• Links not opening in Windows 8 applications

  - by Martin Brown

  I have just upgraded my laptop from Windows 7 Ultimate with IE9 to Windows 8 with IE 10. When ever I try to open a web link in an application nothing happens. For example in the Windows 8 mail application it makes the email address in an email look like a link. When I click on these with the mouse the link changes to look like I have clicked on it, but aside from that nothing happens. I have tried making sure that IE 10 is my default web browser and been into IE10's settings and associated it with all the usual file types, but still no success. Has anyone got any ideas what might be causing this? I have a feeling this started when the Browser Choice update ran. I couldn't select which browser to install in that either. The install buttons just flashed when I clicked them and then nothing. PS I would have added an IE10 tag to this post, but apparently I don't have the reputation required to do so.

• Power supply surges detected during previous power on

  - by Blastcore

  Message is this: "Power supply surges detected during previous power on" "ASUS Auto-Surge was triggered to protect system from unstable power supply" When i went to sleep yesterday and woke up, when i moved the mouse to go back from screen saver, it didn't do anything. So i left it, i came back from class and got this issue. (I didn't restart before going to class... So the screen was left like it was) Today there was a power cut in half of my house. (Computer is on the side that it didn't cut...) Voltages are fine, like always. How do i remove message? It's just maybe sensor glitch? Even disabling the Anti-Surge my PC "shuts down" (Only monitor, but maybe components do too.)

• How do I memoize expensive calculations on Django model objects?

  - by David Eyk

  I have several TextField columns on my UserProfile object which contain JSON objects. I've also defined a setter/getter property for each column which encapsulates the logic for serializing and deserializing the JSON into python datastructures. The nature of this data ensures that it will be accessed many times by view and template logic within a single Request. To save on deserialization costs, I would like to memoize the python datastructures on read, invalidating on direct write to the property or save signal from the model object. Where/How do I store the memo? I'm nervous about using instance variables, as I don't understand the magic behind how any particular UserProfile is instantiated by a query. Is __init__ safe to use, or do I need to check the existence of the memo attribute via hasattr() at each read? Here's an example of my current implementation: class UserProfile(Model): text_json = models.TextField(default=text_defaults) @property def text(self): if not hasattr(self, "text_memo"): self.text_memo = None self.text_memo = self.text_memo or simplejson.loads(self.text_json) return self.text_memo @text.setter def text(self, value=None): self.text_memo = None self.text_json = simplejson.dumps(value)

• Are speakers wasting power when they are not in use?

  - by Dennis Cheung

  I guess all of you have a pair/set of speakers for your MP3s. I am just interesting to how do they do when they are not playing? How actually the power spent by the speaker? Does any the below cases matter? Idle / Silence input When you computer is off / not connected Raise the volume by hardware (turn/push the button on the speaker) Raise the volume by software (do it with your mouse) BTW, to save the world. I am here to suggest you to unplug it when you leave your PC.

• Bulk "open with" change on OS X 10.6

  - by railmeat

  I use Microsoft remote desktop to connect from my mac to the windows machine I work on. I have a directory with about 50 different rdp files. (The config files for each machine). They go changed to open with the remote desktop in Windows XP on Parallels. Is there a command I can use to change all those back to opening with the remote desktop on my Mac? I can use the right mouse click "Always open with" command, or the equivalent on the "Get Info" menu, but I would like to find a way to make that change in bulk. "Change All..." button on the "Get Info" menu does not have any effect.

• Issue with python string join.

  - by Pradyot

  I have some code in which I apply a join to a list. The list before the join looks like this: ["'DealerwebAgcy_NYK_GW_UAT'", "'DealerwebAgcy'", "'UAT'", '@ECNPhysicalMarketCo nfigId', "'GATEWAY'", "'DEALERWEB_MD_AGCY'", "'NU1MKVETC'", "'mkvetcu'", "'C:\te mp'", '0', "'NYK'", '0', '1', "'isqlw.exe'", 'GetDate()', '12345', "'NYK'", '350 ', '7'] After the join this is the resulting string 'DealerwebAgcy_NYK_GW_UAT','DealerwebAgcy','UAT',@ECNPhysicalMarketConfigId,'GAT EWAY','DEALERWEB_MD_AGCY','NU1MKVETC','mkvetcu','C: emp',0,'NYK',0,1,'isqlw. exe',GetDate(),12345,'NYK',350,7 Note the element "'C:\temp'" which ends up as ,'C: emp', I tried something similar on the python command prompt , but I wasn't able to 2 repeat this. the relevant code responsible for this magic is as follows. values_dict["ECNMarketInstance"] = [strVal(self.EcnInstance_),strVal (self.DisplayName_) ,strVal(self.environment_), '@ECNPhysicalMarketConfigId', strVal(self.EcnGatewaTypeId_),strVal(self.ConnectionComponent_) ,strVal(self.UserName_),strVal(self.Password_),strVal(self.WorkingDir_),"0",strVal(self.region_),"0","1", strVal(self.LUVersion_), "GetDate()" , self.LUUserId_ ,strVal(self.LUOwningSite_),self.QuoteColumnId_ , self.Capabilities_] delim = "," joined = delim.join(values) print values print joined

• Computer Studdering When Transferring Over Network

  - by Nalandial

  This is a really weird problem that I've never even seen before. When I copy to or from my server share, my computer studders terribly and the data transfers very slowly at only around 12MB/s. By studdering I mean the mouse skips around and all my applications respond very slowly; as soon as I cancel the transfer it resolves immediately. I looked at Task Manager and the CPU is only at ~35% with plenty of RAM free. This only started semi-recently; before, I had no problems and the transfer speed maxed out the gigabit connection. I have two hard drives in my computer. When I try transferring files between drives it's fine, but when I copy from the share to either drive or to it from either drive, I get studdering. I'm running Windows 7 x64. Anyone have any idea what's going on? Any help would be much appreciated.

• Hot Link To A Specific Cell Comment In Excel 2007

  - by Optimal Solutions

  Is there a way to create a comment for cell D7 (for example) such that when the user hovers over it the comment has a hot link or hyperlink to cell A100? I dont know what else to call it other than a hot link or hyperlink, however its not like the hyperlink we know of in HTML. Or, maybe it could it be? The effect that is desired is that when the user sees that comment, he/she can click on the link to cell A100 if they choose to do so. I do not wish to create a macro or use VBA behind a button, etc.. It must be within the comment box itself. One of the issues I have run into is that once you move the mouse, the comment goes away. The comment might be able to be displayed all the time if it needs to be for this to work.

• Asus EeePC X101CH Touchpad issue

  - by ssvarc

  I have an Asus EeePC X101CH that the touchpad was uninstalled from (I saw the uninstall dialog boxes open). After a restart there was a PS/2 mouse under View Hidden Devices in Device Manager that wasn't installed properly (I'm assuming that this is the touchpad). Going to the Asus website and downloading the drivers (V15.3.27.1), I get the error message "Synaptics device not found!". I tried the other driver Version v9.1.7.7 for the Sentelic TouchPad as well (when run it appears to be the driver for the finger sensing) and got the error message "This driver version is inapplicable for the touch pad. Please check the devices on the system and install the suitable driver.". What's my next step? Thanks!

• Synergy on Mac OS X 10.7

  - by matt

  Unfortunately, I can't seem to get Synergy to work between two Mac clients both using 10.7. One is an older 21" iMac and the other is a new 2011 Macbook Air. Here's my synergy.conf, symlinked to my home directory as ~/.synergy.conf section: screens foo: bar: super = alt alt = super end section: links foo: right = bar bar: left = foo end That is, I thought the super = alt trick was mandatory in order to have alt work on Mac but unfortunately, nothing really works. Both the Command and Control keys do NOT work on bar but work fine on foo given that the keyboard is paired with that screen. The keyboard modifier keys are the same on both computers and the making the mouse go between screens works as well. I was wondering if anyone else had any success or problems running into this issue on 10.7 and was hoping there was a possible fix.

• Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

  - by Omer Raviv

  Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

• Non-USB powered laptop cooling pad?

  - by Andrei Rinea

  On my laptop (el-cheapo but pretty good) I have all my 3 USB ports occupied by devices in use (external mouse, external keyboard, 3G internet/flash drive/external hard drive/etc). I want a cooling pad for my hard-worked laptop but all seem to be powered by USB... This laptop is mainly stationary. Either is available a solution to power the USB-powered cooling pad other than connecting it to the laptop... ... either is there a non-USB powered laptop cooling pad?

• WinXP keyboard input repeat rate problem

  - by Victor Sorokin

  I have problem similar to http://superuser.com/questions/33981/problems-with-kvm-switch-and-keyboard-repeat-rate-on-windows-xp: When I press and hold some key it's repeated random number of times, after that repeat stops and I need to release key and press it again to make repeat continue. If there's simultaneous sound playback and repeat is stopped, sound's stuck while I hold key with unpleasant drumming as if there's some audio problem. This issue is reproducible in WinXP Safe Mode. On the same config under Linux there's no issue. My config: List item PS/2 Logitech Keyboard USB Mouse MB M3A/H-HDMI WinXP Pro English SP2 with added Russian layout (WinXP loads via GRUB2) Realtek audio drivers for AC97 Thanks for your suggestions J

• How to see ALT text in Firefox

  - by torbengb

  I know Mozilla thinks it's a bug that IE shows ALT text even after the image has loaded; while users think it's a bug that Firefox doesn't work exactly like IE. This disagreement is irrelevant to my question: How can I make my Firefox show the ALT tooltip when I hover the mouse over an image? Obviously XKCD is a bit tame without this essential functionality. I've tried the Firefox plugin Popup ALT Attribute but it doesn't work; after restarting the browser and hovering over an image with an ALT text, no tooltip appears. I reproduced this on several computers with several (Windows) OS versions.

• Multi-part gzip file random access (in Java)

  - by toluju

  This may fall in the realm of "not really feasible" or "not really worth the effort" but here goes. I'm trying to randomly access records stored inside a multi-part gzip file. Specifically, the files I'm interested in are compressed Heretrix Arc files. (In case you aren't familiar with multi-part gzip files, the gzip spec allows multiple gzip streams to be concatenated in a single gzip file. They do not share any dictionary information, it is simple binary appending.) I'm thinking it should be possible to do this by seeking to a certain offset within the file, then scan for the gzip magic header bytes (i.e. 0x1f8b, as per the RFC), and attempt to read the gzip stream from the following bytes. The problem with this approach is that those same bytes can appear inside the actual data as well, so seeking for those bytes can lead to an invalid position to start reading a gzip stream from. Is there a better way to handle random access, given that the record offsets aren't known a priori?

• after upgrade to outlook 2013 Contacts have the default picture in reading pane

  - by Juan Zamudio

  I'm using Windows 8 on a domain (using a domain account not a Microsoft account) connecting to Exchange, all my Contacts were outlook contacts with pictures and other data, I could see the picture of the contact in the reading pane and people pane while using Outlook 2010. After the upgrade to Outlook 2013 I can see my outlook contacts but it appears that they are unavailable in the reading pane because all i can see is the default picture (the default picture picture is also visible in the notifications). If I put the mouse over the name of the people while in the reading pane all I can see is the card with the default info (the only data is that the contact is available in the next 8 hours), if i compose a new message and hover the name of the contact i can see the card with all the data (picture, company, etc.). Is this the default behavior in Outlook 2013 if you are in a domain and not connected to any service or there is a way to show the picture of my contacts in every part of outlook?

• XSD NewDataSet Namespace?

  - by Ian

  I'm running XSD on an XML file and getting something strange. Depending on the depth of elements it produces a 'NewDataSet' element which will then is prefixed in Visual Studio to my auto-generated classes which is something I don't want. I've got quite a complex structure and am just trying to add a simple version element or attribute which is causing the problem. The simplest demo I could come up with is this. <A> <B>Text</B> </A> Running this through XSD says there is an element called 'NewDataSet' which may or may not appear and will prefix namespaces. <A> <B> <C>Text</C> </B> </A> This example works as expected and there is no magic 'NewDataSet' element in the generated XSD file.

• Where to put X11 drivers configuration in Ubuntu Lucid?

  Since hal is removed from Lucid, where now can I put all those little configuration tweaks for mouse and other input devices? In particular, I want to configure ThinkPad trackpad to enable scrolling with middle button.

• What is the best software for desktop recording?

  - by Ivo Flipse

  I know this question is partially a stub from: http://superuser.com/questions/201/free-desktop-recording-screencasting-on-windows However I would have to use this at work, so it doesn't have to be free, just work very well. Lended from the free post: I would expect such an application to have these features: choose the whole desktop, a region, a window to record zoom in an area, and camera move save the recorded movie to a compressed format have basic editing tools have the mouse highlighting feature highlight window/field on the screen, any trick will do display pressed keys/key combinations (like iphone does) So the question is: Which desktop recording/screencasting software would you recommend?

• How do you balance business process changes against the challenges of changing software?

  - by Achilles

  In my admittedly young career I've found myself writing code to support quirky business rules and processes. Inevitably these changes were always in some massively difficult code base and caused many issues. My question has a couple of parts: While software is a tool for businesses to make their lives easier, at what point do we as developers suggest a change in business process rather than in the software as the "magic bullet" to solve a particular problem. How do we as developers evangelize a certain level of reverence for the software as well as the difficulty involved in making changes simply to support the quirks of the business? I understand that these changes in business processes promote our industry, but in an analogy my father would understand: Which is easier, to melt down a hammer to forge a screwdriver to drive screws or to simply use nails since your hammer is already awesome...?

• How to change drag & drop behaviour in Windows 7's explorer?

  - by Pekka

  I have a new touch screen, and am playing around with its functionality. The most productive use for me is organizing files (literally) by hand. It's fun working through a list of files, dragging and dropping them to the right locations using your index finger. It feels better on the wrist than mouse-clicking, too. The only problem is that when I drag & drop files across drives in Windows 7, the default behaviour is to copy the file instead of moving it. I know I can influence this using right click, but that is of course no option in my situation. How can I change the default drag & drop behaviour in Windows 7's explorer?

• Windows Live Mail doesn't respond to clicking Allow Sender

  - by Karel

  This is a problem that I experience for a couple of years now.. I'm having the latest version of Windows Live Mail. The overall behavior works just fine, but when I want to click 'Allow Sender' in the yellow bar above my e-mail, the text button does nothing. My mouse pointer turns into a finger hand, but the click event does nothing.. Sometimes with other e-mails, the button works and the yellow bar dissappears.. I have also experienced this in previous versions of Windows Live Mail.. Does anybody know what it could be..

• Making a non-trivial Image and Video Gallery with a really nice interface

  - by Cawas

  Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

• How to disable horizontal scrolling within virtualbox on Ubuntu guest, Windows 7 host?

  - by Steven Rosato

  I am using Windows 7 as Host, Ubuntu Karmic as guest OS with guest tools installed and I get an annoying glitch when switching from host to the guest machine: Vertical scrolling switches to horizontal! (using the mouse wheel). Since I don't really care about horizontal scrolling, how can I disable this? I have checked the web and the only thing I found was to play in the xorg.conf file and adding in the section "InputDevice" Option "ZAxisMapping" "4 5" which would enable vertical scrolling only. The thing is, I don't have that section in my config file so I guessed that I would need to add Section "InputDevice" Identifier "VBoxMouse" Driver "vboxmouse" Option "ZAxisMapping" "4 5" EndSection But that does not seem to work after restarting xserver. Any workaround for this?
