Dunning–Kruger etkisi ya da Dunning–Kruger sendromu, Cornell Üniversitesinin iki psikologu Justin Kruger ve David Dunning’in tanımladığı bir algılamada yanlılık eğilimidir.

Cornell University’de görevli psikologlar Justin Kruger ve David Dunning’in tarihe geçmelerine ve 2000’de Nobel almalarına neden olan tanı, “Cahil cesareti” olarak tanımlanıyor. Teorileri özetle, “cehalet, gerçek bilginin aksine, bireyin kendine olan güvenini artırır” diyor.

Araştırmalar sonucunda şu bulgulara ulaşılmış:

Niteliksiz insanlar ne ölçüde niteliksiz olduklarını fark edemezler.
Niteliksiz insanlar, niteliklerini abartma eğilimindedir.
Niteliksiz insanlar, gerçekten nitelikli insanların niteliklerini görüp anlamaktan da acizdirler.
Nitelikleri, eğitimle artırılırsa, aynı niteliksiz insanlar, niteliksizliklerinin farkına varmaya başlarlar.

Cornell Üniversitesi’ndeki öğrenciler arasında bir test yapıldı ve klasik “Nasıl geçti?” sorusuna öğrencilerden yanıtlar istendi…

Soruların yüzde 10’una bile yanıt veremeyenlerin “kendilerine güvenleri” müthişti. Onların “testin yüzde 60’ına doğru yanıt verdiklerini” düşündükleri; hatta “iyi günlerinde olmalarıhalinde
yüzde 70 başarıya bile ulaşabileceklerine inandıkları” ortaya çıktı.

Soruların yüzde 90’ından fazlasını doğru yanıtlayan-lar ise “en alçakgönüllü” deneklerdi; soruların yüzde 70′ ine doğru yanıtverdiklerini düşünüyorlardı.

Tüm bu sonuçlar bir araya getirildi ve Dunning-Kruger Sendromu’nun metni yazıldı:

“İşinde çok iyi olduğuna” yürekten inanan ‘yetersiz’ kişi, kendini ve yaptıklarını övmekten, her işte öne çıkmaktan ve aslında yapamayacağı işlere talip olmaktan hiçbir rahatsızlık duymaz! Aksine her şeyin
hakkı olduğunu düşünür!

Ancak bu ‘cahillik ve haddini bilmeme’ karışımı mesleki açıdan müthiş bir itici güç oluşturur.

‘Eksiler’ kariyer açısından ‘artıya’ dönüşür.

Sonuçta, ‘kifayetsiz muhterisler’ her zaman ve her yerde daha hızlı yükselirler…

Bu arada, gerçekten bilgili ve yetenekli insanlar çalışma hayatında ‘fazla alçakgönüllü’ davranarak öne çıkmaz, yüksek görevlere kendiliklerinden talip olmaz, kıymetlerinin bilinmesini beklerler…Tabii beklerken kırılır, kendilerini daha da geriye çekerler… Muhtemelen üstleri tarafından da ‘ihtiras eksikliği’ ile suçlanırlar…”

Zimbra as a backup MX server
(Zimbra Community 5.0.8 & NE 4.5)
Had a hard time finding this info and finally found one post that correctly pointed in the right direct but didn’t actually detail all the info.
Backup MX: Have Zimbra accept mail on behalf of some other domain in the event the other domain is temporarily unavailable and forward to other domain when it becomes available.
Yes I know about dynamic dns providers offering backup facilities but I want my mail housed/processed by people I know and trust and not some other company. I also don’t want to pay extra to some other company when we have perfectly good facilities ourselves.
Postfix does this with the “relay_domains” functionality. Although Postfix is the MTA under the covers, I want a solution that will work with Zimbra’s configuratinon umbrella and not get smoked by an upgrade or system restart.
Server “thisdomain.com” wants to provide relay services for server “thatdomain.com”.
1. Add the domain to the server:
zmprov cd thatdomain.com zimbraAuthMech zimbra
2. Create full-domain forwarding to the intended destination:
zmprov md thatdomain.com zimbraMailCatchAllAddress @thatdomain.com
zmprov md thatdomain.com zimbraMailCatchAllForwardingAddress @thatdomain.com
zmprov md thatdomain.com zimbraMailTransport smtp:thatdomain.com
3. Have “thatdomain.com” mgnt add “thisdomain.com” as a higher number MX record to their DNS entry.

UPDATE

Install Plex Media Server on Debian

Install curl

sudo apt-get install curl -y

Now add source repositories, there are three separate lines here

sudo curl http://shell.ninthgate.se/packages/shell-ninthgate-se-keyring.key | sudo apt-key add –
echo “deb http://www.deb-multimedia.org wheezy main non-free” | sudo tee -a /etc/apt/sources.list.d/deb-multimedia.list
echo “deb http://shell.ninthgate.se/packages/debian wheezy main” | sudo tee -a /etc/apt/sources.list.d/plex.list

Make sure it runs

sudo apt-get update && sudo apt-get install deb-multimedia-keyring

Update and install the plex media server

sudo apt-get update && sudo apt-get install plexmediaserver -y

See if you can connect at http://ip.address:32400/manage/index.html

Plex media server will autoboot 🙂

If you are getting permission issues it is because Plex runs as its own user, you can change the user Plex Media Server runs as to fix the permission issues you get from CouchPotato, SickRage, Sonarr, Headphones and others.

sudo nano /etc/default/plexmediaserver

Find this line

PLEX_MEDIA_SERVER_USER = plex

Change plex to your regular user

PLEX_MEDIA_SERVER_USER = username

Ctrl+X, Y and Enter to save the configuration

Restart the Plex Media Server service

sudo service plexmediaserver restart

Configure Plex Media Server

Open up your Plex web interface at http://ip.address:32400/web

NOTE: Plex media server must be configured form localhost.
consider connecting over ssh proxy..

Because they need to check quota info before booting when the server node rebooted in an inproper way.

it takes ages to calculate quota and boot containers in big servers with lot’s of ram and lot’s of containers.

more info here:

http://forum.openvz.org/index.php?t=msg&goto=30102&

so basically

to fasten things up

if you are trying to boot your containers when you come back from a power failure:

vzquota off $VEID
vzctl start $VEID
vzquota on $VEID

yes I know, ploop is the answer, or is it?

I’m gonna check it later…
