• Keeping Your Employees Engaged Requires More Than Bright Shiny Objects

  - by Oracle Accelerate for Midsize Companies

  by Jim Lein | Sr. Principal Product Marketing Director | Oracle Midsize Programs | @JimLein If you are experiencing the challenges of hiring and retaining the best talent then you understand how important it is to keep employees engaged. An engaged employee is "one who understands his/her place in the organization and fully comprehends how they contribute to and participate in the firm's execution of its Mission and Vision". It goes deeper than just what I call "bright shiny objects". During my ski bum days, all my boss at the ski shop had to do was say, "If you put all these boots away before noon you can make a few powder runs and come back for the afternoon rush". That's as bright and shiny as it gets. Pamela Stroko heads up Oracle's HCM Sales Enablement and Development and is Talent Management and Expert and Evangelist. Our Oracle Accelerate quarterly newsletter features a Q&A with Stroko on the Current State of Employee Engagement. Stroko provides perspective on how to keep employees engaged when hiring managers are challenged to find and retain top talent. Read the entire Q&A here. Click here to see the entire newsletter.

• IP Connflict on network

  - by PSU_Kardi

  I keep getting an IP conflict on my home network and can't figure out why. I'm running a Belkin-N wireless router that has an Ethernet connection to my 360 and a wireless connection running to my laptop. It's WPA2 encryption and I have a nice password on my router consisting of letters , numbers and special characters. But for some reason I keep getting IP conflicts at night time...By the time I look into the problem I don't see anyone else on the network. Is my router giving me false positives?

• Retrieve malicious IP addresses from Apache logs and block them with iptables

  - by Gabriel Talavera

  Im trying to keep away some attackers that try to exploit XSS vulnerabilities from my website, I have found that most of the malicious attempts start with a classic "alert(document.cookie);\" test. The site is not vulnerable to XSS but I want to block the offending IP addresses before they found a real vulnerability, also, to keep the logs clean. My first thought is to have a script constantly checking in the Apache logs all IP addresses that start with that probe and send those addresses to an iptables drop rule. With something like this: cat /var/log/httpd/-access_log | grep "alert(document.cookie);" | awk '{print $1}' | uniq Why would be an effective way to send the output of that command to iptables? Thanks in advance for any input!

• Converting Mercurial Repository To Sub Version (SVN)

  - by alexganose

  This may seem like a very strange situation. Initially we were using subversion (SVN) for version control... then we moved to mercurial and used a tool to convert our previous commits to a mercurial form. And now we want to move back to sub version however we can't seem to find anything that will allow us to keep out history from the mercurial commits and keep them in subversion form. Does anyone know if this is possible/ how to go about doing it? Thanks!!

• HTACCESS Rewrite problem

  - by TiuTalk

  I have this folder structure: /var/www/mysite/abc/ /var/www/mysite/def/ /var/www/mysite/fgh/ /var/www/mysite/ijk/ /var/www/mysite/portal/ /var/www/mysite/wyz/ Today's my server is redirecting all requests of www.mydomain.com to www.mydomain.com/portal and that's ok... But I want to modify this behavior and keep www.mydomain.com acessing the /var/www/mysite/portal/ folder on background while www.mydomain.com/abc/ still acessing the /var/www/mysite/abc/ folder as before. That's what i've tried without sucess on my htaccess: IndexIgnore * Options +FollowSymlinks <IfModule mod_rewrite.c> RewriteEngine On #This doesn't work!!! #RewriteCond %{REQUEST_URI} !^abc #Neither this :\ #RewriteCond %{REQUEST_URI} !^/abc RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^$ /portal/index.php [L] RewriteRule . /portal/index.php [L] </IfModule> All requests keep goin to www.mydomain.com/portal/ when I use this .htaccess (with or without the commented lines)

• Sun Java crashing, mostly with jboss

  - by Joel

  I'm on Ubuntu 10.10. I keep having problems with Sun Java crashing on me. I mostly have it crashing on my Jboss server, but I've had it crash MANY MANY times running ANT tasks or the IntelliJ IDE. Here's what it prints: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f67e665d440, pid=21260, tid=140082772170512 # # JRE version: 6.0_22-b04 # Java VM: Java HotSpot(TM) 64-Bit Server VM (17.1-b03 mixed mode linux-amd64 ) # Problematic frame: # V [libjvm.so+0x2f2440] # # An error report file with more information is saved as: # /home/blah/blah/blah/hs_err_pid21260.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # Aborted A co-worker of mine who has the same version of Ubuntu has had the same problem, but has only happened to him once. (I get this probably 2 or 3 times a day, if not more). I have another machine running Ubuntu 10.04 with Sun Java and I have yet to see this problem. 1.0.6_20 is the java version on the 10.04 machine. My machine is running 1.6.0_22. Has anyone else had this problem? Anyone know how to keep it from happening? Also: I have tried reinstalling it and I can't use OpenJDK.

• Move some iTunes library items to different drive?

  - by Sören Kuklau

  My internal hard drive is somewhat small, and I only regularly listen to a fraction of my iTunes library anyway, so I'd like to keep large portions on it on an external drive for archival purposes. Since dealing with multiple iTunes libraries is somewhat painful, the solution I'm looking for is to move individual items of the library to a different location, without compromising the "Keep organized" and "Copy files" settings. I found an AppleScript that I assume is supposed to do this, Move Files To Folder…, but it instead copies them, and doesn't update the library accordingly. I can do this manually by moving the file, then accessing it in iTunes — it'll prompt me for the new location. I just don't intend to do this one by one for thousands of files.

• Is error suppression acceptable in role of logic mechanism?

  - by Rarst

  This came up in code review at work in context of PHP and @ operator. However I want to try keep this in more generic form, since few question about it I found on SO got bogged down in technical specifics. Accessing array field, which is not set, results in error message and is commonly handled by following logic (pseudo code): if field value is set output field value Code in question was doing it like: start ignoring errors output field value stop ignoring errors The reasoning for latter was that it's more compact and readable code in this specific case. I feel that those benefits do not justify misuse (IMO) of language mechanics. Is such code is being "clever" in a bad way? Is discarding possible error (for any reason) acceptable practice over explicitly handling it (even if that leads to more extensive and/or intensive code)? Is it acceptable for programming operators to cross boundaries of intended use (like in this case using error handling for controlling output)? Edit I wanted to keep it more generic, but specific code being discussed was like this: if ( isset($array['field']) ) { echo '<li>' . $array['field'] . '</li>'; } vs the following example: echo '<li>' . @$array['field'] . '</li>';

• Suggestions? Password & Encrypted Read/Write File like a Mac (.dmg or .SparseBundle) also R/W on Windows, Ubuntu

  - by Jeff Drew

  For years I have used .dmg or .sparsebundle (Encrypted and Password Protected) to safely keep home directory backups on my Mac. Now, I am looking for a similar Full Permissions/Read/Write that maintains an encrypted, and password protected file that it Tri-Platform. I'd like to have the future ability to use it on Mac OS X, Windows 7/8, and Ubuntu (current releases+). I appreciate your recommendations. Thank you. (I like mounting a DMG and having a file directory structure that can be easily maintained and organized. When done, un-mounting the file.) (I've seen Windows tools to open encrypted DMG files? and I will explore these options, but with the desire to also keep the file accessible on on three OSes, someone might have additional suggestions.)

• Implementing new required feature after software release

  - by TiagoBrenck

  Fake Scenario There is a software that was released 1 year ago. The software is to map and register all kind of animals on our planet. When the software was released, the client only needed to know the scientific name of the animal, a flag if it is in risk of extinction and a scale of dangerous(that is a fake software and specification, I don't want to discuss this here). There are already 100.000 animals records saved on DB. New Feature One year later, the client wants a new feature. It is really important to him to know the animals classes, and this is a required field. So he asks me to put a field to input the animal class, and this field is required. Or maybe where this animal was discovered. Problem I have already 100.000 recorded animals without a class or where it was discovered, but I need to insert a new column to storage this information and this column can't be null. I don't have a default value for this situation (there isn't a default animal class or where it was discovered). I don't want to keep the requirement rule only on my software, my DB must have this requirement too(I like to keep business rules on DB too). What are the alternatives to solve this situation? I am on a situation that this new feature cannot be previewed or reviewed for the existing records. The time already passed and I can't go back on time to get it

• Where to put unix sockets

  - by James Willson

  I am new to this, so sorry if its obvious. I am running a debian server and installing the likes of UWSGI, NGinx etc on there. The configurations keep talking about pointing to "sockets". In the build options I seem to be able to specify where the sockets for each program go. By default it looks like most of them go in /tmp/ (not all of them). Is this a good place for them to go? Im trying to keep things as organised as possible but just bunging them in my tmp directory doesnt seem like the best option.

• In what fields do programming and Business Sciences intersect? [on hold]

  - by Alainus

  One note of clarification: I'm getting a lot of comments saying that this question is too personal, too relative, subjective, and that career-path questions get quickly deleted. This is not a question about me or my career. This question is just what the title says: What fields exist that converge programming and business. Now the question: I read this answer regarding off-topic questions, and I was afraid this might be, so I'll try to keep it general and helpful for others. Also, this one has a similar background but formulates a different question from it. I have a Business Administration degree, but I've programmed since I can remember, and it's been my only job for years. However, my problem is the same that the majority of "amateuressional" programmers have: - Incomplete knowledge of the fundamentals. - Anxiety to keep up. - Feeling of not making anything useful of "the other degree". - Afraid of finally becoming a jack of all trades (master of none). Which further studies (specific degrees or fields) exist that allow a person with a BS degree converge into a programming career, without having to sacrifice coding, allowing to further expand the knowledge of C.S. fundamentals, and also without completely sacrificing the first?

• Lots of spambot registrations on PHPBB forum

  - by Dreamdealer

  We have a PHPBB forum running for a few years with admin approval of newly registred users. New users can not post on the forum untill we approve their new account. So I get an e-mail for every new registration, and sometimes there are spambot registrations amongst them. But untill yesterday this was only a few a year, but overnight I got 32 (!) new registrations and they keep rolling in every 15 minutes or so. I run the latest PHPBB version and spambot countermeasures are on. We first had the ReCaptcha option, but that didn't work well. Then we changed it to a Q&A version and that worked. I changed the question an hour ago, but the new spam registrations keep happening, whatever I do. Help!

• Switch to another CPanel server, restore mailbox, how to stop Outlook POP3 pull mail data again.

  - by Shiro

  Hi, We switch from a linux CPanel server to another CPanel server, all the setting and file is restore back to the new Linux CPanel server. E.g [email protected] , inside the server I got 100mails. It had been downloaded to my Outlook, my outlook also got 100 mails inside. After I switch to new server, the 100 mail in the old server had been transfer to new server. However, when I open my Outlook, it start to download the 100 mails again, that means I got 200 mails in my mailbox and it is duplicated. How can I stop Outlook to download. The time stamp, receiver and sender is exactly the same. We want to keep a backup in the server, because we don't have a physical server to keep the mail. That why we would like to transfer the mailbox to the new server. Anyone have solution to stop Outlook download again?

• How should I start refactoring my mostly-procedural C++ application?

  - by oob

  We have a program written in C++ that is mostly procedural, but we do use some C++ containers from the standard library (vector, map, list, etc). We are constantly making changes to this code, so I wouldn't call it a stagnant piece of legacy code that we can just wrap up. There are a lot of issues with this code making it harder and harder for us to make changes, but I see the three biggest issues being: Many of the functions do more (way more) than one thing We violate the DRY principle left and right We have global variables and global state up the wazoo. I was thinking we should attack areas 1 and 2 first. Along the way, we can "de-globalize" our smaller functions from the bottom up by passing in information that is currently global as parameters to the lower level functions from the higher level functions and then concentrate on figuring out how to removing the need for global variables as much as possible. I just finished reading Code Complete 2 and The Pragmatic Programmer, and I learned a lot, but I am feeling overwhelmed. I would like to implement unit testing, change from a procedural to OO approach, automate testing, use a better logging system, fully validate all input, implement better error handling and many other things, but I know if we start all this at once, we would screw ourselves. I am thinking the three I listed are the most important to start with. Any suggestions are welcome. We are a team of two programmers mostly with experience with in-house scripting. It is going to be hard to justify taking the time to refactor, especially if we can't bill the time to a client. Believe it or not, this project has been successful enough to keep us busy full time and also keep several consultants busy using it for client work.

• Messaging with KnockoutJs

  - by Aligned

  MVVM Light has Messaging that helps keep View Models decoupled, isolated, and keep the separation of concerns, while allowing them to communicate with each other. This is a very helpful feature. One View Model can send off a message and if anyone is listening for it, they will react, otherwise nothing will happen. I now want to do the same with KnockoutJs View Models. Here are some links on how to do this: http://stackoverflow.com/questions/9892124/whats-the-best-way-of-linking-synchronising-view-models-in-knockout http://www.knockmeout.net/2012/05/using-ko-native-pubsub.html ~ this is a great article describing the ko.subscribable type. http://jsfiddle.net/rniemeyer/z7KgM/ ~ shows how to do the subscription https://github.com/rniemeyer/knockout-postbox will be used to help with the PubSub (described in the blog post above) through the Nuget package. http://jsfiddle.net/rniemeyer/mg3hj/ of knockout-postbox   Implementation: Use syncWith for two-way synchronization. MainVM: self.selectedElement= ko.observable().syncWith (“selectedElement”); ElementListComponentVM example: self.selectedElement= ko.observable().syncWith(“selectedElement”); ko.selectedElement.subscribe(function(){ // do something with the seletion change }); ElementVMTwo: self.selectedElement= ko.observable().syncWith (“selectedElement”); // subscribe example ko.postbox.subscribe(“changeMessage”, function(newValue){ }); // or use subscribeTo this.visible = ko.observable().subscribeTo("section", function(newValue) { // do something here }); · Use ko.toJS to avoid both sides having the same reference (see the blog post). · unsubscribeFrom should be called when the dialog is hidden or closed · Use publishOn to automatically send out messages when an observable changes o ko.observable().publishOn(“section”);

• Windows 7 keeps losing drive letters

  - by Dean Perry

  Windows 7 loses its drive letters and I have to keep manually assigning a drive letter everytime I plug in a hard drive, whether it's internal or external. The only way to get around it is to reinstall Windows 7 but the problem will come back after a few months. We are a PC repair company and plug in many drives during the say and it can be very frustrating having to keep assigning a drive letter every time a drive is plugged in. Windows Updates are turned off so it can't be that. Any reason why this would have happened?

• Leadership Tip&ndash;Vent Up!

  - by D'Arcy Lussier

  Leadership is difficult, for many reasons. One of those reasons is that we not only need to keep ourselves motivated when difficult or challenging times come, but we also need to motivate our teams and keep them focussed on the tasks at hand regardless of the mortars being rained down around them. Inexperienced (and experienced) leaders can fall into the “me-too” mentality – that is, the leader sees themselves as part of the team member instead of the leader of the team. Once a leader changes the teams view that he/she is a peer and not the leader, dynamics can change on the team. One of the biggest dangers is that the leader starts sharing frustrations, fears, concerns, etc. with the team that they’re supposed to be leading on to victory. This can destroy a team’s morale and productivity. One simple thing you can do to counter this is remember this rule when it comes to venting: Vent Up! Don’t vent sideways or down, vent up. Vent to the people above you – they’re the ones that tend to have the power to actually change things anyway. You as a leader stay healthy by getting your frustrations and concerns off your chest, your team is still insulated from it, and your superiors are aware of issues that need to be addressed or can coach you through the obstacles.

• What is the cleanest way to upgrade Fedora and also my individual installs while keeping /home?

  - by Don

  I am a professional programmer, using Fedora 10 (and a host of other packages individually installed). I use my system to telecommute. Every year or so, I go through the ritual dance, usually with a second computer and a KVM switch as I don't have office space for two monitors, to build the next version of Fedora and install all my favorite apps. Is there a better way? At least a nice way to keep track of what I need to 'add on' so that I don't have to manually install my app collection? Also, I keep /home on a separate raid-ed drive set so I can also fall prey to 'old-config-file-itis'.

• Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

  - by bensch

  I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.

• How to store a list of Objects that might change in future?

  - by Amogh Talpallikar

  I have set of Objects of the same class which have different values of their attributes. and I need to find the best match from a function under given scenarios out of these objects. In future these objects might increase as well. Quite similar to the way we have Color class in awt. we have some static color objects in the class with diff rgb values. But in my case say, I need to chose the suitable color out of these static ones based on certain criteria. So should I keep them in an arrayList or enum or keep them as static vars as in case of Colors. because I will need to parse through all of them and decide upon the best match. so I need them in some sort of collection. But in future if I need to add another type I will have to modify the class and add another list.add(object) call for this one and then it will violate the open-close principle. How should I go about it ?

• Using a CDN for CMS software (multiple sites)

  - by SmokeyPHP

  I'm currently researching ideas for the media management side of a CMS I'm writing. I was looking at having images served from a CDN which is fine on a single site, but I want all sites that run the CMS to make use of a CDN (which will most likely be a custom developed one, rather than a third party service like S3). My main question is: Is a multi-site CDN a good idea? I can't think of a downside, but have probably missed something - obviously they won't share the same folder, as I invisage the requests to be css.cdnsite.com/example.com/style.css or something along those lines. Having multiple sites in the same place will obviously make it easier for us to manage, as well as being cheaper, but then I wonder if it'll be worth it... Long story short: How should the CMS handle user uploaded media (separate installations) Just keep a local copy of all assets and serve them from the same site, like in days of yore? Keep a local copy, force site to use www. and have CDN subdomains per site? Or use a single separate CDN for all sites? Apologies for the length of this question, not sure if this should be multiple questions or not, as all parts are kind of related and could affect each other.

• How do I change the canvas size of a PNG with ImageMagick (GraphicsMagick)? (How to pad with transparency?)

  - by Pistos

  Alternatively: How do I take a non-square PNG and "fill out" the "rest" of the image with transparency so that the resulting square image has the original image centered in the square? ULTIMATELY, what I want is to take any image of any GM-supported format of any size, and create a scaled-down PNG (say, 40 pixels maximum for either dimension), with aspect ratio maintained, transparency-padded for non-square original images, AND with an already-prepared 40x40 PNG transparency mask applied. I already know how to scale down and keep aspect ratio; I already have the command for applying my composite. My only missing piece is square-alizing non-square images (padding with transparency). Single command preferred; multi-command chain acceptable. (edit) Extra info: Here's the composite command I'm using: gm composite -compose copyopacity mask.png source-and-target.png source-and-target.png where mask.png has white pixels for what I want to keep of source-and-target.png and transparent pixels for what I want to remove (and become transparent) of source-and-target.png.

• How to configure something like "Reflexive ACL" on OpenBSD?

  - by Earlz

  My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?
