Ask Slashdot: How To Evacuate a Network 331

Posted by timothy from the bring-the-fire-extinguishers dept.
First time accepted submitter gpowers writes "I am the IT Manager for Shambhala Mountain Center, near Red Feather Lakes, Colorado. We are in the pre-evacuation area for the High Park Fire. What is the best way to load 50+ workstations, 6 servers, IP phones, networking gear, printers and wireless equipment into a 17-foot U-Haul? We have limited packing supplies. We also need to spend as much time as possible working with the fire crew on fire risk mitigation."

Ask Slashdot: Instead of a Laptop, a Tiny Computer and Projector? 339

Posted by timothy from the trade-off-is-convenience dept.
rover42 writes "I travel a lot, usually on a tight budget and often on airlines with tight luggage weight restrictions and high fees for going over, so traveling light is very important to me. So is connecting to the net when traveling, which creates a conflict. I do not trust machines in Internet cafes and my laptop adds significant weight & bulk to my luggage. I could buy a small netbook or a MacBook Air, but is there another choice? There are quite a few tiny computers available, Raspberry Pi and the like. Alone, they don't solve my problem because you need a screen and that is at least as heavy as a laptop. However, there are also quite a few tiny projectors. Would a tiny computer plus a tiny projector do the trick? Which ones? All I need for software is some open source Unix (any *BSD or Linux distro should be fine, or even Minix), a browser and an editor. I don't need large storage or a fast CPU. Has anyone done something like this? Does anyone have a recommendation for either the computer or the projector?"

Ask Slashdot: What's Your Take On HTTPS Snooping? 782

Posted by timothy from the note-from-the-principal's-office dept.
First time accepted submitter jez9999 writes "I recently worked for a relatively large company that imposed so-called transparent HTTPS proxying on their network. In practice, what this means is that they allow you to use HTTPS through their network, but it must be proxied through their server and their server must be trusted as a root CA. They were using the Cisco IronPort device to do this. The "transparency" seems to come from the fact that they tend to install their root CA into Internet Explorer's certificate store, so IE won't actually warn you that your HTTPS traffic may be being snooped on (nor will any other browser that uses IE's cert store, like Chrome). Is this a reasonable policy? Is it worth leaving a job over? Should it even be legal? It seems to me rather mad to go to huge effort to create a secure channel of communication for important data like online banking, transactions, and passwords, and then to just effectively hand over the keys to your employer. Or am I overreacting?"

Ask Slashdot: Security Digests For the Home Network Admin? 123

New submitter halcyon1234 writes "I'm currently cutting the webhost cord, and setting up a simple webserver at home to host a couple hobby websites and a blog. The usual LAMP stuff. I have just enough knowledge to be dangerous; I know how to get everything set up and get it up to date, but not enough to be sure I'm not overlooking common, simple security configurations. And then there's the issue of new vulnerabilities being found that I'm not even aware of. The last thing I want is to contribute to someone's botnet or spam relay. What readings/subscriptions would you recommend for security discussions/heads up? Obviously I already read (too much) Slashdot daily, which I credit for hearing about some major security issues. Are there any RSS feeds or mailing lists you rely on for keeping up to date on security issues?"

Ask Slashdot: What's Your Beef With Windows Phone? 1027

Posted by timothy from the gave-baby-to-dingo dept.
First time accepted submitter occasional_dabbler writes "Reviews by 'commentators' such as this one predict certain doom for both Nokia and Microsoft on the basis of the OS being a failure, yet whenever the Lumia handsets are reviewed in the mainstream press they are often highly praised. Windows phone is an immature OS, certainly, but it does pretty much everything you need in a smartphone, is getting better with each update and it is beautiful. I have a Lumia 800, and now I'm used to how it and the WP OS works I find it a painful process to go back to an Android or iPhone for some obscure app not yet supported on WP. WP gave me the same feeling I got when I bought my first iBook, fired up OS X 10.1 and realized I had just been shifted up a decade. So why so serious? What do Slashdotters who have really tried WP think of it?"

Ask Slashdot: Why Are Hearing Aids So Expensive? 629

Posted by Soulskill from the what-the-market-will-bear dept.
solune writes "You can get a tablet these days for a few hundred dollars, and laptops for a few hundred more. Gaming consoles, TVs, and smartphones are all available for under a thousand bucks. Yet, a decent hearing aid for my mom will go upwards of $3000! With ever-shrinking electronic components, better capabilities, and technological advancements, not to mention the rapidly increasing potential user base, I would think quality hearing aids should be coming in a lot cheaper than what we can find. Adding fuel to my fire is that a hearing aid will greatly improve my mom's life — not to mention the lives of millions of others out there. Currently, she suffers from frustration and isolation with having to ask people to 'speak up', and nodding her head to things her kids and grandkids say. We've tried the cheapies, and they're fraught with problems. So, can someone tell me why a hearing aid should be so expensive?"

alexbgreat writes "What do you think is the best set of head-mounted loudspeakers for the money, with a cost of less than $50? Here are some featuresthat would be stupendous to have (in descending order of importance): noise isolation (not cancellation), flat/near flat response (I need to be able to hear bass, but I don't need my eardrums blown out), long-term comfort (earbuds usually hurt for me), and durability. Over-ear is preferred to anything on- or in-ear. Boom mics are permissible, as I may well use it as a broadcast intercom headset."

Ask Slashdot: Ambitious Yet Ethical Software Jobs? 559

Posted by timothy from the all-depends-on-what-your-ethics-say dept.
First time accepted submitter hwaccaly writes "I'm a mid-career developer with a fair amount of experience working on data-intensive, mathematically ambitious software projects for fun — things like physics and systems simulations, written mostly in CUDA, targeted at Tesla GPUs and small clusters. Ideally, I'd like to get paid for this kind of work, but I've found little call for these skills outside of the financial and defense industries. My conscience won't allow me to accept money from either. The medical/pharmaceutical industries undoubtedly require complex software, but the unavoidable animal testing at the end of the pipeline probably lifts its body count higher even than the defense industry's. And academia pays in degrees, not dollars. So what's left? Do any ethical businesses have a pressing need for high-performance computing, or is it basically a hobbyist niche?"

In recent years, I've worked for computer software vendors doing pre-sales support generally for infrastructure products including applications, app servers, integration with Java based messaging and ESB product and most recently a Business Rules product. I was laid off recently due to a restructuring and am now trying to figure out the next phase. With the WIA displaced worker grants now available I am attempting to figure out what training would be good to pursue. I am hearing that 'the Cloud' is the next big thing, but I'm also looking into increasing my development skills with a current language. I wonder what the readers might suggest for new directions."

HappyDude writes "I've been asked to manage a department in our IT group. It's comprised of UNIX, VMWare, Citrix, EMC and HP SAN Admins, Technicians and Help Desk personnel. The group covers the spectrum in years of experience. I am a 20-year Admin veteran of Engineering and Health Care IT systems including UNIX, Oracle DBA, Apache HTTP/Tomcat, WebSphere, software design plus other sundry jack-of-all-trades kinds of stuff. Although I consider myself a hack at most of those trades, I'm reasonably good at any one of them when I'm submerged. I also have 10 years of Project Management experience in Engineering and Health Care related IT organizations. I do have formal PM training, but haven't bothered to seek credentialing. I'm being told that I'll be worth less to the organization as a supervisor than what I'm making now, but the earning potential is greater if I accept the management position. Out of the kindness of their hearts, they're offering to start me in the new position at the same wage I'm currently making. Does this make any sense, Slashdot? " Read on for further details.

Ask Slashdot: Getting a Tech Job With Skills But No Formal Degree? 266

fmatthew5876 writes "I have a friend who graduated with a degree in philosophy and sociology. He has been spending a lot of his spare time for the last couple years learning system administration and web development. He has set up web servers, database servers, web proxies and more. He has taught himself PHP, MySQL, and how to use Linux and openBSD without any formal education. I believe that if given the chance with an entry level position somewhere and a good mentor he could really be a great Unix admin, but the problem is that he doesn't have a degree in computer science or any related field. He is doing stuff now that a lot of people I graduated with (I was a CS major) could not do when they had a bachelor's degree. Does Slashdot have any advice on what my friend could do to build up his resume and find a job? I know a lot of people think certifications are pretty useless or even harmful, but in his case do you think it would be a good idea?"

My own memories of chemistry teaching in school are of disappointment, a shocking waste of everyone's time and extreme boredom. I think there must be a better way.

I've had success on smaller projects with the Soekris offerings but they are suboptimal for large-scale deployment due to their single-board non-redundant design (eg., single power supply, lack of backup 'controller'). What is the closest thing to a modular Linux-capable platform with some level of hardware redundancy and substantial bus/backplane throughput?"

Ask Slashdot: Reasonable Immigration Policy For Highly-Trained Workers? 357

davidwr writes "What are a reasonable temporary-worker or immigration-visa rules to apply to workers whose skills would quickly net them a 'top 20th percentile wages' job (about $100,000) in the American workplace, if they were allowed to work in the country? Should the visa length be time-limited? Should it provide for a path to permanent residency? Should the number be limited, and if so, how should we decide what the limit should be? The people affected are already likely eligible for special work-permit programs, but these programs may have quotas, time limits, prior-job-offer-requirements, and other restrictions. I'm asking what Slashdotters think the limits and restrictions, if any, should be. (Let's assume any policy to keep out criminals and spies remains as-is.)"

My question is, what's available? Are people working on mobile-programming in this way? Are there hybrid standing workstations which allow me to take advantage of pacing-enabled programming?"

An anonymous reader writes "Here's a scenario: you are on a vacation trip for a couple of weeks — on the road. Lots of pictures — 2-300 per day. Maybe some text files with short notes etc. You have a camera with Eye-Fi, a PC, and a phone with WiFi and 3G. Files ends up on the PC (mobile storage), phone provides Internet connectivity. Now, if you wanted to upload all files pretty much as you go — given spotty access to Internet over G3 and WiFi — what would be the best way to do that automatically; set-it-and-forget-it style? I would like them to end up on my own server. rsync script? ownCloud? Some BitTorrent setup? Other? I'm thinking of interrupted file transfers due to no network, re-starts etc. And I would not want to lose any files; including scenarios where files gets deleted locally — that should not result in files getting automatically deleted on the server as well. Sure; I could perhaps use something like Dropbox but that would take the fun out of it."

New submitter sdoca writes "I am a Java developer and for the past number of years I have mainly been working on server side code. I have an idea for a webpage/application that I would like to develop. For the general public, it will be a site where they can view upcoming events, filter them by type, date etc. and view details of events they're interested in. There will also be an admin section to the app where organizations who want to post their events can log in and set them up. In the long term, writing a view-only version as an Apple and/or Android app is on the radar, but I want to focus on the generic web app for now. I'm not sure what languages/frameworks to look at using for the webpage portion of my project. Many (many!) years ago, I wrote some applets. After that I did some work in WebObjects and after that I tinkered with Wicket. I have no experience with PHP and would like to stay in my Java comfort zone as much as possible, but want to use the right tool. I'm concerned about browser compatibility issues. Chrome didn't exist when I last did web page development. I'm looking for good resources (books, internet) that will guide me through the potential issues and your recommendations for a web development framework."
