Safety fail



Apparently only the hosts need safety screens

Dear Steve Conroy,



You can’t be serious.




You wants to filter all Internet connections now, without the option of opting out?! You want every Australian to be on a list so you can see who is “naughty” and who isn’t?!




You can’t be serious.




You wants to filter all illegal material on the Internet?!




You can’t be serious.




How on earth do you propose to classify the contents of more than 181,000,000 websites (Sept. 2008, Netcraft)!? Assuming a government worker can classify a site as illegal or legal in 1 minute, that person will have to work non-stop every day for 344 years to classify 181,000,000 websites.




You can’t be serious.




How on earth do you propose to even filter that many sites without rendering the Internet useless?!  




You can’t be serious.




How can we be sure the site blocked really is illegal, when we can’t access it!? How do you stop the system from abused? How do you correct the system’s mistakes? Why isn’t any of these described in detail?!




You can’t be serious.




How on earth are you planning on preventing people from circumventing your flitters using encryption?!



You can’t be serious.




Get a fucking clue Steve Conroy. The Internet doesn’t work like that. You have a background in the broadcast industry, and the Internet is nothing like it. You should leave technical decisions to people who know what they are talking about and stop pissing off every Internet literate Australian.






DIAF,

For shame Dr Hearnden

"...Why should small business take a hit for a public health measure?" -- Dr Hearnden


I am amazed a doctor of all people would utter such capitalistic remark.How can a doctor question whether or not it is in the business' interest to improve public health?



Businesses derive their income from the public, and a healthy public is more capable of providing income to businesses. The only businesses which benefit from an ailing public are medical clinics. This leads to me to think Dr Hearnden belongs to a special class of doctors who prefers to make money from treatments rather than from cures. In other words, putting profit before his patients.

Some people are going to hate me for this

But you can get the current function's name by using:



sys._getframe().f_code.co_name


Seems to work alright for debugging purposes. See the link embedded in the title for the origins and 3 other methods.

Electronics, it gets the heart pumping



There is it, the new current limited H-bridge for my team's SUMO entry. Put it together this afternoon, and will be mounted on a piece of perspex (which I forgot to bring home) and then mounted on the robot.



Statistics:


  • Numbered of times chickened out of short circuit test: 4

  • BPM while testing: 100 (estimate)

  • Short circuit current: 8A



This is basically 2 MOSFET H-bridge each powered by a LM138/LM338K rigged with 150/150K for R1 and R2 respectively, providing ~13.5V.



Cheers,

Steve
