• Server Requirement and Cost for an android Application [duplicate]

  - by CagkanToptas

  This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers Can you help me with my capacity planning? 2 answers I am working on a project which is an android application. For my project proposal, I need to calculate what is my server requirements to overcome the traffic I explained below? and if possible, I want to learn what is approximate cost of such server? I am giving the maximum expected values for calculation : -Database will be in mysql (Average service time of DB is 100-110ms in my computer[i5,4GB Ram]) -A request will transfer 150Kb data for each request on average. -Total user count : 1m -Active user count : 50k -Estimated request/sec for 1 active user : 0.06 -Total expected request/second to the server = ~5000 I am expecting this traffic between 20:00-1:00 everyday and then this values will decrease to 1/10 rest of the day. Is there any solution to this? [e.g increasing server capacity in a specific time period everyday to reduce cost]

• Failing Seagate HDD - Not Recognised

  - by thefragileomen

  I am having a look at a friend's computer which contains a 500GB Seagate HDD. Unfortunately the HDD is not recognised by the BIOS menu and it beeps 11 times upon powerup. I've moved the HDD to another laptop but the problem remains. I've downloaded SeaTools for DOS (Seagate's Diagnostic tool) but unfortunately to no avail and the disc remains unseen when using this DOS boot disc. The HDD is only 6 months old so I'm very surprised at this but it appears a common problem with Seagate 2.5" HDDs as well as other HDDs manufactured by Seagate. I intend to try it in an external caddy on Thursday when back in work and also through a forensic writeblocker but just wondering if anyone has any other suggestions? I am of the opinion it is some chip on the HDD board which prevents it spinning due to a fault. If so, I've lost to deactivate this just so I can simply recover the data on the drive and start with a new disc. Thanks

• Powershell window preventing shutdown

  - by FrinkTheBrave

  If I have a PowerShell window (at the PS command prompt) on display it prevents the computer shutting down. i.e. if I open a powershell window and then try to shutdown the server, I get the End Program popup saying Windows cannot end this program I get the same result if I start the powershell from the start menu, from a cmd prompt and from a shortcut with -NoExit specified. Any ideas how I can get shutdown to automatically close a powershell window (if it is at the PS prompt) in the same way as it would for a CMD window? Alternatively, is it possible for PowerShell to detect when a shutdown has been initiated and therefore close itself?

• Where do I find a free (open source preferably) VNC management tool?

  - by thenior

  Hello, I am trying to get remote internal setup for our business. Basically, I just want to remote desktop into any computer on the network. I don't want to use LogMein, because I only want it to be internal for security. Basically, I am looking for a way to just install VNC clients on all the machines, and on my machine have centralized manager for all the machines that are connected to it. Doesn't have to VNC - just needs to work and be free. All systems running Win 7 64bit

• nautilus will not start, no right click menu, apps will not run due to 64bit libicui18n.so.48 overwritten with 32bit, ubuntu 12.04

  - by Dewb

  yeah so i broke my system trying to install support for 32bit apps. Somehow the 32bit set of libicu*.so.48 files replaced my 64bit files and now nothing works. I know what the problem is and how to fix it , what i need is some help. I need some kind soul running a 64bit install of Ubuntu 12.04 to simply go into their /usr/lib dir and copy the files that have the form libicu*.so.48* (8 of them i think, maybe 16 i dunno how many there is supposed to be since they were overwritten). Anyway if you could put those files in an archive, zip or tar preferred and then email/share the link. I was able to get these files installed but they're from the latest edition of fedora and while i can now use my computer , it's not that stable things don't start right smoothly every time like they used to .... and well its a simple ordeal to put things back the way they were if someone wouldn't mind helping out. also any help setting up the libraries related to 32bit apps would be great as well as i apparently screwed that up royally. Thanks for any help or advice

• Run a service after networking is ready on Ubuntu?

  - by TK Kocheran

  I'm trying to start a service that depends on networking being started, whenever the computer is rebooted. I have a few questions: Is this easily possible from an /etc/init.d script? I have tried creating a script here (conforming to the standards), but I'm really doubtful that it's even running on boot, let alone working. When I test it manually, it works. I've seen the new Upstart service, but as far as how that actually works, I'm completely in the dark. How can I make a script that runs on boot which runs after networking has been started? If I could run it after connected to wireless network, even better :)

• Windows 7 - saved wifi access points disappear from list

  - by KáGé

  I'm having a weird issue with Windows 7 x64: I'm moving my notebook between two locations weekly, at each I have a wifi router. They both have hidden SSID-s, which are different. If I save one, the other one gets deleted from the list, as if overwritten, so I always have to retype the SSID and password, if I want to connect after moving my computer. At first I tought the problem was caused by both routers having the same password, but after I changed one (suffixed it with "_2") it persisted. What can I do about this? Thanks.

• Mouse selects everything on its own

  - by meneer

  I have a strange problem that my mouse keeps selecting everything I point to. For example, if I open Rhythmbox, then at the top of the screen there is a text which says which song is playing. If I move my mouse over this text, then it will select this text; but I am not clicking. This behaviour does not happen in all programs. For example in Firefox I have no problem at all. Maybe it is Gtk related? Nautilus also behaves strangely; I cannot open files by clicking on them, I have to select and make a box around the file and then press enter to open it. If I click, then nothing happens. Similar problems also happen with other Gtk software. I think the problem might be related to touchscreen issues (I have a touchscreen). I run Gnome 3 on Ubuntu 12.04. I have a HP touchsmart 610 desktop computer. Any help is greatly appreciated. UPDATE: I just did a fresh reinstall, and I am 90% certain that it is related to the touchscreen drivers. Here is what happens when I reinstall. At first boot, so exactly after install, everything works fine, except the touchscreen: The touchscreen does not respond. I update ubuntu, because I installed from an old CD (CD with ub. 12.04). Then on next reboot I have touchscreen working , but the working touchscreen comes together with the mouse selecting everything on its own. SECOND QUESTION: Would anybody know how I could figure out what those touchscreen drivers are (so that I can disable them) ?

• Having an issue with Java/ minecraft (Windows 7 64bit)

  - by MetroGnome

  I have had issues with java on my computer for a while. First of all, java has never worked on Google Chrome or Firefox, Only IE. Whenever I need to use Java, I use IE. Now, I just tried to play minecraft the other week and I receive the error "fatal error (1)" and get a black screen (this is on the online free version). Now, I searched for java and found that I have Java 32 bit. I cannot uninstall it on Revo uninstaller or Windows uninstaller. What should I do?

• Windows 8.1 keeps prompting for Network Share Credentials after every log on or restart

  - by Peret del Trunfa

  I have a Network drive Shared in a Workgroup with 3 clients. Two clients with Windows 7 have persistent connections to the Share. No issues with those two. My windows 8.1 client keeps prompting for credentials at every restart / log on. I spent hours looking around for a solution: I have stored cred in cred manager, and tried every possible combination (WORKGROUP\user , COMPUTERNAME\user, user, .. and so on). I have changed NT and NTLM negotiation in policy manager. I've compared the settings under GPO network security with a working win 7 computer, everything is pretty much the same. -I've captured Wireshark to see SMB negotiation process, honestly I see the messages flowing around, and the share sending AUTH DENIED.. which means is how the 8.1 client formats the request.... that makes the share reject it.. Now I still don't really know why. Any ideas would be appreciated.

• Ubuntu 11.10 very slow compared to Windows

  - by Patrick

  I'm new to Ubuntu/linux. Since my PC is very old and not very fast with Windows 7, I decided to give Ubuntu a try, so I downloaded and installed Ubuntu 11.10 today. When I first started it, I had bad 800x600 resolution and it was very slow and annoying. So I installed a driver for my graphic card and now everything looks very nice (1280x1024).But I think it's still far slower than Windows 7. I tried to run in Ubuntu like a few people suggested on the forum but if I log in I get a black screen saying something like "this video mode cannot be displayed". I get that same screen when booting Ubuntu btw, but after about 15 seconds it disappears and just starts Ubuntu. I also installed other drivers for my graphic card but everything stayed the same. I noticed that i.e. when I open Firefox or system settings it takes about 5 seconds till it opens (while Windows 7 takes under 1 second to start i.e. Chrome) and when I do this my CPU usage gets to 100% for a short time. Computer specs: Memory: 2GB RAM Processor: Intel Pentium 4 2.8GHz Graphics Card: Nvidia GeForce 6800 400MHz. I read on various forums that 11.04 works flawless on many PCs, where 11.10 is very slow. Should I install 11.04 or could anybody help me with this problem?

• sql server: losing identity column on export/import

  - by Y.G.J

  Recently I started dealing with SQL Server, my previous experience was in MS-Access. When I'm doing an import/export of a db, from the server to my computer or even in the server, all column with primary key loose the key. Identity is set to false and even bit is not set to the default. How can I can I use an import/export job to make an exact copy of the db and its data? I don't want to have to perform a backup and restore every time I want the same db somewhere else, for another project, etc. I have read about "edit mapping" and the checkbox but that did not helped with the identity specification... and what about the primary key of the tables and the rest of the things?

• Sennheiser PC360 Microphone Suddenly Stopped Working

  - by Michaelwm

  Just recently, my Sennheiser PC360's microphone stopped working. Yesterday Night, it was working 100% fine. Muting correctly, un-muting, volume boosting, etc. I woke up this morning, and got into a skype call (After not changing a single setting on my computer), and it wasn't working. I tried mumble, and it didn't work there either. After that, I checked my sound devices and found out it was plugged in, but not responding to my voice. I unplugged the headset, and it correctly showed that it was unplugged. So, a quick run-down: Sennheiser PC360 Headset suddenly stops working after a few hours of sleep. Software is up to date I can hear the mute sound when I raise and lower the microphone arm Windows Sound Device Manager shows that it is plugged in Unplugging the headset correctly shows it is unplugged Windows Sound Device Manager shows that the microphone isn't receiving any input

• Set one homepage for all browsers simultaneously

  - by MorganTiley

  For testing purposes, I would like to set the homepage of all browsers installed on my computer — Internet Explorer, Chrome, Firefox and Safari — to the same page. I'd like to do this all at the same time. I imagine that there's an application that has an input box for the URL I want to use as homepage and an OK button to set it in all browsers. Where can I get a utility or script that can do this?

• How do i keep a newly started program from taking focus?

  - by Jugglingnutcase

  Say i'm coding in emacs and want to start up a music program. Because it takes too long to start up i go back to coding and type away. When the music application starts up, the focus is stolen (gasp! stolen!) away from emacs and goes to the music application, often mid-thought. Is there any way to keep this from happening and have the newly started application not have focus until i see that it's up and ready to be used? Besides getting rid of my ADD of course. Or getting an impossibly fast computer that can keep up with my mind. i'm using a Windows XP system, but i will soon have a Windows 7 system, and i have Linux at home.

• How can I upgrade from Windows 8 x32 to x64 fastest & easiest?

  - by parkviewK

  I was upgrading the hardware in a family member's computer and purchased the Windows 8 upgrade for $40 from their website. Not thinking, after I installed it I realized I now have 32bit Windows on this 64bit capable machine. Did some research and it appears that the upgrade assistant just gives you whatever architecture you were uprgading from (windows 7 32bit). Question is, what is my best option here? I have already purchased a key, will this work on x64? I'm considering installing Windows 8 Preview x64 and upgrading from there, but not sure if that will work or if it will make me purchase it again.

• How to enable winhlp on Windows7 64bit?

  - by BGM

  Salvete! I just discovered that winhlp32.exe won't run on Windows7 64bit. I can't run the application, and I can't run hlp files either (but .chm files run fine). How do I make this work? I have downloaded the Microsoft fix here and restarted my computer, but to no avail. I can see the file winhlp32.exe in my c:\windows directory, but cannot run it. When I do run it, I get Windows' own "Help and Support" entitled, "Why can't I get Help from this program?" which sends me to the link above! How can I make it work?

• I want to easily switch accounts for Twitter - is there a Firefox/Chrome/IE plug-in to do this?

  - by Edelcom

  I have several Twitter accounts to which I post messages. One is a personal, one is a professional, and a couple for each software system I developed. Does any one know of a plug-in for one of the major web browses on Windows or program that allows me to easily login to multiple Twitter accounts and easily switch between them ? I now have the 4 major browsers installed on my computer , each with it's own Twitter account (with the password and login info saved), but I think there must be a better way. On a side note: it is getting harder and harder to know to which StackOverflow alike site a question must be posted. So I hope this question here is considered on-topic.

• Automatic profile load on boot

  - by AnthonyW

  Is there any way to configure a computer to login automatically at bootup and then IMMEDIATELY switch users? The purpose is to trigger the profile loading process for the assumed user so that when they go to login, their profile loads instantaneously. Yet, the immediate user switch means that the login password is still required before any actual use. A few of the attempts I have made require storing the password in plain-text for the system to use. Needless to say that is undesireable. I have been looking for this solution for years; if anyone knows of a better solution to skinning this cat I am all ears. EDIT: tsdiscon command will Lock the workstation.

• Starting Apache through XAMPP is not working

  - by nogamo

  I've checked the error logs for this particular problem and it seems no access can be made to port 80. (OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address [::]:80 Turning the Windows firewall off didn't work, so I'm a bit lost. All of this is running on my laptop so I don't have my own "server" per se but I was under the impression that this would work without the need for one independent of my own personal computer. How would I solve this?

• Was Windows 95 an Operating System?

  - by shantnu

  This question maybe a bit historical, but we didn't have Superuser at the time. Around 2000 when I was starting my Computer science degree, a subject was Operating systems. The teacher asked us to list a few OS. I said Windows 95. I was immediately shot down. Windows 95 wasn't on OS, as it used DOS to boot up. The actual OS was DOS, Win 95 was just a graphical wrapper around it. I pointed that all trade magazines called Win95 an OS, but was told that they were run by laymen, and as a professional, I should know better. DOS was the only OS from Microsoft, at least till Win2K came out later that year. So 12 years on, I'm still not sure. Could Win 95 be considered an OS?

• Re: # 47209 How to copy an Existing HD to a new one and have it be bootable?

  - by user281151

  Help please! My backup method of choice is to clone my "working" drive to another identical drive. I have 2 windows drives and I clone my working one to the other one once per month. No problem - each will boot if I select it. Now with the lack of future support for XP, I am getting familiar with Ubuntu 14.04 LTS. I have it on one drive and I have a second identical drive that I want to be able to clone it to once/month. Not as necessary to do this with Ubuntu as with windows, I know, but I'm anal. So I have followed #47209 MestreLion's procedure with just the two Ubuntu drives "on line". I.e., boot my "working" drive with Live CD, use Gparted to be sure I know what's what, open terminal and enter and execute the dd command, Go to bed till the clone is done, shut down the computer, disconnect the input/source drive, boot up using BIOS to select the remaining output drive. The drive starts fine but all is not OK. It puts up a screen that says I'm on a Guest Session and asks for a password. Well, for one thing I have my Ubuntu set up to start without a password being entered. I have one, of course, I put it in but it isn't accepted. I can't get by this Guest Session screen. I am fine, of course. I can disconnect this drive, hook up my "main" ubuntu drive and all the rest, and go on with my business. But I don't have the desired "emergency backup" drive working where I could jump on and use it immediately if I needed it. Can someone give me some guidance here?? What (else) do I need to do. Love Ubuntu but learning. Thanks, Wes.

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• When Typing on my mac the cursor moves/deletes/replaces text.

  - by David

  Help! I don't know what is happening, with my computer (Macbook Black OSX 1ha0.6.6) but recently whenever I am typing my cursor suddenly moves in the middle of my frase or paragraph, deleting text, replacing words or just closing applications. I don't know what might be the cause but it's driving me crazy. I have disabled typinator (which had worked fine for a couple of months) and looked through the keybindings in SystemPreferencesKeyboardKeyboard Shortcuts. But for have not been able to find any answers. It happens in all apps that require typing. Textmate, Chrome, FIrefox, Texedit, Mail. Does anybody know if there is a way I can review all keyboard shortcuts, to see if the issue lies there or any suggestions? Thanking you dearly Dave
