Bi-Directional IP Over Satellite? 51

Kranky asks: "My company is looking at doing bi-directional TCP/IP over satellite, ie. data over satellite with a satellite backhaul as opposed to modem backhaul, and being the solo IT pleb here I was wondering if anyone had any recommendations for gear to use to achieve the goal or if they'd done similar and could give any pointers. Basically we're looking at 512kb/s [in both] directions and I'm wondering what sort of gear we'll need for the link, as well as any tips towards curing the inevitable latency issues. I assume there will be a cache and routers at either end (remote site will use us for internet access) but having never come across doing this whole IP over satellite thing before I have no real idea what we'll need. Any recommendations, pointers, or links would be appreciated."

ISPs That Actively Combat SPAM? 45

The Llama King asks: "Like a good netizen, I do my part to report spam. But most Internet providers merely respond with a canned e-mail and it's hard to tell whether action was taken - or when. I know a lot of abuse desks are overwhelmed and spammers can get a free ride if they pick their targets carefully. Occasionally I'll get a personalized response, and even notification that a spammer's access and/or Web site has been nuked - but that's rare, and seems to be getting rarer. What ISPs are best at responding to spam complaints in a timely fashion, both in terms of killing e-mail accounts and shutting down sites that have been spamvertised?"

Realistic Portrayals of Software Programmers? 874

lwbecker2 asks: "Warren Harrison has written a thought-provoking editorial piece on The Software Developer as Movie Icon. He explores the fact that new entrants to Computer Science curriculum are typically clueless about what 'real' developers actually do. While researching the issue of why this is the case, he determined that some potential CS degree seekers are forming opinions from portrayals in movies and cinema. He describes what he asserts to be inaccurate portrayals of developers in War Games, TRON, and The Net, and asks for input and opinions on 'the impact of the cinema and television on new software developers' expectations, as well as learn of any films that do a better job of portraying our profession...' I am sure Slashdot readers have some input on this, and I am curious if people believe _any_ movie has acurately portrayed software developers?"

Remote Access Solutions for Businesses? 45

thajeavis asks: "We are in the process of replacing our existing remote access system for IT staff and other faculty/staff. Previously, we were using a Bay Networks (Nortel) Remote Access Concentrator with an ISDN circuit. The equipment failed and the cost of the ISDN PRI is too high based on the low usage. We are presently testing a VPN solution using the employee's own dialup or broadband connection (Cable/DSL). The issue has also come up over who is to pay for the dialup/broadband connection, the employee or the college since it will be used to work from home. I am most interested in what type of solution your institution has in place for remote access for IT staff and who pays for that access. We also are interested in what type of access, if any is available for other faculty/staff. Any insight on this issue will be greatly appreciated."

Best Practices for Writing LDAP Aware Apps? 33

Saqib Ali asks: "I am in a process of writing a web application, that makes quite a lot of transactions with the LDAP server. I would like to find out, what are the best practices in encrypting the traffic from the web application server to the LDAP server. I understand, I have few choices: SSL, TLS/SASL (supported by SunOne/OpenLDAP), and the traditional STUNNEL. Any ideas, on the best way to provide encryption? . What is the value of 'encrypting everything' and cost of encryption (encryption is process intensive)? I would also like to locally cache the data I receive from the LDAP directory. Are there any solutions for doing that? Or should I just cache the data in a SQL database running locally on the WebApp server?"
Games

Free Repository for Tile Graphics? 24

Hentai asks: "I want to make a game. Specifically, I want to make a good, open-source computer RPG, with the same artistic style of the early Squaresoft sprite-pushers, like Secret of Mana and Chrono Trigger. I can code well enough, and I can get artists to provide character sprite graphics (which will be open-source, too), but I need background tile graphics on the same vein and caliber as those titles. Web searches invariably lead to commercial or shareware packages, or 'free to the public' tile sets that are, frankly, abysmal. I just need enough quality tiles to start with, and will happily add any new derivations to the repository. Anyone know of a good GPLed tile package that could get me started?"

Buying a Small, Light Linux Notebook Computer? 1048

metamatic asks: "I'm planning to buy a notebook computer in the near future. Currently I'm looking at an iBook; however, they're a bit larger and heavier than I'd like. PC users are always telling me that PCs are faster and cheaper, and I'd be happy enough running Linux for what I want the notebook for. So: I'm looking for PC notebook computers that outperform the iBook. Must have USB and Firewire, built-in ethernet, and 802.11b support somehow (via a PC card slot is OK). Small is important, lightweight is important, long battery life is important. I don't care about screen size so long as it can do 800x600. Performance isn't a major concern, as I'm not going to be playing 3D games on it. Sounds easy? Here's the catch: I will not purchase Windows!" After all that this industry has gone through in recent years? Does one still have to pay the Microsoft tax when purchasing a laptop?

Cancelling your Passport.NET Account? 38

An anonymous reader asks: "i read on the Passport.NET site that 'Microsoft has announced plans to discontinue the .NET Passport express purchase service' AKA .NET Passport wallet. This may well be old news but the reason i stumbled on it is I want to discontinue my Passport account. There is a link on the account maintainace page that allows just this - however it bounced me to my Hotmail account which I had to close first. However my Passport account is still open and when I try to close it I just get bounced to the Hotmail reactivation page... (the reason i am so hyper about this is anger at being automatically opted-ini to two seperate information sharing schemes without being asked - no wonder there was so much spam! Have any of you had a similar problem closing your account? Has anyone managed? If so how?"

Intrusion Detection Systems for Gigabit Networks? 11

caelyx asks: "I've got to evaluate various IDS solutions for use on a gigabit network. While I've had experience using and configuring snort, I haven't used many of the commercial solutions (Dragon, RealSecure, ManHunt, etc). I guess I'm mostly concerned with signature quality and depth, the power of the analysis console(s) and a robust engine that won't drop packets on a busy network. What experiences have Slashdot readers had with various NIDS or hybrid NIDS/HIDS solutions? Suggestions?" Ask Slashdot last touched this topic in this discussion, but it didn't focus on the needs for a Gigabit network. How well do the solutions mentioned therein perform on such a high end network?

Keyboard Layouts for the 21st Century? 1044

jules asks: "Trying to do some programming on an iBook the other day brought to my attention the fact that despite the constant improvements to the design of computer hardware and software, the keyboards we use are still a throwback to the early 1980s. I mean - my Mac doesn't have room for page up/down or home/end keys, but it devotes a whole key to a sort of double-S shape that I will never press. And my PC keyboards all waste plastic on a backwards-apostrophe key and a scroll-lock (+ LED!), while functions that you use all the time, such as switching between windows, cut/copy/paste, back/forwards, undo/redo etc, all have to double-up with other keys.. Have any organizations actually tried to re-invent the keyboard recently? (..not counting the manufacturers who stick a few 'multimedia' keys along the top for consumer PCs). Would this be doomed to failure because of the tens of thousands of legacy apps that expect things to be the way they are? What sort of keys would you include in your fantasy keyboard layout?" It's not just the keys on your keyboard that are important, it's also how you arrange them. What kind of keyboard arrangements might we see in the future?

The Ultimate Computer Desk? 67

Roonster asks: "I've just moved into a new house and I am now lucky enough to have a separate room to use as a computer room/office. I have been searching for a new computer desk but most of the standard offerings seem to be lacking in imagination and design. I also tend to sit in a reclined position with my feet up on the desk beside the monitor, this eliminates a lot of the corner and U shaped designs. Have any of you come up with unique yet functional desk setups? I remember seeing some really wild (and expensive) workstations a few years ago, but have been unable to locate them recently. Any Ideas?" This topic was last discussed some 2 years ago. I figured it was time for a rehash.

Open Source for SETI Software? 27

CommonModeNoise asks: "The SETI Institute is thinking about going to an open source model for some of our software. We have little experience with Open Source so we would like to ask the following: To what degree can an open-source project be self-managing -- how many of our staff will be needed to keep such an activity running productively? How can we deal with the lunatic fringe that will be attracted to something as provocative as SETI? Can open source development proceed at the same speed as traditional in-house development, or will it be slower? Some of our software controls hardware, for example the Allen Telescope Array; can such control software be developed using open source methods or are we better off focussing on the software-only systems, such as the next generation of our signal detectors? Finally, could we please get some suggestions as to what to read to get a better grasp of the varieties of open source development models and their respective good and bad points."

What Math do You Use? 102

e_lehman asks: "I've been associated with MIT's introductory 'Mathematics for Computer Science' course for a number of years. The course has emphasized different topics in different years: logical foundations, proofs, probability, combinatorics, etc. But this is at the whim of instructors. What mathematical topics should we be teaching to budding computer scientists? What mathematics do you actually use or need, working in the computer industry? Here are some candidates: boolean logic, graphs, number theory, combinatorics, proofs, set theory, relations and functions, approximation methods, solving recurrences, generating functions, analysis of state machines, asymptotic analysis, and addition of small integers."

FTP: Better Than HTTP, Or Obsolete? 1093

An anonymous reader asks "Looking to serve files for downloading (typically 1MB-6MB), I'm confused about whether I should provide an FTP server instead of / as well as HTTP. According to a rapid Google search, the experts say 1) HTTP is slower and less reliable than FTP and 2) HTTP is amateur and will make you look a wimp. But a) FTP is full of security holes. and b) FTP is a crumbling legacy protocol and will make you look a dinosaur. Surely some contradiction... Should I make the effort to implement FTP or take desperate steps to avoid it?"

Software to Read/Convert a Folio Infobase File? 18

garyebickford writes "Infobase is an application and data format that appears to be very popular among various governmental agencies. It is apparently also used to produce many CD/DVD titles. The 'Folio' software to read and write Infobase files is evidently now produced by NextPage Inc.. (Note: in order to get their page to come up, I had to set Opera to say it was Explorer). In my case, I have been given an Infobase file that contains, to my knowledge, public domain material. However the software to read it is Windows-specific, and I am resistant to the idea of buying a Windows box just to read it. I tried contacting the company that produced the Infobase, but the support number for the company is no longer connected, and their email address bounces. I seem to have an orphan dataset. I have looked fairly extensively for any open source software that can read or write the Infobase format, without success. Does anyone know the format, or (bless you) have an algorithm to unpack the data?"

A Clearinghouse for Linux Market Data? 21

avdi asks: "Every day we see stories on this site and others about how another movie studio is using Linux for production, another Fortune 500 company has switched to Linux to support their infrastructure, another local or national government has mandated use of Open Source technology, or another major vendor has begun marketing a Linux-based product line. Clearly Linux, Open Source, and Free Software has arrived, and in some areas is marching towards dominance. Yet deep in the beige-walled cubicles of the biggest corporations, where Nobody Ever Got Fired for Buying Microsoft (or Sun, or...) the people who make technology decisions have yet to hear of it. In the land of BigCo, Open Source technologies have an artificially low profile due to the insularity of the corporate culture, the marketing budgets of vendors, and are often viewed as risky, untested curiosities. Is anyone out there gathering all the success stories together in an up-to-date, management-readable format? Is anyone collecting hard data on the number of major companies which have trusted mission-critical systems to Linux, the number of vendors who have invested a significant amount in Open Source-based product lines, the amounts saved by various departments which have migrated from proprietary to Free software? Where does one go when researching data in order to sell management on Linux or some other Free Software solution?"

Appeal for Linux Help from Pedal-Powered Internet? 13

lma asks: "As has been reported previously on Slashdot, Lee Felsenstein is involved in a project to bring wireless internet connectivity (including VOIP) to isolated villages in Laos. Lee is in Laos this week, trying to install and configure the initial systems. He's having a problem getting Linux installed and booting off a M-Systems DiskOnChip(DOC) as described here. Perhaps Slashdot readers could help with this problem, and make themselves available for future technical support issues as well."
