Ask Slashdot: What Distros Have You Used, In What Order? 867

Posted by timothy from the was-it-yggdrasil? dept.
colinneagle writes "Linux dude Bryan Lunduke blogged here about the top three approaches he thinks are the easiest for new users to pick up Linux. Lunduke's, for example, went Ubuntu -> Arch -> openSUSE. It raises a question that Slashdot could answer well in the comments: what's your distro use order from beginning to now? Maybe we could spot some trends."

Ask Slashdot: Explaining Version Control To Non-Technical People? 383

Posted by Unknown Lamer from the it-will-cost-negative-ten-meelion-dollars dept.
New submitter billius writes "I was recently hired (along with another guy) as a web developer at a large university. Our job is to build tools to support the social science researchers on our team. When I got here the codebase was an unholy mess: the formatting was terrible, there were .bak files scattered everywhere and there was no version control system in place. We quickly went to work cleaning things up and implementing new features. My boss was so pleased with our work that she took us out to lunch. During lunch, she asked us if there were any additional tools we needed to do our job more efficiently. We both told her that version control was an invaluable tool for any kind of software development, but had a difficult time describing to her what exactly version control was. I attempted to explain that it created a log of all the changes made to the code and allowed us to make sure that multiple developers working on the same project would not step on each other's toes. I don't think we really got through to her and a few weeks passed with us hearing nothing. Today we were asked by another supervisor if we needed any additional tools and we went through the same spiel about version control. She suggested that we try to write up a brief description of what we wanted and how much it would cost, but I'm drawing a blank an how exactly to describe version control to a person who isn't very technical, let alone a developer. Does anyone out there have any tips on how to sell version control to management?"

I know for a fact that a large amount of the websites I need to have access to on a daily basis for business reasons are censored by the Great Firewall of China. I have been using the Tor Browser for a while now for personal purposes. However Tor has been blocked by China. I was wondering if a personal proxy (connected to a computer back home) would do the trick. Would I be too easily traceable? Basically, I'm wondering if I need to try random public proxies until I find one that works or if there are any other options. What does Slashdot think?"

Ask Slashdot: How To Ask College To Change Intro To Computing? 337

Posted by Unknown Lamer from the use-the-cluebat-luke dept.
First time accepted submitter taz346 writes "I got a Bachelor's degree 30 years ago, but I recently started back to college to get an Associate's degree. Most of the core courses are already covered by my B.A. but one that I didn't take way back when was Introduction to Computing. I am taking that now but have been very disappointed to find that it is really just Introduction to Microsoft Office 2010. That's actually the name of the (very expensive) textbook. It is mindless, boring and pretty useless for someone who's used PCs for about 20 years. But beyond that, why does it have to be all about MS Office and nothing else? Couldn't they just teach people to create documents, etc., and let them use any office software, like Libre Office? It seems to me that would be more useful; students would learn how to actually create things on their computers, not just follow step-by-step commands from a dumbed-down book about one piece of increasingly expensive software. I know doing it the way they do now is easy for the college, but it's not really teaching students much about what they can do with computers. So when the class is over, I plan to write a letter to the college asking them to change the course as I suggested above. I'm not real hopeful, but what the heck. Do folks out there have any good suggestions as to what might be the most persuasive arguments I can make?"

Ask Slashdot: How To Fight Copyright Violations With DMCA? Screenshot-sm 455

Posted by timothy from the which-narrative-do-you-prefer? dept.
szyzyg writes "I've created some popular science videos showing how asteroid discoveries have happened over the last few decades. However I've run into a problem with a religious organization which borrowed my video and redubbed it to promote their religious message. Ultimately I filed a DMCA takedown request via YouTube's site, it's as easy as filling in a form and the video was removed. But this organization has since submitted a counterclaim claiming 'under penalty of perjury' that they do in fact have the rights to this work, and YouTube has reinstated the video. It looks like the only way I can pursue this further is to spend the money to take the organization to court and get an injunction, but even if I did so I'd have to pay court costs up front and since they're based in another country I'd have a difficult time actually collecting any money from the other party. It feels like this other group is simply gambling that I won't spend the time and resources to take further legal action, the DMCA is supposed to provide equal protection but the more lawyer you have the more 'equal' you are. So does anyone have any suggestions for how I should proceed here?"

Ask Slashdot: Hearing Aids That Directly Connect To Smart Phones? 183

mtcups writes "I am a musician/IT guy whose hearing has suffered from VERY LOUD guitar players, (yes I do use earplugs now, but too late), and am faced with the outrageously priced hearing aids $4.5K+/pair and was appalled at their lack of integration with smart phones. It seems obvious to me that I should be able to control the hearing aids via a smart phone interface so I can shape the profile for different environments, and also control features like 'hearing loops' and Bluetooth connections. I have done some research, but my guess is that the hearing aid companies want proprietary systems and don't want a smartphone interface since they would loose control and it would allow for competition for cheaper & better programs. I am not convinced that a combination of good ear-buds, good microphone(s), and a smartphone interface couldn't totally replace these overpriced solutions."

Ask Slashdot: Teaching Typing With Limited Electricity, Computers? 325

Posted by timothy from the muscle-memory dept.
An anonymous reader writes "I am tasked with developing a service project to teach students in a Bangladeshi village how to type. The school has about 500 students, 12 computers donated to them in 2006, and a limited electricity supply. The students will be given job placement opportunities at a local firm in the city once they reach a certain proficiency. Therefore, we are trying to teach as many of them typing skills as possible. The problem: limited electricity, limited computers, many kids. I have some additional funding collected through donations. Instead of buying more computers, I am looking for a cost effective way that does not need a steady flow of electricity. I realize that to teach typing, I do not need a computer. I could achieve the same using a keyboard connected to a display. A solar powered calculator is a perfect example of a cheap device which has a numpad for input and an LCD for display. But so far I have not come across a device that has a qwerty keyboard and an LCD to display what's typed. I know there are some gaming keyboards that have LCDs built in but they are quite expensive. I am aiming to build a device that cost below USD 50. I considered using typewriters but they are in limited supply on the market. I also considered OLPC but it is double my anticipated budget. Do you have other suggestions?" Considering that (at least in China) sub-$50 Android tablets with capacitive screens are already here, I wish the Alphasmart line was cheaper, but apparently it currently starts at $169.

Ask Slashdot: Best Protection Plan For Your Phone? 225

First time accepted submitter nastav writes "Now that I'm eagerly awaiting the delivery of my new shiny iPhone 5, I'm faced with a dilemma — SquareTrade, Applecare Plus, or some other insurance option? I have used SquareTrade in the past for my iPhone 3GS and iPhone 4 (I skipped iPhone 4S). It provided Accidental Damage Handling (ADH) for the iPhone before Apple introduced its own version of ADH. I've had the opportunity to file claims with SquareTrade multiple times, and they handled it quickly and professionally each time. Now that there is a product from Apple itself, I'm not sure which one to get. They are priced similarly (~$100 for a two-year plan, $50 deductible for each ADH incident) Apple limits the number of ADH claims to two, whereas SquareTrade (AFAIK) limits the number of claims to the 'value of the product,' which translates to approx. 600 USD in coverage (or about 4 ADH claims). I've tried reading many comparison articles on the internet without definitive answers. I'm hoping that the tech-savvy folks on Slashdot would help out with a discussion on pros and cons of each, and perhaps add other options into the mix."

Unfortunately that isn't always sufficient to convince potential customers. So I was wondering what other slashdotters do. Are there any free or cheap alternatives to get certificates or other more convincing ways to prove your IT knowledge?"

Ask Slashdot: How Much Is a Fun Job Worth? 397

Nicros writes "I have the good fortune to be a lead software engineer in a really fun company. The culture and people are great, and while the position has some down sides (distance from home, future opportunities), in general I'm quite happy there, and I wasn't looking for a new job. Now, I've had an offer to go be a software director for a new company. The pay is more than 10% better, the location is closer to home, and the people seem nice. I would get to grow a new group as I saw fit, following some regulatory guidelines. Problem is, I just can't decide what to do, and I'm not even sure why I can't decide. Maybe it has to do with leaving a job that I like (something I've never done) that just doesn't sit well with me. Maybe it's fear. I'm 40, so maybe it's just getting older and appreciating stability more. But then again, I have my current position dialed in, and could use a change. I have ambition, and my current company has made every effort to work with me to develop my career — probably more in the business development side, but that could be fun too. That career path is just more vague and longer-term than jumping right into a director position, with no guarantee that it would even work out. In the new company, software is not what this company does primarily; not many people would use the software, so the appreciation level would be much lower than my current position. Has anyone made a transition like this in software? How did it work out? Did you stay or did you go? Why? What's more important, the people and culture at a job, or the opportunities that job presents for future growth?"

Ask Slashdot: Best Practices For Collecting and Storing User Information? 120

Posted by Unknown Lamer from the design-by-committee dept.
New submitter isaaccs writes "I'm a mobile developer at a startup. My experience is in building user-facing applications, but in this case, a component of an app I'm building involves observing and collecting certain pieces of user information and then storing them in a web service. This is for purposes of analysis and ultimately functionality, not persistence. This would include some obvious items like names and e-mail addresses, and some less obvious items involving user behavior. We aim to be completely transparent and honest about what it is we're collecting by way of our privacy disclosure. I'm an experienced developer, and I'm aware of a handful of considerations (e.g., the need to hash personal identifiers stored remotely), but I've seen quite a few startups caught with their pants down on security/privacy of what they've collected — and I'd like to avoid it to the degree reasonably possible given we can't afford to hire an expert on the topic. I'm seeking input from the community on best-practices for data collection and the remote storage of personal (not social security numbers, but names and birthdays) information. How would you like information collected about you to be stored? If you could write your own privacy policy, what would it contain? To be clear, I'm not requesting stack or infrastructural recommendations."

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: 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?"
