Agreed, but long term the main thing is that you can trust the components you've used not to change interfaces and make you re-visit them once something is working. If you can treat something as a black box and trust it, the size of the component isn't that important. >> You can always do input into temporary tables structured more like the >> input data and process to normalized form later (if needed). > Not if normalising implies any user-interactivity (the usual scenario).

I suppose I hold a grudge longer than necessary. Long ago I inherited a bulletin board system that held user data (login/password/read message list) in a bdb. It had been put in production but the author left before the 'read lists' grew to a point where a bug in bdb made them regularly overwrite random adjacent data, including other people's accounts. It was not a fun experience. Also, you might note that subversion was originally released with bdb as the default backend storage. It isn't now, due to regular problems - although those were probably file locking/sharing issues in multiuser use more than anything else. And the other problem is that if you are just tossing blobs of data in your application's native representation into the DB, it doesn't give you a chance to access it from other languages or platforms when you want to make evolutionary changes or add different components. > I have some processes shared with win boxes over RPC (producung excel > charts) which require that both Perl version and versions of modules > like Storable.pm exactly match, so am largely at the mercy of what the > Activestate repo provides as to what must be run on the linux box too. > I need lots of browsers too (alongside Firefox) for day to day work.

I'd think java would do a better job of charting. Have you looked at the Pentaho tool set? Their site is site is somewhat confusing about what is commercial and what is free, but look for the 'community edition'. Among other things there is a GUI report writing tool to do the layout you want with data from an assortment of sources. Then there is the 'bi-server' that will render the report as a web service with html/pdf/excel/csv/test output - and you can schedule them to be run at pre-set times into a cache or email. Jasper reports and BIRT have similar capabilities. > CentOS is beginning to look more& more like my cup of tea, and since I > gather that a new major is immanent maybe it will support the new Google > Chrome (along with Seamonkey, Opera-11+)?

By 'size' I was actually referring to 'source size' : (1) you say it above "..[all micro] logic..[on] one page ..".(2) the same idea but in a project-macro-logic sense viz a viz sheer quantity of code lines to manage overall. I do rate java for designing GUI-interfaces. No argument there. GUI components ARE objects. But most of the real world aint ..(malfits being the reason for extensibility in OOP).. and it turns out I think that re-usability mostly goes hugely custardly. (And aside, if best programming is the truly 'creative' kind, not just spending time finding the right lego blocks to make new combinations with, then OOP fits badly anyway). > Why BerkeleyDB? I dont know of an embedded-db equivalent that will store 'any and every data exactly as is'. >>> >>> I'd think sqlite first - these days anyway. > > You can always do input into temporary tables structured more like the > input data and process to normalized form later (if needed). Not if normalising implies any user-interactivity (the usual scenario). An early input in the automated background input stream off the wire generates some KEY which a later input of the same stream hours later may try to match against. Would the latest sqlite accept a KEY that was say (& maybe badly) both QP-encoded and HTML-encoded, and even if it did so now would that be guaranteed to endure through future versions of those encodings without ever rejecting? Even if the 'normalising' could be automated satisfactorily to avoid all rejections for sqlite right now within the capture process, it would be biased to sqlite's constraints, an unwanted extra layer that may well also actually corrupt the heavy duty (search-engine)-normalising already being performed on difficult data ..(eg stemming, scoring, indexing). In a sense, BDB serves the "temporary tables" suggestion already, but so much more as to be sufficient in itself. You seem unduly anti-BDB? Quite frankly I have had far less trouble with it than any other db ever. In the past year I have had to do one dump/(re)-load [about 1 hour], and twice delete the environment files [about 1 minute] so that they would self-rebuild on next access. That's it! Which doesn't mean I'm not also always open to suggestions. > > Sqlite should be equally usable - and easier to convert to/from server > backends.

And proves that the time I can make available for discovery falls short by heaps. Nearing closure on a very long project right now, thinking ahead to next steps, reviewing the robustness of past decisions, is very enjoyable and an unusual luxury for me. Playing the 'distro-hopping' game that many seem to indulge in for instance has just been out of the question. I have some processes shared with win boxes over RPC (producung excel charts) which require that both Perl version and versions of modules like Storable.pm exactly match, so am largely at the mercy of what the Activestate repo provides as to what must be run on the linux box too. I need lots of browsers too (alongside Firefox) for day to day work. The old versions of Mozilla, Konqueror and Opera which will run under FC4 are critically dysfunctional on some operations needed. So am looking to try a more up to date team. CentOS is beginning to look more & more like my cup of tea, and since I gather that a new major is immanent maybe it will support the new Google Chrome (along with Seamonkey, Opera-11+)? I wonder if there is a list of packages somewhere. If the repo web-page for CentOS provided the actual repo-address I was going to try direct my FC4-yum there for listings, but cannot seem to find it.

You can also try to set up ACCEPT policy just for testing. - the default gateway for left subnet is 192.168.1.1 (you mentioned router for Internet access). Correct me if I'm wrong. - the default gateway for right subnet I assume is 192.168.236.74. You don't have to do anything with routing here. Every host in right subnet knows where to send replies. - the problem seems to be missing routing information in left subnet. Hosts don't know anything about the right subnet and thus send requests to the default gateway 192.168.1.1. - modifying routing table on every host in left subnet can be solution in case, if there is only a few hosts which need to access right subnet - if you need to have fully accessible subnets, put the static route to default gateway 192.168.1.1 to redirect requests to proper gateway.
