manipulating image files with ImageMagick  by (various authors)
- Manipulating image files with ImageMagick's convert which can combine a series of images into a single multipage ps, pdf, tiff, even pcl.
 
bynari vs. sendmail, sendmail for windows  by (various authors)
- Until I finally removed all MX records for one site, it was getting up to 300,000 spam messages/day. I'd see 60 instances of sendmail running, but the loads never got high. Truly efficient.
 
CUPS on SCO OSR6  by (various authors)
- Nothing happens to what you're successfully doing. SYSV printing remains the default setting in /etc/default/lpd, unless one day you decide to set it to CUPS.
 
using install server for sco installs`  by (various authors)
- You select install, from other, enter the address and password, then select "Hard Disk" and wham bam, a list of all the stuff installed on the other box.
 
vmware emulation, wd drivers  by (various authors)
- The OSR5 "wd" IDE driver has code in it to work around the quirks of _ancient_ "wd" family disk controllers.
 
Linking suggestions   by Anthony Lawrence
- One thing I never worry about is whether I'm sending readers away. If my content is so uninteresting that you don't come back, well, that's the way it is. I can't entrance every human on the planet, and don't need to either - a small subset of appreciative readers will do just fine, thanks.
 
Ad blindness   by Anthony Lawrence
- How much you are affected by ad blindness in your own advertising efforts may be partially affected by your visitors habits: do your visitors typically read multiple pages per visits, or are you like me, where Google and other search engines drive thousands of people to individual pages.
 
Tracking Ad Performance with Channels   by Anthony Lawrence
- To improve earnings from web advertising from Google, Yahoo or Chitika, you need to be able to track where your earnings come from.
 
Competition in advertising   by Anthony Lawrence
- Competition by the web advertising networks is good for advertisers and web sites - but it never happened. Google owns it right now.
 
The Gorilla, the Cowboy, and the Banana (site advertising)   by Anthony Lawrence
- Three ad providers give different results to the bottom line
 
Quality for whom?   by Anthony Lawrence
- We're helpless waifs, needing professionals to spoon feed us distilled knowledge
 
Review Asrep (Third party reporter for Google Adsense )   by Anthony Lawrence
- Google (TM) won't tell you what pages of yours have the best click through rate
 
Content Management Systems   by Anthony Lawrence
- I write these pages in "vi" (a Unix/Linux text editor) at the command line, and create my pages with Perl scripts that I wrote. Why? I'm as lazy as the next person, and certainly could use the convenience of a canned system.
 
Google Analytics   by Anthony Lawrence
- This is a simple bit of code in your page headers, and then Google takes over tracking visitors, giving you everything you could possibly want to know and more.
 
Google's Data Mine   by Anthony Lawrence
- Remember, Google's "Do no evil" motto is just a motto. I can easily imagine that a very high percentage of web sites will be signing up for this even if they do worry a little bit about the massive power Google may gain from it. This could eventually mean vastly improved ad and search targeting, which is good for Google, good for the sites running Google ads and perhaps even good for the people who view the ads, but it's not good for Google's competition. This information could also be used to improve Google search accuracy, which means it could affect page rank and therefore have positive and negative affects on web sites. In other words, we are willingly giving Google data that gives them a new way to assess our worth. Of course that can be good or bad, but the point is that it's an awful lot of power moving toward one company.
 
A search engine list protocol   by Anthony Lawrence
- No matter what you do for search engine optimization, if the search engines never come a-crawling, it can't help you.
 
Quick question - any ideas?   by Anthony Lawrence
- The person who prefaces their tech plea with "quick question" is hardly ever asking that sort of question. OK, maybe sometimes, and I'll forgive the phrase when it fits, but mostly it's "Quick question - my network is down - any ideas?".
 
CSS Frustration   by Anthony Lawrence
- CSS is wonderful, because it allows the true separation of content and presentation. CSS is frustrating because it doesn't.
 
shmax  by anonymous
- >I have an application that runs on Linux, Redhat 9.0. It allocates a lot of shared memory so I moddified shmmax to allow for this. When I run the application from the Linux machine, or using xtart from a PC, it works fine. I need to rlogin into the Linux machine from a Solaris machine. When I do this, the application won't run and says it can't allocate the shared memory. It is as if shmmax isn't getting used when rloggin into the machine.
 
Point & Click OpenOffice.org 2.0   by Anthony Lawrence
- First, this isn't a 600 page desk thumper. The pre-release version Two CD's will be included - one with OpenOffice for Windows and This does cover the 2.0 release.
 
What do you do for a living?   by Anthony Lawrence
- I hate that question. I hate it because I don't really know how to answer it. Seriously. I don't know what it is I do. No, that's not right: I know what I do, but I don't know how to give the top line of the resume version.
 
Incident Response   by Michael Desrosiers
- Incident Response - The first thing that an organization needs to understand is exactly what constitutes a securityincident, what incidents are reportable and what actions you need to take when an incident occurs.

- ftp from win 98 m/c to SCO unixware 2.1.3 server
 
The Ancient Computer Time Machine   by Anthony Lawrence
- The Ancient Computer Time Machine MITS ALtair, SPS, Ancient Unix R5
 
Trackback Pings   by Anthony Lawrence
- Trackback Pings trackback is an automatic cross-linking mechanism for websites, and particularly for blogs. The basic idea is this: I write an article about xyz. You notice that, and it inspires you to write a similar article at your site. You notify me by a POST request to an address I embedded in my page, carrying data also conveniently found in that same page. My server picks up on that, and adds your page to the list of trackbacks at the bottom of the page.
 
Ad jealousy   by Anthony Lawrence
- Ad jealousy: Google won't let you run certain types of ads more than once per page.
 
Beginning Web Development with Perl   by Anthony Lawrence
- Beginning Web Development with Perl- While Perl may not be the 'cool' language for websites anymore, there are some of us who prefer to work with it because we use it for so many other tasks.
 
So now we shouldn't worry about identity theft?   by Anthony Lawrence
- So now we shouldn't worry about identity theft? There's a big difference between a few charges on your credit card and a credit report that has been polluted by someone else's bad credit.
 
What's it worth to you?   by Anthony Lawrence
- What's it worth to you? AOL purchase of Weblogs, Inc. and the real value of a blog
 
Try some Microsoft fudge - yumm!   by Anthony Lawrence
- Because their test methods reflect Windows internals, not Unix kernel design, Microsoft's comparisons aren't accurate.
 
Understanding Technorati Tags   by Anthony Lawrence
- There have been rumors that Technorati will be bought by Google. If you said "That's nice - what the heck is Technorati?", read on.
 
Microsoft File Sharing   by Anthony Lawrence
- Microsoft File Sharing - If you aren't part of a network domain, it defaults to Simple File Sharing, and that is simple: right click on a folder, say you want to share it, give it a share name, and check whether or not other users can write to files.
 
Rounding time   by Anthony Lawrence
- Rounding time to the nearest fifteen minutes isn't all that difficult with Perl. Perhaps there are faster ways?
 
Tracking Site Problems   by Anthony Lawrence
- As some of you know, I have Foo-web.com and some other sites on another web hosting site. Recently I noticed that I'd frequently get locked up for thirty seconds or so while editing files on that site. I wasn't losing my internet connection, and I wouldn't get dropped off: I could keep on typing and when the connection came back, the screen would catch up. These were frequent enough to be quite annoying and worrisome.
 
Just say no to Microsoft  by Anthony Lawrence
- Just say NO to Microsoft - Tony Bove's book is packed with historical information and advice - worth reading even if you aren't planning on giving up Microsoft
 
Time to ban IM?   by Anthony Lawrence
- Personally, I don't like IM to start with, and wouldn't allow it on any network that I had to maintain. But I'm cranky. Most folks seem to like IM.
 
I'm not retiring   by Anthony Lawrence
- I'm not retiring, just moving: my wife's joint problems will be helped by single floor living, for one thing.
 
Happy Turkey Day   by Anthony Lawrence
- Happy Turkey Day, though new worms won't make anyone happy
 
Opera fixes backticks script - Duh!   by Anthony Lawrence
- Maybe security advisories should have a 'Duh' rating in addition to severity? A little shame might make folks check better on their next batch of code.
 
Service Oriented Architecture Compass   by Anthony Lawrence
- There are a lot of different definitions of SOA floating about, but when you strip away all the suit-mumble, it's concepts every Unix person understands intimately: loose coupling, reuse and interoperability. The distinction between SOA and an API is a little fuzzy at the edges, but an example might clear that up: suppose you have something that can be queried to return customer contact information. In a traditional API, that's going to give you back a structured record and if something new is added to that record (like a new "PDA ip address" field), the API probably has to change along with the clients that use it. With a SOA implementation, the data is probably returned in XML, and a client happily ignores fields it doesn't need or understand. This decoupling is what makes SOA more powerful, but note that it doesn't necessarily have anything to do with XML; any web service like chargen, daytime etc. is a primitive example of a service priented application.
 
Apache Derby - Off to the Races   by Anthony Lawrence
- I found it slightly amusing that a book that starts out extolling how simple and easy Apache Derby is then runs on for over 500 pages explaining it. A small smile was also on my face when I read the author's justifications for using Derby over XML files and how Derby would be a "perfect fit" for small business client databases.
 
Do you think Microsoft believes its own hype?   by Anthony Lawrence
- Recently a Microsoft memo was supposedly "leaked". It seems pretty obvious to everyone that it was actually deliberately released, but never mind that. The real question is whether the memo was written with an eye toward the planned release or was a genuine internal document that they then decided to throw out to the press.
 
NBD (Network Block Device)   by Anthony Lawrence
- NBD (Network Block Device) you can create a file system on it, make it part of a mirror or RAID 5 array and so on. But the actual hardware is somewhere out on the network
 
Web site IP filtering   by Anthony Lawrence
- Web site IP filtering - filter traffic by country of origin
 
Maximum size of a directory   by Anthony Lawrence
- Maximum size of a directory - But there are limits to directories, of course. For one thing, a directory is a file like any other file, and therefore is limited in size by whatever restraints the file system puts upon it. It probably has some minimum space for the name part of its entry, and a fixed space for the inode part, so you couldn't possibly have more entries than could fit in the maximum file size.
 
Domain or not?   by Anthony Lawrence
- Computer networks are often just automatically set up without much thought: if it's a business, it's set up as a domain, if it's home, it's not.
 
File date comparison   by Anthony Lawrence
- Sometimes you want to use the date of a file somewhere else. For this example, we'll use the case where a file shouldn't be overwritten if it was created or changed today. If we are not entirely sure of the parameters, we should stop right there: what does "today" mean? Does it mean anytime after midnight of the day before, or does it mean within the past 24 hours? I have seen "today" actually mean the latter more than once, so keep that in mind when people are loosely tossing around "today".
