This is an OPML version of the HN Popularity Contest results for 2025, for importing into RSS feed readers.
Plug: if you want to find content related to your interests from thousands of obscure blogs and noisy sources like HN Newest, check out Scour. It's a free, personalized content feed I work on where you define your interests in your own words and it ranks content based on how closely related it is to those topics.

Disclaimer (May 2026). Sorry for the long radio silence on the comments, busy stretch on my side. I no longer use this setup and stopped tracking it actively. I'm refreshing the page out of thoroughness because comments kept coming in and people deserve an honest snapshot. If you find better workarounds, post them in the comments and I'll link them, but I won't be maintaining this further.
Codex deprecated wire_api = "chat" in favour of OpenAI's Responses API. DeepSeek only speaks Chat Completions, so the direct integration documented below is no longer reliable. Symptoms reported by users:
An assistant message with 'tool_calls' must be followed by tool messages... (insufficient tool messages following tool_calls)Missing 'reasoning_content' field in the assistant message at message index NMost application security practitioners are familiar with Unicode XSS, which typically arises from the Unicode character fullwidth-less-than-sign. It’s not a common vulnerability but does occasionally appear in applications that otherwise have good XSS protection. In this blog I describe another variant of Unicode XSS that I have identified, using combining characters. I’ve not observed this in the wild, so it’s primarily of theoretical concern. But the scenario is not entirely implausible and I’ve not otherwise seen this technique discussed, so I hope this is useful.
Lab: https://4t64ubva.xssy.uk/
A quick investigation of the lab shows that it is echoing the name parameter, and performing HTML escaping:
Learn how to send emails through Gmail SMTP with Cloudflare Email Routing in this comprehensive guide.
To proceed with this method, ensure that you have enabled two-factor authentication for your Google account. If you haven't done so already, you can follow the link to set it up → Enable 2FA in your Google account.
There exists a vulnerability in exception sanitization of vm2 for versions up to 3.9.16, allowing attackers to raise an unsanitized host exception inside handleException() which can be used to escape the sandbox and run arbitrary code in host context.
The challenge was to achieve RCE with this file:
<?php ($_GET['action'] ?? 'read' ) === 'read' ? readfile($_GET['file'] ?? 'index.php') : include_once($_GET['file'] ?? 'index.php');Some additional hardening was applied to the php installation to make sure that previously known solutions wouldn't work (for further information read this writeup from the challenge author).
I didn't solve the challenge during the competition - here is a writeup from someone who did - but since the idea I had differed from the techniques used in the published writeups I read (and I thought it was cool :D), here is my approach.
