+# IPFS Weekly #9
+
+[IPFS](//ipfs.io/) is a new hypermedia distribution protocol, addressed by content and identities, aiming to make the web faster, safer, and more open. In these posts, we highlight some of the development that has happened in the past week. For anyone looking to get involved, follow the embedded hyperlinks, search the wealth of information on [GitHub](//github.com/ipfs) or join us on [IRC](//webchat.freenode.net/?channels=ipfs) (#ipfs on the Freenode network).

+If you would like to get this update as an email, sign up for our [weekly newsletter](//tinyletter.com/ipfsweekly)!
+
+Here are some of the highlights for the [March 28th](//github.com/ipfs/pm/issues/98) sprint:
+
+## Updates
+
+### Package Managers
+
+Package managers have been a large topic of discussion recently. Mostly, this is because of an issue with an author of some heavily used [npm](https://npmjs.com) packages unpublishing all of his modules simultaneously. One of these was `left-pad`, which was used by thousands of builds globally, all of which broke when the package was removed. A great writeup of what happened is on the [npm.js blog here](http://blog.npmjs.org/post/141577284765/kik-left-pad-and-npm); they took this very seriously, and shortly after [changed their unpublish policy](http://blog.npmjs.org/post/141905368000/changes-to-npms-unpublish-policy) as a direct result.
+
+Many people jumped to IPFS as a possible solution to this problem. With a permanent filesystem, unpublishing wouldn't be possible. Here's one post titled [How to use IPFS to fix npm](http://amreldib.com/blog/HowToUseIpfsToFixNpm); here's [an issue](https://github.com/ipmjs/ipmjs/issues/9) on a new GitHub organization, ipmjs, trying to find consensus on how to fix npm using a permanent storage system; here's an npm module, [cowpen](https://www.npmjs.com/package/cowpen) that publishes modules directly to IPFS; here's [another decentralized package manager](https://github.com/mhhf/spore) that sprung up using IPFS and Ethereum.
+
+The IPFS community has been thinking about immutable package managers for a long time. @diasdavid has a project called `registry-mirror`, which allows you to run an npm registry locally that is backed by packages retrieved from IPFS instead of NPM directly. He's written about a presentation he gave for it, [here](http://blog.daviddias.me/2015/12/08/stellar-module-management); the source code is [here](https://github.com/diasdavid/registry-mirror).
+
+On a similar note, [gx](//github.com/whyrusleeping/gx), a package manager for Go, was also mentioned in a lot of the discussions about npm and package managers, especially on [Hacker News](https://news.ycombinator.com/). In the past two weeks, the project has recieved over 1000 stars - before, there were around 50.
+
+The discussion about how to best use IPFS as a package manager is ongoing. Jump on GitHub if you have something to say; we're listening in the [FAQ](https://github.com/ipfs/faq/issues) and in [the notes repo](https://github.com/ipfs/notes/issues).
+
+### DNS outage
+
+We're using DigitalOcean for providing ipfs.io DNS. On Tuesday, March 24th, DigitalOcean DNS was hit by a [severe outage](https://www.digitalocean.com/company/blog/update-on-the-march-24-2016-dns-outage/) lasting hours, which took the public gateway at ipfs.io down. We switched to [DNSimple](https://dnsimple.com) in an ad-hoc fashion and brought ipfs.io back while DigitalOcean was still down, but this incident obviously hit us on the wrong foot a bit. We'll be working to never get taken down this way again. Here's a few things we'll do:
+
+- codified DNS zones, and tools to upload them to DNS providers
+- one or two backup DNS providers
+- monitoring and failover procedures
+
+We'll post a more detailed postmorten on our blog in the next few days.
+
+### Captain.log
+
+#### Aye, you might want to check the new js-ipfs Captain.log entry, mate!
+
+Following [js-ipfs roadmap](https://github.com/ipfs/js-ipfs/blob/master/ROADMAP.md#milestone-1---js-ipfs-on-the-browser), we’re close™ to having a workable js-ipfs version that can be used in the browser and in Node.js. This will mark a very important milestone on the IPFS project and enable a whole set of new distributed web applications to be possible. If you want to be part of this effort, check out our [Captain.log](https://github.com/ipfs/js-ipfs/issues/30#issuecomment-205884015) entry to get a full update and a list of tasks you can contribute to.
+
+### Orbit
+
+@haadcode has been working on improvements to [orbit-db](https://github.com/haadcode/orbit-db), [ipfs-log](https://github.com/haadcode/ipfs-log/) and [Orbit](https://github.com/haadcode/orbit). The message history fetching is now more stable and the UI feedback for loading messages is fixed. All this work will improve the user experience of Orbit.
+
+### js-ipfs-init
+
+`js-ipfs init` works! @noffle finished the remaining pieces this week, including CLI usage. This included a handful of [auxiliary](https://github.com/ipfs/js-ipfs/issue/91) [PRs](https://github.com/ipfs/js-ipfs/issue/96) that cascaded out of that work. This makes the `js-ipfs` init process produce IPFS repos that are compatible with go-ipfs' - this is big!
+
+#### Dictionary support for the zlib JavaScript Implementation, [`pako`](https://github.com/nodeca/pako)
+
+One of the significant contributions made this week was the addition of 'dictionary' support for `zlib` JavaScript implementation, `pako`. With this contribution, we are able to have a complete implementation of SPDY 3.1's framing layer running in the browser, the default stream muxing library used in IPFS. You can find more about this contribution in the following issue and PR discussions:
+
+- https://github.com/nodeca/pako/issues/69
+- https://github.com/diasdavid/js-libp2p-spdy/pull/6
+- https://github.com/nodeca/pako/pull/77
+
+### go-ipfs
+- @whyrusleeping wrote a tool to move content from 0.4.0 to 0.3.11 (https://github.com/whyrusleeping/levart-emit). He also discovered a file descriptor leak bug in utp causing connectivity issues, and began work on datastore performance improvements.
+
+#### `jsipfs object` cli and http-api endpoints are complete
+
+Now you can use `jsipfs object` in the same way you would use `ipfs object`. Big thanks to [Francisco Dias](https://github.com/xicombd) for leading the last miles of this goal. The complete track of the development can be found at [github.com/ipfs/js-ipfs/issues/58](https://github.com/ipfs/js-ipfs/issues/58).
+
+### Nginx metrics
+
+Our internal metrics dashboard didn't previously have HTTP request/response metrics from nginx's point of view, but only from IPFS's and [multireq](https://github.com/whyrusleeping/multireq)'s point of view. (Multireq is our v04x/v03x multiplexing proxy). Nginx itself provides finegrained metrics only through their commercial subscriptions. We're now using [mtail](https://github.com/google/mtail) to parse metrics from nginx access logs and expose them to [Prometheus](https://prometheus.io). @lgierth will also contribute the `nginx.mtail` program upstream with mtail.
+
+## Community
+
+### Upcoming talks
+
+On April 20th, IPFS will host a joint meetup with ConsenSys at MIT in Cambridge, Massachusetts. [Sign up here!](https://www.eventbrite.com/e/ipfs-ethereum-mit-meetup-tickets-24578852008)
+
+### First IPFS Meeting in NYC
+
+![Christian](009_christian.JPG)
+
+We had our first IPFS meetup in New York! It went fantastically; over 100 people came to the AWS Loft for a couple of hours to mingle, eat pizza, and hear the speakers:
+
+- @jbenet gave an introduction to IPFS and a talk about [IPLD](https://github.com/ipfs/specs/blob/master/merkledag/ipld.md).
+- [Christian Lundkvist](https://twitter.com/ChrisLundkvist) -- CTO of Consensys and author of many Ethereum applications (pictured above) -- gave an introduction to [uPort](https://medium.com/@ConsenSys/uport-the-wallet-is-the-new-browser-b133a83fe73#.fx13an2b0), an exciting new decentralized Identity system. uPort uses programs on the Ethereum Blockchain and content on IPFS to maintain identity records that are permanent, uncensorable, and self-controlled. The uPort attestation system allows third party authorities as well as peers to validate the user's information creating both a rich social fabric as well as powering solid KYC/AML systems in the financial sector.
+- Arkadiy gave an introduction to [Mediachain](https://blog.mine.nyc/introducing-mediachain-a696f8fd2035#.lh5fohuz1), a collaborative federated media metadata protocol that allows parties to make statements about creative works. The metadata statements are cryptographically signed by the contributor, timestamped in the Bitcoin blockchain, and stored in IPFS. The statements can then be looked up via perceptual search using an instance of the media itself.
+- @haadcode demo'd [Orbit](https://github.com/haadcode/orbit), a distributed p2p chat on IPFS.
+- [Chris Pacia](https://twitter.com/chrispacia) -- Lead backend developer for OpenBazaar -- spoke about the challenges of building a decentralized marketplace and the goals for OpenBazaar 2.0. The talk discussed how IPFS can help solve some key development challenges.
+
+Overall, it was a ton of fun.
+
+### Meeting with NYC Mesh
+
+@jbenet and @lgierth met with the fine folks of [nycmesh.net](https://nycmesh.net). For the past two years they've been building a community Wifi network in New York City. We had lots of great conversation about wireless mesh networking and IPFS. If you live in NYC, you should come attend their [meetups](http://www.meetup.com/nycmesh/)!
+
+### [NYC Blockchain](http://nyc.blockchainworkshops.org/)
+
+Last Monday members of the IPFS comminuty attended a [blockchain workshop](http://nyc.blockchainworkshops.org/) event held by Coala, "a collaboration between academics, lawyers, technologists and entrepreneurs who have been driving research, policy and infrastructure-building in the blockchain ecosystem for the past three years" at the New York University School of Business. @diasdavid @haad @noffle and @nginnever were in attendance as @jbenet was a part of a protocols panel, speaking on scalability and the future of blockchain technology. A recording of the event should be available on youtube in the future [here](https://www.youtube.com/channel/UC9Lmf5FfNkSmYMoxhQh5ktA).
+
+### Lisbon Research and Development Meetup
+
+![Lisbon](009_lisbon.png)
+
+[The IPFS Lisbon community had their second "Research & Development Meetup"](http://www.meetup.com/ipfs-lisbon-meetup/events/229807984/), hosted by Uniplaces (https://www.uniplaces.com). The focus was "The Distributed Web" ([Slides](http://www.slideshare.net/DavidDias11/rdm2-the-distributed-web)) and "Machine Learning + Artificial Intelligence for Recommender Algorithms", with talks by [David Dias](https://github.com/diasdavid) and [João Ascensão](https://github.com/jtascensao), respectively. If you are around Lisbon, make sure to join http://www.meetup.com/ipfs-lisbon-meetup to get notified about the next one. Resources for this talk can be found [here](https://github.com/research-development-meetup/discussion/tree/master/rdm-2).
+
+### Seattle
+
+@whyrusleeping gave a talk introducing IPFS at ta3m seattle - [Techno-Activism 3rd Mondays](https://wiki.openitp.org/events:techno-activism_3rd_mondays:seattle). Video links to come when they are posted.
+
+### BitCoin News
+
+BitCoin news had a discussion on using IPFS and Bitcoin for Decentralised Citizen Journalism. [Check it out](http://thebitcoinnews.com/decentralised-citizen-journalism-we-discuss-the-impact-of-bitcoin-and-ipfs/)!
+
+### BitDevsNYC
+
+[Christian Lundkvist](//github.com/christianlundkvist) gave a talk on IPFS at [BitDevsNYC](http://www.meetup.com/BitDevsNYC/events/229130058/). Christian works closely with IPFS at [ConsenSys](https://consensys.net/).
+
+## IPFS Meme of the Week
+
+![Hee hee](009_neo.jpg)
+
+From https://twitter.com/jplur_/status/712670265919086594. Thanks, jplur_!
+
+## Content-Type of the Week
+
+Now that we're using mtail to make better sense of nginx serving the
+IPFS-to-HTTP gateway, we can graph the frequency of content types served.
+We'll showcase interesting content types served from the gateway in the coming
+weeklies.
+
+The first Content-Type of the week is: application/x-chdr, which signifies a C source header file.
