Jigdo - More thoughts

Ver interesting...


Jigdo actually allows you to pick the individual files and form the ISO on your disk...


Great Idea =)


Contrast this with torrents, where the bits are manipulated.



Two different technologies I wonder which would be faster? And what would be the metrics of measure.


Also apparently Jigdo is already used in Debian distros. Good to see the Debian folks produce and leave their marks =)



Also to someone new to using a linux downloader, it might be quite freaky as it is really international, the mirror sites =)

Japan, Russia, Taiwan and many more which I do not recognise =)


Its not the fastest thing on the planet, but its decent =)


Update:

FTP speed versus Torrent essentially, but I suspect with more overheads, as it negotiates for each file.


This opens a whole slew of trust issues I suspect... but you could of course verify the hashes so thats cool.


And it does actually autoverify for you at the end of download, which is cool =)

Not very fast, I should thinik a torrent will still be faster, but only for the latest and most popular torrent.

For older stuff for which peer to peer critical mass is scant, you are probably waay better off with Jigdo, since you are getting FTP speeds.

This may actually solve one of the conundrums of Bittorrent:

Once a file is mostly had by everyone, speed degrades. Unless you live in an utopian world where RIAA and its likes do not hunt ppl down, and even in such a world, would people who have fully downloaded be willing to serve as seed? And if so for how long?

And thats the beauty of it I guess, *all copyright vigilantes rejoice* , and that is jido will not help the usual "bad" downloads, since it is specific to building an ISO. Unless of course people start distributing in ISO, and even then you are talking about people distributing individual files on their servers... kinda flying in the face of Bittorrent.

Oooh but think of Jigdo running on top of a peer to peer.... (which still does'nt help... only in the automated sense which should be achievable without Jigdo ... =P)

Fedora 8 CD ISO !!!

Fedora 8 CD ISO !!!



I have been wanting to try out the Ferdora 8 series for a while.. but as happenstance, my DVD cannot burn...

Well I screwed with the iomega Hotburn settings and must have corrupted the drivers, but that is another story =P

So I am like stuck with CDs even thought I can read DVDs. So this new site is a life saver!





W00T!


The catch?


They are trying a new download technology.

Its supposedly better or less stressful on their servers than torrents???

Hmmm...


Anyway the new download method is jigdo.

And here is the link:
http://spins.fedoraunity.org/unity/fedora-unity-re-spin-f8-20080204

though a little browsing will get you there too


Beware though, this one is still console based, at least the one I am using... and it does require you to be patient.


Not too much automation for deciding what you wish to download, but the download speed is decent, which may be due to my bandwidth =P

and lo!


Running it I realised it is actually wget in disguise then!


this is strange then wget can achieve multiple downloads on the ftp.....


I suspect I missed out something on reading as usual....


I downloaded my version from here :




Here is more on jigdo if it so pleases you to find out more about it.

Gdae.
