  • Spotlight : Alwaysdata.com the company behind Piwik.org web hosting [Interview]

    11 avril 2013, par matt — About, Community

    Piwik is the result of the work of many talented individuals and companies. Today we’d like to showcase Alwaysdata.com, the awesome web hosting company providing managed hosting for all Piwik.org websites and services.

    I recently met and asked a few questions to Cyril, co-founder of Alwaysdata.com and Piwik core developer. Learn more in the interview below !

    What is Alwaysdata ?

    We are a French web hosting company created in 2006. If you need to host a website — a Piwik installation, for example — or even your domains/emails, we provide infrastructure and maintenance services.

    Who are your customers and what kind of work do you do ?

    We have several types of clients :

    • Individuals who need hosting for their personal site and who benefit from storage space with direct SSH access.
    • Web agencies who need hosting for their clients’ sites.
    • The largest customers, often on dedicated servers, for hosting their site/infrastructure.

    Our work falls into three categories :

    1. Support (via administration, telephone, Twitter, IRC, etc.)
    2. Development (in Python), primarily to add new features
    3. System administration, either for maintenance (e.g. adding servers), or for preparing new features

    What sets Alwaysdata apart from the large web hosting competition ?

    Two things :

    • Availability. We are a small team and often know our customers quite well. We are all on IRC, so you can contact us directly if you need any assistance.
    • Features. We are halfway between traditional web hosting and the cloud, combining the advantages of both.

    Are you using Piwik internally or with customers ? If so, how are you using Piwik ?

    All of our customers can view statistics for their sites via our global Piwik installation, without having to configure anything.

    To provide these analytics reports to our customers, we implemented import of the raw access logs in Piwik. The Log import toolkit is now a feature included in Piwik.

    What is the next big thing for Alwaysdata ?

    We are going to upgrade our pricing : instead of fixed costs, each of our clients will now pay exactly what they consume. This allows our clients the benefit of a very high quality service for the lowest possible price.

    We are also going to add native support for more technologies : Java, Node.js, ZeroMQ, etc.

    Thank you for your time and all the best to Alwaysdata for the future !

    Note from Matt, Piwik founder : Cyril and the team at Alwaysdata.com have been consistently great in their system administration work for Piwik.org services, providing a fast and reliable web hosting experience with top notch support and security practises. They also handled the migration of all services from our old servers with total piece of mind.

    Alwaysdata contributed to Piwik the popular Log Analytics toolkit. They are great software developers and system administrators with a passion for their work. Since 2006, they have been maintaining optimized hosting services for the entire web infrastructure (websites, domains, emails, databases, etc.), from the simplest to the most exotic. We do recommend their managed hosting services.

  • Availability of WebM (VP8) Video Hardware IP Designs

    10 janvier 2011, par noreply@blogger.com (John Luther)

    Hello from the frigid city of Oulu, in the far north of Finland. Our WebM hardware development team, formerly part of On2 Technologies, is now up-to-speed and working hard on a number of video efforts for WebM.

    • VP8 (the video codec used in WebM) hardware decoder IP is available from Google for semiconductor companies who want to support high-quality WebM playback in their chipsets.
    • The Oulu team will release the first VP8 video hardware encoder IP in the first quarter of 2011. We have the IP running in an FPGA environment, and rigorous testing is underway. Once all features have been tested and implemented, the encoder will be launched as well.

    WebM video hardware IPs are implemented and delivered as RTL (VHDL/Verilog) source code, which is a register-level hardware description language for creating digital circuit designs. The code is based on the Hantro brand video IP from On2, which has been successfully deployed by numerous chipset companies around the world. Our designs support VP8 up to 1080p resolution and can run 30 or 60fps, depending on the foundry process and hardware clock frequency.

    The WebM/VP8 hardware decoder implementation has already been licensed to over twenty partners and is proven in silicon. We expect the first commercial chips to integrate our VP8 decoder IP to be available in the first quarter of 2011. For example, Chinese semiconductor maker Rockchip last week demonstrated full WebM hardware playback on their new RK29xx series processor at CES in Las Vegas (video below).


    Note : To view the video in WebM format, ensure that you’ve enrolled in the YouTube HTML5 trial and are using a WebM-compatible browser. You can also view the video on YouTube.

    Hardware implementations of the VP8 encoder also bring exciting possibilities for WebM in portable devices. Not only can hardware-accelerated devices play high-quality WebM content, but hardware encoding also enables high-resolution, real-time video communications apps on the same devices. For example, when VP8 video encoding is fully off-loaded to a hardware accelerator, you can run 720p or even 1080p video conferencing at full framerate on a portable device with minimal battery use.

    The WebM hardware video IP team will be focusing on further developing the VP8 hardware designs while also helping our semiconductor partners to implement WebM video compression in their chipsets. If you have any questions, please visit our Hardware page.

    Happy New Year to the WebM community !

  • Restoring corrupted video after recovery

    22 août 2019, par Harold.Demure

    I have recently recovered the content of an old drive of mine using photorec.

    To my surprise, photorec recovered a lot of files with non-video extensions (.sqlite, .apple, .pdf, .torrent...) that contain fragments of video. I can see these fragments only using mplayer/mencoder (quicktime and vlc cannot). Some of the files are even hundreds of megabyte large, but mplayer only shows me a few seconds of the video.

    Is there any script/data carving tool that I can use to see if I can recover more video fragments from these files ? I am not afraid of trying solutions that require some coding or manual inspection (e.g., search for headers via hex editors).

    Thank you for your help, any suggestion is highly appreciated.
    Harol.
