Serious setbacks today.

I tried giving my Intel Create and Share camera another try with the drivers over at http://sourceforge.net/projects/spca50x/ and gqcam http://cse.unl.edu/~cluening/gqcam/ in the hopes that I could clearly identify the functionality to write up exactly what wasn’t working and send it into the mailing list. Unfortunately after it ran for a bit and poked at a few options and then suddenly the machine crashed… Oops!

So after it rebooted I decided that maybe I shouldn’t be playing around with highly experimental drivers.

Next up, wireless drivers under Windows XP. I found the Proxim RangeLAN-DS drivers for XP on their web site. Unfortunately while they installed smoothly and the drivers seemed to work OK, but I couldn’t get it to DHCP off the WAP. I tried all the settings suggested in the README. The "open mode" found the AP, but couldn’t DHCP. When running in "shared key" mode it couldn’t find the AP. And the weird thing was that the "eject devices" stuff didn’t ever show the card.

So, then it was time to retry the Lucent Orinoco card again. I stuck it in to and tried to uninstall the default driver that came with XP in the hopes that replacing it with the Lucent driver to try and prevent the card from blue screening XP (Yes, I managed to BSOD XP using only the code provided on the hard drive). It BSODed when I tried to uninstall the driver, but it must of worked since I reinstalled the Lucent stuff it appeared as the driver when I plugged in the card. Unfortunately, less than a minute in, it BSODed again. I even tried using my other Lucent card with more reboots.

Seems like it’s time to by a D-Link or a Linksys. I know people have used them sucessfully with the IBM WinXP laptops.

I’m almost afraid to try getting my Zaurus to work with the Linux box. Too many things going wrong tonight…

More fun with the Oracle. My response to this one isn’t too bad.

< Oracle Most Wise; < < What affect, if any, will The End of The World have on The < Stock Market?

Now you might think that The End of The World ™ would have a negative affect on the stock market, considering that most economists believe that the price of stocks are related to companies future earnings potential, and that the destruction of the world, and thereby presumably all money stored on said world would significantly reduce earnings potential for basically all companies.

But this isn’t actually the case. The value of stocks are determined by an old man living on a shack on the moon. He selects values for the stocks based on the number of steps he has to take from his shack to the nearest selection of his favorite cheese (yes, the moon is made of cheese, but not all of it is really edible). So small changes in the market are generally attributable to him having to travel further as he eats nearby selections of cheese. Larger changes are usually caused by him switching from cheddar to gouda.

Now you probablby have doubts about the veracity of this, but consider this: why else do governments build huge telescopes? It’s to spy on him and track the availability of various types of cheese around his small shack. The Wealth Of Nations is not found in gold, but on the moon.

You owe the oracle a large telescope and a map of the moon.

Quite possibly one of the coolest projects I’ve ever seen implemented. This guy put together a remote controlled blimp along with color quickcam and a chunk of software to create an automated blimp-courier. Way cool stuff for cubeland.

http://www.hpl.hp.com/shl/projects/blimp/

It’s got some limitations, but the concept is brilliant, outside the box thinking, and the implementation is fairly well thought out. Although the implementation is more of a prototype than a working model. I’m really impressed :-)

So news broke yesterday that Sharp is introducing the SL-5600 Linux-based PDA, and slashed SL-5500 prices and are dumping them on HSN of all places for less than $200. The idea of a built-in thumbboard and linux installed on it had always been appealing, so I broke down and ordered one.

Bible study went well this evening, but found out that James is out next week so I get to do the rest of Acts 4. It’s going to be a little tricky…

So James and I are playing ‘Trading Spaces’ at Bible study this week, so I get to do the study part on Acts 4:13-22.

Background: Peter and James were going to the temple to pray, but they met a lame man at the gate and Peter healed him in Jesus name. Many people were amazed by this, and so Peter and James started preaching Jesus to the people. Priests and Sadducees saw this and arrested Peter and James and the next day brought them out and asked them ‘in what name have you done this’. Peter is filled by the Holy Spirit and starts preaching again, and has just finished up in verse 12, which is where we pick up the story…

Read Acts 4:13-22

13-14:

Peter and James were seen as:

  1. Confident 2. Uneducated (not religiously trained) – Mark 1:16-19, Luke 5:1-11, John 1:40 3. Had been with Jesus 4. Had clearly performed an undeniable miracle – the ex-lame man was there,

System Message: WARNING/2 (<string>, line 14)

Enumerated list ends without a blank line; unexpected unindent.

and everybody knew him, and had walked by him for nearly 40 years.

Peter and James were just ordinary people until they got connected with Jesus and had a personal relationship with him. Now, the top dogs of the day are starting to realize that these guys have religious knowledge, demonstrated spiritual power and leadership. And this is potentially a threat to their position as the spiritual leaders.

15-18:

The debate and response of the religious leaders:

They get to just their group to confer (see also Matthew 21:25)

  1. They acknowledge that a miracle has occured 2. But they don’t ask what it means for them personally, or even

System Message: WARNING/2 (<string>, line 25)

Enumerated list ends without a blank line; unexpected unindent.

‘professionally’ 3. They aren’t interested in giving God credit or even Peter and James
credit for being the instruments of God for the miracle. Why? Because
they were more interested in their position than in seeing God glorified. 4. So they plan to try and keep Peter and John from preaching since they
can’t deny the miracle.

Things haven’t changed a bit since Jesus was walking the earth. Look at John 11:45-54. They treat his disciples the same way. There will be people who will treat Christians today in the same way.

19-20:

Obey God or Men:

They pose it as a question to limit their ability to answer directly. As the religious leadership, the Sanhedrin can’t say that Peter and John should obey men instead of God. This passage is important in that Peter makes it clear that authority, civil or spiritual comes from God, and that he and James will follow God’s authority as given to them, instead of the authority of the civil/spiritual leaders of the Sanhedrin.

This is not an abandonment of civil government. Jesus taught his deciples to pay taxes (‘render unto Ceaser what is Ceaser’s’) and Paul writes in length in Romans 13:1-7 about the importance of obeying the local government.

21:

The religious officials threaten Peter and John again, but then release them because they can’t charge them with anything — Galations 5:22-23. And also the people were watching the proceedings, so the Sanhedren can’t punish them for no good reason without appearing to be unjust, and thus degrading their public opinion.

Here’s the sad point. Once again, the religious leaders of the day have missed seeing the glory of God, but many people around them saw the miracle and were praising God for it. How often do we overlook miracles or other ‘simple’ acts of God instead of praising him for his works and his majesty.

22:

Even more information that Doctor Luke provides about the lame man, possibly to further clairify that this miracle was a truly supernatural event, since it could not be attributed to a boy growing out of his weakness, and it might also be to better identify the person in question to Theophilus, who might have even walked by the lame man at one point.

In terms of computing I think I’ve learned a few things recently:

First, always make recent backups — hard drives aren’t as reliable as you may have been lead to believe. I lost my primary drive in my Linux box back in December. The one with all my digital photos, plan files, html files, CVS repositories, server config files, all that good stuff. Fortunately, some of the really important stuff I had copies sitting on my laptop, but there was a pretty darn good chunk of data that only existed on that drive, and possibly cached across the net.

If I had really had my wits about me, I would have dived into google’s cache right away. Fortunately I found the internet wayback machine http://web.archive.org/collections/web.html and was able to retrieve about 80% of my plan files from before the middle of last year.

I also took the hard drive and after detaching the existing disk and burning a linux "SuperRescue" CD got the drive to the point where it is mountable, but there are a ton of errors on it still. So I’m using scp to try and copy off what data will come off the drive and save what I can back onto pooh over the network. I’m thinking that the drive is probably just plain toast, but I’m managing to get some good data off of it from the old /public area. I tried accessing the home directories, but they appear to be a lost cause, which is really sad, since that is where a lot of the really useful data was stored. I’ve also got some older CD backups that I’ll need to mesh together with what I can recover from the drive and other sources.

On the plus side, upgrading to RH8.0 has been a fairly positive experience except for some PHP incompatibilities with both Gallery and Bookmarker. And thanks to grip and mserve (utilities to serve .mp3 files to my Rio Reciever) I’ve got my Rio sitting on top of my TV and playing lots of fun audio files over my home stereo system. I do think that I understand better why the Rio didn’t sell so well. The user interface on the box is really, really bad. So over the past week or two I’ve been putting CDs in my box and grip rips and encodes them using lame and then spits them back out. I’ve managed to get probably over 60 disks done so far without a lot of hassles. I do have a couple that may be a bit of a problem getting info on them through the freedb servers, but currently I’m almost suspecting a problem on their end.

A somewhat amusing response for the Oracle this time.

&lt; Oh wise Oracle most effulgent and sheltering, &lt; &lt; Have you heard anything about a new hog flavored book?

Sounds like hogwash to me.

But seriously, there’s been a resurgence in alternatives to making books out of paper. Let’s take a look at a few of the possibilities including your idea of using animals:

Pork – Bacon specifically, since that’s usually the flattest form of hogs.
Binding bacon into a book could prove to be a little tricky, and printing
onto bacon, cooked or uncooked is pretty tricky. On the plus side, you
can even eat it for breakfast.
Plastic – It’s much easier to print on than pork, and has some nice
qualities like being waterproof so you can read it in the bath. But
plastic is just processed petrochemicals, so technically you are
reading an oil-slick. That’s got to be a little weird…
Metal – While metal has been used for a few books (Ancient Egypt’s
book of the dead). It tends to be a bit heavy and certainly not the
kind of book that you can take with you into the bath. And anything
over a couple of dozen pages is a tome with too much weight to
carry anywhere without a camel.
Cloth – Cloth has been used from time to time as book material. It can
be a little floppy and hard to use without a table of other flat
surface. On the plus side, you can make trendy clothes from various
books. Think of a shirt by Ann Rand, pants by Marvel Comics.
People – Making books out of people is generally frowned upon in most
civilized societies. But there are a few books, most notable the
infamous Necronomicon. Of course such books are carefully guarded,
just don’t pick up the wrong book.

You owe the Oracle a book on how to make Solyent Green

Another Oracle answer. This one isn’t all that good though.

&lt; I owe you a left-handed toothbrush. Where can I &lt; find one? The folks at Wal-Mart laughed at me, &lt; and told me I’d find it in the paint department &lt; right next to the striped paint. They were wrong.

Listen more carefully, I said leaf-handled, not left-handed. And looking for anything in Wal-Mart is never a good idea. That little yellow smiley face is just a facad for one for one of the most dangerous creatures besides the clown in Stephen King’s "It". So for starters, stay away from Wal-Mart, especially after dark.

Anyway, back to the leaf-handled toothbrush. If you had paid attention to your teacher Mrs. Grainsworthy in your 9th grade geography class you might have remembered that in the South American rainforests the natives of that land don’t exactly have the latest in consumer items, so they live off the land and so for keeping proper dental hygine they brush their teeth using branches and leaves. The really good toothbrushes are made by a shamen name is Gri’es Zoram. While you are there would you pick up a jar of bubble-free bubble bath? Thanks.

You owe the Oracle a leaf-handled toothbrush and a jar of bubble-free bubble bath.

So I was thinking of purchasing a new scanner to scan in photos that we gotten from various people of the wedding and stuff like that. I figured it would be nice to get a scanner that was supported under Linux. In general I’ve found that linux-supported stuff tends to be slightly higher quality, and usually there are more of them so it’s less likely that I’m buying some hunk-o’-junk without realizing it. I had picked out a Epson 1260 scanner, which was on sale at CompUSA for a rather nice price with a $30 rebate as well. But when visiting with my parents on Saturday for Mom’s birthday, they told me that they weren’t using the scanner I’d loaned to Mom for use at the Church.

So I got that scanner back (after a year or so of it being over at their place unused), and then went online to the sane home page to see if it was supported under linux. Sure enough, it was there, an Agfa SnapScan1212u. Unfortunately, what wasn’t obvious is that I needed to get the firmware binary into a known place so that the software could load the necessary firmware into the scanner before it would work correctly. Fortunately, a couple of websites later I had it mostly figured out (thanks largely to http://hem.fyristorg.com/henrikj/snapscan/) and copied the correct file, SnapScan1212U_2.bin file from the driver CD into the /etc/sane.d directory and then edited /etc/sane.d/snapscan.conf to point to the .bin file (also removed the space in the filename). After that, xsane worked, but only appears to be able to save raw RGB files, so I switched to gimp, and then use the ‘acquire’ menu to invoke sane. That works out pretty well.

The scanner quality is reasonably good. I only does 600×600, but for scanning in photos it appears to be plenty good enough, and the files that it generates off a 4×5 photograph are pretty huge, around 800K a pop in .jpg format. It’s probably overkill, but I’m not sure how worried I should be about it. As long as general sections still fit on CD, it’s all good.

Next I need to figure out a good way of ripping and encoding CDs :-)

I’ve been thinking a lot about the church website recently. Mulling it over in my head, looking at various other sites and site-building tools and thinking about the overall design goals and purpose of the website. The key to a good website (or any communication tool) is to understand your goals and your audience. Once you understand those two, you can use tools (websites, verbal speech, written documents, etc.) to achieve your goals. I’ve attempted to condense my thoughts together and summarize them in a meaningful way. You could say that the goal of this document is to enable me organize my thoughts, ideas and research into a single place.

The church website is currently only focused outward. It contains some limited information about the church that would be helpful to non-members, and more specifically, people who have not attended the church before, but already have some church background. I feel that there are some particularly strong points to the current design and content.

1. Provides basic theological beliefs. Useful for people looking for a
church who already have some church background

2. Provides contact information and directions on how to get to
the church

  1. Overview of ministries, but nothing specific
  2. Overview of Sunday services and times, but again, nothing specific

I’d like to suggest that the website can be a much more useful tool for the church in a couple of areas. First, it can be reshaped into a communication tool for the members as well as non-members. Second, it can be developed to provide more useful information to unchurched people. Third, it can grow into an organizational tool for the staff.

There is one issue that often comes up, and that is that not all church members have access to the web, and we don’t want to create a "digital divide" within the church. This is certainly a valid concern. I believe that the key to avoiding such a problem is to ensure that the website mirrors and complements our printed material, instead of attempting to replace it. This is an issue that those who update and support the website will need to keep in mind on a regular basis. Also we can set up one or more systems at the church that could be used to view the church’s website exclusively (making it difficult to abuse). Even very low end systems could be used to do this with minimal cost and effort.

Reshaping the website to be a communication tool with the existing members about church events, news and messages will likely require some substantial restructuring since it changes the primary focus of the site. Also, it requires that people (most likely the staff) add content to the site on a regular basis (I’m thinking 10-20 pieces of information each week to be effective). The key to the site being useful is that it contains up to date information on events, news and messages from the church. Getting this information on the site can be partially automated and made part of the normal flow of work for the staff. I’ll attempt to go more into detail on this later on.

Consider the different kinds of printed material that the church produces on a regular basis, the Sunday and Saturday night programs, the newsletter, announcement letters to groups of people. I think they contain information that can be classified into a couple of categories:

1. Events – Usually upcoming with information about when, where, who,
what and occasionally even why. Also, there is sometimes event
summaries, like when we had the Mexico Mission trip people come back
and show photos of what they were working on and what happened.
These might be classified as news.

Examples of events: Most of the middle sheets in the program, the
calendar in the newsletter, letters sent out to parents of youth
about an upcoming outing. The order of events and the sermon title in
the Sunday morning program.

2. News – Information that isn’t usually tied to an event that people
would likely participate in, and may or may not require any
particular action by the reader.

Examples of news: Family Matters, giving information in the program,
a change in who is on the trustees committee, a request for help in
the nursery on Saturday nights, an update letter from missionaries.

3. Messages – Communication not regarding any particular event. Usually
intended to educate or encourage.

Examples: Pastor’s column on the back of the program, sermons, an
article in the newsletter about how to raise Godly children, the
article about why the elders believe that it’s OK for women to be
ministers. A page describing the purpose of the house and grounds
ministry, or the meaning of worship.

Naturally there are sub-categories to each of these, but I believe that most of the communication of the church can be put into these three broad categories, and that the properties of the information in each of the categories is unique to the category, and the distinctions useful for enabling a discussion of the categories as distinct entities instead of discussing the information at a finer granularity.

As a quick aside, orthogonal to categories like Events, News and Messages there are ‘topics’ like "youth", "missions", "music" that we can group information into to allow people to more easily focus on their interests. For example, I don’t have youth or children, so I generally only skim over any announcements involving youth and children. To enable efficient communication, a mechanism for easily filtering out or highlighting topics of interest would be highly desirable.

Let’s now take a quick look at an implementation of news site to give our imaginations a bit of a kick-start on how other people have organized similar information. The first is http://slashdot.org/ one of the largest ‘geek’ news websites. It’s a pretty busy layout with a lot of information, but down the middle you see the most recent news stories in chronological order, but just the summaries. Clicking on the ‘read more’ link of a story reveals the rest of the story (assuming there is one) and also comments submitted by other readers. Along the sides are boxes with links to other areas of the site including pages that are built with just specific information from a category or a topic (just book reviews, or articles on the topic of space for example). Also, frequent users of the site can set up filters so that they see (or don’t see) particular topics or categories of articles on the site more easily.

Also of interest to us is the behind the scenes activities that go into supporting the site. To do this we need to have some insight into the lifespan of a ‘story’ in the slashdot site. To summarize:

  1. A user (could be anyone) submits a story

System Message: WARNING/2 (<string>, line 73)

Enumerated list ends without a blank line; unexpected unindent.

2. A site author (restricted to trusted people) edits the story,
assigns it to a category and a topic, and the releases it
3. The story now appears on the front page of the site for a time, it
can now also be commented on by other readers of the site
4. As the story ages, it gets displaced from the front page by newer
stories and moved to the ‘recent news’ section where only the
title appears
5. After getting displaced from ‘recent news’ it can still be
found through the search engine, or other links that people set
up manually.
6. After a specified period of time, new comments are not allowed and
the story is ‘archived’ meaning that all the information is kept,
but no new comments can be made to the story.

The slashdot site does an excellent job of handling News items, but in other areas of interest for us, Events and Messages it doesn’t do as well, since it wasn’t designed to support those categories of information. I think that Messages can be handled in a similar manner to News, but we need to archive them differently than News since the usefulness of Messages is not as limited in time as News items are. A Message may be useful and important for many years, where a News item may only hold vague historical significance after a month or even week.

Events are a more rich data type. They contain not only basic text like News or Messages interspersed with possibly a few images, but information about a date, time and location that users will want to search or sort based on those values, so they must be made explicit to the underlying software to enable such searching and ordering. For example, providing a list of events in the order that they were submitted to the system isn’t particularly useful to the users. At a minimum they want to seem them in the order that they will (or did) occur, and preferably in a format that they are familiar with, like a month view with the events inserted on the correct days or perhaps a week view. This was already attempted on the current website, but because it is usually not up to date with reality, it isn’t useful to people.

Events have a dual nature. First they inform people of an upcoming event, and after the event is past, they can inform people of what happened at the event. By modifying the flow of a story in Slashdot to include multiple editing steps to add information (like pictures, additional text, lists of people in attendance, etc.) the dual nature of Events should be supportable, and the creation of an alternative view (a calendar view) would provide a clear and recognizable interface for users to navigate.

So we still haven’t addressed the fundamental issue of how to provide current, regular updates of information to the website. If the website isn’t kept up to date with a sizable amount of useful content, it won’t be useful. It’s a kind of ‘critical mass’ problem. I believe that the key to keeping the content up to date is to make it part of the normal working behavior of the people generating the content, which is usually the staff. And the key to enabling the staff to get the content on the website is to integrate it as part of their normal working behavior. This is probably the most difficult problem to solve for any website.

Let’s take one example of how this might work (Note: I’m making some big assumptions about how the staff and office works. A more careful analysis should be made before implementing anything).

Each week James writes a column for the back of the program. He writes
it in his favorite editor (probably MS Word) and then emails it to
Laurie to be included in the Sunday morning program. She cut-n’-pastes
it into the space reserved on the back of the program, cleans up the
layout and fonts and then prints the program which people read and
then recycle.

Now let’s change the flow just a little:

James writes the program in his favorite editor (most editors should
work) then uploads or exports the text to a web form, fills in a few
fields like Category and Topic and publishes it on the web. He then
emails the link to Laurie who cut-n’-pastes the text from the web into
the program and does the formatting and printing…

By inserting a fairly minor change, we got the information on the web where it is now visible by a wider audience (people who missed the service, lost their program, or maybe haven’t ever been to our church), it could be commented on by readers more easily (if we want that feature) and it is archived in a known, searchable location which can be useful for both members and staff to use for reference (e.g. Do you remember James’ column from last month about caring for others?).

So the basic theory is that most of this stuff needs to be typed into a computer anyway. By doing a very small amount of additional (or more structured or specific) work, it can be then transformed by programs to be externally visible and archived, leveraging the existing work for larger benefits.

So I’ve talked a lot about providing up to date information that will make the site more useful for members, how to organize that information and how to get the content to the site as part of existing workflows. There are other usage models for the website that I believe are worthy of attention, but would inherently be helped by solutions in this first area.

Making the website more useful for the unchurched is an area that I think the current site isn’t particularly good at. Most of the information is really more oriented at someone who knows who Jesus is and what a Church service is like. Also the information is rarely specific about what we do and what we care about. Now if we start implementing something like the ‘Events, News and Messages’ concept above, we can create a section of Messages that talk about what Christianity is about, what the Church is for, and similar topics. A visitor to the site could also start to get a feel for the Church activities by looking at the Events and what the Church cares about by looking at the News articles.

Basically, if done well, we expose the activities, concerns, dialog, and inner workings of the Church to the rest of the world for them to see what we are all about. If we are who we claim to be, they should see Jesus by seeing who we are and what we do.

The website can also be a useful tool for the staff by providing a framework for organizing and archiving information. Clearly the church needs a unified calendar for keeping track of all the major activities from all the ministries. Currently it’s kept on a giant poster in the office. But if that calendar was moved online, it would be easier to maintain, and also easier to take places (just print a copy, or connect to the website).

Additional tools could be developed to reserve resources to help ensure that the vans or rooms in the church aren’t double-booked. Or attach attendance lists to Events (but hide them from non-staff website viewers) to better track who is showing up to various activities. The idea is that if you can think of something that you want to track or automate, it is likely it can be integrated into this process to help you spend less time in the office and more time out in the field working with people.

As an archive tool, such a website could be very valuable for looking up information on various previous events since they would be archived. For example you could check the sermon title, or list of songs from the previous year’s Easter service to remember things that worked, or didn’t work. Uploading photos and attaching them to events could provide a searchable repository of digital photos with wide-ranging uses.

I’ve discussed a lot of wide-ranging uses and suggested some fairly major changes to the status quo. What we also need to keep in mind is how changes like this will help people grow closer to God, and at what cost. If there are other activities that will help more at lower cost, then we should pursue those opportunities instead of going down these paths.

Some example sites (of style and structure, not content)

http://www.slashdot.org/ — example of a very dynamic and well-organized story-based news site.

http://www.lottadot.com/calleria.pl?month=1&year=2003&#167;ion= — An example of a calendar built as an addon to slash.

http://www.wildfaith.org/ — slash-based site for "peace" with great graphic design and a more static layout than most slash sites. Their events page appears messy and poorly laid out.
