| 00:42.15 | DocScrutinizer05 | well, aiui it's a question of parallelizing spam filtering. I don't see why this needs any particular number of preforked processes, except for performance optimization. when there are >25 concurrent inbound mails, they will need to get processed in a serialized way, which is what my system's spamd does anyway |
| 00:44.33 | DocScrutinizer05 | I'd think "hitting the `limit´ " is pretty normal for this sort of things |
| 00:45.12 | DocScrutinizer05 | actaully _not_ hitting the limit ever would raise concerns |
| 00:50.31 | DocScrutinizer05 | it's not like infinite number of child processes would boost system performance to infinity too. Rather the system eventually hits other limits and a 50 processes that tun from swap are for sure several magnitudes slower than a 25 processes filtering same amount of data in a serialized way within RAM rather than spinning circles in swap hell |

| 01:13.25 | DocScrutinizer05 | timeless: however I noticed spamd getting incredibly slow during last maybe 12 to 24 months, must be something about internet connections to servers with spam blacklists or whatever |
| 01:15.24 | DocScrutinizer05 | maybe investigating what exactly is going on, and possibly setting up a transparent proxy or (if spamassassin supports that) a local database cache, might be worth it when you run a system where you need >25 concurrent instances to process all your inbound mail |
| 01:18.22 | DocScrutinizer05 | as a ballpark figure reference, my spamd seems to take random amount of time between 0.5s and sometimes 20s for filtering one email. A 2 or 3 years ago I witnessed it filtering a maybe 20 mails per second, sustainably |

If you have a GUI (X Window System), programs such as WinDirStat that use a (squarified) tree map to visually represent how space is used in a file system are useful too. Yes, WinDirStat is a Windows program but similar programs are available for *nix (GNU+Linux). |

| 19:20.42 | Enrico_Menotti | I'm going to ask a few questions about kernel building, in particular building a single kernel module (a new module to be added to the system). It's a bit off-topic at the beginning, but since my aim is to see whether I may add a couple of modules to the Maemo kernel, maybe it's not that wrong to ask here. |
| 19:22.59 | Enrico_Menotti | First a general question about building the kernel: when I did that for Devuan, I learnt that the first thing to do is to call make against a "pre-cooked" config file, like make rx51-defconfig. Then one may simply invoke make to build kernel (+ modules), or call make against menuconfig, for tweaking the configuration, before actually building the kernel. |
| 19:26.44 | Enrico_Menotti | Now I was trying to prepare a configuration from scratch. For that, I invoked make menuconfig as first command, and saved the configuration to a file named ".config". Then I tried make, which didn't work, or make .menuconfig, which didn't work either. By googling a bit, I have found that I have to call make oldconfig and make prepare before making the kernel. That led further, but I had other errors about some |
| 19:26.44 | Enrico_Menotti | <PROTECTED> |
| 19:28.29 | Enrico_Menotti | Al this allows a build (really I didn't build the whole kernel, I tried with a single subdirectory, containing sources of a driver.) But I have to admit that I don't understand the various steps I had to take. If anybody could explain or point to an explanation, I'd be happy. |
| 19:30.36 | *** join/#maemo err0r3o3 (~err0r3o3@193-80-112-98.hdsl.highway.telekom.at) |
| 19:39.09 | Enrico_Menotti | Now my real point is how to build a single kernel module (without having previously built the kernel). Seems this may be done by cd'ing to the module directory and invoking make -C $(KERNEL_SRC) V=0 M=$$PWD, where KERNEL_SRC has been defined as /lib/modules/$(shell uname -r)/build. I'm on Devuan on an x86 machine, so KERNEL_SRC really is /lib/modules/3.16.0-4-686-pae/build. |
| 19:40.00 | Enrico_Menotti | If I got it correctly, I could as well cd to KERNEL_SRC and invoke make V=0 M=<module directory>. Is this correct? |
| 19:42.12 | Enrico_Menotti | Also, I don't know what V=0 is. But will investigate about that. In any case, my main question is: what is there in the KERNEL_SRC directory? I didn't install any kernel sources, but I find there some directories which remind me of (some of) the directories which are found in the kernel source tree. |
| 19:44.28 | Enrico_Menotti | Last thing: this would produce a module for the running system. What if I want to build a module for a different kernel (specifically, Maemo kernel)? Is it enough to substitute for KERNEL_SRC the path to the kernel source directory? Do I need to invoke some make <something> before building the module? |
| 19:45.28 | Enrico_Menotti | Thanks in advance for any answer. |
