阅读更多关于 MS Access Front-end: Does each user need their own copy?

问题 In one of my Stack Overflow questions about MS Access front-ends, an SO community member suggests that each user should have their own copy of the .MDB or .ACCDB front-end file: Don't put the database on a network drive and share it with users. Give each user their own copy. Is this necessary? What are the problems associated with multiple users accessing the same file? The estimated number of users for my future front-end is currently 5, possibly growing to 10-20. 回答1: It is not necessary if

阅读更多关于 Image Optimization Using Google PageSpeed Insights and Apache mod_pagespeed

问题 I'm looking to get as close to a 100/100 page speed score as possible. The only issue preventing this is images at this point. As seen in the below image, the native image size is 500x500 but rendered at 327x327, the problem is that these images are responsive, so depending on view port they can be anywhere from 210x210 to 500x500. Google is crawling the site where these images are rendered at 267x267, I found this out when downloading the Google PageSpeed optimized content. But depending on

Joomla 2.5: assign user to usergroup from front-end

阅读更多关于 Joomla 2.5: assign user to usergroup from front-end

问题 I have statically defined user groups with statically defined access rights. And I want to be able to change the user group for given user from the front-end using some module.

阅读更多关于 Is Bootstrap 3.3.7 safe and secured if “data-target” attribute is unused?

问题 There is a security vulnerability regarding Bootstrap 3.3.7. It says that "Affected versions of this package are vulnerable to Cross-Site Scripting (XSS) attacks via the data-target attribute." I am wondering if v3.3.7 is safe to use if the "data-target" attribute is not used. 回答1: The so called ' vulnerability ' only occurs if the data-target value relies on data injected by something external (directly or indirectly) AND is shown on a page where other users than the attacker are affected.
