• Using VirtualBox/VMWare to deploy software to multi sites ?

  - by Sim

  Hi all, I'm currently evaluating the feasibility of using VirtualBox (or VMWare) to deploy the follow project to 10 sites Windows XP MSSQL 2005 Express Edition with Advanced Services JBoss to run 1 in-house software that mostly query master data (customers/products) and feed to other software Why I want to do this ? Because the IT staffs in my 10 sites are not capable enough and the steps taken to setup those "in-house project" are also complicated What are the cons I can forsee ? Need extra power to run that virtualbox instance The IT staffs won't be much knowledgeable 'bout how to install the stuffs Cost (license for VirtualBox in commercial environment as well as extra OS license) I really seek your inputs on the pro/con of this approach, or any links that I can read further Thanks a lot

• SQL Server 2008R2 Express: which is the users limit in a real case scenario?

  - by PressPlayOnTape

  I know that sql server express has not a user limit, and every application has a different way to load/stress the server. But let's take "a typical accounting software", where users input some record, retrieve some data and from time to time they make some custom big queries. May someone share its own experience and tell me which is the limit of users that can realistically use a sql server express instance in this scenario? I am looking for an indicative idea, like (as an example): "I had a company with an average of 40 users logged in and the application was working ok on sql server express, but when the users become 60 the application started to seem non repsonsive" (please note this sentence is pure imagination, I just wrote it as an example).

• Multiple IP Addresses on a Traceroute Line

  - by Paul

  I'm doing a traceroute from my box to ....say.... stackoverflow.com. I see a couple of instances where there are multiple ip's on one line. For instance, in below, line #2 has two IPs: 10.1.6.5 and 10.1.4.5 Also on line #4, there are two timestamps after 216.182.236.96: 0.653 ms and 0.637 ms What are these? This is on Linux Traceroute example: traceroute to www.stackoverflow.com (198.252.206.16), 30 hops max, 60 byte packets 2 ip-10-1-6-5.us-west-1.compute.internal (10.1.6.5) 0.329 ms 0.425 ms ip-10-1-4-5.us-west-1.compute.internal (10.1.4.5) 0.471 ms 4 216.182.236.104 (216.182.236.104) 0.554 ms 216.182.236.96 (216.182.236.96) 0.653 ms 0.637 ms 5 205.251.230.64 (205.251.230.64) 0.616 ms 205.251.229.232 (205.251.229.232) 1.305 ms 205.251.230.64 (205.251.230.64) 0.573 ms

• Confirm that two filesystems are identical, ignoring special files

  - by endolith

  /media/A and /media/B should be identical, but I want to confirm before deleting one. Duplicate file finders don't work, because they'll find two copies of the same file within B, for instance. I only want to confirm that every file in one is identical to the other. diff -qr /media/A/ /media/B/ seems to work, but the output is cluttered with garbage like diff: /media/A//etc/alternatives/ControlPanel: No such file or directory and File /media/A//dev/tty8 is a character special file while file /media/B//dev/tty8 is a character special file I can suppress the former with 2> /dev/null, but I don't know about the latter. rsync -avn /media/A/ /media/B/ also produces a bunch of clutter, like "skipping non-regular file". How can I compare the two trees and just make sure that all the real files exist in both and are identical?

• Pidgin XML

  - by David Totzke

  I'm looking at an xml document that gets passed to a COM object (yes, I said the "C" word) to save a new record.  You can tell by the "new|" at the top of the file before the xml declaration.  If we were saving, there would be "edit|" at the top.  Couldn't you just have a root element with something like: <myRootElement mode="new"> Ah, here's why that won't work... There's no single root element but that's ok because next we find that this document is actually several documents.  <?xml version="1.0"?> appears several times.  The final document opens with <myElementStart> and closes with <myElementEnd> so it's not even well-formed. This isn't a style thing.  This is broken.  I mean, basic well-formed XML only has two rules; three if you count the xml declaration but it works as a document for DTO purposes without it. One root element. Close all elements with a matching tag. As a result, both ends of this conversation need to speak the same dialect of broken XML in order to communicate.  To join the conversation, you must also learn pidgin XML. How can you start out so right - XML being the obvious choice in this instance - and then go so horribly wrong? Dave Just because I can…

• Mac OSX snow leapord move to folder on keystroke

  - by Georges Oates Larsen

  On a weekly basis I have to organize thousands of photos (in groups of up to five thousand) into folders depending upon what they contain (to then narrow them down to the best photos of the same thing). This means I am constantly scanning through photos and organizing them into a folder. THe problem is, the process of stopping my scan, then dragging the photo all the way into a folder myself is bogging me down. Would it be possible to, for instance using something like applescript, or even going so far as using XCode/Cocoa, to create a shortcut that moves whatever I have selected in the finder to a pre-specified folder? Does somethign like this already exist?

• dhclient append settings from multiple DHCP servers

  - by Brian

  I have a server with two interfaces connected to two separate networks, using DHCP for both. When dhclient is writing /etc/resolv.conf, I would like it to append settings that aren't already there. For instance, if I receive from one DHCP server: nameserver 10.0.0.1 search one.mydomain.com and from another: nameserver 10.1.1.254 search two.mydomain.com Then resolv.conf should look like this: search one.mydomain.com two.mydomain.com nameserver 10.0.0.1 nameserver 10.1.1.254 At the moment, it seems the last dhclient overwrites whatever was there. I know I can preconfigure settings in dhclient.conf using supercede or append, but then I have to hard-code the values. I've scoured the man page for dhclient, but it seems like dhclient prefers to work alone (i.e. not in conjunction with any other dhclients)...or am I missing something?

• Is it possible to have non-English regional settings with English day/month names?

  - by Indrek

  I live in Estonia where most regional settings (number, currency and date formats) differ from those used in English-speaking countries. For instance, decimal symbol is comma, thousands separator is space, date format is day-month-year, etc. However, if I set my regional settings to Estonian, then day and month names are also shown in Estonian everywhere: This is slightly annoying since the language used for the rest of Windows is English and I'd like the day and month names to be consistent with it. Is this possible while still keeping the local regional settings? One workaround I've tried is to set regional settings to, say, English (UK) and then customise them to match Estonian settings, but that messes up alphabetic sorting - accented letters like "ö" and "ä" are no longer distinguished from their non-accented versions, and "z" is sorted as last rather than at its correct position in the Estonian alphabet (between "s" and "t"). OS is Windows 7 Professional, in case that matters. Edit: alternatively, if there's no built-in way to accomplish what I want, is it possible to create a custom set of regional settings (like one can create custom keyboard layouts)?

• What if a computer with Ethernet

  - by George Nixon

  I'm just revising for an exam on Networks and Data Communications, and there's one thing I don't get about CSMA/CD and Ethernet. It's supposed to be fairly stable, for instance if a computer drops out of the network, it's not a problem like it might be in a token ring network (I think). But Ethernet works by all the other computers waiting for the currently transmitting computer to finish what it's doing, and then the others use CMSA/CD to determine who goes next. What if one computer malfunctioned and kept sending a continuous stream of data in an infinite loop? In fact, is there a standard time for pcs to transmit before they yield to others?

• How can one-handed work in Emacs be eased?

  - by N.N.

  My right hand is temporarily immobilized and I would like to do some minor work in Emacs, mostly in Org-mode, but also in AUCTeX. Are there ways to ease one-handed work in Emacs, such as some mode or particular work flow? For instance I noticed that for undoing it is easier to press C-x u than C-_ and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands. I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not exactly what I am asking for. I want to ease whatever little time spent one-handed in Emacs (not in general) and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I do realize that I should avoid unnecessary strain. I am using GNU Emacs 23.3.1 in Ubuntu 11.04.

• Reflective discovery of an inner class in an API

  - by wassup

  Let me ask you, as this bothers me for quite a while but appears to be subjectively the best solution for my problem, if reflective discovery of an inner class for API purposes is that bad idea? First, let me explain what I mean by saying "reflective discovery" and all that stuff. I am sketching an API for a Java database system, that'll be centered around block-based entities (don't ask me what that means - that's a long story), and those entities can be read and returned to the Java code as objects subclassed from the Entity class. I have an Entity.Factory class, that, by means of fluent interfaces, takes a Class<? extends Entity> argument and then, uses an instance of Section.Builder, Property.Builder, or whatever builder the entity has, to put it into the back-end storage. The idea about registering all entity types and their builders just doesn't appeal to me, so I thought that the closest solution to the problem that'd suffice my design needs would be to discover, using reflection, all inner classes of Entity classes and find one that's called Builder. Looking for some expert insight :) And if I missed some important design details (which could happen as I tried to make this question as concise as possible), just tell me and I'll add them.

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• Dealing with inflexible programmers.

  - by Singleton

  Sometimes programmers who work on a project for long time get inflexible, and it becomes difficult to reason with them. Even if we do manage to convince them, they can be unlikely to implement our suggestions. For instance, I recently joined a project where the build & release process is too complicated and has unnecessary roadblocks. I suggested that we get rid of some of the development overhead (like filling a few spreadsheets) just by integrating defect management and version control tools (both are IBM-Rational tools so integration can be a very easy one-off effort). Also, if we use tools like Maven & Ant (the project involves Java and some COTS products) build & release can be simplified which should reduce manual errors & intervention. I managed to convince others and I'm ready to put in the effort to develop a proof of concept. But the ‘Senior’ developer is not willing, possibly because the current process makes him more valuable. How do we handle this situation without developing friction in the team?

• VS2012 Coded UI Test closes browser by default

  - by Tarun Arora

  *** Thanks to Steve St. Jean for asking this question and Shubhra Maji for answering this question on the ALM champs list *** 01 – Introduction The default behaviour of coded UI tests running in an Internet Explorer browser has changed between MTM 2010 and MTM 2012. When running a Coded UI test recorded in MTM 2012 or VS 2012 at the end of the test execution the instance of the browser is closed by default. 02 – Description Let’s take an example. As you can see the CloseDinnerNowWeb() method is commented out.  In VS 2010, upon running this test the browser would be left open after the test execution completes. In VS 2012 RTM the behaviour has changed. At the end of the test run, the IE window is closed even though there is no command from the test to do so. In the example below when the test runs, it opens 2 IE windows to the website. When the test run completes both the windows are closed, even though there is no command in the test to close the window. 03 – How to change the CUIT behaviour not to close the IE window after test execution? This change to this functionality in VS 2012 is by design. It is however possible to rollback the behaviour to how it originally was in VS 2010 i.e. the IE window will not close after the test execution unless otherwise commanded by the test to do so. To go back to the original functionality, set BrowserWindow.CloseOnPlaybackCleanup = false More details on the CloseOnPlaybackCleanup property can be found here http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.testtools.uitesting.applicationundertest.closeonplaybackcleanup.aspx  HTH

• How to figure out if hardware is slower than it should be?

  I'm pretty sure that my computer is slower than it should be and it has been that since a got it. For instance it lags a lot in Counter Strike Source. And yes I've installed all the newest drivers. And it doesn't matter what OS I uses. I've tried both Windows, Linux and FreeBSD and it's slow in all of them. So what could this be? Is there something wrong with the hardware? And if, then what could it be?

• Writing Java in Java

  - by Skeith

  I have been using Java for several months at work now and am becoming mildly competent in it. The problem I think I am having is that I program C++ in Java . By that I mean I have always used C++ and am treating Java as a simple syntax change instead of appreciate if for its own language. For instance a static variable in C++ is the same as a normal variable in Java as Java is all classes so they maintain there values between function calls. Little things like this are tripping me up constantly as I am self taught. What I want is to invest the time to become a good java programmer not just a C++ programmer that can write in Java. The problem is I do not know how to do this. I have tried reading the Java doc pages but I find them very clinical and hard to understand. So what I am looking for is recommendations on how I can learn to think in Java. Books that teach Java concepts not Java syntax, online tutorials that I can work through that give it a context, established Java traditions/best practices and any other thing that you could recommend.

• How can I copy the output from a remote command into the local clipboard?

  - by cwd

  I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.

• Strategy for hosting 700+ domains names, each with a static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to manage CNAMEs on the registrar-side, but is there a way to quickly associate CNAMEs with new websites (on the hosting side), maybe using the method offered by gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

• External hard drive issue

  - by Blind Fish

  I am running Ubuntu 12.04 and I have a 500GB external hard drive, formatted in ext4, which I have used for about a year to store batches of data that I am sifting through. About once a week I move a chunk of data from the external drive to my internal drive for processing. As I do that I delete the data from the external drive and empty the trash, thereby clearing up space on the external and also preventing myself from grabbing stuff that I've already sorted through. The vast majority of this is text files, but there are a few .jpegs and .mp4s thrown in, if that matters. Anyway, this has been working without a hitch for nearly a year. So today I plug in the drive and I have an odd issue. I was able to move folders from the external over to my internal drive with no problem, but when I tried to delete those files I was unable to do so. I kept getting the "unable to send file to trash, do you wish to delete permanently?" message. I clicked yes / delete all, but no files were actually deleted. It just sat there. Even worse, while the system was trying in vain to delete those files I was unable to move more files over. In short, I was stuck. I canceled the operation, unmounted and remounted the drive, and then I had an even bigger problem. I have a spreadsheet of all the different folders on there ( exactly 818 ) and yet when I opened the drive in Nautilus, it was only finding 512 folders. So I had 306 missing folders, but my free space was unchanged. Immediately I think that the drive may be corrupted. I went into Disk Utility and ran the check disk option. It said that the drive was NOT clean, but offered no remedy or option to repair. I went back into the drive in Nautilus and once again attempted to delete the files I had already moved. Same issue. I clicked on Details and it said that it was unable to create a trashing file I/O error. I've looked, and it's not a permissions issue. The drive and all folders that are in it all belong to me, and they are all read / write. I've started running badblocks on the drive, but it looks like that is going to take several hours to complete. Any ideas?

• Why is my DB read-only when attached to SQL Express, but not with SQL Web?

  - by David Rubin

  I have an .mdf/.ldf pair, originally created in 2008 R2 Standard, and well under 10GB, with ACLs: d:\db snapshot\DB_NAME.mdf SERVERNAME\SQLServerMSSQLUser$ACCOUNT$MSSQLSERVER:F OWNER RIGHTS:F BUILTIN\Administrators:F d:\db snapshot\DB_NAME_log.ldf SERVERNAME\SQLServerMSSQLUser$ACCOUNT$MSSQLSERVER:F OWNER RIGHTS:F BUILTIN\Administrators:F When I attach the database to an instance of SQL Express 2008 R2, it comes up as read-only. When exactly the same acls and user-accounts and SQLCMD statements are set up with SQL Web 2008 R2, it comes up writable. I looked at MSDN's comparison page but nothing jumped out at me. Why on earth is this happening? Thanks! UPDATE I just noticed that the name of the attached databases are different. On SQL Express (read-only) it matches the filename (e.g. DB_NAME); on SQL Web (writable) it matches the CUSTOM_NAME that I gave it in the attach command: CREATE DATABASE [CUSTOM_NAME] ON (FILENAME = 'PATH_TO_MDF'), (FILENAME = 'PATH_TO_LDF') FOR ATTACH

• Abstract Factory Method and Polymorphism

  - by Scotty C.

  Being a PHP programmer for the last couple of years, I'm just starting to get into advanced programming styles and using polymorphic patterns. I was watching a video on polymorphism the other day, and the guy giving the lecture said that if at all possible, you should get rid of if statements in your code, and that a switch is almost always a sign that polymorphism is needed. At this point I was quite inspired and immediately went off to try out these new concepts, so I decided to make a small caching module using a factory method. Of course the very first thing I have to do is create a switch to decide what file encoding to choose. DANG! class Main { public static function methodA($parameter='') { switch ($parameter) { case 'a': $object = new \name\space\object1(); break; case 'b': $object = new \name\space\object2(); break; case 'c': $object = new \name\space\object3(); break; default: $object = new \name\space\object1(); } return (sekretInterface $object); } } At this point I'm not really sure what to do. As far as I can tell, I either have to use a different pattern and have separate methods for each object instance, or accept that a switch is necessary to "switch" between them. What do you guys think?

• Threading models when talking to hardware devices

  - by Fuzz

  When writing an interface to hardware over a communication bus, communications timing can sometimes be critical to the operation of a device. As such, it is common for developers to spin up new threads to handle communications. It can also be a terrible idea to have a whole bunch of threads in your system, an in the case that you have multiple hardware devices you may have many many threads that are out of control of the main application. Certainly it can be common to have two threads per device, one for reading and one for writing. I am trying to determine the pros and cons of the two different models I can think of, and would love the help of the Programmers community. Each device instance gets handles it's own threads (or shares a thread for a communication device). A thread may exist for writing, and one for reading. Requested writes to a device from the API are buffered and worked on by the writer thread. The read thread exists in the case of blocking communications, and uses call backs to pass read data to the application. Timing of communications can be handled by the communications thread. Devices aren't given their own threads. Instead read and write requests are queued/buffered. The application then calls a "DoWork" function on the interface and allows all read and writes to take place and fire their callbacks. Timing is handled by the application, and the driver can request to be called at a given specific frequency. Pros for Item 1 include finer grain control of timing at the communication level at the expense of having control of whats going on at the higher level application level (which for a real time system, can be terrible). Pros for Item 2 include better control over the timing of the entire system for the application, at the expense of allowing each driver to handle it's own business. If anyone has experience with these scenarios, I'd love to hear some ideas on the approaches used.

• Multilingual sites and Google search results, using sub-folders for language

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site under the subfolder /en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> Alternate languages are setup in the sitemap. (as per Google's recommendations) It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? What are the best practices for ensuring that the correct language version of my website is displayed through Google and other search engines? And how long will it take before the new language version becomes prominent in search engine results?

• Automation Question using VMWare Workstation

  - by James K

  I'm running an experiment that requires me to create 100 instances of Windows XP w/SP3 and saving each VM instance off to a hard drive. I have to annotate the time that the VM load starts (starting my timer when I see the "Setup is preparing...") until the load ends when I see the final desktop after VM loads its drivers. I also have to annotate the host start and stop time. Is there any way this process can be automated? Each load runs me about 16:00 minutes and gets real tiresome after a time. BTW... Exact timing is not necessary, eyeballing as described above is sufficient for my testing needs.
