overclocked a P4
from 2.2Ghz to an incredible 3.5ghz. There's plenty of stuff

i would have to loved to have been a fly on the wall in the oracle engineering department the day ellison announced that their software was unbreakable. i guarantee you the engineers at oracle wouldn't have supported that campaign, if they even knew about it before ellison announced it at comdex. it's tough enough to keep your software secure when your ceo isn't directly taunting every hacker in the world.
Well, because Forth to understand, like Yoda you must speak, that is.

That leaves me feeling warm and fuzzy inside.
In the other news, the largest ship in the world Titanic that was named unsinkable, has sunk.
Comments by the CEO: -Well, you can take it both ways, really, we are defining what Unsinkable really means! The other ship building companies in our field are looking up to us to be half as unsinkable as we are. It's great, really, how our compain brings the best out of this situation.
"We believe the market effect of the 'Unsinkable' campaign raises the unsinkability bar and therefore improves unsinkability overall, both in forcing us to live up to the statement, and forcing others in the industry to begin to do the same," wrote Bruce Ismay. "If our unsinkability today is imperfect but better than the competition, and if customers make a buying decision based on that criteria, than in the long term you will see all products in the market improve."
You can't handle the truth.
The fact that defense in depth is a good idea does not justify allowing one of the layers to be weak. The defenses at every level should be as strong as possible, and that ideally means a bug-free app server and a bug-free database.
The only thing that this researcher proved is that in certain environments you can break in the system, which basicly holds true for every system.
No matter what, you can be sure that contrary to M$, these holes will be worked on 24/7 and fixed like yesterday. :)
Anyway, enjoy you uninformed, senseless bashing and flaming... trolls.
If programs would be read like poetry, most programmers would be Vogons.
Come on people. Oracle explained that they used the term "unbreakable" because it passed 14 security audits. Some people say you can't crash linux because it typically doesn't - but it can.
:-)
By and large the Oracle products are very good... We use them in some extremely large and significant datawarehousing situations and have probably managed to kill the server once in three years. Many times we've been amazed at what developers have thrown at the server without killing it - Oracle is very good at recovering from users mistakes.
Anyway, I look forward to hearing what the obvious vulnerabilities are - I dread the number of server upgrades to be tested though. The client I'm working for now has about 250 instances registered with their 24*7 DBA team already... You have no idea how hard it can be to choose a unique 4 character SID sometimes.
Long live Oracle... I'm sure Larry won't lose any sleep (or money) over this since it is still clearly the best product out there.
I hate that quote.
When we have been programming for as long as we have been building things, then that quaote will be valid.
I am willing to bet that the buildings that where built during the first 50 years the human race had been building building wheren't all that good.
Yikes, what a sentence.

Dear Mr. Architect:
Please design and build me a house. I am not quite sure of what I need, so you should use your discretion.
My house should have between two and forty-five bedrooms. Just make sure the plans are such that the bedrooms can be easily added or deleted. When you bring the blueprints to me, I will make the final decision of what I want. Also, bring me the cost breakdown for each configuration so that I can arbitrarily pick one.
Keep in mind that the house I ultimately choose must cost less than the one I am currently living in. Make sure, however, that you correct all the deficiencies that exist in my current house (the floor of my kitchen vibrates when I walk across it, and the walls don't have nearly enough insulation in them).
As you design, also keep in mind that I want to keep yearly maintenance costs as low as possible. This should mean the incorporation of extra-cost features like aluminum, vinyl, or composite siding. (If you choose not to specify aluminum, be prepared to explain your decision in detail.)
Please take care that modern design practices and the latest materials are used in construction of the house, as I want it to be a showplace for the most up-to-date ideas and methods. Be alerted, however, that kitchen should be designed to accommodate, among other things, my 1952 Gibson refrigerator.
To insure that you are building the correct house for our entire family, make certain that you contact each of our children, and also our in-laws. My mother-in-law will have very strong feelings about how the house should be designed, since she visits us at least once a year. Make sure that you weigh all of thses options carefully and come to the right decision. I, however, retain the right to overrule any choices that you make.
Please don't bother me with small details right now. Your job is to develop the overall plans for the house: get the big picture. At this time, for example, it is not appropriate to be choosing the color of the carpet. However, keep in mind that my wife likes blue.
Also, do not worry at this time about acquiring the resources to build the house itself. Your first priority is to develop detailed plans and specifications. Once I approve these plans, however, I would expect the house to be under roof within 48 hours.
While you are designing this house specifically for me, keep in mind that sooner or later I will have to sell it to someone else. It therefore should have appeal to a wide variety of potential buyers. Please make sure before you finalize the plans that there is a consensus of the population in my area that they like the features this house has.
I advise you to run up and look at my neighbor's house he constructed last year. We like it a great deal. It has many features that we would also like in our new home, particularily the 75-foot swimming pool. With careful engineering, I believe that you can design this into our new house without impacting the final cost.
Please prepare a complete set of blueprints. It is not necessary at this time to do the real design, since they will be used only for construction bids. Be advised, however, that you will be held accountable for any increase of construction costs as a result of later design changes.
You must be thrilled to be working on as an interesting project as this! To be able to use the latest techniques and materials and to be given such freedom in your designs is something that can't happen very often. Contact me as soon as possible with your complete ideas and plans.
PS: My wife has just told me that she disagrees with many of the instructions I've given you in this letter. As architect, it is your responsibility to resolve these differences. I have tried in the past and have been unable to accomplish this. If you can't handle this responsibility, I will have to find another architect.
PPS: Perhaps what I need is not a house at all, but a travel trailer. Please advise me as soon as possible if this is the case.
A software company said to the public, "Our product is unbreakable." The public replied, "No, you are not unbreakable."
Another software company said to the public, "Our product is not unbreakable." And the public replied, "You're right, you are not unbreakable."
"Hello, helpdesk? I need to edit the Oracle config files, and I forgot the Oracle user's unix password."
"Hello, helpdesk? Brad Pitt's a friend of mine and will go out with you if you give me the root password for the Oracle box."
The more I've thought about this, the more likely it seems. And a key aspect to this is that my OS vendor, SuSE, and ilk (Red Hat, Mandrake, etc) would be nailed just as much as MS, except with less money in the bank, they would be killed much more swiftly. Now, two of those are outside of the USA, so it's not a direct correlation, but there are some serious ramifications to software liability that occur in as reactive a society as we have today.
Certainly this announcement would instantly have a dozen law firms seeking people running Oracle to launch a multi-billion dollar suit of some flavor. And while certainly not "unbreakable", and (IMO) a bit overpriced, Oracle being available is a Good Thing. Of course they have holes. I'm equally sure that they will likely address them quickly (Quickly being relative to the company involved). Introducing *sane* liability (at least in America) is going to be very difficult in a society that is making it neigh impossible to be a medical doctor, and is driving up medical costs due to the extensive CYA documentation (videotapes, extensive reports, etc) now required by industry insurance.

..."unbreakable" doesn't really mean unbreakable, or something...
Oracle said that 9i "is unbreakable". As President Clinton could easily tell you, the key word here is 'is'.

This is pure bullshit. Are the programmers of
Apache, IIS, Half-Life, Quake 3 Arena, Perl, SSHD, glibc, wu_ftpd, or BIND at the middle school level? Windows NT? How about the linux kernel? All have had buffer overflows, and I'll bet that many of them still do.
Unfortunately it is not always as simple as "putting limits on characters". The simple fact is that the C language is practically designed to make buffer overflow bugs easy to write and easy to exploit.
I agree with you that buffer overflows are serious, though. That's why I think it is ridiculous that we still write security-critical network software in C. Sometimes it is hard to get around, like in the linux kernel when you need to do hardware access (a microkernel architecture might make it easier to write certain parts in higher-level languages). You might argue that performance would be impacted (I don't think this is true, especially with network software where the network is the real bottleneck), but even this argument falls through for 99% of users, since most users are far from full utilization of their processor. However, almost all users *are* affected by security holes.
When I used to use Oracle it was unbreakable. The only people who had complete access was the DBA and some guy named Scott Tiger....
Other are just ports.
Well, yes and no. Oracle is developed in two layers, VOS or "Virtual Operating System" abstracts all the primitives like threads, pipes, file handling etc from the underlying OS, and Oracle itself, which is written to VOS APIs. So the core Oracle engineering team code for pure functionality, and the VOS teams keep their APIs in sync with each other on different platforms. If Oracle want to target a new OS or platform, they simply develop a VOS for it.
I believe the Oracle engineers work on Suns, but they are targetting VOS, not Solaris directly.
That's why you have to start the service before you can start the instance on NT. Win32 is sufficiently different from Unix-like systems to need an environment in place before starting Oracle, whereas Unix-like systems can just link the VOS into the main binary. It needs to work like this because Oracle is Oracle, on any platform, once you log into SQL*Plus, it's exactly the same. Oracle is more complex than many operating systems, it provides its own scheduling, resource quotas (storage and CPU), IPC mechanisms (AQ, DBMS_PIPE, DBMS_ALERT, etc), programming languages (PL/SQL and Java) and a whole lot more. It is a platform in its own right.
Dude. Overclocking with a super-cooling system is sooo 1999!
Good quote, too many chars. Seriously, the slashdot 120 char limit sucks!
...it just might be able to take the Slashdotting!
Are at it too.
Here you can see they've got it to boot at 3.674GHz. The page is in Finnish (I assume), but there's some English text at the bottom too.
Amigans have been overclocking their 68k series processors for years. Witness the 28MHz 68000 for the A500, or the 75MHz 68060s (instead of 50MHz), a 50% overclock easy when decent coolers are added to the equation.
It is harder to overclock the 8-bits, as the rest of the system messes up in many cases, and the video output and audio go haywire. But it has been done (Enterprise 64 in one example, upping the 5MHz Z80 by a MHz or two, or replacing it with ones that do 10's of MHz I believe. Dunno about the C64 or Atari 8-bits though.
I've got a plot showing SPECint2000 vs SPECfp2000 for eight different chips, including the Pentium 4 2.0 GHz.
From the looks of it, overclocking to 3.5 GHz might make the Pentium 4 almost equal in performance to the IBM Power4 running at 1.3 GHz.

If I put my Athlon in the microwave, I can get numbers out of it that don't exist in nature.

That the thing still functions at 77 Kelvin.
Incredible that the motherboard doesn't break, at that low
temperature, the resin should undergo a phase transition and become very, very brittle.
(Some notes for all those D.I.Y.ers out there:
Liquid nitrogen is cheaper than milk.
Short-circuits can't occur, N2 doesn't conduct.)
Although why he used nitrogen and not dry ice, which is cheaper, easier to handle, and probably
better for these purposes, beats me.
homemade nitrogen cooling system overclocked a P4 from 2.2Ghz to an incredible 3.5ghz.
Quick tip on "overclocking" from Ghz (Gigahertz) to ghz (gravity hertz): Throw your machine out the window. To get to decent speeds, you'll want to be at least on the 4th floor or above.
(Alternate tip: to perceptively increase GHz, throw the Windows out of your machine)
Can you really say that its the consumer who will win when no consumer programs require much processing power over a P2 400 or so?
I mean, it's nice that intel and AMD can make such fast processors, but where's the bottleneck on overall performance nowadays? I'm willing to bet it's not in the chip.
I think we've reached a point in personal computing where the software is years behind the hardware. Only in the fields of gaming or professional rendering do we need such high performance machines.
My friend's parents recently purchased a 1.5 Ghz Pentium 4 for day to day bookkeeping!
Son, do we need to remind you exactly how little power one needs to factor primes?
I Can't Believe It's A Law Firm, LLP does not necessarily endorse the contents of this message.
As an aside, I bought a game ages ago that must have been written for a 386/486 and ran it on my P233 (as it was at the time). The game was unplayable because of the speed. I dread to think how it would run on my Athlon 1800+XP... *shudder*
I think these guys are getting dangerously close to cause irreparable harm to the universe as discussed here.
I only post comments when someone on the internet is wrong.
Pretty much all you have to do to set overclocking records in Finland is put a jacket on and open a window.
That's what the "Turbo" button on the front of your case is for.
You do have a Turbo button, right...

Why don't you guys ever have any articles on underclocking? Are underclockers really that bad? What are some of the advantages of underclocking?
- Underclock a 2.0GHz to 1.0Ghz, and you can throw away your CPU fan.
- Underclock to 500MHz and you can get rid of your case fan.
- Underclock to 4.77Mhz and you can run older versions of Fligh Simulator.
- Underclock to 4.0 MHz and you can pretend you are running a Z80.
- Underclock too 100KHz and you can actually watch your instructions exeecute.
