Compared with Java Virtual Machine? Directly run Python code without the need for the operating system
Josh Triplett started his speech on PyCon 2015 with a "Smile": porting Python to free him from operating the system: he and his Intel colleagues asked the interpreter to run on the GRUB boot program, BIOS, or EFI system. Even the rest of the speech has not been missed. He has many interesting things to talk about and many eye-opening demonstrations.

Hibernate 3 has made some improvements and made some obvious shortcomings. For example, the abstract syntax tree is added, but in hibernate 3.0 beta1, it still seems a little immature.

The ast part of the code is provided by Josh. It seems that Gavin is not familiar with grammar analysis and other compil

to give you a sentence: "view and unit test are just two different types of viewmodel consumers" (Josh Smith ). if we regard viewmodel as a producer, both view and unit test have the same status as consumers. unittest has a higher consumption capability than view. or you can simply think that view is just a less recommended test method. therefore, to implement this mode, the unit test on viewmodel is necessary, and this test does not depend on any UI

thread is initialized with instance, which differs from the third and fourth ways (very subtle differences): The third and fourth ways are as long as the Singleton class is loaded, Then instance will be instantiated (without the lazy loading effect), and this is singleton class is loaded, instance not necessarily initialized. Because the Singletonholder class is not actively used, the load Singletonholder class is displayed only if it is displayed by calling the GetInstance method, thus instant

Translator: You might think Java is very simple, the equals implementation of object will be very simple, but the fact is not what you think, after reading this article patiently, you will find that you know so little about Java. If this article is a Java Programmer's entry test, then I don't know how many people will fall into such a trap.

This article describes a technique for rewriting (override) the Equals method. Using this technique, you can still meet the conventions of the Equals method even when the subclass of the entity class adds a new field (field).
In the 8th of the book Effective Java, Josh Bloch The difficulty of meeting the equals contract when subclasses are described as: the most fundamental problem of equivalence in object-oriented languages. Bloch wrote:
