  • Letting users trial your web app before sign-up: sessions or temp db?

    - by Mat
    I've seen a few instances now where web applications are letting try them out without you having to sign-up (though to save you need to of course). example: trial at http://minutedock.com/ I'm wondering about doing this for my own web app and the fundamental question is whether to store their info into sessions or into a temp user table? The temp user table would allow logging and potentially be less of a hit on the server correct? Is there a best practice here?

  • Can't sign into linkedin when using a QT4 (WebKit-based) browser?

    - by Inshim
    I started using the lightweight QT4 browser for some of the time on my Mac. Most simple websites, and even quite a few AJAX-heavy web apps, work for me flawlessly, including gmail (!) However, with LinkedIn, I can't even manage to sign in. Even when I change the useragent to one of a regular browser, it keeps kicking me out. Any ideas what could be wrong and for some workaround? Thanks!

  • Django - urls.py - Filenames with a hash/pound (#) sign?

    - by miya
    I'm using django and realized that when the filename that the user wants to access (let's say a photo) has the pound sign, the entry in the url.py does not match. Any ideas? url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': MEDIA_ROOT}, it just says: "/home/user/project/static/upload/images/hello" does not exist when actually the name of the file is: hello#world.jpg Thanks, Nico

  • Adding negative and positive numbers in java without BigInt.

    - by liamg
    Hi, i'm trying to write a small java class. I have an object called BigNumber. I wrote method that add two positive numbers, and other method that subract two also positive numbers. Now i want them to handle negative numbers. So the i wrote couple of 'if' statements eg. if (this.sign == 1 /* means '+' */) { if (sn1.sign == 1) { if (this.compare(sn1) == -1 /* means this < sn1 */ ) return sn1.add(this); else return this.add(sn1); } etc. Unfortunately the code looks just ugly. Like a bush of if's and elses. Is there a better way to write that kind of code? Edit i can't just do this.add(sn1) beacuse sometimes i want to add positive number to negative one or negitve to negative. But add can handle only positive numbers. So i have to use basic math and for example: instead of add negative number to negative number i add this.abs() (absolute value of number) to sn1.abs() and return the result with opposite sign. Drew: this lines are from method _add. I use this method to decide what to do with numbers it receive. Send them to add method? Or send them to subract method but with different order (sn1.subtract(this))? And so on.. if (this.sign == 1) { if (sn1.sign == 1) { if (this.compare(sn1) == -1) return sn1.add(this); else return this.add(sn1); } else if (wl1.sign == 0) return this; else { if (this.compare(sn1.abs()) == 1) return this.subtract(sn1.abs()); else if (this.compare(sn1.abs()) == 0) return new BigNumber(0); else return sn1.abs().subtract(this).negate(); // return the number with opposite sign; } } else if (this.sign == 0) return sn1; else { if (wl1.sign == 1) { if (this.abs().compare(sn1) == -1) return sn1.subtract(this.abs()); else if (this.abs().compare(sn1) == 0) return new BigNumber(0); else return this.abs().subtract(sn1).negate(); } else if (sn1.sign == 0) return this; else return (this.abs().add(wl1.abs())).negate(); } As you can see - this code looks horrible..

  • Raspberry Pi entrance signed backed by Umbraco - Part 1

    - by Chris Houston
    Being experts on all things Umbraco, we jumped at the chance to help our client, QV Offices, with their pressing signage predicament. They needed to display a sign in the entrance to their building and approached us for our advice. Of course it had to be electronic: displaying multiple names of their serviced office clients, meeting room bookings and on-the-pulse promotions. But with a winding Victorian staircase and minimal storage space how could the monitor be run, updated and managed? That’s where we came in…Raspberry PiUmbraco CMSAutomatic updatesAutomated monitor of the signPower saving when the screen is not in useMounting the screenThe screen that has been used is a standard LED low energy Full HD screen and has been mounted on the wall using it's VESA mounting points, as the wall is a stud wall we were able to add an access panel behind the screen to feed through the mains, HDMI and sensor cables.The Raspberry Pi is then tucked away out of sight in the main electrical cupboard which just happens to be next to the sign, we had an electrician add a power point inside this cupboard to allow us to power the screen and the Raspberry Pi.Designing the interface and editing the contentAlthough a room sign was the initial requirement from QV Offices, their medium term goal has always been to add online meeting booking to their website and hence we suggested adding information about the current and next day's meetings to the sign that would be pulled directly from their online booking system.We produced the design and built the web page to fit exactly on a 1920 x 1080 screen (Full HD in Portrait)As you would expect all the information can be edited via an Umbraco CMS, they are able to add floors, rooms, clients and virtual clients as well as add meeting bookings to their meeting diary.How we configured the Raspberry PiAfter receiving a new Raspberry Pi we downloaded the latest release of Raspbian operating system and followed the official guide which shows how to copy the OS onto an SD card from a Mac, we then followed the majority of steps on this useful guide: 10 Things to Do After Buying a Raspberry Pi.Installing ChromiumWe chose to use the Chromium web browser which for those who do not know is the open sourced version of Google Chrome. You can install this from the terminal with the following command:sudo apt-get install chromium-browserInstalling UnclutterWe found this little application which automatically hides the mouse pointer, it is used in the script below and is installed using the following command:sudo apt-get install unclutterAuto start Chromium and disabling the screen saver, power saving and mouseWhen the Raspberry Pi has been installed it will not have a keyboard or mouse and hence if their was a power cut we needed it to always boot and re-loaded Chromium with the correct URL.Our preferred command line text editor is Nano and I have assumed you know how to use this editor or will be able to work it out pretty quickly.So using the following command:sudo nano /etc/xdg/lxsession/LXDE/autostartWe then changed the autostart file content to:@lxpanel --profile LXDE@pcmanfm --desktop --profile LXDE@xscreensaver -no-splash@xset s off@xset -dpms@xset s noblank@chromium --kiosk --incognito http://www.qvoffices.com/someURL@unclutter -idle 0The first few commands turn off the screen saver and power saving, we then open Cromium in Kiosk Mode (full screen with no menu etc) and pass in the URL to use (I have changed the URL in this example) We found a useful blog post with the Cromium command line switches.Finally we also open an application called Unclutter which auto hides the mouse after 0 seconds, so you will never see a mouse on the sign.We also had to edit the following file:sudo nano /etc/lightdm/lightdm.confAnd added the following line under the [SeatDefault] section:xserver-command=X -s 0 dpmsRefreshing the screenWe decided to try and add a scheduled task that would trigger Chromium to reload the page, at some point in the future we might well change this to using Javascript to update the content, but for now this works fine.First we installed the XDOTool which enables you to script Keyboard commands:sudo apt-get install xdotoolWe used the Refreshing Chromium Browser by Shell Script post as a reference and created the following shell script (which we called refreshing.sh):export DISPLAY=":0"WID=$(xdotool search --onlyvisible --class chromium|head -1)xdotool windowactivate ${WID}xdotool key ctrl+F5This selects the correct display and then sends a CTRL + F5 to refresh Chromium.You will need to give this file execute permissions:chmod a=rwx refreshing.shNow we have the script file setup we just need to schedule it to call this script periodically which is done by using Crontab, to edit this you use the following command:crontab -eAnd we added the following:*/5 * * * * DISPLAY=":.0" /home/pi/scripts/refreshing.sh >/home/pi/cronlog.log 2>&1This calls our script every 5 minutes to refresh the display and it logs any errors to the cronlog.log file.SummaryQV Offices now have a richer and more manageable booking system than they did before we started, and a great new sign to boot.How could we make sure that the sign was running smoothly downstairs in a busy office centre? A second post will follow outlining exactly how Vizioz enabled QV Offices to monitor their sign simply and remotely, from the comfort of their desks.

  • How to use Windows login for single-sign-on and for Active Directory entries for Desktop Java applic

    - by Touko
    I'd like to have my desktop Java application to have single sign on related to Active Directory users. In two steps, I'd like to : Be sure that the particular user has logged in to Windows with some user entry. Check out some setup information for that user from the Active Directory With http://stackoverflow.com/questions/31394/java-programatic-way-to-determine-current-windows-user I can get the name of the current Windows user but can I rely to that? I think the System.getProperty("user.name") won't be secure enough? ("user.name" seems to be got from environment variables, so I can't rely on that, I think?) Question http://stackoverflow.com/questions/390150/authenticating-against-active-directory-with-java-on-linux provides me the authentication for given name+pass but I'd like to authenticate based on the Windows logon? For the Active Directory access, the LDAP would probably be the choise? I'm not totally sure if I'm asking the right questions but hopefully somebody has some ideas to forward me on.

  • How can I sign an ActiveX control with a code signing certificate and be a verified publisher?

    - by davidcl
    I'm trying to sing an ActiveX control with a code signing certificate issued by Thawte. I was able to successfully sign the control using signtool.exe. When I look at the file properties, it says "The certificate in the signature cannot be verified." When I view the certificate it says "Windows does not have enough information to verify the certificate." On the certification path tab, it says "The issuer of this certificate cannot be found." In internet explorer, the certificate is recognized as signed but the user receives warnings that the publisher is not verified. I've tried creating a single PFX file containing my certificate along with the root and intermediate certificates that chain to my Thawte developer certificate, and then re-signing the control using that PFX file. No dice. Any suggestions?

  • Is there an easy way to sign a C++ CLI assembly in VS 2010?

    - by jyoung
    Right now I am setting the Linker/Advanced/KeyFile option. I am getting the "mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.". Reading from the web, it sounds like I have to set the delay signing option, download the SDK, and run sn.exe as a post build event. Surely there must be an easier way to do this common operation in VS2010?

  • How do I sign a HTTP request with a X.509 certificate in Java?

    - by Rune
    How do I perform an HTTP request and sign it with a X.509 certificate using Java? I usually program in C#. Now, what I would like to do is something similar to the following, only in Java: private HttpWebRequest CreateRequest(Uri uri, X509Certificate2 cert) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri); request.ClientCertificates.Add(cert); /* ... */ return request; } In Java I have created a java.security.cert.X509Certificate instance but I cannot figure out how to associate it to a HTTP request. I can create a HTTP request using a java.net.URL instance, but I don't seem to be able to associate my certificate with that instance (and I'm not sure whether using java.net.URL is even appropriate).

  • How do I digitally sign an HTTPS request in .net?

    - by Endy Tjahjono
    Is there a built in procedure to digitally sign an HTTPS request with client's SSL private key in .net? Also, is there a built in procedure to verify the digital signature against an SSL certificate? Or do I have to roll my own? Or is there a third party library? I need the request to be digitally signed because the client manipulates money, so I want to be sure that the request really comes from the client and that nobody tampers with the content of the request. I'm also considering using SSL client certificate, but it can only provide confidentiality and authentication, but not data integrity.

  • Facebook page linking to external site sign-up process, capture permission to write to wall in process?

    - by steve
    Hi all, Have had a good hunt through the archive but can't find anyone trying to do this... hope someone familiar with the facebook API can confirm if it's possible? Basically I have a client who wants to replicate their membership sign up process in a tab on their facebook page. The form would still submit to their own website to process, we'd just be replicating the form fields. As an additional requirement they want to capture peoples facebook user ID and get permission to post back to a users wall at the same time... The idea being that once the user is a member we can post back to their wall so their friends see that they've signed up... Basically after a sanity check that: 1) these things are possible to do; 2) the best method to build the form in a FB page - I'm guessing using JS to create all fields & ajax to submit to the external site? Thanks Steve

  • how to turn off percentage sign in .net/wpf?

    - by Vitalik
    I would like my WPF application to display all percentages without % sign. For example 20% would be displayed as "20" but i still want to use the standard formatting for percentages (so i get the benefit of string formatter to multiply it by 100 for me) in other words, how do i get string.Format("0.00%", 0.2) to output "20" but not "20%"? Is it possible to globally define PercentSymbol as empty string for the entire application? In particular i am using ContentStringFormat in my WPF application to format the numbers and percentages. Maybe i can do it directly in WPF.

  • How do I specify the regular expression to disable the use of underscores after the '@' sign in php for email validation?

  • Single Sign On for WebServices, WCS, WFS, WMS (Geoserver), etc.

    - by lajuette
    I'm trying to implement a Single Sign On (SSO) for a web application. Maybe you can help me find a proper solution, give me a direction or tell me, that solutions already exist. The scenario: A GeoExt (ExtJS for geodata/map based apps) webapp (JavaScript only) has a login form to let the user authenticate himself. The authentication is not implemented yet, so i'm flexible with respect to that. After authenticating to the main webapp the user indirectly accesses multiple 3rd-party services like WebServices, GeoServer WFS, Google Maps, etc. These services might require additional authentication like credentials or keys. We are (so far) not talking about additional login screens, just some kind of "machine to machine"-authentication. The main problem: I'm unable to modify the 3rd party services (e.g. Google) to add a SSO mechanism. I'd like to have a solution that allows the user to log in once to have access to all the services required. My first idea was a repository that stores all the required credentials or keys. The user logs in and can retrieve all required information to acces sthe other services. Does anybody know of existing implementations, papers, maybe implementations of such services? Other requirements: The communication between the JS application and the repository must be secure. The credentials must be stored in a secure manner. But the JS app must be able to use them to access the services (no chance to store a decryption key in a JS-app securely, eh? *g).

  • How do I sign requests reliably for the Last.fm api in C#?

    - by Arda Xi
    I'm trying to implement authorization through Last.fm. I'm submitting my arguments as a Dictionary to make the signing easier. This is the code I'm using to sign my calls: public static string SignCall(Dictionary<string, string> args) { IOrderedEnumerable<KeyValuePair<string, string>> sortedArgs = args.OrderBy(arg => arg.Key); string signature = sortedArgs.Select(pair => pair.Key + pair.Value). Aggregate((first, second) => first + second); return MD5(signature + SecretKey); } I've checked the output in the debugger, it's exactly how it should be, however, I'm still getting WebExceptions every time I try. Here's my code I use to generate the URL in case it'll help: public static string GetSignedURI(Dictionary<string, string> args, bool get) { var stringBuilder = new StringBuilder(); if (get) stringBuilder.Append("http://ws.audioscrobbler.com/2.0/?"); foreach (var kvp in args) stringBuilder.AppendFormat("{0}={1}&", kvp.Key, kvp.Value); stringBuilder.Append("api_sig="+SignCall(args)); return stringBuilder.ToString(); } And sample usage to get a SessionKey: var args = new Dictionary<string, string> { {"method", "auth.getSession"}, {"api_key", ApiKey}, {"token", token} }; string url = GetSignedURI(args, true); EDIT: Oh, and the code references an MD5 function implemented like this: public static string MD5(string toHash) { byte[] textBytes = Encoding.UTF8.GetBytes(toHash); var cryptHandler = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] hash = cryptHandler.ComputeHash(textBytes); return hash.Aggregate("", (current, a) => current + a.ToString("x2")); }

  • How can I sign a Windows Mobile application for internal use?

    - by AR
    I'm developing a Windows Mobile application for internal company use, using the Windows Mobile 6 Professional SDK. Same old story: I've developed and tested on the emulator and all is well, but as soon as I deploy to advice I get an UnauthorizedAccessException when writing files or creating directories. I'm aware that an application installed to a device needs to be signed but I'm running into roadblocks at every turn: Using the project properties 'Devices' window I select 'Sign the project output with this certificate, and choose one of the sample certificates from the SDK. This results in a build error: "The signer's certificate is not valid for signing" when running SignTool. If I try to run SignTool.exe from the commandline, I get an error telling me to run SignTool.exe from a location in the system's PATH. I can't use the 'Signing' tab in the Project Properties to create a test certificate - this is greyed out (presumably for WinMobile projects?). If at all possible, I would like to avoid having to go through Versign or the like to get a Mobile2Market certificate. If I have to go this route for a final version that's fine, but I need to at least be able to test the app on real devices. Any advice would be most welcome!

  • JavaScript Keycode 46 is DEL Function key or (.) period sign?

    - by Omar
    Im writing some logic in JavaScript using jquery, where i must check the input content against a REGEX pattern ex: "^[a-zA-Z0-9_]*$" //Alpha-numeric and _ The logic is almost done, i just have a little problem filtering the function key DEL, my logic goes like this: var FunctionsKey = new Array(8, 9, 13, 16, 35, 36, 37, 39, 46); function keypressValidation(key) { if (config.regexExp != null) { if ($.inArray(key, FunctionsKey) != -1) { return true; } else { var keyChar = String.fromCharCode(key); return RegexCheck(keyChar); } } return true; } If the KeyCode is one of those in the array, i let it pass, if not i get the char and compare it against the REGEX. The problem is: in some Browsers the DEL and '.' (period sign) have the same key Code 46. So is there a better logic to filter the function keys or must i write a condition for that case, maybe removing the 46 from the array and try to convert it to char and if is (.) let it go to the Regex function if not let it pass? The other question will be are there more shared Key Codes in some browsers? EDIT: My suggested solution wont work because it doesn't matter which key the user pressed (DEL or period) i always get (.) as CHAR at least on OPERA and FF =(.
