Source for any of this? The notion of Canada accepting the plane on looser conditions than FAA is laughable.

You claim 1 is debunked but you’re replying to a quote from GP indicating Canada will accept the plane as per 1?

If you can back up the claim that 1 is debunked with a credible source, I suggest shorting Boeing stock because it means the 737 max is a complete failure, the line will likely be killed as it won’t be able to compete with the Neo, and stock price going to plummet through the floor.

Disrupting the control signal doesn’t force a landing. Even on super locked down DJI drones you can program several actions, including continuing a waypoint mission.

Jammers are a moronic idea for this task. They cause an unpredictable response and increase risk.

Refer to Fig. 11.1

If you need more help to identify REM or understand basic PV chemistry, get in touch with a local middle school chem tutor, they will help you out.

> Having read your link 2 and 3, I see they also don't support the point you are making (the first describes how to recycle turbine blades into concrete and is looking for more applications, the second says solar panels are 90% recyclable

The 90% recyclable figure refers to the materials that can be used in low grade applications. The remaining 10% are the rare earth minerals that actually make the panel work and need to be mined.

You’re not talking about recycling, you’re talking about downcycling to a nearly worthless product. It will be cheaper just to send the old panels to landfill. How are these power sources renewable if they are only possible if we keep mining our dwindling natural resources?

Hahaha that actually sounds plausible

Unethical doesn’t ring true for you even as fb faces a multi billion dollar lawsuit over targeted manipulation of individuals in concert with Cambridge Analytica?

You don’t see how a gpu accelerated numeric array would speed up ray tracing?

Understood.

I do suggest you seriously benchmark against clickhouse, because where single node performance is concerned, it is the tool to beat outside arcane proprietary stuff like kdb+ and brytlytdb. I have used single-node clickhouse and seen interactive query times where an >10 node spark cluster was recommended by supposed experts.

Clickhouse is not a mainstream tool (and I have discussed its limitations in other threads) but it is certainly rising in popularity, and in my view it comes pretty close to 1st place for general purpose perf short of Google scale datasets.

I upvoted the gp post just so it and your reply can be kept visible.

This dismissive attitude towards the slow but steady incremental erosion of privacy and authoritarian creep terrifies me. It's like people have completely forgotten about not-so-distant history, and are not just tolerating, but welcoming the mechanisms of oppression rolling out once again. In the name of catching a dozen or so criminals - just like every other time in the recorded history of oppressive regimes.

This has all happened before. For centuries. The same dismissive arguments have been used to defend the Gestapo and KGB. If there's a crime, why wouldn't you interrogate the family of everyone who was reported to be near the scene? Why wouldn't you force a confession and tick off the case if none of the leads are working out?

It takes only a few minutes of empirical thought to realize that not every crime must be solved, especially when that doctrine creates an incentive to 'solve' crimes with easy targets rather than the real perpetrator. You hit diminishing returns really hard really fast by investing extra resources into solving crimes with statistically negligible incidence rates. The only entity that stands to benefit is the proto authoritarian regime and its ability to target arbitrary population segments and continue expanding.

Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. Benjamin Franklin knew better.

The ingest time is due to updating the merge tree. You don't need a merge tree for etl... It's like the worst backing store you could possibly choose. You're also comparing an intentionally horizontally distributed query to a purely vertical one on a single node. You can see just slightly below the same query takes 0.2 seconds on a single node.

I was hoping to see some serious consideration given to these kinds of benchmarks, considering Clickhouse is one of the most cost effective tools I've used in the real world and occasionally outperforms things like mapd.

I was expecting your solution to outperform Clickhouse at least in some aspects, and a benchmark showing where it wins. Instead you reveal ignorance of Clickhouse and even the benchmarks you linked.

Your comment comes off as incredibly arrogant and at the same time incredibly misinformed. Disappointing to see this attitude from the team.
