@arlia 我觉得s23手感还行，但是我是喜欢那种有棱有角方方正正的那种（

I recently removed my phone number from my résumé be those HRs keep calling me without texting me first. (I do leave my email address on it)

Recently I switched to a new job finding platform, and it has a feature that allows you to send your resumes in batches. Most of the time, I don't check the recommendations, and I just yolo it. So when someone calls me without telling me beforehand, I don't know who they are... and I don't pick them up. (Yeah, I generally ignore all unknown incoming phone calls to keep way spams and promotions. If that's an important call, the other side will try again.)

Talking about the batch sending feature, I feel bad for those hardworking HRs getting spammed in this way. But from the last year of job finding experience, I spent a lot of time searching the company and decided I'd like to go there, sending messages and my résumé to them, and got no reply. This happens a lot. So to improve the efficiency, I decided to spam them and see who came back to me. After all you have to reply me before we can keep talking. And HRs are paid to work, while I'm not.

Also, talking about making the phone call, I think for an unknown person, calling them without any beforehand communication is rude. If a friend calls me (which my phone will show his/her name, assuming I have friends), I'm ok with that. We're friends and I'm expecting that. But unknown people? No, thanks. I always text the person and ask if now is a good timing to call him/her before making the call. I hope others can ask before calling me too.

Compared to Java functions, yes, but overall no. According to StackOverflow, each JNI call is several nano seconds more compared to Java function calls. The main overhead is copying data from the Java heap to native memory. But if you use something like native buffer, there should be no such overhead.

If you load a big dataset in Java using a byte array, then you want to pass it to, let's say some BLAS implementation, then good luck copying all those data. But with native buffers, you can just pass the pointer of that buffer to the BLAS implementation and you're good to go.

JNI is still Java oriented, which requires you to write some glue code to translate the difference between C and JVM world. (but with JNI, you can call Java code in C)

Now I'm using JNA, which is a black magic that automatically generates the proxy to call native shared libraries without any additional C code, with the cost of performance.

@sdgathman

But it looks like Jython only supports Python 2? Python 3 is still in the future...

It will be great if Python can be ported to other platforms. The flexibility of Python is great for exploring things like new network structures, etc. But once you have decided most of the specifications, it's better to use something like C or Java to build a more strong code base (so a typo won't screw you up, LOL)

And I have to say, I'm really jealous of Python on machine learning stuff, where JVM is (almost) completely being ignored until people need a more robust way to develop and only find out the Java is a complete nightmare to do operator overloading and have to write something like "a = a.mul(b)"

As a JVM lover, I am jealous of the ability to call C code directly from CPython.

And yes, coroutine is powerful. I'm using kotlin coroutines and it's a huge (free) improvement of Java's native thread.

@freemo co-routines can run on multiple threads, where the "tasks" can yield and the thread from a pool can switch to another "task" without suspension or something. At least kotlin coroutine can, and according to sdgathman, Python can do it too. That's the ultimate free boost you can get by just switching to another tech.

But if Python can do that, then my earlier hypothesis about switching to go will give your free boost is wrong
