• Maximizing TCP connections on HAProxy load balancer

  - by imaginative

  I am currently using HAProxy in order to load balance tcp connections from clients to my Erlang app server. The connection is persistent, which means I'm limited to roughly 64K clients on an optimized server (I'm currently running HAProxy on an m1.large EC2 instance). My app server is designed to horizontally scale based on the number of TCP connections. What's worrying me though is I'll need an equal number of HAProxy servers as app servers since it's a 1:1 connection. Is there currently a way to "proxy" the tcp connection to the app server so that once HAProxy sends the client off to my Erlang server, it can free up the connection, ready to serve another client? Are there any papers, existing solutions out there I can read so that I only have to worry about the 64K limit on my app servers, and not on the load balancing servers themselves?

• What makes signed integers behave differently?

  - by 000

  In this example of x86_64 hex/disassembled code I see: 48B80000000000000000 mov rax, 0x0 Signed Byte 52 Unsigned Byte 52 Signed Short 14388 Unsigned Short 14388 Signed Int 943863860 Unsigned Int 943863860 Signed Int64 3472328296363079732 Unsigned Int64 3472328296363079732 Float 4.630555e-05 Double 1.39804332763832e-76 String 48B80000000000000000 which to me appears to have the same functionality as: 48C7C000000000 mov rax, 0x0 48C7C000000000 Signed Byte 52 Unsigned Byte 52 Signed Short 14388 Unsigned Short 14388 Signed Int 927152180 Unsigned Int 927152180 Signed Int64 3472328377950746676 Unsigned Int64 3472328377950746676 Float 1.163599e-05 Double 1.39806836023098e-76 String 48C7C000000000 How is the first example treated differently from the second example?

• IIS Seems to Forward Domain/IP to Domain Controller

  - by asinc

  We have a server (Server 1) with Win 2008 that is accessible by RDP and also is set as the primary DNS IP for a domain (example.com). This server is on the same network as an SBS 2008 server (Server 2) which is the domain controller and internal Dns server. Web requests going to example.com with IP of Server 1 are being passed to Server 2 and served up by IIS from Server 2. What causes this to happen? Is there a safe way to have Server 1 IIS handle the web requests which was our expected outcome? Example: DNS entry on ISP: example.com = 111.111.111.111 Server 1 = 111.111.111.111 Server 2 = 111.111.111.112 Web user goes to example.com in browser, and the page is actually returned from 111.111.111.112?

• Send as another user / email address in Exchange 2010

  - by adamo

  In my setup there exist user1, ..., [email protected]. Mail for example.com is handled by Exchange 2010 and all the users user Outlook 2010. There also exists a Standard Distribution list named [email protected]. Is it possible to have some of the users being able to send email with [email protected] as the sender address? Can the sender's GECOS be different too when this happens so that the recipient sees "Offices of Example.com" instead of "User Name X"? Sometimes the secretaries need to send stuff as "the office" and not as theirselves ...

• Redirect with .htacess - URL with regex to URL

  - by nicorellius

  I have a temporary need to redirect some installer files on my web site. The redirects that are working now look something like this: Redirect 301 /installer_1.0.0.zip http://www.example.com/download/installer_1.0.3.zip Redirect 301 /installer_1.0.1.zip http://www.example.com/download/installer_1.0.3.zip Redirect 301 /installer_1.0.2.zip http://www.example.com/download/installer_1.0.3.zip I would like to use a regex instead of having multiple lines for each version I need to redirect. I have tried these options with no success: Redirect 301 /installer_(.*).zip http://www.example.com/download/installer_1.0.3.zip Redirect 301 /installer_([0-9+]\.[0-9+]\.[0-9+]).zip http://www.example.com/download/installer_1.0.3.zip Should these work or am I doing something wrong? Thanks.

• AngularJS: structuring a web application with multiple ng-apps

  - by mg1075

  The blogosphere has a number of articles on the topic of AngularJS app structuring guidelines such as these (and others): http://www.johnpapa.net/angular-app-structuring-guidelines/ http://codingsmackdown.tv/blog/2013/04/19/angularjs-modules-for-great-justice/ http://danorlando.com/angularjs-architecture-understanding-modules/ http://henriquat.re/modularizing-angularjs/modularizing-angular-applications/modularizing-angular-applications.html However, one scenario I have yet to come across for guidelines and best practices is the case where you have a large web application containing multiple "mini-spa" apps, and the mini-spa apps all share a certain amount of code. I am not referring to the case of trying to have multiple ng-app declarations on the same page; rather, I mean different sections of a large site that have their own, unique ng-app declaration. As Scott Allen writes in his OdeToCode blog: One scenario I haven't found addressed very well is the scenario where multiple apps exist in the same greater web application and require some shared code on the client. Are there any recommended approaches to take, pitfalls to avoid, or good sample structures of this scenario that you can point to?

• Farmyard

  - by Richard Jones

  Moooooooo     For a while now we’ve been using Apple’s enterprise device app distribution mechanism.   This allows you to have a user, click on a URL on their iOS device and it pulls down a new version of an enterprise app. of of our servers. Its really nice,  have a look at - http://developer.apple.com/library/ios/#featuredarticles/FA_Wireless_Enterprise_App_Distribution/Introduction/Introduction.html   I’ve embedded this, into a check on application launch, that a web-service is called to detect a newer version of the software is available.  It then calls the URL to the App and a new version is deployed. You can alert users that a new App update is available by sending them a push notification.  See screenshot at the top. We send our push notifications out to users,  using a simple C# service.    The fun part is this.   You can instruct the push notification to play a sound (embedded in the app already). So our push notification’s play a random farmyard noise, i.e from a selection of - cow.wav dogbrk.wav duck.wav goose.wav horse.wav lamb.wav monkey.wav – left field I know rooster.wav Imagine my amusement being able to periodically send out an update and watch our office (of about 60 people) turn into farm for a few seconds. I’ve messed up a few times, with people being interrupted on customer conference calls,  but people seem good humoured about it. (so far) Simple(ish) pleasures…

• Can I release complementary Windows 8 and WP8 apps on their respective stores?

  - by Clay Shannon

  I am creating a pair of apps, one to run preferably on tablets, but also laptops and PCs, and the other for WP8. These apps are complementary - having one is of no use without the other. I know there is a Windows Store, and a Windows Phone store, so one would be released on one, and one on the other. My question is: as these apps are useless by themselves (although in most cases it won't be the same people running both apps), will there be a problem with offering these useless-when-used-alone apps? IOW: Person A will use the Windows 8 app to interact with some people that have the WP8 app installed; those with the WP8 app will interact with a person or people who have the Windows 8 app installed. What I'm worried about is if these apps go through a certification process where they must be useful "standalone" - is that the case?

• Why UFW has to be (re)started at boot time if it's only iptables rule manager?

  - by Tomasz Zielinski

  README from source package says: When installing ufw from source, you will also need to integrate it into your boot process for the firewall to start when you restart your system. Depending on your needs, this can be as simple as adding the following to a startup script (eg rc.local for systems that use it): # /lib/ufw/ufw-init start For systems that use SysV initscripts, an example script is provided in doc/initscript.example. See doc/upstart.example for an Upstart example. Consult your distribution's documentation for the proper way to modify your boot process. On my system I have this: # /etc/ufw/ufw.conf # # Set to yes to start on boot. If setting this remotely, be sure to add a rule # to allow your remote connection before starting ufw. Eg: 'ufw allow 22/tcp' ENABLED=yes So, why does simple iptables rule manager need to be started at boot time? Is there any secret to that, or it merely checks if all rules are in place ?

• Sending mail to local address crashes web server (sendmail)

  - by deceze

  When trying to send mail automatically from a script at example.com via PHP's mail() to [email protected], the Apache server throws an Internal Error. I believe internally it is configured to use sendmail. The message gets dropped into ~/dead.letter and the general error log reads: [Wed May 12 11:26:45 2010] [error] [client xxx.xxx.xxx.xxx] malformed header from script. Bad header=/home/example/dead.letter... S: /home/example/www/test.php Trying any other address, not @example.com, works just fine. I have googled and serverfaulted for solutions, but they all require to edit configuration files in /etc/mail and similar system places, which is not an option, since this problem occurs on a shared host in which I only have access to ~/. Does anyone have a suggestion?

• SEO for replacing blog content, but keeping the same page URL

  - by cphill

  This might not have any major impact on the SEO, but basically I have random blog at this URL: http://example.com/blog (not a real URL), that I am removing and replacing with a company blog. I want to use the http://example.com/blog URL address, but I'm not sure how this would effect my SEO since this random blog content that I am removing has the example.com/blog URL prefix. Would I just add a 310 redirect for those old blog articles and leave the basic /blog URL without any redirects?

• Discuss: PLs are characterised by which (iso)morphisms are implemented

  - by Yttrill

  I am interested to hear discussion of the proposition summarised in the title. As we know programming language constructions admit a vast number of isomorphisms. In some languages in some places in the translation process some of these isomorphisms are implemented, whilst others require code to be written to implement them. For example, in my language Felix, the isomorphism between a type T and a tuple of one element of type T is implemented, meaning the two types are indistinguishable (identical). Similarly, a tuple of N values of the same type is not merely isomorphic to an array, it is an array: the isomorphism is implemented by the compiler. Many other isomorphisms are not implemented for example there is an isomorphism expressed by the following client code: match v with | ((?x,?y),?z = x,(y,z) // Felix match v with | (x,y), - x,(y,z) (* Ocaml *) As another example, a type constructor C of int in Felix may be used directly as a function, whilst in Ocaml you must write a wrapper: let c x = C x Another isomorphism Felix implements is the elimination of unit values, including those in tuples: Felix can do this because (most) polymorphic values are monomorphised which can be done because it is a whole program analyser, Ocaml, for example, cannot do this easily because it supports separate compilation. For the same reason Felix performs type-class dispatch at compile time whilst Haskell passes around dictionaries. There are some quite surprising issues here. For example an array is just a tuple, and tuples can be indexed at run time using a match and returning a value of a corresponding sum type. Indeed, to be correct the index used is in fact a case of unit sum with N summands, rather than an integer. Yet, in a real implementation, if the tuple is an array the index is replaced by an integer with a range check, and the result type is replaced by the common argument type of all the constructors: two isomorphisms are involved here, but they're implemented partly in the compiler translation and partly at run time.

  i just downloaded sublime text for my ubuntu, and its working fine. i have the executable file in my ~/sublime folder. now i would like to invoke this app from the terminal by just typing sublime. i suppose that is possible, pls let me know how. also, since this application did not need any configure/make/install (i just had to extract it and then use the exec file to run the app), i cannot add this to my gnome launcher fav apps panel. how can i put the app shortcut there, so that when i do a top-left and then type sublime, the results will show the applicaion and then i can click on it and invoke the app from there? thanks!

• APIs that deal with logins

  - by Brandon Still

  I have been asked to make a mobile app for a friends website. The website is a Multi level marketing site that sells products and franchises. A client logs in in to the website and can view his or her dashboard ( user can view team members, business volume, commissions, invoices, etc.) The app is supposed to bring the dashboard to user's mobile devices (w/ some added features). The company does not have any APIs that deal with interaction or authentication, and I am new to the whole secure login side of app development. My questions is this, how do I let the users gain access to their information via my app from the secure website when there is no API?

• Design for object with optional and modifiable attributtes?

  - by Ikuzen

  I've been using the Builder pattern to create objects with a large number of attributes, where most of them are optional. But up until now, I've defined them as final, as recommended by Joshua Block and other authors, and haven't needed to change their values. I am wondering what should I do though if I need a class with a substantial number of optional but non-final (mutable) attributes? My Builder pattern code looks like this: public class Example { //All possible parameters (optional or not) private final int param1; private final int param2; //Builder class public static class Builder { private final int param1; //Required parameters private int param2 = 0; //Optional parameters - initialized to default //Builder constructor public Builder (int param1) { this.param1 = param1; } //Setter-like methods for optional parameters public Builder param2(int value) { param2 = value; return this; } //build() method public Example build() { return new Example(this); } } //Private constructor private Example(Builder builder) { param1 = builder.param1; param2 = builder.param2; } } Can I just remove the final keyword from the declaration to be able to access the attributes externally (through normal setters, for example)? Or is there a creational pattern that allows optional but non-final attributes that would be better suited in this case?

• Webmaster Tools - Preferred Domain and Google entries

What would happen if we switched the preferred domain in webmaster tools to somethingelse.com? Our client is hoping it will replace the "example.com" result with "somethingelse.com" but I assume this is not the case.

• What are my options for selling software independently on Windows?

  - by technomalogical

  I am looking to port a tool from the Mac app store over to Windows, the platform where I spend most of my time these days. I've spoken with the author of the original app and we've begun talking about licensing options should I decide to sell the application, and it seems like it would be feasible.

Assuming my product was done today and I was ready to go to market, what options do I have for selling software for Windows as an independent developer or Micro-ISV?
