Satan's Librarian asks: "I develop software in the music industry. Most of the software is very graphical, with lots of knobs, buttons, and various other custom controls. Recently I realized one of my interfaces would be difficult for someone who was colorblind - fortunately before it shipped. How do other developers avoid this? Is there software available on XFree86, Mac OS X, or Windows that can let you run in a modified-color mode to emulate the various kinds of colorblindness? I've found one site with some cool demos of how colors are perceived with the various types of color blindness, and a lot of self-help sites and software to help people who are colorblind, but no software to help developers and graphics artists avoid causing people difficulties in the first place yet - although from the demos and articles, I expect the algorithms would be trivial. Seems to me that if the statistics I keep seeing for colorblindness are correct (~8% of males, ~2% of females), this could be an often ignored problem that excludes a lot of people from some software. If you're colorblind, how do you deal with websites and software that was poorly designed for you? Is it a problem often?"

Swannie asks: "I'm an IT consultant who is on the road a lot. Unfortunately, it's the nature of security in today's enterprise that I rarely have a client that will let me access the internet, and usually not even attach my laptop to their network. Obviously, this leads to a problem in accessing my email... a big problem. Typically, the client will provide dial up lines, but all to often those go through their PBX, which typically limits me to 21.6-28.8k... ugh. Recently, I've been researching cellular data cards, and various services. This seems like the best solution for my problem. I'm looking for something that's reasonably fast, has an 'all-you-can-eat' plan, and inexpensive. Unfortunately, I'm going to probably have to pay for it myself. Since the client does provide a way to access the internet (dialup), it gets seen as a convenience, so cost is a factor. What experience have you had with services from companies like Verizon, AT&T, T-Mobile, NexTel, and Cingular? Are there any other services that I haven't thought off (unfortunately google searches for 'wireless internet' or 'wireless data' just turns up a whole lot of crap)? Any other advice?"

pauly asks: "We are a small (5 man) specialized software company which is merging with a larger (200+ employee) company. Basically they are buying us to add a whole new product line and have us be their development skunkworks. What recommendations would Slashdot readers have before, during, or shortly after the acquisition? This post is not a solicitation of legal advice: we have a very nice contract drawn up which is agreeable to both parties and which we will be signing shortly. We are looking for practical precautions or recommendations. If you have gone through the same type of deal, what would you do the same, or differently?"

amrust asks: "I live in an area that currently is not being served by broadband in any way. Local ISP's are discussing bringing Wireless Internet into our area, and for some of the more difficult to reach places, they have mentioned 900Mhz being used. I was wondering how reliable/secure the 900Mhz spectrum is for Wireless Internet, and if anybody has some comments on experiences with 900Mhz wireless internet that they can pass on?"

swmagazine asks: "The house my family is building just burn down 2 weeks before competition. Now that the insurance is paying out some money, I am seriously considering installing Halon system at home because the house comes with a server room and I will be having at least 10 computers running in the house. I would like to know if anyone has experience with Halon system as well as the feasibility of installing such system at home." The possibility that your computer could conceivably be a fire hazard is extremely low on newer machines. Older machines, without the proper protection, may overheat, and that might cause problems. Might such a system minimize the damage posed by a house-fire, or are they too expensive (or too ineffective) for the average home owner?

wpc4 asks: "I've been working at my current place of employment in California for going on 2.5 years. I work for a rather big HMO providing IT support for over 2000 users. In my time there I have had no negative feedback, I am the "go to" for the department, I have improved our service area's image to other IT departments in our organization, had one promotion, and so forth. I am currently making over $5k less than the minimum for my title, while some new employees just got hired with the same title and lesser skills as myself and were hired on at over 30% more than I make, yet I have 2.5 years of seniority. Since I'm not union I don't appear to have any way of trying to get myself compensated appropriately, is there anything in the California labor laws that I can pull into play? Any suggestions at all before I look for other employment?"

piecewise asks: "Everyone seems to be using a Webblog these days and I'm interested in getting my company into it in a big way. We have three web servers and use Akamai to keep the website cached and happy. How many Slashdot readers are webloggers? Have you used MovableType, on a large scale? Are there any security issues? Security's very important. Is there a solution to the 'cache problem'? In other words, as people input messages, might the data running across the net become out-of-sync? Thanks for any thoughts/experiences."

zachrahan asks: "I have almost completely removed Microsoft Office from my work-flow. One hurdle remains, though -- sending scientific manuscripts out to colleagues for comments. Everyone I know simply uses MS Word's Track Changes feature for this. To tell the truth, this works quite well. However, I'd prefer to use free software to write my articles, like LaTeX or OpenOffice and then distribute PDFs or host HTML files for people to look over. I've been working a bit with Multivalent, which is very promising, but still firmly in alpha. Are there any other free, cross-platform tools for collaborative marking up of PDF or HTML (or other) documents, a la Word's track changes feature?"

jSpectre asks: "At my new job the Unix SA team has increased from 5 to 7. We're trying to work out a new, rotating on-call schedule and everyone has 'perfect' but conflicting ideas. Twelve weeks on and 6 off, 25 weeks on and 10 off. I thought someone out there must have come up with the perfect formula given N number of people you could rotate through the weekdays and weekend most efficiently. My google and web searches have come up with nothing. Does anyone know of a good formula/solution? The requirements are this, we have 7 people (but the forumla should ideally apply to N people) who should rotate through the weekdays (a 24 hour period) and the weekend (a 48 hour period). There is a desginated primary and a secondary person. They should be on for a few weeks and off entirely for a few. Sound like a good thesis/research problem for someone? By the way, Google comes up with a lot of people's schedules if you search for pager rotation. Tisk tisk."

Controlio asks: "With the explosion of cell phones, pay phones are disappearing quickly. I work in a large sports venue that seats over 60,000 - but has only 5 pay phones. The problem is the rent on those 5 phones is ridiculous - we net a loss of over $150 per phone per month. Its a great convenience for the public, but it'd be cheaper for us to have people stand in the middle of the stadium with cell phones saying "here, make a call for free." We have a great deal of both telephone and internet capabilities - we're a brand new facility and have far more than adequate data and voice pipes to our building. The question, is how can one roll their own payphone service? Has anyone done this? Where can you purchase equipment? What are the technical ramifications if we want to stay basic or get complicated with things like TTY or internet phones? Does VoIP or POTS make more sense? Any advice on where to get started?"

arashiakari asks: "I have to buy a new laptop soon and I am having trouble settling on a brand or model except one that I cannot use. Apple's iBook laptop is beautiful, functional, lightweight, and made of high quality materials. I would buy one today except that I am a professional programmer and MUST use the same platform my compiler targets: Intel. So far each Intel-based laptop I have looked at is both grossly over-decorated (Compaq, Toshiba) and made of cheap flimsy materials (Dell), or has the combined problem of being overpriced and under-powered - with external bays for everything (Sony). IBM is expensive, but they are as close as I've found to "right" ... with Toshiba in second place. It seems like Intel-based laptops are either hot ugly tanks or oversized PDAs, there seems to be a scarcity of balanced well-thought-out and produced machines. Does the Slashdot have any suggestions?"

wowbagger asks: "We've all heard of the various apt-get packages for Mac OS X (and more power to them!), but does anybody know of a similar effort for Irix? Yes, SGI has their freeware distribution of GNU and other utilities, but there is as far as I've seen no good way to automatically update - you just have to go to the SGI open source server (when it is available) and try to find something new. Has anyone set up a apt/gentoo/redcarpet system to automate this process"
