similar to: SQLite: Pros, Cons and when to use it (Informative)

I wanted to share an article I recently wrote on my blog with all of you regarding using SQLite for your web-applications. The blog url is: http://rubyonrailsblog.com and the article is currently posted on the front-page. Your insights and feedback are appreciated and are always welcome. Also if you have a blog, please let me know and feel free to put a link to my blog up on your site. If you do,

R has very good GUI packages that I have used - R Commander RCmdr and Rattle rattle . Since I work on multiple packages with constraints of time, I almost always use the GUI rather go through the intricacies of command line . The log of these GUIs shows the relevant R command that was used, so you can actually learn the language also. I have written about the ease of learning R , if you begin

Hi, First of all thanks for all the answers .... all were very informative and helped me shape a better presentation. Although i received lots of emails saying that installation under Linux / Unix is easy .... still emails asking for help in installing R itself, or external packages and such crop more often than not on the list and for this reason i pressumed it is harder to install under Linux

I have a basic question, being new to EXT3. What are the pros and cons of using an external journal? Also, for a Terabyte-sized system, what should I use as the external journal's size? is there a general rule-of-thumb to follow when choosing the external journal's size? I know these are very basic questions, if they have been already answered in some FAQ, please let me know. Any

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail

I am the maintainer of its, but not it's original author. One of the main strengths of its is that it uses POSIXct dates. Zoo has the flexibility of using almost any date format, but I don't know if the other date formats can store hour, min, sec data. You might want to do a little exploring with each before you commit. I'll be happy to give you a hand if you decide to work with

My objective is to start having meta-data on objects that I create. For example, consider the following function: assign2 <- function(x, ...) { assign("x", ...) attr(x, "creation time") <- Sys.time() x <<- x } assign2("x", 1:4) "assign2" assigns to x the vector 1:4, and it then also adds the creation time of the object. (Hat tip goes to

I was thinking about running Wine on Interix (the POSIX layer of Microsoft's Services for Unix). There are a few apparent unknows: Would Wine load the .dll.so's? Since Interix uses PE for it's native format (running on Windows, duh), Would Wine load the .dll.so's? Would it reject them being in PE format and having the 'POSIX Layer' attribute set, or could we hack on a

Relative newbie so would welcome comments re structure of a self-referential relationship I''ve got. It''s started off similar to the Person HABTM friends in the Rails recipes books (working fine), but I needed to turn the join table into a full-blown model as I wanted to add attributes to it. Few tricky bits dealing with the new :through structure and understanding how :scope

I've read that certain operations performed on a matrix (e.g. ribind, cbind) are often much faster compared to operations performed on a data frame. Other then the "bind functions", what are the main operations that are significantly faster on a a matrix? I know that data frames allow for columnnames and rownames, and that each column in a data frame can have different data types.

Can anyone comment or point me to a discussion of the pros and cons of robust regressions, vs. a more "manual" approach to trimming outliers and/or "normalizing" data used in regression analysis?

I have Samba running without a PDC and I have some questions about the advantages for implementing one with Samba vs. the problems and disadvantages. Perhaps some kind souls can help me determine whether I should do this or not. We have three offices connected by a Checkpoint VPN, plus people "on the road" using their SecureClient tool. We want everyone to be able to get to all the

In a previous thread, Tom listed advantages (reproduced below) of Proxy ARP over NAT. They are great reasons, but I have one reservation. By using private addresses with NAT for servers in my DMZ, I can granularly allow specific traffic, such as to/from the SMTP gateway/relay in the DMZ, to connect inbound from the DMZ to an internal (LOC) mail server, and know that it comes only from a

Hello Boys and Girls and Everybody. I have recently started using a Macintosh computer to replace the dinosaur of an unbelievably unreliable PC that I have been using for the last 10 years. So far I have been very pleased. I have been using OpenOffice for quite a while now as I find it is mostly superior to Microsoft Office in many ways, HOWEVER - OpenOffice lacks the Voice Recognition Software

Hi, I am doing a very informal presentation for my office about R capabilities to deal with and analyze spatial data, display data and maps, and connections with GIS. I've used in my presentation info from the CRAN, the spatial Task view, and the more striking graphics examples from http://addictedtor.free.fr/graphiques/thumbs.php and NCEAS

2009/3/7 Rosanne DiMesio <dimesio at earthlink.net>: > I can think of one possible benefit. There are a lot of apps without maintainers, and there might be users of those apps who would be willing take a few minutes to post bits of useful information in a wiki, but don't want the responsibility of being a maintainer. Sure, they could just post info in a comment, but user comments are

Bear with me, this is CentOS related. :) I have a python CGI that's behaving weirldy on Whitebox systems that've been switched over to CentOS 4 (ages ago, no other problems to speak of aside from this one). I've broken the problem down to a minimal test case... 1. Create a small database # sqlite3 /tmp/testcase.db 'CREATE TABLE testtable ( date date primary key unique, name

I''ve been editing a rails app on Windows for a little while now. I just checked it into source control and started editing on my iMac. Everything seems to run normally, except that when I attempt to modify the database in any way (I''m running sqlite), I get a weird error: "cannot start a transaction within a transaction"

Dear list, i have installed SQLiteDF (and SQlite 3.5.3 too) After the suggested dataframe generation iris.sdf <- sqlite.data.frame(iris) i have close R and than restart it for verify the correct load of dataframe : the file data1 is saved in the usual folder .SQLiteDF after the command : attachSdf("c:/R/Report/.SQLiteDF/data1.db","iris.sdf") R give this error
