My neighbor was going to pour some cement into the trough (a depression in the roof about 2 meters in diameter) and paint over it, but I suggested that maybe we should go a little further. I hate doing things twice. My father was here visiting and what better way to spend your vacation than helping your son repair his roof?

We started by cleaning the affected area, removing the old paint and vacuming out the dust and other junk that had accumulated between the tiles over the years.

We then applied a “resin” (not sure of the chemical makeup) to help the cement stick and minimize leaking. When the resin dries, it leaves behind a sticky substance not unlike the glue on the back of some price tags (that is impossible to remove).

The hole we were trying to fill was about 1.5cm deep (about half an inch). Note that we only measured one dimension. More on why later…

I had never poured cement before but my father had, so with his help, we managed to pour a fairly nice patch filling the hole. We used an entire 20 kilo bag of cement (well, 85% of the bag) and were very careful not to let the cement get too wet. The cement dried in a few hours (it was hot and sunny) but we dampened it to keep it from cracking and by the next day, it was ready to be painted.

The paint, known as sealent here, seemed to be a “rubberized” acrylic paint with some insulating properties. It is a bit disturbing to think that this is the ONLY thing keeping water from penetrating the tiles, mortar, and cement below. Shouldn’t there be some sort of rubberized layer (at least 1/4 inch thick) glued to the surface with some petroleum based product? Apparently, this paint-only approach is standard here in the islands.

Two coats (and 24 hours) later, the job was done, and just in time too. It started to rain about 8 hours later. Unfortunately, for all of my good intentions, it looks like this work was mostly for naught. As I stated above, we only measured the depth to fill by one dimension. This is because the neighbor was convinced the water was leaking through where it was accumulating. I, however, suspected that filling that one hole would simply push the water to other parts of the greater depression, which is in fact what happened. Thus, to really fix the problem, we’re probably going to have to fill nearly the entire roof with about 2cm of mortar.

http://tedmasterweb.com/php-bbedit-clipping-set/

HIGHLIGHT: The new set contains more than 9,200 clippings (that’s about 3,000 more than the previous version).

Changes in this version

• all clippings (optionally) conform as closely as possible to the Zend/PEAR style guides

• removed hundreds of duplicate clippings (mostly constants)

• removed “cruft” (primarily from Snippets and Control Structures)

• reorganized clippings into more logical folder structures

• based this set on a very recent version of the manual

• the set now includes more than 9,200 functions, constants, methods, properties, snippets, control structures and more

• added additional “interactive” functionality to some date functions (I could never remember exactly which switches to use when formatting dates)

• the set now includes class methods and properties

• renamed the clipping set to just “PHP.php” (except for the “Loose” version, see page for details)

I don’t believe 1% of what I hear so I decided to research these claims. While researching I stumbled on Spyfu which offers a list of the most expensive keywords being used in AdWords. The astute reader familiar with Google’s AdWords and AdSense programs will immediately recognize the arbitrage opportunity.

Living in a vacation paradise, having a large selection of potential “stock” photos, knowing something about SEO, and having just received a gift certificate for 50€ in AdWords, I decided to try a little experiment. According to Spyfu.com, “hotels”, “travel”, “flights”, “rental”, “vacations”, “holidays” are among the higher paying keywords that one would associate with my collection of stock photos.

The goal is/was to spend (invest) the 50€ on AdWords at rates lower than what other advertisers are paying to have their ads appear on my site, and then hope that users either buy a license for my photographs or click on an advertisement. This is classic “arbitrage” but avoids breaking Google’s AdSense guidelines because the primary goal is to sell licenses and give users some pretty pictures to look at.

I set up a “stock photography” subsite on tedmasterweb.com with lots of pictures of landscapes here in the islands, in other parts of Europe and one of my dad’s farm outside Chicago. Nothing complicated, but fine tuned for SEO, ease of use, and directed at potential stock photo buyers or anyone who likes to look at pretty pictures of places they are going to visit.

At first the ads appearing on the site were all for financial-related things (like masters degrees and stock trading systems). I changed the subdirectory from “stock” to “stock-photography” and the ads, thankfully, changed to reflect more travel and graphic arts related offers. I also added a AdSense placement on the landing page (rather than just on the enlargement pages). These two changes improved my “conversions”. In just a couple of days I had 3 clicks on ads (whereas prior to the 50€ I went months without a single click!). This great article on another AdSense Arbitrage Experiment corroborates my findings (money can be made, but you’re likely going to lose at first).

In the end, as you might have guessed if you have any experience at all in this field, the experiment proved what any reasonable person would assume: My ROI on this so far is a loss of 48€ (plus the several hours I put in to setting everything up, which I could have billed at 70€/hour for any of my clients).

The next step, of course, will be to improve the quality of the textual content on each page so that it targets holiday travelers more directly and gets them to link to these pictures (and ultimately click on the ads too) and to target my keywords better (so that only very interested people click on my site). I’ll post an update at some point so stay tuned!

But before I go…

I also signed up for Google’s AdSense for domains since I had several domains I’d purchased as part of this same experiment (but a more developed version of it). We’ll see if this provides any additional income. Here are the domains in case you’re curious:

1. Stock holiday pictures (without hyphens)
2. Stock holiday photographs
3. Stock photography royalty free
4. Stock vacation pictures (without hyphens)
5. Stock vacation photographs

We’ll see how all this turns out, but the next time someone tells you they’re bringing in 4,000€/month in AdSense income, tell them you want to see their AdSense account before you’ll believe it.

Tired of producing mediocre code and eager to learn what this whole .Net thing was all about, I decided to invest some time learning how to write better ASP and take advantage of as many features of .Net as I could. Armed with two really good books on the subject (Beginning ASP.NET 3.5 in C# and VB and Programming ASP.NET 3.5, 4th Edition), I learned a lot about the .Net revolution and in the end I significantly improved the quality of my code.

.Net borrows heavily from other MVC-like frameworks. I was surprised by the number of similarities between the ASP.NET-way of doing things and the Fusebox-way of doing things. The rest of this post examines some of these similarities and other aspects of working with ASP.NET. This is mostly an examination of ASP.NET from a (PHP) Fusebox developers point of view.

The Project

The CGIAR Secretariat is responsible for www.cgiar.org. The CGIAR Newsroom is one of the primary sections of their web site. It includes an aggregate RSS news feed of all news items coming out of many of the CGIAR centers. Since many people still are unaware of the advantages of RSS, the CGIAR Secretariat asked if we could set up a system that would allow people to subscribe to the feed via email. Specifically, the system we set up allows people to subscribe and/or unsubscribe via cgiar.org which then automatically sends periodic emails of recently added news items (as they’re added, of course).

The Bottom Line

As an “experienced” web application developer I very much appreciated the ASP.NET-way of doing things. There was nothing in this project that ASP.NET wasn’t able to handle elegantly and more or less efficiently. The project consisted of implementing the following features:

• A public subscribe and unsubscribe form with CAPTCHA
• A nightly script that produces a notification email, with alternate views (plain text and html), consisting of news items that had not been sent in prior emails (which implies keeping track of what’s been sent and what hasn’t)
• A password protected administration interface

The entire project was completed in about 80 hours (including an initial version of the administration interface which was later tabled).

If given the choice of doing the same project in PHP Fusebox, assuming I had the same knowledge and experience with PHP that I had with ASP when I started, would I have chosen PHP Fusebox over ASP.NET? Maybe…

Master Pages

One of the goals of any application framework is to maximize code reuse (and conversely, minimize code duplication). Functions (methods) are one example of how this is accomplished, but when it comes to the presentation level, developers often find they need a more powerful programming model. Both ASP.NET and Fusebox (and many other web application frameworks) provide tools capable of complete solutions. In ASP.NET, a Master Page is a template for all the pages of a site although its functionality goes beyond a simple templating engine. Master Pages also let you define “behaviors” common to all pages, similar, somewhat, to the Fusebox 3 fbx_Settings file or the Fusebox 4 fusebox.init file.

A powerful templating engine will frequently go beyond “one layer” and allow the developer to subdivide sections of the Master to be handled by other parts of the application. ASP.NET offers this functionality directly and at least one project I’ve worked on in Fusebox had the same functionality. I found a few opportunities to use this feature on this project.

Fusebox does not offer a templating engine out of the box, but you can easily create much of this capability in Fusebox 4 (and to some degree in Fusebox 3) using Content Variables and a “layout” circuit. Most projects I work on offer some such circuit.

In the end I got a lot of milage out of Master Pages for this project and hope to be able to use them in future projects for CGIAR.

Postback

By default, every ASP.NET page contains a form that executes on the server. The value of the “action” attribute for the form is the current file. Microsoft has termed this approach “postback” because you post the form back to the same document that created it. In some respects this is similar to the Fusebox implementation of the Front Controller design pattern, where every request is for the same server-side script (e.g.: /index.php) followed by a Query String containing directions on what files, functions, and procedures to execute.

ASP.NET offers the developer server-side elements knows as panels. Panels are “controls” (elements?) that contain other controls. By setting the visible property of a panel you can control whether or not its contents are visible on the page. For the CGIAR project mentioned above, I used this technique to display either the subscription form or the “thank you” message following a successful subscription. I suppose that, if each ASP.NET page is the equivalent of a Fusebox circuit, that each panel could be the equivalent of a Fuseaction. You would simply set the display for all for all of them to false (except the default fuseaction ;-) ) and then display them as needed. Coming from Fusebox, I found the concept very easy to grasp.

Code-behind

Microsoft made an attempt to separate application logic from presentation with .Net. In my opinion, they succeeded.

In order to minimize the amount of raw code found in HTML, .Net provides something known as “code-behind” pages, which are essentially includes with the same name as the file they are attached to. The idea is that your application code goes in the code-behind page and if you need to modify the presentation (the HTML) from within the application code, you do so by referencing elements in your HTML page via their ID attribute (this is an oversimplification but summarizes the approach).

Fusebox, on the other hand, tries to separate code by prefixing file names with one of dsp_, qry_, act_ (and sometimes lyt_).

• qry_ files contain datasource queries and (usually) return some sort of object or array echoed to the browser by a dsp_ file.
• act_ files are for those instances in which you need process data prior to executing a query or echoing to the browser.
• lyt_ files are, in essence, the same as Master Pages in ASP.NET.

In ASP.NET the “HTML” files contain a LOT of .Net namespaced elements. This means the files can be completely valid XHTML (with the single, notable exception of the Processing Instructions found at the top of each page). The benefit is that these files are suddenly very portable and can be consumed by any system capable of reading XML.

If you wanted to reproduce this ASP.NET functionality in Fusebox, you would need to write a plug-in that parses the dsp_ files looking for <fbx: elements and responds accordingly. You could put all of your code in act_ files which would essentially turn them into code-behind files. Now there’s potential open source time sucker!

Data Controls

As one would expect, the data controls are very complete, but figuring out how to do something like nesting GridViews was not obvious and were it not for a Nested GridView walk-through article on MSDN, I never would have been able to figure out how to do it. Furthermore, I’m not convinced executing sql on EVERY ROW of a record set is really a good idea (the authors of the walk-through admit this is not the best approach, but only as it concerns caching…).

Much of the CGIAR Newsroom revolves around their RSS feed (which is a compilation of feeds from all of the CGIAR Centers). ASP.NET 2.0 and above include controls for using XML as a data source and thus facilitating the display of XML data in a web page.

Unfortunately, in version 2.0 of .Net (and possibly higher), using XML as a data source only allows you to display the data. It does not allow you to use the built-in INSERT, UPDATE, and DELETE features of the GridView control. There are work-arounds for implementing this missing functionality but I have to wonder if you save any time hacking in the functionality vs. building the entire administration interface the “old” way (which can be done pretty quickly using XSLT). By my estimates, it’s a draw, at best.

ASP.NET Advantages

For my needs, web controls, validation in particular, significantly reduce web application development time. I simply cannot express how much I like the validation controls and WISH PHP had something similar!

IntelliSense greatly speeds up coding - Microsoft offers several free (web) application development tools that work quite well and are more than adequate for the projects I usually work on and many include IntelliSense.

I don’t think I could have completed this project as quickly without IntelliSense.

ASP.NET Ambiguities and Disadvantages

Since no language is free of sin, here is my list of things that got the best of me while working on this project:

• web.config cannot be part of code repository since it is machine dependent. If application configuration options are so different between deployment environments, then maybe the author of the application should consider using a different development environment. I would prefer to have the application configuration code right in the application tucked into code that “sniffs” the environment and configures accordingly. This makes for MUCH more portable code.
• .Net developers frequently publish their source code, but it usually needs to be compiled so unless you’re into that or have the time to learn how to do it (and do it right), you won’t find the same kind of huge Open Source community of code that exists for PHP
• ASP.NET 2.0 includes some Authentication and Authorization controls, but like most stuff like this, you have to do things the ASP.NET-way or you can’t use these controls. In other words, there is no (apparent) way to retrofit these controls onto existing authentication mechanisms. In the end this is probably a good thing since most existing authentication methods are not very secure, but in the real world most clients simply are not willing to put money into changing existing systems unless you can clearly demonstrate they are broken.
• One of the main complaints of Fusebox 4 was the XML files. Rather than being used simply for configuration, you could easily add business logic to them. More than one programmer has asked herself: “Why bother with XML to represent classes? Why not just use classes directly?” I must say, when programming in ASP.NET, I often feel like I’m simply setting application configuration parameters which, for anything but the most basic interactions, makes programming harder (and possibly more time-consuming) rather than easier (and faster) since you have to have a clear understanding of what state the application is in at the exact point where your code appears. This can be harder than it seems.

In the end, if I had to do it all over again (and had the choice), I would probably stick with PHP Fusebox but I’m grateful I had the opportunity to improve my knowledge ASP.NET and I wish the CGIAR Secretariat the best with their new system.

A través de un boricua viviendo en canarias, aprendí que Chicago encabeza una lista de ciudades donde los hombres prefieren vivir y hace poco, unos amigos nuestros que fueron a EE.UU. en semana santa pasaron unos días en Chicago y les sorprendió, que no esperaban que fuera tan grande, bonita, e interesante (¡cómo me gusta que alaben Chicago!). Si están planificando un viaje a EE.UU., pasen unos días en “Chi-town”. No se arrepentirán.

Las imágenes de Canarias Timelapse son realmente espectaculares. Tengo ganas de ver la película entera. Me pregunto si tiene trama o si son simplemente imágenes con música.
