• SQL SERVER – BI Quiz Hint – Performance Tuning Cubes – Hints

  - by pinaldave

  I earlier wrote about SQL BI Quiz over here and here. The details of the quiz is here: Working with huge data is very common when it is about Data Warehousing. It is necessary to create Cubes on the data to make it meaningful and consumable. There are cases when retrieving the data from cube takes lots of the time. Let us assume that your cube is returning you data very quickly. Suddenly on one day it is returning the data very slowly. What are the three things will you to diagnose this. After diagnose what you will do to resolve performance issue. Participate in my question over here I required BI Expert Jason Thomas to help with few hints to blog readers. He is one of the leading SSAS expert and writes a complicated subject in simple words. If queries were executing properly before but now take a long time to return the data, it means that there has been a change in the environment in which it is running. Some possible changes are listed below:-  1) Data factors:- Compare the data size then and now. Increase in data can result in different execution times. Poorly written queries as well as poor design will not start showing issues till the data grows. How to find it out? (Ans : SQL Server profiler and Perfmon Counters can be used for identifying the issues and performance  tuning the MDX queries)  2) Internal Factors:- Is some slow MDX query / multiple mdx queries running at the same time, which was not running when you had tested it before? Is there any locking happening due to proactive caching or processing operations? Are the measure group caches being cleared by processing operations? (Ans : Again, profiler and perfmon counters will help in finding it out. Load testing can be done using AS Performance Workbench (http://asperfwb.codeplex.com/) by running multiple queries at once)  3) External factors:- Is some other application competing for the same resources?  HINT : Read “Identifying and Resolving MDX Query Performance Bottlenecks in SQL Server 2005 Analysis Services” (http://sqlcat.com/whitepapers/archive/2007/12/16/identifying-and-resolving-mdx-query-performance-bottlenecks-in-sql-server-2005-analysis-services.aspx) Well, these are great tips. Now win big prizes by participate in my question over here.

• Returning null vs Throwing exceptions

  - by Svish

  Is in a bit of disagreement with a more experienced developer on this issue, and was wondering what you guys here think about this. Environment is Java, EJB 3, services, etc. The code I wrote calls a service to get things and to create things. Problem was that I got null pointer exceptions in places that didn't make sense. For example when I asked the service to create an object, I got null back. And when I tried to look up an object with an id I knew existed, I still got null back. Was like it was ignoring me. Spent some time trying to figure out what was wrong in my code (since I'm less experienced I usually assume I have messed up). Turns out the reason was security. If the user principal using my service didn't have the right permissions to use the service I called from my service, then that service simply returned null. The services that are here already are usually not documented either, so this is just something you have to know... somehow... So here is the thing: I mean that this is rather confusing as a developer interacting with this service. To me it would make much more sense if that service thew an exception which would tell me that hey, you don't have the proper permissions to get info about this thing or to create this new thing. I would then immediately know why my service wasn't working as expected. However, he argued that asking is not wrong. Exceptions should only be thrown when there is an error and asking for a thing is not an error. Even if you don't have permission to "see" that the thing you asked for. The things are often looked up in a GUI by users and for those users not having the right permissions, these things simply "do not exist". So, in short: Asking is not wrong, hence no exception. Get methods return null because to those users those things "doesn't exist". Create methods return null because nothing was created, since the user wasn't allowed to create anything. So, what do you guys think? Is this normal and/or good practice? I prefer exceptions as I prefer throwing and catching exceptions because I find it much easier to know what's going on. So I would for example also prefer to throw a NotFoundException if you asked for an id which didn't exist, rather than returning null. Anyways, just curious to what others think about this as I'm not the most experienced developer yet.

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubiquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with mixed languages anyway. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options? UPDATE Today, about year later, having dealt with this issue on a daily basis, I have to say that option 3 has worked out pretty well for me. It wasn't as tedious as I initially feared and translating in real time while talking to the client wasn't a problem either. I also found the following advantages to be true, based on my experience. Translating the UL makes you pay more attention to defining the UL and even the domain itself, especially when you don't know how to translate a term and you have to start looking through dictionaries etc. This has even caused me to reconsider domain modeling decisions a few times. It helps you make your knowledge of the English language more profound. Obviously, your code is much more pleasant to look at instead of being a mind boggling obscenity.

• Star rating not showing in rich snippets

  - by Danny R

  We've recently been doing a lot of work on our site's SEO (www.betterthanreviews.com). We recently did a push to update the rich snippets breadcrumb, meta description, and star rating. After giving Google some time to index the site, it has updated the breadcrumbs and meta descriptions for our review pages, but the stars are still not showing. This is currently how it appears on a Google search (link to the actual page: http://www.betterthanreviews.com/home-security/livewatch): This is what the Rich Snippets is supposed to look like, and how it appears in Google's testing tool: More context: As seen in our html, we are using schema.org language. We initially were using schema.org/Corporation for the site, but we now have the page labeled as schema.org/HomeAndConstructionBusiness because Google will not show star ratings for the Corporation language. However, in our Webmaster Tools, the Structured Data is still showing the Corporation language, which could be a potential issue. Here is a look at some of the coding that we used. But it can be looked at closer by inspecting the element: <div class="aggregate-rating" itemprop="aggregateRating" itemscope="" itemtype="http://schema.org/AggregateRating"> <div class="review row_fluid" itemprop="review" itemscope="" itemtype="http://schema.org/Review"> <div class="row_fluid rating" itemprop="reviewRating" itemscope="" itemtype="http://schema.org/Rating"> <meta content="4.5" itemprop="ratingValue" title="4.5 out of 5 stars" class="star-rating-readonly"> <meta content="2013-12-05" itemprop="datePublished"> <p class="review-headline" itemprop="headline">Way better than my previous system</p> <div> <p class="reviewer" itemprop="author">Scott H. </p> <span class="bullet">•</span> <p class="created_at">2 months ago</p> <p class="content" itemprop="description">I love it!

• SQL SERVER – Script to Update a Specific Column in Entire Database

  - by Pinal Dave

  Last week, I have received a very interesting question and I find in email and I really liked the question as I had to play around with SQL Script for a while to come up with the answer he was looking for. Please read the question and I believe that all of us face this kind of situation. “Pinal, In our database we have recently introduced ModifiedDate column in all of the tables. Now onwards any update happens in the row, we are updating current date and time to that field. Now here is the issue, when we added that field we did not update it with a default value because we were not sure when we will go live with the system so we let it be NULL. Now modification to the application went live yesterday and we are now updating this field. Here is where I need your help. We need to update all the tables in our database where we have column created ModifiedDate and now want to update with current datetime. As our system is already live since yesterday there are several thousands of the rows which are already updated with real world value so we do not want to update those values. Essentially, in our entire database where ever there is a ModifiedDate column and if it is NULL we want to update that with current date time?  Do you have a script for it?” Honestly I did not have such a script. This is very specific required but I was able to come up with two different methods how he can use this method. Method 1 : Using INFORMATION_SCHEMA SELECT 'UPDATE ' + T.TABLE_SCHEMA + '.' + T.TABLE_NAME + ' SET ModifiedDate = GETDATE() WHERE ModifiedDate IS NULL;' FROM INFORMATION_SCHEMA.TABLES T INNER JOIN INFORMATION_SCHEMA.COLUMNS C ON T.TABLE_NAME = C.TABLE_NAME AND c.COLUMN_NAME ='ModifiedDate' WHERE T.TABLE_TYPE = 'BASE TABLE' ORDER BY T.TABLE_SCHEMA, T.TABLE_NAME; Method 2: Using DMV SELECT 'UPDATE ' + SCHEMA_NAME(t.schema_id) + '.' + t.name + ' SET ModifiedDate = GETDATE() WHERE ModifiedDate IS NULL;' FROM sys.tables AS t INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID WHERE c.name ='ModifiedDate' ORDER BY SCHEMA_NAME(t.schema_id), t.name; Above scripts will create an UPDATE script which will do the task which is asked. We can pretty much the update script to any other SELECT statement and retrieve any other data as well.

• Installing Ubuntu 12.04 on NUC intel i3 DC3217IYE

  - by Kieron

  System: NUC i3, 2 hdmi ports, ethernet, no wireless. UEFI boot 2x2gb ram 30gb mSATA internal drive Ubuntu 64bit 12.04.03 Hello i am having much trouble loading an OS on my NUC. I started out attempting another OS with various loaders (beast/hack) without much success,(various panics on boot or endless reboot loops, or graphics failures) after many tries i decided to attempt Ubuntu. Many years ago i loaded Ubuntu on an e-machine without an issue so i figured it would go smoothly, nothing could be further from the truth. The Live USB stick loads, but when i am installing the OS it always fails to load grub 2. Obviously it wont boot from SSD without grub2. I searched and found that Boot-repair should fix it...so i created a live usb with boot repair...it refuses to repair the grub because the install never finished and the needed partions are not fully created and flagged. It also demands an internet connection which i am unable to provide. I then ran gparted in an attempt to create the needed partitions manually, then re-ran boot repair turning off the "check internet" option. and disabling the re-install grub hoping it would create the missing directories and or fix the flags. it appeared to run successfully but upon return to the Ubuntu live USB it still fails at the grub2 install. also gparted doesnt have the same choices that Ubuntu install has when creating partitions, causing it to not recognize that i already had a root, or an EFI directory or it sometimes couldnt tell what the format of the partition was...all very annoying the reason i cant connect to internet (and cant upload the error logs) is the nuc only has Ethernet and the location i have to set up is too far away from modem. i can not move the monitor closer to modem as it is a 50inch LCD. I just want to do a basic install with one user acct and remote desktop (vnc) turned on so i can move the NUC to the modem connect via ethernet and then finish setting it up via Remote desktop/VNC chicken from my mac. While i await any assistance you maybe able to provide i am going to attempt to switch to the 32bit version and legacy boot to see if that can load grub. thnx again to anyone that can come up with a possible solution. i would love to hit "erase and install ubuntu" if anyone can figure out what is stopping that simple answer from working. Also disks (CD/DVD) are not an option as neither my Mac mini or my NUC have optical drives, and i have no desire to buy one for one task

• Create USB installer from the command line?

  - by j-g-faustus

  I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. unetbootin scripting: Requires X server (graphics support) to run, even when fully scripted. (The command sudo unetbootin lang=en method=diskimage isofile=~/ubuntu-10.10-server-amd64.iso installtype=USB targetdrive=/dev/sdg1 autoinstall=yes gives an error message unetbootin: cannot connect to X server.) Update Also tried GRUB fiddling: Merging information from pendrivelinux.com a related question on the Linux Stackexchange and a grub configuration example I was able to get halfway there - it booted from USB, displayed the grub menu and started the installation, but installation did not complete. For reference, this is the closest I got: sudo su # mount USB pen mount /dev/sd[X]1 /media/usb # install GRUB grub-install --force --no-floppy --root-directory=/media/usb /dev/sd[X] # copy ISO image to USB cp ~/ubuntu-10.10-server-amd64.iso /media/usb # mount ISO image, copy existing grub.cfg mount ~/ubuntu-10.10-server-amd64.iso /media/iso/ -o loop cp /media/iso/boot/grub/grub.cfg /media/usb/boot/grub/ I then edited /media/usb/boot/grub.cfg to add an .iso loopback, example grub entry: menuentry "Install Ubuntu Server" { set gfxpayload=keep loopback loop /ubuntu-10.10-server-amd64.iso linux (loop)/install/vmlinuz file=(loop)/preseed/ubuntu-server.seed iso-scan/filename=/ubuntu-10.10-server-amd64.iso quiet -- initrd (loop)/install/initrd.gz } When booting from USB, this would give me the Grub boot menu and start the installer, but the installer gave up after a couple of screens complaining that it couldn't find the CD-ROM drive. (Naturally, as the box I'm installing on doesn't have an optical drive.) I resolved this particular issue by giving up and doing the "create USB drive" routine using the Ubuntu Live desktop CD (on a computer that does have an optical drive), then the USB install works. But I expect that there is some way to do this from the command line of an Ubuntu system without X server and without an optical drive, so the question still stands. Does anyone know how?

• Debugging .NET code called from X++ code in AX 2012

  - by ssmantha

  A very intriguing issue came to me to debug .Net code called from X++ code in AX 2012. This was indeed a challenge to be nailed down. Luckily the tools and some concepts helped me to achieve this task. Here it goes... We need to do a seamless debugging from AX debugger to Visual Studio back and forth. To enable this we need to first see if the dll to be debug is present in GAC then we might need to uninstall it from it due to the order of preference .NET loads the assemblies. The assemblies are first loaded from GAC and then the runtime checks for Public and Private Assemblies. Since the assembly in GAC is always compiled with runtime optimizations it is difficult to debug. We need to unhook this assembly from GAC and then move further relying on >NET assembly loading patterns. Step 1: Remove the target assembly to debug from GAC. Before that stop all the AOS servers and close all the instances of programs which rely on AOT e.g. all clients and even visual studio now. Step 2: Build your sample code which is present in AOT in debug mode and get the dll file along with PDB files. Step 3: Place these files in the Server\..\Bin and Client\bin directories of AX installation. Step 4: Configure Visual Studio: Step 4.1: Configure Debugging Options. In Visual Studio Go to Debug -> Options and Settings -> Debug node -> General sub node and disable “Enable Just My Code (managed)” Step 4.2: Specify the symbol loading directory options. Specify the locations for Client bin and server bin directories of the installation, remember to specify the correct instance of Server bin directory corresponding to your AOS. Step 4.3: Configure the project for debugging Step 5: Ready to go place your breakpoints in X++ and in .Net wherever necessary before this process... Run the Visual studio project and it will invoke the AX client with your breakpoint hitting X++ code.. and when you do a step-in using F11 the Visual studio debugger will be active and from here onwards you would be able to debug the complete flow. Debugging in seamless manner across debuggers is really very good feature and mostly underutilized, but by doing so we can have improved troubleshooting and saves a hell lot of time.. Stay tuned for more in Advanced Debugging..

• I still think Twitter is dead &hellip; but

  - by Randy Walker

  Twitter finally hit the mainstream about 8 months ago, but I’ve been saying for a couple of years now, without a real way for the company to earn money, what’s the future fate of Twitter?  On the personal side, where is the real value for the users?  For the most part, Twitter has replaced most people’s IM (instant messaging), at least in the technology circles I run in.  It still has value for users as a communication tool.  But I see it more as a fad.  My prediction is over the next 6 months we’ll start seeing a usage drop (if we haven’t already started to see it). On the business side, how does Twitter make money?  It doesn’t.  If you use the text messaging capabilities, you see a few ads.  But most smart phone and PC users, won’t ever see them.  I still think Twitter has the best chance to make money by forcing the “collectors” to pay money.  You know what I mean by “collector”, those people that collect tons of followers or friends.  If Twitter caps the number of followers and makes you pay to have more, would you?  The normal twitter user doesn’t have that many followers, and this is where my title comes in … BUT The financial value for Twitter is really seen through businesses connecting with their customers.  I’ve seen 3 effective ways this has been accomplished. 1. Giving your customers a coupon or announcing a sale My favorite is @amazonmp3, Being a huge music lover, I get notified when they put music on sale. Various restaurants like @ruthschris_ARK will let their favorite customers know about certain specials @BluefinMemphis I was traveling through Memphis once looking for a sushi restaurant when they had %50 off if we mentioned we saw them on Twitter.  It was their first attempt at trying to encourage customers in the door, and after talking with the management, it was a huge success 2. Giveaways @namecheap Several companies have started huge marketing campaigns, but my favorite is watching companies post trivia questions, and the first person to respond wins a prize. 3. Responding to Customer Complaints I once posted a complaint about American Express (a company that I have slowly come to really dislike) but they actually had someone contact me to try and resolve the issue.  I give them credit for paying attention, but still dislike them for their horrible credit practices.

• PayPal India Problems Continues

  - by Ravish

  Reserve Bank of India has been giving hard time to PayPal and its users in India. RBI had previously blocked PayPal transactions in India a few times, and they made it difficult to withdraw payments by enforcing exports and forex related compliance. Here is yet another bad news for Indian PayPal users. With effect from March 1st, Indian users cannot receive payments of more than $500 in your PayPal account. Moreover, you cannot keep or use any funds in your PayPal account. You can use your PayPal balance to make send money for any goods or services, and must withdraw it to your bank account within 7 days of the receipt. These changes have rendered PayPal almost useless for small business, webmasters and publishers. Most webmasters and publishers rely on PayPal to receive payments from advertisers and clients. It has also made it impossible to buy anything online with PayPal. Sending payments abroad via other channels is already a pain, sending a bank wire requires too many formalities, documentation and time. Moreover, you are even required to deduct TDS on payments you make for any products or services. The restrictions will take effect on March 1st, so you have 30 days to complete any pending transactions you may have. This step by RBI is yet another gimmick by corrupt Indian Government to make life difficult of entrepreneurs, kill innovation, slap more taxes and create more channels to take bribes. Following is the notification from PayPal about this issue: As part of our commitment to provide a high level of customer service, we would like to give you a 30-day advance notice on changes to our user agreement for India. With effect from 1 March 2011, you are required to comply with the requirements set out in the notification of the Reserve Bank of India governing the processing and settlement of export-related receipts facilitated by online payment gateways (“RBI Guidelines”). In order to comply with the RBI Guidelines, our user agreement in India will be amended for the following services as follows: Any balance in and all future payments into your PayPal account may not be used to buy goods or services and must be transferred to your bank account in India within 7 days from the receipt of confirmation from the buyer in respect of the goods or services; and Export-related payments for goods and services into your PayPal account may not exceed US$500 per transaction. We seek your understanding as we continue to employ our best efforts to comply with the RBI Guidelines in a timely manner.

• Creating the Completely Customized World Just for YOU

  - by divya.malik

  OK so not a customized world, but do you know what goes into creating that customized web store front for you? How do you get those additional offers from vendors when you call in for service or when you are browsing a storefront. This is what is has been happening behind the scenes.  When a customer calls in a contact center for service, at the end of the conversation, they are offered a new product, or service. But what just transpired was that the CRM system that was in place had routed the call to the right agent, the agent got the pop up screen with the customer information, and the call request  was handled. Then came the decision point to cross-sell and up-sell, The agent got some recommended offers that were created based on analyzed data (this data had been put into a data warehouse, modeled, profiled and rules were implemented e.g.. People with profile X like product Y).  But with this system, what happens is that analytics can be applied to a very small subset. Now comes Real Time Decisioning (RTD), this helps companies make optimal decisions in the context of transactional systems. It enables companies to improve business processes with real time intelligence on every single transaction. RTD is like a service plug-in that you put at the back of your transactional systems and that you  ping to get a recommendation.  It listens to business process flows and data moving through the process, getting all that data, processes all that you can do with that data, and gives out out various offers. It takes a process centric view of analytics rather than just a data centric view. It continuously observes and learns from ever-changing customer behavior and applies those insights to providing real-time decisions and recommendations at any customer touch point. At Oracle we define Real Time Decisioning as “ The solution that addresses a business issue faced by all organizations : how to make accurate decisions, using the most up to date information, in real time…consistently and in large volumes”. Here is a video on recommendation engines that are benefiting from real time decisioning today and see how it is helping online vendors.

• Sony VAIO is booting directly into Windows without showing grub

  - by Rohan Dhruva

  I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!

• Where would my different development rhythm be suitable for the work?

  - by DarenW

  Over the years I have worked on many projects, with some successful and a great benefit to the company, and some total failures with me getting fired or otherwise leaving. What is the difference? Naturally I prefer the former and wish to avoid the latter, so I'm pondering this issue. The key seems to be that my personal approach differs from the norm. I write code first, letting it be all spaghetti and chaos, using whatever tools "fit my hand" that I'm fluent in. I try to organize it, then give up and start over with a better design. I go through cycles, from thinking-design to coding-testing. This may seem to be the same as any other development process, Agile or whatever, cycling between design and coding, but there does seem to be a subtle difference: The methods (ideally) followed by most teams goes design, code; design, code; ... while I'm going code, design; code, design; (if that makes any sense.) Music analogy: some types of music have a strong downbeat while others have prominent syncopation. In practice, I just can't think in terms of UML, specifications and so on, but grok things only by attempting to code and debug and refactor ad-hoc. I need the grounding provided by coding in order to think constructively, then to offer any opinions, advice or solutions to the team and get real work done. In positions where I can initially hack up cowboy code without constraints of tool or language choices, I easily gain a "feel" for the data, requirements etc and eventually do good work. In formalized positions where paperwork and pure "design" comes first and only later any coding (even for small proof-of-concept projects), I am lost at sea and drown. Therefore, I'd like to know how to either 1) change my rhythm to match the more formalized methodology-oriented team ways of doing things, or 2) find positions at organizations where my sense of development rhythm is perfect for the work. It's probably unrealistic for a person to change their fundamental approach to things. So option 2) is preferred. So where I can I find such positions? How common is my approach and where is it seen as viable but different, and not dismissed as undisciplined or cowboy coder ways?

• ADF Code Guidelines

  - by Chris Muir

  During Oracle Open World 2012 the ADF Product Management team announced a new OTN website, the ADF Architecture Square.  While OOW represents a great opportunity to let customers know about new and exciting developments, the problem with making announcements during OOW however is customers are bombarded with so many messages that it's easy to miss something important. So in this blog post I'd like to highlight as part of the ADF Architecture Square website, one of the initial core offerings is a new document entitled ADF Code Guidelines. Now the title of this document should hopefully make it obvious what the document contains, but what's the purpose of the document, why did Oracle create it? Personally having worked as an ADF consultant before joining Oracle, one thing I noted amongst ADF customers who had successfully deployed production systems, that they all approached software development in a professional and engineered way, and all of these customers had their own guideline documents on ADF best practices, conventions and recommendations.  These documents designed to be consumed by their own staff to ensure ADF applications were "built right", typically sourced their guidelines from their team's own expert learnings, and the huge amount of ADF technical collateral that is publicly available.  Maybe from manuals and whitepapers, presentations and blog posts, some written by Oracle and some written by independent sources. Now this is all good and well for the teams that have gone through this effort, gathering all the information and putting it into structured documents, kudos to them.  But for new customers who want to break into the ADF space, who have project pressures to deliver ADF solutions without necessarily working on assembling best practices, creating such a document is understandably (regrettably?) a low priority.  So in recognising this hurdle, at Oracle we've devised the ADF Code Guidelines.  This document sets out ADF code guidelines, practices and conventions for applications built using ADF Business Components and ADF Faces Rich Client (release 11g and greater).  The guidelines are summarized from a number of Oracle documents and other 3rd party collateral, with the goal of giving developers and development teams a short circuit on producing their own best practices collateral. The document is not a final production, but a living document that will be extended to cover new information as discovered or as the ADF framework changes. Readers are encouraged to discuss the guidelines on the ADF EMG and provide constructive feedback to me (Chris Muir) via the ADF EMG Issue Tracker. We hope you'll find the ADF Code Guidelines useful and look forward to providing updates in the near future. Image courtesy of paytai / FreeDigitalPhotos.net

• IE9 Loses Some CSS After Particular Form Submit [migrated]

  - by Asherion

  The site I am editing has a search form. For the record, there are several other forms on the site, contact and the like. This is the only one with an issue. Upon submission of the form, SOME of the styling is lost in IE9 (possibly other versions of IE, haven't tested that yet). Primarily, the margins and colors set in html and body appear to have been lost. Menus, banner, text, etc all appear to retain styles. All styles are on one sheet, that are used here... Any helpful advice? Here is the contents of the search page and the php used to check for the form, if that helps, and the css that I think is lost. THE HTML: <div id="search"> <br /> <div style="float:right;font-size:.8em;"> <form name="form_sidesearch" action="search.html" method="post"> <input type="hidden" name="action" value="search" /> <input type="text" name="search_value" value="<?php echo $systems_primary->search_value ?>" /> <input type="submit" name="submit_search" value="Search Website" /> </form> <br /> </div> </div> <?php echo stripslashes($search_results); THE PHP: <?php // -- Begin Search -------------------------------------------------------------------------------------- if($_REQUEST["action"] === "search") { if(strlen($_REQUEST["pg"]) <= 0) { $_REQUEST["pg"] = 1; } $search_results = $systems_primary->search_website("index",urldecode($_REQUEST["search_value"]),"<div class=\"listing ui-corner-all\"><a href=\"{ENTRY_URL}\" title=\"{ENTRY_TITLE}\" class=\"listing_title\">{ENTRY_TITLE}</a>{ENTRY_CONTENT} <a href=\"{ENTRY_URL}\" title=\"{ENTRY_TITLE}\" style=\"font-size:.8em;\">...read more</a></div><br /><br />",345,"all",10,$_REQUEST["pg"]); } // -- End Search ---------------------------------------------------------------------------------------- ?> THE LOST CSS (could be more): html { background-color:#F6E6C8; font-size:16px; font:Helvetica; } body { width:1027px; margin:0 auto; background-color:#ffffff; font: arial, times new roman, sans-serif; }

• It's called College.

  - by jeffreyabecker

  Today I saw yet another 'GUID vs int as your primary key' article. Like most of the ones I've read this was filled with technical misrepresentations and out-right fallices. Chef's famous line that "There's a time and a place for everything children" applies here. GUIDs have distinct advantages and disadvantages which should be considered when choosing a data type for the primary key. Fallacy 1: "Its easier" An integer data type(tinyint, smallint, int, bigint) is a better artifical key than a GUID because its easier to remember. I'm a firm believer that your artifical primary keys should be opaque gibberish. PK's are an implementation detail which should never be exposed to the user or relied on for business logic. If you want things to come back in an order, add and ORDER BY clause and SortOrder fields. If you want a human-usable look-up add a business key with a unique constraint. If you want to know what order things were inserted into a table add a timestamp. Fallacy 2: "Size Matters" For many applications, the size of the artifical primary key is going to be irrelevant. The particular article which kicked this post off stated repeatedly that joining against an int has better performance than joining against a GUID. In computer science the performance of your algorithm is always a function of the number of data points. This still holds true for databases. Unless your table is very large, the performance difference between an int and a guid probably isnt going to be mesurable let alone noticeable. My personal experience is that the performance becomes an issue when you start having billions of rows in the table. At this point, you should probably start looking to move from int to bigint so the effective space/performance gain isnt as much as you'd think. GUID Advantages: Insert-ability / Mergeability: You can reliably insert guids into tables without key collisions. Database Independence: Saving entities to the database often requires knowing ids. With identity based ids the id must be selected back after every insert. GUIDs can be generated application-side allowing much faster inserts. GUID Disadvantages: Generatability: You can calculate the next id for an integer pk pretty easily in your head but will need a program to generate GUIDs. Solution: "Select top 100 newid() from sysobjects" Fragmentation: most GUID generation algorithms generate pseudo random GUIDs. This can cause inserts into the middle of your clustered index. Solutions: add a default of newsequentialid() or use GuidComb in NHibernate.

• SQL SERVER – Storing 64-bit Unsigned Integer Value in Database

  - by Pinal Dave

  Here is a very interesting question I received in an email just another day. Some questions just are so good that it makes me wonder how come I have not faced it first hand. Anyway here is the question - “Pinal, I am migrating my database from MySQL to SQL Server and I have faced unique situation. I have been using Unsigned 64-bit integer in MySQL but when I try to migrate that column to SQL Server, I am facing an issue as there is no datatype which I find appropriate for my column. It is now too late to change the datatype and I need immediate solution. One chain of thought was to change the data type of the column from Unsigned 64-bit (BIGINT) to VARCHAR(n) but that will just change the data type for me such that I will face quite a lot of performance related issues in future. In SQL Server we also have the BIGINT data type but that is Signed 64-bit datatype. BIGINT datatype in SQL Server have range of -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807). However, my digit is much larger than this number. Is there anyway, I can store my big 64-bit Unsigned Integer without loosing much of the performance of by converting it to VARCHAR.” Very interesting question, for the sake of the argument, we can ask user that there should be no need of such a big number or if you are taking about identity column I really doubt that if your table will grow beyond this table. Here the real question which I found interesting was how to store 64-bit unsigned integer value in SQL Server without converting it to String data type. After thinking a bit, I found a fairly simple answer. I can use NUMERIC data type. I can use NUMERIC(20) datatype for 64-bit unsigned integer value, NUMERIC(10) datatype for 32-bit unsigned integer value and NUMERIC(5) datatype for 16-bit unsigned integer value. Numeric datatype supports 38 maximum of 38 precision. Now here is another thing to keep in mind. Using NUMERIC datatype will indeed accept the 64-bit unsigned integer but in future if you try to enter negative value, it will also allow the same. Hence, you will need to put any additional constraint over column to only accept positive integer there. Here is another big concern, SQL Server will store the number as numeric and will treat that as a positive integer for all the practical purpose. You will have to write in your application logic to interpret that as a 64-bit Unsigned Integer. On another side if you are using unsigned integers in your application, there are good chance that you already have logic taking care of the same.

• TechEd 2010 Day Three: The Database Designer (Isn't)

  - by BuckWoody

  Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

• Xorg.conf (nvidia) Second Monitor getting settings of first

  - by HennyH

  I've been spending the weekend (and some time before that) trying to set up my Korean QHD270 and Benq G2222HDL monitors with Ubuntu 13.10. With the nouveau drivers install both monitor function perfectly fine. After installing the nvidia drivers the Benq works but the QHD270 does not. Now, after days of struggling I managed to get the QHD270 to work following a mixture of blogs, particularly; this one and learnitwithme. Now, unfortunatly my G2222HDL does not work. I fixed the QHD270 by supplying a custom EDID, my xorg.conf looks like so (excluding keyboard and mouse): Section "ServerLayout" Identifier "Layout0" Screen "Default Screen" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Device" Identifier "Configured Video Device" Driver "nvidia" Option "CustomEDID" "DFP:/etc/X11/edid-shimian.bin" EndSection Section "Screen" Identifier "Default Screen" Device "Configured Video Device" Monitor "Configured Monitor" EndSection Now, I tried defining a new Device,Monitor and Screen then in ServerLayout adding Screen "Second Screen" RightOf "Default Screen", but after doing so neither monitor worked. Hoping to fix the issue using a GUI based tool I opened up NVIDIA X Server Settings, which shows my current layout as: It seems that something is being output to the monitor, as suggested by my print screen: Any help would be greatly appreciated. Output of xrandr: Screen 0: minimum 8 x 8, current 5120 x 1440, maximum 16384 x 16384 DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 60.0*+ HDMI-0 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 connected 2560x1440+2560+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 60.0*+ DP-1 disconnected (normal left inverted right x axis y axis) And an extract from my log file (perhaps this is relevant?)
