Why would I like to use this? Have you ever been out bid in an EBay auction only to seconds before the auction only to learn that someone else was interested in the auction and bid one dollar more than your maximum unbeknownst to you? Well, here you have a `backup tool' in which you can make reasonable bid on EBay (as you should) and a snipe bid and then you can avoid that 1 dollar more bid that will cause you to loose the auction. I would recommend the JBidwatcher for a nice GUI experience. JBidwatcher does a similar thing, though the difference here is that this can be easily ran on a server, for example in a crontab, in a set-and-forget point of view. Treating auctioning as an arms race of who has the faster script doesn't really improve things any. Their system can be improved to help remove this last minute auction sniping advantage, and this should be done. This is a proof of concept and really I dislike the system EBay has now. If you have <20 items, don't worry about JBidwatcher's updates stepping on snipes.Out of getting real tired of all my auctions being sniped in the last 10 seconds I started this project of an open source auction sniper. " Tabs are for display purposes all 'active' auctions are updated regularly, regardless of tab, so moving stuff out of 'current' doesn't change their updating schedule. If you think they're conflicting in their use of network activity, it's worth keeping in mind that JBidwatcher's brief item updates don't hold a candle to torrent data streams. " JBidwatcher Priorities " Updates and snipes run on different threads they can both be active at once. Folks have tried to make it 'blend' with bandwidth caps, etc., but it's not the way the protocol was designed to work. " It may not be your problem, but the BitTorrent protocol is not designed to 'blend in', it's designed to maximize bandwidth usage, and distribute delivery of data very efficiently. It also matters a LOT for the time sync operation which makes sure JBidwatcher has a good idea of what eBay's official time is, compared to your computer's clock. This matters for login, and placing the actual snipe. " The other problem is latency with all the traffic being generated, the operating system needs to inject the JBidwatcher request packets into the stream, such that they don't collide with any other packets being sent/received, and then has to process the return responses from eBay. It's been almost a year since I last torrented anything, and I still get pings on those ports. I often wish I could block traffic at the OTHER end of my DSL connection, so those stopped using my bandwidth. If you haven't set a max, it'll flood your network card/DSL, and 'll be hard to get traffic through that.) " Worse, in my experience, once you've run a torrent client/Vuze/Azureus, especially as a seed, your IP address is in torrent files all over the place and even if you're not running a torrent anymore you'll be getting random attempts to connect to your torrent ports. 5MB/s (bytes), and (as I recall) Vuze measures in K/s (K-bytes, not bits), so if you have your bandwidth usage max set to download at 100K/s then you have an effective 400K/s link. (So if you have 5Mbps (bits), that's an effective. You'll get a bit more overhead, from other clients trying to connect and being turned away, but you can effectively treat your pipe as having that much less bandwidth. If you have limited your up/down usage, then the torrent app will try to saturate that much usage. On a home connection, unless you've drastically limited your up/down bandwidth, it'll definitely slow down JBidwatcher's ability to communicate to eBay. I know this because I did it once at work, accidentally. The number of packets, and the size of those packets, sent and received by a torrent program are sufficient to saturate a small internet company's Internet pipe. To quote Morgan Schweers' analysis () on why it's not even enough to temporarily completely cease torrent activity to facilitate a snipe: " Torrents " Torrent activity will definitely cause problems for sniping. Has anybody here managed to reliably snipe whilst seeding torrents ? I was most grieved to have to give up running Vuze on my PC because all the extra traffic it generated caused JBidwatcher (no web GUI either FTR) to snipe far too late where it would have otherwise won me the item - not tightly-timed ones, I might add, but default-set for -30s. Snipes versus Torrents Slightly off topic but a reality check against likely demand is the practicality of sniping for those who (like me) want to continue doing their bit for the torrent community.
