so all the newbies here have read Fefe's blog and blindly believe everything he writes? did you guys even take a look at the site or the source code at all? i don't think so....

bitp.it was designed as a background script that the user gets no knowledge of.

seriously....did you open the site even once? On bitp.it you see a live response of how many hashes per second your machine is calculating(with about 30% CPU usage)....how is this "background"? of course users can get a feedback and see there is a miner running. But this is up to the webmasters and not up to bitp.it. The script clearly allows user interaction.

Not only do you waste the energy of YOUR users for YOUR benefit without their consent.

ah, you mean like all the other scripts that run in background without user notice and their consent? like google analytics? doubleclick? INFOnline? adsense? clicktrack? facebook tracker?
The CPU usage of the JS Miner is adjustable...it is all up to the webmaster who uses it on his site but the author of the script can't be blamed for any of your points.

IMHO the JS Miner is a very good (tho short term) alternative to annoying ads. the "donate cpu time" is a great idea to support a site. Of course the user should know that there is a miner running (little symbol,live response, something like that) but don't listen to the idiots who read about it on some blog and don't even seem to know what they are talking about. i know this is my first post in this forum, but i'm not new to bitcoins....i'm just annoyed by the "malware" screamers.

@1bitc0inplz:
for now the JSMiner is really great idea for news papers,blogs and forums, but i have to admit that i doubt the long term evolution of the idea :-/
since mining will get harder and harder, at some point it will stop being profitable and start being useless...unless the user base on the website where a miner is running is constantly growing and growing

It can be easily implemented that there is NO UI shown to the user in any way. If the reference implementation has an UI - fine! The page linked on fefe had none. In fact, It didn't even MENTION Bitcoin! Unless you were actively looking where that huge drain of ressources is coming from, you would have no idea what's going on on that site.

Also JS mining will nearly always be profitable (at least if you think that people won't notice it and thus not be drawn away from your site) as you don't have any costs at all besides a few Bytes of traffic.

Yes, the profit won't cover website costs eventually, but it will still give you some Satoshis for free.

There's another mining script out there that on one hand does far more Hashes per second and also uses all 4 cores on my CPU. This one here just seems to be poorly done, but I expect the worst!
