Why am I receiving emails with a specific List-Unsubscribe header even though I never subscribed?

3 March 2026 @ 9:24 am

I'm receiving some marketing emails that contain a specific List-Unsubscribe header like this: I never subscribed to these emails. I'm trying to understand technically: How is my email address being associated with these unsubscribe links? Does the presence of List-Unsubscribe-Post: List-Unsubscribe=One-Click mean my address was programmatically added to a mailing system? Is this header automatically generated by common email platforms (e.g., SES, SendGrid, Mailchimp)? Could this be caused by list scraping or random address injection? Additional info: The emails pass SPF but fail DMARC alignment. The sending domain changes but the unsubscribe format looks similar. My address is not publicly listed anywhere. What is the technical mechanism behind this behavior?

Post-upgrade row count discrepancies in Vertica projections

3 March 2026 @ 8:41 am

I ran a VSQL query to capture the total row counts for each projection in a Vertica database before a version upgrade. After the upgrade, a few projections have different row counts than expected — some higher, some lower. The query I ran before and after the upgrade is as follows: SELECT schema_name, projection_name, SUM(total_row_count) total_rows FROM v_monitor.storage_containers WHERE projection_name <> 'c_license_metrics_super' GROUP BY schema_name, projection_name ORDER BY schema_name, projection_name

How to set a custom color for Nuxt UI UChip?

3 March 2026 @ 8:29 am

Given the Nuxt UI Chip component having a color property accepting fixed colors. I'm calculating a heatmap color ranging from the Tailwind colors "bg-transparent" to "bg-emerald-900" but how can I apply them? The color prop does not accept them and class="bg-emerald-900" sets the content background color. Is there a way to set the ui prop with that custom color? Given this sandbox This is not possible <UChip color="bg-emerald-900"> <UButton label="btn" /> </UChip> neither this <UChip c

Is putting tag hierarchally under a branch a bad idea?

3 March 2026 @ 8:24 am

I've seen that creating a branch hierarchical under another branch is not allowed, that is: > git branch foo > git branch foo/bar fatal: cannot lock ref 'refs/heads/foo/bar': 'refs/heads/foo' exists; cannot create 'refs/heads/foo/bar' But for tags it seem to be accepted at first glance: > git branch foo > git tag -m foo/bar foo/bar Is there any reason on shouldn't do that? I guess the question could be asked the other way around (ie put the branch under the tag), but to me it seems more logical to consider the tag under the branch (they're part of the branch IMHO).

Is this a reliable way to prevent bots from scraping emails?

2 March 2026 @ 6:10 pm

Is this a reliable way to prevent bots from scraping emails and sending spam, without having to resort to janky methods like images/actual text splitting? <p id="at" data-domain="email.com" data-user="test"/> <script> var element = document.getElementById('at'); element.innerHTML = '<a href="mailto:' + element.dataset.user + '@' + element.dataset.domain + '">' + element.dataset.user + '@' + element.dataset.domain + '</a>'; </script> Combining the elements together after the fact.

2026 Predictions: The Next Big Shifts in Web Accessibility

22 December 2025 @ 11:22 pm

I’ve lived long enough, and worked in accessibility long enough, to have honed a healthy skepticism when I hear about the Next Big Thing. I’ve seen lush website launches that look great, until I activate a screen reader. Yet, in spite of it all, accessibility does evolve, but quietly rather than dramatically. As I gaze […]

Up and Coming ARIA 

30 May 2025 @ 6:19 pm

If you work in web accessibility, you’ve probably spent a lot of time explaining and implementing the ARIA roles and attributes that have been around for years—things like aria-label, aria-labelledby, and role="dialog". But the ARIA landscape isn’t static. In fact, recent ARIA specifications (especially ARIA 1.3) include a number of emerging and lesser-known features that […]
