user-experience

The user of the ASP.NET web app I'm building can select colors for use on some of the elements (e.g. buttons/titles) to facilitate some degree of personalisation. The problem is that by default the text on those layers is black...what I'm trying to do is to evaluate the HEX value chosen by the user through a picker, and switch between black and white text programmatically - this can be in JavaScript, or in code behind. The crux of the problem is that I'm just not sure how to evaluate the HEX to make the decision whether the proximity of the chosen color to black is too close to use black text.

I need a facebook style notification, but getting something that looks nice cross browser seems tricky. For example, different browsers seem to treat paddings differently, resulting in weird looking notifications. What is the best cross-browser way of ensuring the notifications show up nicely? Not adverse to using javascript, but pure css is of course preferable Titus The best way to achieve this is by using absolute positioning : /* Create the blue navigation bar */ .navbar { background-color: #3b5998; font-size: 22px; padding: 5px 10px; } /* Define what each icon button should look like */

i'm trying to figure out how to layout a simple dialog in WPF using the proper dialog units (DLUs). i've come up with a simple r example, that cuts straight to the problem: You can check the Windows UX Guidelines to see where these measurements come from. The short version is: dlu = dialog unit dlu is based on the font size ( items change with user's font size ) a horizontal dlu is different from a vertical dlu ( dlu's are not square ) This comes from the definition of a dialog unit: the average character is 8dlus high by 4dlus wide . Georgia 14pt: If you use a smaller font (i.e. 8pt Tahoma

Lets say we have a simple example as below. <input id="filter" type="text" /> <script> function reload() { // get data via ajax } $('#filter').change($.debounce(250,reload)); </script> What we're doing is introducing a small delay so that we reduce the number of calls to reload whilst the user is typing text into the input. Now, I realise that this will depend on a case by case basis but is there an accepted wisdom of how long the debounce delay should be, given an average (or maybe that should be lowest common denominator) typing/interaction speed. I generally just play around with the value

What is the idiomatic python way to hide traceback errors unless a verbose or debug flag is set? Example code: their_md5 = 'c38f03d2b7160f891fc36ec776ca4685' my_md5 = 'c64e53bbb108a1c65e31eb4d1bb8e3b7' if their_md5 != my_md5: raise ValueError('md5 sum does not match!') Existing output now, but only desired when called with foo.py --debug : Traceback (most recent call last): File "b:\code\apt\apt.py", line 1647, in <module> __main__.__dict__[command] (packages) File "b:\code\apt\apt.py", line 399, in md5 raise ValueError('md5 sum does not match!')

I need to generate some passwords, I want to avoid characters that can be confused for each other. Is there a definitive list of characters I should avoid? my current list is il10o8B3Evu![]{} Are there any other pairs of characters that are easy to confuse? for special characters I was going to limit myself to those under the number keys, though I know that this differs depending on your keyboards nationality! As a rider question, I would like my passwords to be 'wordlike'do you have a favoured algorithm for that? Thanks :) Here are the character sets that Steve Gibson uses for his "Perfect
