• Is it a good practice to have trim in setter?

  - by zibi

  I'm doing a code review and I noticed such a code: @Entity @Table(name = "SOME_TABLE") public class SomeReportClass { @Column(name = "REPORT_NUMBER", length = 6, nullable = false) private String reportNumber; ..... public String getReportNumber() { return reportNumber; } public void setReportNumber(String reportNumber) { this.reportNumber = StringUtils.trimToNull(reportNumber); } } Every time I see trimming inside of a setter I feel that its not the clearest solution - what is the general practice with that issue?

• How do I get this validationTextBox to focus?

  - by Anurag Chaudhury

  After performing an ajax request if the input in the form was wrong I am trying to get this validatationTextBox to be focussed on and display an indicator message showing the problem. The code is: dijit.byId("passwordField").focusNode.focus() The form element is as mentioned a validationTextBox. The matter that is confusing me even further is that before in dojo 1.5, this piece of code was simply dijit.byId("passwordField").focus() and this worked fine. How can I fix this?

• Which MySQL Datatype to use for storing boolean values from/to PHP?

  - by Beat

  Since MySQL doesn't seem to have any 'boolean' datatype, which datatype do you 'abuse' for storing true/false information in MySQL? Especially in the context of writing and reading from/to a PHP-Script. Over time I have used and seen several approaches: tinyint, varchar fields containing the values 0/1, varchar fields containing the strings '0'/'1' or 'true'/'false' and finally enum Fields containing the two options 'true'/'false'. None of the above seems optimal, I tend to prefer the tinyint 0/1 variant, since automatic type conversion in PHP gives me boolean values rather simply. So which datatype do you use, is there a type designed for boolean values which I have overlooked? Do you see any advantages/disadvantages by using one type or another?

I can't remember where I saw this but does anyone have any links or example code which show examples of how to use jquery to style form elements?

• Must declare function prototype in C?

  - by Mohit Deshpande

  I am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compiler, or gcc, under the Code::Blocks IDE)

• Is `std::string(strerror(errno))` dangerous?

  - by StackedCrooked

  At some places in my code, I print debug messages like this: int ret = getLinkSpeed(device.getSysName(), linkSpeed); if (ret < 0) { logDebug("Failed to obtain port speed for this device. Error: " + std::string(strerror(errno))); } From the documentation it is not entirely clear if strerror will return 0 under certain conditions (which would cause my code to crash). Does anyone know if it's safe?
