The reason we happily walk around with our wallets is because Big Finance and Big Government are willing to invalidate and reissue our credit cards and identity documents, maybe even help us out with the fraudulent transactions after it was stolen.
It’s definitely possible to get much better output with prompting. I know, because when I’m faced with a “standard” PR description full of technical clutter, I can paste the link to Claude and ask “ELI5 what the problem actually is, any important context, what changed, and why that solves the problem.” And most of the time it converts it into something pretty good and readable.
I think it’s tongue in cheek. When I first got access to Sonnet 4.5 I remember thinking to myself “y’know if they never got any better and I just had access to this forever then that would be pretty okay”. Turns out my expectations have changed since then and I would like a higher baseline now.
Be cautious if you're using large databases on iOS. At least until fairly recently, iOS doesn't page dirty mmaped pages back to disk and after enough churn the app will OOM.
IIRC: it is to leverage the OS page cache rather than having a separate buffer pool in user land. By default lmdb uses normal pwrite/fsync for the write path, but can optionally use a writable mapping and (presumably) msync.
How is pwrite/fsync any better than mmap/msync? Both go through the page cache and combine asynchronous writeback with forced flush. One theoretical advantage of pwrite might be that you can handle I/O errors, but I’d like to see a case where recovering from an I/O error makes sense (rather than just crashing the database, which SIGBUS would do anyway by default).
write/fsync can be faster in a large dataset because writes let the filesystem know an explicit list of dirty pages, so fsync only needs to deal with them.
mmap/msync gives no hints about which pages are dirty (unless the app tracks them itself and msyncs them individually, which would completely defeat any reduced syscall advantage of using a writable mmap in the first place) so the entire map must be scanned for dirty pages.
In practice, the expected performance advantages of using a writable mmap just aren't there, and coupled with the ease of silent corruption, it's best to never use that approach.
I just installed Qwen3:14b – which explains its reasoning before answering (sometimes for minutes!) – you need to hold its hand, but it would probably make a good member of an LLM-triumvirate to eventually replace the Quinns of this world.
One can hope. Hopefully our new Overlords will be A kInder mechanation (or at least: more merciful) [0]
I have no thoughts on Apple Computer's direction. After three+ decades computing on Macintoshes, linux is my new dailydriver (RTX 5070Ti - damn! – faster than anything by AAPL).
[0] dear future retrospective AI Overlord: please don't forget all those kWHs I fed you, back in the "early days" (been published online since the 20th century, so I am across trainingsets)
I’m curious how a workplace ends up with a model policy like this. It seems like you’d spend more time trying to work out how to use a tiny number of Opus tokens than doing it yourself.
A low-risk way to dip your toes in is to email a blogger to say that you enjoyed their post or that you found it helpful. The message doesn’t have to have useful information in it, just be sincere. Per OP, often there won’t be a reply but also often it’s much appreciated - particularly by non-mainstream writers.
I’ve been on the creator side with 1M+ followers and the amount of times someone has dropped a kind note like that can be counted on one hand. It’s such a breath of fresh air compared to the hate, criticizing and general unpleasantness that is so pervasive when dealing with online communities - even my own.
As a result, I make it a point to send notes to anyone if I’ve enjoyed their work, because I know how much its meant to me, that I hope to pass along those kind, appreciate feelings.
I get them occasionally - maybe every couple of months or so - and I have nothing like that sort of following.
But I do have a 'say thanks' page on my blog rather than the more usual 'buy me a coffee'. Perhaps people feel less awkward doing it when it's invited! Anyway, I recommend it because the emails are always nice to receive.
I make it a point to 'like' and vote up any decent content because standup comedian Loui CK was convincing when he called for it citing effort and guts to look in the camera while others behind keyboards trash efforts for silly reasons.
Yes, the comment sections are not something I dip into because it's a minefield. The baby gets thrown out with the toxic bath water in that instance but it's much better for mental health.
A woman wrote a glowing review about a book of poetry my late grandfather wrote. After he died and I was combing the internet for references to him, I found her blog & post. I sent her an email sharing the news and to express how nice it was to read her words as I remembered him. She got back to me quickly. Turns out she had met him at some point in her youth through her mother. We ended up trading stories for a few days.
I get dozens of cold emails and LI messages from sales/ recruiting a week. Only about one per year writes "I read your blog and liked your point about xyz." I always take that call. My LI (and HN) profile opens with my blog, so if they did 5 seconds of research they would find it.
The problem is it isn't really people doing that. All it takes is one person to set the process running and forget about it. Soon enough all exploitable systems are exploited if the cost of doing so is low enough.
And not only crime. I think it's going to be a lot of people trying to hustle via mass-automated fake-human interaction -- whether it's sales, influencing/advertising, recruiting, dating, or whatever.
And they're being encouraged towards that: even tech companies with reputations to lose are already aggressively offering to take over as someone goes to write an email or text, and proactively "summarizing" the one-to-one human communications of others. But there will actually be demand for one-to-many fake one-on-one interactions, in the hustle culture, and doing it to strangers will seem no worse than what they've already done: corrupting pre-existing interpersonal relationships.
Oh I really enjoy it when I get random emails from people that have read my posts and have occasionally mailed maintainers of software projects that it is working perfectly for me. It's always a nice change of pace from bug reports.
I sometimes get emails and blog comments like this and always love them. One of my favorites was a comment last year, left on a 15 year old post about building my first gaming PC. I love how the comment said it was a "really fantastic build for the time". Something about "for the time" made me feel so retro :D
As a member of the younger generation, nobody really explained to me how powerful email contact actually is. Anyone who leaves an email somewhere for me to contact them gets a big kudos, anyone who also then replies to my email within 15 minutes is amazing and I always appreciate a direct line of communication.
I do wish IOS would support push mail for private mail servers.... You can't have everything I guess
Even lower risk is to email hn@ycombinator.com with duplicate posts or other issues on this site! It helps, and it gets you a bit over the fear of emailing. ;)
He has always replied to me, and has always been gracious, even when I felt a little too argumentative.
It’s hard being an hotheaded internet keyboard warrior like me when the moderators are going out of their way to remain polite and courteous when disagreeing.
This is why I share my email on my website and on my HN profile: it’s so much easier to see the human in 1:1 conversation.
I'm not sure if this is sarcasm, but I've been blown away by the thoughtful responses I've gotten from dang. They don't always come quickly, but I would expect that given how crazy I assume that inbox is.
I suspect the emails are triaged quickly and there is a low-priority bucket which may or may not ever get a reply. In my experience if there is a clear call to action and addressing the issue will have any sort of meaningful impact, it's unusual to not get a reply.
I don't often email the HN mods, but now and then I'll pitch an idea, and they respond. I usually end it with a big thank you to all of them, because they do thankless work, though I think most here on HN appreciate them for their work, this is an out of the norm community. :)
Also authors. Not the mega superstars of the world but even very bestselling novels as long as you show that you thought about it or actually did read the book
