tiffanyh··on Visa, Mastercard, Major Banks Facing New Litigation over 'Anticompetitive' Fees
Let's use Stripe as an example, there fee is 2.9% + 30 cents.

That 30 cents - is what's often ignored but makes up a disproportionate amount of the fee.

On a $30 transaction, paying 30 cents is equivalent to a 1% fee.

So Stripe on a $30 transaction is effectively 3.9% in fees (on a $30 transaction).

Interchange (which goes to the issuer), would only be approx 1.75% (of the 3.9% fee charged by Stripe).

What seems to be getting lost is that the acquirer, not the payment network, sets the Merchant Discount Rate. The acquirer is also the merchant’s direct payments provider.

Yet the acquirers seem to be always absent from these lawsuits.

Can you explain more as to why T&C don’t allow for this.
tiffanyh··on Ask HN: What do you think about Fractional CFOs
“Fractional” seems to be the modern-day buzzword for a 1099 contractor.

(and your experience will all depend upon the contractor)

tiffanyh··on OpenSSH 10.6
> I raised an issue on the tracker

I thought OpenBSD / OpenSSH operate without a tracker and it’s all email distro based.

tiffanyh··on Gleam doesn't compile to Erlang source anymore
The title is a bit misleading because one might imply that Gleam no longer compiles to something Erlang can use (not true).

From the article:

> Over the last few months Giacomo Cavalieri has entirely rewritten Gleam's Erlang code generator that has an entirely different design, and most notably, outputs a different format. Previously Gleam generated Erlang source code, now it generates Erlang abstract forms.

tiffanyh··on JetBrains reported a net financial loss first time in its tracked history
I thought JetBrains is a private/bootstrapped company.

Where are these financials coming from?

tiffanyh··on Powerless F1 drivers frustrated by Bahrain F1 software glitch
F1 are effectively prototype cars.

Every GP is a slightly different car running bleeding edge tech and code.

tiffanyh··on What Meta got right with Muse
It isn’t though.

Muse is:

- a single thread

- has avatars that you can name

- has approval cards

Now dots is similar in concept but that only launched a few days ago and Muse launched a month ago.

tiffanyh··on What Meta got right with Muse
UI/UX

Many times, UI/UX makes all the difference in user adoption & use.

tiffanyh··on Every SaaS business will become a harness around a model
> I’m using the term “harness” broadly to mean all the infra, interfaces, context, and state that surround a stateless LLM

When the definition is that broad, aren’t you effectively already defining what SaaS is today.

Especially when you include interfaces in that definition.

tiffanyh··on Burning Man death rates – A short lesson in statistics
Isn’t there selection bias though …

because if someone feels physically well enough to go to Burning Man, then the probability of them dying in the next week is near zero in comparison to the national average (which includes individuals hospitalized, terminally ill, etc).

tiffanyh··on Backblaze drive stats for Q2 2026
Could this be a situation of extremes … where the drive either (a) fails early in its life … or (b) lives a very long life.
tiffanyh··on NASA asked several former SR-71A staffers to help secret restart
Didn’t satellites with superior optics and realtime video streaming … kill the need for an SR71 update?
tiffanyh··on Dots: Always-on agents
The video demo confuses me.

It’s having agents update websites, charts, etc for human consumption.

But isn’t the future the AI labs are (subtly) saying is that no human digital interfaces need to exist … and the interface is just the agent surface itself.

tiffanyh··on As A.I. makes law firms more efficient, clients ask: 'Where's my discount?'
Do you have any issues with thr tech industry selling software licenses?

Because a lawyer selling a contract template, is in many ways, very similar in concept to tech industry selling a software license/seat.

They are both akin to “templates”, and selling IP.

tiffanyh··on Oracle cites 'force majeure' to shield itself on controversial data center
It's not that simple though.

It's not like you get the permit before you have even bought the land and designed the plans/architecture/engineering for the data center.

You have to do all of that first, and only once all of that is done, can you submit for a permit.

Which can take not just months, but maybe even a year (or more).

So the situation is, regulation changed during the planning phase. So what do you do now? You obviously can't deliver on a contract that would cause you to break new laws/regulations - that didn't exist when you started all of this.

tiffanyh··on Oracle cites 'force majeure' to shield itself on controversial data center
Maybe some are not as familiar with this, but I'll use Texas as an example.

In 2025, Texas state government announces a $40B infrastructure investment specifically calling out building data centers for AI as a key part of that package.

https://gov.texas.gov/news/post/governor-abbott-google-annou...

Then, just this week, Texas government reverse their position and halts permits for all data centers:

https://gov.texas.gov/news/post/governor-abbott-directs-tceq...

I'm not trying to defend Oracle, but I can understand their perspective on this.

If the state government is only now blocking what their contract commits them to deliver, it's unreasonable.

tiffanyh··on Oracle cites 'force majeure' to shield itself on controversial data center
In your example, governments we not enacting new regulation that banned you from getting a new job.

In this situation, governments are now enacting new regulation that ban companies like Oracle from building new data centers.

tiffanyh··on Oracle cites 'force majeure' to shield itself on controversial data center
I realize there’s a lot of hate in this thread, but I think there’s another side to this.

Force majeure is basically there for situations where something outside a company’s control prevents them from delivering on a contract.

I can see Oracle’s argument here. A number of states and local governments that were originally very supportive of new data centers, including places like Texas and Pennsylvania, have since started blocking or restricting new construction.

If Oracle signed these contracts and the government later changed the rules and have stopped those projects from moving forward, it’s hard to argue they should still be held to the same delivery commitments.

(That seems pretty close to the type of situation force majeure is meant for.)

tiffanyh··on We just shipped support for the ugliest part of HTTP: Vary
I just wish CF would enable Enterprise functionality to lower (paid) tiers as they promised a year ago yet haven’t delivered on.

tiffanyh··on How did AMD Ryzen get 50% faster in two years?
The AMD Ryzen 9 9950X3D / EPYC 4585PX is a beast for 99% of compute workloads.

It has the highest base clock of any modern AMD chip (4.3 GHz), plus 16-cores, which is already more than most workloads need.

Can’t wait to see what Zen 6 brings early next year. Rumors say 24-cores and another big jump in single-core performance.

tiffanyh··on What Sun got wrong
On-prem vs cloud though, is two very different things.

In the later, I don't have to worry about hardware/power/networking/etc at all.

tiffanyh··on What Sun got wrong
I wonder if bcantrill will ever get back into cloud hosting ... to revive his Joyent days (which he alludes to without naming directly in the post).

tiffanyh··on Performance Improvements in .NET 11
This post was so refreshing to read, because it reminds me of a time of solid engineering & writing in a pre-AI era.

I’m afraid posts like this might become fleeting.

Great explanation.

Do you think this could be extrapolated to areas with no objectively verifiable results / outcomes?
