Dreamcast Operating Systems
16 septembre 2010, par Multimedia Mike — Sega DreamcastThe Sega Dreamcast was famously emblazoned with a logo proudly announcing that it was compatible with Windows CE :
It’s quite confusing. The console certainly doesn’t boot into some version of Windows to launch games. Apparently, there was a special version of CE developed for the DC and game companies had the option to leverage it. I do recall that some game startup screens would similarly advertise Windows CE.
Once the homebrew community got ahold of the device, the sky was the limit. I think NetBSD was the first alternative OS to support the Dreamcast. Meanwhile, I have recollections of DC Linux and LinuxDC projects along with more generic Linux-SH and SH-Linux projects.
DC Evolution hosts a disc image available for download with an unofficial version of DC Linux, assembled by one Adrian O’Grady. I figured out how to burn the disc (burning DC discs is a blog post of its own) and got it working in the console.
It’s possible to log in directly via the physical keyboard or through a serial terminal provided that you have a coder’s cable. That reminds me– my local Fry’s had a selection of USB-to-serial cables. I think this is another area that is sufficiently commoditized that just about any cable ought to work with Linux out of the box. Or maybe I’m just extrapolating from the experience of having the cheapest cable in the selection (made by io connect) plug and play with Linux.
Look ! No messy converter box in the middle as in the Belkin case. The reason I went with this cable is that the packaging claimed it was capable of up to 500 Kbits/sec. Most of the cables advertised a max of 115200 bps. I distinctly recall being able to use the DC coder’s cable at 230400 bps a long time ago. Alas, 115200 seems to be the speed limit, even with this new USB cable.
Anyway, the distribution is based on a 2.4.5 kernel circa 2001. I tried to make PPP work over the serial cable but the kernel doesn’t have support. If you’re interested, here is some basic information about the machine from Linux’s perspective, gleaned from some simple commands. This helps remind us of a simpler time when Linux was able to run comfortably on a computer with 16 MB of RAM.

How can I concatenate these two video files that are in different formats with ffmpeg ?
11 juin 2018, par jaybersFile s.mp4 is created from a photo and a silent audio track was added in.
File r.mp4 was created using the built in video record on an android tablet.I would like to try to match s.mp4 to r.mp4 so that they can concatenate (s then r). Right now, the time base seems off and it plays audio from the r.mp4 but never shows the video. It it always shows the video from s.mp4. I was able to match the tbn of 90k by using
-video_track_timescale 90k
but I did not know how to match the tbc. It is 180k on one and 59.94 on the other.Probe for s.mp4
./ffprobe s.mp4

Piwik SSO options and why is it useful ?
8 novembre 2017, par Piwik Core Team — PluginsBored with typing again and again different logins and passwords for each service you have access to ? Would you like to add hundreds or thousands of users with different roles to your Piwik at once ? Would you like to save time and effort of managing your users while increasing the security in your business ? Guess what, Piwik has come up with great features to do just that.
But what is a SSO ?
Before introducing you to new Piwik features, let me explain what a SSO is.
SSO is the acronym for Single Sign On. As its name suggests this authentication process allows a user to access multiple applications with one set of login credentials.Advantages of using a SSO are numerous :
- improving security, for example when an employee is leaving your company, how can you check that all his credentials have been removed ?
- reducing employees time-wasters such as having to enter logins/passwords each time.
- providing a centralized database for administrators. They can then easily manage permissions of all employees saving them heaps of time.
- reduces support costs related to authentication / accounts management.
In order to provide SSO options, two Piwik plugins have been developed and are available on the marketplace :
SAML
SAML stands for “Security Assertion Markup Language”, it is a standard in order to exchange authentication and authorization between an identity provider (OneLogin, Okta, Ping Identity, ADFS, Google, Salesforce, SharePoint…) and a service provider.
An identity provider is an online service that authenticates users on the Internet by using security tokens.Are you wondering if your business or organization is using any of these providers ? We recommend to ask your operations team or sysadmin.
At InnoCraft, we developed a plugin in order to allow SSO with SAML for Piwik. It can ensure consistent access control across the enterprise and external providers, potentially reducing support costs related to authentication and accounts management.
The installation process is straightforward. All you need is to get the SAML premium feature from the marketplace. Once installed, you will access the SAML configuration interface through the admin where you can configure various settings :
- SAML Status
- Identity Provider (Entity ID, SSO endpoint info, Public x509 certificate)
- Just-in-time provisioning and Mapping attributes
- Access Synchronization
- Advanced settings
From there you will need to follow our detailed documentation to have it up and running :
https://piwik.org/docs/login-saml/.
Once finished, you will then be able to use SAML to authenticate to your Piwik account :As all premium features, SAML is eligible to a 30-day period money back guarantee, so do not hesitate to have it a try.
LDAP
LDAP stands for Lightweight Directory Access Protocol. As its names implies LDAP is a directory, hosted on a server, which organizes the data about people in your company.
Thanks to the LDAP plugin, Piwik can be connected to your LDAP infrastructure and then use all its power in order to give each individual an access with different rights according to their needs.Let’s say that you have 1,000 employees within a company and they all need right now an access to the analytics reports in Piwik with different roles. This is what LDAP can do.
Moreover if your business or organization is already using LDAP, we recommend using the LDAP connector for Piwik for better security, to stop wasting time of your users and sysadmins, and to reduce the costs related to account management.
You understood it well. LDAP is a plugin which saves a LOT of time within an organization. Here is a preview of the settings part :
LDAP has been developed by the Piwik core team and is available as a Free plugin on the marketplace.
If you are surprised by the possibilities that Piwik is offering in terms of plugins, the good news is that many other plugins are waiting for you on the marketplace. Check out our premium marketplace which offers state-of-the-art plugins to get the most out of Piwik.
And if you are a developer feel free to create your own plugin, a detailed documentation is available at : https://developer.piwik.org/guides/getting-started-part-1.
