• Error 5 partition table invalid or corrupt

  - by Clodoaldo

  I'm trying to add a second SSD to a Centos 6 system. But I get the Error 5 partition table invalid or corrupt at boot. The system already has a single SSD (sdb) and a pair of HDDs (sd{a,c}) in a RAID 1 array from where it boots. It is as if the new SSD assumes one of the devices of the RAID array. Is it? How to avoid that or rearrange the setup? # cat fstab UUID=967b4035-782d-4c66-b22f-50244fe970ca / ext4 defaults 1 1 UUID=86fd06e9-cdc9-4166-ba9f-c237cfc43e02 /boot ext4 defaults 1 2 UUID=72552a7a-d8ae-4f0a-8917-b75a6239ce9f /ssd ext4 discard,relatime 1 2 UUID=8000e5e6-caa2-4765-94f8-9caeb2bda26e swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 #

• Duplication of Architecture State means physically extra?

  - by Doopy Doo

  Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. So, this means that there are two sets of basic registers such as Next Instruction Pointer, processor registers like AX, BX, CX etc physically embedded in the micro-processor chip, OR they(arch. state) are made to look two sets by some low level duplication by software/OS.

• Can't create LVM due to: not found (or ignored by filtering)

  I'm planning to use LVM for KVM, and when I try to create a VG it fails, so how can I create my VG and LV ?

• Increase in Available Memory expected by adding 1Gb RAM to a 3Gb Vista 32 bit system

  - by Bob423

  I understand the 32 bit Vista limit in addressing only 4Gb of memory space but I have a very specific question: I have 3Gb installed on a Vista 32 bit system with a 512Mb video card, MSI X-58 board, Intel i7, 920 CPU. System Information currently shows: Installed Memory: 3.00Gb Available Physical Memory: 1.73 Gb My understanding is that the 512Mb video card occupies memory addresses between 4.0Gb and 3.5Gb and so does not subtract from the 3.0Gb of physical memory (correct my understanding if wrong) My Question: If I install another 1Gb of RAM, will my Available Memory increase to 2.73Gb? Thanks, Bob423

• How can I transfer a SQL Server 2005 license?

  - by jdk

  I have the a wrong license number in one SQL Server. What's gone down is this: We virtualized a physical server, effectively cloning its software and licenses - SQL Server included. We want to repurpose the physical machine by keeping SQL Server and modifying its license to another license key that we have purchased. Would prefer not to reinstall SQL Server. Can it be done?

• Hibernate Schema Validation Fails on Oracle Table Synonyms

  - by Rob

  I'm developing a Java web application that uses Hibernate (annotations-based) for persisting entities to an Oracle 11g database. The DBA created synonyms for the tables and requested that I use these synonyms instead of the physical tables. (Eg: Table "Foo" has synonym "S_Foo") If I have "hibernate.hbm2ddl.auto=validate" enabled, then the application fails on startup with "Missing Table: S_Foo". If I turn off the validation, then the app starts up fine and works properly. My guess is that Hibernate only checks against physical tables and not synonyms when validating that a table exists. Is there any way to enable Hibernate schema validation with synonyms? Can I specify both a physical table and a synonym in the annotation? I prefer having that extra safety check that the table structure is correct when the application starts up.

• Database security / scaling question

  - by orokusaki

  Typically I use a database such as MySQL or PostGreSQL on the same machine as the application using it, which makes access easy and secure. I'm just now building the first site that will have a separate physical database server (later this year it will). I'm wondering 3 things: (security) What things should I look into for starters pertaining to security of accessing a separate machine's database? (scalability) Are their scalability issues that I should think about pertaining to this (technology agnostic)? (more ServerFaultish but related) If starting the DB out on the same physical server (using a separate VMWare VM) and later moving to a different physical server, are there implicit problems that I'll have to deal with? Isn't another VM still accessed via localhost? If these questions are completely ludicrous, I apologize to you DB experts.

• C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

  - by HTASSCPP

  I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of logical processors by 2 to determine the number of physical processors. Perphaps I should provide an example: A quad core Intel CPU's with hyperthreading enabled has 4 physical cores, yet 8 logical processors (hyperthreading creates 4 more logical processors). So my current function would detect 8 instead of the desired 4. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED?

• python optparse, how to include additional info in usage output?

  - by CarpeNoctem

  Using python's optparse module I would like to add extra example lines below the regular usage output. My current help_print() output looks like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components I would like it to include usage examples for the less *nix literate users at my work. Something like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components Examples: check_dell -c all check_dell -c fans memory voltage check_dell -s How would I accomplish this? What optparse options allow for such? Current code: import optparse def main(): parser = optparse.OptionParser() parser.add_option('-s', '--storage', action='store_true', default=False, help='checks virtual and physical disks') parser.add_option('-c', '--chassis', action='store_true', default=False, help='checks specified chassis components') (opts, args) = parser.parse_args()

• IIS and Windows 7

  - by xscape

  Hi, Im trying to host my wcf service to IIS. However when I click Basic Settings and Click Test Settings, it has an error. The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again. The version of my IIS is 7.5.7600.16385 and my OS is Windows 7

• Rapid Prototyping for Embedded Systems

  - by dr_pepper

  For doing prototyping on small embedded projects that require physical motion, what hardware prototyping tools are available? For my projects, I tend to spend more time finding parts (i.e. wood, aluminum, etc.) and making the proper cuts, measurements, and connections than writing the software and configuring the electrical hardware. Are there any affordable products that will enable me to create physical hardware that is strong enough to support motion? If not, what techniques or tools are available to help develop the physical hardware more quickly? Currently, I typically build my projects from wood and plastic scraps that I have lying around. What types of materials enable you to prototype more quickly? CLARIFICATION: By motion, I mean something that has to bear stress like a robot arm powered by a servo motor and could handle moving or carrying 1-2 lbs.

• How to disable modifying styles in word 2007?

  - by ldigas

  I'm just getting used to styles (always did the formatting "manually") so this may be overly simple question to some. I wish to modify styles once and for all, and then give that "design" to some of my coleagues, and they will use it to write ... whatever they need to write. But I wish to restrict them from modifying it. I.e. they should be able to make new documents using the given design, but shouldn't be able to modify the design. This make any sense? Any ideas?

• Using the option port on my Watchguard Firebox as a 2nd gateway exit point?

  - by Donovan

  I'm working on a network project in witch I have to design our network to provide two different exit points. The points are differentiated by the path through the corporate network. One of them travels through some monitoring hardware the other does not. We have a Watchguard Firebox in use as our gateway. Currently the network side provides the unmonitored exit point. I was wondering if i hooked the option port to our lan at a point that would force traffic through the monitored path, would it cause any problems? Access to the unmonitored gateway port would be restricted by ip. That would force all others not authorized to point to the monitored gateway port. I thought with the above design i might be able to get away with not having to buy another firebox to achieve the design I want. Thanks, D

• Does software architect/designer require more skills and intellectual than software engineer (implementation)?

  - by Amumu

  So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

• Additional options in MDL

  - by Jane Zhang

      The Metadata Loader(MDL) enables you to populate a new repository as well as transfer, update, or restore a backup of existing repository metadata. It consists of two utilities: metadata export and metadata import. The export utility extracts metadata objects from a repository and writes the information into a file. The import utility reads the metadata information from an exported file and inserts the metadata objects into a repository.      While the Design Client provides an intuitive UI that helps you perform the most commonly used export and import tasks, OMBPlus scripting enables you to specify some additional options, and manage a control file that allows you to perform more specialized export and import tasks. Is it possible to utilize these options in MDL from Design Client? This article will tell you how to achieve it.      A property file named mdl.properties is used to configure the additional options. It stores options in name/value pairs. This file can be created and placed under the directory <owb installation path>/owb/bin/admin/. Below we will introduce the options that can be specified in the mdl.properties file. 1. DEFAULTDIRECTORY     When we open a Metadata Export/Import dialog in Design Client, a default directory is provided for MDL file and log file. For MDL Export, the default directory is <owb installation path>/owb/bin/. As for MDL Import, the default directory is <owb installation path>/owb/mdl/. It may not be the one you would want to use as a default. You can specify the option DEFAULTDIRECTORY in the mdl.properties file to set your own default directory for MDL Export/Import, for example, DEFAULTDIRECOTRY=/tmp/     In this example, the default directory is set to /tmp/. Be sure the value ends with a file separator since it represents a directory. In Windows, the file separator is “\”. In linux, the file separator is “/”. 2. MDLTRACEFILE     Sometimes we would like to trace the whole process of MDL Export/Import, and get detailed information about operations to help developers or supports troubleshooting. To turn on MDL trace, set the option MDLTRACEFILE in the mdl.properties file. MDLTRACEFILE=/tmp/mdl.trc    The right side of the equals sign is to specify the name of the file for MDL trace information to be written. If no path is specified, the file will be placed under directory <owb installation path>/owb/bin/admin/. However, the trace file may be large if the MDL file contains a large number of metadata objects, so please use this option sparingly. 3. CONTROLFILE       We can use a control file to specify how objects are imported or exported. We can set an option called CONTROLFILE in the mdl.properties file, so the control file can also be utilized in Design Client, for example, CONTROLFILE=/tmp/mdl_control_file.ctl     The control file stores options in name/value pairs. When using control file, be sure the file exists, otherwise an exception java.lang.Exception: CNV0002-0031(ERROR): Cannot find specified file will be thrown out during MDL Export/Import.      Next we will introduce some options specified in control file. ZIPFILEFORMAT     By default, MDL exports objects into a zip format file. This zip file has an .mdl extension and contains two files. For example, you export the repository metadata into a file called projects.mdl. When you unzip this MDL file, you obtain two files. The file projects.mdx contains the repository objects. The file mdlcatalog.xml contains internal information about the MDL XML file. Another choice is to combine these two files into one unzip text format file when doing MDL exporting.    In OMBPlus command related to MDL, there is an option called FILE_FORMAT which is used to specify the file format for the exported file. Its acceptable values are ZIP or TEXT. When the value TEXT is selected, the exported file is in text format, for example, OMBEXPORT MDL_FILE '/tmp/options_file_format_test.mdl' FILE_FORMAT TEXT FROM PROJECT 'MY_PROJECT'    How to achieve this via Design Client when doing an MDL exporting? Here we have another option called ZIPFILEFORMAT which has the same function as the FILE_FORMAT. The difference is the acceptable values for ZIPFILEFORMAT are Y or N. When the value is set to N, the exported file is in text format, otherwise it is in zip file format. LOGMESSAGELEVEL     Whenever you export or import repository metadata, MDL writes diagnostic and statistical information to a log file. Their are 3 types of status messages: Informational, Warning and Error. By default, the log file includes all types of message. Sometimes, user may only care about one type of messages, for example, they would like only error messages written to the log file. In order to achieve this, we can set an option called LOGMESSAGELEVEL in control file. The acceptable values for LOGMESSAGELEVEL are ALL, WARNING and ERROR. ALL: If the option LOGMESSAGELEVEL is set to ALL, all types of messages (Informational, Warning and Error) will be written into the log file. WARNING: If the option LOGMESSAGELEVEL is set to WARNING, only warning messages will be written into log file. ERROR: If the option LOGMESSAGELEVEL is set to ERROR, only error messages will be written into log file. UPDATEPROJECTATTRIBUTES, UPDATEMODULEATTRIBUTES      These two options are used to decide whether updating the attributes of projects/modules. The options work when projects/modules being imported already exist in repository and we use update metadata mode or replace metadata mode to do the MDL import. The acceptable values for these two options are Y or N. If the value is set to Y, the attributes of projects/modules will be updated, otherwise not.      Next, let’s give an example to see how these options take effect in MDL. 1. First of all, create the property file mdl.properties under the directory <owb installation path>/owb/bin/admin/. 2. Specify the options in the mdl.properties file, see the following screenshot. 3. Create the control file mdl_control_file.ctl under the directory /tmp/. Set the following options in control file. 4. Log into the OWB Design Client. 5. Create an Oracle module named ORA_MOD_1 under the project MY_PROJECT, then export the project MY_PROJECT into file my_project.mdl. 6. Check the trace file mdl.trc under the directory /tmp/. In this file, we can see very detail information for the above export task. 7. Check the exported MDL file. The file my_project.mdl is in text format. Opening the file, you can see the content of the file directly. It concats the file my_project.mdx and mdlcatalog.xml. 8. Modify the project MY_PROJECT and Oracle module ORA_MOD_1, add descriptions for them separately. Delete the location created in step 5. 9. Import the MDL file my_project.mdl. From the Metadata Import dialog, we can see the default directory for MDL file and log file has been changed to /tmp/. Here we use update metadata mode, match by names to do the importing. 10. After importing, check the description of the project MY_PROJECT, we can see the description is still there. But the description of the Oracle module ORA_MOD_1 has gone. That because we set the option UPDATEPROJECTATTRIBUTES to N, and set the option UPDATEMODULEATTRIBUTES to Y. 11. Check the log file, the log file only contains warning messages and the log message level is set to WARNING.      For more details about the 3 types of status messages, see Oracle® Warehouse Builder Installation and Administration Guide11g Release 2.

Among others, I'll be looking at differences in: Primitives Operators Generics Exceptions Accessibility Collections Delegates and inner classes Concurrency In my next post, I'll start off by looking at the type primitives available in each language, and how Java and C# actually incorporate two different concepts of primitive types in their fundamental language design and use. I'm also thinking of looking at the inner details of Java and the JVM in my blogs, as well as C# and the CLR. If you've got any comments or thoughts on this, please let me know.

• How do you KISS ?

  - by Conor

  The KISS principal is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc The purpose of this question is to derive a checklist of KISS items. I'm especially interested in non-obvious items.

• Evil DRY

  - by StefanSteinegger

  DRY (Don't Repeat Yourself) is a basic software design and coding principle. But there is just no silver bullet. While DRY should increase maintainability by avoiding common design mistakes, it could lead to huge maintenance problems when misunderstood. The root of the problem is most probably that many developers believe that DRY means that any piece of code that is written more then once should be made reusable. But the principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system." So the important thing here is "knowledge". Nobody ever said "every piece of code". I try to give some examples of misusing the DRY principle. Code Repetitions by Coincidence There is code that is repeated by pure coincidence. It is not the same code because it is based on the same piece of knowledge, it is just the same by coincidence. It's hard to give an example of such a case. Just think about some lines of code the developer thinks "I already wrote something similar". Then he takes the original code, puts it into a public method, even worse into a base class where none had been there before, puts some weird arguments and some if or switch statements into it to support all special cases and calls this "increasing maintainability based on the DRY principle". The resulting "reusable method" is usually something the developer not even can give a meaningful name, because its contents isn't anything specific, it is just a bunch of code. For the same reason, nobody will really understand this piece of code. Typically this method only makes sense to call after some other method had been called. All the symptoms of really bad design is evident. Fact is, writing this kind of "reusable methods" is worse then copy pasting! Believe me. What will happen when you change this weird piece of code? You can't say what'll happen, because you can't understand what the code is actually doing. So better don't touch it anymore. Maintainability just died. Of course this problem is with any badly designed code. But because the developer tried to make this method as reusable as possible, large parts of the system get dependent on it. Completely independent parts get tightly coupled by this common piece of code. Changing on the single common place will have effects anywhere in the system, a typical symptom of too tight coupling. Without trying to dogmatically (and wrongly) apply the DRY principle, you just had a system with a weak design. Now you get a system which just can't be maintained anymore. So what can you do against it? When making code reusable, always identify the generally reusable parts of it. Find the reason why the code is repeated, find the common "piece of knowledge". If you have to search too far, it's probably not really there. Explain it to a colleague, if you can't explain or the explanation is to complicated, it's probably not worth to reuse. If you identify the piece of knowledge, don't forget to carefully find the place where it should be implemented. Reusing code is never worth giving up a clean design. Methods always need to do something specific. If you can't give it a simple and explanatory name, you did probably something weird. If you can't find the common piece of knowledge, try to make the code simpler. For instance, if you have some complicated string or collection operations within this code, write some general-purpose operations into a helper class. If your code gets simple enough, its not so bad if it can't be reused. If you are not able to find anything simple and reasonable, copy paste it. Put a comment into the code to reference the other copies. You may find a solution later. Requirements Repetitions by Coincidence Let's assume that you need to implement complex tax calculations for many countries. It's possible that some countries have very similar tax rules. These rules are still completely independent from each other, since every country can change it of its own. (Assumed that this similarity is actually by coincidence and not by political membership. There might be basic rules applying to all European countries. etc.) Let's assume that there are similarities between an Asian country and an African country. Moving the common part to a central place will cause problems. What happens if one of the countries changes its rules? Or - more likely - what happens if users of one country complain about an error in the calculation? If there is shared code, it is very risky to change it, even for a bugfix. It is hard to find requirements to be repeated by coincidence. Then there is not much you can do against the repetition of the code. What you really should consider is to make coding of the rules as simple as possible. So this independent knowledge "Tax Rules in Timbuktu" or wherever should be as pure as possible, without much overhead and stuff that does not belong to it. So you can write every independent requirement short and clean. DRYing try-catch and using Blocks This is a technical issue. Blocks like try-catch or using (e.g. in C#) are very hard to DRY. Imagine a complex exception handling, including several catch blocks. When the contents of the try block as well as the contents of the individual catch block are trivial, but the whole structure is repeated on many places in the code, there is almost no reasonable way to DRY it. try { // trivial code here using (Thingy thing = new thingy) { //trivial, but always different line of code } } catch(FooException foo) { // trivial foo handling } catch (BarException bar) { // trivial bar handling } catch { // trivial common handling } finally { // trivial finally block } The key here is that every block is trivial, so there is nothing to just move into a separate method. The only part that differs from case to case is the line of code in the body of the using block (or any other block). The situation is especially interesting if the many occurrences of this structure are completely independent: they appear in classes with no common base class, they don't aggregate each other and so on. Let's assume that this is a common pattern in service methods within the whole system. Examples of Evil DRYing in this situation: Put a if or switch statement into the method to choose the line of code to execute. There are several reasons why this is not a good idea: The close coupling of the formerly independent implementation is the strongest. Also the readability of the code and the use of a parameter to control the logic. Put everything into a method which takes a delegate as argument to call. The caller just passes his "specific line of code" to this method. The code will be very unreadable. The same maintainability problems apply as for any "Code Repetition by Coincidence" situations. Enforce a base class to all the classes where this pattern appears and use the template method pattern. It's the same readability and maintainability problem as above, but additionally complex and tightly coupled because of the base class. I would call this "Inheritance by Coincidence" which will not lead to great software design. What can you do against it: Ideally, the individual line of code is a call to a class or interface, which could be made individual by inheritance. If this would be the case, it wouldn't be a problem at all. I assume that it is no such a trivial case. Consider to refactor the error concept to make error handling easier. The last but not worst option is to keep the replications. Some pattern of code must be maintained in consistency, there is nothing we can do against it. And no reason to make it unreadable. Conclusion The DRY-principle is an important and basic principle every software developer should master. The key is to identify the "pieces of knowledge". There is code which can't be reused easily because of technical reasons. This requires quite a bit flexibility and creativity to make code simple and maintainable. It's not the problem of the principle, it is the problem of blindly applying a principle without understanding the problem it should solve. The result is mostly much worse then ignoring the principle.

• Visual web page designer for Django?

  - by Robert Oschler

  I'm just starting my Django learning so pardon me if any part of this question is off-base. I have done a lot of web searching for information on the equivalent of a visual web page designer for Django and I don't seem to be getting very far. I have experience with Delphi (Object Pascal), C, C++, Python, PHP, Java, and Javascript and have created and maintained several web sites that included MySQL database dependent content. For the longest time I've been using one of the standard WYSIWIG designers to design the actual web pages, with any needed back end programming done via Forms or AJAX calls that call server side PHP scripts. I have grown tired of the quirks, bugs, and other annoyances associated with the program. Also, I find myself hungry for the functionality and reliability a good MVC based framework would provide me so I could really express myself with custom code easily. So I am turning to Django/Python. However, I'm still a junkie for a good WYSIWIG designer for the layout of web pages. I know there are some out there that thrive on opening up a text editor, possibly with some code editor tools to assist, and pounding out pages. But I do adore a drag and drop editor for simple page layout, especially for things like embedded images, tables, buttons, etc. I found a few open source projects on GitHub but they seem to be focused on HTML web forms, not a generic web page editor. So can I get what I want here? The supreme goal would be to find not only a web page editor that creates Django compatible web pages, but if I dare say it, have a design editor that could add Python code stubs to various page elements in the style of the Delph/VCL or VB design editors. Note, I also have the Wing IDE Professional IDE, version 2.0. As a side note, if you know of any really cool, fun, or time-saving Python libraries that are designed for easy integration into Django please tell me about them. -- roschler
