What is Leon doing?


00-11-6 mo Searched for standards suitable for JS implementation. Wrote ResizeAllText and DeleteLayer.

00-11-2 th Classes for whole day

00-10-26 th cache upgraded. ww2com needs document locking for MDI interface. Mozzila uses .mailboxlist for IMAP.

00-10-25 we As far as I can remember this is my second Palm crash. Unexplained. Thanx God I have a good backup.

00-10-24 tu Accidentaly downgraded cache.

00-10-23 mo Continued with chromosomg properties description. Started FreeBSD source upgrade for both servers as the kernel on the cache is newer than system and we get proc size mismatch. It seems that I need new version of Linkmaster.

00-10-20 fr SMP cluster now working with nfsswap and overclocked to 522MHz.

00-10-19 th Written Autocad database reactor for polylines. Tavčar requgsted Spicer Imagenation C-API example for CGM markup. Lost 4 hours to find out that default units are inches for coords.

00-10-18 we Found that emacs on the stations has html hook for latin-2. Squid redir added for dnevnik.si ads.

00-10-13 fr Installed Junkbuster proxy on cad. A lot of patches was needed for FreeBSD port.

00-10-12 th Went to Interdiskont.

00-10-11 we This and that. SMP cluster finally gets running with NFSswap. First tests show that it works. For best performance some kernel tuning is still needed.

00-10-10 tu Statement for students.

00-10-9 mo Finished JS tutorial.

00-10-5 th - su Ill

00-10-4 we JS functions.

00-10-3 tu RCU changed our IP numbers and everything was screwed up.

00-10-2 mo Writting Javascript tutorial. Chess dissection puzzle. Cassini equality.

00-9-26 tu Wrote some cute Javascript examples.

00-9-25 mo Concrete mathematics: MAT-D 203796

Some therms from math:

  • Corrolary: An immediate consequence of a result already proved. Corollaries usually state more complicated theorems in a language simpler to use and apply.

  • Lemma: A short theorem used in proving a larger theorem.

  • Theorem: A statement which can be demonstrated to be true by accepted mathematical operations and arguments. In general, a theorem is an embodiment of some general principle that makes it part of a larger theory. The process of showing a theorem to be correct is called proof.

  • Proposition: A statement which is to be proved.

  • Axiom: A proposition regarded as self evident without a proof. Word axiom is arhaic synonym for postulate.

    Conjecture: A proposition which is consistent with known data, but has neither been verified nor shown to be false. It is synonymous with hypothesis.

  • Iff: if and only iff (necessarry and sufficient)

00-9-22 fr parity error on disk was causep by bad

00-9-21 th newfs -i 65536 -m 2 -o time -d 0 /dev/rccd1 wns used for /home raid after troubles with newfs can't rewrite disklabel. Editing /etc/distab solved the problem on CCD.

00-9-20 we Thumbpdf needs new ghostscript at least 5.5. Formating new ccd for FreeBSD / home.

00-9-19 tu /boot/kernel.conf flags wdc1 0xb0ffb0ff solved cylinder overlap on FreeBSD.

00-9-18 mo ConTex is a promising language for writing pdf files. It replaces LaTeX. Commands are more TeX like. But it is also nice for presentations.

We are unable to format 40GB disk under FreeBSD. I supose the limit is 20GB. Will try larger block slzes.


00-9-15 fr Doing mainly Javascript tutorial and labs for our students. Found jsActive foy JS drawing. No source and thus abandoned. Similar to our phigs applet.

00-9-14 th Horowitz-Sahni decomposition for subset-sum problems.

00-9-12 tu When doing mkisofs it seems that multisession of the same directory writes only new files. It is not clear weather changed files are written. The test for this should be simple.

Fascinated with Golumb (Salzer) seqences.


00-9-11 mo Studied Segal's Variable Harmonic Fit.

00-9-8 fr Having trouble with VBPP formulation. Cutting stock is an example of VBPP application.

00-9-5 we apa ruled out - emphasizes title. Made tandf.bst from apalike and added \shortcite. Student project presentations took whole AM.

Palm trobles with display must be solved by opening the case.


00-9-4 tu Ran VBPP and draw evolution graph for an article. Still didn't found appropriate bst for T&F. Helped one student with marching cube implementation and then it turned out that I wrote 90% of the javascript code.

00-9-4 mo Explaining X resource managment to Tavčar and changed XTerm*vt100*Translations for 8-bit iso8859-2 character input.

00-9-1 fr First release of the article is given out for review. Still far from perfect, but it's a start.

Corrected my plan2html script with tables and fancy colours. Converter still needs month wrap. Irix6 g++ now works with shared libraries, but not with --static. Anyway X11 libs on SGI are only available as shared.


00-8-31 th Still didn't faced the implementation it the article. This needs substantially more time which I am lacking of. Tried to compile g++ 2.95 on the Irix 6.2 but stdlibc++ header files don't get installed. Maybe new configure with --gxx-include-path will help? Then VTK should be compiled OK.

00-8-30 we Article for PPC is comming to the surface. Still I spent to much time consulting students. Like this Progect for my palm. Now it has notes support.

00-8-28 mo Finished with waterway COM conversion. Safearray is deprecated but still usable. CString cannot be used with ObjectARX. But there are conversion utilities.

00-8-25 fr Moved interface declaration into library declaration and now COM fully works. Change will be needep only from SAFEARRAY to VARIANT. Type conversions are much better supported.

00-8-24 th First success w/ InProcServer. But arquments does not go into properties.

00-8-22 tu COM must be changed in ww.

00-8-18 fr COM is not documented as it was in the release 14. Whole Arx documentation is over 800 pages. Corrected help that now correctly finds acrord32.exe. registry entry for path can contain muctiple entries though.

00-8-17 th Must try some example COM app. ThisDrawing coreponds to acadDoc.Application. Maybe Arx extension will help with combining app.

00-8-16 we Started COM Autocad interface for WaterWay. I must finish the article for PP&C. Added cache digests to squid.

00-8-11 fr Just found that squid didn't store any object for two months due to missconfiguration. Corrected and add some tuning for denial of hitbox, doubleclick and counter hosts.

00-8-10 th Abandoned elipsoid method.

00-8-9 we Elipsoid method with implicitly given bounds are not for practical applications. Maybe I should try global optimisation with local bounds with local optimums obtained with knapsack method.

00-8-8 tu It seems that elipsoid method does not have practical properties although the theory states this method as efficient.

00-8-5 sa Designed tables for attic. Expecting proforma at mo.

00-8-4 fr Started to inplement approx method.

Confusion is with rounding of bins where paper states that there is different # of items in groups, but rounding method does equal division.


00-8-3 th Studied Murgolo's efficient approximation method for variable sized bin packing method based on modified linear programming method - simplex. To meet the complexity and error reqs elipsoid method is used. It looks like a quick method to implement with lpsolve package. And a good reference for my genethic alg. comparision.

00-8-2 we Found excelent site techcocor with overview of the printing process. Some people in our lab still thinks that they can publish color documents with Word(yuk). No hope for TLpro 128kbps.

00-8-1 tu Upgraded MTA128ST firmware to 2.44 and hoping for the best with TLpro and MLPPP. Authentication is missing at abakos PPP. Maybe Elsa also uses &+! for dial number concatenation.

00-7-31 mo Interpilot was causing fatal exceptions after palm full restore.

00-7-21 fr On holydays till august

00-7-20 th I changed my opinion on switches due to NFS can't get a request slot errors. But maybe nhfsstone is showing us troubles on FreeBSD.

Finally I got some results which compare with Falkenauer's HGGA.-Even better-on case of uniform 120 elements it finds all global optimum solutions!


00-7-19 we Reduce2 now somehow incorrectlly introduces assertion failure in replacement for single element. Corrected improve bins to full replaces but 250 items still does not follow book. And theo should be replaced with best hknown in the main loop.


18.7.00 tu Goinq to Italy today.

17.7.00 mo subset sum performs worse than expeced. NFSswap now mounts but does not work correctly.

15.7.00 sa LanSafe 4.14 requires libnss1-compat.

14.7.00 fr Tried mutation on binpack dataset. No results yet. Patched NFS code for swapping. swapon still does not work. Maybe special NFS export will.

13.7.00 th hfsroot= options with mknbi-linux for netboot must include v3 for version 3 nfs and must be reflected with fstab options.

12.7.00 we Watching exams for two hours and studied Production planning & control and International journalo of Production Research. Got an idea for /dev/nvram to controll processor speed settings but found that FSB is not in the CMOS settings. For first two BPP 120 uniform cases is my program founds optimal solution.

11.7.00 tu Disaster at Abakos caused by lightninq. 100MB hub is broken. Also TV set is was striked. SMPs now works full speed with distributed RC5 option and comet falldown.

10.7.00 mo Thanks god I have a good backup. My palm was left and bateries fell out. New kernel on SMPs and system upgrade.


5.7.00 we No testing today. Debian 1.3 to 2.2 upgrade for Nikola. Configured slapd LDAP server. Installed Koeterman software for Miran.

4.7.00 tu Finished repacking bins and knapsack new bin allocation.

3.7.00 mo Repack one works.

1.7.00 sa Lovro is on track again. Also my Octavia.

30.6.00 fr Finally found the bug in the repack_items. Eliminated items were not regitstered. Lovro was intoxinated with neighbour kid drugs and sent imidiatelly to pediatric clinic. Judita Jerman is the chief nurse.

General principle for dominance criterion:

1. find up to three items to replace with one from eliminated. If it is perfect match then search no more.

2. build feasible pairs


29.6.00 th Got doc file for NetUPS but no serial pinout. Anyway, LanSafe works without a problem. Also group broadcast. But ups is a 750VA not 450 :). Hash_set problem is still persistant. Need some more assertions to be done to track the bug.

28.6.00 we exide is now powerware. LanSafe3 4.14 should work with debian 2.2 Max curent f/ 450VA is 2A! Hub should also be on the UPS. matjaz.mrvar@brindis.si promissed pinout specification for UPS.

STL hash_set works different than set on Bins although it should do the same. It seams that past the end is not the same. What if we exaust the available items?
