  • PHP, better to set the variable before if or use if/else?

    - by DssTrainer
    So a simple one that I just never could find a straight answer on. What is better (performance or otherwise): $var = false; If ($a == $b) { $var = true; } or If ($a == $b) { $var = true; } else { $var = false; } I've heard arguments for both ways. I find the first cleaner to ensure I have it set, and a little less code too. The pro being that you may only need to set it once without conditional. But the con being that if the argument is true, it gets set twice. I am assuming the second way is probably best practice

  • How to set the focus on the first <select> element of the page using JQuery?

    - by user605660
    Hi. I would like to set the focus on the first element of the page using JQuery when the page is loaded. I could successfully set the focus for first element by using $(":input:visible:first").focus(); or $(':input:enabled:visible:first').focus(); , according to jquery, set focus on the first enabled input or select or textarea on the page . I tried to use something like $('select:first').focus(); or $("select").first().focus(); or $(':visible:first').focus(); or $('enabled:visible:first').focus(); or other variations I could think of, but have not succeeded. Could anyone help me on this problem? I am a beginner for JQuery. I would like this function to work for all major browsers. Thank you very much!

  • How to code the set method of a Map with another Map as value?

    - by Nazgulled
    I normally do this to set a new Map to a private variable: public static void setListaClausulas(Map<String, Clausula> nvLista) { listaClausulas = new TreeMap<String, Clausula>(nvLista); } I suppose this is ok to set a new copy of the nvLista and all it's members and not a reference, is it? But now I have a Map inside another Map and I'm doing this: public static void setListaClausulas(Map<String, Map<String, Clausula>> nvLista) { listaClausulas = new TreeMap<String, Map<String, Clausula>>(nvLista); } Is this the correct way to do it or do you recommend something else? What I want is to set a new copy of nvLista (and all it's elements) and not copy just the reference.

  • Can you set up a gaming LAN using OpenVPN installed in a VMware guest OS and be playing the game on the host OS?

    - by Coder
    I would like to setup a gaming VPN. Ie. I have some games that work over LAN and would like to play them with people that are not on my LAN. I know I can do this with OpenVPN. My ultimate goal would be to run OpenVPN portably on my host OS and not even need any virtualization. As such i don't want to install it on my host, but i'm fine with running it portably. I'm even fine with temporarily adding registry keys, and then running a .reg file to remove these entries once i'm done. To this effect i have installed OpenVPN on a virtual machine and diffed the registry. I then manually (using a .reg file) added all the keys that seem important on my host OS and copied the installation folder of OpenVPN onto my host machine. Then i try to run openVPN GUI 1.0.3 as a test and it says "Error opening registy for reading (HKLM\SOFTWARE\OpenVPN). OpenVPN is probably not installed". I verified that that key is indeed in the registry with all subkeys and it looks correct. I have tried running the GUI as an administrator and in compatibility mode with no success. I am running Windows 7. If this fails then i would be happy with installing OpenVPN on a virtual machine in VMWare but they key is that i will be running the game installed on my host machine. The first question for this option is if this is even possible. The second is, that I can't get the VM to have internet access if I use bridging but i can if i use NAT. Is it possible to do this game VPN setup with VMWare guest OS running using NAT? Summary of questions: -Is it possible to run openVPN portably and if so what did i miss above? -If it's not possible to run it portably, then can setup a gaming LAN by installing OpenVPN in a guest OS with NAT and how can i do this? -If the above is not possible then can i install OpenVPN in a guest using bridging and if so how can i set this up with a Windows 7 host and Windows XP guest as currently i can't get the guest to be able to access the internet in bridging mode, but it working in NAT mode. -In general is there any good documentation on setting up a gaming LAN with OpenVPN (i am using 2.1.4) as i have never set up a VPN of any sort before so any help would be much appreciated. Thanks!

  • Is it possible to set the date on a Linux machine to the year 2040?

    - by Daryl Spitzer
    I need to be able to set the date on Ubuntu (8.04.4 LTS) to the year 2040 (to test something that isn't relevant to this question). Is that possible? I can run: $ sudo date -s "15 JAN 2038 18:00:00" Fri Jan 15 18:00:00 PST 2038 ...but: $ sudo date -s "15 JAN 2039 18:00:00" date: invalid date `15 JAN 2039 18:00:00' Is the limit somewhere in 2038 (or prior to Jan. 15, 2039)? Does this change with different versions of Linux?

  • Why do I need to set up Autologon values in registry twice in before it works and can I fix this?

    - by jJack
    Background: As part an automated testing suite I am building, I need to set up Autologon on my virtual machines 'on demand'. By on demand, I mean that I don't want to necessarily pre-configure my VM or any snapshot to have Autologon set up already, for security reasons and also a huge business case. My solution so far: I'm copying a script to the guest machine and then using Sysinternals PsExec to execute it. The script is: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultUserName /t REG_SZ /d myusername reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultPassword /t REG_SZ /d myfakepassword reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultDomainName /t REG_SZ /d mydomain reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v ForceAutoLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v AutoAdminLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoLogonChecked" /f /ve /d 1 Note: I don't believe AutoLogonChecked is required for machines post Windows 2000 but I'm doing it just in case for now. Maybe ForceAutoLogon isn't either, not sure yet. The Problem: I see PsExec executes this properly and all the values are in the registry, however when I restart the machine, the user isn't automatically logged on...When I run this a second time then restart the machine, the user is finally logged on. A diff between the registry states shows that the first time I run this, it is missing both the "1" for AutoAdminLogon, and also the DefaultPassword key. The second time I execute it, these values are correctly intact as I intended. So, what is going on here? Is this expected? This post claims in the end that it really all just works (the problem was that a logoff script was setting off the values). Doesn't seem to work for me however. Note this seems unique to Windows 7, does not occur in Windows XP Also note that you don't need PsExec to recreate the issue - just modify the registry yourself EDIT/update: Login interactively and run script (so, not executing it remotely), logging off automatically logs me back in (so, it works) remotely execute the script in guest when I'm interactively logged in, logging off automatically logs me back in (so, it works) remotely execute the script in guest when with non-interactive session if I log in afterwards (so, interactive now) then back off, it logs me back in (so, it then works) EDIT/update 2: This only occurs for Win7x86, Win7x64, Win8x64. This does not occur for Windows XP

  • In Apache, how do I set up password protection?

    - by rphello101
    I'm attempting to set up a server using Apache. In the conf file, I inserted the code: <Directory /> Options FollowSymLinks AllowOverride AuthConfig AuthType Basic AuthName "Restricted Files" AuthBasicProvider file AuthUserFile C:\...\serverpass.txt Require user Admin </Directory> In order to try and get Apache to require a password. I created the username and password with htpasswd -c. When I got to localhost though, it doesn't prompt me for a username and password?

  • How do I set advanced file associations in Windows 7?

    - by Dan O
    It used to be in Windows XP that I could make Warcraft III files load automatically into the game by double clicking on them. This association was made by going to file associations ADVANCED area and using this line: "C:\Program Files\Warcraft III\War3.exe" -loadfile "%1" Note that it takes an argument and an option. However, in Windows 7, the "Default Programs" "Set Associations" area doesn't seem to have this advanced area. Can I still get these files to open automatically?

  • Is it possible to quickly set all spaces to the same wallpaper?

    - by LBRapid
    It's great that Lion allows different spaces to have different wallpapers, but I have not found an easy way to get them all to use the same wallpaper. The only way I've accomplished it so far is to either manually change the wallpaper for each space or to close all of the spaces (except the one that has the wallpaper I want) and reopen them. Anybody have a solution to allow me to quickly set all spaces to the same wallpaper?

  • How do you set up SSL and Nginx Proxying?

    - by Jason Christa
    I have Nginx listening to traffic on port 80 and proxying certain request to Apache over port 8080. I am going to set up Nginx to listen to port 443 for https traffic, but my question is how should the proxying be done now? Does the proxy to Apache need to be https or has Nginx already decoded it so I can keep sending it to Apache over port 8080. BTW, Apache is running with the least amount of modules installed possible and has currently has no SSL related modules, would I need to install any?

  • Used SQL Svr 2008 Config Manager to Set Service Account to Local System: What Did It Change?

    - by Frank Ramage
    Direct shot to foot moment... While setting-up individual non-admin accts for MSSQLSERVER services, I temporarily set Server service login to Local System account. I remembered later that: SQL Server Configuration Manager performs additional configuration such as setting permissions in the Windows Registry so that the new account can read the SQL Server settings. I want my Local System back . (Actually just restored to its original security profile) Any advice? Thanks!

  • I need to set-up the blocked machine to relay to the unblocked machine using a different port

    - by Zain Ally
    I have two Windows Server 2003 machines sitting in a network. Server B has port 25 open and can relay emails to the local network's smtp server. Server A does not have port 25 open. How can I set it up to send emails through another port to the SMTP server? I am thinking if I can setup a local SMTP communication between my servers on a different port and let Server B send Server A's emails. Is that possible?

  • Good maintained privacy Add-On/settings set that takes usability into account?

    - by Foo Bar
    For some weeks I've been trying to find a good set of Firefox Addons that give me a good portion of privacy/security without losing to much of usability. But I can't seem to find a nice combination of add-ons/settings that I'm happy with. Here's what I tried, together with the pros and cons that I discovered: HTTPS Everywhere: Has only pro's: just install and be happy (no interaction needed), loads known pages SLL-encrypted, is updated fairly often NoScript - Fine, but needs a lot of fine-tuning, often maintained, mainly blocks all non-HTML/CSS Content, but the author sometimes seems to do "untrustworthy" decission RequestPolicy - seems dead (last activity 6 months ago, has some annoying bugs, official support mail address is dead), but the purpose of this is really great: gives you full control over cross-site requests: blocks by default, let's you add sites to a whitelist, once this is done it works interaction-less in the background AdBlock Edge: blocks specific cross-site requests from a pre-defined whitelist (can never be fully sure, need to trust others) Disconnect: like AdBlock Edge, just looking different, has no interaction possibilities (can never be fully sure, need to trust others, can not interact even if I wanted to) Firefox own Cookie Managment (block by default, whitelist specific sites), after building own whitelist it does it's work in the background and I have full control All These addons together basically block everything unsecure. But there are a lot of redundancies: NoScript has a mixed-content blocker, but FF has it's own for a while now. Also the Cookie blocker from NoScript is reduntant to my FF-Cookie setting. NoScript also has an XSS-blocker, which is redundant to RequestPolicy. Disconnect and AdBlock are extremly redundant, but not fully. And there are some bugs (especially RequestPolicy). And RequestPolicy seems to be dead. All in all, this list is great but has these heavy drawbacks. My favourite set would be "NoScript Light" (only script blocking, without all the additonal redundant-to-other-addons hick-hack it does) + HTTPS Everywhere + RequestPolicy-clone (maintained, less buggy), because RequestPolicy makes all other "site-blockers" obsolete (because it blocks everything by default and let's me create a whitelist). But since RequestPolicy is buggy and seems to be dead I have to fallback to AdBlock Edge and Disconnect, which don't block all and and need more maintaining (whitelist updates, trust-check). Are there addons that fulfill my wishes?

  • Anyone know of a utility to print a set of similar web pages?

    - by Umber Ferrule
    I need to print potentially a couple of hundred letters (formatted web pages) which are automatically generated by another system. I'm looking for something that I can point at a directory containing these web pages, set the print options once and then it will print them all without any further intervention or messing about. Preferably free. Windows (XP onwards).
