Is There Too Much Enthusiasm Over Wireless? 284

lukOh asks: "in the US, 802.11b/g (2.4Ghz) devices use an 83Mhz-wide frequency range; in-use channels spanning 22Mhz and centered on one of 11 5Mhz steps (badly named as "channels"). This means there should be no more that 3 networks in close proximity, 5 'channels' far from each other, to avoid harmful interference. Now, in the middle of the mixed area where I am, the number of usable WLANs (SNR>20dBm) has gone from 10 to an unworkable number of 20, in just one month. Has the community/the market overestimated the practicality of wireless networks? Are we generally relying too much on such a young, IMHO immature technology made on 'startups hope' and broken firmwares? How can this mess possibly be handled in a working environment, especially the moment your boss asks you to give him access to 'the wireless'?"

Building Distributable Linux Binaries? 128

Grubby Games asks: "I make games for a living, and I want to ensure that my games will run on as many Linux distros as possible. However, since I distribute binary game executables, the programs often fail to run on certain distros because of missing dependencies, and so forth. So, how do the Slashdot Linux gurus handle this situation? I've heard a number of theories on the subject, but have yet to find one that results in 100% cross-distro compatibility. Is it even possible, short of distributing source code?"

Geeky Gifts for New Dads, The Goodfather 187

The Moose at Dr.MOZ writes "The Goodfather, 'for the baby he can't refuse.' The Goodfather is a custom-boxed CD-ROM that teaches new dads hundreds of baby skills and baby related definitions through a fun parody of a famous American gangster epic (The Godfather). The baby/parenting topics in The Goodfather CD-ROM were selected for men by experienced dads and grandfathers, and edited by licensed nurse-midwives to ensure the material is medically sound. In addition to the hundreds of baby skills lessons and definitions, The Goodfather also has a Baby Name Book with approximately 15,000 baby names and a Baby Card Maker which allows new dads to make and print their own baby cards. New dads choose from dozens of "new dad" card-types with provided art, or they are able to import JPGs to create their own customized baby cards! The Goodfather runs on both Windows® and Macintosh® systems and is proving to be the next 'must have' gift for the sometimes ignored new dad on the baby shower list."
GUI

Balancing Use Between the Keyboard and Mouse? 121

initialE wonders: "A friend of mine, working for a bank, mentioned to me that she had just undergone training for the migration of applications from their legacy systems (think DOS-based interface, AS400 powered) to a snazzy new web application. Whereas the younger users were impressed by the bling it provided, the older users were less happy, and the reason provided was that the application lacked shortcut keys to doing their most common tasks. The newer staff were mighty pleased not to have to learn all those arcane commands, of course. This led me to consider a few things. I administer Windows-based systems, and more and more I am choosing to use whatever key-based interface is available - I don't even use the file explorer anymore, preferring to type 'WindowsKey+R', and typing in the file path (Windows helps with auto-complete). It's better for me to keep my hands on the keyboard and not touch the mouse. It's certainly not because my mouse is bad, I just don't want to release the focus on the keyboard. And it works - I get things done a lot faster than anyone else in my department. Have we placed too much emphasis on making GUI-based applications, and left behind what was a perfectly good way of doing things?"

Email On Both the Desktop and the Laptop? 69

RapterOfParadox asks: "I recently purchased a new laptop and have everything configured except for my e-mail. I've always liked having a single location where I know my e-mail is safe, secure and gets backed up automatically. If I've needed access to new messages then I use webmail, since I close down the email client when I leave the house. I'm currently using Outlook XP for my desktop and was thinking about using the same for my laptop. My only issue is that I'm a little weary about using only my laptop for storing e-mail, since it's a lot more likely to fail. I've been thinking about just synchronizing my Outlook data directories at login, or even using IMAP. Has anyone seen/bought/built an e-mail client that will allow me to have my main e-mail client on my desktop and then update my laptop e-mail client when ever I'm in range, or through a personal IMAP Server?"
Education

Recruiting IT Students? 631

spacemonk asks: "I teach at a community college and our enrollment numbers are down in our IT programs. We have found that many have the perception that there are few IT jobs. We feel this is causing many students, who might be interested in IT, to enroll in other programs. There is obviously a lot of conflicting information regarding the impact of off-shoring, and so forth, but much of what we have found indicates that the IT job market is improving, and IT is still a career that can offer job opportunities to students. For example, we have had internship opportunities that we have not been able to send candidates to, simply because we don't have the students. Needless to say, this is very frustrating. How would you honestly describe the IT job market to students considering this major? What can be done to recruit more students into IT programs?"

Building PCs - How do you Choose Your Components? 106

ATP asks: "It's been a few years since I built my current system by ordering parts from the cheapest vendors I could find. Everything went smoothly with very little research, and my system is still running great today. I'm now looking into building another desktop system, but I've become quickly overwhelmed by how complex components have become. In particular, motherboard/CPU compatibility are confusing (think: single/dual, socket 478/604/754/939/939pciExpress/940/LGA775, OS compatibility, memory types, etc). Is there a guide to the not-so-novice PC guru somewhere that would help me catch up on the developments in the last couple years?"
Biotech

Organizing Organic Chemical Reactions? 77

thethinkingilia asks: "I am studying organic chemistry and I am seeking an intelligent way to organize all the reactions that I am responsible for memorizing. In general, one can think of this as a directed state machine where a functional group can be transformed to another functional group given set conditions. It must be robust enough to allow for tens of states, the possibility of connection between any of said states, and be able to display not only the states, but conditions for transition between these states. This could be accomplished with HTML hyperlinks, but it would be great to have an elegant flow chart-type solution. Please, help me bring some software sanity to the life sciences!"

Wireless/Wired Router Solutions for 2 Networks? 73

DaveTheBrave asks: "I'm currently running a home based business on an el cheapo Netgear wireless router off a broadband cable modem connection. I'm looking to upgrade to something better with more flexibility. My in-laws recently sold their home and will be moving into my home temporarily while they are building another. They have a home based business and my mother-in-law is also notorious for attracting viruses, adware and other nasty stuff on her PC (which I have to routinely clean - hence my need for a better network solution). What is the best/easiest solution to segment and keep separate my network from theirs (both wired and wireless) off of one incoming cable modem? I'm looking for something around or less than $500."

Finding a Ready-Made Dev Team? 294

marshrew writes "We are a small startup just coming out of a period of R&D with IP and prototype code (containing open source, commercial & freelancer-built custom components) developed/integrated in-house by essentially one guy. We're at the point where we want to build out first commercial implementation which will require a handful of developers for at least six months. We really don't have time or funds to go through a developer recruiting cycle, create a practice, get the team "gelled" etc. What we'd really like to do is find a small pre-existing team which which we could form a relationship to get our product out the door and possibly continue working with. We don't mean a splinter group from a larger dev house, but an agile, self-contained team, who enjoy working together and have an existing practice. Geography is not a problem as we are used to working in a distributed manner." Does such an animal exist? What have other teams done in a situation like this?
Software

Batch Cataloging of Scanned Documents via OCR? 31

munwin99 asks: "I am looking for some software to process a batch of images (scanned forms). We want to use Gallery to view the images, and be able to search them by 3 or 4 attributes. We want to get these attributes from the form (date, name, etc). We want it to check a section of the scanned form, read the info from that section(s), and dump the retrieved info into Gallery (using OCR / ICR). Is there any (preferably) free or open source software that can do this? Supported OSes should include either Windows, Linux or Mac OS X. Even Gallery is optional, if someone has a better suggestion."

Maintaining Windows XP System Performance? 159

jerud wonders: "I assume that most people on Slashdot are forced to, at some point, touch Windows. Further, I assume that many of them are forced to administer Windows boxes. I am in the unfortunate situation of using Windows for about 90% of my tasks, due to the nature of my job. As a firm believer in 'if it isn't broke don't fix it', I've delayed moving to XP for just about as long as possible, holding onto my Windows 2000 installation, while my brother spent a lot of time complaining about the XP issues he dealt with, at work. Finally, I made the transition and, low and behold, it didn't seem to bad. In fact, there were a few things that I really liked. Now, a few years later I have quite a few XP machines and they all share the same problem: over time they have slowed so noticeably that they have made even the most solid configurations run like they were made in 1999. Is there any regular treatment out there that can minimize this kind of system degradation?"

HDTV Archiving on a Mac for Playback on TV? 23

josefresco asks: "I have one goal for HD streaming: archiving. As we all know, the Comcast DVR box doesn't have a whole lot of HD. What can you expect with only a 120 GB hard drive? The thing really should have a 500 gigger or at least a 250. So right now, when the box gets full, in order to avoid the box automatically erasing unwatched shows, I dump the transport streams to my Mac via Firewire. I don't necessarily need to watch the shows on the Mac. At that point, I just want a solution to allow playback of the transport streams from the Mac back to the TV. Enter the Xbox 360. Might this be the answer to my problems? If not, then are there other devices that might be?"
GUI

What Tools Do You Use for UI Prototyping? 88

AccUser asks: "There are many articles discussing methods of UI prototyping. Having been involved in the design and implementation of a number of commercial applications (both desktop and embedded), I know the value of producing early prototypes of the UI. In the past I have used visual programming tools, such as Visual Basic, but there is always that request: 'Can't you just complete the prototype and release it?' One project I was involved with, the UI prototype employed hand drawn graphics (including hand written text labels, etc) in order to be explicit about the fact that it was a prototype. What I would like to know is what tools and techniques do you use for UI prototyping, and how do you manage your client's expectations?"
