B4J: ABMaterial WebApps and SEO (Search Engine Optimization)

SEO

A feedback case I got from one of the users of ABMaterial, Herbert, was the question how ABMaterial coped with SEO-optimization. To be perfectly honest, I hadn’t really though about it. I  had a couple of things already, like headers, bold text, a page title and description.

As any good programmer,  if it looks nice, is user friendly and works as expected, my work is done and users will find and like it. No?

And it kept me thinking.  So this morning, lying awake at 4  o’clock (sleeping is highly overrated IMHO and an invention of the Bed Consortium, but I’m sidetracking), I decided to learn more about SEO and how it could be implemented in ABMaterial.

Herbert gave me some links, so I started reading up.

Looked like I had some things right already, but ABMaterial could use some polishing.

For starters, I added some extra properties to the ABMaterial page object that will be saved in the generated html file:

pageTitle: very important, pick good keywords
pageDescription: keep it around 140 to 160 chars
pageKeywords: a comma delimited string containing your page keywords
pageHTMLName: it is always index.html in ABMaterial, but it’s better to give it some name using keywords, like ‘abmaterial-custom-component.html’, use hyphens (-) between words to improve readability
pageSiteMapPriority: a value between 0.00 and 1.00, see further
pageSiteMapFrequency: how frequently the page is updated (never, none, always, hourly, weekly, yearly, …), see further

Headers:

Covered!  ABMaterials labels can have headers like <h1>, <h2> so we’re ok.  Tip: create only one <h1>!

<h1>Most Important</h1>
<h2>Second Most Important</h2>
<h3>Third Most Important</h3>

Bold:

Got it: You can use markers like {B}{/B} in labels to set text in bold/strong.

Use tag in a image:

Ah, needed some changes.  I misused it.  Thinking ‘who the #?@! can’t show images anymore these days‘, I used it as an image toggle property.  Changed it now so it can be used properly.

Hyperlinks:

Added some extra markers {AS}{/AS} in the ABMLabel Component so you can add a title.

{AL}http://www.website.com/page.html{AS}keyword{/AS}{AT}my visible text{/A}

will result in:

<a rel=”nofollow” target=”_black” href=”http://www.website.com/page.html” title=”keyword”>my visible text</a>

sitemap.xml and robots.txt:

The Sitemaps protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling. ABMaterial has the possibility to generate a sitemap.xml file and a robots.txt file (for sites like Ask.com).

What does it look like Alwaysbusy, I hear you ask. Well, something like this:

<?xml version=”1.0″ encoding=”UTF-8″?>
</pre>
<urlset
xmlns=”http://www.sitemaps.org/schemas/sitemap/0.9”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”

<changefreq>yearly</changefreq>
<priority>0.50</priority>
</url>
</urlset>

To generate this is easy in ABMaterial, and needs just a couple of things:

  1. In ABMShared, add a property  public AppPublishedStartUrl as String = “http://yoururl.com”.

  2. In the initalize() method of ABMApplication, add ‘ABM.AppPublishedStartUrl=ABMShared.AppPublishedStartUrl.

  3. In the BuildPage() method of each page, set page.PageHTMLName=”your-good-keywords.html”

  4. Also in BuildPage(), add page.PageSiteMapPriority = “0.50” (number between 0.00 and 1.00, and don’t set them all to 1.00, that makes them equally important)

  5. Also add page.PageSiteMapFrequency = ABM.SITEMAP_FREQ_MONTHLY (use one of the contstants)

  6. If you use a ABMNavigationBar, update the url of each sidebar item in ABMShared, e.g. page.NavigationBar.AddSideBarItem(“Contacten”, “Contacten”, “mdi-action-dashboard”, “../StartPage/your-good-keywords.html”)

  7. In ABMApplication, also change your InitialPage=”your-good-keywords.html”

  8. In ABMApplication, change ‘index.html’ in the AddPage() method to Page.PageHTMLName

When you start your app, the sitemap.xml and robots.txt files will be generated next to your apps html file. After publishing it to your final site, you let the search engines know you want to submit your site.

You should be able to use these sitemap-submission URLS. Put the full URL to your sitemap, including http://, after the = sign:

http://www.google.com/ping?sitemap=

http://www.google.com/webmasters/sitemaps/ping?sitemap=

http://www.bing.com/webmaster/ping.aspx?sitemap=

http://submissions.ask.com/ping?sitemap=

http://www.didikle.com/ping?sitemap=

So, you’re already one step ahead of many other tools when you use B4J and ABMaterial!

Of course, your content will be the most important part to atract users and get high rankings in the search engines, but it never hurts giving them some help.

If any SEO expert reading this article has some other ideas, please post them.

ABMaterial 1.05, supporting all this, will be send to the donators early next week. Quite some goodies included in this release!

Head to the B4X website, download your free copy of B4J and go to the forum to download the ABMaterial framework.

B4J: 4.0 now supports HTTP/2, perfect tool for my ABMaterial framework

ABMaterial

You all know me as a Xojo fanatic, but lately I lost a bit of interest because the focus of the last year was so much about Apple, and Windows/Linux was a bit forgotten.

So I got back to my other favorite, B4X.  And what a pleasant ride it has been so far! It truly is a far to little known gem with so much power under the hood. Creating apps for Android, iOS, Desktop and Server apps is a blast.

Being able to share code between devices, having a simple but powerful (free) IDE, a very active community and a developer that really listens was quite refreshing.

My next project was writing a Material Design framework for Web Apps, without having to write a single line of HTML, CSS or JavaScript.  And quickly, it became obvious B4J was the one tool that could do it. ABMaterial was born.

Using very little code, you’re able to write beautiful (based on Material CSS) and powerful (B4J really stands out here) WebApps.  The enthusiastic crowd at the forum has pushed me through several nights continuing to write on the framework and has made me, although some polishing is still needed, a very happy camper.

It will be very useful to write WebApps (automatically adapting to the screen size of your device), and I even see it to be great to write nice interfaces for your Raspberry Pi projects. It consists of 25+ ‘themeable’ controls and some easy-to-use helpers to design your layouts.

To prove B4J is really on edge with the latest technologies, Erels latest release 4.0 for Christmas now supports HTTP/2. Benchmarks showed a big difference in speed and will undoubtedly be very useful for mobile devices.

I’ve set up a live demo of ABMaterial on my modest media center computer here. So, be gentle with her…

Or if you want to try it out yourself, head to the B4X website, download your free copy of B4J and go to the forum to download the ABMaterial framework.  The current ‘public’ version is 1.03.  Donators get updates (1.04 as at time of writing) about 2 to 3 weeks beforehand so I’m able to better control questions/feature requests or bugs (aaarrhh!).

I wish you all some very happy Holidays and I hope I’ll see you all next year for some more fun programming projects!

Xojo: Sketching with Real-time Contrast Preserving Decolorization and Potrace

Sketcher

Always looking for some ways to learn the computer to ‘see’, I came accross two very interesting algorithms: ‘Real-time Contrast Preserving Decolorization’ by Cewu Lu, Li Xu and Jiaya Jia. And Potrace by Peter Selinger

Decolorization – the process to transform a color image to a grayscale one – is a basic tool in digital printing, stylized black-and-white photography, and in many single channel image processing applications. RTCPD is aiming at maximally preserving the original color contrast alleviate a strict order constraint for color mapping based on human vision system.

An example can be seen here:
RTCPD

The second algorithm Potrace(TM) is a tool for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image.

Example:
potrace

Playing around with both algorithms, I came up with the idea to use them for a project I had in mind for some time: Sketching pictures on my wall using a Pico projector.

First I had to implement both algorithms in Xojo. The result of RTCPR can be found in the attached source code in the RTCPRGB2Gray() method:

Private Sub RTCPRGB2Gray(pic as Picture)
  dim imcols as Integer = pic.Width
  dim imrows as Integer = pic.Height
  dim sRGB as RGBSurface = pic.RGBSurface

  dim Mat(-1,-1) as ABDoubleVector
  redim Mat(imrows-1,imcols-1)
  dim c as Color
  for y as Integer = 0 to  imrows - 1
    for x as Integer = 0 to imcols - 1
      c = sRGB.Pixel(x,y)
      mat(y,x) = new ABDoubleVector(c.Blue, c.Green, c.Red) ' switch to BRG
    next
  next

  dim s as Double = 64.0 / sqrt(imcols*imrows)
  dim cols as Integer = (s * imcols) + 0.5
  dim rows as Integer = (s * imrows) + 0.5

  dim sigma as Double = 0.05
  dim W() as ABDoubleVector = wei()

  dim P() as ABDoubleVector
  dim det() as Double

  dim pos0() as ABDoublePoint
  dim pos1() as ABDoublePoint
  for i as Integer = 0 to cols - 1
    for j as Integer = 0 to rows - 1
      dim x as Integer = (i+0.5) * imcols/cols
      dim y as Integer = (j+0.5) * imrows/rows
      pos0.Append new ABDoublePoint(x,y)
      pos1.Append new ABDoublePoint(x,y)
    next
  next

  pos1.Shuffle

  for i as Integer = 0 to pos0.Ubound
    dim c0 as ABDoubleVector = mat(pos0(i).y, pos0(i).x)
    dim c1 as ABDoubleVector = mat(pos1(i).y, pos1(i).x)

    add c0,c1, P, det
  next

  cols = cols / 2
  rows = rows / 2

  for i as Integer = 0 to cols - 2
    for j as integer = 0 to rows - 1
      dim x0 as integer = (i + 0.5) * imcols / cols
      dim x1 as integer = (i + 1.5) * imcols / cols
      dim y as integer = (j + 0.5) * imrows / rows

      dim c0 as ABDoubleVector = mat(y, x0)
      dim c1 as ABDoubleVector = mat(y, x1)

      add(c0, c1, P, det)
    next
  next

  for i as integer = 0 to cols - 1
    for j as Integer = 0 to rows - 2
      dim x as integer = (i + 0.5) * imcols / cols
      dim y0 as integer = (j + 0.5) * imrows / rows
      dim y1 as integer = (j + 1.5) * imrows / rows

      dim c0 as ABDoubleVector = mat(y0, x)
      dim c1 as ABDoubleVector = mat(y1, x)

      add(c0, c1, P, det)
    next
  next

  dim maxES as Double = -99999999999
  dim bw as Integer
  for i as integer = 0 to w.Ubound
    dim es as Double
    for j as integer = 0 to p.Ubound
      dim l as Double = P(j).x * W(i).x + P(j).y * W(i).y + P(j).z * W(i).z
      dim detM as Double = det(j)

      dim a as double = (L + detM) / sigma
      dim b as double = (L - detM) / sigma

      es = es + log(exp(-a * a) + exp(-b * b))
    next
    es = es / (p.Ubound+1)
    if eS &gt; maxEs then
      maxEs = Es
      bw = i
    end if
  next

  dim result(-1,-1) as Double
  redim result(imrows-1,imcols-1)

  for y as Integer = 0 to  imrows - 1
    for x as Integer = 0 to imcols - 1
      result(y,x) = mat(y,x).z*W(bw).x + mat(y,x).y*w(bw).y+0
      result(y,x) = mat(y,x).x*W(bw).z + result(y,x)*1+0
      sRGB.Pixel(x,y) = rgb(result(y,x),result(y,x),result(y,x))
    next
  next

  bw = 0
End Sub

Potrace is a complete framework to trace an image and converting it to Xojo did take some time. While writing it, I also made some changes to it to optimize the result. One of it was doing my own thresholding using the surrounding pixels to smoothen the edge detection.

Snippet:

  dim v, v1, v2, v3, v4, v5, v6, v7, v8 as Integer
  dim ex,ey, weight, weighttotal, total as Double

  'SISThreshold2 alain
  for y = 1 to H - 2
    for x = 1 to W - 2
      v = sDebugPicRGB.Pixel(x, y).red
      v1 = sDebugPicRGB.Pixel(x+1, y).red
      v2 = sDebugPicRGB.Pixel(x-1, y).red
      v3 = sDebugPicRGB.Pixel(x, y+1).red
      v4 = sDebugPicRGB.Pixel(x, y-1).red
      v5 = sDebugPicRGB.Pixel(x+1, y-1).red
      v6 = sDebugPicRGB.Pixel(x-1, y-1).red
      v7 = sDebugPicRGB.Pixel(x+1, y+1).red
      v8 = sDebugPicRGB.Pixel(x-1, y+1).red
      ex = (v1+v2+v5+v6)/4
      ey = (v3+v4+v7+v8)/4
      if ex &gt; ey then
        weight = ex
      else
        weight = ey
      end if
      weighttotal = weighttotal + weight
      total = total + weight * (v)
    next
  next

  dim  Threshold as Integer = 128

  if weighttotal &lt;&gt; 0 then
    Threshold = total/weighttotal
  end if

  dim ret as Boolean = (sDebugPicRGB.Pixel(0, 0).Red &gt;= Threshold)

  for y = 0 to H
    for x = 0 to W
      c = sDebugPicRGB.Pixel(x, y)
      if c.red &gt;= Threshold then
        Matrix(x+1, y + 1) =true
      else
        Matrix(x+1, y + 1) = false
      end if
    next
  next 

  for x = 0 to MatrixW
    Matrix(x,0) = true
    Matrix(x, MatrixH) = true
  next
  for y = 0 to MatrixH
    Matrix(0,y) = true
    Matrix(MatrixW, y) = true
  next

This gave me all the tools to start tracing an image. But for my project I wanted to have a sort of ‘sketchy’ feeling. For this I needed a couple of things because I wanted the drawing and painting to be done gradually. I had to build it with delays, repetition, randomization and color fading. I wanted to start from a picture and create something like this:
jobs

DrawImage() does all that. It first draws the beziers with some little random mistakes in grey. A gradual painting is then used to fill in the polygons. Finaly it repeats the process with the correct lines in white.

You may notice that a lot of code is redundant, but this is intended because I needed to have enough delays to mimic a more natural feeling.

Here is a demo video showing the result of this project on my wall. It takes about ten seconds before it starts drawing as I had to grab my camera :-). Five different images are drawn.

The project with full source code can be downloaded here

Greetz!

Xojo: CHIP-8 Emulator

CHIP-8
Some weeks ago, Ashot Khachatryan contacted me on the Xojo forum with the question if I would be interested in writing a CHIP-8 Emulator in Xojo. I had no knowledge of the system and he had written a good part of an Emulator himself. It had some hard to find bugs in it and he was kind of stuck. As it is hard to debug someone elses code, especially if the subject is not very well known, I decided to start from scratch. Or, to say it in Barney Stinsons words, Challenge accepted!

CHIP-8 is an interpreted programming language, developed by Joseph Weisbecker. It was initially used on the COSMAC VIP and Telmac 1800 8-bit microcomputers in the mid-1970s. CHIP-8 programs are run on a CHIP-8 virtual machine. It was made to allow video games to be more easily programmed for said computers. Input is done with a hex keyboard that has 16 keys which range from 0 to F. The ‘8’, ‘4’, ‘6’, and ‘2’ keys are typically used for directional input.

There are a number of classic video games ported to CHIP-8, such as Pong, Space Invaders, Tetris, and Pac-Man.

So, the big question was, could we write a CHIP-8 CPU Emulator in Xojo? It needs to be able to read ROMS, interpret Opcodes, show it on the 64×32 pixels screen and handle input. An Opcode is a two bytes code like 00E0 (Clears the screen).

The ‘Virtual Machine’ ABCH8CPU would need to handle a couple of things:
Screen: a picture of 128×64 pixels
Memory: 4096 bytes. I decided a memoryblock would be ideal in Xojo to handle this
Registers: a CHIP-8 has 16 8-bit registers (V0-VF). A Byte array will be used
Timers: a byte array of size 2
Sound: Beep is used
Input: the Keyboard.AsynckeyDown() method would handle the state of the 16 keys.

There are a number of projects on the net in other programming languages available. (Just google CHIP-8 source code). I’ve studied several of them before I’ve wrote my Xojo version.

Here is the result (didn’t spend much time on the GUI):

ABChip8
It can handle CHIP ROMs and SCHIP (Super CHIP) ROMs. Unfortunately, speed is terrible. Xojo may not have been the right language to write this project in, but look at it as a proof of concept. And it can probably be optimized too, as I wrote this emulator in an evening or two.

You can change the keyboard (AZERTY/QUERTY) to emulate the 16-Keys keyboard. A memory dump and a list with the interpreted Opcodes is also shown.

All in all, this was a fun project to do!

B4i: 1 … 2 … 3 … Ready … Go!

B4i2
This weekend I’ve found some time to setup my testing environment for B4i, the latest brainchild of Anywhere Software. I must say, being a novice Mac user, setting everything up went very smooth.

The only parts I got into some trouble was my own fault, as I went though the setup tutorials, videos and Beginners Guide just a little bit to fast. Eager to get started, I skimmed through them and forgot some important steps.

First I paid my obligatory taxes to Apple: $99/year. (Programming for Android only sets you back with a one time fee of $25). Only a couple of minutes later, my account was activated.

One part that may have gone a bit to fast for a first time Apple developer was the creation of an App ID. As Erel had his system already setup when he made the video and could just pick an App ID, he did not show us how to create it in the first place. It is mentioned further in the post you can create a single wildcard App ID if you put a .* at the end, but this was not very clear from the tutorial. So, this is how I did it:

Click to enlarge

Another RTFM moment was when I wanted to install the B4i-Bridge app on the device. I started watching the video and forgot to read the bold sentence above it:

Before you install B4i-Bridge you must install the B4I certificate. This step is not shown in the video. Open Safari (device browser) and navigate to: www.b4x.com/ca.pem

Clearly stated, but hey, I was in a hurry…

I first tried the Hosted Builder option to compile the app. Very smooth and a excellent alternative for Windows developers who do not own a Mac. And for $26 a year, a bargain.

But, as I want to experiment with creating libraries myself in Objective-C, I wanted to install the local MacBuildServer. Again, following the tutorial, everything went very well. Downloading XCode took most of the time.

One note: Make sure your Mac is in the same IP range as the rest of your development environment. At first, the Mac had IP 192.168.40.116 while the rest was in the 192.168.1.x range. So it didn’t work.

The rest was pure cosmetic. I added an shortcut on the Mac to start the MacBuildServer, and one on the PC side to shut it down.

Creating the shortcut on the Mac side went like this:

  • Open up a terminal
  • go to the folder where you unzipped the macserver-aa (in my case, it’s on the desktop, so it looked like this:

    $ cd desktop
    $ cd macbuilder-aa

  • create a text file

    $ shout start.command

  • add the following lines (adjust the cd to the path where your MacBuildServer is)

    #!/bin/sh
    cd /Users/Alwaysbusy/Desktop/macserver-aa
    java -jar B4iBuildServer.jar

  • save and in the terminal type:

    $ chmod -x start.command

  • Right click on start.command, pic ‘Get Info’ in the menu and rename it to something like ‘B4i Build Server Start.command’.
    Click ‘Hide extension’
  • And change the icon to a nice B4i one. I’ve ripped the B4i icon from the exe (sorry Erel) and saved it as a .png. In case you need it, here it is:
    B4i
    Open the png on the Mac in preview and copy it (Edit – Copy). In the ‘Info Panel’ of the command file, click on the icon until it gets a blue rectangle. Then you can do ‘Edit – Past’.
    In my case, it looked like this:
  • B4i3

    Coming from Windows and being used to creating .bat files, this is all rather complicated on a Mac I must say.

    On the PC side I created also the icon to shut the MacBuildServer down. Enter http://:51041/kill in your favorite browser. Create a bookmark and drag it to your desktop. Rename it to something like ‘B4i Build Server Kill’. You can also change the icon:

    • Right click on the shortcut and pick ‘Properties’
    • Press ‘change icon’
    • Browse to where you have installed B4i
    • Pick B4i.exe and select the icon

    So (besides my shortcut creation problems on a Mac), setting up B4i is a breeze! I’m ready to add some serious iOS programming experience to my portfolio.

    Here are some quick links to the tutorial parts I used:
    Creating a certificate and provisioning profile
    Installing B4i-Bridge and debugging first app
    Local Mac Builder Installation

    See ya!

    Xojo: Release 2014R3 with iOS support

    Xojo with iOS support
    We are spoiled this Christmas! Xojo has released a new update of their cross-platform development tool, and this time it includes a new one: iOS.

    I think congratulations is in order to the Xojo dev team! The wait has been long and there are a lot of eager programmers wanting to explore the world of mobile development. There are some changes in the framework that will it make somewhat harder for hardcore developers (me included) who have already huge business logic libs. But I’m sure the Xojo community will come up with some tricks to make the transition faster.

    Already some members are trying to set-up some kind of central place to cover some missing controls/functionalities with Declares. I hope they share the source code, so we can all learn from it!

    Here is what the wizards of Xojo have to say:

    Xojo, Inc.:
    Latest release allows users to create high-quality, native iOS applications in the same way they develop desktop and web apps today.

    Xojo users can now build iOS apps in the same way desktop and web applications are created. Users can drag and drop to create the user interface and use one straight-forward programming language to implement the functionality of their app. Xojo makes it significantly faster and easier to create native iOS apps than any other tool. Many iOS business apps rely on a web-based server application that provides business logic and database access. Xojo is the only development tool that provides the ability to create both a native iOS client application and a native server application from a single language and tool. Users experience true multi-platform development with Xojo, creating their app on one platform and delivering a completely native product to users on another platform.

    Geoff Perlman (Xojo Founder and CEO):
    “Xojo 2014 Release 3 represents a huge leap forward for us as we are now have a mobile development platform. Adding iOS to Xojo has been the top feature request from our users and we are pleased to deliver. By expanding their Xojo applications from the desktop and web to iOS, our developers are now able to broaden their target audience to a whole new range of prospects.”

    This latest release adds 160 improvements and over 20 new features. In addition to the new iOS framework, this release also adds improvements to the web framework and includes new classes that make creating international applications easier. Further, web applications can now respond to requests from search engines such as Google, making their content searchable on the web.

    Xojo 2014 Release 3 feature highlights include:

    • New iOS framework.
    • New Text data type and supporting methods for improved text handling.
    • New Auto data type for storing any type or object.
    • New Xojo.Core classes that make creating international applications easier.
    • SSLSockets now support newer security protocols like TLS v1.1 and v1.2, and now defaults to TLS v1 instead of SSLv3.
    • For Web applications, a new HandleURL event allows processing requests for URLs that previously could not be served. This feature also gives you the ability to respond to requests from Google and other search engines.


    So as of now, we programmers, have two new development tools added to our repertoire: Xojo iOS and B4i (see previous article). Both with their advantages and drawbacks. As a Windows programmer it is nice for me to be able to develop iOS apps on my own platform with B4i. At the time of this writing, Xojo iOS is Mac only. But who knows, maybe there is some secret Santa out there that will put a Mac mini under my tree (hint!).

    But this a personal view of course. My code lib for android (B4A) is also vast and the conversion for my mobile apps is probably going to go smoother when I stay in the same language and OS. So in the end, it’s up to you to make a choice (or use both)! After all, it’s almost Christmas, so you all deserve a treat…

    Happy programming!
