  • Is there a language that allows this syntax: add(elements)at(index);

    - by c_maker
    Does a language exist with such a syntax? If not, what are some of the limitations/disadvantages to this syntax in case I want to write a language that supported it? Some examples: sort(array, fromIndex, toIndex); vs sort(array)from(index1)to(index2); Method signature would like this: sort(SomeType[] arr)from(int begin)to(int end){ ... } Update: Because there might be some confusion, I'd like to clarify... I meant this question as a general idea like this (not specific to sorting and possibly using keywords like from and to): In JAVA(like language): void myfancymethod(int arg1, String arg2){ ... } myfancymethod(1, "foo"); In imaginary language: void my(int arg1)fancy(String arg2)method{ ... } my(1)fancy("foo")method;

  • User input and automated input separation

    - by tpaksu
    I have a MySQL database and an automation script which modifies the data inside once a day. And these columns may have changed by an user manually. What is the best approach to make the system only update the automated data, not the manually edited ones? I mean yes, flagging the cell which is manually edited is one way to do it, but I want to know if there's another way to accomplish this? Just curiosity. BTW, the question is about cell values, not rows.

  • Having problem to login after upgrading from 11.10 to 12.04

    - by LinuxIsMyFriend
    I just update to 12.04 from 11.10 and I get to the login screen w/o problems. When I enter my password the screen turns black and returns to the login screen half a second later. There is a related question out there which was solved by creating more space on the disk but my disks (or rather partitions) are all below 30%. I can log in as guest. I can also login at the cmd prompt (going to tty with Alt+Ctrl+F1) with my normal user credentials. When logged in as guest I can also install programs using my normal account password. There is the normal authentication error when I mistype my password so I'm also sure the password works. Any suggestions?

You can learn more by visiting oracle.com/solaris, and our Oracle Technology Network Oracle Solaris 11.1 page. If you're at Oracle OpenWorld, be sure to attend Solaris engineering VP Markus Flierl's general session at 10:15 today, in Moscone South 103, where he'll be going into detail on Oracle Solaris 11.1 . And, be sure to sign up for our online launch event on November 7th, featuring Markus, fellow engineering VP Bill Nesheim, and a deep bench of Solaris engineers.

  • why opening a port is so difficult in ubuntu?

    - by icn
    I have searched around and I have run these commands iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 5432 -j ACCEPT iptables-save > /etc/iptables.rules And I rebooted the box. I had no luck. What am I missing? IS there a universal way to do this thing in ubuntu? I remember in fedora I just need to edit a text file and make it happen. Thanks UPDATE I have run ufw allow 5432 and I ran ufw status I got this result Status: active To Action From -- ------ ---- 5432/tcp ALLOW Anywhere 80 ALLOW Anywhere 22 ALLOW Anywhere 5432 ALLOW Anywhere 5432/tcp ALLOW Anywhere (v6) 80 ALLOW Anywhere (v6) 22 ALLOW Anywhere (v6) 5432 ALLOW Anywhere (v6) I still cannot access 5432!

  • Files Not Uploading

    - by Howdy_McGee
    So I'm running wordpress. I will make changes to theme files and upload them successfully but none of the changes show up on the actual website. At first I thought it was the wrong theme but I have specific theme files I created that are in there so I'm using the right theme. Then I thought it was a server problem and maybe the companies server are down so I checked a few other websites and updated information just fine. All on linux servers. Then I jumped to Wordpress to make sure it wasn't a wordpress problem but I can update the files fine from their Admin Panel. I checked to make sure it wasn't Filezilla Caches or Browser Caches so I cleared them both. What could be the problem? If it had to deal with the Filezilla client permissions I imagine I would get an error upon uploading but it uploads just fine. Suggestions would be extremely helpful I have no clue.

  • NetBeans 7.0.1 now in RC

    - by alexismp
    What would a GlassFish release be without a NetBeans version to go with it? The NetBeans team has released the NetBeans IDE 7.0.1 RC 1 which will bring full compatibility with JDK 7 as well as GlassFish 3.1.1 support (this particular RC ships with the soft code freeze build of GlassFish 3.1.1). This 7.0.1 RC 1release also includes numerous bugfixes and performance improvements across all areas and is available from the usual download page and the final version of NetBeans IDE 7.0.1 is expected in late July (once JDK 7 has shipped would be an educated guess). Note that if you're an existing NetBeans 7.0 user you'll be offered with updates to your existing install via the Update Center once 7.0.1 final ships.

  • Working in America from the UK

    - by thedixon
    I've been toying with the idea for the last few years and I figured it was about time to start asking questions about it! Here goes: I'm a Senior-level .NET/C# programmer from the UK, with 7 years of commercial experience in industry and looking to work over across the pond in the big ol' USA! This is with a view to live there on a permanent basis. My idea is to try and set up some interviews and go over there for a week to attend them, then I guess wait for responses in hopes they'd sponsor me for a working VISA. I'd like to know is there anyone out there with any experience of doing the same thing? Was it difficult finding work? Is there anything I should know before embarking on this route? How long did the transition take? Update: Considering the down votes, either I've posted this in the wrong place, or people really don't like my query. If so, please shed some light.

  • Wireless mouse temporarily freezes when resume from standby

    - by R Pennese
    I have been getting a very annoying problem since recently in Ubuntu 12.04, probably due to another update that did more bad than good... When I resume from sleep on my Lenovo Thinkpad T420, my wireless laser mouse (Logitech M705) freezes at regular intervals (15.20 seconds) for 5 seconds then works again. This happens regardless if the computer is on battery or on AC power. How do I debug this? I am getting tired of the fact that my system gets more and more unstable over time while it should be the opposite...

"sudo rfkill unblock all" This will unblock all hardware ports. that's it!!!!!! :) It works,..

  • Simulating a sine wave/oscillating pattern for enemies

    - by Sun
    I'm creating a simple top down shooter, right now I have an enemy which simply follows the player. I'd like to change things up and have the enemies move towards the player but in a wave like motion. I have looked at some similar questions like this but they don't take into account for the Y changing. How can I simulate a wave like pattern for my enemies whilst they are homing into their target. Edit: Sample code In my update method I have the following: Vector2 trackingPos = position - target; trackingPos.Normalize(); position -= trackingPos * elaspedTime * speed;

  • 12.04 Login gone wrong

    - by Mark H
    I seem to have a fault in the login procedure somewhere. When I boooted up I found that if I selected Guest I could use the computer. If I selected my administrator account I was taken straight to the terminal. So I opened a guest session, went to user settings, and unlocked my admin account (it accepted the password!), and amended it to show "password None" and automatic login. I now find that when I boot up I am taken straight to the terminal - if I exit terminal I get the login screen - if I select the administrator login I go back to terminal - if i select guest I can use the PC, and if I select mu normal user account I can use the PC. So I cannot login as an administrator - so admin functions such as update are no longer accessible. Sorry to be so long winde but I am stuck. Can anyone suggest anything - I am a beginner with this

  • Do I need to add an index on a table with one row?

    - by briddums
    I'm creating a parameter table in our database. This table will have 1 row with values that are environment specific (production, development, etc). Is there any reason why I should define an index on this table? Update This table is a parameter table which will be used to drive our job queue system. The table will be defined like this: QueuePrm LogLvl integer ShowMs boolean Restart boolean This table will only ever have 1 row. No other table in our system will reference it.

  • Portable website

    - by johnny_s
    I have an online presentation to do next week and I have it all ready to go. The website is HTML and CSS only (no DB), and currently resides on my shared hosting account. Now, although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives: Host my site on two different domains or servers (but what about the domain name?) Have a portable XAMPP version on a USB stick (again, domain name?) Possible failover site/location Update The presentation will be carried out on their laptop, not mine. So I am unable to install any software.

  • Implementing hitbox polygon

    - by Delusional Logic
    I'm creating a shooter, it's still very early, but i'm implementing some polygon hitboxes. So far i have created a polygon class, and i'm looking into how i can hook it onto my player. I'm trying to stay away from having a Tick() function in my polygon class, and I would rather not update the position every tick (it would clutter up my tick functions). At the same time I would really like to have the positions in there somehow (it has a drawing function, and i will be using it for hit detection) How would i go about implementing this polygon object into my entities?

  • How to deal with a ten days debugging session? [on hold]

    - by smonff
    Ten days ago, I fixed a bug on a large application and the hot fix has created a disappearing of some data from the user point of view. Data are not deleted, but have been set to hidden status. It could be possible to get the data back, but the thing seems to be hard: I've already spent 10 days to understand and reproduce the problem (mostly with complex SQL queries but sometimes it is necessary to update the database to test the application logic). Is 10 days a normal amount of time for these kind of problems? Should we keep on and retrieve the data or should we tell these users sorry for the loss, but your data have disappeared? Any advice on when to stop searching how to solve the issue?

  • Weird graphical bug when installing on an Asus G51jx

    - by skeletons
    Each and every time I attempt to install ubuntu 11.04 or 11.10 I get this bug after the very first ubuntu loadscreen pops up from the boot cd. I have been able to successfully load 10.04 and 10.10 on it but it refuses to load 11.10. Even attempting to update from 10.10 to 11.04 caused this very same issue. I am running on an Asus G51jx. Please help I have been trying to get this working for two weeks now. I do like 10.10 but I would rather have 11.10 :(

  • What is causing Unity to be slow on startup?

    - by To Do
    A few days ago I noticed that after I login in, the top panel and the dash took a bit more time to load and I noticed more disc activity than usual. I thought that it might have been caused by some update or by the installation of pdftk. So I removed pdftk but the "problem" persists. Is there a way to know what is using the disc (read/write operations) on startup? If it were at a later time, I would use iotop but I can only launch iotop after I get control of the desktop. I'm on Ubuntu 12.10 amd64.

  • SQL Server Requery() sometimes hangs

    - by PSU
    I have an issue with Visual C++ and Microsoft SQL Server 2008R2. The following code will occasionally hang: Object->Update(); if(Object->CanRestart()) { //Why does this not return?? m_pDBRoRBaseObject->Requery(); } Object is derived from CRecordset. It looks to me as though a call to ::SQLExecute(m_hstmt) in the Requery() method is hanging, but I can't (with my current skill set anyway) figure out a way around this. Has anyone had a similar problem, or an insight of any sort?

  • Game Database Connectivity Java

    - by The Kraken
    I'm developing a simple multi-player puzzle game in Java. Both players should be able to view the same game board on his own computer. Then, when one player makes an action in the game (ex. drags an object onto a coordinate space), the game's view should update automatically on the other computer's game screen. I'd like all this to happen over the internet, not requiring both computers to be on the same LAN connection. If I need to use SQL/PHP to accomplish this, I'm unsure how to design the database to accomplish something as simple as the following: Player A drags element onscreen Game sends coordinates of element to database/server Player B's computer detects a change to an item in the database Player B's computer grabs the coordinates of Player A's item Player B's machine draws onscreen elements at the received coordinates Could somebody point me in the right direction?

  • Screen rendering problems after upgrading to 12.10

    - by vjrj
    Since upgrading to Ubuntu 12.10 I'm suffering severe rendering issues in unity: Some parts of any application (for instance Firefox, or emacs, etc) are blank, or are not rendered, or are blinking. Some fonts in an application are not correct rendered, maybe only some part (see Eclipse screenshot). There is some shadows in desktop background. It's something that occurs from time to time (it's works great for hours and suddenly start to give this rendering problems). I was trying to find a bug in launchpad but without success. My card (using i915 module): 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0042] (rev 02) I've tried to reset compiz/unity or gnome but does not help. Any tip? Update: A Firefox screenshot of how my profile in Ask Ubuntu looks like now
