Posted by Eric Grosse, VP Security Engineering We are constantly on the lookout for malicious activity on our systems, in particular attempts by third parties to log into users’ accounts unauthorized. When we have specific intelligence—either directly from users or from our own monitoring efforts—we show clear warning signs and put in place extra roadblocks to thwart these bad actors.
Object-Oriented D esign has been a powerful problem solving paradigm for many years now and it still continues to be a force, but as practiced traditionally it has also been limited in many ways. Any Architecture attempting to distribute objects across multiple nodes and processes while still trying to maintain object semantics soon encounters a scalability nightmare . The reasons for these limitations are a lack of constraints on object design around encapsulation and composition . Traditional D omain D riven D esign builds on the p rinciples of O bject- O riented D esign and inherits some of these same limitations.
I admit it. When I first heard there are actual tournaments for Rock-paper-scissors, sanctioned by the World Rock Paper Scissors Society, I laughed. I mean seriously, $50k to the winner of a game that requires no skill whatsoever? Absurd.
"A growing economy consists of prices falling, not rising." The stock market does not work the way most people think. A commonly held belief — on Main Street as well as on Wall Street — is that a stock-market boom is the reflection of a progressing economy: as the economy improves, companies make more money, and their stock value rises in accordance with the increase in their intrinsic value. A major assumption underlying this belief is that consumer confidence and consequent consumer spending are drivers of economic growth. A stock-market bust, on the other hand, is held to result from a drop in consumer and business confidence and spending — due to inflation, rising oil prices, high interest rates, etc., or for no reason at all — that leads to declining business profits and rising unemployment.

I've been using Hibernate for some time now and when I don't work on a hibernate project for a while I find myself doing the same mistakes I did the previous times So here is a sort of watch list for my self hopefully will be useful to someone else as well. You should always implement these methods in general but for your entities you should pay a bit more attention.The first thing you think when I say equals is probably to use the Id to distinguish between instance. Well, that's gonna cause you a lot of troubles. You need to keep in mind that you are working with db entities and not normal POJOs. When Hibernate is fetching objects is your using collections and hence equals and hashCode to know if an object you are looking for is in the session.
