If you’ve already got a bucket ready to roll for this sort of thing, S3 is cheap, straightforward, with a stable interface and API, ownership over your assets, and a much lower chance your content will end up placed on-page and strongly associated with stuff that isn’t yours.

I truly don’t understand downvotes here. Imgur’s fine; S3’s fine; different people have different use cases. How is that contentious?

Downvotes are not for disagreement, they are for demoting off-topic or otherwise unhelpful conversational threads.

This non-rounded numbers make people think that there's something terribly important at being X degrees and not X+1, not realizing that the internal temps vary widely even when set specific. I feel recipes have caused more people to avoid cooking than anything invented in the last 1000 years, heh.

With regard to recipes, I sometimes wonder if "round numbers" are causing us to miss out on more optimal recipes. Maybe that dish really would turn out better cooked at 176F, or with 1 and 7/16 cups of flour instead of 1.5.

neither your oven's thermostat or your measuring cups are precise enough for either of those examples to make any difference.

recipes routinely call for "1 large egg". think about the amount of variance that can be present in that measurement, and assume every other measurement can vary by the same amount.

Given how many Lack tables I've seen fall apart without any sort of load, I would be very reluctant to try this, no matter how many people report it works for them. It's IKEA's cheapest table for a reason.

I currently have two stacked Lacks acting as a cheap homemade server rack. I have 2x 4U ontop the bottom table (not floating as they're doing in the article), with an older colour laser printer and 21" monitor, KVM, etc. on the top table. Underneath I have 2x1500VA UPSes.

It's been that way for years and I've moved it a few times. I think if you've seen them fall apart without any load, they're either the much newer ones that have been completely hollowed out, or they've been used in a rougher setting than "servers sitting statically on them for years."

I know quite a few home lab users who swear by them. One person I know even has a full triple stack (which seems unsafe to me personally) with his networking gear on top of the servers.

I feel like everyone else is using a different Lack than I've seen at IKEA, they're made of flimsy fiberboard that feels like it's going to fall apart at any moment. I tried making a printer enclosure and gave up because it felt like it would collapse from a strong breeze. If you're going to put in all this work, you should probably use better materials from the beginning.

they're made from flimsy fiberboard, but if you actually crack one open you'll see that all the joints are reinforced with wooden blocking, and the flat surfaces are filled with corrugated material. they're light, and if you get any water past the exterior finishing they disintigrate. but they're deceptively strong as long as all the joints are screwed together tightly.

Is this just a random coincidence? Is there some explainable reason why the dimension is perfect? Surely IKEA did not have this use in mind when originally designing this?

I've kind of hoped some manufacturer would clue into this as a possible side benefit to their design of furniture. But the 0.0000001% of humans who want a rack at home are probably not a substantial market, so my guess is this must have been happy coincidence.

On top of that, Imgur automatically deletes EXIF data, which would've prevented GGP from leaking their home address.

This touches a semi-related nerve. When you share a photo on iOS there’s an option to remove exif data—or at least the photo’s location—but there’s no way to always have it removed by default. Really annoying and easy to forget. /rant

I think that you can at least choose for photos you take to not have location data at all in camera settings.

I found out because the feature of mapping of where your pictures where your pictures were taken did not work for me, because I stopped the camera from having location data.

When it comes to flour, I don't understand why the USA insists on measuring it by volume when the rest of the world does it by mass. The density of flour can vary widely depending on if it's packed at all, and scooping it often leads to voids in the bottom of the measuring cup that you likely won't see unless you're using a clear measuring cup. When using flour or baking mixes, I convert to grams (1 cup all-purpose f…

Every American kitchen has measuring cups, few have scales. And people learn that method and continue to use it (most people don't even know about zeroing a scale after you add each ingredient). It may also be that US measuring cups are "more convenient" sizes than the equivalent metric ones would be. For flour, they often specify "sifted" which removes some of the variability.

> Every American kitchen has measuring cups, few have scales.

There's no reason Americans can't buy scales.

I got mine for $15 at Costco 10+ years ago. You can still get them from Amazon or Walmart for less than that.

> It may also be that US measuring cups are "more convenient" sizes than the equivalent metric ones would be.

When measuring out flour, I don't use a measuring cup at all. I put a bowl on my scale, hit the Tare button to zero it out, then add whatever number of grams of flour I need to the bowl.

That's gotta be awkward to sift into a measuring cup.

hard to imagine someone stooping to this level of antagonistic misrepresentation because they disagreed with someone else’s preference for image hosting, but there it is. “two clicks of a mouse” - that’s a negative, not a positive, attribute.

I have been really happy with the HEJNE shelf as a rack. Here are some 2U's here at home: https://s3.whalesalad.com/lab/rack.jpg The shelf: https://www.ikea.com/us/en/p/hejne-shelf-unit-softwood-s7903... I keep seeing full height Dell racks for sale on FB marketplace in the $200 range but haven't encountered the right manic episode to actually go for it.

It's not the rack that's the problem, it's the fans. Most industrial gear requires a ton of airflow and the noise is something like having a model jet engine sitting in your closet. This from someone who actually did go for it and later recanted.
