  • Are closures with side-effects considered "functional style"?

    - by Giorgio
    Many modern programming languages support some concept of closure, i.e. of a piece of code (a block or a function) that Can be treated as a value, and therefore stored in a variable, passed around to different parts of the code, be defined in one part of a program and invoked in a totally different part of the same program. Can capture variables from the context in which it is defined, and access them when it is later invoked (possibly in a totally different context). Here is an example of a closure written in Scala: def filterList(xs: List[Int], lowerBound: Int): List[Int] = xs.filter(x => x >= lowerBound) The function literal x => x >= lowerBound contains the free variable lowerBound, which is closed (bound) by the argument of the function filterList that has the same name. The closure is passed to the library method filter, which can invoke it repeatedly as a normal function. I have been reading a lot of questions and answers on this site and, as far as I understand, the term closure is often automatically associated with functional programming and functional programming style. The definition of function programming on wikipedia reads: In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. and further on [...] in functional code, the output value of a function depends only on the arguments that are input to the function [...]. Eliminating side effects can make it much easier to understand and predict the behavior of a program, which is one of the key motivations for the development of functional programming. On the other hand, many closure constructs provided by programming languages allow a closure to capture non-local variables and change them when the closure is invoked, thus producing a side effect on the environment in which they were defined. In this case, closures implement the first idea of functional programming (functions are first-class entities that can be moved around like other values) but neglect the second idea (avoiding side-effects). Is this use of closures with side effects considered functional style or are closures considered a more general construct that can be used both for a functional and a non-functional programming style? Is there any literature on this topic? IMPORTANT NOTE I am not questioning the usefulness of side-effects or of having closures with side effects. Also, I am not interested in a discussion about the advantages / disadvantages of closures with or without side effects. I am only interested to know if using such closures is still considered functional style by the proponent of functional programming or if, on the contrary, their use is discouraged when using a functional style.

  • Which programming language to get into?

    - by user602479
    I'm ending my third term in a few weeks so I have some spare time coming up. I'd like to spend it seriously digging into programming. My problem: I'm not sure which language to begin with. Just to be clear, I don't want to start a language-y-compared-to-language-z discussion. There are a some other issues that play a major role. In my 5th term I'm going to be participating in a major practical course which will include either Java or C programming. It will take a lot of time and energy, as I found out while talking to a few students who passed the final exams (only 15% pass on their first try). Which practical course I will take is randomly decided. My skills so far are the absolute basics of Java and C programming. I know the different data types and how to handle them, objects, pointers, thread programming, etc. All of that is on a very low level, though. My question now is, what language should I start seriously practicing? Java: I did my first GUIs with this language. I'm familiar with Eclipse but I need a project to work on (which I don't have) to really keep me pushing. Besides that, I don't think it would help me if I have to do C in a year. C: As with Java, I can't think of a personal project to keep me working and keep me interested in programming. If I get assigned to Java in a year, this wouldn't give me any advantages either, would it? (No objects, etc.) Objective-C: I recently came up with this idea. I have a Mac; I'm not really familiar with Xcode but I have one or two personal projects I'd like to work on. Further, I would be working with objects (as in Java) and C language constructs which would both be great for this practical course in a year. What do you think I should begin with? Should I just stick to Java and hope for the best, force myself through C or start (nearly) completely from the beginning with Objective C? Maybe you folks could give me some good advice that would stop me from switching from one language to the next?

  • Draw Cards and Eliminate Cards Problem

    - by Jen
    I am having a problem in this question. I want a system inside a game wherein the player draws 2 cards randomly, and the enemy draws 2 cards randomly. Then, what the program does is to print out to the console the cards the player draw and the enemy's. The cards should not conflict and must not be the same. Then lastly, the program prints out the card that was not drawn by both the player and the enemy. Here's how I did it but it was lengthy and full of errors: import java.util.Random; public class Draw { public static Random random = new Random(); public static String cards[] = {"Hall", "Kitchen", "Billiard", "Study", "Pool"}; public static int playercounter; public static int enemycounter; public static String playercardA = null; public static String playercardB = null; public static String enemycardA = null; public static String enemycardB = null; public String lastcard = null; public static void playercardAdraw() { playercounter = random.nextInt(5); playercardA = cards[playercounter]; } public static void playercardBdraw() { playercounter=random.nextInt(5); playercardB= cards[playercounter]; if (playercardB==playercardA || playercardB == enemycardA || playercardB == enemycardB) { return; } } public static void enemycardAdraw () { enemycounter = random.nextInt(5); enemycardA=cards[enemycounter]; if (enemycardA == playercardA || enemycardA == playercardB) { return; } } public static void enemycardBdraw () { enemycounter = random.nextInt(5); enemycardB=cards[enemycounter]; if (enemycardB == playercardA || enemycardB == playercardB || enemycardB == enemycardA) { return; } } public static void main (String args []) { System.out.println("Starting to draw..."); System.out.println("Player's Turn: "); playercardAdraw(); System.out.println("Player's first card: " + playercardA); playercardBdraw(); System.out.println("Player's second card: " + playercardB); System.out.println("Enemy's Turn: "); enemycardAdraw(); System.out.println("Enemy's first card: " + enemycardA); enemycardBdraw(); System.out.println("Enemy's Second card: " + enemycardB); } }

  • Ubuntu doesn't "see" external USB Hard Disk

    - by Mina Michael
    It's NTFS. It's USB2. I'm using Ubuntu 13.04. It works perfectly fine on Windows (which excludes cable and hardware problems). I have two Ubuntu computers and it's not detected on either. It's about 500 GB. Edits: Following the first link, I input sudo lsusb in a terminal; before and after connecting the HDD. The difference was Bus 001 Device 012: ID 14cd:6116 Super Top M6116 SATA Bridge. There it is! ("sata bridge" used to appear in a windows notification when I plugged in the HDD in!). ...This means that Ubuntu detects it but is it not mounting it? I tried this: sudo mount /dev/sdb1 /mnt But gives this: mount: special device /dev/sdb1 does not exist I also tried: sudo mount /dev/sdc1 /mnt but it stays with no output forever. I left it in background for about 30 min.s. sudo fdisk -l gives out this: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xa42d04a3 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility /dev/sda2 * 80325 102481919 51200797+ 7 HPFS/NTFS/exFAT /dev/sda3 263874558 312580095 24352769 5 Extended /dev/sda4 102481920 263872511 80695296 7 HPFS/NTFS/exFAT /dev/sda5 263874560 310505471 23315456 83 Linux /dev/sda6 310507520 312580095 1036288 82 Linux swap / Solaris Partition table entries are not in disk order Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5822aaea Device Boot Start End Blocks Id System /dev/sdc1 2048 976769023 488383488 7 HPFS/NTFS/exFAT The part below "Partition table entries are not in disk order" takes about 5 minutes to appear.

    I am creating my first ever major plugin for Wordpress and I intend to share it to the community. It integrates paypal's subscription button which is very useful for people who wishe to build a membership site using Wordpress. Question: Is IPN reliable enough that there's no need to control the subscription thru cron myself? I have not tested my plugin for a span of a month or so though because doing so would eat a lot of my time.

  • Rhythmbox is not launching

    - by Somogyi László
    I'm using Rhythmbox 2.99 in Ubuntu 13.10, and when I first launch the application it searches for music and works like a charm, but if I try to launch it later again nothing happens. When I run it in terminal I get this: $ rhythmbox (rhythmbox:8860): GLib-GObject-CRITICAL **: Custom constructor for class SoupServer returned NULL (which is invalid). Unable to remove object from construction_objects list, so memory was probably just leaked. Please use GInitable instead. Segmentation fault Any ideas how to make it work again?

  • Can I use Ubuntu to write a Windows 7 ISO to USB?

    - by Salim Fadhley
    I need to create a Windows installation USB drive from an ISO file. I used UNetbootin which seems to be the only tool that can write non-Linux images. The USB disk boots (sort of), but it gets stuck at the very first stage. A UNetbootin splash screen appears that keeps counting down from 10 to 0, and then restarts. The screen looks like this: Is there a way to make Windows boot from a USB image created on Linux?

  • Determining cause of random latency/loading issues

    - by Sherwin Flight
    I'm not sure exactly what details to post in regards to my issue, because I'm not sure what is relevant. Prior to the end of September my websites all loaded quickly, in almost all cases. Loading time wasn't usually more than a few seconds. However, since the end of September I noticed a big increase in page loading times. In some cases pages were taking 30 seconds or more to load. I do have a remote monitoring service monitoring some of the sites as well, and the image below shows the response times over the past month. The response times shown at the beginning of this graph were what the usual response times were prior to this issue occurring. You can see that there has been a significant increase in response times from the beginning to the end of this graph. The thing is, the problem is not happening 100% of the time. If I click through the site, or even just keep refreshing the page, about 25% of the time the pages load quickly, the remaining 75% of the time they load slowly. Sometimes the pages take so long to load that they time out, and don't load at all. I have contacted my hosting provider, and they said things at their end was fine. I don't believe the problem is my home internet provider, because all other websites load without a problem. The server is located in Texas, USA. This also raises another interesting point. My remote monitor checks my site from two locations, California, USA, and London, England. As you can see in the chart below the response time is actually shorter when checked from London, which doesn't seem to make sense, since the server is physically closer to the California monitoring location. I would have expected the London monitoring location to have higher response times since they are physically farther away. I should also point out that in some traceroute test I've done it seem like the first connection to the server seems to take the longest, then after that the rest of the page loads quickly. Below is a little chart showing the times for the first connection to the server. So, what could be causing this problem, and what steps can I take to resolve it or at least narrow down the problem? Sending the request to the server was very quick, and receiving the reply back seems pretty quick, but the WAIT time is really long. So it connects, sends the request, but then waits close to 30 seconds before it starts receiving data back. I am also aware that there are things I can do to speed up page loading times, like reducing the number of css/js files used on a page, compressing images, etc. This is not really what the source of the problem is though, because nothing has really changed on the site since before the problem started, and other sites on the same server are loading slowly as well. Any help or advice is much appreciated.

  • Paranoid management, contractor checking work [closed]

    - by user833345
    Just wanted to get some opinions and experiences on an issue I'm having at work. First, a little background. I've been working at a company for some time (past any probation periods) and rewriting a horrendous system. No tests, incomplete and broken functionality everywhere, enough copypasta to feed a small village, redundant code, more unused SQL tables than used ones and terrible performance. I've never seen such bad code, pretty much all of it is worthy of being posted on TheDailyWTF. The company has been operating for a number of years and have had a string of bad developers working on this system. I made a call on rewriting instead of refactoring since I judged it to be less work overall and decided that the result will address the requirements more appropriately, since the central requirement is to have a future-proof system for the next decade with plenty of room to scale up. Refactoring would have entailed untangling a huge ball of yarn and at the same time integrating it with a proper foundation or building a foundation from scratch. I've introduced the latest spiffy framework, unit & functional testing, CI, a bug tracker and agile workflow to the environment. I've fixed most of the performance issues of the old system (there were no indexes on any of the tables, for example). I've created an automated deployment process for the old system. The CTO has been maintaining the old system while I have been building the new one and he has been advising management that everything is being done as per best practices. However, management is hiring a contractor to come in and verify my work. In my experience, this is unprecedented. I can understand their reasoning to an extent, since they've had bad luck in the past, but can't help but feel somewhat offended at the fact that they distrust two senior developers who have been working with them for some time enough that a third party is being brought in. And it's not just me who is under watch - people's emails are constantly checked, someone had a remote desktop application installed on their computer of which I was asked to check the usage logs to try to determine if they were stealing sensitive data and there are CCTV cameras in one of the rooms. It's the first time I've decided to disable my Skype history at work. Am I right to feel indignant here? Has anyone else ever encountered such a situation? If so, how did it work out in the end? Was it worth sticking around? Should I just find another job?

  • It's possible to fulfill the social necessity of a human being through a social game in 3D like IMVU?

    - by Totty
    (I'm not advertising nor promoting this game, as it's just an example of my experience and I would like to have your opinion about the matter if possible) I've been started researching "things" about games and I've decided to begin to play IMVU as a friend of mine said it's cool. At first it seemed just another 3d social game, not so cool.. But I've "tried to like" and after 1 day I can say I'm addicted to it! Yes; I will explain better: About the game: You can go in chat-rooms, move to positions. Some positions are like sitting in a sofa, floor, dancing alone or with a partner, kissing and more in this way. In the free version of the game there is no nudity. You can even listen to music, view youtube... The 3d graphics are quite low end, so it's not as real as the paid PC games of today. About my experience: At first I was going with my friend in chat-rooms, they seemed very nice. There were people talking about general stuff, quite like in a real life. Well, I begin to know some girls (yes, virtual girls commanded by a real girl, I hope!). Things happened: Some girls are just crazy, not like in real life, they make out in before even talking; Other girls you can speak a little bit, then they add you to their friend-list. Sometimes they invite to their virtual places. Some girls have really IMVU boyfriends only (but not in reality) and most of them don't even make up in the game, so it's really a level of commitment involved here! But from what my friend told they last for him, at least, about 3 days... Some others have real and IMVU boyfriends that are the same. Until now I haven't find a girl with different boyfriend in the IMVU and reality. Nor multiple boyfriends. There are rooms where the same people find each selves every day and speak about general stuff, relationships and so on... They are nice with you, they "feel" you and show careness. This is what amazes me, they treat you like a real human being and as being their friend in the real world. (of course it's not always like this) There are jealous girls too and competitiveness between females lol, I know you loled! This is kind of social. So today I closed my door in my room and I've played it all day long and guess what, I didn't feel a need to stay with a real person at all. Normally, If I would stay a full day alone I would get quite crazy... So the question is: It's just me that seemed to be able to fulfill my social needs or there is something more? thanks for your precious time for reading my full question,

  • PASS Summit for SQL Starters

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

  • Understanding Long Tail Keywords For SEO

    Long tail keywords are typically two or more words (a phrase) that you type into a search engine like Google when you are searching for a product, service, the answer to a question or any kind of research you might find necessary. And if you're not at the top of the search engines (preferably in one of the first 3 positions), your chances of making money online decrease substantially.
