adamgravitis··on Poll: What would it take for another company to poach you?
I'm actually doing pretty OK visualizing these results in my head... :-)
adamgravitis··on MtRed Bitcoin mining pool will be shutting down
As I've rapidly discovered, trying to calculate aggregate stats over the basis of Poisson arrivals... is a pain. To work out anything interesting, you end up studying piecewise-deterministic markov processes in more detail than you'd wish.
adamgravitis··on Just Landed
On the other hand, this issue reminds me of Peter Thiel's TedX talk, where he makes the argument that real technological invention may be slowing: http://www.youtube.com/watch?v=HOB7nezuQ7g

I agree assisting people to reach the airport on-time may morph into a larger corporate vision, but I disagree it's likely to contribute to solving cancer, making better fuel, or reaching strong AI. ...And it's arguably a distraction of rare talent from that calibre of problem.

adamgravitis··on The Minuum keyboard project: mobile keyboards reimagined
Incidentally, I really love the soundtrack. Does anyone know if this is just stock music from somewhere?
adamgravitis··on The Cost Of Free Doughnuts: 70 Years Of Regret
I seriously thought this was going to be about diabetes or sugar addiction or something :-)
adamgravitis··on Show HN: Weekend project, Intro.js
Regarding usabili.ca, the domain you're using... If you're "three geeks in Tehran", you really shouldn't be using a Canadian domain. Unless you're Canadians, or are incorporated within Canada.

Just saying.

adamgravitis··on Ask HN: How do you deal with Rabbit Hole Syndrome?
Heh. Are you Neal Stephenson? :-)
adamgravitis··on Apple Pulls 500px’s Mobile Apps From The App Store
"a monumental fuck-up." - no pun intended, I'm sure ;-)
adamgravitis··on Devops/Sysadmin Cheatsheet
That's not devops - that's system administration. Not complaining; it's still a well-presented list.
adamgravitis··on Show HN: UUID as a Service
Indeed. There's even a name for the anti-pattern: "nanoservice".

adamgravitis··on KGPU - Augmenting Linux with the CUDA GPU
Where is this useful? The bus speed across to the GPU is so slow, I thought it was only meaningful for near-autonomous operations.
adamgravitis··on I Don't Want To Be Part of Your Ecosystem
My brain had trouble parsing the headline:

I don't want to be part of your fucking (ecosystem) -vs- I don't want to be part of your (fucking ecosystem)

adamgravitis··on Atlas: A Human-Powered Helicopter
Both Todd and Cam are brilliant aero engineers. While not a fait accompli, this certainly isn't their first negotiation with nature...
adamgravitis··on From MIT, a cure for all viruses?
Thank you for posting this on HN! This is exactly the kind of underreported bleeding-edge engineering I hope to discover on places like HN.

It's very easy for mainstream journalists to jump on new technologies once they've been developed, but it's up to engineers and scientists themselves to make exciting potential directions better known.

adamgravitis··on Average Is Over
The author's sudden and poorly supported conclusion doesn't really fit. Because people with bachelor's degrees have the least unemployment, it is imperative we pass a GI Bill to ensure everyone gets a bachelor's degree?!

He's getting the causality wrong. It's not because they have bachelor's degrees that they're getting jobs. They're getting jobs because they're (minimally) bright and (minimally) ambitious.

Printing 100 million bachelor's diplomas "solves" the unemployment problem in much the same way that printing 100 trillion dollars solves our financial problems: not at all.

adamgravitis··on Two things about SOPA/PIPA and then I'll shut up
In fact, businesses (companies) are not permitted to donate to political parties in Canada. And this same "neo-con" government has lowered the maximum personal donation from $5000 per person to $1000 per person.

If anything, this has encouraged a more 'grassroots' approach to fundraising, as it's more the number of people you can engage, rather than a particular (wealthy) demographic.

adamgravitis··on A single line to 3 cashiers is ~3x faster than a separate line for each cashier
The parallel vs serial queuing problem is very well established within the operations research community.

And, IIRC, it's not that there's much impact to average performance, but rather that the variation (sigma) drops by a factor of n.

adamgravitis··on ActiveMQ: Not ready for prime time
The thing I've found about message queues is that it's pretty unimportant what platform they're based on. I used to be tempted to go with ActiveMQ "because it runs on the JVM", but that turns out to be pretty irrelevant.

No matter what your queue provider, you're most likely just using TCP sockets anyway, so don't think you need to be using Erlang just to take advantage of RabbitMQ.

Yes, this means the MQ can basically be thought of as a black box. But that's also kind of the point.

adamgravitis··on Paul Graham and his "no asshole" rule (Interview)
Funny, I always thought Paul would speak in received pronunciation... :-)
adamgravitis··on Conrad Black: My prison education
Indeed, as the above mentioned, he founded the Post.

Followers of the story (largely, Canada and UK) have seen quite a drama over the last few years. It's helpful to understand he is, in fact, a British Lord - after renouncing Canadian citizenship under a Prime Minister blocking the appointment due to a personal vendetta - and was convicted of defrauding shareholders under a law recently deemed by SCOTUS as open-ended and unconstitutional.

adamgravitis··on If you were hacking since age 8, it means you were privileged
Wholeheartedly disagree.

As evidence, the author mentions the late average age that the underprivileged "received" their first computer. As I recall, one Bill Gates began hacking at an early age, not because his privileged family showered him with cutting-edge technology, but because he bent a few rules to gain better access to a terminal through school.

Let's not confuse resourcefulness with privilege.

adamgravitis··on Tell HN: AeroFS - File Syncing Without Servers
That's pretty much Yuri's modus operandi.
adamgravitis··on Toronto Hacker News Night
Looking forward. Don't forget there's a StartupDrinks the night before at Elephant and Castle - if you don't mind hearing the latest about, er, Rails...
adamgravitis··on Toronto Hacker News Night
Hrm - GuestListApp just sent the confirmation, saying "error in parsing this message..." :-|
