• Scalability 101: How can I design a scalable web application using PHP?

  - by Legend

  I am building a web-application and have a couple of quick questions. From what I learnt, one should not worry about scalability when initially building the app and should only start worrying when the traffic increases. However, this being my first web-application, I am not quite sure if I should take an approach where I design things in an ad-hoc manner and later "fix" them. I have been reading stories about how people start off with an app that gets millions of users in a week or two. Not that I will face the same situation but I can't help but wonder, how do these people do it? Currently, I bought a shared hosting account on Lunarpages and that got me started in building and testing the application. However, I am interested in learning how to build the same application in a scalable-manner using the cloud, for instance, Amazon's EC2. From my understanding, I can see a couple of components: There is a load balancer that first receives requests and then decides where to route each request This request is then handled by a server replica that then processes the request and updates (if required) the database and sends back the response to the client If a similar request comes in, then a caching mechanism like memcached kicks into picture and returns objects from the cache A blackbox that handles database replication Specifically, I am trying to do the following: Setting up a load balancer (my homework revealed that HAProxy is one such load balancer) Setting up replication so that databases can be synchronized Using memcached Configuring Apache to work with multiple web servers Partitioning application to use Amazon EC2 and Amazon S3 (my application is something that will need great deal of storage) Finally, how can I avoid burning myself when using Amazon services? Because this is just a learning phase, I can probably do with 2-3 servers with a simple load balancer and replication but until I want to avoid paying loads of money accidentally. I am able to find resources on individual topics but am unable to find something that starts off from the big picture. Can someone please help me get started?

• Are we in demand?

  - by dotnetdev

  I was made redundant in the end of November. This wasn't because I lacked required skills (although I'm a youngster and in career levels a junior dev - though I knew a lot more than was called for in my job). Anyway, I was laid off due to the whole recession/credit crunch thing going on. I worked for a small company and money got tight and I had to go. I haven't made a thread about this but I have seen threads about others being laid off and experiencing a similar fate. This leads me to the question: What is the job market like for developers? Are we in demand? I ask this question on a global level, but I live in London UK (in case anyone comes across this thread from the same area). I am a .NET dev but my secondary skillset is Flex (actionscript too) and Java, which my personal portfolio is made with. I hope to be strong enough in this to do this commercially, with a few more months of practise. Then I will have more jobs applicable to me. Unfortunately, I use agencies and sites like Jobserve/Monster.com but no new jobs are ever posted on there so when you apply to all the relevant jobs, then what? Whatsmore, a lot of companies are putting a freeze on recruitment. Thanks

• Was Visual Studio 2008 or 2010 written to use multi cores?

  - by Erx_VB.NExT.Coder

  basically i want to know if the visual studio IDE and/or compiler in 2010 was written to make use of a multi core environment (i understand we can target multi core environments in 08 and 10, but that is not my question). i am trying to decide on if i should get a higher clock dual core or a lower clock quad core, as i want to try and figure out which processor will give me the absolute best possible experience with Visual Studio 2010 (ide and background compiler). if they are running the most important section (background compiler and other ide tasks) in one core, then the core will get cut off quicker if running a quad core, esp if background compiler is the heaviest task, i would imagine this would b e difficult to seperate in more then one process, so even if it uses multi cores you might still be better off with going for a higher clock cpu if the majority of the processing is still bound to occur in one core (ie the most significant part of the VS environment). i am a vb programmer, they've made great performance improvements in beta 2, congrats, but i would love to be able to use VS seamlessly... anyone have any ideas? thanks, erx

• how can i replace an image (inside a div) through jquery and ajax.

  - by oo

  I am trying to click on an image and change it to another image through jquery. When i step through the below code, on the serverside, the controller action fires and on the client side, i can see the correct html return in firebug watch window but the image doesn't change at all. any idea why this div is not updating? original div: <div class="inlineDiv" toggle="off" id="22"><img src="../../images/vote-favorite-off1.png" border="0"></div> jquery code: $(document).ready(function() { $('div.inlineDiv').live('click', function() { var id = $(this).attr("id"); var toggle = $(this).attr("toggle"); var url = '/Tracker/Update?id=' + id + '&toggle=' + toggle; $.get(url, function(data) { $(this).html(data); }); }); }); controller action: public ActionResult Update(int id, string toggle) { if (toggle == "off") { return Content("<img src='../../images/vote-favorite-on1.png' border=0'>"); } return Content("<img src='../../images/vote-favorite-off1.png' border=0'>"); }

• Concurrent Threads in C# using BackgroundWorker

  - by Jim Fell

  My C# application is such that a background worker is being used to wait for the acknowledgement of some transmitted data. Here is some psuedo code demonstrating what I'm trying to do: UI_thread { TransmitData() { // load data for tx // fire off TX background worker } RxSerialData() { // if received data is ack, set ack received flag } } TX_thread { // transmit data // set ack wait timeout // fire off ACK background worker // wait for ACK background worker to complete // evaluate status of ACK background worker as completed, failed, etc. } ACK_thread { // wait for ack received flag to be set } What happens is that the ACK BackgroundWorker times out, and the acknowledgement is never received. I'm fairly certain that it is being transmitted by the remote device because that device has not changed at all, and the C# application is transmitting. I have changed the ack thread from this (when it was working)... for( i = 0; (i < waitTimeoutVar) && (!bAckRxd); i++ ) { System.Threading.Thread.Sleep(1); } ...to this... DateTime dtThen = DateTime.Now(); DateTime dtNow; TimeSpan stTime; do { dtNow = DateTime.Now(); stTime = dtNow - dtThen; } while ( (stTime.TotalMilliseconds < waitTimeoutVar) && (!bAckRxd) ); The latter generates a very acurate wait time, as compared to the former. However, I am wondering if removal of the Sleep function is interferring with the ability to receive serial data. Does C# only allow one thread to run at a time, that is, do I have to put threads to sleep at some time to allow other threads to run? Any thoughts or suggestions you may have would be appreciated. I am using Microsoft Visual C# 2008 Express Edition. Thanks.

• Integrated Security on Reporting Services XML Datasource

  - by Nathan

  Hey all, I am working on setting up my report server to use a web service as an XML datasource. I seem to be having authentication issues between the web service and the report with I choose to use Integrated security. Here's what I have: 1) I have a website w/ an exposed service. This website is configured to run ONLY on Integrated Security. This means that we have all other modes turned off AND Enabled anonymous access turned off under directory security. 2) Within the Web.config of the website, I have the authentication mode set to Windows. 3) I have the report datasource set to being an XML data source. I have the correct URL to the service and have it set to Windows Integrated Security. Since I am making a hop from the Browser to the Reporting Server to the Web Service, I wonder if I am having an issue w/ Kerberos, but I am not sure. When I try to access the service, I get a 401 error. Here are the IIS logs that I am generating: 2011-01-07 14:52:12 W3SVC IP_ADDY POST /URL.asmx - 80 - IP_ADDY - 401 1 0 2011-01-07 14:52:12 W3SVC IP_ADDY POST /URL.asmx - 80 - IP_ADDY - 401 1 5 Has anyone worked out this issue before? Thanks!

• jQuery .die isnt killing an attached event?

  - by adam

  Hi I've just started experimenting with .live and .die and having some great results but one thing isn't working. I've been tinkering with firebugs console to try out my written code live to see if i can figure out the reason why .die isn't killing off an attached event. First if i do this //attach ajax submission $('a[href$=edit]').live("click", function(event) { $.get($(this).attr("href"), null, null); return false; }); Then as expected when I click on a link the ajax fires off and my server side code injects a form for inline editing. But sometimes I want to disable this behaviour and also make the link unclickable so I do the following //unbind ajax form creation when we click on a link, then disable its semantic behaviour $('a[href$=edit]').die("click").click( function(){ return false; } ); which works but if then try to remove this and restore that ajax goodness with the code below it doesn't work, Instead the link remains unclickable. I cant figure out why? Can anyone help? //remove any previous events from the links $('a[href$=edit]').die(); //attach ajax submission $('a[href$=edit]').live("click", function(event) { $.get($(this).attr("href"), null, null); return false; });

• Gtk: How can I get a part of a file in a textview with scrollbars relating to the full file

  - by badgerman1

  I'm trying to make a very large file editor (where the editor only stores a part of the buffer in memory at a time), but I'm stuck while building my textview object. Basically- I know that I have to be able to update the text view buffer dynamically, and I don't know hot to get the scrollbars to relate to the full file while the textview contains only a small buffer of the file. I've played with Gtk.Adjustment on a Gtk.ScrolledWindow and ScrollBars, but though I can extend the range of the scrollbars, they still apply to the range of the buffer and not the filesize (which I try to set via Gtk.Adjustment parameters) when I load into textview. I need to have a widget that "knows" that it is looking at a part of a file, and can load/unload buffers as necessary to view different parts of the file. So far, I believe I'll respond to the "change_view" to calculate when I'm off, or about to be off the current buffer and need to load the next, but I don't know how to get the scrollbars to have the top relate to the beginning of the file, and the bottom relate to the end of the file, rather than to the loaded buffer in textview. Any help would be greatly appreciated, thanks!

• How to remove the first and last character from a file using batch script?

  - by infant programmer

  This is my input file content which I am using to copy to the output file. #sdfs|dfasf|sdfs| sdfs|df!@$%%*&!sdffs| sasdfasfa|dfsdf|#sdfs| What I need to do is to omit the first character '#' and last character '|' in the output file. So the output will be, sdfs|dfasf|sdfs| sdfs|df!@$%%*&!sdffs| sasdfasfa|dfsdf|#sdfs Batch script is new to me, but I tried my best and tried these codes, :: drop first and last char @echo off > xyz.txt & setLocal EnableDelayedExpansion for /f "tokens=* delims=" %%a in (E:\abc1.txt) do ( set str=%%a set str=!str:~1! echo !str!>> xyz.txt ) and @echo off > xyz.txt setLocal EnableDelayedExpansion for /f "tokens=1,2 delims= " %%a in (E:\abc1.txt) do ( set /a N+=1 if !N! gtr 2 ( echo %%a >> xyz.txt ) else ( set str=%%a set str=!str:#=! echo !str! >> xyz.txt ) ) As you can see they are not able to produce the required output.

• How to "upgrade" the database in real world?

  - by Tattat

  My company have develop a web application using php + mysql. The system can display a product's original price and discount price to the user. If you haven't logined, you get the original price, if you loginned , you get the discount price. It is pretty easy to understand. But my company want more features in the system, it want to display different prices base on different user. For example, user A is a golden parnter, he can get 50% off. User B is a silver parnter, only have 30 % off. But this logic is not prepare in the original system, so I need to add some attribute in the database, at least a user type in this example. Is there any recommendation on how to merge current database to my new version of database. Also, all the data should preserver, and the server should works 24/7. (within stop the database) Is it possible to do so? Also , any recommend for future maintaince advice? Thz u.

• I want to add and remove items from a menu with PHP.

  - by CDeanMartin

  This menu will need to be updated daily. <html><head></head><body> <h1> Welcome to Burgerama </h1> <?php include("menuBuilder.php"); showBurgerMenu(); ?> </body></html> Menu items are stored in the database. Items have a display field; if it is on, the item should be displayed on the menu. The menu only displays 4 or 5 "specials" at a time, and the manager needs to change menu items easily. I want to make a menu editing page like this: <?php include("burger_queries.php"); dbconnect("burger_database"); foreach($menuItem in burger_database) { echo createToggleButton($menuItem); } ?> .. with a toggle button for each menu item. Ideally the button will be labeled with the menu item, in blue if the item is "on", and red if the item is "off." Clicking the button switches between "on" and "off" I am stuck trying to a get a button to execute an UPDATE query on its corresponding menu item.

• Center container horizontally and vertically

  - by Joey

  Looking over other question on this site, I used a method of setting all the positions to 0 with auto margins, but this has some unwanted behavior. If you resize the window vertically, the top of the container moves off of the top of the page. It needs to stop when it hits the top. JSFIDDLE: http://jsfiddle.net/jd67ca5y/ HTML: <div id="container"> <p>This is the container.</p> <p>If you resize the JSFiddle window horizontally, you will see that the left edge of the box doesn't move past the left edge of the window. This is correct behaviour.</p> <p>Now if you move the window vertically, the top of this container will disappear off of the top of the window. This is wrong.</p> </div> CSS: #container { margin:auto; height:300px; width:300px; top:0; bottom:0; left:0; right:0; position:absolute; border:1px solid; padding:10px; }

• IntelliJ inspection -- non-thrown exception

  - by skiaddict1

  This is a follow-up question to 1832203. I'm making it a new question as well, because it seems that posting an answer to a question doesn't change its position on the java page and so I'm worried that it won't get seen. Apologies if I've just stepped on some etiquette toes. I'm an IntelliJ newbie -- started using it two days ago and I'm absolutely head-over-heels in love! One of the things I adore is the code inspections. However... In one of my classes I often create exceptions without throwing them. If I can't turn off (or downgrade) the inspection warning for this then I can see I'm going to end up ignoring inspections on at least that file (if not the entire project), which would be a real pity. I've done a search in the inspection settings for "exception", and found nothing that relates exactly, so I turned them all off just to see, and it's still doing it (even after a rebuild...BTW when are inspections redone? at save? at rebuild? ???), so I would really like some help on how to make this one into an info/typo level -- which I can then ignore. Using the free version, if that makes any difference TIA to all those experienced IntelliJ warriors out there!

• mod_rewrite: no access to real files and directories

  - by tshabalala

  Hello. I use mod_rewrite/.htaccess for pretty URLs. I forward all the requests to my index.php, like this: RewriteRule ^/?([a-zA-Z0-9/-]+)/?$ /index.php [NC,L] The index.php then handles the requests. I'm also using this condition/rule to eliminate trailing slashes (or rather rewrite them to the URL without a trailing slash, with a 301 redirect; I'm doing this to avoid duplicate content and because I like no trailing slashes better): RewriteCond %{HTTP_HOST} !^\.localhost$ [NC] RewriteRule ^(.+)/$ http://%{HTTP_HOST}/$1 [R=301,L] This works well, except that I now get an infinite loop when trying to access a (real) directory (the rewrite rule removes the trailing slash, the server adds it again, ...). I solved this by setting the DirectorySlash directive to Off: DirectorySlash Off I don't know how good this solution is, I don't feel too confident about it tbh. Anyway, what I'd like to do is completely ignore "real" files and directories, since I don't need them and I only use pretty URLs with "virtual" files/directories anyway. This would allow me to avoid the DirectorySlash workaround/hack too. Is this possible? Thanks!

• And now for a complete change of direction from C++ function pointers

  - by David

  I am building a part of a simulator. We are building off of a legacy simulator, but going in different direction, incorporating live bits along side of the simulated bits. The piece I am working on has to, effectively route commands from the central controller to the various bits. In the legacy code, there is a const array populated with an enumerated type. A command comes in, it is looked up in the table, then shipped off to a switch statement keyed by the enumerated type. The type enumeration has a choice VALID_BUT_NOT_SIMULATED, which is effectively a no-op from the point of the sim. I need to turn those no-ops into commands to actual other things [new simulated bits| live bits]. The new stuff and the live stuff have different interfaces than the old stuff [which makes me laugh about the shill job that it took to make it all happen, but that is a topic for a different discussion]. I like the array because it is a very apt description of the live thing this chunk is simulating [latching circuits by row and column]. I thought that I would try to replace the enumerated types in the array with pointers to functions and call them directly. This would be in lieu of the lookup+switch.

• How do I obtain selected rows in a DataGridView from different pages

  - by cmrhema

  Hi, I have a windows forms DataGridView, where I have data and a checkbox for each row. I will select check box for a particular row and all the selected rows will be populated in another page. if (grdEmp.Rows.Count > 0) { var selectedEmpIDs= from DataGridViewRow coll in grdEmp.Rows where Convert.ToBoolean(coll.Cells["Select"].Value) == true select coll; if (selectedEmpIDs.Count() > 0) { foreach (DataGridViewRow row in selectedEmpIDs) { selectedEmp+= row.Cells["EmpId"].Value + ","; } } } This works good only for one page. When I navigate to another page, and click the selected rows, the previous one goes off. How do I resolve it. Thanks cmrhema Note :Sorry for the confusion, When I meant it works good for a page, I meant paging. I think I need to add more inputs, There are 10 pages in the gridview. I select the first record from each page of the gridview, one after another by clicking next page( Page next button). But only the record that was selected the last is getting displayed and others and ignored off. What could be the prblm

• Nginx - Treats PHP as binary

  - by Think Floyd

  We are running Nginx+FastCgi as the backend for our Drupal site. Everything seems to work like fine, except for this one url. http:///sites/all/modules/tinymce/tinymce/jscripts/tiny_mce/plugins/smimage/index.php (We use TinyMCE module in Drupal, and the url above is invoked when user tries to upload an image) When we were using Apache, everything was working fine. However, nginx treats that above url Binary and tries to Download it. (We've verified that the file pointed out by the url is a valid PHP file) Any idea what could be wrong here? I think it's something to do with the NGINX configuration, but not entirely sure what that is. Any help is greatly appreciated. Config: Here's the snippet from the nginx configuration file: root /var/www/; index index.php; if (!-e $request_filename) { rewrite ^/(.*)$ /index.php?q=$1 last; } error_page 404 index.php; location ~* \.(engine|inc|info|install|module|profile|po|sh|.*sql|theme|tpl(\.php)?|xtmpl)$|^(code-style\.pl|Entries.*|Repository|Root|Tag|Template)$ { deny all; } location ~* ^.+\.(jpg|jpeg|gif|png|ico)$ { access_log off; expires 7d; } location ~* ^.+\.(css|js)$ { access_log off; expires 7d; } location ~ .php$ { include /etc/nginx/fcgi.conf; fastcgi_pass 127.0.0.1:8888; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; } location ~ /\.ht { deny all; }

• Object model design choice

  - by spinon

  I am currently working on a ASP.NET MVC reporting application using C#. This is a redesign from a PHP application that was just initially thrown together and is now starting to gain some more traction. SowWe are in the process of reworking the backend to have a more OO approach. One of the descisions I am currently wrestling with is how to structure the domain objects. Since 95% of the site is readonly I am not sure if the typical approaches are practical. Should I create domain objects for the primary pieces of the application (ticket, assignment, assignee) and then create static methods off of these areas to pull the reporting data? Or should I just skip that part and create the chart data classes and have some get method off of these classes? It's not a real big application and currenlty I am the only one developing on it. But I feel torn as to which approach. I feel that the first one is the better choice but maybe overkill given that the majority of uses is for aggregate reporting. Anybody have some good insight on why I should go one way or another?

• Search Box/Transition won't work in Firefox

  - by user2522488

  I disabled the search box on IE, because IE kept centering it over the navigation. It works in Chrome, I'm not sure about opera (and I'm not sure if I care) but it won't work in Firefox. The ease-out timing works in Firefox, but nothing else really works. I've tried other things to work around the issue, but every time I try something different, the search box's positioning gets thrown off. If you look at it in Firefox, it looks fine-- until you click on it to search. http://kissoff.weebly.com/ You can see what the search box is supposed to do if you look at it and click on it in Chrome. I'm sure the positioning is off, I'm not sure (I'm new to css). Any help is appreciated. #search {} #search input[type="text"] { background: url(search-white.png) no-repeat 10px 6px #fcfcfc; border: 1px solid #d1d1d1; position: fixed; margin-left: 350px; margin-right: 0px; margin-top: 0px; color: #bebebe; width: 150px; padding: 6px 15px 6px 35px; -webkit-border-radius: 20px; -moz-border-radius: 20px; border-radius: 20px; text-shadow: 0 2px 3px rgba(0, 0, 0, 0.1); -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -webkit-transition: all 0.7s ease 0s; -moz-transition: all 0.7s ease 0s; -o-transition: all 0.7s ease 0s; transition: all 0.7s ease 0s; float: right; } #search input[type="text"]:focus { width: 200px; }

• Running a process at the Windows 7 Welcome Screen

  - by peelman

  So here's the scoop: I wrote a tiny C# app a while back that displays the hostname, ip address, imaged date, thaw status (we use DeepFreeze), current domain, and the current date/time, to display on the welcome screen of our Windows 7 lab machines. This was to replace our previous information block, which was set statically at startup and actually embedded text into the background, with something a little more dynamic and functional. The app uses a Timer to update the ip address, deepfreeze status, and clock every second, and it checks to see if a user has logged in and kills itself when it detects such a condition. If we just run it, via our startup script (set via group policy), it holds the script open and the machine never makes it to the login prompt. If we use something like the start or cmd commands to start it off under a separate shell/process, it runs until the startup script finishes, at which point Windows seems to clean up any and all child processes of the script. We're currently able to bypass that using psexec -s -d -i -x to fire it off, which lets it persist after the startup script is completed, but can be incredibly slow, adding anywhere between 5 seconds and over a minute to our startup time. We have experimented with using another C# app to start the process, via the Process class, using WMI Calls (Win32_Process and Win32_ProcessStartup) with various startup flags, etc, but all end with the same result of the script finishing and the info block process getting killed. I tinkered with rewriting the app as a service, but services were never designed to interact with the desktop, let alone the login window, and getting things operating in the right context never really seemed to work out. So for the question: Does anybody have a good way to accomplish this? Launch a task so that it would be independent of the startup script and run on top of the welcome screen?

• What is the fastest way to insert 100 000 records from one database to another?

  - by Pentium10

  I have a mobile application. My client has a large data set ~100.000 records. It's updated frequently. When we sync we need to copy from one database to another. I have attached the second database to the main, and run an insert into table select * from sync.table. This is extremely slow, it takes about 10 minutes I think. I noticed that the journal file gets increased step by step. How can I speed this up? EDITED 1 I have indexes off, and I have journal off. Using insert into table select * from sync.table it still takes 10 minutes. EDITED 2 If I run a query like select id,invitem,invid,cost from inventory where itemtype = 1 order by invitem limit 50 it takes 15-20 seconds. The table schema is: CREATE TABLE inventory ('id' INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, 'serverid' INTEGER NOT NULL DEFAULT 0, 'itemtype' INTEGER NOT NULL DEFAULT 0, 'invitem' VARCHAR, 'instock' FLOAT NOT NULL DEFAULT 0, 'cost' FLOAT NOT NULL DEFAULT 0, 'invid' VARCHAR, 'categoryid' INTEGER DEFAULT 0, 'pdacategoryid' INTEGER DEFAULT 0, 'notes' VARCHAR, 'threshold' INTEGER NOT NULL DEFAULT 0, 'ordered' INTEGER NOT NULL DEFAULT 0, 'supplier' VARCHAR, 'markup' FLOAT NOT NULL DEFAULT 0, 'taxfree' INTEGER NOT NULL DEFAULT 0, 'dirty' INTEGER NOT NULL DEFAULT 1, 'username' VARCHAR, 'version' INTEGER NOT NULL DEFAULT 15 ) Indexes are created like CREATE INDEX idx_inventory_categoryid ON inventory (pdacategoryid); CREATE INDEX idx_inventory_invitem ON inventory (invitem); CREATE INDEX idx_inventory_itemtype ON inventory (itemtype); I am wondering, the insert into ... select * from isn't the fastest built-in way to do massive data copy? EDITED 3 SQLite is serverless, so please stop voting a particular answer, because that is not the answer I'm sure.

• How to explain to client that you can't give them some of the source

  - by Bo

  We have a number of AS/Flex components that we've built over time and improved upon. They've been turned into components so they can be reused in different projects and save us time. So you can think of them as part of an in-house framework of sorts. We're now realizing that it doesn't make sense to release the source code for these components to the various clients as part of the project, because technically this code isn't really owned by the clients. So my question When a client comes to you, how do you explain to them that you can't give them the full source code for those components. The client doesn't understand the difference, he just expects you to give them all the code for the site that he paid you to do. He doesn't understand that this code has taken you a lot longer to write than what he's paying for his site. But since he doesn't understand, he would get turned off and thinks you're ripping him off or something. How do you handle this situation? What do you tell clients upfront? Do you advertise it on your site from the very beginning? How do you handle their objections so they still hire you? As a side question, how often do you give AS and Flex source code to your clients? In the case when the code doesn't have any in-house components that you reuse in several projects, and in the case when it does have in-house components.
