  1. Re:Finally Fedora? on First Look At Fedora 11 Beta Release · · Score: 1

    I successfully upgraded a server from RH 4.2 to 5.1 long ago, and while it did have a few buglets, for the most part it worked.

    I personally find that if you are changing from one major release to another major release you are normally better off doing a fresh install and recovery of data. For minor releases upgrades or updates are fine. Of course if you are doing this for a customer you sometimes don't have this luxury and if something goes wrong the customer is not very happy. I have seen major upgrades fail with enormous amount of time wasted escalating to customer support and them coming back to you with the recommendation that a fresh install and recovery is the best way forward. A definite case of "I told you so".

    When I mentioned recovery of data, this could be tape/disk backup and recovery (could be many hours) or just a local volume manager recovery (minutes). BTW I am not just talking about Linux distributions I am talking about Unix distributions as well. Homework is essential before doing anything especially when you are doing an upgrade for a customer.

  2. Re:Finally Fedora? on First Look At Fedora 11 Beta Release · · Score: 1
    I originally started with Fedora 7 and have progressively updated over time to Fedora 10 and my experience has been very positive with all the distributions. There have been some glitches most notably KDE 4 (it's fine now) that came with Fedora 10 but then again you should expect this with Fedora.

    Actually one of the packages that does get a mention in the article and no one here has commented on is "Presto" which utilises delta rpm's instead of whole packages to update the distribution. To the novice this does not mean all that much but if you have limited download capability (most of the world) then "Presto" is a huge improvement since what could be a 100MB or even 500MB package update, with delta rpm's the all over download could be anything from 50% (normally worst case) to 1% of the total package size. When I first put "Presto" on Fedora 10 with a "yum install presto" command it did not work since there wasn't any delta rpm's for Fedora 10. Now there is and it is impressive how much I save in downloading.

    It must be noted that utilising delta rpm's is not really new since SuSE, Debian (delta packages) and even Redhat have been using them for a while now, however in the case of Fedora you always had to download the package and even then if you did not have an older version of Fedora the delta rpm repositories did not exist. This time with Fedora 11 "Presto" is installed by default.

    I haven't had the nerve to try 10, though I've heard good things about it. Once bitten, twice shy, and all that.

    Like any Linux/Unix upgrade, rebuild you always need to backup your original OS and data although you should be doing this already. Once you have a recoverable backup you have the option of doing an upgrade or a fresh install and possible data recovery. Personally I prefer a fresh install and recover my data but that's me. When I move to Fedora 11 (normally within a month of release) it takes me approx 5 hours, four of which is backup and recovery and most of the time I don't have much to do.

    The above is a methodology I normally apply when I consult with customers. My attitude is once you decide you are going to upgrade or rebuild (preferred) there is no going back, although to keep the customer happy I can always recover if appropriate and still charge accordingly. Of course you have to do your homework first such as determining if the applications the customer has will work with the upgrade. If the applications don't work the vendor should advise on this and the proposed OS upgrade postponed until the vendor provides an application that will work.

    One of the reasons why I like a fresh install over an upgrade is the fact that you are starting fresh and are not carrying over possible issues. This does take longer but IMHO it is worth it.

    I wish TomTom had fought this; the FAT patents are utter nonsense. But patent fights are notoriously expensive, so I understand why TomTom did this instead. In the long term, I hope that software patents get eliminated, but that will have to wait for another day.

    Could not agree more, however the only way to get arround this would be to use a file-system like ext2 or ext3 which is very easy to do from a Linux machine onto an SD, MS, XD, MMC or any USB storage device. The problem here is not using ext2 or ext3 it is the ability of the Microsoft OS to actually read the device since Microsoft won't support this file-system preferring to dictate what file-systems they support with their OS. Coupled with this is the fact that many devices (eg. cameras) that take cards or even USB storage devices also cannot read ext2/3 file-systems.

    To get a file-system like say ext2/3 supported would require a courageous effort on the part of manufacturers to demand this type of support and I personally don't think that will happen any time soon.

    What is bizarre is the fact that it is very easy to create a FAT32 file-system on just about any Linux platform yet you actually have to download software to a MS Windows (Win2000 on) machine to do this. This reinforces my impression that Microsoft expects everyone to do as they dictate and they don't even care about FAT32 except as a means of using it as a bargaining chip.

    When I installed Fedora 10 it came with KDE 4.0 and that was a shock. For my wife the change was too radical and I quickly switched her to Gnome. I knew KDE would improve over time however what forced me to change to Gnome was the fact that switching users was impossible at the time. For a while Gnome worked quite well but I wasn't that happy with it since it always felt "old school" but usuable, however KDE at the time was painful to use.

If this is the case then for the Linux user assuming you could download the game you would have to use a MS Windows emulator such as Wine.

Some people do some people don't.

    Basically like it or not Microsoft really commands the game market on PC's although it never ceases to amaze me that there are many millions of Linux users in the world and most likely as many as some of the consoles on the market today and yet these consoles have hundreds of games available for them. To me it seems that most PC games developers don't seem to care for the millions of Linux users which does actually translate to lost sales. If a company was brave enough to make native games for Linux they could also make a good deal of money as well. Of course they could loose as well but that is the chance you take and this equally applies to MS Windows and console games as well. If consoles are anything to go by then one to five million game sales (depends on the game) can actually make a profit and there are enough Linux users in the world to support this.

    At the moment there does not appear to be many innovative game developers, most are quite happy to bring out instalments 2, 3, 4, 5 etc of a so called franchise. You know who I am talking about. I know this type of approach makes money and in some respects I can't blame the developer since they are in the business of making money so in many respects it is the buyers fault for being happy with this. Some franchises can be well worth waiting for but many are really just an add on and an incremental add on at that still it appears many people like this.

    Finishing my console rant, my attitude to Linux gaming is if a game company can't make a native Linux game then they have just lost a possible customer. The loss of one customer is nothing and why should any company care, but millions? IMHO these companies are either drinking the Microsoft cool-aid or they are being subtlety threatened.

    Patent Trolls usually start off attacking a company that is small and since the company can't afford any long drawn out litigation it pays what to them is affordable amount of money to make the Troll go away. This is great from the Troll's perspective so they go after more higher profile companies with a now much stronger patent always being careful not to attack those who can fight until they have strengthened their patent before the law.

    Nasty but that's how the law can be made to work for the Troll. Fortunately this case was given the boot but I would not be surprised if the Troll bounced back with a slightly stronger patent and the fun continues again. In the long term it is the consumer who pays for this ridicules pantomime.

    There is genuine patent litigation, however it only takes a few Troll's to bring the whole patent system into disrepute. Of course it does not help when you have countries that recognise software patents which IMHO are really patenting mathematical constructs and some simple electronic circuits that any second year University student would find obvious but that is an argument for another day.

    The choice of a sound systems is personal which can be a big issue within a family and between friends, especially if the one who is making the purchase has poorer hearing. To cater for everyone in a family a reasonable sound system is well worth the money but you need everyone to listen and agree to it first.
