General Discussion / How to scan bar code from phone?

« on: October 27, 2019, 04:04:24 pm »

I took a photo copy of this bar code and it won't scan at the register. If you noticed, this is not your typical bar code. Is this some type of new fangled bar code that is protected by encryption.

General Discussion / Should you save your credit card for future purchases?

« on: August 18, 2019, 09:17:45 am »

I personally think it's safer to save credit card data for sites that you shop often. My sister on the other hand says that its safer to not save credit card data and type in your credit card information every time you want to buy something.

From my perspective, it's safer to type in your credit card information once because the more times you type in your credit card information, the more chances a hacker has to steal it. If you type your credit card data 100 times a year, it gives hackers 100 chances to steal your credit card details.

My sisters perspective is, if Amazon ever gets hacked, hackers will get access and steal your credit card information. If you don't store your credit card information for future purchases, then hackers can't steal your credit card information.

Me and my sister were arguing back and forth about this, who is right? I tried searching online to prove that it's better to type in your password 1 time, then multiple times, but came up empty handed. I guess its not something that people think about often.

Can you really be infected just by receiving a text message. I read that if you receive a square text message, it will infect your Iphone and Android devices. How is something like this possible. How is a text message able to run code without the user doing anything.

General Discussion / How do take a scanned image and split it into 4 images?

I would like to make copies of the score sheet, so that I don't have to buy the game again. My friend has been nagging me because he doesn't want me to accidently use all the score sheets. I keep putting it off because I'm not really sure how to do it. He even offered to do it for me; Instead of telling him that I don't know how, I told him I already took care of it. I guess you can say I am embarrassed concidering this is a newbe question. I would like every page to print out 4 score sheets, that way I can just cut them out. I don't have access to a PC, so I am using my Iphone.

General Discussion / Does turning on Iphone restrictions protect you from hackers?

« on: July 27, 2017, 08:25:55 pm »

I already have my Iphone protected with a 12 digit passcode and have it set to wipe everything after 10 failed attempts. I have read that people turn on restrictions so parents can have more perental control over their kids phone; This is why Apple added the restrictions passcode in the first place. I have restrictions turned on hoping that it will stop hackers from hacking my Iphone camera and mic, along with denying changes to what apps can and cannot connect using a celluar network.

General Discussion / Can ram get infected with a rootkit and also survive a reboot?

« on: July 02, 2017, 04:48:42 pm »

I know that when you shut down your computer all ram is lost. If all memory is cleared from ram, how does memory-resident malware work. This type of malware hides in ram and doesn't store any files on the hard drive. This type of malware is very stealthy because it doesn't require any files. If the malware never touches the hard drive, shouln't the malware be gone when you power off your PC. I'm a little confused how this type of malware works. Thanks!
