• Debugging OpenOffice crashes

  - by JD Long

  This is partly an OpenOffice question and partly a Ubuntu question. I'm running OpenOffice 3.2.0 and Ubuntu 10.04. I get frequent crashes of OO, especially the Calc app, although I get crashes in the word processor as well. They are very abrupt and accompanies by no warning or error message. I'm just typing away and then the app is gone. Sometimes I even end up thinking I'm typing in OO and discover that OO has crashed and I'm typing in whatever application was under OO. However, I can't reproduce these crashes on demand. They seem random. I can open the same file and do the same exact thing but it does not crash. In Ubuntu how do I trace, track, or diagnose these types of crashes? Is there software I can invoke to help diagnose? Can I start OO from a command prompt with debugging of some sort enabled? Note: if someone could add the tag OpenOffice, I would appreciate it

• Good Blog Software

  - by Darren Young

  Hi, Inspired from an earlier question regarding starting a blog, I have decided to start one myself. I only have 4 months commercial experience in C#, but I am hoping to use my blog as a tool for further learning. Maybe such things as researching and writing about a different design pattern each week, a tricky aspect of C# that I don't yet fully understand, etc, etc. My question is, can somebody recommend any good blog sites suited for writing text and code? Is there any that allow the use of code tags or similar for formatting? Thanks,

• Connecting my iPhone to iTunes causes my Acer laptop to crash

  - by Paul Sheldrake

  Hello I have an Acer Travelmate 8200 laptop and whenever I connect my Iphone to it, it crashes with the BSOD(Blue Screen Of Death). I have figured out that if I delete all the pictures in my phone I can get it to connect but that is not a ideal long term solution. I also read that it may be a conflict with the built in web-cam I have but I've upgraded the driver and I still get the crashing problem. Any suggestions would be appreciated! Thanks Paul! edit: Here is the BSOD message I get

• Project Management Techniques (high level)

  - by Sam J

  Our software dev team is currently using kanban for our development lifecycles, and, from the reasonably short experience of a few months, I think it's going quite well (certainly compared to a few months ago when we didn't really have a methodology). Our team, however, is directed to do work defined by project managers (not software project managers, just general business), and they're using the PMBOK methodology. Question is, how does a traditional methodology like PMBOK, Prince2 etc fit with a lean software development methodology like kanban or scrum? Is it just wasting everyone's time as all the requirements are effectively drawn up to start with (although inevitably changed along the way)?

• Is there a name for this issue?

  - by Epicmaster

  I was just talking to my partner about how hard it is to personally judge how good your product is after a while because you use it so often. You literally spend hours on your computer doing nothing but work on this Consumer Facing application, and you start to feel a little fatigue of using it over and over and over, at least a hundred times a day. You get scared this fatigue may mean the product you are building may have the same effect on the users and might mean you are doing something wrong. All i'm asking is, is there a name for this in product development? For the fact that as a designer+ programmer+everything else, your product might not suck as much as you think simply because you spend way to much time with it, or a variation of this?

• 5 Ways To Quickly Launch Programs On Windows

  - by Chris Hoffman

  Do you still launch programs on Windows by hunting down a desktop shortcut and double-clicking it? There are better ways – Windows has several built-in tricks for quickly launching applications. Even if you know all the built-in tricks, you may want to try out Launchy or another third-party launcher – some people swear by them. They offer more features than the Start menu search built into Windows. HTG Explains: Is ReadyBoost Worth Using?

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• How to Effectively Create Bullet Patterns

  - by SoulBeaver

  I'm currently creating a top-down shooter like Touhou. The most important factor of the game is that there are many diverse patterns and ways at which bullets are generated and shot at the player, see this video: http://www.youtube.com/watch?v=4Nb5Ohbt1Sg#start=0:60;end=9:53; At the moment, I'm using a class "Pattern" which has a series of steps on moving and shooting. However, I feel this method is quite laborous as I have to create a new Pattern for each attack and perhaps new Bullet classes that will implement a certain behavior. This question received a comment suggesting I should look into BulletML for easy creation and storage of bullets with a specific pattern. It looks decent, but it led me to wonder, what other solutions do you have that I should take into consideration? Update My current design is as follows: An example of an implemented pattern: My GigasPattern first executes a teleport which moves Alice to a certain point (X, Y) on the screen. After this is completed, the pattern starts using the Mover to move the sprite around (whereas teleporting has separate effects and animation). These are of no concern, really, as they are quite simple. The Shooter also creates various Attacks, which are classes again that the Shooter can use to create various patterns of bullets, much like the one in the question I posted. Once the Mover has reached it's destination, both it and the shooter stop and return to an inactive state. The pattern completes, is removed by the AI and a new one gets chosen.

• iOS calendar sync with Exchange 365

  - by Patrick J Collins

  I signed up for an Exchange 365 account with Microsoft Online. I followed the instructions to set up my iPhone to access my mail. However, I can't access the calendar function. When I go into the account settings screen on my iPhone, the options to turn on the calendar, contacts and reminders are missing! (See step 9 on this site to get an idea of what the dialog should look like). Anyone have an idea why those options are missing and how I could activate them? Thanks, Patrick

• Old Lock Retrofitted for Wireless and Key-free Entry

  - by Jason Fitzpatrick

  What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.

• DVI to HDMI - displaying bad.

  - by TutorialPoint

  I currently have a computer with a ASUS EAH5770 (ATi Radeon HD 5770) 1GB GDDR5 video card, and 4GB ram, 2.6 GHZ i5 processor. I just switched from a DVI (the blue one) to an HDMI cable. (Bigben Flat cable HDMI 1.3c) I use a Samsung SyncMaster 2032 MW, which has a HDMI input. The weird thing is, that my screen is off-the-corner of the tv (so it's too wide) (1920x1080), and windows icons and text are not displaying well, though 1080p videos in YouTube are looking brilliant, just like pictures. So i think it has something to do with Windows. I already have the ATI Catalyst Control Center with the drivers i received with my video card. I do not currently know how to fix these problems. Do i have to reinstall Windows or so? Or is it (hopefully) easier?

• How do I separate model positions from view positions in MVC?

  - by tieTYT

  Using MVC in games (as opposed to web apps) always confuses me when it comes to the view. How am I supposed to keep the model agnostic of how the view is presenting things? I always end up giving the Model a position that holds x and y but invariably, these values end up being in units of pixels and that feels wrong. I can see the advantage* of avoiding that but how am I supposed to? This idea was suggested: Don't think of it in units of pixels, think of them in arbitrary distance units that just happen map to pixels at a 1:1 ratio. Oh, the resolution is half of what it was? We are now taking the x/y coordinates at 50% value for screen display, and your spells casting range is still 300 units long, which now is 150 pixels. But those numbers conveniently work out. What do I do if the numbers divide in such a way that I get decimal places? Floating points are unsafe. I think allowing decimal places would eventually cause really weird bugs in my game. *It'd let me write the model once and write different views depending on the device.

• Need to isnatll windows 7 on dual boot machine

  - by user108451

  I have dual boot configured with Windows 7 (32bit) and Ubuntu 12.04(64bit). I installed Ubuntu after windows, now my windows is corrupt due to some virus and I need to reinstall it. Currently when I start my PC, grub loader comes up and I need to select Ubuntu or Windows. I was wondering how can I install windows again and still have my Ubuntu install? Is there a way to do this? I do not want to install Ubuntu again and lose my settings and data there. Thanks, Ketan

• Learning C, Lisp, and UNIX from Ground Up

  - by hunterc

  A friend and I are trying to learn traditional programming from the ground up. We both do web stuff primarily but want to expand to more system related things. We have found a ton of resources but looking for a road map of sorts. We are planning on using SICP to learn Lisp(scheme). Don't really know where to from there. As for C, we figured we'd start with K&R, then do OOC, and sprinkle in Operating Systems Design and Implementation and kind of learn UNIX as we go. I'd really appreciate suggestions on filling in the gaps, reordering things, or just advice in general.

• Implementing Ads on any page in your Windows 8 XAML app–part 2

  - by nmarun

  In my previous article , you saw how you can start implementing ads on some of the page templates. In this one, we’ll see how we can add something called ‘interstitial ads’ – ads that appear as part of the content in your app. I have added a Grouped Items page to my project. My data model is set to show a few appliances. I have a BaseModel class and the ApplianceModel that inherits the BaseModel class has two properties to represent an appliance. The ProductHolder acts as a container for a list of...(read more)

• How to solve this problem with a 'tuned' prompt in ZSH?

  - by Mnementh

  I have an adjusted prompt in my ZSH-configuration. Main feature is, that this prompt is colored red, so that I can easily it distinguish from the outputs of programs. My prompt is defined as follows: PROMPT=$'\e[0;31m%n@%m:%~> \e[0m' This works mostly fine, but sometimes my cursor switches to another position on tab-completion and some characters are left behind on the screen and mangle up the commandline. That is a little annoyance, but if someone knows a solution for this, I would appreciate it.

• Dual HDD dual boot Win7/Win7 hibernate corrupts partitions?

  - by Ivan Zlatev

  I have two SSDs in my laptop. Both have 2 partitions each one with Windows 7 64bit and another one with OEM stuff on it (SYSTEM_DRV). I use the BIOS boot menu to boot between the drives. I have removed the drive letters so that no partitions of drive 1 are mapped in windows 2 on drive 2 and wise-versa. What I have observered however is that when I hibernate windows 1, boot windows 2 do some work and shutdown then resume windows 1 - the windows 2 partition will get corrupt quite often. Just happened actually - it is shown as "RAW" in the Disk manager instead of NTFS and windows will blue screen at boot. Alternatively I've seen cases where chkdsk will run and will wipe out all security descriptors making the partition completly unbootable. Why am I seeing these corruptions and what can I do to prevent them?

• Is the 4pin atx power plug required [closed]

  - by rockinthesixstring

  I know the answer is probably a resounding YES, but I just wanted to double check. I just purchased a new chassis for my PC and now my 4pin cpu power plug doesn't reach. I'm wondering if the 4 pins are required for operation, or can I get by for the weekend without it until I can go get an extension? EDIT: Looks like it is mandatory with my Mobo. I tried to post without it and i just got a blank screen. Looks like I'm getting a new adapter asap.

• HP Envy dv6t-7300: Disabled WiFi through button and can't enable it anymore

  - by Mateus B. Cassiano

  Well, I have a HP Envy dv6t-7300 laptop that came with a Ralink RT5390 WiFi card. Everything was working perfectly, and eventually I press the WiFi button in my keyboard to toggle the card on/off. Until today, all worked right: if the wifi was off (wifi LED amber) and I press the wifi button, after a few seconds the LED turn white and everything works. If I repeat the process, the wifi LED turn amber and the card get disabled, but now, I can't turn it on anymore. running sudo rfkill list all I get: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes So, I ran sudo rfkill unblock all but nothing changed. As a side note, if I run sudo ifconfig wlan0 up, the indicator LED gets white (indicating that the card was enabled), but Ubuntu still say that the card is blocked by hardware. Extra information: the card works without issues in windows and in Ubuntu installer (booting from a live CD). I'm using the card out-of-box, using the drivers already included in Ubuntu 12.10. The module rt2800pci is loaded and working fine, not blacklisted, etc, etc. The card and the button toggle worked flawlessly until today, when I toggled it off and can't turn it on anymore... The problem is back, but in a different manner: if I don't press the wifi key a few times during the grub loading, in the login screen the wifi button will be ambar (disabled), pressing it will toggle it white (enabled) or ambar (disabled) again, but ubuntu still says that the network card was disabled by hardware and doesn't connect... In other words, if I don't press the WiFi button a few times when Ubuntu is booting, it will be stuck with the "network card was disabled by hardware" message, even if the light is white (enabled). Any clue? Maybe a error in some startup script or config file?

• Fast determination of whether objects are onscreen in 2D

  - by Ben Ezard

  So currently, I have this in each object's renderer's update method: float a = transform.position.x * Main.scale; float b = transform.position.y * Main.scale; float c = Camera.main.transform.position.x * Main.scale; float d = Camera.main.transform.position.y * Main.scale; onscreen = a + width - c > 0 && a - c < GameView.width && b + height - d > 0 && b - d < GameView.height; transform.position is a 2D vector containing the game engine's definition of where the object is - this is then multiplied by Main.scale to translate that coordinate into actual screen space Similarly, Camera.main.transform.position is the in-engine representation of where the main camera is, and this is also multiplied by Main.scale The problem is, as my game is tile-based, thousands of these updates get called every frame, just to determine whether or not each object should be drawn - how can I improve this please?

• Coding events. What they actually are about, and are they worth it?

  - by BKC

  I'm a relatively new programmer, but am very much interested in it. I enrolled to this coding event (Yahoo! Hack India, to be precise), and got invited after the pre-coding contest. The event is like a contest where developers create an application in 24 hours, In group or individually. I've never been to such an event before, and certainly don't know anyone who did. So, here are my questions. First of all, is it worth it? What if we don't get any ideas in the first place to start with? I'm not actually a developer, I'm an electrical engineering student who just completed his 2nd semester. So will be able to match up to the level of other developers who will be there? Any other advice/suggestions Thank you in advance.

• Dual Monitor 'How To' for 12.04

  - by Kim Prince

  I recently built my own PC and was delighted with the result, except for a problem with dual monitors. After having tried a few different combinations of hardware, I think what I really need is a 'how to' explanation. My motherboard is an MSI Z77MA-G45, which has an analogue, a DVI, and a HDMI port. Initially I hooked monitors up to the DVI and analogue port and it seemed to work fine. Both screens worked independently of each other, it was great. After a few days I started turning my PC off at night, and when I tried to turn it back on it would boot into the terminal mode. I would have to turn one of the monitors off and after rebooting a few times, it would eventually boot into an X Window session. Occasionally I would see an error relating to Xorg. I upgraded the motherboard BIOS but that made no difference. Eventually, I installed a graphics card - an NVIDIA GeForce GT 520. Now it seems that my on board graphics have been disabled completely, and I am reliant on the graphics card. Furthermore, the graphics card seems to only recognise one screen at a time. (The first time I rebooted with both plugged in, it flashed up a message saying that it was auto-selecting DVI). Anyhow, I think I need some 'how to' (or perhaps 'where to'), from here. For example, is X Windows configuration the next place to look? And how do I go about configuring X Windows? (Note that in Systems Settings it says my graphics driver is 'unknown', and when I ask it to detect monitors, it sees only the one!)

• Problem with installing Nvidia display drivers on Ubuntu 13.10

  - by Pascal

  Hello everyone and thank you for taking a look at this topic! I'm currently trying out Ubuntu 13.10 but I keep hitting a wall when it comes to installing a driver. I've tried: sudo apt-get install nvidia-current This resulted in a un-bootable system. The screen just stayed black and the cursor displayed as an 'X'. After that I did had to re-install Ubuntu. The computer I'm using is an Acer-Aspire-V3 with a build in Nvidia geforce GT 630M and also with a Intel HD graphics chip-set (not sure if chip-set is the right word here). "lspci | grep VGA" output: pascal@pascal-Aspire-V3-571G:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) I've searched a bit here and there and found out that it would be wise to mention that this laptop is using (or so I think) Nvidia Optimus, not sure if it will add anything to the subject but at least I'll mention it just to be sure. Now to the questions: Q1 How is this caused and how can I fix it? Q2 What additional information could I provide to help you help me?

• How to limit my CPU power programmatically on Windows 7?

  - by Ivan

  Whenever I run a CPU-heavy activity (like compressing a big set of files into an archive for example) my CPU switches to its full throttle (maximum frequency) and shuts down of overheat in less than a minute. Instead, I would like it to keep slowed-down slightly to do the task a bit slower but be able to reach the finish. At the same time I don't want to dim my screen brightness or adjust anything else what standard Windows power-saving system does. So how do I actually set a cap to limit my CPU power? The CPU is Core 2 Duo T7250, the OS is Windows 7 32-bit, there seem to be no BIOS settings or jumpers available to configure the frequencies.
