• Programming tourism

  - by Andrew_B

  I'm going on vacation to Paris, France for 10 days. Actually, it's my girlfriend's wish to go there but I'm not very interested in visiting, sightseeing, etc. Recently, I came up with an idea of trying to do something like programming tourism. :) I'd like to do something related to programming in a startup-like company. I do not want a salary or any kind of compensation. I want to overview process, social aspects, environment and "what it feels like" to development software in another country. I'm from Russia. I've been a software developer since 2003. I prefer C#4 but I'm ready to use anything Turing-complete. I have some MS certifications and am familiar with all .NETs since 1.1. Currently I'm finishing PhD in CS. I'm interested in multidimensional indexing and I can turn any piece of data and code to OLAP system. :) But it'd take too much time. What can I do? I have no more than one week. I want a totally complete project in a short amount of time. Implement some features in well-tested project Do a code review Debug memory, performance and concurrency issues Do unit testing So, about the questions: Is it legal? I'm ready to sign NDA if it's necessary. I'll have tourist visa. Is it possible? I'm really sure that bureaucratic companies with lots of HRs and PMs will not allow such experiments. But small companies can afford it. I'm ready to guarantee support on my code after leaving home :) P.S. I still havn't started learning French :) I hope it will not take too much time :) P.P.S. Yes, it's girlfriend-approved. What's in it for me? It's fun. It's fun to see new systems and people who created them. It's fun to complete meaningful things. Quickly. What's in it for them? Feature, debug, review or test. If my short-term colleagues will like this style of working I can invite them to make same trip into my company :) I think in Russia it's even more exciting :)

• In what order does the Asset-Pipeline in Ruby on Rails load JavaScript Files? [on hold]

  - by psycatham

  So, when I decided to remove the tags <script></script> and benefit from the asset-pipeline instead, complications took place. I am working with Google Maps' API V3, and to benefit from their functions and objects that their code provides, you have load the link first <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"></script> Basically, If I put this line before their code, and put their code in script tags, things work out pretty perfecty, but when I use javascript_include_tag instead of script tag in html and copy my code to the file I pointed at -Like This - <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"></script> <%=javascript_include_tag "map_new_marker_drag"%> , the asset-pipeline seems to load That file before loading the link of Google Maps API, thus I get the error : - Uncaught ReferenceError : google is undefined I tried putting the link in javascript_include_tag too -Like this- <%=javascript_include_tag "https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places" %> <%=javascript_include_tag "map_new_marker_drag"%> , and it generated this <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&amp;libraries=places"></script> <script src="https://maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/17/2/%7Bmain,places%7D.js" type="text/javascript"></script> <script src="/assets/map_new_marker_drag.js?body=1"></script> and the same error Uncaught ReferenceError : google is undefined. Do I have to put it in another order? what am I missing about the asset-pipeline mechanisms? What should I do to make the link load before the code so to benefit from their objects and get rid of the error? PS : I tried using jquery functions and so , but I seem not to make it happen. If you still think this is a proper solution, please provide me some code I can use this is the jquery function I used jQuery(function($) { // Asynchronously Load the map API var script = document.createElement('script'); script.src = "http://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize"; document.body.appendChild(script); var scriptTwo = document.createElement('script'); scriptTwo.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"; document.body.appendChild(scripTwo); });

• From 20,663 issues to 1 issue&ndash;style-copping C5.Tests

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2014/05/28/from-20663-issues-to-1-issuendashstyle-copping-c5.tests.aspxI recently became interested in the potential of the C5 Collections solution from http://www.itu.dk/research/c5/, however I was dismayed at the state of the code in the unit test project, so I set about fixing the 20,663 issues detected by StyleCop. The tools I used were the latest versions of: My 64-bit development PC running Windows 8 Update with 8Gb RAM Visual Studio 2013 Ultimate with SP2 ReSharper GhostDoc Pro My first attempt had to be abandoned due to collision of class names which broke one of the unit tests. So being aware of this duplication of class names, I started again and planned to prepend the class names with the namespace name. In some cases I additionally prepended the item of the C5 collection that was being tested. So what was the condition of code at the start? Besides the sprawl of C# code not written to style cop standard, there was: 1) Placing of many classes within one physical file. 2) Namespace within name space that did not follow the project structure. 3) As already mentioned, duplication of class names across namespaces. 4) A copyright notice that spawled but had to be preserved. 5) Project sub-folders were all lower case instead of initial letter capitalised. The first step was to add a stylecop heading plus the original heading contained within a region, to every file. The next step was to run GhostDoc Pro using its “Document File” option on every file but not letting it replace the headers, I had added. This brought the number of issues down to 18,192. I then went through each file collapsing each class and prepending names as appropriate. At each step, I saved the changes to my local Git. The step was to move each class to its own file and to style-cop each file. ReSharper provides a very useful feature for doing this which also fixes missing “this.” and moves using statements inside the namespace. Some classes required minimal work whereas others required extensive work to reach the stylecop standard. The unit tests were run at each split and when each class was completed. When all was done, one issue remained which I will need to submit to stylecop team for their advice (and possibly a fix to stylecop). The updated solution has been made available at https://c5stylecopped.codeplex.com/releases/view/122785.

• The term "interface" in C++

  - by Flexo

  Java makes a clear distinction between class and interface. (I believe C# does also, but I have no experience with it). When writing C++ however there is no language enforced distinction between class and interface. Consequently I've always viewed interface as a workaround for the lack of multiple inheritance in Java. Making such a distinction feels arbitrary and meaningless in C++. I've always tended to go with the "write things in the most obvious way" approach, so if in C++ I've got what might be called an interface in Java, e.g.: class Foo { public: virtual void doStuff() = 0; ~Foo() = 0; }; and I then decided that most implementers of Foo wanted to share some common functionality I would probably write: class Foo { public: virtual void doStuff() = 0; ~Foo() {} protected: // If it needs this to do its thing: int internalHelperThing(int); // Or if it doesn't need the this pointer: static int someOtherHelper(int); }; Which then makes this not an interface in the Java sense anymore. Instead C++ has two important concepts, related to the same underlying inheritance problem: virtual inhertiance Classes with no member variables can occupy no extra space when used as a base "Base class subobjects may have zero size" Reference Of those I try to avoid #1 wherever possible - it's rare to encounter a scenario where that genuinely is the "cleanest" design. #2 is however a subtle, but important difference between my understanding of the term "interface" and the C++ language features. As a result of this I currently (almost) never refer to things as "interfaces" in C++ and talk in terms of base classes and their sizes. I would say that in the context of C++ "interface" is a misnomer. It has come to my attention though that not many people make such a distinction. Do I stand to lose anything by allowing (e.g. protected) non-virtual functions to exist within an "interface" in C++? (My feeling is the exactly the opposite - a more natural location for shared code) Is the term "interface" meaningful in C++ - does it imply only pure virtual or would it be fair to call C++ classes with no member variables an interface still?

• dual boot ubuntu installation mishap

  - by user590849

  I have Windows 7 pc ,where i had 2 partitions, a c drive for my system files and a d drive for my data. I decided to install ubuntu 11.10 a couple of days ago and thought of install it in a separate partition of its own. So i made a separate Linux partition of 30GB. I downloaded ubuntu on my usb stick and installed. During the installation process i was asked where to install ubuntu so i opened up a screen that was similar to this one There were six partitions present ( I had made only 3 partition via windows). Their names were totally different from the ones that i had given in windows. So i selected a drive which had the same size as my Linux partition that i had made in windows ( no other partition had the same size). I clicked on install now and got an error message saying that "There was no root folder set". I set the newly made partition as my root folder and clicked install now. Now out of the 6 partitions that were created 3 were logical ( i had only created 3 partitions in windows). As soon as i clicked install now, the system asked me where i wanted to put my "swap space". I selected one of the logical drives and hit install. Ubuntu successfully installed on my system and at the end it asked me to reboot. I did and got the following error message: "missing operating system". I was shocked. I tried my windows recovery disk ( that i had gotten when i had purchased my laptop) and there i went into startup repair. In the startup repair option i was not able to locate windows. The system asked me to click the "Load drivers" button to load the drivers to my harddrive where windows was installed, but i could not locate any drivers to my harddrive. I tried this several times but to no success. I panicked and installed ubuntu, now this time click "ok" at every step( not worrying about the partition and all). The os installed correctly and i am now able to access my harddrive. NO data within the c drive is lost. All the windows system files are intact. I wish to recover my windows installation. How do i go about it? Thank you in advance. I do not want to format my computer and install windows again.

• WiFi on Ubuntu 12.04 custom: downloading unbearably slow

  - by Mark

  iwconfig reports 11 Mbps, yet I've seen as low as <1 KBps. This is the latest in my laundry list of Ubuntu problems in a dual-boot machine (cyberpowerpc custom, intel i7-3820, nvidia gtx 570). I received it two days ago, Windows 7 running fine, still having problems with Ubuntu. The browsing is intermittent but unacceptable. e.g. I could get to this site last night but I couldn't post this question. The downloading is unbearably slow, I can't download anything or install any packages because the speed is so slow. e.g. I am trying to install vim which is inexplicably missing from my 12.04 install (add another one to the problems list) and my download speed reported in the terminal was 241 B/s. Yes, bytes. iwconfig reports 11 Mbps, which further adds to the confusion. User@ubuntu:~$ iwconfig lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"linksys" Mode:Managed Frequency:2.437 GHz Access Point: 00:18:39:76:2C:A1 Bit Rate=11 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:54 Invalid misc:18 Missed beacon:0 eth0 no wireless extensions. Any ideas? I see this is a problem a lot of people, but none of the on line solutions have worked for me so far. e.g. one site recommends editing the ath9k.conf file in /etc/modprobe.d, yet this file isn't even in the folder: User@ubuntu:/$ cd etc/modprobe.d User@ubuntu:/etc/modprobe.d$ ls alsa-base.conf blacklist-oss.conf blacklist-ath_pci.conf blacklist-rare-network.conf blacklist.conf blacklist-watchdog.conf blacklist-firewire.conf dkms.conf blacklist-framebuffer.conf nvidia-current_hybrid.conf blacklist-modem.conf nvidia-graphics-drivers.conf I think the nvidia gpu might be mucking things up. I had the "blinking cursor" problem when installing in the first place, and then I had the monitor out of range problem as well. I have my faithful Asus laptop, which is running Ubuntu 12.04 just fine. The only difference is executing host -t SOA local in the terminal gives User@ubuntu:~$ host -t SOA local local has SOA record local. nobody.localhost. 42 86400 43200 604800 10800 in my new machine, and the command reports Host local. not found in the laptop. Help would be most welcome, as I am in danger of reverting back to Windows. I'm seriously considering it. Sorry for the length, trying to show my effort in resolving the issue and include terminal snippets that might be helpful.

• Are there new flexible texteditors? [closed]

  - by RParadox

  Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

• Redesigning an Information System - Part 1

  - by dbradley

  Through the next few weeks or months I'd like to run a small series of articles sharing my experiences from the largest of the project I've worked on and explore some of the real-world problems I've come across and how we went about solving them. I'm afraid I can't give too many specifics on the project right now as it's not yet complete so you'll have to forgive me for being a little abstract in places! To start with I'm going to run through a little of the background of the problem and the motivations to re-design from scratch. Then I'll work through the approaches taken to understanding the requirements, designing, implementing, testing and migrating to the new system. Motivations for Re-designing a Large Information System The system is one that's been in place for a number of years and was originally designed to do a significantly different one to what it's now being used for. This is mainly due to the product maturing as well as client requirements changing. As with most information systems this one can be defined in four main areas of functionality: Input – adding information to the system Storage – persisting information in an efficient, searchable structure Output – delivering the information to the client Control – management of the process There can be a variety of reasons to re-design an existing system; a few of our own turned out to be factors such as: Overall system reliability System response time Failure isolation and recovery Maintainability of code and information General extensibility to solve future problem Separation of business and product concerns New or improved features The factor that started the thought process was the desire to improve the way in which information was entered into the system. However, this alone was not the entire reason for deciding to redesign. Business Drivers Typically all software engineers would always prefer to do a project from scratch themselves. It generally means you don't have to deal with problems created by predecessors and you can create your own absolutely perfect solution. However, the reality of working within a business is that the bottom line comes down to return on investment. For a medium sized business such as mine there must be actual value able to be delivered within a reasonable timeframe for any work to be started. As a result, any long term project will generally take a lot of effort and consideration to be approved by those in charge and therefore it might be better to break down the project into more manageable chunks which allow more frequent deliverables and also value within a shorter timeframe. As the only thing of concern was the methods for inputting information, this is where we started with requirements gathering and design. However knowing that there might be more to the problem and not limiting your design decisions before the requirements is key to finding the best solutions.

• ADF Real World Developers Guide Book Review

  - by Grant Ronald

  I'm half way through my review of "Oracle ADF Real World Developer's Guide" by Jobinesh Purushothaman - unfortunately some work deadlines de-railed me from having completed my review by now but here goes.  First thing, Jobinesh works in the Oracle Product Management team with me, so is a colleague. That declaration aside, its clear that this is someone who has done the "real world" side of ADF development and that comes out in the book. In this book he addresses both the newbies and the experience developers alike.  He introduces the ADF building blocks like entity objects and view obejcts, but also goes into some of the nitty gritty details as well.  There is a pro and con to this approach; having only just learned about an entity or view object, you might then be blown away by some of the lower details of coding or lifecycle.  In that respect, you might consider this a book which you could read 3 or 4 times; maybe skipping some elements in the first read but on the next read you have a better grounding to learn the more advanced topics. One of the key issues he addresses is breaking down what happens behind the scenes.  At first, this may not seem important since you trust the framework to do everything for you - but having an understanding of what goes on is essential as you move through development.  For example, page 58 he explains the full lifecycle of what happens when you execute a query.  I think this is a great feature of his book. You see this elsewhere, for example he explains the full lifecycle of what goes on when a page is accessed : which files are involved,the JSF lifecycle etc. He also sprinkes the book with some best practices and advice which go beyond the standard features of ADF and really hits the mark in terms of "real world" advice. So in summary, this is a great ADF book, well written and covering a mass of information.  If you are brand new to ADF its still valid given it does start with the basics.  But you might want to read the book 2 or 3 times, skipping the advanced stuff on the first read.  For those who have some basics already then its going to be an awesome way to cement your knowledge and take it to the next levels.  And for the ADF experts, you are still going to pick up some great ADF nuggets.  Advice: every ADF developer should have one!

• Taking too long to get skills for entry level programmer position [closed]

  - by greenonion

  I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

• Development Approach: User Interface In or Domain Model Out?

  - by Berin Loritsch

  While I've never delivered anything using Smalltalk, my brief time playing with it has definitely left its mark. The only way to describe the experience is MVC the way it was meant to be. Essentially, all the heavy lifting for your application is done in the business objects (or domain model if you are so inclined). The standard controls are bound to the business objects in some way. For example, a text box is mapped to an object's field (the field itself is an object so it's easy to do). A button would mapped to a method. This is all done with a very simple and natural API. We don't have to think about binding objects, etc. It just works. Yet, in many newer languages and APIs you are forced to think from the outside in. First with C++ and MFC, and now with C# and WPF, Microsoft has gotten it's developer world hooked on GUI builders where you build your application by implementing event handlers. Java Swing development isn't so different, only you are writing the code to instantiate the controls on the form yourself. For some projects, there may never even be a domain model--just event handlers. I've been in and around this model for most of my carreer. Each way forces you to think differently. With the Smalltalk approach, your domain is smart while your GUI is dumb. With the default VisualStudio approach, your GUI is smart while your domain model (if it exists) is rather anemic. Many developers that I work with see value in the Smalltalk approach, and try to shoehorn that approach into the VisualStudio environment. WPF has some dynamic binding features that makes it possible; but there are limitations. Inevitably some code that belongs in the domain model ends up in the GUI classes. So, which way do you design/develop your code? Why? GUI first. User interaction is paramount. Domain first. I need to make sure the system is correct before we put a UI on it. There's pros and cons for either approach. Domain model fits in there with crystal cathedrals and pie in the sky. GUI fits in there with quick and dirty (sometimes really dirty). And for an added bonus: How do you make sure the code is maintainable?

• Laptop freezes and seems to crash, but continues working after waiting for a few minutes [closed]

  - by Corwin

  I've had this old notebook laying around and because i was missing a second machine (My wife usually steals the first ;) ) I considered installing Linux. As a php developer I work with Linux servers (usually fedora) on a daily basis and because its an older machine that I want to use for development, linux seemed the best option. Speedwise I expected a good experience, better than Windows 7 on the same machine. The results where terrible. I tried ubuntu 12.04. The shell never got past showing the background. The system doesn't freeze since the mouse still works and I can use ctrl+alt+f2 etc to enter terminal mode. I expected hardware problems en even exchanged the harddisk en Ram memory. No luck though, so I started over and tried 11.10 Same results so I tried 10.04.4 which did install properly. Not sure if unity was the problem, but it seems likely. But then I tried simply things like surfing on the net, the system frooze and I thought it crashed so after a few minutes I pulled the plug and rebooted. But it happened again and I waited. After a few minutes the system came back to life like nothing happened. Long story short. Besides the fact that the entire interface is very sluggish, any and all graphical functions freezes the system. The more elaborate the animation would be, the longer it freezes. I switch chromium from window to fullscreenmode and had to wait 15 minutes to continue. I don't see the animation that's probably supposed to be in between. It just freezes and then after unfreezing its fullscreen. I don't think its a bug. I suspect the problem is with my graphics card. Like I said, its and old system. So old that I can't even find the original Ati drivers anywere. (I'll post the details of my system at the end of my post) I'm at a loss as to what to do next. I tried other Distro's. So far only dreamlinux works normally. Linux Mint won't start as a live CD. I think I simply need a driver update but I can't find them anywhere. Does anyone have the same experience ? Maybe even someone who has or had the same notebook running Ubuntu at some point ? Anyway, here are the specs: http://www.nec-driver.com/nec-driver/NEC-Versa-P550---FP550-Driver_421.html

• How should I refactor switch statements like this (Switching on type) to be more OO?

  I'm seeing some code like this in our code base, and want to refactor it: (Typescript psuedocode follows): class EntityManager{ private findEntityForServerObject(entityType:string, serverObject:any):IEntity { var existingEntity:IEntity = null; switch(entityType) { case Types.UserSetting: existingEntity = this.getUserSettingByUserIdAndSettingName(serverObject.user_id, serverObject.setting_name); break; case Types.Bar: existingEntity = this.getBarByUserIdAndId(serverObject.user_id, serverObject.id); break; //Lots more case statements here... } return existingEntity; } } The downsides of switching on type are self-explanatory. Normally, when switching behavior based on type, I try to push the behavior into subclasses so that I can reduce this to a single method call, and let polymorphism take care of the rest. However, the following two things are giving me pause: 1) I don't want to couple the serverObject with the class that is storing all of these objects. It doesn't know where to look for entities of a certain type. And unfortunately, the identity of a type of ServerObject varies with the type of ServerObject. (So sometimes it's just an ID, other times it's a combination of an id and a uniquely identifying string, etc). And this behavior doesn't belong down there on those subclasses. It is the responsibility of the EntityManager and its delegates. 2) In this case, I can't modify the ServerObject classes since they're plain old data objects. It should be mentioned that I've got other instances of the above method that take a parameter like "IEntity" and proceed to do almost the same thing (but slightly modify the name of the methods they're calling to get the identity of the entity). So, we might have: case Types.Bar: existingEntity = this.getBarByUserIdAndId(entity.getUserId(), entity.getId()); break; So in that case, I can change the entity interface and subclasses, but this isn't behavior that belongs in that class. So, I think that points me to some sort of map. So eventually I will call: private findEntityForServerObject(entityType:string, serverObject:any):IEntity { return aMapOfSomeSort[entityType].findByServerObject(serverObject); } private findEntityForEntity(someEntity:IEntity):IEntity { return aMapOfSomeSort[someEntity.entityType].findByEntity(someEntity); } Which means I need to register some sort of strategy classes/functions at runtime with this map. And again, I darn well better remember to register one for each my my types, or I'll get a runtime exception. Is there a better way to refactor this? I feel like I'm missing something really obvious here.

• Trying to find resources to learn how to test software [closed]

  - by Davek804

  First off, yes this is a general question, and I'd be perfectly happy to move this to another portion of SE, but I didn't see a more fitting sub. Basically, I am hoping a more experienced QA tester can come along and really fill in some basics for me. So far, websites seem to be sparse in terms of explaining languages involved, basic practices, etc. So, I'm sorry in advance if this is too general, but towards the end of this post I ask some specific questions if it's just absolutely unacceptable to speak in general terms. I just landed a position as Junior Systems and QA Engineer with a social media startup. Their QA and testing is almost nonexistent, so if I do a good job, I imagine I'll find a lot of bugs and have a secure role in the business. I'm pretty good with the systems aspect of my role, but I need to learn more about the QA and testing aspects. We run hardware that's touchscreen based - the user can use and interact with the devices. So, in terms of my QA role, in the short term, I need to build scripts to test the hardware/software as a 'user' to try to uncover bugs. First off, what language should these scripts be written in? Does anyone have some examples? What about the longer term 'automated testing'? I'm familiar with regression testing as the developer adds in new features, sure, but the 50,000 other types of testing, not so much. Most of our hardware runs dotnet/C# code, with some of the servers running Java - but I don't expect to need to run tests on the Java side at this point. I hope to meet with one developer today and try to get a good idea of the output from the hardware so that I can 'mock' this data that gets sent to servers, to try to bugtest. Eventually, we will be moving the hardware to be closer to where I live and work, so that I can test virtually and on real hardware. So a lot of the bugs we're dealing with now are like this: the Local Server, which kiosks report their data to gets updated from the kiosks, but the remote server does not. Or, vis versa when the user registers on a kiosk, the remote server updates but the local server does not. But yeah, without much more detail, I imagine a lot of this info isn't helpful. I've bought a book "How Google Tests Software", but it's really a book more about 'how their software testing is different from Microsoft'. It doesn't teach how to test so much as why their methods are better. Does anyone have a good book that I can buy? An ebook maybe? My local Barnes and Noble kinda had a terrible selection. I also figure a book from 2005 is not necessarily that good either.

• Reinstall Acer OEM Windows 8, Windows 8 Recovery for Acer Aspire V5 122p

  - by stwindr

  My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).

• MailEnable - Configuring TLS for secure SMTP (Gmail)

  - by Buckers

  I have the latest version of MailEnable Pro installed on a new server that I'm setting up. Sending & receiving works fine with a new email account that I have set up, however I am now trying to configure GMail to use the mailserver for outgoing SMTP. I've done the following so far: Creating a self-cert SSL certficiate Ticked "Enable TLS" on the General tab of the SMTP connector properties Ticked "Send using TLS if remote server supports it" on the Outbound tab of the SMTP connector properties Selected the new self-cert SSL certificate on the SSL tab of the localhost server properties. Given permissions to IME_System on the new certificate However, Gmail is still giving me the following error: Authentication failed. Please check your username/password. [Server response: 454 TLS not available due to temporary reason code(454) ] I'm trying to connect on port 25, (someone told me you can still do this and you dont have to connect on 465). Is this right? Or do I need to tell MailEnable to use port 465? Am I missing something? Thanks, Chris.

• iScsiPrt error event ID 5

  - by AZee

  Event Log: "Failed to setup initiator portal. Error status is given in the dump data." This is being recorded every 3/100's of a second. We are using MS iSCSI Initiator on Windows Server 2003, Dell 2970 w/4GB (PAE). I am sure that this was configured by Dell initially. I have no idea what changes or mods were made since the company installed this machine until now. (I'm a new User so the lovely and vibrant screen images had to be removed. They were quite pretty and I am sure you would have been very moved and appreciative of them.) It appears that everything is installed correctly and the 5TB bound volume is accessible but I have never worked with iScsi before so I plead total ignorance. In searching I have found this to be a fairly sparce and bland documented subject. I'd like two things... First, to get rid of the error msg being logged. MS says it can be ignored if everything is working but it chews up resources logging it and I don't feel comfortable about any errors on my servers. I want to correct whatever is causing this problem. Secondly, being totally green to this, I would like to confirm that the setup is optimized and we are taking advantage of all features available. Although there are 3 NIC's in this machine it appears that the initiator is only configured for the Broadcom BMC5708C NetXtreme II on our 10.90.1.#, the other 2 NICS are 1GB on the 192.168.0.#. Would additional targets improve performance? If someone who is experienced in configuring the Microsoft iScsi Initiator can help I would really appreciate it since, as I mentioned, everything I have come across has not been of any value at all. Thanks! ~AZ

• What does "single-bit ECC errors were detected on the RAID controller" mean?

  - by jsp

  I have a Dell T7600 with a Perc H710P RAID controller and 4 attached 3TB drives. Over the past few months the RAID controller has been intermittently reporting errors on boot: "no boot device found", "adapter at baseport is not responding", disks frequently reported as missing or failed. I have since replaced the RAID controller, the 4 hard drives, and finally the system's motherboard. After replacing the motherboard and rebooting a few times, I got the error Single bit ECC errors were detected on the RAID controller. Please contact technical support to resolve this issue. After rebooting about 20 more times, I haven't seen the ECC error. The system seems otherwise OK, except for the fact that the disk fans will sometimes start blowing at full blast when the the system is sitting completely idle and not stop until I reboot. Are the ECC errors in memory on the RAID controller? Or, does the RAID controller map in system memory, and the ECC errors are really in system memory? Or, are the ECC errors in the 1GB cache that resides in the RAID controller?

• Unable to Install SQL Server on Server 2012

  - by Jeff

  The problem I have been trying to install SQL Server 2012 on Windows Server 2012. I continually get the same error: Managed SQL Server Installer has stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: scenarioengine.exe Problem Signature 02: 11.0.3000.0 Problem Signature 03: 5081b97a Problem Signature 04: Microsoft.SqlServer.Chainer.Setup Problem Signature 05: 11.0.3000.0 Problem Signature 06: 5081b97a Problem Signature 07: 18 Problem Signature 08: 0 Problem Signature 09: System.IO.FileLoadException OS Version: 6.2.9200.2.0.0.272.79 Locale ID: 1033 Additional Information 1: c319 Additional Information 2: c3196e5863e32e0baf269d62f56cbc70 Additional Information 3: 422d Additional Information 4: 422d950c58f4efd1ef1d8394fee5d263 What I've tried After initial googling, I've tried the following things: Go through the list of hardware and software pre-reqs. All the software seems to be there by default on Server 2012 and my hardware meets the reqs. Copy the installation media to the local drive and try to install from that (rather than a DVD). This produced the same error. Based on another error message, I installed .NET 4.0 (which apparently is not on Server 2012 out of the box). Same error. Install from command line. This didn't work either, but it gave me a different error: Error: Unhandled Exception: System.IO.FileLoadException: Could not load file or assembl y 'Microsoft.SqlServer.Configuration.Sco, Version=11.0.0.0, Culture=neutral, Pub licKeyToken=89845dcd8080cc91' or one of its dependencies.

• High CPU usage by 'svchost.exe' and 'coreServiceShell.exe'

  - by kush.impetus

  I am having a laptop running on Windows 7 Ultimate 32-bit. Since past few days, my laptop is facing a serious problem. Whenever I connect to Internet, either svchost.exe or coreServiceShell.exe or both hog the CPU. The coreServiceShell.exe consumes a lot of RAM also. Going into the details, I found that high CPU usage of svchost.exe is caused by Network Location Awareness service. And the high CPU usage of coreServiceShell.exe is caused by Trend Micro Titanium Internet Security 2012. That kind'a makes me think that Trend Micro may be the root of the problem. After further testing, I found that if I use IE or Firefox to browse the Internet, immediately after connecting to Internet, things are normal. See and But if I use Google Chrome, the coreServiceShell.exe hogs both CPU and RAM. At this point, if I disconnect the Internet, the CPU and RAM usage by coreServiceShell.exe continues to be high till I close the Chrome. Also, when I close the Chrome, while Internet is connected, svchost.exe continues to hog CPU but coreServiceShell.exe leaves the race. That makes think that Chrome is the root of the problem, but again, tracing coreServiceShell.exe takes me back to Trend Micro Internet Security. Stopping the Protection by the Trend Micro Internet Security doesn't help either (I am not able to stop its services though). I have updated the Chrome, but no help. I just can't figure out who is the culprit. I can't do without the Google Chrome (of course, by not using it) because of its immensely useful and indispensable features both during browsing and development. Secondly, I can't uninstall the Trend Micro Internet security Suite since it still has few months before it expires and is proving me reliable protection. What could be the cause of the problem and what can I do to resolve this? Thanks in advance
