Installing Java (Ubuntu 10.04)

1. Enable the Cononical Partner Repository in Synaptic (under "other software") and reload.
2. Download sun-java6-jre, sun-java6-plugin and sun-java6-fonts.
3. Set your system to use the Sun Java JRE and Dev packages as the default by typing into a console:

sudo update-java-alternatives --set java-6-sun

Enabling Hardware Sensors in Linux

1. Installing the sensor libraries

First thing’s first – you need to install the libraries that allow Linux to read your sensors. To do this, install the lm-sensors library, by running the command:

sudo apt-get install lm-sensors

This will install the libraries for your motherboard’s sensors. For your hard-disk sensors, you’ll want to install hddtemp:

sudo apt-get install hddtemp

In Ubuntu, the install will ask you several questions. First it will ask if it should run SUID root, select “yes.” It will then ask you for an interval for logging the temperature to a file; since we are going to have an applet display our system temperatures for us, this isn’t necessary, so most users will be fine leaving the default of ‘0′ and pressing enter; if you wish to log this data, however, I’d recommend a value between 2 and 10 seconds. Next, it will ask if it should run as a deamon; select yes, and leave the default values for hostname and port. Finally, it will ask if you wish for it to run on startup – select “yes.”

2. Running sensors-detect

Now that your sensor libraries are installed, you need to detect your sensors! Run the command:

sudo sensors-detect

Which will probe your system for sensors. Answer “YES” to all questions! Don’t just hit enter, type “YES”, because at the end there will be a question for which the default answer is “no”, and we’ll want to answer in the affirmative.
The sensors-detect program will scan yur system, and then give you a summary, stating which sensors it has found. It will then say: I will now generate the commands needed to load the required modules. After you hit ENTER to continue, it will ask, Do you want to add these lines to /etc/modules automatically? (yes/NO) This is the question we want to make sure we answer YES to.

3. Loading the modules

Since we answered YES to the previous question, our sensor modules will be loaded by default the next time we start up. But since we don’t want to have to reboot, we’re going to use the information we got from the sensors-detect script to load the modules ourselves, this time only. Right above the last question will appear a list of modules that you should load, in the form of:

#----cut here----
# Chip drivers
smsc47m1
#----cut here----

You may have more, or different, items listed – that’s fine! What we want to do now, to load these modules, is use the modprobe command, as follows:

sudo modprobe [module name]

So, in my case, I would type:

sudo modprobe smsc47m1

If all goes well, you should be returned to the command-line, without any output.

4. Monitoring the sensors!

Wow, that was a lot of work! Now, let’s see the rewards. On the command line, you can simply run the

sensors

command; this will output the information from your motherboard’s sensors.
However, we’d rather have a graphical interface for checking up on our hardware, so let’s install an applet for our Gnome desktop to keep an eye on our system’s temperature. Run the command:

sudo apt-get install sensors-applet

to install the applet. Now, add the applet by right-clicking on your desktop panel, selecting “Add to Panel,” and you will now see a “Hardware Sensors Monitor” applet in the System & Hardware section. Click and drag this to your panel to add it.
The applet will now say that you haven’t enabled any sensors; right click on the applet and open its preferences. The first screen is for general settings:

The options here are self-explanatory; for update interval, choose a value between two and ten seconds. The second screen is where you can enable your sensors to be displayed in the applet:

Here we have my hard drive, /dev/sda, enabled. Simply check off the sensors you want to enable, and they will appear in your panel!

Conclusion

Hopefully by now, you’ll see icons in your panel, with thermometers and temperature readouts, keeping you apprised of the status of your system’s hardware. You’ll notice that when doing intensive operations, various parts of your system will increase in temperature; this is normal, and this applet will help you keep an eye on things so nothing overheats.

Fixing Java in Opera

If you start Opera from the console you may see the following error message if java doesn't work correctly:

ERROR: ld.so: object 'libjvm.so' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object 'libawt.so' from LD_PRELOAD cannot be preloaded: ignored.

To fix this, correct the Java path under Tools -> Preferences -> Advanced Tab -> Content -> Java options. It should look similar to this:

/usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/lib/i386/

Check your installed Java pathways and change accordingly.

Installing ISA 2.X Using Wine (Ubuntu)

1. Download and install ISA program file and bible modules using Wine. DO NOT START APPLICATION AT THE END OF INSTALLING!

2. Add Symbol.ttf to .wine/drive_C/windows/Fonts.

3. Copy usp10.dll to .wine/drive_C/windows/system32. (Often not necessary as it already exists).

4. Add ISA.exe to wine-config "applications".

5. Under "Libraries" add riched20.dll, riched 32.dll and usp10.dll.

Installing eSword 9.X Using Wine (Ubuntu)

1. Install wine 906 using wine, but do NOT start.

2. Copy mfc42.dll and msls31.dll to .wine/drive_c/windows/system32.

3. Add oleaut32.dll and riched20.dll to "libraries" (sometimes you may need to change the load order of both to "Native: Windows").

4. Start eSword.

File Deletion using "Shred"

shred: Delete a file securely, first overwriting it to hide its contents.

It is available on most of Linux distributions including Debian GNU/Linux. To remove file called personalinfo.tar.gz :

$ shred -n 200 -z -u personalinfo.tar.gz

Where,

* -n: Overwrite N (200) times instead of the default (25)
* -z: Add a final overwrite with zeros to hide shreddin
* -u: Truncate and remove file after overwriting

Read the man page of shred(1) for more information. Most of these utilities are not effective (read as useless) only if :

* File system is log-structured or journaled filesystems, such as JFS, ReiserFS, XFS, Ext3 etc
* Your filesystems is RAID-based, compressed filesystem etc
* In addition, file system backups and remote mirrors may contain copies of the file that cannot be removed by these utilities.

Crash - Backup!

Step 1 - TcpAckFrequency

NOTE if you are running Windows Vista this setting may not have any effect - a hotfix is needed which i'm tracking down. This works fine under Windows XP

Type "regedit" in windows "run.." dialog to bring up registry menu

Then find:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic
es\Tcpip\Parameters\Interfaces\

There will be multiple NIC interfaces listed in there, find the one you use to connect to the internet, there will be several interfaces listed (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have lots of settings in it and you will see your machines IP address listed there somewhere. Right-click in the right hand pane and add a new DWORD value, name it TcpAckFrequency, then right click the entry and click Modify and assign a value of 1.

You can change it back to 2 (default) at a later stage if it affects your other TCP application performance. it tells windows how many TCP packets to wait before sending ACK. if the value is 1, windows will send ACK every time it receives a TCP package.

Step 2 - TCPNoDelay

Type "regedit" in windows "run.." dialog to bring up registry menu

Then find:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Paramet
ers

Right-click in the right hand pane and add a new DWORD value, name it TCPNoDelay, then right click the entry and click Modify and assign a value of 1.

Click Ok and close the registry editor, then reboot your PC.

Flash Player Glitches

Removing Conflicting Plugins

Ubuntu comes with swfdec plug-in, but it doesn't work on several sites. Installing the version from Adobe might solve this problem and improve performance.

To remove other flash plug-ins and install only the one from Adobe open "Applications >> Accessories >> Terminal", then paste (CTRL+SHIFT+V) the code below in the terminal window and hit enter:

sudo apt-get remove swfdec-mozilla
sudo apt-get remove mozilla-plugin-gnash
sudo apt-get remove adobe-flashplugin
sudo apt-get remove flashplugin-nonfree
sudo apt-get install flashplugin-nonfree

Flash Tweaks

If you're still encountering problems, try:

sudo mkdir /etc/adobe
echo "OverrideGPUValidation=true" >~/mms.cfg
sudo mv ~/mms.cfg /etc/adobe/
