What makes a motherboard a NAS motherboard, precisely? I've got a decent Mini-ITX sitting around and I've been contemplating setting up/getting a NAS. Would be nice if I could re-use what I already have and save some money.


Technically any motherboard can become a NAS, but there are desirable features.

- low idle power consumption since your NAS will be sitting doing nothing most of the time - pretty much any desktop MB will do

- fast networking, 1gbe means ~100MB/s transfers, nicer to have 10gbe. Limited benefits beyond 10gbe in practice.

- enough PCIe lanes to connect enough drives. HDD of course but nice to have a separate fast SSD array plus SSD caching. You might also want a SAS HBA if you are looking enterprise drives or SSDs (and even for SATA SSD you will get a better performance via a HBA than through the motherboard). Some people also want a graphic card for video transcoding

- ECC memory

- IPMI - once you start using it it becomes hard to give up. Allows you to manage the server remotely even when switched off, and access the BIOS via a web interface. Allows you to keep the server headless (i.e. not have to go plug a screen to understand why the server is taking so long to reboot).

I'd say a good candidate for a NAS motherboard would be something like a supermicro X11SSH-LN4F, you can find used ones pretty cheap on ebay.


For me, ECC RAM, large enough number of SATA ports, ability to run rest of my software stack well enough (in my case FBSD and ZFS).


Very interesting. Almost feels like a cosmic implementation of "If a tree falls in a forest and no one is around to hear it, does it make a sound?"


Am I missing something or is the author using dots for both breaking up large numbers and also for decimal points?


Yes, I assume it is because you use dots to seperate large numbers in most European languages and they forgot it's different in English.


usually its a combination of . , not exclusively . for both the thousands seperator and the radix point.


Well, they appear to have remembered it when typing the radix point, but forgot it when it came to the thousands separator.

This might have happened to me before as well...


The Haskell looks much better, and I don't even know Haskell.

Surely "if you know Haskell it's easy" is equally applicable.


> The Haskell looks much better, and I don't even know Haskell

Plain crazy take. The c example uses basic coding to implement some clever maths with special fast instructions. Thehaskell example is just some dumb algo implemented with complicated programming. There is obviously nothing good about that.

You can also look at a c example without simd https://benchmarksgame-team.pages.debian.net/benchmarksgame/... It’s shorter and simpler and faster than the Haskell version. It’s not even close???

Really? Mine lumps together completely unrelated people whilst failing to group together the same person.


I have pages of notes for a game like this that I've been thinking about since university, largely inspired by Battlestar Galactica and The Expanse. This game reminded me of it too, maybe I'll get to it one day.


DynamoDB is used by Amazon.com.

"Across the 48 hours of Prime Day, these sources made 7.11 trillion calls to the DynamoDB API, peaking at 45.4 million requests per second." [1]

You're forgetting specifics here and the amount of hardware resources thrown into it. I've already told that I am not discussing here FB/Google/Amazon scale stuff. It is their problem and not shared by more regular deployments


TIL: A day has 48 hours at Amazon.


The same day across multiple time zones could take 48 hours


Of course Amazon would call that an Elastic Sundial.

Why does the Southern US seem to contain the highest concentration of North-South runways in the world?

It has to do with prevailing winds. Thanks to the Gulf of Mexico, winds in the eastern half of Texas and the surrounding states pretty consistently blow south to north.


Broken on Windows too.

You can use arrow keys


More precisely: click on the sidebar and then use the arrow keys.


Couldn't get arrow keys (or scroll) working on FF on Windows. If you select text and drag to select, the screen scrolls.
