09 May '11

Ahoj, jak jsem avizoval vcera na IRC, dneska kolem 17:30 bych chtel udelat v Brmlabu mini-workshop na tema DIY Club-Mate. Nakoupil jsem 200g mate, 50g nejakyho specialniho mate mixu s chilli, kyselinu citronovou, pomerancovej tang, nealko pivo (chtel bych zkusit louhovat mate v pivu - pry to neni spatny), perlivou vodu a sirup z agave (to je ta rostlina, ze ktery se pali mezcal a tequilla). Zkusime ruzny typy ledovyho i horkyho mate a mozna si k tomu zahrajem i nejakou deskovku ;-) Jestli nekdo mate zkusenosti s mate, rad uvitam pomoc. Tesim se na videnou a pokud nekdo nemuzete, tak vezte, ze nejaky to ice mate bych chtel nechat i odlezet v lednici na ochytnavku na zitrejsi meetup. Zdar, Cestmir

ahojte, protoze se prubezne ucastnime a budeme ucastnit ruznych akci z nichz nektere budou jiste i outdoor (CCCamp treba) napadlo mne ze brmlabi logonapis na papirovem podklade neni uplne idealni a uzijeme totez i na materialu o dost trvanlivejsim. Jsem tedy za navrh investovat par stovek do vyroby "reklamni plachty". Zbeznym pohledem na ty INTernety jsem usoudil ze cena kolem 250Kc/m2 je cca normalni/dobra cena a lze objednavat i vyrobu jednotlivych kusu. [1] Protoze jsem nikdy vyrobu reklamni plachty nezadaval chci se zeptat zda tu neni nekdo v tomto zkusenejsi, kdo by mel uz nejakou firmu ozkousenou, na co si dat pozor (plachtoviny se jiste lisi kvalitou a gramazi) a vubec tuto investici prodiskutovat. Co se designu tyce predpokladam ze pouzijeme neco z /promote sekce na wiki. [1] http://sites.google.com/site/banerlevne/jak-na-to ruza -- e-mail: ruza(a)ruza.eu www: http://ruza.eu http://brmlab.cz

brmVPN

ahoj, fyi, pokud nekdo chcete vyuzivat remote access OpenVPN do brmlabu nasleduje popis jak si ji pro sebe zprovoznit. # na serveru data jako uzivatel root username=jsemtrouba # nastavim na svuj nick cd /etc/openvpn/easy-rsa/2.0/ source /etc/openvpn/easy-rsa/2.0/vars /etc/openvpn/easy-rsa/2.0/build-key ${username} # zkopirujete si k sobe do jednoho adresare # /etc/openvpn/keys/${username}.* # a /etc/openvpn/brmlab-client.ovpn # zeditujete u sebe v brmlab-client.ovpn cesty k "cert" a "key" # spustite vpn klienta sudo openvpn brmlab-client.ovpn # test pripojeni ping 192.168.77.24 # pokud chcete mit fukcni i DNS rezoluce pro sit CZFree.net # nastavte si 192.168.77.20 (brmko) jako DNS server OpenVPN je zprovoznena v modu tzv "split vpn", tedy bezny provoz do Internetu jde nezmenenym zpusobem pres vaseho ISP, konkretni IP rozsahy jsou routovane pres VPN do brmlabu (konkretne site .77 a .66, tj brmlab a warzone a kompletni rozsah czfree.net 10.0.0.0/8). Na problemy muzou narazit ti z vas kdoz pouzivaji stejne ip rozsahy i doma. Ti kdoz chteji pouzivat certifikat s passphrase pouzijte k vygenerovani klientskeho certifikatu skript /etc/openvpn/easy-rsa/2.0/build-key-pass Predokladam ze vetsina z vas je dostatecne schopna si na zaklade poskytnutych informaci zprovoznit vzdaleny pristup vlastnimi silami. Tem kteri maji se zprovoznenim problem, prokazatelne se pokusili si odstranit problem sami a nedari se jim, jsem ochoten poradit.

Kuchynka
by Petr Baudis 07 May '11

07 May '11

Ahoj! V kuchynce se nam zacali sirit potravinove moly, coz pri tech dlouhodobe otevrenych potravinach, co tam mame naskladane, neni zadneho divu, a neni to vec, ktere by se slo zbavit trivialne. Navrhuji tedy, aby si kazdy do meetupu odnesl, co chce zachovat, a zbytek se po meetupu zachoval. Take se nam zda se stale nedari zbavit spinaveho nadobi, ktere si po sobe nekteri nejsou schopni umyt. Jestli do meetupu napadne nekoho jine reseni, nez nadobi v brmlabu zrusit, dejte vedet... (Nebo alespon nadobi udelat pouze privatni skadovane v krabicich lidi, s tim ze s volne se povalujicim bude kdokoliv moci udelat cokoliv.) Petr "Pasky" Baudis

by Pavel Ruzicka 06 May '11

06 May '11

fyi, dnes jsem osobne mluvil s nasim dodavatelem ClubMate a pry zkousi zaridit ze by 0.3l i 0.5l lahve byly vratne. Zatim ale nemuze slibit ani ze to pujde ani kdy. Kdybyste vedeli o nekom kdo jezdi pravidelne do Nemec, tak by to realizaci pomohlo. Kazdopadne pro nas by to ted melo znamenat prestat lahve sypat do popelnice na sklo a vyhazovat je jen az je nebude kam dat. Detaily muzeme probrat treba na meetupu. ruza -- e-mail: ruza(a)ruza.eu www: http://ruza.eu http://brmlab.cz

The Learning Behind Gmail Priority Inbox
by Petr Baudis 06 May '11

06 May '11

Mel-li by nekdo zajem... (Pozn.: Predpokladam, ze pujde o pomerne odbornou prednasku.) ----- Forwarded message from Iveta.Mrazova(a)mff.cuni.cz ----- Vazeni studenti, dovolte mi, prosim, pozvat Vas na prednasku "The Learning Behind Gmail Priority Inbox," kterou proslovi Ondrej Pacovsky (Google Inc., Zurich, Switzerland) v pondeli, 16. 5. v 10.50 na MFF UK (poslucharna S9 v 1. patre budovy na Malostranskem namesti 25). Abstrakt prednasky je pripojen pod carou. Iveta Mrazova, KTIML MFF UK ================================================================== Abstrakt prednasky ´The Learning Behind Gmail Priority Inbox:´ Many Gmail users receive tens or hundreds of mails per day. The Priority Inbox attempts to alleviate such information overload by learning a per-user statistical model of importance, and ranking mail by how likely the user is to act on that mail. This is not a new problem, however to do this at scale, performing real-time ranking and near-online updating of millions of models per day signiﬁcantly complicates the problem. The challenges include inferring the importance of mail without explicit user labelling; ﬁnding learning methods that deal with non-stationary and noisy training data; constructing models that reduce training data requirements; storing and processing terabytes of per-user feature data; and ﬁnally, predicting in a distributed and fault tolerant way. While ideas were borrowed from the application of ML in Gmail spam detection, importance ranking is harder as users disagree on what is important, requiring a high degree of personalization. Because “importance” is highly personal, we try to predict it by learning a per-user statistical model, updated as frequently as possible. The result is one of the largest and most user facing applications of machine learning at Google. Ref.: http://research.google.com/pubs/archive/36955.pdf ----- End forwarded message ----- -- Petr "Pasky" Baudis UNIX is user friendly, it's just picky about who its friends are.

Food hacking base founded at CCC Summer Camp! (Please distribute widely!)
by Frantisek Apfelbeck 04 May '11

04 May '11

Greetings Everyone! We are very happy to announce the creation of a Foodhacking Base at the 2011 CCC Camp this August 10-14. The Foodhacking Base will be part of NeighborCamp, the village hosting the Hackers on a Plane trip. To feed the folks travelling with HoaP, we’ll have a well stocked and well equipped kitchen. Now to plan how we’re going to use it the “hacker way”! My role is to get cool people participating in this endeavour. So if you like cooking, fermenting, distilling or any one of a million things related to food and beverages, please get in touch! I'm already finishing the design of the kitchen and first list equipment list to have a basis for discussion. Once the show starts, I'm responsible for making sure everything goes nice and smooth and on budget. I'll be cooking and fermenting a lot, leading some of the shifts and workshops on every day basis. Your part? Be creative and think of something :-)) Otherwise come and join us, have fun, do some really cool food hacks, nice and simple (we are still missing the go go dancers for the party :-)) gender doesn't matter after twelve no one cares!). So here is the project wiki page and mailing list, sign for it, bookmark it or just pop in! https://www.noisebridge.net/wiki/Food_Hacking_Base_CCC_Summer_Camp_2011 http://lists.hackerspaces.org/mailman/listinfo/foodhacking See you all at CCC, Sincerely, Frantisek (Please distribute to any foodhacking or hackerspace lists you know of so we can get as many folk involved in planning as possible!) PS A bit more info. The deal is that we have a decent budget for equipment and ingredients. Our goal is to prepare food for the roughly 40 Hackers on a Plane (plus guests) at in the NeighborCamp village during the camp. In addition on 11th we will prepare party dinner for “whole camp”. There will be buffet style food at least three times per day, preferably 24/7, with plenty of vegans options all the time. That is what we get, that is what we give. I'm now opening the project to discussion, hopping that people will step up and we will be able to make this event really rock and roll. I'm enclosing a list of activities which I would love to see happening within the food hacking center, please do add what ever you would like to be doing and we will see what happens. I can imagine that we will split the day in shifts and there will be around 6-8 people on the shift, so we can take it easy and have a fun. I should mention that the Hacker on the Plane group is budgeting 10 EU per day per participant for food, so if you are eating with us you should consider contributing in cash or supplies. Nobody will be turned away, but please discuss alternative options with me in advance if money is an issue. I'll do my best to have some great free food and beverages for helpers, give me some time to negotiate there :-)) Have a great time and I hope to see many of you in the kitchen or at least popping in for some treat. Sincerely, Frantisek Algoldor Apfelbeck
