img class=face src=http://planet.ubuntu.com/heads/Bodhi.Zazen.png alt= pThis blog is at the request of some Ubuntu users and describes how to restrict users access to applications and/or system files with rbash./p prbash is a #8220;restricted shell#8221; and can be helpful in restricting users. This can be used, for example, to allow limited ssh access in order for a user to perform specific tasks, yet keep the user away from system files and applicatoins./p psee  : a href=http://man.he.net/man1/rbashrbash features / restrictions/a/p pBut rbash needs to be #8220;hardened#8221;./p pStep 1: Install rbash :/p prbash is not #8220;installed#8221;, it is a symbolic link to bash. rbash is present by default in Ubuntu but not Fedora (or Centos) for example./p pFirst, add a user to your system, here I will call the user #8220;ruser#8221;. You may use the gui tools or the command line to add this user. Then, if needed #8220;install#8221; rbash and set the users shell to rbash./p p class=codesudo ln -s /bin/bash /bin/rbashbr / sudo bash -c #8216;echo #8220;/bin/rbash#8221; gt; /etc/shells#8217;br / sudo chsh -s /bin/rbash ruser/p pStep 2: Harden rbash/p pNow we need to harden the home directory a bit./p pFirst, lets change ownership and permissions of ruser#8217;s home/p p class=codesudo chown root.ruser /home/ruserbr / sudo chomod 750 /home/ruser/p pNow let us lock down  rbash a bit. The #8220;critical#8221; files and environmental variables are PATH, .bash_login, .bashrc, .profile, .bash_profile, .bashrc, and .bash_logout./p pAs root (sudo -i or su -)/p p class=codecd ~ruserbr / rm -rf .bash_login .bashrc .profile .bash_profile .bash_logoutbr / touch .bashrcbr / echo #8220;. .bashrc#8221; gt; {.bash_login,.bashrc,.profile,.bash_profile,.bash_logout}br / echo #8220;export PATH=#8217;/home/rbash/usr/bin#8217;br / mkdir -p /home/ruser/usr/binbr / chown -R root.ruser .bash* .profile /home/ruserbr / chmod 640 .bash* .profilebr / chmod -R 750 usr/bin/p pDepending on your preference you may wish to lock down additional configuration (. or dot) files as well, such as .vimrc or .nanorc/p pNow, review the contents of the home directory :/p p class=codels -la ~ruser/p pStep 3: Add access (links) to applications./p pWe now have a fairly restricted #8220;base#8221;. To add applications to rusers path, use a link :/p pAgain, as root,/p p class=codeln -s /usr/bin/vim /home/ruser/usr/bin/vim/p pIf you need this use to be able to do a task as root, this is where sudo shines. Add the user to visudo and add the command(s) allowed to run as root. You still need to make a link from the command to /home/ruser/usr/bin ./p pFor remote access, I also advise you use keys, which will allow you to not only increase security for our ssh server, but also restrict users from potentially undesirable actions (running commands, binding ports). See my previous a href=http://blog.bodhizazen.net/?p=6svn+ssh/a blog for some hints on how to lock down your ssh keys./p pTake care to remain diligent, as with all things, there are ways to break out of a rbash shell. This set up can be enhanced further by setting up the user in a chroot jail./p pSee also : a href=http://man.he.net/man1/rbashman rbash/a/p

Author : Glenn Blakeslee

He became part of the Grand Flyby Mission midway through the third decade of his life, as a junior designer on the Flight Data Subsystem team.

He found himself at the leading edge of spacecraft design, and worked with the members of his team to build a robust device capable of data-handling functions for a long-term project.

He went to the Cape for the liftoff, was amazed to see the spacecraft climb on a column of flame. He met a girl on a Florida beach, and a year later married her.

The next years were heady times, as the spacecraft arrowed its way to the outer planets: Jupiter and her moons were imaged, and Saturn and her rings fell to the instruments aboard the spacecraft. He lived as fast as the data coming in, speeding the crowding freeways of LA in his sports car and drinking more than usual. He had an affair, which his wife did not discover.

The spacecraft’s mission was extended, and he found himself no longer a junior engineer but in charge of a team. The FDS was his baby, he the hands-down expert. The spacecraft was the first to perform a flyby of Uranus, and the first to photograph Neptune.

In the fifth decade of his life, he found himself settling down. His fast car had long ago been traded for a family-style sedan. He spent hours at work designing methods for upgrading the spacecraft, and when he and his team succeeded the job of the spacecraft changed again, to a long-duration interstellar mission. His wife learned of his dalliance a decade earlier and, bored and facing an empty nest, divorced him.

Some of the instruments on the spacecraft —those with no use in the sparser stretches of the solar system— were shut down, and though the incoming data never ceased it did slow. He found his staff reduced, which was expected. He found his life had settled into a slow rhythm —collecting data from the far-off spacecraft, sending updates across the expanse, sleeping and eating.

One year after the spacecraft crossed the termination shock —the inexorable slowing of the solar wind— he suffered a heart attack. He took time off but kept charge of his small team. With doctors orders he was back on the job, but charged with shutting down two more of the spacecraft’s systems. Three years later he retired.

He kept a firm hand on the spacecraft’s systems as a part-time consultant. With only two instruments still collecting data, the mission had collapsed to a terminal phase. They held a party when the spacecraft entered heliopause, and it reminded him of the good old days, when the spacecraft was running fast through the outer planets and the data stream held discovery after discovery. Now past the edge of the solar system, the spacecraft would coast quietly forever.

It became apparent to him that he and the spacecraft had led parallel lives, from a fast and fiery launch to a slow cold end.

Late in his eighth decade he found that his time in the sun had created a defect in his skin which, in the darkness and solitude of his late age, would probably end his life. So, too, the spacecraft: its time in the sun had ended, the reactors that powered it all but discharged. But it sped on, and so might he.

The rapid telemetry of his heart would slow, the data stream of his brain would trickle to a stop —but he knew, somehow, that he and the spacecraft would ride together, into the light of lesser suns.

FQM once again brings us the latest episode of The Universe, ive watched a few episodes of it and loved it and this one has a pretty interesting title name . The beginning of history starts here. There are 50 billion galaxies in the universe. 95% is still uncharted. This series examines the mysteries of everything, from black holes to how our sun functions. Is our planet as insignificant to the cosmos as a drop of water is to the ocean? This series will investigate the uncharted frontiers of space and explore the possible existence of life-supporting worlds beyond our own.

As man moves to colonize the cosmos, the realities of sexual relationships and reproduction need to be addressed. Probe the physiological, psychological and cultural challenges of sex in space. From the sex act
through birth, look at how the extreme environments of space exploration might effect copulation, conception and developing human tissues, as well as how issues around sex might impact the emotional lives of astronauts. Get to the bottom of the rumors to find out if space sex has already happened, and look at how the burgeoning space tourism business may soon lead to a boom in space sex.

Parceque son Packard Bell montre des signes de fatigues, ma Loulloute a décider d'investir dans une nouvelle machine. Très attirée par les netbooks pour leurs faible coût et leur encombrement réduit, elle veux tout de même garder Ubuntu... Elle a donc choisi un Asus EeePc 1000H : un écran de 10 pouces, un disque dur bien fourni et une autonomie d'environ 4h... Je vais détailler ici la procédure d'installation de notre distribution préférée version 8.10 sur cette petite machine

Création d'une carte SD Bootable

Cette machine est dépourvue de lecteur optique, et je n'ai pas mon graveur externe sous la main... Qu'a cela ne tienne, ce PC est doté en standard d'un lecteur de carte SD, et j'en ai justement une sous la main. A partir de mon macbook (lui aussi sous Ubuntu Intrepid Ibex) et grâce au créateur de clef USB bootable intégré au système (menu Système > Administration > Create an USB Startup disk).

Il faut tout de même disposer d'une image CD de la version d'Ubuntu que nous voulons installer sur notre EeePC. On lance le créateur de clé Bootable, saisissons notre mot de passe et cette fenêtre apparait à l'écran :

• Cliquons sur other pour choisir l'images disque que nous voulons transférer sur la carte.
• Vérifions bien que le media destination soit bien notre carte SD (ou notre clé USB).
• Choisissons "Discarded..." pour ne pas créer d'espace de stockage pour un utilisateur sur la carte.
• Validons le tout en cliquant sur "Make Startup Disk"

Attendons cinq bonnes minutes, le temps que le programme finisse notre carte SD bootable...

Installation d'Intrepid Ibex sur notre EeePC

Il suffit de mettre notre carte SD dans le logement prévu à cet effet sur la tranche droite; de la machine, démarrons la machine et appuyons de suite sur F2 pour rentrer dans le bios afin de choisir le lecteur de carte SD comme périphérique de boot.

Nous pouvons alors commencer l'installation normalement. Personnellement, j'ai choisi de diviser mon disque en 3 partitions :

• Une particion racine de 10 Go
• Une partition "swap" de 1,5 Go
• Le reste pour la partition /home

Installation du noyau optimisé

Une fois Ubuntu installé, beaucoup de choses ne fonctionnent pas : le wifi, les touches spéciales, la gestion avancée de l'énergie. Il existe un noyau spécialement conçu pour les EeePc, il est disponible sur le dépôt array.org. Nous allons les rajouter, ouvrons un terminal, puis commençons par télécharger en tapant dans notre terminal :

wget http://www.array.org/ubuntu/array-intrepid.list

ajoutons ce dépot à notre liste :

sudo mv -v array-intrepid.list /etc/apt/sources.list.d/

Il nous faut enfin récupérer la clé d'authentification du dépôt array :

wget http://www.array.org/ubuntu/array-apt-key.asc

Puis :

sudo apt-key add array-apt-key.asc

Pour finir, mettons à jour la liste des paquets disponible grâce à la commande :

sudo apt-get update

Nous somme maintenant prêt à installer le noyau eeepc.

sudo apt-get install linux-eeepc

Une fois l'installation terminée, il faut enlever le noyau "generic" qui ne nous sert plus à rien :

sudo apt-get remove linux-.*-generic

La désinstallation terminée, nous pouvons redémarrer notre EeePC...

Tout ne fonctionne pas encore : il nous faut eee-control

Une fois le pc redémarré, le wifi fonctionne ainsi quue les touches de volume et de luminosité. Mais celles pour activer/désactivé wifi, de fonction (en haut à gauche au dessus du clavier) restent inopérantes, et le ventilateur à tendance à s'emballer légèrement. Toujours sur le dépôt array.org, il existe un petit utilitaire nommé eee-control. Pour l'installer, rien de plus simple, ouvrons un terminal (oui, toujours et encore...) et entrons la commande suivant :

sudo apt-get install eee-control

Une fois le paquet installé, il faut lancer l'applet eee-control-tray au démarrage de notre session gnome. Il suffit pour ça d'aller dans le menu Système > Préférence > Session Dans la fenêtre qui apparaît, cliquons sur le bouton Ajouter :

• Dans nom, mettons par exemple Gestion Eepc
• Dans commande, il faut mettre eee-control-tray
• Dand commentaire, mettons par exemple Applet de gestion EeePc

Redémarrons la session avec Ctrl+Alt+Retour Arrière pour que les changements soient effectifs. Une icône Eee à côté de celle du Network Manager (sur la barre du haut à droite). Maintenant, la combinaison fn+F2 désactive le wifi...

Un clic gauche sur cette icône permet d'activer la camera, le bluetooth, le wifi ou le lecteur de carte DS. Un clic droit permet de la paramétrer(définir les touches personnalisée, etc... ), d'avoir accès à la température du processeur et la vitesse du ventilateur.

Régler eee-control

Nous allons maintenant paramétrer plus finement notre applet : gérer les 4 touches raccourcis en haut gauche du clavier, être averti lorsque l'on active le wifi, le bluetooth... Cliquons avec le bouton droit sur l'icône Eee puis Préférence :

• Dans les zones Fn-F7/Fn-F8/Fn-F9, choisissons des actions attaché à ces combinaisons de touches. Nous pouvons choisir des actions déjà établies (toggle-bluetooth, toogle-camera...) ou mettre le nom d'une commande à effectuer (gnome-system-monitor ou firefox par exemple).
• Les zones Hotkey 1/Hotkey 2/Hotkey 3/Hotkey 4 correspondent aux 4 touches en haut à gauche du clavier, elle se paramètrent comme ci-dessus.
• Notification permet d'activer les avertissement d'activation/désactivation pour les éléments sélectionnés/
• Set Performance to powersave on battery n'a pas l'air fonctionnel sur le EeePc 1000h.
• Smart Fan Control permet de résoudre le problème du ventilateur qui ne s'arrête pas.

Voir le verrouillage maguscule

Petit défaut de notre EeePC : il n'y a pas de témoin lumineux pour le verrouillage majuscule. Pour corriger le problème, il suffit d'installer une petite applet qui se glisse sur un tableaux de bord Gnome : lock_leys-applet. Ouvrons encore une fois un terminal et tapons-y :

sudo apt-get install lock-keys-applet

Pour l'ajouter, faisons un clic droit sur un de nos tableaux Gnome > ajouter au tableau de bord > Lock Keys. Veille du disque dur

Sur certain notebook (et certain EeePc) , la gestion de l'énergie pour le disque dur est très mal gérée, conséquence : les têtes de lectures/écriture se parquent trop souvent, le disque voit son espérance de vie très réduite. Le diagnostic est simple : si nous entendons le disque dur de notre ordinateur faire des clic relativement régulièrement (je ne parles pas de l'habituel grattage lorsque nous écrivons, lisons sur celui-ci). Pour régler le soucis, ouvrons le terminal et rentrons la commande suivante :

sudo hdparm -B 200 /dev/sda && echo -e '#!/bin/shnhdparm -B 200 /dev/sda' > /tmp/99-hdd-spin-fix.sh && for i in start suspend resume; do sudo install /tmp/99-hdd-spin-fix.sh /etc/acpi/$i.d; done Conclusion

Et voilà un Eeepc 1000h sous Ubuntu Intrepid Ibex fonctionnant parfaitement : Bluetooth, Wifi, touches spéciales... Pour rédiger cet article, j'ai trouvé les informations sur :

• Le tutoriel d'installation sur le site Array.org
• Ubuntu Hardy Heron sur EeePC 1000h sur Ubuntu-fr
• Le problème du disque dur sur Ubuntu-fr.org
• Le forum Ubuntu-fr

Billet original de E-PhasE.Votez pour cet article sur le Planet Libre.

The last time we heard from J. Michael Straczynski about his remake-but-not-really of The Forbidden Planet, it ended up being a lot of misquotes that the screenwriter quickly refuted. MTV caught up with him this week, and he explained his take on the classic sci-fi film: "I've always wanted to do something involving Forbidden Planet. It's my favorite science-fiction film of all time. I've watched the rights go from one company to the next. I heard that the rights at Dreamworks were about to expire and I went to Joel Silver and said I think if you move quickly you can grab it and I can write it. And he did. It's the dream of a lifetime to play in that universe."

While he remained relatively tight-lipped on the plot, Straczynski was careful to point out what it isn't. "I told Joel [Silver] this is how you do Forbidden Planet without pissing on the original that no one has ever thought of. When I told [the idea] to him, his eyes lit up. It's not a remake. It's not a reimagining. It's not exactly a prequel. You'll have to see it. It's something that no one has thought of when it comes to this storyline."

As he lived just before the invention of the telescope, Tycho Brahe relied on his keen eyes to make observations that changed the science. Yet his face was more remarkable for a different feature: a golden nose. In 1566, when Tycho was a 20-year-old student at the University of Rostock in Germany, he became embroiled in a drunken argument with another Danish nobleman named Manderup Parsbjerg. A duel ensued – in the dark – in the course of which Parsbjerg’s rapier lopped off much of the bridge of the future astronomer’s nose. To mask the damage, Tycho – like Galileo Galilei, he is generally known by his first name – designed himself a metallic nose-job. Using an alloy of silver and gold, he fashioned a false nose that is said to have been remarkably realistic. Thenceforth, he carried a special paste around with him – historians differ on whether this was for reattaching the nose, or for polishing it. The man with the golden nose may, in fact, have had several replacements. When his body was exhumed in 1901, on the 300th anniversary of his death, no precious prosthesis was found. His skull however, was stained green where the nose would have been. This may indicate that copper – which oxidises to a green colour – was used to build his nose. Some speculate that he had a lighter copper nose for everyday use, and saved the heavier silver-gold version for special occasions. Alternatively, a grave robber might have stolen the precious metal, and substituted a cheap alternative. Tycho’s nasal appendage was far from his only unusual possession: at his family seat, Knutstorp castle, he kept a pet moose. His prized companion met a tragic end, falling downstairs after drinking beer at a banquet. Another member of the nobleman’s unorthodox household was a dwarf named Jepp, whom Tycho considered to be clairvoyant. Tycho, who at one stage owned 1 per cent of all the wealth in Denmark, would often order silence at his feasts and make his guests listen to Jepp’s pronouncements. For all his quirks, however, Tycho was an astronomer of immense stature. Besides observing the supernova of 1572, he catalogued more than a thousand new stars, and made some of the most accurate measurements of celestial movements yet accomplished. In his latter years, when working in Prague, he employed Johannes Kepler as his assistant. After Tycho’s death, Kepler was to use his master’s records of the movement of Mars to establish the laws of planetary motion. Tycho, however, was off the scent on one critical astronomical matter: though well aware of Copernicus’s theory that the Earth orbits the Sun, he was unable to accept it. Instead, he proposed his own idiosyncratic cosmology, by which the Sun orbited the Earth, while the remaining planets orbited the Sun.

Les systèmes Gnu/Linux sont réputés pour leurs stabilité, en règle générale on installe sa distribution favorite, on y met ses logiciels préférés et l’on configure le tout aux “petits oignons”. Mais voilà une fois que tout cela est fait, on s’embête un peu !! Alors que faire pour passer son temps avec nos fameux Logiciels Libres ? Nous allons donc voir comment combler l’ennuie qui vous ronge devant votre système parfait (pour vous).

Découvrir :

Le plus simple pour un Geek est de tester les différentes distributions mises à dispositions sur le net, et il y en a pour tout les goûts tellement l’offre est immense !! C’est un excellent moyen de passer le temps où sa vie , et puis il n’est pas nécessaire de faire les installations en “dur”, testez les simplement sous VirtualBox par exemple...

Pour les moins Geek, vous pouvez changer votre gestionnaire de fenêtres : Vous êtes sous Gnome ? Alors pourquoi ne pas aller voir du coté de chez KDE ou encore OpenBox, XFCE, Fluxbox... Les gestionnaires de fenêtres ne manquent pas non plus alors n’hésitez pas à les découvrir.

Autre solution : Débranchez votre souris !! Et oui au bout de 15 jours sans votre mulot favori vous comprendrez très vite que c’est une perte de temps.

Partager :

Vous avez sûrement testé plusieurs logiciels, mais aussi peut être eu beaucoup de mal à en découvrir toutes les subtilités. Peut être même que la documentation est malheureusement quasi inexistante, alors faites part de vos connaissances en agrémentant la documentation d’un wiki par exemple ou encore écrire un petit “How to” sur votre blog.

Il en va de même si vous avez réussi à faire fonctionner du matériel mal supporté (imprimantes, GPS, scanners, etc...), informez en la communauté, cela ne sera que bénéfique et permettra d’aider les débutants.

Il peut être aussi intéressant d’apprendre un langage informatique, le bash est très accessible et vous permettra de créer vos petits scripts que vous partagerez par la suite.

Aider :

Vous pouvez très bien aider au développement des logiciels, inutile d’être un expert en langage C pour venir en aide : Un simple rapport de bug ou une recommandation fera l’affaire. La traduction des logiciels demande un travail énorme alors si vous en avez les compétences, proposez votre aide.

Pour finir vous pouvez proposer un nouveau thème aux programmeurs d’Ubuntu (Marre du marron) !!

Voilà j’en ai fini, en espérant que vous passerez à présent votre temps utilement .

EDIT : Vous pouvez aussi passer/perdre votre temps en écrivant des articles comme celui-ci.

Yahoo, one of the largest web sites on the planet, is being plagued by series of problems related to Domain Name System (DNS). A test using Gomez’s testing service shows error messages in certain cities such as Chicago. Others are experiencing slower access to Yahoo web sites, including the home page. There is already some chatter about this on Twitter, where people are pointing to problems with Yahoo Finance pages. If you have experienced these problems do let me know in the comments. I am going to try and talk to Yahoo and get to the bottom of it as quickly as I can.

J’ai l’honneur de vous annoncer que le site Capof’s Space est maintenant hébergé gracieusement dans les serveurs de TuxFamily.

img class=face src=http://planet.ubuntu.com/heads/keescook.png alt= pCare of Mike Owens and a href=http://blog.dustinkirkland.com/search/label/UbuntuDustin Kirkland/a, a href=https://launchpad.net/ubuntu/+source/bogosecbogosec/a has been uploaded to Jaunty (in the a href=https://launchpad.net/ubuntu/jaunty/+queue?queue_state=0#038;queue_text=bogosecNEW queue/a at the moment). It is a source-code analyzer framework with plugins for a href=http://lintian.debian.org/lintian/a, a href=http://www.fortify.com/security-resources/rats.jsprats/a, and a href=http://www.dwheeler.com/flawfinder/flawfinder/a. Out of curiousity, I a href=http://people.ubuntu.com/~kees/bogosec/ran it/a on all of Intrepid main. Highest 5 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/scores.txtscores/a were:/p ol li0.717338929043293 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/lsscsilsscsi/a/li li0.612729234088457 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/nevownevow/a/li li0.561151781356762 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/powertoppowertop/a/li li0.431034482758621 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/language-pack-tk-baselanguage-pack-tk-base/a/li li0.431034482758621 a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/language-pack-se-baselanguage-pack-se-base/a/li /ol pAs Dustin reminded me, bogosec seems biased against smaller code bases. In the case of the lang packs, the score is entirely from lintian. Both lsscsi and powertop deal mostly with input from kernel strings, so while they scored highly, I doubt either is actually vulnerable to very much. I haven#8217;t looked at nevow yet. Also, both rats and flawfinder yell about things that are mitigated by a href=https://wiki.ubuntu.com/CompilerFlagscompiler flags/a (e.g. -D_FORTIFY_SOURCE=2) so those warnings are less interesting too./p pReally, this all boils down to #8220;we need better code analyzers#8221;. The best tool will be one that predicts CVE counts (I would expect the a href=http://people.ubuntu.com/~kees/bogosec/intrepid-main/linuxLinux kernel/a to be at the top, since it has the all-time highest number of a href=http://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=linux+kernelCVEs filed against it/a)./p pTo get closer to reality, I think just doing a normal package build and scanning for stderr output would be meaningful (gcc has plenty of built-in checks already). Steve Beattie suggested writing a plugin for a href=http://www.kernel.org/pub/software/devel/sparse/sparse/a, too./p

img class=face src=http://planet.ubuntu.com/heads/jono.png alt= pWhen I was a kid, I owned a a href=http://en.wikipedia.org/wiki/Sega_GenesisSega Megadrive/a (Sega Genesis for my American friends). I spent hours on that thing. Sonic The Hedgehog. Streets Of Rage. Desert Strike. Toejam And Earl. I loved it./p pOne game that was released was a href=http://en.wikipedia.org/wiki/Carmen_SandiegoWhere In The World Is Carmen Sandiego?/a Back then it was marketed as emedutainment/em: essentially a sneaky way for parents to infiltrate their kid#8217;s leisure time with learning under the premise of it being #8220;fun#8221;. Of course, kids are smarter than parents give them credit for. Kids were wise to this and often avoided games like that like the plague. The mind of a 12 year-old concluded that enough time is spent in front of teachers, workbooks and exams without it invading precious Sega time. I was one such kid. I emhated/em the idea of edutainment. I didnt want to learn with my Megadrive, I wanted to shoot things with very large, very loud, deeply pixelated guns./p pThings change when you grow up (yes, I have grown up, smart arses). I now love learning. I love reading. I spend hours drowning in Wikipedia and exploring our world, our history and our patchwork of cultures. I love learning about people#8217;s experiences, perspectives and attitudes. I no longer have the 12 year-old mentality that learning is for school time. Learning really is genuinely emfun/em./p pNaturally, there are some subjects I like to learn about in more detail. Community (zing!). Computers. Free Software. Free Culture. Music. There are however some subjects that I develop a curiosity about and feel an urge to investigate. These subjects are not part of my daily interests and hobbies, but are temporary avenues of curiosity./p pOne recent example for me is emHistorical Jesus/em. A few days ago I read everything Wikipedia had to offer about about the subject. This was triggered originally by a history TV show which in turn inspired me to buy a book about significant events in human history. In this book I read about Jesus#8217;s Crucifixion and decided to further refresh my knowledge of the subject by hitting up Wikipedia. In this example we see two distinctive concepts: emPassive Education/em and emContent Aggregation and Linking/em:/p ul liemPassive Education/em - in my example of Historical Jesus, my primary focus was gathering the facts and the story. I was happy for this subject#8217;s learning to be passive. I was happy to merely consume the content and not interact with it much more than selecting what to learn./li liemContent Aggregation and Linking/em - learning has links and connections. I first watched a show about history. This intrigued me to buy the book on historical events. A section in that book inspired me to access specific content on Wikipedia. The thread that connected these different resources together was the subject of Historical Jesus and I aggregated the different pieces of knowledge together in my brain. My current knowledge of Historical Jesus draws from these different resources./li /ul pWhen we learn about our primary interests, learning is different. Our desire is often for emActive Learning/em. We not only want to know the subject, but we want to immerse ourselves in the execution and debate of it too. Much of this is not only collating general knowledge, as I did with Historical Jesus, but learning about more localised information too. When I learn about music, I want to know about local bands. I want to know when my favourite bands are coming to my area. I want to hear about music groups, gigs, and conventions near to me. I want to know about special offers in local music stores. In a nutshell, I don#8217;t just want to consume, I want to emparticipate/em./p pIn recent years, computers and the Internet have made both Active and Passive Learning incredibly accessible. The web has bolstered passive learning resources, and active learning has been thrusted towards us with online communities, social networking, community groups and discussion boards. No matter what you want to know about, the Internet can help you in both Passive and Active ways/p pBut lets get back to emWhere In The World Is Carmen Sandiego?/em. Although I could not stand the concept of emedutainment/em at the time, what that game emdid/em do that intrigues me is that it delivered education to people automatically. The education was emassociative/em: topics and concepts were delivered to you as you played the game./p pI find this really interesting. I find the concept of linking and associating different types of education and resources fascinating. This also holds hu
