  • How to deal with a boss who is extremely competitive [closed]

    - by user72101
    Okay, so I recently joined this group. My boss who I reported to, left a while ago and my colleague was made the team lead. We both now report to the same head, but she heads the team I work in. I am not sure on how to deal with various situations. I would imagine a team lead who motivates the rest of the team, and not someone who would take credit for what others do. I am the only one who works at the same geographic location. She is very smart, no doubt about it. Things get to me, for example I work on an issue and email a dev team, she would respond on top of my emails and as she is the lead, people respond to her rather than to me. If there is an email addressed with the head on it, she would get it to faster than I do, even when she knew I am looking into it. The rest of the team keeps asking me questions or help. I find it hard to say no, and I try to help them as i feel I might need their help someday as well. I slack in my own work or I could have used the time to learn things. I feel that she should be the go to person and not me. If one gets the benefits of being a lead, why not the work that goes with it? I feel I am stuck in a very unfortunate situation and am totally helpless about it. Everyday it is something or the other. I work on a project for months and finally when it is about to go live and there was a minor issue and the head started asking questions, she completely stole my thunder on a call. She would not let me speak and I have to actually cut her off to speak up. The ideal would be not to give it a thought and just do the best I can,but I feel I am capable of much more and not able to give my best because of this constant war at work. Neetu

  • Media keys play/pause globally worked in 12.10, not in 13.10

    - by Stéphane Gourichon
    Laptop media keys On Asus n55sf laptop, there are a dedicated keys for volume up, volume down, mute, [play/pause], stop, launch (plus a dozen Fn-key combinations). In 12.10 most worked. (Overall is seems unrelated to desktop environment used, stating it for the sake of completeness.) On Ubuntu 12.10 under XFCE they just worked. That is: when a player like rhythmbox or totem was started, it would alternate between play and pause. Interestingly, if several were started, they would alternate independently. E.g. use mouse to pause rhythmbox, launch totem, and one hit on [play/pause] key would pause one and resume the other. Keys Next,Previous and Stop worked as expected in any program. In 13.10 most still work, but play/skip related ignored. On Xubuntu 13.10 (XFCE too) the volume keys work but the [play/pause], stop, next and prev are ignored. Not tried regular Ubuntu 13.10 (Unity). Search before you ask Here are a few facts: https://wiki.ubuntu.com/Hotkeys/Architecture is ummutable and mentions Ubuntu 9.10. https://wiki.ubuntu.com/Hotkeys/Troubleshooting is also outdated as it mentions /usr/share/doc/udev/README.keymap.txt which no longer exists. On 12.10 and 13.10 versions, at XFCE level (as visible by xfconf-query or using xfce4-settings-manager) there are a couple of shortcut for keys like XF86Calculator or XF86TouchpadToggle but nothing related to volume prev/next/play/stop, which is okay. XF86Audio substring doesn't appear in /etc (which is normal) Kernel-level test: "showkey -s" on console shows that keys Next,Play/Pause,Previous,Stop are keycodes 163,164,165,166. Nothing relevant in /etc about that. Reports https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1072371 and https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1012365 suggest to adjust at udev level. Alas, the udev tutorials I found ( e.g. https://wiki.debian.org/udev ) don't even mention keyboard. A thread in french seems to deal with a similar issue: https://forum.ubuntu-fr.org/viewtopic.php?id=1395051. @sudo evtest /dev/input/event3@, in X as well as on plain console, reports events on key pressed and repeats, but nothing when pressing those media keys. Is udev a dead end ? Questions How did it work in 12.10 ? Through udev ? Something else ? Any other hint ?

  • Securing User Account Details with MySQL

    - by Antoinette O'Sullivan
    Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures. You can learn more about this and many other topics in the MySQL for Database Administrator course. For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security. The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text. The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a: Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule. Live-Virtual Event: Attend a live event from your own desk, choosing from a selection of events on the schedule to suit different timezones.

  • Did I lost my RAID again?

    - by BarsMonster
    Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful so it even can reshape arrays so you can start with a smaller array and the grow it as you need. I've bought 3x1Tb drives and made RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as a spare and run a command to grow array to 7-disk. It started working, but speed was ridiculously slow, ~100kb/sec. AFter processing first 37Mb at such an amasing speed, one of old HDDs fails. I properly shutdown PC and disconnected failed drive. After bootup it appeared it recreated intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlocks, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lost my data again? Any suggestions how can I make it work? OS is Ubuntu Server 10.04.2... PS. Needless to say that data is unaccessible - I cannot mount /dev/md0 as save the most valuable data. You can see my disappointment - the very specific thing I was excited about failed twice taking 5Tb of my data with it.

  • input / output error, drives randomly refusing to read / write

    - by ILMV
    I have an issue with one of our servers running Ubuntu 10.04, it is running BackupPC and collects backups from various machines / servers around the building. On the 8th minute (12:08, 12:18, 12:28 etc) the backups are transferred to an external hard drive, we have three and rotate one drive for another everyday. The problem we are having is we are randomly experiencing input / output errors, when this happens you cannot read / write to the drive, it hasn't unmounted so I can cd to the mount point /media/backup1. The drives are not faulty as it's happening on all of them, so I'm at a loss as to what the problem could be, here is an example of the many errors we get: gzip: stdout: Input/output error /var/lib/backuppc/backuppc_offline: line 47: /media/backup1/Tue/offline.log: Input/output error ls: cannot access /media/backup1/Tue/incr_1083_host1.something.co.uk.tar.gz: Input/output error ls: cannot access /media/backup1/Tue/incr_1088_host1.something.co.uk.tar.gz: Input/output error ls: cannot access /media/backup1/Tue/incr_1089_host1.something.co.uk.tar.gz: Input/output error ls: cannot access /media/backup1/Tue/incr_1090_host1.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 39: /media/backup1/Tue/offline.log: Input/output error /var/lib/backuppc/backuppc_offline: line 44: /media/backup1/Tue/offline.log: Input/output error /var/lib/backuppc/backuppc_offline: line 45: /media/backup1/Tue/incr_1090_host1.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 47: /media/backup1/Tue/offline.log: Input/output error ls: cannot access /media/backup1/Tue/incr_591_tech2.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 44: /media/backup1/Tue/offline.log: Input/output error /var/lib/backuppc/backuppc_offline: line 45: /media/backup1/Tue/incr_591_tech2.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 47: /media/backup1/Tue/offline.log: Input/output error ls: cannot access /media/backup1/Tue/incr_592_tech3.something.co.uk.tar.gz: Input/output error ls: cannot access /media/backup1/Tue/incr_593_tech3.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 44: /media/backup1/Tue/offline.log: Input/output error /var/lib/backuppc/backuppc_offline: line 45: /media/backup1/Tue/incr_593_tech3.something.co.uk.tar.gz: Input/output error /var/lib/backuppc/backuppc_offline: line 47: /media/backup1/Tue/offline.log: Input/output error EDIT » Resolved So it turns out Quamis was right, even though I didn't think it was possible it was actually a problem with the drive. You see we have three drives all formatted to ext2, on two of them we were getting I/O errors frequently, I cam back to Quamis' answer and discovered the fsck command, so ran it against the problems drives: fsck /dev/sdb1 This found and fixed a load of problems on the drive, most probably caused by power outages / unsafe removal of drives etc, as the drives are in the xt2 format they aren't journalled and thus aren't protected against such issues. Drives are now working beautifully, thanks all! :D

  • How does I/O work for large graph databases?

    - by tjb1982
    I should preface this by saying that I'm mostly a front end web developer, trained as a musician, but over the past few years I've been getting more and more into computer science. So one idea I have as a fun toy project to learn about data structures and C programming was to design and implement my own very simple database that would manage an adjacency list of posts. I don't want SQL (maybe I'll do my own query language? I'm just having fun). It should support ACID. It should be capable of storing 1TB let's say. So with that, I was trying to think of how a database even stores data, without regard to data structures necessarily. I'm working on linux, and I've read that in that world "everything is a file," including hardware (like /dev/*), so I think that that obviously has to apply to a database, too, and it clearly does--whether it's MySQL or PostgreSQL or Neo4j, the database itself is a collection of files you can see in the filesystem. That said, there would come a point in scale where loading the entire database into primary memory just wouldn't work, so it doesn't make sense to design it with that mindset (I assume). However, reading from secondary memory would be much slower and regardless some portion of the database has to be in primary memory in order for you to be able to do anything with it. I read this post: Why use a database instead of just saving your data to disk? And I found it difficult to understand how other databases, like SQLite or Neo4j, read and write from secondary memory and are still very fast (faster, it would seem, than simply writing files to the filesystem as the above question suggests). It seems the key is indexing. But even indexes need to be stored in secondary memory. They are inherently smaller than the database itself, but indexes in a very large database might be prohibitively large, too. So my question is how is I/O generally done with large databases like the one I described above that would be at least 1TB storing a big adjacency list? If indexing is more or less the answer, how exactly does indexing work--what data structures should be involved?

  • How to get my IR remote to work? Lirc can't see it

    - by user1234567
    I'm using Ubuntu 11.10 (amd64) and I'm trying to get my infrared remote control working. The IR device is a part of a DVB-T USB stick (Based on a RTL2832u chip). I'm using these drivers - it's the only way of getting this device to work under 11.10 that I found. It's a big impromevent from previous Ubuntu version, where I had to edit the driver's code. The device works quite great - and the IR part of it works, too. The driver's page says that the code it's in alpha stage, but I'm pretty sure that my issue has nothing to do with that. If, and only if driver's module is loaded with parameter rtl2832u_rc_mode=2 (which means "use NEC protocol for IR") the remote kind of works, I can see this by running cat /dev/.. ../input6 - when I press a button, random letters appear. The remote works just like a keyboard, but keys are totally messed up - when I press '5' the volume goes down, etc. I would like to use Lirc to fix that, but Lirc can't detect my device (i.e. irw shows nothing). I suspect, it's because something gets into control of the device and sets it up as a keyboard. Lirc seems to be working, it's KDE settings module works too, but it just doesn't detect the device. The Lirc page describes this issue, but since 2009 - the last year when that page was updated, Ubuntu moved from HAL (described there) to DeviceKit, rendering provided instruction useless. I had a similar issue with my previous remote, but the keys were not messed up so much - the remote was usable, so I gave up trying to get Lirc working. I tried the answer provided here, but it changed nothing. I also tried forcing lircd to use my device, but this didn't work too: for i in /sys/class/input/input* ; do echo -n "$(basename "$i"): "; cat "$i/name"; done shows input0: Power Button input1: Power Button input2: Logitech Logitech USB Keyboard input3: A4Tech PS/2+USB Mouse input6: IR-receiver inside an USB DVB receiver But when I run: lircd -n --device=name='IR*' as root (also tried with the full name) I always see: lircd-0.9.0[3983]: lircd(default) ready, using /var/run/lirc/lircd lircd-0.9.0[3983]: accepted new client on /var/run/lirc/lircd lircd-0.9.0[3983]: could not get file information for name=IR* lircd-0.9.0[3983]: default_init(): No such file or directory lircd-0.9.0[3983]: Failed to initialize hardware So, how to set up Lirc with devinput driver in such case?

  • Configure Jenkins and Tomcat using Puppet on Vagrant

    - by ex3v
    I'm playing with setting up my first Spring + jenkins + Tomcat CI dev environment. For now it's just a test/fun phase, but in the near future I'll be starting new project with my coworkers. That's the reason that I want development environment virtualized and exactly te same on every development machine, as well as on production server. I choosen to use Vagrant and to try to write puppet scripts that not only install everything, but also configure everything so each of us will have the same jenkins plugins, same jenkins and tomcat login and password, and literally after calling vagrant up we are ready to work. What I managed to do so far is installation of stuff needed and port forwarding. My vagrantfile looks like this (comments stripped): VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "precise32" config.vm.box_url = "http://files.vagrantup.com/precise32.box" config.vm.network :forwarded_port, guest: 80, host: 8090 config.vm.network :forwarded_port, guest: 8080, host: 8091 config.vm.network :private_network, ip: "192.168.33.10" config.vm.provision :puppet do |puppet| puppet.manifests_path = "puppet/" puppet.manifest_file = "default.pp" puppet.options = ['--verbose'] end end And this is my puppet file: Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] } class system-update { exec { 'apt-get update': command => 'apt-get update', } $sysPackages = [ "build-essential" ] package { $sysPackages: ensure => "installed", require => Exec['apt-get update'], } } class tomcat { package { "tomcat": ensure => present, require => Class["system-update"], } service { "tomcat": ensure => "running", require => Package["tomcat"], } } class jenkins { package { "jenkins": ensure => present, require => Class["system-update"], } service { "jenkins": ensure => "running", require => Package["jenkins"], } } include system-update include tomcat include jenkins Now, when I hit vagrant provision and go to http://localhost:8091/ I can see jenkins running, so above script works good. Next step is configurating jenkins and tomcat by extending above puppet scripts. I'm pretty green when it comes to CI. After wandering around web I've found few tutorials about jenkins configuration (here's one of them). I really want to move configuration presented in this tutorial to puppet file, so when I spread my vagrantfile and puppet file between my coworkers, I will be sure that everyone has exactly te same setup. Unfortunately I'm also green about using puppet, I don't know how to do this. Any help will be apreciated.

  • Upgrading Code from 2007 to 2010

    - by MOSSLover
    So I’ve been doing some upgrades just to see if things will work from 2007 to 2010.  So far most of the stuff I want works, but obviously there are some things that break.  Did you guys know that in 2007 you could add a webpart to the view pages for lists and libraries without losing the toolbar?  In 2010 the ribbon disappears every time you add a webpart.  So if you are using Scot Hillier’s Codeplex project to hide buttons it will not work the same way, because the ribbon is going to disappear altogether. I have also learned another reason why standalone installations are the bane of my existence.  Nine times out of ten the installation is done using Network Service as the application pool account.  You are wondering why is this bad?  Well, let’s just say the site collection administrator with local admin rights wants to attach the IIS Worker process and debug say a webpart.  Visual Studio 2010 will throw a nasty error that tells you that you are not an administrator.  You will say, but I am an administrator?  I have all the correct group permissions on the server and on SQL and in SharePoint.  Then you will go in and decide let’s add my own admin account just to see if I can attach the debugger and you will notice that works properly.  So the morale of the story is create a separate account on your development environment to run all the SharePoint Services and such.  You don’t need to go all out and create the best practices amount of accounts if it’s just your dev environment.  I would at least create one single account to run all your SharePoint process (Services, SQL, and App Pool).  Also, don’t run a standalone install unless you want to kill kittens (this is a quote from Todd Klindt).  We love kittens they are cute and awesome.  Besides you learn more if you click Complete and just skip standalone.  You will learn how to setup SQL Server 2008 and you will learn how to configure your environment.  It will help you in the long run.  So I have ranted enough for today I figure these are enough tidbits for you this time around.  The two of you who read my blog and I know some of you are friends who don’t understand SharePoint.  I might as well have just done “wahwahwahwah” in Charlie Brown adult speak.  Thanks for reading as usual.  I’ll catch you all when I complain more about the upgrade process and share more tidbits, which will inevitably become a presentation at a conference or two.

  • Unit Testing TSQL

    - by Grant Fritchey
    I went through a period of time where I spent a lot of effort figuring out how to set up unit tests for TSQL. It wasn't easy. There are a few tools out there that help, but mostly it involves lots of programming. well, not as much as before. Thanks to the latest Down Tools Week at Red Gate a new utility has been built and released into the wild, SQL Test. Like a lot of the new tools coming out of Red Gate these days, this one is directly integrated into SSMS, which means you're working where you're comfortable and where you already have lots of tools at your disposal. After the install, when you launch SSMS and get connected, you're prompted to install the tSQLt example database. Go for it. It's a quick way to see how the tool works. I'd suggest using it. It' gives you a quick leg up. The concepts are pretty straight forward. There are a series of CLR commands that you use to configure a test and the test assertions. In between you're calling TSQL, either calls to your structure, queries, or stored procedures. They already have the one things that I always found wanting in database tests, a way to compare tables of results. I also like the ability to create a dummy copy of tables for the tests. It lets you control structures and behaviors so that the tests are more focused. One of the issues I always ran into with the other testing tools is that setting up the tests might require potentially destructive changes to the structure of the database (dropping FKs, etc.) which added lots of time and effort to setting up the tests, making testing more difficult, and therefor, less useful. Functionally, this is pretty similar to the Visual Studio tests and TSQLUnit tests that I used to use. The primary improvement over the Visual Studio tests is that I'm working in SSMS instead of Visual Studio. The primary improvement over TSQLUnit is the SQL Test interface it self. A lot of the functionality is the same, but having a sweet little tool to manage & run the tests from makes a huge difference. Oh, and don't worry. You can still run these tests directly from TSQL too, so automation has not gone away. I'm still thinking about how I'd use this in a dev environment where I also had source control to fret. That might be another blog post right there. I'm just getting started with SQL Test, so this is the first of several blog posts & videos. Watch this space. Try the tool.

  • Can't fix broken packages

    - by AWE
    I am too dumb but determined to use Ubuntu that I paid a professional to install it for me (dualboot 11.10 with Win7). When I came home I got a lot of things from the software center. Skype did not have a download button so I googled it and Ubuntu help told me to do this: sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" and then this: sudo apt-get update && sudo apt-get install skype The terminal told me "that this is potentially harmful..." but I thought it was Ubuntu language meaning "are you sure?" Now the computer is mute. Items cannot be installed or removed until the package catalog is repaired, so I want to repair it but the package operation fails. "sudo aptitude -f install" - command not found Synaptic package manager tells me that I have two broken packages, libc6 and libc6-dev so I do this: sudo apt-get update && sudo apt-get upgrade which tells me to do this: sudo apt-get -f install that ends up like this: Can't exec "locale": No such file or directory at /usr/share/perl5/Debconf/Encoding.pm line 16.

  • Getting away from a customized Magento 1.4 installation - Magento 1.6, OpenCart, or others?

    - by Phil
    I'm dealing with a Magento 1.4.0.0 Community Edition installation with various undocumented changes to the core (mostly integration with an ERP system), an outdated Sweet Tooth Points & Rewards module and some custom payment providers. It also doubles as a mediocre blogging/CMS system. It has one store each for 3 different languages, with about 40 product categories for a few hundred products. [rant] With no prior experience with any PHP e-commerce systems, I find it very difficult to work with. I attempted to install Magento 1.4.0.0 on my local WAMP dev machine, it installs fine, but the main page or search do not show any products no matter what I do in the backend admin panel. I don't know what's wrong with it, and whatever information I googled is either too old or too new from Magento 1.4. Later I'm given FTP access to the testing server, which neither my manager or I have permission to install XDebug on, as apparantly it runs on the same server as the production server (yikes). Trying to learn how Magento works is torture. I spent a week trying to add some fields into the Onepage Checkout before giving up and went to work on something else. The template system, just like the rest of Magento, is a bloated mishmash of overcomplicated directory structures, weird config xml files and EAV databases. I went into 6 different models and several content blocks in the backend just to change what the front page looks like. With little-to-none helpful and clear documentation (unlike CodeIgniter) and various breaking changes between minor point revisions which makes it hard to find useful information, Magento 1.4 is a developer killer. [/rant] The client is planning to redesign the site and has decided it might as well as move on from this unsustainable, hacky, upgrade-unfriendly, developer-unfriendly mess. Magento 1.4 is starting to show its age, with Magento 1.7 coming soon, the client is considering upgrading to Magento 1.6 or 1.7 if it has improved from 1.4. The customizations done to the current Magento 1.4 installation will have to be redone, and a new license for the Sweet Tooth Points & Rewards module will have to be bought. The client is also open to other e-commerce systems. I've looked at OpenCart and it seems to be quite developer friendly with a fairly simple structure. I found some complaints regarding its performance when the shop has thousands of categories or products, but this is not an issue with the current number of products my client has. It seems to be solid ground for easy customization to bring the rewards system and ERP integration over. What should the client upgrade to in this case?

  • Why I Love Microsoft Development

    - by Brian Lanham
    I've been writing software for a while and recently had an opportunity to broaden my horizons and start developing for iOS. We decided to leverage, as much as possible, our existing skills and use MonoTouch and MonoDevelop by Novell.    For those of you who do not know, Mono is a .NET port originally designed for Linux but adapted for other platforms as well. MonoTouch is a port specifically for building iOS applications using the .NET framework. MonoDroid is a port (in CTP-esque release) for Android.   A MISSING COMPONENT - VISUAL DESIGNER   MonoDevelop lacks one very significant component compared with other tools I am using: NO VISUAL DESIGNER. Instead of using an integrated visual designer, MonoDevelop shells to the Mac OS "Interface Builder".  Since MonoDevelop lets me have a "Visual Studio-esque" feel *and* I get to use C#, AND it's FREE, I am gladly willing to overlook this.  In fact, it's not even a question.  Free?  Sure, I'll take it with no Visual Designer.   In my experiences I've grown from UNIX and DOS to .NET development through many steps. Java/JSP/Servlets; Windows; Web; etc. I've been doing .NET for quite a few years and I guess I just got "comfortable" with the tools.   WHY AM I NOT GETTING IT?   Interface Builder (IB) is amazingly confusing for me. I had the opportunity to speak at the Northern VA Code Camp on 12/11/2010. My presentation was "Getting Started with iOS Development using MonoTouch and C#".    At the visual design part of the presentation, I asked one of the 3 or 4 Mac developers in the room about my confusion with the IB. I don't understand why the "Classes" list includes objects. I don't understand what "File's Owner" is. And, most importantly, WHAT THE HECK IS AN OUTLET AND WHY IS IT NECESSARY?!?!?"   His response to these question (especially Outlets): "They did it wrong."   I'm accustom to a visual designer that creates variables for graphical widgets for me. Not IB. Instead, I have to create "Outlets" manually. I still do not understand why and, the explanation from a seasoned Mac developer is that it's wrong. (He received nods of confirmation from the other Mac devs in the room.)   I LOVE MS DEV   I love development for Microsoft platforms using Microsoft development tools. I love Windows 7. I love Visual Studio 2010. I love SQL Server. Azure, Entity Framework, Active Directory, Office, WCF/WF/WPF, etc. are all designed with integration in mind. They are also all designed with developers in mind.   Steve Ballmer recently ranted "It's the developers!" That's why it is relatively quick to build apps using MS tools. Clearly, MS knows that while we usually enjoy building technology solutions, we are here to make money. And we need tools that accelerate our time to market without compromising the power and quality of our solutions.   So, yeah, I am sucking up I guess. But I love Microsoft Development. Thank you, Microsoft, for providing the plethora of great development tools.    P.S. (but please slow down a bit…I'm having trouble keeping up!)

  • Display Driver Issue on an hp TX2-1160ea Notebook

    - by Sam
    I'm new to Linux and recently switched to Ubuntu 11.04 due to my project requirement. My laptop has been freezing and going to black screen of death when I run anything related to display (Share desktop, stream video, etc). Today I went through the Ubuntu forum to install the appropriate graphic driver and, after doing it, I rebooted my PC. It gave an error before login saying "select the recovery mode" and after clicking OK, it didn't give the same error on reboot but I've lost the 11.04 graphical interface and all I see is the interface of Ubuntu v10 with slow visuals (even scrolling up/down on browser is really slow). For the reference, here's a desktop screenshot so that you can understand the situation. Also the laptop is overheating. How can I fix this problem? How can i get the Ubuntu 11.04 view back? I also tried Google, but couldn't find any issue like this.

  • How to force a new Notification in notify-osd to show up without waiting for the earlier one to exit?

    - by Nirmik
    I have made a script(and a .desktop shortcut leading to this script) for starting and stoping xampp... It checks the status of xampp and accordingly either starts or stops xampp. Now i have assigned a notification as soon as the script is started to display "Starting xampp..." or "Stopping xampp..." and then when xampp is started or stopped,it displays "Xampp started..." or "Xampp stopped..." I've used notify-send to show notification as seen in the script below Now the thing is that here,the second notification waits for the 1st one to disappear and then pops up even if xampp has started/stopped. I want the new notification to appear immediately by forcing the earlier one to exit before the completion of its life-cycle. This can be seen to take plce when you activate/deactivate wireless/networking immediately... For example the "Wireless enabled" comes up on selecting enable wireless and if you immediately select disable wireless,the "Wireless disabled" notification comes up without waiting for "Wireless enabled" notification to complete its life-cycle. So how do i achieve this? #!/bin/sh SERVICE='proftpd' if ps ax | grep -v grep | grep $SERVICE /dev/null then notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Stopping XAMPP..." && gksudo /opt/lampp/lampp stop && notify-send -i /opt/lampp/htdocs/xampp/img/logo- small.gif "XAMPP Stoped." else notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Starting XAMPP..." && gksudo /opt/lampp/lampp start && notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "XAMPP Started." fi On the man page for notify-send I found --urgency=LEVEL or -u where levels are low, normal, critical. Is this of any use? making it critical? Also I tried it with the command- notify-send -u=critical"Testing" but that dint work...it gives the error- Unknown urgency criticalTesting specified. Known urgency levels: low, normal, critical. or if I give the command notify-send -u=LOW"Testing" it gives me error missing argument to -u Any relation??

  • How do I set up nvidia graphics adapter to put out 1080p, it seems to be using interlace mode>

    - by keepitsimpleengineer
    After upgrading to 12.04, my mythbuntu client/server seems to be running in 1080i, the clue comes from: [ 1176.117] (II) NVIDIA(0): Setting mode "1920x1080_60i" [ 1231.340] (II) NVIDIA(0): Setting mode "DFP-1:1920x1080_60@1920x1080+0+0" This is from Xorg.0.log. This whole thing started from video tearing when watching Mythtv recordings. It didn't happen in 10.10. Should I use "TVStandard" "HD1080p" in the screen section since this is a dedicated HTPC? It only connects to an HDTV (1080p) via hdmi. Here is the current xorg.conf file: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 270.29 (buildd@allspice) Fri Feb 25 14:42:07 UTC 2011 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Keyboard0" "CoreKeyboard" # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" FontPath "unix/:7100" EndSection # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup #Section "InputDevice" # # generated from default # Identifier "Mouse0" # Driver "mouse" # Option "Protocol" "auto" # Option "Device" "/dev/psaux" # Option "Emulate3Buttons" "no" # Option "ZAxisMapping" "4 5" #EndSection # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup #Section "InputDevice" # # generated from default # Identifier "Keyboard0" # Driver "kbd" #EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "SAMSUNG" HorizSync 26.0 - 81.0 VertRefresh 24.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 240" Option "TripleBuffer" "1" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection After a little digging, the question changes slightly, to wit... Per Chapter 19 of nvidia README... "If the EDID for the display device reported a preferred mode timing, and that mode timing is considered a valid mode, then that mode is used as the "nvidia-auto-select" mode."

  • TomEE Integration in NetBeans Next

    - by Geertjan
    At JavaOne 2013, there was a lot of buzz around the TomEE server, e.g., many Tweets, nice party, and a new TomEE consulting company. For those tracking TomEE developments, it is interesting to note that recently the NetBeans IDE development builds have had added to them... TomEE support. Note: The TomEE support described here is not in NetBeans IDE 7.4, but in development builds for the next release of NetBeans IDE.For example, with NetBeans IDE development builds you're able to: register TomEE as a server in the Services window (TomEE has several distributions, e.g., one can use the "with JAX-RS" one, for example) create a Java EE 6 web project (e.g., Maven based) against this server create JPA entities from database create JAX-RS classes from JPA entities create JSF pages from JPA entities the IDE lets you create a new data source for TomEE and deploy it to the server the IDE figures out the components that are already packaged in TomEE, and the fact that (unlike with regular Tomcat), it does not need to package any components such as JSF implementation, persistence provider, or JAX-RS runtime, so that the resulting WAR file is very small the IDE can also do "deploy on save" with TomEE, so that your development cycle is very fast Adam Bien blogged about how he set up TomEE sometime ago, here. The official support in NetBeans IDE will be much more tightly integrated, simplifying the steps Adam describes. For example, the IDE does step 2 from Adam's blog for you, i.e., it sets up TomEE deployment roles. Moreover, it knows about all the technologies included in TomEE so that it can optimize the packaging; it knows about TomEE's persistence setup; it can work with TomEE data sources, etc. Below you see a Maven-based Java EE 6 PrimeFaces application (all entities and JSF pages generated from a database) deployed to TomEE in NetBeans IDE: And here's the management console for configuring and finetuning TomEE in NetBeans IDE: When I tried out the NetBeans IDE development build and TomEE, to see how everything fits together, I was surprised at how fast TomEE started up. Not sure what they did to it, but seems like a server on steroids. And setting it up in NetBeans IDE was trivial. Add the simple set up of TomEE in NetBeans IDE to the many benefits that the widely praised out of the box NetBeans Maven tools make possible, together with the fact that not one single plugin had to be installed to get everything you see described here up and running... and you have a really powerful combination of dev tools, all for free.

  • Tales of a corrupt SQL log

    - by guybarrette
    Warning: I’m a simple dev, not an all powerful DBA with godly powers. This morning, one of my sites was down and DNN reported a problem with the database.  A quick series of tests revealed that the culprit was a corrupted log file. Easy fix I said, I have daily backups so it’s just a mater of restoring a good copy of the database and log files.  Well, I found out that’s not exactly true.  You see, for this database, I have daily file backups and these are not database backups created by SQL Server. So I restored a set of files from a couple of days ago, stopped the SQL service, copied the files over the bad ones, restarted the service only to find out that SQL doesn’t like when you do that.  It suspects something fishy and marks the database as suspect.  A database marked as suspect can’t be accessed at all.  So now what? I searched throughout the tubes of the InterWeb and found that you can restore from a corrupted log file by creating a new database with the same name as the defective one, then copy the restored database file (the one with data) over the newly created one.  Sweet!  But you still end up with SQL marking the database as suspect but at least, the newly created log is OK.  Well not true, it’s not corrupted but the lack of data makes it not OK for SQL so you need to rebuild the log.  How can you do that when SQL blocks any action the database?  First, you need to change the database status from suspect to emergency.  Then you need to set the database for single access only.  After that, you need to repair the log with DBCC and do the DBA dance.  If you dance long enough, SQL should repair the log file.  Now you need to set the access back to multi user.  Here’s the T-SQL script: use master GO EXEC sp_resetstatus 'MyDatabase' ALTER DATABASE MyDatabase SET EMERGENCY Alter database MyDatabase set Single_User DBCC checkdb('MyDatabase') ALTER DATABASE MyDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE DBCC CheckDB ('MyDatabase', REPAIR_ALLOW_DATA_LOSS) ALTER DATABASE MyDatabase SET MULTI_USER So I guess that I would have been a lot easier to restore a SQL backup.  I can’t really say but the InterWeb seems to say so.  Anyway, lessons learned: Vive la différence: File backups are different then SQL backups. Don’t touch me: SQL doesn’t like when you restore a file over a corrupted one. The more the merrier: You should do both SQL and file backups. WTF?: The InterWeb provides you with dozens of way to deal with the problem but many are SQL 2000 or SQL 2005 only, many are confusing and many are written in strange dialects only DBAs understand. var addthis_pub="guybarrette";

  • Gradle for NetBeans RCP

    - by Geertjan
    Start with the NetBeans Paint Application and do the following to build it via Gradle (i.e., no Gradle/NetBeans plugin is needed for the following steps), assuming you've set up Gradle. Do everything below in the Files or Favorites window, not in the Projects window. In the application directory "Paint Application". Create a file named "settings.gradle", with this content: include 'ColorChooser', 'Paint' Create another file in the same location, named "build.gradle", with this content: subprojects { apply plugin: "announce" apply plugin: "java" sourceSets { main { java { srcDir 'src' } resources { srcDir 'src' } } } } In the module directory "Paint". Create a file named "build.gradle", with this content: dependencies { compile fileTree("$rootDir/build/public-package-jars").matching { include '**/*.jar' } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } Note: The above is a temporary solution, as you can see, the expectation is that the JARs are in the 'build/public-packages-jars' folder, which assumes an Ant build has been done prior to the Gradle build. Now run 'gradle classes' in the "Paint Application" folder and everything will compile correctly. So, this is how the Paint Application now looks: Preferable to the second 'build.gradle' would be this, which uses the JARs found in the NetBeans Platform... netbeansHome = '/home/geertjan/netbeans-dev-201111110600' dependencies { compile files("$rootDir/ColorChooser/release/modules/ext/ColorChooser.jar") def projectXml = new XmlParser().parse("nbproject/project.xml") projectXml.configuration.data."module-dependencies".dependency."code-name-base".each { if (it.text().equals('org.openide.filesystems')) { def dep = "$netbeansHome/platform/core/"+it.text().replace('.','-')+'.jar' compile files(dep) } else if (it.text().equals('org.openide.util.lookup') || it.text().equals('org.openide.util')) { def dep = "$netbeansHome/platform/lib/"+it.text().replace('.','-')+'.jar' compile files(dep) } else { def dep = "$netbeansHome/platform/modules/"+it.text().replace('.','-')+'.jar' compile files(dep) } } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } However, when you run 'gradle classes' with the above, you get an error like this: geertjan@geertjan:~/NetBeansProjects/PaintApp1/Paint$ gradle classes :Paint:compileJava [ant:javac] Note: Attempting to workaround javac bug #6512707 [ant:javac] [ant:javac] [ant:javac] An annotation processor threw an uncaught exception. [ant:javac] Consult the following stack trace for details. [ant:javac] java.lang.NullPointerException [ant:javac] at com.sun.tools.javac.util.DefaultFileManager.getFileForOutput(DefaultFileManager.java:1058) No idea why the above happens, still trying to figure it out. Once the above works, we can start figuring out how to use the NetBeans Maven repo instead and then the user of the plugin will be able to select whether to use local JARs or JARs from the NetBeans Maven repo. Many thanks to Hans Dockter who put the above together with me today, via Skype!

  • Is there any good hosting for asp.net and MySQL

    - by HAJJAJ
    HI every one ,I have account with one of the hosting company, and i did my project in asp.net and I used MySQL for the database. the hosting company is not giving me the full privileges to create new user or to create new stored procedure!!! this is what they said for me: Due to the shared nature of our environment we had to make some modifications to your procedure (namely the definer). We also had to review your procedure to determine if it would be compatible with our environment. While your procedures will work (via phpMyAdmin or some other interface), it is unlikely they will be accessible via the Connector/.NET (ADO.NET) that your application is likely using. This is due to a security restriction with how that connector works in shared environments. http://dev.mysql.com/doc/refman/5.0/en/connector-net-programming-stored.html "Note When you call a stored procedure, the command object makes an additional SELECT call to determine the parameters of the stored procedure. You must ensure that the user calling the procedure has the SELECT privilege on the mysql.proc table to enable them to verify the parameters. Failure to do this will result in an error when calling the procedure." Unfortunately, giving read privileges on the mysql.proc table will give you access to the data of our other customers and that is not an acceptable risk. If your application can only work using stored procedures, then MSSQL will probably be the better option for your site. I apologize for the inconvenience and the wait to have this ticket completed. So is there any good hosting that any body already used it to publish his asp.net and mysql project ??? this is one of my stored procedure and i think it's sample and it will not harm any other uses!!: -- -------------------------------------------------------------------------------- -- Routine DDL -- Note: comments before and after the routine body will not be stored by the server -- -------------------------------------------------------------------------------- DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `SpcategoriesRead`( IN PaRactioncode VARCHAR(5), IN PaRCatID BIGINT, IN PaRSearchText TEXT ) BEGIN -- CREATING TEMPORARY TABLE TO SAVE DATA FROM THE ACTIONCODE SELECTS -- DROP TEMPORARY TABLE IF EXISTS TEMP; CREATE temporary table tmp ( CatID BIGINT primary key not null, CatTitle TEXT, CatDescription TEXT, CatTitleAr TEXT, CatDescriptionAr TEXT, PictureID BIGINT, Published BOOLEAN, DisplayOrder BIGINT, CreatedOn DATE ); IF PaRactioncode = 1 THEN -- Retrive all DATA from the database -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories; ELSEIF PaRactioncode = 2 THEN -- Retrive all from the database By ID -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories WHERE CatID=PaRCatID; ELSEIF PaRactioncode = 3 THEN -- NOSET YET -- INSERT INTO tmp SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tbcategories WHERE Published=1 ORDER BY DisplayOrder; END IF; IF PaRSearchText IS NOT NULL THEN set PaRSearchText=concat('%', PaRSearchText ,'%'); SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tmp WHERE Concat(CatTitle, CatDescription, CatTitleAr, CatDescriptionAr) LIKE PaRSearchText; ELSE SELECT CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,PictureID,Published,DisplayOrder,CreatedOn FROM tmp; END IF; DROP TEMPORARY TABLE IF EXISTS tmp; END

  • New Oracles VM RAC template with support for oracle vm 3 built-in

    - by wcoekaer
    The RAC team did it again (thanks Saar!) - another awesome set of Oracle VM templates published and uploaded to My Oracle Support. You can find the main page here. What's special about the latest version of DeployCluster is that it integrates tightly with Oracle VM 3 manager. It basically is an Oracle VM frontend that helps start VMs, pass arguments down automatically and there is absolutely no need to log into the Oracle VM servers or the guests. Once it completes, you have an entire Oracle RAC database setup ready to go. Here's a short summary of the steps : Set up an Oracle VM 3 server pool Download the Oracle VM RAC template from oracle.com Import the template into Oracle VM using Oracle VM Manager repository - import Create a public and private network in Oracle VM Manager in the network tab Configure the template with the right public and private virtual networks Create a set of shared disks (physical or virtual) to assign to the VMs you want to create (for ASM/at least 5) Clone a set of VMs from the template (as many RAC nodes as you plan to configure) With Oracle VM 3.1 you can clone with a number so one clone command for, say 8 VMs is easy. Assign the shared devices/disks to the cloned VMs Create a netconfig.ini file on your manager node or a client where you plan to run DeployCluster This little text file just contains the IP addresses, hostnames etc for your cluster. It is a very simple small textfile. Run deploycluster.py with the VM names as argument Done. At this point, the tool will connect to Oracle VM Manager, start the VMs and configure each one, Configure the OS (Oracle Linux) Configure the disks with ASM Configure the clusterware (CRS) Configure ASM Create database instances on each node. Now you are ready to log in, and use your x node database cluster. x No need to download various products from various websites, click on trial licenses for the OS, go to a Virtual Machine store with sample and test versions only - this is production ready and supported. Software.

  • Developing for 2005 using VS2008!

    - by Vincent Grondin
    I joined a fairly large project recently and it has a particularity… Once finished, everything has to be sent to the client under VS2005 using VB.Net and can target either framework 2.0 or 3.0… A long time ago, the decision to use VS2008 and to target framework 3.0 was taken but people knew they would need to establish a few rules to ensure that each dev would use VS2008 as if it was VS2005… Why is that so? Well simply because the compiler in VS2005 is different from the compiler inside VS2008…  I thought it might be a good idea to note the things that you cannot use in VS2008 if you plan on going back to VS2005. Who knows, this might save someone the headache of going over all their code to fix errors… -        Do not use LinQ keywords (from, in, select, orderby…).   -        Do not use LinQ standard operators under the form of extension methods.   -        Do not use type inference (in VB.Net you can switch it OFF in each project properties). o   This means you cannot use XML Literals.   -        Do not use nullable types under the following declarative form:    Dim myInt as Integer? But using:   Dim myInt as Nullable(Of Integer)     is perfectly fine.   -        Do not test nullable types with     Is Nothing    use    myInt.HasValue     instead.   -        Do not use Lambda expressions (there is no Lambda statements in VB9) so you cannot use the keyword “Function”.   -        Pay attention not to use relaxed delegates because this one is easy to miss in VS2008   -        Do not use Object Initializers   -        Do not use the “ternary If operator” … not the IIf method but this one     If(confition, truepart, falsepart).   As a side note, I talked about not using LinQ keyword nor the extension methods but, this doesn’t mean not to use LinQ in this scenario. LinQ is perfectly accessible from inside VS2005. All you need to do is reference System.Core, use namespace System.Linq and use class “Enumerable” as a helper class… This is one of the many classes containing various methods that VS2008 sees as extensions. The trick is you can use them too! Simply remember that the first parameter of the method is the object you want to query on and then pass in the other parameters needed… That’s pretty much all I see but I could have missed a few… If you know other things that are specific to the VS2008 compiler and which do not work under VS2005, feel free to leave a comment and I’ll modify my list accordingly (and notify our team here…) ! Happy coding all!

  • Difference between the terms Material & Effect

    - by codey
    I'm making an effect system right now (I think, because it may be a material system... or both!). The effects system follows the common (e.g. COLLADA, DirectX) effect framework abstraction of Effects have Techniques, Techniques have Passes, Passes have States & Shader Programs. An effect, according to COLLADA, defines the equations necessary for the visual appearance of geometry and screen-space image processing. Keeping with the abstraction, effects contain techniques. Each effect can contain one or many techniques (i.e. ways to generate the effect), each of which describes a different method for rendering that effect. The technique could be relate to quality (e.g. high precision, high LOD, etc.), or in-game-situation (e.g. night/day, power-up-mode, etc.). Techniques hold a description of the textures, samplers, shaders, parameters, & passes necessary for rendering this effect using one method. Some algorithms require several passes to render the effect. Pipeline descriptions are broken into an ordered collection of Pass objects. A pass provides a static declaration of all the render states, shaders, & settings for "one rendering pipeline" (i.e. one pass). Meshes usually contain a series of materials that define the model. According to the COLLADA spec (again), a material instantiates an effect, fills its parameters with values, & selects a technique. But I see material defined differently in other places, such as just the Lambert, Blinn, Phong "material types/shaded surfaces", or as Metal, Plastic, Wood, etc. In game dev forums, people often talk about implementing a "material/effect system". Is the material not an instance of an effect? Ergo, if I had effect objects, stored in a collection, & each effect instance object with there own parameter setting, then there is no need for the concept of a material... Or am I interpreting it wrong? Please help by contributing your interpretations as I want to be clear on a distinction (if any), & don't want to miss out on the concept of a material if it should be implemented to follow the abstraction of the DirectX FX framework & COLLADA definitions closely.

  • Fan not detected by lm-sensors

    - by OrangeTux
    My fan is blowing hard, while my cpu temperature is 32 degrees I tried a lot of things to control my fan. Changed grub file GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi= pci=noacpi" _ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=\"Linux\"" Ran sensors-detect : To load everything that is needed, add this to /etc/modules: #----cut here---- # Chip drivers coretemp #----cut here---- If you have some drivers built into your kernel, the list above will contain too many modules. Skip the appropriate ones! Do you want to add these lines automatically to /etc/modules? (yes/NO) Unloading i2c-dev... OK Unloading i2c-i801... OK Unloading cpuid... OK Ran sensors: acpitz-virtual-0 Adapter: Virtual device temp1: +34.0°C (crit = +90.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +34.0°C (high = +80.0°C, crit = +90.0°C) Core 2: +34.0°C (high = +80.0°C, crit = +90.0°C) Ran sudo start module-init-tools and sudo start module-init-tools module-init-tools stop/waiting As you can see my fan isn't detected. Running fancontrol gives me this: Loading configuration from /etc/fancontrol ... Error: Can't read configuration file Can you help me, please? I cannot use my laptop now in class. Thanks in advance.
