SSDs vs HDDs



Review the 2 industry–leading data storage devices





For decades there was only 1 efficient option to keep data on a computer – working with a hard drive (HDD). Then again, this sort of technology is currently demonstrating it’s age – hard drives are actually loud and sluggish; they can be power–ravenous and frequently create a great deal of warmth during intense procedures.

SSD drives, on the contrary, are really fast, consume far less energy and they are far less hot. They provide an exciting new solution to file accessibility and storage and are years ahead of HDDs in relation to file read/write speed, I/O operation and also energy effectivity. See how HDDs stand up against the newer SSD drives.

GNU hackers discover HACIENDA government surveillance and give us a way to fight back


GNU community members and collaborators have discovered threatening details about a five-country government surveillance program codenamed HACIENDA. The good news? Those same hackers have already worked out a free software countermeasure to thwart the program.

According to Heise newspaper, the intelligence agencies of the United States, Canada, United Kingdom, Australia, and New Zealand, have used HACIENDA to map every server in twenty-seven countries, employing a technique known as port scanning. The agencies have shared this map and use it to plan intrusions into the servers. Disturbingly, the HACIENDA system actually hijacks civilian computers to do some of its dirty work, allowing it to leach computing resources and cover its tracks.

But this was not enough to stop the team of GNU hackers and their collaborators. After making key discoveries about the details of HACIENDA, Julian Kirsch, Christian Grothoff, Jacob Appelbaum, and Holger Kenn designed the TCP Stealth system to protect unadvertised servers from port scanning. They revealed their work at the recent annual GNU Hackers' Meeting in Germany.



We must fight the political battle for an end to mass surveillance and reduce the amount of data collected about people in the first place. On an individual level we have to do everything we can to thwart the surveillance programs that are already in place.

No matter your skill level, you can get involved at the FSF's surveillance page.

Ethical developers inside and outside GNU have been working for years on free software that does not keep secrets from users, and programs that anyone can review to remove potential vulnerabilities. These capabilities give free software users a fighting chance against surveillance. Now, our community is turning its attention to uncovering and undermining insidious programs like HACIENDA. Free software and its ideals are crucial to putting an end to government bulk surveillance.

Share this news with your friends, to help make people aware of the importance of free software in fighting bulk surveillance.

Jacob Appelbaum of the TCP Stealth team gave a remote keynote address at the FSF's LibrePlanet conference this year. Watch the recording of "Free Software for freedom: Surveillance and you."

Richard Stallman's TEDx video: "Introduction to free software and the liberation of cyberspace"

Are you in search of an easy way to explain to others what free software is and why it matters? Or are you perhaps wondering why you yourself should be concerned about computer-user freedom? If your answer is yes, then this TEDx talk by FSF president Richard Stallman (RMS) is what you're looking for!

RMS was invited to give a TEDx talk at "FREEDOM (@ digital age)" in April and took the opportunity to explain the fundamentals of the free software movement to the general public. In this speech, RMS introduces the issue and makes the stakes clear; he explains what a computer is and who controls it, what the various implications of free software and of proprietary software are for you, the user, what you can do to stop being a victim, what the obstacles to computer-user freedom are, and how you can make a difference.
The TEDx talks are "designed to help communities, organizations, and individuals to spark conversation and connection through local TED-like experiences." At these events, screenings of videos, like this one, "or a combination of live presenters and TED Talks videos — sparks deep conversation and connections at the local level."
We hope you share the recording, to help raise awareness and inspire conversations and connections in your own circles, and introduce a friend, loved one, or acquaintance, to this "first step in the liberation of cyberspace."
If you watch any TEDx talks on YouTube, please remember to use a free program like youtube-dl instead of your browser, because watching YouTube in your browser requires proprietary JavaScript.
Many thanks to Théo Bondolfi, François Epars, Florence Dambricourt, and the TEDxGeneva core-team for making this speech possible. Thank you to Ynternet.org and HEG-GE for hosting and supporting the event, and to Sylvain & Co., La Belle Bleue, and Jus de Fruits Suisses, ProLibre, and the Fondation Emilie Gourd, Piguet Galland & Cie., Lifelong Learning Programme, Hes.so Genève, My Big Geneva, and Smala for their support.
Sincerely,
Jeanne Rasata
Assistant to the President
P.S. RMS does not draw a salary from the FSF, but your donations do support the coordination of events and videos like this. We'd love to produce more introductory videos. Can you donate $25 today?

GNU Radio controls the ISEE-3 Spacecraft


The ISEE-3 spacecraft
An original drawing of the ISEE

The International Sun-Earth Explorer-3, or ISEE-3, was launched in 1978 by NASA to monitor activity on the sun. After three years of observation, NASA repurposed the satellite, which soon became the first spacecraft to visit a comet. The mission ended in 1999, when NASA abandoned ISEE-3 to orbit the Sun, despite the fact that twelve of the satellite's thirteen instruments were still working.

In 2008, when it was discovered that the satellite was still transmitting a signal and would fly close to Earth, NASA realized that they no longer had the funding or equipment to reinitiate contact. So a volunteer group of scientists, programmers, and engineers organized the ISEE-3 Reboot Project, which was crowd-funded with over $150,000 in donations, and set out to contact the spacecraft, fire its engine, and bring it closer to Earth to resume its original mission.

To do this, the group turned to GNU Radio, a free software toolkit for implementing software-defined radios and signal processing systems. Modifying the software to communicate in the 1970s satellite protocol, members of the reboot project were able to gain access to the spacecraft and fire its thrusters in early July, and will soon attempt to move the satellite into an orbit close to Earth.

You can support GNU Radio by making a donation through the FSF's Working Together for Free Software Fund. To get more involved, attend the annual GNU Radio Conference, to be held this year between September 15th and 19th in Washington, D.C.

The successes of the ISEE-3 Reboot project demonstrate the importance of developing, maintaining, and promoting free software. With dozens of contributors and thousands of users, GNU Radio is written to be shared, learned, and improved by anyone, anywhere -- unlike the lost proprietary communications equipment used by NASA.

This is the second time we've lauded the use of free software for space exploration in the last two years. Read our 2013 blog post about the choice of GNU/Linux as the operating of the International Space Station.

"This openness to inquiry, collaboration, and 'standing on the shoulders of giants' is at the heart of all science," wrote John Gilmore, a founding member of the GNU Radio project, in an email to the FSF. "The GNU Project has institutionalized those principles in a vast community of software authors and users. And GNU's legalized freedom and sharing [...] enable many people to use it and contribute to it -- such as these volunteers."
