  • hybrid cable for QSFP to CX4 convertion

    - by John-ZFS
    here is a hybrid cable for QSFP to CX4. Will this fit SFP+ ports? Deeply confused by standards and struck in a situation with wrong hardware selection!Personally have not seen the ports/hardware and hence the obviously stupid question! thanks for stopping by and bearing with me. http://www.cablesondemand.com/pcategory/72/category/QSFP+-+CX4/URvars/Catalog/Library/InfoManage/QSFP_TO_CX4_COPPER_CABLES.htm

  • Linux depends hell when installing a small mp3 player...

    - by smwikipedia
    I try to install a small audio player named "Audacious" with the following command: sudo apt-get install audacious and it tells me that it depends audacious-plugins, so I try to install the audacious-plugins, one thing leads to another, there're numerous depends and it is just impossible to install all of them manually... Is it even possible to install a software on ubuntu linux? Is there a way to auto install all the depends? (I have never seen such a stupid software manager.) Many thanks.

  • Mouse not working in flash, Ubuntu!

    - by data_jepp
    I'm so sick of this problem. Some time back I changed to windows because of this, and now I'm back in Ubuntu and guess what. This still hasn't been fixed. How is it possible that something so simple yet crippling isn't fixed faster? This is why windows always wins in the end, because of stupid details like this.

  • What are the small details Windows and Linux users will trip on when using OSX for the first time?

    - by badp
    Like any other Apple product, OS X prides itself on the little details. When, earlier last week, I used my professor's Mac briefly to give a quick project presentation (mine decided to do a chkdsk at the wrong time, heh), I got the distinct feeling some were put intentionally to make the uninitiated look stupid. What are the small usability details that Windows and Linux users will trip on when their Mac using friend lend them their beloved Mac for some quick web browsing?

  • Convert FAT32 to NTFS, risk/time?

    - by Rakward
    After a quick search I found that through a command prompt I can convert a drive from FAT32 to NTFS without losing data(see here). What I want to ask here is, how safe is this method on a 1.5 TB drive with 500 GB of data? What are the chances of this freezing up(or is there really nothin to worry about) and what is the probable time, a couple of minutes or a whole hour? Sorry if this seems like a stupid question, just want to play on the safe side here ...

  • Why are monitors so poor?

    - by ULTRA_POROV
    72 ppi is nothing. And we have been stuck with this for 20 years. Why do we need to resort to stupid tech like anti-aliasing instead of resolving the core of the issue, more pixels per inch!!! It is really surprising considering all the progress cpu's, video cards, etc. have made.

  • How to find a user's (or mine) access rights on Windows Server 2008?

    - by Faiz
    I was given access to a Windows Server 2008 box and I need to check what all permissions I have on that box (if possible in the entire domain). I don't have access to domain controller and I don't want to write LDAP queries but just some GUI option or some command line stuff. Is there anyway? PS: I am not in to network administration, I am a BI developer. Pardon me if asked a stupid question.

  • Windows 7 Favorite folder doesn't work

    - by Razor Storm
    So recently I did a very stupid thing and accidentally deleted my APPDATA (LOL yes), and now the favorite folder doesn't work anymore. The favorite folder I am refering to is the one in windows explorer (not the horrid IE) in windows 7, which appears on the left of windows explorer windows. The %USERPROFILE%/Favorite folder still works correctly, but the favorite folder in the shell doesn't point there, instead it points to a nonexistant and broken location, how do i fix this problem?

  • Virtual Machine for software renting service

    - by Vilis
    I am currently trying to figure out which solution would be best for software renting service (with proper licensing and stuff). I know its kinda stupid and so on, but I just have to develop it. Long story short - user can connect to a virtual machine (with windows guest os) using vnc and use some specific software for some specific time (eg., 1 hour). I have already considered VirtualBox, Xen and some other, but maybe somebody has a better idea. Thanks.

  • where to get an IBM jre for 64-bit Windows?

    - by Michael Mao
    I know this is stupid: I couldn't find anything from IBM website about where to download an IBM jre (specifically, IBM jre1.6.0 J9 2.4 SR6) for a 64-bit Windows OS. Google takes me to a link which looks similar, but that jre would only work on an IBM product, I assume their own server/workstation or something like that. So I've been stuck by this for quite some time... I couldn't believe there is no such a "previous version repository" or something similar on IBM website :( Thanks for any suggestion in advance.

  • httpd.conf ruined - can't access my vps anymore

    - by Jazerix
    Okay, so this may be incredible stupid But I was configuring my httpd.conf file yesterday. After a server restart, I can no longer access it. Port 80 is working fine, and it displays my webpages, however when I access the site via ssh, it just says the connection was refused. I cannot access webmin which is port 10000 or access it via ftp :/ Do I need to recreate the whole site or is there a way to get into it? I think I messed up the virtual hosts :)

  • How can I tell if I'm behind a portal or proxy

    - by user19269
    I'm testing out a Content management system on my computer and have emailed their support for a problem regarding login.. They've replied back and asked if my CMS is behind a portal or proxy. I feel kind of stupid for not knowing this, but how do I find out? Everything is local (eg, hosted on my computer, etc). Thanks in advance!

  • Dual boot, win7 & ubuntu. Gparted, resize not move. Performance?

    - by data_jepp
    I installed dual boot on a computer that already had win7 installed. The question here is about gparted ability to move partitions. I made place for ubuntu in the computers "Data" partition, by resizing it. But I canceled the "move" action. Was that incredibly stupid, or is this care? Maybe performance is affected. Can this effect the hd's lifespan? The computer is UL30A.

  • How to know whether to create a general system or to hack a solution

    - by Andy K
    I'm new to coding , learning it since last year actually. One of my worst habits is the following: Often I'm trying to create a solution that is too big , too complex and doesn't achieve what needs to be achieved, when a hacky kludge can make the fit. One last example was the following (see paste bin link below) http://pastebin.com/WzR3zsLn After explaining my issue, one nice person at stackoverflow came with this solution instead http://stackoverflow.com/questions/25304170/update-a-field-by-removing-quarter-or-removing-month When should I keep my code simple and when should I create a 'big', general solution? I feel stupid sometimes for building something so big, so awkward, just to solve a simple problem. It did not occur to me that there would be an easier solution. Any tips are welcomed. Best

  • My Interview with Microsoft

    - by Victor Hurdugaci
    This post is for those who want to apply or have already applied (but not finished the interview) for a Microsoft Job. The recruitment process is quite similar for everyone and consists of a few steps. Application E-Mail Interview Phone Interview On Site Interview I will tell you my story and how I went through the four phases. 1. Application My blog's title (Ex Nihilo Nihil Fit) means "Nothing Comes Out of Nothing". You can't get a job at Microsoft by not doing anything - this is true for anything else. The first step you need to complete is the application process. For this, many options are available. You can... ... apply online on Microsoft's Careers website as I did ... send your CV to different e-mail addresses (there are some dedicated e-mails for different positions) ... apply through some 3rd party organization (job shop, campus recruitment, job agency, etc) On MS Careers you just have to post your CV and choose the job you want. That's all! No recommendation letter, no cover letter, no nothing. Of course, not every CV passes the selection process. Here are some tips for improving your resume (worked for me): Don't write it just before applying! Write a draft version, wait a few days and then review it. This way you will find a lot of mistakes and stupid things you wrote initially. If you review it immediately after writing, your mind will not be criticism oriented and will just ignore mistakes. Repeat the write-wait-review process as many times as necessary, until you find that the review revealed no mistakes. After you did the final review and the CV is bullet-proof, ask others to review it. They will definitely find inconsistencies and mistakes and this will make you feel stupid. This is good because will open your eyes will make you go into an 'I want to improve' mode. You'll try to correct everything. After you come up with a modified version go again through steps 1 and 2. Repeat this as many times as necessary. [Special thanks to Lucian Sasu, Nadia Comanici, Andrei Ciobanu, Monica Balan and Lavinia Tanase for reviewing my CV!] Make it short and give only relevant facts. Initially, I come up with a 5 pages CV because I wrote every single technology with which I worked. There were a lot irrelevant things, I wrote Windows Workflow Foundation just because I played with it for a few days. I added extensive descriptions for every project, made a personal details section (name, birth date, address, etc) of 1/2 page. Others suggested to cut everything that was not necessary. You don't need to give extensive descriptions, just add a few words. For example, I wrote "VS Image Visualizer - Visual Studio 2008 debug visualizer for images" and added a link to the project's page - you submit formatted andcan embed links. Add something that makes it different. I don't know if this makes a difference, but I added some lines to separate items just like in the picture below. Definitely Microsoft gets thousands of CVs per day. You need something special. Don't lie! Tell exactly what you did and what is the proficiency level of your skills. For example, don't write "Advanced" for UML if you don't know the difference between composition and aggregation. Be realistic and don't under/over estimate yourself. Use the spell chick. Make sure everything is written in correct English and there are no grammar/spelling mistakes. Noddy likes a WC with grammar mi takes. You mght fail just because of that. Once you completed your CV, choose the job that suits best your needs, apply and wait... The waiting is a problem because all these big companies like Microsoft, Google, Mozilla, Apple, etc. will contact you only if they find something interesting in your application. If you're not suitable, then no rejection is sent. I applied for an Intern Software Development Engineer position at Microsoft Redmond. I cannot apply for a full time position because I want to finish the master program on time, in the next summer - an internship is just what I need. 2. E-Mail Interview January 20, 2010. Two months since I submitted the CV. I wasn't hoping anymore that MS will contact me, when I got an e-mail titled: "Victor Hurdugaci ES DK" from Holly Peterson saying: Read more >>

  • CQRS &ndash; Questions and Concerns

    - by Dylan Smith
    I’ve been doing a lot of learning on CQRS and Event Sourcing over the last little while and I have a number of questions that I haven’t been able to answer. 1. What is the benefit of CQRS when compared to a typical DDD architecture that uses Event Sourcing and properly captures intent and behavior via verb-based commands? (other than Scalability) 2. When using CQRS what do you do with complex query-based logic? I’m going to elaborate on #1 in this blog post and I’ll do a follow-up post on #2. I watched through Greg Young’s video on the business benefits of CQRS + Event Sourcing and first let me say that I thought it was an excellent presentation that really drives home a lot of the benefits to this approach to architecture (I watched it twice in a row I enjoyed it so much!). But it didn’t answer some of my questions fully (I wish I had been there to ask these of Greg in person!). So let me pick apart some of the points he makes and how they relate to my first question above. I’m completely sold on the idea of event sourcing and have a clear understanding of the benefits that it brings to the table, so I’m not going to question that. But you can use event sourcing without going to a CQRS architecture, so my main question is around the benefits of CQRS + Event Sourcing vs Event Sourcing + Typical DDD architecture Architecture with Event Sourcing + Commands on Left, CQRS on Right Greg talks about how the stereotypical architecture doesn’t support DDD, but is that only because his diagram shows DTO’s coming up from the client. If we use the same diagram but allow the client to send commands doesn’t that remove a lot of the arguments that Greg makes against the stereotypical architecture? We can now introduce verbs into the system. We can capture intent now (storing it still requires event sourcing, but you can implement event sourcing without doing CQRS) We can create a rich domain model (as opposed to an anemic domain model) Scalability is obviously a benefit that CQRS brings to the table, but like Greg says, very few of the systems we create truly need significant scalability Greg talks about the ability to scale your development efforts. He says CQRS allows you to split the system into 3 parts (Client, Domain/Commands, Reads) and assign 3 teams of developers to work on them in parallel; letting you scale your development efforts by 3x with nearly linear gains. But in the stereotypical architecture don’t you already have 2 separate modules that you can split your dev efforts between: The client that sends commands/queries and receives DTO’s, and the Domain which accepts commands/queries, and generates events/DTO’s. If this is true it’s not really a 3x scaling you achieve with CQRS but merely a 1.5x scaling which while great doesn’t sound nearly as dramatic (“I can do it with 10 devs in 12 months – let me hire 5 more and we can have it done in 8 months”). Making the Query side “stupid simple” such that you can assign junior developers (or even outsource it) sounds like a valid benefit, but I have some concerns over what you do with complex query-based logic/behavior. I’m going to go into more detail on this in a follow-up blog post shortly. He also seemed to focus on how “stupid-simple” it is doing queries against the de-normalized data store, but I imagine there is still significant complexity in the event handlers that interpret the events and apply them to the de-normalized tables. It sounds like Greg suggests that because we’re doing CQRS that allows us to apply Event Sourcing when we otherwise wouldn’t be able to (~33:30 in the video). I don’t believe this is true. I don’t see why you wouldn’t be able to apply Event Sourcing without separating out the Commands and Queries. The queries would just operate against the domain model instead of the database. But you’d still get the benefits of Event Sourcing. Without CQRS the queries would only be able to operate against the current state rather than the event history, but even in CQRS the domain behaviors can only operate against the current state and I don’t see that being a big limiting factor. If some query needs to operate against something that is not captured by the current state you would just have to update the domain model to capture that information (no different than if that statement were made about a Command under CQRS). Some of the benefits I do see being applicable are that your domain model might end up being simpler/smaller since it only needs to represent the state needed to process commands and not worry about the reads (like the Deactivate Inventory Item and associated comment example that Greg provides). And also commands that can be handled in a Transaction Script style manner by the command handler simply generating events and not touching the domain model. It also makes it easier for your senior developers to focus on the command behavior and ignore the queries, which is usually going to be a better use of their time. And of course scalability. If anybody out there has any thoughts on this and can help educate me further, please either leave a comment or feel free to get in touch with me via email:

  • Abstraction: The War between solving the problem and a general solution.

    - by Bryan Harrington
    As a programmer, I find myself in the dilemma where I want make my program as abstract and as general as possible. Doing so usually would allow me to reuse my code and have a more general solution for a problem that might (or might not) come up again. Then this voice in my head says, just solve the problem dummy its that easy! Why spend more time than you have to? We all have indeed faced this question where Abstraction is on your right shoulder and Solve-it-stupid sits on the left. Which to listen to and how often? What is your strategy for this? Should you abstract everything?

  • I'm a happy camper

    - by Paul Nielsen
    I’m satisfied with SQL Server 2008. It meets my needs and I can build whatever I want in the database. There’s no feature that it lacks that blocking my development. SQL Server 2008 is what I see when I close my eyes and dream. Maybe I’m just pleased with my current projects, maybe I’m being dense, maybe I lack imagination, tell me if I’m being stupid, but I feel no compelling need for an upgrade. If Microsoft didn’t ship the new version for 3 or 5 more years, I’d be ok with that. I’m sure there...(read more)

  • Using modproxy to get around China's Great Firewall

    - by Yau Leung
    I'm using WIX service and I like it very much. However, one big problem is that some of my colleagues are in China but their IP is blocked. I'm wondering if modproxy can help me. I would like to setup a clean server (not blocked by the stupid Chinese government). Pointed the DNS cname to it and have modproxy get the page in background and send the page to viewers in China. Will it work? If yes, can anyone post any examples? Thanks a million

  • MVC : Does Code to save data in cache or session belongs in controller?

    - by newbie
    I'm a bit confused if saving the information to session code below, belongs in the controller action as shown below or should it be part of my Model? I would add that I have other controller methods that will read this session value later. public ActionResult AddFriend(FriendsContext viewModel) { if (!ModelState.IsValid) { return View(viewModel); } // Start - Confused if the code block below belongs in Controller? Friend friend = new Friend(); friend.FirstName = viewModel.FirstName; friend.LastName = viewModel.LastName; friend.Email = viewModel.UserEmail; httpContext.Session["latest-friend"] = friend; // End Confusion return RedirectToAction("Home"); } I thought about adding a static utility class in my Model which does something like below, but it just seems stupid to add 2 lines of code in another file. public static void SaveLatestFriend(Friend friend, HttpContextBase httpContext) { httpContext.Session["latest-friend"] = friend; } public static Friend GetLatestFriend(HttpContextBase httpContext) { return httpContext.Session["latest-friend"] as Friend; }

  • visual basic coach needed [closed]

    - by Danny
    0 down vote favorite I am trying to learn visual basic. I used to program in gw-basic and have trouble learning vb.net by reading and googling all the time. It takes so much time to find the answers to my programming problems and even then i do not understand the why it have to be done that way. I have beginners questions like finding childwindows using enumwindow. Then googling for hours and hours i do not seem to grasp it (must be my old age). I would like to get someone i could learn from by asking questions about what i want to program and learn from it. not to just finish the program but to learn and understand it too. Someone who dont find questions stupid to ask as i try to build my understanding of the visual basic environment. I hope to communicate by using skype voice or chat or other direct means when time permits it. Cheers, Danny

  • Adaptative interface with Open GL and machine learning in C#

    - by Afnan
    For my Semester project I have to go for any Adaptative Interface Design. My language is C# and I have to Use OpenTK (wrapper for OpenGL). I have an idea that I should show two points and some obstacles and my subject (user) would drag an object from one place to the final place avoiding the Obstacles. Also (s)he can place obstacles randomly. My software should be able to learn some paths by doing test runs and then after learning it should be able to predict the shortest path. I do not know how stupid this idea sounds but it is just an idea. I need help regarding any ideas for adaptative interface possible small projects or if my idea is ok then please can you tell me what should be used to implement it? I mean that along with OpenGl for the Graphics what can I use for machine learning?
