jQuery Coverflow

My jQuery Coverflow….

So I’ve been hunting round for a coverflow plugin for jQuery.

Google search turned up both Blarnee Demo (or Blarnee Blog Post) and Paul Bakaus, both of which are quite good but don’t advise much on the use or implementation of.

Both of which are demos, using parts of jQuery and the jQuery UI, or elements of Canvas (which has been throwing odd errors in my firebug)

The second still being sat in the labs part of the UI svn, and not been touched for 6 months.

So further hunting found me, content flow, which looks quite good, but I couldn’t get it to implement properly or do quite what I wanted too, without throwing lots of errors and not working.

So, I thought about it for a while and heres the first result.

Video done on Mac Quicktime Player, (screen recording), web deploying soon…

I’ve used the jCarousel Plugin, which I already use on LSRfm.com for the LSRfm.com Twitter Rotator.

And using its callback functions and elements of jQuery’s animate library. I’ve created this iTunes/Apple Coverflow effect, still some work to do, and make it nice and configurable, so others can easily implement it, perhaps even make it and extension to jCarousel…

So a future blog post will describe the Javascript I used, and how to implement it.

Uploading LARGE files to Webservers

A quick run thru some of the jQuery file Upload options I’ve tried.

So, I have my server set up to accept large files, since I have built a nice new podcast submission system for LSRfm.com on the machine called LSR-LOCAL.

Now I decided that its all well and good trying to make it work/look nice, in terms of waiting for uploading for files and little feedback, we are dealing with the lesser tech orientated here.

So since I already have jQuery on the website, I started looking there.

The first one I found jcUpload looks rather good, and then I saw the multi file upload aspect of it and thought I can use that to do multi file transfers for LSRfm.com Production to bounce files around each other securely, rather than relying on email or rapidshare.

However that fails on files over 5Mb.

Went on a hunt around for general flash uploaders, since I read somewhere flash handles up to 100Mb or so nicely (I think it was on jcUpload’s website), I found SWFupload, however I couldn’t get it to configure properly.

During my initial search for jQuery plugins I found uploadify, which looked quite good, but got distracted by jcUpload. Uploadify essentially just kicks ass.

And now I have a nice little production file sharer, that will handle multi file uploads, and look good in the process. Since it has a nice progress bar, and handles queueing nicely without have to have a shed load of configuration or extra files like SWFupload.

I did look at AJAX-Upload but decided I’d stick with the flash solution, since the AJAX solution didn’t have a upload progress bar.

Now that I’ve finished the nice uploader for production I can go back to the podcast uploader and add the flash uploader.

Of course with suitable javascript fail support.
Also need to figure out how to nicely remove a file element if the flash does the upload…. Probably a separate form but that will require a hefty recode of a lot of code that already works, but it will look and work nicer in the long run.

Long Time Since I blogged

A General Update….

Again, its been a while. Things have been pretty busy.

Currently I just fixed the LSRfm.com Podcasts, they were downloading a minute or two of audio the PHP was dying, FAST CGI php5 was being ghey.

So after a quick chat with Dreamhost over live chat, my script now rather than munch the file, just passes it off to a http location, less of a memory muncher too.

SRAchart is its usual self, tho we did get a full house of Charts last week, (well near enough), Ellie Goulding and Owl City are dominating, and Glee Started Charting too.

(Yes I am a Glee Fan)

Handed in the Motion Graphics Brief.

So Uni Wise I just need to sit down and code code code, both for Project 2 (ala 360gaming.net enhancements), and start planning and researching what I need for project 2.

And start writing an essay for Futures and Strategies, fun times.

I’ve not had any spare time to play Halo, tho the Reach Beta has been announced! Hurrah!

Now I must get back to coding stuff for LSRfm.com fixed the Jukebox, now to do the music db, tho I do have a nice IRC bot sat in the new LSRfm.com Chatbox

Also <3 jQuery....

Testing a LSRfm.com Podcast Player Embed

Testing embedding LSRfm.com Podcasts in a non LSRfm.com Place, with a nice Player

Testing embedding LSRfm.com Podcasts in a non LSRfm.com Place, with a nice Player

So heres all the LSRfm.com Podcasts, might take a while to load, as the big feed of all podcasts is rather, rather big.

Pretty nifty, Longtail Videos, player just munches on the LSRfm.com Podcast Feed, I had to add media:thumbnail for the images, but that is useful anyway.

Mac Fun and Connecting to LSRfm.com!

SSH Fun, with my New Mac Book Pro, and Connecting to Office Stuff From Home Stuff.

So, I’m sat at home, having finished work last night, running Fruity Single handedly (the other tech broke his elbow before coming to work, and got sent to A&E bout 1am).

And then sleeping, (hmm sleep)

I find the need to connect to my FreeBSD VM, which is running on my Vista Laptop, which is in the LSRfm.com Office.

Its worth noting that the FreeBSD VM is running its networking as a NAT, so has its own IP address, so the Vista Laptop as a machine has two IP’s.

Standard SSH Tunnelling for the win!

ssh -p <open external port> -f bcarlyon@<lsr office domain> -L 1313:<internal IP of the VM>:22 -N && ssh -p 1313 bcarlyon@127.0.0.1 && kill `ps aux | grep <lsr office domain> | grep -v grep | awk ‘{print $2}’`

Breaking the command down.

Open the tunnel to the office (I like using 1313 and upwards for local ports, 13 is my lucky number).

-p specifys a port, as @katie_server, the machine I am SSH-ing to initally is port forwarded from the LSRfm.com Firewall.

-L sets up the local port

-N executes no command and puts that SSH session into the background.

Then open a ssh session thru that local port

When I exit the SSH session, the grep command kills the Tunnel, but only ssh commands for the lsr office domain.

grep -v grep makes sure that the grep command is exculced from being killed.

I discovered that the awk ‘{print $2}’ was outputting all the matches and thus kill killed them all which is a bonus, see next.

So I decided to setup Foxy Proxy on Firefox, so that I can route all my network traffic that match a lsr office computer, in this case http://192.168.0.*

So my Firefox now uses normal Internet unless accessing a LSRLocal Ip Address, at which points it routes it thru the socks proxy.

That socks proxy being a SSH tunnel to LSR office:

ssh – p <external port> -f bcarlyon@<lsr office domain> -D 1314 -C -N

-D sets up a dynamic, routes all traffic that goes thru 1314 to its relevant port on the outside or internal internet.

So if I wasn’t using FoxyProxy patterns and was routing all my network traffic in Firefox thru the Socks Proxy, then I can access the whole of the internet thru the tunnel, rather than use -L for a local/specific computer.

-D can be used with PuTTY, say if you wanted to listen to Pandora in the UK and happen to have SSH access to a server in america, or if you wanted to use IRN, which is IP Locked, in LSRfm.com’s case to the LSR office.

So now by alias-ed command for my mac, called freebsdvmnet reads:

ssh -p <ext. port> -f bcarlyon@<lsr dom> -L 1313:<VM IP>:22 -N &&
ssh -p <ext. port> -f bcarlyon@<lsr dom> -D 1314 -C -N &&
ssh -p <ext. port> -f bcarlyon@<lsr dom> -L 1315:<VM IP>:80 -N &&
ssh -p 1313 bcarlyon@127.0.0.1 && kill `ps aux | grep <lsr dom> | grep -v grep | awk ‘{print $2}’`

So,

Open ssh tunnel, to LSRfm.com, thru Katie, into FreeBSDvm (running on Vista Top (Hannah).

Open ssh tunnel for internet access

Open specific Tunnel for FreeBSDvm

Open SSH session thru tunnel to FreeBSDvm

KIll it all, when I exit the SSH session thru the Tunnel.

Given my FoxyProxy setup, the Specific Port 80 Tunnel to the FreeBSDvm is not needed. (I discovered FoxyProxy Patten Matching after writing the command).

So after all this I thought about connecting to the LSR File Server (lsr-fs) thru the tunnel. Initially trying a standard SSH tunnel on port 139, I find that smb://localhost:port/share/ the use of localhost is disabled in current OSX.

Brief Google Later: http://blog.newsyland.com/mac-os-x/leopard-broke-smb-tunneling

Choices Choices.

sudo ifconfig lo0 alias 127.0.0.2 up

Seems easiest, but I find myself using, the main instructions.

Create a ssh tunnel overwriting port 139, then smb://localhost works fine, (but seriously why disable the localhost loop back in the first place)

sudo ssh -p <Ext IP> -f bcarlyon@<lsr dom> -L 139:127.0.0.1:139 -N

The Blog Advises routing 445 too.

Both are privileged ports so need Sudo.

So some terminal use as directed by Newsyland Blog = Win

So that is what I’ve done this morning, some ssh fun and accessing the File Server as if I was in the office.

Next to see if it works on Windows, this is gonna be useful for general use, (and stopping my Apache server needing .htaccess Rules to stop people accessing it) and for Student Radio External Broadcasts!

AND YES I STILL NEED TO FIX MY BLOG STYLE!!!!
