It is arbitrary, but we have to draw the line somewhere. It is not about money, tax is about money. This is about the extra work needed to accommodate for said obligations, it can involve several full time jobs, and the state considers that it is too much for a company of less than 50 employees. Really, it is a lot of paperwork, and the more a company spends on paperwork, the less there is to pay employees.

Could this be improved by a government agency where they do this paperwork for you at a per-employee cost if your company is under X employees (say 3x the limit at which the paperwork kicks in)?

The easiest improvement would be to remove the employer from the equation and just provide taxpayer-funded benefits to all. The main reasons employers are still involved are inertia followed by a concern that employees won't feel as obligated to stay in shit jobs.

Because it was CA focused, and I was remote. So most local providers were out of network. And it was not free ... Its been almost a decade, but I seem to recall that it was cheaper to add me to my (then) wife's coverage.

It’d be pretty annoying to have a Kaiser Permanente focused insurance plan and live in Ohio.

American health care is ridiculous, episode #193993.

Never be hired because you gave away most of your value for free?

Never be hired because trust is important in human endeavors

At least the illusion of trust. Much more valuable to market your past experience then privately give away your secrets in private.

IDK, I'm just show a concrete value. The person I replied to said it was "not hard". S I mentioned a minimum dollar amount that I've observed at many places seemed reasonable (it can be much much more, like if you cover 100% health for employees and family) Seems it wasn't helpful.

My point was just that this seems more like an issue for a business with low profit margins and low wage employees — not engineers, especially for a profitable company (i.e. not some early-stage startup relying mostly on equity). In this case, if they were making $20M/year with on the order of 50 employees it seems very short-sighted.

That's all true; I also think it's a wise choice to invest in your team for long term.

My point was to simply define a quantitative-value that folk who are not familiar with these costs could see as a minimum. Because "not hard" and $10k mean very different things. Hoping to help those HN readers who aren't familiar and/or are planning on starting a company.

There’s a reason guidelines ask you not to discuss downvotes, which always fluctuate. You were adding pure noise to the thread, and you tripled down on that.

This line in that post is mystifying: they peddled Infiniband, an inferior design based on bus technology, but repositioned as a point to point network

At least initially (~2005 or so?) we had customers who were given free IB for their HPC clusters ripping the IB out and replacing it with with paid Myrinet installations because they could never get their IB clusters to work reliably. Although we had the superior product, we could not market our way out of a wet paper bag. Our CEO counted on our (then) superior engineering & expected our products to market themselves…

Where'd the name Myricom/Myrinet come from? "Infiniband" is a pretty cool name.

Probably shouldn't reveal this but, Google are using it internally for their accelerated networking in their cloud, pretty much all Lanai hardware is deployed in GCP infrastructure.

What explains why Amazon has been relatively open about Nitro but Google has never said anything about how their NICs and SSDs work? It can't be because it's secret sauce; Amazon beats them on latency etc.

We've been fairly open about how Google Cloud Networking works -- https://www.usenix.org/conference/nsdi18/presentation/dalton

There's also some more recent coverage on IPUs that I don't have a handy link to.

How would Lanai compare to a simple RV32I isa/core for this application area? The short description in OP doesn't really clarify what, if anything, might be specifically compelling about this arch.

Lanai is significantly older than RISC-V. These days you'd likely easily pick designing or using an existing RISC-V core for an application like this, possibly adapting it to your particular usecase. The decision is different, however, if you happen to have the entirety of the Lanai engineering team on board and own the entire Lanai IP portfolio. :)

Reminds me of the various uses that have come of the IP of the https://en.wikipedia.org/wiki/ARC_(processor) — including inside the Intel Management Engine! — since its ignominious start as the SNES SuperFX chip :)

I don’t know if it’s illegal, but basically every health care plan will deny you if they know you have other coverage. This is bad advice.

You’re wrong. It is perfectly common to have double coverage. I had it on multiple occasion. You can read about it if you google “coordination of benefits”.

You’re right. I don’t know if this varies by state, but for sure I’ve had to sign contacts stating I didn’t have any other insurance in order to start various plans. So I don’t think this is universally ok but clearly there are situations that allow it, seemingly most common in conjunction with Medicare.
