jibble paul mutton jibble homepage of paul mutton most software on this site is available under the gnu general public license gpl since the gpl may be too restrictive for use in proprietary applications a commercial license is also provided high severity a security blog if you re interested in online security penetration testing hacking and so on you may be interested in my new blog high severity i ll be kicking things off by interviewing a member of anonymous so stay tuned to highseverity com and let me know if there are any other features you would like to see on the site 7 jan 2011 16 58 47 pst permanent link cyber security challenge uk cipher challenge winner yay i just won the cyber security challenge uk cipher challenge rather appropriately i ve won season tickets for bletchley park plus a personal tour of the refurbished colossus code breaking computer from world war 2 this is how i cracked the code 30 jul 2010 1 48 46 pdt permanent link o2 wireless box iii still insecure after waiting several months for o2 to fix the wireless router vulnerability i reported last year i was about to discuss how the vulnerability worked but then i discovered in less than one minute that their fix contains a new vulnerability which makes it possible to do csrf attacks that means an attacker could steal your wep wpa2 key change your password set up port forwarding etc read more here 10 apr 2010 8 46 00 pdt permanent link o2 broadband router security a few weeks ago i discovered a serious security flaw that affects hundreds of thousands of broadband internet users i made several attempts to report this problem to o2 but they erroneously insisted that the security of their wireless boxes exceeds industry standards and is acceptable for home use i strongly disagree so i have published my findings to try and get them to take the matter seriously it s quite an interesting attack vector so i shall describe it in full detail after they have fixed the problem 28 aug 2009 12 14 35 pdt permanent link current cost graphs i ve been jibbling about with a current cost device lately and have been working out how to get data out of it and into some shiny graphs what with the current trend of rising energy costs this is both enlightening and depressing 8 sep 2008 13 23 05 pdt permanent link bbc iplayer drm hack bbc iplayer has been available for a while now but there have been a few things i still don t like about it the iplayer client started off as a windows only application that rather covertly stole lots of your bandwidth by installing a peer to peer network client which remained running even when you weren t using iplayer crappy digital rights management meant that you could only watch downloaded programmes for a certain amount of time and even then things would tend to break and you would have to download everything again in order to watch it after a while they started to let you stream programmes directly from their website without needing to install this junk but the quality was not as good fortunately a few days ago the bbc made iplayer available to iphone users the video quality is much nicer and it doesn t contain any of that wanky drm bollocks the bbc iplayer website currently determines whether you re using an iphone by looking at the user agent header that the web browser sends to the server each time it makes an http request so using firefox and chris pederick s user agent switcher it is possible to trick the bbc iplayer site into thinking that you re using an iphone thus giving you access to the better quality drm free downloads spoofing the iphone set your browser s user agent to something that looks like an iphone mozilla 5 0 iphone u cpu like mac os x en applewebkit 420 khtml like gecko version 3 0 mobile 1a543a safari 419 3 now have a look around the bbc iplayer website and find your favourite episode of eastenders the next bit is slightly awkward firefox will want to open the video within the browser using something horrible like apple quicktime but all we want to do is download the video so we can keep it forever remember its drm free i made the following piece of javascript which will create a new web page that contains a direct download link for the video simply redirecting to the video url makes the browser try to play it so you ll need to right click on the url and use save as the default filename will have a htm extension so rename the whole file to something meaningful and give it a mp4 extension instead downloading the drm free video the easy way to make it easier to use the javascript you can save it as a bookmark and keep it to hand on firefox s bookmarks toolbar this is the code you ll need to bookmark all on one line javascript window location data text html p download the video with a href document getelementbyid mip flash player getelementsbytagname object 0 firstchild value this link a right click save as rename with mp4 extension p so now it s trivial to get hold of drm free content from bbc iplayer install user agent switcher add a new user agent string to firefox so you can pretend to be an iphone go to the iplayer site with your iphoney browser and find something worth watching hint eastenders click on the special javascript bookmark shown above right click on the link it gives you and save it somewhere giving the file an mp4 extension finally play the video as often as you like using vlc 12 mar 2008 13 04 17 pdt permanent link pircbot 1 4 6 irc library released it s becoming increasingly common for irc networks to require clients to register with nickserv and then identify themselves to nickserv each time they connect failure to do so prevents the client or bot from being able to send private messages to other users and the server may even force a nick change upon the client the new release of pircbot 1 4 6 addresses this problem by allowing bots to identify with nickserv using a previously registered nick and password this works on irc networks which support raw nickserv commands such as freenode 11 apr 2007 11 49 13 pdt permanent link lens hoods one of my latest web sites which offers free downloadable lens hoods is mentioned in a bbc news article the site lets you download lens hoods for a variety of slr camera lenses which can then be printed onto paper or card and glued together to make an impromptu lens hood lens hoods are an essential accessory for any photographer as they prevent stray light entering the lens and reducing image contrast so if you re into photography and haven t got a lens hood yet why don t you go and grab a free one from www lenshoods co uk 29 may 2006 12 44 21 bst permanent link mobile googlebot uses nokia 6820 someone recently commented on a large proportion of their web site visitors coming from nokia 6820 devices even more than from mozilla based browsers taking a quick peek at my own apache log file i noticed quite a lot of requests coming from a range of ip addresses owned by google with the useragent set to nokia6820 2 0 4 83 profile midp 1 0 configuration cldc 1 0 compatible googlebot mobile 2 1 http www google com bot html this probably explains these erroneous stats obviously google are not really using nokia 6820s to crawl the web but they are presumably performing separate crawls with this different user agent to see whether sites return different content if they know the client is using a phone or other small screened device it would be interesting to know how many sites do actually return different content for mobile browsers 28 apr 2006 13 24 12 bst permanent link time to go after several years of being heavily involved with computers and the internet i ve decided to give it all up and go and live in a shanty town in peru here i will enjoy an exclusive plot in a pueblos jóvenes with no electricity supply and no nearby telecommunications masts it s possible that you may be able to contact me with voip voice over intelligent pigeons but due to a local outbreak of h5n1 bird flu this cannot be guaranteed obviously i will not be able to update this web site after i have embarked upon my new life if you would like to buy it offers may be passed on to my solicitor mr uve binadd 1 apr 2006 7 37 25 bst permanent link kitecam ii donate your camera it s been quite a while since the original kitecam adventure saw my 300 digital camera soaring into the skies to take aerial photos of the university of kent unfortunately it went a bit wrong and the camera ended up getting completely trashed when it hit the ground just a little bit too hard it was a bit of a devastating moment what with me being a poor student and having broken my only camera but still it seemed like a good idea at the time now i believe it is time to relive this fun experiment by planning kitecam ii my initial thoughts were to avoid the same mistakes as last time by putting a bit more effort into making sure everything is well organized and safe but then i suddenly realised there is no fun without danger so i m going to do kitecam ii in pretty much the same way it will involve a kite a stupid impractically huge kite it will involve bubble wrap oh yes it will involve lots of string and some toilet roll it will involve some ingenious remote shutter mechanism which can be attached to the camera but most of all it will involve that ludicrous element of danger that makes it so fun this has made me realise that it s best to use someone else s camera for this kind of thing if you would like to donate a 35mm slr camera and lens to be used in kitecam ii please contact me wide angle lenses would be best for this kind of stunt film cameras will do fine but i certainly won t turn down a chance to send someone else s digital slr in the air please note that any cameras and lenses you donate will not be returned they will most likely end up in pieces however you will be safe in the knowledge that you ll be helping out with a fun project and your donation will be mentioned on the inevitable web page of photos that will appear after it s all done so what are you waiting for let me know if you have any of the following that you d like to donate 35mm film or digital slr camera wide angle lens for 35mm camera crazy ideas to make kitecam ii more exciting i look forward to hearing from you 5 mar 2006 22 30 21 gmt permanent link autoboxing considered harmful i was not a great fan of java 1 5 when its new features were announced sure i could see the benefits of things like autoboxing but having taught this stuff to university students for 3 years i couldn t help but think of the problems it could cause i came up with the following example which demonstrates autoboxing in action note never write code like this integer a1 100 integer a2 100 system out println a1 a2 prints true note that this code will not compile in java 1 4 or earlier as you cannot assign an int to an integer without autoboxing the equality operation could appear to return true because the int values inside the integers are the same but it s actually because when a1 and a2 are assigned they end up pointing to the same immutable integer object testing the same object for equality with itself obviously returns true this alone can cause some confusion as changing the code to do things the old way would give different results integer a1 new integer 100 integer a2 new integer 100 system out println a1 a2 prints false to most people the above difference would be obvious a1 and a2 both point to different integer objects they just happen to contain the same int value so the equality operation returns false now let s jump back to that first example where two autoboxed integers are compared what happens if we change their values from 100 to 150 integer b1 150 integer b2 150 system out println b1 b2 prints false most people look at this and go huh why does it return false now unfortunately only values between 128 and 127 are assigned to the same immutable integer object in a pool of integers anything outside that range appears to be assigned to a new integer object so equality will never happen using autoboxing in this way is a poor practice but i can imagine it being all too easy for student programmers to fall into this trap and end up getting really confused i even know people who work with java every day and were very surprised by this sun s advice on when to use autoboxing and unboxing is pretty sound and should be observed and taught in order to prevent any weirdness happening use them only when there is an impedance mismatch between reference types and primitives for example when you have to put numerical values into a collection it is not appropriate to use autoboxing and unboxing for scientific computing or other performance sensitive numerical code an integer is not a substitute for an int autoboxing and unboxing blur the distinction between primitive types and reference types but they do not eliminate it wise words indeed 21 dec 2005 20 59 06 gmt permanent link search this site copyright paul mutton 2001 2013 http www jibble org feedback welcomed main www jibble org contact me my
