Question: What are your thoughts on Valgrind? Especially with bug hunting? Personally I find it to be quite useful for my use cases. You?

Yes it is great! Only problem is with very large projects/test cases it can be very slow. but very valuable regardless! Comment...

Question: Hi, Justin, this free simple vu meter I have linked below uses little resources in reaper and I love how it works. However, I have been struggling to use ai to edit the code to display the maximum VU readout for Left and Right channels and hold the values indefinitely. Can you help me display the max vu readouts (not max sample peaks) and hold them indefinitely even when playback stops? redacted

yeah there was a pretty good flail there, too bad. Comment...

Question: Can you arrange these computer related things in descending order? Means the topic which you know the most, is in leftmost side, whereas the topic which you know the least, is in rightmost side. Topics are : DBMS, Software Engineering, Computer Networks, Operating Systems, Data Structures & Algorithms, C++ (lol), Python, Java, HTML, CSS, Javascript, AI & ML, Cybersecurity, REAPER (again lol), SQL, Word, Excel, Powerpoint. I think these are enough for now XD

DBMS - uh I can apt-get install mysql and create some databases, tweak caching/memory parameters, etc, but I would have to go do a lot of reading to do something like replication or big scaling
Software Engineering - what does that even mean anyway?
Computer Networks - I can set up LANs and such and configure linux packet filters and dhcp servers or whatever, but if you wanted me to change some BGP configuration of a network I would have a lot of reading to do
Operating Systems - not sure what this would mean, exactly.
Data Structures & Algorithms - I can write you some linked lists and binary trees that with enough testing might prove to be without obvious bugs
C++ - mostly use C++11 or earlier syntax, avoid STL so if you ask me questions about STL use I'd have to look it up
Python - bleh I avoid writing it, but I know that it traditionally has a global lock which makes it suck. I've also had to deal with integrating Python with REAPER and I don't enjoy it.
Java - only used it occasionally, in the 90s I wrote a mandelbrot generator for the browser, but I avoid it at any rate.
HTML - still living in the 90s here.
CSS - something I've never spent enough time on to thoroughly understand, usually it ends up googling + tweaking + testing multiple browsers to find the things that work.
Javascript - I like javascript a lot actually, fun integrating it into otherwise basic web pages. See e.g. WHUMP and the auto-player-stuff on my blog. Lots of similarities to Lua, despite being completely different.
AI & ML - General ideas about how these things are done (side note, Francis was playing with small neural networks back in the early oughts for Winamp vis), but no real expertise to speak of.
Cybersecurity - What does that mean? Securing your systems against attacks? Keeping them up to date? Or attacking? REAPER - I do stuff with it almost every day. Probably use a small percentage of its capabilities though.
SQL - Can write basic SQL but for complex stuff I often end up RTFM Word - uhh is there any expertise to be had here? I do miss Wordperfect 5.1 though.
Excel - I know the diff between =SUM(A1:B2) and =SUM($A1:$B2), remember various functions (COUNTIF() maybe?), but for complex things it's RTFM time
Powerpoint - Stay the fuck away
