+    <strong>18ème édition</strong>
+    <br><br>
+
+    <p>
+    Le 12 mai 2023 en visite à Dunkerque, ville du Nord érigée par l’Élysée en symbole de sa politique de réindustrialisation tournée vers la transition écologique, Emmanuel Macron a confirmé l’implantation d’une usine de batteries du taïwanais Prologium (3000 emplois, investissement de 5,2 milliards d’euros) ainsi que la construction prochaine d’une usine de batteries électriques au lithium (1700 emplois, investissement de 1,5 milliard d’euros) fruit d’un partenariat entre le français Orano et la société chinoise XTC. Selon le vice-président de ProLogium1, ces projets de « gigafactorys » constituent un « véritable écosystème pour les batteries dans le nord de la France ».
+    </p>
+
+    <p>
+    A quelle « écologie » cet « écosystème » fait-il référence ? S’il procède bien d’une « planification écologique » s’appuie-t-il sur des dynamiques territoriales durables ou répond-il d’abord à un contexte géopolitique national et international ? Ne faut-il pas renoncer à la notion d’écosystème quand celle-ci n’a plus aucun des caractères anti-entropiques et historiques que l’on trouve dans le vivant ?
+    </p>
+
+    <p>
+    Dans le cadre de nos entretiens, pour mieux comprendre les enjeux et les tensions et proposer de nouvelles approches industrielles, nous partons de la richesse et de la diversité des « localités » qui produisent de nouveaux savoirs. Est-ce que les fablabs, les usines distribuées, les circuits courts, l’économie circulaire, les projets low-tech et les coopératives numériques peuvent contribuer à une dynamique d’innovation ascendante qui crée une « nouvelle écologie industrielle » ?
+    </p>
+
+    <br>
+    <h3>Programme</h3>
+    <br>
+    <p><strong>Mercredi 18 décembre&nbsp;:</strong></p>
+    <br>
+    <p><strong>09h30-12h30 - Session 1 : Transition ou bifurcation ? Regards croisés sur l’histoire et les politiques industrielles</strong></p>
+    <p>Transition ou bifurcation ? Écosystèmes ou milieux ? Planification centralisée ou innovation ascendante ? Modèles physiques ou modèles biologiques ? Quels regards pouvons-nous porter sur l’histoire de l’industrie et des politiques industrielles et sur leurs fondements épistémologiques et sémiotiques pour dégager une nouvelle critique et une nouvelle fabrique de l’industrie ?</p>

+    <p><strong>14h00 : 16h30 - Session 2 : Production et reproduction : l’industrie et le vivant</strong></p>
+    <p>Si l’industrie produit, le vivant se reproduit, mais cette différence n’est-elle pas mise à mal alors que l’agriculture est devenue industrielle et que se pose la question d’une écologie de l’industrie ? Qu’est-ce donc que produire de l’artisanat à l’industrie, et, en biologie, de l’autopoïse à la reproduction ? Plus encore, ne devons-nous pas repenser la question de la production alors que nos productions mettent à mal le vivant, y compris nous-mêmes ? Session en prolongation des recherches menées au sein du projet Regeneraction.</p>

+    <p><strong>10h00 : 13h00 - Session 4 : Eco-technologie, techno-esthétique et communautés alternatives</strong></p>
+    <p>Pour Gilbert Simondon, l’individu (et par extension l’objet technique) qui optimise le « rendement » de son rapport à son milieu fonde une « techno-esthétique » à tel point que nous devrions pouvoir distinguer, dans le monde industriel, les systèmes monstrueux ou infidèles à leur milieu, des systèmes optimisés dans leur concrétisation, c’est-à-dire aussi proches des systèmes biologiques. Comment cette approche que l’on peut qualifier d’« éco-technologique » peut-elle modifier nos démarches d’ingénierie et de design mais aussi les pratiques esthétiques elles-mêmes ? Comment les communautés alternatives et notamment dans le champ de l’écologie peuvent ainsi se réapproprier un discours sur l’industrie ?</p>

+    <p><strong>14h30 : 17h00 - Session 5 : Écologie et économie de l’industrie : la question de l’investissement</strong></p>
+    <p>Même si les deux notions gagnent à être distinguées, industrie et économie vont de pair. Cette session s’interroge sur les nouvelles écologies/organologies des territoires et leur impact sur les dynamiques économiques durables. Elle tente aussi d’éclairer comment une écologie de l’industrie implique une nouvelle écologie de la monnaie.</p>

+    <br>
+    <p><strong>17h00 : 18h30 - Session 6 : Gestion des données, communs numériques et rôle des standards dans la nouvelle écologie du numérique</strong></p>
+    <p>Comment le numérique, souvent pointé du doigt pour son impact environnemental à l’heure du fort développement des IA génératives, peut-il dessiner de nouveaux écosystèmes à même de mieux se réapproprier son « contexte » local et global ? Comment les standards ouverts et notamment le logiciel libre peuvent-ils constituer des espaces de capacitation, d’autonomie, d’invention et d’industrie ?</p>

This is different from most media players, as\n * audio is more often used as the primary timing source. For the foreseeable future, VHS\n * will continue to use video as the primary timing source, due to the current logic and\n * expectations built around it.\n\n * Since the timing follows video, in order to maintain sync, the video loader is\n * responsible for setting both audio and video source buffer timestamp offsets.\n *\n * Setting different values for audio and video source buffers could lead to\n * desyncing. The following examples demonstrate some of the situations where this\n * distinction is important. Note that all of these cases involve demuxed content. When\n * content is muxed, the audio and video are packaged together, therefore syncing\n * separate media playlists is not an issue.\n *\n * CASE 1: Audio prepares to load a new timeline before video:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:                     ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader              ^\n *\n * In the above example, the audio loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the video loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the audio loader goes ahead and loads and appends the 6th segment before the video\n * loader crosses the discontinuity, then when appended, the 6th audio segment will use\n * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,\n * the audio loader must provide the audioAppendStart value to trim the content in the\n * transmuxer, and that value relies on the audio timestamp offset. Since the audio\n * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the\n * segment until that value is provided.\n *\n * CASE 2: Video prepares to load a new timeline before audio:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:             ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader                      ^\n *\n * In the above example, the video loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the audio loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the video loader goes ahead and loads and appends the 6th segment, then once the\n * segment is loaded and processed, both the video and audio timestamp offsets will be\n * set, since video is used as the primary timing source. This is to ensure content lines\n * up appropriately, as any modifications to the video timing are reflected by audio when\n * the video loader sets the audio and video timestamp offsets to the same value. However,\n * setting the timestamp offset for audio before audio has had a chance to change\n * timelines will likely lead to desyncing, as the audio loader will append segment 5 with\n * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.\n *\n * CASE 3: When seeking, audio prepares to load a new timeline before video\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:           ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader            ^\n *\n * In the above example, both audio and video loaders are loading segments from timeline\n * 0, but imagine that the seek originated from timeline 1.\n *\n * When seeking to a new timeline, the timestamp offset will be set based on the expected\n * segment start of the loaded video segment. In order to maintain sync, the audio loader\n * must wait for the video loader to load its segment and update both the audio and video\n * timestamp offsets before it may load and append its own segment. This is the case\n * whether the seek results in a mismatched segment request (e.g., the audio loader\n * chooses to load segment 3 and the video loader chooses to load segment 4) or the\n * loaders choose to load the same segment index from each playlist, as the segments may\n * not be aligned perfectly, even for matching segment indexes.\n *\n * @param {Object} timelinechangeController\n * @param {number} currentTimeline\n *        The timeline currently being followed by the loader\n * @param {number} segmentTimeline\n *        The timeline of the segment being loaded\n * @param {('main'|'audio')} loaderType\n *        The loader type\n * @param {boolean} audioDisabled\n *        Whether the audio is disabled for the loader.

If audio and video streams are not perfectly in-sync, then\n      //    the mapping will be off for one of the streams, dependent on which one was\n      //    first saved (see (1)).\n      // 3) Primary timing goes by video in VHS, so the mapping should be video.\n      //\n      // Since the audio loader will wait for the main loader to load the first segment,\n      // the main loader will save the first timeline mapping, and ensure that there won't\n      // be a case where audio loads two segments without saving a mapping (thus leading\n      // to missing segment timing info).\n      this.syncController_.saveSegmentTimingInfo({\n        segmentInfo,\n        shouldSaveTimelineMapping: this.loaderType_ === 'main'\n      });\n    }\n    const segmentDurationMessage = getTroublesomeSegmentDurationMessage(segmentInfo, this.sourceType_);\n    if (segmentDurationMessage) {\n      if (segmentDurationMessage.severity === 'warn') {\n        videojs.log.warn(segmentDurationMessage.message);\n      } else {\n        this.logger_(segmentDurationMessage.message);\n      }\n    }\n    this.recordThroughput_(segmentInfo);\n    this.pendingSegment_ = null;\n    this.state = 'READY';\n    if (segmentInfo.isSyncRequest) {\n      this.trigger('syncinfoupdate'); // if the sync request was not appended\n      // then it was not the correct segment.\n      // throw it away and use the data it gave us\n      // to get the correct one.\n\n      if (!segmentInfo.hasAppendedData_) {\n        this.logger_(`Throwing away un-appended sync request ${segmentInfoString(segmentInfo)}`);\n        return;\n      }\n    }\n    this.logger_(`Appended ${segmentInfoString(segmentInfo)}`);\n    this.addSegmentMetadataCue_(segmentInfo);\n    this.fetchAtBuffer_ = true;\n    if (this.currentTimeline_ !== segmentInfo.timeline) {\n      this.timelineChangeController_.lastTimelineChange({\n        type: this.loaderType_,\n        from: this.currentTimeline_,\n        to: segmentInfo.timeline\n      }); // If audio is not disabled, the main segment loader is responsible for updating\n      // the audio timeline as well.

The\n  primary way of interacting with a promise is through its `then` method, which\n  registers callbacks to receive either a promise\'s eventual value or the reason\n  why the promise cannot be fulfilled.\n\n  Terminology\n  -----------\n\n  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n  - `thenable` is an object or function that defines a `then` method.\n  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n  - `exception` is a value that is thrown using the throw statement.\n  - `reason` is a value that indicates why a promise was rejected.\n  - `settled` the final resting state of a promise, fulfilled or rejected.\n\n  A promise can be in one of three states: pending, fulfilled, or rejected.\n\n  Promises that are fulfilled have a fulfillment value and are in the fulfilled\n  state.  Promises that are rejected have a rejection reason and are in the\n  rejected state.  A fulfillment value is never a thenable.\n\n  Promises can also be said to *resolve* a value.  If this value is also a\n  promise, then the original promise\'s settled state will match the value\'s\n  settled state.  So a promise that *resolves* a promise that rejects will\n  itself reject, and a promise that *resolves* a promise that fulfills will\n  itself fulfill.\n\n\n  Basic Usage:\n  ------------\n\n  ```js\n  let promise = new Promise(function(resolve, reject) {\n    // on success\n    resolve(value);\n\n    // on failure\n    reject(reason);\n  });\n\n  promise.then(function(value) {\n    // on fulfillment\n  }, function(reason) {\n    // on rejection\n  });\n  ```\n\n  Advanced Usage:\n  ---------------\n\n  Promises shine when abstracting away asynchronous interactions such as\n  `XMLHttpRequest`s.\n\n  ```js\n  function getJSON(url) {\n    return new Promise(function(resolve, reject){\n      let xhr = new XMLHttpRequest();\n\n      xhr.open(\'GET\', url);\n      xhr.onreadystatechange = handler;\n      xhr.responseType = \'json\';\n      xhr.setRequestHeader(\'Accept\', \'application/json\');\n      xhr.send();\n\n      function handler() {\n        if (this.readyState === this.DONE) {\n          if (this.status === 200) {\n            resolve(this.response);\n          } else {\n            reject(new Error(\'getJSON: `\' + url + \'` failed with status: [\' + this.status + \']\'));\n          }\n        }\n      };\n    });\n  }\n\n  getJSON(\'/posts.json\').then(function(json) {\n    // on fulfillment\n  }, function(reason) {\n    // on rejection\n  });\n  ```\n\n  Unlike callbacks, promises are great composable primitives.\n\n  ```js\n  Promise.all([\n    getJSON(\'/posts\'),\n    getJSON(\'/comments\')\n  ]).then(function(values){\n    values[0] // => postsJSON\n    values[1] // => commentsJSON\n\n    return values;\n  });\n  ```\n\n  @class Promise\n  @param {Function} resolver\n  Useful for tooling.\n  @constructor\n*/\n\nvar Promise$1 = function () {\n  function Promise(resolver) {\n    this[PROMISE_ID] = nextId();\n    this._result = this._state = undefined;\n    this._subscribers = [];\n\n    if (noop !== resolver) {\n      typeof resolver !== \'function\' && needsResolver();\n      this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n    }\n  }\n\n  /**\n  The primary way of interacting with a promise is through its `then` method,\n  which registers callbacks to receive either a promise\'s eventual value or the\n  reason why the promise cannot be fulfilled.\n   ```js\n  findUser().then(function(user){\n    // user is available\n  }, function(reason){\n    // user is unavailable, and you are given the reason why\n  });\n  ```\n   Chaining\n  --------\n   The return value of `then` is itself a promise.  This second, \'downstream\'\n  promise is resolved with the return value of the first promise\'s fulfillment\n  or rejection handler, or rejected if the handler throws an exception.\n   ```js\n  findUser().then(function (user) {\n    return user.name;\n  }, function (reason) {\n    return \'default name\';\n  }).then(function (userName) {\n    // If `findUser` fulfilled, `userName` will be the user\'s name, otherwise it\n    // will be `\'default name\'`\n  });\n   findUser().then(function (user) {\n    throw new Error(\'Found user, but still unhappy\');\n  }, function (reason) {\n    throw new Error(\'`findUser` rejected and we\'re unhappy\');\n  }).then(function (value) {\n    // never reached\n  }, function (reason) {\n    // if `findUser` fulfilled, `reason` will be \'Found user, but still unhappy\'.\n    // If `findUser` rejected, `reason` will be \'`findUser` rejected and we\'re unhappy\'.\n  });\n  ```\n  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n   ```js\n  findUser().then(function (user) {\n    throw new PedagogicalException(\'Upstream error\');\n  }).then(function (value) {\n    // never reached\n  }).then(function (value) {\n    // never reached\n  }, function (reason) {\n    // The `PedgagocialException` is propagated all the way down to here\n  });\n  ```\n   Assimilation\n  ------------\n   Sometimes the value you want to propagate to a downstream promise can only be\n  retrieved asynchronously. This can be achieved by returning a promise in the\n  fulfillment or rejection handler. The downstream promise will then be pending\n  until the returned promise is settled. This is called *assimilation*.\n   ```js\n  findUser().then(function (user) {\n    return findCommentsByAuthor(user);\n  }).then(function (comments) {\n    // The user\'s comments are now available\n  });\n  ```\n   If the assimliated promise rejects, then the downstream promise will also reject.\n   ```js\n  findUser().then(function (user) {\n    return findCommentsByAuthor(user);\n  }).then(function (comments) {\n    // If `findCommentsByAuthor` fulfills, we\'ll have the value here\n  }, function (reason) {\n    // If `findCommentsByAuthor` rejects, we\'ll have the reason here\n  });\n  ```\n   Simple Example\n  --------------\n   Synchronous Example\n   ```javascript\n  let result;\n   try {\n    result = findResult();\n    // success\n  } catch(reason) {\n    // failure\n  }\n  ```\n   Errback Example\n   ```js\n  findResult(function(result, err){\n    if (err) {\n      // failure\n    } else {\n      // success\n    }\n  });\n  ```\n   Promise Example;\n   ```javascript\n  findResult().then(function(result){\n    // success\n  }, function(reason){\n    // failure\n  });\n  ```\n   Advanced Example\n  --------------\n   Synchronous Example\n   ```javascript\n  let author, books;\n   try {\n    author = findAuthor();\n    books  = findBooksByAuthor(author);\n    // success\n  } catch(reason) {\n    // failure\n  }\n  ```\n   Errback Example\n   ```js\n   function foundBooks(books) {\n   }\n   function failure(reason) {\n   }\n   findAuthor(function(author, err){\n    if (err) {\n      failure(err);\n      // failure\n    } else {\n      try {\n        findBoooksByAuthor(author, function(books, err) {\n          if (err) {\n            failure(err);\n          } else {\n            try {\n              foundBooks(books);\n            } catch(reason) {\n              failure(reason);\n            }\n          }\n        });\n      } catch(error) {\n        failure(err);\n      }\n      // success\n    }\n  });\n  ```\n   Promise Example;\n   ```javascript\n  findAuthor().\n    then(findBooksByAuthor).\n    then(function(books){\n      // found books\n  }).catch(function(reason){\n    // something went wrong\n  });\n  ```\n   @method then\n  @param {Function} onFulfilled\n  @param {Function} onRejected\n  Useful for tooling.\n  @return {Promise}\n  */\n\n  /**\n  `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n  as the catch block of a try/catch statement.\n  ```js\n  function findAuthor(){\n  throw new Error(\'couldn\'t find that author\');\n  }\n  // synchronous\n  try {\n  findAuthor();\n  } catch(reason) {\n  // something went wrong\n  }\n  // async with promises\n  findAuthor().catch(function(reason){\n  // something went wrong\n  });\n  ```\n  @method catch\n  @param {Function} onRejection\n  Useful for tooling.\n  @return {Promise}\n  */\n\n\n  Promise.prototype.catch = function _catch(onRejection) {\n    return this.then(null, onRejection);\n  };\n\n  /**\n    `finally` will be invoked regardless of the promise\'s fate just as native\n    try/catch/finally behaves\n  \n    Synchronous example:\n  \n    ```js\n    findAuthor() {\n      if (Math.random() > 0.5) {\n        throw new Error();\n      }\n      return new Author();\n    }\n  \n    try {\n      return findAuthor();

Sometimes it\'s called a "filter",\n// but that\'s not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored.  (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it\'s not a\n// necessarily symmetric or synchronous transformation.  For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here\'s how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes.  When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there\'s a lot of pending writes\n// buffered up.  When you call read(), that calls _read(n) until\n// there\'s enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer.  When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb\'s as it consumes chunks.  If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit \'readable\' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk.  However,\n// a pathological inflate type of transform can cause excessive buffering\n// here.  For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output.  In this case, you could write a very small\n// amount of input, and end up with a very large amount of output.  In\n// such a pathological inflating mechanism, there\'d be no way to tell\n// the system to stop doing the transform.  A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n\n\n\nmodule.exports = Transform;\n\nvar Duplex = __nested_webpack_require_411682__(/*! ./_stream_duplex */ "./node_modules/readable-stream/lib/_stream_duplex.js");\n\n/*<replacement>*/\nvar util = __nested_webpack_require_411682__(/*! core-util-is */ "./node_modules/core-util-is/lib/util.js");\nutil.inherits = __nested_webpack_require_411682__(/*! inherits */ "./node_modules/inherits/inherits_browser.js");\n/*</replacement>*/\n\nutil.inherits(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n  var ts = this._transformState;\n  ts.transforming = false;\n\n  var cb = ts.writecb;\n\n  if (!cb) {\n    return this.emit(\'error\', new Error(\'write callback called multiple times\'));\n  }\n\n  ts.writechunk = null;\n  ts.writecb = null;\n\n  if (data != null) // single equals check for both `null` and `undefined`\n    this.push(data);\n\n  cb(er);\n\n  var rs = this._readableState;\n  rs.reading = false;\n  if (rs.needReadable || rs.length < rs.highWaterMark) {\n    this._read(rs.highWaterMark);\n  }\n}\n\nfunction Transform(options) {\n  if (!(this instanceof Transform)) return new Transform(options);\n\n  Duplex.call(this, options);\n\n  this._transformState = {\n    afterTransform: afterTransform.bind(this),\n    needTransform: false,\n    transforming: false,\n    writecb: null,\n    writechunk: null,\n    writeencoding: null\n  };\n\n  // start out asking for a readable event once data is transformed.\n  this._readableState.needReadable = true;\n\n  // we have implemented the _read method, and done the other things\n  // that Readable wants before the first _read call, so unset the\n  // sync guard flag.\n  this._readableState.sync = false;\n\n  if (options) {\n    if (typeof options.transform === \'function\') this._transform = options.transform;\n\n    if (typeof options.flush === \'function\') this._flush = options.flush;\n  }\n\n  // When the writable side finishes, then flush out anything remaining.\n  this.on(\'prefinish\', prefinish);\n}\n\nfunction prefinish() {\n  var _this = this;\n\n  if (typeof this._flush === \'function\') {\n    this._flush(function (er, data) {\n      done(_this, er, data);\n    });\n  } else {\n    done(this, null, null);\n  }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n  this._transformState.needTransform = false;\n  return Duplex.prototype.push.call(this, chunk, encoding);\n};\n\n// This is the part where you do stuff!\n// override this function in implementation classes.\n// \'chunk\' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

The following examples demonstrate some of the situations where this\n * distinction is important. Note that all of these cases involve demuxed content. When\n * content is muxed, the audio and video are packaged together, therefore syncing\n * separate media playlists is not an issue.\n *\n * CASE 1: Audio prepares to load a new timeline before video:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:                     ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader              ^\n *\n * In the above example, the audio loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the video loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the audio loader goes ahead and loads and appends the 6th segment before the video\n * loader crosses the discontinuity, then when appended, the 6th audio segment will use\n * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,\n * the audio loader must provide the audioAppendStart value to trim the content in the\n * transmuxer, and that value relies on the audio timestamp offset. Since the audio\n * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the\n * segment until that value is provided.\n *\n * CASE 2: Video prepares to load a new timeline before audio:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:             ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader                      ^\n *\n * In the above example, the video loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the audio loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the video loader goes ahead and loads and appends the 6th segment, then once the\n * segment is loaded and processed, both the video and audio timestamp offsets will be\n * set, since video is used as the primary timing source. This is to ensure content lines\n * up appropriately, as any modifications to the video timing are reflected by audio when\n * the video loader sets the audio and video timestamp offsets to the same value. However,\n * setting the timestamp offset for audio before audio has had a chance to change\n * timelines will likely lead to desyncing, as the audio loader will append segment 5 with\n * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.\n *\n * CASE 3: When seeking, audio prepares to load a new timeline before video\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:           ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader            ^\n *\n * In the above example, both audio and video loaders are loading segments from timeline\n * 0, but imagine that the seek originated from timeline 1.\n *\n * When seeking to a new timeline, the timestamp offset will be set based on the expected\n * segment start of the loaded video segment. In order to maintain sync, the audio loader\n * must wait for the video loader to load its segment and update both the audio and video\n * timestamp offsets before it may load and append its own segment. This is the case\n * whether the seek results in a mismatched segment request (e.g., the audio loader\n * chooses to load segment 3 and the video loader chooses to load segment 4) or the\n * loaders choose to load the same segment index from each playlist, as the segments may\n * not be aligned perfectly, even for matching segment indexes.\n *\n * @param {Object} timelinechangeController\n * @param {number} currentTimeline\n *        The timeline currently being followed by the loader\n * @param {number} segmentTimeline\n *        The timeline of the segment being loaded\n * @param {('main'|'audio')} loaderType\n *        The loader type\n * @param {boolean} audioDisabled\n *        Whether the audio is disabled for the loader.

Functions\n// ----------------\n// Our most fundamental functions operate on any JavaScript object.\n// Most functions in Underscore depend on at least one function in this section.\n\n// A group of

                                         Pour participer au Polemic tweet, un client twitter intégrant des fonctionnalités spéciales est disponible sur <a href='client.php'>la page de live</a> , mais vous pouvez aussi utiliser votre client habituel. <br/><br/>

Sur cette page le HashTag de l’événement est déjà inséré dans l’espace de rédaction du tweet, ensuite a l’aide du jeu  de boutons suivants vous pouvez positionner votre tweet dans l’espace polémique :<br/>

                                         A l’issue de la conférence, le dispositif Polemic Tweet produit un nouveau type d’interface qui permet de parcourir l’enregistrement vidéo en utilisant une représentation de la polémique qui s’est engagée sur le média social. Cette interface est une ligne de temps munie d’un diagramme en bâtons qui aggrège l’ensemble des tweets et permet de voir les « point chauds » de la  polémique durant l'événement.
