• What Kind of Knowledge is Necessary For a Permon Who Does Not Have IT Background? [closed]

  - by skyflyer

  One of my colleagues joined our company, which by the way is a internet company, months ago as an on-line marketing specialist. He majored English in his college and has never deeply touched IT before. He says that to be a good on-line marketing specialist he needs to lean some basic IT skills in order to deliver superb work. According to him, things like Search Engine Optimization, monitoring competitors' web sites, design some functionality on web site and so on require IT entree-level knowledge. And he asks me what kind knowledge is helpful for him to do his job. I am stunted by his question. It is easy enough to answer, things like HTML, CSS, even Photo-shop are required in some job descriptions. Also, I believe some basic understanding of dynamic web site, static web site is helpful to him. On the other hand, as a techie I still feel my answer is awkward. What is your opinion on this? Always lot of thanks to you guys on SO.

• Better product to develop for, iPad or Android based tablet in a purely business related application

  - by Caylem

  Hey guys Just wondering what you'd suggest as the best platform for developing a business application for a tablet device. The application needs to be multitouch, have access to a maps API, a database on the device. It will not be going on sale in the app store or Androids market, it is purely for specific business task and not for the general consumer. Obviously the options seem to be iPhone OS and the iPad or Android and an Android tablet device. The form factor for the end product requires something in the region of 8 inch+ screen and enough processing power to provide a good experience for the end user. Any help would be much appreciated. Thanks

• Launching an activity at its current state.

  - by Profete162

  Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

• Choosing a Portal / CMS software for developing multi brand websites?

  - by hbagchi

  We are in the early stage of overhauling a multi-brand website built using a custom developed java mvc framework to enable web 2.0 features. Built-in features we are looking at are: i18n, sso, content search and indexing, personalization, mashup support, ajax support, rich media content storage and management support, friendly to search engine optimizations, bookmarkable URLs, support for social networking sites, support for page composition and decoration using templates. A combination of these features are supported by many portal and cms software. Any insights will be very helpful in using a portal/cms combination to address this requirements! This is a follow-up on this post focusing on the portal/cms angle

  - by Ibrahim Azhar Armar

  hi, i am building a real estate application where in it will store the properties and search it. the property will have different categories like (residential, commercial, industrial or agricultural). based upon the category i want to serailize each and every property listing . for example the property with id 1 belongs to resedential will have the serial code rs_SOMERANDOMUNIQUENUMBER. and for commercial it can be cm_SOMERANDOMUNIQUENUMBER and so on. for this my database table looks like this. CREATE TABLE IF NOT EXISTS `propSerials` ( `id` bigint(20) NOT NULL auto_increment, `serial` varchar(50) NOT NULL, `property_id` int(10) UNIQUE NOT NULL, PRIMARY KEY  (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; what would be the best possible format to store the serial with the prefix according to category? thank you

• Mobile Application Upgrade/Update Framework

  - by sharjeel

  I am developing a few mobile apps for different platforms including Blackberry, Windows Mobile, Android and Symbian S60. I want my mobile apps to have the capability of checking for updates before starting and in case a new version is available, prompt the user to upgrade. Moreover in certain cases (like security patches), the user must be forced to update or the app won't work. Surely I can cook some code to achieve the task but I was wondering if there are already existing framework to serve the purpose so that I don't have to re-invent the wheel and test all over?

• Does the number of busy worker threads in the CLR ThreadPool affect performance of I/O threads?

  - by andrej351

  We have a Windows Service which hosts a number of WCF services and, in an unrelated part of the app, makes extensive use of the TPL Task class to asynchronously do relatively short bits of work. It is my understanding that WCF uses managed I/O threads from the ThreadPool to execute requests. I noticed that after deploying a feature which significantly raised the applications use of Tasks, and as such the use of ThreadPool worker threads as well, performance of a couple of web services has become very slow. We're talking minutes instead of less than a second. The number of Tasks actually trying to run at any one time can range between 20 and 1000, which makes me think that any new (last in) work needing some CPU time could be forced to wait for quite some time. Does the (in my case extremely large) number of busy ThreadPool worker threads affect the ThreadPool's managed I/O threads? Or could these two be connected in any way? Thanks!

• How to automatically run in the background?

  - by Hun1Ahpu

  I'm not sure that it's not implemented yet, I hope that it is. But I know that in .Net programmers should manually run time-consuming task in the background thread. So every time we handle some UI event and we understand that this will take some time we also understand that this will hang UI thread and our application. And then we make all this Background work things and handle callbacks or whatever. So my question is: Is there in some language/platform a mechanism that will automatically run time-consuming tasks in the background and will do all related work itself? So we just write the code for handling specific UI event and this code will be somehow detected as time-consuming and will be executed in background. And if there isn't, then why?

• What to read as a good intro and quickstart to aspect-oriented programming and metaprogramming?

  - by Ivan

  As I've found myself repeating myself a lot, writing very similar queries and classes for different entities (despite of doing strong object and relational normalisation), etc, I've came to an Idea that I could and should automate the most of this and write an engine which will compile simple declarative models I specify into all the code limiting my job to describe the task and and finally just customise the result as needed. As far as I know this is about metaprogramming and aspect-oriented programming. How do I get acquainted with modern tools available quickly so that I don't invent one more bicycle developing my own?

• Is there any performance overhead in using RaiseEvent in .net

  - by Sachin

  Is there any performance overhead in using RaiseEvent in .net I have a code which is similar to following. Dim _startTick As Integer = Environment.TickCount 'Do some Task' Dim duration As Integer = Environment.TickCount - _startTick Logger.Debug("Time taken : {0}", duration) RaiseEvent Datareceived() Above code returns Time Taken :1200 Time Taken :1400 But if remove RaiseEvent it returns Time Taken :110 Time Taken :121 I am surprised that the raiseevent is called after the logging of time taken. How it effects total time taken. I am working on Compact framework. Update: In the Eventhandler I had given a MsgBox. When I removed the message box it is now showing time taken as 110,121,etc i.e. less that 500 milliseconds. If I put the Msgbox back in eventhandler it shows 1200,1400,etc i.e. more that a second. More surprised now.(Event is raised after the logging part)

• Pro's and Con's of unit testing after the fact.

  - by scope-creep

  I have a largish complex app around 27k lines. Its essentially a rule drive multithreaded processing engine, without giving too much away Its been partially tested as it's been built, certain components. Question I have, is what is the pro's and con's of doing unit testing on after the fact, so to speak, after its been implemented. It is clear that traditional testing is going to take 2-3+ months to test every facet, and it all needs to work, and that time is not available really. I've done a fair bit of unit testing in the past, but generally it's been on desktop automation or LOB apps, which are fairly simple. The app is itself is highly componentized internally, interface driven really. I've not decided on what particular framework to use. Any advice would be appreciated. What say you.

• Given two lines on a plane, how to find integer points closest to their interseciton?

  - by Lukasz Lew

  I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach.

• Optimizing MySQL statement with lot of count(row) an sum(row+row2)...

  - by Zombies

  I need to use InnoDB storage engine on a table with about 1mil or so records in it at any given time. It has records being inserted to it at a very fast rate, which are then dropped within a few days, maybe a week. The ping table has about a million rows, whereas the website table only about 10,000. My statement is this: select url from website ws, ping pi where ws.idproxy = pi.idproxy and pi.entrytime > curdate() - 3 and contentping+tcpping is not null group by url having sum(contentping+tcpping)/(count(*)-count(errortype)) < 500 and count(*) > 3 and count(errortype)/count(*) < .15 order by sum(contentping+tcpping)/(count(*)-count(errortype)) asc; I added an index on entrytime, yet no dice. Can anyone throw me a bone as to what I should consider to look into for basic optimization of this query. The result set is only like 200 rows, so I'm not getting killed there.

• Online Advetisement/Banner Management System

  - by Sumesh Joshi

  I am developing site for online advertisements where sellers and buyers can come and sell/buy advertisements. Just need to develop detailed statistics like click counts, from which page clicks are coming (one advertisement can be placed on many pages), from which position (top, right, left ...) click are coming (one advertisement can be placed in different position on single page) etc. I seen that most of the advertisement on popular websites has following format: http://ads.stackoverflow.com/a.aspx?Task=Click&ZoneID=3&CampaignID=838&AdvertiserID=50&BannerID=1335&SiteID=1&RandomNumber=1463177307&Keywords=c%23%2c.net%2ccollections%2cdictionary%2chashtable It has many parameters like ZoneID, CampaignID, AdvertiserID, BannerID, SiteID, RandomNumber, adid, adcrid, obid, obtid and way. I can use one advertisement (adid) in multiple pages. But can't figure out the way to distinguish between from which pages clicks are coming. How can I use such parameters to generate statistics which tell me the page from which clicks are coming?

• Multithreaded FTP upload. Is it possible?

  - by Arty

  I need to upload multiple files from directory to the server via FTP and SFTP. I've solved this task for SFTP with python, paramiko and threading. But I have problem with doing it for FTP. I tried to use ftplib for python, but it seems that it doesn't support threading and I upload all files one by one, which is very slow. I'm wondering is it even possible to do multithreading uploads with FTP protocol without creating separate connections/authorizations (it takes too long)? Solution can be on Python or PHP. Maybe CURL? Would be grateful for any ideas.

• Book for a Windows Application

  - by cateof

  Hello everybody. I want to create an small GUI Windows application that looks like all the other usual appz. I am searching for a book that describes the whole procedure. Let's say an address book application that can be have a small database, minimized in the task bar, doing things in the background and so on. I don't care for the language. But I would prefer to do it in .NET C++. I know it is a "very" general question, so Thanks in advance.

• Documenting and defining content types for a CMS or similar project

  - by Rimian

  I'm writing up some documentation on a Drupal project and my task is to define the content types and their attributes. The intended audience is project managers and developers. So it could be a high level document that gives an overview of the system. (I think that's how I describe it: high level rather than high detail) At the moment I'm using open office and bullet points but it seems like an amateurish method when I need to describe details that could be useful for a developer (me). Something like UML would describe detail but is probably more complicated than I need right now and could be too technical for others on the team. Are there any universal methods or templates that I can use to describe information in this case?

• How to send reminder notifications to subscribers for renewal from SQL Server 2005?

  - by codemonkie

  I have a table in SQL DB, namely dbo.subscribers, it contains following columns: -SubscriberID -JoinDateTime The business logic says a subscription last for 2 weeks and a reminder should be sent after 7 days from the JoinDateTime. The way that the system was designed to send reminders are via a URL call, e.g. http://xxx.xxx.xxx.xxx/renew_userid=SubscriberID/ and that can only be called from our webserver which is the only whitelisted IP machines given. Currently there is a windows service written to query the DB once a day at midnight to grab all expiring subscribers and send them reminders, however this batch approach only sends reminders to the nearest date, well, I could have set the interval down from 1 day to 1 hour such that the service can send notifications out closer to the exact JoinDateTime + 7 days requirements. I have heard a stored procedure can be written and perform task like this to a nearly real-time manner, if yes, please give me some hints on how to do it. Another question is - is SSRS bit of an overkill to perform things like this? Please advice. TIA

• Working with foreign keys - cannot insert

  - by Industrial

  Hi everyone! Doing my first tryouts with foreign keys in a mySQL database and are trying to do a insert, that fails for this reason: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails Does this mean that foreign keys restrict INSERTS as well as DELETES and/or UPDATES on each table that is enforced with foreign keys relations? Thanks! Updated description: Products ---------------------------- id | type ---------------------------- 0 | 0 1 | 3 ProductsToCategories ---------------------------- productid | categoryid ---------------------------- 0 | 0 1 | 1 Product table has following structure CREATE TABLE IF NOT EXISTS `alpha`.`products` ( `id` MEDIUMINT UNSIGNED NOT NULL AUTO_INCREMENT , `type` TINYINT(2) UNSIGNED NOT NULL DEFAULT 0 , PRIMARY KEY (`id`) , CONSTRAINT `prodsku` FOREIGN KEY (`id` ) REFERENCES `alpha`.`productsToSku` (`product` ) ON DELETE CASCADE, ON UPDATE CASCADE) ENGINE = InnoDB;

• How would MVVM be for games?

  - by Benny Jobigan

  Particularly for 2d games, and particularly silverlight/wpf games. If you think about it, you can divide a game object into its view (the graphic on the screen) and a view-model/model (the state, ai, and other data for the object). In silverlight, it seems common to make each object a user control, putting the model and view into a single object. I suppose the advantage of this is simplicity. But, perhaps it's less clean or has some disadvantages in terms of the underlying "game engine". What are your thoughts on this matter? What are some advantages and disadvantages of using the MVVM pattern for game development? How about performance? All thoughts are welcome.

• Project management estimating time, budget and product pricing

  - by dr_hoppa

  I have been a software developer for a while but was not interested in the above topics, currently I am put in the position of wanting to learn more about them but don't have a clue where to begin. I have done task estimations and I can do decent ones, but have little/none experience in the field of budget/product pricing and would want to learn more. Do you have any suggestions of good resources that I could look up in order to learn more (eg. books, blogs, ...) This need arised while talking to a friend about management and he brought up management terms that I wasn't aware of (eg. KPI, ...)

• Newbie Question: Read and Process a List of Text Files

  - by johnv

  I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET): Dim tRead As System.IO.StreamReader Public Function ReadFile() As String Dim EntireFile As String tRead = File.OpenText("c:\textexample\00001.txt") EntireFile = tRead.ReadToEnd Return EntireFile End Function Public Function Step1() ..... End Function Public Function Step2() ..... End Function .............. I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file. Any help is greatly appreciated. ReplyQuote

• how to deal with a static analyzer output

  - by Jim

  We have started using a static analyzer (Coverity) on our code base. We were promptly stupefied by the sheer amount of warnings we received (its in the hundreds of thousands) , it will take the entire team a few mounts to clear them all (obliviously impossible). the options we discussed so far are 1) hire a contractor to sort out the warning and fix them - he drawback: we will probably need very experiences people to do all these modifications, and no contractor will have required understanding of the code. 2) filter out the warning and deal only with the dangerous ones - the problem here is that our static analysis output will always be cluttered by warning making it difficult for us to isolate problems. also the filtering of the warning is also a major effort. either way, bringing our code to a state when the static analyzer can be a useful tool for us seems a monumental task. so how is it possible to work with the static analyzer without braining current development efforts into a complete stand still?

• Getting "select permission denied" when using LINQ but my account is a sysadmin

  - by Wayne M

  I have a console app that's geared to be automatically ran as a Scheduled Task. I use LINQ to SQL to pull some data out of the database, format it into a CSV and email it to a client. All of a sudden I am getting the error "SELECT permission denied for table", but the account I'm using to connect to the database (specified in my app.config file) has the "sysadmin" server role (bad programmer, I know; I'll get around to changing it to a better account later but I want to make sure it works first). I can connect directly to the SQL database using that very same account and query the table in question without a problem, it only seems to be when using the LINQ code. Any idea what would be causing this?

• Microsoft Access to SQL Server - synchronization

  - by David Pfeffer

  I have a client that uses a point-of-sale solution involving an Access database for its back-end storage. I am trying to provide this client with a service that involves, for SLA reasons, the need to copy parts of this Access database into tables in my own database server which runs SQL Server 2008. I need to do this on a periodic basis, probably about 5 times a day. I do have VPN connectivity to the client. Is there an easy programmatic way to do this, or an available tool? I don't want to handcraft what I assume is a relatively common task.
