Becau­se Boot­strap events are not name­spa­ced until they rele­ase ver­sion 3.0 (see https://​github​.com/​t​w​i​t​t​e​r​/​b​o​o​t​s​t​r​a​p​/​i​s​s​u​e​s​/​3​736), they con­flict with each other. It cau­ses for instan­ce clo­sing modals when swit­ching accor­dion tabs — they both listen to „hid­den” event. A sim­ple, glo­bal solu­tion is not to use data-toggle=„collapse” but fol­lo­wing code (that atta­ches „live”, 1.9.x jQu­ery style):

$(document).on('click', 'a.accordion-toggle', function(event) {
    event.preventDefault();
    var parent = $(this).parent().parent(),
        body = parent.find('.accordion-body');
        
    // hide currently shown group
    parent.parent().find('.accordion-body.collapse.in').collapse('toggle').on('hidden', function(event) {
        event.stopPropagation();
    }); 
    
    // show newly clicked group
    body.collapse('toggle').on('hidden', function(event) {
        event.stopPropagation();
    });
});

When you get reports that some people get e‑mails from Round­cu­be that have ATT####.dat attach­ments, check if they­’re using Micro­soft pro­grams, espe­cial­ly Outlo­ok Express. They don’t (of cour­se) imple­ment the most recent RFCs, so if attach­ment name con­ta­ins dia­cri­ti­cal cha­rac­ters (such as Polish ą, ć, ś, etc.) it gets cor­rup­ted. When using Round­cu­be, the solu­tion is quite sim­ple — search the main con­fig file for „mime_param_folding” and chan­ge its value from 0 to 1.

A wor­ka­ro­und is quite sim­ple — make Net­be­ans think .pro­per­ties are .ini files. The draw­back is that .ini edi­tor seems to acti­va­te the PHP plu­gin. I have­n’t noti­ced it to slow down the IDE though.

I have /tmp and /home on dif­fe­rent par­ti­tions. When try­ing to move a file from /tmp to /home using File.renameTo() — it fails. Turns out one has to copy and dele­te the file him­self, rena­me­To works only insi­de sin­gle partition.

It turns out that Inter­net Explo­rer caches AJAX requ­ests (how cle­ver). If you’re using $.ajax(), you can pass cache: fal­se option to it, but if — like me — you’re using $.get() and $.post(), just use

$.ajaxSetup({cache: false});

some­whe­re at the start of your script.
