  3. Re:Only slightly OT on FreeBSD Documentation: An Interview with Tom Rhodes · · Score: 4, Interesting

    I usually upgrade from source. You don't need the current sources to upgrade, just the new ones, so grab them with cvsup.

    I do the initial builds offsite and usually well in advance (perhaps leave them to work on a Friday evening).

    1. make buildworld
    2. make buildkernel

    Once onsite, I:
    3. make installkernel - takes a few minutes, doesn't count towards downtime.
    4. reboot
    5. mergemaster -p - takes about a minute
    6. make installworld - takes maybe 5 minutes at most
    7. mergemaster - this takes the longest - I usually manage it in about ten minutes, as I've become pretty familiar with it, and make the right decision pretty instantly.
    8. reboot

    I've timed myself, and I end up with 15-20 minutes downtime, depending mostly on the speed of the machine.

    Going more off-topic, but I had an idea on how to make this process faster, and to make mergemaster much less scary.

    Most of the files that are affected by the mergemaster process are rarely actually changed. On a stock server, you'll probably only ever change files in /etc/mail, /etc/namedb, /etc/ssh, and perhaps one or two other file. All the rest of the files are usually unchanged by the sysadmin. The mergemaster process however asks you if you want to upgrade all the files that have changed in CVS. This takes a lot of time and involves repeating the same keystrokes, and is probably the source of most accidents: shift-G, i, shift-G, i, shift-G, i, "oops, shouldn't have overwritten that one!"

    It should be trivial to, pre-upgrade, traverse /etc, extract the version numbers, download their originals from CVS, diff the two, and build an "auto-list" of files which have never been altered.

    When mergemaster is run, it can then automagically upgrade all of the files in the auto-list; if nobody saw fit to change /etc/mtree/BSD.usr.dist, chances are the new one will do just fine. Meanwhile, the sysadmin only has to think about that matter to him.

    Also, prior to doing the upgrade, he would be able to get a list of files which he *has* changed, so he can figure out what exactly he was thinking when he decided to hack /etc/rc.d/initdiskless to bits.

    Any reason this wouldn't/shouldn't work? Obviously mergemaster should give Big Bloody Warnings before using the list. I reckon I'd save at least 25% of my downtime doing this.

    It would appear they are not interested in marketing this directly, but through other companies. On the site they highlight the large recessed area on the back suitable for a sponsor's logo, and I couldn't find any price information either (site slow, maybe it *is* there).

    "what are they called, CCV2 or something"
    For the record, I looked this up when doing a shopping system once.

    Visa uses the term Card Verification Value (CVV2), Mastercard calls it Card Verification Code (CVC2). I don't know what the "2" refers to, one assumes there was once a CVV and CVC. Some websites claim the initial "C" in both stands for "Credit Card", but the system is used for debit cards too, so it appears the authors in question were being stupid.

    Amex has a Card Identification (CID) which is a four digit number that appears on the front of the card.

    It annoys me when I see online forms providing options of Visa, Mastercard, and Amex, and then ask exclusively for the CVV2. Almost as much as the sites that insist I tell them what city I live in, ignoring the 50 odd percent of people who don't live in one.

    The term Card Security Code (CSC) is used as a catch-all label, and it's what I use when building shop sites.

  20. Re:WAR! on Hotmail Means to Double Gmail Storage · · Score: 4, Interesting
    Gmail is a *huge* improvement over Hotmail on the user interface level.
    I beg to differ. Gmail's UI is geared towards low volumes of email. If, like me, you receive thousands of emails a week, a number of major problems rear their heads.
    1. There is no way to distinguish similarily named mailing lists. You can only filter based on "To, "From", and "Subject" headers. Let's examine the options:
      • To: Useless, as people will Cc a list, or the email will be sent to a smaller list which is then redistributed to the larger list. Bugtraq is an example of this.
      • From: Some lists set the "From" header to their own address, others leave it unaltered. In the latter case, the "From" header is useless, unless you happen to have a full subscriber list. Even if you do, you're screwed if somebody is subscribed to two different lists that you are on.
      • Subject: This usually works for lists that insert the list name into the subject. However, there are exceptions. I'm subscribed to the DBMail users list which inserts "[dbmail]" into the subject. I also receive bounce notifications from my mailer daemon which includes "DBMail" in the subject. If I set a filter to match "[dbmail]" in the subject, it ignores the square brackets and so tags the bounced messages as well. It also tags emails on the dbmail-dev list.
      By applying multiple labels I have it working after a fashion. It took way too much time however for such a simple task.
    2. New filters cannot be applied retroactively. If you receive a few hundred emails that need classifying and come up with a filter for them, you then have to manually apply it to the older messages. I still have about 8,000 unclassified emails because they came in before I created filters for them.
    3. Their address book is terrible, and there isn't any way to import an existing one.
    4. There's many more problems, including their stupid lack of a plain HTML version. That one I could understand if they were rushing to a launch date and wanted a feature-rich, IE only version out the door. They do not seem hurried at all though, so they really should have started with a simple standards compliant version and then added the per-browser bells and whistles. I have to go do some work however, so I'll end my rant shortly.

    I know and understand Gmail is in beta. I have reported all the problems I have had months ago. None have been fixed. However, the very fact that you cannot search by a user-defined header baffles me. I can only assume they index the messages by to, from, and subject, and don't cache the rest of the headers in a usable form.

    Shrug. In the end of the day, I don't particularily care, I'll continue using Sylpheed-Claws which copes extremely well. I would have like a web-based backup though for when I'm not near my laptop. I guess I'll have to finish writing my own.
