Speaker after speaker stressed development speed, including the ability to ship to mobile and desktop from the same React code. The implications for complexity-management and user-experience were somewhat less of a focus. As you might expect, putting 75% of the 3.5MB JS payload (15MB unzipped) in the critical path does unpleasant things to the user experience, but none of the dizzying array of tools involved in constructing bk.com steered this team away from user experience failure.

A metal fork drags its four prongs back and forth across the yolk of an over-easy egg. The lightly peppered fried whites that skin across the runny yolk give a little, straining under the weight of the prongs. The yolk bulges and puckers, and finally the fork flips to its sharp points, bears down on the yolk and rips it open, revealing the thick, bright cadmium-yellow liquid underneath. The fork dips into the yolk and rubs the viscous ovum all over the crispy white edges, smearing it around slowly, coating the prongs.

Everything is sexually suggestive now because on most platforms, for years, being sexually overt meant risking a ban. Not-coincidentally, being horny about everything is also one of the few ways to get engagement on those same platforms. At the same time, legislators are trying to make everything “pornographic” illegal or impossible to make or consume.

HTTP/1.1 (RFC2616 and onwards) remains the lowest common denominator that clients and servers need to support, and of course modern stacks will want to use HTTP/2 (RFC9113) and HTTP/3 (RFC9114), but just how do they determine each others’ capabilities and bootstrap their connection?

A hidden comment was enough to make GitLab Duo leak private source code and inject untrusted HTML into its responses. GitLab patched the issue, and we’ll walk you through the full attack chain — which demonstrates five vulnerabilities from the 2025 OWASP Top 10 for LLMs.

Granted, it’s a very blurry placeholder especially in contrast to other leading solutions. But the point is that it’s minimal and non-invasive! No need for wrapper elements or attributes with long strings of data, or JavaScript at all.

What have we done?

Go’s http.ResponseWriter writes directly to the socket, which can lead to subtle bugs like forgetting to set a status code or accidentally modifying headers too late.

Earlier this year, scientists discovered a peculiar term appearing in published papers: “vegetative electron microscopy”. This phrase, which sounds technical but is actually nonsense, has become a “digital fossil” – an error preserved and reinforced in artificial intelligence (AI) systems that is nearly impossible to remove from our knowledge repositories.

Apache ECharts provides more than 20 chart types available out of the box, along with a dozen components, and each of them can be arbitrarily combined to use.

An attacker within bluetooth range is able to trigger navigation to a FIDO:/ URI from an attacker controlled page on a mobile browser, allowing them to initiate a legitimate PassKeys authentication intent which will be received on the attacker’s device. This results in the attacker being able to “phish” PassKeys credentials, completely breaking this assumption that PassKeys are impossible to phish.

Critical authentication bypass vulnerabilities (CVE-2025-25291 + CVE-2025-25292) were discovered in ruby-saml up to version 1.17.0. In this blog post, we’ll shed light on how these vulnerabilities that rely on a parser differential were uncovered.

As shown once again: relying on two different parsers in a security context can be tricky and error-prone.

I spent the past few months building my personal website from the ground up, finally taking the time to incorporate some 3D work to showcase my shader and WebGL skills. Throughout this work, I got to truly understand the crucial role that post-processing plays in making a scene actually look good, which brought some resolutions to long-term frustrations I had with my past React Three Fiber and shader projects where my vision wouldn’t materialize regardless of the amount of work and care I was putting into them.

Taking the time to build, combine, and experiment with custom post-processing effects gave me an additional creative outlet, and among the many types I got to iterate on, I always had a particular affection for the several “retro” effects I came up with. With subtle details such as dithering, color quantization, or pixelization/CRT RGB cells, they bring a pleasant contrast between the modern web landscape and a long-gone era of technology we 90s/early 2000s kids are sometime longing for.

Implementations of the new JavaScript Temporal object are starting to be shipped in experimental releases of browsers. This is big news for web developers because working with dates and times in JavaScript will be hugely simplified and modernized.

I was pleasantly surprised by the results in Chromium browsers at medium and large container widths. Hyphenation seems conservative and readable, yet there are no unsightly gaps or “rivers” between words. Safari and Firefox hyphenate a bit more frequently, but not distractingly so.

California SB 976, “Protecting Our Kids from Social Media Addiction Act,” is one of the multitudinous laws that pretextually claim to protect kids online. Like many such laws nowadays, it’s a gish-gallop compendium of online censorship ideas: Age authentication! Parental consent! Overrides of publishers’ editorial decisions! Mandatory transparency!

NetChoice made a variation of my argument, saying that age authentication always acts as a speed bump for readers accessing desired content. The court says that’s not so. The court notes that “many companies now collect extensive data about users’ activity throughout the internet that allow them to develop comprehensive profiles of each user for targeted advertising” and, mining that data, age authentication could “run in the background” without requiring any affirmative steps from readers to complete the authentication.

I started running a basic link blog on this domain back in November 2003—publishing links (which I called “blogmarks”) with a title, URL, short snippet of commentary and a “via” link where appropriate. So far I’ve published 7,607 link blog posts and counting.

In April of this year I finally upgraded my link blog to support Markdown, allowing me to expand my link blog into something with a lot more room. The way I use my link blog has evolved substantially in the eight months since then. I’m going to describe the informal set of guidelines I’ve set myself for how I link blog, in the hope that it might encourage other people to give this a try themselves.

Deep technical analysis of the CONTINUATION Flood: a class of vulnerabilities within numerous HTTP/2 protocol implementations. In many cases, it poses a more severe threat compared to the Rapid Reset: a single machine (and in certain instances, a mere single TCP connection or a handful of frames) has the potential to disrupt server availability, with consequences ranging from server crashes to substantial performance degradation. Remarkably, requests that constitute an attack are not visible in HTTP access logs.

Shared dictionaries can supplement Brotli and ZStandard compression to deliver substantially higher compression ratios for websites that frequently ship updated code, and can—in some cases—deliver 90% or better compression ratios. This post goes into more detail on how shared dictionaries work, and how you can register for the origin trials to use them for Brotli and ZStandard on your website.
