  • About the new Microsoft Innovation Center (MIC) in Miami

    - by Herve Roggero
    Originally posted on: http://geekswithblogs.net/hroggero/archive/2014/08/21/about-the-new-microsoft-innovation-center-mic-in-miami.aspxLast night I attended a meeting at the new MIC in Miami, run by Blain Barton (@blainbar), Sr IT Pro Evangelist at Microsoft. The meeting was well attended and is meant to be run as a user group format in a casual setting. Many of the local Microsoft MVPs and group leaders were in attendance as well, which allows technical folks to connect with community leaders in the area. If you live in South Florida, I highly recommend to look out for future meetings at the MIC; most meetings will be about the Microsoft Azure platform, either IT Pro or Dev topics. For more information on the MIC, check out this announcement:  http://www.microsoft.com/en-us/news/press/2014/may14/05-02miamiinnovationpr.aspx.

  • configuring linux server firewall to allow acces on a certain range of IP addresses

    - by eggman20
    Hi Guys, I'm not sure if this is the right place to ask this but I'm currently trying to get an Ubuntu 10.10 server up and running for the first time and I'm using Webmin for administration. I'm stuck on the setting up the firewall. What I need to do is to ONLY allow a range of IPs (e.g 128.171.21.1 - 128.171.21.100) to access the HTTP server and Webmin. I've seen a lot of tutorials but none of them fits what I needed. Thanks in advance!

  • Is there any chance that my data will get silently corrupted with a robocopy SMB network transfer?

    - by Archagon
    I'm setting up a NAS box for the first time. At the moment, I have most of my data backed up to a few local hard drives, and I intend to transfer all the data to my NAS over ethernet once the RAID array is setup. Since this is all happening over the network, I'm a bit worried about my data getting corrupted silently during transfer. From what I understand, data generally doesn't get corrupted without notice on local transfers because a checksum is performed at some point by the drive or the OS. (This could be totally wrong.) Does the same thing happen with SMB, or is it up to the transferrer to check the integrity of their data? And if it doesn't happen with SMB, is there a protocol that does ensure data integrity? I know that rsync can checksum a transfer, but I'm on Windows and I already have a robocopy configuration that I like. Will my data be safe or do I have to use an external checksum tool to make sure?

  • Analytics on Mobile Phones

    - by Samuh
    Tracking events and setting up Analytics for Websites seems easy. You create an account with one of the Analytics service providers like Google. They give you javascript code that you embed in your pages (whichever event you wish to track) and voila..you're done. I have written a native application for Android phones, which is actually an adaptation of the actual web site. Now, I am required to setup Analytics and tracking for this native application. Question: How to do this on Mobile phones from within a native application? We have Java Script code that works for the original web site. Is there a way to incorporate that in the native application? I know Android supports Java Script via WebViews(Webkit);my application does not have webviews and it is native. Also, I have not worked on JavaScript since school so excuse me if I sound naive. Thanks.

  • Set Up Port-Forwarding on Netgear N300 Router

    - by Smitty
    I have a Netgear N300 router that has DynDNS.org as a preset DDNS option. After setting it up it (unsurprisingly) sent traffic directly to my router. I'm essentially using this to connect remotely to my home (virtual) machine/s. From what I've read, it seems like I need to set up port forwarding. I tried forwarding "all" inbound traffic to a specific IP but that just didn't work. What am I doing wrong? Also, I just noticed I get this error after applying the settings: "The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type"

  • MySQL returning slow queries with result sets bigger than 30 rows

    - by josephs8
    When ever I run a query that exceeds 30 queries the time for the query to run goes from less than a second to over 10 seconds to get data. Example I run a query to return 29 rows, it takes .1 seconds, I run a query to return 31 rows it takes 11.2 seconds. I am running mySQL on Windows 2008 Server Dual Core 2.6Ghz with 3GB of Memory. The machine doesn't run anything else. It does have a instance of MSSQL running on the server but that does not get used at all. This only happens via PHP right now, If I manually run the query on the server it returns it in less than a second. The queries are not complicated either I have included one below: SELECT Name, Value FROM `bis_co`.`departments` LIMIT 31 What would be causing this issue and how can I correct this? Am I missing a configuration setting in MySQL or something. Thanks

  • More NASM with GVim

    - by MarkPearl
    Today I am bashing around with nasm again… some useful things I found… Set the current working directory of gvim to the current file path I have found setting the current working directory of gvim to the file location is very useful, especially if you are wanting to use commands in gvim to run your compiled code. It can be done by typing in the following in the command mode in gvim… cd %:p:h Once you have set it, you can use the ! to run commands you would normally run in the dos shell.. e.g. !dir Compiling code to make an executable There are three thing you need to specify to compile a basic file in name, they are… The output file format The output file name The source file name An example of this would be the following (where you have a file called temp.asm which is the source file) nasm –f bin temp.asm –o temp.com Output file format The –f specifies the output file format (in this case a binary file). To get a list of the available output file formats you can type nasm –hf (for my installation bin is the default, in which case I can omit it) Output file name This is just the name you want the compiled file to be called. For windows machines I specify .com as my default format.

  • ssh freezes when trying to connect to some hosts

    - by NS Gopikrishnan
    When I try to ssh to particular machine/s in a list, The SSH command happens to be freezing. I tried out setting ssh timeout. But then also it's freezes even after the timeout. In verbose mode : OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to x358.x.server.com [10.x.x.x] port 22. debug1: fd 3 clearing O_NONBLOCK debug1: Connection established. debug1: identity file /export/home/sqlrpt/.ssh/identity type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_rsa type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_dsa type 2 At this point it freezes. A work around I thought was to create a child process for each ssh calls and if the process doesn't respond after a timeout - Kill it. But are there any less complex ways, so that I can accommodate it in a shell script itself rather than going for a C/C++ program ?

  • Single-developer GIT workflow (moving from straightforward FTP)

    - by melat0nin
    I'm trying to decide whether moving to VCS is sensible for me. I am a single web developer in a small organisation (5 people). I'm thinking of VCS (Git) for these reasons: version control, offsite backup, centralised code repository (can access from home). At the moment I work on a live server generally. I FTP in, make my edits and save them, then reupload and refresh. The edits are usually to theme/plugin files for CMSes (e.g. concrete5 or Wordpress). This works well but provides no backup and no version control. I'm wondering how best to integrate VCS into this procedure. I would envisage setting up a Git server on the company's web server, but I'm not clear how to push changes out to client accounts (usually VPSes on the same server) - at the moment I simply log into SFTP with their details and make the changes directly. I'm also not sure what would sensibly represent a repository - would each client's website get their own one? Any insights or experience would be really helpful. I don't think I need the full power of Git by any means, but basic version control and de facto cloud access would be really useful.

  • How do I change the "from" field for an e-mail address routed through Gmail? [closed]

    - by bflora
    I have an e-mail address for a domain I own. [email protected] I am redirecting all mail sent to this address over to my main Gmail account automatically. In Gmail, I've added the [email protected] account so I can send and receive mail from it. Problem: The "from" field on all the e-mails this address sends always says "info". I want it to say "Domain.com" so recipients can know where it's coming from. How do I change this? I've looked in gmail but can't seem to spot a setting that controls this.

  • How to set Outlook 2010 to use signatures outside of the default signature folder?

    - by Gregory MOUSSAT
    With Outlook before the 2010 version, it was possible to specify any path for the signatures. With Outlook 2010, the only way is to use those stored into C:\Documents and Setting\UserName\Local Settings\Application Datas\Microsoft\Signature\ I'd like to point the signatures to a network share. Allowing us to modify the signatures into the share, instead of login on every computers each time we are asked to modify them (and this is quite often because the signatures contain logos about current events). We currently use a script to copy the signatures from the share to the local disk when users login.

  • How do I configure ubuntu server's iptables to allow java without opening the floodgates?

    - by rofls
    I'm new to servers, so please bear with me. I have my amateur site running. Problem is, I followed Rackspace's instructions on setting up iptables and am pretty sure that's why the java server I'm trying to use on port 8080 isn't working (it runs the script but my android test app doesn't connect to it). When I try running the same java server script on port 80 it doesn't even start. I also ran nmap on my domain and saw that indeed only port 80 and 22 (for ssh) are responding. Is it possible to run Java and apache happily on the same server? If so, how can I configure my iptables correctly. (I'm aware that I should probably do some sort of filtering in the java server itself, but will figure that out later).

  • Windows 7 - XP Mode - Apache

    - by Howard
    I've setup Virtual PC and XP Mode on my Windows 7 Pro. Using Apache 2.0.52 I have no problems having my website up and running on the Windows 7 machine. But Under VPC/XP Mode the best I can do is Localhost mode. What do I need to do to enable http connections? I need the XP Mode as besides the website I also run a Web BBS and a Dos based (via telnet) BBS. Some of the apps in the Dos BBS just won't work under 64 bit, no matter what setting (capability) are used. Thanks in advance...

  • HP 4530s: Fan is Always On even When Laptop/CPU is Idle

    - by tolitius
    Just bought an HP 4530s from newegg. Laptop is great, but.. The FAN is always on. I did some googling, found it is a known problem, but no easily googlable solution. Tried to: Update BIOS to the latest Disable "CPU fan always on when plugged in" BIOS setting Installed Windows 7 Home (came with), Live CDed Ubuntu, Windows XP Spent 2 hours with horrible HP support Some other things that I can't already recall = spent too much time on it Laptop is not refundable (learned it the hard way, after the fact, by looking at the NEWEGG clever policy that is hidden in "details") I would really appreciate a workable solution / workaround / hack. The laptop is for my friend who will most likely be running Windows XP/7.

  • No MAU required on a T4

    - by jsavit
    Cryptic background One of the powerful features of the T-series servers is its hardware crypto acceleration, which dramatically speeds up the compute intensive algorithms needed to encrypt and decrypt data. Previously, administrators setting up logical domains on older T-series servers had to explicitly assign crypto resources (called "MAU" for historical reasons from the T1 chip that had "modular arithmetic units") to domains that had a significant crypto workload (say, an SSL based web server). This could be an administrative burden, as you had to choose which domains got the crypto units, and issue the appropriate ldm set-mau N mydomain commands. The T4 changes things The T4 is fast. Really fast. Its clock rate and out-of-order (OOO) execution that provides the single-thread performance that T-series machines previously did not have. If you have any preconceptions about T-series performance, or SPARC in general, based on the older servers (which, it must be said, were absolutely outstanding for multi-threaded applications), those assumptions are now obsolete. The T4 provides outstanding. performance for all kinds of workload, as illustrated at https://blogs.oracle.com/bestperf. While we all focused on this (did I mention the T4 is fast?), another feature of the T4 went largely unnoticed: The T4 servers have crypto acceleration "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". This is way way better since you have crypto everywhere by default without having to manage it like a discrete and limited resource. It's a feature of the processor, like doing an integer add. With T4, there is no management necessary, you just have HW crypto everywhere all the time seamlessly. This change hasn't been widely advertised, and some administrators have wondered why there were unable to assign a MAU to a domain as they did with T2 and T3 machines. The answer is that there is no longer any separate MAU, so you don't have to take any action at all - just leave the default of 0. Summary Besides being much faster than its predecessors, the T4 also integrates hardware crypto acceleration so its seamlessly available to applications, whether domains are being used or not. Administrators no longer have to control how they are allocated - it "just happens"

  • What happens when router has been set to incorrect time?

    - by iamrohitbanga
    I have a D-Link router for my home Wi-Fi network. Everyday at least once the internet suddenly goes down. I am simply not able to connect to the Wi-Fi network. If I just restart the router, it starts working. To debug the issue I logged into the admin panel and noticed the time was set to something in 2002. I have set it to the correct time. Will wait to see if that fixes the problem. In the meanwhile I want to know what can go bad when the router has been set to show an incorrect time? What are the kinds of problems expected? My Wi-Fi was working just fine most of the time, but sometimes it lost the connection. Could this be linked to the incorrect time setting?

  • Clustering with Vsphere and Apache load balacing

    - by Anonymous2011
    I was looking at Vsphere to automatically load balance my apache web servers, and mysql servers but will this actually do the job? I know it says it does auto load balancing but not actually sure it quite means what I want to achieve. Is there an easier way to set up a php-apache and mysql cluster within virtual machines? Or are there any guides to clustering? (I have tried googling without much luck) Any help towards understanding/setting up clustering and load balancing within virtual machines appreciated.

  • Computer Says No: Mobile Apps Connectivity Messages

    - by ultan o'broin
    Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".

  • consulting a network admin for rails and php applications

    - by Karo Devos
    Hi I'm a web developer who writes most of the time rails applications. Next month I'm going to switch from my current VPS to linode. I'm wondering how much it would cost to properly set (or teach me how to do it) everything to get my app up and running. My requirements are probably: nginx/apache, REE/ruby, passenger, full blown php environment, system wide RVM, search engine such a sphinx, being able to perform cronjobs. I have some knowledge of unix and I was able to install everything I needed on my development system. However I had quite a few issues setting up everything on my production server.

  • Is a Hostname A Entry necessary?

    - by Citizen
    When I log into WHM, I get this message: The server was unable to lookup an an A entry for its hostname (server226.taxi.com). This is generally because the entry was never added. However this could also be the result of your nameserver(s) being down. If you would like to attempt to automatically add the entry, click here. If I click "here" it does nothing and I still get the message. I'm not hosting websites for other people, just internal projects on our server. Does not having an A Hostname Record affect SEO or anything like that or is this just a convenience when setting up nameservers or something like that?

  • Make a socket as an user but make it readable and writable by another

    - by user1598585
    I have a software that is run under user A, this software creates a socket in /sockets and the socket should be readable and writable by user B. I have tried setting the directory to have ownership A:A or A:B but when user A creates the socket, it ends up with uid A and gid A. Using ACLs has not helped so far, the default mask is preventing the rights to be effective. rw permisions for B will always turn into jusr r. If what I make is not a socket it will work fine. How can I best accomplish this task? (It is for a web-server where the web-application makes the socket and the web-server software forwards requests to it)

  • Windows 2008 x64 displays SP1 when SP2 is installed

    - by Graham Powell
    After setting up a Windows 2008 x64 server (not R2), I installed a number of Microsoft updates. After installing these updates, the computer reports that it has SP1 installed, not SP2. I believe the culprit is KB917607, which allows Windows 2008 to display .hlp files. Now I have to upgrade Internet Explorer on this server, and it won't install without SP2. I am very leery about reinstalling SP2, as I have installed a large number of post-SP2 updates, and I've had issues after reinstalling SP2 in similar circumstances. How can I fix Windows so it reports the correct service pack?
