• Ubuntu 12.04 stopped recognizing my BenQ monitor and reduced resolution to 1024x768

  - by Omri

  A few days ago I installed Ubuntu 12.04 32bit Desktop. It recognized my hardware without a problem (at least that I know of) and all worked fine. I left my system running (it is at work) through the night because it is also working as a database server and when I came today to work the resolution was 1024x768 (the monitor recommends 1920x1080) even though in the Display section of the System Settings it was recognized as BenQ, and no higher resolution was offered. After a restart, the monitor name changed from BenQ to Unknown. This is a desktop computer. I also installed gtk-redshift and f.lux. I checked Additional Drivers to see if there is something I can install but it didn't find anything. I tried to Google it but I didn't find anything about a monitor stopping being recognized after it was already working. I did enable some PPAs yesterday, namely webupd8, mozillateam/thunderbird-stable and some other, and I also followed the instructions to patch the NotifyOSD to be more friendly: sudo add-apt-repository ppa:caffeine-developers/ppa sudo add-apt-repository ppa:leolik/leolik sudo apt-get update sudo apt-get upgrade sudo apt-get install libnotify-bin pkill notify-osd sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install notifyosdconfig I now purged both caffeine-developers and leolik PPAs in the hope it will help, but no change. Has there been a change in the packages that could introduce this problem? Any help will be very appreciated :-) Omri

• What's the best way to learn/increase problem-solving skills?

  - by tucaz

  Hi all! I'm not sure this is the right place to ask this question, neither if this is the right way to ask this question but I hope you help me if it is not. I work as a programmer since I was 15 (will be 24 next week) so learning programming logic was somehow natural during the course of my career and I think that it helped me to get pretty good problem-solving. One thing none of us (programmers) can deny is that programming logic helps us in a lot of fields outside computer programming. So I'd say it is a very valuable resource that one should learn. My girlfriend is not a programmer and graduated in college on a non related course (Foreign Relations) because she didn't know what to study back then. As the years passed she discovered that she liked Logistics and started to work with it almost two years ago. However, since she does not have a technical background (not even basic Math) she is really having a hard time with it. She is already trying to catch up with Math, but even simple questions/brain-teasers are hard to her. For example, trying to find the missing numbers of this sequence: 0, 1, 1, 2, 3, 5, 8, _, _, 34 and so on. We know that this is Fibonacci but if we didn't we would probably be able to get to the correct answer just by "guessing" (using our acquired problem-solving skills). I'm not sure if problem-solving skills or logic are the correct name for it, but this is what I mean: quick solve problems, brain-teasers, find patterns, have a "sharp" mind. So, the question is: what is the best way for someone to learn this kind of skills without being a programmer (or studying algorithms and such)? If you say it is a book, could you please recommend one? Thanks a lot!

• What is the best approach to solve a factory method problem which has to be an instance?

  - by Iago

  I have to add new funcionality in a web service legacy project and I'm thinking what is the best approach for a concrete situation. The web service is simple: It receives a XML file, unmarshalling, generates response's objects, marshalling and finally it sends the response as a XML file. For every XML files received, the web service always responds with the same XML structure. What I have to do is to generate a different XML file according to the XML received. So I have a controller class which has all marshalling/unmarshalling operations, but this controller class has to be an instance. Depending on XML received I need some marshalling methods or others. Trying to make few changes on legacy source, what is the best approach? My first approach was to do a factory method pattern with the controller class, but this class has to be an instance. I want to keep, as far as it goes, this structure: classController.doMarshalling(); I think this one is a bit smelly: if(XMLReceived.isTypeOne()) classController.doMarshallingOne(); else if(XMLReceived.isTypeTwo()) classController.doMarshallingTwo(); else if(XMLReceived.isTypeThree()) classController.doMarshallingThree(); else if ... I hope my question is well understood

• Is there value in having new developers (graduates) start as testers / bug-fixers?

  - by Nico Huysamen

  Hi Programmers Community. What are your thoughts on the following: Is there value in having new developers (graduates) start as testers / bug-fixers? There are two schools of thought here that I have come across. Having new developers (graduates) start as testers / bug-fixers / doing SLA (Service Level Agreement) work, get's them familiar with the code base. It also allows them the opportunity to learn how to read [other people's] code. Further more, by fixing bugs, they will learn certain bad and good practices, which could hopefully help them in the future. The other way of thinking though, is that if you immediately start new developers on something like testing / bug-fixing / SLA work, their appetite for the development world might go away, and/or they might leave the company and you potentially loose out on a great future resource. Is there a balance that should be kept between these two? Currently where I work there is no clear-cut definition of what new starters do. Some go directly on to client work, while some fall in to the SLA world. Should companies have such a policy? Or should it be handled on a case-by-case or opportunity-based basis? Hope to hear from some of you that have experience in this field. Thanks!

• A short but intense GCC Gathering in London

  - by user817571

  About one week ago I joined in London many long time GCC friends and acquaintances for a gathering organized by Google (in particular I guess should be thanked Diego and Ian). Only a weekend, and I wasn't able to attend on Sunday morning, but a very good occasion to raise some issues in a very relaxed way, in particular those at the border between areas of competence, which are the most difficult to discuss during the normal work days. If you are interested in a general overview and some notes this is a good link: http://gcc.gnu.org/wiki/GCCGathering2011 As you may easily guess, the third topic is mine, which I managed to have up quite early on Friday morning thanks to the votes of some good friends like Dodji (the ordering of the topics resulted from democratic voting on Friday evening!). I learned a lot from the discussion: for example that certainly the new C++11 'final' should be exploited largely in the c++ front-end; the various reasons why devirtualization can be quite trick (but I'm really confident that Martin and Honza are going to make a good progress also basing on a set of short testcases which I promised to collect); that, as explained by Ian, the gold linker already implements the nice --icf (Identical Code Folding) facility, which some friends of mine are definitely going to like (however, see: http://sourceware.org/bugzilla/show_bug.cgi?id=12919). I also enjoyed the observations made by Lawrence, where he remarked that in C+11 we are going to see more pointer iterations implicitly produced by the new range-based for-loop and we really want to make sure the loop optimizers are able to deal with those as well as loops explicitly using a counter. All in all, I really hope we are going to do it again!

• Two new profile in new visual studio 2010.

  - by Jalpesh P. Vadgama

  Visual studio 2010 is a great tool and i have become fan of visual studio 2010. I have found two new code profile in visual studio 2010. Web Development Profile Web Development Code Optimized Profile. Web Development profile will hide the top bar which contains the client object and and event dropdowns. So it will have more spaces. Another one web development code optimized which will hide all the things except main windows. It will hide Toolbox,CSS properties and all other things so you will have more spaces to play with your html. So as a web developer you can use this two great new profile as per your convenience when you only want to play with your html then use webdevelopement code  optimized profile and another interesting thing is that you don’t have to reset your settings you can also just do with Tools->Settings menu like below. This will swap different profile like below. Hope this will help you.. Technorati Tags: Visual Studio 2010,ASP.NET 4.0

• Do you think Scala will be the dominant JVM langauge, ie be the next Java? [on hold]

  - by user1037729

  From what I've read about Scala do far I think it has some nice features but I do not think it should be "the next Java". It might however end up being the next Java (due to fashion rather than fact) but lets not hope it does not... To me adds a lot of complexity over Java which is a simple and scalable language. Scala Pattern matching allows you to perform some type/value checking in a more concise way, this is possible in Java, Scala's pattern matching has a limit to it, you cannot continuously match deeper and deeper down the object graph, so why not just stick to Java and use decent invariants? Scala provides tuples, easy enough to make in Java, create a static factory method and it all reads nicely too. Scala provides mixins, why not just use composition? I believe Scala implicit's are bad, they can lead to code becoming complex and hard to maintain, explicitness is good. Scala provides closures, well they will be in Java 8 too. Scala has lazy keyword for lazy instantiation, this is easy enough to do in Java by calling a getter which creates the instance when needed, no hidden magic here. Scala can be used with AKKA, well so can Java, there is an Java AKKA implementation. Scala offers addition functional features but these can all be created in Java, there are many frameworks with have implemented functional features in Java. All in all Scala seems to offer is addition complexity and thats it...

• Lack of PHP experience = reduced compensation?

  - by Jake Tacholsavacky

  I interviewed for a C++ position at this company, and while they say that I knocked my interview out of the park, they also say that I am too senior for the position. Instead they would like to offer me a job programming in PHP. Unfortunately my PHP experience is limited. Because of this, they are expecting me to take a significant drop in salary with the hope that I will master PHP within a year and be promoted at my first annual performance review. I don't believe that this is reasonable. I agree with Joel when he writes, "Don’t look for experience with particular technologies." If they thought I was such a superstar, then they should have realized that I am capable of being productive in PHP within weeks, not a year! It seems like just an excuse to underpay me. Notwithstanding the fact that I was insulted by this offer, I think that I would be taking on much more risk than they would be; they won't guarantee what my post-PHP salary would be. What does the Stack Exchange community think about this offer? Would you take it?

• Why does running this program on 11.10 give a 'GLIBC_2.15 not found' error?

  - by RafLance

  I am trying to install Absinthe 2.0.4 on Ubuntu 11.10 on a netbook. When I try to run the install file, this keeps on happening: rafael@RafLaptop:~/Desktop/absinthe-linux-2.0.4$ ./absinthe.x86 ./absinthe.x86: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./absinthe.x86) Do I need to upgrade GLIBC? If so, how do I do that? Since I'm on a netbook I can't use a LiveCD so I wanted to know if there was a way I could fix this issue without reinstalling my whole OS. Any explanations about what GLIBC is exactly would be great too since this is a learning experience for me. I know that GLIBC is a part of libc.so.6 and so I tried to run sudo apt-get install libc.so.6 but was told that it was up to date. But GLIBC isn't? I hope this articulates my problem well, if there are any pieces of missing info or questions to clarity my question, please let me know! ~-~ EDIT/UPDATE: So after some help on the AskUbuntu chat room from user izx, I have gathered the following information/understanding: -I need to run this program with Ubuntu 12.04 or recompile it from source -Upgrading libc on Oneiric to 2.15 while possible, is not an easy task and is not officially supported.

• The remote server returned an error: 227 Entering Passive Mode

  - by hmloo

  Today while uploading file to FTP sever, the codes throw an error - "The remote server returned an error: 227 Entering Passive Mode", after research, I got some knowledge in FTP working principle. FTP may run in active or passive mode, which determines how the data connection is established. Active mode: command connection: client >1024  -> server 21 data connection:    client >1024  <-  server 20 passive mode: command connection: client > 1024 -> server 21 data connection:    client > 1024 <- server > 1024 In active mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the client will use PORT command to tell the server:"hi, I opened port XXXX, please connect to me." and then server will use port 20 to initiate the data connection to that client port number. In passive mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the sever will tell the client:"hi, I opened port XXXX , please connect to me." and then client will initiate the data connection to that sever port number. In a nutshell, active mode is used to have the server connect to the client, and passive mode is used to have the client connect to the server. So if your FTP server is configured to work in active mode only or the firewalls between your client and the server are blocking the data port range, then you will get error message, to fix this issue, just set System.Net.FtpWebRequest property UsePassive = false. Hope this helps! Thanks for reading!

• Logistics of code reuse (OOP)

  - by Ominus

  One of the driving points behind OOP is code reuse. I am curious about the actual logistics of this and how others both in team or solo handle it. For example lets say you have 5 projects you have worked on and between them you have a ton of classes that you think would be useful in other projects. How do you store them? Are they just in the normal project repository or do you break out the relevant classes and have them (as now copies) in another unique source repository that only houses code pieces that are intended to be reused? How do you go about finding or even knowing that there is a good piece of code out there that you should reuse? It's easier if your solo because you remember that you have coded something similar but even then it becomes kind of a stretch. If there is some way that you are storing these pieces of code do you then also have them indexed and searchable by tag or something. I fear that it just boils down to some tribal knowledge that you just know that for situation A i need solution B and we have a good piece of code that already can help here. A bit verbose but I hope you get what I am aiming at. If you think of a better way to make the question clearer please have at it :) TIA!

• SSAS Compare version 1.0 released

  - by Red Gate Software BI Tools Team

  We’re pleased to announce that SSAS Compare version 1.0 has been released as a free tool. Version 1.0 includes: Comparisons of live databases and XMLA or Analysis Services Project files MDX syntax diffs and highlighting Server comparisons Deployment wizard with summaries of scripted actions Bug fixes and engine and UI refinements We’ve tested it on as many cube configurations as we could find (not just good old AdventureWorks!), but we can’t provide support for free tools — so if you’re reliant on SSAS Compare for your cube deployment, use it at your own risk. See the user license agreement in the installer for more details. SSAS Compare’s come a long way from its humble beginnings as an internal tool first developed for Red Gate’s own BI developers. Today’s SSAS Compare is now much more stable — not to mention much easier to use — and something the team is proud to have released with Red Gate’s name on. Next: Deployment Manager We’re working on integrating SSAS Compare cube deployment with our new Deployment Manager tool, so you’ll be able to create cube deployment scripts and automate the deployment process, too.  We’re documenting the process in a white paper we’ll publish online in the next week. Thank you! Thanks to all the SSAS Compare users out there. Without your feedback, we could never have produced such a stable product so quickly. We hope you continue to find useful. See you in Deployment Manager!

• Hibernation to a swap file 12.04, fragfile output

  - by MrHug10

  I've been trying for some time now, to get hibernation working in Ubuntu 12.04 on my Dell XPS17. I dualboot Windows 7 and Ubuntu, each having their own partition and one shared partition for all my data and documents. As I would like to be able to swtich from ubuntu to windows without losing all the things I was currently doing in Ubuntu, I would like to be able to use hibernation. In order to achieve this I've followed the information at http://ubuntuforums.org/showthread.php?t=1042946. Only instead of creating my swap file on my linux partition (which is formatted: ext4), I've chosen to create one on my shared partition (which is formatted: ntfs). There is a problem with this though (at least, that's what I think the problem is), because when I call: sudo filefrag -v /media/data/Ubuntu_Swap_Space/6GiB.swap, I get the following output: Filesystem type is: 65735546 File size of /media/Data/Ubuntu_Swap_Space/6GiB.swap is 6442450944 (1572864 blocks, blocksize 4096) Discontinuity: Block 22 is at 25829097 (was 232498) /media/Data/Ubuntu_Swap_Space/6GiB.swap: 2 extents found So I'm not sure what I need to fill in as an offset to follow the rest of the earlier mentioned information. I've tried both the location of block 22 and the number that is listed after that, but when I then try sudo pm-hibernate nothing happens and this shows up in my /var/log/pm-suspend.log s2disk: Could not use the resume device (try swapon -a). Reason: No such device Hope someone can help me out with this! If you need more information about anything, please let me know!

• Advice on software infrastructure for a FLOSS bounty site

  - by michaeljt

  I am planning to set up a simple web site where people can offer bounties for work on FLOSS projects. Unfortunately I have no experience at web development (I am a C/C++ developer), so I was hoping someone might be able to suggest out-of-the-box packages (preferably Debian ones) I could use to build the site from. My idea of how the site would work is to keep things as simple as possible. The person proposing a bounty would enter a description with relevant links (particularly to a bugtracker entry with the project the work is to be done on, where the real discussion and work would take place) and information and place an initial contribution. Other people would be able to add (donate, not pledge) contributions, but any discussion would take place on the project's bugtracker. I am also planning to run a mailing list rather than a forum (at least initially), so that is not a requirement. Paypal seems to me to be the handiest payment mechanism. So overall what I need is probably a simple interface with Paypal integration and a simple database backend. I hope this is the right place for my question, if not I would be grateful for pointers to somewhere better. And of course, this is purely about the technical side, though I am more than happy to discuss other aspects of the project elsewhere.

• about freelancer in third world countries

  - by MaKo

  hello guys, one question that is been bogging me... first of all I want to say that I actually come from a third world country, so I am all up for opportunities for everybody... so here comes my consideration,,, I have been working as a programmer for Iphone apps (noob in the company), now in my new "first" world country (immigration can be good!!!), but seem to be getting more and more advertisement from sites like freelancer.com etc,,, so I would want to know what do you think about all this???, would the jobs be getting cheaper?? if a project can be done by say 10% of the cost overseas, what is stopping the employers of doing just that? is it worth it? how about the quality? from a local job and overseas job? and all other aspects I cannot think about?? I just want to know if all this years of learning are going to pay off? or if in a near future all programming jobs will just go to cheaper labor? (sweat shops??) ok hope to make sense in my ramblings,, cheers;)

• How to procedurally (create) grow an artistic (2D) tree in real-time (L-System?).

  - by lalan

  Recently I programmed an L-system module, It got me interested further. I am a Plants vs Zombies junkie as well, really liked the concept of Tree of Wisdom. Would love to create similar procedural art just for fun and learn more. Question: How should I approach the process of creating an artistic tree (2d perhaps with fixed camera/perspective) dynamically? Ideally I would like to start with a plant (only a stem with a leaf) and grow it dynamically using some influence (input/user action) over its structure. These influences may result in different type of branching, curves in branches, its spread, location of fruits, color of flowers, etc. Want it to be really full of life/spirit. :) Plants vs Zombies: Tree of wisdom It would be great to dynamically grow a similar tree, but with lot more variation and animations happening. My Background: Student / Programmer, have used few game engines (Ogre3d, cocos2d, unity). Haven't really programmed directly using openGL, trying to fix that :). I am ready to spend considerable time, Please let me know about the APIs? and how would an expert like you would take on this problem? Why 2D? I think it's easier to solve the problem only considering 2 dimensions. Artistic inspirations: Only the tree, with fruits and leaves, without the shrubs at the bottom The large tree (visible branches, green leaves, flowers, fruits, etc) on the left, behind monkey. PixelJunk's Eden (Art style inspiration). Procedurally Generated Apple Tree using Fractals Please let me know if it was easy for you to understand the question, I may elaborate further. I hope a discussion of various approach would be helpful for everyone. You guys are awesome.

• Finding a mentor online [closed]

  - by Athena Santos

  Possible Duplicate: How to find programming mentor? I'm a programming intern, but I want to "transition" into a product manager role after graduation. I just know that I will never be a super A++ Rockstar programmer, but from my internship I know that I can be a great program manager..one of those presumably rare people who can code well (enough)/speak programmer-ese and management-ese. Being a girl, I am looking for both male and female mentors. Female, because they know what its like to be a minority, and male, because..well, you guys are tough, and I believe to succeed in tech, a girl's gotta know how to act like a man (when appropriate). I've found some really amazing people I'd like to ask to be my mentor (in blogs, magazines, etc), but sadly, I live far, far away from them. Will be awkward/rude if I shoot them an email about being a mentor? What is the best way to establish a relationship with people like these that I admire? Any volunteers? :) Thank you in advance, and I hope you all have a great day/night.

• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

• https:// search results appearing on Google for purely http:// site

  - by hydrurga

  I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

• MVC Scaffold Template Not Generating?

  - by monkey9987

  Been working on an MVC project and my templates were not generating. I first created my Model inside my "Models" folder, then did a quick compile. Next I went to the Views folder to get it created, right click and say "Add View" then I clicked the checkbox to create an edit page. What happened was the template would never seem to pull in my Model, it would just have the default header items, but the entire model was missing.  My model was defined as follows: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName;[Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password;[Display(Name = "Remember me?")]public bool RememberMe; } See anything wrong with that? I couldn't figure out why each time I created my View and selected the option to create the "Edit" scaffold automatically, it would come up blank. Turns out I'm missing my get / set methods on the Model class items. Here's my code with the correct setup: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName { get; set; } [Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password { get; set; }[Display(Name = "Remember me?")]public bool RememberMe { get; set; } }  I hope that helps someone out, it's pretty simple when I look at it now, but that's always the case!  ~ Steve

• How can I get cross-browser consistent behavior for TR heights within a table with a set height? [migrated]

  I have an arbitrary number of tables with an arbitrary number of rows in each, and all tables are the same height. My initial approach was to just set the overall height of the table and hope the rows were smart enough to distribute themselves appropriately. That's not the case. I have 4 different behaviors going on with 4 browsers, but I need them to all render at the very least in a similar way. Safari & Chrome (WebKit): All rows are equal height, creating scroll bars as needed and fitting within table height. Firefox: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Additionally, If the content of the rows does not take up all of the height, only the part of the table with content in it takes the background (though it seems, through use of Firebug, that the actual table [and TR] extend to the bottom of the proper table height). IE: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Obviously this only includes one version of each browser and additional variation would likely appear with more being tested. Ideally, a solution where the browser renders TRs with less content smaller than those with larger content, while still using scrolling within the variable height TRs when the overall height of the table is not enough would be optimum. I could potentially see a solution to achieve that with JS, but can it be done with CSS? Or, if not, can the behavior that WebKit displays be made to work across the browsers? Thanks! PS: Example can be found here.

• LiveMeeting VC PowerShell PASS – Troubleshooting SQL Server with PowerShell

  - by Laerte Junior

  Guys, join me on Wednesday July 18th 12 noon EDT (GMT -4) for a presentation called Troubleshooting SQL Server With PowerShell. It will be in English, so please make allowances for this. I’m sure that you’re aware that my English is not perfect, but it is not so bad. I will do my best, you can be sure. The registration link will be available soon from PowerShell.sqlpass.org, so I hope to see you there. It will be a session without slides. Just code; pure PowerShell code. Trust me, We will see a lot of COOL stuff.Big thanks to Aaron Nelson (@sqlvariant) for the opportunity! Here are some more details about the presentation: “Troubleshooting SQL Server with PowerShell – The Next Level’ It is normal for us to have to face poorly performing queries or even complete failure in our SQL server environments. This can happen for a variety of reasons including poor Database Designs, hardware failure, improperly-configured systems and OS Updates applied without testing. As Database Administrators, we need to take precaution to minimize the impact of these problems when they occur, and so we need the tools and methodology required to identify and solve issues quickly. In this Session we will use PowerShell to explore some common troubleshooting techniques used in our day-to-day work as s DBA. This will include a variety of such activities including Gathering Performance Counters in several servers at the same time using background jobs, identifying Blocked Sessions and Reading & filtering the SQL Error Log even if the Instance is offline The approach will be using some advanced PowerShell techniques that allow us to scale the code for multiple servers and run the data collection in asynchronous mode.

• A Star Path finding endless loop

  - by PoeHaH

  I have implemented A* algorithm. Sometimes it works, sometimes it doesn't, and it goes through an endless loop. After days of debugging and googling, I hope you can come to the rescue. This is my code: The algorythm: public ArrayList<Coordinate> findClosestPathTo(Coordinate start, Coordinate goal) { ArrayList<Coordinate> closed = new ArrayList<Coordinate>(); ArrayList<Coordinate> open = new ArrayList<Coordinate>(); ArrayList<Coordinate> travelpath = new ArrayList<Coordinate>(); open.add(start); while(open.size()>0) { Coordinate current = searchCoordinateWithLowestF(open); if(current.equals(goal)) { return travelpath; } travelpath.add(current); open.remove(current); closed.add(current); ArrayList<Coordinate> neighbors = current.calculateCoordAdjacencies(true, rowbound, colbound); for(Coordinate n:neighbors) { if(closed.contains(n) || map.isWalkeable(n)) { continue; } int gScore = current.getGvalue() + 1; boolean gScoreIsBest = false; if(!open.contains(n)) { gScoreIsBest = true; n.setHvalue(manhattanHeuristic(n,goal)); open.add(n); } else { if(gScore<n.getGvalue()) { gScoreIsBest = true; } } if(gScoreIsBest) { n.setGvalue(gScore); n.setFvalue(n.getGvalue()+n.getHvalue()); } } } return null; } What I have found out is that it always fails whenever there's an obstacle in the path. If I'm running it on 'open terrain', it seems to work. It seems to be affected by this part: || map.isWalkeable(n) Though, the isWalkeable function seems to work fine. If additional code is needed, I will provide it. Your help is greatly appreciated, Thanks :)
