à Mon PC de 1999

En février 99, après avoir lu un article sur www.kikumaru.jp qui relatait la possibilité de transformer n'importe quel Celeron Slot1 en Bi-proc en réactivant l'APIC responsable du SMP. Je décidais d'acheter deux Celeron slot 1 300A et de les modifier. Mauvaise idée, car j'ai surestimé mes capacités de soudure en ultra-cms. www.msi.comà eut la bonne Idée de fabriquer des adaptateurs MSI MS-6905 compatible Bi-proc mais non disponible en France à l'époque.à Unà mois et 330 francs plus tard, je reçois d'Allemagne les deux précieuses pièces (merci www.citosoft.com et MSI Allemagne (quel idiot ces Français, ZUT à MSI France et MSI Angleterre !), le temps de vendre mes 300A slot 1 et de racheter des PPGA 370 et NT4 en multi-processing me voila. Tout ça pour vous dire que il est vrai que selon les applications, le gain de performances n'est pas stupéfiant (des fois 90% ;-)) mais que le sentiment de puissance est bien la, NT ne semble plus d'essoufler quel que soit le nombre d'applications ouvertes, seul le disque dur reste la ressource critique qui freine les performances de l'ensemble (IBM UDMA 7200 tr/min). Toute les applications semblent bénéficier dans une certaine mesure de ce deuxième coeur d'après mes observations.

La facture s'élève à (Février 99)

Aujourd'hui, une Abit BP6 et le tour est joué (1140 FRF +2 cpu).

Tenter donc l'aventure si vos besoins en calculs pure sont important, c'est la meilleur affaire de la décennie et Intel ne referra pas deux fois la même erreur.

Nice case especially since I got it for 1/3 of its price (40€ at the flea market: a bargain)

The Antec Skeleton is a truly revolutionary enclosure. With a unique design that allows for unprecedented airflow, a front 92mm fan, and a top three speed 250mm fan with multicolor LED customization, the Skeleton goes utterly unmatched in stylish cooling. Factor in the layered component trays for top-notch convenience, as well as the rack mount quality side rails, and you have a case truly without equal.

The old case and the new Antec Skeleton case ready to be use. A smaller Antec Skeleton for Mini-ITX boards: Mini Skeleton-90 is also available.

Latest BIOS can be downloaded from ASUS Service Site (ASUSTeK Computer Inc.)

The trick for the Asus SABERTOOTH X79 is to name the file correctly! the support of Asus did not understand my question and was not able to answer under which filename you have to save the bios, hence this small post.

When you’ll download the latest bios version from ASUS Service Site (ASUSTeK Computer Inc.), you’ll end up with a file name like this one: SABERTOOTH-X79-ASUS-0906.ROM for example

Rename the file to SABERX79.ROM before copying it on the USB disk or it wont be recognized by the bios flashback function.

How did I find this? brute forcing the file name by trying something like 25 filename and having luck : ridiculous.

Other than definitely a great mainboard and quite cheap if you consider the number of features: USB3, SATA-6, UEFI Bios, PCI 3.0

This is the kind of geek stuff that put a big smile on my face when I read it... a portable ladtop capable of listening 300 wireless networks and hacking WEP keys in 5 minutes....

A small security firm has made a portable computer that is capable of scanning 300 networks simultaneously. Dubbed the "Janus Project", the computer also has a unique "Instant Off" switch that renders the captured data inaccessible. At first glance, the Janus computer looks like a ladtop , but Williams said it is much more powerful than that. Inside the rugged yellow case sits a mini-computer motherboard powered by a 1.5 GHz VIA C7 processor and an Acer 17" LCD screen. Ubuntu 6.0 Linux runs the eight Atheros a/b/g Gold mini-PCI cards which continuously scan wireless networks. [....] In addition to scanning for wireless traffic, Williams says the computer can break most WEP keys very quickly by focusing all eight wireless cards on the access point. Using a combination of common utilities like airreplay, airdump and aircrack, Willams said, "When I use all 8 radios to focus in on a single access point, [the WEP key] lasts less than five minutes." However, he added that some retail wireless access points will "just die" after being hit with so much traffic...  read more here

Apple Reality distortion field is now getting more and more ridiculous…

“Apple revolutionized the telecommunications industry in 2007 when it introduced
the wildly popular iPhone, a product that dramatically changed the way people view mobile
phones.  Reviewers, analysts and consumers immediately recognized the iPhone as a “game
changer.”  Before the iPhone, cell phones were utilitarian devices with key pads for dialing and
small, passive display screens that did not allow for touch control.  The iPhone was radically
different.  In one small and lightweight handheld device, it offered sophisticated mobile phone
functions, a multi-touch screen that allows users to control the phone with their fingers, music
storage and playback, a mobile computing platform for handheld applications, and full access to
the Internet.” from http://www.apple.com/pr/pdf/110415samsungcomplaint.pdf

Apple seems to not understand anymore the concept of evolution

• Smaller and lighter is something that any industry is doing all the time
• Better embedded CPU –> lead to faster experience and more capabilities(browser)
• Development of cell phones network –> internet is slowly possible
• Better battery technology –> lead to Bigger screen
• Cheaper euh no Apple is not well known for that

The order has change in the top 3 of the most evil companies…Apple is now number one!

1. Apple
2. Oracle
3. Microsoft

In a public legal brief (PDF), Apple offers numerous design alternatives that Samsung could have used for its smartphones and tablets to avoid infringing on Apple's patents.

From the PDF

"Alternate tablet computer designs include: overall shapes that are not rectangular with four flat sides or that do not have four rounded corners; front surfaces that are not completely flat or clear and that have substantial adornment; thick frames rather than a thin rim around the front surface; and profiles that are not thin relative to the D’889 or that have a cluttered appearance."

The simple combination of these things shouldn't be protected! Tablet are sharing by the same design limitations and there are a limited number of ways to solve the problems. Touch screens devices are going to be rectangular, with few buttons and most of the space dedicated to the screen!

Multi touch and pinch to zoom years before Apple copy it!

Microsoft and Perceptive Pixel Inc. (PPI) today announced that they have entered into a definitive agreement under which Microsoft will acquire PPI, a recognized leader in research, development and production of large-scale, multi-touch display solutions.

Jeff Han shows off a cheap, scalable multi-touch and pressure-sensitive computer screen interface that may spell the end of point-and-click.

Who did copy what? looking at Apple’s Timeline it’s pretty clear:

• … was developed way before
• 2006 Perceptive Pixel Inc. (PPI)  demo
• June 29 2007 iPhone
• July 11 2008 iPhone 3G
• June 19 2009 iPhone 3GS
• June 24 2010 iPhone 4
• October 14 2011 iPhone 4S

From http://www.ted.com/talks/jeff_han_demos_his_breakthrough_touchscreen.html

I'm really, really excited to be here today, because I'm about to show you some stuff that's just ready to come out of the lab, literally, and I'm really glad that you guys are going to be amongst the first to be able to see it in person, because I really, really think this is going to change -- really change -- the way we interact with machines from this point on.

Now, this is a rear-projected drafting table. It's about 36 inches wide and it's equipped with a multi-touch sensor. Now, normal touch sensors that you see, like on a kiosk or interactive whiteboards, can only register one point of contact at a time. This thing allows you to have multiple points at the same time. They can use both my hands; I can use chording actions;I can just go right up and use all 10 fingers if I wanted to. You know, like that.

Now, multi-touch sensing isn't completely new. I mean, people like Bill Buxton have been playing around with it in the '80s. However, the approach I built here is actually high-resolution, low-cost, and probably most importantly, very scalable. So, the technology, you know, isn't the most exciting thing here right now, other than probably its newfound accessibility. What's really interesting here is what you can do with it and the kind of interfaces you can build on top of it. So let's see.

So, for instance, we have a lava lamp application here. Now, you can see, I can use both of my hands to kind of squeeze together and put the blobs together. I can inject heat into the system here, or I can pull it apart with two of my fingers. It's completely intuitive; there's no instruction manual. The interface just kind of disappears. This started out as kind of a screensaver app that one of the Ph.D. students in our lab, Ilya Rosenberg, made. But I think its true identity comes out here.

Now what's great about a multi-touch sensor is that, you know, I could be doing this with as many fingers here, but of course multi-touch also inherently means multi-user. So Chris could be out here interacting with another part of Lava, while I kind of play around with it here. You can imagine a new kind of sculpting tool, where I'm kind of warming something up, making it malleable, and then letting it cool down and solidifying in a certain state.Google should have something like this in their lobby. (Laughter)

I'll show you something -- a little more of a concrete example here, as this thing loads. This is a photographer's light box application. Again, I can use both of my hands to interact and move photos around. But what's even cooler is that if I have two fingers, I can actually grab a photo and then stretch it out like that really easily. I can pan, zoom and rotate it effortlessly.I can do that grossly with both of my hands, or I can do it just with two fingers on each of my hands together. If I grab the canvas, I can kind of do the same thing -- stretch it out. I can do it simultaneously, where I'm holding this down, and gripping on another one, stretching this out like this.

Again, the interface just disappears here. There's no manual. This is exactly what you expect, especially if you haven't interacted with a computer before. Now, when you have initiatives like the $100 laptop, I kind of cringe at the idea that we're going to introduce a whole new generation of people to computing with this standard mouse-and-windows-pointer interface. This is something that I think is really the way we should be interacting with machines from this point on. (Applause) Now, of course, I can bring up a keyboard. And I can bring that around, put that up there. Now, obviously, this is kind of a standard keyboard,but of course I can rescale it to make it work well for my hands. And that's really important, because there's no reason in this day and age that we should be conforming to a physical device. That leads to bad things, like RSI. We have so much technology nowadays that these interfaces should start conforming to us. There's so little applied now to actually improving the way we interact with interfaces from this point on. This keyboard is probably actually the really wrong direction to go. You can imagine, in the future, as we develop this kind of technology, a keyboard that kind of automatically drifts as your hand moves away,and really intelligently anticipates which key you're trying to stroke with your hands. So -- again, isn't this great?

Audience: Where's your lab?

Jeff Han: I'm a research scientist at NYU in New York.

Here's an example of another kind of app. I can make these little fuzz balls. It'll remember the strokes I'm making. Of course I can do it with all my hands. It's pressure-sensitive, you can notice. But what's neat about that is, again, I showed you that two-finger gesture that allows you to zoom in really quickly. Because you don't have to switch to a hand tool or the magnifying glass tool, you can just continuously make things in real multiple scales, all at the same time. I can create big things out here, but I can go back and really quickly go back to where I started, and make even smaller things here.

Now this is going to be really important as we start getting to things like data visualization. For instance, I think we all really enjoyed Hans Rosling's talk, and he really emphasized the fact that I've been thinking about for a long time too: we have all this great data, but for some reason, it's just sitting there. We're not really accessing it. And one of the reasons why I think that is, is because -- we'll be helped by things like graphics and visualization and inference tools, but I also think a big part of it is going to be starting to be able to have better interfaces, to be able to drill down into this kind of data, while still thinking about the big picture here.

Let me show you another app here. This is something called WorldWind. It's done by NASA. It's a kind of -- we've all seen Google Earth; this is an open-source version of that. There are plug-ins to be able to load in different data sets that NASA's collected over the years. But as you can see, I can use the same two-fingered gestures to go down and go in really seamlessly. There's no interface, again. It really allows anybody to kind of go in -- and, it just does what you'd expect, you know? Again, there's just no interface here. The interface just disappears. I can switch to different data views. That's what's neat about this app here. There you go. NASA's really cool. They have these hyper-spectral images that are false-colored so you can -- it's really good for determining vegetative use. Well, let's go back to this.

Now, the great thing about mapping applications -- it's not really 2D, it's kind of 3D. So, again, with a multi-point interface, you can do a gesture like this -- so you can be able to tilt around like that, you know. It's not just simply relegated to a kind of 2D panning and motion.Now, this gesture that we've developed, again, is just putting two fingers down -- it's defining an axis of tilt -- and I can tilt up and down that way. That's something we just came up with on the spot, you know; it's probably not the right thing to do, but there's such interesting things you can do with this kind of interface. It's just so much fun playing around with too. (Laughter)

And so the last thing I want to show you is -- you know, I'm sure we can all think of a lot of entertainment apps that you can do with this thing. I'm a little more interested in the kind of creative applications we can do with this. Now, here's a simple application here -- I can draw out a curve. And when I close it, it becomes a character. But the neat thing about it is I can add control points. And then what I can do is manipulate them with both of my fingers at the same time. And you notice what it does. It's kind of a puppeteering thing, where I can useas many fingers as I have to draw and make --

Now, there's a lot of actual math going on under here for this to control this mesh and do the right thing. I mean, this technique of being able to manipulate a mesh here, with multiple control points, is actually something that's state of the art. It was just released at Siggraph last year, but it's a great example of the kind of research I really love: all this compute power to apply to make things do the right things, intuitive things, to do exactly what you expect.

So, multi-touch interaction research is a very active field right now in HCI. I'm not the only one doing it; there are a lot of other people getting into it. This kind of technology is going to let even more people get into it, and I'm really looking forward to interacting with all you guysover the next few days and seeing how it can apply to your respective fields. Thank you.(Applause)

All my latest blue screens of Windows 7 Ultimate 64 bits, 48 inches of blue wallpapers :-)

The Blue Screen of Death (officially known as Stop error, also known as BSoD, bluescreen, or Blue Screen of Doom) is a colloquialism used for the error screen displayed by some operating systems, most notably Microsoft Windows, after encountering a critical system error that can cause the system to shut down to prevent irreversible damage to its integrity. It serves to present information for diagnostic purposes that was collected as the operating system issued a bug check. [WikiPedia]

23 Juli 2010  MEMORY_MANAGEMENT blue screen of death

20 June 2010 KERNEL_DATA_IN_PAGE_ERROR blue screen of death

16 June 2010 UNKNOW blue screen of death

 

8 June 2010 BAD_POOL_CALLER blue screen of death

Do i get more and more blue screens?

YES, the first 5 months none, (installed Windows 7 in november 2009), now i get some…2 per months, maybe it’s time to reinstall the whole operating system :-)

Would I still recommend Windows 7  64 bits?

Yes still,  if you want to start Eclipse with 2GB of RAM, you have no other choice! except switching to Linux or Mac :-)
