• Intel Rapid Start Driver Reinstallation doesn't work?

  - by elegantonyx

  I recently had to reformat my entire drive and reinstall Windows 7. Something that bothers me is that when I was downloading the Intel Rapid Start driver (I have a Lenovo Ideapad Y480, and it comes standard with the Rapid Start) and tried to install it, the installer claimed that my system did not meet the requirements in order to install, when it was previously installed by the OEM. My startup times have increased from 21 seconds to log-in screen to 50 seconds. Please help... Specs: Lenovo Ideapad Y480 Intel Core i7-3610 Ivy Bridge (quad-core) Nvidia Geforce 640M LE with 2gb VRAM 8GB RAM 1TB hard drive, 32 GB SSD (OEM installed)

• Enabling Attachments in Oracle Forms

  - by Manoj Madhusoodanan

  In this blog I will demonstrate how we can enable attachments in Oracle Form. The user ask is to capture a job description which will be along text. Oracle Apps has a feature called attachments, through some easy setup we can enable attachments in forms. We will be going to addresscustomer ask through this feature. Step 1 : Identify Form Name First thing you have to do is to identify the form to enable attachment. In this scenario form will be PERWSDJT ( Job form in HRMS ). Step 2 :  Identify Document Entity exists or not. If exists then do nothing otherwise create new. Step 3 : Create Document Categories. Here I will create a category Job Description with Default Data Type Long Text and Application Human Resources.Onceit is done I will assign this to Create Job form. Step: 3 Query Attachment Functions for PERWSDJT. Click on Categories and add Job Description.Make sure enabled check box is checked. v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Step 4 : Turn off HR:Use Standard Attachments profile option.

• how to create java zip archives with a max file size limit [closed]

  - by Marci Casvan

  I need to write an algorithm in java (for an android app) to read a folder containing more folders and each of those containing images and audio files so the structure is this: mainDir/subfolders/myFile1.jpg It must be in java, something like perl script is not an option. It would preferably be for the compressed archive in order to squeeze as many files as possible before mailing the zip. Just a normal zip (no jar). My problem is that I need to limit the size of the archive to 16mb and at runtime, create as many archives as needed to contain all my files from my main mainDir folder. I tried several examples from the net, I read the java documentation, but I can't manage to understand and put it all together the way I need it. Has someone done this before or has a link or an example for me? I resolved the reading of the files with a recursive method but I can't write the logic for the zip creation I'm open for suggestions or better, a working example. EDIT: FileNotFoundException (no such file or directory) this was my initial post at Stack Overflow. I've got an answer to it, but I can't set the size of the ZipEntry and the logic doesn't work and also when extracting the my files from the zip I get the compression method not supported error.

• Sorting out mSSD acceleration on a Acer M3-581TG

  - by PhonicUK

  I recently purchased a Acer Timeline M3 Ultra, it ships with a 500GB HDD and a 20GB mSSD to use as a cache. First thing I did when I got it was format the drives and install a clean OS (on the HDD, the mSSD has nothing on it) - but now I can't figure out how everything needs to be configured in order to use the mSSD as a cache, it just looks like a standard storage drive. I've poked around in the BIOS and there is a SATA mode setting, but it only has one option (AHCI), most of the documentation I've seen on the subject says that the SATA controller needs to be in RAID mode otherwise 'Acceleration' isn't visible in the Intel SRT menu (which for me, it isn't) I've seen a few things that suggest I just need the correct partition layout, I tried this using fdisk from a Linux LiveCD but got nowhere. Any ideas? The laptop shipped with no recovery media so I'm marginally stumped. I don't have any issue with reformatting again if required.

• ACL mess after rsync on Windows 2008

  - by jdehaan

  The permissions in the ACL are not in the right order on some files and directories after having used rsync to synchronize directory trees. The stuff works well as it is on Windows 2003. Can someone explain this in detail. What exactly changed regarding ACLs from Windows 2003 to 2008? We fixed the rights with icalcs afterwards. But this thing seems a bit weird. Maybe 2008 has some restrictions or more checks 2003 did not have.

• Photo transfer problems from camera

  - by warkior

  We have a digital camera (Cannon SX130 IS) which we often connect to the Ubuntu 12.10 desktop via USB in order to download the images. In past flavours of Linux (Mint 12 was most recent) it worked fine, however since upgrading to Ubuntu 12.10, the process fails after downloading a small number of the images. I can view the images which will be transferred in the preview window, and I can browse the camera file system to download the images manually, but if I just drag/drop the images over from camera to desktop, it freezes after 5-6 are copied over. I've been able to get around the problem by only copying 3-4 at a time, but when you have 100+ images to transfer, that gets really frustrating. Any advice on where I could start looking for answers, or how I could diagnose the source of the problem further? We have also had some issues with WireLess USB mice though it may not be related. I'm hoping my USB controller in the computer isn't dying... it's not that old. Also, it seems to work much better under Windows.

• Write and fprintf for file I/O

  - by Darryl Gove

  fprintf() does buffered I/O, where as write() does unbuffered I/O. So once the write() completes, the data is in the file, whereas, for fprintf() it may take a while for the file to get updated to reflect the output. This results in a significant performance difference - the write works at disk speed. The following is a program to test this: #include <fcntl.h #include <unistd.h #include <stdio.h #include <stdlib.h #include <errno.h #include <stdio.h #include <sys/time.h #include <sys/types.h #include <sys/stat.h static double s_time; void starttime() { s_time=1.0*gethrtime(); } void endtime(long its) { double e_time=1.0*gethrtime(); printf("Time per iteration %5.2f MB/s\n", (1.0*its)/(e_time-s_time*1.0)*1000); s_time=1.0*gethrtime(); } #define SIZE 10*1024*1024 void test_write() { starttime(); int file = open("./test.dat",O_WRONLY|O_CREAT,S_IWGRP|S_IWOTH|S_IWUSR); for (int i=0; i<SIZE; i++) { write(file,"a",1); } close(file); endtime(SIZE); } void test_fprintf() { starttime(); FILE* file = fopen("./test.dat","w"); for (int i=0; i<SIZE; i++) { fprintf(file,"a"); } fclose(file); endtime(SIZE); } void test_flush() { starttime(); FILE* file = fopen("./test.dat","w"); for (int i=0; i<SIZE; i++) { fprintf(file,"a"); fflush(file); } fclose(file); endtime(SIZE); } int main() { test_write(); test_fprintf(); test_flush(); } Compiling and running I get 0.2MB/s for write() and 6MB/s for fprintf(). A large difference. There's three tests in this example, the third test uses fprintf() and fflush(). This is equivalent to write() both in performance and in functionality. Which leads to the suggestion that fprintf() (and other buffering I/O functions) are the fastest way of writing to files, and that fflush() should be used to enforce synchronisation of the file contents.

• A space-efficient guest filesystem for grow-as-needed virtual disks ?

  - by Steve Schnepp

  A common practice is to use non-preallocated virtual disks. Since they only grow as needed, it makes them perfect for fast backup, overallocation and creation speed. Since file systems are usually based on physical disks they have the tendency to use the whole area available1 in order to increase the speed2 or reliability3. I'm searching a filesystem that does the exact opposite : try to touch the minimum blocks need by an aggressive block reuse. I would happily trade some performance for space usage. There is already a similar question, but it is rather general. I have very specific goal : space-efficiency. 1. Like page caching uses all the free physical memory 2. Canonical example : online defragmentation 3. Canonical example : snapshotting

• Migration a database from 32bit to 64bit

  - by Mike Dietrich

  Database migrations from an 32bit environment to an 64bit environment keeping the same platform architecture (e.g. moving an Oracle 10.2.0.5 database from MS Windows XP 32bit to MS Windows Server 2003 64bit) does not happen that often anymore. But still we see them getting done. And there are a few things to note when doing such a move. First of all the important question is:Will you upgrade your database as part of this move - Yes or No? If you say "Yes" then you are almost done with that topic as we will take care of that bitnes move during the upgrade. The only thing you have to take care is OLAP in case you are using OLAP Option with Analytic Workspaces (AW) by yourself. Those store data in Binary LOBs - and in order to move AWs from 32bit to 64bit you have to export your AWs prior to the move - and import them later on. People who don't use OLAP don't have to take care on this. But if you say "No" (meaning: no upgrade actions involved - you keep your database version) then you have to make sure to invalidate all packages and stored code in the database before you shutdown your database in the 32bit environment and prior to moving it over. And the same rule as above for OLAP applies once you use the OLAP Option. In the source environment: startup upgrade;    -- [or startup migrate; -- for Oracle 9i] @?/rdbms/admin/utlirp.sqlshutdown immediate In the destination environment: startup upgrade @?/olap/admin/xumuts.plb --Only if OLAP Option is installed@?/rdbms/admin/utlrp.sql The script utlirp.sql will invalidate all packages and stored code, utlrp.sql will recompile - and xumuts.plb will rebuild the OLAP Analytic Workspaces in case you have the OLAP Option installed.

• How to dual OS 32-bit/64-bit Windows 7 Ultimate.

  - by Cyril Horad

  I have a problem with regards to my nVidia driver not running on 64-bit. I decided to install both 32-bit and 64-bit on my ASUS K42JC (4GB RAM upgrade) in order to function the nVidia on the 32-bit. My question is, how could I make my laptop run on either 32-bit or 64-bit OS. What options I am suppose to use, a single, double, or triple partition? From an answer: Well. When I installed the nVidia driver from either the ASUS site and the prescribed driver from NVIDA site via System Requirements Lab, both ended up freezing my laptop to the point when the desktop is about the finish booting. I have tried three(3) times reformatting and trying to fix the problem. Yet no use. I filed a ticket to the Asus support but for now no replies yet. But this bothers me, why wouldn't the nVidia run on 64bit yet it runs perfectly on 32bit.

• 3d Model Scaling With Camera

  - by spasarto

  I have a very simple 3D maze program that uses a first person camera to navigate the maze. I'm trying to scale the blocks that make up the maze walls and floor so the corridors seem more roomy to the camera. Every time I scale the model, the camera seems to scale with it, and the corridors always stay the same width. I've tried apply the scale to the model in the content pipe (setting the scale property of the model in the properties window in VS). I've also tried to apply the scale using Matrix.CreateScale(float) using the Scale-Rotate-Transform order with the same result. If I leave the camera speed the same, the camera moves slower, so I know it's traversing a larger distance, but the world doesn't look larger; the camera just seems slower. I'm not sure what part of the code to include since I don't know if it is an issue with my model, camera, or something else. Any hints at what I'm doing wrong? Camera: Projection = Matrix.CreatePerspectiveFieldOfView( MathHelper.PiOver4, _device.Viewport.AspectRatio, 1.0f, 1000.0f ); Matrix camRotMatrix = Matrix.CreateRotationX( _cameraPitch ) * Matrix.CreateRotationY( _cameraYaw ); Vector3 transCamRef = Vector3.Transform( _cameraForward, camRotMatrix ); _cameraTarget = transCamRef + CameraPosition; Vector3 camRotUpVector = Vector3.Transform( _cameraUpVector, camRotMatrix ); View = Matrix.CreateLookAt( CameraPosition, _cameraTarget, camRotUpVector ); Model: World = Matrix.CreateTranslation( Position );

• How to display recently installed programs and when they were installed?

  - by salvationishere

  I have a Windows XP and I just installed about 12 new programs. Big mistake! Before I installed these programs, my internet connection was running great. But now after installing and restarting my laptop, the internet is crawling. How can I see what was changed? Hint: prior to installing these 12 programs, I installed IE version 8. So probably if I removed that it would fix it, but the problem is I need IE in order for my SQL/C# web application to work properly.

• Connecting/Adding a private network on windows server 2008

  - by WhyMe

  Hey all, I have a dual server configuration on a host provider using VPS. I was told by my Host provider that in order to use free bandwidth between my two servers (they are in the same location) I need to add a alias "subnet" to a specific ip (A private network, VPN). How do I add an aliased ip in widnwos? in Linux the relevant command is supposed to be (By my search in blogs) "ifconfig eth0:1 10.129.175.165 netmask 255.255.255.0" They also said that another way to connect between the servers (should also be faster) is to use "private lan", but as it happens I don't know how to define one :(. Is there a windows equivalent or another way to do this? I have checked my ip config and found no indication of the private lan or the VPN ip.

• Tools to manage large network of heterogeneous web applications?

  - by Andrew

  I recently started a new job where I've been tasked with managing a global network of heterogenous web applications. There's very little documentation. My first order of business is to create an inventory of all of the web applications. Are there any tools out there to manage a large group of web apps? I'd like to collect a large dataset for each website including: logins for web based control panels logins to FTP/ssh accounts Google analytics tracking code for each site 3rd party libraries used SSL certs, issuers, and expiration dates etc I know I could keep the information in Excel or build a custom database, but I'm hoping there's already a tool out there to help me with this.

• Lucene best practice

  - by Dragos

  I am trying to understand how Lucene should be used. From what I have read, creating an IndexReader is costly, so using a Search Manager shoulg be the right choice. However, a SearchManager should be produced by a NRTManager(which, by the way, should replace the IndexWriter for every add or delete operation performed). But in order to have a NRTManager, I should first have an IndexWriter, and here comes my problem. The documentation says: an IndexWriter is thread-safe the constructor of this class takes a Directory object, so it seems creating an instace should be costly(as in the case of an IndexReader) all changes are buffered and flushed periodically(so they seem to encourage using a single instance) but: the changes, although flushed will only be visible after commit or close after finished making updates(add/delete), the instance should be closed I also found this: http://stackoverflow.com/questions/5374419/forgot-to-close-the-lucene-indexwriter-after-adding-documents-to-the-index where it is said that not closing a writer might ruin everything So what am I really supposed to do? Is having a single IndexWriter instance a good idea(make only commit and never close it)? EDIT: What is more, if I use NRTManager, how can I make acommit`? Is it even possible?

• Question regarding Readability vs Processing Time

  - by Jordy

  I am creating a flowchart for a program with multiple sequential steps. Every step should be performed if the previous step is succesful. I use a c-based programming language so the lay-out would be something like this: METHOD 1: if(step_one_succeeded()) { if(step_two_succeeded()) { if(step_three_succeeded()) { //etc. etc. } } } If my program would have 15+ steps, the resulting code would be terribly unfriendly to read. So I changed my design and implemented a global errorcode that I keep passing by reference, make everything more readable. The resulting code would be something like this: METHOD 2: int _no_error = 0; step_one(_no_error); if(_no_error == 0) step_two(_no_error); if(_no_error == 0) step_three(_no_error); if(_no_error == 0) step_two(_no_error); The cyclomatic complexibility stays the same. Now let's say there are N number of steps. And let's assume that checking a condition is 1 clock long and performing a step doesn't take up time. The processing speed of Method1 can be anywhere between 1 and N. The processing speed of Method2 however is always equal to N-1. So Method1 will be faster most of the time. Which brings me to my question, is it bad practice to sacrifice time in order to make the code more readable? And why (not)?

• PASS Summit for SQL Starters

  I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

• Self-Executing Anonymous Function vs Prototype

  - by Robotsushi

  In Javascript there are a few clearly prominent techniques for create and manage classes/namespaces in javascript. I am curious what situations warrant using one technique vs. the other. I want to pick one and stick with it moving forward. I write enterprise code that is maintained and shared across multiple teams, and I want to know what is the best practice when writing maintainable javascript ? I tend to prefer Self-Executing Anonymous Functions however I am curious what the community vote is on these techniques. Prototype : function obj() { } obj.prototype.test = function() { alert('Hello?'); }; var obj2 = new obj(); obj2.test(); Self-Closing Anonymous Function : //Self-Executing Anonymous Function (function( skillet, $, undefined ) { //Private Property var isHot = true; //Public Property skillet.ingredient = "Bacon Strips"; //Public Method skillet.fry = function() { var oliveOil; addItem( "\t\n Butter \n\t" ); addItem( oliveOil ); console.log( "Frying " + skillet.ingredient ); }; //Private Method function addItem( item ) { if ( item !== undefined ) { console.log( "Adding " + $.trim(item) ); } } }( window.skillet = window.skillet || {}, jQuery )); //Public Properties console.log( skillet.ingredient ); //Bacon Strips //Public Methods skillet.fry(); //Adding Butter & Fraying Bacon Strips //Adding a Public Property skillet.quantity = "12"; console.log( skillet.quantity ); //12 //Adding New Functionality to the Skillet (function( skillet, $, undefined ) { //Private Property var amountOfGrease = "1 Cup"; //Public Method skillet.toString = function() { console.log( skillet.quantity + " " + skillet.ingredient + " & " + amountOfGrease + " of Grease" ); console.log( isHot ? "Hot" : "Cold" ); }; }( window.skillet = window.skillet || {}, jQuery )); //end of skillet definition try { //12 Bacon Strips & 1 Cup of Grease skillet.toString(); //Throws Exception } catch( e ) { console.log( e.message ); //isHot is not defined } I feel that I should mention that the Self-Executing Anonymous Function is the pattern used by the jQuery team. Update When I asked this question I didn't truly see the importance of what I was trying to understand. The real issue at hand is whether or not to use new to create instances of your objects or to use patterns which do not require constructors of the use of the new keyword. I added my own answer, because in my opinion we should make use of patterns which don't use the new keyword. For more information please see my answer.

• Is ZeroMQ a good choice to make a Python app and a C# managed assembly work together?

  - by Alex Bausk

  I have a task that involves talking to a .NET-based API (namely AutoCAD) to retrieve data, send commands, and react to events. I want to separate the API operations and the proper program logic (largely already implemented in Python) by using natural tools for both: a C# DLL for the former and a Python app for the latter. To connect these two pieces, I began exchanging JSON in ZeroMQ messages. I'm at early development stages but having recently discovered that ZeroMQ does not guarantee message delivery/order, I have reservations about whether this is a feasible way to go. Right now my app is a very basic REQ/REP pair and I plan to handle reacting to events and executing different commands by adding some sort of 'recipient-function' field to my message format. The reason that I want to use ZMQ is that I might be able to scale the software into a larger, multi-user, distributed solution sometime. I am a lay programmer so I would ask for your advice about this architecture. Should I just go ahead with it and plan to deal with message reliability/ordering when problems appear? Should I consider developing some kind of a REST wrapper around ZMQ?
