Wifi security playing
I was reading about wifi cracking techniques for some time, and even trying to use it with my previous laptop, but without any success (wifi card compatibility issues). Finally, i stumbled upon an article on lifehacker explaining wep cracking with backtrack linux distro. Nice thing in article is that they specified exactly wifi card model, which can be purchased on ebay for 30$. So card finally arrived few days ago:) Backtrack ISO is currently downloading, Virtualbox on laptop is ready, just need to follow one of many guides that can be found on google! Neighbors will not be happy with my new experimentation:) Just to be clear, as with any hacker/cracker out there (I hope), I’m not planning to do any damage, still personal info, I just want to connect to some other wifi and use it a little bit for mail checking, surfing, etc. When there’s no 3G mobile signal, you don’t have any choice IMO, and there’s always some wifi in range, with WEP protection…
“God wanted you to put your data inside Azure Table Storage”
- That’s how did Jerislav described importance and benefits of new Azure Table Storage. Very nice presentation on Advanced Technology Day 6. Talking about table (nosql) vs relational (sql) storage, I think i’m slowly shifting from sql databases. Constant pain of normalizing data, writing crazy (left outer, …) joins, and keeping all organized and in good shape is driving me crazy. Table, document data storage fits more natural in lot of projects I’m doing. Have to try it soon. Well, this is new to me. After actively using Silverlight 4 and writing IValueConverter classes for implementation of StringFormat inside binding, it seems that it already exists. Not just that, it can be combined with culture information. Nice.
Very simple validation
Few days ago I needed to implement some business rules to Silverlight application that I’m building for my friend, so I coded this simple rules engine. The goal is to have objects that does some validation, and some easy way to find them, so I don’t need to register every rule when I write one. Interface that every rule implements looks like this:
To find all rules in application I used this simple combination of Linq query and reflections:
For triggering validation, method ValidateParts() must be called. As you can see, rules are cached inside static list, so there’s no need to iterate all classes inside running assembly every time validation is called. Don’t know how much speed does it gain, but at least it makes me happy :)
twitter integration
tumblr post for my twitter integration. I’m interested how many folks from my twitter timeline are also present on tumblr? I see here “follow” link, but not quite understand how it works. And as i write this on my iphone, i’m getting really pissed with official tumblr app because it doesn’t support screen rotation so this typing is pain for hand and fingers. This is also my last day in Split, for which i must say is nice city with worst traffic i’ve seen lately. Visited FESB and Linux vs Win fightclub, but didnt find any hifi store.
Hello World to tumblr
It’s time to try this strange new service called tumblr. Maybe it’ll force me to write more often, because I neglected old-school blog (Hudos Vibe) for which I’m not happy. In my evergoing quest for service where I can write about things that occupies my every day life (from everyday boring stuff to brainac programming development something), let’s give tumblr a try! Let the show begin … |
