Experiment: Deleting a post from the Internet

I hate all the languages. Once, I tried to make my own language, but I couldn't figure out what language to do it in, so I never started.
Most of the time, you don't have any choice of what language to work in. Whatever language I'm using, I've learned to appreciate both its strengths and weaknesses.
The whole java system was designed by an insane person whose answer to everything is to use a Design Pattern. If you see design patterns as a way of working around problems in the language, you will see that Java has many.
On the other hand, the folks at Sun really put the work in to make Java a specification that works on embedded platforms, so we're stuck with it there. I wouldn't really trust Python or C to run my desktop on my phone.
Also, what's with all those folders? I have to use Eclipse, against my will, because it knows how to jump around all those 1000 character path names. Would it really hurt anybody if I kept the 10 objects in my application in the same folder?
If you have enough experience, memory leaks are rare. It's second nature -- malloc/free come in pairs. You can't forget one. It would be like forgetting to flush or turn off the lights. You just do it.
That being said, if you're going to paint a house, you don't want to be using a fine brush. You want huge rollers. If I'm writing a whole application, or a system, I would avoid C if I can.
It is difficult to make large changes to a C program. When I'm working on an algorithm, and I know that the first cut won't be right, often I will code in python first and then translate it into C by hand when it's done.
Javascript lacks a linker, so all the code shares the same namespace, but everyone knows that, so everything still works together.
Coffeescript is nice. When you have to write tonnes of code, coffeescript will make you at least 25% faster. You can see that many more lines on the screen at once.
When you code in coffeescript you have to be very aware of what Javascript is going to be generated. That's the problem. You have to know Javascript first. Anyone new coming to your project has to first learn Javascript, and only then learn coffeescript, and then learn your codebase.
Also, nearly nothing is built in. But if you have to do X, there are always a dozen modules to choose from that do the same thing. Which do you choose? Which will get support if you have problems?
I learned Scala on the job. Yup, a startup was actually using it for their production system, and I joined them fairly late.
This allowed me to see the ugly side of Scala: Type inference. Types are inferred to the extreme. Everything has a type, but figuring out what that type is means checking different files several levels back. And Scala inherits Java's folder insanity, so it means delving into several levels of folders to find the right file to lookup the type.
In short, Scala was great -- for the original developers. Newcomers had a long learning curve to learn the existing code.
Unfortunately it's baroque. Development seems to have stopped at about the time that Berkeley invented sockets. Almost nothing needed in the modern era is included. Why is it so much work to make a simple web service?
It still needs some work in library support. When I want to do X, which library should I use -- the one on github from 2011 or the one from 2013 that is half finished? One is linked to from the official pages, but it the official pages don't seem all that up to date. Sigh, I guess I'll have to write my own...
If you have to do some number crunching or scientific computing you will be well-served by choosing Python.
Strings can be both text and data in python, so you have to learn about text encodings early on.
My knowledge of it has rotted. I think Perl has changed significantly since I learned it in 2000, and I'd have to relearn everything.
I'm surprised it's not on your list.
It's pretty well integrated and matured in Linux, has C-like object-orientated characteristics, easy to learn, has a wide peer reviewed developer base and tons of free modules and libraries to do just about anything..
Yes it's limited being an interpreted language in some ways if you want a language to create OS independent standalone apps that need fancy GUI's.
That said, for many things Perl is extremely fast, convenient and powerful. Particularly when it comes to handling text strings/regex string matching, data processing and internet/Web development.
It's sad many Web developers have abandoned it for PHP which IMO is a very sloppy and limited scripting full of bugs and exploits compared to Perl.
I am a Chinese, so, I can't imagine this...
In fact, I found it quite useful.
