The MacBook Air SSDs From Samsung are Faster

According to Ars Technica, Apple is now shipping MacBook Airs with SSDs that are made by Samsung instead of the original SSDs supplied by Toshiba. The switch seems to increase writing and reading performance speeds, on the 2010 MacBook Airs by 20-25 percent, according to tests performed by AnandTech.

I happen to have the MacBook Air, purchased around early December 2010. I wanted to know if I have the original Toshiba SSD or the new Samsung SSD. Before I digging in, I had a feeling that I had the older SSD. I have been very happy with my MacBook Air since I purchased it. But, knowing if I had the faster SSD would be nice.

Go to the System Profiler by accessing the Apple menu and then clicking About this Mac. Go to the section called Serial-ATA, you will see the Model number of your SSD device. Mine says: APPLE SSD TS128C. That means I have the older Toshiba.

It would have been nice to have the faster Samsung SSD, but I have been very happy with my new MacBook Air’s performance. No complaints here. So the question is, how do I get the new SSDs? Is it even possible to swap devices?

Comcast Now At 105Mbps

Comcast is rolling out the fastest Internet connection in the country. It’s called Extreme 105. Comcast plans to roll Extreme 105 to more than 40 million cable users across the United States. The new service is clocked at 105Mbps, almost double the speed of its current offering.

The fast internet connection comes with a price, at you guess it, $105 per month. And that’s with triple play, meaning you need to have TV and telephone package also as part of the entire deal. If you want the Extreme 105 only, you will need to fork out $199 per month.

And one more thing, Comcast still enforces its 250 GB cap limit. So, with all that speed, you may have to curb down your downloads towards the end of the month. It’s akin to driving a Lamborghini in the fast lane for 40 miles and then driving down in the slow lane for the next 20.

Technology and Food Ads

So much for content ads. It was long understood that Google Ads were based on content. So, if your blog or website is about technology, you will most likely get served with ads about technology, but it’s not always the case.

Lately, one of my ads have been about food. What does food have anything to do with technology? Well, I guess there are exceptions. I never really figured out why certain ads will show up that are completely unrelated to my content.

I know all geeks needs to eat, but shouldn’t the ads be about technology, like hosting, iPad 2, the cloud, etc. So, why Groupon Foods or pizza? Anyways, it’s making me hungry.

Just some interesting observations. That is all.

CentOS 5.6 Downloaded

I saw a couple of great articles lauding about the latest CentOS 5.6 distribution. It mentions that CentOS is a good alternative to Red Hat for smaller companies who may not need the support. It’s also free.

CentOS is of course based on Red Hat and is a favorite OS of many hosting companies. Hostgator runs on CentOS. So, this blog is actually powered by CentOS. Who would have thunk it?

So, I decided to download the latest CentOS 5.6 distro overnight. I’m now in the process of installing CentOS in VirtualBox on my desktop. I will write a follow up article reviewing CentOS 5.6.

Ubuntu 8.04 Hardy Heron Ending on May 12

Ubuntu will stop supporting Ubuntu 8.04 aka Hardy Heron on May 12th. That means no software updates and no security fixes for this old favorite. Hardy Heron was one of my favorite Ubuntu releases ever. I was with Hardy Heron for more than a year, mainly because it was very stable and had long term support. I continued to use Hardy even when 8.10 and 9.04 were out. I’m using Ubuntu 10.04 LTS now. Like they say, all good things come to an end. We will miss you, Hardy. Ok, now to Ubuntu 11.04. What’s up with this Unity interface?

IE9 Will Not Run on Windows XP

Microsoft has been pushing hard to get Windows users to adopt IE9. Interestingly enough, the target seems to be just half the audience. It’s similar to shooting at one half of the target. The main reason for this is that IE 9, will not work on Windows XP.

Considering that 54% of Windows users are still running Windows XP, it looks like Microsoft is quite limited as to where it can push IE9. Or could it be Microsoft’s way of forcing users to upgrade to Windows 7. But, it’s highly unlikely, because Windows XP users can easily download and run the Chrome and Firefox.

The interesting question is, will IE9 change the browser market share? Probably not. I see more and more people switching to tablets and smart phones to access the web. It’s an area where IE has very little presence. So, expect Firefox and Chrome use to continue to rise. It will be interesting to see how the browser market share will look like in a few years.

Apache Error: Fully Qualified Domain Name

I recently installed Ubuntu and the Apache web server on another desktop computer. If you like to know how to install Apache, please read my previous post about installing LAMP. In this instance, installing Ubuntu and Apache was a success. There is one minor issue however. Every time I restart the Apache web server, I would get this annoying message: “Could not reliably determine the server’s fully qualified domain name.” The error is more of a warning. It does not really affect the way Apache display web pages. It’s more of annoyance more than anything.

So, how do you get rid of this minor Apache error?

First things first, one of the things I would like to do when I install a new instance of Ubuntu is to assign the desktop’s hostname to “localhost.” In this case, I don’t have to worry about the hostname resolving to itself, since localhost is already bound to 127.0.0.1. You can change your hostname to localhost by typing this command on the Terminal:

sudo hostname localhost

You don’t have to do this if you prefer another hostname.

Now, to fixing the minor nuisance.

Edit the Apache config: /etc/apache2/apache2.conf.

You will need to edit the Apache configuration and add your hostname as ServerName. You can edit the file via the Terminal and using either vi or Gedit. I prefer to work vi for minor changes. Gedit is probably easier for most.

sudo vi /etc/apache2/apache2.conf

or

sudo gedit /etc/apache2/apache2.conf

If you haven’t done anything previously to the Apache configuration, it will probably be an empty file. In my case, it was. Just add the following:

ServerName localhost

If you are going to use a different hostname, you will need to add the fully qualified domain name or FQDN in this format.

ServerName hostname.domain.com

After saving your changes, you will need to restart Apache to see if that minor annoyance is gone.

To restart Apache, type:

sudo /etc/init.d/apache2 restart

Change Default Terminal Size in Ubuntu

Every time I open a new Terminal in Ubuntu, the first order of business for me is to increase the screen size to 132×24. The default Ubuntu setting is 80×24. It’s just too narrow for me. I would like to be able to see the entire command in a single line without it wrapping down to the next line. I always end up increasing the Terminal size to 132×24 almost every time.

There has to be a way to make 132×24 the default size. So, here it is. To make 132×24 the default size for Terminal, you need to perform the following.

You need to edit the termcap file found at:

sudo gedit /usr/share/vte/termcap/xterm

Look for this entry:

:co#80:it#8:li#24:\

and replace it with:

:co#132:it#8:li#24:\

Save. Changes will not take effect until you start a new Terminal session.

Simple Invoices Quotation

I have professed my love for Simple Invoices previously on this blog. Simple Invoices is a free, open-source, web-based invoicing system that can be installed on your desktop or web server. In fact, I use Simple Invoices on one of my businesses.

Today, I started using the Quotation feature. Quotations are not much different than Invoices. The only difference that you save the form as a Quote instead of Invoice. The default selection is Invoice.

A quote can be easily converted later to an invoice later by simply changing the category. Simple enough. If you need an web-based invoicing system, be sure to check Simple Invoices.
