  • How can I implement the Gale-Shapley stable marriage algorithm in Perl?

    - by srk
    Problem : We have equal number of men and women.each men has a preference score toward each woman. So do the woman for each man. each of the men and women have certain interests. Based on the interest we calculate the preference scores. So initially we have an input in a file having x columns. First column is the person(men/woman) id. id are nothing but 0.. n numbers.(first half are men and next half woman) the remaining x-1 columns will have the interests. these are integers too. now using this n by x-1 matrix... we have come up with a n by n/2 matrix. the new matrix has all men and woman as their rows and scores for opposite sex in columns. We have to sort the scores in descending order, also we need to know the id of person related to the scores after sorting. So here i wanted to use hash table. once we get the scores we need to make up pairs.. for which we need to follow some rules. My trouble is with the second matrix of n by n/2 that needs to give information of which man/woman has how much preference on a woman/man. I need these scores sorted so that i know who is the first preferred woman/man, 2nd preferred and so on for a man/woman. I hope to get good suggestions on the data structures i use.. I prefer php or perl. Thank you in advance Hey guys this is not an home work. This a little modified version of stable marriage algorithm. I have working solution. I am only working on optimizing my code. more info: It is very similar to stable marriage problem but here we need to calculate the scores based on the interests they share. So i have implemented it as the way you see in the wiki page http://en.wikipedia.org/wiki/Stable_marriage_problem. my problem is not solving the problem. i solved it and can run it. I am just trying to have a better solution. so i am asking suggestions on the type of data structure to use. Conceptually I tried using an array of hashes. where the array index give the person id and the hash in it gives the id's <= score's in sorted manner. I initially start with an array of hashes. now i sort the hashes on values, but i could not store the sorted hashes back in an array.So just stored the keys after sorting and used these to get the values from my initial unsorted hashes. Can we store the hashes after sorting ? Can you suggest a better structure ?

  • Boost Solr results based on the field that contained the hit

    - by TomFor
    Hi, I was browsing the web looking for a indexing and search framework and stumbled upon Solr. A functionality that we abolutely need is to boost results based on what field contained the hit. A small example: Consider a record like this: <movie> <title>The Dark Knight</title> <alternative_title>Batman Begins 2</alternative_title> <year>2008</year> <director>Christopher Nolan</director> <plot>Batman, Gordon and Harvey Dent are forced to deal with the chaos unleashed by an anarchist mastermind known only as the Joker, as it drives each of them to their limits.</plot> </movie> I want to combine for example the title, alternative_title and plot fields into one search field, which isn't too difficult after looking at the Solr/Lucene documentation and tutorials. However I also want that movies that have a hit in title have a higher score than hits on alternative_title and those in their turn should score higher than hits in the plot field. Is there any way to indicate this kond of scoring in the xml or do we need to develop some custom scoring algorythm? Please also note that the example I've givnen is fictional end the real data will probably contain 100+ fields. Thanks in advance, Tom

  • rpm file conflict after alien conversion

    - by Zitrax
    I have a program for which I generate a .deb file. The .deb file works fine on the systems I have tried it on (also tested with lintian). Previously it has worked to use alien to convert this to .rpm and install it on Suse. However it is now about a year since I tried it the last time and now I get an error when trying to install the alien made rpm on Fedora 11, I get this error: file /usr/share/icons/default.kde from install of testpkg-0.2-2.i386 conflicts with file from package kdelibs3-3.5.10-13.fc11.1.i586 Listing the content of the rpm file: $ rpm -qlp testpkg-0.2-2.i386.rpm / /usr /usr/games /usr/games/testpkg /usr/lib /usr/lib/libfmod-3.75.so /usr/share /usr/share/app-install /usr/share/app-install/icons /usr/share/app-install/icons/testpkg.png /usr/share/applications /usr/share/applications/testpkg.desktop /usr/share/doc /usr/share/doc/testpkg /usr/share/doc/testpkg/changelog.gz /usr/share/doc/testpkg/copyright /usr/share/games /usr/share/games/testpkg /usr/share/games/testpkg/images /usr/share/games/testpkg/images/bb.dat /usr/share/games/testpkg/images/bb_bg.dat /usr/share/games/testpkg/images/bubblemad_8x8.png /usr/share/games/testpkg/images/goldfont.png /usr/share/games/testpkg/lvl /usr/share/games/testpkg/lvl/lvl001.txt /usr/share/games/testpkg/lvl/lvl002.txt /usr/share/games/testpkg/lvl/lvl003.txt /usr/share/games/testpkg/lvl/lvl004.txt /usr/share/games/testpkg/lvl/lvl005.txt /usr/share/games/testpkg/lvl/lvl006.txt /usr/share/games/testpkg/lvl/lvl007.txt /usr/share/games/testpkg/music /usr/share/games/testpkg/music/alfa.it /usr/share/games/testpkg/music/beta.it /usr/share/games/testpkg/sounds /usr/share/games/testpkg/sounds/bounce.wav /usr/share/games/testpkg/sounds/click.wav /usr/share/games/testpkg/sounds/warning.wav /usr/share/icons /usr/share/icons/default.kde /usr/share/icons/default.kde/16x16 /usr/share/icons/default.kde/16x16/apps /usr/share/icons/default.kde/16x16/apps/testpkg.png /usr/share/man /usr/share/man/man6 /usr/share/man/man6/testpkg.6.gz Am I wrong in putting the kde icons in /usr/share/icons/default.kde which seem to be a symbolic link ?

  • Errors in Homebrew on OS X Lion

    - by Bo Tian
    I just ran the Homebrew script as described in the installation page. I then ran brew doctor in Terminal, and it returned several errors. I'm not sure how to fix those errors, please help. brew doctor Error: Some directories in /usr/local/share/man aren't writable. This can happen if you "sudo make install" software that isn't managed by Homebrew. If a brew tries to add locale information to one of these directories, then the install will fail during the link step. You should probably `chown` them: /usr/local/share/man/de /usr/local/share/man/de/man1 Error: You have Xcode 4.2, which is outdated. Please install Xcode 4.3.

  • htaccess mod_rewrite conundrum

    - by kelton52
    Ok, so I have this .htaccess file that contains this <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php?p=%{REQUEST_URI}&%{QUERY_STRING} [L] </IfModule> Problem is, that in apache 2.2.22, the p and the other query objects don't come through, but it works great in apache 2.4.2 . So basically in apache 2.2.22 it just forwards everything to index.php, but it doesn't have any get objects. Any help, thanks. Update Ok so I changed the line RewriteRule . /index.php?p=%{REQUEST_URI}&%{QUERY_STRING} [L] to RewriteRule ^(.*) /index.php?p=$1 [L,QSA] And now on apache 2.2.22 the p GET doesn't go through, but any specific queries I add go through. So If I do http://localhost/index/fun/buns/funds?man=woman on 2.4.2 I get array (size=2) 'p' => string 'index/fun/buns/funds' (length=20) 'man' => string 'woman' (length=5) and on 2.2.22 I get array(1) { ["man"]=> string(5) "woman" } To be clear What's happening on 2.4.2 is what I want, and 2.2.22 isn't cooperating. Another Update Ok so it seems like what is happening is that when I do /index/whatever, it auto assumes index.php, and ignores that, it auto adds the .php to it, when I don't want it to. Any ideas on how to stop that?

  • Why does multiplying a double by -1 not give the negative of the current answer

    - by Ankur
    I am trying to multiply a double value by -1 to get the negative value. It continues to give me a positive value double man = Double.parseDouble(mantissa); double exp; if(sign.equals("plus")){ exp = Double.parseDouble(exponent); } else { exp = Double.parseDouble(exponent); exp = exp*-1; } System.out.println(man+" - "+sign+" - "+exp); The printed result is 13.93 - minus - 2.0 which is correct except that 2.0 should be -2.0

  • Why is used umask ?

    - by fabrizioM
    I am reading some source code and I found at the very begin of the main routine this statement: umask(077); What could be the reason for that? The man page (man 2 umask) states: umask -- set file creation mode mask This clearing allows each user to restrict the default access to his files But is not clear to me why would do that? as a shortcut ?

  • bash: per-command history. How does it work?

    - by romainl
    OK. I have an old G5 running Leopard and a Dell running Ubuntu 10.04 at home and a MacPro also running Leopard at work. I use Terminal.app/bash a lot. On my home G5 it exhibits a nice feature: using ? to navigate history I get the last command starting with the few letters that I've typed. This is what I mean (| represents the caret): $ ssh user@server $ vim /some/file/just/to/populate/history $ ss| So, I've typed the two first letters of "ssh", hitting ? results in this: $ ssh user@server instead of this, which is the behaviour I get everywhere else : $ vim /some/file/just/to/populate/history If I keep on hitting ? or ?, I can navigate through the history of ssh like this: $ ssh otheruser@otherserver $ ssh user@server $ ssh yetanotheruser@yetanotherserver It works the same for any command like cat, vim or whatever. That's really cool. Except that I have no idea how to mimic this behaviour on my other machines. Here is my .profile: export PATH=/Developer/SDKs/flex_sdk_3.4/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/sw/bin:/sw/sbin:/bin:/sbin:/bin:/sbin:/usr/bin:/usr/sbin:$HOME/Applications/bin:/usr/X11R6/bin export MANPATH=/usr/local/share/man:/usr/local/man:opt/local/man:sw/share/man export INFO=/usr/local/share/info export PERL5LIB=/opt/local/lib/perl5 export PYTHONPATH=/opt/local/bin/python2.7 export EDITOR=/opt/local/bin/vim export VISUAL=/opt/local/bin/vim export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home export TERM=xterm-color export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32' export CLICOLOR=1 export LS_COLORS='no=00:fi=00:di=01;34:ln=target:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:*.tar=00;31:*.tgz=00;31:*.arj=00;31:*.taz=00;31:*.lzh=00;31:*.zip=00;31:*.z=00;31:*.Z=00;31:*.gz=00;31:*.bz2=00;31:*.deb=00;31:*.rpm=00;31:*.TAR=00;31:*.TGZ=00;31:*.ARJ=00;31:*.TAZ=00;31:*.LZH=00;31:*.ZIP=00;31:*.Z=00;31:*.Z=00;31:*.GZ=00;31:*.BZ2=00;31:*.DEB=00;31:*.RPM=00;31:*.jpg=00;35:*.png=00;35:*.gif=00;35:*.bmp=00;35:*.ppm=00;35:*.tga=00;35:*.xbm=00;35:*.xpm=00;35:*.tif=00;35:*.png=00;35:*.fli=00;35:*.gl=00;35:*.dl=00;35:*.psd=00;35:*.JPG=00;35:*.PNG=00;35:*.GIF=00;35:*.BMP=00;35:*.PPM=00;35:*.TGA=00;35:*.XBM=00;35:*.XPM=00;35:*.TIF=00;35:*.PNG=00;35:*.FLI=00;35:*.GL=00;35:*.DL=00;35:*.PSD=00;35:*.mpg=00;36:*.avi=00;36:*.mov=00;36:*.flv=00;36:*.divx=00;36:*.qt=00;36:*.mp4=00;36:*.m4v=00;36:*.MPG=00;36:*.AVI=00;36:*.MOV=00;36:*.FLV=00;36:*.DIVX=00;36:*.QT=00;36:*.MP4=00;36:*.M4V=00;36:*.txt=00;32:*.rtf=00;32:*.doc=00;32:*.odf=00;32:*.rtfd=00;32:*.html=00;32:*.css=00;32:*.js=00;32:*.php=00;32:*.xhtml=00;32:*.TXT=00;32:*.RTF=00;32:*.DOC=00;32:*.ODF=00;32:*.RTFD=00;32:*.HTML=00;32:*.CSS=00;32:*.JS=00;32:*.PHP=00;32:*.XHTML=00;32:' export LC_ALL=C export LANG=C stty cs8 -istrip -parenb bind 'set convert-meta off' bind 'set meta-flag on' bind 'set output-meta on' alias ip='curl http://www.whatismyip.org | pbcopy' alias ls='ls -FhLlGp' alias la='ls -AFhLlGp' alias couleurs='$HOME/Applications/bin/colors2.sh' alias td='$HOME/Applications/bin/todo.sh' alias scale='$HOME/Applications/bin/scale.sh' alias stree='$HOME/Applications/bin/tree' alias envoi='$HOME/Applications/bin/envoi.sh' alias unfoo='$HOME/Applications/bin/unfoo' alias up='cd ..' alias size='du -sh' alias lsvn='svn list -vR' alias jsc='/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc' alias asl='sudo rm -f /private/var/log/asl/*.asl' alias trace='tail -f $HOME/Library/Preferences/Macromedia/Flash\ Player/Logs/flashlog.txt' alias redis='redis-server /opt/local/etc/redis.conf' source /Users/johncoltrane/Applications/bin/git-completion.sh export GIT_PS1_SHOWUNTRACKEDFILES=1 export GIT_PS1_SHOWUPSTREAM="verbose git" export GIT_PS1_SHOWDIRTYSTATE=1 export PS1='\n\[\033[32m\]\w\[\033[0m\] $(__git_ps1 "[%s]")\n\[\033[1;31m\]\[\033[31m\]\u\[\033[0m\] $ \[\033[0m\]' mkcd () { mkdir -p "$*" cd "$*" } function cdl { cd $1 la } n() { $EDITOR ~/Dropbox/nv/"$*".txt } nls () { ls -c ~/Dropbox/nv/ | grep "$*" } copy(){ curl -s -F 'sprunge=<-' http://sprunge.us | pbcopy } if [ -f /opt/local/etc/profile.d/cdargs-bash.sh ]; then source /opt/local/etc/profile.d/cdargs-bash.sh fi if [ -f /opt/local/etc/bash_completion ]; then . /opt/local/etc/bash_completion fi Any idea?

  • Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

    - by Richard Lefebvre
    It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011

  • Live vom Oracle Partner Day 2012 in Frankfurt

    - by A&C Redaktion
    Frankfurt a. M. gegen 11:30 UhrCharmante Idee, mit einem Welcome-Lunch in den Oracle Partner Day 2012 zu starten. So kann man bei einem Snack auch gleich die beeindruckende Atmosphäre der Commerzbank Arena auf sich wirken lassen und ist, ehe man sich versieht, mit dem nebenstehenden Geschäftsführer, einer Managerin und zwei Vertriebsmitarbeitern in ein Gespräch über die jeweils letzten Stadionbesuche verwickelt. Überall fröhliches Wiedersehen, viele haben sich das letzte Mal vor genau einem Jahr getroffen, im Radisson Blu, beim OPN Day Satellite. So, die Masse setzt sich in Bewegung – auf geht’s zur Eröffnung: Silvia Kaske fängt an! 13:45 Uhr Die Keynotes waren mal wieder ein thematischer Rundumschlag – und ein kleines Who-is-Who im Oracle Universum zugleich: Silvia Kaske, Senior Director Channel A&C eröffnete den Partner Day, danach stellte David Callaghan (Senior Vice President UK, Ireland, Israel) die EMEA-Strategien für das FY13 vor und Jürgen Kunz (SVP Technology Northern Europe & Country Leader Germany) sprach über die Geschäftsmöglichkeiten mit Partnern. Christian Werner gab in seiner neuen Funktion als Senior Director Alliances & Channels Germany einen Überblick über die neue Struktur des Oracle Channels und stellte das deutsche Team vor. Zum Abschluss folgte mit Prof. Hermann Maurer ein Gastredner von der Academia Europaea, einer prominent besetzten akademischen Gesellschaft, die sich dem besseren Verständnis der Wissenschaft in der Öffentlichkeit verschrieben hat. Er wagte einen Blick in die Zukunft der IT: „Das Beste kommt erst noch“. Wie immer, in einem so komprimierten Programm, bleibt noch die eine oder andere Frage – aber jetzt ist ja Zeit, bei Coffee & Networking noch mal nachzufragen. Kurz nach 14 Uhr Viele haben inzwischen auch das erste Obergeschoss erkundet. In der Partner Service Zone ist das Angebot breit gefächert: Von Oracle Financing über das License Management bis hin zu OPN Specialized dreht sich hier alles um konkrete Angebote für Partner. Nach einem kurzen Abstecher in die ISV-Lounge, geht es weiter zur Expert Zone: Oracle Database, Oracle Options, Fusion Middleware, Applications und Oracle Hardware heißen hier die Themen und an den Infoständen wird bereits lautstark gefachsimpelt. Zurück im Erdgeschoss sieht man noch diverse Partner, Oracle Executives und andere Teilnehmer durcheinander wuseln, um ihre Breakout Session zu finden. Andere blättern im druckfrischen A&C Kursbuch. In den nächsten zwei Stunden stehen Business Opportunities im Fokus – aufgeteilt nach Hardware, Technology oder Sales Partnern – dazu noch die Angebote der VADs, die A&C Partner Sessions und das 1:1 Speed Dating. Einige Partner nutzen parallel die angebotenen Implementation Tests, um direkt vor Ort die Zertifizierung zu erhalten. Das doppelte Angebot der Breakouts ermöglicht den Teilnehmern, an möglichst vielen Sessions nacheinander teilzunehmen. Kein Thema soll zu kurz kommen! Ein AusblickWas erwartet uns noch, im Laufe des Nachmittags? Sehr informativ wird sicherlich das Leader Panel, in dem die teilnehmenden Partner Fragen an Oracle Executives stellen können. Wenn dann die ersten Teilnehmer unruhig werden, hat das nichts mit den Themen zu tun. Nein, es steht vielmehr noch ein spannender Höhepunkt bevor: die Partner Award Ceremony (über die wir später ausführlich berichten werden). Nach einer hoffentlich gelungenen Veranstaltung stellt sich zum Schluss nur noch die Frage, was sich genau hinter der „Red Stack Arena Sports Challenge“ verbirgt. Brauchen wir Turnschuhe?

  • How to thoroughly purge and reinstall postgresql on ubuntu?

    - by John Mee
    Somehow I've managed to completely bugger the install of postgresql on Ubuntu karmic. I want to start over from scratch, but when I "purge" the package with apt-get it still leaves traces behind such that the reinstall configuration doesn't run properly. After I've done: apt-get purge postgresql apt-get install postgresql It said Setting up postgresql-8.4 (8.4.3-0ubuntu9.10.1) ... Configuring already existing cluster (configuration: /etc/postgresql/8.4/main, data: /var/lib/postgresql/8.4/main, owner: 108:112) Error: move_conffile: required configuration file /var/lib/postgresql/8.4/main/postgresql.conf does not exist Error: could not create default cluster. Please create it manually with pg_createcluster 8.4 main --start or a similar command (see 'man pg_createcluster'). update-alternatives: using /usr/share/postgresql/8.4/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode. Setting up postgresql (8.4.3-0ubuntu9.10.1) ... I have a "/etc/postgresql" with nothing in it and "/etc/postgresql-common/" has a 'pg_upgradecluser.d' directory and root.crt and user_clusters files. The /etc/passwd has a postgres user; the purge script doesn't appear to touch it. There's been a bunch of symptoms which I work through only to expose the next. Right this second, when I run that command "pg_createcluster..." it complains that '/var/lib/postgresql/8.4/main/postgresql.conf does not exist', so I'll go find one of those but I'm sure that won't be the end of it. Is there not some easy one-liner (or two) which will burn it completely and let me start over?

  • JSP: Refresh ComboBox options

    Hi, There's a class 'Car' with brand and model as properties. I have a list of items of this class List<Car> myCars. I need to represent in a JSP website 2 ComboBox, one for brand and another for model, that when you select the brand, in the model list only appear the ones from that brand. I don't know how to do this in a dynamic way. Any suggestion where to start? Thanks Update Ok, what I do now is send in the request a list with all the brand names, and a list of the items. The JSP code is like: <select name="manufacturer" id="id_manufacturer" onchange="return getManufacturer();"> <option value=""></option> <c:forEach items="${manufacturers}" var="man"> <option value="${man}" >${man}</option> </c:forEach> </select> <select name="model" id="id_model"> <c:forEach items="${mycars}" var="car"> <c:if test="${car.manufacturer eq man_selected}"> <option value="${car.id}">${car.model}</option> </c:if> </c:forEach> </select> <script> function getManufacturer() { man_selected = document.getElementById('id_manufacturer').value; } </script> How do I do to refresh the 'model' select options according to the selected 'man_selected' ?

  • `# probe: true` in /etc/rc.d/init.d/* files on a RedHat system

    - by Chen Levy

I find no mention of the # probe: true notation in chkconfig man page, nor in any related man pages. Googleing for it also didn't help. Is there a real significance for that line, or is it pure documentation?
