its-summertime··on Show HN: Lathoa, a math app for kids where the AI is wrong on purpose
I think speed would be irrelevant, or perhaps would discourage deep engagement with the problems.

I think presenting it as AI can be wrong is not as valuable as presenting it as developing the ability to question what one is told. (e.g. Verizon Math)

its-summertime··on Nvidia wants to put a watchdog chip next to every AI agent
Every major AI company already has a mirror of the wider web, and they have already started using that. Its already a solved problem except for the seemingly extreme desire they all have to not use firewalls
its-summertime··on We have a year to fix security everywhere
I guess the year mark is when things go from bad to worse? Instead of the financially motivated groups currently doing their work, it ends up being random people being able to say "Hack my ex's website" to a box they just bought and ran a program they downloaded onto it.
its-summertime··on Intellectual Fly Is Open (2025)
Personally I wouldn't be writing an open letter to what is effectively a bunch of spam bots. I don't think they'll read it, or care.
its-summertime··on 1Password Replied to My Disappointment
Was Guido designing Python for only his own sake, during his time as BDFL? As far as I know, he was not doing that.

Additionally, Guido never had exclusive control over the Python Software Foundation, from what I can see.

If Guido was the only person responsible for the Python Software Foundation, its only board member, its only share holder that the board is responsible to, and was designing Python for the use-case of a single person, himself, and he was soliciting donations, then yes I would consider those donations to effectively be a contribution to an individual. Of course I would.

> Our contribution is made to the Omacom Foundation, not to an individual

However, from DHH:

> Before this can be an amazing system for everyone, it first has to be an amazing system for me, personally.

By DHH's own words, all money currently is 100% spent on DHH's desires. That is a contribution to an individual.

its-summertime··on GrapheneOS project: pixel 11 no longer supports hardware memory tagging (MTE)
Oh that is very exciting to hear!
its-summertime··on GrapheneOS project: pixel 11 no longer supports hardware memory tagging (MTE)
As far as I know, only Motorola is given access to the driver source code for all the chips, which then as part of using it, they are obligated to release it, which then GrapheneOS can then access and use it.

As a result, Motorola's software support is just as important as Motorola's hardware

its-summertime··on We found a division by zero bug in FFmpeg with a vibecoded fuzzer
For those with difficulty accessing:

- - -

From: Anthony Hurtado <[redacted since hn has no scrape protection]>

vpk_read_packet() divides vpk->last_block_size and (par->block_align - vpk->last_block_size) by par->ch_layout.nb_channels without checking for zero.

While vpk_read_header() validates nb_channels > 0, the codec parameters may become zero through format probing misidentification (VPK probe score is 2/3 of AVPROBE_SCORE_MAX) or codec parameter reset, causing SIGFPE.

Fix by:

- Checking nb_channels != 0 before division in vpk_read_packet

- Returning EOF for empty last blocks (last_block_size == 0)

- Validating block_count > 0 in vpk_read_header

- Validating last_block_size <= block_align in vpk_read_header

Found by fuzzing with libFuzzer + AddressSanitizer. Reproduces with 10 distinct inputs.

[patch redacted for brevity]

its-summertime··on Mechanical Turk shutting down September 30
There is training systems and validation of skills in mturk iirc: for tshirt folding, you'd be given fake setups to be able to get used to controlling the robot, if you can't do it, you won't ever get assignments to do it. For traffic overrides, you'd be tested on having correct knowledge, and once again given supervised tasks to show you can actually be trusted (and there would be safety systems, elevating tasks that can't be performed at your level to people who can, etc)

The worker needs to do a bunch to opt into any given work group, which makes the (lack of) payments extremely unreasonable on top of everything else

its-summertime··on VMs won't contain cyber-capable agents
> but rather that we need to focus on finding and fixing vulnerabilities and misconfigurations in these environments.

And how long will that take? It's already well past due.

its-summertime··on IPFS Maintainers Winding Down
Protocol Labs owned significant parts of the infrastructure. Regardless of community support, PL leaving would always be damaging.
its-summertime··on IPFS Maintainers Winding Down
Kubo, Helia, Boxo, Rainbow, IPFS Desktop, IPFS Companion, Someguy, Service Worker Gateway, IPFS Check, libp2p, ipfs.io, dweb.link, check.ipfs.network, delegated-ipfs.dev, Wikipedia-on-IPFS.

It kinda feels like the AWS or Azure of file distribution, so much stuff so confusing. Also apparently with Protocol Labs owning several of those things despite not operating those things?

Ironically seems quite a fragile setup.

Regardless, very sad news.

its-summertime··on Why can't you combine .tar.gz files with cat?

    tar -c x | head -qc $((18*-512)) | gzip > x.tar.gz
    tar -c y | head -qc $((18*-512)) | gzip > y.tar.gz
    cat {x,y}.tar.gz | gzip -d | tar --list

seems easier to just not have the EOF marker, if you need to append stuff later
its-summertime··on Suicide hotlines don't seem to help
The title doesn't match the paper, which is about the results of improving the pre-existing hotlines setup, not about implementing a hotline or not.

This incorrect conclusion is directly called out in the paper:

> These estimates should be interpreted with a few limitations in mind. First, because 988 was implemented nationally, the design estimates the effects of greater exposure to 988-related local capacity expansion, not the total national effect of 988 relative to no crisis line.

its-summertime··on AI;DR (AI; Didn't Read)
Imagine a future where 99% of text is written by 1 unpassionate person. Reading the same patterns, the same tropes, the same flow across paragraphs, over and over, would be unpleasant. It already is unpleasant.
its-summertime··on Anthropic's ‘watermark’ text adulteration in Claude is a perversion of writing
> My error was believing Anthropic that their system wouldn’t adulterate and corrupt the semantics of the text their models generate.

Has that ever been the case? Are they not actively tweaking their models, their fine tuning, the system prompts, the tool definitions and implementations, the guard rails, tool calls, instant responses. There are hundreds of knobs that they can change daily, or between each prompt, or even half way through a generation.

its-summertime··on Show HN: Silent Shark – tactical map-based WWII submarine sim
If AI is used for the code, why isn't it disclosed? Or did Valve remove the disclosure?
its-summertime··on Stealing Reasoning Traces from Proprietary LLM APIs
We have its actual reasoning traces, and we have these psudotraces, distribution / nativeness is testable now
its-summertime··on Switching to electric stoves can dramatically cut indoor air pollution
It seems they considered water boiling in their numbers, which makes this estimation very non-portable across countries (e.g. countries where gas hobs are used, but also electric kettles are used)
its-summertime··on Switching to electric stoves can dramatically cut indoor air pollution (2025)
The paper: https://doi.org/10.1093/pnasnexus/pgaf341

The numbers:

[...]

We estimate average total residential long-term NO2 exposure across the United States to be ∼10 ppbv for people who own a gas stove (∼18 ppbv or more for households in the top 5% of gas burned while cooking) and ∼8 ppbv from total outdoor exposure for those with electric stoves, which cause no additional NO2 exposure.

[...]

Stratifying exposure by gas stove use intensity (i.e. by amount of gas burned while cooking, [...]), we find that people in households burning the 5th, 50th, and 95th percentiles of fuel nationally on average are exposed to 0.03 (95% CI: 0.01–0.07) ppbv, 1.7 (95% CI: 0.8–3.5) ppbv, and 10.3 (95% CI: 4.8–21.7) ppbv, respectively, of additional NO2 exposure from using their gas or propane stoves.

[...]

its-summertime··on LLMs reward expertise
Who's end state took / is going to take more tokens / money, however?

"LLMs reward expertise" is the title, not that "LLMs only make things possible for those with expertise"

its-summertime··on Can uBlock Origin Block WebRTC?
No it can't, but yes it can, just not like that.

https://github.com/gorhill/uBlock/wiki/Resources-Library#now...

As can be seen, it matches on the source, not the destination

https://github.com/gorhill/uBlock/wiki/Resources-Library#web...

can match on the destination, however.

Its not a good state of things, but I'm assuming its more of an issue on the browser side as opposed to the extension side

its-summertime··on Turn And Face The Strange
Filter bubbles and what not, but, googling the term only had Seinfeld show up on the bottom of the fourth page. Bottom of page 2 in a private tab.
its-summertime··on GDID Windows – Cut the tracker that follows you even under VPN
Using it correctly would not solve the issue at hand however.
its-summertime··on Turn And Face The Strange
I think the effect was less about it being correct or not, but instead more about if fly.io would treat humans as first class users compared to agents or not in the future.

The message is fine, but it was a weird choice to have it on fly.io instead of a personal blog

its-summertime··on Turn And Face The Strange
> Five of the most dangerous words in startups are “¿Por qué no los dos?”.

So are the prior products going to be shut down? If not, then when? if not when, then why not?

its-summertime··on Do I need to charge my toothbrush via my monitor?
Searching for something like "USB-C OTG slim" will help find up shims that can be stuck in the end of USB-A Male plugs to "convert" them to USB-C, and from my testing just now, seems to work for charging.
its-summertime··on Measuring Input Latency on Linux: X11 vs. Wayland, VRR, and DXVK
the statements of wayland being slow or not need a lot of context: what version of the game they played, the display server, the game settings, the display server settings, the monitor's feature set, the video card's feature set, the video card driver version, etc.
its-summertime··on Hideo Kojima afraid that 'digital data will no longer be owned by individuals' (2021)
