  • Django - How to do CSFR on public pages? Or, better yet, how should it be used period?

    - by orokusaki
    After reading this: http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#how-to-use-it I came to the conclusion that it is not valid to use this except for when you trust the person who is using the page which enlists it. Is this correct? I guess I don't really understand when it's safe to use this because of this statement: This should not be done for POST forms that target external URLs, since that would cause the CSRF token to be leaked, leading to a vulnerability. The reason it's confusing is that to me an "external URL" would be on that isn't part of my domain (ie, I own www.example.com and put a form that posts to www.spamfoo.com. This obviously can't be the case since people wouldn't use Django for generating forms that post to other people's websites, but how could it be true that you can't use CSRF protection on public forms (like a login form)?

  • SSRS 2005 - Usability analysis - Is SSRS a good option for this scenario?

    - by Sach
    How practical is it to consider SSRS 2005 or SSRS 2008 as a reporting solution for a report that has to show reports with millions of records (records vary from 3 to 10 million)? Is there any threshold on the size of report in SSRS? How do I know that for a huge report, wheather SSRS will consume the whole memory and start paging the operations to disk or it will give a memory leak error? Even if I keep on increasing the memory how can I be sure that certain memory will be sufficient for such huge reports for the report server? All the above questions are haunting me because I have a dedicated report server with a decent hardware and OS configuration (8 processors, 8GB RAM, 64 bit OS and 64 bit SQL Server 2005). Still my report with around 2 million records is taking more than 6 minutes and going from one page to another takes 3 minutes!!! My datasource is on separate server and when I execute only the stored proc there, it returns the results in less than 2 minutes.

  • ASP.NET MVC OutputCache with POST Controller Actions

    - by Maxim Z.
    I'm fairly new to using the OutputCache attribute in ASP.NET MVC. Static Pages I've enabled it on static pages on my site with code such as the following: [OutputCache(Duration = 7200, VaryByParam = "None")] public class HomeController : Controller { public ActionResult Index() { //... If I understand correctly, I made the whole controller cache for 7200 seconds (2 hours). Dynamic Pages However, how does it work with dynamic pages? By dynamic, I mean where the user has to submit a form. As an example, I have a page with an email form. Here's what that code looks like: public class ContactController : Controller { // // GET: /Contact/ public ActionResult Index() { return RedirectToAction("SubmitEmail"); } public ActionResult SubmitEmail() { //In view for CAPTCHA: <%= Html.GenerateCaptcha() %> return View(); } [CaptchaValidator] [AcceptVerbs(HttpVerbs.Post)] public ActionResult SubmitEmail(FormCollection formValues, bool captchaValid) { //Validate form fields, send email if everything's good... if (isError) { return View(); } else { return RedirectToAction("Index", "Home"); } } public void SendEmail(string title, string name, string email, string message) { //Send an email... } } What would happen if I applied OutputCache to the whole controller here? Would the HTTP POST form submission work? Also, my form has a CAPTCHA; would that change anything in the equation? In other words, what's the best way to approach caching with dynamic pages? Thanks in advance.

  • android compile error: could not reserve enough space for object heap

    - by moonlightcheese
    I'm getting this error during compilation: Error occurred during initialization of VM Could not create the Java virtual machine. Could not reserve enough space for object heap What's worse, the error occurs intermittently. Sometimes it happens, sometimes it doesn't. It seems to be dependent on the amount of code in the application. If I get rid of some variables or drop some imported libraries, it will compile. Then when I add more to it, I get the error again. I've included the following sources into the application in the [project_root]/src/ directory: org.apache.httpclient (I've stripped all references to log4j from the sources, so don't need it) org.apache.codec (as a dependency) org.apache.httpcore (dependency of httpclient) and my own activity code consisting of nothing more than an instance of HttpClient. I know this has something to do with the amount of memory necessary during compile time or some compiler options, and I'm not really stressing my system while i'm coding. I've got 2GB of memory on this Core Duo laptop and windows reports only 860MB page file usage (haven't used any other memory tools. I should have plenty of memory and processing power for this... and I'm only compiling some common http libs... total of 406 source files. What gives? edit (4/30/2010-18:24): Just compiled some code where I got the above stated error. I closed some web browser windows and recompiled the same exact code with no edits and it compiled with no issue. this is definitely a compiler issue related to memory usage. Any help would be great.... because I have no idea where to go from here. Android API Level: 5 Android SDK rel 5 JDK version: 1.6.0_12 Sorry I had to repost this question because regardless of whether I use the native HttpClient class in the Android SDK or my custom version downloaded from apache, the error still occurs.

  • Easy way to observe user activity - how improve my database structure.

    - by Thomas
    Welcome, I need some advise to improve perfomence my web application. In the begin I had this structure of database: USER -id (Primary Key) -name -password -email .... PROFILE -user Primary Key, Foreign Key (USER) -birthday -region -photoFile ... PAGES -id (Primary Key) -user Foreign Key(USER) -page -date COMMENTS -id (Primary Key) -user Foreign Key(USER) -page Foreign Key(PAGE) -comment -date FAVOURITES_PAGES -id (Primary Key) -user Foreign Key(USER) -favourite_page Foreign Key(PAGE) -date but now one of the most important page of website is observatory, when everyone can observe activity others users. So I need select all pages, comments and favourites pages some users and display it in one list, sorted by date. For better perfomance (I think) I changed my structure to this: table USER and PROFILE without changes ACTIVITY (additional table- have common fields: user,date) -id (Primary Key) -user Foreign Key(USER) -date -page Foreign Key(PAGE) -comment Foreign Key(COMMENTS) -favourite_page Foreign Key(FAVOURITES_PAGES) PAGES -id (Primary Key) -page COMMENTS -id (Primary Key) -page Foreign Key(PAGE) -comment FAVOURITES_PAGES -id (Primary Key) -favourite_page Foreign Key(PAGE) So now it is very easy get sorted records from all tables. But I have no only foreign key to PAGES, COMMENTS and FAVOURITES_PAGES in ACTIVITY table - there is about ten Foreign Key fields and in one record only one have value, others have None: ACTIVITY id user date page comment ... 1 2 2010-02-23 None 1 2 1 2010-02-21 1 None .... It is corect solution. When I display about 40 records in one page (pagination) I must wait about one secound, but database is almost emty (a few users and about 100 records in others tables). It is depends on amount records per page - I have checked it, but why it takes too long time, becouse of relationships? The website is built in Python/Django. Any advices/opinion?

  • Delphi: Alternative to using Assign/ReadLn for text file reading

    - by Ian Boyd
    i want to process a text file line by line. In the olden days i loaded the file into a StringList: slFile := TStringList.Create(); slFile.LoadFromFile(filename); for i := 0 to slFile.Count-1 do begin oneLine := slFile.Strings[i]; //process the line end; Problem with that is once the file gets to be a few hundred megabytes, i have to allocate a huge chunk of memory; when really i only need enough memory to hold one line at a time. (Plus, you can't really indicate progress when you the system is locked up loading the file in step 1). The i tried using the native, and recommended, file I/O routines provided by Delphi: var f: TextFile; begin Assign(filename, f); while ReadLn(f, oneLine) do begin //process the line end; Problem withAssign is that there is no option to read the file without locking (i.e. fmShareDenyNone). The former stringlist example doesn't support no-lock either, unless you change it to LoadFromStream: slFile := TStringList.Create; stream := TFileStream.Create(filename, fmOpenRead or fmShareDenyNone); slFile.LoadFromStream(stream); stream.Free; for i := 0 to slFile.Count-1 do begin oneLine := slFile.Strings[i]; //process the line end; So now even though i've gained no locks being held, i'm back to loading the entire file into memory. Is there some alternative to Assign/ReadLn, where i can read a file line-by-line, without taking a sharing lock? i'd rather not get directly into Win32 CreateFile/ReadFile, and having to deal with allocating buffers and detecting CR, LF, CRLF's. i thought about memory mapped files, but there's the difficulty if the entire file doesn't fit (map) into virtual memory, and having to maps views (pieces) of the file at a time. Starts to get ugly. i just want Assign with fmShareDenyNone!

  • Help with Perl persistent data storage using Data::Dumper

    - by stephenmm
    I have been trying to figure this out for way to long tonight. I have googled it to death and none of the examples or my hacks of the examples are getting it done. It seems like this should be pretty easy but I just cannot get it. Here is the code: #!/usr/bin/perl -w use strict; use Data::Dumper; my $complex_variable = {}; my $MEMORY = "$ENV{HOME}/data/memory-file"; $complex_variable->{ 'key' } = 'value'; $complex_variable->{ 'key1' } = 'value1'; $complex_variable->{ 'key2' } = 'value2'; $complex_variable->{ 'key3' } = 'value3'; print Dumper($complex_variable)."TEST001\n"; open M, ">$MEMORY" or die; print M Data::Dumper->Dump([$complex_variable], ['$complex_variable']); close M; $complex_variable = {}; print Dumper($complex_variable)."TEST002\n"; # Then later to restore the value, it's simply: do $MEMORY; #eval $MEMORY; print Dumper($complex_variable)."TEST003\n"; And here is my output: $VAR1 = { 'key2' => 'value2', 'key1' => 'value1', 'key3' => 'value3', 'key' => 'value' }; TEST001 $VAR1 = {}; TEST002 $VAR1 = {}; TEST003 Everything that I read says that the TEST003 output should look identical to the TEST001 output which is exactly what I am trying to achieve. What am I missing here? Should I be "do"ing differently or should I be "eval"ing instead and if so how? Thanks for any help...

  • Filtering Wikipedia's XML dump: error on some accents

    - by streetpc
    I'm trying to index Wikpedia dumps. My SAX parser make Article objects for the XML with only the fields I care about, then send it to my ArticleSink, which produces Lucene Documents. I want to filter special/meta pages like those prefixed with Category: or Wikipedia:, so I made an array of those prefixes and test the title of each page against this array in my ArticleSink, using article.getTitle.startsWith(prefix). In English, everything works fine, I get a Lucene index with all the pages except for the matching prefixes. In French, the prefixes with no accent also work (i.e. filter the corresponding pages), some of the accented prefixes don't work at all (like Catégorie:), and some work most of the time but fail on some pages (like Wikipédia:) but I cannot see any difference between the corresponding lines (in less). I can't really inspect all the differences in the file because of its size (5 GB), but it looks like a correct UTF-8 XML. If I take a portion of the file using grep or head, the accents are correct (even on the incriminated pages, the <title>Catégorie:something</title> is correctly displayed by grep). On the other hand, when I rectreate a wiki XML by tail/head-cutting the original file, the same page (here Catégorie:Rock par ville) gets filtered in the small file, not in the original… Any idea ? Alternatives I tried: Getting the file (commented lines were tried wihtout success): FileInputStream fis = new FileInputStream(new File(xmlFileName)); //ReaderInputStream ris = ReaderInputStream.forceEncodingInputStream(fis, "UTF-8" ); //(custom function opening the stream, reading it as UFT-8 into a Reader and returning another byte stream) //InputSource is = new InputSource( fis ); is.setEncoding("UTF-8"); parser.parse(fis, handler); Filtered prefixes: ignoredPrefix = new String[] {"Catégorie:", "Modèle:", "Wikipédia:", "Cat\uFFFDgorie:", "Mod\uFFFDle:", "Wikip\uFFFDdia:", //invalid char "Catégorie:", "Modèle:", "Wikipédia:", // UTF-8 as ISO-8859-1 "Image:", "Portail:", "Fichier:", "Aide:", "Projet:"}; // those last always work

  • What happens after a packet is captured?

    - by Rayne
    Hi all, I've been reading about what happens after packets are captured by NICs, and the more I read, the more I'm confused. Firstly, I've read that traditionally, after a packet is captured by the NIC, it gets copied to a block of memory in the kernel space, then to the user space for whatever application that then works on the packet data. Then I read about DMA, where the NIC directly copies the packet into memory, bypassing the CPU. So is the NIC - kernel memory - User space memory flow still valid? Also, do most NIC (e.g. Myricom) use DMA to improve packet capture rates? Secondly, does RSS (Receive Side Scaling) work similarly in both Windows and Linux systems? I can only find detailed explanations on how RSS works in MSDN articles, where they talk about how RSS (and MSI-X) works on Windows Server 2008. But the same concept of RSS and MSI-X should still apply for linux systems, right? Thank you. Regards, Rayne

  • Htaccess rewrite rule .aspx to .php

    - by Markus Ossi
    Background: I have a website that has been built with ASP.NET 2.0 and is on Windows hosting. I now have to rewrite my site in PHP and move it into Linux hosting. I have a lot of incoming links to my site from around the web that point directly into the old .aspx-pages. The site itself is very simple, one dynamic page and five static ones. I saved the static .aspx pages as .php-pages and rewrote the dynamic page in PHP. The dynamic page is called City.aspx and I have written it in PHP and it is now called City.php. On my old Windows hosting, I used ASP.NET's URL mapping for friendly URL. For example, incoming URL request for Laajakaista/Ypaja.aspx was mapped into City.aspx?CityID=981. My goal: To redirect all human visitors and search engines looking for the old .aspx pages into the new .php pages. I am thinking that the easiest way to redirect visitors into new pages will be by making a redirect, where all requests for .aspx-files will be redirected into .php filetypes. So, if someone asks for MYSITE/City.aspx?CityID=5, they will be taken into MYSITE/City.php?CityID=5 instead. However, I am having a lot of trouble getting this to work. So far this is what I have found: rewriterule ^([.]+)\.aspx$ http://www.example.com/$1.php [R=301,L] However, I think this can not handle the parameters after the filetype and I am also not quite sure what to put on front. To make things a bit more complicated, at my previous site I used friendly URL's so that I had a huge mapping file with mappings like this: <add url="~/Laajakaista/Ypaja.aspx" mappedUrl="~/City.aspx?CityID=981" /> <add url="~/Laajakaista/Aetsa.aspx" mappedUrl="~/City.aspx?CityID=988" /> <add url="~/Laajakaista/Ahtari.aspx" mappedUrl="~/City.aspx?CityID=989" /> <add url="~/Laajakaista/Aanekoski.aspx" mappedUrl="~/City.aspx?CityID=992" /> I tried to make a simple redirect like this: Redirect 301 Laajakaista/Aanekoski.aspx City.php?CityID=992 but was not able to get it to work. I ended up with an internal server error and a 50k .htaccess-file... Any help is greatly appreciated.

  • MBR Booting from DOS

    - by eflukx
    For a project I would like to invoke the MBR on the first harddisk directly from DOS. I've written a small assembler program that loads the MBR in memory at 0:7c00h an does a far jump to it. I've put my util on a bootable floppy. The disk (HD0, 0x80) i'm trying to boot has a TrueCrypt boot loader on it. It shows up the TrueCrypt screen, but after typing in the password it crashes the system. When I run my little utlility (w00t.com) on a normal WinXP machine it seams to crash immedealty. Apparently I'm forgetting some crucial stuff the BIOS normally does, my guess is it's something trivial. Can someone with better bare-metal DOS and BIOS experience help me out? Heres my code: .MODEL tiny .386 _TEXT SEGMENT USE16 INCLUDE BootDefs.i ORG 100h start: ; http://vxheavens.com/lib/vbw05.html ; Before DOS has booted the BIOS stores the amount of usable lower memory ; in a word located at 0:413h in memory.

  • Admin interface in Rails

    - by yuval
    I have an admin controller located in controllers/admin/admin_controller.rb I also have a pages controller located in controllers/admin/pages_controller.rb pages_controller.rb inherits from admin_controller.rb in routes.rb, I have an admin namespace as such: map.namespace :admin do |admin| admin.resources :pages end I want the admin have basic CRUD functionality in pages_controller.rb (I know how to do that) I want the index and show methods to be available to front-end users I would like the show and index actions to use separate views, but the same code. Questions: Should I create a new pages_controller for the front-end, or share the methods index and show? If share, how would I display separate views depending on whether the url is /admin/pages or /pages If share, should I place pages_controller in /controllers/admin (where it is now) or just in /controllers? Thank you very much.

  • Solving problems involving more complex data structures with CUDA

    - by Nils
    So I read a bit about CUDA and GPU programming. I noticed a few things such that access to global memory is slow (therefore shared memory should be used) and that the execution path of threads in a warp should not diverge. I also looked at the (dense) matrix multiplication example, described in the programmers manual and the nbody problem. And the trick with the implementation seems to be the same: Arrange the calculation in a grid (which it already is in case of the matrix mul); then subdivide the grid into smaller tiles; fetch the tiles into shared memory and let the threads calculate as long as possible, until it needs to reload data from the global memory into shared memory. In case of the nbody problem the calculation for each body-body interaction is exactly the same (page 682): bodyBodyInteraction(float4 bi, float4 bj, float3 ai) It takes two bodies and an acceleration vectors. The body vector has four components it's position and the weight. When reading the paper, the calculation is understood easily. But what is if we have a more complex object, with a dynamic data structure? For now just assume that we have an object (similar to the body object presented in the paper) which has a list of other objects attached and the number of objects attached is different in each thread. How could I implement that without having the execution paths of the threads to diverge? I'm also looking for literature which explains how different algorithms involving more complex data structures can be effectively implemented in CUDA.

  • Performance required to improve Windows Experience Index?

    - by Ian Boyd
    Is there a guide on the metrics required to obtain a certain Windows Experience Index? A Microsoft guy said in January 2009: On the matter of transparency, it is indeed our plan to disclose in great detail how the scores are calculated, what the tests attempt to measure, why, and how they map to realistic scenarios and usage patterns. Has that amount of transparency happened? Is there a technet article somewhere? If my score was limited by my Memory subscore of 5.9. A nieve person would suggest: Buy a faster RAM Which is wrong of course. From the Windows help: If your computer has a 64-bit central processing unit (CPU) and 4 gigabytes (GB) or less random access memory (RAM), then the Memory (RAM) subscore for your computer will have a maximum of 5.9. You can buy the fastest, overclocked, liquid-cooled, DDR5 RAM on the planet; you'll still have a maximum Memory subscore of 5.9. So in general the knee-jerk advice "buy better stuff" is not helpful. What i am looking for is attributes required to achieve a certain score, or move beyond a current limitation. The information i've been able to compile so far, chiefly from 3 Windows blog entries, and an article: Memory subscore Score Conditions ======= ================================ 1.0 < 256 MB 2.0 < 500 MB 2.9 <= 512 MB 3.5 < 704 MB 3.9 < 944 MB 4.5 <= 1.5 GB 5.9 < 4.0GB-64MB on a 64-bit OS Windows Vista highest score 7.9 Windows 7 highest score Graphics Subscore Score Conditions ======= ====================== 1.0 doesn't support DX9 1.9 doesn't support WDDM 4.9 does not support Pixel Shader 3.0 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 7.9 Windows 7 highest score Gaming graphics subscore Score Result ======= ============================= 1.0 doesn't support D3D 2.0 supports D3D9, DX9 and WDDM 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 6.0-6.9 good framerates (e.g. 40-50fps) at normal resoltuions (e.g. 1280x1024) 7.0-7.9 even higher framerates at even higher resolutions 7.9 Windows 7 highest score Processor subscore Score Conditions ======= ========================================================================== 5.9 Windows Vista highest score 6.0-6.9 many quad core processors will be able to score in the high 6 low 7 ranges 7.0+ many quad core processors will be able to score in the high 6 low 7 ranges 7.9 8-core systems will be able to approach 8.9 Windows 7 highest score Primary hard disk subscore (note) Score Conditions ======= ======================================== 1.9 Limit for pathological drives that stop responding when pending writes 2.0 Limit for pathological drives that stop responding when pending writes 2.9 Limit for pathological drives that stop responding when pending writes 3.0 Limit for pathological drives that stop responding when pending writes 5.9 highest you're likely to see without SSD Windows Vista highest score 7.9 Windows 7 highest score Bonus Chatter You can find your WEI detailed test results in: C:\Windows\Performance\WinSAT\DataStore e.g. 2011-11-06 01.00.19.482 Disk.Assessment (Recent).WinSAT.xml <WinSAT> <WinSPR> <DiskScore>5.9</DiskScore> </WinSPR> <Metrics> <DiskMetrics> <AvgThroughput units="MB/s" score="6.4" ioSize="65536" kind="Sequential Read">89.95188</AvgThroughput> <AvgThroughput units="MB/s" score="4.0" ioSize="16384" kind="Random Read">1.58000</AvgThroughput> <Responsiveness Reason="UnableToAssess" Kind="Cap">TRUE</Responsiveness> </DiskMetrics> </Metrics> </WinSAT> Pre-emptive snarky comment: "WEI is useless, it has no relation to reality" Fine, how do i increase my hard-drive's random I/O throughput?

  • Singleton pattern and broken double checked locking in real world java application

    - by saugata
    I was reading the article Double-checked locking and the Singleton pattern, on how double checked locking is broken, and some related questions here on stackoverflow. I have used this pattern/idiom several times without any issues. Since I have been using Java 5, my first thought was that this has been rectified in Java 5 memory model. However the article says This article refers to the Java Memory Model before it was revised for Java 5.0; statements about memory ordering may no longer be correct. However, the double-checked locking idiom is still broken under the new memory model. I'm wondering if anyone has actually run into this problem in any application and under what conditions.

  • HELP!!! Upgrading to windows 2008 R2 server has caused major issue with screen scraping remote serve

    - by bobsov534
    I have three servers. One is Windows 2003(A) and another is Windows 2008(B) and third one is also Windows 2008 (C). All of them are web servers. A and B contains classic asp pages and they are 32 bit servers and C contains asp.net pages and is 64 bit server. The asp pages of A and B use the screen scraping technology to render the asp.net pages from C. When A is ran, the asp.net page is rendered fine, meaning there are no broken images or file not found error. When B is ran, the images appears to be broken because its looking for those images in Server B instead of Server C itself. I believe this issue is caused by IIS 7 or 7.5 since IIS 6 has no problem scraping the remote server pages. Can you please help me with solution to this problem? This is sort of urgent since upgrading to windows server 2008 R2 now has been a major show stopper for us at the moment. Thanks in advance.

  • How to Manage project in this scenario

    - by vijay.shad
    Hi All, I am working on a web application which has got good amount of static or pre-login pages. These pages can have some simple forms as well where we would like to capture the visitor's details. Post login, I have got my main application. I am confused about the development and deployment architecture of my application. Post login part of my application has a release cycle of 1-2 months while pre-login pages are to be updated on a weekly basis. It is difficult to make a release of pre-login pages as the overall war also contains post-login application & which sometimes is not release ready. Currently, I have got both these parts bundled in the single war project. Please help me by letting me know the best practices whereby I can achieve following: Manage the releases of these two parts independently. I am using Maven. So is there a way I can share the resources, such as CSS, images etc between these two parts. Header and footer of my application is going to be same on pre-login & post-login pages. I was thinking of deploying these apps as two war files in my tomcat container. But then how will I manage the common resources like Css, images etc. Rgds Vijay

    I am struggling understanding what a clustered index in SQL Server 2005 is. I read the MSDN article Clustered Index Structures (among other things) but I am still unsure if I understand it correctly. The (main) question is: what happens if I insert a row (with a "low" key) into a table with a clustered index? The above mentioned MSDN article states: The pages in the data chain and the rows in them are ordered on the value of the clustered index key. And Using Clustered Indexes for example states: For example, if a record is added to the table that is close to the beginning of the sequentially ordered list, any records in the table after that record will need to shift to allow the record to be inserted. Does this mean that if I insert a row with a very "low" key into a table that already contains a gazillion rows literally all rows are physically shifted on disk? I cannot believe that. This would take ages, no? Or is it rather (as I suspect) that there are two scenarios depending on how "full" the first data page is. A) If the page has enough free space to accommodate the record it is placed into the existing data page and data might be (physically) reordered within that page. B) If the page does not have enough free space for the record a new data page would be created (anywhere on the disk!) and "linked" to the front of the leaf level of the B-Tree? This would then mean the "physical order" of the data is restricted to the "page level" (i.e. within a data page) but not to the pages residing on consecutive blocks on the physical hard drive. The data pages are then just linked together in the correct order. Or formulated in an alternative way: if SQL Server needs to read the first N rows of a table that has a clustered index it can read data pages sequentially (following the links) but these pages are not (necessarily) block wise in sequence on disk (so the disk head has to move "randomly"). How close am I? :)

  • how JVM arguments can be passed to apps started through java webstart in macOS.

    - by siva
    Hi, We have a application which is triggered from browser. This application consumes around 800 mb of memory. This works perfectly when invoked from any browsers in windows OS. The same application when triggered from MacOS throws an out of memory exception which occurs when the application is short of memory. Is there any way to increase the memory allocated for apps running in mac os environment. Also please let me know how JVM arguments can be passed to apps started through java webstart in macOS. Thanks in advance Regards, Siva

  • Tools to measure website size

    - by sexitrainer
    Can someone please recommend some tools that would help me measure the size of our website pages? I need to gather the size of the page rendered. We have over 100 pages and so obviously I am looking for a tool that could diagnose an entire domain or folder. I don't want to spend days measuring the pages one at a time. Thank you so much in advance. ac

  • MySQL configuration that allows for locking many tables?

    - by Floyd Bonne
    I need to do a MySQLDump on a DB with ~700 tables and when I try with my current configuration, I get an error: mysqldump: Got error: 1016: Can't open file: './my_db/content_node_field_instance.frm' (errno: 24) when using LOCK TABLES Searching around I've found that this happens because it tries to lock all tables and fails because they are "too many". I know I can try lock-tables=no and get a dump, but this way my DB might be in an inconsistent state. So, does anyone know what is the MySQL configuration setting I need to change in order to be able to do the locking I need? I'm running 5.1.37-1ubuntu5.1 with MyISAM. Thanks!

  • Automatically render changed partials in webby

    - by Tomas Sedovic
    I have a webby page and I'm have a layout that all my pages are rendered to. That layout uses a partial for navigation (in HAML): = render(:partial => "navigation", :locals => {:some => "stuff"} ) The problem is that when I change the _navigation partial, neither webby nor webby autobuild recognize the change and they don't re-render the pages. I've solved this by setting the dirty: true flag in the layout, but that makes all the pages re-render every time -- even when nothing changed. I know that this is not that big a deal, but still: is there a way so that when you change partial, webby recognizes this and renders only the affected pages (as it does with everything else)?
