Related Links to Audio Shiurim

I have come across some audio shiurim that relate to issues we've disussed in previous posts. I thought it would be worthwhile pointing them out:

In this post we discussed the issue of having your internet business run on Shabbat. R' Elon Soniker recently gave a series on the topic. I've found 2 parts so far: Part 1   Part 2

[FYI - I found the following summary (in shorthand) of Part 1:  "Websites on Shabbat? Looks at 3 types: 1) informational only (e.g. Shul website); 2) deferred sales (widgets to be delivered in the future); 3) immediate sales (download computer programs). Well, what’s the issue for Shabbat? (Rashi in Beitzah) I) business prohibited under Mmtzoh Cheftzocha; or II) maybe you’ll come to write because of the transaction.
Mishneh Brurah says must be “obvious” that it’s business for internet so: I) wouldn’t be a problem; II) might be. Detailed discussion of time clocks/zilzul issue (but leaves out R’HS unique shitah based on “new” text of Rambam). Another issue – What if ownership action takes place on Friday but on condition that it not take effect until Shabbat day.]

Also on this topic, R' Assaf Bednarsh gives a shiur on these issues here.

We also have been discussing Machon Tzomet's solution to oil drilling on Shabbat. I mentioned R' Rozen's acknowledgement of the controversial nature of his institution's approach and the critique it has received from other halachic authorities.

I was told that R' Dovid Miller discusses this debate here.

Full disclosure - I have not yet listened to any of these shiurim so I cannot comment on the content.
