I've recently become a die-hard git convert. I used to use subversion but branches in subversion and always having to be connected gave way to an interest in git. Branches in git are ridiculously easy and I like the fact that I don't have to be connected to save changes. Then I started using git and discovered rebase.
My typical workflow is to work and commit locally and then push up my changes when I have major chunks of work done. I also like to try and keep groups of commits small and related.
Typically though I'll do lots of commits and rebase lets me group related commits. You typically don't want to do rewrite the history (what rebase lets you do) to commits you've already pushed to the server but if you are the only one working on it or are sure it won't screw anyone up, you can --force a push to get your newly rewritten history up.
Now, how do I use it? If I have local changes I'm not ready to commit yet, I first use the 'git stash' command. This creates a temporary branch and stores your changes there. You could create another branch if you want and then switch back to rewrite history, but I find the stash command handy.
Now we do the rebase, in this example, we'll go back 5 commits. 'git rebase --interactive HEAD~5' Of course change 5 to whatever number you want to go back. (A quick git log should give you a good idea of how far to go back.)
From here, you'll get a list of commits, each with the work 'pick', the commit's short sha and the commit message. What I primarily use is pick and squash. Just move the line you want to merge into something else under the commit you want to merge into. Change pick to squash. Now save.
It will then open up your editor and ask you for a new commit message. It will show you both and let you change it. Saving this will rewrite your history. Now you can push up your newly rewritten history. Now to get back the changes you stashed away, simply type: 'git stash apply'
Git is really fast at what it does, even when pushing changes to the server. The only time I've noticed it taking a while was transferring an entire bare repository over a slow ssh connection. (Not really gits fault) Once I get very comfortable with it, I'll create a workflow chart that documents how I use it in hopes that it helps others.

Bias in the media
It really bothers me to see blatant bias and ignorance in the news. I just read this short article from reuters:
First the criminal was "violating parole on charges of assault with a deadly weapon." I don't care what state you are from, it's illegal for him to posses a gun. He shot at two police officers, do you still think at this point he cares about breaking yet another law? Do you really think he got his gun legally?
But let's not forget that he opened fire with a rifle at the Special Weapons and Tactics team. I abhor the term assault rifle because really, if you are shooting at someone, any rifle is an assault rifle. The assault weapons ban was based on meaningless components and really seemed to focus on appearance rather than some sort of increased capacity for violence. And while we're on the subject of words and phrases, let's also look at "assault with a deadly weapon." Ummm... aren't all weapons deadly? I mean I think that's part of the definition of weapon. But it sounds so much more horrific than just assault with a weapon.
So how are more gun laws going to affect people like this man from getting guns? There not, just look at prohibition and the war on drugs. People still get drugs despite them being completely illegal. If something has value to someone, they will find a way to get it. In the case of guns, I really think the best defense is to arm as many "good guys" as possible. Then maybe the bad guys will think twice before using a gun for evil.
Ok, now some may read this and think the best thing to do would be more gun control. While it's not stated, there are many phrases that clue you into this. "Gun battle," "opened fire," "assault with a deadly weapon," "assault rifle." Now if after reading this you think there should be tighter gun laws, let's think again.OAKLAND, California (Reuters) - An Oakland, California man killed three police officers and wounded two others on Saturday in two separate shootings that began with a traffic stop and ended with a gun battle, police said.
Lovelle Mixon, 26, was pulled over during a traffic stop in the early afternoon. Mixon, who was wanted for violating parole on a charge of assault with a deadly weapon, opened fire on two officers, one of whom later died, and fled.
Officers found the suspect later that afternoon in an apartment.
When a Special Weapons and Tactics team forced their way in, he opened fire with an assault rifle, hitting three officers, including two who died from the wounds, according to a statement by police in the San Francisco Bay area city.
Mixon was killed in the gun fight, and the officer wounded in the traffic stop is in critical condition.

Current economic situation
Things have been busy for me lately which is why there has been an absence of posts. I just want to talk for a minute about our current economic situation. There's a lot of talk about why we are in the mess we are in and what to do about it. Being the geeky type, I like to try and use the scientific method to solve problems rather than just go for a feel good measure. So first we must form a question.
I feel the question should be twofold, first what got us into this mess in the first place because as we all know, "those who cannot remember the past, are condemned to repeat it." Plus if we know what causes the problem, we should be able to prevent it from happening again right?
The second question I'm sure you are thinking is how should we fix it? I feel that is too vague, fix what? Let's first define the problem and then we can try to figure out how to fix it.
The way I see the current problem is that unemployment it up, value of the dollar is down and people aren't spending as much money as they used to giving us a low Gross Domestic Product (GDP). So what caused this?
It's hard to say exactly what caused this as there are a lot of variables to consider but I think there are a few things that stand out. Unemployment is tricky so we'll come back to it after we consider the second point, the value of the dollar.
This is an easy one, why is the value of the dollar so low? Because the government keeps printing money. What you say, the government can't just create money out of thin air? Sure they can, what they do is they set a target interest rate. To make the market converge to this rate, the Federal Reserve buys and sells Treasury Securities. By buying up Treasury Bills, the Federal Reserve puts money back into the system, where does Uncle Sam get the money to buy these? They have 2 options, first Tax us to take it from us, not a very popular option because people can only be taxed so far before they've had enough. Secondly, they can just print money on their printing presses. (Both methods are of course illegal for us to do)
Since we are off the Gold standard, the value of the dollar is based on whatever the markets say it is. If there is a surplus of dollars, the value of them goes down. When we were on the gold standard, it basically meant that the US had gold in it's vaults to back up the money it was printing. (The printed money was basically an IOU for gold or silver because let's face it... it's a lot easier to carry around paper than gold)
Ok, so now the dollar doesn't buy you as much as it used to but unless you are in the government, your salary probably hasn't gone up. So what does that cause you to do? We aren't the Federal Reserve so we can't print money, we aren't the IRS so we can't steal it, that means we have to either find a higher paying job or cut back your spending. By not spending as much the GDP goes down.
Also by not spending as much, businesses do not make as much money because people aren't spending as much. Some businesses do better than others but ultimately as people buy less, business can't afford as many employees and have to lay people off. This makes the unemployment rate increase.
Now the above are the first two steps of the Scientific method, state the question and then doing some background research to find a way to create a hypothesis. If anyone got this far, do you think that the hypothesis they would come up with would be print more money by lowering interest rates or taxing the people? Some people feel (because the media and the Government told them so) that the reason for this mess is because of deregulation. So they call for more regulation, more government spending, a newer new deal of sorts. Some felt the new deal was a great success, others (myself included), felt that all the new deal did was prolong the depression and that it was WWII that created the jobs to get us out of the depression. Who should you trust? No one, do some research for yourself. Just remember, some of the legacy programs from the new deal are FDIC, FHA, TVA, Social Security (nothing but a Ponzi scheme), SEC and Fannie Mae.
And for those of you who say this was unexpected, no one could have predicted what happened... take a look at the Austrian School of Economics. Specifically, take a look at one Congressman who has it right. In fact to make it easy for you, one blogger made a nice collection of his works available for you: http://valuefreedom.blogspot.com/2008/05/ron-paul-told-us-so-economics.html. If you want more info on this, visit mises.org.
And it doesn't matter if you are a republican or a democrat or an independent, this is an issue that affects us all. In fact I seem to remember Obama, McCain and Bush all saying the same things about the banking and auto bailouts that most Americans were against. If you disagree with me then fine, everyone is entitled to an opinion, just don't say no one told you.

iPhone ringtones
Have a cool audio file you want to use as a ringtone on your new iPhone but can't figure out how to get it to work? Don't want to spend $0.99 on a ringtone from apple for a song you already have and want to use your fair use rights? You can do it, I can help.
Ok, as I say to my daughter, the easy way or the hard way? I'll start with the hard way first so you have a basic understanding or don't have garage band... if you do and are impatient, just skip ahead.
First you need an audio clip. Anything will do, we will be converting it to AAC format so if you have one of those, great. (not sure about the copy protected ones though... you have to be able to edit the file) If you do have an AAC file, cut it to 30 seconds or less and you can ignore this next bit.
Of you don't have an AAC file, you'll need to make one. Open your favorite audio editor, I've been using Audacity because it's free but you can use pretty much any audio editor, we don't need any fancy features so I'm sure you can find a free one on just about any platform that will do.
Now, load up your file and find the 30 second (or less) sound clip that you want to use. Got it? Ok, save those 30 seconds as either an AAC format or, if like me your editor doesn't support that, choose an uncompressed audio format. Then to convert to AAC format, load the uncompressed audio file into iTunes and right click and select convert to AAC. If you don't see this option, you probably changed it in your Preferences section of iTunes under Advanced->importing and then change the "Import Using" option to AAC. Now you'll need to right click and choose show in finder to find the aac file and copy it somewhere temporary. (I use the desktop) Now delete the new files it created from iTunes. (but not from the desktop)
Ok, now you have an AAC file on your desktop and not in iTunes. Rename the file from YourFilename.m4a to YourFilename.m4r. Load this file into iTunes and it should go into your ringtone list. Sync your phone and you should now have your custom ringtone on your iPhone.
Have GarageBand? Ok, this is really easy. Choose the loop button next to the FFW button on the main controls. Now, you should notice a small section appear below the timeline, use your mouse to select the 30 second clip you want, then choose Share->Send Ringtone to iTunes. Sync phone.
Apple could have made this a lot easier, especially for users that don't have garageband. I mean, why not just let us use mp3s as ringtones? This is one area where I think apple really dropped the ball. Fortunately I have garageband so it's not a terrible process, I just think $0.99 per ringtone is a bit ridiculous especially because you can buy the whole song for that.

iPhone review
Well my script actually worked and did score me an iPhone. Ran it and noticed the Short Hills mall had all three versions in stock and my wife went over. Turns out I had to be there to because I was the primary on the previous account so I left work a little early.
First impressions are that it's awesome. The main reason I got it was for the integration between it and the mac. So far everything has been seamless. I first went into the mail app on the phone at the mall so I hadn't synced up yet. First, you select Gmail, put in my gmail username and password and that was it. I saw no apparent way to add other mail accounts and was a little bummed at first. My fears were for naught as when I later synced with my mac, it pulled in my other mail account. Right now I can just pull but there are services to push (MobileMe being mac's solution) but I'm not that concerned about it yet.
Calendar integration is seamless as well. Syncing with my mac synced all my schedules to the iPhone. Haven't had it that long to tell if there are issues, none have popped up yet so we'll see. Same with my contacts from the Address Book. The only downside was I hadn't updated address book in a while so some of my numbers weren't in there. Definately not the phone's fault though.
There are a lot of apps available on Apple's AppStore, some are free, some are reasonable and some are outrageously priced. I'll start with the free ones first.
Pandora - This is the online radio station pandora. It's free but amazing. Experienced a couple hickups on the way to work this morning where only part of a song played and then skipped. (I'm guessing didn't fully download or something) But for the most part worked well for my commute. I highly recommend this app.
MobileNews - This is basically just a news source for Associated Press news. I've avoided the NYT app because people seem to be complaining that it's slow. MobileNews has been pretty good. My area is not supported for the "Local News" feature and the interface could use some polishing but it's not bad. They also have a web based version which is optimized for the iPhone.
AIM - AOL instant messenger for your iPhone. This was actually the first app I installed to let my coworker know I got an iPhone. Not spectacular but not terrible. Basic instant messaging.
Tomatoes - This is the Rotten Tomatoes website's app. Starts with a text box for you to type in a movie. Typing in a movie then searched for that movie in their database. Gives you a basic summary of the movie and their rating. Summary is only one iTunes screen high. Clicking on the movie name at the top brings you to the web page for said movie but in doing so, exits the Tomatoes app and brings you to the Rotten Tomates page for that movie. Probably wouldn't be terrible if the page it takes you to was optimized for the iPhone but it's not. Will probably use as a quick reference for movies I'm not familiar with. Could be better.
PhoneSaber - Ok, no point to this, it's a lightsaber, you can pick your color beam and swing your iPhone around to make lightsaber sounds. Pointless and a waste of space but I still have it on my iPhone to uhhh... show people how useless it is, yeah, that's it.
Now for the paid apps, these are ones I've actually spent money on. To be fair, I have a credit card that gives me reward points in iTunes cards so I haven't really paid for it, but in a way I have.
Crash Bandikoot Nitro Kart 3d - Graphics are very good and you tilt the phone to turn. Very addictive. Nice use of the controls.
Monkey Ball - Another pretty cool game that uses the motion features of the iPhone to tilt the platform. This moves a monkey in a ball and you go around picking up bananas. A little tricky to get used to but fun.
Well that's it for the Apps I'm going to review today. I have a few more apps on my phone but haven't used them enough to tell if I like them or not yet. So stay tuned. Overall the iPhone has not disappointed.

iPhone availability
UPDATE: Looks like apple changed the link to a PHP page. Not sure of all the details, maybe they are actually checking the time on the server end instead of just relying on some javascript. Oh well, I got mine. :-p
So my contract is finally up with Sprint so I can now leave them without paying any penalties. Avoid sprint like the plague. Nextel was decent until they merged with Sprint, but that's a much longer rant than the cool info you'll find below.
So I've decided to ditch Sprint in favor of AT&T, primarily so I can get an iPhone. Apple has an iPhone stock bit on their web page. Go there after 9pm and you can see if a store is expected to have an iPhone in stock the next day. I do not always get on my computer after 9 for whatever reason so I thought I would script something to just scrape the page and see if the store will have it available. I found something even better.
http://www.apple.com/retail/
Go ahead, find a store near you and look at the source, I'll wait. See it? Yes, that bit of javascript where it calls: http://www.apple.com/retail/iphone/feeds/3g_us_inv.json
That file appears to not only have if there will be an iPhone available, it also has which models it expects to have available. The only other thing I could wish for would be the quantity, but now I'm expecting too much.
So what do we do with it? I'll show you what I did. First, we'll use python because it's cool and makes stuff like this easy. Second, since it's a json formatted file, good choice apple, we'll use simplejson. Got all that? Good, let's script this sucker.
Ok, that basically downloads the json file and parses it into a nice little python data structure which we called availability. Now, I'm really only interested in certain stores in NJ. So, I do a loop like the following:
There seems to be available: url, city, storeid, available. Available then lists each type of iPhone (white16, black8, black16) and a true/false if it is available or not. So go forth and script to your heart's content. To be nice, here my final script:

Using git
Things I like about git over subversion.
1. Branches are easy... no, really easy, just do a branch for every feature. Go ahead, you know you want to. 'git checkout -b coolfeature' It's just that easy.
2. Only check in part of a changed file. 'git add -p' It then prompts you line by line if you want those changes added or not.
3. It's fast!

Firefox Extensions
Here is my list of firefox extensions I use.
Firebug - The coolest extension i have for firefox. I use this to debug javascript and css all the time. If you develop for the web at all, you need this tool!
Tamper Data - Change things like POST variables. Primarily used for testing purposes.
Aardvark - I use this primarily to remove elements from a page before I print it.
MeasureIt - How long is that box and why doesn't it match my css?!?!? This tool helps you measure elements on the screen.
Download Statusbar - Get rid of that extra window, see your downloads at the bottom of the screen.
DownThemAll - Helpful for sucking down all the images from a page. (Even if they are links to images) Also has a few other advanced downloading capabilities.
Dummy Lipsum - Let's you insert Lipsum into a text box.
Foxmarks Bookmark Synchronizer - Synchronize bookmarks between computers. What's special about this is that you can use your own server so you don't have to sign up for another account somewhere.
Greasemonkey - Allows you to write or download scripts that alter web content. Sounds confusing but there are a lot of nice scripts out there to make the web a better place.
Html Validator - Useful tool to make sure your web page validates according to the W3C standards. Even works on pages that are not publicly accessible.
LinkChecker - Checks all the links on a page to make sure they are still valid.
NoScript - Stops javascript except for pages you allow. Can be annoying at first but once setup properly, reduces your chance of getting infected by malicious javascript.
Torbutton - Nice way to activate/deactivate using Tor.
Web Developer - Some useful tools that a web developer might find handy.
YSlow - Used in combination with firebug to determine how efficient a site is. Don't take everything at face value though, your little blog probably doesn't need a CDN. Also seems to now come with a javascript validator.

Greasemonkey - Allows you to write or download scripts that alter web content. Sounds confusing but there are a lot of nice scripts out there to make the web a better place.
Html Validator - Useful tool to make sure your web page validates according to the W3C standards. Even works on pages that are not publicly accessible.
LinkChecker - Checks all the links on a page to make sure they are still valid.
NoScript - Stops javascript except for pages you allow. Can be annoying at first but once setup properly, reduces your chance of getting infected by malicious javascript.
Torbutton - Nice way to activate/deactivate using Tor.
Web Developer - Some useful tools that a web developer might find handy.
YSlow - Used in combination with firebug to determine how efficient a site is. Don't take everything at face value though, your little blog probably doesn't need a CDN. Also seems to now come with a javascript validator.
Essential OS X Widgets
This list will be short because I really don't find most widgets to be all that useful. These aren't necessarily "essential," just ones I use.
iCalEvents - This looks at your iCal events and displays upcoming ones. While I use my MenuCalendarClock more, it's handy to have when I'm in dashboard.
Weather Underground Widget - Shows you the weather forecast. While I still don't trust meteorologists... (where are the meteors?!?!? They must be hiding them.) I find I trust these guys a little more than the average meteorologist. Handy to see upcoming weather.
Aviation Weather Widget - Using this primarily to learn how to read METAR data.
The Analog Clock Widget - Just because.
Homer Quotes - A little humor.
Stickies - Keep little notes. I primarily use the Stickies.app for most things but I have a few things on my dashboard sticky.
iStatPro - Cool widget to display various system info.
I have others installed but never really use them. I feel that once I get an iPhone, most of these will fall into serious disuse.

Essential OS X Software
There have been a few people who have gotten mac's lately and I'm getting tired of forgetting to recommend a really cool app to them. Therefore I've decided to create my essential OS X application list. These are all applications that I feel are vital that do not come with the OS. I'll cover useful built in ones, widgets (both included and add-on) and Firefox plugins later.
Open Source or Free software:
Adium - Open Source multi-protocol instant messenger application. Really good instant messenger program. Does not do Audio or Voice so I still occasionally use iChat but otherwise, I use Adium.
Burn - A free tool to burn DVDs and CDs. Sure, you can do most with the built in OS X tools but this makes it a lot easier. Also it's free so uhh... go install.
Chmox - Ok, it's not great but it's the best chm reader I've found. It really needs the ability to search though. Plus it's a native OS X app so no need to have the X running or anything.
coconutBattery - Not really essential but shows you how badly you've abused your batter. Nice to know your not going insane and your battery really doesn't last as long as it used to.
Firefox - If you don't know what this is, come out of your cave, it'll be ok. If you haven't already go get this. Safari is nice but the plugins available for this make it really shine. I'll go over essential plugins later.
Google Earth - Another non-essential app but fun none the less.
Handbrake - Want to take a DVD with you, don't want to save a 4Gb iso? Convert it down to something a little more reasonable with this tool. Will also convert to iPod formats for really portable movies.
Miro - Like TV, for your computer. This lets you download most video podcasts and has a nice little directory of them. Can also be used as a torrent downloader so you could subscribe to your favorite TV show at say tvrss.net.
Growl - System message notifier. Ok, doesn't sound like much and probably won't change your life, but there are a lot of applications that will send notifications to growl to display. Useful to let you know at a glance when something is done downloading, you receive a new IM or E-Mail. Handy tool to know if something needs attention now or if it can wait.
NeoOffice - This is a macified version of open office. If you are like me, you don't deal with office documents that much but every once in a while someone will send you one. While some features are missing, I haven't noticed anything I really miss. Especially good for the casual user. If you really need to, Office is available for the mac, but this is a good free alternative that is worth trying out.
Quicksilver - In a nutshell, it's an app launcher. Though that's not doing it justice. I use this all the time but it did take me a while to get used to it. I had to force myself to start to use it and then discovered it's power. Can really speed up the time it takes you to do things. Worth watching a few tutorials and trying it out. Lots of hooks into programs (like the address book, mail, iTunes, etc...) to make it really useful. I can't do it justice, search about it and give it a try!
sshfs - If you use ssh, this is cool. Allows you to create a drive mapping that is really just an ssh connection. If that doesn't make sense to you, you can probably skip this app. Will probably need to install MacFUSE first.
Transmission - Lightweight Bittorrent app. If you use bittorrent at all, this is a handy application to have. It's lightweight and pretty full featured.
Truecrypt - Open source tool to create/mount encrypted volumes. Can also be used to encrypt entire USB flash drives. Keep your private data secure!
Tunnelblick - I have mixed feeling about this, it's a bit buggy and crashes on me all the time whenever the network hiccups but it's a nice easy way to get OpenVPN on your mac. Even gives you a little icon in the menu to connect to your servers. If you don't know what OpenVPN is, you can safely do without this. If you use OpenVPN, this is a nice tool to have.
Vidalia - Tool to use Tor. I don't use it that often but if you're looking for anonymity online, it's the first place I would start.
Vienna - RSS/Atom reader. This is how I get my news and my daily Dilbert fix!
Vim - Text editor based on good old vi. I'm sure most people will not really use this but I find it essential. A bit of a steep learning curve, but once you learn it, you won't want to give it up.
VLC - This video player will play almost anything. Much better than quicktime or iTunes for playing videos. Will also do audio for when you want to listen to a song (or audio stream) without adding it to your iTunes library.
X-Lite - Free SIP based softphone. If that makes no sense to you, you can probably skip it. Not the best app I've ever used but so far the best softphone I've found.
Commercial Software:
With quality open source software out there, I don't like paying for software when I can help it but sometimes something really good comes along and I just have to suck it up.
MenuCalendarClock - This beefs up your clock to add a calendar that integrates with iCal. It's very cool and there is a free version so go check it out. At the very least, go look at the preview pics on the site.
Adobe CS3 - Let's face it, if you deal with graphics, you need this. I shouldn't have to say any more and it's one of the main reasons I tried a mac in the first place. Ability to install Photoshop and have all my Unix tools, I'm in!
iBank - Personal finance program. I tried using Quicken, I just had issues downloading from my banks and gave up. iBank doesn't have all the same features yet but I've been able to download from my banks pretty flawlessly. Very mac-like interface as well. (Tip: put the ibank file on a truecrypt volume (see above) to keep your banking records safe)
iWork - Ok, I guess now I'm really turning into an apple fanboy. Very much presentation oriented. Does not have all the features of their office counterparts but can be used to create really great looking spreadsheets, documents and presentations. Combine this with the open source neo office (see above) for those office docs people send you and you should be set.
Mac the Ripper - I put this in the non-free section because while there is a free version, you really need version 3 which seems to not be free. Though if you look hard enough, you should be able to find version 3.0_r14 without too much difficulty. Helps you get around most copy protection and then you can use handbrake (above) to reduce the file size.
OmniGroup - There are a bunch of apps here, some better/more useful than others. If you are a Getting Things Done fan, definately check out OmniFocus. I just started playing around with it so we'll see how useful I find it. OmniGraffle is a good replacement for Visio if you need to do diagrams. I've used it a little but I don't make a lot of diagrams. I'm going to try and use it more to make better documentation. OmniPlan is a good project management app that I'm also going to try and start using to get organized.
Transmit - Ok, I resisted this for a while, used FUGU (which isn't bad) but as an all-purpose FTP/SFTP client, this really can't be beat. Simple interface, easy to use. If you transfer a lot of files, this is a really nice app. If you don't FTP/SFTP a lot, then you can probably do without.
VMware Fusion - Ok, I don't use this to run windows, but I do run linux on my mac with it to test things. One day I will probably use it to run windows on my mac for IE testing purposes but I've been putting that off because I really just don't want to use windows anymore.
VueScan - Utility to interface with most scanners. I find this to be better than the tools that come with most scanners. Still not great but so far the best scanner utility I've used.
Open Source or Free software:
Adium - Open Source multi-protocol instant messenger application. Really good instant messenger program. Does not do Audio or Voice so I still occasionally use iChat but otherwise, I use Adium.

Why I need to get out of NJ
The superintendent of Keansburg schools is about to receive a ridiculous severance package. The school itself is a poor school that receives most of it's funding from state aid. First, she's getting $184,586 for 235.5 unused sick days. That works out to about $784 per sick day. I don't know about you but when I left my last job, I only got to cash out my unused vacation days for the year, any leftover personal time was not paid out. Plus it didn't carry over from year to year to accumulate 235.5 days.
On top of that, she's getting $120,000/year retirement pay. That's more than I, and presumably most of the parents who's kids attend the school's, make working for a living. I'm not saying she's not entitled to something but that's a little ridiculous.
But wait, there's more, she is also getting $556,290 which is her monthly salary times the number of years she's worked there (38) as a bonus. That means her monthly salary was about $14,639.
If this is what the superintendent of one of the poorest schools in the state gets, it's not wonder we have high taxes. I really think the state needs to publish all the salaries of every state employee so we can see how much we are getting ripped off. If I understand it right, the state does provide this information currently but you need to know the sate employee's name to get the information. And there's probably a processing fee for each person. If we really want to do something about taxes, let's start by re-evaluating state employee's salaries.

Dissatisfied Voters
The title "Zogby Poll: 48% of Voters Dissatisfied With Candidates" I think says it all. I know that I am not satisfied with any of the candidates still running with the exception of Ron Paul who at this point does not have a chance to win the Republican nomination. Now imagine if instead of voting for the lesser of two evils come election time, those people actually voted for a 3rd party candidate. Even if they didn't win, it would certainly send a message that the country is not happy with the direction the company is headed.
When people tell me that a vote for candidate X is a vote for the lesser of two evils I always tell them that a vote for the lesser of two evils is still a vote for evil. I then ask, "Who would you vote for Hitler or Stalin?" Personally I'd vote for other. The democrats want to take away my guns and redistribute my money while the new republicans want to take away my liberty. I think this year is an excellent year to not vote for Fascism or Communism and instead vote for other!

Gun Free Zones
Are "gun free zones" really safe? This article has some food for thought and finally got me to start blogging again. I've been thinking about this issue for a little while now and have some thoughts on it. It doesn't matter if you read the article first or read my comments below first, they are related but not dependent on one another.
A number of states have concealed carry permits (often abreviated CCW) available to law-abiding citizens. There are different requirements and it varies by state to state but some form of concealed carry is currently available in about 48 states. (As of Feb 2008 according to wikipedia) Vermont and Alaska don't even require a permit, any non-felon can legally carry a concealed firearm.
But what about the shootings in the street? Complete mayhem I tell you... Some opponents of CCW tell you that there will be more violence than before but that hasn't been the case. One reason is that if you mis-use your firearm in any way, you can have your CCW taken away. And let's face it, those who are going to follow the law (by getting their CCW to carry in the first place) are more than likely going to continue following the law by not using it in an illegal manner. Those that ignore the law anyway (by carrying without a CCW) are the ones you really have to worry about.
Imagine how different Columbine or Virginia Tech would be if one teacher had a concealed firearm. Or, since Virginia Tech is a college with students eligible for CCW, one student who could have stopped the mentally ill students who felt the need to go on a killing spree. In fact at Virginia Tech, there were students who had their CCW but were not allowed to take their weapons on campus.
I'm not saying everyone should be armed, there are people out there who are mentally unstable who if they had a firearm would most certainly be a danger to themselves and others. There are also criminal types who are going to ignore the laws anyway and then there are those who are just uncomfortable with the idea of having a gun. That's fine, I can completely understand, firearms are not to be treated lightly. In the wrong hands they can be very dangerous and if you are uncomfortable handling one, I don't think you should be forced to. On the flip side, if I am comfortable in carrying a firearm to protect myself and my family, I should be able to.
But don't take my word for it, go out and do your own research. There is a lot of information on this from both sides of the argument. Keep in mind that a lot of studies (from both sides) have certain agendas they are trying to push. Look at the studies, look at the stats and come up with your own opinion.
