  • What is the best practice when using UIStoryboards?

    - by Scott Sherwood
    Having used storyboards for a while now I have found them extremely useful however, they do have some limitations or at least unnatural ways of doing things. While it seems like a single storyboard should be used for your app, when you get to even a moderately sized application this presents several problems. Working within teams is made more difficult as conflicts in Storyboards can be problematic to resolve (any tips with this would also be welcome) The storyboard itself can become quite cluttered and unmanageable. So my question is what are the best practices of use? I have considered using a hybrid approach having logical tasks being split into separate storyboards, however this results in the UX flow being split between the code and the storyboard. To me this feels like the best way to create reusable actions such as login actions etc. Also should I still consider a place for Xibs? This article has quite a good overview of many of the issues and it proposes that for scenes that only have one screen, xibs should be used in this case. Again this feels unusual to me with Apples support for instantiating unconnected scenes from a storyboard it would suggest that xibs won't have a place in the future but I could be wrong.

  • What is the potential for a FUSE mount to destabilize a Linux server?

    - by 200_success
    I'm a sysadmin for a multi-user server, where students in our department have shell accounts. One of our users has requested that we install sshfs on it. I'm debating whether it would be wise to install sshfs as suggested. My main concern is whether a FUSE mount could make our server less reliable. In my experience, bad things can happen to servers when an NFS server suddenly becomes unavailable — the load average shoots up, and you might not be able to unmount it cleanly, to the point where a hard reboot might be necessary. If a FUSE-mounted server suddenly disappears, how hard might it be to clean up the mess? Are there any other likely catastrophes or gotchas I should consider? At least with NFS, only root can mount, and we can choose to mount NFS servers that we consider to be reasonably reliable. Let's assume that our users have no hostile intentions, but might do stupid things accidentally. Also, I'm not really worried about the contents of the filesystems they might mount, since our users already have shell access and can copy anything they want to their home directory.

  • BYOD (accessing files) on a domain without joining?

    - by Philip White
    I run a Samba 4 instance at a small private school. This makes a regular Linux server appear as a directory controller. There are two relevant benefits to this: I have a Samba share for people's documents, and I use the Redirected Folders feature to allow any employee to sit down at any PC, log in with their domain credentials, and their My Documents points to network storage. Everyone has a mapped drive (using Group Policy Preferences) to a share specific to their account type. Students can access one share (one share for all students), teachers have another, and office staff have another. However, I would like to allow BYOD (Bring Your Own Device). Some employees are already asking for it with their personal laptops, and I know eventually most everyone will want to. Is there any way to replicate the two features above without having to join PCs to the domain? Joining personal PCs is impractical if only because only professional editions of Windows support this. Ideally, any operating system (including mobile) could access the relevant shares, but of course Windows is key. Offline caching is optional. (I could set up OpenVPN for teachers who want to access their files from home.) The problem with simply giving SSH access to the relevant shares is primarily that Samba 4 relies on ext4 ACLs and ext4 extended attributes to maintain NTFS permissions. Writing files directly to the Linux server would bypass this and would (probably) not be interoperable with Samba4. Right now I am completely flexible. I am even fine with scrapping the whole domain and using some other software for the two features above. How can I allow school employees and students freedom to securely share files without requiring everyone to have specific editions of Windows?

  • Unable to get to remote samba share

    - by tubaguy50035
    I have a remote VPS that I would like to setup samba on and only allow my IP access to it. I currently have in my smb.conf: [global] netbios name = apollo security = user encrypt passwords = true socket options = TCP_NODELAY printing = bsd log level = 3 log file = /var/log/samba/log/%m debug timestamp = yes max log size = 100 [hosting] path = /hosting/ comment = Hosting Folder browseable = yes read only = yes guest account = yes valid users = nick I have the ports (137,138,139,445) open in iptables (they're open to everyone right now while I debug) and I see nothing in the syslog about iptables blocking my requests. When I try to open a file browser to my address \\ipaddress, it hangs for a good thirty seconds, and then opens a log in box. I enter my user name and password for the server, hit okay. It then opens the same box, I enter my credentials again and hit enter. Windows then tells me it could not connect. My user account is added to Samba already. Anybody have any suggestions what I can do to get this working?

  • Zero downtime deployment (Tomcat), Nginx or HAProxy, behind hardware LB - how to "starve" old server?

    - by alexeypro
    Currently we have the following setup. Hardware Load Balancer (LB) Box A running Tomcat on 8080 (TA) Box B running Tomcat on 8080 (TB) TA and TB are running behind LB. For now it's pretty complicated and manual job to take Box A or Box B out of LB to do the zero downtime deployment. I am thinking to do something like this: Hardware Load Balancer (LB) Box A running Nginx on 8080 (NA) Box A running Tomcat on 8081 (TA1) Box A running Tomcat on 8082 (TA2) Box B running Nginx on 8080 (NB) Box B running Tomcat on 8081 (TB1) Box B running Tomcat on 8082 (TB2) Basically LB will be directing traffic between NA and NB now. On each of Nginx's we'll have TA1, TA2 and TB1, TB2 configured as upstream servers. Once one of the upstreams's healthcheck page is unresponsive (shutdown) the traffic goes to another one (HttpHealthcheckModule module on Nginx). So the deploy process is simple. Say, TA1 is active with version 0.1 of the app. Healthcheck on TA1 is OK. We start TA2 with Healthcheck on it as ERROR. So Nginx is not talking to it. We deploy app version 0.2 to TA2. Make sure it works. Now, we switch the Healthcheck on TA2 to OK, switch Healthcheck to TA1 to ERROR. Nginx will start serving TA2, and will remove TA1 out of rotation. Done! And now same with the other box. While it sounds all cool and nice, how do we "starve" the Nginx? Say we have pending connections, some users on TA1. If we just turn it off, sessions will break (we have cookie-based sessions). Not good. Any way to starve traffic to one of the upstream servers with Nginx? Thanks!

  • Resize2fs at 81h and counting

    - by Adam
    Setup: 12x 1TB drives in a RAID6 (MDADM) crypt-setup running ontop of MDADM LVM running on the crypted drives EXT4 on the LVM Background: I added a new drive to the RAID (increasing from 11 to 12 drives), and 'bubbled' up through the layers (MDADM, etc...) to reizing the ext4 partition. This machine is used as a centralized repository for photography and as a backup server (for both Windows and Mac machines) so bringing it down to add the drive and wait for the resizing and everything wasn't really an option. So I started the resize operation several days ago. HTOP is reporting the resize2fs operation as running for 81h now. DMESG and syslog are both clear, and the drives are still accessable. The resize command reports it's started an online resize of the partition, so the process IS running, and it is burning through 100% of one of my cores. Question: Is it normal for the operation to take this long or has something gone horribly wrong? Where would I start looking for signs of trouble?

  • Zend Framework 2 loading slow and loss of connection using WAMP

    - by Charlie
    I've been facing an issue with Zend framework running on my local Wamp 2.2 server. I am not sure what I'm doing wrong but ZF2 seems to load really slow when making an http request. Any other request to a php or html file seems to run smoothly. Also, sometimes when the loading time takes longer, I get this message: "The connection to [virtualhostname] was interrupted" I then need to hit refresh to complete the request. I checked apache error log and everything looks fine. Please, I appreciate any type of guide/suggestion to take care of this issue. I followed the starter guide word by word.

  • CentOS - Configuring Puppet to play nice with SELinux

    - by Mike Purcell
    I am running into an issue every time I attempt to start the puppetmasterd service, for which I receive the following error message: root@service1 ~ # -> /etc/init.d/puppetmaster start Starting puppetmaster: Could not prepare for execution: Got 1 failure(s) while initializing: change from absent to directory failed: Could not set 'directory on ensure: Permission denied - /etc/puppet/ssl [FAILED] Apparently there was a known issue with this scenario as outlined in this bug report, however in the bug report it states the issue has been resolved in selinux-policy-3.9.16-29.fc15, but the latest CentOS default upstream version is 3.7.19-155.el6_3.4. So I am trying to figure out the best solution. I can either create a local security policy to allow puppetmasterd the access it needs, or keep researching and install a newer version of selinux-policy outside of the default upstream channel.

  • Is it possible to use WebMatrix with pure IIS?

    - by Mike Christensen
    I'd like to check out WebMatrix for publishing our site to IIS automatically (right now, I have to zip it up, copy it out, Remote Desktop into the server, unzip it, etc). However, every example I can find on how to setup WebMatrix involves Azure, or using a .publishsettings file that you'd get from your hosting provider. I'm curious if I can publish to a normal, every day IIS server running on Windows Server 2008. So far, all I've done to the IIS server is install Web Deploy, which I believe is the protocol that WebMatrix uses to publish. When I enter the Remote Site Settings screen, I select Enter settings. I select Web Deploy as the protocol, type in my NT domain credentials (I'm an Admin on that server). I put in the site URL for the Site Name and Destination URL. When I click Validate Connection, I get: Am I doing something wrong, or is this just not possible to do?

  • How can I replace email alerts for system events with something more scalable?

    - by Dave Forgac
    I have a number of systems and services that send email alerts when some sort of event takes place. This works fine for a small number of systems but as the number of alerts grows the important message become less visible among the informational notices. Email filtering can only be effective to a point. What sort of solution can I use in place of emails that will allow me to send arbitrary alerts from various services and that will scale easily as the number of services grows?

  • Need IP port forwarding to access an internel service running on an internal machine

    - by appleluo
    I am trying to configure iptables to do port forwarding for certain request. The scenario is like this: Login node A can be accessed from outside Compute node B that running the service can be accessed from A but not from outside. I want to set up iptables so that a request for the service on B from outside can be accessed through A. A has two ethernet ports: Internal eth0, with ip internal_A and External eth1, with ip external_A. B has 1 ethernet port, internal eth0. let's say its ip is internal_B The service listens to internal_B:5900. We open external_A:10000 for user access. I configure my iptables with the following commands: echo 1> /proc/sys/net/ipv4/ip_forward /sbin/iptables -P FORWARD ACCEPT /sbin/iptables -t nat -A POSTROUTING -j MASQUERADE /sbin/iptables -A PREROUTING -p tcp -t nat --dport 10000 -j DNAT --to-destination interal_B:5900 /sbin/iptables -A OUTPUT -p tcp -t nat -d external_A --dport 10000 -j DNAT --to-destination internal_B:5900 But it didn't work. Can anybody help me?

  • Redmine on Redhat/CentOS 5 Without using virtual hosts

    - by flyclassic
    I've have followed all the steps to install Redmine on CentOS 5, except for the Apache part: http://www.redmine.org/projects/redmine/wiki/HowTo_install_Redmine_on_CentOS_5 I do not want to configure a virtualhost as we are not using virtual hosts. Can I configure Redmine to run with http://hostname/redmine? Apparently it doesn't work for my case. Redmine was extracted in to the webserver document root /var/www/html/ called /var/www/html/redmine What I did was added a redmine.conf to /etc/httpd/conf.d/ with the following configuration and restarted the server: <Location "/redmine"> Options Indexes ExecCGI FollowSymLinks -MultiViews Order allow,deny Allow from all AllowOverride all PassengerEnabled On RailsBaseURI /var/www/html/redmine RailsEnv production </Location> now i got this error Further information about the error may have been written to the application's log file.

  • How to tell Vim to extend the background color to the whole screen?

    - by chiborg
    I have an issue with the Vim color schemes: The background color does not fill the whole screen. For example, in the "blue" color scheme the whole screen should turn blue. Instead, the blue background only extends to the end of each line. Is this a setting in the console I'm missing or is this an issue with my vim default settings? I'm only having this issue with Ubuntu 10.10. echo $TERM outputs xterm-color. [Update]: To eliminate error sources my minimal ~/.vimrc looks like this: filetype plugin on colorscheme blue syntax on /etc/vim/vimrc contains the unchanged defaults of Ubuntu

  • Windows Server 2008 hangs up while booting

    - by Jim R
    Windows Server 2008 hangs up while booting after Windows update applied several updates. The server is a virtual instance on a Server 2008 Hyper-V host. Other virtual servers are fine, but have not been updated. The normal boot shows the horizontal barber poll forever. When I do a safe boot it also hangs up. With a "Please Wait..." after loading many '.sys' files. The last successfully loaded file listed is: '\Windows\system32\drivers\crcdisk.sys' That is the extent of what I have been able to determine.

  • Can I use a Mac Mini as a web server and database server? What are the pros and cons?

    - by Christopher Altman
    We are a bootstrapped web start up. We have a LAMP web application that we expect relatively low to mid traffic because users need an account to log in. Our current approach is to colocate two servers, a web and mysql database server. We are planning to use Ubuntu Server 9.04. We have shopped around for dedicated servers but the price range from $900 to $1500 per month, therefore we are exploring the colocation approach. We are considering purchasing two Mac Minis (2.0GHz Intel Core 2 Duo 2 Gb RAM) because we are familiar with the machines are the prices are relatively inexpensive. What are the pros and cons of using these 'non-server' grade machines? We would install Ubuntu Sever and attach firewire external hard drives. Any advice on how to set up 'good-and-economic' web/database servers is welcomed.

  • Why does a website server recieve local files much slower than recieve files on other websites?

    - by T...
    The server at http://any2djvu.djvuzone.org receives same files from local computers much slower than from links on other websites (with the same files have been uploaded to the other websites, such as dropbox.com). The speed of uploading a file from local computers to other websites such as dropbox is also much faster than to any2djvu website. For example, a pdf file of 17MB needs more than 1 min to be uploaded to any2djvu server from a local computer with normal ISP such as Comcast High-speed internet, but takes less than 3 seconds from a dropbox link to any2djvu server, and takes around 10 seconds from the same local computer to dropbox. I wonder why there is such big differences for the speeds of different uploading ways to a web server? Thanks!

  • How to make a streaming server to stream media from computer to mobile phone in wifi?

    - by zkz
    Usually we have many HD movies in our computer, but we want to see them by our mobile phone. This requirement produces some questions: 1?the HD videos are too big to transfer to phone timely and it it hard to play on phone smoothly, so we have to transform the videos smaller and fit the screen of phone. 2?the coded format of the videos are varied, but limited types are supported by mobile phone, so we should transform the coded format to those supported by mobile phone. I've leaned the streaming media fit this problem, what I want is: 1?are there any good opensource projects fit this(ffmpeg?live555? darwin?)? 2?are they quick enough to transform coded format and transfer to mobile phone to play with no delay? Thank u very much!

  • How to set Virtualbox appliance as webdev portable sollution?

    - by tenshimsm
    I just want to set a a Virtualbox virtual appliance to make it portable. Meaning that I'll enable a network config which will not need to be changed when I am using my laptop in a different network. I want the virtual machine to have internet access to keep it updated and be able to always have direct access from host using, for example, the IP 10.0.2.100 even when I am in a 192.168.0.1 network. So the first virtual network adapter will have a static ip (10.0.2.100) and the second will receive it from the DHCP. I don't know if 2 virtual adapters are needed or just one to accomplish that.

  • Could I get secure proxy server service free? [closed]

    - by lamwaiman1988
    It comes to my mind that when I use any proxy server, the information will be submit to the proxy server including the username/password of any website I login. This way I risk my identity. I've heard that there are some secure proxy server but can I found any with reasonable price, probably free? ( By the way, VPN is also considered but they are expensive for personal usage ). Even if I can find such service, how can I know that they won't exploit my information?

  • 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.

  • How to back up server with rsync, preserving ownership/permissions without root login

    - by olilarkin
    I am setting up a backup server on which I want to run rsync over ssh to backup content on other servers every night. I would like to set up ssh keys to make it password-less, but I want to preserve ownership of files and permissions. There are a number of users on the server to be backed up which won't all exist on the backup server. What would be the best way to do this? I guess the backup job will need to connect as root to , but I don't want to enable root ssh access on the servers. thanks for any tips, oli ps, all servers are running UBUNTU Server 12.04 LTS and are behind a university firewall.

  • Which Firefox add-on is responsible for a rendering bug?

    - by Gilles
    I've found a page that isn't rendered correctly by Firefox with my usual profile. It is rendered correctly with a blank profile. I have quite a few add-ons. One of them is surely the culprit. How can I find out which? Userscripts often affect the rendering. But I turned off Greasemonkey, and it didn't help. So it's something else, presumably an extension (what else could it be? I have no chrome/userChrome.css.). I'm looking for an easy way to find out which one, easier than disabling a bunch of extensions and restarting umpteen times. Related: Create a tool to help users identify a problematic add-on by bisecting the list of installed add-ons — a similar problem which would admit a similar solution. I want to automate this as much as possible; something like git bisect, that doesn't require me to change my actual profile, would be ideal. A Linux-specific solution is fine with me.

  • Launch Webkit Gtk+ on ubuntu 11.10

    I am using Webkit nightly build revision 110829 on Ubuntu 11.10. I successfully build it. Here is what I did: In the Webkit directory I run: Tools/Scripts/build-webkit --gtk Built succeeded. I tried running it by typing: Tools/Scripts/run-safari --gtk But nothing happens. I mean, the command just did not show anything. Anyone has any idea? For someone who vote down: Like I said, when I run Tools/Scripts/run-safari --gtk nothing happens. So if anyone has any idea how to run it properly please tell me. I followed this instruction: https://trac.webkit.org/wiki/BuildingGtk

  • Scanner Installation: Epson Perfection 3170 Photo, Windows 7 & Adobe Acrobat

    - by Galaxy5727
    I installed the Driver v3.04A from Epson's Web site -- epson12180.exe that is supposedly for Windows 7. Now, the scanner works by itself, i.e. if I hit the scan button I get a dialog menu and can scan with one of the options there but not with Adobe Acrobat. What I need is to have it working from Adobe Acrobat when I go File - Create PDF - From Scanner - Custom Scan... The current state is that I see Scanner: "Please select a device" and no other available devices. I remember I used to see at least 2 other like "WIA Epson Perfection" and smth like "Epson Perfection". "WIA Epson Perfection" is the option that I am hoping to see to move on. Scanner: Epson Perfection 3170 Photo System: Windows 7, 64-bit Software: Adobe Acrobat 9 Pro
