  • How to clean up my code

    - by simion
    Being new to this i realy am trying to learn how to keep code as simple as possible, whilst doing the job its supposed to. The question i have done is from project eulur, it says Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... Find the sum of all the even-valued terms in the sequence which do not exceed four million. Here is my code below, i was wondering what the best way of simplifying this would be, for a start removing all of the .get(list.length()-1 )..... stuff would be a good start if possible but i dont really no how to? Thanks public long fibb() { ArrayList<Integer> list = new ArrayList<Integer>(); list.add(1); list.add(2); while((list.get(list.size() - 1) + (list.get(list.size() - 2)) < 4000000)){ list.add((list.get(list.size()-1)) + (list.get(list.size() - 2))); } long value = 0; for(int i = 0; i < list.size(); i++){ if(list.get(i) % 2 == 0){ value += list.get(i); } } return value; }

  • Ordering the results of a Hibernate Criteria query by using information of the child entities of the

    - by pkainulainen
    I have got two entities Person and Book. Only one instance of a specific book is stored to the system (When a book is added, application checks if that book is already found before adding a new row to the database). Relevant source code of the entities is can be found below: @Entity @Table(name="persons") @SequenceGenerator(name="id_sequence", sequenceName="hibernate_sequence") public class Person extends BaseModel { @Id @Column(name = "id") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "id_sequence") private Long id = null; @ManyToMany(targetEntity=Book.class) @JoinTable(name="persons_books", joinColumns = @JoinColumn( name="person_id"), inverseJoinColumns = @JoinColumn( name="book_id")) private List<Book> ownedBooks = new ArrayList<Book>(); } @Entity @Table(name="books") @SequenceGenerator(name="id_sequence", sequenceName="hibernate_sequence") public class Book extends BaseModel { @Id @Column(name = "id") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "id_sequence") private Long id = null; @Column(name="name") private String name = null; } My problem is that I want to find persons, which are owning some of the books owned by a specific persons. The returned list of persons should be ordered by using following logic: The person owning most of the same books should be at the first of the list, second person of the the list does not own as many books as the first person, but more than the third person. The code of the method performing this query is added below: @Override public List<Person> searchPersonsWithSimilarBooks(Long[] bookIds) { Criteria similarPersonCriteria = this.getSession().createCriteria(Person.class); similarPersonCriteria.add(Restrictions.in("ownedBooks.id", bookIds)); //How to set the ordering? similarPersonCriteria.addOrder(null); return similarPersonCriteria.list(); } My question is that can this be done by using Hibernate? And if so, how it can be done? I know I could implement a Comparator, but I would prefer using Hibernate to solve this problem.

  • How to make restrictions on XML Schema Complex type?

    - by chobo2
    Hi I am reading the tutorials on w3cschools ( http://www.w3schools.com/schema/schema_complex.asp ) but they don't seem to mention how you could add restrictions on complex types. Like for instance I have this schema. <xs:element name="employee"> <xs:complexType> <xs:sequence> <xs:element name="firstname" type="xs:string"/> <xs:element name="lastname" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> now I want to make sure the firstname is no more then 10 characters long. How do I do this? I tried to put in the simple type for the firstname but it says I can't do that since I am using a complex type. So how do I put restrictions like that on the file so the people who I give the schema to don't try to make the firstname 100 characters.

  • How do I specify the foreign key on a many-to-one relationship when is not a property on the object

    - by jjujuma
    I'm trying to map a many-to-one relationship from MarketMenuBranch to Market. My classes look like: public class Market implements Serializable { private int id; private String name; private List<MarketMenuBranch> marketMenuBranches; // accessors / mutators etc... public class MarketMenuBranch implements Serializable { private MarketMenuBranchId id; private String name; // accessors / mutators etc... public class MarketMenuBranchId implements Serializable { private int marketId; private int sequence; // accessors / mutators etc... But I don't know what I can put for the property name (where I have ???? below). I really want to put id.marketId but that seems to be wrong. <class name="MarketMenuBranch" table="MARKET_MENU_BRANCH"> <composite-id name="id" class="MarketMenuBranchId"> <key-property name="marketId"/> <key-property name="sequence"/> </composite-id> <property name="name"/> <many-to-one name="????????"/> </class> How can I do this?

  • Compression Program in C

    - by Delandilon
    I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

  • Comparing C++ input with array values

    - by Security_Gate
    Hey everyone, Over the last couple months I've still been slowly but surely trudging through C++, and I've run into a snag that I've been meaning to figure out. I've tried asking/reading/searching, but I could never find an appropriate answer. Maybe it is simply because the question is sort of difficult to ask. What I'm trying to do is at the end of my program, have the end sequence compare the input value with values within an Array. Do I have to loop a comparison sequence? Is there an easier way around this? #include <iostream> #include <string> using namespace std; int main () { string YesAnswers[5] = {"Y", "YES", "yes" "y"}; string Name; string YN; do { cout << "Enter your name: "; getline(cin, Name); cout << "Your name is "<< Name; cout <<"\nIs this correct? Y\N: "; cin >> YN; } while(YN == YesAnswers); system("Pause"); return 0; }

  • Wireless access point -> Powerline -> Router -> Internet, should this work?

    - by Anthony
    My network at home used to be a laptop and desktop connected wirelessly to a single Wireless ADSL router, a Cisco 877W. Wireless reception around the house with this setup was quite unreliable, so I've gone about looking to improve it. I purchased some Belkin Gigabit powerline adapters and I've got these working fine. I can hook a computer up to one of the powerline adapters, and with the other one plugged into the ADSL router the computer has internet access. Additionally I can hook a Netgear DG834G Wireless ADSL router into it with the adsl not plugged in, and after turning off DHCP can RJ45 a computer up to the network. Everything works fine. However, if I setup a wireless network on the Netgear then any computer that connects wirelessly to it cannot access the internet. It gets an IP address very slowly via DHCP which is a good one, but it cannot access the internet. It can however communicate with the RJ45'd computer also connected to the Netgear. I wondered whether this could be a problem with the Netgear so I've borrowed a Cisco Aironet 1200 and got this working fine when it's attached directly to the primary ADSL router. I can connect to it wireless and get onto the internet. However, if I then plug it into the Netgear I can communicate with other devices attached to the Netgear, but can't get any further than the Netgear. All the while though the other devices RJ45'd to the Netgear are communicating with the internet just fine. I'm starting to suspect it's one of two things causing the problem: 1) For some reason the belkin powerline adapters don't like carrying wireless-originating signals. Could this be possible? 2) The primary Cisco ADSL router doesn't want to communicate with other devices on my network more than one hop away from it. I'm making an assumption here that within the Netgear box the wireless and wired sides are handled differently. Could this be true? Has anyone successfully setup something similar to what I'm trying, with a wireless device on the otherside of a pair of powerline connectors? Update 06/07/2010 - Response to irrational John 28 June Thanks for the answer John - and for clearing up some of my questions. The model number of the belkin powerline adapters are F5D4076. Security was apparently enabled by default on them, and I didn't change them from their default setting. The network diagram in your answer shows exactly what I'm trying to setup: I've followed that guide and I'm still not able to get things working properly. The thing that perplexes me is that wired network traffic works just fine - it's only the wireless traffic that doesn't. This is with the same laptop, and the same DHCP or static IPs. "1. What IP addresses did you assign to each router? What subnet masks are you using?" - subnet is 255.255.255.0, the router connected to the adsl is 192.168.153.1 and that has the DHCP server. The access point on the other side of the powerline adapters I've tried both a static IP of 192.168.153.110, same subnet, and a DHCP-assigned IP. The other devices are DHCP, although I also tried manually entering IP settings. "2. Have you correctly enabled DHCP on only one of the routers and disabled it on all the others?" Yes I have - only the internet-connected router has DHCP enabled. The IP range for the DHCP is from 192.168.153.11 - 192.168.153.200. The strange thing is that wired connections work fine on the LAN, plugged into any router, work fine - it's only the wireless connections that aren't working when they're plugged into the non-primary AP. "Since the routers you are using appear to integrate an ADSL modem I'm assuming there is no WAN port on them." There's no NAT within the LAN, and all wired connections are connected to LAN ports. It's something wrong with the wireless - wired works fine throughout the whole LAN. Update 06/07/2010 - Response to irrational John 29 June The diagram you've drawn in your answer shows pretty much exactly what I'm trying to do. I've spent another evening trying different things and made some progress but I'm still scratching my head. I've borrowed a Netgear access point and been trying with this, and the strange thing is that my PC is working now - this is a Windows 7 PC connected to the access point in the position of where the DG834G is in the diagram. Meanwhile, however, I have an old Powerbook G4 12" I use for music, and while that has a DHCP-assigned IP address, it's not getting any network throughput to either LAN or internet addresses. To make matters more strange, my phone appears to be intermittently working when it's on the wifi. The access point is a Netgear WPN802v1, DHCP, NAT both switched off, running firmware 2.0.9.0. Last night I set it up with exactly the same settings, and similar to tonight I could get a couple of devices to work, and a couple not to. By the morning, however, everything had stopped working - nothing could get a DHCP IP address. I rebooted the 877W earlier this evening and I'm wondering whether this is why a few things are working now. "Could it be possible that the issue could be with the 877W?" I didn't configure this - is it possible that the DHCP server only likes assigning devices that are immediately attached to it? Or similar, could a firewall be stopping too many addresses that are coming through one device? (ie. the Access Point) This could explain why devices are working at the start but then not by the end. In reply to your questions, "1. I looked at the Netgear DG834G support page. There are five versions of this router. Which version do you have? Netgear usually lists this on the label on the bottom of the router. What version of the firmware does it have?" It's a DG834Gv3, and the firmware is the last on the netgear site version 4.01.40. "3. Not knowing which version you have, I glanced at the reference manual for the DG834G v3. In the section for Wireless Settings under the subsection Wireless Access Point there is a check box for a Wireless Isolation setting. If you have this setting it should be off/unchecked. If it is checked then any device connected via wireless would not be able to talk to any other device on the LAN. This sounds like your problem so maybe this is the cause?" I've checked this and it's switched off. I've made a change to the IP of the access point to something outside the DHCP range - it's now 192.158.153.5, with DHCP starting at 11 and going up to 254. Thanks for the tip about this - I only have a few devices so wouldn't anticipate the DHCP server assigning up to 110, but better safe than sorry. Finally one more thing I thought I should add, is with the Powerbook G4 that's not working - it's getting a DHCP IP address and it can communicate with the WPN802 as I can visit the administration page. Anything further than this, however, it can't reach; I can't administrate the 192.168.153.1 (877W router). Strangely, however, when I open Finder on the same powerbook it's detecting my NAS which is attached directly via wire to the 877W. If I try to browse it, it says connection failed. RE: "Perhaps the problem with your Powerbook is with DNS?.." The IP settings on the powerbook are identical to that of the PC with the exception of the IP address; the PC is 192.168.153.17 and the powerbook is 192.168.153.12. Subnets are the same, 255.255.255.0 and default gateway is the same, .1, and the DNS servers are the same. I administrate the 877W by going to 192.168.153.1 in the browser. This is what isn't working from the Powerbook, despite the PC working fine when I do the same. Meanwhile, however, I can administrate the AP on 192.168.153.5 from both PC and Powerbook Update 06/07/2010 - FINAL RESOLUTION of sorts: First off, sorry for the length of this question. I need start to practice a more concise writing style, so I'm going to try to keep this bit brief. After much fiddling, and with the hugely-appreciated help of irrational John, I have come to the conclusion that it's something wrong with the powerbook. I believe that this was perhaps the reason I doubted things worked at the very beginning. I now have the original DG834Gv3 running both wirelessly and wired, and both wired devices and wireless devices get internet connectivity. The only anomaly is the powerbook which I've had to keep wired, as no matter what I do it refuses to work wirelessly. I still have suspicions that the 877W isn't quite right; I'm fairly sure that if I RJ45 the powerline adapter into a different LAN port on it then everything will break. I've just about run out of patience to test this further, and I think I need to go into the 877W's config to match the 877w's lan port's settings. I'm accepting irrational John's answer as he's been enormously helpful, way above the call of duty, and for this line he wrote: Beats the heck out of me. which in the midst of great frustration made me chuckle, and for a sentence in one of his comments to the same answer: If it is specific to the Powerbook I would put that issue aside until after you feel you have the rest of your LAN and the additional WAP all working together correctlyt It was this second sentence that made me put the powerbook aside and concentrate on the other devices that ultimately led me to getting things working.

  • Error 0x800f0922 installing .NET 3.5 on Windows 8

    - by Benjamin Nolan
    I'm trying to install .NET 3.5 on my Windows 8 box and it keeps throwing Error 0x800f0922 at me. From what I've read on answers.microsoft.com and StackOverflow I gather the easiest way to fix this is to perform a system refresh, however this will remove all software I've installed from discs. I've just moved house, so I'd rather not do that as I don't know where all the installation media actually are for a lot of my software, so if possible I'd prefer to track down where the problem is actually occurring. (Also, I have a LOT of software installed. It'd take me a long time to reinstall it all, and I unfortunately haven't got that time.) The on-demand error screen sends me to KB2734782 (can't link it as I'm <10 rep), which doesn't help much. When I run this DISM line from the StackOverflow post: Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess I get the following output on the terminal: Microsoft Windows [Version 6.2.9200] (c) 2012 Microsoft Corporation.

  • Exception seem in an eclipse GMF application when file not present in workspace

    - by rush00121
    I am developing a GMF application . In this situation , I start my workspace and load a file in the workspace . Then I close the workspace and then delete the file from the workspace . After that, I try to restart my application and restore the workspace . Of course , now since the file does not exist , there are going to be exceptions . I tried a lot to handle these exceptions but if I try to get rid of one exception , then another pops up .

  • UML assignment question

    - by waitinforatrain
    Hi guys, Sorry, I know this is a very lame question to ask and not of any use to anyone else. I have an assignment in UML due tomorrow and I don't even know the basics (all-nighter ahead!). I'm not looking for a walkthrough, I simply want your opinion on something. The assignment is as follows (you only need to skim over it!): ============= Gourmet Surprise (GS) is a small catering firm with five employees. During a typical weekend, GS caters fifteen events with twenty to fifty people each. The business has grown rapidly over the past year and the owner wants to install a new computer system for managing the ordering and buying process. GS has a set of ten standard menus. When potential customers call, the receptionist describes the menus to them. If the customer decides to book an event (dinner, lunch, picnic, finger food etc.), the receptionist records the customer information (e.g., name, address, phone number, etc.) and the information about the event (e.g., place, date, time, which one of the standard menus, total price) on a contract. The customer is then faxed a copy of the contract and must sign and return it along with a deposit (often a credit card or by check) before the event is officially booked. The remaining money is collected when the catering is delivered. Sometimes, the customer wants something special (e.g., birthday cake). In this case, the receptionist takes the information and gives it to the owner who determines the cost; the receptionist then calls the customer back with the price information. Sometimes the customer accepts the price, other times, the customer requests some changes that have to go back to the owner for a new cost estimate. Each week, the owner looks through the events scheduled for that weekend and orders the supplies (e.g., plates) and food (e.g., bread, chicken) needed to make them. The owner would like to use the system for marketing as well. It should be able to track how customers learned about GS, and identify repeat customers, so that GS can mail special offers to them. The owner also wants to track the events on which GS sent a contract, but the customer never signed the contract and actually booked a GS. Exercise: Create an activity diagram and a use case model (complete with a set of detail use case descriptions) for the above system. Produce an initial domain model (class diagram) based on these descriptions. Elaborate the use cases into sequence diagrams, and include any state diagrams necessary. Finally use the information from these dynamic models to expand the domain model into a full application model. ============= In your opinion, do you think this question is asking me to come up with a package for an online ordering system to replace the system described above, or to create UML diagrams that facilitate the existing telephone-based system?

  • MDT 2012 Image Capture

    - by floyd
    I am using MDT 2012 Update 1. Attempting to Deploy 2012 DC to a VM, run windows updates, and then sysprep/capture that image. This is the same task sequence process I have used for Windows 7 / 2008 R2 and it works fine. However, for 2012 DC it deploys the image, starts running/installing updates and then on reboot it goes to a "Choose an option" screen if I choose "Exit and continue to Windows Server 2012" it reboots and goes back to same screen. Any ideas?

  • Getting template metaprogramming compile-time constants at runtime

    - by GMan - Save the Unicorns
    Background Consider the following: template <unsigned N> struct Fibonacci { enum { value = Fibonacci<N-1>::value + Fibonacci<N-2>::value }; }; template <> struct Fibonacci<1> { enum { value = 1 }; }; template <> struct Fibonacci<0> { enum { value = 0 }; }; This is a common example and we can get the value of a Fibonacci number as a compile-time constant: int main(void) { std::cout << "Fibonacci(15) = "; std::cout << Fibonacci<15>::value; std::cout << std::endl; } But you obviously cannot get the value at runtime: int main(void) { std::srand(static_cast<unsigned>(std::time(0))); // ensure the table exists up to a certain size // (even though the rest of the code won't work) static const unsigned fibbMax = 20; Fibonacci<fibbMax>::value; // get index into sequence unsigned fibb = std::rand() % fibbMax; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << Fibonacci<fibb>::value; std::cout << std::endl; } Because fibb is not a compile-time constant. Question So my question is: What is the best way to peek into this table at run-time? The most obvious solution (and "solution" should be taken lightly), is to have a large switch statement: unsigned fibonacci(unsigned index) { switch (index) { case 0: return Fibonacci<0>::value; case 1: return Fibonacci<1>::value; case 2: return Fibonacci<2>::value; . . . case 20: return Fibonacci<20>::value; default: return fibonacci(index - 1) + fibonacci(index - 2); } } int main(void) { std::srand(static_cast<unsigned>(std::time(0))); static const unsigned fibbMax = 20; // get index into sequence unsigned fibb = std::rand() % fibbMax; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << fibonacci(fibb); std::cout << std::endl; } But now the size of the table is very hard coded and it wouldn't be easy to expand it to say, 40. The only one I came up with that has a similiar method of query is this: template <int TableSize = 40> class FibonacciTable { public: enum { max = TableSize }; static unsigned get(unsigned index) { if (index == TableSize) { return Fibonacci<TableSize>::value; } else { // too far, pass downwards return FibonacciTable<TableSize - 1>::get(index); } } }; template <> class FibonacciTable<0> { public: enum { max = 0 }; static unsigned get(unsigned) { // doesn't matter, no where else to go. // must be 0, or the original value was // not in table return 0; } }; int main(void) { std::srand(static_cast<unsigned>(std::time(0))); // get index into sequence unsigned fibb = std::rand() % FibonacciTable<>::max; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << FibonacciTable<>::get(fibb); std::cout << std::endl; } Which seems to work great. The only two problems I see are: Potentially large call stack, since calculating Fibonacci<2 requires we go through TableMax all the way to 2, and: If the value is outside of the table, it returns zero as opposed to calculating it. So is there something I am missing? It seems there should be a better way to pick out these values at runtime. A template metaprogramming version of a switch statement perhaps, that generates a switch statement up to a certain number? Thanks in advance.

  • MindMap in silverlight

    - by JAllen
    I need to put together a team to build a silverlight based application that will read an xml file and generate a Mind Map diagram based on that file. I am new to silverlight and I need to find out what skills do I need and how difficult is it to do something like this. I expect the typical Mind Map features available in a commercial Mind Map software, like the ability to open and collapse nodes and to move the nodes around the screen.

  • Displaying FontFamily in Combobox

    - by Torsten
    Hi. My goal is to manipulate the text-styles of my application via DependencyProperties. I got a diagram in which the texts are to be manipulated in size, fontfamily, color, etc. So I'd like to use an interface similar to a rich text editor like Word. I'm using this code in my TextStyleVM http://shevaspace.blogspot.com/2006/12/i-have-some-fun-with-formattedtext_14.html So I have a FontFamilyProperty and a Getter and Setter for it: public static DependencyProperty FontFamilyProperty = DependencyProperty.Register( "FontFamily", typeof(FontFamily), typeof(OutlinedText), new FrameworkPropertyMetadata( SystemFonts.MessageFontFamily, FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.AffectsMeasure), new ValidateValueCallback(IsValidFontFamily)); public FontFamily FontFamily { get { return (FontFamily)base.GetValue(FontFamilyProperty); } set { base.SetValue(FontFamilyProperty, value); } } Then there is a ToStyle method, which sets the style for the labels of the diagram, which are to be manipulated: Style style = new Style(); Binding fontFamilyBinding = new Binding("FontFamily"); fontFamilyBinding.Source = this; Setter fontFamilySetter = new Setter(); fontFamilySetter.Property = TextBlock.FontFamilyProperty; fontFamilySetter.Value = fontFamilyBinding; style.Setters.Add(fontFamilySetter); return style; Now this works for a TextBox. The textbox displays the current FontFamily, and if I enter a new, valid FontFamily like Arial into the textbox the FontFamily of the labels are changed. However, what I'd like to have is a combobox, which displays the SystemFonts and where I can choose one FontFamily for my labels. However, the binding doesn't seem to work. Neither the system fonts nor the current fonts of the labels are displayed. The combobox is just empty. This is my xaml: <r:RibbonLabel Content="FontFamily" /> <!--these do not work--> <r:RibbonComboBox SelectedItem="{Binding FontFamily}"/> <r:RibbonComboBox ItemsSource="{Binding FontFamily}"/> <!--this works--> <r:RibbonTextBox Text="{Binding FontFamily}"/> Now, I assume I have to set a different Setter for a ComboBox in the ToStyle Method. But I have no clue, which one. Maybe someting like this: fontFamilySetter.Property = ComboBox.ItemSource; However, if I set that Property, the TextBox still works. So is this the wrong place to start at? I'd also be grateful if someone could hint me to some documentation about using these Style-, Setter-, Binding-key-words, which are used in the ToStyle method, since this is somebody elses code I'm working with.

  • How to create a Turing machine that takes a single digit decimal number from 0 - 9 and output the cu

    - by Julian
    I'm working on a project for a Turning machine but having problems conceptualizing the steps. f(x) = x^3, where x is a single digit between 0 - 9 inclusive. Based on my understanding I am to convert the number to binary but how do I find the cube of a number in binary. Also, how do I write the cube on the tape. So far I'm thinking I should create a state diagram that accepts the binary versions of 0-9 but what next?

  • Ctrl-Alt-Delete doesn't unlock PC when VMPlayer is on

    - by NealWalters
    My desktop XP OS gets locked after I leave for x minutes. I have VMPlayer occupying full screen mode. I think the keyboard is redirected to VMWare. I press Ctrl + Alt + Delete and outer-machine XP is not unlocking. I think maybe keyboard is going to VMWare, because this seems to only happen when I have VMWare running. How do I unlock XP? Is there some magic key sequence?

  • IIS Express only utilizes 13% of i7 Quad Core

    - by John Nevermore
    Since one of my scripts got incredibly complex, i was benchmarking the performance of moving some javascript processing logic to the server side in my ASP.NET MVC 4 application. According to taskmgr.exe, IIS Express only utilizes 13% of my i7. I decided to throw in 3 parallel tasks calculating the fibonacci sequence up to 50 and the IIS express still wouldn't utilize more than 13% of my cpu. Is there anything i can do, so that the application utilizes the full cpu, as it would in a real server ?

  • Restart mysql keeping the data

    - by sitonico
    I'm quite new using mysql, so let me know if I'm missing something. I took some holidays, and when I got back to work and I tried to log in phpmyadmin I got a ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2). I never had this problem, so I was browsing to look for a solution. I tried some things, and I'm afraid I touched too much. I couldn't solve the problem, and the I realized that I had some actualizations to be done, and I thought that they may be helpful for mysql. Then I also realized that when I was doing this actualizations first day, they stopped because I had a lack of space, so I restarted then. Then,when the system was configuring mysql, it didn't advance. I waited for a long time and then I just stopped it and restarted the computer. After it, I just tried to uninstall mysql with sudo apt-get remove mysql-server-5.1, and install it again, but it didn't work. Now I have 2 questions: What do you think it is happening? Should I remove mysql completely? What should I do? I'm afraid of losing my databases, is there anyway to recover the data? Thank you very much in advance. -----------EDIT------- These are the messages: alfonso@alfonso-laptop:/$ tail -F /var/log/syslog | grep Feb 15 15:08:01 alfonso-laptop init: mysql post-start process (15192) terminated with status Feb 15 15:08:01 alfonso-laptop init: mysql main process (15263) terminated with status Feb 15 15:08:01 alfonso-laptop init: mysql main process ended, Feb 15 15:08:31 alfonso-laptop init: mysql post-start process (15264) terminated with status Feb 15 15:08:31 alfonso-laptop init: mysql main process (15358) terminated with status Feb 15 15:08:31 alfonso-laptop init: mysql main process ended, Feb 15 15:09:01 alfonso-laptop init: mysql post-start process (15359) terminated with status Feb 15 15:09:01 alfonso-laptop init: mysql main process (15447) terminated with status Feb 15 15:09:01 alfonso-laptop init: mysql main process ended, Feb 15 15:09:32 alfonso-laptop init: mysql post-start process (15448) terminated with status 1 This is the content of error.log-old 110128 13:17:20 [Note] /usr/sbin/mysqld: Normal shutdown 110128 13:17:20 [Note] Event Scheduler: Purging the queue. 0 events 110128 13:17:20 InnoDB: Starting shutdown... 110128 13:17:22 InnoDB: Shutdown completed; log sequence number 0 590872 110128 13:17:22 [Note] /usr/sbin/mysqld: Shutdown complete 110214 2:08:18 [Note] Plugin 'FEDERATED' is disabled. 110214 2:08:19 InnoDB: Started; log sequence number 0 590872 110214 2:08:19 [Note] Event Scheduler: Loaded 0 events 110214 2:08:19 [Note] /usr/sbin/mysqld: ready for connections.
