I must have lost track of what I did during which test - it does indeed make a difference. On the other hand - please bear with me while I think "out loud" about this - since the only place that difference shows up is in the cited "hit context" paragraphs in Hyperestraier and not in the content itself, I'm not sure how much extra effort this deserves. In order to make that small change - i.e., not have the HTML markup appear in the cited paragraph, which only shows up for a second or so during the process - you'd have to split the files into two streams, index each of them individually, then do 'extkeys/optimize/purge' on both... pretty much double the processing time and seriously increase the complexity of the build script. Doesn't seem like much of a payback for a whole lot of work. I suppose you could use "-fx" to keep the modifications really simple: just add something like '-fx htm* H@"lynx -dump -nolist"' to the "estcmd gather" line... but if you're going to do that, you might as well set up processing for all the other "interesting" types of files: PDFs, RTFs, OpenOffice files, etc. (I was going to write about that, too, but figured it would become too complex at that point.) I guess it's a question of deciding where the cutoff point is and building the indexer to reflect that. Overall, I don't think that doing major hackery just to fix the context paragraph is worthwhile. For myself, I'm going to leave it just as it is until I decide to start processing the other filetypes. -- * Ben Okopnik * Editor-in-Chief, Linux Gazette * http://LinuxGazette.NET * +-+--------------------------------------------------------------------+-+ You've asked a question of The Answer Gang, so you've been sent the reply directly as a courtesy.

Yup, this only starts to matter if you're searching lots of different filetypes.

The way I saw it, trying to convert all the PDFs at once would really play hell on my poor underpowered laptop. :) So, I didn't actually go into indexing all the PDFs and such, although I did a couple of small test runs just to see what it would be like. > The approach that worked best (failed least) was to run "file -i" on a > fileset to get the MIME types, and then make a few passes through the > resulting list to index what I could. Here's part of the script. That certainly makes sense. I figured that for a simple indexing run, all you needed was a pipe of the sort I put together - but for anything more complicated, you'd need tempfiles, for exactly the reason you've stated (multiple passes.) I actually played around with that quite a bit ('tmp=`mktemp /tmp/searchXXXXXX`' plus 'trap "/bin/rm -rf $tmp" 0' are my friends!), and found it useful. [snipping script] Thanks, Karl - I was actually going to write something like this for myself later. This will give me a good start on it; possibly, it'll be of help to any of our readers who have been following along with this. -- * Ben Okopnik * Editor-in-Chief, Linux Gazette * http://LinuxGazette.NET * +-+--------------------------------------------------------------------+-+ You've asked a question of The Answer Gang, so you've been sent the reply directly as a courtesy.

My ideal setup (not there yet, but I'm inching closer) is to have two distinct filetrees on a workstation or server. The first tree would be /, /usr, /src -- all the junk we know and love. The second tree (call it /shadow for now) would have drafts for most files under the first tree. (If you didn't see the first Estraier article, drafts -- or ".est" files -- are the guts of the system; they hold the stuff that's actually indexed.) I don't much like databases for search/retrieval because it's not a really great fit. I don't like millions of tiny files, either; if you go down hard and have to run fsck, you not only have time for coffee, you can go to Columbia and pick the beans. My compromise looks like this: * Create 256 directories under /shadow using hex digits 00-ff. Each directory has at most 256 zip files named the same way. * Create a draft for any regular file of interest. One of the attributes in each draft will be the hash of the contents of the file being indexed. The MD5 hash of the filename without newline determines where the draft file will go. For example, we index /etc/motd like so: `` me% echo /etc/motd | tr -d '\012' | md5sum b3097c3f6cd13df91fac6e56735da0b6 - ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ <-- draft-filename ^^^^ <-- directory me% md5sum /etc/motd 58d9f375623df94a2b26b0bcddb20e3d /etc/motd '' The file /shadow/b3/09.zip will hold a draft called 7c3f...b6.est. 7c3f...b6.est holds all the interesting stuff about /etc/motd: keywords, last modification time, and an attribute that holds a signature of the file contents: '' @sig=58d9f375623df94a2b26b0bcddb20e3d '' This way, we can go directly from any "interesting" file on the system to its corresponding draft by looking in no more than one zipfile, and the draft doesn't have to be updated or reindexed for searching unless the original file's contents have changed. I want something that will scale up to tens of millions of indexed files. I did a few experiments with this, and the 1.6 million files on my workstation could fit into 64k zipfiles with an average of 25 drafts per archive. My home directory has ~17,400 files taking up ~300 Mbytes. Unpacking and zipping the equivalent draft files takes up 9.1 Mbytes (about 3% of the original file space) if you don't mind doing without phrase searches. The current fad seems to be "consolidating" people's working files on some massive central server for searching, which is dumb on so many levels; crossing a network to get files that should be local, having a nice juicy single point of failure, etc. If you want to search files without generating enough heat to boil the nearest body of water, put the draft files on the central server and index *those* instead. -- Karl Vogel I don't speak for the USAF or my company The outpatients are out in force tonight, I see. --Tom Lehrer +-+--------------------------------------------------------------------+-+ You've asked a question of The Answer Gang, so you've been sent the reply directly as a courtesy.

Michael Will asked me what had happened since then, so I wrote this: There is no state-of-the-Python-web overview that I know of, but a lot has happened since I wrote that article. Pretty much all new frameworks are written for WSGI, and the older ones have been retrofitted. (CherryPy can run as a WSGI server, Plone can run as an application, parts of Zope have been extracted to independent Repoze components, and Quixote has a WSGI gateway floating around somewhere.) Django works with WSGI sort of, and has been ported to Google App Engine via WSGI. I'm involved with Pylons, a framework that's fully WSGI and modular to the core, built on top of Paste, which is a low-level WSGI library. TurboGears 2 is being built on top of Pylons. This means that different frameworks with different goals and target users can share the same technology, and essentially makes every TG developer a Pylons developer, doubling our developer base. There's a group of WSGI framework developers including Pylons/TG/Repoze.BFG developers that is designing a new framework to potentially supercede all of them, with plug-in personalities to reflect their different application styles. This is still at the idea stage but may have some alpha code by the end of the year. If so it could point the way to the next generation of frameworks. Another big issue is Python 3. Over the next year frameworks will either be ported to Python 3 or replaced by frameworks written for Python 3. (Though the Python 2 frameworks may continue in use for several years.) This has to be done on a dependency basis; e.g., Pylons can't upgrade until all the components it depends on have upgraded. -- Mike Orr +-+--------------------------------------------------------------------+-+ You've asked a question of The Answer Gang, so you've been sent the reply directly as a courtesy.

IF: `` - shell account access is enabled and - the user of that shell account can install programs and - run these programs '' then forwarding is possible. For example, the user can install "slirp" which takes a tty and converts it into a ppp server. The user can then attach a pppd process to the other end of the tty.

However: (1) TAG mailing list members make a point of CCing querents under the assumption that they are not subscribed, specifically so that you _do_ get copies, and (2) you or anyone else are of course very welcome to join the TAG mailing list. (See URL at bottom.) You might merely find following the discussions to be interesting, and eventually might wish to participate.

An "ordinary" user with a shell account can generally download a program to their home directory and run it. So I don't understand your remark.

Yes, I actually talk about the "CC0 Waiver"[1] in my comprehensive rundown (Web page) on legal problems that _may_ result from purporting (as copyright owner) to use any PD grant, including Creative Commons's. The page includes a dialogue I had with CC co-founder, Prof. Lawrence Lessig, where he acknowledges that the concept is problematic, and that the CC0 Waiver is merely CC's effort to "frame the dedication in as complete and reliable way as possible". My page also points out that all such problems can be completely avoided easily by using, instead, a simple one-line permissive licence grant (with example cited) -- or two lines if you disclaim warranties (which is advisable). http://linuxmafia.com/faq/Licensing_and_Law/public-domain.html [1] I guess they must have recently retired that term, and are now calling it "Commons Deed" or CC0. I'll update my page, accordingly. -- Cheers, Bad Unabomber!
