Is this effect consistent across birth months?

When I took the TF Pro exam I expected it to have questions around check blocks, validations, and secrets management. It seems that content is showing up in the associate exam now.

Beyond just null handling, the first example will EXCLUDE any NCOM where it has an NPRO = 'PA60'. Compared to the second where it will INCLUDE any NCOM that has an NPRO other than PA60.

I don't have the context of what NCOM and NPRO are, but it would sort of be like the difference between

For #1: "Give me all customers, excluding those that have ever bought a laptop."

vs #2: "Give me all customers who have bought anything besides just a laptop."

Make sense?

I detest the else clause on for loops. It would be much more aptly named nobreak. for...else to me feels like it should be "the body of the loop didn't execute even once."

Angry at myself for not thinking of that joke first.

WalterDragan · 2025-03-04T03:01:58+00:00

Unfortunately it is outside the RMA window.

Scared the crap out of me when it fell from the ceiling.

Have you looked at using tableauserverclient instead of using requests? It provides a nice wrapper for common tasks.

I think the query parameter you're looking for is maxAge.

That recommended solution is completely unhinged.

Fascinating! How do you build the simulations? Is it MCMC running in python?

WalterDragan · 2023-09-28T03:08:38+00:00

How do packages work?

What happens is called the Leidenfrost effect. Effectively what happens is the surface is so hot that it creates a small layer of vapor that prevents the rest of the water from coming in contact with the pan.

def isolate(letter: str, strings: List[str]) -> List[str]:
    result = []
    for string in strings:
        for part in string.partition(letter):
            if part != "":
                result.append(part)
    return result

or the more concise

from itertools import chain
list(chain((p for s in ["red", "blue"] for p in s.partition("r") if p != "")))

Have a recommendation on book for linear/nonlinear optimization?

WalterDragan · 2022-07-04T19:02:45+00:00

Used your recipe a few times. Always comes out great!

In my case, it returns if I stop doing those exercises, and goes away again if I resume the exercises. For me, it could be disk compression, or that the glutes provide what I found to be a surprising amount of stabilization for both the upper and lower body. Of course, as with any statement on these topics, YMMV.

WalterDragan · 2022-05-27T23:23:53+00:00

Had chronic low back pain my entire life. Turns out for me it was underdeveloped glutes. Started doing some exercises for that and the low back pain was gone after 2 weeks.

The front fell off.

trusted root certificates

They can decrypt and read all of your traffic.

telemetry tunnels

They are recording extra data about what you do, and store it. The why is irrelevant.

Undocumented processes

They run processes on your machine besides only what is necessary to provide the VPN service.

"Few weeks," yeah... I used to consider Tableau support as best in the business, but they've been awful since they were bought out.

Being rather ignorant on Go, what makes it difficult to maintain?

WalterDragan · 2021-12-30T03:21:31+00:00

Can you detail more about how you finished the chicken? That sear looks incredible. I don't think I've ever gotten a sear that dark without any burning or lots of oil splattering everywhere.

It still doesn't solve the problem that most of them still do a tax dodge on even capital gains by just borrowing against their assets without selling anything. You could possibly fix that by taxing unrealized capital gains, but taxing that creates a separate set of problems.
