Yo Eli (no i'm not stealing your name, my parents did that) I'm watching this in 2020. I started as a servicedesk agent in a pretty big IT outsourcing company. Today I'm a support engineer on his way to becoming a system engineer. Your video's have helped me a lot and still do. Thanks for all the work you put into this.

[@ArcardMgendi]

I started listening to Eli back in 2013 before I did enrolled for an ICT Course. I am here 10 years later and the content is still relevant to what I am currently doing. You are so great Eli👌

[@christinaboccadoro9328]

Hello Eli Sir, You stepwise introduction of key elements and important concepts in Computer science does help me a lot in grabbing knowledge of computer world. I am a recent non computer science graduate from Hong Kong now working in IT industry.Your videos really gear me up. Thank you very much, Sir.

[@jpeters9009]

This is for people who are serious about the invaluable knowledge imparted by Eli. I wish that viewers respect this and refrain from posting idiotic comments not relevant to the subject under study. My heartfelt gratitude for these outstanding videos.

[@jamespatterson6972]

This is indeed a FANTASTIC set of videos. Got me rethinking the notion of building my own server. I build my own PC's but never stepped into the deep waters of computer servers. I need to study these videos some more. A lot more!

hi

[@LNDCRUZIN]

I love this dude, I watched most of his videos throughout a period of 6 months and thanks to him I’ve been working in IT for well over 1 year, I’m making good money and I’m so grateful for Eli!

[@AnalyticalSentient]

Thank you for this, sir! I admire the free uploading of this educational content (time and investment put in on your part, etc.)

[@AnalyticalSentient]

jwahh Were _you_ required to pay for this educational content? No; that was my point. Furthermore, I doubt that he is 'rolling in the dough'; the compensation that he does receive from what you accurately referenced nonetheless may well not be completely proportionate to all of the time and work that he puts in to researching, composing, editing, uploading, and annotating the videos here. But I do acknowledge and understand your point.

Hi Eli, I’m happy to see your returning to YT with the Dojo. Even though this series is almost 15yo it has helped me in my career and enabled a woman in tech. It’s amazing the impact you can do with your videos and the way you teach is so clear. Thank you!!

[@stesim]

In a word? Yes. This man's instructions are some of the most valuable tools I've found to date. Not only for Techs, but for those who are entering into the net field. The key is to LISTEN, and not be so petty regarding what his white board looks like.

I enjoy your videos and hope she continues to point us to them, keep up the good work man! (she may have come across your videos on her own too, either way i found my way here.)

DSL speeds can exceed 20 Mb nowadays. They've gotten over 100 in laboratory testing.

[@Silasapocalypse]

This video was made in 2009. Serviceable DSL speeds at that time were capped at about 20 Mbps. It has taken pretty big leaps in technology to get above the 20 Mbps.

[@thankgodwilson1142]

I like the way you teach I was lame before but your teachings broadened me

[@tombates9122]

You make a good point about the importance of using patch panels. I would also add that they can end up saving you a LOT of money in the long term. One of the biggest costs in any kind of medium to large network, is paying someone to actually run the cables through the walls/floors/etc. This cost can be minimized by having every wall socket cabled at the same time, compared to having to pay someone multiple times to do the same job, just to add a couple more cables through the building. Remember - it's not the cabling that is particularly expensive, but the labor costs of having the cable ran through the building. Patch panels make managing such an infrastructure much easier.

Thanks for the class Eli. I just want to point out that as of today from the date that you uploaded this video, I think that some things has changed a bit. The reason why i say this is because i just but a switch and as i'm checking the specs and what not, I notice that this type of switch is classified as PRO SAFE PLUS, L2, gigabit. I may be wrong but what this make me think is that this is a class in between unmanaged and managed switches. I just wanted to bring this point to you, which i'm pretty sure that you know what i'm talking about without a doubt, but may some viewers do not know what this is about since the video was uploaded back in 2011.
