For a Qwen 3.6 35B / 3B MoE, 4-bit quant:

- parsing a 4k prompt on a M4 Macbook Air takes 17 seconds before generating a single token.

- on an M4 Max Mac Studio it's faster at 2.3 seconds

- on an RTX 5090, it's 142ms.

RTX 5090 uses more power than an M4 Max Mac Studio but it's not 16x more power.

personally, i was on a flight in May from SFO to EWR and my flight flew 2h30m towards Newark, then back to SFO when EWR stopped accepting landings: https://www.msn.com/en-us/travel/news/united-flight-that-was...

granted this was an especially egregious situation and not the norm, but it feels like these types of issues are on the rise based on my anecdotal experience. there were a number of full ground stops at newark due to ATC in the weeks after this. it was national news.

Maybe in aggregate flights have fewer delays but every single flight I’ve taken this year has been delayed (on top of the padded flight times the article mentions). I’ve flown about half a dozen trips.

I also hate the argument that the free market should solve the pricing problem. Airlines have exclusivity on airport gates. Any frequent flier on the SFO -> EWR route knows that if you want to save money you can book an Alaska flight instead of United but Alaska has significantly fewer gates and usually gets delayed when arriving waiting for one. Flights aren’t exactly equal commodities and even if the airlines were well-run, contracts for these gates are locked in.

Pricing stats here also fail to account for business class vs economy pricing. Business class prices on tickets have skyrocketed, way outstripping purported CPI. In some cases prices have doubled or more since COVID.

1) united healthcare made 90 billion dollars gross profit in the last 12mo, and that's only one health insurance company. claiming that it's not a great business at a 2-3% profit margin ignores the scale of money involved, and ignores that the customer for health insurance is truly captive.

2) you're right that america has very high prices in healthcare. doesn't it seem bad that private insurance companies are incentivized to make things cost as much as possible so they can skim that 2-3% off the top? insurance companies negotiate and set prices for services and pharmaceuticals. they now own the pharmacy benefit management companies that would normally be incentivized to negotiate for lower prices.

i would expect in a public health care system that rejects procedures, they would follow consistent guidelines and rules. american health insurance companies will arbitrarily reject a percentage of procedures that they know they should be accepting in order to keep their profit margin in the right range.

i think it's hard for me to see the argument that health insurance companies are a net-positive or even net-neutral party in the united states. i don't think it's a coincidence that we have some of the highest prices and some of the worst outcomes.

if apple was saying you had to support their payment processor alongside others (so you could opt into paying +27% and getting easy cancellations), that would be one thing, but they don't allow you to have any other options available in the app, which i think is where the anticompetitive complaints start to feel more valid.

1. vmotion + storage vmotion - you can live migrate a vm from one hypervisor host machine to another. you can also live migrate the underlying storage (good if you want to consolidate storage servers, rebalance disk load, etc). with some caveats, you can do all of this without any downtime in the vm. it's not just a simple suspend on one host, resume on another host. a memory snapshot is migrated while the vm is still running on the first host, and when the amount of dirty pages starts to converge, they flip the vm over to the new host. similar idea for storage vmotion.

2. fault tolerance - for single cpu vms, you can use vmware's record-replay technology to execute a secondary vm in a "shadow" mode which replicates all of the nondeterministic events across the network. if one hypervisor host dies, the other can take over with no downtime. this is great when you need to add HA for a legacy application.

3. vsan - generally you run these systems with some sort of shared storage (nfs or iscsi attached SAN, or something like that). a SAN can be really expensive and a single point of failure. vmware can create a "virtual san" from a cluster of your esxi hypervisor hosts. as you can imagine, it has all sorts of HA features and can rebalance workloads to improve performance.

there are more, but that's just a few interesting features.

Unclear to me if this is really the meaningful reason that Paul's company succeeded (I'd say obsession with programming languages can be a counter-indicator for productivity), but it clearly resonated with a lot of people since that essay is arguably the onramp into Paul's fame. A lot of programmers read that essay back in 2001. His popularity as an investor who understood engineers arguably catapulted YCombinator
