• List of blogs - year 2010

  - by hajan

  This is the last day of year 2010 and I would like to add links to all blogs I have posted in this year. First, I would like to mention that I started blogging in ASP.NET Community in May / June 2010 and have really enjoyed writing for my favorite technologies, such as: ASP.NET, jQuery/JavaScript, C#, LINQ, Web Services etc. I also had great feedback either through comments on my blogs or in Twitter, Facebook, LinkedIn where I met many new experts just as a result of my blog posts. Thanks to the interesting topics I have in my blog, I became DZone MVB. Here is the list of blogs I made in 2010 in my ASP.NET Community Weblog: (newest to oldest) Great library of ASP.NET videos – Pluralsight!

You may find most of my weblogs.asp.net/hajan blogs posted there too, but there you can find many others. In my blog on MKDOT.NET Community you can find most of my ASP.NET Weblog posts translated in Macedonian language, some of them posted in English and some other blogs that were posted only there. By reading my blogs, I hope you have learnt something new or at least have confirmed your knowledge. And also, if you haven't, I encourage you to start blogging and share your Microsoft Tech. thoughts with all of us...

• How to use an adjacency matrix to determine which rows to 'pass' to a function in r?

  - by dubhousing

  New to R, and I have a long-ish question: I have a shapefile/map, and I'm aiming to calculate a certain index for every polygon in that map, based on attributes of that polygon and each polygon that neighbors it. I have an adjacency matrix -- which I think is the same as a "1st-order queen contiguity weights matrix", although I'm not sure -- that describes which polygons border which other polygons, e.g., POLYID A B C D E A 0 0 1 0 1 B 0 0 1 0 0 C 1 1 0 1 0 D 0 0 1 0 1 E 1 0 0 1 0 The above indicates, for instance, that polygons 'C' and 'E' adjoin polygon 'A'; polygon 'B' adjoins only polygon 'C', etc. The attribute table I have has one polygon per row: POLYID TOT L10K 10_15K 15_20K ... A 500 24 30 77 ... Where TOT, L10K, etc. are the variables I use to calculate an index. There are 525 polygons/rows in my data, so I'd like to use the adjacency matrix to determine which rows' attributes to incorporate into the calculation of the index of interest. For now, I can calculate the index when I subset the rows that correspond to one 'bundle' of neighboring polygons, and then use a loop (if it's of interest, I'm calculating the Centile Gap Index, a measure of local income segregation). E.g., subsetting the 'neighborhood' of the Detroit City Schools: Detroit <- UNSD00[c(142,150,164,221,226,236,295,327,157,177,178,364,233,373,418,424,449,451,487),] Then record the marginal column proportions and a running total: catprops <- vector() for(i in 4:19) { catprops[(i-3)]<-sum(Detroit[,i])/sum(Detroit[,3]) } catprops <- as.data.frame(catprops) catprops[,2]<-cumsum(catprops[,1]) Columns 4:19 are the necessary ones in the attribute table. Then I use the following code to calculate the index -- note that the loop has "i in 1:19" because the Detroit subset has 19 polygons. cgidistsum <- 0 for(i in 1:19) { pranks <- vector() for(j in 4:19) { if (Detroit[i,j]==0) pranks <- append(pranks,0) else if (j == 4) pranks <- append(pranks,seq(0,catprops[1,2],by=catprops[1,2]/Detroit[i,j])) else pranks <- append(pranks,seq(catprops[j-4,2],catprops[j-3,2],by=catprops[j-3,1]/Detroit[i,j])) } distpranks <- vector() distpranks<-abs(pranks-median(pranks)) cgidistsum <- cgidistsum + sum(distpranks) } cgi <- (.25-(cgidistsum/sum(Detroit[,3])))/.25 My apologies if I've provided more information than is necessary. I would really like to exploit the adjacency matrix in order to calculate the CGI for each 'bundle' of these rows. If you happen to know how I could started with this, that would be great. and my apologies for any novice mistakes, I'm new to R!

• How to fix: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

  - by ybbest

  Issue: Recently, I am having issues with deploying asp.net mvc 4 application to Windows Server 2008 R2.After add the necessary role and features and I setup an application in IIS. However , I received the following error message: PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list   Solution: It turns out that this is because ASP.Net was not completely installed with IIS even though I checked that box in the “Add Feature” dialog.   To fix this, I simply ran the following command at the command prompt %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i If I had been on a 32 bit system, it would have looked like the following: %windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe –i   References: http://stackoverflow.com/questions/6846544/how-to-fix-handler-pagehandlerfactory-integrated-has-a-bad-module-managedpip

• list of things to think about for hosting a potentially high traffic website

  - by SpashHit

  I do my own hosting for a few clients on my own VPS server (Lindode). Since my clients so far have been extremely low traffic, I have not had to really dig into some of the considerations that I would need for a higher traffic site. Now I am bidding on a client whose site will be potentially higher (not Facebook or twitter, but higher than Joe's ice cream shop). Is there a list of things I need to think about that I may be missing? I am going to assume, at least at first, that I will be able to handle them on my shared Linode, but I could move to a dedicated Linode if need be. I am not thinking so far of multiple servers, but short of that there are still considerations. For example, mod_perl instead of straight CGI, better backups, etc. What else? In case it matters, the stack will be debian-linux / apache / Perl / mysql / Template Toolkit.

• Update Manager is in Launcher and Alt-Tab list, but I can't switch to it

  - by Jeff

  The Update Manager recently started itself and found two updates. I can tell by the icon in the launcher. The icon has a (2) on it and a little white arrow saying the application is running. I can also see the update-manager process in a 'ps -A' list. Alt-Tab also shows the Update Manager. The problem is I can't get Update Manager to show up. If I click on the icon or Alt-Tab to it, nothing happens. I've never had any issues starting it manually, but when it starts on it's own after finding an update, I can't switch to it. What can I try to make this work better?

• Your interesting code tricks/ conventions? [closed]

  - by Paul

  What interesting conventions, rules, tricks do you use in your code? Preferably some that are not so popular so that the rest of us would find them as novelties. :) Here's some of mine... Input and output parameters This applies to C++ and other languages that have both references and pointers. This is the convention: input parameters are always passed by value or const reference; output parameters are always passed by pointer. This way I'm able to see at a glance, directly from the function call, what parameters might get modified by the function: Inspiration: Old C code int a = 6, b = 7, sum = 0; calculateSum(a, b, &sum); Ordering of headers My typical source file begins like this (see code below). The reason I put the matching header first is because, in case that header is not self-sufficient (I forgot to include some necessary library, or forgot to forward declare some type or function), a compiler error will occur. // Matching header #include "example.h" // Standard libraries #include <string> ... Setter functions Sometimes I find that I need to set multiple properties of an object all at once (like when I just constructed it and I need to initialize it). To reduce the amount of typing and, in some cases, improve readability, I decided to make my setters chainable: Inspiration: Builder pattern class Employee { public: Employee& name(const std::string& name); Employee& salary(double salary); private: std::string name_; double salary_; }; Employee bob; bob.name("William Smith").salary(500.00); Maybe in this particular case it could have been just as well done in the constructor. But for Real WorldTM applications, classes would have lots more fields that should be set to appropriate values and it becomes unmaintainable to do it in the constructor. So what about you? What personal tips and tricks would you like to share?

• Exposing warnings\errors from data objects (that are also list returned)

  - by Oren Schwartz

  I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

• List of Appindicators

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo and unlike 10.10 there is no way to get these on panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

• How to list user installed applications (not packages)?

  - by Bucic

  Not packages and not all applications. Just the applications user installed by himself from whatever source (Software Center, manually added PPA, etc.). If the above is not possible - a list of all installed applications or at least a GUI which lists the applications so I can take screenshots of it. I've read a dozen of similar questions and people posting answers usually don't even get close to OP question merit. Please note that my question includes 'user installed'. Answer: It is not currently possible in Ubuntu Linux. (choosing tijybba's answer as the closest one though)

• joomla 2.5 : list links to articles in 2 columns

  I have a Joomla! 2.5 website, and I have to add a lightbox popup that will contain links to all articles from a specific category(+subs). If anyone can suggest all-in-one solution, that will be great! But generally I'm asking, how to list links to all articles from a specific category and its sub-categories in two/three columns? I know I can set Category blog View to output only article links, without full/introtext, but in this case links will all be in one column. I need at least two. A possibility of grouping article links by subcategory would be great as well (but this is the thing I can live without). How can this be done? I'm looking for: a standard way of configuring this Template override (I'm using T3 framework) Custom extension any other method ...

• Why is a linked list implementation considered linear?

  - by VeeKay

  My apologies for asking such a simple question. Instead of posting such basic question in SO, I felt that this is more apt a question here. I tried finding an answer for this but none of them are logically appealing or convincing to my understanding. Typically, computer memory is always linear. So is the term non linear used for a data structure in a logical sense? If so, to logically achieve non linearity in a linear computer memory, we use pointers. Right? In that case, if pointers are virtual implementations for achieving non linearity, Why would a data structure like linked list be considered linear if in reality the nodes are never physically adjacent?

• Ubuntu 13.04 ERROR: /etc/apt/sources.list not found

  - by Richard Riley

  So, I tried uninstalling the LAMP stack I had following the Ubuntu documentation for it. I also manually removed dbconfig-common. Now, I'm unable to run apt-get update. When I do, I get the error message: E: The method driver /usr/lib/apt/methods/htp could not be found. After some digging, I've discovered that I no longer even have an /etc/apt/sources.list file. Also, I've received an error, when trying to run: sudo tasksel install lamp-server That aptitude can not be found. Does anyone have an idea of what I can do? I'm not able to find any documentation online that works - all the documentation out there is dated and no longer (or will not) work with 13.04. I followed this link previously prior to posting my question and it did not work for me: How do I fix a "E: The method driver /usr/lib/apt/methods/http could not be found." error?

• Best approach to get clicked objects from a display list (2D)

  - by Ixx

  I'm implementing a display list to manage my visuals on screen. I want to know which object is clicked. My objects already have z-order variable. With my current knowledge (almost nothing) the only thing which comes to my mind is make a linear search and get all the objects which contains the clicked point. And then select the object with the highest z-order. But I know there are far better approaches. I think it's something with trees (binary search?). - container display objects and search recursively? just don't know where to start looking, for this concrete case. Any hint link or concrete solution is welcome.

• core.* files eating up server space (~50MB)

  - by skytreader

  I'm renting server space from someone and, upon logging in my control panel after quite sometime, noticed an abnormal spike (~50MB) in the disk usage. Upon investigating, I found a lot of core.* files scattered around my public_html directory. Each one is more than 5MB in size but no more than 6MB. The * part is all numbers (in programming regex, that should be core\.\d+). I downloaded one and checked the contents. There was a lot of balderdash characters (NUL mostly, but also a scattering of ETB, ETX, STX) but there's this block of readable text which says: This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Pretty self-explanatory. A few blocks above the text are some more readable messages that look like logs but is sandwiched in between non printable characters. I've extracted some below. Scan not valid for mh mailboxes Bogus character 0x%x in news state Can't rewrite news state %.80s Error closing backup news state %.80s No state for newsgroup %.80s found Now, a few concerns: Am I under attack? The messages seem to be about my webmail but I don't use my personal webmail that much---only for a vanity email address and an inbox for an outdated comments system. However, lately, I seem to notice a spike in the spam for my vanity mail. (Note: the comments system is covered by a captcha but every now and then some get through. My vanity email has a spam filter but it isn't as good as I'd like). Next, if this is a feature, can I turn it off? Is it advisable to? I've only 150MB so you see why I'm fretting over a 50MB spike. Some final details: my only server-side scripts are in PHP. The directory which accumulated the most number of these core files is the one containing the Wordpress-managed subdomain of my site. I manage my server through CPanel. Lastly, I decided to delete this files and after some checking nothing seems amiss in my websites nor in my mail. They are indeed the ones responsible for the ~50MB spike as my disk space usage is back to expected.
