Can somebody please help me answer these three questions?:

Two identified here:

When we multiply the immediate operand by 4, do we multiply the binary or the decimal by 2^2? Is the addition sign for concatenation?

What is the maximum offset from $s?:


Thank you in advance!


Question: How to find a co-working space in Lille as a tourist?
Answer: From the website of La Cantine in Paris, I found a map of coworking places in France. There happen to be at least 2 having a website in Lille. Both have an open space and coffee room with at least one meeting room.

La Coroutine has offers for short stay, 2 euros per hour up to 10 euros per day.

Co-factory only targets regular coming people apparently, starting at 49 euros for 4 days, but they offer a one-day trial if you email them.

Otherwise, you still have the city public libraries.
