An anonymous reader writes: I do some contract work on the side, and am helping a client set up a new point-of-sale system. For the time being, it's pretty simple: selling products, keeping track of employee time, managing inventory and the like. However, it requires a small network because there are two clients, and one of the clients feeds off of a small SQL Express database from the first. During the setup, the vendor disabled the local firewall, and in a number of emails back and forth since (with me getting more and more aggravated) they went from suggesting that there's no need for a firewall, to outright telling me that's just how they do it and the contract dictates that's how we need to run it. This isn't a tremendous deal today, but with how things are going, odds are there will be e-Commerce worked into it, and probably credit card transactions... which worries the bejesus out of me.
So my question to the Slashdot masses: is this common? In my admittedly limited networking experience, it's been drilled into my head fairly well that not running a firewall is lazy (if not simply negligent), and to open the appropriate ports and call it a day. However, I've seen forum posts here and there with people admitting they run their clients without firewalls, believing that the firewall on their incoming internet connection is good enough, and that their client security will pick up the pieces. I'm curious how many real professionals do this, or if the forum posts I'm seeing (along with the vendor in question) are just a bunch of clowns.
Qbertino (265505) writes I've been musing about a security setup to allow my coworkers/users access to files from the outside. I want security to be a little safer than pure key- or password-based SSH access, and some super-expensive RSA Token setup is out of question. I've been wondering whether there are any feasible and working FOSS and open hardware-based security token generator projects out there. It'd be best with ready-made server-side scripts/daemons. Perhaps something Arduino or Raspberry Pi based? Has anybody tried something like this? What are your experiences? What do you use? How would you attempt an open hardware FOSS solution to this problem?
First time accepted submitter baka_toroi (1194359) writes I got a Tungsten E2 from a friend and I wanted to give it some life by programming for it a little bit. The main problem I'm bumping up against is that HP thought it would be awesome to just shut down every single thing related to Palm OS development. After Googling a lot I found out CodeWarrior was the de facto IDE for Palm OS development... but I was soon disappointed as I learned that Palm moved from the 68K architecture to ARM, and of course, CodeWarrior was just focused on Palm OS 4 development.
Now, I realize Palm OS 4 software can be run on Palm OS 5, but I'm looking to use some of the 'newer' APIs. Also, I have the Wi-fi add-on card so I wanted to create something that uses it. I thought what I needed was PODS (Palm OS Development Suite) but not only I can't find it anywhere but also it seems it was deprecated during Palm OS's lifetime. It really doesn't help the fact that I'm a beginner, but I really want to give this platform some life. Any general tip, book, working link or even anecdotes related to all this will be greatly appreciated.
UrsaMajor987 (3604759) writes I have a Asus Transformer tablet that I dropped on the floor. There is no obvious sign of damage but It will no longer boot. Good excuse to get a newer model. I intend to sell it for parts (it comes with an undamaged keyboard) or maybe just toss it. I want to remove all my personal data. I removed the flash memory card but what about the other storage? I know how to wipe a hard drive, but how do you wipe a tablet? If you were feeling especially paranoid, but wanted to keep the hardware intact for the next user, what would you do?
New submitter Christian Gainsbrugh (3766717) writes I work at a company that is currently transitioning all our servers into the cloud. In the interim we have half a rack of server space in a great datacenter that will soon be sitting completely idle for the next few months until our lease runs out. Right now the space is occupied by around 8 HP g series servers, a watchguard xtm firewall, Cisco switch and some various other equipment. All in all there are probably around 20 or so physical XEON processors, and probably close to 10 tb of storage among all the machines. We have a dedicated 10 mbs connection that is burstable to 100mbs.
I'm curious what Slashdot readers would do if they were in a similar situation. Is there anything productive that could be done with these resources? Obviously something revenue generating is great, but even if there is something novel that could be done with these servers we would be interested in putting them to good use.
gunner_von_diamond (3461783) happened upon Ask Slashdot: Experiences with Laser Eye Surgery from ten years ago, and asks: I was just reading a story on /. from 10 years ago about Lasik Eye Surgery. Personally, I've had Lasik done and loved every single part of the surgery. I went from wearing contacts/glasses every day to having 20/15 vision! In the older post, everyone seemed to be cautious about it, waiting for technical advances before having the surgery. Today, the surgery is fairly inexpensive [even for a programmer :) ], takes about 10-15 minutes, and I recovered from the surgery that same day. So my question is: what is holding everyone else back from freeing themselves from contacts and glasses?
An anonymous reader writes: Yesterday, word came down that Microsoft was starting to lay off some 18,000 workers. As of June 5th, Microsoft reported a total employee headcount of 127,005, so they're cutting about 15% of their jobs. That's actually a pretty huge percentage, even taking into account the redundancies created by the Nokia acquisition. Obviously, there's an upper limit to how much of your workforce you can let go at one time, so I'm willing to bet Microsoft's management thinks thousands more people aren't worth keeping around. How many employees does Microsoft realistically need? The company is famous for its huge teams that don't work together well, and excessive middle management. But they also have a huge number of software projects, and some of the projects, like Windows and Office, need big teams to develop. How would we go about estimating the total workforce Microsoft needs? (Other headcounts for reference: Apple: 80,000, Amazon: 124,600, IBM: 431,212, Red Hat: 5,000+, Facebook: 6,800, Google: 52,000, Intel: 104,900.)
An anonymous reader writes: My niece, who is graduating from high school, has asked me for some career advice. Since I work in data processing, my first thought was to recommend a degree course in computer science or computer engineering. However, after reading books by Jeremy Rifkin (The Third Industrial Revolution) and Ray Kurzweil (How to Create a Mind), I now wonder whether a career in information technology is actually better than, say, becoming a lawyer or a construction worker. While the two authors differ in their political persuasions (Rifkin is a Green leftist and Kurzweil is a Libertarian transhumanist), both foresee an increasingly automated future where most of humanity would become either jobless or underemployed by the middle of the century. While robots take over the production of consumer hardware, Big Data algorithms like the ones used by Google and IBM appear to be displacing even white collar tech workers. How long before the only ones left on the payroll are the few "rockstar" programmers and administrators needed to maintain the system? Besides politics and drug dealing, what jobs are really future-proof? Would it be better if my niece took a course in the Arts, since creativity is looking to be one of humanity's final frontiers against the inevitable Rise of the Machines?
Watches that do more than tell the time have been around for a long time. (And in fiction, James Bond, Dick Tracey, and Michael Knight all had notably high-tech watches.)
The new smart watches from Samsung and LG, without a phone connected via Bluetooth as backhaul, can still serve to show the time and to serve as alarms (and Samsung's can measure your pulse, too), but all the magic features (like searching by voice via the watch) do require a connection. They can't play MP3s or take pictures on their own, and they don't have built-in GPS. Even so, compared to the polarizing Google Glass, the new breed of smart watches are wearables that probably are an easier sell, even if this far the trend has been to replace watches with smart phones. (Android Wear has gotten a lot of attention, but Microsoft has their own upcoming, and Apple almost certainly does, too.) Are you interested in a smart watch, and if so, what uses do you want it for? If they have no appeal to you now, are there functions that would make you change your mind on that front?
grahamsaa writes: Like many others in IT, I sometimes have to do server maintenance at unfortunate times. 6AM is the norm for us, but in some cases we're expected to do it as early as 2AM, which isn't exactly optimal. I understand that critical services can't be taken down during business hours, and most of our products are used 24 hours a day, but for some things it seems like it would be possible to automate maintenance (and downtime).
I have a maintenance window at about 5AM tomorrow. It's fairly simple — upgrade CentOS, remove a package, install a package, reboot. Downtime shouldn't be more than 5 minutes. While I don't think it would be wise to automate this window, I think with sufficient testing we might be able to automate future maintenance windows so I or someone else can sleep in. Aside from the benefit of getting a bit more sleep, automating this kind of thing means that it can be written, reviewed and tested well in advance. Of course, if something goes horribly wrong having a live body keeping watch is probably helpful. That said, we do have people on call 24/7 and they could probably respond capably in an emergency. Have any of you tried to do something like this? What's your experience been like?

An anonymous reader writes "We all know somebody who changes jobs like changing clothes. In software development and IT, it's getting increasingly hard to find people who have been at their job for more than a few years. That's partly because of tech companies' bias for a young work force, and partly because talented people can write their own ticket in this industry. Thus, I put the question to you: how often should you be switching jobs? Obviously, if you find the perfect company (full of good people, doing interesting things, paying you well), your best bet is to stay. But that's not the reality for most of the workforce. Should you always be keeping an eye out for new jobs? Is there a length of time you should stick around so you don't look like a serial job-hopper? Does there come a point in life when it's best to settle down and stick with a job long term?"
tobiasly (524456) writes I run a few websites which are occasionally the target of bogus DMCA takedown requests. Even a cursory look at these requests would reveal that the content these requests try to have removed are not even eligible for copyright (for example, someone named "John Smith" decides he wants to have every instance of his name removed from the internet, so he claims he has a copyright on "John Smith", and the comment section of my website has that name somewhere.) I'm guessing most webmasters of sites with significant traffic face this problem, but I'm having difficulty finding information on domain registrars' and hosting providers' DMCA response policies. Most seem to over-react and require an official counter-response. I'm worried I'll miss one of these someday and find that my entire domain was suspended as a result. Both my domain registrar and hosting provider have forwarded these notices in the past. I'm also worried that they're forwarding my response (including personal details) to the original complainant. Which domain registrars and hosting providers have you found who handle these complaints in a reasonable manner, and filter out the ones that are obviously bogus? Which ones have a clearly stated policy regarding these requests, and respect the site owner's privacy? Some of these domains are .us TLD, which unfortunately will limit my choice to U.S.-based companies.

What compelling arguments can you give that would help an old company change its standard if that company is pretty set in its ways?"
New submitter faderrider (3726665) writes I work in the healthcare design industry and our firm is looking to get away from using paper during our design meetings. My first thought was to load our reports and plans on a tablet, bring a half dozen or so tablets for attendees and somehow create a local ad hoc network that would allow them to view my desktop. A little more thinking brought me to consider the value of attendees being able to mark up documents on their own, or take control of what is being viewed to talk through ideas. Is anyone else out there doing something like this and if so what are you implementing? Specifically the challenges i see are creating the local network, establishing share/control relationships between tablets and managing any documentation markups attendees may make during the meeting. I am also looking at the Samsung 10.1 as the hardware but would be interested in any recommendations. I can also provide, most of the time, web access via my phone but would prefer not to rely on a service like WebEx or JoinMe.
adelayde (185757) writes "In my day job, I work on a web based service with a lot of legacy code written in that older (and some may say venerable) web-scripting language, Perl. Although we use Modern Perl extensions such as Moose, the language just seems to be ossifying and we're wanting to move to a more up-to-date and used language for web applications, or even an entire framework, to do new development. We're still planning to support the legacy code for a number of years to come; that's unavoidable. This is a fairly big project and it's mission critical to the business. The thing we're afraid of is jumping onto something that is too new and too buzzy as we'd like to make a technology decision that would be good at least for the next five years, if not more, and today's rising star could quite easily be in tomorrow's dustbin. What language and/or framework would you recommend we adopt?"
An anonymous reader writes I'll be returning to North America for July for the first time in a few years, and I'm curious how the phone carrier market compares with the rest of the world. My last time in the U.S., I had to pick up a disposable phone with all kinds of unnecessary environmental waste (charger, packaging, etc.), and *still* had to register it with another domestic (!) phone number and credit card. I don't think I could get a SIM card there without a contract. Anywhere else I travel, picking up a new SIM card with pre-loaded credit is trivially easy. In my last trip to the UK, I just put GBP 10 into a vending machine at the airport and picked up a loaded SIM card for my phone which aldready has my contacts and settings. No ID, no name, no hassle. What are the best options for me in North America (U.S. *and* Canada)?

Qbertino (265505) writes I've been rummaging around on old backups and cleaning out my stuff and have once again run into my expert-like paranoid backups and keepsakes from back in the days (2001). I've got, among other things, a full set of Debian 3 CDs, an original StarOffice 6.0 CD including a huge manual in mint condition, Corel Draw 9 for Linux, the original box & CDs — yes it ran on a custom wine setup, but it ran well, I did professional design and print work with it.
I've got more of other stuff lying around, including the manuals to run it. Loki Softs Tribes 2, Kohan, Rune, and the original Unreal Tournament for Linux have me itching too. :-)
I was wondering if it would be possible to do an old 2001ish setup of a Linux workstation on some modern super cheap, super small PC (Raspberry Pi? Mini USB PC?), install all the stuff and give it a spin. What problems should I expect? VESA and Soundblaster drivers I'd expect to work, but what's with the IDE HDD drivers? How well does vintage Linux software from 2003 play with todays cheap system-on-board MicroPCs? What's with the USB stuff? Wouldn't the install expect the IO devices hooked on legacy ports? Have you tried running 10-15 year old Linux setups on devices like these and what are your experiences? What do you recommend?
An anonymous reader writes: I don't wear a watch. I never have. So, to me, the push for smart watches has always been a non-starter. But I was discussing with friends some of the features of Android Wear that Google demonstrated at the I/O conference today, and it got me wondering: what set of features would be required for a smartwatch to become viable? Obviously, this is different for everybody — millions of people wear regular watches even though they could easily pull out their phone and check the time there. Any smartwatch can also tell time, but it has advantages (apps that do other things), and disadvantages (needs charging). Clearly, there are some functions for which it's useful to have an object strapped to your wrist, even if that function could be served by the device in your pocket. Telling time is one, and lots of people use sundry fitness doo-dads to measure exercise. It makes sense to me that checking the weather forecast would fall into this category, and perhaps checking notifications. (Conversely, other functions do not translate at all, like taking photos or playing games.) Thus, two questions: if you already wear a watch, what would it take for a smartwatch to replace it? If you don't wear a watch, what features would motivate you to get one?
