• Best approach to get clicked objects from a display list (2D)

  - by Ixx

  I'm implementing a display list to manage my visuals on screen. I want to know which object is clicked. My objects already have z-order variable. With my current knowledge (almost nothing) the only thing which comes to my mind is make a linear search and get all the objects which contains the clicked point. And then select the object with the highest z-order. But I know there are far better approaches. I think it's something with trees (binary search?). - container display objects and search recursively? just don't know where to start looking, for this concrete case. Any hint link or concrete solution is welcome.

• Is it possible to get dragging working on a Macbook multi-touch touch pad?

  - by lhahne

  I have a Macbook 5,1. That is to say that it is the only 13 inch aluminium Macbook as the later revisions were renamed Macbook Pro. Two-finger scrolling seems to work fine but dragging doesn't work. In OsX this works so that you point an object, click and keep your finger pressed on the touch pad while slide another finger to move the cursor. This causes weird and undefined behavior in Ubuntu as it seems the driver doesn't recognize this as dragging. Any ideas?

• Data architecture for event log metrics?

  - by elliot42

  My service has a large ongoing number of user events, and we would like to do things like "count occurrence of event type T since date D." We are trying to make two basic decisions: What to store? Storing every event vs. only storing aggregates (Event log style) log every event and count them later, vs. (Time-series style) store a single aggregated "count of event E for date D" for every day Where to store the data In a relational database (particularly MySQL) In a non-relational (NoSQL) database In flat log files (collected centrally over the network via syslog-ng) What is standard practice / where can I read more about comparing the different types of systems? Additional details: The total event stream is large, potentially hundreds of thousands of entries per day But our current need is only to count certain types of events within it We don't necessarily need real-time access to the raw data or aggregation results IMHO, "log all events to files, crawl them at a later time to filter and aggregate the stream" is a pretty standard UNIX Way, but my Rails-y compatriots seem to think that nothing is real unless it's in MySQL.

• How selective do we need to be for an index to be used?

  - by TiborKaraszi

  You know the answer already: It depends. But I often see some percentage value quoted and the point of this post is to show that there is no such percentage value. To get the most out of this blog post, you should understand the basic structure for an index, i.e. how the b+ tree look like. You should also understand the difference between a clustered and a non-clustered index. In essence, you should be able to visualize these structures and searches through them as you read the text. If you find...(read more)

• Hard disk error

  - by Nadim A. Hachem

  I got this error during installation. "The installer encountered an error copying files to the hard disk: [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." how can i fix this and what does it mean specifically? i'm installing via usb so it can't be the CD. the laptop is recent so it cant be an old HD.

• Intel dément trouver Windows 8 pas assez finalisé, l'OS serait même l'une des meilleures choses qui soient arrivées à la société

  Windows 8 ne serait pas encore finalisé pour le patron d'Intel qui estime que des améliorations sont encore nécessaires Microsoft va officiellement lancer Windows 8 le 26 octobre avec une nouvelle génération de tablettes et PC fonctionnant sous le système d'exploitation. Mais, il semblerait que l'OS ne soit pas encore totalement finalisé. C'est en tout cas ce que pense Paul Otellini, le PDG d'Intel, selon un article Bloomberg. Le patron du constructeur de microprocesseurs qui est le partenaire le plus proche de Microsoft aurait déclaré lors d'une réunion privée avec son équipe de Taïwan que Windows 8 va être lancé avant d'être finalisé. D'un point de vu comm...

• How to change the state of a singleton in runtime

  - by user34401

  Consider I am going to write a simple file based logger AppLogger to be used in my apps, ideally it should be a singleton so I can call it via public class AppLogger { public static String file = ".."; public void logToFile() { // Write to file } public static log(String s) { AppLogger.getInstance().logToFile(s); } } And to use it AppLogger::log("This is a log statement"); The problem is, what is the best time I should provide the value of file since it is a just a singleton? Or how to refactor the above code (or skip using singleton) so I can customize the log file path? (Assume I don't need to write to multiple at the same time) p.s. I know I can use library e.g. log4j, but consider it is just a design question, how to refactor the code above?

• WHM local/external mail server confusion

  - by BWRic

  We host several websites on the same server using WHM but this seems to confuse the mail routing when someone has their own external mail servers - it looks locally. We have our own email accounts hosted on the server. When creating an account for a client on the same server WHM adds the default entries to the DNS for that account. However this client has their own mail servers elsewhere. But when sending them an email it never reaches that external server - it just sees the local, incorrect one. I realise I can update my DNS to point to the external server, but this means I am copying their settings and if they are changed, then I will also need to update mine. Are there some settings I can use to force it to use the external servers without having to copy the settings.

• Bomb timer adventure game win32 c++ [on hold]

  - by user3491746

  I'm working on an adventure game in win32 and opengl for my 2nd year university project for class. I am pretty much finished my game but I'm stuck on the concept of how to program a timer which outputs hh : mm : ss -- but which countdown, not up. I've made a clock which counts up using vector matrices and the segxseg matrix algorithm but I cannot figure out how to make a clock (it can be simple even text using wsprintf) that counts down in that format. Can anyone possible give me an example or some literature that I can read on how to do this? Please dont suggest for me to use another environment, I've already been working here for 2 months on this game, and I'm pretty much done so i'm at no point to switch over. Can anyone show me how I can take a shot at this component of my project? Thanks a bunch! Anything that I can get is appreciated.

• Regulating outgoing traffic on ubuntu VM

  - by DazSlayer

  I am making a virtual network setup for my high school cybersecurity team to practice. I am connecting all the VMs together through a VPN and then people who are practicing will VPN in and ssh/remote desktop into the different VMs. The problem is that for practicing, they will need root access into the VMs and because the VMs are connecting to my personal network, the VMs pose a security risk to my personal network. Is there any way in either VMWare or VirtualBox or even making an unchangeable iptable (I can make all the windows VMs go thru a linux VM) to prevent people from connecting to my local network via the VM?

• Is programming as a profession in a race to the bottom?

  - by q303

  It seems to me that the programming industry is in a race to the bottom. If we take the practices of: Not taking time to implement best practices Using other's people code as much as possible (custom code as a liability) Using increasingly higher level languages to improve productivity GUI based development "tools" that greatly simplify "programming" and do not require people to understand the plumbing behind the code These things imply to me that we are in a race to becoming like any other office worker. It is in the employer's interest for things to not require skill (easier to replace), for things to be prebuilt (less project time). My point here is that a) is there a misalignment between skill and the economic interests of the employer? and b) if there is, how do you mitigate it to enforce professional standards?

• I'm a premature optimizer

  - by Matthew Day

  I work in a small sized software/web development company. I have gotten into the habit of optimizing prematurely, I know it is evil and promotes bad code... But I have been working at this firm for a long while and I have deemed this as a necessary evil. It has never caused me an issue so far in the past, but it might if I get partners or a successor. The point of this long-winded speech is that, should I change my evil practices to 'save face' and to help out in the future?

• Problems with No-IP redirecting

  - by user171156

  I am setting up a webserver on my ubuntu desktop 13.04, everything is working fine except; When trying to access the server through the external host using no-ip, it gives the original index created by apache on setup. While when I try to connect to the server via my real IP address from externally, it goes to the correct index. I have been trying to figure out what the issue is on this problem as nothing is working because of that bad redirect, I'm wondering if anyone of you could help me out, or advise me in the right path. Thank you very much! PS; If more info needed I'll provide, but this should explain it all.

• Moving OVD from Test to Production

  - by mark.wilcox

  Customer asked support "How to move a test OVD server to production". There is a couple of ways to do this. One way is to clone the environment: http://download.oracle.com/docs/cd/E15523_01/core.1111/e10105/testprod.htm#CH... Another way - which is particularly useful if you want to push configuration from a parent OVD server to children in a cluster: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10046/basic_server_set... Note if you use the second option and you have any data in a Local Store Adapter - you may also need to use the oidcmprec tool to synchronize that data: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10029/replic_mng_mon.h...

• Detecting right-click on XAML GridView control item

  - by mbrit

  Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

• How best to merge/sort/page through tons of JSON arrays?

  - by Joshiatto

  Here's the scenario: Say you have millions of JSON documents stored as text files. Each JSON document is an array of "activity" objects, each of which contain a "created_datetime" attribute. What is the best way to merge/sort/filter/page through these activities via a web UI? For example, say we want to take a few thousand of the documents, merge them into a gigantic array, sort the array by the "created_datetime" attribute descending and then page through it 10 activities at a time. Also keep in mind that roughly 25% of these JSON documents are updated every day, and updates have to make it into the view within 5 minutes. My first thought is to parse all of the documents into an RDBMS table and then it would just be a simple query such as "select top 10 name, created_datetime from Activity where user_id=12345 order by created_datetime desc". Some have suggested I use NoSQL techniques such as hadoop or map/reduce instead. How exactly would this work? For more background, see: Why is NoSQL better for this scenario?

• Welcome to our Friday tips series!

  - by Chris Kawalek

  Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

• RTOS experience

  - by Subbu

  I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction.

• Ubuntu partition won't display on screen

  - by Danny

  I installed ggobi on my MacBook Pro, and it wasn't working right. I looked up some information, and found this site: Gtk Warning: Cannot open display I followed the vague instructions, but I think I just typed export DISPLAY=:0 directly into my terminal (I'm still in my Mac partition at this point). Fast forward a few days, and I try to go into my Ubuntu partition. It only gives me command line options. I remember my reckless input from a few days back, and I'm certain that it is the issue. My problem is that I have no idea how to get my previous display settings back. My Mac partition seems unaffected, but it'd be nice to get back into my Ubuntu partition. My last resort is completely reverting my computer to my most recent backup before I changed it, but if anyone out there knows how to fix this, I'd greatly appreciate it. Thanks in advance.

• How to fix slow wireless with Intel 4965 AGN? [closed]

  - by mikewhatever

  Possible Duplicate: Slow wireless with an Intel 4965 We run Ubuntu 12.04, 32bit, with the current kernel 3.2.27-generic on an MSI EX700. I've already added the 11n_disable=1 tweek, without whcih, wireless has been unusable. Now, it works OK, but speedtest shows: Windows XP - down 11.68mbps, up 2.07mbps Ubuntu 12.04 - down 2.06mbps up 2.0mbps We've disabled ipv6, tried static and dinamic IPs, tried both swcrypto=0 and swcrypto=1 options, none of whcih made any difference.

• Skype 4.2 crashes and bugs on 13.10

  - by Juhani Taylor

  I've installed Skype and it appears to work fine right up until the point where I try to call someone. If I try to video call someone then the programme freezes and I have to force quit. I've tried several 'solutions' I've found on various forums but none seem to work. Now, when I try to call the Echo service as a test to see if the bug's fixed, it seems to connect and start the non-video call, except that it's completely silent. No audio at all. Any help? It seems to be 2 separate issues: audio and generic crashing. Anyone come across these and found solutions?
