• How to change color of a cell in one sheet if its value increases or decreases from another cell value in a different sheet

  - by Sean Coffey

  I am putting together a workbook with 52 sheets for the weeks in the year. In this workbook there are multiple columns for percentages on each sheet. I want to be able to change the color of each cell based on whethernit increases (green) or decreases (red) from the same cell in the previous sheet. I have the formula i.e. =IF(ISERROR(B4/D4),"0", B4/D4) to calculate my percentages but I don't know how to put the reference in for this change. Any help?

• Two keyboards - one qwerty one dvorak. Can windows use both simultaneously?

  - by Alain

  Similar to this question: Is it possible to use multi keyboards with multi keyboard layouts simultaneously? - I have two keyboards plugged in simultaneously. Both are querty keyboards, but I've rearranged the keys on one to be a dvorak layout. I'd like to find some way to configure windows (XP) such that while both keyboards are plugged in, typing on each results in it's respective layout. I'd prefer if there was someway to have the system automatically use the desired layout based on which USB keyboard it is receiving input from. If no such solution is possible, I would settle for a fast way of switching between US English and US English Dvorak languages so that in a pinch I can easily go from one to the other. Thanks.

• Grouping extensions in Asterisk

  - by Matt

  We have an asterisk based phone system with multiple clients connected to it. At the moment, all the extension numbers fall in the range 100 - 9999. But, now we have an issue where a particular customer wants to come onto our service and insists on keeping their existing extension list. Is there a way of having extensions 700 for one customer, and also the same number range to another customer. But yet having them belong to a different group? I see there is a concept of groups in asterisk but none of them seem to provide a solution to this.

• Backing up data (including mysqldumps) to S3

  - by seengee

  We have a web app on a number of servers and we want to add an additional layer of redundancy by backing up the key data to S3. The key data is the MySQL database and a folder containing dynamically created site assets - predominantly images. Some kind of rsync based solution would initially seem the best plan. A couple of years ago we played with S3cmd (in particular s3cmd sync) with some success but we didn't find it particularly reliable although this may have changed since. Its occurred to me though that a rsync solution might not work particularly well with a single db.sql file created with mysqldump and I assume this means the whole database getting transferred each time, with multiple databases of over 1GB this is going to add up to a lot of traffic (and $s) very quickly. With the image files I could simply just transfer files modified within the last day which would be far more simple. What approach should I look at?

• How can I automate my Linux computer to power off (and on preferably) under certain circumstances?

  - by Ashimema

  OK, So a little background; I've been using Windows Home Server as a Backup Appliance, Media Server and Share Server at home for some time. I decided it was costing me allot of juice so very early on added the "Lights Out" add-on to ensure it was only running as and when needed. I'm now looking to switch to a Linux based server and I'm looking for a similar tool/set of tools for advanced power management. Now the question; Anyone got any all-in-one suggestions (i.e with client parts for both Windows and Linux and a server part for the Linux server), or can anyone simply verify that I'll need to set-up all the individual bits for this myself separately? (A tool similar to "[SmartPower][2]" but for linux would be a great start)

• Application to handle form approval

  - by ChrisMuench

  Hello, Hopefully this is the right place for this question. I have done a fair amount of research and yet to find anything that matches what I want. What I'm envisioning is the following. Let me know if any of you know of a program that will do what I want. Also it must be web-based anom user - fills out form - email gets sent to admin saying xyz has filled out form abc with links to approve/disapprove request. admin can also login and edit form and resent results to original submitter. Also once the admin approves/disapproves request the original submitter gets an approve/disapprove email. and you can search by date submitted, specific project/form, status of request(submitted, approved, disapproved). any ideas all on where I could find this? I started to look into drupal with workflows and actions but it just doesn't flow right for this

• SOA: Simplifying Cloud, Mobile, and On-premise Integration–Webcast October 24th 2013

  - by JuergenKress

  Proliferation of mobile devices, data explosion, and cloud enablement has caused a dramatic shift in IT. Organizations need to rethink their application infrastructures to accommodate increased processing speeds, heightened security and availability concerns for their applications, all while meeting lowered total cost of ownership. Traditional infrastructures may not be sufficient to accommodate the diversity and complexity of integrations in this new era. Many of today’s IT organizations rely on a Service Oriented Architecture (SOA) backbone to keep their businesses running. SOA adoption and acceptance across industries have led to platform maturity at the application layer level. However, we are at the start of an era where there is a new modus operandi for organizations to thrive and deliver continuously on competitive differentiation. This change is a result of market globalization, explosion in the number of mobile devices, unparalleled growth in voluminous data and innovation that crosses organizational boundaries. Social, mobile, cloud are terms that are revolutionizing the way organizations operate. Oracle SOA Suite is a hot-pluggable software suite to build, deploy and manage Service-Oriented Architectures (SOA).Oracle SOA transforms complex application integration into agile and reusable service-based connectivity by mediating, routing, and managing interactions between services and applications in the enterprise and in the cloud. Oracle SOA Suite's hot-pluggable architecture helps businesses lower upfront costs by allowing maximum re-use of existing IT investments and assets. Join us on this webcast to find out how you can optimize the use of Oracle SOA Suite, simplifying integration, and what does the next generation of SOA has to offer to you. Agenda: What's new in Oracle SOA Simplifying integration Application Integration and SOA Cloud integration with SOA Mobile Integration leveraging Oracle SOA Suite Oracle Delivers on Next Generation SOA Customer Examples Summary and Q&A Webcast Thursday October 24th, 2013 10am CET (8am UTC / 11am EEST)Details at the Registration Page SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• Find keyword values from PDF [closed]

  - by JukkaA

  I have a lot of PDF reports I'd need to index. They're mostly "text-based PDFs", not images. I know they all have account number in certain format, 123456AAAAA and some other keyword info like addresses, customer names etc. needed in indexing these files. Basically if the file is ab.pdf, I need to create ab.txt that contains: ACC=123456AAAA Customer=John Doe Date=20120808 What would be the best software/solution to generate indexing information for these? I know there's pdftotext, but piping it to different grep/awk commands is a hack... It would be nice to specify an area in PDF to search for the account number, and specify the format it is in.

• Transformation?

  - by Joe G

  I started working at Oracle in 1997.  Since then, we (and most everyone) have been talking about transforming finance operations....but what does that mean exactly?  From my perspective, I thought it meant eliminate waste and menial tasks and giving your finance team more time to work on more strategic things.  That seems logical and simplistic, but how much progress have finance teams (and their IT departments) really made over the past fifteen years? I have yet to talk to a customer that doesn't have one amusing task that makes me chuckle.  Sometimes they still print hard copies of transactions to "file," or sometimes they print 700 pages of data to "analyze," or sometimes they cut and paste from one or more reports into a spreadsheet.  Upon hearing these things, my first question is always, "Why do you do that?" to which their response is rarely the same.    Sometimes it's related to trust (both the employee and the system).  Sometimes, it's habit-based.  And sometimes it is just impossible to accomplish the end result without some manual effort. I will say that I used to print nearly everything that I needed to review.  Partly, because I liked having the ability to scribble notes on the paper, and partly, because it was uncomfortable to read online.  However, I have changed. Rarely do I print anything anymore.  It's easier for me to read and notate online, and well, I guess I've just changed my habits. So where do you think our resistance to change comes from?  Is it truly deficits in our systems, or is it our own personal resistance to change?  What's your most annoying & untransformed task?

• How to store a list of Objects that might change in future?

  - by Amogh Talpallikar

  I have set of Objects of the same class which have different values of their attributes. and I need to find the best match from a function under given scenarios out of these objects. In future these objects might increase as well. Quite similar to the way we have Color class in awt. we have some static color objects in the class with diff rgb values. But in my case say, I need to chose the suitable color out of these static ones based on certain criteria. So should I keep them in an arrayList or enum or keep them as static vars as in case of Colors. because I will need to parse through all of them and decide upon the best match. so I need them in some sort of collection. But in future if I need to add another type I will have to modify the class and add another list.add(object) call for this one and then it will violate the open-close principle. How should I go about it ?

• touch detection of non-rectangular sprites (cocos2d)

  - by hogni89

  What is the correct way to implement a non-rectangular sprite in Cocos2d? I am working on a jigsaw puzzle. And therefor do our sprites have some strange forms (Jigsaw puzzle bricks). As of now, we have implemented the "detect" this way: - (void)selectSpriteForTouch:(CGPoint)touchLocation { CCSprite * newSprite = nil; // Loop array of sprites for (CCSprite *sprite in movableSprites) { // Check if sprite is hit. // TODO: Swap if with something better. if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) { newSprite = sprite; break; } } if (newSprite != selSprite) { // Move along, nothing to see here // Not the problem } } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; [self selectSpriteForTouch:touchLocation]; return TRUE; } I know that the problem is in the keyword "sprite.boundingBox". Is there a better way of implementing this, OR is it a limit when using sprites based on .png's? If so, how should I proceed? I'm new to iPhone and game development :D

• Jumbo Frames on DIR-655

  - by Spookyone

  I am trying to set up jumbo frames on my gigabit home LAN but no luck so far. My setup is: D-Link DIR-655 router, HW Revision A3, Firmware 1.21 EU Synology DS107+, Firmware 3.0-1337 Laptop w/ Win7 x64, external PCIx NIC managed by "Generic Marvel Yukon 88E8053 based Ethernet Controller" The router is supposed to support jumbo frames but doesn't feature any relevant setting. I set the Jumbo Packet value to 9000 on both the NIC and the Synobox but it doesn't work, ping -f -l 8972 says "Packet needs to be fragmented but DF set". Is there any other setting I overlooked, the DIR-655 doesn't actually support jumbo frames, or what else could be the problem?

• Process video (canon) mov files

  - by user613326

  Well i would like to program something to process HDR made by magic lantern a canon add on. That doesnt change the format its just some kind of add on, that can produce HDR video. Its a bit complex to make such videos so i would like to use some math and make it myself and makee the software freeware (as a thanks to the creators of magic lantern). The problem with that HDR that normal converts have a lot of artifacts, and i would like to make something (for free) using some new algorithms. I have made, this works fine on individual images, my ideas work. I would want to do this on that canon 60d video format. Canons mov format, and am so far out of luck to read that out. It must be possible dough as i know in some projects they do it too. I would not like to export a movie first to jpg and then back to video as that requires a lot of disk space, i would like to retrieve individual frames, do my math based multiple frames, and then build a new movie on it. The output video can be of any type, avi or mov again. Does anyone know of a library who can do that ? (read and save), So i could use it in a C# project (i prefer C# above c++, but c++ is an option to program in to for me).

• How to choose between Tell don't Ask and Command Query Separation?

  - by Dakotah North

  The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then changing the state of the object. The logic you are implementing is probably the called object’s responsibility, not yours. For you to make decisions outside the object violates its encapsulation. A simple example of "Tell, don't Ask" is Widget w = ...; if (w.getParent() != null) { Panel parent = w.getParent(); parent.remove(w); } and the tell version is ... Widget w = ...; w.removeFromParent(); But what if I need to know the result from the removeFromParent method? My first reaction was just to change the removeFromParent to return a boolean denoting if the parent was removed or not. But then I came across Command Query Separation Pattern which says NOT to do this. It states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects. Are these two really at odds with each other and how do I choose between the two? Do I go with the Pragmatic Programmer or Bertrand Meyer on this?

• Any website/software where i can add some text rows on daily basis

  - by Moorage

  I have few notes or text like few remembering lines on daily or weekly basis. I want to write it. but i should be able to see at any backdate /monthly or yearly. The date-time should also be stored when i enter text. is it possible EDIT: I will explain clearly what i exactly want. Suppose while working on internet 1)i find "ABC is good for BCD". now i want to add that text to some online site where i can see later 2)Now i can add those type of things any time and on internet i can see that in tabular form like click to see montly list , yearly or weekly 3)Other thing is i should be able to add text as easy as possible like in firefox if i can press some shotcut and enter something and it gets added there rather than opening the site and then write The to do list do that sort of thing but they dont have creation date , rather they filter based on due date.

• Automatic driver search & update on Windows?

  - by Ben

  I have a Dell laptop issued by my employer, and I always find it a real pain to search for, download and maintain their drivers. It baffles me that there does not seem to be a nice way (product, website, ...) to just download the stuff you need, without hassle. The same goes for the other Windows based laptops in my direct environment. Are there any (preferably free) automated solutions available? Or do you have a nice workflow - other than searching the manufacturers website - to help smoothing this process?

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• What to do if you were scammed by a web hosting company? [on hold]

  - by Cain Nuke

  I was recently scammed by a web hosting company. Is there anything i can do about it? I would like to sue them but that doesn't sound realistic to me since they are not based on the same country as me. I would like to at least be able to have them blacklisted or something so other people don't get scammed too. I would appreciate if you can tell me how to proceed in these cases. They promise 24/7 support which is not true because its only one guy managing the whole thing and your server can go down for days and he doesn't do anything, he wont even reply your tickets. My server is been offline for over a week now and he only ignores me. I paid for this month and shortly after that my server went offline. I used Paypal to pay. He is in Bulgaria (that's what he says) i'm in Japan. I paid $55 USD.

• What are people using as Login scripts in large enterprises

  - by beakersoft

  Hi, We have recently been tasked with looking after the user login side of things in our enterprise (windows clients in active directory). We have a system at the moment that uses a vbscript login/loggof script to call a couple of DLL written in vb 6. The DLL's actions are controled by some config files based on users/groups witch is administrated from a central app. This is quite a good system, but kind of want to come away from vb6 for the dll's (maybe port them to c++ but them you have to make them com+ to call them from vbscripts etc) and possibly away from vbscript for the actual login scripts themselves. Just wondered what other people are using, what people can suggest etc Thanks Luke

• Access Control Service: Programmatically Accessing Identity Provider Information and Redirect URLs

  - by Your DisplayName here!

  In my last post I showed you that different redirect URLs trigger different response behaviors in ACS. Where did I actually get these URLs from? The answer is simple – I asked ACS ;) ACS publishes a JSON encoded feed that contains information about all registered identity providers, their display names, logos and URLs. With that information you can easily write a discovery client which, at the very heart, does this: public void GetAsync(string protocol) {     var url = string.Format( "https://{0}.{1}/v2/metadata/IdentityProviders.js?protocol={2}&realm={3}&version=1.0",         AcsNamespace,         "accesscontrol.windows.net",         protocol,         Realm);     _client.DownloadStringAsync(new Uri(url)); } The protocol can be one of these two values: wsfederation or javascriptnotify. Based on that value, the returned JSON will contain the URLs for either the redirect or notify method. Now with the help of some JSON serializer you can turn that information into CLR objects and display them in some sort of selection dialog. The next post will have a demo and source code.

• Can we use Google Earth images by applying our Unity3D mesh ?

  - by Jake M

  We are developing a commercial app for iOS and Android. The app will display development plans(architectural drawings) in a real world 3D environment. The app will work by creating a Unity3D mesh, applies a google earth image as the texture then draws out 3d lines(architectural drawings) over the Unity Mesh. Question: We are unsure if this is allowed under Google's terms and agreements? See quoted text below. In the bold text below its a little vague whether what we are doing(explained above) is violating their terms and agreements. What do you think? Does anyone know how we contact google to ask them? You may not mass download or use bulk feeds of any Content, including but not limited to extracting numerical latitude or longitude coordinates, geocoding, text-based directions, imagery, visible map data, or Places data (including business listings) for use in other applications. You also may not trace Google Maps or Earth as the basis for tracing your own maps or geographic materials. For full details, please read section 10.3.1 of the Maps/Earth API Terms of Service. Does anyone have any advice/experience dealing with this stuff?

• What Computing/Programming Qualifications should I aspire for

  - by indevel

  I am a computing science post graduate in my first job from after my degree. During my 12 month review my boss posed the question "What can we do for you in terms of progressing your career?". This got me thinking, after university I hadn't really thought about what other qualifications were available. So this is my question, what courses/qualifications should I be looking to do. Which are highly regarded and which would be really useful to complete. I've searched Google it but all I see is a jumble of courses with no idea of the credibility of each. Any help is much appreciated. I'm traditionally a systems architect, but with this job I've turned to more embedded work so Id like to edge towards electronics, embedded programming, real time OS to help with my work also it would be more likely to be accepted if it was related to my job. Finally UK based courses/ qualifications are a must as travel is probably out of the question. Help me grow as a programmer.

• How to Architect a system on AWS for scaling (with a MySQL back-end)

  - by Edan Maor

  I'm trying to understand how to architect an Amazon Web Services application. As I understand it, the whole point of using something like AWS is to make the eventual scaling easier, so I'm trying to understand how to do that. I have an instance, running off of EBS (EBS-based instance, not a regular instance). My application (a Django app) uses MySQL as a back-end. So the question is, where am I supposed to install the MySQL? Do I install it on the same instance? In which case, as far as I can tell, I can't simply create more server instances from that image. Or am I supposed to simply spin up another server as a DB server, and run off of that? Thanks for any help!

• Backup XAMPP (Htdocs & MySQL)

  - by Max

  I have a development server, but would like to backup everything at least daily to a remote location. I would like to backup the htdocs folder and the MySQL servers. But if possible also the settings of the server and anything else relevant. At the moment I am using DropBox for the htdocs, but this is not ideal. I have looked into Git, DropBox simple copy paste on a daily basis. I was wondering what any advice would be. For example how hard would it be to set it up as a cloud based system? Any and all advice is greatly appreciated.
