  • How do I mount a HFS+ dd image in OSX?

    - by Paul McMillan
    I had an HFS+ formatted drive that was going bad and wouldn't mount at all on OSX. I created an image using ddrescue on linux, and was able to save most of it. I can mount the drive and see the data just fine in linux using this: mount -o loop -t hfsplus dd_image /Volumes/mountpoint This doesn't work on my OSX system since hfsplus isn't a valid filesystem type. If I try: mount -t hfs image mountpoint It complains that it needs a block device. What's the fix here?

  • Prevent Outlook 2010 Insert Picture resizing image

    - by Rup
    When I "Insert Picture" a JPEG in Outlook 2010 it automatically resizes the image and, I think, recompresses it too. I realise this would be useful for photographs or for people who try to email 1MB BMPs but I would like to email around an image at the original pixel size without recompression. Is there a way to turn this off, or better still choose settings for each image insert? I found this page in the Office help. It's for Word, PowerPoint and Excel not Outlook but points you at File, Options, Advanced, Image Settings. There's no equivalent section in Outlook. I know Outlook uses Word as its editor so I've looked at Word's settings but there isn't an 'original size' here: there's only 'turn off image recompression' and pick target DPI from 96, 150, 220. I guess Office is finding a DPI value in the JPEG file and scaling it up or down to match this setting. I can't find an equivalent option in Outlook's options menu but there's so many settings and pop-up dialogs I may have missed something. Picture Format, Reset image size resets the image to the rescaled version, not the original. I can't see a way to edit a pixel value into size values in the image properties after insert. Thanks! I realise I can probably achieve this by editing the image metadata in PhotoShop elements or similar but there ought to be a way without editing the file? This is new behaviour in Outlook 2010; 2007 didn't do this.

  • How can I mount an image from an external HDD to a partition within the host system?

    - by HardwareMuch
    I'm currently using Acronis True Image Home 2010 and I have created an image of my Windows 7 OS. I copied it to my external HDD and I repartitioned my other PC's HDD. The primary partition houses the Windows Xp system which also has Acronis installed. The new partition is logical. Whenever I try to go through the steps on "Clone Disk" the program would not let me select a destination drive if I choose the external HDD as the source. I also did not know that it you can only select disks instead of partitions as a source or destination. Any suggestions would be greatly appreciated. Thanks.

  • How do I make an encrypted disk image on Debian?

    - by Blacklight Shining
    I'm basically looking for an equivalent to OS X's encrypted sparsebundles. The solution should have support for file ACLs and should not force me to specify a size in the beginning (the image should only take up as much space as it needs) or require root access to mount and unmount. Ideally, I should be able to set two different passwords (both for the same data), but that's not too important. (I do have root access to the machine and so can install packages and such, but I would rather not have to sudo just to mount an image.)

  • Linux RHEL : Making disk image efficiently

    - by TheProfoundGeek
    I have a linux box having RHEL. Its disk (hda1) is having free space of about 25GB. I have an another disk (hda2) which is of 250GB having another RHEL instance, it's partitioned for 200GB. Data on the disk occupies about 21GB of data. The image of hda2 needs to be taken and restored on other disk of same specs. What is the best way to make image file of the hda2? Ideally the images size should be around 25GBs as the actual data on the disk is just 21GB. I am aware about the following two methods. Method 1 : Raw Image dd if=/dev/hda2 of=/path/to/image dd if=/path/to/image of=/dev/hda3 Question 1 : Will the above method make a gigantic image of 250GBs? Is it efficient? Method 2 : Compressed Image. dd if=/dev/hda2 | gzip > /path/to/image.gz gzip -dc /path/to/image.gz | dd of=/dev/hda2 Question 2 : I tried the method 2, its taking too long. What are the pit falls of this methods? Which of the above method id efficient and why? Is there any other Linux utility which can do the job? Third party tools are no no.

  • Rip and Convert DVD’s to an ISO Image

    - by Mysticgeek
    If you own a lot of DVD’s, you might want to convert them to an ISO image for backup and easily playing them on your media center. Today we take a look at ripping your discs using DVDFab, then using ImgBurn to create an ISO image of the ripped DVD files. Rip DVD with DVDFab6 DVDFab will remove copy protection and rip the DVD files for free. Other components in the suite require you to purchase a license after the 30 day trial, but you’ll still be able to rip DVD’s after the trial. Install DVDFab by accepting the defaults (link below)…a system restart is required to complete the install process. The first time you run it, a welcome screen is displayed. If you don’t want to see it again check the box Do not show again, then Start DVDFab.  Pop the DVD in your drive and click Next. Now select your region and check Do not show again, then OK. It will then open the DVD and begin to scan it. Under DVD to DVD you can select either Full Disc or Main Movie depending on what you want to rip. If you want to burn the DVD to a disc after it’s created select the Full Disc option. Now click the Start button to begin the ripping process. After the ripping process has completed, you’ll get a message telling you it’s waiting for you to put in a blank DVD. Since we aren’t burning the disc, just cancel the message. Click Finish and close out of DVDFab or just minimize it if you’re going to keep using it to rip another DVD. By default the temporary directory is in My Documents \ DVDFab \ Temp…however you can change it in settings. If you go to the Temp directory you’ll see the DVD files listed there… Convert Files to ISO with ImgBurn Now that we have the files ripped from the DVD, we need to convert them to an ISO image using ImgBurn (link below). Open it up and from the main menu click on Create image file from files/folders. Click on the folder icon to browse to the location of the ripped DVD files. Browse to the DVDFab temp directory and the VIDEO_TS folder for the source and click Ok. Then choose a destination directory, give the ISO a name, and click Save. In this case we ripped the Unbreakable DVD, so named it that.   So now in ImgBurn you have the source being the ripped DVD files, and the destination for the ISO…then click the Build button. If you don’t create a volume label, ImgBurn is kind enough to create on for you. If everything looks correct, click Ok. Now wait while ImgBurn goes through the process of converting the ripped DVD files to an ISO image. The process has successfully completed. The ISO image of the DVD will be in the output directory you selected earlier. Now you can burn the ISO image to a blank DVD or store it on an external hard drive for safe keeping. When you’re done, you’ll probably want to go into the temp DVDFab folder and delete the VOB and other files in the Video_TS folder as they will take up a lot of space on your hard drive.   Conclusion Although this method requires two programs to make an ISO out of a DVD, it’s extremely quick. When burning DVD’s of various lengths, it took less than 30 minutes to get the final ISO.

  • How do I prevent my form from freezing when it is loading an image from the web at the click of a button?

    I want to display an image from the web to a panel in another Jframe at the click of a button but whenever I click the button first the image loads and during this time the current form potentially freezes and once the image has loaded the form is displayed with the image..

  • science.js’s loess() output is identical to input

    - by user3710111
    Rendered project available here. The line is supposed to be a trend line (as rendered with LOESS), but it merely follows each data point instead. I am no stats wonk, so maybe it makes sense that a LOESS function’s output would match the input as seen in the above example, but it strikes me as being wrong. Here is the relevant bit of code: var loess = science.stats.loess().bandwidth(.2); var xVal = data.map(function(d) { return d.date; }); var yVal = data.map(function(d) { return d.A; }); var loessData = loess([xVal], [yVal])[0]; console.log(yVal); console.log(loessData);

  • Laws of Computer Science and Programming

    - by Jonas
    We have Amdahl's law that basically states that if your program is 10% sequential you can get a maximum 10x performance boost by parallelizing your application. Another one is Wadler's law which states that In any language design, the total time spent discussing a feature in this list is proportional to two raised to the power of its position. 0. Semantics 1. Syntax 2. Lexical syntax 3. Lexical syntax of comments My question is this: What are the most important (or at least significant / funny but true / sad but true) laws of Computer Science and programming? I want named laws, and not random theorems, So an answer should look something like Surname's (law|theorem|conjecture|corollary...) Please state the law in your answer, and not only a link. Edit: The name of the law does not need to contain it's inventors surname. But I do want to know who stated (and perhaps proved) the law

  • Combine drivers from multiple Win7 installs to single image

    - by MikeyB
    I need to prepare a Windows 7 image with drivers for multiple systems (Lenovo laptops). I currently have an image prepared on one laptop type but need to grab the drivers appropriate for the other laptop types as well to ensure that it works on all systems. From what I can tell, the procedure will be: create a boot CD with imageX take a .wim image prepared on the first type of systems take .wim images from the other systems mount the other images in WAIK extract the drivers from the other images inject the drivers into the first .wim boot a system with the boot CD and redeploy the updated .wim image into the Windows partition take an image of the drive with usual imaging tools This all seems a little too convoluted, but I'm willing to do it to get the proper drivers into the image. This is (seemingly) necessarily complicated by having more than one OS on the disk image. Am I on the right track?

  • image appears larger than bounding rectangle?

    - by Kildareflare
    Hello I'm implementing a custom print preview control. One of the objects it needs to display is an image which can be several pages high and wide. I've successfully divided the image into pages and displayed them in the correct order. Each "page" is drawn within the marginbounds. (That is, each page is sized to be the same as the marginBounds.) The problem I have is that the image the page represents exceeds the bottom margin. However if I draw a rectangle with the same dimensions as the image, at the same position as the image, the rectangle matches the marginbounds. Thus when drawn to the page (in print preview and printed page) the image is larger than a rectangle drawn based on the image dimensions. I.e. The image is drawn at the same size as e.MarignBounds and is drawn at e.MarginBounds.Location yet exceeds the bottom margin. How is this? I've checked resoutions at each step of the process and they are all 96DPI. //... private List<Image> m_printImages = new List<Image>(); //... private void ImagePrintDocument_PrintPage(object sender, PrintPageEventArgs e) { PrepareImageForPrinting(e); e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(e.MarginBounds.X, e.MarginBounds.Y); e.Graphics.DrawRectangle(new Pen(Color.Blue, 1.0F), new Rectangle( new Point(e.MarginBounds.X, e.MarginBounds.Y), new Size(m_printImages[m_currentPage].Width, m_printImages[m_currentPage].Height))); //rest of handler } PS Not able to show an image as free image hosting blocked here.

  • PHP & MySQL Image deletion problem?

    - by IMAGE
    I have this script that deletes a users avatar image that is stored in a folder name thumbs and another named images and the image name is stored in a mysql database. But for some reason the script deletes all the users info for example if the users id is 3 all of the users info like first name last name age and so are deleted as well, basically everything is deleted including the user how do I fix this so only the images and image name is deleted? Here is the code. $user_id = '3'; if (isset($_POST['delete_image'])) { $a = "SELECT * FROM users WHERE avatar = '". $avatar ."' AND user_id = '". $user_id ."'"; $r = mysqli_query ($mysqli, $a) or trigger_error("Query: $a\n<br />MySQL Error: " . mysqli_error($mysqli)); if ($r == TRUE) { unlink("../members/" . $user_id .

  • DosBox Booting From HDD Image, FreeDOS Image created with qemu-img.

    - by TechZilla
    I'm having trouble booting a HDD image with DosBox. I've only gotten either read errors, or boot failures. The HDD image is a verified working FreeDOS installation, created with qemu-img. The image has been formatted FAT32, and it's working as expected with QEMU. The Image is only 1G in size, and is a flat raw image. I have been able to mount it with Linux, for ease of file transfer. I even was able to boot with DOSEMU, After I mounted the image under Linux. I would love to somehow just boot from the raw image file, but I would have no problem booting from a mount. I just can't get anything to happen, and I have read the Documents over. I have verified DosBox is working as expected, with its included DOSlike environment. I would appreciate any help, as I just don't have much of DosBox experience.

  • Getting started with object detection - Image segmentation algorithm

    - by Dev Kanchen
    Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time. I'm starting with trying to find a good image segmentation algorithm that provide a good jump-off point for the object detection phase. The target images would be "real-world" scenes. I found two techniques which mirrored my thoughts on how to go about this: Graph-based Image Segmentation: http://www.cs.cornell.edu/~dph/papers/seg-ijcv.pdf Contour and Texture Analysis for Image Segmentation: http://www.eng.utah.edu/~bresee/compvision/files/MalikBLS.pdf The first one was really intuitive to understand and seems simple enough to implement, while the second was closer to my initial thoughts on how to go about this (combine color/intensity and texture information to find regions). But it's an order of magnitude more complex (at least for me). My question is - are there any other algorithms I should be looking at that provide the kind of results that these two, specific papers have arrived at. Are there updated versions of these techniques already floating around. Like I mentioned earlier, the goal is relative accuracy of image segmentation (with an eventual aim to achieve a degree of accuracy of object detection) over runtime, with the algorithm being able to segment an image into "naturally" or perceptually important components, as these two algorithms do (each to varying extents). Thanks! P.S.1: I found these two papers after a couple of days of refining my search terms and learning new ones relevant to the exact kind of techniques I was looking for. :) I have just about reached the end of my personal Google creativity, which is why I am finally here! Thanks for the help. P.S.2: I couldn't find good tags for this question. If some relevant ones exist, @mods please add them. P.S.3: I do not know if this is a better fit for cstheory.stackexchange (or even cs.stackexchange). I looked but cstheory seems more appropriate for intricate algorithmic discussions than a broad question like this. Also, I couldn't find any relevant tags there either! But please do move if appropriate.

  • Ich bin jetzt Oracle Certified Associate!

    - by britta.wolf
    Jan Peuker, Absolvent der Hochschule Augsburg und University of Melbourne, hat vor kurzem das Zertifikat Oracle Database 10g Administrator Certified Associate erworben. Er hat uns netterweise mit diesem kleinen Text versorgt: "Die Oracle Zertifizierung beginnt üblicherweise mit dem Oracle Certified Associate. Für diese Zertifizierung ist noch keine tiefgehende Praxiserfahrung notwendig. Um den Titel des Oracle Database 11g Administrator Certified Associate zu erlangen, muss man eine Prüfung zu SQL (z.B. 1Z0-051) sowie eine Prüfung zur Administration (1Z0-045) ablegen. Beide Prüfungen dauern 2 Stunden und haben ca. 80 Fragen von denen etwa drei Viertel richtig beantwortet werden müssen, um zu bestehen. Eine Note gibt es nicht. Die Prüfungen finden immer elektronisch statt, die Software erlaubt das Überspringen und Markieren von Fragen. Während meiner Arbeitszeit nach meinem ersten Studium hatte ich häufig mit dem Oracle Datenbanksystem zu tun. Als ich mein Aufbaustudium an der University of Melbourne absolvierte, wurde mir von der Studienberaterin vorgeschlagen, den Kurs „Advanced Database Administration" zu belegen. Dieser beruht vollständig auf den offiziellen Oracle Trainings-Unterlagen zur Prüfung in Oracle Administration und erlaubt daher die Teilnahme an der offiziellen Zertifizierung. Im Gegensatz zur SQL Prüfung, deren Inhalt man sich gut selbst aneignen kann, hilft bei der Administrator-Zertifizierung ein echter Kurs mit Seminar ungemein. Viele Konzepte lassen sich schwer aus einem Buch lernen. Die Bestandteile der SGA oder das Anlegen von Benutzern mögen leicht zugänglich sein, Redo- und Undo-Management sowie Backup und Recovery kann man nur verstehen, wenn man Beispiele hat und diese an einem Testsystem (keine "kleine" XE-Datenbank, sondern eine "richtige" Datenbank mit Enterprise Manager) ausprobieren kann. Übermäßig viel Zeit habe ich keinesfalls investiert, weil das Grundsystem sehr logisch ist. Für die weniger nachvollziehbaren Bereiche, besonders die neuen Features, habe ich mir Fachbegriffe auf Lernkarten geschrieben und die Trainingsunterlagen am System durchgespielt. Die Prüfung war für mich überraschend schwer, weil das einfache "Tagesgeschäft" deutlich unterrepräsentiert ist. In den Multiple-Choice-Fragen werden viele Besonderheiten und Use-Cases abgefragt (online findet man viele Beispielfragen). Da beide Tests in Englisch sind, sollte man nicht nur in der Terminologie des Oracle Datenbanksystems sondern auch in Fachbegriffen der Datenbankwelt allgemein bewandert sein. Oft machen einzelne Wörter (z.B. redundant oder synchronized, redo log oder redo log buffer) die richtige Antwort aus, ein signifikanter Anteil der Fragen beruht auf Zeichnungen oder Diagrammen, die beschrieben werden müssen. So muss man z.B. anhand eines Log-Auszugs beurteilen, warum die Datenbank nicht sauber geschlossen wurde. Allgemeines Wissen über Datenbanksysteme hilft leider nicht viel, da überproportional viele Fragen zu Oracle-spezifischen Themen gestellt werden, wie z.B. Optimierungs-Dienste (ADDM), Flashback, SQL Loader und ein wenig PL/SQL. Die SQL Prüfung ist dagegen sehr geradlinig - was aber nicht einfacher heißt. Hier kommt es mehr auf Auswendiglernen von Syntax an, was mir persönlich nicht liegt. Vor allem als Anwendungsprogrammierer kennt man oft proprietäre SQL-Funktionen nicht, es fällt schwer, sich einzelne Datumsberechnungsfunktionen, Typkonvertierungen, Namespaces oder krude Join-Methoden zu merken. Auf all dies wird in der Prüfung aber sehr viel Wert gelegt. Auch hier wird man wieder mit zweideutigen Multiple-Choice Fragen konfrontiert, bei denen sich z.B. nur die Reihenfolge der Parameter unterscheidet. Zudem sind die Parameter auch nicht ausgeschrieben, sondern in einem Entity-Relationship-Diagramm gegeben, wobei man auf die richtigen Datentypen achten muss. Mir persönlich war die Zeit fast zu knapp bemessen, weil man bei vielen Fragen erst ein Diagramm, einen Datenauszug oder einen längeren Text lesen muss, um dann die richtigen Statements zu finden. Hier helfen Lernkarten also nur bedingt - stattdessen üben, üben, üben. Durch den relativ niedrigen Pass-Score von 70% kann man es sich leisten, unsichere Fragen zuerst zu überspringen und erst nachdem alle sicheren beantwortet sind, zu überdenken. Die Prüfung ist auf jeden Fall fair. Ich habe durch das Oracle-Zertifizierungsprogramm viel gelernt. Die Datenbanken unter meiner Aufsicht laufen deutlich performanter und liefern höhere Verfügbarkeit, weil ich Probleme eliminieren konnte, die mir vorher nicht klar waren. Eine klassische Misskonfiguration, volle Archive Logs, weil diese mit zu lange gehaltenem Flashback-Speicher kollidieren, konnte ich bereits in einer der ersten Stunden meines Kurses an der Uni Melbourne mit Hilfe meines Professors klären. Beide Prüfungen waren problemlos parallel zu anderen Prüfungen zu absolvieren. Empfehlen kann ich eine gründliche Online-Recherche aber auch die Oracle Press-Bücher, welche mit Prüfungsfragen am Ende jedes Kapitels aufwarten. So spart man sich Zeit und ist trotzdem gut vorbereitet. Auch wenn ich keine Laufbahn als Administrator einschlagen werde, bin ich froh die zugrundeliegende Technologie vieler Anwendungen besser zu verstehen. Für meine tägliche Arbeit als Anwendungsentwickler hat es mir vor allem geholfen, Oracle-Konzepte z.B. im Bereich der Transaktionssteuerung und Wiederherstellung zu verstehen und damit viele Open Source Produkte jetzt sinnvoller bewerten und empfehlen zu können." Eine Übersicht der Zertifizierungspfade finden Sie auf der Oracle University Webseite (dann einfach "Deutschland""auswählen und anschließend auf den Punkt "Zertifizierungen" klicken).

  • Etch a Circuit Board using a Simple Homemade Mixture

    - by ETC
    If you’ve been dabbling in DIY electronics projects but you’re not so excited about keeping strong acids around to etch your circuit boards, this simple DIY recipe uses common household chemicals in lieu of strong acid. Electronics hobbyist Stephen Hobley wanted to see if he could create an etching solution that wasn’t as dangerous and noxious smelling at traditional muriatic acid solutions. By combining regular white vinegar, hydrogen peroxide, and table salt, he created a homemade etching solution from ingredients safe enough to store in your pantry. The only downside to his recipe is that, compared to traditional etching solutions, the process takes a little bit longer so you’ll have to leave your board in the solution longer. Not a bad trade off for the ability to skip using any oops-I-burned-my-skin-off acids. Check out the process in the video below: Hit up the link below for more information and and interesting explanation of the chemical process (he talks about not quite understanding it in the video but two chemists write in and give him the full run down).
