more smaller icons in the windows 8 alt+tab / cool switch

by .pQd
recently i’ve moved from win7 to win8. i tend to have dozens of applications open and the default number of programs displayed after pressing alt+tab in win8 is too low. this registry change brings the win7-alike layout and adds more columns and rows: you might want to log off and log on for all the ...

openvpn point-to-point server listening both on v4 and v6

by .pQd
at work i have openvpn between OVH dedicated server and our datacenter. due to varying bandwidth we sometimes use udp over ipv6 and sometimes over ipv4 as an encapsulation method. whenever we did the switch we always had to reconfigure both ends of the tunnel. it turns out that with recent openvpns and kernels it’s ...

squid3 no longer working after upgrade to jessie

by .pQd
on one of the servers i’ve just upgraded to jessie i got my squid3 bricked. i could see the process in ps, yet it did not listen on tcp/3128: restarting it did not give anything interesting in /var/log/squid3/cache.log: after a while of clueless googling i thought – maybe there’s some problem with communication over loopback. ...

by .pQd
i’ve ‘convinced’ my samba running under debian wheezy/jessie to provide me access audit logs without being too verbose. here’s how.

by .pQd
i’ve done a routine upgrade of wordpress 4.1.x to 4.2 and later 4.2.1. all seemed fine until the day i wanted to manually adjust the menu structure using wp-admin > appearance > menus. each attempt of saving my menu resulted in it being wiped out completely

Taling Chan floating market, Bangkok hike

by .pQd
i stayed in Bangkok for 3 nights. i took one-day trip to Ayutthaya and have spent rest of the time hiking around. the longest hike i took was to Taling Chan floating market. as in many other cases it was more about the way there and back than the destination itself.

Ayutthaya

by .pQd
as in 2012 i’ve done a one-day trip to Ayutthaya. it was very much worth repeating and getting away from noisy Bangkok.

Chumphon, Hua Hin

by .pQd
on my way from Koh Tao to Bangkok i’ve stayed for one night at Chumphon and then Hua Hin. the first one was totally not-touristy, second – quite opposite; i’m glad that i decided not to rush towards Thailand’s capital and visited both.

hiking on Koh Tao

by .pQd
i took a ferry from Koh Samui to Koh Tao and stayed there for 2 nights. the island was quite touristy but still worth visiting. i looked at the map and thought to myself.. if there’s a route coming from the west and another one from the east – there surely must be some path ... Read More

hiking on Koh Samui

by .pQd
during my recent trip to Thailand i’ve spent 4 days at the Koh Samui island. i’ve stayed in the southern part – near Baan Hua Thanon – fisherman village with quite obvious Muslim influence. the choice was great – area was not very touristy and a great starting point for hikes.

BLKDE3815TYKH0E headaches

by .pQd
we’re setting up a small computer that will act as vpn end-point. we decided to try something smaller this time – BLKDE3815TYKH0E. as it turned out it’s not as well polished as one would expect from intel. my colleagues had to pull out debian wheezy usb pend-rive with the installer to be able to finish ...

xwiki, html macro tag and unwanted javascript

by .pQd
xwiki – by default – allows contributors to embed arbitrary html, including javascript. it does not take much effort to include something like: then you just need to lure your victim into visiting given wiki page while being logged – you’ll get a http request containing that person’s cookie that can be re-used to impersonate ...

bridge on vlans on active-backup bonding under debian

by .pQd
the idea: i’d like to run kvm/lxc on debian, have guests bridged to couple of vlans and handle the network failover on the host level. network failure should be detected using arp probes not just the link [ mii ] status. after few attempts i got it working in the test environment.
