How to organize files based on date used

Most of us have our own unique methods for managing our files. Some of us love careful, hierarchical folder structures, while others prefer to stick with memory and search functions to keep track of documents. All too often, though, we need to find a file based on little more than a memory of accessing it last just before school started or just after the kickoff of some big project. Nemo is a file utility that uses a calendar structure to help you keep track of your documents more easily. Here's how to get started:

1. Install and run Nemo (for Linux or Windows XP and above).
2. Nemo begins indexing your files as soon as it's running, but you may want to tell it where to look if your documents are spread out across your hard drive (or in the cloud). Click the plus symbol next to "Folders" on the left side of the screen, then add or exclude any folders you like.
   

   Step 2: Add (or remove) folders.
3. You can add your Google documents and calendar items to Nemo easily--just select the "Google" tab and enter your username and password. (If your calendar is as overloaded as mine, you may want to deselect it from the list at the top left.)
   

   Step 3: Integrate with Google Docs and Calendar.
4. When you need to find a file, just scan through the calendar until you hit on the range of dates that seem likeliest to be when you used the file last. You can select particular file types to narrow down your search, and you might find that you prefer Nemo to your old file management system, at least for certain tasks.
   

   Step 4: Search for files.

That's how it works. Some users love Nemo's intuitive file management, while some can't get past its eccentric Friday-Saturday weekend setup. For those of us who need to find particular files quickly with little to go on but a range of dates, it's a lifesaver.

Kevin Mitnick shows how easy it is to hack a phone

British tabloid News of the World said today it is closing down over a phone hacking scandal in which workers for the Rupert Murdoch-owned newspaper allegedly snooped on voice mail messages left on the mobile phones of murder victims, as well as celebrities, politicians, and the British royal family.
If unethical journalists can do it chances are anyone can, right?
To test my theory I called up Kevin Mitnick, who wrote about the hacking and social engineering that landed him in jail in a fascinating book coming out this summer, "Ghost in the Wires," and who serves as a security consultant, helping clients protect against privacy breaches such as this.
Phone hacking, also known as "phreaking," is easy to do, Mitnick said, adding that he could demonstrate it on my phone if I wanted proof. So I gave him permission to access my voice mail and told him my mobile phone number.
He called me right back on a conference call so I could hear what was going on. First he dialed a number to a system he uses for such demonstration purposes and entered a PIN. Then he was prompted to enter the area code and phone number that he wanted to call (mine) and the number he wanted to be identified as calling from (again mine). Next thing I know I'm listening to a voice message a friend of mine left me last night that I hadn't erased.
"See how easy it is?!" Mitnick says as my jaw drops.
He was able to get into my voice mail by tricking my mobile operator's equipment into registering the call as coming from the handset--basically pretending to be me. To do this, he wrote a script using open-source telecom software and used a voice-over-IP provider that allows him to set caller ID, but there also are online services that provide similar capability that non-hackers could subscribe to. It might be easier or harder to accomplish depending on the mobile operator, he said. (I'm keeping some of the details sketchy to avoid providing a how-to for phreaking.)
"Any 15-year-old that knows how to write a simple script can find a VoIP provider that spoofs caller ID and set this up in about 30 minutes," Mitnick said. "If you're not adept at programming, you could use a spoofing service and pay for it."
This technique, called Caller ID Spoofing, has been used and abused for years. In 2006, a caller ID spoofing account in the name of Paris Hilton was suspended for voicemail hacking, with other celebrities, including Lindsay Lohan, allegedly being victims, according to IDG News Service.
The method is more sophisticated than that allegedly used by the British journalists who are accused of using default PINs to access victims' voicemail accounts, assuming correctly that many people wouldn't bother to change the PINs. Since the phone hacking scandal first erupted about five years ago, mobile operators in the U.K. have changed their practices and most now require people to set their own PINs for remotely checking voice mail.
If I want to avoid having anyone use Caller ID Spoofing to access my voice mail again, I need to change my phone settings to require a PIN even when checking voice mail from my mobile device. But that doesn't address the fact that mobile operators don't authenticate caller ID. "The magic is that my VoIP provider allows me to set any caller ID and the other operators trust it," Mitnick said. "Caller ID is automatically trusted."
Mobile phone industry specialist David Rogers suggests on his blog that operators should consider preventing people from accessing mobile voicemails remotely at all.
Meanwhile, the Truth in Caller ID Act of 2010, which was signed into law late last year, prohibits anyone intending to defraud, cause harm, or wrongfully obtain anything of value from knowingly causing any caller ID service to transmit or display misleading or inaccurate caller ID information. This could send the caller spoofing services off shore but likely won't put an end to the practice.
