• Highlight identical strings in vi(m)

  - by Boldewyn

  One feature of Notepad++, which I find really useful and haven't found elsewhere, is the highlighting of other text that is identical to the one currently selected. Is there something similar possible with vi(m)? (Of course, there is. But how do I achieve it?) That is, any of those: If I am in Visual Mode and have text selected: Highlight identical text If I have searched /foo, highlight all instances of foo. If I am at the beginning of a string (series of characters, numbers or underscores), highlight all other matching strings (prefered solution). The last one is similar to the closing parentheses matching and IMHO the most useful. Edit: For my second use case, I found a solution (that is, Google found it...): :set hls However, the others remain.

• TechEd 2012: Fast SQL Server

  - by Tim Murphy

  While I spend a certain amount of my time creating databases (coding around SQL Server and setup a server when I have to) it isn’t my bread and butter.  Since I have run into a number of time that SQL Server needed to be tuned I figured I would step out of my comfort zone and see what I can learn. Brent Ozar packed a mountain of information into his session on making SQL Server faster.  I’m not sure how he found time to hit all of his points since he was allowing the audience abuse him on Twitter instead of asking questions, but he managed it.  I also questioned his sanity since he appeared to be using a fruit laptop. He had my attention though when he stated that he had given up on telling people to not use “select *”. He posited that it could be fixed with hardware by caching the data in memory.  He continued by cautioning that having too many indexes could defeat this approach.  His logic was sound if not always practical, but it was a good place to start when determining the trade-offs you need to balance.  He was moving pretty fast, but I believe he was prescribing this solution predominately for OLTP database prior to moving on to data warehouse solutions. Much of the advice he gave for data warehouses is contained in the Microsoft Fast Track guidance so I won’t rehash it here.  To summarize the solution seems to be the proper balance memory, disk access speed and the speed of the pipes that get the data from storage to the CPU.  It appears to be sound guidance and the session gave enough information that going forward we should be able to find the details needed easily.  Just what the doctor ordered. del.icio.us Tags: SQL Server,TechEd,TechEd 2012,Database,Performance Tuning

• DB Object passing between classes singleton, static or other?

  - by Stephen

  So I'm designing a reporting system at work it's my first project written OOP and I'm stuck on the design choice for the DB class. Obviously I only want to create one instance of the DB class per-session/user and then pass it to each of the classes that need it. What I don't know it what's best practice for implementing this. Currently I have code like the following:- class db { private $user = 'USER'; private $pass = 'PASS'; private $tables = array( 'user','report', 'etc...'); function __construct(){ //SET UP CONNECTION AND TABLES } }; class report{ function __construct ($params = array(), $db, $user) { //Error checking/handling trimed //$db is the database object we created $this->db = $db; //$this->user is the user object for the logged in user $this->user = $user; $this->reportCreate(); } public function setPermission($permissionId = 1) { //Note the $this->db is this the best practise solution? $this->db->permission->find($permissionId) //Note the $this->user is this the best practise solution? $this->user->checkPermission(1) $data=array(); $this->db->reportpermission->insert($data) } };//end report I've been reading about using static classes and have just come across Singletons (though these appear to be passé already?) so what's current best practice for doing this?

• Canon MP280 All in One prints but scanner not recognized

  - by Chris

  I recently installed Ubuntu 12.04 LTS after not using any Linux distro for several years. My Canon MP280 worked perfectly as far as printing goes and I was even able to set it up on a Samba share and print from a Windows 7 machine. However when I open Simple Scan it does not detect a scanner. I did find some instructions online but the scanner is still not recognized in Simple Scan even after installing a couple .deb packages from the Canon site. I also couldn't seem to find the ScanGear package after installing those .deb packages as well but I haven't had a chance to delve fully into it. Thanks for your time!

• Getting error message when trying to start a virtual machine

  - by Sunil J

  I have been using VMWare on Windows for a long time. But after a long wait, I moved to VirtualBox on Ubuntu 11.10. I installed Ubuntu, 32 Bit, installed all available updates and installed Virtual Box. When I try to create a new Windows installation inside VirtualBox, I got the following error messages. 1st error dialogue VirtualBox - Error Failed to open a session for the virtual machine Windows XP.<br> The virtual machine '**Windows XP**' has terminated unexpectedly during startup with exit code 1.<p> Details<p> Result Code: <br> NS_ERROR_FAILURE (0x80004005)<br> Component: <br> Machine<br> Interface: <br> IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}<p> 2nd error dialogue **Virtualbox - Error in suplibOsinit**<br> **Kernal driver not installed (rc--1908)**<br> Please install the virtualbox-dkmbs package and execute 'modprobe vboxdrv' as root.<p> Steps I tried I have already tried reinstalling VirtualBox. Google result seem to indicate the the problem happens due to Kernel updates. Is there anyway I can get this working? I need this for malware analysis and if VirtualBox is going to crash on me all the time, then I won't be able to use Ubuntu for work.

• Which is better? Native App or hybrid App?

  - by Prabakaran

  I want to develop a simple App for iOS, Android and windows phone. I just wondered that a simple HTML5, JS and CSS combination can work in all of these platforms. I want to know which one will be efficient? No problem with time and coding. But if i can achieve everything with HTML5-JS itself, i will chose Hybrid development. I want to know the major difference between the Native and Hybrid Development with example(I know that the main difference is HTML5-JS supports cross platform). Note : I am not making a game app.

• Simplicity-effecincy tradeoff

  - by sarepta

  The CTO called to inform me of a new project and in the process told me that my code is weird. He explained that my colleagues find it difficult to understand due to the overly complex, often new concepts and technologies used, which they are not familiar with. He asked me to maintain a simple code base and to think of the others that will inherit my changes. I've put considerable time into mastering LINQ and thread-safe coding. However, others don't seem to care nor are impressed by anything other than their paycheck. Do I have to keep it simple (stupid), just because others are not familiar with best practices and efficient coding? Or should I continue to do what I find best and write code my way?

• How to nmot show any prompts when inserting a USB drive in Windows?

  - by jasondavis

  1) I just found a really interesting program that allows me to use a USB drive as a windows login key. It is called Rohos Logon Key. IF I remobve my USB drive/key from the PC then I can have the PC lock or hibernate or any other option, I have been looking for such a solution for many years but never knew one existed until this and it works much better then I imagined. I do have a couple minor issues though (im using Windows 7 pro). When I remove and then re-insert my USB key, windows prompts me with this dialog here... Generally when I get this I just click on "Continue without scanning" however I am looking for a solution to just make it not even show this at all, is it possible to disable it from showing? 2) I also get this dialog as well when I insert USB drives/key... Would it be possible to not show this as well or have it pick an option by default or anything really?

• MySQL cluster: 20Tb x 3K tables

  - by ethrbunny

  Over the next 2-3 years we will be scaling up data collection for a project. As a result the amount of data will grow 10-fold. Our current MySQL installation can keep up with the 2Tb of data but for larger queries there is a fair amount of IOWait. Im investigating a migration to a clustered solution to spread out the IO but am wondering about NDB and what happens to data that doesn't get accessed very often. The impression I get from reading about MySQL cluster is that it relies on memory tables for most of the data. What happens with tables that don't get accessed very often (or at all)? And how does backup work? Can I use MYSQLDUMP or is there a better solution?

• I believe I need a wireless access point, but can I do it with a wifi router?

  - by Flotsam N. Jetsam

  My needs are simple, I think: I have a laptop upstairs with a usb wifi that I use to connect to my neighbor's wifi which I share (with their knowledge). I have a laser printer downstairs that my wife doesn't wants to stay down there (big, bulky and ugly), but that we both need to print stuff off. It has wired networking and I have wired hub and router down there. The usb wifi on the laptop has absolutley the best reception I've ever seen or heard of. I cannot get onto the neighbor's net with the thing downstairs though--sortof in the ground. What do I need downstairs to give printer access to my laptop wirelessly? One thing I can't do in this solution is have a computer on downstairs, so I would think that would eliminate a usb solution.

• What command are my volume keys running?

  - by user2787904

  In Unity I use my ThinkPad hot keys to change the volume. I need to know the command that these keys run so that I can bind it in my window manager. I have tried using amixer but could not change the volume through command line amixer set Master 10%- amixer: Unable to find simple control 'Master',0 amixer scontrols: Simple mixer control 'IEC958',0 amixer set 'IEC958' 50%- amixer: Invalid command! So obviously this is not what Unity is running. I have tried changing the default sound card as well but that didn't help.

• Workaround for API limits [closed]

  - by blunders

  Problem: Planning on building out a client services company that requires access to APIs. Most APIs are limited based on user, IP, etc. - and even though the API calls would be on a per client basis, there's no way to get usage not tied to IPs. (Theoretical) Solution: Have each client install on their network a proxy/VPN that would allow my systems to connect and use their assigned usage. So, it's possible there's a better solution than the one I've thought of, but it's the only one I've been able to come up with.

• Automate Win8 network and sharing settings

  I am trying to create a unattended DVD installation of Windows 8, but I can't seem to find a solution do this. What I'm looking for are to have the same settings on the Network and Sharing Center, to have the Turn on network discovery "on" for both the private and guest/public within the Control Panel. For private and guest/public, I need to: Turn on network discovery Turn on printer and file sharing Turn off public folder sharing Turn on password protected sharing Use user accounts and passwords to connect to other computers I've been searching for days and have not found a solution yet.

• Algorithm to generate N random numbers between A and B which sum up to X

  - by Shaamaan

  This problem seemed like something which should be solvable with but a few lines of code. Unfortunately, once I actually started to write the thing, I've realized it's not as simple as it sounds. What I need is a set of X random numbers, each of which is between A and B and they all add up to X. The exact variables for the problem I'm facing seem to be even simpler: I need 5 numbers, between -1 and 1 (note: these are decimal numbers), which add up to 1. My initial "few lines of code, should be easy" approach was to randomize 4 numbers between -1 and 1 (which is simple enough), and then make the last one 1-(sum of previous numbers). This quickly proved wrong, as the last number could just as well be larger than 1 or smaller than -1. What would be the best way to approach this problem? PS. Just for reference: I'm using C#, but I don't think it matters. I'm actually having trouble creating a good enough solution for the problem in my head.

• Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?

  - by Andy Harglesis

  I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however. 2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up: 1.When the pixels touch; 2.when a rectangle range is exceeded; 3.when a pixel object is detected near another one in a pixel-based rendering engine. But 3-D is different with one dimension, but complex in many more so ... what are the general, basic understanding/examples on how 3-D collision detection can be implemented? Think two shaded, OpenGL cubes that are moved next to each other with a simple OpenGL rendering context and keyboard events.

• why only google related sites load using wireless network

  - by gansai

  I have a wireless internet connection through BSNL. I have a windows 7 ultimate, and using latest Google chrome. During night time ie from 12:30 am onwards till around 5:30 am, I have the following problem: Only the following webpages load: Google Search Google images and all related to google product pages like you see them on the google home page. Blogspot webpages as supported through Google. Any other site loading gets stuck with the status message:- Waiting for www.thaturl.com .... And it goes on and on. Why does this happen? I checked around googling for this but no solution at all. By the way I tried changing my dns addresses too sometimes from automatically to opendns and then Google public dns. I need some solution which might help me to load other websites also. Thanks in advance.

• Raid-3 like software backup tool

  - by Chronial

  I have a lot of data (about 7 TB), stored across multiple hard-drives with varying sizes. I would like to have a backup of that data to be safe against drive failure. A RAID is not a good option for me, as I want to keep my cost low and be able to easily extend the storage capacity of my setup by buying an additional HD. I remember seeing a piece of software that generates parity data over all drives and stores that on an extra drive. That solution protects the setup from hard drive failure and works with varying drive sizes (as long as the parity drive is the biggest one). But I can’t seem to find that software again. Does anybody now what I’m talking about or have any other solution for my situation?

• How to copy and paste code with retaining the format

  - by Sab

  This question may have been asked before but I was unable to find any solution. So here goes: When I browse and see some code that I would like to copy I simply use ctrl+c and ctrl+v. Most of the time this works fine. But in some cases (websites like stackoverflow and others ) when I copy the code and paste it , it only comes on one line in eclipse. I have tried pasting this code into eclipse and select all and hitting auto format but this doesnt help either. I have also pasted the code into komodo and word. But to no avail. The code simply refuses to align itself. Does anyone know any solution to this?

• Efficient algorithm for Virtual Machine(VM) Consolidation in Cloud

  - by devansh dalal

  PROBLEM: We have N physical machines(PMs) each with ram Ri, cpu Ci and a set of currently scheduled VMs each with ram requirement ri and ci respectively Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram ri. A PM with no VMs is shut down to save power. Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations. My Approach: Brute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by First Fit Decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I used the links. http://dumas.ccsd.cnrs.fr/docs/00/72/52/15/PDF/Esnault.pdf http://hal.archives-ouvertes.fr/docs/00/72/38/56/PDF/RR-8032.pdf Would anyone please clarify the solution or suggest any new approach/resources for better performance. I am basically searching for the algorithms not the physical optimizations and I also know that many commercial organizations have provided these solution but I just wanted to know more the underlying algorithms. Thanks in advance.

• How to run a command in a process that is not a child of the current process?

  - by amicitas

  I am having a library conflict issue with calling an external program from within a interpreted programming environment (IDL). The issue seems to be that since the program I am calling ends up as a child of IDL, libraries are not being reloaded. From within IDL I can launch sub-processes either directly or using a shell. Is there a good way that I can cause my program to be run without ending up as a child process? The only solution I have found so far is to use ssh localhost my_program. This works perfectly but I would like a more direct solution.
