This morning I was sitting here watching the STS-127/ISS EVA #2 that's continuing work on building the ISS as well as listening to the Apollo 11 mission audio in real time (well, real time but 40 years after the fact).
Now, as has been widely publicised recently, NASA had overwritten the original Moon landing tapes during routine tape reuse due to limited funding. If only someone had thought to have a Historian employed at the time... Hindsight is normally 20/20! :) The footage that's currently being restored and enhanced was located, if I recall correctly, in Perth, Western Australia.
One sad note in the 40th Anniversary celebrations is that Walter Cronkite, the broadcast journalist that much of the 600 million people watching the Moon landing were listening to, unfortunately died on July 17, 2009 - just a few days before the 40th Anniversary of the first Moon landing. Walter Cronkite was also well known for his broadcasts of a number of other historic events.
So, as I sit here in Brisbane, Australia watching live, streamed vision from the STS-127/ISS and listening to the Apollo 11 audio, all I can think of is the words of the gorgeous and effervescent Patience Hodgson when she once said "Science is Golden". :)

112 = Cp
Finally, 13 years after it was first discovered, element 112 has a name. The team of scientists who discovered this element in fusion experiments in 1996 decided to name the element after the man "who changed our world view" and the IUPAC will endorse "copernicium" (Cp) in around 6 months, giving the scientific community time to discuss the name.
Nicolaus Copernicus was the man who proposed in his De revolutionibus orbium coelestium the heliocentric model whereby the planets actually orbit the sun, not the Earth - a fact that was pivotal in discovering and understanding gravity and in realising that the stars are a great distance away and that the Universe is, well, rather large. This publication was one of the major starting points for the scientific revolution of the 16th century.
De revolutionibus orbium coelestium was delayed for publication by Copernicus until just before his death, likely reason for this delay was that the religious narrowmindedness of the time would have resulted in religious persecution because of his findings.
We all need to have a beer/bourbon/scotch/coffee/water/whatever in honor of scientists like Copernicus who have enlightened us. The mind is a wonderful thing and scientific principle is a wonderful way to develop our minds.

Australian Internet Filtering
With total and utter cluelessness and wanton wasting of Australian taxpayers' money, Senator Steven Conroy continues to plough forward with his attempts to bring Chinese-style dictatorial censorship of the Internet to every Australian citizen whether they want it or not. Thankfully, 2 different childrens' advocacy groups - Save the Children and National Children’s & Youth Law Centre - have added their weight to the growing number of advocacy groups, freethinkers, IT industry groups, parents and other Australian citizens who don't believe that this filter is the right way to spend our money.
To have a read of the joint statement released recently, click here.
What this Internet filter definitely will do is cost millions of our dollars, fail to achieve any of the goals such a project should be aiming for, increase the cost of Internet access in Australia, slow down Internet access in Australia, increase the amount of equipment ISPs need to run to provide Internet access (therefore reducing the reliability of the already unreliable Internet access we have here in Australia, impose a closed list (as in closed to public scrutiny) of blocked sites, reduce the freedom of every Australian, prove that we were once the "lucky" country but are now the "unfairly censored" country and eventually fail and be removed. Unfortunately, as I mentioned above, this will all happen after wasting millions of dollars of taxpayer money that could be better spent providing functional protection for our children through better education as well as a great many other things.
I wonder when we, as a people, agreed to have the Government take control of our morals instead of us accepting responsibility for them ourselves? I certainly don't remember that being an election issue, however it seems to be something the Government just decided that they could do better than parents can. I certainly don't recall democratically electing a dictatorship.
I wonder what it is with Senators with "Steven" in their names, Communications in their portfolio and no practical knowledge of this subject at all. First came Senator Ted Stevens in the USA who thinks of the Internet as "...a series of tubes" and gave the world, aside from a good belly laugh, a good understanding of his total lack of understanding of how the Internet works. Now comes Senator Steven Conroy who wants to try and censor Australian citizens' Internet access as if he was running a dictatorship, believing that this is a good thing and won't be a total joke, waste of money (as in *our* money), failure and example of how little the Government understands not only what the Internet is, but what freedom of speech means. Not that we have a Constitutional right to free speech as the American people have.

Microsoft IT Environment Health Scanner
For those of you who don't regularly read the EBS Team Blog, they have announced the release of the Microsoft IT Environment Health Scanner - a diagnostic tool designed for administrators of small or medium-sized networks who want to assess the overall health of their network infrastructure.
This tool, whilst based on the scanner in the EBS Preparation Wizard, is now EBS agnostic - it doesn't ask you about your EBS installation type before running it, nor does it offer the Windows EBS Readiness report after the scan. Other than that, it *is* the EBS Preparation Wizard health scanner.
If you've never run the EBS Preparation Wizard over your network, I'd strongly recommend downloading and running this tool. It is a good tool to run on your client networks - and especially on the networks of prospective clients to see how much work you have to do to get them on the straight and narrow...
Now, a bit of information that's not given to you in the documentation for this tool...
First, even though this is a tool that *should* be "run as administrator" (when UAC is enabled) by default it won't ask for elevation and even though it asks for an administrator account user/pass just as the health scan starts, this is not enough as you will receive 2 errors because the tool was not run with elevation - in Data Collection, you'll receive an AdReplConvergence error and also a SysVolInfo error, both resulting in a lot of checks being skipped. Honestly, how did this get past the beta testers like this?
On an SBS 2008 primary server (the SBS 2008 Standard bit) when you run this tool you will most likely receive a warning indicating that the server is configured to use only the default time source time.windows.com and then refers you to a KB article on how to fix this on Windows Server 2003. Well, SBS 2008 is *not* based on Windows Server 2003, so a better KB would have been... well... there is no Microsoft KB on how to do this in Server 2008, however Richard N Williams (aka "the man who knows ntp") wrote an article on this which can be found here. However, despite the health scan warning, unless you have either a) a seriously unreliable Internet connection or b) a local hardware clock that's more accurate than your motherboard clock, such as the Star Card, then using time.windows.com will do fine. Personally, I prefer au.pool.ntp.org for our Linux and BSD servers as it is physically closer than time.windows.com, however on Windows systems, I usually stick with time.windows.com.
Additionally, this MS IT Environment Health Scanner fails to perform one check that the EBS Preparation Wizard performs that I consider quite useful - "Dynamic Updates are enabled on DNS root zones". It also fails to perform "Domain controllers that are running Windows Server 2000/2003 have the correct service pack installed" which could be a useful thing to know.
So, between this MS IT Environment Health Scanner and the EBS Preparation Wizard, which should you choose? Well, if you want to use the scanner that does the most thorough check of your network, use the EBS Preparation Wizard tool - but just remember to tell it that you'll be joining EBS computers to an existing AD domain.

McAfee McDestroys McComputers
According to The Register, McAfee has been at it again, releasing another DAT file (5664) that has decided the regular (and critical) core Windows system files are malicious and need to be removed, resulting in both a BSOD and an unusable machine in a number of cases.
I wonder when AV vendors (all of them, as pretty much all of them have done this from time to time) will realise that a proper test of their database updates before releasing them is an essential part of the customer service they need to provide to their own customers?
Sure, getting databases updated for new, active, infections malware is important, but so is leaving the machines that your customers run your software on in a usable state. The two are not (and should not) be mutually exclusive!

Getting started with Companyweb
Robert Crane has released his latest eBook - Getting started with Companyweb - which gives a good overview/introductory tutorial to using the Companyweb feature of SBS 2008. I've had a quick read through the eBook and it seems to cover the basics quite well, with his Windows SharePoint Operations Guide taking the reins from this point and dealing comprehensively with all aspects of SharePoint Services - the product on which Companyweb is based.
Regards,
The Outspoken Wookie
Companyweb is a very powerful component of Microsoft Small Business Server 2008. It is build using SharePoint technology that is also available on most other Windows Server editions. It is the starting point from which you can create a solution to solve your collaboration needs. Basically, all you need to know is that Companyweb is a standard tool, much like Word or Excel that you can easily customize to suit your business needs.
This document has provided a very basic overview of some of the most common features available with Companyweb as well as taking you through a basic tutorial of these features. This document should make a great starting point for anyone wanting to come to grips with the basics of Companyweb on Windows Small Business Server 2008.

VoIP and QoS
There was a question posted on the Brisneyland SMB IT Pro group list earlier which is an oft-heard question regarding VoIP, QoS and what can be done to get the best results. The following was my reply...
Stay tuned for more exciting episodes of VoIP and QoS when either a) I can be arsed writing some or b) you ask for more.
Regards,
The Outspoken Wookie
There’s actually *no* voice traffic going across port 5060 at all. Not a schmick. Nada. Port 5060 is the SIP port, correct, but SIP means Session Initiation Protocol, which is where one end says “Hey, good lookin’, whatchya got cookin’?” and the other replies with “Some goose here wants to call some idiot on your end. Are you up to it and can you be arsed taking the call?” to which the other end replies “Sure, why not – I’ve just had a relaxing weekend off. Tell ‘em to use g.711 alaw and send their voice data through port 13294 and I’ll see what they want.” Or words to that effect.
Basically, SIP traffic is a simple handshaking that goes on before and during an RTP session. That’s all, so it uses what’s technically referred to as “bugger all” bandwidth.
Now, the RTP traffic, which contains the meat part of this sandwich, uses other ports, generally between 10,000 and some higher number. These port numbers are defined by the VoIP system you’re using. It is these ports that need to have QoS applied to them as it is these ports that contain the critical data such as “Darl, when you come home tonight, you need to bring some milk.” And “OK, love, anything else you need, like a big manly hug?” “No. That’s not going to work tonight either.”
So, if your router and network can apply QoS, it needs to be applied to the right ports/traffic, however if they are sharing this Internet connection with their data, don’t expect miracles (unless they are next to the telephone exchange). Also you need to remember that 99% of the data that is QoSed inside your network loses that QoS when it hits the ISP’s network, so you can really only QoS a) outbound traffic until it gets past the gateway and b) inbound traffic *after* you’ve already received it.
Stay tuned for more exciting episodes of VoIP and QoS when either a) I can be arsed writing some or b) you ask for more.

Why We Don't Support Opera
With the recent stink that the Opera browser makers are causing in the European Commision with regard to Internet Explorer 8.0 being included in Windows 7, I thought it only fair to explain the reasons behind why we don't support Opera here at Quark IT.
1. There are no .adm templates available for it (that we've found), meaning that it cannot be controlled on a company-wide basis through Group Policy
Well, that's pretty much it. OK, so it is only one reason. Even Firefox has an .adm template file available which means that in business networks, defaults and preferences can be set to a company policy. Opera just doesn't seem to get this. Even Thunderbird has the ability to have *some* form of company-wide control, although it isn't as easily deployed as an .adm template.
Opera has been designed for the home user, not the business nor enterprise user. Or so it seems to me, since they have no way (that we've found) to effectively control the software on a company-wide basis.
Now, add to this that Windows "N" that was released to satisfy the European Commision masturbators has sold about, well, SFA copies - it is reported to be around 0.005% of all European sales of Windows XP in Europe by April 2006 (please note that these are rather old figures). So this should be AMPLE proof that the European Commision is not acting in the best interest of EU consumers.
As I've said before, were I involved in releasing Microsoft products in the EU, I'd mark all regular versions of Windows as "Not licensed for use in EU countries" and release appropriately crippled software to fully comply with the European Wanker Commision - no mail client (oh, there's none in Windows 7 any more anyway), no media player, no web browser, no video editor (and yes, that's gone from Windows 7 also), no nothing at all that the EU wanker commision can complain about. And then sell this at the same price that they sell the rest around the world. And then either make the individual components available for free download (just like Opera is) and/or via Optional Components in Windows Update.
I have never had an issue with calling a spade a spade - as Microsoft well knows by now - however when there's a witch hunt out against any company (and in this case it happens to be Microsoft) then something needs to be done about it. Apple can include Safari and iTunes in their OSX, so why can't Microsoft include IE8 and Media Player?
Fair's fair.

Core i7, Xeon 5500 and DDR3
I've seen and heard a number of fallacies surrounding the current hardware platform by Intel and in this blog post I want to set people straight.
Q1. Lets put it this way. HP themselves have bundles with 2 slots occupied as their "recommended" configurations.
A1. Yes, that's correct. However this doesn't fully utilize the RAM bandwidth available to a Xeon 5500 series processor as compared to Triple Channel DDR3. As with the move to Dual Channel RAM back in 2002, Triple Channel will result in a performance improvement over Dual Channel. Admittedly, it isn't as much of a performance improvement (due mainly to the newer cache architectures in modern CPUs), but it is still an improvement. So, if you want the fastest performance from a particular type of RAM, Triple Channel will be faster than Dual Channel will be faster than Single Channel.
Q2. I think the triple channel only works with twin CPU setups (ie. Not with one CPU) AFAIK
A2. No, that's not correct. In multiple-socket motherboards, half of the RAM slots (in a Triple Channel bank) are available with one CPU installed and the other half with the second CPU installed. Obviously for 4-way systems, 25% of the RAM slots will be available per CPU installed.
Q3. Won't DDR-1600 always be faster than DDR-1033?
A3. No. Not only does the memory speed matter, but the latency matters. The latency often matters more than the overall memory speed as it results in faster retrievals of small quantities of data, whereas a faster overall clockspeed will normally result in faster transfer of larger quantities of data. If you want to have a good look at the differences between RAM clock speeds and latencies, have a read of this Tom's Hardware article.
Q4. Aren't the Core i7 CPUs really just a Core 2 Quad that's been stuck into one package instead of a pair of Core 2 Duos glued together?
A4. No. The Core i7/Xeon 5500 series CPU core and cache architecture have been redesigned. There's significant differences between the way a Core 2 and a Core i7 CPU work, not just the doubling of the cores on the one die.
Q5. Is a Core i7 with DDR3 really faster than a Core 2 Quad with DDR2?
A5. Yes. A comparison of a Core i7 920 (the slowest one available - 2.66 GHz, 8 MB L2 Cache) with a Core 2 Quad Q9400 (2.66 GHz, 6 MB L2 Cache) or a Core 2 Quad Q9550 (2.83 GHz, 12 MB L2 Cache) will likely result in a 10% or more increase in speed. Of course that will depend on the applications you use, however if they are modern apps (multi-threaded) then you'll see around this or more. So, at the same clock speed, you'll see a performance improvement.
Q6. Is it true that Hyper-Threading makes a triumphant return in the Core i7/Xeon 5500?
A6. Yes and no. Xeon processors have always had Hyper-Threading (since it was introduced) however the Core i7 definitely heralds the Return of Hyper-Threading in the desktop processor space. :)
Q1. Lets put it this way. HP themselves have bundles with 2 slots occupied as their "recommended" configurations.

I'd heard about Google Wave before but hadn't had time to have a look at it. After being prompted to look into it by Ray Ozzie, I watched the developer preview at Google IO 2009 and must admit that even though there's not a lot of functionality right now aside from emailey, IMey, document collaboration style stuff, it looks like it has a lot of promise.
Unlike Ray Ozzie, I think that Google making this project available as Open Source is a great thing - not only for both Wave and for Open Source, but also (importantly) for the consumer. Now, we all know that Microsoft sees Open Source as the Great Evil, however those of us not tainted by the Microsoft rose-colored glasses that Microsoft staffers seem to have surgically implanted don't all agree with this view. I'd find it hard to find anyone outside Microsoft, actually, who believes that Open Source will bring the downfall of modern society, result in us all eating filth from open sewers and calling everyone who stands upright m'lord! :)
So, for those amongst us who are able to see the world out of both eyes, when Google Wave is available for public consumption, I'll more than likely blog about it. I'd encourage you to have a look at it and see if it can help some of your clients' and your own collaboration scenarios and help increase productivity.

Search Engine Updates
It seems that both Microsoft and Google have started to beta their new search engines. The new Microsoft Bing looks really pretty and somehow actually returns relevant results (unlike their current production-grade Live Search which has been replaced by Bing) whereas Google's new Google Squared isn't quite so functional/effective from what I've seen thus far. Maybe I need to use Bing a little more to test the relevance of its results and see if it *really* has improved or just looks prettier.
Google Squared seems to need to be massaged a lot to to get decent results, and that's not going to work for quick searches, but I (kinda) like what they are doing with the results.
