Free Online Version of Core Servlets and JavaServer Pages (Second Edition) in PDF Top 10 Cloud Computing Startups in Boston Depending on who you talk to, cloud computing is either one of the most significant technology transformation since the advent of the world wide web, or one of the most over-hyped fads since virtual reality. For today’s post, I thought I’d do a round up of the top cloud computing startups in the Boston area. But first, a confession: classifying a company as in or out of the cloud computing market is subjective. It reminds me of classifying Internet companies back in the mid-1990s (does having a web site make you an Internet company?), and is further complicated by the fact companies are scrambling to re-brand themselves with the cloud. If you haven’t noticed, Salesforce.com is now known as “the enterprise cloud computing company”, and Akamai is “the leading provider of cloud optimization services." So I have adopted a simple rule of thumb: if you think you’re a cloud company, then for the purposes of this top 10 list, I’m going to call you a cloud company. Conclusions
Dynamic Programming Practice Problems This site contains an old collection of practice dynamic programming problems and their animated solutions that I put together many years ago while serving as a TA for the undergraduate algorithms course at MIT. I am keeping it around since it seems to have attracted a reasonable following on the web. Eventually, this animated material will be updated and incorporated into an algorithms textbook I am writing. -- Brian Dean To view the solution to one of the problems below, click on its title.

Dynamic Programming Archives - GeeksforGeeks A Derangement is a permutation of n elements, such that no element appears in its original position. For example, a derangement of {0, 1, 2, 3} is {2, 3, 1, 0}. Given a number n, find total number of Derangements of a set of n elements. Examples: Input: n = 2 Output: 1 For two… Read More » Given a “m x n” matrix, count number of paths to reach bottom right from top left with maximum k turns allowed. What is a turn? Given a matrix where every cell has some number of coins. Given an array of numbers and a constant k, minimize size of array with following rules for removing elements. Given a linear equation of n variables, find number of non-negative integer solutions of it. Given a n*n matrix where numbers all numbers are distinct and are distributed from range 1 to n2, find the maximum length path (starting from any cell) such that all cells along the path are increasing order with a difference of 1. Consider the below problems statement. Given a string consisting of only A’s and B’s.
Why You Should Never Use MongoDB « Sarah Mei Disclaimer: I do not build database engines. I build web applications. I run 4-6 different projects every year, so I build a lot of web applications. I’ve picked the wrong one a few times. The project Diaspora is a distributed social network with a long history. But they hit a nerve. Diaspora was the first Kickstarter project to vastly overrun its goal. As a result of their Kickstarter success, the guys left school and came out to San Francisco to start writing code. They ended up staying at Pivotal for more than two years. That’s a lot of buzzwords. “Distributed social network” If you’ve seen the Social Network, you know everything you need to know about Facebook. A screenshot of the Diaspora user interface There’s a feed in the middle showing all your friends’ posts, and some other random stuff along the sides that no one has ever looked at. The Diaspora infrastructure is not located behind a single web address. Pods of different sizes communicate with each other, without a central hub.
How This Web Site Uses MongoDB Warning: this post is intended for developers. It gets a bit technical! Sometimes I'm asked what platform we're running the Business Insider on. Well, we're using LAMP, of course: Linux, Apache, Mongo, PHP. After I get past defending our choice of PHP to the haters (you know who you are!) So what's Mongo? MongoDB is an open-source, non-relational database that combines three key qualities: scalable, schemaless, and queryable. Mongo's design trades off a few traditional features of databases (notably joins and transactions) in order to achieve much better performance. So Mongo occupies a sweet spot for powering web apps. Full disclosure: TBI and 10gen, the developers of MongoDB, share certain investors and board members. Here's why and how we use it: It's Scalable TBI gets fairly high traffic, and we're growing quickly. When we do eventually need to scale up further, Mongo has automatic sharding features to distribute data and load across multiple boxes. Document-oriented, not relational

The 20 Startups Marissa Mayer Has Acquired at Yahoo Yahoo acquired app maker Lexity on Wednesday, the company's 20th since Marissa Mayer became CEO of Yahoo a little more than a year ago. Twenty startups is no small number, especially when you consider that in just 13 months, the 18-year-old company has boosted its acquisition count by nearly a quarter. The majority of these acquisitions have been small — five were purchased for only $16 million together — and were more often for talent than specific products. Generally speaking, Mayer has sought out companies that have built promising, if unsuccessful, consumer-facing mobile apps. In a few cases, the acquisitions were for more than talent. Here's a look back at the 20 startups Mayer has acquired so far during her tenure at Yahoo: The List 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.

Henry Vilas Zoo : Home Page Back to Busch Gardens Jenny and I enjoyed a brief trip to Florida this past weekend, attending to family business and spending time with good friends. Among the highlights of this adventure was a day spent at Busch Gardens. This was my first visit to the park in over 20 years, and I was amazed by how much the place has changed. Expanding from its humble beginnings as a garden and zoo tacked onto a brewery, Busch Gardens has struggled to compete with nearby Disneyworld. The fact that the park charges Disney-like prices probably doesn't help matters. Back then, Busch Gardens borrowed liberally from colonial-era "Dark Continent" language and imagery. Busch Gardens has changed a great deal over the past couple decades, now attracting guests with increasingly spine-bending rides, ritzy performances, holiday themes, and pop culture tie-ins. No matter how much the park has changed, Busch Gardens delivers plenty of jaw-dropping encounters with the natural world.
