Introduction: In the ever-evolving landscape of wireless networking, open-source solutions have gained considerable traction, offering users the freedom to customize and optimize their network infrastructure. Two prominent players in this domain are OpenWiFi and OpenWrt, each with its unique features and capabilities. In this blog post, we will delve into the similarities and differences between these two open-source wireless platforms. Similarities: Open Source Roots: Both OpenWiFi and OpenWrt share a common foundation in open-source software. This means that their source code is accessible to the public, encouraging community-driven development and collaboration. Customization and Flexibility: One of the primary strengths of both platforms is the ability to customize and tailor the software to meet specific user requirements. This flexibility allows users to optimize their wireless networks for performance, security, and functionality. Community Support: Both OpenWiFi and OpenWrt benefit from active and engaged communities. This collaborative environment enables users to seek assistance, share knowledge, and contribute to the improvement of the platforms. Differences: Purpose and Focus: OpenWiFi, being a project of the Telecom Infra Project, has a broader focus on providing a flexible and scalable framework for various wireless technologies. OpenWrt, on the other hand, primarily focuses on firmware for consumer routers and embedded devices. Development Community: While both projects thrive on community contributions, the nature of their communities differs. OpenWrt has a more established and diverse community, given its longer existence and widespread adoption. OpenWiFi, being relatively new, is still growing its user base and contributor community. Target Audience: OpenWrt caters to a broad audience, including home users, network administrators, and developers, seeking to enhance the capabilities of their routers and embedded devices. OpenWiFi, with its emphasis on telecom infrastructure, may be more appealing to industry professionals and organizations involved in the development of wireless systems. Modularity and Scalability: OpenWiFi places a strong emphasis on modularity and scalability, making it suitable for a wide range of wireless use cases. OpenWrt, while flexible, is traditionally associated with home networking and may not be as inherently scalable for large-scale infrastructure deployments. Conclusion: In the dynamic realm of open-source wireless solutions, both OpenWiFi and OpenWrt offer valuable contributions. Choosing between them depends on specific needs, preferences, and the scale of deployment. OpenWiFi, with its focus on telecom infrastructure and modularity, may be a preferred choice for industry professionals, while OpenWrt's established community and versatility make it a reliable option for a variety of users.

As these platforms continue to evolve, their features and capabilities are likely to expand, further enriching the landscape of open-source wireless networking.

I guess I should really start off by being honest and letting you know up front that there's an underlying motive for this blog, which starts with the fact that I was just reading the April 2011 issue of Discover Magazine .   As part of a review of the movie Source Code , the reviewer mentioned two films of which I was previously unaware.   One of these films was Donnie Darko . The leader on Amazon starts off saying: "During the presidential election of 1988, a teenager named Donnie Darko sleepwalks out of his house one night, and sees a giant, demonic-looking rabbit named Frank, who tells him the world will end in 28 days, 6 hours, 42 minutes, and 12 seconds."   My initial reaction was "Do I really want to see yet another film about demonic-looking rabbits?" (I've still not recovered from "the incident" ), but there are a whole bunch of reviews for this film and they all score very highly. Also, the Director's Cut version was only $13.16, so I thought "What the heck?" and ordered it. (For some reason, the Original Cut sells for $39.95, which I thought was over the top, but if you've seen both versions I'd love to hear your views as to which one is the one to see.)   But that's not what I wanted to talk to you about (grin). The other film was Primer, which was described (in Discover Magazine ) as follows: "Despite its puny $7,000 budget, Shane Carruth's 2004 cult classic stitched together one of the trippiest movie versions of time travel. Be prepared to watch it several times to decipher the convoluted time line."   Now I have to say that this one really caught my eye, because I very much enjoy stories about time travel. But when I bounced over to check it out on Amazon I saw that it had a mixed bag of reviews – some folks love it while others loath it. Also, it costs $52.98, which is a price that brings tears to my eyes (and these are not tears of happiness).   So, excluding Primer (about which I am still a little sketchy), what was your favourite time travel story of all time? I've not seen The Time Traveler's Wife so I really cannot comment on that. I really liked Millennium (the movie), although that was really more of a mystery-thriller than a time travelling tale.   Of course H.G. Wells' Time Machine is absolutely brilliant – both in book and movie form. Personally, with regard to the movie, I prefer the Original 1960s version starring Rod Taylor, but I also very much enjoyed the effects in the 2002 Remake starring Guy Pearce.   And who amongst us could forget A Sound of Thunder – the short story by Ray Bradbury, which was first published in Collier's magazine in 1952. According to the Wikipedia, as of 1984, this was the most re-published science fiction story of all time. The idea is that a hunting party from 2055 travel back into the past on a guided safari to kill a Tyrannosaurus Rex. I'm drastically simplifying this, but one of the hunters leaves the designated path and kills a butterfly – when the party returns to their own time they discover that the demise of the butterfly have triggered many changes... (Someone made a film about this, but it was so bad that I don't want to sully your eyes with a description of it here.)   Now, if we are talking about a time traveling story that (to the best of my knowledge) only ever appeared in written form, I would have to say that my all-time favourite was The End of Eternity by Isaac Asimov. This is too convoluted to go into here (you've either read it or you haven't), but I thought that everything about this book was very clever and thought-provoking – especially the twist at the end. The mystery to me is why no one ever made this into a movie ... if they did I would be queuing outside the cinema clamoring to be let in...   But I'm sure that I'm forgetting a bunch of really amazing books and films ... help me out here ... which time travelling tale would you vote "#1 Of All Time" ?

According to an entry on Wikileaks and other sources, hackers broke into a database used by pharmacists in Virginia, US last April 2009. Eight million records were deleted. The bad guys are demanding a $10 million ransom to return the data. They claim to have deleted the backups, too. One could rant about poor security practices that left the data vulnerable. But what I find appalling, assuming the claim is correct, is the apparent lack of adequate and safe backups. I really shouldn't be surprised, as many of us—way too many—do a poor job insuring there's a safe copy of our digital data archived. I hear constantly from developers who are losing weeks and months in recreating missing source code. A few years ago, a company informed me they were shutting the doors due to a fire in the engineering department that took out their source code; no off-site backups were maintained. My computer-illiterate brother has lost all of his pictures, twice, due to hard disk crashes, yet he still refuses to get serious about a simple backup solution. One would think a single bad experience would be reforming; to have had this happen twice and still not take preventative measures boggles the mind. The most important asset many companies posses is their data, whether that's customer files, source code, or accounting files. Yet in far too many you're liable to get in trouble for defacing an unimportant asset—like a desk—while the data is vulnerable to hackers, fire, or an rm "r *.* from an angry laid-off worker. Once we were told to keep an off-site backup. That is no longer good advice. We learned from Hurricane Katrina that it's possible to lose an entire city. Keep a backup a kilomile away. In this day of cloud computing that's simple and cheap. We paint our houses to preserve them. Change the oil in the car to keep it running well. Owning anything implies a level of responsibility, and that, too, is true of computers. Even a ma and pa shop needs effective backups. Your home data, those pictures, music and other records, need to be archived frequently and safely. How do you protect your data?
