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.
as in 2012 i’ve done a one-day trip to Ayutthaya. it was very much worth repeating and getting away from noisy Bangkok.
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.
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 …
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.
while visiting Hong Kong this winter my colleague and ex-flatmate from Goteborg times took me to the Kowloon Byewash Reservoir / Golden Hill Country Park.
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.
i’ve received for testing a new dell r630. before buying few of those i wanted to make sure that debian wheezy has kernel including all the needed drivers. it seems that it has.
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 …
i’ve sepnt two August/September weeks traveling with my parents from Dubrovnik via Sarajevo and Zagreb to Budapest. short brain-dump with hiking maps follows.
at work we rent a dedicated server from OVH; except unexplained openvpn throttling all is working pretty well for the price we pay. besides primary IPv4 address OVH can provide few additional ‘failover’ IPv4 addresses and /64 IPv6 subnet. in our setup some of IPv4s and IPv6s are routed to a KVM VM. below – …
i’ve bought 2x Dell PowerEdge t20 – they’ll serve as HA pair of routers/vpn endpoints/file servers for a new office. it was the first time i played with intel amt. it’s not bad but neither perfect.
i’ve spent 2 weeks at the beginning of March at Gran Canaria. below – list of the more interesting walking trails we’ve taken.
a while ago i helped a colleague with moving away from mysql-based text search based on MATCH .. AGAINST to sphinxsearch to improve the performance. without much surprise this helped a lot to improve the response time. recently i was asked to take a look at the setup again and see if we can do …
some walking trails i’ve taken during my last trip to Hong Kong, Macau, Singapore, Malaysia.
i’m backing up in total ~90GB of mysqldumps each night. the more data, the bigger pain it is.
a brain-dump from my recent trip to Hungary, Slovakia, Austria and Czech Republic.
at work we’ll soon make use of dns-based geo load balancing to have users in americas / asia ‘talk’ with north am site and rest of the world – with the european site. we preferred to avoid modifying the client application so the dns based solution seemed reasonable. below – quick overview of the setup …
while rescuing data from server having problems with either disk or raid controller i had to clone data from 2x 1TB RAID1 to 4x 500GB RAID10. as it turned out the space available on the destination server was 1GB less than on the source machine. shrinking the source drive with gparted-live and dd’ing over the …
below – a description of somewhat convoluted backup system that so far have been serving me pretty well.
