Papert has also been widely known for focusing on the impact of new technologies on learning in general and in schools as learning organizations in particular. To this end, Papert used Piaget's work in his development of the Logo programming language whilst at MIT. He created Logo as a tool to improve the way that children think and solve the problems. A small robot called the "Logo Turtle" was developed and children used it to solve problems. A main purpose of the Logo Foundation research group is to strengthen the ability to learn knowledge. Papert insists a language or program that children can learn -- like Logo -- does not have to lack functionality for expert users.

Processing RAW files in Linux
Decoding is not an easy thing to do, because the light-sensitive points on an array (CMOS or CCD) do not sense colors, only light intensity (the light is filtered separately for each primary color), which means creating a “mosaic” image in the camera. The camera then has to process the image in such manner, as to provide each pixel with full information about the color (based on the neighboring monochromatic points). It is also necessary to correct the white balance, and some cameras also adjust the contrast and saturation. The electronic hardware in the camera has thus a plenty of complex operations to accomplish after the shutter button is pressed.

windows software freeware defrag jkdefrag howto harddisk defragmentation

JkDefrag
38 more annotations...
- JkDefrag-3.36.zip
  
  Download for Windows 2000/2003/XP/Vista/2008
  479kb
- JkDefrag shows a high-detail map of the harddisk,
  refreshed 3 times per second. Bottom-left of the window is the beginning of
  the harddisk. The colors used are:
  
  Black: empty
  Green: regular files, unfragmented
  Dark green: spacehogs, unfragmented
  Yellow: fragmented
  Red: unmovable
  White: busy
  Pink: MFT reserved zone (NTFS only)
  Gray: in use by unknown data
- Tip: Cleanup old junk from your harddisk before running JkDefrag
- Tip: Reboot before running JkDefrag
- Tip: Stop your real time virus scanner before running JkDefrag
- Tip: Move the swap file to another volume, reboot, defragment, and move the
  swap file back.
- Tip: Package unused files with a packager such as
  7-zip
  .
  The packagefile not only takes less harddisk space, but will also
  defragment and optimize much faster than the individual files.
- Tip: The first partition on a harddisk is significantly faster than
  other partitions. Try to use other partitions only for "SpaceHog" data
- Tip: If you have 2 physical harddisks (of the same speed), then place the
  pagefile on the first partition of the second harddisk.
- Defragmentation and optimizing will not only make a harddisk faster, but also
  lengthen it's life span. The disk will have less work to do and therefore have
  less wear and tear.
  Secondly, the sorting optimization strategies (see the "-a" option) will
  refresh all the magnetic data on your harddisk.
- On most harddisks the beginning of the harddisk is considerably faster than the
  end, sometimes by as much as 200 percent
- JkDefrag classifies files into 3 zones: directories (zone 1), regular files (zone 2),
  and SpaceHogs (zone 3).
  Directories are perhaps the most accessed data on disk, so zone 1 is
  placed at the beginning of the harddisk.
- Sorting the files on your disk can give you even more speed. There are several
  sorting strategies to choose from (see the "-a" options). These are all very slow
  and intended for occasional use only.
- Windows reserves a percentage of the disk for the MFT (Master File Table),
  but can place normal files there if the rest of the disk is full.
  The files will remain there, even when there is enough space again.
  JkDefrag looks for files in the MFT reserved space and moves them to
  normal diskspace, making the reserved space available again for the MFT.
- For example:
  
  JkDefrag.exe -a 7 -d 2 -q c: d:
- -a N
  
  The action to perform. N is a number from 1 to 11, default is 3:
  
  1 = Analyze, do not defragment and do not optimize.
  
  2 = Defragment only, do not optimize.
  
  3 = Defragment and fast optimize [recommended].
  
  5 = Force together.
  
  6 = Move to end of disk.
  
  7 = Optimize by sorting all files by name (folder + filename).
  
  8 = Optimize by sorting all files by size (smallest first).
  
  9 = Optimize by sorting all files by last access (newest first).
  
  10 = Optimize by sorting all files by last change (oldest first).
  
  11 = Optimize by sorting all files by creation time (oldest first).
- items
  
  The items to be defragmented and optimized, such as a file, directory,
  disk, mount point, or volume, including removable media such as
  floppies, USB disks, memory sticks, and other volumes that behave
  like a harddisk.
  Wildcards '*' and '?' are allowed to select a set of files.
  If the item contains a space then it must be enclosed in double-quotes.
  Some examples:
  
  JkDefrag C: D:
  JkDefrag f:\*.log D:\MySQL\Data\*
- Sorted optimization
  
  All the sorting optimizations WILL CREATE FRAGMENTS. This is by design, it is not a bug.
  For more info see the Frequently Asked Questions.
  
  These sorting optimizations are for incidental use once in a while.
  They take a lot of running time and data movement because they rewrite all
  the data on the disk.
  The strategies vacate a small area on disk and then fill it up again with the
  files in the selected order.
- Sort by name: very good for fast program starting. The files used by a
  particular program will be very close together on disk.
- Sort by size: placing all the small files together at the beginning of the disk
  will dramatically reduce the average file seek time.
- Sort by last access: files that have not been accessed in a while are
  probably unimportant and are best sorted to the back.
- Sort by last change: placing files together that change a lot (for example
  databases and log files) will speed up regular operation of the system.
- Sort by creation time: The oldest files on the disk are likely to be
  important system files, for example used when Windows is booting.
- What is the best defragmentation/optimization strategy for me?
  My advice for all computers is to run JkDefrag once with the "-a 7" optimization
  (sort by name), and from then on automatically every day with the default "-a 3"
  fast-optimize option.
- Windows reserves some space for expansion of the MFT, default is 12.5% of
  the volume size.
  This space is counted by Windows as free space because it can/will be used for
  regular files when the rest of the volume is full. JkDefrag cannot move files
  into this space, only out of ("reclaim MFT reserved space").
- A file can only be defragmented if there is a gap on disk big enough to hold
  the entire file. There may be plenty of free space, but what is needed is a
  single big gap. In these cases JkDefrag will try to reduce the number of
  fragments in the file by using the biggest gaps available.
- Assuming a harddisk speed of 40 megabytes per second, then reading 100
  gigabytes of data will take 100000 / 40 = 2500 seconds (42 minutes).
  But JkDefrag has to do a lot more
- How do I defragment unmounted volumes?
  
  Specify the VolumeName on the JkDefrag commandline. For example:
  
  jkdefrag \\?\Volume{35683226-d2c4-11dc-9740-806e6f6e6963}\
  
  Note: To get a list of all volumes on the computer enter "mountvol" in a command
  prompt window.
- Why use this defragger instead of the standard Windows defragger?
- Directories are moved to the beginning of the disk.
- Reclaims MFT reserved space after disk-full.
- Can defragment very full harddisks.
- Can defragment individual directories and files.
- The Microsoft defragmentation API on Vista can defragment and move the MFT, but
  JkDefrag cannot use this capability yet.
  
- JkDefrag Portable
  Packaged as a portable app (runs from a CD, or a USB disk), with an easy to use GUI.
- HD Tune
  Measure your harddisk and discover how much faster it is at the beginning than at
  the end. Can also monitor the temperature of your harddisk and scan for surface errors.
- DiskView
  by Microsoft TechNet (formerly Sysinternals)
  Small utility that shows which file is using a particular location on the
  harddisk. Use this if you are wondering which file JkDefrag could not move.
  The utility takes a while to start up, because it has to analyze
  all files one by one, but it's a very nice little utility nevertheless.
  HDview
  Similar utility as DiskView, by Alexander Freudenberg. Much faster and for NTFS only.

software power cpu howto help

Some people write software that lets you choose different power profiles depending on whether you're on AC or battery. Typically, one of the choices lets you reduce the speed of your processor when you're on battery. This is bad. It is wrong. The people who implement these programs are dangerous. Do not listen to them. Do not endorse their product and/or newsletter. Do not allow your eldest child to engage in conjugal acts with them. Doing this will reduce your battery life. It will heat up your home. It will kill baby seals. The sea will rise and your car will float away. If you are already running it, make sure that it always sets your cpufreq governor to ondemand and does not limit the frequencies in use. Failure to do so will result in me setting you on fire[4].

api open standards oss computers software

working with such APIs is like being a bespoke tailor - you have to measure them carefully, and cut your code exactly right to fit in with their shapes, and the effort is the same for every site you have to deal with
Conversely, when a site adopts a standard format for expressing their data, or how to interact with it, you can put your code together once, try it out on some conformance tests, and be sure it will work across a wide range of different sites

- Putting together such standards, like HTML5, OpenID, OAuth or OpenSocial or, for Dave's example of reviews, hReview, takes more thought and reflection than just replicating your own internal data structures, but the payoff is that implementations can interoperate without knowing of each others' existence

linux ubuntu software install compile howto cvs subversion

By default, Ubuntu does not come with the tools required. You need to install the package build-essential for making the package and checkinstall for putting it into your package manager. These can be found on the install CD or in the repositories, searching in Synaptic Package Manager or the command-line apt-get:
```
sudo apt-get install build-essential checkinstall
```
And since you may want to get code from some projects with no released version, you should install the packages cvs and subversion.
```
sudo apt-get install cvs subversion
```
Most of the software you'll generally want comes from released tarballs. These are just compressed archives with extensions like .tar.gz or .tar.bz2 — they are just like .zip files on Windows or .sit on MacOS X, if that analogy helps you. If the program you want to install comes in this form, you should move it into the /usr/local/src directory we made in Step 1 and extract it by right-clicking on the file and selecting Extract Here, or by using the command line: If your tarball is a .gz, extract the files with the command:

OpenGL 3 & DirectX 11: The War Is Over - Print

www.tomshardware.com/review_print.php - Preview

software opengl directx ms microsoft linux oss opensource open source development

To fully understand the controversy that surrounded the announcement of OpenGL 3, we have to go back a few years to 2002. At that time, as we said in our introduction, OpenGL was losing ground. Up until that point, DirectX had simply copied the capabilities of OpenGL. This time, however, SGI’s API had been overtaken. With DirectX 9, Microsoft introduced support for a high-level shader language, HLSL, and OpenGL had nothing to compare. It is important to note that OpenGL’s origins lie with IRIS GL, an API initially created by SGI to expose the functionality of its hardware. For a long time, ATI and Nvidia simply followed SGI’s rendering model, which meant that OpenGL was especially well-suited to the makers’ cards even before they were released. But with the introduction of shaders, the new GPUs moved away from the traditional rendering pipeline.
certain points of implementation weren’t decided on in time, and that in parallel, a lot of people felt that it had become urgent to enable OpenGL support for the latest GPUs. So the plan was modified in order to extend OpenGL 2 to include Direct3D 10 functionality.
2 more annotations...
- According to Carmack, OpenGL 3’s falling short of what it was supposed to be is mainly the fault of certain CAD software developers who weren’t really favorable to Longs Peak. They were afraid of problems with compatibility and their applications due to the disappearance of certain older functions. That version was tacitly confirmed by Lichtenbelt: “ During the Longs Peak design phase, we ran into disagreement over what features to remove from the API...The disagreements happened because of different market needs...We discovered we couldn’t do one API to serve all..”
- Microsoft is largely to blame. After hyping the merits of its API for several years before it was actually available, surely it had to expect a certain amount of discontent when gamers realized that the actual product didn’t really change much for them. Add to that the fact that the new API was written exclusively for Vista, and it was enough to generate animosity toward what had been presented as nothing less than a small revolution. As for developers, things were even more complicated. By associating Direct3D 10 and Vista, Microsoft greatly limited the number of existing computers that would be able to run a game using the API.
