What is the Best Multi-Monitor Calibration Tool? 55

sojourndeath asks: "I am looking for a good way to calibrate multiple monitors (30-40), so that their color looks similar? It seems like everything I find is for profiling your monitor to your printer and scanner. I need to be able to have a bunch of users see the same color on any monitor? Does anyone have a good, accurate way of doing this?"

A Savant Explains His Abilities 930

numLocked writes "Of the few hundred autistic savants in the world, none have been able to explain their incredible mental abilities. Until now, that is. It seems that Daniel Tammet, a mathematical savant who holds the record for the most digits of pi recited from memory, is able to explain exactly how he intuits answers to mathematical problems. Tammet is quite articulate and speaks seven languages, including one he invented. The Guardian is running an article about his amazing abilities."

Electronic Gadget Ideas for a New House? 413

pmadden asks: "I'll be building a house this summer (standard straw bale construction, earth plaster, the whole low-tech gig). Naturally, I'll be putting gobs of ethernet in the walls, with drops to the rooms, on the roof, and so on. I'll add wireless too, once it's secure enough to keep all of you out. What gadgets should I plan for, so that I don't have to do a major retrofit? I'll have cables for TPZ cameras, for when they get super-cheap. We'll leave niches for putting in routers and stuff like that. What else? What cool thing will be cheap in a couple of years, leading my wife to ask, 'why didn't you plan for that'? Any recommendations for good Christmas light control systems, and so on?"

Using a Cellphone in a Basement? 62

Nimsoft asks: "I recently moved into a basement flat and as a result I get no cellphone coverage in there. This is incredibly frustrating as my cell provider is so much cheaper than landline offerings I rely on my cell as my primary means of telecommunications. I can pick up a signal the second I step out of my front door and friends on other networks can sometimes pick up a weak signal within my flat. What would the geek solution (must be cheap!) to this issue be? Would attaching a larger antenna to my phone work, or can I hack together some sort of repeater and put an antenna outside somewhere?" While thousands of offers of repeaters and signal boosters are only as far away as the nearest Google search, what recommendations or experiences would you care to share on the subject?
Education

How Would You Select a Textbook? 116

benj_e asks: "I'm thinking about doing some adjunct teaching at a couple of local community colleges, and have the opportunity to choose the textbook for an online JavaScript class. In the training classes I've given in the corporate world, I didn't have the need to select a text - there were no textbooks for the software I was teaching students to use aside from the manual. I'm pretty sure I want something with WebCT or Blackboard content, but other than that I'm, well, clueless. So, for all you educators out there - how do you go about selecting a textbook? What goes into your decision making process?"

Where are the 'Modern' Directory Services? 504

MarcQuadra asks: "I've been a Linux user since 1998, and I admin Mac OS X machines at work, but I have yet to find a distribution that comes out-of-the-box with modern directory services. Sure, there are guides to kerberize and set up OpenLDAP, but before I can start pushing Linux as an alternative at work I'll need a few things. Are there any distributions out there that can auto-mount SMB shares as home directories without heavy modification? How about a distro that's based on OpenLDAP and can easily be configured with LDAP-enabled SAMBA and Kerberos? Am I missing something, or is this not a priority with the community at-large?"

Piimpin' Out Your Corporate Office? 133

ignoringReality asks: "I just moved into a new office at work that is considerably smaller than my previous one. The furniture is crappy, the walls are plain, and there aren't any windows. I'm trying to think of a unique way to keep myself entertained but not distracted day in and day out. It's a corporate office, so there are obviously limits. Working in a box must be a pretty standard situation for a lot of Slashdot readers, so how do you guys personalize your offices?"
GUI

What Makes a Good UI? 188

OSXCPA asks: "While there are plenty of OS business apps from accounting to ERP, they seem to share a common failing with "commercial" software - the user interface is terrible! Has anyone seen an application that has a UI that made you sit up and stare in amazement at the simplicity and effectiveness of it? For the techno-elite, drooly-gui may not be a priority, but I am working on a project (OS) where I have to show real savings (in task performance time and reduced data entry error) on a specialized accounting system via better UI. Am looking for some inspiration. Any ideas? Projects? Books?"

Open Source Web-Based File Management? 54

mister_bee asks: "I've been tasked with finding the best solution for implementing a web-based file management system. The goals of the system are easy management of files and permissions by the admin and a simple interface for the client. In this implementation, the client should only see their files and folders and not be bothered by file upload capabilities or permissions. Over the years I've seen a need for such an animal time and time again and have never found a project that I was happy with. There's always the possibility of modifying one of the many web FTP implementations that can be found over at Freshmeat of SF. Suggestions anyone?"

Daffodil DB / One$DB - How Do They Compare? 36

capt.mellow asks: "It's been mentioned that Daffodil Software has just released php extensions for their java-based commercial and open-source databases, Daffodil DB and One$DB respectively, enabling these databases as options for running web applications. Personally, I have never heard of these databases before. How do they compare to the likes of Oracle, SQL Server, MySQL, PostgreSQL, Firebird, SQLite, et. al.? Has anyone used them in web applications, and would they care to relate their experiences?"

Open Source Software for ASPs? 50

PsychoKodiac wonders: "I am querying the Slashdot community for help concerning ASP pages. I am currently looking for a solution to create and serve ASP content off of my own computer for the time being. I have been referred to mono_mod and SharpDevelop but I am having a difficult time finding guides or references for using these two Open Source products together. I am attracted to them due to the lack of funds needed to use them. I am hoping some one may be able to refer me to guides or perhaps an alternative to these two products if sufficient guides are not present due to the fact that mono_mod and SharpDevelop are still in development."

EULA Confusion w/ Used Copies of WoW? 935

egburr asks: "I just purchased a used retail box of World of Warcraft. After reading the EULA in the manual and the Terms of Use, I expected to be up and playing quickly. I soon ran into a problem. I haven't even installed the software yet, since the first thing I have to do is go online and create a user account and then subscribe to play. Simple enough? I thought so too, until I tried entering the Authentication Key found on the CD case. This produced an error that my key had already been used. Note that it says 'already been used,' not 'currently in use.'" Note that section 3B in the EULA explicitly grants its users the ability to transfer the physical property and "all of your rights and obligations under the License Agreement", presumably including the Authentication Key which is needed when creating a new account. What Blizzard expressly disallows is the transfer of accounts, according to Section 1E of their Terms of Use, which is not at issue here. Apparently, Blizzard is allowing each Authentication Key to be used only once, preventing anyone with a used copy of the game from creating a new account. Is Blizzard violating the terms of their own EULA?

Are nVidia's SLI Cards Worth the Investment? 98

aendeuryu asks: "So there's a lot of buzz right now about nVidia's SLI architecture, which allows for two video cards to be placed in tandem PCI-express sockets on the same motherboard to share processing. Based on the relatively low price of a PCIx 6600GT, and the promise of it dipping further, it would seem like a good idea to invest in one and an appropriate motherboard, so that one can upgrade later, right? So, for anybody who's actually got the setup at home, have SLI cards shown themselves to be worth the investment?"

VoIP for Deployed Soldiers? 362

rickbassham asks: "With VoIP really catching on these days, I decided to look into it for keeping deployed soldiers in touch with family and friends. I am currently a soldier in Iraq, and have the ability to get satellite-based internet, thanks to a few of the locals. While individually it is prohibitively expensive, a group of soldiers can come together to purchase a decent-to-high-speed internet connection. One of my plans is to link other soldiers to Vonage or another VoIP provider, so they will be able to keep in touch. Understanding the latency issues with VoIP via satellite (not to mention the other disadvantages), what upload speed does Slashdot recommend as a minimum for a QoS enabled connection for about 15-20 soldiers? The same for a non-QoS connection? What recommendations do you have for a good VoIP provider?"
