What I learned at AppSecEurope and my thoughts for the future

Last week I was fortunate enough to attend AppSecEurope. There was much discussion about DevSecOps, the hottest trend today in AppSec. The talks were really inspiring and cover this topic from various vantage points. However, I would like to discuss two issues that are extremely relevant for the future of the industry and were missing from the discussion at the event. OWASP Glue Glue is a tool that coordinates various security tools. It makes the integration of various security tools with…

Our journey to better personalization: using a recommendation engine – part 1

Imagine you just finished watching a great movie on Netflix, and immediately afterwards you receive the following recommendation for your next movie: If you’re into old chinese movies, then you’re in luck. But if not, you’ll probably be frustrated and turned off by this terrible recommendation. This example shows how important the use of personalization is and how it impacts your users’ feelings and thoughts about your product. Recommendation engines are a very effective way to personalize your product and…

The keys to creating an effective user survey

The hardest task as a product manager is the guessing game. Basically, we have to guess what users want or need. If you’re in the B2B industry and you want to think about your next step, all you have to do is ask your business users what they need. Add some development estimation to the mix, and you have yourself a roadmap. However, in the B2C industry, and especially in the mobile apps industry, you can’t really do that. First of…

Keeping your Redis in shape in 3 simple steps

Redis is a great NoSQL database, not only for cache, but also as a primary data source (and we’re doing both!). Because it is so popular, there are many hosting solutions for Redis – and most of them offer plans with different memory sizes. If you use a hosting solution like we do, then you’re probably encountering a similar problem: how do you keep your Redis instance in the plan’s limit? Here I explain how to do this easily by…

Userless User Authentication for Mobile Application

Like all the other cool kids, we at Soluto have a mobile app and a lot of micro-services that this app utilizes. Recently, we added a feature to our app that required sensitive user data, and for this feature we had to add some sort of authentication between our app and the services it utilizes. Usually, this problem is pretty simple to solve: Just add social login to the app, and use those credentials to authenticate the requests. This solution…

Size matters: how I used React Native to make my app look great on every device

Every example on this post can be found here. Have you ever had your designer hand you a cool design for your React Native app that you developed on, say, an iPhone 7 – and when you try to run it on a tablet, it looks like it was left in the dryer for too long? That’s probably because the design was created using pixels whereas all dimensions in React Native are unitless, represented by “dp” (density-independent pixels). Simply put…

Testing for dummies Product Managers

Bugs – we all hate them One of your team’s features has a bug, again… You either can’t learn what you hoped to from this feature (is the feature working as we expected it to work? Do users like our new feature?), or does it cause a bad user experience? Best case it’s annoying, worst case it costs you time and money. Now you have to navigate rough waters with customers, and fix the issue instead of moving forward to…

How Fastlane Saved Us from Deployment Hell

At Soluto, we’ve created a platform that we provide to different mobile phone carriers and service providers. It’s only one codebase, but it gives each partner their own “flavor” of the app by allowing them to control the color palette, assets, and other features to their liking. The thing is, to develop, test, and deploy this kind of app, we need the ability to use multiple deployment platforms and support multiple build configurations for each “flavor” of the app. And…
