Smartphone Encryption is a Red Herring

EnigmaMachine.pngAs the Founder and CEO of a software company that makes a development tool for mobile platforms, as well as for desktop and web, I have a lot of experience with encryption. The current controversy over encryption is really important to me. During World War II, the Germans created a way of sending encrypted messages to commanders in the field. The device came to be known as an Engima machine. It looked like a typewriter but had an encryption key that changed a message into unreadable noise. That message could only be decoded if you knew the key used to encrypt it. The Allies worked very hard to get their hands on one of these devices so they could learn how it works and be able to decrypt the messages and know what the German military plans. Ultimately the Allies figured it out and it helped them win the war. If this has peaked your curiosity, check out the movie U-571 (a fictional account of the effort to obtain an Enigma machine) and The Imitation Game about the team that figured out the encryption key.

O Retina, Retina, wherefore art thou Retina?

eyeball.pngDuring my keynote address last April at XDC, the Xojo Developer Conference, I said that we would be adding Retina support (the OS X feature that provides for ultra-high resolution displays) to the OS X framework in the 4th quarter of this year. We have been working very hard on Retina support both for the OS X framework and for the IDE itself. We didn’t want to stop there though. Windows also supports ultra-high resolution displays. For Windows, this technology is called HiDPI. Xojo is a cross-platform tool so we decided we should support both Retina and HiDPI, and do it in such a way that you don’t have to do much of anything and they just work.

UPDATE: Xojo Retina is here, April 2016

Is Apple killing off mobile ads?

The issue of mobile ads is of particular interest to me as I am forced to think of mobile ads from three different perspectives. First, as a developer since Xojo can be used to create iOS apps; then as an entrepreneur because we advertise Xojo via mobile ads; but also as a personal consumer of mobile ads.

I think I’m on firm ground when I say that mobile ads are universally hated. We hate them more that TV commercials and certainly more than magazine ads. Why is this?

Should We Fear The Machine? Self-driving cars and the computers of our future

When I was a kid, computers were responsible for almost nothing, at least in my daily life. Big companies used computers to run their accounting departments and NASA used them for analysis, but most peoples’ daily lives were unaffected by the existence of computers.

Left Handed: Being Outside The Norm

Being that it’s Left Handers Day and I am left-handed, I thought I’d share some interesting facts about being left-handed and how it relates to Xojo, Inc.

At Xojo, the percentage of left-handed people has always been high. Currently 33% of our staff is left-handed. I can’t explain why that is. I don’t think we have a bias towards lefties. On the other hand, my brother who is a lawyer specializing in employment law, will tell you handedness is not a protected class in the US, so we could discriminate if we wanted to do so. Nah, you righties are interesting and fun to watch. 🙂

Is the NSA going to get you to switch to DuckDuckGo?

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.

The New Xojo Framework: Ch-ch-ch-ch-changes

In the ideal world when you do something, you do it right the first time. In the real world, we learn more each day and what seemed right yesterday, a month ago or a few years ago, may no longer be right today. Xojo has been around for a long time now and in all that time we have learned a thing or two. One of the things we have learned is how to deal with errors.

Einstein’s Special Relativity and Software Projects

In 1905, Albert Einstein published a paper revealing his theory of Special Relativity to the world. The theory says that not only do mass and energy have an equivalence (an idea that was not new) but that they have a specific equivalence expressed in the equation E=mc2. That equation basically says that the faster you go, the more energy you need to continue to accelerate. The unfortunate consequence of this is that you can’t reach the speed of light because at that point, your mass would be infinite which is of course, impossible.

It occurred to me recently that this concept applies to more than just the cost of going acceleration. For example, the larger a company gets in terms of just about any way a company is measured (revenue, profit, employees, customers, etc.), the harder it is to continue growing at that same rate. It isn’t that big companies don’t grow, they of course do, but they don’t grow a lot compared to smaller companies. It’s not difficult to grow from $100,000 to $1 million in sales compared to growing from $1 million to $100 million.
