If Visual Basic is supposed to be for beginners, it's surprisingly complicated. It has both value types and reference types and both can be passed either by reference or value, giving four ways of passing parameters compared to Python&

I second this recommendation! I read Horstmann's books recently and they were excellent. He really puts things in context – any time I was thinking "WTF? Why would they do things this way?" he had an explanation coming up (or

To be clear, by "current working directory", I mean the directory returned by os.getcwd(), not the directory where the script is located. This is what I think the problem is: 1. One might want to run utility programs from arbitrar

Does it? As far as I know, it loads modules from the script's directory (which is usually fine), not from the current working directory. $ mkdir bin_dir $ echo 'print("mymod loaded as expected.")' >bin_dir&

I was responding to the parent comment which suggested that Python "should look for a .venv directory in the current working directory". Doing this "only when you actually run python" doesn't help. It would make it

Loading code from the current working directory is not a good idea. It would make it unsafe to run a Python program from any directory that's not completely trusted, e.g. if we imagine "ls" having this feature: [root@loca

What is (or was) the benefit of using ContentProviders compared to accessing the database directly? They seem useful for exchanging data between apps, but I can't figure out what their role is when they're internal to the app (not

Templating is a core concern of a web framework, so a fundamental design flaw in the templating mechanism seems relevant.

The second example from the documentation [1] disagrees. It displays HTTP header values, which are user supplied, without properly encoding them. Also, it's not just about JavaScript. If values aren't properly encoded as HTML, the

The namespaces are URLs, so DNS ensures the domain names are unique globally, the owner of each domain name ensures the paths are unique for that domain, and the author of the XML document ensures the namespace aliases are unique for the sp

Maybe XHTML (with XML namespaces) wasn't such a bad idea after all?

Not a refresh of the same page, but if you perform some action (e.g. adding an item to a shopping card), that would imply a POST request which then (according to the common pattern) redirects to the original page... so then you do lose the

Refreshes can be very fast, and often essentially invisible in modern browsers, when you don't bloat the page unnecessarily, but I think AJAX still has a use for things like the voting button on HN or "add to cart" buttons in

It does sound quite similar. But in addition to the crucial difference of opt-in vs. opt-out there's also an interesting contrast in how it's framed. Debian talks about what you, the user, can do: help out, participate and vote. I

That's what I've heard as well. But a JIT compiler (like the JVM) might not have to be as clever as an AOT compiler, as it can change its optimization decisions later, so perhaps that might have been more feasible?

Aren't scripting languages meant to reduce boilerplate code? Maybe you just need a better API and not an AI?

Hitting the wrong button on a phone is less of a problem that it might appear at first. An up-vote results in an "unvote" link being shown and a down-vote results in an "undown" link instead, so you can confirm that you
