  • external USB HD doesn't show up on 'sudo fdisk -l' on one Ubuntu, shows up on another (both 'precise')

    - by Menelaos
    I have a 1.5TB WD external USB HDD and two Ubuntu systems, both 'precise'. When I plug the disk on system A it doesn't show up on the output of sudo fdisk -l nor is it automatically mounted (note that that wasn't always the case - it used to appear in the past). When I plug it on system B (again Ubuntu precise) it shows up when I do a sudo fdisk -l (output appended at the end) and mounts automatically just fine. What does this discrepancy point to and what kind of diagnostics should I run / tools I should use to troubleshoot the problem? I followed the suggestion I received to do a sudo tail -f /var/log/syslog and the output is the following when I plug, unplug and replug the USB cable on System A: Sep 14 23:27:09 thorin mtp-probe: checking bus 2, device 3: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:27:09 thorin mtp-probe: bus: 2, device: 3 was not an MTP device Sep 14 23:28:01 thorin kernel: [ 338.994295] usb 2-2: USB disconnect, device number 3 Sep 14 23:28:04 thorin kernel: [ 341.808139] usb 2-2: new high-speed USB device number 4 using ehci_hcd Sep 14 23:28:04 thorin mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:28:04 thorin mtp-probe: bus: 2, device: 4 was not an MTP device Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting due to inactivity Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting was requested (I guess the last two message are irrelevant).

  • Open source login solution

    - by David
    Authentication is such a general problem, which most websites have to implement. There are a few commercial solutions, but all lack sufficient functionality to customize the registration process. Therefore, I am looking for an open-source alternative. I am using PHP and with PostgreSQL as database, but as far as I understand one could utilize authentication solutions using other technologies and integrate them into our site in various ways. Therefore, I am looking for such solutions in any technology apart from those requiring Microsoft infrastructure... I would prefer Open Source solution, which have already implemented the following features: Has password recovery procedure Username is the email address of the user Has "Remember me" functionailty (meaning that the user is logged in automatically without seeing the login page) email address verification Google has gotten me nowhere on this and neither a search on this site...

  • Where can I find SPF record information for Network Solution hosted email?

    - by Steve Brown
    I have a client who has their e-mail hosted with Network Solutions and some of the e-mails they are sending are going to spam. I've searched Google for information on network solutions and SPF records but all the results have to do with "how to set up an SPF record" - which I understand how to do. The problem is that I can't find any information about what SPF records to use for network solutions hosted e-mail. I even tried lookup up spf records on networksolutions.com but it appears there are none. Where can I find SPF record information for Network Solution hosted email?

  • Is an extra collision-mesh for level-data worth the hassle?

    - by Serthy
    What is the optimal approach for collision-detection with the environment in an 3D engine (with triangle mesh based geometry, no bsp)? A) Use the render mesh [+] no need for additional work for artists to fiddle with collision detection [-] high detail is harder for physics calculation [+/-] maybe use collidable flags for materials [+/-] compute the collision-mesh from the render-mesh B) Use an additional collision mesh [+] faster/more optimal collision-detection [-] additional work (either by the artist or by the programmer who has to develop an algorithm to compute it from the render-mesh) [-] more memory useage How do AAA title handle this? And what are the indie dev's approaches?

  • How do I copy files between harddrives on Ubuntu CLI?

    - by ed209
    I have a dedicated server with a 120gb main ssd. The server happens to come with a couple of 3000GB hard drives. I'd like to use them to back up my main drive. Preferably, I'd like one as an exact copy of the main SSD and the other with incremental backups of the mysql database and a user uploads file. These are the drives I have Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f2e18 Device Boot Start End Blocks Id System /dev/sda1 2048 4196352 2097152+ 83 Linux /dev/sda2 4198400 5246976 524288+ 83 Linux /dev/sda3 5249024 234441647 114596312 83 Linux Disk /dev/sdb: 3000.6 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 3000.6 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdc doesn't contain a valid partition table The first problem I have, is that I have no idea how to copy from one drive to another.

(there is nothing under /mnt or /media)

  • My search what the Cloud will mean for my Work, part 2

    - by Kay Sellenrode
    My experience with the cloud and why work will change and not disappear. Until now I have multiple experiences with the cloud, for the most good. i have worked on multiple cloud solutions in the past but let me describe them as 0.x versions. For me the 1st real serious cloud experience was a bit more than 1 year ago, when our company switched from an in house server to Microsoft BPOS as a complete replacement. Since we are a small consultancy firm and don’t have that much else to do than consulting, our IT requirements are quite simple. We need Mail and Storage space for our documents. With the in house server we had multiple outages during a year, mostly by lack of administering. Being consultants in the field and hardly having time to maintain a server, BPOS was and still is for us the right solution. Since the migration we have less outages and a much more robust solution. Have we run into issues with BPOS for our own environment? No not that I’m aware of. Based on this experience I made a stance about deploy ability of BPOS and cloud solutions, they are suitable for MKB (Dutch for Medium and Small Businesses). Most Small businesses don’t have the amount of work to hire a full time it admin. Hiring a service provider to maintain their own server might be even more costly than hiring an admin. So seeing the capabilities of BPOS and the needs of most businesses I see it as a great solution that gives the business a complete Server replacement solution for a fixed price per user. resulting in a clear budget for IT spending, something most small businesses were looking for, for a long time. So right now I’m deploying BPOS with a customer, and I run into some of the Cloud 1.0 issues. In my opinion BPOS is a good working Cloud version 1.0 solution. What do I mean with 1.0? Well 1.0 is mostly a tested solution (unlike 0.x versions) but still have quite some limitations caused by too few market experience. in my opnion this is also the reason why we don’t see that much BPOS customers yet and why I think Office 365 will make a huge difference. What I have seen of 365 shows me it is a Cloud 2.0 version, meaning it has all needed features and is much more flexible to the customer. This is also why I see changes happen in my work field, changes and not unemployment due to Cloud solutions. Cloud 1.0 solutions gave me the idea that if every customer would adopt them I would be out of work. But in reality Cloud 1.0 solutions are here just to set the market needs. The Cloud 2.0 and higher versions will give the customer much more flexibility, but also require the need for a consultant. Where the 1.0 versions are simple to setup and maintain, the 2.0 solution needs more thought upfront and afterwards. ie. BPOS in its 1.0 version brings you a very simplified Exchange 2007 solution, Suitable for some customers. Looking at Office 365 you receive almost a full blown Exchange 2010 solution. I expect this to be even more customizable in the next version. In my search for the changes to my work I try to regulary write a post with my thought around the Cloud and the impact on my work as a consultant. I'm also planning to present around this topic, so if anyone is interested to see me present around this topic, you're more than welcome to contact me.

  • Comparing Isis, Google, and Paypal

    - by David Dorf
    Back in 2010 I was sure NFC would make great strides, but here we are two years later and NFC doesn't seem to be sticking. The obvious reason being the chicken-and-egg problem.  Retailers don't want to install the terminals until the phones support NFC, and vice-versa. So consumers continue to sit on the sidelines waiting for either side to blink and make the necessary investment.  In the meantime, EMV is looking for a way to sneak into the US with the help of the card brands. There are currently three major solutions that are battling in the marketplace.  All three know that replacing mag-stripe alone is not sufficient to move consumers.  Long-term it's the offers and loyalty programs combined with tendering that make NFC attractive. NFC solutions cross lots of barriers, so a strong partner system is required.  The solutions need to include the carriers, card brands, banks, handset manufacturers, POS terminals, and most of all lots of merchants.  Lots of coordination is necessary to make the solution seamless to the consumer. Google Wallet Google's problem has always been that only the Nexus phone has an NFC chip that supports their wallet.  There are a couple of additional phones out there now, but adoption is still slow.  They acquired Zavers a while back to incorporate digital coupons, but the the bulk of their users continue to be non-NFC.  They have taken an open approach by not specifying particular payment brands.  Google is piloting in San Francisco and New York, supporting both MasterCard PayPass and stored value. I suppose the other card brands may eventually follow.  There's no cost for consumers or merchants -- Google will make money via targeted ads. Isis Not long after Google announced its wallet, AT&T, Verizon, and T-Mobile announced a joint venture called Isis.  They are in the unique position of owning the SIM in the phones they issue.  At first it seemed Isis was a vehicle for the carriers to compete with the existing card brands, but Isis later switched to a generic wallet that supports the major card brands.  Isis reportedly charges issuers a $5 fee per customer per year.  Isis will pilot this summer in Salt Lake City and Austin. PayPal PayPal, the clear winner in the online payment space beyond traditional credit cards, is trying to move into physical stores.  After negotiations with Google to provide a wallet broke off, PayPal decided to avoid NFC altogether, at least for now, and focus on payments without any physical card or phone.  By avoiding NFC, consumers don't need an NFC-enabled phone and merchants don't need a new reader.  Consumers must enter their phone number and PIN in the merchant's existing device, or they can enter their PIN in the PayPal inStore app running on their phone, then show the merchant a unique barcode which authorizes payment. Paypal is free for consumers and charges a fee for merchants.  Its not clear, at least to me, how PayPal handles fraudulent transactions and whether the consumer is protected. The wildcard is, of course, Apple.  Their mobile technologies set the standard, so incorporating NFC chips would certainly accelerate adoption of many payment solutions.  Their announcement today of the iOS Passbook is a step in the right direction, but stops short of handling payments. For those retailers that have invested in modern terminals, it seems the best strategy is to support all the emerging solutions and let the consumers choose the winner.

  • How to find connected hosts at network (vpn or lan)

    - by Javier Novoa C.
    Hello, I'm looking for possible solutions to the following need: I have a VPN configured (using openVPN over Linux, BTW), and I want to know at any moment which hosts are connected to it. I recognize that it probably is the same thing as trying to know which hosts are connected to a lan, so any of the solutions might do the job... The fact is that I once used a hamachi vpn on linux and with it I had the chance to know which hosts were connected to a particular network where I belonged, so I was wondering if something similar might be possible in openVPN (or even any VPN and/or any LAN). Preferably, I'm looking for opensource/free sw solutions, or maybe the hints to program it myself (in the most simple way if possible, not that I don't know how to program, but I'm trying to achieve this in a simple manner). But anyway, if there are no os/fsw solutions, any other one might do... Thanks a lot! Javier, Mexico city

  • Best way to tackle global hotkey processing in c#?

    - by jeevan
    Hi all I'd like to have multiple global hotkeys in my new app (to control the app from anywhere in windows), and all of the given sources/solutions I found on the web seem to provide with a sort of a limping solution (either solutions only for one g.hotkey, or solutions that while running create annoying mouse delays on the screen). Does anyone here know of a resource that can help me achive this, that I can learn from? Anything? Thanks ! :)

  • Packing differently sized chunks of data into multiple bins

    - by knizz
    EDIT: It seems like this problem is called "Cutting stock problem" I need an algorithm that gives me the (space-)optimal arrangement of chunks in bins. One way would be put the bigger chunks in first. But see how that algorithm fails in this example: Chunks Bins ----------------------------- AAA BBB CC DD ( ) ( ) Algorithm Result ----------------------------- biggest first (AAABBB ) (CC ) optimal (AAACCDD) (BBB) "Biggest first" can't fit in DD. Maybe it helps to build a table like this: Size 1: --- Size 2: CC, DD Size 3: AAA, BBB Size 4: CCDD Size 5: AAACC, AAADD, BBBCC, BBBDD Size 6: AAABBB Size 7: AAACCDD, BBBCCDD Size 8: AAABBBCC, AAABBBDD Size 10: AAABBBCCDD

  • list of uids / names of System Preferences > Accounts

    - by neoneye
    How can I obtain an array with uid and names? I could iterate from 0 to 99999 and do a getpwnam(). However most machines have less than 5 accounts, so it's not optimal. I don't know what framework is responsible for this and thus I have no clue what to search for. Is there a more optimal solution that can traverse the accounts?

  • Sorting a list of numbers with modified cost

    - by David
    First, this was one of the four problems we had to solve in a project last year and I couldn’t find a suitable algorithm so we handle in a brute force solution. Problem: The numbers are in a list that is not sorted and supports only one type of operation. The operation is defined as follows: Given a position i and a position j the operation moves the number at position i to position j without altering the relative order of the other numbers. If i j, the positions of the numbers between positions j and i - 1 increment by 1, otherwise if i < j the positions of the numbers between positions i+1 and j decreases by 1. This operation requires i steps to find a number to move and j steps to locate the position to which you want to move it. Then the number of steps required to move a number of position i to position j is i+j. We need to design an algorithm that given a list of numbers, determine the optimal (in terms of cost) sequence of moves to rearrange the sequence. Attempts: Part of our investigation was around NP-Completeness, we make it a decision problem and try to find a suitable transformation to any of the problems listed in Garey and Johnson’s book: Computers and Intractability with no results. There is also no direct reference (from our point of view) to this kind of variation in Donald E. Knuth’s book: The art of Computer Programing Vol. 3 Sorting and Searching. We also analyzed algorithms to sort linked lists but none of them gives a good idea to find de optimal sequence of movements. Note that the idea is not to find an algorithm that orders the sequence, but one to tell me the optimal sequence of movements in terms of cost that organizes the sequence, you can make a copy and sort it to analyze the final position of the elements if you want, in fact we may assume that the list contains the numbers from 1 to n, so we know where we want to put each number, we are just concerned with minimizing the total cost of the steps. We tested several greedy approaches but all of them failed, divide and conquer sorting algorithms can’t be used because they swap with no cost portions of the list and our dynamic programing approaches had to consider many cases. The brute force recursive algorithm takes all the possible combinations of movements from i to j and then again all the possible moments of the rest of the element’s, at the end it returns the sequence with less total cost that sorted the list, as you can imagine the cost of this algorithm is brutal and makes it impracticable for more than 8 elements. Our observations: n movements is not necessarily cheaper than n+1 movements (unlike swaps in arrays that are O(1)). There are basically two ways of moving one element from position i to j: one is to move it directly and the other is to move other elements around i in a way that it reaches the position j. At most you make n-1 movements (the untouched element reaches its position alone). If it is the optimal sequence of movements then you didn’t move the same element twice.

  • Book with C programs that have real programming examples.

    - by Siamore
    This is my first question on Stack Overflow, I would like to know about any c programming books that have real programs to introduce real problems as opposed to standard books with examples aimed to teach the language it should be sort of like a challenge with solutions so that concepts like recursion can be used i know that i should find solutions to existing problems to learn the language but this is my first attempt and i find it hard to understand some simple problems so i was hoping for a book with solutions.

  • Increase samba space on open suse 12.1

    - by Kapil Sharma
    I know linux basics but not an expert. IT guy left the job here and there is some time before new hire. So sorry if question is very basic. We have local testing server based on Open SUSE 12.1, which also act as shared drive between dev/mgmt team here and using Samba for that. Now we are running out of space on samba, even though server's 2*1TB harddisk is nearly 90% free. My question is, what is limiting Samba and how can I increase its limit? We need around at least 500 GB as shared drive but currently its just 25 GB. I don't need step by step answer, just a link to any helpful article would be sufficient. Probably I'm putting wrong keywords in google so not getting any helpful link. EDIT: Output of commands in the first comment.

  • Setup access to SAS RAID drives with NTFS partitions on CentOS Machine

    - by Quanano
    We have a Dell Poweredge 2900 system with Adaptec 39320A SCSI CONTROLLER CARD and 4 SAS hard drives attached, with NTFS partitions on them. We installed CentOS on the other raid array with a different controller and it is working fine. We are now trying to access the drives shown above and they are not being shown in /dev as sdb, etc. sda is the drive that we installed centos on and it has sda1, sda2, sda3, etc. The CDROM has been picked up as well. If I scan for scsi devices then the perc and adaptec controllers are both found. sg0 is the CDROM and sg2 is the centos installed, however I think sg1 is the other drive but I cannot see anyway to mount the partitions, as only the drive is listed in /dev.

  • What is SharePoint Out of the Box?

    - by Bil Simser
    It’s always fun in the blog-o-sphere and SharePoint bloggers always keep the pot boiling. Bjorn Furuknap recently posted a blog entry titled Why Out-of-the-Box Makes No Sense in SharePoint, quickly followed up by a rebuttal by Marc Anderson on his blog. Okay, now that we have all the players and the stage what’s the big deal? Bjorn started his post saying that you don’t use “out-of-the-box” (OOTB) SharePoint because it makes no sense. I have to disagree with his premise because what he calls OOTB is basically installing SharePoint and admiring it, but not using it. In his post he lays claim that modifying say the OOTB contacts list by removing (or I suppose adding) a column, now puts you in a situation where you’re no longer using the OOTB functionality. Really? Side note. Dear Internet, please stop comparing building software to building houses. Or comparing software architecture to building architecture. Or comparing web sites to making dinner. Are you trying to dumb down something so the general masses understand it? Comparing a technical skill to a construction operation isn’t the way to do this. Last time I checked, most people don’t know how to build houses and last time I checked people reading technical SharePoint blogs are generally technical people that understand the terms you use. Putting metaphors around software development to make it easy to understand is detrimental to the goal. </rant> Okay, where were we? Right, adding columns to lists means you are no longer using the OOTB functionality. Yeah, I still don’t get it. Another statement Bjorn makes is that using the OOTB functionality kills the flexibility SharePoint has in creating exactly what you want. IMHO this really flies in the absolute face of *where* SharePoint *really* shines. For the past year or so I’ve been leaning more and more towards OOTB solutions over custom development for the simple reason that its expensive to maintain systems and code and assets. SharePoint has enabled me to do this simply by providing the tools where I can give users what they need without cracking open up Visual Studio. This might be the fact that my day job is with a regulated company and there’s more scrutiny with spending money on anything new, but frankly that should be the position of any responsible developer, architect, manager, or PM. Do you really want to throw money away because some developer tells you that you need a custom web part when perhaps with some creative thinking or expectation setting with customers you can meet the need with what you already have. The way I read Bjorn’s terminology of “out-of-the-box” is install the software and tell people to go to a website and admire the OOTB system, but don’t change it! For those that know things like WordPress, DotNetNuke, SubText, Drupal or any of those content management/blogging systems, its akin to installing the software and setting up the “Hello World” blog post or page, then staring at it like it’s useful. “Yes, we are using WordPress!”. Then not adding a new post, creating a new category, or adding an About page. Perhaps I’m wrong in my interpretation. This leads us to what is OOTB SharePoint? To many people I’ve talked to the last few hours on twitter, email, etc. it is *not* just installing software but actually using it as it was fit for purpose. What’s the purpose of SharePoint then? It has many purposes, but using the OOTB templates Microsoft has given you the ability to collaborate on projects, author/share/publish documents, create pages, track items/contacts/tasks/etc. in a multi-user web based interface, and so on. Microsoft has pretty clear definitions of these different levels of SharePoint we’re talking about and I think it’s important for everyone to know what they are and what they mean. Personalization and Administration To me, this is the OOTB experience. You install the product and then are able to do things like create new lists, sites, edit and personalize pages, create new views, etc. Basically use the platform services available to you with Windows SharePoint Services (or SharePoint Foundation in 2010) to your full advantage. No code, no special tools needed, and very little user training required. Could you take someone who has never done anything in a website or piece of software and unleash them onto a site? Probably not. However I would argue that anyone who’s configured the Outlook reading layout or applied styles to a Word document probably won’t have too much difficulty in using SharePoint OUT OF THE BOX. Customization Here’s where things might get a bit murky but to me this is where you start looking at HTML/ASPX page code through SharePoint Designer, using jQuery scripts and plugging them into Web Part Pages via a Content Editor Web Part, and generally enhancing the site. The JavaScript debate might kick in here claiming it’s no different than C#, and frankly you can totally screw a site up with jQuery on a CEWP just as easily as you can with a C# delegate control deployed to the server file system. However (again, my blog, my opinion) the customization label comes in when I need to access the server (for example creating a custom theme) or have some kind of net-new element I add to the system that wasn’t there OOTB. It’s not content (like a new list or site), it’s code and does something functional. Development Here’s were the propeller hats come on and we’re talking algorithms and unit tests and compilers oh my. Software is deployed to the server, people are writing solutions after some kind of training (perhaps), there might be some specialized tools they use to craft and deploy the solutions, there’s the possibility of exceptions being thrown, etc. There are a lot of definitions here and just like customization it might get murky (do you let non-developers build solutions using development, i.e. jQuery/C#?). In my experience, it’s much more cost effective keeping solutions under the first two umbrellas than leaping into the third one. Arguably you could say that you can’t build useful solutions without *some* kind of code (even just some simple jQuery). I think you can get a *lot* of value just from using the OOTB experience and I don’t think you’re constraining your users that much. I’m not saying Marc or Bjorn are wrong. Like Obi-Wan stated, they’re both correct “from a certain point of view”. To me, SharePoint Out of the Box makes total sense and should not be dismissed. I just don’t agree with the premise that Bjorn is basing his statements on but that’s just my opinion and his is different and never the twain shall meet.
