Update on WYSIWYM editor
by Emily Clarke 30 Nov '06

30 Nov '06

You may have noticed that the WYSIWYM editor is not working properly. There is a dependency for the HTML to Wiki converter that hasn't yet been met. The problem appears that the converter will not build under FreeBSD, the OS on the AMSAT server. So although it works on my staging server (running Fedora Core) it will take some additional work to get it working in EaglePedia. 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Improving your ability to search in EaglePedia
by Emily Clarke 28 Nov '06

28 Nov '06

When you search inside EaglePedia you will generally find articles you are looking for. However, if you are looking for information about an EaglePedia user or a help topic you probably aren't getting the results you need. This is because by default EaglePedia searches for articles in the Main namespace. What is the Main namespace, you ask? The core structure of EaglePedia is organized into "super-categories" called Namespaces. You can find a list of these by clicking on "my preferences" in the TOP RIGHT links on every EaglePedia page, and then clicking on the "Search" tab. By default these will generally only have "(Main)" checked. I would recommend at a minimum you check the following Namespaces: Talk User Help Image Category 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Category Required (was Re: Orphaned and uncategorized files and articles in EaglePedia)
by Emily Clarke 28 Nov '06

28 Nov '06

Hi Stephen, Part of the upgrade was to install an Extension to the core MediaWiki software that does not allow you to save an orphan pages. Whenever you edit a page this extension checks to make sure that there is at least one [[Category:something]] reference. The NOTICE is pretty much the instruction - simply add in the category as shown in the NOTICE and substitute the appropriate Eagle category for "something". You can then save it. I have discovered one problem with the "Category Required" Extension. If you are editing a section (the edit link to the right of a section header) it still checks for a category. I think this is punitive, so I have contacted the "category required" extension author. The work around is to either edit an entire page or duplicate the category reference in the main article. 73, Emily At 08:29 PM 11/27/2006, you wrote: >Emily, > > Going slightly nuts am I? > > Every time I edit an existing page (attempting to correct missing > file links, etc.) I get a: > > "NOTICE: There must be at least one [[Category:something]] link." > And no save!

Thanks for reporting this Steve. It was a definite bug (un-initialized variable.)

Orphaned and uncategorized files and articles in EaglePedia
by Emily Clarke 27 Nov '06

27 Nov '06

Since the upgrade, I made a big effort to improve the navigation in EaglePedia and now that the coding changes are completed spent some time going through EaglePedia to see how well things have improved. The answer is that it is still difficult to locate articles and files in EaglePedia - mostly because things are unused or uncategorized. It would be very helpful if the uploaders/article authors could review the list of unused and uncategorized files and add categories and link them into an article (even if that article is just a short summary.) An unused file is a file that has been uploaded and hasn't been linked into an article. For true images (JPEG, GIF or PNG) this means there is no article that contains the embedding reference (for example) [[Image:MyImage.jpg]] to display it. For non-image files (PDF or DOC) this means there is no article that references it using (for example) [[Media:MySpecification.pdf]] You can find a list of unused files (and the name of the user who uploaded it) here: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Special:Unusedima… Files should also be categorized when uploaded. This means that when the file is uploaded you should add the category it falls into. This which should normally be the same category as the article that will reference or embed it. Before you upload a file you should probably browse the project categories (now shown on the front page of EaglePedia) and locate the appropriate category. When you are at the file upload screen add the category into the summary by typing in [[Category:This Category]] To see a list of uncategorized files go to: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Special:Uncategor… To categorize a file that is already uploaded without uploading another copy click on the "Edit" tab at the top of the description page, and then add the category information as shown above. Thanks in advance! 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

EaglePedia Upgrades
by Emily Clarke 15 Nov '06

15 Nov '06

EaglePedia is online and most everything is working. The exception to this is that the WYSIWYM editor doesn't work. One of the dependencies (a perl routine) has not been installed. It should be shortly, but if you try to use that functionality you will receive an error that basically says a required module is not installed. Everything else is working - I encourage everyone to read the online release notes: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/EaglePedia_1.1_re… This should explain the upgrade. 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Re: Solar Power Systems -- White Paper FYI
by Paul L Rinaldo 13 Nov '06

Tom, We've been watching this subject for some time in ITU-R Study Group 1 (spectrum management). As I'll be traveling this week, I've asked Jon Siverling to review the relevant ITU documents and advise. Paul At 01:59 AM 11/11/2006 -0500, Tom Clark, K3IO wrote: >>>> I am a member of URSI (International Scientific Radio Union) Commission J (Radio Astronomy). The US National Committee of URSI has asked its members to review the attached document on Orbiting Solar Power Stations. I send it along to you for information. You will see that the concepts might involve Microwave Power transmission at S-Band (2.45 GHz) and/or C-band (5.8 GHz). In the main footprint of the beam, the power flux density might reach (near fatal!) levels of ~300W/m. The orbiting antenna will certainly have sidelobes likely would wipe out many services. You will note comments indicating that that this worries many radio astronomers who routinely make measurements as sources with flux densities of 1 mJy (1 Jansky =s a power flux density of 1x10e-26 w/(mHz) . In the event of a failure of just one active element, the beam-forming properties of the orbiting antenna would certainly degrade. Inside the report you will note a statement that even with a MTBF of ~30 years for magnetrons, this implies a failure of one element/day for the array! It is interesting to note that the report indicates current launch costs of ~$10,000/kg (this is about the going rate for a Dnepr launch to LEO), decreasing significantly by 2025 (good news for us, if true). It is also interesting to note that the report still indicates the use of (relatively) low efficiency solar cells and doesn't even note the ~28% cells that we have been using. I have no idea of the reality of these systems. I presume that AMSAT/ARRL/IARU could make comments to URSI. The following is the "charge" given to URSI members which calls for responses a scan 1 weeks hence: <fontfamily><param>Helvetica,</param>Dear USNC-URSI Colleagues: The past president of URSI, Professor Kristian Schlegel, has asked me for the USNC opinion on the proposed URSI white paper on solar power, copy of which is attached. Even though it appears that the conclusion is foregone because a majority of URSI member countries are in favor of the proposal, it is important that the US opinion be registered and our objections, if any, be forwarded to URSI and remain a matter of record. I am therefore asking that you let me have your reactions by e-mail on or before Monday, November 20. I will collate them into a memorandum that I will send to Prof. Schlegel by his deadline of November 22. It is especially important that I hear from the Commission Chairs, and crucial that I receive the opinion of Commission J. I apologize for the short notice. I was hoping that we could discuss this matter at the USNC business meeting in Ottawa next summer, but it now appears that URSI is in a hurry to decide the issue soon, and is not willing to wait. Best regards, George Uslenghi Chair of USNC-URSI. _________________________________________ Piergiorgio L. E. Uslenghi, Ph.D. Professor and Associate Dean Department of ECE, College of Engineering University of Illinois at Chicago 851 South Morgan Street, Chicago, IL 60607, USA</fontfamily> Dave Woodie (CalTech), the current USNC Commission J chairman, appended these notes from last January's submission by the Radio Astronomers: <fontfamily><param>Helvetica,</param>Discussion of the solar satellite white paper: Commission J members are concerned about the process for producing such a white paper and whether there is an implied approval by each commission. Many of the issues with this project are beyond the technical scope of the URSI commissions and hence it is inappropriate for URSI to take a strong position on this project. Individual commission J members expressed strong reservations about this project and do not want to be associated with a white paper supporting solar satellites for beam power to earth. (The commission J chair, David Woody, expressed these concerns to the URSI executives during the Saturday morning executive session.)</fontfamily> Comments? 73, Tom Attachment Converted: "c:\eudora\attach\URSI white paper on solar power.doc"
