    Why don't request TLD Servers directly?

  12. @sreerajnr9888

    October 13, 2024 at 11:08 pm

    I was wondering why wouldn't the resolver directly ask the authoritative name server for IP address instead of asking the other two servers who do not know anything other than rerouting to next server?

    Thanks

    So I know the ip address of a website, I don't have to go through my service provider to access the page?

  15. @asifkhowaja7817

    October 13, 2024 at 11:08 pm

    Isn’t it a recursive server which send queries to root server or resolver server is another name of recursive server ?

    A very large company has about 70 branch offices, I've noticed that all the branch offices have IP scheme of 192.168.1.x for their respective LANs. However, the headquarters is using 10.1.10.x for its LAN , could anyone tell me why that is?

  24. @mauriciobatista952

    October 13, 2024 at 11:08 pm

    Once the resolver gives me the IP address, does the cache memory of my computer store it? How long will it be stored?

  25. @francishubertovasquez2139

    October 13, 2024 at 11:08 pm

    Domains was scripturally mentioned. Not domains of Angels but domains guarded by Angels. That's your function am I right. Look at this variations because it's plural. Dome in ( Dome science covered habitat ) , Do main( centralized ), Do Ma in ( matter focused with mass ), Do Me INternetwork System etc, it speaks of variety of servers within.

    I'm noticing something about my habitat companions several times already, transformable demeanors per situation, unstable in attitude bloodline. A question mark? Being hoppings?

    Can you tell me who manages the who manages the TLD and authority name server

    Can you please make another video on DNS server because when I do a DNS lookup I am getting different IP addresses of the same website like the DNS lookup service provider saying that the IP address may be different for different locations. Why this happens. Also explain how CDN are responsible for this and how DNS is able to co-ordinate with CDN. EXPLAIN IN DETAIL THE FULL PROCESS. 🙏

  33. @deovratj1990

New Home Backup Server (Dell T640 with 18 20TB Disks)

New Home Backup Server (Dell T640 with 18 20TB Disks)



In this video I create a new backup server from a Dell EMC PowerEdge T640 with 18x 20TB Seagate Exos refurbished drives. Also there’s some more ranting about backups in general. But idk, there are chapters so you can skip to whatever. And it’s not technically a server, in that it doesn’t serve files. It’s really more of a client that takes files from other servers and holds onto them. But I call it a backup server because hardware-wise it’s a server. Anywho, that’s the description. It’s probably not optimal for the YouTube algorithm, but hey, I’m not an influencer even though I have a TikTok account that I don’t use.

Update: https://www.youtube.com/watch?v=Secv5P01k2M&t=5195

00:00 Intro
02:08 The Drives
03:30 The Data & Other Backups
05:40 RAID & Data Loss
10:00 IcyDock ExpressCage
13:23 Fan Noise
18:30 Caddies, Trays, or Sleds.. Whatever
28:27 Booting & Array Creation
33:50 Array Build Status and Drive Stats
36:43 OS SSDs and T640 Internals
58:20 Lengthy Conclusion (Backups Rant.. again)

The Man Who Revolutionized Computer Science With Math

The Man Who Revolutionized Computer Science With Math



Leslie Lamport revolutionized how computers talk to each other. The Turing Award-winning computer scientist pioneered the field of distributed systems, where multiple components on different networks coordinate to achieve a common objective. (Internet searches, cloud computing and artificial intelligence all involve orchestrating legions of powerful computing machines to work together.) In the early 1980s, Lamport also created LaTeX, a document preparation system that provides sophisticated ways to typeset complex formulas and format scientific documents. In 1989, Lamport invented Paxos, a “consensus algorithm” that allows multiple computers to execute complex tasks; without it, modern computing could not exist. He’s also brought more attention to a handful of problems, giving them distinctive names like the bakery algorithm and the Byzantine Generals Problem. Lamport’s work since the 1990s has focused on “formal verification,” the use of mathematical proofs to verify the correctness of software and hardware systems. Notably, he created a “specification language” called TLA+ (for Temporal Logic of Actions), which employs the precise language of mathematics to prevent bugs and avoid design flaws.
