As shown in the image, any monitor connected to the HDMI output (direct HDMI to HDMI) will shrink to the center of the screen, and a black border will appear around it.
Do you need to set a file so nobody can delete or edit it? Simple! Set the immutable attribute on the file.
Suppose you have an important info.txt file, a frequently asked questions file, a set of instructions, or even installation scripts that exist on a Samba share. Perhaps these files are accessible via SSH or FTP where write permissions are granted. In any case, they must not be deleted or tampered with, even by root.
“Wow, Ubuntu runs well!”
“Wow, this is lightweight!”
…and a list of other praises come to mind when playing with this ultrabook.
Is there a better netbook or portable computer than the Acer Aspire 722 for running Ubuntu? The Acer Aspire S3 Ultrabookis an attractive, ultra-slim notebook barely larger than a netbook. I wanted to see how well Linux–Ubuntu–would run.
The S3 is a delight to use, and in my experience, it runs Linux better and faster than the bundled Windows 8 despite a few minor issues.
What follows is my enjoyable experience with Ubuntu 12.04 on what is probably one of the best-looking portable computers encountered: The Aspire S3.
The Seagate Momentus XT 750GB hybrid drive attempts to combine SSD speeds with a large 750GB capacity in the space of a laptop hard drive. Does a hybrid drive offer better performance than a regular drive? And, more importantly, how well does it perform in the Acer Aspire One 722 netbook running Ubuntu 10.10 64-bit?
Yes, it is, and it is possible by combining two 64 GB microSDXC cards into a single 128 GB Memory Stick Pro Duo using a dual slot adapter. The result is a single Memory Stick Pro Duo with 128 GB of unformatted capacity.
Since then, Acer has released newer netbooks, such as the Acer Aspire One 756, so, in the never-ending quest to find a better mousetrap, I had to give the 756 a try!
Having acquired a 756 model for myself, it was time to find how it compares to the reliable, time-tested, (mostly) Linux-friendly 722. Have the annoyances been fixed? What is the netbook’s build quality like? Is the 756 faster than the 722? And most importantly, how well does it run Ubuntu 10.10 (my favorite Linux distribution of all time)?
Well, this turned out to be a surprise, leading to several issues I was not expecting. Newer is not always better, and this is a prime example. This review documents my experience and thoughts regarding the Acer Aspire One 756 netbook.
RAID (Redundant Array of Inexpensive Drives) is a hardware technique to improve fault tolerance (the ability to compensate for failures) of data stored on hard drives. There are several variations of RAID, but the common goal is simple: If one hard drive fails, recover data from another.
RAID drives are grouped together into units called arrays. There are two techniques for controlling RAID arrays: Hardware and software. Hardware RAID involves a dedicated hardware RAID controller card, and it is usually faster, more reliable, but more expensive. Software RAID achieves the same result through the operating system and the inexpensive motherboard drive ports, but its performance and reliability are not as good as true hardware RAID.
RAID01 (RAID0+1) and RAID10 (RAID1+0) are two RAID configurations that are easily confused, so here is a brief description to help explain their differences and which is better.
