Ask Slashdot: Best Computer For a 7-Year Old? 423

Posted by timothy from the better-than-an-easy-bake-oven dept.
First time accepted submitter Boldizar writes "My son turns seven next month and I'd like to buy him a cheap computer. I'm looking for the Slashdot hivemind opinion on what would be the best computer for a child. I'm looking for a computer that will teach him basic computer literacy, and hopefully one wherein the guts are a bit exposed so that he can learn how a computer works rather than just treating it like a magic object (i.e., iPad) – but that would still keep him interested and without leaving him behind in school. For the same reason, I prefer a real keyboard so he can learn to type. I don't know enough about computers to frame the question intelligently. Perhaps something in the $300 range that would be the computer equivalent of an old mechanical car engine? Another way to think about it: I'm looking for the computer equivalent of teaching my son how to survive in the forest should the zombie apocalypse ever come."

Ask Slashdot: How To Begin Work In IT Freelancing? 140

Posted by Soulskill from the do-not-work-on-relatives'-computers dept.
king.purpuriu writes "I'm a computer science high school student, and I'm looking for some work in IT freelancing. I have had a interest in computers and programming for a while, and I began learning on my own before high school. I would like to gain some experience (e.g. what the bulk of the jobs in various markets require, various technologies/frameworks and their usage) and possibly make some money on the side (not expecting too much; at this point, any non-negative amount will do). Key areas are web development, app programming and scripting. What solutions do you recommend? Any tips or tricks of which I should be aware? How should I deal with payment (in terms of fees and commissions; I'm from European country), and what type of work should I seek out? I would also be willing to do some small stuff for free in order to gain experience (small, static sites, small scripts, etc.)."

Ask Slashdot: Hackable Portable Music Player For Helicopters? 158

Posted by timothy from the everyone-should-just-learn-to-hum dept.
First time accepted submitter mrhelio writes "I work for a medium-sized helicopter company; we mainly fly tourists around on sightseeing flights. My company needs help finding a hacker-friendly portable music player for our helicopters. We have a problem with our onboard music players — mostly because it is an obsolete terrible design. The manufacturer has made an updated model, but it's basically the same obsolete design with the same terrible software and user interface. We are worried about spending $1000 per unit on these because the manufacturer will eventually stop making replacement units and then we will be force to buy upgrades for our entire fleet again and get everything recertified. (Any piece of equipment hard mounted in a commercial aircraft has to be certified by the FAA and it takes a lot of paper work, time and money for that to happen.) So we have a new plan: get portable music players like iPods, and plug those into the aux input in the intercom system. We need something that has nine hours of battery life, can hold at least three hours of music, and has remote control options for start, stop, volume, and selecting tracks and playlists, and a display that is visible in bright and sunny as well as dark conditions. The remote control option is the toughest part to find. The pilots need to be able to control the music without taking their hands off the flight controls for safety reasons. There are buttons and toggle switches already designed into the flight controls for these kind of purposes and we have mechanics/ engineers that can wire it all together, but the music player has to support the remote interface in the first place. Our first choice would be to give each pilot an iPod, but Apple is notoriously anti-hacking and anti-open source, plus you have to pay them ridiculous licensing fees to get access to their USB interface. So we are looking for a manufacturer that is open source / hacker friendly and makes something that meets our needs. Do you know of anything that would work for us? Maybe something that runs Rockbox? Should we just break down and design something from scratch like the Butterfly MP3 player?"

Ask Slashdot: How Would You Fix the Linux Desktop? 1154

Posted by Soulskill from the solid-color-rectangles dept.
itwbennett writes "Slashdot readers are familiar with the Torvalds/de Icaza slugfest over 'the lack of development in Linux desktop initiatives.' The problem with the Linux desktop boils down to this: We need more applications, and that means making it easier for developers to build them, says Brian Proffitt. 'It's easy to point at solutions like the Linux Standard Base, but that dog won't hunt, possibly because it's not in the commercial vendors' interests to create true cross-distro compatibility. United Linux or a similar consortium probably won't work, for the same reasons,' says Proffitt. So, we put it to the Slashdot community: How would you fix the Linux desktop?"

Ask Slashdot: What's Your Take On Stand-Up Desks? 347

Posted by timothy from the desks-that-won't-rat-under-pressure dept.
An anonymous reader writes "I work at a non-profit that doesn't have the resources to automatically bend to each and every whim. However, I've been told that I can't use a cardboard box to put my computer on, for OSHA and fire prevention reasons. So the choice is, sit down for nine hours each day or else get a standup desk to the tune of 500 bucks or more. Is this worth it? Can I make one myself? Anything to know before I get in deep?" There are lots of home-grown stand-up desks out there (search IKEA Hackers for "stand-up desk" if that's your aesthetic leaning), and some ready-made ones from plainish to very expensive. If you've used a stand-up desk, what are your thoughts?

Ask Slashdot: Dealing With Disabilities In the Workplace? 292

Posted by timothy from the getting-a-handle-on-things dept.
mpol writes "The job market can be hard right now, depending on your background and location. Having a disability makes things even more interesting. Seven years ago I suffered from a psychosis, and I was diagnosed with schizophrenia. I have been recovering quite well, and last year I started searching for a paying job. I found one, but it didn't turn out to be the right place, so I'm back at my volunteer job as web developer. My current workplace is quite unique, as there are several people who have had a psychosis in the past, or have been diagnosed with autism. When I look at myself I know that I have some things that will always play a role: I'm very sensitive to the atmosphere in the workplace for example. I also need clear communication, more so than other people. Furthermore, a workweek of maybe 20-25 hours is the max for me. I tried self-employment, but motivation and discipline are a bit hard to come by, and it's not something that will work for me long-term. In theory it's perfect, in practice not so much. I'm not sure what my short-term future will look like, and for this year I'm quite happy where I am, but next year I might go searching for a salaried job again. I'm wondering if there are more people on Slashdot who have a job in ICT, or are seeking one, and also have disabilities. How did you land at your job, and what issues do you run into in daily practice?"

Ask Slashdot: Ad-Hoc Wireless Mesh Network For Emergency Vehicles? 200

Posted by timothy from the why-not-use-smoke-signals? dept.
First time accepted submitter Texaskilt writes "I am looking to put together a mobile mesh network for my volunteer fire department and would like some recommendations from the Slashdot crowd. Ideally, the network would consist of cheap wireless routers (Linksys WRT-type) mounted on each vehicle. From there, tablets or other wireless devices could connect to the router. When the vehicles are in the station, the routers would auto-connect to the WiFi network to receive calls for service and other updates. When out on a call, the router would form an ad-hoc network with other vehicles on the scene. If a vehicle came into range of an Internet 'hotspot,' it would notify other vehicles and become a gateway for the rest of the 'ad-hoc' networked vehicles. I've looked at Freifunk for this, but would like some other options. Recommendations please?"

Ask Slashdot: Keeping Personal Tech Cool In Extreme Heat? 165

Posted by timothy from the we'd-like-to-know-in-middle-texas-too dept.
An anonymous reader writes "I live in the Middle East. Summer temperatures occasionally reach 60C/140F, well over the operating specs for most consumer tech. Quite a number of work and residential compounds are secured, prohibiting everything from computers to cameras to phones to USB sticks to car remote controls. When I know that I'm visiting one of those compounds, I end up leaving all the tech I can at home or in the office, and only bringing a cell phone, and leaving it in my car. However, "only a cell phone" has quickly morphed into "only two cell phones, a car MP3 player and remote, and .... ooh, shiny... a new tablet... and an electric razor just in case I have to touch up before a party in a compound." I'm wondering what kind of technologies we have for keeping all this tech cool for four hours in the car. Overnight events might last longer, but won't be as hot."

Ask Slashdot: Is the Rise of Skeuomorphic User Interfaces a Problem? 311

Posted by Soulskill from the add-to-dictionary dept.
An anonymous reader writes "The evolution of user interface design in software is a long one, and has historically tracked the capabilities of computers of the time. Early computers used batch processing which, is mostly unheard of today, and consequently had minimal human interaction. The late 60s saw the introduction of command line interfaces, which remain popular to this day, mostly with technical users. Arguably, what propelled computer use to what it is today is the introduction of the ubiquitous graphical user interface. Although graphical interfaces have evolved, in principle they have remained largely unchanged. The resurgence of Apple saw the rise of skeuomorphic graphical user interfaces, which are now starting to appear on Linux. Are skeuomorphic designs making technology accessible to the masses, or is it simply a case of an unwillingness to innovate and move forward?"

New submitter malcus writes "My father was hit by scammers the other day and even though he has handed over all computer service tasks to me they were able to sweet-talk him into: (1) Running some 'checks' to confirm the 'grave situation' that his computer was heading for (bad). (2) Start some remote-control program (worse). (3) Giving them his social security number (terrible). When they asked him for his credit card information he stopped and is now probably expecting them to call again. Meanwhile I have told him to dump the computer in holy-water or aqua regis and cut the internet cable. I am heading over to his place later and wonder what measures I should take."

Ask Slashdot: How Did You Become a Linux Professional? 298

First time accepted submitter ternarybit writes "By 'Linux professional,' I mean anyone in a paid IT position who uses or administers Linux systems on a daily basis. Over the past five years, I've developed an affection for Linux, and use it every day as a freelance IT consultant. I've built a breadth of somewhat intermediate skills, using several distros for everything from everyday desktop use, to building servers from scratch, to performing data recovery. I'm interested in taking my skills to the next level — and making a career out of it — but I'm not sure how best to appeal to prospective employers, or even what to specialize in (I refuse to believe the only option is 'sysadmin,' though I'm certainly not opposed to that). Specifically, I'm interested in what practical steps I can take to build meaningful skills that an employer can verify, and will find valuable. So, what do you do, and how did you get there? How did you conquer the catch-22 of needing experience to get the position that gives you the experience to get the position? Did you get certified, devour books and manpages, apprentice under an expert, some combination of the above, or something else entirely?"

Ask Slashdot: Best *nix Distro For a Dynamic File Server? 234

Posted by timothy from the when-birdwatching-goes-too-far dept.
An anonymous reader (citing "silly workplace security policies") writes "I'm in charge of developing for my workplace a particular sort of 'dynamic' file server for handling scientific data. We have all the hardware in place, but can't figure out what *nix distro would work best. Can the great minds at Slashdot pool their resources and divine an answer? Some background: We have sensor units scattered across a couple square miles of undeveloped land, which each collect ~500 gigs of data per 24h. When these drives come back from the field each day, they'll be plugged into a server featuring a dozen removable drive sleds. We need to present the contents of these drives as one unified tree (shared out via Samba), and the best way to go about that appears to be a unioning file system. There's also requirement that the server has to boot in 30 seconds or less off a mechanical hard drive. We've been looking around, but are having trouble finding info for this seemingly simple situation. Can we get FreeNAS to do this? Do we try Greyhole? Is there a distro that can run unionfs/aufs/mhddfs out-of-the-box without messing with manual recompiling? Why is documentation for *nix always so bad?""

Ask Slashdot: Explaining Role-Playing Games To the Uninitiated? 197

Posted by Soulskill from the it's-like-poker-but-with-more-dragons-and-less-violence dept.
An anonymous reader writes "As a kid in the late 1970s and the 1980s, Dungeons and Dragons, as well as many other fine tabletop roleplaying games, figured heavily in my life. From learning about various forms of governments (theocracies, oligarchies, etc.) and Greek, Norse, and Egyptian mythology, to what N.B. and et al. mean, to the social glue that enabled people like me to get together, write cool adventures, problem-solve, and have a blast doing it all, role playing games were a powerful force in my life. The thing is, I still enjoy playing them. A lot. I get together once a month with friends and we play for sometimes up to eight straight hours of epic battles, puzzles, legends, lore, and camaraderie. All of this, unfortunately, seems totally alien to someone who did not grow up with RPGs and who has never experienced the sheer joy of a dungeon crawl. Have you ever had to explain to your spouse or significant other why you value gaming so much, or why it is ok to spend a hunk of time with other gamers? How do you begin to relate it all to them?"

Ask Slashdot: IT Contractors, How's Your Health Insurance? 468

Posted by timothy from the health-care-vs-health-care-finance dept.
An anonymous reader writes "In the tech industry, as the economy continues its downturn, IT folks in my circles who were either laid off or let go are turning to contract work to pay their bills. Layoffs and a decline in tech jobs has affected older IT workers the most. Many of us find it more lucrative and enjoyable in the long run and leave the world of cubicles forever. However, there is much to be said for working for a large company or corporation, and health insurance is one of the benefits we value most. But what happens to those who find themselves in this position at mid-career or later in life? Hopefully they have accumulated enough savings or have enough money in an HSA to survive a major medical emergency. Unfortunately, many do not and some find themselves in dire straits with their lives depending on others for help. I have been working IT contracts mostly now for the past 11 years and I've done very well. I belong to a group insurance plan and the coverage is decent, but as I get older, premiums and copays go up and coverage goes down. If you work contracts exclusively, what do you think is the best plan for insurance? Any preferences?"

"The Australian public, and media, have been largely asleep on this issue and, by Parliament standards, the speed with which this legislation has been rushed through must be a new record — with both major political parties colluding to force it through and quash any thoughts of amendment to its draconian scope. So the time has come — VPN is no longer a luxury but a necessity. The question is, which VPN service providers are best for us poor folks on the arse end of the planet? I have more or less settled on probably going with Private Internet Access. Can any of the BigBrains on Slashdot enlighten me further on the subject of personal VPN — the kind that provides the full spectrum of service as a naked direct link does?"

Ask Slashdot: Options For FOSS Remote Support Software? 247

Albanach writes "I'm sure I'm not alone in being asked to help friends and family with computer issues. These folk typically run Windows (everything from XP onward) or OS X (typically 10.4 onward). Naturally, desktop sharing is often much easier than trying to talk the other end through various steps. I've found free sites like join.me but they don't work with OS X 10.4, neither does the Chrome plugin. I'd also prefer not to compromise security by using a third party in the middle of the connection. Is there a good, free solution I can run on my linux box that supports old and new clients that run Windows, OS X and possibly linux? I'd love it if the users could simply bring their systems up to date, but that doesn't solve the third party issue and it's not easy when it requires a non-trivial RAM upgrade on a Mac Mini."

I am not a fast reader; if I force myself, I could probably finish a standard length novel in a week. English is my second language, so a built-in dictionary would be nice.
