I am running currently about 9 servers at home but they take up a lot of space and the cabling is driving me mad. Is there any alternative to blades for a home based cluster?
I am currently using evernote but I have since moved to emacs for many tasks so I would like to access everything from emacs. How can I move all my evernote data to emacs-org mode?
I am considering which OS and filesystem to use on some new servers I have and am considering either Free BSD with ZFS, or Linux with BTRFS.
The programs I have run on both systems, so the only issue is reliability of the filesystems and performance, etc.
I am looking at a cassandra cluster, but the administration effort seems to be quite high. Is there any way I can configure Cassandra to rebalance nodes automically as new machines are added, some are turned off or temporarily unavailable, etc?
I'm using Emacs on different environments and unsure of which version to use so that they all behave the same as I hear there are differences between XEamcs, Emacs, and some other versions. Which should I use?
By the way, I am not looking to start a flame war with this post, I just want a version of emacs that runs the same everywhere which is the whole point of me wanting to switch to emacs.
has anyone got Riak working on Solaris or OpenSolaris? When I try to compile it I get:
user@opensolaris:~/riak# gmake all rel
./rebar compile
/usr/bin/env: No such file or directory
gmake: *** [compile] Error 127
user@opensolaris:~/riak# mkdir /usr/bin/env
mkdir: Failed to make directory "/usr/bin/env"; File exists

Is it possible to build a performant cluster for the home based on something like a plug pc:

I realise the Marvell Plug PC is not very powerful but in a couple of years I could imagine them starting to get dual cores and more RAM
I spend alot of my time in Emacs, and move between Windows, Linux, and Mac OS at least once a day since these are the machines my company has available to use. I spend alot of time in gmail using gmail folders too, and would like to find a cross platform email client for emacs which can support gmail too.
Note: I would like to find a client which is "stable", and has good support and documentation.
I'm trying to start a program in OS X and I get the message:
Port already in use: 8080
I tried LSOF to find out who is using the port but it doesn't have the information. Is there any way I can find out who is using this port so that I can then kill the process?
What is the most powerful home PC you can buy for under $10,000?
It must be able to run Ubuntu Linux 64, and will be used to host multiple VMs for high performance cluster system development

Ahmed Alomari, Senior Director, Oracle Applications Performance talks with Cliff about about improvements that have been made to PeopleTools 8.4.8 and in the HCM area for Enterprise 8.9 as well as key benefits of using the Oracle 10g database and Oracle 10g Application Server.
Cliff speaks with Ahmed Alomari, Sr. Director, Oracle Applications Performance about key performance improvements that have been made to Oracle's E-Business Suite 11.5.10, the top 3 tuning tips to improve Workflow performance, why customers should adopt Oracle Applications Tablespace Model, Java monitoring, and J2SE 5 performance improvements.
Could mapreduce be used to implement a webserver?
I'm thinking something like when a request comes in then the request sits on a queue, until a server is free to process it? Or am I missing the point here?
I want to delete all the records where field name class="10010" from Table A and AentryId = BentryId from Table B.
if i delete the entryId 12 which matches className=10010 from Table A and the same time that same id should delete from Table B also.
Table A:
AentryId className
12 10010
13 10011
14 10010
15 10011
Table B:
BentryId name
12 xyz
13 abc
14 aaa
I am creating a document database and I have to decide on a structure for the records which will be represented as strings. The database has to be able to be read from and written to using as many languages as possible using stable libraries in an efficient way. What are the relavant issues I have to consider, and what would you suggest is the ideal format?
I recenty asked a question about parallel programming algorithms which was closed quite fast due to my bad ability to communicate my intent:
http://stackoverflow.com/questions/2407631/what-is-the-most-useful-parallel-programming-algorithm-closed
I had also recently asked another question, specifically:
http://stackoverflow.com/questions/2407493/is-mapreduce-such-a-generalisation-of-another-programming-principle/2407570#2407570
The other question was specifically about map reduce and to see if mapreduce was a more specific version of some other concept in parallel programming. This question (about a useful parallel programming algorithm) is more about the whole series of algorithms for parallel programming. You will have to excuse me though as I am quite new to parallel programming, so maybe MapReduce or something that is a more general form of mapreduce is the "only" parallel programming construct which is available, in which case I apologise for my ignorance
