It still has an issue with getting stuck in a bad state if you let the free space drop too low (e.g. under 5% / 2GB). It might still be recoverable but it takes a lot of fiddling and work to do that.

In the US, a lot of car dealerships make a good portion of the profits from a car sale from the loan. E.g. the lender gives the dealer a kickback on the loan and that is a good portion of the total profit. It's somewhat analogous to how US airlines make their profits from credit card deals and selling miles.

That failure mode is still there although it's been mitigated a bit. I hit it a few months ago but was able to recover after a few hours of doing various stuff.

Well, not selling controlling majority stake is fine. What people have issues with are the super-voting rights that where the people owning those rights get to play with other's money with the others not having much say on how that money gets used. E.g. look at meta's VR spending as an example.

It's been around in slang for a few years with a few variants, e.g. "I haven't seen her in a hot minute." I think it's just filtered into wider cultural vernacular.

It seems that btrfs is being phased out of fedora. It looks like Fedora will be moving to stratis storage over the next year or two. Btrfs is nice but it's raid5/6 support still seems shaky and there's odd corner cases that apply to all btrfs setups (getting stuck when free space is low is mostly resolved but can still occur).

If a founder is going to VCs or the markets in general for funding, there's no way to really do this. I don't see how the vast majority of founders can realistically expect others to fund their companies and still let the founder have the final say on all company matters.

If founders are willing to self-finance or finance based on cash-flow/collateral, that's a different story. But if you're selling majority stakes of your company's equity to others in order to finance your operations and growth, the equity owners should get a majority vote in how your company runs.

And FB is a lesson to a lot of companies and the public not to allow the same dual class stock structure. Zuckerberg can cash out a lot of his equity and still be the controlling force behind FB even though other people "own" a majority stake of the stocks and equity.

Iran had a pretty strict P5 agreement under Obama that would have prevented Iran getting nukes for sanctions relief and other benefits. For some reason, a president decided to toss it for no apparent benefit.

Trump literally said a day or two ago that if Iran had nukes, he'd treat them a lot nicer and would cozy up to them like with China, Russia, and North Korea. Given that what government wouldn't serious consider obtaining nukes if only as a matter of survival?

The following wiki article has a section on it. Cluster munitions allow you to saturate areas and prevent infantry from advancing. The issue is that some of the submunitions malfunction and sit around on the ground and injury civilians (particularly children since they look like toys at times) https://en.wikipedia.org/wiki/Dual-purpose_improved_conventi...

Could be due to better control of blood sugar. E.g. lower blood sugar increases inflammation, decrease immune response and provides bacteria a readily available source of food.

More to the point for Guam and similar locations, canned and non-perishable food can are probably around and more can be airlifted in to get people through it. It was pretty much the standard back in the day.

The dedup functionality in something like zfs or btrfs isn't all that great. It tends to be extremely memory hungry and to slow things down significantly. E.g. ZFS needs around 1-5GB of ram per TB of storage and writes need to be compared to a hash table to dedup properly.

Using hints or knowledge at the app level is a much better experience if the app can tell the FS that two files are identical. The FS doesn't have to worry about hashing blocks within the file, correcting alignments, etc.

scheme271 — Thu, 27 Aug 2026 04:44:53 +0000

The pause is for immigrant visas so most visas like H1 or H2 or O visas aren't affect this time. But it's definitely part of the US admin's overall theme of ratcheting up visa restrictions and making any immigration or travel to the US extremely difficult.

There was another similar flood on the same river about a year or two ago. The problem was the the glacial flooding started in Tibet and affected people just over the border (one of the videos is from the border crossing). There's no international data sharing for this sort of thing between China and Nepal and Nepal can't deploy sensors in Tibet to give sufficient warning.

North Korea isn't doing so well, but it's doing better than Iraq, Libya, or Venezuela at least as far as the leadership is concerned. Their conventional forces being within artillery range of Seoul probably helps but having multiple credible nukes really has helped them to avoid being a target of regime change.

I think they are the same with some software differences. I believe that the sampling rates and tolerances are different. For example, dexcom displays 5 minute samples while the stelo shows 15 minute averages (it internally gets a new sample every 5 minutes like the dexcom). I think the official accuracy is a bit lower for the Stelo as well, although in practice it's probably close to the dexcom.

There's some difference in the readings of a CGM due to sampling different things (blood with finger sticks vs intercelluar fluid for a CGM) and taking a bunch of vitamin C (pills or in food) can throw the readings off. But I think one or two sticks a day to calibrate the CGM and in situations where readings seem off should be sufficient.

Anyone with type 1 diabetes is injecting while outside the home. Usually it's a long acting baseline insulin that you can inject at home and then a faster acting one that you inject before eating or drinking anything that's not water.
