I shall be studying for CCNA basically all day, except for a few annoying Bitlocker issues that have been coming up this morning.

Independent contracting/consulting is not "printing your own money" like people sometimes seem to think here. Unless you have very specific company, industry, or even technical experience, you don't exist in a vacuum so there is always someone willing to undercut you. So at least in my opinion there is no one flat multiplier. Like a job search, evaluate your competition as best you can and give a number that makes sense for you, knowing the higher you go the higher the chance of them saying no or finding someone else.

Moving on to the second phase of recabling the server room I'm focusing on cables between pieces of network equipment. There's a massive knot of blue cable hanging from the back of the rack so I started untangling it to find that it's actually four cables that run from the primary rack to the rack in the rear corner of the room. Found the end of a cable loom stuffed behind a cabinet that follows the same path. It has one cable in it that's not plugged into anything, and is zip tied closed every foot so as to discourage people from ever using it for something... useful.

I measured the run and bought replacement cables of the proper length along with a pair of snips to denude this place of every goddamn zip tie I find. Racing the clock to see if I can completely clean up the server room's extensive cabling mess before they can me.

Well to be fair, he didn't say NONE of the interfaces are allowing an outside connection. And in fact, if one interface is outside facing and is up, and he's trying to open another interface to the same outside network for some stupid reason, there's his problem.

I'm looking in to this New Relic thing for a potential job and while the server monitoring is neat and fast (at least compared to what we use at work), I don't have any web apps or web sites to monitor to check out that portion of the package. Don't suppose anyone knows of a python or ruby webapp that scrapes data or does stuff or something that I can install?

Or some server thing that gets put under load.. Maybe I should set up a personal news group downloader thing..

Because odds are that its due to an Amazon owned mobile app somehow not securing itself properly, and then Amazon security finding out about it, and then just force resetting the passwords of anyone who used the app from date X to date Y on the off chance that something bad happened. Or, something similar to that effect.

Some users are getting "reset your password" emails, not all users. If Amazon's central storage for credentials were compromised, that would be a huge deal and the response would be different.

(Pretty much DNS job/team related)

Is anyone here an DNS guru for a big corp (20k+ employees) Corporate DNS team job? I'm planning on joining a major [redacted]'s DNS team of about 6-8... From what I can see their 2 big projects are setting up Anycast BGP - between our data centers across our [redacted] country, and consolidation our like 10-15 DNS environments into a couple of InfoBlox Devices (including our Data Centers 8 diff versions of [redacted] (since it was designed by like 4-5 diff teams...

One of the teams decided to name reverse zone files at "arpa.A.B.C in the ./forward folder... (no reverse folder exists :negativeman: ) instead of C.B.A.in-addr.arpa (which makes delegating a bitch when customer wants the DNS delegated to their servers, and has it setup on his server as the C.B.A.in-addr.arpa...


Also if anyone is on a Big Company DNS team -- What type are certs/skill level are required... I've been pretty much a bind/named/MS DNS ( :smithicide: ) / for 10+ year


My Skills:
Python/Shell scripting is fine/intermediate, but I can make some nice scripts such as massive FCrDNS to see if these are still required/active customers.

Example: Not sure where my Syntax is loving up
code:
./testrdns2.sh 4.2.2

        address -> name -> address
-------------------------------------
ok      4.2.2.1 -> a.resolvers.level3.net. -> 4.2.2.1
ok      4.2.2.2 -> b.resolvers.Level3.net. -> 4.2.2.2
fail    4.2.2.50 -> dnslb1.bbnplanet.com. -> [unassigned]
fail    4.2.2.51 -> dnslb2.bbnplanet.com. -> [unassigned]

*****
fail    4.2.2.6 -> resolver8.Level3.net.
f.resolvers.Level3.net. -> 4.2.2.6
4.2.2.6
*****     

(I'm sure this is easy fix... but it doesn't bother me
too much as I made it in about 30mins, and spent 1-2 hours 
trying to figure out why it, I can't get this simple on 1 line
like the others... I'm sure its just some simple regex I'm loving up
etc...)
Setting up an RCS system because too many people kept loving up everything.... VI SO HARD! (not Nano/Pico/Etc allowed on these servers)

The new manager told me they want CCIE for the SR Role... I just have my CCNP... I'm well versed in Wireshark-analyzing, Captures/Everything DNS (Except Anycast BGP though I have a much larger grasp, and it makes a lot of sense to me since our Mega Data Centers are spread across our Data Centers, and our corporate network is :( as our internal networks routes to One coast, retrieves data, then sends it back all the way to the other coast... for every action (outside our OOB Network)

Any advice would be great, as I basically just want to work in a specialized DNS department... and it's pretty much one of the few things left I enjoy in IT.... and Automating my Tasks with scripts :)

It seems like an okay place to work but their stock price has been hit hard and revenue decreasing quarter after quarter.

Hopefully, with their recent partnerships things will turn around or maybe a buyout will come to fruition. Which may certainly shake things up if you do become employed.

Sounds like you'd be a great fit and a lot of people don't know DNS beyond the hosts file and A/CNAME Records.

The only thing I'd be curious about is if take this job, invest 2-3 years into and you get laid off - how difficult will it be to find another DNS technical role?

Not that I'm saying I wouldn't take a job because it might be difficult to find one but it's something you probably be aware of.

The idea that slack time is necessary for successful projects has been covered in lots of books from Goldratt's The Goal (where the focus is on the Theory of Constraints) to Berkun's Making Things Happen to Kim/Behr/Spafford's The Phoenix Project (itself an IT-oriented adaptation of The Goal). The underlying concept is easy: in any project where people are working together on something, you encounter situations where people are blocked on their own work waiting for someone else to handle some prerequisite. If that person is jammed up on other higher-priority or more urgent work, they can't remove the blocker, and now the first person just spins because they're unable to progress on their tasks. Slack time is necessary because it allows people to rearrange their work items around what will unblock other people, instead of forcing a focus on individual throughput.

In highly complex organizations and projects, this can lead to a form of gridlock, where a circular dependency is introduced and it becomes literally unresolvable without someone stepping in and changing the parameters of the project. Here's a useful visual aid using traffic as a metaphor for throughput:


(All of the buses are unable to move, because each bus is blocked into the intersection by other buses going a different direction. Traffic will not move in any direction until someone decides to take an alternate route.)

I don't know about any 70% number, but it sounds like the kind of rule of thumb that Thomas Limoncelli would use. Maybe it was in Time Management for System Administrators?

I'm not really qualified to go into depth on the math, but it comes from queuing theory.
One of the basic queues M/M/1 has a knee at around 70%. At that point you start getting proportionally more stretch factor than you gain in throughput.

It's not safe to assume that your queue will be equivalent to M/M/1 though, so your mileage may vary.

College algebra or college-level stats? Did you have any calculus?
My own experience with queueing was very limited since I did more calc and physics but I want to say it was heavily rooted in statistics (probabilities and expectations). Resource sharing and scheduling are more general areas that you'll need some bits of, so bust out that operating systems theory book, too.

I double-majored in math and have a great memory for basic differential and integral calculus but don't remember much of Calc III or IV (Taylor/Maclaurin series, etc.). I took a basic stats course and still have my textbook (Miller and Freund's Probability and Statistics for Engineers), but I don't remember a ton (though I'm sure I could relearn easily). I'm real rusty on notation and get lost in a big hurry when I read formulas on Wikipedia full of un-referenceable, apocryphal Greek letters.

I'm really intimately familiar with how things like resource sharing and scheduling work at a practical implementation level, but I've glossed over the theory until this point.
