Lack of Agent feedback – Live Chat waiting time

what is your recommended solution for our mobile Customer service mobile app? We have a live chat that caters all the concerns of our customers but the problem is, we just have a limited number of agents available so definitely, some customers need to wait. What do you think is the best solution to inform them that the queue is quite long and they need to wait (in a way that they will not get mad and understand the situation). Thanks!

How do I compensate for lack of minimum shutter speed when in Av mode with the Canon 750D (Rebel T6i)?

I’m fairly new to photography, and I own a Canon Rebel T6i. Besides manual mode I’ve learned about Tv and Av modes, which to be honest I really liked, mainly when I’m shooting on events with changing lighting conditions and I’m find myself too slow to change the settings for every shot. I like the idea of the Av mode very much for event photography, however the last time that I tried I had a huge problem, the shutter speed was too slow (I was using a 24mm f2.8 pancake lens) so when I got home I find out that most pictures were taken at 1/25 sec, even some at 1/60 were blurry, given that I don’t have super steady hands and people were moving.

After some research I found out that some cameras allow you to set a minimum shutter speed when in Av mode. However my camera doesn’t seem to have that option. I would like to set the minimum shutter speed to at least 1/125 (1/200, would be the best for me right now), but I can’t. So I often find myself shooting events at Tv with a shutter speed of 1/125 or 1/200, but the results aren’t ideal since I can’t control the aperture.

What I’ve tried lately to try to compensate for the lack of a minimum shutter speed in Av mode is to set the camera to manual with ISO on auto. This way I can set the minimum shutter speed (but I’m stuck to it, if the lighting conditions improve I could be taking pictures at a higher shutter speed) and I have the control of the aperture, leaving the ISO to balance the exposure. Far from ideal, I would guess, however is there a better way to achieving this with my Rebel T6i?

I know I could just be using full manual, but as a beginner it can get pretty awkward to have people in events posing and waiting for the to find the best exposure in full manual. Is there a better way to do this or should I just embrace full manual.

The Lack of MBR and MAR Notation in Comp. Sys. Arch, Morris Mano

there’s something that confuses me, in Computer System Architecture(Morris Mano), Chapter 5, the book uses a simple microprocessor which has the following instruction cycle:

e.g. LDA Operation:

AR<—PC (T0)

IR<—M[AR] (T1)

PC<—PC+1 (T1)

Decode (T2)

DR<—M[AR] (T3)

AC<—DR (T4)

But the lack of notation MBR and MAR confuses me. In my opinion, it should be like this:

MAR<–PC(T0)

MBR<—M(MAR](T1)

Decode(IR<—MBR)(T2)

MBR<–M(MAR](T3)

AC<—ALU Operation(T4)

What am I doing wrong?
