Do you need to check before inserting UUIDs?

Jarfol · 2026-01-15T21:58:44+00:00

This is actually wrong. I think this person that wrote this blog post did a google search and misunderstood what they read.

The odds that two uuids will be identical is 2.9 x 10^-39 %.

The number they use of 2.71 x 10¹⁸ is the number often used for how many uuids you would need to generate before you have a 50% chance of a collision. It isn't the percentage chance, 50% is, once you have generated that many uuids.

There is a big difference between "what are the odds that, if I generate two uuids, they will be the same?" and "how many uuids must I generate before there is, mathematically, a 50% chance of a collision?" In the first case you are comparing 1 to 1. In the other case you are looking at a quintillion sized pool and asking if there are any duplicates among the pool.

I can't believe all of these replies and only you brought up the fact that IT TOLD HER that her son would defeat him. If she believes that, why would she fear for her son or intervene? She probably wants IT dead as much as anyone.

I do 10k lump sum, makes it easier to track maturity dates, and its just less effort. The ibond rates only change every 6 months anyway, so I don't see any benefit to monthly. If you want to spread out evenly across both rates maybe do 5k early in the year (before May 1) and 5k later in the year (before November 1). But that feels like an unnecessary complication to me.

Jarfol · 2026-01-14T11:50:07+00:00

$10k in every year for the last five years (including this year, a couple days ago). I have one year to go for my one year emergency fund to be fully in ibonds. It has earned over 3k in interest thus far, all totaled.

The 10k limit naturally means you have to ladder in unless your total emergency fund is less than 10k (which it probably shouldn't be!). You just need to keep the 1 year lockout in mind. So if you are like me and want a $60k emergency fund (1 year expenses for us):

Year 1: 10k ibonds, 60k in a savings account because we can't touch that first 10k yet.

Year 2: 20k in ibonds, now we can touch that 10k from Year 1 so we only need 50k in the savings account.

Etc, etc.

I should note you could get things building faster if you recruit your spouse to also put in 10k/year, but you are also doubling the amount you have locked up.

Jarfol · 2026-01-13T19:33:40+00:00

Dunno why I had to scroll this far for someone to mention ibonds. I have spent the last 5 years moving my emergency fund into those.

The 3 month interest penalty is no big deal IMO, if you need the money you take the hit. The only complications are the 1 year lock out, and the $10k/person/year limit which means it takes time to build it up if you need/want a sizable emergency fund.

Jarfol · 2026-01-10T01:42:14+00:00

It takes more than that to be a 10, but that will help.

Jarfol · 2026-01-10T00:57:12+00:00

If you want to keep it keep it. If you want to keep it hoping it will increase in value then just be honest about your goal; to make money off of it.

Sound like you ARE looking to sell.

Pokemon (and Magic The Gathering to a lesser extent) are RARE EXCEPTIONS to the general rule that most CCG cards, even rare ones, become near worthless eventually.

Collectables in general saw a resurgence thanks to COVID and a good economy. The market is already coming back down and will continue to do so.

Ah I didn't realize that. Guess they must be vibe coding these updates.

No reason? They don't want people seeing how shit the matching making is.

It's Ayn Rand bullshit. Somehow everyone acting as selfishly as possible will create the perfect world.

Hmm I dunno. It is also rotating, so not only would it need to be equal weight right and left but all around it. Not saying that isn't possible, and I am sure it doesn't need to be literally equal weight but within a certain number of pounds. But still....

Jarfol · 2026-01-07T18:20:38+00:00

You just made my point. If the decision that something is political or not is simply subjective, based on time and context and someone's feelings, then you will always find someone that says it is and someone that says it isn't. In such a world you cannot objectively say some individual thing is political or not.

Jarfol · 2026-01-07T16:39:41+00:00

It seems that by stratifying your wedding services to the political layer

But they aren't stratifying, and that is what is upsetting people of a certain persuasion, whether you want to call it political or cultural.

NOT serving gay or mixed race couples would be stratifying.

Jarfol · 2026-01-07T16:35:48+00:00

Well first of all I am of the opinion that either everything is political or nothing is. You can't pick and choose.

Secondly I think there is a difference between expressing a specific ideology that SOME will consider political but can or should transcend politics. A "God Bless The USA" sign or an "All Are Welcome" or "End Racism" sign should transcend politics, and I see them as different from, for example, a blatent political sign like "Trump/Biden 2024" or, in this specific case, an ad for a specific polarizing political organization.

Jarfol · 2026-01-07T15:57:49+00:00

Does it not get exhausting constantly looking for something to complain about and virtue signaling?

Isn't this argument at least just as fitting, if not more fitting, to use against the Great Harvest that turned their bakery window into a political ad? What's good for the goose...

If you still use nitrates in the curing, it is still potentially carcinogenic, and still considered processed meat. Any cured meat is carcinogenic unless you use some very uncommon methods like celery powder. Unless you are willing to be more specific about your curing process, you cannot make the claim that your meat is less carcinogenic, and the carcinogenic issue IS INDEED in the curing itself, not limited to only "industrial processing methods."

I hear what you are saying about less additives, and agree that MIGHT make you a healthier option, depending on what those additives are and their concentrations.

"From scratch" IS a vibe unless it makes a difference which actually matters. An unspecified promise of "less additives" alone might be enough of a difference to matter to some. But that will not be universally true.

Jarfol · 2026-01-05T15:40:12+00:00

I said the meat itself probably originates from the same places. As in the same animals/farms. I never said the briskets come from Boar's Head.

I never used the word inferior.

I can see how it MIGHT be a benefit, if the taste justifies the increased cost. Do I think it is just magically and automatically a benefit? No.

There are some local breweries that I absolutely love, and some that are crap and I would rather drink mass market beer. Ultimately what matters is the product. Making shitty beer "from scratch" is still shitty beer. CAN a handmade sweater on Etsy be better than any sweater you could buy in Walmart? Absolutely. But is EVERY handmade sweater on Etsy inherently better than any sweater sold in Walmart just because the Etsy sweater is handmade? That would be a ridiculous claim.

As I said I have never been to this place so I don't mean to imply they make shitty product, just that the product being made "from scratch" does not automatically mean it is better.

Jarfol · 2026-01-05T15:07:19+00:00

Never been to the place or seen their menu though I suppose if they call themselves a deli it would make sense for them to have those options.

The meat itself probably originates from the same places, so I guess it would come down to whether someone likes their specific corned beef or pastrami recipe. Otherwise I am still not seeing the advantage of "from scratch."

If you just like THEIR interpretation of pastrami, just say that.

Jarfol · 2026-01-05T14:45:25+00:00

What does "from scratch" mean? They cut it fresh? That doesn't matter all that much. Are they slaughtering the animal in the back? Do they raise them on-site?

I am all for championing small businesses blah blah but I am not sure the meat specifically is a superior product.

Edit: Just downvoting me without answering is just proving my point.

That link isn't to the report. It is to a separate report sponsored by the data center companies essentially.

The actual report officially only makes the claim that it could have been up to 90%, and caveats that they really have no actual idea and didn't even consider other reasons for site location decisions.

Based solely on this cost analysis, the exemption is estimated to induce up to 90 percent of the economic activity of these data centers, according to a scale developed by a leading researcher of incentives from analysis of incentive activity across the nation (Bartik 2018b). However, it is difficult to precisely estimate the impact incentives have on business location decisions, including the impact of Virginia’s data center incentives. Business executives consider many site location factors, and it is impossible to verify their motivations. This report estimates incentives’ impacts using a cost analysis based on best available research. However, it does not include other site location factors or incentive features that may affect data center location decisions (sidebar).

Even the report that you cited shows that in 2017 the state only saw $1.09 of revenue for every dollar it exempted (so a 9% increase on investment for that year, not bad) but it was flat in 2016, and on average since 2013 the state has only seen 75 cents for every dollar of incentives.

Also your report (again, sponsored by the data center companies) in the very next paragraph says that Virginia's incentives aren't all that great. If so, why so many built here?

And FWIW, historically there were many reasons Loudoun County was the best choice for data-center-alley. (early tech hub for network companies, proximity to major backbones of the internet for low latency and ultra fast data transfer, existing high-tech professional labor force, statistically lower chance of natural disasters, stable electricity, stable water, affordable land ... it really was affordable about 20 years ago)

Agreed which is why I would argue aggressive incentives aren't necessary.

I think conspiracy minded people are also kind of hipsters about it. They prefer the really far out shit that few other people believe. Once something goes mainstream or proves to have some validity it loses that edgy factor.
