• VMware Fusion configuration files missing

  - by jdmuys

  I need to set up port forwarding to my VM in Fusion 5. Everywhere on the net, the solution is described as editing the file: /Library/Application Support/VMware Fusion/vmnet8/nat.conf However, on my install, that file doesn't exist. Neither does the vmnet8 directory. Here is the full content of VMware stuff I have in /Library/Application Support/: /Library/Application Support/ VMware/ VMware Fusion AdminWritable Shared vmInventory usbarb.rules VMware Fusion That's right: /Library/Application Support/VMware Fusion/ exists but is empty. And there is no VMware folder in other Library directories on my system. I am running OS X 10.8.2. I just reinstalled Fusion 5.02, no change. Meanwhile, I have 3 VMs that work just fine. So how am I supposed to set up port forwarding with Fusion 5? Thanks, JD Edit: in a hunch, I tried ps ax | grep natd which returned: 9646 ?? S 0:00.01 /Applications/VMware Fusion.app/Contents/Library/vmnet-natd -s 7 -m /Library/Preferences/VMware Fusion/vmnet8/nat.mac -c /Library/Preferences/VMware Fusion/vmnet8/nat.conf So it seems that the configurations files are now in the directory /Library/Preferences/VMware Fusion. I'll work from here and edit this question as I make progress.

• Oracle 10g for Windows does not start up on system boot

  - by Mike Dimmick

  We have an Oracle 10g Enterprise Edition installation (10.2.0.1.0) on a Windows Server 2003 virtual machine. It was initially created with Virtual Server 2005 R2 SP1 but has now been migrated to Windows Server 2008 Hyper-V. The services start on system boot, but the instance does not start up. This problem was actually occurring on Virtual Server after a migration from one server to another, but I managed to fix it then with: oradim -edit -sid ORCL -startmode auto However, this now has no effect. oradim.log (in %OracleHome%\database\oradim.log) says: Thu Jun 10 14:14:48 2010 C:\oracle\product\10.2.0\db_3\bin\oradim.exe -startup -sid orcl -usrpwd * -log oradim.log -nocheck 0 Thu Jun 10 14:14:48 2010 ORA-12560: TNS:protocol adapter error sqlnet.log in the same folder has: Fatal NI connect error 12560, connecting to: (DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleorcl)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_3\bin\oradim.exe)(HOST=ORACLE-VM)(USER=SYSTEM)))) VERSION INFORMATION: TNS for 32-bit Windows: Version 10.2.0.1.0 - Production Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 10.2.0.1.0 - Production Time: 10-JUN-2010 14:14:48 Tracing not turned on.

I'd still like to work out why it's not working.

• Toshiba laptop cd drive read causes OS to totally freeze

  - by Fujishiro

  Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

• can't access SATA card config screen on boot, nor access the disks

  - by Ronald

  We've just upgraded our file server using an ASUS P6T WS Pro board, running FreeBSD-RELEASE 8.2 and using zfs to manage 12 WD20EARS disks. Since our 3ware card has been giving us trouble we started using the six on-board SATA connectors and got a SuperMicro USAS2-L8i to provide eight more ports. Mechanically, the card is an awkward fit but electrically it all seems ok. Upon boot, the LSI controller shows up and states that pressing ctrl-c will bring up the LSI Config Utility. When doing that, the message changes to state that the utility will be started after initialization, however that never happens. There does seem to be an error message that's only displayed too briefly to read and seems to be about PCI and "not enough space". (That message is pushed off by a hardware summary and I've found no way to scroll back at this point.) The disks do not show up in any recognizable ways after booting, either. I found a hint in another discussion to check the address mapping on either the card or the motherboard BIOS, but have found no way to do that. So what I tried on a hunch is to disable everything that's on-board, including network adapters, Firewire controller and SATA. In fact, after doing that, I can successfully launch the LSI Config Utility. As far as I can tell, all looks well in there, and when booting in that configuration it also displays a list of the disks connected to it, which looks just fine as well. Only problem now is that I can't boot that way, because I need the on-board SATA controller and network adapters. As soon as I re-enable any of them I'm back to square one. That discussion I mentioned about mapping addresses said to try D000, then D7FF, then DFFF, in order. The LSI Config Utility shows the card address as D000 but offers no way of changing it. Any tips or insights would be appreciated.

• Locating memory leak in Apache httpd process, PHP/Doctrine-based application

  - by Sam

  I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

• SQL Server 2008 second instance times out when logging in -- but only the first time?

  - by Kromey

  This is a strange one that has plagued me for a while now. When logging in to the second instance of SQL Server 2008 on one of our database servers, we get a timeout error: Cannot connect to servername\mssqlserver2. Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server)") (This is the error message when trying to connect with Microsoft SQL Server Management Studio; other tools experience the same error, but of course say it in different ways.) Immediately re-attempting to log in works just fine, so whatever the cause it's ephemeral! This happens regardless of user or authentication type (both Windows and SQL Server authentication methods are supported on this instance). What's even weirder, though, is that the first instance on this server has never once demonstrated this problem. Server is a Windows Server 2008 R2 virtual server, hosted in Microsoft Hyper-V (host is likewise Server 2008 R2). The server has 2GB of RAM, and seems to regularly be using 90% of that -- could low memory be the cause of this issue? I could see this second instance -- which is not used very often yet -- being swapped out to disk, and then taking too long to load back into memory to respond in time to the connection request, but I'd rather have more than just my own hunch before I go scheduling a downtime for this server (the first instance is used regularly) and then just throwing extra resources at it in the blind hope that the problem goes away.

• Would an invalid certificate cause an 0x8004010F sync error?

  - by hydroparadise

  We just migrated from Exchange 2003 to 2007 which was a combo primary AD/DNS server and it has not gone smoothly. We are now down to getting a new certificate (a bureaucratic process thats out of my hands) and users getting the 0x8004010F sync issue. We are only using Outlook 2007 as our email client and the sync error appears exactly as so: 9:21:44 Synchronizer Version 12.0.6562 9:21:44 Synchronizing Mailbox '<User>' 9:21:44 Done 9:21:44 Microsoft Exchange offline address book 9:21:44 0X8004010F Now, I have read a number of technet articles on this issue anywhere from adding an A record in the DNS for autodiscover.domain.com to syncing the old OAD to the new OAD. In otherwords, theres lots of thing to try, but trial and error at this point might be hazardous to ther server's health and I am trying to narrow down the list of things to try. What has me thinking that the sync error could be related to the certificate is an event error message that says the following: Microsoft Exchange could not find a certificate that contains the domain name mail.ccufl.org in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Internet Mail with a FQDN parameter of mail.ccufl.org. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. I am not fully clear on how the Exchange Transport Service is related to Syncronization, but my hunch is that it probably not related to there not being a valid certificate. So to recap, would an invalid certificate cause an 0x8004010F sync error?

• Is it possible to have a conditional formatting cell "visually cycle" through all the formats that evaluated true?

  - by Ben

  Like the title says, "In Excel, when a cell has multiple conditional formatting rules that evaluate true, is it possible to have the cell "visually cycle" through all the formats that evaluated true? If not, suggestions on what to do would be appreciated!" I'm creating an employee schedule for a business that has multiple job areas that need to have an employee assigned to cover. The schedule is currently set up with the date on the top row, employee list down the left column, and the employee's assigned "job area" cross-referencing with the date on the top row. Originally it was set up where if every required "job area" didn't have someone assigned to it, the date would (via conditional formatting) change to red. I've set it up now that if a condition isn't met, the date will change to the color of the "job area" that doesn't have an employee assigned to it. However, there are cases where multiple job areas don't have an employee assigned, but the date will only change color based on the first condition that isn't met. It'd be nice if there was some way for the date cell to cycle through the different colors that correspond to the job areas where no one is assigned. I have a hunch that's not possible though. If it is possible, I'd love to know how to do it. And if it isn't, if anyone has any suggestions on how I can modify the Excel sheet to make it easier to identify the job areas that don't have anyone assigned to them, I would appreciate it. FYI This schedule goes out months in advance.

• Can I use @import to import Kod's default style sheet into my own?

  - by Thomas Upton

  I understand that Kod is being actively developed and is prone to drastic changes in any area. I would like to modify some small things (like font face and size or certain colors) while still being able to benefit from any changes or updates to the default Kod stylesheet. I thought that I would be able to @import the default stylesheet into my own to achieve this. This is what ~/.kod/custom.css would look like, @import url("file:///Applications/Kod.app/Contents/Resources/style/default.css"); /* Change the default font face and color. */ body { font-family: Menlo, monospace; color: #efefef; } This stylesheet was set with the following defaults command, per the comments at the top of Kod's default CSS file: defaults write se.hunch.kod style/url ~/.kod/custom.css Unfortunately, this didn't work. When I first tried to reload the style, Kod crashed. It opened fine again, but the @import statement wasn't working, and Kod crashed every time I saved the custom.css file. Am I doing something wrong? Did I write my @import statement wrong? Is that not how @import is supposed to work? Did I miss some sort of documentation or Kod Google Groups post that mentions that Kod explicitly disallows this?

• fglrx-legacy-driver not seeing Radeon HD 4650 AGP

  - by Rocket Hazmat

  I am running Debian Squeeze on an old Dell Dimension 8300 box. It has an AGP Radeon HD 4650 card. I use this machine to mine bitcoins, and today I noticed that the machine had rebooted! My precious uptime! Anyway, my miner wouldn't start, so I figured might as well update my graphics driver, maybe that would fix the issue. I went to amd.com and downloaded the newest driver (12.6 legacy), but after installing it, aticonfig gave an error: aticonfig: No supported adapters detected I uninstalled the driver and figured I'd try to install it from apt. AMD has dropped support for the HD 4000 series in fglrx, forcing me to use fglrx-legacy-driver (currently only in experimental). In order to install this, I had to update libc6 (and some other important packages, like gcc), I had to use their wheezy versions. I finally got fglrx-legacy-driver installed, but I still got: aticonfig: No supported adapters detected Why isn't the driver finding my video card? I have a hunch it has something to do with the fact that it's an AGP video card. Here is the output of lspci -v (why does it say Kernel driver in use: fglrx_pci?): 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV730 Pro AGP [Radeon HD 4600 Series] (prog-if 00 [VGA controller]) Subsystem: Advanced Micro Devices [AMD] nee ATI Device 0028 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at e0000000 (32-bit, prefetchable) [size=256M] I/O ports at de00 [size=256] Memory at fe9f0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at fea00000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Capabilities: [58] AGP version 3.0 Kernel driver in use: fglrx_pci EDIT: fglrx 12.4 seems to work. Thing is, since I am on kernel 3.2, I need to apply this patch to common/lib/modules/fglrx/build_mod/firegl_public.c. I thought ATI dropped support for the 4xxx series after 12.4. Why doesn't 12.6 legacy work?

• SVG doesn't work on subdomain - some browsers try to download rather than display

  - by John Catterfeld

  I have a site with a 'development' subdomain, which displays my SVG file exactly as intended. However when I copy it across to www, or any other subdomain (e.g. 'test') some browsers try to open the file in an external editor, therefore asking me to download the file rather than displaying it. For example: http://development.mysite.com/test.svg - works http://www.mysite.com/test.svg - doesn't work The SVG file: <?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" /> </svg> This happens in Firefox, Chrome and Safari, however IE9 and above display the file as intended. It is a Windows hosting, and I have <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> in my web.config file My hunch is that there must be some setting on the server which I need my hosting company to make. Can anyone suggest what might cause this issue?

• MySQL (local) owner and permissions

  - by Steve Nelson

  I asked this question on the MySQL forums and got no answer. I asked on StackOverflow and received a recommendation to try on ServerFault. So here I am. I recently successfully installed the 64 bit version of mysql-5.5.8 on a MacBook Pro in the /usr/local directory. To address a completely unrelated software (RVM actually) , I chown-ed my /usr/local directory to $USER, Which made MySQL very unhappy. It complained specifically about the /usr/local/mysql/data directory, so I chown-ed that directory to _mysql:wheel. Everything appears to work again, but it made me wonder if I would have been better off changing the owner of the whole /usr/local/mysql directory, not just the data subdirectory. Since I neglected to make notes of what owner the default installation runs under before rashly changing the owner of the /usr/local directory, could someone tell me what owner and permissions the /usr/local/mysql directory is by default if you don't inadvertently screw it up? :-/ In terms of permissions I'm guessing rwxr-xr-x would be appropriate (that's what the data directory currently has and it appears to be working fine), but reinforcement for that hunch would be appreciated. Thanks for any help. Steve

• Pushing Windows Store apps silently

  - by seagull

  As part of a requirement I have been issued, I seek the ability to push apps from the Windows Store (.appx) to remote users. The framework surrounding the data transmission is sorted; What I need to know is if there is a script that can be sent out along with a URI or the package proper to facilitate installation on the user-side of the Windows Store app. I am well aware that numerous guides exist from Microsoft on pushing out Line-of-Business (LOB) (AKA Enterprise) applications -- that is, apps that have been developed in-house and are not for the consumption of the Windows store. This is inappropriate for my requirement, however; the customer wants their clients to receive apps that appear currently on the Windows Store, and for them to be installed in a silent manner. I've seen this guide; http://blogs.technet.com/b/keithmayer/archive/2013/02/25/step-by-step-deploying-windows-8-apps-with-system-center-2012-service-pack-1.aspx, which details doing exactly this, but it is only applicable to machines that are administered by a system running Windows Server 2012 R2 with the 'System Center 2012' bundle installed. The systems I target are considerably more decentralised than this, making this guide inappropriate. I have a hunch that Microsoft have deliberately designed the Windows Store to be this way, but I figured I ought to ask around before I resign myself to the requirement. Much obliged

• Steps to debugging web site latency and timeout issues

  - by Paperjam

  I have a client who has multiple offices around the country, all of which share the same Internet connection via their WAN. One specific office for this client is experiencing severe latency and timeout issues with my web site. Most, but not all, of the latency occurs on a specific ASPX page where multiple postbacks are made while populating cascading dropdown lists (rapid form submits). The latency is sporadic and can be anywhere from a few seconds to a full timeout. There is no indication that the timeouts are occurring on the server's end. The IT guy for this client is having trouble narrowing down the problem. Since it is affecting only one location for one client, I am led to believe it is not something with my site but something specific to that location. He's measured ping times while using the site and has noticed no real variance in ping times even when the page has timed out. I believe this may be being caused by some sort of Internet filter that doesn't like rapid form submits, but beyond a hunch I haven't a clue. My question is what things should I tell the IT guy to look for? While I'm not trying to provide active tech support for this issue, I would at least like to glean an understanding of what is going on and try to offer some sort of advice. Thank you.

• Unexpected media key behavior on new Acer Aspire

  - by Morgan May

  I'm having weird issues with the media keys (play/pause, previous, next, etc.) on a new Acer Aspire laptop. This is the first Acer I've owned and also my first Windows 7 computer, so I'm not sure whether the behavior is a result of some hidden Acer process that I haven't rooted out yet, or some Windows 7 option that I'm not aware of, or something else. I'm experiencing two issues that I suspect are related. Both problems are intermittent but happen more often than not. The media player I'm using is Winamp. I'm pretty sure I've had the same problem when using other media players, but when I tried to verify that before posting this, I only had the problems with Winamp. Because the problems are intermittent, I'm not sure if that's significant. 1) When I press the Play/Pause media key, in addition to playing or pausing the media player, it brings up a little menu in the center of the screen that lists my removable drives (CD/DVD, USB drives, etc.). To make the menu go away I have to either click away from it or hit Escape. Selecting a drive on the menu doesn't seem to do anything. 2) When I press the Previous or Next media keys, it skips 2+ tracks instead of just one (the exact number seems to vary). I've poked around all the control panel options that I can find, and looked through all the utilities that came with the computer with no luck. There's nothing that I can find in the (very slim) documentation, either. I have a hunch that the problem is caused by whatever utility manages global hotkeys, but I haven't found any way to configure that. Any guidance would be greatly appreciated. UPDATE: It looks like Winamp was the culprit. I did have the problem when using other media players, but when I uninstalled Winamp, the problem went away. I'd like to use Winamp, but I can survive with other players.

I have a hunch it has something to do with the fact that it's an AGP video card.

• iPad Impressions

  - by Aaron Lazenby

  So, I spent some quality time with my new iPad on Saturday. Here are things I like/don't like: -- Don't like that it has to sync with iTunes before you use it: I was traveling and left my laptop at home thinking I'd use this iPad thing instead. But the first thing it asked me to do is connect it to a laptop. Ugh. Had to borrow my mother-in-law's MacBook Pro just to get the iPad rolling. -- Like that magazines and newspapers are forever changed: And I think for the better...it's why I bought this thing in the first place. I spent significant time with The New York Times, The Wall Street Journal, Time Magazine and Popular Science on the iPad. Sliding stories around, jumping from section to section, enlarging images = all excellent experiences. Actually prefer iPad magazine to print, which will require a major shift in editorial strategy, summed up by Popular Science's Mark Jannot in his editor's note "What defines a magazine? Curated expertise--not paper." -- Don't like the screwy human factors: I actually enjoy the virtual keyboard (although I think I'm in the minority), but you have to hunch over to look down at what you're typing. Bad technology ergonomics have already jacked my body in various ways. The iPad just introduced a new one.-- Like the multitouch: In fact, it's awesome. Hands down. Probably will have the most lasting impact on the personal computing industry as a whole.   -- Don't like that it's heavy: If you plan to read in bed, you'd better double up on the creatine and curls. Holding this thing up on your own gets pretty uncomfortable. -- Like the Netfilx app: I wanted to watch "The Big Lebowski," so I did. That is all. -- Don't like that people feel 3G is necessary: For $30 a month? Please. I'm already accustomed to limiting my laptop internet use to readily available free wi-fi. Why do I expect anything different with the iPad? Most anyplace I have time to sit and read/use a computer (cafe, airport, you house, library, etc.) has free wi-fi. I can live without web surfing in your car. That's what the iPhone is for. -- Don't like that not everyone was ready in day one: I'm looking at you Facebook. No iPad app for launch? Lame. iPhone apps scaled-up to work on the iPad look grainy and cheap. Not a quality befitting this beautiful $700 piece of glass.Verdict: I'm bringing it to COLLABORATE 08 and seeing if I can go the whole week using only the iPad. If I can trade this thing for my laptop, I know it's a winner. For now, I'm enjoying Popular Science.

• Does your analytic solution tell you what questions to ask?

  - by Manan Goel

  Analytic solutions exist to answer business questions. Conventional wisdom holds that if you can answer business questions quickly and accurately, you can take better business decisions and therefore achieve better business results and outperform the competition. Most business questions are well understood (read structured) so they are relatively easy to ask and answer. Questions like what were the revenues, cost of goods sold, margins, which regions and products outperformed/underperformed are relatively well understood and as a result most analytics solutions are well equipped to answer such questions. Things get really interesting when you are looking for answers but you don’t know what questions to ask in the first place? That’s like an explorer looking to make new discoveries by exploration. An example of this scenario is the Center of Disease Control (CDC) in United States trying to find the vaccine for the latest strand of the swine flu virus. The researchers at CDC may try hundreds of options before finally discovering the vaccine. The exploration process is inherently messy and complex. The process is fraught with false starts, one question or a hunch leading to another and the final result may look entirely different from what was envisioned in the beginning. Speed and flexibility is the key; speed so the hundreds of possible options can be explored quickly and flexibility because almost everything about the problem, solutions and the process is unknown.  Come to think of it, most organizations operate in an increasingly unknown or uncertain environment. Business Leaders have to take decisions based on a largely unknown view of the future. And since the value proposition of analytic solutions is to help the business leaders take better business decisions, for best results, consider adding information exploration and discovery capabilities to your analytic solution. Such exploratory analysis capabilities will help the business leaders perform even better by empowering them to refine their hunches, ask better questions and take better decisions. That’s your analytic system not only answering the questions but also suggesting what questions to ask in the first place. Today, most leading analytic software vendors offer exploratory analysis products as part of their analytic solutions offerings. So, what characteristics should be top of mind while evaluating the various solutions? The answer is quite simply the same characteristics that are essential for exploration and analysis – speed & flexibility. Speed is required because the system inherently has to be agile to handle hundreds of different scenarios with large volumes of data across large user populations. Exploration happens at the speed of thought so make sure that you system is capable of operating at speed of thought. Flexibility is required because the exploration process from start to finish is full of unknowns; unknown questions, answers and hunches. So, make sure that the system is capable of managing and exploring all relevant data – structured or unstructured like databases, enterprise applications, tweets, social media updates, documents, texts, emails etc. and provides flexible Google like user interface to quickly explore all relevant data. Getting Started You can help business leaders become “Decision Masters” by augmenting your analytic solution with information discovery capabilities. For best results make sure that the solution you choose is enterprise class and allows advanced, yet intuitive, exploration and analysis of complex and varied data including structured, semi-structured and unstructured data.  You can learn more about Oracle’s exploratory analysis solutions by clicking here.

• Graphics trouble after resuming from hibernate or suspend

  - by Voyagerfan5761

  I have a Dell Inspiron 2650 (with NVidia graphics, using nouveau drivers) that I'm using to try out Ubuntu. It's all great, except that Hibernate and Suspend aren't usable. Yes, I know that questions about power-save issues are rampant in the Linux support universe, but it seems that every time I find a solution it's for a very specific hardware combination and doesn't apply to me. So anyway, here goes. When I resume from either power-saving mode, I'll get graphics problems anywhere on the range from a few scattered random-colored pixels that won't change; all the way to full-screen patterns that don't change as I move the mouse, hit keys on the keyboard, or even bring up the shutdown dialog using the power button. Those full-screen issues (which may involve stripes with random pixels, partial black screen, or both) always end in me forcing the machine to shut down by holding the power button. I haven't done much testing yet to determine what severity level is most commonly associated with each mode, but I do avoid using either power-save option because of these issues. I'll add info on my hardware as I can gather it (no home internet connection, and this laptop is tethered to my desk by a dead battery and casing degradation). Please feel free to request something specific in the question comments. Hardware Info See this hardinfo report for my system's hardware configuration. (No, my username is not "myuser"; I sanitized hardinfo's output before publishing it.) Screenshots These screenshots are from a relatively mild occurrence, which happened after the second hibernation I took that session. The first one worked great, though I used the wireless card and Firefox heavily between the two hibernation attempts. Take a look at what happened when I opened my home directory in Nautilus and scrolled it: See below for the situations I've tested so far. The real trouble comes when the machine resumes to an unusable state; in such cases I can't even unlock the screen or properly reboot, much less take a screenshot. I have a hunch that putting a CD in the drive will cause such major failures, and I will try that at some point; see related question. Situations Tested Maverick (10.10) Suspend Seems to suspend nicely with nothing running Seems to suspend nicely with flash drive plugged in On resume from suspend with no flash drive, Terminal and gedit running: Funky graphics on top of log output, then blank screen with pixelated cursor; no response to power button (normally will shutdown 60 seconds later) Hibernate Seems to hibernate nicely with nothing running Seems to hibernate nicely with a few apps (Terminal, Mouse preferences) running Seems to not hibernate when flash drive plugged in Seems to not hibernate when System Monitor is running Have encountered failed hibernation (after several hours and one successful hibernate/thaw cycle) with no external media connected and no programs running except normal background stuff Natty LiveCD (11.04_2010-12-22) When I tested it, Natty wouldn't stay logged in. It played part of the login sound and then [ OK ] appeared in the top right corner (white-on-black terminal text) for a few seconds. Then it kicked me back to the Unlock screen. It did that four times before I gave up and just tested suspend from the Unlock screen. Suspend Resumed to vertical gray and black lines 2px (?) wide, then shifted to vertical "jail bars" of black over a black screen with above-described random pixels and mouse pointer. No apparent response to input from mouse (clicking randomly). Keyboard and touchpad unrecognized.

• CGImageCreateWithMask with an image as a mask

  - by Peyman

  Hi I am trying to use an image (painted as Core Graphics) to create a mask. What I am doing is this 1. creating a Core Graphics path CGContextSaveGState(context); CGContextBeginPath(context); CGContextMoveToPoint(context,circleCenter.x,circleCenter.y); //CGContextSetAllowsAntialiasing(myBitmapContext, YES); CGContextAddArc(context,circleCenter.x, circleCenter.y,circleRadius,startingAngle, endingAngle, 0); // 0 is counterclockwise CGContextClosePath(context); CGContextSetRGBStrokeColor(context,1.0,0.0,0.0,1.0); CGContextSetRGBFillColor(context,1.0,0.0,0.0,0.2); CGContextDrawPath(context, kCGPathFillStroke); 2. then I'm saving the context that has the path just painted CGImageRef pacmanImage = CGBitmapContextCreateImage (context); 3. restoring the context CGContextRestoreGState(context); CGContextSaveGState(context); 4. creating a 1 bit mask (which will provide the black-white mask) bitsPerComponent = 1; bitsPerPixel = bitsPerComponent * 1 ; bytesPerRow = (CGImageGetWidth(imgToMaskRef) * bitsPerPixel); mask = CGImageCreate(CGImageGetWidth(imgToMaskRef), CGImageGetHeight(imgToMaskRef), bitsPerComponent, bitsPerPixel, bytesPerRow, greyColorSpace, kCGImageAlphaNone, CGImageGetDataProvider(pacmanImage), NULL, //decode YES, //shouldInterpolate kCGRenderingIntentDefault); 5. masking the imgToMaskRef (which is a CGImageRef imgToMaskRef =imgToMask.CGImage;) with the mask just created imageMaskedWithImage = CGImageCreateWithMask(imgToMaskRef, mask); CGContextDrawImage(context,imgRectBox, imageMaskedWithImage); CGImageRef maskedImageFinal = CGBitmapContextCreateImage (context); returning the maskedImageFinal to the caller of this method (as wheelChoiceMadeState, which is a CGImageRef) who then updates the CALayer contents property with the image theLayer.contents = (id) wheelChoiceMadeState; the problem I am seeing is that the mask does not work properly and looks very strange indeed. I get strange patterns across the path painted by the Core Graphics. My hunch is there is something with CGImageGetDataProvider() but I am not sure. Any help would be appreciated thank you

• Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

  - by LucasTizma

  I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

• Zend framework "invalid controller" error message

  - by stef

  When I load the homepage of a ZF site I get a message saying "Invalid controller specified (error)" where "error" seems to be the name of the controller. In my bootstrap.php I have the snippet below where I added the prints statement in the catch(): // Dispatch the request using the front controller. try { $frontController->dispatch(); } catch (Exception $exception) { print $exception; exit; exit($exception->getMessage()); } This prints out: exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (error)' in /www/common/ZendFramework/library16/Zend/Controller/Dispatcher/Standard.php:241 Stack trace: #0 /www/common/ZendFramework/library16/Zend/Controller/Front.php(934): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #1 /www/site.com/htdocs/application/bootstrap.php(38): Zend_Controller_Front->dispatch() #2 /www/site.com/htdocs/public/index.php(16): require('/www/site....') #3 {main} Can anyone make sense out of what it going on? I have a hunch it has something to do with case sensitivity and the naming conventions of ZF. The initial "invalid controller" message comes from the snippet below print $request->getControllerName(); if (!$this->isDispatchable($request)) { $controller = $request->getControllerName(); if (!$this->getParam('useDefaultControllerAlways') && !empty($controller)) { require_once 'Zend/Controller/Dispatcher/Exception.php'; throw new Zend_Controller_Dispatcher_Exception('Invalid controller specified (' . $request->getControllerName() . ')'); } $className = $this->getDefaultControllerClass($request); } This all prints out "indexerrorInvalid controller specified (error)" so it looks like it's trying to load the index controller first, can not and then has a problem loading the error controller. Could it just be that the path to the controller files is wrong?

• Best approach to storing image pixels in bottom-up order in Java

  - by finnw

  I have an array of bytes representing an image in Windows BMP format and I would like my library to present it to the Java application as a BufferedImage, without copying the pixel data. The main problem is that all implementations of Raster in the JDK store image pixels in top-down, left-to-right order whereas BMP pixel data is stored bottom-up, left-to-right. If this is not compensated for, the resulting image will be flipped vertically. The most obvious "solution" is to set the SampleModel's scanlineStride property to a negative value and change the band offsets (or the DataBuffer's array offset) to point to the top-left pixel, i.e. the first pixel of the last line in the array. Unfortunately this does not work because all of the SampleModel constructors throw an exception if given a negative scanlineStride argument. I am currently working around it by forcing the scanlineStride field to a negative value using reflection, but I would like to do it in a cleaner and more portable way if possible. e.g. is there another way to fool the Raster or SampleModel into arranging the pixels in bottom-up order but without breaking encapsulation? Or is there a library somewhere that will wrap the Raster and SampleModel, presenting the pixel rows in reverse order? I would prefer to avoid the following approaches: Copying the whole image (for performance reasons. The code must process hundreds of large (= 1Mpixels) images per second and although the whole image must be available to the application, it will normally access only a tiny (but hard-to-predict) portion of the image.) Modifying the DataBuffer to perform coordinate transformation (this actually works but is another "dirty" solution because the buffer should not need to know about the scanline/pixel layout.) Re-implementing the Raster and/or SampleModel interfaces from scratch (but I have a hunch that I will be unable to avoid this.)

• Locating memory leak in Apache httpd process, PHP/Doctrine-based application

  - by Sam

  I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?
