PowerShell Tutorial

Suppose you know a little bit about Linux, which provides a very rich command interface. Because of Linux rich command, Linux was a preferred platform for software development. On the other hand, windows was mostly used for UI-based uses for non-development purposes. So finally, to control all these issues, Microsoft released PowerShell version 1 for the first time in 2006. The main goal of PowerShell was to provide command rich interface to developers where developers will be able to write scripts and automate various jobs. So initially, they developed PowerShell for Windows only, but after version 6, it started supporting macOS and Linux as well.

Why do we need to learn PowerShell?

In Windows, it has DOS cmd, But if we need to do complex scripting and if we need to write any heavy scripts jobs, then the existing cmd is not good enough. PowerShell allows developers on Windows to write a script with controlling one computer to multiple remote computers at once. DOS is just a shell where PowerShell is a powerful scripting language that is completely based on .NET and is mostly used by my administrator to handle Networks and servers. On Windows, if you use DOS as cmd, you will be only checking ipconfig and some basic things, whereas by learning PowerShell, you will be a complete programmer. Because of its rich commands and object-based approach, it is a powerful tool for scripting.

Below are some points why we should learn PowerShell.

Consistency: The biggest benefit of PowerShell of the current version is that it is available for all Operating systems. So, for example, if you are developing the script on a computer X and after successfully testing your script on your computer X, you can share your script with another person who is going to run your script on his computer Y, which will work perfectly from the version 6 because PowerShell is available for all OS, ie. Windows, Linux, and macOS. So a script will work on different architecture as well. Other than Architecture, PowerShell also provides automation to administration tasks with better performance .

Interactive and scripting environments: The Powershell of Windows Prompt gives us a very interactive tool to access the command-line interface for scripting.

Object orientation: As it is totally written over the .NET, it will give us a complete Object-based approach to implementing it. So we are not just writing a command. It allows us to explore more.

Applications of PowerShell

It will be very useful for administrative management with PowerShell admin to delete, add and update users. We transfer heavy files from one computer to another to multiple network computers at once. If Admin has some task that he will run repetitively, then the Admin can use PowerShell to create a script and put it into job cycles where it will run at given intervals.


Suppose, In PowerShell, we want to see the process with name “nginx” and “node.”


You can install Powershell by MSI, and you should only need to learn the basics of programming like, if, for loops and variables and it’s an available rich set of commands. Even if you do not know much programming you can directly start with PowerShell.

Target Audience

Developers: A developer can have requirements to develop a tool where he may change his data for a running application regularly. For example, on any e-commerce website, we want to show the best-selling products. So the developer will write a script that will fetch data daily and update top-selling product details so that top-selling products will be visible to end customers.

Administrator: The administrator can write a script for automation of updating, deleting, and performing certain tasks on all the users regularly to avoid repetition of the same tasks.

Why Do We Need Selections In Photoshop?

None of this, however, explains why we need to make selections in the first place, so in this tutorial, we’ll take a quick look at the “why”. This won’t be a detailed explanation of how to make selections. We’ll save that for other tutorials. Here, we’re simply going to look at why we need to make selections at all.

Take selections in Photoshop, for example. There’s no shortage of ways to select things in an image with Photoshop. We can make simple geometric selections with the Rectangular Marquee Tool or the Elliptical Marquee Tool , or freehand selections with the Lasso , Polygonal Lasso or Magnetic Lasso Tools. We can select areas of similar color or brightness values with the Magic Wand or Color Range command. We can paint or refine a selection manually with a brush in Quick Mask mode or by using a layer mask. We can make surgically-precise selections with the Pen Tool , and more! We can even combine different selection methods when none of them by themselves seem to be up to the challenge.

As you may have already discovered on your own if you’ve read through any of our other Photoshop tutorials here at Photoshop Essentials, I’m a big fan of “why”. Lots of people will happily tell us how to do something, but for whatever reason, the why is usually left out, forever limiting our understanding of what it is we’re doing.

Do You See What I See?

As I write this, summer is once again coming to an end. The days are getting shorter, the nights are cooler, and around here, with autumn fast approaching, the weekend farmers markets will soon be filled with bushels and bushels of apples. In fact, here’s some right now just waiting to be picked:

Red, delicious apples. Unless of course, you don’t like apples, but who doesn’t like apples?

Obviously, the main subject in the photo above is the apples, right? But why is it obvious? How do we know that we’re looking at apples? We know because most of us have seen enough apples in the past that we can instantly recognize them. We know their shape, their color and their texture because we’ve seen them before. We could even point to each apple in the photo if someone asked us to without mistakenly pointing at a leaf or something else that isn’t an apple because we have no problem distinguishing between all the different objects in the image. We see things with our eyes and our brain tells us that this is this and that is that, and this is not that and that is not this. In fact, even if we had never seen an apple before, we could at least point to all the objects that look relatively the same. We’re so good at recognizing and identifying objects that we usually do it without consciously thinking about it.

That’s great for us, but what about Photoshop? Does Photoshop see the apples? Does Photoshop recognize their shape, color and texture as “apple”? Can it point to all the apples in the photo without confusing an apple with a leaf, or at least point to all the objects that look the same?

The simple answer is no, it can’t. No matter how many photos of apples you’ve opened in Photoshop in the past (geez, what is it with you and apples?), Photoshop has no idea what apples are or what they look like. The reason is because all Photoshop sees is pixels. It doesn’t matter if it’s a photo of apples, oranges or monkeys eating bananas. To Photoshop, it’s all the same. It’s all just pixels, those tiny little squares that make up a digital photo:

A close-up view of the edge of an apple showing that it’s really just a bunch of tiny square pixels.

Select None To Select Them All

So far, we know that we see things very differently from how Photoshop sees them. We see independent, recognizable objects while Photoshop sees everything as pixels, and we tell Photoshop which pixels we want to work on by selecting them with one or more of the various selection tools. In fact, before we can do anything at all to an image, Photoshop first needs to know which pixels we want to edit.

For example, let’s say I want to change the color of the main apple in the photo. I want to change it from red to green. Based on what I just said, I shouldn’t be able to do that without first selecting the pixels that make up the apple. Let’s give it a try anyway, just for fun. I’ll select the Brush Tool from the Tools panel:

Selecting the Brush Tool.

Photoshop paints with the current Foreground color.

The Color Picker is the most common way to select colors in Photoshop.

Ultra-realistic photo effect. Expert users only.

Wait a minute, what just happened?! I was able to paint over the apple! Photoshop didn’t complain at all! Okay, let’s recap. I said we can’t do anything to an image unless we first select the pixels that we want to edit. Then to prove it, I grabbed my Brush Tool and tried painting over part of the image without first selecting anything, yet I was still able to paint over it. This can only mean one thing… I have no idea what I’m talking about!

Seriously though, the real reason why I was still able to paint over the apple without first selecting any pixels is because of a little known fact. Whenever we have nothing selected in an image, we actually have everything selected. Photoshop assumes that if we didn’t select any specific pixels first, it can only be because we wanted every pixel selected so we can edit the entire photo. Or at least, we have the option to edit the entire photo. As we saw in this example, I was able to paint over just a small area of the image even though I didn’t select any pixels first, but if I wanted to, I could have just as easily painted over the entire image and there would have been nothing preventing me from doing that.

While having the freedom to go where we want and do what we please sounds wonderful, it can actually be a very bad thing, at least when it comes to photo editing. In this example, all I wanted to do was change the color of the apple, yet because I didn’t select the apple first, Photoshop allowed me to paint anywhere I wanted, and all I ended up doing was making a mess of things. Let’s see what happens if I select the apple first.

Painting Inside The Lines

I’m going to undo the paint strokes I added to the image by pressing Ctrl+Z (Win) / Command+Z (Mac), and this time, I’ll select the apple first before painting over it. As I mentioned at the beginning of this tutorial, we’ll save the details of how to actually make selections for other tutorials. For now, I’ll simply go ahead and draw a selection around the apple.

Photoshop displays selection outlines for us as a series of animated dashed lines, or what many people call “marching ants”. Obviously, we can’t see them “marching” in the screenshot, but we can at least see the selection outline that now appears around the apple:

Selection outlines appear as animated “marching ants”.

Of course, to us, it looks like I’ve selected the apple, but keep in mind that as far as Photoshop is concerned, all I’ve done is selected some of the pixels in the image. They just happen to be the pixels that make up what you and I see as an apple. The pixels that fall within the boundaries of the selection outline are now selected, which means that they can be affected by whatever edits I make next, while the remaining pixels outside of the selection outline are not selected and won’t be affected by anything I do.

Let’s see what happens now when I try painting over the apple again. I’ll grab the Brush Tool just like I did before, and with green still as my Foreground color, I’ll try painting over the apple. The only difference this time is that I selected the apple first:

The paint strokes now appear only inside the selected area.

Thanks to the selection I made before painting, Photoshop allowed me to paint only inside my selected area. Even though I moved the brush well outside the boundaries of the selection as I was painting and made no attempt to stay inside the lines, none of the pixels outside of the selection outline were affected. They remained safe and unharmed no matter how sloppy I was with the brush, and I was able to easily paint over the apple without worrying about the rest of the image, all thanks to my selection!

Of course, just because we’ve selected a certain area of pixels doesn’t mean we necessarily have to edit every pixel inside the selection outline. I’m going to once again remove my green paint strokes by pressing Ctrl+Z (Win) / Command+Z (Mac) to undo the last step, and this time, with my selection still active, I’m going to use a much larger brush with soft edges to paint only along the bottom half of the apple, giving me a nice transition in the middle between the green brush color and the natural red of the apple. Even though the pixels in the top half of the apple are part of the selection I made, they remain unchanged because I chose not to paint over them. Photoshop doesn’t actually care if we do anything with the pixels we’ve selected. All it cares about is that we don’t get to touch the pixels we didn’t select:

Any pixel inside of a selection outline can be edited, but nothing says you have to edit every pixel.

Just as before, my paint stroke is confined to the pixels inside of the selection outline, even though I moved well outside of it with my brush. To make things look a bit more realistic, I’m going to blend the green color in with the apple using one of Photoshop’s blend modes. I’ll go up to the Edit menu at the top of the screen and choose the Fade Brush Tool option:

The actual name of the Fade option changes depending on the last edit that was made.

This brings up Photoshop’s Fade dialog box, which allows us to make some adjustments to the previous edit. To blend the green in with the apple, I’m going to change the blend mode of the brush to Color, and to lower the intensity of the green, I’ll lower the Opacity option down to around 80%:

The Color blend mode allows us to change the color of an object without changing its original brightness values.

Press Ctrl+H (Win) / Command+H (Mac) to temporarily hide selection outlines. Press it again to bring them back.

Up next, we’ll look at another important reason for making selections – working with layers!

Selections Make Layers More Useful

Up until now, I’ve been making all of my edits directly on the Background layer, which is a very bad way to work because it means that I’ve been making changes to my original photo. If I was to save my changes and close out of the document window, the original image would be lost forever. Sometimes that may be fine, but it tends to leave a bad impression when you’re forced to call up a client and ask, “Would you happen to have another copy of the photo you sent over? I sort of… well, hehe… I kind of ruined the copy you gave me”.

A much better way to work in Photoshop is to use layers. With layers, we can work on a copy of the image while leaving the original unharmed, and thanks to selections, we can even copy different parts of an image to their own layers so we can work on them independently! Without the ability to make selections though, layers in Photoshop would be nowhere near as useful as they are.

I’m going to revert my image back to its original, unedited state by going up to the File menu and choosing Revert. This sets my image back to the way it was when I first opened it:

The Revert command reverts an image back to its original state or to the last saved state.

A very common Photoshop effect is to leave something in the image in full color while converting the rest of the photo to black and white. Let’s see how selections can help us to do this. First, since we just said that working directly on the Background layer is a bad thing, let’s duplicate the Background layer, which will give us a copy of it that we can work on. To do that, I’ll go up to the Layer menu at the top of the screen, then I’ll choose New, and then I’ll choose Layer via Copy:

Creating a copy of the original image.

If we look in the Layers panel, we can see that we now have two layers – the Background layer on the bottom which holds the original photo, and a new layer above it which Photoshop has named “Layer 1”, containing a copy of the photo that we can safely edit without harming the original:

Working on a copy of the image keeps the original safe.

Notice that the entire Background layer was copied. We’ll come back to this in a moment. Since we want to leave the apple with its original colors while converting everything else to black and white, we’ll need to select the apple before we do anything else, so I’ll once again draw a selection around it. Our familiar selection outline reappears:

A selection outline appears once again around the apple.

With the apple selected, I’m going to create another copy of the image by going back up to the Layer menu, choosing New and then choosing Layer via Copy. Remember that the last time we did this, Photoshop copied the entire layer. This time though, something different has happened. We now have a third layer in the Layers panel sitting above “Layer 1” and the Background layer, but if we look in the preview thumbnail to the left of the new layer’s name, we can see that all we copied this time was the apple itself, not the entire layer:

True to its name, the preview thumbnail gives us a preview of the contents of each layer.

Any time we have a selection active when we copy a layer, only the area inside the selection outline is copied, which is why in this case, only the apple was copied. This ability to isolate a specific object in a photo and place it on its own layer is what makes layers so incredibly useful. If we couldn’t select anything first, all we could do is make copy after copy of the entire image, which is usually about as pointless as it sounds.

Selected layers appear highlighted in blue.

To convert the image to black and white, I’ll quickly desaturate it by going up to the Image menu, choosing Adjustments and then choosing Desaturate:

The Desaturate command is a quick way to remove color from an image.

Desaturating an image is certainly not the best way to convert a color photo to black and white, but it works in a hurry. Let’s look again in the Layers panel, where we can see in the preview thumbnail for “Layer 1” that the copy of our original image now appears in black and white, while the apple on the layer above it has been unaffected and remains in color:

Only “Layer 1” has been desaturated.

Since the apple is sitting on a layer above the black and white version of the image, it appears in full color in front of the black and white image in the document window:

Combining selections with layers makes a great creative team.

Of course, there’s a lot more we can do with selections in Photoshop than just painting inside of them or copying them to new layers, but hopefully this gave us an idea of why selections are so important. Photoshop sees only pixels where we see independent objects, so we need selections as a way to bridge the gap between our world and Photoshop’s world. And while layers can stake their claim as one of the biggest and best features of Photoshop, they owe more of their usefulness to selections than they’d probably care to admit.

Learn The Various Methods Of Powershell Join

Introduction to PowerShell Join

The join cmdlet is used to join multiple strings into a single string. The order in which the multiple strings are retained during the concatenation operation is the same order in which they are passed to the cmdlet. Join cmdlet is also used to covert text that is present in pipeline objects into a single string value. This article will explain in detail about join cmdlet in PowerShell, its syntax and usage along with appropriate examples.

The basic syntax of the join operator is as follows

Where string1, string2 and string3 represent the various strings that needs to be merged. The delimiter represents the character that should be present between the strings that are concatenated. If no value is specified, the “” is used by PowerShell.

The following are the other available syntax

For the Join-String cmdlet, the default separator that is used by PowerShell is $OFS if the user doesn’t specify any value. If a property name is specified, then that property’s value can be converted to a string and subsequently concatenated to a string. A script block can also be used in place of a property name. If that is done, then the script block’s result is converted to a string before concatenation. This cmdlet is the latest and was released as part of PowerShell version 6.2

When the comma has used a delimiter with the join operator, the join operator is given a higher priority. In that case, only the first string is considered, in order to avoid that the strings must be enclosed in parentheses.







This parameter is used to encapsulate each pipeline objects string value inside double quotes. The datatype of this parameter is switch and its default value is false. This parameter doesn’t accept pipeline input and wildcard characters are also not accepted.


This denotes the format structure of the item. The datatype of this parameter is string. None is the default value of this parameter. This parameter doesn’t accept pipeline input and wildcard characters are also not accepted. This is an optional parameter.


This denotes the input texts that are to be joined. It can either be a variable or a command object. The datatype of this parameter is PSObject[]. This parameter’s default value is none. This parameter accepts pipeline input whereas wildcard characters are not allowed. This is an optional parameter.


This denotes the text that will be inserted before the result. It can contain special characters such as newline or a tab. The datatype of this parameter is string. It can be referred using its alias, op. None is the default value of this parameter. This parameter doesn’t accept pipeline input and wildcard characters are also not accepted. This is an optional parameter.


This denotes the text that will be inserted after the result. . It can contain special characters such as newline or a tab. The datatype of this parameter is string. It can be referred using its alias, os. None is the default value of this parameter. This parameter doesn’t accept pipeline input and wildcard characters are also not accepted. This is an optional parameter.



This denotes the character that needs to be inserted between the  text that are joined from the pipeline object. It is generally a comma(,) or a semicolon (; ). It is placed at the number one position. None is its default value. Both pipeline input and wild card characters aren’t accepted. This is a mandatory parameter.


This parameter is used to wrap the output string value from pipeline object inside single quote. Its datatype is switch. None is its default value. Both pipeline input and wild card characters aren’t accepted. This is an optional parameter.


This uses the current culture’s separator as the value of the item delimiter. To find this information, Get-Culture).TextInfo.ListSeparator is used. The datatype of this parameter is switch. None is its default value. Both pipeline input and wild card characters aren’t accepted. This is an optional parameter.

What Is Onedrive And Why Do I Need It?

You must have noticed by now, the faster and more popular SSDs come in much smaller capacities than the older hard disks. Moreover, people prefer these smaller sized SSDs than buying slower HDDs. Two things come to mind as to why this may be happening.

First, the speed benefits of SSDs outperform the storage capacities, leading to many users going for a hybrid setup with both storage types. Secondly, people do not need to store their frequently accessed files locally, as cloud storage gains popularity.

Here, I shall be discussing what is OneDrive and why do you need it on your computer.

Similar to your local storage, you can store all kinds of files and folders in OneDrive. The added benefit to this is that you can access these files from all the devices that you own, using your login credentials. Works wonder if you need to work on a file on the go, you can start the work on one of your devices and later pick right where you left on another.

Being a Microsoft product, Windows 10 users get additional benefits as well. These include seamless integration with your Office product to allow sharing and collaborating with other users, syncing your Windows settings across all your devices.

One of the benefits of using cloud storage is that cloud storage acts as your backup system. Thus, if your hardware device gets damaged due to some reason, you can safely recover your files from OneDrive. Extend this to storing your BitLocker or other file encryption recovery keys, and you will virtually never lose data (unless your subscription expires, or your Microsoft account is hacked).

If you want to use OneDrive on your devices, you will first need a Microsoft account. If you do not already have one, you can create an account on the OneDrive website as well.

When you sign up for Microsoft OneDrive, you get 5 GB of online storage for free. This should be enough if you have plenty of onboard storage and only want to keep some important files on the go. To create an account, follow these steps:

Open the OneDrive web page from your web browser of choice.

Sign up for free

Create a Microsoft Account, by entering your credentials and following the on-screen instructions.

Once you have signed up, you will be automatically redirected to the OneDrive website, where you will be able to see the files currently on your online storage.

Note: If you already have a Microsoft account, you need to sign in to your account, which is already connected to an OneDrive account as well.

Once you have your account set up, you can now set up the OneDrive folder on your computer as well. This folder can be used to access the files on your online storage account, and quickly add or remove files as well. New Windows 10 installations usually come with the OneDrive application already installed, so follow these steps to set up the folder:

Simply open Windows Search by pressing the Windows key on your keyboard.

You can also access this file from the left pane context menu in File Explorer.

Note: If you do not have OneDrive installed, you can download the app from the Microsoft Store or by using this direct download link.

The answer to this depends on your usage, and how ready you want to be with your files. If you find yourself constantly working on the go, or between multiple devices, you may benefit a lot from online storage. You can have all your important files virtually with you wherever you go.

When you sign up for Office 365, you get 1 TB storage, which you can utilize if you only have limited storage (128 GB or 256 GB SSDs as local storage) on your computer.

However, if you have plenty of onboard storage and do not want to utilize cloud storage, you can uninstall OneDrive from your computer. Follow these steps for the same:

This will open the Apps section of the Settings app.

Follow the onscreen instructions and restart the computer once done, and you will have removed OneDrive from your computer.

So, there you have it. Now you know what OneDrive is and why you need it, and how does OneDrive work on your Windows 10 computer. Comment below if you found this useful, and to discuss further the same.

Do Developers Need To Brown

“You are SUCH a brown-noser!”


That was probably the least flattering thing I had been called. Maybe even worse than being called an idiot.

I’m sure any developer would have done the same thing. Actually, maybe not. But they should! I’ll let you be the judge.

Here’s what happened. I had just returned from a meeting with the CIO. Yep, a little ‘ol developer like me had requested a face-to-face with the big dog. I found over the years that it is so true that the squeaky wheel gets the grease. Therefore, I went out of my way to be squeaky.

I had a few years of coding under my belt and was just starting to take some graduate classes. One of the hot topics in class was telecommuting – especially for technology workers.

I thought “Gee, why shouldn’t every developer be able to telecommute?”

So I emailed the CIO directly and just like that I had my meeting scheduled – just that simple. You’d think the CIO gets tons of emails from employees with suggestions. I have found that is not the case. And that doesn’t just apply to the CIO, but also to others in management.

Yay! I was excited. So when I came back to my cubicle, I couldn’t wait to tell everyone. I mean, they could be no less than thrilled that I was pushing forward such a great perk that would benefit us all.

That’s when I learned that while it is true that speaking out and coming up with ideas are typically welcomed by managers, it is also true that these actions can be perceived by co-workers as being overly obsequious (i.e. too much sucking up to the boss).

(I must admit the definition of this term is quite humorous, but I digress…)

Sorry, but I don’t see it that way at all. If you have a great idea, why keep it to yourself? Some developers have told me that it’s their job to write code, not to propose methods for fixing the organization.


To me that line of thinking belittles developers. If an organization is going to improve, ideas need to come from chúng tôi course you can’t spend all your time idea mongering, but as long as your development work is being performed well, why not use your brain to noodle on different and new ideas? And then share those ideas!

Ah, but then you may open yourself to the same accusations of having ulterior, self-serving motives. But guess what?

Who cares!

Because even if speaking up with fresh approaches is self-serving and helps you climb the career ladder faster, what does it matter if you are improving the organization?

True, if you’re truly sucking up just to get your name and face in front of management, then your scheming will be smelled a mile away. Your ideas must have value or you’re just making a fool of yourself and wasting everyone’s time.

The “Fool” Aspect

Let me delve into the “don’t make a fool of yourself” caveat a bit deeper.

We Need To Rethink Pc Security Software

The security software scene is a mess. In order to keep programs that carry with them bad intentions off our PCs we turn to programs that cause no end of problems – and which slow systems down to the pace of a hyperactive snail.

And instead of getting better, things are getting worse.

I remember a time when PCs didn’t need any protection at all, and even when the first viruses hit the scene, protection came from practicing safe sectors and putting a little bit of tape over the write protect notch on 5.25 inch floppy disks. But then, at around the end of the 1980s things started to get more complicated.

In recent years antivirus applications have become out-of-control monsters, devouring free system resources. But if it stopped with just needing to have protection against viruses, things wouldn’t be too bad. Problem is, viruses are only part of the problems.

Nowadays we are told (mostly by firms selling security products) that we need protection against all sorts of threats – adware, spyware, spam. On top of all that we’re supposed to run firewalls and carry out deep scans of our systems on a regular basis. This not only represents a lot of money, installing and updating this software is a lot of work.

But to top it all off, all these programs running can make a new PC feel old, really fast. In fact, I know several people who bought new PCs because their old one was slow only to discover that the new system became just as sluggish once all the protection was loaded onto it.

Now, don’t get me wrong. I know that you can’t get something for nothing, and scanning all the packets that flow to and from your PC, along with all the files and applications that are accessed, isn’t a trivial workload. I don’t expect all this work to be done with no overhead at all, but given the drag of performance that almost all the current suite of security products have on PCs, something is drastically wrong somewhere. Any software that runs in the background is going to have an effect on performance; I just don’t think it should have as much of an effect as it has.

But the problems go much deeper than performance issues. Over the past few years I’ve noticed a disturbing trend where security software is constantly clamoring for your attention – telling you that updates are needed, that updates have been installed, that your system is protected, that your system needs more protection, that your system has been scanned, that you’ve sent an email, that you’ve received an email.

In fact, I’m amazed just how many prompts and messages a security suite can generate. The only message that I’ve yet to see is that the program has done its job and caught some nasty bit of code trying to get a foothold into my system.

I’m guessing that the reason for the vocal nature of security software is that it wants to keep reminding the user that it’s there so that come time to renew the subscription, the user actually pays up for another year. And now we have reputable security firms such as Lavasoft, now in talks with Ask to bundle toolbars with the application. Yeah, let’s burden the user’s PCs further with unwanted junk.

Does it have to be like this?

Well, yes and no. While it’s possible to shift a fair amount of the security workload off individual PCs and onto routers and hardware firewall devices, this still leaves systems open to infections via CDs, DVDs and flash-based devices. While it’s true that the Internet represents the greatest threat (and when you have employees spending time in the darker, seedier corners of cyberspace that threat is much greater), you can’t overlook the risks that USB keys and iPods represents.

My take on the situation is that security companies have done a good job of convincing people that their products are essential if you are to keep your system free of badware (that’s not true, but I’m not going to get into that argument right now), and as such the incentive to develop a good, solid product is lost. The fact is that there isn’t a single product that stands out as being better than the others; instead, they’re more trying to maintain the status quo (or stagnation).

I’ve gotten to the point where I think I’d rather take my chances with the bad guys myself rather than bother with so-called security software.
