Re:Ask HN: How would you prepare a tablet for an apocalypse on Tuesday November 03, 2026 @04:32AM (#50349857)
That's big enough for a Kiwix English Wikipedia snapshot, so I'd start with that. The Project Gutenberg epubs could keep you busy for a lifetime, so throw those on too. Some US Army field manuals might be good for basic survival instruction, though these are things you should practice before you're actually in a survival situation.

In this apocalypse scenario, I'm probably more worried about finding potable water and fending off scavengers than what's on my tablet though. It's a fun thought exercise, but not terribly practical. Buy paper books if you want something offline.

It’s use-after-free where the “use” is execution of arbitrary code. Yeah, that’s pretty bad.
Possibly related to the GCP London outage

No, the major number has no special significance to OpenBSD. 8.0 is just what comes after 7.9.

Apple Watch with cellular is effectively iPhone mini. There are 3d printable cases to make it into a bar phone.

Re:Searching for the Best Silicone USB Cable on Monday September 07, 2026 @04:34PM (#49602717)
Almost seems like it’d be easier to spend a couple weeks in Shenzhen getting cables made to your specifications rather than testing everything on the market.

Re:The Alpha 21264 CPU: NT's Greatest RISC (1998) on Sunday August 09, 2026 @06:48PM (#49237004)
The Alpha CPUs didn’t implement the div instruction and Linus’ assembly version was faster than DEC’s in some cases.

Don't these things get more efficient as they scale up? One big plant is probably better than 30 small ones.
I once saw a job candidate take a competing offer from Facebook because they had better snacks.
I came up with a color code based on the wiring: Red for Power Only, Blue for USB 2.0, Green for USB 3 (the ones with the extra pairs connected). I use paint pens to mark every cable I come across with this code. Generally speaking, only the Green ones have special PD emarker chips.

It doesn't cover every possible configuration, but it's good enough for when I'm like "I need a USB cable" vs "I need a good USB cable"

Re:AWS CloudFront Is Down on Thursday July 16, 2026 @06:23AM (#48932607)
Jul 16 3:18 AM PDT We continue working to resolve the increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Customers utilizing other origin types remain unaffected by this issue. Based on our investigation, we believe the root cause is related to a packet processing subsystem responsible for routing requests from CloudFront's edge locations to resources within customer VPCs. We continue to recommend that customers who are able to do so temporarily change their origin type to resolve the errors. We will provide another update by 4:15 AM PDT, or sooner if additional information becomes available.
They aren't actually shipping the new RP2350 silicon revision on Pico 2 boards yet. If you want the errata fixes, you've gotta source the chips and make your own boards.
I toured a sorting facility in Seattle recently. They said the only really profitable output is aluminum, everything else costs more than virgin material.

Tell Claude that it’s a Culture Mind. Entertaining for a little while.
Sounds like an opportunity for the business school to do a seminar on forming an LLC and writing contracts.

If your container has setuid binaries and these modules are loaded, yes.

Nevermind, I misread their HTTPS proxy documentation. Cloud is fine.

Have we already forgotten about the NSA's "SSL added and removed here! :)" slide that Snowden showed us?

I learned HTML/CSS from a book on a computer with no internet access. Seemed reasonable at the time but in hindsight was absolutely ridiculous.
imo, the real value of Ada/SPARK today is that it enforces a clear split between specification and implementation, which is exactly what your LLM needs.

You define the interface, types, pre/post conditions you want in .ads file, then let the agent loose writing the .adb body file. The language’s focus on readability means your agent has no problem reading and cross referencing specs. The compiler and proof tools verify the body implements the spec.

I’ve written some bit-banged serial drivers in Ada. It’s not exactly VHDL, but it rhymes.

Are they considering all uses of window.history.pushState to be hijacking? If so, why not remove that function from Chrome?

Re:Build web apps for smart glasses on Tuesday April 07, 2026 @04:33AM (#47672263)
I wasn't aware of these glasses, pretty cool. Not sure I'm ready to drop that much money on a pair with prescription lenses though.

Would be useful to have my multimeter display in my field of view when heads down debugging a circuit. There are a few bluetooth meters on the market, so I think this is doable?

Looking at the SDK, the fixed LVGL font is a bummer. Ideally I'd like to have a raw framebuffer to control, though I imagine this is difficult to do over bluetooth without blowing your power budget. Maybe you could have a custom indexed tilemap and push sprites around?
