Linux is the UNIX like operating system that uses the Linux kernel of Monolithic type. The OS is being installed on a vast range of tablet computers, mobiles, video game consoles, mainframes, super computers etc. Even, statistics says that as, server OS, LINUX accounts more than 50% of the whole global installations. Also,over the years, Linux operating system has gained fair amount of popularity among the common home users with the Fedora, Ubuntu and OpenSUSE distributions. Moreover, with the egression of smart phones, netbooks etc, which are running on embedded LINUX, the operating system has been more closely used by many users. Though Linux has advanced technology and features, sometimes, some errors lead to data loss or inaccessibility and you need to look for any Linux data recovery software to recover back your valuable data.

In day to day usage of a Linux system, there can be enormous possibility of data loss situations, and you may not always successful in trouble shooting the system to gain access of your data. Hence, if you don’t have a valid backup available or failed to restore the data from the backup, Linux recovery is the answer to bring back your data.

Common data loss situations in Linux:

Error Mount wrong fs type, bad option, bad super block on /dev/hdb2.
Error Too many mounted file systems.
File system error.
Grub Error 12 Invalid device requested.
Grub Error 17 Can not mount selected partition.

There can be many such errors leading to the loss or inaccessibility of your Linux data. In such cases, if you are a technical person, then you can trouble shoot at the low-level. You can run the ‘fsck’ command to detect and fix such error. Prior to running the ‘fsck’ command, first, you need to go to the single user mode. Then, you have to unmount the file system partition, you are going to work upon, if it is not the root file system. If you don’t take enough care to unmount the file system, the ‘fsck warns you, such as- ‘The file system is mounted, do you want to continue anyway?’ Saying yes to the message, may result in the loss of your data, because, at times, ‘fsck’ writes directly to the disk.

If you need to check the root file system based partition, you have to boot the system in single user mode and run the ‘fsck’ with a ‘-b’ option so that it will run in a read-only mode. Also, the ‘-b’ option directly go to the ‘init’ and makes an emergency booting while skipping the other start-up scripts.

Sometimes, ‘fsck’ fails to run or exits without running at all. At that time, you need to force run the utility with ‘-f’ option. This is a case of severe corruption and you need to give additional information to ‘fsck’, such as the size of the alternate superblock or the address of the superblock to fetch the data and fix the error.

However, sometimes, these low-level recovery process is tedious as well as risky with respect to your valuable data. Hence, you can go for any Linux data recovery software, which can recover the data for you safely.

Maintaining Your Mac

Mac and the OS X are very stable and reliable. However, if you want your Mac to work perfectly you have to maintain it properly. Most of the errors and glitches that happen to your mac are caused by incorrect permissions table. Mac OS X as a UNIX based system has a UNIX way of handling the files. UNIX as a multi-user system has a special way of manipulating file access. (More about file permissions you can read here). When the new software is installed on your Mac or you did some other system tweaks, it’s very likely that permissions will mess itself up so you wont be able executing applications or it may happen that your mac is acting weird. The easiest way of fixing permissions is by using Mac OS X “Disk Utility” which can be found in /Applications/Utilities folder.

Fixing permissions is recommended before and after installing any software to your mac as well as installing any software updates. There are various software available on the Internet to help you keep your Mac maintained and in a “good health”. Software such as Onyx or Cocktail are doing a great job by not only repairing and verifying permissions for you but also cleaning the internet history,cache,temporary files and running optimization scripts.

If you for some reason are unable to boot your system,before you do anything like re-installing the OS, try pressing command + S on the system boot-up and it will get you into console mode. Type in /sbin/fsck -fy and hit enter. Do that couple of times until it doesn’t say “System Modified”. Before you use “fsck” command, I advise you to open terminal, type in man fsck and read the manual page carefully. Not all software errors are as easy to fix by using methods above. Some errors and system misbehaving can indicate serious hardware failure so if the problems persist, the best is to take your mac to an authorized Apple service for a check-up.

Alternative For SWF On Your Site

Today many resource masters use SWF files on their sites. They are trying to make web pages more catching and hence more popular. At first sight, it’s OK. SWF elements make web page eye-catching and catchy. But on the other hand there is the problem that may affect the traffic of resource, and therefore the profit.
Why this is possible? In fact not all people have Macromedia Flash player installed on their system, so they may cannot see your flash animation at all. And therefore they cannot see such important sides of resource as banners, animated buttons, menus etc. So you can lose potential clients.

So what should I do? – you may ask. I was thinking about this issue for a long time, and finally I’ve found a great solution. We all know about an animated GIF format, that is de-facto standard in Internet world. This format is supported by totally all browsers, and people don’t have to use additional software to be able to see GIFs. So why to do not try to convert our Flash to GIF animation? To do this, we will need a utility for Flash to GIF converting.

I have spent a lot of time while seeking for a lot of tools in this category. And finally I’ve found stunning application SWF-AVI-GIF Converter, that has a power to solve our problem. It is made for easy and quick Flash to GIF conversion.

When I have used it first time, I was very impressed by the interface. It is cool and easy-to-use. Actually this program is not only for SWF to GIF transcoding. It is also able to transcode SWF to GIF, FLV to AVI, video to animated GIF and SWF to JPEG series. But we only need the 1st option – Flash to GIF. So at first, we open our flash file (both SWF and FLV files are allowed). Second, we have to edit the GIF: there are many controls on this tab. So we can edit the Frame rate. This is how frequently slides move in the animated GIF. The higher this value is, the smooter will be output GIF. The next control is a color depth. The value is 8 bits by default, but if you need something else, you can pick up “As in source” value. The next important option is size of the final GIF – width and height. Just edit these values and you will see how the resulting image will look like on Preview area. The final three parameters are not so important, but who knows?.. Thus you are allowed to enter the “Loop GIF animation” setting, so that the final GIF will be animated forever. If you turn off that option – the GIF will be played just once. You can also choose the Transparent color and Background color. When all changes are ready, we are ready to initiate the conversion. Just click the “Start GIF recording” button, and that’s it. The software will complete the encoding work, and you can save your GIF to any directory on the PC.

When you received your animated GIF, you can move it to the server and rewrite previous SWF animation on your web page. This is it. You will not have questions with SWF compatibilities anymore.

Download and use for free this powerful SWF to GIF encoder tool. I am sure you will be amazed, and your problems will be solved.

New Trends In Teaching Children To Read

If we are interested in our children doing better in school, then it’s important to understand the reasons why they are not. During the last couple of decades new views of reading instruction emerged and morphed in school districts nationwide.

The question became – are phonics versus whole language methods better for beginning readers? As it turns out, educators are now struggling to blend these reading programs and tailor them for each child.

Known as “the reading wars,” initially waged during the 1980s and ’90s, it was around 1987 when personal journals became one of the latest classroom tactics for teaching kids to read. Known as whole language, it was an instructional philosophy emphasizing that children focus on meaning, which contrasts with phonics based methods of teaching reading and writing.

Then, many people believed that children were poor readers because the old school approach emphasizing phonics. The fact that memorization ended up turning reading into a chore alienated many of the kids from reading, period. The National Reading Panel reported findings about Phonics for Reading as a research-based program that: delivers direct instruction in phonics increases fluency with Second and Third levels provides word-recognition and spelling instruction, plus story reading, and independent activities.

It is also important to realize that the parents are a child’s first teachers. Toddlers learn a lot at home so it is critical to talk alot. Children will learn about spoken words just from listening to their parents. Parents take note: read to your child; share books you loved and try some new ones from the library and then reread favorites over and over again.

Whole language learning proved to be a disaster. Eight years after this method first appeared in California grade schools, by the mid-90s, the fourth-grader’s reading scores had plummeted to the bottom of the national list. Source: The National Assessment of Educational Progress(NAEP).

By 1997, Congress formed the National Reading Panel to evaluate the research on teaching practices wiht the intent on determining what worked. Then there was a federal program called the No Child Left Behind Act requiring school districts to use scientifically proven methods. The goal? This will hopefully make children proficient in math and reading by the year 2014. Six years after No Child Left Behind’s passage, a lot of data has been collected about the academic performance of both students and schools.

Today there is a trend towards balanced or comprehensive literacy, and most educators agree that there’s no one single program that fits all children for developing reading skills.
