An anonymous reader writes "My kid is now 1 year old and I already have 100G of digital video (stored on DVDs, DVD quality) and photos. How should I store it so that it's still readable 10 to 20 years from now? Will DVDs stil be around, and readable, 10 years from now? Should I plan for technology changes every 5 to 10 years (DVD->Blue-ray->whatever)? Is optical storage better, or should I try to use hard drives (making technology changes automatic)? And, if the answer is optical, how do you store optical disks so that they last?"

An anonymous reader writes "I'm an adult looking to learn how electronics work and have some fun building projects. But all the kits I've found online are for kids 8-10 years old, and they don't really explain the principles — they just color-code where to place components on boards. Are there any kits aimed at adults? I know if anyone has got the answer, it's this community."

MyLongNickName writes "Less than a month ago I took a position at a smaller firm (around 50 employees) as an IT Manager. As you might expect from the size of the company, I oversee quite a variety of tasks. I come from a background of computer programming, and am definitely not a master of every function. We rely on third-party solutions providers for areas like our networking, web hosting, phone systems, etc. I am used to working in a larger environment with a large IT staff (and not just because of super sizing at McDonald's). Just the daily rubbing elbows allowed me to stay current in areas that I did not directly touch. And when I had a question, I personally knew someone who could answer my question. I am not in that environment now. How do I stay current? I don't want to be a master of every technology, but I want to be aware of trends in the industry. I want to not depend on one contractor advising me."

An anonymous reader writes "Now that the Swedish government (in its infinite wisdom) has passed a law allowing them to monitor email traffic, a question that I think a lot of people are asking (or at least should be asking) is: 'What can I do to improve my privacy?' The answer is not obvious. So, what are the best solutions for seamless email encryption, search privacy, etc? What are your experiences with PGP vs GPG vs ...? In this day and age, why is the use of this type of privacy technologies still so limited? Why isn't there a larger movement promoting the use of privacy tools? Also, what is in your opinion the largest privacy concern? Search tracking? Email transfer? I believe this is an interesting question not only for Swedes, but for everyone. Lots of traffic is passing through Sweden, but more importantly, the Swedish government is not alone in using this type of surveillance."

zorro6 writes "I thought this might be an interesting question/topic and it would sure help me to get some kind of answer. I recently got internet service from a small, local wireless ISP in my area (south central Colorado, USA). The strange thing is that many, many web sites think I am in Quebec, Canada when I use the service. Evidently some geolocation service thinks my IP address indicates I am in Canada. I have checked the obvious. The WHOIS information for my IP correctly indicates a location of Durango, CO. So the bad info is coming from some more sophisticated geolocation service. My ISP is at a loss as to how to fix this but it is causing me a lot of grief. Many of the ads I get shown on Yahoo! for instance are in French! Certain sites won't sell me goods or services because they don't do business in Canada. So far I know that Yahoo! (or their ad provider), Nvidia, Movielink, etc. all think I am in Canada. I would sure appreciate any help/info on how to get this corrected."

cconnell writes "I am working on a PhD in software engineering at Tufts University. My interest are the general principles of good software design, and I am looking for links/references on this topic. The question is: What design/architecture qualities are shared by all good software? Good software means lacking in bugs, maintainable, modifiable, scalable, etc... Please don't tell me 'use object oriented methods' or 'try extreme programming.' These answers are too narrow, since there is good software written in COBOL, and by 1000-person teams for DoD projects. I am looking for general design principles. If it helps, I am trying to build on the ideas in this article from some years back."

An anonymous reader writes "The small travel agent that I work for recently received an email from one of our competitors with several thousand of their potential customers in the 'To:' and 'Cc:' fields. My boss now wants to use these addresses to send unsolicited advertisements. I would like to convince him not to do this, as I believe that this practice is morally wrong and legally dubious. However, morals don't go very far in the business world, so I'm asking Slashdot: what business-oriented arguments can I use to dissuade my boss from spamming?"

bLanark writes "Some time ago, most electronics were soldered with old-fashioned lead solder, which has been tried and tested for decades. In 2006, the EU banned lead in solder, and so most manufacturers switched to a lead-free solder. Most made the switch in advance, I guess due to shelf-life of products and ironing out problems working with the new material. Lead is added to solder as it melts at low temperature, but also, it prevents the solder from growing 'whiskers' — crystalline limbs of metal. The effect of whiskers on soldered equipment would include random short-circuits and strange RF-effects. Whiskers can grow fairly quickly and become quite long. Robert Cringley wrote this up this some time ago, but it seems that the world has not been taking notice. I guess cars (probably around 30 processors in a modern car) and almost every appliance would be liable to fail sooner than expected due to tin whiskers. Note that accelerated life-expectancy tests can't simulate the passing of time for whiskers to grow. I've googled, and there is plenty of research into the effects of tin whiskers. I should point out that the Wikipedia page linked to above states that tin whisker problems 'are negligible in modern alloys,' but can we trust Wikipedia? So: was the tin whisker problem overhyped, was it an initial problem that has been solved in the few years since lead-free solder came into use, or is it affecting anyone already?"

shanen writes "A story from the NYTimes about metering internet traffic caught my eye. I thought the exchange of information over the Internet was supposed to be a good thing? Couldn't we use technology more constructively? For example, if there is too much network traffic for video and radio channels, why don't we offset with the increased use of P2P technologies like BitTorrent? Why don't we use wireless networks to reduce the traffic on the wired infrastructure? Such technologies often have highly desirable properties. For example, BitTorrent is excellent for rapidly increasing the availability of popular files while automatically balancing the network traffic, since the faster and closer connections will automatically wind up being favored. Instead, we have an increasing trend for anti-technology technologies and twisted narrow economic solutions such as those discussed in the NYTimes article, and attempts to restrict the disruptive communications technologies. You may remember how FM radio was delayed for years; part of the security requirements of a major company includes anti-P2P software, as well as locking down the wireless communications extremely tightly — but there are still gaps for the bad guys, while the main victims are the legitimate users of these technologies. Can you think of other examples? Do you have constructive solutions?"

c0d3h4x0r writes "It's no accident that 'whatcouldpossiblygowrong' is one of the most common tags applied by this community to stories about proposed ideas or laws. The ability to spot and predict faults is a big part of what makes a great engineer. It starts with having a healthy skepticism about the world, which leads to actual critical thinking. Many books and courses teach critical thinking skills, but what is the best way to encourage and teach someone to maintain a healthy dose of skepticism? Is it even a teachable skill, or is it just an innate part of the geek personality?"

wifeoflurker writes "Can someone give me recommendations for a desk chair to give my husband as a Father's Day gift? He currently uses a cheap one he got from Office Max, but I want him to have a really comfortable one. He spends his life in this chair (coding and lurking on Slashdot). I don't have time to research good chairs on the internet today (I'm chasing my 10 month old around, and she seems to get into the most mischief when I'm staring at the computer screen), so I figured a few folks here might share their personal recommendations." Has there been any great progress in the state of the art (of sitting) since the last time readers sought recommendations for back-friendly chairs a few years back, or the perfect computer chair nearly a decade back? Is there even such a thing as a back-friendly chair, or should we all be in astronaut-style lounge workstations?

Writing "Surely there is a better way," eggy78 asks "With the ability to get information anywhere in the world in seconds, and the virtually immediate obsolescence of any printed work, why are journals such an important part of academic research? Many of these journals take two or more years to print an article after it has been submitted, and the information is very difficult (or expensive) to obtain. Does this hinder technological advancement? There are certainly other venues for peer review, so why journals? What do they offer our society? Are they just a way to evaluate the productivity of professors?"

ShamelessHero writes "I was recently hired as a Field Engineer, deploying servers, workstations and peripherals to sites around the globe. I try and travel light, but try as I might, the Emergency Repair Kit has ruined three sets of luggage so far. I know there are Slashdotters here who travel internationally and through some treacherous environs. What are the best travel tips you've come up with? Recommendations for durable, light yet large luggage are much appreciated."

Precinct Election Judge writes "I am one of the Republican Party Precinct Chairs in Harris County, Texas. Since in 2006 Republican Rick Perry won the Governor's race in my precinct I will be the head election judge at my polling station this November. (My Democratic counterpart will be assistant election judge.) I have read with interest the stories about voting machine hacking, and I want advice from those of you who are experts on what to watch for to make sure there is no fraudulent activity at my precinct during the election. What activities should I look for? Keep in mind my restrictions: I will be at a table in the front of the room with the voter rolls signing people in, I can only approach the voting machines if a voter asks a question or if I have strong reason to believe there is fraudulent activity, the last thing I need is for someone to say the Republicans are trying to keep people from voting! And finally, although each station and voter will be visible from my seat each machine has 'blinders' around it so I will most likely not be able to see the hands of each voter while they are at the station. Thank you in advance for all suggestions."

Coryoth writes "The BBC is reporting on a recent study in the UK that found that the difficulty of high school level math exams has declined. The study looked at mathematics from 1951 through to the present and found that, after remaining roughly constant through the 1970s and 1980s, the difficulty of high school math exams dropped precipitously starting in the early 1990s. A comparison of exams is provided in the appendix of the study. Are other countries, such as the US, noticing a similar decline in mathematics standards?" Readers with kids in school right now may have the best perspective on changes in both teaching and testing methods -- what have you noticed?

theper writes "A little over a week from now, I have a dinner planned with an old friend and a member of the Swedish parliament. I know a thing or two about the internet, piracy and file sharing, and she's asked for my advice on new legislation on that subject. Her (and her party's) stance is not very controversial: Rights holders must get paid one way or another, and at the same time record companies has to change their old business models and must do more to keep up with technology. With this kept in mind, what advice should I give her?"

The corporate overlords at SourceForge asked me to name a Slashdot category for their upcoming Community Choice Awards and to let you guys select the winner. I have named my category "Most Likely to be Shut Down by a Government Agency." We're going to run this like we do an Ask Slashdot call for questions — post your nominations into the comments here. Use moderation to send up good ideas. In the upcoming days we'll post another story where you can vote on the actual winner. Nominations need to include the project name, a link to some sort of official website, and a paragraph of why you think they deserve to win. The project that wins will gain fame, notoriety, and maybe a cease and desist order that they could print out and frame if they had that kind of time.

An anonymous reader writes "In six months' time, I am packing up and moving from Australia (Melbourne) to Canada (Vancouver). I'm a qualified network engineer. What I want to know is, what sort of quirks and tricks I am going to have to get used to in the Canadian job market? I'm used to Australian recruiters, and all the hoops you have to jump through, but Canada may have different hoops. I've tried contacting recruiters directly for information but they don't really give out much, as I am not actually in the country yet and therefore not worth their time. Is anyone willing to share their experiences on making the big move from country to country?"
