Last October, I wrote a blog post about how vulnerable Google is in its search business (the overwhelming source of its revenue). I realized this vulnerability after discovering that another search engine, DuckDuckGo, was started for less than $10 million, has equivalent search results, a clean looking interface and a low cost of switching. I’ve been using DuckDuckGo for over 8 months now, I didn’t make the switch from Google for privacy reasons, I simply liked the cleaner interface, but I’ll be honest and say that the privacy it offers is something I appreciate. Apparently, I’m among a growing group of savvy searchers.

In this episode of XojoTalk, Paul talks with Ken Whitaker, the Managing Director of Leading Software Maniacs, an expert in leadership, project management and Agile development.
Comments closedOne of the things announced at WWDC last week (that was not announced in the WWDC Keynote) is that Apple has now combined the separate iOS and Mac Developer Programs into the single Apple Developer Program. So what does this mean for Xojo developers?
Comments closedCan I learn to code in Xojo for free? Yes, Xojo is free for development and testing!
Do you have a free book so I can learn to code? Yes, Intro to Programming with Xojo is free!
Can I ask my beginner questions? Yes, the Xojo forum is a gateway to the friendly and helpful Xojo community.
The Xojo language is Object-Oriented. Object-Oriented programming is an excellent way to learn the fundamentals of computer programming. Xojo is also cross-platform, which means you can build apps for all kinds of platforms using a single code base. Xojo is a Rapid Application Development tool, which means it’s developed to make building apps simple and quick.
Comments closedWe’ve occasionally heard from Xojo users that their anti-virus software gives them a warning about Xojo. All of these have been false positives and we ask that you report these to your virus software makers if it happens to you.
Consider the following code:
dim i64 as Int64 = 1234567 dim i32 as int32 = 7654321 i32 = Int32(i64) // cast i64 = Int64(i32) // cast i32 = Ctype(i64, Int32) // convert i64 = Ctype(i32, Int64) // convert
It all seems reasonable enough. Not useful, but seems reasonable. Only one problem. It won’t compile. Why not? The two casts to int32 and int64 will fail. Now why is that?
Comments closedLast week we kicked of the Xojo Wars community battle with a webinar describing what it is and the prizes you can win. Here’s more information for those that could not attend or have not watched the recording.
Comments closedIn this episode of XojoTalk, Paul talks with Mike Cotrone, owner of Intelligent Visibility, makers of some powerful networking apps that are all created with Xojo.
Comments closedIf you do any work with private/public key cryptography, the addition of the Crypto library last year made it finally possible to create and verify digital signatures as well as encrypt and decrypt data. Using keys with other systems requires a little more work to convert them to and from the PEM format.
Comments closedThanks to some assistance from William Yu and the folks at combit, we now have a sample project that shows you how to use List & Label with Xojo. List & Label is a Windows (.NET-based) reporting tool that can create some sophisticated reports.
