• Why googling by keycaptcha gives results on reCAPTCHA? [closed]

  - by vgv8

  EDIT: I'd like to change this title to: How to STOP Google's manipulation of Google search engine presented to general public? I am frequently googling and more and more frequently bump when searching by one software product I am given instead the results on Google's own products. For ex., if I google by keyword keycaptcha for the "Past 24 hours" (after clicking on "Show search tools" -- "Past 24 hours" on the left sidebar of a browser) I am getting the Google's search results show only results on reCAPTCHA. Image uploaded later: Though, if confine keycaptcha in quotes the results are "correct" (well, kind of since they are still distorted in comparison with other search engines). I checked this during few months from different domains at different ISPs, different operating systems and from a dozen of browsers. The results are the same. Why is it and how can it be possibly corrected? My related posts: "How Gmail spam filter works?" IP adresses blacklisting Update: It is impossible for me to directly start using google.com as I am always redirected to google.ru (from google.com) by my ip-address "auto-detect location" google's "convenience". The google's help tells that it is impossible to switch off my location auto-detection because it is very helpful feature. There is a work-around to use google.com/ncr (to get google.com) (?anybody know what does it mean) to prevent redirection from google.com but even. But all results are exactly the same OK, I can search by quoted "keycaptcha", I am already accustomed to these google's quirks, but the question arises why the heck to burn time promoting someone's product if GOOGLE uses other product brands for showing its own interests/brands (reCAPTCHA) instead and what can be done with it? The general user will not understand that he was cheated and just will pick up the first (wrong) results Update2: Note that this googling behaviour: is independent on whether I am logged-in (or log-out-ed of) a google account, which account, on browser (I tried Opera, Chrome, FireFox, IE of different versions, Safari), OS or even domain; there are many such cases but I just targeted one concrete restricted example speciffically to to prevent wandering between unrelated details and peculiarities; @Michael, first it is not true and this text contains 2 links for real and significant results.. I also wrote that this is just one concrete example from many and based on many-month exp. These distortions happen upon clicking on: Past 24 hours, Past week, Past month, Past year in many other keywords, occasions/configurations of searches, etc. Second, the absence of the results is the result and there is no point to sneakingly substitute it by another unsolicited one. It is the definition of spam and scam. 3d, the question is not abt workarounds like how to write search queries or use another searching engines. The question is how to straighten the googling's results in order to stop disorienting general public about. Update: I could not understand: nobody reproduces the described by me behavior (i.e. when I click "Past 24 hours" link in google search searching for keycaptcha, the presented results are only on reCAPTCHA presented)? Update: And for the "Past week":

• Too complex/too many objects?

  - by Mike Fairhurst

  I know that this will be a difficult question to answer without context, but hopefully there are at least some good guidelines to share on this. The questions are at the bottom if you want to skip the details. Most are about OOP in general. Begin context. I am a jr dev on a PHP application, and in general the devs I work with consider themselves to use many more OO concepts than most PHP devs. Still, in my research on clean code I have read about so many ways of using OO features to make code flexible, powerful, expressive, testable, etc. that is just plain not in use here. The current strongly OO API that I've proposed is being called too complex, even though it is trivial to implement. The problem I'm solving is that our permission checks are done via a message object (my API, they wanted to use arrays of constants) and the message object does not hold the validation object accountable for checking all provided data. Metaphorically, if your perm containing 'allowable' and 'rare but disallowed' is sent into a validator, the validator may not know to look for 'rare but disallowed', but approve 'allowable', which will actually approve the whole perm check. We have like 11 validators, too many to easily track at such minute detail. So I proposed an AtomicPermission class. To fix the previous example, the perm would instead contain two atomic permissions, one wrapping 'allowable' and the other wrapping 'rare but disallowed'. Where previously the validator would say 'the check is OK because it contains allowable,' now it would instead say '"allowable" is ok', at which point the check ends...and the check fails, because 'rare but disallowed' was not specifically okay-ed. The implementation is just 4 trivial objects, and rewriting a 10 line function into a 15 line function. abstract class PermissionAtom { public function allow(); // maybe deny() as well public function wasAllowed(); } class PermissionField extends PermissionAtom { public function getName(); public function getValue(); } class PermissionIdentifier extends PermissionAtom { public function getIdentifier(); } class PermissionAction extends PermissionAtom { public function getType(); } They say that this is 'not going to get us anything important' and it is 'too complex' and 'will be difficult for new developers to pick up.' I respectfully disagree, and there I end my context to begin the broader questions. So the question is about my OOP, are there any guidelines I should know: is this too complicated/too much OOP? Not that I expect to get more than 'it depends, I'd have to see if...' when is OO abstraction too much? when is OO abstraction too little? how can I determine when I am overthinking a problem vs fixing one? how can I determine when I am adding bad code to a bad project? how can I pitch these APIs? I feel the other devs would just rather say 'its too complicated' than ask 'can you explain it?' whenever I suggest a new class.

• How to properly add .NET assemblies to Powershell session?

  - by amandion

  I have a .NET assembly (a dll) which is an API to backup software we use here. It contains some properties and methods I would like to take advantage of in my Powershell script(s). However, I am running into a lot of issues with first loading the assembly, then using any of the types once the assembly is loaded. The complete file path is: C:\rnd\CloudBerry.Backup.API.dll In Powershell I use: $dllpath = "C:\rnd\CloudBerry.Backup.API.dll" Add-Type -Path $dllpath I get the error below: Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. At line:1 char:9 + Add-Type <<<< -Path $dllpath + CategoryInfo : NotSpecified: (:) [Add-Type], ReflectionTypeLoadException + FullyQualifiedErrorId : System.Reflection.ReflectionTypeLoadException,Microsoft.PowerShell.Commands.AddTypeComma ndAdd-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. Using the same cmdlet on another .NET assembly, DotNetZip, which has examples of using the same functionality on the site also does not work for me. I eventually find that I am seemingly able to load the assembly using reflection: [System.Reflection.Assembly]::LoadFrom($dllpath) Although I don't understand the difference between the methods Load, LoadFrom, or LoadFile that last method seems to work. However, I still seem to be unable to create instances or use objects. Each time I try, I get errors that describe that Powershell is unable to find any of the public types. I know the classes are there: $asm = [System.Reflection.Assembly]::LoadFrom($dllpath) $cbbtypes = $asm.GetExportedTypes() $cbbtypes | Get-Member -Static ---- start of excerpt ---- TypeName: CloudBerryLab.Backup.API.BackupProvider Name MemberType Definition ---- ---------- ---------- PlanChanged Event System.EventHandler`1[CloudBerryLab.Backup.API.Utils.ChangedEventArgs] PlanChanged(Sy...

• Cannot run a VM with more than three network interfaces with KVM

  - by Bostonvaulter

  I'm running KVM on top of Ubuntu 10.10 Server I can create VM's (Virtual Machine) and network interfaces fine but I cannot seem to add more than three network interfaces. As soon as I have a VM with four network interfaces it gets stuck on startup at the starting SeaBIOS page with this message: Starting SeaBIOS (version pre-0.6.1-20100702_143500-palmer) So far I've verified this with two VM's, a Ubuntu 10.10 desktop and a Vyatta router. The specific network hardware I assign to the VM's doesn't seem to matter. I'm trying to have one bridged interface and three private networks using Vyatta to route between them. Does anyone know why I can't run a VM with more than three network interfaces? Edit: Additionally the KVM thread responsible for the specific VM hangs using ~100% CPU (i.e. one core). Here's the command for the process that is hanging: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name vyatta -uuid 6dff7c94-6810-423e-5fea-fec10da0e9b7 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/vyatta.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot c -drive file=/home/rams/virtual-machines/vyatta.img,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device rtl8139,vlan=0,id=net0,mac=00:54:00:be:cc:4b,bus=pci.0,addr=0x3 -net tap,fd=97,vlan=0,name=hostnet0 -device rtl8139,vlan=1,id=net1,mac=52:54:00:da:59:ed,bus=pci.0,addr=0x5 -net tap,fd=98,vlan=1,name=hostnet1 -device rtl8139,vlan=2,id=net2,mac=52:54:00:ce:22:b6,bus=pci.0,addr=0x6 -net tap,fd=99,vlan=2,name=hostnet2 -device rtl8139,vlan=3,id=net3,mac=52:54:00:1e:bc:46,bus=pci.0,addr=0x7 -net tap,fd=101,vlan=3,name=hostnet3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 Edit: I've also found an error in dmesg that might be related (it also shows up when running virtd in verbose mode): 14:47:24.399: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed I've also tried disabling app armor but that doesn't seem to make a difference.

• Cliq Wireless questions

  - by Nathan Adams

  Heres the deal: I am by no means a Linux expert, even less when it comes to the Android OS but lets see if we can't solve this problem. The problem I am having is that on the Cliq we have a broadcom chip. In order to use the wireless card you must first insert the module into the kernel. Fine: # insmod /system/lib/dhd.ko insmod /system/lib/dhd.ko # lsmod lsmod dhd 164936 0 - Live 0xbf000000 # BUT netcfg (or ifconfig in busybox) does not recognize that there is a wireless adapter there: # netcfg netcfg lo UP 127.0.0.1 255.0.0.0 0x00000049 dummy0 DOWN 0.0.0.0 0.0.0.0 0x00000082 rmnet0 UP 14.67.164.2 255.255.255.252 0x00001043 rmnet1 DOWN 0.0.0.0 0.0.0.0 0x00001002 rmnet2 DOWN 0.0.0.0 0.0.0.0 0x00001002 usb0 DOWN 0.0.0.0 0.0.0.0 0x00001002 # busybox ifconfig busybox ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:282 errors:0 dropped:0 overruns:0 frame:0 TX packets:282 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18754 (18.3 KiB) TX bytes:18754 (18.3 KiB) rmnet0 Link encap:Ethernet HWaddr EE:83:E8:B4:4A:ED inet addr:14.x.x.x Bcast:14.67.164.3 Mask:255.255.255.252 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7148 errors:0 dropped:0 overruns:0 frame:0 TX packets:7659 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2609236 (2.4 MiB) TX bytes:908575 (887.2 KiB) # For giggles if we attempt to launch wpa_supplicant anyways we get this: # wpa_supplicant -Dwext -ieth0 -c/data/misc/wifi/wpa_supplicant.conf wpa_supplicant -Dwext -ieth0 -c/data/misc/wifi/wpa_supplicant.conf ioctl[SIOCSIWPMKSA]: No such device ioctl[SIOCSIWMODE]: No such device Could not configure driver to use managed mode ioctl[SIOCGIFFLAGS]: No such device Could not set interface 'eth0' UP ioctl[SIOCGIWRANGE]: No such device ioctl[SIOCGIFINDEX]: No such device CTRL-EVENT-STATE-CHANGE id=-1 state=0 ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWAUTH]: No such device WEXT auth param 7 value 0x0 - Failed to disable WPA in the driver. ioctl[SIOCSIWAUTH]: No such device WEXT auth param 5 value 0x0 - ioctl[SIOCSIWAUTH]: No such device WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAP]: No such device ioctl[SIOCGIFFLAGS]: No such device # In dmesg we get: <4>[18300.494065] dhd_oob_enable_intr : enable <4>[18305.019976] dhd_net_start failed bus is not ready <4>[18305.020278] dhdsdio_probe: dhd_net_start failed! Do I need to specify the firmware with insmod? Why are we trying to control the interface manually instead of through the Android API? The Android API doesn't support ad-hoc connections as far as I can tell. The card, I am sure, most certainly can.

• Snmpd update interface counters slowly or something like this

  - by Korjavin Ivan

  I update one my freebsd box to 9-stable (totally new installation) and install net-snmp for monitoring. uname -r 9.1-PRERELEASE pkg_info net-snmp-5.7.1_7 Information for net-snmp-5.7.1_7: Comment: An extendable SNMP implementation .... cat /var/db/ports/net-snmp/options # This file is auto-generated by 'make config'. # Options for net-snmp-5.7.1_7 _OPTIONS_READ=net-snmp-5.7.1_7 _FILE_COMPLETE_OPTIONS_LIST= IPV6 MFD_REWRITES PERL PERL_EMBEDDED PYTHON DUMMY TKMIB DMALLOC MYSQL AX_SOCKONLY UNPRIVILEGED OPTIONS_FILE_UNSET+=IPV6 OPTIONS_FILE_UNSET+=MFD_REWRITES OPTIONS_FILE_SET+=PERL OPTIONS_FILE_SET+=PERL_EMBEDDED OPTIONS_FILE_UNSET+=PYTHON OPTIONS_FILE_SET+=DUMMY OPTIONS_FILE_UNSET+=TKMIB OPTIONS_FILE_SET+=DMALLOC OPTIONS_FILE_UNSET+=MYSQL OPTIONS_FILE_UNSET+=AX_SOCKONLY OPTIONS_FILE_UNSET+=UNPRIVILEGED I have about 500 vlan on this machine, and collect info about interface through snmpd to 2 different software, zabbix and cacti. And both of them plot the graphs with blank fields. I tryed change polling time in zabbix, from 15, sec to 30,60,90,120,10. And anyway i have blank fields. snmpd.conf is empty - only a access controls. This configuration worked fine on freebsd 8. Where is my fault? How fix this graphs? UPD: Changing pooling time, switch off one of agent, doesnt help. I look at zabbix log (recieved data from snmpd) and see that: sorry for russian locale, just look at numbers: and thats is not true, as my "iftop" show speed was about 90Mbits, but snmpd return 2Mbits. I understand that snmpd doesnt return speed, it return just a counter. But how its possible? why 2Mbit/s ? I tryed recompile snmpd with 64-bit counters, and without it. In both variants this blank fields present. So i think its my OS (freebsd) doesnt update interface counters well. I still collect tcpdump for found this request/response. But have problem with that, to much trash. UPD2: I decrypt tcpdump-ed file, and public this as google doc at gdocfile Timediff looks strange.. Like zabbix sometimes "forget" do request, and then do twice at row, ehh UPD3: I parse log from command "while true; do netstat -bin -I vlan4008 /var/log/netstat; sleep 300; done" and load as google docs, and add formula for speed : link Looks like all counters in OS are good. Now i think problem in : 1. zabbix get request twice at row (and what about cacti) 2. snmpd use counter32

• Session Report: What’s New in JSF: A Complete Tour of JSF 2.2

  - by Janice J. Heiss

  On Wednesday, Ed Burns, Consulting Staff Member at Oracle, presented a session, CON3870 -- “What’s New in JSF: A Complete Tour of JSF 2.2,” in which he provided an update on recent developments in JavaServer Faces 2.2. He began by emphasizing that, “JavaServer Faces 2.2 continues the evolution of the Java EE standard user interface technology. Like previous releases, this iteration is very community-driven and transparent.” He pointed out that since JSF was introduced at the 2001 JavaOne Keynote, it has had a long and successful run and has found a home in applications where the UI logic resides entirely on the server where the model and UI logic is. In such cases, the browser performs fairly simple functions. However, developers can take advantage of the power of browsers, something that Project Avatar is focused on by letting developers author their applications so the UI logic is running on the client and communicating to the back end via RESTful web services. “Most importantly,” remarked Burns, “JSF 2.2 offers a really good migration path because even in the scope of one application you could have an app written with JSF that has its UI logic on the server and, on a gradual basis, you could migrate parts of the app over to use client-side technologies. This can be done at any level of granularity – per page or per collection of pages. It all depends on what you want to do.” His presentation, which focused on the basic new features of JSF 2.2, began by restating the scope of JSF and encouraged attendees to check out Roger Kitain’s session: CON5133 “Techniques for Responsive Real-Time Web UIs.” Burns explained that JSF has endured because, “We still need web apps that are maintainable, localizable, quick to build, accessible, secure, look great and are fun to use.” It is used on every continent – the curious can go here to check out where its unofficial usage is tracked. He emphasized the significance of the UI logic being substantially on the server. This: Separates Component Semantics from Rendering, Allows components to “own” their little patch of the UI -- encode/decode, And offers a well-defined lifecycle: Inversion of Control. Burns reminded attendees that JSR-344, the spec for JSF 2.2, is now on Java Community Process 2.8, a revised version of the JCP that allows for more openness and transparency. He then offered some tools for community access to JSF 2.2:    * Public java.net projects spec http://jsf-spec.java.net/ impl http://jsf.java.net/ Open Source: GPL+Classpath Exception    * Mailing Lists [email protected]                                Public readable archive, JSPA signed member read/write [email protected]                                     Public readable archive, any java.net member read/write                         All mail sent to jsr344-experts is sent to users. * Issue Tracker spec http://jsf-spec.java.net/issues/ impl http://jsf.java.net/issues/ JSF 2.2, which is JSR 344, has a Public Review Draft planned by December 2012 with no need for a Renewal Ballot. The Early Draft Review of JSR 344 was published on December 8, 2011. Interested developers are encouraged to offer their input. Six Big Ticket Features of JSF 2.2 Burns summarized the six big ticket features of JSF 2.2:* HTML5 Friendly Markup Support Pass through attributes and elements * Faces Flows* Cross Site Request Forgery Protection* Loading Facelets via ResourceHandler* File Upload Component* Multi-Templating He explained that he called it “HTML 5 friendly” because there is really nothing HTML 5 specific about it -- it could be 4. But it enables developers to use new elements that are present in HTML5 without having a JSF component library that is written to take advantage of those specifically. It gives the page author the ability to use plain HTML5 to write their page, but to still take advantage of the server-side available in JSF. He presented a demo showing JSF 2.2’s ability to leverage the expressiveness of HTML5. Burns then explained the significance of face flows, which offer function points and quantify how much work has taken place, something of great value to JSF users. He went on to talk about JSF 2.2.’s cross-site request forgery protection (CSRF) and offered details about how it protects applications against attack. Then he talked about JSF 2.2’s File Upload Component and explained that the final specification will have Ajax and non-Ajax support. The current milestone has non-Ajax support implemented. He then went on to explain its capacity to add facelets through ResourceHandler. Previously, JSF 2.0 added Facelets and ResourceHandler as disparate units; now in JSF 2.2 the two concepts are unified. Finally, he explained the concept of multi-templating in JSF 2.2 and went on to discuss more medium-level features of the release. For an easy, low maintenance way of staying in touch with JSF developments go to JSF’s Twitter page where every month or so, important updates are offered.

• How to Increase the VMWare Boot Screen Delay

  - by Trevor Bekolay

  If you’ve wanted to try out a bootable CD or USB flash drive in a virtual machine environment, you’ve probably noticed that VMWare’s offerings make it difficult to change the boot device. We’ll show you how to change these options. You can do this either for one boot, or permanently for a particular virtual machine. Even experienced users of VMWare Player or Workstation may not recognize the screen above – it’s the virtual machine’s BIOS, which in most cases flashes by in the blink of an eye. If you want to boot up the virtual machine with a CD or USB key instead of the hard drive, then you’ll need more than an eye’s-blink to press Escape and bring up the Boot Menu. Fortunately, there is a way to introduce a boot delay that isn’t exposed in VMWare’s graphical interface – you have to edit the virtual machine’s settings file (a .vmx file) manually. Editing the Virtual Machine’s .vmx Find the .vmx file that contains the settings for your virtual machine. You chose a location for this when you created the virtual machine – in Windows, the default location is a folder called My Virtual Machines in your My Documents folder. In VMWare Workstation, the location of the .vmx file is listed on the virtual machine’s tab. If in doubt, search your hard drive for .vmx files. If you don’t want to use Windows default search, an awesome utility that locates files instantly is Everything. Open the .vmx file with any text editor. Somewhere in this file, enter in the following line… save the file, then close out of the text editor: bios.bootdelay = 20000 This will introduce a 20 second delay when the virtual machine loads up, giving you plenty of time to press the Escape button and access the boot menu. The number in this line is just a value in milliseconds, so for a five second boot delay, enter 5000, and so on. Change Boot Options Temporarily Now, when you boot up your virtual machine, you’ll have plenty of time to enter one of the keystrokes listed at the bottom of the BIOS screen on boot-up. Press Escape to bring up the Boot Menu. This allows you to select a different device to boot from – like a CD drive. Your selection will be forgotten the next time you boot up this virtual machine. Change Boot Options Permanently When the BIOS screen comes up, press F2 to enter the BIOS Setup menu. Switch to the Boot tab, and change the ordering of the items by pressing the “+” key to move items up on the list, and the “-” key to move items down the list. We’ve switched the order so that the CD-ROM Drive boots first. Once you make this change permanent, you may want to re-edit the .vmx file to remove the boot delay. Boot from a USB Flash Drive One thing that is noticeably missing from the list of boot options is a USB device. VMWare’s BIOS just does not allow this, but we can get around that limitation using the PLoP Boot Manager that we’ve previously written about. And as a bonus, since everything is virtual anyway, there’s no need to actually burn PLoP to a CD. Open the settings for the virtual machine you want to boot with a USB drive. Click on Add… at the bottom of the settings screen, and select CD/DVD Drive. Click Next. Click the Use ISO Image radio button, and click Next. Browse to find plpbt.iso or plpbtnoemul.iso from the PLoP zip file. Ensure that Connect at power on is checked, and then click Finish. Click OK on the main Virtual Machine Settings page. Now, if you use the steps above to boot using that CD/DVD drive, PLoP will load, allowing you to boot from a USB drive! Conclusion We’re big fans of VMWare Player and Workstation, as they let us try out a ton of geeky things without worrying about harming our systems. By introducing a boot delay, we can add bootable CDs and USB drives to the list of geeky things we can try out.

• Prevent Changing the Screen Saver and Wallpaper in Windows 7

  - by Mysticgeek

  Sometimes you might not want users to have the ability to change Screen Savers and Wallpaper on Windows 7 workstations. Today we look at how to prevent them from changing either one or both. You might administer computers in your home or small office and find it annoying when users continuously change the wallpaper and Screen Savers to something obnoxious. A lot of times they might be inexperienced users and download these so-called “wonderful and free” Screen Saver/Wallpaper packages from shady sites that include loads of Spyware. Preventing users from changing them is another helpful tool to avoid wasteful time spent switching things back. Prevent Changing Screensavers & Wallpaper Using Group Policy Editor  Note: This method uses Group Policy which is not available in Home versions on Windows 7. Open the Start Menu and enter gpedit.msc into the Search box and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates \ Control Panel \ Personalization. Then in the right column double-click on Prevent changing desktop background. Now check the radio button next to Enabled, then click OK. Back on the Group Policy Screen, double-click on Prevent changing screen saver. In the next screen select the radio button next to Enable, click OK, then close out of Group Policy Editor. Now when a user goes into the Personalization section, the Desktop Background hyperlink is now grayed out and inactive. Notice the message One or more of the settings on this page has been disabled by the system administrator at the bottom of the section. If they click to change the Screen Saver, an error message will pop up letting them know the function is disabled. Prevent Changing Screensavers & Wallpaper Using a Registry Hack You can also make a couple Registry changes to prevent users from changing the Wallpaper & Screen Saver…which will work on Home versions of Windows 7. Before making any Registry changes make sure you back it up first. Open the Registry by typing regedit into the Search box in the Start menu and hit Enter. First we’ll start with the Wallpaper. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new String Value and name it Wallpaper. Then modify the Value data to point to the location of the Wallpaper you want it to always be. Where in this example it’s our main wallpaper on our local drive…then click OK. Now let’s make sure they can’t change the Screen Saver. In the same Registry location, we need to make a new DWORD (32-bit) Value. Give it the Value name of NoDispScrSavPage and the value data of “1” and click OK. Close out of the Registry and restart the machine or simply log off then back on again for the changes to take effect. Results For the Wallpapers, a user can still go in and see the selections, however if they try to change it to something else… It will just go back to the Personalization screen and no changes will be made, as we set the value to only be the background we specified. If the user tries to make a change to the Screen Saver, the hyperlink will be grayed out and inactive, and the message One or more of the settings on this page has been disabled by the system administrator will be displayed at the bottom of the section. Conclusion If you’re tired of users changing the Wallpaper and Screen Saver, and want another way to help avoid Malware, locking down these settings can help a lot. Again, before making any changes to the Registry, make sure to back it up. These settings should work in Vista and XP as well.

• Superpower Your Touchpad Computer with Scrybe

  - by Matthew Guay

  Are you looking for a way to help your Touchpad computer make you more productive?  Here’s a quick look at Scrybe, a new application from Synaptics that lets you superpower it. Touchpad devices have become increasingly more interesting as they’ve included support for multi-touch gestures.  Scrybe takes it to the next level and lets you use your touchpad as an application launcher.  You can launch any application, website, or complete many common commands on your computer with a simple gesture.  Scrybe works with most modern Synaptics touchpads, which are standard on most laptops and netbooks.  It is optimized for newer multi-touch touchpads, but can also work with standard single-touch touchpads.  It works on Windows 7, Vista, and XP, so chances are it will work with your laptop or netbook. Get Started With Scrybe Head over to the Scrybe website and download the latest version (link below).  You are asked to enter your email address, name, and information about your computer…but you actually only have to enter your email address.  Click Download when finished. Run the installer when it’s download.  It will automatically download the latest Synaptics driver for your touchpad and any other components needed for Scrybe.  Note that the Scrybe installer will ask to install the Yahoo! toolbar, so uncheck this to avoid adding this worthless browser toolbar. Using Scrybe To open an application or website with a gesture, press 3 fingers on your touchpad at once, or if your touchpad doesn’t support multi-touch gestures, then press Ctrl+Alt and press 1 finger on your touchpad.  This will open the Scrype input pane; start drawing a gesture, and you’ll see it on the grey square.  The input pane shows some default gestures you can try. Here we drew an “M”, which opens our default Music player.  As soon as you finish the gesture and lift up your finger, Scrybe will open the application or website you selected. A notification balloon will let you know what gesture was preformed. When you’re entering your gesture, the input pane will show white “ink”.  The “ink” will turn blue if the command is recognized, but will turn red if it isn’t.  If Scrybe doesn’t recognize your command, press 3 fingers and try again. Scrybe Control Panel You can open the Scrybe Control panel to enter or change commands by entering a box-like gesture, or right-clicking the Scrybe icon in your system tray and selecting “Scrybe Control Panel”. Scrybe has many pre-configured gestures that you can preview and even practice. All of the gestures in the Popular tab are preset and cannot be changed.  However, the ones in the favorites tab can be edited.  Select the gesture you wish to edit, and click the gear icon to change it.  Here we changed the email gesture to open Hotmail instead of the default Yahoo Mail. Scrybe can also help you perform many common Windows commands such as Copy and Undo.  Select the Tools tab to see all of these commands.   Scrybe has many settings you may wish to change.  Select the Preferences button in the Control Panel to change these.  Here’s some of the settings we changed. Uncheck “Display a message” to turn off the tooltip notifications when you enter a gesture Uncheck “Show symbol hints” to turn off the sidebar on the input pane Select the search engine you want to open with the Search Gesture.  The default is Yahoo, but you can choose your favorite. Adding a new Scrybe Gesture The default Scrybe options are useful, but the best part is that you can assign gestures to your own programs or websites.  Open the Scrybe control panel, and click the plus sign on the bottom left corner.  Enter a name for your gesture, and then choose if it is for a website or an application. If you want the gesture to open a website, enter the address in the box. Alternately, if you want your gesture to open an application, select Launch Application and then either enter the path to the application, or click the button beside the Launch field and browse to it. Now click the down arrow on the blue box and choose one of the gestures for your application or website. Your new gesture will show up under the Favorites tab in the Scrybe control panel, and you can use it whenever you want from Scrybe, or practice the gesture by selecting the Practice button. Conclusion If you enjoy multi-touch gestures, you may find Scrybe very useful on your laptop or netbook.  Scrybe recognizes gestures fairly easily, even if you don’t enter them perfectly correctly.  Just like pinch-to-zoom and two-finger scroll, Scrybe can quickly become something you miss on other laptops.

• Java EE at JavaOne - A Few Picks from a Very Rich Line-up

  - by Janice J. Heiss

  A rich and diverse set of sessions cast a spotlight on Java EE at this year’s JavaOne, ranging from the popular Web Framework Smackdown, to Java EE 6 and Spring, to sessions exploring Java EE 7, and one on the implications of HTML5. Some of the world’s best EE architects and developers will be sharing their insight and expertise. If only I could be at ten places at once!BOF4149 - Web Framework Smackdown 2012    Markus Eisele - Principal IT Architect, msg systems ag    Graeme Rocher - Senior Staff Engineer, VMware    James Ward - Developer Evangelist, Heroku    Ed Burns - Consulting Member of Technical Staff, Oracle    Santiago Pericasgeertsen - Software Engineer, Oracle* Monday, Oct 1, 8:30 PM - 9:15 PM - Parc 55 - Cyril Magnin II/III Much has changed since the first Web framework smackdown, at JavaOne 2005. Or has it? The 2012 edition of this popular panel discussion surveys the current landscape of Web UI frameworks for the Java platform. The 2005 edition featured JSF, Webwork, Struts, Tapestry, and Wicket. The 2012 edition features representatives of the current crop of frameworks, with a special emphasis on frameworks that leverage HTML5 and thin-server architecture. Java Champion Markus Eisele leads the lively discussion with panelists James Ward (Play), Graeme Rocher (Grails), Edward Burns (JSF) and Santiago Pericasgeertsen (Avatar).CON6430 - Java EE and Spring Framework Panel Discussion    Richard Hightower - Developer, InfoQ    Bert Ertman - Fellow, Luminis    Gordon Dickens - Technical Architect, IT101, Inc.    Chris Beams - Senior Technical Staff, VMware    Arun Gupta - Technology Evangelist, Oracle* Tuesday, Oct 2, 10:00 AM - 11:00 AM - Parc 55 - Cyril Magnin II/III In the age of Java EE 6 and Spring 3, enterprise Java developers have many architectural choices, including Java EE 6 and Spring, but which one is right for your project? Many of us have heard the debate and seen the flame wars—it’s a topic with passionate community members, and it’s a vibrant debate. If you are looking for some level-headed discussion, grounded in real experience, by developers who have tried both, then come join this discussion. InfoQ’s Java editors moderate the discussion, and they are joined by independent consultants and representatives from both Java EE and VMWare/SpringSource.BOF4213 - Meet the Java EE 7 Specification Leads   Linda Demichiel - Consulting Member of Technical Staff, Oracle   Bill Shannon - Architect, Oracle* Tuesday, Oct 2, 5:30 PM - 6:15 PM – Parc 55 - Cyril Magnin II/III This is your chance to meet face-to-face with the engineers who are developing the next version of the Java EE platform. In this session, the specification leads for the leading technologies that are part of the Java EE 7 platform discuss new and upcoming features and answer your questions. Come prepared with your questions, your feedback, and your suggestions for new features in Java EE 7 and beyond.CON10656 - JavaEE.Next(): Java EE 7, 8, and Beyond    Ian Robinson - IBM Distinguished Engineer, IBM    Mark Little - JBoss CTO, NA    Scott Ferguson - Developer, Caucho Technology    Cameron Purdy - VP Development, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin II/IIIIn this session, hear from a distinguished panel of industry and open source luminaries regarding where they believe the Java EE community is headed, starting with Java EE 7. The focus of Java EE 7 and 8 is mostly on the cloud, specifically aiming to bring platform as a service (PaaS) providers and application developers together so that portable applications can be deployed on any cloud infrastructure and reap all its benefits in terms of scalability, elasticity, multitenancy, and so on. Most importantly, Java EE will leverage the modularization work in the underlying Java SE platform. Java EE will, of course, also update itself for trends such as HTML5, caching, NoSQL, ployglot programming, map/reduce, JSON, REST, and improvements to existing core APIs.CON7001 - HTML5 WebSocket and Java    Danny Coward - Java, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin IThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform.

• PASS: 2013 Summit Location

  - by Bill Graziano

  HQ recently posted a brief update on our search for a location for 2013.  It includes links to posts by four Board members and two community members. I’d like to add my thoughts to the mix and ask you a question.  But I can’t give you a real understanding without telling you some history first. So far we’ve had the Summit in Chicago, San Francisco, Orlando, Dallas, Denver and Seattle.  Each has a little different feel and distinct memories.  I enjoyed getting drinks by the pool in Orlando after the sessions ended.  I didn’t like that our location in Dallas was so far away from all the nightlife.  Denver was in downtown but we had real challenges with hotels.  I enjoyed the different locations.  I always enjoyed the announcement during the third keynote with the location of the next Summit. There are two big events that impacted my thinking on the Summit location.  The first was our transition to the new management company in early 2007.  The event that September in Denver was put on with a six month planning cycle by a brand new headquarters staff.  It wasn’t perfect but came off much better than I had dared to hope.  It also moved us out of the cookie cutter conferences that we used to do into a model where we have a lot more control.  I think you’ll all agree that the production values of our last few Summits have been fantastic.  That Summit also led to our changing relationship with Microsoft.  Microsoft holds two seats on the PASS Board.  All the PASS Board members face the same challenge: we all have full-time jobs and PASS comes in second place professionally (or sometimes further back).  Starting in 2008 we were assigned a liaison from Microsoft that had a much larger block of time to coordinate with us.  That changed everything between PASS and Microsoft.  Suddenly we were talking to product marketing, Microsoft PR, their event team, the Tech*Ed team, the education division, their user group team and their field sales team – locally and internationally.  We strengthened our relationship with CSS, SQLCAT and the engineering teams.  We had exposure at the executive level that we’d never had before.  And their level of participation at the Summit changed from under 100 people to 400-500 people.  I think those 400+ Microsoft employees have value at a conference on Microsoft SQL Server.  For the first time, Seattle had a real competitive advantage over other cities. I’m one that looked very hard at staying in Seattle for a long, long time.  I think those Microsoft engineers have value to our attendees.  I think the increased support that Microsoft can provide when we’re in Seattle has value to our attendees.  But that doesn’t tell the whole story.  There’s a significant (and vocal!) percentage of our membership that wants the Summit outside Seattle.  Post-2007 PASS doesn’t know what it’s like to have a Summit outside of Seattle.  I think until we have a Summit in another city we won’t really know the trade-offs. I think a model where we move every third or every other year is interesting.  But until we have another Summit outside Seattle and we can evaluate the logistics and how important it is to have depth and variety in our Microsoft participation we won’t really know. Another benefit that comes with a move is variety or diversity.  I learn more when I’m exposed to new things and new people.  I believe that moving the Summit will give a different set of people an opportunity to attend. Grant Fritchey writes “It seems that the board is leaning, extremely heavily, towards making it a permanent fixture in Seattle.”  I don’t believe that’s true.  I know there was discussion of that earlier but I don’t believe it’s true now. And that brings me to my question.  Do we announce the city now or do we wait until the 2012 Summit?  I’m happy to announce Seattle vs. not-Seattle as soon as we sign the contract.  But I’d like to leave the actual city announcement until the 2011 Summit.  I like the drama and mystery of it.  I also like that it doesn’t give you a reason to skip a Summit and wait for the next one if it’s closer or back in Seattle.  The other side of the coin is that your planning is easier if you know where it is.  What do you think?

• Where would a spam bot be located?

  I have a hosted website using a free hosting service, I received an email this afternoon saying that I have been suspended because my account has been compromised.

• WSDLException : An error occurred trying to resolve schema referenced at ...

  Hello i'm trying to generate a proxy class from a local wsdl file with eclipse Galileo and axis 2 1.4 on windows xp . My problem is that i get an error due to an imported schema inside the wsdl . The line tha troubles me is : <xsd:import namespace="http://www.w3.org/2005/05/xmlmime" schemaLocation="http://www.w3.org/2005/05/xmlmime"/> i've tried to run the wsdl2java following command: wsdl2java.bat -uri SOAService.wsdl -o D:\temp p test -d xmlbeans -a -s -ns2p -uw and i get the following exception : Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException : Error parsing WSDL at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerat ionEngine.java:156) at org.apache.axis2.wsdl.WSDL2Code.main(WSDL2Code.java:35) at org.apache.axis2.wsdl.WSDL2Java.main(WSDL2Java.java:24) Caused by: javax.wsdl.WSDLException: WSDLException (at /wsdl:definitions/wsdl:ty pes/xsd:schema): faultCode=OTHER_ERROR: An error occurred trying to resolve sche ma referenced at 'http://www.w3.org/2005/05/xmlmime', relative to 'file:/D:/Prog rammi/axis2-1.4/bin/SOAService.wsdl'.: java.net.ConnectException: Connection tim ed out: connect at com.ibm.wsdl.xml.WSDLReaderImpl.parseSchema(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.parseSchema(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.parseTypes(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.parseDefinitions(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.readInTheWSDLFile( CodeGenerationEngine.java:288) at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerat ionEngine.java:111) ... 2 more Caused by: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) at java.net.Socket.connect(Socket.java:520) at java.net.Socket.connect(Socket.java:470) at sun.net.NetworkClient.doConnect(NetworkClient.java:157) at sun.net.www.http.HttpClient.openServer(HttpClient.java:388) at sun.net.www.http.HttpClient.openServer(HttpClient.java:523) at sun.net.www.http.HttpClient.(HttpClient.java:231) at sun.net.www.http.HttpClient.New(HttpClient.java:304) at sun.net.www.http.HttpClient.New(HttpClient.java:321) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLC onnection.java:813) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConne ction.java:765) at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection .java:690) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLCon nection.java:934) at java.net.URL.openStream(URL.java:1007) at com.ibm.wsdl.util.StringUtils.getContentAsInputStream(Unknown Source) i suspect it's due to the system proxy which doesn't let retrieve the xsd to the wsdl2java tool. In fact i can download the file from the browser without problems. There's an option to specify a proxy to wsdl2java or someone has resolved this issue ? For the moment i've downloaded the xsd, added it to the project and changed the wsdl to include the relative file (instead of the remote one) , but i'd prefer to avoid this , because the file is a third party service wsdl. thank you in advance for any hint Stefano

• PHP5.3 is not working with MySQL5.1 IIS7 Times out

  I have set up PHP5.3, MySQL5.1, and IIS7 on Window 7 but php doesn't want to work with MySQL. I'm assuming it is a configuration error or an incomplete install on my part. MySQL5.1 is working PHP5.3 is working, phpinfo() shows info and that i have enabled MySQL IIS is setup and using fastCgiModule to run PHP IIS registers php.ini updates port 3306 is firewall free and open to the world php.ini is configured correctly I have added c:\php to the Windows systems PATH In the past I remember moving a file, libmysql.dll, to System32 but I doesn't look like that come with php5.3.1, as the driver comes built in now http://us3.php.net/manual/en/mysqlnd.install.php. (This has been giving me so much trouble I have been documenting my findings on my blog as http://inteldesigner.com/2010/code/having-problems-getting-php5-3-to-work-with-mysql5-1 ) NEED: I need to install PHP manually, don't want to use the quick installer or an older version I need to get PHP5.3 to work with MySQL5.1 so i can install Wordpress2.9 and Drupal7a Any links or suggestion would be great, I have already done everything on the iis web site, nothing is working. I'm guessing they have not updated for new software.

• For loop from assembly to C

  - by FranXh

  I have a bomb project where I need to defuse certain phases by finding "pas phrases" that will defuse the bomb. Right now I have been working with phase_2, for which the assembly code is shown below. Phase_2 requires as an input 6 numbers, which I need to find in order to defuse this phase. I analyzed this assembly, and I came up with the C code below, that covers lines from 40101c to 401044. It is basically a for loop that makes sure that elements t[0]==t[3], t[1]==t[4] and t[2]==t[5] that the user inputs, are equal. According to my logic, the user can input any 6 numbers as long as the above condition is satisfied. Say 1, 2, 3, 1, 2, 3 would be a valid "pas phrase". However this solution does not convince me for some reason. Am I doing something wrong? 0000000000400ffc <phase_2>: 400ffc: 48 89 5c 24 e0 mov %rbx,-0x20(%rsp) 401001: 48 89 6c 24 e8 mov %rbp,-0x18(%rsp) 401006: 4c 89 64 24 f0 mov %r12,-0x10(%rsp) 40100b: 4c 89 6c 24 f8 mov %r13,-0x8(%rsp) 401010: 48 83 ec 48 sub $0x48,%rsp 401014: 48 89 e6 mov %rsp,%rsi 401017: e8 65 0a 00 00 callq 401a81 <read_six_numbers> 40101c: 48 89 e5 mov %rsp,%rbp 40101f: 4c 8d 6c 24 0c lea 0xc(%rsp),%r13 401024: 41 bc 00 00 00 00 mov $0x0,%r12d 40102a: 48 89 eb mov %rbp,%rbx 40102d: 8b 45 0c mov 0xc(%rbp),%eax 401030: 39 45 00 cmp %eax,0x0(%rbp) 401033: 74 05 je 40103a <phase_2+0x3e> 401035: e8 2d 09 00 00 callq 401967 <_GLOBAL_RESET_> 40103a: 44 03 23 add (%rbx),%r12d 40103d: 48 83 c5 04 add $0x4,%rbp 401041: 4c 39 ed cmp %r13,%rbp 401044: 75 e4 jne 40102a <phase_2+0x2e> 401046: 45 85 e4 test %r12d,%r12d 401049: 75 05 jne 401050 <phase_2+0x54> 40104b: e8 17 09 00 00 callq 401967 <_GLOBAL_RESET_> 401050: 48 8b 5c 24 28 mov 0x28(%rsp),%rbx 401055: 48 8b 6c 24 30 mov 0x30(%rsp),%rbp 40105a: 4c 8b 64 24 38 mov 0x38(%rsp),%r12 40105f: 4c 8b 6c 24 40 mov 0x40(%rsp),%r13 401064: 48 83 c4 48 add $0x48,%rsp 401068: c3 for (int i=0; i<3; i++){ if(t[i] != t[i+3]){ explode(); } }

• java.util.zip - ZipInputStream v.s. ZipFile

  - by lucho

  Hello, community! I have some general questions regarding the java.util.zip library. What we basically do is an import and an export of many small components. Previously these components were imported and exported using a single big file, e.g.: <component-type-a id="1"/> <component-type-a id="2"/> <component-type-a id="N"/> <component-type-b id="1"/> <component-type-b id="2"/> <component-type-b id="N"/> Please note that the order of the components during import is relevant. Now every component should occupy its own file which should be externally versioned, QA-ed, bla, bla. We decided that the output of our export should be a zip file (with all these files in) and the input of our import should be a similar zip file. We do not want to explode the zip in our system. We do not want opening separate streams for each of the small files. My current questions: Q1. May the ZipInputStream guarantee that the zip entries (the little files) will be read in the same order in which they were inserted by our export that uses ZipOutputStream? I assume reading is something like: ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis)); ZipEntry entry; while((entry = zis.getNextEntry()) != null) { //read from zis until available } I know that the central zip directory is put at the end of the zip file but nevertheless the file entries inside have sequential order. I also know that relying on the order is an ugly idea but I just want to have all the facts in mind. Q2. If I use ZipFile (which I prefer) what is the performance impact of calling getInputStream() hundreds of times? Will it be much slower than the ZipInputStream solution? The zip is opened only once and ZipFile is backed by RandomAccessFile - is this correct? I assume reading is something like: ZipFile zipfile = new ZipFile(argv[0]); Enumeration e = zipfile.entries();//TODO: assure the order of the entries while(e.hasMoreElements()) { entry = (ZipEntry) e.nextElement(); is = zipfile.getInputStream(entry)); } Q3. Are the input streams retrieved from the same ZipFile thread safe (e.g. may I read different entries in different threads simultaneously)? Any performance penalties? Thanks for your answers!

• Why an object declared in method is subject to garbage collection before the method returns?

  - by SiLent SoNG

  Consider an object declared in a method: public void foo() { final Object obj = new Object(); // A long run job that consumes tons of memory and // triggers garbage collection } Will obj be subject to garbage collection before foo() returns? UPDATE: Previously I thought obj is not subject to garbage collection until foo() returns. However, today I find myself wrong. I have spend several hours in fixing a bug and finally found the problem is caused by obj garbage collected! Can anyone explain why this happens? And if I want obj to be pinned how to achieve it? Here is the code that has problem. public class Program { public static void main(String[] args) throws Exception { String connectionString = "jdbc:mysql://<whatever>"; // I find wrap is gc-ed somewhere SqlConnection wrap = new SqlConnection(connectionString); Connection con = wrap.currentConnection(); Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY); stmt.setFetchSize(Integer.MIN_VALUE); ResultSet rs = stmt.executeQuery("select instance_id, doc_id from crawler_archive.documents"); while (rs.next()) { int instanceID = rs.getInt(1); int docID = rs.getInt(2); if (docID % 1000 == 0) { System.out.println(docID); } } rs.close(); //wrap.close(); } } After running the Java program, it will print the following message before it crashes: 161000 161000 ******************************** Finalizer CALLED!! ******************************** ******************************** Close CALLED!! ******************************** 162000 Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: And here is the code of class SqlConnection: class SqlConnection { private final String connectionString; private Connection connection; public SqlConnection(String connectionString) { this.connectionString = connectionString; } public synchronized Connection currentConnection() throws SQLException { if (this.connection == null || this.connection.isClosed()) { this.closeConnection(); this.connection = DriverManager.getConnection(connectionString); } return this.connection; } protected void finalize() throws Throwable { try { System.out.println("********************************"); System.out.println("Finalizer CALLED!!"); System.out.println("********************************"); this.close(); } finally { super.finalize(); } } public void close() { System.out.println("********************************"); System.out.println("Close CALLED!!"); System.out.println("********************************"); this.closeConnection(); } protected void closeConnection() { if (this.connection != null) { try { connection.close(); } catch (Throwable e) { } finally { this.connection = null; } } } }

• Ruby: Parse, replace, and evaluate a string formula

  - by Swartz

  I'm creating a simple Ruby on Rails survey application for a friend's psychological survey project. So we have surveys, each survey has a bunch of questions, and each question has one of the options participants can choose from. Nothing exciting. One of the interesting aspects is that each answer option has a score value associated with it. And so for each survey a total score needs to be calculated based on these values. Now my idea is instead of hard-coding calculations is to allow user add a formula by which the total survey score will be calculated. Example formulas: "Q1 + Q2 + Q3" "(Q1 + Q2 + Q3) / 3" "(10 - Q1) + Q2 + (Q3 * 2)" So just basic math (with some extra parenthesis for clarity). The idea is to keep the formulas very simple such that anyone with basic math can enter them without resolving to some fancy syntax. My idea is to take any given formula and replace placeholders such as Q1, Q2, etc with the score values based on what the participant chooses. And then eval() the newly formed string. Something like this: f = "(Q1 + Q2 + Q3) / 2" # some crazy formula for this survey values = {:Q1 => 1, :Q2 => 2, :Q3 => 2} # values for substitution result = f.gsub(/(Q\d+)/) {|m| values[$1.to_sym] } # string to be eval()-ed eval(result) So my questions are: Is there a better way to do this? I'm open to any suggestions. How to handle formulas where not all placeholders were successfully replaced (e.g. one question wasn't answered)? Ex: {:Q3 = 2} wasn't in values hash? My idea is to rescue eval()... any thoughts? How to get proper result? Should be 2.5, but due to integer arithmetic, it will truncate to 2. I can't expect people who provide the correct formula (e.g. / 2.0 ) to understand this nuance. I do not expect this, but how to best protect eval() from abuse (e.g. bad formula, manipulated values coming in)? Thank you!

• Why is .NET Post different from CURL? broken?

  - by ironnailpiercethesky

  I dont understand this. I ran this code below and the result json string was the link is expired (meaning invalid). However the curl code does the exact same thing and works. I either get the expected string with the url or it says i need to wait (for a few seconds to 1 minute). Why? whats the difference between the two? It looks very F%^&*ed up that it is behaving differently (its been causing me HOURS of problems). NOTE: the only cookie required by the site is SID (tested). It holds your session id. The first post activates it and the 2nd command checks the status with the returning json string. Feel free to set the CookieContainer to only use SID if you like. WARNING: you may want to change SID to a different value so other people arent activating it. Your may want to run the 2nd url to ensure the session id is not used and says expired/invalid before you start. additional note: with curl or in your browser if you do the POST command you can stick the sid in .NET cookie container and the 2nd command will work. But doing the first command (the POST data) will not work. This post function i have used for many other sites that require post and so far it has worked. Obviously checking the Method is a big deal and i see it is indeed POST when doing the first command. static void Main(string[] args) { var cookie = new CookieContainer(); PostData("http://uploading.com/files/get/37e36ed8/", "action=second_page&file_id=9134949&code=37e36ed8", cookie); Thread.Sleep(4000); var res = PostData("http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined", null/*this makes it GET*/, cookie); Console.WriteLine(res); /* curl -b "SID=37468830" -A "DUMMY_User_Aggent" -d "action=second_page&file_id=9134949&code=37e36ed8" "http://uploading.com/files/get/37e36ed8/" curl -b "SID=37468830" -A "DUMMY_User_Aggent" "http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined" */ }
