• How many ways a java Program can end ?

  - by Frank

  I know use System.exit(0) can end a java program, for instance, if I have a JFrame window, it will close and end the program, but I wonder how many other ways, can it be closed and the program be ended ? Including when an error occurs, will the program be shut down and the JFrame be closed ?

• When does a PHP script end?

  - by allyourcode

  In my mind, a web app something that runs continuously; therefore, I'm confused by documentation pages that talk about the "end" of a PHP script (eg this one). Such references seem to refer to the end of each web request, but if the script ends there, doesn't that mean that the OS has to setup a whole new process for each request? That seems unlikely, because spinning up a whole new process is expensive, and be very inefficient for the whole site.

  I have a link which animates some div's height when its hovered, but the div has a big height and it goes beyond the visible bottom-end of the screen. I have to scroll to see the data and when I scroll I leave the hover area and the div toggles it's height to 0px. How to automatically scroll to the end of the div when it toggles?

• Front-end developer interview questions

  - by peirix

  There are a lot of good interview questions (even "puzzles") for software developers here on SO, but I was wondering if anyone had some good questions for a front-end developer position. We're looking for someone who knows HTML+CSS+JS. Some of the obvious questions: Have you worked with javascript libraries (which?) Are you following the development of HTML5 and CSS3 Do you know any good "puzzles" for a front-end developer? Maybe a JS fizz-buzz?

  - by trobrock

  I have some code: - count = 0 - @clients.each do |client| %div{:class => "grid_2#{(" alpha" if (count % 3) == 0) || (" omega push_2" if (count % 3) == 2) || " push_1"}"}= link_to h(client.name), client - count += 1 I want to output an opening div tag right after the each statement if the (count % 3) == 0 and out put the end tag at the end of the block if the (count % 3) == 2 but I can't figure out how to get HAML to do this. Any ideas?

• static wsdl for a certain end point

  - by Costa

  Hi A certain EndPoint in a web service is not likely to change a lot, also it had a problem which we worked around by putting a static wsdl to the whole web service like this <serviceMetadata httpGetEnabled="true" httpGetUrl="" externalMetadataLocation="http://IP:8250/wsdl.xml"/> Now I want the rest of end points to have a wsdl dynamically created, and one end point which require a static WSDL. I think this is impossible because there is one WSDL per WCF service.

• how to find end of quarter given a date in the quarter

  - by Ramy

  If i'm given a date (say @d = '11-25-2010'), how can I determine the end of the quarter from that date. I'd like to use a timestamp one second before midnight. I can get this: select dateadd(qq, datediff(qq, 0, getdate()), 0) as quarterStart which gives me: '10-1-2010' and I use this for one second before midnight of a given day: select DateAdd(second, -1, DateAdd(day, DateDiff(day, 0, @d))+1, 0) ) AS DayEnd in the end, a quarterEnd method would give me '12-31-2010 23:59:00'

  Please, could you answer my question. How to remove digits from the end of the string using SQL? For example, the string '2Ga4la2009' must be converted to 2Ga4la. The problem is that we can't trim them because we don't know how many digits are in the end of the string. Best regards, Galina.

• Setting end-of-line character for puts

  - by Dom De Felice

  I have an array of entries I would like to print. Being arr the array, I used just to write: puts arr Then I needed to use the DOS format end-of-line: \r\n, so I wrote: arr.each { |e| print "#{e}\r\n" } This works correctly, but I would like to know if there is a way to specify what end-of-line format to use so that I could write something like: $eol = "\r\n" puts arr UPDATE I know that puts will use the correct line-endings depending on the platform it is run on, but I need this because I will write the output to a file.

• Unable to set password in IIS 8 for Domain User as ApplicationPool Identity

  - by Niels R.

  I'm trying to set a Domain User account as ApplicationPool Identity in IIS 8 (Windows 2012). When trying this using the IIS Management Console I always get an error: Value does not fall within the expected range. When trying to set the identity using appcmd.exe it fails on both the command setting the username and password or the command only setting the password. Setting the username is no problem. Trying to set both the username and password [FAIL]: >appcmd set config /section:applicationPools /[name='AppPoolName'].processModel.identityType:SpecificUser /[name='AppPoolName'].processModel.userName:DOMAIN\Username /[name='AppPoolName'].processModel.password:P4ssW0rd Applied configuration changes to section "system.applicationHost/applicationPools" for "MACHINE/WEBROOT/APPHOST" at configuration commit path "MACHINE/WEBROOT/APPHOST" ERROR ( hresult:80070057, message:Failed to commit configuration changes.

• Windows Server 2003 R2 Terminal Server : Internet Explorer Enhanced Security won't disable for Users

  - by Tubs

  The Internet Explorer Enhanced Security (IEES) won't disable using the normal method of disabling it from the Add/Remove Programs/Windows components. This came to light immediately after testing. IEES was disabled after Terminal Services were installed for admin and users, and after IE8 was installed. My initial thoughts were that there was some clash between IE8 and IE6 (which is the default on 2003 R2), so I uninstalled IE8 and reverted back to IE6. The same symptoms were displayed, when a normal user logged on Internet Explorer Enhnaced Security was enforced. I then thought it could be a problem that Terminal Server wasn't recognising the removal as IEES was on when initially installed. I uninistalled the Terminal Server Componants using the server roles, and then reactivated and deavtived IEES. Windows Server 2003 R2 allows a limited number of users to connect to RDP by default, so I logged on as a normal user, and IEES was disabled. I then reinstalled Terminal Server, and logged on as a normal user. IEES was back enabled. Why is this?

• Unicode paragraph end/line break breaking space / non breaking space aware text editor

  - by martinr

  I want one of those to write my blog articles with. I'm tired of manually converting breaks from rough notes to either paragraphs or line breaks for release as HTML, and tired of converting spaces to breaking or non-breaking ones. There are standard Unicode code points for the difference - what editor lets me use almost plain ASCII text but with builtin support and understanding for Unicode paragraph and non-breaking space characters? And ideally will let me save straight to either plain text UTF8 or to a file of plain HTML paragraphs?

• Apache2 URL Rewrite - Second-Level-Domain to the end of URL

  - by Acryl

  i have a site "example.com" and also many other domains like "example1.com", "example2.de", etc. I want that every Second-Level-Domain is rewritten in the following way: example.com/domainredirect=example1.com (when you open example1.com) and example.com/domainredirect=example2.de (when you open example2.de) So the original Second-Level-Domain should be rewritten after "example.com/domainredirect=" Thanks in advance

• Suggestions for programming language and database for a high end database querying system (>50 milli

  - by mmdave

  These requirements are sketchy at the moment, but will appreciate any insights. We are exploring what would be required to build a system that can handle 50 database million queries a day - specifiically from the programming language and database choice Its not a typical website, but an API / database accessing through the internet. Speed is critical. The application will primarily receive these inputs (about a few kb each) and will have to address each of them via the database lookup. Only a few kb will be returned. The server will be run over https/ssl.

• Can I change the user id of a user on one Linux server to match another server in /etc/passwd?

  - by user76177

  I have a Rails application that is on a virtual machine (RHEL 6) and it's database is on dedicated hardware (also RHEL 6). The app server has an NFS directory from the db server mounted and accessible. It needs to write images to that server that are uploaded via the app. Background processes on the db server need to read and write to the same directory, as they perform resizing operations on the uploaded files. Right now none of this is working, because the user ids are different between the two systems. I only need this to work for this one application, so it is way too much overhead to put an LDAP system in place. Can I simply change the user id of this one user in one of the systems, or will that cause mass chaos? UPDATE: The fix worked, at least on local devices. Unfortunately the device I have mounted to the main db server still thinks my user id is 502 instead of 506. Do I need to remount that device, or is there an NFS daemon I can stop and restart to refresh it?

• VSFTP Users and Directories

  - by Mathew

  I'm stuck. I've been working all day on trying to figure out what I'm doing wrong and I've hit wall after wall. What I'm trying to do: Setup FTP in such a way that certain users have access only to their directory, but higher level users have access to all directories. What I've Googled so far: I started with this, but that didn't do what I needed it to. I then used this, but once I created one user, it wouldn't let me create another one. Finally, I decided to follow this, but it wouldn't let me even create one user. I'm using Ubuntu 10. I can login to ftp as a root user and it takes me to the home directory. If I try to login using the user I created in the tutorial it says: Status: Connection established, waiting for welcome message... Response: 220 (vsFTPd 2.2.2) Command: USER mathew Response: 331 Please specify the password. Command: PASS **** Response: 530 Login incorrect. Error: Critical error Error: Could not connect to server

• Outlook users connected to exchange can email from other email accounts

  - by Sherriffwoody

  We have found an issue on our systems whereby an outlook user (both 2007 and 2010) connected to our Exchange server (2007) can send emails as other users using the following steps Within Outlook Click <New Email> Select the <From> button to show a list of accounts outlook contains, but it also shows the option Select<Other Email Address>. This brings up a small dialog box with another button which when selected allows the user to select an email from their contacts or the Active Directory. The user in most cases can select any email within the Active Directory and send an email as if it were coming from that selected email. It seems not everyone has this ability and I'm guessing it is something to do with settings in exchange or AD(version 6) or is there a group policy that can be implemented to stop users being able to do this. We have no idea what allows this and I have failed to find anything using Dr Google. No one has setup delegates within outlook but it does seem to be something similar? Does anyone know how to lock this down? Thanks in advance

• front end to linux std mailbox for development purposes

  - by Fabio

  I am actually a software developer, do have a fair amount of linux experience as a user though since 1997. I am normally on stackoverflow.com, please excuse me if this question isn't appropriate here. I am working on a web project. We send out emails. I work locally on a linux box. When coding I use my local mailboxes to check what's been sent. Emails sent out to valid email addresses are not arriving at my official mailbox; they might be stopped by the provider's mail servers (gmail, yahoo). Now, we are sending out HTML mails too. I need to check how they look like. Is there a GUI frontend to the standard linux BSD mailbox? Or should I install some IMAP/POP server for this? Will such server get the emails sent to username@localhost ? Thanks for any suggestion

• Performance of Virtual machines on very low end machines

  - by TheLQ

  I am managing a few cheap servers as my user base isn't large enough to get much more powerful servers. I also don't have the money lying around to invest in a server to prepare for the larger user base. So I'm stuck with the old hardware I have. I am toying with the idea of virtualizing all the current OS's with most likely VMware vSphere Hypervisor (AKA ESXi) Xen (ESXi has too strict of an HCL, and my hardware is too old). Big reasons for doing so: Ability to upgrade and scale hardware rapidly - This is most likely what I'll be doing as I distribute services, get a bigger server, centralize (electricity bills are horrible), distribute, get a bigger server, etc... Manually doing this by reinstalling the entire OS would be a big pain Safety from me - I've made many rookie mistakes, like doing lots of risky work on a vital production server. With a VM I can just backup the state, work on my machine, test, and revert if necessary. No worries, and no OS reinstallation Safety from other factors - As I scale servers might go down, and a backup VM can instantly be started. Various other reasons. However the limiting factor here is hardware. And I mean very depressing hardware. The current server's run off of a Pentium 3 and 4, and have 512 MB and 768 MB RAM respectively (RAM can be upgraded soon however). Is the Virtualization layer small enough to run itself and a Linux OS effectively? Will performance be acceptable (50% CPU overhead for every operation isn't acceptable)? Does it leave enough RAM for the Linux OS? Is this even feasible?
