• A Cost Effective Solution to Securing Retail Data

  - by MichaelM-Oracle

  By Mike Wion, Director, Security Solutions, Oracle Consulting Services As so many noticed last holiday season, data breaches, especially those at major retailers, are now a significant risk that requires advance preparation. The need to secure data at all access points is now driven by an expanding privacy and regulatory environment coupled with an increasingly dangerous world of hackers, insider threats, organized crime, and other groups intent on stealing valuable data.

• When does implementing MVVM not make sense

  - by Kelly Sommers

  I am a big fan of various patterns and enjoy learning new ones all the time however I think with all the evangelism around popular patterns and anti-patterns sometimes this causes blind adoption. I think most things have individual pros and cons and it's important to educate what the cons are and when it doesn't make sense to make a particular choice. The pros are constantly advocated. "It depends" I think applies most times but the industry does a poor job at communicating what it depends ON. Also many patterns surfaced from inheriting values from previous patterns or have derivatives, which each one brings another set of pros and cons to the table. The sooner we are more aware of the trade off's of decisions we make in software architecture the sooner we make better decisions. This is my first challenge to the community. Even if you are a big fan of said pattern, I challenge you to discover the cons and when you shouldn't use it. Define when MVVM (Model-View-ViewModel) may not make sense in a particular piece of software and based on what reasons. MVVM has a set of pros and cons. Let's try to define them. GO! :)

• How to efficiently protect part of an application with a license

  - by Patrick

  I am working on an application that has many functional parts. When a customer buys the application, he buys the standard functionality, but he can also buy some additional elements of the application for an additional price. All of the elements are part of the same application executable. A license key is used to indicate which of the elements should be accessible in the application. Some of the elements can be easily disabled if the user didn't pay for it. These are typically the modules that you can access via the application's menu. However, some elements give more problems: What if a part of the data model is related to an optional part? Do I build up these data structures in my application so the rest of my application can just assume they're always there? Or do I don't build them, and add checks in the rest of may application? What if some optional part is still useful to perform some internal tasks, but I don't want to expose it to the user externally? What if the marketing responsible wants to make a standard part now an optional part? In all of my application I assume that that part is present, but if it becomes optional, I should add checks on it everywhere in the application. I have some ideas on how to solve some of the problems (e.g. interfaces with dual implementations: one working implementation, and one that is activated if the optional part is not activated). Do you know of any patterns that can be used to solve this kind of problem? Or do you have any suggestions on how to handle this licensing problem? Thanks.

• Mocking concrete class - Not recommended

  - by Mik378

  I've just read an excerpt of "Growing Object-Oriented Software" book which explains some reasons why mocking concrete class is not recommended. Here some sample code of a unit-test for the MusicCentre class: public class MusicCentreTest { @Test public void startsCdPlayerAtTimeRequested() { final MutableTime scheduledTime = new MutableTime(); CdPlayer player = new CdPlayer() { @Override public void scheduleToStartAt(Time startTime) { scheduledTime.set(startTime); } } MusicCentre centre = new MusicCentre(player); centre.startMediaAt(LATER); assertEquals(LATER, scheduledTime.get()); } } And his first explanation: The problem with this approach is that it leaves the relationship between the objects implicit. I hope we've made clear by now that the intention of Test-Driven Development with Mock Objects is to discover relationships between objects. If I subclass, there's nothing in the domain code to make such a relationship visible, just methods on an object. This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I can't figure out exactly what he means when he says: This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I understand that the service corresponds to MusicCentre's method called startMediaAt. What does he mean by "elsewhere"? The complete excerpt is here: http://www.mockobjects.com/2007/04/test-smell-mocking-concrete-classes.html

• 11.10 liveCD black screen

  - by Shaun Killingbeck

  Attempting to install/try ubuntu 11.10 on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. I have caught a glimpse of some output to do with pulseaudio and [fail], but I can't imagine why that would cause a screen problem and the sound definitely works anyway.

• Need advice for approach for a web-based app that loads excel worksheet but exposes only the charts

  - by John

  I'm looking for suggestions on the Visual Studio approach to take for a web application that is in the conceptual stage. My environment has a lot of tools: Windows Server 2008 R2 Standard 64bit Visual Studio 2010 Professional Edition Sharepoint 2010 Server Enterprise Edition SQL Server 2008 R2 Office 2010 Professional I know I will need this app to retrieve data from a database (or a web service - not sure exactly at this point). The data needs to be placed in an Excel workbook dynamically. The app will need to have a nice user interface (standard web controls - perhaps with some Javascript effects). The Excel ribbon and worksheet grid will need to be hidden. Some web control(s) will cause the Excel chart(s) to be rendered. I am thinking this sounds like Visual Studio Tools for Office (VSTO) so as to leverage .Net and hide Excel. Can you offer suggestions regarding: One ASP.Net Web App Project One Class Library Project for Excel or perhaps which one of the several different Excel 2010 project types (addin, template, document) Would Excel Services for Sharepoint be useful (or required) ? I am feeling a little overwhelmed with so many choices at this early stage of conceptualizing the app. Can you suggest some ideas for this sort of thing? Also, I am a bit more experienced with C# but I've read VB.Net is better for work with the Excel object model. What are general advises with regard to tool choice and overall approach tradeoffs?

• Help with dual booting Windows 8.1 Professional and Ubuntu 13.10

  - by user1292548

  I recently installed a clean version of Windows 8.1 Professional on my Lenovo Y500 (with Samsung 256GB 840 Pro SSD). I have Windows all set up and running normally. I am trying to dual boot Windows 8.1 and Ubuntu 13.10, but the installation procedure don't allow me to either "Install alongside..." or shows my SSD partitions correctly when I chose the "Something Else" option. I have created a 25GB partition of free space in the Windows disk manager, but on the installation screen on Ubuntu, it shows the whole drive as a free space. I have tried installing with a burned .ISO disk and a bootable USB, the results are the same for both. Windows Disk Management screen: http://imageshack.us/a/img855/9504/59zu.jpg The Ubuntu installation screen: http://imageshack.us/a/img62/2712/9g6i.jpg I've ran into this problem before when trying to dual boot Ubuntu and Windows 7 Professional a month ago. But I gave up and never resolved the issue. --EDIT-- I tried what Eero Aaltonen suggested, and this is my result: ubuntu@ubuntu:~$ sudo parted /dev/sda print Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? yes Model: ATA Samsung SSD 840 (scsi) Disk /dev/sda: 256GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags ubuntu@ubuntu:~$

• Tools for game script / storyboard

  - by Pietro Polsinelli

  I am searching for a tool that will help in writing a game script. By "script" I mean the text core of a storyboard - without the drawing drafts, which may or may not be there (yet). What I'm thinking of will let write a piece of text of the script, define a simplified workflow from that step, and then define the text of next steps, and so on. Searching online, I found Inform http://inform7.com/ ("A Design System for Interactive Fiction Based on Natural Language") which in theory is exactly what I am searching for, but trying to use it it has this model of a space (a dungeon, a library) where you are picking up objects and exploring them. In my case I am designing more a Sims like game, the flow is entirely different. Considering non specific software, mind mapping tools miss the linearity of the process. What I am writing is a directed graph - simply a work-flow, but the way I want to design it is more text based than work-flow based. SO what I'm doing now is using a text editor, which I'll transform directly in code. Any suggestions?

• Two graphical entities, smooth blending between them (e.g. asphalt and grass)

  - by Gabriel Conrad

  Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

• What to learn to make a photo gallery site like this? [closed]

  - by Steven Chen

  I started a Wordpress site for my blog but now I want to start another domain for sharing my photos. I used to use Flickr but it requires you to sign up for Flickr Pro if you want to upload over a certain amount of photos. Since I don't want to pay for that, I'm looking to create a photo gallery site like this: http://10mmgalore.com/ or http://www.shuttermaki.com/ But how do you go about with that? Would I be able to install Wordpress and find a theme like that? And/Or are there any Wordpress plugins that I can install to make it like look like that? Or do I need different tools and platforms asides from Wordpress? So can someone list the features, tools and information that I need to make a photo gallery site? The main functions that I want for my site is to have a picture in the middle and when the user clicks on the photo, it goes to the next photo; or there are left and right arrows that users can click to the next photo. I just want to create an album website for my 365 days project (a photo a day). It doesn't have to be as fancy as the sites mentioned above. Thank you!

• Does unit testing lead to premature generalization (specifically in the context of C++)?

  - by Martin

  Preliminary notes I'll not go into the distinction of the different kinds of test there are, there are already a few questions on these sites regarding that. I'll take what's there and that says: unit testing in the sense of "testing the smallest isolatable unit of an application" from which this question actually derives The isolation problem What is the smallest isolatable unit of a program. Well, as I see it, it (highly?) depends on what language you are coding in. Micheal Feathers talks about the concept of a seam: [WEwLC, p31] A seam is a place where you can alter behavior in your program without editing in that place. And without going into the details, I understand a seam -- in the context of unit testing -- to be a place in a program where your "test" can interface with your "unit". Examples Unit test -- especially in C++ -- require from the code under test to add more seams that would be strictly called for for a given problem. Example: Adding a virtual interface where non-virtual implementation would have been sufficient Splitting -- generalizing(?) -- a (smallish) class further "just" to facilitate adding a test. Splitting a single-executable project into seemingly "independent" libs, "just" to facilitate compiling them independently for the tests. The question I'll try a few versions that hopefully ask about the same point: Is the way that Unit Tests require one to structure an application's code "only" beneficial for the unit tests or is it actually beneficial to the applications structure. Is the generalization code need to exhibit to be unit-testable useful for anything but the unit tests? Does adding unit tests force one to generalize unnecessarily? Is the shape unit tests force on code "always" also a good shape for the code in general as seen from the problem domain? I remember a rule of thumb that said don't generalize until you need to / until there's a second place that uses the code. With Unit Tests, there's always a second place that uses the code -- namely the unit test. So is this reason enough to generalize?

• best way to host multiple wordpress site on single vps [migrated]

  - by Ben

  Not sure if this is webmaster or a WordPress question, it's a bit half and half, sorry if I'm posting in the wrong place. Without using Multi-Site or installing new WordPress CMS' in second-level domains, what's the best way to get multiple WordPress installs running on my VPS (running Linux powered CentOS 6 with WHM and cPanel)? It's currently working but only by setting the permalinks option to the default setting, so the URLs aren't human-friendly. I have come across something called WPSiteStack, though I'd really rather not go down this route. Long story short, I need the following: Seperate installs so one core / theme / plugin update doesn't affect all sites and increases security of all sites; 'Pretty' permalinks; Each WordPress install must be in the root of it's own domain to ensure that I can accurately measure my clients' quotas; It may also be worth noting that some functions within each install use the $_SERVER['DOCUMENT_ROOT'] and $_SERVER['HOST'] variables. I have already edited the httpd-vhosts.conf, httpd.conf and .htaccess files but this hasn't made any changes. So any ideas what I'm missing or doing wrong? Any help is much appreciated.

• How to implment the database for event conditions and item bonuses for a browser based game

  - by Saifis

  I am currently creating a browser based game, and was wondering what was the standard approach in making diverse conditions and status bonuses database wise. Currently considering two cases. Event Conditions Needs min 1000 gold Needs min Lv 10 Needs certain item. Needs fulfillment of another event Status Bonus Reduces damage by 20% +100 attack points Deflects certain type of attack I wish to be able to continually change these parameters during the process of production and operation, so having them hard-coded isn't the best way. All I could come up with are the following two methods. Method 1 Create a table that contains each conditions with needed attributes Have a model named conditions with all the attributes it would need to set them conditions condition_type (level, money_min, money_max item, event_aquired) condition_amount prerequisite_condition_id prerequisite_item_id Method 2 write it in a DSL form that could be interpreted later in the code Perhaps something like yaml, have a text area in the setting form and have the code interpret it. condition_foo: condition_type :level min_level: 10 condition_type :item item_id: 2 At current Method 2 looks to be more practical and flexible for future changes, trade off being that all the flex must be done on the code side. Not to sure how this is supposed to be done, is it supposed to be hard coded? separate config file? Any help would be appreciated. Added For additional info, it will be implemented with Ruby on Rails

• Why would Java app make RPC call to itself?

  - by amphibient

  I am working with a multithreaded homegrown multi-module app in my new job. We use the the Thrift protocol to communicate RPC calls between different stand-alone applications in a distributed system. One of them listens on multiple ports and I just noticed that it actually makes an RPC call to itself from one thread invoked from one socket it listens to (web service call) to another port within the same app. I verified that it could accomplish the same thing if it just went and directly called the method that the remote procedure ultimately invokes as it is all within the same application, same JVM. To make it even more mysterious, the call is completely synchronous, i.e. no callbacks involved. The first thread totally sits and waits until it makes a call across the wire to itself and comes back. Now, I am perplexed why anybody would do it this way. It seems like calling somebody on the phone that sits in the same room as you do. Can anybody provide an explanation why the developer before me would come up with the above mentioned model? Maybe there is a reason and I am missing something.

• Is it wise for a programmer to move into management?

  - by Desolate Planet

  Many times, a developer has suggested that I become a team leader because I'm motivated, but during my career in the IT industry, I've seen so many people who are great at programming, move into management and they are miserable. I've also seen many managers return to programming stating "I'm a technical person, I like technical problems". If this is such a common thing, why do developers feel compelled to leave the technical domain and move into management? Sure you'll have more money and more control, but if you don't enjoy your work and take your problems out on your tream. Secondly, I've been asked in developer interviews, "Would you consider leading a team?" and I'm always tempted to cite the Peter Principle based on what I've seen. I am interested in furthering myself, but not in the way the company may want i.e "Vice President of department blah". To be honest, I've seen this more often in the corporate world than in small development houses and it's always put me off ever going back to a corporate environment. I just feel that this is becoming more and more the norm and it's impacting team morale and degrading the quality of the work. Question: Based on what I've said, Is it a smart move for a technical person to move into management?

Various instructions on the internet have helped the student to do the following Installation of dhcp server and hostapd: sudo apt-get install isc-dhcp-server sudo apt-get install hostapd File: /etc/network/interfaces auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 10.10.0.1 netmask 255.255.255.0 dns-nameservers 172.31.1.1 172.31.1.2 File: /etc/dhcp/dhcpd.conf subnet 10.10.0.0 netmask 255.255.255.0 { range 10.10.0.2 10.10.0.4; option routers 10.10.0.1; option domain-name-servers 172.31.1.1 172.31.1.2; default-lease-time 6000; max-lease-time 72000; } File: /etc/hostapd/hostapd.conf interface=wlan0 driver=nl80211 ssid=my_hotspot channel=1 hw_mode=g auth_algs=1 wpa=3 wpa_passphrase=1234567890 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP CCMP rsn_pairwise=CCMP File: /etc/default/hostapd RUN_DAEMON=”yes” DAEMON_CONF=”/etc/hostapd/hostapd.conf” DAEMON_OPTS=”-dd” File: /etc/default/isc-dhcp-server INTERFACES=”wlan0” File: /etc/rc.local iptables -t nat -A POSTROUTING -s 10.10.0.0/16 -o eth0 -j MASQUERADE exit 0 After all the configuration, the computer is restarted. The student can see that the hotspot named “my_hotspot” is available. The hotspot also awards an address to the android phone. The student will now be able to browse the internet.

• ArchBeat Link-o-Rama for 2012-09-25

  - by Bob Rhubart

  Oracle 11gR2 RAC on Software Defined Network (SDN) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. ServerSent-Events on WebLogic Server | Steve Buttons "The HTML5 ServerSent-Event model provides a mechanism to allow browser clients to establish a uni-directional communication path to a server, where the server is then able to push messages to the browser at any point in time," explains Steve "Buttso" Buttons. Focus on Architects and Architecture This handy guide for sessions and other activities at Oracle OpenWorld 2012 focuses on IT architecture in all its many facets and permutations. Operating System Set-up for WebLogic Server | Rene van Wijk Oracle ACE Rene van Wijk shows you how to set-up an operating system for WebLogic Server.

• What are some efficient ways to set up my environment when working on a remote site?

  - by Prefix

  Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

• Are webhosts that require NS instead of a CNAME common?

  - by billpg

  I've just signed up with a webhost (which I prefer not to name) and I'm reasonably happy with it. The only nit was when I was ready to put a site online and I asked the support line to what name I should point my 'www' CNAME to. They responded that they don't do that and I need to set my domain's NS records for the hosting to work. "Why would you ever want to do it that way? Our service to you includes DNS and our servers are probably much better than the one your registrar provides." This was a bit of surprise as all of the other webhosts I've worked with happily support this. I've set up (eg) gallery.myfriend.example for friends by having them configure their DNS to CNAME 'gallery' to the name of a shared server at a webhost and the webhost does name-based hosting for 'gallery.myfriend.example'. (Of course, if the webhost ever tells me I'm being moved from A.webhost.example to B.webhost.example, it would be my responsibility to change where the CNAME points. Really good webhosts would instead create myname.webhost.example for the IP of whichever server my stuff happens to be on, so I'd never have to worry about keeping my CNAME up to date.) Is my impression correct, that most webhosts will happily support a service that begins with a CNAME hosted elsewhere, or is it really more common that webhosts will only provide a service if they control the DNS service too?

• The Enterprise Side of JavaFX: Part Two

  - by Janice J. Heiss

  A new article, part of a three-part series, now up on the front page of otn/java, by Java Champion Adam Bien, titled “The Enterprise Side of JavaFX,” shows developers how to implement the LightView UI dashboard with JavaFX 2. Bien explains that “the RESTful back end of the LightView application comes with a rudimentary HTML page that is used to start/stop the monitoring service, set the snapshot interval, and activate/deactivate the GlassFish monitoring capabilities.”He explains that “the configuration view implemented in the org.lightview.view.Browser component is needed only to start or stop the monitoring process or set the monitoring interval.”Bien concludes his article with a general summary of the principles applied:“JavaFX encourages encapsulation without forcing you to build models for each visual component. With the availability of bindable properties, the boundary between the view and the model can be reduced to an expressive set of bindable properties. Wrapping JavaFX components with ordinary Java classes further reduces the complexity. Instead of dealing with low-level JavaFX mechanics all the time, you can build simple components and break down the complexity of the presentation logic into understandable pieces. CSS skinning further helps with the separation of the code that is needed for the implementation of the presentation logic and the visual appearance of the application on the screen. You can adjust significant portions of an application's look and feel directly in CSS files without touching the actual source code.”Check out the article here.

• Routing tables don't show ppp0 after 12.04 kernel upgrade to 3.5.0: Haier CE682 modem configuration

  - by ubunsteve

  I'm trying to get my Haier CE682 EVDO modem, model number 201e:1022 to work in ubuntu 12.04 kernel 3.5.0-030500-generic #201207211835 . I had it working in a previous 12.04 kernel, using compat-wireless and these instructions http://zulkhamsyahmh.blogspot.com/2012/05/install-smartfren-haier-ce682-on-ubuntu.html, and to get it working had to edit the routing tables so that there was a ppp0 showing up, as suggested at http://www.linuxquestions.org/questions/slackware-14/wvdial-is-connecting-but-im-unable-to-do-anything-714861/ Network manager doesn't work with this modem, so I use either wvdial or gpppon to connect to it, both which work (after I run the command sudo modprobe usbserial vendor=0x201e product=0x1022 ) This is the output of when I connect with gpppon to the modem: Using interface ppp0 Connect: ppp0 <-- /dev/ttyUSB0 sent [LCP ConfReq id=0x1 ] rcvd [LCP ConfAck id=0x1 ] rcvd [LCP ConfReq id=0x2 ] sent [LCP ConfAck id=0x2 ] sent [LCP EchoReq id=0x0 magic=0x819c86db] rcvd [CHAP Challenge id=0x1 <1ac8f12799e953967a3cc222c9254690, name = ""] sent [CHAP Response id=0x1 <6f12a903dc40915ca2761c17b87f8fbd, name = "smart"] rcvd [LCP EchoRep id=0x0 magic=0x0] rcvd [CHAP Success id=0x1 ""] CHAP authentication succeeded CHAP authentication succeeded sent [CCP ConfReq id=0x1 ] sent [IPCP ConfReq id=0x1 ] rcvd [IPCP ConfReq id=0x1 ] sent [IPCP ConfAck id=0x1 ] rcvd [CCP ConfReq id=0x1] sent [CCP ConfAck id=0x1] rcvd [CCP ConfRej id=0x1 ] sent [CCP ConfReq id=0x2] rcvd [IPCP ConfRej id=0x1 ] sent [IPCP ConfReq id=0x2 ] rcvd [CCP ConfAck id=0x2] rcvd [IPCP ConfNak id=0x2 ] sent [IPCP ConfReq id=0x3 ] rcvd [IPCP ConfAck id=0x3 ] not replacing existing default route via 192.168.3.1 local IP address 10.191.248.154 remote IP address 10.17.95.25 primary DNS address 10.17.3.244 secondary DNS address 10.17.3.245 as you can see there is a problem with "not replacing existing default route via 192.168.3.1" This it the out put of route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.3.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.3.0 * 255.255.255.0 U 2 0 0 wlan0 I had tried these commands, which had previously worked in the earlier kernel: route del default route add default ppp0 but that broke my wireless internet connection. I then added the default routing as shown above with sudo route add default gw 192.168.3.1 wlan0 So it seems I need to add or change the routing to show a ppp0 connection, but I don't know how to do that.

• Will search engines discover that our old pages have been 301 redirected if there are no more links to them in the old site?

  - by Obay

  We've moved our website to a new domain. Thousands of our pages come from one PHP file in the old site (e.g. oldsite.com/news.php?id=<id>). So we added some code in news.php file to do a 301 redirect to the specific corresponding news article in the new website (newsite.com/news/<id>). We have not yet done a 301 redirect for the root of the old site (so we could display a notice to our users that we've moved), but all links inside it are already 301 redirected. My concern is that, when Google crawls our old website, it will no longer be able to find the old news articles and discover that they have been 301 Redirected -- is this correct? If so, does that mean our PageRank won't be carried over to the new site? I've also read that we would need to create a sitemap for the new site. Is it possible to indicate in the sitemap the old and new locations of specific pages? Because if not, how will Google know? (I'm not sure change of address in Webmaster Tools would be specific enough).

• Using Clojure instead of Python for scalability (multi core) reasons, good idea?

  - by Vandell

  After reading http://clojure.org/rationale and other performance comparisons between Clojure and many languages, I started to think that apart from ease of use, I shouldn't be coding in Python anymore, but in Clojure instead. Actually, I began to fill irresponsisble for not learning clojure seeing it's benefits. Does it make sense? Can't I make really efficient use of all cores using a more imperative language like Python, than a lisp dialect or other functional language? It seems that all the benefits of it come from using immutable data, can't I do just that in Python and have all the benefits? I once started to learn some Common Lisp, read and done almost all exercices from a book I borrowod from my university library (I found it to be pretty good, despite it's low popularity on Amazon). But, after a while, I got myself struggling to much to do some simple things. I think there's somethings that are more imperative in their nature, that makes it difficult to model those thins in a functional way, I guess. The thing is, is Python as powerful as Clojure for building applications that takes advantages of this new multi core future? Note that I don't think that using semaphores, lock mechanisms or other similar concurrency mechanism are good alternatives to Clojure 'automatic' parallelization.

• Ubuntu 12.04 Freezes at Bootup

  - by Ryan Yu

  I have an Acer Aspire One Model AO722, that has a dual-boot configuration with Windows 7 Home Premium and Ubuntu 12.04. Processor: AMD C-50, 1.00GHz 2.00GB ram, 64-bit, AMD Radeon HD 6250 Graphics. I installed Ubuntu two days ago, and since then, loading it has been sporadic. Windows 7 still loads just fine, but Ubuntu will sometimes freeze. First time I booted Ubuntu up, it ran no problem. Worked with it for half an hour, then shut down the computer. The second time I booted it up, it froze after ten minutes when I was trying to set up Thunderbird. Third time, same thing. Fourth time, it froze about 5 minutes after bootup when I was trying to connect to my wifi. Fifth time, it ran no problems for about 5~ hours. Then, three consecutive times I've restarted (what is it, the 6th, 7th, and 8th times?) it has gotten to the login screen, I've entered my password, all the text on the page disappears as if its going to load my desktop, and it freezes. A minute ago when I booted Ubuntu up for the 9th time, it loaded the desktop fine. Who knows if it'll crash soon; probably, though. Any ideas?
