-<strong><h1>XX. predvaja:</h1></strong><br>
-<p><strong><h2>Naloga na hitro:</h2></strong><br>
- Nastavi uro na strežniku s pomočjo rdate. Napiši program, ki pretvori 24-bitna števila z dvojiškim komplementom v decimalno obliko.</p>
-<p><strong><h2>Navodila:</h2></strong><br>
- 1. Iz imenika s slikami virtualnih računalnikov povlecite sliki Student.vdi(klient) in SimpleArbiter.vdi(strežnik).<br>
- 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte Student.vdi ter SimpleArbiter.vdi.<br>
- 3. Zaženite oba navidezna računalnika.<br>
- 4. Na Student se prijavite z uporabnikom <strong>root</strong> in geslom <strong>kaboom</strong> na SimpleArbiter pa z uporabnikom <strong>tester</strong> in geslom <strong>SedemKrogovPekla</strong>.</p>

-<p><h3><u><strong><em>Prvi del naloge: posodobi uro računalnika s pomočjo rdate.</em></strong></u></h3><br>
- 1. Preverite in si zapišite IP naslov na SimpleArbiter. (ifconfig)<br><img src="slike/bu2.png"><br><img src="slike/bu3.png"><br>
- 2. Z ukazom <strong>sudo apt-get install</strong> rdate namestimo program rdate.<br>
- 3. Na Student z pomočjo rdate posodobi uro računalnika. <strong>rdate IP_SIMPLE_ARBITER</strong><br><img src="slike/bu4.png"><br>
- Opozorilo: NI napaka, če se posodobljen čas ne ujema s pravilnim časom. <br>
- </p>

- <u><strong><em><h3>Drugi del naloge: napiši program, ki pretvori binarni zapis 32-bitnega števila v decimalnega.</h3></em></strong></u><br>
- Nalogo lahko rešite v Javi ali v Pythonu. Prav tako pa lahko kodo pišete v poljubnem tekstovnem urejevalniku.</p>
-<p><br>
- JAVA------<br>
- 1. Z ukazom nano bintodec3.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano<br>
- 2. Napišemo program za pretvarjanje 24-bitnega števila z dvojiškim komplementom v decimalno obliko<br>
-<img src="slike/bu6.png"><br><img src="slike/bu7.png"><br>
- 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.<br>
- 4. Če je še nimamo, naložimo Javo <strong>sudo apt-get install openjdk-6-jdk</strong><br><img src="slike/predvaja_clip_image003.gif"><br>
- 5. Prevedemo program <strong>javac bintodec3.java</strong><br>
- 6. Lahko ga še zaženemo ter preizkusimo <strong>java bintodec3</strong>. Na standardni vhod vnašamo 24-bitno število v šestnajstiški obliki<br><img src="slike/bu9.png"><br></p>
-<p>PYTHON------<br>
- 1. Z ukazom nano bintodec3.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano<br>
- 2. Napišemo program za pretvarjanje 24-bitnega števila z dvojiškim komplementom v decimalno obliko<br>
-<img src="slike/bu5.png"><br>
- 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.<br>
- 4. Program zaženemo z ukazom <strong>python bintodec3.py</strong><br><img src="slike/bu8.png"><br></p><br><br>

- <p>
- <h3> Testiranje </h3>
- 1. Lahko poženemo tester; z ukazom ./run_test.py<br>
- <img src="slike/s1.png"><br>
- 2. Kot "Upor. Ime" in "Geslo" napišite vaše podatke učilnice. (npr.: "pz1234@student.uni-lj.si" in "geslo123")<br>
- <img src="slike/s2.png"> <img src="slike/s3.png"> <br>
- 3. Kot ime naloge vpišite XX.predvaja.<br>
- 4. Ko vas program vpraša po poti programa vnesite vašo pot do programa za pretvarjanje. (npr.: če imate program bintodec3.py v isti mapi kot program run_test.py, vnesete: ./bintodec3.py)<br>
- 5. Povpraša tudi po IP naslovu SimpleArbiterja, vnesite.<br>
- 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo.</p>
