SCCM 2012 - Windows 8 WSUS

- by Owen

We're using SCCM 2012 to deploy Windows Updates on our domain, and our Windows 8 clients have started failing with error 80240438 when they try to update. Windows 7 clients update fine, but Windows 8 clients refuse to do anything. I've done a search online and it seems to only reference Windows InTune. Has anyone seen any similar behavior on Windows 8 machines? If we don't get that error, we're getting 80244021 which seems to indicate that the server can't be found.... but they can resolve it just fine and our exceptions are defined on the proxy too.

Read Linux-formatted (ext3) EBS volume mounted on Windows Server 2008 instance

- by Greg Owen

I've got a Windows Server 2008 R2 instance set up in Amazon EC2. I've also got some Ubuntu instances on the same EC2 account. I'd like to be able to mount the EBS volume from one of the Ubuntu instances onto the Windows instance as an external drive and then access that drive from the Windows instance. I've looked at tools like ext2fsd and ext2 IFS, but these haven't worked (I couldn't get the former to work, and the latter says that it supports Windows 2008 but gives an error when I try to install it, saying that it only supports up to Windows 2003). I know that there are all kinds of tools to view Linux partitions and that there are filesystems that are compatible with both Linux and Windows, but neither of those options works here (I want to be able to attach and detach the Ubuntu volumes on command, rather than have a permanent partition, and Ubuntu EBS volumes are ext3 by default). Anybody know a good tool I should use?

Accessing DHCP Client's vendor-encapsulated-options

- by Jason Owen

In the dhcpd.conf file for isc-dhcpd-V3.1.1, I have set up a vendor options space and defined several different options. I am able to use those definitions to send options from the server to the client in the vendor-encapsulated-options option (code 43). However, the client is also sending vendor options back to the server, in the same way, and I'd like to respond differently depending on the type and contents of the options. As far as I can tell, the the server isn't parsing the client's vendor-encapsulated-options at all - the option operator is just returning null. Is there a way to get the server to populate the options in the vendor space I've defined?

Mysql server won't start - no logs

SharePoint Search: processing filenames containing underscores

- by Todd Owen

We use SharePoint Server 2007 to allow employees to search network file shares, but it seems that underscores in filenames are not treated as word separators when indexing the files. As a result, a search for chocolate will: match "chocolate milkshake.doc" but not match "chocolate_cake.doc" (Of course, this is a simplified example; in practice the content of the second file might include the word "chocolate" and match on that instead of the filename. But the problem itself is real enough, because a common scenario in a corporate environment is that a user knows the the partial name of the file they are looking for and expects to see matching filenames at the top of the search results. And using underscores in filenames is a widely used convention within our company). Underscores are not treated as word separators in the file content either, although this is less of a concern for us. The root cause of this problem is possibly related to the behaviour of the word breakers that SharePoint uses (i.e. the language-specific DLLs that implement the IWorkBreaker interface), although I haven't confirmed this yet. Does anyone know of a workaround for this issue? I have tested with Search Server 2008 Express too (which is based on the same technology), and it is also affected. I do not know whether the problem is fixed in SharePoint 2010 or not.

User given a login prompt when closing Word documents after viewing them in IE7

- by Martin Owen

When using IE7 to view Word documents on our CRM system (an ASP.NET 2.0 application running on Windows Server 2003 and IIS 6 and using Windows authenticaton) I'm finding that a prompt appears when the user closes the document. The Word document is originally opened by clicking a link in the CRM system. Are there permissions that I can set on the folder containing the Word documents to prevent this prompt? I've already tried only allowing the Read permission for the Users group (I've left Administrators with Full Control.) If there's another solution to this without using permissions please let me know. UPDATE: I ran Fiddler as suggested by JD and here is the output from the two responses after the request for the document. The first seems to be a DAV response and the second is the authentication request. How do I prevent the DAV response and just return the .doc on the server? OPTIONS / HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 200 OK Date: Thu, 18 Feb 2010 13:37:36 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MS-Author-Via: DAV Content-Length: 0 Accept-Ranges: none DASL: <DAV:sql> DAV: 1, 2 Public: OPTIONS, TRACE, GET, HEAD, DELETE, PUT, POST, COPY, MOVE, MKCOL, PROPFIND, PROPPATCH, LOCK, UNLOCK, SEARCH Allow: OPTIONS, TRACE, GET, HEAD, COPY, PROPFIND, SEARCH, LOCK, UNLOCK Cache-Control: private ------------------------------------------------------------------ OPTIONS /docs/ZONE%20100-105.doc HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 401 Unauthorized Content-Length: 83 Content-Type: text/html Server: Microsoft-IIS/6.0 WWW-Authenticate: Basic realm="<REMOVED>" X-Powered-By: ASP.NET Date: Thu, 18 Feb 2010 13:37:36 GMT ------------------------------------------------------------------ UPDATE 2: I found a potential workaround for the problem via this post: http://forums.iis.net/p/1149091/1868317.aspx. I moved all of the documents that are being requested into a folder outside of the web root, and created a virtual directory for it (also outside of the web root). When I followed a link to one of the documents in IE and then closed the document I wasn't presented with a login prompt. I should point out that I'm not using FPSE, unlike the person in the forum post. Ideally I don't want to have to put the documents in a separate virtual directory, but this is the simplest solution I've found so far.

Slow Web Performance on two Windows 2008 R2 Terminal Servers

- by Frank Owen

We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load. Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January. We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

What happens when the server that the Remote Desktop Connection Broker goes down?

- by Frank Owen

I would like to setup the Remote Desktop Connection Broker to allow better load balancing of the two terminal servers we have as well as allowing the user to re-establish to the correct server if they get disconnected. My worry is, if I set this up and the server this service is running goes down, does the terminal server stop accepting connections or will they just lose the benefit of having RDCB turned on? I don't want to add another point of failure in this equation unless I have to.

LAMP Server without single failure point + Global Server Load Balancing?

- by José Nobile

I want implement a LAMP Server (Linux Apache MySQL PHP) without a single failure point and with Global Server Load Balancing. I have a server in Cali, Colombia, and other server will be installed in Melbourne, Australia, user in America can use the Cali Server and in Europe, Asia, Africa or Oceania use the Melbourne Server. If any server fail (or load is excessively high), a server must answer all request. Data in MYSQL must be in sync, php files, any configuration in both server must be in sync. I read about of Google DNS Server 8.8.8.8 and 8.8.4.4 and ANY Cast, also about MySQL semisynchronous replication and MySQL Cluster, but what about other things, as crontabs, and the configurations in server? The solution can't depend of APNIC or BGP, only open source software running in Linux.

Why does the Windows XP Task Manager icon disappear from the tray?

- by Jason Owen

One of the more annoying bugs in Windows XP is the tendency for the Task Manager icon to not show up in the tray (aka the notification area). Sometimes it does, sometimes it doesn't, and it's not consistent enough to have an obvious cause. Looking on Google turns up a bunch of forums that have the same problem but no working solution. Why does the task manager icon sometimes not show up? How can I repair it when this happens (how can make it show up when it's missing)? How can I prevent it from not working in the first place, so that I don't have to worry about repairing it after the fact?

Help with user login on Centos 5.6

- by Owen

I added a user for the sole purpose of using SU for root. I did not allow the creation of a home directory when creating the user. So now when I login as this user I get the following: Could not chdir to home directory /home/MYUSERNAME: No such file or directory Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Is this an error, and if so how do I fix it so it is not looking to "resolve" the homedir?

What is meant by Scope of a variable?

- by Appy

I think of the scope of a variable as - "The scope of a particular variable is the range within a program's source code in which that variable is recognized by the compiler". That statement is from "Scope and Lifetime of Variables in C++", which I read many months ago. Recently I came across this in LeMoyne-Owen College courses: What exactly is the difference between the scope of variables in C# and (C99, C++, Java) when However a variable still must be declared before it can be used

Ich bin jetzt Oracle Certified Associate!

- by britta.wolf

Jan Peuker, Absolvent der Hochschule Augsburg und University of Melbourne, hat vor kurzem das Zertifikat Oracle Database 10g Administrator Certified Associate erworben. Er hat uns netterweise mit diesem kleinen Text versorgt: "Die Oracle Zertifizierung beginnt üblicherweise mit dem Oracle Certified Associate. Für diese Zertifizierung ist noch keine tiefgehende Praxiserfahrung notwendig. Um den Titel des Oracle Database 11g Administrator Certified Associate zu erlangen, muss man eine Prüfung zu SQL (z.B. 1Z0-051) sowie eine Prüfung zur Administration (1Z0-045) ablegen. Beide Prüfungen dauern 2 Stunden und haben ca. 80 Fragen von denen etwa drei Viertel richtig beantwortet werden müssen, um zu bestehen. Eine Note gibt es nicht. Die Prüfungen finden immer elektronisch statt, die Software erlaubt das Überspringen und Markieren von Fragen. Während meiner Arbeitszeit nach meinem ersten Studium hatte ich häufig mit dem Oracle Datenbanksystem zu tun. Als ich mein Aufbaustudium an der University of Melbourne absolvierte, wurde mir von der Studienberaterin vorgeschlagen, den Kurs „Advanced Database Administration" zu belegen. Dieser beruht vollständig auf den offiziellen Oracle Trainings-Unterlagen zur Prüfung in Oracle Administration und erlaubt daher die Teilnahme an der offiziellen Zertifizierung. Im Gegensatz zur SQL Prüfung, deren Inhalt man sich gut selbst aneignen kann, hilft bei der Administrator-Zertifizierung ein echter Kurs mit Seminar ungemein. Viele Konzepte lassen sich schwer aus einem Buch lernen. Die Bestandteile der SGA oder das Anlegen von Benutzern mögen leicht zugänglich sein, Redo- und Undo-Management sowie Backup und Recovery kann man nur verstehen, wenn man Beispiele hat und diese an einem Testsystem (keine "kleine" XE-Datenbank, sondern eine "richtige" Datenbank mit Enterprise Manager) ausprobieren kann. Übermäßig viel Zeit habe ich keinesfalls investiert, weil das Grundsystem sehr logisch ist. Für die weniger nachvollziehbaren Bereiche, besonders die neuen Features, habe ich mir Fachbegriffe auf Lernkarten geschrieben und die Trainingsunterlagen am System durchgespielt. Die Prüfung war für mich überraschend schwer, weil das einfache "Tagesgeschäft" deutlich unterrepräsentiert ist. In den Multiple-Choice-Fragen werden viele Besonderheiten und Use-Cases abgefragt (online findet man viele Beispielfragen). Da beide Tests in Englisch sind, sollte man nicht nur in der Terminologie des Oracle Datenbanksystems sondern auch in Fachbegriffen der Datenbankwelt allgemein bewandert sein. Oft machen einzelne Wörter (z.B. redundant oder synchronized, redo log oder redo log buffer) die richtige Antwort aus, ein signifikanter Anteil der Fragen beruht auf Zeichnungen oder Diagrammen, die beschrieben werden müssen. So muss man z.B. anhand eines Log-Auszugs beurteilen, warum die Datenbank nicht sauber geschlossen wurde. Allgemeines Wissen über Datenbanksysteme hilft leider nicht viel, da überproportional viele Fragen zu Oracle-spezifischen Themen gestellt werden, wie z.B. Optimierungs-Dienste (ADDM), Flashback, SQL Loader und ein wenig PL/SQL. Die SQL Prüfung ist dagegen sehr geradlinig - was aber nicht einfacher heißt. Hier kommt es mehr auf Auswendiglernen von Syntax an, was mir persönlich nicht liegt. Vor allem als Anwendungsprogrammierer kennt man oft proprietäre SQL-Funktionen nicht, es fällt schwer, sich einzelne Datumsberechnungsfunktionen, Typkonvertierungen, Namespaces oder krude Join-Methoden zu merken. Auf all dies wird in der Prüfung aber sehr viel Wert gelegt. Auch hier wird man wieder mit zweideutigen Multiple-Choice Fragen konfrontiert, bei denen sich z.B. nur die Reihenfolge der Parameter unterscheidet. Zudem sind die Parameter auch nicht ausgeschrieben, sondern in einem Entity-Relationship-Diagramm gegeben, wobei man auf die richtigen Datentypen achten muss. Mir persönlich war die Zeit fast zu knapp bemessen, weil man bei vielen Fragen erst ein Diagramm, einen Datenauszug oder einen längeren Text lesen muss, um dann die richtigen Statements zu finden. Hier helfen Lernkarten also nur bedingt - stattdessen üben, üben, üben. Durch den relativ niedrigen Pass-Score von 70% kann man es sich leisten, unsichere Fragen zuerst zu überspringen und erst nachdem alle sicheren beantwortet sind, zu überdenken. Die Prüfung ist auf jeden Fall fair. Ich habe durch das Oracle-Zertifizierungsprogramm viel gelernt. Die Datenbanken unter meiner Aufsicht laufen deutlich performanter und liefern höhere Verfügbarkeit, weil ich Probleme eliminieren konnte, die mir vorher nicht klar waren. Eine klassische Misskonfiguration, volle Archive Logs, weil diese mit zu lange gehaltenem Flashback-Speicher kollidieren, konnte ich bereits in einer der ersten Stunden meines Kurses an der Uni Melbourne mit Hilfe meines Professors klären. Beide Prüfungen waren problemlos parallel zu anderen Prüfungen zu absolvieren. Empfehlen kann ich eine gründliche Online-Recherche aber auch die Oracle Press-Bücher, welche mit Prüfungsfragen am Ende jedes Kapitels aufwarten. So spart man sich Zeit und ist trotzdem gut vorbereitet. Auch wenn ich keine Laufbahn als Administrator einschlagen werde, bin ich froh die zugrundeliegende Technologie vieler Anwendungen besser zu verstehen. Für meine tägliche Arbeit als Anwendungsentwickler hat es mir vor allem geholfen, Oracle-Konzepte z.B. im Bereich der Transaktionssteuerung und Wiederherstellung zu verstehen und damit viele Open Source Produkte jetzt sinnvoller bewerten und empfehlen zu können." Eine Übersicht der Zertifizierungspfade finden Sie auf der Oracle University Webseite (dann einfach "Deutschland""auswählen und anschließend auf den Punkt "Zertifizierungen" klicken).

Scrolling an HTML 5 page using JQuery

- by nikolaosk

In this post I will show you how to use JQuery to scroll through an HTML 5 page.I had to help a friend of mine to implement this functionality and I thought it would be a good idea to write a post.I will not use any JQuery scrollbar plugin,I will just use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/download.Please find here all my posts regarding JQuery.Also have a look at my posts regarding HTML 5.In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Let me move on to the actual example.This is the sample HTML 5 page<!DOCTYPE html><html lang="en"> <head> <title>Liverpool Legends</title> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" > <link rel="stylesheet" type="text/css" href="style.css"> <script type="text/javascript" src="jquery-1.8.2.min.js"> </script> <script type="text/javascript" src="scroll.js"> </script> </head> <body> <header> <h1>Liverpool Legends</h1> </header> <div id="main"> <table> <caption>Liverpool Players</caption> <thead> <tr> <th>Name</th> <th>Photo</th> <th>Position</th> <th>Age</th> <th>Scroll</th> </tr> </thead> <tfoot class="footnote"> <tr> <td colspan="4">We will add more photos soon</td> </tr> </tfoot> <tbody> <tr class="maintop"> <td>Alan Hansen</td> <td> <figure> <img src="images\Alan-hansen-large.jpg" alt="Alan Hansen"> <figcaption>The best Liverpool Defender <a href="http://en.wikipedia.org/wiki/Alan_Hansen">Alan Hansen</a></figcaption> </figure> </td> <td>Defender</td> <td>57</td> <td class="top">Middle</td> </tr> <tr> <td>Graeme Souness</td> <td> <figure> <img src="images\graeme-souness-large.jpg" alt="Graeme Souness"> <figcaption>Souness was the captain of the successful Liverpool team of the early 1980s <a href="http://en.wikipedia.org/wiki/Graeme_Souness">Graeme Souness</a></figcaption> </figure> </td> <td>MidFielder</td> <td>59</td> </tr> <tr> <td>Ian Rush</td> <td> <figure> <img src="images\ian-rush-large.jpg" alt="Ian Rush"> <figcaption>The deadliest Liverpool Striker <a href="http://it.wikipedia.org/wiki/Ian_Rush">Ian Rush</a></figcaption> </figure> </td> <td>Striker</td> <td>51</td> </tr> <tr class="mainmiddle"> <td>John Barnes</td> <td> <figure> <img src="images\john-barnes-large.jpg" alt="John Barnes"> <figcaption>The best Liverpool Defender <a href="http://en.wikipedia.org/wiki/John_Barnes_(footballer)">John Barnes</a></figcaption> </figure> </td> <td>MidFielder</td> <td>49</td> <td class="middle">Bottom</td> </tr> <tr> <td>Kenny Dalglish</td> <td> <figure> <img src="images\kenny-dalglish-large.jpg" alt="Kenny Dalglish"> <figcaption>King Kenny <a href="http://en.wikipedia.org/wiki/Kenny_Dalglish">Kenny Dalglish</a></figcaption> </figure> </td> <td>Midfielder</td> <td>61</td> </tr> <tr> <td>Michael Owen</td> <td> <figure> <img src="images\michael-owen-large.jpg" alt="Michael Owen"> <figcaption>Michael was Liverpool's top goal scorer from 1997–2004 <a href="http://www.michaelowen.com/">Michael Owen</a></figcaption> </figure> </td> <td>Striker</td> <td>33</td> </tr> <tr> <td>Robbie Fowler</td> <td> <figure> <img src="images\robbie-fowler-large.jpg" alt="Robbie Fowler"> <figcaption>Fowler scored 183 goals in total for Liverpool <a href="http://en.wikipedia.org/wiki/Robbie_Fowler">Robbie Fowler</a></figcaption> </figure> </td> <td>Striker</td> <td>38</td> </tr> <tr class="mainbottom"> <td>Steven Gerrard</td> <td> <figure> <img src="images\steven-gerrard-large.jpg" alt="Steven Gerrard"> <figcaption>Liverpool's captain <a href="http://en.wikipedia.org/wiki/Steven_Gerrard">Steven Gerrard</a></figcaption> </figure> </td> <td>Midfielder</td> <td>32</td> <td class="bottom">Top</td> </tr> </tbody></table> </div> <footer> <p>All Rights Reserved</p> </footer> </body> </html> The markup is very easy to follow and understand. You do not have to type all the code,simply copy and paste it.For those that you are not familiar with HTML 5, please take a closer look at the new tags/elements introduced with HTML 5.When I view the HTML 5 page with Firefox I see the following result. I have also an external stylesheet (style.css). body{background-color:#efefef;}h1{font-size:2.3em;}table { border-collapse: collapse;font-family: Futura, Arial, sans-serif; }caption { font-size: 1.2em; margin: 1em auto; }th, td {padding: .65em; }th, thead { background: #000; color: #fff; border: 1px solid #000; }tr:nth-child(odd) { background: #ccc; }tr:nth-child(even) { background: #404040; }td { border-right: 1px solid #777; }table { border: 1px solid #777; }.top, .middle, .bottom { cursor: pointer; font-size: 22px; font-weight: bold; text-align: center;}.footnote{text-align:center;font-family:Tahoma;color:#EB7515;}a{color:#22577a;text-decoration:none;} a:hover {color:#125949; text-decoration:none;} footer{background-color:#505050;width:1150px;}These are just simple CSS Rules that style the various HTML 5 tags,classes. The jQuery code that makes it all possible resides inside the scroll.js file.Make sure you type everything correctly.$(document).ready(function() { $('.top').click(function(){ $('html, body').animate({ scrollTop: $(".mainmiddle").offset().top },4000 ); }); $('.middle').click(function(){ $('html, body').animate({ scrollTop: $(".mainbottom").offset().top },4000); }); $('.bottom').click(function(){ $('html, body').animate({ scrollTop: $(".maintop").offset().top },4000); }); }); Let me explain what I am doing here.When I click on the Middle word ( $('.top').click(function(){ ) this relates to the top class that is clicked.Then we declare the elements that we want to participate in the scrolling. In this case is html,body ( $('html, body').animate).These elements will be part of the vertical scrolling.In the next line of code we simply move (navigate) to the element (class mainmiddle that is attached to a tr element.) scrollTop: $(".mainmiddle").offset().top Make sure you type all the code correctly and try it for yourself. I have tested this solution will all 4-5 major browsers.Hope it helps!!!

Ever any performance different between Java >> and >>> right shift operators?

- by Sean Owen

Is there ever reason to think the (signed) and (unsigned) right bit-shift operators in Java would perform differently? I can't detect any difference on my machine. This is purely an academic question; it's never going to be the bottleneck I'm sure. I know: it's best to write what you mean foremost; use for division by 2, for example. I assume it comes down to which architectures have which operations implemented as an instruction.

Does an app name have to be unique between the iPhone and iPad app store?

- by Owen

If there was an iPhone app called 'gears' could I release a app for iPad called 'gears'? Also, has anyone heard if Apple will move towards limiting unique names to a category so it would be possible e.g. 'gears' the game and 'gears' the productivity app? App naming seems like a dark art. Any pointers to resources on Apple's stance would also be handy.

NSMutableArray of Objects

- by Terry Owen

First off I am very new to Objective C and iPhone programming. Now that that is out of the way. I have read through most of the Apple documentation on this and some third party manuals. I guess I just want to know if I'm going about this the correct way ... - (NSMutableArray *)makeModel { NSString *api = @"http://www.mycoolnewssite.com/api/v1"; NSArray *namesArray = [NSArray arrayWithObjects:@"News", @"Sports", @"Entertainment", @"Business", @"Features", nil]; NSArray *urlsArray = [NSArray arrayWithObjects: [NSString stringWithFormat:@"%@/news/news/25/stories.json", api], [NSString stringWithFormat:@"%@/news/sports/25/stories.json", api], [NSString stringWithFormat:@"%@/news/entertainment/25/stories.json", api], [NSString stringWithFormat:@"%@/news/business/25/stories.json", api], [NSString stringWithFormat:@"%@/news/features/25/stories.json", api], nil]; NSMutableArray *result = [NSMutableArray array]; for (int i = 0; i < [namesArray count]; i++) { NSMutableDictionary *objectDict = [NSMutableDictionary dictionary]; NSString *name = (NSString *)[namesArray objectAtIndex:i]; NSString *url = (NSString *)[urlsArray objectAtIndex:i]; [objectDict setObject:name forKey:@"NAME"]; [objectDict setObject:url forKey:@"URL"]; [objectDict setObject:@"NO" forKey:@"HASSTORIES"]; [result addObject:objectDict]; } return result; } Any insight would be appreciated ;-)

Avoiding thumbnail name collisions with sorl-thumbnail

- by Owen Nelson

Understanding that I should probably just dig into the source to come up with a solution, I'm wondering if anyone has come up with a tactic for dealing with this. In my project, I have a lot of images being generated outside of the application. I'm isolating them on the filesystem based on a model's pk. For example, a model instance with a pk of 121 might have the following images: .../thumbs/1/2/1/img.1.jpg .../thumbs/1/2/1/img.2.jpg ... .../thumbs/1/2/1/img.27.jpg Since the image filenames themselves are not guaranteed to be unique, I'm looking for a way to inform sorl (at runtime) that I'd like to prefix thumbs for this model with the instance pk value. Is this even possible without patching sorl?
