  • Need help with Swift mailer with Kohana wrapper

    - by alex
    My current code is this $swift = email::connect(); $swift->setSubject('hello') ->setFrom(array('[email protected]' => 'Alex')) ->setTo(array('[email protected]' => 'Alex')) ->setBody('hello') ->attach(Swift_Attachment::fromPath(DOCROOT . 'assets/attachments/instructions.pdf')); $swift->send(); The email::connect() returns an instance of SwiftMailer. As per these docs, it would seem that it should work. However, I get an error Fatal error: Call to undefined method Swift_Mailer::setSubject() in /home/user/public_html/application/classes/controller/properties.php on line 45 I've seen that email::connect() does exactly what the example code in the docs does. That is include the correct file return an instance of the library What am I doing wrong? Thanks

  • Prevent * to be expanded in the bash script

    - by Alex Farber
    Linux bash script: #!/bin/bash function Print() { echo $1 } var="*" Print $var Execution results: alex@alex-linux:~/tmp$ ./sample-script sample-script "*" is expanded to the list of files, which is actually script itself. How can I prevent this and see actual variable value? In general case, var can be more complicated than "*", for example: "home/alex/mydir/*".

  • Das T5-4 TPC-H Ergebnis naeher betrachtet

    - by Stefan Hinker
    Inzwischen haben vermutlich viele das neue TPC-H Ergebnis der SPARC T5-4 gesehen, das am 7. Juni bei der TPC eingereicht wurde.  Die wesentlichen Punkte dieses Benchmarks wurden wie gewohnt bereits von unserer Benchmark-Truppe auf  "BestPerf" zusammengefasst.  Es gibt aber noch einiges mehr, das eine naehere Betrachtung lohnt. Skalierbarkeit Das TPC raet von einem Vergleich von TPC-H Ergebnissen in unterschiedlichen Groessenklassen ab.  Aber auch innerhalb der 3000GB-Klasse ist es interessant: SPARC T4-4 mit 4 CPUs (32 Cores mit 3.0 GHz) liefert 205,792 QphH. SPARC T5-4 mit 4 CPUs (64 Cores mit 3.6 GHz) liefert 409,721 QphH. Das heisst, es fehlen lediglich 1863 QphH oder 0.45% zu 100% Skalierbarkeit, wenn man davon ausgeht, dass die doppelte Anzahl Kerne das doppelte Ergebnis liefern sollte.  Etwas anspruchsvoller, koennte man natuerlich auch einen Faktor von 2.4 erwarten, wenn man die hoehere Taktrate mit beruecksichtigt.  Das wuerde die Latte auf 493901 QphH legen.  Dann waere die SPARC T5-4 bei 83%.  Damit stellt sich die Frage: Was hat hier nicht skaliert?  Vermutlich der Plattenspeicher!  Auch hier lohnt sich eine naehere Betrachtung: Plattenspeicher Im Bericht auf BestPerf und auch im Full Disclosure Report der TPC stehen einige interessante Details zum Plattenspeicher und der Konfiguration.   In der Konfiguration der SPARC T4-4 wurden 12 2540-M2 Arrays verwendet, die jeweils ca. 1.5 GB/s Durchsatz liefert, insgesamt also eta 18 GB/s.  Dabei waren die Arrays offensichtlich mit jeweils 2 Kabeln pro Array direkt an die 24 8GBit FC-Ports des Servers angeschlossen.  Mit den 2x 8GBit Ports pro Array koennte man so ein theoretisches Maximum von 2GB/s erreichen.  Tatsaechlich wurden 1.5GB/s geliefert, was so ziemlich dem realistischen Maximum entsprechen duerfte. Fuer den Lauf mit der SPARC T5-4 wurden doppelt so viele Platten verwendet.  Dafuer wurden die 2540-M2 Arrays mit je einem zusaetzlichen Plattentray erweitert.  Mit dieser Konfiguration wurde dann (laut BestPerf) ein Maximaldurchsatz von 33 GB/s erreicht - nicht ganz das doppelte des SPARC T4-4 Laufs.  Um tatsaechlich den doppelten Durchsatz (36 GB/s) zu liefern, haette jedes der 12 Arrays 3 GB/s ueber seine 4 8GBit Ports liefern muessen.  Im FDR stehen nur 12 dual-port FC HBAs, was die Verwendung der Brocade FC Switches erklaert: Es wurden alle 4 8GBit ports jedes Arrays an die Switches angeschlossen, die die Datenstroeme dann in die 24 16GBit HBA ports des Servers buendelten.  Das theoretische Maximum jedes Storage-Arrays waere nun 4 GB/s.  Wenn man jedoch den Protokoll- und "Realitaets"-Overhead mit einrechnet, sind die tatsaechlich gelieferten 2.75 GB/s gar nicht schlecht.  Mit diesen Zahlen im Hinterkopf ist die Verdopplung des SPARC T4-4 Ergebnisses eine gute Leistung - und gleichzeitig eine gute Erklaerung, warum nicht bis zum 2.4-fachen skaliert wurde. Nebenbei bemerkt: Weder die SPARC T4-4 noch die SPARC T5-4 hatten in der gemessenen Konfiguration irgendwelche Flash-Devices. Mitbewerb Seit die T4 Systeme auf dem Markt sind, bemuehen sich unsere Mitbewerber redlich darum, ueberall den Eindruck zu hinterlassen, die Leistung des SPARC CPU-Kerns waere weiterhin mangelhaft.  Auch scheinen sie ueberzeugt zu sein, dass (ueber)grosse Caches und hohe Taktraten die einzigen Schluessel zu echter Server Performance seien.  Wenn ich mir nun jedoch die oeffentlichen TPC-H Ergebnisse ansehe, sehe ich dies: TPC-H @3000GB, Non-Clustered Systems System QphH SPARC T5-4 3.6 GHz SPARC T5 4/64 – 2048 GB 409,721.8 SPARC T4-4 3.0 GHz SPARC T4 4/32 – 1024 GB 205,792.0 IBM Power 780 4.1 GHz POWER7 8/32 – 1024 GB 192,001.1 HP ProLiant DL980 G7 2.27 GHz Intel Xeon X7560 8/64 – 512 GB 162,601.7 Kurz zusammengefasst: Mit 32 Kernen (mit 3 GHz und 4MB L3 Cache), liefert die SPARC T4-4 mehr QphH@3000GB ab als IBM mit ihrer 32 Kern Power7 (bei 4.1 GHz und 32MB L3 Cache) und auch mehr als HP mit einem 64 Kern Intel Xeon System (2.27 GHz und 24MB L3 Cache).  Ich frage mich, wo genau SPARC hier mangelhaft ist? Nun koennte man natuerlich argumentieren, dass beide Ergebnisse nicht gerade neu sind.  Nun, in Ermangelung neuerer Ergebnisse kann man ja mal ein wenig spekulieren: IBMs aktueller Performance Report listet die o.g. IBM Power 780 mit einem rPerf Wert von 425.5.  Ein passendes Nachfolgesystem mit Power7+ CPUs waere die Power 780+ mit 64 Kernen, verfuegbar mit 3.72 GHz.  Sie wird mit einem rPerf Wert von  690.1 angegeben, also 1.62x mehr.  Wenn man also annimmt, dass Plattenspeicher nicht der limitierende Faktor ist (IBM hat mit 177 SSDs getestet, sie duerfen das gerne auf 400 erhoehen) und IBMs eigene Leistungsabschaetzung zugrunde legt, darf man ein theoretisches Ergebnis von 311398 QphH@3000GB erwarten.  Das waere dann allerdings immer noch weit von dem Ergebnis der SPARC T5-4 entfernt, und gerade in der von IBM so geschaetzen "per core" Metric noch weniger vorteilhaft. In der x86-Welt sieht es nicht besser aus.  Leider gibt es von Intel keine so praktischen rPerf-Tabellen.  Daher muss ich hier fuer eine Schaetzung auf SPECint_rate2006 zurueckgreifen.  (Ich bin kein grosser Fan von solchen Kreuz- und Querschaetzungen.  Insb. SPECcpu ist nicht besonders geeignet, um Datenbank-Leistung abzuschaetzen, da fast kein IO im Spiel ist.)  Das o.g. HP System wird bei SPEC mit 1580 CINT2006_rate gelistet.  Das bis einschl. 2013-06-14 beste Resultat fuer den neuen Intel Xeon E7-4870 mit 8 CPUs ist 2180 CINT2006_rate.  Das ist immerhin 1.38x besser.  (Wenn man nur die Taktrate beruecksichtigen wuerde, waere man bei 1.32x.)  Hier weiter zu rechnen, ist muessig, aber fuer die ungeduldigen Leser hier eine kleine tabellarische Zusammenfassung: TPC-H @3000GB Performance Spekulationen System QphH* Verbesserung gegenueber der frueheren Generation SPARC T4-4 32 cores SPARC T4 205,792 2x SPARC T5-464 cores SPARC T5 409,721 IBM Power 780 32 cores Power7 192,001 1.62x IBM Power 780+ 64 cores Power7+  311,398* HP ProLiant DL980 G764 cores Intel Xeon X7560 162,601 1.38x HP ProLiant DL980 G780 cores Intel Xeon E7-4870    224,348* * Keine echten Resultate  - spekulative Werte auf der Grundlage von rPerf (Power7+) oder SPECint_rate2006 (HP) Natuerlich sind IBM oder HP herzlich eingeladen, diese Werte zu widerlegen.  Aber stand heute warte ich noch auf aktuelle Benchmark Veroffentlichungen in diesem Datensegment. Was koennen wir also zusammenfassen? Es gibt einige Hinweise, dass der Plattenspeicher der begrenzende Faktor war, der die SPARC T5-4 daran hinderte, auf jenseits von 2x zu skalieren Der Mythos, dass SPARC Kerne keine Leistung bringen, ist genau das - ein Mythos.  Wie sieht es umgekehrt eigentlich mit einem TPC-H Ergebnis fuer die Power7+ aus? Cache ist nicht der magische Performance-Schalter, fuer den ihn manche Leute offenbar halten. Ein System, eine CPU-Architektur und ein Betriebsystem jenseits einer gewissen Grenze zu skalieren ist schwer.  In der x86-Welt scheint es noch ein wenig schwerer zu sein. Was fehlt?  Nun, das Thema Preis/Leistung ueberlasse ich gerne den Verkaeufern ;-) Und zu guter Letzt: Nein, ich habe mich nicht ins Marketing versetzen lassen.  Aber manchmal kann ich mich einfach nicht zurueckhalten...

  • How should a one-man development shop document their code?

    - by CKoenig
    Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

  • Why are there so many man-made edge cases in IT, and is there any hope for simplification / unificat

    - by Hamish Grubijan
    This question is meant to generate discussion and so it is marked as community wiki. My observation is that the field of information technology grows so rapidly and randomly, that for many it takes a lot of time to learn many intricacies of some tools that will be obsolete in just short 3 years. If you look at the questions asked on StackOverflow ... at least half of them stem from the fact that some language / tool / API / protocol was poorly designed, is backwards and has gotchas. There are so many things which distract developers from converting English into machine code; instead they spend their time configuring stuff and gluing together things that do not really fit. How many times do you pick up somebody else's project (or someone picks up yours :) ) and realize that this program does not need half of the dialogs that it has, and that the logic can be simplified a great deal? But, it had to be made and sold here before a better thing is made and sold elsewhere, and hence all this rush. I often wish that things would just slow down. I do not want Microsoft Windows to run on my car's computer, my watch, my table, my toaster oven, and my toilet seat. I'd rather have Windows that DOES NOT HAVE WINDOWS REGISTRY, I'd rather have Windows that allows two different programs to work on the same file at the same time, the way it works on Unix systems. Microsoft is just an example. I am looking forward to the day when I do not have to worry about Windows vs Unix new line break, when System32 actually means that this directory contains 32-bit binaries, and not 64-bit ones, the day when dll hell and manifest hell are no longer an issue, the day when it takes me a lot less than 3 months on a new job to learn the system. I do not mean learning the entire code base of a product (depending on the size of it, it can take a long time). I mean - remembering which build-assisting scripts are written in Perl and which version of it, and which ones are done through .bat files, when do I need to manually make every file in some directory writable before running a script, or else a critical step of a database maintenance home-grown tool will bomb, and it will take 2 days to clean that up. Makes me wonder if humans enslaved computers, or if it is the other way around. The key is that improving those things will not bring extra revenue, and hence those taking the time to fix crap like that are not "business focused". However, these imperfections irritate me immensely, particularly because my memory is limited - I can hold only a small portion of that useless knowledge of a system in my head at any given point in time. I must not be alone. Did you also happen to notice that a programmer can waste a lot of time on things that should have been a lot more straight-forward? Is there hope? Will things get better/simpler in the future, or will there be a lot more IT crap floating around? I suppose I see diversity of tools, protocols, etc. as a bad thing. Thank you for participation.

  • RPC Fails but passing in SQL Man. Studios works

    - by Justin
    I am calling a stored procedure from a web service in an ASP.Net application. And until a few days ago, all was well. However now when i call it I get an error saying The timeout period elapsed prior to the completion of the operation or the server could not be reached. However when i would run SQL SERVER PROFILER, I could see that the call was getting to the database, but was timing out. I then copied the statement being executed found at the bottom of the Profiler and pasted it into Management Studio and executed it and it finishes in about 7 seconds.. This runs just fine on our production server. It seems to be similar to this question: SELECT DISTINCT not working in .NET application, but works in SQL Mgmt Studio but I see no answer.

  • How to install new Intel Ethernet driver

    - by Alex Farber
    Ubuntu 12.04 x64 doesn't recognize newest Intel Ethernet adapter on my desktop (Intel Ethernet Connection i217-V). I downloaded required driver from Intel and compiled it using make. Now I have: alex@alex64-six:~$ find / -name 'e1000e.ko' 2>/dev/null /home/alex/Documents/IntelEthernetDriver/e1000e-3.0.4/src/e1000e.ko /lib/modules/3.2.0-64-generic/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko The first line is new driver compiled from Intel sources. The second line is probably existing driver from Ubuntu distribution, which doesn't recognize new Ethernet adapter. How can I apply the new driver instead of existing one? Any other solution is welcome. For now, I cannot upgrade to latest Ubuntu release, because I use some third-party products.

  • LINQ und ArcObjects

    - by Marko Apfel
    LINQ und ArcObjects Motivation LINQ1 (language integrated query) ist eine Komponente des Microsoft .NET Frameworks seit der Version 3.5. Es erlaubt eine SQL-ähnliche Abfrage zu verschiedenen Datenquellen wie SQL, XML u.v.m. Wie SQL auch, bietet LINQ dazu eine deklarative Notation der Problemlösung - d.h. man muss nicht im Detail beschreiben wie eine Aufgabe, sondern was überhaupt zu lösen ist. Das befreit den Entwickler abfrageseitig von fehleranfälligen Iterator-Konstrukten. Ideal wäre es natürlich auf diese Möglichkeiten auch in der ArcObjects-Programmierung mit Features zugreifen zu können. Denkbar wäre dann folgendes Konstrukt: var largeFeatures = from feature in features where (feature.GetValue("SHAPE_Area").ToDouble() > 3000) select feature; bzw. dessen Äquivalent als Lambda-Expression: var largeFeatures = features.Where(feature => (feature.GetValue("SHAPE_Area").ToDouble() > 3000)); Dazu muss ein entsprechender Provider zu Verfügung stehen, der die entsprechende Iterator-Logik managt. Dies ist leichter als man auf den ersten Blick denkt - man muss nur die gewünschten Entitäten als IEnumerable<IFeature> liefern. (Anm.: nicht wundern - die Methoden GetValue() und ToDouble() habe ich nebenbei als Erweiterungsmethoden deklariert.) Im Hintergrund baut LINQ selbständig eine Zustandsmaschine (state machine)2 auf deren Ausführung verzögert ist (deferred execution)3 - d.h. dass erst beim tatsächlichen Anfordern von Entitäten (foreach, Count(), ToList(), ..) eine Instanziierung und Verarbeitung stattfindet, obwohl die Zuweisung schon an ganz anderer Stelle erfolgte. Insbesondere bei mehrfacher Iteration durch die Entitäten reibt man sich bei den ersten Debuggings verwundert die Augen wenn der Ausführungszeiger wie von Geisterhand wieder in die Iterator-Logik springt. Realisierung Eine ganz knappe Logik zum Konstruieren von IEnumerable<IFeature> lässt sich mittels Durchlaufen eines IFeatureCursor realisieren. Dazu werden die einzelnen Feature mit yield ausgegeben. Der einfachen Verwendung wegen, habe ich die Logik in eine Erweiterungsmethode GetFeatures() für IFeatureClass aufgenommen: public static IEnumerable GetFeatures(this IFeatureClass featureClass, IQueryFilter queryFilter, RecyclingPolicy policy) { IFeatureCursor featureCursor = featureClass.Search(queryFilter, RecyclingPolicy.Recycle == policy); IFeature feature; while (null != (feature = featureCursor.NextFeature())) { yield return feature; } //this is skipped in unit tests with cursor-mock if (Marshal.IsComObject(featureCursor)) { Marshal.ReleaseComObject(featureCursor); } } Damit kann man sich nun ganz einfach die IEnumerable<IFeature> erzeugen lassen: IEnumerable features = _featureClass.GetFeatures(RecyclingPolicy.DoNotRecycle); Etwas aufpassen muss man bei der Verwendung des "Recycling-Cursors". Nach einer verzögerten Ausführung darf im selben Kontext nicht erneut über die Features iteriert werden. In diesem Fall wird nämlich nur noch der Inhalt des letzten (recycelten) Features geliefert und alle Features sind innerhalb der Menge gleich. Kritisch würde daher das Konstrukt largeFeatures.ToList(). ForEach(feature => Debug.WriteLine(feature.OID)); weil ToList() schon einmal durch die Liste iteriert und der Cursor somit einmal durch die Features bewegt wurde. Die Erweiterungsmethode ForEach liefert dann immer dasselbe Feature. In derartigen Situationen darf also kein Cursor mit Recycling verwendet werden. Ein mehrfaches Ausführen von foreach ist hingegen kein Problem weil dafür jedes Mal die Zustandsmaschine neu instanziiert wird und somit der Cursor neu durchlaufen wird – das ist die oben schon erwähnte Magie. Ausblick Nun kann man auch einen Schritt weiter gehen und ganz eigene Implementierungen für die Schnittstelle IEnumerable<IFeature> in Angriff nehmen. Dazu müssen nur die Methode und das Property zum Zugriff auf den Enumerator ausprogrammiert werden. Im Enumerator selbst veranlasst man in der Reset()-Methode das erneute Ausführen der Suche – dazu übergibt man beispielsweise ein entsprechendes Delegate in den Konstruktur: new FeatureEnumerator( _featureClass, featureClass => featureClass.Search(_filter, isRecyclingCursor)); und ruft dieses beim Reset auf: public void Reset() {     _featureCursor = _resetCursor(_t); } Auf diese Art und Weise können Enumeratoren für völlig verschiedene Szenarien implementiert werden, die clientseitig restlos identisch nach obigen Schema verwendet werden. Damit verschmelzen Cursors, SelectionSets u.s.w. zu einer einzigen Materie und die Wiederverwendbarkeit von Code steigt immens. Obendrein lässt sich ein IEnumerable in automatisierten Unit-Tests sehr einfach mocken - ein großer Schritt in Richtung höherer Software-Qualität.4 Fazit Nichtsdestotrotz ist Vorsicht mit diesen Konstrukten in performance-relevante Abfragen geboten. Dadurch dass im Hintergrund eine Zustandsmaschine verwalten wird, entsteht einiges an Overhead dessen Verarbeitung zusätzliche Zeit kostet - ca. 20 bis 100 Prozent. Darüber hinaus ist auch das Arbeiten ohne Recycling schnell ein Performance-Gap. Allerdings ist deklarativer LINQ-Code viel eleganter, fehlerfreier und wartungsfreundlicher als das manuelle Iterieren, Vergleichen und Aufbauen einer Ergebnisliste. Der Code-Umfang verringert sich erfahrungsgemäß im Schnitt um 75 bis 90 Prozent! Dafür warte ich gerne ein paar Millisekunden länger. Wie so oft muss abgewogen werden zwischen Wartbarkeit und Performance - wobei für mich Wartbarkeit zunehmend an Priorität gewinnt. Zumeist ist sowieso nicht der Code sondern der Anwender die Bremse im Prozess.

  • 2 Days of Share &amp; Point

    - by Mark Rackley
    Groovy man… SharePoint Saturday Ozarks is back for 2010, bigger and better than before. Join us for a far out time and learn more about SharePoint in one day than you could in a year from the man… Yes! SharePoint Saturday Ozarks is back! SharePoint Saturday Ozarks is the largest SharePoint conference in Arkansas, Southern Missouri, and the very north east tip of Oklahoma. Last year we had a great turn out with 20 speakers, 5 MVPs, and attendees coming from Arkansas, Texas, Oklahoma, Missouri, Kansas, Nebraska, Indiana, Ohio, Alabama, Michigan, and Washington. Hey Man… what’s SharePoint Saturday anyway? Sounds like a conspiracy man… Not to worry, SharePoint Saturday is not an arm of the government bent on mind control or any attempt what-so-ever to bring you down man. SharePoint Saturday is grass roots effort started by Michael Lotter (http://www.sharepointsaturday.org/pages/about.aspx). It is a FREE one day event where the best SharePoint speakers gather to present their love, hatred, and frustrations of SharePoint to those lucky individuals who attend. Lessons are learned, contacts are made, prizes are won, food is eaten, assorted beverages are consumed until wee hours of the morning. SharePoint Saturday started with just a few sporadic one day events here and there. However, over the past year SharePoint Saturday has exploded and it’s hard to find a weekend where there is NOT a SharePoint Saturday event happing in some corner of the globe. There are even occasions where there are two SharePoint Saturdays on the same day! Many people are pleasantly surprised at the caliber of speakers at these SharePoint Saturday events. For the most part, these speakers are more eloquent, practiced, and practical than those speakers you find at the major multi-day conferences. These guys aren’t even paid to speak.. they do it out of love man… SharePoint Saturday Ozarks 2009 Alumni We had a star studded cast last year with many returning this year! Just check out the fun that they had… John Ferringer – Admin rockstar… I can still sense the awesomeness   SharePoint poster children Mike Watson & Laura Rogers     Lori Gowin spreading the SharePoint Love Eric Shupps is a little bit country and a little bit rock and roll       Cathy Dew, Sean McDonough, and JD Wade relaxing between gigs Actually, you can see real photos from last year’s SharePoint Saturday ozarks here:  picasaweb.google.com/mrackley/SharePointSaturdayOzarks#    What’s new for SharePoint Saturday Ozarks 2010 SharePoint Saturday Ozarks 2010 will totally blow your mind man. We’re getting the band back to together with many returning speakers and few new faces. Joel Oleson will be speaking this year, maybe he’ll grace us with his song stylings. Sadly, once again, Andrew Connell will not be able to attend SharePoint Saturday Ozarks, however he did feel the need to show his support in his own way. Prizes this year currently include books, software, a Zune HD, and much more! Wait Man… You said 2 days? I thought it was a one day event? Correct you are my herbal smelling friend… SharePoint Saturday Ozarks 2010 will spread the love an additional day this year. The first day will be all about the SharePoint love, on day 2 we will be taking a leisurely float down the Buffalo National River for those interested in a truly unique experience (no banjos allowed please).   Here are the details: WHAT 4 – 5 hour float down the Buffalo National River WHEN & WHERE Sunday June 13th. We will be leaving at 10am from the Parking Lot of: Gordon’s Motel & Canoe Rental Old Highway 7 Jasper, AR 72641 (870) 446-5252 Jasper is about 30 minutes south of Harrison, AR on Highway 7 South. You are responsible for bumming a ride to/from Gordon’s Motel, but they will be shuttling us to/from the river and providing canoes and a boxed lunch. WHAT ELSE? The float trip is dependent on the weather of course, we won’t be floating down the river in a thunderstorm, however I planned SPS Ozarks around a time of year ideal for floating. We aren’t talking class 5 rapids here, you don’t need any real skill, but you need to be okay with possibly tipping your canoe over once or twice. You can bring your own assorted beverages with you, but glass containers are not allowed on the river. I suggest a small cooler with extra snacks and drinks. Also bring clothing you can get wet in (these SharePoint people can get ornery). HOW DO I SIGN UP? When you register for SharePoint Saturday Ozarks, you will have the option to also sign up for the float trip. Seats are limited though! If you do not intend to go, please do not take someone else’s place.  The cost for the float trip will be about $35 dollars per person (which you are responsible for unless we find a sponsor). The price includes shuttle to/from river, canoe, life jackets, paddles, and boxed lunch. Far out man… how do I register??? You can register for SharePoint Saturday Ozarks by going to http://spsozarks.eventbrite.com/ We are limited to 200 people for the conference and 50 people for the float trip, so register today before we are sold out. Lodging for SharePoint Saturday Ozarks will once again take place at the Hotel Seville: Annex Suites are available for $103.20 This is So Groovy.. How can I help? I’m glad you asked! We are still looking for a few sponsors and one or two more speakers. If you are interested please let me know!  You can find out more information at http://www.sharepointsaturday.org/ozarks Hey… wait a minute…. what exactly IS SharePoint man??? Come to SharePoint Saturday Ozarks and find out!!  See you guys there!

  • how get validation messages from mangomapper using rails console ?

    - by Alex
    Hi, I am basically teaching myself how to use RoR and MongoDB at the same time. I am following the very good book / tutorial : http://railstutorial.org/ I decided to replace Sqlite3 by MongoDB using the mongomapper gem. Everything works out about alright, but I am having some non-blocking little issues that I truly wish I could get rid of. In chapter 6, when working with validation I got 2 issues: - I don't know how to get the validations messages back like with Sqlite3. The "standard" code is: $ rails console --sandbox >> user = User.new(:name => "", :email => "[email protected]") >> user.save => false >> user.valid? => false >> user.errors.full_messages => ["Name can't be blank"] but if I try to do the same with MongoMapper, it throws an error saying that errors is undefined function. So does it mean that this is simply not implemented in mongomapper / mongo driver ? Or is there some other clever way to do this that I could not figure ? Additional, 2 things here: - I following the exemple in the book to the line, so I was expecting to be able to use the console in sandbox mode, but apparently that does not work either: (...)ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/console/sandbox.rb:1:in `<top (required)>': uninitialized constant ActiveRecord (NameError) from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:226:in `initialize_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:153:in `load_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:26:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:8:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands.rb:23:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' Also, in the book they call "user" but I need to call "User" (note the capital U) why is that ? Is it like mangomapper does not follow the Ruby naming convention or something ? And finally, I am trying to validate the field email with a regex as shown in the tutorial. It does not throws any errors at the code, but whenever I try to insert it just won't ever accept it unless I comment out the :format option... class User include MongoMapper::Document key :name, String, :required => true, :length => { :maximum => 50 } key :email, String, :required => true, # :format => { :with => email_regex }, :uniqueness => { :case_sentitive => false} timestamps! end Any advices you can provide on those topics would help me a lot ! Thanks, Alex

  • Problem with script substitution when running script

    - by tucaz
    Hi! I'm new to Linux so this probably should be an easy fix, but I cannot see it. I have a script downloaded from official sources that is used to install additional tools for fsharp but it gives me a syntax error when running it. I tried to replace ( and ) by { and } but eventually it lead me to another error so I think this is not the problem since the script works for everybody. I read some articles that say that my bash version maybe is not the right one. I'm using Ubuntu 10.10 and here is the error: install-bonus.sh: 28: Syntax error: "(" unexpected (expecting "}") And this is line 27, 28 and 29: { declare -a DIRS=("${!3}") FILE=$2 And the full script: #! /bin/sh -e PREFIX=/usr BIN=$PREFIX/bin MAN=$PREFIX/share/man/man1/ die() { echo "$1" &2 echo "Installation aborted." &2 exit 1 } echo "This script will install additional material for F# including" echo "man pages, fsharpc and fsharpi scripts and Gtk# support for F#" echo "Interactive (root access needed)" echo "" # ------------------------------------------------------------------------------ # Utility function that searches specified directories for a specified file # and if the file is not found, it asks user to provide a directory RESULT="" searchpaths() { declare -a DIRS=("${!3}") FILE=$2 DIR=${DIRS[0]} for TRYDIR in ${DIRS[@]} do if [ -f $TRYDIR/$FILE ] then DIR=$TRYDIR fi done while [ ! -f $DIR/$FILE ] do echo "File '$FILE' was not found in any of ${DIRS[@]}.
