Volanin writes "Currently I use a triple boot system on my Macbook, including MacOS Lion, Windows 7, and Ubuntu Precise (on which I spend the great majority of my time). To share files between these systems, I have created a huge HFS+ home partition (the MacOS native format, which can also be read in Linux, and in Windows with Paragon HFS). But last week, while working on Ubuntu, my battery ran out and the computer suddenly powered off. When I powered it on again, the filesystem integrity was OK (after a scandisk by MacOS), but a lot of my files' contents were silently corrupted (and my last backup was from August...). Mostly, these files are JPGs, MP3s, and MPG/MOV videos, with a few PDFs scattered around. I want to get rid of the corrupted files, since they waste space uselessly, but the only way I have to check for corruption is opening them up one by one. Is there a good set of tools to verify the integrity by filetype, so I can detect (and delete) my bad files?"
An anonymous reader writes "I was a consultant for nearly 20 years and I got into projects where I had to work with a huge variety of software, operating systems, hardware, programming languages, and other assorted technologies. After retiring from that I have spent the last 10 years in a completely different sector. Now I find myself wanting to really focus on coding for personal reasons. You can imagine how out-of-touch I am since I never really was more than a hack to begin with. I can learn syntax and basics in a weekend, question is, what Language should I become native to? Never liked anything 'lower-level' than C, and I don't have the funds to 'buy' my development environment....help me Slashdot, you're my only hope."
New submitter brabq writes "Now that I have a couple of CableCard tuner devices in the house (including the network-based HDHomeRun Prime), I'm thinking of buying one of those all-in-one touchscreen PCs for our kitchen (yeah, something I've always sworn against for future repair reasons). The idea is that it would be used primarily for (1) watching TV, via the aforementioned Prime and WMC, and (2) light web surfing (recipes, some sort of video chat possibly). Does anyone have any experience with these types of devices in a kitchen-like setting (where I'd like to use a touchscreen over having a keyboard/mouse on a kitchen counter)? I keep hearing that Windows 8 is going to have some added benefits to this type of setup — is it worth waiting for its release? My end goal is it has to have a high WAF ... if my wife doesn't like its appearance on the counter or finds it useless, then the whole thing will be a waste."
An anonymous reader writes "I have at least 10 assorted hard drives ranging from 100 GB to 3 TB, including external drives, IDE desktop drives, laptop drives, etc. What's the best way to setup a home NAS to utilize all this 'excess' space? And could it be set up with redundancy built-in so a single drive failure would cause no data loss? I don't need anything fancy. Visibility to networked Windows PCs is great; ability to streak to Roku / iPad / Toshiba etc would be great but not necessary. What's the best way to accomplish this goal?"
mcmadman writes "The multi-zone audio player I'm working with uses an almost decade old card/software combo that is prone to crashes and other anomalies. I would like to know if there are open source (read 'free') or other alternatives that would allow multiple simultaneous playlists played through the myriad of audio interfaces out there. The line outs are then plugged into a CobraNet matrix, which handles the distribution of the music/sound to their respective areas. I'm looking at eight channels minimum, timed playlist start/stops, and triggered announcements. So far the only software and hardware I've found are proprietary broadcasting solutions which tend to be a bit heavy on the wallet or meant for home use."
jawtheshark writes "I'm building a house, and obviously I want a modest network built-in. Nothing fancy, two RJ-45 per room, four in the living room, and that's basically it. I already got myself a rack mountable Cisco Small Business switch and I have a self-built 4U server (low-power, won't make much heat) which can be rack mounted (505mm deep). Now, the construction company suggests a wall mounted rack (6U: 340mm x 600mm x 480mm — 6U definitely won't be enough, but a 12U model exists). It's not expensive, but I have never worked on a rack where the backside is unreachable. (For work, I get to work in a data center with huge racks that are accessible from both sides). Now obviously, I don't need a data center-grade rack, but these wall-mounted racks scream 'switch-only' racks to me. What are your experiences? Is it possible to put servers in racks like these, or should I find a 'both-side-accessible' rack instead?"
gbrumfiel writes "The battle over whether to publish research into mutant bird flu got editors over at Nature News thinking about other potentially dangerous lines of scientific inquiry. They came up with a non-definitive list of four technologies with the potential to do great good or great harm: Laser isotope enrichment: great for making medical isotopes or nuclear weapons. Brain scanning: can help locked-in patients to communicate or a police state to read minds. Geoengineering: could lessen the effects of climate change or undermine the political will to fight it. Genetic screening of embryos: could spot genetic disorders in the womb or lead to a brave new world of baby selection. What would Slashdotters add to the list?"
First time accepted submitter cos(0) writes "Between O'Reilly, Wrox, Addison-Wesley, The Pragmatic Bookshelf, and many others, software developers have a wide variety of literature about languages, patterns, practices, and tools. Many publishers even offer subscriptions to online reading of the whole collection, exposing you to things you didn't even know you don't know — and many of us learn more from these publishers than from a Comp Sci curriculum. But what about publishers and books specializing in tech underneath software — like VHDL, Verilog, design tools, and wire protocols? In particular, best practices, modeling techniques, and other skills that separate a novice from an expert?"
wytcld writes "Sending an individually-written e-mail to my state senator resulted in an automated response saying that since she receives hundreds of e-mails a day, there might be no personal response, but please don't take that to mean she hasn't read my e-mail. So I contacted her again suggesting that was a pretty poor answer. Most of the e-mails she receives are mass mailings coordinated by various interest group websites. Why doesn't she put those to the side, I asked, and prioritize response to individual e-mails from constituents who've taken the time to actually write? Her response? She often can't tell the difference at first, so spends time drafting responses to the first instances of group e-mail spam, and gets diverted from responding to those who really write her. Are there tools out there which a politician can use to identify the incoming group-think blasts and put them to to side? It's easy enough to imagine sorting by repeated content or headers, if I ran the mail server, but I'm looking for packages already out there that a state-level representative, with no staff to speak of, might use to cut through the mess and prioritize communication with constituents who care enough about an issue to draft their own thoughts."
New submitter grzzld writes "I am a systems analyst for a County in New York. Last year I made a SharePoint site that manages grants and it was well received. So much so that it won a NACo award. Since then, there have been several requests from other municipalities from around the country who would like to get this SharePoint site. The county is trying to figure out how to protect ourselves from people making money from it and having people hold us liable if it they use it and something goes awry. I am afraid that ultimately nothing will be done and the site will not be shared since at the end of the day it is much easier to not do anything and just say no. I proposed that we license it under an Open Source agreement but I am not versed enough in the differences between all of them. It is also unclear to me if I could do this since the nature of the 'program' is a SharePoint site. It seemed like CodePlex would be a good place to put this since it is Microsoft centric and it an open source initiative. I just want to contribute my work to others who may find it useful. The county just wants to make sure they can't be held liable and have somebody turn my work around and make a buck. How can I release this to the world and make sure the county's concerns are addressed?"
raolin writes "I have been running without television service for the last few years, relying instead on Netflix Streaming, Hulu Plus, Amazon, and my personal video library. I have the latter indexed and easily searchable, but I have not managed to find a good aggregator for the streaming services that I use, so when I have friends over and the question 'Can we see X?' is asked, I have to search three streaming sources, which is kind of a drag. I know Netflix has a search API that I could work with, and it seems at least possible that Hulu and Amazon do as well, but before I try to build something myself I thought I'd ask the community. Any thoughts?"
New submitter waferthinmint asks "What is the best book for my son to use to teach himself to program? He wants to study on his own but everything seems to assume an instructor or a working theoretical knowledge. He's a bright kid but the right guide can make all the difference. Also, what language should he start with? When I was in HS, it was Basic or Pascal. Now, I guess, C? He has access to an Ubuntu box and an older MacBook Pro. Help me Slashdot; you're our only hope."
snydeq writes "J. Peter Bruzzese questions whether Microsoft receives unfair criticism in the media, while Apple, Facebook, and Google seem to get away from missteps unscathed. 'I've noticed an unfair, ongoing trend: If Microsoft does something a little off, it gets bashed into the ground for it. But if Google, Facebook, or Apple (all three of which can be categorized, like Microsoft, as The Man in their own rights) missteps, it generally gets mild reprimands and even support from the media and those drinking the Kool-Aid.' Do you feel any inherent media bias in its coverage of the tech industry?"
skywiseguy writes "I have only used Kickstarter to back a single project so far, but one of the backers of that project pointed us to a project promising video capable glasses which was once one of the top 10 highest funded projects in Kickstarter history. After reading through the comments, it is obvious that the project has not met its expected deadline of 'Winter 2011,' but the project team rarely gives any updates with concrete information. All emails sent to them by backers get a form letter in reply, they routinely delete negative comments from their Facebook page, and apparently very soon after the project was funded, they posted pictures of themselves on a tropical beach with the tagline, 'We are not on a beach in Thailand.' Their early promotions were featured on Engadget and other tech sites but since the project was funded they've rarely, if ever, communicated in more than a form letter. So at what point can a project like this be considered to have failed? And if you had backed a project with this kind of lack of communication from the project team, what would you consider to be the best course of action? Disclaimer: I have not backed this project, but I am very interested in funding Kickstarter projects and I do not want to get caught sending money to a less than reputable project. According to the above project's backers, Kickstarter claims to have no mechanism for refunding money to backers of failed projects and no way to hold the project team accountable to their backers. This does not seem like a healthy environment for someone who is averse to giving their money to scam artists."
An anonymous reader writes "'The Harrier' (or 'Eastern star,' as it is also called), is very well known, and is considered to be one of the best paper airplane designs. After much searching and trying, I have not found a better plane. So, I am asking Slashdot: is there anything that beats 'The Harrier' in a competition (indoors or outdoors)? This would be a really nice geek skill!"
