Driver Scanning Scammers

Posted by Randy in Hardware, Internet, Operating Systems, Tips, Windows, technology on July 11, 2010

I was trying to locate a simple audio driver for a Windows XP VM I have. Basically, I'm in Linux and I want to watch Netflix but my main VM is having trouble with SilverLight for some strange reason, and rather than deal with that, I decided to use a spare VM. The movies play but I don't have sound in that VM. I realized that the VM was an N-Lite created image, which means that most of the drivers were stripped out of it. So I decided to find the driver and install it.

This is when I started getting furious. The problem is, when you search Google for driver downloads, you will undoubtedly run into nothing but scams. This is the same for Bing and Yahoo. The entire first page of just about any driver download search will have nothing but scams. By scams I mean people trying to get you to download software that costs money, just so you can download and install FREE drivers for you hardware that you've already bought.

So, looking through these scams I realized that there are at least three different pieces of software everyone is trying to sell. The first one I ran into was Driver Detective. This seemed to be the most spammed software out there. Tons of fake sites with fake "Thanks" comments on them, but no true download for your driver, blanket the first page of search results. These sites don't actually have the driver, only a download link for the DriverDetective software. Whether or not the driver detective software works isn't even the questions. The tactics used to sell this software make it nearly impossible for even a very computer-literate person to find the driver they need.

It's days like this that make me appreciate some of the OEMs like Dell, which make it very easy for customers to find drivers. Undoubtedly the adsense to the right of this post will have links to driver software, but that is expected, those are ads. They clearly say so. They are required to disclose what they are selling.

If you run into this problem, here's probably the easiest way to find the correct driver for your system. Open up device manager. This is usually accomplished through the Windows Control Panel. Once there, find the problem device, with the exclamation point beside it, and right click on it. Choose "Properties". Go to the details and look for the VEN and DEV ids. These should each be four characters long. Pull up http://pcidatabase.com on your browser. Search for those ids. You should get the manufacturer and device from that. This will at least help narrow down what driver you need. Get the drivers from the manufacturers website. Don't even bother Googling it.

How do I Block and Unblock Internet Sites?

Posted by Randy in Internet, Networking, Tips, technology on August 1, 2009

Apparently this is a question many people want asked so I'll touch on what I use to block/unblock internet sites from my home network. This method will not require one to purchase any additional software or anything. It is designed specifically to be the low cost effective solution.

First of all, your home router controls all of the traffic going to an from your home computers. Some people don't have routers. The modem, whether it be a DSL, Cable, or dialup modem, handles their routing. These instructions will work for those people as well, but anytime I mention the router, please understand that if there is no router, the modem will be doing all the work.

The router software for various models of routers are different, so it is nearly impossible to have a step-by-step howto for each of them here. Instead, it's suffice to say that most routers have a block/unblock function. Most even let you time these blocks/unblocks. So one can set up rules as to when certain sites can be viewed.

Refer to your router's manual for these instructions. It is usually rather easy.

There is a further step that can either be used in conjunction with the router blocks or by itself entirely. This method involves signing up for a free service call OpenDNS.

OpenDNS is a free service that I've used for a little over a year. It gives you a great DNS service, plus allows you to do various other interesting things like protect your home network. Basically, all one has to do is sign up for the account and change their DNS settings in the router to the IPs provided by OpenDNS. All future DNS request will go to OpenDNS.

I should probably first explain what DNS is to begin with. DNS stands for Domain Name Server/Service. When you type google.com into your web browser, your computer has no idea what google.com is. It's oblivious. First it has to query the DNS server. Usually the IP of the DNS server is provided by your ISP. In many cases, the ISP provided DNS server lags behind a bit. You computer asks the DNS server where it can find google.com. The DNS server then responds with the IP address for google.com. Your browser then knows where to fetch the information.

The DNS server configuration can be changed in your router. You will override the ISP defaults and put in the OpenDNS server IPs instead.

OpenDNS updates much faster than typical ISP DNS servers. When you buy a domain name and direct it to your hosting provider, it can take up to 72 hours for the DNS information to propagate across the internet. OpenDNS usually propagates within minutes.

Some of the protection OpenDNS offers is right up there or better than many parental block software. There are automatic settings to make it easy to block pornography or harmful sites. One can also specify sites to block. Anytime a local user tries to access a blocked website, they are told that it is restricted. This is great free service, and I hope this will help you block those unwanted websites, and if you have any questions drop a comment.

Adventures in analog video recording on Linux

Posted by Randy in Hardware, Linux Stuff, Open Source, Operating Systems, Tips, technology on July 28, 2009

Linux does many things well, but the multimedia experience can be lacking without the correct bit of hackery. I mean, some cool things can be done with Linux on the multimedia side, but typically it'll take a lot of work to learn how it's done. Mac and Windows make complex things simple, while Linux makes simple things complex.

Back when I purchased my TV tuner card for my PC, I was using Linux as my main OS. I still use it daily but not on my main PC. Only occasionally do I boot to Linux on it. I typically run Windows Server 2008 as I've talked about on previous posts. When I bought the tuner I wanted to make sure that it worked under Linux. So, I purchased one that was made specifically for Linux, a PCHDTV 5500.

It has served its purpose as a TV tuner, since I watched a year or so of cable TV in analog on it prior to the digital switch. I have never been able to get the HD side of things to work on it. Either it's beyond me or my cable company just had all of the channels encrypted. I didn't spend enough time on it to find out.

Recording analog video in Linux can be FUN. By "fun" I mean the type of fun one has pulling their own toe hairs. Be forewarned, getting a good recording is best done from the command line. I tried many ways. I ended up going with mencoder.

That being said, there's not much you can't do with mencoder and ffmpeg from the command line.

I have some VHS recordings I'm converting to AVI and then later on to DVD. I first had to purchase a VCR because, wouldn't you know it, I didn't have one that worked.

After that I had to come up with a good way to connect it to my capture card. The card has coax and component inputs. The new VCR didn't come with any coaxial connections. The capture card had a yellow RCA connection for video. I could use that but then there was the problem with audio. The capture card had a 1/8" jack for audio. Luckily I had an RCA-to-1/8" adapter for one of my gadgets (not sure which). I ended up using two sets of RCA's.

I was amazed I actually got audio and video from it. Here's where more fun came in. I was running virtualbox in the background. Everything I tried to use to record the video told me that /dev/dsp could not be opened. I went through many hoops trying to troubleshoot that issue. I should have realized it sooner but it was all virtualbox's fault. Next time I'll make sure it's not running when I'm dealing with audio.

After all of those problems were worked out, I was able to use:

mencoder tv:///1 -tv driver=v4l2:width=640:height=480:forceaudio:adevice=/dev/dsp -ovc xvid -xvidencopts bitrate=-750:threads=2 -oac mp3lame -lameopts cbr:br=64:mode=3 -o /home/five/homevid.avi

I'll try to explain some of what is going on in that command. Mencoder is the program itself. There's little to be said there. The next part is interesting: tv:///1  That tells mencoder we are using the tv card and that we want to use the composite1 input. Typically it defaults to input=0 or tv:///0, which is the coax TV input. There are three inputs on the card: tv, composite, and s-video. The next part (driver=v4l2) tells mencoder that we want to use Video4Linux2. Then we specify the width and height of the capture. The forceaudio bit was placed there during my troubleshooting. It just forces the use of audio device /dev/dsp. I had tried a couple other devices during my troubleshooting, thus the addition of that option. Then we have the option for output video codec (xvid). I set the bitrate and the number of threads. I actually upped that bitrate considerably later to around 2048. I believe I'll end up upping it even more for the next vid. I did the same with the audio output bitrate. I set it up to 256.

That should help anyone experiencing some of the pain I went through.

Slow wifi on iPhone 3GS

Posted by Randy in Apple, Internet, Networking, Tips, technology on July 24, 2009

I bought a new iPhone 3G S yesterday. These things are very nice, and I'm not an Apple fan boy by any stretch. One thing that was bugging me, however, was the slow speed I was getting from the wifi. I was getting faster speeds from the 3G network than my home wireless, and this is while I was sitting right next to the router, so it wasn't a signal problem.

I found the solution to this after reading through many, many forum posts. I saw others were having the same problem as me and were getting responses from people like "reboot the router" or "reset your network settings on the iPhone." This is all well and good and I'm sure those people meant well but there was a big problem with their responses.

First of all, everyone having this trouble said that the wireless worked fine on their computers but not on the iPhone. Secondly, there aren't many settings to "reset" inside the iPhone's network settings. There's just not anything in there that would cause this type of issue.

The solution to the problem ended up being an advanced setting on the router itself. From what I can tell of the issue and it's solution, the iPhone's wifi is just a bit more picky than a standard PC wifi device. Here are the settings I eventually had to change on my Netgear router.iphonewifisettings

The important items here are the fragmentation threshold and the CTS/RTS threshold. Each of these were set to their max value previously. After changing these two settings, my iPhone started working like a champ.

If you are experiencing the same problems with your iPhone or iPod Touch's wifi, change these settings on your router. Also note, these settings have slightly different names on some routers. Refer to your router's manual for more info.

Edit: I've gone much lower with these number with much success for my less powerful mobile devices. Going too low does seem to cause issues with more powerful computers on the wireless network. Test this out with lower settings and post your success or failures in the comments.

Right-click stopped working in Word

Posted by Randy in Applications, Tips on June 11, 2009

I had this problem with Word 2007 today recently. I thought it would be helpful to post the fix that worked for me. I'm not exactly sure what caused the problem. From what I've read it can be caused by some add-ins. The results of this issue are 1.) no access to Word options(they will be greyed out) and 2.) mouse clicks inside of a document will not work. This limits your ability to use Word completely. It was a rather frustrating fix. I first tried repairing my Office 2007 installation. This didn't fix the problem and actually the repair crashed. I should point out that this is on Windows Server 2008, but others have had this issue in Vista.

After the repair crashed, I tried reinstalling Office. This crashed a few times and I realized I needed to run it as an administrator. Running it as an admin allowed me to uninstall Office but after reinstalling it, I got the same results as before. This led me to believe that maybe there was a permissions issue with the executable. I tried running WinWord.exe as an admin. This didn't help either. So I decided it must be a profile issue. I went through my profile (local and roaming) trying to find all mentions of Office and Word. I deleted those and still had the issue. Sometimes this will fix issues, but in this case it didn't.

After some research I found that the problem could be cured by deleting some registry keys.

Just open regedit. Browse to HKEY_CURRENT_USER\Software\Microsoft\Office\Word

The version number should be 12.0 but I believe 11.0 could be effected by this issue as well. At any rate, select Data. Then, choose File -> Export. Create a backup of the branch. You can name it whatever you want. After you have saved the backup, delete "Data". Close regedit and start Word.

The problem should be alleviated.

Make Twitter Better

Posted by Randy in Applications, Tips, Web Development on May 26, 2009

One of the things I like about Twitter, believe it or not, is the simplistic design. There's not a lot of useless options. There not many things to click on at all really, compared to other sites. There are a few missing items that should be on the site, however. I just recently installed a Firefox extension that accomplishes everything I need.

I've found that a lot of the twitter "clients" are lacking. For instance, I can't easily search and follow people from TweetDeck. I really like to just use the web client. I only thing that I could use on the web interface is a notification of @ replies. Every other option that I found useful in the clients is now available on the web client via Power Twitter Firefox extension. There's also a few features I wasn't expecting. For instance, Song.ly is now integrated. I had never tried Song.ly until I installed this extension. I love it.

Check out the extension. It's worth it if you Tweet much at all.

Just How Relevant is Google

Posted by Randy in Internet, SEO, Tips, Web Development on May 1, 2009

We have all come to expect good things from Google. In fact, many of us have come to believe that Google is the best at everything they do. This is especially true with their original application, their search. For the past few years Google has ruled the search market. It got there by making the most relevant search results appear every time a user executed a search.

Those days may be over. Recently, I've noticed a trend that Google isn't giving very relevant content. I don't think I'm alone, and I have a pretty good idea why we are getting such bad results. It's not entirely Google's fault. There are many "white hat" and "black hat" search engine optimizations that are being used to manipulate the results. Marketers are trying to draw content to their sites. That's how they make money after all. SEO has been used ever since the first search engine. Google just seems to be lagging behind in making their algorithms detect unwanted SEO.

This isn't to say that those marketers are doing something wrong exactly. It's just that most of them are concentrating on Google. Google is, after all, the most popular search engine. They know what works to get ranked on Google, so they do it. They do a lot of it. This skews Google's search results, but doesn't necessarily effect Yahoo search results because Yahoo uses different algorithms to determine where a result ranks.

Google also is notorious for de-indexing RELEVANT sites by mistake. For instance, this site seems to have been de-indexed, and I've not been attempting to SEO this site much at all. It could be due to my use of a WordPress plugin called All-in-one SEO pack, though that really shouldn't have anything to do with it either.

Here is my single example that has been perplexing me for a month or so:
Once upon a time, there was a script for the XChat IRC client, called "XLack". This script is my favorite system information script for XChat. I've used it for probably 4 or 5 years. The home site for the script used to be xlack.tk. This was where everyone would go to download it. That site is now a parked domain. It has been that way for close to a year. If you search google for "Xlack", xlack.tk is still the number one site. It is no longer relevant at all. It's a parked domain. In fact, if one tries to find a site from which to download the xlack script, one finds that there are none listed on Google.com.

Now take that same search over to yahoo.com. A simple search for "xlack download" gives you this site, which has the relevant download link of the actual script. Yahoo.com provides more relevant results. Try it on any of your search and see if you don't get better results from Yahoo or even Live.com. I guarantee you'll have more success from them these days than you do Google.

CHM file not working

Posted by Randy in Applications, Operating Systems, Tips, Windows on April 2, 2009

I have quite a few ebooks in various formats, mostly PDF and CHM. Some time ago I noticed that an update from Microsoft limited the ability to open CHM files. I had previously researched how to fix this but after a recent reinstall of Windows I've found myself with the same issue as before. I had forgotten how to fix it. I also noticed that the fix isn't very easy to find. So, I thought I'd post it here for anyone who may run into the same issue.

Here is what the error will look like:

image51

You will see an error like "Navigation to the webpage was canceled."

This was actually a security feature Microsoft added. Intranet and internet downloaded CHM files are blocked by default. There are a few ways to fix this, we'll start with the least preferred.

This registry hack will enable CHM files to open remotely or locally. This is quick and painless but could lead to security risks, though I've never heard of anyone getting hacked or acquiring a virus from a CHM file. At any rate, use that registry hack at your own risk. To install it, simply download the .reg file, right-click it, and choose install.

The next way is probably the easiest but it requires that all CHM files be downloaded to the local machine. This, to me, is not a problem. This will unblock all local CHM files and it's an obvious fix that just elluded me for some reason. When the CHM file is clicked a dialog box appears with a checkbox that says "Always ask before opening this file type". According to Microsoft, unchecking this box will unblock all the CHM files that are on the local machine. I've not tried this method, however.

The final method was the one I used. It is simply to unblock the files individually. I was unaware that there was and "unblock" button inside the properties menu for the file. Simply right-click the file, choose properties, and in the "General" tab there should be an Unblock button at the bottom. Simply click this button and the CHM file should open and display correctly.
