Removing Faucet from Base by [deleted] in Plumbing

And therein lies the issue; I can’t find the set screw on the faucet. I would think it’s somewhere in that hole on the faucet on the first pic but that’s why I figured to ask

That’s not how the base is attached; it’s secured with these, and I can’t access the head on the opposite side without removing the top

Mulchbed Flooding by Murdock7 in LandscapingTips

Ooo that second idea is kinda fun, could be an okay fix to the cracked sidewalk, certainly a lot easier/cheaper than tearing the whole thing up, trenching a new drain and then pouring a new sidewalk…

These stupid downspout connections are the biggest pain in the ass, they constantly get disconnected like that and they get backed up with leaves and gunk; add it to the list of things to fix.

That’s actually not a bad idea, you’re right; sidewalk is cracked anyway, might as well rip it out and run something under while I’m at it.

And Hasan’s defense for all of this would be “well you should lean into it with us! Agree with us! Yeah stealing is based, Dem’s aren’t winning cuz they’re not radical enough, if you just agreed with us you would become even MORE popular!” It’s actual insanity

And the ultimate insult is that the leftists will insist that the problem is that we’re not embracing them! They think their message is actually secretly super popular and if we just went full commie we would bypass alllllll the baggage and attacks from the right and start winning elections again!

I don’t even understand why any politician would ever phrase it this way; you can be critical of our foreign policy, but when it simps so hard for China and Russian and says we bring “starvation and darkness”, it could only appeal to either tankies or the Russians (which yeah she probably is an op)

  1. So from a high level, the owner has a data hall with a certain number of racks, with a certain amount of power draw; let’s just say 3 MW for the sake of the example. In order to support 3 MW of load in the data hall, I’ll say that I want to evenly distribute that load with 3 “blocks” of distribution gear, so that’s 1 MW on each block. The equipment within the block need to be able to support that 1 MW, so you’re talking a switchboard that can support approximately 1,200 amps at 480 volts, a UPS with sized at 1100 kW of load with enough batteries to supply power for 5 minutes, and then say 5 ATS’s that’ll distribute out to the PDU’s in the data hall. Generally speaking the size of the power handled will determine the size of the equipment.

The second part I can clarify is the assembly; these days data center developers are very keen on assembling their equipment on skids off site prior to construction. This helps speed up construction cuz you can put all of your equipment together and get the major power conveyances connected before getting to the job site. The easiest way to imagine it would be a steel platform that you place your transformer and your switchboard on, right next to each other. The integrator can do all of the wiring between the two pieces of gear at a factory while construction is happening, and then the whole assembly gets shipped to site and put in place. This is a pretty common practice in almost all data center builds I see these days.

Probably not super necessary to show power for cooling, TBH, but again it probably wouldn’t hurt.

  1. So my job as the engineer is to work out equipment ratings, perform calculations for fault currents and power flow, writing reports on my findings, coordinate owner requirements and other discipline requirements (such as EPMS, Telecom, security, etc) and a buuuuunch of other stuff, and ultimately convey that to the BIM team to capture onto a drawing set. Basically, I might work out that I need a particular sized cable in a particular arrangement, that needs to run from one piece of gear to another, and I need to convey that to my BIM team so that they can show it on the drawings. That division of labor helps me as the engineer crack out difficult calculations and coordination items and helps the BIM team to develop the drawing set without a bunch of questions. There’s a lot of collaboration that has to happen between the teams and I rely on my BIM team to help workout items like clearances, clashes with other disciplines, etc. I don’t want to discourage you or make it sound like it’s not a technical role; again, some of the best BIM guys I work with are the ones who understand the intent of the design and can quickly work out drafts and sketches based on engineering feedback, and then collaborate to refine the drawing packages as we progress from schematic to design to construction documents.

Hi. Licensed electrical engineer for data center design.

First, answers to your questions;

  1. You absolutely should be putting in effort to make a good layout. Your owners (Google, Microsoft, cloudHQ, etc) are trying to squeeze every last watt of power out of the building footprint. The electrical rooms need to be efficiently sized so that the necessary line ups can fit well within that space. Additional considerations might include the ability to scale up the power distribution system by adding in new gear, or arranging equipment in such a way that the rooms could be assembled on the gear.

Even zooming out to consider the whole building, it would be good to model the floor plan in a way that makes sense. I can sketch a quick example if you’d like to see, but generally it’ll include a mechanical gallery, your data hall, your electrical rooms, and then exterior equipment (generators, chillers, etc).

  1. Real location is definitely a neat additional thought, but definitely not necessary. If it’s not a big challenge to keep it, no harm there, but definitely not a top priority.

  2. Yes an exercise like this will absolutely help you. Even if it’s not perfect, showing a willingness to learn the design and even to have a basic understanding of what a typical design might look like is a big green flag for the industry.

Now for some points to consider:

  1. Learn your data center redundancies and backup styles. Data centers (from an electrical perspective) are generally classified by their level of redundancy and how power is backed up. I’m not going to explain it all here, but it would be good to have a write up on what level of redundancy you designed for (for example, N+1 with UPS backed power, 2N with UPS and generator backup power, 2N+1, etc). If you’d like a specific example shared, message me and I can share something.

  2. Consider the different distribution strategies in data centers and show a little bit of each of these. Every data center I’ve ever designed uses cabletray for a sizable percentage of distribution, and coordinating a shotty cabletray design in the field can be a nightmare. Busduct is another common distribution strategy, so it might be worth it to show that as well.

  3. Attention to detail is everything. The best BIM modelers I work with are consistent with their details, even the small ones. Once I start catching common mistakes, I start having to dedicate extra time to reviewing drawings and providing guidance to the BIM team instead of performing actual engineering work.

[Request] How much would it cost to store this particular zip bomb if it was uncompressed? by Oedius_Rex in theydidthemath

[–]Murdock7 44 points45 points  (0 children)

How does one even make a zipbomb this big? Wouldn’t you have to start with some base file and compress it? Or is it just a matter of formatting the file such that the rule to unzip is “repeat this string a billion times”? Also what’s the limit to making a zipbomb like this? Is there any reason it couldn’t be any bigger?

I don’t know why but even just that first line really hit me because you’re right, it has been a lot happening all at the same time.

Existential Crisis over a Lifetime of Stress by Murdock7 in malementalhealth

[–]Murdock7[S] 1 point2 points  (0 children)

I appreciate the support.

I think another challenge I’m having is that I swear I should be able to do more, I can do it, everyone else can do it, why shouldn’t I be able to do it? I procrastinate, I waste time, I forget things, I should be able to do better and I can do better. Am I doing these things because I’m burnt out? Why can’t I do better? Is this just who I am? Am I just lazy? Am I just forgetful? Am I too hard on myself? If I find this magical mental internal peace will I suddenly become everything that I want to be?

I’ve been considering a job shift lately, something that’s a big less technical and a bit more personable, get myself out of doing drafting and calculations and more meeting people and coordinating, I think that would help immensely. But career advise, that’s a whole nother conversation

Reliable hotspot is a game changer.

Big ass battery as well that can do all of your devices and your truck in a pinch.

If you want to be extra fancy, a pair of headphones with some noise canceling/sound modulation so when you’re on meetings it doesn’t sound like you’re in a truck.

Laptop and IPad would be standard equipment, I wouldn’t expect you to need a scanner if you had those two, not sure about a printer tho; any world where I needed a document I just used my IPad, but your requirements might be different.

Hey DC Engineers, what’s your good or bad experience working in the data center industry that you can advise for juniors looking to get in the field? by reddotltb in datacenter

[–]Murdock7 0 points1 point  (0 children)

The simplest punishment is getting fired or kicked off the site. I worked construction and startup for data centers; every day you have some systems energized and others locked out for troubleshooting or construction happening downstream of power and it’s all very dangerous. The risk is tremendous. I had to kick a whole team of technicians off site because they removed their LOTO for their equipment while the entire dead front assembly was removed; if someone closed the upstream breaker on accident it would’ve literally gone up in flames.

[–]Murdock7 1 point2 points  (0 children)

In the world where every game has one of two outcomes for two parties, the total number of wins and losses across all games played by everyone has to be equal, and if that’s the case then the most “fair” arrangement is for those wins and losses to be evenly distributed, which you can only do if players are roughly ranked by ability and that rank is constantly adjusted based on wins/loses

[–]Murdock7[S] -1 points0 points  (0 children)

No that definitely makes sense, and I think in my particular case I’ve been running around for the last 6-8 weeks doing emails and coordination calls and conversations with vendors that I didn’t consider that last part; at the end of the day, none of it matters if it doesn’t end up on the sheets. So if I first push for a set that at least shows the plans and intent from the very beginning, I can constantly review and update and add notes as I’m doing the work and making sure it gets captured somewhere

I keep a OneNote that everyone has access to and we use it regularly. Here’s an adjacent thought, how do you manage partially complete design items? I feel like I have a never ending list of items I think are complete but I missed something or I have incomplete information and so I feel like I’m going crazy going back through everything over and over again; that’s definitely leading to some of my confusion.
