How to run Minecraft on Ubuntu 10.10

Install the openjdk
Copy and paste this into the terminal window (Click Applications –> Accessories –>Terminal)

 sudo apt-get install openjdk-6-jre openjdk-6-jre-headless

Then just download the game to your home folder and run at the terminal

 java -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame


If you have trouble you could try this, it appears as if the filename has changed. This is due to Linux being case sensitive.

 java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame

Backyard wood fired pizza oven DIY – Day 5 – Morning

This morning we lit a small fire on the new slab to allow it to heat slowly as the inside floor slab has only had about 12hours to cure. We should probably have left it for a week or so but the oven is scheduled for use later tonight.

The fire burnt down.

During the inital fire lighting we put a thermometer on the top of the chimney and it reached 200 degrees celcius before we decided to take the thermometer as the temperature reading was still climbing.

 

 

 

In order to take full advantage of the ovens potential it was used to cook breakfast.

Backyard wood fired pizza oven DIY – Day 4

Today we added 75mm of small (25mm) loose rock to the inside of the oven, this layer of rock was then covered with a 40mm concrete slab.

This slab will lock in an air pocket between the base of the oven and the floor level that will act as  insulation between the ground and the inside of the oven.

We have not got any pictures of this process.

Today we stripped the formwork from inside the oven… This took about an hour or so.

Backyard wood fired pizza oven DIY – Day 1

Last weekend we watched a few videos on youtube and then decided that we had the knowledge required to build our own brick pizza oven in the backyard. This process took about 8 hours with 2-3 people working, we still need to render the outside and tile the inside floor but here is the progress so far.

The chosen position.

Measuring out the 1.5m radius from the center peg

3mm ply nailed to the timber pegs for formwork and reinforcement cut

Added plastic waterproof membrane to protect concrete

Pouring 100mm thick concrete base

The template for the arch made from two sheets of 12mm ply with a wrapping of 3mm ply around the sides and top

Concrete slab finished

Starting to brick over arch and around the walls in the still wet concrete

Completed arch

Beginning of the formwork to hold up the brick work while it goes off

The completed formwork to hold the brickwork. This is made of a center post and a few supports from timber wrapped with 3mm ply to form the dome.

Another view of the formwork with the first row of bricks being put in.

Halfway bricked up

Added old clay pipe for chimney

Finished for the day

Sleep for windows 7

I often use my computer as a media player as i go to sleep.

I threw together these two shortcuts to turn my computer off after a hour.

These auto timed shutdown shortucts open the command prompt and schedule a shutdown with the windows shutdown command.

One shortcut starts the shutdown timer and the other one stops the runnning timer incase you change your mind.

These could also be reconfigured to time delay sleep,  hibernate or restart.

Download the two shortcuts here

Lame but mildly successful hacking attempt on my ubuntu 10.4

Ive seen this attack occur on a windows xp machine running realvnc a number of years ago but this time it hit my ubuntu 10.4 machine.

 

I am currently working away from an internet connection so i am using my phone tethered with my computer to get online (see my last post). This configuration gives my laptop my public IP address ( ie no network address translation).

I was sitting at my machine just about to start programming and all of a sudden my mouse starts moving.

I looked at the gnome to panel just as it flashed the “your computer is being remotely controlled” message from the VNC server vino built into ubuntu.

The remote connection then typed the following message as if it was trying to run that command.

You can see the command now in line 8 of my program. Windows users will recognize this as an attempt to open the windows command line.

The remote connection terminated a second later and the attack was over.

I then opened my remote desktop preferences to check whether or not I had turned it on

It doesn’t appear that anyone should have had access as the service was not really activated.

If you look closely you will see however that even though the options are greyed out the box for “allow others users to control…” was ticked and all the security boxes were unticked. I cannot remember what settings i had before the attack and its possible that as part of the attack the settings were changed but as all it tried to do was run a windows command (as far a i could see) i can only assume that the attack was probably not written to attack gnome.

All in all made for a good laugh seeing a windows attack play out on a linux machine. I just hope nothing else happened that i didnt see.

 

Edit: I had a bit of a flip through my system logs and it looks all clean.

Tether your Sony Ericsson Aino or U10i on Linux / Ubuntu

My carrer is Optus in Australia and i’m using Ubuntu 10.4 and i want to be able to connect to the internet via my sony ericsson aino also known as the U10i

Heres the quick how to.

 

Plug in your phone with the usb cableIt will then try to connect to your computer and look for the windows software (this default can be changed)

 

Click cancel on the phone and then choose the linux option

Now on your ubuntu desktop click the network manager icon in the system tray

Now disconnect from the USB wired network this appears to take priority over the 3G connection so the easiest way to get around it is to disconnect from the wired PC-Phone network.

Now Right click the network manager icon

and choose edit connections

Select the Mobile Broadband tab and edit the connection

The phone number shown is generally accepted as common for most carriers but the APN will come from your phone.

On your phone go to Settings–> Connectivity –> Internet Settings

It should look something like this

from here the APN is “internet” as that is what is written under the Connect using heading.

Now click Ok to all the open windows and click on the network manager icon again and now select “Optus” or the name of your carrier and you will be connected
