deutronium··on Show HN: Handicareers.com – A simple job board for disabled people
This sounds like a cool idea, good luck!

Am I right in thinking there's no jobs on there at the moment though, I couldn't seem to see any.

Edit: Getting a DB error now, but could see the page before

deutronium··on How to save multiple numbers into one byte
Yeah that's a good point! Don't know why I didn't think about that.
deutronium··on How to save multiple numbers into one byte
Neat :)

I wrote some very slow code to set/get the Nth bit in an array of bytes.

I was planning on using it for Chess bitboards - https://en.wikipedia.org/wiki/Bitboard, but it could be used for say 8 booleans to the byte.

unsigned char getbit(unsigned char * bits,unsigned long n){

    return (bits[n/8] & (unsigned char)pow(2,n%8)) >> n%8; 
}

void setbit(unsigned char * bits,unsigned long n, unsigned char val){

    bits[n/8] = (bits[n/8] & ~(unsigned char)pow(2,n%8)) | ((unsigned char)pow(2,n%8) * val);

}

When I just tried it, at the end of the Quiz I just seemed to get a white page with a broken image
deutronium··on UK Investigatory Powers Bill: Politicians exempt themselves from new laws
I'm not sure how it's a positive feature at all, why should they be treated differently from the rest of us.
deutronium··on The UK Is About to Legalize Mass Surveillance
"The Investigatory Powers Act dramatically increases transparency around the use of investigatory powers." --

Doesn't that make it sound like they were monitoring people's web history already?

With 48 odd bodies able to access people's web history, it surely won't be long before this access is abused.

deutronium··on Homeopathic Medicine Labels Now Must State Products Do Not Work
Don't homeopathic medicines claim they work via water memory though, which has been debunked.

If you wanted to make use of the placebo effect from what I recall syringes have a more powerful effect than pills etc.

deutronium··on “Snoopers' charter” petition hits signatures target
http://www.independent.co.uk/life-style/gadgets-and-tech/new... - I'm very curious why the NHS need access to your browsing history, along with everyone else.

Wouldn't the CHIP draw a lot more power?

Edit: Just noticed someone above linked to https://getchip.com/pages/pocketchip guess it just needs more mAh batteries

deutronium··on Israeli firm can steal phone data in seconds
Regarding the iPhone 5c, the attack from Sergei Skorobogatov is very interesting.

deutronium··on IP Over QR Code
Very cool :) I wonder if you could potentially use colour to increase the data rate a bit? (although then it wouldn't be a standard QR code I guess)

http://www.jammarcade.net/backer-32/ -- I've got one of these devices, which was used back in the day, to store data on a VHS tape, in a similar way to what you're transmitting.

In the spirit of uncommon data transfer methods, here's my ridiculously slow version, using a cddrive:

To transmit 'hello' it takes around 13 minutes ;)

deutronium··on Hunting submarines with magnets
Cheers! That's a very good point.
deutronium··on Hunting submarines with magnets
This may be an incredibly stupid question, but I know they used gravimeters to map the ocean floor on subs.

And I recall an anecdote of snow fall on a roof effecting their results in a lab, could you possibly use them to detect other subs.

deutronium··on Diamonds Suck (2006)
I'm curious how difficult moissanite is to manufacture compared to diamonds, as I was under the impression diamonds require high pressure and temperature to make.
deutronium··on Qt binding for Go with support for all major operating systems
Not Qt, but I'm using https://github.com/gtk-rs/ with Rust, which is pretty cool, I've developed the GUI using Glade, which I load via Rust. I'm also using CSS, to style the interface.

This article from Ron Pattinson - http://www.europeanbeerguide.net/reinheit.htm provides a number of interesting opinions on the Reinheitsgebot

deutronium··on How to Make a Handheld EMP Jammer
If only I had such a lab :)

That's really interesting with respect to your plasma cutter.

deutronium··on How to Make a Handheld EMP Jammer
How about something like an Explosively pumped flux compression generator, I'm thinking there must be bits of EEPROM or equivalent in the phone that hold important info like the imei number, that if damaged, would render it unusable?
deutronium··on Ask HN: What are the hottest startups related to beer / brewing?
eebriatrade seem really interesting! I signed up to that a while ago, so that I can order a keg for christmas :)

Hmm, you can get eLua which runs on microcontrollers, I wonder how you would handle the graphics though.
deutronium··on Flightradar24 ADS-B Receivers On-board a Surface Ocean Robot
Oh gotcha sorry, I misunderstood that link
deutronium··on Flightradar24 ADS-B Receivers On-board a Surface Ocean Robot
Sorry I'm not sure what you mean, as I understand it, the ADS-B signals are just being acquired with a receiver on the 'boat' and then relayed via satellite.
deutronium··on Flightradar24 ADS-B Receivers On-board a Surface Ocean Robot
I would assume so yeah. I'd be interested to know if there's any reasonably affordable satellite system that you could use for closer to real-time data.
deutronium··on Flightradar24 ADS-B Receivers On-board a Surface Ocean Robot
I thought this was interesting "The GOMX-3 satellite orbits the earth approximately every 90 minutes at a speed of 27440 kilometers per hour" - https://blog.flightradar24.com/blog/tracking-flights-with-sa...

I was assuming it would be a geostationary satellite they would be using.

Nitinol motors seem pretty cool, such as https://www.youtube.com/watch?v=sscoMtJV0uY as an example of shape memory metal
deutronium··on String theorist Edward Witten says consciousness “will remain a mystery”
Does having consciousness mean we can't be completely deterministic?

Very nice! For some reason I thought it was for letters, and was wondering why it thought my 'h' looked like a '6' heh
deutronium··on Hacker Unlocks ‘High Security’ Electronic Safes Without a Trace
You can get the slides here - https://media.defcon.org/DEF%20CON%2024/DEF%20CON%2024%20pre...

It really is a clever attack!

I'm really surprised at the way he mentions the microcontroller tests if the key is correct or not, by simply looping through and breaking on an incorrect number.

deutronium··on How contactless cards are still vulnerable to relay attack
Even if you use distance bounding protocols, couldn't someone just use one of those contactless paypal machines, to steal your money directly?
