Jeroen turns 42 today

Posted by jpluimers on 2011/04/29

is a remarkeble number, and forty-two is what Jeroen turns today.

Jeroen won’t panic, as he lives on a mostly harmless planet, and plans to live for quite a while longer.

Don’t forget your towel today!

How to: Configure Express to accept remote connections – SQL Server Express WebLog – Site Home – MSDN Blogs

Posted by jpluimers on 2011/04/28

when developing embedded Windows software, SQL Express can be a good option.

However, embedded usually means you can’t install a big tool-set (like SQL Server Management Studio or SQL Server Profiler) on the target system.

So if you want to monitor or profile it, you need remote access to your SQL Express instance (usually SQLEXPRESS).

The How to: Configure Express to accept remote connections – SQL Server Express WebLog article on the SQL Server Express WebLog and the KB article How to configure SQL Server 2005 to allow remote connections explain the details.

This is a short summary:

  1. Enable TCP/IP using the SQL Server Configuration Manager
    (you can do this using the registry too)
  2. Enable the SQL Browser using the SQL Server Configuration Manager
  3. Open your firewall for the TCP ports (more difficult) or SQL Server process (easier)
  4. Enable mixed mode login authentication from the registry:
    HKLM/Software/Microsoft/MSSQLServer/MSSQLServer/LoginMode = 1 integrated security, 2 mixed.
  5. Make sure that SA can login, and give it a strong password using this in SQLCMD:
    ALTER LOGIN sa ENABLE
    ALTER LOGIN sa WITH PASSWORD=’Som3StrongP@assword’
  6. Restart the SQL Server Service
  7. Start the SQL Browser Service

Finally connect to your SQL Express server by using SQLCMD:

SQLCMD –S machinename\SQLEXPRESS –Usa –PSom3StrongP@assword

Some notes on BASS (re)encoding and tagging audio files

Posted by jpluimers on 2011/04/27

When (re)encoding files through BASS:

  1. always make sure you either have RAW PCM format source; decode back from anything else back to RAW PCM if you have compressed sources; this BassEncoder.EncodeFile thread explains why.
  2. not all of the BASS encoder classes support tagging with artist/title; use external tools for that; this message explains which encoders (partially) support tagging.
  3. often it is not possible to find the encoder that both encodes the audio in the quality level you want, and supports the tagging you want, so you definitely need to look at the above mentioned tagging tools.
  4. if you want to play lots of files in random succession, it is wise to calculate ReplayGain and apply it: it makes your files sound equally loud: note this is not wise if you want to play full albums, but is wise for playing random tracks. This ReplayGain thread can provide you with a start.
    You can do gain correction with BASS, or opt for external gain tools on RareWares.org.

Tortoise SVN Global Ignore Pattern for Delphi and Visual Studio

Posted by jpluimers on 2011/04/26

Since I use (among others) both Visual Studio and Delphi, I changed the Tortoise Global Ignore Pattern to be this:

Debug lib *.identcache *.local *bin *obj RECYCLER Bin *.user *.suo *.dcu __history ModelSupport_* *.rsm thumbs.db *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store

The bold portion is what I changed when compared to the original one:

*.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store

Input from Tortoise SVN Global Ignore Pattern for Visual Studio (which also included some of the Delphi patterns), and this Stackoverflow question (that indicated the patterns are case sensitive).

alias to have Unix list command ‘ls’ output numerical chmod permissions (via Stack Overflow)

Posted by jpluimers on 2011/04/25

Though I use Linux and Cygwin often, the discrepancy between permissions in chmod and ls still strikes me.

I mean: after all these years, does the *nix world still want newbies to learn the octal notation of file permissions and do the math themselves? Come on!

Bsaically, you can use the stat command to show the octal permissions next to the filename (so you can apply them with chmod), but sometimes it is handy to have both the chmod and ls versions next to each other.

For showing both, this awk script comes in handy.

I slightly modified it to use ls -al instead of ls -l, and condense it on one line:

ls -al|awk '{k=0;s=0;for(i=0;i<=8;i++){;k+=((substr($1,i+2,1)~/[rwxst]/)*2^(8-i));};j=4;for(i=4;i<=10;i+=3){;s+=((substr($1,i,1)~/[stST]/)*j);j/=2;};if(k){;printf("%0o%0o ",s,k);};print;}'

If you want to have it in your .bashrc or .bash_aliases, then you need to escape the double quotes and dollar signs:

alias "lsmod=ls -al|awk '{k=0;s=0;for(i=0;i<=8;i++){;k+=((substr(\$1,i+2,1)~/[rwxst]/)*2^(8-i));};j=4;for(i=4;i<=10;i+=3){;s+=((substr(\$1,i,1)~/[stST]/)*j);j/=2;};if(k){;printf(\"%0o%0o \",s,k);};print;}'"

It shows me a listing like this:
$ lsmod
0200 total 47
0755 drwxr-xr-x+ 1 jeroenp None 0 Apr 11 14:00 .
1777 drwxrwxrwt+ 1 jeroenp root 0 Apr 11 09:21 ..
