• What is considered a long execution time?

  - by stjowa

  I am trying to figure out just how "efficient" my server-side code is. Using start and end microtime(true) values, I am able to calculate the time it took my script to run. I am getting times from .3 - .5 seconds. These scripts do a number of database queries to return different values to the user. What is considered an efficient execution time for PHP scripts that will be run online for a website? Note: I know it depends on exactly what is being done, but just consider this a standard script that reads from a database and returns values to the user. Also, I look at Google and see them search the internet in .15 seconds and I feel like my script is crap. Thanks.

• Can someone suggest a way to learn regex?

  - by Nick Brooks

  In my situation knowing Regex would be very useful but I can't seem to be able to learn it. I completely don't understand it and I find it quite strange. To me Regex is just a set of jumbled up symbols which 'somehow' does the job. I looked at many tutorials and still haven't figured how to use it. The other thing I find weird that whenever I search for a way to implement something with regex I find lots of different solutions. For example these are for 'matching text between the brackets' 1: \((.*?)\) 2: ((.+?)) That confuses me even more ... Can someone suggest a good way of learning it? Personally I find it even more difficult than assembly language. For now I'm avoiding Regex and using things such as "substr" to get the bits I need.

• Disabling scoring in Lucene(.NET)

  - by user72185

  Hi, When searching, is there a way to disable scoring for any query? The scenario is that the user refines his query by trying different combinations of words, phrases etc., and needs realtime (well, reasonably fast at least) responses on the number of hits. Search time slows down a lot when there are millions of hits due to scoring, but the user really doesn't care about all these documents. As soon as he sees there are 1M+ hits he will start adding additional words to the query. A "Sort by relevance" option would allow him to do this quickly, while turning scoring back on when the number of hits is reasonable. Is this possible? I'm using Lucene.NET 2.9.2 but AFAIK it is identical to the Java version.

• Google's Geocoder returns wrong country

  - by 6bytes

  Hi I'm using Google's Geocoder to find lat lng coordinates for a given address. var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': address, 'region': 'uk' }, function(results, status) { if(status == google.maps.GeocoderStatus.OK) { lat: results[0].geometry.location.lat(), lng: results[0].geometry.location.lng() }); address variable is taken from an input field. I want to search locations only in UK. I thought that specifying 'region': 'uk' should be enough but it's not. When I type in "Boston" it founds Boston in US and I wanted the one in UK. How to restrict Geocoder to return locations only from one country or maybe from a certain lat lng range? Thanks

• problem with Chrome form handling: input onfocus="this.select()"

  - by binaryorganic

  I'm using the following HTML code to autoselect some text in a form field when a user clicks on the field: input onfocus="this.select()" type="text" value="Search" This works fine in Firefox and Internet Explorer (the purpose being to use the default text to describe the field to the user, but highlight it so that on click they can just start typing), but I'm having trouble getting it to work in Chrome. When I click the form field in Chrome the text is highlighted for just a split second and then the cursor jumps to the end of the default text and the highlighting goes away. Any ideas on how to get this working in Chrome as well?

• What event do I need to supress to stop IE from "Dinging" when I press enter in a text box?

  - by scunliffe

  On simple forms with one text box pressing enter submits the form (and this is great for easy search forms) However on a form with multiple fields, pressing Enter in an input="text" box won't do anything (e.g. submit) but in IE it "Dings" as if you have tried to delete an undeletable object. The question is... what event do I need to suppress in IE to stop this sound? e.g. if I have a username/password form, I DO want the enter key to submit the form, but I certainly don't want the "error" sound. Example site with the sound: http://www.sears.com/shc/s/StoreLocatorView?storeId=10153&catalogId=12605 Just press Enter in any of the text fields. Ding!, Ding!, Ding! Non-IE users, the sound is the: Program Events Windows Default Beep ("Windows XP Ding.wav")

• maximum execution time for javascript

  - by Andrew Chang

  I know both ie and firefox have limits for javascript execution here: hxxp://support.microsoft.com/?kbid=175500 Based on number of statements executed, I heard it was 5 million somewhere in ie hxxp://webcache.googleusercontent.com/search?q=cache:_iKHhdfpN-MJ:kb.mozillazine.org/Dom.max_script_run_time+dom.max_script_run_time&hl=en&gl=ca&strip=1 (google cache since site takes forever to load for me) based on number of seconds in firefox, it's 10 seconds by default for my version The thing I don't get is what cases will go over these limits: I'm sure a giant loop will go over the limit for execution time But will an event hander go over the limit, if itself it's execution time is under the limit but if it occurs multiple times? Example: Lets say I have a timer on my page, that executes some javascript every 20 seconds. The execution time for the timer handler is 1 second. Does firefox and ie treat each call of the timer function seperatly, so it never goes over the limit, or is it that firefox/ie adds up the time of each call so after the handler finishes, so after 200 seconds on my site (with the timer called 10 times) an error occurs even though the timer handler itself is only 1 second long?

• ZipArchive php Class - Does it support all servers?

  - by SoLoGHoST

  Ok, just wondering on the versions of PHP that this class is built into. And if they are built into all platforms (OS's). I'm wanting an approach to search through a zip file and place files using file_put_contents in different filepaths within the webroot. In any case, I'm familiar with how to do this with the ZipArchive class, but I'm wondering if using this class would be a good solution and support MOST, if not ALL servers?? I mean, I'd rather not use a method that requires the Server to have it installed. I'm looking for a solution to this that will support at least MOST servers without having to install the class... Thanks :) Also, I'd like to support opening tar.gz and/or .tgz files if possible, but I don't think the ZipArchive class supports this, but perhaps a different built-in php class does??

• How to create an eclipse plug-in?

  - by Amir Rachum

  I've decided that as a pet project meant for learning, I would create a new Eclipse plug-in that, for a given class, takes all private member names and adds a prefix to their name (it doesn't matter to me if it can already be done or not, this is meant to be a learning experience). I have never developed an Eclipse plug-in and I'm not sure where to begin. Do I need to install some application for this development? How does it work? Where do I begin? I did a Google search but all the tutorials and results I found were old and referred to antiquated versions of Eclipse, so I'm not sure if they're still accurate.

• Python - urllib2 & cookielib

• SAP .NET Connector

  - by mehmet6parmak

  Hi all, I need to connect to SAP and do a simple update but it will be the first time for me connecting to SAP and i know almost nothing. After some search on web i learned that there is an API which works only in visual studio 2003 (SAP .NET Connector). But i have a win7 .net 3.5 sp1 system. Is there any free way to connect to SAP using visual studio 2008 on the system above? (Free means without additional payment, we have an SAP account) Thanks...

• What is better, a STL list or a STL Map for 20 entries, considering order of insertion is as importa

  - by Abhijeet

  I have the following scenario.The implementation is required for a real time application. 1)I need to store at max 20 entries in a container(STL Map, STL List etc). 2)If a new entry comes and 20 entries are already present i have to overwrite the oldest entry with the new entry. Considering point 2, i feel if the container is full (Max 20 entries) 'list' is the best bet as i can always remove the first entry in the list and add the new one at last (push_back). However, search won't be as efficient. For only 20 entries, does it really make a big difference in terms of searching efficiency if i use a list in place of a map? Also considering the cost of insertion in map i feel i should go for a list? Could you please tell what is a better bet for me ?

• WiX ServiceDependency for dynamically named services

  - by glenneroo

  The target system will have a set of dynamically-named CORBA services installed that my own service is dependent on e.g. IT iona_services.config_rep.VirtualXP-37192 cfr-DOMAIN IT iona_services.event.VirtualXP-37192 DOMAIN IT iona_services.ifr.VirtualXP-37192 DOMAIN IT iona_services.locator.VirtualXP-37192 DOMAIN IT iona_services.naming.VirtualXP-37192 DOMAIN IT iona_services.node_daemon.VirtualXP-37192 DOMAIN where "VirtualXP-37192" is the name of the PC. Any ideas what i have to put into this line: <ServiceDependency Id="IT iona_services.*" Group="yes" /> Will i need a custom action thingy to retrieve a list of installed services and search through those? Or is there a way in WiX to retrieve a list of services?

• Extracting a string starting with x and ending with y

  - by DMan

  First of all, I did a search on this and was able to find how to use something like String.Split() to extract the string based on a condition. I wasn't able to find however, how to extract it based on an ending condition as well. For example, I have a file with links to images: http://i594.photobucket.com/albums/tt27/34/444.jpghttp://i594.photobucket.com/albums/as/asfd/ghjk6.jpg You will notice that all the images start with http:// and end with .jpg. However, .jpg is succeeded by http:// without a space, making this a little more difficult. So basically I'm trying to find a way (Regex?) to extract a string from a string that starts with http:// and ends with .jpg

• How To: Referencing LAPACK library from FORTRAN 95 in Cygwin

  - by cholmgreen

  I have a FORTRAN 95 program that needs to make some calls to the LAPACK library. I recently found out that Cygwin because it can install LAPACK as an extra option. Well, LAPACK exists in the /lib/lapack/ directory as "cyglapack.dll". Having only a very informal training in Fortran programming, I have no idea how to reference a .dll library as opposed to a .mod module. Any suggestions or directions to articles answering my question are GREATLY appreciated! (P.S. I did search first.. I don't think I know the proper terms to get a useful article.)

• Entity Framework Performance Inconsistency Compared to Sql Management Studio

  - by AndyV

  I'm getting timeouts with a very basic EF statement. I'm simply doing a select from a single table with a Entity.Title.StartsWith("test") and a .Take(25). When I run this for a search that returns no results I get a timeout. If I profile and grab the sql statement it looks fine, and if I run that sql in Management Studio it runs in a fraction of a second! Why would the same query run sub-second in Management Studio and timeout when generated by EF and called from an Asp.Net app?

• Android:Where is exactly Android 1.6 SDK download?

  - by user187532

  Hello friends, I want install Android version 1.6 SDK. I already have Android development setup with Eclipse and Android 1.5 SDK. Wherever i search in Google to download Android 1.6 SDK, it finally goes to link: http://developer.android.com/intl/zh-CN/sdk/index.html This link has three setup SDK zip files, but no where mentioned what version of SDK setup are those? Why such confusions in this Android website for showing just version of SDK setup files? Where i can get exactly Android 1.6 SDK setup download? Could someone point out me clearly? Is there any special steps that i need to follow to overwrite 1.6 SDK with my existing setup environment? Thank you.

• Integrating GSL onto iPhone Xcode

  - by zeroinverse

  I have been trying to integrate GSL (Gnu Scientific Library) into an iPhone project using Xcode. The challenge is GSL has all the modules in different folders, yet when their header files are reference, they often reference instead of or . At least with I could use Xcode's recursive header file search to find it. But with , basically file not found. Does anyone have an easy way to address the hierarchical GSL structure to compile into Xcode? I can do it the tedious way of fixing all the #INCLUDE lines but hoping there is a better alternative. This way, I can more easily update GSL when changes are made by the community. NOTE: I found Xcode needs to find the right header file locations (make sure to adjust your TARGET Build settings, not just your Project Build settings).

• Why is there so much "magic" in Perl?

  - by eugene y

  I'm looking through perlop and perlsub pages of the Perl manual. There are many references about "magic" and "magical" here (just search any of them for the "magic"). I wonder why is Perl so rich in them. Some examples: print ++($foo = 'zz') # prints 'aaa' printf "%d: %s", $! = 1, $! # prints '1: Operation not permitted' use warnings; my $i; print $i++ # no warning for uninitialized value while (my $line = <FH>) { ... } # $line is actually tested for definedness

• Gmail freezes on display:none

  - by kambamsu

  Hi, I have a "div" which i insert in everypage, inside which resides my plugin. In certain pages where i might not need to use the plugin, i do a display:none on the div. This seems to work perfectly fine in all browsers. The only exception to this seems to be the "google.com" pages. Whether it be the search page or the gmail page, it seems to freeze once i do this display:none. By freeze i mean that none of the links are clickable after this. Is there something specific with these pages that i'm missing?? Any help would be appreciated. Thanks

• Can't get to Pex download (or visual studio 2010)

  - by Vaccano

  I know this is probably not a "True" stackoverflow question, but here it is anyway: Is anyone able to get to the MSDN Download of Visual Studio 2010? I just get "Your search did not match any products." when I click on the New Downloads-Visual Studio 2010 link. I was able to download Visual Studio on Monday. But it is gone now. That is not really my issue though. That page is also where the pex download is. With that page down I can't download pex either. (I checked with a co-worker (who is having the same issue) before posting. So I know it is not just me.)

• Stop loading detail grid at page load.

  How can I stop DetailGrid from not loading at page load. Because I have button in master grid to load Detail Grid. Below is code for Detail Grid. jQuery().ready(function () { jQuery("#list10_d").jqGrid({ height: 100, url: '/JQSandbox/MyFullSubGridData?id=0', datatype: "json", mtype: 'POST', colNames: ['Index', 'Name', 'Department', 'Hire Date', 'Supervisor'], colModel: [ { name: 'employeeID', index: 'employeeID', width: 10 }, { width: 30 }, { name: 'employeeDepartment', index: 'employeeDepartment', width: 30 }, { name: 'employeeHiredate', index: 'employeeHiredate', width: 40, sortable: false }, { name: 'employeeSup', index: 'employeeSup', formatter: 'checkbox', align: 'center', width: 30, search: false } ], loadtext: "", loadui: "block", width: 500, rowNum: 5, rowList: [5, 10, 20], pager: '#pager10_d', sortname: 'employeeID', viewrecords: true, sortorder: "asc", multiselect: true, caption: "Detail Grid: 1" }).navGrid('#pager10_d', { add: false, edit: false, del: false }); });
