  • when is the right time to draw

    - by stupid_idiot
    hi i just finished essential part of my own personal 2d engine in c++ and i'm kinda deciding how to complete the part where it is actually supposed to display everything on the screen, namely when do I call that function which does the job. I don't have much idea of how does the graphic card work, my biggest experience is calling bios graphic services to write some stuff on the screen. Could you give me a hint on this pls? Or maybe some keywords I should try to google?

  • Need to sync two lists with atrribute time, but times aren't equal

    - by virgula24
    I gonna try to describe my problem the best i can. I have two lists, one with audio frames and other with color frames (not relevant). Both of them have timestamps, they were captured at the same moment but at different instants. So, i have like this: index COLOR AUDIO 0 841 846 1 873 897 2 905 948 3 940 1000 the frames start at high numbers because they were captured and then trimmed to specific parts, but im shot, frame 0 is synced with only 5ms apart(timestamp in ms). On every case i have, the audio frames count is less than the color count. I need to make them have the same count. The stating frames may be coloraudio, color

  • SerialPort.Open() takes very long time to execute

    - by narancha
    I'm having trouble when I'm trying to use the SerialPort.Open() function. Sometimes it opens in 5 seconds and sometimes it takes several minutes. This is my code: public void InvokeSerialPortdetectedEvent(string s) { SerialPortDetectEvent.Invoke(this, s); // the invoked funktion is called PortHandeler_SerialPortDetectEvent() } void PortHandeler_SerialPortDetectEvent(object sender, string name) { OpenSerialPort(name); AddDongleToDeviceList(); } private void OpenSerialPort(string Name) { if (serialPort1.IsOpen) { return; } serialPort1.PortName = Name; try { serialPort1.Open(); if (serialPort1.IsOpen) { Console.Write("Open Serialport: " + Name); } } catch (Exception e) { Console.Write(e.Message); Console.Write(e.StackTrace); } }

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • Ubuntu won't boot on windows starter

    - by First timer
    I installed Ubuntu 12.04 LTS yesterday from a usb, but it only boots into Windows unless the usb is in, then it boots into the Ubuntu loader where I can choose Ubuntu vs. Windows. What's the problem? I run windows starter on a netbook with 1 gb ram and intel atom processor. I tried to install boot-repair but it won't work either. I follow the instructions for the Terminal and it seems to go right until I try launching it - then it says that it does not know the command boot-repair. I really like Ubuntu, it lets this netbook run smoothly and better than ever before but I don't think I want to boot from a usb every time.

  • Why is Apache ignoring VirtualHost directive for first name in hosts file?

    - by Peter Taylor
    Standard pre-emptive disclaimer: host names, IP addresses, and directories are anonymised. Problem We have a server with Apache 2.2 (WAMP) listening on one IP and IIS listening on another. An ASP.Net application running under IIS needs to do some simple GETs from the PHP applications running under Apache to build a unified search results page. This is a virtual server, so the internal IPs are mapped somehow to external ones. The internal DNS system doesn't resolve the publicly published names under which the applications are accessed externally, so the obvious solution was to add them to etc/hosts with the internal IP address: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com After restarting Apache, phpappone.example.com stopped working. Instead of returning pages from that app, Apache was returning pages from the default site. The other PHP apps worked fine. Relevant configuration httpd.conf, summarised, says: ServerAdmin [email protected] ServerRoot "c:/server/Apache2" ServerName www.example.com Listen 10.0.1.17:80 Listen 10.0.1.17:443 # Not obviously related config options elided # Nothing obviously astandard # If you want more details, post a comment DocumentRoot "c:/server/Apache2/htdocs" <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> # Fallback for unknown host names <Directory "c:/server/Apache2/htdocs"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> # PHP apps common config <Directory "C:/Inetpub/wwwroot/phpapps"> Options FollowSymLinks -Indexes +ExecCGI AllowOverride All Order Allow,Deny Allow from All </Directory> # Virtual hosts NameVirtualHost 10.0.1.17:80 NameVirtualHost 10.0.1.17:443 <VirtualHost _default_:80> </VirtualHost> <VirtualHost _default_:443> SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Include conf/vhosts/*.conf and the vhosts files are e.g. <VirtualHost 10.0.1.17:80> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" </VirtualHost> <VirtualHost 10.0.1.17:443> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Buggy behaviour or our misunderstanding? The documentation for name-based virtual hosts says that Now when a request arrives, the server will first check if it is using an IP address that matches the NameVirtualHost. If it is, then it will look at each <VirtualHost> section with a matching IP address and try to find one where the ServerName or ServerAlias matches the requested hostname. If it finds one, then it uses the configuration for that server. If no matching virtual host is found, then the first listed virtual host that matches the IP address will be used. Yet that isn't what we observe. It seems that if the hostname is the first hostname listed against the IP address in etc/hosts then it uses the configuration from the main server and skips the virtual host lookup. Workarounds The workaround we've put in place for the time being is to add a fake line to the hosts file: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 fakename.example.com 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com This fixes the problem, but it's not very elegant. In addition, it seems a bit brittle: reordering lines in the hosts file (or deleting the nonsense value) can break it. The other obvious workaround is to make the main server configuration match that of the troublesome virtual host, but that is equally brittle. A third option, which is just ugly, would be to change the ASP.Net code to take separate config items for the IP address and the hostname and to implement HTTP manually. Ugh. The question Is there a good solution to this problem which localises any "Do not touch this!" explanations to the Apache config files?

  • SQL SERVER – OVER clause with FIRST _VALUE and LAST_VALUE – Analytic Functions Introduced in SQL Server 2012 – ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING

    - by pinaldave
    Yesterday I had discussed two analytical functions FIRST_VALUE and LAST_VALUE. After reading the blog post I received very interesting question. “Don’t you think there is bug in your first example where FIRST_VALUE is remain same but the LAST_VALUE is changing every line. I think the LAST_VALUE should be the highest value in the windows or set of result.” I find this question very interesting because this is very commonly made mistake. No there is no bug in the code. I think what we need is a bit more explanation. Let me attempt that first. Before you do that I suggest you read yesterday’s blog post as this question is related to that blog post. Now let’s have fun following query: USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO The above query will give us the following result: As per the reader’s question the value of the LAST_VALUE function should be always 114 and not increasing as the rows are increased. Let me re-write the above code once again with bit extra T-SQL Syntax. Please pay special attention to the ROW clause which I have added in the above syntax. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Now once again check the result of the above query. The result of both the query is same because in OVER clause the default ROWS selection is always UNBOUNDED PRECEDING AND CURRENT ROW. If you want the maximum value of the windows with OVER clause you need to change the syntax to UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING for ROW clause. Now run following query and pay special attention to ROW clause again. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Here is the resultset of the above query which is what questioner was asking. So in simple word, there is no bug but there is additional syntax needed to add to get your desired answer. The same logic also applies to PARTITION BY clause when used. Here is quick example of how we can further partition the query by SalesOrderDetailID with this new functions. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Above query will give us windowed resultset on SalesOrderDetailsID as well give us FIRST and LAST value for the windowed resultset. There are lots to discuss for this two functions and we have just explored tip of the iceberg. In future post I will discover it further deep.

  • Acceptance tests done first...how can this be accomplished?

    - by Crazy Eddie
    The basic gist of most Agile methods is that a feature is not "done" until it's been developed, tested, and in many cases released. This is supposed to happen in quick turnaround chunks of time such as "Sprints" in the Scrum process. A common part of Agile is also TDD, which states that tests are done first. My team works on a GUI program that does a lot of specific drawing and such. In order to provide tests, the testing team needs to be able to work with something that at least attempts to perform the things they are trying to test. We've found no way around this problem. I can very much see where they are coming from because if I was trying to write software that targeted some basically mysterious interface I'd have a very hard time. Although we have behavior fairly well specified, the exact process of interacting with various UI elements when it comes to automation seems to be too unique to a feature to allow testers to write automated scripts to drive something that does not exist. Even if we could, a lot of things end up turning up later as having been missing from the specification. One thing we considered doing was having the testers write test "scripts" that are more like a set of steps that must be performed, as described from a use-case perspective, so that they can be "automated" by a human being. This can then be performed by the developer(s) writing the feature and/or verified by someone else. When the testers later get an opportunity they automate the "script" for regression purposes mainly. This didn't end up catching on in the team though. The testing part of the team is actually falling behind us by quite a margin. This is one reason why the apparently extra time of developing a "script" for a human being to perform just did not happen....they're under a crunch to keep up with us developers. If we waited for them, we'd get nothing done. It's not their fault really, they're a bottle neck but they're doing what they should be and working as fast as possible. The process itself seems to be set up against them. Very often we end up having to go back a month or more in what we've done to fix bugs that the testers have finally gotten to checking. It's an ugly truth that I'd like to do something about. So what do other teams do to solve this fail cascade? How can we get testers ahead of us and how can we make it so that there's actually time for them to write tests for the features we do in a sprint without making us sit and twiddle our thumbs in the meantime? As it's currently going, in order to get a feature "done", using agile definitions, would be to have developers work for 1 week, then testers work the second week, and developers hopefully being able to fix all the bugs they come up with in the last couple days. That's just not going to happen, even if I agreed it was a reasonable solution. I need better ideas...

  • How can I get my first-person character in Unity to move to a ledge with an animation?

    - by BallzOfSteel
    I'm trying to get this to happen: The character walks up to a large crate, the player presses a button, and an animation starts playing where the character climbs up on to the crate. (all in first person view). So far I tried this with normal "First Person Controller" Prefab in Unity. My code so far: function OnTriggerStay(other : Collider){ if(other.tag == "GrabZone"){ if(Input.GetKeyDown("e")){ animation.Play("JumpToLedge"); } } } However when i use this on The FPC it will always play from the position the animation is created on. I also tried to create an empty game object, placing the FPC in there. Gives same effect. I also tried just animating the graphics of the FPC alone. This seems to work but since the Character Controller itself is not animated that stays onthe ground. So the whole FPC wont work anymore. Is there anyway i could let this animation play on the local position the player is on at that time? Or can you think of any other logical solution for a grab and climb?

  • Is learning C# as a first language a mistake?

    - by JuniorDeveloper1208
    I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

  • As a web designer, which language should I learn first for my feature career? (PHP or JavaScript) [closed]

    - by kdevs3
    Possible Duplicates: Best Programming Language for Web Development How can I choose a web development language? What language will you choose if you are going to build something big? What is the right option of programming languages and tools for building our website? What is the easiest web programing language at....? Well, I'm more of a basic web designer. I know the easy stuff pretty well. (Ya know, html, css) But I've been trying to take it to the next step and I'm contemplating about what I should learn that will help me out the most in my future web design/programming career, should it be JavaScript or maybe I should try to learn a back end programming language such as PHP. Lately, I have been hearing about a lot how JavaScript is so great and useful now, because of libraries such as jQuery and what possibility's it can bring by using Node.js and other frameworks. I've only learned the most basic of JavaScript and used some jQuery (mostly plugins) so i wouldn't know at all of what it can actually do. Would JS being so popular as it is now and useful, be a reason to stick with JavaScript and only learn it that for now? Or as a web designer, how important would it be to learn how to make a web application/website operate and functional, and know how to work with servers, etc? (Such as getting forms to work and sending data to the server and back) I've took a look at frameworks such as Code Igniter before, and looks really simple to get started with if I try to learn PHP, But I'm not sure how important it is for my career and what I would gain out of it. I'm asking because I can't decide what I should learn first. When I select it, I really want to take my time and learn the language. I don't want to spend time on learning multiple languages at the same time, so I need to pick wisely. I'm trying to turn the right direction so my career can hopefully be successful in the feature. (If money/gaining a job asked if its important, then its a yeah, it is a bit) I'm hoping I can get opinions and suggestions on this question, thanks for giving me your thoughts also.

  • What was the first consumer-oriented hardware/software solution?

    - by Maksee
    We all know the story of the personal computer as a consumer-oriented product. But I just thought that real end user solution should have appeared before that time. So a product that was probably expensive, but allowed using it as a service charging for it, for example computer-terminal for transport time-table access or game machine. On the other site, the video terminals as we know them appeared not so long ago. So if there was something like this, this could be hardware/software most likely offering no interactivity, but probably printing some information based on user actions.

More screen space thanks to no tabs:-  they tell this nonsense without think anything. if they really care about more screen space why they make tab  in 7,8,9. conclusion:- IE team make a research on how to promote IE9 better then they can beat chrome and Firefox. because IE9 not have anything good like customization , plug-in ,add-ons , personas , themes and many other thing like chrome and Firefox provided perhaps IE is outdated thing even everyone their can writing about these days that IE9 have this, have performance better then this… the main problem in IE is IE6. many developer hate them because many of their time goes for making site cross browser compatible. in 2009 they still have no blah like IE9 who they have today so they make a campaign for save IE6. the list they make is a joke. they show that everything in IE6 is perfect even everyone know the truth. they listed IE6 is high security. in 2011 their is a problem for IE9 promotion called IE6. because developer hate IE6 how they can promote IE9 very well. so destroy IE6 is only option for IE9 make promote better. so you can see they make two different different campaign and both are opposite of other. well  how we can believe in IE9. thanks for reading this post. what you thinking on it. have a idea or feedback reported them.
