• Composer support

  - by Tomas Mysik

  Hi all, today we would like to introduce you our Composer support which will be present in NetBeans 7.3. If anyone of you does not know Composer yet, please be informed that: "Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you." So, what support do we have in NetBeans? The first step, as usually, is to open the Composer IDE Options panel: Once it is configured properly, it is time to create composer.json file where we can define dependencies (libraries) of our PHP project: The generated file is opened so we can review it and add any libraries:  Now, you are ready to install, update or validate library dependencies of your PHP project: We hope that you enjoy this initial support and that we will be able to improve it in the next version of NetBeans.    That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans Bugzilla (component php, subcomponent Composer).

• Now that Apple's intending to deprecate Java on OS X, what language should I focus on?

  - by Smalltown2000

  After getting shot down on SO, I'll try this here: I'm sure you'll all know of Apple's recent announcement to deprecate Java on OS X (such as discussed here). I've recently come back to programming in the last year or so since I originally learnt on ye olde BASIC many years ago. I have a Mac at home and a PC at work and whilst I have got Windows and Ubuntu installed on my Mac as VMs, I chose to focus my "relearning" on VB first (as it was closest to BASIC) and then rapidly moved to Java as it was cross platform (with minimal effort) and so it was easiest to work on code from both OSes. So my question, if the winds of change on Mac are blowing away from Java and in this post-Sun era, what would be the best language to focus my new efforts on? Please note, this isn't a general "which language is better?" thread and or an opportunity for the associated flame-war. There's plenty of those and it's not the point. I realise that in the long term one shouldn't be allegiant to an individual language so, taking this as an excuse, the question is specifically which is going to be the most quick to be productive on given the background whilst bearing in mind minimum portability rewrites (aspiration rather then requirement) and with a long term value of usage. To that I see the main options as: C# - Closest in "style" to Java but M$ dependent (unless you consider Mono of course) C++ - Hugely complex but if even slightly conquered, then a win? Is it worth the climb up the learning curve? VB.Net - Already have background so easiest to go back to but who uses VB for .Net these days? Surely if using a CLI language I should use C#... Python - Cross-platform but what about UI for the end-user? EDIT: As a usage priority, I envision desktop application programming. Though the ability to branch in the future is always desirable. I guess graphics are the next direction once basics are in place.

• Why doesn't my cron.d per minute job run?

  - by Travis Griggs

  I have thrown a bunch of darts trying to get a python script of mine to execute every minute. So I thought I'd simplify it to just do the "simplest thing that could could possibly work" once per minute (I'm running debian/testing). I created a single line file in /etc/cron.d/perminute: * * * * * /bin/touch /home/me/ding_dong It's owned by root, and executable (not sure if either of those matter). And then I did: sudo service cron reload And then sit back and start running ls -ltr again and again in my home directory (/home/me). But my ding_dong file never shows up. I know if I do a sudo /bin/touch /home/me/ding_dong, it shows up right away. Obviously missing something stupid here.

• Video streaming over multi display units

  - by ramdaz

  We have to share video across around 4/8 terminals at a public facility where we need to display live video from within the facility, as well as display messages(advertisements), and also play videos(not live) which need to be controlled centrally from another location. We can do central location handling over Internet, over ssh. What we want to do is connect cameras to a computer, and use the computer to display over multiple display units. We need to do live titling if possible. Once the live local telecast which usually takes about an hour or two a day, we would like to play other videos locally off the PC server. Preferably everything should run off Linux, since budgets are very constrained.... Addendum -- Its not over WAN, it's over a local area. I prefer not using LAN, we would rather use co-axial cable if possible. The reason is if it's LAN, I need some kind of an Networking device, at least a thin client

• Creating image of NTFS partition in Ubuntu

  - by Pappai

  Hi, I have a system that has to be formatted often because of the specific use of it (Use it in internet cafe). I have to install the drivers and apps each time. That is a time consuming and cumbersom task for me. I want to install windows, drivers, apps etc. once and create a backup of the entire C:\ drive, and keep it in a linux partition so that I can restore the OS with all the apps & drivers ready to go! I have ubuntu live CD with me and I have created a linux partition (ext4) in the HDD. My question is: How can I create an image of the C:\ drive (ntfs disk) in Ubuntu and store it in the linux partition?

• How do I get openssh to save my ssh identity permanently in Xfce?

  - by Alliswell

  How do I change it to save my identity permanently using Xfce? During my login session after I have entered: $ ssh-add Then identity is saved and I can connect via ssh without getting the dreaded: Enter passphrase for key However, once I logout and login back-in I get the following when running: $ ssh-add -L The agent has no identities. $ ssh <hostname> Enter passphrase for key '/home/user/.ssh/id_rsa': Stackoverflow has the following solution, yet I do not understand the reference to in the config file: IdentityFile ~/.ssh/id_rsa_buhlServer Specifically I do not understand what I would put on the identity file. Would I put the above word for word? Or just add my file: IdentityFile ~/.ssh/id_rsa StackOverflow solution

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Screen refresh/display problem in Xubuntu 14.04

  - by user286328

  I have just installed Xubuntu 14.04 as a dual boot on a desk top (Pentium R 4 CPU, 2.66 GHZ, 2G RAM) running XP home edition. In some situations when in Xubuntu I am having what seem to be screen refresh problems. When I open File Manager or Settings Manager the text names of various apps display but most of the icons do not. Moving the mouse over an app name generally causes the icon to appear, but it often vanishes once the mouse pointer is moved. This issue occurs irrespective of the view setting. Icons appear fine in the menu that comes up when I right click in the desktop, and in the menu that comes up when I click the mouse icon at top left. What I suspect is a related issue. In Abiword text sometimes fades, disappears or does not display immediately when I type, or text of the whole document fades. It then comes back or darkens if I left click a few times on the text. If I scroll through a document the text often fades and may remain faded until I left click a few times.

• Is PO Box on resume to get a call okay?

  - by sanksjaya

  Hello folks! Personally I've applied to quiet a handful of IT admin jobs inside my state and to the ones that are way far away. The sad part is I never miss to get an interview with the jobs in my state, but get a call once in a blue moon from jobs out of my state. Note: All the jobs are of similar nature. Recently one of my friends told me that "Applicants with local addresses are the ones that are even looked upon". How true is this? Does filtering take place at address level before qualifications? Is using a PO box on resume acceptable [one for each state like CA, TX, VA]? Any other suggestions to get calls from out of state? Thank you :) [wiki]

• Commercial template (theme) sellers which give license to resell the template?

  - by Tony_Henrich

  I came once across a website template seller which granted rights to resell the template to the buyer but forgot to bookmark it. All the commercial template vendors I know of (Template Monster, BoxedArt, Dreamtemplate..etc) don't allow this. Anyone knows of any sellers which allow this? Some of them allow you to resell the template if it's packaged for a different host software. For example, if I buy a website template, I am allowed to sell it as a WordPress or Joomla or Drupal theme. I am aware of public domain and free templates sites but I am not looking for those. I am talking about templates which are being sold.

• Dual-boot more than two operating systems

  - by aldorado

  I currently run Windows 7 and Ubuntu 12.04 as a dual-boot system. I need Linux, but Ubuntu freezes at least once a day. So I want to replace it with another distribution like Debian or LMDE. On the other hand I am a little concerned that I'll have troubles working with a less user friendly operating system than Ubuntu. So would it be possible to just scale down the Windows partition and install the next Linux as a third system? Thus, with a "triple-boot system" I could keep Ubuntu until I feel familiar with the new system. Afterwards, I guess, it should be possible to replace the Ubuntu partition by expanding the new system?

• getting started automating virtualization with powershell on windows

  - by fschwiet

  What are some good books or resources for learning automate virtual PCs on Windows DataCenter? I want to be able to build VPCs with both automated installs and from images, preferably via powershell. I would like to be able to setup an IIS environment for automated testing, and configure end user installs of different versions of Windows. I am not interested in corpnet type scenarios (active directory, domains, etc) so much for now. I'm comfortable with powershell and programming in general. I haven't yet installed Windows DataCenter, maybe once I install it will be clear enough. But looking for resources on how to managed virtual PCs programmatically I haven't found anything.

• set a global environment variable in linux that sticks when going root

  - by Scott

  When I SSH into a linux box, I want to have the /etc/profile file save the results of the whoami command to a global environment variable. if I were to go root with the command sudo su -, I do not want that command to run again when gonig root, I want it to stick with the result of whoami as my regular username from before I went root, and I need to access that variable as the root user even though it will run the /etc/profile file again when I go root. What can I do to only run that command once in the /etc/profile command?

• There's Not an App for That (Yet)

  - by Mark Hesse

  With an earlier-than-normal departure this morning to avoid the stalemate known as traffic congestion, I suddenly realized what I had failed to grab on my way out the door...  my company ID badge.  Unfortunately, at the time of my epiphany, I was far enough into commuter no-man's land where turning back would completely negate my early departure and increase my overall drive time exponentially.  Not being one to retrace my steps, I decided to press on. Upon arrival at the office and with an hour to go before a security guard would be on duty, I started thinking about the number of times I had forgotten my ID vs. the number of times I had forgotten my phone.  While rare on both accounts, my ID was most likely the missing artifact. I then wondered why there isn't an app for my smartphone that allows me to verify my credentials with my employer and then, provided with a secure token for the day, have the ability to access my building's card entry system.  On many levels, this seems much more secure than an ID card which can be lost, stolen or even forged and then used simply by tailgating into and around buildings at facilities where card scanning can generally be avoided.   As it turns out, another building on the campus has 24 x 7 guard coverage, so I was able to gain access in a relatively short time and secure a temporary ID badge.  Once inside and online, a quick internet search on the subject of smartphone badge access shows that efforts are underway to do exactly what I was thinking needed to be done. Having not spent any time studying about the technology, I discovered that it relies on Near Field Communications (NFC) enabled smartphones (of which, mine does not provide).  The only other option would require modifications to the security infrastructure to support alternative authentication technologies, such as barcode readers, which would be extremely costly to implement. For now, my best option is to put my corporate ID under my car keys...

• Farseer Physics Samples and Krypton how to reference game

  - by Krell

  I'm sure this is totally simple and yes I am new at this. I am trying to set up Krypton inside farseer. 1. create a new Krypton engine in my sub screen aka AdvancedDemo1 : PhysicsGameScreen, IDemoScreen Via this.krypton = new KryptonEngine(this, "KryptonEffect"); The problem is the KryptonEngine(this wants reference to Game game, I cant seem to reference it from FarseerPhysicsGame : Game So how would I do that? or 2. I can put it directly in FarsserPhysicsGame but again I cant seem to figure out how to reference FarseerPhysicsGame in AdvancedDemo1. or 3. I can put it inside the public FarseerPhysicsGame() and do Componenets.Add(krypton) [which works] HOWEVER I cant figure out how to reference the compoenet once it is added. You should be able to stop reading here , but for more detail I simply took the Farseer XNA Samples went into FarseerPhysicsGame.cs and deleted all the screens and menus except AdvancedDemo1 so there is one option and I just click that to load into the advancedDemo1 and thats where I want to put the lights from krypton. Thanks. Edit: Figured out 1 solution though I am still curious about others. Solution 1 I was able to use ScreenManager.Game(not sure why it was there but Ill try to figure it out later)

• Forensics on Virtual Private servers [closed]

  - by intiha

  So these days with talks about having hacked machines being used for malware spreading and botnet C&C, the one issue that is not clear to me is what do the law enforcement agencies do once they have identified a server as being a source or controller of attack/APT and that server is a VPS on my cluster/datacenter? Do they take away the entire machine? This option seems to have a lot of collateral damage associated with it, so I am not sure what happens and what are the best practices for system admins for helping law enforcement with its job while keeping our jobs!

• Minimizing use of paper

  - by Abody97

  I've recently faced this problem in a dynamic programming curriculum, and I honestly have no idea about how to determine the appropriate state. You're given N (1 <= N <= 70) paragraphs and M (1 <= M <= N) figures. Each paragraph i requires PL_i (1 <= PL_i <= 100) lines and references at most one figure. Each figure is referenced exactly once (i.e., no two paragraphs can reference the same figure, and for each figure there's a paragraph that references it.) Each figure requires PF_i (1 <= PF_i <= 100) lines. The task is to distribute those figures and paragraphs on paper in the order they're given, where one paper fits for L lines at most. No paragraph or figure is too large to fit on one paper. If a paragraph x placed on paper x_p references a figure y then y must be placed on either the paper x_p - 1 or x_p or x_p + 1. We have to find the minimum number of lines (and thus pages) to allocate in order to distribute all the figures and paragraphs. Any help would be extremely appreciated. Thanks in advance!

• /manual/cache folder on my server?

  - by MrZombie

  Hi all, On our site's server, once managed by someone who's no longer with us, there's a folder named "/manual/cache" which contains txt files named+like+this, mostly using pornographic-related keywords. The content is mainly spam-like gibberish. My assumption on the matter is that it's somehow used to spam search engines, but I might be wrong, which is the reason of my question here. Any idea what it might mean/contain? As an additionnal note, the person's hiring period oddly correspond to the dates of the files, which seem to have automagically stopped being generated after the date we parted ways.

• macports apache,php,db, how do I test on another device?

  - by brokenindexfinger

  My supervisor suggests using macports to install/manage different versions of apache and php, as well as both mysql and posgres databases. The idea is that we need to test our platform on different versions of each. So far I've just been using the default apache installation on osx lion, and the default postgres installation. My question is this: once I turn Web Sharing off, and proceed with a custom apache2 setup based in /opt/local/, how do I broadcast my machine's IP to other devices, for testing? With Web Sharing, I can get my machine's IP and use that to test with an iPad and iPhone. Will that still be the case, and if so, how do I do it?

• How can I speed up boot on one of my machines?

  - by Korneel Bouman

  I have a Gateway all in one machine (2 gig Intel Core 2 Duo T7250 dual core processor, 2 gig RAM - full specs) on which I installed 10.10. Once it has booted it's fine, but it takes forever to boot. This is what happens: 1. Boot starts with cursor flashing for about 10-15 seconds 2. Cursor disappears for 1.5 - 2 minutes 3. Cursor reappears, blinks a few seconds more, boot finishes in another 10 seconds 4. Login screen I have another machine with marginal better specs that boots up in no time (basically the above minus the two minute delay). Things I've done: enabled verbose mode for grub nothing is showing until after 2 minute pause. checked syslog last message before pause is a message from alsa saying the process is already running (or something similar... going from memory here...) It could be something sound related as the built in speakers are not working (sound card is recognized though and headphones work). Anyway, it's not the end of the world, but it's annoying and I'd like to know what's going on... Many thanks, and let me know if more info is needed.

• Can I install Ubuntu 13.10 without the internet?

  - by user1526570

  I'm new to Ubuntu and Linux in general. I'm currently out of town and the dorm I am living in has terrible internet connection. It won't be another 2-3 weeks before I can go home and have proper internet connection. So my question is whether or not I can install Ubuntu 13.10 in my laptop without the internet and then do the updates once I go home? Also, I'm attempting to do a dual boot with my Lenovo G505s which was pre-installed with Windows 8. Hopefully I can pull this off. I already did the necessary things (I think and hope so) prior to installation: Disable secure boot Enable legacy and boot UEFI first Create partition Put installer in my pen drive As I am quite new to this, any advice would be of great help. Thanks in advance! EDIT: I tried yesterday. The installation asked me to connect to the internet, so I used my crappy dorm internet. When it reached the downloading/installtion of Ubuntu One, it just stopped and went on forever. So I had to stop it.

• I use windows7 and am looking for a tool to help me tag/organize my bookmarks as well as my thoughts and projects.

  - by tomcat23

  I've got my bookmarks in Chrome currently, and am prone to just bookmarking something if it contains any info I may need for the project I'm currently working on. I had found a way to tag them with delicious and then get an export from that into a wordpress test server (with the tags), having a post for each bookmark, but this proved to be a bit of a waste of time, as there's no way to organize it well. Ideally I'd like to find some sort of mind-mapper with a Prezi-like view, that does auto tagging, excerpting and allows me to notate things effectively. Does my dream tool even exist? I've usually got 20+ tags open all at once because there may be something open on each I need to see/know to make my current project work. It's frustrating. Though I'm on Win7, I'm interested to hear about any tools that are out there that work to take your existing bookmarks and help you organize them productively.

• Limit a process's relative (not absolute) processor consumption in Linux

  - by BobBanana

  What is the standard way in Linux to enforce a system policy to limit the relative CPU use of a single process? That is, on a quad-core machine, I never want a process to use more than 2 CPUs at once, even if the process creates more threads. I do not want an absolute time limit, just a relative limit so that one task cannot dominate the machine. This is also different than renice, which allows a process to use all the resources but just politely step aside if others need them too. ulimit is the usual resource limiting tool, but it does not allow such CPU restrictions.. it can limit the number of processes per user, or absolute CPU time, not restrict the maximum number of active threads of a single process. I've found a couple of user-level tools, like CPUlimit, but not a system level tool or setting. Does such a standard resource controller exist in Linux (Red Hat Enterprise, if it matters.) If there is such a limit imposed, how would a user identify it?

• zune - how do i make the PC zune download a movie, not stream it?

  - by bharal

  As the title suggests - I have bought a tv show series season on PC Zune. My gf watched the show, and now i'd like to be able to watch the show too. The catch - i'm going to go overseas on a trip soon, and i'd like to be able to watch the show from outside the US. Given that Zune won't let me stream things overseas (past experience, anyway), I would like to download the show to my computer and watch it that way. The problem is that although the full season has been "watched" it appears it was only streamed, not downloaded. Or rather, that one episode was downloaded, and the rest streamed. I bought a season pass (so all the episodes at once) and the show was bought, not rented. How do i make Zune download, not stream, a show?
