I was finally convinced to put my smaller tables into one large one, but exactly how big is too big for a MySQL table? I have a table with 18 fields. Some are TEXT , some are short VARCHAR(16) , others longer VARCHAR(100) . Right now we get about 200,000 rows a day, which would be 6 million+ a month. How big is too big? Does it matter how many fields you have, or just rows? There's not a great general solution to the question "How big is too big" - such concerns are frequently dependent on what you're doing with your data and what your performance considerations are. There are some fundamental

Trying to learn R. A question from an old stats text want's to know if there is a difference in break times at different construction sites. Trouble is, the text decided that each site employs a different number of workers. So, I am stuck and looking for help using ANOVA with unequal sample sizes. site1 <- c(34,25,27,31,26,34,21) site2 <- c(33,35,31,31,42,33) site3 <- c(17,30,30,26,32,28,26,29) site4 <- c(28,33,31,27,32,33,40) Try this one site1 <- c(34,25,27,31,26,34,21) site2 <- c(33,35,31,31,42,33) site3 <- c(17,30,30,26,32,28,26,29) site4 <- c(28,33,31,27,32,33,40) Data <- data.frame( Y=c

I'm trying to get the div width and height as the user changes it and submit that number to another page. I can't seem to figure out how to get the width and height though. <script> $(function() { $( "#set div" ).draggable({ stack: "#set div", preventCollision: true, containment: $('#main_content'), stop: function(event, ui) { var mydiv = document.getElementById("set"); var pos_x = ui.offset.left; var pos_y = ui.offset.top; var width = mydiv.style.width; ----THIS DOESN'T WORK var height = mydiv.style.height; ----THIS DOESN'T WORK var window_width = window.innerWidth; var window_height = window

I'm using em sizes: font-size: 2em; , as an example. But when I change my screen resolution to a lower one, I want that size to a smaller one. For that purpose, I tried this code: <script> if ( screen.width > 1600) { document.write('<style>#centered h1 { font-size: 2em; } </style>'); } else if (screen.width <= 1600 && screen.width >= 1360) { document.write('<style>#centered h1 { font-size: 1.7em; } </style>'); } else if (screen.width < 1360 && >

I've searched for it but i can't find a conclusive answer to my question... I need to know what is the storage size of a number(p) field in Oracle. Examples: NUMBER(1), NUMBER(3), NUMBER(8), NUMBER(10) etc... The storage used depends on the actual numeric value, as well as the column precision and scale of the column. The Oracle 11gR2 concepts guide says : Oracle Database stores numeric data in variable-length format. Each value is stored in scientific notation, with 1 byte used to store the exponent. The database uses up to 20 bytes to store the mantissa, which is the part of a floating-point
