Dilpil··on Stack Overflow's new Gaming site is in public beta
Funny how about 1 out of 10 posts is about dwarf fortress.
Dilpil··on Canada Immigration Law Changed, Skilled Worker List Reduces to 29
Electrical and Industrial seem to still be on the list.
Dilpil··on Indie (Game) Fund is open for applications
My first thought was "oh wow, some rich people who want to participate in the gaming industry, how cute".

But when I saw the team, wow. The creators of Braid, Fl0w and world of goo are all among the partners it seems.

Dilpil··on Machine learning revolutionizes software development
Ten times faster? Ten times? I find that completely implausible.
Dilpil··on [dead]
I don't understand- this is about the launch of a new air route? Why was there even a launch event?
Dilpil··on Should browsers have an expiration date?
Many corporate IT departments run old browsers because they make use of proprietary intranet web applications and don't feel like developing them on multiple platforms. To them, this system would seem pretty stupid, and indeed, would prevent them from ever upgrading into new expiring browser versions.
Dilpil··on Pi is Wrong
What about the fact that sin and cosine have such elegant Taylor series expansions if you use radians?

In radians, sin = x - x^3/3! + x^5/5! - x^7/7!...

In 'Double radians', we have a 2^n factor in front of each term.

Dilpil··on What Business is Wall Street In?
Which is the wiser way to deal with hackers:

Is it to enact hard to enforce ambiguous anti hacking laws, while at the same time individually patching each exploit with unrelated fixes?

Or is it to step back and analyze why a system has so much hackable complexity, and seek to fix the overarching issues that create security vulnerabilities?

I would much rather see fundamental suggestions about how to optimize the market for fairness from the ground up rather than patchwork fixes like the dollar a trade tax, or the 5 year tax break.

Dilpil··on Obama bemoans 'diversions' of IPod, Xbox era
Indeed. I wonder if the title is intentionally misleading, or if the writers had a different idea in mind when they wrote it?

Indeed, the strong controversy this articles headline will stir up proves Obama's (actual) point quite well.

Dilpil··on Crime in America keeps going down, yet the American public refuses to believe it
But that doesn't really get to the point of the article- why were there fewer real things happening when more people were getting victimized?
Dilpil··on Wargames: U.S. Cyberattack starts February 16 watched by all
How many people involved in this actually have any idea about how computers work?
Dilpil··on Adobe: 7 million people attempt to download Flash each month
I regularly fail to install flash on computers at libraries or even on my home computers. The installer is extremely buggy.
Dilpil··on Fundamental attribution error
One interesting point a proffessor of mine once made on the topic: The phrase "If I were them, I would.." is meaningless. If you were them, if you had an identical upbringing and identical genetic material, you would behave exactly as they do.
Dilpil··on [dead]
Any humor can be made to sound stupid by explaining it sarcastically. It still has value.
Dilpil··on Ask HN: My nephew wants to learn programming. What should I recommend?
XNA studio is nice because it comes with a finished game that you can edit, and there's no pointer nonsense to get tripped up on.
Dilpil··on How a swashbuckling breed of computer scientists nearly destroyed Wall Street
So lets see. A bunch of people bought stock. Stock rises and a bunch of people get rich. Somebody sells stock. A bunch of people get nervous and sell their stock, sending prices plummeting.

This story is as old as Wall Street itself. That quants were involved was incidental, thought it makes for some interesting twists.

Dilpil··on Thesixtyone Unveils a Gorgeous Redesign, Users Predictably Revolt
The new design is gorgeous, yes. No one is calling it ugly. But ugh, it is quite unusable.
Dilpil··on The Real Reason Outsourcing Continues To Fail
I wonder if this is why many foreign firms like to hire people who were educated in the US? Perhaps they have noticed that these people are, for reasons neither the employee nor the employer understand, better at dealing with western customers due to time spent with americans?
Dilpil··on Google, do not take Chinese netizens hostage
Perhaps Google's decisions have nothing to do with ideology. Perhaps they are legitimately concerned about IP theft and security, and are simply exiting china in the most PR friendly way possible.
Dilpil··on MeetingMix (YC S08) Gets Your Co-Workers To Cut To The Chase
This is exactly the technique that the more efficient managers I know use: make people commit to exactly what they want to say and discuss at the meeting beforehand.
Dilpil··on Google, Citing Attack, Threatens to Exit China
I don't understand, will they be invulnerable to Chinese hackers after removing the Chinese version of Google?
Dilpil··on Sick of waiting on hold? Try lucyphone! Snag an account w/ code = "LUCYCOMB"
Cynical answer: by making you wait, they encourage many people to hang up, reducing volume at peak hours, and allowing the company to hire fewer CSRs.
Dilpil··on Entrepreneurs Aren't Risk Takers - They're Arbitrageurs
If you ignore opportunity costs and assume no money is borrowed, then yes, there is no risk.
Dilpil··on Why you should do OpenGL and not DirectX
I was under the impression that DirectX was a more extensive API, and included support for more complex high level operations- is this untrue?
Dilpil··on How Good Are UW Students in Math?
Interesting premise, questionable conclusion. Kids can't do simple concept problems, so they need more drilling? Failure to calculate 1/.1 is not due to lack of practice, it is due to fundamental lack of understanding of fraction division. This is not a problem you fix via repeated long division of 4 digit numbers. This is a problem stemming from the fact that these students were never given a good idea of what the symbols they are being forced to move around really mean.

And who cares that they don't know the definition of cosine, or the formula for the area of a circle? These are not fundamental ideas for non engineers.

Dilpil··on Students Ace Textbook Physics While Struggling With Basic Understanding (video)
I've always thought dataAt(x) would be more correct then dereference(x)
Dilpil··on Russia may send spacecraft to knock away asteroid
If the Expected Value in human lives is 6 billion divided by 330,000 (18,800), it might be a worthy project.
Dilpil··on GSM encryption broken
Links to a registration prompt. If anyone is really interested in reading this, google the URL.
Dilpil··on US Air Force says decision-making attack drones will be here by 2047
How long did the atomic bomb take to develop? 10 years?
Dilpil··on Linear Algebra Done Wrong [pdf]
I am always amazed at textbooks that introduce axioms and then later (or never!) show why they are interesting. Do any mathematicians actually think in this way?
