  • Hack Apart a Highlighter to Create UV-Reactive Flowers [Science]

    - by ETC
    College students have long been hacking apart highlighters to create glowing bottles of booze to line their dorm room walls. Far more interesting, however, is the application of the hack to flowers. Many of you may remember a science class experiment from years gone by where in you put food coloring in a beaker and then some freshly cut white flowers; returning to the experiment a day later yielded flowers colored to match the dye you added. This little experiment relies on the same technique, only instead of blue food coloring the flowers suck up UV-reactive highlighter dye. Check out the video below to see the experiment in action: Have a fun science experiment to share? Let’s hear about it in the comments.

  • Bad style programming, am I pretending too much?

    - by Luca
    I realized to work in an office with a quite bad code base. The base library implemented in years and years is quite limited, and most of that code is, honestly, horrible. Projects developed in the office are very large. Fine. I could define me a "perfectionist" (but often I'm not), and I thought to refactor an application (really a portion), which need a new (complex) feature. But, today, I really realized that it's not possible to refactor that application modules with a reasonable time (say, 24/26 hours, respect the avaialable time for the task, which is 160 hours). I'm talking about (I am a bit ashamed to say) name collisions, large and frequent cut & paste code, horrible and misleading naming, makefiles without dependencies (!), application login is spread randomly across many different sources, dead code, variable aliasing, no assertion, no documentation, very long source files, bad/incomplete include file definition, (this is emblematic!) very frequent extern declaration of variables and functions, ... I'm sure to continue ... buffer overflows because sprintf, indentation (!), spacing, non existent const modifier usage. I would say that every source line was written quite randomly when needed, without keeping in mind some design (at least, the obvious one). (Am I in hell?) The problem arises when the application is developed by a colleague of mine. I felt very frustrated. So, I decided to expose the "situation" to my colleague; at the end, that was a bad idea. He is justified in saying that "the application was developed in haste, so it is natural that it is written vaguely; you are wasting time to think and implement an elegant implementation" .... I'm asking too much from my colleague to write readable code, which is managed and documented? I expect too much in not having to read thousands of lines of code to understand how a particular logic?

  • Should programmers itemize testing for projects? [on hold]

    - by Patton77
    I recently hired a programming team to do a port of my iPad app to the iPhone and Android platforms. Now, in a separate contract, I am asking them to implement a bunch of tips on how to play the app, similar like you would find in Candy Crush or Cut the Rope. They want to charge 12 hours @ $35/hr for the "Testing all of the Tips", telling me that normally it would take them more than 25 hours but that they will 'bear the difference'. I am not familiar with this level of itemization, but maybe it's a new practice? I am used to devs doing their own quality control, and then having a testing/acceptance period. They are using Cocos 2D-X, and they say that the tips going to multiple platforms makes all of the hours jack up. I feel like they might be overcharging, and it's difficult for me to know because it's kind of like with a mechanic. "It took us 5 hours to replace the radiator". How can you dispute that? It seems to me that most of you would charge for the work but NOT for hours that you are 'testing'. Am I missing something? Thanks for any help and advice you can give!

  • Watson Ties Against Human Jeopardy Opponents

    - by ETC
    In January we showed you a video of Waton in a practice round against Jeopardy champions Ken Jennings and Brad Rutter. Last night they squared off in a real round of Jeopardy with Watson in a tie with Rutter. Watson held his own against the two champions leveraging the 90 IBM Power 750 servers, 2,880 processors, and the 16TB of memory driving him to his full advantage. It was impressive to watch the round unfold and to see where Watson shined and where he faltered. Check out the video below to footage of Watson in training and then in action on Jeopardy. Pay special attention to the things that trip him up. Watson answers cut and dry questions with absolute lighting speed but stumbles when it comes to nuances in language–like finis vs. terminus in the train question that Jennings answered correctly.

  • Should programmers itemize testing in testing? [on hold]

  • Developing professionally for iOS, Android and web - an insight

    - by Scott Roberts
    This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps? I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin. Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps? I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along. So any cross platform developers out there? Do companies have different teams for different platforms? Any insight would just help me get my head together. Hopefully this question makes sense.

  • How do I Delete a View? How do I Create a View?

    - by Paula DiTallo
    Before I create views, I generally work out what I want to retrieve in my SELECT statement ahead of time so I'll just  have to cut and  paste the query. The example below is done  in T-SQL/Sybase format, however for Oracle and MySQL, just  place a semi-colon ';' at the end of your statement and remove the  'GO' command.          To drop (delete) an existing view: DROP VIEW vw_rpt_metroBestCustomers GO To create a view: CREATE VIEW vw_rpt_metroBestCustomers ( CustomerName,    OfficeNum,    City,    StateOrProv,    Country,    ZipCode   ) AS SELECT a.FirstName + ', ' + a.LastName,           b.OfficePhoneNum,           c.City,           c.StateOrProvAbbr,           c.Country,           c.PostalCode     FROM Customer a,          CustLocAssoc x,          CustContactAssoc y,          Location c,          Contact b     WHERE a.CustID = x.CustID       AND a.CustID = y.CustID       AND y.ContactID = b.ContactID       AND x.LocID = c.LocID       AND a.LoyaltyMedian > 85.5 GO        I frequently rename columns when developing views to makeit easier for simple, text-based reporting--however, renamingthe columns isn't necessary.The create view statement above could have been writtenas follows:CREATE VIEW vw_rpt_metroBestCustomersAS (SELECT a.FirstName + ', ' + a.LastName, b.OfficePhoneNum, c.City, c.StateOrProvAbbr, c.Country, c.PostalCode FROM Customer a, CustLocAssoc x, CustContactAssoc y, Location c, Contact b WHERE a.CustID = x.CustID AND a.CustID = y.CustID AND y.ContactID = b.ContactID AND x.LocID = c.LocID AND a.LoyaltyMedian > 85.5 )GO

  • Who writes the words? A rant with graphs.

    - by Roger Hart
    If you read my rant, you'll know that I'm getting a bit of a bee in my bonnet about user interface text. But rather than just yelling about the way the world should be (short version: no UI text would suck), it seemed prudent to actually gather some data. Rachel Potts has made an excellent first foray, by conducting a series of interviews across organizations about how they write user interface text. You can read Rachel's write up here. She presents the facts as she found them, and doesn't editorialise. The result is insightful, but impartial isn't really my style. So here's a rant with graphs. My method, and how it sucked I sent out a short survey. Survey design is one of my hobby-horses, and since some smartarse in the comments will mention it if I don't, I'll step up and confess: I did not design this one well. It was potentially ambiguous, implicitly excluded people, and since I only really advertised it on Twitter and a couple of mailing lists the sample will be chock full of biases. Regardless, these were the questions: What do you do? Select the option that best describes your role What kind of software does your organization make? (optional) In your organization, who writes the text on your software user interfaces? (for example: button names, static text, tooltips, and so on) Tick all that apply. In your organization who is responsible for user interface text? Who "owns" it? The most glaring issue (apart from question 3 being a bit broken) was that I didn't make it clear that I was asking about applications. Desktop, mobile, or web, I wouldn't have minded. In fact, it might have been interesting to categorize and compare. But a few respondents commented on the seeming lack of relevance, since they didn't really make software. There were some other issues too. It wasn't the best survey. So, you know, pinch of salt time with what follows. Despite this, there were 100 or so respondents. This post covers the overview, and you can look at the raw data in this spreadsheet What did people do? Boring graph number one: I wasn't expecting that. Given I pimped the survey on twitter and a couple of Tech Comms discussion lists, I was more banking on and even Content Strategy/Tech Comms split. What the "Others" specified: Three people chipped in with Technical Writer. Author, apparently, doesn't cut it. There's a "nobody reads the instructions" joke in there somewhere, I'm sure. There were a couple of hybrid roles, including Tech Comms and Testing, which sounds gruelling and thankless. There was also, an Intranet Manager, a Creative Director, a Consultant, a CTO, an Information Architect, and a Translator. That's a pretty healthy slice through the industry. Who wrote UI text? Boring graph number two: Annoyingly, I made this a "tick all that apply" question, so I can't make crude and inflammatory generalizations about percentages. This is more about who gets involved in user interface wording. So don't panic about the number of developers writing UI text. First off, it just means they're involved. Second, they might be good at it. What? It could happen. Ours are involved - they write a placeholder and flag it to me for changes. Sometimes I don't make any. It's also not surprising that there's so much UX in the mix. Some of that will be people taking care, and crafting an understandable interface. Some of it will be whatever text goes on the wireframe making it into production. I'm going to assume that's what happened at eBay, when their iPhone app purportedly shipped with the placeholder text "Some crappy content goes here". Ahem. Listing all 17 "other" responses would make this post lengthy indeed, but you can read them in the raw data spreadsheet. The award for the approach that sounds the most like a good idea yet carries the highest risk of ending badly goes to whoever offered up "External agencies using focus groups". If you're reading this, and that actually works, leave a comment. I'm fascinated. Who owned UI text Stop. Bar chart time: Wow. Let's cut to the chase, and by "chase", I mean those inflammatory generalizations I was talking about: In around 60% of cases the person responsible for user interface text probably lacks the relevant expertise. Even in the categories I count as being likely to have relevant skills (Marketing Copywriters, Content Strategists, Technical Authors, and User Experience Designers) there's a case for each role being unsuited, as you'll see in Rachel's blog post So it's not as simple as my headline. Does that mean that you personally, Mr Developer reading this, write bad button names? Of course not. I know nothing about you. It rather implies that as a category, the majority of people looking after UI text have neither communication nor user experience as their primary skill set, and as such will probably only be good at this by happy accident. I don't have a way of measuring those frequency of those accidents. What the Others specified: I don't know who owns it. I assume the project manager is responsible. "copywriters" when they wish to annoy me. the client's web maintenance person, often PR or MarComm That last one chills me to the bone. Still, at least nobody said "the work experience kid". You can see the rest in the spreadsheet. My overwhelming impression here is of user interface text as an unloved afterthought. There were fewer "nobody" responses than I expected, and a much broader split. But the relative predominance of developers owning and writing UI text suggests to me that organizations don't see it as something worth dedicating attention to. If true, that's bothersome. Because the words on the screen, particularly the names of things, are fundamental to the ability to understand an use software. It's also fascinating that Technical Authors and Content Strategists are neck and neck. For such a nascent discipline, Content Strategy appears to have made a mark on software development. Or my sample is skewed. But it feels like a bit of validation for my rant: Content Strategy is eating Tech Comms' lunch. That's not a bad thing. Well, not if the UI text is getting done well. And that's the caveat to this whole post. I couldn't care less who writes UI text, provided they consider the user and don't suck at it. I care that it may be falling by default to people poorly disposed to doing it right. And I care about that because so much user interface text sucks. The most interesting question Was one I forgot to ask. It's this: Does your organization have technical authors/writers? Like a lot of survey data, that doesn't tell you much on its own. But once we get a bit dimensional, it become more interesting. So taken with the other questions, this would have let me find out what I really want to know: What proportion of organizations have Tech Comms professionals but don't use them for UI text? Who writes UI text in their place? Why this happens? It's possible (feasible is another matter) that hundreds of companies have tech authors who don't work on user interfaces because they've empirically discovered that someone else, say the Marketing Copywriter, is better at it. And once we've all finished laughing, I'll point out that I've met plenty of tech authors who just aren't used to thinking about users at the point of need in the way UI text and embedded user assistance require. If you've got what I regard, perhaps unfairly, as the bad kind of tech author - the old-school kind with the thousand-page pdf and the grammar obsession - if you've got one of those then you probably are better off getting the UX folk or the copywriters to do your UI text. At the very least, they'll derive terminology from user research.

  • Rotation of bitmap using a frame by frame animation

    - by pengume
    Hey every one I know this has probably been asked a ton of times but I just wanted to clarify if I am approaching this correctly, since I ran into some problems rotating a bitmap. So basically I have one large bitmap that has four frames drawn on it and I only draw one at a time by looping through the bitmap by increments to animate walking. I can get the bitmap to rotate correctly when it is not moving but once the animation starts it starts to cut off alot of the image and sometimes becomes very fuzzy. I have tried public void draw(Canvas canvas,int pointerX, int pointerY) { Matrix m; if (setRotation){ // canvas.save(); m = new Matrix(); m.reset(); // spriteWidth and spriteHeight are for just the current frame showed m.setTranslate(spriteWidth / 2, spriteHeight / 2); //get and set rotation for ninja based off of joystick m.preRotate((float) GameControls.getRotation()); //create the rotated bitmap flipedSprite = Bitmap.createBitmap(bitmap , 0, 0,bitmap.getWidth(),bitmap.getHeight() , m, true); //set new bitmap to rotated ninja setBitmap(flipedSprite); // canvas.restore(); Log.d("Ninja View", "angle of rotation= " +(float) GameControls.getRotation()); setRotation = false; } And then the Draw Method here // create the destination rectangle for the ninjas current animation frame // pointerX and pointerY are from the joystick moving the ninja around destRect = new Rect(pointerX, pointerY, pointerX + spriteWidth, pointerY + spriteHeight); canvas.drawBitmap(bitmap, getSourceRect(), destRect, null); The animation is four frames long and gets incremented by 66 (the size of one of the frames on the bitmap) for every frame and then back to 0 at the end of the loop.

  • Which iPhone ad API has produced the highest revenue for you?

    - by Kyle Humfeld
    This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

  • Good Freelance models for web developers

    - by Matthew Underwood
    I am a web developer with four years of experience in PHP, MYSQL and experience in Javascript etc. One day I hope to develop a freelance career in web development. Areas of freelance that I am thinking of going towards includes Wordpress, Magento development along with bespoke applications. I am also thinking of doing some consultancy work for clients and businesses when I build up some more experience and technical knowledge. I want to offer a web development service to potential clients that plays on my strengths in what I know but most importantly has a market. Web development can cover so many subjects that its difficult to pick out the areas that have demand. I am also curious to find out if web developers offer services that bring in a monthly income e.g application maintenance or database maintenance? Is there a market for certain areas like WordPress plugins or bespoke applications? Are there certain things to avoid because of work duration, unrealistic client expectations or the fact that its impossible to find a market for it? As professional and experienced freelance web developers have you learned some important do's and don'ts? Is there certain services that the majority of web developers offer because its in high demand? This is the one area of web development freelancing that I cant get my head around. I know there is never a definitive answer but there must be some good practises and general consensus on this subject. Web designers design websites they offer a lump sum and get paid monthly sometimes to add new content, PPC and SEO consultants market sites to the top this will involve monthly payments, web development doesn’t seem so clear cut.

    Silverlight/Expression 4 Books! I recently stumbled upon a post asking, “What is the best book on Silverlight 4?” In the age of the internet, it can be hard for anyone searching for a good book to actually find it. I have read a few Silverlight 4/Expression books in 2010 and decided to post the “best of” collection. Instead of reading multiple books, you can cut your list down to whatever category that you fit in. With Silverlight 5 coming soon, now is the time to get up to speed with what Silverlight 4 can offer. Be sure to read the full review at the bottom of each section. For the “Beginner” Silverlight Developer: Both of these books contains very simple applications and will get you started very fast. and Book Review: Microsoft Silverlight 4 Step by Step For the guy/gal that wants to “Master” Expression Blend 4: This is a hands-on kind of book. Victor get you started early on with some sample application and quickly deep dives into Storyboard and other Animations. If you want to learn Blend 4 then this is the place to start. Book Review: Foundation Expression Blend 4 by Victor Gaudioso If you are aiming to learn more about the Business side of Silverlight then check out the following two books: and Finally, For the Silverlight 4 guy/gal that wants to “Master” Silverlight 4, it really boils down to the following two books: and   Book Review: Silverlight 4 Unleashed by Laurent Bugnion Book Review: Silverlight 4 in Action by Pete Brown I can’t describe how much that I’ve actually learned from both of these books. I would also recommend you read these books if you are preparing for your Silverlight 4 Certification.

  • Using OData to get Mix10 files

    - by Jon Dalberg
    There has been a lot of talk around OData lately (go to odata.org for more information) and I wanted to get all the videos from Mix ‘10: two great tastes that taste great together. Luckily, Mix has exposed the ‘10 sessions via OData at http://api.visitmix.com/OData.svc, now all I have to do is slap together a bit of code to fetch the videos. Step 1 (cut a hole in the box) Create a new console application and add a new service reference. Step 2 (put your junk in the box) Write a smidgen of code: 1: static void Main(string[] args) 2: { 3: var mix = new Mix.EventEntities(new Uri("http://api.visitmix.com/OData.svc")); 4:   5: var files = from f in mix.Files 6: where f.TypeName == "WMV" 7: select f; 8:   9: var web = new WebClient(); 10: 11: var myVideos = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "Mix10"); 12:   13: Directory.CreateDirectory(myVideos); 14:   15: files.ToList().ForEach(f => { 16: var fileName = new Uri(f.Url).Segments.Last(); 17: Console.WriteLine(f.Url); 18: web.DownloadFile(f.Url, Path.Combine(myVideos, fileName)); 19: }); 20: } Step 3 (have her open the box) Compile and run. As you can see, the client reference created for the OData service handles almost everything for me. Yeah, I know there is some batch file to download the files, but it relies on cUrl being on the machine – and I wanted an excuse to work with an OData service. Enjoy!

  • Does Unity's "Transparent Bumped Specular" translate to "semi-shiny must be semi-transparent"?

    - by Shivan Dragon
    Unity's documentation for the "Transparent Bumped Specular" shader/material-type is simply a concatenation of each of the descriptions for its Transparent and Specular Shaders (and also Bumped, but that doesn't apply to the question): Transparent Properties This shader can make mesh geometry partially or fully transparent by reading the alpha channel of the main texture. In the alpha, 0 (black) is completely transparent while 255 (white) is completely opaque. If your main texture does not have an alpha channel, the object will appear completely opaque. (...) Specular Properties (...) Additionally, the alpha channel of the main texture acts as a Specular Map (sometimes called "gloss map"), defining which areas of the object are more reflective than others. Black areas of the alpha will be zero specular reflection, while white areas will be full specular reflection. To me this translates to: I have a mesh representig a car tire The texture need to be very shiny on the rims parts, and almost not shiny at all for the rubber parts Also since the rim is really complex, (with like cut-out decoretions and such), I will not build that into the mesh, but fake it with transparency in the texture I can't do all this using Unity's "Transparent Bumped Specular" shader, because the "rubber" part of the texture will become semi transparent due to me painting the alpha channel dark-grey (because I want it to also be less shiny). Is this correct? If not, how can I make this work?

  • Hill International Wins Oracle Eco-Enterprise Innovation Award

    - by Evelyn Neumayr
    In my last blog entry, I discussed Oracle’s Eco-Enterprise Innovation Award, part of the Oracle Excellence awards. Nominations for this year’s awards are due July 17. These awards are presented to organizations that use Oracle products to reduce their environmental footprint while improving their operational efficiency. One of last year’s winners was Hill International. Engineering News-Record magazine recently ranked Hill as the eighth-largest construction management firm in the United States. Hill International was able to streamline its forecasting and improve its visibility into its construction projects’ productivity and profitability using Oracle Primavera. They also implemented Oracle Hyperion Financial Management to standardize its financial reporting and forecasting processes and support its decision-making. With Oracle, Hill gained visibility into the true productivity of each project and cut its financial reporting cycle time from two weeks to one. The company also used the data generated to support new construction project proposals and determine the profitability of potential projects. Hill International realized significant cost savings and reduced its environmental impact on its US$400 million Comcast Center construction project in Philadelphia by centralizing its data storage, reducing paper usage, and maximizing project efficiency. It also leveraged the increased visibility offered by the Oracle solutions to make more environmentally-sound business decisions regarding on-site demolition, re-use of previous structures, green design of new facilities, procurement, and materials usage. See more about Hill International and the other Eco-Enterprise Innovation award winners here.

  • Unexpected issues with SessionPageStatePersiste

    - by geekrutherford
    Several iterations ago I implemented the SessionPageStatePersister in an application as a way to cut down on the size of the hidden ViewState input on aspx pages.   At first it seemed utterly fantasic. The size of the ViewState appeared to be drastically reduced and the application did not appear to peform any slower than baseline.   Enter the iFrame &amp; user control. I added a user control which pings the web server every 20 seconds in order to show updated application information to the user (new messages, reports, etc.) After releasing this nifty little control into the QA environment I quickly began receiving emails from testers about "post back" related error messages which mostly centered around invalid ViewState exceptions.   At first I dismissed it as something related to all of the AJAX requests happening on the page and considered turning off page event validation. However, upon further investigation I came across the following article:   Things That You Should Watch Out For When Using SessionPageStatePersister   In this article the author specifically states:   If you application uses frames than each frame request will create a new session view state item and as before it will remove items when reaching the maximum, you come into a situation that one of the frames will probably loose it session view state because other frames did post backs.   Oh snap! That is precisely what I am doing. That combined with multiple users on the application equals dropped ViewStates!   The temporary fix has been to disable the use of the SessionPageStatePersister in my application. This results in a bloated hidden ViewState input, but the web server is no longer tasked with maintaing/retreiving it and the app. no longer loses ViewState information.

  • Implementing Light Volume Front Faces

    - by cubrman
    I recently read an article about light indexed deferred rendering from here: http://code.google.com/p/lightindexed-deferredrender/ It explains its ideas in a clear way, but there was one point that I failed to understand. It in fact is one of the most interesting ones, as it explains how to implement transparency with this approach: Typically when rendering light volumes in deferred rendering, only surfaces that intersect the light volume are marked and lit. This is generally accomplished by a “shadow volume like” technique of rendering back faces – incrementing stencil where depth is greater than – then rendering front faces and only accepting when depth is less than and stencil is not zero. By only rendering front faces where depth is less than, all future lookups by fragments in the forward rendering pass will get all possible lights that could hit the fragment. Can anyone explain how exactly you need to render only front faces? Another question is why do you need the front faces at all? Why can't we simply render all the lights and store the ones that overlap at this pixel in a texture? Does this approach serves as a cut-off plane to discard lights blocked by opaque geometry?

  • How lookaheads are propagated in "channel" method of building LALR parser?

    - by greenoldman
    The method is described in Dragon Book, however I read about it in ""Parsing Techniques" by D.Grune and C.J.H.Jacobs". I start from my understanding of building channels for NFA: channels are built once, they are like water channels with current you "drop" lookahead symbols in right places (sources) of the channel, and they propagate with "current" when symbol propagates, there are no barriers (the only sufficient things for propagation are presence of channel and direction/current); i.e. lookahead cannot just die out of the blue Is that right? If I am correct, then eof lookahead should be present in all states, because the source of it is the start production, and all other production states are reachable from start state. How the DFA is made out of this NFA is not perfectly clear for me -- the authors of the mentioned book write about preserving channels, but I see no purpose, if you propagated lookaheads. If the channels have to be preserved, are they cut off from the source if the DFA state does not include source NFA state? I assume no -- the channels still runs between DFA states, not only within given DFA state. In the effect eof should still be present in all items in all states. But when you take a look at DFA presented in book (pdf is from errata): DFA for LALR (fig. 9.34 in the book, p.301) you will see there are items without eof in lookahead. The grammar for this DFA is: S -> E E -> E - T E -> T T -> ( E ) T -> n So how it was computed, when eof was dropped, and on what condition? Update It is textual pdf, so two interesting states (in DFA; # is eof): State 1: S--- >•E[#] E--- >•E-T[#-] E--- >•T[#-] T--- >•n[#-] T--- >•(E)[#-] State 6: T--- >(•E)[#-)] E--- >•E-T[-)] E--- >•T[-)] T--- >•n[-)] T--- >•(E)[-)] Arc from 1 to 6 is labeled (.

  • Spotlight: How Scandinavia's Largest Nuclear Power Plant Increased Productivity and Reduced Costs wi

    - by [email protected]
    Ringhals nuclear power plant, which is part of the Vattenfall Group, is located about 60 km south-west of the beautiful coastal city of Gothenburg in Sweden. A deep concern to reduce environmental impact coupled with an effort to increase plant safety and operational efficiency have led to a recent surge in investments and initiatives around plant modification and plant optimization at Ringhals. A multitude of challenges were faced by the users in various groups that were involved in these projects. First, it was very difficult for users to easily access complex and layered asset and engineering information, which was critical to increased productivity and completing projects on time. Moreover, the 20 or so different solutions that were being used to view various document formats, not only resulted in collaboration complexity but also escalated IT administration costs and woes. Finally, there was a considerable non-engineering community comprising non-CAD specialists that needed easy access to plant data in an effort to minimize engineering disruption. Oracle's AutoVue significantly simplified the ability to efficiently view and use digital asset information by providing a standardized visualization solution for the enterprise. The key benefits achieved by Ringhals include: Increased productivity of plant optimization and plant modification by 3% Saved around $ 500 K annually Cut IT maintenance costs by 50% by using a single solution Reduced engineering disruption by allowing non-CAD users easy access to digital plant data The complete case-study can be found here
