Motto.
Homo nascitur imperfectus, sed perfectibilis est cum virtutibus et scienciis.
Ad scienciam vero aquirendam duo principaliter sunt necessaria, scilicet karitas
seu dileccio et sedulitas sive continuacio. Magister Cristiannus de Prachaticz (Kříšťan z Prachatic) Algorismus prosaycus, prefacio, ante 1439 |

3.3 A few words about my surname
| Under construction. |
3.4 Web pages of members of our family and my relatives
| Here are some web pages of members of our family and my relatives: |
| My father Míla and his band named „Katastrofální předpoveď počasí“ (The catastrophical weather forecast). |
| My mother Bohu – the ceramicist; you can see also her e-shop (at Fler.cz) and buy a piece of ceramics ;) |
| My mother's husband – the joiner. |
| My brother Jakub – the photographer. |
| The business of my cousin Ondra. |
3.5 LaTeX
| Recently, I was an organizer of a small workshop at our university (you can see the web page of this workshop here). You can find below the book-of-abstracts, the workshop timetable, and the file with badges bellow; all done in LaTeX. You can download a LaTeX .sty file developed for easier conference timetable assembling (this .sty file implements among others the sexagenary arithmetic for authomated time computing; in the .zip file is an example of usage, too): |
| [ book of abstracts ], [ workshop timetable, (with a differently colored picture in the background here), and timetable.zip; not uploaded yet ], [ badges ], and [ proceedings ]. |
3.6 HTML
| For some reasons, once a time, I was generated a list of all SGML characters (it was done in MATLAB), you can find it here: [ SGML Characters ]. |
Guestbook (leave me a message here, if you want, ...)
