The software engineering compensation market becoming trimodal - split into three distinct groups that "spike" and that have little overlaps.  Most engineers are not aware of this third, Big Tech pillar and the compensation ranges it introduces, assuming compensation can not go beyond what is offered at the second pillar:  Read more about salary tier strategies and competable compensations: The Pragmatic Engineer

"Netflix is considering the following leveling system" - Engineer 1 - Engineer 2 - Senior - Staff - Principal The details of the system are still being worked out, and a proposal has been circulated within engineering. The proposal, understandably, has resulted in lots of questions, especially around whether existing engineers will be getting Staff or Principal titles. The original proposal made it seem that everyone would stay Senior, and with promotions, they could get to the next levels. Read more about the history and background: The Pragmatic Engineer

Nir Eyal explores how applying the Hooked Model drives customer retention and engagement by fostering good habits Trigger. An event that encourages someone to act, which is either an: External trigger: something in the environment — a ping, a ding, or a ring — that alerts a person to do something. Internal trigger: the desire to escape from an uncomfortable emotional state. Action. A behavior that anticipates a reward — opening an app, scrolling a feed, checking a dashboard, or playing a video. The simpler the behavior is to accomplish, the more likely the user is to do it. Reward. The user gets what they came for. Investment. The user puts something back into the product that makes it better the next time they use it. https://www.amazon.de/Hooked-How-Build-Habit-Forming-Products/dp/0241184835

 iOS Privacy: Instagram and Facebook can track anything you do on any website in their in-app browser The iOS Instagram and Facebook app render all third party links and ads within their app using a custom in-app browser. This causes various risks for the user, with the host app being able to track every single interaction with external websites, from all form inputs like passwords and addresses, to every single tap.

GitLab These are the expected behaviours of Engineers at GitLab. Most engineers at GitLab are Intermediate or Senior, so the priority is to address these levels first. Moving between levels, you should see that as engineers advance in their careers, their duties should encompass a higher degree of complexity, the scope of their influence should expand, and their contributions should become more impactful. These behaviors should not be considered as a checklist for promotion. Excellent Engineers may struggle with one or two aspects of their job and their strengths in certain areas should make up for deficits in others. However, it is important to show a significant number of strengths to be considered for promotion. Each of these behaviors should be achievable inside of normal working hours. If you feel that you need to work additional hours to be successful in your role you should talk to your manager. Junior engineers are still included on this framework even though we are not activel...

Enabling Optimizations Whole Module Optimizations (WMO) Reducing Dynamic Dispatch Dynamic Dispatch Advice: Use 'final' when you know the declaration does not need to be overridden Advice: Use 'private' and 'fileprivate' when declaration does not need to be accessed outside of file Advice: If WMO is enabled, use 'internal' when a declaration does not need to be accessed outside of module Using Container Types Efficiently Advice: Use value types in Array Advice: Use ContiguousArray with reference types when NSArray bridging is unnecessary Advice: Use inplace mutation instead of object-reassignment Wrapping operations Advice: Use wrapping integer arithmetic when you can prove that overflow cannot occur Generics Advice: Put generic declarations in the same module where they are used The cost of large Swift values Advice: Use copy-on-write semantics for large values Unsafe code Advice: Use unmanaged references to avoid reference counting overhead Protocols Ad...

Some good points: 4. Best code is no code - less code to maintain 6. Sometimes you just have to get started 9. Nobody asks enough about “Why” 11. One of the biggest differences between junior and senior devs is the latter have a well founded, dedicated opionen about tools, with the skill to come to an agreement with others what to use in which context 17.

I would add: Having a vision helps to at least roughly steer all activities in the right direction. It needs to be accepted that the vision might change and steering will be adopted!

  Nice blog post about staff (or engineering manager) archetypes: Staff Engineer: Leadership beyond the management track The Tech Lead guides the approach and execution of a particular team. They partner closely with a single manager, but sometimes they partner with two or three managers within a focused area. Some companies also have a Tech Lead Manager role, which is similar to the Tech Lead archetype but exists on the engineering manager ladder and includes people management responsibilities. The Architect is responsible for the direction, quality, and approach within a critical area. They combine in-depth knowledge of technical constraints, user needs, and organization level leadership. The Solver digs deep into arbitrarily complex problems and finds an appropriate path forward. Some focus on a given area for long periods. Others bounce from hotspot to hotspot as guided by organizational leadership. The Right Hand extends an executive's attention, borrowing their scope and ...

Architecture is a tough problem and there’s no shortage of articles, videos and open source projects attempting to solve the problem once and for all. In this collection we systematically develop an architecture from first principles, with an eye on building something that is composable, modular, testable, and more.

Firebase Remote Config is a great tool to enable dynamic config, feature toggles or even A/B testing with your native apps. Only thing you need to keep in mind that default update rate is 12h, but there is an official workaround for that for emergency use cases, trying avoid to exceed the quota ( Propagate Remote Config updates in real time ). Now Google took it a step further, allowing automatic personalization via Firebase Remote Config! Last but not least, we’re putting the finishing touches on a new feature of Remote Config, called personalization. Personalization will give you the ability to automatically optimize individual user experiences to maximize the objectives you care about - such as revenue or engagement - through the power of machine learning. After a simple setup, personalization will continuously find and apply the right app configuration for each user to produce the best outcome, taking the load off of you. If you want an early look at this feature and to try it out ...

The Matrix This 2x2 matrix low effort vs. high effort high value vs. low value is a nice and easy consumable visualization model. The Weights Suggested weights are Reach How many customers does the feature impact? Customers New/existing target groups Revenue Will it drive revenue either direct or via extended CLV? Acquisition Will the feature help drive new customers? Efficiency Does the feature help drive efficiency in customers’ lives – be that internal customers (colleagues), or external (paying) customers? Brand Does the feature enhance your brand awareness? The classification/quadrants Top left to bottom right Q1 Do it now!
