  1. 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?
  2. Here is one for the UK http://www.onlineconversion.com/downloads/uk_frequency_allocations_chart.pdf
  3. 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.
  4. 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!)
  5. 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.
  6. 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.
  7. Sorry, wrong forum.
  8. 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.
  9. 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.
  10. I just wondered if anyone here has had a go at GCHQs recruiting "Crack the code challange" http://www.canyoucrackit.co.uk/ ?
  11. 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.
  12. 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.
  13. 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.
  14. That would be ironic indeed as the guys behind the ARM processor built the BBC micro! -Did you see "Micro Men"?
  15. 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. :) )
