Po dlh\u0161om \u010dase op\u00e4\u0165 pln\u00e1 klubov\u0148a.<\/p>\n

<\/p>\n

Na ostatnom stretnut\u00ed ma milo prekvapila skuto\u010dne hojn\u00e1 \u00fa\u010das\u0165. Nazbieralo sa n\u00e1s a\u017e 8: FFG, Busy, \u010ci\u017eo, Ivan, Nairam, Ub880d, z00m a moja mali\u010dkos\u0165 – Ikon<\/p>\n

Tentokr\u00e1t som pri\u0161iel takmer na \u010das. Zdr\u017eal ma len semafor pri dosti\u017eke a auto som odparkoval o 9:32. Po vybrat\u00ed vec\u00ed z kufra, som na ceste v dia\u013eke zahliadol protiid\u00faceho FFG a pred samotn\u00e9 dvere klubovne sme dorazili takmer s\u00fa\u010dasne.<\/p>\n

\"DSCF1710\"<\/a>Vybalil som zop\u00e1r vec\u00ed a medzi nimi aj projektor – n\u00e1\u0161 staru\u010dk\u00fd laptop PIII s meotarom a od tejto chv\u00edle bolo pre m\u0148a toto stretnutie zna\u010dne ne-8-bitov\u00e9 a projektor sa mi stal takmer celodennou z\u00e1bavou. Do tejto aktivity som \u010dasom zatiahol aj nejak\u00fdch priaznivcov a odporcov Debianu, ktor\u00fd je prim\u00e1rnym OS na predmetnom kuse \u017eeleza. Odporcovia boli dokonca v niektor\u00fdch oh\u013eadoch h\u00fa\u017eevnatej\u0161\u00ed ako priaznivci a s pomocou oboch t\u00e1borov sa podarilo nakoniec uspokojivo rozchodi\u0165 v\u0161etky veci, ktor\u00e9 boli predt\u00fdm zna\u010dne probl\u00e9mov\u00e9 alebo nefungovali v\u00f4bec.
\nRozbeh\u00e1val sa hlavne X server na grafickej karte ATi Radeon M6 tak, aby podporoval plnoobrazovkov\u00e9 zobrazenie videa z TV karty. Po\u010das prest\u00e1vok, k\u00fdm bol X server zhoden\u00fd sme sa kochali sledovan\u00edm TV na farebnom ANSI termin\u00e1li s podporou libcaca (mplayer -vo caca).<\/p>\n

\"DSCF1723\"<\/a>\u010eal\u0161\u00edm orie\u0161kom bolo p\u00e1tranie po spr\u00e1vnom sp\u00fa\u0161\u0165an\u00ed skriptov preto\u017ee pri boote do runlevelu 2 sa laptop v\u017edy kusol. Preto bol sp\u00fa\u0161\u0165an\u00fd z grubu v recovery m\u00f3de a n\u00e1sledne sme ru\u010dne na\u0161tartovali d-bus a X-y.
\nNasledovalo vyrie\u0161enie sie\u0165ovania na viac ako jednu sie\u0165ov\u00fa kartu. P\u00f4vodne nain\u0161talovan\u00fd Wicd podporoval pripojenie iba k jednej sieti, ale \u201cpokrokov\u00fd\u201d projektor laptop m\u00e1 a\u017e 2 sie\u0165ov\u00e9 rozhrania – ehternet a WiFi. Prim\u00e1rnym rozhran\u00edm je WiFi, ktor\u00fdm ho prip\u00e1jame do netu. Na ethernet sme potrebovali pripoji\u0165 Raspberry Pi, na ktorom sa in\u0161talovali a aktualizovali v\u0161akovak\u00e9 softv\u00e9ry. Ve\u013ekej ob\u013eube sa napr\u00edklad te\u0161ila BruXyho housenka.sh<\/a> be\u017eiaca vzdialene v bashi na Rasp Pi.<\/p>\n

\"DSCF1713\"<\/a>\u010ci\u017eo vyv\u00edjal snahu nain\u0161talova\u0165 na Raspbiane ovl\u00e1da\u010de na DVB-T USB k\u013e\u00fa\u010d s Realtek chipsetom. Najprv tu\u0161\u00edm nefungoval github a nesk\u00f4r sa uk\u00e1zalo, \u017ee kompil\u00e1cia kernelu by zabrala cca. 7 hod\u00edn, tak\u017ee od tejto bohumilej \u010dinnosti upustil. Nosite\u013eom my\u0161lienky ovl\u00e1dnu\u0165 DVB-T na Rasp Pi bol prim\u00e1rne Ivan, ktor\u00fd pl\u00e1nuje vyu\u017ei\u0165 tak\u00fdto USB k\u013e\u00fa\u010dik ako \u0161irokop\u00e1smov\u00fd prij\u00edma\u010d, schopn\u00fd zachyti\u0165 napr\u00edklad sign\u00e1l lietadiel nach\u00e1dzaj\u00facich sa v pomerne \u0161irokom okol\u00ed ant\u00e9ny.
\n\u010eal\u0161ou aktivitou premietanou na projektore bolo Rasp PI tentokr\u00e1t s nabootovan\u00fdm RISC OS. Prizn\u00e1m sa, \u017ee mo\u017enosti tohto OS som sprvu podcenil, tak\u017ee som bol ve\u013emi milo prekvapen\u00fd mojou prvou sk\u00fasenos\u0165ou s n\u00edm. Svi\u017en\u00fd \u0161tart aj odozvy syst\u00e9mu s\u00fa nie\u010do od \u010doho som si pri prev\u00e1dzkovan\u00ed Linux distier na tejto platforme odvykol.
\nSk\u00fasili sme e\u0161te zabugovan\u00fd xbmc, kde trochu hnev\u00e1 jednak problematick\u00e9 ovl\u00e1danie bez my\u0161i a tie\u017e nespr\u00e1vne prep\u00ednanie skladieb v MP3 playliste.
\nBusyho uchv\u00e1til nahrubo ofr\u00e9zovan\u00fd chladi\u010d na mojom Rasp Pi a mysl\u00edm, \u017ee sa m\u00f4\u017eeme te\u0161i\u0165 na nieko\u013eko hust\u00fdch makrofotiek v jeho fotodokument\u00e1cii zo stretnutia.<\/p>\n

\"DSCF1711\"<\/a>\"DSCF1712\"<\/a>Nairam priniesol vn\u00fatornosti z 20\u201d LCD panelu, ktor\u00e9 mu zv\u00fd\u0161ili po v\u00fdmene modulu v jeho monitore. Zbe\u017ene sme si ich pozreli iba z vonku a bli\u017e\u0161\u00ed prieskum ich e\u0161te len \u010dak\u00e1.<\/p>\n

\"DSCF1718\"<\/a><\/p>\n

Pozornos\u0165 p\u00fatal aj v\u00fdvojov\u00fd kit s STM32 kit s pekn\u00fdm 2.4\u201d LCD s dotykovou obrazovkou, ktor\u00fd priniesol Ivan. Toto vyzer\u00e1 by\u0165 po PIC32 \u010fal\u0161ia n\u00e1dejn\u00e1 platforma na emul\u00e1ciu spektra bez pou\u017eitia OS.<\/p>\n

\"DSCF1715\"<\/a>FFG rozobral kameru ve\u013ekos\u0165i kreditky zna\u010dky Technika, v snahe zisti\u0165 \u010di by sa z nej nejako dal vytiahnu\u0165 sign\u00e1l na \u010fal\u0161ie spracovanie. Kamera u\u017e pred dekapot\u00e1\u017eou nesl\u00fa\u017eila svojmu p\u00f4vodn\u00e9mu \u00fa\u010delu, pre slab\u00fa ne\u0161tandardn\u00fa intern\u00fa bat\u00e9riu, ktor\u00e1 by sa \u0165a\u017eko nahradzovala a preto je to vhodn\u00e1 kandid\u00e1tka na bastlenie.<\/p>\n

\"DSCF1720\"<\/a><\/p>\n

Dostali sme sa tie\u017e na chv\u00ed\u013eu k porovn\u00e1vaniu Androidov\u00fdch tabletov. Ja som priniesol Ainol Novo 7 Paladin, FFG hne\u010f 2 – Yarvik s IPS displejom a noname \u010dinsky tablet z FocalPrice za 40EUR.<\/p>\n

\"DSCF1707\"<\/a>Ak si dobre pam\u00e4t\u00e1m, tak v klubovni boli predsa len k zahliadnutiu aj 8-bitov\u00e9 ma\u0161iny. \u0106i\u017eo mastil svoju oblig\u00e1tnu C=128 no a jedin\u00e9 Spectrum – gum\u00e1\u010dika – priniesol z00m.<\/p>\n

\"DSCF1716\"<\/a>Nesmela ch\u00fdba\u0165 ani Gama, tentoraz verzia 192k, na ktorej diagnostikoval jej \u00fadajn\u00e9 nefungovanie s disketovkou. Av\u0161ak prinesen\u00e1 D80 nevykazovala \u017eiadne zn\u00e1mky chybovosti a preto padlo podorzrenie na predmetn\u00fa D40, s ktorou majite\u013e Gamu prev\u00e1zdkuje. T\u00fa v\u0161ak z00m nemal so sebou a preto p\u00e1tranie bude pokra\u010dova\u0165 a\u017e ke\u010f ju majite\u013e doru\u010d\u00ed. Z00m dokonca na\u017ehavil letova\u010dku, ale do nosa mi z nej neudrel pach kolof\u00f3nie s c\u00ednom, ale topiaci sa plast z \u00fachytiek kl\u00e1vesnice Didaktiku Gama.
\nObed prebehol vo \u0161tovrici (Ub, z00m, \u010ci\u017eo a ja) v na\u0161ej zvy\u010dajnej \u00e1zijskej prev\u00e1dzke. Zvy\u0161ok ans\u00e1mblu povedal, \u017ee vydr\u017e\u00ed aj bez obeda a zostal diskutova\u0165 v klubovni.<\/p>\n

\"DSCF1717\"<\/a>
\nStretnutie sme rozpustili okolo \u0161iestej ve\u010der a po rozl\u00fa\u010den\u00ed pred vchodom do klubovne s pocitom pr\u00edjemne str\u00e1venej soboty sme sa rozutekali u\u017e\u00edva\u0165 zvy\u0161ok v\u00edkendu.<\/p>\n

Pl\u00e1ny na marec bud\u00fa ve\u013emi z\u00e1visl\u00e9 od \u010dasov\u00fdch mo\u017enost\u00ed (a priepustiek od na\u0161ich man\u017eeliek, prateliek, det\u00ed, rod\u00edn at\u010f.) preto\u017ee tie si \u0161etr\u00edme na hlavn\u00fa marcov\u00fa akciu – Forever 14<\/a>.<\/p>\n
