Research companies on the web

(Tuesday, July 3rd, 2007)

In France, we have public and private services to research information about existing and past companies. The best example is certainly and other services described in “Euridile et Cie - L’information financière à propos des entreprises françaises“.

But when you are speaking about American companies it seems that things are a bit more complicated. That’s not true. Thanks to Learn Web Skills, you can research companies online:

  • Locate High-Level Company Information (including ticker symbols, Hoover’s online, Business.com, Public Record databases at searchsystems.net
  • Identify Telephone Numbers and Addresses
  • Locate Company Home Pages
  • Research Company Financial Information
  • Monitor Company News and Periodicals
  • Review Public Opinion
  • Learn about an Industry
  • Use Business and Financial Meta-sites
  • Locate Professional Associations
  • Find Conferences and Seminars
  • Find Sales Prospects
  • Research Nonprofit Organizations
  • Identify International Business Resources

This is a very good compendium of information.

Crysis, the official web site is out

(Tuesday, July 3rd, 2007)

Crysis is expected to be one of the biggest hits for PC games in 2007. Today, Electronic Arts launches the official Crysis web site.

Velcro is a marvellous invention. And it is impressive when shot in micro-photography: A very unusual image.

Summer PC: Motherboard and memory

(Monday, July 2nd, 2007)

  • Gran Turismo: An enthusiast’s PC geared towards PC gaming
  • Easy Penny: A very reasonable PC able to sustain a few years without letting its owner down

Having previously chosen AMD processors for the two optimized PCs we are trying to build, things will be relatively easy. The integration of the memory controller in the CPU is a great advantage since it levels off the competition for performance. We only have to choose based upon options and features.

For Gran Turismo, the fastest PC, we decided to favor extensibility with many external peripherals. We opted for the ASUS M2N32-SLI Deluxe motherboard:

  • Passive cooling to limit noise
  • Two PCI Express 16x slots with SLI support to accept a future two-graphics boards configuration using nVidia SLI boards
  • Many interfaces (USB, FireWire, SATA II)
  • ATX format, for an easy choice of computer case

Barette mémoire DDR2-SDRAM-800-PC6400We will add 2GB of DDR2-SDRAM memory using two slots with PC6400 - 800MHz in CAS 5-5-5-12 configuration (two sticks will be better than one from the performance point of view). The extensive price drops of this year are very helpful leading to only 86€ for Corsair-branded memory sticks.

If you happen to be willing to play with games under Windows Vista (for example, in order to take advantage of DirectX 10 that is not yet available under Windows 2000 or XP), you should seriously think about going up to 4GB (more or less, 2GB used by Vista and the rest being eaten up by big games or memory hogs like graphics applications or PhotoShop CS2). For a mere 86€ more, of course.

Gigabyte GA-MA69G-S3HFor the cheapest PC, we needed to keep the ATX format advantage, but the integration of a graphics card woudl allow to lower down overall price significantly: We opted for the Gigabyte GA-MA69G-S3H motherboard that has an on-board Radeon X1250 graphics chip to avoid paying a separate board (it will be possible to buy one later when money is available to the owner).

Its memory will be limited to 1GB for now, but you can easily extend it now (for a limited cost) or later (when really needed).

We will add more to the configuration in future posts, but we currently have:

  • Gran Turismo: 113€ for an ASUS M2N32-SLI Deluxe motherboard and 86€ for 2GB of DDR2-SDRAM (current total: 367€)
  • Easy Penny: 91€ for a Gigabyte GA-MA69G-S3H motherboard and 43€ for 1GB of DDR2-SDRAM (current total: 232€)

All prices are the best we could find in France at writing time.

Massive collection of stunning photographs

(Monday, July 2nd, 2007)

The page has been digged so much that they had to move to a different server, but it’s still a very nice collection of impressive photographs (think “saturated colours”) from all origins.

I would even suggest that most of them would make great desktop backgrounds for your computer.

Summer PC: Processor (CPU)

(Sunday, July 1st, 2007)

Building the best possible PC for a set budget, taking into account the current market prices has always been a difficult task. We are starting today a series of posts to define the needed PC components to build an optimised PC (not only good components, but a solution as homogeneous as possible for a given application). We invite you to follow up while we build here two machines:

  • Gran Turismo: An enthusiast’s PC geared toward PC gaming
  • Easy Penny: A very reasonable PC able to sustain a few years without letting its owner down

In this beginning of Summer, it may seem like a preparation for Fall rush for computers (not only for students starting a new college or university year).

To start with, we will check how to choose the CPU (in a still very competitive commercial environment: AMD vs Intel, single or dual core, fast or cheap?) Those who dream about quad cores should wake up: To start with, prices are preoperly out of bounds for Core 2 Quad from Intel (not less than 500€ for a Core 2 Quad Q6600), leaving it out of our scope. Then, AMD is still pushing its quad-core solution for August and we don’t know what availability they will have then.

Nevertheless, it has become clear that dual-core solutions have entered the mainstream. The Core 2 Duo line from Intel is nicely spread all over the place but the diversity of models is making things a bit more complicated than necessary. AMD has less options and has left the field of higher-end performance. However, for normal applications like ours (let’s stay in the 150-200€ range for our best machine and less than 100€ for our penny-less student), the competition is quite hard. All the comparison articles I could find indicate that AMD and Intel align their offers on the same price for similar performance. Obviously, there are minor differences if you test one specific program, but don’t expect much: Two 150€ CPUs have the same performance (open markets are good for this).

AMD Athlon 64 X2 5600+For our enthusiast PC gamer, we decided to set our aim at the AMD Athlon 64 X2 5600+ (leaving aside the direct competitor of Core 2 Duo E6400). Accoridng to Tom’s Hardware, the difference is small, but I was attracted to AMD by the lower power consumption and the integration of the memory controller that levels the playground for motherboard leading to a competiton on features only (see next post).

For the cheapest PC, the recent arrival of double-core processors under the 100€ limit such as the AMD Athlon 64 X2 4200+ is a godsend (the single-core CPUs are now officially at the end of their life). Up to now, we only had the ageing Pentium D in this price range. Curiously, now, the Intel Core 2 Duo E4300 is still a little over that 100€ limit but this could change quickly. Our choice: AMD Athlon 64 X2 4200+ using the AM2 socket (let’s avoid the old 939 socket at the same price but with less of a future for upgrades in the AMD offer).

We will add more to the configuration in future posts, but we currently have:

  • Gran Turismo: 168€ for an AMD Athlon 64 X2 5600+
  • Easy Penny: 98€ for an AM2-socket AMD Athlon 64 X2 4200+

All prices are the best we could find in France at writing time.
