Lonpos - Yesss Löser/Solver in Javascript
BearbeitenDas Programm errechnet 32.288 eindeutige Lösungen, wenn mit einem leeren Spielfeld gestartet wird. Mit den Optimierungen seit v0.9.4 werden dazu auf einer modernen Maschine unter 10.000 s benötigt, getestet mit Firefox 44.

>Implementation notes:
`---------------------
The board spots are represented by an array of an array
of chars, representing ten rows with columns increasing
from 1 in first row, to 10 in the last.
For each tile an anchor sphere is picked, mov'able to a
board spot (r, c). Connected spheres are coded relative
to (r, c) for each direction (x2 if flipside differs) a
tile may be put on board. movX(s..) set X into board s.
slv() queues its recursive invocation on nesting levels
above 7. Below it does a depth first search. Queue q is
processed using setTimeout() consecutively.

4shared-md5sums.php
BearbeitenUnglücklicherweise findet sich beim Freehoster 4shared.com in der Weboberfläche keine Funktion, die MD5-Werte hochgeladener Dateien anzeigt. Die API liefert diese aber auch Nachfrage. Um ein MD5-Listing der eigenen Dateien des Kontos zu erhalten, müssen die Dateien nicht heruntergeladen werden. Es reicht:
- den Code als 4shared-md5sums.php abzuspeichern
- login und pass an die eigenen Kontodaten anzupassen
- php 4shared-md5sums.php über die Kommandozeile aufzurufen
Die Logindaten werden, wie beim Login auf der Weboberfläche, verschlüsselt an api.4shared.com übertragen.

In der Dateiübersicht der Weboberfläche fehlen Filtermöglichkeiten, so ist leider nicht einmal die Sortierung nach Dateityp möglich. Das macht die Auswahl vieler Dateien eines bestimmten Typs schwierig. In Firefox schafft folgendes Scriptlet Abhilfe, dazu mit Shift+F4 das Javascript-Fenster öffnen. Das Beispiel selektiert alle Dateien mit der Endung jpg. Da die Dateiliste asynchron geladen wird, muss die Sicht vorher ganz nach unten gescrollt werden, andernfalls werden nur Dateien der aktuellen Sicht selektiert.
var objs = document.getElementsByClassName("jpgFileExt");
for (var i = 0 ; i<objs.length; i++) {
objs[i].previousSibling.previousSibling.childNodes[1].checked = true;
objs[i].parentNode.className = objs[i].parentNode.className + " jsChecked";

Hugin Parameter animieren
BearbeitenMit Hugin lassen sich Panoramen als Einzelbilder erstellen. In der schnellen Voransicht lassen sich die Positionsparameter zwar live anpassen, es gibt aber keine Möglichkeit für PTBatcherGUI automatisiert mehrere Einzeljobs zu generieren. Das wäre nützlich, falls ein bestimmter Parameter automatisiert mit einer bestimmten Schrittweite von einer Intervallgrenze zur anderen geführt werden soll. Die entstandenen Einzelbilder können dann als Quelle für einen Videoclip dienen. Der Clip "schwenkt" das sonst statische Panoramabild. U.a. die flächentreuen Lambertprojektionen sind für solche Zwecke interessant.
Soll der Gierwinkel z.B. mit 1° Schrittweite über 360° schwenken, so erzeugt das folgende Skript aus einer zuvor bestehenden einzelnen pto-Datei, Frame000.pto genannt, 359 weitere und übergibt sie mit einem geeigneten Präfix an PTBatcherGUI. Bitte darauf achten, dass als Ausgabeformat in Hugin das verlustfreie PNG genutzt wird. Die verlustbehaftete Kompression findet erst am Ziel der Bearbeitungskette, dem Video-Kodierer, statt.
Der Code wurde bisher nur mit einem einzigen Anwendungsfall getestet, es sind evtl. Fehler enthalten. Er wird für interessierte Hugin-Nutzer veröffentlicht und dient evtl. auch nur zur Anregung bei der Lösungssuche zu einem anderen Problem..

wp-fluss-set.sh
BearbeitenDieser Bash/SQL-Code versucht sein Bestes, um aus Flussläufen, die in OSM gespeichert sind und über die Overpass API abgerufen werden können, eine schematische Darstellung zu erzeugen - siehe Vorlage:Flusssymbole und Vorlage:Fluss-Set-Doku. Am Beispiel der Weißen Elster rechnet das Programm ca. 1min 30s, um die Liste zu produzieren. Der Code ist als Proof-of-Concept anzusehen, und bietet sicher Optimierungspotential.
Erkennung von
Bearbeiten- Brücken, -typen und -längen
- allen mündenden und abzweigenden Gewässern
- Lage der Nebenflüsse (links-/rechtsseitig)
- Seen / Stauseen
- Wehren
Notizen
Bearbeiten- der Hauptstrom des Flusslaufs
- muss als benannte Relation in der OSM-DB vorliegen - evtl. unter Verwendung der Relation-ID in fetchdata() anpassbar
- Rollen werden nicht ausgewertet
- die Sortierung der Wege innerhalb der Relation spielt keine Rolle
- wichtig ist, dass alle Teilwege des Hauptstroms enthalten sind, keine Lücken
- der (erste) Weg von der Quelle und der (letzte) zur Mündung müssen in Fließrichtung gerichtet sein
- Wege des Hauptstroms müssen in mindestens einem ihrer name-Tags (name, name:de, name:en, etc.) den Namen der Relation verwenden
- e.g. berücksichtigt werden alle Wege der Relation[name=Rhein], die in mindestens einem ihrer name-Tags Rhein verwenden
- Nebenarme und -flüsse werden
- erkannt, falls sie mit dem Linienzug/Weg des Flusslaufs einen Knoten gemeinsam haben
- nicht erkannt, falls sie lediglich auf dem Streckenzug der umgebenden riverbank enden
- teilweise nicht erkannt, wenn sie gleichrangig eine Insel umfließen und beide Arme den gleichen Namen tragen - dabei werden alle name-Tags durchsucht
- in diesem Fall wird einer der beiden Arme traversiert, der andere ignoriert
- das Inselsymbol gesetzt - manche waterways in OSM, die als Verzweigung erscheinen sind allerdings nur Fahrrinnen desselben Gewässers
- Problem: tragen beide Arme verschiedene Namen und keiner von beiden den des Hauptstroms, kann keine Sortierung von der Quelle bis zur Mündung gefunden werden - Beispiel Hamburg, Norderelbe, Süderelbe, würde name:short nicht existieren
- mögliche Fallback-Lösung (nicht implementiert):
- Relation von Overpass API mit ausgeben lassen
- testen ob main_stream Rolle auf mehr als einem Element verwendet wird (sonst Relation vermutlich nicht gepflegt)
- Tabelle 'river' mittels der main_stream Mitglieder erzeugen, statt auf 'name%' zu prüfen
- Querlaufende Bauten
- Dämme und andere Querbauten werden nur dann berücksichtigt, wenn ihre Geometrie sich mit dem Weg des Flusslauf einen Knoten teilt
- Brücken werden berücksichtigt - dazu bitte als zweiten Parameter "do_crossings" angeben
- Technisches
- es werden Schreibrechte in /tmp und /dev/shm benötigt (kann angepasst werden, erste vier Variablen)
- läuft evtl. unter Cygwin (ungetestet), wenn Abhängigkeiten entsprechend installiert sind
