below – a description of somewhat convoluted backup system that so far have been serving me pretty well.
in branch offices i tend to install two identical pcs running linux and working in active – hot-spare setup. things evolved over time – one location has both routers running under vmware esxi on two different hosts, another – hardware raid, other – desktop-class pcs with single hard drives. hardware raids are good as long ...

wd [and other vendors] sell green drives; they are reasonably cheap but have annoying tendency to spin down very very quickly. i bought recently 2x WD20NPVT-00Z2TT0 with intention of using them [in very unprofessional fashion] in PERC6 RAID1 array.
i got another chance to visit Asia. instead of suffering cold, dark and cold January in Sweden i’ve spent 3 weeks in mild Hong Kong & Macau, tropically hot Singapore and pleasantly warm Vietnam.
few days ago, after 19 weeks of waiting, i have finally received my raspberry pi.
… that did not drive me crazy so far.
i’ve been thinking about working remotely for a few weeks from some warm[er] country for quite some time. finally i’ve tried – i’ve spent 3+weeks in Portugal while taking just 2 days of holidays. all went surprisingly well.
so i’ve hit the road again – packed my trusted 8-10yo travel bag, took laptop, camera + 3 lenses, kindle with 400+documents waiting to be read or deleted, mp3 player, gps, two mobile phones, earplugs, some old clothes and nothing more. i’ve even left intentionally at home travel guides borrowed from the local library – ...

we’ve been poking around ossec for a while. it’s nice and all but… i never liked the idea of opening additional ports on the production server or letting it ‘call home’ with alerts to the central monitoring machine. i prefer ‘polling’ model where central server communicates with monitoring nodes. ideally all should be done via ...

this post inspired me to check how much performance can we gain by just upgrading to more recent kernel on the internet-facing proxy servers at work.
for the last 10 days of my Asian adventure i was traveled around Philippines.
from Singapore i flew to Bangkok Thailand and stayed there for 5 days.
after 10 days in Hong Kong my next stop was Singapore. i had 2.5days to use for some meetings and sightseeing.
i’ve spent last month in Asia – Hong Kong, Singapore, Thailand and Philippines. totally new experience in many ways.
by a coincidence [process well described in this xkcd’s comics] i’ve stumbled on the definition of Benford’s law. since i have access to quite a lot of different economic & financial data i’ve decided to check if that law applies also to it.
in search for some February sunshine i’ve spent 11 days in Morocco.

while sopa/pipa legislation in the US seems to be postponed after a wave of protests acta in EU/Poland is doing just fine; acta possibly will be ratified [at least in Poland] without much of the mainstream attention. is pushing this law through the EU parliament going to be the only ‘success’ of otherwise pathetic polish ...

i’ve been planning for a while to move away from apache2 as a reverse proxy in front of java appservs and start using nginx. i had two reasons: nginx can handle much better large number of concurrent connections [something we can make use of if we start using long-poll/comet], nginx gives more control over buffering ...

for the last few days i’ve been looking into java7… it surely seems faster. but also some of my old code broke when run under it.
