  • Calculating probability that a string has been randomized? - Python

    - by RadiantHex
    Hi folks, this is correlated to a question I asked earlier (question) I have a list of manually created strings such as: lucy87 gordan_king fancy_unicorn77 joplucky_kanga90 base_belong_to_narwhals and a list of randomized strings: johnkdf pancake90kgjd fancy_jagookfk manhattanljg What gives away that the last set of strings are randomized is that sequences such as 'kjg', 'jgf', 'lkd', ... . Any clever way I could separate strings that contain these apparently randomized strings from the crowd? I guess that this plays a lot on the fact that certain characters are more likely to be placed next to others (e.g. 'co', 'ka', 'ja', ...). Any ideas on this one? Kylotan mentioned Reverend, but I am not sure if it can be used fr such purpose. Help would be much appreciated!

  • check external website registration

    - by Arsenal
    Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

  • What mail storage should I choose for our web application; IMAP, key-valud store, rdbms, ...

    - by tvrtko
    I have to store e-mail messages for use with our application. I have "metadata" for all messages inside a relational database, but I don't feel comfortable keeping message content (gigabytes and terabytes of email data) inside a database. I'm currently using IMAP as a storage, but I have my doubts if I choose correctly. First of all there is a problem of uidvalidity and how to keep a permanent reference to message inside IMAP. Second, I'm not sure if this is the most robust solution in terms of backup/restore strategies, corruption of store, replication ... Positive side is that I can query IMAP using the headers because the data is mostly indexed. I don't know if key-value stores are a better approach (Casandra, Tokyo cabinet, redis). How they handle storing 1KB and 50MB of data. How they prevent corruption and when corruption or device failure happens how can I repair the store.

  • How can I stop cruise control re-building after a failed build?

    - by RodeoClown
    I got back from the weekend to discover that somebody *ahem* had missed a file commit last thing Friday afternoon... Cruise control has been having fun, and tried to re-build every five minutes since then despite no further commits. This means that my colleagues and I have received approximately six hojillion emails from cruise control. A single fail email would be more than enough to notify us. Is there any way to stop cruise control building on failure, at least until a new commit occurs?

  • Attack from anonymous proxy

    - by mmgn
    We got attacked by some very-bored teenagers registering in our forums and posting very explicit material using anonymous proxy websites, like http://proxify.com/ Is there a way to check the registration IP against a black list database? Has anyone experienced this and had success?

  • Outgoing Emails (Git Patches) Blocked by Windows Live

    - by SteveStifler
    Just recently I dove into the VideoLAN open source project. This was my first time using git, and when sending in my first patch (using git send-email --to [email protected] patches), I was sent the following message from my computer's local mail in the terminal (I'm on OSX 10.6 by the way): Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. http:/www.spamhaus.org maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support They must think I'm a spammer. I have a dynamic IP and my ISP (Charter) won't let me get a static one, so I tried editing git preferences: git config --global user.email "[email protected]" to my gmail account. However I got the exact same message again. My guess is that it has something to do with the native mail's preferences, but I have no idea how to access them or modify them. Anybody have any ideas for solving this? Thanks!

  • Quick and easy flood protection?

    - by James P
    I have a site where a user submits a message using AJAX to a file called like.php. In this file the users message is submitted to a database and it then sends a link back to the user. In my Javascript code I disabled the text box the user types into when they submit the AJAX request. The only problem is, a malicious user can just constantly send POST requests to like.php and flood my database. So I would like to implement simple flood protection. I don't really want the hassle of another database table logging users IPs and such... as if they are flooding my site there will be a lot of database read/writes slowing it down. I thought about using sessions, like have a session that contains a timestamp that gets checked every time they send data to like.php, and if the current time is before the timestamp let them add data to the database, otherwise send out an error and block them. If they are allowed to enter something into the database, update their session with a new timestamp. What do you think? Would this be the best way to go about it or are there easier alternatives? Thanks for any help. :)

  • What is the best way to avoid SpamCop trigger a ASP.NET web page?

    - by ncakmak
    Good Days, I have recently developed a web application in ASP.NET for a marketer that he has been sending emails to his potential customers to fill out a web form existing in this ASP.NET application. Recently, he received an email from his hosting company saying that they will suspend his account because his emails were triggered by SpamCop. He basically put a link to that web form in the email messages. What would be the best way to handle this situation? Is there a way to avoid this? Thanks, Niyazi

  • Imposing email limits on web page

    - by Martin
    To avoid spammers, what's a good strategy for imposing limits on users when sending email from our site? A count limit per day on individual IPs? Sender emails? Domains? In general terms, but recommended figures will also be helpful. Our users can send emails through our web page. They can register and log in but are also allowed to do this without logging in, but with a captcha and with a field for the senders email. Certainly, there is a header, "The user has sent you the following message.", limiting the use for spammers, so perhaps it's not a big problem. Any comments on what I'm doing will be greatly appreciated.

  • Microsoft pourrait être à l'origine de l'arrêt du Botnet « Rustock », le plus prolifique de l'histoire du spam

    Microsoft pourrait être à l'origine de l'arrêt du Botnet « Rustock » Le plus prolifique de l'histoire du spam Un groupe anonyme d'experts en sécurité a réussi à paralyser les opérations de spams produites depuis des années par Rustock, le plus prolifique Botnet de l'histoire de l'Internet. Depuis l'après-midi du 16, aucun des serveurs de contrôle et commande (CnC) de Rustock ne répond plus. Un exploit qui concorde avec une baisse drastique du nombre de pourriels à l'échelle mondiale. [IMG]http://idelways.developpez.com/news/images/rustock.png[/IMG] Bien que cette opération n'ait pas encore été revendiquée officiellement, une enquête du Wall St...

  • Google pénalise le référencement des sites truffés de publicités, compliquant l'accès au contenu, ils sont considérés comme du spam

    Google pénalise le référencement des sites truffés de publicités Compliquant l'accès au contenu, ils sont considérés comme du spam Matt Cutts, responsable de l'équipe antispam de Google, s'est présenté à la conférence PubCon avec de bonnes et de mauvaises nouvelles. Le moteur de recherche pénalise désormais le référencement des sites truffés de publicités rendant difficile l'accès aux contenus pertinents des pages. Ce qui compte, a expliqué Cutts dans sa keynote est « combien de contenu est au-dessus de la ligne de flottaison [...] Si vous avez des publicités obscurcissant votre contenu, vous avez intérêt à y repenser », laissant entendre que les sites compli...

  • Does Exchange support plussed users (e.g. [email protected]) or a similar mechanism?

    - by Jens Bannmann
    Sendmail supports a feature called 'plussed users'. Once enabled, emails sent to [email protected], [email protected] and [email protected] are automatically delivered just like mails to [email protected]. There is no need to register or set up these 'plus suffixes'. The user can just use them and set up client-side filtering rules on his own. Does Exchange support a similar mechanism? If so, how to enable it? Note that I don't want answers about other means of filtering, e.g. spam/junk filtering, server-side or client-side rules, email aliases/addresses that are configured explicitly and so on.
