• My First 5K, the recap.

  - by Chris Williams

  It was a nice day to be outside (and trust me, those aren't words you'll hear from me often.) I got to the site around 7:45, hit the pre-reg table and got my number along with a goody bag full of coupons for racing gear, a water bottle and a tshirt. Oh and a map. Stashed all that stuff in the jeep, emptied my pockets of everything but my iPhone and my jeep key, and proceeded to walk around for a bit as people started showing up and signing in. It was fairly breezy, and there was definitely a storm coming... but it was anyone's guess on when it would actually arrive. It was interesting to see everyone who was participating. If I had to guess, I would say the event was 60-70% women, with a pretty broad distribution of age... as young as 13 to well over 60 (in both genders.) I don't know exactly how many folks were there, but it was well over 300. Eventually it was time to kick things off, and everyone made their way to the start line. All of the 5k and 10k runners were mixed together, starting at the same time. All the walkers and the people with strollers or dogs were in the back. It was pretty chaotic at first, once things started, but it thinned out fairly quickly. The 10k people and the hardcore runners sped ahead of everyone else and the walkers gradually lagged behind. The 5K course was pretty nice, winding around a lake down in Eden Prairie. The 10K course overlapped most of ours, but branched off a couple times too. I didn't run the whole time, but I started the race running and I ended it running, and did a mix of walking and running along the way. I met my goals, which were a) don't ever stop and b) don't be last. The weather managed to hold out for the entire race. It never got too hot, there was a nice breeze and it was mostly overcast. Pretty much perfect in my book. About 20-30 minutes after I left, the rain came down pretty hard. I had a good time, and will most likely do more of them. We'll see.

• How to end a relationship with a client without pissing them off?

  - by thesam18888

  Here's my situation: I'm a freelancing student and I was working on a software project for a client over the summer holidays of 2010. At the time I completed the application, tested it on my machine, delivered it to the client and went back to University. However the client is not completely satisfied with the product and apparently has found a couple of bugs with it. Ever since I went back to Uni, they have been chasing me up and asking me to spend some time to fix the bugs. I have explained that this is simply not possible as I am extremely busy with my Uni work and cannot afford to spare my time for anything else. The client is getting increasingly pissed off and have been chasing me by calling during lectures at evenings and even asking me if I could go over to their place over the weekend to talk about this. This is in turn pissing me off as well because they're essentially asking me to give up my education so that I could help them out by fixing bugs. I go to Uni 5 days a week, 9-6 and feel it is unreasonable for them to call me during evenings and to ask me to work over weekends etc. I would like to end my relationship with this client but would like to do it amicably without pissing them off. How can I do this? I really wish they would just find someone else but I was charging them piss-poor rates so I think they don't want to go to anyone else because they would have to pay more. EDIT The application does not seem to work perfectly on their machine. I had tested it extensively on my machine and it seemed to work fine. I am not sure what exactly is causing it to not work. I was paid a very low amount and it was on an hourly basis. e.g. I would send an invoice saying I worked on this for x amount of hours and they would pay me for it. Apart from the work itself, I have not charged them for all the time spent sending e-mails back and forth, phone calls, visits to their place etc. I would really like to end all my dealings with this client right away.

• Why is learning assembly language seen as a disadvantage?

  - by cprogcr

  I was recently reading an article about making a compiler, and one of the disadvantages mentioned about making a compiler instead of interpreter, was "Learning Assembly language".I understand that perhaps it takes a little more time to learn ASM than it would take for a high level language. But why should it be seen as a disadvantage? And this is not the first time, I mean there are a lot of articles which see ASM as a disadvantage or not important.Personally I find ASM interesting and not at all as a "disadvantage".

• How do I change the date format in Gnome 3 shell?

  - by James Haigh

  I want to change the date/time format on the top panel to a format close to RFC 3339 / ISO 8601, like one of these: %F %T ? 2013-06-24 16:13:00 %F %a %T ? 2013-06-24 Mon 16:13:00 %A %F %T ? Monday 2013-06-24 16:13:00 I know Unity has a preference somewhere hidden away in dconf, this is how I did it in Unity, but I can't find such a preference for Gnome 3 shell. Preferably, I'd also like to set one of these as my system-wide date/time locale preference.

• Why the static data members have to be defined outside the class separately in C++ (unlike Java)?

  - by iammilind

  class A { static int foo () {} // ok static int x; // <--- needed to be defined separately in .cpp file }; I don't see a need of having A::x defined separately in a .cpp file (or same file for templates). Why can't be A::x declared and defined at the same time? Has it been forbidden for historical reasons? My main question is, will it affect any functionality if static data members were declared/defined at the same time (same as Java) ?

• Oredev 2012: Summary and source code

  - by Laurent Bugnion

  This week, I had the pleasure to be invited to talk at Oredev, a really cool conference taking place in Malmo, Sweden. The whole event is awesome, including a very special dinner on Monday including sauna and swimming in a 6 degrees cold Baltic sea, and a reception with dinner at the town hall, including the mayor himself. Considering Malmo is a town of 300'000 inhabitants, it is a pretty nice occasion and the historical building itself is really worth seeing. For those interested, I placed my pictures on my Flickr account. I had a workshop on Tuesday morning about Windows 8 development with XAML/C#, and then a session on Wednesday about MVVM in Windows Phone 8 and Windows 8, of course using MVVM Light. I was very nervous because I reworked some of my demos as recently as this morning, in the wake of the Build conference last week and the release of both the Windows Phone SDK and MVVM Light V4.1. Everything went well however, and if I judge by the people I talked t after the talk, and Twitter, everything went pretty well. Before my talk on Tuesday, I had the pleasure to see a talk by Iris Classon (@irisclasson) on the challenges of being a "n00b" and a woman in software development. I especially appreciated her research and conclusions on the lack of women I our industry, a topic that is dear to my heart (because I want the best possible future for my two daughters, and also because I really enjoy working with women on projects, and getting a different insight on the art of software development. I really want to thank the excellent organization committee for their hard work and their fantastic welcome to Malmo. In particular Emily Holweck did a wonderful job and was super helpful throughout the preparation and the conference itself. I made a few pictures during my stay, all with the new Nokia Lumia 920, and hope you will enjoy them too. The source code and the slides… The source code is available for download from Skydrive. You will find the following: Windows 8 workshop slides. MVVM Applied slides Source code package with Win8Demo: The demo I built during the 4 hours workshop, with some light MVVM, web services (JSON), GridView, Design time data (Blend / Visual Studio designer), Bing maps integration, location sensor, Search pane integration. SemanticZoomSample: a sample I put together to demonstrate the SemanticZoom control, with two GridViews and of course full design time data for Blend work. Due to time constraints, I was not able to show this demo during the workshop, but I publish it anyway, hoping it will be useful to someone. PictureUploader: The demo I built during my 50 minutes session about MVVM Applied in Windows Phone 8 and Windows 8. Code sharing, design time data, MVVM Light are used in Windows Phone 8 and Windows 8 apps. And in video… You can also see the video of my MVVM talk thanks to the good services of the Oredev team!

• After Re-opening Laptop, Programs Blink with Each Keystroke, Ubuntu 12.04, Dell Latitude D620

  - by Calhan

  I'm running Ubuntu version 12.04 on Dell D620 laptop and have been for months. Everything has been working fine until a week ago, when suddenly every time I close the laptop and open it again, the program in use blinks each time I make a keystroke. Only the program blinks, not the whole screen. Rebooting solves the issue until I close the lid again. I have installed all the updates recommended in the package manager. Clues?

• What is the proper SEO way to add and remove links to our site and sitemap?

  - by ElHaix

  As content fluctuates on our site, we will obviously add the titles to the new pages to our sitemap, and link list for search engine indexing. Through time, certain links will become less relevant, and would like to know how to avoid them being crawled. The links themselves may not be removed - but we don't want to dilute the link list with less relevant links as time passes. I'm guessing the status code of the page would change - to what? Should they also removed from the sitemap?

• I am not able to disable certain keys even after using xmodmap

  Some of the keys on my keyboard are continously pressed. I am trying to disable that key using the following command: xmodmap -e 'keycode 115=' or xmodmap -e 'keycode 115='NoSymbol' It works for some time, I can see the Symbol associated with that key getting updated using xev command. But the problem is it gets changed to it's default symbol after some time and starts creating the problem again. How can I overcome this issue.

• Will we see a trend of "3d" games coming up in the near future?

  - by Vish

  I've noticed that the trend of movies is diving into the world of movies with 3-dimensional camera.For me it provoked a thought as if it was the same feeling people got when they saw a colour movie for the first time, like in the transition from black and white to colour it is a whole new experience. For the first time we are experiencing the Z(depth) factor and I really mean when I said "experiencing". So my question is or maybe if not a question, but Is there a possibility of a genre of 3d camera games upcoming?

• Should I continue to pursue programming based on my experience?

  - by El Be

  The reason I ask this question is because I am not sure my troubles come from a lack of confidence, or something much deeper like lack of passion. I'm hoping experienced programmers and developers can help identify the cause of my troubles. To be brief my undergraduate major was in Computer Science, but in a small school and I had the highest gpa in my year in computer science. The first time I ever programmed was once in the 5th grade (using logo) and when I was a freshman in college. I enjoyed programming when I was in school. Then I did an internships where I was expected to produce image processing software and program microchips. I was unsuccessful and produced little results and I hated the job, because I had to figure out everything for myself, did not have any help, and there was a lot of pressure to produce results. Although I tried I could not figure out what to do and was stuck all the time and made me dislike the job. When the internship ended I went to a PhD program for computer science at a prestigious computer science school. I had a very hard time with the course, met people who have been programming since they were 6 and made plenty of applications in their spare time (which I never did, although I tried). I even met many sophomores who understood more than I did. The combination of this and other things have made me feel that programming is not for me, but sometimes I consider a career in programming. I still consider programming as a career because of the career potential (not only just because of money). Based on my experience do you believe my confidence has just been shaken and I should continue to prepare for a programming career, or do you see a lack of passion and it would make it tough to continue programming. thank you for reading and for your advice Thank you for everyone's advice so far! Also: I dropped out of the ph.D program for computer science and switched to a master's in computer graphics. Its more applied, but I still find it hard to be motivated (due to either lack of confidence or passion), but since programming is such a big field I am looking for that niche area that I feel good programming in.

• How to cleanly add after-the-fact commits from the same feature into git tree

  - by Dennis

  I am one of two developers on a system. I make most of the commits at this time period. My current git workflow is as such: there is master branch only (no develop/release) I make a new branch when I want to do a feature, do lots of commits, and then when I'm done, I merge that branch back into master, and usually push it to remote. ...except, I am usually not done. I often come back to alter one thing or another and every time I think it is done, but it can be 3-4 commits before I am really done and move onto something else. Problem The problem I have now is that .. my feature branch tree is merged and pushed into master and remote master, and then I realize that I am not really done with that feature, as in I have finishing touches I want to add, where finishing touches may be cosmetic only, or may be significant, but they still belong to that one feature I just worked on. What I do now Currently, when I have extra after-the-fact commits like this, I solve this problem by rolling back my merge, and re-merging my feature branch into master with my new commits, and I do that so that git tree looks clean. One clean feature branch branched out of master and merged back into it. I then push --force my changes to origin, since my origin doesn't see much traffic at the moment, so I can almost count that things will be safe, or I can even talk to other dev if I have to coordinate. But I know it is not a good way to do this in general, as it rewrites what others may have already pulled, causing potential issues. And it did happen even with my dev, where git had to do an extra weird merge when our trees diverged. Other ways to solve this which I deem to be not so great Next best way is to just make those extra commits to the master branch directly, be it fast-forward merge, or not. It doesn't make the tree look as pretty as in my current way I'm solving this, but then it's not rewriting history. Yet another way is to wait. Maybe wait 24 hours and not push things to origin. That way I can rewrite things as I see fit. The con of this approach is time wasted waiting, when people may be waiting for a fix now. Yet another way is to make a "new" feature branch every time I realize I need to fix something extra. I may end up with things like feature-branch feature-branch-html-fix, feature-branch-checkbox-fix, and so on, kind of polluting the git tree somewhat. Is there a way to manage what I am trying to do without the drawbacks I described? I'm going for clean-looking history here, but maybe I need to drop this goal, if technically it is not a possibility.

• How far should an entity take care of its properties values by itself?

  - by Kharlos Dominguez

  Let's consider the following example of a class, which is an entity that I'm using through Entity Framework. - InvoiceHeader - BilledAmount (property, decimal) - PaidAmount (property, decimal) - Balance (property, decimal) I'm trying to find the best approach to keep Balance updated, based on the values of the two other properties (BilledAmount and PaidAmount). I'm torn between two practices here: Updating the balance amount every time BilledAmount and PaidAmount are updated (through their setters) Having a UpdateBalance() method that the callers would run on the object when appropriate. I am aware that I can just calculate the Balance in its getter. However, it isn't really possible because this is an entity field that needs to be saved back to the database, where it has an actual column, and where the calculated amount should be persisted to. My other worry about the automatically updating approach is that the calculated values might be a little bit different from what was originally saved to the database, due to rounding values (an older version of the software, was using floats, but now decimals). So, loading, let's say 2000 entities from the database could change their status and make the ORM believe that they have changed and be persisted back to the database the next time the SaveChanges() method is called on the context. It would trigger a mass of updates that I am not really interested in, or could cause problems, if the calculation methods changed (the entities fetched would lose their old values to be replaced by freshly recalculated ones, simply by being loaded). Then, let's take the example even further. Each invoice has some related invoice details, which also have BilledAmount, PaidAmount and Balance (I'm simplifying my actual business case for the sake of the example, so let's assume the customer can pay each item of the invoice separately rather than as a whole). If we consider the entity should take care of itself, any change of the child details should cause the Invoice totals to change as well. In a fully automated approach, a simple implementation would be looping through each detail of the invoice to recalculate the header totals, every time one the property changes. It probably would be fine for just a record, but if a lot of entities were fetched at once, it could create a significant overhead, as it would perform this process every time a new invoice detail record is fetched. Possibly worse, if the details are not already loaded, it could cause the ORM to lazy-load them, just to recalculate the balances. So far, I went with the Update() method-way, mainly for the reasons I explained above, but I wonder if it was right. I'm noticing I have to keep calling these methods quite often and at different places in my code and it is potential source of bugs. It also has a detrimental effect on data-binding because when the properties of the detail or header changes, the other properties are left out of date and the method has no way to be called. What is the recommended approach in this case?

• Should the test and the fix be written by different people?

  - by Nutel

  There is a common practice in TDD to write a test before fix to avoid regression and simplify fixing. I just wonder what if the test and fix will be written by different people, total spent time will be almost the same but as now three people will think about possible failures (+tester) we increase probability that fix will cover all possible failure scenarios. Does this practice make sense or it will just waste additional time needed for one more person to familiarize with bug?
