Yes, beta is really surprisingly horrible, and i really hope classic will remain an option.
<conspiracy>i bet the GNAA infiltrated dice, and made them create beta! (what have they been up to, anyhow?</conspiracy>
That being said, may I recommend some kind of diplomatic hybrid solution?
- make slashdot's CSS not suck, so that it is easily skin-able. Let US come up with funky themes in CSS form - and we can bet you that 'classic' will be one of the first ones to appear
- make slashdot more reddit-esque in the sense that everything should be API-accessible. That way, if you want to add some oh-so-great feature, you can just add an API call, an someone will mangle the CSS to reflect that. Hopefully, many new slashdot reader apps will pop up (including a decent mobile one! something like 'reddit is fun', but for slashdot!)
- you want to make more money? add that reddit 'give gold' option. They really seem to be making money of that over there, and it goes along nicely with the whole "karma" economy that slashdot basically started. I mean: you've got us all working for you, indirectly, because we all come here for the comments, which are made by us. So give us some additional way of cheering at each other for doing a good job, and make some money off of it!
- unicode! Hell - i make my living writing perl, and basic unicode is really not THAT hard. Geeez.
- if you want to make the whole place more modern and dynamic, you can always add bells & whistles like (unobstrusive) auto-updates and all that jazz. Hell, some CSS themes could even incorporate those obnoxious, but "modern" jQuery animations!

+ - How would WiFi look, if we could see it?

But I wondered how wifi would really look, if our eyes could see the relevant frequencies.
I would imagin that this should be possible to do, with a spectrum analyzer and an extremely directional antenna, that scans the viewport pixel by pixel, and assigns a color.
My guess is that most walls would be slightly opaque, whereas rough metal surfaces would be bright, and so on. Has anybody done this? Is this possible? Are there antennas that are THAT highly directional?"

Comment: Any experiences on Hybrid RAID-1? (Score 1) 172

What a coincidence! I am getting ready to transition our main DB servers (couple of GB mysql data) to SSD, but I simply dont want to trust it that much yet. So my plan is to set up RAID-1, with an SSD and another conventional drive. There seems to be this "--write-mostly" option that tells linux to preferably read from the SSD. Anybody know if this is worth it? If it works? What kind of random access performance gains can i look forward to, running mysql on SSD? I found it surprisingly hard to find any good data on these subjects.
DRM

+ - Office document 'DRM'?-> 1

schweini writes "Even though DRM is obviously 'evil', I have recently come across a good use for it: I work with a travel agency that manages a lot of semi-confidential office documents (internal price lists, etc.).
Everytime an employee decides to leave, the big question if (or how much) information he will steal from us.
Hence, the question popped up if there's an easy way to restrict the usage of office documents to our LAN. I figured that a feature like that must be so popular that it shouldn't really be a problem. After consulting with my good friend Google, the only thing I could find was Microsoft's "Information Rights Management" option, which surpisingly is very under-documented, IMHO.
To make things worse, we are using a Samba server, so all the fancy windows-based licensing options are not available for us.
My question to my fellow slashdotters is if anyone knows of a way to (as transparently as possible) implement some way of restriction/encryption that renders internal documents useless as soon as they leave the premises. For my case, it wouldn't even have to be bulletproof — even some embedded macro that asks our server for permission based on an IP address or something would be a lot better than no protection at all."

Here's Bill Gates' TED presentation on this project from almost 2 years ago:

Even if half of this design works out as advertised, i think this would be awesome! Pity that the 'western world' wasn't interested in investing in it and trying it out....

Living in Costa Rica, let me say that I really miss the 'classical' seasons. Here, we just have 6 months of dry time, followed by 6 months of rain in the afternoons. It's great for a couple of days, since the temperature is nice and cozy all year long, but it really does get boring after a while.
If I'd designed the climate here, I would've at least had the decency to switch between rain and dry every two weeks or so, to keep it interesting.

I agree, most of all with your first step, because IMHO, the others more or less follow naturally from critical thinking.
The problem is that all the conspiracy-nuts insist that they are the sole owners of - what THEY call - 'critical thinking'.
Why is there no obligatory class called 'critical thinking' in schools? Should be really easy to implement, and could easily made fun, i think.

Actually in Germany we (used to?) have a similar law: it is legal to drive with relatively low BAC, and if you get stopped by a routine control operation, that's fine. But if you get stopped because your were driving in a way that might seem "adventurous" (stuff lke running a yellow light, speeding, weird manouvers) with the same low BAC level, you'd get fined.

I just thought of an experiment:
Assuming your tinnitus is a near-constant frequency sine wave, what happens if you try to cancel the imaginary sound out using an external sound?
I have no idea whether it's even possible to try to sync soundwaves that exactly by hand/mind, but maybe you can hear/perceive some interference, at least?
I'm not saying that this could be a cure for tinnitus, but me, at least, would be fascinated if imaginary sounds can interfere and maybe even cancel out physical sounds...

On a related note: there used to be this nice open source skype-alternative (using SIP and all that) called openwengo, but i cant find it anymore. the company also offered a flash based SIP client (wengovisio), and a flash-based teleconferencing thing (wengomeetings), but i cant find any of them anymore. quite a pity.

a little side-rant: the person that designed the SIP protocol in such an incredibly NAT-unfriendly manner should be drawn and quartered. I know there are work-arounds, but i blame this NAT-unfriendliness for the rise of skype, and now we're stuck with that nonstandard closed protocol crap. I think it was the glorious idea of incorporating the IP addresses inside the SIP packets, or something like that. sigh.

on a related note: whatever happened to Google's open-source VoIP thingy that incorporated with XMPP/Jabber? I think it was called 'Jingle', but I haven't heard a lot about it since then. And what protocol is Google using for their video-chat in gmail?
