,/` 100% Ubuntu Linux /`. Remote Computing I redid this, see the newer video: SSH + VNC.. This one will remain for reference.. In this tutorial I'll show you ( when I can get it to work :^| ) how to 0. Intro to ssh, or secure shell, which is not really a shell per se, but a highly encrypted "telnet" app with tunneling capabilities, that permit you to route multiple services over a single encrypted connection. 1. setup ssh server (just install ssh from synaptic). 2. connect to the ssh server (just "ssh name@server"). 3. how to use X Windows over SSH, without vnc (below). 4. how to transfer files over ssh, using sftp. VNC - a tool that permits you to connect to any machine remotely, regardless of host operating system, beit windows, mac or linux.. By simply polling and copying screen changes, compressing and sending to a client program that displays and permits one to remotely control applications on the remote machine using a variety of VNC clients. Note, some VNC client programs permit sessions to be recorded and converted to flash files, I will not cover this, but I noticed a number of programs in the synaptic package manager that claim to do this. Anyhow this part will cover 1. how to install vnc server. 2. connect to the server over a web browser. 3. how to connect to vnc with an alternate client. VNC + SSH Tunneling - utilizing a feature in ssh called "tunneling" we can take a remote service and create a proxy service on our local machine that is actually a portal to the remote machines service. In this case, use VNC securely through a SSH session to a remote computer that may be behind a firewall, permitting that there is only one port into the firewall from the outside: an ssh server. Or to connect out of a firewall to a remote computer, say your home desktop, so you can say do something like play GuildWars from work during your lunch hour ( I was able to do this, over my own network, but there is some update issues). 1. show you how to create a SSH tunnel. 2. connect to remote computers VNC "webserver" through that "secure" tunnel. For the record, I'm typing this from my laptop, near the kitchen, so I can eat, drink, watch miro, and upload this video, from my desktop machine, which I do my tutorials on, near the rooms where people are sleeping, so I can avoid waking them up while I do this.

.`100% Ubuntu Linux/`. Silent Tutorial on Linux Now I know what you are thinking, why silent? I got my audio working, just was heading off to church and didn't want to reveal what I was doing, is the truth. It's hated that in the last minute I am doing something, so rather than give off that scent, I decided to keep things quiet. I'll do an audio based tutorial on blender at some point. I'm remembering more about blender that I had forgotten, like how to set parameters on clips and things like how to use render layers and such. The opening animation to this will probably be what I will start with. The warning message is a mesh made from some text object, with a set of lights both with RGB ipo curves (animation curves) and an energy curve for the light.. I spent most of the time trying to sync up these.. I've thought why blender doesn't easily permit people to associate one curve with multiple objects and use math to modify the value.. It's probably possible with python, I just don't know enough.. But I had recalled that I could copy curves from one attribute to another using some special icons.. Anyway the animation of the text is reuseable, the text is curve based (converted from a text object), but the animation is mostly just translation (moving, no rotation or scale) and two lattice objects, one is linked to the other by the object data, only scaled nagitvely, so I only need to animate one's object data.. They are animated with basic vertex keying but probably should have used relative vertex keying (??). I first animated the text then parented the text to the lattices.. Then perfected the timing.. Not perfect enough but suitable.. AS for this tutorial.. I just introduce you to a bit of command line Linux.. And reveal some key ideas about why Unix/Linux is the way it is.. Best thing to do is google for "Linux Commands" or "Linux Terminal" or "Linux Shell".. Also all Unix like operating systems including Linux offer support for man pages. They predate pdf manuals and though software is distributed without the manuals usually, you can download them with Ubuntu's package manager, which will automatically install them. To find out how to get man pages, check the video. First part of a man page is the usage, followed by options (always preceded by hyphens), then a more elaborate description of the command is given below, with related commands at the very bottom. Man pages need not only be about commands, but cover things like how to compile programs, how to use programs, and whatever seems useful to those that maintain the software. One command I didn't mention in the tutorial is the "which" command, which tells you the path to the command from the root folder.. Like "which man" will reveal the location of the "man" commands program file. Some commands like "ls" may not have a command, but be associated with the shell. A shell is a program that intercedes between you and the operating system, when you enter in commands, the shell determines if the commands are local to it or located in the machine, it also sets up relationships like data piping and handles tab completion and such.

If you’re a user of the popular Facebook networking site then you may have heard about the latest Koobface Facebook virus and the problems it’s causing via a link to a video that asks you to update and installs something nasty. ..

Latest Facebook Koobface Virus: Spawned by an earlier attack …

Adobe has announced that their membership in the Linux Foundation. This comes on the heels of the Alpha release of Adobe Air for Linux on March 31, 2008.

I stand corrected. It’s much easier to work with the iPod on Ubuntu Linux if you are working with a Windows format instead of Apple format with that little green brick. I’m currently too busy with a project to explain how to fix this little problem so I’m issuing a raincheck. Don’t worry about the if because this is doable. Google around for hfsplus if you feel brave.

From the error messages I’ve encounted it appears that we’ll be reinstalling the filesystem on the iPod and working from there. I may even install ipodlinux if the mood stikes me. In the even you’ve run into these problems and have a suggestion please feel free to pass it along. As long as you’re not spamming I’ll approve the comment.
