I know set top boxes connected to a dish receive radio signals from satellite and are decoded, processed and then shown on the tv sets. What i want to know is what will happen when i change channel , will it be send to satellite and then the radio signals contain the data for new channel or else the stream itself contains data for all channels and set top box processes signals to get the requested channel.
I don't think this is the right place for this question, but to answer it, there are no transmissions from your dish back to satellites (with common satellite TV setups). All channels are transmitted simultaneously using a compressed feed, which your set-top box then breaks down, interprets and displays.
Before zapping, you have scanned your TV, i.e. your TV has browsed and stored the different frequencies looking at available channels.
Whenever you select a channel, your TV goes to the right frequency, no extra information is required.
All the available channels are transmitted via a Transport Stream (see DVB and MPEG standards).

I have two traffic related datasets. One contains traffic signs and the other traffic lights.
I want to merge the two datasets and train the model to detect both of them.
Will unlabeled traffic-signs from the traffic-light dataset affect the training process and vice versa?
From what I've read so far YOLO also learns contextual information about the objects and that's why this concern.
As you mentioned and as I found there, "YOLO sees the entire image during training and test time so it implicitly encodes contextual information about classes as well as their appearance", but I see that the meaning is that it considers the direct areas around the labels to add their information to the trained network, thus, you will likely only lose the information from the unlabeled items, but it will not impact the labeled items negatively.

I have a website where I put music, but I do not want anyone downloading it, or it gets harder and just listening online, like YouTube.
Unfortunately, no. It is a bit like trying to prevent someone from recording an on-air broadcast. When you send video data over the internet to someone's player, they can simply store the information being sent to the player unless you obfuscate it and make it so that the player will only work under certain circumstances and will not share the data. This, by definition, is DRM.
What DRM attempts to do is control the reading of the data entirely, so that it can not be copied. This has varying degrees of success and rarely, if ever, works particularly well. It may keep honest people honest, but if you are sending someone data in a way that they can access it, measures to try to stop them from copying it are... difficult. The most advanced systems use special display drivers and encrypt the data right up to the point it is being displayed on the screen (HDCP), that way other software on the computer can't directly pull the information off the frame buffer being prepared for the screen.
There may be some ways you can mildly obfuscate the access to your video, but ultimately, if you send it in the clear, it is trivial for a knowledgeable viewer to store the datastream. If you use DRM, it is substantially harder, but still likely to be able to be worked around by a dedicated attacker.

I want to use the SAS Google Map Generator but I am not sure if I can on proprietary data. I don't want any of the data to be placed anywhere but my own server, even when interacting with Google.
Ideally what I want is to download the map of my choice (state of Wyoming for example) and all of the locations of that area are in a zip file or shape file for me to be able to pin the dataset locations onto, in my own computer. I was reading this.
But it seems a bit confusing to me. Has anyone used it and know that I wouldn't be sending any of my information back to Google?
I've never done this before so I just want to be sure I won't get in trouble for any data leaks.
Thanks!
If you're using the Google Maps API, as it seems you are, then yes, you are sending some information to Google - namely, the center of the map that you're displaying, plus possibly other information depending on what exactly you are displaying.
If you want to do everything client-side, the easiest way is likely to use SAS's built-in map files. This won't display a Google Maps style map, and will give up quite a bit of detail, but it will allow you to display the state borders, counties, and major cities.
You also could use OpenStreetMaps or a similar product, which is locally downloadable more or less as you describe. However, you wouldn't be able to use the Google Maps API; you'd have to do the projecting in SAS still.

I want to set up a honeypot type trap to catch out and secretly record a tech support scam firm that conned my Grandparents out of a lot of money for a non issue on their computer. Like many such scam firms, they occasionally change their web address and phone numbers and are partially based in India.
I was thinking about running Windows 7 inside a virtual machine and using a SOCKS proxy for the VM's internet connection to hide my true Static IP.
I am then planning to make a video about the scammers and put it on YouTube.
The thing is though, I am doubting whether that I can legally record a conversation in a covert manner and then put it on YT. (In UK)
What I really want to know is whether the scammers will be able to get my private license key, or any other identifiable information from the VM when they have control of it? Also does them having the product ID (including them going through Microsoft) put my license/copy of Windows in jeopardy?
I ideally want to bring them to justice and spread the word about them so that they get closed down. In other words, I want to get my own back on them.
Side Note: If this forum is not appropriate for this question, where would be?

they can easily know that you run on a VM. Just with simple command about your hardware. But, I am sure they will not check if it is a honey pot.I dont know how you are planning to record them. I dont believe that you can record something interesting visually.The first step for them is to have a rootkit on your pc. After that is just about command line. There will be nothing good to record visually other that text line in your honey pot software. And You dont know when the attack you will come. Your Vm must be up all the time and the Ip and Mac address the same. Like the others say dont waste your time.No one in history a been put in jail for hacking a honey pot.

I changed my profit amount in a live trading game with firebug but I can't save the amount which I changed.When I buy or sell the stock the profit is going back to the live rate,if there is any way for saving the changed amount ?
Not from Firebug. You are just editing the in-memory DOM of the page.
If you want to make it persist in your browser then you'll need write a browser extension that will modify the page every time you load it.
If you want to make it persist for everyone then you'll need to change the server to send the updated data. This could mean anything from just editing a file on the server to writing some server side code that can accept a request (over HTTP) to change data in a database and then use that data to generate the page each time it is loaded.
