      From my perspective, this video is absolutely great for anyone who’s taken around 2 semesters of CS classes (me lol), as it summarizes almost every concept I’ve learned or heard about until now. For someone who has no idea about IT (me 2 years before), this could be a great introduction, but some concepts might fly over their heads. Nonetheless, this video is definitely the best short format information video amongst others from what I’ve seen. Kudos to the creator

      There isn't a specific code, but rather a combination of factors that law enforcement and criminologists use to profile and identify serial killers. These include:
      1. Behavioral patterns:
      - Modus Operandi (MO)
      - Signature behaviors
      - Ritualistic actions
      2. Demographic characteristics:
      - Age, gender, race
      - Socioeconomic status
      - Education level
      3. Psychological traits:
      - Personality disorders (e.g., psychopathy, narcissism)
      - Mental health issues (e.g., depression, anxiety)
      - Cognitive distortions
      4. Crime scene indicators:
      - Type of crime (e.g., homicide, arson)
      - Location and geography
      - Victimology (victim characteristics)
      5. Investigative psychology:
      - Criminal profiling
      - Behavioral analysis
      - Investigative psychology models (e.g., Crime Scene Assessment Model)
      Some specific codes and tools used in profiling serial killers include:
      1. The Macdonald Triad: a set of three childhood behaviors (animal cruelty, bedwetting, and firesetting) that may indicate potential for violent behavior.
      2. The Psychopathy Checklist (PCL): a tool used to assess psychopathic traits.
      3. The FBI's Crime Classification Manual: a system for categorizing crimes and identifying patterns.
      Keep in mind that profiling serial killers is a complex task that requires extensive training, expertise, and collaboration between law enforcement, criminologists, and mental health professionals.

      ​​​​@@idkmyname2197this is a very surface level video. Think about the iceberg people always use where the tip is above water. Now when applying those things practically, the fun starts. Sounds easy. Looks easy. Not so easy though, and most problems are very situational
      You can read and watch videos about cs "stuff", but if you don't do cs "stuff" you will be very surprised at how cryptic and complex these simple topics quickly become. Everything is just so specific, like in coding you have to say EVERYTHING you want the program to do so literally and logically. Missing one semicolon? Program won't function correctly. I wonder how many lines of code are out there missing semicolon? Lol. Like imagine you wrote a program with thousands of lines of code and it won't work because of a small syntax error, or god forbid a logic error that forces you to rewrite half your code, or maybe in this situation for whatever reason it is a syntax error, but instead of throwing an error to you, it's just causing the program to behave incorrectly. You have to sift through this program. You'd think something like that could be automated and while it probably can, your scenerio may be so specific that the automation would need to be modified by you to fit your situation (you don't actually know what situation you are in, remember? You don't know what syntax error or whatever is causing an issue, but you have to test to find it), anyway instead of modifying it at that point you'd be better off manually finding the error. Anyway basically what we do all day is create errors and then try to fix them. As a software developer it's like 50 percent meetings, 5 percent coding and 1000 percent debugging 😂

      ​@@idkmyname2197 in the video he goes over finding the shortest path like google maps. Sounds easy right? He talks about algorithms, which is a set of instructions. In my course we had to implement an algorithm to actually find a short path between 2 places. It's impossible currently to actually find "the shortest path" for anything sizeable because the algorithm would have big O(n!) which is insanely big. For 25 destinations, you have 15511210043330985984000000 paths to check. That course took me about 6 weeks. Covering intro to Python, then algorithms (including heuristics which gives approximate solutions), then big o, then the task. Every topic he glosses over can be expanded similarly for many other courses. Try making your own linked list and then reordering it, try to use your linked list to make a queue, then try it with a stack. It goes on and on.

    I took my computer science degree years ago and have been an engineer since. My partner has always shown a vague interest in understanding how computers work but gets easily put off. We taught her a little by playing games like 7 Billion Humans and Turing Complete, but eventually it gets too much. Some minor lightbulb trivia for her that she gets interested in, such as the on/off switch on appliances is just binary 1/0, or sometimes the 1 is intersecting the 0 when it is a single button. Things like that.

    I’m so happy I found this video. I’ve been thinking of doing Computer Science at my local University. It’s 3 years, so it’s a long commitment and I wanted to know what the heck I’d be getting myself into. This has given me a great idea - thank you!
    Just for reference, what are some of the main paths you personally know you can take after learning Computer Science.

    0:12 - Yeah that's not just silicon, It's doped with other substances to make it act like an semi-conductor.
    1:46 - A kernel is different from operating system, an OS is built on top of kernel, Window's Kernel is "Windows NT Kernel" and Linux is infact a kernel and OSes built on top of Linux are called Linux Distributions or Linux in short, and Mac's Kernel is "XNU" or "X is Not Unix".
    2:42 - Also 2GHz doesn't mean a CPU would execute 2 Billion instructions per second, that is because ALOT of instructions take more than 1 clock cycle to execute a instruction.
    4:42 - Not only static typing avoids bugs, but It MASSIVELY improves performance because in dynamically typed languages there's a always a overhead of keeping track of the type of variable and it's size.
    4:54 - Also This "chunk" of memory is of known size, on a 64 bit machine a pointer is 64 bytes, on a 32 bit machine a pointer is 32 bytes, that's why a 32 bit machine can only work with upto ~4GB of RAM because the maximum size of address the CPU can work with is 2^32 or 4,29,49,67,296.
    5:07 - Also stack is fixed size which makes it faster to access, but if you need chunk of memory you know size of at runtime, you have to use "heap", but just know that heap and stack both exist in RAM, it's just that stack is faster due to it's fixed size.
    5:21 - A memory leak can't slow down a process BUT it can crash because you will run out of RAM if you keep leaking the memory. ALSO If your program exits, all the memory is just reclaimed by the kernel, so memory leak is just an issue for a process's lifetime, not after it.
    6:14 - You can always resize the array to fit the elements thus not wasting memory, but using Linked list to solve this "issue" is an even worse solution because linked-lists use much more memory than an usual array and are slower to access.
    8:55 - At the machine code level, when you call a function you jump to it but then you have no clue where you have to go after the function completes, so the call stack just holds the address to return to after the function finishes.
    9:11 - Here, '!=' is an equality operator called "not equals to", a not operator is a single exclamation mark and it only _operates_ on a single value.
    Great Video Overall, Perfect for beginners.

      you might start with programming. Although it might sound a bit too much to start, you will quickly learn the programming thinking and you will automatically start to understand how things work. When you don't know how something works, you can search and slowly you'll be learning everything related.
      I don't recommend languages like C or C++ because you might get stuck on irrelevant things like syntax. Instead I recommend some easier languages like python, although python might be too simplified to have a good understanding of programming. Maybe a good language to start with could be javascript, and you would also have knowledge to start building websites in the future if you like that.

    This touches nearly every field in computer science. Except cryptography and operating system development and scheduling. It did not cover hardware development and microchip programming (like VHDL), but since it touched on logic gates and gatter I let it count. I do like the definition of machine learning though. That was elegant. Very well done.

It was great.
