There are two extreme schools of thought on ergonomics. One says if you are sitting comfortably you probably don’t have a problem. The other says nonsense, you’ll be doing all sorts of damage – and what you need is a custom-built ergonomic chair…. here’s one for only £600 just in from America. The good news is that the way in which the £600-a-shot brigade has it right is that it needn’t cost a lot of money every time. “Many people do spend a lot of money on chairs that are labeled ergonomic, but the actual guidelines on what makes an ergonomic chair is just that you can adjust it in terms of more than height,” Says Paul Godfrey, director of ergonomics specialist Health and Fitness Solutions. “You get one or two companies spending a lot thinking the more they spend the better the chair will be, but it’s all about adjustability.”

Essentially, what’s ergonomic for one person isn’t necessarily going to be ergonomic for someone else.

“You’re not going to be able to find one chair to fit all. When you take all the heights and sizes and body frames you’ll find in a company and try to fit it into one chair, you realise that even if various components of the chairs adjust, it still won’t fit the individual,” says Godfrey.

It’s worth considering what is meant by “ergonomic” in terms of chairs. The hollow of the back should be supported and the feet should rest comfortably on the ground or else a footrest. The elbows should be about level with the keyboard for comfortable typing and the top of the monitor should be at eye level. And that’s about it for beginners. It should be apparent from those components that the chair is only one element of the deal.

“A lot of people pay attention to the chair and forget that you need a good marriage between the chair and the desk,” says Godfrey. “Most desks are made to 700-720mm high. Unless you are 5ft 4in or shorter, 720mm is going to be too low for most people.” So you have a new ergonomic chair at the right height but sit too high and lean forward or compromise your sitting position by dropping the chair height.

The results can be complaining employees, which gets difficult because the people making the decisions about spending feel they’ve “done” ergonomics and it didn’t work. “When directors spend money on furniture and they don’t get the return on their investment that they’d hoped for, their perceptions of ergonomics have become negative,” says ergonomist Herman Bynke. “They are removed from the subject matter and they really don’t believe in ergonomics afterwards.” Bynke believes it isn’t enough to spend a lot on the state-of-the-art chairs. “Ergonomics is all about the fit between the human being and the equipment. It’s a big picture, and the ergonomics in the office environment is still focussed on the chair.

Godfrey agrees that people need to look further than the furniture. “People expect that good ergonomics are going to take their aches and pains away,” he says. “They need to understand that even when you’re sitting properly at a chair that’s been designed for you, with the right desk height and so on, you’re still sitting. We’re hunter gatherers, and the whole office environment has evolved over the last 20 years, while we haven’t evolved for many thousands. We like to be upright, we like to move about and the fact that you’re sitting well doesn’t take away the fact that you’re sitting.” People need to understand that they should get up for ten minutes an hour, and that staring at a screen for ages isn’t going to be a good idea, he says.

There is a lot that can be done without spending a lot of money. People make the mistake, says Bynke, of putting their screens to the side of the desk rather than looking straight at them – crick in the neck anyone? They put the documents on which they are working on the desk rather than at the same height as the monitor. Notebook users often seem to think that the monitor height rule doesn’t apply to them: stands for notebook computers are available though, for example the Notebook Station USB from Kensington.

“People forget that these products are designed for working on the move, not for sustained use, and therefore they sit hunched over their laptop for far too long,” says Phil O’Neill, director and business manager for Kensington Europe.

Lighting is also important. The Verilux Happy Eyes range is among those that imitates daylight, which is whiter than the yellowish artificial light to which most people have become accustomed. Overall, the way people make mistakes appears mostly to involve overlooking the basics. If you’re sitting badly, chances are you know you’re doing it, and if your staff are doing it so you’ll be able to spot it.

If you’re embarking on investigating the ergonomics of your environment for the first time, consider asking your staff whether they’re comfortable and educating them about the correct use of their equipment before spending a fortune – a high spend might prove unnecessary.

Which filesystems have the largest metadata overhead[1]? We can find out using guestfish sparse file support and a short shell script:

#!/bin/sh -

guestfish=fish/guestfish
testimg=/mnt/tmp/test/test.img
size=1G

for fstype in ext2 ext3 ext4 xfs ntfs msdos ; do
    $guestfish <<EOF
      sparse $testimg $size
      run
      sfdiskM /dev/sda ,
      mkfs $fstype /dev/sda1
EOF
    echo -n "$fstype: "
    du $testimg
done

The results:

Notes

[1] Yes, there are shortcomings in the methodology. What this really measures is how many blocks are written by the mkfs program. Even if you believe the figures, this only measures the initial overhead, but you can use the same technique to measure the overhead of storing (eg) lots of small files, or whatever is appropriate for your workload.
[2] Note the difference between ext2 and ext3/4 seems to be entirely down to the size of the journal, which is a kind of metadata overhead, but one that you can easily control.
[3] Needs three small patches to libguestfs to get these filesystems to work.
[4] This seems off the scale — needs further investigation.

Difficulty: Beginner

Requirements:

• Notepad
• Text Document

Ok so what is ADS?

ADS stands for (Alternative Data Streams) and is pretty much native to the NTFS partitions which is basically native to Windows. They created ADS back when they came out with windows NT which was in 2000. They basically made it so their systems could be compatible with the Macistosh HFS systems which was the file systems they used . ADS was typically used back in 2000 to store things such as author or title file attributes and stuff like image thumbnails.

However, when windows XP came out they added the Attachment Execution Service that stores details on the origin of downloaded files in alternate data streams attached to files, in an effort to protect users from downloaded files that may present a risk

In simpliar terms what ADS basically does is it forks the file information into seperate resources. If you guys wanna know more about the hfs and ADS go look it up! Google is your friend.

Alright so lets get started.

1. First you want to make a folder

So open up command prompt and you can do this by going to Start>All Programs> and then Accessories and then selecting Command Prompt in the menu. Also if you have Windows Vista you might wanna run this as administrator.

Next navigate to your C:\ drive by typing cd\

Figure 1.1:

Now we want to create a folder. To do this type mkdir which is the command to make a folder and then type the name of the folder and press enter. In this tutorial I’m gonna name my folder ADS For example:

Figure 1.2:

To make sure this worked correctly type dir and press enter. It should have the ADS folder listed in the directory.

Figure 1.3:

2. Gather the requirements

Alright so now that you have a folder created were gonna need some objects or files I should say to make this work.

So first navigate to your previously created folder in our case ADS by typing cd  (folder name) and pressing enter. For example look at figure 1.4

Figure 1.4:

ok now go to Start>Accessories and then right click Notepad.exe and select open file location. For example look at the figure 1.5.

Figure 1.5:

Next copy notepad.exe and paste it inside the folder you created earlier. For example look at Figure 1.6 and 1.7

Figure 1.6:

Figure 1.7:

After your done it should look like figure 1.8.

Figure 1.8:

Next we’ll need to create a txt document and you can do this one or two ways. One way is in cmd to type notepad example.txt and then selecting YES when the dialog box asks you if you want to make this a file or by going to My Computer and opening your C:\ Drive and then navigating to the folder you created and right clicking inside the folder and selecting new text document and then renaming it to whatever you want it to be named. For example look at Figures 1.9 and 1.10.

Figure 1.9:

Figure 1.10:

So now I can type a dir command in cmd to show the contents of this folder and you will now notice that we have text document named example.txt. For example look at Figure 1.11.

Figure 1.11:

Alright so now that we have our txt document lets just type a little something in there

we’ll type HELLO WORLD!

Then go to file and select save

Figure 1.12:

Ok now that we have everything we can go to cmd and type notepad example.txt again and press enter and we should get our Hello World!

Figure 1.13:

3. Executing the ADS command

Alright so this next command your gonna wanna pay close attention to cause this is the command that makes this whole thing work.

In cmd type the following:

• echo test > c:\ads\example.txt:hidden.txt and press enter.

Figure 1.14:

Notice the command specifies the word test in the txt document. This is what is displayed in the hidden.txt document

Now type dir in cmd again and you’ll notice there is no hidden.txt file listed in the directory as displayed in Figure 1.15

Figure 1.15:

But if i type notepad c:\ads\example.txt:hidden.txt you will see that we have our hidden document and it says test as we specified before.For example look at Figure 1.16

Figure 1.16:

Alright so this was just a basic usage of ADS , but you can lots more such hiding txt documents inside mp3’s .exe files, etc

Headaches are something that affects most adults through their lives and are one of the most common reasons for visiting a GP.

At first they may be quite worrying, but in fact only a very small percentage are actually caused by anything sinister. A doctor or neurologist will usually satisfy themselves quite quickly that there is nothing seriously wrong simply through routine examination. Quite often patients seem to need more than simple reassurance from a specialist and want to have a scan done before their minds are set at ease. The danger of this is that scans can show other things that whilst perhaps not anything to worry about actually have the opposite effect on the patient.

There are many different types of headaches that have been classified in the medical world but the exact mechanisms that cause most common headache types are still being researched and debated.

It is becoming increasingly obvious, however, that with lots of simple headaches there are also underlying disorders with the neck as well as head pain. These are often ignored because they are not of primary concern to the headache sufferer and often the symptoms in the neck are very minor and only perceived perhaps as stiffness. This association between the neck and the head is often overlooked by patients and clinicians alike.

Physiotherapists who treat headaches regularly are expert in identifying joint disorders and related soft tissue and muscle problems in the upper part of the neck. Regardless of where it is in a “chicken and egg” debate this relationship exists and physiotherapy has proven success in treating many headaches even when they have already been diagnosed as migraine or cluster headache for example.

We have many case studies where our patients have had daily headaches for many years that have been treated completely within weeks just by improving the condition the tissues in the neck and ensuring that the patient improves spinal posture and work habits.

Vecchio argomento ma sempre di moda, quindi suggerisco un paio di tool free per questo scopo:

NTFS su OS X
NTFS viene letto da Mac nativamente, ma per scriverci serve NTFS-3G che installa un driver che effettua il mount dei volumi NTFS in read+write: http://macntfs-3g.blogspot.com/
Utilizza MacFUSE , quindi è necessario prima installare questo componente: http://code.google.com/p/macfuse/.

Nota: Mentre NTFS-3G è compatibile con il kernel a 64bit di Snow Leopard, MacFuse ancora no (ad oggi), quindi è necessario attendere un update di quel componente prima di poterlo usare con il kernel a 64bit di 10.6.

HFS+ su WIN
HFSExplorer è free e permette di aprire i volumi formattati con il filesystem di OS X. L’ho usato pochissimo visto che non sono un utente Bootcamp, però funzionava a dovere: http://hem.bredband.net/catacombae/hfsx.html

Nota: non permette di scrivere su HFS+, per tale funzione potete comprare questo prodotto: MacDrive (a partire da circa 50$)

If you’re not familiar with Mac OS X, it uses a packaging format derived from NextStep where applications are directories and to install an application, you just drag and drop the package directory into the “Applications” folder (or wherever you choose because apps are self-contained and can run from anywhere).

Mac OS X installers use a file format called an “Apple disk image” or *.dmg file, which is a sort of bzip2-compressed filesystem. In the example below, I downloaded the binary installer for the brilliant open source video player VLC, and double-clicked on it, whereupon Mac OS X mounts the packaged filesystem. In the image below, the VLC application looks like a file but in reality is a directory full of application files.

Can we decode and unpack these .dmg files in Linux using libguestfs? Well, not always, but sometimes (because of some limitations in the Linux HFS+ driver described below).

First I should note that this probably doesn’t work with password-protected / encrypted files, but they’re not common for software distribution. DMGExtractor claims it can handle those.

Secondly the image is usually bzip2-compressed, and you have to run bunzip2 on it by hand first:

$ mv Firefox\ 3.5.3.dmg firefox-3.5.3.dmg.bz2
$ bunzip2 firefox-3.5.3.dmg.bz2
bunzip2: firefox-3.5.3.dmg.bz2: trailing garbage after EOF ignored

(Yeah, I don’t know how important that error was either … But it doesn’t seem to affect things.)

Thirdly the file system image is not at the start of the file. You have to find it and strip off some sort of header from the file. Look for the HFS+ superblock in the file:

$ hexdump -C firefox-3.5.3.dmg | grep '  48 2b 00 04'
00008400  48 2b 00 04 00 00 01 00  63 65 72 64 00 00 00 00  |H+......cerd....|
^C

and strip it, less 0×400 bytes:

$ dd if=firefox-3.5.3.dmg of=firefox.img bs=$((0x8400 - 0x400)) skip=1

This should produce an HFS+ filesystem image. Check that:

$ file firefox.img
firefox.img: Macintosh HFS Extended version 4 data last mounted by: 'cerd',
created: Mon Aug 24 10:37:21 2009, last modified: Mon Aug 24 18:37:21 2009,
last backup: Mon Aug 24 18:37:21 2009, last checked: Mon Aug 24 18:37:21 2009,
block size: 2048, number of blocks: 25773, free blocks: 0

Now this can be loaded directly into guestfish:

$ guestfish --ro -a firefox.img -m /dev/sda

Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.

Type: 'help' for help with commands
      'quit' to quit the shell

><fs> ll /
total 180
lrwxrwxr-x  1  502   80     13 Aug 24 13:37   -> /Applications
drwxr-xr-x  1  502   80      7 Aug 24 13:37 .
dr-xr-xr-x 29 root root      0 Oct 25 17:41 ..
-rwxr-xr-x  1  502   80  12292 Aug 24 12:41 .DS_Store

drwxr-xr-x  1  502   80      3 Aug 24 13:33 Firefox.app

and in this case, I just wanted to extract the contents to a tarball, so:

><fs> tgz-out / firefox.tgz

$ zcat firefox.tgz | tar tf -
./
./
./.background/
./.background/background.png
./.DS_Store
./.VolumeIcon.icns
./Firefox.app/
./Firefox.app/Contents/
./Firefox.app/Contents/Info.plist
./Firefox.app/Contents/MacOS/
./Firefox.app/Contents/MacOS/.autoreg
./Firefox.app/Contents/MacOS/application.ini
./Firefox.app/Contents/MacOS/blocklist.xml
./Firefox.app/Contents/MacOS/browserconfig.properties
./Firefox.app/Contents/MacOS/chrome/
[etc]

“hfs: failed to load catalog file”

It worked with the Firefox installer, but two other installers I tried (for VLC and Disk Inventory X) didn’t go so well. The HFS+ driver produced this error for those:

hfs: failed to load catalog file

which as far as I can see is either a problem that these .dmg files don’t follow the HFS+ [proprietary] standard by missing out the catalog B-tree, or else the HFS+ driver can’t find that B-tree for unknown reasons.

Kindergarten – We continue to work on mouse control while learning about the Internet, alphabet and letter sounds. We are going into the website starfall.com

First grade – We have been working on typing sentences with uppercase letters and proper spacing. We will be making pictographs next.

Second grade – We are learning about copying and pasting by making pictures in Kid Pix. We are also learning how to go back and forth between documents.

Third grade – We have finished our Scranimals. We will be doing some Internet safety things next along with working on long vowel sounds.

Fourth grade – We are working on a state project. Lots of skills in this project: Internet research, using a table to keep track of our notes, creating a brochure.

Fifth grade – We are making maps of an imaginary country. We are using various applications, word processing, Kid Pix for drawing and the Internet. Lots of going between applications and saving correctly.

Sixth grade – We are learning about spreadsheets and some of the simple things that can be done. Resizing of cells, entering information and changing that. Later in the year we will get into using a spreadsheet to do calculations.

We have been working hard learning how to control the mouse. In Kid Pix we are learning some of the many tools that we can use to draw. We have used the pencil tool, paint bursh and paint can. We are making elephants for the Elemer’s Day parade. At conferences, see if you can find Elmer.

The third graders are working on a project based on the book “Scranimals” by Jack Prelutsky. They need to pick an animal and then a food or plant that starts with the last 2 or last letter of the animal. Here are some examples: Roselephant, Avocadodos, Parrotter, Potatoad. I suggested that they use the Internet to find a large select of animal, plant, and food lists. Do a google search by tpying in list of animals, list of foods, list of plants. Let’s see how creative we can get.

If you have played around with any 2 of the 3 major operating systems (Windows, OS X and Linux) and start transferring files to and from external hard disk you will probably run into an issue with the type of filesystem you choose for your hard disk. Windows likes NTFS, OS X likes HFS and Linux likes ext. As you can see none of them are the same. Being different is not so much an issue, but being compatible and accessible to all is.

Based on default system settings:

• NTFS is readable on all operating systems, but not writable on OS X. Most modern Linux distributions can write to NTFS drives
• HFS is readable on OS X and modern Linux distributions, and not writable on Windows or Linux
• ext is only readable on Linux and not writable on Windows or OS X.

or to put it based on operating system

• Windows can only read and write to NTFS, nothing else
• OS X can read and write to HFS and read NTFS
• Linux can read and write to ext and NTFS and read HFS

Take note that there is also the older FAT32 filesystem that is fully supported for reading and writing by all operating systems but due to limitations of FAT32, I rather not consider this. Basically the main issues with FAT32 is that the maximum file size is 4GB and the maximum partition size is 32GB. If these are limitations you can deal with, for the sake for interoperability stick with FAT32.

Now to solve the problem of support for each filesystem in each operating system:

NTFS:

• OS X: NTFS-3G + MacFUSE
• Linux: NTFS-3G
• I’ve been using NTFS-3G in Linux for many years and haven’t had any problems with it and so far it’s working well with OS X too
• On another note if the NTFS drive is not unmounted properly or there are some issues with the file system integrity, it is necessary to use Windows scan disk to rectify the problem. Thus this requires a copy of Windows to fix the filesystem.

ext:

• Windows: Ext2 Installable File System for Windows
• OS X: Mac OS X Ext2 filesystem
• I’ve had issues of only being able to mount an ext2 partition in Linux and it gave a mount error in Windows and OS X and was due to an inode issue as new Linux distributions create the file system with inodes of 256 bytes but Ext2 fs only supports the older version with 128 bytes. And the only solution is to back up the files, and reformat partition with inodes of 128 bytes (-I 128) and restore the files.
• Filesystem integrity issues should be able to be fixed with “fsck” from a Linux distribution / live CD. The great thing about this is that you can get a Linux distribution for free and this recovery can be done with out any strings attached.

HFS:

• Windows: MacDrive (US$50, read and write), Paragon HFS for Windows (read only)
• Linux: Enabling HFS writing in Ubuntu
• Note: I have not personally tested these so I cannot give first hand experience of how well it works or what issues can be had with this.
• I believe that HFS+ journal
• I would believe any filesystem repairs would have to be done in OS X (similar to NTFS and Windows) and if so this enforces that you have OS X at hand, and in order to have OS X you must have Apple hardware or a Hackintosh either way this is very restrictive.

So it is pretty easy to get full read and write support of all 3 default file systems on the 3 major OS’s but there are issues. So far I’m inclined to stick with ext2/ext3 just due to the fact that it has no restrictions in terms of filesystem repair. I’ve had many NTFS issues related to damaged filesystems that required Windows and the inconvenience of taking the drive out of my box to find a Windows box was too much.

The year has started off great.

Kindergarten – We are learning the process for logging on. Once we are logged on we are learning the different tools in the Kid Pix application. This is a paint program that we will be using all year long.

First – We are starting the year off by learning how to type sentences and use some of the special characters such as ,?’. We are working on a book based on the book Brown Bear, Brown Bear, What Do You See?

Second through Sixth – We begin and end the year with keyboarding skills. The second and third graders are using Dance Mat Typing, which is online. This can be done at home also. Look for the Technology link at the right in the links. The fourth through sixth graders are using Ellsworth online keyboarding. This cannot be done at home since it is a book based program and we only have books at school.

Here’s a reader tech question from Robbyn:

Writing with a technical question, using my MacBook Pro I’ve been trying to copy a 4.93 GB .mov file to an external hard drive. Every time I try to do this I get an error message that reads: “Sorry, the operation could not be completed because an unexpected error occurred. (Error code 0)” I’ve tried zipping the file, but still have the same problem. I’m also not sure how to split up the file without having to convert it to another format which I’d rather not do since I’m sending it to someone to edit and I’d like to have it in the raw format so as not to lose any quality.

Well Robbyn, it sounds like an issue with the file system type on your external hard drive. Now I know you are wondering what that means so let me give you a quick overview:

Windows likes to format their partitions using one of their file systems, and Macs like to use their own. Unfortunately, they really don’t get along all that well. The only file system type that really works well on both Windows machines and Macs is FAT32. However, FAT32 has a bunch of issues including being pretty poor compared to other the newer formats, and more importantly, not supporting files over 4gb in size.

Unfortunately, you are trying to copy a big file, and big files not supported.. that’s probably the problem right there. Simple solution – check if it is formatted in FAT32 and reformat to HFS+ “non-case sensitive” because you that’s really unnecessary, and “non-journaled” because it tends to be more compatible, albeit slightly less secure in cases of drive failure. This will have some repercussions though, including all files will be deleted during the reformatting process and, as you might have guessed, HFS+ drives are not supported in Windows.

Now the other issue – the drive might be formatted using the NTFS file system, which is the one Microsoft currently employs for most Windows XP machines and all later operating systems.  And the issue with NTFS, it cannot inherently be written to by Macs.  Solution – same as above.  For big files, you need to use HFS+ for make your Mac fully support NTFS using some downloads from the Internet.  I would suggest, unless you need to be able to use your drive on both a Windows and a Mac, use HFS+.

In order to do all of this on a Mac, you can follow the following steps:

1. Open “Applications” in either your Finder, or on the Dock.
2. Find and click on the folder named “Utilities.”
3. In the “Utilities” folder you will find an application called “Disk Utility” – Open it.
4. You should see something like the image below.
5. Click on the drive you need to work on.
6. Change the file format using the “Volume Format” drop down in the center of the screen.

Please ask for clarification if you need any further guidance. Best of luck.

Salve a tutti mi scuso per l’assenza di nuovo, dovuta agli esami di stato, (a qualcosa è servito perchè mi sono diplomato con il massimo dei voti ihih) sto preparando tante novità e non macheranno belle guide, come appunto questa.. chi usa Mac avrà provato ad installare anche in dual boot Windows (non diciamo il contrario perchè è illegale) e avrà avuto la necessità di prelevare qualche file dalla partizione di Mac che però è formattata in Hfs e quindi non leggibile da windows. Scopriamo come risolvere questo problema senza alcuna spesa

Hace unas semanas le hice el Jailbreak al iPod Touch de un amigo, pero lo tuve que hacer en su computadora (Con Windows) y como no tenía mi memoria USB a la mano, usé mi disco duro externo para llevar los archivos que necesitaba.

Entonces recordé que mi HD tiene formato HFS, por lo tanto no podría usar mi HD en Windows, así es que me puse a buscar la forma de lograrlo y encontré algunos programas que permiten acceder a discos HFS o HFS+ desde Windows.

HFSExplorer

El primero de ellos y único gratuito es HFSExplorer, no cuenta con todas las opciones de los otros dos pero nos puede sacar de un apuro (Como a mi) en alguna ocasión. Este programa te permite visualizar los discos HFS, HFS+ y HFSX con un navegador gráfico, también podrás extraer archivos, ver información detallada del volumen y leer imágenes de disco con extensión .dmg.

Precio: Gratis

Descarga

MacDrive

El segundo y al parecer más completo es MacDrive, en este programa los HD son mostrados en Mi PC como si fuesen volúmenes compatibles, con un icono que los identifica, así que con MacDrive podrás trabajar con tus discos HFS (y derivados) como con cualquier otro.

Many students living on campus (and their parents) confuse the roles of the Housing and Food Services (HFS) office with that of Residence Life.  In order to clarify these roles, a comparison is warranted.

HFS is much more involved in the “nuts and bolts” issues of our on campus residential facilities.  Any maintenance work or any questions involving university-owned furniture or property should be forwarded to this office.  Students are encouraged to submit their own maintenance requests to the HFS office online here.  If someone can not access a computer, he/she may contact the office by calling (814) 898-6161 during business hours (M-F, 8AM-5PM) or (814) 898-6101 after business hours.  HFS also employs cleaning staff for each residence area on campus.  If a student lives in a suite-style building with their own bathroom, the staff will clean those, in addition to the usual tasks.

Residence Life, to put it simply, takes care of the people within the facility.  Residence Life staffs 47 resident assistants with a presence in each building in order to monitor safety/security issues, to guide residents to various resources within the community when needed, to serve as educators by providing interactive programming focusing on character development, and to mediate conflicts and act as counselors whenever necessary.  Resident assistants are supervised by coordinators who are live-in professional staff members working in the Division of Student Affairs.  Coordinators work with the RAs to plan much of the programming and to respond to any safety/security issues within the halls.  Coordinators will also meet with students who are suspected of violating community standards to determine responsibility and, if necessary, issue educationally-focused sanctions.

Today it’s the foundation for all modern pre-installed Windows systems. It replaced the aging FAT (File Allocation Table) file system with a leaner, meaner standard. It’s more secure, more flexible, and has more built-in gadgets than a Swiss Army Knife. It’s NTFS, of course — the New Technology File System.

I grew up with NTFS. I was there when it was introduced with Windows NT, and I insisted on reformatting every Windows machine I ever got my hands on — wiping out stuffy old FAT32 — with a file system so much more capable and pleasing. Yeah, OK, I was total nerd about the whole thing, I know.

So it came as something of a surprise to me that I didn’t think about file systems when I was switching to the Mac. And I didn’t think about file systems when I took a terabyte hard drive from my old PC and put it in my Mac Pro. And I didn’t think about file systems when I first clicked around that drive’s contents in Finder.

I did think about file systems when I tried to save changes I made to an old document that migrated to my Mac along with the drive. I was rewarded for my Saving efforts with an unwelcome dialogue telling me I couldn’t write to the drive. And then the penny dropped. My big, new shiny Mac Pro was using HFS+ while that second HDD was formatted with NTFS. And then I had to go and have a lie down for a bit due to an acronym-induced headache.

You’re unlikely to have experienced this access problem unless you have an external drive you like to use for both a Windows machine and a Mac.

Until Apple (s aapl) gets around to building full read/write compatibility into its operating system (and let’s not forget Snow Leopard is right around the corner) we have to find third-party solutions that cajole our hard drives into getting along with each other. One popular (and free) solution is NTFS-3G: a reasonably simple, though somewhat fiddly, application that requires users mount their NTFS drives/partitions in order to have full read/write access to the data stored therein. This can become cumbersome if an external drive is improperly unmounted on another machine. It’s not impossible to fix, mind you, but not effortless by any means.

If you need a simpler solution that offers transparent, and deceptively native, interoperability with NTFS formatted drives, you could try Paragon’s venerable (though horribly named) NTFS for Mac OS X 7.0 (or NTFSMOSX7 as I shall now refer to it because that string of characters is marginally less cumbersome than the full name).

NTFSMOSX7 is a small download, at a little under 3 megabytes and, once installed, ticks away in the background. There’s no user interface or settings to tweak. This really is nothing more than a driver.

If you buy the full version of the software, the download will undoubtedly be larger, since the paid-for app includes Paragon’s MacBrowser software for Windows. I might have tested MacBrowser for the purpose of this review, but Paragon never responded to my emails requesting more information, so if you have used it, and have an experience to share, please add a comment at the end of the article.

The only real problem I had once the hard drive was once again mine to use and abuse, was a conspicuous lack of Spotlight functionality. This is because, by default, Spotlight doesn’t index NTFS volumes. It’s not impossible to do, but it’s also not easy to achieve. The Spotlight preferences panel is typically spartan, so it’s necessary to bypass the Spotlight settings GUI and get your hands dirty in a Terminal session.

For those of you interested, by the way, the syntax for manually adding an NTFS volume (or any volume, for that matter) to Spotlight’s index via Terminal goes like this:

sudo mdutil -i on /Volume/VolumeName

Once entered, Spotlight will begin indexing your volume, which means it’s time for you to go watch some “Galactica” or “Big Bang Theory” while you wait.

A lot has been made of the apparent (and the not-even-remotely-important) differences between NTFS and HFS+. While HFS+ was ahead of the game at a time when too many Windows users were still mired in FAT (no jokes, please), NTFS was, and remains, a sophisticated file system. In fact, it bests HFS+ in many ways. Overall, though, is it better? I don’t know for sure, and I suspect for 99 percent of everyday users the question “who cares?” springs to mind.

Sidenote: Exuberant Apple supporters — aka Wailing Fanboys — muddy the waters with their auto-hate for anything not intrinsically Apple, claiming time and time again on discussion boards that “NTFS sux.” Occasionally, a particularly tech-savvy zealot will talk about comparing streams and counting data forks and probably even get into a debate over which Enterprise Captain is the best.

None of that matters so long as you can access your data quickly and painlessly, and, at least on the Mac, NTFSMOSX7 makes that possible. If you have to use NTFS volumes regularly but can’t reformat them to use HFS+, the $40 asking price for NTFSMOSX7 is perhaps not so steep in return for the convenience of seamless data interoperability. If, on the other hand, you want occasional quick-and-dirty access to an old NTFS volume and the ability to write data to it is not a serious concern, $40 is much too expensive for what amounts to a simple driver, and I’d suggest you stick with a free alternative.

You can try NTFSMOSX7 free for 10 days by downloading it from the Paragon web site. You can see which Enterprise captain is superior by clicking here.

Snow Leopard is starting to settle down into a relatively stable piece of software that will likely resemble the final release version, according to Engadget. Some speculate that it could receive retail release alongside iPhone OS 3.0 as soon as WWDC, which takes place in early June.

Like iPhone OS 3.0, Apple (s aapl) is now giving developers the go-ahead to develop Snow Leopard-specific apps without fear of major feature changes or revisions, since they just announced that the operating system’s APIs are now frozen. That should also mean that the feature list we’re seeing reported now from devs with access to the Snow Leopard beta is an accurate representation of what the new OS will ship with.

Some of the highly popularized features of Snow Leopard are the inclusion of QuickTime X, the long awaited update to the resident OS X media player software that will finally take it beyond version 7.xx. Another recent addition is Chinese character handwriting input recognition, a feature it borrows from its portable cousin, and a finished version of the Grand Central architecture, which lets devs use multiple processor cores without necessarily having the advanced programming knowledge usually required.

MacRumors points out yet another new feature they’ve spotted, which is the ability to access HFS+ formatted drives in Windows using drivers built into the new version of Boot Camp that will ship with Snow Leopard. The only people not pleased about that are probably the developers of MacDrive, a third-party Windows program which currently allows you to do the very same thing, but for a price. So long as Apple includes drivers for accessing NTFS drives in OS X, the circle will finally be complete.
