Cracking the secret codes of Europe's Galileo satellite

Filed under
Sci/Tech

The navigational satellite, GIOVE-A (Galileo In-Orbit Validation Element-A), is a prototype for 30 satellites that by 2010 will compose Galileo, a $4 billion joint venture of the European Union, European Space Agency and private investors. Galileo is Europe's answer to the United States' GPS.

Because GPS satellites, which were put into orbit by the Department of Defense, are funded by U.S. taxpayers, the signal is free -- consumers need only purchase a receiver. Galileo, on the other hand, must make money to reimburse its investors -- presumably by charging a fee for PRN codes. Because Galileo and GPS will share frequency bandwidths, Europe and the United States signed an agreement whereby some of Galileo's PRN codes must be "open source." Nevertheless, after broadcasting its first signals on Jan. 12, 2006, none of GIOVE-A's codes had been made public.

Richard Stallman says Microsoft's Linux love-in is a ploy to 'extinguish' free software

GNU OS CREATOR Richard Stallman has slammed Microsoft's Windows 10 subsystem for Linux as an attempt to "extinguish" free software. Microsoft, a company whose ex-CEO famously slammed Linux as a "cancer", has a new found "love" for open source software, having last month released its hell-over-freezing subsystem that lets Windows 10 users run various GNU/Linux distros and software. Unsurprisingly, some are sceptical about Microsoft's new-found enthusiasm for Linux and open source software, including free software advocate, and founder of GNU OS Richard Stallman. Speaking to Tech Republic, he said Microsoft's decision to build a Windows Subsystem for Linux (WSL) amounts to an attempt to extinguish free, open source software. "It certainly looks that way. But it won't be so easy to extinguish us, because our reasons for using and advancing free software are not limited to practical convenience," he said. "We want freedom. As a way to use computers in freedom, Windows is a non-starter." "The aim of the free software movement is to free users from freedom-denying proprietary programs and systems, such as Windows. Making a non-free system, such Windows or macOS or iOS or ChromeOS or Android, more convenient is a step backward in the campaign for freedom."

Are These the Toughest Linux Operating Systems to Install?

It’s important to keep in mind that no matter the Linux operating system you choose to install, what matters is getting it onto your computer and using it. Sure, there may be benefits or drawbacks to whatever setup you pursue, but that’s just how Linux is: various by nature. What’s really important is choosing something that best suits you. If you want a high level of flexibility, then by all means, use something like Arch Linux. And if you want something more automated, that’s fine as well. It’s still Linux, after all. Read more

Qt 5.10 Alpha in testing for KDE neon

Qt 5.10 got an alpha release last week and rumours are there’s lots of interesting new stuff for Plasma developers and other parts of KDE. Packages are available in KDE neon but hidden away in the testing repository because there is inevitably some breakage. Random bits of QML such as the clock above and Kirigami seem to be unhappy. Please do test but expect breakage and fixes to be necessary. Read more
