pjjpo··on GrapheneOS has fixed the Android 17 QPR1 kernel performance regression
Thanks for the explanation! Wow releasing regressions only for older devices, that's something.

GrapheneOS looks really good thanks for working on it. Unfortunately Google Pay is critical for me and it's unfortunate Google is gatekeeping that, but I will look on jealously.

pjjpo··on GrapheneOS has fixed the Android 17 QPR1 kernel performance regression
I had assumed this was just Google effectively "ending support" for my 9a by forcing some AI thing into my lowish RAM. I can't believe even the latest Pixel users are having this problem since I thought they actually QA those.

Sorry but at this point, for me it is shame on every Googler for continuing at a company that has absolutely no interest in user experience anymore. It's on you, directly or indirectly.

pjjpo··on Sonnet 5.5
Smart people delegate to dumb people. Of course ideally dumb people get slightly smarter. From my experience sonnet is mostly for opus or fable to delegate to. So delegates getting more useful is always a good thing.

Seeing 2000 years of history being replayed by the AI startups is pretty weird right?

pjjpo··on OpenAI Says It Will Not Release Newest A.I. Model Over Safety Concerns
I noticed Sol seems to get rate limited enough to get pretty annoying now. Same for me with every model release that isn't really better than the last, leaving the old model doesn't mean much when they start shifting over capacity.
pjjpo··on Japan moves to tighten rules for foreigners
This is a government that needs anything to distract from its failures indeed. But that's not changing unfortunately - given there seems to be no real direction to fix the economy that is currently in a gutter, I think it's pragmatic to restrict immigration. Crime is skyrocketing, both Japanese and immigrants - even the Yakuza are getting into scam operations on Katagi, i.e. normal people. This basically never happened before and is a turning point. It's what happens in a bad economy and will just continue to get worse.

Low wage immigrants will not be able to fix the economy (demographics related decline is still decades away, yes it is important long term but not if the fundamentals don't improve). They will increase crime though since that's just what happens when you are poor in a bad economy. There won't be culling of poor locals but restricting inpu where possible, immigration, seems ok given the overall picture.

pjjpo··on Wall Street is growing skeptical of the data center boom
While it seems there are other examples in the article, still, leading with Wall State is skeptical of SoftBank doesn't make the point land very hard.
pjjpo··on Pandas Should Go Extinct
Liked the title
pjjpo··on I resigned from Anthropic today
If I were Anthropic I would sue him for slander to get the equity back. Then, he may actually return it. Or he may go to court, which would be revealing...
pjjpo··on Asahi Linux on M3
I would like to have a great laptop running Linux but the hardware options are just not there.

So I end up with a MacBook with macOS. Some may refuse to do that but I expect that's only a tiny missed opportunity.

pjjpo··on Ganon's Mysterious Origins (Revisited)
The article starts by calling Kamen Rider, Power Rangers. Before that it said something about posts taking a long time due to research.

Didn't read the rest but did skim through that crab bat pic wondering what that was, didn't realize it's Ganon!

pjjpo··on The creator of Jujutsu has joined ERSC
Funny how the threads are all about jj. Personally the move to a startup focused on version control, to me an obvious sinking ship, is more interesting. Not spectrum though.
pjjpo··on Chrome again exempts Google from user site data settings
Here's a link in case it's needed (I suspect most people that assume all of their problems are because of the administration don't actually read links but maybe if it's from their court?)

pjjpo··on Python's pre-declared constants are kinda weird
Relatively new, scripts can define dependency metadata now adays to achieve that to some degree. Any pip style versioning including an exact match works there.

pjjpo··on Malicious Rust crate Arrayref runs a build-time payload
I recently found a rust library that downloads and runs Bazel transparently.

Lost a lot of faith in the safety of the Rust ecosystem...

pjjpo··on Slack Code
It's always amazing to me how everyone continues to pay a fairly ridiculous price for Slack. Sure it has it's issues but I think people would get used to it and be just as productive with the free Google Chat they already have if any executive had the guts to say they're not going to waste money on Slack anymore. But never happens.
pjjpo··on Protobuf has LSP support. You're welcome
Comparing a wrapped C++ gRPC backed stack with an httpx/requests backed one is like comparing apples to elephants.
pjjpo··on Nvidia dramatically reduces amount of OpenAI infra financing it may guarantee
SoftBank has always managed to squeeze by after every mistake selling some early huge wins Alibaba, Nvidia, arm. Wonder if they still have any of those left in the back pocket.
pjjpo··on U.S. debt-to-GDP ratio reaches 123%
And the other half thinks you can raise taxes and grow revenues while keeping the loopholes for their elites.

The only thing intentional in politics is preserving your personal status and wealth. This is bipartisan.

pjjpo··on I regret migrating to Codeberg
I have seen so much governance weirdness from Codeberg over the years that it isn't even on the radar to migrate to. GitHub has gotten less stable, I wouldn't mind an alternative, but Codeberg just wouldn't ever be that. To be fair I am just on the sidelines seeing net commentary so it may not be a fair take but it doesn't change that point.

Do people know Codeberg well and migrate to it anyways, or they just don't know? If the former, wondering what gets you to that point.

pjjpo··on The Corporate Creep of Plex: Why it may be time to move to Jellyfin
I think anyone grandfathered in to a lifetime license is getting a pretty good deal on this. Mine was $119 in 2017. The only other lifetime license I have bought is Adguard, also excellent. Software that gets unlimited updates for a low price is _very rare_ right? If there are other good examples, happy to hear them!

I get that things are changing with Plex, naturally given it was a steal. But somehow it feels in bad faith when the author got that great deal but puts out this hit piece.

pjjpo··on Buz – A fork of Bun using modern Zig, with sub-1s incremental builds
I maybe am reading too much into this, but it's weird to me that a zig lead would be posting about an AI-only project despite zig's stance on AI. Maybe zig's official stance isn't that well supported in their own community.
pjjpo··on SPCX is now Wall Street's most shorted new stock
I think I follow this and most people probably also understand what it is that causes a bank default (i.e. everyone withdraws their money simultaneously). Still trying to dig at the mapping.

IIUC the main difference with stock is the market prices the items by demand unlike where the treasury effectively prices the items by supply and banks work under that. So the stocks are expected to always be liquid potentially at a lower price while banks have to be bailed out by the government for liquidity if a bank run. This definitely feels different, though I guess the extreme case gets closer, if every single bank needs to be bailed out at once, the currency price will go down like stocks do.

pjjpo··on Ask HN: Is it just me, or is software buggier across the board?
While I don't want to ruin this thread with coming out, I can't find a better place - sorry.

While I have a guess on what elephant everyone is thinking about, I wonder if it's just the stock market - at a higher level capitalism itself. I have felt Android get less stable with pretty much every release for many years now, well before the current boom. I think this is all a long term trend devaluing craftsmanship, with a root cause of why care if you can still make tons of money anyways.

pjjpo··on Java 27: What's New?
Wait, what's Java 11?
pjjpo··on Apple to increase spend with Broadcom to produce billions more U.S. chips
If Broadcom could filter out FBAR for me would happily buy some stock.

pjjpo··on Rewriting Bun in Rust
I have found LLMs struggle with Rust's constraints - they are optimized to produce code that passes the tests, not necessarily good code. So instead of working out lifetimes and borrowing, it will be happy to copy a buffer many times without thought. This means I have to still go through line by line to review and often rewrite either by hand or with another LLM iteration.

There may be some prompting that can help with this but I suspect there is a fundamental tension between writing working code vs good code in LLMs. Go is popular for being simple, making it easy to jump in and write something fast and stable - minimizing the gap between working and good code probably helps out the LLMs a lot.

pjjpo··on The Reports of Jim Carrey's Death Are a Failure Mode
I notice Gemini is essentially a frontend to Reddit at this point. I'm guessing that was on TikTok and also Reddit, while the malicious Wikipedia edit doesn't make it through a subreddit.

Too much muscle memory to change yet but I continue to want to at least try changing my default search engine to Reddit Answers for a trial to see how it compares to Google, probably at least as good.

pjjpo··on Bun has an open PR adding shared-memory threads to JavaScriptCore
I think this is precisely why I don't mind it that much. I can't audit a huge codebase like a JavaScript runtime, whether the code is by a human from scratch or not. I just have to trust it as a black box.

I've seen LLMs produce terrible code indeed, but I have also seen humans produce terrible code. I haven't dug in to JS runtimes specifically but have read plenty of code in openjdk and cpython - there are many points that could be done better, but there's also no point since it's working, and keeping working code unchanged tends to be a smart decision in software engineering.

So of course the last point brings up whether it was a good idea to rewrite bun if it was working. Apparently the bun team thought the difficulty in getting changes in zig upstream meant it is. I don't intend to hold LLM code to a higher bar than human code - notably if the runtime continues to work, that is as good as I can expect from what is otherwise a huge black box of extreme programming (not that agile kind).

pjjpo··on Tesla allegedly in autopilot mode crashes into Texas house, woman killed
I agree with the sentiment and don't like Elon at all. But I think there is a case to say the Full refers to features, so not only lane change / parking, but actual driving fully. If it said Perfect FSD or even High Quality FSD, that's definitely worse, but we have to acknowledge FSD can fully drive in many cases, not enough for me to be comfortable enough maybe, but comparing to rat poison seems like a stretch.
pjjpo··on Iran Delays U.S. Peace Talks over Israeli Attacks in Lebanon
If the latter is no, I do hope the US finally ends military aid to Israel. I really doubt it will happen, but if the record says it should be ok, then that would be really great.
