After a update of my wife’s MacBook today everything seemed ok until she decided to try to start Microsoft Word – and it turned out none of the Office program worked.

A number of lines appeared in the console window more or less like this :

kernel[0]: shared region: 0x4204c80:#9#0: addr=0x70000000, size=0x17000, file_offset=0x2d000, prot=(5,5)

I tried all the normal things, and in the end trawled the internet. I came across a long running forum discussing just this here :

http://discussions.apple.com/thread.jspa?threadID=1039074&start=135&tstart=0

and decided to download the 10.4.10 combo updater from Apple and run this.

Fortunately this soled all her problems!

This looks like a decent (free) irc client for OsX :

Colloquy: IRC, SILC & ICB Client:

Traditionally, chat clients on the Mac have been anything but glamorous. Colloquy is an advanced IRC, SILC & ICB client which aims to fill this void. By adhering to Mac OS X interface conventions, Colloquy has the look and feel of a quality Mac application.

This blog has excellent reviews of all the major irc clients for mac’s under OSX – it’s really good:

The Joy of Apple » Blog Archive » A Review of the Top IRC Clients for OS X:

Are you stuck trying to decide which IRC client is the best for you? To help make the job easier for you, I have reviewed all of the most popular IRC clients for OS X here, listing their pros and cons and including screenshots. Some years ago I wrote a fairly popular IRC client for Windows called Bersirc. It included scripting, plugins, and all the basics you would expect from an IRC client (as well as beating most other clients, including mIRC to multiple-servers).

I found some more JOTI information here – it’s a few years old, but better than nothing

As I started using Snak (the irc client), I quickly found that there was one major thing missing for someone that uses as many windows as i (courtesy of VirtueDesktops), namely notification of new messages through Growl.

But a quick “google” later – and I found a script here – dropped it into Snak’s script folder, and I’m ready to try it!

So after starting to use a irc client, I started looking at how to set up a irc server on one of our Macs.

And yet one more time macPorts came to the rescue, I found a chat about ngircd here – and off I went.

With MacPorts installed:

port install ngircd

and 10 minutes later I have a fully functioning irc server ready. Just edit /opt/local/etc/ngircd.conf with sensible defaults, and the server was ready to go.

In the runup to JOTI (Jamboree on the Internet) I have been trying out irc clients for the Mac, and the one I have ended up with is snak – a excellent client with all the normal features you’d expect from a IM client.

Version 1.1 of varnish (the reverse proxy) was just released (20/7/2007), and according to the release notes this was changed :

Changes between 1.0.4 and 1.1

varnishd

• Readability of the C source code generated from VCL code has been improved.

• Equality (==) and inequality (!=) operators have been implemented for IP

addresses (which previously could only be compared using ACLs).

• The address of the listening socket on which the client connection was

received is now available to VCL as the server.ip variable.

• Each object’s hash key is now computed based on a string which is available

to VCL as req.hash. A VCL hook named vcl_hash has been added to allow VCL

scripts to control hash generation (for instance, whether or not to include

the value of the Host: header in the hash).

• The setup code for listening sockets has been modified to detect and handle

situations where a host name resolves to multiple IP addresses. It will now

attempt to bind to each IP address separately, and report a failure only if

none of them worked.

• Network or protocol errors that occur while retrieving an object from a

backend server now result in a synthetic error page being inserted into the

cache with a 30-second TTL. This should help avoid driving an overburdened

backend server into the ground by repeatedly requesting the same object.

• The child process will now drop root privileges immediately upon startup.

The user and group to use are specified with the user and group run-time

parameters, which default to nobody and nogroup, respectively. Other

changes have been made in an effort to increase the isolation between

parent and child, and reduce the impact of a compromise of the child

process.

• Objects which are received from the backend with a Vary: header are now

stored separately according to the values of the headers specified in

Vary:. This allows Varnish to correctly cache e.g. compressed and

uncompressed versions of the same object.

• Each Varnish instance now has a name, which by default is the host name of

the machine it runs on, but can be any string that would be valid as a

relative or absolute directory name. It is used to construct the name of a

directory in which the server state as well as all temporary files are

stored. This makes it possible to run multiple Varnish instances on the

same machine without conflict.

• When invoked with the -C option, varnishd will now not just translate the

VCL code to C, but also compile the C code and attempt to load the

resulting shared object.

• Attempts by VCL code to reference a variable outside its scope or to assign

a value to a read-only variable will now result in compile-time rather than

run-time errors.

• The new command-line option -F will make varnishd run in the foreground,

without enabling debugging.

• New VCL variables have been introduced to allow inspection and manipulation

of the request sent to the backend (bereq.request, bereq.url, bereq.proto

and bereq.http) and the response to the client (resp.proto, resp.status,

resp.response and resp.http).

• Statistics from the storage code (including the amount of data and free

space in the cache) are now available to varnishstat and other

statistics-gathering tools.

• Objects are now kept on an LRU list which is kept loosely up-to-date (to

within a few seconds). When cache runs out, the objects at the tail end of

the LRU list are discarded one by one until there is enough space for the

freshly requested object(s). A VCL hook, vcl_discard, is allowed to inspect

each object and determine its fate by returning either keep or discard.

• A new VCL hook, vcl_deliver, provides a chance to adjust the response

before it is sent to the client.

• A new management command, vcl.show, displays the VCL source code of any

loaded configuration.

• A new VCL variable, now, provides VCL scripts with the current time in

seconds since the epoch.

• A new VCL variable, obj.lastuse, reflects the time in seconds since the

object in question was last used.

• VCL scripts can now add an HTTP header (or modify the value of an existing

one) by assigning a value to the corresponding variable, and strip an HTTP

header by using the remove keyword.

• VCL scripts can now modify the HTTP status code of cached objects

(obj.status) and responses (resp.status)

• Numeric and other non-textual variables in VCL can now be assigned to

textual variables; they will be converted as needed.

• VCL scripts can now apply regular expression substitutions to textual

variables using the regsub function.

• A new management command, status, returns the state of the child.

• Varnish will now build and run on Mac OS X.

varnishadm

• This is a new utility which sends a single command to a Varnish server’s

management port and prints the result to stdout, greatly simplifying the

use of the management port from scripts.

varnishhist

• The user interface has been greatly improved; the histogram will be

automatically rescaled and redrawn when the window size changes, and it is

updated regularly rather than at a rate dependent on the amount of log data

gathered. In addition, the name of the Varnish instance being watched is

displayed in the upper right corner.

varnishncsa

• In addition to client traffic, varnishncsa can now also process log data

from backend traffic.

• A bug that would cause varnishncsa to segfault when it encountered an empty

HTTP header in the log file has been fixed.

varnishreplay

• This new utility will attempt to recreate the HTTP traffic which resulted

in the raw Varnish log data which it is fed.

varnishstat

• Don’t print lifetime averages when it doesn’t make any sense—for instance,

there is no point in dividing the amount in bytes of free cache space by

the lifetime in seconds of the varnishd process.

• The user interface has been greatly improved; varnishstat will no longer

print more than fits in the terminal, and will respond correctly to window

resize events. The output produced in one-shot mode has been modified to

include symbolic names for each entry. In addition, the name of the Varnish

instance being watched is displayed in the upper right corner in curses

mode.

varnishtop

• The user interface has been greatly improved; varnishtop will now respond

correctly to window resize events, and one-shot mode (-1) actually works.

In addition, the name of the Varnish instance being watched is displayed in

the upper right corner in curses mode.

Another good news story for a slow day – from my old hometown Trondheim in Norway.

Two blind friends went to a concert, where the bouncers confiscated their canes (they were unable to bring their guide dogs) – as they were unable to prove that they were blind (enough) to need the canes……

The original story is in Norwegian.

Vakt beslagla blindestokkene :

To blinde famlet rundt i blinde på konsert på Lerkendal:

Vakt beslagla blindestokkene

De to blinde venninnene Elisabeth Brattland (30) og Diana Johnsen (29) ble fratatt blindestokkene sine p̴ konsert p̴ Lerkendal. РVi har aldri opplevd maken, sier de to til adressa.no
