Comments for Class csc4110

Test post   [Dr_Weeks]   Jan 15, 2019 at 07:55:53
This is a simple system to post questions and comments related to class. If you are enrolled in this class, you can log in with your first name followed by an underscore, then your last initial. Then use your official e-mail address (before the @) as your password. The password will not be displayed. For example, suppose your name is John Doe, and your account name is jdoe4@student.gsu.edu. Then you would log in as "John_D" with a password of "jdoe4".

I am starting my lab01 Assignment and I dont have the battery cord to power my arduino in my package.


Missing Materials   [Corey_T]   Jan 28, 2019 at 23:12:18
I received my the package for my materials on the 24th and the TA told me to come back next week for the rest of my materials to do the lab but the day I am able to go is a snow day


Re: Missing Materials   [Dr_Weeks]   Jan 29, 2019 at 11:40:24
Since we had an unexpected snow day, I'll push the due date to Feb 5.

thanks

@Corey_T power cable   [Dino_C]   Jan 29, 2019 at 19:57:46
You don't need a power cable. You just need a printer cable that will connect your Arduino to your computer. The USB port will provide enough power to power your Arduino.

Lab 1   [Casey_M]   Jan 29, 2019 at 22:50:27
I wanted to know for the first lab if we were supposed to strip the wires to connect on the bread board from this cord we recieved and where we are supposed to get the resistor from.

Re: Lab 1   [Dr_Weeks]   Jan 30, 2019 at 07:59:50
Don't strip any wires. The wires for the temperature sensor should already have the wires stripped about 3 mm (or 1/8 inch) at the end. I don't recall Lab 1 asking you to use that sensor. I'm not sure what other cord you could be talking about. Bring it into class tomorrow and ask.

The resistor should have been with the equipment when you checked it out.

No office hours on March 13   [Dr_Weeks]   Feb 22, 2019 at 08:19:05
I will not have office hours on March 13. Please come see me the week before if you need to see me.

Video Length   [Dino_C]   Mar 4, 2019 at 07:40:30
I noticed that the video can be about 5 minutes in length. How much longer can it be? 30 seconds? 1 minute?

Re: Video Length   [Dr_Weeks]   Mar 5, 2019 at 08:14:21
The exact length is not really the issue, it's whether the content is flowing and engaging at a good pace. If you need to have time limits, I think 30 seconds before or after 5 minutes is acceptable, IFF we are not aware of the time. That is, if someone has a presentation that lasts 5 minutes and 0 seconds, but the pace is so slow that the class is convinced that the elapsed time cannot possibly be correct, then full points should not be given. On the other hand, if we are so engaged that it lasts (say) 5 minutes and 45 seconds, but feels like we just got started, I don't think that is a problem.

Temperature Sensor   [Dino_C]   Mar 5, 2019 at 10:53:27
Is there any way that the Lab can be pushed back till next Tuesday. I noticed last night that I never received a temperature sensor.

RE: Temperature Sensor   [Dino_C]   Mar 5, 2019 at 10:59:15
Never mind...my mind's scrambled. I thought tomorrow was the 7th. I'll just pick it up tomorrow from the Lab.

lab#2 grade   [Rodrigous_W]   Mar 7, 2019 at 15:37:08
Hey professor weeks, I emailed the T.A.and he stated that he gave you my paper and that he added my demo grade to the paper.

hash functions   [Flaviu_T]   Mar 26, 2019 at 13:05:19
you mention using "standard cryptographic hash function", but these algorithms are fast & should never be used for passwords.

There's password specific hashing functions listed at https://crackstation.net/hashing-security.htm, "To Store a Password", which are specifically designed to be slow to compute.

Re: hash functions   [Dr_Weeks]   Mar 28, 2019 at 07:42:02
Use a standard function, not one that you write on your own. You are supposed to follow the instructions on the web-site given in the lab, which is the same one that you mention. Are you saying that those instructions are contradictory? If so, we can discuss this in class.

quiz#4   [Rodrigous_W]   Apr 12, 2019 at 02:25:26
hey professor weeks which chapters will be on quiz #4

Re: quiz#4   [Dr_Weeks]   Apr 12, 2019 at 07:35:30
Everything from the last quiz to what we covered yesterday. We were close to the end of chapter 4 last time, and chapters 5 and 7 are short, so we've covered part of 4, then 5 to 7.

Re: quiz#4   [Dr_Weeks]   Apr 13, 2019 at 17:18:44
To be clear "5 to 7" certainly includes chapter 6, which we discussed in a couple of classes.
