  • Rollback in Oracle and SQL Server

    - by CatherineRussell
    I have an Oracle background. It was interesting to see how rollback handled in Oracle and SQL Server. There is no begin trans in Oracle.  What oracle does is it will store the data in a temporary area called the rollback segments. Untill your issue the commit command the records will be kept there. You can even rollback your update statement by issuing the rollback command. When you issue the commit command the records in the rollback segments are written to the redo log files. The same logic for insert is also applicable except that there is no mirror image of the record kept.   In SQL Server, if you want to be able to roll back statement, you neet to start your statement with a "begin tran" . Then, you can rollback a transaction, if this is needed. begin tran update Person set FirstName = 'Arthur' where PersonId = 10 -- select firstname from Person rollback

  • University teaches DOS-style C++, how to deal with it

    - by gaidal
    Half a year ago I had a look at available programming educations. I chose this one because unlike most of the choices: The majority of the courses seemed to be about something concrete and useful; the languages used are C++ and Java which are platform-independent; later courses include developing for mobile devices and a course on Android development, which seemed modern and relevant. Now after two introductory courses we're just starting with C++, and my programming professor seems a bit weird. He's tested us on things like "why should you use constants" and "why are globals bad" in a kind of mechanical way, without much context, before teaching actual programming. His handouts use system("pause"), system("cls"), and getch() from some conio.h that seems ancient according to what I've read. I just did a task that was about printing the "ASCII letters from 32 to 255" (huh?), with an example picture showing a table with Windows' Extended ASCII - of course I got other results for 128-255 on my Arch Linux that uses Unicode, and this isn't mentioned at all. I don't know, it just doesn't seem right... As if he is teaching programming because he has to, perhaps? Should I bring such things up? Hmm. I was looking forward to learning from someone who really knows stuff, and in an academic, rigorous way, like SICP or something. Aren't professors in programming supposed to be like that? I studied math for a while and every teacher and assistant there were really precise about what they said, but this is my second programming teacher that is sort of disappointing. Oh well. Now, question: Is this what to expect from universities or Not OK, and how do I deal with it? I have never touched the language C++ (or C) until now, and am not the right person to jump up and say "This is So Wrong!", so if I google something and find 10 people who say "xxx is blasphemy", how do I skillfully communicate this? I do think it would be better for those classmates who are total beginners not to learn bad habits (such as these vibes of total ignorance of other platforms!) during the upcoming courses, but don't want to disrespect the teacher. I don't know if it's reasonable or just cocky to bring up things like "what about other platforms?" or "but what about this article or stackoverflow answer that I read that said..." for every assignment? Or, if he keeps ignoring non-Windows-programming, should I give up and focus on my own projects or somehow argue that this really isn't OK nowadays? Are there any programming teachers out there, what do you think? By the way these are web-based courses, all interaction between teachers and students takes place in a forum. EDIT: A few answers seem to be making some incorrect assumptions, so maybe I should add a few things. I have been doing programming for fun on and off for 10 years, am pretty comfortable in 3 languages and read programming blogs et c regularly. Also, I feel kind of done being a student, having a degree in another field. I just need another, relevant diploma to work as a programmer, so I'm going back for that. Studying computer science for 5 years is not for me anymore, even though I enjoy learning and solving problems in my free time. Second, let me highlight that I don't expect it to be like the industry at all, quite the contrary. I expect it to be academic, dry and unnecessarily correct. No, it's not just math. Every professor I have had in math, or Japanese (major) or Chinese (minor) have been very very academic, discussing subtle points for hours with passion. But the courses I'm taking now and a previous one in programming don't seem serious. They neither resemble industry NOR academia. That is the problem. And it's not because I can't learn programming anyway. Third, I don't necessarily want to learn C++ or Android development, and I know I could teach myself those and anything else if I wanted to. But I am going back to school anyway, and those platform-independent languages and mobile stuff made me think that maybe they're serious about teaching something relevant here. Seems like I got this wrong, but we'll see.

  • Is it possible to install Ubuntu 10.10 and/or Ubuntu 11.04 on a late 2009 iMac?

    - by Oliver
    I would like to install Ubuntu on my iMac 10,1 (21.5 inch display). I would prefer to instal Natty Narwhal, but would surely settle for Maverick Meerkat (which I have a install dvd of). I have an install of OS X Snow Leopard AND a Bootcamp Partition of Windows 7. I would like to keep all these partitions and setup a triple boot system. If it can work, I'm also wondering if it'd be safe to install all updates from the update manager once it's installed. Thank you in advance. :)

  • Futures/Monads vs Events

    - by c69
    So, the question is quite simple: in an application framework, when performance impact can be ignored (10-20 events per second at max), what is more maintainable and flexible to use as a preferred medium for communication between modules - Events or Futures/Promices/Monads ? Its often being said, that Events (pub/sub, mediator) allow loose-coupling and thus - more maintainable app... My experience deny this: once you have more that 20+ events - debugging becomes hard, and so is refactoring - because it is very hard to see: who, when and why uses what. Promices (i'm coding in javascript) are much uglier and dumber, than Events. But: you can clearly see connections between function calls, so application logic becomes more straight-forward. What i'm afraid. though, is that Promices will bring more hard-coupling with them... p.s: the answer does not have to be based on JS, experience from other functional languages is much welcome.

  • nut (UPS) and SSL certificates

    - by Mausy5043
    Today I installed nut on my Ubuntu server (14.03). $ uname -a Linux boson 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux The UPS is connected to another server (called neutron), so I use nut-client to keep tabs on the UPS state. When I do sudo upsc [email protected] I get: Init SSL without certificate database battery.charge: 15 battery.charge.low: 10 battery.charge.warning: 50 battery.date: not set battery.mfr.date: 2012/11/27 : The first line of the output concerns me. I've not seen this on other installations of nut on Debian-based servers. What can I do to get rid of that line? EDIT: This "Init SSL without certificate database" is extra annoying because it is not part of the output of upsc and therefore I cannot grep it out.

  • Duplicate domain names - .net and .com Create separate pages, or redirect?

    - by guisasso
    In a SEO point of view: This website has a good amount of traffic for a local business, but also ships some merchandise. While the .net domain (registered first) is associated with the local busines (google places, maps, etc...) the .com domain only redirects to the .net domain. Is it good, bad or okay to create a different page for the domain .com for example, that would be pretty simple, but would link to the 10 different categories of products that this company sells? I know links are good, so there's that, but what else is good, or bad? Thanks in advance!

  • Options for Application Registry

    - by Matt Felzani
    I work for a small software company (about 200 people building 8-10 applications) and I was hoping to get some advice on products that might be out there to manage the information of which clients are using which versions of our products? The most fundamental relationship would be that a "product" has "versions" and a given "version" is used by a "client." Uses would be: Determine which clients use which products Determine which clients are on which versions of a product Determine which clients are exposed to which vulnerabilities because of the version they use Determine which clients cannot move to a new version because of a vulnerability in the new version that they may hit Determine which clients should be approached for an upgrade Any thoughts or product reviews would be greatly appreciated! Thanks in advance.

  • Can't start x session after updating packages

    - by chaos
    I have recently upgraded to 12.04 and all seems ok except adobe flash plugin doesn't work. But one several days ago when I installed several update packages and rebooted the x session was unable to start and it automatically switches to console 1 for commandline login. What's frustrating is there's essentially no error messages when I click alt+F7 to see what's going on with the x session. There are a bunch of [ok]'s and the last line seems to be something like 'starting x font server' and it just hang there. The closest thing to an error is something like 'stopping system V compatability (*words I can't remember*) ... [ok]'. This is nearly the most frustrating experience I've ever had with linux in the past 10 years. Can anyone help me?

  • How can i fit 2 commands in 1 terminal shortcut

    - by Nicky Bailuc
    10 latest updates and drivers and I need to run a game called unreal tournament, but in terminal it requires 2 commands The first one is to mount into the folder: cd /usr/local/games/ut2004/ and then the second one is to open the actual game: sudo aoss ./ut2004 In one shortcut i can only fit 1 command but both don't fit in is there any way i can turn these 2 commands into one? Perhaps turni9ng on the desktop shortcut already mounted into the folder? Any help would be really appreciated because im getting kinda sick of using the terminal to run it every time.

  • Blocking path scanning

    - by clinisbut
    I'm seeing in my access log a number of request very suspicious: /i /im /imaa /imag /image /images /images/d /images/di /images/dis They part from a known resource (in the above example /images/disrupt.jpg). All comming from same IP. Requests varies from 1/sec to 10/sec, seems somewhat random. It's obviously they are trying to find something and seems they are using a script. How do I block this kind of behaviour? I though of blocking the IP request, at least for a given time. Keeping in mind that: Request intervals seems legitimate (at least I think so). I don't want to end blocking a search engine bot, which may find 404 urls too (and that's a different problem, I know). ¿Do they use always same IP?

  • How to implement the setup rules like Clash of Clan?

    - by user25959
    Now I'm already implement the setup build rules which the building could move by unit grid width and height. But the validation detection is poor efficiency. The algorithm cost me 10~12(ms) in average when I move the building. Here is my approach to that: 1.Basic Grid, it is a two dimensional array. Grid[row][column], so that I can save info for each grid. Like whether is it in occupied or excluded. 2.Exclude Space, this is a space which limit same building numbers in space.

  • How to suppress "Card not present / present" spam in syslog?

    - by vava
    I'm getting a lot of Dec 27 08:35:49 htpc kernel: [ 1552.153797] pciehp 0000:00:1c.5:pcie04: Card not present on Slot(0-2) Dec 27 08:35:49 htpc kernel: [ 1552.157744] pciehp 0000:00:1c.5:pcie04: Card present on Slot(0-2) messages in my syslog, about 10 every second. That just makes syslog unusable, can I somehow get rid of them? I don't know and don't really care about the reason of those messages being there, partly because my motherboard doesn't have pcie slots on it and partly because everything I care about works perfectly. That might be a WiFi chip I disabled in bios but hey, I don't want wifi to be powered on, I'm not using it. So can I just suppress those messages?

  • UEC - Unable to SSH into instance, asks for password

    - by nijanthanh
    I am attempting to set up a private cloud using Ubuntu 10.04.4 Server. I am following the tutorial at http://cssoss.wordpress.com/2010/11/26/eucabook-v1-1/ . All steps go on perfectly apart from that I am unable to SSH into the running instances. I have created the instance using a public key and try to SSH into instance using the private key. However it asks for password. I am able to ping the instance though. I have tried using both the pre-built images from the store as well as custom built images. Several people seem to have the same problem but there does not seem to be any working solution. Thanks in advance.

  • Simple 2D Flight Physics with Box2D

    - by MarkPowell
    I'm trying to build a simple side scroller with an airplane being the player. As such, I want to build simple flight controls with simple but realistic-feeling physics. I'm making use of cocos2D and Box2D. I have a basic system working, but just can't get the physics feeling correct. I am applying force to the plane (which is a b2CircleShape) based on the user's input. So, basically, if the user pushes up, body_->ApplyForce(b2Vec2(10,30), body_->GetPosition()) is called. Similarly, for down -30 is used. This works and the plane flys along with up/down causing it to dive or climb. But it just doesn't feel right. There is no slowdown on climbs, nor speed up during dives. My simple solution is far to simple. How can I get a better feel for a plane climbing/diving? Thanks!

  • NHibernate Pitfalls: Private Setter on Id Property

    - by Ricardo Peres
    Having a private setter on an entity’s id property may seem tempting: in most cases, unless you are using id generators assigned or foreign, you never have to set its value directly. However, keep this in mind: If your entity is lazy and you want to prevent people from setting its value, make the setter protected instead of private, because it will need to be accessed from subclasses of your entity (generated by NHibernate); If you use stateless sessions, you can perform some operations which, on regular sessions, require you to load an entity, without doing so, for example: 1: using (IStatelessSession session = factory.OpenStatelessSession()) 2: { 3: //delete without first loading 4: session.Delete(new Customer { Id = 1 }); 5:  6: //insert without first loading 7: session.Insert(new Order { Customer = new Customer { Id = 1 }, Product = new Product { Id = 1 } }); 8:  9: //update without first loading 10: session.Update(new Order{ Id = 1, Product = new Product{ Id = 2 }}) 11: }

  • VirtualBox Port Forward

    - by john.graves(at)oracle.com
    A great new feature in VirtualBox 4.0 is the ability to use NAT networking and forward ports without needing to use ssh -L/-R tricks.  This is great for booting multiple VM domains simultaneously.  It is possible to have several instances which map back to the host machine and different ports on localhost:* automatically forward to the correct VM.  This avoids the hassle of setting up dns entries or static IP addresses.In this example, I'm mapping the host ports 3xxxx to the VM's well known server ports.Note: It is important to setup the Frontend HTTP host/port to avoid incorrect URL rewriting.You may also need to setup an http channel to deal with local traffic which uses the network address 10.0.2.15Happy VMing.
