I've been working on a personal project, from absolute zero to marketing, and it's been a great journey.

Mastering interviews and the most common questions, practicing all the questions to ace them, of course with AI and a lot of language chaining. Real time feedback, complete analysis of interview too. https://intermock.com

Can you explain more? Maybe strategy and what kind of market...

US stock market.

Hey! I have always one doubt about this type of product (pay once). How do you distribute your source font, as well the installer to your customer? Do you use another software for a restricted area to download? Or is the download open to anyone, but you have to offer a license key to run the app?

The app is distributed as a single zip, but the installer requires a license key. Updates are distributed through the duetapp website, which also requires a license key before the update is delivered.

Nice! But is it secure? As the customer already have the source code, what stops him to change the license code? I mean, if the source code is available, I can install it by myself without using the installer.

I know a lot of PHP projects that do this use IONcube loader and mcrypt. So you get the source but it's encrypted.

please, stop it :( how can I work this way?

Why not use http://ell.stackexchange.com/ or http://english.stackexchange.com/ to learn English and maintain the stackoverflow one version?

I agree with "soneca", I am from Brazil too and I'm not so confortable to answer in English, but this never stopped me to ask, to answer or whatever... I mean, the real insight is continous learning, we cannot be in the comfort zone. Distribute and divide will result in duplicate QA, duplicated knowledge and maybe feel a little "it is better to us, not mixing in with these people"

I agree. Any kind of English is way better then people asking questions without making their own effort first. If the language is not clear there will be comments asking for clarifications. Besides I have edited a couple of questions to try and improve grammar. Other people do the same. The world did not collapse.

Because english (and any new language) is hard as fu*k. I'm a also a brazilian, and I think you can agree with me that not eveyone (actualy only 3%) of the brazilians have the condition to learn english. For condition I mean education and financial resources. I know that many of us learned english as we played chrono trigger or Metal Gear Solid, but we had a condition that many of our fellow brazilians did not have.

Ok now I'll spend my entire day on this! However, my friend also visited the website and guess what? The same sequence of streets was showed to him. How this random works?

awesome! public utility :)

Very cool! However, can we send a tutorial too?
