  • Laptop hardware recommendations for multi-platform development

    - by iama
    I am thinking of buying a laptop with the following configuration - Intel core 2 duo(or I3-330M)/ 4GB RAM/300+ GB 7200 RPM. I would like to be able to run two server VMs on this laptop with Win2K8 and Ubuntu (preferably 64 bit editions). Windows 7 will be the Host OS since that is the one that ships with the laptop. I am thinking of using VMWare player to run the two server OSs. Is this laptop good enough to run the two VMs side by side or do I need to go for a better configuration? Any suggestions? Thanks.

  • hardware leasing vs purchase

    - by musoNic80
    I'm wanting to get a new laptop and desktop. I'm self-employed and so both bits of kit are primarily for business use. I've been looking into leasing both computers as an alternative to purchasing outright. Does anyone have any experience of this? I'm UK based and have found a company called hardsoft which seem to offer a good service. I'm particularly attracted by the upgrade after 18 months option and the fact that the machines are under warranty for the lift of the lease. I'd be really grateful for general thoughts, especially if there are any UK users or hardsoft clients.

  • Hardware profiling [closed]

    - by mgroves
    I'd like to upgrade my computer so that it's faster when editing/rendering video. I'm thinking of first getting a faster hard drive, but I'd like to be able to run some sort of profiling software to tell me what the bottleneck is when rendering video. Any suggestions about software that can do this for preferably Windows XP and preferably for free?

  • Which hardware changes require operating system reinstallation?

    - by Mark
    I'm about to upgrade my computer but might keep some parts. Just wandering what I would have to keep to prevent me having to reinstall my OSs, at the moment I have a dual boot setup with ubuntu and windows 7. I'm pretty sure you can't just take your hard drive with the OS on it and put it into a different box and keep going (can you?) but I know you can change the graphics cards, secondary hard drives and ram with out a problem. So what is it that you can't change? The CPU? Motherboard? Thanks for any replies

  • Hardware needs for video conversion server

    - by artaxerxe
    I would need to build a Linux server that will have as its main task to perform the video conversion. For video conversion, the most likely I will use FFMpeg tool. Question: Can anyone tell me if for improving this automated video conversion a video card will improve the process or not? The idea is that I will get movies at a very high quality that I will need to be converted in formats available for different devices (iPhone, iPad, etc.). That conversion will be performed through a CLI (command line interface). I will need that conversion to be done in the least time possible (ok, that's a kind of saying, not an absolutely specified short time).

  • Lock System when certain hardware is removed

    - by er4z0r
    Hi all, I am working at a company where you are suppused to lock your screen whenever you leave your desk alone for a few minutes. Now I wondered if there is a nifty little tool that would lock my screen once a certain device is removed from the system. The ideal thing would of course be to have a short-range transmitter that causes the screen to be locked once it goes out of range. But for now I would also stick with removing a pen-drive from my laptop. I am pretty sure this is feasible. I just wan't to know if there are any preexistent projects.

  • Twitter 2 for Android crash every time I try uploading multi photos [closed]

    - by Hazz
    Hello, I'm using the new Twitter 2 on Android 2.1. Whenever I hit the button which enables me to upload multiple photos in a single tweet, I always get the error "The application Camera (process com.sonyericsson.camera) has stopped unexpectidly.

  • Hardware freeze during disk activity

    - by Thomi
    I built myself a linux-based NAS. It has several drives of various sizes and ages in an LVM configuration, with 800GB or so of data. The data is served using a simple samba server. This was working flawlessly, but after physically moving it, it has developed a strange fault: Whenever I do something on the server to cause disk activity, the entire machine freezes hard. This has the effect of killing any open network connections to the box, and generally making it useless. If I leave the machine for a few minutes it seems to come right again, but obviously this isn't really a solution. There are no error or warning messages in syslog, or the kernel logs. If I power the machine on, and leave it, it runs for several days without locking up. After that time I stopped testing. It doesn't freeze instantly - obviously it doesn't freeze while booting, and I can normally log in via SSH and start poking around in a few log files for a couple of minutes before it dies. My question is: What diagnostic tests can I run to determine the casuse?

  • Windows 7 Reinstalling Hardware - How...?

    - by Ative
    I wanted to install a new driver for my Wireless Network Card but Windows 7 reported the driver was up to date. So I decided to uninstall the driver. That seemed to do more than I expected... My WiFi card no longer shows up on the computer. Nothing in Device Manager. I have no idea how to get it back. How can I get Windows to find the device? :/

  • How to troubleshoot a hardware problem on linux?

    - by Jack
    Just to note I am not having a problem at the moment, but have had previously so it sparked my curiosity... When a computer locks up suddenly to so caps lock flashes incessantly and the only possibility to restart....how do you troubleshoot what is causing it? On Windows there would be some errors in the event log...on Linux it seems there is no opportunity for anything to be written to the log, making it hard to troubleshoot... In this case, how would you troubleshoot the problem through linux?

  • Hardware issue, bsod with windows xp irq and strange messages with ubuntu

    - by JP Hellemons
    I have an old Acer T160 and it used to run Windows XP. But I keep getting random BSOD's. I keep seeing IRQ conflicts. I tried to run ubuntu, which runs and keeps running. But sometimes is not responding. Also there are these popups at ubuntu 12.04 that my network cable (which is onboard) is unplugged. But I have no cable in it! and have an usb dongle for wifi. which also seems unstable. have to (auto)reconnect sometimes. So my question is: is it my mobo, power supply or something else? FYI: I had an dvd-rw station which did not open properly, so unplugged the ata and power, als removed the second harddrive. now only have sata harddrive. also removed the extra video card (ati sapphire x1600 pro) so use only onboard video now and still have these issues. EDIT Update: will try with a new PSU (power supply unit of 400watt) the old (factory) one was 300watt. and will use a usb drive which has 12.04 ubuntu on it (made with unetbootin) to format everything and re-install ubuntu. (so also delete mbr partition) will update the day after tomorrow.

  • hardware: delay and distinct 'click' before hard drive access

    - by matt lohkamp
    I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

  • Choosing hardware for Flash Media Server

    - by minaev
    Having read the answers in this discussion, I still would like to come up with the same question: What should I buy to run Flash Media Interactive Server 3.5? I just have slightly different boundary conditions. We plan to serve video to ca. 1,000 users simultaneously. It will be live stream, so the server will receive the stream in HD (1280x720), cache it, reformat to various other resolutions and send it to users. OS of choice is Linux, but if you say it should MS-DOS, so it will be... What would be a decent server for this task?

  • Suppliers for revision-controlled hardware, long-life motherboards?

    - by jacobsee
    Has anyone had good experience with suppliers of industrial computers, specifically 'long-life, revision-controlled' motherboards? I'm found a couple of likely candidates including ITOX, BCM, and DuroPC but haven't been able to find much in the way of independent review. I'm currently using off the shelf motherboards for an industrial data-acquisition system and am trying to eliminate the problem of rapid turnover/obsolescence of motherboards.

  • Minecraft server hosting hardware specifications [on hold]

    - by Andrew Wright
    I am planning on purchasing a server to rent off Minecraft game servers, largely to friends. I am planning on purchasing a 128GB RAM server to save on colocation costs (as I am likely to need more than 32GB and would have to rent 2U of space...) I am hoping for some advice about the processing power needed to deal with this level of RAM. The servers will be run in a shared environment on linux in a VM to make backups easier. The server I have in mind is dual CPU. I have been considering at the low end dual Xeon E5-2609V2 Quad-Core 2.5Ghz, and at the high end dual Xeon E5-2650V2 Eight-Core 2.6Ghz. The difference between these is 6.4 GT/s and 8 GT/s and £3000 for the lower spec server, £4300 for the higher spec. I was hoping I could get advice about whether it is worth paying for the extra/higher speed processor or if I would be wasting my money? Thank you for any help - I appreciate that this is not directly related to professional system administration.

  • MP3 Decoding on Android

    - by Rob Szumlakowski
    Hi. We're implementing a program for Android phones that plays audio streamed from the internet. Here's approximately what we do: Download a custom encrypted format. Decrypt to get chunks of regular MP3 data. Decode MP3 data to raw PCM data in a memory buffer. Pipe the raw PCM data to an AudioTrack Our target devices so far are Droid and Nexus One. Everything works great on Nexus One, but the MP3 decode is too slow on Droid. The audio playback starts to skip if we put the Droid under load. We are not permitted to decode the MP3 data to SD card, but I know that's not our problem anyways. We didn't write our own MP3 decoder, but used MPADEC (http://sourceforge.net/projects/mpadec/). It's free and was easy to integrate with our program. We compile it with the NDK. After exhaustive analysis with various profiling tools, we're convinced that it's this decoder that is falling behind. Here's the options we're thinking about: Find another MP3 decoder that we can compile with the Android NDK. This MP3 decoder would have to be either optimized to run on mobile ARM devices or maybe use integer-only math or some other optimizations to increase performance. Since the built-in Android MediaPlayer service will take URLs, we might be able to implement a tiny HTTP server in our program and serve the MediaPlayer with the decrypted MP3s. That way we can take advantage of the built-in MP3 decoder. Get access to the built-in MP3 decoder through the NDK. I don't know if this is possible. Does anyone have any suggestions on what we can do to speed up our MP3 decoding? -- Rob Sz

  • Android Custom Dialog NullPointerException

    - by Kyle Hughes
    I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

  • Android how to make button text bold when pressed or focussed

    - by stealthcopter
    I want to change the text inside a button to be bold when the button is highlighted or pressed. I currently use a xml file to define the button and use the XML to change how it looks when pressed but I would like to do this without using an image. <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/reset_hover" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/reset_hover" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/reset_hover" /> <item android:drawable="@drawable/reset" /> </selector> I tried using something like the following, but it doesn't seem to ever get called. final Button btn_reset = (Button) findViewById(R.id.btn_reset); btn_reset.setOnClickListener(this); btn_reset.setOn(new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus){btn_reset.setTypeface(null, Typeface.BOLD);} else{btn_reset.setTypeface(null, Typeface.NORMAL);} } });
