DLink DIR-615

I've just spent about an hour on DLink DIR-615. This piece of ... hardware just didn't want to establish PPTP connection with my provider (BeeLine). Luckily after about two hours of tambourine dance, I'm on-line... Firmware update from 3.02RU to 3.03RU solved my problem. And I can't find how to enable telnet access on this device. It's awful - I have to configure router using my browser...
At least, this device has a very pleasant price - about $50. This is its best feature...

ZFS snapshots or something new on something old

Everyone knows that snapshots are fascinating feature of ZFS. Automatic snapshots in OpenSolaris used to save my mental health. After migration to FreeBSD I thought "It would be easy. There are a lot of decisions for managing ZFS snapshots in FreeBSD". In fact, theare are too many decisions for managing ZFS snapshots in FreeBSD. It's hard to choose one decision. I've looked for example, on sysutils/zfsnap, sysutils/zfs-snapshot-mgmt... But my needs are quite different:

• I'd like the decision for making automatic snapshots to be simple and effective as an axe.
• I'd like to understand how every line of these scripts (for creating and deleting snapshots) work to feel myself comfortable.
• I'm going to use snapshots on my home desktop, and I'd only like to have quite recent copy of my data to recover files after making some silly mistakes.

At last, I decided to create my own solution which was supposed to work as rc script (I boot my computer once or twice per day, and it would be good to have startup snapshot of the system).
The text of script is provided below.

#!/bin/sh

. /etc/rc.subr

name="zfs_snapshot"

start_cmd="create_snapshots"
stop_cmd="drop_snapshots"
zfs_pool=${zfs_snapshot_pool:-"zpool"}
keep_days=${zfs_snapshot_keep_days:-30}

create_snapshots()
{
  echo "Creating zfs snapshots..."

  if [ -z "${zfs_snapshot_filesystems}" ]; then
     snapshot_filesystems=`zfs list -H -o name -t filesystem`;
  else 
     snapshot_filesystems=${zfs_snapshot_filesystems};
  fi

  
 
  DATE=`env LC_ALL=C date -j "+%Y_%m_%d-%H:%M"`
  for fs in $snapshot_filesystems ; do 
   snap="${fs}@AUTO_${DATE}"
   logger -t $name "Creating snapshot $snap"
   zfs snapshot $snap
  done
}

drop_snapshots()
{
  echo "Destroying old automatic zfs snapshots"
 
  current_date=`date "+%s"`
  if [ -z "${zfs_snapshot_filesystems}" ]; then
     snapshot_filesystems=`zfs list -H -o name -t filesystem`;
  else
     snapshot_filesystems=${zfs_snapshot_filesystems};
  fi
 
  for fs in $snapshot_filesystems ; do
     snapshots=`zfs list -H -t snapshot -o name -r $fs |grep "^${fs}@AUTO_"`;
     for snap in $snapshots; do 
       creation_local=`zfs list -H -t snapshot -o creation $snap`
       creation_real=`date -j -f "%a %b %d %k:%M %Y" "${creation_local}" "+%s"`
       
       eval creation_minus=$(( ( ${current_date} - ${creation_real})/3600/24 ))
       if [ $creation_minus -gt $keep_days ]; then
         logger -t $name "Destroying snapshot $snap"
         zfs destroy $snap
       fi
     done
  done

}

load_rc_config $name
run_rc_command $*

There are three parameters for my script - zfs_snapshot_pool, zfs_snapshot_filesystems and zfs_snapshot_keep_days. First or second parameter may be used to specify pool (and all its FS for creating snapshots) or explicitly selecting necessary filesystems. Parameter fs_snapshot_keep_days determines when snapshot is considered outdated.
This simple script is supposed to make my life more comfortable...

Is our favourite government fucken crazy?

It's not a dream of some moron, it's real bill. Hail to Mr. Mikhalkov and Mr. Putin! It seems some ancient morons created quite idiotic law...
1) We have to pay 1 % from the cost of CD/DVD disks, Hard drives and other "data stores" (материальные носители) for some organization which distribute this money among authors.
2) This organization is not even formed.
3) And what if I use my flash stick to backup my home directory or to carry my own presentation or even to setup Ubuntu or FreeBSD on it?
5) And if I've paid this taxes in the store, could I freely distribute copies of some good film (not Mikhalkov's one, but something really interesting)? It seems not. Some contradiction...

If I buy a new flash stick, it will be more expensive by 10-30 roubles (about 30 cents - $1). Not much. But if we summ all these money, we have a good amount to steal.

Hail to our government! The next thing we need is a tax on the amount of trees in the garden. And these taxes we will spread between.... let's suppose... agronomists (they created seeds for you... You might have bought these seeds but who cares).

Chromium was added to FreeBSD ports tree

Chromium was added to FreeBSD ports tree. I'm going to try it... Currently I use Konqueror, but it is not always perfect. And Firefox wants too much memory, works quite slow and (the most annoying for me) doesn't look good with KDE :)
