  • *Code owner* system: is it an efficient way?

    - by sergzach
    There is a new developer in our team. An agile methodology is in use at our company. But the developer has another experience: he considers that particular parts of the code must be assigned to particular developers. So if one developer had created a program procedure or module it would be considered normal that all changes of the procedure/module would be made by him only. On the plus side, supposedly with the proposed approach we save common development time, because each developer knows his part of the code well and makes fixes fast. The downside is that developers don't know the system entirely. Do you think the approach will work well for a medium size system (development of a social network site)?

  • SSIS: Building SQL databases on-the-fly using concatenated SQL scripts

    - by DrJohn
    Over the years I have developed many techniques which help automate the whole SQL Server build process. In my current process, where I need to build entire OLAP data marts on-the-fly, I make regular use of a simple but very effective mechanism to concatenate all the SQL Scripts together from my SSMS (SQL Server Management Studio) projects. This proves invaluable because in two clicks I can redeploy an entire SQL Server database with all tables, views, stored procedures etc. Indeed, I can also use the concatenated SQL scripts with SSIS to build SQL Server databases on-the-fly. You may be surprised to learn that I often redeploy the database several times per day, or even several times per hour, during the development process. This is because the deployment errors are logged and you can quickly see where SQL Scripts have object dependency errors. For example, after changing a table structure you may have forgotten to change any related views. The deployment log immediately points out all the objects which failed to build so you can fix and redeploy the database very quickly. The alternative approach (i.e. doing changes in the database directly using the SSMS UI) would require you to check all dependent objects before making changes. The chances are that you will miss something and wonder why your app returns the wrong data – a common problem caused by changing a table without re-creating dependent views. Using SQL Projects in SSMS A great many developers fail to make use of SQL Projects in SSMS (SQL Server Management Studio). To me they are invaluable way of organizing your SQL Scripts. The screenshot below shows a typical SSMS solution made up of several projects – one project for tables, another for views etc. The key point is that the projects naturally fall into the right order in file system because of the project name. The number in the folder or file name ensures that the projects the SQL scripts are concatenated together in the order that they need to be executed. Hence the script filenames start with 100, 110 etc. Concatenating SQL Scripts To concatenate the SQL Scripts together into one file, I use notepad.exe to create a simple batch file (see example screenshot) which uses the TYPE command to write the content of the SQL Script files into a combined file. As the SQL Scripts are in several folders, I simply use several TYPE command multiple times and append the output together. If you are unfamiliar with batch files, you may not know that the angled bracket (>) means write output of the program into a file. Two angled brackets (>>) means append output of this program into a file. So the command-line DIR > filelist.txt would write the content of the DIR command into a file called filelist.txt. In the example shown above, the concatenated file is called SB_DDS.sql If, like me you place the concatenated file under source code control, then the source code control system will change the file's attribute to "read-only" which in turn would cause the TYPE command to fail. The ATTRIB command can be used to remove the read-only flag. Using SQLCmd to execute the concatenated file Now that the SQL Scripts are all in one big file, we can execute the script against a database using SQLCmd using another batch file as shown below: SQLCmd has numerous options, but the script shown above simply executes the SS_DDS.sql file against the SB_DDS_DB database on the local machine and logs the errors to a file called SB_DDS.log. So after executing the batch file you can simply check the error log to see if your database built without a hitch. If you have errors, then simply fix the source files, re-create the concatenated file and re-run the SQLCmd to rebuild the database. This two click operation allows you to quickly identify and fix errors in your entire database definition.Using SSIS to execute the concatenated file To execute the concatenated SQL script using SSIS, you simply drop an Execute SQL task into your package and set the database connection as normal and then select File Connection as the SQLSourceType (as shown below). Create a file connection to your concatenated SQL script and you are ready to go.   Tips and TricksAdd a new-line at end of every fileThe most common problem encountered with this approach is that the GO statement on the last line of one file is placed on the same line as the comment at the top of the next file by the TYPE command. The easy fix to this is to ensure all your files have a new-line at the end.Remove all USE database statementsThe SQLCmd identifies which database the script should be run against.  So you should remove all USE database commands from your scripts - otherwise you may get unintentional side effects!!Do the Create Database separatelyIf you are using SSIS to create the database as well as create the objects and populate the database, then invoke the CREATE DATABASE command against the master database using a separate package before calling the package that executes the concatenated SQL script.

  • Recovery from URL structure change?

    - by Dejan Pelzel
    in July this year, we have changed the URL structure of the website from: Post: domain.com/blog/post/986/dance/heart-beats-dance-video-by-chinatsu/ Category: domain.com/blog/index/cosplay/ to Post: domain.com/dance/heart-beats-dance-video-by-chinatsu-986/ Category: domain.com/cosplay/ Everything was (supposedly) properly redirected with 301 redirects and it first seemed that the traffic returned after a couple of days, but it has now been close to 2 months and things keep going worse although Google is slowly indexing the changes. What is worrying me even more is that the Pages crawled per day from Webmaster Tools started drastically dropping a few days ago and has just reached a new low in months (from over 2000 to 700). Should I be worried or will things sort out eventually?

  • Switch encoding of terminal with a command

    - by Tomas Lycken
    One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that). I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly. The change I need to do can be performed using the mouse by navigating to "Terminal"-"Set Character Encoding..."-"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen? To clarify: I'm not interested in ways of switching the locale of the system on the remote site - that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

  • The JavaOne 2012 Sunday Technical Keynote

    - by Janice J. Heiss
    At the JavaOne 2012 Sunday Technical Keynote, held at the Masonic Auditorium, Mark Reinhold, Chief Architect, Java Platform Group, stated that they were going to do things a bit differently--"rather than 20 minutes of SE, and 20 minutes of FX, and 20 minutes of EE, we're going to mix it up a little," he said. "For much of it, we're going to be showing a single application, to show off some of the great work that's been done in the last year, and how Java can scale well--from the cloud all the way down to some very small embedded devices, and how JavaFX scales right along with it."Richard Bair and Jasper Potts from the JavaFX team demonstrated a JavaOne schedule builder application with impressive navigation, animation, pop-overs, and transitions. They noted that the application runs seamlessly on either Windows or Macs, running Java 7. They then ran the same application on an Ubuntu Linux machine--"it just works," said Blair.The JavaFX duo next put the recently released JavaFX Scene Builder through its paces -- dragging and dropping various image assets to build the application's UI, then fine tuning a CSS file for the finished look and feel. Among many other new features, in the past six months, JavaFX has released support for H.264 and HTTP live streaming, "so you can get all the real media playing inside your JavaFX application," said Bair. And in their developer preview builds of JavaFX 8, they've now split the rendering thread from the UI thread, to better take advantage of multi-core architectures.Next, Brian Goetz, Java Language Architect, explored language and library features planned for Java SE 8, including Lambda expressions and better parallel libraries. These feature changes both simplify code and free-up libraries to more effectively use parallelism. "It's currently still a lot of work to convert an application from serial to parallel," noted Goetz.Reinhold had previously boasted of Java scaling down to "small embedded devices," so Blair and Potts next ran their schedule builder application on a small embedded PandaBoard system with an OMAP4 chip set. Connected to a touch screen, the embedded board ran the same JavaFX application previously seen on the desktop systems, but now running on Java SE Embedded. (The systems can be seen and tried at four of the nearby JavaOne hotels.) Bob Vandette, Java Embedded Architect, then displayed a $25 Rasberry Pi ARM-based system running Java SE Embedded, noting the even greater need for the platform independence of Java in such highly varied embedded processor spaces. Reinhold and Vandetta discussed Project Jigsaw, the planned modularization of the Java SE platform, and its deferral from the Java 8 release to Java 9. Reinhold demonstrated the promise of Jigsaw by running a modularized demo version of the earlier schedule builder application on the resource constrained Rasberry Pi system--although the demo gods were not smiling down, and the application ultimately crashed.Reinhold urged developers to become involved in the Java 8 development process--getting the weekly builds, trying out their current code, and trying out the new features:http://openjdk.java.net/projects/jdk8http://openjdk.java.net/projects/jdk8/spechttp://jdk8.java.netFrom there, Arun Gupta explored Java EE. The primary themes of Java EE 7, Gupta stated, will be greater productivity, and HTML 5 functionality (WebSocket, JSON, and HTML 5 forms). Part of the planned productivity increase of the release will come from a reduction in writing boilerplate code--through the widespread use of dependency injection in the platform, along with default data sources and default connection factories. Gupta noted the inclusion of JAX-RS in the web profile, the changes and improvements found in JMS 2.0, as well as enhancements to Java EE 7 in terms of JPA 2.1 and EJB 3.2. GlassFish 4 is the reference implementation of Java EE 7, and currently includes WebSocket, JSON, JAX-RS 2.0, JMS 2.0, and more. The final release is targeted for Q2, 2013. Looking forward to Java EE 8, Gupta explored how the platform will provide multi-tenancy for applications, modularity based on Jigsaw, and cloud architecture. Meanwhile, Project Avatar is the group's incubator project for designing an end-to-end framework for building HTML 5 applications. Santiago Pericas-Geertsen joined Gupta to demonstrate their "Angry Bids" auction/live-bid/chat application using many of the enhancements of Java EE 7, along with an Avatar HTML 5 infrastructure, and running on the GlassFish reference implementation.Finally, Gupta covered Project Easel, an advanced tooling capability in NetBeans for HTML5. John Ceccarelli, NetBeans Engineering Director, joined Gupta to demonstrate creating an HTML 5 project from within NetBeans--formatting the project for both desktop and smartphone implementations. Ceccarelli noted that NetBeans 7.3 beta will be released later this week, and will include support for creating such HTML 5 project types. Gupta directed conference attendees to: http://glassfish.org/javaone2012 for everything about Java EE and GlassFish at JavaOne 2012.

  • How can the Ubuntu font be used with LyX or LaTeX?

    - by dv3500ea
    I use LyX for creating documents and would like to be able to format the output of my documents so that they use the Ubuntu font. In the LyX document settings, it appears that there are only a fixed number of fonts available. Is it possible to add the Ubuntu font to this list? If not, is there a way to use the Ubuntu font in LaTeX? I can export the LyX document to LaTeX, make my changes and then use pdflatex & co. to create a formatted document.

  • Delta-update Firefox Aurora package from PPA

    - by ignite
    I am using Firefox Aurora in my Ubuntu 12.04 which I have installed via its ppa (ppa:ubuntu-mozilla-daily/firefox-aurora). As expected of Aurora, I get an update usually after 2-3 days. I have Firefox Aurora installed in Windows too. There also I get updates in 2-3 days but size of update is usually 4-5 MB, while in Ubuntu it's always around 20 MB. What is the reason for this difference? Is there any way by which I can download and install only the changes and not the entire Aurora again and again?

  • Should my colleagues review each others code from source control system?

    - by Daniel Excinsky
    Hi everybody. So that's my story: one of my colleagues uses to review all the code, hosted to revision system. I'm not speaking about adequate review of changes in parts that he belongs to. He watches the code file to file, line to line. Every new file and every modified. I feel just like being spied on! My guess is that if code was already hosted to control system, you should trust it as workable at least. My question is, maybe I'm just too paranoiac and practice of reviewing each others code is good? P.S: We're team of only three developers, and I fear that if there will be more of us, colleague just won't have time to review all the the code we'll write.

  • Mouse pointer size problem

    - by Rasmus Pedersen
    My mouse cursor is double the normal size. Its only the default pointer that is enlarged. Variations like resize, busy and so on are the correct size. The problem persists even when I change cursor theme. If I move the cursor inside a Firefox window it changes to the correct size. My resolution is 2560x1440, its a single screen setup. Nvidia-settings reports my DPI to be: 108x107. I've tired to force that DPI in the LightDM conf, since I figured it must have something to-do with the DPI calculation. I have tried to change the cursor size through dconf but the problem still remains. I haven't seen this problem before, it arrived after the upgrade from Beta 2 to release version of Ubuntu 11.10. Anybody got any idea what the problem might be, its pretty annoying with the huge cursor.

  • After the upgrading to 13.10, I can't input Japanese and Chinese in Emacs

    - by oda
    I have just upgraded Ubuntu from 13.04 to 13.10. It seems iBus have been made big changes.Then I just go to system setting - text entry settings - add "Chinese pinyin" and "Japanese anty" input method. It works well when I input Chinese or Japanese in terminal or .txt file. But when I want to input Chinese and Japanese in Emacs. Even though I have enable ibus-mode in the buffer and change to Chinese pinyin or Japanese anty input method. It just output the English word. Below is the ibus configure in .emacs.By the way, It works well before I upgrade Ubuntu to 13.10 and Emacs to 24.3.1. (add-to-list 'load-path (concat my-emacs-path "/ibus-el-0.3.2")) ;;(setq ibus-python-shell-command-name "python2.7") (require 'ibus) ;; Turn on ibus-mode automatically after loading .emacs (add-hook 'after-init-hook 'ibus-mode-on) (setq ibus-cursor-color '("red" "blue" "limegreen"))

  • Who are the outspoken critics of Object-Oriented design?

    - by Xepoch
    Sure, object-oriented techniques are great and have stuck around for a while. I know only less than a handful of critics of the OO principles. It seems as though most non-OO designs and architectures are shunned, yet we continue to write a lot of good software in C and solve a lot of data changes via awk/sed and countless other examples. Correct tool for the correct job, yes? I'm having a hard time finding articles, presentations, or published criticisms of OO (even Fred Brooks has blessed information hiding). Are there any well-known, published and/or outspoken critics of OO?

  • No root file system - Alternate CD + LVM

    I am trying to install 11.10 as dual boot with Windows 7. I have all partitioned well as you can see here: http://www.flickr.com/photos/42897978@N00/7111180385/ I burned the Alternate CD ISO to a CD. Boot from it and followed instructions to Partitioning. There, I configured the LVM partitions as follows: Volume Group ubuntu-vg - Uses Physical Volume /dev/sda7 380GB - Provides Logical Volume home-lv 60GB - Provides Logical Volume root-lv 60GB - Provides Logical Volume swap-lv 6GB That is all I want (note that my /boot is outside of LVM) Then when I say that all is Ok and to write it to disk and continue with the installation, I get the following error. !! Partition Disks No root file system No root file system is defined Please correct this from the partitioning menu. What should I fix and how? I tried issuing the "Revert changes to partitions", but nothing happens. It seems that the LVM configuration has already been written to the CD. HELP!!

  • ban an IP temporarily after x-many incorrect password attempts

    - by sova
    My new web server got hacked (sigh). I have physical access to my machine (in the near future). It seems like the only changes was a new user account and a borked sudoers file. It seems as though the password was discovered by dictionary searching (I didn't pick it). After I fix these problems (or do a full reinstall?) I want to add a mechanism to ban an IP (for maybe 24 hours or some time limit) after getting the password wrong x number of times, but I'm not a unix sysadmin or anything, so I'm not really sure where to get started. The machine is running Lucid Lynx, from an Ubuntu minimal installation. Thanks,I appreciate your help guys. Hopefully this is the right place for this question.

  • ETPS/" Elantech Touchpad fails detecting single finger

    - by Philipp
    I have a new laptop with an "ETPS/2 Elantech Touchpad". A single finger is only detected, if it is held in such a way that a big area touches the pad. If one touches the pad only with the fingertip, it wil not be detected, both for clicking and for moving the pointer. Strangley, two-finger gestures are detected even if the pad is only touched with the fingertips. On ubuntuusers.de I found that Elantech touchpads require to reload the psmouse-module by: sudo modprobe -r psmouse sudo modprobe psmouse proto=imps If I do this, one finger finally gets detected as it should, but all two or more finger gestures stop working. Also grep -B 5 mouse /proc/bus/input/devices tells that the touchpad now is identified as a mouse, while before the changes it was identified correctly as ETPS/2 Elantech Touchpad.

  • Is catching general exceptions really a bad thing?

    - by Bob Horn
    I typically agree with most code analysis warnings, and I try to adhere to them. However, I'm having a harder time with this one: CA1031: Do not catch general exception types I understand the rationale for this rule. But, in practice, if I want to take the same action regardless of the exception thrown, why would I handle each one specifically? Furthermore, if I handle specific exceptions, what if the code I'm calling changes to throw a new exception in the future? Now I have to change my code to handle that new exception. Whereas if I simply caught Exception my code doesn't have to change. For example, if Foo calls Bar, and Foo needs to stop processing regardless of the type of exception thrown by Bar, is there any advantage in being specific about the type of exception I'm catching?

  • Talking JavaOne with Rock Star Kirk Pepperdine

    - by Janice J. Heiss
    Kirk Pepperdine is not only a JavaOne Rock Star but a Java Champion and a highly regarded expert in Java performance tuning who works as a consultant, educator, and author. He is the principal consultant at Kodewerk Ltd. He speaks frequently at conferences and co-authored the Ant Developer's Handbook. In the rapidly shifting world of information technology, Pepperdine, as much as anyone, keeps up with what's happening with Java performance tuning. Pepperdine will participate in the following sessions: CON5405 - Are Your Garbage Collection Logs Speaking to You? BOF6540 - Java Champions and JUG Leaders Meet Oracle Executives (with Jeff Genender, Mattias Karlsson, Henrik Stahl, Georges Saab) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Ellen Kraffmiller Martijn Verburg, Jeff Genender, and Henri Tremblay) I asked him what technological changes need to be taken into account in performance tuning. “The volume of data we're dealing with just seems to be getting bigger and bigger all the time,” observed Pepperdine. “A couple of years ago you'd never think of needing a heap that was 64g, but today there are deployments where the heap has grown to 256g and tomorrow there are plans for heaps that are even larger. Dealing with all that data simply requires more horse power and some very specialized techniques. In some cases, teams are trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work -- let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one where if you were to even consider using a transaction, you've lost." When asked about the greatest misconceptions about performance tuning that he currently encounters, he said, “If you have a performance problem, you should start looking at code at the very least and for that extra step, whip out an execution profiler. I'm not going to say that I never use execution profilers or look at code. What I will say is that execution profilers are effective for a small subset of performance problems and code is literally the last thing you should look at.And what is the most exciting thing happening in the world of Java today? “Interesting question because so many people would say that nothing exciting is happening in Java. Some might be disappointed that a few features have slipped in terms of scheduling. But I'd disagree with the first group and I'm not so concerned about the slippage because I still see a lot of exciting things happening. First, lambda will finally be with us and with lambda will come better ways.” For JavaOne, he is proctoring for Heinz Kabutz's lab. “I'm actually looking forward to that more than I am to my own talk,” he remarked. “Heinz will be the third non-Sun/Oracle employee to present a lab and the first since Oracle began hosting JavaOne. He's got a great message. He's spent a ton of time making sure things are going to work, and we've got a great team of proctors to help out. After that, getting my talk done, the Java Champion's panel session and then kicking back and just meeting up and talking to some Java heads."Finally, what should Java developers know that they currently do not know? “’Write Once, Run Everywhere’ is a great slogan and Java has come closer to that dream than any other technology stack that I've used. That said, different hardware bits work differently and as hard as we try, the JVM can't hide all the differences. Plus, if we are to get good performance we need to work with our hardware and not against it. All this implies that Java developers need to know more about the hardware they are deploying to.” Originally published on blogs.oracle.com/javaone.

  • How do I install Sublime Text 2?

    - by Michael Gruber
    I installed Sublime Text 2 on 12.04 as per this tutorial. However I don't have adequate permissions when launching the program from the Unity launcher. For example I cannot install packages, or if I add a folder to the sidebar when I close Sublime and reopen, the folder is no longer listed. If I run sudo sublime in the terminal all changes remain after closing. I've tried chown-ing the Sublime Text 2 folder in usr/lib sudo chown -R mylogin:mylogin /usr/lib/"Sublime Text 2" but this seemed to have no effect.

    I'm building a web app and I need a JS framework like Backbone.js to work with my backend rovided by Rails that mostly return JSON objects after DB queries. Searching on the web I've discovered Backbone which seems to be complete, quite populare and actively developed but I've noticed that a lot of things done by Backbone are simply a duplicte of the works done by Rails: for example validation and models. My idea of "perfect" (for my actual needs) JS mvc (it can't be called mvc but i don't have any other names) is something really simple that has a function for each action in my Rails controller that are triggered by a specific event (user/hash changes, click on a button...) and send requests to the server that respond with a JSON object then I'll load a template or execute some JS code. Do you have any concern/suggestion about my idea? Do you know some "micro" js framework like what i have described? If you have worked with backone.js + rails what can you suggest me?

  • Strategies to Defeat Memory Editors for Cheating - Desktop Games

    I'm assuming we're talking about desktop games -- something the player downloads and runs on their local computer. Many are the memory editors that allow you to detect and freeze values, like your player's health. How do you prevent cheating via memory-modifiation? What strategies are effective to combat this kind of cheating? For reference, I know that players can: - Search for something by value or range - Search for something that changed value - Set memory values - Freeze memory values I'm looking for some good ones. Two I use that are mediocre are: Displaying values as a percentage instead of the number (eg. 46/50 = 92% health) A low-level class that holds values in an array and moves them with each change. (For example, instead of an int, I have a class that's an array of ints, and whenever the value changes, I use a different, randomly-chosen array item to hold the value)
