• help with jquery ajax and templates in asp.net mvc

  - by NachoF

  So I have a complex form for an IncomeDeclaration. Its going to display a textfield GrossIncome for each Activity that the IncomeDeclaration is related to... this all gets done on the server and works just fine.... the problem is. The User should also be able to add Activities on the fly.. through javascript... so when the user clicks on Add Activity a Dropdown and a textfield must be appended to the bottom the activities list... heres what Ive got so far <tbody id="activities"> @Html.EditorFor(model => model.income.EconomicActivityIncomeDeclarations) </tbody> </table> <a href="#" id="add_activity">Agregar Otra Actividad</a> </fieldset> <script type="text/javascript"> $("#add_activity").click(function () { $.getJSON('/IncomeDeclarations/GetEconomicActivities', function (data) { var select = new Select(); var data = new Array(); for (var i = 0; i < data.length; i++) { var option = new Option(data[i]["name"], data[i]["i"]) //should do something here } //should call the template and append to #activities }); }); </script> <script id="template" type="text/x-jquery-tmpl"> <tr> <td><select name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].EconomicActivityId"> ${MyOptions} </select></td> <td><input type="text" name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].GrossIncome" /></td>> </tr> </script> } The name attribute for both the select and the text_field is key for this to work... otherwise modelbinding wont work... I would think that if the SomeNumber variable is set to new Date.GetTime() model Binding should work just fine... I actually dont see the need of ajax for this but thats another topic.. I just havent figured out a way to do this without ajax... right now I want to get the template to work and append the form elements to the bottom of the list.

• Alternate way to connect a vpn through a MIFI

  - by questor

  This has gotten to be a major problem at our company and depending on who I ask, the problem either does not really exist (mfr. and vendor) or is insoluble ( according to most users including techs who know how to prove their point). The problem involves getting a normal Windows 7 system to connect to a normal Server 2008 R2 Server over a cellular router (usually called a Mifi). A very few brands/models appear to work but the majority cannot make the connection. Since it is a cellular device, there are many variables that come into play and I wondered if anyone had ever found a consistent way to either make one work or else prove to the providers that their equipment was at fault. They all specifically state “VPN use” on the sales brochures. But few if any work. And those that do are not reliable. From a standpoint of pure knowledge, I just wondered if anyone knew the real reason why they fail? Pptp, L2tp, IPsec doesn’t matter. I have not tried Shrew or OpenVPN and am using strictly MS Windows protocols. Plenty of Google Searches back up my complaints but none seem to be any closer to knowing "why" they fail, just that they do. This is a "quest for knowledge"question. I don't expect a solution. Just a reason for the problem if anyone has any ideas.

• PHP sandbox/sanitize code passed to create_function

  - by kpowerinfinity

  Hello, I am using create_function to run some user-code at server end. I am looking for any of these two: Is there a way to sanitize the code passed to it to prevent something harmful from executing? Alternately, is there a way to specify this code to be run in a sandboxed environment so that the user can't play around with anything else. Thanks!

• System.Timers.Timer/Threading.Timer vs Thread with WhileLoop + Thread.Sleep For Periodic Tasks

  - by Alan

  In my application I have to send periodic heartbeats to a "brother" application. Is this better accomplished with System.Timers.Timer/Threading.Timer or Using a Thread with a while loop and a Thread.Sleep? The heartbeat interval is 1 second. while(!exit) { //do work Thread.Sleep(1000); } or myTimer.Start( () => { //do work }, 1000); //pseudo code (not actual syntax)...

• How does one quickly access ruby and rails documentation when using vim?

  - by 46and2

  Hey all, What method are vim users out there using to quickly access documentation for both ruby and rails (other than switching to the browser to use ruby-doc or railsapi?). I was trying to adapt this script (http://vim.wikia.com/wiki/Online_documentation_for_word_under_cursor) to do the trick however it's only going to work if the cursor is over a class name and I'd like it to work with both class and methods. Thanks.

• iRedMail home setup - use different SMTP relay for different destination domains

  - by John

  Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

• Syncronization between folders MAC OS Lion

  - by Andre Carvalho

  I have an iMac at home and I use a Macbook pro for work. I also have a time capsule at home containing my main folder with my main files. I use it as a NAS besides the Time Machine backup tool. I have several personal files I need to be accessing both at home and at work. My wife, who works at home, uses sometimes the same .XLS files and .DOC files I might have used during my day at work, away from home. My question is: Is there a software, or tool that a I can use to sync my iMac and my MB Pro folders? Remembering that: There might be a chance that my wife and I have changed the same files during the day, so the files would have to be merged so none of the information added by either me or my wife would be lost. The software/tool that would be installed on the MB Pro would need to mount the Time Capsule volume so it could locate the main folder on it. It has to be done automatically when my MB is at home ( with a schedule option ); I have tested some softwares like synctwofolders and Chronosync but none fulfilled all my needs. The first couldn't mount the Time Capsule Volume and didn't have the many schedule options. I really liked Chronosync, but it doesn't merge the files. When it detects a conflict ( for instance: my wife changed a .DOC file on the iMAC and I changed the same file on the MB it asks you to choose which version you want to keep instead of allowing you simply to merge them ). I don't have much experience with automator or scripts but maybe you can give me a hand with that.

• Safari's location bar (auto-suggest and web search)

  - by Lri

  Auto-suggest don't seem to work for queries with spaces. Am I missing something? If you select an item from the suggestion list that was matched by its title, the title is filled in before the address. Can you change it to work like in other browsers? SMRT disables searching by title completely. Can you combine Top Hit, History and Bookmarks into a single section? The preferences starting with DebugSafari4 don't work anymore. (Like DebugSafari4IncludeFancyURLCompletionList.) Can you direct unresolved addresses to something like google.com/search?q=?&btnI instead of ?.com? Like by changing keyword.URL in Firefox. Can you remove or hide the web search field? In Camino, Cruz and Fluid it can be resized to zero width. You can't circumvent the normal maximum ratio with InputFieldWidthRatio. AddressBarIncludesGoogle doesn't appear do anything in the current version. Are there fixes or workarounds to any of these? I'm lumping these issues together, because they are closely related — a lot of them were introduced when the location bar was redesigned in Safari 5. I'm also hoping to find something like an extension or a plugin that would replace the standard location bar.

• How to use MongoRegex (MongoDB C# Driver)

  - by Hery

  Has anyone have any idea how to use MongoRegex for the document search? I attempted this, but returns nothing back: var spec = new Document(); spec.Add("Name", new MongoRegex("/" + searchKey + "*/", "i")); collection.Find(spec) Wondering why it doesn't work, I tried to execute following command from the console: db.things.find({"Name":/john*/i}) /* WORKS */ db.things.find({"Name":"/john*/i"}) /* DOESN'T WORK */ Is that possible that the driver applies double quotation to the regex? Thanks..

• unable to ping hostname, but \\hostname\\c$ works!?

  - by ciscokid

  I'm having a strange issue on my initial lab setup. Situation: Host with OS Server 2008 R2 64bit, on this host a Virtual Machine in Hyper-V with OS Server 2008 SP1 32bit. The virtual machine has a fixed ip, and is referring to itself for the preferred DNS Server (dns server role has been installed). The host has tcp/ip set to automatic (so automatic ip from router, and dns/gateway = router). Both are able to ping each other on IP address (same ip range). Both are NOT able to ping each other on hostname (sounds logic because virtual machine dns server does not yet have a dns record for the hostmachine). But here's the strange thing: I am able to set up a working network mapping on the Virtual Machine to the host: \hostname\c$. The first thing I thougt was 'something' is blocking the ping request, so I completely disabled Windows Firewall on both Virtual Machine and host. Still pinging on hostname in both ways didn't work, yet I am able to access the network mapping on hostname. There is no extra software installed on both systems (clean windows server 2008).Can someone tell me what is causing this? I always thought: ping on IP address works = network mapping on IP address works. Pinging on hostname doesn't work = network mapping on hostname doesn't work neither. Where am I wrong? Looking forward to your advice!

  I have a windows 7 host with firewall turned off. And I have a windowsXP guest running on Virtualbox 4.2.4r81684.

• What are the most common SQL anti-patterns?

  - by le dorfier

  All of us who work with relational databases have learned (or are learning) that SQL is different. Eliciting the desired results, and doing so efficiently, involves a tedious process partly characterized by learning unfamiliar paradigms, and finding out that some of our most familiar programming patterns don't work here. What are the most common antipatterns you've seen (or your self committed), whether generic or product-specific, whether in SQL statements directly, or in the ways applications build and apply them?

• How do I SSH tunnel using PuTTY or SecureCRT through gateway/proxy to development server?

  - by DAE51D

  We have some unix boxes setup in a way that to get to the development box via ssh, you have to ssh into a 'user@jumpoff' box first. There is no direct connection allowed on 'dev' via ssh from anywhere but 'jumpoff'. Furthermore, only key exchange is allowed on both servers. And you always login to the development box as 'build@dev'. It's painful to always do that hopping. I know this can be done with SOCKS or a Tunnel or something... I have setup a FreeBSD VM and I can get things to work awesome using unix ssh tools. Basically all I do is make sure my vm's ~/.ssh/id_rsa.pub key is on both jumpoff and dev and use this ~/.ssh/config file: # Development Server Host ext-dev # this must be a resolvable name for "dev" from Jumpoff Hostname 1.2.3.4 User build IdentityFile ~/.ssh/id_rsa # The Jumpoff Server Host ext Hostname 1.1.1.1 User daevid Port 22 IdentityFile ~/.ssh/id_rsa # This must come below all of the above Host ext-* ProxyCommand ssh ext nc $(echo '%h'|cut -d- -f2-) 22 Then I just simply type "ssh ext-dev" and I'm in like Flynn. The problem is I can't get this same thing to work using either PuTTY or SecureCRT -- and to be honest I've not found any tutorials that really walk me through it. I see many on setting up some kind of proxy tunnel for Firefox, but it doesn't seem to be the same concept. I've been messing with various trial and error most all day and nothing has worked (obviously) and I'm at the end of my ssh knowledge and Google searching. I found this link which seemed to be perfect, but it doesn't work for me. The "Master" connects fine, but the "client" portion doesn't connect. It tells me, the remote system refused the connection. http://www.vandyke.com/support/tips/socksproxy.html I've got the VM, PuTTY and SecureCRT all using the same public/private key pairs to make things consistent and easier to debug. Does anyone have a straight up example of how to do this in Windows?

• Finding Freelance/Contract Coding Projects

  - by Laplie

  What's the best way to find freelance/contract coding projects? I'm looking for paid freelance coding jobs. Almost all of the websites that I've come across are filled with foreigners willing to work at 1/4th the pay, job posters wanting you to recode Microsoft Office for $50, or grey-area coding projects (link generators, bots, trojans). Is there any way to find decent freelance work?

• Using Blowfish Encryption within .NET

  I am working on a project where I need to undertake Blowfish encryption and decryption. Is there anything out there that others are using to do this within but cannot find anything within a .NET C# environment? I would ideally like something does not rely on running an exe as this will eventually live on a live server where exe’s are bared! I have read some of the older posts on SO but nothing suitable. Any ideas? Thanks

• can't Remote desktop to windows XP, blaming the server side

  - by Jin

  After rebooting my work PC (windows XP sp3) this Wednesday (thank to Microsoft Tuesday), I found that I can't remote desktop to my work PC from home (with VPN to company). I have been remote-desktop to work for years and I am really surprised since connectivity is not the problem, so I brought up wireshark to sniff the packets. I can see after TCP handshake, client sent X.224 Connection Request 03 00 00 13 0e e0 00 00 00 00 00 01 00 08 00 03 00 00 00 server sent X.224 Connection Confirm. 03 00 00 0b 06 d0 00 00 12 34 00 According to "MS-RDPBCGR", the official spec on RDP, the server should include Negotiation Response in the "Connection Confirm" message but it didn't. It's empty. I googled a lot but didn't find any clue on why server did that. By the way, I used the same remote desktop client and can connect to other windows XP PC. Here are a couple of pieces of information that may help to give a clue: Since TCP handshake (server port being 3389), I believe the svchost service is actually running. going to control panel -- system window, --- "Remote" tab, the remote desktop is indeeded checked and it states that my username is allowed. according to the packet capture, client didn't even get a chance to tell server what user was trying to logon. Yes, the progress bar showed up a few seconds and then it went back to the "Remote desktop Connection" window again. Searched "windowsupdate.log", didn't find any appearance of the word "remote".

• How to ignore expired certificates from outside a Java application?

  - by Creepy Gnome

  We have a Java application that we need to ignore an expired self-signed cert, however we cannot modify the code to do this. I wondering if there was a System Property or environment variable that we could provide at start up that would allow us to have all expired cert's ignored for now, or even be more specific and provide externally the specific cert that we would like to have the expiration ignored. Anyone have any ideas that would work?

• ssh timeout issue connecting to an EC2 instance on OS X

  - by mamusr

  I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?
