Re:Gemini 3.8 Flash on Wednesday September 02, 2026 @03:20PM (#49541081)
IME 3.1 Pro still has better system-instruction following than Flash 3.7, esp. when there're many conditions and clauses. 3.1 also writes better prose for technical material than Flash 3.7.

Once the system prompt complexity goes up, Flash starts to write very dense english. it might be fine for tasks like coding, but not for user-facing text meant to be digested by the average person.

I haven't tested 3.8 on my workload yet.

plug: studymode.ca/ml is an AI-generated cirricculum + chapters/lessons that teaches ML by building practical projects

the lessons have svg diagrams, ai chat inline (google docs), etc

apologies if this comes off as slop, but its been working great for me.

Re:Gemini 3.7 Flash on Thursday August 13, 2026 @10:15PM (#49294060)
I'm finding Gemini 3.7 speaks a lot more academically. Its explanations are not clear and intuitive by default.

Maybe this has to do with all the RLVR it went through, where reasoning through difficult academic/coding problems caused it to think and speak a certain way.

The benchmarks looks great but it doesn't feel as legible, so maybe it's more meant to be an agentic model rather than an everyday model whose outputs are read by humans?

does anyone know how well this 5x petaflop improvement translates to real world performance?

I know that memory bandwidth tends to be a big limiting factor, but I'm trying to understand how this factors into it its overall perf, compared to blackwell.

Some fine tuning data questions:

i see the the dataset Google published in this notebook https://github.com/google-gemini/gemma-cookbook/blob/main/Fu... -- from looking at the dataset on huggingface, it looks synthetically generated.

1. do you recommend any particular mix or focus in the dataset for finetuning this model, without losing too much generality?

2. do you have any recommendations for how many examples per-tool?

thank you for your (and your teams) work!

Re:Meta hiding $27B in debt using advanced geometry on Friday November 28, 2025 @11:28AM (#46080064)
I asked ChatGPT to make this more readable since it's a mix of satire and actual information:

==============

Meta wants to build a huge AI data center campus in Louisiana. It costs about $28–29 billion. Instead of just borrowing the money itself and putting the debt on its own balance sheet, Meta uses a maze of LLCs and contracts to:

- Get $27.3 billion of debt raised by a special company called Beignet Investor LLC (80% owner of the project).

- Keep that debt off Meta’s official balance sheet, even though:

▫ Meta designs the campus,

▫ pays for overruns,

▫ pays the rent,

▫ guarantees the value at the end,

▫ and will basically be the only user.

In real life, this is basically Meta borrowing to build its own data center. On paper, it’s “someone else’s” debt.

Why is this off-balance-sheet?

The accounting rules say you only have to put an entity on your balance sheet if you “control” it and take on most of the risk/benefit.

Meta’s position is: “We don’t control this JV company, even though we do all the important things and take on all the risk.”

The rating agency in the piece is mocking this. They list all the ways Meta obviously controls and supports the project, then say: under current accounting rules, if Meta insists it doesn’t control it, we all politely pretend that’s true. So the $27B debt doesn’t show up on Meta’s balance sheet, even though economically it’s Meta’s problem.

Ah, makes sense :)
Re:Database Fundamentals on Friday December 15, 2023 @11:44AM (#38655870)
There is a bug in the compaction method:

  def compact(sstables, output_sstable):
    # Ordered by ascending key. pop() results in the item of  the smallest key.
    heap = heapq.heapify([(sstable.next(), sstable) for sstable in sstables])

    while (item, sstable) := heap.pop()
        if not item.is_tombstone():
            output_sstable.write(item)
You should only skip tombstones when you are compacting the final (i.e., largest) level, instead of between every level, an entry for in a lower level will unmask itself because the tombstone in the upper level was compacted away.

It's one of the properties of LSM-based DBs that deletions/tombstones records linger for a long time, though some databases (eg RocksDB) put in some optimizations to get around this.

Co-incidentally, I fixed this issue yesterday in my own implementation of lsm db (in rust): https://github.com/vardhan/lsmdb/commit/f3fd32302682a447cc02...

Re:Go 1.17 Beta on Friday June 11, 2021 @11:31AM (#27474687)
Apologies for my tone, I didn't mean to insinuate you weren't experienced. I guess I was wondering what was wrong with copy(), thanks for the link!

IMO, copy() is well-designed and the semantics are sensible. I think the other examples in that article are not clear, and the semantics have me second guessing what they're doing.

> Drawback 1: if s is nil, the result sClone is not nil.

I can see how this particular semantic seems an issue, but I think its sensible. If your copy() returned nil and you wanted to use it, then you'd have to check if sClone is not nil first, so that if statement is unavoidable. Instead, it's often safer in practice to check ahead of time.

Sorry again for my tone, it's easy to appear rude on the internet on a late night.

Re:Go 1.17 Beta on Friday June 11, 2021 @01:44AM (#27469744)
It's surpring that Go 1.17 discountined support for MacOS 10.12 (or older), which released only 4 years ago.

Along with deprecating Intel support, it seems like Apple, their users and the ecosystem is totally fine not giving a shit about supporting aging software. It doesn't seem like anyone cares that much either.

Even more impressive that on average, Macbooks have a much longer lifespan than other laptops, while the software they run is intolerant of old versions.

Re:Go 1.17 Beta on Thursday June 10, 2021 @07:17PM (#27467284)
My favorite part:

Go 1.17 implements a new way of passing function arguments and results using registers instead of the stack. This work is enabled for Linux, MacOS, and Windows on the 64-bit x86 architecture... For a representative set of Go packages and programs, benchmarking has shown performance improvements of about 5%, and a typical reduction in binary size of about 2%.

Re:Astro: Ship Less JavaScript on Tuesday June 08, 2021 @05:07PM (#27440807)
Thanks for all the hard work and open sourcing it!

Are there benchmarks/numbers for how Astro improves page load / page download size for a relatively complicated web app? I wasn't able to find it on the website or the README.

Design docs are a heavy-weight way to accomplish 3 major things, roughly in the order of importance:

1) Get feedback from your peers and other teams who need to interface with your design. Your design, or the problem you think you are tackling, could change based on their feedback.

2) Future readers can get a lot of context. Specifically, the design doc documents the trade-offs you considered and chose; this helps future engineers fully understand the problem space before second-guessing major decisions.

3) Leave some trace that you initiated/drove an effort of some design, for career/promotion purposes. You can demonstate how many stake holders/teams your work had to touch, and how difficult the problem & solution are based on various metrics in the design doc (# of ppl that participated in the review, # of services/components your design had to touch, etc). Personally this is my least favourite reason to write a design doc, mostly because I find people write heavy-weight design docs when it serves no other purpose than for perf, and design docs are often.. embelished when they dont need to be.

Instead of a design doc, you can just file a bug, or shoot an email to a wider team, to accomplish the 3 things above. However, it becomes increasing inefficient to solely rely on bugs/email as the # of peers/stake holders increases, the scope/complexity of your project increase, or the communication overhead in your company increases.

I think it really depends on how mature, how complex, how isolated, and how big your project/working group is.

Where does your work fall, and what kind of process do you personally use to accomplish 1,2 & 3?

Re:The biggest threat to Rust's sustainability on Friday March 19, 2021 @05:03AM (#26511303)
I don't think the release cadenece (6 weeks) is the cause for how fast the language was changing.

As a counter examples, Go release roughly every ~26 weeks and mostly has releases with minor updates. Chromium releases every 6 weeks but not every release has major updates; they are mostly bug fixes and minor improvements. Even Android is decoupling its system services into components which can be updated through the Play store at a much faster cadence than their yearly releases.

I agree that Rust needs to now focus on polish over new features at this point, but I'm not sure that Rust should've done something differently, especially around its release cadence. I don't think it would've been a good contender for serious companies if they hadn't invested heavily in async, for example.

VS Code's Remote Development. I'm not sure how many folks rely on this, but its been amazing for me.
Re:Square acquires majority of Tidal in $297M deal on Thursday March 04, 2021 @01:36PM (#26346285)
TIDAL isn't getting traction & Jay-Z wants to sell it <=> Square needs a hook into the rap industry because they market really well there. Square has been paying rappers to promote Cashapp since 2018.

Here's an article written 1 year ago about the Cashapp's traction with the hip hop community: https://trapital.co/2020/03/18/how-hip-hop-helped-cash-app-g...

An excerpt:

Here’s Square CEO Jack Dorsey at a 2019 investor conference via Wall Street Journal:

“This is also something we weren’t expecting, but I think Cash App has touched in the culture. We’ve just benefited from people loving it and wanting to sing about it, and putting it in their music videos, and it’s amazing how much that spreads.”

Well, here goes another thread about free speech vs. ethical discourse, where atleast one side uncompromisingly refuses to put themselves in the shoes of the other.

Just to fast-forward this thread a bit for everyone:

- Free speech doesn't exist on some for-profit company's platform. Communities should be moderated on some ethical standard for the benefit of peace

- Free speech trumps ethics and peace -- without free speech, we have neither
