Graphs, charts for a web site

(Wednesday, March 10th, 2010)

Sample chart

Sample chart

When you design a web site, it happens that you need to create graphs or technical charts. But this is quite difficult if you don’t spend a life drawing little charts or if you are not satisfied with the charts out of Excel (or OpenOffice Draw). For this, you need to have a good chart/graph package.

I found two of them that I want to share with you:

  • amCharts is a set of Flash charts for your websites and Web-based products. AmCharts can extract data from simple CSV or XML files, or they can read dynamic data generated with PHP, .NET, Java, Ruby on Rails, Perl, ColdFusion, and many other programming languages. I like the final appearance even if they could have more of a designer touch.
  • Chartle provides simple and interactive charts, maps, plots and diagrams. It’s still in beta right now (beg of 2010) but the results are quite good.

Fake Intels on sale

(Sunday, March 7th, 2010)

I already knew that there were fake electronic components of all kinds (don’t ask, but I work in the electronics industry and my own employer has sad stories to tell – but wouldn’t :-) ), but I believed that this was limited to small cheap components. I was wrong.

The US retailer NewEgg indicated this week that they found in their stock what appears to be fake Intel Core i7 920 CPUs. Actually, they would have sold a small number of them before becoming aware of the issue.

What a world!

Opera v10.50: New and fast

(Friday, March 5th, 2010)

opera_10.50

My preferred Internet browser, Opera, has now reached a new version v10.50. Not only is it still the same nice, friendly and powerful browser, but it packs interesting new features:

javascript_test

  • Faster: I did not try the beta versions so I was surprised: It’s fast, very fast. I am not sure if it warrants the “fastest browser on Earth” title that their promoter want to give it, but it is not often that you feel such acceleration from a mere version upgrade.
  • Win7-ready, perfectly integrated in Windows 7: Special menus for the integration into the icon bar, a specialized animated icon, optimized window, etc.
  • Private, secured navigation windows upon request.
  • The widgets can now be dropped onto the desktop.

Since Opera is compatible not only with Windows, but with Apple, Linux and most mobile phones, this is very good news about to spread around.

The Solid State Disk (SSD) is the new tool for computer performance. You no longer can consider yourself a geek if you did not try these Hard Disk Drives without any moving part because they are made of Flash memory. You will earn the semi-god geek achievement only if you trimmed, optimized, finely tuned, measured your SSD.

But, you can trick your way to the near-heavenly award if you go and check the Bit-Tech guide to trimming: “Why You Need TRIM For Your SSD“. This guide will tell you all that is to know about your SSD and Windows 7.

Model train lovers, get your magnifying glass!

(Friday, February 26th, 2010)

Really! It will be in strong need to admire this Z-scale model of an N-gauge train. It’s real small (it was used to recreate a small model train going in a shop window inside a Z-scale model train).

Admire the wonderful work of art!

SixthSense

(Saturday, February 13th, 2010)

The TED Talk conferences are often a great moment of technologie accessible to the largest numbers and an opportunity for the démonstration of what could be our future if the great thinkers of our time work on it.

The following conference (from Pranav Mistry) wants to give us a rought idea of perspectives opened by a rather recent technologie named SixthSense willing to put computers in our world rather than forcing us to flow in the computers mould.

It gets real speed and starts getting exhilarating after 6 or 7 minutes. Be patient, it’s worth it.

Thanks Xtian.

Even more pixels: Dresden

(Saturday, February 6th, 2010)

We have seen many, but today’s world record is a 26-gigapixel panoramic image of Dresden, Germany. I did not write 26-megapixel. It’s 1000 times what you’d expect from a better-than-high-end digital SLR photo camera.

This impressive photo is made of 1,665 individual shots captured with a Canon EOS 5D Mark II photo camera armed with a 400mm tele-lens, and combined together on a powerful computer.

IE6 is dead, says Google

(Friday, February 5th, 2010 by Yves)

Following our previous post about the evolutions of web browsers, it is interesting to notice that Google just announced that their on-line applications (GMail, Calendar, GDoc, etc.) will no longer support Internet Explorer 6 starting next month. It is time to go to a more recent (and more secure) technology, as mentioned before.

Update: I just learned that Internet Explorer 8 is now becoming the web browser most used in the world. Even if there is a lot of other good competition, Microsoft is still holding its position (from DownloadSquad).

Naked body scanners in airports: They don’t work

(Sunday, January 31st, 2010)

The debate rages, for a few weeks now, after the attempted bombing of the Amsterdam-Detroit flight in which a terrorist tried to ignite an explosive device hidden in his underpants. Shouldn’t we install this wonder technology that allows to strip naked search the passengers and to see anything they transport under their clothes? “Long live the body scanners!” shoot the industry, “This is the end of privacy in transports” reply the freedom rights partisans (and I will not even quote those worried about bringing up uniformed voyeurism).

But shouldn’t the first question be: “Does it work?”

A German TV channel decided to ask the question and invited a leading company in this field for a demonstration of such a machine in a TV studio under the surveillance of their best expert while submitting a “would-be terrorist” to a body scan.

You don’t need to speak German to understand what happened: All goes down the drain when the machine sees the wireless microphone box at the belt of the “guinea pig”, but -most important- does not detect the presence of several components of chemical products that will be used to manufacture a powerful explosive (very similar to what happened on last Christmas, wouldn’t you say?)

Technology failed here.

You really want to install those expensive gizmos in airports for the sake of theatrical security?


YouTube link

And don’t make me believe that this was unfair: No airport can hope to keep the manufacturer expert in front of the machine to analyze the images… The reality would be much worse. The fact that the “victim” did his best to hide the chemical products was just representative of what a determined terrorist would be trying with a real bomb.

Scan a book like a pro

(Tuesday, January 26th, 2010 by Yves)

The document scanner has long been a tool of the most usual appearance and scanning a digital copy of a document is now of such ease that anybody can do it. Nevertheless, there is a large gap between a pro scan of a full book and the slightly better than average Xerox-like copy that we all do.

Most of it comes from the use of masterful algorithms of cleaning, cropping, re-cropping, aligniment, correction, optimisation that are usually included in some very complex and very expensive pro software scanning tools. Thanks to Scan Tailor, this is no longer the cas. It is open source and it does it all like the pros.

IE6 becomes Firefox 3.6 with the help of China

(Sunday, January 24th, 2010)

This week has seen a pretty exhilarating story develop in front of our Internet eyes. Started as a muddy conflict between Google and the People’s Republic of China, it turned into a Firefox marketing victory. Let me summarize it a bit.

google chrome browser logo

In the beginning was Google which installed its servers in China in 2006. The “do no evil” company accepted the conditions of the government of the PRC and included heavy filtering and censoring of its search results (looking for Tienanmen will produce wildly different results in and out of China). But in January 2009, Google discovered that some hackers obtained some detailed information out of its own servers at this was targeting both American companies and Chinese political opponents or partisans of free speech in China. Subsequently, Google announced its intention of both lifting the censorship and leaving China.

What is still very unclear:

  • Is Google really serious about these two options?
  • Is the main reason for its ire, the political chase or the technological spying? (the US government including Hilary Clinton pushed hard with Google)

What is clear:

  • The breach of information seems limited (only email subject lines have been breached, not contents).
  • The hackers were affiliated to Chinese official bodies and did not only target Google.
  • The hackers used some social engineering and security issues present in Internet Explorer and Adobe PDF, which were probably known but not closed by Microsoft and Adobe.

So, when such information appears in wide open channels of the world press, what happens? Most experts started commenting on the security loopholes in Internet Explorer 6 (and about Adobe PDF reader, too). Many people observed that Internet Explorer 6 is rather old and it is unfortunate that so many people still use it despite the known fact that it is a security liability when browsing the Internet. With such a rush, some very official people also asked for replacement of Internet Explorer (mainly v6) to be replaced with more modern browsers. Even representatives of the German, French and Australian governments asked their countries to replace Internet Explorer with something else.

3x Firefox

3x Firefox

The competition has seen this as a godsend since it created a rush for the other available browsers. For example (see the graph on the side), Firefox saw a brutal explosion of its downloads in Germany (nearly 300,000 Germans have downloaded Firefox in four days): about three times more than usual. It has been true in other countries even if it was not measured as precisely, and it has been observed by the other browsers Opera, Safari, Chrome (currently profiting from heavy advertising in some European countries like France).

This was definitely a good thing since it was bringing better browsers to many computers. It could have stayed there but there were several reaction and parallel events happening at the same time. The first one was that Firefox was preparing a major upgrade to the successful browser (in many parts of the world Firefox is now used by more Internet users than Internet Explorer). Named v3.6, this new version is bigger than what could have been expected from its small number increase (from 3.5 to 3.6 should have been a minor upgrade). This major event accelerated the rush, with people looking for features like:

  • Built-in skins, to make it more personalized
  • Faster, more stable
  • More security conscious with the addition of user-level messages about risks, including reminders about what plug-ins are outdated and must be upgraded.
  • Visual tab previews, which show you the tabs when you press Ctrl-Tab
  • Aptitude to browse without leaving too many footsteps and traces in your PC (good for clean browsing like when you visit Adult sites)

This version is also appreciated by developers who will find a bunch of little improvements (like CSS gradients).

This is not only a great story to read. This is a great browser and you should consider downloading Firefox 3.6 now!

If you are not completely convinced, you should also consider downloading the newest Opera browser. Opera v10.10 has been available for a few months now and it also offering these advantages, plus some neat features like:

  • Opera Unite: to easily share information between Opera users and browsers, without using a web site or a share folder on some social network.
  • Opera Turbo: to adapt Opera to very slow Internet connections.
  • Speed dial: to get a faster access to some web sites you choose (bookmarks on steroids).
  • Mouse moves for faster commands.
  • Opera link: to share bookmarks, speed dial configurations between several machines where you use Opera.

Opera is clearly my preferred browsing solution (even if I need to test my web sites on everything I can find, Opera is the central hub of my Internet browsing). Go and download Opera v10.10 now.

And, if you are not sure yet, I can also offer the small and fast browser from Google: Chrome. Since it all started around Google and China, it was worth mentioning, of course.

All this has been going so fast that Microsoft needed to do something. Of course, they have a newer version of Internet Explorer (IE8 is included in Windows 7 and can be downloaded freely. But this was not enough, too many people were starting to complain that Microsoft may wait about a month before updating IE6 in the normal update cycle. Even worse, some experts started telling the world that Microsoft actually was aware of this flaw in IE6 for many months. In such conditions, not doing anything usually turns out to produce a public relations nightmare and prepares for bad wind.

So, Microsoft rushed an out-of-band update to IE6 and Windows Update is now offering the correction to all Windows users still using IE6 (of course, you still have to use Windows Update and it is well known that too many people do not have this configured or do not accept the proposed updates – this is wrong and one the reasons so many PCs are infected with Trojan horses, virus and adwares). Now, if you did not move to a later Windows version and if you did not take advantage of the much better IE7 or IE8, it’s time to upgrade your old hag.

We can expect to see a few more updates to this story in the future, but there is a lesson to be learned (by Google, and most Internet users):

Always keep your browser up-to-date and refrain from clicking on any link in a mail message you did not expect.

Additionally, there is a lesson for Microsoft:

Sorry! but even the older software has to be kept alive when you are or have been the near-monopoly on this technology. This comes with responsibilities.

The best mobile phone display

(Wednesday, January 13th, 2010)

All phones are not born equal. Some people seem to believe that the iPhone has a marvelous touch panel. But is this pure marketing BS? Is it Apple fans going overboard? MOTO, a small company supporting the development of high-tech gadgets and products, has created a (rather simple) test to check the precision and comfort of touch panels. It’s very easy: The tester will just draw simple lines on the screen and the software will display what the phone has recognized. Long lines drawn at an angle on the screen should display as such: Long lines.

Then, you apply that to a set of high-end phones: iPhone, HTC Droid Eris, Motorola Droid, Google Nexus One (the most prominent product on this mobile market). Of course, there is a difference if you press very lightly or if you push significantly on the screen with your finger.

All in all, it seems quite obvious that the iPhone has a strong advance in terms of sensitivity (light touch) while the HTC and Nexus One (HTC apparently designed this phone for Google) are quite good if you accept to press a little more.

So, Apple is not only marketing the iPhone through the roof; They also have a very good product and this explains (in part, at least) that the customers are so happy with the man-machine interface.

Find your free wallpapers with Google

(Thursday, January 7th, 2010)

If you’re like most people, you’d like to have pretty wallpaper on your desktop background. You can always go to wallpaper web sites but most of them are choke-full of ads and they always provide the same usual set. How about getting new ones?

Use Google.

Now, Google is able to search images by size. Just enter your screen size and you will be treated to a galore of images. If you also search for the word “wallpaper”, you are sure to find exactly what you need.

For my own 24″ screen, I could find brightly colored pictures or elegant designs. All designed to be wallpapers, even when no wide-audience web site had found it yet.

did I mention that it also works for dual-screen wallpapers? And did I mention that it’s free? (for a commercial use, this would not be an acceptable practice)
