After playing with the software a bit: The view that diffs environment variables of a process with the ones from the parent process is very nice. Could you add a feature that makes it possible to search/filter the "Environment&quo

Ah yes, very good! More such tools are needed that make common strace tasks more convenient. strace is the ultimate debugging tool to dive into almost every problem where a program doesn't do what you want, but its stream based nature

Ah, I see. I was assuming that the achievement of consistent state must somehow be achieved in the child. If the parent can achieve consistent state (e.g. doing the equivalent of pressing "pause"), why not do the following instead

How do you know that the game state is in a consistent state in the child? A stopped thread may be in the middle of mutating an array or struct.

It still seems super error prone: It is very difficult to write general purpose C++ code that does not call malloc somehere. Something fails and you want to display a message `"Error: " + reason`? Bam, malloc right here, serialisa

My experience is: Downtime does matter. Customers ignore downtime when you're a service with big lock-in or no real alternative (GitHub, Facebook, etc). Because then they can't do anything about it. When you're a small/m

While a possible explanation, that sounds extremely inconvenient, and a silly default. It's Google's own group of my own org. Does it make sense that the spam button would punish my group own email? Also, if I mark it spam in the

I'm not the person you asked, but say you have 10 TB of logs. Assuming 3 GB/s SSD, 10 SSDs, and a compression as you suggested of 10x, a query for finding a string in the text would take 10000 / 3 / 10 / 10 = 33 sec

I agree on the technical part, but: A problem is that you can do everything technically right, and sitll land in spam, because some big players don't play by the usual rules. For example, Microsoft apparently has an allowlist for IPv4

For completeness: The orignal post says: S3 has no rename or move operation. Renaming is CopyObject and then DeleteObject. CopyObject takes linear time to the size of the file(s). This comes up fairly often when someone ha

I don't quite follow the argument: > it’s on you to ensure the foreignptr’s lifetime becomes interlinked with the returned b Yes; the simplest way to do that is to make sure that your data types never contain raw `Ptr`, only `Foreig

The key difference between lexicographically keyed flat hierarchies, and directory-nested filesystem hierarchies, becomes clear based on this example: dir1/a/000000 dir1/a/... dir1/a/999999 di

If it is an NFS concept, not FUSE, then "use interrupt mounts for things like sshfs" does not really make sense, because sshfs is a FUSE program and not related to NFS.

Haskell's FFI has `withForeignPtr :: ForeignPtr a -> (Ptr a -> IO b) -> IO b` [1]. A ForeignPtr is a GC-managed pointer with an associated finalizer. The finalizer runs when the ForeignPtr gets GC'd. `withForeignPtr` crea

Agreed, it depends on the use case. For some "more storage" is all that matters, for others you don't want to be bottlenecked on getting it into / out of the machine or through processing.

First, the feature set you have built is very impressive. I think SeaweedFS would really benefit from more documentation on what exactly it does. People who want to deploy production systems need that, and it would also help potential contr

We do not require to have experience with all tech listed, but the more of it one is familiar with, the faster onboarding will be. For example, our last hire knew Haskell/Python/TS/React well, and got into C++ in our project.

What is alpha quality about bupstash? It has less features than Kopia, but what's there looks like high-quality to me. (I'm also using it to back up 150 TB (300 million files), on which all other dedup programs run out of memory.)

One reason for using Ceph instead of other RAID solutions on a single machine is that it supports disk failures more flexibly. In most RAIDs (including ZFS's, to my knowledge), the set of disks that can fail together is static. Say you
