BOFH: This printer engineer knows every trick in the book

timmy 2

well, you simply must take into account the facts.

1) interns are young

2) we know intern is female, so young

3) the PFY was being very polite (moreso than normal) , so intern is young and probably quite attractive

4) she's presenting them with a computer problem that allows them to mess with the vendor instead of the end-luser

all in all, they can be forgiven because putting a vendor in their proper place takes priority over berating a young attractive female end-luser

Re: "the sound of a large multifunction printer hitting a small white van from a great height"

he did say... "So," I say, "what I need you to do is this: take this printer up to the fourth floor..."

assuming a standard height per floor for buildings of roughly 10ft/floor, which across the pond would equate to the FIFTH floor, with a window height of 3' , but then the target area (van roof) sits about 5' above the ground, so let's just say 48ft (14.63m) . Btw, do not forget to include land elevation above the Thames (assuming that the BOFH is located in London) as a factor of Rho. For this exercise, you may assume that all of London is a flat surface and use an average reading. Points will NOT be deducted from your final answer.

The terminal velocity of a free-falling object is calculated using the formula \(v_t = \sqrt{\frac{2mg}{\rho A C_d}}\), where the key factors are the object's mass (\(m\)), gravitational acceleration (\(g\)), and air density (\(\rho \)), cross-sectional area (\(A\)), and drag coefficient (\(C_{d}\)). It is the steady speed reached when downward gravity equals upward air resistance.

The Formula and Variables

\(v_{t}\): Terminal velocity (m/s)

\(m\): Mass of the object (kg)

\(g\): Acceleration due to gravity (\(9.8\text{ m/s}^2\) on Earth)

\(\rho \) (rho): Density of the fluid/air (\(\approx 1.22\text{ kg/m}^3\) at sea level)

\(A\): Projected cross-sectional area facing the wind (\(\text{m}^{2}\))

\(C_{d}\): Drag coefficient based on shape (dimensionless, e.g., \(\approx 1.0\) for a skydiver belly-down, \(\approx 0.47\) for a sphere)

You now have all relevant information to supply us with an answer. We've even supplied some rudimentary support from https://www.omnicalculator.com/physics/terminal-velocity

Re: Bad data coming in

there was even a lawsuit over it. I don't recall the exact details but it boiled down to "<condition 1>, <condition2>, <condition 3 or condition 4>" . the gist being there were only really 3 conditions, not 4.

in the Tom, Dick, Jane and Harry example given above it could be argued that there were 3 people not 4. Tom, Dick, and 1 named "Jane and Harry".

some of us should be as lucky as the OP

I did something similar ~2010. Part of my duties involved unlocking AD accounts in a rather large domain with multiple sub-domains having 1500+ each users each. Every few months we'd have to pull overnight duty and respond to unlock-account requests from night-shift users who would lock themselves out. Problem was, the notification system really didn't work well...at all. So rather than hear about it the next day of why wasn't I doing my job from the micro-managing nitpicking screaming btch of an incompetent manager who knew the notification system was broken, I decided to have a little script find the locked accounts and I'd unlock them.

So I created a script, tested it, but it didn't seem to be working, and I ran it a number of times against our sub-domain. Finally figured out the script was working but wasn't finding any locked accounts because there weren't any (unusually)! Yay me! Running against another sub-domain found locked accounts. Proof it works, ready for my next overnight shift in a week or so.

I come in the next day, need to check a few things requiring Admin privileges so try to login with my Admin account...but it's not letting me. OK, login normally. That's weird, my Admin account is locked out but my regular account is not? Send off an email to the SWMNBN btch manager (She Who Must Not Be Named; yes, this was one of our official references we used to refer to her) saying my Admin account is locked out. She calls back 3 HOURS LATER to ask why I was running scripts against AD. Ummm, because I was searching for locked out accounts to make sure I didn't miss locating any when I had to look for them? "No one gave you authorization*, <blah blah blah> <rant rant rant>... don't do it again" ..... "Sorry <that I ever decided to take the job working for a sanctimonious btch like you>"

*actually, my job and my responsibilities grant me authorization you moronic bint

Used the script from thereon, waking up a few times during the night for 5 minutes to run the script. Was worth getting interrupted sleep instead of dealing with her stupid self-righteousness. She never knew the effing difference (and I was finally out of there 12 months later).

Server-room lock was nothing but a crock

server room door lock

Our server room was in a 100 year old building, only had a spring-loaded deadbolt key lock on the door (tightfitting door original to the building) that opened outwards so they decided to install a battery operated electronic lock. Sure enough the batteries died a few years later (no published battery replacement schedule), we NEED to get in there. Maintenance took a look at the door, took out hammer and pin punch and proceeded to knock out the hinge pins, then used a thin prybar to pop the door out of the frame.

yep, battery replacement maintenance schedule published a few days later.

Re: Not a gaping hole in the network, but .

25+ yrs ago I was working for a state agency and we really needed some backup server hardware but no budget. "No problem" (says I) because I have access to the state surplus IT equipment list. Found 2 servers being surplused from another agency that were WAAAAAAY overkill for our needs, Dell 4300 with full complement of SCSI hard drives and DLT tape backup (all I really needed was the DLT drives for backing up the data on our in-house server).

Imagine my surprise when I booted them up and they had a full operating system! Further investigation found they had been running Exchange server and still had everything stored. Looked up the previous administrator and found out "Hey, that's my old buddy <redacted>!" So I called up "John" and started feeding him some rope. He got embarrassed since it was his job to ensure they had been wiped. He ended up sending a subordinate over to low-level wipe the drives which took him about just over an hour per drive. That individual sat there all day just reading the newspaper, moving only to start the wipe on the next drive.

I still yank my buddy's chain to this day even though he retired 10 yrs ago. Call him up randomly for a chat and tell him "Found another one!"

Re: Hilarious

partially correct. doctors have to record long treatment notes into dictation machines, that coders then transcribe into the computer systems. working in health sector IT, I have seen these treatment notes exceed 10 minutes in length and sometimes up to 30 minutes. can you imagine having to write that all out instead of moving onto the next patient? on top of historically terrible handwriting?
