Using computer software codes that have Greek names

Q: I'm a computer scientist and in my learning and use, there are often libraries of codes which are very popular and heavily used. They often contain a lot of math or pre built software. The problem is that the library sometimes might have a haram name like jupyter, greek mythology names much like the names of several planets. What should a Muslim to do in this situation?

Is it a requirement to go to a musjid to accept Islam?

Q: I recently was asked by a non Muslim if I can tell him the shahada to make him become Muslim because he wanted to become Muslim. So I told him the shahada in Arabic and also in English and explained what is Islam and what you should believe in to be a Muslim. He did it and he believed on what we all Muslims believe so he became Muslim.

After some time this guy asked me that someone told him that the shahada you believe and the things you believe in that the other guy told you. With that you can’t become Muslim because everything he told you is true but you must go to a masjid and repeat it with the masjid Imam so he can repeat with you then you will become Muslim. The other guy took him to a masjid and the imam repeated the same things.

My question is that is this guy became Muslim the first time I repeat the shahada with him or no he became Muslim when he met the masjid imam which one is truth  Can someone regular not an imam make someone become Muslim ? Or no only imam can make someone Muslim ? Am I sinful because I told him shahada first time and he believed it?

Books regarding Seerat of Nabi (sallallahu alaihi wasallam) and Sahaabah (radhiyallahu anhum)

Q: Somehow, I got interested in reading other books related to Islamic History besides reading my Daily Quran and Hadeeth. I got know about Khilafat O Malokiyat by Molana Modudi Sb., and I read that book. It was a very nice book. Somebody recommended reading "Al Raheeq ul Maktoom". I have read it too. Again, it was a realy nice book.

I want to read some more authentic books on Seerat of our Nabi (sallallahu alaihi wasallam), and Sahaba Kiram (radhiyallahu anhum), and Umahatul Momineen, and also Islamic History, which are being linked to Quran and Hadees. Could you please recomend me some books (names of books with author)?

Exerting oneself in ibaadat

Q: I have a question about the Sahabi who only did the bare minimum and didn't do too many optional acts. When another Sahabi stayed at his house for 3 days he didn't notice anything special that he was doing. Despite this, Rasulullah (sallallahu alaihi wasallam) said he was a jannati. Other Sahaba always followed the azeemat and took the more difficult path. So, as a general rule, should I take the easy path or the hard path when I have to make a decision?
