The IP address for Tim's high school girl friend that has supposedly hacked into the DOD, 192,168.8.8, is a Local Area Network address. It would not be visible outside of the local area (i.e. home, school) network. The IP address visible would be the IP address of the Wide Area Network connection, for example, the cable modem attached to the Internet.
Tim's 1994 exploit states "Serving [...] on 0.0.0.0 port 3030". The address 0.0.0.0 is reserved and is not allocated to any machine.
Torres says you can't put pens on an expense report. Pens and other office supplies can absolutely be put on an expense report.
When McGee is working on his old computer, he asks Delilah for a Torx screwdriver. She holds it up, and Tim pretends to take it but you can clearly see Delilah put it back down before Tim continues to work on the computer. Delilah actually holds up two Torx screwdrivers of two sizes, one in each hand, and Tim takes one and Delilah puts the other back down. It's not obvious because one of her hands is right at the bottom of frame.
In the 'First WWW access' scene with his girlfriend, Tim is typing lines of code and calling python files. Python is a programming language that did not exist at that time.
When Kasie wheels McGee's old PC into autopsy, she says it's connected to the internet. While it's possible to power the PC on a trolley using a battery and inverter, the operating system would be too old to be compatible with any Wi-fi hardware.
There is no way that McGee (1994) could cause an electricity overload by running a script on the phone company's server.
The high-school McGee says "the baud rate's only 8k, but at 7bps..." and his girlfriend finishes "you can have up to 56 kilobytes per second". Both of these statements are wrong. What McGee meant was 7 bits per baud. His girlfriend means 56 (7 x 8) kilobits per second, not kilobytes (and since there are 8 bits per byte, 56 kilobits per second would be 7 kilobytes per second in this case).
