The pre-built labs are nice to start with for new concepts, so you get to learn one thing at a time and get comfortable with the command line and stuff.

After that I like to build my own, starting with two routers, pretending they serve different subnets and masks, and add functionality bit by bit, like routing protocols and DHCP, more routers, switches, etc.

I find the real value comes when you break something, and bang away it trying to fix it, and after spending hours to arrive at the one stupid mistake you made that broke everything, you never make that mistake again. Also, you get to learn from all those other things you tried along the way trying to fix it.

One invaluable tool to know and love is the Simulation tab in the lower right, where you get to pause the simulation and step it forward and follow your packet along, and you get to see just exactly where your packet gets dropped.

I'm not sure if this works for anyone, but I made it through the Lammle ICND1/2 book (and passed the tests) with a post-it with the number "60" written on it as kind of a "jumping bookmark". Instead of reading chapters, I made myself read 60 pages at a time, and moved the bookmark forward another 60 pages and read to that. You can use whatever number you want. 30 or 45 would work if you're a slow reader (I'm a slow reader but I have an abundance of free time).

It helped take my mind off the other 800 pages left, and because of the bookmark I didn't have to count pages or stare at the page numbers like "am I there yet am I there yet?" If I felt particularly motivated, or if I really wanted to finish a topic, I'd read ahead and count it as a head start on the next 60. The persistence really is key.

That's weird. I thought toe out only wore the tire out on the shoulder.

we got her back but she passed away during the night. Only solace was her family got to say goodbye while she was alive technically at least.

My grandmother passed away earlier this year, and we had one of those "last chance to say goodbye" moments.

On behalf of my family and anyone else who has had the same, thank you for that opportunity.

I forgot to cancel my free subscription and got docked $9, and forced myself to look through for something to get. God, it's awful.

My grandma passed away this year, and the last time the Google Maps car drove by was 2013, and she was on her porch, face blurred, but anyone in my family would recognize her cardigan and shorts. I've been stopping by every now and then.

One thing I like to do is visit my neighborhood and sit down as a giant and look at my childhood home, and think about how much history and meaning there is in that little box. One of the things about VR that you don't really understand until you try it is, the sense of scale, and how big or small things are. I get a Pale Blue Dot feeling whenever I use Google Earth because of just how *small* everything we know is, in the grand scheme of things.

I've been wondering -- what is the true purpose of Packet Tracer? It was great for CCNA R&S, but gets a little spotty for the CCNP R&S, but at the same time it includes a bunch of stuff that is out of scope for both.

Are all these other features intended to get you through the other CCNA tests (i.e. ASA's for CCNA Security)? Does it cover all of the CCNA's?

It's made so students in Netacad worldwide can get some hands-on with Cisco. Meaning it should be lightweight and be able to do most ccna rs stuff. That's about it.

The worldwide part is a important one as many countries simply won't have physical labs or i7/16GB RAM machines in their computer lab.

As a student you can get into networking relatively quickly/easily with it and your Netacad courses. But for professional users? Nope thats not what it was made for.

That part makes sense to me, and I agree it was great for R&S, but how about things like this update, with the ASAs and Merakis?

I mentioned this under the "how do loops happen": never underestimate human error.

Sometimes people cut corners or aren't as careful as they should be, but sometimes people make honest mistakes trying to be helpful. Someone sees an empty port and a loose cable, and plugs it in, and there's your broadcast storm. The person vacuuming some stuff in the closet doesn't know how light of a touch you need to throw the power switches on a 6509, and suddenly 200 people ask each other if their internet is down too.

Don't think you can accidentally make a typo or unplug a cable and go "oops" and put it back and hope nobody notices. Even if the network is down for a second, that means dropped calls and videoconferences (think embarassed executives), missed stock trades, and general pandemonium because people don't know if they can rely on the network and they start hammering the service desk.

And god help you if you accidentally fat-finger the interface number and make a change on the uplink port on a switch you're telnetted to. That drops your connection (along with everyone else's), and now that it's got the wrong IP/mask on the wrong vlan, there's no way to get back in and fix it other than to grab a console cable and get your ass down there ASAP.

I've definitely never made that mistake. Nope, not me. Nuh uh. That person should definitely have gotten fired.

Edit: To add, this isn't really to say "everything is scary and don't touch anything." It's more to highlight the reason for all the nice safety features Cisco has implemented, and also included on the CCNA, like port security and spanning tree protocol, which are easy to dismiss when you think you have total control over everything.

more often then not the people at our branches take their phones plug in from wall to sw port on their cisco phone, then plug the throughput port or pc port back into the wall in another jack, essentially taking that port down. now if you do not have settings in place in a switch you can take down an entire switch/network with a broadcast storm. spanning tree is your friend, and bpduguard is a good tool too.

see more

To add to this, on the "why would anyone do such a thing", sometimes someone will go "Oh look, a loose cable and an open jack, I should maybe plug this in." not knowing the other end is plugged to the other jack, which goes right back to the same switch.

We've had broadcast storms in the past, where previously the admin would disable bpduguard on some ports because a developer needs to plug in some switches for a lab (life would be too easy if we could just say no). Everything works fine until the developer moves desks and takes his lab with him, and a regular user moves in with his phone and PC with the bpduguard still down on those ports.

"Oh, look..."

When disabling bpduguard, you would enable port-security and that would have prevented the second user surprise?

If only someone had told the admin...

Is this more of a joke or do you actually see needles down by the beach? I fish on the beach frequently from greatkills down to tottenville and I have yet to see a needle. Lots of scattered trash, but no needles

I haven't seen needles themselves but I've definitely seen caps at Midland beach, and where there's a cap there's an uncapped needle somewhere.

I am also in a red district. A canvasser for the democrat house candidate stopped by the other day, and that was the first time I ever took the time to speak to a stranger at my front door without cutting them off mid-sentence (we get a lot of door to door salespeople). He asked if I was aware of the candidate, Max Rose, and I said "Yeah, we voted for him in the primaries." and wished him luck in November.

It's still a long shot, but I'm really curious to see how the midterms play out in my district.

Unfortunately the repair fees had to be paid using an IBAN transfer, which is nearly impossible to reverse.

I passed my ICND1 (948) and ICND2 (892) and I honestly couldn't tell you how I'd do on the full CCNA, just for the wide range of subjects you need to keep in your head for test day.

Now, onto the CCENT, two years (plus the 5-6 months from here to January) is a long time, and details tend to fade, and these tests get you with the little things like, "If you want to know x, would you type show cdp neighbors, or do you need to type show cdp neighbors detail?".

Now that you're reading everything the second time, it's actually going to be a bit tougher because you're going to have to go back and read a lot of this stuff all over again, and it's even easier to get bored of the parts that were already boring the first time around and miss those little details. Do whatever you can to not get bored or overconfident, and give every topic an honest read like it's your first time. I find a practice test or two is a good reality check on how good you are on the topics.

THAT SAID, the good news is that now that you're taking the split tests, you get to really focus on each half at a time, and 6 months is plenty for the CCENT. Good luck!

Only if the muzzle flash is bigger than the gun.

That line really struck me as I have a few memorable moments behind a camera where I didn't take the picture for one reason or another.

Do things very early in the morning. Wake up and hit the streets by 7am. You'll be amazed how much more enjoyable things can be when all the tourists are still in their hotels. Stop somewhere for a bagel or a bacon egg and cheese and coffee, continue on. Stop for lunch and take the rest of the day to explore some of the more quiet spots that /Kxmee mentioned.

I can't believe this never really occurred to me.

I work in Times Square which is usually a shitshow, but sometimes I get called into work early, like 7am, and it's mostly empty except for the people who actually work there, setting up shop. There won't be much to do with everything closed, but it's Times Square and there's nothing worth doing here anyway, so at least you get to see it and check it off the list.

Oh, and don't talk to the monks.

I just wanted to share this experience I had a while back:

I had just boarded a plane home from Vegas, and a guy got on the plane and stopped in the aisle and announced, "Excuse me everyone, sorry to bother you but, my name is [name], and I just wanted to explain that I have a condition called Tourettes Syndrome, which causes me to make involuntary noises and movements. I just wanted to apologize in advance for this, and I will try my best to stay quiet for the flight."

And some asshole in the seat behind me piped up and said, "Hi [name] my name is Matt, sorry to bother you but I'm extremely tired and if you wake me up during the flight I will put a pillow over your face."

I guess he thought he was being funny but the joke fell dead and everyone went quiet as John stared at Matt for a moment in disbelief like the rest of us. And suddenly he started ticcing, "Matt... M-Matt... Matt." and went to sit in his seat with his head down, which was a few rows behind Matt's.

For the rest of the flight, we would occasionally hear, "Matt. F-f-f-fuck. Matt." It was probably all embarrassing to [name] but I think we all saw it as his retribution.

I forgot the guy's name, but to this day, I remember Matt's because he had to go make a villain of himself.

I drove past there around 7ish. At the time there was only one cop car, two cars, and a few people standing around under the overpass.

Looked like a T-bone accident.

edit: I will defer to VizualMike96

Agreed. I love me some trap and skeet. Going by how the one on the Friendly 45 range feels, I think it would translate extremely well to its IRL equivalent, and I could definitely use some work on my skeet.

If I were to allow myself one Anton plz, it would probably be this.

I'm going to take the opportunity to mention that I discovered this the other night (sorry about the mouse cursor):

Maybe I wasn't clear enough, I was imagining the user would line up the magazine with the well, just like they do now, but instead of it just snapping into being fully loaded, it would snap into alignment with the well (and possibly disable physics interactions to avoid glitches) and the player would just need to one more (imprecise) push to seat the magazine.

That seems like it would mesh well with "those who handle firearms proficiently don't worry about insertion but getting the mag and well aligned." While also not having any more physics problems than the current implementation, and it hopefully could be used to fix some of the existing issues like like getting P90 magazines through that little archway thing.
