• I'm graduating with a Computer Science degree but I don't feel like I know how to program.

  - by Wendy Peters

  I'm graduating with a Computer Science degree but I see websites like Stackoverflow and search engines like Google and don't know where I'd even begin to write something like that. During one summer I worked as a iPhone developer, but I felt like I was mostly gluing together libraries that other people had written with little understanding of what's happening underneath the hood. I'm trying to improve my knowledge by studying algorithms, but it is a long and painful process. I find algorithms difficult and at the rate I am working through my book it will a decade will have passed before I will finish. Given my current situation, I've spent a month looking for work but my skills (C, Python, Objective-C) are not so desirable in the local market, where C#, Java, and web development are much higher in demand. My GPA is ok (3.0) but it's not high enough to apply to the large companies or return for graduate studies and I don't have a good network of friends. Basically I'm graduating with a Computer Science degree but I don't feel like I know how to program. I thought that joining a company and programming full-time would give me a chance to develop my skills and learn from those more experienced than myself, but I'm struggling to find work and am starting to get really frustrated. I am going to cast my net wider and look beyond the city I've grown up in, but what have other people in similar situation tried to do?

• How to Get Dictionary<int, string> from Linq to XML Anonymous Object?

  - by DaveDev

  Currently I'm getting a list of HeaderColumns from the following XML snippet: <HeaderColumns> <column performanceId="12" text="Over last month %" /> <column performanceId="13" text="Over last 3 months %" /> <column performanceId="16" text="1 Year %" /> <column performanceId="18" text="3 Years % p.a." /> <column performanceId="20" text="5 Years % p.a." /> <column performanceId="22" text="10 Years % p.a." /> </HeaderColumns> from which I create an object as follows: (admitedly similar to an earlier question!) var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new { PerformanceId = (int)column.Attribute("performanceId"), Text = (string)column.Attribute("text") }).ToList(), }).ToList() }; I'd like if HeaderColumns was a Dictionary() so later I extract the values from the anonymous object like follows: Dictionary<int, string> myHeaders = new Dictionary<int, string>(); foreach (var column in performancePanels.Panels[0].HeaderColumns) { myHeaders.Add(column.PerformanceId, column.Text); } I thought I could achieve this with the Linq to XML with something similar to this HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new Dictionary<int, string>() { (int)column.Attribute("performanceId"), (string)column.Attribute("text") }).ToDictionary<int,string>(), but this doesn't work because ToDictionary() needs a Func parameter and I don't know what that is / how to implement it, and the code's probably wrong anyway! Could somebody please suggest how I can achieve the result I need? Thanks.

• Data Warehouse: Modelling a future schedule

  - by Pat

  I'm creating a DW that will contain data on financial securities such as bonds and loans. These securities are associated with payment schedules. For example, a bond could pay quarterly, while a mortage would usually pay monthly (sometimes biweekly). The payment schedule is created when the security is traded and, in the majority of cases, will remain unchanged. However, the design would need to accomodate those cases where it does change. I'm currently attempting to model this data and I'm having difficulty coming up with a workable design. One of the most commonly queried fields is "next payment date". Users often want to know when a security will pay next. Therefore, I want to make it as easy as possible for them to get the next payment date and amount for each security. Also, users often run historical queries in which case they'd want the next payment date and amount as of a specific point in time. For example, they may want to look back at 1/31/09 and query the next payment dates (which would usually be in February 2009 for mortgages). It's also common that they want to query a security's entire payment schedule, which might consist of 360 records (30 year mortgage x 12 payments/year). Since the next payment date and amount would be changing each month or even biweekly, these fields wouldn't seem to fit into a slow-changing dimension very well. It would probably make more sense to use a fact table, but I'm unsure of how to model it. Any ideas would be greatly appreciated.

• php cURL. preg_match , extract text from xhtml

  - by Michael

  I'm trying to extract the price from the bellow html page/link using php cURL and preg_match . Basically I'm expecting for this code to output 4,550 but for some reasons I get Notice: Undefined offset: 1 in C:\wamp\www\test.php on line 22 I think that the pattern is correct because if I put the html itself in a variable and escape the "" it works ! . Also if I output (echo $result;) it displays the html properly grabbed from foxtons website so I just can't figure it out why the whole thing doesn't work . I need to make this work and also I would appreciate if you would tell me why is that notice generated and why my current script doesn't work. $url = "http://www.foxtons.co.uk/search?bedrooms_from=0&property_id=727717"; $ch = curl_init($url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($ch); curl_exec($ch); curl_close($ch); $result2 = str_replace('"', '\"', $result); $tagname1= ");<\/script "; $tagname2= "<\/noscript per month<\/a"; $pattern = "/$tagname1(.*?)$tagname2/"; preg_match($pattern, $result, $matches); $prices = $matches[1]; print_r($prices); ?

• How important is the .NET programming language when you choose a new job?

  - by Luhmann

  We are currently hiring at the company where I work, and here the codebase is in VB.Net. We are worried that we miss out on a lot of brilliant programmers, who would never ever consider working with VB.Net. My own background is Java and C#, and I was somewhat sceptical as to whether it would work out with VB, as - to be honest - i didn't care much for VB. After a month or so, I was completely fluent in VB, and a few months later i discovered to my surprise, that I actually like VB. I still code my free time projects in C# and Boo though. So my question is firstly, how important is language for you, when you choose a new programming job? Lets say if its a great company, salary is good, and generally an attractive work-place. Would you say no to the perfect job, if the language wasn't your preferred dialect? VB or C# is one thing, but how about Java or C# etc. Secondly if the best developers won't join your company because of your language or platform, would you consider changing, to get the right people? (This is not a language bashing thread, so please no religious language wars) NB: This is Community Wiki

• Should a developer write their own test plan for Q/A?

  - by Mat Nadrofsky

  Who writes the test plans in your shop? Who should write them? I realize developers (like me) regularly do their own unit testing whilst developing and in some cases even their own Q/A depending on the size of the shop and the nature of the business, but in a big software shop with a full development team and Q/A team, who should be writing those official "my changes are done now" test plans? Soon, we'll be bringing on another Q/A member to our development team. My question is, going forward, is it a good practice to get your developers to write their own test plans? Something tells me that part of that might make sense but another part might not... What I like about that: Developer is very familiar with the changes made, thus it's easy to produce a document... What I don't like about that: Developer knows how it's supposed to work and might write a test plan that caters to this without knowing it. So, with the above in mind, what is the general stance on this topic? I'm of course already reading books like the Mythical Man-Month, Code Complete and a few others which really do help, but I'd like to get some input from the group as well.

• Most watched videos this week

  - by Jan Hancic

  I have a youtube like web-page where users upload&watch videos. I would like to add a "most watched videos this week" list of videos to my page. But this list should not contain just the videos that ware uploaded in the previous week, but all videos. I'm currently recording views in a column, so I have no information on when a video was watched. So now I'm searching for a solution to how to record this data. The first is the most obvious (and the correct one, as far as I know): have a separate table in which you insert a new line every time you want to record a new view (storing the ID of the video and the timestamp). I'm worried that I would quickly get huge amounts of data in this table, and queries using this table would be extremely slow (we get about 3 million views a month). The second solution isn't as flexible but is more easy on the database. I would add 7 columns to the "videos" table (one for each day of the week): views_monday, views_tuesday , views_wednesday, ... And increment the value in the correct column based on the day it is. And I would reset the current day's column to 0 at midnight. I could then easily get the most watched videos of the week by summing this 7 columns. What do you think, should I bother with the first solution or will the second one suffice for my case? If you have a better solution please share! Oh, I'm using MySQL.

• How can I efficiently manipulate 500k records in SQL Server 2005?

  - by cdeszaq

  I am getting a large text file of updated information from a customer that contains updates for 500,000 users. However, as I am processing this file, I often am running into SQL Server timeout errors. Here's the process I follow in my VB application that processes the data (in general): Delete all records from temporary table (to remove last month's data) (eg. DELETE * FROM tempTable) Rip text file into the temp table Fill in extra information into the temp table, such as their organization_id, their user_id, group_code, etc. Update the data in the real tables based on the data computed in the temp table The problem is that I often run commands like UPDATE tempTable SET user_id = (SELECT user_id FROM myUsers WHERE external_id = tempTable.external_id) and these commands frequently time out. I have tried bumping the timeouts up to as far as 10 minutes, but they still fail. Now, I realize that 500k rows is no small number of rows to manipulate, but I would think that a database purported to be able to handle millions and millions of rows should be able to cope with 500k pretty easily. Am I doing something wrong with how I am going about processing this data? Please help. Any and all suggestions welcome.

• Is there any way to configure what reCAPTCHA is actually displaying?

  - by trejder

  Is there any way to control, what kind of image is displayed to user in reCAPTCHA or what kind of puzzle he/she is required to solve? I noticed at least two significant changes to what reCAPTCHA is serving (and I must admit, that I don't much like these changes): For years reCAPTCHA was serving two words from scanned books and user was required to solve one of them. They were clearly readable (even those "second" ones, that could be ommitted) and with nearly no problem in solving them by a human. For past few month, I noticed a significant change at all of my sites, that are using reCAPTCHA. They started to show combination of computer-generated long numbers string and something, that looks for me as street/house number photographed in Google StreetView. They're even easier to solve, but what is most important -- it started to happen more and more often that user is obligated to solve both of them. Now, I have noticed another change/regression. Now some of my sites remain at so called "level 2" (like above) and some of them started to serve two words again ("level 1"?). And again, there are more and more situations, where solving both words is required. But, what is most important, on this "level" words are nearly impossible to solve (on my old mobile devices with 3.5'' display I need 5-6 attempts to pass on!). They're cluttered, written in some strange font, mostly in italics with a lot of black and white stains or drops on letters etc. Plus: reCAPTCHA stopped to be equal -- some of my pages are still serving "level2" while some of them are "killing" end users with a need to solve "level3". Is there anyway, I can control this -- force it to use only "level2" and on all my pages? (of course, I'm using exactly the same piece of code to serve reCAPTCHA on all my pages) Note, that I'm not asking for something like in this question. I don't want to change what reCAPTCHA shows (to disable words in favor of only numbers for example). I only want to control, which "version" of puzzles (among described above) reCAPTCHA shows and I want to make it equal on all my sites.

• Can I place AdSense ads on a site with drug content?

  - by Joe Majewski

  I am going to be opening a new WordPress blog today, and I was curious to know if my site will be appropriate for AdSense ads. First off, the blog is going to be about drug addiction. More specifically, opiate addiction. I myself was addicted to pain killers for three years, and I am pleased to say that I am now in treatment and I have not used in over a month now. :) Anyways, my site will be an informative blog about opiates and the harm that they can induce on one's life. It will in no way endorse the use of drugs, but I may talk about my negative experiences. It will be 100% (without a doubt) evident upon checking out my website that my view on drugs is negative. Two questions: (1) Is this content acceptable for Google's terms of service? (2) In order to begin displaying AdSense ads, is there anything I must first do? I already have AdSense ads running on one of my domains. Can I simply begin pasting the code snippets into my new domain and watch as the ads begin to work? Thanks for your time. :)

Could somebody please suggest how I can achieve the result I need? Thanks.

• Error with zoomStartTime and AnnotatedTimeLine

  - by user973025

  I'm a bit of a beginner with Javascript, but last month I had a working Google chart linked to a Google Docs file, which uses a start date for the graph at 90 days before the current date. I checked the page today and in Chrome I get the message "Object # has no method 'getTime'", and in Firefox I get the message "b.zoomStartTime[y] is not a function". Both stop the graph from loading. I have simplified the code to help me with the error, but I'm not getting anywhere... Here's the code: <script type="text/javascript"> var oldDate = new Date(); oldDate.setDate(oldDate.getDate() - 90); </script> <script type="text/javascript" src="//ajax.googleapis.com/ajax/static/modules/gviz/1.0/chart.js"> { "dataSourceUrl": "//docs.google.com/spreadsheet/tq?key=0AkQH6d2CUv_qdDhwd3gtZzdTVFlNX3AwX2xUSUVuclE&transpose=0&headers=-1&range=A1%3AB2436&gid=0&pub=1", "options": { "zoomStartTime": oldDate, "width": 650, "height": 371 }, "chartType": "AnnotatedTimeLine", } </script> Any ideas would be hugely appreciated.

• Reporting Services 2005 - Parameter reliant on cascading parameters

  - by sHr0oMaN

  Good day I have the following: In a SSRS 2005 report I have three report parameters: FinancialPeriodType ("Month" or "Week" in a DropDownList), FinancialPeriod (cascading DropDownList populated depending on first selection) and another parameter, OpeningBalance, of type float. The first two parameters are cascading i.e. the first parameter is used by the query populating the second's available values. This works fine. What I'm attemping to do is default the value of OpeningBalance to a value from a dataset populated by a stored procedure which takes in the first two parameters. However as soon as I select a value for the first parameter, I get the following error: An error occurred during report processing. The value for the report parameter 'OpeningBalance' is not valid for its type.' I've tried setting the default of the second parameter to be a meaningful default (something like 200901) as well as defaulting the second parameter in the SQL store procedure with no affect. Using SQL Profiler I've noticed that selecting a value for the first parameter doesn't even execute the SQL used to obtain available values for the second parameter.

• MTD Expression on a single column - SSRS

  - by Eric

  I need a bit of help here. I have been unable to create an 'Month To Date' expression to a single column on SSRS. I tested the following expression from a similar question in the forum, but it gives me a squiggly line below the variable 'd' =IIF(Fields!CreateDate.Value >= DateAdd(d,-7,Today()), Sum(Fields!Sales.Value), 0) If I run it, of course I got an error telling me that 'd' is not declared. ;) I changed it to ... DateAdd("d",-7,Today()), Sum(Fields!Sales.Value) ... following the example and the squiggly goes below the brackets of "today()" and needless to say it...but still not working. I tried a Dateadd(mm..Datediff ... and still nothing. My report has the following columns: Country | CustomerName | Sales | InvNotProcessed | Open Order | Orders | TotalbyCust What I need is to show the new MTD sales only in the column named "Sales" while the other three shows the rest of the query, which should be open as some orders may take quite a while to manufacture and invoice. the last column sums the totals of all other columns. Any help will be much appreciated. Regards, Eric

• Is there anything on a local network or desktop environment that could effect JScript execution?

  - by uku

  I know this sounds odd. The JS on my project functions perfectly, except when the web site is accessed using computers at one specific company. To make things even more difficult, the JS fails only about 50% of the time when run from that company. The JS failure occurs with FireFox, Chrome, and IE. I have tested this myself using FF and Chrome on a thumb drive. The browsers on my thumb always display my project site perfectly, except when run from a computer on said company's network where they fail at the same rate as the installed browsers. My JS is using jQuery and making some Ajax calls. The Ajax calls are where the failure is occurring. To diagnose the problem I created a logging function for my Ajax calls and recorded success and failure. Over a one month period, there were only a handful of failures (about 1%) from all access points other than this company. Oddly enough, the Ajax calls in the logging function are not failing. There is nothing exotic there - Just Win XP SP3. I have never noticed any other unusual behavior from their network. The company is a division of a mega ISP and is on their corporate network. Any other suggestions for troubleshooting would be welcome.

• Drupal module for complex hours of operation / office hours

  - by Eronarn

  Background: I am building a website in Drupal that links together a wide variety of social service providers for the purposes of discovery, collaboration, and all that good stuff. The goal is to make a website that is simple to browse for consumers of these services and simple to update for providers of these services. The beta has been very well received, but I want to switch to a different information schema before the site goes live. Specific question: I am looking for a module (or other solution) that... Stores this data in Drupal (i.e., no GCal) Supports a wide variety of repeats Is intuitive for people editing the node (no Cron-style interfaces, please!) I have looked into several modules on drupal.org and none seem to meet all of these criteria. I've also searched here, and while this question is similar: http://stackoverflow.com/questions/2794149/drupal-create-a-node-with-employee-working-hours my needs are too complex for the offered solution. Some of these providers have "hours" such as "the third Wednesday of every month", or "open during Winter months", or separate hotline & office hours. Likewise, the Date Repeat module doesn't cut it as stands currently. I'm comfortable hacking what I need into an existing module - I just don't want to duplicate effort! If you have a suggestion on what module might be a good starting point, I'd appreciate that input, too. Thanks. <3

• asp.net gridview bind dateformat not working with update

  - by Brabbeldas

  I have a GridView with a TemplateField column which shows a DateTime from a DataSource. <Columns> <asp:CommandField ShowEditButton="True" /> <asp:TemplateField HeaderText="Start Date"> <EditItemTemplate> <asp:TextBox ID="txtDateStart" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'</asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> Displaying the date in the correct format works as it should. Note that the format starts with DAY followed by MONTH. When I switch to edit mode, change the date in the TextBox to '31-01-2013' and press the GridView's update-link i get an error: Cannot convert value of parameter 'dtDateStart' from 'System.String' to 'System.DateTime' The error is generated by the GridView not my own code. It happens before the UpdateMethod of my DataSource is called. When i type '01-31-2012' the data is processed correctly and the value is updated into the database. Somehow when the date is displayed it uses format dd-MM-yyyy (just as I need it to) But when it reads the new value form the TextBox it uses MM-dd-yyyy Can somebody please help me?

• Book/topic recommendations for a programmer returning to programming.

  - by Jason Tan

  I used to be a developer in Java, PHP, perl and C/C++ (the C++ bit badly - the others not too badly, I hope). This was back in the Java 1.3/1.4 days. We used raw JDBC, swing, servlets, JSP and ant (sometimes even make). Eclipse was new. Then I joined a deployment team and became a deployment engineer and then after the deployment engineer work became a full time sys admin.You get the idea - my experience is a generation or two old in programming terms - maybe older. I'm interested in getting back into Java and perhaps Ruby development, but feel I will be waaaaay behind the technological 8 ball. Can you folks suggest some books (or sites) that would be worth reading to catch up with the last 5-10 years of the development world. I.e. what should I read to try and catch up with where development is now? I see lots of stuff on the web, but what are people in the fabled "real world" using? (are lots of people being SOA based apps? Are they using XP methodology) The sorts of things I'm interested in finding out about/catching up on are: Methodologies Design patterns APIs/Frameworks/Technologies Other stuff you deem current/interesting/relevant. So if you have any thoughts or can recommend any books (especially new classics - you know the 's equivalent to K&R C or "The mythical man month"). Thanks for any thoughts you might share.

• Why is short project lifetime and other situation-specific reasons used to excuse crappy code? [clos

  - by sharptooth

  Every now and then (including on SO) people say things implying that "if the project is short lived you can leave obvious defects there" or "that memory leak only accounts for 100 bytes per whole program lifetime and could be left". Now in my practice I always reuse company-owned code to the greatest extent I can. Like if I need something and I can find it in the company codebase I take it from there and reuse or adapt. This means that any crappy code will be reused as well and I might notice or not notice defects therein. So the defect in some "test we only need for a month" can slip into a proram we ship to customers. And a leak that "only accounted for 100 bytes per lifetime" now could account for 100 bytes 10 times per second in a server application intended to run for months. That's why I don't understand why excuses like that are offered. Is our compamy the only one having a source control? Or are we the only company that requires writing human-readable code? Could anyone shed a light on why people seriously offer such excuses?

• breaking datetime into constituent parts ASP.NET MVC form

  - by nick

  hi guys, i have searched the web relentlessly for this and have not found anything - which is surprising because i would think it is such a common scenario! Basically, on my model i have a DateTime field which i wish the user to populate through a form. I am using the Html helper to render all other parts of the form (along with validation) So this question is in two parts... Html Helper Firstly, is there any way to use the Html helper to split the DateTime field to be rendered as the three constituent parts of a date: day, month, year (since i do not care about the time part). This could be rendered as text boxes, drop down lists or a combination of both. Model Binding And then when the form is posted, what is the best approach for binding back up to the model? I have seen Scott Hanselmann's solution to this, but it seems a little bloated for what i need - i was hoping for a slightly more elegant solution. Is it recommended to extend DefaultModelBinder and set that as default binder (since all dates would be handled in this way) or write a class that implements IModelBionder and set it as the default binder for the DateTime type? Thanks for all the help in advance :-) i'm loving MVC but it's infuriating me that something so trivial is causing so much headaches!

• Looking for an issue tracker / project management software that automatically manages start/completion dates based on priority/relationships

  - by user361910

  So, a little background. We are a small company with a half-dozen developers. We have been evaluating many project management / issue tracking software packages (TRAC, Redmine, FogBugz, etc) and trying to create a decent process/workflow for managing projects, adding features, fixing bugs, etc. I'd like to think our requirements are similar to most other companies our size. Essentially, what this comes down to is 1) An easy way for the PM and developers to track projects, issues, bugs, etc 2) An easy way for the PM and admin/executives to get a birds-eye view of progress and easily manage timelines, schedules, and priorities. After trying TRAC, we moved to Redmine. We found Redmine to be easier than track to administer and the ability to have sub-projects and sub-tickets is great. However, the big problem we ran into is the fact that it is very difficult to manage schedules and timelines. It seems like it would be incredibly time-intensive to manage because you have to manually enter a start date, estimated time, and end date for each ticket, project, etc. So if you setup a month's schedule based on priorities, what are you supposed to do when a particular ticket/issue/subproject takes up more time than was estimated. Right now, it appears I would have to go back in and MANUALLY change the start/end date of every single item. What would be ideal is to be able to set priorities/dependencies and estimated time on tickets/milestones, and have the software automatically manage the start/end dates. Does anyone know how to get Redmine to do this, or recommend a different software package that can do something like this!

• What should a teen dev do for practical experience in development?

  - by aviraldg

  What should a teen dev do for practical experience? If you want more details , then read on: I learnt programming when I was 9 , with GWBASIC (which I now hate) , which was what was taught @ school. That was done in a month. After that I learnt C++ and relearnt it (as I didn't know of templates and the STL before that) Recently I learnt PHP , SQL and Python. This was around the time I switched over to Ubuntu. I'd always loved the "GNUish" style of software development so I jumped right in. However , most of the projects that I found required extensive knowledge of their existing codebase. So , right now I'm this guy who knows a couple of languages and has written a couple of small programs ... but hasn't gone "big", if you get it. I would love suggestions of projects that are informal and small to medium sized , and do not require much knowledge of the codebase. Also note that I've looked at things like Google Summer of Code and sites like savannah.gnu.org and the first doesn't apply , since I'm still in school and the latter either has infeasable projects , or things that are too hard.

• Full and Partial Matching of Sets

  - by jeffrey

  I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}
