• Source File not updating Destination Files in Excel

  - by user127105

  I have one source file that holds all my input costs. I then have 30 to 40 destination files (costing sheets) that use links to data in this source file for their various formulae. I was sure when I started this system that any changes I made to the source file, including the insertion of new rows and columns was updated automatically by the destination files, such that the formula always pulled the correct input costs. Now all of a sudden if my destination files are closed and I change the structure of the source file by adding rows - the destination files go haywire? They pick up changes to their linked cells, but don't pick up changes to the source sheet that have shifted their relative positions in the sheet. Do I really need to open all 40 destination files at the same time I alter the source file structure? Further info: all the destination files are protected, and I am working on DropBox.

• HP Pavilion dv6 overheating, how do I set fan speed to 100% all the time?

  - by henpenben

  So I have a HP Pavilion dv6, and it works fine. But when I play, say, Minecraft, the temperature jumps to around 60c-70c. I wouldn't be bothered by this, but I bought this computer and played Minecraft on my lap. The laptop overheated and the video card melted. (I'm not kidding) So I was wondering how I could set the fan speed on my laptop to 100% all the time so it never overheats. HP has this "HP Coolsense" thing that when I pick up the laptop and wiggle it around a little bit and pretend it's unstable, the fan cranks up to 100%. I want 100% all the time without me having to pick up the laptop every 10 minutes. Thanks, henpenben

• Starting a Java activity in Unity3d Android

  - by Matthew Pavlinsky

  I wrote a small Java activity extension of UnityPlayerActivity similar to what is described in the Unity docs. It has a method for displaying a song picking interface using an ACTION_GET_CONTENT intent. I start this activity using startActivityForResult() and it absolutely kills the performance of my Unity game when it is finished, it drops to about .1 FPS afterwords. I've changed removed the onActivityResult function and even tried starting the activity from inside an onKeyDown event in Java to make sure my method of starting the activity from Unity was not the problem. Heres the code in a basic sense: package com.company.product; import com.unity3d.player.UnityPlayerActivity; import com.unity3d.player.UnityPlayer; import android.os.Bundle; import android.util.Log; import android.content.Intent; public class SongPickerActivity extends UnityPlayerActivity { private Intent myIntent; final static int PICK_SONG = 1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.i("SongPickerActivity", "OnCreate"); myIntent = new Intent(Intent.ACTION_GET_CONTENT); myIntent.setType("audio/*"); } public void Pick() { Log.i("SongPickerActivity", "Pick"); startActivityForResult(myIntent, PICK_SONG); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); } } This is causing me a bit more of a headache than it should and I would be thankful for any sort of advice. Does anyone have any experience with using custom activities in Unity Android or any insight on why this is happening or how to resolve this?

• Electric Dreams: Picking Out a Vintage 1980s Computer [Video]

  - by Jason Fitzpatrick

  What if you had to pick out a 1980s era computer for use in your home today? BBC show Electric Dreams walks us through the history with a “time traveling” family. Electric Dreams is a show based on the novel premise that an average British family is starting, technologically speaking, in the 1970s and progressing over a month to the year 2000–restricted each step of the way to using technology available only in the era they are emulating. In the above video clip they’ve reached 1982 and visit the National Museum of Computing to pick out a vintage computer. It’s interesting to see the kids interact with the computer and experience programming for, presumably, the first time. Have a vintage computer memory (mine is programming on a Timex Sinclair); let’s hear about it in the comments.

• Windows CE: SDK Doesn’t Show up in Visual Studio 2008

  - by Bruce Eitman

  A customer recently contacted me because after installing an SDK it didn’t show up in Visual Studio 2008.  So being a good vendor I installed VS2008 and then installed the SDK – no problem the SDK showed up and I could create projects based on it. I let the customer know that the SDK definitely works with VS2008. The customer got back to me and asked what OS I was using. Hmm, how could that play into this? I told him that I use Windows XP, and it turned out that he is way more modern than I am and is using both Windows Vista and 7. The customer opened a support case with Microsoft. The answer turns out to be that the SDK install requires the user to be logged on as an administrator when installing on Windows Vista and 7 for the SDK to show up in Visual Studio 2008. This problem does not seem to exist for Visual Studio 2005 on those operating systems. The actual instructions from Microsoft Support are: 1)      Make sure Visual Studio 2008 is not running. I also shut down the device emulator manager but you may not be using that. 2)      Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option. 3)      Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file> 4)      When asked if you wish to do a custom or complete install pick custom 5)      Instruct the installer to omit the installation of the documentation. This was something I found about CE 6 SDK installation issue and may have no bearing upon your problem but I did it anyway. 6)      Install   Copyright © 2010 – Bruce Eitman All Rights Reserved

• Advice for a computer science sophomore in college?

  - by RDas

  Hi Everyone! I'm a sophomore in college majoring in Computer Science and Math. I have always loved programming. I started programming in C when I was nine years old and over the years I've picked up Visual Basic, C#, Java, C++, JavaScript, Objective-C, Python, Ruby, elementary Haskell and elementary Erlang, and I learned Perl back in the day which I've mostly forgotten. I have not done much network programming. I have done CGI programming, but that was about six/seven years ago. I've done some socket programming and written (school) programs to do interprocess communication, which I understood and liked. I'm taking a course on client/server programming and another one on network security next semester, which I am really looking forward to. I'm seeking advice on how to proceed with future learning. I've mostly done application (mobile and desktop) development, not much of web development. I'd like to pick up some web development this coming semester. Since I know Ruby and Python, should I start by learning Django and/or Rails? Any other suggestions on starting web development? I have a good understanding of HTML and CSS. Also, I'd also like to know how hard it is to pick up and be good (read: productive) in functional programming languages coming from a purely structured/object oriented background? I've been reading up on Erlang and Haskell, and I'd like to know your opinions on whether it's worth my time trying to learn them. What about Lisp, Scheme and other functional languages? Any help/ideas would be really appreciated.

• Jack of all trades, master of none [closed]

  - by Rope

  I've got a question similar to this one: Is looking for code examples constantly a sign of a bad developer? though not entirely. I got off college 2 years ago and I'm currently struggling with a University study. Most likely I'll have to drop out and start working within the next couple of months. Now here's the pickle. I have no speciality what so ever. When I got out of college I had worked with C, C++ and Java. I had had an internship at NEC-Philips and got familiar with C# (.NET) and I taught myself how it worked. After college I started working with PHP, HTML,SQL, MySQL Javascript and Jquery. I'm currently teaching myself Ruby on Rails and thus Ruby. At my university I also got familiar with MATLAB. As you can see I've got a broad scope of languages and frameworks I'm familiar with, but none I know inside-out. So I guess this kinda applies to me: "Jack of all trades, master of none.". I've been looking for jobs and I've noticed that most of them require some years of experience with a certain language and some specifications that apply to that language. My question is: How do I pick a speciality? And how do I know if I'll actually enjoy it? As I've worked with loads of languages how would I be able to tell this is right for me? I don't like being tied down to a specific role and I quite like being a generalist. But in order to make more money I would need a specialisation. How would I pick something that goes against my nature? Thanks in advance, Rope.

• How to Find Out Which Devices Are Supported By Solaris 11

  - by rickramsey

  Image of monks gathering on the steps of the main hall in the Tashilhunpo Monastery is courtesy of Alison Whitear Travel Photography. In his update of Brian Leonard's original Taking Your First Steps With Oracle Solaris, Glynn Foster walks you through the most basic steps required to get a version of Oracle Solaris 11 operational: Installing Solaris (VirtualBox, bare metal, or multi-boot) Managing users (root role, sudo command) Managing services with SMF (svcs and svcadm) Connecting to the network (with SMF or manually via dladm and ipadm) Figuring out the directory structure Updating software (with the IPS GUI or the pkg command) Managing package repositories Creating and managing additional boot environments One of the things you'll have to consider as you install Solaris 11 on an x86 system is whether Solaris has the proper drivers for the devices on your system. In the section titled "Installing On Bare Metal as a Standalone System," Glynn shows you how to use the Device Driver utility that's included with the Graphical Installer. However, if you want to get that information before you start installing Solaris 11 on your x86 system, you can consult the x86 Device List that's part of the Oracle Solaris Hardware Compatibility List (HCL). Here's how: Open the Device List. Scroll down to the table. Open the "Select Release" pull-down menu and pick "Solaris 11 11/11." Move over to the "Select Device Type" pull-down menu, and pick the device type. Or "All." The table will list all the devices of that type that are supported by Solaris 11, including PCI ID and vendor. In the coming days the Solaris Hardware Compatibility List will be updated with more Solaris 11 content. Stay tuned. - Rick Ramsey Website Newsletter Facebook Twitter

• Do I need path finding to make AI avoid obstacles?

  - by yannicuLar

  How do you know when a path-finding algorithm is really needed? There are contexts, where you just want to improve AI navigation to avoid an object, like a space -ship that won't crash on a planet or a car that already knows where to steer, but needs small corrections to avoid a road bump. As I've seen on similar posts, the obvious solution is to implement some path-finding algorithm, most likely like A*, and let your AI-controlled object to navigate through the path. Now, I have the necessary skills to implement a path-finding algorithm, and I'm not being lazy here, but I'm still a bit skeptical on if this is really needed. I have the impression that path-finding is appropriate to navigate through a maze, or picking a path when there are many alternatives. But in obstacle avoidance, when you do know the path, but need to make slight corrections, is path finding really necessary? Even when the obstacles are too sparse or small ? I mean, in real life, when you're driving and notice a bump on the road, you will just have to pick between steering a bit on the left (and have the bump on your right side) or the other way around. You will not consider stopping, or going backwards. A path finding would be appropriate when you need to pick a route through the city, right ? So, are there any other methods to help AI navigation, except path-finding? And if there are, how do you know when path-fining is the appropriate algorithm ? Thanks for any thoughts

• Naming conventions: camelCase versus underscore_case ? what are your thoughts about it? [closed]

  - by poelinca

  I've been using underscore_case for about 2 years and I recently switched to camelCase because of the new job (been using the later one for about 2 months and I still think underscore_case is better suited for large projects where there are alot of programmers involved, mainly because the code is easier to read). Now everybody at work uses camelCase because (so they say) the code looks more elegant . What are you're thoughts about camelCase or underscore_case p.s. please excuse my bad english Edit Some update first: platform used is PHP (but I'm not expecting strict PHP platform related answers , anybody can share their thoughts on which would be the best to use , that's why I came here in the first place) I use camelCase just as everibody else in the team (just as most of you recomend) we use Zend Framework which also recommends camelCase Some examples (related to PHP) : Codeigniter framework recommends underscore_case , and honestly the code is easier to read . ZF recomends camelCase and I'm not the only one who thinks ZF code is a tad harder to follow through. So my question would be rephrased: Let's take a case where you have the platform Foo which doesn't recommend any naming conventions and it's the team leader's choice to pick one. You are that team leader, why would you pick camelCase or why underscore_case? p.s. thanks everybody for the prompt answers so far

• How do I choose a package format for Linux software distribution?

  - by Ian C.

  We have a Java-based application that, to date, we've been distributing as a tarball with instructions for deploying. It's mostly self-contained so deployment is fairly straight-forward: Untar on the disk you'd like it to live on; Make sure Java is in your path and a suitable distro and version; Verify ownership and group on all the files Start up the server processes with our start script If the user wants to get in to start-on-boot stuff with SysV we have some written instructions and a template init file for it in our tarball. We'd like to make this installation process a little more seamless; take care of the permissions and the init script deployment. We're also going to start bundling our own JRE with the application so that we're mostly free of external dependencies. The question we're faced with now is: how do we pick a package format for distribution? Is RPM the standard? Can all package management tools deal with it now? Our clients primarily run RHEL and CentOS, but we do have some using SuSE and even Debian. If we can pick a distro-agnostic format we'd prefer that. What about a self-extracting shell script? Something akin to how Java is distributed. If we're dependency-free would the self-extracting script be sufficient? What features or conveniences would we lose out on going with the script versus a proper package format meant for use by a package manager?

• How do I get google to see keywords on a one page web application site?

  - by David

  I'm going to have to link to the web site to explain this, http://www.diagram.ly, it's a free service, so I hope this doesn't break advertising rules. Basically, it's a one page web application, I don't want to create a web site for it. Some background text loads and if JavaScript is enabled, the web application itself then loads. The problem is that Google only seems to be picking up the title of the page and the text on the footer, so the site only appear on Google search for very limited text (based on the title and meta description mostly). I was hoping that search engines would pick up on the background text and index that. The text is factual, not keyword stuffed. Yahoo seems to pick up the text, just not Google. Does anyone have any experience of how Google would view such a site and where I could put the text for a better result? Edit I should mention that Google Webmaster Tools lists the site keywords as "Component, diagramly, feed, mxgraph, share and twitter". Basically the footer and little else.

• SSW Scrum Rule: Do you know to use clear task descriptions?

  - by Martin Hinshelwood

  When you create tasks in Scrum you are doing this within a time box and you tend to add only the information you need to remember what the task is. And the entire Team was at the meeting and were involved in the discussions around the task, so why do you need more? Once you have accepted a task you should then add as much information as possible so that anyone can pick up that task; what if your numbers come up? Will you be into work the next day? Figure: What if your numbers come up in the lottery? What if the Team runs a syndicate and all your numbers come up? The point is that anything can happen and you need to protect the integrity of the project, the company and the Customer. Add as much information to the task as you think is necessary for anyone to work on the task. If you need to add rich text and images you can do this by attaching an email to the task.   Figure: Bad example, there is not enough information for a non team member to complete this task Figure: Julie provided a lot more information and another team should be able to pick this up. This has been published as Do you know to ensure that relevant emails are attached to tasks in our Rules to Better Scrum using TFS.   Technorati Tags: Scrum,SSW Rules,TFS 2010

• Implementing the transport layer for a SIP UAC

  - by Jonathan Henson

  I have a somewhat simple, but specific, question about implementing the transport layer for a SIP UAC. Do I expect the response to a request on the same socket that I sent the request on, or do I let the UDP or TCP listener pick up the response and then route it to the correct transaction from there? The RFC does not seem to say anything on the matter. It seems that especially using UDP, which is connection-less, that I should just let the listeners pick up the response, but that seems sort of counter intuitive. Particularly, I have seen plenty of UAC implementations which do not depend on having a Listener in the transport layer. Also, most implementations I have looked at do not have the UAS receiving loop responding on the socket at all. This would tend to indicate that the client should not be expecting a reply on the socket that it sent the request on. For clarification: Suppose my transport layer consists of the following elements: TCPClient (Sends Requests for a UAC via TCP) UDPClient (Sends Requests for a UAC vid UDP) TCPSever (Loop receiving Requests and dispatching to transaction layer via TCP) UDPServer (Loop receiving Requests and dispatching to transaction layer via UDP) Obviously, the *Client sends my Requests. The question is, what receives the Response? The *Client waiting on a recv or recvfrom call on the socket it used to send the request, or the *Server? Conversely, the *Server receives my requests, What sends the Response? The *Client? doesn't this break the roles of each member a bit?

• Frustrated with MythTV 0.26

  - by Mike

  I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

• Defining formula through user interface in user form

  - by BriskLabs Pakistan

  I am a student and developing a simple assignment - windows form application in visual studio 2010. The application is suppose to construct formulas as per user requirement. The process: It has to pick data from columns of Microsoft Access database and the user should be able to pick the data by column name like we do in a drop down menu. and create reusable formulas in it ( configure it once and can change it again). followings are column titles from database that can be picked for example. e.g Col -1 : Marks in Maths Col -2 : Total Marks in Maths Col -3 : Marks in science Col -4 : Total marks in science Finally we should be able to construct any formula in the UI like (Col 1 + Col 3 ) / ( col 2 + col 4) = Formula 1 once this is formula is set saved and a name is assigned to it by user. he/she can use the formula and results shall appear in a window below. i.e He would be able to calculate his desired figures (formula) by only manipulating underlying data on the UI layer....choose the data for a period and apply the formula and get the answer Problem: It looks like I have to create an app where rules are set through UI....... this means no stored procedures are required in SQL.... please suggest the right approach.

• Is it a must to focus on one specific IT subject to be succesful?

  - by Ahmet Yildirim

  Lately I'm deeply disturbed by the thought that I'm still not devoted to one specific IT subject after so many years of doing it as a hobby. I've been in so many different IT related hobbies since I was 12. I have spent 8 years and now I'm 20 and just finished freshman year at Computer Eng. Just to summarize the variety: 3D Game Dev. and Modelling (Acknex, Irrlicht , OpenGL, GLES, 3DSMAX) Mobile App.Dev (Symbian, Maemo, Android) Electronis (Arduino) Web.Dev. (PHP, MYSQL, Javascript, Jquery, RaphaelJS, Canvas, Flash etc.) Computer Vision (OpenCV) I need to start making money. But I'm having problem to pick the correct IT business to do so. Is it a problem to have interest in so many different IT subjects?(in business world) I'm having a lot of fun by doing all those stuff from time to time. Other than making money I also noticed that having so many different interests is lowering my productivity. But I'm still having difficulty to pick one. I'm feeling close to all those subjects (time to time).

• SharePoint Saturday Huntsville Wrap Up

  - by Mark Rackley

  So, Cathy Dew (@catpaint1) and company put on a great SharePoint Saturday event this past weekend. I got to hang out with some old friends and meet some new ones. I’d list you all, but I’d undoubtedly miss someone and don’t want to offend anyone.  Although I find it odd that I see @MossLover now more since she moved to New Jersey than when she lived next door in Kansas City… what’s up with that? Anyway, Cathy did a tremendous job organizing the event.  Everything went smoothly and everyone had a great time. Maybe I can talk her into organizing the rest of SharePoint Saturday Ozarks on June 12th… you know that’s coming up? right? While you’re here why not go ahead and register right now at: http://spsozarks.eventbrite.com/  Yes.. that was a shameless plug… I did my default presentation on “Wrapping Your Head Around the SharePoint Beast”. This continues to be my most popular presentation. I try to tweak it every time and I always have fun doing it. I get to pick on people and they pick on me back, but I always manage to learn something new when I present it. I had a great interactive crowd and they didn’t throw anything at me.  All in all I consider it a success.  Thanks for coming if you attended!  You can get the slides here:  SharePoint Saturday Huntsville - Wrapping Your Head Around the SharePoint Beast Next up for me is SharePoint Saturday DC on May 15th.  Wow this is going to be a huge event with space for 1500 attendees.. no, that is not a typo!  Stop me and say hi if you are able to make it!!

• Ubunto 12.10 Boots to purple screen

  - by Ric

  I know this question has been tackled in a couple different threads but I've tried what I could from those and have not resolved the issue. I have just a basic understanding of this system so feel free to talk down to me or explain this like you would to a 5 year old. Let's start from the beginning. My son has a computer built by an IT friend of mine (we moved so he can't help any more). It had Windows XP running on it and it just stopped working correctly. This same friend had built a laptop for me with Ubuntu which I liked so I thought I'd put a new OS on my sons computer and it may work better. I downloaded Ubuntu 12.10 onto a USB drive and loaded it onto his computer. I followed all the prompts, it installed, I restarted the computer, it gives me the option of which OS to pick. I pick Ubuntu and it seemingly loads. The desktop comes up with just the basic pinkish Ubuntu background but that is it. There are no icons. I can't right click anywhere to create a file. Left clicking the mouse does not create a square when moved. Alt + F2 doesn't do anything. I can open a terminal but any of the commands I have seen in previous threads do not correct any issues. What else can I do, or what resources are available to fix this problem? I don't know if there are additional files on the USB drive that I need to access or what. Also, one of the problems we were having with my sons computer is that windows would only load to a blank screen. It runs accordingly in safemode and my install of Ubuntu was through safemode of Windows XP.

• What's so great about Clojure?

  - by marco-fiset

  I've been taking a look at Clojure lately and I stumbled upon this post on Stackoverflow that indicates some projects following best practices, and overall good Clojure code. I wanted to get my head around the language after reading some basic tutorials so I took a look at some "real-world" projects. After looking at ClojureScript and Compojure (two the the aforementioned "good" projects), I just feel like Clojure is a joke. I don't understand why someone would pick Clojure over say, Ruby or Python, two languages that I love and have such a clean syntax and are very easy to pick up whereas Clojure uses so much parenthesis and symbols everywhere that it ruins the readability for me. I think that Ruby and Python are beautiful, readable and elegant. They are easy to read even for someone who does not know the language inside out. However, Clojure is opaque to me and I feel like I must know every tiny detail about the language implementation in order to be able to understand any code. So please, enlighten me! What is so good about Clojure? What is the absolute minimum that I should know about the language in order to appreciate it?

• Should one use a separate database for application data and user data?

  - by trycatch

  I’ve been working on a project for a little while and I’m unsure which is the better architecture. I’m interested in the consensus. The answer to me seems fairly obvious but something about it is digging at me and I can't pick out what. The TL;DR is: how do you handle a program with application data and user data in the same DB which needs to be able to receive updates to the application data periodically? One database for user data and one for application, or both in one? The detailed version is.. if an application has a database which needs to maintain application data AND user data, and the user data all references application data, it feels more natural to me to store them in the same database. But if there exists a need to be able to update the application data within this database periodically, should this be stripped into two databases so that one can simply download the updated application data database file as an update and replace the old one? Or should they remain as one database, and the application data be updated via a script which inserts the new data into the existing database? The second sounds clearly preferable to me... but for some reason just doesn’t feel right, and I can't pick out quite why.

  Problem I have X, a positive integer, of some resource, R. There are N potential targets. I want to distribute all of R to the N targets in some "interesting" way. "Interesting" means: Some targets may not get any R. It should rarely be near even (with a majority of target getting near X/N of the resource). There should be at least a small chance of one target getting all of R. Bad solutions The naive approach would be to pick a random target and give one R to it and repeat X times. This would result in too even of an approach. The next idea is to pick a random number between 1 and X and give it to a random target. This results in too large of a number (at least X/2 on average) being given to one target. Question This algorithm will be used frequently and I want the distribution to be interesting and uneven so that the surprise doesn't wear off for users. Is there a good algorithm for something in between these two approaches, that fits the definition of interesting above?
