As you know "bilirim" and "haber veririm" is present tense but using them in sentences include "gelecek hafta" and "sonra" give them a future tense meaning. So the translation is correct. But it would be better if you used "öğrenirim" instead of "bilirim"

 Interesting.

 Beyaz Türk means elite Turk. It is some kind of an sarcastic sentence.

birilerini hep ozluyorumda, bu baska hani olurya icin bi tuhafrtir bilemezsin kendinle ne yapacagini iste oyle bisey galiba

I miss some people, but that´s something different, sometimes (it happens, isn´t it? that) your soul ("your-interior") is so odd (funny/amusing ?). You can´t know what you will do with yourself. And it seems it is something like that.

In my opinion it is a very good translation.

Let me explain more. "Hani olur ya" is some kind of an idiom that people prefer when they want to speak poetically. It means something like "sometimes it happens right?"  Ex:

Hani olur ya birden gülümser insan.

You can translate this sentence differently:

1) Sometimes it happens right? All of a sudden people smile.

2)Sometimes all of a sudden people smile right?

But generally if you use if (-se, -sa) after "hani olur ya" you can translate it as just in case. Ex:

1) Hani olur ya gelmezse, kafana takma.

Just in case if he doesn´t come, dont mind.

2) Hani olur ya gelirse beni ara.

Just in case if he comes call me.

This online dictionary tricked me I would also use straight.

 Nope I changed my mind. Let me explain it.

birilerini hep ozluyorumda, bu baska hani olur ya icin bi tuhaftir bilemezsin kendinle ne yapacagini iste oyle bisey galiba

Here "hani olur ya" means something like " sometimes". "So it happens right" is also more proper than "just in case" But use sometimes here.

But here in this sentence just in case is more proper.

Hani olur ya gelmezse beni ara.

Just in case if he doesn´t come call me.

You should decide the correct expression looking at the context of the sentence.

Two hints:

1)Sometimes -de, -da means "but". Ex:

Ben geliyorum da o gelmiyor.

I come but she doesn´t come.

2) sometimes ya means right as a question. Ex:

Bazen konuşamazsın ya normaldir.

Sometimes you can´t talk right? It is normal
