Small insignificant correction: The reason that modulo 10 is 0 through 9 is because those are all the possible remainders when dividing by 10, not because computers start counting at zero.

[@D.a.n_D]

to make your answer clear, here is a example: dividing 93 by 20: 20 + 20 + 20 + 33. the reminder can't be 33 because you have a 20 in 33, so it would be 4 of 20 and a 13. that's why you put % 20 to a number between 0 - 30k, to get something between 0 - 20. Also a quick math to getting random number in an interval: randMinMax = random() % ( Max- Min ) + Min if min = 20, max = 33, for first expression : you get random % (33-20), so random nb from 0 to 13. and then you add 20 to it, so you are in the range over 20, and under 33.

It's all clickbait for money. There's an entire reddit thread about him doing this crap. Typical KZbinr desperate for donations and money. If he was sooooo good at hacking. Why doesn't he have a job? Doing KZbin for a job with clickbait isn't a job.

@@PrinceAndrewFucksKids I agree at some point with you, his thumbnails are extreme. But if you dont make clickbait nowadays, you will not make it into the algorythm. Without clickbait, many youtubers would need maybe 10 years for 1Mil. Clickbait accelerates it significant. Whatever, atleast he is showing something interesting, or relevant, or "good to know thing". Better than content thieves and commentary channels, sitting and talking about some exposed person.

[@PrinceAndrewFucksKids]

@@bendze I won't disagree with you there mate. In that sense I support your reasoning. Have a great day. It Always helpful and positive to see a different perspective you'd may not have seen otherwise.

[@bendze]

@@PrinceAndrewFucksKids you too, yeah luckily there are still some people left with some reasonable opinions amongst the comments. I dont blame the fanbase at all and the positive feedback, but lots of fans say what the youtuber wants to hear, like being too emotional and only saying "omg I needed your video today" and at female ones "i love you so much" Self confidence is only based on fans who already love the creator and constructive criticism is a rare card here.

I think its hilarious that Linode gives you 100 dollars in credit for 60 days even though if you used it 24 hours a day every day for 60 days, the total would come out to $14.40, so unless you were running about 6 different operating systems at once with Linode 24 hours a day for 2 months, you wouldn't need more than like $15.

[@Halolalol]

You can just set up a more powerful and therefore more expensive system in that time, this way you can take advantage of the 100 Dollars.

you are great, I just found you my accident.

Thank You Chuck! This was the Linux intro I needed. I noticed you updated .bashrc for restarts and export for child processes, but I wasn't sure if the variable applied to all users, or how to set a variable for all users? Great video! Big fan of your presentation.

[@audiolatroushearetic1822]

The .bashrc in your homedirectory only applies to the user to who it belongs. If you're on a proper linux install (bare metal or vm) there's also a .bashrc in the /root directory (sudo nano /root/.bashrc) but the better way to set permanent global variables is to put it into the '/etc/environment'-file (just how you would do it in a normal script). Log out and back in again and you're ready to use it.

[@agentlogan4760]

I clicked on this so fast. Thanks for all you do! Your content is top notch

[@zsi]

I do pentesting and red teaming... I largely live in Bash scripting because at higher levels of expertise in hacking, you simply cannot get things done with tools someone else built (and oftentimes, the tools you want do not exist). The people that claim you can be an expert hacker, pen tester, or red teamer without knowing how to write scripts or code in Python or some other language are misleading in their "wisdom" because they do not know what they do not know.

[@mrwhosmynameagain]
