  • Book: DevOps for Developers

    - by Tori Wieldt
    We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

  • Book / software to learn ERP?

    - by user22311
    For a while I've been wanting to learn ERP. What I would like to do is set up a system, and then practice running a business doing things like generating invoices, raising purchase orders, producing monthly accounts, keeping track of fixed assets etc. Then look at enhancing the system further by adding custom code. I know there are a variety of open source ERP systems around, but really I would prefer a widely used commercial system as having familiarity with such a system would be more marketable. So are there any such systems that have a free developer version available? I've looked around, but I've had trouble finding such a system. Also I would like to find a good book or more likely books to read on ERP. Ideally I would be able to get an indepth explanation ERP from a business perspective, ie the accounting operations it supports, how to do all the regular accounting tasks, configuration, business operations best practices, accounting controls and so on. In addition I would like an IT perspective, ie setting up the system, developing forms and reports. Unfortunately the few books I've looked at have been really superficial and totally inadequate. They either fall into the beginning programmer camp, where they use the programming tools but concentrate on programming 101 topics like loops, flow control etc. Or they cover setting up the system with lots of screen shots, but little substance as to why things should be done a certain way. I have a programming background but no real experience in implementing ERP systems. Also I have a reasonable accounting knowledge, and have used ERP systems in various jobs, but only to a very limited degree. So are there any ERP experts who can point me in the right direction? Thanks.

  • How to change the MAC address in Win 8 to spoof a Roku Player through a WiFi splash page?

    - by luser droog
    My Linux laptop died yesterday and now I can't watch TV. Let me explain. I use a Roku Player to stream Netflix shows to my television; and a year or two ago, the Internet Service provided in my apartment complex added a Splash Page to get through the router and onto the net. After not too many days, I remembered that internet devices identify themselves with a MAC address. So I delved into the manpage of ifconfig and discovered that I could persuade my laptop to pretend to be the Roku Player, connect, click through the Splash Page, disconnect and change it back. This would allow the Roku to connect for about 24 hours, when I would have to do it again. But the laptop died yesterday during my smoke break. So during lunch, I ran to OfficeMax and got a new one. But I don't know where to begin looking for where to change the MAC address (assuming it's possible). I know I can try dual-boot, or a keychain OS, or possibly other things to resurrect my old method. But, is it possible to get Windows do it?

  • Explanation of the definition of interface inheritance as described in GoF book

    - by Geek
    I am reading the first chapter of the Gof book. Section 1.6 discusses about class vs interface inheritance: Class versus Interface Inheritance It's important to understand the difference between an object's class and its type. An object's class defines how the object is implemented.The class defines the object's internal state and the implementation of its operations.In contrast,an object's type only refers to its interface--the set of requests on which it can respond. An object can have many types, and objects of different classes can have the same type. Of course, there's a close relationship between class and type. Because a class defines the operations an object can perform, it also defines the object's type . When we say that an object is an instance of a class, we imply that the object supports the interface defined by the class. Languages like c++ and Eiffel use classes to specify both an object's type and its implementation. Smalltalk programs do not declare the types of variables; consequently,the compiler does not check that the types of objects assigned to a variable are subtypes of the variable's type. Sending a message requires checking that the class of the receiver implements the message, but it doesn't require checking that the receiver is an instance of a particular class. It's also important to understand the difference between class inheritance and interface inheritance (or subtyping). Class inheritance defines an object's implementation in terms of another object's implementation. In short, it's a mechanism for code and representation sharing. In contrast,interface inheritance(or subtyping) describes when an object can be used in place of another. I am familiar with the Java and JavaScript programming language and not really familiar with either C++ or Smalltalk or Eiffel as mentioned here. So I am trying to map the concepts discussed here to Java's way of doing classes, inheritance and interfaces. This is how I think of of these concepts in Java: In Java a class is always a blueprint for the objects it produces and what interface(as in "set of all possible requests that the object can respond to") an object of that class possess is defined during compilation stage only because the class of the object would have implemented those interfaces. The requests that an object of that class can respond to is the set of all the methods that are in the class(including those implemented for the interfaces that this class implements). My specific questions are: Am I right in saying that Java's way is more similar to C++ as described in the third paragraph. I do not understand what is meant by interface inheritance in the last paragraph. In Java interface inheritance is one interface extending from another interface. But I think the word interface has some other overloaded meaning here. Can some one provide an example in Java of what is meant by interface inheritance here so that I understand it better?

  • Potential issues using member's "from" address and the "sender" header

    - by Paul Burney
    Hi all, A major component of our application sends email to members on behalf of other members. Currently we set the "From" address to our system address and use a "Reply-to" header with the member's address. The issue is that replies from some email clients (and auto-replies/bounces) don't respect the "Reply-to" header so get sent to our system address, effectively sending them to a black hole. We're considering setting the "From" address to our member's address, and the "Sender" address to our system address. It appears this way would pass SPF and Sender-ID checks. Are there any reasons not to switch to this method? Are there any other potential issues? Thanks in advance, -Paul Here are way more details than you probably need: When the application was first developed, we just changed the "from" address to be that of the sending member as that was the common practice at the time (this was many years ago). We later changed that to have the "from" address be the member's name and our address, i.e., From: "Mary Smith" <[email protected]> With a "reply-to" header set to the member's address: Reply-To: "Mary Smith" <[email protected]> This helped with messages being mis-categorized as spam. As SPF became more popular, we added an additional header that would work in conjunction with our SPF records: Sender: <[email protected]> Things work OK, but it turns out that, in practice, some email clients and most MTA's don't respect the "Reply-To" header. Because of this, many members send messages to [email protected] instead of the desired member. So, I started envisioning various schemes to add data about the sender to the email headers or encode it in the "from" email address so that we could process the response and redirect appropriately. For example, From: "Mary Smith" <[email protected]> where the string after "messages" is a hash representing Mary Smith's member in our system. Of course, that path could lead to a lot of pain as we need to develop MTA functionality for our system address. I was looking again at the SPF documentation and found this page interesting: http://www.openspf.org/Best_Practices/Webgenerated They show two examples, that of evite.com and that of egreetings.com. Basically, evite.com is doing it the way we're doing it. The egreetings.com example uses the member's from address with an added "Sender" header. So the question is, are there any potential issues with using the egreetings method of the member's from address with a sender header? That would eliminate the replies that bad clients send to the system address. I don't believe that it solves the bounce/vacation/whitelist issue since those often send to the MAIL FROM even if Return Path is specified.

  • Domain forwarding with url substitution in the address bar

    - by Mario Duarte
    Hello, I have a blog being served by a machine I have at home. Since the ip can change i set up a dyndns domain to always point to that machine. However, I purchased a more friendly domain (at godaddy.com) and I would like to forward it to that blog. The problem is that if I simply forward it the users will see the dyndns domain in the address bar and could potentially bookmark those urls and that's a problem. I noticed that godaddy.com has domain masking and although it does hide the dyndns domain in the address bar, it also keeps the same root address in the address bar even if I navigate to another page. I also have the feeling that search engines will not like this domain masking thing. Does anyone know how can I accomplish what I want?

  • SQL SERVER – Selecting Domain from Email Address

    - by pinaldave
    Recently I came across a quick need where I needed to retrieve domain of the email address. The email address is in the database table. I quickly wrote following script which will extract the domain and will also count how many email addresses are there with the same domain address. SELECT RIGHT(Email, LEN(Email) - CHARINDEX('@', email)) Domain , COUNT(Email) EmailCount FROM   dbo.email WHERE  LEN(Email) > 0 GROUP BY RIGHT(Email, LEN(Email) - CHARINDEX('@', email)) ORDER BY EmailCount DESC Above script will select the domain after @ character. Please note, if there is more than one @ character in the email, this script will not work as that email address is already invalid. Do you have any similar script which can do the same thing efficiently? Please post as a comment.

  • SSL and green address bar

    - by tinab
    I am new to SSL so can someone explain why my address bar turns green when I'm on certain sites beginning with https:// and sometimes it doesn't even though I know the site has SSL? Maybe these two nuances are not even related, but if I go to GoDaddy and order a new domain I notice their address bar is green the entire time I'm using the https:// protocol, but then I go to Victoria's Secret to place an order and even though it says https:// the address bar doesn't turn green.

  • Changing internal home network ip address for connected devices

    - by oshirowanen
    I have a few computers at home. For each of the computers, I can see the internal home network ip address on any given device by typing in ifconfig in the terminal. If the device is connected to the home network via ethernet connection or via the built-in wireless connections in laptops, the internal ip address for each of the devices seems to be 192.168.0.X. However, when I connect one of the devices using an external usb modem wireless adapter, which connects to the home network through wireless, when I check the ip address via ifconfig, for some reason it gets assigned 192.168.42.X instead. Why are the ethernet and build in wireless connections getting 192.168.0.X, but the external usb wireless adapter gets 192.168.42.X? Most importantly, is it possible to force it to get an internal ip address of 192.168.0.X?

  • What regular expression can I use to match an IP address?

    - by jennifer
    With the following grep syntax I want to match all IP address in a file (from a ksh script) grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' file The problem: It also matches words (IP) that have more then 4 octets: 1.1.1.1.1 or 192.1.1.1.160 How can I match a valid IP and only IP addresses with 4 octets? I can also use Perl – a one line syntax solution, if grep doesn't work.

  • Configuring the expiry time for the messages destined to the "Expired message address" in Hornetq

    - by Rohit
    I have configured a message expiry destination in Hornetq as below <address-setting match="#"> <dead-letter-address>jms.queue.error</dead-letter-address> <expiry-address>jms.queue.error</expiry-address> <max-delivery-attempts>3</max-delivery-attempts> <redelivery-delay>2000</redelivery-delay> <max-size-bytes>10485760</max-size-bytes> <message-counter-history-day-limit>10</message-counter-history-day-limit> <address-full-policy>BLOCK</address-full-policy> <redistribution-delay>60000</redistribution-delay> </address-setting> And the messages do get redirected to the expiry address once the expiration time is exceeded. These messages live indefinitely on the expiry address, Is there a way to provide a expiry time for these messages so they live only limited time on the expiry address?

  • How to transition to Comcast with static IP address

    - by steveha
    I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

  • Exchange 2007 Email Address Policies

    - by Ryan Migita
    We have recently upgraded to Exchange 2007 (from 2003) and have noticed the change from recipient policies to email address policies. We have two separate domains (let's call them domaina.com and domainb.com) we receive email for, have email address policies and both email address policies are not applied. In our Exchange 2003 environment, domaina.com was the default email address when we created new mailboxes and due to the migration, domainb is the default (and its email address policy is a higher priority). Now, when we create a new mailbox (or edit existing ones), the primary email address becomes domainb.com. Now the question is, is this as simple as putting the email address policies in the correct order? Do I have to apply both policies? What effect will the above changes make to existing mailboxes? Since we do not have any conditions set on the policies, I assume prior to making these changes, I should force all domainb mailboxes to not automatically update email address based on policy? Thanks in advance!

  • Adding a second IP address for IIS - static vs dynamic A records

    - by serialhobbyist
    I'm looking to add a second IP address to IIS so that I can run two sites with different SSL certificates. When I added one on my play box and ran ipconfig /registerdns both addresses were registered in DNS with the server's name. So, I deleted the A record for the new IP address and rebooted. That also registered both names. So, then I went into the network config for the adapter and, on the DNS tab, unchecked "Register this connection's addresses in DNS". I deleted the A record for the new IP address again and re-ran ipconfig /registerdns. This time, it deleted the A record for the old IP address and didn't created one for the new address. Neither of these is what I want: I want the main IP address to be registered and refreshed automatically as a dynamic DNS record and the second IP address to be registered and managed as a static address. Is there any way to achieve this?
