you would think so from the article, but reality so far has shown differently. I have already run into two instances where someone using the beta copy of winzip9 used the new format by accident and those people using pkware or xp's built in zip readers could not read the file because of some header issue or something like that. Once they rezipped the file with the winzip8 option (aparantly that's what they did as both posts said something to that effect) no one had a problem reading the file. I hope that whatever issue is causing this is removed before the release version.
Remember TI ships more chips each year than Frito Lay! Yeah they aren't as sexy or nearly as high margin as x86 cpu's but they are the little microcontrollers that make computers basically ubiquotous in our world.
Transcoding is never recommended as there are fundamental differences in the way that different encoders (even different implementations of the same format) will decide on what data is unneeded and so you will get more and more data thrown away in each step. There is no panacea in this regard so the only solutions are to reencode everything or rip to a lossless format in first place. More and more people I know are doing the latter so that they can encode to whatever codec happens to be popular this year.

AAC Put To The Test

Sorry but with the exception of really horrible examples like the xing encoder most lossy encoders sound fairly comparable at an equivilant bitdepth, and to my ears everything sounds shitty at 128kbps SBR. It doesn't matter how good the master is if you are throwing away that much accoustic information, you will lose low and high end fidelity and you will most likely get compression artifacts (some encoders do a good job of avoiding the artifacts even at fairly low bitrates). Also I HAVE heard a couple examples of the iTunes AAC files as a friend is a mac guy and he bought a couple of files, I put em on my iPod just to see what they sounded like with my iPod and Sennheisers, I could definitly tell they were fairly low bitrate samples, though probably about equivilant quality to a LAME 128k VBR.
What you prefer the loss of the pits on your LP wearing as the needle passes through the grooves? Yeah spectral analysis shows that after three plays with a high end player the LP has already lost MORE dynamic range then a ADAT recording, and of course in hundreds of plays and a couple generations the digital copy is obviously superior, plus getting vinyl from mail order sucks, I know I DJ and the % of DOA stuff is way too high for my liking (especially if it's a white label or rare import, ususally means I get the insurance $ but never find the music again for a reasonable price). Analog has its place (like scratching, cd's just are not the same) but long term quality is not where it's at.

Well it matters because some people are buying shitty 128k aac file from Apple (a LOT aparantly, they have sold almost 4 million tracks already). I too rip to high quality mp3 (~220kbps VBR mp3's from LAME which passed tripple blind with wav and ogg) but I guess it's usefull to know what quality you can expect from this service since Apple will be coming out with iTunes for windows later this year and bringing their online service to the masses.
Except to the public libraries like mine which have the fortitude to tell the federal government to shove their money up their right wing ass along with their content filters. The fact that the federal government takes my money and then attaches all sorts of political criteria to it before returning it to the state and local level pisses me off. It's like the federal highway funds, the pissants in Washington forced the state to lower the speed limit to 55 even though no one in the west was ever going to drive that slow, it would take forever and serve no usefull purpose, or the raising of the drinking age to 21, or the lowering of the BAC limit to.08, now my cousin can be arrested and have her liscense revoked after 2 stiff drinks. Sorry that was a bit long of a rant to make the point that the federal government will always take as much money as we allow them to and doll it back to us based on criteria set by minute special interests.
buy Cisco cards, they cost a bit more but they will have drivers for their 11a and 11g stuff eventually and already have it for their 11b cards. They have a person dedicated to linux development including drivers and support software for their LEAP secure authentication system.
Chances are you have metal mesh backed plaster or plasterboard. This is common in some parts of the country and acts as a faraday cage. btw the numbers listed are always in an open space such as a cubicle farm devoid of cubicle walls, no manufacturer will make claims about any other environment. Also the airport has configuration programs written in java and native version for linux and windows as well so unlike what the author claims you do not need a mac to configure it.
I know this is meant as funny, but even with a 24Db 4 foot dish antenna you still can't feel the energy from a 11b radio, it's still under 8 watts or about the same a a high power CB (5 watt max), and about 100X weaker then even a cheap microwave.
Soon there will be no pringles. The only pringles plant in North America was almost leveled by a tornado earlier this year and so far they have not finished repairs.
newsflash, you don't have to live in the sticks to get decent rent. I live in a major suburb in the 10th largest metroplex in the country and I only pay $550/month for 1150 sq ft 2 bedroom apt. Not everywhere has crazy pricing like LA and NY.
No, and if Peoplesoft has anything to do with it they won't be. Oracle has launched a hostile takeover action that based on todays closing price will fail. Some people speculated that Oracle would discontinue peoplesofts products and use the aquisition as a customer list, but I can't see that happening because the now screwed customers would have very little incentive to go to the vendor that just screwed them out of a multimillion dollar investment.
If not from redhat then from third party vendors. I think that eventually people like Oracle, Peoplesoft, etc are going to support their software on RH AS exclusivly because they won't have to come out with a new version every couple of months but will instead have to follow the 3-4 current versions of AS. If you don't think you will need this kind of third party support, or will only need it for some of your servers then maybe split your shop, RH AS for those platforms that need to be more stable and less of moving targets, and the standard distro for webservers, whatever that can afford to be broken once in a while because it's tracking the bleeding edge.
LVM snapshotting is whole volume and has additional problems, like if you run out of space in the new temporary location for the live system all updates since the snapshot are lost. NetApp's snapshots are so powerfull because you can have multiple levels of them (we used to use hourly going back 12 hours to cover the whole business day + leniency for early/late worker, daily going back a week, weekly taken every friday, and monthly taken mid month.) and other than potentially running out of filesystem space they had no impact on the live filesystem. From what I've seen there was an attempt at true netapp style snapshotting on linux called snapfs, but it has been dumped and the project basically pulled from sourceforge. There is also a commercial product out there that uses some limited form of snapshotting to turn any x86 pc into a linux based appliance, but it supports a max of 8 snapshots and runs $1100.
why I feed the trolls I don't know, but all decent volume managers allow you to resize partitions on the fly so you can add storage capacity as demand dictates and assign it to the areas that are actually growing rather then those which you think will need the space when you initially setup your partition scheme. This is a feature found in most commercial Unix variants as well as big iron, and is found in one way extensions in win2k and above.
As a leading expert on linux filesystems I was wondering whether you were aware of any snapshot implementations for linux similar to those found in Network Appliance filers. Since working in a shop that used Netapp's I have always found myself wishing for the admin time saving feature of snapshots without the high cost of a filer. Veritas's snapshoting is whole volume only as are the other solutions I have seen outside of Netapp, is this a technical hurdle that no one else has been able to jump or is it a patent issue? Thanks for your time.
My credentials are that I was the linux expert on the deskside support team that supports Cisco Systems. When Cisco decided to go with Exchange for internal reasons we started looking for a good linux solution. We needed to support not just email, but calandering as well because all calandering was thankfully being moved off of their previous "solution" (it sucked equally on all platforms). We could not use POP3 for email because it broke the model of some of the backend software that was being grafted around Exchange so it was either IMAP or MAPI, and when you add in the need for calendering support the only viable solution was Ximian connector+Evolution. Setting the default save option to MS formats makes sense in a mixed environment because then the user does not have to think about resaving the document before sending it to a collegue. Btw, this was for a couple thousand seats of linux desktops in a mixed Solaris/Win2k/RH environment.
All 3 of the graphics programs I use routinely creat PNG's that are larger than gif's, now this may not be a problem with the format persee, but it is a problem with the real world implementations that are out there and are being used. It doesn't matter for a hill of beans how cool a format is on paper if the implementations suck, if the graphics programs are creating bloated PNG's and the large leader in the web browser space renders them incorrectly it is unlikely that there will be a rush to adopt the format. Like I said I understand that it is a superior format for some things but for most people there just isn't much incentive to switch.
large file size- much larger than gif or jpg poor standardization- alpha in particular is different accross platforms and browsers (IE is the worst offender here) little exposure- even my grandma has heard of jpg but few people including "web developers" have heard of PNG, even after years of existance.
That said if you have to mix text and graphics PNG is the way to go as it will not trash the picture like gif and won't pooch the text like jpg.
Trust me they are used pretty widely in the corporate linux market. Red carpet is a great rollout manager and Evolution is THE email client to use under linux if you have to talk to Exchange (requires Ximian connector which is not free software, but it truely rocks).
Second largest independant, if IBM broke out their software devision Oracle would be #3. They make a bunch on the apps because not only do the apps bring revenue and consulting dollars but they are basically always deployed on Oracle databases which is of course where the big money is.
With the low power and close proximity that RFID tags work at just about any metal lining would work, no lead needed. Cheap aluminium might not work if they use real powerfull detectors but baking strength or copper foil should.

If you are close enough to read an RFID tag you are close enough to detect the gun with a metal detector. Much harder to disable =)
