Why doesn't my new, empty hard drive show all the advertised space?
I just purchased a new computer with a 1TB (terabyte) hard drive. Windows is telling me it has 976,760,000KB of disk space. I don't get it. Shouldn't it be 1,000,000,000KB? Is there anything I can do to recover the other space? If I go to Windows Explorer and click on the hard drive symbol, it will show me the space on the hard drive. It said the total available space is 931 GB! What happened to the other 69 gigabytes?
They were never there.
Believe it or not, there's no real, agreed upon definition of what a gigabytes is.
Let me clarify: there are definitions. Plural. And which one gets used depends on ... well, it depends on how you think.

How do I find out who's sending me this harassing
I am sorry that the resources for this kind of thing are so limited... because unfortunately, online harassment and cyber bullying are very common.

Why did my PDF print with two additional pages of
One of the very first things that I would be concerned about is your print-to-PDF technology. I'd be concerned that it was downloaded from a questionable site.

Can you recommend an anti-virus tool that will work in a 256MB
The fact is 256 MB is not sufficient to run any of the current operating systems. That means that you're in a difficult place.

My machine is slow and unstable. What do I do?
Depending on the age of this machine, it is possible that your machine is simply trying to run too much software.

Is my browser tracking me?
Yes, and no. Logging into Chrome allows you to use your settings on other computers. Your browsing history is another matter.

How do I get my browser to download where I want it to by
This is a very common setting, so there should be good information in the browser's help guides to assist you in changing the download default.

My machine won't finish booting. What do I do?
Ultimately, I'm concerned that you may end up needing to see a technician who can take a look at the machine hands on.

Could a technician discover my browsing history from seven years
A technician certainly could stumble across this. But if they're looking at deleted files and that's not part of what they're trying to recover? To me, that's unethical.

Is there a reference of what services I need running on my
Microsoft isn't trying to run a bunch of software on your machine that you don't need. If anything, it's the applications that come along later that do so.

How do I stop spam?
The practical reality is that you can't stop spam. The best that you can do is deal with it as efficiently as possible using the technologies that you have in your hands today.

Well, your theory of 'mouse key(?) stroke logger' sounds scary, but there is no known software to do that correctly. Mouse's motion is far more complicated than key board.
It's easier than you think. You don't need to record the mouse movement, only the position it is at when clicked, and a screen capture at the same time. All very, very easy.
You have just purchased the Ultimate anti-virus machine on the planet. I've owned a Mac laptop for 6 years now. It is still going strong and fast, and the best part is...I've never had a virus. Ever.
Neither has my wife, who's used PC's exclusively - for years - until now. I don't want to minimize your pride, but I am concerned that the Mac community in general has become too used to this myth that Macs don't get viruses. They can and do. They're not as big a target as Windows, but it has begun to happen. Even Apple was forced to remove the "it doesn't get viruses" from their marketing materials this year.

The worrying thing is that if they restrict the types of character or the
length then it implies they are storing your password "in the clear". I.e. they
are storing a copy of your password in their database in a human readable
format. If their database is compromised then so is your password. If you
happen to use that password on other systems then that has also been
compromised. They should 'hash' the password. 'Hashing' is applying a
transformation to the password to turn it into a very very long string of
characters and store that string in their database. When you subsequently log
in with your password the same transformation is applied and compared to the
answer. If the database is compromised the 'bad guys' only have your hash - if
they use that as your password it will always fail.
Even this isn't totally secure so the best system includes adding 'salt' to the hash. This prevents 'rainbow' attacks. The first step is to stop storing passwords in the clear and it is really disappointing that Microsoft have not upgraded Hotmail's security since they bought it years ago. To answer the question (and to re-enforce Leo's answer) the ISPs don't allow these characters because their security is lapse!
I don't believe that these limitations imply that the system is storing the password in plain text. There may be other limitations in their architecture - between password acceptance and eventual storage - that impose these length and character set limitations. You're correct that salted hashes are the proper way to do this, but I believe that the only way to determine whether a password is kept in plain text is to perform a password retrieval - if they can tell you your password, then they have it in plain text. If they don't (i.e. they only allow you to set a new password) then no assumptions can or should be made.

The problem is, sending me an email may be an imposition. Certainly I may see it as such. Asking for me to confirm that I have seen it, is a further imposition.
On a personal level, if we're friends, I will confirm that I've seen it or be prepared to cause an issue.
On a business level I would *NEVER* confirm receipt, if I didn't in any case wish to reply.
If your communication is such that you feel you're owed a reply, then call me. Don't send me an email and dump the communication care responsibility on me.

Seagate FreeAgent Go - Portable USB External Harddrive
I currently own five of these.
If that isn't a recommendation I don't know what is.
One of the problems with recommending a specific disk drive is that drives change, capacities increase and what I might tell you about today may not even be available next year. The external drive I recommended some years ago is no longer even being made.
With that having been said, today the FreeAgent Go is an incredibly handy and valuable device.
The version I use has a capacity of 500 Gigabytes, all in a package that's smaller than a paperback book.
