    Well, I try to understand why something is included. I’ve run arch for years (BTW), though my current computers are running Fedora and Debian. I won’t say I know everything about Linux or even installing it or booting it, but I do know more than I would if I just followed step by step.

    NEVER run a command you don’t know the purpose of. That being said, “sfc” stands for “System File Checker.” It is a utility that can help restore corrupted windows files. sfc /scannow checks your protected files and restores corrupted files from a local cache. The process can take some time and you MUST let it finish it’s entirely.

    In conclusion, this command is generally safe to run.






  • A microphone is a membrane attached to a means to generate electricity (like shaking wires around a magnet). When you make sound by a mic you shake the membrane and it in turn generates a small amount of electricity.

    This electricity is an analog signal (it’s continuous, and the exact amount changes over time). We can take that signal and digitize it (literally chop it up into distinct digits) by using an ADC or analog to digital converter. Essentially an ADC takes a snapshot of the analog signal at a specific point in time, and repeats that snapshot process very quickly. If you take enough snapshots fast enough you can have a reasonable approximation of the original signal (like following a dotted line).

    Now we have a digital signal and we can store those series of snapshots in a file.

    But how do we turn that back into sound? We literally just follow the process in reverse.

    We open the file and get the list of snapshots. We pass those to a DAC or digital to analog converter that generates a continuous analog signal that passes through every original point. We pass that signal to thin wire wrapped around a magnet and attached to a membrane. This mechanism takes the small generated electric field from the DAC and causes the membrane to shake in the same pattern that the mic originally shook in.

    In practice there are often other steps in line such as amps to increase the strength of a signal or compression to minimize how much space the snapshots take up.









  • Sanctum 2 is a bit older, but it holds up as a solid FPS tower defense hybrid. It’s often on sale for around $4. The dlc is also well worth it, doubling the base game content.

  • Proficiency is absolutely key. I was troubleshooting a feature with a Jr the other day and asked him to search through the log out put (that was currently being displayed on his terminal). Unfortunately he was trying out a new emulator and didn’t know how to actually search the output.

    We went about it a different way, but at the end I just told him it didn’t matter what tools he used as long as he actually knew how to do what’s required with them and to please get that figured out for next time.
