thwest··on Case Study: Real Time SMS polls at Zappos All Hands Meeting
5500 acres / 302 shipping containers = 18.2 acres per shipping container?
thwest··on The Apple Boycott: People Are Spouting Nonsense about Chinese Manufacturing
I refuse this appologia, especially the false dichotomy between an absolute minimum in worker benefits and the existence of jobs better than farming. Nike/Apple/Gap/Samsung all put substantial effort into their overseas operations and reap huge profits. Spending a fraction of their margins on creating healthy workplaces and increasing worker ownership could change the situation from lesser of two evils to a transformational endeavor. Given more free time, savings and ownership in the company she is helping to create, a Foxconn worker could turn around and mechanize the family farm. The only one to disappoint is Wall Street.
thwest··on The Apple Boycott: People Are Spouting Nonsense about Chinese Manufacturing
We should just have tariffs on imports that don't meet our labor and environmental standards.
thwest··on Why Google And Facebook Need To Go Dark To Protest SOPA
Why go completely dark? Partially put black censor bars over most of the search results. Throw in a prominent banner to a page explaining SOPA and a button to remove the censorship. Then there is less chance of users assuming some technical problem, and a greater chance for education.
thwest··on Poll: What keyboard layout do you use?
I spent a year using dvorak and did notice a slight comfort increase. I've since reverted to qwerty due to device inertia. Currently the biggest interface ergonomics problem I am trying to get through is using the mouse less in windows
thwest··on Machine Vision made Easy - SimpleCV
OpenCV is OSS maintained by Willow Garage. Intel provides the Intel Performance Primitives which implement basic filtering up through haar, segementation, optical flow.

Machine vision usually refers to the domain of industrial inspection where the scene contents are highly controlled, and computer vision usually refers to harder problems where someone is walking around a real environment with bad lighting and awkward perspectives.

thwest··on BankSimple invites first customers; rebrands itself as Simple
Oh but I wish you were a bank or credit union. How my deposits are used is something we should be able to negotiate about.
thwest··on Racism in Tech
I would ask people not to take the test immediately, but rather first spend time on the authors' distinction about implicit racial attitudes. Racial bias in this sense is entirely different than overt racism, but still as important. Admitting that you've unintentionally learned the statistical biases present in our culture is not admitting you're a racist. When you're ok with that statement (which can be difficult given the charged USian history of race!), take the test.
thwest··on For HN: Open access to scientific papers, a summary of the state of play
Have you seen much pressure for data driven science to reproduce code+data alongside the pdf?
thwest··on Elements of Modern C++ Style
Oh C++11 has template typedefs? Time to migrate my project.
thwest··on The 99 percent
Market liquidity is not the same as creating value. If you aren't investing on the same timeframe that it takes to create a business (3-5 years), you are simply exchanging money for money, not creating value. There is some minimum amount of liquidity needed for things to work at all, but massive amounts of liquidity is not good in and of itself. After a point market liquidity is a force for creating bubbles, not sustainable businesses.
thwest··on Peter Thiel launches Breakout Labs to fund bold early-stage research
This community also tends to have a software bias as well. Basic science often requires lots of high precision hardware which is not cheap.
thwest··on Beta Test: New York Startups Think Occupy Wall Street Has a Bad Pitch
To me this says more about the attitudes of technologists than anything about OWS. I also note that there is no Occupy Palo Alto going on.

Tech startups are at the bleeding edge of capitalism where it is a fun game. Which is great to see The System work! We need a pluralist economy with all types of organizations. Startups have to challenge existing hierarchy in certain dimensions (business model), but strictly follow existing hierarchy in others (profitability, exit strategy). I'll cite the pg-Monsanto event here.

There will always be a need to reconcile whatever structure exists in our cultural hierarchy with the broad needs of everyone that has to bend to the hierarchy we've chosen (or let happen). Athenian style democratic action is great way to do that.

It is more meaningful to measure how cultural hierarchy responds to the incoherence that is real democracy (considering every person's desires equally) rather than how people's desires submit to the existing hierarchy.

thwest··on Monte Carlo profiling
Yeah this is how Intel describes VTune's operation as well. The trick is that you can't make the measurements from inside your own code, you have to have an external process doing the interrupting. As a newbie I didn't know this. I took an internal framework meant for very coarse level profiling and applied it at an absurdly fine level. The result was spending much, much too long trying to make sense of the numbers.
thwest··on Amateur rocket launch reaches 121,000 feet
Yes camera calibration is a well known problem. You have some nice straight lines from the launch pad structure you should be able to do it with.
thwest··on Jwz: Google's pseudonym support "obvious bullshit"
What are the best alternatives for email?
thwest··on Ask HN: Getting back into the working world with a negative track record
Explain the risks as clearly as you can, and if your boss finds the risk acceptable, proceed. As long as you are communicating, it will be a project failure, not a personal failure. Don't be combative about it, make sure everyone fails and learns together :)

Good: clearly tracking the risks as the project progresses.

Better: pushing yourself to learn Perl and mitigate the risks to the best of your ability.

Best: spend some OT implementing it in Java and show her why it is better (or show yourself why it is not).

thwest··on Steve Jobs Succumbs to Alternative Medicine
The reports of Jobs' treatment elections are conjecture.

"although neither Apple nor those close to Jobs were willing to discuss the treatments he elected or the course of his disease," the community continues to assume that rumors about Job's health coming out of financial publications (Forbes) are somehow accurate.

This post is trite and condescending no matter how long it came after Jobs’ death. Dealing with death is a personal matter. You have no right to demand that anyone submit themselves to the cold, alienated approach of aggressive medical treatment. Let people pass with dignity, however they choose.

The purpose of life is not to be a mobile mass of cells for as long as technologically possible. In fact, the statistics show that people who skip the N+1th round of chemo and switch to hospice care have better outcomes. http://www.newyorker.com/reporting/2010/08/02/100802fa_fact_...

thwest··on DARPA's AlphaDog robotic pack mule is ready for battle (and awesome)
Ready for battle? Awesome? Both of these are plainly false. Obviously we have learned nothing from Metal Gear Solid 4...
thwest··on This Week in Compressive Sensing
It is not at all obvious how compressive sensing works! Even if you have a background in signal processing or linear algebra. Most people approach linear algebra to solve over-determined systems of equations, not under-determined systems. But it turns out you can validly pose the problem if you have some a priori knowledge of the structure of your signal.

Actually, the camera uses a single pixel, not a single bit. The measurements from pixel are from a 16-bit ADC so we get pretty good grayscale information. There are some single bit compressive sensing implementations, often used for radar where the SNR is low.

There's even a startup that is building commercial implementations of single pixel cameras. We work with the Rice researchers you linked to. http://www.inviewcorp.com/
