@@akhilmachaan5010, Of course, you can. A college degree is getting less and less relevant nowadays. Just get yourself familiar with it by practicing on a real system and real scenarios, like setup a server with different users and trying to do as much tinkering as possible, in about two to three months you can start looking for jobs.
notes to self: - UEFI replaces the older BIOS - GRUB is how the computer transitions from bios to the actual OS - when you upgrade a system, the old kernel is kept as backup and you can restore it if things go wrong - the Linux kernel is very efficient because it is modular
Duração do martírio de Maria. 1. Maria é realmente uma mártir. Jesus é chamado Rei das dores e Rei dos mártires, porque em sua vida mortal padeceu mais que todos os outros mártires. Assim também é Maria chamada com razão Rainha dos Mártires, visto ter suportado o maior martírio que se possa padecer depois das dores de seu Filho. Mártir dos mártires é por isso o nome que lhe dá Ricardo de S. Lourenço. E bem lhe pode aplicar o texto do profeta Isaías: Ele te há de coroar com uma coroa de amargura (22,18). A coroa, com a qual foi constituída Rainha dos mártires, foi justamente sua dor tão acerba, que excedeu à de todos os mártires reunidos. É fora de dúvida o real martírio de Maria, como assaz o provam Dionísio Cartuxo, Pelbarto, Catarino e outros. Pois, conforme uma sentença incontestada, para ser mártir é suficiente sofrer uma dor capaz de dar a morte, ainda que em realidade se não venha a morrer. S. João Evangelista é reverenciado como mártir, não tenha embora morrido na caldeira de azeite fervendo, senão haja saído dela mais robustecido, como diz o Breviário. Para a glória do martírio, segundo Tomás, basta que uma pessoa leve a obediência ao ponto de oferecer-se à morte. Maria, no sentir do Abade Oger, foi mártir não pelas mãos dos algozes, mas sim pela acerba dor de sua alma. Se não lhe foi o corpo dilacerado pelos golpes do algoz, foi seu bendito coração transpassado pela Paixão de seu Filho. E essa dor foi suficiente para dar-lhe não uma, porém mil mortes. Vemos por aí que Maria não só foi verdadeiramente mártir, mas que seu martírio excedeu a todos os outros por sua duração. Pois que foi sua vida, senão um longo e lento martírio? Glórias de Maria. Santo Afonso Maria de Ligório.
GRUB is just the most popular bootloader. The are others like uboot that are more common on embedded devices like firewalls/routers and handhelds but on x86 machines you'll see GRUB must often.
One of favourite channels ....I didn't visited a single day in college during lockdown and all I got job in security Engineering.... thanks freecodecamp community.... Great work
@@akhilmachaan5010Honestly it's very difficult. You have to prove your expertise in that area and without a proper degree it takes a whole lot of time and effort.. But yeah its possible
Saved my life with linux. I recommend any Elementary user of linux watch full video before going to become frustrated with linux. Its really handy for new to intermediary user of linux. ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Fantastic Course. Shawn is really good at explaining all this. I used to do sysadmin for Linux but needed a refresher after not being deep in the weeds for 10 years
Very nice, Instructor Mr. Shawn Powers is amazing the way he explaining everything.... In my MS in Computer Science, Unix course instructor didn't taught in whole semester, he explained in 5.5 hrs.. thank you
I'm simply amazed with the quality of your content. We want to thank your effort and hours invested. Simply one of the best intro videos I have ever seen!
Thanks for the detailed yet easy-to-understand tutorial. The instructor is so fun (I also watch him through his comic series, My Big Round World.) Thanks!
Hey guys.. I'm just watching this and liked this course as well. So what about that "My Big Round World" comic series? I don't know about that, please put the link here, I just couldn't find that
I saw many videos for Linux even with my native Arabic language but this video is the most interesting and fun and things looks easy. thank you very much
I very much appreciate this epic training session. You have a gift sir. 55 year old old fart IT guy here... 80% in Windows. Yeah, I know, been thru dll hell, and 13th level of Dante's Windows Registry hell. But, I've been running Linux for last 2 years on my daily driver laptop. It's all just text files? Son of uh... lol. Started with Ubuntu, and I'm very happy to get rid of Windows in my life. Thanks to great videos like this one, now I'm moving on to installing linux server versions. Great tutorial. Thank you!
I am not a native English speaker. But the author explains in such a simple and accessible way that even with my level of English, I enjoyed taking this course. Thank you very much.
The first 4 hours are awesome. A refresher for someone who is familiar linux already and a good starter for those who don't. After around 4:20:00 the topics become very high level theoritical nuggets.
@@disrael2101 Well I just did and my comment apparently got deleted so I won't do it again. But basically it boils down to the fact that you're still managing Linux servers. You just don't have to deal with the added overhead and complexity of hardware management, (physical) network management, and having your own data center. What's funny is that the least useful part of the course in the "cloud" respect is the first half-hour (or whatever it is) w.r.t. booting and the kernel, contrary to what the guy's comment said. I'd still recommend you go through that though. Maybe you need to build a custom kernel at some point, in which case it's good to learn about initramfs, kernel mods etc (I didn't watch this in depth, just skimmed -- idk exactly what he goes over point-by-point). Also it's just interesting stuff and generally helpful background.
Such a good course giving an idea on all aspects of working unix .. these topics are exactly what we'd be doing in real world .. thanks a bunch for filling my gaps !!
Very important video !! 👏👏👏Congrats there's a big difference between knowing Linux as OS and knowing how to Linux as a server or on a server environment 2 totally games to understand related though!!
Thank you for sharing this wonderful wonderful course with us. Have always been interested in learning about Linux and this sure cleared a lot of things. Thoroughly enjoyed! Have a great day!
So, Shawn explains that initrd is completely different from initramfs. Based on the below note from the Linux+ Study Guide, it seems like they're saying that initrd is the RAM disk file for Red Hat systems while initramfs is the RAM disk file for Debian based systems. Can anyone clarify? "If you install new hardware on your system that’s required to be visible at boot time, you’ll need to modify the initrd file. You can create a new initrd RAM disk image containing modules for the new hardware using the mkinitrd command in Red Hat-based systems. For Debian-based systems, the file is called initramfs , and you create it using the mkinitramfs command. Alternatively, you can use the dracut utility, which creates the initramfs image from a framework and copies files from the installed modules."
Very good!!! But I missed a very important content: BIND configuration. Especially because the title is "Linux Server - System Configuration and Operation". Hope you guys fixes it!
thank you for wonderful video, could you make a video about hosting own server and deploying web application on it, with home computer internet and also versus with on cloud with the full process simplify😁
Really provides great insights into Linux, many of the basic concepts got clear. Really appreciate it. One suggestion though, for Linux PKI there could be some hands-on added to this course.
Explanation of RAID5: For a 4 drive Raid5, when data is written to an allocation unit or sector, the same numbered allocation unit on all four drives are examined. three drives will have real data and one will have a truncated sum or checksum of the other three sectors added up like huge numbers. the location of this sum sector isn't always on the same drive for all sectors so each drive shares a portion of the checksums. Every time a sector is modified, the checksum is recalculated. If one drive fails, there is still enough information to "recalculate" the lost data even on the fly until a new drive is installed. If the bad drive had the checksum for the given sector, then nothing needs to be done. But if the bad drive had real data, the checksum for this sector is subtracted by the other available data sectors to recalculate the bits in the missing sector on the bad drive. Raid6 works the same except that there are two checksum sectors instead of one. This allows the raid to lose two drives and still function. I have seen Raid5 arrays with 9 or 10 drives which maximizes the available space but slows down the array if there is a failed drive. a 4 drive array with a bad drive is recalculating 75% of the time while an 8 drive array with a failed drive is recalculating 87.5% of the time.
