theolivenbaum··on Once Claude can measure something, it can make it faster
You're missing the point where: in complex systems, sometimes optimizing code is both a high effort undertaking, and can totally not pay off. Having done hundreds of such exercises on our software over the years, it's liberating to have an idea of how to make something faster, being able to validate it without the fear of having to throw it all in the trash if it fails after days of work. What is still important is being able to provide proper guidance - we even built new tools to allow an AI agent to analyze memory usage in more depth, and instructions on how to benchmark in cloud environments where shared CPU usage and VM reallocation happen all the time and confuses the AI all the time with measurements
theolivenbaum··on What's in a PowerPoint File?
They added a whole set of skills and python scripts for interacting with office files using libreoffice headless, it's not writing the XML files directly
theolivenbaum··on Google copybara: moving code between repositories
Wild times when one can go from a HN post about an interesting open source code to a port to a new language in a matter of hours (wip, but almost complete: https://github.com/theolivenbaum/copybara)
theolivenbaum··on Microsoft admits Windows 11's dedicated Copilot key breaks certain workflows
For me it was even worse than that. One laptop has copilot blocked by policy, and it shows a blocking modal every time you press the key by mistake
theolivenbaum··on Show HN: Red Squares – GitHub outages as contributions
If I remember correctly the status page was not precise before the acquisition - so take with a big grain of salt the 100% pre-acquisition values
theolivenbaum··on Microsoft is employing dark patterns to goad users into paying for storage?
It's worse than that - the feature exists in the paid OneDrive app, it lets you scan, edit, add pages etc just like the office lens. It just doesn't save the output - scanned files just disappear in the void.
theolivenbaum··on 15 years later, Microsoft morged my diagram
Seems like this is going to be the year of AI slop being released everywhere by Microsoft. Just wish they'd put as much effort into a post morten for this one as they're doing for a diagram on a blog post https://github.com/microsoft/onnxruntime/issues/27263#issuec...
theolivenbaum··on We need more water than rain can provide: refilling rivers with desalination
Maybe I'm not seeing it but wouldn't it be just easier to pump the river water back up instead of letting it flow on the sea?
theolivenbaum··on “ZLinq”, a Zero-Allocation LINQ Library for .NET

theolivenbaum··on “ZLinq”, a Zero-Allocation LINQ Library for .NET
There are some minor breaking changes like the order of iteration is not always the same as the official Linq implementation, or Sum might give different values due to checked vs unchecked summing. Probably not an issue for most people, but a subtle breaking change nevertheless.
theolivenbaum··on “ZLinq”, a Zero-Allocation LINQ Library for .NET
To add on that, you can define your lambdas as static to make sure you're not capturing anything by mistake.

Something like dates.Where(static x => x.Date > DateTime.Now)

theolivenbaum··on Ropey – A UTF8 text rope for manipulating and editing large text
There's also a really nice implementation of Rope for C# here: https://github.com/FlatlinerDOA/Rope
theolivenbaum··on Building LLMs is probably not going be a brilliant business
Specially because there are no network effects and no lock in.
theolivenbaum··on Air traffic failure caused by two locations 3600nm apart sharing 3-letter code
Netflix did that many years ago, interesting idea even if a bit disruptive in the beginning https://netflix.github.io/chaosmonkey/
theolivenbaum··on Defending Open Source: Protecting the Future of WordPress
What a bunch of corporate newspeak. Their demand of 8% of gross revenue in annual license fees, or >$30M for 2024, shows how much this was only about profits and not about contributing to the WP community:

"It’s important to note that a significant part of Automattic’s revenue, including any licensing revenue, is channeled back into supporting the WordPress community, as Automattic is currently contributing 3,552 hours per week to the WordPress project. This comes out to something in the order of $20M annually in salaries."

And the post then goes from defending open source to how their actions made everyone's websites safer (which, they didn't) and how you should migrate your website to their hosting solution. Despicable.

theolivenbaum··on Four dead in fire as Tesla doors fail to open after crash
I think the original quote was "One in a million is next Tuesday": https://learn.microsoft.com/en-us/archive/blogs/larryosterma...
theolivenbaum··on DOJ sues realpage for algorithmic pricing scheme that harms renters
Isn't that precisely what they were doing? Forcing landlords to follow the recommended prices?

"RealPage thus makes it hard for customers to override its recommendations, according to the lawsuits, allegedly even requiring a written justification and explicit approval from RealPage staff." From: https://www.theatlantic.com/ideas/archive/2024/08/ai-price-a...

theolivenbaum··on Dropbox Acquires Reclaim.ai
Reminded me of their Command-E acquisition from a few years ago (https://blog.dropbox.com/topics/company/welcome-command-e-to...)
theolivenbaum··on Xapian: Open source search engine library
That's what our app does: curiosity.ai, local index, support for many files types and apps out of the box, and integrated local OCR, STT and even local LLM
theolivenbaum··on Comma.ai: Refactoring for Growth
You forgot to mention how he also single-handed solved search at Twitter /s
theolivenbaum··on X ( Twitter) is using Bun in production
And nowadays by ego
theolivenbaum··on Everybody gets a star: Yelp's effect on restaurants and reviews
They turned into an online version of the mob. Pay them and they'll take care that your bad reviews are gone. Don't pay and risk getting a few extra bad reviews
theolivenbaum··on Ask HN: Have AI learn my own business Knowledge(verity of formats) for chat bot
If you want to try our software (includes search, RAG, file handling, and a bunch of integrations, and can be deployed on prem or cloud), happy to give you a license in exchange for some feedback! Just shout me an email at rafael (at) curiosity.ai
theolivenbaum··on Google Maps is ruining us
Going up the wrong road and ending up inside a favela https://www.france24.com/en/20170807-british-tourist-shot-af...
theolivenbaum··on Crowdstrike – Statement on Falcon Content Update for Windows Hosts
Came here to say that. The nerve one has to have to put a sign up for a trial on that page - guess any publicity is better than no publicity after all
theolivenbaum··on Google's Gemini AI caught scanning Google Drive PDF files without permission
Except that there's still a grey area on who owns the copyright of the generated text, and they might be able to use the output without you knowing.
theolivenbaum··on Ask HN: What's the weirdest bug you ever had?
Reminds me of the MIT's magic switch story http://www.catb.org/jargon/html/magic-story.html
theolivenbaum··on Mathematical Optimization for Cargo Ships
This is so true! Worked in the past on flight optimization problems and the most obvious solution (fly in a direct trajectory, or almost direct but considering wind) would easily achieve a 10% reduction in fuel usage. Now implementing that would be a nightmare, with so many layers involved and the need for realtime comms between aircraft and ground to keep the solutions in sync and conflict free. Unfortunately reality is always more complicated

theolivenbaum··on Windows AI feature that screenshots everything labeled a security 'disaster'
While I'm not a fan of the almost forced OOBE setup, I really don't understand the complaining regarding security. It's again another case of if you can run code on my computer you already own it. As Raymond Chen put: "you’re already on the other side of the airtight hatchway. And you’re bragging that you can do something annoying like a denial service, apparently unaware that being on the other side of the airtight hatchway gives you the ability to do far more interesting (and threatening) things".

This kind of "vulnerability" has been a constant topic of his blog in the past:
