THEY SAID THEY NEVER LEAVE THE DOOR OPEN.... 

That's right

We don't leave it open, we set it open.

@@ingiford175 on God 🤣🙏🏼😂

You are so right. I am ret. Chemist (hate politics in such) so I watched several hundred videos, especially HVACRs and walked right into the trade. I must confess I was already completely versed from DC through 7200 VAC so just watching furnaces fixed, refrigeration cycle and metering devices, I actually helped seasoned guys when inverter and pulse-width circuit boards were issues diagnose. I scored 98% on Universal 608 and got hired. Addendum: I worked for an established Family HVAC LLC for a year and asked to be a helper for however long I needed. They put me in a van after three months solo and never looked back. COVID was a huge pain but never missed a day.

Yep something didn’t go through the apprenticeship in my state. I had the license hours & basic HVACR schooling I taught myself & old timer refrigeration mechanic help me get my trade license.

Employees will end up tearing them down, especially when they get caught in the carts that they shouldn't be shoving into the coolers in the first place.

@@sparklesparklesparkle6318 Understandable. Two weeks worth of cocaine is probably twice the cost of that curtain.

Haha, we used shrink wrap to pull those to the side. They were a PITA and hurt when they smack you in the face from pushing pallets and racks in and out. Some people would actually cut them after being smacked

Well he gets paid for that too.

@@rdizzy1 Our HVAC supplier carries all the parts for walk ins that others don't have access too. So in my area, the freezer and cooler hinges are still part of my job. We get paid just the same as changing hinges as we do diagnosing a refrigerant related issue.

not quite accurate. it still could be accessible if modem/router(or what ever is in the center of the network) is connected to the internet. Just keep that in mind

@@Grauenwolf You are correct. That address 192.168.50.1 can be used on every LAN in the entire world. So even if that LAN was connected to the WAN, you need to know the address of the WAN to connect through the internet. I like your comparison to a room number. Witness protection breach because they released the fact that the witness was in the kitchen!!!!!

@@mrxions Not true. That requires NAT and port forwarding to be setup up.

@@mrxions I'm afraid you're incorrect. It would require network address translation and the router to be explicitly set up to forward traffic to the LAN address. Even more so, the whole point here is that the URL displays the LAN address which by definition is unroutable -- even if someone would have set up a router that way, it still won't be known to anyone which public address to use. So yes, it's perfectly safe to display LAN addresses in a public video. (i.e. just by connecting a router that has internet connectivity doesn't suddenly make a LAN segment public ;-))

i have to apologise. I didnt know the context. I just replied to comment asuming that the context was "because a device has a LAN adress it cannot be accessible through the internet." I didnt know the question was "is it ok to show a LAN adress in a video"

Must of never worked in a restaurant before, the workers will find a bypass in a day

You'd think the engineers would be smart enough to check the rated operating range of components before picking them! There's plenty of wireless microcontrollers rated for down to -40°C, though that doesn't help when corporate is telling the designers to save every penny they can

@@Connie_cpu - Yeah, you'd think that, wouldn't you? My father is an engineer (retired). They're often told "here, use this prebuilt module that the sales department said would be the best for this job." From listening to him discussing the explosion proof packaging he had to design around electronics, those type of robust components are generally very expensive, and almost never "off the shelf". In a case like this, they'll be using a standardized board, much like you'd find in a bluetooth speaker. - watch some of BigCliveDotCom's disassembly videos, and you'll see a few examples

In supermarkets, I've often walked past and shut doors that didn't close properly, and the person that opened it just walked off.

Without challenging you on your excellent point, what do you say to those dealing with a door opened less than five minutes ago, and thus opaquely frosted?

How long is too long open?

We have alarm at 20 min at some of my client and it reset after every time you close the door

@@SeanReigle I'm sure that can be worked out. Just report at first, and then look to the pattern to set an alarm value. I'd bet the values logged would show a clear cutoff - such as up to 15 minutes to load, or left open for 2 hours+

@@SeanReigle We have similar in the retail chain i work for but its an audio alarm "cold room is open, please close the door" that for is is set at 4 minutes but can be set from 1 to i think 20 minutes and generate logs if you want... how long is too long... well for most situations... a couple of minutes is more than enough.... indicentally the energy savings from doors NOT being open paid for the alarms in a hurry

That’s a really good idea. But unless it’s a drive-thru alarm most people won’t care too much.

Worked at a place with the door alarm. Staff ripped it out one day! 😗😗

@@mikechasse1016 Well you can't serve the ignorance of these people ;-)

The world needs more beeps and buttons so the future children can function for the boss.

He said it on numerous of other videos on why they don’t have the alarms

@@Freonleon well, I haven’t had the time to see them all.

RFC1918 private addresses. You can think of them as dialing an extension number on a phone system - "extension 103" only makes sense inside that building. If you dial it from somewhere different, it won't go to the same place.

Thanks for watching @Bryce Burns

door alarms existed more than 20 years

A lot of the times they'll leave the door open to cool the space or the kitchen area.

Various manufacturers have worked a way around this... driving too few LEDs in a light and driving them near their limit will greatly reduce the life of LED lighting. The other trick is to build the LED lighting into the lighting unit itself so it's not a case of changing a standard bulb, the entire unit has to be replaced.

PLEASE PROP THE DOOR OPEN SO I CAN COME OUT, DEFROST YOUR COIL AND SEND YOU A *HUGE* INVOICE EVERY MONTH. LOVE, YOUR HVAC GUY

You've seen something being given out?

How about a spring delay hinge, one that closes very slow, between 30 seconds and 1 minute? Is there even such a thing?

Time-delay

Because people don't read signs (known fact) and those who want the door to stay open for their own convenience would just think to themselves "I don't care what the sign says". That's how these people think and operate.

10_X_X_X are reserved for LAN, not limited to 10_10_X_X. 192_169_X_X is a public IPv4 address and must *not* be used for internal purposes. If you find anyone doing this, beat them with the IETF/IANA rulebook until they mend their ways. You can get away with using it, of course, but it's a dumb thing to do because things will go badly wrong when systems with these public IP addresses assigned locally try to communicate with a public service that uses one of them. The chances of clashes are low, but I've had it happen once and even had to go nuclear on the administrator who tried to tell me that I didn't know what I was doing, and it didn't matter anyway.

@@nickryan3417 ah, thanks. I'll edit so people don't read my bad info. It's been 20 years since I learned this stuff.

The first "Private" Ip range is 10.0.0.0 through 10.255.255.255 Second is 172.16.0.o through 172.31.255.255 A lot of people who don't live in the networking world professionally forget and or don't know about the 172 range....... The Third is 192.168.0.o through 192.168.255.255 Those 3 ranges are all Private, and non routable. Meaning, they can not be accessed from the internet unless someone does NAT, (Network Address Translation) to make the device available from the internet. Additionally if they do it, and you are on the internet, you will use a different address to access the device, NOT the private address. An easy analogy for an inbound NAT, would be similar to you forwarding your work desk phone, to your cell phone. You call the work phone, and you get forwarded along to the private IP address (the cell phone.) The only part of the analogy that does not quite work, is with the Networking NAT, the cell phone that gets the forwarded call, is not reachable. So you cant call directly, you have to call the desk phone....
