We're now engaged in a significant upgrade to our IT systems and we have a clash: the IT team leader wants to run network cable in trays hanging from the ceiling so all the client computers have high-speed access to the new servers; the guy in charge of the office design wants to keep things looking clean and the cable trays don't fit the bill. We're in a building made entirely of bricks and concrete, so we lack some of the between-the-wall spaces that are used in other settings. Any suggestions for beautiful cable trays or other alternatives?"

An anonymous reader writes "A week ago, Slashdot was asked, "How do you protect your privacy?" The question named many different ways privacy is difficult to secure these days, but almost all of the answers focused on encrypting internet traffic. But what can you do about your image being captured by friends and strangers' cameras (not to mention drones, police cameras, security cameras, etc.)? How about when your personal data is stored by banks and healthcare companies and their IT department sucks? Heck; off-the-shelf tech can see you through your walls. Airport security sniffs your skin. There are countless other ways info on you can be collected that has nothing to do with your internet hygiene. Forget the NSA; how do you protect your privacy from all these others? Can you?"

An anonymous reader writes "Over the last couple years, I have taught myself the basic concepts behind Computational Neuroscience, mainly from the book by Abbott and Dayan. I am not currently affiliated with any academic Neuroscience program. I would like to take a DIY approach and work on some real world problems of Computational Neuroscience. My questions: (1) What are some interesting computational neuroscience simulation problems that an individual with a workstation class PC can work on? (2) Is it easy for a non-academic to get the required data? (3) I am familiar with (but not used extensively) simulators like Neuron, Genesis etc. Other than these and Matlab, what other software should I get? (4) Where online or offline, can I network with other DIY Computational Neuroscience enthusiasts? My own interest is in simulation of Epileptogenic neural networks, music cognition networks, and perhaps a bit more ambitiously, to create a simulation on which the various Models of Consciousness can be comparatively tested."

diab0lic writes "I have recently come into the situation where I need to run cloud computing on demand for my research. Amazon's EC2 Spot Instances are an ideal platform for this as I can requisition an appropriate instance for the given experiment {high cpu, high memory, GPU instance} depending on its needs. However I currently spin up the instance manually, set it up, run the experiment, and then terminate manually. This gets tedious monitoring experiments for completion, and I incur unnecessary costs if a job finishes while I'm sleeping, for example. The whole thing really should be automated. I'm looking for a workflow somewhat similar to this:

1. Manually create Amazon machine image (AMI) for experiment.
2. Issue command to start AMI on specified spot instance type.
3. Automatically connect EBS to instance for result storage.
4. Automatically run specified experiment, bonus if this can be parameterized.
5. Have AMI automatically terminate itself upon experiment completion.

Something like docker that spun up on-demand spot instances of a specified type for each run and terminated said instance at run completion would be absolutely perfect. I also know HTCondor can back onto EC2 spot instances but I haven't really been able to find any concise information on how to set up a personal cloud — I also think this is slight overkill. Do any other Slashdot users have similar problems? How did you solve it? What is your workflow? Thanks!"

First time accepted submitter hurwak-feg writes "I am in the market for a new IT (software development or systems administration) job for the first time and several years and noticed that many postings have very specific requirements (i.e. specific models of hardware, specific software versions). I don't understand this. I like working with people that have experience with technologies that I don't because what they are familiar with might be a better solution for a problem than what I am familiar with. Am I missing something or are employers making it more difficult for themselves and job seekers by rejecting otherwise qualified candidates that don't meet a very specific mold. Is there a good reason for being extremely specific in job requirements that I am just not seeing?"

And while the WSJ will try to slap you back to reality with a story on The Dirty Secret of Black Friday 'Discounts', it's still hard not to get jazzed over the prospect of picking up an iPad Mini w/$100 gift card for $299 (Walmart), a 16GB Nexus 7 for $199 (Staples), or a 32GB Microsoft Surface for $199.99 (Best Buy). So, if you're playing the game this year — either online or in-person (hey, what could go wrong?), — what are your top tech picks for Black Friday? Any strategy for improving your odds of getting them?"

goodminton writes "I'm research the long-term consistency and reproducibility of math results in the cloud and have questions about floating point calculations. For example, say I create a virtual OS instance on a cloud provider (doesn't matter which one) and install Mathematica to run a precise calculation. Mathematica generates the result based on the combination of software version, operating system, hypervisor, firmware and hardware that are running at that time. In the cloud, hardware, firmware and hypervisors are invisible to the users but could still impact the implementation/operation of floating point math. Say I archive the virutal instance and in 5 or 10 years I fire it up on another cloud provider and run the same calculation. What's the likelihood that the results would be the same? What can be done to adjust for this? Currently, I know people who 'archive' hardware just for the purpose of ensuring reproducibility and I'm wondering how this tranlates to the world of cloud and virtualization across multiple hardware types."

50000BTU_barbecue writes "I made a comment a few days ago in a story basically saying the oscilloscope is dead. While that's a bit dramatic, I've found that over the last 20 years my oscilloscopes have been 'on' less and less. Instead, I use a combination of judicious voltage measurements, a logic analyzer and a decent understanding of the documentation of the gadget I'm working on. Stuff is just more and more digital and microcontroller-based, or just so cheap yet incredibly integrated that there's no point in trying to work on it. (I'm thinking RC toys for example. Undocumented and very cheap. Doesn't work? Buy another.) While I still do old-school electronics like circuit-level troubleshooting (on old test gear), that's not where the majority of hobbyists seem to be. Yet one thing I keep hearing is how people want an oscilloscope to work on hardware. I think it's just not that necessary anymore. What I use most are two regulated DC lab supplies, a frequency counter, a USB logic analyzer, a USB I2C/SPI master, and a USB-RS-232 dongle. That covers a lot of modern electronics. I have two oscilloscopes, a 100MHz two-channel stand-alone USB unit and a 1960s analog plug-in-based mainframe that is a '70s hacker dream scope. But I rarely use them anymore. What equipment do hardware folks out there use the most? And would you tell someone trying to get into electronics that they need a scope?"

jones_supa writes "One of the most important measuring sticks for the success of any software is how long a user keeps it installed after first trying it. Intel has an article about some of the most common reasons users abandon software. Quoting: 'Apps that don’t offer anything helpful or unique tend to be the ones that are uninstalled the most frequently. People cycle through apps incredibly quickly to find the one that best fits their needs. ... A lot of apps have a naturally limited lifecycle; i.e., apps that are centered around a movie release or an app that tracks a pregnancy, or an app that celebrates a holiday. In addition, apps with limited functionality, for example, “lite” games that only go so far, are uninstalled once the user has mastered all the levels.' Some of the common factors they list include: lengthy forms, asking for ratings, collecting unnecessary data, user unfriendliness, unnecessary notifications and, of course, bugs. Additionally, if people have paid even a small price for the app, they are more committed to keep it installed. So, what makes you uninstall a piece of software?"

Traditional advice isn't relevant to casual, less hierarchical companies — I don't have to hold my tongue when someone is wrong or worry about formalities. But I do need to connect with people professionally, since my team members and managers decide my perf and advancement.

An anonymous reader writes "I've recently been charged with updating our existing serial console access tools. We have 12 racks of servers each with a console server in it (OpenGear, ACS, and a few others). Several of these systems host virtual machines which are also configured to have 'serial' management (KVM, virt serial). In total it comes to about 600 'systems.' All the systems also have remote power management (various vendors). Right now our team has a set of home grown scripts and a cobbled together database for keeping this all together. Today any admin can simply ssh into the master, run 'manage hostname console' and automatically get a serial console or run 'manage hostname power off' to cut the power to a system. I'd rather use some tools with more of a community than just the 4 of us. What tool(s) should I move my group onto for remote serial/power management?"

First time accepted submitter renzema writes "I'm looking for a way to do near-site backups — backups that are not on my physical property, but with a hard drive still accessible should I need to do a restore (let's face it — this is where cloud backup services are really weak — 1 TB at 3-4mb downloads just doesn't cut it). I've tried crashplan, but that requires that someone has a computer on all the time and they don't ship hard drives to Sweden. What I want is to be able to back up my Windows and Mac to both a local disk and to a disk that I own that is not on site. I don't want a computer running 24x7 to support this — just a router or NAS. I would even be happy with a local disk that is somehow mirrored to a remote location. I haven't found anything out there that makes this simple. Any ideas?"

An anonymous reader writes "Almost three years ago, I started looking for a cloud storage service. Encryption and the "zero-knowledge" concept were not concerns. Frankly, after two weeks testing services, it boiled down to one service I used for almost 2 years. It was perfect — in the technical sense — because it simply works as advertised and is one of the cheapest for 500GB. But this year, I decided changing that service for another one, that would encrypt my files before leaving my machine. Some of these services call themselves 'zero-knowledge' services, because (as they claim) clear text does not leave your host: they only receive encrypted data — keys or passwords are not sent. I did all testing I could, with the free bit of their services, and then, chose one of them. After a while, when the load got higher (more files, more folders, more GB...), my horror story began. I started experiencing sync problems of all sorts. In fact, I have paid for and tested another service and both had the same issues with sync. Worse, one of them could not even handle restoring files correctly. I had to restore from my local backup more than once and I ended up losing files for real. In your experience, which service (or services) are really able to handle more than a hundred files, in sync within 5+ hosts, without messing up (deleting, renaming, duplicating) files and folders?"
