  • SQL Server 2008R2 Express: which is the users limit in a real case scenario?

    - by PressPlayOnTape
    I know that sql server express has not a user limit, and every application has a different way to load/stress the server. But let's take "a typical accounting software", where users input some record, retrieve some data and from time to time they make some custom big queries. May someone share its own experience and tell me which is the limit of users that can realistically use a sql server express instance in this scenario? I am looking for an indicative idea, like (as an example): "I had a company with an average of 40 users logged in and the application was working ok on sql server express, but when the users become 60 the application started to seem non repsonsive" (please note this sentence is pure imagination, I just wrote it as an example).

  • Index Check and Correct Character Display in a Console Hangman Game for Java

    - by Jen
    I have this problem wherein, I can not display the correct characters given by the character. Here's what I meant: String words, in; String replaced_words; Scanner s = new Scanner (System.in); System.out.println("Enter a line of words basing on an event, verse, place or a name of a person."); words = s.nextLine(); System.out.println("The words you just placed are now accepted."); //using char array method, we tried to place the words into a characters array. char [] c = words.toCharArray(); // we need to replace the replaced_words = words.replace(' ', '_').replaceAll("[^\\-]", "-"); for (int i = 0; i < replaced_words.length(); i++) { System.out.print(replaced_words.charAt(i) + " "); } System.out.println("Now, please input a character, guessing the words you just placed."); in = s.nextLine(); in that code, want that the user, when types a word (or should it be character?), any of the correct character the user inputs will be displayed, and changes the hyphen to it...(more like the hangman series of games). How can I achieve this?

  • Application toolkits like QT versus traditional game/multimedia libraries like SFML

    - by Aaron
    I currently intend to use SFML for my next game project. I'll need a substantial GUI though (RPG/strategy-type) so I'll either have to implement my own or try to find an appropriate third party library, which seem to boil down to CEGUI, libRocket, and GWEN. At the same time, I do not anticipate doing that many advanced graphical effects. My game will be 2D and primarily sprite-based with some sprite animations. I've recently discovered that QT applications can have their appearance styled so that they don't have to look like plain OS apps. Given that, I am beginning to consider QT a valid alternative to SFML. I wouldn't have to implement the GUI functionality I'd need, and I may not be taking advantage of SFML's lower-level access anyway. The only drawbacks I can think of immediately are the learning curve for QT and figuring out how to fit game logic inside such a framework after getting used to the input/update/render loop of traditional game libraries. When would an application toolkit like QT be more appropriate for a game than a traditional game or multimedia library like SFML?

  • Can I increase the link speed of the RAS Server on our MS Win2k3 box?

    - by Ducain
    We are running a Win2K3 Server box, and I'm a remote employee that connects via VPN. I've been frustrated for some time by the connection speed over the VPN (the office HQ has a decent speed and I have a biz class connection here), and decided to do some checking today. This morning, I was dialed in and looked at the networking tab of the task manager, and I see that the adapter for the RAS Server (the box has 4 Gigabit adapters) has a speed that seems far too low. The speed for the RAS Server link hovers between 300 - 600 Kbps. The local connection (and others) all say 1 Gbps. Can I set this to a higher speed? Is this information accurate? Thanks for the input.

  • Can higher-order functions in FP be interpreted as some kind of dependency injection?

    - by Giorgio
    According to this article, in object-oriented programming / design dependency injection involves a dependent consumer, a declaration of a component's dependencies, defined as interface contracts, an injector that creates instances of classes that implement a given dependency interface on request. Let us now consider a higher-order function in a functional programming language, e.g. the Haskell function filter :: (a -> Bool) -> [a] -> [a] from Data.List. This function transforms a list into another list and, in order to perform its job, it uses (consumes) an external predicate function that must be provided by its caller, e.g. the expression filter (\x -> (mod x 2) == 0) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] selects all even numbers from the input list. But isn't this construction very similar to the pattern illustrated above, where the filter function is the dependent consumer, the signature (a -> Bool) of the function argument is the interface contract, the expression that uses the higher-order is the injector that, in this particular case, injects the implementation (\x -> (mod x 2) == 0) of the contract. More in general, can one relate higher-order functions and their usage pattern in functional programming to the dependency injection pattern in object-oriented languages? Or in the inverse direction, can dependency injection be compared to using some kind of higher-order function?

  • What is the value to checking in broken unit tests?

    - by Adam W.
    While there are ways of keeping unit tests from being executed, what is the value of checking in broken unit tests? I will use a simple example. Case sensitivity. The current code is Case Sensitive. A valid input into the method is "Cat" and it would return an enum of Animal.Cat. However, the desired functionality of the method should not be case sensitive. So if the method described was passed "cat" it could possibly return something like Animal.Null instead of Animal.Cat and the unit test would fail. Though a simple code change would make this work, a more complex issue may take weeks to fix, but identifying the bug with a unit test could be a less complex task. The application currently being analyzed has 4 years of code that "works". However, recent discussions regarding unit tests has found flaws in the code. Some just need explicit implementation documentation (ex. case sensitive or not), or code that does not execute the bug based on how it is currently called. But unit tests can be created executing specific scenarios that will cause the bug to be seen and are valid inputs. What is the value of checking in unit tests that exercise the bug until someone can get around to fixing the code? Should this unit test be flagged with ignore, priority, category etc, to determine whether a build was successful based on tests executed? Eventually the unit test should be created to execute the code once someone fixes it. On one hand it shows that identified bugs have not been fixed. On the other, there could be hundreds of failed unit tests showing up in the logs and weeding through the ones that should fail vs. failures due to a code check-in would be difficult to find.

  • How do references work in R?

    - by djechlin
    I'm finding R confusing because it has such a different notion of reference than I am used to in languages like C, Java, Javascript... Ruby, Python, C++, well, pretty much any language I have ever programmed in ever. So one thing I've noticed is variable names are not irrelevant when passing them to something else. The reference can be part of the data. e.g. per this tutorial a <- factor(c("A","A","B","A","B","B","C","A","C")) results <- table(a) Leads to $a showing up as an attribute as $dimnames$a. We've also witnessed that calling a function like a <- foo(alpha=1, beta=2) can create attributes in a of names alpha and beta, or it can assign or otherwise compute on 1 and 2 to properties already existing. (Not that there's a computer science distinction here - it just doesn't really happen in something like Javascript, unless you want to emulate it by passing in the object and use key=value there.) Functions like names(...) return lvalues that will affect the input of them. And the one that most got me is this. x <- c(3, 5, 1, 10, 12, 6) y = x[x <= 5] x[y] <- 0 is different from x <- c(3, 5, 1, 10, 12, 6) x[x <= 5] <- 0 Color me confused. Is there a consistent theory for what's going on here?

  • Alternative to the tee command whitout STDOUT

    - by aef
    I'm using | sudo tee FILENAME to be able to write or append to a file for which superuser permissions are required quite often. Although I understand why it is helpful in some situation, that tee also sends its input to STDOUT again, I never ever actually used that part of tee for anything useful. In most situations, this feature only causes my screen to be filled with unwanted jitter, if I don't go the extra step and manually silence it with tee 1> /dev/null. My question: Is there is a command arround, which does exactly the same thing as tee, but does by default not output anything to STDOUT?

  • Logfiles filling with iptables logging

    - by Peter I
    OS: Debian 6 Server Version I have different logfiles which are filling up: user@server:/var/log$ ls -lahS | head total 427G -rw-r--r-- 1 root root 267G Nov 2 17:29 bandwidth -rw-r----- 1 root adm 44G Nov 2 17:29 kern.log -rw-r----- 1 root adm 27G Nov 2 17:29 debug -rw-r----- 1 root adm 23G Oct 27 06:33 kern.log.1 -rw-r----- 1 root adm 17G Nov 2 17:29 messages -rw-r----- 1 root adm 14G Oct 27 06:33 debug.1 -rw-r----- 1 root adm 12G Nov 2 17:29 syslog -rw-r----- 1 root adm 12G Nov 1 06:26 syslog.1 -rw-r----- 1 root adm 9.0G Oct 27 06:33 messages.1 So I looked up the file /etc/iptables.up.rules which had those lines in it: -A FORWARD -o eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_OUT: -A FORWARD -i eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_IN: -A OUTPUT -o eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_OUT: -A INPUT -i eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_IN: So deleting those lines will solve my problem. But how would I edit those lines without losing their functionality?

  • Standard for feeding test data to a Nagios plugin?

    - by chiborg
    I'm developing a Nagios plugin in Perl (no Nagios::Plugin, just plain Perl). The error condition I'm checking for normally comes from a command output, called inside the plugin. However, it would be very inconvenient to create the error condition, so I'm looking for a way to feed test output to the plugin to see if it works correctly. The easiest way I found at the moment would be with a command line option to optionally read input from a file instead of calling the command. if($opt_f) { open(FILE, $opt_f); @output = <FILE>; close FILE; } else { @output = `my_command`; } Are there other, better ways to do this?

  • Scripting language for filling out web form

    - by ityler22
    I have a job as an intern at a technology company, I was given the unfortunate job of performing some data entry into our web management system. The information entered into the web form is stored in a MySQL DB. Upon receiving the data I realized I would have to submit this online form about 1000 different times all consisting of about 10 different text fields / check boxes per form. (So in other words, would be completely mind numbing and be a ridiculous waste of time and resources, or so I thought...) Having used databases a good bit prior to this, my immediate reaction was to just write a short MySQL script to bulk import all of the data, especially since it was already presented to me in an excel spreadsheet ready to go. Thought it may have been some sort of a test since it seemed too obvious. I wrote the script which consisted of about 10 lines of code but was then informed I couldn't be trusted with MySQL Admin privileges to run said script. So my next thought would be to write a script to just enter the information through the web form (Which will take ten times longer but it's what I have to) Being unfamiliar with scripting of this nature (seems like I would need something similar to a bot, but the good kind) I was unsure of how to proceed to do this. Is there a preferred language to use to enter the data i have into the web form I do have access to? I'm not particularly looking for this to be done for me by any means just a nice point in the right direction as far as what scripting language to use and how to pair that with the data I have that needs to be entered. Thanks for the help/ valuable input! EDIT: Is there a way to perform this using perl without having access to place any files on the server? Would I be able to run some Javascript loops to pull the data out of .csv or just a .txt format with line delimiters and insert it into the web form?

  • Setting a wireless access point on Ubuntu server 11.10

    - by Solignis
    I am trying to setup a wifi access point with my Ubuntu server. I have managed to get my phone to connect the wireless and now it get a DHCP lease. Though it still cannot ping out or get pinged by anything on my network. I am prety sure my problem is iptables, but I not sure what would be wrong. Here is what my rules look like. (The ones pertaining to the bridge interface) # Allow traffic to / from wireless bridge interface iptables -A INPUT -i br0 -j ACCEPT iptables -A OUTPUT -o br0 -j ACCEPT I am guessing my rules are a little lean, the bridge exists on the same subnet as everything else on my network, I am using a 10.0.0.0/24 subnet. EDIT Oh yeah I should mention also, when I do a ping test, I get Destination Host Unreachable as the error.

  • Install on Acer Aspire 4752

    - by user216962
    I am at my wits end with this computer. I bought and Acer Aspire 4752 with a fully loaded version of Windows 7 on it. I prefer Ubuntu so I began to install 14.04 from USB. Got the error: [Errno 5] Input/output error This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment. So I tried a different USB stick, same error. Tried different versions of Ubuntu, got the same error. I've used startup disk creator and Unetbootin to make start USB boot devices. I can boot with the USB drive and run Ubuntu that way. I even checked the hard drive using the tools in Ubuntu. Everything was fine, except it said the hard drive was hot. I tried a different hard drive. Got same error above. I ran a test with mem86, everything was fine. No matter what I do, using the USB gives me the Errno5 error. I then switched to using DVDs. Now I keep getting an uncompression error when installing Ubuntu 14.04 or 12.04. I can't figure out for the life of me why I get nothing but errors. Can anyone help?

  • How granular should a command be in a CQ[R]S model?

    - by Aaronaught
    I'm considering a project to migrate part of our WCF-based SOA over to a service bus model (probably nServiceBus) and using some basic pub-sub to achieve Command-Query Separation. I'm not new to SOA, or even to service bus models, but I confess that until recently my concept of "separation" was limited to run-of-the-mill database mirroring and replication. Still, I'm attracted to the idea because it seems to provide all the benefits of an eventually-consistent system while sidestepping many of the obvious drawbacks (most notably the lack of proper transactional support). I've read a lot on the subject from Udi Dahan who is basically the guru on ESB architectures (at least in the Microsoft world), but one thing he says really puzzles me: As we get larger entities with more fields on them, we also get more actors working with those same entities, and the higher the likelihood that something will touch some attribute of them at any given time, increasing the number of concurrency conflicts. [...] A core element of CQRS is rethinking the design of the user interface to enable us to capture our users’ intent such that making a customer preferred is a different unit of work for the user than indicating that the customer has moved or that they’ve gotten married. Using an Excel-like UI for data changes doesn’t capture intent, as we saw above. -- Udi Dahan, Clarified CQRS From the perspective described in the quotation, it's hard to argue with that logic. But it seems to go against the grain with respect to SOAs. An SOA (and really services in general) are supposed to deal with coarse-grained messages so as to minimize network chatter - among many other benefits. I realize that network chatter is less of an issue when you've got highly-distributed systems with good message queuing and none of the baggage of RPC, but it doesn't seem wise to dismiss the issue entirely. Udi almost seems to be saying that every attribute change (i.e. field update) ought to be its own command, which is hard to imagine in the context of one user potentially updating hundreds or thousands of combined entities and attributes as it often is with a traditional web service. One batch update in SQL Server may take a fraction of a second given a good highly-parameterized query, table-valued parameter or bulk insert to a staging table; processing all of these updates one at a time is slow, slow, slow, and OLTP database hardware is the most expensive of all to scale up/out. Is there some way to reconcile these competing concerns? Am I thinking about it the wrong way? Does this problem have a well-known solution in the CQS/ESB world? If not, then how does one decide what the "right level" of granularity in a Command should be? Is there some "standard" one can use as a starting point - sort of like 3NF in databases - and only deviate when careful profiling suggests a potentially significant performance benefit? Or is this possibly one of those things that, despite several strong opinions being expressed by various experts, is really just a matter of opinion?

  • Laptop screen turns off on removing power cord

    - by YatharthROCK
    After a recent upgrade to Windows 8.1 Pro from W8, my laptop's screen turns off as soon as you remove the power cord. It turns back on with no issues when you plug the power back in. Keyboard and mouse input is processed while the screen is off. My settings tell the screen to go off after 2 minutes of inactivity on battery. I was having a battery issue from before where my laptop would should down after 5 minutes of running on battery (despite showing 60% left), but I think that's unrelated. Any other info will be provided on request. Can anyone help me figure out what's going on? How can I stop this behaviour?

  • NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

    - by Big Daddy
    Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

  • TransformXml Task locks config file identified in Source attribute

    - by alexhildyard
    As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform. You can transform app.configs, or indeed any XML file that honours the task's schema and hierarchical rules.

  • BizTalk: Using context for routing

    - by Leonid Ganeline
    [See Sample: Context routing and throttling with orchestration] Imagine the project where most of the routing happens between orchestrations. I.e. routing is mostly between the MessageBox and orchestration with direct endpoints. Imagine also the most of the messages are with the same Message type. Usually in this case messages got the special node only for the routing. For example, the field can be the “Originator” or “Recipient” or “From” or “To”. What wrong is with this approach, it creates the dependency between the message and the message processing. Message “knows” something about Originator or Recipient. So what we can do with it? How can we “colorize” the same message to route it to the different places without changing the message itself? One of the decisions is to use the message context. BizTalk uses the promoted properties for routing.  There are two kinds of the properties: the content properties and the context properties. The content property extracts its value from inside the message, it is a value of the element or attribute. [See MSDN] The context property gets its value from the message environment. It can be the port name that receive this message, it can be the message Id, created by the BizTalk. Context properties look like the headers in the SOAP message. Actually they are not the headers but behave like headers. The context properties are the good match for our case. First, we don’t have to change the message itself to set or change the routing property. The context is stored outside the message body. Second, we don’t have to create the property schema to use the context properties. [See MSDN: How to create Property schema] BizTalk has the predefined schema set for the context properties. [See MSDN: Message Context Properties] Use one of them and that's it. The main purpose of the context properties is working on behalf of the BizTalk internals. But we can read, create and change them. Just do not interfere with BizTalk internals on this way.

  • Connecting PS3 dualshock on Ubuntu 14.04 with 3.13.0-34-generic?

    - by 5th Wheel
    The last entries/queries I can find about PS3 dual shock controller are dealing with older kernel versions. It looks like there may still be a problem with using the PS3 dual shock via USB(or bluetooth) with 14.04? I'm only guessing because I get no sign of detection or input when I plug in the USB. When I run dmesg | grep sony [ 4687.762302] sony 0003:054C:0268.0003: can't set operational mode [ 4687.770639] sony: probe of 0003:054C:0268.0003 failed with error -38 So at this point, I don't know if it's worth running : sudo apt-get install xboxdrv I also found this article LINK but it's dated 01/2013. I was considering installing steam, and checking out some of the games. There are a few in particular I want to check out, but I'm afraid of purchasing them and then my controller does not work. I don't have a ps3, I just have the controller for Sixaxis/emulator/Android set up... I see mentions for QTsixa and xboxdrv, but the posts are at least a year old(older distibution/kernels) Ideally, I'd like to just plug in USB, and play. No Bluetooth.

  • Data Virtualization: Federated and Hybrid

    - by Krishnamoorthy
    Data becomes useful when it can be leveraged at the right time. Not only enterprises application stores operate on large volume, velocity and variety of data. Mobile and social computing are in the need of operating in foresaid data. Replicating and transferring large swaths of data is one challenge faced in the field of data integration. However, smaller chunks of data aggregated from a variety of sources presents and even more interesting challenge in the industry. Over the past few decades, technology trends focused on best user experience, operating systems, high performance computing, high performance web sites, analysis of warehouse data, service oriented architecture, social computing, cloud computing, and big data. Operating on the ‘dark data’ becomes mandatory in the future technology trend, although, no solution can make dark data useful data in a single day. Useful data can be quantified by the facts of contextual, personalized and on time delivery. In most cases, data from a single source may not be complete the picture. Data has to be combined and computed from various sources, where data may be captured as hybrid data, meaning the combination of structured and unstructured data. Since related data is often found across disparate sources, effectively integrating these sources determines how useful this data ultimately becomes. Technology trends in 2013 are expected to focus on big data and private cloud. Consumers are not merely interested in where data is located or how data is retrieved and computed. Consumers are interested in how quick and how the data can be leveraged. In many cases, data virtualization is the right solution, and is expected to play a foundational role for SOA, Cloud integration, and Big Data. The Oracle Data Integration portfolio includes a data virtualization product called ODSI (Oracle Data Service Integrator). Unlike other data virtualization solutions, ODSI can perform both read and write operations on federated/hybrid data (RDBMS, Webservices,  delimited file and XML). The ODSI Engine is built on XQuery, hence ODSI user can perform computations on data either using XQuery or SQL. Built in data and query caching features, which reduces latency in repetitive calls. Rightly positioning ODSI, can results in a highly scalable model, reducing spend on additional hardware infrastructure.

    I currently have a computer with a ASUS EAH5770 (ATi Radeon HD 5770) 1GB GDDR5 video card, and 4GB ram, 2.6 GHZ i5 processor. I just switched from a DVI (the blue one) to an HDMI cable. (Bigben Flat cable HDMI 1.3c) I use a Samsung SyncMaster 2032 MW, which has a HDMI input. The weird thing is, that my screen is off-the-corner of the tv (so it's too wide) (1920x1080), and windows icons and text are not displaying well, though 1080p videos in YouTube are looking brilliant, just like pictures. So i think it has something to do with Windows. I already have the ATI Catalyst Control Center with the drivers i received with my video card. I do not currently know how to fix these problems. Do i have to reinstall Windows or so? Or is it (hopefully) easier?

  • Java: How to Make a Player Class in a Tile-Based RPG

    - by A.K.
    So I've been following a JavaHub tutorial that basically uses a pixel engine similar to MiniCraft. I've attempted to make a Player Class as such, and I'm basically making a mock Pokemon game for learning's sake: package pokemon.entity; import java.awt.Rectangle; import pokemon.gfx.Screen; import pokemon.levelgen.Tile; import pokemon.entity.SpritesManage;; public class Player { int x, y; int vx, vy; public Rectangle AshRec; public Sprite AshSprite; Screen screen; Sprite[][] AshSheet; public Player() { AshSprite = SpritesManage.AshSheet[1][0]; AshRec = new Rectangle(0, 0, 16, 16); x = 0; y = 0; vx = 1; vy = 1; screen.renderSprite(0, 0, AshSprite); } public void update() { move(); checkCollision(); } private void checkCollision() { } private void move() { AshRec.x += vx; AshRec.y += vy; } public void render(Screen screen, int x, int y) { screen.renderSprite(x, y, AshSprite); } } I guess what I really want to do is have the Player centered in the screen and have the sprite drawn based on an Input Handler. I'm just stumped as to how to sync these together.
