  • ubuntu fails to start

    - by miccaman
    I have a laptop with ubuntu 9.10 which fails to start, and I want to copy the data from it to an external hard disk. I can login in recovery mode command line, but then I cannot mount the external hard drive. (in recovery mode I cannot write to the laptops hard drive) If I boot from an portable USB with mintlinux, I can mount the external harddrive, and copy most of the data from the laptop, however there is a dir which I have no rights to access under /home/user/Documents then I get a permission denied error. Are there any other options?

  • Error mounting samba share, cannot mount block device xxxx read-only

    - by Jeff Ward
    After installing Ubuntu 12.04, I'm trying to mount a samba share from Windows under Linux, using a scripted command that's always worked, and the server hasn't changed. The error is as follows: $ mount -t cifs //<host>/<share> /media/<share> -o username=<user>,password=<pass> mount: block device //<host>/<share> is write-protected, mounting read-only mount: cannot mount block device //<host>/<share> read-only $ I've read a lot of discussions about permissions, but unfortunately, that wasn't the issue. I'm submitting my own answer below for reference, hope this helps someone else.

  • Should we encourage coding styles in favor of developer's autonomy, or discourage it in favor of consistency?

    - by Saeed Neamati
    A developer writes if/else blocks with one-line code statements like: if (condition) // Do this one-line code else // Do this one-line code Another uses curly braces for all of them: if (condition) { // Do this one-line code } else { // Do this one-line code } A developer first instantiates an object, then uses it: HelperClass helper = new HelperClass(); helper.DoSomething(); Another developer instantiates and uses the object in one line: new HelperClass().DoSomething(); A developer is more easy with arrays, and for loops: string[] ordinals = new string[] {'First', 'Second', 'Third'}; for (i = 0; i < ordinals.Length; i++) { // Do something } Another writes: List<string> ordinals = new List<string>() {'First', 'Second', 'Third'}; foreach (string ordinal in ordinals) { // Do something } I'm sure that you know what I'm talking about. I call it coding style (cause I don't know what it's called). But whatever we call it, is it good or bad? Does encouraging it have an effect of higher productivity of developers? Should we ask developers to try to write code the way we tell them, so to make the whole system become style-consistent?

  • Authentication issues setting up iRedMail on Debian

    - by Sergio Rinaudo
    I'm setting up an exchange server using iRedMail. Following the official iRedMail installation guide (http://www.iredmail.org/install_iredmail_on_debian.html) and the Digital Ocean guide (https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-04-x64) I was able to install iRedMail without any problems, so I have all the services up and running. I can configure domains and emails using iRedAdmin BUT I have problem both sending and receiving email, what I get from Roundcube is 'Authentication error' when trying to send an email. Also I can't receive anything. I also tried to connect to the mx server using telnet, it connects, but after the STARTTLS command, when I start to write "MAIL FROM:" the connection is lost. Something in the configuration is not working (at the moment I have the configuration written by the iRedMail installation) but I do not know where, I hope someone can enlight me! Thank you

  • MySQL Locking Up

    - by Ian
    I've got a innodb table that gets a lot of reads and almost no writes (like, 1 write for every 400,000 reads approx). I'm running into a pretty big problem though when I do INSERT into the table. MySQL completely locks up. It uses 100% cpu, and every single other table (in other databases even) have their statuses set to "Locked" until the INSERT is done. This is a big problem because MySQL stays locked up for up to 4 minutes. I'm using version 5.1.47 (rpm from mysql.com). Any ideas?

  • How do I easily elevate when running a .jar file?

    - by Merlyn Morgan-Graham
    When trying to run an installer Jar file, I am getting an error saying that write access is denied to create a directory under the Program Files folder. Right click - Run as Administrator is not available on Jar files (I assume because it is Java.exe that consumes them - they are not themselves treated as directly executable by the shell). What is the quickest and simplest way to run a .Jar file with elevation? I am evaluating this tool to recommend for our dev team, and they will manually install it on their boxes. I'd prefer an option that doesn't require them to type anything.

  • How to get started in the development industry? [closed]

    - by Peter Fren
    My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

  • Open NetApp CIFS Share

    - by kingfish
    I have a CIFS share on a NetApp device. I want this share to be completely open to any user/computer on the same network. I don't want any authentication (domain, workgroup, etc) required; no login/password should need to be provided. Currently I have CIFS configured to use "Domain - Windows 2000" authentication and have the permissions on the share set to "Everyone - Full Read/Write" but if you try to connect to it from a machine that isn't bound to the domain it is asking for login info.

  • Requiring mulitple group membership in order to access folder

    - by David
    How would I go about creating a file or folder that requires a user to be a member of two or more different groups in order to read/write to the folder? For example, say I run an auto repair shop, and I have a folder called "Repair History" and I only want people to access it if they are members of BOTH the "Mechanics" and "Cashiers" group? This would be an AND requirment instead of an OR requirement which seems to be the norm. I know we can create a separate group that is needed to access the folder, but this is more of an academic question, since it pertains to a different security structure that we are creating. I'm not sure if MS security handles it, but I'm wondering how it would be done either way.

  • linux/shell: change a file's modify timestamp relatively?

    - by index
    My Canon camera produces files like IMG_1234.JPG and MVI_1234.AVI. It also timestamps those files. Unfortunately during a trip to another timezone several cameras were used, one of which did not have the correct time zone set - meta data mess.. Now I would like to correct this (not EXIF, the file's "modify" timestamp on disk). Proposed algorithm: 1 read file's modify date 2 add delta, i.e. hhmmss (preferred: change timezone) 3 write new timestamp Unless someone knows a tool or a combination of tools that do the trick directly, maybe one could simplify the calculation using epoch time (seconds since ..) and whip up a shell script. Any help appreciated!

  • How do I tell if my Windows server is swapping?

    - by churnd
    I'm using Process Explorer to monitor my windows server while it reconstructs some data. It's primarily a CPU intensive process, but I want to make sure it's not swapping. How can I tell if it is using Process Explorer? My initial guess is in the System Information window, it's Paging File Write Delta. Yes? No? I'm an idiot? *Screenshot is not of the server... just an example.

  • Unable to debug an encodded javascript?

    - by miles away
    I’m having some problems debugging an encoded javacscript. This script I’m referring to given in this link over here. The encoding here is simple and it works by shifting the unicodes values to whatever Codekey was use during encoding. The code that does the decoding is given here in plain English below:- <script language="javascript"> function dF(s){ var s1=unescape(s.substr(0,s.length-1)); var t=''; for(i=0;i<s1.length;i++)t+=String.fromCharCode(s1.charCodeAt(i)-s.substr(s.length-1,1)); document.write(unescape(t)); } </script> I’m interested in knowing or understanding the values (e.g s1,t). Like for example when the value of i=0 what values would the following attributes / method would hold s1.charCodeAt(i) and s.substr(s.length-1,1) The reason I’m doing this is to understand as to how a CodeKey function really works. I don’t see anything in the code above which tells it to decode on the basis of codekey value. The only thing I can point in the encoding text is the last character which is set to 1 , 2 ,3 or 4 depending upon the codekey selected during encoding process. One can verify using the link I have given above. However, to debug, I’m using firebug addon with the script running as localhost on my wamp server. I’m able to put a breakpoint on the js using firebug but I’m unable to retrieve any of the user defined parameters or functions I mentioned above. I want to know under this context what would be best way to debug this encoded js.

  • Mini-jack problem with Sony Vaio (running XP)

    - by qftme
    I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

  • How can I perform a ping every X minuts and check the response time?

    - by Profete162
    I am currently working in a big company and we have serious latency issues. This is happening in a process control system, and is unacceptable (Open a valve sometimes take 2 minuts before command start) The Network team seems very lazy and I want to check when they say "everything alright on the network". So, I want to create a loop that ping the server and write the result in a text file. I am not a batch expert, but do you think this code is correct to use? @ECHO OFF :LOOPSTART time /T ping xxx.xx.x.x -t >> filename.txt sleep -m 3000 GOTO LOOPSTART

  • Worthless Anti-Spam (What can we learn)

    - by smehaffie
    I recently can across a site that had a “anti-spam” field at the bottom of the entry from.  The first issue I had with it was that at 1280X800 you could not read the value you were suppose to enter (see below).  You tell me, should you enter div, dlv, piv, or plv. But even worse than not being readable at high resolutions is the fact that the programmer who coded it really did not understand what this was used for.  An anti-spam (aka: catpcha) entry field should not be able to be read by looking at the HTML DOM object (so entry of value cannot be scripted).  In this case the value is simply a disabled text input filed that has the value you need to type.  So a hacker would simply need to search for text input field named “spam2” and then they could flood the site with spam. 1: <td> 2: <label> 3: <input name="spam1" type="text" class="small" id="spam1" size="6" maxlength="3" /> 4: <input name="spam2" type="text" class="small" id="spam2" value="plv" 5: disabled="disabled" size="6" maxlength="3" /> 6: * <span class="small">- Anti-SPAM key - please enter matching value</span> 7: </label> 8: </td>   There are some things to learn from this example: 1) Always make sure you understand why you are coding a feature/function for any program you write.  Just following the requirements without realizing the “why” will sooner or later come back to bite you.  I think the above example appears to be an example of this. 2) Always check how the screen appears in different resolutions.  In this case it was pretty much unreadable in 1280x800, but you could read it in 800X600 (but most people I know do not have their resolution set that low).  Lucky for me I could “View Source” and get the value I needed to enter.

  • preseeded installation keeps asking for confirmation while creating RAID-Partitions on certain hardware-platform

    - by Marc Shennon
    I am aware of the partman-md/confirm_nooverwrite thing, that was the solution to most of this problems in the past. The thing is, that the preseed-file works for almost all hardware-platforms I tested, but only for one (Primergy MX130) it keeps asking for confirmation, before writing the partition-layout to the disks. All machines I tested are running with two SATA Disks, nothing special. I'm not really sure, what information could be needed in order to investigate the cause of this behaviour, but I would of course be willing to provide more information, if someone has an idea. Relevant part of the preseed file is the following: d-i partman-auto/disk string /dev/sda /dev/sdb d-i partman-auto/method string raid d-i partman-md/confirm boolean true d-i partman-partitioning/confirm_write_new_label boolean true d-i partman-md/device_remove_md boolean true d-i partman/choose_partition select finish d-i partman-md/confirm_nooverwrite boolean true # Write the changes to disks? d-i partman/confirm boolean true d-i mdadm/boot_degraded boolean true # RECIPE # Next you need to specify the physical partitions that will be used. d-i partman-auto/expert_recipe string \ multiraid :: \ 500 10000 1000000000 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 512 1000 786 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 8192 10240 10240 raid $lvmignore{ }\ method{ raid } \ . # Parameters are: # <raidtype> <devcount> <sparecount> <fstype> <mountpoint> <devices> <sparedevices> d-i partman-auto-raid/recipe string \ 1 2 0 ext4 / /dev/sda1#/dev/sdb1 . \ 1 2 0 ext2 /boot /dev/sda2#/dev/sdb2 . \ 1 2 0 swap - /dev/sda5#/dev/sdb5 .

  • Web Crawler for Learnign Topics on Wikipedia

    - by Chris Okyen
    When I want to learn a vast topic on wikipedia, I don't know where to start. For instance say I want to learn about Binary Stars, I then have to know other things linked on that pages and linked pages on all the linked pages and so on for the specified number of levels. I want to write a web crawler like HTTracker or something similiar, that will display a heiarchy of the links on a certain page and the links on those linked pages.I wish to use as much prewritten code as possible. Here is an example: Pretending we are bending the rules by grabing links from only the first sentence of each pages The example archives and "processes" two levels deep The page is Ternary operation The First Level In mathematics a ternary operation is an N-ary operation The Second Level Under Mathmatics: Mathematics (from Greek µ???µa máthema, “knowledge, study, learning”) is the abstract study of topics encompassing quantity, structure, space, change and others; it has no generally accepted definition. Under N-ary In logic,mathematics, and computer science, the arity i/'ær?ti/ of a function or operation is the number of arguments or operands that the function takes Under Operation In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values ------------------------------------------------------------------------- I need some way to determine what oder to approach all these wiki pages to learn the concept ( in this case ternary operations )... Following along with this exmpakle, one way to show the path to read would a printout flowout like so: This shows that the first sentence of the Mathematics page doesn't link to the first sentence of pages linked on ternary page two levels deep. (Please tell me how I should explain this ) --- In otherwords, the child node of the top pages first sentence, ternary_operation, does not have any child nodes that reference the children of the top pages other children nodes- N-ary and operation. Thus it is safe to read this first. Since N-ary has a link to operations we shoudl read the operation page second and finally read the N-ary page last. Again, I wish to use as much prewritten code as possible, and was wondering what language to use and what would be the simpliest way to go about doing this if there isn't already somethign out there? Thank You!

  • Costs/profit of/when starting an indie company

    - by Jack
    In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

  • Apache Tomcat 6.0.29 startup causing Win XP SP3 reboot

    - by Liam
    Some of our Windows XP Developer machines die (black screen - no ping) when starting up Tomcat from a console. This only happens if the Tomcat debug console window is displayed (not minimised). When minimised, the startup / run is successful. I've checked for Tomcat logs and the crash sessions produce empty (zero bytes) tomcat log files. No system logs exist and no crash dump is created even though this is enabled in the Windows settings. The machine is dual screen and another machine with the same image has the same issue. The only clue is just before the crash, one of the monitors the system reports "Cannot display video mode 1280x1024" (approximate error, didn't write it down). Is there a way I can get Windows to produce log files of this crash session? Beyond running Tomcat as a service / minimised window, how can I fix (or even investigate)?

  • MVC: How to Implement Linked Views?

    - by cw'
    I'm developing a java application to visualize time series. I need (at least) three linked views, meaning that interaction with one of them updates the others. The views are: A list represents the available and currently selected time series. The selected time series are used as input for subsequent computations. Changing the selection should update the other views. A line chart displays the available and selected time series. Time series should be selectable from here by clicking on them. A bar chart shows aggregated data on time series. When zooming in to a period of time, the line chart should zoom in to the same period (and vice versa). How to implement this nicely, from a software engineering point of view? I.e. I'd like to write reusable and clear, maintainable code. So I thought of the MVC pattern. At first I liked the idea of having the three view components observing my model class and to refresh views upon being notified. But then, it didn't feel right to store view related data in the model. Storing e.g. the time series selection or plot zoom level in the model makes implications about the view which I wouldn't want in a reusable model. On the other hand, having the controllers observe each other results in a lot of dependencies. When adding another view, I'd have to register all other views as observer of the new view and vice versa, passing around many references and introducing dependencies. Maybe another "model" storing only view-related data would be the solution?

  • Limited access to Amazon S3 buckets

    - by Tomas Markauskas
    Is it possible to somehow limit the access to an Amazon S3 account. I don't really like the idea of distributing my secret access key to all of my applications, that want to access just a single bucket on my account. If someone gains access to one of the applications, I could loose all my data stored on S3. One way I was thinking to do it would be creating a second S3 account and give it access to just one bucket of the main account, but it's not really a great solution. Another nice thing for me would be to give the secondary account only write (but not modify/delete) and read access. That way I could upload backups or other files and be sure, that they won't get lost.

  • Hardware RAID 0 without OS re-installation

    - by sterz
    I have Ubuntu & Windows 7 installed on my hdd. Can I mirror the image of the hdd to the second identical drive? Is this not recommended (i.e have to re-install every OS)? If it is okay to mirror, is there anything else to do to make hw RAID 0 work? Does RAID 0 have the same risk as a single drive? What sector size would you recommend for read/write/extract video files (mostly each around 2 GB)?
