We introduce our first-generation reasoning models, DeepSeek-R1-Zero and DeepSeek-R1. DeepSeek-R1-Zero, a model trained via large-scale reinforcement learning (RL) without supervised fine-tuning (SFT) as a preliminary step, demonstrates remarkable reasoning ca…
A new way to handle dates and times is being added to JavaScript. Let's take a look at Temporal, what problems it solves, the current state, and what you'll find in the new documentation about it on MDN.
Imagine you’re running a restaurant. Every time a customer orders, you buy a brand-new frying pan, use it once, and toss it out. Sounds absurd, right? But that’s essentially what happens in EF Core when you create a new DbContext for every request. It’s wastef…

Welcome to another issue of Dev Leader Weekly! In this issue, I discuss how to take ownership as a software engineer.
Caltrain announced at its monthly Board of Directors meeting that regenerative braking on the new trains is generating and sending back to the electric grid approximately 23% of the energy consumed by the system.
What does it mean to "take ownership" with respect to projects? Let's discuss what this looks like in software engineering and how you can use this to level up as a developer! As with all livestreams, I'm looking forward to answering YOUR questions! So join m…
I'm Yasser and I've made it my mission to produce an alternative to LLVM, the current king of compiler backend libraries. I'm calling it Tilde (or TB for tilde backend) and the reasons are pretty simple, i believe it's far too slow at compiling and far too big…

When the topic of Rails performance comes up, it is commonplace to hear that the database is the bottleneck, so Rails applications are IO-bound anyway, hence Ruby performance doesn’t matter that much, and all you need is a healthy dose of concurrency to make y…
