Magyarok a marson - Sebek nyalogatása
05/20/10
Lassan az élet kezd visszatérni a normál kerékvágásba.
Nekálltam rendberakni a marsjárót. Találtunk a tanszéken 1:200 áttételű fém fogaskereses DC motort, a végén enkóderrel. Ez lesz belecsuberákolva a cuccba valószínűleg. Lassab lesz, de gyilkosabb.
Sorra kerültek a megpukka -
Magyarok a marson
05/13/10
Ha egy mondatban kellene összefoglalnom a versenyt, akkor az EPIC FAIL jut eszembe.
A versenyre 14 óra tájékában érkeztem meg egyedül autóval. Budapest bűnös város. Mindenhol autó, nem lehet megállni térképet nézni. Ehhez hozzájön az, hogy minden második utca egyirányú. Természetesen nem -

A mai nap a készülődés jegyében telt.
Kaptam kölcsön "kempinglabortápot" akksit tölteni.
Ma lepróbáltuk élesben az autómata képleolvasót.
Sajnos nem működik kifogástalanul mivel a Logitech kamera autófókusza nem mindig jó helyre fókuszál. Most hekkelhetem az mjpgstreamert, -

Néha kellemesen lehet csalódni informatikus kollégákban is.
Vámos haverom 2 nap alatt összegányolta az automata képlelolvasót.
Én gyűrtem hozzá képleszedőt, meg fájlbaírós részt, így most boldogság van.
Átméreteztem a Virtualboxos lemezemet, ami Dotnettibor spanom szerint körülménye -

04/30/10
Néha az tud a legaggasztóbb lenni, ha semmi nem romlik el.
A buglista kiirtásra került, A missziót ma elpróbáltam legalább ötször. Vámos elvitte a virágot, hogy hétvégén gányol Labviewban valami képfeldolgozót hozzá. Kíváncsian várom.
Ma egyszer eltört a liftkábel, ezt a bugot zsug -

04/29/10
Ma megindult a tegnapi bugok kijavítása.
Ezen felül az alábbiak történtek:
- Az űrlift lemezeiből levágtam a felesleget.
- A lift kapott egy kapcsolót az orrára, ami megszakítja a mászást, ha felér a tetőre. Ez teszteléskor különösen hasznos.
- A mintavavő tányér rugós -

Ma elektró után nekiálltam tesztelni az előkészítőben a hétvégén elkészült megállásérzékelő modult a képfeldolgozóban. A dolog lényege mindössze annyi, hogy -
Napi Qt okosságok: vegyesválogatott

1) Amikor a QTimerek szórakoznak.
Történt a marsjáróvezérlő programmal, hogy elkezdett néha lefagyni a navigáció. Némi debug után arra jutottam, hogy bizony néhány QTimer nem emittál timeOut() szignált. Hosszas szívózás után rájöttem a dolog nyitjára. A program több saját készítésű könyvt -

Simplephpblog költöztetése ATW-re.
02/28/10
Ahogy most elnézem siker van.
Átmásoltam, átírtam az sql configot, és működött az ékezeteket leszámítva. Ennek az volt az oka, hogy az atw ISO-8859-2 kódolást használ, amit a header("Content-Type:text/html; Charset=UTF-8"); sem képes felülbírálni. Nincs más hátra, mint előre. < -

Egyszer véletlenül ráakadtam a batlabs oldalára. Itt volt egy modelszám kalkulátor, amibő
