The ICANN started to allow non-latin alphabet to be used in the domain names to support half of the word which is actually using a non-latin alphabet (Russians, Chinese, Japanese, Hindi, etc.)

Google decided to celebrate with an anti-latin graphic to great their visitors.

With the repeated announcement of (minor) incidents with the security of the original PDF reader from Adobe, I wondered what could be a good replacement. Obviously, it seems important to stay around free or low prices (Adobe Acrobat: Windows/Mac/Linux, Basic: free, Pro: $299), but is it possible to beat the Adobe product to read PDF files?

• PDF-XChange (Windows, Basic: free, Pro: $34): loads real fast (much faster than the Adobe viewer), has all the basic options (annotations, graphic annotations, etc.) and the Pro version allows to reorganize the pages of a document or to extract text from it.
• Foxit (Windows/Linux, Basic: free, Pro Pack: $39.99): loads even faster, allows annotations (but only the Pro versio does it without watermark).
• Sumatra PDF (Windows, free): is even simple; everything is done for sheer speed.
• Apple PDF Preview (Mac, free): is very powerful (and it’s free, remember) and included in the MacOS offering; annotations, extraction, reorganization, all is available

Mac4Lin v1.0 is a free download for Linux systems which will allow your machine to appear very similar to a recent Mac.

If you want to grab the maximum CPU power for your PC video game (or any other PC application, by the way), there is a free utility that will ensure that the PC CPU does not spend to much time on anything else: Game Booster. It may be bad for a correctly balanced performance, but some games may appreciate the help.

Nota: This is similar to AMD Fusion Tool, but simpler.

It is not often easy to correctly evaluate the exact power needed for the Power Supply Unit (PSU) of your computer (if you buy primary parts and go the DIY way). Here is a calculator that will help you find the power output exactly needed for your PC configuration:

This factory exists in Dresden (Germany) and the visitors can see all the steps of the building of their own car. Right before your eyes.

However, my own experience with other car factories is that -even if they are not completely different- this is really slow manufacturing.

A good bookmark: Using OpenLDAP on Debian Woody to serve Linux and Samba Users is a user manual for OpenLDAP; But it does a lot more than merely explaining the installation of this directory on Debian Linux. It can be considered as a proper training to OpenLDAP in more ways than one.

But if you consider that this is not the right thing, you could thing a more organized (but less readable) description of LDAP: “Basics of LDAP” which is also very much Linux-oriented, of course.

I am not sure that this is exact all over the Internet, but I just noticed that this is true for YLovePhoto, one of my web sites: There are more visitors using Firefox than Internet Explorer.

YLovePhoto.com

Then, I checked for Roumazeilles.net itself, and I noticed the same situation:

Roumazeilles.net

It appears that Firefox is moving very fast. Who would have thought -a few years ago- that Microsoft’s world domination would be toppled like that?

Intel X25-M (SSD)

This is what is strongly suggested by an article published in The Register indicating that the Santa Clara giant would have suspended the shipments of its 2nd generation of X25-M SSD drives, because of a data corruption issue. We are waiting for a firmware update to correct this problem from what appears to be a tremendous product with low power, high performance and nice price.

Caution seems justified here.

Intel X25-M

SSD drives are those disk drives that are not using rotating platters with data stored magnetically, but that are based upon a set Flash memory components (so, without any mobile part, and with a performance that has nothing to do with even the fastest magnetic hard disk drives). SSD drives are expensive but, with costs are plummeting, the most expert and demanding users are starting to look at them dreamingly.

But everything shows that the SSD drives are not all equal (there is still an intense competition at this apex of performance). We see many a product recommended, often without all the technical arguments.

The “A look at SSD performance in Windows Vista – The more things change…” article from Geoff Gasior (The Tech Report) is definitely full of little gems because of that: It comes after a large number of tests (and many articles on the same subject) and compares finely the most representative products of the market.

Without telling it all (read the article. It’s worth it and you will learn many things), there are a few important conclusions drawn:

• Initial performance is usually much reduced after some time and some even light use,
• X25-M from Intel is probably the best drive around, the most well-balanced (recommended for a purchase in the short-term),
• The OCZ Summit is the faster in write operations (Intel is an ace of reading),
• the differences between suppliers come more from the controller used (Intel, Samsung Indilinx) than from the the brand.
• The arrival of Windows 7 (with its TRIM feature support) will probably change the situation (all the more because TRIM support is not yet certain from Intel) and, if you can wait, you will be better being patient and hope for Windows 7 and the new products and new firmwares made just for it.

Did you see the presentation of the next generation of TomTom navigation software? It will arrive on the iPhone 3G/3G-s.

For me, this was reason enough to get my own iPhone 3G-s last Saturday.

If you have Windows installed on your PC, you may have noticed one surprising thing: File copying is amazingly slower than what it was in previous editions of Windows or on other kinds of computers. The exact reason is a bit unclear (some say that it is linked to some Digital Rights Management features kicking in any time you copy a file, but this is still unproven to my knowledge) but this became a very annoying issue for people who have to copy either lots of files (backing up your daily work is a good example – by the way, did you make your daily backup yet?) or some very big files (moving video files around your computer is the archetypal example).

This situation led to the appearance of a few optimize file copy utilities (a software category that did not exist a few years ago, but a useful one). Let’s look at 4 of them which have the enormous advantage of being completely free:

• SuperCopier: Its strong advantage is that -after installation- it replaces completely the default Windows copy for drag-and-drop (it works nearly without thinking about it)
• FastCopy is fast but forgets mostly about being beautiful. However, it has a few interesting (and unique) options to configure the way the right-click menu appears.
• RichCopy is the internal Microsoft solution to their own bug/issue. Amazingly configurable, you can setup profiles for different uses (probably too much for most users, though) but I couldn’t find how to insert it in the right-click menu.
• CopyHandler: You can’t get more technical than this one! Options include things as obscure as buffer size depending on the type of file copy you do (disk-to-disk, directory-to-directory, disk-to-CD/DVD, etc.) The best little gems here include the possibility to pause/restart file copying, shutting down the computer at the end of a copy session, or scheduling a copy session for the next login.

All of them get rid of the usual flying folder kind of window and replace it with a more technical-looking window with progress bars and more optional lists of details.

Anyway, even if I can recommend all of them (a little preference for SuperCopier), remember that they are not even useful (in terms of copying speed) in Windows XP or Windows 2000. But, if you are using Windows Vista (mostly) or Windows 7, you should seriously consider them.

I consider that the most useful and often the most interesting wallpapers for your computer desktop are images that are relatively feature-less. A picture full of little details continuously grabbing your attention is a major nuisance. It’s much better to have either a very smooth image or a photo containing a lot of continuous tones.

Windows 7 official wallpapers

Look at the full set of the Windows 7 wallpapers. This is the upcoming version of Windows (after Windows Vista, it seems that Microsoft intends to switch back to a numbering scheme). Most of them may be colourful, but with very smooth surfaces where your icons will be appearing quite neatly and they offer a nice contrast.

So, I was quite interested when I stumbled upon the collection of pictures taken by the HiRise (High Resolution Imaging Science Experiment camera installed on board the Mars Reconnaissance Orbiter). Shooting photos of Mars surface, this photo camera brings extraordinary color images that provide nice patterns to be used as background for your Windows desktop (or even Linux or Mac desktop) and can be renewed quite regularly: Their catalog is available on the University of Arizona web site.

Furthermore, they provide an enormous resolution for their images which is a very good way to extract any size you may need for your extra-high-resolution background or to cover your 2- or 3-LCD display. Or even more. If you feel that there own selection of wallpapers is not enough:

• 800×600
• 1024×768
• 1152×864
• 1280×960
• 1440×1080
• 1600×1200
• 1920×1440
• 2048×1536
• 2560×1600

You can still stick to the original size (JPEG-2000 format images range between 0.5GB and 3GB).

And the good news is that there is no copyright restrictions, so you could do pretty much what you want with them: Really free desktop wallpapers.

We had forgotten that it existed, but this major pioneer of the modem age of computer communication, Compuserve, has now officially closed its doors. It had been trampled by AOL before loosing ground in front of the Internet explosion. But, now, there is nothing left of the communication service we (I) used to exchange information before SPAM could happen, when speeds were measured in bauds.

The Deutsches Technikmuseum Berlin is a museum presenting a large mount of technology history. Quite naturally, they are biased toward presenting a lot of German achievements and this country is known for hosting some of the very best optical engineers and being rightfully proud of brands like Carl Zeiss, Leitz/Leica.

Charlie Sorrel wrote a piece of article for Wired.com, titled “Gallery of Sawn-In-Half Cameras” that I intensely recommend reading.

Simply the best video player for Windows, VLC, just quit its long beta phase. This is official now, VLC v1.0.0 is available with a list of small improvements brought to an already impressive product that I can only recommend if you are using video (to read DVD, BluRay, HD-DVD discs; to stream videos from your computer; to convert your videos; and I sure forget some).

If you want to know more, you can even buy those horse legs.
