20 lines of code that will beat A/B testing every time - Steve Hanov's Programming Blog
5 hours ago
"""
With a simple 20-line change to how A/B testing works, that you can implement today, you can always do better than A/B testing -- sometimes, two or three times better. This method has several good points:
* It can reasonably handle more than two options at once.. Eg, A, B, C, D, E, F, G, …
* New options can be added or removed at any time.
But the most enticing part is that you can set it and forget it. If your time is really worth $1000/hour, you really don't have time to go back and check how every change you made is doing and pick options. You don't have time to write rambling blog entries about how you got your site redesigned and changed this and that and it worked or it didn't work. Let the algorithm do its job. This 20 lines of code automatically finds the best choice quickly, and then uses it until it stops being the best choice.

Twitter Engineering: Improving performance on twitter.com

"""
To improve the twitter.com experience for everyone, we've been working to take back control of our front-end performance by moving the rendering to the server. This has allowed us to drop our initial page load times to 1/5th of what they were previously and reduce differences in performance across browsers.
On top of the rendered pages, we asynchronously bootstrap a new modular JavaScript application to provide the fully-featured interactive experience our users expect. This new framework will help us rapidly develop new Twitter features, take advantage of new browser technology, and ultimately provide the best experience to as many people as possible.

Yes, “people in a group do, individually, become less likely to help. It’s the volunteer dilemma: ‘If there are 7 billion people who could save the world, why should it be me?’ ” Krueger says. But drill down, and the picture grows more complex. In situations where there’s a clear threat—when someone is trying to extinguish a raging car fire, rather than merely struggling to change a flat tire—the bystander effect actually diminishes. “It’s counterintuitive,” says Krueger. “As the costs of a behavior become higher, you should be less likely to help.” Why that’s not so lies deep in our lizard brains. We know danger when we see it, and when we do, it induces higher levels of arousal and, therefore, more propensity to help. Even more heartening, when the costs of intervention are physical—a punch in the face or being run over by an oncoming train, instead of merely being late for work—“the bystander effect goes away,” Krueger says. And if the perpetrators are still on scene, the bystander effect can turn positive

Why Sugar Makes Us Sleepy (And Protein Wakes Us Up) | Wired Science | Wired.com

"""Although the scientists assumed that the inhibitory presence of glucose would more than compensate for the excitatory influence of protein, that hypothesis turned out be incorrect. Instead, consuming even a little protein canceled out the curse of sugar, especially when the foods were consumed simultaneously. (When the animals ate protein first, and then swallowed a chaser of glucose, orexin neurons still showed a decrease in activity. So make sure your dessert has some protein in it.)""""

Sucrase, and other sugar digestion proteins are extremely efficient and break the bond almost instantaneously. That is, if the bond is still intact. The bond is often broken by acid hydrolysis when sucrose is placed in acidic solution, such as, soda pop.
Regardless of where it is broken though, it makes no difference, because both are taken up by the intestine in exactly the same way. The fact is that humans can't absorb sucrose (or any other disaccaride for that matter). To get sugar, from food, past the brush border and into the blood, you need to break the aforementioned bond. Glucose and fructose are then taken up independently.
