Could you please reference some sources for these problems?
I run half a dozen AMD64 boxes and I've had minimal problems running the following threaded APPS:
apache-worker-2.0.54 perl-threaded-5.8.6_2 (Just disable the port warning) php5-5.0.4_2
Along with all perl modules compiled with thread support.
I've seen no stability issues.
I find it interesting that you mention using the AMD64 FreeBSD, yet say you're running it on EM64T. I was not aware that EM64T is actually considered to be an equivalent implementation of the 64bit code. Therein may lie your issue.
Although ULE may be 'more' fixed in FreeBSD 5.4, I still find it to be very unstable. I'm unable to have a system booted for more than a few minutes before it kernel panics. (I'm also ironically unable to recompile a GENERIC kernel all the way through).
I eagerly await the next version of FreeBSD, in hopes that ULE is mature enough to take advantage of the performances increases of this more modern Scheduler.
This may however prove to be a moot point in light of the recent P4 HTT insecurities that have been revealed.
FreeBSD 5.4 64bit Support for Linux 32 Binaries

FreeBSD 5.4 Review

· Score: 4, Informative
I find the following comments from the article to be not accurate:
I was disappointed to find that Linux binary compatibility was still 64-bit only for 64-bit FreeBSD. That means no 32-bit Linux binaries.
Here's what you need to do:
reference/usr/src/tools/lib32 which will tell you to:
add "WITH_LIB32= yes #This makes buildworld compile lib32 linux code support" to/etc/make.conf
buildworld/installworkd in/usr/src
be sure the following options are in your kernel config:
options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!]
options COMPAT_IA32 # Compatible with i386 binaries
options COMPAT_FREEBSD4 # Compatible with FreeBSD4
options COMPAT_LINUX32 # Compatible with i386 linux binaries
# Linux 32-bit ABI support
options LINPROCFS # Cannot be a module yet.
Recompile kernel, install kernel, reboot.
Certain programs may require you add:
linprocfs/usr/compat/linux/proc linprocfs rw 0 0
to/etc/fstab
I didn't realize there were such relevant generic troll texts out there -- I normally ignore, but it was an early post that seemed to have atleat semi relevant content, and although my initial thought was 'wtf does this have to do with google', I got involved in the semantics of text's ideas.
And no -- I didn't purchase this account on ebay (nor was I even aware they were sold on ebay) -- I'm just an old-school slashdot user.
If your domain is high-jacked due to a fault with the security of your domain registrar, then yes, you have bigger problems than any anti-spam solution.
This is not the purpose of SPF
If you read spf.pobox.com You can learn that SPF is merely designed to be a system which can eliminate domains being spoofed in the from field of spam messages.
If someone is using one of my domains (logicx.net) to send spam; I can reduce the affect of such a joe-job attack by having a published SPF record; such that receiving systems can verify if the email came from a logicx.net mail server, and reject it appropriately.
SPF and PGP have entirely different authentication approaches. I'd go so far as to say that PGP is more integrity checking.
SPF is a verification that mail for a particular domain came from an appropriate server -- with the goal of disposing false emails (spam, spoofs, etc.)
This is not at all a system to verify users on that particular email system.
This is where PGP steps in -- It is used to verify the integrity of the email -- that it came from a particular user, and came unaltered.
Finally, where has it been verified that their was a breach of their DNS system?
All of the screenshots have now been confirmed to be a firefox situation where when DNS failed it resolved www.google.com.net -- which resolved to the people who own com.net
Although I question my usage based on what I read at dictionary.com under 'ironic':
"Usage Note: The words ironic, irony, and ironically are sometimes used of events and circumstances that might better be described as simply "coincidental" or "improbable," in that they suggest no particular lessons about human vanity or folly. Thus 78 percent of the Usage Panel rejects the use of ironically in the sentence In 1969 Susie moved from Ithaca to California where she met her husband-to-be, who, ironically, also came from upstate New York. Some Panelists noted that this particular usage might be acceptable if Susie had in fact moved to California in order to find a husband, in which case the story could be taken as exemplifying the folly of supposing that we can know what fate has in store for us. By contrast, 73 percent accepted the sentence Ironically, even as the government was fulminating against American policy, American jeans and videocassettes were the hottest items in the stalls of the market, where the incongruity can be seen as an example of human inconsistency."
This definition of irony seems to apply: 2a "Incongruity between what might be expected and what actually occurs: "Hyde noted the irony of Ireland's copying the nation she most hated" (Richard Kain)."
So I'm saying its ironic that although Slashdotters felt there was a 'coverup' as to why Slashdot had yet to cover the story -- it was in fact covered.
Their expectation of a coverup being 'incongruent' with the truth -- that the story wasn't covered up, and that it was posted.
By that 2a definition this seems to hold the characteristics required of 'irony' -- which should lend itself to the the word 'ironic'.
I'm not an English major, I'm only working with what I read in the dictionary. Please help me to understand it better if my logic isn't following correctly.
Perhaps what I thought in my head I didn't explain well in my post as to why I felt it was ironic.
not only that -- but upon thinking about it -- if my logic is correctly about how its listed there -- then why aren't ns1->ns4.google.com listed there also? why doesn't any domain have its dns servers listed when such a search is performed? (Does whois filter out dns servers listed within the domain itself?)
ala, google.com uses ns1->ns4.google.com, so it doesn't list them?
How very christian-like of you. I'm sure all of your customers applaud your methods; and will flock to your business upon hearing that you're harassing children.
If you're living this close to a month-by-month that you're personally hurting because of a sudden change in your business profits, perhaps your business was not quite as successful as you thought (for 12 years) and you should've been looking into other ways to make money.
If this is not a sudden change, then perhaps it would've been prudent to come up with another source of income, or way to make a direct change to YOUR store many years ago.
You're welcome to propose ideas such as this, but don't fool yourself into thinking you'll see a change tomorrow. You'll be on the street for many years before we start the sex offender equivilant of a Copyright Offenders List (Especially considering copyright law is CIVIL and not CRIMINAL)
Everyone keeps freaking out because when they run a whois query they get this:
GOOGLE.COM.SUCKS.FIND.CRACKZ.WITH.SEARCH.GULLI.C OM GOOGLE.COM.HAS.LESS.FREE.PORN.IN.ITS.SEARCH.ENGI NE.THAN.SECZY.COM GOOGLE.COM
This is NOT at ALL indicative of a hack.
All this means is that gulli.com chose to register a DNS server with their registrar called 'GOOGLE.COM.SUCKS.FIND.CRACKZ.WITH.SEARCH.GULLI.CO M' instead of ns1.gulli.com -- to do EXACTLY what they just did -- got your attention.
Simmer down everyone. If you whois ANY major site you'll see similar things. (Just try Microsoft.com)
There's no need to correct the words or pause after typing in and getting 'an' -- press whichever key is designated as the 'next' key -- and it will iterate through the next most popular word you may have wanted (which is am)
same goes for 'good' --
The pauses can be elimindated by pressing the designated key for terminating the pause (usually some sort of space or next key)
you don't even need to do that -- some (most?) cells there's a special key which performs the function of terminating the wait -- try space, or next buttons.
I don't see why people still cry about large indents -- If you're serious about your job, get a 21" monitor, and run 1600x1200 or higher; more on the screen, who cares about a now tiny indent.
How about Perl's POD Documentation?
I do a lot of hacking of Matt Simerson's Mail::Toaster and Nictool projects, and I find that the Perl POD Documentation system, combined with well-named variables is easy on the eyes, and leads to it being well interpreted by an outsider.
Although I was initially shocked by reading this, I'm not too concerned because I already use FlashBlock Firefox extension.
From the site: "Flashblock is an extension for the Mozilla and Firefox browsers that takes a pessimistic approach to dealing with Macromedia Flash content on a webpage and blocks ALL Flash content from loading. It then leaves a placeholder on the page that allows you to click to view the Flash content."
In most cases I've found this very handy, as ads on websites have recently been switching to a flash format (Yes, I could also be running the adblock extension).
For the few sites that I need it for (MBNA's Shop Safe Applet) I just click where the flash wanted to load, and it allows it.
I highly recommend this extension.
I now understand what those little flash icons trying to load in the corner of the browser were.
I can't believe they quoted Kevin Schmidt, campus network programmer for the Office of Information Technology as saying:
...although eGrades is accessible through the Internet, there are security precautions that protect it from unauthorized usage. "You have to use an encrypted web browser connection, so if you know that as the geeky https, you have to use an https connection, so that provides the real protection to it," Schmidt said.
I know I feel better now, knowing they protect people from accessing and altering their grading system WITH AN SSL CERT.
Surprisingly not. I don't even think they noticed me (though I was about 3 feet from them)
I've found quite the opposite - I go to Penn State University - main campus in State College, PA; and I ALWAYS see people taking photographs or video around campus, and no-one seems to care; they just go about their business. I've even just sat on a bench, and shot photos of people walking by for a long time, and not a single person noticed or cared.
I agree. My problem with most of these photo services is that they limit you to SMALL file sizes. Its understandable -- it takes a lot of space to host huge images. I just can't deal with looking at images that're pint-size.
I personally host all my 5MP images on my own gallery integrated with Mambo. I even did a little hack to enable Mambo-Gallery SEF URLs and a few other cool features. I'm not able to use my online gallery as my primary method of storing and organizing my photos.

I was very excited to try the ULE Scheduler for FreeBSD after having read the excellent article: ULE: A Modern Scheduler for FreeBSD.
