Babak's dashboard

when I click on my tags (bold) it gives me this error: 500 Application error

doesn't for the tags that aren't bolded

ok, would someone please explain in simple terms how much storage I can have with wuala?

I've read this:

http://wua.la/en/storage/trade

but then what is this thing about "atleast 10% of the limit"?

I just want to know how much storage I can have, is there a way for me to calculate or estimate this? is there a formula? an equation? an algorithm? quantum mechanics? string theory? halp.

also, does "locally stored data" refer to data that other people have stored on my HD or data that I have uploaded and stored on wuala's p2p cloud?

thank you!!

curious if wuala can or already does use this:

thanks

I was uploading a regularly-available game patch, almost 300mb worth, and I'm surprised that the status icon turned into a green check after mere seconds. And I don't think it's uploading the file at all in my computer. I checked the web interface and indeed the file is there, and am able to download through the web even.

Is this some kind of voodoo magic or am I right in saying that if other Dropbox users have the 'exact same file' as you, it would merely use the file already in the cloud?

Yes Alvin,

DropBox is a single instance file store.

That's certainly interesting, although I can only imagine how they do it.

Maybe it's like this, the local Dropbox client in my computer making CRC/hash check thingies to the file, and then uploading that info to the cloud. If there is an exact match of the file elsewhere in Dropbox, it would not upload the local file anymore and merely refer to that file already online in the cloud. If the file is deemed completely unique, it would be uploaded as normal.

Very useful, it saved me valuable time.

Yes I imagine the process would be cool to know. A standard 32 bit crc is way too small a range of possibilities to use in this case, different data WILL generate the same crc. CRCs are good for network error detection though because the likelyhood that noise on the network corrupted your data and the crc in such a way that they still match is incredibly small, and the chance of either getting changed alone in such a way that they still match extremely unlikely too. But with 32 bits there are only 4.295 billion combinations. Most hashing methods are considerably more complex than a simple crc, and they are using sha256. IPv6 using 128 binary bits yields something like 3.7x10^34 possible combinations, I shudder to think how many you get with SHA256.

Hi Michael!

Look into the forum. They already told which hash system they are using. The possibility of a similar code for different files is - according to their statement - extremly low.

Hey Michael V.

I know they are using sha256, and my post includes that, but that is just the hash. Their database backend would be very interesting to look at, it has to track the hashes for the files, the user accounts where the file exists, etc. It is the whole process that interests me, not just the individual pieces.

I'd like to be able to edit the widget's look, size, and styling. For example, remove the mention of how many files have been uploaded and what capacity has been used.

"0 file added, o of 100 MB used"
under the add button and cell

So... the amount of space available for me to use when I'm "trading" depends on not just how much I'm "active", not just how much of my HD I'm sharing... but how much "stuff" is actually stored by others on my HD?

So when, for whatever reason, "they" use less... I'm going to find myself in deep doo-doo.

Imagine I've got enough on my HD to upload and backup 10 GB of data. Let's then assume for whatever reason, that all of a sudden, 90% of my allocated space to wuala is emptied and only 10% of it is now used for backing up someone else's file fragments.

Then wuala goes ahead and erases my files because my capacity is now lower than 10 GB?

wtf?

why do RSS feeds have an pressflip login at the top?

so... does it?
