TDD only works in conjunction with thorough peer reviews. Case in point: at my place of work, code and tests written by an intern can go through literally dozens of iterations before the check-in gets authorized, and even the senior engineers are not exempt from peer reviews (recent interns are especially eager to volunteer).

> if doing GPL stuff use the open source license from ExcelsiorJET.

Thanks for mentioning our product, but I have to make a few corrections:

First, the Excelsior JET Runtime license is sadly not GPL-compatible. Also, you cannot use it to target embedded systems, unless you buy Excelsior JET Embedded and pay royalties, though we are currently weighing the option to switch to OpenJDK to eliminate the latter.

Second, the Standard Edition is free even for commercial use (the above limitations apply).

Finally, other editions are available at no cost for use in public non-commercial projects. It does not matter whether the (software part of the) project is open source or not.

See https://www.excelsiorjet.com/free for details.

Problem is, the God Folder dates back to Vista and it is the Windows 10 Creators Update that began setting that field to NULL. Apparently the author of that change did not foresee any backward compatibility issues.

Excelsior guy here.

Overall, I would say that AOT suddenly becoming kosher helps our business way more than competition hurts it.

Then, "JDK9 has AOT out of the box" is a bit of exaggeration. Oracle AOT is only available for Linux/x64 ATM, yields huge binaries and may be a bit cumbersome to use: http://mjg123.github.io/2017/10/04/AppCDS-and-Clojure.html

The main difference however is that a binary produced by Oracle AOT is to a big extent just a pre-populated HotSpot cache, whereas Excelsior JET has been AOT-centric since day one. In practice that means that with Oracle AOT you have to ship both the native binary and the original class files to your customers, and with Excelsior JET you only ship the native binary, which makes reverse engineering your application more difficult.

I recall us being quite surprised when a customer survey had shown that IP protection is more important than application performance for many of our customers, even though it was just a byproduct of our optimization efforts.

Author here. Kindly (suggest where to) cross-post - I think it's important for the health of our industry that freeware authors and open source enthusiasts keep getting rewarded for their efforts. Thank you.

Some info for those that want to AOT Java without paying for it:

The entry-level edition of Excelsior JET is free (as in beer) since the end of August 2016. Licenses for the more senior editions have been available for non-commercial use at no cost for many years.

Low/zero cost is a benefit only if everything else is equal. Eclipse and Netbeans are free, yet people pay for IntelliJ IDEA. We use an expensive commercial GUI testing product because all the free and cheaper alternatives sucked big time, and support was either poor or non-existent.
