Bin Selection of Processors for low TDP

This all started when researching whether a 95W processor would be a problem on a motherboard that had a recommendation of 65W.

The jury seems to be out on that one - but it does highlight a number of points.
The TDP is a "nominal" or a maximum value for the specified processor (it is likely that your processor will consume less power and processors can be selected from production runs for units that exhibit low power consumption)

These processors can be sold at a premium or they can get re-branded as low TDP devices. Due to the nature of how Intel and AMD market their products it is not clear how this manifests itself. Those at review sites, such as Anandtech, can speculate on this - but it will probably remain unknown to the exact state of affairs.

In any case, it is probably true that processors that have a lower TDP are not necessarily better capable to be overclocked. This seems to be the #1 concern of the "fanboys" on review sites.

NemesisChild On an AMD forum says: "Do your research!"

On the Zotac website: "GF8200-C-E with Phenom X3 8750 (95w TDP) 65w motherboard with 95w CPU" - this is the board I want to use a 95W, a poster comments:
"on here one person responds with a list of approved processors that says you can't use anything higher than 65w, but then it looks like a Zotac moderator says you can:"

The "Moderator" says:
"Any processor compatible with any AM2+ board should run fine. A BIOS update may be needed to recognize the name of processors released after the most most recent BIOS."

I am not sure that it does - I don't know that Infested Nexus is a Zotac Moderator (Update: Looking deaper on the Zotac website - Infested Nexus seems to be the main contributor - However, his profile says nothing of him (or her) being the moderator - I recieved my Zotac GF8200-C-E Motherboard - a quick look at the documentation - Zotac are not Asus! There will be a review of the ITX project posted later (see link below).

The links to these quotes were on my website, they will be republished on this blog.

My intention is to use an AMD 550 (95W) on the Zotac itx board - I purchased the m/b with a 190W AMD Phenom II X4 965 (which is going to be used in my "7 Box") - this would be "pushing it"

Quad Core Faster than Dual

When it comes to media rendering.

I know that I may be "pissing into the wind" here but I am trying to find some evidential indication that a Quad Core computer is actually better than a Dual for watching media, bith from DVD, BD and downloaded torrents.

I am not looking for benchmark tests - of course they are going to say that the Quad is faster and have numbers to back it up. Especially if the figures come from the manufacturers, Intel and their shills in particular (tests that seem to be designed to make Intel devices perform better - AMD not even featuring on their charts - or if they do, it is arranged that the tests that might give them an advantage are down-played).

What I am looking for are comments from those that have upgraded from Dual Core systems to Quad Core and have noticed an improvement in performance. Although I am not into gaming, the fact that games such as Crysis and COD4 (Modern Warfare 2) can be played at higher frame rates (real figures needed here though)

Xandros Linux

Many reports have been made by users and purchasers of the EeePC installing Ubuntu and WindowsXP. Asus even advertise that the EeePC is WindowsXP capable and supply drivers forit when you purchase it.

Drivers for XP are also available on-line (and on a CD with the unit - along with a guide to installing XP), and details on how to do this are published on the eeeUser com website.

Why! - the Xandros Linux is fine! Especially when you invoke the "Full Advanced Desktop"

Web Design and content guidelines

Disseminated from the Google Guidelines - these are constantly being updated, best to make another search

These are the Design and content guidelines, the Technical ones will be discussed below

  1. Make a site with a clear hierarchy and text links. Every page should be reachable from at least one static text link.
  2. Offer a site map to your users with links that point to the important parts of your site. If the site map is larger than 100 or so links, you may want to break the site map into separate pages.
  3. Create a useful, information-rich site, and write pages that clearly and accurately describe your content.
  4. Think about the words users would type to find your pages, and make sure that your site actually includes those words within it.
  5. Try to use text instead of images to display important names, content, or links. The Google crawler doesn't recognize text contained in images.
  6. Make sure that your TITLE and ALT tags are descriptive and accurate. (Working on this!)
  7. Check for broken links and correct HTML. (Using Google webmaster tools for this)
  8. If you decide to use dynamic pages (i.e., the URL contains a "?" character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few.
  9. Keep the links on a given page to a reasonable number (fewer than 100).

  • Use a text browser such as Lynx to examine your site
  • Allow search bots to crawl your sites without session IDs ..............(TF doesn't use them)
  • Make sure your web server supports the If-Modified-Since HTTP header. (Not sure if I can do this)
  • Make use of the robots.txt file on your web server
  • .......make sure that your content management system exports content so that search engine spiders can crawl your site... (TF doesn't use CMS)
  • Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines. (Done)
  1. Make pages for users, not for search engines. - No "cloaking"
  2. Avoid tricks intended to improve search engine rankings. - "Does this help my users? Would I do this if search engines didn't exist?"
  3. Don't participate in link schemes
  4. Don't use unauthorized computer programs to submit pages
  5. Avoid hidden text or hidden links.
  6. Don't employ cloaking or sneaky redirects.
  7. Don't send automated queries to Google.
  8. Don't load pages with irrelevant words.
  9. Don't create multiple pages, subdomains, or domains with substantially duplicate content. (Blog has content removed so this doesn't happen intentionally)
  10. Don't create pages that install viruses, trojans, or other badware.
  11. Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content. (A "gateway" page was re-introduced April 2009 in a new approach)
  12. If your site participates in an affiliate program, make sure that your site adds value. Provide unique and relevant content that gives users a reason to visit your site first.
Duplicate Content

This page is probably seen as Duplicate Content by Google as per the Penguin update

The Wayback Machine

Alexa - ia_archiver and the Wayback Machine

The Wayback Machine is used to provide a historical record of how a website looked it the past.

The WayBack Machine from Alexa

ia_archiver is the search engine identifier for the WaybackMachine

What Alexa say:

The Internet Archive is a 501(c)(3) non-profit that was founded to build an Internet library. Its purposes include offering permanent access for researchers, historians, scholars, people with disabilities, and the general public to historical collections that exist in digital format.

 How to remove content from WaybackMachine's Archives

How the Wayback Machine tells you how to remove your content

If you place the User-agent: ia_archiver in your robots.txt when Alexa spider your website it will not only not index your pages it will remove your pages from its existing index.

In order for your information to be removed from the Wayback archives your website must be on-line and the norobots.txt file accessible. If you have taken your website off-line your content will remain in the archive for as long as the Wayback service is in existence. This could be problematic if the website in question no longer exists but continues to be found by those making searches.

Copyright Material and WaybackMachine

This is problematic as you may be being hassled to remove copyrighted images or content from pages that have been archived by the Alexa archiver. As this is an automatic process Alexa are probably not even aware that this is the case. As such, I think that you are well within your rights to say that it is a matter that the copyright holder needs to take up with Alexa themselves. At the same time check to see that the offending material is no longer hosted by your website.

You can always remove ALL of your pages from the Wayback Machine by making the entry in your robots.txt file, but you may want some of the pages to remain. I can see no way of doing this selectively.

Personally I don't care if all of my pages have been removed from their archive. I did this because I was being hassled by someone who had found an entry that was in the WaybackMachine and wrongly assumed my identity.

Hardware Virtualization - what it means

This is an attribute of a microprocessor. It is its ability to support Virtualization by the nature of the design on the chip.

Is SSHTunel.exe an Achilles' heel?

If I were an "Anti P2P Organization" (APO) I would try to inject data that would cause the SSH encryption algorithm to throw an exception.

Deep Packet Inspection

Irrespective of the measures you may take to obscure your identity your Internet Provider (ISP) will have a pretty good idea what you are up to on-line. Even if you connection is encrypted and being routed through a proxy or VPN the amount of traffic generated by downloading movies and music will be pretty obvious to your Service Providers DPI system.


More posts related to Interception of what you are doing on the Internet:

Rogers Cable Internet and JavaScript Injection

This post was formerly entitled: Rogers Cable Internet and DPI - the subject of the post is really JavaScript Injection so the title has been changed.

Below is the Injected JavaScript page that Rogers Cable generates to inform you that you have reached a certain level of Internet usage.

Along with monitoring your overall Internet usage Rogers use DPI to further determine the nature of your activity. They could, especially if mandated by the government, block ALL internet access unless you agree to some terms or refrain from certain activities.

These activities could include the downloading of files from a P2P (file sharing) service. It is likely that the demand is being made in response to a RIAA/MPAA email that they have received and have been requested that they take the following action:

Since you own this IP address (XXX.XXX.XXX.XXX), we request that you immediately do the following:

  1. Remove or disable access to the individual who has engaged in the conduct described above; and
  2. Take appropriate action against the account holder under your Abuse Policy/Terms of Service Agreement.

In the example shown here (the usage warning from Rogers) is a lesser version of what the ISPs are capable of. I have been informed of a Time Warner Cable subscriber having a similar message displayed that would not go away (and any other Internet access was blocked) unless they agreed to cease the activity of downloading a copyright protected movie.

While the Muse recognizes that the copyright holders are within their rights to protect their interests - using methods such as this are a "Thin end of a wedge" that threatens the whole concept of Network Neutrality.

Parting notes:
The message can be suppressed by turning off JavaScript in your browser (it is not known if this would restore your Internet access)
And, the Rogers message shown above does NOT mean that your Internet access will be, or is about to be, restricted. In my case the maximum that they charge me for usage over the 100% of my monthly allotment is only up to $25. This means I can happly go to 200 or 300% of my allowance!

Definition - Noun
: tending to cause anger, animosity, or indignation 

Evidence, and esp. photographic evidence, may be deemed inadmissible if its inflammatory nature seriously outweighs its probative value or relevance. The mere fact that evidence is graphic or gruesome, however, is not enough to render it inadmissible.


Anger, Animosity and Indignation was exactly what I was going for! as far as this is concerned I don't think any for those aims are illegal.
