  • Using RAID 1 as backup?

    I understand what RAID 1 is (disk mirroring) - you drop a file and it gets mirrored to the other drive. If one drive fails, your data remains. I understand.

    I am planning to use two external HDD as RAID 1 for back-up. However, people on blogs are saying you still need to make a backup of your RAID! I am confused. In that case, aren't you just manually mirroring your data to a third drive? Why do I still need to back-up my RAID?

  • Masters Degree vs CompTIA/CCNA/Etc.?

    I have a bachelors degree in business administration and have been working in a financial role for 8 years. However, I hate my job and love programming and technology. Cybersecurity is the field that interests me the most but I also like software engineering, web programming, etc.

    I am looking for a career shift. I was thinking about a masters degree in computer science since I have taken 6 computer science courses as electives in my undergraduate. However, the other side of me is saying not to waste money on a masters as there are certificates available. I have done the CompTIA A+ and currently studying for the Network+. Other certificates I will be doing next are Security+, PenTest+ and CCNA Security.

    Do I need the masters or are the CompTIA (A+, Network+, Security+ and PenTest+) and CCNA Security Certificates enough? I know how to program in C++ and python. I also know HTML, JavaScript, SQL and PHP (self taught)

  • Do I need a masters degree in computer science for a career shift?

    I graduated with a bachelors degree in business administration and worked as an auditor/banker for the past 8 years. I hate my job and always loved to code. Wanted to study computer science but got forced into business.

    Anyways, I lost my job during the COVID situation and I did the following undergraduate courses online: Programming I + II, discrete math, data structures and algorithms, networks, operating systems and software engineer.

    I want to ask if I need a masters in computer science for a career switch or can I just do certificates like CompTIA and CCNA? I already did CompTIA A+, Network+ and security+ Going to do Cloud+, PenTest+ and CCNA Security later on.

    Is a masters worth it or just wasting money?

  • Is being a college professor worth it?

    I would love to pursue a PhD in Human Biology to teach at a university or college. However, I'm not sure if this is a good choice as I heard academia does not pay off well. As a professor, can I just teach or do I have to do research as well?

  • How is a thesis done for a PhD in Biochemistry, CHemistry, Biology, Biomedical Science?

    I understand in the business and social science, you read papers, analyze data in your thesis. However, how does it work for a PhD student in the science fields, such as Biochemistry, Chemistry, Biology, Biomedical Science? Are they required to just do research and data analysis? Or are they required to use experiments to come up with something new?

  • How much biology is needed for Bioinformatics?

    I heard from a lot of people in the field that micro biology, cell biology and genetics is all you need for bioinformatics. Yet, I dont understand why some universities require a lot of prerequisite in biology for their masters in bioinformatics?

  • which is a better career choice? Software Engineering or Chemistry?

    I am in a bit of a roller coaster here and I understand those are two different path. Let me explain myself more as I love both software engineering and chemistry.

    I enjoy the lab work in school. I enjoy working with chemicals. My main interests are Biochemistry and Organic Chemistry.

    I also love programming. I did some programming and basic software and website programming projects. I really enjoy it. Another thing I enjoy in IT is cyber forensics.

    I enjoy both almost the same but I want to ask which is a better career choice. Again I love both and doing both is not possible. I feel software engineer is a better choice as Chemistry is not a good career (from what I heard).

    What are your thoughts?

  • Is bioinformatics limited to only genetics?

    I did some research and all i can find on bioinformatics is application to genes. Is bioinformatics only limited to genetics or is it applicable to environmental science and other fields in biology? How often is it used in other fields?

  • I don't have any friends. Is there still chance of marriage?

    I am 30 yo Male and i don't have any friends at all. I am a loner. I don't like spending time alone though. I cant make friends as guys don't enjoy my presents. However, girls are somehow okay with me. I only dated two girls in my life and it didn't go well. I am always at home but love to go out but no friends.

    My mom found a wife for me and i do want to get married. I am financially stable and know what i want in life and willing to settle. The problem is because i dont have any friends and because most of the time i spend it at home, im worried that she won't accept me. I am also thinking who can i invite to my wedding. Is there a chance for loner guys like me. Has anyone had a similar experience?

  • Passing the GRE chemistry test and applying for a masters degree in chemistry?

    I did my bachelors degree in business. However, i wanted to study chemistry. I won't go into details why.

    I am currently doing an online diploma in chemical engineer while taking courses in general chemistry, physical chemistry, organic chemistry and analytical chemistry. I am working at the same time but not in chemistry.

    I don't like the business job and i am planning to switch to science. I also want to add i love chemistry and i was a straight A student back in high school.

    Question is, if i get the diploma in chemical engineer and passed the GRE chemistry exam, what are my chances of being accepted in the masters in chemistry program?

  • Should I buy a new Limited Jeep Compass or a used 2017 Jeep Grand Cherokee (both almost have the same price)?

    I am interested in the new Jeep Compass. It costs around $25,000/- where I live. The compass is a fun drive. Only problem is the slow engine, which I don t mind.

    However, I also found a used 2017 Jeep Grand Cherokee for almost the same price and has 30,000 KM on it. I love the grand cherokee. It has a lot of space and engine is great. To be honest, I don t need that much power in the engine but I love it. My only problem is that it is used and not safe. The new compass is rated "Top Safety Pick" by the IIHS.

    I will be getting married soon. I feel like i will be needing extra room for the baby stroller and other shoppings/groceries. The compass does not provide that room. I have a 2014 jeep compass and I understand.

  • does boiling cold cuts in water remove salt from them?

    I read that if you boil eat in water, the salt will be removed. I am wondering if the same works with cold cuts (or deli meats, or whatever you call them)?

    I tried it and I felt the salt reduce significantly

  • Is resistant cycling machine and squats enough to train legs?

    I use to train Push/Pull/Lower body. But now I went back to Jujitsu and I train jujitsu three times a week.

    I find it difficult to balance work-family-study and training for 6 times a week.

    I am thinking about doing the regular push/pull routine but also twice a week on BJJ days a leg workout where I do the following

    - Cycling machine for 10 min (on high level for resistance)

    - Squats (5 x 5)

    Will this be enough to workout legs. I read that cycling works out the abs and entire legs. I'm planning to do legs when I finish BJJ training.

    My plan:


    SUN - BJJ + LEGS + ABS


    TUE - BJJ

    WED - BJJ + LEGS + ABS

    THU - REST

    FRI - REST (Jogging 30 min in the morning)

    THU is more of a family day and FRI is more of a friend's day.

    Where I live there is no work on Friday and Saturday
