  • Recommendations for SSD for server and database use?

    - by Tony_Henrich
    SSDs are a new technology and they are constantly improving. A lot of the posts here were posted in 2009 when SSDs where less mature and not as fast. What was recommend back then is probably out of date today because of better options. The SSD is used to hold SQL Server databases. Size is probably 128G. The database is used with a CMS and web server so web pages need to get their data and render as fast as possible. Which modern SSD is recommended for such a use? Is there an SSD better than Intel X-25 E/M in terms of performance/cost? (I am also evaluating cost between : RAM + UPS (semi persistent) vs SSD for same amount of gigabytes. No RAID is involved)

  • OpenVPN and brouting issue

    - by JavierMartinz
    I have a Guest XEN Machine in which I want to connect by OpenVPN to other network. But I have this problem: when I want to connect to that OpenVPN I get a lot of TLS handshake errors because I think that the packages did not come rightly. When, at the end, the guest machine achieve to connect (after several tries) I can't ping the other machines of the OpenVPN network. Except sometimes, where if I ping 20 times MAYBE i get ping-answer in 1-2 times. I think that this problem is related about how the HOST Xen machine 'filters' the packages to the bridge. I mean, I think that all the outgoing guest machines packages are good but the incoming traffic to the guests is not recognized well. How could I detect/solve the problem? Im using Debian Linux in both machines

  • SharePoint (2010) - Can't delete Service Application

    - by Chris W
    The search service application in our farm went bonkers complaining that it couldn't connect to itself. After multiple people fiddling to try and fix it we've ended up with two search application. The new one, which is working perfectly, and the original one which is very unhappy. I've tried deleting the original Search App in Central Admin but it just won't go - it sits on the screen saying "Processing" but it never completes regardless of how long it is left. There's lot's happening in the logs but I can't really decipher exactly why this isn't working. Things are working fine within the farm but I'd ideally like to clean up this old application if possible. Are there any other options like deleting it with stsadm? I've had a dig but can't seem to find the commands to enumerate the service applications and then delete the correct one.

  • Basic SDL2 Code which "Stop working" when calling SDL_Quit() [migrated]

    - by Rivten
    So I got into SDL2 with C++ quite recently and I did this very simple code : int main(int argc, char** argv) { SDL_Event *event; bool done = false; if(SDL_Init(SDL_INIT_VIDEO) != 0) { std::cerr << "Problèmes pour initialiser la SDL : " << SDL_GetError() << std::endl; return 1; } SDL_Window *window = 0; window = SDL_CreateWindow("Mopion", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN); if(window == 0) { done = true; } while(!done) { while(SDL_PollEvent(event)) { switch(event->type) { case SDL_QUIT: done = true; break; case SDL_KEYUP: if(event->key.keysym.sym == SDLK_q) { done = true; } break; default: break; } } } SDL_DestroyWindow(window); SDL_Quit(); return 0; } While that code executes at first quite well, when I hit the "Q" key, the window closes but I got a Windows Error Window saying that "My program stopped working." which is not very convenient. Using the debugger, I found that everything is fine until SDL_Quit() is called. Anyone has any idea why this is going on ? Thanks a lot !

  • How you choose your first job as a programmer? [on hold]

    - by sliter
    For Brief I am a recently graduated CS student. I am looking for a job these days, but I have no idea what kind of software development jobs I like(embedded system,web development or else...). And I am looking for your advice. Here is a little more While I was a student, I had an one year internship experience as a system engineer in a semi-conductor company where I wrote Linux driver, tuned system performance, etc.. I was happy about this experience as it allowed me to deepen my understanding of the operating system and different low level things. And I thought "Em, I will continue in the embedded area after I graduate". At the end of my study, I am doing an another internship in web development, both front-end and back-end. And I also enjoys a lot the process of learning new things and making it work (Backbone, Node, socketio, etc..). Now, when I am looking for a software development position, I do not know what to apply! All I know is that I want a job which allows me to keep up with the trends instead of repeating. But besides this, I've no idea what specific type of job I want to do. Turn back to embedded system? Continue with web development? Change to other promising areas(data mining)? All these development positions makes no big difference to me. But I think this is not good and I need some criteria at choosing. So I am looking for advice and I would really appreciate if you can share your experience.

  • No Audio Output Device is installed

    - by mabho
    Hi, this is an intermitent problem in my Sony Vaio model PCG-5K1L. I keep on getting a "No Audio Output Device is installed" when hovering my loudspeaker icon in Windows Vista. I have tried System Device Manager Sound Realtek High Definition Album Update Driver Software. The update process went through, but nothing happens. Still Vista does not seem to recognize my audio software. The strange part is that out of nothing my sound card can resume working to stop again hours later... If someone has any clues to solve this, please, help. Thanks a lot.

  • Forensics on Virtual Private servers [closed]

    - by intiha
    So these days with talks about having hacked machines being used for malware spreading and botnet C&C, the one issue that is not clear to me is what do the law enforcement agencies do once they have identified a server as being a source or controller of attack/APT and that server is a VPS on my cluster/datacenter? Do they take away the entire machine? This option seems to have a lot of collateral damage associated with it, so I am not sure what happens and what are the best practices for system admins for helping law enforcement with its job while keeping our jobs!

  • Windows W8, L8 and now H8

    - by raccoon_tim
    Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

  • For a particular domain, how can I cache its JSON responses locally?

    - by Chris
    I'm coding the frontend of a web app that uses XHR to grab JSON data from a 3rd party. The 3rd party service is slow and because of its API design, we need to make a LOT of API requests every time I refresh the page to test some new code. It's making the development loop painful. The requests are GETs, POSTs and PUTs even though I'm pretty sure none of the requests are changing state. I want to go to localhost for the JSON rather than to this 3rd party API - simply to make my development process faster.

  • Good resources for learning modern OpenGL (3.0 or later)?

    - by MatterGoal
    I stumble upon the search of a good resource to start with OpenGL (3.0 or later) . Well, I found a lot of books but none of them can be considered a good resource! Here two examples: OpenGL Programming Guide (7th edition) http://www.amazon.com/exec/obidos/ASIN/0321552628/khongrou-20 This is FULL of deprecated material! Almost every chapters begin with a note about that. OpenGL Superbible (5th Edition) http://www.amazon.com/exec/obidos/ASIN/0321712617/khongrou-20 This book uses a library created by the author to explain the main arguments, hiding what you want to learn! I don't want to learn how to use your library! I want to learn OpenGL! I hope that you understand this is not the same question like "hey I'm not able to use Google... tell me how to learn OpenGL". I've just finished a full and deep search but I can't find a good and complete resource to learn the "new" OpenGL avoiding deprecated topics. Can someone heading me in the right direction? I know C++ and I have 10 years of experience in development... where I can find a good resource?! I want to spend time on it and I want to learn deeply. (please feel free to edit my question, my English is terrible!)

  • Unidentified Window OnStartup

    - by CMP
    Every time I start up windows vista lately, I see a random floating window. It is a tiny little window with no title, and only the resize, maximize and restore buttons. I'd post an image, but I don't have reputation here yet. I can close it, and it does indeed go away, but I would love to figure out what it is and stop it from popping up at all. I used Autohotkey's window spy on it and all I learned is that it is a swing window, which doesn't help me out a whole lot. Is there a good way to identify which process it belongs to and figure out how to kill it?

  • what will EcmaScript 6 bring to the table for us

    - by user697296
    Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

  • How to Activate wifi in Toshiba Satellite C655?

    - by user4106
    I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

  • Best practices for FQDN for standalone domain (is a two part domain.tld okay?)

    - by birchbark
    I've searched quite a bit and can't seem to find a straight, modern answer on this. If I am hosting a domain, say, mydomain.com, on a machine which is going to solely be used for that domain, and there are no subdomains, is there a real, practical reason besides compliance to create an arbitrary hostname (i.e. myhost) just in order to have a three-part FQDN (myhost.mydomain.com) to satisfy some sort of RFC or convention that's expected. This seems to make a lot of undue complexities from my perspective, and I'm not sure if there's an advantage to this or if it's just a hold-over from a time where all web resources came from a subdomains such as www and ftp which may need to scale to separate machines. I don't use www on my domain, either, which is ill-advised for all I know from an administrators perspective (though removing it is the norm from a designer's perspective)...

  • FreeNAS 8 and ext fs

    - by oraclecow
    i'm trying out freenas8 for my personal NAS, i have lots of data that was in an ubuntu server, but somehow i never got the file sharing right. on freenas things just worked. i installed on usb, tried sharing the windows disk, and i can see it on my windows 7 right away. my question is, is it ok to use ext4 fs from my ubuntu instalation ? i only saw zfs, ufs, ntfs, and ext2 option to import, i havent plugged in the disks yet, but im wondering the consequences, like if it asked to format like in windows to use. i can format the disks of course, but 5-6 TB of data juggling and reformatting is a lot of work, unnecessary work i think, does the zfs worth the trouble of formatting everything ? since i'm thinking to use it if i have to format it anyway and zfs looks more interesting than ext2.

  • Open source monitoring tool without sending data to "Their Server"

    - by hangu
    I trying to use open source server monitoring tool. I know there are a lot, but I couldn't find what I need.. the basic process of monitoring tool I used to use before was, 1) Install agent in my server which I want to monitor 2) The agent send data to "their server" 3) I can check the health of my server through web browser presented by them. What I need is, avoiding "Step 2". Are there any monitoring tool that I can use? I have Windows 2008 and Linux servers simple feature will be enough like (CPU, Memory, Network..) Thank you

  • What makes a theme "Premium"

    - by Sinthia V
    I have a lot of time invested in creating Wordpress templates. I want to release combinations of these templates along with different styles and Fancy Front pages as "Premium Wordpress Themes". What I need to know is what does "Premium" mean? What do people expect of a GPL theme vs. a Premium theme? Are there features that are considered required to be premium? Are there features that are in demand but considered "exceptional" i.e. not part of every premium theme? How can I tell the difference? I have heard tounge-in-cheek answers that say that any theme that makes money is premium, but I mean to ask about what gives an outstanding theme it's quality. Why is it worth more? I am technically able to do many things, but as a lone developer with a family to feed, I can't afford to spend time on features that no one cares about. I have to try to isolate the things that people want. This is serious food and rent to me. How can I get this kind of info so I can make my project successful?

  • FeedDaemon and Tweetdeck not opening links in Chrome but opening in IE when IE is set default browser

    - by user2059078
    A while ago a Chrome version update failed and I ended up having a program called new_chrome.exe in the folder where chrome.exe used to be. I was very busy at that moment and I continued to work without bothering to try to fix the problem. Apparently recently another update came out and the new_chrome.exe is now gone, it was replaced by chrome.exe. Since the last upgrade happened two applications that I use a lot (not sure if others do the same) do now work anymore as they used to when I try to open links. These two apps are Tweetdek and Feedaemon. If I change the default browser to Internet Explorer they both open the links when I click on them I tried everything I could but it did not work: My Default programs look like this: and my set Default Programs looks like this: How can I fix this?

  • How can I stop Pages from bolding/italicizing ordered list item numbers/letters?

    - by donut
    I'm writing a long, technical document that uses a lot of ordered lists in Pages '09. Often when I bold or italicize the first bit of text I type for a list item it Pages applies the same styling to the letter or number of that list item. It's been doing this for the first 13 pages I've written and now I've found out that I need to undo that. Is there any place to change this behavior or easily fix existing list item numbers/letters that are styled? The only way I've found is to select the whole list item (all of its content) and removing teh styling (un-bolding and un-italicizing) and then going back in and re-applying my stylings to its content. Definitely not ideal.

  • Too Many ESTABLISHED connection from a single IP address in Apache

    - by ananthan
    netstat -ntp |grep 80 shows too many ESTABLISHED connection from single IP address. Around 300 of them and it is not an attack and user is using a 2G connection to access Apache. This is the case with other 2G connections also. As a result of this Apache is running out of children. Earlier it was showing too many close_wait and after enabling tcp_tw_reuse and tcp_tw-recycle there is not much close_wait but the number of ESTABLISHED connections increased. We are using Ubuntu 11.04 having 48 GB ram keepalive On keepalive timeout 10 max clients 800 max-request-perchild 4000 timeout 300 I have set syn_ack to 1 and syn_retries to 2. On wifi there is no such issue. Connections are closing properly, but with 2G connections Apache is running out of children and too many ESTABLISHED connection. also i have tried setting timeout from default 300 to 30,but since our project is image hosting for mobile phones,clients couldn't upload images properly as they are getting frequent time out.Also there were a lot of 408 messages so changed it to the default 300

  • rsync generates very much traffic

    - by user109459
    I use rsync for backing up one of my servers with 4GB of files. When I now try to transfer these files the traffic for the files isn't the estimated 4GB. It is a lot higher. It's about 60GB. I also checked the traffic on my server, backup server and router and all three say that there was a traffic of 60GB. But at the end rsync says that it only has transfered 4GB. Another problem is that I can't debugg it because the problem occures randomly.

  • Network(ing) to the Limit

    - by Oracle OpenWorld Blog Team
     By Karen Shamban While Oracle OpenWorld attendees are networking, there's an Oracle Global IT team that builds and maintains the massive networks that help run the show. The objective? To keep things running as seamlessly and smoothly as possible, constantly evaluate priorities, mitigate risk, and be ready for whatever might happen -- because things do happen when there are 50,000 plus attendees, tens of thousands of devices, unexpected requirements, and a constant flow of up-to-the-minute information. Here's just some of what it takes to keep the conference going, network style: 100 Oracle network, voice, and desktop engineers; security, risk management, and other IT experts, who come in from 17 countries  1000+ network switches 300+ miles of copper and fiber 485 wireless access points 2,500 wired laptops 300 VoIP phones And just where are all these networks and devices deployed? This is what the team had to build and manage: Moscone North, South, and West, including: The keynote hall Oracle DEMOgrounds in the Exhibition Halls Hundreds of session rooms Connection Centers, Social Avenue, Lounges Registration The Howard Street Tent and Taylor Street Cafe tented venues Oracle Square (Union Square) Yerba Buena Gardens Masonic Auditorium Sessions and demos at 8 hotel venues That's a whole lot of networking going on. And here's the kicker: the team has only 4 days to bring get it all up and running across these many venues, and exactly 12 hours to take it all down once the show ends. The Global IT team puts in the equivalent of 152 24-hour days for set-up, 227 24-hour days of support during the conferences, and then tears it all down in about 20 24-hour days. And in case you were wondering, the planning for next year's Oracle OpenWorld starts ... next week. No rest for the weary.  Now THAT's networking!  So hats off to the Global IT team -- the job ain't easy, but somebody's got to do it, and they do it remarkably well.

  • Is it bad to put your computer in sleep mode every time?

    - by Ivo Flipse
    Often I have a lot of stuff open and don't feel like shutting down my laptop, so I just use sleep mode when I'm transferring it. But I have no idea if this might have any disadvantages. So my question is: is it bad to put your computer in sleep mode every time? Things I'm wondering: Should I turn off my computer every once in a while? Will continuous use of sleep mode slow down my system in any way? Are there any bad side effects (in the long term)? Any thoughts? FYI I'm using Windows 7 on a laptop

  • How to work with bookmarks in Word without naming them?

    - by deepc
    I am working in a large Word 2007 document and need bookmarks to remember editing positions. I know I can manage bookmarks with shift+ctrl+F5 but that's cumbersome because I am used to do this a lot faster in the Delphi editor. There I create a bookmark with ctrl+shift+0..9 and jump to the bookmark with ctrl+0..9. In this way I have 10 quick bookmarks. I do not have to name them, I do not have to pick them from a dialog (because there is not even a dialog prompting me for a selection). Is something similar possible in Word, or has anybody made a macro for that purpose? Thanks.
