Ask Slashdot: How Do You Handle SPF For Spam Filtering? 187

Posted by samzenpus
from the false-positive dept.
An anonymous reader writes "Our organization had had a decent SPF record of our own for a long time. Recently, we decided to try using SPF for filtering inbound mail. On the up side, a lot of bad mail was being caught. On the down side, it seems like there is always a 'very important' message being caught in the filter because the sender has failed to consider all mail sources in writing their record. At first, I tried to assist sending parties with correcting their records out of hope that it was isolated. This quickly started to consume far too much time. I'm learning that many have set up inaccurate but syntactically valid SPF records and forgotten about them, which is probably the worst outcome for SPF as a standard. Are you using SPF? How are you handling false positives caused by inaccurate SPF records?"

Ask Slashdot: Open-Source Forensic Surveillance Analysis Software? 131

Posted by Soulskill
from the my-neighbor's-dog-is-a-jerk-too dept.
McBooCZech writes "I am trying to set up a surveillance system. It is not intended to build a real-time on-line surveillance system to watch a wall of monitors on a 24/7 basis. The main scope is to record video (24/7) from the fixed cameras around our facility and when needed, get back to pre-recorded video and check it for particular event(s). Of course, it is possible to use a human to fast forward through video using a DVR-type FF function for short video sequences. Unfortunately, for long sequences (one week), it is not acceptable solution. I was searching online the whole weekend for the open source software for analysis of pre-recorded video in order to retrieve events and data from recorded video but had no luck. So I ask you, Slashdotters: Can you provide some suggestions for forensic software to analyze/find specific events in pre-recorded video? Some examples of events: 'human entering restricted zone,' 'movement in the restricted zone,' 'light in the restricted zone.'"

Ask Slashdot: Programming / IT Jobs For Older, Retrained Workers? 215

Posted by timothy
from the over-22-not-interested-next dept.
12_West writes "I seek opinions from the Slashdot community about entry level job opportunities as programmers (or other I.T. Staff) for seniors who want to switch careers and continue to work full time. I do not want to retire, nor go part time, as long as I can get up and drive myself in to work. I'm currently 58 years old, working as an industrial electrician in a maintenance department setting for a building products manufacturer. I like the work, but it is becoming hard on my aging body, so, I would like to begin gradually retraining and hope to switch careers in about four years. A lower paying, less physical job would be just fine as there will be pension money coming in. I'm not currently a programmer, but have done some hobbyist level coding in Qbasic and MS-DOS batch files 'back in the days.' I also have some exposure to the Rockwell Automation RSLogix programming tools that are now going obsolete. So, I will be retraining whether I switch careers or not."

Piriform Asks BleachBit To Remove Winapp2.ini Importer 305

ahziem writes "As author of the BleachBit system cleaner, I received a polite but firm request from Piriform, makers of the similar application CCleaner, to remove a two-year-old feature from BleachBit that allows individual BleachBit users to import winapp2.ini data files created by the community that define which files to delete for applications. Does Piriform's request have merit? Do I need a lawyer? What is a good response to avoid any ugly situation?"

Ask Slashdot: What To Do About Patent Trolls Seeking Wi-fi License Fees? 347

Posted by samzenpus
from the send-us-your-money dept.
An anonymous reader writes "My company has been contacted by certified letter by Delaware law firm. They are seeking license fees for a Wi-fi patent. I believe this is a patent troll (not that this matters in relation to dealing with this issue). This is a newly formed law firm less than 4 months old. This patent is U.S. Patent No. 5,506,866. This patent covers equipment and method related to the transmission of information involving the multiplexing information into a stream of signal points (and demultiplexing the same), and related technology. They have 'offered' to license this patent with no amounts specified. Unfortunately we are a small free software company. The company is setup as a sole proprietorship. I'm not asking for legal advise from the Slashdot community. The question is where might one look for 'legal counsel' with the expertise to answer these types of legal questions as it relates to this inquiry. I would prefer to avoid legal fees, court cases, or license fees running the company into the ground. The company is registered in New Jersey."

Ask Slashdot: How Long Do We Give an Online Service To Fix Issues? 113

ncc189 writes "The Funimation Roku channel has been basically unusable during primetime for about a month now. With very little feedback from the company and no improvements to the service at all, I canceled my account. My question to Slashdot users is: how long do you give a service to fix issues before you cancel the service, and how much leeway do you give the service's representatives in communicating issue with us? It seems to me that a few days is more than enough in the internet age; 3+ weeks is beyond reason. How long do you think is fair for services like this?"

Ask Slashdot: Name Conflicts In Automatically Generated Email Addresses? 383

Posted by timothy
from the hash-of-full-name-plus-birthday dept.
New submitter matteocorti writes "I work at medium-sized university and we are considering reducing the number of domains used for email addresses (now around 350): the goal is to have all the 30K personal addresses in a single domain. This will increase the clashes for the local part of the address for people with the same first and last name (1.6%). We are considering several options: one of them is to use 'username@domain.tld' and the other is to use 'first.last@domain.tld.' The first case will avoid any conflict in the addresses (usernames are unique) but the second is fancier. Which approach does your organization use? How are name conflicts (homonyms) solved? Manually or automatically (e.g., by adding a number)?"

Ask Slashdot: Open Source Remote Application Access? 113

Posted by timothy
from the over-there-but-over-here dept.
First time accepted submitter taikedz writes "Citrix Xenapp with Receiver/Metaframe allows publishing individual applications installed on a Windows server to users on remote machines. These applications open in their own windows, along side others as if they were installed locally. I am looking to do the same at home, with free software, publishing applications from Mac, Linux, and Windows machines (and yes, I've verified the license agreements for the apps I am going to do this with!). Up until now, the only alternatives I have found are full-on remote desktop login, not seamlessly-integrated. Can you recommend any tools that can achieve the goal of remote individual application access across platforms for free or at low-cost?"

Ask Slashdot: Best Electronics Prototyping Platform? 228

from the arduino-attack-bot dept.
crankyspice writes "Having recently picked up the Erector set I've wanted since I was a kid, I quickly found myself wanting to plunge deeper into makerspace by adding more sophisticated electronics to moving devices (rovers, maybe eventually flying bots). My first instinct was Arduino (maybe because of brand recognition?), but that got me thinking — what's the 'best' platform out there (most flexible)? Arduino with its myriad options (Nano, Mega, Uno, Mini)? PICAXE? BASIC Stamp? Raspberry Pi? (The latter seems like it would easily be the most flexible, but at greater cost in terms of weight and complexity.) I'm a hobbyist programmer, having learned C and C++ in college and recently re-learning Java (took and passed the Oracle Certified Professional exam, FWIW)..."

sconeu writes "My wife uses an assistive communication device. She wants to use it for SMS texting... We currently have Verizon, so we don't have a SIM. The computer will take a SIM. I'm looking for a pay-as-you-go plan where I can take the SIM from a cheap phone and put it in her computer. Any suggestions?" It would be interesting to hear how this question would be best answered both in the U.S. and around the world.

Ask Slashdot: Where Are the E-Ink Dashboards? 242

fsck! writes "My office recently installed a pair of huge plasma TVs to display some metrics and graphs. They only update every 15 minutes or so, and I couldn't help but wonder, why can't this be E-Ink? I searched all over the place but couldn't find anything bigger than 9.5" (Amazon's Kindle DX). I want a >30" E-Ink picture frame with USB or WiFi. Can the Slashdot community find anything greener than these energy sucking plasma TVs that seem to be everywhere?"

Ask Slashdot: Job Search Or More Education? 182

Posted by Soulskill
from the can't-it-be-both dept.
Matt Steelblade writes "I've been in love with computers since my early teens. I took out books from the library and just started messing around until I had learned QBasic, then Visual Basic 5, and how to take apart a computer. Fast forward 10 years. I'm a very recent college graduate with a BA in philosophy (because of seminary, which I recently left). I want to get into IT work, but am not sure where to start. I have about four years experience working at a grade/high school (about 350 computers) in which I did a lot of desktop maintenance and some work on their AD and website. At college (Loyola University Chicago) I tried to get my hands on whatever computer courses I could. I ended up taking a python course, a C# course, and data structures (with python). I received either perfect scores or higher in these courses. I feel comfortable in what I know about computers, and know all too well what I don't. I think my greatest strength is in troubleshooting. With that being said, do I need more schooling? If so, should I try for an associate degree (I have easy access to a Gateway technical college) or should I go for an undergraduate degree (I think my best bet there would be UW-Madison)? If not, should I try to get certified with CompTIA, or someone else? Or, would the best bet be to try to find a job or an internship?"

Ask Slashdot: How To Convince a Team To Write Good Code? 366

Posted by Soulskill
from the cattleprods-are-your-best-bet dept.
An anonymous reader writes "I am part of engineering team that maintains a very important component in our company. Our code quality and general engineering quality focus has been very weak: we have frequent buggy releases, our latencies are shooting up, our test coverage is nearly non-existent, and it is impossible for a newcomer in our team to get up to speed and be productive in less than a month due to unnecessary complexity. A group of 2-3 of us want to change that, and we know what needs to change technically — the better code review and release processes, better build tools, etc. But despite that, the quality of our code and design continues to suffer, and poor code continues to get released in the name of keeping the scheduled release date (product guys don't like to wait). We feel that if the right thing is done every time, we would can eliminate our issues and still release at the same pace. How do we effect the social change necessary to convince them of what is better and encourage them to take the effort to do it?"

Ask Slashdot: Best Webcam To Augment Impaired Vision? 63

from the tickle-me-elmo-via-usb dept.
mynamestolen writes "In order to read paper-based books many visually impaired people want to attach a webcam to a computer and attach the computer to a TV. Some Electronic Magnifiers are purpose-built to provide a similar solution. Different organisations around the world (such as in the UK) have help pages. But I have not been able to find a guide to set up my own system. So I'm asking Slashdot readers how to go about it. What is the best camera to use if I want to hold the camera in my hand and point it at book or magazine? What parameters should I adjust, either in the software or on the camera? Depth of view, refresh rates, contrast, color balance and resolution might be key problems. My system is Linux and getting drivers for a good camera might also be a problem."

Ask Slashdot: How Do I Get My Spouse To Start Gaming With Me? 550

Posted by samzenpus
from the time-to-play dept.
x_IamSpartacus_x writes "I've been a gamer for a long time (started on Nibbles in MS-DOS) and enjoy pretty much any good game. I can enjoy side-scrolling relics (original Prince of Persia, Win 95), to modern MMORPGs (stopped playing my 85 lvl Mage on WoW just recently, read on to see why), to a good sports game (Madden series are a blast) and many more. I've been married for 4 years now and have hardly touched my games since being married and starting having kids. My wife and I are Americans but live overseas and have little access to new movies/entertainment and, from experience, I know that a good game can provide much more entertainment than a good movie. My question is, what are good ways/good games that I can use to get my wife into computer gaming? We both have good laptops that I'd love to get her interested in using to do co-op or combative games with me. Because of my long experience, gaming comes naturally to me and so even on a game I haven't played I would probably be much better than she. Is there a game or idea that would take away the embarrassing factor for her of being much worse than I am while still being enjoyable and worth spending a lot of time on with me? Do any other Slashdotters struggle getting their spouse to game with them?"
