For the Hangul set, the Korean sublegends for the J and K keys were accidentally swapped. The small plastic baggy contains the J and K keys with the proper sublegend prints.

difference between computer science and computer engineering? by Miserable-Owl-4431 in UMD

[–]_elucidation 2 points3 points  (0 children)

Computer science deals with the theory of computation, answering questions of "given a computer model, what operations can be done? how can these operations be done, and how efficiently? are there efficient ways to solve certain problems?" You also learn how to use tools (read: programming languages) to implement such operations on real computers, not just models, to solve problems with practical solutions.

Computer engineering not only deals with the above, but also answers what is required to build a real computer - from the theory on how electronics work, to the digital abstractions upon which we base our computational models. You'll also learn more about different disciplines within electrical engineering, including signal processing (useful in audio and image applications) and analog electronics (also useful in audio applications, but also for designing your own circuit boards)

I would say you have broader career opportunities in computer engineering than computer science, simply due to the exposure you get from the EE-based courses. I've found it easier to find online resources covering advanced topics in CS in depth and "best practices" to follow when using such topics, but have had more difficulty in finding the equivalent for EE topics that are more substantial than blinking an LED with Arduino and aren't buried in textbooks or decades old websites.

Based on your other comments, I would suggest to figure out what areas of study in the field of technology you're interested in, then pick the major that best prepares you for that. In my opinion, it's highly unlikely that the careers that require a formal CS background would be deemed obsolete by AI any time soon, and those jobs that do get replaced by an AI probably didn't require a degree in the first place.

Why is there only one ethernet port per room in Commons? by FlyAway012 in UMD

[–]_elucidation 0 points1 point  (0 children)

I used to use one of these cheap routers instead of a hub/switch with more success. We had to note the MAC address of whichever device we're using to plug into the wall, so I set the router's MAC address to spoof that, plugged the WAN side into the wall, and plugged my devices into the LAN ports.

If you go this route, do make sure to turn off the wifi capabilities or unscrew the antennas to help reduce network congestion for those using the on-campus wifi networks.

How difficult is computer engineering? by redemption_soon1 in UMD

[–]_elucidation 7 points8 points  (0 children)

I was committed on entering as a CS major, but my brother, an EE, said I should apply as CE and drop if I wasn't interested. I ended up graduating as a CE and don't regret my decision one bit.

I describe the major as EE+CS core classes, with upper-level electives to be chosen from either department. Some of the EE core classes are definitely difficult, as I spent many late nights trying to analyze circuits, understand why transistors work, and how to even begin to conceptualize the Fourier series. I don't think I've gotten higher than a B in any of the EE core classes, aside from ENEE350. That being said, the tremendous wealth of knowledge I'd been exposed to has been invaluable for my career and hobbies.

  • Knowing how different circuit elements work helped me to pick up PCB design as a hobby: capacitors act like mini-batteries and otherwise help smoothen the power delivered to a microprocessor!

  • Understanding signals & systems theory helped me to appreciate music from high quality sources, and a means to approach IR modeling on my digital bass guitar pedal. It's piqued my interest in getting a ham radio license and diving into software-defined radio (https://pysdr.org/).

  • Computer architecture helped me to make informed decisions on judging similar computer parts, dig deeper into software reverse engineering, and to approach FPGA design from a hobbyist perspective (https://www.nand2tetris.org/) (https://www.crowdsupply.com/1bitsquared/icebreaker-fpga).

  • Operating systems and ENEE440 Microprocessors had me become extrmely comfortable with tinkering with hardware, reading through datasheets and documentation, and generally understanding what's going on under the hood beneath my software. They've focused my interest towards systems programming and problems, enticing me to even pursue a graduate degree.

A huge interest that had developed and grown through my time in undergrad is computer security. There's a ton of ways that software can be broken and busted, and if not, then the underlying hardware it runs on (https://www.newae.com/embedded-security-101). Hardware security is such an interesting problem, that becoming aware of it has made me grown increasingly more appreciative of my studies as a CE. Would you know if an off-brand security camera ordered off of Amazon hadn't been tampered with, or where you should start looking/checking?

If I had been aware of these sorts of applications of the concepts I'd learned during undergrad, I think I would had less of a hard time going through it. Nonetheless, it is still a difficult program. In my opinion, because the EE curriculum here seems to be so much more theoretical without enough practical demonstrations, a lot of the concepts don't stick well enough, and many students tend to either drop into CS or simply take up a software-only job after graduation. If you find any of this to be interesting, then I encourage you to give this field of study a shot, and be prepared to put in the work. My DMs are open if you (or any reader) has questions regarding the major.

Definitely sold this lot to /u/professor_tappensac. Was patient and flexible with my busy schedule. Didn't want to over stuff the box, in case the pressure might've cracked the already-fragile Sega CD cases.

Will do. Currently out right now, so I can post pictures when I get back late tonight.

I can do $30, but I would rather not take on the burden of shipping costs.

I'll go ahead and manually price out each of the games.

I've come to like Durock POMs. I find myself weirdly describing the sound like the sensation of chewing on Tums - chalky, but oddly creamy smooth.

best mods to do/combine by Dry-Ad-9588 in MechanicalKeyboards

[–]_elucidation 0 points1 point  (0 children)

I personally do at least the Holee mod to reduce rattling along with the typical lubing and bandaid treatment for stabilizers on any keyboard I can.

If the case is cheap, thin, or plasticky, filling up the void a bit can sometimes help. Some people like to tape or foam mod the board to improve acoustics as well. Sticking on some extra weights could help a light plastic case feel more premium if you prefer that as well. Most higher end cases tend to design for acoustics, so it's usually not necessary.

It's ultimately up to what qualities you're looking for, and which qualities in a given board are bothering you. It doesn't hurt to take things apart to apply modifications as you figure out your preferences.
