What About "Smart" Credit Cards? 333

Platypii writes "After seeing many ads on TV and around the Internet for the "smart" credit cards (both major companies now have them I believe), I became curious about them. The Visa website was rather vague about it, and only proclaimed dreams of merging all your cards -- of whatever type -- into one. Anyone know the technical details of these cards? The privacy aspects?"

ALSA vs. OSS vs. OSSFree 32

scenic writes "I was wondering what experience the /. community has had with ALSA vs the sound drivers that are part of the Kernel and the various other choices (such as the 4Front OSS packages). I've used the commercial OSS drivers as well as the "included" Linux drivers. I've started to look to ALSA for better sound response (for example, I've noticed with esd and the basic linux drivers, there is sometimes a lag when playing back video files through esd. I understand that esd is part of the issue, but it's sort of important to be able to multiplex sound). What have others' experiences been? What other solutions are there aside from things like esd?" Which sound systems do you find work for your system, and which don't? If specific hardware / software combinations can be endorsed or critiqued, it'll probably help a lot of people.

What Happens To -AC (And Other) Kernel Mods? 164

RedLeg wrote with this poser: "So, looking at the changelog for the 2.4.9 kernel release, I see a few '- Alan Cox: driver merges' entries. Intelligent consumers of (or those of us who modify them for our own uses) RedHat Kernel src.RPMs look at the patches in the RH kernel builds. Alan's (and other persistent RH) patches don't seem to be integrated into Linus' 'mainstream' kernel trees on any kind of a predictable basis, and this frequently causes projects like freeswan to have difficulty merging their patches (not intended for kernel inclusion) with kernels that appear 'in the wild' like the kernel RPMs from RedHat. Often, kernel patches for obviously older kernel versions continue to be applied (in the RPMs) to newer kernel versions. Alan is a RedHat-er, so he obviously has an inside track to RedHat kernel builds, but he's also Linus' Right-Hand man, but his patches are not (apparently) consistently making it into the 'mainstream' kernel. What am I missing?" Who better to answer this question than Alan Cox? Alan was kind enough to write an explanation of the (still complicated) process of merging -- and it's not as simple as who works for what distro maker ;)

Internet Connectivity Options in Mozambique? 16

watanabe asks: "I'm going to help a relief organization in Mozambique this autumn, and have been talking to them about how to get their Internet services up and running better than they are now. They have 1200 physical sites, most of which are deep in the bush, and two cellular modems which connect to the national ISP. A major problem they have is sending e-mails to interested supporters; frequently their ISP drops large numbers of the e-mails, and doesn't tell them about it. Do you all know of any high speed options / LEO satellite / commercial companies that support businesses in Africa? I've been puzzling through how to get them better services, but I'm sure the collective wisdom of the Slashdot community is greater than what I can turn up on my own."

Keeping Audit Trail of Activities from Root Login? 44

supersam asks: "This question might sound a bit naive, but I am comparatively new at this. So, here goes: on one of my application, based on UNIX platform, I need to implement a mechanism by which, I can trace when an access to ROOT was attempted and what all actions were performed during that session. While info on the first part is probably available through UNIX logs, the second bit is difficult to me. The need is arising because, while it is useful for the support team to know the ROOT password as most of the wonderful things can be done with that access, it also can be a nightmare if something goes wrong and we have to trace the culprit or the root cause of the problem (config files etc...). Is there any way of keeping an audit trail of all activities performed from ROOT login in UNIX which can be traced." Interesting thought. About the easiest way to do this would be to give root it's own custom shell and log everything that shell does. Are there shells that can already do this? Has anyone else implemented such a system? If so, what did you do?

What is Happening with OpenGL? 576

Trapped In Windows Hell asks: "I was just at the local game store looking for a new game, and I noticed the absolute lack of ANYTHING other than DirectX games. Where has OpenGL gone, and what does this mean for games on GNU/Linux? If DirectX is so hard to program in, so clunky to use, and limits the game to being sold on only one OS, WHY do so many programmers use it? It seems logical (to me, at least) that programming as portably as possible, as simply as possible, and using standards where possible, leaves a lot more sales options open for the future... and DirectX seems to close all options *but one*." OpenGL use in Windows gaming has decreased dramatically in favor of the use of DirectX which is improving with each release. Will OpenGL continue to mature on the Windows platform (which arguably is the platform that drives most of the mainstream demand for graphics) or will it continue to stagnate as game and driver developers concentrate on the offerings from Microsoft?

Leveraging Cheap PC Hardware? 9

dsginter asks: "Now that PC hardware is dirt cheap (under $100 for a Duron 700, motherboard, LAN, modem, sound, etc), I would expect to see more in the way of leveraging this sort of hardware for uses outside the home and office. Is there any vendors out there who address the need for cheap 12 volt DC power supplies? How about vibration tolerance (besides Flashdrives how are you getting the processor and accessories attached reliably)? PC/104 is comparatively expensive so it would be nice if there were some solid-state, 12-volt, embedded (and possibly even real-time) Linux projects out there. Example: with RAM as cheap as it is, you could make a portable digital video camera for very cheap. Are there packages out there or is this strictly DIY?" So where can you go if you are looking to purchase decent hardware for your embedded projects? Are any of you attempting to assemble projects like this? If so, what kinds of things are you working on?

Getting Opera to Work with Hotmail? 17

theComposer asks: "I use Opera as my browser of choice. Ever since Microsoft changed it's Hotmail interface, I've been having "issues". If I set Opera to identify itself as Opera, Hotmail won't let me look at my mail. I get a screen that tells me to upgrade to the lastest Internet Explorer or Netscape. However, if I set Opera to identify itself as IE, I can log in just fine. Once in (with Opera), I can't check an email and delete it or move to another folder or whatnot. I had no problems using Opera with Hotmail before the interface change. It goes without saying that everything works fine in IE. Does anyone else have these problems or am I doing something wrong here?" It goes without saying that this kind of behavior is expected from Microsoft, nevertheless, has anyone gotten Opera to work with Hotmail? If so, what tricks need to be performed? If anyone else is having problems with a non-IE browser when accessing Hotmail, please share your experiences.

Handing Over Root Passwords to Clients and Contractors? 24

waa asks: "I have a client who's system I remotely administer. This particular machine has been up performing its various duties 'problem-free' for 4 months (since last kernel patch/fix). The client has, on-site, a consultant who pretends to know things he certainly does not know; Linux systems administration for one, and they now have requested the root password. Since it is their system, I'd imagine they have every right to the root account, however I know for sure that as soon as this is handed over, things will start to mysteriously malfunction, and I will get an emergency call to get them back in service (or worse, I will be blamed; ie: back-stabbed). I'd rather not have to troubleshoot and fix a completely preventable, and possibly complex problem. What are peoples' experiences regarding this situation? How have you handled it? Is some form of 'release from responsibility' contract in order? I need some advice soon" In situations like this, communication with the client is important. If you ever run into a situation like this, talking to the client and informing them of the potential problems is always a good idea. If any problems happen afterward. Start documenting them, and pass them back to the actual client if things start to become a problem. Anyone else care to weigh in?

How Can I Make More Of My Cubicle? 473

Dorm Storm? 628

The Ape With No Name writes: "I work as a network technician at a major Southern university and we are gearing up for what is lovingly called "Dorm Storm," aka the weekend the students return to their dorm rooms, ethernet connections and BearShare. We'll move in approx. 3500 students, install and configure 1500 or so network cards and troubleshoot hundreds of circuit, switch and routing problems over the course of the next two weeks (with less than 50 people or so). I was wondering if anybody out in the academic computing community had some advice, stories to relate, yarns to spin for the rest of Slashdot with regard to other universities and their networking for students. You might think you have had a hell of a time setting up machines for users, but this becomes a Sisyphean task when you face a wireless, IP only, Novell setup for a grumpy architecture student on a budget Win2K laptop - one after another after another!"

Acknowledging Great Free Software 281

banuaba writes: "I am a Windows user. I've tried a couple of distros of Linux, and a BSD or two, but they aren't what I need in an OS. Sometimes in my job and my personal 'life' I need something with a little more power than Windows can give me, and when that time comes, I use Cygwin and have been wholly satisfied and enamored with the product they put out. My question for all you Slashdotters out there is this: I would like to 'reward' the Cygwin people for giving me a great product that fits my needs, but aside from an 'attaboy' email, I don't see how I could compensate them, preferrably financially. I don't have any coding skills of significance, and am not inclined to learn, I'd just like a way to let them know that I like what they've done. In the non-free (as in beer) software world, I would buy their next release. Is there any way to financially help them along? Should I just mail them a check? Would that be insulting to OSS developers, as a general rule? How or would you slashdotters who work on GPL'd code like to be compensated for your time and effort?"

Best "Visual Studio" Alternative On Linux 82

Microsoft ISV writes: "We are beginning the next major release of our product, and we have been a Microsoft ISV for many years. In a few months Microsoft will be entering our market, and we wish to hedge our bets by supporting Linux in this next new major release. Can you ask your readership what is the best 'Visual Studio' like IDE for Linux? Especially for an ISV who will be maintaining the same product on both Windows and Linux?" Or is there even such a thing?

Memory Leaks 34

G3ck0G33k writes: "Is there any free software version/clone of Rational's programs PureCoverage and/or Purify? I have worked with both of them on fairly large projects (>150,000 lines of code) and they were great to work with. When the first runs of Purify found nearly fifty instances of minor memory leaks, I was deeply frustrated/impressed. A free (perhaps GPLd) clone would be so interesting; Rational's licensing is killing my current budget. Of course, the more kinds of leaks it may detect, the better. GeckoGeek" We had a similar question last year but there's no harm in seeing what the current answers are.
