• How to switch off? [closed]

  - by Xophmeister

  While I've programmed software for many years, I've only recently started doing so professionally and have noticed a bit of a problematic pattern. I hope this is the best place to pose such a question, as I am interested in others' experiences and solutions... Writing software is, by its nature, a cerebral exercise. When coding for my own sake, I would do so until I was satisfied; even if that meant going all night. Now I'm coding in exchange for goods and services, on projects that are inherently uninteresting to me, I want to 'switch off' when it's time to go home. Maybe you consider that to be a 'bad attitude', but I just don't feel that whatever I'm working on is worth caring about after-hours. Besides, my employer doesn't exactly have the infrastructure required to make out-of-office changes; I can't just clone a repo and even remote login is a PITA. Anyway, the problem I'm experiencing is that, while I'm not particularly overworked or stressed, if I'm faced with a problem, my brain will work on a solution. Generally, it won't give up. Hence I can't switch off and, sometimes, the problem or the solution is significant enough that it disrupts my sleep. While, paradoxically, this doesn't seem to affect my coding ability, it can have a profound impact of the rest of my life. I get increasingly low as I get tired. So far, the best solutions I've found are writing little notes on the matter (and, say, e-mailing them back to my work address) and exercise. Neither of these can switch me off entirely and, as the week progresses, exercise especially becomes untenable due to tiredness. TL;DR How can you stop from being a coding zombie?

• POLL: How do you build your interfaces in xcode for iphone/coco-touch applications?

  - by LolaRun

  Hi all, It's been 2 months i'm using xcode and building iphone apps, and i'm finding it really hard to grasp the good design for the applications. I always face problems like you can't put your tabbarcontroller in another custom viewcontroller sort of a thing? or other problems... That 'sometimes' - of course - would work if you did the creation of the views/viewcontrollers programmatically. so I don't know if i should start writing the creation of my objects or use interface builder. This is why i'm asking this poll question, to see what's the most accepted way among other developers. I'm not going to answer my question, so the votes would not increase my reputation and risk my poll being closed soon. I prefer that the first two readers of this question should answer by 'using IB' and the second one 'programmatically' and the rest would vote up or down for these two answers. And don't vote my question either, i just need to know, and maybe someone else wants to know. so the longer this question lives the better. and gaining nothing from it concerning reputation would help that cause. thank you all for your cooperation. and go ahead and answer Peace

• During interviews, how do I gauge a company's respect for my position?

  - by Bluu

  I'm a web developer who previously joined a software company not knowing their value and respect went to big data analysis, not their website. Sure, they needed a public-facing website, but I eventually found that the most exciting, valued projects there went to data teams. Realizing this, members of the web team were picked off and switched teams, making it hard for those left behind to keep up the work load, and making us look bad. At times it seemed the company culture sneered at us, wondering, "What does that team even do here?" A friend of mine had the opposite problem at another software company. All he wanted to do was crunch big numbers. However he complained that the rest of the company wouldn't shut up about developing the usability of their website. Meanwhile his analytics team languished. I've also heard of salespeople getting love at a company, while engineering as a whole is undervalued, or vice versa. As for my story, if I could have known the company was like that, I might have avoided the job in the first place. So, before I join a new company, how do I gauge its actual respect for my programming role? For its other roles? I want to avoid companies that aren't serious about my particular focus in programming, or, perhaps bigger picture, companies that don't value everybody who works there. (Note I think gauging the company's attitude toward the basic needs of its programmers is covered by these related questions.)

• MVC: Nasty __o not declared

  - by xamlnotes

  I ran into this little error with MVC where a bunch of errors showed up about  __o  not declared. This was driving me nuts. Then I ran across this link that solved it. http://stackoverflow.com/questions/750902/how-do-i-get-rid-of-o-is-not-declared So, the solution is to put this into the top of the page like VS does for your site.master. <%-- The following line works around an ASP.NET compiler warning --%> <%: ""%> But what about other pages? Lets say you have a view that’s using your site master and that view is throwing this error. Just add the items into the content section where the error occurs like so: <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <%-- The following line works around an ASP.NET compiler warning --%> <%: ""%>   Then add the rest of your code. That seems to fix it and its pretty simple too.

• Will I be able to get programming interviews at good software companies with a non-CS degree?

  - by friend

  I'll be graduating in a year, but I'll have a degree in Economics. I'm pretty much done with my Economics coursework, and by the time next year comes around I will have devoted 1.5 years to learning CS. I will have almost finished the requirements to graduate with a degree in CS, but unfortunately my school requires a science series that would add another 6-9 months of study if I were to try and get the degree (not to mention a max unit cap). I have or will have taken: Objected Oriented Programming Discrete Math Data structures Calculus through multivariable (doubt this matters at all) Linear Algebra (same) Computer Organization Operating Systems Computational Statistics (many data mining projects in R) Parallel Programming Programming Languages Databases Algorithms Compilers Artificial Intelligence I've done well in the ones I've taken, and I hope to do well in the rest, but will that matter if I can't say to the HR people that I have a CS degree? I'd be happy to get an internship at first too, so should I just apply as if I'm an intern and not looking for fulltime, and then try and parlay that into something? Sidenote if you have time -- Is a computer networks or theory of computation class important? Would it be worth taking either of those in lieu of a class on my list? edit -- I know this isn't AskReddit or College Confidential; I know there will be some outrage at posting a question like this. I'm merely looking for insight into a situation that I've been struggling with, and I think this is the absolute best place to find an answer to this question. Thanks.

• How are certain analytics metrics (time on site, etc.) usually distributed?

  - by a barking spider

  I'm not sure if I've come to the right place to ask this question, but I'm gathering some information for a research project. We're trying to design an experiment that'll heavily involve web analytics, and I'm trying to figure out some sensible values of mean +/- standard deviation for the following visitor-level (i.e., visitor 1 spends 2 minutes on site, visitor 2 spends 1 minute -- mean 1.5 +/- 0.71...) metrics: time spent on site page views If time allowed, we would put up the sites and gather the information ourselves, but we have a grant deadline coming up. I realize that even though these the distributions of these quantities are probably going to be heavily skewed towards zero, we'll need some reasonable figures or estimates of these figures in order to do sample size calculations, etc. Anyway, I'm not sure where else I'd turn, and I certainly have had a difficult time finding these values in the prior literature. If someone could direct me to a paper with the right information, or if you have these figures on hand (perhaps taken directly from your logs!) -- that would be amazing, and I'd love to hear from you. Thanks in advance, and even though I'm not allowed to reveal too much, rest assured that this info'll be applied towards a good cause :)

• How to correctly write an installation or setup document

  - by UmNyobe

  I just joined a small start-up as a software engineer after graduation. The start-up is 4 year old, and I am working with the CEO and the COO, even if there are some people abroad. Basically they both used to do almost everything. I am currently on some kind of training phase. I have at my disposition architecture, setup and installation internal documentation. Architecture documentation is like a bible and should contain complete information. The rest are used to give directions in different processes. The issue is that these documents are more or less dated, as they just didn't have the time to change them. I will be in charge of training the next hires, and updating these documents is part of my training. In some there is a lot of hard-coded information like: Install this_module_which_still_exists cd this_dir_name_changed cp this_file_name_changed other_dir_name_changed ./config_script.sh ./execute_script.sh The issues i have faced : Either the module installation is completely different (for instance now there is an rpm, or a different OS) Either names changed, and i need to switch old names by new names Description of the purpose of the current step missing. Information about a whole topic is missing Fortunately these guys are around and I get all the information I want and all the explanations I need. I want to bring a design to the next documents so in the future people don't feel like they are completely rewriting a document each time they are updating it. Do you have suggestions? If there is a lightweight design methodology available online you can point me to it's nice too. One thing I will do for sure is set up a versioning repository for the documents alone. There is already one for the source code so I don't know why internal documents deserve a different treatment.

• Recursive function with for loop python

  - by user134743

  I have a question that should not be too hard but it has been bugging me for a long time. I am trying to write a function that searches in a directory that has different folders for all files that have the extension jpg and which size is bigger than 0. It then should print the sum of the size of the files that are in these categories. What I am doing right now is def myFuntion(myPath, fileSize): for myfile in glob.glob(myPath): if os.path.isdir(myFile): myFunction(myFile, fileSize) if (fnmatch.fnmatch(myFile, '*.jpg')): if (os.path.getsize(myFile) > 1): fileSize = fileSize + os.path.getsize(myFile) print "totalSize: " + str(fileSize) THis is not giving me the right result. It sums the sizes of the files of one directory but it does not keep suming the rest. For example if I have these paths C:/trial/trial1/trial11/pic.jpg C:/trial/trial1/trial11/pic1.jpg C:/trial/trial1/trial11/pic2.jpg and C:/trial/trial2/trial11/pic.jpg C:/trial/trial2/trial11/pic1.jpg C:/trial/trial2/trial11/pic2.jpg I will get the sum of the first three and the the size of the last 3 but I won´t get the size of the 6 together, if that makes sense. Thank you so much for your help!

• Build 2013&ndash;Keynote Thoughts

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/06/26/153243.aspxSome thoughts on the Build 2013 keynote. They Listened to Feedback while Keeping to their Plans I am one of the people in the “bring back the start menu” camp. I want my start menu. I *like* my start menu. Microsoft heard that and put it back, fantastic. But they implemented it in a way that still pushes the Windows 8 UI – and I’m actually pretty happy with it. When you hit the Start menu, you get the live-tiles displayed overlaying the desktop. But you can also swipe from the bottom to get the “all-applications” view. This, in essense, is really what those that like the Start Menu want. I believe it was mentioned that you can configure the all-applications view to be the default. They’re Committed to Improving Windows 8 The commitment to rapid deployments Ballmer talked about is crucial to Windows 8’s success. They need to keep it evolving quickly to maintain the interest of users and developers. I think the little improvements they showed are excellent (hands-free mode, multi window docking, better multi-monitor support, new developer controls, etc.). Hardware Vendors are Committed to Windows 8 They showed off a number of new hardware products (Windows 8 and Windows Phone). The Surface’s introduction to the market has done nothing to dissuade their hardware partners. Bing as a Platform is Huge for Developers!!! This was the biggest take-away from the keynote! What the team is doing with Bing not as a search engine but as a developer API is very impressive! I’m going to be diving into this over the rest of Build so watch more blog posts coming on it. Azure, Office 365, and other topics will be covered at tomorrow’s keynote. So far, great kick off to Build. Now on to sessions! D

• SharePoint Saturday Huntsville Wrap Up

  - by Mark Rackley

  So, Cathy Dew (@catpaint1) and company put on a great SharePoint Saturday event this past weekend. I got to hang out with some old friends and meet some new ones. I’d list you all, but I’d undoubtedly miss someone and don’t want to offend anyone.  Although I find it odd that I see @MossLover now more since she moved to New Jersey than when she lived next door in Kansas City… what’s up with that? Anyway, Cathy did a tremendous job organizing the event.  Everything went smoothly and everyone had a great time. Maybe I can talk her into organizing the rest of SharePoint Saturday Ozarks on June 12th… you know that’s coming up? right? While you’re here why not go ahead and register right now at: http://spsozarks.eventbrite.com/  Yes.. that was a shameless plug… I did my default presentation on “Wrapping Your Head Around the SharePoint Beast”. This continues to be my most popular presentation. I try to tweak it every time and I always have fun doing it. I get to pick on people and they pick on me back, but I always manage to learn something new when I present it. I had a great interactive crowd and they didn’t throw anything at me.  All in all I consider it a success.  Thanks for coming if you attended!  You can get the slides here:  SharePoint Saturday Huntsville - Wrapping Your Head Around the SharePoint Beast Next up for me is SharePoint Saturday DC on May 15th.  Wow this is going to be a huge event with space for 1500 attendees.. no, that is not a typo!  Stop me and say hi if you are able to make it!!

• Most common parts of a SELECT SQL query?

  - by jnrbsn

  I'm writing a function that generates a SELECT SQL query. (I'm not looking for a tool that already does this.) My function currently takes the following arguments which correspond to different parts of the SELECT query (the base table name is already known): where order fields joins group limit All of these arguments will be optional so that the function generates something like this by default: SELECT * FROM `table_name` I want to order the arguments so that the most often used parts of a SELECT query are first. That way the average call to the function will use as few of the arguments as possible rather than passing a null value or something like that to skip an argument. For example, if someone wanted to use the 1st and 3rd arguments but not the rest, they might have to pass a null value as the 2nd argument in order to skip it. So, for general purpose use, how should I order the arguments? Edit: To be more precise, out of the query parts I listed above, what is the order from most used to least used? Also, I'm not looking for solutions that allow me to not have to specify the order. Edit #2: The "fields" argument will default to "*" (i.e all fields/columns).

• Simple C: How do I scan this information in properly?

  - by Doc

  OK this is a simple question but for some reason I just can't get it right. I have to scan from a file hundreds of lines of code and store it in a array (which I can normally do a ok job with) however At one point the code will specify a number that then corresponds to the next batch of chars ints and floats going into various arrays. As I know I am not describing this correctly here is a example. one line of the file I am reading will contain something close to this. 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom the problem I am having is This part here 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom The rest after this is Generally the exact same however at this point the number at the front descides all the values that are going in. I am almost completely lost on how to write a way that can scan this and store the data into arrays correctly

• How Do You Get Answers?

  - by Grant Fritchey

  We all learn differently. Some people really prefer to sit with a book. Others need class room time, with an instructor. Still others just want to do things themselves until they figure them out. And sometimes, it's all of the above. Since we all learn differently, is it any surprise that we ask questions differently? Some of us are going to want to phrase a very focused question that should yield a limited and concise answer. Others are going to want to have a long involved discussion with possible variations. There are those among us who will want to know whether or not their peers agree with a given answer. Still more are going to want to see lots of points of view dished out so they can understand things in a different way. Many of us want to know when a question has been asked that there is a hard, well defined answer. The rest are willing to read through a bevy of answers and discussion, deciding for ourselves who has come up with the best solution. Where am I going with this? Excellent question. Since we all ask questions in different ways isn't it great that we have places to go that let us ask questions and get answers in a way that's best suited to our individual preferences. Do you want the long-running discussion format? Then you should be hanging out on the forums over at SQL Server Central. Do you want specific answers with direct peer evaluation of the strength of those answers? Then you should be hanging out on the forums over at Ask SQL Server Central. You can get answers to your questions, and do it in a way that's most comfortable for you.

• why does array initialization in function other than main is temporary? [on hold]

• How often do you review fundamentals?

  - by mlnyc

  So I've been out of school for a year and a half now. In school, of course we covered all the fundamentals: OS, databases, programming languages (i.e. syntax, binding rules, exception handling, recursion, etc), and fundamental algorithms. the rest were more in-depth topics on things like NLP, data mining, etc. Now, a year ago if you would have told me to write a quicksort, or reverse a singly-linked list, analyze the time complexity of this 'naive' algorithm vs it's dynamic programming counterpart, etc I would have been able to give you a decent and hopefully satisfying answer. But if you would have asked me more real world questions I might have been stumped (things like how would handle logging for an application, or security difference between GET and POST, differences between SQL Server and Oracle SQL, anything I list on my resume as currently working with [jQuery questions, ColdFusion questions, ...] etc) Now, I feel things are the opposite. I haven't wrote my own sort since graduating, and I don't really have to worry much about theoretical things that do not naturally fall into problems I am trying to solve. For example, I might give you some great SQL solutions using an analytical function that I would have otherwise been stumped on or write a cool web application using angular or something but ask me to write an algo for insertAfter(Element* elem) and I might not be able to do it in a reasonable time frame. I guess my question here to the experienced programmers is how do you balance the need to both learn and experiment with new technologies (fun!), working on personal projects (also fun!) working and solving real world problems in a timeboxed environment (so I might reach out to a library that does what I want rather than re-invent the wheel so that I can focus on the problem I am trying to solve) (work, basically), and refreshing on old theoretical material which is still valid for interviews and such (can be a drag)? Do you review older material (such as famous algorithms, dynamic programming, Big-O analysis, locking implementations) regularly or just when you need it? How much time do you dedicate to both in your 'deliberate practice' and do you have a certain to-do list of topics that you want to work on?

• handling multiple interviews / offers [closed]

  - by farble1670

  What's the best way to handle a situation where you have, or expect to have multiple offers? The ideal situation is that your several offers come in about the same time, and you make a choice. this is not how it happens though. You may have an offer, and several near-final interviews lined up for the following days or weeks. One way to handle it would be to ask for a longer time to decide on the first offers you receive. 2 weeks? This gives time to rush the rest of the things you have going through to an end. i question whether asking for 2 weeks to decide is reasonable though. My guess is that an employer would see through that and force your hand. Another way to handle it would be to accept the first offer, and ask for a reasonable period before your start date, then simply "quit" the first position before you ever start if something better comes along. On one hand, employment is at-will, and employers exercise this fact regularly. On the other hand, it seems morally the wrong thing, and has the potential to burn some bridges. And of course the last option is to simply evaluate each offer in isolation, and accept or reject within the given time frame. any thoughts?

• Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

  - by ismaelf

  I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

• XNA 2D vehicle wall collisions

  - by mike

  I am attempting to implement collisions for my truck game, where the truck can drive around the world and hit walls surrounding the level and various randomly placed walls within the level. I am able to get direct collisions working correctly. However, it is getting very complicated and tricky very quickly. I am trying to accommodate various other collisions such as when a truck is against the wall then turns an adjacent direction or when they reverse into a wall. Both of these result in a slight collision as the image of the truck flips around to the direction the player wants to move. All of this has resulted in a whole lot of if statements to check how I should be fixing the collision. This in turn makes the player jump to random locations and "teleport" around corners, etc. The rest of my game is fine, I am not completely new to game development or C# for that matter. It's just the logic of collisions. Any ideas on how I can approach this? Image of the collisions I am trying to resolve: http://tinypic.com/r/2qtflvq/6

• Are small amounts of functional programming understandable by non-FP people?

  - by kd35a

  Case: I'm working at a company, writing an application in Python that is handling a lot of data in arrays. I'm the only developer of this program at the moment, but it will probably be used/modified/extended in the future (1-3 years) by some other programmer, at this moment unknown to me. I will probably not be there directly to help then, but maybe give some support via email if I have time for it. So, as a developer who has learned functional programming (Haskell), I tend to solve, for example, filtering like this: filtered = filter(lambda item: included(item.time, dur), measures) The rest of the code is OO, it's just some small cases where I want to solve it like this, because it is much simpler and more beautiful according to me. Question: Is it OK today to write code like this? How does a developer that hasn't written/learned FP react to code like this? Is it readable? Modifiable? Should I write documentation like explaining to a child what the line does? # Filter out the items from measures for which included(item.time, dur) != True I have asked my boss, and he just says "FP is black magic, but if it works and is the most efficient solution, then it's OK to use it." What is your opinion on this? As a non-FP programmer, how do you react to the code? Is the code "googable" so you can understand what it does? I would love feedback on this :) Edit: I marked phant0m's post as answer, because he gives good advice on how to write the code in a more readable way, and still keep the advantages. But I would also like to recommend superM's post because of his viewpoint as a non-FP programmer.

• How to Keep SEO Score from Dropping with Duplicate Content

  - by joeh0717

  I'm hoping that someone has a solution for what I'm trying to accomplish. I'm working on a travel agency web site and there's a "Overview" section for each cruise line. These overviews are located on the index page for each cruise line. Here's my issue: The company is creating a search engine that includes details on each cruise line. Their write-ups on each cruise line are great, so I'd like to include the overview they created for each cruise line, rather than having to create all new ones. However, I don't want duplicating their content to negatively affect the SEO scores of the pages they originally put this content on. It's gong to duplicate, since each page that's dynamically generated by their search engine is going to include a section about the cruise line (where I'd want to place the overview). Question: Is there any way that I can include these overviews (ideally, copying the exact HTML that they've already implemented) without the search engines indexing those particular code sections? I'd want the rest of the search result pages to be indexed...just not the section of each page that contains this duplicate code. I saw something about using a span class named robots-nocontent in Yahoo (not sure if this also applies to Bing) and googleon / googleoff tags in Google. Is this the best solution? I'm open to any suggestions, thanks!

• What is causing this behavior with the movement of Pong Ball in 2D? [closed]

  - by thegermanpole

  //edit after running it through the debugger it turned out i had the display function set to x,x...TIL how to use a debugger I've been trying to teach myself C++ SDL with the lazyfoo tutorial and seem to have run into a roadblock. The code below is the movement function of my Dot class, which controls the ball. The ball seems to ignore yvel and moves with xvel to the bottom right. The code should be pretty readable, the rest of the relevant facts are: All variables are names Constants are in caps dotrad is the radius of my dot yvel and xvel are set to 5 in the constructor The dot is created at x and y equal to 100 When I comment out the x movement block it doesn't move, but if i comment out the y movement block, it keeps on going down to the right. void Dot::move() { if(((y+yvel+dotrad) <= SCREEN_HEIGHT) && (0 <= (y-dotrad+yvel))) { y+=yvel; } else { yvel = -1*yvel; } if(((x+xvel+dotrad) <= SCREEN_WIDTH) && (0 <= (x-dotrad+xvel))) { x +=xvel; } else { xvel = -1*xvel; } }

• It is not quantifiably better

  - by MarkPearl

  An interesting statement I have heard recently in one of the organizations that I have been working with is that some of the agile processes that we are implementing are not quanitfiably better than the traditional processes they had before. This seemed to be the motivation for not moving the new process to the rest of the organization or expanding it. They would say, “the team seems to be happier than they were before but the improvement is not quanitifiable and until we can quantify it on paper we cannot make any further changes”. Up till recently I thought this was a problem until it dawned on me that their existing system was not being quantified, meaning even if I managed to quantify what we were doing (which I can), what would we be comparing it to? An appropriate response to someone when they give this reasoning is - "That's a very good point, let's go over the quantifiable attributes of your existing processes and see if we can get some common metric that we can compare them on?" If they then are able to produce some quantifiable metrics, you win because you now have something to compare it to, and if they don't then you can politely point the logic of that out as well.
