Ask Slashdot: Knowledge Management Systems? 9

Tom writes: Is there an enterprise level equivalent of Semantic MediaWiki, a Knowledge Management System that can store meaningful facts and allows queries on it? I'm involved in a pretty large IT project and would like to have the documentation in something better than Word. I'd like it to be in a structured format that can be queried, without knowing all the questions that will be asked in the future. I looked extensively, and while there are some graphing or network layout tools that understand predicates, they don't come with a query language. SMW has both semantic links and queries, but as a wiki is very free-form and it's not exactly an Enterprise product (I don't see many chances to convince a government to use it). Is there such a thing?

Ask Slashdot: Where Can I Find "Nuts and Bolts" Info On Cookies & Tracking Mechanisms? 83

New submitter tanstaaf1 writes: I was thinking about the whole tracking and privacy train-wreck and I'm wondering why specific information on how it is done, and how it can be micromanaged or undone by a decent programmer (at least), isn't vastly more accessible? By searching, I can only find information on how to erase cookies using the browser. Browser level (black box) solutions aren't anywhere near good enough; if it were, the exploits would be few and far between instead everywhere everyday. Read below for the rest of tanstaaf1's question.

Ask Slashdot: What Is Your Most Awesome Hardware Hack? 249

An anonymous reader writes: Another Slashdotter once asked what kind of things someone can power with an external USB battery. I have a followup along those lines: what kind of modifications have you made to your gadgets to do things that they were never meant to do? Consider old routers, cell phones, monitors, etc. that have absolutely no use or value anymore in their intended form. What can you do with them? Have you ever done something stupid and damaged your electronics?

Ask Slashdot: Best Country For Secure Online Hosting? 112

An anonymous reader writes: I've recently discovered that my hosting company is sending all login credentials unencrypted, prompting me to change providers. Additionally, I'm finally being forced to put some of my personal media library (songs, photos, etc.) on-line for ready access (though for my personal consumption only) from multiple devices and locations... But I simply can't bring myself to trust any cloud-service provider. So while it's been partially asked before, it hasn't yet been answered: Which country has the best on-line personal privacy laws that would made it patently illegal for any actor, state, or otherwise, to access my information? And does anyone have a recommendation on which provider(s) are the best hosts for (legal) on-line storage there?

Ask Slashdot: Is the Gap Between Data Access Speeds Widening Or Narrowing? 91

New submitter DidgetMaster writes: Everyone knows that CPU registers are much faster than level1, level2, and level3 caches. Likewise, those caches are much faster than RAM; and RAM in turn is much faster than disk (even SSD). But the past 30 years have seen tremendous improvements in data access speeds at all these levels. RAM today is much, much faster than RAM 10, 20, or 30 years ago. Disk accesses are also tremendously faster than previously as steady improvements in hard drive technology and the even more impressive gains in flash memory have occurred. Is the 'gap' between the fastest RAM and the fastest disks bigger or smaller now than the gap was 10 or 20 years ago? Are the gaps between all the various levels getting bigger or smaller? Anyone know of a definitive source that tracks these gaps over time?

Ask Slashdot: Simple, Cross-Platform Video Messaging? 115

DeathToBill writes: I spend a lot of time away from my kids (think months at a time) who are aged 3-8. I keep in touch with them by Skype, but the young ones are not really old enough to concentrate on it and we're often in quite different timezones, so it's not often it can be very spontaneous. We'd like to have some way that we can record short video messages of things we're doing and send them to each other. It needs to have an iPad app that is simple enough for a three-year-old to use with help and for a five-year-old to use without help; it needs to have an Android or web client, preferably one that doesn't require an Apple ID; it needs to be able to record a short video and send it to someone. As far as I can tell, iMessage requires Apple kit (there is an Android app but it sends all your messages through a server in China...) and Whatsapp works on iPhone but not iPad. What can you suggest?

Ask Slashdot: Advanced KVM Switch? 128

jez9999 writes: I have a rather advanced use-case for my home work area that I need a KVM-type device for, and I was wondering whether such a thing even existed. I want a 3-PC setup; 2 desktops (PC1 and PC2) and 1 laptop going through a dock (DOCK1). I want to connect 2 monitors (SCREEN1 and SCREEN2), 1 mouse, and 1 keyboard (INPUTS). So far it's relatively straightforward, as I could just switch everything between the 3 devices.

But here's the kicker; I'd like at least 4 modes of operation: one mode to output PC1 video to both screens (dual-screen) and redirect INPUTS to it, one mode to output PC2 video to both screens (dual-screen) and redirect INPUTS to it, one mode to output PC1 video to SCREEN1, extend DOCK1 video to SCREEN2, and redirect INPUTS to DOCK1, and one mode to output PC1 video to SCREEN1, extend DOCK1 video to SCREEN2, and redirect INPUTS to PC1.

Basically with the latter two modes I'd like to be able to switch between inputting to PC1 & DOCK1, whilst continuing to be able to monitor each by outputting each one's video to one of the 2 monitors. However, I also want to be able to go dual-screen with and control PC1 & PC2.

In terms of ports I'd like to use HDMI (or possibly DVI-D) and USB for peripherals; not VGA or PS/2.

Is there any KVM switch out there able to do this kind of thing? I guess I'm probably looking for some kind of programmable KVM which allows me to specify, for each 'mode of operation', which inputs are routed to which outputs. Failing that, is there some other way I can get the setup I want (or something close)?

Ask Slashdot: Building a Software QA Framework? 58

New submitter DarkHorseman writes: I am looking into a new position with my employer and have the opportunity to work with the development and QA team to further the creation of a Quality Assurance Framework that will be used into the long-term future. This is software that has been in continuous development, in-house, for >10 years and is used company-wide (Fortune100, ~1000 locations, >10k users, different varieties based on discipline) as a repair toolset on a large variety of computers (high variability of SW/HW configuration). Now is the time to formalize the QA process. We have developed purpose-built tools and include vendor-specific applications based on business need. This framework will ideally provide a thorough and documentable means by which a team of testers could help to thoroughly ensure proper functionality before pushing the software to all locations. The information provided by along with other sources has been invaluable in understanding the software side of QA but I have seen very little in terms of actual creation of the framework of the process. What would you consider the best resources to prepare me to succeed? Even if your QA needs are for smaller projects, what advice do you have for formalizing the process?

Ask Slashdot: Make Windows Update Install Only Security Updates Automatically? 288

An anonymous reader writes: After the news earlier this month about Microsoft forcing the Windows 10 upgrade on people who don't want it, my sizeable extended family has been coming to me for a solution. They don't want to be guinea pigs this early in the Windows 10 release cycle, but it looks like Microsoft may not be giving them a choice. My reading of Woody Leonhard's advice is that the only way to ensure the upgrade doesn't happen is to disable Windows Update, but that seems extreme. I want my family to install security updates, but I don't relish the idea of explaining to them how to install just those and hide the less-desireable updates.

The ideal solution would be to have only security updates install automatically, but it looks like it's easier said than done. I've looked at third-party tools like Autopatcher and Portable Update, but a security-only option doesn't seem to be very standard. From what I've read, Microsoft doesn't even package security updates separately, sometimes mixing merely Important and Recommended updates in the downloaded CAB file. I wish I could get them off Windows, but it's not an option. They use Windows at work or school, and don't want to go through the process of learning another OS. Maybe the current situation with Windows 10 will convince them eventually, but they need something now. I would really like to come up with a solution before the next Patch Tuesday on October 13. Do any of the more knowledgeable Slashdotters out there have any advice?

Ask Slashdot: Recommendations For a Reliable Linux Laptop? 237

An anonymous reader writes: I will be looking for a new laptop soon and I'm mostly interested in high reliability and Linux friendliness. I have been using an MSI laptop (with Windows 7) for the last five years as my main workhorse and did not have a single, even minor problem with the hardware nor the OS. It turned out to be a slam-dunk, although I didn't do any particular research before buying it, so I was just lucky. I would like to be more careful this time around, so this is a hardware question: What laptop do you recommend for high reliability with Linux? I will also appreciate any advice on what to avoid and any unfortunate horror stories; I guess we can all learn from those. Anti-recommendations are probably just as valuable, a lesson I learned when an HP laptop I bought (low-end, I admit) turned out to be notoriously fickle when it comes to Linux support. Since our anonymous submitter doesn't specify his budget, it would be good if you specify the price for any specific laptops you recommend.

Ask Slashdot: Herding Cats, Aging Systems? 158

An anonymous reader writes: I've recently started a job at a medium-sized enterprise in the UK. They claimed to be an advocate of open-source. The job was advertised as a Linux sys-admin. I've been in the role a short while and the systems right across the business are end-of-life: lots of XP and 2003 servers, a handful of LAMP web servers, and a large IT department with almost no skills in the technologies on site. Most boxes have the default password still. As a senior techie, I've been tasked with helping bring the skillset of the rest of the staff up. Where would you start, given that most of the kit is EoL?

Ask Slashdot: How Do I Recover From Doxxing? 370

An anonymous reader writes: I've been doxxed on a popular forum, by one of the moderators no less. The forum owner doesn't care, the hosting company doesn't care. I'm getting bombarded by email and social media, even via GitHub. How does a person recover from this? I don't want to create a whole new identity or shut down all my web sites, social media etc. Can't really change my real name either, at least not without an incredible amount of hassle. The police don't care, and since the forum owner is on the other side of the world it's unlikely there could be any legal consequences, and even if they were they would probably only draw more attention to me. I've tried to clean up Google's search results about me. How do I fix this? What does a fix even look like?

Ask Slashdot: What To Do About Android Malware? 191

An anonymous reader writes: What's your approach to detecting and dealing with Android malware? I have a fairly new, fairly fancy phone running Android Lollipop, the recently degraded performance of which leads me to believe that it's infected with malware. That, and a friend who noticed a lot of strange activity coming from my phone's IP — sorry, I don't have the logs, but he pointed out that there were pings coming from my phone to a lot of sketchy addresses — which pretty much seals the deal. There have been lots of stories lately about Android malware that remind me of the old saw about weather: everyone talks about it, but no one does anything about it. However, that can't be completely true, and before I reach a phone crisis, I'd like to get some sane, sage advice about diagnosing malware, and disposing of it, or at least mitigating its damage. When it comes to diagnosing, I don't know what software to trust. I've heard positive things from friends (and seen both positive reviews and terrible negative ones, raising even more meta questions about trust) about Malwarebytes, so I installed their mobile version. This dutifully scans my system, and reports no errors and malware. Which doesn't mean there isn't any, though I'd be happy to find out that I'm just being paranoid. The OS is stock (Motorola Nexus 6) and kept up to date. I have only very conventional apps, all downloaded from Google's Play store, and believe it or not I don't visit any dodgy websites on my phone, at least not intentionally. So: what's the most reliable way to get an accurate view of whether I am dealing with malware at all, and hopefully to eradicate it? Good malware hides well, I know, but is there any tool on the side of the righteous that is currently best at rooting it out? If I find a specific form of malware on my phone, how can I remove it?

Ask Slashdot: How Do You Organize Your Virtual Desktops? 125

hyphenistic writes: As a programmer I find myself switching between multiple projects on a daily basis. Virtual desktops have been a big help in grouping my related programs together. I try to have a virtual desktop open for each project I'm working on. Although I've used Linux in the past my currently preferred desktop OS is Windows 10. For the most part I have found the new virtual desktops to be easy to use. My primary issue (regardless of OS) is that I really don't want my virtual desktops to interact with each other. In the past I have accomplished this with a separate login for each project but that brings the hassle of managing multiple sets of OS and application preferences. Can someone suggest a better method for organizing my virtual desktops?

Ask Slashdot: How Would You Introduce Kids In Rural India To Computers? 218

asto21 writes: A friend of mine wants to introduce school kids in rural India to computers and could use some advice. Key questions: What learning material to use and how to source? What programming language to start with? What software to introduce them to? What games to introduce them to? Key constraints: The kids don't know much English and speak a local language called Odiya. There aren't any technical publications/resources in Odiya. Poor internet connectivity. No computer experts on the school staff. Any other advice/help would also be appreciated.
