If you mean registration passwords, we made a custom register form where a user fills it in and a confirmation email is sent to all admins, it's their job to contact the person that filled in the form to make sure it's legit and click on the confirmation link in the email - no one but the person registering knows the password and they use the same form to change passwords.
If you mean sharing servers passwords and what not, we store public PGP keys on the wiki and any passwords sent are sent by email encrypted with PGP.
I don't think you understand. 80% of UK ISPs blindly throttle bittorrent by protocol header to 20KB/sec or bellow, so you cannot change the port number or make sure your firewall is configured correctly or anything else. Without RC4 encryption there is no hope of getting speeds better than a fifth of the provided bandwidth or bellow, even on the new 8mbps expensive contracts.
Yes, you're right, but what do you use instead? - What else supports encryption (absolutely must for most UK users these days to avoid throttling) and allows you to prioritize files in a collection? And has all those other useful features like decentralised source sharing, etc?
I'd be careful if I were you:) - I upgraded from the Shure E2c on some horrible sounding sony minidisc to the E3c with a flash player, then Senn HD580 on an envy24ht sound card. it all got pretty blurry but now I have a Cowon A2 and Shure E5;)
What kind of crap is this, lol? -- If you think 320kbps is audiably inferior to ATRAC invest in an $80 Rio Karma with lossless FLAC support - I use it with my Shure E5 headphones ($500) and it sounds absolutely incredible without the horrible static and hiss I hear on minidisk players.
My friend has a Palm T3 and another friend has a Sony PDA and a Zaurus PDA and a mobile with mp3. The sound quality on all of them is plain and simple unbearable!
With $15 headphones, you notice either a complete absense of bass or boomy uncontrolled bass, the mids sound like behind a foot of concrete and the highs are shrill. And my friends are *not* audiophiles or care about quality and encode with 64 and 128kbps. They are just your regular people that happen to own an ipod and comparing it to a PDA or phone, its the difference between unbearable vs pleasant.
Personally, I find even the ipod on its own unbearable and have the Cowon A2 PMP with the Shure E5 headphones, but hey there has to be a limit for when a consumer becomes lower quality than tolerable and phone/pda as a music player is it.
1) I'm using a Gigabyte nforce4 ultra motherboard (the passively cooled one) with 8 onboard sata controllers and another cheap over the counter 4 port sata pci card for a total of 12 drives. 2) I made a mistake here by using all of the same drives bought from 1 place - I only read the horror stories after:( - It seems very possible for multiple drives to fail within 20 minutes of eachother after 8 months (!!!) if they have consecutive serial numbers and part of a bad batch. Dont make this mistake! - Since I couldnt return the drives, I made another raid1 array with different drives for critical storage and OS, the raid6 is mostly media backup and recording shows. 3) I use software raid. SCSI hardware raid is far too expensive and the performance of software raid is generally better than those onboard raid controllers. I also like having the ability to resize the array (although not tried it yet) and I just trust it more. I've been using software raid for half a decade now and it withstood all of my abuse so far while I saw expensive scsi raids fail from simple things like rebooting while the array is rebuilding. 4) Another stupid mistake here, I'm using reiser4 and its caused problems for me already. No data loss, but just try using it with a berkleydb database or anything like that and watch the kernel panic:) - I also had reiser4 corrupt partitions at work on development boxes (no data loss, but unexpected behaviour and reboots required), there is also other strange dmesg errors for reiser4 and if for example you umount a reiser4 partition and mkfs.ext3 over it, it just refuses to work, you have to reboot. I wouldnt recommend reiser4 for now! 5) I have an ANTEC PSU/Phantom 500 GB 500W ATX12V v2.01 PSU. To be honest I havent hooked up the failsafe PSU yet but its an option on the coolermaster stacker I'm hoping to use soon. I havent had any problems yet, but I guess it does strain the PSU when the drives wake up and the PSU fan does turn on for a while when drives spin up. Looking at the data sheet, it seems the drives do spin up at 30W even though operating peak is only 12.3W (7W idle) and my system is otherwise like the one tested here: http://techreport.com/onearticle.x/7417.
The PSU is 85% efficient so I guess 510W is quite a bit over the realistic maximum of 420W, but the system is not only idle most of the time but the CPU auto throttles to 1GHZ almost all of the time, so while I havent measured this, I bet the idle consumption of the system is closer to 90W which means 330W available for the drives. Now that I think of it, I probably need more power, lol. 6) Only issue is slow wake up time. It takes around 15-30 seconds before I get a file listing. 7) Cooling tips, well, fanless motherboard, fanless (for the most part) PSU means less worry about fans:) - I have 3x120mm 20db fans drawing air in and cooling hard drives on the way, 1x120mm 25db fan sucking air out the back, 1x25db fun sucking air out on the top and the cpu cooling is the Zalman CNPS9500 (the huge vertical cooler) that also helps with the airflow. I also have dust filters on all intake (included with coolermaster stacker).
As for silence, at night it is no way near silent.. but in a good way:) - What I mean by that is there is no whine or noticeable noise, instead there is a very low tone hum. If you walk past the PC at night you may not notice it is switched on until you switch it off - its basically like the sound of the ocean from a far, you dont want to turn it off:) - Then again we are in the countryside so chances are it will be plain inaudiable for most in the city.
I have a Coolermaster stacker with 12x500GB drives on raid6 - thats 5TB of storage with 2 redundant drives siting under a 36" LCD in a cabinet - (you know, so its inaudiable).
Sure the drives alone eat around 200W of electricity, but I have another raid1 array of 2 x 2.5" drives I have the OS and basic storage on, the raid5 spins up only when I want to watch stored content (since the whole family uses it, its something like 5 hours a day, but its not showing on the electricity bill).
Now the juicy part, the system is used for: 1) Phone, we have a normal analog line plugged into the PC and a voip contract, if we phone out, it goes over the internet saving a ton of money, incoming calls go through the PC so if no one is there, voicemail is emailed out or a fallback number is used like a work number that is forwarded to through voip (using asterisk@home, very easy setup). 2) Watching/recording sattelite TV, a simple DVB card plugged into a dish - didnt bother getting decoder cards or subscribing to Sky and what not as >1000 channels is really enough;) 3) Surfing the web 4) Playing games on/offline (kick ass for FPS) 5) Listening to music with visualization 6) etc, etc, etc.
The remote is a cheap ATI one that works with Linux (using ubuntu dapper with XGL, looks stunning) and I have a media keyboard/mouse in the coctail table for FPS and what not.
I had to build it myself of course and set it all up, but it only took a day's worth and it was damn well worth it! - Any hardware problems I am emailed about instantly, there is a redundant PSU, redundant drives. Only had it for a month so cant speak of reliability, but I cant see it being any less reliabe than just a DVD player while providing so much more.
What are you talking about? - XEN is/*virtualization/*, sure its more than an advanced chroot, but it lacks security because there is no real isolation from the underlaying kernel and it requires you to jump through hoops to get going (ok, nice that Redhat bundle it, true).
UML on the other hand is/*emulation/* -- its like comparing wine to vmware. Apples to Oranges.
UML has far superior isolation from the underlaying kernel, it runs entirely in userspace so no jumping through hoops, and it is the same speed as XEN for CPU bound applications like number crunching (although much slower for I/O bound applications).
So each has major advantages/disadvantages but for a mission critical server, I would choose UML every time.
1) Use a free gmail account and back work onto there? - its as easy as using a floppy on windows and you can even have gmail show up as a drive on your desktop!
2) You can take any desktop, create a shared drive on it, and everyone can select it from a list. You can also set up an FTP server (its much easier than it sounds) to let people access the data as what looks like a drive from home.
3) Use flash drives, a 128MB flash drive costs as much as a pack of floppies (and I'm sure you get through a lot of floppy packs, we did - they are so damn fragile) and has almost a factor of 100 more storage. I know many schools that charge parents those small fees to get the flash drives as an optional but recommended extra.
Polish can come after the release. Personally, I couldnt wait and upgraded to dapper drake because of XGL and Compiz (the 3d desktop) - Boy I'm glad I did, so much have been fixed and improved, it fixed all my video playback problems, the startup times are infinitely lower, far better hardware support (wireless anyone!?), etc.
Why do I appose to delaying the release? - Because the only reason my less technical friends didnt upgrade is because, ah, hell, a couple of weeks more now and its ready, now they will and probably ruin their experience with the rash of pushing packages into an unstable branch, shame:(

Mind telling us what Outlook does that Evolution doesnt?
Only thing I can think of is the downright awful Salesforce integration that allows you to click on a link to see the web interface and slow down Outlook.
Other things are poor stability, poor performance, 2GB pst storage limit, painfully slow startup with more than several thousand emails, decay from normal use requiring periodic installation, etc.
Yes, I agree with you 100% - Robbins is a fantastic project manager, gentoo to this day has bar none the best documentation of any opensource project I've seen and to get a Linux distribution off the ground like that with over 100 competing, Robbins is a great man.
I was responding to the comments of "he must be such a sharp coder", his code is quite possibly the worst python code I've ever seen, hacking portage was just painful.
Portage is proof of this. Have you seen how bad the code is? - You cannot tell where the backend stops and where the frontend begins.
Try to import portage and see how far you get? -- the emerge frontend does *everything*, portage is just a couple IO functions easier achieved with cat.
If Robbins feels he wasnt used to his full potential in Microsoft, then, hmm, nice to know the "real world" is much easier than all us students expect;)
CMS is a Content Management System liks PHPnuke or Plone, or Tikiwiki. In laymen's terms it is basically a dynamic webpage that can be setup from scratch in minutes that multiple people can manipulate.
I mostly agree with what you say, but I cant help but remember the "Free Hat" South Park episode:
- Just tell us this Tweak, what do you see positive about todler murder? - hmmm, its easy? - ah, you're right, it is easy! - now onto your other cause...:)
Yes, I get around 10% cpu use for xvid on a transmeta crusoe 866mhz (about as fast as a 400mhz P3) -- how on earth did they manage to get 30% utlization on a 3500+ AMD64!? - thats insane!
My question is there are currently 23 security exploits in windows xp that you have known about for many months and they are well documented on sites like secunia.com and securityfocus.com. With Microsoft's unlimited resources and focus on security, why arent they getting fixed?
Err, what about when will you stop promising great security 8 months down the line and show us a working product? - We are tired of hearing the same crap we heard back in 1998 and 1999 and 2000 and 2001 and 2002, etc about how the next version will be the one to fix security faults.
khtml is the kpart konqueror uses to browse. It can even be replaced with the gecko engine from mozilla. Konqueror is just a wrapper to be able to browse directories, cvs, svn, view multimedia, etc.
