I notice that pdf http://www.blockyourid.com/~gbpprorg/mil/gps4/Wen_Spoof.pdf has been removed! I wonder if its because of attention from this community! Anyone got a copy?

Here is one for the UK http://www.onlineconversion.com/downloads/uk_frequency_allocations_chart.pdf

If you measure between pin 7 and pin 14 of your timer chip with a voltmeter(eg.multimeter) you will find the,,er... voltage. this much is self evident. The circuit shown will safely translate any of your quoted voltages to the RPi's 3v3 logic. As it is an inverting level shifter the logic will be inverted which is easily delt with in your software. The transistor can be any general purpose NPN signal transistor eg. BC107, BC108, 109,,,,,BC549C....etc.

I would have thought your "school" (-sounds funny to a Brit,- unless you are under 16!) is much less likely to block some other ports than 22 (after all that is practically saying its ok to tunnel out using ssh). I am thinking explicitly of ports such as 443 which is the standard SSL/HTTPS port, -if they block that then no secure sites will work such as banking or library sites so thats highly unlikely. If you are running a pure ssh server rather than say OpenVPN which also uses SSL then that should be fine. You will probably still get a few bots knocking on that port but they will not be expecting SSH there! There is also always port 80 of course, providing you are not running a web server on your (Home?) server. Also have you checked that they are not using a proxy which is more common in large institutions. You can find out the details of the proxy simply by checking the internet connection settings on the browser on one of the institutions machines and use those details in putty to get out that way (I do that all the time to tunnel out of my "institution" -and no I am not being held at her majesties pleasure!)

I was not making any value-judgement regarding the efficiency of the language, just pointing out that non-standard English can be excused when there is a rationale for it such as brevity in text-speak. But where there is no justification there is...well no justification.

I am pleased but amazed to find a discussion on the propriety of language brought up here. I have been tempted several times to comment along similar lines, but held myself back thinking I must be getting old or being overly didactic. However, as you say, self-consistent abbreviation is fine but, for example on this very forum two different people have typed "know"(sic) when they meant NO! I can understand the other way around but this is just perverse! I wont bit.ly and shame them even if I could be bothered. Such faux pas are where I draw the line as they are obviously contra to brevity (as they are often longer than the correct original), are not cultural references such as the ubiquitous but so last millennium teh (the) etc. Nor are they flowery historical vestiges (English, French and other "romance" languages are not the only ones prone to this) N.B. "R U COMN OVR!" -does not violate any of these criteria.. provided its in the right context ie if he was (not wos) texting you and exasperated with you. All languages be they linguistic or computer programming in nature are just one set of peoples codification of information (which is why its pointless to pick a best programming or linguistic language to learn – its the principals that are important) and like any “Formal System” it is important to obey the semiotic and semantic rules of that system for the full meaning of that information to be conveyed. Confusion arises when mistakes from miscomprehension (know & no) or rules from one system are applied to a different system, -context! Which is why it would be wrong of me to type this in txt spk...or con-txt. -Aphorism of the day.

Sorry, wrong forum.

I assume you have changed the external port from the SSH standard of 22 to something high and random. If you are using 22 you will get the world of bots cherry knocking, I find it amazing how simply changing the port now and again reduces this to virtually nothing.

If it truly is just a straight wire with no coils on either end (top or bottom loaded) then it is a simple quarter or half wave monopole. So for a custom job make your own out of a 30mm(1/4wave) or 60mm(1/2 wave) piece of solid copper wire soldered to the central contact of an SMA connector. Just seen wiki has a decent article http://en.wikipedia.org/wiki/Monopole_antenna As its so low power impedance matching which is the hard part in designing antennae is less of an issue.

I just wondered if anyone here has had a go at GCHQs recruiting "Crack the code challange" http://www.canyoucrackit.co.uk/ ?

You might be thinking of FreeCap I use a portable version on my windows USB drive partition to launch other portable progs such as Filezilla or thunderbird so that they use the socks proxy of either an SSH or SSL tunnel I have established from the thumb drive. That plus gateway and proxy discovering tools have enabled me to tunnel any programs that dont use mutiple simmultaneous ports (such as old Netmeeting or unmodified skype)out of the most restrictive of environments.

Quote: "from what I have seen with many tutorials and insanely overpriced ones is that they all followed a model where everything was not electrically conductive with each other" I think its OK that the director and reflector elements are connected as at the characteristic frequency the connections are at node points, the crucial thing is that the driven element (the folded dipole) is insulated from the rest.

Just watched Hacktip on WiFI channels. I am stoked because when I fist saw the piece on the Ubertooth I thought how fantastic at last a cheap quasi-USRP device! I wonder how easy it would be to make a narrow spectrum-analyser... and now I find the work has been done for me. Now before I buy one could someone give me some details on the front end of this device. specifically I want to be able to monitor interference in our COFDM video link channels between 2.06 GHz and 2.3GHz but at these frequencies I doubt it will be as simple as changing a crystal.

That would be ironic indeed as the guys behind the ARM processor built the BBC micro! -Did you see "Micro Men"?

What you want is a Dovado UMR. I have a couple of these, one for my parents place in Italy (ilcollegio.com) to give them internet in a fairly remote rural part of italy. I can turn their server on from here in the UK and sort out any issues they may have remotly. Also have one in my Car as part of my discreet CarPC as it can also hook into the GPS Rx it logs all my journeys and as its so well hidden, if my car ever got stolen I could track it online (toyed with the idea of remote immobilization but think its superfluous. :) )

What you want is a "Darlington array" chip such as the ULN2003 I think that data sheet will make it pretty clear how to wire it up.

Thanks Sparda, I knew this was the place to come for a reasonable answer (I suspected there was no universal solution *sigh*)

Don't worry, AI as the lay-person thinks of it is not possible ie a purely digital mechanism cannot become conscious. Ref: Roger Penrose's "The Emperors new mind"

I have asked this on the ubuntu forums but no one has touched it with a barge-pole. I am beginning to suspect its the Linux Achilles heel or the question no one wants to mention, like a demented relative locked-up in the basement anyway here what I put: I have been using ubuntu for about 4 months now and I am loving the power! One thing is really frustrating me though and I'm sure I'm not the only one with the problem(I have seen simmilar posts but no really satis answer. The scenario is this: as an (ex?) Windows user I have built up a uniform and hierarchical storage structure on my home server and/or NAS, with media mapped to one drive and docs and files on another. This works fantastically for the windows network as all references and links are consistent. eg. for playlists the entries are the mapped media drive so even though the mp3s actually live on my external USB drive (comming up as say drive E:) a script maps the media folder to M: on any of my systems or any of my storage media so the paths are always correct. Also in my projects subfolders I have shortcuts to other relevant project folders or documents so I dont have to duplicate anything. Now with Linux I can still map windows shares after mounting them, I will just have to re-do the playlist etc entries (grep will help). but the deal breaker is that symlinks are not supported across the network, unlike plain old windows shortcuts and there is no unix equivalent! The closest I have come as an alternative is dropping nautilus script files which opens an instance at the location referred to, inelegant or what!?! I am also working on a script which is added to the right click which will extract the location info from the windows .LNK shortcuts and open nautilus there but I am sure I must be missing something obvious for such a critical function... help! (sorry for the long post but I wanted to be clear).

Most chip cameras are infrared sensitive and have an IR blocking filter so they are not overloaded,. Its usually quite straight forward to remove it (warranty=void) and replace it with black exposed film to create an visible blocking, IR pass filter, and Fanny's your aunt! you have an IR camera. B)

I use Satellite IP connections regularly in my job. - VSAT for radio contributions and BGAN modems for cheapo TV two-ways and I must admit I have not given much thought to security -you have got me thinking, -though I would have thought a "man-in-the-middle" attack would be difficult on a Satellite uplink!

I dont think you have to use their compiler maybe xduino.com will work or gnuarm.com. Good point though I will ask before ordering. As I say sorry I havent gone into it that far yet cause I need at least 24 hours that I know will be uninterrupted before I even think of devoting much time to such projects. (The only reason I can browse the internet and lurk forums is I have legitimate stretches of dead time waiting for the next frenetic period of panic followed by another bout of boredom).

We had a contributor yesterday who kept referring to "David Clegg"... Feels like we've elected Jedwood.

Has anyone else looked into the mbed dev board?? B) Looking at its specs there is little it would not be able to do. - the most pertinent points from a RuDu point of view are: 1. Fast 2. Has on board Flash mem so you could more convincingly disguise it as an "innocent" UFD (already appears as a UFD when you plug it in) 3. Has on board Flash mem so you can store all your acquired data. 4. Has ready built in ports for most things including Ethernet (ultimatly combined with a small wifi module,- just think!..mmm...control from the master computer.... though it might be so big now you have to dress it up as a 2.5 usb harddrive) 5. It already has a big blue LED built in! - Of course this depends on the code to make it appear as a HID, something on the lines of This Project. I could go on but the point is, with work being so manic lately, covering the politics and volcanic ash, I wont have time to do much development myself so at least here is a heads up for a very promising device. [ed] I see reading other posts other people are already looking into wifi but I think lack of teensy cpu power will quickly become an issue.

Sage words as ever Vako (and I do work in TV ) and conversely the broadcasters take the potential of IPTV seriously, thats why so much has been invested in iPlayer and eventually Project Canvas so you can see its exciting times to be a self-starter in independent Media, and I respect Darren for actioning what I only thought about for years!
