exactly

I'll happily test them for you...

:)

ive actually got a bunch of old text documents with codes in, so will at some point be uploading a megafile to dropbox to circulate among the regulars

I didn't think you would take me seriously!

well if there are unredeemed codes, better they get used

I...*ahem*...I volunteer on testing this dangerous theory. Also, I think people are too lenient when it comes to giveaways. Nothing wrong with low requirements but when a user never posts outside giveaways, you know something is shady there.

It's a little surprising that something doesn't exist already. When I first went looking for trades I half expected to find a community built tool that would require each user to enter the code they were offering, display the content to the intended recipient and then transmit the actual codes once both users confirm the content is as expected. However, what if a scammer can still redeem their own code just as it is transmitted? would there still be enough value in merely checking for valid codes to build the tool? maybe that's why nothing exists - it really needs to be a GOG built tool to be ideal. Not sure if GOG have much incentive to do it, trading is tolerated but is it something GOG view as good for them?

At the very least you can confirm they HAD a code. Better then empty promises and empty trust...

Something is better than nothing :) Even if a tool isn't perfect, being able to screen out some (maybe even a majority?) of the scammers could be appreciated by many GOGers. If anyone has the skill and the willingness to build a tool I can only applaud the effort!

Alright. I've sent a ticket to GoG and we'll see if they would prefer to assist, do their own tool, or do nothing. The only issue i have implementing this solo is trying to confirm redeemed/valid codes while not logged in... (and an external site page pinging on codes won't have a cookie with me logged in)

I'll keep you up to date once i get a reply from them.

Really, I don't think you have cause for complaint if you hadn't redeemed a key in four DAYS much less a month!

of course they could drop a surprise on us and include this function in Galaxy!

Not right away.

Got a reply they are forwarding the message, which doesn't mean much...

As a note i've glanced over the 'redeem game' raw page and noticed it's almost entirely in JavaScript. Doing code checks in this way seems unlikely, for a external server. Although not impossible to get around, it wouldn't be worth my time and there would be too many headaches to consider the options (slow and buggy as they are).

I've started notes regarding the internal MySQL structure to support the game/code trading and an issue of code size comes up. There's 16 Alphanumeric characters. 36 combinations gives a log2 calculation of 5.169925, that multiplied by 16 gives the raw number of codes the system can support before they are all used. The data takes 83 bits to store. This means it will probably just be worked and stored as raw text (rather than get too complex into the reasoning behind it).

Just to go off on a tangent of this, 83 bits is HUGE. If you took say the population of people on earth, got each of them all the games on gog as individual keys (10 billion times 700), that's 7 Trillion keys (about 43bits). Assuming GoG managed to sell that many keys PER SECOND, it would take 34,800 YEARS to exhaust all the keys... Then they just add another 4 characters on and Viola! Now there's 1.6x million more keys than were just exhausted... and to exhaust those would take...

well i'm not going to live to see that day so that isn't an issue :P
