In my experience, even cheap IKEA stuff is pretty solid and well worth the cost as long as you treat it with care. Some stuff is garbage even if you're careful but I've never personally seen something from IKEA that isn't great if handled gently.

In my experience, you get one move from IKEA furniture. By the time you've relocated it twice, whether across the room or across the country, it will become unstable and likely to fail. If you are exceptionally careful and always have help moving anything of size, you may do better.

My dad was a cabinit maker so i have experienced "proper" cabinets as well as Ikea stuff.

You called it. Ikea furniture never seems to support disassembly / reassembly.

I've thrown out several sets of Ikea dressers and such which lasted ~5 years while the stuff my dad built is still in perfect working condition 22 years later.

As far as the Ikea rack idea is concerned, holding any sort of weight has always been the major failure with Ikea furniture. They sell bookshelves which cant hold books... Dressers with 1/4 "cardboard" bottoms which cant support the weight of clothing.

you get what you pay for.

You know you are in HN when people use S3 to upload photos, and not imgur.

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?

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.

You find temperatures that precise when they're for equipment that can hit it: a sous vide steak at 56º C is different from a sous vide steak at 58º C. It just makes no sense for an oven, which is a pretty blunt instrument.

In the article linked at the end > https://spuder.wordpress.com/2013/03/23/lack-rack/ you can read (emphasis by me): "If you decide to make your own, pay attention to which size lack rack you get. IKEA strangely offers 2 slightly different sizes 22 inch and 21 5/8 inch." In my opinion the explanation for this is clear: 22 is a round number in inches and 21 5/8 inch is nearly a round number in centimeters (21,625 inch…

Edit: Nope, just didn't scroll far enough. They also list the 22" on their site as well. But still, which size is best for mounting?

old: The IKEA website only lists the 21-5/8" version. Is 22" required for computer rack use?

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?

It's a round number of inches that happens to be right, possibly because "this size is good for a table" is what probably went through the engineer who decided what size a rackmount should be at the beggining of time

I don't think it's inches. This is a Swedish product. The tables I have from Ikea measure 55cm from what I recall. The legs are 5cm wide.

can somebody with more server/home server experience explain to me the benefit of going with a rackmount setup vs let's say, just building a second PC to use as a home server? I recently bought a house and am excited to get into home networking/home server work, but don't know anything about rack mount. Is rackmount equipment cheaper than regular consumer PC hardware?

There has been a number of solid responses but my two cents.

It isnt about the "form factor" - but the cost. Businesses buy rackmount servers because it is space-efficient.

Eventually they sell these off very cheap and unlike your desktop grade equipment business servers are built to last. while that 5 year old business server may be out of date for them, they still have plenty of life left and can be had for dirt cheap.

i have a multimedia server in my basement with 72GB ram and dual Xeon's which i picked up for around the cost of a decent desktop motherboard.

So in short. Rackmount equipment purchased brand new is very expensive, but buying old "end-of-life" gear is very cheap. The depreciation on computer equipment would put a car to shame.

> and you can put your bottle of Club-Mate Damn it, now you're really making me pine! Why must this stuff be so hard to get in the US? Last I checked there were two different companies handling distribution in the US and NEITHER of them seem to stock it anywhere! Except for one shop in LA that half the time carries expired bottles! The caffeine high from Club-Mate is such a pleasantly sublime feeling. And you used to…

Amusingly, even thought I live in Berlin and have it readily available, I tried to make it myself by making mate concentrate, sugar, and a tiny bit of lemon. I got the taste just about right, but more mate-y with the really grassy, earthy taste of mate. But it had so much caffeine that I couldn't think straight and felt jumpy. I came to the conclusion that Club Mate doesn't actually contain much mate.

But if you love the stuff and can't get it, it's not hard to experiment. Those are basically the only ingredients.

Oh boy is this thread relevant to me. I just bought a concrete paver and neoprene mat to put on top of my lack and I'm printing pieces for my lack enclosure on my ender 3 as I type this message. One thing I'm not sure about is whether or not I should attach the printer directly to the concrete paver, and/or if I should take the rubber feet off of the printer as well. If so how do I best attach it?

I have a 3-lack-stack for my printer, but no paver. It sways a bit when I print, but I haven't run into any major issues without it. I should get one. A foam mat was mandatory though; the hollow core lack turns the motor noise into a scream! I'd just try the easy thing first and set the printer on the paver without attaching. See if that works before you go through the effort of attaching it

The motor noise can be totally eliminated with an upgrade main board from bigtreetech. https://biqu.equipment/search?filter.p.product_type=3D+Print...

They are drop in replacements for the existing board and are very affordable. I highly recommend them.

> Is rackmount equipment cheaper than regular consumer PC hardware? Not even close for new, but a generation or two old can be had very cheaply. I was was once gifted a 128 node cluster (with the racks, UPS, everything) to a lab for the tax write off alone - they even provided shipping. The servers were only 3 years old iirc, but had depreciated enough on their books I guess and they wanted a faster cluster.

Shipping and write off is much cheaper than disposal.

I recall as college students finding a VAX 780 on the "getting rid of it" part of the engineering loading dock and we got permission to get rid of it for them. Pushing it down the street at 11pm was interesting (getting a weird look from a police car going by).

It got gutted for parts (power supplies don't care too much about what they power) and converted into a lockable bookshelf and 14" diameter wall hangings (and some surprisingly strong magnets).

The "yea, we let a bunch of college students take it" was a significant savings over getting a truck to haul it off to some junkyard even before the days of being very picky about electronics recycling.

Because some folks can’t distinguish between contextual value judgements based on their own preferences, and a universal absolute.
