Technology: Can Technology Relieve Gas Prices?



This probably caught my eye mostly because I just filled up my truck.  Gas prices are climbing higher and higher, and any hope of relief looks good.

This article describes a project that might help.  Erik Koepf is designing a process that does not require fossil fuels to create the hydrogen.  Maybe it might start us on a path toward oil independence?

You can read about it in the following articles:

Maybe I don’t understand all of the articles, but I don’t see anything that makes hope for soon relief.  At least, someone seems to be making progress.  Until this technology reaches consumers, we may need to turn to things like WVO.

Or, if you want a cooler alternative, here’s a floating wind turbine:

Fun Fact: Gamers Can Be Eccentric

I just ran across these two different articles from Engadget, and it struck me funny.

First, you can play a more realistic Frogger using technology that can bring the real traffic into the game.  ”Real Cars. Real Time. Fake Frog.”  Check it out:

Engadget: Fifth Avenue Frogger brings everyone’s favorite roadkill to New York City (video)

Or, you can play Tetris on the side of a building.  The only thing they didn’t do is take the controls out on a public sidewalk and let passers by play.  Check it out:

Technology: Flying Cars

We’re getting closer to the Jetsons every day!  Flying cars are something I only thought of as science fiction, but it looks like Terrafugia might be working toward making them a reality.

I saw this article with some nice pictures of the Terrafugia Transition.  They do a good job of pointing out that it is really a plane that is street legal.  Check out the blind spots on that thing!  Driving a $250,000 piece of machinery is a scary thought in some places, too.

If you want to see more or sign up for one, you can check out Terrafugia’s own website:

To me, this is the perfect plane for something like the Sun N Fun event in our neck of the woods.  Attendees could fly into the event and not have to rent a car while staying in Lakeland.  Sure, you wouldn’t want to drive around much in the airplane, but most of the activity is at the airport anyway.  Apparently, Terrafugia thought the New York car show was more import as you can read — AOPA Online: Terrafugia skips Sun ’n Fun for auto show.  It’ll be interesting to see in the next coming years if we start seeing these planes around the area during the Fly-In.

Computers: Browser Quest

I ran across this new game online.  Apparently, Mozilla is showing off new HTML5 technology, but it is still kind of fun to play.

Technology: New Possible Efficient Airliners

This article caught my eye on Engadget.  Just recently, one of my plane tickets was over $1,000!  If technology could make the fuel cheaper, we might be able to fly more.  But then again, would the airlines really pass the savings on to the consumer?

Review: Religulous

A Co-worker mentioned to me this movie called Religulous.  I found it very blasphemous and horrible, so I would not recommend it to anyone!  I probably can’t adequately explain why this movie is wrong, but I’ll try to give my thoughts as best I can.

Bible Study: Malchus’ Ear

This is a quick study for my Sunday School lesson.  I am building up to the Easter story on Easter Sunday.

Story: Peter strikes Malchus with his sword and Jesus heals his ear back

Passage: Luke 22:45-54; Matthew 26:45-56; John 18:1-14; Mark 14:42-50

“Most Important Thing”: Jesus want us to love our enemies

Outline:

  • Jesus goes to the garden to pray knowing his most important task is drawing close
  • A large group of people enter the garden with force
  • Judas leads them to Jesus and kisses him (like a handshake)
  • One disciple asks if they should fight back
  • Peter doesn’t wait for an answer; he draws his sword and begins fighting
  • Peter swipes Malchus’ ear off
  • Jesus said to let them take him
  • Jesus heals Malchus’ ear with a touch
  • Jesus points out that he had been teaching in the temple, and they couldn’t arrest or kill him there.  He is letting them take him: there is no need for force.

Imagining It:

Think of the pain that Malchus must have been in.  I can’t help but think that this must have been a fatal wound.  Could they have stopped the bleeding enough before he lost too much blood?    Was Malchus thinking this was the end?  Then, suddenly he felt the touch of Jesus.  Surely, all eyes were on Jesus since they had come to take him away.  As Jesus placed the ear back in place, all the pain went away.  Malchus was a new man!  Little did he know that just as Jesus healed his ear, Jesus was about to heal his heart’s sin problem by paying his punishment on the cross.

Related verses:

Proverbs 27:6 – Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.

Romans 12:20 – Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.

Matthew 5:44 – But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;

Bible Study: 5 Stories Until Easter

We have 5 Sundays until Easter Sunday, and so, I need 5 stories for Sunday School/AWANA.  I figure I may as well plan this out in the open — maybe someone else will need some story ideas, too.

Easter is an important time for me.  It is a great time to worship God in reflecting on what He has done for us.  At the same time, it is a great way to communicate the salvation plan to the kids.  It was in preparing for Easter story lessons two years ago that my oldest son opened his heart to God and put his faith in Jesus.

February 26th: Demoniac of Gadara

The element of the pigs just makes this a fun story.  At the same time, the story is a stern warning that the demonic world is nothing to play with.  Satan is real, and is a lion waiting to devour.

Bible Location: Mt 8.28-34, Mk 5:1-20, Lk 8:26-39

Key Verse: I Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

March 4th: Raising of Lazarus

A couple weeks ago, we talked about how Jesus could control His creation and stop the wind and the waves.  This story brings it to an even more personal or human level — Jesus controls our life and death.  This story is filled with emotion and potentially funny moments as we have to figure out how to get the burial wrapping off.

Bible Location: Jn 11

March 11th: Triumphal Entry

I think this is a good one to act out.  The kids would enjoy acting out welcoming Jesus to Jerusalem and learning how the Jews “rolled out the red carpet”.  I am realizing, too, that the story of Jesus driving out the money changers comes directly after.  That might be worth including in this story as well.

Bible Location: Mk 11:1-11, Mt 21:1-11, Lk 19:28-44

March 18th: Malchus Ear

This is a fun story.  Of course, Malchus probably didn’t think so at first, but I don’t have to get too gory.  I love hearing the kids laugh, and the idea of an ear sitting on someone’s shoulder leaves plenty of room for that.  Plus, this is a good opportunity to teach the kids the concept of loving your enemy.

Bible Location: Lk 22:45-53

March 25th: Crucifixion Story

Good Friday is the next Friday.  This is the perfect Sunday to talk about Jesus dying on the cross.  Of course, the emphasis for the story is that our sin must be punished, and Jesus took that punishment for us.  Now, if we put our trust in Jesus, our sin no longer needs punishing, thus allowing us to spend eternity in heaven.

Bible Location: Mt 27, Lk 23, Mk 15, Jn 19

April 8th: Easter!  Resurrection Sunday

I have two different illustrations that I enjoy.  Everyone seems to do the Easter eggs with the different parts of the crucifixion and Resurrection story.  Even so, I can have the kids tell the story since they usually can’t wait to say “I’ve heard this before”.  The best one I enjoy is the drawing of an Easter bunny that you can rotate sideways and turn into an open tomb scene.

Speed Test Results

One of the things I wanted when switching to a new host was for my site to load faster.  The hosts all claimed they were faster, and I think I even had one of the Sales people tell me that my site would speed up after I switched.  So, I decided to run some tests and compare …

I tested using WebPageTest.org.  I ran the test before my site moved.  And, I ran the test again today on the new host.  Here are the results…

On the digitaleagle.net homepage:

  • Lunarpages (before): 2.174s
  • Web Hosting Hub (after): 1.229s

On http://psst0101.digitaleagle.net/2011/02/21/step-by-step-peopletools-8-51-upgrade-part-4/

  • Lunarpages: 8.940s
  • Web Hosting Hub: 5.594s

On http://psst0101.digitaleagle.net/2011/12/19/running-jasper-reports-from-java/

  • Lunarpages: 7.589s
  • Web Hosting Hub: 3.804s

So, it looks like my site sped up by a decent amount.  I wish that I could get these kind of stats before I signed up for a web site.

Website Move Complete

Ok, switching Internet Hosting has been a bigger deal than I thought it would be.  Here are a few thoughts that I learned through the process.  Please feel free to add any comments or things you have learned.

Here’s what happened.  I had had a good experience with Lunarpages in the past.  The sales people spoke English well and were very helpful.  So, when I wanted to host my own website, they just made the most sense.  I did the math, it seemed like it would work out, and I went for it.

Now, it’s been a year, and my “contract” is up.  I had an incident with the technical support that left me wondering.  It was probably my fault.  I had used the website to transfer some pictures, and I left both the pictures and some site backups on the site wasting drive space.  The backups were generated using the backup tool on their CPanel, but they sent kind of a threatening email about my using the account for something that I was not allowed to use it for.  When it was all said and done, instead of them simply asking me to delete the files, I began to question how well they knew their system.  They didn’t seem to know about the backup tool and then they said it included database backups when it didn’t!  I ended up writing my own backup tool that included everything instead of relying on their’s.

Couple that experience with finding my admin tool not responding a couple of times, and I decided it was time to move.  We’ll see if that was a good decision, but that brings me to where I am today.

Lesson #1: Choosing a host is hard

I found that there are tons of hosting options out there.  For the most part, they have the same features, but there are slight variations.  Aside from a few expensive ones, most of them were somewhat closely priced.  Sometimes, it was hard to tell that an option was closely priced because everyone had different discounts through different channels.

What I finally did was create a Google Spreadsheet with the different options.  I tried to figure out as much information as I could from each host’s website.  Then, for the ones that looked promising, I went back and chatted with a Salesperson to clarify and ask questions on items that I couldn’t find.  I had one row for each option, and these are the columns that I used:

  • Host name + link to site
  • Sign up link (when I talked to a rep, I wanted to capture their information so that if I signed up they would get credit.  Some had a special link that would give them credit, others just said to mention them in chat or when signing up)
  • Monthly price
  • Total price (my target time frame was a year), including setup fees if applicable
  • Price including SSL (I was unsure if I wanted to pay for private SSL)
  • Promotion link (As you research, you will probably come across links or special codes that give you discounts)
  • Features:
    • Private SSL
    • Script installer (Sure makes installing new applications like WordPress much easier; they come in different names: Fantastico, Softaculous, Script Barn, 1-click installs, etc.)
    • PHP (version 4 or 5, etc.)
    • MySQL database support (version 4 or 5, also watch for quotas in either the number of databases allow or storage limit)
    • Disk space (most were unlimited but not all)
    • Email (quota on email addresses, web interface)
    • Transfer (fee in transferring the domain name?)
    • Java support (usually pretty expensive, and most apps work on PHP)
    • Git support (not many had this, but one did.  Git is handy if you do any development.  You can always compile a binary and upload it to the site, but already having it installed saves some headache.)
    • SSH access (You can always use PHP Shell instead)

Note: You can link to information from a Google Spreadsheet with the hyperink() function.  The format looks something like this:
=hyperlink(“<link URL>”, “<Text to Display>”)

Lesson #2: Reviews are hard to evaluate

I found tons of reviews for hosting all over the web.  The question is which ones can I believe?

First, as I was reviewing the companies, several looked very, very similar.  Finally, I found that Endurance International Group owns a number of hosting sites.   On my list, that included Fat Cow, iPage, Just Host, and Blue Host.  This thread on Web Hosting Talk has a small unofficial list.  These companies all may be great, but when you find a top 10 list of hosts, and they are all part of the same parent company, you begin to wonder about the quality of the review.

After signing up for Web Hosting Hub, one of the technicians accidentally sent me a “How-To” link for another company (I think it was Inmotion).  Come to find out, those two companies are sister companies.  The price and sales may be different between all of these companies, but the support is the same.  So, if you switch from one to the other, don’t expect any different technical support.

One reliable way to find out issues is to look up the Better Business Bureau.  You can see the number of complaints against the company there.  I don’t know how many people actually go to the Better Business Bureau or do they complain in forums and such.  So, forums may be a better place to look.

Lesson #3: Plan Ahead

Your current host will probably automatically renew your domain name and your hosting.  Lunarpages sent me a reminder/warning that they were going to renew, but I think you should be at least starting to plan what to do a month before your service is up.  Here’s what you have to allow time for:

  • Give your current host notice that you are not continuing
  • Research time to pick your new host
  • Time for migrating your pages, applications, databases, etc to the new host
  • Transferring the domain name: there are waiting periods for the host to transfer, plus multiple companies and steps involved

All in all, you should probably allow a month of overlap between the two contracts.

Lesson #4: Monitor Better

When on Lunarpages, I had a couple of issues where I visited my site, and the database was unreachable or the site wouldn’t load.  It was intermittant, and I never could nail down any exact problems.

I ran across this service: pingdom.  Please comment if you know of other methods to monitor.  Then, if I have issues, I know how bad they are and have concrete proof.

Lesson #5: SSL is Expensive

I still haven’t found a definite solution to SSL.  The issue is that using any kind of site that requires a password is insecure if you don’t have an https page.  The biggest danger is if you access your site using your password on a public network: restaurant, airport, library, etc.

The issue is that to do SSL, you have to have a dedicated IP address.  Then, you have to pay for a certificate.  Price it out, and I think you will find that this might just double your cost.

The two options that I need to research are shared SSL and Start SSL.  The problem with shared SSL is that you can’t use your domain name to access your site.  So, I have to figure out how to configure WordPress to work with that.  Start SSL claims that they will give you a free certificate, but Web Hosting Hub told me that it would cost $25 to install the certificate.

I have tried looking into different encryption schemes and Open ID to at least prevent sniffing passwords, but I keep coming back to the same thing.  There is no alternative to SSL.
