Dear Colleagues, 
I've got a question for you: Is it really allowed to develop and use various online applications run on the client PC that perform real-time scheduled downloads of the content from http://www.codeproject.com/ web site with an http-client. For example, an application that uses timer to launch the process of the CodeProject's main page contents downloading every 60 seconds. This is basically similar to using a so-called CodeProject's API tools to build an application that perform the data analysis obtained from the CP's web-site.
Particularly, I'd like to find out if the following will actually mean that by using such application I'm purposely flooding the CP's web site, creating burden traffic to the CP's web servers ??? 
Anyway, if using such real-time web-client applications is unwanted or not permitted, just let me know and I will simply not create and use it.
You know, at this time, I'm working on the windows 7 gadget will perform the notification of the featured and latest articles announced on the CP's main page. Actually, the following gadget will performs xml-http Ajax requests timely within each 60 seconds to download the CP's main page and retrieve the data on the CP's featured articles currently shown to its readers.
Also, soon, I'm going to write an article in which I will discuss about the gadget's implementation and upload the specific code to the article's web page.

You should be asking the system admins for permission to do this.
|

Thanks for your reply. If the specific admins permission is required, I'd better not to develop and use such web applications. I'm sorry for giving this question.
|
|

|

I am not saying that you are not allowed to do it. Just that you should ask the right people: the site administrators, not the visitors.
|
|
|
|
|
All right, I will contact and ask them just for my inquiry and interest.

Raddevus, thanks a lot for your comment and guidance.

Hopefully that is correct since I am answering in an unofficial capacity.
Please refer to all admin comments in relation to exactly what you should do.
thanks

No thanks. Because as just I've already explained, I'm not going to request any permissions from the admins. Instead, I will simply not to implement and use such unwanted harmful application.
Also, by navigating CP's web site I found the number of articles containing code implementing similar applications including offline articles editors, statistics and the CodeProject API. But, the most of them are not currently active due to security policy restrictions applied. Since then, I will not be implementing such things I've described the post with my question.

|
|
|
|
And yes, you're right for sure. We'd better avoid inventing such things I've had plans to implement and announce.

You can post in the CP API forum, CodeProject API Discussion Boards[^].

I will probably move the post with my question to the specific forum you've recalled.
Thanks for your post.

Hurry up with your Windows 7 gadget before this old version gets retired some days.

Okay, I will make it as fast as I can. When I was writing my question posted, I didn't expect that there would be so much interest to the question I've given in my post. 
P.S. I appreciate to everyone responding my question. Thanks a lot.

It is lack of imagination or any technical difficulty?
Ability to plug an adapter pin either ways is simply a natural comfort.
Particularly when you are trying to do it in low light/dark.
For that matter , even the tradition USB Port comes with this "side" requirement. I always put the wrong side first and turn it to right side. Just wondering couldn't the hardware engineers design a port that could be plugged without worrying about the sides?
Now USB Type-C does it, that does it. But why so late? & Why still USB-A hasn't evolved?
Sounds like an alien plan to frustrate the humans on daily basis. hehe

Needs more pins is why.
USB is a four pin system: ground, +5V, Data+, and Data-
If you got it the wrong way round, it could cause damage.
If you look at the pinout for USBC: USB type C Mod time![^] it's a lot more connections, and they are repeated so it doesn't matter which way up the connector is. That's a lot more expensive in terms of connector manufacturing (for both male and female halves) so the natural inclination is to go for a cheaper connector and call it "backwards compatability".

Since when does reversing VCC and GND have any effect? A cheap and simple 7805 voltage regulator can take that. It may get close to the melting point, but it usually survives and still works afterwards.
|
|
|
|
|
No need for a 7805, a diode will do that job. The point is the connection has to work whichever way its plugged in, otherwise a reversible connector is pointless.
|
|

|

Oh, I know. I was referring to an incident where I was building a new power supply for an older computer and accidentally reversed +5V and GND on the main power supply on the computer. The 7805 did a great job in protecting the computer from damage. It got so hot that the solder started to melt, but it still works.
Reversible connectors are a waste if there are too many pins involved. For USB this may be prctical, but on larger connectors I always found it better to ground unneeded pins and also placed them in such a way that they were inbetween two signals that are likely to interfere with each other.

OG nailed it earlier: it's all about cost.
Sure USB-A a has only 4 pins but making it reversible would need double that (I know could be done with less using the right components but again they cost money too).
Even though talking less than a cent for reversible USB-A, but times a few million pieces starts to eat into the CEO's bonus.

It was more of an accident that made the 7805 the only thing that stood between a computer and a reversed main power supply. It would have been quite acceptable if the 7805 had died, but protected the computer. It took me only one or two seconds to get what was happening and cut power, but in that time the 7805 got so hot that the solder started to melt.
But everything went well. The 7805 and the computer were both ok.

You want us to spend $x million dollars/year to protect against an extremely rare manufacturing defect by a 3rd party and reduce the volume we have available to cram battery into our devices!?!!
You're fired, the money we save by not doing your crazy idea will buy a solid gold toilet for the executive wash room, not paying your salary will let us also install a solid gold door nob.
And thus when a crappy factory does mismanufacture a reversed polarity cable, it does blow up everything it gets plugged into[^].
