• What's the benefit to learn Java programming?

  - by user30139

  I'm from the PHP world. Recently I'm trying to learn about Java. Because simply I'm a bit interested in Android development. Learning about Java gives more control about my cellphone. Say I could fine tune some applications to fit my personal requirements or even make my own ones. Still Java is a new world to me. I guess I'm already too comfortable with weak typed languages such as PHP. Honestly I think application development of no matter which kind wouldn't make too much difference. Because just as web development mostly framework based, what the developer do is to fill the blanks meaning to follow the protocols the given by the framework. Most of the code is still about business logic, that's what application development all about, right? The big difference seems to lie on the programming languages. Comparing to PHP, Java holds a whole package of constraints and practices. At this point, what are the benefits to learn programming in it?

• Virtualbox: Raw linux partition not booting

  - by abalter

  I have a dual-boot laptop with Windows 7 and Ubuntu 12.04. I am trying to boot the ubuntu partition from windows using Virtualbox. I have successfully created the .vmdk, and created the virtual machine. However, I can't get it to boot (in Virtualbox). All I get is a black screen with the cursor in the top left. I wonder if I'm specifying the partitions correctly. My Ubuntu install has 3 partitions: \, \boot, \home. No swap partition. These are all in Disk 0, partitions 3,4,5 respectively. The command I used to create the .vmdk is: VBoxManage internalcommands createrawvmdk -filename C:\Users\abalter\.virtualbox\ubuntu.vmdk -rawdisk \\.\PhysicalDrive0 -partitions 3,4,5 Then I create a virtual machine based on that .vmdk. Why won't it boot?

• Developer with 4 years experience with Java/C++. How to move into web programming? [closed]

  - by JerryC

  Possible Duplicate: Tips for switching jobs and moving into web based programming? I graduated in 2006 with a computer science degree and got solid grades (3.5 overall 3.8 in my major) For the past 4.5 years I've been working as a Software Engineer doing primarily rich client development. Most of my experience is with Java, Swing and C++. I've done a lot of network programming and I have acquired some skill working & debugging in distributed environments. I would like to switch jobs and move into a role where I can get exposure to some new technologies and frameworks. I would like to move into a more web development role but I find my lack of web development experience is hurting me. 90% of the jobs I see advertised are looking for one of two skill sets: 1) Stereotypical server side Java web developer. Experience with Spring, Hibernate, J2EE, etc. 2) Stereotypical front end web developer. Experience with Javascript, jQuery, HTML5, GWT, CSS, etc I find most of these companies are looking really specifically for this experience and they are not willing to take on good programmers/ CS fundamental guys who lack experience with this stuff. I would love to get a job doing stuff like this, but have my skills become out of date and unmarketable? Any opinions on ways to sell myself to help get a new position?

• Copy only remaining rows after filter to new Excel Workbook

  - by Joel Coehoorn

  I have an Excel file with an external data connection set up. It pulls data in directly from a database, and gives us about 450 rows. The header row allows us to filter the data in the sheet, and we use this as a general purpose tool... I will use the filters to narrow down what I'm looking at based on criteria that change depending on the circumstance. Often, after filtering the data, I want to send just the filtered records to another person. I'd like to copy/paste just the remaining rows into a new Workbook to send via e-mail. Unfortunately, this doesn't work. When I paste the data, it still pastes all the data. The filtered rows are still in the workbook... they're just hidden. I want them gone from the new file completely. How can I do this?

• News Applications internal working [on hold]

  - by Vijay

  How does news applications work other than RSS Feed based applications? I know some of them take the RSS content from the source site.But sometimes I see, those applications show - Title Description Date Image video etc. Even though when I see the original site's rss, image, video is not there in rss. So how does one get that to show in there applications? Some applications even shows feeds from magazine sites, newspaper sites. How do these applications work? I am creating an application which will link to different news sites feeds categorized (like top news, technology, games, articles etc.) On the front page it will show the website names, then on selection of any news site it will get the feed from that website and show it to user. So I would like to know All the fetching of data from should be done on user selection or data should be prefetched? Detailed information I want to fetch from the original like provided in the rss data. How should I go about it?

• model association or controller?

  - by andybritton

  I'm trying to create a rails app that allows users to submit information about their pets. I've come to a point where my knowledge is limited and I don't know enough about what/how this could be done so I'm hoping this will be relatively easy to answer. At the moment I have a model called Pet, this model currently stores basic information like name, picture etc but it also holds more specific data like type, breed, date of birth etc. What I would like to be able to do is create a page that can match various records without having to be manually categorized if that makes sense so a users pet could be matched to other pets with the same breed, age etc. I've read about nested models as I understand this information could be submitted to 2 models in one form but I am not sure whether this could be done directly in a separate controller which would only be visible to users with pets in these matched "groups" if that makes sense. So in essence is it best practice to use 1 table to store all the information and just use a controller to match pets based on rows having the same values or would it be far simpler to have a form with a nested model and link 2 tables together? The main feature needs to be matching without a user having to create a group or categorize pets so the second model would need to add id's to an array instead of just creating more and more rows.

• Autohotkey + Windows 8.1 + WInKey shortcuts --> Causes the Start Screen to pop up

  - by user28417

  I have a AHK script with many shortcuts that I have been using for years now. Most of them are based on the winkey, for example: ; visual studio visualStudio = ahk_class wndclass_desked_gsk|Afx:400000:8:10011|SWT_Window0 GroupAdd ,visualStudioGroup ,%visualStudio% #q:: DetectHiddenWindows, %MyDetect% GroupActivate,visualStudioGroup,R Winshow return When I use these shortcuts, sometimes, but not always, the new Windows 8.1 start screen will popup and then I have to press the shortcut again to get back to the application I wanted to go to. I was wondering, Is this a known issue? Is there a way to fix it? Thanks in Advance.

• solr administration

  - by devrick0

  Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

• SQL Server 2005/2008 Licensing Decision

  - by Hakim

  Hello, I have purchased a dedicated server from a reputable Hosting company. They only have Windows Server 2008 OS installed on it and NO Sql server. Server Configuration is Intel Dual core Processor with 2GB of RAM and 100GB HDD. I wanted to host my web services on that server which will be using the MS SQL Server 2005 at the backend.There are multiple web services and each using a different Database. Microsoft has CAL basis Licensing , Which I understand is based on number of users accessing the database directly ( I may be wrong ) . But my users will be accessing the webservice and no direct connection to the database as such. Yes but the number of users accessing the web server cannot be known and is not under my control. Which Licensing is best suited for this kind of setup ? I don't need analysing and BI services right now ,but i may want to upgrade that in future may be. Any help will be appreciated. Thanks

• Changing location in Google Chrome when searching

  - by Alex

  I've recently moved to the Czech Republic from Scotland and I can't find a way to permanently stop Google from automatically defaulting back to google.cz all the time. I've checked to ensure that all my google accounts and cookie based settings (e.g. Advanced Search Options) are set to English but it's still clearly doing an IP address lookup and disregarding everything else. The default Search Engine for Google Chrome (and switches to google.cz automatically): {google:baseURL}search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s I've tried hardcoding it to: http://www.google.com/search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s this kind of works, but won't work for inline searching, i.e. I always have to press enter in order to get any results which is a bit annoying as I've gotten so used to AJAX style searching I can't have been the only one to get this issue? Any help is appreciated

• software to view logs on remote server

  - by Tarun

  I have configured syslog server on my linux machine like this Linux Machine (syslog client) -- Linux Machine (syslog server) I have configured it and its working properly. Now, the problem is I want to look at the logs located on remote server in a particular directory for example /var/log/host-ip/httpd.log. One way is that I use ssh for that and then see those logs using commands like tail etc. So is there any Browser based graphical utility which I can use on my machine in which I just give the remote folder location, ip-address etc. and the software shows me the logs present on that remote server. Thanks.

• TYPO3 unable to log in

  - by Agata

  Hi, My company prepared a new website based on typo3 (don't know the version but they started to prepare it in October 2011 so it's probably from that time. A couple of days ago I got my user name and password but I'm unable to log in (Itried withIE, Firefox and Chrome). Each time I try typo3 behaves like I'd be entering wrong user name orpassword (for sure I'm entering the right one, I also tried other user's data it ended up the same way). I use Windows 7 and Kaspersky Internet Security 9.0.0.736 - might their settings block typo3? I really don't know what to do and can't obtain help from the IT department (in head office in another country)... Thank you for any suggestions in advance.

• Getting the total number of processors a computer has (c#)

  Here is a code snippet for getting the total number of processors a computer has without using Environment.ProcessorCount.

• First-class help desk solution? [closed]

  - by Andy Gregory

  A help desk, for larger companies is a place for centralized help within an enterprise to help the users of their products and services.Therefore,to find the solution that best fits your business requirements, it is important to research, examine, and compare help desk software. As far as I know,Hesk is an free helpdesk software with some limited features while h2desk can provide the hosted solution. But for my small business,i just need a web based help desk software which can provide ticket management and knowledge base faq. We need unlimited staff support. Maybe a freeware help desk software can not meet our needs. So,we are willing to pay for effective helpdesk solution. But it should be low cost. We have gotten two choice: iKode Helpdesk Nethelpdesk Our helpdesk team are tend to iKode Helpdesk. Any other efficient first-class help desk solution to share?

• Is there a browser independet bookmarktool supporting tags, date and free comments?

  - by bernd_k

  I am looking for a tool, which helps me to organize my personal bookmarks. I want to be able to assign tags and free comments to a bookmark. I want to search my bookmarks by tags date of bookmarking pattern in title pattern in url It would be nice to be web based to enable sharing my bookmarks between different machines. But for it would be OK, if it works on a single machine as long as it has some import/export way to transfer the links to a new machine replacing the old. As browsers I'm using Firefox and ChromePlus. It would be nice, if the solution works with both browsers. With free comments, I mean additional remarks stored for a bookmark, which is not essential for searching.

• Facing difficulty with migrating from wordpress to Drupal

  - by rakibtg

  One of my blog was build of Wordpress but now i want to use Drupal as the CMS of my Blog. To do so I have deleted all the Wordpress files from my server and the Database and MySQL user which are associated with wordpress blog and uploaded the Drupal files in my server directory where the wordpress files were. But, when i have opened the blog it shows the Wordpress blog! though its been deleted and their should be the Drupal Installation interface. So, i have re-checked my server directories and database, there is not wordpress files and wp database all are deleted, there is only the drupal files, but when i go to the blog to install drupal there is still the Wordpress blog, I have checked the blog in many web browsers and there is not cache memory problem. My hosting server is linux based. can't understand what to do? Any idea? Thanks

• Is it safe/wise to run Drupal alongside bespoke business web apps in production?

  - by Vaze

  I'm interested to know the general community feeling about the safety of running Drupal alongside bespoke, business critial ASP.NET MVC apps on a production server. Previously my employer's Drupal based 'visitor website' was hosted as a managed service with a 3rd party. While the LoB sites were hosted in-house. That 3rd party is no longer available so I'm considering my options: Bring Drupal in-house Find another 3rd party My concern is that I have little experience with Drupal administration (and no experience securing it) and that the addition of PHP to my IIS server poses a security risk. Is there a best practice that I can follow in this situation?

• Client and Server game update speed

  - by user20686

  I am working on a simple two player networked asteroids game using XNA and the Lidgren networking library. For this set up I have a Lidgren server maintaining what I want to be the true state of the game, and the XNA game is the Lidgren client. The client sends key inputs to the server, and the server process the key inputs against game logic, sending back updates. (This seemed like a better idea then sending local positions to the server.) The client also processes the key inputs on its own, so as to not have any visible lag, and then interpolates between the local position and remote position. Based on what I have been reading this is the correct way to smooth out a networked game. The only thing I don’t get is what value to use as the time deltas. Currently every message the server sends it also sends a delta-time update with it, which is time between the last update. The client then saves this delta time to use for its local position updates, so they can be using roughly the same time deltas to calculate position updates. I know the XNA game update gets called 60 times a second, so I set my server to update the game state at the same speed. This will probably only work as long as the game is working on a fixed time step and will probably cause problems if I want to change that in the future. The server sends updates to clients on another thread, which runs at 10 updates per second to cut down on bandwidth. I do not see noticeable lag in movement and over time if no user input is received the local and remote positions converge on each other as they should. I am also not currently calculating for any latency as I am trying to go one step at a time. So my question is should the XNA client be using its current game time to update the local game state and not being using time deltas sent by the server? If I should be using the clients time delta between updates how do I keep it in-line with how fast the server is updating its game state?

• Free firewall for Windows Server 2003

  - by n00b_Admin

  We have a Windows Server 2003 R2 Machine here at work that I need to ensure is accessible only from specific set of IP Addresses. The Server is on a LAN and I am aware that one of the possible solutions maybe limit access to the Server's VLAN. However that is not feasible at the moment. I've been searching for a firewall that could do this, Windows' Firewall is pretty limited and I don't see an option in it to limit incoming data based on Source IP addresses. Most free firewalls like Comodo and ZoneAlarm don't work on Windows Server. Any ideas on how to accomplish this would be of great help. Thanks in advance.

• Can I control Caption sequence numbering from styles other than "Heading "?

  - by Carl Witthoft

  Similar question to Wrong caption using 'Appendix' header style , so the answer may well be "I can't." I created a style called "Appendix" which is based on "Heading 1" , is at "level 1" , and is numbered A,B,C... . I use the standard "Insert Caption" to get Figure or Table captions. I then modded the first field code to be STYLEREF "Appendix" \s and that properly displays the Appendix letter sequence. However, the second field code, SEQ \s 1 refers to the last "Heading 1" . I've tried things like SEQ \s "Appendix" to no avail. Is there any way around this? Should I generate a new "Appendix caption"-ish style which is a "numbered list" and manually set the 'restart at 1' counting in each Appendix?

• Apache resolves all URLs to default

  - by Ariel

  I am using Apache 2.2 on a Debian-based distro. For some reason, all URLs are directed to the default index. No error or anything. That means: example.domain.com goes to domain.com. "example" can be just anything. In the default Vhost file (/etc/apache2/sites-available/default) I've added: ServerName: www.domain.com But it still keeps that odd behaviour. Please let me know how to enable the common, default behaviour. I haven't changed anything by the way, this is since installation. Update: Following SvW's answer, I am looking for a way to force Apache not to accept any URL, only those specified as VirtualHosts.

• How can I do a bulk caller ID lookup (reverse phone lookup) on a list of phone numbers?

  - by rob

  I have a tab-delimited text file with all of the phone numbers I've called or received calls from in the past year. The phone numbers are all based in the US, so the format is ###-###-####. For tax purposes, I need to know which calls were personal and which ones were business-related. I could enter them all one-by-one into Google, but that will take forever because there are hundreds of numbers to check. Is there a program, MS Office plugin, or website that I can use to look up all of the numbers at once? If not, is there some way to create an Excel macro to do the lookups for me?

• Type of AI to tackle this problem?

  - by user1154277

  I posted this on stackoverflow but want to get your recommendations as well as a user on overflow recommended I post it here. I'm going to say from the beginning that I am not a programmer, I have a cursory knowledge of different types of AI and am just a businessman building a web app. Anyways, the web app I am investing in to develop is for a hobby of mine. There are many part manufacturers, product manufacturers, upgrade and addon manufacturers etc. for hardware/products in this hobby's industry. Currently, I am in the process of building a crowd sourced platform for people who are knowledgeable to go in and mark up compatibility between those parts as its not always clear cut if they are for example: Manufacturer A makes a "A" class product, and manufacturer B makes upgrade/part that generally goes with class "A" products, but is for one reason or another not compatible with Manufacturer A's particular "A" class product. However, a good chunk (60%-70%) of the products/parts in the database can have their compatibility inferenced by their properties, For example: Part 1 is type "A" with "X" mm receiver and part 2 is also Type "A" with "X" mm interface and thus the two parts are compatible.. or Part 1 is a 8mm gear, thus all bushings of 8mm from any manufacturer is compatible with part 1. Further more, all gears can only have compatibility relationships in the database with bushing and gear boxes, but there can be no meaningful compatibility between a gear and a rail, or receiver since those parts don't interface. Now what I want is an AI to be able to learn from the decisions of the crowdsourced platform community and be able to inference compatibility for new parts/products based on their tagged attributes, what type of part they are etc. What would be the best form of AI to tackle this? I was thinking a Expert System, but explicitly engineering all of the knowledge rules would be daunting because of the complex relations between literally tens of thousands of parts, hundreds of part types and many manufacturers. Would a ANN (neural network) be ideal to learn from the many inputs/decisions of the crowdsource platform users? Any help/input is much appreciated.

• Easy to use database with views for a medical student doing research?

  - by Sarah

  I'm having trouble finding a tool that does this for my friend (without designing it myself). What is needed is a simple program with a database where input forms and views can be designed and saved. A patient table might consist of, say, 50 columns, so it is imperative that it is possible to make columns be able to default, say, through a form for submission of data. By views I mean something like "saved selections" based on various criteria (WHERE runny_nose=True...) but as friendly as possible to save, and export options would be nice. Does this exist at all?
