I had received this printer after Thanksgiving since my dad wanted it no more. He gave me a D-Link DP-301U and a HP LaserJet 3200, a USB printer, and a USB network print server. Now, as almost any sane person knows printers are some of the most fickle beasts on this planet, and taming them is a task that no mere man is prepared for.

How many hours did you waste trying to stop a printer from printing some document, only to have to go to the emergency room because you needed stitches for the gash on your forehead?

I am fairly sure that with the amount of time and productivity lost to dealing with printers we could have solved world hunger, or at least cured cancer.

So after putting off this printer installation for many a month, for fear that I would end up losing all my hair as I pulled my hairs out one by one, I needed to print something, I had to finally cave.

I plugged in the printer, and I heard it whirl to life, the sounds instantly causing PTSD flashbacks to the many printers I have had the displeasure of turning on. I plugged the printer into the print server, plugged the print server in, and found myself silently praying, not merely praying but also slowly and surely rocking myself back and forth as if trying to calm myself.

After opening System Preferences, and adding the printer, selecting that it is a LaserJet, it said it had successfully added the printer. It has always seemed so deceptively simple, a couple of clicks and bam it should work. Surprisingly no drivers needed to be downloaded, no hundreds of megs worth of extra crappy software installed, could it be this simple?

I opened the file I wanted to print and started preparing for the worst. I had my hand on the paper tray, knowing that if it goes wrong this printer will go through 500 pages attempting to print pages of garbage, I hit print and immediately moved my hand to the power button, as an even better last resort. I tried to push the memory of older printers and how they had wronged me out of my mind as I got another flashback as the printer started spooling up, readying itself to print.

What happens next is somewhat of a miracle, the printer spat out my document, a perfect reproduction on paper. It didn't attempt print hundreds of pages of random characters and garbage, it didn't eat the pages and jam, it didn't start beeping at me because of the wrong printer drivers, my fears were unfounded.

Today is a great day, it is the day that I can start rebuilding my faith in printers, no longer afraid, no longer needing to worry about stitches, or that it really hurts to rip hair from my head. Today the printer gods smiled on me, and I smiled back.

Recently I was going through domain registration again and I was looking at a list of domains that I wanted, but couldn't get because at the time I looked they were already taken. I got lucky, I finally got funcptr.net/com and immediately purchased the two.

So without further ado, I introduce my new technical notebook named funcptr which is where I will be writing longer length, well thought out (hopefully) articles. The whole idea is for me to start writing down the solutions to technical problems I have encountered in both software engineering as well as system administration and various other technical tasks. It won't be strictly limited to software but will also include hardware projects, and electronics.

I hope you go over and take a look. I am slowly but surely migrating technical content from this blog to funcptr such as my NAT with pf on an interface with multiple IP addresses article that describes a problem I ran into with PF automatically enabling round-robin causing issues because the secondary IP address was not on the same network as the default gateway and thus NAT didn't function as you'd expect. I am setting up 301 redirects so if you have linked to a post here before, don't worry, it will transparently send you to the correct location!

Let me know if you have any suggestions, you can find my contact information on my portfolio site: contact Bert.

He was always a step ahead of everyone else, knew what people wanted before they wanted it and was able to give it to them in beautiful product that people fell in love with; and still do fall in love with.

You may disagree with his business practices, you may dislike him, but he lived the American dream. He started from nothing in a garage and ended up as the CEO of one of the biggest and richest corporations of our time. We may not be able to follow in his footsteps, we are at least able to gain wisdom and knowledge from his experiences and missteps so that we too may one day be as great of a man as he was.

He did what he loved, he ran Apple until his last breath. I hope that one day I may be so lucky as to say that I too did what I loved until the day I died. May we all be so lucky as to die doing what we love surrounded by loved ones and friends.

At the end of Stanfords Commencement address in 2005, Steve Jobs quoted a magazine he used to read called the "Whole Earth Catalog", and they said on the back of their last issue "Stay Hungry. Stay Foolish".

It is one of the quotes that has stuck with me from that address, it is something that I truly believe in. It is something I attempt to follow every day. Every person interprets it differently, and that is the beauty of it. I find it apt then to end this article by thanking Steve Jobs for bringing my attention to these four words and how they have changed me.

Thanks for everything Steve. You made a huge dent in the universe, I can only hope to scratch the surface compared to what you accomplished. May you rest in peace.

Stay Hungry. Stay Foolish.

1. DHCP assigned network that routes to the outside network on the host (192.168.0.1/24)
2. An internal to the VM's network interface (10.99.12.1/24)
3. A network that is tied to the hosts wireless network (setup to be an AP) (10.99.11.1/24)

So within my FreeBSD VM I have the following: em0, em1, em2 as "network cards". In my FreeBSD VM, I am creating two jails that are going to contain different pieces of server software. The jails need ip's in the following ranges, 10.99.12.1/24 (to connect to another VM), 10.99.11.1/24 (Wifi network) and then it needs to have an IP address that is considered "local" and we can NAT on, so in addition to the above networks we also needed to add another network. The easiest way to create new interface with IP address' is using a bridge. They can be assigned IP addresses, which is all we need.

At this point inside of a jail it kinda looks like this:

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC>
    ether 52:54:00:6b:6a:49
    media: Ethernet autoselect (1000baseT <full-duplex>)
    status: active
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC>
    ether 52:54:00:2f:a5:55
    inet 10.99.12.4 netmask 0xffffffff broadcast 10.99.12.4
    media: Ethernet autoselect (1000baseT <full-duplex>)
    status: active
em2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC>
    ether 52:54:00:bb:b6:43
    inet 10.99.11.14 netmask 0xffffffff broadcast 10.99.11.14
    media: Ethernet autoselect (1000baseT <full-duplex>)
    status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
    options=3<RXCSUM,TXCSUM>
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether da:de:63:c9:55:6c
    inet 10.0.1.4 netmask 0xffffffff broadcast 10.0.1.4
    id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15

    root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0

em0 doesn't have an address since that is our DHCP address, em1, em2 and bridge0 all have IP addresses, in the jail configuration the bridge0 IP address is listed first, and thus when something binds or sends it sends from that IP address. The thing is that at this point the jail does not have internet access.

Jail's inherit the routing table from their host environment (yes, you can compile in more routing tables ... but I don't want to modify stock), any traffic that goes to the outside is going to go out over the default route, thing is you'd expect that traffic to show up on bridge0 where the IP address exists, instead using tcpdump you see it show up on em0, which is where the default route is. I would have expected having to do NAT on the bridge, not just the external interface.

Here is the pf configuration.

ext_if="em0"
jail_if="bridge0"

set optimization aggressive
set block-policy drop
set skip on lo

nat on $ext_if from $jail_if:network:0 to any -> ($ext_if)

pass quick all

And we've got internet within our jail. I am looking forward to setting this all up when the new VIMAGE stuff lands in 9.0-RELEASE so that I can have virtual network cards that are not tied to a physical network card!

Overall StackOverflow has done an outstanding job in doing what their core mission statement was when they started it, and recently has begun branching out into various other territories using the brand name StackExchange. I am very happy that these sites exist, and that they provide much better results for the same questions.

Today I was reading a blog post created by Joel Spolsky, titled "The Wikipedia of Long Tail Programming Questions", in it he brings up some core features that StackOverflow supports, such as everyone editing community questions at 100 rep, and editing any questions or answers at 2000 rep. Rep in this case can be compared to karma on Reddit or Slashdot. Rep is earned by answering questions accurately and having other users "upvote" your posts. Rep may also be lost, but that is outside the scope of this discussion.

• Some of the suggestions that Joel makes are as follows:
• Don't answer questions that have already been answered elsewhere.
• If you're going to close a user's question as a duplicate, it has to be a real duplicate.
• It is OK to edit a question to make it more general.
• Help us build a great library of canonical answers.

I agree with all of them except the first. Now, if you quickly take an interlude from this blog and go check out my StackOverflow profile page you'd see that sometime in March (only for two days actually) I suddenly became very active on StackOverflow answering a lot of questions and helping many people, and gaining reputation rapidly. It was shortly thereafter that I slowed down, mainly because the rate at which I was going was only possible because I was on school break, and because I started working on some new projects. Since then every so often when I stumble across a question I will attempt to answer it.

In attempting to adhere to number one as outlined above I tend to do some searches to see if maybe the question has already been answered elsewhere, and also to adhere to number two it takes me at least a minute or two per question.

Then scenario one is as follows: During that time others are doing the same, or maybe already know it is a duplicate and close the question (hopefully linking to another question that it duplicates), those are two minutes I just spent doing some research to provide a better answer that is then not necessarily wasted, as generally I will learn a thing or two, but at the same time I wish the submitter had searched for himself.

Scenario two is as follows: However if the topic is not closed, and is a fairly simple question during the time that I am doing my duplicate search others will have posted a one or two sentence reply that will somewhat help the author of the question. Those will then get upvoted rapidly as people consider those easy questions answered. At that point I will type out a full thoughtful reply that will get ignored and will stick around at 0 upvotes as people don't tend to come back into questions after it has already been answered a couple of times.

This has made me apprehensive of answering questions as they come up on StackOverflow as generally those that I feel qualified to answer will get glossed over and there is really no incentive for me to continue doing so unless I go for the long tail (hope that within the next coming years people find the reply through Google and upvote it then). I feel that the quality of responses on StackOverflow has gone down mostly because you can get one or two upvotes before scenario one plays out and the thread is closed. This means that on duplicates it becomes who can quickly answer and post (hence the one or two sentences) before the mods get around to it. While I really enjoy responding and that should be enough to entice me to respond more, I feel like I am being alienated by lesser quality posts that don't provide nearly the quality that I have come to expect of StackOverflow.

The answers are starting to look more and more like those on Experts-Exchange, the barrier to entry is very low on StackOverflow, mostly on purpose but I also feel that it detracts from the quality the website is required to have to stay useful in the foreseeable future.

One way I can see this being "fixed" is Slashdot style (for people who want to "moderate"). On Slashdot before you get mod points you have to do a couple of different tests to see if you are in-line with the majority, you get to see comments and context and you have to decide what you'd moderate the comment. On StackOverflow a newer user before being given the ability to upvote/downvote answers would then have to first do a small test to see if they are able to decide what is a good comment and what is a bad comment. Then when they start posting other users will judge their replies, and if they are short and don't contain a very good answer they are limited from posting replies in threads that are newer than X minutes. This would give the power users that have earned it the time to do the proper research, write out a good reply, or close the thread as a duplicate without people being able to farm for karma by posting two sentence replies that are completely useless.

Is this feasible to implement? I don't know. Would it provide a higher barrier for entry, absolutely. I think that is a good thing. In closing, I would like to state that I absolutely love the various StackExchange websites, and the ease at which knowledge is now spread, but I have been becoming more and more distanced from the website since the quality of answers went down tremendously, and I am much less likely to spend time answering a question when it is already saturated with one or two sentence answers thus having my quality answer sit at the bottom of the list at 0 upvote points.

left border width + left margin + left padding + width + right padding + right margin + right border width.

Well, that off course does not work well when you want to float two items next to each other with the following:

#cont1 { float: left; width: 75%; border: 1px solid black; }
#cont2 { float: right; width: 25%; border: 0; }

These will not float next to each other since #cont1 is bigger than 75% meaning that the other one being 25% gets pushed beneath it.

CSS3 fixes this with the box-sizing: border-box;, this property will make it so that all of the padding, margins and borders are calculated within the allocated width, that means a width of 75% means the entire element will be 75% and everything else will be calculated within it.

You can use it now with the following snippet:

box-sizing: border-box;

-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;

However IE won't render the boxes correctly, nor will older versions of Safari, Chrome, or FireFox. Until CSS3 is ratified and starts being accepted by all major browsers without the browsers specific keywords it is not really that useful. In my case I have reverted to the alternate version of using a wrapper element that wraps around the element, and doesn't have margin, padding and a border.

#cont1wrap { float: left; width: 75%; border: 0; margin: 0; padding: 0; }
#cont1 { border: 1px solid black; }
#cont2wrap { float: right; width: 25%; border: 0; margin: 0; padding: 0; }
#cont2 { padding: 10px; border: 0; }

It does mean that you need twice the amount of tags in HTML, one with an id of #cont1wrap and another inside of that with an id of #cont1, same with #cont2. Not an ideal solution but until CSS3 is made the new king of layout it is the only choice we have that is mostly compliant with most browsers.

He has taken this message to Huntington, West Virginia where he was met with resistance and close minded people who did not want to make a change because of how it had been done for years. Jamie kept going even with the amount of resistance, he persevered and after just two episodes of his new TV show "Jamie Oliver's Food Revolution" available on Hulu (watch the episodes).

He was also recently awarded a TED prize wish, to teach every child about food, where he discusses some of the things he encountered in his first episode of the TV show.

Jamie has a petition available on his website, and I urge you to go sign it to show support for not just a healthier United States, but World in general. Teaching people how to cook for themselves is an absolute must, having people learn how to take care of themselves, what goes into their food, and what goes into their bodies.

I'll be the first to admit that I am not the healthiest person, and yes the first two episodes of the show hit close to home, I don't always eat the healthiest food I can find, especially since I don't always like cooking for myself, and fast food is so much, faster and easier.

My wish is for Jamie to succeed in helping change the way the United States looks at food and what is acceptable for people to put into their bodies. Getting rid of even 10% of all processed food will make the United States a healthier place to live and eat, and will lower healthcare costs in the long run as less people will need medicine and medical procedures to help them stay alive because of the amount of grease in their arteries.

Once again, I urge you to please go sign the petition, watch the TED prize wish, and watch the TV show. And if you too, are in the same boat I am in, start making a positive change in your life.

It is my hope that eventually they fix it and just leave the save function enabled and if the file doesn't need saving they don't save it. That way my I don't have to listen to "ding" thereby breaking my concentration.

To see everything that IE9.js supports visit the IE7.js Test Pages list and take your pick. The work that Dean has done is absolutely amazing and I am very happy that because of him I don't really have to worry about my websites in older versions of non-standards compliant browsers.

Even Microsoft sent flowers to the fake IE6 funeral with a note saying that we should stay tuned till this years upcoming MIX conference. I hope they say they are support HTML 5 and CSS 3 as that would be simply amazing. Maybe, just maybe they are switching from the old Trident based rendering engine to something more modern.

While I may dislike IE 6 and 7, I won't yet go so far as to put up a message just yet stating that people should get a better browser, I am removing a lot of stress and work in that I no longer have to support the old ageing browser.
