  • Learn to Take a Punch, Learn to Counter, Keep Moving Forward

    - by D'Arcy Lussier
    Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/10/28/154483.aspxDuring a boxing workout a few months ago our trainer had us do something called “breadbaskets”. That’s where you hold your arms up and a partner punches you in your midsection – your breadbasket. I put my arms up, and braced for impact. The trainer came over, saw I was a bit nervous, and coached me through. I can see the fear in your eyes. Don’t be afraid to take the punch. Tighten your core, breathe through the hit. Don’t panic. Over the summer we’d do counter drills as well. This is where a partner throws a punch, you defend but also throw one back – a counter punch. You never just sit back and take a beating, you deflect the blow and come back with one more powerful. These lessons on fighting can apply to all aspects of our lives and any attempts at success that we have. I saw this image recently and agree with it 100%: Success is never a straight forward line. It’s messy, its wrought with failures, its learning over time and applying those life lessons. It’s learning how to take punches and lose your fear, its seeing a punch coming and countering it, but most of all its not giving up and continually moving forward. We do stairs at boxing, which is running up and down three flights of stairs. I’m not anywhere near incredible shape and after doing multiple stairs in a single workout you can feel gassed, tired, even discouraged after hitting the second floor and seeing everyone else running by you. I read a quote from Martin Luther King Jr. that I cling to throughout my day: You want to be successful? Take the punches, but learn how to take them. Counter them. and no matter what, always move forward.

  • Identify which CCSprite is touched in Cocos2d

    - by PeterK
    I am trying to learn Cocos2d and is experimenting with Ray Wenderlich tutorial whack-a-mole: www.raywenderlich.com/2560/how-to-create-a-mole-whacking-game-with-cocos2d-part-1 In this tutorial three CCSprite's are popping up and you should click on them... However, i am trying to identify which mole, rat in my case, is popping up and place a CCSprite above that. Initially this looked like an easy task but i am failing. I am trying to NSLog LEFT HIT. i would guess the problem is in the If-statement and the last "227" height parameter. The left rat boundingBox = {{99.5, 146.5}, {165, 227}} (from NSLog). The key code is in the ccTouchBegan function: -(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; for (CCSprite *rat in rats) { if (rat.userData == FALSE) continue; if (CGRectContainsPoint(rat.boundingBox, touchLocation)) { //left: rat boundingBox = {{99.5, 146.5}, {165, 227}} //mid: rat boundingBox = {{349.5, 146.5}, {165, 227}} //right: rat boundingBox = {{599.5, 146.5}, {165, 227}} //>>>>Here is where i try to get a hit<<<< if (CGRectContainsPoint(CGRectMake(99.5, 146.55, 165, 227), touchLocation)) { NSLog(@">>>>HIT LEFT<<<<<"); } I would really appreciate a few ideas how to get this to work.

  • How old is "too old"?

    - by Dori
    I've been told that to be taken seriously as a job applicant, I should drop years of relevant experience off my résumé, remove the year I got my degree, or both. Or not even bother applying, because no one wants to hire programmers older than them.1 Or that I should found a company, not because I want to, or because I have a product I care about, but because that way I can get a job if/when my company is acquired. Or that I should focus more on management jobs (which I've successfully done in the past) because… well, they couldn't really explain this one, except the implication was that over a certain age you're a loser if you're still writing code. But I like writing code. Have you seen this? Is this only a local (Northern California) issue? If you've ever hired programmers:2 Of the résumés you've received, how old was the eldest applicant? What was the age of the oldest person you've interviewed? How old (when hired) was the oldest person you hired? How old is "too old" to employed as a programmer? 1 I'm assuming all applicants have equivalent applicable experience. This isn't about someone with three decades of COBOL applying for a Java guru job. 2 Yes, I know that (at least in the US) you aren't supposed to ask how old an applicant is. In my experience, though, you can get a general idea from a résumé.

  • Wammu - USB Device Name?

    - by Paul
    I'm trying to get to my phone's filesystem through USB in Wammu, but I'm stuck in the configuration wizard when it asks for a USB device name. After about an hour of Internet searching, here are the failed solutions I've already tried, starting with the relevant information returned by lsusb in terminal. lsusb Bus 001 Device 003: ID 12d1:101e Huawei Technologies Co., Ltd. So I tried opening Wammu through sudo wammu in terminal and inputting "/dev/bus/usb/001/003" as the device name, which returns: Error opening device Device /dev/bus/usb/001/003 does not exist! and then "/dev/bus/usb/001/", which returns: Failed to connect to phone Description: Error opening device. Unknown, busy, or no permissions.<br> Function: Init<br> Error code: 2 Another proposed solution was to try "tail -f /var/log/messages" in terminal. But that only returned a "No such file or directory" message. Seemingly relevant dmesg info: [ 4739.716214] usb 1-1: new high-speed USB device number 8 using ehci_hcd [ 4739.854137] scsi9 : usb-storage 1-1:1.0 [ 4740.854416] scsi 9:0:0:0: CD-ROM HUAWEI T Mass Storage 2.31 PQ: 0 ANSI: 2 [ 4740.867051] sr0: scsi-1 drive [ 4740.867806] sr 9:0:0:0: Attached scsi CD-ROM sr0 [ 4740.870464] sr 9:0:0:0: Attached scsi generic sg1 type 5 I don't know why it is coming up as CD-ROM. But there it is. If you haven't noticed already, I'm an absolute beginner when it comes to Linux and terminal. So speaking to me like I'm a three year old is welcome if you can propose a solution. I'm running Ubuntu 12.04 LTS, and the phone is a Huawei U1250. My computer is an Acer Aspire One D250/KAV60. Any help is much appreciated.

  • Combined Likelihood Models

    - by Lukas Vermeer
    In a series of posts on this blog we have already described a flexible approach to recording events, a technique to create analytical models for reporting, a method that uses the same principles to generate extremely powerful facet based predictions and a waterfall strategy that can be used to blend multiple (possibly facet based) models for increased accuracy. This latest, and also last, addition to this sequence of increasing modeling complexity will illustrate an advanced approach to amalgamate models, taking us to a whole new level of predictive modeling and analytical insights; combination models predicting likelihoods using multiple child models. The method described here is far from trivial. We therefore would not recommend you apply these techniques in an initial implementation of Oracle Real-Time Decisions. In most cases, basic RTD models or the approaches described before will provide more than enough predictive accuracy and analytical insight. The following is intended as an example of how more advanced models could be constructed if implementation results warrant the increased implementation and design effort. Keep implemented statistics simple! Combining likelihoods Because facet based predictions are based on metadata attributes of the choices selected, it is possible to generate such predictions for more than one attribute of a choice. We can predict the likelihood of acceptance for a particular product based on the product category (e.g. ‘toys’), as well as based on the color of the product (e.g. ‘pink’). Of course, these two predictions may be completely different (the customer may well prefer toys, but dislike pink products) and we will have to somehow combine these two separate predictions to determine an overall likelihood of acceptance for the choice. Perhaps the simplest way to combine multiple predicted likelihoods into one is to calculate the average (or perhaps maximum or minimum) likelihood. However, this would completely forgo the fact that some facets may have a far more pronounced effect on the overall likelihood than others (e.g. customers may consider the product category more important than its color). We could opt for calculating some sort of weighted average, but this would require us to specify up front the relative importance of the different facets involved. This approach would also be unresponsive to changing consumer behavior in these preferences (e.g. product price bracket may become more important to consumers as a result of economic shifts). Preferably, we would want Oracle Real-Time Decisions to learn, act upon and tell us about, the correlations between the different facet models and the overall likelihood of acceptance. This additional level of predictive modeling, where a single supermodel (no pun intended) combines the output of several (facet based) models into a single prediction, is what we call a combined likelihood model. Facet Based Scores As an example, we have implemented three different facet based models (as described earlier) in a simple RTD inline service. These models will allow us to generate predictions for likelihood of acceptance for each product based on three different metadata fields: Category, Price Bracket and Product Color. We will use an Analytical Scores entity to store these different scores so we can easily pass them between different functions. A simple function, creatively named Compute Analytical Scores, will compute for each choice the different facet scores and return an Analytical Scores entity that is stored on the choice itself. For each score, a choice attribute referring to this entity is also added to be returned to the client to facilitate testing. One Offer To Predict Them All In order to combine the different facet based predictions into one single likelihood for each product, we will need a supermodel which can predict the likelihood of acceptance, based on the outcomes of the facet models. This model will not need to consider any of the attributes of the session, because they are already represented in the outcomes of the underlying facet models. For the same reason, the supermodel will not need to learn separately for each product, because the specific combination of facets for this product are also already represented in the output of the underlying models. In other words, instead of learning how session attributes influence acceptance of a particular product, we will learn how the outcomes of facet based models for a particular product influence acceptance at a higher level. We will therefore be using a single All Offers choice to represent all offers in our combined likelihood predictions. This choice has no attribute values configured, no scores and not a single eligibility rule; nor is it ever intended to be returned to a client. The All Offers choice is to be used exclusively by the Combined Likelihood Acceptance model to predict the likelihood of acceptance for all choices; based solely on the output of the facet based models defined earlier. The Switcheroo In Oracle Real-Time Decisions, models can only learn based on attributes stored on the session. Therefore, just before generating a combined prediction for a given choice, we will temporarily copy the facet based scores—stored on the choice earlier as an Analytical Scores entity—to the session. The code for the Predict Combined Likelihood Event function is outlined below. // set session attribute to contain facet based scores. // (this is the only input for the combined model) session().setAnalyticalScores(choice.getAnalyticalScores); // predict likelihood of acceptance for All Offers choice. CombinedLikelihoodChoice c = CombinedLikelihood.getChoice("AllOffers"); Double la = CombinedLikelihoodAcceptance.getChoiceEventLikelihoods(c, "Accepted"); // clear session attribute of facet based scores. session().setAnalyticalScores(null); // return likelihood. return la; This sleight of hand will allow the Combined Likelihood Acceptance model to predict the likelihood of acceptance for the All Offers choice using these choice specific scores. After the prediction is made, we will clear the Analytical Scores session attribute to ensure it does not pollute any of the other (facet) models. To guarantee our combined likelihood model will learn based on the facet based scores—and is not distracted by the other session attributes—we will configure the model to exclude any other inputs, save for the instance of the Analytical Scores session attribute, on the model attributes tab. Recording Events In order for the combined likelihood model to learn correctly, we must ensure that the Analytical Scores session attribute is set correctly at the moment RTD records any events related to a particular choice. We apply essentially the same switching technique as before in a Record Combined Likelihood Event function. // set session attribute to contain facet based scores // (this is the only input for the combined model). session().setAnalyticalScores(choice.getAnalyticalScores); // record input event against All Offers choice. CombinedLikelihood.getChoice("AllOffers").recordEvent(event); // force learn at this moment using the Internal Dock entry point. Application.getPredictor().learn(InternalLearn.modelArray, session(), session(), Application.currentTimeMillis()); // clear session attribute of facet based scores. session().setAnalyticalScores(null); In this example, Internal Learn is a special informant configured as the learn location for the combined likelihood model. The informant itself has no particular configuration and does nothing in itself; it is used only to force the model to learn at the exact instant we have set the Analytical Scores session attribute to the correct values. Reporting Results After running a few thousand (artificially skewed) simulated sessions on our ILS, the Decision Center reporting shows some interesting results. In this case, these results reflect perfectly the bias we ourselves had introduced in our tests. In practice, we would obviously use a wider range of customer attributes and expect to see some more unexpected outcomes. The facetted model for categories has clearly picked up on the that fact our simulated youngsters have little interest in purchasing the one red-hot vehicle our ILS had on offer. Also, it would seem that customer age is an excellent predictor for the acceptance of pink products. Looking at the key drivers for the All Offers choice we can see the relative importance of the different facets to the prediction of overall likelihood. The comparative importance of the category facet for overall prediction might, in part, be explained by the clear preference of younger customers for toys over other product types; as evident from the report on the predictiveness of customer age for offer category acceptance. Conclusion Oracle Real-Time Decisions' flexible decisioning framework allows for the construction of exceptionally elaborate prediction models that facilitate powerful targeting, but nonetheless provide insightful reporting. Although few customers will have a direct need for such a sophisticated solution architecture, it is encouraging to see that this lies within the realm of the possible with RTD; and this with limited configuration and customization required. There are obviously numerous other ways in which the predictive and reporting capabilities of Oracle Real-Time Decisions can be expanded upon to tailor to individual customers needs. We will not be able to elaborate on them all on this blog; and finding the right approach for any given problem is often more difficult than implementing the solution. Nevertheless, we hope that these last few posts have given you enough of an understanding of the power of the RTD framework and its models; so that you can take some of these ideas and improve upon your own strategy. As always, if you have any questions about the above—or any Oracle Real-Time Decisions design challenges you might face—please do not hesitate to contact us; via the comments below, social media or directly at Oracle. We are completely multi-channel and would be more than glad to help. :-)

  • Is there any evidence that drugs can actually help programmers produce "better" code? [closed]

    - by sytycs
    I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Also a quote from that article: He was hardly alone among computer scientists in his appreciation of hallucinogenics and their capacity to liberate human thought from the prison of the mind. Now I'm wondering if there's any evidence to support the theory that drugs can help make a "better" programmer. Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a well-known programming concept or piece of code which originated from people who were on drugs? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

  • Developing a mobile application, how to show help if it contains too much data?

    - by MobileDev123
    I am developing a mobile application which has many functionality, and I am pretty sure that the design will confuse the user about how to use some functionality so we decided to include some help as we can see them regularly in desktop applications, but later we found that the help text is too long. We don't think that one screen is enough to describe what a user can do. Moreover the project itself is subjected to evolve based on beta stage and user reports. After a lot of thinking and meetings we have decided three options to show the users what they can do. Create the website or blog, so we can let the users know what they can do with this application, the advantage is that it can provide us a good source of marketing, but for that they have to access the site while most part of the application can be used while being offline in earlier versions. Create a section in the application called demos to show the same thing locally, but we are afraid that it will increase the size, that we think can be avoided (and we are planning to avoid if there is any option) Show popups, but we discarded this thinking that pop ups annoys user no matter what the platform is. I want to know from community that which option will you choose, we are also open to accept other ideas if you have.

  • Oracle Delivers Special Recognition for Specialized Partners

    - by michaela.seika(at)oracle.com
    Since announcing Oracle PartnerNetwork Specialized (OPN Specialized) in October 2009, Oracle has been focused on building a program that first enables solution providers to become highly skilled Oracle partners who deliver value to customers and that then recognizes and rewards their achievements in a meaningful way. Today the company unveiled new benefits reserved for partners who have achieved one or more of the over 50 specializations currently available. The benefits demonstrate Oracle's commitment to showcase these valued partners to three key audiences: customers, other partners, and Oracle employees.With today's launch of www.oracle.com/specialized Oracle has taken what IDC believes is a first of its kind approach to putting top partners front and center with customers and prospects. While most vendors offer a business partner finder tool on their website none has gone as far as Oracle with the creation of this new site dedicated to the promotion of Specialized Partners. The tag lines - "Recognized by Oracle, Preferred by Customers" and "Specialized. Recognized. Preferred." gets right to the point - these are the solution providers with which customers should choose to engage. The contents of the page offer multiple proof points to justify the marketing phrases.One of the benefits Oracle offers its Specialized Partners is video creation and placement. While Oracle works with partners to create informal or "guerilla" videos which often are placed on YouTube to generate awareness and buzz, the company also produces professional videos for its partners. The greatest value the partner receives from this benefit isn't the non-trivial production costs that Oracle covers but instead the prominent exposure Oracle gives the finished product. Partner videos are featured on www.oracle.com/specialized, used as part of monthly OPN Specialized Partners monthly webcasts, placed on a customer facing website, the Oracle Media Network, which includes several partner sites such as PartnerCast. A solution provider gains a great deal of credibility when they can send a prospect to an Oracle website where they are featured. Read the full article here.

  • SQLRally Nordic gets underway

    - by Rob Farley
    PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

From Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported), and according to the steps guide: 1 - We create a partition from Win8 (70 GB) from the own win8 program. 2 - Confirm-SecureBootUEFI=True. 3 - From Win8, shift + Restart and from special menu we selected the UEFI Firmware Setting. 4 - From BIOS Option: ------Option 1) Disable Secure Boot. ------Option 2) Disable UEFI (Not Available) from Option 1: Three ways is available. With Secure Boot enable - We can't even boot ubuntu. A red windows saying Soft unproper signed. With Secure Boot disable - and this config in boot device order: ----1: UEFI: USB ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu then a black windows appears and nothing happens. The same result if install ubuntu is selected. With Secure Boot disable - and this config in boot device order: ----1: USB (No UEFI) ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu, - Ubuntu boots and we can install it even. 5 - Rebooting and just changing the boot order as ----1: Ubuntu [] ----2: Windows Boot Manger ----3: Others then nothings happens. 6 - Booting from LiveUSB again and, as per instructed, making Boot-Repair (A warning windows: Ubuntu is working in legacy mode.). 7 - Saving changes and rebooting, Grub works but selecting Ubuntu, a black windows appears and nothing happens. Selecting Win8, Win8 boots and works. Untill now we can't make the ubuntu installation. Any suggestion will be welcomed. kind regards and thanks in advance.

  • GetContactList stops reporting collisions on welded bodies

    - by Henrique Jung
    I have some strange problem with my game which uses Box2D as physics engine and I'm out of ideas on what I can do to solve it. My game is a class assignment where I need to build a simple game where the main character moves in a 2D environment while square blocks comes from below him. Each time a collision occurs, that block is attached to the character using a weld joint, when three blocks of the same colors are together, they annihilate themselves(an effect similar to Bejeweled). I'm using a recursive function to iterate through all the attached blocks of a given block to see if there are enough blocks for them to be deleted. I'm using GetContactList function to iterate through the list of contacts to see which blocks are adjacent to each other. The results are quite disappointing, the blocks only get annihilated in few cases. After a lot of debugging, I found the issue, but I still don't know how to solve. My issue is: after some time, GetContactList STOPS returning contacts (return NULL) to blocks that were already attached for some time. I spent some time reading the Box2D manual as well as some tutorials and still didn't find any clue of what is happening. Below there's some simplified version of the code that I wrote. for(int a = 0; a < blocksList.size(); a++) { blocksList[a].BuildConnections(); } And on BuildConnections b2ContactEdge* edge = body->GetContactList(); while(edge != NULL) { if (long_check_to_see_if_there's_a_block_nearby) { // add itself to the list to be anihilated globalList.push_back(this); //if there's, call BuildConnections again on the adjacent block adjacentBody->GetUserData()->BuildConnections; } edge = edge->next; } I know that there's another issue related to circular inclusions, but I fairly sure that this problem isn't causing the problem with the collisions. You can download my entire code from this page if you'd like http://code.google.com/p/fellz/source/list

  • Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

    - by Eric Nelson
    Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

  • Dynamic endpoint binding in Oracle SOA Suite by Cattle Crew

    - by JuergenKress
    Why is dynamic endpoint binding needed? Sometimes a BPEL process instance has to determine at run-time which implementation of a web service interface is to be called. We’ll show you how to achieve that using dynamic endpoint binding. Let’s imagine the following scenario: we’re running a car rental agency called RYLC (Rent Your Legacy Car) which operates different locations. The process of renting a car is basically identical for all locations except for the determination which cars are currently available. This is depicted in the following diagram: There are three different implementations of the GetAvailableCars service. But how can we achieve calling them dynamically at run-time using Oracle SOA Suite? How to dynamically set the service endpoint There are just a couple of implementation steps we need to perform to enable dynamic endpoint binding: create a new SOA project in JDeveloper add a CarRental BPEL process add an external reference to the GetAvailableCars service within the composite create a DVM file containing the URI’s by which the services for the different locations can be accessed set the endpointURI property on the Invoke component calling the GetAvailableCars service (value is taken from the DVM file) Read the complete article here.

  • Language parsing to find important words

    - by Matt Huggins
    I'm looking for some input and theory on how to approach a lexical topic. Let's say I have a collection of strings, which may just be one sentence or potentially multiple sentences. I'd like to parse these strings to and rip out the most important words, perhaps with a score that denotes how likely the word is to be important. Let's look at a few examples of what I mean. Example #1: "I really want a Keurig, but I can't afford one!" This is a very basic example, just one sentence. As a human, I can easily see that "Keurig" is the most important word here. Also, "afford" is relatively important, though it's clearly not the primary point of the sentence. The word "I" appears twice, but it is not important at all since it doesn't really tell us any information. I might expect to see a hash of word/scores something like this: "Keurig" => 0.9 "afford" => 0.4 "want" => 0.2 "really" => 0.1 etc... Example #2: "Just had one of the best swimming practices of my life. Hopefully I can maintain my times come the competition. If only I had remembered to take of my non-waterproof watch." This example has multiple sentences, so there will be more important words throughout. Without repeating the point exercise from example #1, I would probably expect to see two or three really important words come out of this: "swimming" (or "swimming practice"), "competition", & "watch" (or "waterproof watch" or "non-waterproof watch" depending on how the hyphen is handled). Given a couple examples like this, how would you go about doing something similar? Are there any existing (open source) libraries or algorithms in programming that already do this?

  • Solutions for Project management [closed]

    - by user14416
    The team consists of 3 people. The method of development is Scrum. The language of the project is C++. The project will be under the control of the git system. The start up budget is 0. The following things have to be chosen: Build and Version Numbering Project documentation ( file with the most common info for current stage of the project, which will be changed every time the new version or subversion of the project emerges ) Project management tool ( like Trac or Redmine, I cannot use them, because there is no hosting ) Code documentation ( I consider Doxygen ) The following questions have arisen: What can you add to the above list of the main solutions for project management in the described project? One of three project participants has linux os (No MS Office), one has Windows and MS Office (does not want to use Libre or Open Office), one has Windows, but does not have MS Office. What formats, tools can u suggest using for project documentation? The variant of using online wiki does not fit, it must be files. OneNote mb is a good tool for project management, but because of the reason mentioned above it is not possible. What can you advise? Offer a system for Build and Version Numbering.

  • How can I rank teams based off of head to head wins/losses

    - by TMP
    I'm trying to write an algorithm (specifically in Ruby) that will rank teams based on their record against each other. If a team A and team B have won the same amount of games against each other, then it goes down to point differentials. Here's an example: A beat B two times B beats C one time A beats D three times C bests D two times D beats C one time B beats A one time Which sort of reduces to A[B] = 2 B[C] = 1 A[D] = 3 C[D] = 2 D[C] = 1 B[A] = 1 Which sort of reduces to A[B] = 1 B[C] = 1 A[D] = 3 C[D] = 1 D[C] = -1 B[A] = -1 Which is about how far I've got I think the results of this specific algorithm would be: A, B, C, D But I'm stuck on how to transition from my nested hash-like structure to the results. My psuedo-code is as follows (I can post my ruby code too if someone wants): For each game(g): hash[g.winner][g.loser] += 1 That leaves hash as the first reduction above hash2 = clone of hash For each key(winner), value(losers hash) in hash: For each key(loser), value(losses against winner): hash2[loser][winner] -= losses Which leaves hash2 as the second reduction Feel free to as me question or edit this to be more clear, I'm not sure of how to put it in a very eloquent way. Thanks!

  • User Acceptance Testing Defect Classification when developing for an outside client

    - by DannyC
    I am involved in a large development project in which we (a very small start up) are developing for an outside client (a very large company). We recently received their first output from UAT testing of a fairly small iteration, which listed 12 'defects', triaged into three categories : Low, Medium and High. The issue we have is around whether everything in this list should be recorded as a 'defect' - some of the issues they found would be better described as refinements, or even 'nice-to-haves', and some we think are not defects at all. They client's QA lead says that it is standard for them to label every issues they identify as a defect, however, we are a bit uncomfortable about this. Whilst the relationship is good, we don't see a huge problem with this, but we are concerned that, if the relationship suffers in the future, these lists of 'defects' could prove costly for us. We don't want to come across as being difficult, or taking things too personally here, and we are happy to make all of the changes identified, however we are a bit concerned especially as there is a uneven power balance at play in our relationship. Are we being paranoid here? Or could we be setting ourselves up for problems down the line by agreeing to this classification?
