This is my understanding, please correct if it is not true. If it is possible to train neural with a batch method, we should explain that. Also I believe that...

Investigate case of empty chunk

In #80, I noticed that when logging a long message, in `toBufIOWith` there comes around a `Done` with `len == 0` as the first thing before the real data comes....

Thanks for this tool! It works great for my `GS108Ev3` and `GS105Ev2` switches. However, the `GS108PEv3` (with `P` for "Power over Ethernet", PoE) is not found by the `scan` command....

My program just crashed at run-time with ``` ghc: Duplicate version tags: [2,2,1] ``` because I wrote ``` haskell deriveSafeCopy 2 'extension ''Mytype_v2 deriveSafeCopy 2 'extension ''Mytype_v3 ``` when I...

I tried to tell `pv` to make large `read()`/`write()` sycalls (it is much more efficient to make large syscalls on e.g. networked file systems) using `--buffer-size 16M`. However, I found...

Use pidfd to track processes on Linux >= 5.4

Background: * https://lwn.net/Articles/789023/ * https://lwn.net/Articles/794707/ The problem `Pid`s in [`ProcessHandle`](https://hackage.haskell.org/package/process-1.6.10.0/docs/System-Process.html#t:ProcessHandle)s is that on most system they are limited to 2^16 many by default. If you spawn many short-lived processes quickly,...

Discussion: High-level functions that can convert between vector types

**Edit:** Issue description of the underlying problem https://github.com/haskell/vector/issues/373#issuecomment-808821411 Below is the original question that led to it: --- I often work with indices that I'd like to store in `Unboxed.Vector...

`man utimensat` doesn't document it (at least on Ubuntu 16.04 -- but [this page](https://www.mkssoftware.com/docs/man3/futimens.3.asp) seems to do for `futimens`), but it seems that `utimensat()` can return `errno = EINTR` when...
