Hi! I was dreaming about buying a laser cutter and lamenting how expensive they are specially considering that I live in Brazil, shipping adds a lot to the cost, and Brazilian taxes are insane!

Then I found out yesterday about low cost 40W lasers. Seems like a well hidden secret! 

I'm thinking about buying one for myself, and I'd like to know if anyone recommends some specific supplier on eBay or Amazon. I found it on Amazon for US$ 500, and over eBay for a lower price (US$ 389). I'm a longtime Amazon customer though and I fear that eBay may have a harder time with Brazilian customs than Amazon.

There's one big issue that's the software. Some units come with different software. I would prefer my unit to work with Corel Draw, and for what I've seen on videos this is possible. Which is the best unit for this?

I also noticed that there are small variations in the control panel. Some have digital controls, while other units have analog controls. Is there a big difference between the two?

The startup world is dominated by a winner takes all mentality, which also happens to reflect a masculine way to do things. So it's no wonder that women are a minority in the startup tech scene. Current women leaders tend to be the exception that prove the rule.

Boys break things to see how they work. Boys fight just to prove they're stronger. Boys do things for the sake of doing. Girls, on the other hand, may be interested in the same: understanding how things work, or winning a game. But they act differently. It's not for lack of strength or will. It's just a different way of doing things. Girls seem to be more interested in the building process, and in the way the whole works after it's done, than in doing it just for the sake of doing.

Boys also like to prove themselves by beating the impossible. And the startup industry - with it's VC-dominated mindset looking for huge exits - takes advantage of this behavior.

Startups today reminds me a lot the armies from ancient empires, including Sparta, Rome, and more recent empires up to the early 20th century. In the old times, young boys fought to prove their worth and to grow in power. Many died trying. Now, young founders became cannon fodder for the leaders, risking their futures and careers in the search of the "big exit". They're motivated, they're inexperienced, they don't know the impossible. The youth of old were willing to face death to "be someone". The youth of today is willing to do anything to "make it big". The leaders don't care about those who fail, as there's an interminable supply of other young fellows willing to take the risk.

In a few years from now, we may be talking about the "failed generation", of the thousands of promising careers destroyed by the dream of a billionaire exit. For each Mark Zuckerberg there will be hundreds of poor folks wondering where they career led them, after a few broken startups and no proper resume to talk about when applying for a job.

The good news is: as in everything, women participation will increase over time, and help change they way things are today. Women will question the assumptions and help build a new way of doings things - which will be fine, and improve upon the current model.

That's more than hope; it's the way things are. Our society greatly benefited of increasing women participation in science, work and politics over the past centuries. And that's what makes it a great thing to happen.
