Line item data is the holy grail for a number of players in the payment space. The merchants are understandably guarded about sharing this information.


The electricity grid is also extremely complicated system that many people don't understand. With any complex system, it grows to beyond the knowledge of the people working in it.

One thing to note is that many of the critical components on the electrical grid is controlled over the network. When I used to build tools for the electricity trading desk, we were handling market bids/asks and scheduling of the power plants.

Here's an example of the stuff that we were dealing with. This is the real time settlement point prices for ERCOT (the grid network in Texas): http://www.ercot.com/content/cdr/html/real_time_spp

We had systems that lay out prices that we were willing to turn on and ramp up power plants. If prices hit a certain point, we were committed to delivering that power. We made these decisions based on economics of the power plant (gas plant vs nuclear vs wind) and other factors (such as weather , time of day, whether the Cowboys were playing that day).

Anyways, my point is that all these systems are interconnected and rather complex. It doesn't take much for an error in one place to bring down a major part of the system.

Take a look at the 2003 Blackout: http://en.wikipedia.org/wiki/Northeast_blackout_of_2003

As with any engineering, you're never going to factor away all the breaks. You need to build a system that assume things will break and ensure that it's not catastrophic.

Also, I don't think it's fair to say that Wall Street doesn't understand software. There are some very smart people doing solid engineering there. Neither one of the footnotes that you had in your post support your statement that Wall St doesn't understand software.


If he's looking to hire someone, it would help if he included the name of his company or link from his post.

I ended up finding it in small letters under his profile picture.

Also, saying "hiring a co-founder" is basically like saying "hiring a wife". You don't hire either one of those if you're looking for a partner. If you're not looking for a partner, you hire a contractor that will get the job done.


Does anyone have a good recommendation for a writing/blog platform?

I am looking for something that is simple and non-intrusive that I can just put up random thoughts.

Medium and Svbtle seem good and clean, but I don't have an invite.


Isn't BTC's public ledger public? (https://blockchain.info/)

While it's possible to generate a new wallet to mask who the user is, the transaction flow can be traceable. This seems easier to trace than the flow of money through our banking system.


Yes, the BTC can be traced, but they cannot be associated with physical people until they identify themselves. Your anonymity is limited by trustworthiness of the person selling you the coins and the person you are buying physical goods from.


>>"Students should be warned that doing a paid internship can negatively impact your ability to finish up paying for school."

Students should be warned that crossing the highway blindfolded if unsafe.

Students should be warned that the stove could be hot if you leave it on.

At some point, people need to take personal responsibility for their action. They need to understand how their actions effect them positively or negatively and balance out those decisions. People need to understand that there is nobody that is going to hand hold them through life.


She's not complaining or asking to be handheld. She's warning her fellow students that working to make money will impact the ability to pay for school.

It's counter intuitive. It's not obvious at all. It's barely mentioned or talked about. It can cost (and it did cost her) a college degree.

I don't disagree with the sentiment of your remark, but it's completely out of place here. She's simply warning others not to do the same mistake, since it's an easy one to make.


When I clicked on the comment thread, I made a bet with myself that some jackass would've shown up within the first hour to bellow "It's your fault your academic advisor/student aid office lied to you."


The fact that one could get hit by a car crossing a highway blindfolded is obvious.

The fact that earning money in college could negatively impact your ability to pay for college is not obvious.

The warning is justified. Many people would not anticipate this.


Yes, there's an open API.


I make annual donations to my university's alumni fund because I would not be where I am without the opportunities given to me by my choice in college. I also want to give that opportunity to the next under privileged kid.

As others pointed out, wealth redistribution in this case is voluntary.


Zurb did a tech talk a while back. They found that the drop off rate for one of their long running processes dropped significantly when they added a red bouncy ball as an interstitial for any process that took more than 400 ms.


I wonder about why this is the case.

* Is it because we as users have been conditioned, through years of faulty software, to assume crap crashes/hangs when there are unexpected delays?

* Or is the majority of computing so fast and instantaneous that we can't bring ourselves to wait on something that doesn't have an immediate end in sight?


Does anyone know what the status is on the non-rel branch? It's still on 1.3.

What framework do other people using NoSQL data stores use?


It is highly unusual to use NoSQL as the main data store in Django (so much of the built-in functionality requires relational databases, so you end up net-negative). Most Django folks augment their relational database with some NoSQL bits.

We've been big fans of storing core data in Django models, but using things like key/value stores to store random extra bits that aren't exactly core to the model. Redis is great for this, or another model as triple store style GenericRelation if you need to query on it.

I don't imagine the nonrel branch will move again, its such a departure from core Django. Look into using Flask, as there aren't many "mature" frameworks that do NoSQL core.


What about hstore?


I've very limited knowledge about hstore, but have only heard great things!
