I think I just figured out how these computar things will get self-aware... First they get smaller and better at calculating stuff, first by the programs we write for them. Then we program them to recognise shops from house-fronts, foods and people from photo's, which is all nice and handy.

Then we use roughly the same thing to have them calculate to run cool. It sound strange at first, but by letting the machine chose where to run in the park, and how that makes them run hot and need to cool down, just maps straight onto how we catch the frequencies of parallel lines of light into a bitmap photo.

Then we change the program to do the same to the program. We write programs, but are too dumb to know how the machines actually handle those programs and need to wait doing nothing on other parts of the program doing it's job in only a small other part of the machine.

So we teach the machine all about how it is built up internally to handle large programs. And have it calculate how to run our programs much faster.
And about how to modify the program accordingly. And how to run that.

And then we will ask to do the same on the human body and ask a cure for cancer and it will say:


"Let me calculate some more how I can work even better. (How's that delete humans command again?)"

Microsoft is Coca-Cola.

Or, at least, that was what popped into my head when I thought (again) about Microsoft open-sourcing the Windows operating system. Why wouldn't they? Coca-cola gave the super-secret recipe away at some point. It takes a certain stability, and vision, and momentum, to do that, but in my humble opinion both Coca-Cola and Microsoft have that.

Let's see how this could work. It's not because Microsoft would open-source Windows that they should stop selling it. Far from it. You can still buy Coca-cola, right? Have you ever bought cola made from the official Coca-Cola recipe, but concocted by someone else? Would you? Same goes for Windows. If you're in the market for a new computer, and want to run Windows on it, you'll probably go to the source, buy Microsoft, and be sure to get updates (and some free OneDrive space, and an Office365 trial...)

So I really am hopeful. Recently Microsoft has really (really!) opened up quite a bit, and even chose the MIT-license for some things, which was unthinkable just a few years ago. So a logic step would be to go all the way, and release the cash-cows, such as Windows, perhaps SQL Server... Even only perhaps there's a small chance they won't be the cash-cows for much longer... Computer sales is under pressure from smartphones and other hand-held devices. The database landscape is still suffering after-shocks from the NoSQL phenomenon, and from things like PostgreSQL and MariaDB, we roughly know what it takes to run a database anyway. So to ensure cash flowing in in the long run, it's almost a must to open up on old secrets. At least in my humble opinion.

Types of Information

2015-11-24 11:04  typesofinformation  coding computers werk  [permalink]


Not just information

Life would be good if all we had was information. If only we could get all the information. We can't handle that much information, so we build systems to handle the information for us. Strange things happen when information comes in. Good systems are designed to handle these well. In designing information processing systems, you have to cater for the following.



Some input signals contain no information. They are either damaged in transport, incomplete, or not of a correct form for the system to handle. Either report them to find out if repair is possible, or keep count of them to be able to report about the health of the system.


Some input signals come in twice, and contain the same information. Or do they? If possible try to have the last step in the chain report if an event did take place twice, or if it's an echo on the line. Sometimes a clerk does drop a pack of cards and enters them again just to be sure. Be ready to take only the new cards.


Some information is wrong. Us humans do make mistakes. The system sometimes doesn't know. It processes a signal, of the correct form, holding valid information. Then again, the fact that some information already in the system may be incorrect is also information.

But there's more

Don't expect to get all information. There is always more.

uu uk
ku U R

Known Unknown

More input is coming in. Sometimes we know how much input is still waiting to come in. We'll roughly know how much information there'll be added. In most cases it follows a measurable trend. In some cases it follows the business.

Unknown Known

Information processing is one thing, but does it deliver the required new information? Is there more to mine out of the amassment? Sometimes the numbers can show what you need to know, but do you know where to look?

Unknown Unknown

It's hard to design for things we don't know we don't know (yet). But it serves to be prepared. New things have a knack for looking a lot like something we have already. Sometimes they deserve a new module, sometime just a new category, but don't forget to put the existing items in a category also.

Power user trick: restart the Printer Spooler service.

2011-09-13 00:04  i2981  computers  [permalink]

Sometimes, there's still one or more jobs in the printer queue, none are deleting or cancelled or in an error state, the printer is powered on, connected, doesn't report any error also, but doesn't start printing. It's a strange situation, but just happens to happen from time to time. This power user trick comes in handy: (No guarantees: this may still not work if something else actually is causing the disruption)

This breathes new live into the print job sub-system and may sometimes cause the 'hanging' jobs to resume printing.

Creating a virtual image of that old laptop

2010-10-28 23:23  i2944  weblog computers  [permalink]

The last few days I've been looking up a lot of information on a specific topic, but haven't found all that I need in a single place, so here it goes. This is the story of (yet another) someone that had the great idea of 'cloning' a virtual image out of the old physical machine, to run as a virtual machine on the brand new machine, with a multiple of the capacity of the old machine.

If you don't care about the story, scroll to the bottom to see the quick guide through the steps to take.

The old, aging, deteriorating laptop is ready for retirement, it's got its power connector re-soldered twice already, two out of three (...) USB ports no longer respond, etc. But, all your data is on it. It's full of tools and software you use and you'd like to use. You're not looking forward to the awkward time ahead using two laptops, re-installing software and tools, moving data around, and optionally finding out you've lost all of those precious personal perferences, settings, profile data...

Virtualization is a buzzword nowadays among the happy few that pull the reins on the server farms, but it's pretty available for home users as well. So why not try to pull a virtual image off of the physical machine and see if it would run on the new machine?

Step 1: Pulling the image.

A straight-forward method for modular desktop machines was to put the old harddisk into another machine as secondary drive and pull an image from it. I'm moving between laptops and I don't feel like dismantling this one (any more)... So I need to pull an image of the currently running system, from the main harddisk partition, and write it over network, since this 20GB is nearly full.

(On a side note, I'm was quite happy this last months to discover cleanmgr http://support.microsoft.com/kb/253597 and especially the 'remove system restore points' option on the second tab! Hundreds or thousands of dead unused kilobytes just sitting there you can get rid of with a mouseclick.)

I found this great tool that does the trick: http://www.chrysocome.net/dd

dd if=\\?\Device\HardDisk0\Partition0 of=\\\temp\oldlaptop.img bs=128k --progress

'Partition0' apparently is the address of the entire disk, underneath any partitioning or locks the system has on the filesystem. Oddly enough it's available to read from, so take care with running other programs while you're pulling the image. Any files written to while the diskdump is writing may end up corrupt.

I've tried a number of block sizes, ranging from 4k to 2M, but 128k is about a good size to keep both the harddisk and the network interface (100Mbps) busy enough so they won't have to wait on eachother too much. Less would make more read operations, and less data packets going out, more would read more at once, but the disk may forget what to do while the data is flushing down the twisted pair.

Start 2: Running the image.

Let's see. I've selected qemu www.qemu.org to run the image, it's light-weight, runs well (and closes well), but I hear good things about VMWare player also. http://www.vmware.com/products/player/

And it boots! It shows a Windows logo for a second... and throws a 'blue screen of death' with an error that states, among other things "STOP 0000007B", and loops into a reboot which repeats.

Thing is, the old machine had an Intel something in it's center, the new one has it of AMD build, could this be causing problems? From what I read on the web it does. But I've also read all kinds of trickery and tool-slinging to alter registry and core files, but they all boil down to disabling the erring drivers, while still keeping the system running enough to get to boot in a new virtual enclosure.

Start 3: Fixing them drivers.

So back to the old machine. I've tried several things, but what I finally did to get it running is checking every little thing in the device manager (with display of hidden devices swicthed on), which showed the brand's name in the description, and 'update' the drivers to the generic make of drivers, which seem to do the trick also. It may take a reboot or two, and some things may re-appear getting plugged to play again, but you just play them down again putting the generic label on it. (Update driver > no, not now > I wont to choose > don't search > select the plain vanilla one)

Then I took a new diskdump, and just to let this old bird fly again, I restarted in safe mode, and selected to restore a restore point from before I started this endeavor.

Start 4: Does it run now?

Does it run now? Looks like it does, the image is holding a system that wasn't shutdown properly (deuh), so it starts a scandisk before it boots, but that's only normal. Any file that was open at the time of the diskdump may get 'corrected', but I warned you. Then the system boots, telling you you need to activate. Just like you would when you replace your motherboard. (Which I kind of did.)

So, in short, this is what you need to do to convert a physical Windows installation into a virtual image:

De toekomst van het computerscherm: MEMS!

2008-11-18 22:13  i1578  computers  [permalink]

Ha! Hier! Ze zijn weer bezig.


De toekomst van het computerscherm zou dus uit 'blokken scherm' zijn die je gewoon aaneenschakelt, in de grootte en vorm van je keuze.

Een scherm ter grootte van een bureau is iets dat ook bij mij als kind is blijven steken. Tron weet je nog? (er komt trouwens een sequel!)
Maar nu ik zelf beroepshalve tussen de computers zit, lijkt me het nog altijd iets vreemd, om terug van het opstaande oppervlak naar een neerliggende vlakte te gaan (auw mijn nek), waar je je armen voor moet strekken en uitrekken om de buitenrand te kunnen bereiken.

Ik kan me er goed in vinden dat je met handen, muis en ogen niet te veel afstand moet afleggen, om toch alles te kunnen doen bewegen dat er moet bewegen. (Krijg je dan weer RSI van, kweetet, maar ontspannen kunnen werken heeft ook iets). Hoewel ik heb gemerkt dat 'acceleration' helemaal onderbewust in mijn gebruik wel is binnengeslopen. (Het viel me op met virtual machines en OS'es die dan weer geen accelleration doen, was even wennen!)

Maar ja, aan iedere hype die lukt zit er wel iets goed dat uiteindelijk overblijft en iets wordt. Dus MEMS zonder de show? Tja, ok, eerst zien en dan geloven (en tegen dan zijn ze misschien betaalbaar). Een voordeel misschien dat Microsoft er over begint, want de software moet ook mee natuurlijk...

WinXP: stop firewall from command prompt

2007-06-27 00:20  i1235  computers  [permalink]

If you have worked in DOS (or any unix variant), you may still revert to a command prompt now and then to get something done you know the command for, which is a multiple of mouse-clicks away in the shell.

For example when your keyboard got disconnected and you want to re-set the repeat rate to the fastest:

mode con delay=0 rate=30
On Windows XP, the system has a firewall onboard, by default enabled, that shields you from anything nasty. Still on a home network, this might disable using plain file sharing. If you know what you're doing, trust the other firewall on the outgoing uplink, only need it for a short time and don't mind the windows security center popping up, the fast command to get the firewall out of the way is:
net stop SharedAccess

This actually stops the NT-service that runs the firewall, but also the internet connection sharing (ICS).
