PHP money string conversion to integer error

I have a small financial application with PHP as the front end and MySQL as the back end. I have ancient prejudices, and I store money values in MySQL as an integer of cents.

Making money with Open Source as a developer?

Is a double really unsuitable for money?

I always tell in c# a variable of type double is not suitable for money. All weird things could happen. But I can't seem to create an example to demonstrate some of these issues.

Business Model for a Good Software App

I developed an application, working fine and in a closed beta stage for last 1.5 years, it's been 3 years on development. Quite stable, full-featured and polished as well. It's a software for a certain market and can compete with other applications (only 5-10 decent applications exist in the same market). Simply put I believe in it and b...

QA engineer and more money or software engineer with less

I may be presented with the opportunity to be a part of an engineering-intensive QA team (unit/scenario test automation) for more pay. Currently, however, I am a software engineer, which sounds more prestigious to me. More money also sounds nice, though, but at what point is it worth it? ...

Should I support Linux for a .NET application?

I've seen this blog post : Why you should support Linux and Mac? and it kind of changed my mind about the subject. I'm developing an application (something like a SEO tool, to analyse a website and recommend stuff) in VB.NET. Theoretically I can support Linux and Mac users with Mono. Does it really worth it? And how painful is it to ...

Stupid, but commercially successful software

Recently I read that the author of the 99 cent iFart Mobile application for the iPhone makes nearly 10,000 US$ a day (!)¹ with his flatulence simulator. Do you know of any other silly or useless, but commercially successful software products? Perhaps there is a pattern and we all can find recession-proof software niches as competition h...

How to seek a small amount of venture capital?

Hello, I am developing an app for which I need a more experienced developer to test my code, and also for UI & design work.

Can a single developer still make money with shareware?

I'm wondering if the shareware concept is dead nowadays. Like most developers, I've built up quite a collection of self-made tools and code libraries that help me to be productive.

Want to sell own application. Where to start?

I developed a handy little application that can help a lot of people.

Should you charge a customer for bug fixes?

I always have, either by factoring it into the cost initially or just charging by the hour. Upon talking with another developer, who is older and been around the industry longer than I have been, he said that wasn't honest.
