  • Lighting Fast CMS, a Django based CMS. Any experiences?

    - by Melmacian
    I've just came across Lighting Fast CMS, which seems to be very promising Django based content management system. Documentation seem to be very good, even though it is still in beta stage. It also has very nice buildout based installation. Also core Components of it seem to be nicely decoupled. Does anyone have any experiences with it yet? How much one can customize it with extensions? How's extension development in general compared to Drupal or Plone? I'm hoping that I could do some projects with it instead of Plone or Drupal. Those both are great, but extending them ain't too nice. The project can be found here: http://www.lfcproject.com/

  • OMAP 3530: How fast can I toggle an IO?

    - by raj.tiwari
    I am putting together an application for OMAP 3530 SoC. This application will run some user interface code on embedded linux and invoke waveform generation code on the DSP. The DSP and Linux sides will interact over DSP/BIOS link. My questions are: What is the highest frequency at which my DSP-side code can toggle a GPIO line? If I want to toggle multiple GPIO lines at this hight rate, how fast can I go? Thanks for any insights. -Raj

  • How can I add forward class references used in the -Swift.h header?

    - by Bill
    I'm integrating Swift code into a large Objective-C project, but I'm running into problems when my Swift code refers to Objective-C classes. For example, suppose I have: An Objective-C class called MyTableViewController An Objective-C class called DeletionWorkflow I declared a Swift class as follows: class DeletionVC: MyTableViewController { let deleteWorkflow: DeletionWorkflow ... } If I now try to use this class by importing ProjectName-Swift.h into Objective-C code, I get undefined symbol errors for both MyTableViewController and DeletionWorkflow. I can fix the problem in that individual source file by importing DeletionWorkflow.h and MyTableViewController.h before I import ProjectName-Swift.h but this doesn't scale up to a large project where I want my Swift and Objective-C to interact often. Is there a way to add forward class references to ProjectName-Swift.h so that these errors don't occur when I try to use Swift classes from Objective-C code in my app?

  • Data structure in c for fast look-up/insertion/removal of integers (from a known finite domain)

    - by MrDatabase
    I'm writing a mobile phone based game in c. I'm interested in a data structure that supports fast (amortized O(1) if possible) insertion, look-up, and removal. The data structure will store integers from the domain [0, n] where n is known ahead of time (it's a constant) and n is relatively small (on the order of 100000). So far I've considered an array of integers where the "ith" bit is set iff the "ith" integer is contained in the set (so a[0] is integers 0 through 31, a[1] is integers 32 through 63 etc). Is there an easier way to do this in c?

  • Good .NET library for fast streaming / batching trigonometry (Atan)?

    - by Sean
    I need to call Atan on millions of values per second. Is there a good library to perform this operation in batch very fast. For example, a library that streams the low level logic using something like SSE? I know that there is support for this in OpenCL, but I would prefer to do this operation on the CPU. The target machine might not support OpenCL. I also looked into using OpenCV, but it's accuracy for Atan angles is only ~0.3 degrees. I need accurate results.

  • Should i use HttpResponse.End() for a fast webapp?

    - by acidzombie24
    HttpResponse.End() seems to throw an exception according to msdn. Right now i have the choice of returning a value to say end thread (it only goes 2 functions deep) or i can call end(). I know that throwing exceptions is significantly slower (read the comment for a C#/.NET test) so if i want a fast webapp should i consider not calling it when it is trivially easy to not call it? -edit- I do have a function call in certain functions and in the constructor in classes to ensure the user is logged in. So i call HttpResponse.End() in enough places although hopefully in regular site usage it doesn't occur too often.

  • SQL Server Query Slow from PHP, but FAST from SQL Mgt Studio - WHY???

    - by Ray
    I have a fast running query (sub 1 sec) when I execute the query in SQL Server Mgt Studio, but when I run the exact same query in PHP (on the same db instace) using FreeTDS v8, mssql_query(), it takes much longer (70+ seconds). The tables I'm hitting have an index on a date field that I'm using in the Where clause. Could it be that PHP's mssql functions aren't utilizing the index? I have also tried putting the query inside a stored procedure, then executing the SP from PHP - the same results in time difference occurs. I have also tried adding a WITH ( INDEX( .. ) ) clause on the table where that has the date index, but no luck either. Here's the query: SELECT 1 History, h.CUSTNMBR CustNmbr, CONVERT(VARCHAR(10), h.ORDRDATE, 120 ) OrdDate, h.SOPNUMBE OrdNmbr, h.SUBTOTAL OrdTotal, h.CSTPONBR PONmbr, h.SHIPMTHD Shipper, h.VOIDSTTS VoidStatus, h.BACHNUMB BatchNmbr, h.MODIFDT ModifDt FROM SOP30200 h WITH (INDEX (AK2SOP30200)) WHERE h.SOPTYPE = 2 AND h.DOCDATE >= DATEADD(dd, -61, GETDATE()) AND h.VOIDSTTS = 0 AND h.MODIFDT = CONVERT(VARCHAR(10), DATEADD(dd, -1*@daysAgo, GETDATE()) , 120 ) ;

  • How do I forward map a point in OpenCV using mapx & mapy?

    - by Charles
    Ultimately, I'm trying to determine the 3D location of a point I've identified in two cameras (using OpenCV 2.3.1, Windows 7, C++). I'm having trouble locating the 2D point for each camera from its mapx & mapy. I could not find in Bradski & Kaehler's OpenCV book how to do it. PROCESS calibrateCamera for each of the pair stereoCalibrate stereoRectify detect the blob I want to locate in 3D on each camera in 2D initUndistortRectifyMap for each camera Eventually, perspectiveTransform PROBLEM with 5: I have the x and y location of the point in the distorted and unrectified image for each camera(from #4) but I don't know how to get the undistorted and rectified x and y for each camera from the two maps initUndistortRectifyMap creates for each camera. I don't want to remap the whole image since I only want to learn the 3D location of one object for each frame. QUESTION: How do I forward map a point (get the undistorted and rectified x and y) with its two maps? Thanks for any help.

  • How do you design a database to allow fast multicolumn searching?

    - by Fletcher Moore
    I am creating a real estate search from RETS data, but this is a general question. When you have a variety of columns that you would like the user to be able to filter their search result by, how do you optimize this? For example, http://www.charlestonrealestateguide.com/listings.php has 16 or so optional filters. Granted, he only has up to 11,000 entries (I have the same data), but I don't imagine the search is performed with just a giant WHERE AND AND AND ... clause. Or is this typically accomplished with one giant multicolumn index? Newegg, Amazon, and countless others also have cool & fast filtering systems for large amounts of data. How do they do it? And is there a database optimization reason for the tendency to provide ranges instead of empty inputs, or is that merely for user convenience?

  • Fast, Vectorizable method of taking floating point number modulus of special primes?

    - by caffiend
    Is there a fast method for taking the modulus of a floating point number? With integers, there are tricks for Mersenne primes, so that its possible to calculate y = x MOD 2^31 without needing division. Can any similar tricks be applied for floating point numbers? Preferably, in a way that can be converted into vector/SIMD operations, or moved into GPGPU code. The primes I'm interested in would be 2^7 and 2^31, although if there are more efficient ones for floating point numbers, those would be welcome.

  • Safe to cast pointer to a forward-declared class to its true base class in C++?

    - by Matt DiMeo
    In one header file I have: #include "BaseClass.h" // a forward declaration of DerivedClass, which extends class BaseClass. class DerivedClass ; class Foo { DerivedClass *derived ; void someMethod() { // this is the cast I'm worried about. ((BaseClass*)derived)->baseClassMethod() ; } }; Now, DerivedClass is (in its own header file) derived from BaseClass, but the compiler doesn't know that at the time it's reading the definition above for class Foo. However, Foo refers to DerivedClass pointers and DerivedClass refers to Foo pointers, so they can't both know each other's declaration. First question is whether it's safe (according to C++ spec, not in any given compiler) to cast a derived class pointer to its base class pointer type in the absence of a full definition of the derived class. Second question is whether there's a better approach. I'm aware I could move someMethod()'s body out of the class definition, but in this case it's important that it be inlined (part of an actual, measured hotspot - I'm not guessing).

  • why does .replace method use forward slash characters to enclose the first argument?

    - by Phillip Dodd
    I am working through a book about Javascript and have encountered the following example of code designed to replace the value of the class attribute of a table header HTML element: th.className = th.className.replace(/asc/,"dsc"); th.className = th.className.replace(/dsc/,"asc"); Why is the first parameter of .replace, the current value of th.className, enclosed in forward slashes instead of quotation marks? Why not use quotation marks to enclose both parameters, not just the second one? Thank you in advance for any help given. First time posting, apologies if I duplicated a question despite searching the site before posting.

  • How can I emulate forward on 404 in jersey?

    - by koppor
    I have a picture on a given URL. The picture might need a referesh. I want to do the freshness-check at the time of the request. Therefore, I coded a jersey resource handling the request on the picture URL. It refreshes the picture on the filesystem if necessary. I do not want to re-code a caching mechansim, but rely on tomcat's implementation. Therefore, I would like to "forward" the request in the internal handler chain. I tried return new Viewable(sb.toString());, but a viewable is not a picture. What return type can I use? I could let the concrete picture reside on another URL and send a 307 (Temporary Redirect). Always sending that as answer seems odd to me. Related question: How to return a PNG image from Jersey REST service method to the browser

  • How does the default Camera iPhone app manages to save a photo so fast?

    - by worriorbg
    Hello everyone. So far I've managed to create an app for iPhone that takes multiple images with about a 3 second interval between each. I`m processing each image in a separate thread asynchronously and everything is great till it gets to the moment for saving the image on the iPhone disk. Then it takes about 12 seconds to save the image to the disk using JPEG representation. How does Apple do it, how do they manage to save a single image so fast to the disk is there a trick they are using? I saw that the animations distract the user for a while, but still the time needed is below 12 seconds! Thanks in advance.

  • Why are most really fast servers written in C instead of C++?

    - by orokusaki
    I'm trying to decide which to learn and I've read all the "Which is better" questions/arguments, so I thought I'd get your take on something more specific. Is there a platform dependency issue that C++ developers run into with such applications? Or, is it because there are more C developers out there than C++? I also noticed that many more third party C modules exist for Python even thought C++ modules are supported. From what I've read on different threads the consensus is that C++ is easier and faster to write, and runs just as fast. Am I missing something really big. Examples: NGINX APE (comet server) Apache

  • Forward a call to a webservice to another webservice?

    - by Luhmann
    If I have an https webservice behind a firewall on a machine (A) that I cannot access, but access to a machine on the same network (B), from where I can call the webservice on machine A. What is the best way of talking with the webservice on machine A, from the outside via machine B (that I access via VPN)? I can obviously create a service with a matching interface on machine B, and call the methods on the webservice on machine A, and return the result. But I fear for the overhead. Is there another way? Can i somehow forward the request?

  • Is Android (read typical devices) fast enough for a game that requires plotting pixel by pixel rather than blitting

    - by mP
    i have an idea for an Android game which is a little different from the typical game that usually moves sprites(bitmaps) around the screen. Id want to plot lots of little pixels to create my visuals. PROS no bitmaps required pixel plotting of stuff like "fire" can react to wind. no need to scale bitmaps, works w/ any screen res (lets pretend device can handle more drawing because its got a bigger screen). CONS slower to plot pixels than blit bitmaps need lot of animation frames. WISHES id like to update my game in real time, more is better 30fps is good but not essential, 15fps is enough. PERFORMANCE Q... Is the typical Android device fast enough to plot say half a screenful of pixels w/ a default background ? if full screen is not practical what window size should be able to handle such refreshes

  • Is there any way that I can draw fast a chart with too many series? [on hold]

    - by Maryam Bagheri
    I have a project that need to draw a fast chart with many series. I must change start position of drawing to a favor position when user want. .Net Chart is slow in lots of series. I wanted to use this library: http://www.codeproject.com/Articles/32836/A-simple-C-library-for-graph-plotting?msg=4109664#xx4109664xx but loading speed is too slow when count of series increases. When I plot the chart, I must invalidate the chart for updates, drawing speed will be too slow if there are too many series. I need at least 900 series in a chart for this project. I wanted to use multiple layer series to decrease invalidate rate with the idea: http://www.codeproject.com/Articles/84833/Drawing-multiple-layers-without-flicker I do not know this idea would be helpful. I tested LightningChart control but it could not help me.

  • How online-game clients are able to exchange data through internet so fast?

    - by Kirzilla
    Hello, Let's imagine really simple game... We have a labirinth and two players trying to find out exit in real time through internet. On every move game client should send player's coordinates to server and accept current coordinates of another client. How is it possible to make this exchange so fast (as all modern games do). Ok, we can use memcache or similar technology to reduce data mining operations on server side. We can also use fastest webserver etc., but we still will have problems with timings. So, the questions are... What protocol game clients are usually using for exchanging information with server? What server technologies are coming to solve this problem? What algorithms are applied for fighting with delays during game etc. PS: Sorry for my English and I hope that my question is clear. Thank you.

  • Setting up Ubuntu Server as a Router with DHCPD and 3 Ethernet devices

    - by cengbrecht
    My configuration: Ubuntu 12.04 DHCP3-server eth0, eth1, eth2 Edit: removed br0&br1 eth0 is the external connection eth1 & eth2 are the internal network eth1 and eth2 are supposed to be seperate networks of student/teachers respectivly. What I would like to have is the internet from external device bridged to device 1 and 2, with the DHCP server controlling the two internal devices. Its already working with DHCP, the part I am stuck on is bridging for internet. I have setup a script that I found here: Router With the original script he linked here: Ubuntu Router Guide echo -e "\n\nLoading simple rc.firewall-iptables version $FWVER..\n" IPTABLES=/sbin/iptables #IPTABLES=/usr/local/sbin/iptables DEPMOD=/sbin/depmod MODPROBE=/sbin/modprobe EXTIF="eth0" INTIF="eth1" INTIF2="eth2" echo " External Interface: $EXTIF" echo " Internal Interface: $INTIF" echo " Internal Interface: $INTIF2" EXTIP=`ifconfig $EXTIF | grep 'inet addr:' | sed 's#.*inet addr\:\([0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\).*#\1#g'` echo " External IP: $EXTIP" #====================================================================== #== No editing beyond this line is required for initial MASQ testing == The rest of the script below this is as is. I can get ip from the eth1 & eth2 devices, and my computer can see them, and them it, however, internet is not being passed through. If you need more information please just let me know. EDIT: So I had a 255.255.254.0 network, I believe that was causing the issue. Not sure if it will matter on the second card, I will test later. After changing the subnet to 255.255.255.0 the pings will pass through, however, I cannot get DNS requests to pass?

  • Fast window switching without Alt-Tab or Command-Tab?

    - by Sridhar Ratnakumar
    Alt-Tab or Command-Tab can sometimes be slow, especially when you have many windows open and you frequently switch to only a few of those windows. How do you work around this problem -- any tool to switch to desired windows (most frequently accessed) directly, other than tapping the Alt-Tab combination multiple times? Note: This should work on Windows 7, Linux and Mac. Update: Please post your keyboard-shortcut solutions (using the mouse cannot be any faster - especially when you were touch-typing/writing-code before switching to a window).

  • Can / should I prevent my domain controller doing forward lookups for remote users?

    - by markmnl
    I have a Windows Server 2003 server in the office. I VPN into the LAN remotely. My VPN has a virtual NIC with the Windows Server as the primary DNS since it is a domain controller. When connected to the VPN and I do a nslookup or simply browse the web my VPN's DNS (the office's Windows Server) provides the DNS answers - I beleive becuase it has DNS forwarders so queries it cant answer it forwards and then relays the answer. This is the desired behaviour for workstations in the office (they should query their domain controller first). However for remote VPN users this is not desirable - I do not want my remote office's server to answer DNS queries it is not the authority of (which happends to be 192.168.x.x). Is there any way I can configure this?

  • How can I forward ALL traffic over a site-to-site VPN on Cisco ASA?

    - by Scott Clements
    Hi There, I currently have two Cisco ASA 5100 routers. They are at different physical sites and are configured with a site-to-site VPN which is active and working. I can communicate with the subnets on either site from the other and both are connected to the internet, however I need to ensure that all the traffic at my remote site goes through this VPN to my site here. I know that the web traffic is doing so as a "tracert" confirms this, but I need to ensure that all other network traffic is being directed over this VPN to my network here.
