  • EHome IR receiver and Ubuntu 13 - any one have this working?

    - by squakie
    I have a "generic" USB IR receiver I purchased off of Ebay to make my life a little easier with XBMC on my Ubuntu box. I am currently running 13.10 and have never tried nor have any knowledge of IR in Ubuntu. I know of lirc, and I know a lot of it is now included in the kernel. My understanding is that lirc in basic terms maps pulses from an remote control to functions - like keyboard or mouse clicks. It is also my understanding that I might still need a driver or something for my device. lsusb shows the device as: Bus 006 Device 003: ID 147a:e016 Formosa Industrial Computing, Inc. eHome Infrared Receiver dmesg shows the following pertaining to the device: [43635.311985] usb 6-2: USB disconnect, device number 2 [43641.344387] usb 6-2: new full-speed USB device number 3 using ohci-pci [43641.543454] usb 6-2: New USB device found, idVendor=147a, idProduct=e016 [43641.543467] usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [43641.543473] usb 6-2: Product: eHome Infrared Transceiver [43641.543478] usb 6-2: Manufacturer: Formosa21 [43641.543483] usb 6-2: SerialNumber: FM000623 [43641.555736] Registered IR keymap rc-rc6-mce [43641.555968] input: Media Center Ed. eHome Infrared Remote Transceiver (147a:e016) as /devices/pci0000:00/0000:00:12.0/usb6/6-2/6-2:1.0/rc/rc2/input15 [43641.556221] rc2: Media Center Ed. eHome Infrared Remote Transceiver (147a:e016) as /devices/pci0000:00/0000:00:12.0/usb6/6-2/6-2:1.0/rc/rc2 [43641.556584] input: MCE IR Keyboard/Mouse (mceusb) as /devices/virtual/input/input16 [43641.557186] rc rc2: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0 [43641.731965] mceusb 6-2:1.0: Registered Formosa21 eHome Infrared Transceiver with mce emulator interface version 1 [43641.731978] mceusb 6-2:1.0: 2 tx ports (0x0 cabled) and 2 rx sensors (0x0 active) (excuse the double spacing, but I had to put in extra cr/lf using "enter" or the entire thing was just one long unreadable string). When I connect the same IR receiver to a Raspberry Pi running OpenELEC/XBMC there is no flashing led unless I press a remote button, and the device works. In Ubuntu, the led is constantly blinking, and nothing happens when I press a remote key. I tried the command line program to test but it never echoes anything back to the terminal window. I believe it must need some sort of driver or something else, but I am completely in the dark on this. If it matters I also have: - Logitech wireless keyboard/mouse USB receiver - Tenda USB wireless adapter And.....I've also noticed some errors now that show in dmesg that seem to somehow related to HDMI if that makes any sense: 46721.144731] HDMI: ELD buf size is 0, force 128 [46721.144749] HDMI: invalid ELD data byte 0 [46721.444025] HDMI: ELD buf size is 0, force 128 [46721.444061] HDMI: invalid ELD data byte 0 [46721.743375] HDMI: ELD buf size is 0, force 128 [46721.743411] HDMI: invalid ELD data byte 0 [46722.043092] HDMI: ELD buf size is 0, force 128 [46722.043118] HDMI: invalid ELD data byte 0 [46722.343086] HDMI: ELD buf size is 0, force 128 [46722.343122] HDMI: invalid ELD data byte 0 [46722.642517] HDMI: ELD buf size is 0, force 128 [46722.642574] HDMI: invalid ELD data byte 0 [46722.942459] HDMI: ELD buf size is 0, force 128 [46722.942485] HDMI: invalid ELD data byte 0 [46723.242103] HDMI: ELD buf size is 0, force 128 [46723.242129] HDMI: invalid ELD data byte 0 [46723.541877] HDMI: ELD buf size is 0, force 128 [46723.541923] HDMI: invalid ELD data byte 0 [58366.651954] HDMI: ELD buf size is 0, force 128 [58366.651980] HDMI: invalid ELD data byte 0 [58366.951523] HDMI: ELD buf size is 0, force 128 [58366.951549] HDMI: invalid ELD data byte 0 [58367.251075] HDMI: ELD buf size is 0, force 128 [58367.251121] HDMI: invalid ELD data byte 0 [58367.550517] HDMI: ELD buf size is 0, force 128 [58367.550563] HDMI: invalid ELD data byte 0 [58367.850219] HDMI: ELD buf size is 0, force 128 [58367.850256] HDMI: invalid ELD data byte 0 [58368.150160] HDMI: ELD buf size is 0, force 128 [58368.150185] HDMI: invalid ELD data byte 0 [58368.449544] HDMI: ELD buf size is 0, force 128 [58368.449570] HDMI: invalid ELD data byte 0 [58368.749583] HDMI: ELD buf size is 0, force 128 [58368.749629] HDMI: invalid ELD data byte 0 [58369.049280] HDMI: ELD buf size is 0, force 128 [58369.049326] HDMI: invalid ELD data byte 0 [58394.706273] HDMI: ELD buf size is 0, force 128 [58394.706300] HDMI: invalid ELD data byte 0 [58394.706350] HDMI: ELD buf size is 0, force 128 [58394.706367] HDMI: invalid ELD data byte 0 [58395.003032] HDMI: ELD buf size is 0, force 128 [58395.003058] HDMI: invalid ELD data byte 0 [58395.302680] HDMI: ELD buf size is 0, force 128 [58395.302705] HDMI: invalid ELD data byte 0 [58395.602442] HDMI: ELD buf size is 0, force 128 [58395.602477] HDMI: invalid ELD data byte 0 [58395.902143] HDMI: ELD buf size is 0, force 128 [58395.902179] HDMI: invalid ELD data byte 0 [58396.201839] HDMI: ELD buf size is 0, force 128 [58396.201875] HDMI: invalid ELD data byte 0 [58396.501538] HDMI: ELD buf size is 0, force 128 [58396.501574] HDMI: invalid ELD data byte 0 [58396.801232] HDMI: ELD buf size is 0, force 128 [58396.801268] HDMI: invalid ELD data byte 0 [58397.100583] HDMI: ELD buf size is 0, force 128 [58397.100627] HDMI: invalid ELD data byte 0 [63095.766042] systemd-hostnamed[8875]: Warning: nss-myhostname is not installed.

  • Mock RequireJS define dependencies with config.map

    - by Aligned
    Originally posted on: http://geekswithblogs.net/Aligned/archive/2014/08/18/mock-requirejs-define-dependencies-with-config.map.aspxI had a module dependency, that I’m pulling down with RequireJS that I needed to use and write tests against. In this case, I don’t care about the actual implementation of the module (it’s simple enough that I’m just avoiding some AJAX calls). EDIT: make sure you look at the bottom example after the edit before using the config.map approach. I found that there is an easier way. I did not want to change the constructor of the consumer as I had a chain of changes that would have to be made and that would have been to invasive for this task. I found a question on StackOverflow with a short, but helpful answer from “Artem Oboturov”. We can use the config.map from RequireJs to achieve this. Here is some code: A module example (“usefulModule” in Common/Modules/usefulModule.js): define([], function() { "use strict"; var testMethod = function() { ... }; // add more functionality of the module return { testMethod; } }); A consumer of usefulModule example: define([ "Commmon/Modules/usefulModule" ], function(usefulModule) { "use strict"; var consumerModule = function(){ var self = this; // add functionality of the module } }); Using config.map in the html of the test runner page (and in your Karma config –> I’m still trying to figure this out): map: {'*': { // replace usefulModule with a mock 'Common/Modules/usefulModule': '/Tests/Specs/Common/usefulModuleMock.js' } } With the new mapping, Require will load usefulModuleMock.js from Tests/Specs/Common instead of the real implementation. Some of the answers on StackOverflow mentioned Squire.js, which looked interesting, but I wasn’t ready to introduce a new library at this time. That’s all you need to be able to mock a depency in RequireJS. However, there are many good cases when you should pass it in through the constructor instead of this approach.   EDIT: After all that, here’s another, probably better way: The consumer class, updated: define([ "Commmon/Modules/usefulModule" ], function(UsefulModule) { "use strict"; var consumerModule = function(){ var self = this; self.usefulModule = new UsefulModule(); // add functionality of the module } }); Jasmine test: define([ "consumerModule", "/UnitTests/Specs/Common/Mocks/usefulModuleMock.js" ], function(consumerModule, UsefulModuleMock){ describe("when mocking out the module", function(){ it("should probably just override the property", function(){ var consumer = new consumerModule(); consumer.usefulModule = new UsefulModuleMock(); }); }); });   Thanks for letting me think out loud :-).

  • git workflow for separating commits

    - by gman
    Best practices with git (or any VCS for that matter) is supposed to be to have each commit do the smallest change possible. But, that doesn't match how I work at all. For example I recently I needed to add some code that checked if the version of a plugin to my system matched the versions the system supports. If not print a warning that the plugin probably requires a newer version of the system. While writing that code I decided I wanted the warnings to be colorized. I already had code that colorized error message so I edited that code. That code was in the startup module of one entry to the system. The plugin checking code was in another path that didn't use that entry point so I moved the colorization code into a separate module so both entry points could use it. On top of that, in order to test my plugin checking code works I need to go edit UI/UX code to make sure it tells the user "You need to upgrade". When all is said and done I've edited 10 files, changed dependencies, the 2 entry points are now both dependant on the colorization code, etc etc. Being lazy I'd probably just git add . && git commit -a the whole thing. Spending 10-15 minutes trying to manipulate all those changes into 3 to 6 smaller commits seems frustrating which brings up the question Are there workflows that work for you or that make this process easier? I don't think I can some how magically always modify stuff in the perfect order since I don't know that order until after I start modifying and seeing what comes up. I know I can git add --interactive etc but it seems, at least for me, kind of hard to know what I'm grabbing exactly the correct changes so that each commit is actually going to work. Also, since the changes are sitting in the current directory it doesn't seem like it would be easy to run tests on each commit to make sure it's going to work short of stashing all the changes. And then, if it were to stash and then run the tests, if I missed a few lines or accidentally added a few too many lines I have no idea how I'd easily recover from that. (as in either grab the missing lines from the stash and then put the rest back or take the few extra lines I shouldn't have grabbed and shove them into the stash for the next commit. Thoughts? Suggestions? PS: I hope this is an appropriate question. The help says development methodologies and processes

  • Control diamond square algorithm to generate islands/pangea.

    - by Gabriel A. Zorrilla
    I generated a height map with the diamond square algorithm. The thing is i do not manage to create islands, this is, restrict the height other than water level range to a certain value in the center of the map. I manualy seeded a circle in the middle of the map but the rest of the map still receives heights over the water level. I dont fully understand the Perlin noise algorithm so i'd like to work with my current implementation of the diamond square algorithm which took me 3 days to interpret and code in PHP. :P

  • Triggers, Service Broker, CDC or Change Tracking?

    - by Derek D.
    When one trigger inserts into a table and that table also contains a trigger, this is a “nested trigger”. The reason that nested triggers are a concern is because the first call that performs the initial insert does not return until the last trigger in sequence is complete. In trying to circumvent this [...]

    - by JuergenKress
    As cloud computing moves out of the early-adopter phase, organizations are carefully evaluating how to get to the cloud. They are examining standard methods for developing, integrating, deploying, and scaling their cloud applications, and after weighing their choices, they are choosing to develop and deploy cloud applications based on Oracle Cloud Application Foundation, part of Oracle Fusion Middleware. Oracle WebLogic Server is the flagship software product of Oracle Cloud Application Foundation. Oracle WebLogic Server is optimized to run on Oracle Exalogic Elastic Cloud, the integrated hardware and software platform for the Oracle Cloud Application Foundation family. Many companies, including Reliance Commercial Finance, are adopting this middleware infrastructure to enable private cloud computing and its convenient, on-demand access to a shared pool of configurable computing resources. “Cloud computing has become an extremely critical design factor for us,” says Shashi Kumar Ravulapaty, senior vice president and chief technology officer at Reliance Commercial Finance. “It’s one of our main focus areas. Oracle Exalogic, especially in combination with Oracle WebLogic, is a perfect fit for rapidly provisioning capacity in a private cloud infrastructure.” Reliance Commercial Finance provides loans to tens of thousands of customers throughout India. With more than 1,500 employees accessing the company’s core business applications every day, the company was having trouble processing more than 6,000 daily transactions with its legacy infrastructure, especially at the end of each month when hundreds of concurrent users need to access the company’s loan processing and approval applications.

  • SWT Layout for absolute positioning with minimal-spanning composites

    - by pure.equal
    Hi, I'm writing a DND-editor where I can position elemtents (like buttons, images ...) freely via absolute positioning. Every element has a parent composite. These composites should span/grasp/embrace every element they contain. There can be two or more elements in the same composite and a composite can contain another composite. This image shows how it should look like. To achive this I wrote a custom layoutmanager: import org.eclipse.swt.SWT; import org.eclipse.swt.graphics.Point; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Control; import org.eclipse.swt.widgets.Layout; public class SpanLayout extends Layout { Point[] sizes; int calcedHeight, calcedWidth, calcedX, calcedY; Point[] positions; /* * (non-Javadoc) * * @see * org.eclipse.swt.widgets.Layout#computeSize(org.eclipse.swt.widgets.Composite * , int, int, boolean) * * A composite calls computeSize() on its associated layout to determine the * minimum size it should occupy, while still holding all its child controls * at their minimum sizes. */ @Override protected Point computeSize(Composite composite, int wHint, int hHint, boolean flushCache) { int width = wHint, height = hHint; if (wHint == SWT.DEFAULT) width = composite.getBounds().width; if (hHint == SWT.DEFAULT) height = composite.getBounds().height; return new Point(width, height); } /* * (non-Javadoc) * * @see * org.eclipse.swt.widgets.Layout#layout(org.eclipse.swt.widgets.Composite, * boolean) * * Calculates the positions and sizes for the children of the passed * Composite, then places them accordingly by calling setBounds() on each * one. */ @Override protected void layout(Composite composite, boolean flushCache) { Control children[] = composite.getChildren(); for (int i = 0; i < children.length; i++) { calcedX = calcX(children[i]); calcedY = calcY(children[i]); calcedHeight = calcHeight(children[i]) - calcedY; calcedWidth = calcWidth(children[i]) - calcedX; if (composite instanceof Composite) { calcedX = calcedX - composite.getLocation().x; calcedY = calcedY - composite.getLocation().y; } children[i].setBounds(calcedX, calcedY, calcedWidth, calcedHeight); } } private int calcHeight(Control control) { int maximum = 0; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedHeight = calcHeight(child); if (calculatedHeight > maximum) { maximum = calculatedHeight; } } return maximum; } } return control.computeSize(SWT.DEFAULT, SWT.DEFAULT, true).y + control.getLocation().y; } private int calcWidth(Control control) { int maximum = 0; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedWidth = calcWidth(child); if (calculatedWidth > maximum) { maximum = calculatedWidth; } } return maximum; } } return control.computeSize(SWT.DEFAULT, SWT.DEFAULT, true).x + control.getLocation().x; } private int calcX(Control control) { int minimum = Integer.MAX_VALUE; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedX = calcX(child); if (calculatedX < minimum) { minimum = calculatedX; } } return minimum; } } return control.getLocation().x; } private int calcY(Control control) { int minimum = Integer.MAX_VALUE; if (control instanceof Composite) { if (((Composite) control).getChildren().length > 0) { for (Control child : ((Composite) control).getChildren()) { int calculatedY = calcY(child); if (calculatedY < minimum) { minimum = calculatedY; } } return minimum; } } return control.getLocation().y; } } The problem with it is that it always positions the composite at the position (0,0). This is because it tries to change the absolute positioning into a relative one. Lets say I position a image at position (100,100) and one at (200,200). Then it has to calculate the location of the composite to be at (100,100) and spanning the one at (200,200). But as all child positions are relative to their parents I have to change the positions of the children to remove the 100px offset of the parent. When the layout gets updated it moves everything to the top-left corner (as seen in the image) because the position of the image is not (100,100) but (0,0) since I tried to remove the 100px offset of the partent. Where is my error in reasoning? Is this maybe a totally wrong approach? Is there maybe an other way to achive the desired behavior? Thanks in advance! Best regards, Ed

  • rsyslog channels change ownership from root

    Hello all I am using rsyslog on ubuntu 10.4 64bit LTS. the following is the relevant config in /etc/rsyslog.d/60-mylogger.conf $template Paul,"%msg%\n" $outchannel log_rotation_paul,/var/log/paul/events.log,2000,/opt/scripts/log_rotation_script.sh local0.* $log_rotation_paul;Paul This should rotate every 2000 bytes My problem is the the channel directive here causes the ownership defined in /etc/rsyslog.conf to be completely ignored and when my log rotate script is called I don't have the root permissions required to move my log file as its the script runs as rsyslog and the file I am moving requires root permissions.

  • Tool to identify potential reviewers for a proposed change

    - by Lorin Hochstein
    Is there a tool that takes as input a proposed patch and a git repository, and identifies the developers are the best candidates for reviewing the patch? It would use the git history to identify the authors that have the most experience with the files / sections of code that are being changed. Edit: The use case is a large open source project (OpenStack Compute), where merge proposals come in, and I see a merge proposal on a chunk of code I'm not familiar with, and I want to add somebody else's name to the list of suggested reviewers so that person gets a notification to look at the merge proposal.

  • 9 Ways Facebook Monetization Could Change Your Marketing

    - by Mike Stiles
    Think Facebook monetization isn’t a head game? Imagine creating something so functional, fun and addictive you literally amass about 1/7th of the planet’s population as an audience. You have 1 billion users that use it at least once a month. But analysts and marketers look at what you’ve done and say, “eh…not good enough.” What if you had a TV show that garnered 1/7 of Earth’s population as an audience? How much would a spot cost? And how fast would marketers write that check, even without the targeting and engagement analytics Facebook offers? Having already changed the marketing landscape forever, if you’re Facebook’s creator, you’d have to be scratching your head and asking, “Wow, what more does a product need to do?” Facebook’s been busy answering that very question with products and betas that will likely directly affect your brand’s strategy. Item 1: Users can send physical gifts to friends through Facebook based on suggestions from user data. A giant step toward the potential power of social commerce. Item 2: Users can pay $7 to promote posts for higher visibility. Individual users, not just marketers, are being leveraged as a revenue stream. Not impressive enough? There’s also the potential Craigslist killer Facebook Marketplace. Item 3: Mobile ads. 600 million+ access Facebook on smartphones. According to the company, half of the $1 million a day generated by Sponsored Stories as of late June was coming from mobile. Ads in News Feeds seen on mobile had click-through rates 23x higher than on desktop News Feeds or the right side panel. Item 4: App developers can buy install ads that show up in mobile News Feeds so reliance on discovery in app stores is reduced. Item 5: Want your posts seen by people who never liked your Page? A test began in August where you could appear in non-fans’ News Feeds on both web and mobile. Item 6: How about an ability to use Facebook data to buy ads outside of Facebook? A mobile ad network is being tested to get your targeted messages on non-Facebook apps and sites surfaced on devices. Item 7: Facebook Collections, Facebook’s answer to Pinterest. Users can gather images of desired products and click through to the retailer to buy. Keep focusing on your imagery. Item 8: Facebook Offers, Facebook’s answer to the Groupons and Living Socials of the world. You can send deals to your fans’ News Feeds. Item 9: Facebook Exchange lets you track what fans do on Facebook and across the entire Web. Could lead to a Facebook ad network leveraging Facebook users and data but not limiting exposure to the Facebook platform. Marketers are seeing increasing value in Facebook (and Twitter for that matter).  But as social grows and adjusts, will marketing budgets aimed in that direction grow and adjust accordingly, and within a reasonable time frame? @mikestilesPhoto Christie Merrill/stock.xchng

  • SQL SERVER – Faster SQL Server Databases and Applications – Power and Control with SafePeak Caching Options

    - by Pinal Dave
    Update: This blog post is written based on the SafePeak, which is available for free download. Today, I’d like to examine more closely one of my preferred technologies for accelerating SQL Server databases, SafePeak. Safepeak’s software provides a variety of advanced data caching options, techniques and tools to accelerate the performance and scalability of SQL Server databases and applications. I’d like to look more closely at some of these options, as some of these capabilities could help you address lagging database and performance on your systems. To better understand the available options, it is best to start by understanding the difference between the usual “Basic Caching” vs. SafePeak’s “Dynamic Caching”. Basic Caching Basic Caching (or the stale and static cache) is an ability to put the results from a query into cache for a certain period of time. It is based on TTL, or Time-to-live, and is designed to stay in cache no matter what happens to the data. For example, although the actual data can be modified due to DML commands (update/insert/delete), the cache will still hold the same obsolete query data. Meaning that with the Basic Caching is really static / stale cache.  As you can tell, this approach has its limitations. Dynamic Caching Dynamic Caching (or the non-stale cache) is an ability to put the results from a query into cache while maintaining the cache transaction awareness looking for possible data modifications. The modifications can come as a result of: DML commands (update/insert/delete), indirect modifications due to triggers on other tables, executions of stored procedures with internal DML commands complex cases of stored procedures with multiple levels of internal stored procedures logic. When data modification commands arrive, the caching system identifies the related cache items and evicts them from cache immediately. In the dynamic caching option the TTL setting still exists, although its importance is reduced, since the main factor for cache invalidation (or cache eviction) become the actual data updates commands. Now that we have a basic understanding of the differences between “basic” and “dynamic” caching, let’s dive in deeper. SafePeak: A comprehensive and versatile caching platform SafePeak comes with a wide range of caching options. Some of SafePeak’s caching options are automated, while others require manual configuration. Together they provide a complete solution for IT and Data managers to reach excellent performance acceleration and application scalability for  a wide range of business cases and applications. Automated caching of SQL Queries: Fully/semi-automated caching of all “read” SQL queries, containing any types of data, including Blobs, XMLs, Texts as well as all other standard data types. SafePeak automatically analyzes the incoming queries, categorizes them into SQL Patterns, identifying directly and indirectly accessed tables, views, functions and stored procedures; Automated caching of Stored Procedures: Fully or semi-automated caching of all read” stored procedures, including procedures with complex sub-procedure logic as well as procedures with complex dynamic SQL code. All procedures are analyzed in advance by SafePeak’s  Metadata-Learning process, their SQL schemas are parsed – resulting with a full understanding of the underlying code, objects dependencies (tables, views, functions, sub-procedures) enabling automated or semi-automated (manually review and activate by a mouse-click) cache activation, with full understanding of the transaction logic for cache real-time invalidation; Transaction aware cache: Automated cache awareness for SQL transactions (SQL and in-procs); Dynamic SQL Caching: Procedures with dynamic SQL are pre-parsed, enabling easy cache configuration, eliminating SQL Server load for parsing time and delivering high response time value even in most complicated use-cases; Fully Automated Caching: SQL Patterns (including SQL queries and stored procedures) that are categorized by SafePeak as “read and deterministic” are automatically activated for caching; Semi-Automated Caching: SQL Patterns categorized as “Read and Non deterministic” are patterns of SQL queries and stored procedures that contain reference to non-deterministic functions, like getdate(). Such SQL Patterns are reviewed by the SafePeak administrator and in usually most of them are activated manually for caching (point and click activation); Fully Dynamic Caching: Automated detection of all dependent tables in each SQL Pattern, with automated real-time eviction of the relevant cache items in the event of “write” commands (a DML or a stored procedure) to one of relevant tables. A default setting; Semi Dynamic Caching: A manual cache configuration option enabling reducing the sensitivity of specific SQL Patterns to “write” commands to certain tables/views. An optimization technique relevant for cases when the query data is either known to be static (like archive order details), or when the application sensitivity to fresh data is not critical and can be stale for short period of time (gaining better performance and reduced load); Scheduled Cache Eviction: A manual cache configuration option enabling scheduling SQL Pattern cache eviction based on certain time(s) during a day. A very useful optimization technique when (for example) certain SQL Patterns can be cached but are time sensitive. Example: “select customers that today is their birthday”, an SQL with getdate() function, which can and should be cached, but the data stays relevant only until 00:00 (midnight); Parsing Exceptions Management: Stored procedures that were not fully parsed by SafePeak (due to too complex dynamic SQL or unfamiliar syntax), are signed as “Dynamic Objects” with highest transaction safety settings (such as: Full global cache eviction, DDL Check = lock cache and check for schema changes, and more). The SafePeak solution points the user to the Dynamic Objects that are important for cache effectiveness, provides easy configuration interface, allowing you to improve cache hits and reduce cache global evictions. Usually this is the first configuration in a deployment; Overriding Settings of Stored Procedures: Override the settings of stored procedures (or other object types) for cache optimization. For example, in case a stored procedure SP1 has an “insert” into table T1, it will not be allowed to be cached. However, it is possible that T1 is just a “logging or instrumentation” table left by developers. By overriding the settings a user can allow caching of the problematic stored procedure; Advanced Cache Warm-Up: Creating an XML-based list of queries and stored procedure (with lists of parameters) for periodically automated pre-fetching and caching. An advanced tool allowing you to handle more rare but very performance sensitive queries pre-fetch them into cache allowing high performance for users’ data access; Configuration Driven by Deep SQL Analytics: All SQL queries are continuously logged and analyzed, providing users with deep SQL Analytics and Performance Monitoring. Reduce troubleshooting from days to minutes with database objects and SQL Patterns heat-map. The performance driven configuration helps you to focus on the most important settings that bring you the highest performance gains. Use of SafePeak SQL Analytics allows continuous performance monitoring and analysis, easy identification of bottlenecks of both real-time and historical data; Cloud Ready: Available for instant deployment on Amazon Web Services (AWS). As you can see, there are many options to configure SafePeak’s SQL Server database and application acceleration caching technology to best fit a lot of situations. If you’re not familiar with their technology, they offer free-trial software you can download that comes with a free “help session” to help get you started. You can access the free trial here. Also, SafePeak is available to use on Amazon Cloud.

  • Did You Know? What settings to always change

    - by Kalen Delaney
    A week ago, I taught my SQL Server 2012 Internals class to a great group of very interactive students. Even though a dozen of them were taking the class remotely, there were still lots of really great questions and and lots of discussion. One of the students asked if I could summarize all the settings that I recommended changing from the default, right out of the box. I said I’d try to put a list together by the end of the week, but I didn’t make it. So I said I would put it together and blog it....(read more)

  • How to change ownership of a domain name from "missing" web designer

    - by Stuart
    Hi, We had a website produced a few years ago with a .ORG domain name. The site hadn't grown with our needs, so we've now got a new .co.uk site. Our intention was to transfer the .org address to the new site on completion. Our new site is to go live soon, but the original .ORG site has gone offline (hosting expired I believe as the expiry date for the .ORG is in 2012) and we now discover that the .ORG domain name is registered to the web designer and not to anyone in our organisation. The WHOIS information gives us the technical contact as discountasp.net. What are the steps we can take here? Our primary concern is getting the name servers changed (the current .ORG address goes nowhere) and ultimately we need to transfer ownership? The organisation in question is a community, non-profit organisation, so our pockets are not deep. Thanks in advance for any help. Stuart.

  • Cox Communications' Strategic Approach to Enterprise User Experience: How Change Management and Usab

    - by Applications User Experience
    Author: Anna Wichansky, Senior Director, Applications User Experience, and Chair, Oracle Usability Advisory Board As part of our work in the User Experience group, our teams often go to Customer events such as the Higher Education User Group (HEUG) conference, Alliance 2010. This year's event was held in San Antonio, Texas, and was attended by hundreds of higher education, government, and public sector users of Oracle applications. The User Assistance team used this opportunity to reach out to customers in the Educational and Government sectors to better understand how their organizations are currently approaching help, messages, and other forms of user assistance. What is User Assistance? For us, user assistance is more than the old books of users' manuals and documentation. User assistance is anything that helps users get their jobs done quickly and efficiently. Instead of expecting users to stop and look through a guide or manual, we have been developing solutions that are embedded within the interface. We know that when people are having difficulty with a task, they want to be able to search efficiently for solutions and collaborate with coworkers. We know that they want to find their answers right there, right then, so that they can get on with their work. In our interviews at Alliance, we wanted to learn what the participants could tell us about what was happening on their campuses and in their institutions. Figure 1. For Oracle User Assistance, it's not just about books any more. So what did we do? Off to Texas, we recruited 10 people from nine different government and education organizations to come to our Oracle User Experience Onsite Usability Labs. We conducted one-hour interviews with these folks and asked them all about User Assistance--what people are doing, what they would like to do, what technologies they are using, what they would like to use, and ultimately what should we as a company be planning for our future products. We used this as an opportunity also to show them some of our design concepts for Fusion User Assistance, our next generation of user assistance based on the best of our user assistance in other products. Figure 2. Interviewing a technical user at Alliance. What we learned... People are not using paper or online manuals anymore. They don't want to see a manual that is written for technical users and that doesn't make sense to the ordinary end user. They really don't want to have to flip through a manual trying to find an answer to their question. Even when the answer might be tailored to their organization, they don't want to dig through documentation. When they need an answer now, they don't have the patience to dig for something that might or might not be clearly written. What does it mean to an organization when users don't want to deal with documentation? In many cases, it means that frustrated users make phone calls to try to find the answers that they need immediately. Phone calls are expensive to an organization and frustrating to the technical support staff who have provided documentation that no one wants to read anymore. If they don't call, they email for help often, and many users are asking for the same information. The bottom line is that if they could get that help immediately in the interface, they wouldn't have to make those calls or send those emails -- and that saves time and money. Our Fusion User Assistance options to customize help and get help for the task immediately were seen as an opportunity by these technical users to build the solutions that their users need and want. Figure 3. Joyce Ohgi and Laurie Pattison of Applications UX. Chicken Fried Steak. That was huge. But then, this was Texas, where we discovered a lot of things come very big. Drinks are served in quart-size glasses and dishes like Chicken Fried Steaks are served on platters not plates. We saw three-pound cinnamon rolls that you down with tea sweet enough to curl your hair. Deep in the heart of Texas, we learned a lot, and we ate even more.
