Just fixed a web site problem

Today I saw the website was generating some spurious messages related to security features installed on this web site. This has now been repaired (I hope!)

All of my blogs receive significant security attacks every day.   A variety of security measures are installed, operating in a mult-level scheme of barriers to the attackers.

It is unfortunate that these attacks occur to even small web sites that are run primarily as a hobby.

Source code downlinks fixed

Two readers alerted me to problems downloading the source code on the Downloads page on this web site, and the source code for my book on App Inventor graphics and animation.

A software update on the server appears to have changed how some default file directories were appended to filenames.

The problem appears to now be fixed. Thank you very much for letting me know of this problem.


Apologies for lack of updates

Sorry for the lack of updates and posts to this web site. I have had a lot going on – and right now, we are in process of moving across the state. Eventually things will be settled down. I completed several interesting App Inventor projects but have lacked time to get them posted here. Hang in there – I intend to be back!

Visit the primary web site at learn2c.org

This web site – appinventor.pevest.com – is no longer the primary web site for our App Inventor tutorials. However, this web site will remain here indefinitely as many people link to it, including search engines and my own e-books 🙂

The new, short and easy to remember URL is Learn2C.org as in “Learn 2 Code”

Unfortunately, for reasons I will not get into, it is not possible to integrate the two web sites together. So appinventor.pevest.com will remain “as is”, and Learn2C.org will become the primary focus point.

I am looking into having Learn2C automatically cross post to the appinventor.pevest.com web site but that has not yet implemented. But I’d like to do that for those that already follow the appinventor.pevest.com web site.

My apologies for not doing a lot of updates during 2018. I have already written some new code examples (Bluetooth LE anyone?) and am working on more in that area. These tutorials will appear once I have completed the entire series of example programs. There are also other items in the works that I cannot talk about yet.

Web site issues

First, the update to WordPress 5 did not go well with this web site. The web site is running WP 5 now but it has caused many problems, at least one of which I seem unable to work around or fix.

Second, I tried to reconfigure the web site for something I have been working on, but it appears what I wanted is not possible. This temporarily left the web site over night on 10 January 2019 (UTC) unable to handle incoming search links properly. I have backed out that change and search queries (via Google) should resume landing on the correct pages.

Third, around 31 December to 2 January, this web site was mostly inaccessible due to my ISP making a change to their network, which made their SQL database server inaccessible. This impacted multiple web sites, including the ISP’s own web site!

I am continuing to work on these issues with apologies for the inconvenience.

Google will be discontinuing Google Fusion Tables at end of 2019

Google created a cloud-based data base system called Fusion Tables. Later, support for Fusion Tables was added to App Inventor.

If you have used Fusion Tables, you will need to update the code to use a new data base system. You might also consider third-party App Inventor-based development systems such as Appy Builder.

Google has sent out an email advising Fusion Tables users that they will be discontinuing Fusion Tables – literally, the database service will go away on 3 December 2019.

Unfortunately, there is not yet a great alternative database for App Inventor apps other than to switch to Appy Builder.


Google Fusion Tables  was launched almost nine years ago as a research project in Google Labs, later evolving into an experimental product. For a long time, it was one of the few free tools for easily visualizing large datasets, especially on a map. Since then, Google has developed several alternatives, providing deeper experiences in more specialized domains.

In order to continue focusing our efforts in these areas, we will be retiring Fusion Tables. We plan to turn down Fusion Tables and the   Fusion Tables API  on December 3, 2019. Embedded Fusion Tables visualizations — maps, charts, tables and cards — will also stop working that day. Maps using the  Fusion Tables Layer  in the Maps JavaScript API v3.37 will start to see errors in August 2019.

Here are some next steps to consider:

Learn about alternative tools

Several new Google tools have been developed over the years, and we encourage you to visit the  Help Center  to learn which ones fit your use-case.

Teams at Google have developed internal tools that can create   powerful map visualizations. We are working to make some of these tools publicly available and will have more to share in the coming months—sign up    to stay in touch.

Download your data    

Filter by  “type:table”  to pull up a list of your tables in Google Drive. Download data from an individual table by following  these instructions. If you have a lot of tables, we will make it easy to download all your data in one step via   Google Takeout   starting in March 2019.

Thank you for supporting Fusion Tables over the years. If you have feedback, visit the Fusion Tables Help Forum.
