How to speed-up generating PDFs via TMS Flexcel

In my current project we needed to generate lot of PDFs from the same excel template.  For this we use TMS Flexcel library. It is a simple library for generating Excel or PDF files in .NET.

How to call any function as a $filter in AngularJs

Recently I had this little trouble. I had a simple angular controller, which filtered some array of items. I did not want to define the filter in a “global space” because I knew it will be used only by this one controller. So this first thing was to define the custom filter function. Like this […]

I tried to restart my machine, check versions of Firefox and Selenium (both were up to date), restart Visual Studio, clean solution. Nothing worked.  There was not even an exception description.

Překlad eseje: http://alexthunder.livejournal.com/309815.html Už nějakou dobu přemýšlím, jak různým lidem vysvětlit, jak programátoři vlastně pracují. Lidem, kteří nepracují podobným způsobem. Co se děje v geekově mysli, když dlouhou dobu zírá na monitor a občas napíše pár znaků? Přijde mi těžké, téměř nemožné, něco takového vysvětlit v podstatě komukoliv. Vypadá to, jako by celá společnost byla rozdělena […]

Dobrodružství s Ask Toolbar

K nové verzi Javy nám Oracle nadělil dáreček v podobě univerzálního kurvítka webových stránek. Jmenuje se Ask Toolbar. Neobjevuje se bohužel jen jako součást instalace Javy, ale je v poslední době přibalován i k užitečným prográmkům zdarma.
