I’ve officially “released” this song and don’t have much planned in the way of making changes to it. If I did, I’ll release it under a new title. Using the player below, you can download the high quality WAV file of this song for free. Enjoy!

Okay, probably not the first in my life time, but since I can’t remember any other in my past I’m gonna just say this is the first. Probably last too.

I have encountered a good variety of computer problems this year, many of them classic textbook cases. Dead DVD burners that needed to be replaced; computers running slowly because they really needed a RAM upgrade; hard drives needing to be replaced with larger ones; networks with printers needing to be setup so multiple computers can send jobs to it…. these are the kinds of problems that we were taught how to resolve in school, primarily because they were easy to recreate/simulate for lab assignments. I remember the fun we had when students were split into pairs and told to “test” each other by breaking a system and not telling the other person HOW they broke it, as a challenge to see if they catch all the hidden problems. Wanna make a computer run slow? Pull a stick of RAM out of it, slightly. Wanna make a network printer stop working? Change its IP address. Wanna stump someone with no video on the monitor? Just turn the contrast/brightness all the way down to see if they can figure it out. The goal was to reinforce the premises that you should never, ever dismiss the lowest common denominator when trying to think of different diagnostics and best case solutions for a problem. Even something as simple as “is it plugged in?” should never be assumed to have been checked until you’ve done it yourself. In networking, you would say “start with the physical layer, and work your way up to the higher levels until you actually reach the application.”
These problems don’t strike me as novel or very interesting, mostly because you expect to see them occur at SOME point in time and at random. Electronics wear out, lightning can strike at any moment, dust buildup shorts something out or jams a cooling fan; these things just happen from time to time. But there was one issue I saw this year that really stood out as occurring more frequently than any other problem by far. A problem that seemed to happen so suddenly, so widely that you could almost call it “trend setting”. So I wanted to take a look back and talk a bit about a problem I’ve seen more often than anything else this year:
The most prominent problem I saw this year, more than any other problem I got calls about, were from people saying they had gotten alerts popping up on their system similar to the one pictured above. Typically you would be intimidated by a popup that said your system had a LOT of viruses on it and to click on various buttons/links to remove them. Unfortunately it was all a ruse as these alerts were themselves part of a virus masquerading around as anti-virus software, taking computers hostage. Their names and appearance had some variation but most of their tactics were the same:
I began to get a lot of phone calls for this exact type of issue during the middle of the summer this year, and of course everyone wanted to know how their computer came to get this sort of junk software on their machine in the first place. Along those lines: Where do viruses come from, how could one have gotten on my computer and WHY on earth would someone create such an evil thing in the first place?
I don’t have the monetary resources to conduct an “official” study (and as such you should classify everything here to be anecdotal), so the next best thing I can do is look for things that were in common between PCs that fell victim to the same infection at about the same time. The one thing that stood out the most to me was that Adobe Flash, Adobe Acrobat and/or Java were out of date and needed updates to be installed.
In the year 2010, Adobe has had to make multiple announcements about zero-day exploits found in their Flash plugin that could allow Flash to do things like crash a computer or to take control of it (e.g., facilitate the installation of a malicious payload or virus).
Just what is Flash, anyway? Flash is a plugin for web browsers that has been a mainstay in webpages for over a decade. Youtube videos, for example, are played within Flash. Most advertisements you see on the web use Flash to animate video, elements, buttons, letters, etc. Some websites are made entirely in Flash. In the early days Flash was designed as an alternative to animated gif images and cartoon-like animations because for some uses it could actually conserve bandwidth because instead of pixels and color pallets taking up file space, you would instead be working with vectors (think connect-the-dots to create a shape of something, like a stick-figure man, and move the dots/vertices to animate it). An awesome example of cartoon flash animation using very little bandwidth is www.homestarrunner.com (a favorite cartoon series I used to follow in the old days). Over time Flash has evolved into quite a feature rich plugin that many have attempted to clone and dethrone, but all attempts have failed (so far).
In any case, as a result of being more efficient than animated bitmaps and saving web hosts money on bandwidth and faster loading times while increasing the “eye-candy factor” during the days of dial-up, Flash became a preferred/common means of deploying advertisements on the web, and eventually advertising itself became so big that there are now companies that do nothing but produce and host Flash-based advertisements for other websites. What this means is that many websites do not actually host/serve the advertisements that you see on their website, as they have offset the bandwidth requirements for this function to third party companies. Unfortunately, because advertising is a big deal online, it raises the bounty and incentive a malicious hacker might have to penetrate the advertising servers and replace clean advertisements with infected versions that would download and install Malware all by itself, taking advantage of security exploits in the plugin that have not been patched by the user. This has been going on for at least the last 4 years or more and it’s a phenomenon knows as “Malvertising”.
So what are some ways to prevent this type of thing from affecting you?
If you see an alert like the one pictured above, address it immediately. Far too often I see users just minimize the window or click “Later” and forget about it for the rest of the session. The same thing goes for Windows updates, Adobe updates and generally speaking any updates for software that you use on a regular basis. Updates happen because security vulnerabilities are found and patched, or slight tweaks resulted in an increase of the programs performance, or because they are adding a new cool feature. Whatever the case may be, software updates are your friend and you should welcome them without hesitation. If you are asked to update a piece of software you have never heard of before, just type the name of that software into Google. With just 30 seconds of reading you should be able to determine if the program that has an update pending is legit or malicious.
The two most common anti-virus programs I’ve encountered on computers THAT WERE ALREADY INFECTED has either been Norton or McAfee; both have never seemed to live up to their hype or justify the sponsorship of PC manufactures and Internet Service Providers. Norton in particular spends gobs of money on absurd advertisements about how you should protect your oscillating fan from David Hasselhoff or saving your unicorn from Dolf Lundgren. The use of silly metaphors in them are meant to parody the fact that most people don’t understand viruses anymore than they understand Dolf scorching My Little Pony with a flame thrower, purely for illustrative purposes of course. Lets dumb it down so much that people will say, “This is so dumb, it’s smart (advertising).” Now we know why a copy of their software costs around $60 or $70 per year…
The sad truth about anti-virus software is that NONE OF THEM are perfect or necessarily worth their weight in dollars, simply because virus programmers have the upper hand. If a hacker discovers a vulnerability that no one else has discovered yet, he may just keep it in his “stash” for use later. OR, he might sell that knowledge to the Russian mafia or any number of other interested parties who have their own stash and secret agendas. It is suspected the Stuxnet worm that ran rampant through Iran earlier this year was the product of a government agency, due to the sheer amount of zero-day exploits it contained for propagating itself, along with its overall sophistication and extremely specific targeting.
Was it a coincidence that days after Adobe announced the discovery of a zero-day exploit in their Flash and Acrobat Reader software in early June that a lot of people started to call me for the exact same Malware problem? It’s quite likely the vandalism on advertising servers was timed to correspond with these vulnerabilities to maximize exposure. It takes Adobe around 2 weeks to release patches for vulnerabilities like this so there is a window of time users are exposed and at risk, and this window of time extends out further if you avoid applying updates.
Despite this sad and depressing fact, you’ll be happy to know that many anti-virus programs do provide generous protections that you cannot otherwise get without them. There are two programs I recommend everyone check out:
Microsoft Security Essentials is produced by Microsoft itself and is a free program you can install on your system. It will actively monitor your computers activity and help prevent virus infection. I encounter network security professionals in web forums here and there and most of them have really begun to sing praise for this program, because of it’s small footprint and high level of virus detection and removal. Malwarebytes is another program that comes in a free form (though there is a paid version that automates all of it’s functions so you don’t have to do manual scans and updates with it). Malwarebytes has been an absolute life saver for me this year as it was able to effectively cure about 8 out of 10 PCs of all their woes with one scan.
There are many other commercial (pay) anti-virus programs out there that are good, such as AVG, Avira Anti-Virus, Avast, etc., but I don’t have the time or resources to review all that are available. While you might be able to find other websites out there that post “comprehensive reviews” of this type of software, it should not surprise you that sometimes these articles are just advertisements for commercial anti-virus software dressed up to look legit and non-partisan. In my opinion, the best reviews for these things come from individual users and a great place to find reviews for antivirus software is Amazon.com. They sell some anti-virus software and each of them have their own collection of user reviews that are worth reading over if you decide you want spend money on extra protection not offered by free solutions.
If your computer is directly connected to the Internet (and does not pass through a router of any kind) then you are putting your computer on the front line and you should protect it with some armor if you want to stand a chance in the wild jungle that is the Internet. Firewalls prevent unwanted network traffic from passing between your computer and the Internet. In the same way Flash has it’s own flaws and vulnerabilities from time to time, so too does Windows itself and many vulnerabilities can be exploited with nothing more than a network connection. Having a firewall in place helps eliminate this possibility. A firewall can also prevent rogue software that is already on your system from “phoning home, contacting the mother ship” to update itself or otherwise expose your personal data to would be data thieves.. It’s not anti-virus software, but it does add a critical layer of protection. Windows itself comes with a firewall built in but it’s not as feature rich as some third-party applications out there. The most popular free firewall that I know of Zone Alarm Free.
One of the great features of Zone Alarm Free is the ability to let it block advertisements for you, although its not very smart about it as it basically blocks all gifs or flash content embedded in a website. This can break a lot of websites that have legit uses for Flash, like Youtube. So you may want to look into a more proper ad-blocking plugin/add-on/extension for your browser. A great one for Firefox is called Adblock Plus.
Recently I stumbled across a funny description of Internet Explorer: “It’s a great tool for downloading Firefox or Google Chrome.” And it’s the truth. Internet Explorer has struggled to achieve a respectable reputation among security experts as being a secure browser, when compared to others that compete against it. Among them are:
These are all very capable browsers that have a great reputation for handling security and also have shown impressive turnaround when vulnerabilities are discovered. I would highly recommend you download and install one of the above browsers and start to use it instead of Internet Explorer.
The above image is an exaggeration of a point I would like to drill home: Toolbars are 99% junk and often facilitate no additional functionality than a web browser already has built into itself. Pop-up blocking and search bars are standard in all modern web browsers, for example. Many times I have seen toolbars for “MyWebSearch” on computers that happened to be infected with a virus. I can’t necessarily say there is a causal connection between that particular toolbar and an increase in exposure to malicious software, but its fair to suspect it because if you search for “mywebsearch” on google, every single link (except the first one) goes to instructions for how to remove it. It’s clear that NOBODY wants this toolbar, and the same could easily be said for most toolbars. Get rid of them, please!
The easiest way to remove most of these is to use the Add/Remove Software applet in your control panel (In Windows Vista/7, it’s called “Programs and Features”). If this fails to work then you can often find instructions for manual removal by searching for them with Google.
Limewire is dead, but the way it worked will live on in other programs like it. The way Limewire worked mostly relied on you connecting to other peers like yourself and the mesh collective would commence to pass files back and forth in a decentralized fashion. The problem for Limewire is that it wasn’t entirely decentralized, which is why they were able to shut it down like they did Napster several years ago. But still, the primary way it worked was by letting anybody share pretty much ANYTHING they wanted, without any real fear if they did something like disguise a virus as a popular new song by some teen-pop musician and share it out to the world as a “joke.” Using software like this is your call and any legal considerations involved weighs entirely on you. If you do decide to use file sharing software of this nature, make sure you police all your downloads to be sure you haven’t downloaded a Trojan horse.
Not everybody reading this (in fact, few people reading this) would be willing to walk forward and admit to visiting porn websites online, but such websites make up a large chunk of the web and due to the rogue nature of some of them you are more likely to find ads, script code laced with viruses or strait up automatic downloads for executable binaries with names like “Video.exe” that can lead to your computer being infected. It’s quite plausible that you might even visit one of these sites “TOTALLY BY ACCIDENT!!!” So one thing you might consider using is a parental control blocking application that filters out web addresses and reduces the chance of you visiting one by accident or otherwise. A robust, free parental control program worth trying is K9 Web Protection.
It would be hard for me to write all of the above out without making a passing mention of using a different operating system, at least part of the time. I realize not many users are interested in making a big switch from one OS to another, but it is very easy to at least get your feet wet with a Live CD. In the case of Ubuntu Linux you can boot the entire OS from a CD without making any changes to your computer. It’s like playing a demo for a video game before deciding to install the full copy, for free. Instructions for downloading, burning and booting are right on Ubuntu’s website so if you’re even SLIGHTLY tech savvy you may find you enjoy working in Ubuntu more than you do Windows and feel relief from not having to worry about viruses or malware infecting your system.
As I mentioned before, this Malvertising problem is not new but the spike in its frequency of occurrence this year was interesting to me. It wouldn’t be far out to predict another wave of infections like this striking again, but with the above advice and your increased awareness of the possibility of being infected in such a way should help to drastically reduce the chances of you falling victim to something like this.

Kinect is a new accessory for Microsoft’s Xbox gaming console, which involves a special infrared light emitter and a pair of cameras that can see you in 3D and use the movements of your body (arms, hands, feet, everything) to control the game, instead of actual game controllers with buttons. There’s been a lot of mixed feelings about how good of a product it actually is and considering it’s a first-generation product of Microsoft there’s probably good reason to be very cautious and skeptical. I own a PlayStation, a Wii and have avoided getting an Xbox over the years for multiple reasons, the largest concern being the quality of the hardware (red ring of death, anybody?). I’ve yet to see a video demonstrating Kinect that actually causes to want to buy one; call me old fashioned?
Today I came across a video that someone made with a separate video camera to record themselves while they played a game called GEL Ride; a kids racing game like Mario Kart. He did this so you could see how the Kinect reacts to body movement. All I can say is… this is NOT the game that will convince me to get a Kinect and Xbox. See for yourself… and yes, this video is real and it is hilarious.
On the non-gaming side of things you might be interested to learn that the protocol used by the Kinect to communicate with the Xbox has been hacked, and people have been using their Kinects to do things no one anticipated. It’s suspected Microsoft intentionally left the protocol open to being so easily reverse engineered and the suspected motive of leaving the protocol wide open might be that it’s just one more way to sell Kinects to non-Xbox users like me. Hell of a Plan B if you ask me; Kudos to them. Here’s one of the COOLEST things I’ve seen anybody do with it so far (it gets really cool about 30 seconds in):

I’ve recorded a new screencast introducing Ubuntu 10.10. This video gives beginner Ubuntu users a brief tour of the operating system, and covers installing updates, proprietary drivers, customizing appearance, and installing software via the Ubuntu Software Center as well as with downloaded *.deb files, all in less than 10 minutes.

Preamble: The techniques described in this guide are intended for educational purposes and should not be used to bypass copyright restrictions or download copyrighted material without consent from the respective owners/licensees. In the below example I use a track by Nine Inch Nails for this demonstration for two reasons:
1. I already own this album (in fact I own every Nine Inch Nails album; I’m what you would call a “loyal fan“).
2. The album was published under the Creative Commons Attribution Non-Commercial Share Alike license. This means I could give you a copy of the song because I purchased it. Look out for musicians who publish their works under licenses like this.
So let’s get to using this Youtube Downloader thingy!
First, download the software from Download.com by clicking here.
Run/Open the file once you have downloaded it to install the software. Once installed, you’ll have a new shortcut in your Start Menu. This is what the program looks like when it’s running:
Leave this window up and go visit Youtube. Find a video you like and then copy the URL from the address bar at the top…..
…into the first box in Youtube Downloader, like this:
Now click Download.
Once the video is downloaded you can convert it to an MP3 by changing the selector at the top from “Download a video…” to “Convert or play a video…”, like this:
Now all you have to do is click the Browse button to search for the file you just downloaded, and change the “Convert Video to:” box to read MP3, like this:
Now click Convert. It will ask you about quality settings (and of course it’s best to just leave it on “Best Quality” and click okay). That’s pretty much it. A conversion process will happen, taking perhaps 30 seconds, and you’ll be given an MP3 file that you can play on pretty much any portable audio player out there. It’s up to you if you want to delete the original video file.
Piracy/file-sharing can be a very polarizing topic to talk about, especially when the conversation occurs between professional musicians who make their living off writing music. On one side of the fence you’ve got your Lars Ulrich and Gene Simmons who see piracy of their music as a direct threat to music sales and thus their paycheck. On the other side of the fence you have bands like Radiohead and musicians like Trent Reznor who see the sharing of their music as a marketing platform that can increase band exposure, increase their fan base, and subsequently increase their physical merchandise and ticket sales. Both sides are entitled to their opinions but I lean towards the latter group when thinking about this stuff.
Along the lines of music piracy is software piracy. There is a software developer who goes by the name Notch who created a computer game called Minecraft by himself that has earned him nearly one million dollars in under a year, and it was still in the Alpha stage when it hit that impressive number. He has a very keen insight into piracy and I would like to suggest you check out his blog post about the topic if you have the time. It mostly boils down to distinguishing (or debating) the difference between the loss of potential revenue versus actual revenue lost, determining a fair way to measure the differences.
In marketing there is a strategy known as “loss-leader” and pirated music could be thought of as a loss-leader for a musician who has additional products to offer, like vinyl, or limited “deluxe edition” packages, not to mention concert tickets and who knows what else (one of my favorite musicians offers up everything from autographed cover art by Strom Thorgenson to 5 hour long studio workshops with the band and their very own equipment). Then there’s new, up-and-coming musicians who don’t yet have anything better to hope for than a chance to be listened to and are willing to let people preview their entire collection in the hopes of turning them into a loyal fan who will go buy all their albums and other merchandise someday down the road.

A few days ago I was emailed by someone who had a few questions about upgrading an old laptop they’ve had for several years. They were very certain that they needed a larger hard drive but had heard of “RAM” (Random Access Memory) and didn’t know if it was something different or the same as a “hard drive”. This is a common mistake many make. To help remedy mistakes like this I like to create simple analogies to help explain how a computer works so they are easier to understand. In this particular case I like to use the human body for comparison.
So let’s imagine that instead of a computer we were talking about the human body. The parts between the human body and computers that would roughly equal each other would be:
CPU = The math-crunching part of your brain.
RAM = Your short term memory. Stuff in here is being thought about right now and is instantly available to the CPU if needed.
Hard Drive = Not so much a part of your brain as it is a thick book being held in your hand. Like a book, it requires you to actually LOOK at it to get information out of it, which requires you to also use your other hand to thumb through its thousands of pages and use a pencil and eraser to add or remove information from it; lots of physical hand movement going on here. It is similar to your own long-term memory. Information stays here after you shut the computer off or go to sleep, but takes longer to recall and longer to write into than RAM.
For reference, here is a short video showing off the inside of a hard drive while it is working. Think about the book and your hands thumbing through and writing/erasing pages while watching this video:
In computers, RAM consists of little chips that do not contain any moving parts but can store information temporarily while the computer is powered on. Data can be read from and written into RAM in a matter of nanoseconds at rates as fast as or faster than a gigabyte per second, primarily because there are no moving parts, just like the CPU (or the human brain). In a very real way, RAM and the CPU are like different parts of a brain that work in concert to produce results quickly.
When a computer is told to load a program, it has to copy that program it into RAM for later use. In the human body, “loading a program” would be kind of like opening that thick book I mentioned earlier to a chapter like, oh I don’t know, “Chess: Instructions and Rules.” If you can remember all the instructions and rules right after reading them for the first time, then you can play the game without any need to stop and read the manual every time it’s your turn. Likewise, if a computer is able to load a program into RAM completely, then it won’t have much need to access the hard drive after it’s been loaded.
In the old days, if you didn’t have enough RAM to load your software into, it simply wouldn’t run at all. This isn’t true these days because modern operating systems use a feature called “Virtual Memory” (or “swap space”) where free space on the hard drive is used as a sort of simulated fake RAM. This would be kind of like taking that book, turning it to the back where the pages are blank, and taking notes… a LOT of notes. This leads to the dreaded hard drive “grind” (that sound you hear when the hard drives is constantly doing something; that KRRRRRRRR sound) where the hard drive is so overwhelmed with reading and writing information that the entire system slows to a crawl while it waits for the hard drive to finish whatever it’s doing. In humans, this would be kind of like trying to do taxes for 20 corporations at the same time; you’d practically wish you were dead.
Fortunately, RAM can be easily upgraded and these days it’s one of the most economic ways to improve your computers performance and postpone its obsolescence. With more RAM, your computer can load larger, more complex programs and relieve your hard drive from the daunting task of pretending to be RAM.

Some of you might know me to be a bit of a Linux geek who is a sucker for the open-source philosophy and culture. It sure is a beautiful thing in the world of computers; using software that’s free of charge and free to modify because a bunch of people decided to give it away to the public and do whatever they want with it. This has worked out VERY well for Linux since it began, with bored programmers using the Internet as a global workbench to approach and tinker with any software they wanted and the best results would come to the surface as a new standard, often with no money changing hands.
It’s difficult for most people to imagine doing something like this because we don’t know a thing about computer source code. We sort of have a foggy idea about it and could boil it down to “a list of instructions for a computer to follow” and add that those instructions can be edited and improved upon by anyone. Any description more complex than that and it starts to sound like Greek… but for this post, it’s good enough.
Now imagine you took this model of open-participation and applied it to music production, doing it all on the Internet. You’re a musician, you play an instrument or have a singing talent and want to find other musicians who share your musical taste. This is difficult to do in the real world, especially if you’re stuck in Kansas like me. Sure, it’s easy to find a Kareoke machine on any given night if you look hard enough but finding good, original, local musicians is hard. So the next best thing is to go online and (in a way that’s reminiscent of posting personal ads looking for a significant other) post your own creations/recordings to be judged by others… perhaps even loved by others, modified by others, built upon by others until eventually the little tune or melody you started with turns into a fleshed out composition that sounds very professional.
This is exactly the kind of situation I’ve found myself in during the last 3 weeks after I did some searching on google for “online music collaboration” and discovered Kompoz.com and indabamusic.com.
I signed up for both at the same time and uploaded the same music (three songs of my own) to both sites. All I had to do after that was sit back and wait for others to possibly like my music and wish to add something to it, or not. Over on Kompoz, in a matter of just 2 or 3 hours, a fellow from Latvia named Nikitt had uploaded a new guitar track to one of my songs on Kompoz. Within a few days after that I was getting emails from people wanting to perform lyrics to the track. A few days later, another astonishing guitar track was added by a dude from Florida who calls himself Grumpy. And in all this time, none of the tracks I uploaded to Indaba got even a hint of attention or interest from anybody. So either they think my music sucks over at that website or (more likely) the user interface for indaba is a mess that makes it difficult for bored musicians to find new projects. So maybe Indaba would work for you but it certainly didn’t work for me.
But enough about Indaba failing me. Kompoz on the other hand has really bolstered my dream of writing a lot of good music. It’s just so much easier to be able to upload something and for someone else to come along and add an idea to it. It really is a lot of fun; I would tell my fiance Kristin that it’s like Christmas every day because you never know what you’re going to get. This happens in part because some of the people who use the site live on the other side of the planet and leave stuff online while you’re asleep and when you wake up you might be surprised to find new recordings uploaded or at least some productive comments.
So this is what I’ve been doing with some of my spare time lately and just wanted to share. You can check out my Kompoz profile and projects by clicking here. If you happen to be a musician I encourage you to join Kompoz.com with a free membership, but if you’re serious about music production it pays to get a premium membership for $50 a year so you can exchange high quality WAV files and even publish music for commercial release and get royalties out of it.

So about 90 seconds ago I learned about this website and knew I had to write a quick blog about it. The site is called Ninite Easy PC Setup. This is a website that allows you to download multiple popular Windows applications, from web browsers to anti-virus software, and install them all at once!! This is a HUGE, HUGE time saver.
You look through their selection of software, check off the programs you want and it will create a custom bundle from your selection and wrap it all into one easy install package for you to download. When you run the installer, it installs all the apps, one by one, automatically without user intervention and without any spam “extras” that might come along with some of them (like browser toolbars that do more harm than good).
Check it out at www.ninite.com
