Best Seating Arrangement For a Team of Developers? 520

TekNullOG writes "I was given the job to prepare the logistics involved with moving our office. At the same time my bosses asked me to look into buying new desks for a small team of four developers and to consider if it could benefit the team to sit at a round table. In many offices and departments it increases productivity and makes collaboration easy. However, I am concerned that putting developers around a table could potentially be distracting consequently diminishing productivity by increasing coding errors. What are your thoughts?"

Software SSD Cache Implementation For Linux? 297

Annirak writes "With the bottom dropping out of the magnetic disk market and SSD prices still over $3/GB, I want to know if there is a way to to get the best of both worlds. Ideally, a caching algorithm would store frequently used sectors, or sectors used during boot or application launches (hot sectors), to the SSD. Adaptec has a firmware implementation of this concept, called MaxIQ, but this is only for use on their RAID controllers and only works with their special, even more expensive, SSD. Silverstone recently released a device which does this for a single disk, but it is limited: it caches the first part of the magnetic disk, up to the size of the SSD, rather than caching frequently used sectors. The FS-Cache implementation in recent Linux kernels seems to be primarily intended for use in NFS and AFS, without much provision for speeding up local filesystems. Is there a way to use an SSD to act as a hot sector cache for a magnetic disk under Linux?"

GUI-Based Asset-Tracking Tools For a Datacenter? 113

toruonu writes "How do you keep track of what's in your datacenter, where it is, what it's connected to and what is it doing right now? I mean I have built a datacenter from scratch over the years and I have machines from Sun, IBM, HP, Supermicro. I have machines that are simple workernodes and machines that are heavy grade storage consolidation machines. Then there are tens of switches, some for interconnect, some for management and don't get me started on the UPSs etc. So how does one keep any kind of decent track of such a system as the current form of twiki pages with various tables just doesn't cut it anymore and I'm looking for a freeware solution that could actually show me a visual representation of the various nodes in the racks, their connections and dependencies. Just to give a simple example, if I'm going to disconnect UPS #3 right now and swap switch #5, which machines should I even consider taking offline?" (The best-looking such system I've seen was being used at OSCON at a display booth for the Open Source Lab, and I think it was home-grown. Anyone who can shed light on that system?)
Software

Simple CMS For Mixed Mac/Windows Team? 119

Quasar Sera writes "I am looking for a content and/or project management solution for a marketing research team using both Macs and PCs. Ideally it would support document sharing, metadata/tags, search capabilities, revision control, and the ability to share documents easily with people from outside the team without any software installation or login required. It may be tricky to configure (since I will be doing that) but must be dead simple to use for the rest of the team. We rely mostly on Word, Powerpoint, and Excel (all in their native file formats) for our work, so it would be a large number of fairly small files. Any and all advice would be appreciated."
Linux

Good, Portable "Virtual" Linux Distro? 261

Prof. Nix writes "I have been given the opportunity to redesign the Linux course for the community college I work for. This course will be taking students from the 'What's Lee-nux?' stage to (hopefully) Linux+ Certifiable in about three to four months. However, one issue I haven't solved is finding a semi-stable, highly portable, and readily accessible platform the students may pound on, and have root access, independently of their peers. The powers-that-be have already vetoed any sort of server environment accessible from off campus. We've already tried live USB drives, but we ran into many issues with non-supported hardware on students' home computers. So I'm left with the idea of virtual machines run from flash drives. My ultimate goal is to have some sort of portable system that students can use with equal ease on lab systems and personal laptops — regardless of hardware. Preferably this system would be installable on a 4GB flash drive and run an Ubuntu- or Fedora-derived OS. So I ask the people who have been in the trenches a lot longer than I — what distros should I look at?"

What Is the Future of Firewalls? 414

jlmale0 writes "When I mess with my WAP/router at home or coordinate with the network team at work, it seems like I'm stuck in 1995. We're still manually listing IP address/port combinations for our firewall rules. There's a certain simplicity to this when dealing with a single system, but there are firewalls everywhere these days. What's available for managing complex firewall arrangements? What's being developed? Can I take a Visio diagram, run it through a script, and get a list of firewall rules? What about a GUI that illustrates the current system configuration and then lets me drag and drop systems across firewalls, and have the individual firewall ports automatically configured? What about tying a firewall into an authentication system so that when jdoe logs in, only then are the firewalls opened to pass her traffic? What about managing distributed firewalls so that one repository of rules opens up your system's firewalls, the DMZ firewall, and the public firewall all at once? Let's get a conversation started. What cool projects do I need to know about? What cool management features would you like to see? What's next for firewall management?"
Ubuntu

Virtualizing Workstations For Common Hardware? 349

An anonymous reader writes "We have approximately 20 workstations which all have different hardware specs. Every workstation has two monitors and generally runs either Ubuntu or Windows. I had started using Clonezilla to copy the installs so we could deploy new workstations quickly and easily, when we have hardware failures or the like, but am struggling with Windows requiring new drivers to be installed for all new hardware. Obviously we could be booting into Ubuntu and then load a Windows virtual machine after that, but I'd prefer not to have the added load of a full GUI underneath Windows — we want maximum performance possible. And I don't think the multi-monitor support would work. Is it possible to have a very basic virtual machine beneath to provide hardware consistency whilst still allowing multi-monitor support? Does anyone have any experience with a technique like this?"
Businesses

Studying For Certification Exams On Company Time? 281

An anonymous reader writes "Companies sometimes require employees to hold or obtain certifications — for example in order to achieve Cisco certified partner status. Some companies pay for employees' exams and encourage employees to study on company time. Others expect employees to obtain mandated certifications on their personal time and dime. Should companies be able to require employees to obtain a certification, but refuse to pay for it, under threat of losing their job to a certified individual? Should it be or is it even legal to demand this of employees, especially if such a certification was not required at the time of hire?"

How Do I Fight Russian Site Cloners? 208

An anonymous reader writes "I used to run a small web design service, the domain for which I allowed to expire after years of non-use. A few weeks ago, I noticed that my old site was back online at the old domain. The site-cloners are now using my old email addresses to gain access to old third-party web services accounts (invoicing tools, etc.) and are fraudulently billing my clients for years of services. I've contacted the Russian site host, PayPal, and the invoicing service. What more can I do? Can I fight back?"
Security

What Can Be Done About Security of Debit Cards? 511

JumpDrive writes "I have been the victim of (Visa) debit card theft. I do not know where they stole or got the number, but it was used one day on the other side of the country and the next day it was used in Europe until they cleaned out my account. I had been monitoring my account online and immediately went to the bank and filed a claim. I was told at that time it would be 3 to 5 weeks for them to investigate the claim before they could return my money. Recently I tried to make a purchase with a debit card and was told that they couldn't use the card since it wasn't a Visa or MasterCard check card; this led to a discussion of why I no longer have a Visa or MasterCard check card. Which then led to the question of 'What can be done about it?' Currently I have a separate account for debit usage for my personal safety. But I also think that those producing these check cards should be required to advertise the hazards of having one of these cards (not in small print and maybe required in advertisement of these cards, similar to what is required with pharmaceutical drugs on television) and/or that if a debit or check card is issued a separate account should be required for its use, and users informed of the issues of placing all of their money in the same account that their debit card has access to. What other precautionary measures should be required or taken?"
Programming

How Many Hours a Week Can You Program? 547

An anonymous reader writes "How many hours a week should a full-time programmer program? Trying to program anywhere near 40 wears me out. On a good week, I can do 20. Often, it is around 10 or 15. I'm talking about your programming session at the console, typing — including, of course, stopping and thinking for a minute, but not meetings, reading programming books, notes, specifications, etc., which by comparison feel like lunch breaks. I rarely get called to meetings (which is good) but that means to keep my brain from overheating I spend several hours a week surfing the web (usually reading tech news but also a few stops on Facebook, email, etc.). I should add that I am interrupted a few times per day. Me and another guy maintain an intranet site of a couple dozen web apps for an IT department, so we work on a few different things: phone calls, bug fixes, feature adds, as well as writing new web apps from the ground up, all in a day's work. And I know that wears a person out more than if they had just one project to work on. I wonder if programming is like mental sprinting, not walking, so you can only do it in bursts. Am I normal or stealing?"
Hardware Hacking

Where To Start In DIY Electronics? 301

pyrosine writes "I've been thinking about this for a while and have no idea where to start. I have little or no previous experience in electronics — just what is covered in GCSE physics (wiring a plug and resistors — not much, I know). The majority of my interest lies in the wireless communication side of the field — i.e. ham radios and CB — but I am also interested in how many things work, one example being speakers, simply to better understand it. I would preferably like to start with some form of practical guide rather than learning the theory first, but where I would find such a walkthrough eludes me."

What Advice For a Single Parent As Server Admin? 618

Dragon_Eater, with "lots of experience setting up PCs and a passable knowledge of Linux but severely lacking in the server/client department," writes with a situation that probably faces a lot of parents: I want to set up three kids, 12, 14, and 15, with newer computers so they will stop fighting for time on the one ten-year-old Dell they share now. I can get the individual computers and a server put together without any problems, but the computer-handicapped single parent needs to be able to do the following via an simple application/web page: View client computer status, On/off, sleeping etc.; Deny Internet access, not LAN, just the web; Schedule time usage of computer, ex. 7 am to 10 pm on school nights etc.; Force log-out and/or shutdown of clients, for grounding purposes; and Apply some kind of firewall filter for blocking undesired web content. And as the administrator for this network I would like the following options: Remote virus scanning of client machines, or scheduled task; Some kind of hardware monitor, high temp / fan speed low etc.; and Email alerts for various log files / alarms. Given the lists above I am thinking about a Linux-based router/server machine and running Windows on the clients for game compatibility. I also know that a server and network boot client is possible but not sure where to start on that one."
Classic Games (Games)

How Do I Create a Spiritual Game Successor? 125

An anonymous reader writes "I've recently been on a legacy video game binge, reliving the nostalgic days, when I realized that one of my favorite old games can be vastly improved with a few tweaks. This game is pretty much made for a controller, so I would love to get it done on Xbox Live, but doing it on the PC is just as viable. Unfortunately, I am pretty sure the game is not in the public domain yet. Based on previous stories covered here, some companies are all for community made successors while others choose to give them the crushing blow from the start. My question is: how far is too far when one is trying to make a spiritual successor? I do not intend to copy any materials, but it would be lovely if I could incorporate some game design ideas (very general level design, movement, and just one or two game features)."

ISO 9001-Compliant Document Control? 152

SmoothBreaker writes "Coming into a new company, I have been tasked with sourcing Document Control software to meet ISO 9001 standards. From everything I can find, ISO places no requirements on the software itself, aside from maintaining control of documentation and process. This was discussed eleven years ago. I'd like software that allows intuitive use for our less savvy users, and in a perfect world, graphical access to previous revisions of a document. I've used Microsoft's SharePoint, which the higher-ups like simply because it's Microsoft, but thankfully they trust their Tech Department to find the cream of the crop. What experience do you have with this kind of software, what would you recommend using, and what should I avoid?"
Encryption

How Did Wikileaks Do It? 973

grassy_knoll writes "Related to the Wikileaks video recently released and discussed here, the NY Times reports: 'Somehow — it will not say how — WikiLeaks found the necessary computer time to decrypt a graphic video, released Monday, of a United States Army assault in Baghdad in 2007 that left 12 people dead, including two employees of the news agency Reuters. The video has been viewed more than two million times on YouTube, and has been replayed hundreds of times in television news reports.' The article is light on details; what encryption algorithm was used? Was this a brute force attack? Did someone pass the decryption keys to Wikileaks along with the video? Something else?"

Tsunami Warning From Space? 351

Peter bayley writes "Tell me I'm crazy or tell me someone has already done it — but wouldn't a satellite equipped with a laser be a great way to warn people of tsunamis? I was pondering how to warn people in remote coastal areas once evidence of a seismic incident has been received by the monitoring stations that have now been set up following the large Boxing Day tsunami. The idea is to illuminate the areas that are likely to be at risk with a bright (but not dangerous) light. People would be told to head to higher ground if such a light appears in the sky. Put the satellite in a geosynchronous orbit. Make it tunable so that different colors can convey different meanings. You would be able to warn anyone, anywhere they can see the sky. The laser could be directed to illuminate only those areas at risk, skipping unnecessary areas to save power. Power could be varied so that it is visible day and night and through cloud (raise the power where the satellite detects cloud cover). I emailed some people at NOAA about it but they said it would stand on too many toes by circumventing local emergency service organizations in the various countries. I replied that countries could easily opt out, in which case the laser would be turned off for those countries — but received no further reply. Anyway, I thought the massed minds of Slashdot would relish the chance to demolish my idea."

Help Me Get My Math Back? 467

nwm writes "I am trying to refresh my math skills back to the point that I can take college-level statistics and calculus courses. I took everything through AP calculus in high school, had my butt kicked by college calculus, and dropped out shortly thereafter. Twenty+ years later, I need to take a few math courses to wrap up a degree. I've dug around some and found a few sites with useful information, but I'm hoping the Slashdot crowd can offer some good resources — sites, books, programs, online tutors, etc. I really don't want to have to take a series of algebra-geometry-trig 'pre-college' level courses (each at full cost and each a semester long) just to warm my brain up; I'd much rather find some resources, review, cram, and take the placement test with some confidence. Any suggestions?"

Rugged Laptop/Tablet Suggestions, 2010 Version? 249

robbievienna writes "I'm currently living in the Arabian desert. Typically, unless a building has been sealed against the elements, sand and dust get everywhere. I purchased a keyboard cover for one of my laptops, and noticed that there was more accumulation on the underside than the topside. I've had sand crunk up the guts of one laptop and one tablet (Nokia N810). My coworkers who are native to the region tend to trade out their technology every six to twelve months, but I don't want to migrate data and adjust to new hardware that frequently. I was wondering what suggestions people have for working in this type of environment — both for laptops and for tablets. For reference, I work in a pseudo-secured zone where computers (phones, etc.) are not permitted to have cameras. A DVD drive would be nice, but is unnecessary. The more USB ports, the better. The last time the question was posted on Slashdot was five years ago, so I'm presuming that there are new industry leaders."
Television

What's the Best Way To Get Web Content To My TV? 304

An anonymous reader writes "It seems like there are a lot of options for getting web content onto our TVs, but which one is the best way to go? Being able to stream videos (especially through sites like Hulu), check out social networking sites, and read news would be awesome to do from my couch. Currently, I hook up my laptop to the TV, which works, but it's annoying, especially if I want to use my laptop while I am watching some videos. Some things that are important to me are: connecting to my HDTV, allowing me view anything I could in a web browser as if I were on my computer, and being easily controlled from the couch. What setups do you guys use, or what would you like to use?"
