I made my own translation, there were a couple parts that i'm not sure if you understood or not, hopefully this clears that up. If you've got any questions, please let me know.

_____________________________________

Qué bien que en mis pupilas siga entrando luz del sol //How good that my eyes follow the light of the sun
Qué bien que en mi cerebro se produzcan intercambios de información //How good that my brain produces exchanges of information
Qué bien que te pusiste en medio. //How good that you got in the way

------

It's wonderful that sunlight continues to fill my pupils, it's wonderful that exchanges of information are taking place in my brain, it's wonderful that you stepped in the way.

_____________________________________

Qué bien que con mis dedos note frío y tu calor //How good that, with my fingers, i feel cold and your warmth
Qué bien que por mis nervios corran impulsos que me cuentan que estás en mi habitación //How good that by my nerves, run impulses which make me notice you in my room
Que no te has ido y que te tengo cerca. //that you haven't left and I have you near.

------

It's wonderful that i can feel the cold and your warmth with my fingers, it's wonderful that impulses run through my nerves telling me you're in my room, that you haven't left and that you're nearby.

_____________________________________

No sería lo mismo imaginarte //It wouldn't be the same to imagine you
que poder estudiarte con detalle. //That I could study your with detail
Usaré cada segundo que pase //I would use every second that passes
para poner a prueba nuestras capacidades corporales. //to put to test our bodily capacities

------

Imagining you wouldn't be the same as being able to study your every detail (con detalle = in detail). I'll use every second that passes to put our bodily capacities to the test.

_____________________________________
Sólo quedará sin probar un sentido; // I would only stay without testing a feeling
el del ridículo por sentirnos libres y vivos. //the ridicule of feeling alive and free

------

There will only be one feeling we won't experience, and that's the embarassment (ridicule) of feeling free and alive.

_____________________________________

Y qué genial, //and how great
qué astuto, // how crafty
qué indecente, //how indecente
qué maravillosamente oportuno. //How wonderfully appropriate
El soplo de viento //the breathe of wind
que aún hizo atrevido //that i'm yet to dare
tu olor con el mío. //your smell con mine

------

And how great, how sly, how indecent, how marvellously opportune, that gust of wind which made risqué (the mixture of) your smell together with mine.

_____________________________________

Y qué manera de perder las formas //and what a way to lose your way
y qué forma de perder las maneras. //as above - play on words
Ya nada importa, //Now nothing matters
el mundo ya se acaba no quedará nada. //the world would now just be nothing
Disfrutemos de la última cena. //We enjoy the final dinner

------

And what way of losing the forms, and what form of losing the ways. Nothing matters anymore, the world is coming to an end and there won't be anything left. Let's enjoy the final dinner.

Heisenberg's corrections were good, i just wanted to add a couple things:

My first job

Today,is Sunday.
Today is Sunday. [no comma]

I don't need to work, [this sentence is fine, but i would connect it to the previous sentence: Today is Sunday, so I don't need to work.]

I have started to work for a new job about ten days as a Software Engineer,Although I'm not graduate from my college.
I have started (to work/working) for a new job about ten days ago as a Software Engineer, although I haven't graduate from my college. [if you say when something happens, you'll use the simple past (i started, not have started). If you left out "about ten days ago", then you could use the present perfect (have started) to emphasize that it was recent or that it's new information.]

there is one day to rest for every week.
There is one day off every week. [i would say "I have one day off a week"]

This is my first job,But it reallly is a challenge for me.
This is my first job, and it really is a challenge for me. [it makes sense that you first job would be a challenge, so use "and"]

I entered into a new enverionment, it's different from school, many things are needed to learn,I feel so strange.
I entered into a new environment, it's different from school. There are many things i need to learn. I feel so strange. [at least in the US, we don't say "many" very much, we generally use "a lot of" or "lots of": There are a lot of/lots of things i need to learn.]

But I hope I could do it by my best.
But I hope I can do my best. [i think this sentence would make more sense as: "I feel so strange [previous sentence], but I will do my best"]

Good luck at your new job, don't let them take advantage of you just because you're new and this is your first job. They still need to respect you! 加油！

我也觉得有点不礼貌，但你可能没有那个经历：每次我登录会收到十多个“Follower Requests”。学习汉语，会讲英语的人中间大概有人会觉得那么多人每天请你的QQ号码或者Skype帐号很麻烦的。我个人觉得自己很幸亏，有很多人都要学习我的母语，这样找到一个“Language Partner”很容易，总有不少人愿意帮助我，回答我的问题，什么的。我觉得文章的作者并不是想要“伤人”，而是想简直地说“我会帮助你，但我没有（也不要）Skype和QQ，请大家别问”。语气可能不太友好，但winsonwcp的话有道理，我们是学习汉语的，汉语不是我们的母语，而且我们的文化和中国的很不一样。用一个外语来表达你的意思总是很难的，理解另外一个文化就更难。

如果我是你，我就把这篇文章忘了，不理它了。
