- Was going to try out some basic computer science classes at my college this semester, but they told me it’s unavailable right now due to covid. Can anybody recommend some online beginner courses that would give me an idea of what a job in IT would be like?
- Variance-Based Clustering
- Artificial Intelligence and Machine Learning Basics for beginners
- How to do Python Programming Practice Effectively?
- List of Best 8 Python Libraries For Machine Learning
- Automating and testing dotfiles with Ansible, Github workflow and orgmode.
- Some guidance in developing a system QA process
- What is a good short term way to make money online with a background in computer science?

- With Boolean simplification would you "simply" an expression INTO a XOR gate or any similar secondary operator?

| Posted: 09 Aug 2020 08:17 AM PDT Using a dataset of 2,619,033 Euclidean 3-vectors, that together comprise 5 statistical spheres, the clustering algorithm took only 16.5 seconds to cluster the dataset into exactly 5 clusters, with absolutely no errors at all, running on an iMac. Code and explanation here: The actual complexity of the algorithm is as follows: Sort the dataset by row values, and let X_min be the minimum element, and X_max be the maximum element. Then take the norm of the difference between adjacent entries, Norm(i) = ||X(i) - X(i+1)||. Let avg be the average over that set of norms. The complexity is O(||X_min - X_max||/avg), i.e., it's independent of the number of vectors. This assumes that all vectorized operations are truly parallel, which is probably not the case for extremely large datasets run on a home computer. However, while I don't know the particulars of the implementation, it is clear, based upon actual performance, that languages such as MATLAB successfully implement vectorized operations in a parallel manner, even on a home computer.

| Some guidance in developing a system QA process Posted: 09 Aug 2020 04:47 PM PDT Hey guys so recently I've been employed at a medium sized IT company (60-70 employees) that mainly deals with servers. I was originally employed to manage parts and assist in production of servers that brought in from dedicated server manufacturers and sent out after we assemble and install our OS's on them. Recently our QA Tester just left the company without notice and the company's decision is to promote me to a QA Tester job because I have a background in compsci (I haven't finished my degree - I'm taking some time off university because I can't travel due to COVID-19). The basic tools they used to QA test are available, but it looks like a bunch of unorganized scripts the previous guy whipped up. Our requirements include checking for bios requirements/bmc, checking for the integrity and validity of the firmware of all the additional parts and cards added, and etc. Most QA Tests are for the hardware. I'm probably going to start within a month or so - and I want to teach myself some basic knowledge within this specific field of interest. Any tips? [link] [comments]  |

| Posted: 09 Aug 2020 10:17 AM PDT when you are simplifying a Boolean expression would you convert part of the expression into their secondary operator equivalents. For example given the expression: X = BD + A'C' + AC Would it be considered standard practice or correct to simplify the A'C' + A*C into (A⊕C)'? I can't seem to find this answer anywhere on the internet. [link] [comments]  |
