  • How to build Object Oriented Skills?

    - by cedar715
    Being a core developer for couple of years, coding applications seeing the class diagrams, sequence diagrams, I decided to improve my self, taking the next step of designing. As I'm an OO developer, I'm interested in improving my design skills. For Example, I had a hard time designing a currency converter. My questions to the SO: Is it by experience the design skills can be acquired? Will learning books/blog/material over internet etc help? Is it that one needs the domain knowledge of the application being developed? Knowing Design patterns, principles? Studying 'Code Complete' book ? Need to have Problem-solving skills? In short, given a problem, I just want to solve it in Object-oriented way??

  • UNC vs. SFTP vs. SSH for uploading to a Windows server

    - by apollodude217
    I understand that UNC, SFTP, and SSH are, of course, different interfaces (protocols?). But feature-wise, how do they differ? Are there things you can do with one that you cannot do with another? Is one more secure than another? The situation I want to fix is one where we have several Windows servers and VPC's, some of which have SFTP servers and some of which don't. For those that don't we use UNC over a VPN shared by the entire enterprise. What I want to do is either use all UNC, all SFTP, or all SSH (unless a real need to vary on a case-by-case basis presents itself). Links would be excellent. My biggest problem here is that my googling brings up irrelevant results. :(

  • Cable installed - now my hub has no connection the router/modem - what do I need to buy?

    - by bcmcfc
    My previous setup was as follows: [modem/router]------[switch]+------ [pc1] +------ [pc2] I've just moved and had cable installed and I no longer have the option of running a lengthy LAN cable from the router to the switch to provide network and internet access to the two PCs. The cable company provided 2 wireless N USB adapters. What do I need to buy to plug into where in order to restore the network to its previous state? PC1 dual boots Windows 7 and Ubuntu 12. PC2 runs Debian 6. Edit: USB adapters - Netgear WNDA3200 Switch - TP-Link TL-SF1008D 8 port Ethernet switch Cabling - various patch cables cat5e rj45 Modem/Router - pretty standard cable company job - wireless Intention is something like- [modem/router] --wifi-- [some-new-hardware or perhaps to pc1] ----[switch]---[pc1/2]

  • Hyper-v vs Virtualbox

    - by user53864
    I am using Oracle VirtualBox for ubuntu guest virtual servers on windows server 2008 R2. I'm in a plan to migrate(stop using virtualbox) from VirtualBox to Hyper-V. I guess many are using hyper-v virtualization and have good control over it and could help me here in clarifying few things. The reason I use Virtualbox is it's open source and the reason for migrating is that if hyper-v support any additional feature which virtualbox doesn't(and I couldn't migrate VBox vms along with all the snapshots). I have following questions to get it clarified. Does hyper-v require any licence or is limited to running particular number of virtual machines?. Is hyper-v capable to export/import VMs along with all the snapshots? Is it possible to run HeadLess VMs like it's done with VirtualBox? Does hyper-v recognize VDI/VMDK? Anybody can suggest me anything?. Thanks!

  • Preventing SSH RSA host key warnings for change of key vs IP address

    - by Adam M-W
    I have a network with DHCP enabled, and also a computer that dual boots operating systems and has different SSH keys on each (and yes, I would like to keep different keys on each rather than copying the same identity/private key to each). Because the IP address does not change between operating systems because the MAC address is the same, when connecting to ssh, even when not using the IP address but the hostname via DNS/mDNS, I get the warning: Warning: the RSA host key for 'hostname' differs from the key for the IP address '192.168.1.172' Offending key for IP in /Users/user/.ssh/known_hosts:37 Matching host key in /Users/user/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? How can I surpress the warning when the hostname differs from the IP address for that hostname, but retain the ability to check host keys are the same for each hostname? (each OS has a unique hostname)

  • SQL Server Authentication vs Windows Authentication

    - by Nandu
    Hi, I am a SQL Server newbie and would really appreciate any help. I have created a new login (test2) with sql server authentication and granted select & vierw definition permission on another schema (test1) to test2. I am however not able to see the objects of test1 in the object explorer. However I can select the objects from the Query Window. Since this new login is being used to develop reports the user would like to view the objects in the Object Explorer. Another user test3 created using windows authentication and similar permissions is able to see test1's objects in the explorer. Please let me if this is the cause and if not how can help test2 see the objects in Object Explorer.

    - by netvope
    VMware ESXi 4 supports VMI paravirtualization for 32-bit OS but not for 64-bit OS. For performance consideration, is it better to use a 32-bit Ubuntu Server guest without paravirtualization or a 64-bit one with VMI paravirtualization? Hardware: Core 2 Quad, 8 GB RAM Workload: Software development/testing, webserver, database

  • xinet vs iptables for port forwarding performance

    - by jamie.mccrindle
    I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

  • mongod fork vs nohup

    - by Daniel Kitachewsky
    I'm currently writing process management software. One package we use is mongo. Is there any difference between launching mongo with mongod --fork --logpath=/my/path/mongo.log and nohup mongod >> /my/path/mongo.log 2>&1 < /dev/null & ? My first thought was that --fork could spawn more processes and/or threads, and I was suggested that --fork could be useful for changing the effective user (downgrading privileges). But we run all under the same user (process manager and mongod), so is there any other difference? Thank you

  • Qt Creator CONFIG (debug, release) switches does NOT work

    - by killdaclick
    Problem: CONFIG(debug,debug|release) and CONFIG(release,deubg|release) are always evaluated wherever debug or release is choosen in Qt Creator 2.8.1 for Linux. My configuration in Qt Creator application (stock - default for new project): Projects->Build Settings->Debug Build Steps: qmake build configuration: Debug Effective qmake call: qmake2 proj.pro -r -spec linux-gnueabi-oe-g++ CONFIG+=debug Projects->Build Settings->Release Build Steps: qmake build configuration: Release Effective qmake call: qmake2 proj.pro -r -spec linux-gnueabi-oe-g++ My configuration in proj.pro: message(Variable CONFIG:) message($$CONFIG) CONFIG(debug,debug|release) { message(Debug build) } CONFIG(release,debug|release) { message(Release build) } Output on console for Debug: Project MESSAGE: Variable CONFIG: Project MESSAGE: lex yacc warn_on debug uic resources warn_on release incremental link_prl no_mocdepend release stl qt_no_framework debug console Project MESSAGE: Debug build Project MESSAGE: Release build Output on console for Release: Project MESSAGE: Variable CONFIG: Project MESSAGE: lex yacc warn_on uic resources warn_on release incremental link_prl no_mocdepend release stl qt_no_framework console Project MESSAGE: Debug build Project MESSAGE: Release build Under Windows 7 I didnt experienced any problem with such .pro configuration and it worked fine. I was desperate and modified .pro file: CONFIG = test message(Variable CONFIG:) message($$CONFIG) CONFIG(debug,debug|release) { message(Debug build) } CONFIG(release,debug|release) { message(Release build) } and I was suprised with the output: Project MESSAGE: Variable CONFIG: Project MESSAGE: test Project MESSAGE: Debug build Project MESSAGE: Release build so even if I completly clean CONFIG variable it still see debug and release configuration. What Im doing wrong?

  • Can't Get ANT build to work in eclipse

    - by Travis
    Long story short: I want to add the --core-library flag at compile time to include a library that depends on some javax libraries that aren't included in the android platform. I have attempted the walkthrough here: http://commons.apache.org/scxml/usecases/scxml-stopwatch-on-android.html but nothing ever changed on the emulator. I don't think I can repackage the libraries I'm after because I cannot amend the callers to call the new packages without violating a license agreement. Please, someone, point me in the right direction.

  • HP DL160 G6 memory PC3-10600R vs PC3-10600E

    - by Jeremy Hajek
    I am using a HP DL 160 G6 server that according to specs takes PC3 Registered or Unbuffered. When I combine the two types of memory below the system will not POST. When I use just the first type of memory listed the system will POST. I have two pieces of HP memory that came with the server labeled PC3-10600E-9-10-E0 and then I have some Crucial memory labeled PC3-10600R-9-10-B0 I wager that the R means Registered memory and the E means ECC - then shouldn't the crucial memory boot with the system according to the HP specs? Or does the E mean it is Unbuffered and therefore I shouldn't mix and match as according to this HP memory config doc?

  • Right method to build a online whiteboard - JAVA

    - by Nikhar Sharma
    I am building a whiteboard, which would have a server(teacher) and clients(students). Teacher would draw something on his side, which will be shown exactly same to the students. I want to know which component i should use to do the drawing? i am currently drawing on JPanel . I want the screen of Server gets copied on the clients, so for that what could be the right method to do this? option1: i save the JPanel as image, and send thru socket, and loads it on the screen of client, also it always saves the background image only, not what the user has drawn onto it. OR option2: both server and client JPanel dimensions are same, so i just send the new coordinates drawn everytime thru socket, with some protocol to understand whether it is rubber or pencil.. Any help would be appreciated.

  • tomcat vs FULL J2EE Solutions

    - by jrhickey
    We are getting ready to make a major revision in our Web Application architecture which currently is running on JBoss 4.2. At first we were looking at moving from 4.2 to JBoss 6 but after some research tomcat may be a better solution for us. My first question is their anything that JBoss can do that tomcat cannot do assuming you are using the correct plugins. We do not really use EJB's in our solution and it would appear there are simple plugins for web services, JMX and other features. Tomcat appears to have much better support, faster upgrade cycles and many, many books. Since there is less to the system it also seems much easier to support from an admin point of view. What am I missing? The main features we want to enable are better clustering support and session replication / persistence. We will consider other application servers as well such as Glassfish / Geronimo. quote form a web article: Apache Tomcat is the world’s most widely used web application server, with over one million downloads per month and over 70% penetration in the enterprise datacenter. Tomcat is used to power everything from simple one server sites to large enterprise networks.

  • How to build and deploy Python web applications

    - by sverrejoh
    I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers? Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution. I've been looking a bit into zc.buildout, but it's not clear for me what I can/should use it for.

  • How do I build a specialized JQuery Timer

    - by Sayem Ahmed
    I have an asp.net page where two grid views are available showing current stock market price updates. I need to update these two grid views every 20 seconds. So I was thinking of using JQuery to do this job. What I need is a timer which will fire every 20 seconds, send an ajax request to the servers, bring the order lists from the server using json and then update those two grid views. If a request to the server is still being served 20 seconds after it is fired, then I want the old one to be aborted without causing any trouble. I already know how to bring objects using json. I just need to figure out how to send a request every 20 seconds and cancel a request if it is still being server for 20 seconds.

  • Redundant Router and Load Balancing vs. DDoS attack

    - by colgatta
    With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?
