Submission + - Linux installfests maturing? (blogspot.com)

christian.einfeldt writes: "Linux installfests apparently are expanding from an emphasis on serving individual users to mass network installs serving non-profits and schools. In the past, installfests have often been held as part of Linux User Group meetings, and involved individual new computer users bringing their computers to a small meeting to have Linux installed on their machines. But now there is an apparent trend visible in Linux installfests toward mass network installs supported by greater corporate or municipal involvement in Linux installfests. In many cases, the newly-installed Linux computers are being given to end user institutions such as schools. For example, a recent installfest in Austin, Texas, was put on by two non-profits and was supported by the personal participation of upper management at AMD and nFusion. The majority of the eighty-three machines were PXE-booted and mass-installed at that event over an ad hoc network. Likewise, at last year's LinuxWorld expo in San Francisco, 350 Linux computers were mass-installed over a similar PXE network in a mass installfest put on in a partnership between the non-profit Alameda County Computer Resource Center and the for-profit Untangle and IDG firms. The machines were donated to San Francisco Bay Area schools. Similar installfests have been held in Chile and India, to name just a few."

Bjorn Lynne.

He's one of my favourites - he's an accomplished artist with songs and online sales and he also runs a music licensing business with, IMHO, fair terms for the artists.

He didn't pay me anything to promote him just then. Internet advertising isn't always expensive.

I'm not even going to bother to offer a link to his site, but I'll bet dollars to donuts he makes money off this post.

Three Mobile Prepaid Broadband in Australia does this.

Upon connecting, a prepaid user gets an RFC1918 address. All TCP traffic is NAT'ed. All DNS requests are not NAT'ed, they are proxied through three's caching nameserver.

The problem with that is it causes hell for any caching nameserver at the client end. The client's nameserver expects to talk to the authoritative nameservers for whatever domain it looks up. It sends requests with the RD (Recursion Desired) bit cleared, because an authoritative nameserver does not need to use recursion to look up a name.

Three's proxy nameserver sees the cleared RD bit and, if the requested data is not already in the cache, returns an NXDOMAIN error to the client. It makes the client unable to resolve most domain names.

I hope the trial covers all of Scientology's scam - the impossible claims, the hard sell tactics, the cult attention, the brainwashing, addiction, their ruthless behaviour toward their enemies, the blackmail and infiltration ... this is an evil organisation.

Fortunately I am completely invisible to them because all they see on their screens is "elron****".

Wine

Wine Project Frustration and Forking 470

Elektroschock writes "Wine attempts to implement the Windows API layer on Linux. There are some limitations and an important one is the missing DIB engine, bug 421. Chris Howe comprehends the dissatisfaction of core developers with the arbitrary project governance: 'Sorry to sound like a stuck record but the Wine website still lists "write a DIB engine" as a requirement, and every time someone does, the patches disappear down a hole because they're "not right." Someone document what "would be right," or take "write a DIB engine" off the list. I'd love to have a go at documenting it myself, but I don't have the time to reverse engineer it from a few years' worth of rejected solutions.' The latest attempt of Massimo Del Fedel satisfied all requirements set previously for the long standing bug 421, and his optional engine seems to work fine by all Wine quality standards. He seems to be extraordinary stubborn and insusceptible to mobbing. Usually it is extremely frustrating for developers when the goalpost is constantly moved. When is the right time for project members to fork when their chief maintainer does not respond anymore or pursues an adverse commercial agenda?"

It sounds like they're not keen to spend time recovering it - although a lot of the site could presumably be recovered from google and archive.org and users' computers (particularly downloadable files).

I can't say I'm surprised, really. They couldn't be arsed to spend a little time to make multiple backups and now they can't be arsed to spend a lot of time to recover the deleted data.

No, the data was safe against only disk failure on the primary machine. Any number of different problems could have wiped out both copies including but not limited to data corruption or operator error.

I don't know if the two servers were physically close to each other but if they were then there are additional risks including electrical problems, theft and physical destruction.

Actually you use rdiff-backup for that kind of thing. It uses the rsync algorithm, but stores additional metadata to allow recovery of the filesystem state from previous backups as well as the latest backup.

If you just want the latest back you can restore with plain old rsync but if you want a previous backup you can use the appropriate rdiff-backup option.
