New submitter caboosesw writes "A customer of mine recently was hit by a quick and massive DDoS attack. As we were in the middle of things, we learned that there are proxy services of varying maturity to deal with these kinds of outbreaks from the small and mysterious (DOSArrest, ServerOrigin, BlackLotus, DDOSProtection, CloudFlare, etc.) to the large and mature (Prolexic, Verisign, etc.) Have you guys used any of these services? Especially on the lower price point that a small e-commerce (not pr0n or gambling) company could afford? Is a DDoS service really mandatory as Gartner now puts this type of service in the same tier as SEIM, firewalls, IPS, etc?"

New submitter rchoetzlein writes "I am a software developer working independently for five years on various projects, and preparing to go public with my first product. Everyone is telling me I should make it open source. I would love to, but I just don't see how an early startup can afford to become profitable on service alone. My projects are no longer small-scale hobbies, they are large frameworks, and I need to make a living. Any ideas on business models that would allow me to open source while guaranteeing I can feed myself?"

An anonymous reader writes "I was looking at multimedia players from brands such as SumVision, Noontec and Western Digital. They all seem to be some device which accepts a USB hard-drive and commands from an IR remote control, and throws the result over HDMI. I have my own idea of what a hardware multimedia player should do (e.g. a personalized library screen for episodes, movies and documentaries; resume play; loudness control; etc.). I also think it will a good programming adventure because I will have to make the player compatible with more than a few popular codecs. Is this an FPGA arena? Or a mini-linux tv-box? Any advice, books or starting point to suggest?" There certainly have been a lot of products and projects in this domain over the years, but what's the best place to start in the year 2012?

New submitter everithe writes "Dear Slashdot, I am nearing the end of my undergraduate years and hoping to continue on in academia, probably focusing on condensed matter physics. Recently I've noticed some alarming pessimism among Slashdotters about the state of science — that fraud is rampant and that people honestly trying to do science are less likely to be recognized and obtain tenure. Obviously I am very interested in doing real and useful science, but am worried that this could conflict with my ability to put food on the table. My question is, how bad is it really, and do you have any advice for how one just starting out might survive in such an environment?"

First time accepted submitter rodrix79 writes "Hi all. I am trying to move from Windows to Linux (Ubuntu, but maybe to Mint). The problem is I telecommute full time and I am having a hard time trying to find the right tools to keep communication flowing with my clients (which are mostly on Windows / Mac). Any good recommendations from Linux telecommuters?"

dargaud writes "I live in an alpine setting and I'd like to be able to remotely view various remote valleys to check for ice formations for winter climbing. I wonder if there are cheap drones that could do that. Requirements would be: GPS guided on a preset route (no remote control necessary, and anyway there's no line of sight), at least 20km autonomy, 1 or 2 cameras on the sides to record valley walls, easy launching and autonomous landing (parachute?) at predefined point, ground detection to avoid crashes (if preset route is wrong or GPS echoes on valley walls as is often the case). Is there anything commercially available cheap enough, or any DIY that doesn't require a year of assembly?"

First time accepted submitter g7a writes "I've been given the task of testing new hardware for the use in our servers. For memory, I can run it through things such as memtest for a few days to ascertain if there are any issues with the new memory. However, I've hit a bit of a brick wall when it comes to testing hard disks; there seems to be no definitive method for doing so. Aside from the obvious S.M.A.R.T tests ( i.e. long offline ) are there any systems out there for testing hard disks to a similar level to that of memtest? Or any tried and tested methods for testing storage media?"

MrSeb writes "Today is World Backup Day! The premise is that you back up your computers on March 31, so that you're not an April Fool if your hard drive crashes tomorrow. How do Slashdot users back up? RAID? Multiple RAIDs? If you're in LA, on a fault line, do you keep a redundant copy of your data in another geographic region?"

scubamage writes "Six weeks ago, my home was broken into while my fiance and I were at work. Two laptops were stolen, an iPad, a power brick, a safe (complete with several years worth of taxes, my birth certificate, and old copies of my driver's license), a digital SLR, and several other costly items. We are now dealing with an attorney because the homeowner's insurance is fighting us on a number of items and we're not backing down. It has been a nightmare. However, we've now noticed that someone has been visiting our house during the day. There has been garbage left sitting on our back porch table, so its unlikely to have blown there. We've also seen footprints in our garden that are not there in the morning. Our neighborhood is essentially empty during the day, and we want to know who is on our property while we're not. If we're really lucky, reporting it to the police could recover some of our property. My fiance has asked me to assemble a home security system that is motion activated, and both notifies us of an entry, as well as records video or rapid HD stillframes when sensing motion. The goal is to do this cheaply and more effectively than going with a private security company like ADT (who, consequently, our police department told us to ignore due to the incredibly high rate of false alarms). We've already gotten the dog and the gun, so we have those bases covered. What suggestions do you have on setting up home security systems, and what have you done to build one in the past?"

DudeTheMath writes "Here in the Sunshine State (Florida), solar should be a no-brainer. However, large oaks that require permits to trim partially shade my roof. I'd like to (inexpensively) 'pre-qualify' my roof for effective panel area. Googling for 'home solar testing' gets me equipment for checking the efficiency of an existing PV installation. Do any makers know what I can do on my own in terms of placing a few individual cells and, over a year, measuring and recording their output, so I can get an idea whether solar would be cost-effective for me?"

gambit3 writes "My wife and I are expecting our first child in 3 months, and one of the decisions we still have to make is whether to store our baby's cord blood. Even if we decide the upfront cost is worth it, there is still the question of using a public bank or a private one (and which one to trust), and whether to also store umbilical cord tissue for stem cells. Does you have any experience or suggestions?"

gbrumfiel writes "Africa has some of the poorest soil of anywhere on the earth, and over farming is only making matters worse. As the population grows, governments and NGOs must decide whether to subsidize chemical fertilizers like those used in the west or promote more sustainable agricultural practices. In Malawi, the government has decided to subsidize fertilizers, with impressive results. Corn yields have tripled since the subsidies were introduced. More sustainable practices, such as fertilizer trees can't deliver those kind of results in just a few years. The question is simple: does Africa follow the same, unsustainable road as the rest of the world? Or do they become a testing ground for potentially game-changing new techniques? OR is there a third path? Discuss."

mtaht writes "Has anyone, besides those that worked on byte queue limits, and sfqred, had a chance to benchmark networking using these tools on the Linux 3.3 kernel in the real world? A dent, at least theoretically, seems to be have made in bufferbloat, and now that the new kernel and new iproute2 are out, should be easy to apply in general (e.g. server/desktop) situations." Dear readers: Have any of you had problems with bufferbloat that were alleviated by the new kernel version?

You've probably noticed that Slashdot's been running some video lately. There are a lot of interesting people and projects in the world we'd like to present in video form, but some of them are too far away for the corporate overlords to sponsor travel to shoot footage in person. (Another reason my dream of parachuting to McMurdo Station will probably never manifest.) We've been playing around with several things on both the software and hardware side, but in truth, all of them have some flaws — whether it's flaky sound (my experience with the otherwise pleasing RecordMyDesktop on Linux), sometimes garbled picture (Skype, even on seemingly fast network connections), or video quality in general. (Google Hangouts hasn't looked as good as Skype, for instance. And of the webcams built into any of the laptops we've tried, only Apple's were much worth looking at. Logitech's HD webcams seem to be a decent bargain for their quality.) We've got a motley bunch of Linux, OS X, and Windows systems, and can only control what's on our side of the connection: interviewees may have anything from a low-end laptop with a built-in webcam to elaborate conferencing tools — which means the more universal the tools, the better. (There may not be any free, open source, high-quality, cross-platform video conferencing tools with built-in capture and a great UI, but the closer we can get, the better.) With all that in mind, what tools and workflow would you suggest for capturing internet conversations (with video and sound), and why? Approaches that minimize annoyance to the person on the other end of the connection (like the annoyance of signing up for an obscure conferencing system) are especially valuable. We'd like to hear both sides, so please chime in if you've had especially good or bad experiences with capturing remote video like this.

rbowen writes "Nine years ago, Slashdot readers discussed what makes an Open Source project successful. The answers were varied, of course. An academic paper summarized the results, agreeing (albeit with more precision) that motivations for Open Source projects are varied. Has anything changed since then? In the era of mobile apps, social media, and Google Ad revenue, have the definitions of Open Source project success changed at all? Have your reasons changed for being involved in Open Source?"
