Free Linux Courses About to Begin! Still Time to Sign up!

THIS IS NOT PROVIDED BY MATTCURRY.COM! It is a 3rd Party Education Company (edX).


The Linux Foundation’s free online course, Introduction to Linux, started today on the edX website. Students have already begun to take the course, which covers the basic tools and techniques commonly used by Linux programmers, system administrators and end users.

It’s not too late to sign up! You can complete the lessons, interact with students and instructors on the message board, and take the tests at your own pace. The first thing you’ll do is install Linux – instructions are available in a PDF sent to all students enrolled in the course. Topics covered during the course include:

– Linux Philosophy and Components

– System Configuration from the Graphical Interface

– Command-line Operations

– Finding Linux Documentation

– File Operations

– Network Operations

– Bash Shell Scripting

-Common Applications

– Local Security Principles

– And more.

The entire course is expected to take about 40 to 60 hours and you may audit the course for free or pay for a certificate of completion.

Put down that Oracle database patch: It could cost $23,000 per CPU

On-by-default INMEMORY tech a boon for developers …

Oracle has released “the most comprehensive patch set” ever for its database software – but its users should be aware of potentially wallet-busting features in the batch.

Version of the database came out on Tuesday and brought with it a range of new features, including Oracle’s hotly anticipated “in memory” tech.

The “in memory” feature, as the name suggests, ensures crucial data – such as frequently accessed records – is kept present in as much RAM as possible, thus accelerating operations. It’s been in development for several years and Oracle had to rewrite “the brain” of its database to make the feature available.

But you don’t just rewrite a brain for free – the in-memory feature costs money, setting you back at least $23,000 per Oracle SPARC processor it’s installed on, we’ve heard.

Where it gets concerning is that in the patch release of the database, the INMEMORY_QUERY switch is enabled by default, according to an analysis of the install by database platform expert Kevin Closson.

Becoming a Non-Profit

Hello all,

I am currently researching all of the steps to become a non-profit in TN, as many of you know I am new to this state.  The laws being different, I want to ensure it is done correctly.  There will likely be fees involved in setting up the non-profit (at least $100, so far).  I am not in a position personally to pay those for the moment.  Anyone who can help donate to get this started would be very well appreciated.  This can be done via the donations page.  As many of you know, I have paid for everything 100% out of my pocket, and I don’t mind doing so.

However, we have recently been given some very bad medical news in the family which has affected our budget considerably.  This is the first time I have ever publicly asked for donations; but even the smallest will help.

Thank you all for your prayers, and consideration.

Painless Move….

I want to start this article out by saying this, in a recent poll of public opinion the I.R.S. was ranked higher than Comcast.  That right there should be a direct indication of how little they care about their customers, and dare us to do anything, being a monopoly that is unregulated makes this possible for them…. That being said, here is my most recent 7 MONTH long experience setting up an account with comcast.

I finally got my internet service restored to what it should be…. This after about 10hrs of calls with Comcast; and them creating 3 false accounts, and failing to activate their own equipment.  Today 7/17/2014, I finally got them to put the speed on my account that they were billing me for (105MB); they had loaded the incorrect configuration in the cable modem.  A Motorola Surfboard SB6411, that I own and is approved on their site.  I was getting an average of 50Mb/s; and I was paying for more than double that.

Also, they were billing me for 2.5x the rate that I was promised.  It was only after 2 BBB complaints, and an additional 3hrs of time on the phone that I was able to get that resolved.  Instead of the $89/mo that I was paying, I finally received the $34.99/mo that I was promised.

In addition to all of this; I moved from Texas to Tennessee in January.  I found out after the move that there is a Data Cap of 300G on ComCast Customers in the Nashville, TN area.  This is absurd; and should not be tolerated.  Why is it ok to do this to people here; and not everywhere else when we are paying the same amount of money.  I moved my account from TX to TN; and I am paying the same amount of money, but now I get phone calls harrassing me about the data limit, and additional charges which are ridiculously high for every gigabyte over 300GB that I use.  I believe that if they are going to do this, that they should be required to notify you before you sign up (which I was not).  They should also have the same rules in every market, this charging more in some markets than others is price gouging at the very least.  We as consumers should rally; and show comcast that we are not to be trifled with.

With the advent of google displaying that some ISPs are so oversubscribed that they can’t even perform well on youtube, now is a good time to get the data we need to prove our point.  Netflix does this as well, as seen below…



Here is googles example of times of day, proving that the network is heavily oversubscribed…

Lab Under Construction

Our new lab is coming together, if anyone has any item they want to use in it please let me know.

Also, if you have equipment you would like hosted in the lab; I am happy to consider it.  The only exceptions would be if the hardware is unsafe; or uses a very large amount of power.  If it is power, we can see if it is justified.

If anyone would like to donate any hardware or Bitcoin, please contact me on the Contacts page; or use the “Donate!” page on the main menu..

Monitor CPU & Hard Drive Temps

Most new computers support ACPI which stands for Advanced Configuration and Power Interface. ACPI provides for many functions besides power management, such as thermal management and plug-and-play events. If the fan on your PC is always on this could mean the CPU and hard drive are running hot and this could cause permanent damage to your PC. There are some command line and GUI based utilities that can be used to monitor the CPU and hard drive temperatures.
Installing the required packages
The following packages need to be installedL

lm-sensors – a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer systems

hddtemp – monitors and reports the temperature of PATA, SATA or SCSI hard drives by reading Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) information on drives that support this feature

sensors-applet(optional – GUI Based) – an applet for the GNOME panel that displays readings from hardware sensors, including temperatures, fan speeds and voltage readings.

computertemp (optional – GUI Based) – little applet for the GNOME desktop that shows the temperature of your CPU and disks in the panel.

psensor (optional GUI Based) – Small applet that gives a good graph over time; and monitors all your sensors along with average cpu usage.
Open terminal window and type the following command
sudo apt-get install lm-sensors hddtemp

Before we can monitor the temperatures we need to configure the sensors. The sensors-detect command helps determine which kernel modules need to be loaded to use lm_sensors most effectively.

Open terminal window and type the following command
sudo sensors-detect

You will be asked a few questions. It is generally safe and recommended to accept the default answers to all questions except the last one – the default is NO. You need to answer yes so that the required entries are made in /etc/modules file.

Next step is to load the new modules into the kernel
sudo service kmod start

Now that you have everything in place you can monitor the CPU and hard drive temperatures either from the command line or add an applet to the GNOME panel.

Command line options
Open terminal window and type the following command(s)
cat /proc/acpi/thermal_zone/*/temperature

Depending on your hardware, you may have more than one sensor.
sudo hddtemp /dev/sda (verify your device paths with ‘fdisk -l’)


That should get you going with monitoring your temperatures; you can use a bash script or application to notify you or even shut the box down if they exceed a certain level.  If there is a request for it I will happily do a write up on both of those tasks.  They are easier that they sound.
