Taling Chan floating market, Bangkok hike
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
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
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
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
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.

i have esxi 5.5 running on top of dell r620. since few months server has raid1 based on 2x intel s3500 800GB drives. but vmware [or maybe rather the raid controller – dell’s h710p] has seen it as a non-ssd drive: i’ve found a solution here and here: log in to the vmware server via ... Read More
BLKDE3815TYKH0E headaches
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
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
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.

lxc under debian: flood of “init: Id “4” respawning too fast: disabled for 5 minutes” in the syslog and large /var/log/wtmp
docker seems to be the new fad… which i don’t use at all; but i’m quite happy with lxc and have it deployed in the production on couple of servers.
UNION instead of OR in MySQL
i have MySQL that is run on arrays of increasing size: i remembered that the query optimizer will not be able to use existing indices for lastModified columns but.. the query execution time was acceptable, so i did not bother. recently much more data was added and query above, repeated quite often, caused a lot ...
