I think English is not the author's first language; it shows up in the article and in his posts here. We tend to be understanding of poor grammar here, but the instinctive reaction to flawed English is that the message is also flawed. While it is possible to work out what the author meant, it takes some consideration - that consideration is better spent on the ideas.
Writing should be like a window, that you can see clearly through - not one you have to keep checking to see if it's a mark on the window or what you're supposed to be seeing. Excellent writing disappears.
So, TalkBinary, if you're genuinely interested in writing, improving your English is crucial. It might seem prejudiced to criticize your English, but it is the first thing people see about your writing, and because their time is limited, they will judge it on that basis. swombat has given a lot of his time to you - although it can be harsh to hear negative comments, this is valuable advice you have received. It might also seem that grammar and spelling etc are secondary, and shouldn't matter (I used to feel this), but they really do - if you want to communicate. Hell, even when I read my own writing months later, any spelling errors etc are very distracting, and if I haven't been clear it is hard for even me, the author, to understand.
I'm not sure of the best way for you to improve, but the first thing is for you to want to. The second thing is to get feedback - swombat has given you a start (and I agree with all his writing points). If you can handle it, seek out further feedback and criticism. If you are in school/uni, you can probably find someone there to help also. The third thing is to take action on it - such as rewriting this article with the errors corrected.
Finally, I wanted to fill out one of swombat's points: writing out an algorithm can be crucial. I just spent the last two months getting one clear (I did have a go at coding it directly earlier on, but it wasn't clear enough). Once I was clear, it just took a day (today) to design, code and debug. Now, this is unusual; I'm doing research on relationships between grammars for a startup. Mostly it's not needed, as swombat says. But after two months, I just wanted to speak up for one of those problems that is not in the "most" category (though I'm inclined to think that all problems are trivially easy once you know how to solve them; similar to how mathematician can only do "trivial" proofs.)
I actually think the ideas quoted above are actually good ones, if you're not clear on what you're doing (though annoyingly expressed). Exploratory programming is also helpful. I find it's a mix; it depends how complex the problem is, how many different issues there are - and crucially - how much experience you have with that kind of program. Familiar problems are easy to solve in your head or at the keyboard. I used to always work that way, until I got into grammar stuff.
BTW: if you purely compiled this, so it's not your writing, remember that as editor, it's even more important that you are able to write well, so as to improve - edit - the writing of others. Anyway, good luck, I think the article is hepful overall, good on you for actually doing something and having a go, and I hope you start to take this opportunity, of room for improvement.
