Reducing the size of your Windows.edb (Search) and DataStore.edb (Update) databases
Posted by jpluimers on 2017/01/30
Windows Search: Windows.edb
If you use Windows Search (I don’t: I use Everything by VoidTools), your Windows.edb can grow ridiculously large. It is a single file, though it appears to be in two places because there is a symbolic link from C:\Users\All Users to C:\ProgramData :
C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb
C:\Users\All Users\Microsoft\Search\Data\Applications\Windows\Windows.edb
This is how to reduce its size:
How to offline defrag the index
- Change the Windows Search service so that it does not automatically start. To do this, run the following command in cmd.exe:
sc config wsearch start= disabled- Run the following command to stop the Windows Search service:
net stop wsearch- Run the following command to perform offline compaction of the Windows.edb file:
esentutl.exe /d %AllUsersProfile%\Microsoft\Search\Data\Applications\Windows\Windows.edb- Run the following command to change the Windows Search service to delayed start:
sc config wsearch start= delayed-auto- Run the following command to start the service:
net start wsearch
Notes:
- I did not perform the last 2 steps as I’ve kept Windows Search disabled.
- If you want to reduce the size of the
C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\directory:- Before step 1, choose what kind of Windows Search indexing options you want
- Between step 3 and 4, delete the directory
Windows Update: DataStore.edb
Windows Update uses the same database structure and is a single file:
C:\Windows\SoftwareDistribution\DataStore\DataStore.edb
This is how I reduced its size:
net stop wuauserv net stop bits esentutl.exe /d C:\Windows\SoftwareDistribution\DataStore\DataStore.edb net start bits net start wuauserv
Talking about Windows Update: you might also want to Clean Up the WinSxS Folder

DIY pick and place machine from parts of scanner, inkjet printer, DVD player and vaccuum pump – Open Theremin – Urs Gaudenz
Posted by jpluimers on 2017/01/30
Urs Gaudenz manufactures Open.Theremin kits using his do it yourself pick and place machine which he built from low cost scanner, ink jet printer, DVD player mechanics and some Arduino controlling. Even his solder oven is Arduino controlled!
This is months of work showing a work flow in a 11 minute youtube video. Well done!

apache links for log formats, log kinds, etc
Posted by jpluimers on 2017/01/27
Am I the only one who thinks Apache logging configuration is a mess? Especially when you look at the templates shipping with various *nix distros?
Files like vhost-ssl.template and vhost.template using different ways of logging for the same thing make me cringe. This apart from ordering of configuration between the files being different, some lines doing tab-indent and others doing space-indent and non-matching spaces-per-tab settings between the files.
The apache wiki examples have different issues.
How can you expect mere mortals getting vhost configuration right when the provided templates are so bad?
Given the move towards SSL/TLS, mortals like me won’t easily get it right either.
A few things I think that should be done:
- For vhosts, standardise on vhost_combined, not combined.
- Favour CustomLog over TransferLog.
- Make a choice: either log in a Catch All log file, or put each vhost log in different files (now it’s different for the SSL and normal template).
- If using separate log files per vhost, then include a vhost reference in the log filenames.
- Add a vhost_ssl_combined in addition to ssl_combined.
- Document ErrorLog in the same place as CustomLog and TransferLog.
- Provide templates for combining regular and SSL vhost configs which currently is hard.
- Make timestamps in logging formats the same. They are different between ssl_combined and the others. Don’t you hate that? What happened to ISO-8601?

Since I was talking about security anyway…. this is a nice toy for breaking open laptops or desktops when the administrator forbade the installation of software, or you want software on it executed. This is often the case with company devices, e.g. the laptops which are supplied by banks to their 3rd party suppliers. Outsourcing is cool, remember?
This is a computer on a stick which can run a Linux kernel. In combination with some USB gadget kernel modules, it can be configured to authenticate itself as any device. All you need to do is plug it in, and iterate by brute force through the device identifiers until you hit one which is accepted to be used. Store the statically linked software you want to install or run on the stick beforehand, and here you go. So if you ever need a SSH client on a “secure” Windows laptop… putty.exe FTW.

fixing a Mac home `brew update` that has permission errors (after that I could install plantuml)
Posted by jpluimers on 2017/01/26
I had this occurring on my system:
RetinaMBPro1TB:~ jeroenp$ brew update error: unable to unlink old 'Library/ENV/pkgconfig/10.11/libcurl.pc' (Permission denied) error: unable to unlink old 'Library/ENV/pkgconfig/10.11/libxml-2.0.pc' (Permission denied) error: unable to unlink old 'Library/ENV/pkgconfig/10.11/sqlite3.pc' (Permission denied) To restore the stashed changes to /usr/local run: 'cd /usr/local && git stash pop' Already up-to-date.
This is how I solved it:
RetinaMBPro1TB:~ jeroenp$ ls -al /usr/local | grep -w Library drwxr-xr-x+ 11 jeroenp admin 374 Mar 9 19:33 Library RetinaMBPro1TB:~ jeroenp$ sudo chown -R $USER /usr/local/Library/ Password: RetinaMBPro1TB:~ jeroenp$ brew update To restore the stashed changes to /usr/local run: 'cd /usr/local && git stash pop' Updated Homebrew from d32996d to 638d755. ==> New Formulae ... ==> Updated Formulae ... ==> Renamed Formulae ... ==> Deleted Formulae ... RetinaMBPro1TB:~ jeroenp$
The above solution is based on major python problems · Issue #48301 · Homebrew/homebrew
After that, I could install plantuml (which requires java, just so you know) so now I can create SVGs from it locally:
plantuml -tsvg PSO.network-diagram.PlantUML.txt
Note I had to edit the formula so it installs plantuml-8037 or higher (the git version back then installed plantuml-8031) as it fixed a namespace bug. Since plantuml releases often, be prepared to do some version fiddling.

Coding width – via “Is it common to print out code on paper?” – Programmers Stack Exchange
Posted by jpluimers on 2017/01/25
I don’t often read code, but when I do, I print it.
For I a very long time, I’ve been formatting code until about 130 characters width and recently remembered out why:
… remember printing in landscape allowed 132 characters.At Uni, I used to regularly print my code on green bar paper…
Source: Is it common to print out code on paper? – Programmers Stack Exchange
It got back memories of working on VT102 terminals and Hercules Graphics Cards adapters doing VAX-VMS (FORTRAN and Pascal) and DOS (Turbo Pascal) programming. The VT102 could do 132 columns (the VT52 only 80) and it was no coincidence that most HGC could do 132 columns as well.
Printing was usually on green-bar paper (in Dutch “zebra-papier”) which was 132 columns wide in landscape form on most line printers.

Some notes and links on hacking a Philips TVs TCP ports
Posted by jpluimers on 2017/01/25
In my case this is about a Philips 42PFL7676H TV, but this likely applies to many Philips TVs from the 2009-2012 era.
According to nmap, these ports are open:
PORT STATE SERVICE REASON VERSION
1925/tcp open unknown syn-ack
2323/tcp open 3d-nfsd? syn-ack
49153/tcp open upnp syn-ack Philips Intel UPnP SDK 1.4 (Philips Smart TV; UPnP 1.0; DLNADOC 1.50)
TCP port 1925 is actually implementing the jointSPACE REST API over HTTP which has some nice documentation (also locally on your TV).
PCremote implements this and is easy to install: just download (or git clone) the html locally or to a web-server and try it, or even easier: browse to the www.netdata.be/tv site. You can even use it on your Raspberry Pi. There is also support for jointSPACE it in agocontrol.
Two nice threads about it from the Philips support forum:
TCP port 2323 seems to be the voodooport which should enable you to do DirectFB Voodoo.
Jean-Marc Harvengt (software engineer at Philips) showed a nice demo (see video below) on using VooDoo. I wish he had published the source code.
TCP port 49153 also hosts an HTTP server. The base URL I could find information about is 192.168.71.115:49153/nmrDescription.xml It seems that nmrDescription.xml has to do with DLNA and upnp.
Later on I found that my brothers 32PFL7675H TV should also support JointSPACE, but that it had to be activated:
AFTER upgrading to the new firmware, jointSPACE NEEDS TO BE ACTIVATED by entering the following digits sequence while watching TV (WatchTV activity): “5646877223”
Source: jointSPACE TVs Developers
Before activation, only port was open 49153. After that, port 2323 was open as well. But the www.netdata.be/tv app doesn’t work on this TV. This does work however: Philips MyRemote – Android Apps on Google Play
