Comment Monitoring Grids (Score 1) 342

The biggest problems we've seen from a monitoring perspective is that most systems really do have a hard time scaling to large levels and being usable. [A common trick (and one we employ) is to have a multi-tier monitoring system in place, where one monitoring stack monitors the monitoring stack that is actually watching the service/hosts.]

Once one gets past that hurdle, the tricky part is dealing with the "it is OK if X% of my machines are down". Most monitoring systems that I've dealt with are based around the view that they are monitoring a single host/single service and not a collection of hosts where it is OK if chunks disappear. For those types of problems, one still ends up writing a lot of custom smarts it seems.

Submission + - Open Source Solution Breaks World Sorting Records

allenw writes: In a recent blog post, Yahoo!'s grid computing team announced that Apache Hadoop was used to break the current world records in the annual GraySort contest in the Gray and Minute sorts in the general purpose (Daytona) category. Apache Hadoop is the only open source software to ever win the competition. Apache Hadoop also won the Terasort competition last year.

Who wants a turn-based RPG anymore? It's all about the flashy graphics and real-time combat.

That's why it is interesting watching to see how successful Atlantica Online is going to be (or already is?). A turn-based MMORPG sounds horrible, but they've really done a great job at game mechanics. The irony is that they likely had to do F2P because of the impressions that turn-based gives, but they are probably making money hands-over-fist with the micropayment structure they've setup. It isn't usual to hear of people who have spent hundreds if not thousands of dollars on it.

Comment Probably HBase (Score 2, Insightful) 163

None of the articles say it, but they are probably talking about HBase. If this is the case, this is seriously old news.

HBase was started by the Powerset guys before being acquired by Microsoft. After the acquisition there was a lot of concern in the Hadoop community about whether the Powerset guys would be allowed to continue to contribute. They have, and as far as I can tell, the community is not particularly concerned about MS's involvement.

Kerberized NFS support is required for full NFSv4 compliance. You might be surprised to know that Linux, AIX, and NetApp (although their Kerberos support is ... lacking) all have the capability to do it. OS X has rudimentary support for v4, haven't tested its krb5 compliance.

Additionally, most stacks either out there or in development add Kerberized NFS support to v3 while they are adding v4.

On the emasculation of Twitter and Dirty Harry

Fail and You Hadoop is a library for writing distributed data processing programs using the MapReduce framework. It's got all the makings of a blogosphere hit: cluster computing, large datasets, parallelism, algorithms published by Google, and open source. Every four days or so, a nerd will discover Hadoop, write a “Basic MapReduce Tutorial with Hadoop” tutorial on his blog with some trivial examples, and feel satisfied with himself for educating the world about a yet-undiscovered gem. Comparatively, very few people actually use Hadoop in practice, and those who do don't write about it. Why? Because they're adults who don't care about getting on the front page of Digg.

Submission + - What is the best kind of GPS tracking system?

TheBiggestGnome writes: Hello Slashdot!

I currently work for a Furniture Store as their IT director. We have one location, two delivery trucks, and twelve employees. We will be opening another location soon, but that isn't our issue.

Our delivery drivers have seemingly stopped working as hard as they used to and are falling behind schedule almost daily. My boss has approached me and wishes to install a GPS tracking unit in each of our delivery trucks. He'd like to have an active unit that provides semi-realtime updates that is cost effective (I would assume under $500) with no [or low] monthly subscription fees. I would prefer the tracking unit use GPRS and not a cellular device to communicate to cut costs, as well as having some reports that show speeding and idle time. And with the addition of [possibly] adding two more trucks in three months, and definitely another two trucks in six months, we would like to know where our merchandise is at.

I've poured over tons of websites (some look a little more shady than others) but there is a lot of misleading information which makes finding a product that suits our needs extremely difficult. I've looked at the "GPS Police miniLINK," but I can't find any reputable sources that have used and like this product.

What does this acquisition mean for Microsoft and more importantly, Live Search?"
