Re: A reminder about heating, and power strips
It would be nice if circuit breakers were a required rather than optional feature of power strips.

Re: A reminder about heating, and power strips
Every electrician and electronics technician and electrical engineer has studied the theory behind this problem as the most basic introductory subject matter in their professions. It's almost like 1+1 is for mathematicians.

Voltage equals current times resistance (E = IR, Ohm's Law) and power (which translates to heat that has to be dissipated) equals voltage times current (P = EI, easy as pie -- though you will have to scroll down in that link).

In a series circuit, all the resistances are lined up along a single path of current flow. There, the voltage (in reference to zero volts) is different at every resistance -- such a setup can be used as a voltage divider. The current is determined by the total resistance, which is the simple sum of all the resistances. That's not what we are talking about here.

In a parallel circuit (which we are talking about), the voltage across every parallel circuit is the same. The current being drawn is still determined by the total resistance, but that is no longer a simple sum -- if you want to see what that is, either research it yourself or message me, but it ends up being less than the smallest resistance of any parallel branch.

To make it simpler for a non-electrical type to understand, take that same voltage across all parallel branches and apply it to all the different resistances of every branch to determine how much current each and every one of them will draw, and add up all those currents to find out how much current all of them will draw. Then multiply that total current by the voltage to see how many Watts of power (AKA "heat") that will generate.

Now, the more parallel circuits you have, the more current they will draw and the more power (AKA "heat") they will generate and that will need to be dissipated. So you have lots of devices plugged into your power strip and you plug another power strip into that with lots of devices plus another power strip, etc. Doing that, you could easily exceed the power rating of your house wiring or at least of the original powerstrip. Now when you plug in devices designed to draw lots of power because their purpose is to heat up a living space, then you are just asking for trouble.

So Fitchburg ...
Now, the more parallel circuits you have, the more current they will draw and the more power (AKA "heat") they will generate and that will need to be dissipated. So you have lots of devices plugged into your power strip and you plug another power strip into that with lots of devices plus another power strip, etc. Doing that, you could easily exceed the power rating of your house wiring or at least of the original powerstrip. ...

So if you have a basement full of plants with grow lights plugged into power strips, plugged into power strips, plugged into power strips ....

Even though the grow lights themselves (fluorescent) do not draw a lot of power, the accumulated demand creates a potential fire hazard. To say nothing about the damp environment...

That's my thoughts.

Thanks

Bandwidth usage
Apparently I am using 93.38 MB (373.52%) of bandwidth (25.00 MB plan)

When I only have 66 MB (0.27%) Storage Used and I am not actively posting pictures? Do search etc robots cruising the forums cause this?

I know of one (1) picture I have linked recently on this forum (Message 7). I don't need to use these photobucket pictures on other forums, so as far as I can see this one picture is causing 93.38 MB of bandwidth usage for the month.

How can I control this?

Does the [thumb] command use less bandwidth than the [img] command?

Thanks

Re: A reminder about heating, and power strips
Be safe. Avoid extension cords to heaters if you can. Use outdoor extensions if you need one.

Better yet, just put a jumper on.

Re: Bandwidth usage
Bandwith and data maxes are different things.
A 25.00 MB plan would mean you can only download 25MB of data per month. Do you mean 25 Mbps? A max of 25MB of data per month would be worthless so I think you must mean Mbps. For example since I turned on my computer 45 mins ago, my computer has downloaded 113 MB of data and uploaded 9 MB. The Mbps speed is irrelevant to the total data that is downloaded.
Are you on a cell plan or a satellite plan?. Those are practically the only plans that have data caps. If so what is your data cap? It can not be 25 MBs?
For, example I have a 20 Mbps plan, of which real world speed is about 12 Mbps. These days, this does not even qualify as broadband.
https://www.nbcnews.com/...finition-broadband-speeds-n296276
But, as it is a DSL connection, I do not have a data cap. If I was abusing the service, for example downloading movies all day every day, my service provider might throttle my speed. But we would be talking 100's of GB of data for that to happen.

I think the rest of your questions are irrelevant if you are on a standard internet plan. Bandwidth is not something that accumulates. It is the speed data is moving at a particular moment. Unless your plan has a data cap you do not have to worry about the pictures you link to.


Facts don't lie or have an agenda. Facts are just facts

"God did it" is not an argument. It is an excuse for intellectual laziness.

If your viewpoint has merits and facts to back it up why would you have to lie?

This is photobucket, which I have been using to store the images I post on threads here. I am currently well below that limit for stored pictures, that is not the problem.

I think the rest of your questions are irrelevant if you are on a standard internet plan. Bandwidth is not something that accumulates. It is the speed data is moving at a particular moment. Unless your plan has a data cap you do not have to worry about the pictures you link to.

Except this is where the problem with photobucket is involved: they say my bandwidth use to view the pictures is way over their plan limit.

I don't understand where this bandwidth usage is coming from, it's like the pictures are constantly being viewed over and over and over.

and I don't have any control over it.

Thanks

Ah, makes sense.

Remember the limit they are talking about is the sum of every access from every viewer. So if I look at it and you look at it the use is 2x. If three others look at it the use is 5x. And if we go back to check a detail it is 10x.

okay, but I am being punished (pictures blurred out) for something I have no control over.

and it's probably not even the picture being looked at but the thread being loaded for people to see the latest posts with nothing to do with the picture.

that's not right.

This has only cropped up since I paid for their basic plan. It looks like a sucker plan imho.

Re: Bandwidth usage: photobucket
Ah yes the photobucket bandwidth issue. Sorry I missed that part the first time. It is a well known problem. There is nothing you can do about it. They are just trying to monetize there service. The changed terms of service a couple years ago. I think their bandwidth cutoff is pretty low. There must be other sites that are a bit more liberal in allowing the viewing of stored images. If they are going to charge at such a low level of actual use then storing images there is cost prohibitive and not worth it.

You would have to store images of such low quality that it would not be worth the effort to store there.

Definitions
Bandwidth vs Size

The bandwidth is in volume per time period. What you are describing is total size. So I have a 30 MB/second bandwidth cap on my internet service (for downloads) but I have hundreds (actually unlimited) capacity in total bytes movable up or down.
Jar, describes accessing a photo 2 or 5 or 10x. The only thing that has to do with bandwidth is how fast a 1 meg foto will move up or down.
I'd say in general that you can NOT exceed your bandwidth. It is set by the server. But you can, by moving the picture many many times exceed your allowable amount of data moved.

Re: Definitions
Here is photobucket's bullshit explanation. It actually has nothing to do with bandwidth.

quote:
Storage vs. Bandwidth (What's The Difference?)

Your storage is related to how many images/videos you are uploading to your Photobucket account.

Your account bandwidth, or linking bandwidth, gauges how many times someone has viewed your linked image on a 3rd party site.

To further explain, bandwidth is a measure of the resources used to serve (display) media from your Photobucket account to 3rd party sites (like blogs, forums, etc). The size of the image or video will increase the amount of bandwidth you use when you link out to other sites.

Direct views of your images/videos on Photobucket does not use any bandwidth. Bandwidth is only used when the image is posted outside of Photobucket, which we define this as 3rd party hosting.

Learn more about 3rd party hosting here.

Examples of bandwidth usage:

-Lets say you have 100 photos that are 1MB in size each, and you are linking every single one of them out to your blog/website. 100 images at 1MB in size means that you are linking out just under 100MBs in data size for all those images. Those photos would need to be viewed 100 times a piece to reach 10GB bandwidth.

-If you only linked out 10 photos that are 1MB in size, those 10 photo would need to be viewed over 10,000 times before you would reach 10GB bandwidth.

-If you had 10 videos on your blog/website that were 100MBs in size, that would equal out to just under 1GB in file size. If those videos were viewed 100 times total, you would reach 10GB bandwidth.

Re: Bandwidth usage: photobucket
Move to imgur. No such restrictions, and at the moment there isn't even the option to pay for an account. Not quite sure what their business model is, but it's useful for now at least,

Re: Bandwidth usage: photobucket - caved
Move to imgur.

I think I tried imgur and had some issues with it.

Doesn't matter at this point, I caved and upgraded to unlimited bandwidth.

Also I already have most of my images on photobucket

Enjoy
