Visualizing A Pulse


This amazing new technology from MIT lets you see a pulse (for example) by comparing slight changes in color at the pixel level. It’s crazy, but you can see blood flow and whether a baby is breathing. You could also presumably use this to tell if something is human or android. The code is posted online if you have MatLab, or you can upload your own video here and test it out.

It’s weird how much further we could go with imaging. There are already cameras that let you change the focus after (Lytro) and the new Blackberry 10 has a time shift mode that lets you rewind part of a photo (a face in a group shot) to get the perfect expression without changing the rest of the frame. And this stuff is all out there and shipping. Cool.

Jack Point: “these acts go under the radar because they’re on what my friend Dinidu calls ‘minorities within minorities’. The attacks are no less awful, however, and it’s sad the mainstream Muslims and Christians are not speaking out,”...

sharanga: Good constructive criticism.

sharanga: >the electorate is too ill-informed to decide This is almost always true in any country. It’s one of the greatest faults of democracy. The electorate is ill-informed and as public choice theorists put it, systematica...

The Southern Expressway Bus (11)

Jack Point: Wy can’ these MORONS publish the damned timetable? Is that such a hard thing to do ? We have to go round in circles looking for info, no one knows exactly. Every website says contact 1919 but those idiots are only available...

The Cantaloupe Crash (10)

Iqbal: 5.5 million is a lot of money. Sounds about right. OMG 7 million for a wedding? Who organised it Cantaloupe? Did the poruwa crash doen around you? Either way you got ripped off machan. You ain’t no math wiz for sure. More like dim wit.

Iqbal: Indi, I think the official revenue figure was more like Rs 55 million for this Cantaloupe event. Which gives the directors pretty much what you say. I pity the fools that paid such an amount to have their NYE ruined.

Math Whiz: So there were 3500 tickets right? Normal Tickets were Rs. 10,000/- and VIP Tickets were Rs. 13,000/-. Just for the sake of argument let us go with the higher number of Rs. 13,000/- per ticket: 3500 X 13000 = Rs. 45,500,000/- There are 4...

Ali Baba And The NSA (1)

sack: I think you are forgetting the fact that most of the NSA type work (NSA is one among many) is done by private companies. In theory you can say that NSA employees are employees of the government who is doing a duty rather like soldiers. But...

What A Colombo Revolution Might Look Like (Thailand)

There’s a section of Sri Lanka – call them UNPers, elites, ESE, Ceylonese, whatever – that really really dislike Mahinda Rajapaksa and everything he represents. They’d like to see him thrown out of power at the least and tried as a war criminal at the most. This amorphous population, however, cannot beat him in elections and many don’t even vote. They do have disproportionate international connections so are featured a lot in international coverage of Sri Lanka, but they’re not especially influential within. I generalize because I’m talking broadly about a community I am or moreso was a part of.

Ali Baba And The NSA

There’s been a lot of talk about Edward Snowden and the NSA, specifically whether he should be hanged by his neck till dead or treated as a whistleblower. I lean towards the whistleblower side, largely because it’s really hard to take the side of a monolith like the NSA over one human being. There are a few points which have been bugging me.

Anti Christian Christmas

Shamefully, places of worship were attacked over the holidays – both Christian and Muslim. In this case the attacks seem to have been Muslims attacking Sufis (a sect) and claimed Buddhists attacking evangelical Christians. Both of these acts go under the radar because they’re on what my friend Dinidu calls ‘minorities within minorities’. The attacks are no less awful, however, and it’s sad the mainstream Muslims and Christians are not speaking out, let alone Buddhists.

The Cantaloupe Crash

Cantaloupe is an events management team that grew out of the old Colombo Nightlife crew, AFAIK. I’ve met a few of the directors and they’re nice enough, though those sort of events and nightclubs (Amuseum) are not my scene at all. They are, however, a scene which a lot of people seem to enjoy. Underneath that lifestyle, however, there’s always an undercurrent of violence and danger. This New Year’s Eve nobody shot off guns (which happens in Colombo), but an entire stage did collapse, injuring hundreds. There are limited ways to respond to such disasters, but not being prepared, not getting the injured to hospital as a priority and continuing the party have not represented Cantaloupe or the Hilton well.
