zlatkov··on Ask HN: My dev blog has 11k followers. I stopped writing it. What would you do?
I actually don't think there could be meaningful offers for a blog of that scale.
zlatkov··on Ask HN: My dev blog has 11k followers. I stopped writing it. What would you do?
Yes, it was actually what got us the initial waves of high volume/quality signups to our product, so it was indeed important for the company.
zlatkov··on Ask HN: My dev blog has 11k followers. I stopped writing it. What would you do?
Good advice, and you're right that people deserve it. I never did it because I never formally decided to stop. I just assumed there'd be some form of continuity...
zlatkov··on Deep Dive into G-Eval: How LLMs Evaluate Themselves
That's true. Even small API or model version updates can shift evaluation behavior. G-Eval helps reduce that variance, but it doesn’t eliminate it completely. I think long-term stability will probably require some combination of fixed reference models and calibration datasets.
zlatkov··on Deep Dive into G-Eval: How LLMs Evaluate Themselves
I haven’t come across any research showing that a specific LLM consistently outperforms others for this. It generally works best with strong reasoning models that produce consistent outputs.

zlatkov··on How JavaScript works: the rendering engine and tips to optimize its performance
I'm very happy to hear that!

If you have any feedback or need assistance, you can always reach me at alex@sessionstack.com or ping us in our live chat inside the product :)

zlatkov··on How JavaScript works: the rendering engine and tips to optimize its performance
To explain just briefly, SessionStack is just collecting events from the browser like user interactions, DOM changes, etc. and then tech info like crashes, network, debug messages. All of this data is being batched in memory and sent to our servers every few seconds. And that's all the work that we do on the client-side, almost the same as any analytics tool that you already use. The "magic" happens on our end, where we're reconstructing all of this data, pulling the needed static resources, etc. in order to recreate the same series of events as they happened to your users and show you that information visually. And this happens in real-time.

zlatkov··on Show HN: Video reporting of problems directly in your web app
Hey, guys! One of the developers behind SessionStack here. Looking for some feedback about the idea of allowing users to record problems directly in web apps instead of filling up forms, attaching screenshots or doing remote desktop sessions with the support team. During the recording of the problem, all unhandled JavaScript errors are being logged with the corresponding stack traces to provide additional context.

Hi there. I'm the Co-founder of SessionStack - https://www.sessionstack.com/ . Seems like you're developing quite the same tool (we're not open source, but have an on-premises version).

It's quite an interesting space so I wish you good luck in your endeavor.
