Patching rc.firewall with modprobe -l

A little note to myself:

Since ~2011, the modprobe does not include -l (--list) function anymore, hence we need some workaround to some of our scripts that rely on that function. A trusty script made by wand [at] users.sf.net, rc.firewall was affected by this change.

The solution is to replace the function by a new one. For rc.firewall case, it can be replaced easily by lsmod.

These are the lines that we changed:

  for MODULE in $REQUIRED_MODULES; do
    #modprobe -l is depreciated, and replaced by
    #lsmod
    #orig:
    #if (( `modprobe -l | grep -c "$MODULE"` )); then
    #changed to:
    if (( `lsmod | grep -c "$MODULE"` )); then
      modprobe $MODULE > /dev/null 2>&1
    fi
  done

For one who need a similar output of modprobe -l, we can use this function:

    find  /lib/modules/`uname -r`/kernel -type f -printf '%f\n'

A patched rc.firewall with lsmod is available here.

Bermula dari jebolnya komputer pribadi yang digunakan untuk layanan e-learning dan repositori abstrak skripsi bagi institusi tempat kami mengabdi, petualangan menyambung nyawa komputer tua dimulai. Spike  listrik adalah biang utama rusaknya perangkat ini. Ya, sebaiknya perangkat elektronik perlu pelindung dari lonjakan listrik sekedipan mata yang mematikan. Komponen yang menjadi almarhum akibat spike  kali ini adalah VGA card dan tombol reset (kok bisa, ya?).  VGA card Radeon X1300 128 MB Komputer ini sudah cukup tua usianya, sekitar 9 tahun. Motherboard-nya Intel DG31PR dengan prosesor Intel Core 2 Duo E7500 , memori DDR 2 3 GB dan harddisk SATA 500 GB 7200 RPM.  Sistem operasi yang digunakan adalah Slackware Linux  versi 13.37. Kinerja komputer ini sebagai server e-learning untuk kategori dosen jelata macam kami sudah cukup memuaskan. Sekitar 80 orang pengguna dapat dilayani secara simultan, walau bottleneck -nya tentu saja di hard-disk dan wifi seputar ruang lab.

Writing and reading float using Arduino EEPROM

This post is just for a personal reminder after reading discussions from elsewhere about storing and reading float values to/from EEPROM with Arduino. Scenario Writing negative float to EEPROM can be tricky, since EEPROM only recognises up to 8-bit values (see Tronixstuff  explanation ), therefore it requires an additional algorithm to make it able to store negative and float.  the scheme is to use four bits of the ATmega328's EEPROM to store numerical parts of a float value. The function involved is union . //union  value typedef union{   float flt;   byte array[4]; } FloatConverter; The code You may grab the code here

Past articles: NTC thermistor incubator (part 1): connecting triple thermistor NTC thermistor incubator (part 2): multi-buttons input for single Analog pin   Introducing CodeBender Today I found a great code sharing website called codebender  that allows me to use Arduino in any computer since it has online IDE with crossplatform browser plugin to upload to Arduino system. Remember, Arduino is an Open Source Hardware project, I encourage people to share as much as we learn from others too. Sharing knowledge is awesome! Since everything is online and pretty straight forward, I will try to explain my project as simple as possible. The Aim My aim is still to produce an incubator, but today the specification will be: Internal LM35 temperature sensor that will be placed inside the incubator External LM35 temperature sensor that will monitor ambient/room temperature Peltier element that will be connected through a relay module Displaying internal (current temp, CT), e
