  • Scanner Dayly Duty Cycle

    - by Juanp
    I'm comfused with the concept of 'Daily Duty Cycle'. For example if I have a scanner that the spec is: PPM (pages per minute): 90 and DDC (Daily Duty Cycle): 800. and I am interested in scanning ONLY 10hours continuously, what would it be the best choice: 90 * 60 * 10 = 54.000 or (800 / 24) * 10 = 333 It is very different results. what would it be the best option?

  • In-Page RSS Reader (Flash? Javascript?)

    - by Jonathan Sampson
    Has anybody ever seen any (no-installs-necessary) solutions to listing any RSS feed on any page of a website? Ideally it would consist of HTML (javascript if necessary) and require no downloads or installs. I am thinking of twitter-style apps that you load up in an iframe or via Javascript and in turn they show your latest tweets on the page - same concept, different content. Just looking for a shiny gadget, not able to write my own solution for this particular project.

  • Enable ReadyBoost on a second internal HDD?

    - by kd304
    I have two SATA HDDs in my desktop PC (one for daily activity, one for storage and backup). I can finely use ReadyBoost with pendrives, but I wonder, Is there a way I could use my underutilized second HDD to participate in the cacheing mechanism (same concept as having two CPU cores crunch things in parallel: have two HDDs fetch data in parallel)? Clearly speaking: I want to enable ReadyBoost on my separate D: drive.

  • Practical way to implement prevention of IP Spoofing

    - by user1369975
    I am an undergraduate Computer Science student and was hoping to gain some knowledge of ways to help prevent IP spoofing but all the resources I have tried out elaborate this concept in a theoretical way. I want to try out my hands at one of the techniques like: http://en.wikipedia.org/wiki/Port_knocking http://en.wikipedia.org/wiki/SYN_cookies How do I simulate this whole situation in my own system were I myself am the attacker and I myself have to defend it? And once I have gained an understanding of it, then how do I start translating that into programming terms?

  • Try and catch error trapping. why is it so significant

    - by oded
    sorry if it sounds dumb ' as i am i a process of learnning java i try to understand , why on earth i should "try" a method to catch errors. it looks to me like the concept is:- ' letting a process run assuming its not properly developed. should i always assume that a program based on classes and inheritance is bound for unexpected errors, which i should handle with such a heavy tools like try catch throw throws ? should all java programs be included withing try catch framework? Thanks Oded.

  • Ask How-To Geek: Dropbox in the Start Menu, Understanding Symlinks, and Ripping TV Series DVDs

    - by Jason Fitzpatrick
    This week we take a look at how to incorporate Dropbox into your Windows Start Menu, understanding and using symbolic links, and how to rip your TV series DVDs right to unique and high-quality episode files. Once a week we dip into our reader mailbag and help readers solve their problems, sharing the useful solutions with you in the process. Read on to see our fixes for this week’s reader dilemmas. Add Drobox to Your Start Menu Dear How-To Geek, I use Dropbox all the time and would like to add it right onto my start menu along side the other major shortcuts like Documents, Pictures, etc. It seems like adding Dropbox into the menu should be part of the Dropbox installation package! Sincerely, Dropboxing in Des Moines Dear Dropboxing, We agree, it would be a nice installation option. As it stands you’re going to have to do a little simple hacking to get Dropbox nestled neatly into your start menu. The hack isn’t super elegant but when you’re done you’ll have the link you want and it’ll look like it was there all along. Check out this step-by-step guide here in order to take an existing Library shortcut and rework it to be a Dropbox link. Understanding and Using Symbolic Links Dear How-To Geek, I was talking to a coworker the other day about an issue I’d been having with a media center application I’m running. He suggested using symbolic links to better organize my media and make it easier for the application to access my collection. I had no idea what he was talking about and never got a chance to bug him about it later. Can you clear up this whole symbolic links business for me? I’ve been using computers for years and I’ve never even heard of it! Sincerely, Symbolic Who? Dear Symbolic, Symbolic links aren’t commonly used by many Windows users which is why you likely haven’t run into the concept. Symbolic links are essentially supercharged shortcuts—the newly introduced Windows library system is really just a type of symbolic link system. You can use symbolic links to do all sorts of neat stuff like link folders to your Dropbox folder, organize media, and more. The concept of symbolic links is pretty simple but the execution can be really tricky. We’d suggest reading over our guide to creating symbolic links in Windows 7, Windows XP, and Ubunutu to get a clearer idea what you’re getting into. Rip Your TV DVDs into Handy Episode Files Dear How-To Geek, My wife got me an iPod for Christmas and I still haven’t got around to filling it up. I have tons of entire TV show seasons on DVD and would like to get them on the iPod but I have absolutely no idea where to start. How do I get the shows off the discs? I thought it would be as easy to import the TV shows into iTunes as it is to import tracks off a CD but I was totally wrong. I tried downloading some applications to rip them but those didn’t work at all. Very frustrating! Surely there is an easy and/or automated way to do this, right? Sincerely, Free My DVDs Dear DVDs, Oh man is this a frustration we can relate to. It’s inordinately difficult to get movies and TV shows off physical media and into digital (and portable media player-friendly) formats. There are a multitude of ways to rip DVDs and quite a few applications out there (some good, some mediocre, and some outright malware). We’d recommend a two-part punch to solve your ripping woes. You’ll need a copy of DVDFab to strip away the protections on the discs and rip the disc and Handbrake to load the disc image and convert the files. It’s not quite as smooth as the CD-to-iTunes workflow but it’s still pretty easy. Check out all the steps and settings you’ll want to toggle here. Have a question you want to put before the How-To Geek staff? Shoot us an email at [email protected] and then keep an eye out for a solution in the Ask How-To Geek column.

  • New Rules of Retail

    - by David Dorf
    I've been on vacation and preparing for Crosstalk, so its been a while since I've posted. I've seen the agenda, and I can assure you Crosstalk will be lots of fun. In addition to hearing from lots of retailers, we'll also be doing a little bowling and racing on the track. I'll be around for the sessions, the ORUG meetings, and our Customer Advisory Board so please be sure to say hello. I also just completed a white paper based on a previous blog posting which in turn was based on learnings from reading What Would Google Do? For each of Jarvis' ten rules, I discuss the concept in the context of retail and provide real-world examples. No mention of products or sales pitches at all. You can download the paper here. It will put you in the right frame of mind for hearing Jeff Jarvis speak at Crosstalk. For those that can't make it, I'll post some highlights afterwards.

  • Flash/Flex/Air and iOS

    - by David Archer
    I'm just a little confused with all of the news recently regarding the cancellation of mobile flash, so was hoping for a little help. I've had a search through and can't find the answers to these questions, so any help would be great. First up, I'm looking to create a game in Flash first, to test whether the concept works as a fun game (on Newgrounds/Kongregate/Facebook etc.). Would it be best to use Flash CS5.5, or Flash Builder? Secondly, with mobile flash now being discontinued by Adobe, could I still port this game over to iOS through the Flash platform, or would it be better at that point to re-write the whole game using Objective C? (NOTE: I'm not an Objective C developer, but am instead a Javascript and Actionscript dev). Any help would be great. Thanks!

  • Fast Fashion Freshness

    - by David Dorf
    Fashion retailers such as H&M, Zara, and Wet Seal have perfected the fast fashion retailing model. The concept requires no replenishment in order to maintain assortment freshness and to create a sense of urgency for the consumer to purchase now. However, maintaining assortment freshness results in high product turnover, making markdown optimization a necessity. Wet Seal, for instance, needed to move from ad-hoc markdowns and dealing with surplus inventory to handling markdowns methodically across 8,000 SKUs with only 12-15 week lifecycle (from DC receipt to exit). By optimizing and automating markdowns, Wet Seal is reaching their goal of assortment freshness, which in turn increases sales. If you're interested in learning more, register for a free webinar occurring on May 13th featuring Join Daniel Ryu, Vice President of Planning and Allocation at Wet Seal. He'll be discussing how the fast fashion retailer maintains their goal of assortment freshness.

  • Unity 3D game idea for a fun and teaching game

    - by rasheeda
    I have been brainstorming for months now on writing a unity 3D game for my final year computer science project. I have been learning unity for sometime now but comming up with a concept is quite difficult than i thought. The game has to be really fun and also educational, one that the school and community can benefit from. I am thinking about a third person game. where the player runs round in an enviroment, picks up coins and earn points. This alone wouldn't earn me points and I have been trying to find new ideas of my own and all over the net but to no avail. Hopefully you guys can help me out with an idea, and how to make the lecturers appreciate the game and also make kids wanna play play it for a reason. Thanks.

  • SQL SERVER – SSMS: Memory Usage By Memory Optimized Objects Report

    - by Pinal Dave
    At conferences and at speaking engagements at the local UG, there is one question that keeps on coming which I wish were never asked. The question around, “Why is SQL Server using up all the memory and not releasing even when idle?” Well, the answer can be long and with the release of SQL Server 2014, this got even more complicated. This release of SQL Server 2014 has the option of introducing In-Memory OLTP which is completely new concept and our dependency on memory has increased multifold. In reality, nothing much changes but we have memory optimized objects (Tables and Stored Procedures) additional which are residing completely in memory and improving performance. As a DBA, it is humanly impossible to get a hang of all the innovations and the new features introduced in the next version. So today’s blog is around the report added to SSMS which gives a high level view of this new feature addition. This reports is available only from SQL Server 2014 onwards because the feature was introduced in SQL Server 2014. Earlier versions of SQL Server Management Studio would not show the report in the list. If we try to launch the report on the database which is not having In-Memory File group defined, then we would see the message in report. To demonstrate, I have created new fresh database called MemoryOptimizedDB with no special file group. Here is the query used to identify whether a database has memory-optimized file group or not. SELECT TOP(1) 1 FROM sys.filegroups FG WHERE FG.[type] = 'FX' Once we add filegroup using below command, we would see different version of report. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILEGROUP [IMO_FG] CONTAINS MEMORY_OPTIMIZED_DATA GO The report is still empty because we have not defined any Memory Optimized table in the database.  Total allocated size is shown as 0 MB. Now, let’s add the folder location into the filegroup and also created few in-memory tables. We have used the nomenclature of IMO to denote “InMemory Optimized” objects. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILE ( NAME = N'MemoryOptimizedDB_IMO', FILENAME = N'E:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\MemoryOptimizedDB_IMO') TO FILEGROUP [IMO_FG] GO You may have to change the path based on your SQL Server configuration. Below is the script to create the table. USE MemoryOptimizedDB GO --Drop table if it already exists. IF OBJECT_ID('dbo.SQLAuthority','U') IS NOT NULL DROP TABLE dbo.SQLAuthority GO CREATE TABLE dbo.SQLAuthority ( ID INT IDENTITY NOT NULL, Name CHAR(500)  COLLATE Latin1_General_100_BIN2 NOT NULL DEFAULT 'Pinal', CONSTRAINT PK_SQLAuthority_ID PRIMARY KEY NONCLUSTERED (ID), INDEX hash_index_sample_memoryoptimizedtable_c2 HASH (Name) WITH (BUCKET_COUNT = 131072) ) WITH (MEMORY_OPTIMIZED = ON, DURABILITY = SCHEMA_AND_DATA) GO As soon as above script is executed, table and index both are created. If we run the report again, we would see something like below. Notice that table memory is zero but index is using memory. This is due to the fact that hash index needs memory to manage the buckets created. So even if table is empty, index would consume memory. More about the internals of how In-Memory indexes and tables work will be reserved for future posts. Now, use below script to populate the table with 10000 rows INSERT INTO SQLAuthority VALUES (DEFAULT) GO 10000 Here is the same report after inserting 1000 rows into our InMemory table.    There are total three sections in the whole report. Total Memory consumed by In-Memory Objects Pie chart showing memory distribution based on type of consumer – table, index and system. Details of memory usage by each table. The information about all three is taken from one single DMV, sys.dm_db_xtp_table_memory_stats This DMV contains memory usage statistics for both user and system In-Memory tables. If we query the DMV and look at data, we can easily notice that the system tables have negative object IDs.  So, to look at user table memory usage, below is the over-simplified version of query. USE MemoryOptimizedDB GO SELECT OBJECT_NAME(OBJECT_ID), * FROM sys.dm_db_xtp_table_memory_stats WHERE OBJECT_ID > 0 GO This report would help DBA to identify which in-memory object taking lot of memory which can be used as a pointer for designing solution. I am sure in future we will discuss at lengths the whole concept of In-Memory tables in detail over this blog. To read more about In-Memory OLTP, have a look at In-Memory OLTP Series at Balmukund’s Blog.

  • JPA/EclipseLink multitenancy screencast

    - by alexismp
    I find JPA and in particular EclipseLink 2.3 to be particularly well suited to illustrate the concept of multitenancy, one of the key PaaS features en route for Java EE 7. Here's a short (5-minute) screencast showing GlassFish 3.1.1 (due out real soon now) and its EclipseLink 2.3 JPA provider showing multitenancy in action. In short, it adds EclipseLink annotations to a JPA entity and deploys two identical applications with different tenant-id properties defined in the persistence.xml descriptor. Each application only sees its own data, yet everything is stored in the same table which was augmented with a discriminator column. For more advanced uses such as tenant property being set on the @PersistenceContext, XML configuration of multitenant JPA entities, and more check out the nicely written wiki page.

  • Code excavations, wishful invocations, perimeters and domain specific unit test frameworks

    One of the talks I did at QCON London was about a subject that Ive come across fairly recently , when I was building SilverUnit a pure unit test framework for silverlight objects that depend on the silverlight runtime to run. It is the concept of cogs in the machine when your piece of code needs to run inside a host framework or runtime that you have little or no control over for testability related matters. Examples of such cogs and machines can be: your custom control running inside silverlight...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How to submit sitemap when your website has partial https? - Error: "Not in Domain"

    - by Ralph N
    My website is an ecommerce that is set up to do http for the item browsing portion, but https for things like shopping cart, contact us, etc.. (anything that has forms on it). I've submitted my website a long time ago to google webmaster tools as http://www.mywebsite.com. I also submitted a sitemap with about 40 links - 8 of them are https. I've noticed that for the longest time, google webmaster tools was reporting that 32 out of the 40 links have been crawled. I tested all the links against my robots.txt and realized that my robots text was blocking the https links. Google says those links are "Not In Domain". Is there a way i'm supposed to get around this so that I can have a hybrid-ssl site? I understand the concept that one site is mywebsite.com:80 and the other is mywebsite.com:443, but i'd like to avoid submitting and maintaining 2 seperate websites on google webmaster tools.

  • SOA, Empowerment and Continuous Improvement

Prior to joining Oracle, Rick held a variety of executive operational positions at Corning, Inc. and Bausch & Lomb. With a professional background that includes senior management positions in manufacturing, supply chain and information technology, Rick brings a unique set of experiences to cover the impact that technology can have on business models, processes and organizations. Rick will be hosting the IT Leader Editorial on a regular basis. I met my twin at Open World. We share backgrounds, experiences and even names. I hosted an invitation-only AppAdvantage Leadership Forum with an overcapacity 85 participants: 55 customers, 15 from the Oracle AppAdvantage team and 15 Partners. It was a lively, open and positive discussion of pace layered architectures and Oracle’s AppAdvantage approach to a unified view of Applications and Middleware. Rick Hassman from Pella was one of the customer panelists and during the pre event prep, Rick and I shared backgrounds and found that we had both been plant managers and led ERP deployments prior to leading IT itself. During the panel conversation I explored this with him, discussing the unique perspectives that this provides to CIO’s. He then hit on a point that I wasn’t able to fully appreciate until a week later. First though, some background. The week after the Forum, one of the participants emailed me with the following thoughts: “I am 150% behind this concept……but we are struggling with the concept of web services and the potential use of the Oracle Service Bus technology let alone moving into using the full SOA/BPM/BAM software to extend our JD Edwards application to both integrate and support business processes”. After thinking a bit I responded this way: While I certainly appreciate the degree of change and effort involved, perhaps I could offer the following: One of the underlying principles behind Oracle AppAdvantage is that more often than not, the choice between changing a business process and invasively customizing ERP represents a Hobson's Choice: neither is acceptable. In this case the third option, moving the process out of ERP, is the only acceptable one. Providing this choice typically requires end to end, real time interoperability across applications and/or services. This real time interoperability, to be sustainable over time requires a service oriented architecture. There's just no way around this. SOA adaptation is admittedly tough at the beginning. New skills, new technology and new headaches. But, like any radically new technology, it has a learning curve that drives cost down rather dramatically over time. Tough choices to be sure, but not entirely different than we face with every major technology cycle. Good points of course, but I felt that something was missing. The points were convincing, perhaps even a bit insightful, but they didn’t get at the heart of what Oracle AppAdvantage is focused upon: how the optimization of technology, applications, processes and relationships can change the very way that organizations operate. And then I thought back to the panel discussion with Rick Hassman at Oracle OpenWorld. Rick stressed that Continuous Improvement is a fundamental business strategy at Pella. I remember Continuous Improvement well as I suspect does everyone who was in American manufacturing during the 80’s. Pioneered by W. Edwards Deming in Japan (and still known alternatively as Kaizen), Continuous Improvement sets in place the business culture that we must not become complacent with success and resistant to the ongoing need for change. Many believe that this single handedly drove the renaissance in American manufacturing through the last two decades, which had become complacent during the 70’s and early 80’s. But what exactly does this have to do with SOA? It was Rick’s next point. He drew the connection that moving those business processes that need to continually change over time out of ERP and into edge applications and services enables continuous improvement by empowering people to continually strive for better ways of doing things rather than be being bound by workflows that cannot change. A compelling connection: that SOA, and the overall Oracle AppAdvantage framework of which it is an integral part, can empower people towards continuous improvement in business processes and as a result drive business leadership and business excellence. What better a case for technology innovation?

  • Visualising data a different way with Pivot collections

    - by Rob Farley
    Roger’s been doing a great job extending PivotViewer recently, and you can find the list of LobsterPot pivots at http://pivot.lobsterpot.com.au Many months back, the TED Talk that Gary Flake did about Pivot caught my imagination, and I did some research into it. At the time, most of what we did with Pivot was geared towards what we could do for clients, including making Pivot collections based on students at a school, and using it to browse PDF invoices by their various properties. We had actual commercial work based on Pivot collections back then, and it was all kinds of fun. Later, we made some collections for events that were happening, and even got featured in the TechEd Australia keynote. But I’m getting ahead of myself... let me explain the concept. A Pivot collection is an XML file (with .cxml extension) which lists Items, each linking to an image that’s stored in a Deep Zoom format (this means that it contains tiles like Bing Maps, so that the browser can request only the ones of interest according to the zoom level). This collection can be shown in a Silverlight application that uses the PivotViewer control, or in the Pivot Browser that’s available from getpivot.com. Filtering and sorting the items according to their facets (attributes, such as size, age, category, etc), the PivotViewer rearranges the way that these are shown in a very dynamic way. To quote Gary Flake, this lets us “see patterns which are otherwise hidden”. This browsing mechanism is very suited to a number of different methods, because it’s just that – browsing. It’s not searching, it’s more akin to window-shopping than doing an internet search. When we decided to put something together for the conferences such as TechEd Australia 2010 and the PASS Summit 2010, we did some screen-scraping to provide a different view of data that was already available online. Nick Hodge and Michael Kordahi from Microsoft liked the idea a lot, and after a bit of tweaking, we produced one that Michael used in the TechEd Australia keynote to show the variety of talks on offer. It’s interesting to see a pattern in this data: The Office track has the most sessions, but if the Interactive Sessions and Instructor-Led Labs are removed, it drops down to only the sixth most popular track, with Cloud Computing taking over. This is something which just isn’t obvious when you look an ordinary search tool. You get a much better feel for the data when moving around it like this. The more observant amongst you will have noticed some difference in the collection that Michael is demonstrating in the picture above with the screenshots I’ve shown. That’s because it’s been extended some more. At the SQLBits conference in the UK this year, I had some interesting discussions with the guys from Xpert360, particularly Phil Carter, who I’d met in 2009 at an earlier SQLBits conference. They had got around to producing a Pivot collection based on the SQLBits data, which we had been planning to do but ran out of time. We discussed some of ways that Pivot could be used, including the ways that my old friend Howard Dierking had extended it for the MSDN Magazine. I’m not suggesting I influenced Xpert360 at all, but they certainly inspired us with some of their posts on the matter So with LobsterPot guys David Gardiner and Roger Noble both having dabbled in Pivot collections (and Dave doing some for clients), I set Roger to work on extending it some more. He’s used various events and so on to be able to make an environment that allows us to do quick deployment of new collections, as well as showing the data in a grid view which behaves as if it were simply a third view of the data (the other two being the array of images and the ‘histogram’ view). I see PivotViewer as being a significant step in data visualisation – so much so that I feature it when I deliver talks on Spatial Data Visualisation methods. Any time when there is information that can be conveyed through an image, you have to ask yourself how best to show that image, and whether that image is the focal point. For Spatial data, the image is most often a map, and the map becomes the central mode for navigation. I show Pivot with postcode areas, since I can browse the postcodes based on their data, and many of the images are recognisable (to locals of South Australia). Naturally, the images could link through to the map itself, and so on, but generally people think of Spatial data in terms of navigating a map, which doesn’t always gel with the information you’re trying to extract. Roger’s even looking into ways to hook PivotViewer into the Bing Maps API, in a similar way to the Deep Earth project, displaying different levels of map detail according to how ‘zoomed in’ the images are. Some of the work that Dave did with one of the schools was generating the Deep Zoom tiles “on the fly”, based on images stored in a database, and Roger has produced a collection which uses images from flickr, that lets you move from one search term to another. Pulling the images down from flickr.com isn’t particularly ideal from a performance aspect, and flickr doesn’t store images in a small-enough format to really lend itself to this use, but you might agree that it’s an interesting concept which compares nicely to using Maps. I’m looking forward to future versions of the PivotViewer control, and hope they provide many more events that can be used, and even more hooks into it. Naturally, LobsterPot could help provide your business with a PivotViewer experience, but you can probably do a lot of it yourself too. There’s a thorough guide at getpivot.com, which is how we got into it. For some examples of what we’ve done, have a look at http://pivot.lobsterpot.com.au. I’d like to see PivotViewer really catch on a data visualisation tool.
