Mam dojem, ze jeden z tech lidi, o kterych se tady pise psal, ze se stavi v BRMLAbu a nikdo mu neodpovedel [mozna jsem moh ja, no]. Kazdopadne preposilam, treba nekoho zaujme, pripadne nejaka klicova slova tam jsou. S pozdravem a omluvou, ze ted nejsem moc brmactive, kdyz by mi nekdo neco chtel, tak prosim email, jedina forma komunikace na kterou ted reaguju jakestakes. ~ Over -------- Původní zpráva -------- Předmět: DARK WALLET: A RADICAL WAY TO BITCOIN Datum: Wed, 25 Sep 2013 09:56:29 +0200 Od: Eugen Leitl <eugen(a)leitl.org> Komu: tt(a)postbiota.org, cypherpunks(a)al-qaeda.net, info(a)postbiota.org, zs-p2p(a)zerostate.is "radical", huh. http://www.newyorker.com/online/blogs/currency/2013/09/dark-wallet-bitcoin.… DARK WALLET: A RADICAL WAY TO BITCOIN POSTED BY MICHAEL DEL CASTILLO Cody Wilson is a twenty-five-year-old former law student at the University of Texas at Austin. He is also the inventor of the Liberator, a gun made almost entirely from plastic pieces created with a 3-D printer; he also uploaded to the Internet a blueprint that anyone could use to print such a gun. Wilson, who espouses libertarian views, created the blueprint to make a point: information should be free. Not everyone agreed with him. In May, after Wilson successfully fired the gun at a range near Austin and posted the design online, the State Department requested that those files be removed from the Web site of his nonprofit, Defense Distributed. Wilson complied—but not before the files had been downloaded two hundred thousand times, igniting a debate about whether there should be limits to the free flow of information over the Internet, and over the role of the government in enforcing those restrictions. Wilson lives in “a utopian world in which contraband will be only a notional concept, because enforcement will require policing ideas and blueprints, not simply goods,” Jacob Silverman wrote in a piece about Wilson and the Liberator in May. A native of Cabot, Arkansas—a small suburb of Little Rock—Wilson said that the State Department’s action persuaded him to drop out of law school and pursue revolutionary activities full-time. In fact, he had been planning his next endeavor for a while. When Indiegogo, a crowdfunding site, booted Defense Distributed’s campaign in August, 2012, for violating its terms of service—Indiegogo said the project related to the sale of firearms; Wilson said it was for the creation of information—Wilson began to raise money by asking people to support him using a currency called Bitcoin: encrypted, difficult-to-trace bits of code that function like cash and can be exchanged over the Internet without a bank or a PayPal account. Wilson said that he eventually raised two hundred bitcoins for the Liberator—the equivalent of twenty-seven thousand dollars, according to the current exchange rate. His efforts attracted the attention of a twenty-five-year-old Brit named Amir Taaki, who e-mailed him with an invitation to speak at the Bitcoin 2012 Conference, in London. He accepted. Wilson and Taaki met in person for the first time in January of 2013, when Taaki took Wilson to visit a workspace for hackers is Bratislava, Slovakia, and to anarchist squats in London. They reconnected in Berlin that July and began hashing out a plan to use the as of yet unregulated, untaxed, nearly untraceable currency in a way that would, like the Liberator, undermine the ability of governments to regulate the activities of their citizens. In the Bitcoin world, where banks no longer serve as intermediaries between people and their money, bank accounts have been replaced by online “wallets” that people can use to virtually store and send bitcoins. Wilson and Taaki’s project, tentatively known as Dark Wallet, is a simple wallet designed to be easier to use for people who aren’t tech-savvy; they hope that in turn accelerates the currency’s rate of adoption around the world. The wallet will be open-source and free to use. Eventually, Wilson and Taaki hope to create a vast stable of Bitcoin-related tools. The goal, for Wilson, is similar to what he tried to do with the Liberator: use technology to remove government intervention from his life, and from the lives of like-minded people. Unlike many current Bitcoin wallets, which can be difficult to download and cumbersome to use, Wilson and Taaki are designing Dark Wallet, they told me, as an easy-to-install plug-in that sits discreetly on users’ Chrome or Firefox browsers. Made for Windows, Mac, and Linux computers, Dark Wallet would move most of the energy-sucking process of insuring there’s only one of each bitcoin in circulation, and that they aren’t spent in two places at the same time, to separate servers. Wilson still lives in Austin, working remotely on Dark Wallet with Taaki, who lives in an anarchist compound called Calafou, outside of Barcelona, and writes most of the code behind the wallet. Taaki and Vitalik Buterin, the co-founder of Bitcoin Magazine, a periodical covering the currency, are part of a Calafou-based organization called unSystem, which came up with the idea for the wallet; they’re working with a team of developers from around the world. Wilson, who will manage the development team behind Dark Wallet, making sure they meet their targets on time, is also producing a video and other material for a crowdfunding campaign to raise money for the project. Dark Wallet should be ready sometime in January or February of 2014, Taaki said, though he’s not committing to anything. “It’ll launch when it’s ready,” he said. And the details of an upcoming crowdfunding campaign have still yet to be solidified, though Taaki and Wilson expect it to launch sometime in October. The person or group that, in 2008, created Bitcoin—that is, released the protocol that defined what Bitcoin would be—called itself Satoshi Nakamoto. The online comments that Satoshi Nakamoto made before disappearing completely, in 2012, indicate that the creator of Bitcoin, like Wilson, was deeply mistrustful of economic institutions and designed the currency to be intentionally subversive. Bitcoin is created, or “mined,” as it’s called, by powerful computers that race to solve complex math problems and are rewarded for their work with the encrypted code that is a bitcoin. Today there are 11.7 million of the coins in existence, worth an estimated $1.6 billion, though their value fluctuates dramatically. Nakamoto set the number of coins entering circulation to halve every four years until 2140, when they will plateau at twenty-one million coins and never be produced again. Because no one can arbitrarily decide to print more bitcoins, and because no banks intermediate the storage and spending of the currency, the value of a bitcoin is determined by market demand. Wilson finds this very attractive. But where a currency exists, capitalism will inevitably find it. In recent months, Bitcoin has caught the attention of entrepreneurs, many funded by venture-capital firms, who have begun building Bitcoin-related start-ups. The companies include exchanges where people can trade bitcoins, along with services that let people store and spend the currency in places ranging from Amazon-style online markets to brick-and-mortar bars and restaurants. The mainstream entrepreneurs who are interested in Bitcoin have found a haven in a nonprofit called the Bitcoin Foundation. Writing about Bitcoin in April, Maria Bustillos described its executives as a “rational and sober group of adult administrators” who stand in contrast with the image of Bitcoin users as “wild-eyed kids camping out in half-deserted lofts.” Members of the foundation met in August with several federal agencies, including the Federal Reserve, the F.B.I., and the Secret Service. On the surface, the meeting was an educational exercise, meant to explain how Bitcoin works, but many observers assume it was a step toward regulating the currency. The foundation, which celebrates its first anniversary this month, calls itself an advocacy group “dedicated to serving the business, technology, government relations, and public affairs needs of the Bitcoin community.” One goal, according to Jon Matonis, its executive director of the Bitcoin Foundation, is to educate both public and private interests—including the government—about how the currency operates. (“The Foundation is not pro-regulation as some have claimed, but it is pro-education,” Matonis has written, adding that he supports “bitcoin education for legislative and regulatory entities” and that “lobbying on behalf of Bitcoin is not necessarily anti-market.”) Wilson, not surprisingly, sees working with the government as a betrayal of Bitcoin’s fundamental purpose. “The public faces of Bitcoin are acting as counter-revolutionaries,” he told me. “They’re actively working to try to diffuse it, and to pollute it.” He was referring, he said, not only to the Bitcoin Foundation but to venture capitalists and entrepreneurs in New York and Silicon Valley who increasingly embrace the currency as a way to profit, but don’t share his revolutionary aims. (Matonis said he is aware of Wilson’s concerns. “I don’t see my role as advancing crony capitalism,” he said.) Wilson believes Bitcoin should remain the backbone of a separate economy that undermines the government’s ability to collect taxes and to control the value of currency—not be subsumed into the mainstream economy. “The state is basically allowed because we have all chosen to use these certain institutions to channel our activity and commerce,” he told me. “But when we are enabled, through alternative means and technologies, to channel our commerce as we will, channel our production as we will, the state simply disappears.” Not everyone agrees, of course, that society would benefit from the disappearance of governments. Wilson used the Liberator to make the point that the government shouldn’t regulate the flow of information; he wants to use Bitcoin to help build an economy outside of the government’s reach. But his ideology, taken to its logical conclusion, would also leave services like roads, libraries, fire fighting, and policing in the hands of the private sector—whose interests may not be aligned, Wilson’s critics argue, with those of the public at large. Wilson knows that he could see blowback for his stance against the foundation: as a self-described “crypto-anarchist,” perhaps he shouldn’t be so concerned with who is or isn’t determining the currency’s future. And if the U.S. government attempts to regulate the currency, which seems likely, Wilson will also find himself once again in direct opposition to the government. Wilson and the suit-and-tie-wearing people at the Bitcoin Foundation share a common interest in bringing Bitcoin to as many people as possible. The foundation seems willing to play nicely with the establishment, and has been open to hearing about the interests of old-school players like venture capitalists and government regulators. Wilson, however, who was only recently firing an illicit gun into the desert, isn’t looking only for a new currency but for another way to liberate himself—and others—from government oversight. Michael del Castillo is the technology and innovation reporter at Upstart Business Journal, a member of American City Business Journals, which is a sister publication to Condé Nast. A graduate of Columbia University, he is also the cofounder of Literary Manhattan, a nonprofit dedicated to promoting Manhattan’s literary community and creating new ways to appreciate literature.

Whoop.de.doo se rozjíždí..!
by Anna Maresova 25 Sep '13

25 Sep '13

Vážení přátelé, už tomu budou dva roky co jsem vám představila Whoop.de.doo - sadu erotických pomůcek pro ženy a dívky. Její osud vypadal velmi příznivě. Sada získala několik ocenění i značnou pozornost v médiích, ale vize hotového produktu v té nejvyšší kvalitě se zdála zcela nereálná. Neustále jste se mě ptali, kde se dá Whoop.de.doo koupit. Bylo mi vždycky líto, že musím odpovědět: "Nikde to *zatím* nekoupíte, je to *zatím* jen návrh". Cítila jsem velkou zodpovědnost. Vůči vám, vůči všem, kteří mi celou dobu pomáhali a nakonec i vůči Whoop.de.doo samotnému. Vzala jsem to jako obrovskou výzvu a po ročních peripetiiích s investory jsem se a rozhodla jít vlastní cestou a se svými kolegy a podporou přátel jsem se pustila do intenzivní práce. Stejně jako mě lákalo prolomit tabu v oblasti erotických pomůcek, tak jsem chtěla vyzkoušet, jaké to je projít celým procesem od návrhu, přes výrobu až po prezentaci a distribuci celého produktu a ten si hýčkat. Pohlídat si každý krok, nedělat kompromisy (nebo co nejméně), zachovat nejvyšší kvalitu a hlavně původní návrh. Zkusit to bez manažerů, marketingových firem, distributorů a investorů. Neohlížet se na to jak se to dělá, nebo má dělat. Neohlížet se na "výhody" masové výroby v Číně, ale využít toho, co Česká Republika může v oblasti výroby nabídnout a také nejprve nabízet tam, kde se nápad zrodil. Dámy a pánové, je mi ctí vám oznámit, že Whoop.de.doo se v Podkrkonoší (Silroc.cz) právě rodí. Během měsíce a půl vám představím a nabídnu první produkt z celé sady - Whoop.de.doo Venušiny kuličky (mimochodem můj nejoblíbenější:). Navštivte právě spuštěné webové stránky: *www.whoopdedoo.cz*<http://www.whoopdedoo.cz/> * *a neostýchejte se poslat odkaz svým přátelům. Ti z vás, kteří chtějí sledovat průběh (no vlastně příběh) Whoop.de.doo a vědět o spuštění prodeje jako první, neváhejte se zaregistrovat. Děkuji za podporu a těším se někdy naviděnou!

Ahoj! Z foodhacking workshopu v brmlabu zustala rada surovin, napr. rasy, tempeh, kombucha atd.

Zejmena stale zijici veci asi neni dobre mit na autopilota, a aby nam v brmbaru ted rok lezely rasy mi taky neprijde optimalni. :) Diky, -- Petr "Pasky" Baudis If I had more time, I would have written you a shorter letter. -- Blaise Pascal

switch from doku to media wiki - yes or not, why?
by Frantisek Apfelbeck 18 Sep '13

18 Sep '13

Hi to all, I'm considering switching two doku wiki pages/portals for media wiki. I know some advantages of media wiki already I wonder now what are the disadvantages. One of these pages is my personal web page, so low traffic (less than 1000 access per month lets say) http://frantisekapfelbeck.org/doku.php second one is the Food Hacking Base (fhb) wiki https://foodhackingbase.org/ where it can get with upcoming 30c3 several thousands hits per month, so still nothing special (however with another crowd sourcing campaign you never know, in Google if you type “food hacking”, we are (food hacking base (fhb)) twice in first ten results of the search - on different portals than our homepage however. I have been warned that media wiki is harder to back up and I’m not sure about the install and updates (I’m weak on that but I can learn if I have to - have to sooner or later). After nearly a year with doku wiki I’m still not happy with the “looks” of what I’m doing there. To my experience it is so much more easy and quick to get a decent page in media wiki than in doku, that is the major reason for me to switch. Anyway I’m now reading more online about the media and doku wiki also checking where do we host our doku wiki and what are our rules/rights on the servers there. Many thanks for any info, I think that within next 10-14 days I should know what the fhb group thinks and I would proceed further depending on that, Sincerely, FAA PS Even if I learn how to install and admin the media wiki properly, I will be not around quite often to do that, even after settling down I travel quite a bit and when I’m on some international hacker event I can not really take care about some issues or updates etc. so I will need some reliable person to take the burden of admin work anyway and I do wonder how much more difficult it is under media wiki compared to doku wiki.

dotaz ohledne upgrade pocitace, co ma cenu a co ne

Podivat se na video, je high definition na to moc? Jinak klasicka kancelarska a surfing prace, blogi, free office atd, rad bych mel otevreno par oken najednou aniz by to bylo priliz pomale. Hry nikoli. Do nekolika mesicu bych mel byt schopen pres budget zakoupit novy stroj, takze tohle je pro me vyuziti prozatimni zalezitost, pak by to zrejme uzivala hlavne ma pritelkyne stale na vyse zminene aktivity. Mel bych podotknout, ze mam v supliku dalsi 250 Gb harddisk, ktery doufam, ze nejak pripojim, dohromady mi takova storage kapacita bude na dlasich pul roku ci tak bohate stacit. Je tam samostatna graficka karta, kterou jsem zatim v ls hw neodhalil, vam se to jiste podari, je dobra? V tuhle chvili mi prijde rozumne zakoupit dalsi 2 ci 2x 2 Gb operacni pameti, nejsem si jeste jist co je nejlepsi pomer cena vykon, jak vyte, ziji v Korei na ostrove, takze to bude tak jako tak pres Internet ... Mejte se prima a dik za jekokoliv info. Ahoj Frantisek PS Hlavni operacni system je Linux Mint 14, jako druhy v dual boot zvazuji Windows 7, myslite, ze to stroj zvladne ve sviznosti?

[ Bubenská 1 natáčení seriálu "Clona" 16.5. a velkofilmu "Child44" 19.5.]
by Petr Baudis 12 Sep '13

12 Sep '13

----- Forwarded message from Jiří Boch ----- Dobrý den všem, Rádi bychom Vás jako uživatele budovy Bubenská 1 informovali, že: V pondělí 16.5. proběhne natáčení seriálu ČT "Clona" na vedlejším jižním schodišti (blíže řece) mezi přízemím a prvním patrem (centrální velké schodiště nebude dotčeno) a především na dvoře jih (zásobovací) od 10 do 18 hodin spojené s omezením až nemožností vjet na tento dvůr. Nízký rozpočet u této akce, tak by to měla být lehká kavalerie méně rozprostřená do okolí budovy a brzkým koncem po zdařených záběrech. Ve čtvrtek 19.9. je plánováno krátké natáčení ve čtvrtém patře atria centrální budovy. Jedná se o velkofilm "Child44" o masovém vrahovi Čikitalovi, který snědl až 44 dětí http://criminalminds.wikia.com/wiki/Andrei_Chikatilo . Akce je spojena s celodenním záborem komunikací téměř kolem celé budovy včetně dvoru a čelního parkoviště napojeného na Bubenskou ulici, vše pro parkování obsluhy filmu. Poprosíme o zvážení Vašeho alternativního parkování a vůbec střídmé použití Vašich vozidel v tento den s ohledem na velmi omezené parkování v okolí budovy a nemožností vjezdu do budovy. Omlováme se za omezení plného využití místně dotčených prostor a případné krátkodobé přerušení průchodu. Vlastní natáčení uvnitř budovy by mělo propběhnout vždy odpoledne v rozsahu maximálně dvou hodin s častými pauzami a krátkým snímáním. Děkujeme Vám za pochopení s pozdravy Jiří Boch za správu objektu Bubenská 1 ----- End forwarded message -----

Ahoj pokrocil jsem se svoji fotochemickou 3D tiskarnou k realnym pokusum a narazil na celou radu problemu se stavajicim softwarem. Vzhledem k tomu ze ten soft psal neprogramator tak ackoli se dostal velmi daleko tak diky absenci programatorskych navyku atd.. no proste je treba zacit od nuly. Timto bych rad oslovil nejakeho dobrovolnika ktery by se rad podilel na vyvoji tiskarny jako programator. co mohu nabidnout na oplatku? zapujcit prototyp tiskarny pro vyvoj sw a nasledne experimenty pomoc brmlabu vyrobit vlastni stroj, zrejme bych dokazal sehnat celou radu komponent zdarma netreba podotykat ze lze tisknout po vrstvach napriklad i 0.005mm tlustych a rozliseni xy je zavisle na rozliseni projektoru ale typicky 0.1mm zadani software: jedna se o software pro velmi podobny system tisku jako je na nasledujicim videu: http://www.youtube.com/watch?v=snOErpOP5Xk muze to byt napsane v cemkoli co je pro to idealni predpokladam ze se bude jednat o opensource predpokladam beh primarne na linuxu fajn by byla i rozumna portovatelnost na widle zasadni funkce jsou zvyraznene vykricnikem gui/tui ovladani tiskarny: referencni pohyb (nulovy bod stroje) !rychly, pomaly pohyb ovladany z gui !pohyb po vrstve pripadne po poctu vrstev !nastaveni zakladnich pracovnich parametru jako je expozice vyska vrstvy !ukladani parametru do configu !start od zacatku !start od libovolne vrstvy (pokracovani v predchozim tisku) !moznost prubezne menit parametry (stopnout tisk zmenit napr. dobu expozice a pokracovat) mozna zobrazovat nejakou vzdalenost ode dna vanicky pripadne nuly stroje a kolikatou vrstvu tisknem tlacitko kontrolni odjezd (odjede pro nahlednuti stavu (cc +10cm nebo az nahoru) a pak se vrati zpet na polohu) nulovy bod tisku (dno vanicky) vztazeny k nulovemu bodu stroje v budoucnu vitana moznost pustit z commandline i neinteraktivne program muze byt pouze konzolovy, gr. vystup napr prez FB ale to uz by se patrne tlouklo s tema widlema vystup pro projektor: !na druhem monitoru je trvale projektor !po spusteni stroje defaultne fullscreen s cernou/cervenou obrazovkou, mozna se tam bude muset neco dit v neviditelnem spektru pro pryskyrici protoze nektere projektory jsou moc chytre !pro kazdou expozici zobrazi patricnej obrazek (asi PNG, vstupem je adresar se stovkami cislovanych png ) !zadne jine ovladaci prvky asi nejaka prace s rozlisenim mozna jen kontrola spravneho nastaveni (napr v mem pripade 1280x800) predchazet problemy s pomerem stran kruznice je elipsa atp... pocita se s pngcky ve spravnem rozliseni vystup pro mechaniku: !vystup pomoci RS232 pro interpolator GVE84 v budoucnu pripadne uplne jiny hardware !rizeni jen jedne osy !nejjednodussi je mit vsechny pohyby relativni, v lepsim pripade absolutni vzhledem k nule stroje datasheet: http://www.gravos.cz/download/doc/gve84_datasheet-full.pdf !po kazdem pohybu se dotazat jestli uz to dojelo, pote umoznit dalsi akce !moznost nastaveni mechaniky prevodu 1mm=xx impulzu, akcelerace a nekolika ruznych pracovnich rychlosti jine na odtrhavani jine na nejake rucni prejezdy jine na ponoreni referencni pohyb, cteni aktualni polohy z interpolatoru !moznost predcasneho zastaveni pohybu proces tisku: !prvotni 4 expozice jsou delsi (parametr z configu napr 400%) vsechny ostatni jsou pak stejne !zacina se s platformou u dna vanicky 1 vrstvu vzdalenou !exponuje se obrazek po nastavenou dobu !nasleduje zatemeni a nastavena pauza 1 (dotvrzeni pryskyrice) !odjezd ode dna na vzdalenost 1, rychlost 1 (probehne odtrzeni ode dna) !prijezd zpet - jedna vrstva, pauza 2 (vytlaceni pryskyrice mezi dnem a platformou/modelem) !exponuje se dalsi obrazek atd... dalsi vlastnosti budeme muset doplnit na zaklade nejake debaty v uplnem zacatku by asi vystacilo to promitani sekvence obrazku a pohyby, parametry jen z commandline/configu moznost startu od xte vrstvy dle parametru jako vyvojove minimum - stelovani platformy lze udelat prez silu nebo pri vypnutem budici motoru

Mixer pripojeny pres firewire
by Petr Baudis 11 Sep '13

11 Sep '13

Ahoj! Poridil jsem firewire kabel a pripojil jsem s nim mixak k brmvidu; na brmvidu jsem nainstaloval par balicku s "ffado" ve jmene. Pokud se na mixaku zmackne tlacitko s popiskem "firewire" a spusti se na brmvidu ffado-test-streaming -t 1 ozve se ton. Teoreticky bychom mohli z brmvidu hrat pres firewire nebo delat jine triky, moje puvodni motivace byla mit moznost softwarove ovladat mixak samotny. Nevypada to ale zcela primocare (typu alsa mixer nebo hejblatka ve ffado-mixer) a nemam cas si s tim dal hrat, chcete-li se na to nekdo mrknout, smele do toho. :) Happy hacking, -- Petr "Pasky" Baudis If I had more time, I would have written you a shorter letter. -- Blaise Pascal

Jak postavit zdroj 90V 400mA constant current (na elektroforezu)?
by Petr Baudis 11 Sep '13

11 Sep '13

Ahoj brmlabaci! Rad bych Vas poprosil o radu, jak na konstrukci zdroje 90V 400mA constant current (tedy bude-li zatez menit odpor, nebude se protekajici proud menit). S mymi znalostmi si umim predstavit tak transformator 220->90V a za nim diodovy mustek + kondenzator (predstavuji si, ze to by jako 90V DC mohlo stacit), nevim ale, jak: (i) Zaridit to proudove omezeni na 400mA. Asi staci presnost +-10% a nemusi to byt kdovijak energeticky efektivni, prednost ma konstrukcni jednoduchost. Nasel jsem na netu ruzna zapojeni, ktera si umim predstavit treba na 5V zdroji, u 90V zdroje jsem si ale podstatne mene jisty. Co byste doporucili? (ii) Dimenzovat zarizeni s ohledem na vykon; nevim, jestli je 36W hodne nebo malo, u kterych soucastek (civky? diody?) si dat pozor a jak to resit. Diky za kazdou radu, -- Petr "Pasky" Baudis If I had more time, I would have written you a shorter letter. -- Blaise Pascal
