  • How to handle people who lie on their resume [closed]

    - by Juliet
    Moderator comment Please note that this is a two year old question that has just been migrated from Stack Overflow. Please take your time to read all the answers and ask yourself "would my answer add anything to this?". I'm conducting technical interviews to fill a few .NET positions. Many of the people I interview really do know .NET pretty well, but I find at least 90% embellish their skillset anywhere between "a little" to "quite drastically". Sometimes they fabricate skills relevant to the position they're applying for, sometimes they don't. Most of the people I interview, even the most egregious liars, are not scam artists. They just want to stand out among the crowd, so they drop a few buzzwords on their resume like "JBoss", "LINQ", "web services", "Django" or whatever just to pad their skillset and stay competitive. (You might wonder if a person that lies about those skills is just bluffing their way through a technical interview. My interviews involve a lot of hands-on coding and problem-solving – people who attempt to bluff will bomb the hands-on coding portion in the first 3 minutes.) These are two open-ended questions, but it would really help me out when I make my recommendations to the hiring managers: Regarding interviewing etiquette, should I attempt to determine whether a person really possesses all of the skills they claim to have? Can I do this without making the candidate feel uncomfortable? Regarding the final decision, should I recommend candidates who are genuinely qualified for the positions they're applying for, even if they've fabricated portions of their skillset?

  • Podcast Show Notes: Old Habits Die Hard in the New SOA World

    - by OTN ArchBeat
    Like the previous series, the latest OTN ArchBeat Podcast program was also recorded in a hotel room just around the corner from Oracle OpenWorld in San Francisco just a few weeks ago. The gathered experts, all members of the OTN architect community, agreed to participate in an informal roundtable discussion of what's happening in Service Oriented Architecture. As you'll hear, the conversation ranged from the maturity of Service Oriented Architecture technology and tools, to the the lingering and typically self-imposed problems that can prevent organizations from realizing the full potential of SOA, to what SOA means in the era of *aaS, mobile computing, and big data. Hajo Normann, Torsten Winterberg, Ronald van Luttikhuizen, and Guido Schmutz (L-R) Hajo Normann, Torsten Winterberg, Danilo Schmeidel, and Lonneke Dikmans (L-R) The Panelists (Listed alphabetically) Lonneke Dikmans, Managing Partner at Vennster, Oracle ACE Director Ronald van Luttikuhuizen, Managing Partner at Vennster, Oracle ACE Director Hajo Normann, SOA & BPM Lead for ASG at Accenture, Oracle ACE Director Danilo Schmiedel, Solution Architect at Opitz Consulting Guido Schmutz, Technology Manager for SOA/BPM and Architecture Board at Trivadis, Oracle ACE Director Torsten Winterberg, Director of Strategy and Innnovation and head of SOA Competence Center at Opitz Consulting, Oracle ACE Director The Conversation Listen to Part 1: SOA technology and tools are mature, says this panel of experts, but why do some organizations still struggle to take full advantage of industrialized SOA? Listen to Part 2 (Nov 6): Human nature and a lack of trust among stakeholders can thwart successful SOA. Can a marketplace approach and social tools improve the situation? Listen to Part 3 (Nov 13): Do SOA stakeholders recognize the problems caused by poor communication among siloed service development teams? Coming Soon SOA and B2B: The authors of Getting Started with Oracle SOA B2B Integration: A Hands-On Tutorial discuss Business to Business capabilities in Oracle SOA Suite 11g.

  • Disable Password Complexity/Expiration etc. Policy on Windows Server 2008

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). One of the things I like to do, for development environments only is to get rid of that excessively bothersome password policies. I like to have my password as something like p@ssword1, so they are easy to remember etc. etc. Obviously never do this in production. However, Windows Server 2008 comes with a password policy that expires my passwords every 90 days, and requires me to pick complex passwords, can’t reuse passwords etc. etc. Well here is how you disable password policy on a Windows Server 2008 machine - Run Group Policy Management (gpmc.msc) Expand to your domain, look for Forest\Domains\yourdomain\default domain policy. Go to the settings tab, right click on the tab, and choose “Edit”. This will open the Group Policy Management Editor, in which - Go to Computer Configuration\Policies\Windows Settings\Security Settings\Account Policies\Password Policy, and change the policy to whatever that suits you. Close everything, and run command prompt as administrator, and issue a “gpupdate /force” command to force the group policy update on the machine. Restart, and you’re done! :) Comment on the article ....

  • Facebook Stories for Retailers

    - by David Dorf
    Getting people to "like" a brand is important because it opens the door to a possible B2C relationship. Once a person likes that brand, the brand can post to their newsfeed with promotions, announcements, and surveys. At least for me, I "hide" the noisy brands and just monitor the ones that keep posts under 4 times a week. I see lots of people, especially with fashion brands, comment on postings at which point the posting is seen by their network. A metric I've heard (but not verified) is that for every person that comments, ten of their friends see the original posting. That's a pretty cheap way to communicate to potential customers in a viral way. Over at mainstreet.com they compiled the a list of the top liked retailers on Facebook as of Feb 1, 2011. They are listed below: 19,414,892 Starbucks 11,302,939 Victoria's Secret 7,925,184 Zara 7,032,398 McDonald's 6,117,222 H&M 5,400,586 Taco Bell 4,665,760 Subway 4,494,849 Lacoste 4,185,570 Hollister 3,973,181 Forever 21 So I guess the public likes their fast-food and fashion. To take this to the next level, Facebook is now displaying Sponsored Stories, which I saw for the first time on my page this weekend. I found this picture at the Wall Blog that depicits Sponsored Stories very well. Over on the right-hand column of a person's page, where they see advertisements and such, Facebook will post stories involving their network of friends and their interaction with sponsored brands. Now their "likes" can suddenly become your ads. "Jessica and Philip like Starbucks. What are you waiting for?" This is another great way to take messages viral by accessing social graphs. As usual there will be a certain level of outcry from privacy advocates, but given the other more iniquitous issues, I believe this will fall by the wayside. Retailers should consider using Sponsored Stories to increase their Likes, and thus increase their voice in the social world.

  • Netbook performs hard shutdown without warning on low battery power

    - by Steve Kroon
    My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification. Some additional information on the battery: kroon@minia:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0A:00/power_supply/BAT0 vendor: ASUS model: 1005P power supply: yes updated: Fri Aug 17 07:31:23 2012 (9 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 33.966 Wh energy-empty: 0 Wh energy-full: 34.9272 Wh energy-full-design: 47.52 Wh energy-rate: 3.7692 W voltage: 12.61 V time to full: 15.3 minutes percentage: 97.248% capacity: 73.5% technology: lithium-ion History (charge): 1345181483 97.248 charging 1345181453 97.155 charging 1345181423 97.062 charging 1345181393 96.970 charging History (rate): 1345181483 3.769 charging 1345181453 3.899 charging 1345181423 4.061 charging 1345181393 4.201 charging kroon@minia:~$ cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charging present rate: 332 mA remaining capacity: 3149 mAh present voltage: 12612 mV kroon@minia:~$ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 4400 mAh last full capacity: 3209 mAh battery technology: rechargeable design voltage: 10800 mV design capacity warning: 10 mAh design capacity low: 5 mAh cycle count: 0 capacity granularity 1: 44 mAh capacity granularity 2: 44 mAh model number: 1005P serial number: battery type: LION OEM info: ASUS

  • SQLAuthority News – Download Whitepaper – Choosing a Tabular or Multidimensional Modeling Experience in SQL Server 2012 Analysis Services

    - by pinaldave
    Data modeling is the most important task for any BI professional. Matter of the fact, the biggest challenge is to organizing disparate data into an analytic model that effectively and efficiently supports the reporting and analysis. SQL Server 2012 introduces BI Semantic Model (BISM), a single model that can support a broad range of reporting and analysis while blending two Analysis Services modeling experiences behind the scenes. Multidimensional modeling – enables BI professionals to create sophisticated multidimensional cubes using traditional online analytical processing (OLAP). Tabular modeling – provides self-service data modeling capabilities to business and data analysts. As data modeling is evolving and business needs are growing new technologies and tools are emerging to help end users to make the necessary adjustment to the reporting and analysis needs. This white paper is will provide practical guidance to help you decide which SQL Server 2012 Analysis Services modeling experience – tabular or multidimensional. Do let me know what do is your opinion as a comment. In simple word – I would like to know when will you use Tabular modeling and when Multidimensional modeling?

  • Would this be viewed poorly amongst the programming community?

    - by Eric P
    So one of my responsibilities at work is to build an internal tool that helps the workers enter in all their information. It's an enterprise application that is similar to a Windows forms database tool. So it's not much different than like developing a Word + Excel combo application, but the average person in this workgroup is a 20-40 year old woman or a random chatty male type. Plus I know all of these people are heavily involved with Facebook on a daily basis. How bad would it be if I styled my new interface to be similar to what Facebook does. People could get award points and stuff when they fill out different types of forms and basically compete against each other like it was a game. When people had completed one, it would be posted on their wall and everyone could comment/like stuff just like in Facebook. And it would be like they are doing peer reviewing for fun. The rewards would be outstanding I would imagine. These people are so into Facebook and Facebook games that productivity would rise due to them trying to compete and earn points and achievements. Would this be taking advantage of the people by 'tricking them into working harder by giving them a game' or would it be viewed as something that would improve happiness at work?

  • Strange if-else branching behavior in a fragment shader

    - by Winged
    In my fragment shader I have passed an uniform int uLightType variable, which indicates what type of light is in usage right now. The problem is that if-else branching does not work correctly - the fragment shader performs instructions in every if statement block. if (uLightType == 1) { // Spotlight light type vec3 depthTextureCoord = vDepthPosition.xyz / vDepthPosition.w; shadowDepth = unpack(texture2D(uDepthMapSampler, depthTextureCoord.xy)); } else if (uLightType == 2) { // Omni-directional light type shadowDepth = unpack(textureCube(uDepthCubemapSampler, -lightVec)); } In the case when uLightType equals 1, unless I comment out the content of the second if block, it assigns an another value to shadowDepth. Also while uLightType equals 1, when I remove the second 'if' block and change == to != like in the sample code below, nothing happens (which means that uLightType really equals 1). if (uLightType != 1) { // Spotlight light type vec3 depthTextureCoord = vDepthPosition.xyz / vDepthPosition.w; shadowDepth = unpack(texture2D(uDepthMapSampler, depthTextureCoord.xy)); } Also, when I manually create an int variable (which is not an uniform) like this: var lightType = 1; and replace uLightType with it in the if-else branch, everything works fine, so I guess it have something to do with the fact that uLightType is the uniform.

  • What is the way to submit a patch to fix all the damage that LP: #600941 causes?

    - by nutznboltz
    What is the best way to submit a patch to fix all the damage that LP: #600941 causes? I ask because LP: #600941 was put into every version of Ubuntu still supported at this time. Should I pick a particular version and run ubuntu-bug on it? Should that version be the LTS or Oneiric or Precise (how can I get Precise if I need it?) The story is that after it was pushed out all of our systems started experiencing Nagios nrpe restart failures. Commands like /etc/init.d/nagios-nrpe-server restart would cause nrpe to stop but not restart. I tracked this down to the way that the /etc/init.d/nagios-nrpe-server script is calling start-stop-daemon. The issue is that the "stop" stanza in the /etc/init.d/nagios-nrpe-server script first calls start-stop-daemon which sends SIGTERM to nrpe and then waits only for one second. If nrpe has not exited by that time the pid file will still exist and the /etc/init.d/nagios-nrpe-server script will remove it. Worse if /etc/init.d/nagios-nrpe-server restart is used not only will the pid file be removed, the attempt to restart nrpe will fail provided that the nrpe daemon is still tardy in shutting down. The attempt to start under those circumstances will fail because nrpe will still be bound to a socket and the second attempt at binding will cause the nrpe startup to abort. They should have wondered why there was a comment about "sometimes the pid file does not get removed". They should have tested on systems that have a heavy load and therefore slow nrpe response times. The fix is to add --retry 10 or such to the invocation of start-stop-daemon ... --stop ... Thanks

  • Should my program "be lenient" in what it accepts and "discard faulty input silently"?

    - by romkyns
    I was under the impression that by now everyone agrees this maxim was a mistake. But I recently saw this answer which has a "be lenient" comment upvoted 137 times (as of today). In my opinion, the leniency in what browsers accept was the direct cause of the utter mess that HTML and some other web standards were a few years ago, and have only recently begun to properly crystallize out of that mess. The way I see it, being lenient in what you accept will lead to this. The second part of the maxim is "discard faulty input silently, without returning an error message unless this is required by the specification", and this feels borderline offensive. Any programmer who has banged their head on the wall when something fails silently will know what I mean. So, am I completely wrong about this? Should my program be lenient in what it accepts and swallow errors silently? Or am I mis-interpreting what this is supposed to mean? Taken to the extreme, if Excel followed this maxim and I gave it an exe file to open, it would just show a blank spreadsheet without even mentioning that anything went wrong. Is this really a good principle to follow?

  • FreeType2 Crash on FT_Init_FreeType

    - by JoeyDewd
    I'm currently trying to learn how to use the FreeType2 library for drawing fonts with OpenGL. However, when I start the program it immediately crashes with the following error: "(Can't correctly start the application (0xc000007b))" Commenting the FT_Init_FreeType removes the error and my game starts just fine. I'm wondering if it's my code or has something to do with loading the dll file. My code: #include "SpaceGame.h" #include <ft2build.h> #include FT_FREETYPE_H //Freetype test FT_Library library; Game::Game(int Width, int Height) { //Freetype FT_Error error = FT_Init_FreeType(&library); if(error) { cout << "Error occured during FT initialisation" << endl; } And my current use of the FreeType2 files. Inside my bin folder (where debug .exe is located) is: freetype6.dll, libfreetype.dll.a, libfreetype-6.dll. In Code::Blocks, I've linked to the lib and include folder of the FreeType 2.3.5.1 version. And included a compiler flag: -lfreetype My program starts perfectly fine if I comment out the FT_Init function which means the includes, and library files should be fine. I can't find a solution to my problem and google isn't helping me so any help would be greatly appreciated.

  • When and why you should use void (instead of i.e. bool/int)

    - by Jonas
    I occasionally run into methods where a developer chose to return something which isn't critical to the function. I mean, when looking at the code, it apparently works just as nice as a void and after a moment of thought, I ask "Why?" Does this sound familiar? Sometimes I would agree that most often it is better to return something like a bool or int, rather then just do a void. I'm not sure though, in the big picture, about the pros and cons. Depending on situation, returning an int can make the caller aware of the amount of rows or objects affected by the method (e.g., 5 records saved to MSSQL). If a method like "InsertSomething" returns a boolean, I can have the method designed to return true if success, else false. The caller can choose to act or not on that information. On the other hand, May it lead to a less clear purpose of a method call? Bad coding often forces me to double-check the method content. If it returns something, it tells you that the method is of a type you have to do something with the returned result. Another issue would be, if the method implementation is unknown to you, what did the developer decide to return that isn't function critical? Of course you can comment it. The return value has to be processed, when the processing could be ended at the closing bracket of method. What happens under the hood? Did the called method get false because of a thrown error? Or did it return false due to the evaluated result? What are your experiences with this? How would you act on this?

  • SQL SERVER – Follow up – Usage of $rowguid and $IDENTITY

    - by pinaldave
    The most common question I often receive is why do I blog? The answer is even simpler – I blog because I get an extremely constructive comment and conversation from people like DHall and Kumar Harsh. Earlier this week, I shared a conversation between Madhivanan and myself regarding how to find out if a table uses ROWGUID or not? I encourage all of you to read the conversation here: SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables. In simple words the conversation between Madhivanan and myself brought out a simple query which returns the values of the UNIQUEIDENTIFIER  without knowing the name of the column. David Hall wrote few excellent comments as a follow up and every SQL Enthusiast must read them first, second and third. David is always with positive energy, he first of all shows the limitation of my solution here and here which he follows up with his own solution here. As he said his solution is also not perfect but it indeed leaves learning bites for all of us – worth reading if you are interested in unorthodox solutions. Kumar Harsh suggested that one can also find Identity Column used in the table very similar way using $IDENTITY. Here is how one can do the same. DECLARE @t TABLE ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, IDENTITYCL INT IDENTITY(1,1), data VARCHAR(60) ) INSERT INTO @t (data) SELECT 'test' INSERT INTO @t (data) SELECT 'test1' SELECT $rowguid,$IDENTITY FROM @t There are alternate ways also to find an identity column in the database as well. Following query will give a list of all column names with their corresponding tablename. SELECT SCHEMA_NAME(so.schema_id) SchemaName, so.name TableName, sc.name ColumnName FROM sys.objects so INNER JOIN sys.columns sc ON so.OBJECT_ID = sc.OBJECT_ID AND sc.is_identity = 1 Let me know if you use any alternate method related to identity, I would like to know what you do and how you do when you have to deal with Identity Column.

  • Great Blog Comments

    - by Paul Sorensen
    Just a quick note to let you know that in the interest of keeping the most useful content available here on the Oracle Certification Blog, we do moderate the comments. We welcome (and encourage dialog, questions, comments, etc) here on the topics at hand. We'll never 'censor' out a comment just because we don't like it - in fact, this is how we often learn ways in which we can do better. But of course we will filter out the typical list like anyone else: crude/offensive remarks, foul language, reference to illegal activity, etc. We will also often redirect any customer-service type inquiries to [email protected] where they can best be handled.Also, if you have a question of a general nature, please research it on the Oracle Certification website first. We often won't respond to questions asking such as "tell me how to get 11g ocp", as we've already made sure that you have that kind of information available. Now if we've inadvertently 'hidden' something on our site (gulp), then fair enough - please let us know that you're having a hard time finding it and we'll be sure to try and "unbury it" ;-)Additionally, you may have more of an 'opinion' type question, such as "should I do 'x' certification or 'y' certification." For these, we highly recommend checking on the Oracle Technology Network (OTN) Certification Forum, where you can engage in peer-to-peer discussions, share techniques, advice and best practices with others in the field.In the meantime, please continue to share your thoughts, ideas, opinions, tech tips etc - we look forward to seeing them and passing them wherever we can!QUICK LINKS:Oracle Certification WebsiteEmail - Customer ServiceOracle Technology Network (OTN) Certification Forum

  • XNA Seeing through heightmap problem

I've managed to draw a simple terrain, but I'm getting a weird bug where I can see through the terrain. This bug happens when I'm looking through a hill from the map. Here is a picture of what happens: I was wondering if this is a common mistake for starters and if any of you ever experienced the same problem and could tell me what I'm doing wrong. If it's not such an obvious problem, here is my Draw method: public override void Draw() { Parent.Engine.SpriteBatch.Begin(SpriteBlendMode.None, SpriteSortMode.Immediate, SaveStateMode.SaveState); Camera3D cam = (Camera3D)Parent.Engine.Services.GetService(typeof(Camera3D)); if (cam == null) throw new Exception("Camera3D couldn't be found. Drawing a 3D terrain requires a 3D camera."); float triangleCount = indices.Length / 3f; basicEffect.Begin(); basicEffect.World = worldMatrix; basicEffect.View = cam.ViewMatrix; basicEffect.Projection = cam.ProjectionMatrix; basicEffect.VertexColorEnabled = true; Parent.Engine.GraphicsDevice.VertexDeclaration = new VertexDeclaration( Parent.Engine.GraphicsDevice, VertexPositionColor.VertexElements); foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Begin(); Parent.Engine.GraphicsDevice.Vertices[0].SetSource(vertexBuffer, 0, VertexPositionColor.SizeInBytes); Parent.Engine.GraphicsDevice.Indices = indexBuffer; Parent.Engine.GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, vertices.Length, 0, (int)triangleCount); pass.End(); } basicEffect.End(); Parent.Engine.SpriteBatch.End(); } Parent is just a property holding the screen that the component belongs to. Engine is a property of that parent screen holding the engine that it belongs to. If I should post more code(like the initialization code), then just leave a comment and I will.

  • Term for unit testing that separates test logic from test result data

    - by mario
    So I'm not doing any unit testing. But I've had an idea to make it more appropriate for my field of use. Yet it's not clear if something like this exists, and if, how it would possibly be called. Ordinary unit tests combine the test logic and the expected outcome. In essence the testing framework only checks for booleans (did this match, did the expected result result). To generalize, the test code itself references the audited functions, and also explicites the result values like so: unit::assert( test_me() == 17 ) What I'm looking for is a separation of concerns. The test itself should only contain the tested logic. The outcome and result data should be handled by the unit testing or assertion framework. As example: unit::probe( test_me() ) Here the probe actually doubles as collector in the first run, and afterwards as verification method. The expected 17 is not mentioned in the test code, but stored or managed elsewhere. How is this scheme called? Or how would you call it? I hope I can find some actual implementations with the proper terminology. Obviously such a pattern is unfit for TDD. It's strictly for regression testing. Also obviously, it cannot be used for all cases. Only the simpler test subjects can be analyzed that way, for anything else the ordinary unit test setup and assertion steps are required. And yes, this could be manually accomplished by crafting a ResultWhateverObject, but that would still require hardwiring that to the test logic. Also keep in mind that I'm inquiring for use with scripting languages, and not about Java. I'm aware that the xUnit pattern originates there, and why it's hence as elaborate as it is. Btw, I've discovered one test execution framework which allows for shortening simple test notations to: test_me(); // 17 While thus the result data is no longer coded in (it's a comment), that's still not a complete separation and of course would work only for scalar results.

  • Different Flavors of Leases Back On

    - by Theresa Hickman
    Given the continued interest regarding the proposed changes to Lease Accounting, I decided to write another entry on this controversial topic with colorful commentary from our resident accounting expert, Seamus Moran. Background (A History Lesson) Back in 1976, the FASB issued FAS 13, “Accounting for Leases” that permitted leases to be either an operating lease or capital (finance) lease. In substance, operating leases are a form of off-balance sheet financing. According to Seamus, operating leases date back to the launch of the Boeing 707 in the 1950s.  Because the aircraft was so much more expensive than previous aircrafts, the industry came up with the operating lease concept to accommodate these jet liners that dominated air transport.  How it worked was the bank would buy the plane and lease it to the airline.  Because the bank never controlled or flew the plane, they never placed the asset on their balance sheet, and because the airline never owned the plane, they didn’t place it on their balance sheet either. They simply treated the monthly lease payments as rental expenses on the P&L.   August 2010 Original Lease Accounting Changes In August 2010, FASB and IASB decided to overhaul lease accounting as part of their joint commitment “to insure that investors and other users of financial statements are provided useful, transparent, and complete information about leasing transactions in the financial statements.”  Some say that the current lease accounting standards are broken because it keeps assets off the balance sheet, hidden from investors’ view. The original proposal abolished operating leases and only permitted capital leases where all leases would be recorded on the balance sheet as assets and liabilities. The asset side would reflect the right to use the asset for the leased term, and the liability side would reflect the obligation to make lease payments.   Why Companies Were Freaking Out According to the SEC, the financial impact of the aforementioned lease changes was estimated to add more than $1.3 trillion of operating lease obligations to corporate balance sheets. Many companies in various industries, especially retail, are concerned because the changes are significant and will impact existing leases with no grandfather clause for existing operating leases. Of course, the banks and airlines I mentioned earlier really hate this because neither wants to report the airplane (now costing around $60 M) as an asset. Regular companies were concerned that they would have to report routine short term leases of real estate or equipment as fixed assets, even though they were really just longer term rentals.  One company we spoke to leased roadside billboards, and really did not consider them to be fixed assets in any way. Obviously, these changes would have had a profound and lasting effect on a company’s financial and real estate strategies and significantly impact its financial statements.  Financial statements would show higher depreciation and interest expense with significantly higher total assets and debt. In terms of financial metrics, they’re negatively impacted. It would raise a company’s debt-to-capital ratio to reflect the higher debt compared to equity, it would negatively impact their return-on-assets because now companies will appear more asset intensive, and it will decrease EPS, lowering shareholder ROI. Feb. 2011 Recent Update The comment period on leases closed in December 2010. The FASB and the IASB have met several times since then and published their initial responses to the input they received from the various interested parties.  They are “redeliberating” the principles involved in Lease Accounting.  Some of the issues they are looking at include: The core definition of a lease.  This will articulate principles on what is a lease and what is “not-a-lease.” One theory or supposition is that they might define a lease as the transfer of certain but not all major ownership attributes for a certain period of time.  So a year’s lease of an aircraft might be a “lease,” but a year’s lease of half a floor in an office building would be “not-a-lease.”  The ownership attributes transferred from the core owner to the user are different; the airline must maintain, paint, and do whatever it needs to do on the aircraft. However, the office renter will have strictly limited rights in respect to the rented space. The differences between a lease contract and service contract.  Even if they call them “leases” for the purpose of commercial law, a service contract might not be accounted for as a lease. The accounting to be done by the lessee.  They would define when the bank or landlord would retain the asset on their balance sheet, and perhaps by implication, when the lessor would not need to include the asset on theirs.  So if the finance house keeps the airplane or office on their balance sheet, the tenant doesn’t need to.  I’m not sure that I can draw the opposite conclusion where the finance house doesn’t report but the tenant must. The difference, if any, between a financing lease and other leases, and the implications to the accounting. The present value calculation when renewable terms exist. They have reduced the circumstances in which one must look at the renewable terms of a lease in calculating the present value.  In most circumstances, you will use the lease term rather than the potential renewable term. Their latest discussion this past week with the contents of the discussion was not available at the time of me writing this entry.  For more details, the results of the discussions are posted on both the FASB and the IASB websites. Implied Software Changes Whatever the final rules turn out to be, all ERP systems, such as Oracle E-Business Suite, PeopleSoft Enterprise, JD Edwards, and Oracle Hyperion will need to change their software to accommodate the new rules. The following lists some changes that might have to be made to accounting software depending on what the final standards will be in June 2011: Lease tracking may require modifications with tracking of additional lease details that might require a centralized repository to maintain Accounting may need to be modified as there are many changes to how capital leases and the new “other than finance” leases are accounted for both on the lessee and lessor side.  For example, valuation, amortization, and disclosure will be considerably different requiring different types of data to be captured. Companies may need to modify their chart of accounts depending on how they want to track leases, which could then impact financial reporting and consolidation Business processes may require changes which could then impact internal controls Software applications may need to perform more advanced computations on leases Reports and KPIs may need to reflect new operating metrics Hold Onto Your Seats           Before you redo all your lease agreements and call your software vendors asking when the changes to the software will be made, remember that the rules are not finalized yet, and from appearances, will not reflect the proposals in the exposure draft.  Not only are there objections to putting the operating lease assets on anyone’s balance sheet, there are lots of objections to subjectivity and the data required for the valuation.  According to Seamus, there is huge opposition from New York bankers, the airlines, the EU, the Communist Party of China (since it impacts their exporting business), and Republicans (hearing complaints from small and large businesses). Even if everyone can agree on the proposed changes, 2013 might be the earliest that companies would need to change how they report leases. The Boards will finish their deliberations in April, May or June 2011.  As we’ve seen with other Exposure Drafts, if the changes are minor and the principles met the General Acceptance consensus criteria, the Standard could be finalized at that time.  However, if substantial changes are made, a fresh exposure draft, comment period, and review period might be involved, too. Seamus added an interesting perspective. Even if the proposed changes do pass, don’t you think our customers, such as Boeing, GE Capital, United Airlines, etc. will be clever enough to come up with a new kind of financing arrangement that complies with the new accounting? How about the large retail customers, such as Best Buy and Macerich? Don’t you think they might simply cut deals around retail locations with new contracts that prevent their leases from being capital leases? Instead of blindly adapting the software to meet the principles outlined in the final standard, our software needs to accommodate how businesses will respond to the new rules. We cannot know our customers’ responses until the rules are finalized. Oracle is aware of the potential changes and is staying abreast of the developments through our domain expertise staff, our relationship with customers, our market awareness, and, of course, our relationships with the Big 4. This is part of our normal process with respect to worldwide regulatory compliance. Oracle products have been IFRS and GAAP compliant for years and we will continue to maintain those standards going forward.

  • .NET development on Macs

    - by Jeff
    I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

  • What Should You Look for In a CRM Demo?

    - by charles.knapp
    I have helped firms evaluate software demos and delivered demos in diverse industries such as manufacturing, healthcare, life sciences, and travel (to name just a few). Here are a few suggestions. First, which vendor has the best fit for your industry? Make sure that the vendor demo staff tell you clearly throughout the demo (not just in a passing comment), what portion of each business process and screen is standard, what has been configured, what has been custom coded, and what has been provided by a partner. If you don't keep asking, what you buy may be less useful than what you saw. This will lead to added (and unbudgeted) costs and time. Second, what are the roles of the primary users? What are their top-most needs, such as exception-oriented dashboards or rapid data entry? Can you get a demo for each key role, showing how the software fits a typical workday? Have the vendor repeatedly tell you what is standard, configured, custom coded, or provided by a partner. Third, how well does the demo balance ease of use with completeness of business processes? One common approach is to hide needed fields or steps that are of low visual value. Another approach is to focus heavily on a visually appealing capability, while downplaying the fit with your key business processes. Result: despite their business acumen, demo attendees may not focus adequately on gaps in business fit So, look for complete disclosure and complete CRM.

  • How to visualize timer functionality in sequence diagram?

    - by truthseeker
    I am developing software for communication with external device through serial port. To better understand the new functionality I am trying to display it in sequence diagram. Flow of events is as follows. I send to the device command to reset it. This is asynchronous operation so there is some delay between request and response (typically 100 ms). There can be case when the answer never comes (for example device is not connected to the specified port or is currently turned off). For this purpose I create a timer with period twice the maximum answer time. In my case it is 2 * 125 ms = 250 ms. If the answer comes in predefined time interval, I destroy already running timer. If the answer doesnt come in predefined interval, timer initiates some action. After this action we can destroy it. How to effectively model this situation in sequence diagram? Addendum 1: Based on advices made by scarfridge i drew following UML diagram. Comment by Ozair is also helpful for simplifying the diagram even more.
