Building an Non-Wired Network for Pueblos? 60

Posted by Cliff from the wireless-networks-in-non-urban-settings dept.
wsxian asks: "We recently received a large grant to install a wireless high speed Internet system for our entire Pueblo here in the State of NM. This would encompass about 150 homes and the range from a central point would be no more than 6 miles, but there are hills, valleys and trees so line of sight is not an option unless we decide to drop homes. I welcome any suggestions for technology to look at, what to avoid, security concerns- and most important for us what companies to avoid. If any of you have had real life experience with doing such a scaled project like this, please give your input!"

Questions for a P2P Downloading Panel Discussion? 63

Posted by Cliff from the stuff-you-wanna-know dept.
George P. Burdell asks: "On April 5, Georgia Tech's Honor Advisory Council will host a panel discussion between opposing sides of the P2P downloading issue. Among other panel members, a representative from the RIAA has agreed to attend the event. The discussion is intended to raise the level of awareness of students who may think they know all they need to know about the issue. What are some of the pressing questions the tech community has for panel members on both sides of the issue?"

Agile Methods in System Administration? 61

Posted by Cliff from the practices-in-motion dept.
sta asks: "Agile methodologies focusing on development techniques and approaches abound, many of which at the very least give food for thought. I have been in constant discussion with our dev manager about agile approaches and their extension to the systems administration world. Can agile methods and the agile mind set be applied to the systems administration world? Does systems administration rely on policy and procedure for it's integrity and reliability or is that just an ingrained habit? There appear to be a number of administrative tools that claim agility but are there any established agile methodologies?"

Which Linux Certification? 93

Posted by Cliff from the more-letters-at-the-end-of-your-name dept.
dirvish asks: "I am trying to break into the Linux Server Administration field so I have been doing quite a bit of studying lately. I figured while I am studying the subject I might as well work towards a related certification. I am leaning towards the Linux Professional Institute Certification. Other certifications I am considering are CompTIAs Linux+ and Red Hats RHCE. So which Linux certification is the best? I would say Red Hat is the most reputable of these three but I am concerned that their certification might be too Red-Hat-centric, and I don't want to be locked into one distro. Which one is the easiest/cheapest to obtain? Which is the mostly highly regarded in the industry? Are there others that I missed?"

Google's X Files Vanish 407

An anonymous reader writes "News.com reports that Google's latest technology experiment paid tribute to Apple Computer, but the Mac OS X-themed version of the search king's Web site was taken down a day after its debut. Though that particular page was taken down, there is a screenshot here displaying how the icons were magnified as the mouse hovered over them."

Teaching Computer Lit. in Developing Countries? 33

Posted by Cliff from the non-physical-reading-material dept.
Pro777 asks: "I am a US Peace Corps volunteer currently teaching 'Computer Studies' at a High School in the Republic of Samoa, in the South Pacific. Anyways, myself and other IT teachers are having a difficult time finding a good digital textbook to teach basic skills such as basic computer architecture, word processing, and using spreadsheets. Real textbooks are cost prohibitive, and a lot of what is found is too high level for our students. Any suggestions?"

Clash of the GPL and Other IP Agreements? 530

Posted by Cliff from the grabby-aren't-they dept.
Daimaou asks: "A situation I'm involved in at work has raised some questions regarding the GPL vs. IP agreements. When I started working for my employer several years ago I signed an IP agreement that states anything I think while working for them is theirs, as well as anything I've ever thought in the past if it enters their building; dumb, but I needed a job." To make a long story short: Daimaou wrote some code derived from GPLed sources. Now his company wants to take control over what he's written. IP agreements aside, this sounds like a GPL violation since the company's IP can't override IP already established by the original GPLed code. Daimaou also says the company is trying to patent at least some of the code. Is there anything Daimaou, or anyone else for that matter, can do to get the company to cut short their plans and play fair with IP that obviously doesn't belong entirely to them?

IAS/RADIUS Implementation in a Coffee Shop? 63

Posted by Cliff from the non-free-loitering dept.
noyler asks: "I've been asked to decide on the best way for metering a 'free' wireless network at a local coffee shop. Here's the scenario: currently, local college students come to the coffee shop, grab a cup of coffee, and then spread out like it's a study hall for 6 to 10 hours at a time and use the free internet. The coffee shop loves this, but it's getting really crowded for the other customers that just come in for some coffee and have nowhere to sit. The management wants to implement a system that, upon buying a drink, grants a time-limited connection for that customer of 3 or 4 hours. If the customer wants more access, another drink will need to be purchased. The store network is a simple cable modem with wireless access point attached right now. After implementation, customers should be prompted for a username/password (which can come from his or her receipt) and then have access to the 'net. One limitation is that the customers should not have to install any third-party software to use it--no window for software corruption liability that way. The customer base is mostly Windows with an ever-growing number of Mac users as well. What are some good ideas for doing this? I've considered RADIUS, or some kind of portal software, but don't see any clear answers. Any suggestions for software to use?? The coffee shop is very low budget, so cheap hardware and free software would be best!"

File Systems for Electronic Surveillance Devices? 136

Posted by Cliff from the discrete-audio-data-storage dept.
An anonymous reader asks: "A friend recently discovered that her vehicle had been bugged by the police (for reasons I won't go into here). It seems the set-up had been wired into the car's electronics, so that whenever the car was going the microphones were recording the occupants' conversations. Unfortunately I didn't get to see everything she recovered, as she was a bit exuberant in her removal and disposal. However, I have been given a 20G Fujitsu notebook hard drive and some kind of audio processing chip from a manufacturer by the name of Topoint, and have been asked if I can examine the contents. You can read on to hear about my efforts so far, but I have several questions: If the surveillance device came from a vendor, what kind of file system might they use, and if - as I suspect - it is encrypted, do I have any options other than writing zeros over the drive and putting it to less controversial use?"

Flickering Curiosity? 251

Posted by Cliff from the refresh-detection dept.
N8F8 writes "Why do some people see monitor flicker more readily than others? I happen to be one of the lucky folks who can spot a 60Hz monitor from across the room. Most people seem oblivious to this flicker. Other people can only see it in their peripheral vision. I tried researching an answer and I stumbled on plenty of information about something called 'Critical Fusion Frequency'. There even appears to be quite a bit of research into this phenomena but I couldn't find much information on why flicker perception varies so greatly. Can anyone shed some (flicker-free) light on this?"

Automated CD/DVD Archival? 75

Posted by Cliff from the a-complete-backup-system dept.
An anonymous reader asks: "Our department used to use a Cedar Technologies Desktop CD-R Publisher for fully automated backup of data (~2 CDs per day) controlled by a Linux PC. The publisher just broke and we are looking into a new backup solution to automatically burn and print CDs or DVDs. Solutions for CD/DVD duplication are available for Windows and Mac (for example: Primera and Rimage [which acquired Cedar in 2000]) but not for Linux. While a Mac would be OK, none of the manufacturers seems to offer scriptability or a command line interface which is essential for our task. Tape and HD backup are not an option - the data is already mirrored on RAIDs. Has anyone set up a similar archival system using Linux?"
Patents

Understanding (and Avoiding) Software Patents? 72

Posted by Cliff from the patent-infringement-mine-sweeping dept.
An anonymous reader asks: "I'd like to write some Free backup software, but this area is mined with patents. I downloaded one and tried to understand it, but the 'claims' section (arguably the most important part) is made up of utterly incomprehensible patentese, and I can't afford to hire a patent attorney to help me understand it. Are there any free or cheap ways to learn enough about patents to understand them, so I can figure out exactly what is patented and therefore avoid it?"

High-Capacity PCMCIA Drives for Backup? 65

Posted by Cliff from the will-technology-catch-up-with-our-data-needs dept.
jspivack asks: "My dad is looking for a very portable backup system for his laptop. He's tired of going without his apps and data for days on end when it goes down - and since it's a laptop, anything from trackpad to screen to USB port problems means sending the whole computer in for repair. I figured this would be the perfect use for a high-capacity PCMCIA hard drive: he could just keep it in his slot and make a nightly carbon-copy of his main HD. No external messiness to deal with. And if his machine goes down, he just pops out the drive and pops it into a loaner machine. The problem is, I've googled around and it would seem that Toshiba only makes PCMCIA drives in a 5GB flavor, despite the fact that they have 1.8" drives going to 60GB. Have I missed some other high-capacity (>=20Gb) -internal- PCMCIA drives (Google's not perfect, and neither am I)? Does anyone know if I could buy a 5GB PCMCIA drive and a larger 'embedded' drive and just swap the larger drive itself into the PCMCIA interface portion of the smaller drive? I know it would be taller, but both of his slots are open. Does anyone know if there are technological barriers to this hack?"

Anatomy of a Successful Enterprise Linux Distro? 217

Posted by Cliff from the what-pieces-do-corporations-drool-over dept.
phenix asks: "With the new release of Novell Linux Desktop, and the upcoming release of Sun JDS3, I am curious to hear how these two suites, and their underlying enterprise infrastructures (JES and OES) compare. Specifically, I am interested in their ease of management/deployment in these areas: directory services, productivity (office) applications, centralized application serving, centralized document storage, groupware, and remote application installation. All of these, of course, without the use of Windows products like Exchange and Windows technologies like Active Directory. Is there a better alternative?"
