  • How to Browse Without a Trace with an Ubuntu Live CD

    - by Trevor Bekolay
    No matter how diligently you clear your cache and erase your history, web browsing leaves traces on your computer. If you need keep your browsing private, then an Ubuntu Live CD is the answer. The key to this trick is that the Live CD environment runs completely in RAM, so things like your cache, cookies, and history don’t get saved to a persistent storage location. On a hard drive, even deleted files can be recovered, but once a computer is turned off the data stored in RAM is unrecoverable. In addition, since the Ubuntu Live CD environment is the same no matter what computer you use it on, there’s very little identifying information that a website can use to track you! The first step is to either burn an Ubuntu Live CD, or prepare a non-persistent Ubuntu USB flash drive. Ubuntu treats non-persistent flash drives like CDs, so files will not be written to it, but if you’re paranoid, then using a physical CD ensures that nothing gets written to a storage device. Boot up from the CD or flash drive, and choose to Run Ubuntu from the CD or flash drive if prompted (for more detailed instructions on booting from a CD or USB drive, see this article, or our guide on booting from a flash drive even if your BIOS won’t let you). Once the graphical Ubuntu environment comes up, you can click on the Firefox icon at the top of the screen to start browsing. If your browsing requires Flash, then you can install it by clicking on System at the top-left of the screen, then Administration > Synaptic Package Manager. Click on Settings at the top of the Synaptic window, and then select Repositories. Add a check in the checkbox with the label ending in “multiverse”. Click Close. Click the Reload button in the main Synaptic window. The list of available packages will reload. When they’ve reloaded, type “restricted” in the Quick search box. Right-click on ubuntu-restricted-extras and select Mark for Installation. It will note a number of other packages that will be installed. This list includes audio and video codecs, so after installing these, you should be able to play downloaded movies and songs. Click Mark to accept the installation of these other packages. Once you return to the main Synaptic window, click the Apply button and go through the dialogs to finish the installation of Flash and the other useful packages. If you open up Firefox now, you’ll have no problems using websites that use Flash. When you’re done browsing and shut down or restart your computer, all traces of your web browsing will be gone. It’s a bit of work compared to just using a privacy-centric browser, but if it’s very important that your browsing leave no traces on your hard drive, an Ubuntu Live CD is your best bet.

  • At the Java DEMOgrounds - Oracle Java ME Embedded Enables the “Internet of Things”

    - by Janice J. Heiss
    I caught up with Oracle’s Robert Barnes, Senior Director, Java Product Management, who was demonstrating a new product from Oracle’s Java Platform, Micro Edition (Java ME) product portfolio, Oracle Java ME Embedded 3.2, a complete client Java runtime optimized for microcontrollers and other resource-constrained devices. Oracle’s Java ME Embedded 3.2 is a Java ME runtime based on CLDC 1.1 (JSR-139) and IMP-NG (JSR-228).“What we are showing here is the Java ME Embedded 3.2 that we announced last week,” explained Barnes. “It’s the start of the 'Internet of Things,’ in which you have very very small devices that are on the edge of the network where the sensors sit. You often have a middle area called a gateway or a concentrator which is fairly middle to higher performance. On the back end you have a very high performance server. What this is showing is Java spanning all the way from the server side right down towards the type of chip that you will get at the sensor side as the network.” Barnes explained that he had two different demos running.The first, called the Solar Panel System Demo, measures the brightness of the light.  “This,” said Barnes, “is a light source demo with a Cortex M3 controlling the motor, on the end of which is a sensor which is measuring the brightness of the lamp. This is recording the data of the brightness of the lamp and as we move the lamp out of the way, we should be able using the server to turn the sensor towards the lamp so the brightness reading will go higher. This sends the message back to the server and we can look at the web server sitting on the PC underneath the desk. We can actually see the data being passed back effectively through a back office type of function within a utility environment.” The second demo, the Smart Grid Response Demo, Barnes explained, “has the same board and processor and is still using Java ME embedded with a different app on top. This is a demand response demo. What we are seeing within the managing environment is that people want to track the pricing signals of the electricity. If it’s particularly expensive at any point in time, they may turn something off. This demo sets the price of the electricity as though this is coming from the back of the server sending pricing signals to my home.” The demo had a lamp and a fan and it was tracking the price of electricity. “If I set the price of the electricity to go over 5 cents, then the device will turn off,” explained Barnes. “I can go into my settings and, in this case, change the price to 50 cents and we can wait a minus and the lamp will go off. When I change the pricing signal so that it is lower, the lamp will come back on. The key point is that the Java software we have running is the same across all the different devices; it’s a way to build applications across multiple devices using the same software. This is important because it fixes peak loading on the network and can stops blackouts.” This demo brought me back to a prior decade when Sun Microsystems first promoted  Jini technology, a version of Java that would put everything on the network and give us the smart home. Your home would be automated to tell you when you were out of milk, when to change your light bulbs, etc. You would have access to the web and the network throughout your home.It’s interesting to see how technology moves over time – from the smart home to the Internet of Things.

  • Why won't Ubuntu copy large files to FAT32 flash Drives?

    - by yurividal
    Since I installed 11.10 I am unable to copy large files (say 1gb or more) to ANY usb drive that is formated as FAT. The file starts copying, but soon an error appears, saying "Unable to Copy" . "Error splicing file: Input/output error". I am able to do it via terminal, using the cp command. I use Gnome3, but the same error has happened in Unity as well. Apparently it works if I format the USB drive as NTFS or EXT3, EXT4. But, for many appliances, FAT is necessary. The problem is also not with the USB port, because it works under Windows. It did not happen before, when I had 10.04 installed.

  • How do I use a 4GB USB flash drive to install Ubuntu 12.10?

    - by Logan
    I've downloaded "ubuntu-12.10-desktop-amd64" and used Pen Drive Linux to get it onto my USB. I then restarted my computer (a Windows 7 Home Premium edition) and entered the boot menu to have it boot from the Sandisk USB (it called it Sandisk Cruzer Cruzer). Linux came up and asked if I wanted to try or install. I picked install, connected to my Wi-Fi, and installed it. After my laptop restarted, Windows booted immediately. I have tried several times and cannot get a choice between the two. P.S. I have used the Windows Installer, Wubi, but at the last second it gave me some kind of error.

  • Which Large File System Format to use for USB Flash drive compatible with Ubuntu/Mac/Windows?

    - by wajiw
    I've had this problem for a long time and can't find a solution. I switch between the 3 OSes all the time and use a 1TB USB Drive to do so. I can't seem to find a format that is compatible across all systems that handles large files (at least 8-9 GB). Does anyone have a solution for this? Recently I've tried exFat but that messes up the filesystem when trying to read on windows after adding files from Ubuntu (using the fuse driver). The OSes currently I'm using are Windows Vista/7, Mac OS X (10.6.5) and Ubuntu 10.10

  • Passing an ActionScript JPG Byte Array to Javscript (and eventually to PHP)

    - by Gus
    Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database. We don't have PHP to interact with Flash anymore, but we still need to allow users to take and save photos. We don't know how to save a JPG that Flash creates in a local database. Our hope was that we could save the byte array, a serialized string, or somehow actually persist the object itself, then pass it back to either PHP or Flash (and then PHP) to recreate the JPG. We have tried: - passing the byte array to Javascript instead of PHP, but javascript doesn't seem to be able to do anything with it (the object seems to be stripped of its methods) - stringifying the byte array in Flash, and then passing it to Javascript, but we always get the same string: ÿØÿà Now we are thinking of serializing the string in Flash, passing it to Javascript, then on the return route, passing that string back to Flash which will then pass it to PHP to be reconstructed as a JPG. (whew). Since no one on our team has extensive Flash background, we're a bit lost. Is serialization the way to go? Is there a more realistic way to do this? Does anyone have any experience with this sort of thing? Perhaps we can build a javascript class that is the same as the byte array class in AS?

  • Flex/Actionscript image display problem.

    - by IanH
    I'm trying to extend the Image class but hit a problem that I can't get past. I have a private image (img) that loads an image and a function that takes that image and copies it onto the parent. The debug function "copyit2" displays the image fine (so I know it's loaded OK). But the function "copyit" doesn't work - it just displays a white rectangle. I can't see how to make copyit work so that the original image is copied to the BitmapData and then subsequenty copied onto the parent? (The idea is to do some processing on the Bitmap data before it is displayed, although this isn't shown here to keep the example simple.) I suspect it is something to do with the security of loading images, but I'm loading it from the same server as the application is run from - so this shouldn't be a problem? Thanks for any help anyone can provide. Ian package zoomapackage { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.net.*; import mx.controls.Image; import mx.events.FlexEvent; public dynamic class Zooma extends Image { private var img:Image; public function copyit():void { var imgObj:BitmapData = new BitmapData(img.content.width, img.content.height, false); imgObj.draw(img); var matrix:Matrix = new Matrix(); this.graphics.beginBitmapFill(imgObj, matrix, false,true); this.graphics.drawRect(0, 0, this.width , this.height); this.graphics.endFill(); } public function copyit2():void { this.source = img.source; } public function Zooma() { super(); img = new Image(); img.load("http://localhost/Koala.jpg"); } } }

  • What lasts longer: Data stored on non-volatile flash RAM, optical media, or magnetic disk?

    - by Chris W. Rea
    What lasts longer: Data stored on non-volatile flash RAM (USB stick or SD cards?), optical media (CD, DVD, or Blu-Ray?), or magnetic disk (floppies, hard drives?) My gut tells me optical media, but I'm not sure. Furthermore, which of those digital media would be most suitable for long-term data storage where environmental issues are unknown, such as low/high temperature or humidity? For example, what digital media could be stored in a basement, attic, or time capsule, and be expected to survive a reasonably long time? e.g. a lifetime, and then some. Update: Looks like optical media and magnetic tape each have one vote below. Does anybody else have an opinion or know of a study comparing the two?

  • DD-WRT: What firmware and what webserver will fit on my 8MB of flash?

    - by Jeshii
    Attempting to make a portable WiFi webserver with php support on an old WRT54GS (v1.0) with DD-WRT. I have 8MB of flash on there. I know, it's a tall order. I tried the combination of dd-wrt.v24-13064_VINT_openvpn_jffs_small.bin, optware, and lighttpd. Didn't have enough space. Now I'm going to try dd-wrt.v24-13064_VINT_mini.bin, but I'm only saving 300KB, and I don't think that is going to make the difference. Any other small http servers with php support? Heck, I didn't even got to the point where I could add php! Maybe a way to calculate the size and dependencies of packages from optware BEFORE trying to install is more what I'm looking for. Any ideas?

  • Is it possible to live-boot VirtualBox from a USB flash drive?

    - by bw.
    To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

  • Does a dedicated video card improve HTML5 websites, Skype or Flash games performance?

    - by Kiewic
    I have read that having a dedicated video card (GPU) improves performance if you use your computer to play video games. I guess to make this happen, video games or apps must be using especial libraries designed to share the workload with the GPU, maybe Direct X or OpenGL, I don't know. Am I wrong? So, can HTML5 websites, Adobe Illustrator, Flash games (Zynga games), Skype or Netflix benefit from a dedicated video card? I usually do the previous activities simultaneously. Should I consider changing from an integrated video card to a dedicated card if I want to improve performance? Thanks.

  • How can I re-program/flash a backup of the bios?

    - by user285705
    I have some computers that have a particular bios setting that keeps everything running smoothly. The setting is not the default setting for the motherboard. So, when the CMOS battery dies, the setting is erased and causes the user problems. How can I backup the bios and settings I have now, and flash that file onto my entire stock of computers? I have attempted to use awdflash to backup my bios and then attempt to write that backup to the ROM chip, but I keep getting an error. It tells me that my file number doesn't match the system, or something like that. Basically, the file is incompatible with the chip. But I just backed it up from that chip. If anyone can shed some light on this for me it would be helpful.

  • Ubuntu USB flash boot drive gets spontaneous "Unhandled sense code" error and causes drive to switch to Write protected

  • How do I add "Press any key to boot from usb" when installing Windows from a flash drive? (Grub4dos question / how to remove a bootloader)

    - by Vincent
    Hi there! I've been struggling with this problem for a while now and finially decided to ask for help. Let me first explain what the main purpose of the app is: to provide the a very easy to use way of backing up files, after which I format the drive and start Windows 7 setup. I do this by booting WinPE, which runs a script to detect Windows installations and then opens a file browser. After the file browser is closed, the script continues and formats the drive that contains the Windows installation, and starts an unattended Windows 7 install. Now here is the problem: When you start Windows setup or WinPE from a dvd, you get a nice option to "Press any key to boot from DVD". This is to prevent the computer from booting the DVD when the first phase of the installation is complete and the computer reboots. However, when booting from a flash drive, Windows does not provide this option: it simply boots the flash drive every reboot. To replicate the "press any key" function, I installed Grub4Dos, which works great. It provides a small menu, the first standard item being "Continue installation", the second being "start installation". After quite a lot of tweaking, I got everything working: Start installation starts WinPE, which in turn starts the Windows installation. At first reboot, the Grub4Dos menu comes up, counts 5 seconds and boots the second stage of the installation. Here, I am greeted with the error: "Windows setup could not configure windows to run on this computer's hardware." When I boot into WinPE the normal way (put the bootmgr on the stick root) and change my bios to boot from the primary hdd after first reboot, I don't get this error. I've been looking around, and the only thing I could find was that the BIOS automatically names the boot device hd0, and that Windows can only be run / installed to hd 0. I'm not sure if this is the problem. I read about remapping to solve this problem, but to do that you have to know the phisical location of the hard drive and partition, like hd(0,1). I want this flash drive to work on any PC, regardless of where the OS is installed, so that's not really a possibility. A possible fix I thought of is removing the bootloader from the flash drive when I'm in WinPE. That way, when the pc reboots the BIOS will not see the flash drive as a boot drive and instead boot the primary hdd. I have yet to find a way to do this. Thank you for reading my question, and if you have any suggestion, please do.

  • How to fix notifyDataSetChanged/ListView problems in dynamic Adapter wrapper Android

    - by ipaterson
    Summary: Trying to dynamically add heading rows to a ListView via a custom adapter wrapper. ListView is having trouble keeping the scroll position in sync. Runnable demo project provided. I would like to dynamically add items to a list based on the values in a CursorAdapter, several positions ahead of what the user is currently viewing. To do this, I have an adapter that wraps the CursorAdapter and keeps the new content indexed in a SparseArray. The ListView needs to be updated when items are added to the custom adapter, but I have met a lot of pitfalls trying to get that to work and would love some advice. The demo project can be downloaded here: http://dl.dropbox.com/u/15334423/DynamicSectionedList.zip In the demo, the headings are added dynamically by looking ahead 10 places to find the correct position where the list items switch to the next letter. Each implementation of notifyDataSetChanged has problems as described: Demo 1 This demo shows the importance of notifyDataSetChanged(). On clicking anything, the app will crash. This is due to some sanity checking in ListView... mItemCount != adapter.getItemCount(). Moral is, we need to notify the list that data has changed. Demo 2 The natural next step is to notify the ListView of changes when changes occur. Unfortunately, doing so while the ListView is scrolling firmly breaks all touch interaction until the app switches out of touch mode. You will need to "fling scroll" far enough to generate new headings in order to notice this. Tapping the screen will not cause the scroll to stop, and once stopped none of the list items will be clickable. This is due to some if (!mDataChanged) { /* do very important stuff */ } code in AbsListView.onTouchEvent(). Demo 3 To fix this, Demo 3 introduces a pendingChanges flag and the custom Adapter gains a notifyDataSetChangedIfNeeded() which can be called by the ListView once it has entered a "safe" state for changes. The first point where changes must be notified is in ListView.layoutChildren(), so I overrode that method to first notify of changes if needed, then call through. Fling past at least one heading then click a list item. This doesn't quite work right, though I'm not totally sure why. Tapping or selecting an item with the keyboard/trackball causes the list to refresh without properly syncing the old position. It scrolls to the top of the list which is not acceptable. Demo 4 The scroll problem in Demo 3 can be conquered, at least in touch mode. By adding a call to notifyDataSetChangedIfNeeded() on touch down, the data change happens to take place at such a time that all touch interaction works as expected and the list position is properly synced. However, I can't find an analog for that when the device is not in touch mode, not to mention the fact that it definitely seems like a hack. The list almost always scrolls back to the top, I can't find out what causes it to occasionally maintain the correct position. Since Android is fighting me at each step of the way, I feel like there should be a better approach. Please try the demo, if any fixes can be applied to get it working that would be great! Many thanks to anyone who can look into this, hopefully if we can get the code working it will be useful for others trying to accomplish the same optimization for lists with headings.
