• As a programmer how do I plan to learn new things in my spare time

  - by priyank patel

  I am a Asp.Net/C# developer, I develop few projects in my spare time. I try to utilize my time as much as I can. I have been working for past 7 months. Suddenly these days I am a bit worried about learning the new stuff that is there for me as a programmer. I develop in my spare time so I don't get enough time to read books or blogs. So my question to some of you guys is how should I plan to learn new things, should I at least dedicate two-three evenings for new stuff, maybe ebooks while travelling is a good option too. How do you people plan to learn,should I also start to develop with whatever I learnt? As far as learning is concerned, should I just pick up the basics and then implement it or I should seek deeper understanding of the subject?

• "Updating VMware Tools for Linux" spins forever

  - by Nicolas Raoul

  I installed Ubuntu 11.04 inside VMware Player 3.1.4 inside Ubuntu 10.10 When first booting on the ISO image I was asked if I wanted to download the VMware Tools for Linux and I accepted. It downloaded for a few minutes, and then it has been "updating" for an hour already. Even shutting down the VM does not stop it. If I try to exit VMware, I am told "Cannot exit while still downloading. Cancel all downloads and try again." but the dialog's Cancel button is greyed out. Nothing special in vmware.log I ended up killink VMware. A few days after I restarted it, it asked about the VMware Tools again, I accepted again, and same problem...

• Taking Object Oriented development to the next level

  - by Songo

  Can you mention some advanced OO topics or concepts that one should be aware of? I have been a developer for 2 years now and currently aiming for a certain company that requires a web developer with a minimum experience of 3 years. I imagine the interview will have the basic object oriented topics like (Abstraction, Polymorphism, Inheritance, Design patterns, UML, Databases and ORMs, SOLID principles, DRY principle, ...etc) I have these topics covered, but what I'm looking forward to is bringing up topics such as Efferent Coupling, Afferent Coupling, Instability, The law of Demeter, ...etc. Till few days ago I never knew such concepts existed (maybe because I'm a communication engineer basically not a CS graduate.) Can you please recommend some more advanced topics concerning object oriented programming?

• Wobble effects not working on Ubuntu 12.04

  - by Sunny Deere

  Just couple of days before installed Ubuntu 12.04 with all the necessary upgradations. Also installed Compiz Settings Manager & loved the animations & wobble effects of windows. But after restarting windows today, started receiving error messages & Wobble effects are disappeared. Also, other settings created by me in my last login, like small sidebar icons, too disappeared & unable to find even option in "All Settings Appearance" to resize the icons. Loved Ubuntu 12.04, specially Animation & Wobble effects but unhappy with these errors. Thanks in advance.

• With a small development team, how do you organize second-level support?

  - by Lenny222

  Say, you have a team of 5 developers and your inhouse customers demand a reasonable support availability of say 5 days a week, 9am-6pm. I can imagine the following scenarios: the customers approach the same guy, every time. Downside: single point of failure, if the guy is unavailable. each developer is assigned one week of support duty. Downside: how to you distribute the work evenly in times of planned (vacation) and unplanned (sickness) unavailability? each developer is assigned one day of support duty. Downside: similar to above, but not as bad. a randomly picked developer handles the support request. Downside: maybe not fair, see above. What is your experience?

• Ubuntu won't start

  - by Tomas

  I've had Ubuntu installed, using WUBI, for some time now - a few months or so. It's worked fine until now, allowing me to login, use it's features etc... Two days ago, I turned on my computer and started Ubuntu. It loaded the GUI fine but just showed the loading screen and even after waiting 10 mins on this screen it still wouldn't show me the login page. I am enthusiastic about web design and development and all of my work, along with my portfolio is stored in Ubuntu. Cheers, Tomas EDIT: I am using 12.04 LTS.

• How to import in BIDS more than one SSIS package in one shot!

  - by Luca Zavarella

  Have you ever wanted to add more than one Integration Services existing package (e.g. 20 packages) in a SSIS project? Well, you may suppose that an Open Dialog supports multiple files selection to import more than one file at a time ... BIDS Open Dialog doesn’t allow this, you can just select a single file! Hence the loss of valuable time spent to import the packages one at a time. Few days ago I learned a trick that solves the problem, thanks to this post by Matt Masson. Just copy all the packages to import from Windows Explorer (Ctrl + C): Then just right click on the SSIS Packages folder of the Integration Services project and make a simple Past (CTRL + V): So “auto-magically” you’ll have all those packages imported in your Integration Services project!! What can I say... this feature was well hidden!

• How to explain to non-technical person why the task will take much longer then they think?

  - by Mag20

  Almost every developer has to answer questions from business side like: Why is going to take 2 days to add this simple contact form? When developer estimates this task, they may divide it into steps: make some changes to Database optimize DB changes for speed add front end HTML write server side code add validation add client side javascript use unit tests make sure SEO is setup is working implement email confirmation refactor and optimize the code for speed ... These maybe hard to explain to non-technical person, who basically sees the whole task as just putting together some HTML and creating a table to store the data. To them it could be 2 hours MAX. So is there a better way to explain why the estimate is high to non-developer?

• Craftsmanship Tour Day 0: New York

  - by Liam McLennan

  Arriving at JFK, at dawn, is beautiful. From above 1,000ft I can see no crime, poverty or ugliness – just the dark orange sunrise-through-smog. The Atlantic appears calm, and I take that as a good sign. Today is the first day of my software craftsmanship tour. I will be visiting three of the shining lights of the software industry over five days, exchanging ideas and learning. Arriving on the red eye from Seattle I feel like hell. My lips, not used to the dry air, are cracked and bleeding. I get changed in the JFK restroom and make my way from the airport. Following Rik’s directions I take the airtrain to Jamaica. Rik is an engineering manager at Didit in Long Island, the first stop on my tour. From Jamaica I take the Long Island Rail Road train to Rockville Centre, home of Didit.

• Getting work done in a small office

  - by three-cups

  I work in an office area of ~450sqft. There are a total of 7 people working in the office. I've been finding it hard to concentrate on my work (writing code) because of the distractions going on around me. The distractions are both work-related and non-work-related conversations. I'm trying to figure out what to do in this situation. I want to be part of the team, and I want to get my work done to the best of my ability. I can easily think of two options that I don't like: Stay where I am, not be able to concentrate and get less work done Move somewhere else. (This is tough because I code on a desktop, so I'm not very mobile.) But what are other options? I'm going to talk this through with my team in the next couple days. Any advice or solutions would be great.

• I dont know my password and wont let me change it via GRUB

  - by josh

  I recently turned off the login password so i would not have to enter my password every time I turn the system on. But now when I try to update or download anything it asks me for my password so I enter my old password and it keeps telling me its wrong when I have only ever had the 1 password and its a simple 1 so I would not forget and considering I have only had UBUNTU installed for two days it is really frustrating. I have also tried resetting it via the GRUB but it wont let me type the new password. Please help ASAP.

• How do you get aware of new tools?

  - by Konstantin Petrukhnov

  How do you get aware of new tools (libraries, applications, etc)? This question is only about "getting aware" that some tool exist and could be used. Learning and trying is different issue. Right now I get most awareness from stackexchange and freshmeat sites. But I wonder if there are more efficient way. E.g. 80% of freshmeat projects are no-use for me, but it reasonable overhead, because tools that I find trough it save me days or even weeks. Here are some related, but a bit different questions: How much time do you invest in exploring new technology? How to become aware of new languages, techniques and methodologies? What website are you using most to keep you updated on software development?

• How do I get an Acer Aspire One D270 working?

  - by ronnie

  I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

• Code sample after Job offer?

  - by mdominick

  I was verbally offered a job and the manager insisted that I start the day after the following day from the interview; so two days after the interview. I left the interview unsure of the offer the manager called me later that day and I agreed to take the position. At this point, I was told that I would get an offer letter the following day and would start the day after that. Later that evening I was asked for a code sample. I have yet to receive the offer letter the business day is about to close. I've been mostly contracting and usually answer technical questions or show samples at the beginning of the process and find this situation somewhat odd. Is this a common practice? Should I call the manager before business closes?

• Permanent redirect domain to www subdomain without web.config

  - by Lord Simpson

  I've just set up a site via 1and1 and have run into an issue, I want to accomplish the simple task of redirecting the root domain to the www sub domain however due to complications I cant seam to find a way to get it to work. I'm on a Microsoft (asp.net) package so can't use .htaccess, also the IIS server they have doesn't have the URL redirect module installed (so can't use <rewrite> in web.config). They have built in HTTP forwarding options however if I set the root domain to redirect to the www sub domain it just infinitely redirects. Hopefully there is some obvious option/method I've missed during the past two days of searching!

• Programmers that need a lot of "Outside Help" - Is this bad?

  - by Zanneth

  Does anyone else think it's kind of tacky or poor practice when programmers use an unusual amount of libraries/frameworks to accomplish certain tasks? I'm working with someone on a relatively simple programming project involving geolocation queries. The guy seems like an amateur to me. For the server software, this guy used Python, Django, and a bunch of other crazy libraries ("PostGIS + gdal, geoip, and a few other spatial libraries" he writes) to create it. He wrote the entire program in one method (in views.py, nonetheless facepalm), and it's almost unreadable. Is this bad? Does anyone else think that this is really tacky and amateurish? Am I the only minimalist out there these days?

• Share on Facebook does not show thumbnail images

  - by matt_tm

  I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

• no back light on my acer aspire 5734z

  - by Dave

  I installed Ubuntu (12.04) on my acer aspire 5734z and the back light stopped working. I have tried the fix by editing the grub file posted on here a couple of days ago but that hasn't fixed it. I have also looked for hardware drivers but that didn't get me anywhere. When I hook up an external monitor it works fine but i have been unsuccessful getting the laptop display to light up. Thanks edit removed link I found a fix here " http://crunchbanglinux.org/forums/post/66562/#p66562 " if anyone has a better fix than the one in that post, let me know.

• Making organic 2D tilemaps for tile based games...

  - by Codejoy

  So I have always wondered how one makes a nice (not so squarish) 2d tile map, is it possible? all games now days I think use textured polygons...but my game engine (and engine) doesn't support that to my knowledge. But it does support nice TMX files generated by mapeditor.org's Tiled Map Editor. Though in my game I want nice twisting and turning caverns to traverse ... I was wondering some ideas on such a process... is it in the art style? The type of tile engine? both? So what are some common techniques?

• Tempescope Displays Weather by Recreating It

  - by Jason Fitzpatrick

  Yesterday we showed you an umbrella stand that signals raining/clear skies by color, today we have something even more interesting: an ambient desktop weather station that recreates the outside weather. The Tempescope pulls down the current weather report from Weather Underground’s API and feeds it to an Arduino board which in turn controls the device. When it’s raining, it pumps water down to simulate rain in the chamber. When there is lightening, LEDs flash. When there is cloud cover, an ultrasonic generator creates a fine mist inside the cylinder. Finally, on sunny days the entire thing glows warmly. To say that we want one would be an understatement. Hit up the link below to read more about the project, the display modes, and to peek inside the device.
