Best Linux Hardware Diagnostics? 42

An anonymous reader asks: "I've been running Linux for a little while and usually hardware problems have shown up quite easily - kernel panic, no module, no networking, etc. - but recently I've encountered some problems with network disk access causing very high load, which I think might be hardware related. Under Windows I'd fire up SANDRA or the like and run a full system scan. I did a quick search and nothing really stood out. I was wondering if any Linux gurus out there would like to share their expertise on Linux diagnostics?"

Risks of Partisan Spam Filtering? 63

Mike1024 asks: "Pete Klammer reported in RISKS 23.95 about spam filtering software filtering political e-mails - including Postini blocking certain anti-Schwarzenegger URLs and Comcast blocking e-mails mentioning afterdowningstreet.org. This could be caused by malicious action, misreporting of spam, 'joe jobs', or actual spamming. With many people using their ISP's default settings, and manual spam filtering being impractical for many users, what can be done to avoid giving ISPs and anti-spam companies extensive, fully automated censorship abilities?"
Privacy

Using Technology to Protect Anonymous Sources? 450

A not-so Anonymous Anonymous Coward asks: "The New York Times has a story describing how newspapers are looking for new ways to hide the identities of anonymous sources from prosecutors. This seems like a something the Slashdot crowd might know something about. How can a newspaper setup an IT system that completely hides every trace (including emails, phone calls notes, logs and so forth) of an anonymous source's identity?"
Security

Towards a Comprehensive USB Flash Drive Policy? 121

sconeu asks: "The company I work for is going through some growing pains. This is a -good- thing, but due to the growth, some changes are necessary. I'm the guy who does IT and IT policy, however I'm actually a developer by job description -- I was doing IT on the side. Anyways, we're going through growth, and one of the things we are trying to address is security. Currently, our policy is wide-open (for internal machines). The owner has expressed some reservations about the increasing use of flash drives, in an overall security setting. Everyone involved here realizes that there's not much we can do against a malicious employee, but we're looking to avoid accidental data loss from USB sticks, and other solid-state storage media. Has anyone on Slashdot dealt with this issue? What policies and protections did you end up putting in place, if any?"

Brain Teasers for Coders? 109

calvinandhobbes asks: "There are about 200 people working on different projects and most of them do programming without having an idea of what they actually do. they have little understanding of OS internals and primitive hacking skills. I want to enthuse them by providing some challenges by which they touch upon complex computing concepts, while solving the problem. Does anyone know of a set of C-based hacks or puzzles with which I can enthuse these budding programmers and testers?"

Ian Clarke and Freenet in the Crosshairs 493

EMIce writes "John Markoff of the New York Times writes of Ian, "Though he says his aim is political - helping dissidents in countries where computer traffic is monitored by the government, for example - Mr. Clarke is open about his disdain for copyright laws, asserting that his technology would produce a world in which all information is freely shared. ... Now, however, Mr. Clarke is taking a fresh approach, stating that his goal is to protect political opponents of repressive regimes." Wasn't freenet originally about dissent? Mr. Markoff appears to be re-writing a history that he probably only knows through a handful of lexis-nexis searches." Update: 08/01 18:32 GMT by T : Ian Clarke wrote to point out his comment posted to the story which lays out the actual subject of his Defcon talk.

No More Codewarrior for Mac OS X 84

wandazulu writes "According to an announcement posted on the Carbon developer's mailing list, Metrowerks announced at AdHoc that the forthcoming release of CodeWarrior 10 will be the last for Mac OS X. This isn't surprising given that Apple is transitioning to Intel chips and Metrowerks has exited the Intel market, but it's still the end of an era. CodeWarrior literally saved Apple's bacon during the transition to PowerPC in the early 1990s by shipping the first working set of developer tools for the new platform. And since then CodeWarrior has been the main toolkit for commercial development on the Mac (especially pre-Xcode)."

Time Syncing Through a Firewall Without NTP? 112

dvdsmith asks: "Say are dealing with a Windows network that for internet access must pass through a firewall that you have no control over. Said firewall apparently blocks the known time protocols (NTP,daytime,etc) and you know from experience that those who control it will not allow any exceptions. If one sets up an internal NTP server (Windows XP or 2000 workstation) for all others to sync from, is there another reliable method for updating time on the server, like pulling from a Java website? See the time.gov website as an example. Any ideas?"
Programming

Choice of Language for Large-Scale Web Apps? 801

anyon wonders: "PHP is the most popular language for the web. eBay uses ISAPI (C), Google uses C/C++ (search), Java (gmail), and Python. Microsoft uses ASP (what else?). For small web site, it really doesn't matter. What's your take on language choice for large-scale web applications? Maybe language choice is irrelevant, only good people (developers) matter? If you can get the same good quality people, then what language you would chose? Considering the following factors: performance, scalability, extendibility, cost of development (man-month), availability of libraries, cost of libraries, development tools? Has there been a comprehensive comparison done?"
Spam

Classed as Spam by Large-Scale Free Email Servers? 86

bartle asks: "I run my own personal domain that serves all of my email needs of myself and a few friends. In general this has worked out pretty well but there's a fairly significant limitation: if I send an email to a Hotmail or Yahoo account that I've never contacted before it tends to get filed as spam. This means that if I'm writing someone out of the blue I need to send an email from a free service which kind of defeats the purpose of running ones own email server. My domain has a SPF record, the IP resolves, and it doesn't appear to be on any blacklists. I can not find any documentation on what hoops I need to jump through before Hotmail and Yahoo will consider my mail legitimate. I understand that there's a general paranoia about publishing information that could assist spammers but this attitude seems to be leaving do-it-yourselfers out in the cold. Does anybody have any ideas? Are there guidelines or protocols I can follow to make my email non-spam?"

Computing in Rwanda? 56

gehel asks: "In September I will be going to Rwanda, working for a year in a developement project as a Computer Science guy. I'm leaving with an association that doesn't have much experience in sending CS guys over there, but I'm sure some Slashdot readers have some experience in that field. For all those who know Rwanda or Africa better than me, or for those who have been working in developement projects: What should I be prepared for? What would you bring with you to go there? How do you think we can bring Computer Science to a developement project in Africa, without creating too much dependencies on the North? What are the typical failures of such projects?"
Wireless Networking

The Case for Free WiFi? 576

lgreco writes "Recently I was trying to convince a business man who is about to open an Internet Cafe, to provide WiFi at no charge. I argued about increased business and royalty and proposed that the infrastructure cost these days is reasonable and the recurring cost, along with the amortized payoff of the initial investment, can be recovered by adding a few cents to each beverage, etc. In spite of the numerous discussions on the merits of free WiFi v. paid at coffee shops, restaurants, etc, I was interested in hearing what do you think about the issue and if there are solid examples of successful businesses that offered free WiFi." If you were going to argue for or against this issue, what arguments would you use?

Best TCP/IP Stack Implementation? 151

paultantk asks: "This mailing list suggests that the FreeBSD TCP/IP stack is sub-par. It was the best in the 90's, but not anymore. So the question is, which operating system now holds the title for the best TCP/IP stack implementation?"

Planet X Larger Than Pluto? 561

nova_planitia writes "The Minor Planet mailing list is buzzing with the discovery by an amateur astronomer of a 17th magnitude object 51 astronomical units from the Sun, tentatively designated 2003 EL61. For those not versed in astronomical lingo, this is an object several times brighter than Pluto even though it is 25% farther out from the Sun (the orbit vizualised by JPL). This means that barring a strangely reflective surface, this object is larger than Pluto, possibly Mars-sized! The debate whether Pluto is a planet is likely to get rekindled by this discovery."

Transferring Mail from AOL? 102

Bazooka Joel asks: "My father has been a long time user of AOL. He subscribed to AOL's dialup service about 5 years ago and created his first email account with their services. We now have cable internet from a local company, but he still pays $15 a month just to access his email. I have tried to get him to switch to Gmail, but he is stubborn. He finally relented and said that if I could forward all of his old mail (thousands of messages) and import his contact list into Gmail, he would cancel his AOL subscription. After searching the 'net, I found a way to import his contacts. However, I cannot find a program that will forward all of his old mail. Can anybody lend me a hand?"
