The media wasn't helping either, with their constantly showing Zimmerman in prison garb, while showing a 12 year old Martin (to the point where a lot of people actually thought Martin was 12 years old).

Since trials take so long to happen, when it does the jury has already been widely influenced by the media, specially in high profile cases like this. Even in Brazil we read about Treyvor Martin's killing. It goes to show the huge power the media has on cases like this. I am willing to bet most of the jury already had their mind made even before the trials began.

I remember Borland Delphi , almost identical to Visual Basic
that was pretty easy to learn and start making windows applications.


Do you think that exposure to BASIC can mutilate your mind? haha

Delphi is pretty easy to learn,and extremely powerful. I started with Delphi with version 1.0, I guess around 1995. When Delphi 4 came out, I got certified from Borland and I've been making my living with Delphi since then.

I went through all the changes Borland had, the first being renamed to Inprise and nowadays it is called Embarcadero, with is a pretty idiotic name.

I really, REALLY love Delphi.

This made me remind of the fictional, humorous C+- (C More or Less)  language that appeared on UseNet a few decades ago.


 I can't find the full complete text of the C+- joke in the web (I have it at home), but the above is complete enough.  The complete "reference to C+-"  includes keywords such as EvenIf

After watching the CAPCHA video, I was left with one major question.. How does the computer know that the capcha that your translating from a book is translated correctly? I guess next time I read a book online and see a word that clearly doesn't fit I can blame some dyslexic kid trying to sign up for yahoo!  smiley-lol

The "HCR" (human character recognition!) is not done based on just one identification/recognition. The same word is sent to several reCAPCHAs, and the word more recognized is the one accepted as the correct one. This way, even if one kid is retarded, his recognition of that word won't count.

I saw this on Atmel's Facebook page and immediatly thought about this thread:

Arduino-powered Nerf Vulcan sentry gun automatically aims and fires at targets

As to why gun shop owners and the police don't cause problems I can make two suggestions;
  • Do they have direct access to the weapons after they leave work
  • What percentage of the population are they and what percentage of the problem do they cause

A) In most countries, law enforcement agents (LEA, for short) DO have access to weapons when they are off duty.

B) That is irrelevant. A "LEA" going in a gun rage is such an absurd thing that, when it happens, it makes first page in every newspaper in the world. So, when it happens, we know about it. The answer, therefore, is that it doesn't really happen that often. It is a lot more common for drug addicts and the regular, run-of-the-mill bad guy to go in a gun rage than a LEA.

I also agree that guns itself aren't the problem. Bad character and mental disorders are, for over 90% of gun-related homicide.

To do it without software, you can use a RTC like Maxim's DS1337+ . Basically, you program the DS1337+ to generate an interrupt at a given interval or specified time, which would be the RESET signal (actually it will need a transistor to bring RST low when the interrupt happens)

I find this to be a much better approach to WDT, although it is a bit more complex hardware-wise. The reasons is: if you depend entirely on software and the software fails, the Arduino won't reset.

When I see some medical x-rays and some ultra-sound images, I know absolutely nothing that is going on. Ok, x-rays are easier, but ultra-sound is just for the very trained eye. Even more modern image diagnostics methods, that give you clear near-photographic quality images, still require lots of training to understand and know what is going on with that patient.

The same goes for engineering (all types) schematics. Even some Fritzing drawings still require you to know before hand how a LED works, what are the GND and PWR pins on a 595, and so on. So, all one needs is training and some background information.

DO you have another arduino or a ICSP programmer ?

If you do, you can always reflash the bootloader, if you suspect it is misbehaving.

You are not reading a new value for the switchState variable from within the loop, so it will never break out of it.

What if the transistor was never developed?

What field of work / hobby would be your next choice be?...   (This would leave all things mechanical open along with electricity, incan bulbs, relays, Generators etc etc)

Knock on wood, man! Thank God we have the transistor. I can't think of any invention that changed the world so much as the transistor.

Most of my other hobbies do not require electronic devices: playing guitar (both electrical and acoustic) and harmonica, shooting  and photography. Granted, I use a DSLR, but I could just as well be using a mechanical analog camera (like I did when I was a kid).

As for profession, I probably would've become a psychologist, photographer or secret agent.

Jokes aside. Modern gunnery training takes an awful lot of ammo.  As far as I remember, I've heard something like 8,000 rounds per soldier mentioned if you want to have CB proficiency.

That is true, and the 8K rounds to become a good shooter is still a very conservative and optimistic estimate.

Remember that automatic guns go through a full 30-round magazine in a matter of seconds.

When I was an active IPSC shooter (IPSC is a shooting sport), on the 2 weeks before any major championship, I'd shoot 2K rounds per weekend, and that's just for practice. In the 2004 Brazilian National IPSC Championship, I finished in 3rd place in my class, and practice + competition consumed about 5,000 rounds. A master IPSC shooter can go through 10K~12K rounds a month EASILY.

10K rounds for one that practices shooting as a sport is not really that much. For taking one man without any  shooting experience and make that man combat-ready and a "good enough" shooter, I'd say 10K rnds is not that much.

It has to play Crysis and the IDE has to be backwards compatible to the ENIAC.
