The file transfer problem

I've been having file transfer problems ever since I've migrated to Linux because I generally have to send files to people I chat with and those idiots at Yahoo don't want to make a god damn client which works properly on this OS (Linux is not to blame for heaven's sake...).

Over the years I kept finding several web sites and services that helped deal with this situation. However imperfect some may be, I will list as many as I can remember here and further add new ones from comments (if any).

Text / Documents transfers

• Pastebin - Best thing ever.
• Allows unlimited and anonymous plain text sharing.
• Provides syntax highlighting.
• There's also a few more settings you can change like post expiration or visibility, but even without them it's the one and only service I need.
• There is also a Linux program pastebinit which allows sending text files to sites like pastebin (there are more than one obviously) from the command line.
• IdeOne - Similar to Pastebin, but it's made for code snippets.
• It actually compiles and runs the code besides letting you share it.
• It supports about 40 languages ranging from C, Java, Python, Ruby... to obscure languages like Brainf**k and whitespace. Doesn't work with LOLCODE : ( at least not yet.
• Google Docs - Document sharing.
• Keeps track of your documents and allows you to show them to anyone you wish.
• Allows collaboration editing. More than one person may edit the same document at one time.
• As far as I can remember, you can upload random files as well, but I think there's a 1 GB limit.

Image transfers

• Imgur - My personal favorite. 
• It allows unregistered uploads (and gives a deletion link for the first time the image is viewed so you can remove it). 
• You can make unregistered albums (but can only upload one image at a time), and I don't know if you can edit it later on. 
• You can make a free account which keeps track of your images and albums and allows bulk uploads as well.
• There is also a set of free tools and extensions for the site.
• Imageshack - Similar to Imgur, but as far as I know more restrictive for unregistered users. I don't like it that much though.
• Picasa - The Google variant.
• Gives you 1 GB of space for your image albums and gives several features for your albums.

Single files

• Jetbytes - Just select a file and it will generate a one time valid link. One must only send that link to anyone and he/she will start downloading. It's that simple.
• FilesOverMiles - Same as Jetbytes, but the link is valid for more than one download as long as the uploader keeps his browser open.
• [Edit] MegaUpload - Free 1GB uploads.
• I've just discovered how powerful this site can be when asking for pictures from people who have no idea that torrents are.
• It allows free uploads even without an account.
• Bugs you with ads and wait timers (but that's ok sometimes).
• Allows resuming interrupted downloads with a free account.
• Allows organizing files into folders for free accounts.
• Your files will be deleted if not downloaded for 3 months.

Multiple files

• Archive them! - I mean seriously, even when Pidgin transfer works I have to accept each file individually. That's what archiving is for dammit.
• Emails - Good ol' email never let me down.
• Emails are the most basic and brilliant way for sending data.
• The problem: size limits which differ from provider to provider, and is generally 10 or 25 MB.
• Drop.io - The 100 MB dream.
• You can upload any number of files of any type.
• You can preview several of them online.
• You can group, sort, search through and download any number of them.
• You can password drops and have administrator and guest passwords (no users involved).
• You can have any number of 100 MB drops.
• There is also a paid version for more space / drop, but I never bothered to get details.
• Torrents - the master of all file transfers.
• Everyone knows how torrents work, but few people realize how powerful they are and how they can be used for casual transfers. You can obviously send limitless data.
• Torrents require a tracker to work so this might appear as a problem at first, but a couple minutes of googling brought me to http://openbittorrent.com/ a free tracker perfect for casual transfers. Very simple instructions of how to use it are found on their site.

I hope this list might be useful to anyone having problems sending stuff by messenger (not a very reliable service...) and I will update this list as I find new or better ways of sending stuff.
