• Oracle MAA Part 1: When One Size Does Not Fit All

  - by JoeMeeks

  The good news is that Oracle Maximum Availability Architecture (MAA) best practices combined with Oracle Database 12c (see video) introduce first-in-the-industry database capabilities that truly make unplanned outages and planned maintenance transparent to users. The trouble with such good news is that Oracle’s enthusiasm in evangelizing its latest innovations may leave some to wonder if we’ve lost sight of the fact that not all database applications are created equal. Afterall, many databases don’t have the business requirements for high availability and data protection that require all of Oracle’s ‘stuff’. For many real world applications, a controlled amount of downtime and/or data loss is OK if it saves money and effort. Well, not to worry. Oracle knows that enterprises need solutions that address the full continuum of requirements for data protection and availability. Oracle MAA accomplishes this by defining four HA service level tiers: BRONZE, SILVER, GOLD and PLATINUM. The figure below shows the progression in service levels provided by each tier. Each tier uses a different MAA reference architecture to deploy the optimal set of Oracle HA capabilities that reliably achieve a given service level (SLA) at the lowest cost.  Each tier includes all of the capabilities of the previous tier and builds upon the architecture to handle an expanded fault domain. Bronze is appropriate for databases where simple restart or restore from backup is ‘HA enough’. Bronze is based upon a single instance Oracle Database with MAA best practices that use the many capabilities for data protection and HA included with every Oracle Enterprise Edition license. Oracle-optimized backups using Oracle Recovery Manager (RMAN) provide data protection and are used to restore availability should an outage prevent the database from being able to restart. Silver provides an additional level of HA for databases that require minimal or zero downtime in the event of database instance or server failure as well as many types of planned maintenance. Silver adds clustering technology - either Oracle RAC or RAC One Node. RMAN provides database-optimized backups to protect data and restore availability should an outage prevent the cluster from being able to restart. Gold raises the game substantially for business critical applications that can’t accept vulnerability to single points-of-failure. Gold adds database-aware replication technologies, Active Data Guard and Oracle GoldenGate, which synchronize one or more replicas of the production database to provide real time data protection and availability. Database-aware replication greatly increases HA and data protection beyond what is possible with storage replication technologies. It also reduces cost while improving return on investment by actively utilizing all replicas at all times. Platinum introduces all of the sexy new Oracle Database 12c capabilities that Oracle staff will gush over with great enthusiasm. These capabilities include Application Continuity for reliable replay of in-flight transactions that masks outages from users; Active Data Guard Far Sync for zero data loss protection at any distance; new Oracle GoldenGate enhancements for zero downtime upgrades and migrations; and Global Data Services for automated service management and workload balancing in replicated database environments. Each of these technologies requires additional effort to implement. But they deliver substantial value for your most critical applications where downtime and data loss are not an option. The MAA reference architectures are inherently designed to address conflicting realities. On one hand, not every application has the same objectives for availability and data protection – the Not One Size Fits All title of this blog post. On the other hand, standard infrastructure is an operational requirement and a business necessity in order to reduce complexity and cost. MAA reference architectures address both realities by providing a standard infrastructure optimized for Oracle Database that enables you to dial-in the level of HA appropriate for different service level requirements. This makes it simple to move a database from one HA tier to the next should business requirements change, or from one hardware platform to another – whether it’s your favorite non-Oracle vendor or an Oracle Engineered System. Please stay tuned for additional blog posts in this series that dive into the details of each MAA reference architecture. Meanwhile, more information on Oracle HA solutions and the Maximum Availability Architecture can be found at: Oracle Maximum Availability Architecture - Webcast Maximize Availability with Oracle Database 12c - Technical White Paper

• Keeping folder display the same as it was left

  - by Doug

  In Word 2007 (and also on previous versions I have used), when I open folders, they open with icons or a list. I like 'detail' display and change it to that. I like detail because I can see which file is most recent and the size. But the next time I open the same folder, it opens back to icons or list but not details. How can I get it to stay where I left it? Thanks.

• Get Fanatical About Your Followers

  - by Mike Stiles

  In the fourth of our series of discussions with Aberdeen’s Trip Kucera, we touch on what fans of your brand have come to expect in exchange for their fandom. Spotlight: Around the Oracle Social office, we live for football. So when we think of a true “fan” of a brand, something on the level of a football fan is what comes to mind. But are brands trying to invest fans on that same level? Trip: Yeah, if you’re a football fan, this is definitely your time of year. And if you’ve been to any NFL games recently, especially if you hadn’t been for a few years previously, you may have noticed that from the cup holders to in-stadium Wi-Fi, there’s an increasing emphasis being placed on “fan-focused” accommodations. That’s what they’re known as in the stadium business. Spotlight: How are brands doing in that fan-focused arena? Trip: Remember fan is short for “fanatical.” Brands can definitely learn from the way teams have become fanatical about their fans, or in the social media world, their followers. Many companies consider a segment of their addressable social audience as true fans; I’ve even heard the term “super-fans” used. So just as fans know and can tell you nearly everything about their favorite team, our research shows that there’s a lot value from getting to know your social audience—your followers—at a deeper level. Spotlight: So did your research show there’s a lot to be gained by making fandom a two-way street? Trip: Aberdeen’s new social relationship management research suggests that companies should develop capabilities to better analyze their social audience at a more granular level. Countless “ripped from the headlines” examples, from “United Breaks Guitars” to the most recent British Airways social fiasco we talked about a few weeks ago show how social can magnify the impact of a single customer voice. Spotlight: So how do the companies who are executing social most successfully do that? Trip: Leaders, which are the top-performing companies in Aberdeen’s study, are showing the value of identifying and categorizing your social audience. You should certainly treat every customer as if they have 10,000 followers, because they just might, but you can also proactively engage with high-value customer and high-value influencers. Getting back to the football analogy, it’s like how teams strive to give every guest a great experience, but they really roll out the red carpet for those season ticket and luxury box holders. Spotlight: I’m not allowed in luxury boxes, so you’ll have to tell me what that’s like. But what is the brand equivalent of rolling out the red carpet? Trip: Leaders are nearly three times more likely than Followers to have a process in place that identifies key social influencers for engagement, and more than twice as likely to identify customer advocates for social outreach. This is the kind of knowledge that gives companies the ability to better target social messaging and promotions like we talked about in our last discussion, as well as a basis for understanding how to measure the impact of their social media programs. I’ll give you an example. I hosted an event at one of my favorite restaurants recently. I had mentioned them in a Tweet several weeks before the event, and on the day of the event, they Tweeted out that they were looking forward to seeing me that evening for the event. It’s a small thing, but it had a big impact and I’d certainly go back as a result. Spotlight: So what specifically can brands use and look at to determine where their potential super-fans are? Trip: Social graph analysis, which looks at both the demographic/psychographic trends as well as the behavioral connections, can surface important brand value. Aberdeen’s PR and Brand Management research indicated that top-performing companies are more than three times more likely than Followers to both determine demographic trends through social listening (44% vs. 13%), and to identify meaningful customer segments through social (44% vs. 12%). This kind of brand-level insight can complement and enrich traditional market research. But perhaps even more importantly, it can serve as an early warning system for customer experience failures. @mikestilesPhoto: freedigitalphotos.net

• adding a name to existing LN group distribution and new individuals do not receive email

  - by jocelyn suba

  I made a recent edit to an existing group distribution to add a person. I've saved it. I see it in the detail of the group listing but plugging it into an email, the naming convention pops up, but not all people on the distribution actually receive the email. I tried deleting and re-adding the new person. I tried closing out then open up tto the detail, and all names show. How do i solve for this?

• What Counts for a DBA: Skill

  - by drsql

  “Practice makes perfect:” right? Well, not exactly. The reality of it all is that this saying is an untrustworthy aphorism. I discovered this in my “younger” days when I was a passionate tennis player, practicing and playing 20+ hours a week. No matter what my passion level was, without some serious coaching (and perhaps a change in dietary habits), my skill level was never going to rise to a level where I could make any money at the sport that involved something other than selling tennis balls at a sporting goods store. My game may have improved with all that practice but I had too many bad practices to overcome. Practice by itself merely reinforces what we know and what we can figure out naturally. The truth is actually closer to the expression used by Vince Lombardi: “Perfect practice makes perfect.” So how do you get to become skilled as a DBA if practice alone isn’t sufficient? Hit the Internet and start searching for SQL training and you can find 100 different sites. There are also hundreds of blogs, magazines, books, conferences both onsite and virtual. But then how do you know who is good? Unfortunately often the worst guide can be to find out the experience level of the writer. Some of the best DBAs are frighteningly young, and some got their start back when databases were stored on stacks of paper with little holes in it. As a programmer, is it really so hard to understand normalization? Set based theory? Query optimization? Indexing and performance tuning? The biggest barrier often is previous knowledge, particularly programming skills cultivated before you get started with SQL. In the world of technology, it is pretty rare that a fresh programmer will gravitate to database programming. Database programming is very unsexy work, because without a UI all you have are a bunch of text strings that you could never impress anyone with. Newbies spend most of their time building UIs or apps with procedural code in C# or VB scoring obvious interesting wins. Making matters worse is that SQL programming requires mastery of a much different toolset than most any mainstream programming skill. Instead of controlling everything yourself, most of the really difficult work is done by the internals of the engine (written by other non-relational programmers…we just can’t get away from them.) So is there a golden road to achieving a high skill level? Sadly, with tennis, I am pretty sure I’ll never discover it. However, with programming it seems to boil down to practice in applying the appropriate techniques for whatever type of programming you are doing. Can a C# programmer build a great database? As long as they don’t treat SQL like C#, absolutely. Same goes for a DBA writing C# code. None of this stuff is rocket science, as long as you learn to understand that different types of programming require different skill sets and you as a programmer must recognize the difference between one of the procedural languages and SQL and treat them differently. Skill comes from practicing doing things the right way and making “right” a habit.

• Software Raid 10 corrupted superblock after dual disk failure, how do I recover it?

  - by Shoshomiga

  I have a software raid 10 with 6 x 2tb hard drives (raid 1 for /boot), ubuntu 10.04 is the os. I had a raid controller failure that put 2 drives out of sync, crashed the system and initially the os didnt boot up and went into initramfs instead, saying that drives were busy but I eventually managed to bring the raid up by stopping and assembling the drives. The os booted up and said that there were filesystem errors, I chose to ignore because it would remount the fs in read-only mode if there was a problem. Everything seemed to be working fine and the 2 drives started to rebuild, I was sure that it was a sata controller failure because I had dma errors in my log files. The os crashed soon after that with ext errors. Now its not bringing up the raid, it says that there is no superblock on /dev/sda2, even if I assemble manually with all the device names. I also did a memtest and changed the motherboard in addition to everything else. EDIT: This is my partition layout Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0009c34a Device Boot Start End Blocks Id System /dev/sdb1 * 2048 511999 254976 83 Linux /dev/sdb2 512000 3904980991 1952234496 83 Linux /dev/sdb3 3904980992 3907028991 1024000 82 Linux swap / Solaris All 6 disks have the same layout, partition #1 is for raid 1 /boot, partition #2 is for raid 10 far plan, partition #3 is swap, but sda did not have swap enabled EDIT2: This is the output of mdadm --detail /dev/md1 Layout : near=1, far=2 Chunk Size : 64k UUID : a0feff55:2018f8ff:e368bf24:bd0fce41 Events : 0.3112126 Number Major Minor RaidDevice State 0 8 34 0 spare rebuilding /dev/sdc2 1 0 0 1 removed 2 8 18 2 active sync /dev/sdb2 3 8 50 3 active sync /dev/sdd2 4 0 0 4 removed 5 8 82 5 active sync /dev/sdf2 6 8 66 - spare /dev/sde2 EDIT3: I ran ddrescue and it has copied everything from sda except a single 4096 byte sector that I suspect is the raid superblock EDIT4: Here is some more info too long to fit here lshw: http://pastebin.com/2eKrh7nF mdadm --detail /dev/sd[abcdef]1 (raid1): http://pastebin.com/cgMQWerS mdadm --detail /dev/sd[abcdef]2 (raid10): http://pastebin.com/V5dtcGPF dumpe2fs of /dev/sda2 (from the ddrescue cloned drive): http://pastebin.com/sp0GYcJG I tried to recreate md1 based on this info with the command mdadm --create /dev/md1 -v --assume-clean --level=10 --raid-devices=6 --chunk=64K --layout=f2 /dev/sda2 missing /dev/sdc2 /dev/sdd2 missing /dev/sdf2 But I can't mount it, I also tried to recreate it based on my initial mdadm --detail /dev/md1 but it still doesn't mount It also warns me that /dev/sda2 is an ext2fs file system but I guess its because of ddrescue

• Multitenancy in SQL Azure

  - by cibrax

  If you are building a SaaS application in Windows Azure that relies on SQL Azure, it’s probably that you will need to support multiple tenants at database level. This is short overview of the different approaches you can use for support that scenario, A different database per tenant A new database is created and assigned when a tenant is provisioned. Pros Complete isolation between tenants. All the data for a tenant lives in a database only he can access. Cons It’s not cost effective. SQL Azure databases are not cheap, and the minimum size for a database is 1GB.  You might be paying for storage that you don’t really use. A different connection pool is required per database. Updates must be replicated across all the databases You need multiple backup strategies across all the databases Multiple schemas in a database shared by all the tenants A single database is shared among all the tenants, but every tenant is assigned to a different schema and database user. Pros You only pay for a single database. Data is isolated at database level. If the credentials for one tenant is compromised, the rest of the data for the other tenants is not. Cons You need to replicate all the database objects in every schema, so the number of objects can increase indefinitely. Updates must be replicated across all the schemas. The connection pool for the database must maintain a different connection per tenant (or set of credentials) A different user is required per tenant, which is stored at server level. You have to backup that user independently. Centralizing the database access with store procedures in a database shared by all the tenants A single database is shared among all the tenants, but nobody can read the data directly from the tables. All the data operations are performed through store procedures that centralize the access to the tenant data. The store procedures contain some logic to map the database user to an specific tenant. Pros You only pay for a single database. You only have a set of objects to maintain and backup. Cons There is no real isolation. All the data for the different tenants is shared in the same tables. You can not use traditional ORM like EF code first for consuming the data. A different user is required per tenant, which is stored at server level. You have to backup that user independently. SQL Federations A single database is shared among all the tenants, but a different federation is used per tenant. A federation in few words, it’s a mechanism for horizontal scaling in SQL Azure, which basically uses the idea of logical partitions to distribute data based on certain criteria. Pros You only have a single database with multiple federations. You can use filtering in the connections to pick the right federation, so any ORM could be used to consume the data. Cons There is no real isolation at that database level. The isolation is enforced programmatically with federations.

• iPad: SplitView does not rotate

  - by raj.tiwari

  I have the following setup: A subclass of UISplitViewController that creates the master and detail view controllers in the constructor. Master and Detail view controllers that both override shouldAutorotateToInterfaceOrientation to return `YES'. Detail view controller implements the UISplitViewControllerDelegate protocol and deals with the popover. I am observing two weird issues that might be interrelated: When the split view comes up (in portrait mode - default on simulator), the Master view is visible. It should not be. When I rotate the simulator, the view does not "right" itself. My UISplitViewController subclass does not override shouldAutorotateToInterfaceOrientation. However, both master and details view controllers do and return YES. Any ideas what I might be doing wrong? Is this a simulator bug? Thanks. -Raj

• How to generate simple Packing List with MySQL ?

  - by Stephen

  Hi, I need help on how to create a packing list of a shipment with MySQL. Let's say i have 32 boxes of keyboard ready to ship, the master carton can contain 12 boxes. I only have value 32 boxes and volume of 12. The other value in result below is generated by sql command. Not coming from record. So this easily calculate that the number of master carton would be 3 master cartons, with one as a non-standard quantity. How to perform query on this ? As i would like to be this result: +----------+---------------+-------------------+--------+------------+---------+ | Quantity | Standard_Qty | Non_Standard_Qty | Box_N | Box_Total | RowType | +----------+---------------+-------------------+--------+------------+---------+ | 12 | 1 | 0 | 1 | 3 | Detail | | 12 | 1 | 0 | 2 | 3 | Detail | | 8 | 0 | 1 | 3 | 3 | Detail | | 32 | 2 | 1 | | | Summary | +----------+---------------+-------------------+--------+------------+---------+ It looks like two query i know and probably the use of FLOOR command, in which i was teach in here. How to make this result? Thanks in advance. Stephen

• C# Dictionary as a ListBox.DataSource

  - by Steve H.

  I am trying to bind a dictionary as a DataSource to a ListBox. The solution in How to bind a dicationary to a ListBox in winforms will not work for me because my dictionary is a class-level variable and not a method-level variable, so I can not use var. When you put a class-level variable into new BindingSource(...) with null as the second argument I get an ArgumentNull exception. How do I bind a class-level dictionary as a data source for a list box? I don't like the List< KeyValuePair< string, string work-around becuase Where(...) and First(...) are ugly, complicated, and confusing compared to TryGetValue(...) and other Dictionary functionality.

• Does Google Maps API v3 allow larger zoom values ?

  - by Dr1Ku

  If you use the satellite GMapType using this Google-provided example in v3 of the API, the maximum zoom level has a scale of 2m / 10ft , whereas using the v2 version of another Google-provided example (had to use another one since the control-simple doesn't have the scale control) yields the maximum scale of 20m / 50ft. Is this a new "feature" of v3 ? I have to mention that I've tested the examples in the same GLatLng regions - so my guess is that tile detail level doesn't influence it, am I mistaken ? As mentioned in another question, v3 is to be considered of very Labs-y/beta quality, so use in production should be discouraged for the time being. I've been drawn to the subject since I have to "increase the zoom level of a GMap", the answers here seem to suggest using GTileLayer, and I'm considering GMapCreator, although this will involve some effort. What I'm trying to achieve is to have a larger zoom level, a scale of 2m / 10ft would be perfect, I have a map where the tiles aren't that hi-res and quite a few markers. Seeing that the area doesn't have hi-res tiles, the distance between the markers is really tiny, creating some problematic overlapping. Or better yet, how can you create a custom Map which allows higher zoom levels, as by the Google Campus, where the 2m / 10ft scale is achieved, and not use your own tileserver ? I've seen an example on a fellow Stackoverflower's GMaps sandbox , where the tiles are manually created based on the zoom level. I don't think I'm making any more sense, so I'm just going to end this big question here, I've been wondering around trying to find a solution for hours now. Hope that someone comes to my aid though ! Thank you in advance !

• WPF, TreeView bug, can't select root item after item removed from treeview

  - by user275587

  I have a very weird bug in a three level deep TreeView. It is intermittent and I can't find how to reproduce it consistently. After programmatically removing, adding then removing some third level items, when I click on the root item it isn't selected. It can still expand/collapse but can't be selected with a mouse click and it doesn't fire ItemSelectionChange event. You can click to select a second level or third level items and after that you're finally able to select the root item. I've tried to set IsSelected = false for all items after removing and tried to do a nice clean-up when removing items but it doesn't help. Did anybody run into that bug? Do you have any suggestions to remove this bug?

• NSXMLParser: how do I wait until loading has finished?

  - by Archagon

  Let's say I'm using NSXMLParser to load a level (stored as an XML document, obviously) into my iPhone game. NSXMLParser works by assigning a delegate and sending it messages at key moments. How do I ensure that my entire level is loaded before doing anything else? I know I can make my main class the delegate and implement parserDidEndDocument, but this feels very hacky. My main class shouldn't have to know anything about the way the parsing is done! On the other hand, if I make a separate class/delegate for parsing my level, my main class has no way of knowing when the parsing is finished, unless it queries the parsing class continuously or the parsing class sends it a message. Either way, the main class would be tied to the implementation of the parsing class. Can I hide all this event-driven business from the main class and simply make the parser return the level object when it's done? (i.e., newLevel = [[GameLevel alloc] initFromXML:xmlfile], which would in turn use NSXMLParser to load the level and then somehow return when finished.) At the moment, I'm using an external DOM parser, but I'm curious how this would be done with NSXMLParser. Sorry if this is a stupid question -- I'm a bit new to this!

• Spring MVC defaultValue for Double

  - by mlathe

  Hi All, I'm trying to build a controller like this: @RequestMapping(method = {RequestMethod.GET}, value = "/users/detail/activities.do") public View foo(@RequestParam(value = "userCash", defaultValue="0.0") Double userCash) { System.out.println("foo userCash=" + userCash); } This works fine: http://localhost/app/users/detail/activities.do?userCash=123& but in this one userCash==null despite the default value http://localhost/app/users/detail/activities.do?userCash=& From some digging it seems like the first one works b/c of a Editor binding like this: binder.registerCustomEditor(Double.class, new CustomNumberEditor(Double.class, false)); The trouble is that the second param (ie false) defines whether blank values are allowed. If i set that to true, than the system considers the blank input as valid so i get a null Double class. If i set it to false then the system chokes on the blank input string with: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'double'; nested exception is java.lang.NumberFormatException: empty String Does anyone know how to get the defaultValue to work for Doubles? Thanks --Matthias

• Updating records with their subordinates via CTE or subquery

  - by Mike Jolley

  Let's say I have a table with the following columns: Employees Table employeeID int employeeName varchar(50) managerID int totalOrganization int managerID is referential to employeeID. totalOrganization is currently 0 for all records. I'd like to update totalOrganization on each row to the total number of employees under them. So with the following records: employeeID employeeName managerID totalOrganization 1 John Cruz NULL 0 2 Mark Russell 1 0 3 Alice Johnson 1 0 4 Juan Valdez 3 0 The query should update the totalOrganizations to: employeeID employeeName managerID totalOrganization 1 John Cruz NULL 3 2 Mark Russell 1 0 3 Alice Johnson 1 1 4 Juan Valdez 3 0 I know I can get somewhat of an org. chart using the following CTE: WITH OrgChart (employeeID, employeeName,managerID,level) AS ( SELECT employeeID,employeeName,0 as managerID,0 AS Level FROM Employees WHERE managerID IS NULL UNION ALL SELECT Employees.employeeID,Employees.employeeName,Employees.managerID,Level + 1 FROM Employees INNER JOIN OrgChart ON Employees.managerID = OrgChart.employeeID ) SELECT employeeID,employeeName,managerID, level FROM OrgChart; Is there any way to update the Employees table using a stored procedure rather than building some routine outside of SQL to parse through the data?

• Using LINQ Group By to return new XElements

  I have the following code and got myself confused: I have a query that returns a set of records that have been identified as duplicates and I then want to create a XElement for each one. This should be done in one query I think but I'm now lost. var f = (from x in MyDocument.Descendants("RECORD") where itemsThatWasDuplicated.Contains((int)x.Element("DOCUMENTID")) group x by x.Element("DOCUMENTID").Value into g let item = g.Skip(1) //Ignore first as that is the valid one select item ); var errorQuery = (from x in f let sequenceNumber = x.Element("DOCUMENTID").Value let detail = "Sequence number " + sequenceNumber + " was read more than once" select new XElement("ERROR", new XElement("DATETIME", time), new XElement("DETAIL", detail), new XAttribute("TYPE", "DUP"), new XElement("ID", x.Element("ID").Value) ) );

• How to preselect nodes using jsTree jQuery plug-in

  - by Ed Schembor

  I am using the jsTree jQuery plug-in with its "Checkbox" plug-in and using an async http request to lazy-load each level of the tree. All works great, except that I cannot get the tree to pre-select certain nodes after the first level. I am using the "selected" attribute to provide an array of ID's to preselect. ID's in the top level of the tree are correctly pre-selected. However, ID's in lower levels of the tree are not selected when the level loads. Am I missing something? Here is the constructor code: $(sDivID).tree( { data : { async : true, opts : {url : sURL} }, plugins:{ "checkbox" : {three_state : false} }, selected : myArrayOfIDs, ui:{ theme_name : "checkbox", dots : false, animation : 400 }, callback : { beforedata : function(NODE, TREE_OBJ) { return { id : $(NODE).attr("id") || 0, rand : Math.random().toString() } } } } )

• Loops inside loops

  - by cozzy

  Hi, I'd like to find easier way to write loops inside loops. Here is example code of 3 levels of 'for' loops: int level = 0; int value = 0; bool next = false; for (int i0 = 0; i0 < 6; i0++) { level = 0; value = i0; method(); if (next) for (int i1 = 0; i1 < 6; i1++) { level = 1; value = i1; method(); if (next) for (int i2 = 0; i2 < 6; i2++) { level = 2; value = i2; method(); if (next) { //Do somethnig } } } } private void method() { //use int 'level' and 'value' //determine bool 'next' } I wonder if it's possible to write the same thing different way. To set number of levels(number of loops) and loop repeats. In this case levels = 3; repeats = 6;. I need it because I am using more than 20 loops inside themselves and than the code is not comprehensible. I hope my explanation was ok and thanks for help.

• SQLCMD Restore works in Management Studio but not from DOS prompt

  - by Gautam

  Any idea why my Restore command works fine when run in Management Studio 2008 but not when run from the dos prompt? Shown below is the error when running from the dos prompt.

I can't figure it out. Any ideas?

• What is the practical difference between transport and message reliability in WCF?

  - by mrlane

  I am looking at differences between using WPF in .NET or using Silverlight 4 for the GUI front end of an app that connects to WCF services. I have read that net.tcp binding in Silverlight 4 only supports transport level reliability. With a WPF desktop app we can use message level reliability. What is the actual difference? If transport level reliability ensures that all TCP packets get through, doesnt that also mean that all WCF SOAP messages will also get through?

  I found this script below online, and I'm wondering how I can do the same thing with a Ruby on Rails setup. So, first off, I ran this command: rails g model Node node_id:integer title:string Given this set up, how can I make a tree from a tabbed string like the following? <?php // Make sure to have "Academia" be root node with nodeID of 1 $data = " Social sciences Anthropology Biological anthropology Forensic anthropology Gene-culture coevolution Human behavioral ecology Human evolution Medical anthropology Paleoanthropology Population genetics Primatology Anthropological linguistics Synchronic linguistics (or Descriptive linguistics) Diachronic linguistics (or Historical linguistics) Ethnolinguistics Sociolinguistics Cultural anthropology Anthropology of religion Economic anthropology Ethnography Ethnohistory Ethnology Ethnomusicology Folklore Mythology Political anthropology Psychological anthropology Archaeology ...(goes on for a long time) "; //echo "Checkpoint 2\n"; $lines = preg_split("/\n/", $data); $parentids = array(0 => null); $db = new PDO("host", 'username', 'pass'); $sql = 'INSERT INTO `TreeNode` SET ParentID = ?, Title = ?'; $stmt = $db->prepare($sql); foreach ($lines as $line) { if (!preg_match('/^([\s]*)(.*)$/', $line, $m)) { continue; } $spaces = strlen($m[1]); //$level = intval($spaces / 4); //assumes four spaces per indent $level = strlen($m[1]); // if data is tab indented $title = $m[2]; $parentid = ($level > 0 ? $parentids[$level - 1] : 1); //All "roots" are children of "Academia" which has an ID of "1"; $rv = $stmt->execute(array($parentid, $title)); $parentids[$level] = $db->lastInsertId(); echo "inserted $parentid - " . $parentid .

• Unix RPC programming

  - by Abhi

  Heyy all, I needed some help with ONC RPC programming. My task is to create two-tier client-server architecture wherein one main server (something like a directory) keeps a track of level-two servers and acts as a lookup; the level-two servers exposing some trivial functions, and finally, the clients for level-two servers. The clients ask the directory where a server is located, and then communicate with it. Using RPCGEN, we can create a pair of client-server code; however, the clients in this case need to have stubs for the directory as well as the level-two functions. Being a newbie to RPC, I'm having trouble conceptualizing the way I should code this. How can I call a function from a different server if a client is generated using a different IDL ? Any pointers would be appreciated :) Regards, Abhi
