The two closest things to Slack in the open source world are Mattermost and Rocket Chat. Both support all the popular features of Slack including inline code snippets (Rocket Chat even offers code highlighting), inline images, archived searchable conversations, easy sign up, web apps, desktop apps and mobile clients. Rocket Chat also includes support for Markdown, and Mattermost can import Slack user accounts and channel archives to smooth the transition.Where the two differ is in the user interface and in the backend setup (Rocket Chat uses MongoDB behind the scenes, while Mattermost uses PostgreSQL). Mattermost user interface is a bit closer to Slack, while Rocket Chat seems to have taken more inspiration from full-featured IRC clients.Both, however, are self-hosted, which means projects can get most of the advantages of Slack over IRC, but retain control of the open source tools. If the history of web services teaches anything, it's that relying on third-party services for key parts of your development infrastructure is almost guaranteed to fail in the long run.While Mattermost and Rocket Chat, along with services like IRCCloud, which piggybacks on IRC to offer a more Slack-like experience, can fulfil 90 per cent of the Slack experience, none of the them match Slack 100 per cent. Mattermost lacks an Android client (it's in the works), none of them have the amount of third-party integration that Slack offers, and none of them have the install base that Slack claims to enjoy - 1.1 million “daily average users in July last year so it said.

It's the last point that open-sourcers needs to consider. Ubiquitous install trumps everything else. With more and more developers using Slack on small teams at work (as it's intended to be used) it's natural to want to use the same tools for other projects.There is an opportunity here for open source, though.

Setting up and using Slack may be simple but extending it is not. If more developers turn to open source alternatives there will be more developers to hack on these alternatives. More momentum means more features, more cool hacks and in the end a more useful product. This is why Apache trumps Microsoft IIS, WordPress thrives while Movable Type is a memory, and Linux is the most wildly deployed operating system on the server.On the other side of the argument, lack of developer interest in alternatives is part of why Dropbox has no real open-source competitor, Google Docs continues to be more popular than open-source options, and Foss offers almost no competition to Skype.Slack may be the best choice now, but investing in open source alternatives like Mattermost or Rocket Chat is the best choice for open source coders in the long term. VMware's popped out its second update to vSphere 6.0 and addressed a long-time vAdmin gripe by adding a new web interface that doesn't rely on old-school plugins.The new VMware Host Client is an all HTML-5 affair. The new code is derived from a “Fling” VMware posted a few weeks back (Flings are useful-but-unsupported code that VMware suggests vAdmins might want to play with) and has now made it into ESX.It's still no masterpiece of usability – as the illustration at top (or here for those reading our mobile site) attests – but is notable for two reasons.

One is that VMware has remained loyal to the ancient Netscape derived NPAPI plugin standard. Moving to HTML 5 does away with that. The second is that vAdmins have often bemoaned the state of the web clients available.

The TC35661 series are highly integrated RFCMOS Bluetooth devices which support Bluetooth Classic (3.0+EDR) and Bluetooth Low Energy (LE) 4.0 and 4.2 standards. TC35661 supports the standard Bluetooth HCI interface and offers integration of stack and selected BT profiles on-chip.

Through its WIFI coexistence interface it supports the BT3.0-HS function. The devices realise an easy way to integrate Bluetooth for various industrial, medical and automotive applications. Toshiba has tested the Bluetooth interoperability extensively.

All Toshiba Bluetooth devices and software are Bluetooth Qualification Expert (BQE) qualified. The Toshiba Bluetooth® LSI TC35661SBG has been embedded - including it's SPP & BLE-GATT profile - into the Panasonic (PIDEU) module PAN1026. It is FCC/IC/CE certified.

The embedded stack and profile were Bluetooth™ SIG approved through extensive BQB (Bluetooth™ Qualification Body) tests. The module is ideal for for wireless serial applications and all kind of BLE connectivity. System developers can make use of the Serial Port Profile and hook on their selected BLE profile onto BLE-GATT through the comfortable Toshiba API interface over UART.

Dual Mode core for classic and Bluetooth 4.0 and 4.2 standards. BQE qualified hardware and software for easy Bluetooth EPL. Flexible system architectures through: HCI model Embedded profile model Stand alone model. Embedded on-chip Bluetooth stack and selected profiles for easy Bluetooth system design.

Stand alone operation for small applications is feasible without a host MCU. Ultra low bill of materials due to very few external components. Multiple programmable IO options. On-chip voltage controller and low power modes. Consumer and automotive qualification (AEC-Q100). Bluetooth® Core Spec 3.0, 4.0 and 4.2, EDR and LE support. TC35661–0XX: HCI type.

TC35661–XXX: embedded profile type. BT Class 2 support.

RX Sensitivity –91dBm (typ.). Baseband with ARM® CPU - 13 to 52 MHz. On–chip ROM, RAM, including Patch–RAM. On–chip balun, antenna switch, LNA, LDO.

The Bluetooth® HCI (host controller interface) model: the low layer stack (RF, LC, LM) runs on the TC35661SBG device (ROM or external flash memory). Through a UART or USB it is connected to an external host processor, which executes the upper Blueooth® stack (L2CAP, RFCOMM) and profiles. Beyond the upper stack the host processor runs the application software. This application processor may also run additional tasks such as middleware and multimedia functions. This concept is suitable for voice and data.

The Embedded Profile model integrates both the lower and upper stack as well as some selected profiles in the TC35661SBG (ROM or external flash memory). The UART interface carries the data of a higher layer API.

The whole Bluetooth® functionaly is managed by the Bluetooth® LSI. The host processor only handles the application data. Depending on the complexity of the application the host CPU performance requirement can be very minor. This concept is for data only. The Embedded Profile models for BT4.0 features Smart Ready (dual mode) or Smart (BLE single mode) Bluetooth® marking.
