Soldier Forced to Write
Q: If a soldier is forced to write on Shabbat in order to protect lives, is it preferable to write with a pen or computer?
A: With a computer, since writing with a pen or pencil is a Torah prohibition, and writing with a computer in such a situation is a Rabbinic prohibition (see Kishrei Milchamah 3:41).

Removing Tefillin to use the Restroom
Q: If one removes his Tefillin in order to use the restroom, does he recite another blessing when he puts them on again?

Ha-Rav Moshe Feinstein's Opinion Regarding Smoking
Q: I heard that Ha-Rav Moshe Feinstein permits smoking.
A: This is how he ruled when the doctors said that smoking was not dangerous (Reb Moshe's son, Ha-Rav David Feinstein, also said that his father's ruling in Shut Igrot Moshe, Choshen Mishpat 2:76, allowing one to act leniently and smoke was based on the presumptions of that time that the overwhelming majority of those who smoked were not in danger. This is certainly no longer the case. Kovetz La-Torah Ve-Hora'ah 5772 p. 67).
Davening in the Wrong Direction
Q: After I finished Davening, I realized that I was not facing Yerushalayim. Do I have to Daven again?

Q: It is permissible today to name one's son Yishmael? After all, Yishmael, the son of Avraham Avinu, repented (Baba Batra 16a. Rashi on Bereshit 25:9).
