Hacker gathering 28-29 May - Ohrid, Macedonia
by Arangel Angov 07 Apr '11

07 Apr '11

Ahoy! I'm a friend of Marek Mamut err.. Mahut :) and I know some of you from this years CCC in Berlin. Marek told me that this would be the best way to contact you all. Anyway, I'm from Skopje, Macedonia and I'm a member of the Skopje Hacklab called KIKA. We're organizing a regional hacker unconference called NSND (meaning Nothing Will Happen). Basically it's a hacker gathering where most of the people from the hacker communities of ex-Yugoslavija have been gathering for some years now and it usually happens few times a year in a different country every time. The event is more like an unconference rather than a conference, it's very relaxed, the point is to meet the people, have fun and exchange experience and knowledge along the way. We usually make an agenda when we get there and go with that after wards. We already have people coming from Croatia, Serbia and Bulgaria so if anyone from your group is interested in coming I can provide you with more detailed information about how to get here, prices etc. There are airports in both Skopje (the capital) and Ohrid and transportation from Skopje to Ohrid is frequent and cheap. We choose Ohrid as a location since it's one of the nicest places in the country and the date, the end of May since it's just before the tourist season starts. Please let me know if you're interested in coming and how many days you are willing to stay so that I can make the necessary accommodation arrangements (the sooner the better). Feel free to ping me with any questions. Cheers! -- Арангел xmpp/mail ufo \o/ linux.net.mk http://blog.spodeli.org

Fwd: [edubrm] [GGHC] Great Global Hackerspace Documentary
by Pavel Ruzicka 06 Apr '11

06 Apr '11

ahoj, jak pravdepodobne velka cast z vas vi, mame svuj soutezici tym zastupujici nas v Great Global Hackerspace Challenge s projektem EduBRM [1]. Poradatele nyni nadhodili napad, ze z celeho deni kolem teto akce spravi dokument ktery se bude skladat z videoprispevku jednotlivych hackerspaces. Bylo by tedy super, pokud by se mezi nami nasel jeden nebo vic jedincu co se chytnou kamery (nejakou techniku mame) a zacali to trochu dokumentovat i formou hybajicich se obrazku. [1] http://brmlab.cz/project/edubrm Zdar a diky ruza -------- Original Message -------- Date: Tue, 5 Apr 2011 16:18:28 -0700 From: Mark Sanders <mark.sanders(a)agentsilverfox.com> To: hackerspacechallenge(a)agentsilverfox.com Hi there, So guys are getting a lot of attention. In a good way, of course. We've received some interest in filming a documentary of the competition. We're talking with a San Francisco film company who has ties with the Maker Faires. The company is a loose collective lead by the Director and Producer John Behrens. The only way we want to pursue this is if we can involve all the teams, and not just the people we fly out to the event in May. With that in mind would the teams who have shot video be willing to share that content to be included in film? We haven't thought through how the final form of this idea will live - we certainly don't want to create a commercial product on the backs of your hard work. This might be something that we create just to be shared with the participants of the event as a keep sake, it could be something that will promote future Maker Faires or be a charitable project where revenue, if any, can go back to the Hackerspaces. Like I say, we're not there yet. We just felt that this time in history is too important not to capture for the future. We're going to put some more ideas together and keep everyone in the loop on the mailing list. In the mean time I created an FTP account on our server for where interested teams can upload copies of their video. Ideally I'm sure the editors would appreciate raw footage to work with but that can tie up your bandwidth for days. I'll leave it to your judgement. We'll be monitoring the FTP account to make sure we're not hitting any caps from our provider. I'll send the username and passwords in separate emails. host: agentsilverfox.com <http://agentsilverfox.com> username: hackerspaces If you have any ideas, please let us know.

Hi! We are a French organisation especially active in new media art in Prague. We will have exhibition and event this week. We would be happy if you could come and have a look and if we could know more each others! I personnaly won't be in CZ at that time but there will be Pascal Silondi or Jakub Grosz for sure on Saturday evening who you could meet then. Good if you could stop by!

Participants can enter here and navigate in different Underground City 3D online environments that are accessible through a series of computers connected to the Internet; these environments were developed collaboratively during the last 10 months by Libat and Prague College. Users can discover different types of cells connected to the “Rhizome architecture” of the 3D Labin ex-coal mine tunnels recently reconstructed by P. Silondi and J. Grosz from laser measurements. It is a vision of the being projected in abstraction and in the architecture of messages and data structures. It is a 3D multimedia environment where one can question their identity when surrounded by digital autonomous agents and emerging visions of a contemporary network society and interactive digital cities. The UC3D environments are the products of deep interdisciplinary collaboration, and are inspired by Stefano Cavagnetto and Bruce Gahir papers about “The conception of the self in multiple cyber worlds” where they discuss many issues about personal identity and propose a model of the Self in Cyberspace based on the information theory, “The Code of Coal” or “Cellular Automata and the Game of Life” that focuses on algorithms and representation and “Morality and Artificial Agents in Cyberspace.” The platform, which will then be accessible online, will reach another dimension, and will become a free public artwork accessible from anywhere. Underground City proposes a specific approach to democracy also in the fact that people from the public can display their own messages perceivable by the other users; they can influence the 3D world system, not only by their presence, but also with their participation in becoming citizens of Underground City. Authors: Libat (FR), Prague College (CZ), Skutr (CZ), M2F Créations (FR), NxGraphics (FR) Lamparna for Underground Landscape Participants can enter and navigate through Underground city 3D environments developed collaboratively last months. It is an interactive audiovisual installation where users are immersed simultaneously in multiple 3D cyber underground worlds projected in parallel. This is an inside partitioned space, a sounding board for dissonances, fractures and wandering of beings immured in the contemporary digital exhibition. Equipped with a “Lamparna” (lantern) and a hammer increased by motion sensors, the new twenty-first century minor may initiate their descent into abyss. There they can explore a network of multimedia tunnels lined with pixelated shadows, virtual characters glued to frantic loops, mechanical rhythms and over-cadenced sounds, all inspired by past industrial revolutions. Still under pressure and near to explosion, the belly can, at any moment, let an imperceptible lethal information sheet escape. The installation offers the user a chance to increase their influence, and is given the opportunity by using a computer network, to interact simultaneously with the contents of several interconnected cyber tunnels. It is a schizophrenic installation-system; it is an organism sensitive to stimuli that can react however contradictory to their translation, proposing a non-linear and chaotic storytelling architecture that uses 3D gaming technologies for the network to integrate and manipulate videos, sounds or 3D objects, and it also allows the "free" exploration of the virtual “diptych” while multiplying viewpoints. "Lamparna for Underground Landscape” is an adaptation of Underground Landscape, the first interactive installation that was part of the European project "Underground City XXI." It was proposed by "Libat" and created originally in situ for the Gamerz # 5 Festival and “Lamparna” installation that was developed collectively during the last Underground City workshops by Libat and students of Prague College. Authors: Pascal (FR) and Marie Silondi (CZ), Jakub Grosz (CZ), Rajmond Berisha (Kosovo), NxGraphics (FR), Stefano Cavagnetto (I), Bruce Gahir (UK), Tihana Valent (HR), Yevgeniya Drovossekova (KZ) Production: Libat (FR), Prague College (CZ), M2F Créations (FR), NxGraphics (FR) Those works were supported by European Cultural Foundation (ECF) and the Culture program of the European Commission UC 3D/XXI Project Presentation You will discover in images all of the Underground City events, artwork and research made during the last two years including: Labin ex-coal mine; the 3D environments development process; “Triangular propaganda - site specific performance in the Army House of Culture” developed in collaboration with Jakub Kopecky and the “Skutr” theater group and presented in the city festival of Legnica, Poland; “Underground Landscape," the first interactive installation proposed by Libat for UCXXI, and created originally in situ during the Gamerz # 5 Festival, in Aix en Provence, France; the four workshops organised by Libat and Prague College in Prague for the development of Underground City 3D environments and the creation of mixed-media installations and performances; interactive installations results created collaboratively by artists, interdisciplinary researchers and students like “Lamparna” or “Neurons.” Authors: Libat (FR), Prague College (CZ), Skutr (CZ), M2F Créations (FR), NxGraphics (FR) Art Catalogue Underground City Art Catalogue will be launched and presented by Stefano Cavagnetto during the vernissage evening on 9th of April from 6pm. This work aims to collect in a form of an art catalogue most of the theoretical and practical work developed during the creation of a virtual 3D futuristic underground town [Interdisciplinary Internet platform Underground City XXI (UC XXI)] by Prague College and Libat researchers and artists. The Internet platform UC XXI, was imagined as a 3D multi-user environment shared and distributed on Internet consisting of interactive spaces and avatars. The catalogue is divided into three parts: 1. Theoretical developments connected to virtual spaces and avatars 2. Art gallery of the futuristic environment developed 3. Activities originated from the project. The first part focuses mostly on the conception of the self in virtual environments, on the development of virtual personality models using a Wittgensteinian approach and on some aspect of modular architecture and the concept of fractal city for the futuristic town. This initial part is fundamental to the foundations of cyberspace and hence the fractal city as it attempts to examine some of the fundamental questions relating to identity in cyberspace and virtual personality. The second part uses the art work produced using a modified version of the Unity game engine. The art work is presented in a form of art gallery of paintings which starts from the cloud points of the real coal mine and it goes to the final abstract and modular environment developed using fractal concepts such as self similarity and scalability. The third part of the catalogue refers to the multiple activities originated from the project, including workshops, exhibitions and special courses involving the schools of Art and Computing at Prague College Exhibition of Visual Identities developed by Graphic Design students The exhibition will present a selection of around 25 works by Prague College Graphic Design students done for the Underground City XXI project, for which they developed visual identities under the supervision of Graphic Design Programme Leader Simon Gray. Prague College Research Centre Bulletin Beginning in March 2010, the Prague College Research Centre Bulletin started to publish research. The Bulletin is a quarterly publication that publishes current and relevant research activities of lecturers and students at Prague College. This Bulletin forms an integral part of the Prague College Research Centre (PCRC) and provides a medium whereby the research activities of the centre can be documented. All Underground City 3D/XXI research, productions and activities have been analysed or published in the Prague College Research Bulletin. During the exhibition time, all articles will be accessible for reading.

Požičať nahrávacie zariadenie

Nemáte niekto zariadenie na nahrávanie zvuku, ktoré by ste mi mohli požičať na víkend 15-17.4.? Nahrávať budem ľudí, čo budú hrať na gitare v školskej triede. Môj nahrávací prístroj síce nahráva, ale je vhodný na prednášky, nie na hudbu (zatiaľ každá hudba bola naňho moc hlasná). Stevko

VyBRM, aneb Brmlab na vylete?
by George Blackhead 03 Apr '11

03 Apr '11

Ahoj Jaro uz je asi tady. Zacina to vsechno kvest a teplomer uz se se mnou taky bavi docela pratelsky... Myslim si ze je cas vyhnat geeky z jejich nory na poradnej vejlet... Takze hledam zajemce na nejaky stredne dlouhy Brm-vylet. Videl bych to asi jako poznavacku prazske prirody. Zacal bych prirodou Prahy 7,8,9. Tady to znam nejlip... ;-) ================================================ Plan mam nasledujici: -sraz v Brmlabu - nejslabsi natury tam rovnou zustanou -1. etapa = Vystaviste/Stromovka - ti opravdu slabi jedinci zustanou ve Stromovce -2. etapa = pres reku do Troje - slabosi nasednou na bus u ZOO -3. etapa = Trojou vzhuru k Bohnicim - dalsi moznost pro netrenovane jedince - z Bohnicich je dobre spojeni MHD -4. etapa = opidium na vyhlidce nad rekou -5. etapa = statek ve Starych Bohnicich/areal lecebny - pokud to nekdo nezvladne psychicky, tady ho zanechame -6. etapa = Cimickym lesem ke Kobylisske vozovne - zde uz mohou se cti odpadnout damy a individua slabsi povahy (ne, opravdu nejsem sovinista) -7. etapa = pres Dablicky les smer Dablice -8. etapa = smer Prosek - po ceste je mozno "legalne" vylet rozpustit, uz budeme mit v nohach cca 13 km a to je pro mnohe vic nez dost. Tedy je mozne to stocit k metru Ladvi a akci ukoncit. -9. etapa = pro otrlejsi jedince rad doplnim dalsi trasu: z Proseka pres prosecke skaly az k bobove draze a lanovemu centru v Podvinni. Celou akci bych asi zakoncil u metra Vysocanska, po cca 17km. http://mapy.cz/#mm=F@dm=133111040+135991552-13056+20736-8960+2560-7424+2048- 11264-1024-3840+10240+2816+2048-1024+8960-3840+768+1024+14080+256+7424+3840+ 5632-512+5120-6912+768+1792+11008-2560+1536+1280+3328-10240-512-6400+4352-28 16+7936-4608-256+4608+3584+8192+0+256+7936+4352+512+6144+9216+3072+3840+1536 +11008+5888-5120+6912-6656+11776-768+5376-1024+0-6400+3840-16128+4608+512+15 872+7936+9984+512+15616+8448+5888+1024+13824+2048+13056+7424+8960+8192+18176 +9728-2560-7168+3840-5632-1280-12800+5632-18944-7168-4864+6656-9216+2048-128 0+3840-5376+1280-1536-6912-5376-4864-5888-256-4096+8448-2048+256-2304+6400-2 560+6400+256+3072-5376-1536-4352+6912-5888+2048-7424+6912-2816+11520+3072@x= 133137152@y=136044288@z=12 Mam predstavu, ze to bude vylet na skoro cely den, i kdyz "ujit" se to da mnohem rychleji (3-4hod)... Sraz bych videl na 9-10 dopoledne, nekdy v sobotu, v nedeli... V pripade zajmu muzeme navstivit nejakou tu restauraci na obed, treba v Bohnicich je jich dost a i casove to bude vychazet mezi 12:00 - 14:00 do Bohnic. Pripadne se muzeme vyzbrojit jidlem na cestu a parkovat nikde nemusime... Konce trasy bychom dosahli nekdy v odpolednich hodinach. ------------------------------------------------------ Pokud mate zajem, hlaste se. Navrhuji sobotu, nebo nedeli, me je to jedno, vikend uz od pristiho tydne: 19.-20.3. 26.-27.3. 2.-3.4. Kdy mate cas a chut jit VY? ------------------------------------------------------ Ja osobne mam prochazky moc rad a skupinovou prochazku uz jsem dlouho neabsolvoval... Pokud se najde dost zajemcu, bude to myslim si prijemne straveny cas. O nekterych mistech na trase jsem schopen podat zakladni udaje, pripadne nejake zajimavosti, vetsinu tech mist znam docela dobre. Podle mne je to Brm-aktivita, na kterou muzete urcite pribrat i sve partnery, zejmena pro damy to bude urcite pritazlivejsi (ve vetsine pripadu), nez laborovani nad ethernetovym paketem, nebo integrovanym obvodem LM339. Nemluvim o tobe Chido... ;-) Myslim ze to je jedna z aktivit, kterou se zatim Brmlab nezabyval... Let's do outdoor-hacking! BH =================== P.S.: Pokud nekoho desi delka trasy, muze se odpojit po ceste, az bude mit dost. Pokud ma nekdo lepsi napad na vylet, necht se ozve. Ale pokud bude mit muj navrh uspech, budou i dalsi vylety, po Praze znam hodne peknych mist... (i v centru) BRM!

Osobne pro nej nemam pouziti, ale pripada mi skoda nechat ho tu lezet ladem, a domaci by patrne nijak nepotesilo kdyby ho musela recyklovat, takze jsem se chtel zeptat, naslo-li by se pro nej pouziti v Brmlabu?

Delat to cely rucne by IMHO byla sebevrazda, nebo prinejmensim by se z toho vytratila zabava. Ovsem ze zacatku musime zjistit limity RepRapu, takze jednoduche obvody (oscilator, klopny obvod, hradlo, mozna i scitacku) rucne navrhovat asi budeme.

Zdravim! Urcite ta radi uvidime v nasom hackerspace! Kludne sa mozme dohodnut aj na dlhsej prednaske mimo ramca Lightning Talkov, zavisi len od teba. Myslim, ze by to bolo vhodnejsie, kedze sa mi zda, ze tvoj zaber je o dost vacsi akoby sa dalo zhrnut do 5 minut. :-) Idealne je prist sa na nas pozriet v utorok (zhruba od 19:00 do neskoreho vecera), vtedy mame pritomnych najviac clenov (pravidelny meetup). Ak by bol zaujem o dlhsiu prednasku, tak je lepsie zrejme v iny den ako utorok (ten je dost hekticky). Detaily dopilujeme potom koncom dubna/zaciatkom kvetna. Na komunikaciu je potom lepsie zvolit obecny mailing list brmlab(a)brmlab.cz (v CC) aby sa do debaty mohlo zapojit co najviac clenov. Maj sa pekne! -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Sbirka na LEDky do ledbaru
by Petr Baudis 29 Mar '11

29 Mar '11

Ahoj! V projektu ledbar (http://brmlab.cz/project/ledbar; rada silnych RGB ledek, sviticich na chodnik vedouci podel brmlabu - skvela hracka na zaujmuti kolemjdoucich a zaujme snad i na ruznych brmlabich akcich) jsme dosli do faze, kdy mame pomerne finalizovane elektricke zapojeni i dobrou predstavu o konstrukci, proto prisel cas nakoupit LEDky samotne. Jedna LEDka stoji 150Kc, coz uz neni trivialni castka, proto potrebujeme Vasi pomoc s financovanim! :-) Libi-li se Vam projekt, prosime o prispeni! Staci se pripsat na wiki nebo mi poslat mail, a az mne uvidite, dat mi penize (LEDky uz jsem objednal). 13 LEDek uz jsme sesbirali na meetupu, na dalsich 11 musime jeste penize sehnat. Diky Vam, Petr "Pasky" Baudis

zadost o pomoc
by jens.retron＠seznam.cz 29 Mar '11

zdarbuh, Jak sem psal na fcb potreboval nych pomoc s timto napadem. Vec se ma tak ze sem prisel na to ue by se dal postavit pristroj na prenaseni emoci z cloveka na clovwka. Nechal se, se inspirovat eeg kdy se zobrazuje mozkova cinnost (radove od 0 do 40hz). Domnivam se ze by se toto dalo zaznamenat a prehrat. Zakladem sestavy jsou cidla umistena na hlave, ktera dokazou zaznamenat infrazvuk, nizkofrwkvencni zesilovac (nevim ale jak si poradit s vysokou mirou sumu, kterana twchto frwkvencich vznika) a pocitac s programem ktery dokaze tyto frwkvence zaznamenat (cili je potreba napsat program protoze bezne nahravaci programy pracuji az od cca. 30hz a vys) a stejnou cestou prehrat na jiinou osobu pomoci rezonatoru ( ve stejnym poctu jako cidla na uacatku sestavy) zaznam mozkove cinnosti prvniho cloveka. Myslim si ze na urcity vlnovy delce, pro presnem prezkoumani se nalezaji i konkretni pocity a tonemluvim o tom ze jdou pocity v podstate vytvorit. Takhle podobne funguje psychowalkman, kt ery dostava mozek do frekvencni hladiny alfa (tedy koncentrace)presto si myslim ze pri presne zvolene frekvenci lue lidsky mozek ovlivnit do te miry ze vyvola primo konkretni pocit. To je asi tak vse tak pro zacatk vse diky predem za odpoved jens

project "collisions"
by Florian Bittner 25 Mar '11

25 Mar '11

hi guys! when i was reading this thread in the morning i had mixed feelings in my stomach .. but not anymore. first of all i think that every space should pick their prroject as they like and implement it the way they think it should be done. secondly our projects are very similar but not exactly the same.. and the idea is simple and universal so its not a big surprise that our space is not the only one to come up with that. i do not want to discourage anyone in their projects and i dont want anyone else to claim who had which idea first, this is bound to cause drama and headaches.. i dont think we need this :) if everyone sticks to their original plans and implements what they came up with it will be very interesting and after 6 weeks we can compare our final implementations and maybe come up with another solution that integrates the best concepts of all the similar projects?! me personally i dont need to win a prize in this.. i think its a great chance to give the world a cool tool for education and get to know interesting guys with open minds all over the world. i wish you all the best and good luck! -overflo On 03/25/2011 08:38 AM, James Gray wrote: > Now stop that - at this rate, no one will do it. > > James > > > > > On Fri, Mar 25, 2011 at 12:37 AM, Mats Engstrom<mats.engstrom(a)gmail.com>wrote: > >> It seems like great minds think alike :-) >> >> Yesterday I was making a short list of possible projects for the >> Hackerspace in Kuala Lumpur and one of the projects was actually also a >> "edu-clicker" -like system. >> >> I suppose it can safely be removed from our list now then since two other >> spaces already might be doing a device like that. >> >> /mats >> >> >> On Fri, Mar 25, 2011 at 13:28, Tomislav Arnaudov<sargonout(a)gmail.com>wrote: >> >>> Hello >>> Personally I think that two similar projects is not bad idea >>> because we have many goals which can be achieved >>> simplicity , final prize and of course how project will be presented ... >>> >>> happy hacking >>> Sargon >>> Brmlab Hackerspace Prague >>> >>> >>> 2011/3/25 Ricky<rngadam(a)gmail.com> >>> >>>> Oh noees! >>>> >>>> I joined after you guys, posted in our blog the same idea as yours >>>> (EDUBUZZER; https://metalab.at/wiki/HSC2011 )! >>>> >>>> >>>> http://www.element-14.com/community/groups/xinchejian-gghc/blog/2011/03/25/… >>>> >>>> (although believe me, we actually came up with the idea two days ago >>>> and I have the email headers to prove it) >>>> >>>> Argh, now we have to find something else! >>>> >>> >>> >> >

net - checklist
by niekt0 25 Mar '11

25 Mar '11

Zdar, slubeny checklist: 1. Vyzdvihnut si moje karty na vratnici. 2. Zapojit kabel v brmlabe do switchu (pripadne nakrimpovat) 3. Stretnut sa s technikom z fpdco (cislo poslem) a chalanom z arachne (cisli poslem) 4. Pojdete do 3.patra, do "datoveho uzlu" 5. V jednom racku je bily gigbitovy switch z brmlabu, (hned nad switchom upc) ten vymenite za doneseny rackovy switch. 6. Pripojite do toho switcha: - brmlab - miestnost 205 - miestnost 104b - misetnost 112-10 7. tot fsio n.
