I used this Ubuntu NUT article as a basis for installing NUT on Ubuntu Server 9.04.
I did install it command-line ( apt-get install nut) and found you need to 'reboot' to have the new udev rule file run against the USB UPS.

Notes:
* (time consuming) Channel mapping in Seattle required watching all the TV station, then hitting the 'E' key to type in the station information (Callsign and number) as per schedulesdirect.org. Plus enabling that channel in my lineup in schedulesdirect.org.
* Ensure that the network is up before mythtv backend (otherwise the tuner is marked as down)

Often I find myself using the time machine to discover whether some new install is the problem or something it depends isn't responding as expected.
So you want something older than curl 7.16 out of the portage tree? Use the less than (<) symbol:
emerge -av "<net-misc/curl-7.16.0"
Last December after a significantly power outage, I purchased a Tripp Lite OMNI1000LCD USB UPS from Costco. I spent awhile integrating it with my Gentoo distro running on my home server. I found that Network-UPS Tools (NUT for short) was the best way to go. I would recommend them and their mailing list if you are interested in getting anything running -- I've been lurking on their mailing-list for 12 months now and it is one of the most helpful lists I've seen in my days.
Back in December of 2006, I had no choice but to get a development tree and compile it and integrate that with Portage (see old HOWTO link ). Today NUT version 2.2.0 is in the tree but all architectures are marked as in 'testing'. That is the tilde in front of them : ~alpha ~amd64 ~ppc ~sparc ~x86 ~x86-fbsd when you look at portage nut package . unmasking this package will be much easier than my last experience of integrating my own build in portage (overlaying).
I've been running on this 2.2.0 package for a couple months and I declare it seems good to me.
If you want to unmask it and test it yourself that is simple:
(1) add the following line to the file /etc/portage/package.keywords
=sys-power/nut-2.2.0 ~x86
This will allow you to install this package.
(2) emerge nut with the hal flag
USE="hal" emerge nut
(3) Configure NUT
- the OMNI1000LCD is working fine with the new usbhid-ups driver
Now that we've made this build, you can follow the steps at the wiki:
Gentoo HOWTO NUT (Network UPS Tools)
You'll get to start after the Install Software section. Yes, you'll need the usbhid-ups driver. I am pasting my last instructions with the appropriate substitutions for the OMNI1000LCD for NUT 2.2.0.
I added the bit about adding a MONITOR line to uspmon.conf. This is necessary for upsmon to work
Configuring
Go to /etc/nut . Open ups.conf. Add to this file every UPS you want to monitor. Mine looks like this:
# [powerware]
# driver = bcmxcp
# port = /dev/ttyS0
# desc = "Server, adsl, 3com"
Change the values to something that fit's your configuration better and save. If you have a USB connection to your UPS, your entry might look like
[OMNI1000LCD]
driver = usbhid-ups
port = auto
desc = "Tripp Lite OMNI1000LCD USB"
Open upsd.conf. This file contains access-policy to the UPS's you have.
To only allow the same computer to connect to them, the file should look like this:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1
ACCEPT localhost
REJECT all
The ACL-lines are used to add hosts. The syntax is ACL name IP. If the name is placed after ACCEPT connections from there are accepted, if it's placed under REJECT, connections are rejected. This sort of reminds me of a hosts.allow file?
Next open upsd.users. This file contains accounts for users who can make modifications. The following line grants access to the user server to everything. This isn't integrated with particular logins from my observation. So you can make-up a new user/pass and run with that. The only place one needs to remember this if you are setting properties through NUT on the UPS.
[server]
password = changeme
allowfrom = localhost
actions = SET
instcmds = ALL
upsmon master
Next take a look at upsmon.conf. This is the UPS Monitor configuration. A scan through this file is going to answer more questions than me writing about it. It is pretty simple, but the below three changes are all I needed to make.
1. in Gentoo, the nut package uses the 'nut' user, so ensure this is in there.
RUN_AS_USER nut
2. The UPS to monitor
MONITOR OMNI1000LCD@localhost 1 server changeme master
3. for those of us with a measly single UPS for our home network you'll need this line:
MINSUPPLIES 1
Next if you want look at upssched.conf too, it may be interesting if you want to schedule events. This will be useful if you want to automate something like "30 seconds after the power is out, send an email via SMTP." I currently am not interested in this
Finishing
Now, start the upsd and upsmon service:
/etc/init.d/upsd start
/etc/init.d/upsmon start
This should identify if there is some still wrong.
If nothing is wrong add them to the default runlevel
rc-update add upsd default
rc-update add upsmon default
If you didn't get any error when you started the services you seemed to configure it right. Else, have a look at the error output and think what might be wrong. One error I got was the permissions of the serialport, which is easy fixed with adding nut to the tty-group.
Testing
You'll be using tools upsc and upscmd
Test upsc and see if your UPS replies:
upsc yourupsname@yourupshost ups.status
specifically from above conf: upsc OMNI1000LCD@localhost ups.status
If you get "OL" (On Line) everything is working good (if it is on the line and not battery).
To see every command your UPS supports, type
upscmd -l OMNI1000LCD@localhost
A full status looks like the below.
#upsc OMNI1000LCD@localhost
battery.charge: 100
battery.type: PbAc
battery.voltage: 13.4
battery.voltage.nominal: 12.0
driver.name: usbhid-ups
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.2.0
driver.version.data: TrippLite HID 0.1 (experimental)
driver.version.internal: 0.30
input.frequency: 59.8
input.voltage: 117.2
input.voltage.nominal: 120
output.frequency.nominal: 60

ups.productid: 2005
ups.serial: 692195 B
ups.status: OL CHRG
ups.test.result: 0
ups.vendorid: 09ae
If you've typed that command and gotten a similar response you are on the winning side of this conf.

Last year I built a little tool that migrated blogs from LiveJournal to Blogger. It was aptly named lj2blogger. Today is the release of version 2.5
I've recently extended it to be able to move blogs from LiveJournal, Blogger, WordPress and publish to LiveJournal, Blogger, Windows Live Spaces, WordPress. This means you can move your blog to a new blog name or clone it.
Time to rename the tool, subsequently, it is now called Blog2Blog. Possibly further blogging systems will be integrated in later versions.
This is now a .NET 2.0 Application.
Download Blog2Blog (2.5.0.0 updated March 9, 2009)

We've identified a bug in the latest google feeds and client libraries. (http://groups.google.com/group/bloggerDev/browse_thread/thread/6fa01659eb21b0d for deep details)
Basically as a work-around, you need to put the blogger.com feed SOURCE-API-URL. To find this you will need to view the html source of your blog and look for the string that will contain "service.post" it will contain a URL like:
"http://www.blogger.com/feeds/*blog_id_number_here*/posts/default"
That is the URL you'll need for the SOURCE-API-URL or DEST-API-URL

Since many of you have likely hit this blog while looking HOWTO tether a blackberry on Linux, it would be kind of me to point you to somewhere you can do this. Thibaut posted a comment on my blog with a link, so I'll share it here.
I've not personally tried this, but this looks solid. Let me know how it goes out there.

Of the several million people who have purchased this phone, I may have been one of the few that wanted to import a Comma Separated Value (CSV) contact list into my Motorola RAZR V3xx cellular phone? Before handing over my Blackberry Pearl to my former company I had exported my contacts for importing once I got another mobile phone. A practical solution, right? After all who wants to re-enter 75 contacts through a mobile phone's interface?
This address book import turned out to be a little more challenging than it should have been. First off, Motorola provides an application to do all variety of communication to ones phone, for a price ($40). I've already paid for the phone and this didn't seem practical/economical for a single use.
Not my solutions
Hence I wandered the internet in search of an open-source solution. After stumbling across KMobilePhoneTools (linux), P2KTools (Windows), and P2K Commander (Windows). I found that I had spent a number of hours discovering the following tidbits:
To re-iterate some other posts, I use the Oregon Scientific WMR-968 weather station with the wx200d version 1.3 ( Sourceforge link ). One of the nice side-effects of the wx200d daemon is that it collects and stores the data in a text format at /usr/local/share/wx200d/. This is TAB separated format (TSV).
I didn't find a succinct definition of this TAB separated format file when searching for it, so here is with one line of data for context my extrapolation of it from the source file tab.c:
Time--TAB--Indoor Temperature--TAB--Outdoor Temperature--TAB--Indoor Humidity--TAB--Outdoor Humidity--TAB--Dew Point Indoor--TAB--Dew Point Outdoor--TAB--Barametric Pressure Indoor--TAB--Barametric Pressure Outdoor--TAB--Wind Gust Direction--TAB--Wind Gust Speed--TAB--Wind Direction--TAB--Wind Speed--TAB--Wind Chill--TAB--Rain Rate--TAB--Rain Total

Recent experience with the Apple Graphite AirPort Base station and the newest MS OS Vista found me googling without an answer. This is likely to be a rare combination these days, so it isn't a surprise to not have a solution out there. This is used for wireless modem sharing up my parent's (in-law) cabin where the cost of high-speed Internet is preventative.
The basic symptom was that the "Internet" wasn't functioning on the Vista machine. It could connect fine with the AirPort base station, but would get no further. Digging deeper it appeared that DNS was not functioning for the Vista machine. A little more digging and installing a separate copy of Vista using bootcamp for Mac confirmed it was reproducible.
Another step in the digging was to try an nslookup from a functioning machine -- note Windows XP, MAC OS X all work while simultaneously Vista does not.
Welcome to Darwin!
macpowerbookpro:~ user$ nslookup www.google.com
;; reply from unexpected source: 198.6.100.140#53, expected 10.0.1.1#53
;; reply from unexpected source: 198.6.100.140#53, expected 10.0.1.1#53
This seemed to be potentially at the root of the problem. I suspect that Windows XP/Mac OS X don't mind a response from a DNS server that it didn't ask. Vista is a bit more particular about it.
The temporary solution is to put the nameservers that your ISP has directly in the TCP/IP configuration of Vista (see image below). I admit there is probably a more complete solution, but this will keep one going until that is solved.

eclean can be your friend, it is a part of the gentoolkit. If you don't have the gentoolkit: emerge gentoolkit.
eclean can cleanup distribution files and packages. Because you are a regular emerge --sync, emerge --update --deep --ask world sort of person, you will likely be using disk space on all those old packages you have upgraded out of.
eclean distfiles
eclean packages
By default, eclean will protect all distfiles or binary packages corresponding to some ebuilds available in the Portage tree. This is the safest mode, since it will protect whatever may still be useful, for instance to downgrade a package without downloading its sources for the second time, or to reinstall a package you unmerge by mistake without recompiling it. Sure, it's also a mode in which your DISTDIR and PKGDIR will stay rather big (although still not growing infinitly). For the 'distfiles', this mode is also quit slow mode because it requiries some access to the whole Portage tree.
If you use the --destructive option, eclean will only protect files corresponding to some currently installed package (taking their exact version into account). It will save much more space, while still preserving sources files around for minor revision bumps, and binaries for reinstallation of corrupted packages. But it won't keep files for less usual operations like downgrading or reinstalling an unmerged package. This is also the fastest execution mode (big difference for distfiles), and the one used by most other cleaning scripts around like yacleaner (at least in its version 0.3).
Somewhere in the middle, adding the --package-names option when using --destructive will protect files corresponding to all existing versions of installed packages. It will allow easy downgrading without recompilation or redownloading in case of trouble, but won't protect you against package uninstallation.
In addition to this main modes, some options allow to declare a few special cases file protection rules:

I wished to fill my 1600X1400 monitor with my Gentoo VMWare image while in 'Quick switch' mode. However, the Fit Guest Now was grayed out. The reason? I needed to have vmware-user running (location for me: /usr/lib/vmware-tools/bin32/vmware-user). This is a tool in the VMWare tools. For VMWare tools installation see Install Gentoo on VMWare - VMWare Tools Section.

First off, the copy and paste is provided by VMWare Tools. VMWare Tools run under X Windows.
There are a number of articles out there describing how to do this for various flavors of VMWare; however, my experience has demonstrated that these work just fine for VMWare Server. I would worry not.
I found that with these instructions (HOWTO install Gentoo on VMWARE - installation of VMWARE Tool Section) and my original version of X11 R6.8 did not work out as well with driver module installation. Perhaps I was careless, but my solution was simply to upgrade to X Windows 7.2 - a seamless upgrade for me. Note to you: you may as well take a snapshot to allow a roll back.
I would recommend following the path of upgrading if you've not, insuring that you have in your make.conf: INPUT_DEVICES="keyboard vmmouse" VIDEO_CARDS="vmware". If you have/want to upgrade, as I did, follow these instructions: Migrating to Modular X HOWTO
After migrating to Modular X Windows 7.2 the VMWare tools launch automatically as I start X so copy and paste works seamlessly now.

In the quest to turn the data into information, many unique ideas as quickly formed when someone integrates two or more internet APIs these days. The marketing phrase Web 2.0 has been used to describe this, but it is news to me that someone has been managing the web releases from a configuration management standpoint.
What can be done with the 'Mashup'?
One of the advantages to having a Blackberry phone is the built-in ability to connect your PC/laptop to the internet via the phone. Now the hunt for free wireless connections while traveling has been made simple. No more of the questions (and the incessant googling that ensues to know for sure): does that hotel have free wireless? does this coffee shop have free wireless? Admission of internet addiction will be prevented and you (and I) can continue to remain in denial. Using this method I was able to achieve 120 Kbps downloads/ 60Kbps uploads in the Seattle area in March of 2007. It is not broadband speed these days, but it is better than 0 Kbps.

All UPS units tend to have an alarm (also known as the beeper) that sounds when the power is removed from the unit.

For instance see below. There is a nice background, overlayed with particular machine information.
This tool is for the admin and people with some windows know-how, but still I would love to wrap this tool up in a little installer to add a little more value like an example configuration file and allow it to use a config file and run on startup.
I am willing to bet that several people in the legal department at MS would not be willing to let me redistribute this tool with my own MSI. I am not willing to experiment and find out for sure.
Instead of an installer, I'll list out the minor steps that made this tool more valuable to me and provide the configuration as above for you to experiment with.
Configuration
To solve the always on storage, network attached storage [NAS], problem I choose to purchase the D-Link DSM-G600 device; in part because my tendency to stick with a the same hardware vendor. I may be naive and my demonstration is I believe that companies do more testing with their own hardware components than other hardware. The other part of the choice is that is a Gigabit NAS with a drive enclosure and with potential to plug in our external USB drives. The other, other part is that it is running Linux underneath.
I have the DSM-G600 revB and to demonstrate this last statement of it running a copy of embedded Linux, the following is the output of uname.
# uname -a
Linux NAS 2.4.21-pre4 #480 ¤ 4¤ë 28 11:21:43 CST 2006 ppc unknown
And it looks like the below image
First step is to understand 'fun_plug'. This is a script that is called after after the DSM-G600 boots, but the user has full control over it. It resides on the drive that you've put into the enclosure. For the full background: How to fun_plug . This concept is a big seller to me, it allows customization to your heart's content.
Starting to fun_plug
(reference: Wiki Page Howto fun_plug )
There are several way to get the fun plug script on the device. I would recommend connecting via Samba from a Linux host. Most importantly you'll save yourself the hassle of Unix vs. Windows linefeeds.
(1) You'll want your DSM-G600 booted (and a drive in the enclosure).
(2) From your linux host:
mount -t smbfs -o username=admin //
(3) Enter your password (the same as the web interface admin password).
(4) Execute:
touch /mnt/somedir/fun_plug
chmod 777 /mnt/somedir/fun_plug
(5) Customize fun_plug (open fun_plug up and do some customization) - See below
(6) Execute: umount /mnt/nas
Customization of fun_plug
There many customizations and the the limit only in your imagination . Several that seem worthy to mention are starting a telnet daemon, starting an itunes server, chrooting to a Gentoo distribution.

Sept 29, 2007 update - An updated tool (renamed to Blog2Blog)is available see this post for download. Regardless, We will keep this post and the download around for posterities sake. My advice would be to try the current blog2blog tool which has better error handling and updated functionality but the choice is yours.
As unknown surprise to the Blogger staff that picked my blog for the blog of note, I've been working on a tool to import LiveJournal blogs into Blogger. I may as well post this today for all of you incoming viewers. I wish I had something witty and amusing to say in addition, but words fail. I am certain I'll think of something in a couple of days, my mind just works that way -- slow and steady?
Like many good ideas, this one came from my wife who wanted to migrate from LiveJournal to Blogger. I looked around and didn't find a conversion tool after several attempts to Google it. Thus, as a good software developer I spent the time to learn several things and build a tool.
Note, I would say this is a Beta at this point. It works well for the scenarios I've run it through. Please feel free to comment/suggest improvements through the blog comments.
Download lj2blogger (1.5.0 updated Feb 12, 2007)
The above is a .zip with a Windows installer. To install unzip and double click on setup.exe.
After installing there is a small manual:
"LiveJournal2Blogger Manual.rtf" at C:\Program Files\Cooley Computing Inc\lj2blogger\doc (default location).
To save you the time of opening this file it is below.
LiveJournal2Blogger (lj2blogger)
Introduction
This tool migrates a blog from LiveJournal to Blogger. It uses the public API of LiveJournal and the public API of Blogger to extract data from Livejournal and create equivalent entries in a Blogger account with the appropriate date/time of the orignal entry.
Features
- Download Journal Entries from LiveJournal
- A simple read-only viewer of downloaded entries
- Publish Journal Entries to Blogger
* upload private entries (it will make them public)
* parse entries and wrap http:// entries with HTML to make them active links
- Delete ALL entries for a Blogger journal
- Save/Load journal entries to/from file.
Usage
The designed usage pattern is below. For issues please feel free to contact me at pcooley.newsgroups at gmail.com.
Download from LiveJournal
1. Enter username (e.g. user1).
2. Enter password (e.g. pass1).
3. Enter lj-url (the URL of the livejournal you wish to download): http://user1.livejournal.com.
4. (optional) if necessary modify the api-url of your journal. This is autopopulated with a typical value.
5. Press Fetch from LiveJournal Button.
View Entries (optional)
6. Press View Entries Button.
7. Use the Entry Number Dialog to change the entry being viewed.
8. When complete Press the upper right close window (the X).
Save Entries (optional)
1. Press Save Entries
2. Choose the filename, it is an XML file with the extension (*.J2B)
Note: once saved you can load these Entries without downloading from LiveJournal (use the Load Entries button)
Publish to Blogger
9. Enter username (e.g. user1).
10. Enter password (e.g. pass1).
11. Enter lj-url (the URL of the livejournal you wish to download): http://user1.blogspot.com.
12. (optional) if necessary modify the api-url of your journal. This is autopopulated with a typical value. (if you have a non-upgraded blog take note; for non-upgraded blogs you will need to update the api-url! To find the URL you will have to look at the page source of your journal. See below for more information)
13. (optional) select options you please; publish private entries and/or wrap http:// with <a href=”…”>.
14. Press Publish to Blogger Button.
15. Select the Entries you will to publish (defaults to all entries).
Further instructions (non-upgraded blogs):
For non-upgraded blogs you will need to find your feed URI.
-- To do this you will have to use your favorite browser and type in the URL of you blog (e.g. http://user1.blogspot.com)
-- Using your browser you will need to 'View Source'. This differs slightly between browsers.
-- In the source look for link rel="service.post" type="application/atom+xml" title="User1 (Atom 1.0)"
-- The api-url is the http:// location in the href
Additionally it is not possible to post to an old journal with a new 'google' integrated account (for those of you that have only partially upgraded all your journals). Addtionally the publish dates of your livejournal won't be regarded. This is part of the API limitation.
Known issues
• The Application is not multithreaded – The UI refreshes slowly while connected to LiveJournal/Blogger.
• Does not import/export comment
• found 01/02/2007 - defaults for api-url only work with upgraded blogs.
• There are connection problems with the XMLRPC interface to livejournal, but immediately retrying Fetch from Livejournal seems to connect sucessfully. Just try a couple of times. No harm should be done.
It appears today I made the blogs of note on blogger.com Blogs of Note. Incoming hits galore!
Happy Blogging

Getting a fine gift, A Kill-A-Watt device, from my Sister and Brother in-law last year meant I could measure the energy usage of my computer systems. Not necessarily a HOWTO article, but informative for those of us that obsess over numbers and metrics.
The Server Closet contains:
(1) Server (512MB/AMD Athlon(tm) XP 1600+)
(2) D-Link DI-724GU Router
(3) Comcast Cable modem (Motorola SB5120)
(4) Vonage Phone Adapter (Motorola VT1005V)
(5) Oregon Scientific WMR-968 Weather Station
- Note No Monitor
Power Usage:
1.34 Amp
125 Watts
2.95 KWH per day
My Primary System consists of:
(1) User System (1GB/Pentium 4 - 3.00GHz)
(2) Monitor 1 - Dell 2001FP 20" LCD
(3) Monitor 2 - Sony GDM-500PS CRT
(4) Sound - Yamaha Receiver RXV420, KLH Speakers and Subwoofer Model HTA-4906.
Power Usage:
3.06 A
300 - 400 Watts (depending on whether it is rendering in game or relaxing writing a document)
4.30 KWH per day
Our computer room is on a 15 Amp fuse and it now makes sense when my wife's computer system is on and she turns on an electric space heater my resulting trip to the fuse panel. Given the above, I now expect that fuse is probably even being lenient on us, given her system probably uses 3.0 Amps (identical system).
Keywords: computer, power usage, watts, how much power does my computer consume
The below documents my configuration of a Tripp Lite OMNI1000LCD USB UPS to communicate with Gentoo Linux (2.6.17-gentoo-r8 kernel) in my home network using NUT (Network UPS Tools). Note this is much easier in Dec 2007 - see new howto here
Plugged into the UPS :
(1) Linux Server (Older machine with AMD XP processor)
(2) D-Link DI-724GU Router
(3) Comcast Cable modem (Motorola SB5120)
(4) Vontage Phone Adapter (Motorola VT1005V)
(5) Oregon Scientific WMR-968 Weather Station
The average draw of those components is around 125 Watts (you have a Kill-A-Watt device don't you? Kill-A-Watt link). During my two simulated power outages it appeared that this UPS would power those components for ~30 minutes.
This UPS was purchased at Costco, so with that ease of distribution I suspect there might be more of you out there that may want to do this, so I'll write down my steps of configuration for Linux/Gentoo. Truth be told, maybe the key feature of the UPS verses others? The pretty Blue LCD display panel; even my wife attests to it aesthetic value.
Configuration took the better part of a day because, I didn't realize/admit the 2.0.4 version of NUT didn't support my Tripp Lite USB UPS. Once I use the development tree of NUT it was much easier. I hope to save you that time.
1. Ensure your kernel has hid support compiled into it
- in 'make menuconfig' select the '/dev/hiddev raw HID device support'
Device Drivers --->
USB support --->
<*> Support for Host-side USB
[*] HID input layer support
[ ] Force feedback support (EXPERIMENTAL)
[*] /dev/hiddev raw HID device support
2. emerge 'sys-power/nut'
Guess what? This, as of January 1, 2007, does not have the support in it for the Tripp Lite USB models (nut 2.0.4-r1 in portage). Following this, you will have to fetch the development trunk from the fine people on the NUT development team and create a Portage overlay. From this trunk, it runs great. I spent significant time starting the newhidups driver with the response No matching USB/HID UPS found and it appears 20 googles. It just doesn't work ;)
Note: Everything I know about Portage overlays I learned while watching a 'Cold Case' episode, so it isn't too hard. Kudos to portage.
3. Get the development trunk from Subversion. Don't have subversion in Gentoo? Me neither, but a simple 'emerge subversion', got me a running version.
mkdir ~/src/nut
cd ~/src/nut
svn co svn://svn.debian.org/nut/trunk
This will get the latest source for nut in a directory called trunk in your home directory ~/src/nut
4. Create a Portage Overlay for the development trunk source.
We will want to do this so that portage knows what we are up-to. Admittedly you can go straight for the compilation of the nut source and figure out all the configuration necessary to get it to run in Gentoo, but it was already all figured out for sys-power/nut-2.0.4.r1 so lets use that.
References:
HOWTO Create an Updated Ebuild
HOWTO Install 3rd Party Ebuilds (slightly less relevant in our case.)
a. Package the source:
in dir ~/src/nut
cp -r trunk nut-2.1.0
note: we are making up a nut version that follows the portage convention.
tar -cf nut-2.1.0.tar nut-2.1.0
gzip nut-2.1.0.tar
b. copy the source into the portage distribution tree
cp nut-2.1.0.tar.gz /usr/portage/distfiles/
c. Create an overlay directory and add it to your make.conf (I am presuming you have root like powers aren't I? Keep this in mind)
mkdir -p /usr/local/portage && echo 'PORTDIR_OVERLAY="/usr/local/portage"' >> /etc/make.conf
d. copy the existing ebuild for nut into your new Portage Overlay directory
make the dir: mkdir -p /usr/local/portage/sys-power/nut
copy it: cp -r /usr/portage/sys-power/nut /usr/local/portage/sys-power/nut
e. create the new ebuild file (copying from the latest ebuild).
cd /usr/local/portage/sys-power/nut
cp nut-2.0.4-r1.ebuild nut-2.1.0.ebuild
note: remember to name this the same as tar file above.
f. remove the ebuilds you don't need (I like clean)
for me it was: rm nut-2.0*
g. edit the ebuild. I removed a patch that probably isn't necessary in the development trunk.
nano -w /usr/local/portage/sys-power/nut/nut-2.1.0.ebuild
I removed line 46 that started with 'epatch'
5. Manually step thru the emerge steps with ebuild (slow and cautious). Ebuild is a lower level tool that emerge uses.
Note: I am only going to compile the driver I need, it isn't a default driver so I need to use the NUT_DRIVERS directive to ebuild system. Additionally when I didn't do this, one of the drivers in the development tree had a compile time error.
a. The digest:
NUT_DRIVERS="newhidups" ebuild /usr/local/portage/sys-power/nut/nut-2.1.0.ebuild digest
b. The unpacking (the unzips the tar file you created earlier):
NUT_DRIVERS="newhidups" ebuild /usr/local/portage/category/program/program-version.ebuild unpack
c. The compile
NUT_DRIVERS="newhidups" ebuild /usr/local/portage/category/program/program-version.ebuild compile
d. The installation
NUT_DRIVERS="newhidups" ebuild /usr/local/portage/category/program/program-version.ebuild install
Without the NUT_DRIVERS declaration I got:
/bin/sh ../libtool --tag=CC --mode=link i686-pc-linux-gnu-gcc -I../include -O2 -march=athlon-xp -pipe -Wall -Wsign-compare -o blazer blazer.o ../common/libcommon.a ../common/upsconf.o

6. Configure NUT
Now that we've made this build, you can follow the steps at the wiki:
Gentoo HOWTO NUT (Network UPS Tools)
You'll get to start after the Install Software section. Yes, you'll need the newhidups driver. I am pasting in the article with a couple of mods for my UPS posterity/consistency.
I added the bit about adding a MONITOR line to uspmon.conf. This is necessary for upsmon to work
Configuring
Go to /etc/nut . Open ups.conf. Add to this file every UPS you want to monitor. Mine looks like this:
# [powerware]
# driver = bcmxcp
# port = /dev/ttyS0
# desc = "Server, adsl, 3com"
Change the values to something that fit's your configuration better and save. If you have a USB connection to your UPS, your entry might look like
[OMNI1000]
driver = newhidups
port = auto
desc = "Tripp Lite OMNI1000LCD USB"
Open upsd.conf. This file contains access-policy to the UPS's you have.
To only allow the same computer to connect to them, the file should look like this:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1
ACCEPT localhost
REJECT all
The ACL-lines are used to add hosts. The syntax is ACL name IP. If the name is placed after ACCEPT connections from there are accepted, if it's placed under REJECT, connections are rejected. This sort of reminds me of a hosts.allow file?
Next open upsd.users. This file contains accounts for users who can make modifications. The following line grants access to the user server to everything. This isn't integrated with particular logins from my observation. So you can make-up a new user/pass and run with that. The only place one needs to remember this if you are setting properties through NUT on the UPS.
[server]
password = changeme
allowfrom = localhost
actions = SET
instcmds = ALL
upsmon master
Next take a look at upsmon.conf. This is the UPS Monitor configuration. A scan through this file is going to answer more questions than me writing about it. It is pretty simple, but the below three changes are all I needed to make.
On my routine of weekly updates to my gentoo installation I often encounter blocked packages in response to the command 'emerge --update --deep --ask world'
[blocks B ] mail-mta/ssmtp (is blocking mail-mta/postfix-2.2.2-r1)
This, until I became familiar with it, seemed confusing. My analysis, the order of this response is what tripped me up in combination with the temptation of speed reading. My interpretation was 'blocks mail-mta/ssmtp. Is blocking mail-mta/postfix-2.2.2-r1?' The parenthesis caused me to consider this as a separate thought. It is not and is my fault for confusing myself; And aside, I'd love for the parenthesis to be removed. That interpretive linguistics analysis aside on to the point.
Looking at the statement mail-mta/ssmtp is blocking mail-mta/postfix. The simple thing to do is to say, I don't need ssmtp let me remove it. The portage command:
emerge --unmerge 'mail-mta/smtp'
In summary it is the first item listed that is the 'blocking' package, that is what you want to remove.
Then try again with 'emerge --update --deep --ask world'
Of course the removal of something needed is a bad idea, so be careful.
An introduction to Portage: link
A simple portage Wiki page: Portage and Ebuilds
The man page: Portage Man page
The "best-known practices" for working with Portage: HOWTO_Use_Portage_Correctly

It appears to be low profile so I hadn't heard of this until a co-worker pointed out this MS Wiki where they are putting together a community to work on documenting patterns and practices.
Microsoft's Patterns and Practices Guidance Library
This is useful in two ways, (1) in defining some templates for creating better documentation. For instance there is a template for writing a Mini How To. It lists a number of good ideas to consider while writing a How To. (2) It provides documentation, an example How To: How To: Use Regular Expressions to Constrain Input in ASP.NET. Another example is they have checklists for instance they have a Web Services Security Checklist.
From my observation there are not necessarily 'deep' thoughts here. The statements all make sense, to the point that it seems like stating the obvious. The value is in that the thought have been persisted, collected and present in a clean and concise way. This means that in our haste to get a product out the door, we can walk through a relatively simple list to verify we didn't miss something obvious.
A good idea. I hope it continues to have contributions and a community is built around this.
A friend of mine sent me this link. This is really my blog, on steroids and then some. A community of people making howtos for Linux. Smart. I wish I thought of it :-).

I am definitely adding this to my resources. Maybe I should start to contribute.
Logparser can be your good friend if you have a large set of data (text form or otherwise) and you would like to summarize it. It can be used to analyze Microsoft’s Internet Information Server (IIS) logfiles, text based logfiles, XML files, Eventviewer data, Registry, Active Directory Objects, CSVs and more (see all the input formats at the end of blog entry).
The below is my documenting a howto use logparser with a number of examples. Most of the examples of IIS log parsing were not developed by me, rather there is a MS team that can be employed to do an IIS health check, these were the logparser SQLs they used.
Logparser to start
I recommend become familiar with:
logparser -h
In all truth all my needs have been answered in the command-line help. I may have googling for a solution, but the problem was solvable with careful reading.
Logparser and IIS logs.
Logpaser automatically reads the IIS header. In fact, I highly suspect that the reason for the tool’s existence began with the need to analyze IIS logs - the history and lore, I have not taken that much time to learn. I'll let you correct me?
Queries (examples):
updated March 2007 to add reverse DNS lookup, Referer URLs (sic), and Referer Summary (sic).
• Merge Multiple Log files
To consolidate log files into a single file.
logparser -o:IIS "select * into merged.log from ex*.log"
• A count of the Total Requests
logparser "select count(*) into IISLOG_TOTAL_REQ.csv from ex061023.log"
• How many unique clients
logparser "select count(distinct c-ip) into IISLOG_DISTINCT_CLIENTS.csv from ex061023.log"
• Top 20 URLs Hit
logparser "SELECT TOP 20 cs-uri-stem, COUNT(*) AS Hits INTO Analysis.csv from ex061023.log group by cs-uri-stem order by Hits DESC"
• Top 20 ASP pages Hit
logparser "SELECT TOP 20 cs-uri-stem, COUNT(*) AS Hits INTO Analysis.csv from ex061023.log where cs-uri-stem like '%%.asp' group by cs-uri-stem order by Hits DESC"
• Hit Frequency (how many hits per hour)
logparser "SELECT TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)), COUNT(*) AS Hit_Frequency INTO IISLOG_ANALYSIS_HIT_FREQ.CSV FROM ex061023.log GROUP BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ORDER BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ASC"
• Bytes per Extension
What is the percentage of the bytes served per extension-type?
logparser "SELECT EXTRACT_EXTENSION(cs-uri-stem) AS Extension, MUL(PROPSUM(sc-bytes),100.0) AS PercentOfTotalBytes INTO IISLOG_ANALYSIS_BYTES_PER_EXT.CSV FROM ex061023.log GROUP BY Extension ORDER BY PercentOfTotalBytes DESC"
• Top 20 Clients Hitting this server
logparser "SELECT top 20 c-ip AS Client_IP,count(c-ip) AS PageCount from ex061023.log to IISLOG_ANALYSIS_TOP20_CLIENT_IP.CSV GROUP BY c-ip ORDER BY count(c-ip) DESC"
• REVERSEDNS of Top 20 Clients Hitting this server (reversedns(...) is a long running function for obvious reasons)
logparser "SELECT top 20 c-ip AS Client_IP, REVERSEDNS(c-ip),count(c-ip) AS PageCount from ex061023.log to IISLOG_ANALYSIS_TOP20_CLIENT_IP_WITH_DNS.CSV GROUP BY c-ip ORDER BY count(c-ip) DESC"
• Referrer Host Names directing traffic to this server with count of pages referred (summary)
logparser "SELECT ReferringHost, count(*) AS TotalReferrals, Min(cs(Referer)) AS ExampleRefererURL USING CASE EXTRACT_TOKEN(cs(Referer),2, '/') WHEN null THEN 'NoReferer' ELSE EXTRACT_TOKEN(cs(Referer),2, '/') END as ReferringHost into IISLOG_ANALYSIS_REFERER_HOSTS.CSV FROM ex061023.log group by ReferringHost order by count(*) DESC"
• Referrer URLs directing traffic to this server (full report)
logparser "SELECT EXTRACT_TOKEN(cs(Referer),2, '/') as RefererHostName, cs(Referer) AS RefererURL, count(cs(Referer)) AS TotalReferrals into IISLOG_ANALYSIS_REFERERURLs.CSV FROM ex061023.log group by cs(Referer) order by count(cs(Referer)) DESC"
• Unique Clients per Hour
This is two separate SQLs.
1. logparser -o:CSV "Select TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) as Times, c-ip as ClientIP into IISLOG_ANALYSIS_DIST_CLIENT_IP.LOG from ex061023.log group by Times, ClientIP"
2. logparser -i:CSV "Select Times, count(*) as Count from IISLOG_ANALYSIS_DIST_CLIENT_IP.LOG to IISLOG_ANALYSIS_HOURLY_UNIQUE_CIP.CSV group by Times order by Times ASC"
• IIS Errors and URL Stem (Error code > 400)
logparser "SELECT cs-uri-stem, sc-status,sc-win32-status,COUNT(cs-uri-stem) from ex061023.log to IISLOG_ANALYSIS_ERROR_COUNT.CSV where sc-status>=400 GROUP BY cs-uri-stem,sc-status,sc-win32-status ORDER BY COUNT(cs-uri-stem) DESC"
• IIS Errors by hour (Error code > 500)
Can answer if the errors are load related
logparser "SELECT TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)), COUNT(*) AS Error_Frequency FROM ex061023.log TO IISLOG_ANALYSIS_ERROR_FREQ.CSV WHERE sc-status >= 500 GROUP BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ORDER BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ASC"
• Status Code distribution
logparser "SELECT sc-status, COUNT(*) AS Times from ex061023.log to IISLOG_ANALYSIS_STATUS_CODE.CSV GROUP BY sc-status ORDER BY Times DESC"
• Top 20 Longest time-taken (on average) pages
logparser "SELECT top 20 cs-uri-stem,count(cs-uri-stem) As Count,avg(sc-bytes) as sc-bytes,max(time-taken) as Max,min(time-taken) as Min,avg(time-taken) as Avg from ex061023.log to IISLOG_ANALYSIS_TOP20_AVG_LONGEST.CSV GROUP BY cs-uri-stem ORDER BY avg(time-taken) DESC"
• Top 50 longest requests
logparser "SELECT top 50 TO_LOWERCASE(cs-uri-stem),time,sc-bytes,time-taken INTO IISLOG_ANALYSIS_TOP50_LONGEST.CSV FROM ex061023.log ORDER BY time-taken DESC"
• Average Response time by Hour
logparser "SELECT TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)), avg(time-taken) INTO IISLOG_ANALYSIS_AVG_RESP_TIME.CSV FROM ex061023.log WHERE cs-uri-stem like '%%.asp' GROUP BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ORDER BY TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time),3600)) ASC"

As an added bonus, I’ve created a small cmd (windows) shell script that runs thru all (but the first) of these queries below against a log file. It is located at the following link
download it
Note it requires logparser on the path and has a commandline invocation of:
logparseranalysis.cmd ex061023.log
Logparser and creating separate SQL files (the file: argument)
You may have noticed that these SQLs can get a long, as is the way with SQL. Logparser provides the means to create a text file with these long sqls in it. Additionally the ability to pass arguments is of course a given. Next, an example is in order. To use the commandline below you will need to create a little text file (extension sql) with the contents of the below.
Command Line:
logparser file:iis.sql?logfile=ex061113.log
Text file: iis.sql
-- Start of SQL file --
SELECT
c-ip AS ClientIP,
cs-host AS HostName,
cs-uri-stem AS URIStem,
sc-status AS Status,
cs(User-Agent) AS UserAgent,
count (*) as Requests
INTO output.csv
FROM %logfile%
where time > to_timestamp('18:20:00', 'hh:mm:ss') and time < to_timestamp('18:45:00', 'hh:mm:ss') GROUP BY c-ip, cs-uri-stem, cs-host, cs(User-Agent), sc-status ORDER BY Requests DESC
-- End of SQL file --
Logparser and the files without headers
Don’t have a header in your csv file? With a little work we can define a logparser SQL that will map the empty fields to names with meaning. The automatic header row parsing will need to be turned off.
Command Line:
logparser -i:csv -headerRow:OFF file:dslog.sql?logfile=logwoutheader.log+outputfile=out.csv
Text file: log.sql
-- Start of SQL file --
select To_TimeStamp(MyDate, MyTime) as DateTime, field3 as MachineNane, field4 as PID, field5 as TID, To_Int(field6) as ErrorLevel, field7 as RegExp, field8 as Line, field9 as SID, field12 as Message using TO_TIMESTAMP(field1,'MM/dd/yyyy') as MyDate, TO_TIMESTAMP(field2, 'hh:mm:ss.lx') as MyTime into %OUTPUTFILE% from %LOGFILE% where ErrorLevel >= 35
-- End of SQL file --
Logparser and the eventviewer
Although already covered in a previous article, logparser can also connect to eventviewer and analyze those logs. It can even do this on remote machines. The below SQL is an example on how to detect locked out accounts.
Command Line:
logparser file:lockedoutaccounts.sql?DOMAINCONTROLER=HQDC01C
Text file: lockedoutaccounts.sql
-- Start of SQL file --
SELECT timegenerated AS TimeLockedout,
extract_token(strings, 0, '|') As UserName ,
extract_token(strings, 1, '|') AS OriginatingMachine,
EventID,
SourceName,
Message,
CASE EventID
WHEN 529 THEN 'Invalid userid/password'
WHEN 531 Then 'Account disabled out'
WHEN 539 Then 'Account locked out'
WHEN 530 Then 'Outside of logon time'
WHEN 532 THEN 'Account Expired'
WHEN 535 THEN 'Password Expired'
WHEN 533 THEN 'User not from allowed system'
WHEN 644 THEN 'Account Auto Locked'
WHEN 540 THEN 'Successful logon'
ELSE 'Not specified' END AS EventDesc,
strings
INTO lockedact.csv
FROM \\%DOMAINCONTROLER%\Security
WHERE EventID=644
-- End of SQL file --

Do you want to make it easy have your blog be submitted to the social networking sites like Digg and Del.icio.us?
You can add the submission URLs to the Comment footer of each of your blogger posts.
Below is how to do this in both the new and old version of Blogger.
Heads Up Folks: I've recently updated a simplier way to do this at this new post here.
NEWEST BLOGGER
Thanks to Sabre for looking and finding this. As he writes in his blog SabreNews: HOWTO add "diggit" and "del.icio.us" links to blogger( not beta , but latest version)
1.check whether email post page element is added to your blog .
if not, you can add thru template --->page elements page in your blog admin page
2.after adding email-post , search for in the edit html page of Templage.
do not forget to check "Expand Widget Templates"
3.paste the following snippet before tag
::for DIGGIT
<a expr:href='"http://digg.com/submit?phase=2&url=" +
data:post.url + "&title=" + data:post.title'

This one is a pet peeves of Paul, I admit that sometime Rich Text is really a good thing. In our world of Windows Rich Text, there are times when I want to paste rich text and many more times I want to paste Text-only. My wife actually influenced me into realizing the need is great enough to research it. I've used the Paste Special command for a long time, but have been troubled by the lack of a short-cut key to it.
This article (link below) is a great howto create a macro to a shortcut key for MS Word. Which these days (Office 2003) translates directly to our Outlook 2003 Email Client. If you create this macro in Word, you can use it in composing your Outlook emails.
Paste Special Unformatted Text At Your Fingertips
The next extension would be to create a Windows wide Paste Special shortcut key. Sure, I'll add it to my project list ;)
Update: I won't yet bother with the Windows Wide implementation. It is done:
PureText - http://stevemiller.net/PureText/, a quick trial seems to suggest it works well.
A quote from the web-page:
Have you ever copied some text from a web page or a document and then wanted to paste it as simple text into another application without getting all the formatting from the original source? PureText makes this simple by adding a new Windows hot-key (default is WINDOWS+V) that allows you to paste text to any application without formatting.
After running PureText.exe, you will see a "PT" tray icon appear near the clock on your task bar. You can click on this icon to remove formatting from the text that is currently on the clipboard. You can right-click on the icon to display a menu with more options.
Unless I am switching back and forth between compilers often, I tend to need a kick (or look up) to recall the different implementations of integer types.
The below page of Jack Klein's is just that kick.
Integer Types In C and C++
The introduction, a copy-paste from the above site, and the sample program to run through your compiler is below.
The most common source of confusion are the sizes of the integer types, and the range of values which they can hold. That is because the languages leave many features of the integer types implementation-defined, meaning that it is up to the particular compiler to determine their exact specifications. C and C++ do set minimum requirements for each of the integer types, but the compiler is free to exceed these limits.
Each compiler is required to document its implementation. This information should be available in the printed manuals, online help, or man pages which come with the compiler.
In addition, there is a required standard header named <limits.h> (<climits> in newer C++ compilers) that provides information about the integer types that can be used in your programs at run time. A compiler is not required to provide a header like <limits.h> as a readable text file, but I do not know of any compilers which do not.
There are programs on this page to display the information that this file contains.
While exploring the internet trying to figure out a trivial little problem, I discovered a tool that the w3.org has provided to any and all users on the internet that I forgot about. It can validate a multitude of DOCTYPE from XHTML 1.0 to SVG 1.1 and several flavors in between.
A quote from the validator's FAQ:
"Most pages on the World Wide Web are written in computer languages (such as HTML) that allow Web authors to structure text, add multimedia content, and specify what appearance, or style, the result should have.
As for every language, these have their own grammar, vocabulary and syntax, and every document written with these computer languages are supposed to follow these rules. The (X)HTML languages, for all versions up to XHTML 1.1, are using machine-readable grammars called DTDs, a mechanism inherited from SGML.
However, Just as texts in a natural language can include spelling or grammar errors, documents using Markup languages may (for various reasons) not be following these rules. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation, and the tool used for that is a validator. A document that passes this process with success is called valid.
With these concepts in mind, we can define "markup validation" as the process of checking a Web document against the grammar (generally a DTD) it claims to be using."
This reminds me, I should remember to throw pages I publish through this tool. I expect it to be more pedantic than a web browser, but that is a good thing. I see a few things that I need to fix up on a could of my sites right now.This is a special request HOWTO on Transcoding. There is a soul out on the internet that wants to be able to convert Flash video (FLV) to AVI, MPEG (MPG), or WMV. For those of us out there that don't know this is called Transcoding. This is simply a matter of decoding the video to and an intermediate form and encoding the video to the chosen format.
Windows Instructions: (Linux instruction are down below)
Prerequisites for the method described below.
1. Firefox
2. The Video Downloader plugin for Firefox
3. Riva FLV Encoder 2. A free FLV encoder that can transcode as well.
The step-by-step HOWTO:
1. Pick a Flash Video to download. Click the Download Video Link.
2. Save the FLV video. Make sure to Rename it with an flv extension. It is weird that Video Downloader doesn't let us pick a name.
3. Start Riva FLV Encoder.
- Pick your FLV file or the input.
- Pick the location and name of output file
- Pick the extension you'd like to transcode into. (AVI or MPG). In my example I chose AVI.
- Press the encode button.
And there you have it, tada, you are done. When the Riva FLV Encoder 2 is complete, you've transcoded into another format.
Be aware that you might need to specifically have the codec for the AVI/MPG encoding you just did.
Reading briefly on the forum of Riva it appears that there are occasional gitches, sound problems with transcoding. It isn't a specifically supported operation, either.
Riva Links:
Riva Homepage
Riva Forums
Do you want to do this for Linux?
Take a look at this: Converting flv to mpeg in Linux
Of course you can download a flv file with Firefox in Linux
You will need ffmpeg.
And the simple commandline:ffmpeg -i videotoconvert.flv -ab 56 -ar 22050 -b 500 -s 320x240 output.mpg

Not that this is very technical, but yesterday I found a good site for sharing and getting wallpaper/desktop backgrounds.
InterfaceLIFT's content is entirely vistor-submitted and is intended to be shared. They do a great job of search and provided a multitude of resolutions from 1024x768 to 2560X1600 as well as a number of other formats (ipod/sony psp).
My search for "Seattle" returned several of great photos of the city. Another search for "Vancouver" returned even more.
InterfaceLIFT: High-Resolution Wallpaper
The more sharing, the merrier and who can complain at the price of nothing?
And if you are looking for other art they have icons too. Have a new app that you want a cool icon for? I'd check these ones out.

As a comparison to my last post, all that work of installing applications is moot in Linux.
To create an image (link to a more verbose explanation) use dd on an unmounted CD/DVD drive:
dd if=/dev/cd of=cd.iso
To mount an image, if your kernel is compiled with the loopback block device and ISO 9660 built in (link to a more verbose explanation):
mount -o loop -t iso9660 cd.iso /mnt/isoimage/CDs/DVDs, who needs them?
It is better to just mount the ISO image you need and live in the virtual world; when that works for you. It is harder to do an OS installation like that, but for many other cases, this is fine.
For Windows the best way to do that is to use Daemon Tools CD/DVD emulator.
the Daemon Tools download link
However, you may use the MS tool (not as slick as daemon-tools and unsupported ), it can be downloaded at:
Microsoft's Virtual CD/ISO mounting tool (Virtual CD Control panel)
Don't have an ISO? Create your own: ISO Recorder v2. This allows a simple right click on a CD drive to write an iso. e.g:
Wikipedia on ISO

I never thought to try this, but the multiple rename is built in to Windows. It is simple enough. (1) Select multiple files. (2) Rename one of them. (3) The others will be renamed and have a sequence of numbers appended to the end of the file name. It is a little more verbose at the below link.

After the invent of Google's Webmaster tools there appeared the Yahoo Site Manager. I suspect that MSN is going to be next in that space. It is in these tools that the user gets the ability to configure some of the high level details for search engine optimization.
(1) Google - Webmaster Tools
(2) Yahoo - Site Explorer
(3) MSN/live search - MSN Search Web Crawler and Site Indexing Tools and Services for Site Owners - No tools/submission
(4) Ask.com - Webcrawler information - No tools/submission
For those of you that are casual interested in increasing your page ranks/positions, this would be these would be the places to go.
At this point in time, the primary functionality these appear to provide is the ability to submit Sitemap feeds to the search engine. Allowing for two methods of listing sites for these search engines, (one) the crawler/bot and (two) the submission of URLs.

I've been in a number of organizations where the mystery of who, what, where, when and how an account got locked out is umm, a mystery. This is because the regular login/logout data and other authentication data is bundled in with the 1 or 10 errors per day. The truth is obfuscated by too much data. The biggest problem always appears to be with service accounts, with a number of dependencies on an account.
It turns out it can be relatively simple to right a MS logparser query to hunt out this information. AKA, logparser is your best friend. The second think to note is EventID 644 indicates the event that is written when an account is locked out. The rest is really the details.
This is my little documentation area of regexps that I create when I need to convert one for of text to another. Being in Windows, I've taken to simply using the Visual Studios regexp Find and Replace.
My plan is to update this entry as do other regexps in my day to day work life.
First off feel free to check the Use: Regular Expression button in the Find and Replace Dialog
(1) IDL definition into PL/SQL
To replace:
LINEITEMFLAG_****** = 1, //bit 1
with
insert into lineitem_flags values ('1', 'LINEITEMFLAG_****** Description', 'LINEITEMFLAG_******');
regexp search for: {LINEITEMFLAG_[A-Z,_]*}:b*=:b*{.*},.*$
regexp replace with: insert into lineitem_flags values ('\2', '\1 Description', '\1');
Feature of the day from Google: build your own custom search engine from Google's data.
Check it out at Google Co-op Custom Search Engine.
Google's FAQ is here.
Why would you want this? For instance what if you wanted a search engine for your own 7 sites. You could use this to make a search for these 7 sites.
Inspired by my wife's difficulty connecting to the internet due to new security policies at her organization, I decided to try a proxy to allow her to use Windows Live Messenger.
The Linux SOCKS proxy server implementation these days is made under the name DANTE. Their site is here.
In Gentoo it is in our Portage Tree so the step-by-step is here:
logoutput: syslog
internal: eth1 port = 1080
internal: 127.0.0.1 port = 1080
external: 1.2.3.4
# or
external: eth0
To achieve full access (no username/password).method: username none
# Not using authentication, so unnecessary
#user.privileged: proxy
user.notprivileged: nobody
The access controls for sockd daemon are last. They are checked against in the order they appear in the configuration file. Notice, don't open your proxy server to the wild world - you've been warned.The first three directives control which IP ranges that have accesss to the server.
- The from: is were the details of the IPs are added. In my cause it is the IP space the clients live in.
- The to: option is one of the IPs the proxy server is bound to that the given IP range can speak to. It is set to the addresses Dante/sockd is listening on.
The last of the three drops any requests that don't match either of the first two directives.
client pass {
from: 192.168.0.0/16 port 1-65535 to: 0.0.0.0/0
}
client pass {
from: 127.0.0.0/8 port 1-65535 to: 0.0.0.0/0
}
client block {
from: 0.0.0.0/0 to: 0.0.0.0/0
log: connect error
}
The next four configuration points control who 'routing'.block {
from: 0.0.0.0/0 to: 127.0.0.0/8
log: connect error
}
pass {
from: 192.168.0.0/16 to: 0.0.0.0/0
protocol: tcp udp
}
pass {
from: 127.0.0.0/8 to: 0.0.0.0/0
protocol: tcp udp
}
block {
from: 0.0.0.0/0 to: 0.0.0.0/0
log: connect error
}
sockd -V // this verifies configuration and exits
sockd -d // this enables debugging to the console.
That will start Dante in debugging mode.This is done millions of times a week, I am sure. I just want to write it down so I hope to imprint it on my brain. It is very simple with Gentoo.
rc-update is the tool that Gentoo uses to abstract the guts that often are associated with adding a service to certain runlevels.
Example with adding ntpd to the default run level.
rc-update add ntpd defaultNAME
RC-UPDATE MAN page details.
My wife found that the Washington State Department of Transportation started creating traffic flow maps for mobile devices for the Greater Seattle (Puget Sound) area. One problem though, the page layout isn't ideal for most of our commuting; the maps are split across our routes. Downloading two pages on your blackberry? No thanks.
The solution? Build our own HTML page that references the all the small images so all of the images are loaded with one page. Then create links to the other reference pages such as the travel times.
Do you want to use our Seattle traffic flow maps for mobile or wireless devices? Just use the link you like better:

Seattle (WSDOT) traffic flow for handheld devices
This HOWTO is for Windows XP. Traffic maps are becoming increasingly predominant. The age of the internet has improved us? In Seattle the traffic map is actually rendered as a GIF image.
If you are in the lucky few cities of:
Atlanta, San Francisco Bay Area, Chicago, Denver, Houston, Los Angeles, Louisville, Milwaukee, Minneapolis, OC/Inland Empire, Phoenix, Portland, Salt Lake City, San Diego, San Fernando Valley, Seattle
You can use the TrafficGauge download.
However, I've found the WSDOT traffic map is much more detailed than TrafficGauge.
An alternative solution is:
The setting up of a Sitemap file for a Blogger/Blogspot.com is an easy thing to do. The question of what is a Sitemap file and why should I have one? is answered here
Prerequite:
(1) your site setup/verified in Google Webmaster Tools (more on that here my blog entry on that).
HOWTO:
(1) Login to Webmaster Tools (link)
(2) Click On the Add a Sitemap link
(3) Choose Add General Sitemap
(4) type in: *********.blogspot.com/rss.xml (your blog name for *********)
(5) Click on Add Sitemap button.
You are done! That is it. Simple.
After posting this I found that there is also an equivelant site at Yahoo - Yahoo Site Explorer It functions similarly and you could basically do the same thing over there.
There are two important things you can do with the Google Webmaster tools for your blogger site.
One -> Verify your site
and
Two -> Submit a sitemap.
What we are interested in here is verifying a Blogger site (ONE!). So here is how to do that.
** Google Webmaster Tools Verify your Blogger site. **
(1) Control your blog site through Google Webmaster tools - login/signup for Google's Webmaster tools and add your blogger site *****.blogspot.com
(2) Click on the Verify link
(3) Choose Add a Metatag - note the META tag information
(4) In New Tab (Browser): Login to your Blogger account. Click on your blog of interest and click on the template tab. After the < >> tag paste in the META tag information as found in step (3)
(5) Republish your entire blog.
(6) Go back to the Google Webmaster tools - Click Verify. You are done and your blog has been verified. The next step you'll want to do is add a sitemap.
I just googled this "port forwarding remote desktop putty" and just realized this is easy. I am remote desktop'ing' from windows machines outside of my home network into my home LAN into my Windows XP machine. PuTTY and openSSH can make this easy, maybe even ultra easy!
Prerequistes:
I just bumped into something I've never done before but think is really cool. Tunnelling HTTP/Port 80 traffic through SSH.
A scenario that is valid for me. I would like to view a intranet website that is behind a firewall/router. The website isn't meant for public consumption, but for myself. For instance the D-Link Wireless router DI-724DU configuration page for my home network.
What you need:
(1) Server servicing SSH -- in my case a Gentoo Linux machine running SSHD and configured correctly). Reference name: remotehost.remotedns.org
(2) The DI-724DU (or some other router with port forwarding functionality). Reference name: di724-192-168-0-1 (192.168.0.1 is the default ip)
(3) The SSH port being forwarded to the above named server .
(4) A SSH client -- for me openSSH on an VMWare server with Gentoo on it (outside of my home LAN): Reference name: host.outsidenetwork.com
On the VMWare Gentoo Linux machine that is outside of my home LAN simply type:
(1) ssh -L 2022:192.168.0.1:80 username@remotehost.remotedns.org
where 192.168.0.1 is IP of the router di724-192-168-0-1
(2) Enter the username's password on the remotehost.remotedns.org machine
(3) Start a browser on host.outsidenetwork.com. Enter http://localhost:2022.
You will get the webpage of the D-Link DI-724 wireless router.
Cool! Simple as 1,2,3!
This can be accomplished in a variety of ways. However, I'll tell you the one way that I've used that seemed easy to integrate with the Blogger platform.
I am using sitemeter one of the many tracking sites out there.
I admit the following only: their website interface isn't completely smooth. I know what I wanted and for some reason the sitemeter site didn't lead me to it immediately. Maybe they need a step-by-step for the I-am-too-busy-to-read soul?
To add sitemeter.com tracking to your Blogger Blog:

It has come to my attention that there is significant interest in installing DB2 on Gentoo Linux.
I am running the kernel 2.6.17-gentoo-r8 on an AMD Athlon(tm) XP. It is a fully up to date on all installed packages as off the writing of this Blog.
1. Pre-requistes
Emerge the rpm package and any of its pre-requisites:
emerge rpm
2. Installation
Follow the installation section of 15.2 at: The Linux Documentation Project - Installing DB2 Version 8.2 on Gentoo (2005-01-17)
Pay attention to that step 4. It suprised me. You need to type in the product name of the only product on the list. Intuitive?
3. Post Installation configuration
Follow steps 1 - 3 in section 15.3 at: The Linux Documentation Project - Installing DB2 Version 8.2 on Gentoo (2005-01-17)
Insert a step 3.5: Ensure / directory access read permissions for users in my out of the box installation of gentoo see further detail in this post of mine. As root Run this command:
chmod a+rx /
Continue with step 4
4. I also enabled remote connections section 15.3.1: The Linux Documentation Project - Installing DB2 Version 8.2 on Gentoo (2005-01-17)
5. Install IBM Software Developer's Kit for Java:
rpm --force --nodeps -ivh db2/linux/Java-1.4/IBMJava2-SDK-1.4.1-2.0.i386.rpm
6. I was then able to run db2cc as the user db2inst1.
Following all that I created a database through the control center.
My next goal is going to be a tougher one (I suspect): to see if I can install Rational CQ on Gentoo.
Enjoy,
Paul
'Which network drivers to compile into the kernel? ' This has been a common question of mine theme over many years of using Linux. From Slackware of 1996 days to last month when I rebuilt the kernel on my Gentoo Linux server. I don't compile the kernel often, and in the months between it happening or when I bring up a new machine and I didn't remember which adapter I installed the week before, etc.
In the past this brought me to the following
(1) Non-optimal - Open up the computer case, physically inspect the network card
(2) Non-technical - Label the back of the Ethernet Adapter card with the vender/model
(3) Latest - run the command: lspci | grep Ethernet
lspci - List all PCI devices
Note this could also remind you of what video adapter is installed, or any other PCI adapter for that matter.
I've been using www.ss64.com for several years to remember:
(1) Windows NT, 2000, XP, 2003, etc shell commands
(2) Oracle PL/SQL syntax
(3) Bash Shell commands
Here is a link to the Bash Shell commands: Linux commands
I also noticed while composing this post they have a SQL Server 2005 section. That is news to me. I recommend using this reference for either the Windows or bash shell in a 'what was that command syntax sort of moment'.
Even the simple things can confuse. Imagine seeing this message?
* An update to portage is available. It is _highly_ recommended
* that you update portage now, before any other packages are updated.
* Please do so and then update ALL of your configuration files.
What would a reasonable person do? Cry? Probably. Why doesn't it strike me immediately to use portage to update portage? I don't know.
The solution:
emerge portage
VMWare has been doing a great job in PC virtualization. I've been using VMWare as a test bed for attempting new configurations in Gentoo.
Many have worked on the Gentoo installation since I did my installation around May of 2006. It was a significant amount of work gleening thru the various different VMWare articles in the gentoo Wiki to understand it. Quite possibly I don't yet, but it works day in and day out, so it is a 'close enough'. I am writing this up months after the facts, so I might be a little fuzzy on the details, so don't let me distract you.
Googling on it today Oct. 8, 2006 reveals this, I might try that if I were ready to try again.
HOWTO Install VMWare Server - Gentoo Linux Wiki
The primary article I used in May 2006:
HOWTO Install Gentoo on VMware in Windows NT/2K/XP
Key recollections:
- Download Gentoo ISO
- boot from CD in the VMWare machine
- Recompile Kernel (to get the Network/Disk details all worked out)
- Install X Windows
- Install VMWare tools (this was the most work as I recall -- hopefully is has been cleaned up a little more)
As for a 'Should I run gentoo in VMWare'? I would say for sure! Once you are there it is highly useful. At work (a Windows development environment) if I want to use some UNIX tools, I can start up this tiny little VM (relative to my windows) that has a 6GB disk and 256 MB of RAM and it runs just fine, even starting up X Windows and then Eclipse.
