Well, congratulations ! I look forward to reading the CP article.
cheers, Bill

Ahem.. about that... mmmm... arguably it was in the back of my mind though! 
Will take a while... currently doing the serialization reader... it doesn't work yet!

It doesn't need to be a serial; just one article will do.

each side can see the other side's IP in the packet header
but if we run for example tracert codeproject.com we see that a packet goes through a number of gateways between the client and the server .Isn't it supossed that each gateway changes the last gateway's IP address with its own so it can get the packet back ?
if it is so then how codeproject see my IP and not the IP of the last place the packet went through ?
thanks

In any TCP/IP connection, the client's originating IP address is known to the server so they can return a response. You can spoof your IP but you won't receive any data back. The originating IP can often be the outside router IP. The trace you did merely shows the various hosts in the route from client to server. The originating IP is still transferred for the reason mentioned above. Hope this helps.

It's like a Postal Letter right Nish? The "From" and "To" is always there on the covers, unchanged. No matter how many intermediate stops it goes through.

An excellent example of layered protocols. IP, the lower layer, handles the node-to-node messages, as your tracert shows. But a couple of levels higher, the http headers convey the endpoint IP addresses required for end-to-end intelligence. Something like Wireshark will pull the packets apart for you, if you're interested.

Intelligence? http is usually layered on top of tcp, which is the part that is handling all the intelligent stuff. Http on the other hand used to be really, really simple[^], but that's changing[^] ...
Both the source and destination addresses are part of the tcp checksum header[^] ...

Http is almost an "application" of network protocols beneath.

If they don't know your IP address, they can't reply by sending pages to you, and you've broken the Internet.
You really shouldn't do that. Mummy will be annoyed.

So I'm now working on my old desktop PC[^].
It turns out to be a sloooooow machine... What happened!?
I've used this for years without problems, but I've barely used it for a good year and it takes about four hours to install some updates (52, about 400 mb) and another four hours to install Visual Studio 2015 CE 
It hangs regularly, just doing nothing and then suddenly doing that thing I clicked on seconds ago.
Sometimes even my music just goes like "brrrrr" for about half a second because somehow my computer can't process any more stuff... IT'S NEVER DONE THAT! 
Perhaps I should look into upgrading some hardware or even buying something new...

Did you take the back off and give it a good dusting, push everything into the sockets, check for foreign objects? Run a disk check, memory check, check check?
I am not a number. I am a ... no, wait!

Yeah, it wasn't very dusty and the hardware was tightly secured into the sockets.

Yep, it seemed SQL Server was running all kinds of stuff that I never use, but installed once to play around with. Other than that no problems though.
I did a clean install about two years back. Maybe I should do that again... I've got most files backed up anyway.
If it's still slow after that it's clearly the hardware that's the problem.
First time you're giving me actual good advice by the way, thanks.
I'd thank you with an awesome song, but we all know how that's going to end

When a horse gets used to cantering and galloping, but then you dump it in a field to do nothing but graze for a year, everything about it weakens a little.
Given that you installed a fair number of updates (including, I presume, some cumulative ones), I'd give it a couple of cold reboots, just to make sure that everything is cleared out.
If you have Java installed, completely disable their update checker. If that thing finds an update, it seems to slow everything down until you either apply the update or kill the damned thing (I ended up renaming the .exe -- belt & braces, you know)

Gave it a couple of reboots and updated everything that needed updating.
It does seem to be a little faster (but it was really veeeeeeery slooooooow).

Now why would you do that to a perfectly good working machine?

With that logic we'd still be on Win 95.
Wait... I just got an idea[^]

They explained it at build.
As the PC grows older, the Windows registry gets more momentous and everything get slow.
Problem they are working on with Windows 10.
UWP don't use the registry no more!
Dunno about other apps though...

The computer was freshly installed about two years ago.
Little usage since then.
And I cleaned out the registry using CCleaner.
Still slow.

I recently bit the bullet and replaced my hard drive (actually I was forced to as the old one failed) I bought a (£70) SSD and installed everything I really need from fresh - it took a few days to straighten it all out what with updates etc - I even went Win 10, why not? All seems to be working fine as before except a lot faster! PS I also gave it a good clean out, the desktop is kept at floor level and sure does accumulate dust inside - I took off the CPU fan to clean it as the heatsink was literally solid with dust...

I had almost the exact same experience. The old HDD never failed, I just ran out of space on the system partition. Anyway, it was a great excuse to finally get a SSD especially since the price to capacity ratio is now reasonable. ($200/480GB for mine) I also went with 10 and really like it so far.
As for the dust, originally when I rebuilt, I just did a light dusting. Not long after getting 10 up and running, I tried out Minecraft, liked it, and bought it. The problem was after 10 minutes or so of playing, the system would just shut down. My suspicion of overheating was confirmed when I installed a hardware monitor that showed CPU temps of 270F! A thorough cleaning did the trick. The temps now never break 150F and it's much quieter! It's amazing how over the years, you just get used to the fan noise.
