  • How to use visual_effect on DOM after loading the page?

    - by Acidburn2k
    I would like to make one of the div's hidden while rendring. After page is loaded I would like it to appear on the page using virtual_effect. I know how to do it in JS / jQuery. Is that possible with pure Ruby code using Prototype? update_page_tag doesn't really solves the problem It work ok with :highligth, but I can't get it to work with :apper or :slide_down.

  • Do you feel underappreciated or resent the geek/nerd stigma?

    - by dotnetdev
    At work we have a piece of A4 paper with the number of everyone in the office. The structure of this document is laid out in rectangles, by department. I work for the department that does all the technical stuff. That includes support—bear in mind that the support staff isn't educated in IT but just has experience in PC maintenance and providing support to a system we resell but don't have source code access to, project manager, team leader, a network administrator, a product manager, and me, a programmer. Anyway, on this paper, we are labelled as nerds and geeks. I did take a little offence to this, as much as it is light hearted (but annoying and old) humour. I have a vivid image that a geek is someone who doesn't go out but codes all day. I code all day at home and at work (when I have something to code...), but I keep balance by going out. I don't know why it is only people who work with computers that get such a stigma. No other profession really gets the same stigma—skilled, technical, or whatever. An account manager (and this is hardly a skilled job) says, "Perhaps [MY NAME HERE] could write some geeky code tomorrow to add this functionality to the website." It is funny how I get such an unfair stigma but I am so pivotal. In fact, if it wasn't for me, the company would have nothing to sell so the account managers would be redundant! I make systems, they get sold, and this is what pays the wages. It's funny how the account managers get a commission for how many systems they sell, or manage to make clients resubscribe to. Yet I built the thing in the first place! On top of that, my brother says all I do is type stuff on a keyboard all day. Surely if I did, I'd be typing at my normal typing speed of 100wpm+ as if I am writing a blog entry. Instead, I plan as I code along on the fly if commercial pressures and time prohibit proper planning. I never type as if I'm writing normal English. There is more to our jobs than just typing code. And my brother is a pipe fitter with no formal qualifications in his name. I could easily, and perhaps more justifiably, say he just manipulates a spanner or something. Does you feel underappreciated or that a geek/nerd stigma is undeserved or unfair?

  • [C#][WebBrowser] Two Questions

    - by Rudi
    How can I get an HtmlElement if the source code doesn't have the "id=''", but only has the "name=''". Document.GetElementById() doesn't work, and Document.All[""] doesn't work (obviously, because there is no ID. How can I simulate a form post? Question 1 is more important because I found it harder to search. Question 2 I think i can get with more searching.

  • Can't star SSH on Ubuntu 12.10 AWS EC2

    - by Conor H
    So i've just started playing around with Ubuntu on Amazon EC2. I've just issued the following command to restart ssh but it has now "killed" ssh. sudo /etc/init.d/ssh restart I can't seem to ssh to this instance anymore. Putty just gives me "connection refused". NOTE: In this case I just restarted SSH to see the result. I didn't change any settings. This was to confirm that it was the restart command was the problem and not any configs I made. What is the correct way to restart SSH? P.S. That usually works on other Ubuntu boxes. Thanks. EDIT: It is also worth noting that when I ran that command I was taken straight back to a prompt. I didn't get any output on the console.

  • Recovering text files in terminal using grep on Mac OS X Snow Leopard

    - by littlejim84
    I foolishly removed some source code from my Mac OS X Snow Leopard machine with rm -rf when doing something with buildout. I want to try and recover these files again. I haven't touched the system since to try and seek an answer. I found this article and it seems like the grep method is the way to go, but when running it on my machine I'm getting 'Resource busy' when trying to run it on the disk. I'm using this command: sudo grep -a -B1000 -A1000 'video_output' /dev/disk0s2 > file.txt Where 'dev/disk0s2' is what came up when I ran df. I get this when running: grep: /dev/disk0s2: Resource busy I'm not an expert with this stuff, I'm trying my best. Please can anyone help me further? I'm on the verge of losing two days of source code work! Thank you

  • RRAS Problem routing to central site from RRAS server only?

    - by TomTom
    Given is an office connected to headquarters using a RRAS bridge (2 virtual machines using RRAS to route between the two networks). Naming: The office is A, the RRAS on A is a-lnk. THe headquartters is B, b-lnk the RRAS machine there. The VPN works perfectly - machines can ping and work between the sites. Domain controllers on both ends replicating, DFS working, remote desktop working. All in all... everything is fine. EXCEPT: a-lnk itself can not reach any machine in B. This would normally not be troublesome (noone ever does anything on a-lnk), but there are two exceptions: * a-lnk is supposed to get it's license from a KMS in B, so not being able to reach B means it is not prolonging. * a-lnk is supposed to pull updates from a WSUS in B - and not being able to reach B means - no updates. Given that thigns work (and security is a minor issue - A-lnk is not reachable from the internet as it is behing a NAT hardware anyway) this got not handled for months. I just wan to get this item ticked off now. Anyone an idea what this is? It definitely is not a "dns does not work" or "routing in general is bad" item, as any computer in A can connect to any computer in B, and the other way arount - only the RRAS computer itself seems to do something really awkward. Platform for both: 2008 R2 standard.

  • Xorg input devices fail without udev

    - by Sampo
    What I am trying to do: Launch Xorg server without udev device manager. What I have tried to do: Make sure that /dev/ has all required nodes, such as /dev/input/*. Make sure that all required kernel modules are loaded. Launch Xorg. What happens: Xorg starts up as excepted. Xorg loads correct GPU driver and sets right screen resolution. Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1). Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input. Why I think that it should work: Same configuration works well if udev is loaded. Loading udev does not add or modify /dev/ contents, all nodes stays same. My main question is: How to make Xorg input devices work without udev? Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.

  • printf and formatting rules

    - by Stringer Bell
    I'd like to know if all formatting rules of printf functions currently work (or are implemented) in F# ? For instance, if I want to align arguments on 9 characters (padding with spaces or 0), I would use: printfn "%9A %9A" arg1 arg2 //don't seem to work Thanks!

  • Heartbeat won't start up from a cold boot when a failed node is present

    - by Matthew
    I currently have two ubuntu servers running Heartbeat and DRBD. Let's say one node is down... The servers are directory connected with a 1000Mbps cross over cable on eth1 and have access to a IP camera LAN on eth0 The node that is still functioning won't start up heartbeat and provide access to the drbd resource. I have to manually restart heartbeat by "sudo service heartbeat restart" to get everything up and running. How can I get it to start fine from a cold start? Here is the my ha.cf and some material from the syslog... If I'm missing any information that might be of some help. http://pastebin.com/rGvzVSUq <--- Syslog http://pastebin.com/VqpaPSb5 <--- ha.cf

  • with nginx having the base url rewrite to https

    - by jchysk
    I'd like only my base domain www.domain.com to be rewritten to https://www.domain.com By default in my https block I have it reroute to http:// if it's not ~uri = "/" (base domain) or static content. server { listen 443; set $ssltoggle 2; if ($uri ~ ^/(img|js|css|static)/) { set $ssltoggle 1; } if ($uri = '/') { set $ssltoggle 1; } if ($ssltoggle != 1) { rewrite ^(.*)$ http://$server_name$1 permanent; } } So in my http block I need to do the rewrite if it has to https: server { listen 80; if ($uri = '/') { set $ssltoggle 1; } if ($ssltoggle = 1) { rewrite ^(.*)$ https://$server_name$1 permanent; } } If I don't have the $uri = '/' if-statement in the http block, then https works fine if I go directly to it, but I won't get redirected if I go to regular http which is expected. If I do put that in-statement in the http block then everything stops working within minutes. It might work for a few requests, but will always stop within a minute or so. In browsers I just get a blank page for all requests. If I restart nginx it continues to not work until I remove both if-statement blocks in both the https and http blocks and restart nginx. When I look in the error logs I don't see anything logged. When I look in the access log I see this message: "-" 400 0 "-" "-" which I assume means a 400 error. I don't understand why this doesn't work for me. My end goal is to have the base domain be https-only while all other pages default to http. How can I achieve this?

  • Using GQL to check if BlobProperty is NULL

    Hello, I have a db.BlobProperty property (called "Icon") in my entity which contains an image binary. I want to run a GQL query to retrieve all entities with an image (i.e. their "Icon" property is not NULL). Trying to use the following query: "SELECT * FROM Names WHERE Icon!=NULL" did not work... Trying to use .filter("Icon!=",None) did not work as well... Any ideas? Thanks! Joel

  • Difference between tcp recv buffer and tcp receive window size?

    - by pradeepchhetri
    The command shows the tcp receive buffer size in bytes. $ cat /proc/sys/net/ipv4/tcp_rmem 4096 87380 4001344 where the three values signifies the min, default and max values respectively. Then I tried to find the tcp window size using tcpdump command. $ sudo tcpdump -n -i eth0 'tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and port 80 and host google.com' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:15:41.465037 IP 172.16.31.141.51614 > 74.125.236.73.80: Flags [S], seq 3661804272, win 14600, options [mss 1460,sackOK,TS val 4452053 ecr 0,nop,wscale 6], length 0 I got the window size to be 14600 which is 10 times the size of MSS. Can anyone please tell me the relationship between the two.

  • Compiling Ruby on Mac OS X Snow Leopard

    - by gryzzly
    Hi, I am trying to follow this tutorial, on the subject of compiling ruby and rubygems on Snow Leopard: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard I have added this to my ~/.profile: export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" But if I write: echo $PATH I get: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin But in tutorial it says: You should see /usr/local/bin at the beginning of the line returned by the system. I have installed macports sometime ago and plenty of other software, perhaps it has changed the path. Anyway, I have tried to proceed with the installation, so I have built ruby, I did: ./configure --enable-shared --enable-pthread CFLAGS=-D_XOPEN_SOURCE=1 make sudo make install cd .. But when I do which ruby I get: /usr/bin/ruby And according to the tutorial that's wrong. Also if I do ruby -v I get the older version of ruby that was preinstalled on Snow Leopard and not the one I've compiled. Thanks.

  • Removing perl module installed with cpanm

    - by ZeC
    I am Perl beginner. I wanted to use Log::Log4perl module as I am familiar how it works in Java. I used cpanm script to download module, but I ran it without "sudo". Then it installed this module to my dir /home/amer/perl5. Afterwards, I installed it as sudoer, but I want to remove installation in my home dir to avoid any conflicts in future. How can I do that? Here is my cmdline execution stack. Thanks and Regards!

  • NAT vs public IP (and blocked ports)

    - by user1646166
    I have a problem with my ISP. They say that they don't block any ports and I have public IP, while I think these both statements are false. Before I talk to them again (which is really tough when my understanding of these terms is different than theirs) I would like to make some things clear. It seems like my computer is behind NAT (is it possible to have public IP and be behind NAT at the same moment?). When I check my IP, through some external server, and type that IP into browser I get a home page of some router (not mine). Isn't that a proof that my IP isn't public? Also, I have problems with making connections via some ports. E.g. when I'm trying to connect through some high port ( 1023) via SSH, it doesn't work. Is it possible that certain range of outgoing ports from my computer are blocked? Or is it simply because that my ssh client (PuTTY) can't receive incoming packets because of blocked incoming ports? To avoid some questions: it's not a problem with my router, I tried connecting my PC directly and it also didn't work, while having connected by 3G using phone with USB tethering, it does work. Thanks!

  • UFW: force traffic thru OpenVPN tunnel / do not leak any traffic

    - by hotzen
    I have VPN access using OpenVPN and try to create a safe machine that does not leak traffic over non-VPN interfaces. Using the firewall UFW I try to achieve the following: Allow Access from LAN to the machine's web-interface Otherwise only allow Traffic on tun0 (OpenVPN-Tunnel interface when established) Reject (or forward?) any traffic over other interfaces Currently I am using the following rules (sudo ufw status): To Action From -- ------ ---- 192.168.42.11 9999/tcp ALLOW Anywhere # allow web-interface Anywhere on tun0 ALLOW Anywhere # out only thru tun0 Anywhere ALLOW OUT Anywhere on tun0 # in only thru tun0 My problem is that the machine is initially not able to establish the OpenVPN-connection since only tun0 is allowed, which is not yet established (chicken-egg-problem) How do I allow creating the OpenVPN connection and from this point onward force every single packet to go thru the VPN-tunnel?

My boss wants to know how much work is left to do...and I don't know because I haven't planned those iterations. Can anyone give me advice or a resource to reference on what I need to do in order to provide him with what he needs?
