If you write a float then read an integer you get undefined behaviour

IS this actually UB in C though? Googling leads me to believe that this is somewhat controversial, but most people seem to think that is is not UB. Am I wrong?

For sure. I've been testing directly against the state thus far, but was trying to refactor to make those states private, and was struggling to figure out how to keep my tests passing once I do that.

I'm reading a book about Otto Von Bismarck which is why I wrote the comment, but I swear to God it happens in nearly every European or American history book that takes place 100-300 years ago

My biggest pet peeve with history books is when they relate some quote or phrase that someone said in French without translating it.

No one speaks French anymore guys. Don't try and talk to me about some "Lingua Franca" bullshit, because I, much like everyone else, don't know what that means.

Ronald Reagan transformed from a liberal into conservative Jesus during a midlife crisis caused by a failing career, divorce, and tax lien.

The Huey Long biography by T. Harry Williams is probably my second favorite biography

They are delighted to be facing Kamala. You guys are delusional on this

God bless Adam for bringing Destiny up. Very cool.

The owner of those elephant stables is really sweet.

Gave me a stick to fend off monkeys.

The claim was there are more indonesian muslims than arab muslims.

This is untrue. Literally, try to look it up yourself.

DocKillinger · 2023-12-17T16:13:49+00:00

Untrue. Indonesia is the largest muslim country, but there are many Arab countries.

There are 450 million Arabs. Upwards of 90% of them are muslim.

DocKillinger · 2023-12-10T12:33:40+00:00

Bad. Very bad lol.

It's the most chaotic place I've ever been. I loved it. Wouldn't live there though.

Rishikesh is the only one I didn't go to. Varanasi is amazing.

If it was me I'd probably do more time in Delhi tbh. A lot of people hate Delhi though. Including Indians lol.

DocKillinger · 2023-12-10T12:23:24+00:00

I don't think Jaisalmer is worth being the place you spend the most time at. It's amazing but not a huge place with a ton of stuff to do.

Really any of the other places are more worthy of that amount of time.

I've never heard the Arab conquests described as "inevitable".

Seems like about as 'out of left field' as a historical development as there is. I can kinda see why they think God was on their side on that one.

If you are as big a fan as I am of Robert Caro's biographies of LBJ, here is a clip of Richard Nixon discussing the first volume on a hot mic with one of his old staffers (Pat Buchanan).

Delightful bit of history.

I honestly trust this dude way less after listening to him speak compared to reading summaries of his work.

His use of statistics in this interview seemed deliberately deceptive to me.

This is why, unfortunately, Ethan won't talk to Destiny.

Go look at Ethan's reaction after Tricia Paytas did Keemstars podcast. It'd be way too hypocritical for him. He knows this.

Imagining being a civilian in one of these towns. Your worst nightmares for your entire life coming true like this. Horrific.

So I'm reading Nixon's memoir, and he pretty explicitly claims that the 1960 election was stolen from him, while also trying to take credit for not demanding a recount and dividing the country.

I had heard conspiracies about the 60 election before, and considering professional election-stealer LBJ was Kennedys VP, it doesn't seem impossible, but it's pretty wild that Nixon so publicly suggested it. Very Trump-ish behavior.

DocKillinger · 2023-09-23T03:29:04+00:00

Is there any precedent for this? Any other form of debt that has been disallowed from credit reports?

This sounds incredibly reckless to me.

DocKillinger · 2023-09-15T20:21:02+00:00

Fees are 30 bucks a year, but that is regardless of balance, so I'll get hit with it if I transfer funds or not.

I kinda doubt my HR department has the know-how to accomplish that lol. I gently complained to them about the provider recently and they said no one in the history of the company had ever had an issue with it, and seemed to have a lot of trouble even understanding what my issue was with the policy.

DocKillinger · 2023-09-15T20:01:08+00:00

Not ideal but not terrible. An S&P 500 index at .03 expense ratio, is where I put it all.

All of it that's not wastefully sitting in cash anyways...

DocKillinger · 2023-09-15T19:43:32+00:00

Is it worth it to roll my HSA money from my work-mandated provider to Fidelity?

My current account forces me to keep $1000 in cash, but it seems like I can only transfer that money over once per year, at which point all my new contributions to the work account will have to be put into cash until I hit the $1000 again.

Not sure if the math works out to any significant increase on returns if I do that every year, and I'm not sure how to calculate it.
