That sounds nice in theory, but it seems obvious to me there is a major discrepancy between who is burdened with this responsibility, and who benefits from the result. Given many of these contributors are unpaid volunteers, maybe the infras

dav2d author here - the 5x number is just where we currently are, it's not the theoretical limit. We're hopeful that a significant amount of the increase we observe in dav2d relative to dav1d is in math code, which should be easie

It didn't become law (no 60 votes in senate), after Schumer sat on it for 6 (!) months. And there were earlier attempts to fix this, for example at the end of 2022 using budget/reconciliation - like what the Reps are doing here; b

If the issue is with general tax compliance of large multinationals, then congress should have done something about that. This tax rule has hit small software businesses particularly badly, so much so that it'll practically strengthen

LLCs pay 37%, not 21%. Plus state plus local. This can reach 50% in high-tax areas like CA or NY.

One of the reasons small businesses have been hit so hard with this is because for then (when incorporated as LLCs), their tax rate is 37% + state + local. I live in NYC and my LLC has a combined tax rate of 50%.

The opposite of what you're saying is "perfection is the enemy of progress", so let's move past them. I'm asking for more than "this is not the way". What is the way? How will we do this? This is critical,

> This isn't changing if it is taxed or not. This is untrue. The rule is not about taxation, but deductions/expenses. If your expenses cover most revenue, you owe little in taxes. With this rule, a particular type of expense (s

You're confusing corporate vs personal taxes. The salaries businesses pay are meant to be deductible business expenses. The business only pays taxes over the profit after these expenses are deducted from their revenue. The person recei

We don't talk about this enough. International R&D is not offshoring of call-centers to India. International R&D is the IP for the next generation of global communication standards being owned by US-based or foreign corporation

The way this is "fixed" right now, every five years we need another round of republican government to make things great again. If only enough democrats cared to fix this.

Large companies always find a way to not pay taxes. It's the little guys that end up paying (a lot!) more, to the extend that it cripples and kills them. But transformative innovation happens with the little guys. As a result, this tax

That part is not so weird, you didn't pay all salaries on January 1st. But amortizing salaries in general is ridiculous.

This is a weird take. Employees are supposed to be business expenses, that's the core idea of running a business: profit = revenue - expenses, where expenses are personnel / materials, and pay taxes over profit. Since the R&D

There's also section-174, which big corporations don't care about but kills smaller businesses left and right.

Binary size was a concern, so excessive inlining was undesirable. And don't forget that any asm-optimized variant always has a C fallback for generic platforms lacking a hand-optimized variant which is also used to verify the asm-optim

Sadly no mention of Section-174, which is a contributing factor. As a reminder, TCJA (2017) amended Section-174 (with a 5-year deferral) to require amortization over 5 (domestic) or 15 (foreign) years of all R&E expenses, and included a

It still surprises me every day that industry insiders discuss our current-era tech downturn and attribute it to a poor investment environment due to increased interest rates, yet nobody discusses the devastating impact of Section-174.

What if a court interprets fair use as a human-only right, just like it did for copyright?
