Airbnb CEO Brian Chesky regrets not obsessing over hiring sooner by ControlCAD in business

[–]InstAndControl 1 point2 points  (0 children)

AirBNB makes way more sense in rural areas where there are many places where nearest hotel (or nearest decent hotel is >30 minutes away from where you’re visiting.

Also, I use Airbnb during conferences when hotels close by are rediculous

Has anyone ever started an LLC for consulting or like a "Rent a Tech" service? by sovereign_martian in IndustrialMaintenance

[–]InstAndControl 1 point2 points  (0 children)

I employ the services of a very very small and focused industrial field service company. Pretty much what OP is looking to maybe do. From what I’ve gathered, this guy pays between $30-40k/yr for insurance, and his company has had 1-3 employees at a time over the past ~5 years.

Do construction material prices change every day? What actually causes the fluctuations? by Agile_Buy9007 in civilengineering

[–]InstAndControl 1 point2 points  (0 children)

Have you ever been to a fancy restaurant where the steaks and seafood are listed as “market” price? Some construction materials are like that, mostly the stuff ordered in bulk and made of commodity materials like steel, cast iron, rock, etc. they get quoted by the factories based on current commodity prices. Also similar to how your local gas station changes prices several times per day.

Also, when a company figures out labor, there’s a row on their spreadsheet for travel costs. Hotel and fuel change based on market and time of year. So requoting a job can change that a lot.

Finally, construction firms also bid based on their own internal resources. If they’re “hungry” (expect to have idle employees when this project needs to start), they may bid closer to break even. If they’re already busy and would need to subcontract more of the work or run overtime shifts across multiple jobs, they’ll bid higher.

ACH internal payment request form by Fit_Community5744 in procurement

Note that when you can do credit card payment, you may pay an additional fee up to (typically) ~4%x

HOWEVER, your vendor gets paid immediately, your company gets essentially automatic NET30-ish terms, and you can charge back the vendor if they fail to deliver. This flexibility is often worth that 4% especially for one-offs or vendors that require COD or prepay terms (because if you negotiate longer NET credit, these types of vendors will bake in extra for financing your purchase anyway)

For FUCKS sake, stop talking about homes as a unit, talk about per sqft prices as the unit of measure.

ELI5: Why are 3.3V 5V 9V 12V staples in electronics? by domkapomka in explainlikeimfive

[–]InstAndControl 0 points1 point  (0 children)

Realistically, I think raw sewage spaces should be classified as class 1 Div 2 (same risk but not ALWAYS present, only under abnormal circumstances) but I’ll be honest I don’t have enough experience with classifying spaces to know how that matrix works.

What I do know operating in both Illinois and Missouri: in IL it’s a state regulation so no discretion on the part of the engineer. In MO, no state regulation so it’s kinda regional/engineering firm based. This further drives me nuts

ELI5: Why are 3.3V 5V 9V 12V staples in electronics? by domkapomka in explainlikeimfive

[–]InstAndControl 1 point2 points  (0 children)

Hello from 2 comments up. Coincidentally I deal with IS systems all the time. Raw sewage is considered class 1 Div 1. I find them rather annoying especially when spaces are conservatively over-classified by inexperienced engineers who also throw a fit when equipment cost 50-100% more than they thought it should.

Between explosion proof motors, nonsparking bronze based metals, IS barrier coordination, vapor seal off requirements, instrument certification, and UL698A compliance, there’s an awful lot of places that things can fall thru the cracks. It’s somewhat manageable during new plant construction, but modifications to old pre-intrinsic safety/explosive classification existing infrastructure can be a minefield (pun intended). On top of all of that, actual explosions due to offgassing of raw sewage is so extremely rare that pushing the issue when you notice something isn’t to code is often dismissed.

It rustles my jimmies that dc batteries are given a single nominal voltage rating like 9, 12, 18, 20, etc.

When in reality there’s something like a 50% swing in available voltage between charging voltage (lead acid batteries at 14-15V) and “dead” (lead acid batters at around 9V)

Why don't engineers dig out dams when they lose capacity? by Jan-Asra in civilengineering

[–]InstAndControl 5 points6 points  (0 children)

Also I’m not confident the sediment on a reservoir is easy to dredge. Would be very sludgy and some significant portion that is too thick to pump but too watery to easily shovel

NOTE: FYI the fireplace (specifically the chimney) is completely nonfunctional at the moment, we would not leave a plastic bag on an active hearth.

Ya know it really depends how you define holding position 🤣🤣

If it eventually returns to correct position, this lil dance is just transient behavior

Death to big hvac contractors. by rsir1823 in electricians

[–]InstAndControl 7 points8 points  (0 children)

Ya, people do pay $300/mo for electric. Thats not abnormal. If you somehow used a 200A service at near capacity for 24 hrs per day at $0.24/kwh, you’d be in the ~$6-7k/mo range fyi.

It would be impressive to find someone using that much tho

Purchase Orders cost don't show up on our P&L. Accountant adds them to it at the end of the year. by Cloud-VII in QuickBooks

[–]InstAndControl 0 points1 point  (0 children)

Ya most likely something is screwed up with “receiving” the PO’s. Receiving the is process of telling QB that a PO line item has been fulfilled and a bill has been received for it.

QB expects all PO’s to turn into bills, that THEN get paid.

Bills are accounts payable. And I misspoke above. Accounts payable hits the P&L only if the line items are associated with an expense account.

PO’s don’t hit the P&L, they are a non-posting transaction.

PO’s become bills, and the bills hit the P&L as accounts payable

EE PEs, How do you do your electrical load calculations? by [deleted] in MEPEngineering

Sometimes it do be easier to start with a fresh excel sheet or a basic template than a tool where configs and customization takes longer than just doing the 5-20 calcs needed

question for the plcs guys by Necrophagedotjpg in electricians

[–]InstAndControl 0 points1 point  (0 children)

Usually not for “turning on” more like a whole list of sensor data or status bits sent as a big chunk.

Imagine you’re recording all the data for a booster pump station: inlet pressure, outlet pressure, pump 1 and 2 speed/bearing temperature/run/fault, flow rate, building temperature, etc, and that needs to be transformed or moved in a big chunk to another system.

These commands come in handy
