How Do You Extend Your Wireless Connection? 214

ganjadude writes "So I am moving to a location where the cell signal is very poor (I don't get signal inside my house), and I have been looking at wireless extenders such as the ones that Sprint and Verizon have. I am brought down by the cost (Sprint charges monthly, Verizon $250 up front, AT&T.... well they are AT&T). Being that this is Slashdot, and a lot of us live in basements (I kid!), I assume that some of the crowd has had this issue in the past. What have you done, or what alternatives are available to someone in such a situation?"

Open Source Alternative To Google Earth? 190

aws910 writes "Today, I fired up Google Earth to find that the 'points of interest' category had been removed, and a single checkbox is in its place. Certain layers are now entirely inaccessible. Google triggered a user revolt, but admitted fault, and promised to restore full functionality someday. In the meantime, I've found a lack of plausible alternatives. Bing seems nice, but Moonlight crashes the browser on any machine I use, and I'd rather use OSS anyway ... which made me realize there doesn't seem to be a good open-source alternative to Google Earth. Am I missing something?"

Recommendations For C++/OpenGL Linux Tutorials? 117

QuaveringGrape writes "After a few years of Python I've recently been trying to expand my programming knowledge into the realm of compiled languages. I started with C, then switched over to C++. A friend and longtime OpenGL programmer told me about NeHe's tutorials as a good step after the command-line programs started to get old, but there's a problem: all the tutorials are very Windows-based, and I've been using Linux as my single platform for a while now. I'm looking for suggestions for tutorials that are easy to learn, without being dumbed down or geared towards non-programmers."

Is the Line-in Jack On the Verge of Extinction? 411

SlashD0tter writes "Many older sound cards were shipped with line-out, microphone-in, and a line-in jacks. For years I've used such a line-in jack on an old Windows 2000 dinosaur desktop that I bought in 2000 (600 Mhz PIII) to capture the stereo audio signal from an old Technics receiver. I've used this arrangement to recover the audio from a slew of old vinyl LPs and even a few cassettes using some simple audio manipulating software from a small shop in Australia. I've noticed only recently, unfortunately, that all of the four laptops I've bought since then have omitted a line-in jack, forcing me to continue keeping this old desktop on life support. I've looked around for USB sound cards that include a line-in jack, but I haven't been too impressed by the selection. Is the line-in jack doomed to extinction, possibly due to lobbying from vested interests, or are there better thinking-outside-the-box alternatives available?"

How To Avoid a Botnet Infection? 396

Taco Cowboy writes "Two of the networks in the company I work for have been zombified by different botnets. They are taken off the grid as we speak. We thought we had taken precautions against infection, such as firewall and anti-viral programs, but for some reasons we have failed. Is there any list of precautionary steps available?" I'd suggest port blocking 80 for any computer that is detected running a web browser, but that might prevent some percentage of legitimate work.

What Is Holding Back the Paperless Office? 511

Drethon writes "CNN has an article (are we up to the millionth article on this topic?) asking if the paperless office has arrived. This got me wondering, what are the main things holding back the paperless office? Just off the top of my head, the main thing keeping me printing out documents is the ability to spread a dozen pages of a document under review out on my table and marking it up by hand. PDF and Word markups are not too bad but they still lack the ability to spread many pages out to look over at the same time and could be improved to make markup a bit less restrictive. I do find myself printing out less with the use of dual monitors to have source documents and work under progress up at the same time, perhaps something like Microsoft's tabletop computer used as a desk will let me have at least a paperless desk. I know there are other reasons why offices are not becoming paperless. What are your reasons?"

Need Help Salvaging Data From an Old Xenix System 325

Milo_Mindbender writes "I've recently gotten ahold of an old Altos 586 Xenix system (a late '80s Microsoft flavor of Unix) that has one of the first multi-user BBS systems in the US on it, and I want to salvage the historical BBS posts off it. I'm wondering if anyone remembers what format Xenix used on the 10MB (yes MB) IDE hard drive and if it can still be read on a modern Linux system. This system is quite old, has no removable media or ethernet and just barely works. The only other way to get data off is a slow serial port. I've got a controller that should work with the disk, but don't want to tear this old machine apart without some hope that it will work. Anyone know?"

Memorizing Language / Spelling Techniques? 237

NotesSensei writes "My kids are learning Chinese in school. While the grammar is drop-dead simple, writing is a challenge since there is no relation between sound and shape of the characters. I would like to know any good techniques (using technology or not) to help memorize large amounts of information, especially Chinese characters. Most of the stuff I Googled only helps on learning speaking."

Business-Suitable Document Authentication System? 130

ram.loss writes "The company I work for has decided to go paperless for all memos and internal correspondence. In addition to the central administration, the company has three more or less autonomous, physically separated divisions; that means we do not have a common IT infrastructure across all of them. Since I am the only resemblance we have to an IT department at my division, I have been commissioned with evaluating the available technology to manage and authenticate all correspondence, although it is not my area of expertise (I have a CompSci degree, but for many years have specialized in transportation modeling software). My initial thought was to use a document management system like Plone (this is the system I'm familiar with); from what I have read, that would take care of the management part, but what about authentication? We need each document to be signed, and a fully auditable system that keeps track of who signed what document, who received it and when. It also must take into account the handling of external correspondence in the future, where a recipient outside the company must have the means to return an authenticated document as a response. I'm aware that I'm leaving out a lot of details, like how the documents will be signed, the legal implications, etc., but for the time being I'm only interested in the experiences of the Slashdot crowd with such systems, and hopefully finding out enough information to hand over the matter to (or hiring) somebody more qualified, once I know what to look for. Has anybody out there used a similar system? Am I in way over my head?"

Health Care Reform 2044

It appears that today might be the end of a very long road to health care reform. There's been a lot of debate on the subject really leading back before the election. The mainstream sounds like an echo chamber, so I'm hoping you guys have better insight. Will this bill do what the administration claims to do, or is it as bad for the future of America as Fox says?

What Free Antivirus Do You Install On Windows? 896

Techman83 writes "After years of changing between AVG Free + Avast, it's coming time to find a new free alternative for friends/relatives who run Windows. AVG and Avast have been quite good, but are starting to bloat out in size, and also becoming very misleading. Avast recently auto updated from 4.8 to 5 and now requires you to register (even for the free version) and both are making it harder to actually find the free version. Is this the end of reasonable free antivirus, or is there another product I can entrust to keep the 'my computer's doing weird things' calls to a minimum?"

Good Language Choice For School Programming Test? 407

An anonymous reader writes "The Australian Informatics Olympiad programming test is being run in a couple of months. I'm an experienced programmer and I'm thinking of volunteering to tutor interested kids at my children's school to get them ready. There will be children of all levels in the group, from those that can't write 'hello world' in any language, to somewhat experienced programmers. For those starting from scratch, I'm wondering what language to teach them to code in. Accepted languages are C, C++, Pascal, Java, PHP, Python and Visual Basic. I'm leaning towards Python, because it is a powerful language with a simple syntax. However, the test has a run-time CPU seconds limit, so using an interpreted language like Python could put the students at a disadvantage compared to using C. Is it better to teach them something in 2 months that they're likely to be able to code in but possibly run foul of the CPU time limit, or struggle to teach them to code in a more complicated syntax like C/C++ which would however give them the best chance of having a fast solution?"

What Aspects of Open Source Projects Do You Avoid? 344

paulproteus writes "I'm a Debian developer and a part-time contributor to a few smaller projects. I do a lot of free software-y and open source-y things. Sometimes, though, I don't do them. I figure some other Slashdotters might have similar hang-ups — we contribute to a project, but there are parts that we really dread thinking about. So I wrote a post about having these hang-ups, and I made a place on the web to share how others can help your project. What are the parts that, in your projects, you would be relieved if someone else looked at for you?"

Why Are Digital Hearing Aids So Expensive? 727

sglines writes "Over the last couple of years I've been slowly getting deaf. Too much loud rock and roll I suppose. After flubbing a couple of job interviews because I couldn't understand my inquisitors, I had a hearing test which confirmed what I already knew: I'm deaf. So I tried on a set of behind-the-ear hearing aids. Wow, my keyboard makes clacks as I type and my wife doesn't mumble to herself. Then I asked how much: $3,700 for the pair. Hey, I'm unemployed. The cheapest digital hearing aids they had were $1,200 each. If you look at the specs they are not very impressive. A digital hearing aid has a low-power A-to-D converter. Output consists of D-to-A conversion with volume passing through an equalizer that inversely matches your hearing loss. Most hearing loss, mine included, is frequency dependent, so an equalizer does wonders. The 'cheap' hearing aids had only four channels while the high-end one had twelve. My 1970 amplifier had more than that. I suppose they have some kind of noise reduction circuitry, too, but that's pretty much it. So my question is this: when I can get a very good netbook computer for under $400 why do I need to pay $1,200 per ear for a hearing aid? Alternatives would be welcome."

Licensing an Abandonware Game? 148

WolverineOfLove writes "I'm recreating a 1980s abandonware game with copyrights that have been seemingly unused for the past 18 years. The situation is detailed further in a Slashdot journal entry I just wrote, but in short: Is it worth dealing with all the copyrights and paying money if I want to recreate an abandonware title as an open source game? I know there are legal implications to certain decisions I might make, but there is a real possibility that this game's copyright holder will do nothing with the rights, and I'd much prefer preserving it for others than letting it fade away."

Best Pre-Paid Data Plan For a Visit To Germany? 153

code prole writes "With two upcoming trips to Germany, and no readily available Internet (Wi-Fi or otherwise) in the location where we'll be staying, I'm looking for a no-contract USB stick and pre-paid data plan. Vodafone has a huge selection of USB sticks but has proven to be unresponsive to questions about data plans. And the US-based T-Mobile Help Center was clueless about getting the device in Europe and using it there. Hopefully the Slashdot community has some suggestions. Any duds to avoid?"

Best Smartphone Plan Covering US and Canada? 199

j00bhaka writes "I am a US citizen attending university in Nova Scotia, Canada. I currently have the Verizon America and Canada plan (also known as the North American plan). My bill is currently around $80-$100 per month. I chose this for a couple reasons. One, I have had my number for about 7 years. Two, I do not permanently live in Canada. I live in Canada for 8 months out of the year at school, then travel home for the summer months. Either way, I would be dealing with international roaming without having both countries in my plan. Currently, I obviously don't have a smartphone. Through Verizon, I could purchase one, and add their international unlimited data plan on top of my (already) hefty phone bill. I have looked into Telus and Rogers here in Canada and cannot find anything better. As a student, my budget is obviously limited. Is there any way to reasonably have (and utilize) a smartphone while I am living in both countries? If so, what do you suggest I do?"

Digitizing and Geocoding Old Maps? 235

alobar72 writes "I have quite a few old maps (several hundreds; 100+ years old, some are already damaged – so time is not on my side). What I want to do is to digitize them and to apply geo-coordinates to them so I can use them as overlays for openstreetmap data or such. Obviously I cannot put those maps onto my €80 scanner and go. Some of them are really large (1.5m x 1.5m roughly, I believe) and they need to be treated with great care because the paper is partly damaged. So firstly I need a method or service provider that can do the digitizing without damaging them. Secondly I need a hint what the best method is to apply geo coordinates to those maps then. The maps are old and landscape and places have changed, it maybe difficult to identify exact spots. So: are there any experiences or tips I could use?"

Best Resource For Identifying Legit Applications? 255

bjb writes "While helping a somewhat computer illiterate person figure out a problem recently, they mentioned that PDF files had recently stopped working. Upon investigation I found something installed called 'PDF Suite.' Never having heard of it, I Googled it with 'malware' and other key words, but nothing turned up, though my suspicion remained (and was somewhat confirmed by WOT.) So my question is, where can you go to find out if something is legitimate? Because the person I'm helping is on a dial-up connection, downloading malware detection applications (and updates) is too heavy consider. And I don't maintain a USB stick with such apps, since I don't do this kind of thing very often. Where can you quickly find information?"

Making Sense of CPU and GPU Model Numbers? 555

b4dc0d3r writes "How do you make sense of the various model numbers or naming schemes for CPUs, graphics cards, and the related chipsets? All I want is something that will run Oblivion and output full 1080 video to a TV. Last time I built my own computer I just went to Pricewatch, made a few easy choices, and everything came to my door. Do I really have to research the differences among Core i5, Core 2 Duo, Pentium 4, Pentium D, Sempron, Athlon, Phenom ...? And that's just the processor. Is there a reference somewhere? In short, how do you buy a computer these days?"
