Dies ist die Displayplatine der AEG Öko Lavamat 6725 (deutsche Waschmaschine, Baujahr 1995). Schaltplan gibts leider keinen, und die Notizen gehören nicht dazu.
Auf den Chips steht HCF4094BE, und GR2 ist eine Zenerdiode mit 5.5V. TS17 ist ein NPN-Spannungsregler. Im Fall eines Komplettausfalls empfiehlt es sich, zuerst die Dioden (und den TS17) an der linken Seite zu prüfen.
How to get a fast connection between a Macbook Air and a Windows PC
If you ever tried to transfer files over Wifi between a Mac and a PC, you were probably horrified by the usual transfer speed (about 30kb/s). How can you use the full transfer speed of USB 2.0 and still have a comfortable setup (e.g., folder sharing or internet sharing)?
First, a Macbook Air doesn’t have an ethernet adapter. So, a USB gigabit ethernet adapter is required (it will only reach about ~320MBit, due to USB speed limitations). You can get the original Apple adapter, but it’s slower, not very reliable, and there are cheaper alternatives. To stay compatible with existing drivers, you want anything with an ASIX chipset. I got the Digitus DN-3022 for 21€.
After you connected the two computers with an ethernet cable (a simple patch cable will suffice), your Mac should say that a new network device has been found. Go to the network preferences and fill in this:
The IP address can be chosen freely, but 192.X.X.X or 10.X.X.X ranges are highly recommended. Leave the last three fields empty, or you’ll use the internet connectivity on your Mac!
Next, you want to enable Internet sharing.
On your Windows PC, loosely follow this configuration. The most important thing is that the gateway is set to your Mac’s IP address, and that the DNS points to your wireless router.
Unison and directory changes
I love Unison. It’s open-source, it’s cross-platform compatible, it’s reasonably fast, it never ever destroyed my data, it has just enough verbosity to make it practical, and it’s even more intelligent than rsync. It even occasionally detects when a folder name has changed (instead of deleting the mirrored folder and copying everything over again). Long story short - I use it for all my backup requirements.
However, there is one crucial problem (two actually, but changing drive names are definitely Windows’ fault - and since I mounted every single drive into designated folders, everything’s okay). As I said, the problem:
If you have a carefully crafted Unison backup profile, and you change anything (name or location) about one of the source folders, Unison will present you with two options. Either you’ll get a proper warning that it doesn’t know this folder, or it’ll think one of the two folders is just empty (and delete everything in the other one, if you aren’t wary).
What if you just discovered that your massive movie folder doesn’t fit on your drive any more, but you’d like to: 1. keep it in one piece, 2. keep it in the backup routine and 3. not do all the hour-long indexing-crap all over again? Apparently, you can find the preference files for each profile, and it may be possible to convince Unison with a so-called rootalias that one of its folders have changed. However, I’ve literally tried every possible syntax combination for this property, and it just doesn’t work as advertised.
So, the easy solution is to create a hardlink. Just pretend to Unison that the folder is still there, and it’ll run just as well as before. The command on Windows would be mklink -j (don’t try to use D, because that’s a symlink), and the Windows calls these junctions. Of course, this solution is quite near to cheating, and will break in quite a few (predictable) circumstances, but it works just fine because Unison is oblivious to hardlinks. If you figure out how to set the rootalias correctly, I’m open for suggestions.
carfolio just collects the cold hard facts, and leaves the soft data (price, mileage, reliability) to other sites. But boy, do they have a lot of cold hard facts.
They have absolutely every spec about (almost) every car ever produced. Want to know the power-to-weight of this ‘32 Maybach, or the specific wind resistance of that rare SUV? No problem. And that’s what I love them for.
The new iTunes Backup structure (from iTunes 9.2 onwards) relies on a very intransparent organization. You can find the following files in the usual folder (User\AppData\Roaming\Apple Computer\MobileSync\Backup\UniqueBackupID\):
- info.plist - general metadata about the backup
- manifest.mbdb - a list of the iPhone folder structure (semi-readable)
- manifest.mdbx - presumably the same list, but compressed
- manifest.plist - List of third party applications and settings
- status.plist - more metadata
- …and thousands of files, each named in a 13-byte hex cifer.
The most advertised solution to browse these files would be the iPhone Backup Extractor (or similar “user-friendly” products), but it provides very limited functionality (only restores six files, and doesn’t leave them intact) and costs a lot of money.
For the more advanced user, there’s the Open Source project iPhoneBackupBrowser. The module mbdbdump (here’s the source code, and here’s a mirror) parses all the entries from manifest.mbdb and shows you the original file location on the phone.
User interface:
- Chose a backup (this relies on an existing info.plist in the correct folder)
- Double click on an entry in the second list (most likely you want to see the “System” entry)
- The third list shows all the filenames in their original location. Drag and drop individual files into a new folder. You’ll still get the cryptic name, but at least you know now how the files are supposed to be called. Be sure to have any copy enhancers turned off - for example, TeraCopy would give a nondescriptive error with this procedure.

People with different types of bodies tend to think differently in predictable ways, even about abstract ideas that seem far removed from bodily experience. Right- and left-handers implicitly associate positive ideas like goodness and honesty more strongly with their dominant side of space, the side on which they can interact with their environment more fluently, and negative ideas with their non-dominant side. This suggests a role for motor experience in shaping abstract thoughts. Yet, previous evidence is also consistent with an experience-independent account. Here we show that right-handers’ tendency to associate ‘good’ with right and ‘bad’ with left can be reversed due to both long- and short-term changes in motor fluency. Among stroke patients who were right-handed prior to unilateral cerebrovascular accident (CVA), those with left-hemiparesis (following right CVA) associated good with right, but those with right-hemiparesis (following left CVA) associated good with left, like natural left-handers. A similar pattern was found in healthy right-handers whose right or left hand was temporarily handicapped in a laboratory training task. Motor experience influences judgments of good and bad, overriding any predispositions due to natural handedness. Even highly abstract ideas depend, in part, on how people interact with the physical world.
Zelda: orchestration
I’m currently re-arranging the game music from Zelda: Link’s Awakening into an orchestral version. Because the GameBoy is limited to three tracks at a time, one has to be a bit creative with adding new instruments and chords.
But it’s worth the effort - the results sound amazing.
Automatic sorting of photos in folders
Photos from any cheap digital camera come in one big folder, including all the images you have made. If you want your photos in separate folders which indicate the capture date, you probably will need this script.
The script “imagefolder.py” scans all JPGs and TIFs in its directory for their EXIF metadata. If a capture date is present, the photo will be moved in a subfolder in the format YYMMDD*. If the folder doesn’t exist, the folder will be created.
If no EXIF is present, the file attributes will be used. This is only a fallback solution and is not guaranteed to work correctly.
You’ll need:
Python 2.6 or greater
Exifpy (put it in the Python folder)
imagefolder.py (put it in the image folder)
Mirror
Currently my script is Windows only (uses creation date and Windows file system commands), but could be adapted to MacOS or Unix fairly quickly.
* If you want to change your folder format, search for strftime in the script and adapt the following string according to the python time guidelines.
