I tried my standard testprompt:

    Two cars have a 100 mile race. Car A drives 10
    miles per hour. Car B drives 5 miles per hour,
    but gets a 10 hour headstart. Who wins?
And the Liquid-40B model failed with a long explanation why car B wins the race.

Amusingly, the explanation is quite convincing and very similar to how Zeno explains in one of his paradoxes that a fast runner can never overtake a slower runner with a headstart. Because every time the fast runner gets to the point where he saw the slow runner, the slow runner is already a bit further along the track.

I got this >>

To determine the winner, we need to calculate the time it takes for each car to complete the 100-mile race.

For Car A: Speed = 10 miles per hour Distance = 100 miles Time = Distance / Speed = 100 miles / 10 miles per hour = 10 hours

For Car B: Speed = 5 miles per hour Distance = 100 miles Time = Distance / Speed = 100 miles / 5 miles per hour = 20 hours

However, Car B has a 10-hour headstart, so we need to subtract that from its total time: Adjusted Time for Car B = 20 hours - 10 hours = 10 hours

Both cars take 10 hours to complete the race, so they tie.

Author here. Did not expect to see this on HN at all. Just an engineering war story I shared.

Was there ever any consideration given to building a "testing harness" to physically simulate the F35 landing? Something like the "dead load" testing that the EMALS undergoes. Just in reverse. Anyway, that was great read.

The 11,000 may be limited by the suspension system.

So in terms of comparisons I don't think you're wrong, but it might be better to compare it to the F-150 Lightning for more of an apples to apples comparison. The F-150 Lightning Platinum vs Cybetruck AWD is probably the most fair comparison in terms of specs, but the CT is ~$20,000 cheaper

If we compare the F-150 Lightning Lariat with XR Battery to the Cybertruck AWD, because of price:

F-150:

Range: 320mi

Towing: 7,700lbs

Curb Weight: 6,361lbs

---

CT:

Range: 340mi

Towing: 11,000lbs

Curb Weight: 6,603lbs

---

F-150 Lighting Platinum to CT Cyberbeast, because of price:

F-150:

Range: 300mi

Towing: 8,500lbs

Curb Weight: 6,893lbs

---

CT:

Range: 320mi

Towing: 11,000lbs

Curb Weight: 6,843lbs

A different comparison would be the following (from the manufacturers sites)

----

  Ford Lightning Pro: $50K
    240 Mile EPA-Est. Range – Standard-Range Battery and RWD171
    0-60 MPH in 4.1 seconds - Standard Range Battery\*
    Wireless Integration with Apple CarPlay® and Android Auto™
    12-inch Touchscreen
    Mega Power Frunk

  CT Rear-Wheel Drive: $61k
    Available in 2025
    250 MI. Range (EST.)
    6.5 sec. 0-60 mph
very similar ranges and specs, but and CT is 10k more. Also, ships in 2 years.

Mearsheimer was prescient when he advocated Ukraine be allowed to keep a strategic nuclear stockpile in the early 90s when the US admin was pushing to disarm Ukraine, post breakup of USSR.

  The Case for a Ukrainian Nuclear Deterrent

 Most Western observers want Ukraine to rid itself of nuclear weapons as quickly as possible. In this view, articulated recently by President Bill Clinton, Europe would be more stable if Russia were to become "the only nuclear-armed successor state to the Soviet Union." The United States and its European allies have been pressing Ukraine to transfer all of the nuclear weapons on its territory to the Russians, who naturally think this is an excellent idea.


  President Clinton is wrong. The conventional wisdom about Ukraine's nuclear weapons is wrong. In fact, as soon as it declared independence, Ukraine should have been quietly encouraged to fashion its own nuclear deterrent. Even now, pressing Ukraine to become a nonnuclear state is a mistake.


  A nuclear Ukraine makes sense for two reasons. First, it is imperative to maintain peace between Russia and Ukraine. That means ensuring that the Russians, who have a history of bad relations with Ukraine, do not move to reconquer it. Ukraine cannot defend itself against a nuclear-armed Russia with conventional weapons, and no state, including the United States, is going to extend to it a meaningful security guarantee. Ukrainian nuclear weapons are the only reliable deterrent to Russian aggression. If the U.S. aim is to enhance stability in Europe, the case against a nuclear-armed Ukraine is unpersuasive.

But, he does give Putin a pass on the invasion itself. Couldn't Putin have won the desired concessions with just sabre-rattling and having a skirmish on the border instead of a full on invasion, which is slowly destroying both Ukraine and Russia.

Remote is ok if your personality doesn't mesh with an office. And you are the CEO. This should do wonders for feeling of "ohana" at salesforce.

10 micron tolerance on body panels sounds like a typo. Coefficient of thermal expansion of steel is 6.5 microns/in/F. So, a 2 degrees F change in temperature will put parts over an inch out of spec. Imagine a 3 foot (36in) body panel going from a 80 degree stamping area to 75 degree assembly area. It will be out of spec by over 1000 microns!

We perform a cost and runtime evaluation of Graviton instances for Apache Spark on EMR AWS using the TPC-DS 1TB benchmark.
wazokazi · 2 years ago
The total cost($) vs total runtime(s) graph doesn’t look correct. Longer runtimes should cost more, so the dots should cluster in the top right quadrant.
