  • PSU failing or Mainboard failing?

    - by Andrei Rinea
    I am having some troubles lately powering on my desktop workstation. While starting up the PC after being off for hours (usually at least 8 hours) it randomly fails to do so. What happens is that : I press the power button; nothing happens I can hear a moderate buzzing noise at the back of the PC (near the PSU); but I can't say for sure that it's not from the mainboard. If I insist pressing the power button a few times in 1-2 minutes it'll start Another route would be that instead of (3) I will plug off the power cable from the PSU and wait for 30 seconds. Then I will press the power on and keep it for 30-60 seconds (I had some success at notebooks with a similar approach). Then I will plug back the cable in the PSU, press only once the power button and it will start normally. Also while running normally I keep hearing some low buzzing which seems to be fan-RPM-related (i.e. when processing images or doing CPU intensive work). What should I look into? UPDATE It's getting worse. It took more than 10 retries today and almost 20 minutes to start the computer. I tried the paperclip trick and the PSU behaves perfectly. I managed to start the computer like so : I pressed the on-button a few times and then left the PC in a pre-startup state (the fans were working the buzzing noise was strong and I went to eat. I thought I won't lit the house on fire so fast and without smelling. Back, after 10-15 min the computer booted up! Discussed with a fellow at Intel and he told me the capacitors on the mainboard are probably a bit shot. If they are shot, he said, it should start up warm perfectly. So I did restart it, warm, a few times (5 sec cooldown and then 40 sec cooldown and it started up perfectly). I can either replace the capacitors on the mainboard (doesn't sound worth it or replace the mainboard (this one sucks too :)) ) FINAL INFO : It was the PSU after all. Although it was powering the IDEs and SATAs the Mainboard power module was failing. I bought another mainboard just to find out that this wasn't the cause. Now I'll have to return it somehow. The spare PSU is now in the computer and doing well.. Although larger (500W), it's like a plane taking off.. I need a better one.

  • Standard Network Tiers in a Distributed N-Tier System

    Distributed N-Tier client/server architecture allows for segments of an application to be broken up and distributed across multiple locations on a network.  Listed below are standard tiers in a Distributed N-Tier System. End-User Client Tier The End-User Client is responsible for sending and receiving requests from web servers and other applications servers and translating the responses so that the End-User can interpret the data effectively. The primary roles for this tier are to communicate with servers and translate server responses back to the end-user to interpret. Business-Specific Functions Validate Data Display Data Send Data to Webserver Web Server Tier The Web server tier processes new requests for information coming in from the HTTP and HTTPS ports. This primarily handles the generation of user interfaces and calls the application server when needed to access Data and business logic when needed. Business-specific functions Send Data to application server Format Data for Display Validate Data Application Server Tier The application server stores and executes predefined business logic that is applied to various pieces of data as the business determines. The processed data is then returned back to the Webserver. Additionally, this server directly calls the database to obtain and store any data used by the system Business-Specific Functions Validate Data Process Data Send Data to Database Server Database Server Tier The Database Server is responsible for storing and returning all data need by the calling applications. The primary role for this this server is storage. Data is stored as needed and can be recalled at any point later in time.

  • What's the best practice to do SOA exception handling?

    - by sun1991
    Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

  • f12 and ctrl + f5 not working correctly

    - by ComatoseDuck
    When I came back to my work computer after being away for a week I found out when I try to clear the cache and refresh the page via ctrl + f5 (or just f5) I get the prompt "Type the Internet address of a document, and Internet Explorer will open it for you" with a drop down list in IE. When I try f5 in Chrome and FF it opens the "Open file" dialog box. When I try to f12 for Dev tools in IE, Chrome & FF it opens up the print dialog box. Why is this happening and what can I do to revert it back to the way it was?

  • How to setup an iTunes library to use between two Macs?

    - by stead1984
    As you can tell this is no where near work related. I have an iMac G5 where my itunes is currently hosted, I have also just got a new MacBook Pro. What I want to be able to do is sync my itunes library from my iMac to my MacBook Pro, that way it can be accessible away from my home network, then if I make any changes to the itunes library (like change a track name) it will sync these changes back once I connect back to the home network. My current itunes contains music, videos, podcasts, playlists and iPhone apps, I would also like iTunes to track play counts collectively between the iMac and the MacBook Pro.

  • MQTT, GWT, ActiveMQ stack to bring jms to the browser

    - by scphantm
    I am in the preliminary stages of architecting a legacy replacement project. They already have sub half second performance on their green screens and they want the same on their web app. We have a 390 mainframe that can handle anything we throw at it but they don't have a good jvm for it, so we have two tiers of websphere servers between the mainframe and the browser, The ui server, and the bl server. For the ui, I'm leaning towards GWT. But one thing that I think would seal the deal is to add messaging capabilities to the browser. The idea is say you click on a link that displays a second panel of information, instead of the classic GWT where it triggers a GWT-RPC call to the ui server, the ui server routs it to the bl server, the bl sends it to the mainframe and back out, it drops an MQTT message directly to the bl server or directly to the mainframe. Say writes go to the bl, reads go to the mainframe. This is an easy enough thing in classic jms because you can issue a message that has an expected response. Then have your callback ready to get the resonse. But from what I'm reading so far. It looks like mqtt doesn't have that. It looks like it's strictly fire and forget, which would make it really tough to come up with a way to get a response back to the workstation that called it. Am I right here? Has anyone tried this stack before with gwt.

  • Sound in Ubuntu 12.10 on Chromebook

    - by Paul Mennega
    I've got an HP Chromebook 14 that I've rooted and installed Ubuntu via Crouton (upgraded to 12.10) and most things are working nicely. One issue that I am having trouble solving relates to sound. I've got sound output that I can control via the individual app (e.g. Youtube), but when trying to control the volume via the built-in xfce4-mixer, I get the following error: GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem. Opening a terminal, I can run the alsamixer and control the volume levels. It is reporting back that the card is CRAS. I'd love to be able to do it from XFCE and the built-in mixer. I've tried re-installing the GStreamer packages, but no luck. It seems like I am close but not sure where to go from here. On a maybe unrelated note, plugging headphones into the headphone jack in Ubuntu also does not stop the sound from coming from the speakers and nothing comes through the headphones. Switching back to ChromeOs, everything works as expected, so I think that it's a driver issue.

  • Failed to load session gnome-fallback, after messing with metacity

    - by Carlito
    I am using Ubuntu 12.04 with gnome-session-fallback (Gnome Classic in the login menu). I wanted to remove window borders from metacity and stumbled across this post which basically changes window->mwm_decorated from TRUE to FALSE, which should remove the window borders in metacity. I know that it is also possible to change your GTK theme to one without window borders, but I wanted to try this solution. So I downloaded the source from my current metacity version (2.34.1) and changed that row. After compiling (./configure && make) I ran checkinstall which generates a .deb file from the source (had to change the version a bit to match the current one exactly). But after installing and loging out and back in, I couldn't load Gnome Classic. I get the error Failed to load session gnome-fallback. I could reinstall the old metacity which was still saved in /var/cache/apt/archives/, so everything is back where it was before. But I would like to mess around with metacity. Have I installed it correctly or did I forgot something? Are there any log files that I should check for solving this error? Thanks in advance!

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • Mobile Deals: the Consumer Wants You in Their Pocket

    - by Mike Stiles
    Mobile deals offer something we talk about a lot in social marketing, relevant content. If a consumer is already predisposed to liking your product and gets a timely deal for it that’s easy and convenient to use, not only do you score on the marketing side, it clearly generates some of that precious ROI that’s being demanded of social. First, a quick gut-check on the public’s adoption of mobile. Nielsen figures have 55.5% of US mobile owners using smartphones. If young people are indeed the future, you can count on the move to mobile exploding exponentially. Teens are the fastest growing segment of smartphone users, and 58% of them have one. But the largest demographic of smartphone users is 25-34 at 74%. That tells you a focus on mobile will yield great results now, and even better results straight ahead. So we can tell both from statistics and from all the faces around you that are buried in their smartphones this is where consumers are. But are they looking at you? Do you have a valid reason why they should? Everybody likes a good deal. BIA/Kelsey says US consumers will spend $3.6 billion this year for daily deals (the Groupons and LivingSocials of the world), up 87% from 2011. The report goes on to say over 26% of small businesses are either "very likely" or "extremely likely" to offer up a deal in the next 6 months. Retail Gazette reports 58% of consumers shop with coupons, a 40% increase in 4 years. When you consider that a deal can be the impetus for a real-world transaction, a first-time visit to a store, an online purchase, entry into a loyalty program, a social referral, a new fan or follower, etc., that 26% figure shows us there’s a lot of opportunity being left on the table by brands. The existing and emerging technologies behind mobile devices make the benefits of offering deals listed above possible. Take how mobile payment systems are being tied into deal delivery and loyalty programs. If it’s really easy to use a coupon or deal, it’ll get used. If it’s complicated, it’ll be passed over as “not worth it.” When you can pay with your mobile via technologies that connects store and user, you get the deal, you get the loyalty credit, you pay, and your receipt is uploaded, all in one easy swipe. Nothing to keep track of, nothing to lose or forget about. And the store “knows” you, so future offers will be based on your tastes. Consider the endgame. A customer who’s a fan of your belt buckle store’s Facebook Page is in one of your physical retail locations. They pull up your app, because they’ve gotten used to a loyalty deal being offered when they go to your store. Voila. A 10% discount active for the next 30 minutes. Maybe the app also surfaces social references to your brand made by friends so they can check out a buckle someone’s raving about. If they aren’t a fan of your Page or don’t have your app, perhaps they’ve opted into location-based deal services so you can still get them that 10% deal while they’re in the store. Or maybe they’ve walked in with a pre-purchased Groupon or Living Social voucher. They pay with one swipe, and you’ve learned about their buying preferences, credited their loyalty account and can encourage them to share a pic of their new buckle on social. Happy customer. Happy belt buckle company. All because the brand was willing to use the tech that’s available to meet consumers where they are, incentivize them, and show them how much they’re valued through rewards.

  • Recovering from an incorrectly deployed robots.txt?

    - by Doug T.
    We accidentally deployed a robots.txt from our development site that disallowed all crawling. This has caused traffic to dip dramatically, and google results to report: A description for this result is not available because of this site's robots.txt – learn more. We've since corrected the robots.txt about a 1.5 weeks ago, and you can see our robots.txt here. However, search results still report the same robots.txt message. The same appears to be true for Bing. We've taken the following action: Submitted site to be recrawled through google webmaster tools Submitted a site map to google (basically doing everything possible to say "Hey we're here! and we're crawlable!") Indeed a lot of crawl activity seems to be happening lately, but still no description is crawled. I noticed this question where the problem was specific to a 303 redirect back to a disallowed path. We are 301 redirecting to /blog, but crawling is allowed here. This redirect is due to a site redesign, wordpress paths for posts such as /2012/02/12/yadda yadda have been moved to /blog/2012/02/12. We 301 redirect to wordpress for /blog to keep our google juice. However, the sitemap we submitted might have /blog URLs. I'm not sure how much this matters. We clearly want to preserve google juice for URLs linked to us from before our redesign with the /2012/02/... URLs. So perhaps this has prevented some content from getting recrawled? How can we get all of our content, with links pointed to our site from pre-and-post redesign reporting descriptions? How can we resolve this problem and get our search traffic back to where it used to be?

  • Can't Move Windows to 2nd Monitor without Left Mouse and Cntl Key

    - by John C
    I have 2 very frustrating problems that maybe someone can help me with: I have 2 monitors (different sizes and resolutions) setup with the "Extended" monitor Win7 setup. My problem is this = I can not "move" a window from my Primary Monitor (larger and higher resolution on right side in front of me) to my Secondary 2nd monitor (smaller and lower resolution) with just selecting the title bar with the left mouse button and dragging it to the left. Windows 7 "snaps" it back to the left Primary Monitor when the window is physically in the 2nd window area as I'm holding the left mouse button. I can prevent this problem - by holding down the Cntl Key with the Left Mouse button, but this is extremely annoying to me. Also I typically "lose" focus if I try typing input on the 2nd monitor. Typing is erratic with regard to keystroke accuracy from my keyboard translated into input on the 2nd screen. No problem with typing input on the primary left monitor. I find this extremely annoying in Windows 7 and turning off the "snap" feature via the Control panel does NOT work for me. Win7 stubbornly refuses to move my selected window to my 2nd monitor without me "forcing" Win7 to do this with the Cntrl Key. Please tell me this is not a Win7 feature. Also on my system - Windows Key + Shift, Left arrow Key (pressed together) or the same combo with The Right arrow Key - don't do anything whatsoever. Widows Key with "+" however does maximize current window across both monitors, and I can "restore" it with Windows Key and "-" back to original monitor and size. I have tried various solutions including changing the resolutions of one or both of my monitors and sometimes "temporarily helps" but reverts back to the problem. Also if I swap the logical (not physical) layout so that I tell Win7 the monitors are setup in a reserved situation (Large monitor on the left, and small on the right) - this also sometimes helps for awhile - and is very strange and awkward to work with "backwards". But all of these solutions stop working. The only solution that consistently works for "moving" the screens is to hold the Cntrl Key down as I'm moving window with the left mouse selected on the title bar. Even that however, doesn't prevent the loss of typing focus for me on the 2nd monitor - while at the same time the typing on the 1st monitor is fine. Any help on moving my window screens from one monitor on my 2nd monitor without having to press the Cntrl key while holding down my left mouse button with be appreciated. Also any help on gaining typing "focus" into my 2nd screen with be helpful too. Thanks - John

  • loading splash screen takes priority over terminal or windows manager while running elsa

    - by schonjones
    I recently installed e17 and was trying to set up defaults to use elsa and ecomorph over the standard compiz as it constantly crashes since updating to 12.04. If elsa is installed the loading screen hangs and never loads to login, however i can get to a terminal or the e17 login instead of the standard gdm that usually shows up, within a second the screen goes back to the loading screen. I can still type and login as well as run commands in the terminal, but all I see is the loading screen. Switching between terminals i can confirm my commands before it switches back to the loading screen. If i remove elsa the loading screen hangs, but I can get to a terminal login and run lightdm to start my session with no problems. I have multiple DE installed and am unsure which loading screen is coming up. i think it's the KDE screen, grub comes up with a debian background if that helps. I'm not sure if i can switch the loading screen and resolve this issue or if i'm just going to have to scrap using elsa and get lightdm to load on boot again. Elsa would be my preference. I don't have the space to backup my files for a complete reinstall. Please help!

Steps I've tried. Complete shutdown Clear hiberfile.sys by disabling and enabling back Resetting my power settings. Causes I suspect: Had dual boot with BackTrack with Windows 8 GUI boot manager. It was fine until I reinstall BackTrack, bootmgr resetted and I'm in Ubuntu boot menu;.

  • How to stop OS X from switching input method (keyboard layout) automatically?

    - by adolf garlic
    After using the wireless keyboard that comes with the iMac, I have switched to a MS Ergo Natural 4000 one. Surprisingly I had to install extra software as OS X could not work out which keyboard I had. After which I went into sys prefs and set the main input method to be "British - Microsoft" first and "Swiss German" second (what the wireless keyboard is), on the "input sources" tab: However... OS X keeps resetting my input method back to Swiss German which is driving me bananas. I have the flag thingy top right so I can see when this changes. N.B. I have "input source options" set to "use the same one in all documents" which I am assuming means keep the language the same for anything running. It also flips back on the login page. Does anyone know how to fix this?

  • Automated Acceptance tests under specific contraints

    - by HH_
    This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

  • Tomato vs X-Wrt Wireless Router Firmware - which is better?

    - by wag2639
    A few years ago, I've switched over from DD-WRT to Tomato and I haven't looked back since. Before I did, I poked around with OpenWRT but found it too confusing or annoying to use (and I'm a CS major and setup and configured Linux servers using SSH). I'm probably not going back to DD-WRT because of all the controversy but I was wondering how X-Wrt is nowadays? From the screenshots, it looks a lot more featured packed than Tomato and that definitely has its appeal. Then again, simplicity has its advantages to. Any thoughts?

  • Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

    - by ProfessionalAmateur
    I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

    I am trying to setup a daily mirror of a mercurial repository - code.python.org in particular - within our local network, and serve that via Apache HTTPD. On the remote host that hosts apache, I did this: $ cd /var/www $ hg clone http://code.python.org/hg/trunk/ On my macbook, I ran: $ hg -v clone http://remote/trunk/ (falling back to static-http) abort: No such file or directory: http://remote/trunk/.hg/store/00manifest.i Google does not show any relevant result for this particular error. I remember back in those days being able to setup Bazaar mirrors by a simple clone. Doesn't Mercurial work like that? How do I setup a mirror that must further act like a clone URL?

  • Recover files after unsuccesfull partitioning

    - by arsan
    I wanted to install another Linux on my comp, so i tried to resize one of my NTFS partitions with Norton Partition Magic, but it didn't complete successfully and it showed some errors and said that the partition is not resized and that it's the same size like before, but when i rebooted my comp i couldn't open that partition anymore and also i am not able to mount it from my linux. So this is my question: I had very important data on that partition - can i recover it back ? I guess nothing's deleted it's just something messed up so it's not usable, but can i get it back ? Please if there's any possible way of doing it, reply to me, thank you.

  • Is there an open source clone of a game in the Total War Series?

    - by sinekonata
    I loved Shogun:Total War gameplay and then later on spent weeks re-enacting historical wars and battles with Europa Barbarorum. It's a mod for Rome:TW that focuses on historical accuracy in the peoples, units, sounds, visuals, everything from macro mechanics to actual battles (e.g. a lot more missiles). Since that time I kind of turned my back on Windows cause it sucks and use Linux cause Mac sucks even worse. So as I miss that game (Eur. Barb.) and consider it the most realistic RTS to date, I'd like to know if there are any free and open source alternatives to it because ever since I'm under linux, I became addicted to FOSS so I also turned my back on paying (even kickstarters) for closed source, pay to play games. I have found a clone/alternative for everyone of the best games like Minecraft, CSS, Natural Selection, TA/SupCom etc... It's kind of the last one I need. The Spring engine is amazing for example, is there another open source project of the source in current development? Or would Spring itself be enough (it certainly looks capable) to make it? Thanks in advance guys...

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 3)

    - by hinkmond
    In Part 2, I described what connections you need to make for this demo using a Hexbug Spider Robot, a Raspberry Pi, and Java SE Embedded for programming. Here are some photos of me doing the soldering. Software engineers should not be afraid of a little soldering work. It's all good. See: Skynet Big Data Demo (Part 2) One thing to watch out for when you open the remote is that there may be some glue covering the contact points. Make sure to use an Exacto knife or small screwdriver to scrape away any glue or non-conductive material covering each place where you need to solder. And after you are done with your soldering and you gave the solder enough time to cool, make sure all your connections are marked so that you know which wire goes where. Give each wire a very light tug to make sure it is soldered correctly and is making good contact. There are lots of videos on the Web to help you if this is your first time soldering. Check out Laday Ada's (from adafruit.com) links on how to solder if you need some additional help: http://www.ladyada.net/learn/soldering/thm.html If everything looks good, zip everything back up and meet back here for how to connect these wires to your Raspberry Pi. That will be it for the hardware part of this project. See, that wasn't so bad. Hinkmond

    I had recently moved all the content on my website from being in the www.mysite.com/shop directory to being in the root directory. This means that I needed to redirect any request to visit a page with the /shop directory back to the same page in the root directory eg. www.mysite.com/shop/categories/washroom to www.mysite.com/categories/washroom This needed to happen with all pages in my site that were previously using the /shop directory. I was given a solution on here which was: RedirectMatch (^/shop/)(.*) http://www.mysite.com/$2 and it works perfectly however now I have had to switch back to using our old version of our software which is located at the /shop directory so I need the complete opposite redirect now eg. www.mysite.com/categories/washroom to www.mysite.com/shop/categories/washroom Can anyone help me please?
