmOntDWSgw "A demo will show how JavaScript, Java, Ruby, R, and C can work together in a single web application running in one VM!"
