Freewaregenius

Sunday, March 25th, 2007

This is an invaluable site that reviews numerous freeware apps.

My mission: To replace as many retail/shareware software as I can with first rate FREEWARE alternatives, such that one day every installed program that I use will be FREE.

But this site will not list every single free program on the planet. Sometimes less is more!

I assume that for every category there are one or two programs that anybody would want to use. This site will present you with these handful of options, filtered and picked out.

If you have better things to do than scour the web for cracks, serials, and hacked copies of the software you use, then this site is for you, because the free software that is presented here is in most cases BETTER than anything you could pay for.

Viktor’s Amazing 4-bit Processor

Wednesday, March 21st, 2007

This is an impressive feat: designing and building your own processor.

Viktor’s Amazing 4-bit Processor

I’ve been a software guy all my life. However, I was always fascinated by electronics, and part of my success as a programmer was due to my thorough understanding of how computers work.

Back in 1999, I put that understanding to the ultimate test: I actually designed, and built, a simple but functional 4-bit computer from low-level electronic components (TTL logic gates.) Although this machine has less then one tenth of a percent of the speed and one millionth of the memory of a modern Pentium system, not to mention that its “user interface” is just a set of miniature switches and blinking LED lights, I still consider this a proud accomplishment.

Downloads: TrueCrypt 4.3 (Windows, Linux)

Tuesday, March 20th, 2007

The latest update to the TrueCrypt encryption utility is now available.

We are pleased to announce that TrueCrypt 4.3 has been released. Among the new features is full compatibility with 32-bit and 64-bit Windows Vista, support for devices and file systems that use a sector size other than 512 bytes (such as new hard drives, USB flash drives, DVD-RAM, MP3 players, etc.), auto-dismount when a host device (e.g., a USB flash drive) is inadvertently removed, and many more. In addition to new features, there are many significant improvements. Some portions of the TrueCrypt device driver have been completely redesigned and several bugs have been fixed. For a comprehensive list of changes, please see http://www.truecrypt.org/docs/?s=version-history

The Lockdown

Monday, March 19th, 2007

Engadget has a fascinating series of articles on lock security and lock picking.

The most popular locking mechanism in the world utilizes the pin tumbler design, first developed 4000 years ago in Egypt and then rediscovered and perfected a century and a half ago by Linus Yale. There are billions of these locks in the world and they come in all sizes, configurations, and security ratings. Some are secure; most are not, and even some high security rated cylinders can be easily compromised. All that is required to open many times of pin tumbler cylinders — the kind of lock that probably keeps the bad guys out of your home — is a bump key and a tool for creating a bit of force. The bump key shown above opens an extremely popular five pin lock, and the plastic bumping tool is produced by Peterson manufacturing, although many others are now being offered for sale. With these two cheap implements, anyone — and I do mean anyone — can get into your home or business in a matter of seconds.

Meet cGrid, the real-time P2P punisher

Tuesday, March 13th, 2007

A new tool has been announced in the piracy arms race. This tool can be deployed by network administrators to monitor network traffic in order to identify people using P2P services, and can automatically boot them off the network. The question is whether or not it can distinguish legitimate uses of those P2P technologies. The price: “$1 million price tag for installation and $250,000 yearly operation costs.”

Red Lambda says that cGrid monitors “a large variety of different P2P clients, in addition to other avenues of file-sharing including Windows file sharing, FTP, IM, and others,” and that cGrid does not perform content inspection but instead focuses on the behavior of the protocols being monitored. But the company does not expand on how it differentiates between legitimate uses of those technologies and illegal ones, raising questions of its effectiveness in an academic setting where students may be using P2P and other services potentially flagged by the system for legitimate, academic reasons.

I Was a Cybercrook for the FBI

Friday, February 2nd, 2007

Wired has published an intriguing series of articles on cybercrime. Definitely worth a read.

With so many fake IDs in play it was unclear to police exactly who they had in custody. Then as they read Thomas his rights, he told them: “Get me some federal agents and I’ll give you a case involving the Russians and millions of dollars.”

Thus was the beginning of Thomas’ turn to the other side. For 18 months beginning in April 2003, Thomas worked as a “paid asset” for the FBI running a website for identity and credit card thieves from a government-supplied apartment in the tony Queen Anne neighborhood of Seattle.

From bedrise to bedrest, seven days a week, he rode the boards and forums of his and other carding sites using the online nickname El Mariachi. He recorded private messages and IRC chats for the FBI as “carders” schemed to, among other things, sell stolen credit and debit card numbers, defraud the George Bush and John Kerry campaign sites, drain hundreds of thousands of dollars from bank and investment accounts, sell access to Paris Hilton’s T-Mobile account and run phishing scams against U.S. Bank and the FDIC. He did it all while battling denial-of-service attacks against his site and dodging attempts by his old partner Taylor and other carders to track his whereabouts and out him as a fed.

Just as his enemies were closing in on him in September 2004, the FBI pulled the plug on his work and cut him loose. But not before Thomas had given authorities a valuable look at the internet’s underworld, even though the strain of leading a double life nearly broke him.

The latest update of this free paint program was just released yesterday. Check it out.

Paint.NET is free image editing and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools.

It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it.

Pimp Your Router

Thursday, January 18th, 2007

I recently upgraded the firmware on my Linksys WRT54G router with the latest DD-WRT v23 SP2 firmware, and it works great. Among many other new features, I can now assign static DHCP leases, which I couldn’t do before with the stock Linksys firmware. The upshot is that now I don’t have to worry about updating my port forwarding setup whenever one of my machines’ wireless IP address changed.

If this sounds like something you’d like to try, check out the links below.

Warning: when flashing firmware, there is always a possibility of something going wrong during the process, which could potentially brick your router and render it inoperable. Make sure you understand what you are doing and the risks involved. It’s not my fault if you screw up your hardware!

It would also be a good idea to save all of the following pages locally to your computer so that you can still reference them if you lose your internet connection–particularly important if your wireless router is also your internet gateway.

Windows Tip: Control groups of windows on the task bar

Thursday, January 18th, 2007

Lifehacker has a useful tip for temporarily grouping several windows on the Windows task bar so that you can tile, minimize, close, etc., all of the selected windows as a group.

Reader Andreas wrote to tell us about a neat little trick for tiling a pair of windows in Windows.

With the first window open, press and hold Ctrl, then right-click the second window’s button in the taskbar and choose Tile Horizontally or Tile Vertically in the pop-up that appears. Presto: Two-click tiling of two windows. Right-click a third button to add a third window to the mix, and so on. (Turns out you can use this grouping method to close or cascade windows as well.) This tip also works in Vista, though the language is a bit different: “Show Windows Stacked” and “Show Windows Side by Side.” What’s your favorite tiling tip? Tell us about it in the comments. — Rick Broida

Table of Linux Equivalents

Thursday, January 18th, 2007

This is a very comprehensive list of Linux equivalents for Windows software.

One of the biggest difficulties in migrating from Windows to Linux is the lack of knowledge about comparable software. Newbies usually search for Linux analogs of Windows software, and advanced Linux-users cannot answer their questions since they often don’t know too much about Windows :). This list of Linux equivalents / replacements / analogs of Windows software is based on our own experience and on the information obtained from the visitors of this page (thanks!).
