rob-olmos··on Air Purifiers as White Noise Machines
Alrighty, don't a lot of people already do this? Sometimes I'll do both an air purifier white noise and some music or something from myNoise
rob-olmos··on I Found a $90k Remote Code Execution Vulnerability in Google
You might be putting too much dish washer detergent
rob-olmos··on JDK 28
I'm curious what about Java concurrency hasn't made sense or not clicked? Also in comparison to other languages like Erlang or just in general?
rob-olmos··on We just shipped support for the ugliest part of HTTP: Vary
"If the origin response does not include a Vary header, Cloudflare caches the response normally"[1]

"If one response omits it, Cloudflare could cache that response without the variance needed to keep it isolated."[2]

Will that non-Vary cache object front-run any Vary-segmented cache objects?

If so, probably worth adding a snippet rule to ensure every response has a Vary header?

I took their point to be about wifi being jammable

Lifestreams was also an interesting take on a desktop UI back in the day
rob-olmos··on Bucketsquatting is finally dead
Is the AWS account phone number also their phone and not the business/corp phone? And you tried the dedicated lost MFA device form?
rob-olmos··on Copilot Chat in VS Code is now open source
"- cursor position marked as ${CURSOR_TAG}: Indicates where the developer's cursor is currently located, which can be crucial for understanding what part of the code they are focusing on."

I was not aware that was a thing and useful to know. Thanks!

rob-olmos··on Open-sourcing circuit tracing tools
Anthropic employees Sholto Douglas & Trenton Bricken did an interview recently with Dwarkesh Patel, pieces here and there was about the circuit tracing insights.

https://www.dwarkesh.com/p/sholto-trenton-2 -- search the transcript for "circuit" for the quick bits.

Eg, "If you look at the circuit, you can see that it's not actually doing any of the math, it's paying attention to that you think the answer's four and then it's reasoning backwards about how it can manipulate the intermediate computation to give you an answer of four."

rob-olmos··on AI Will Upend a Basic Assumption About How Companies Are Organized
Adding to the GP & sibling: Even in Los Angeles with some of the bigger libraries the IT/programming books were on the older (outdated?) side.. The more modern material was at the book stores like Barnes, Borders, or another one at the mall (I don't remember if it was B Dalton, Walden, or something else).. thankfully I could skateboard there after school or work and read them there for the evening since I couldn't afford them. Getting the internet and SNR of content back then was a game changer to me too.
rob-olmos··on AI Demos by Meta
Ahh I see. Thanks for the info!
rob-olmos··on AI Demos
Is this subject purposely spelled Aidemos somewhere like the HN title says instead of AI Demos?
rob-olmos··on 2400 phone providers may be shut down by the FCC for failing to stop robocalls
Thanks for linking the list! I'm seeing "Sangoma U.S., Inc." in it, which might apply to quite a few people & companies.
rob-olmos··on Willow, Our Quantum Chip
Reminder to anyone if DKIM keys haven't been rotated in a while they might still be 1024. Eg., Google Workspace but new keys are 2048 now.
rob-olmos··on Functional PHP (2015)
Since php 7.4 there's been opcache preload to keep a lot of the framework instantiated, in php 8.1 opcache inheritance cache covered some ground with preload.

Some frameworks like symfony considered removing preload support but they were still seeing benchmarks of 10% better performance with it so it was kept.

The biggest pain point with preload IMO is it's global, not per pool, and php-fpm needs to be restarted to update the preload script.

rob-olmos··on When Bacteria Are Beautiful
Relatedly the movie "The Fountain" they combined chemicals and bacteria to create some of the visual effects instead of CG. The DVD has an extra of "Peter Parks Bonus - Macro Photography Loop".
rob-olmos··on Deploying Web Apps with Caddy: A Beginner's Guide Caddy
Recent question I haven't look much into yet: Is there a way to limit the number of simultaneous http2/3 streams from an IP address with Caddy?

rob-olmos··on Starlink Direct to Cell
I'm thinking the same.. if I've fallen off a cliff or crashed my bike and broken my leg, possibly in shock too, I want something rugged & simple to activate like a PLB
rob-olmos··on Learn and Test DMARC
Dunno why you're being downvoted, you're correct that it's only "or".
rob-olmos··on Smashing the state machine: the true potential of web race conditions
Post on ACIDRain as an example of the ecomm time-gap issue back in the day: https://news.ycombinator.com/item?id=20027532
rob-olmos··on Nginx Unit – Universal web app server
Another example is API Platform's docker setup:

Volume config: https://github.com/api-platform/api-platform/blob/main/docke...

Caddy config: https://github.com/api-platform/api-platform/blob/main/api/d...

php-fpm config: https://github.com/api-platform/api-platform/blob/main/api/d...

I'm also curious on the performance differences between containers.

rob-olmos··on We replaced Firecracker with QEMU
Tweeted Sep 21, 2010, might still be true for EC2 VMs though.

rob-olmos··on Web Apps on macOS Sonoma 14 Beta
It would be nice for web apps to have a setting users (not only the developers) can enable that will allow closing the app's window without quitting the app, like a lot of native desktop apps behave (eg, Safari).
rob-olmos··on Connect() – a new API for creating TCP sockets from Cloudflare Workers
WS = WebSocket? I think integrating with the Discord API would've been one use case until they added the slash commands & webhooks.

But looks like Discord Gateway blocks CF Workers: https://github.com/discord/discord-api-docs/issues/6145#issu...

rob-olmos··on Google Cloud Workstations managed development environment is now GA
Maybe just me but the cloud desktops pricing still isn't all that attractive for some businesses to make a big shift to using them, but also not terrible for some businesses that could use the extra security or cloud environment benefits:

8hrs per workday for a 4 vCPU and 16 GB RAM = $217.36 per month[1]

rob-olmos··on The cloud backlash has begun: Why big data is pulling compute back on premises
In addition to the other comments, after it's up & running some colos will also offer "remote hands" assistance, like replacing a failed drive. In that case ideally the enclosure will or can be made to make that slot's LED red or something so they know exactly which drive to pull.
