Cheap Point-To-Point VoIP Through NAT? 35

An anonymous reader asks: "70% of my phone bill comes from calls to a few colleagues. We all have 'broadband' internet access (at least 100 kbit/s upstream) and are behind NATs, so we can share our access with the rest of our house-mates. The OS most used is Linux. In order to lower our phone bills I'm looking for a Point-to-Point audio tool which enables you to pass relatively easily through the NATs. I've had a look at Speak-Freely, which is quite nice as it sports things like GPG-encryption. But it uses two UDP and one TCP ports which is a bit much and not very NAT friendly. I wouldn't like to use commercial tools with central servers like Skype. What would be ok is to use a webserver to serve as a kind of starting point where you would update your IP address and ports. But it should be possible to give your mom and pop webhoster to set up or even better just a cgi-script which interacts with the clients via http or https. The audio data itself shouldn't be routed over a server (what a waste of bandwidth). Thanks for all ideas."

How To Manage Your Home Directory? 176

gustgr writes "There are times I got surprised after running ls in my $HOME directory. It is filled with trash, test files, directories that were supposed to be only temporary, ascii files with quick notes and all sort of stuff. In other words, it is a complete mess. Then I remove the trash, clean up the directories, run the mv command a few times and everything looks good and normal again. Two weeks later the disorder is back and I have to handle it again. How do you manage your home directory in order to keep it clean? Are your homes a mess too?" I usually keep folders labeled "audible," "visible," "legible," and "work," and subfolders within these that are at least mostly consistent between computers / drives; every day or so I sweep loose files into these, then open each folder, sort, repeat. How do you sort your data?

Best Live Linux For Christmas Giving? 594

trustedserf writes "This year I am including a bootable Live Linux CD in many of my Christmas cards. As I'll be making the copies myself I may even change the default desktop background to something personal, or Christmasy before running it off on cheap CD-Rs. The objective is to show people the easiest possible route to using a linux desktop so that they will be: A) Aware and B) Pleasantly surprised. About Christmas they may also have more time to try it out too. Naturally, I'm thinking of Gnoppix, but there are other options.. I use KDE, so I have to decide between it and Gnome. Bearing in mind my objectives, what distro would you choose. Also, importantly, is it possible any of them will damage their hardware (monitors with incorrect refresh etc.) I would be *very* unhappy if that happened. How many of them would fail to boot, leaving a bad impression? Which way would you go about it for maximum "WOW"."

Review: Half-Life 2 769

The original Half-Life is regarded widely as a defining moment in the first person shooter genre. The game's use of story and in-game scripted elements changed the expectations of game players and spawned a bevy of imitators. The sequel, Half-Life 2, has been in the works for almost six years and is one of the most hyped and anticipated games of 2004. It was launched last week after delays, a code theft, and lawsuits frustrated the anxious fans waiting for a chance to play. Post-launch the game has received wide praise and, thanks to the unique distribution and authentication system called Steam, many complaints as well. Read on for my impressions of Valve's Half-Life 2.

UNIX Systems Control Politics? 133

pariahdecss asks: "I have just been hired as the webmaster for local college. The website for which I am responsible is hosted 'in-house' and controlled by the college. The server box does not have any other production systems on it besides my website. The website that I have inherited is driven by an amalgam of Embedded Perl and PostgreSQL. Now to the politics...the UNIX Administrator does not want to give me root access to this box. What have others done when faced with this type of systems politics? Is it even possible to function as a full scale webmaster without root access to the box you serve from?"

Is Firefox 1.0 Less Stable than Firefox PR1.0? 758

An anonymous reader wonders: "I had Firefox 1.0PR running smoothly on three different machines and it hardly ever crashed. After upgrading to 1.0, I seem to have at least one annoying crash a day. On one of the machines, using the 'self update' feature caused Firefox to crash in middle of the upgrade and left it in a completely unusable state. Eventually, I had to uninstall it and resort to using IE to download the full installer, again. Is it just me, or are other heavy Firefox users noticing this sort of behavior?"

Building a Small Autonomous Robot? 43

Nedward asks: "For Christmas I would like to give a friend all the equipment to build a small (approx 1 ft^3) mobile autonomous robot. I have looked up some kits online, but I would like more freedom than the kits offer (fully programmable, etc). The challenge: I only have $200.00 to spend. Has anyone put together a robot (CPU, motor, sensors and so forth) with that kind of a budget? Any other suggestions?"

3D Display Hardware/Software Solution? 27

Daemon8666 asks: "I've searched for three days with no luck. A client of mine has developed a brand new type of 3D display. To make it work, he needs me to come up with a way to synchronize 3 simultaneous video feeds on one box, and output them to 3 separate devices, as follows: Comp playing Videos A, B, and C in sync, and outputting Video A to Monitor X only, Video B to Monitor Y only, and Video C to monitor Z only. He is currently using 3 off-the-shelf DVD players that he controls with one remote (he pushes play, and all three separate DVDs start together), but he really wants a single-unit solution. Any ideas what hardware/software I should use?"

How Good are the DNA-Drivers for ATI Cards? 67

dark_requiem asks: "I've been digging around online to find some way to pump a bit more power out of my Radeon 9800 for Half-Life2, and I ran across DNA-Drivers. According to the developer, these are hacked versions of the official Catalyst drivers, optimized for speed and image quality. I've been trying to find a good review of the performance of these drivers, but haven't found much. Has anyone tried these before? Are they stable? What kind of performance advantage do they offer?"

Professional CD-R and DVD-R Burners/Duplicators? 41

burnWell asks: "I work for a software publisher, and when preparing CD media for final distribution to the manufacturer (the Gold Master if you will), we often find that our CD and DVD burns are not very good quality. Are there any recommendations for professional grade, highest quality CD-R and DVD-R writers? Are there any tools or metrics we should use to verify how 'good' a particular burn happens to be, and to that end, how well behaved some brands of media are versus another? Are there recommendations for the very highest quality CD-R and DVD-R duplicators?"

Does Anyone Still Play-by-Mail? 114

manganese4 asks: "With the ever increasing complexity of games and the desire to buy the bleeding edge of hardware, does anyone still participate in games in the old-time 'Play by (e)Mail' format? Remember the anticipation of wondering if the snow storm was going to delay the post and prevent you from executing a crushing blow with your rook or pacing your emails to give your opponent time to become distracted by something else on the Usenet groups!"

What is the Tech Jobs Situation in Late 2004? 1138

CareerConfused asks: "Today I came across an ad in the NY Times, put out by Microsoft, Micron, Level 3 (among others) that claimed that the H-1B visa quota for FY2005 has already expired (it claims the quota expired the first day of FY2005, which started just about a month back). OK. On the one hand, we have stories of techies not finding jobs; and on the other, we have stories from businesses which claim that lack of H1s is killing their business, as well as public advocacy (like that ad in NYT). So, what is it? Are we in another boom, with jobs going a-begging and companies requiring more H1s to fill them? How come I haven't noticed this in the form of a fatter paycheck (or an Aeron chair, or a fooseball table in the cubicle)?" What have you experienced in your searches for technology-based jobs? Is it still hard to sell your hard-earned skills or are things looking up?

How Do You Keep Up with Enterprise-level Tech? 41

A user asks: "I'm curious how the Slashdot gang chooses to keep up with the performance of high-level equipment for servers, routers, loadbalancing, and the like? For PC-type specs it's easy, every guy and his dog has a review website, and magazines stuff themselves in every window. However, the higher-end equipment is far more difficult to find trustworthy analysis of. I'm curious how other people have solved this problem, and what resources they use to keep on top of the game?"

HDTV PC Capture Solutions? 291

Akai asks: "With HDTV DVR's costing upwards of a thousand US dollars or more, I was looking for a HiDef capture card that would work with Linux and an external HD receiver. The pchdtv card looks nice but it's RF input only for HiDef content, and only supports OTA at this point. Both DirecTV and DishNetwork HD STBs can be hacked with FireWire ports, but it's not cheap, so I was trying to find a capture card with either DVI or Component inputs, or a converter to take either of those to FireWire. The old Dish Network model 5000 receivers had an option to output HDTV RF but they are no longer compatible with Dish's current HDTV broadcasts. Google has not been helpful in this regard, and all I've found is professional (>$2000US) format conversion gear. Is there a PC (hopefully Linux) based video capture solution that can capture the output of a cable of DBS STB (RGBA, DVI, or Component out) without a significant loss of image fidelity?"

Ballmer Threatens Linux Patent Lawsuits 506

gillbates writes "Today Microsoft warned several Asian countries that using Linux could subject them to lawsuits, claiming that Linux violates '228 patents'. Apparently, Steve Ballmer believes he can enforce U.S. law in Asia." Ballmer is presumably speaking about this story. So, companies which sell insurance against lawsuits and companies which make competing products both warn of the dangers of using Linux. Maybe someone should point out that Microsoft is battling dozens of patent-infringement lawsuits itself, and any user of Microsoft software (including governments) could also be sued?
