Son olarak: ARP'ın kullanımı

C:\Users\Administrator>arp

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr] [-v]

  -a            Displays current ARP entries by interrogating the current
                protocol data.  If inet_addr is specified, the IP and Physical
                addresses for only the specified computer are displayed.  If
                more than one network interface uses ARP, entries for each ARP
                table are displayed.
  -g            Same as -a.
  -v            Displays current ARP entries in verbose mode.  All invalid
                entries and entries on the loop-back interface will be shown.
  inet_addr     Specifies an internet address.
  -N if_addr    Displays the ARP entries for the network interface specified
                by if_addr.
  -d            Deletes the host specified by inet_addr. inet_addr may be
                wildcarded with * to delete all hosts.
  -s            Adds the host and associates the Internet address inet_addr
                with the Physical address eth_addr.  The Physical address is
                given as 6 hexadecimal bytes separated by hyphens. The entry
                is permanent.
  eth_addr      Specifies a physical address.
  if_addr       If present, this specifies the Internet address of the
                interface whose address translation table should be modified.
                If not present, the first applicable interface will be used.
Example:
  > arp -s 157.55.85.212   00-aa-00-62-c6-09  .... Adds a static entry.
  > arp -a                                    .... Displays the arp table.

Ben bekarken: Mecimek Çorbasında 22.01.12 itibarıyla son durum


Lezzeti güzel. Yok yok "çok güzel" ama tuz az olmuş. Birazda kırmızı biber çok olmuş gibi. Çok rondo ya da blender dan geçirmedim azıcık parçaları hissedeyim diye. Sonrakine daha bir rondolicem.

Tom'un hediyesi aynı yerde ;)


2012 Opel Corsa ile bir depo yolculuk

Önce 199,1 km idi.
Ağzına kadar doldurdum.
Sonradan 60 TL lik yakıt aldım (litresisi 3,96 TL den 15,15 litre mazot).
Gittim de gittim....
Tekrar ağzına kadar doldurduğum zaman kilometre 1445,8'i gösteriyordu.
Son dolumda 166,8 Liraya 42,12 litre mazot doldurmuştum(ilki gibi ağzına kadar).
Hız Sabitleyici (Cruise Control) kullanarak 70-80-90-100 km hızlarında gittim.
Ortalama yakıt tüketimi en son 4.9 litre idi 100 kilometrede(son 40-50 kilometrede çok boşa attım o vakte kadar 5,1 litre ortalama vardı).
Yolculuk esnasında anlık ortalama tüketim 4,5-6,5 aralığında seyir etmişti. Hız sabitleyici sayesinde yokuş yukarı giderken tüketimi arttırıyor(sabit hıza çıkmak için) yokuş aşağı giderken eğer sabitlenen hıza ulaşmak için gerekirse gaz veriyordu. Bu sayede benim o hıza ulaşmak için kontrolsüz gaz pedalına basışıma gerek kalmıyor ve gerekeni harcıyordu. Yokuş aşağı eğer gaz vermeden daha yüksek hızlara ulaşıyorsa sabitlenen hızda ilerlemek için motor freni yapıyor ama yakıt tüketimini 0(sıfır) gösteriyordu. Bu durumlarda peygamber vitesine(boşa) aldığımda ise 0,3-0,5 litre anlık tüketim gösteriyordu. Demek oluyor ki boşa almak yerine hız sabitleyici ile devam etmek daha az yakıt tüketimi sağlıyor.

Sonuç olarak; 1246 kilometre yolu 226 liraya yani 57,5 litre mazotla gitmişim.
Bu da kilometrede 0,18 lira, 0,046 litre tüketim demektir.
