  • Good Scoop: The PeopleSoft/IBM Backstory

    - by [email protected]
    Sometimes you're searching for something online and you find an unrelated, bonus nugget. Last week I stumbled across an interesting blog post from Chris Heller of a PeopleSoft consulting shop in San Ramon, CA called Grey Sparling. I don't know these guys. But Chris, who apparently used to work on the PeopleTools team, wrote a great article on a pre-acquisition, would-be deal between IBM and PeopleSoft that would have standardized PeopleSoft on IBM technology. The behind-the-scenes perspective is interesting. His commentary on the challenges that the company and PeopleSoft customers would have encountered if the deal had gone through was also interesting: ·         "No common ownership. It's hard enough to get large groups of people to work together when they work for the same company, but with two separate companies it is much, much harder. Even within Oracle, progress on Fusion applications was slow until Thomas Kurian took over Fusion applications in addition to Fusion middleware." ·         "No customer buy-in. PeopleSoft customers weren't asking for a conversion to WebSphere, so the fact that doing that could have helped PeopleSoft stay independent wouldn't have meant much to them, especially since the cost of moving to whatever a "PeopleSoft built on WebSphere" would have been significant." ·         "No executive buy-in. This is related to the previous point, but it's worth calling out separately. If Oracle had walked away and the deal with IBM had gone through, and PeopleSoft customers got put through the wringer as part of WebSphere move, all of the PeopleSoft project teams would be put in the awkward position of explaining to their management why these additional costs and headaches were happening. Essentially they would need to "sell" the partnership internally to their own management team. That's not a fun conversation to have." I'm not surprised that something like this was in the works. But I did find the inside scoop and Heller's perspective on the challenges particularly interesting. Especially the advantages of aligning development of applications and infrastructure development under one roof. Here's a link to the whole blog entry.

  • Canonicalization of single, small pages like reviews or product categories

    - by Valorized
    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/"> HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do?

  • Generating Report for NUnit

    - by thangchung
     All source codes for this post can be found at my github.Time ago, I received a request that people ask me how they can generate reports of the results of testing using NUnit? In fact, I may never do this. In the little world of my programming, I only care about the test results, red-green-refactoring, and that was it. When I got that question quite a bit unexpected, I knew that I could use NCover to generate reports, but reports of NCover too simple, it did not give us more details on the number of test cases, test methods, ... And I began to see about creating interesting report for NUnit.I was lucky to find an open source here. Its authors call it NUnit2Report, but one disadvantage is it only running on .NET 1.0. Indeed too old compared to the current version 4.0. And I try to download the preview, but I could not run. I had to open its source code and found that it uses XSLT to convert the output of NUnit results from XML to HTML. Nothing really special, because I also knew that after NUnit run output file extension is XML is created. Author only use this file to convert to HTML using XSLT. And I decided to convert it to. NET 4.0, because I will not have to code from scratch. Conversion work made me take some time, but was lucky that I finally have what I want. Thanks Gilles for the this OSS. I will send a mail to thank him for his efforts but put this out for the OSS. Now I will show people how to do it. I used the auto built NAnt and NUnit for running TestCase, and I use Selenium testing framework. After writing three TestCase using Selenium, I ran NUnit, and got the following results: There are 1 fail and 2s success. In the bin directory of this project will have the NUnit output file as shown below: Then I create a build file, and a bat file for easy running (can use PowerShell is here also.) Double click in the bat file to create a report like this:       Finally open the index.html file in the folder to view report. As everyone can see, it is the TestCase and divide very clearly, that I meet the requirements. This is really good. Once again I really thank NUnit2Report from Gilles. People can contact him via the mail address [email protected] or website  http://nunit2report.sourceforge.net. It really is useful to those who promised to QA. Hopefully this post will help anyone really interested in doing reports for NUnit.

  • Patterns for Handling Changing Property Sets in C++

    - by Bhargav Bhat
    I have a bunch "Property Sets" (which are simple structs containing POD members). I'd like to modify these property sets (eg: add a new member) at run time so that the definition of the property sets can be externalized and the code itself can be re-used with multiple versions/types of property sets with minimal/no changes. For example, a property set could look like this: struct PropSetA { bool activeFlag; int processingCount; /* snip few other such fields*/ }; But instead of setting its definition in stone at compile time, I'd like to create it dynamically at run time. Something like: class PropSet propSetA; propSetA("activeFlag",true); //overloading the function call operator propSetA("processingCount",0); And the code dependent on the property sets (possibly in some other library) will use the data like so: bool actvFlag = propSet["activeFlag"]; if(actvFlag == true) { //Do Stuff } The current implementation behind all of this is as follows: class PropValue { public: // Variant like class for holding multiple data-types // overloaded Conversion operator. Eg: operator bool() { return (baseType == BOOLEAN) ? this->ToBoolean() : false; } // And a method to create PropValues various base datatypes static FromBool(bool baseValue); }; class PropSet { public: // overloaded[] operator for adding properties void operator()(std::string propName, bool propVal) { propMap.insert(std::make_pair(propName, PropVal::FromBool(propVal))); } protected: // the property map std::map<std::string, PropValue> propMap; }; This problem at hand is similar to this question on SO and the current approach (described above) is based on this answer. But as noted over at SO this is more of a hack than a proper solution. The fundamental issues that I have with this approach are as follows: Extending this for supporting new types will require significant code change. At the bare minimum overloaded operators need to be extended to support the new type. Supporting complex properties (eg: struct containing struct) is tricky. Supporting a reference mechanism (needed for an optimization of not duplicating identical property sets) is tricky. This also applies to supporting pointers and multi-dimensional arrays in general. Are there any known patterns for dealing with this scenario? Essentially, I'm looking for the equivalent of the visitor pattern, but for extending class properties rather than methods. Edit: Modified problem statement for clarity and added some more code from current implementation.

  • Time passage arithmetic explanation

    - by Cyber Axe
    I ported this from http://www.effectgames.com/effect/article.psp.html/joe/Old_School_Color_Cycling_with_HTML5 some time ago. However i'm now wanting to modify it for the purpose of changing it from floating point to fixed point maths for enhanced efficiency (for those who are going to talk about premature optimization and what not, i want to have my entire engine in fixed point both as a learning process for me and so i can port code more easily to systems in the future that dont have native floating points such as arm cpus) My initial conversion to fixed points just resulted in the cycling stuck on either the first or last frame of cycling. Plus it would be nice to understand better how it works so i can add more options and so forth in the future, my maths however sucks and the comments are limited so i don't really know how the maths work for determining the frame it shoud use (cycleAmount) I was also a beginner when i ported it as i had no idea between floating points and integers and what not. So in summary my question is, can anyone give an explination of the arithmatic used for determining the cycleAmount (which determings the "frame" of the cycle) This is the working floating point maths version of the code: public final void cycle(Colour[] sourceColours, double timeNow, double speedAdjust) { // Cycle all animated colour ranges in palette based on timestamp. sourceColours = sourceColours.clone(); int cycleSize; double cycleRate; double cycleAmount; Cycle cycle; for (int i = 0, len = cycles.length; i < len; ++i) { cycle = cycles[i]; cycleSize = (cycle.HIGH - cycle.LOW) + 1; cycleRate = cycle.RATE / (int) (CYCLE_SPEED / speedAdjust); cycleAmount = 0; if (cycle.REVERSE < 3) { // Standard Cycle cycleAmount = DFLOAT_MOD((timeNow / (1000 / cycleRate)), cycleSize); if (cycle.REVERSE < 1) { cycleAmount = cycleSize - cycleAmount; // If below 1 make sure its not reversed. } } else if (cycle.REVERSE == 3) { // Ping-Pong cycleAmount = DFLOAT_MOD((timeNow / (1000 / cycleRate)), cycleSize << 1); if (cycleAmount >= cycleSize) { cycleAmount = (cycleSize * 2) - cycleAmount; } } else if (cycle.REVERSE < 6) { // Sine Wave cycleAmount = DFLOAT_MOD((timeNow / (1000 / cycleRate)), cycleSize); cycleAmount = Math.sin((cycleAmount * 3.1415926 * 2) / cycleSize) + 1; if (cycle.REVERSE == 4) { cycleAmount *= (cycleSize / 4); } else if (cycle.REVERSE == 5) { cycleAmount *= (cycleSize >> 1); } } if (cycle.REVERSE == 2) { reverseColours(sourceColours, cycle); } if (USE_BLEND_SHIFT) { blendShiftColours(sourceColours, cycle, cycleAmount); } else { shiftColours(sourceColours, cycle, cycleAmount); } if (cycle.REVERSE == 2) { reverseColours(sourceColours, cycle); } } colours = sourceColours; } // This utility function allows for variable precision floating point modulus. private double DFLOAT_MOD(final double d, final double b) { return (Math.floor(d * PRECISION) % Math.floor(b * PRECISION)) / PRECISION; }

  • Ubuntu Install 11.10 doesn't recognize Windows 7 installation with new HDD

    - by arlendo
    Replaced my crashed HDD with a Seagate 2TB Sata (bought from a company who pulled it from a working computer, OS unknown) and did a fresh install of Windows 7. Windows shows 100MB boot partition (bootable NTFS) and 200GB Windows partition (NTFS), the rest is unallocated. Win7 Disk Management says the partitioning type is Master Boot Record. Win7 boots and runs fine. Ubuntu 11.10 Install procedes to Allocate Drive Space screen and should say This computer currently has Windows 7 on it. What would you like to do? Instead, it says something like Install doesn't detect any existing OS on this computer. When I click on Something else, the partition table shows only the unallocated space of 1.8TB. Ubuntu Disk Utility says Partitioning: Master Boot Record, but GParted Live says Partition Table: gpt. It was my original intention to have the Windows boot partition and application partition, then install Ubuntu 11.10 using boot, root, swap, and home partitions, and maybe another partition just for data (mostly photos). Currently, I would be happy if I could just get Ubuntu installed along with Win7. I am aware of the MBR limits of 3 Primary partitions and 1 Extended partition. I suspect that my new HDD is partitioned for GPT and that is why Ubuntu can't see the Win7 installation. Am I on the right track? I was going to use Windows Disk Management to convert GPT to MBR but I only have the one drive on my AMD-64 mini-computer and it says I have to empty the drive of all partitions before I can access the Convert command. And I can't find any bootable software that would allow me to do that conversion. Here is the result of sudo fdisk -l: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 224 heads, 19 sectors/track, 918004 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xd4a68c18 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 419637247 209715200 7 HPFS/NTFS/exFAT ubuntu@ubuntu:~$ Keep in mind that I'm a definite newbie to screwing around with the inner workings of Ubuntu. I previously had Ubuntu 10.04 running with Vista and I don't remember even having to partition anything that wasn't automatic in the install. Thanks for taking a look here. My Win7 is running fine but I miss my Ubuntu.

  • Business Insight, IT Execution: 9 Project Management Tips

    - by Sylvie MacKenzie, PMP
    Excerpt from Profit Magazine - by David Rosenbaum When Marcos Baccetto was first asked to be the business-side project lead on Eaton Corporation’s Vehicle Group South America (VGSA) Oracle project, the operations services manager responsible for running manufacturing was, he confesses, “a little afraid” because of his lack of IT experience. Today, Baccetto calls the project “a fantastic experience,” and he is a true believer in the benefits of a close relationship between IT implementers and their line-of-business peers. Through his partnership with Jesiele Lima, then VGSA IT manager, Baccetto and Eaton’s South American operations team came to understand several important principles of business and IT. Here he shares nine tips managers should consider when working on an enterprise technology project. 1. Make it a business project, not an IT project. All levels of functional management must have ownership, responsibility, and accountability for the success of the implementation. 2. Share responsibility. Business owners should sign off on tests and data conversion. 3. Clean your data. Dedicating a team to improve core data quality prior to project launch can be a significant time-saver. 4. Select resources properly. Have functional people who can translate business needs to IT and can influence organizational change. 5. Manage scope. Follow project management methodologies and disciplines. 6. Adopt common processes, global solutions. Avoid customized, local solutions. The big-picture business goals can get lost in the details. 7. Implement processes prior to the go-live date. Change management can be key. Keep the workforce informed and train users in advance. 8. Define metrics milestones. Assume there will be a crisis during deployment. Having baseline metrics to compare against will help implementers keep their cool—and the project moving forward. 9. The sponsor’s commitment is critical. It is needed to support the truly difficult decisions.

  • 3D terrain map with Hexagon Grids (XNA)

    - by Rob
    I'm working on a hobby project (I'm a web/backend developer by day) and I want to create a 3D Tile (terrain) engine. I'm using XNA, but I can use MonoGame, OpenGL, or straight DirectX, so the answer does not have to be XNA specific. I'm more looking for some high level advice on how to approach this problem. I know about creating height maps and such, there are thousands of references out there on the net for that, this is a bit more specific. I'm more concerned with is the approach to get a 3D hexagon tile grid out of my terrain (since the terrain, and all 3d objects, are basically triangles). The first approach I thought about is to basically draw the triangles on the screen in the following order (blue numbers) to give me the triangles for terrain (black triangles) and then make hexes out of the triangles (red hex). http://screencast.com/t/ebrH2g5V This approach seems complicated to me since i'm basically having to draw 4 different types of triangles. The next approach I thought of was to use the existing triangles like I did for a square grid and get my hexes from 6 triangles as follows http://screencast.com/t/w9b7qKzVJtb8 This seems like the easier approach to me since there are only 2 types of triangles (i would have to play with the heights and widths to get a "perfect" hexagon, but the idea is the same. So I'm looking for: 1) Any suggestions on which approach I should take, and why. 2) How would I translate mouse position to a hexagon grid position (especially when moving the camera around), for example in the second image if the mouse pointer were the green circle, how would I determine to highlight that hexagon and then translating that into grid coordinates (assuming it is 0,0)? 3) Any references, articles, books, etc - to get me going in the right direction. Note: I've done hex grid's and mouse-grid coordinate conversion before in 2d. looking for some pointers on how to do the same in 3d. The result I would like to achieve is something similar to the following: http :// www. youtube .com / watch?v=Ri92YkyC3fw (sorry about the youtube link, but it will only let me post 2 links in this post... same rep problem i mention below...) Thanks for any help! P.S. Sorry for not posting the images inline, I apparently don't have enough rep on this stack exchange site.

  • I can't install Ubuntu 12.04.1 on iMac G5

    - by user89004
    So, I have this iMac G5 that doesn't have iSight, only a small light sensor I think undernieth, machine model 8.2. I tried burning a Ubuntu 12.04.1 PowerPC 64bit .iso to a cd but the computer just won't boot it, I don't know why. Next I tried with a USB but it wouldn't let me boot that either, I created the usb on my dad's win7 laptop as the process was way easier than on freakin Mac or Ubuntu (no command typing AT ALL on windows) I'm able to get into openfirmware and type boot usb and it does show some weird writing that scrolls so fast I can't see anything and then it just gives me this huge no sign like a stop sign and freezez. The sign is grey and the line in the middle is tilted towards the left. An other issue I'm having with hdiutil is that I can't convert the stupid .iso I just downloaded into a .img because the file keeps on dissapearing right when it's done converting it. I used the syntax from Ubuntu support how to create a bootable usb drive under Mac OS X. I even didn't include the 2 stupid ~ that are shown in the syntax that are completly worthless, God only know why they put them there, and I even tried running the whole thing as root with sudo su before the command. The funny thing is that if I convert something smaller it works. The command I was using is hdiutil convert -format UDRW -o /path/to/target.img /path/to/ubuntu.iso I even tried hdiutil convert /path/to/ubuntu.iso -format UDRW -o /path/to/target.img but the same thing happens, the dummy .img.dmg file dissapears when the conversion is done no matter where I set the output file to go. I have tried several different folders, the same thing happens with all of them. I also tried burning a Ubuntu mini iso on a cd, can't remember if it was 11.10 or 12.10 but even thoguh holding c when the iMac boots up does show me the cd and I can boot from it, I get this weird error upon hitting install, it says something like invalid memory access, release keys and error strings I can't read. I don't have any original DVDs from this iMac and can't run hardware diagnostics. WHatever option I try at the command prompt from the mini ubuntu cd I get the same result, error code and openfirmware backdrop that's frozen. I noticed that the pen drive I created on my dads Win7 laptop is formated with MS-DOS but I can still mount it no problem, so it shouldn't have a problem booting it, right? I used the advice on ubuntu.com to make it, from here. Also, my partition is HFS+ so I can't use it as a hard drive and boot from it. I don' have 2 partitions either, just one HDD, one partition. Please help!!!

  • Reporting on common code smells : A POC

    - by Dave Ballantyne
    Over the past few blog entries, I’ve been looking at parsing TSQL scripts in a variety of ways for a variety of tasks.  In my last entry ‘How to prevent ‘Select *’ : The elegant way’, I looked at parsing SQL to report upon uses of SELECT *.  The obvious question leading on from this is, “Great, what about other code smells ?”  Well, using the language service parser to do that was turning out to be a bit of a hard job,  sure I was getting tokens but no real context.  I wasn't even being told when an end of statement had been reached. One of the other parsing options available from Microsoft is exposed in the assembly ‘Microsoft.SqlServer.TransactSql.ScriptDom’,  this is ,I believe, installed with the client development tools with SQLServer.  It is much more feature rich than the original parser I had used and breaks a TSQL script into intuitive classes for analysis. So, what sort of smells can I now find using it ?  Well, for an opening gambit quite a nice little list. Use of NOLOCK Set of READ UNCOMMITTED Use of SELECT * Insert without column references Explicit datatype conversion on Sargs Cross server selects Non use of two-part naming convention Table and Query hint usage Changes in set options Use of single line comments Use of ordinal column positions in ORDER BY clause Now, lets not argue the point that “It depends” as smells on some of these, but as an academic exercise it is quite interesting.  The code is available from this link :https://www.dropbox.com/s/rfk32sou4fzl2cw/TSQLDomTest.zip  All the usual disclaimers apply to this code, I cannot be held responsible for anything ranging from mild annoyance through to universe destruction due to the use of this code or examples. The zip file contains a powershell script and my test cases.  The assembly used requires .Net 4 to run, which means that you will need powershell 3 ( though im running through PowerGUI and all works ok ) .  The code searches for all .sql files in the folder hierarchy for the workingpath,  you can override this if you want by simply changing the $Folder variable, and processes each in turn for the smells.  Feedback is not great at the moment, all it does is output to an xml file (Smells.xml) the offset position and a description of the smell found. Right now, I am interested in your feedback.  What do you think ?  Is this (or should it be) more than an academic exercise ?  Can tooling such as this be used as some form of code quality measure ?  Does it Work ? Do you have a case listed above which is not being reported ? Do you have a case that you would love to be reported ? Let me know , please mailto: [email protected]. Thanks

  • XRDP: window manager not starting

    - by niboshi
    I have setup my Ubuntu server so that I can connect and login to XRDP from Windows remote desktop. My problem is that after logging in, no window-manager is started. It only displays a single gnome-terminal with no border and gray meshed background. It seems that /usr/sbin/xrdp-sesman itself is running (from observation of ps and /var/run/xrdp/xrdp-sesman.pid). I put debugging line like touch /home/myname/aaaaa into ~/startwm.sh or /etc/xrdp/startwm.sh, but the file aaaaa did not generated after logging in, so these scripts have not been executed.

  • How to correctly partition usb flash drive and which filesystem to choose considering wear leveling?

    - by random1
    Two problems. First one: how to partition the flash drive? I shouldn't need to do this, but I'm no longer sure if my partition is properly aligned since I was forced to delete and create a new partition table after gparted complained when I tried to format the drive from FAT to ext4. The naive answer would be to say "just use default and everything is going to be alright". However if you read the following links you'll know things are not that simple: https://lwn.net/Articles/428584/ and http://linux-howto-guide.blogspot.com/2009/10/increase-usb-flash-drive-write-speed.html Then there is also the issue of cylinders, heads and sectors. Currently I get this: $sfdisk -l -uM /dev/sdd Disk /dev/sdd: 30147 cylinders, 64 heads, 32 sectors/track Warning: The partition table looks like it was made for C/H/S=*/255/63 (instead of 30147/64/32). For this listing I'll assume that geometry. Units = mebibytes of 1048576 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End MiB #blocks Id System /dev/sdd1 1 30146 30146 30869504 83 Linux $fdisk -l /dev/sdd Disk /dev/sdd: 31.6 GB, 31611420672 bytes 255 heads, 63 sectors/track, 3843 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00010c28 So from my current understanding I should align partitions at 4 MiB (currently it's at 1 MiB). But I still don't know how to set the heads and sectors properly for my device. Second problem: file system. From the benchmarks I saw ext4 provides the best performance, however there is the issue of wear leveling. How can I know that my Transcend JetFlash 700's microcontroller provides for wear leveling? Or will I just be killing my drive faster? I've seen a lot of posts on the web saying don't worry the newer drives already take care of that. But I've never seen a single piece of backed evidence of that and at some point people start mixing SSD with USB flash drives technology. The safe option would be to go for ext2, however a serious of tests that I performed showed horrible performance!!! These values are from a real scenario and not some synthetic test: 42 files: 3,429,415,284 bytes copied to flash drive original fat32: 15.1 MiB/s ext4 after new partition table: 10.2 MiB/s ext2 after new partition table: 1.9 MiB/s Please read the links that I posted above before answering. I would also be interested in answers backed up with some references because a lot is said and re-said but then it lacks facts. Thank you for the help.

  • Strange WPF ListBox Behavior

    - by uncle-harvey
    I’m trying to bind a List of items to a listbox in WPF. The items are grouped by one value and each group is to be housed in an expander. Everything works fine when I don’t use any custom styles. However, when I use custom styles (which work properly with non-grouped items and as independent controls) the binding doesn’t display any items. Below is the code I’m executing. Any ideas why the items won’t show up in the Expander?

  • How do I install and use the cli53 tools on Windows?

    - by pavlos
    I'm trying to find the simplest way to import a large number of BIND zone files in to Route 53. I've had a quick look at the AWS CLI and AWS Tools for Windows PowerShell but they don't seem to include a zone file import option like the AWS Route53 GUI does. The cli53 utility on the other hand does, but is written in Python and appears to have a series of pre-requisites to get going which I'm having troubles working out for Windows. I can find plenty of examples of setting it up under Linux but only one reference to a PowerShell example here, but it doesn't explain how to install cli53 in the first place. The other option I'm exploring is to use the BIND to Amazon Route 53 Conversion Tool perl script to first convert the zone files to the Route53 CreateHostedZoneRequest XML format and then use the AWS New-R53HostedZone PowerShell cmdlet to import the zones. After the zones have been imported I'll be looking at running a script to validate what has been created in Route53 matches with the existing nameserver prior to updating each domains nameserver records - I was planning on whipping something up using the new PS4.0 Resolve-DnsName cmdlet, but let me know if you have any better suggestions. Any assistance would be greatly appreciated - thanks. (By the way, I had more reference links in my post but ServerFault won't allow me to post more than 2 links being a new member; and for this same reason I also can't comment on Vasili's example in the other linked thread)

  • alias gcc='gcc -fpermissive' or modifying ./configure script

    - by robo
    I am compiling quite big project from source. The compilation always ends with: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive] I have already compiled this project one year ago. So I know a solution to this. Actualy I found more solutions: Adding a typecast to appropriate line of cpp code (It went to endless number of changes in each file. So I found next solution.) Modifying a makefile to compile that file with -fpermissive option. (I had to modify a lot of lines in each makefile. So I find even better solution.) "g++" or "gcc" was stored in a variable so I added -fpermissive to these variables. This is the best solution I have. It is sufficient to add this option to each makefile once. Unfortunately this software has big number of subdirectories. So I need to modify more than 100 makefiles. It took me whole day one year ago. Is there a way how to do this faster. What about this? alias gcc='gcc -fpermissive' I am not familiar with aliases. But it should be easy to try this. Is the syntax correct? And is this one correct? alias g++='g++ -fpermissive' ? And do I need to export the alias somehow? Will the make program respect the alias? Should I maybe change ./configure script? Or the ./configure.in? Or other file?

  • Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

    - by Philip Durbin
    I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above? Here's a bit more detail about my setup: [root@kvm01b ~]# cat /etc/redhat-release CentOS release 6.2 (Final) [root@kvm01b ~]# rpm -q virt-v2v virt-v2v-0.8.3-5.el6.x86_64 See also Bug 605334 – VirtIO driver for windows does not show specific OS: Windows 7, Windows 2003

  • Oracle Database 12c Spatial: Vector Performance Acceleration

    - by Okcan Yasin Saygili-Oracle
    Most business information has a location component, such as customer addresses, sales territories and physical assets. Businesses can take advantage of their geographic information by incorporating location analysis and intelligence into their information systems. This allows organizations to make better decisions, respond to customers more effectively, and reduce operational costs – increasing ROI and creating competitive advantage. Oracle Database, the industry’s most advanced database,  includes native location capabilities, fully integrated in the kernel, for fast, scalable, reliable and secure spatial and massive graph applications. It is a foundation for deploying enterprise-wide spatial information systems and locationenabled business applications. Developers can extend existing Oracle-based tools and applications, since they can easily incorporate location information directly in their applications, workflows, and services. Spatial Features The geospatial data features of Oracle Spatial and Graph option support complex geographic information systems (GIS) applications, enterprise applications and location services applications. Oracle Spatial and Graph option extends the spatial query and analysis features included in every edition of Oracle Database with the Oracle Locator feature, and provides a robust foundation for applications that require advanced spatial analysis and processing in the Oracle Database. It supports all major spatial data types and models, addressing challenging business-critical requirements from various industries, including transportation, utilities, energy, public sector, defense and commercial location intelligence. Network Data Model Graph Features The Network Data Model graph explicitly stores and maintains a persistent data model withnetwork connectivity and provides network analysis capability such as shortest path, nearest neighbors, within cost and reachability. It loads partitioned networks into memory on demand, overcomingthe limitations of in-memory analysis. Partitioning massive networks into manageable sub-networkssimplifies the network analysis. RDF Semantic Graph Features RDF Semantic Graph has native support for World Wide Web Consortium standards. It has open, scalable, and secure features for storing RDF/OWL ontologies anddata; native inference with OWL 2, SKOS and user-defined rules; and querying RDF/OWL data withSPARQL 1.1, Java APIs, and SPARQLgraph patterns in SQL. Video: Oracle Spatial and Graph Overview Oracle spatial is embeded on oracle database product. So ,we can use oracle installer (OUI).The Oracle Universal Installer (OUI) is used to install Oracle Database software. OUI is a graphical user interface utility that enables you to view the Oracle software that is installed on your machine, install new Oracle Database software, and delete Oracle software that you no longer need to use. Online Help is available to guide you through the installation process. One of the installation options is to create a database. If you select database creation, OUI automatically starts Oracle Database Configuration Assistant (DBCA) to guide you through the process of creating and configuring a database. If you do not create a database during installation, you must invoke DBCA after you have installed the software to create a database. You can also use DBCA to create additional databases. For installing Oracle Database 12c you may check the Installing Oracle Database Software and Creating a Database tutorial under the Oracle Database 12c 2-Day DBA Series.You can always check if spatial is available in your database using  "select comp_id, version, status, comp_name from dba_registry where comp_id='SDO';"   One of the most notable improvements with Oracle Spatial and Graph 12c can be seen in performance increases in vector data operations. Enabling the Spatial Vector Acceleration feature (available with the Spatial option) dramatically improves the performance of commonly used vector data operations, such as sdo_distance, sdo_aggr_union, and sdo_inside. With 12c, these operations also run more efficiently in parallel than in prior versions through the use of metadata caching. For organizations that have been facing processing limitations, these enhancements enable developers to make a small set of configuration changes and quickly realize significant performance improvements. Results include improved index performance, enhanced geometry engine performance, optimized secondary filter optimizations for Spatial operators, and improved CPU and memory utilization for many advanced vector functions. Vector performance acceleration is especially beneficial when using Oracle Exadata Database Machine and other large-scale systems. Oracle Spatial and Graph vector performance acceleration builds on general improvements available to all SDO_GEOMETRY operations in these areas: Caching of index metadata, Concurrent update mechanisms, and Optimized spatial predicate selectivity and cost functions. These optimizations enable more efficient use of: CPU, Memory, and Partitioning Resulting in substantial query performance improvements.UsageTo accelerate the performance of spatial operators, it is recommended that you set the SPATIAL_VECTOR_ACCELERATION database system parameter to the value TRUE. (This parameter is authorized for use only by licensed Oracle Spatial users, and its default value is FALSE.) You can set this parameter for the whole system or for a single session. To set the value for the whole system, do either of the following:Enter the following statement from a suitably privileged account:   ALTER SYSTEM SET SPATIAL_VECTOR_ACCELERATION = TRUE;Add the following to the database initialization file (xxxinit.ora):   SPATIAL_VECTOR_ACCELERATION = TRUE;To set the value for the current session, enter the following statement from a suitably privileged account:   ALTER SESSION SET SPATIAL_VECTOR_ACCELERATION = TRUE; Checkout the complete list of new features on Oracle.com @ http://www.oracle.com/technetwork/database/options/spatialandgraph/overview/index.html Spatial and Graph Data Sheet (PDF) Spatial and Graph White Paper (PDF)

    iconv -l outputs too few encodings on CentOS 6.5: $ iconv -l 10646-1:1993, 10646-1:1993/UCS4, ANSI_X3.4-1968, ANSI_X3.4-1986, ANSI_X3.4, ASCII, CP367, CSASCII, CSUCS4, IBM367, ISO-10646, ISO-10646/UCS2, ISO-10646/UCS4, ISO-10646/UTF-8, ISO-10646/UTF8, ISO-IR-6, ISO-IR-193, ISO646-US, ISO_646.IRV:1991, OSF00010020, OSF00010100, OSF00010101, OSF00010102, OSF00010104, OSF00010105, OSF00010106, OSF05010001, UCS-2, UCS-2BE, UCS-2LE, UCS-4, UCS-4BE, UCS-4LE, UCS2, UCS4, UNICODEBIG, UNICODELITTLE, US-ASCII, US, UTF-8, UTF8, WCHAR_T But on my Ubuntu the list seems much longer, here is different: CentOS6.5: $ php -a php > echo iconv('utf8', 'gbk', 'abc'); PHP Notice: iconv(): Wrong charset, conversion from `utf8' to `gbk' is not allowed in php shell code on line 1 php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.12 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 Ubuntu 14.04: $ php -a Interactive mode enabled php > echo iconv('utf8', 'gbk', "abc\n"); abc php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.19 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 But I don't want to recompile glibc(this will be huge mount of work), any idea on how to ad new encoding support?

  • Working with barcode fonts in Word

    - by Bob Rivers
    I need to create labels in Microsoft Word 2010 with numbers encoded as barcodes. The barcode's format (ean, code39, upc, etc) does not matter. I have downloaded a barcode conversion font that I found at this site. When I type the number that I want and then I format it with my new font, it produces a barcode. I then print it on an OKI laser printer (1200 dpi). The result seems to be fine, at least for common people. But, when I try to scan it, nothing happens. I tried both with a barcode scanner and a data collector, but neither of them read the barcode. My barcode scanner is working fine, because I can read commercial barcodes printed on products. Does anybody have any advice? How do I do this kind of stuff? I want to do it using Word because I will generate labels using Mail Merge. Therefore using external programs aren't option for me.

  • College Courses through distance learning

    - by Matt
    I realize this isn't really a programming question, but didn't really know where to post this in the stackexchange and because I am a computer science major i thought id ask here. This is pretty unique to the programmer community since my degree is about 95% programming. I have 1 semester left, but i work full time. I would like to finish up in December, but to make things easier i like to take online classes whenever I can. So, my question is does anyone know of any colleges that offer distance learning courses for computer science? I have been searching around and found a few potential classes, but not sure yet. I would like to gather some classes and see what i can get approval for. Class I need: Only need one C SC 437 Geometric Algorithms C SC 445 Algorithms C SC 473 Automata Only need one C SC 452 Operating Systems C SC 453 Compilers/Systems Software While i only need of each of the above courses i still need to take two more electives. These also have to be upper 400 level classes. So i can take multiple in each category. Some other classes I can take are: CSC 447 - Green Computing CSC 425 - Computer Networking CSC 460 - Database Design CSC 466 - Computer Security I hoping to take one or two of these courses over the summer. If not, then online over the regular semester would be ok too. Any help in helping find these classes would be awesome. Maybe you went to a college that offered distance learning. Some of these classes may be considered to be graduate courses too. Descriptions are listed below if you need. Thanks! Descriptions Computer Security This is an introductory course covering the fundamentals of computer security. In particular, the course will cover basic concepts of computer security such as threat models and security policies, and will show how these concepts apply to specific areas such as communication security, software security, operating systems security, network security, web security, and hardware-based security. Computer Networking Theory and practice of computer networks, emphasizing the principles underlying the design of network software and the role of the communications system in distributed computing. Topics include routing, flow and congestion control, end-to-end protocols, and multicast. Database Design Functions of a database system. Data modeling and logical database design. Query languages and query optimization. Efficient data storage and access. Database access through standalone and web applications. Green Computing This course covers fundamental principles of energy management faced by designers of hardware, operating systems, and data centers. We will explore basic energy management option in individual components such as CPUs, network interfaces, hard drives, memory. We will further present the energy management policies at the operating system level that consider performance vs. energy saving tradeoffs. Finally we will consider large scale data centers where energy management is done at multiple layers from individual components in the system to shutting down entries subset of machines. We will also discuss energy generation and delivery and well as cooling issues in large data centers. Compilers/Systems Software Basic concepts of compilation and related systems software. Topics include lexical analysis, parsing, semantic analysis, code generation; assemblers, loaders, linkers; debuggers. Operating Systems Concepts of modern operating systems; concurrent processes; process synchronization and communication; resource allocation; kernels; deadlock; memory management; file systems. Algorithms Introduction to the design and analysis of algorithms: basic analysis techniques (asymptotics, sums, recurrences); basic design techniques (divide and conquer, dynamic programming, greedy, amortization); acquiring an algorithm repertoire (sorting, median finding, strong components, spanning trees, shortest paths, maximum flow, string matching); and handling intractability (approximation algorithms, branch and bound). Automata Introduction to models of computation (finite automata, pushdown automata, Turing machines), representations of languages (regular expressions, context-free grammars), and the basic hierarchy of languages (regular, context-free, decidable, and undecidable languages). Geometric Algorithms The study of algorithms for geometric objects, using a computational geometry approach, with an emphasis on applications for graphics, VLSI, GIS, robotics, and sensor networks. Topics may include the representation and overlaying of maps, finding nearest neighbors, solving linear programming problems, and searching geometric databases.

  • Physical-to-virtual for personal use

    - by Journeyman Geek
    One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?

  • Database types for customer analytics

    - by Drewdavid
    I am exploring a paid solution to start providing better embedded, dashboard-style analytics information to our website customers/account holders, but would like to also offer an in-house development option to our team. The more equipped I am with specifics (such as the subject of this question), the better the adoption rate from the team (or so I have found), regardless of the path we choose Would anyone care to summarize a couple of options for a fast and scalable database type through which we would provide the following: • Daily pageviews to a users account pages (users have between 1 and 1000 pages) • Some calculated/compounded metrics (such as conversion rate, i.e. certain page type viewed to contact form thank you page ratio) • We have about 1,500 members (will need room to grow); the number of concurrently logged in users will for the question's sake be 50 I ask because our developer has balked at providing this level of "over time" granularity (i.e. daily) due to the number of space it would take up in a MYSQL database To avoid a downvote I have asked specifically for more than one option, realizing that different people will have different solutions. I will make amendments to my question if so guided by answering parties Thank you for sharing your valued answers :)
