RGnumeric real time refresh?
I have data that comes in every 7 seconds or so and I'd like to display it in a spreadsheet, and possibly take user input from the spreadsheet. I have installed RGnumeric and written an appropriate R function that reads, manipulates and displays the data by writing via RGnumeric to a spreadsheet. However, the results of this are not displayed until the R function returns, so refreshing by

Revision: post on Intro to R lecture
Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

TIP for broken ARIN whois
This works for me on Centos 5.6. It may assist newcomers to the Linux world of Centos. whois 51.51.51.51 produces a normal and conventional display of data. However since ARIN, the North American registrar of IP addresses, "modernised" its WHOIS processing, a query to whois 64.64.64.64 will produce a one line summary of possible matches, which always includes ARIN, but omits the

Linux HA may not be the best choice in yoursituation. High Availability using 2 sites
In a nutshell and very first of all, you need at least 2 internet connections. Those ISP must be willing to setup BGP peering between your routers and theirs. Once that agreement has been made, you need to get their AS Numbers and submit the ASN request located on ARIN's website (http://www.arin.net). After some paperwork and money exchanges, ARIN assigns you an AS number. At that point,
